A method for developing Reference Enterprise Architectures

Industrial change forces enterprises to constantly adjust their organizational structures in order to stay competitive. In this regard, research acknowledges the potential of Reference Enterprise Architectures (REA). This thesis proposes REAM - a method for developing REAs. After contrasting organizations' needs with approaches available in the current knowledge base, this work identifies the absence of method support for REA development. Proposing REAM, the author aims to close this research gap and evaluates the method's utility by applying REAM in different naturalistic settings

License to Supervise:Influence of Driving Automation on Driver Licensing

To use highly automated vehicles while a driver remains responsible for safe driving, places new – yet demanding, requirements on the human operator. This is because the automation creates a gap between drivers’ responsibility and the human capabilities to take responsibility, especially for unexpected or time-critical transitions of control. This gap is not being addressed by current practises of driver licensing. Based on literature review, this research collects drivers’ requirements to enable safe transitions in control attuned to human capabilities. This knowledge is intended to help system developers and authorities to identify the requirements on human operators to (re)take responsibility for safe driving after automation

Insights from mechanistic and digital intervention approaches

Eine effektive Förderung des Sozialverhaltens autistischer Kinder erfordert ein tiefgehendes Verständnis der Ursachen maladaptiver Reaktionen und die Bereitstellung eines leicht verfügbaren Förderangebots. Hier haben digitale Angebote ein großes Potential. Ebenso wie bei der Ursachenforschung mangelt es jedoch an Forschungsansätzen, welche eine Vielzahl an kognitiven und emotionalen Prozessen in die digitale Förderung integrieren. Dementsprechend untersuchte die Dissertation zunächst das Zusammenspiel verschiedener Ursachen aggressives Sozialverhaltens anhand eines etablierten Modells der sozial-kognitiven Informationsverarbeitung. Durch die Integration verschiedener Facetten der Empathie und deren zugrundeliegende Kompetenzen in ein digitales Förderangebot sollte im zweiten Schritt eine Verbesserung des Sozialverhaltens autistischer Grundschüler:innen erreicht werden. Es zeigte sich, dass Emotionsdysregulation verschiedene Formen aggressiven Sozialverhaltens und damit assoziierte feindselige Attributionen verstärkt. Letztere stand vor allem mit verbalen und verdeckten Aggressionsformen sowie mit guten Emotionserkennungsfertigkeiten im Zusammenhang. Eine Verbesserung des Sozialverhaltens und der Emotionsregulation konnte mittelfristig durch das sechswöchige, eltern-begleitete eLearningprogramm „Zirkus Empathico“ erreicht werden. Die multizentrische, randomisiert kontrollierte Studie ergab zudem kurzfristige und moderate Interventionseffekte für Empathie und Emotionserkennung als primäre Endpunkte. Insgesamt unterstreicht die Dissertation die Validität etablierter Modelle der sozialen Informationsverarbeitung sowie die Relevanz, diese zukünftigen Forschungs- und Interventionsansätzen zugrunde zu legen. Durch die Integration verschiedener sozio-emotionaler Kompetenzen scheint die digitale Intervention Zirkus Empathico prosoziales Verhalten autistischer Kinder auf effektive und praktikable Weise zu fördern.Effective training of autistic children`s social behavior requires an in-depth understanding of the causes of maladaptive responses and the provision of easily accessible support services. In this context, digital interventions have great potential. However, there is a lack of research approaches that integrate a variety of cognitive and emotional processes into both, explanation and digital support. The present dissertation first examined the interplay of different causes of aggressive social behavior by applying an established model of social-cognitive information processing to a sample of autistic elementary school students. Second, by integrating different facets of empathy and their underlying competencies into a digital program, the social behavior of autistic elementary school children should be improved. First, it was shown that emotion dysregulation strengthens various forms of aggressive social behavior and associated hostile attribution biases. The latter was mainly related to verbal and covert forms of aggression and good emotion recognition skills. Second, the parent-assisted eLearning program "Zirkus Empathico" led to a medium-term improvement in social behavior and emotion regulation after a six-week training. In addition, the multicenter randomized controlled trial showed moderate intervention effects on empathy and emotion recognition as primary outcomes, which were no longer detectable three months later. Overall, the dissertation highlights the validity of established models of social information processing and the relevance of using them as a foundation for future research and intervention. By integrating various socio-emotional competencies, the digital intervention Zirkus Empathico seems to strengthen autistic children’s prosocial behavior effectively and feasibly

A Review of Research on Driving Styles and Road Safety

Objective: To outline a conceptual framework for understanding driving style and, based on this, review the state-of-the-art research on driving styles in relation to road safety.</br></br> Background: Previous research has indicated a relationship between the driving styles adopted by drivers and their crash involvement. However, a comprehensive literature review of driving style research is lacking. </br></br> Method: A systematic literature search was conducted, including empirical, theoretical and methodological research on driving styles related to road safety. </br></br> Results: A conceptual framework was proposed where driving styles are viewed in terms of driving habits established as a result of individual dispositions as well as social norms and cultural values. Moreover, a general scheme for categorising and operationalizing driving styles was suggested. On this basis, existing literature on driving styles and indicators was reviewed. Links between driving styles and road safety were identified and individual and socio-cultural factors influencing driving style were reviewed. </br></br> Conclusion: Existing studies have addressed a wide variety of driving styles, and there is an acute need for a unifying conceptual framework in order to synthesise these results and make useful generalisations. There is a considerable potential for increasing road safety by means of behaviour modification. Naturalistic driving observations represent particularly promising approaches to future research on driving styles. </br></br> Application: Knowledge about driving styles can be applied in programmes for modifying driver behaviour and in the context of usage-based insurance. It may also be used as a means for driver identification and for the development of driver assistance systems

Older people’s appropriation of computers and the Internet

This thesis looks at how older people integrate computers and the Internet into their everyday lives and make these technologies their own as part of their broader experience of ageing. The thesis starts by considering the limits of current ‘deficit-driven’ models of accessible design used in relation to older people and highlights a need to develop new approaches which can accommodate the adaptive and ‘positive’ capacities that emerge with advanced age. The approach subsequently developed provides a consideration of older people’s situated and subjective experiences in relation to computer and Internet engagement as part of their adaptations to ageing. Qualitative and ethnographic data in the form of participant observations, contextual interviews and video-based observations are all used to examine the ways in which older users identify computers and the Internet as relevant and construct meaningful uses for them over time. Four case studies are used to explore the contextual and subjective determinants of these emerging psycho-socio-technical relationships over time and in different contexts. Through grounded analysis patterns are established in the data which outline persistent qualities of these emerging relationships in relation to ageing. A psycho-socio-technical process known as ‘appropriation’ is used to frame these adaptive relationships as they develop over time. In contrast to existing models of accessibility this analysis shows computer and Internet appropriation to be driven primarily by positive adaptations to ageing rather than its deficits. Six ‘core themes of relevance’ are identified across the studies (social contact; acquiring knowledge; supporting independence; intergenerational connection; reminiscence and life review and creativity) which represent age-relevant motivations that can be used as the basis for accessible designs promoting appropriation. In addition appropriation is outlined as a cumulative developmental process with distinct phases over time. This provides a structure for supporting older people’s appropriation of computers and the Internet whilst maintaining an emphasis on well-being. Finally this thesis contributes to understandings of contemporary ageing, offering insights into the potential for computers and the Internet to change the ageing experience in developed societies

The Relationship between Complex Problem Solving and Intelligence: An Analysis of Three Computer Simulated Scenarios

The gap between field research and laboratory research has always been a problem in psychology. With the introduction of computers into the laboratory, computer simulated tasks allowed the observation of complex problem solving performance in the laboratory with a higher degree of ecological validity than ever before. The main aim of this thesis was to explore the relationship between complex problem solving ability and intelligence by presenting the results of two studies, using over 400 adults. Complex problem solving ability was assessed by performance on three computer simulations: Furniture Factory, Tailorshop, and Forestry System. The theory of fluid and crystallised intelligence guided the selection of cognitive abilities tests. Relationships between broad cognitive abilities including Fluid reasoning (Gf), Acculturation knowledge (Gc), Visual processing (Gv), Quantitative knowledge (Gq), and Processing speed (Gs) with computer simulation performance were explored. Previous research exploring the relationship between complex problem solving and intelligence has led to inconsistent and often contradictory findings. Scoring problems in previous research were addressed and for all three computer simulations, relationships between intelligence and complex problem solving were found. Overall, Gf and Gc explained 20% of the variance in complex problem solving. Correlations between intelligence and complex problem solving increased when specific cognitive abilities tests and aggregated computer simulation scores were employed, rather than the employment of general or factor scores of intelligence and final computer simulation scores. A new aggregated scoring technique (goal achievement) that allowed consistent scoring across different computer simulations was developed. The strongest relationship between intelligence and complex problem solving was observed between goal achievement scores and specific tests of cogn itive abilities such as esoteric analogies and critical reas! oning. There were significant correlations between goal achievement on the Furniture Factory and both esoteric analogies and critical reasoning (r = .37, p < .05, r = .41, p < .05) respectively. Correlations between goal achievement on the Tailorshop and both esoteric analogies and critical reasoning were significant (r = .25, p < .05, r = .29, p < .05) respectively. Correlations between goal achievement on the Forestry System and both esoteric analogies and critical reasoning were also significant (r = .38, p < .05, r = .30, p < .05) respectively. In addition, performance scores on all three computer simulations were correlated with one another. These findings support the application of the Brunswik lens model to complex problem solving research. Negative correlations, albeit rather modest, were observed between neuroticism and complex problem solving performance on the Furniture Factory (r = -.17, p < .05) and the Tailorshop (r = -.21, p < .05), indicating that emoti on may also mediate complex problem solving performance. Results of this thesis may bring individual differences research in this area a step closer to obtaining stable results from which generalisations about complex problem solving tasks can be made

Transference of relationship qualities to a virtual world

This dissertation investigates to which extent internal working models of relationships and personality characteristics of participants are transferred to computer-generated agents in a virtual social environment (VSE). For this purpose a VSE was created that was populated with several autonomous agents which interacted with each other. Participants can control one of the the agents (the "protagonist"); one of the other agents is the spouse of the protagonist. Using this setup, a potential projection screen for the dynamics of the real-life relationship, as well as for generalized internal working models was created. Chapter 1 summarizes the research question, gives an overview of the development of the VSE called "Simoland", and provides a general summary and conclusion about the dissertation. Chapters 2 - 4 each are self-contained manuscripts. Chapter 2 („The challenge of constructing psychologically believable agents“) is a theoretical article which describes challenges and new possibilities in the implementation of psychological models into autonomous agents. Chapter 3 („Virtual social environments as a tool for psychological assessment: Dynamics of interaction with a virtual spouse“) describes the first empirical study conducted in Simoland. This study demonstrates how intrapersonal changes in interaction behavior can be investigated in VSEs. With a sample of 236 participants I could show that both the relationship satisfaction with the real life partner, and the intimacy motive of the participant had an influence on the behavior towards the virtual spouse. Hence, it could be shown that virtual behavior indeed is connected to conditions of the real world. While the first study investigated unrestricted behavior in an open world, in Chapter 4 („Transference of adult attachment dynamics to a virtual spouse“) specific, theoretically derived scenes were created which were supposed to activate the attachment system. With a sample of 422 participants we could demonstrate interindividual differences in attachment behavior as a reaction to one of three scenes: a separation, a conflict with the virtual spouse, and a threatening situation. Both attachment anxiety and attachment avoidance significantly and meaningfully correlated with the behavior in the VSE, the physical distance between protagonist and virtual spouse, and emotional ratings. To summarize, this dissertation for the first time shows that qualities of real-life relationships, as well as internal working models of attachment, are transferred to virtual agents. Thereby new ways are opened to investigate behavior in close relationships and representations of significant others through virtual scenarios.Diese Dissertation untersucht, inwieweit Beziehungsrepräsentationen und Persönlichkeitsmerkmale von Personen auf computergenerierte Agenten in einer virtuellen sozialen Umgebung (VSU) übertragen werden. Dazu wurde eine VSU erstellt, in der Teilnehmer eine virtuelle Figur (den „Protagonisten“) steuern können, welche wiederum mit anderen autonomen Agenten interagiert. Einer dieser anderen Agenten ist der virtuelle Partner/ die virtuelle Partnerin des Protagonisten, womit eine mögliche Projektionsfläche für die Beziehungsdynamik der realen Partnerschaft sowie für generalisierte interne Arbeitsmodelle von Beziehungen hergestellt wurde. Kapitel 1 fasst die Forschungsfrage zusammen und beschreibt den Entstehungsprozess der VSU namens „Simoland“, und gibt eine kurze Zusammenfassung der Gesamtergebnisse. Kapitel 2 – 4 stellen jeweils eigenständige Manuskripte dar. Kapitel 2 („The challenge of constructing psychologically believable agents“) ist ein theoretischer Artikel, der Herausforderungen und neue Wege beschreibt wie psychologische Modelle in autonome Agent implementiert werden können. Kapitel 3 („Virtual social environments as a tool for psychological assessment: Dynamics of interaction with a virtual spouse“) beschreibt die erste psychologische Untersuchung in Simoland, welche demonstriert wie intraindividuelle Entwicklung im Interaktionsverhalten untersucht werden kann. An einer Stichprobe von 236 Teilnehmern konnte gezeigt werden, dass sowohl die Beziehungszufriedenheit zum realen Partner, als auch das Intimitätsmotiv der Teilnehmer einen Einfluss auf das Verhalten in der VSU hatten, und somit das virtuelle Verhalten tatsächlich verknüpft ist mit der realen Welt. Während die erste Studie freies Verhalten untersucht hat, wurden in der zweiten Studie theoriegeleitet verschiedene Szenarien hergestellt, welche das Bindungssystem aktivieren sollen. (Kapitel 4: „Transference of adult attachment dynamics to a virtual spouse“). Dadurch konnten an 422 Teilnehmern interindividuelle Unterschiede im Bindungsverhalten als Reaktion auf folgende Szenen gezeigt werden: eine Trennungssituation, eine Konfliktsituation, sowie eine Bedrohungssituation. Die dimensionalen Bindungsstile (Bindungsvermeidung und Bindungsängstlichkeit) korrelierten sinnvoll und signifikant mit dem Verhalten in der VSU, der physikalischen Distanz zwischen Protagonist und Partner/in, sowie Emotionseinschätzungen. Zusammenfasst zeigt diese Dissertation zum ersten Mal, dass Qualitäten der realen Partnerschaft, sowie interne Arbeitsmodelle der Bindung auf virtuelle Agenten übertragen werden. Somit werden neue Wege eröffnet, Beziehungsverhalten und -repräsentationen in virtuellen Szenarien zu untersuchen
