Are Two Better than One?

Das Konzept der Hybriden Intelligenz gewinnt zunehmend an Popularität (Horvitz 2014). Dieses Konzept zielt darauf ab, die komplementären Stärken von menschlicher Intelligenz und KI zu nutzen, um sich intelligenter zu verhalten, als es jede der beiden für sich genommen sein könnte (Kamar 2016). Die Integration von menschlichem Input in die künstliche Intelligenz bringt jedoch Herausforderungen mit sich, da insbesondere die menschliche Intelligenz nur dann integriert werden kann, wenn bestimmte organisatorische Randbedingungen adäquat berücksichtigt werden (Kamar 2016). Im Rahmen des vorliegenden Grundlagenforschungsfondsprojekts wird daher untersucht welche Auswirkungen der Einsatz hybrider Intelligenz auf die Performanz sozio-technischer Systeme hat.

Design Principles for Service Systems in the Internet of Things

The Internet of Things (IoT)–understood as digitizing and connecting the physical world and its objects–uses a multitude of technologies to bring along many technical advancements. Overall, IoT is expected to have tremendous economic impact in the nearer future and to affect all sectors and settings of our business and private lives, e.g. in manufacturing, smart cities, healthcare, etc. Thereby, the value IoT systems can deliver depends on the services they can offer to users and customers. To leverage the potentials of IoT and its technical feasibility and superiority, not only the purely technological connectedness of things, but also the interplay and design of interfaces between IoT and people are crucial, i.e. people, software and hardware need to be orchestrated.To realize this interplay between IoT hardware, IoT software and people, all need to be integrated into existing value networks, e.g. patients and physicians need to be an integral part when designing IoT systems for medication adherence. While current research mainly focuses on empirically analyzing IoT systems and its effects, research concentrating on design knowledge for IoT systems is missing. The project wants to close this research gap and extend the existing body of knowledge by generating design knowledge for this highly promising area. To describe the involved stakeholders and technologies of IoT systems, the concept of service systems is used and a sociotechnical system’s perspective is taken. Service systems are defined as value-co-creation configurations of people, technology and value propositions, e.g. patients and their relatives, physicians and care personnel as the involved “people” who are “co-creating value” by working together to improve the patient’s quality of life while using “technology” such as IoT devices or infrastructures.

Enhancing Student Performance Through Formative Feedback in Large Scale University Lectures (SNF Doc Mobility)

In einer 10. Klasse des Gymnasiums und einer Berufsschulklasse bearbeitete eine Gruppe die Aufgaben mit Hilfe eines Smart Personal Assistants, die andere Gruppe mit “traditionellen” Methoden. Die empirischen Ergebnisse zeigten, dass die Schüler in den Experimentierklassen signifikant mehr Problemlösungskompetenzen erwarben als die Schüler in den Kontrollklassen und sich die Lernprozesse veränderten. Die Ergebnisse liefern erste empirische Belege für den Wert des Einsatzes von Smart Personal Assistants wie z.B. Alexa auf die Fähigkeiten zum Lösen von Problemen.

IS Architecture

This project investigates IS architecture from two distinctive, but interrelated perspectives. While the first part of the project employs a static approach to explain which institutional factors underlie desirable outcomes for IS architecture, the second part opts for a dynamic approach to explain how IS architecture evolves over time. This project combines both static and dynamic explanations to triangulate the generated theories on IS architecture.

While digital transformation as a research phenomenon per se gains acceptance in both practice and academia, its precise conceptualization and theoretical underpinnings are discussed. To address these gaps, we propose a critical realist view on Digital Transformation. Building on a literature review on generative mechanisms in digital transformation studies, we show how the concept of generative mechanisms is used and what types of generative mechanisms are adopted. Based on our findings, we propose a research agenda that encourages further studies on digital transformation, taking a critical realist stance. Thus, we put forward ways of applying critical realism to digital transformation studies and show how critical realism can advance research through its ability for multi-level analysis and its unique understanding of change and transformation.

Volatility, uncertainty, ambiguity, and complexity (VUCA) are drivers in today’s business world. Therefore, an increasing number of organizations implement agility (agile methods) to cope with the rapid and accelerating change. However, these agile transformations do not succeed unhindered, and some fail. One reason for that is the employees lacking an agile mindset and they do not support or participate in the transformation. So far, knowledge of the agile mindset is in its infancy. A conceptualization for developing a measuring instrument on the individual level is lacking. Furthermore, the relevance of the agile mindset regarding organizational performance in a VUCA world is still unclear. Our study aims to close this gap. To do so, we examine the agile mindset with 15 qualitative interviews and conduct an online survey (N=449) to predict organizational agility and organizational performance based on the agile mindset. As for results, we conceptualize the agile mindset as an attitude that comprises four dimensions: ’learning spirit’, ‘collaborative exchange’, ‘empowered self-guiding’, and ‘iterative value creation’. We have found an indirect effect of the agile mindset affecting organizational performance towards organizational agility. These findings contribute to the agility and management research by providing both a conceptualization and a measuring instrument for the agile mindset. Furthermore, the agile mindset´s relevance in agile transformation is explained and its relation to organizational performance outlined. For successful agile transformation, executives must focus on the agile mindset of their employees and foster this by e.g. being a role model.

We present an annotation approach to capturing emotional and cognitive empathy in student-written peer reviews on business models in German. We propose an annotation scheme that allows us to model emotional and cognitive empathy scores based on three types of review components. Also, we conducted an annotation study with three annotators based on 92 student essays to evaluate our annotation scheme. The obtained inter-rater agreement of α = 0.79 for the components and the π = 0.41 for the empathy scores indicate that the proposed annotation scheme successfully guides annotators to a substantial to moderate agreement. Moreover, we trained predictive models to detect the annotated empathy structures and embedded them in an adaptive writing support system for students to receive individual empathy feedback independent of an instructor, time, and location. We evaluated our tool in a peer learning exercise with 58 students and found promising results for perceived empathy skill learning, perceived feedback accuracy, and intention to use. Finally, we present our freely available corpus of 500 empathy-annotated, student-written peer reviews on business models and our annotation guidelines to encourage future research on the design and development of empathy support systems.

Wearables are used to help motivate individuals to trade their unhealthful behaviors for beneficial ones, thereby preventing the diseases of affluence, which are caused by a sedentary lifestyle. However, inconclusive study results regarding the effectiveness of wearables raise questions about the outcomes of using wearables. Research on the topic paints an ambiguous picture regarding the support wearables offer users in performing beneficial health-related behaviors, leaving the underlying mechanisms of wearable use and its outcomes unexplained. We seek to fill this gap in the literature by means of a critical realist study based on thirty narrative interviews with long-term users of wearables. By identifying seven generative mechanisms that drive users’ interactions with wearables and the subsequent cognitive and behavioral outcomes of that use, we answer the research question concerning how and why users’ interactions with wearables can facilitate positive behavioral and cognitive outcomes. The study makes several contributions to theory and practice.

Gendered voice based on pitch is a prevalent design element in many contemporary Voice Assistants (VAs) but has shown to strengthen harmful stereotypes. Interestingly, there is a dearth of research that systematically analyses user perceptions of different voice genders in VAs. This study investigates gender-stereotyping across two different tasks by analyzing the influence of pitch (low, high) and gender (women, men) on stereotypical trait ascription and trust formation in an exploratory online experiment with 234 participants. Additionally, we deploy a gender-ambiguous voice to compare against gendered voices. Our findings indicate that implicit stereotyping occurs for VAs. Moreover, we can show that there are no significant differences in trust formed towards a gender-ambiguous voice versus gendered voices, which highlights their potential for commercial usage.

Bürgerbeteiligung war und ist wichtig – insbesondere in Zeiten von Covid-19. Dabei bedarf es einer sinnvollen Kombination und einer guten Verzahnung von digitalen und analogen Angeboten, wobei insbesondere im Kontext von Covid-19 die Frage bezüglich digitaler Bürgerbeteiligung im Raum steht: Wenn nicht jetzt, wann dann? Wir sprechen uns für Formen digitaler Bürgerbeteiligung aus, die bestehende Formen nicht ersetzen, sondern synergetisch ergänzen. Um dies zu tun, zeigen wir in diesem Beitrag auf, wie das Konzept des Government-as-a-Platform hierbei zu verstehen ist und helfen kann. Außerdem beschreiben wir Konzeption, Entwicklung und Integration einer digitalen Bürgerbeteiligungsplattform, die sich unter anderem durch die Verzahnung von Top-down- und Bottom-up-Elementen wie auch durch Transparenz der Plattform-Prozesse auszeichnet. Bürger*innen werden dabei als Expert*innen ihres Alltags gesehen und dazu empowert, durch eigene Projektvorschläge ihre Stadt proaktiv mitzugestalten.

This paper introduces a framework for managing bias in machine learning (ML) projects. When ML-capabilities are used for decision making, they frequently affect the lives of many people. However, bias can lead to low model performance and misguided business decisions, resulting in fatal financial, social, and reputational impacts. This framework provides an overview of potential biases and corresponding mitigation methods for each phase of the well-established process model CRISP-DM. Eight distinct types of biases and 25 mitigation methods were identified through a literature review and allocated to six phases of the reference model in a synthesized way. Furthermore, some biases are mitigated in different phases as they occur. Our framework helps to create clarity in these multiple relationships, thus assisting project managers in avoiding biased ML-outcomes.

Research Talk Dominik Gutt: The Rise of Robo-Reviews – The Effects of Chatbot-Mediated Review Elicitation on Online Reviews

16. September 2021

Standort: Universität St. Gallen, Dufourstrasse 50, 9000 St. Gallen

Datum: 16.09.2021, 10:00 bis 12:00

Dominik Gutt,  Assistant Professor at Rotterdam School of Management; “The Rise of Robo-Reviews – The Effects of Chatbot-Mediated Review Elicitation on Online Reviews”

Chatbots have been introduced as a new way to receive product reviews. However, little is known how the chatbot-mediated solicitation influences review characteristics such as the valence or the helpfulness. We conduct four studies to narrow this literature gap. Our results show that (1) chatbot-mediated review elicitation leads to a positivity bias in ratings, particularly strong for low-quality products; (2) chatbot-mediated reviews negatively impact a range of review dimensions (e.g., helpfulness) mainly due to decreased review length, (3) the positivity bias varies depending on the level of anthropomorphism in the chatbot and the nature of the survey deployer (seller vs. platform), and can be explained by audience tuning due to social presence. Our research is among the first to uncover a link between chatbot use, review valence, and other valuable review

Research Talk Dr. Monika Malinova Mandelburger: Cognitive diagram understanding and task performance in systems analysis and design

Dr. Monika Malinova Mandelburger, WU Wien; “Cognitive diagram understanding and task performance in systems analysis and design”

Diagrams play an important role in Systems Analysis and Design (SAD). So far, cognitive research on diagram criteria in relation to task performance has been fragmented. The aim of this talk is to (1) discuss the cognitive processing steps involved during understanding and task performance with diagrams, (2) discuss criteria for such diagrams to best support cognitive processing and (3) demonstrate the support effective diagrams provide for performing SAD tasks. First, we present a theoretical cognitive framework of task performance with diagrams called CogniDia. It integrates different cognitive theories from research on diagrams in software engineering and information systems. Second, we present findings from a literature review on criteria for effective cognitive processing of diagrams. Third, we use the theoretical cognitive framework CogniDia to investigate how diagrams support the SAD process effectively.

Monika Malinova is a postdoctoral researcher with the Institute for Information Business at the Vienna University of Economics and Business (WU Vienna), Austria. She obtained her PhD degree in 2016 from WU Vienna. Her PhD thesis was awarded the Dr. Maria Schaumayer award for an excellent dissertation of 2016.  In 2015 Monika was awarded the Internationalization Program Scholarship from the Dr. Maria Schaumayer Foundation.

Research Talk Henderik Proper: Fundamental challenges in systems modelling

26. September 2019

Standort:

Prof. Henderik Proper, Luxemburg Institute of Science and Technology (LIST); Fundamental challenges in systems modelling

Abstract: In the context of information systems, and digital ecosystems at large, many different forms of systems modelling are used. This includes: enterprise (architecture) modelling, business process modelling, ontology modelling and information modelling. The resulting models have come to play an important role during all stages of the life-cycle of digital (eco)systems.

In our view, the key role of models also fuels the need for a more fundamental reflection on core aspects of modelling itself. In line with this, the goal of this presentation is to explore some of the underlying fundamental challenges of modelling, and in doing so create awareness for, and initiate discussions on, the need for more foundational research into these challenges.

The discussion of these challenges has been structured in terms of three clusters: the semiotic foundations, the essence of modelling, and the role of normative frames (such as modelling languages).

Research Talk Sunil Wattal: Competitive Poaching in Search Advertising: A Randomized Field Experiment

16. July 2019

Standort:

Prof. Sunil Wattal, Assistociate Professor at Fox School of Business, Temple University, Philadelphia; “Competitive Poaching in Search Advertising: A Randomized Field Experiment”

Abstract: Keyword searches with brand names occur very commonly on search engines, which enables firms to infer not only when customers are searching for them, but also when customers are searching for their competitors. In other words, firms can generate traffic from search engine advertising by bidding not only on their own keywords but also on competitors’ keywords. The strategy of bidding on competitors’ keywords, known as competitive poaching, presents unique opportunities for academic research.

In this research, we examine the factors that influence the effectiveness of competitive poaching, specifically the role of different ad copies and the type of competitor (poached brand) that a brand is “poaching” from. We also examine how competing sponsored ads from the poached brand and other advertisers have an impact on competitive poaching. We run a field experiment for a three-month period with a business school in northeastern United States, by bidding on keywords of competing schools and randomly displaying different types of ad copies. We find that ad copies that feature vertical differentiation are more effective than other ad copies when poaching on keywords of high-quality brands. We also find that when poaching from low-quality brands, ad copies featuring horizontal differentiation perform better than other ad copies. We further show that the presence of the poached brand’s own ad leads to a positive impact when that brand is high-quality, and a negative impact if the poached brand is low-quality. Finally, we also find that the presence of other advertisers using quality signals in their ad copies has a positive impact on clicks. However, use of vertical differentiation ad copies by the focal brand negatively moderates the impact of  the presence of other advertisers using quality signals. The academic and managerial contributions are also discussed.

Balancing exploration and exploitation in information system development: Four Types of agile ambidexterity

The achievement of ambidexterity is success-critical for an ISD team because it translates into a vital balance between exploration and exploitation. Yet, having this balance is challenging because the ISD team has only limited time and attention to commit to satisfying the needs of exploration and exploitation. Prior research suggests a combination of the traditional – waterfall ISD method – with the agile ISD method to achieve the balance of explore and exploit and thus to be ambidextrous. However, the combination approach does not work for ISD teams that want to avoid using practices from the traditional ISD method and seek to stay within the agile ISD method only. The literature is silent on how an ISD team can achieve ambidexterity under these conditions. We draw on the literature on ambidexterity and use a theoretical framework of four types of ambidexterity to gain a better understanding of how ISD teams balance exploration and exploitation in order to be ambidextrous. In a qualitative case study, we examine how the ISD team masters the achievement of ‘agile’ ambidexterity. Our key theoretical contribution is a deeper theoretical understanding on the achievement of four types of ambidexterity that range from the individual to the organization and encompass bottom-up/emergent and top-down/management approaches. The practical implications of the research are relevant for organizations and managers concerning how the types and levels of ambidexterity might be managed, both separately and collectively.
