TY - JOUR A1 - Aa, Han van der A1 - Rebmann, Adrian A1 - Leopold, Henrik T1 - Natural language-based detection of semantic execution anomalies in event logs JF - Information systems : IS ; an international journal ; data bases N2 - Anomaly detection in process mining aims to recognize outlying or unexpected behavior in event logs for purposes such as the removal of noise and identification of conformance violations. Existing techniques for this task are primarily frequency-based, arguing that behavior is anomalous because it is uncommon. However, such techniques ignore the semantics of recorded events and, therefore, do not take the meaning of potential anomalies into consideration. In this work, we overcome this caveat and focus on the detection of anomalies from a semantic perspective, arguing that anomalies can be recognized when process behavior does not make sense. To achieve this, we propose an approach that exploits the natural language associated with events. Our key idea is to detect anomalous process behavior by identifying semantically inconsistent execution patterns. To detect such patterns, we first automatically extract business objects and actions from the textual labels of events. We then compare these against a process-independent knowledge base. By populating this knowledge base with patterns from various kinds of resources, our approach can be used in a range of contexts and domains. We demonstrate the capability of our approach to successfully detect semantic execution anomalies through an evaluation based on a set of real-world and synthetic event logs and show the complementary nature of semantics-based anomaly detection to existing frequency-based techniques.

To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.

We attempt to address this gap by proposing a conceptual model of the BDAC - Innovation relationship using dynamic capability theory. The work expands on BDAC business value research and extends the nominal research done on BDAC – innovation. We focus on BDAC's relationship with different innovation objects, namely product, business process, and business model innovation, impacting all value chain activities. The insights gained will stimulate academic and practitioner interest in explicating strategic value generated from BDAC and serve as a framework for future research on the subject Y1 - 2021 UR - https://aisel.aisnet.org/pacis2021/79 SN - 978-1-7336325-7-7 IS - 473 PB - AIS Electronic Library (AISeL) CY - [Erscheinungsort nicht ermittelbar] ER - TY - THES A1 - Abromeit, Wolfgang T1 - Vertragsgestaltung bei komplexen Verträgen des Staates mit Privaten T2 - Schriften zum öffentlichen Recht N2 - Vertragsgestaltung ist ein praktisch sehr relevantes Thema, das wegen der Justizorientierung in der Wissenschaft noch weitgehend stiefmütterlich behandelt wird. In dieser Untersuchung wird, zumindest für die besonders delikate Konstellation bei komplexen Kooperationen des Staats mit Privaten (ÖPP/PPP), Abhilfe geschaffen. Dabei gründet die Analyse auf einer fundierten Typisierung und Charakterisierung der Probleme solcher Projekte. Den theoretischen Rahmen liefert eine effizienzorientierte Studie institutionenökonomischer Ansätze, namentlich der Transaktionskostentheorie und der Prinzipal-Agenten-Theorie, rückversichert über die praxisorientierten Grundregeln der vertraglichen Risikoverteilung. So gelingt es praktische Formulierungsvorschläge für Standardprobleme der Vertragsgestaltung, wie Leistungsbestimmungen, Anpassungsmechanismen, Konfliktbeilegungsregeln, Informationsmechanismen und Kündigungsregeln zu finden.

We focus on the use of information and communication technology (ICT) as a key means of alleviating these disruptions and promoting social inclusion. As social disruptions typically lead to frustration and fragmentation, it is essential to ensure the social inclusion of individuals and societies during such times. In the context of the social inclusion of refugees, we focus on the Syrian refugees who arrived in Germany as of 2015, as they form a large and coherent refugee community. In particular, we address the role of ICTs in refugees’ social inclusion and investigate how different ICTs (especially smartphones and social networks) can foster refugees’ integration and social inclusion. In the context of the COVID-19 pandemic, we focus on the widespread unconventional working model of work from home (WFH). Our research here centers on the main constructs of WFH and the key differences in WFH experiences based on personal characteristics such as gender and parental status. We reveal novel insights through four well-established research methods: literature review, mixed methods, qualitative method, and quantitative method. The results of our research have been published in the form of eight articles in major information systems venues and journals. Key results from the refugee research stream include the following: Smartphones represent a central component of refugee ICT use; refugees view ICT as a source of information and power; the social connectedness of refugees is strongly correlated with their Internet use; refugees are not relying solely on traditional methods to learn the German language or pursue further education; the ability to use smartphones anytime and anywhere gives refugees an empowering feeling of global connectedness; and ICTs empower refugees on three levels (community participation, sense of control, and self-efficacy). Key insights from the COVID-19 WFH stream include: Gender and the presence of children under the age of 18 affect workers’ control over their time, technology usefulness, and WFH conflicts, while not affecting their WFH attitudes; and both personal and technology-related factors affect an individual’s attitude toward WFH and their productivity. Further insights are being gathered at the time of submitting this thesis. This thesis contributes to the discussion within the information systems community regarding how to use different ICT solutions to promote the social inclusion of refugees in their new communities and foster an inclusive society. It also adds to the growing body of research on COVID-19, in particular on the sudden workplace transformation to WFH. The insights gathered in this thesis reveal theoretical implications and future opportunities for research in the field of information systems, practical implications for relevant stakeholders, and social implications related to the refugee crisis and the COVID-19 pandemic that must be addressed. N2 - Diese Dissertation beschäftigt sich mit zwei gesellschaftlichen Verwerfungen: den Flüchtlingswellen in Deutschland und der COVID-19-Pandemie. Dabei konzentrieren wir uns auf den Einsatz von Informations- und Kommunikationstechnologie (IKT) als eines der wichtigsten Mittel, um diese Verwerfungen zu mildern/abzufangen und soziale Eingliederung zu fördern. Soziale Verwerfungen führen in der Regel unter anderem zu Frustration und Fragmentierung. Daher ist es essenziell, die soziale Beteiligung von Einzelpersonen und Gesellschaften in solchen Phasen sicherzustellen. Im Kontext der Flüchtlingswellen konzentrieren wir uns auf die Gruppe der syrischen Geflüchteten, die ab 2015 in Deutschland angekommen sind, weil sie eine große kohärente Flüchtlingsgemeinschaft bilden. Insbesondere befassen wir uns mit der Rolle der IKT bei der sozialen Eingliederung von Geflüchteten in die Gesellschaft und der Frage, wie verschiedene IKT-Dienste (insbesondere Smartphones und soziale Netzwerke) eine bessere Integration und soziale Eingliederung von Geflüchteten fördern können. Im Zusammenhang mit der COVID-19-Pandemie konzentrieren wir uns auf das weit verbreitete unkonventionelle Arbeitsmodell „Work from Home“ (WFH). Unsere Forschung in diesem Zusammenhang fokussiert sich auf die Hauptkomponenten der Arbeit von zuhause und die Hauptunterschiede bei WFHErfahrungen, die auf persönlichen Merkmalen, z.B. Geschlecht und Familiensituation, beruhen. Wir konnten neue Erkenntnisse gewinnen, die sich auf folgenden vier etablierten Forschungsmethoden stützen: Literaturrecherche, Mixed-Methoden, qualitative Methoden und quantitative Methoden. Die Ergebnisse unserer Forschung wurden in acht Forschungsartikeln innerhalb von relevanten Tagungen und Fachzeitschriften für Informationssysteme veröffentlicht. Zu den wichtigsten Erkenntnissen der Forschung zur Rolle der IKTs bei der Integration Geflüchteter gehören: Smartphones sind ein zentrales Element der IKT-Nutzung von Geflüchteten. Sie betrachten IKT als Informations- und Machtquelle. Die soziale Verbundenheit von Geflüchteten hängt stark mit ihrer Internetnutzung zusammen. Sie verlassen sich nicht nur auf traditionelle Methoden, um die deutsche Sprache zu lernen und sich weiterzubilden. Die Möglichkeit, das Smartphone jederzeit und überall zu nutzen, gibt Geflüchteten ein Gefühl der globalen Vernetzung und IKT tragen dazu bei, Geflüchtete in folgenden drei Punkten zu stärken: Beteiligung an der Gemeinschaft, Gefühl der Kontrolle und Selbstwirksamkeit. Zu den wichtigsten Erkenntnissen aus dem COVID-19-WFM-Stream gehören: Das Geschlecht und die Anwesenheit von Kindern unter 18 Jahren beeinflussen die Kontrolle der Arbeitnehmer über ihre Zeit, den technologischen Nutzen und den WFH-Konflikt, ohne jedoch ihre Einstellung zu WFH zu beeinträchtigen. Sowohl persönliche als auch technologische Faktoren beeinflussen die Einstellung eines Einzelnen zur Arbeit von zuhause und seine Produktivität. Zum Zeitpunkt der Einreichung dieser Dissertation werden in fortlaufenden Forschungsprojekte weitere Erkenntnisse zu diesem Themenbereich gesammelt. Diese Dissertation trägt einerseits zur Diskussion innerhalb der Gesellschaft für Informationssysteme bei, indem sie aufzeigt wie verschiedene IKT-Lösungen eingesetzt werden können, um die soziale Eingliederung von Geflüchteten in ihren neuen Gemeinschaften zu fördern und so zu einer integrativen Gesellschaft beizutragen. Andererseits steuert die Dissertation neues Wissen zu der Forschung über COVID-19 bei, insbesondere zur Umstellung des Arbeitsumfelds im Kontext von Heimarbeit (WFH). Die im Rahmen dieser Arbeit gesammelten Erkenntnisse tragen maßgeblich dazu bei, theoretische Implikationen und zukünftige Forschungsmöglichkeiten auf dem Gebiet der Informationssysteme aufzudecken. Ferner werden praktische Implikationen für relevante Stakeholder und soziale Auswirkungen im Zusammenhang mit der Flüchtlingskrise und der COVID-19-Pandemie adressiert, die in Zukunft entscheidend und wichtig sein werden.

The information systems (IS) community has begun to research how information and communications technologies can assist immigrants and refugees, such as by examining how countries can facilitate social-inclusion processes. Migrants face the challenge of joining closed communities that cannot integrate or fear doing so. We conducted a panel discussion at the 2019 Americas Conference on Information Systems (AMCIS) in Cancun, Mexico, to introduce multiple viewpoints on immigration. In particular, the panel discussed how technology can both support and prevent immigrants from succeeding in their quest. We conducted the panel to stimulate a thoughtful and dynamic discussion on best practices and recommendations to enhance the discipline's impact on alleviating the challenges that occur for immigrants in their host countries. In this panel report, we introduce the topic of using ICT to help immigrants integrate and identify differences between North/Central America and Europe. We also discuss how immigrants (particularly refugees) use ICT to connect with others, feel that they belong, and maintain their identity. We also uncover the dark and bright sides of how governments use ICT to deter illegal immigration. Finally, we present recommendations for researchers and practitioners on how to best use ICT to assist with immigration.

This sudden venue change can affect academics' productivity and exacerbate the challenges that confront universities as they face an uncertain future. In this paper, we identify factors that influence academics' productivity while working from home during the mandate to self-isolate. From analyzing results from a global survey we conducted, we found that both personal and technology-related factors affect an individual's attitude toward working from home and productivity. Our results should prove valuable to university administrators to better address the work-life challenges that academics face.

Like other types of contributions to public goods, personal data are likely to be underprovided. We investigate whether classical remedies to underprovision are also applicable to personal data and whether the privacy-sensitive nature of personal data must be additionally accounted for. In a randomized field experiment on a public online education platform, we prompt users to complete their profiles with personal information. Compared to a control message, we find that making public benefits salient increases the number of personal data contributions significantly. This effect is even stronger when additionally emphasizing privacy protection, especially for sensitive information. Our results further suggest that emphasis on both public benefits and privacy protection attracts personal data from a more diverse set of contributors.
