Alexa, Can You Help Me Solve That Problem? - Understanding the Value of Smart Personal Assistants as Tutors for Complex Problem Tasks
(universi - Universitätsverlag Siegen, 2019)
In recent decades, the number of students per lecturer at universities has constantly risen. In these learning scenarios, individual lecturer support for helping students actively acquiring new knowledge is hardly possible. However, active student behavior is necessary for successful learning. Smart Personal Assistants such as Amazon’s Alexa or Google’s Home promise to fill this gap by being students’ individual tutors. In order to understand what students expect from Smart Personal Assistants as tutors and how they ...

Classifying Smart Personal Assistants: An Empirical Cluster Analysis
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The digital age has yielded systems that increasingly reduce the complexity of our everyday lives. As such, smart personal assistants such as Amazon’s Alexa or Apple’s Siri combine the comfort of intuitive natural language interaction with the utility of personalized and situation-dependent information and service provision. However, research on SPAs is becoming increasingly complex and opaque. To reduce complexity, this paper introduces a classification system for SPAs. Based on a systematic literature review, a ...

Alexa, Can You Help Us Solve This Problem? How Conversations With Smart Personal Assistant Tutors Increase Task Group Outcomes
(Association for Computing Machinery, 2019)
Despite a growing body of research about the design and use of Smart Personal Assistants, existing work has mainly focused on their use as task support for individual users in rather simple problem scenarios. Less is known about their ability to improve collaboration among multiple users in more complex problem settings. In our study, we directly compare 21 groups who either use a Smart Personal Assistant tutor or a human tutor when solving a problem task. The results indicate that groups interacting with Smart ...

Insights into Using IT-Based Peer Feedback to Practice the Students Providing Feedback Skill
(University of Hawaii at Manoa, Hamilton Library, ScholarSpace, 2019)
The skills students need nowadays have changed over the last decades. The required skills are shifting more and more towards higher order thinking skills, such as critical thinking, collaboration and communication. One of the main ways of practicing these skills is through formative feedback, which consists of self-assessment and peer-assessment in our setting.
However, today’s lecturers are facing the challenge that the number of students per lecture is continuously increasing, while the available budget is stagnating. ...

Machines as teammates: A research agenda on AI in team collaboration
(2019-07-06)
What if artificial intelligence (AI) machines became teammates rather than tools? This paper reports on an international initiative by 65 collaboration scientists to develop a research agenda for exploring the potential risks and benefits of machines as teammates (MaT). They generated 819 research questions. A subteam of 12 converged them to a research agenda comprising three design areas – Machine artifact, Collaboration, and Institution – and 17 dualities – significant effects with the potential for benefit or harm. ...

Why different trust relationships matter for information systems users
(2015-12-08)
Technology acceptance research has shown that trust is an important factor fostering use of information systems (IS). As a result, numerous IS researchers have studied factors that build trust in IS. However, IS research on trust has mainly focused on the trust relationship between the user and the IS itself, largely neglecting that other targets of trust might also drive IS use from a user’s point of view. Accordingly, we investigate the importance of different targets of trust in IS use. Therefore, we use the concept ...

Process is King: Evaluating the Performance of Technology-mediated Learning in Vocational Software Training
(2018-09-01)
Technology-mediated learning (TML) is a major trend in education, since it allows to integrate the strengths of traditional- and IT-based learning activities. However, TML providers still struggle in identifying areas for improvement in their TML offerings. One reason for their struggles is inconsistencies in the literature regarding drivers of TML performance. Prior research suggests that these inconsistencies in TML literature might stem from neglecting the importance of considering the process perspective in ...

Der Momentum-Effekt und Momentum-Handelsstrategien
(2016-01-14)
Diese Arbeit weist Momentum-Renditen für europäische Aktien im Zeitraum von 1991 bis 2010 nach, die – je nach Top/Flop-Prozentsatz – vor Kosten zwischen 6 und 19% p.a. liegen. Gleichzeitig liegen mit hohen Standardabweichungen, negativen Schiefe-Werten und hohen Drawdowns drei wesentliche Risikofaktoren vor. Für die Kernuntersuchungen des Top/Flop-Wertes von 5% treten die höchsten Momentum-Renditen von mehr als 10% p.a. für Ranking-Perioden von 80 bis 100 und Holding-Perioden von 60 bis 90 Handelstagen auf. Grundsätzlich ...

Möglichkeiten zur Verwaltungsentwicklung auf der Basis einer Prozessgestaltung im IT-Labor, untersucht am Beispiel der Implementierung von E-Government bei der hessischen Landeshauptstadt Wiesbaden
(2011-03-29)
In der vorliegenden Arbeit wird nach Wegen zur Steigerung der Effektivität von Implementationsprozessen umfassender IT-Anwendungen in großen Kommunalverwaltungen gesucht, da nach vorliegenden Schätzungen allenfalls 10 % der großen IT-Projekte der öffentlichen Verwaltungen zielkonform und erfolgreich umgesetzt werden. Analysen zeigen, dass die in solchen Prozessen auftretenden Interdependenzen von Technologie, Organisation und Mensch oft nicht angemessen berücksichtigt wurden.
Die zentrale Fragestellung der vorliegenden ...

Strategische Erfolgsfaktoren für ein kosten-risiko-optimales Public Debt Management - Organisatorische und inhaltliche Parameter im internationalen Vergleich
(2013-06-07)
Aus den im Rahmen dieser Forschungsarbeit empirisch gewonnenen Erkenntnissen werden Gestaltungsempfehlungen für das Public Debt Management abgeleitet. Diese zeigen, dass ein wirtschaftliches Public Debt Management nicht ein ausschließlich kostenminimierendes (sparsames), sondern ein kosten-risiko-optimales Public Debt Management mit effektiven internen und externen Überwachungsinstrumenten und wirksamer externer Finanzkontrolle sein muss.
