The thesis identifies four modes of action and cooperation of transnational networks of GROs by taking the Tanzania Urban Poor Federation (TUPF), a sub-network of Shack Slum Dweller International (SDI), as an example. Based on the understanding of “interpretive network analysis” (Schindler 2006: pp. 100-101), qualitative and quantitative methodologies of data collection and analysis (expert interviews, member survey, on-site visits of projects, review of TUPF and SDI reports) have been applied in the course of field research. Analysis took place based on a set of criteria regarding the current state of knowledge of typologies, structures, processes, dynamics and preconditions for stable, effective networks. Furthermore, mechanisms for network governance are also taken into account. The selected cases represent a range of issues, applied instruments, different modes of cooperation and scopes of action. Based on the set of criteria, the examination is intended to address questions concerning the relevance of local embeddedness and the capability of the local communities of the TUPF to enter into cross-sectoral and cross-level cooperation. Based on these insights, effects for the scope of action, the empowerment of the actors involved and the development of marginalized settlements are indentified. The case-study research on the basis of the TUPF and SDI verifies the potential of networks for the dissemination of knowledge and the creation of social capital and multidimensional cooperation. However, the analysed modes of action and cooperation develop different degrees of capacities regarding these issues. In this context, the assumed interrelation between the degree of extension of the scope of action and the capability to create multidimensional cooperation in the course of networking activities becomes clear. The cases of the TUPF and SDI show that transnational networks of GROs are able to develop cooperation structures and development strategies involving features of integrated approaches which are spatially and socially embedded in local communities and also benefit from transnational and crosssectoral cooperation. The aspects highlighted above represent a range of potentials and preconditions which turned out to be relevant and important for the activities and processes of local communities within the network. These final results are intended to provide guidance for the development of beneficial structures by governmental actors and development organizations. Furthermore, they should be integrated into a reconsideration of cooperation strategies in the course of urban management processes and development approaches to reduce urban poverty.

In den Sozialwissenschaften profiliert sich derzeit eine disziplinübergreifende Netzwerkforschung, die sich durch eine relationale Theorieperspektive auszeichnet. Die empirische Forschung greift dabei vermehrt auf das Methodenrepertoire der Social Network Analysis (SNA) zurück. Für die Humangeographie kann der soziologische Blick der Netzwerkforschung auf unterschiedliche Weise um „Raumbezüge“ ergänzt und in verschiedenen Forschungsfeldern zur Anwendung gebracht werden. Trotz ihres vielfältigen Potenzials nimmt die SNA in der geographischen Methodenausbildung in Deutschland bisher einen eher untergeordneten Stellenwert ein. Dieses Buch richtet sich an Studentinnen und Studenten, die sich für (humangeographische) empirische Netzwerkforschung interessieren und einen einfachen Einstieg suchen. Es führt verständlich in zentrale Fachbegriffe der SNA und die grundlegenden Funktionen der Analyse-Software UCINet ein. Von der Dateneingabe und -aufbereitung, über die Visualisierung bis hin zu netzwerkanalytischen Berechnungen werden die ersten Schritte vorgestellt und nachvollziehbar erläutert. / Within social sciences and humanities, network research has meanwhile developed into an established cross-disciplinary research perspective, which is based on relational theoretical approaches. Thereby, empirical studies are increasingly drawing on the method repertoire of Social Network Analysis (SNA). For Human Geography, the sociological focus of network research can be complemented by spatial aspects in a variety of ways and applied in several fields of study. Despite its considerable potential, SNA has, to date, played a rather minor role in method training in geographical undergraduate and graduate study programs. This book addresses students interested in (geographical) empirical social network research seeking a basic introduction. It familiarizes the reader with central terms of SNA and with essential functions of the analysis software UCINet. The first steps are presented and explained comprehensibly – from data entry, via visualization to basic network-analytical calculations.

Spatial structures shape human behaviour, or in the words of Bill Hillier – human behaviour does not simply happen in space, it takes on specific spatial forms. How staff interacts in a cellular office differs significantly from the patterns emerging in an open-plan environment. Therefore the dissertation ‘The Space-Organisation Relationship’ analyses how exactly spatial configuration shapes collective behaviours in knowledge-intensive workplace environments. From an extensive literature review it becomes clear that only few insights exist on the relationship between spatial structures and organisational behaviour, despite several decades of intensive research. It is argued that the discourse suffers from disciplinary boundaries; a lack of rigorous research designs; as well as incoherent and outdates studies. Founded on this diagnosis, the dissertation puts up two contrary hypotheses to explain the current state of knowledge: on the one hand it could be argued that hardly any coherent results were found due to the incoherent use of methods and metrics. If this was true it would mean that different organisations would react comparably to similar spatial configurations, if the same methods were used. On the other hand it could be hypothesised that it was inherently impossible to achieve coherent results even with the use of consistent methods, since each space-organisation relationship was unique. To investigate these ideas further, the dissertation employs a combination of qualitative and quantitative methods, embedded within an explorative research design. Both a comparative analysis of different cases and an in-depth study to understand specific organisational behaviours were aimed at by conducting three intensive case studies of knowledge-intensive workplaces: 1) A University, 2) A Research Institute, 3) A Media Company, all of them accommodated in varying spatial structures. Based on a multi-layered analysis of empirical evidence, the dissertation concludes that the relationship between spatial configuration and organisational behaviours can be described by two principles. Firstly, evidence of generic function was found for example between spatial configuration, the placement of attractors, and collective movement flows. These influences are based on general anthropological behaviours and act independently of specific organisational cultures; yet they are rarely found. Secondly, the majority of evidence, especially on more complex organisational constructs such as knowledge flow, organisational cultures and identity suggests that the space-organisation relationship is shaped by the interplay of spatial as well as transpatial solidarities. This means that relationships between people may be formed by either spatial or social proximity. Transpatial relations can overcome distances and are grounded in social solidarities; as such they are not motivated by spatial structures, even though they often mirror spatial order. In essence organisations may react uniquely to comparable spatial configurations. Those two principles – generic function as well as spatial and transpatial solidarities – come in many different forms and jointly shape the character of the space-organisation relationship. This means both hypotheses are true to a degree and apply to different aspects of the space-organisation relationship. / Raumstrukturen beeinflussen menschliches Handeln, oder in den Worten von Bill Hillier – menschliches Verhalten findet nicht nur zufällig im Raum statt, sondern nimmt eine spezifisch räumliche Form an. Das Interaktionsverhalten von Mitarbeitern in einem Zellenbüro beispielsweise unterscheidet sich grundlegend von den Mustern, die sich in einem Großraumbüro entwickeln. Die vorliegende Dissertation „The Space-Organisation Relationship“ beschäftigt sich daher mit der Frage, wie sich die Verbindung zwischen Raumkonfiguration und kollektivem Verhalten einer Organisation in wissensintensiven Arbeitsprozessen gestaltet. Aus der Literatur wird ersichtlich, dass trotz einiger Jahrzehnte intensiver Forschung nur wenige gesicherte Erkenntnisse existieren zur Frage, wie sich Raumstrukturen auf organisationales Verhalten auswirken. Der Diskurs zeigt deutliche Schwächen durch disziplinäre Grenzen, einen Mangel an wissenschaftlich fundierten Studien, sowie inkohärente und teils veraltete Ergebnisse. Um den aktuellen Kenntnisstand zum Verhältnis von Raum und Organisation zu erklären, stellt die Arbeit zwei entgegengesetzte Hypothesen auf: zum einen wird angenommen, dass der Mangel an vergleichenden Studien sowie methodische Schwächen verantwortlich sind für die uneindeutige Beweislage. Sollte dies der Fall sein, müssten in vergleichenden Studien mit gleichem Methodenansatz übereinstimmende Ergebnisse zu finden sein. Dies würde nahe legen, dass jede Organisation als Kollektiv gleich oder zumindest ähnlich auf vergleichbare Raumstrukturen reagiere. Zum anderen wird die entgegengesetzte Hypothese aufgestellt, dass der Charakter und die inhärente Komplexität des Wissensgebietes exakte Aussagen per se unmöglich mache. Dies könnte verifiziert werden, wenn unterschiedliche Organisationen unterschiedlich auf vergleichbare Raumstrukturen reagieren würden, obwohl dieselben wissenschaftlich fundierten Methoden angewendet wurden. Um dies zu überprüfen benutzt die vorliegende Dissertation eine Kombination aus quantitativen und qualitativen Methoden, eingebettet in einen explorativen Forschungsaufbau, um sowohl vergleichende Analysen zwischen Organisationen durchführen, als auch tiefergehende Interpretationen zu spezifischem organisationalem Verhalten anstellen zu können. Die Arbeit stützt sich auf drei intensive Fallstudien unterschiedlicher wissensintensiver Tätigkeiten – einer Universität, einem Forschungsinstitut, und einem Medienunternehmen, die in jeweils unterschiedlichen räumlichen Strukturen agieren (Zellenbüros, Gruppenbüros, Kombibüros, Großraumbüros). Aufbauend auf der vielschichtigen Analyse empirischer Ergebnisse kommt die Dissertation zur Erkenntnis, dass sich das Verhältnis zwischen Raumkonfiguration und organisationalem Verhalten durch zwei Prinzipien beschreiben lässt. Einerseits sind so genannte generische Einflüsse festzustellen, zum Beispiel zwischen Raumkonfiguration, der Platzierung von Ressourcen und Bewegungsmustern. Diese generischen Einflüsse gehen auf grundlegende menschliche Verhaltensmuster zurück und agieren im Wesentlichen unabhängig von spezifischen Organisationskulturen. Allerdings sind sie selten, und nur wenige Faktoren können als generisch angenommen werden. Andererseits ist die überwiegende Mehrheit der Raum-Organisations-Beziehungen bestimmt vom Wechsel zwischen räumlicher und so genannter trans-räumlicher Solidarität, das heißt Beziehungen zwischen Individuen können sich entweder auf räumliche oder soziale Nähe stützen. Trans-räumliche Beziehungen, die sich aufgrund von sozialer Nähe entfalten können beispielsweise Entfernungen überwinden, und sind daher in erster Linie nicht räumlich motiviert, auch wenn sie sich oft in räumlichen Ordnungen widerspiegeln. Diese beiden Prinzipien – generische Einflüsse sowie räumliche und trans-räumliche Funktionsweisen – treten in vielschichtigen Formen auf und bestimmen den Charakter des Verhältnisses zwischen Raum und Organisation. Damit treffen beide der aufgestellten Hypothesen auf unterschiedliche Aspekte und Teilbereiche des Raum-Organisations-Zusammenhangs zu.

The thesis identifies four modes of action and cooperation of transnational networks of GROs by taking the Tanzania Urban Poor Federation (TUPF), a sub-network of Shack Slum Dweller International (SDI), as an example. Based on the understanding of “interpretive network analysis” (Schindler 2006: pp. 100-101), qualitative and quantitative methodologies of data collection and analysis (expert interviews, member survey, on-site visits of projects, review of TUPF and SDI reports) have been applied in the course of field research. Analysis took place based on a set of criteria regarding the current state of knowledge of typologies, structures, processes, dynamics and preconditions for stable, effective networks. Furthermore, mechanisms for network governance are also taken into account. The selected cases represent a range of issues, applied instruments, different modes of cooperation and scopes of action. Based on the set of criteria, the examination is intended to address questions concerning the relevance of local embeddedness and the capability of the local communities of the TUPF to enter into cross-sectoral and cross-level cooperation. Based on these insights, effects for the scope of action, the empowerment of the actors involved and the development of marginalized settlements are indentified. The case-study research on the basis of the TUPF and SDI verifies the potential of networks for the dissemination of knowledge and the creation of social capital and multidimensional cooperation. However, the analysed modes of action and cooperation develop different degrees of capacities regarding these issues. In this context, the assumed interrelation between the degree of extension of the scope of action and the capability to create multidimensional cooperation in the course of networking activities becomes clear. The cases of the TUPF and SDI show that transnational networks of GROs are able to develop cooperation structures and development strategies involving features of integrated approaches which are spatially and socially embedded in local communities and also benefit from transnational and crosssectoral cooperation. The aspects highlighted above represent a range of potentials and preconditions which turned out to be relevant and important for the activities and processes of local communities within the network. These final results are intended to provide guidance for the development of beneficial structures by governmental actors and development organizations. Furthermore, they should be integrated into a reconsideration of cooperation strategies in the course of urban management processes and development approaches to reduce urban poverty.

Die unkontrollierte menschliche Entwicklung beeinflusst alle Aspekte der Interaktionen und Prozesse von Ökosystemen (Ökosystemfunktionen), einschließlich derjenigen, die für Menschen von Nutzen sind und sein werden (Ökosystemdienstleistungen). In dieser Arbeit habe ich einen neuen analytischen Ansatz entwickelt, der auf der Netzwerkanalyse basiert, um die Strukturdynamik von Ökosystemen in der Tiefe zu untersuchen. Ich habe diesen Ansatz validiert, indem ich den gut untersuchten Fossilienbestand großer Säugetiere der Iberischen Halbinsel während der letzten 21 Ma verwendet habe. Das funktionelle System durchlief lange Perioden der Stabilität, unterbrochen von einer schnellen Reorganisation, die einen neuen stabilen Zustand fand. Hohe funktionelle Diversität und Reichhaltigkeit befeuert mit der Zeit zunehmende Belastbarkeit der Funktionsstruktur (Versicherungseffekt). Dann verwende ich eine Kombination aus funktionaler Diversität (fdiv) und Netzwerkanalyse über einen beispiellosen Datensatz von großen Pflanzenfressern weltweit, der sich über die letzten 65 Millionen Jahre erstreckt. Es gab einen anfänglichen Trend zur Zunahme der funktionellen Diversität, vermittelt durch einen Nettogewinn an funktionellem Reichtum, der 20 Ma erreichte, wahrscheinlich angeheizt durch die Bildung der sogenannten Gomphotherium-Landbrücke. Danach blieb der fdiv des Systems hoch und erreichte das maximale Niveau von 10 Ma, als das System viele Arten mit ähnlichen ökologischen Rollen (funktionelle Sättigung) angesammelt hatte, was letztendlich ihren funktionellen Zusammenbruch provozierte. Danach zeigte das System eine schnellere ökologische Verarmung, die während des Beginns der pleistozänen Vergletscherung um etwa 2,5 Ma zunahm. In Bezug auf die funktionelle Struktur stellen wir fest, dass känozoische große Pflanzenfressergemeinschaften lange Perioden der Stabilität durchlebten, gefolgt von der Reorganisation ihrer funktionellen Struktur in neue stabile Zustände (um 20 und 10 Ma). / Uncontrolled human development is affecting all aspects of ecosystems' interactions and processes (ecosystem functioning), including those that are, and will be, beneficial to people (ecosystem services). In this thesis I developed a new analytical approach based on network analysis to study deep time ecosystem structure dynamics. I validated this approach using the well studied large mammal fossil record of the Iberian Peninsula during the last 21 Ma. The functional system underwent long periods of stability punctuated by a rapid reorganization finding a new stable state. High functional diversity and richness fueled the time increasing resilience of the functional structure (insurance effect). Then, I use a combination of functional diversity (fdiv) and network analysis over an unprecedented dataset of worldwide large herbivores spanning the last 65 Myrs. There was an initial trend towards the increment of functional diversity, mediated by a net gain in functional richness that peaked 20 Ma, likely fueled by the formation of the so-called Gomphotherium land bridge. Thereafter, the system’s fdiv remained high reaching the maximum level 10 Ma, when the system had accumulated many species with similar ecological roles (functional saturation), which ultimately provoked their functional collapse. After that, the system showed a faster ecological impoverishment increasing around 2.5 Ma during the beginning of Pleistocene glaciations. Regarding the functional structure, we find that Cenozoic large herbivore communities experienced long periods of stability followed by the reorganization of their functional structure in new stable states (around 20 and 10 Ma).

Mouse embryonic stem cells (mESCs) can be maintained in a proliferative and undifferentiated state over many passages (self-renewal) while retaining the potential to give rise to every cell type of the organism (pluripotency). Autocrine FGF4/Erk signalling has been identified as a major stimulus for fate decisions and lineage commitment in these cells. Recent findings on serum-free culture conditions with specific inhibitors (known as 2i) demonstrate that the inhibition of this pathway reduces transcription factor heterogeneity and is vital to maintain ground state pluripotency of mESCs. We suggest a novel mathematical model to explicitly integrate FGF4/Erk signalling into an interaction network of key pluripotency factors (namely Oct4, Sox2, Nanog and Rex1). The envisaged model allows to explore whether and how proposed mechanisms and feedback regulations can account for different expression patterns in mESC cultures. We demonstrate that an FGF4/Erk-mediated negative feedback is sufficient to induce molecular heterogeneity with respect to Nanog and Rex1 expression and thus critically regulates the propensity for differentiation and the loss of pluripotency. Furthermore, we compare simulation results on the transcription factor dynamics in different self-renewing states and during differentiation with experimental data on a Rex1GFPd2 reporter cell line using flow cytometry and qRT-PCR measurements. Concluding from our results we argue that interaction between FGF4/Erk signalling and Nanog expression qualifies as a key mechanism to manipulate mESC pluripotency. In particular, we infer that ground state pluripotency under 2i is achieved by shifting stable expression pattern of Nanog from a bistable into a monostable regulation impeding stochastic state transitions. Furthermore, we derive testable predictions on altering the degree of Nanog heterogeneity and on the frequency of state transitions in LIF/serum conditions to challenge our model assumptions.

Die vorliegende Arbeit vertritt die These, dass kein direkter Zusammenhang zwischen dem Arbeitsklima und der allgemeinen Arbeitszufriedenheit besteht, sondern dass er durch soziale Vergleichsprozesse vermittelt ist. Das Arbeitsklima ist Gegenstand und Moderator sozialer Vergleiche, aus denen Arbeitszufriedenheit resultiert. Das Arbeitsklima beeinflusst damit zwar den Entstehungsprozess von Arbeitszufriedenheit, aber nicht dessen Ausmaß. Von affektiven und regulativen Klimadimensionen gehen unterschiedliche Wirkungsmechanismen aus. Überschreiten soziale Vergleiche die Organisationsgrenze, ändert sich die Logik der Entstehung von Arbeitszufriedenheit.
