abstract = {Nudging users to keep them secure online has become a growing research field in cybersecurity. While existing approaches are mainly blackbox based, showing aggregated visualisations as one-size-fits-all nudges, personalisation turned out promising to enhance the efficacy of nudges within the high variance of users and contexts. This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

One prominent approach for measuring spillover effects is based on the analysis of patent citation networks. Taking social media analytics and knowledge economics into account, this paper presents a complementary approach to quantify spillover effects from defense to civilian research and development, analyzing 513 employment biographies from the social network LinkedIn. Using descriptive network analysis, we investigate the emigration of personnel of the German defense industry to other civilian producers. Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

abstract = {Since the emergence of so-called fake news on the internet and in social media, platforms such as Facebook have started to take countermeasures, and researchers have begun looking into this phenomenon from a variety of perspectives. A large number of scientific work has investigated ways to detect fake news automatically. Less attention has been paid to the subsequent step, i.e., what to do when you are aware of the inaccuracy of claims in social media. This work takes a user-centered approach on means to counter identified mis- and disinformation in social media. We conduct a three-step study design on how approaches in social media should be presented to respect the users' needs and experiences and how effective they are. As our first step, in an online survey representative for some factors to the German adult population, we enquire regarding their strategies on handling information in social media, and their opinion regarding possible solutions — focusing on the approach of displaying a warning on inaccurate posts. In a second step, we present five potential approaches for countermeasures identified in related work to interviewees for qualitative input. We discuss (1) warning, (2) related articles, (3) reducing the size, (4) covering, and (5) requiring confirmation. Based on the interview feedback, as the third step of this study, we select, improve, and examine four promising approaches on how to counter misinformation. We conduct an online experiment to test their effectiveness on the perceived accuracy of false headlines and also ask for the users' preferences. In this study, we find that users welcome warning-based approaches to counter fake news and are somewhat critical with less transparent methods. Moreover, users want social media platforms to explain why a post was marked as disputed. The results regarding effectiveness are similar: Warning-based approaches are shown to be effective in reducing the perceived accuracy of false headlines. Moreover, adding an explanation to the warning leads to the most significant results. In contrast, we could not find a significant effect on one of Facebook's current approaches (reduced post size and fact-checks in related articles).},

Social media allow emergency services to reach the public easily in the context of crisis communication and receive valuable information (e.g. pictures) from social media data. However, the vast amount of data generated during large-scale incidents can lead to issues of information overload and quality. To mitigate these issues, this paper proposes the semi-automatic creation of alerts including keyword, relevance and information quality filters based on cross-platform social media data. We conducted empirical studies and workshops with emergency services across Europe to raise requirements, then iteratively designed and implemented an approach to support emergency services, and performed multiple evaluations, including live demonstrations and field trials, to research the potentials of social media-based alerts. Finally, we present the findings and implications based on semi-structured interviews with emergency services, highlighting the need for usable configurability and white-box algorithm representation.},

Our representative survey of 7,071 citizens in Europe (Germany, Italy, the Netherlands and the United Kingdom) shows differences of current use of social media in emergencies, expectations towards authorities monitoring social media, intensity of perceiving barriers regarding the use as well as variances concerning the (likelihood of future) use of mobile apps. While German and British participants' frequency of use of social media is medium and low, respectively, Italian and Dutch respondents use them relatively frequently. Our comparison of the four countries allows for an interpretation of divergent behavior across countries with respect to risk cultures as well as expanding the respective model to social media contexts. At the same time, our findings stress that across the four European countries participants assessed similar advantages like dissemination of information and barriers like false rumors with respect to use social media during emergencies. Distributed equally across nations, age and gender showed significant relationships with social media usage which, among other findings, suggests being helpful for effective implementation of management structures using new technologies.},

In contrast, false rumours on social media (74\%) are perceived as a threat.

First, we present the results of an empirical study about informal work and mobile collaboration practices of emergency services. Then we describe the concept of a mobile geo-collaboration system that addresses the aspects detected in the empirical study and that was implemented as an Android application using web sockets, a technology enabling full-duplex ad hoc communication. Finally we outline the findings of its evaluation in practice and its implications.},

This paper examines the use of social media during the European Floods of 2013 and proposes a novel cross-social-media application for volunteers. Besides comprehensive analysis of volunteer communities, interviews were conducted with "digital volunteers" such as Facebook moderators of disaster-related groups. Based on the challenges identified, we designed and implemented the cross-social-media application "XHELP", which allows information to be both, acquired and distributed cross-media and cross-channel. The evaluation with 20 users leads to further design requirements for applications aiming to support volunteer moderators during disasters.},

With our research we consider real and virtual volunteers in order to detect conditions for cooperation among those citizen groups through social media. Therefore we analysed the usage of Twitter during a tornado crisis to look for role patterns and aspects that helped volunteer groups in the virtual to emerge, and matched the data with an interview study on experiences, attitudes, concerns and potentials professional emergency services recounted in the emergence of volunteer groups in the real. While virtual groups seem to easily form and collaborate, the engagement of real volunteers is decreasing according to the perception of professionals. We discuss the dynamics in both tendencies and suggest design implications (use of existing social networks, promotion and awareness, connection among volunteers, connection to emergency services and systems) to support both types of volunteer groups, which lead to a software prototype.},

Die Auswirkungen auf die Gesellschaft und Wirtschaft sind verheerend. Parallel lassen sich Krisenereignisse im digitalen Raum, wie die Zunahme an Cyberkriminalität beobachten. Es wird zunehmend deutlich, dass die Resilienz analoger sowie digitaler Prozesse wichtiger für die vollständige Betriebsfähigkeit wird. Die vorliegende Arbeit setzt sich mit der Bedeutung des Resilient Smart Farming (RSF) in Krisenzeiten als Möglichkeit für eine nachhaltige, umweltgerechte und resiliente digitale Landwirtschaft auseinander. Dazu wurden u.a. lokale Schadensmeldungen gruppiert und mögliche RSF-Gegenmaßnahmen aufgezeigt. Im Ergebnis zeigt sich eine Bewertung von Konzepten des RSF hinsichtlich der Krisenprävention und -bewältigung anhand aktueller realer Beispiele. Aufgrund zunehmender Bedrohungen durch Naturkatastrophen und Cyberkriminialität gehen wir davon aus, dass die Aufmerksamkeit von Gesellschaft und Politik für die Resilienz der Primärproduktion weiter steigen wird.},

By conducting a system-atic literature review, we build a recent list of attacks, as well as collect mitigationoptions. Taking a look at a concrete use case (IoT in agriculture) allows us to evaluatethe practicality of both exploiting the vulnerabilities and implementing the counter-measures. We detected 16 attacks that we grouped into six attack types. Along withthe attacks, we collect countermeasures for attack mitigation. Developers can use ourfindings to minimize the risks when developing applications based on LoRaWAN.These mostly theoretical security recommendations should encourage future worksto evaluate the mitigations in practice.},

abstract = {Past studies in the domains of information systems have analysed the potentials and barriers of social media in emergencies. While information disseminated in social media can lead to valuable insights, emergency services and researchers face the challenge of information overload as data quickly exceeds the manageable amount. We propose an embedding-based clustering approach and a method for the automated labelling of clusters. Given that the clustering quality is highly dependent on embeddings, we evaluate 19 embedding models with respect to time, internal cluster quality, and language invariance. The results show that it may be sensible to use embedding models that were already trained on other crisis datasets. However, one must ensure that the training data generalizes enough, so that the clustering can adapt to new situations. Confirming this, we found out that some embeddings were not able to perform as well on a German dataset as on an English dataset.},

abstract = {In many cases of machine learning, research suggests that the development of training data might have a higher relevance than the choice and modelling of classifiers themselves. Thus, data augmentation methods have been developed to improve classifiers by artificially created training data. In NLP, there is the challenge of establishing universal rules for text transformations which provide new linguistic patterns. In this paper, we present and evaluate a text generation method suitable to increase the performance of classifiers for long and short texts. We achieved promising improvements when evaluating short as well as long text tasks with the enhancement by our text generation method. In a simulated low data regime additive accuracy gains of up to 15.53\% are achieved. As the current track of these constructed regimes is not universally applicable, we also show major improvements in several real world low data tasks (up to +4.84 F1 score). Since we are evaluating the method from many perspectives, we also observe situations where the method might not be suitable. We discuss implications and patterns for the successful application of our approach on different types of datasets.},

However, the exact relationship between privacy and security behavior is rarely discussed in the literature. This study investigates this relationship and the role of socio-demographic factors (gender, age, education, political opinions) in such behavior. Exploratory results of a survey of German private users (N=1,219) show that privacy and security behavior are only weakly correlated and not similarly influenced by socio-demographic factors. While se-curity behavior significantly differs between age and education groups (younger and less educated show less security behavior), no such differences exist for pri-vacy behavior. Additionally, political orientation and opinion has no influence on privacy and security behavior. Thus, this study sheds light on the concepts of privacy, security and corresponding behavior and emphasizes the need for a fine-grained differentiation if either privacy or security behavior is to be improved.},

abstract = {Phishing is a prevalent cyber threat, targeting individuals and
organizations alike. Previous approaches on anti-phishing
measures have started to recognize the role of the user, who,
at the center of the target, builds the last line of defense.
However, user-oriented phishing interventions are fragmented
across a diverse research landscape, which has not been
systematized to date. This makes it challenging to gain an
overview of the various approaches taken by prior works.
In this paper, we present a taxonomy of phishing interventions
based on a systematic literature analysis. We shed light
on the diversity of existing approaches by analyzing them
with respect to the intervention type, the addressed phishing
attack vector, the time at which the intervention takes place,
and the required user interaction. Furthermore, we highlight
shortcomings and challenges emerging from both our literature
sample and prior meta-analyses, and discuss them in
the light of current movements in the field of usable security.
With this article, we hope to provide useful directions for
future works on phishing interventions.},

This article presents a disaggregated whitebox-based visualisation of critical information as a novel nudge. By segmenting users according to their decision-making and information processing styles, we investigate if the novel nudge is more effective for specific users than a common black-box nudge. Based on existing literature about critical factors in password security, we designed a dynamic radar chart and parallel coordinates as disaggregated visualisations. We evaluated the short-term effectiveness and users' perception of the nudges in a think-aloud prestudy and a representative online evaluation (N=1.012). Our findings suggest that dynamic radar charts present a moderately effective nudge towards stronger passwords regarding short-term efficacy and are appreciated particularly by players of role-playing games.},

At the same time, policing is criticised for becoming increasingly militarised and for having extended surveillance in the course of fighting terrorism.

In this study, we conduct a representative survey of the German population to investigate personal experiences with and attitudes towards the police and information and communication technologies (ICT) used for policing. We find an overall positive image of the police and uncritical attitudes towards ICT used for general surveillance (body-worn cameras, video surveillance, face recognition) and slightly more critical attitudes towards personal surveillance (e.g. through communication data retention). The study indicates that perceptions differ according to experience of unfair treatment by the police, while other factors such as age and education have similar effects.},

abstract = {Digitalisierung ist ein präsenter Faktor in vielen Städten. So existieren bereits viele Smart-City-Initiativen, bei denen Städte versuchen, ihre Prozesse durch Erfassung und Verknüpfung von Daten, oft unter Zuhilfenahme von Datenplattformen, zu optimieren. In Anbetracht der damit einhergehenden großen Investitionen und Veränderungen wird Bürgerbeteiligung als zentraler Faktor für den Erfolg solcher Initiativen betrachtet. Bisher ist allerdings nicht klar, was typische Beteiligungsformate von Smart-City-Initiativen sind und welche Rolle(n) BürgerInnen dabei einnehmen. Dieser Beitrag leitet mittels einer Literaturanalyse zu Smart Cities ein Kategorienschema zu typischen Bürgerbeteiligungsarten ab. Die Analyse ergab, dass sich Einbindung von BürgerInnen in politische Entscheidungen und bei der Entwicklung technischer Artefakte maßgeblich auf e‑Government oder Participatory Design bezieht. Im Hinblick auf die Beteiligungsarten zeigt sich, dass Makrofabriken, Living Labs und Open-Data-Plattformen häufige Ansätze sind, um BürgerInnen als Co-Creators einzubinden. Zudem werden BürgerInnen mit Citizen Sensing zur Erfassung von Daten oder Missständen einbezogen. Dabei zeigen sich sowohl aktivere, als auch eher passive Beteiligungsarten. Die Analyse zeigt, dass die Einbindung von BürgerInnen häufig entweder auf eine Beteiligung an politischen Entscheidungen oder an der Entwicklung technischer Artefakte abzielt. Auch wenn keine klare Abgrenzung möglich ist, sind diese Ansätze dann eher durch e‑Government oder Participatory Design inspiriert.},

Through a repeated one-week survey with closed and open questions of German citizens during the beginning of the COVID-19 pandemic, this study examines citizens' perceptions of information responsibilities, their satisfaction with the fulfillment of these responsibilities and their wishes for improving the information flow. The study shows that the dynamism of the crisis and the federally varying strategies burden citizens who perceive an obligation to stay informed, but view agencies as responsible for making information readily available. The study contributes a deeper understanding of citizens' needs in crises and discusses implications for design of communication tools for dynamic situations that reduce information overload while fulfilling citizens' desire to stay informed.},

Thus, Computer Emergency Response Teams (CERTs) are deployed in many countries and organisations to enhance the preventive and reactive capabilities against cyberattacks. However, their tasks are getting more complex by the increasing amount and varying quality of information dissem-inated into public channels. Adopting the perspectives of Crisis Informatics and safety-critical Human-Computer Interaction (HCI) and based on both a narrative literature review and group discussions, this paper first outlines the research agenda of the CYWARN project, which seeks to design strategies and technolo-gies for cross-platform cyber situational awareness and actor-spe-cific cyber threat communication. Second, it identifies and elabo-rates eight research challenges with regard to the monitoring, analysis and communication of cyber threats in CERTs, which serve as a starting point for in-depth research within the project.},

In several domains, such as crisis management or political communication, it is of utmost importance to detect false and to promote credible information. Although educational measures might help individuals to detect false information, the sheer volume of social big data, which sometimes need to be anal- ysed under time-critical constraints, calls for automated and (near) real- time assessment methods. Hence, this paper reviews existing approaches before designing and evaluating three deep learning models (MLP, RNN, BERT) for real-time credibility assessment using the example of Twitter posts. While our BERT implementation achieved best results with an accuracy of up to 87.07\% and an F1 score of 0.8764 when using meta- data, text, and user features, MLP and RNN showed lower classification quality but better performance for real-time application. Furthermore, the paper contributes with a novel dataset for credibility assessment.},

Previous work has shown that machine readable information is either missing, incorrect, or inconsistent with other data sources. In this paper, we introduce a system called Overt Vulnerability source ANAlysis (OVANA), utilizing state-of-the-art machine learning (ML) and natural-language processing (NLP) techniques, which analyzes the information quality (IQ) of vulnerability databases, searches the free-form description for relevant information missing from structured fields, and updates it accordingly. Our paper shows that OVANA is able to improve the IQ of the National Vulnerability Database by 51.23\% based on the indicators of accuracy, completeness, and uniqueness. Moreover, we present information which should be incorporated into the structured fields to increase the uniqueness of vulnerability entries and improve the discriminability of different vulnerability entries. The identified information from OVANA enables a more targeted vulnerability search and provides guidance for IT security experts in finding relevant information in vulnerability descriptions for severity assessment.},

Sollte sich ein Landwirt beispielsweise während eines lokalen Krisenfalls, wie einem Ausfall des Mobilfunknetzes oder des Internetzugangs des Betriebs, auf dem Feld aufhalten, wird ein alternativer Kommunikationskanal benötigt, um weiterhin eine Verbindung zu IT-Komponenten und benötigten Daten herstellen zu können. Mit der zunehmenden Digitalisierung finden Low-Power-Wide-Area-Network (LPWAN)-Technologien immer häufiger Anwendung, beispielsweise durch den Aufbau von Sensornetzwerken. Die eingesetzten LPWANTechnologien bieten dabei eine hohe Reichweite und sind größtenteils autark einsetzbar, erlauben jedoch keine klassische TCP/IP-Kommunikation. Im Rahmen dieser Arbeit wird experimentell eine populäre LPWAN-Technologie, namentlich LoRaWAN, durch AX.25 auf OSI-Schicht 2 (Data Link Layer) ergänzt, um Endgeräten eine TCP/IP-basierte Kommunikation über weite Strecken zu erlauben. Die Evaluation zeigt, dass klassische Anwendungen mit niedriger Bandbreite somit funktionsfähig sind und krisentaugliche Datenübertragung in landwirtschaftlichen Betrieben ermöglichen können.},

For example, if a farmer is in the field during a network outage, such as a failure of the mobile network, an alternative communication channel is needed to continue to connect to IT components and required data. With increasing digitalization, Low Power Wide Area Network (LPWAN) technologies are being used more and more frequently, e.g. for sensor networks. The LPWAN technologies offer a high range and can be used autonomously for the most part, but do not allow classic TCP/IP communication. In this work, a popular LPWAN technology, namely LoRaWAN, is experimentally supplemented by AX.25 on OSI layer 2 (Data Link Layer) to allow end devices TCP/IP-based communication over long distances. The evaluation shows that classic low-bandwidth applications are thus functional and can enable reliable, crisis-capable data transmission.},

abstract = {Technological progress can disrupt domains
and change the way we work and collaborate. This paper presents a qualitative study with 52 German farmers
that investigates the impact of the ongoing digitalization process in agriculture and discusses the implications for privacy research. As in other domains, the introduction of digital tools and services leads to the data
itself becoming a resource. Sharing this data with products along the supply chain is favored by retailers and
consumers, who benefit from traceability through transparency. However, transparency can pose a privacy risk.
Having insight into the business data of others along the
supply chain provides an advantage in terms of market
position. This is particularly true in agriculture, where
there is already a significant imbalance of power between actors. A multitude of small and medium-sized
farming businesses are opposed by large upstream and
downstream players that drive technological innovation.
Further weakening the market position of farmers could
lead to severe consequences for the entire sector. We
found that on the one hand, privacy behaviors are affected by adoption of digitalization, and on the other
hand, privacy itself influences adoption of digital tools.
Our study sheds light on the emerging challenges for
farmers and the role of privacy in the process of digitalization in agriculture.},

abstract = {The revelation of the Stuxnet malware in 2010 shed light on the presence of state actors that are willing and capable of developing and using highly sophisticated, specialized malicious software for their political interests. These tools -often dubbed cyber weapons -are expected to become the next major advancement in weaponry technology. Besides the threats of offensive cyber operations for civil IT systems due to the interconnected nature of the cyberspace, international regulation of cyber weapons is -among other aspects -hindered by the fact that the military development and the strategic and tactical deployment of cyber weapons differ significantly from other weapons technologies. In order to establish measures of cyber arms related control treaties, it is crucial to identify these particular characteristics. Based on this premise, the article analyzes the current perspectives on cyber weapons, identifying their weaknesses of being either based on assumptions about adversarial actors or being applicable only after the usage of a malicious tool. In contrast to these approaches, the article focuses on the specific functional aspects of malware and presents an indicator-based assessment model based on parameters that can be measured prior to the application of malicious software. This enables the categorization of malicious tools as cyber weapons. Besides this, the article aims to introduce thought-provoking impulses with regard to social responsibility in computer science.},

The motor of digitalization can be social necessity, technical feasibility, and also a crisis, as the reaction to the COVID-19 pandemic demonstrates: Out of necessity, ideas are created, systems designed and implemented and the value of digital solutions to society becomes apparent. With the digitalization of everyday working and learning, apps for tracing information chains and containing new infections have potential, but also pose social risks. The current COVID-19 crisis seems to put the role of digitalization in a completely new light. Both, to evaluate the value of digital solutions to society and to identify space for innovation is important in times of intense digitalization efforts.
To meet the societal challenges posed by digitalization, it is particularly important to understand how they arise. The use of digital solutions in safety-critical contexts entails dependencies and the threat of various dangers: Infrastructure disruptions and failures can be caused by criminal acts, terrorist attacks, natural disasters, operational disruptions, and system failures. In addition, there is a concern about data arising from the use of digital solutions. Data protection, data sovereignty, data security, and their social perception must always be closely observed. Furthermore, it is important to ensure that digitalization does not lead to a digital divide. New digital solutions require constant evaluation and assessment of the consequences.},

In den darauf-folgenden Jahren, vor allem aber dem letzten Jahrzehnt, wurde eine Vielzahl von Stu-dien veröffentlicht, die sich auf den Gebrauch von Informations- und Kommunikations-technologien einschließlich der sozialen Medien vor, während oder nach Notfällen kon-zentrieren. Dieser Forschungsbereich wird auch unter dem Begriff Crisis Informatics zusammengefasst. Das Ziel dieses Kapitels ist es, den Gebrauch von und die Forschung über soziale Medien in Katastrophen und Notfällen in den vergangenen 20 Jahren mit besonderem Schwerpunkt auf identifizierbare Nutzungsmuster und deren Wahrnehmung zusammenzufassen, um die bisherigen Ergebnisse und zukünftigen Potenziale herauszu-stellen.},

abstract = {Receiving relevant information on possible cyber threats, attacks, and data breaches in a timely manner is crucial for early response. The social media platform Twitter hosts an active cyber security community. Their activities are often monitored manually by security experts, such as Computer Emergency Response Teams (CERTs). We thus propose a Twitter-based alert generation system that issues alerts to a system operator as soon as new relevant cyber security related topics emerge. Thereby, our system allows us to monitor user accounts with significantly less workload. Our system applies a supervised classifier, based on active learning, that detects tweets containing relevant information. The results indicate that uncertainty sampling can reduce the amount of manual relevance classification effort and enhance the classifier performance substantially compared to random sampling. Our approach reduces the number of accounts and tweets that are needed for the classifier training, thus making the tool easily and rapidly adaptable to the specific context while also supporting data minimization for Open Source Intelligence (OSINT). Relevant tweets are clustered by a greedy stream clustering algorithm in order to identify significant events. The proposed system is able to work near real-time within the required 15-minutes time frame and detects up to 93.8\% of relevant events with a false alert rate of 14.81\%.},

abstract = {Besides the merits of increasing digitization and interconnectedness in private and professional spaces, critical infrastructures and societies are more and more exposed to cyberattacks. In order to enhance the preventative and reactive capabilities against cyberattacks, Computer Emergency Response Teams (CERTs) are deployed in many countries and organizations. In Germany, CERTs in the public sector operate on federal and state level to provide information security services for authorities, citizens, and enterprises. Their tasks of monitoring, analyzing, and communicating threats and incidents is getting more complex due to the increasing amount of information disseminated into public channels. By adopting the perspectives of Computer-Supported Cooperative Work (CSCW) and Crisis Informatics, we contribute to the study of organizational structures, technology use, and the impact on collaborative practices in and between state CERTs with empirical research based on expert interviews with representatives of German state CERTs (N=15) and supplementary document analyses (N=25). We derive design and policy implications from our findings, including the need for interoperable and modular architecture, a shift towards service level agreements, cross-platform monitoring and analysis of incident data, use of deduplication techniques and standardized threat exchange formats, a reduction of resource costs through process automation, and transparent reporting and tool structures for information exchange.},

Using descriptive network analysis, we investigate the emigration of personnel of the German defense industry to other civilian producers. Thereby, our study reveals that in the last decade, employees of defense suppliers have changed positions significantly less often, with 3.24 changes on average than professionals who have worked more than 50\% of their jobs in the civilian sector, having changed 4.61 times on average. Our work illustrates the churn behavior and how spillover effects between defense and civilian sectors can be measured using social career networks such as LinkedIn.},

These migration movements increas-ingly rely on digital infrastructure, such as mobile internet access and online services, in order to reach theirtargeted destination countries. Asylum seekers often use smartphones for information and communicationpurposes. Even though there are many positive aspects in the use of such technologies, researchers have toconsider the perceived risks of this specific user group. This work aims at investigating the use of mobileinformation technologies by asylum seekers during their flight, especially taking privacy into account. Thus, itexamines asylum seekers’ digital privacy perceptions and identifies privacy protection behaviors by conductinga qualitative interview study with 14 asylum seekers who applied for asylum in Germany. The results showthat asylum seekers are often aware of the various risks deriving from the use of smartphones and ICT, suchas surveillance and persecution by state or non-state actors as well as extortion by criminals. Based on this,this work furthermore outlines different strategies used to manage these risks. Since the lack of privacy andtrust leads to avoidance behavior, the insights of this study provide valuable information for the design ofassistance apps and collaboration platforms, which appropriately address the specific needs for digital privacyin the context of flight, or for the conception of privacy-enhancing technologies helping to achieve this.},

Recent research has highlighted, on the one hand, the use of social media as a means of recruitment by terrorists and, on the other hand, the use of Facebook, Twitter etc. to gain the support of the population during insurgencies. This article conducts a qualitative content analysis of content on Twitter concerning the conflict in the Jammu and Kashmir region. The tweets following the death of a popular militant, Burhan Wani, cover three different themes: (1) criticism of intellectuals, (2) Burhan Wani's impact on the conflict, and (3) tweets referring to the conflict itself. Generally, people use Twitter to make their own point of view clear to others and discredit the opposing party, at the same time tweets are reflecting the antagonism between the two parties to the conflict, India and Pakistan. The sample of tweets reflects the lack of awareness among people in the region regarding the motivations of the new generation of militancy emerging in Kashmir after 1990.},

Basing our questionnaire on a workshop with police officers, we present the results of a representative study on citizens' perception of social media in emergencies that we conducted in Germany. Our study suggests that when it comes to emergencies, socio-demographic differences are largely insignificant and no clear preferences for emergency services' social media strategies exist. Due to the widespread searching behavior on some platforms, emergency services can reach a wide audience by turning to certain channels but should account for groups with distinct preferences.},

Additionally, we ana- lyze the role of socio-demographic factors (gender, age, education, political ori- entation) for security knowledge and behavior. Results show that German pri- vate users have only moderate IT security knowledge and behavior, with as- pects as gender, age, education and political orientation partly having an influ- ence. Men, higher educated and politically moderately oriented participants show higher security knowledge, whereas young people and those less knowl- edgeable about security behave less security-conscious. Additionally, security knowledge and behavior correlate moderately. Therefore, to increase private users' IT security we suggest to increase education and training especially for users being young, politically right-wing or female.},

abstract = {The research field of crisis informatics examines, amongst others, the potentials and barriers of social media use during disasters and emergencies. Social media allow emergency services to receive valuable information (e.g., eyewitness reports, pictures, or videos) from social media. However, the vast amount of data generated during large-scale incidents can lead to issue of information overload. Research indicates that supervised machine learning techniques are sui- table for identifying relevant messages and filter out irrelevant messages, thus mitigating in- formation overload. Still, they require a considerable amount of labeled data, clear criteria for relevance classification, a usable interface to facilitate the labeling process and a mechanism to rapidly deploy retrained classifiers. To overcome these issues, we present (1) a system for social media monitoring, analysis and relevance classification, (2) abstract and precise criteria for re- levance classification in social media during disasters and emergencies, (3) the evaluation of a well-performing Random Forest algorithm for relevance classification incorporating metadata from social media into a batch learning approach (e.g., 91.28\%/89.19\% accuracy, 98.3\%/89.6\% precision and 80.4\%/87.5\% recall with a fast training time with feature subset selection on the European floods/BASF SE incident datasets), as well as (4) an approach and preliminary eva- luation for relevance classification including active, incremental and online learning to reduce the amount of required labeled data and to correct misclassifications of the algorithm by feed- back classification. Using the latter approach, we achieved a well-performing classifier based on the European floods dataset by only requiring a quarter of labeled data compared to the tradi- tional batch learning approach. Despite a lesser effect on the BASF SE incident dataset, still a substantial improvement could be determined.},

Based on a workshop with civil protection (N=12) and police officers (N=15), we designed a questionnaire and conducted a representative survey of German citizens (N=1.219) on the past, current and future use, perceived helpfulness, deployment and behavioural preferences, configurability and most important functionality of mobile crisis apps. Our results indicate that in addition to emergency and weather warnings, crime- and health-related warnings are also desired by many, as is the possibility for bidirectional communication. People also want one central app and are resistant to installing more than one crisis app. Furthermore, there are few significant differences between socioeconomic groups.},

abstract = {Since the emergence of so-called fake news on the internet and in social media, platforms such as Facebook have started to take countermeasures, and researchers have begun looking into this phenomenon from a variety of perspectives. A large number of scientific work has investigated ways to detect fake news automatically. Less attention has been paid to the subsequent step, i.e., what to do when you are aware of the inaccuracy of claims in social media. This work takes a user-centered approach on means to counter identified mis- and disinformation in social media. We conduct a three-step study design on how approaches in social media should be presented to respect the users' needs and experiences and how effective they are. As our first step, in an online survey representative for some factors to the German adult population, we enquire regarding their strategies on handling information in social media, and their opinion regarding possible solutions — focusing on the approach of displaying a warning on inaccurate posts. In a second step, we present five potential approaches for countermeasures identified in related work to interviewees for qualitative input. We discuss (1) warning, (2) related articles, (3) reducing the size, (4) covering, and (5) requiring confirmation. Based on the interview feedback, as the third step of this study, we select, improve, and examine four promising approaches on how to counter misinformation. We conduct an online experiment to test their effectiveness on the perceived accuracy of false headlines and also ask for the users' preferences. In this study, we find that users welcome warning-based approaches to counter fake news and are somewhat critical with less transparent methods. Moreover, users want social media platforms to explain why a post was marked as disputed. The results regarding effectiveness are similar: Warning-based approaches are shown to be effective in reducing the perceived accuracy of false headlines. Moreover, adding an explanation to the warning leads to the most significant results. In contrast, we could not find a significant effect on one of Facebook's current approaches (reduced post size and fact-checks in related articles).},

abstract = {Betrachtet man Landwirtschaft unter dem Blickwinkel kritischer Infrastruktur, da sie einen essenziellen Bestandteil der lebenswich-tigen Nahrungsmittelproduktion darstellt, so wird schnell klar, dass auch die dort eingesetzten Werkzeuge hohen Anforderungen stand-halten müssen. Mit dem Einsatz moderner digitaler Werkzeuge werden Erwartungen verbunden, sowohl den gesellschaftlichen Anforderungen nach Qualität und Quantität von Nahrungsmitteln gerecht zu werden, als auch dabei die Produktion möglichst effi-zient unter Berücksichtigung von Umwelt und Natur durchzufüh-ren. Ebenso gilt es die Interessen der landwirtschaftlich Beschäftig-ten zu wahren. Die Geobox-Infrastruktur verfolgt dieses Ziel. Zu den wichtigsten Aspekten, die dabei erfüllt werden müssen, zählen eine resiliente Systemarchitektur, Sicherheit und Datenhoheit, aber auch Gebrauchstauglichkeit. Dieser Beitrag diskutiert den For-schungsansatz sowie zentrale Anforderungen.},

Vor allem mobile Anwendungen haben im Laufe der letzten Jahre immer mehr an Relevanz gewonnen. Aufgrund vielfältiger Einsatzmöglichkeiten müssen hier diverse Disziplinen zusammenwirken, um die Kooperation zwischen Menschen und Maschinen sicher und effizient zu gestalten. Doch auch die Zusammenarbeit zwischen Menschen wird zunehmend technologisch unterstützt, was sich u.a. in der steigenden Popularität sozialer Medien widerspiegelt. Mithilfe solcher Systeme kann eine Kommunikation, Awareness und Koordination insbesondere in der Krisenbewältigung angestrebt und erreicht werden, sie bringen aufgrund ihrer teilweise technischen Komplexität aber auch Probleme mit sich. Im Zentrum dieses Workshops stehen Erkenntnisse zur Mensch-Computer-Interaktion in sicherheitskritischen Anwendungsgebieten.},

abstract = {Soziale Medien werden auf der ganzen Welt genutzt. Vergleicht man die allgemeine Nutzung sozialer Medien im Vereinigten Königreich (GB), Deutschland (DE), den Niederlanden (NL) und Italien (IT), zeigt sich, dass sie in Italien am
wenigsten in Anspruch genommen werden. Dort sind knapp
40 \% der Bevölkerung, d. h. 37 Millionen Menschen, in den
sozialen Medien aktiv. Sowohl im Vereinigtem Königreich
(59 \%, 39 Mio.), Deutschland (55 \%, 45 Mio.) als auch den Niederlanden (57 \%, 9,74 Mio.) lassen sich ähnliche Tendenzen
erkennen. Angesichts der Tatsache, dass mobile Endgeräte,
die tendenziell immer griffbereit sind, sehr häufig zur Kommunikation über soziale Medien eingesetzt werden, ist es
nicht verwunderlich, dass diese auch in Notsituationen genutzt werden [8]. Bis dato fehlt es an aussagekräftigen
quantitativen und vergleichbaren Ergebnissen aus unterschiedlichen Ländern über die Wahrnehmung der Bevölkerung zur Nutzung von sozialen Medien in Notsituationen.
Die im Folgenden vorgestellte Studie „The Impact of
Risk Cultures: Citizens’ Perception of Social Media Use in
Emergencies across Europe” [9] mit Beteiligung der TU
Darmstadt, Universität Siegen und dem Tavistock Institute
(London), möchte das bestehende Defizit adressieren. Anhand der repräsentativen Umfrageergebnisse werden zunächst vier europäische Länder präsentiert und dann miteinander verglichen. Ziel ist es, Ähnlichkeiten und Unterschiede in der Nutzung sozialer Medien in Notsituationen
zu erfassen. Frühere Forschungsergebnisse haben im Hinblick auf Katastrophen gezeigt, dass es unterschiedliche
Risikokulturen in europäischen Ländern gibt, die das Verhalten der Bevölkerung jeweils unterschiedlich beeinflussen
und prägen (vgl. [4]; [5]).},

As more and more people live in urban areas and urban services and infrastructures are under growing strain, technologies are increasingly being researched and used to make city life more efficient and comfortable. As a result, so-called “Smart Cities” have complex IT infrastructures and cyber-physical systems such as sensor/actuator networks for the general population and are developing worldwide. Urban infrastructure must be secured against attacks, ensuring reliable and resilient services for citizens as well as privacy and data security. This paper introduces selected challenges faced by infrastructure providers, citizens and decision-makers in handling attacks aimed at information and communication technologies (ICT) of urban infrastructures and presents current research avenues for tackling cyberattacks and for developing tools for creating, portraying and disseminating actiona-ble information as one important response to security challenges. It then presents findings from a representative survey conducted in Germany (N=1091) on the experiences and perceptions of citizens concerning the relevance of cyberat-tacks will be presented.},

Sie beschäftigt sich auf der Grundlage von Erkenntnissen aus verschiedenen Naturwissenschaften und technischen Fachrichtungen (z. B. Physik, Chemie, Biologie, Informatik) mit der Rolle naturwissenschaftlicher und technischer Möglichkeiten im Kontext von Krieg und Frieden sowie Rüstung und Abrüstung. Sie unterstützt die politischen Prozesse der Kriegsprävention, der Abrüstung und der Vertrauensbildung mit Analysen der Eigenschaften und Folgen neuer Waffenarten und Technologien. Aus dieser Forschung werden Vorschläge für die Begrenzung neuer Waffenentwicklungen ebenso entwickelt wie technische Lösungen für eine verbesserte Rüstungskontrolle.

To provide empirical evidence we present a comparison of two surveys, conducted across Europe with emergency services in 2014 and 2017 respectively, with a total of 1169 answers. The analysis shows that personal experience has an effect on how organisational usage of social media is perceived and how emergency service staff view the future use of social media. Furthermore, the use has increased. This article not only shows emergency services what their staff think about their social media usage but also discusses challenges and future directions for the design of systems that can be useful for further development of optimized organisational social media usage.},

abstract = {The debate on the development and deployment of lethal autonomous weapon systems (LAWS) as an emerging technology is of increasing importance, with discussions stalling and technological development progressing. Monitoring the progress of increasingly autonomous weapons systems in civilian and military use as well as regulating possible autonomous systems early on is demanded by civil society actors, like the Campaign to Stop Killer Robots and the International Committee of the Red Cross (ICRC), while nation states follow a variety of interests and strategies, showing little room for consensus on central terms and questions [2], [3]. This article therefore sheds light on the work of the Group of Governmental Experts (GGE) of the UN Convention of Certain Conventional Weapons (CCW). The CCW, offering an arena for international cooperation, has dedicated itself to the purpose of finding common ground with respect to an understanding of LAWS, as well as to the necessary degree of human control. From an ethical perspective, the concept of Meaningful Human Control (MHC) supports a human-centric approach. Several IEEE projects, series and publications are dedicated to this prioritization, especially regarding civilian use. As autonomous technology is increasingly at the center of contemporary military innovations, questions of (human) agency and responsibility in warfare have become even more pressing. As stressed by the United Nations Institute for Disarmament Research (UNIDIR), the concept of MHC may prove useful in the context of development and use of (semi-) autonomous weaponry.},

The existing research predominantly focuses on the role of either the features of social media and cloud computing in relation to the perceptions of decision makers or the internal capabilities of organization concerning new innovation adoption. By integrating multidisciplinary literature, we, instead, argues that both the perception- and capability-related factors could play an important role in the adoption of new ICT technology, such as SM\&PC. Therefore, we empirically investigated the decision maker's perception-related and SME's capability-related factors that may influence the adoption of SM\&PC in SMEs in Germany. We used quantitative research methods to examine the proposed hypotheses on a sample of 2,404 SMEs from 17 industrial sectors. The results demonstrate that the decisions of German SMEs to engage in social media and cloud computing are not only influenced by the perceptions of SME owners about the usefulness, security aspects, and the implementation costs of SM\&PC, but also by the internal capabilities of an SME, namely the innovativeness of an SME. The results and potential contributions of our research are discussed.},

Currently appointed Information and Communications Technology (ICT) used for coordination and communication is sometimes outdated and does not scale, while novel technologies have the potential to greatly improve disaster response efficiency. To allow adoption of these novel technologies, ICT system designers have to take into account the particular needs of DROs and characteristics of International Disaster Response (IDR). This work attempts to bring the humanitarian and ICT communities closer together. In this work, we analyze IDR-related documents and conduct expert interviews. Using open coding, we extract empirical insights and translate the peculiarities of DRO coordination and operation into tangible ICT design requirements. This information is based on interviews with active IDR staff as well as DRO guidelines and reports. Ultimately, the goal of this paper is to serve as a reference for future ICT research endeavors to support and increase the efficiency of IDR operations.},

abstract = {Social media is used during crises and disasters by state authorities and citizens to communicate and provide, gain and analyze information. Monitoring of platforms in such cases is both a well-established practice and a research area. The question, whether people are willing to renounce privacy in social media during critical incidents, or even allow surveillance in order to contribute to public security, remains unanswered. Our survey of 1,024 German inhabitants is the first empirical study on people's views on social media monitoring and surveillance in crisis management. We find the willingness to share data during an imminent threat depends mostly on the type of data: a majority (63\% and 67\%, respectively) would give access to addresses and telephone numbers, whereas the willingness to share content of chats or telephone calls is significantly lower (27\%). Our analysis reveals diverging opinions among participants and some effects of sociodemographic variables on the acceptance of invasions into privacy.},

Im Zuge dessen werden detaillierte Vereinbarungen bezüglich der bereitzustellenden betrieblichen Daten sowie der Verwendung der während der Dienstleistung erhobenen Messwerte getroffen. Im Rahmen des Projektes HyServ werden Servicekonzepte und Schnittstellen entwickelt, welche es den Akteuren erlauben, die Hoheit über die eigenen Daten zu behalten und dennoch kooperative Dienstleistungsverträge zu erstellen. Zu diesem Zweck werden dezentrale Strukturen mit kryptographisch gesichertem Austausch etabliert, welche als Infrastruktur für orchestrierte Micro-Services und Smart Contracts dienen.},

Although ICT plays an increasingly large role in crisis response and management, in-depth studies on crisis apps and similar technology in the context of an emergency have been missing. Based on responses by 1024 participants in Germany, we examine the diffusion, usage, perception and adoption of mobile crisis apps as well as required functions and improvements. We conclude that crisis apps are still a little-known form of disaster ICT, but have potential for enhancing communication, keeping users up to date and providing a more effective crisis management as supplement to other media channels dependent on different underlying infrastructures. However, they should be adaptable to user characteristics, consider privacy, allow communication and offer valuable information to raise awareness of potential disasters without creating an overload. Also, the familiarity with and trust in crisis apps should be addressed to maximize their beneficial impact on crisis communication and management. We discuss further implications as well as directions for future research with larger target groups and specific usage scenarios.},

The produced data is spread across several types of social media and can be used by different actors, such as emergency services or volunteer communities. There are already systems available that support the process of gathering, analysing and distributing information through social media. However, dependent on the goal of analysis, the analysis methods and available systems are limited based on technical or business-oriented restrictions. This paper presents the design of a cross-platform Social Media API, which was integrated and evaluated within multiple emergency scenarios. Based on the lessons learned, we outline the core challenges from the practical development and theoretical findings, focusing (1) cross-platform gathering and data management, (2) trustability and information quality, (3) tailorability and adjustable data operations, and (4) queries, performance, and technical development.},

Even in software engineering, the promotion of flow experience fosters effects such as positive affect, improved learning, and higher product loyalty in computer-aided environments. However, from a practice-based perspective it is not obvious how to design ICT to support flow experience. With this paper, we, therefore, contribute concrete design implications, paving the way for a good flow experience in ICT. This paper be-gins by examining the current state of flow research in the field of Human-Computer Interaction. We then go on to present a study comprising the development and evaluation of design options that aim to support flow in integrated development environments such as Eclipse, one of the most prominent open-source IDEs. The findings reveal practical implications on the use of four flow design options for software engineering and are integrated into a preliminary research framework.},

To counter these risks, besides implementing supportive technology, social media guidelines may help putting artefact and theoretical contributions into practical use for authorities and citizens.

This exploratory study investigates counter narrative campaigns with regard to their fight and prevention against terrorism in social media. Posts with strong emotions and a personal reference to affected individuals achieved the highest impact and most reactions from the target group. Furthermore, our results illustrate that the impact of a counter narrative campaign cannot be measured solely according to the reaction rate to their postings and that further analysis steps are therefore necessary for the final evaluation of the campaigns.},

To show the impact of cyberattacks on agriculture, we present a simulation of several attacks on a ZigBee-based wireless sensor network. We conduct a delay attack, an interference attack and three different routing attacks (sinkhole, blackhole and selective forwarding attack). Those attacks are simulated using NETA with the OMNET++ framework.

abstract = {Verification is one of the pillars of arms control and non-proliferation treaties as well as an important part of confidence building measures. It defines practical measures that enable treaty members to check the treaty compliance by observing, counting or moni-toring specific actions and their accordance with the respective rules. In contrast to his-torical examples of former military technologies, cyberspace features some unique char-acteristics making it hard to apply established measures. The chapter describes these peculiarities and assesses distinguishing problems compared to selected verification measures for nuclear, biological and chemicals weapons technology. Yet, cyberspace is a human-made domain and adjusting its technical setting, rules and principles may help to reduce the threat of ongoing militarisation. Offering some alternatives, the chapter elaborates on suitable and measurable parameters for this domain and presents potential-ly useful verification approaches.},

abstract = {On-site work of emergency service teams consists of highly cooperative tasks. Especially during distributed search and rescue tasks there is a constant mix of routinized and non-routinized activities. Within this paper we focus on the work practices of the German Red Cross Rescue Dog Units who deal with several uncertainties regarding the involved dogs, the fragility of the respective situations as well as issues of using technologies under enormous time pressure. Smart glasses provide possibilities for enhanced and hands-free interaction in various contexts and a number of approaches have already been applied, aiming at efficient use of the respective technological innovation in private and professional contexts. However, the collaborative potential of smart glasses in time-critical and uncertain situations is still unexplored. Our design case study examines how the on-site work of emergency service teams can be supported by smart glasses: Based on examining the work practices of the German Red Cross Rescue Dogs, we introduce ‘RescueGlass' as a coordinative concept, encompassing hands-free head-mounted display (HMD) application as well as a corresponding smartphone application. Finally, we describe the evaluation of its use in the field of emergency response and management. We show how current features such as ‘fog of war' or various sensors support the cooperative practices of dog handlers, and outline current technical limitations offering future research questions. Our paper provides an initial design probe using smart glasses to engage in the field of collaborative professional mobile tasks.},

More than 80\% of the participants agree that fake news poses a threat. 78\% see fake news as harming democracy. Even though about half of the respondents (48\%) have noticed fake news, most participants stated to have never liked, shared or commented on fake news. Regarding demographic factors, our findings support the view of younger and relatively educated people being more informed about fake news. Concerning ideological motives, the evaluation suggests left-wing or liberal respondents to be more critical of fake news},

While German and British participants' frequency of use of social media is medium and low, respectively, Italian and Dutch respondents use them relatively frequently. Our comparison of the four countries allows for an interpretation of divergent behavior across countries with respect to risk cultures as well as expanding the respective model to social media contexts. At the same time, our findings stress that across the four European countries participants assessed similar advantages like dissemination of information and barriers like false rumors with respect to use social media during emergencies. Distributed equally across nations, age and gender showed significant relationships with social media usage which, among other findings, suggests being helpful for effective implementation of management structures using new technologies.},

abstract = {With the increasing popularity of the smartphone, the number of people using it for financial transactions such as online shopping, online banking or mobile payment is also growing. Apps used in these contexts store sensitive and valuable data, creating a need for security measures. It has not yet been researched to what extent certain authentication mechanisms, which can be information-, biometric- as well as token-based, are suitable for individual apps and the respective data. The goal of this work is to assess how perceived security and estimated effort of using such mechanisms, as well as the degree to which app data is considered worth protecting, influence users' choices of appropriate measures to protect app categories. Therefore, we conducted a representative study (n=1024). On the one hand, our results show that a positive correlation between perceived security and effort exists for all investigated non-biometric authentication methods. On the other hand, the study sheds light on the differences between the investigated app categories and the users' choice of the appropriate security mechanisms for the particular category. In contrast to perceived security having a positive influence on a user's preference of mechanism, a relation can hardly be identified for effort. Moreover, app data sensitivity does not seem relevant for the users' choice of security mechanism.},

abstract = {The use of information technology (IT) in peace, conflict and security raises some questions, i.e. whether the use of IT can be limited exclusively to so-called advantageous purposes and applications and whether improper use can be prevented. This ambivalence is called a dual- use dilemma, meaning that objects, knowledge and technology can find both useful and harm- ful applications. Dual-use questions have been addressed in various disciplines, in particular in nuclear technology and the production of nuclear weapons, but also in chemistry and biology. In all these disciplines, dual-use topics in technical development and education have been discussed and addressed. Nevertheless, the importance of dual-use differs slightly, depending on the technology and its risks, as well as its distribution and application. Nuclear technology is less accessible than biotechnology, which in turn is less accessible than IT.},

Durch die vermehrte Koordination der Helfenden, auch unter Ein- satz sozialer Medien, kommt es zunehmend zu Konflikten zwi- schen den teilweise kollidierenden Erwartungshaltungen periodi- sierter Werte der eingebundenen Akteure. Die Entwicklung von Kollaborationswerkzeugen mit Hilfe der Methode des Value-Sen- sitive Designs kann bereits im Vorfeld solche Konflikte aufzeigen und gezielt verhindern oder moderieren. Dazu wurde in einer Fall- studie anhand des Hochwassers 2013 induktiv abgeleitet, welche Werte und Erwartungen die unterschiedlichen Stakeholder haben, und welche Konflikte sich daraus im Hinblick auf die Anforderun- gen ergeben. Diese Studie zeigt insbesondere die Konfliktpotenzi- ale für freiwillige HelferInnen in sozialen Medien in Bezug auf den Schutz der Privatsphäre und vor Diskriminierung auf und leistet damit einen Beitrag für die Konflikt-Optimierung und Akzeptanz- steigerung des Einsatzes sozialer Medien im Katastrophenschutz.},

Nomadic knowledge is enacted in a discontinuous pattern with a changing set of actors and further flows on a definedtrajectory. This knowledge is quite important but is required sporadically, so it has a varying level of importance for stakeholders at different instances of time. The limited interest of knowledge holders after the creation of knowledge makes the knowledge sharing processcomplex. Furthermore, new sets of actors overloaded with tasks often ignore the knowledge sharing aspect due to the urgency of tasks at hand. Using a long-term field study we describe a particular practice that is not well supported technologically. The objective of this paper is to outline the concept of nomadic knowledge and associated implications, so that respective practices can be supported by the knowledge management community with appropriate technology.},

Thus, public spaces and buildings will be equipped with more interconnected input and output modalities. This ongoing technolo- gization of public spaces creates opportunities for making everyone's life more secure, while at the same time everyone's personal privacy is endangered. So how is this balancing act tackled and dealt with right now? What fears do citizens have regarding their security as well as their privacy? This paper provides first insights into the topic privacy in smart cities regarding that smart cities need data which can be provided by and of people. The paper raises the question if collecting people's data, and thus enabling smart cities, is ethical and if not, how it can be assured to be ethical.},

Few studies have focused on European citizens' perceptions, and just one has deployed a representative sample to examine this. This article presents the results of one of the first representative studies on this topic conducted in the United Kingdom. The study shows that around a third (34\%) have used social media during an emergency and that such use is more widespread among younger people. In contrast, the main reasons for not using social media in an emergency include technological concerns and that the trustworthiness of social media content is doubtful. However, there is a growing trend towards increased use. The article deduces and explores implications of these findings, including problems potentially arising with more citizens sharing information on social media during emergencies and expecting a response.},

Given the recent increase of natural disasters and man-made crises and emergencies, it seems an important economic goal to ascertain that SMEs are capable of maintaining their work, revenue and profit at an acceptable level. According to ISO 22301, business continuity management (BCM) is a holistic management process which identifies potential threats and their impact to an organization and serves as a framework to increase organizational resilience and response capabilities. Prior research identified that BCM is under-represented in SMEs and that their security level is partially in an uneconomical range. This article presents the analysis of interviews with 19 independent micro enterprises highlighting findings on their low crisis awareness, varying technical dependency, existing action strategies and communication strategies and proposing a categorization of micro enterprises as preventive technicians, data-intensive chains or pragmatic jumpers.},

In such situations, not only do citizens demand information about the damage and safe behaviour, but emergency services also require high quality information to improve situational awareness. For this purpose, there are currently two kinds of apps available: Gen- eral-purpose apps, such as Facebook Safety Check or Twitter Alerts, already integrate safety features. Specific crisis apps, such as KATWARN in Germany or FEMA in the US, provide information on how to behave before, during and after emergencies, and capabilities for reporting incidents or receiving disaster warnings. In this paper, we analyse authorities' and citizens' information demands and features of crisis apps. Moreover, we present the concept, implementation and evaluation of a crisis app for incident reporting and bidirectional communication between authorities and citizens. Using the app, citizens may (1) report incidents by providing a category, description, location and multimedia files and (2) receive broadcasts and responses from authorities. Finally, we outline features, requirements and contextual factors for incident reporting and bidirectional communication via mobile app.},

abstract = {In 2004, Information Systems for Crisis Response and Management (ISCRAM) was a new area of research. Pio- neering researchers from different continents and disciplines found fellowship at the first ISCRAM workshop. Around the same time, the use of social media in crises was first recognized in academia. In 2018, the 15 th IS- CRAM conference will take place, which gives us the possibility to look back on what has already been achieved with regard to IT support in crises using social media. With this article, we examine trends and developments with a specific focus on social media. We analyzed all papers published at previous ISCRAMs (n=1339). Our analysis shows that various platforms, the use of language and coverage of different types of disasters follow certain trends – most noticeably a dominance of Twitter, English and crises with large impacts such as hurricanes or earthquakes can be seen.},

abstract = {The Internet has changed consumer behavior, having an impact on local retail. At the same time, the number of smartphone users is continuously increasing, making mobile applications more and more important. By using Bluetooth beacons – small radio transmitters which can be placed everywhere and processed by an according app – shopping can be facilitated and made more enjoyable. Even though some supermarkets, especially in the USA, are already using beacons, their use is not common and less researched in Germany. Pilot projects only refer to usage data and reaction times while customers are rarely asked for their opinion. This work analyzes potentials of usage and customer acceptance of concepts based on beacons in retail via an online consumer survey, the conception of an app as well as a subsequent qualitative evaluation. As a starting point for our concept development and app implementation, the previous online survey of 203 participants emphasizes the importance of user-friendly settings as well as costumers' interest in informative communica-tion. Throughout all steps of our design case study, concerns for data privacy linked with interest in transparency were apparent and included, respectively. The field experiment stresses users' perceptions of potentially useful functions, and highlights design-related aspects for improvement, offering useful implications for future design of shopping apps.},

Solche Technologien müssen verschiedene Anforderungen erfüllen und können ebenfalls zur Resilienz beitragen. Unter Resilienz durch Kooperation verstehen wir die Fähigkeit, Krisen durch die Anpassungsfähigkeit an geänderte Realitäten ohne nachhaltigen Schaden mithilfe von Kooperation zu überstehen. Während das Konzept der Resilienz in den Ingenieurwissenschaften vornehmlich die Verfügbarkeit technischer Systeme fokussiert, betrachten wir Resilienz als soziotechnisches Konstrukt, unter expliziter Betrachtung der beteiligten Akteure. Basierend auf Grundlagen zu Kooperationstechnologien zeigt unser Kapitel anhand von praktischen exemplarisch umgesetzten Kooperationstechnologien (soziales Netzwerk, GIS-System, Smartphone Apps, Facebook App und Social Media Analytics-Plattform), wie Kooperation unterstützt wird und zu kooperativer Resilienz beitragen kann.},

Unsere repräsentative Untersuchung von Einstellungen der Bevölkerung in Deutschland gegenüber der Nutzung sozialer Medien in Notsituationen stellt die erste ihrer Art dar. Dabei zeigt sich, dass ungefähr die Hälfte der Befragten (44 \%) bereits in Notsituationen zum Zwecke des Teilens und / oder Herausfindens von Informationen auf soziale Medien zurückgegriffen hat. Zudem werden falsche Gerüchte in sozialen Medien mehrheitlich (74 \%) als Bedrohung empfunden.

abstract = {Flow-Erleben beschreibt das „reflexionsfreie, gänzliche Aufgehen in einer glatt laufenden Tätigkeit, die man trotz hoher Beanspruchung noch unter Kontrolle hat“. Dabei zeigt die bestehende Literatur vielversprechende Effekte der Flow-Theorie auf, etwa positiver Affekt, verbessertes Lernen, Mitarbeiterproduktivität und Kundenloyalität, die einen Mehrwert in der Mensch-Computer-Interaktion und der Gestaltung interaktiver Systeme darstellen. Die Betrachtung der theoretischen Grundlagen zeigt, dass Flow ein komponentenreiches Konstrukt ist, welches kontextsensitiv erforscht werden muss: Die Beschaffenheit der gegenwärtigen Aufgabe und des interaktiven Systems, sowie demografische, individuelle und situative Faktoren beeinflussen das Flow-erleben. Zur Messung des Flow-erlebens wurden eine Reihe unterschiedlicher Messmethoden entwickelt, welche die gegenwärtige Erfahrung, etwa der FQ oder die esM, oder eine vergangene Erfahrung im Nachgang, etwa komponentenbasierte Fragebogen und qualitative Methoden, erfassen. In der Gestaltung interaktiver Systeme im Sinne der MCI wird einerseits die Betrachtung pragmatischer Qualitätskriterien (Effizienz, Durchschaubarkeit, Verlässlichkeit) der Usability und hedonistischer Qualitätskriterien (Attraktivität, Neuheit, Stimulation) der User Experience angestrebt. Andererseits untersucht ein separater Forschungsstrang die Relevanz der Flow-Theorie für die MCI. Während der Einfluss theoretischer Konstrukte des Flow-erlebens bereits deutlich untersucht wurde, fehlt die systematische Verknüpfung zu konkreten Designanforderungen zur Unterstützung des Flow-erlebens in interaktiven Systemen. Damit die Potenziale der Flow-Theorie in der Gestaltung interaktiver Systeme bestmöglich berücksichtigt werden können, sind vor allem vier Herausforderungen in der Forschung und Praxis zu adressieren: 1. Definition der theoretischen Kontextfaktoren: Wie kann die Flow-Theorie in der Mensch-Computer-Interaktion ganzheitlich bestimmt werden? 2. Operationalisierung der Flow-Theorie: Wie können Bedingungen, Erleben und Auswirkungen des Flow-erlebens genau und systematisch gemessen werden? 3. Integration in die Mensch-Computer-Interaktion: In welchem exakten Zusammenhang stehen die Konzepte Flow, Usability und User Experience? 4. Ableitung praktischer Designanforderungen: Wie können praktische Anforderungen zum Design des Flow-erlebens in interaktiven Systemen abgeleitet werden? Dieser Beitrag hat dazu die theoretischen Grundlagen des Flow-erlebens, bestehende Methoden und Metriken sowie verwandte Konzepte der MCI eingeleitet und diskutiert, um einerseits die systematische Erforschung der Flow-Theorie in der MCI und andererseits die Ableitung praktischer Design-Anforderungen zu motivieren.},

abstract = {Abstract Although emergency services have already recognized the importance of citizen-initiated activities during disasters, still questions with regard to the coordination of spontaneous volunteers and their activities arise. Within our article, we will present a technological approach based on public displays which aims to foster situated crowdsourcing between affected citizens, spontaneous volunteers as well as official emergency services. We will address the research question: How can the situated tasks performed by spontaneous volunteers be supported by the use of public displays during disasters? First we will present the current state of the art with regard to the coordination practices of spontaneous volunteers and emergency services within disaster situations as well as related problems, potentials and specifics of situated crowdsourcing and public displays. To gain insight into actual coordination practices, we conducted an empirical study with 18 different stakeholders involved in disaster management. Based on the literature review and our empirical study, we have derived a technical concept that supports the task and activity management of spontaneous volunteers as well as the coordination both of the demands of affected people and the offers from spontaneous volunteers. We have implemented our concept as the public display application ‘City-Share', which provides a robust communication infrastructure and encompasses situated crowdsourcing mechanisms for managing offers and demands of activities on-the-ground. Based on its evaluation with several users, we will discuss our findings with regard to the assignment of tasks on-the-ground and situated crowdsourcing during emergencies. We outline that City-Share can improve a community's disaster resilience, especially when focusing on the kind of collaborative resilience emerging between official stakeholders and spontaneous volunteers or affected citizens at a local level.},

abstract = {In recent years, social media have increased the resources that individuals and organizations are able to mobilize for the development of socially innovative practices. In this article, we engage with a naturally occurring development in a Trentinian neighbourhood to examine the cooperative interactions amongst members of a local community. The first author and local residents of the neighbourhood participated in online discussions, decision making, and physical activities that led to material changes in the area. The interventions are motivated by and based on the concept of Social Street that combines online interactions in a closed Facebook group with face-to-face meetings seeking to practically engage the collective in accomplishing certain immediate or ongoing needs. Over the course of two years, we studied this local instantiation of Social Street in Trento, Italy by way of an action-oriented (digital) ethnography. Through this work, we demonstrate how urban neighbourhoods might benefit from hybrid forms of community engagement that are enacted through a constant back and forth between online and face-to-face interactions. We further argue that the infrastructuring of local urban collectives should follow strategies that pay attention to the multiple issues in urban neighbourhoods and people's attachments to them. Overall, the paper reflects upon the challenges and configurations of participation that this form of community-work entails.},

Our study highlights, for example, that around half (45\%) of people have used social media during an emergency to share and / or look for information. In contrast, false rumours on social media (74\%) are perceived as a threat. Moreover, only a minority of people have downloaded a smartphone app for emergencies (16\%), with the most popular ones' weather and first aid apps.},

abstract = {Crises, such as thunderstorms and an increasing number of (recognised) terroristic attacks in 2015, 2016, and 2017, do not only lead to extensive monetary damage, but also threaten human lives and influence citizens' perceptions of safety and security. In such situations, the population demands information about the damage and safe behaviour. Although some apps are available to provide this information, the number of users seems relatively low. Focussing on Germany, this study aims to research (1) the distribution of crisis apps in the population, (2) the kinds of crisis apps currently used, as well as (3) needed core functionalities of warning apps. This multi-method study analyses crisis apps by investigating their utilisation quantitatively in a snowball-based survey in Europe (n=1,034) and in a representative survey in Germany (n=1,369). Based on this, the German warning apps Katwarn and NINA and the US-American app FEMA are evaluated qualitatively (n=22). The results revealed requirements which informed the implementation of a warning app prototype. The prototype combines the identified advantages of the apps evaluated in the study, containing warnings and all-clear, recommendations for action, functions to contact friends and helpers. The contributions of this work are findings on the distribution of crisis apps in Europe and Germany (both 16\%), the kinds of crisis apps used (mostly weather and warning apps), and empirically based requirements for warning apps which can be integrated in further developments of existing apps and a prototype for such an app.},

The social big data, generated by users, is partially also used as a source for situation assessment, e.g. to receive pictures or to assess the general mood. However, the information's believability is hard to control and can deceive. Rumors, fake news and social bots are phenomenons that challenge the easy consumption of social media. To address this, our paper explores the believability of content in social media. Based on foundations of information quality we conducted a literature study to derive a three-level model for assessing believability. It summarizes existing assessment approaches, assessment criteria and related measures. On this basis, we describe several steps towards the development of an assessment approach that works across different types of social media.},

Based on the technological advances with mobile and ubiquitous computing, the use of social media is getting more and more usual in daily life as well as in extraordinary situations, such as crises. Not surprisingly, this increasing use is one reason why data on the internet is also developing that fast. Currently, more than 3 billion people use the internet and the majority is also registered with social media services such as Facebook or Twitter. While processing this kind of data by the majority of non-technical users, concepts of End-User Development (EUD) are important. This chapter researches how concepts of EUD might be applied to handle social big data. Based on foundations and an empirical pre-study, we explore how EUD can support the gathering and assessment process of social media. In this context, we investigate how end-users can articulate their personal quality criteria appropriately and how the selection of relevant data can be supported by EUD approaches. We present a tailorable social media gathering service and quality assessment service for social media content, which has been implemented and integrated into an application for both volunteers and the emergency services.},

abstract = {Social media and instant messaging services are nowadays considered as important communication infrastructures on which people rely on. However, the exchange of content during breakdowns of the underlying technical infrastructures, which sometimes happens based on environmental occurrences, is challenging. Hence, with this paper, we examine the resilience of social media during breakdowns. We discuss communication options and examine ad-hoc functionality for the exchange of social media data between different actors in such cases. To address this, we have developed a concept, which makes use of mobile ad-hoc networks (MANETs) for the spontaneous exchange of information with smartphones. We implemented our concept as the mobile application Social Offline Map (SOMAP) and evaluated it within two iterations (1.0 and 2.0). Finally, we discuss our contribution within the context of related work and the limitations of our approach.},

However, larger quantitative studies with significant results on attitudes, needs and future plans of citizens in such events are not available - especially such of a comparative nature related to emergency services. As part of the EU project ‘EmerGent' this article presents the findings of a survey of 1034 citizens across 30 European countries conducted between February and June 2015 to explore citizens' attitudes towards the use of social media for private purposes and in emergency situations. The article briefly compares these findings with a second survey conducted with 761 emergency service staff across 32 European countries from September to December 2014. The aim of the overall study is to discuss citizens' attitudes towards social media in emergencies in order to derive challenges and opportunities for social resilience.},

abstract = {For almost 15 years, social media have been regularly used during emergencies. One of the most recent, and instructive, examples of its widespread use during a large scale scenario in Europe were the 2013 European floods. Public reporting during the event indicated, and our analysis confirms, that Twitter, Facebook (FB), Google Maps and other services were frequently used by affected citizen and volunteers to coordinate help activities among themselves. We conducted a qualitative analysis of selected emergent volunteer communities in Germany on FB and Twitter among others, and subsequently conducted interviews with FB group founders and activists. Our aim was to analyze the use of social media during this particular event, especially by digital volunteers. Our study illustrates the relevance of social media for German citizens in cases of disaster, focusing especially on the role of the moderator. Our specific emphasis was the embedding of social media in the organizing work done by said volunteers, emphasizing both the patterns of social media use and the challenges that result. We show that different social media were used in different ways: Twitter was used in the main for status updates while FB-pages were mostly intended to provide an overview. FB-groups also coordinated a multitude of activities.},

abstract = {In recent years, citizens' movements such as the Arab Spring or Euromaidan protests have clearly shown that, whenever affected — whether negatively or positively — by the state and government decisions, citizens act to deal with the shared issues. Groups of people who organize themselves to address (mainly political) issues were defined as a `public' by the philosopher John Dewey. He believed it is necessary to improve communication to create a `Great Community' as a cohesive group of a public. Although information and communication technologies (ICT) lead to ambivalent effects on pursuing this goal and often distract the mass of people from discussing these issues, we argue that nowadays ICT can improve communication and has the potential to foster the detection of issues and therefore promote the (trans-)formation of a public into an issue-based community. As our foundation we took a literature study covering the formation of publics and their potential to evolve into communities, as well as their interplay with technology. This formed the basis for the development of our operational model that `follows the issues' for capturing the (trans-)formation of a public. Based on our model, we outline different perspectives on detecting shared issues as early indicators for publics based on ICT and derive implications for researching this process from a practical perspective.},

Much of this research is based on Twitter data, due to the ease of access of this (mainly public) data, compared to (more closed) data, such as Facebook or Google+. Based on the experience gained from a research project on social media in emergencies and our task to collect social media data sets for other partners, we present the design and evaluation of a graphical user interface that supports those stakeholders (such as emergency services or researchers) that are interested in creating social media datasets for further crisis management research. We do not specifically focus on the analysis of social media data. Rather we aim to support the gathering process and how actors without sophisticated technical skills can be supported to get what they want and especially need: relevant social media data. Within this article, we present a practice-oriented approach and implications for designing tools that support the collection of social media data as well as future work.},

People are using social media to a greater extent, also in emergency situations. During disasters throughout the world, such as the 2010 Haiti earthquake, the 2013 European floods, or the terror attacks 2015 in Paris and 2016 in Brussels, this has been illustrated again. Often information about disasters even finds its way faster to social media than it reaches regular news companies and emergency services. However, approaches for processing and analyzing the vast quantities of data produced have even more potential. Yet many emergency services still have not found a way to put this potential to an effective use. Within our project EmerGent we are developing a system to process and analyse information from social media particularly tailored for the specific needs of emergency services. The aim is to transform the high volume of noisy data into a low volume of rich content that is useful to emergency personnel. In the first part of this paper we present our approach from a user interface perspective. The second part deals with the evaluation of the approach and the derivation of future potentials of the approach.},

Therefore it first investigates the perception and information demands of citizens and communication infrastructures in different scenarios. Furthermore, it analyzes communication infrastructures and their availability in different scenarios. Finally it proposes ‘BlaCom', an ICT-based concept for blackout communication, which addresses the time span between the occurrence of the energy blackout and the possible overload of the mobile phone network. It combines general information with location-specific and setting-specific information, was implemented as a prototype smartphone application and evaluated with 12 potential end users.},

abstract = {People all over the world are regularly affected by disasters and emergencies. Besides official emergency services, ordinary citizens are getting increasingly involved in crisis response work. They are usually present on-site at the place of incident and use social media to share information about the event. For emergency services, the large amount of citizen-generated content in social media, however, means that finding high-quality information is similar to “finding a needle in a haystack”. This article presents an approach to how a dynamic and subjective quality assessment of citizen-generated content could support the work of emergency services. First, we present results of our empirical study concerning the usage of citizen-generated content by emergency services. Based on our literature review and empirical study, we derive design guidelines and describe a concept for dynamic quality measurement that is implemented as a service-oriented web-application “Social Haystack.” Finally, we outline findings of its evaluation and implications thereof.},

These activities can be found in (physical) groups of affected people, but also within (digital) social media communities. There is an evident need, however, for a clearer picture of what exactly is going on to be available for use by the official emergency services: to enlist them, to keep them safe, to support their efforts and to avoid need-less duplications or conflicts. Aligning emergency services and volunteer activities is, then, crucial. In this paper we present a mobile crowd sensing based concept, which was designed as well as implemented as the application CrowdMonitor and facilitates the detection of physical and digital activities and the assignment of specific tasks to citizens. Finally, we outline the findings of its evaluation.},

The concept was implemented based on a Microsoft PixelSense and evaluated with 14 participants. The results reveal the impact of subjectivity of the participants, their positioning around the table as well as the uniqueness of social media posts on the collaborative situation assessment with multi-touch tables},

However, approaches for processing and analyzing the vast quantities of data produced currently lag far behind. In this paper we discuss important steps, and the associated challenges, for processing and analyzing social media in emergencies. In our research project EmerGent, a huge volume of low-quality messages will be continuously gathered from a variety of social media services such as Facebook or Twitter. Our aim is to design a software system that will process and analyze social media data, transforming the high volume of noisy data into a low volume of rich content that is useful to emergency personnel. Therefore, suitable techniques are needed to extract and condense key information from raw social media data, allowing detection of relevant events and generation of alerts pertinent to emergency personnel.},

However its analysis by emergency services still bears unaddressed challenges and the majority of studies focus on the use of social media in the USA. In this paper German tweets of the European Flood 2013 are therefore captured and analyzed using descriptive statistics, qualitative data coding, and computational algorithms. Our work illustrates that this event provided sufficient German traffic and geo-locations as well as enough original data (not derivative). However, up-to-date Named Entity Recognizer (NER) with German classifier could not recognize German rivers and highways satisfactorily. Furthermore our analysis revealed pragmatic (linguistic) barriers resulting from irony, wordplay, and ambiguity, as well as in retweet-behavior. To ease the analysis of data we suggest a retweet ratio, which is illustrated to be higher with important tweets and may help selecting tweets for mining. We argue that existing software has to be adapted and improved for German language characteristics, also to detect markedness, seriousness and truth},

This paper examines the use of social media during the European Floods of 2013 and proposes a novel cross-social-media application for volunteers. Besides comprehensive analysis of volunteer communities, interviews were conducted with "digital volunteers" such as Facebook moderators of disaster-related groups. Based on the challenges identified, we designed and implemented the cross-social-media application "XHELP", which allows information to be both, acquired and distributed cross-media and cross-channel. The evaluation with 20 users leads to further design requirements for applications aiming to support volunteer moderators during disasters.},

abstract = {Emergency or crisis management, as is well-attested, is a complex management problem. A variety of agencies need to collaborate and coordinate in real-time and with an urgency that is not always present in other domains. It follows that accurate information of varying kinds (e.g. geographical and weather conditions; available skills and expertises; state-of-play; current dispositions and deployments) needs to be made available in a timely fashion to the organizations and individuals who need it. By definition, this information will come from a number of sources both within and across organizations. Large-scale events in particular necessitate collaboration with other organizations. Of course, plans and processes exist to deal with such events but the number of dynamically changing factors as well as the high number of heterogeneous organizations and the high degree of interdependency involved make it impossible to plan for all contingencies. A degree of ongoing improvisation, which typically occurs by means of a variety of information and expertise sharing practices, therefore becomes necessary. This, however, faces many challenges, such as different organizational cultures, distinct individual and coordinative work practices and discrete information systems. Our work entails an examination of the practices of information and expertise sharing, and the obstacles to it, in inter-organizational crisis management. We conceive of this as a design case study, such that we examine a problem area and its scope; conduct detailed enquiries into practice in that area, and provide design recommendations for implementation and evaluation. First, we will present the results of an empirical study of collaboration practices between organizations and public authorities with security responsibilities such as the police, fire departments, public administration and electricity network operators, mainly in scenarios of medium to large power outages in Germany. Based on these results, we will describe a concept, which was designed, implemented and evaluated as a system prototype, in two iterations. While the first iteration focuses on situation assessment, the second iteration also includes inter-organizational collaboration functionalities. Based on the findings of our evaluations with practitioners, we will discuss how to support collaboration with a particular focus on information and expertise sharing.},

First, we present the results of an empirical study about informal work and mobile collaboration practices of emergency services. Then we describe the concept of a mobile geo-collaboration system that addresses the aspects detected in the empirical study and that was implemented as an Android application using web sockets, a technology enabling full-duplex ad hoc communication.

This paper analyzes these limitations (in June 2014) for the most important social media. The selection of social media is based on the Monthly Active Users (MAU), which counts unique users over 30 days.

Some necessary information is integrated into control centre's IT (weather, availability of electricity, gauge information, etc.), but almost every decision needs to be based on very specific information of the current crisis situation. Due to the unpredictable nature of a crisis, gathering this kind of information requires much improvisation and articulation work which we aim to support. We present a study on how different emergency response organisations communicate with teams on-site to generate necessary information for the coordinating instances, and we described, implemented and evaluated an interaction concept as well as a prototype to support this communication by a semi-structured request-and-report system based on Android devices. We learned that (1) the accuracy of request and reports can be improved by using an appropriate metadata structure in addition to creating multimedia-based information content, (2) requirements of trusted and fast information need to be respected in support concepts although they may even be contradictory, and (3) the coordination strategy of the emergency response organisation also shapes the way this interaction needs to be designed.},

With our research we consider real and virtual volunteers in order to detect conditions for cooperation among those citizen groups through social media. Therefore we analysed the usage of Twitter during a tornado crisis to look for role patterns and aspects that helped volunteer groups in the virtual to emerge, and matched the data with an interview study on experiences, attitudes, concerns and potentials professional emergency services recounted in the emergence of volunteer groups in the real. While virtual groups seem to easily form and collaborate, the engagement of real volunteers is decreasing according to the perception of professionals. We discuss the dynamics in both tendencies and suggest design implications (use of existing social networks, promotion and awareness, connection among volunteers, connection to emergency services and systems) to support both types of volunteer groups, which lead to a software prototype.},

abstract = {Crisis communication during power outages poses several challenges. Frist, the causes of power outages are often events such as severe weather, which also lead to complications. Second, power outages themselves lead to limitations in everyday life. Third, communication infrastructures, that are necessary for crisis communication, are often affected. This work focuses on the communication of the organizations responsible for recovery work (emergency services, public administration, energy network operators) to the public affected by the power outage. Therefore this paper investigates the perception and the information demands of citizens and communication infrastructures in different scenarios. Taking the users' needs into consideration, an Information and Communication Technology (ICT) based concept for crisis communication, which combines general information with location-specific and setting-specific information was implemented as a prototype smartphone application and evaluated with 12 potential end users. ICT-based concepts can gain acceptance, however they should be understood as supplemental for some target groups and in some scenarios.},

abstract = {The electricity network is one of the most important infrastructures in modern industrialized societies. In the case of power outages, the society becomes aware of their dependence on electricity and organizations responsible for recovery work need precise information about the location and the type of the damage, which are usually not available. Unmanned Aerial Systems (UAS), commonly known as drones, are aircrafts without a human pilot on board and may help to collect this information. While many technical approaches for UAS exist, a systematic process model for using UAS in emergencies based on the organizations needs is still missing. Based on the presentation of current types of UAS, approaches of using UAS and workshops with organizations responsible for recovery work (police and fire department, public administration, power supplier) this paper presents a process model for UAS in emergencies, especially power outages, which takes both theoretical findings and human experiences into consideration.},

Sie zeigen auch, welche wichtige Rolle die Kooperation und Zusammenarbeit zwischen allen Beteiligten der Bewältigungs- und Wiederherstellungsarbeit spielt. Die Erfahrungen aus diesen Ausfällen legen nahe, dass Stromnetzbetreiber, Feuerwehr, Polizei, Behörden und Bürger einer Vielzahl von unterschiedlichen Herausforderungen in der interorganisationalen Kommunikation und innerhalb von Informations- und Koordinierungsprozessen gegenüberstehen. Ziel des Forschungsprojekts „InfoStrom“, welches vom Bundesministerium für Bildung und Forschung seit 2010 und bis Ende 2013 gefördert wird, ist die Entwicklung von Konzepten, um diese Zusammenarbeit zu unterstützten und letztlich zu verbessern. In diesem Beitrag werden potentielle Fragen und zukünftige Themen und erzielte Ergebnisse dargestellt, die sich auf die benutzerzentrierte Technologieentwicklung im Krisenmanagement und auf domain-spezifische Probleme, wie die Verbesserung der Integration von Bürgern in das Krisenmanagement, den Umgang mit Informationsunsicherheiten oder die Unterstützung des interorganisationalen Lernens, beziehen.},

The creation, management, and adaptation of the process models require typically modeling-experts. While these actors are knowledgeable in formalizing and operationalizing processes end-users who do not necessarily possess sophisticated modeling skills know typically local practices and framing conditions best. In this paper, we present an approach to support users in articulating their needs and to involve them into the (re-)design of process specifications. We explore how end-users reflect upon and articulate about business processes. Based on results of a qualitative study, we present a new, paper-based interaction technique, which enables users with little skills to model processes. The resulting process specifications can be transferred either in paper or in digital form into traditional modeling systems for further elaboration.},

In these cases, information technology should not just automate planned and structured decisions, but support improvisational practice. In this contribution we present an empirical study about the improvisation work in scenarios of medium to large power outages in Germany. Our focus is on inter-organizational cooperation practices, thus we examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material allows to describe reasons and conditions for improvisation. Our resulting recommendations address the support of aggregation and visualization of information, a necessary individualization of information compositions, options for collaborative situation assessment, requirements for informal and formal communication, and accessibility of information resources.},

abstract = {To assess current situation properly is crucial for effective decision-making in crisis management. However, gathering accurate information from incidence sites and providing appropriate support for assessment practices faces several challenges. The unique information demands of each crisis situation, the information availability or inter-organizational problems and obstacles to information exchange are important factors that need to be considered in designing ICT. In this contribution we present results from an empirical study about decision-making practices in scenarios of medium to large power outages in Germany. We focused on the needs and practices on information exchange at the level of inter-organizational cooperation. We examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material reflects particularly conditions and challenges in current situation assessment practices, and we were able to derive some design requirements for an inter-organizational situation assessment client (ISAC) as a complementary tool for the crisis management infrastructures the individual organizations have already build for their own areas of responsibility: Support for the aggregation and visualization of information, for the individualization of information compositions, for a collaborative situation assessment and for appropriate structures for sharing and accessing information resources.},

Our work intends to show how so-called Emergent Groups, which arise as a result of crises, consist of private citizens and are not yet institutionalized organizations, can be supported by Social Media. At first, our literature review's objective is to define the term ‘Emergent Group' and to outline their usage of Social Media as well as software-based requirements and suitable concepts to support such groups. A following quantitative and qualitative empirical analysis of a tornado crisis in the USA enables a closer look at especially virtual working Emergent Groups. Building on our literature review and empirical analysis, we discuss implications, derive further requirements and present a concept for the design of appropriate Social Software. We finally conclude by giving some potential research issues.},

After defining the term ‘social software' we will outline the state-of-the-art about its use in crisis management. Drawing from this, we will present two case studies where we have examined the use of social software in 2010: first during the disruption of air travel caused by the eruptions of the volcano Eyjafjallajökull in Iceland and second during the mass panic at the Love Parade music festival in Germany. Based on both previous work and case studies we will discuss potentials and weaknesses and propose a classification matrix for different types of cooperation as a step towards a systematization of social software use in crisis situations.},
