The impact of urban development on local residents in the urban periphery oscillates between processes of empowerment and processes of marginalization as well as between state-controlled order and decentralized self-organization. Consequently local authorities, including urban planners and local residents need to negotiate their respective roles in the production and usage of urban space defined by transition, transformation and ambiguity. Therefore, this work examines the underlying patterns, interactions and structures which define the negotiation of state-society relations in the framework of a porous peri-urban landscape in Vietnam’s secondary cities.
In Chapter 1, peri-urban areas are defined as space of transformation where pattern of rural land use are intertwined with pattern of urban land use to create an urban-rural interface with blurred boundaries. The main characteristic of the spatial pattern in Tam Kỳ and Buôn Ma Thuột is rooted urban porosity leading to the spatial intertwining of rural, peri-urban and urban spaces. The emerging urban landscape can be defined as peri-urban city. Three main themes define this peri-urban city beyond porosity: (1) processes of transformation creating the peri-urban city, (2) networks of power and control as means to adapt to these transformations and (3) mobility as prerequisite for ability to benefit from the changing landscape in peri-urban cities.
Chapter 2 describes how state authorities, urban planners and private investors at the local level in Tam Kỳ and Buôn Ma Thuột use porous space to reproduce the city based on their aspirations. This leads to a cargo cult urbanism, where urban planning is rooted in future aspirations for the city. Plans and construction efforts reference the image of a modern urban future and produce the image of a city, which does not exists in the real urban space of Tam Kỳ and Buôn Ma Thuột. In the meantime, practices based in peri-urban space are often contradictory to the official aspirations of local state authorities
Chapter 3 explores this emerging divergence between the aspired urban space by the state and the reality of urban space rooted in material and social porosity. Traditional, newly accessible and environmental porosity provide an array of accessible space which transforms the peri-urban city into a social arena of encounters and interaction. Consequently, porosity enables local residents to maintain urban space as commons. This counters the push towards the privatization of urban space by state and private actors and creates multiple aspirations for the urban future.
Rooted in urban space as commons, porosity enables the usage of peri-urban space as spaces of resistance as discussed in Chapter 4. Mobility and interaction are means of reproduction in the porous ambiguity of urban materiality but also become means of everyday resistance. The emerging spatialities of emancipation provide opportunities for an emerging urban citizenship. Urban materiality and urban citizenship have a mutually constitutive relationship.
Looking at what Geographers do – Empirische Beiträge zur Wissenschaftsbeobachtung in der Geographie
(2022)
The research interest of this doctoral thesis addresses the academic practice of German-speaking geography. It is thus both a "meta-geographical" thesis in the sense of disciplinary science research and a social-geographical thesis that examines how scientists interact with each other as social actors in the academic field. In this dissertation, a total of five scientific articles are presented. All contributions examine German-language geography from a scientometric perspective. The unifying aspect of this work is not the one major research question, but the research object and the methodological perspective taken. The work is divided into two parts: Based on bibliometric data research and network analysis, the first part is dealing with the question of the unity of geography (papers 1-3) and paradigm evolution exemplified by the new cultural geography (paper 4). The second part deals with gender inequalities in geography. Here, one scientific article (paper 5) is presented and put into context. The focus is on gender differences in scientific practices at geographic conferences.
Sterblichkeit und Erinnerung
(2022)
Wer von Erinnerung spricht, darf vom Tod nicht schweigen. Das Bewahren von Wissen, von Ereignissen, aber auch von Empfindungen usw. gewinnt gerade durch die prinzipielle Vergänglichkeit des menschlichen Handelns seine Bedeutung. Die Erinnerung an die Lebenswelt Verstorbener ist deshalb keine authentische Dokumentation, sondern durch gesellschaftlich tradierte Konzepte des Erinnerns (oder auch Nicht-Erinnerns) vorgeprägt. Vor diesem Hintergrund setzen sich die Beiträge dieses Bandes mit dem Verhältnis von Erinnerung und Vergangenheitsbezug im Spannungsfeld von Sterblichkeit, Tod und Gesellschaft auseinander. Mit Beiträgen von Thorsten Benkel, Ekkehard Coenen, Oliver Dimbath, Jan Ferdinand, Carsten Heinze, Matthias Meitzler, Christoph Nienhaus, Melanie Pierburg, Sarah Peuten, Leonie Schmickler, Laura Völkle, Lara Weiss und Nico Wettmann.

Kann die Gesellschaft die hermeneutische Ungerechtigkeit gegenüber Menschen mit Lernbehinderungen abmildern? Wie stellen sich die europäischen Theater dieser Herausforderung? Wie können Künstler mit Lernbehinderungen "eine Stimme haben"? Der vorliegende Band sucht in theoretischen Ansätzen und in Interviews mit Regisseuren nach Antworten auf diese Fragen.
Sichtbarkeitsprobleme, wie das Folgende, gehören zu den grundlegenden Problemen der algorithmischen Geometrie: Berechne zu einem einfachen Polygon, dem sogenannten Kanal, und zu einem darin enthaltenen Punkt die von diesem Punkt aus sichtbare Punktmenge. Dabei ist ein Punkt von einem anderen Punkt aus sichtbar, wenn deren Verbindungsstrecke den Kanal nicht verlässt. Wir wollen uns in dieser Arbeit mit zirkulärer Sichtbarkeit beschäftigen. Zur Verbindung zweier Punkte sind dann nicht nur Strecken, sondern auch Kreisbögen zulässig. Außerdem betrachten wir als Ausgangspunkt dieser sogenannten Sichtbarkeitskreisbögen und -strecken eine Kante des Kanals anstatt eines einzelnen Punkts. Konkret liefert diese Arbeit einen Beitrag zur numerisch robusten Bestimmung der zirkulären Sichtbarkeitsmenge ausgehend von einer Kante des Kanals.
Hierfür wird in dieser Arbeit ein Algorithmus vorgestellt, mit dem für einen gegebenen Punkt festgestellt werden kann, ob dieser von der Startkante aus sichtbar ist. Im Fall eines sichtbaren Punkts wird ein Sichtbarkeitskreisbogen berechnet, der zwei Kanalberührungen besitzt. Damit kann der Algorithmus bei geeigneter Wahl des zu untersuchenden Punkts – der als dritte Kanalberührung fungiert – direkt zur Berechnung von sogenannten Grenzkreisbögen der Sichtbarkeitsmenge benutzt werden. Diese definieren den Rand der zirkulären Sichtbarkeitsmenge und zeichnen sich dadurch aus, dass sie vom Kanal dreimal abwechselnd von links und von rechts berührt werden.
Der beschriebene Algorithmus basiert auf der Untersuchung derjenigen Kreisbögen, die zwar nicht notwendigerweise vollständig im Kanal liegen, aber die Startkante mit dem Punkt verbinden, dessen Sichtbarkeit bestimmt werden soll. Insbesondere werden dabei die Bereiche untersucht, in denen der jeweilige Kreisbogen den Kanal
verlässt, die sogenannten Verletzungen. Da die „Schwere“ einer solchen Verletzung quantifizierbar ist, wird ein iteratives Vorgehen ermöglicht. Dabei wird der Kreisbogen iterativ so verändert, dass dieser bei gleichem Endpunkt den Kanal immer „weniger verlässt“. Ist der Endpunkt und damit der zu untersuchende Punkt nicht sichtbar, wird im Laufe des Algorithmus festgestellt, dass keine derartige Verbesserung möglich ist. Der vorgestellte Algorithmus ist numerisch robust, einfach umzusetzen und besitzt eine in der Anzahl der Kanalecken lineare Laufzeit.
Data-driven decision-making and data-intensive research are becoming prevalent in many sectors of modern society, i.e. healthcare, politics, business, and entertainment. During the COVID-19 pandemic, huge amounts of educational data and new types of evidence were generated through various online platforms, digital tools, and communication applications. Meanwhile, it is acknowledged that educa-tion lacks computational infrastructure and human capacity to fully exploit the potential of big data. This paper explores the use of Learning Analytics (LA) in higher education for measurement purposes. Four main LA functions in the assessment are outlined: (a) monitoring and analysis, (b) automated feedback, (c) prediction, prevention, and intervention, and (d) new forms of assessment. The paper con-cludes by discussing the challenges of adopting and upscaling LA as well as the implications for instructors in higher education.
After the enactment of the GDPR in 2018, many companies were forced to rethink their privacy management in order to comply with the new legal framework. These changes mostly affect the Controller to achieve GDPR-compliant privacy policies and management.However, measures to give users a better understanding of privacy, which is essential to generate legitimate interest in the Controller, are often skipped. We recommend addressing this issue by the usage of privacy preference languages, whereas users define rules regarding their preferences for privacy handling. In the literature, preference languages only work with their corresponding privacy language, which limits their applicability. In this paper, we propose the ConTra preference language, which we envision to support users during privacy policy negotiation while meeting current technical and legal requirements. Therefore, ConTra preferences are defined showing its expressiveness, extensibility, and applicability in resource-limited IoT scenarios. In addition, we introduce a generic approach which provides privacy language compatibility for unified preference matching.
Die vorliegende Dissertation behandelt die Qualität von Prozessmodellen.
Vor diesem Hintergrund haben Experteninterviews mit Forschungs- und Praxispartnern zur Entwicklung und Evaluierung eines Ordnungsrahmens zur Qualitätsbestimmung von Prozessmodellen beigetragen.
Die Ergebnisse zeigen, dass unter anderem die Einsatzzwecke der Prozessmodelle sowie die mit den Prozessmodellen in Berührung kommenden Personengruppen differenziert betrachtet werden müssen, um Auswirkungen auf die Prozessmodellqualität untersuchen zu können.
My study examines how the configuration of the capitalist frontier through extractivism shapes ethnicity, gender, and intersectionality in the areas surrounding a nickel mine in Sorowako (East Luwu District, South Sulawesi), logging and coal mining along the Lalang River (Murung Raya District, Central Kalimantan) Indonesia. The colonial frontier intersects with the capitalist frontier and provides the circumstances for its formation. The colonial restrictions, religions, commodities, the imposition of labor discipline, and political changes have molded ethnic identities and relationships with nature. Furthermore, using autoethnography and Feminist Political Ecology, I combine my experiences as a woman academic-activist with the experiences of the people in my research area. I identify how communities and individuals interact with the multiple-frontier in everyday life by defining the configuration of the frontier from above and below. Thus, my dissertation contributes to understanding how I, the community, and the capitalist frontier landscape are contained and can potentially transform into multidimensional resistance. I develop a link between the body as the interior frontier and the extractive landscape to be transformed into a perspective of “Tubuh-tanah air” as a future arena of engagement and resistance to extractivism.
This dissertation examines the overarching research question of how the suppliers’ brand management in the form of brand identity, brand culture, and brand essence influences buyer-seller relationships in three independent essays.
In Essay 1, I address the structure, capabilities, and outcomes of brand identity from a supplier perspective. Through qualitative interviews with suppliers, I examine how widespread the concept of brand identity is in practice and what exactly practitioners understand by it. Going further, I look at what capabilities and conditions are necessary for brand identity to be successful and what outcomes suppliers hope to achieve. Using an Information-Display-Matrix (IDM) test and a sample of Master of Business Administration (MBA) students, I examine the relevance of brand functions in more detail.
In Essay 2, I use a dyadic dataset with matched buyer-seller dyads to examine the causes and effects of perceptual congruence and incongruence of brand culture strength on the buyer-seller relationship, while considering relationship-specific investments and interaction mechanisms as moderating effects. I show that congruence and incongruence have different effects on customer loyalty and price sensitivity and that these are strongly context-dependent.
In Essay 3, I deal with brand essence strength interactions and their effects on the buyer-seller relationship. I use a dyadic dataset with matched buyer-seller dyads to show how brand essence strength influences customer loyalty and customer profitability, and how it interacts with key customer attitudes and other important buyer-seller relationship closeness indicators.
This dissertation makes a significant contribution to the literature on brand identity, brand culture, and brand essence in buyer-seller relationships. Furthermore, my dissertation offers practical implications for managers at B2B suppliers who (re)shape their brand management with a focus on the inner parts of the brand.
