An increasing number of companies report that eco-sustainable initiatives have a positive impact on firms’ economic performance and concurrently allow the combination of social and commercial goals by optimizing environmental and economic decisions simultaneously. These initiatives are considered an integral part of organizational sustainability transformations, which are a special case of multilayered, complex organizational change efforts that relate to environmental, organizational, and individual factors. Institutional logics and information systems (IS) have shown to be two important perspectives from which to explore mechanisms and processes central to organizational sustainability transformations. Institutional logics offer a unique perspective to investigate organizational change for sustainability because they provide a new approach to organizational change that incorporates macro structures, culture, and agency to explain how actions are enabled or constrained. It thus allows for insights into the complex and miscellaneous interplay of external and internal determinants that govern organizational transformation processes towards sustainability. By providing insights into institutional changes of practice and behaviors, an institutional logic perspective allows for a detailed analysis of organizational transformations. Within these change processes, IS have shown to be an efficient and pervasive tool to leverage sustainability by integrating human and technological factors. Since IS have become a key resource for the encouragement of organizational sustainability transformations, adopting an IS perspective allows for an understanding of mechanisms and processes that enable IS to foster sustainability in organizations. Thus, this dissertation draws on four studies by investigateing an institutional logic perspective as well as an IS perspective to explore organizational sustainability transformations and facilitate an in-depth understanding of organizational, human, and technological factors that encourage sustainability in organizational transformations.
Information has a particular importance in online purchase decision processes. As opposed to consumers in online markets, consumers in online markets cannot inspect the physical product to evaluate it and reduce their perceived risk. Hence, consumers in online markets are dependent upon the information that they can gather about a product in which they are interested. Therefore, they have two primary sources of information: Product descriptions and customer reviews. Both sources affect consumers’ purchase decision processes and hence have an economic impact for consumers, shop providers and manufacturers. It is important to know how these sources of information influence a customer’s online purchase decision and how to extract the relevant information.
To examine these research objectives, several studies applying different methodological approaches have been conducted. The results are presented in this dissertation.
In the age of globalization, exponential growth and digitalization, organizations need to make faster decisions, as well as continually innovate and adapt to changing customer needs to ensure their long-term competitiveness (Kammerlander et al. 2018; Magnusson and Martini 2008). Notably, large and established companies find it difficult to keep up with start-ups and smaller companies as well as with digital transformation (Christensen et al. 2015).
Thus, organizations are increasingly providing their workforce with Enterprise Social Networks (ESNs) as intra-organizational social software platforms.
Although ESNs hold great promises for organizations and their employees (Mäntymäki and Riemer 2016), most ESN initiatives fail to leverage the intended benefits (Chin et al. 2015). This dissertation seeks to open up the black box behind this seemingly paradoxical relationship.
It comprises four studies that are guided by the following research questions:
R 1: How do different types of users (posters and lurkers) differ in their motivations for participating in ESNs? (= Paper 1)
R 2: Why do employees deliberately not use the ESN? (= Paper 2)
R 3: How can ESNs be successfully implemented and improved to overcome the challenges perceived by employees? (= Paper 3)
R 4: Does ESN usage impact on individual task performance? And how can ESNs be used effectively to increase performance outcomes? (= Paper 4)
Overall, the four studies contribute to a better understanding of the non-adoption phenomenon of ESNs, provide rich insights on employees’ underlying reasons and challenges regarding ESN usage, while underscoring the potential value of ESNs.
Die vorliegende publikationsbasierte Dissertationsschrift beschäftigt sich mit dem Phänomen der „Sicherheitsbedrohungen“ aus europäischer und US-amerikanischer Perspektive. Sie bewegt sich damit auf dem Gebiet der Security Studies. Dabei geht die Arbeit von einem erweiterten Verständnis von Sicherheit aus, das über das traditionell militärische Sicherheitsverständnis hinausgeht. Bedrohungen können demzufolge aus verschiedensten Situationen hervorgehen – unter anderem aus Finanzkrisen oder transnationalem Terrorismus. Nichtsdestotrotz stehen auch für die New Security Studies (mit ihrem so verstandenen erweiterten Sicherheitsbegriff) ebenso jene Bedrohungsszenarien im Fokus, die aus zwischenstaatlichen Konflikten resultieren, wie beispielsweise aus dem Ukraine-Russland Konflikt der vergangenen Jahre.
Im Rahmen dieser Arbeit werden die folgenden, zentralen Forschungsziele verfolgt: das Gewinnen von theoretisch-fundierten empirischen Erkenntnissen mit Blick auf ausgewählte Problemfelder der europäischen und US-amerikanischen Außen- und Sicherheitspolitik und mit Blick auf die transatlantischen Beziehungen (1) sowie die Erweiterung und Vertiefung der Securitization-Theorie und ihrer Anwendungsfelder in der Internationalen Politik (2).
This cumulative thesis consists of six single contributions: five independent essays and an introductory chapter. All of the conributions have been published or accepted for publication. The overarching scope of these essays is to analyze different factors accounting for the stability of post-Soviet authoritarian regimes and the obstacles, which Western democracy promoters can face when dealing with autocrats. The starting point for these enquiries has been the striking inability of Western democracies and in particular of the European Union to encourage and to assist political transformation in the majority of the post-Soviet republics.
In this thesis I empirically assess a wide range of constraints faced by different types of entrepreneurs in developing countries and the effectiveness of different policy interventions aimed at removing them. Thereby, the thesis contributes to the growing literature on enterprises and entrepreneurial activities in developing countries, by producing valuable evidence on which are the constraints faced by which types of entrepreneurs in starting, surviving, and growing, as well as on which interventions work, and for whom. The thesis hence provides important insights for policy formulation aimed at inclusive growth.
It consists of three self-contained papers, which put different emphasis on three different areas in which important research gaps remain. The first paper, which is presented in chapter 2, focuses on interventions aimed at removing firm-level shocks. It consists of a systematic review of evaluations of targeted programs and broader policies that intend to promote micro-, small and medium-sized enterprises (MSMEs) in developing countries, and assesses which of these interventions are effective in creating jobs. The paper presented in chapter 3 considers death of small, mainly one-person and household businesses. Together with my co-author, I collated panel data on more than 14,000 small firms from 16 firm panel surveys conducted in 12 developing countries. We use this unique panel dataset to provide answers to the following questions: What is the rate of firm death over different horizons? Which firms are more likely to die? Why do they die and what happens afterwards? In chapter 4, I take a closer look at household-level shocks and non-separability between the household and the firm, and assess whether extending health insurance to previously uninsured households leads to increased investment in productive activities, by assessing the impact of a large national health insurance scheme, the Mexican Seguro Popular, on investment in productive agricultural and non-agricultural assets and activities in rural areas. Using panel data from the Mexican rural evaluation surveys of the Oportunidades cash transfer program, I estimate the effect of the program on out-of-pocket health care expenditures and productive assets and account for possible self-selection of households into the program, using difference-in-differences estimation, as well as a propensity score matched difference-in-differences specification.
Der Binnentourismus in den ASEAN-Staaten wird an Hand von vorhandenen statistischen Daten untersucht. Durch Befragungen thailändischer Binnentouristen wird darüber hinaus die Datenerhebung ausgeweitet, um die vorhandenen statistischen Daten zu ergänzen und zu verifizieren. Hierbei wird insbesonders untersucht, in wieweit der Binnentourismus in den Ländern wahrgenommen wird, welche Bevölkerungsgruppen sich daran beteiligen, welche Interessen sie dabei verfolgen und welche Auswirkungen der Binnentourismus in physiognomischer und sozio-kultureller Hinsicht mit sich bringt.
This study examines the dynamics which lead to revitalization of everyday life in the public spaces of Cagayan de Oro, a medium-sized urban center in Northern Mindanao, the Philippines. By employing the oriental philosophies together with western thoughts such as Henri Lefebvre, Alain Touraine and Jürgen Habermas, this study elucidates that the core of perceived, lived and conceived spaces is ‘the Subject.’ Once the Subject utilizes the public sphere to instill social action, social space is ultimately produced. Hawkers, grassroots environmental activists, street readers and artists are the social Subjects who partake in the vibrancy of public spaces. The social Subjects utilize public spaces as venues of social transformation. Thus, this study argues that the social Subjects’ role in democratic process lead to inclusivity of the marginalized sector in the public spaces of the city.
"Die Umsetzung eines inklusiven Bildungswesens ist Auftrag der Übereinkunft zum Schutz der Rechte von Menschen mit Behinderungen (UN-BRK, Art. 24) und mit der Ratifizierung durch die Bundesregierung in Deutschland seit 2009 staatliche Verpflichtung und nationales Recht.
Die Debatte, wie ein inklusives Schulsystem umzusetzen sei, wird von diversen Standpunkten aus geführt. Für die vorliegende Fragestellung ist der didaktische Ansatz Feusers (1995 u.a.) in besonderer Weise relevant: der "gemeinsame Gegenstand" ist didaktisches Fundamentum sowie Qualitätskriterium inklusiven Lernens. Ebenfalls ist das Verständnis Muths (2002 u.a.), die Verwirklichung eines "integrativen Schulwesens" als primär demokratische Aufgabe zu verstehen, ein als besonders relevant zu bewertender Ansatz für die vorliegende Arbeit (s.u.). Die von Rolff (2010 und 2016) beschriebenen Interdependenzen von (Schul-) Entwicklungsprozessen, auch und gerade zwischen den Institutionen (s.u.) gilt es ebenfalls zu berücksichtigen.

Die (erste) Waldorfschule wurde im Jahr 1919 in der Folge der sozialreformerischen Bewegung der "Dreigliederung des sozialen Organismus" begründet. Basis der heute ca. 250 in Deutschland arbeitenden Waldorfschulen bildet nach wie vor das umfassende Menschenverständnis der Anthropologie Rudolf Steiners, welche sich in der "Allgemeinen Menschenkunde als Grundlage der Pädagogik" (Steiner 1992) grundlegend und erstmalig konkretisierte. Die pädagogischen Schriften und Vorträge Steiners verstehen den Menschen als sich entwickelndes Wesen in einem umfassenden Sinn, (schulische) Pädagogik somit als Unterstützung der kindlichen Entwicklung. Eine Differenzierung oder Einschränkung der grundsätzlich bestehenden Entwicklungsfähigkeit wird nicht vorgenommen. Als Gesamtschule hat die Waldorfschule daher von Beginn an Kinder mit unterschiedlichsten Begabungen, Möglichkeiten und Grenzen aufgenommen und pädagogisch begleitet . Die Begriffe Individualität, Diversität und Heterogenität bilden die anthropologische Basis pädagogischen Handelns an Waldorfschulen und beinhalten damit grundsätzlich das Potential inklusiven Unterrichts bzw. inklusiver (Schul-) Entwicklungen.
Die waldorfpädagogische Praxis und die zugrundeliegende Theorie wurden bisher in einem relativ geringen Maß wissenschaftlich zur Kenntnis genommen bzw. diskursiv diskutiert . Um die Potenziale einer sich auch aktuell als zeitgemäß verstehenden Pädagogik für das traditionelle "Regelschul-System" bzw. Innovationen daselbst fruchtbar zu machen, bedarf es weiterer und erneuter sowohl theoretischer (erziehungswissenschaftlicher und didaktischer) als auch praktischer Auseinandersetzung.

Die für die Entwicklung der jeweiligen pädagogischen Theoriebildung und Praxis (ausgehend von Waldorfpädagogik in Theorie und schulischer Praxis, inklusionspädagogische Fragestellungen und Forschungsergebnisse einbeziehend) notwendigen bzw. möglichen grundlegenden Bedingungen werden exemplarisch analysiert und benannt, um sie für einen Gesamt-Reformprozess verfügbar zu machen. Konkret geht es um das Potential der Waldorfpädagogik (in Theoriebildung und schulischer Praxis) für zu entwickelnde Formen inklusiven Lernens."
Due to the need for fast and energy-efficient accesses to growing amounts of data, the share and number of embedded memories inside modern microchips has been continuously increasing within the last years. Since embedded memories have the highest integration density of a fabrication technology they pose special test challenges due to complex manufacturing defects as well as strong transistor aging phenomena. This necessitates efficient methods for detecting more subtle defects while keeping test costs low. This work presents novel methods and techniques for improving the efficiency of embedded memory manufacturing tests. The proposed methods are demonstrated in an industrial setting based on production-proven transistor, memory as well as chip models and their benefits over the current state-of-the art is worked out.
