Der hieraus entstandene Begriff E-Government wurde in der Folge aus den unterschiedlichsten technischen, politischen und semantischen Blickrichtungen beleuchtet. Die vorliegende Arbeit konzentriert sich dabei auf zwei Schwerpunktthemen: • Das erste Schwerpunktthema behandelt den Entwurf eines hierarchischen Architekturmodells, f{\"u}r welches sieben hierarchische Schichten identifiziert werden k{\"o}nnen. Diese erscheinen notwendig, aber auch hinreichend, um den allgemeinen Fall zu beschreiben. Den Hintergrund hierf{\"u}r liefert die langj{\"a}hrige Prozess- und Verwaltungserfahrung als Leiter der EDV-Abteilung der Stadtverwaltung Landshut, eine kreisfreie Stadt mit rund 69.000 Einwohnern im Nordosten von M{\"u}nchen. Sie steht als Repr{\"a}sentant f{\"u}r viele Verwaltungsvorg{\"a}nge in der Bundesrepublik Deutschland und ist dennoch als Analyseobjekt in der Gesamtkomplexit{\"a}t und Prozessquantit{\"a}t {\"u}berschaubar. Somit k{\"o}nnen aus der Analyse s{\"a}mtlicher Kernabl{\"a}ufe statische und dynamische Strukturen extrahiert und abstrakt modelliert werden. Die Schwerpunkte liegen in der Darstellung der vorhandenen Bedienabl{\"a}ufe in einer Kommune. Die Transformation der Bedienanforderung in einem hierarchischen System, die Darstellung der Kontroll- und der Operationszust{\"a}nde in allen Schichten wie auch die Strategie der Fehlererkennung und Fehlerbehebung schaffen eine transparente Basis f{\"u}r umfassende Restrukturierungen und Optimierungen.

Dies erfolgt auf Basis einer kontinuierlichen Betriebsdatenerfassung mit aufwendiger Vorverarbeitung zur Extrahierung mathematisch beschreibbarer Wahrscheinlichkeitsverteilungen.

  abstract  = {Discourse production is crucial for communicative success and is in the core of aphasia assessment and treatment. Coherence differentiates discourse from a series of utterances/sentences; it is internal unity and connectedness, and, as such, perhaps the most inherent property of discourse. It is unclear whether people with aphasia, who experience various language production difficulties, preserve the ability to produce coherent discourse. A more general question of how coherence is established and represented linguistically has been addressed in the literature, yet remains unanswered. This dissertation presents an investigation of discourse production in aphasia and the linguistic mechanisms of establishing coherence.},

  abstract  = {Since the 1960ies, Germany has been host to a large Turkish immigrant community. While migrant communities often shift to the majority language over the course of time, Turkish is a very vital minority language in Germany and bilingualism in this community is an obvious fact which has been subject to several studies. The main focus usually is on German, the second language (L2) of these speakers (e.g. Hinnenkamp 2000, Keim 2001, Auer 2003, Cindark \& Aslan (2004), Kern \& Selting 2006, Selting 2009, Kern 2013). Research on the Turkish spoken by Turkish bilinguals has also attracted attention although to a lesser extend mainly in the framework of so called heritage language research (cf. Polinski 2011). Bilingual Turkish has been investigated under the perspective of code-switching and codemixing (e.g. Kallmeyer \& Keim 2003, Keim 2003, 2004, Keim \& Cindark 2003, Hinnenkamp 2003, 2005, 2008, Dirim \& Auer 2004), and with respect to changes in the morphologic, the syntactic and the orthographic system (e.g. Rehbein \& Karako{\c{c}} 2004, Schroeder 2007). Attention to the changes in the prosodic system of bilingual Turkish on the other side has been exceptional so far (Queen 2001, 2006). With the present dissertation, I provide a study on contact induced linguistic changes on the prosodic level in the Turkish heritage language of adult early German-Turkish bilinguals. It describes structural changes in the L1 Turkish intonation of yes/no questions of a representative sample of bilingual Turkish speakers. All speakers share a similar sociolinguistic background. All acquired Turkish as their first language from their families and the majority language German as an early L2 at latest in the kinder garden by the age of 3. A study of changes in bilingual varieties requires a previous cross-linguistic comparison of both of the involved languages in language contact in order to draw conclusions on the contact-induced language change in delimitation to language-internal development. While German is one of the best investigated languages with respect to its prosodic system, research on Turkish intonational phonology is not as progressed. To this effect, the analysis of bilingual Turkish, as elicited for the present dissertation, is preceded by an experimental study on monolingual Turkish. In this regard an additional experiment with 11 monolingual university students of non-linguistic subjects was conducted at the Ege University in Izmir in 2013. On these grounds the present dissertation additionally contributes new insights with respect to Turkish intonational phonology and typology. The results of the contrastive analysis of German and Turkish bring to light that the prosodic systems of both languages differ with respect to the use of prosodic cues in the marking of information structure (IS) and sentence type. Whereas German distinguishes in the prosodic marking between explicit categories for focus and givenness, Turkish uses only one prosodic cue to mark IS. Furthermore it is shown that Turkish in contrast to German does not use a prosodic correlate to mark yes/no questions, but a morphological question marker. To elicit Turkish yes/no questions in a bilingual context which differ with respect to their information structure in a further step the methodology of Xu (1999) to elicit in-situ focus on different constituents was adapted in the experimental study. A data set of 400 Turkish yes/no questions of 20 bilingual Turkish speakers was compiled at the Zentrum f{\"u}r Allgemeine Sprachwissenschaft (ZAS) in Berlin and at the University of Potsdam in 2013. The prosodic structure of the yes/no questions was phonologically and phonetically analyzed with respect to changes in the f0 contour according to IS modifications and the use of prosodic cues to indicate sentence type. The results of the analyses contribute surprising observations to the research of bilingual prosody. Studies on bilingual language change and language acquisition have repeatedly shown that the use of prosodic features that are considered as marked by means of lower and implicational use across and within a language cause difficulties in language contact and second language acquisition. Especially, they are not expected to pass from one language to another through language contact. However, this structurally determined expectation on language development is refuted by the results of the present study. Functionally related prosody, such as the cues to indicate IS, are transferred from German L2 to the Turkish L1 of German-Turkish bilingual speakers. This astonishing observation provides the base for an approach to language change centered on functional motivation. Based on Matras' (2007, 2010) assumption of functionality in language change, Paradis' (1993, 2004, 2008) approach of Language Activation and the Subsystem Theory and the Theory of Language as a Dynamic System (Heredina \& Jessner 2002), it will be shown that prosodic features which are absent in one of the languages of bilingual speech communities are transferred from the respective language to the other when they contribute to the contextualization of a pragmatic concept which is not expressed by other linguistic means in the target language. To this effect language interaction is based on language activation and inhibition mechanisms dealing with differences in the implicit pragmatic knowledge between bilinguals and monolinguals. The motivator for this process of language change is the contextualization of the message itself and not the structure of the respective feature on the surface. It is shown that structural consideration may influence language change but that bilingual language change does not depend on structural restrictions nor does the structure cause a change. The conclusions drawn on the basis of empirical facts can especially contribute to a better understanding of the processes of bilingual language development as it combines methodologies and theoretical aspects of different linguistic subfields.},

  abstract  = {This doctoral thesis seeks to elaborate how Wittgenstein's very sparse writings on ethics and ethical thought, together with his later work on the more general problem of normativity and his approach to philosophical problems as a whole, can be applied to contemporary meta-ethical debates about the nature of moral thought and language and the sources of moral obligation. I begin with a discussion of Wittgenstein's early "Lecture on Ethics", distinguishing the thesis of a strict fact/value dichotomy that Wittgenstein defends there from the related thesis that all ethical discourse is essentially and intentionally nonsensical, an attempt to go beyond the limits of sense. The first chapter discusses and defends Wittgenstein's argument that moral valuation always goes beyond any ascertaining of fact; the second chapter seeks to draw out the valuable insights from Wittgenstein's (early) insistence that value discourse is nonsensical while also arguing that this thesis is ultimately untenable and also incompatible with later Wittgensteinian understanding of language. On the basis of this discussion I then take up the writings of the American philosopher Cora Diamond, who has worked out an ethical approach in a very closely Wittgensteinian spirit, and show how this approach shares many of the valuable insights of the moral expressivism and constructivism of contemporary authors such as Blackburn and Korsgaard while suggesting a way to avoid some of the problems and limitations of their approaches. Subsequently I turn to a criticism of the attempts by Lovibond and McDowell to enlist Wittgenstein in the support for a non-naturalist moral realism. A concluding chapter treats the ways that a broadly Wittgensteinian conception expands the subject of metaethics itself by questioning the primacy of discursive argument in moral thought and of moral propositions as the basic units of moral belief.},

However, the outward wind also plays an essential role in the saturation in higher SN rate case. Algebraic expressions for the back reaction of the magnetic field onto the turbulent transport coefficients are derived, which allow a complete description of the nonlinear dynamo.

  abstract  = {Eine Krisensituation ist eine Umbruchssituation. Sie kann als Chance, als Herausforderung sowie im Sinne einer SCHUMPETER'SCHEN „sch{\"o}pferischen Zerst{\"o}rung" als Ausgangspunkt von bedeutsamen Ver{\"a}nderungen und neuen Entwicklungsm{\"o}glichkeiten begriffen werden. Die Krisensituation der 1970er und 1980er Jahre bildet dahingehend durch ihre Einzigartigkeit einen herausragenden wirtschaftshistorischen Untersuchungsgegenstand. F{\"u}r die westeurop{\"a}ischen Staaten waren es nicht nur Jahre einer, nach der außergew{\"o}hnlich langen Boomzeit der „Wirtschaftswunderjahre", problematischen sozialen und wirtschaftliche Situation. Es war auch eine Zeit eines bedeutungsvollen und beschleunigten Wandels. Die Gleichzeitigkeit vieler Ver{\"a}nderungen, das zeitliche Zusammentreffen von konjunkturellen und strukturellen Problemlagen sowie die {\"a}ußerst kritische Situation an den westeurop{\"a}ischen Arbeitsm{\"a}rkten bildete eine multiple Krisensituation. Deren Auswirkungen waren weitreichender, als es von den Zeitgenossen erahnt werden konnte. Es gab nicht nur {\"A}nderungen im (wirtschafts-)politischen Makrogef{\"u}ge vieler Volkswirtschaften, auch bedeutende Einfl{\"u}sse waren auf der Mikroebene feststellbar. Marktorientierte Unternehmen mussten sich auf die neue Situation einstellen und im Rahmen einer Neupositionierung von Betriebsstrategien, organisatorischen Umgestaltungen und einer st{\"a}rkeren Ressourcenorientierung betriebswirtschaftlich handeln. Das schien letztlich zu einer st{\"a}rkeren Beachtung und Entwicklung der in den Unternehmen vorhandenen humanen und sozialen Ressourcen zu f{\"u}hren. Diese Arbeit stellt die Hypothese auf, dass umfassende organisatorische Ver{\"a}nderungen und strategische Neupositionierungen, insbesondere die effektivere Nutzung sowie der intensive Auf- und Ausbau betriebsinterner Personalressourcen Unternehmen maßgeblich halfen, die Krisensituation der 1970er und 1980er Jahre besser und nachhaltiger {\"u}berwinden zu k{\"o}nnen. Anders als die bisherige wirtschaftshistorische Forschungsliteratur nimmt diese Dissertation nicht die makro{\"o}konomisch Perspektive in den Fokus, sondern untersucht die Hypothese anhand mehrerer Unternehmensfallstudien. Ausgew{\"a}hlt sind drei Großunternehmen der westeurop{\"a}ischen Elektroindustrie. Diese Arbeit liefert mit dieser Untersuchung einen weiteren Baustein zur wirtschaftshistorischen Ann{\"a}herung an die 1970er und 1980er Jahre und leistet ebenso einen Beitrag zur Fortschreibung der Firmengeschichte der drei Unternehmen. Die Elektrobranche fand bisher wirtschaftshistorisch nur wenig Beachtung, dennoch ist sie ein gutes Beispiel f{\"u}r die umfassende Ver{\"a}nderungssituation jener Jahre. Entsprechende Sekund{\"a}rquellen sind f{\"u}r diesen Zeitraum f{\"u}r die drei Unternehmen kaum vorhanden. Aus diesem Grund bildet eine Vielzahl von Archivalien das Fundament dieser Arbeit. Sie werden als Prim{\"a}rquellen aus den jeweiligen Unternehmensarchiven als Basis der Fallanalyse herangezogen. Mit Hilfe zahlreicher Dokumente des betrieblichen „Alltagsgesch{\"a}fts", wie beispielsweise Daten des betrieblichen Personal- und Rechnungswesens, Protokolle von Sitzungen der Arbeitsnehmervertreter, des Aufsichtsrats oder des Vorstands sowie interne Strategiepapiere und Statistiken, wird nicht nur der anfangs aufgestellten Hypothese nachgegangen, sondern auch mehrerer sich aus ihr ergebende Fragenkomplexe. Im Rahmen derer wird untersucht, wie die Unternehmen - die Besch{\"a}ftigten, die Leitungsebenen und die Aufsichtsr{\"a}te - auf die Krisensituation reagierten, ob sie ggf. ihrerseits Einfluss darauf zu nehmen versuchten und welche betriebswirtschaftlichen Schl{\"u}sse daraus gezogen wurden. Es wird hinterfragt, ob eine st{\"a}rkere Ressourcenorientierung wirklich eine neue Strategieperspektive bot und es diesbez{\"u}glich zu einer st{\"a}rkeren Beachtung humaner und sozialer Ressourcen im Unternehmen kam. Diese Arbeit untersucht, ob gezielt zur Krisen{\"u}berwindung in diese Ressourcen investiert wurde und diese Investitionen halfen, die Krisensituation erfolgreich zu {\"u}berstehen und nachhaltig den Unternehmenserfolg zu sichern.},

  abstract  = {The Milky Way is only one out of billions of galaxies in the universe. However, it is a special galaxy because it allows to explore the main mechanisms involved in its evolution and formation history by unpicking the system star-by-star. Especially, the chemical fingerprints of its stars provide clues and evidence of past events in the Galaxy's lifetime. These information help not only to decipher the current structure and building blocks of the Milky Way, but to learn more about the general formation process of galaxies. In the past decade a multitude of stellar spectroscopic Galactic surveys have scanned millions of stars far beyond the rim of the solar neighbourhood. The obtained spectroscopic information provide unprecedented insights to the chemo-dynamics of the Milky Way. In addition analytic models and numerical simulations of the Milky Way provide necessary descriptions and predictions suited for comparison with observations in order to decode the physical properties that underlie the complex system of the Galaxy. In the thesis various approaches are taken to connect modern theoretical modelling of galaxy formation and evolution with observations from Galactic stellar surveys. With its focus on the chemo-kinematics of the Galactic disk this work aims to determine new observational constraints on the formation of the Milky Way providing also proper comparisons with two different models. These are the population synthesis model TRILEGAL based on analytical distribution functions, which aims to simulate the number and distribution of stars in the Milky Way and its different components, and a hybrid model (MCM) that combines an N-body simulation of a Milky Way like galaxy in the cosmological framework with a semi-analytic chemical evolution model for the Milky Way. The major observational data sets in use come from two surveys, namely the "Radial Velocity Experiment" (RAVE) and the "Sloan Extension for Galactic Understanding and Exploration" (SEGUE). In the first approach the chemo-kinematic properties of the thin and thick disk of the Galaxy as traced by a selection of about 20000 SEGUE G-dwarf stars are directly compared to the predictions by the MCM model. As a necessary condition for this, SEGUE's selection function and its survey volume are evaluated in detail to correct the spectroscopic observations for their survey specific selection biases. Also, based on a Bayesian method spectro-photometric distances with uncertainties below 15\% are computed for the selection of SEGUE G-dwarfs that are studied up to a distance of 3 kpc from the Sun. For the second approach two synthetic versions of the SEGUE survey are generated based on the above models. The obtained synthetic stellar catalogues are then used to create mock samples best resembling the compiled sample of observed SEGUE G-dwarfs. Generally, mock samples are not only ideal to compare predictions from various models. They also allow validation of the models' quality and improvement as with this work could be especially achieved for TRILEGAL. While TRILEGAL reproduces the statistical properties of the thin and thick disk as seen in the observations, the MCM model has shown to be more suitable in reproducing many chemo-kinematic correlations as revealed by the SEGUE stars. However, evidence has been found that the MCM model may be missing a stellar component with the properties of the thick disk that the observations clearly show. While the SEGUE stars do indicate a thin-thick dichotomy of the stellar Galactic disk in agreement with other spectroscopic stellar studies, no sign for a distinct metal-poor disk is seen in the MCM model. Usually stellar spectroscopic surveys are limited to a certain volume around the Sun covering different regions of the Galaxy's disk. This often prevents to obtain a global view on the chemo-dynamics of the Galactic disk. Hence, a suitable combination of stellar samples from independent surveys is not only useful for the verification of results but it also helps to complete the picture of the Milky Way. Therefore, the thesis closes with a comparison of the SEGUE G-dwarfs and a sample of RAVE giants. The comparison reveals that the chemo-kinematic relations agree in disk regions where the samples of both surveys show a similar number of stars. For those parts of the survey volumes where one of the surveys lacks statistics they beautifully complement each other. This demonstrates that the comparison of theoretical models on the one side, and the combined observational data gathered by multiple surveys on the other side, are key ingredients to understand and disentangle the structure and formation history of the Milky Way.},

  abstract  = {Die vorliegende explorative empirische Untersuchung muslimischer Frauengruppen leistet einen Beitrag zur Erforschung des religi{\"o}sen Wandels im religi{\"o}sen Feld in Deutschland. Zum einen werden damit erstmals qualitative Daten zu religi{\"o}sen Gruppen muslimischer Frauen erhoben. Zum anderen liefern die analysierten Anl{\"a}sse der Gruppengr{\"u}ndung und die Gruppenziele Einblicke in die relevanten Themen des religi{\"o}s-muslimischen Engagements im Zeitverlauf. Gem{\"a}ß der explorativen Konzeption interessiert sich diese Studie insbesondere f{\"u}r die Vielfalt muslimischer Frauengruppen in Deutschland. Es wurde gefragt, welche Selbstbeschreibungen als muslimische Frauengruppen sich derzeit erkennen lassen? Dazu wurden thematische Leitfadeninterviews mit Ansprechpartnerinnen muslimischer Frauengruppen im religi{\"o}sen Feld (2006-2011) durchgef{\"u}hrt. Die Gr{\"u}ndungen der zw{\"o}lf untersuchten muslimischen Frauengruppen lagen im Zeitraum von 1978 bis 2009. Dies umfasst im Hinblick auf das muslimisch-religi{\"o}se Engagement Phasen mit unterschiedlichen Schwerpunkten, die von der Verfestigung der religi{\"o}sen Strukturen {\"u}ber den Kampf um rechtliche Gleichstellung als religi{\"o}se Minderheit bis zu einer Auseinandersetzung mit der staatlichen Islampolitik reichen. Die {\"a}ltesten der untersuchten Gruppen reflektieren in ihrem historischen Verlauf den Aufbau der religi{\"o}sen Strukturen, indem sie zun{\"a}chst R{\"a}ume f{\"u}r sich in den Gemeinden schufen. Diese f{\"u}llten sie in Form von religi{\"o}sen Bildungsprozessen und zwar indem sie einander an ihren Kenntnissen teilhaben ließen und gemeinsam die religi{\"o}se Quelle erschlossen. Andere Gruppen schlossen sich zusammen, um von den Kenntnissen religi{\"o}ser Expertinnen zu profitieren, wieder andere etablierten Angebote, die {\"u}ber den eigenen Gruppenzusammenhang hinausreichten. Mit dieser Ausrichtung der Weltgestaltung ging auch die Gr{\"u}ndung einer Organisation, d.h. ein Wandel der Sozialform einher. Die Ergebnisse konstatieren eine Kontingenz hinsichtlich der Selbstzuordnung muslimische Frauengruppe. Es handelt sich um historisch spezifische Selbstzuschreibungen, die Ausdruck eines religi{\"o}sen Wandels im muslimisch-religi{\"o}sen Feld initiiert von muslimischen Frauen sind. Zentrales Ergebnis ist hier, dass die Gruppen zwar hinsichtlich ihrer Formen heterogen sind, allerdings eine Verbindungslinie in ihren Kernideen als Frauengruppen- und Organisationen besteht. Es zeigt sich durch alle Phasen des muslimisch-religi{\"o}sen Engagements im religi{\"o}sen Feld ein hohes Interesse an religi{\"o}sen Bildungsthemen seitens muslimischer Frauen. Diese sind verbunden mit der Auseinandersetzung mit dem religi{\"o}sen Geschlechterverh{\"a}ltnis. Die Aufmerksamkeit, die das religi{\"o}se Geschlechterverh{\"a}ltnis im Kontext des Institutionalisierungs- und Partizipationsprozess des Islam im politischen Feld derzeit besitzt, kann einerseits als spezifisch gelten. Andererseits zeigen historische Kontextualisierungen mit der religi{\"o}sen Frauenbewegung im 19. Jahrhundert, dass auch hier {\"u}ber religi{\"o}se Geschlechterbilder Partizipationsfragen verhandelt wurden. Die Ergebnisse dieser Studie belegen die Relevanz von religi{\"o}sen Gruppen innerhalb religi{\"o}ser Wandlungsprozesse. Weiterhin liefern sie neue Erkenntnisse hinsichtlich des Verh{\"a}ltnisses von religi{\"o}ser Individualisierung und Gruppenbindung: Muslimische Frauen vergemeinschaften sich aus religi{\"o}sen Bildungszwecken innerhalb von religi{\"o}sen Gruppen und behandeln dabei Themen ihre weibliche religi{\"o}se Identit{\"a}t und die religi{\"o}se Lebensf{\"u}hrung als Frau betreffend und dies st{\"a}rkt ihre individuelle religi{\"o}se Bindung.},

  abstract  = {In the current paradigm of cosmology, the formation of large-scale structures is mainly driven by non-radiating dark matter, making up the dominant part of the matter budget of the Universe. Cosmological observations however, rely on the detection of luminous galaxies, which are biased tracers of the underlying dark matter. In this thesis I present cosmological reconstructions of both, the dark matter density field that forms the cosmic web, and cosmic velocities, for which both aspects of my work are delved into, the theoretical formalism and the results of its applications to cosmological simulations and also to a galaxy redshift survey.The foundation of our method is relying on a statistical approach, in which a given galaxy catalogue is interpreted as a biased realization of the underlying dark matter density field. The inference is computationally performed on a mesh grid by sampling from a probability density function, which describes the joint posterior distribution of matter density and the three dimensional velocity field. The statistical background of our method is described in Chapter "Implementation of argo", where the introduction in sampling methods is given, paying special attention to Markov Chain Monte-Carlo techniques. In Chapter "Phase-Space Reconstructions with N-body Simulations", I introduce and implement a novel biasing scheme to relate the galaxy number density to the underlying dark matter, which I decompose into a deterministic part, described by a non-linear and scale-dependent analytic expression, and a stochastic part, by presenting a negative binomial (NB) likelihood function that models deviations from Poissonity. Both bias components had already been studied theoretically, but were so far never tested in a reconstruction algorithm. I test these new contributions againstN-body simulations to quantify improvements and show that, compared to state-of-the-art methods, the stochastic bias is inevitable at wave numbers of k≥0.15h Mpc^-1 in the power spectrum in order to obtain unbiased results from the reconstructions. In the second part of Chapter "Phase-Space Reconstructions with N-body Simulations" I describe and validate our approach to infer the three dimensional cosmic velocity field jointly with the dark matter density. I use linear perturbation theory for the large-scale bulk flows and a dispersion term to model virialized galaxy motions, showing that our method is accurately recovering the real-space positions of the redshift-space distorted galaxies. I analyze the results with the isotropic and also the two-dimensional power spectrum.Finally, in Chapter "Phase-space Reconstructions with Galaxy Redshift Surveys", I show how I combine all findings and results and apply the method to the CMASS (for Constant (stellar) Mass) galaxy catalogue of the Baryon Oscillation Spectroscopic Survey (BOSS). I describe how our method is accounting for the observational selection effects inside our reconstruction algorithm. Also, I demonstrate that the renormalization of the prior distribution function is mandatory to account for higher order contributions in the structure formation model, and finally a redshift-dependent bias factor is theoretically motivated and implemented into our method. The various refinements yield unbiased results of the dark matter until scales of k≤0.2 h Mpc^-1in the power spectrum and isotropize the galaxy catalogue down to distances of r∼20h^-1 Mpc in the correlation function. We further test the results of our cosmic velocity field reconstruction by comparing them to a synthetic mock galaxy catalogue, finding a strong correlation between the mock and the reconstructed velocities. The applications of both, the density field without redshift-space distortions, and the velocity reconstructions, are very broad and can be used for improved analyses of the baryonic acoustic oscillations, environmental studies of the cosmic web, the kinematic Sunyaev-Zel'dovic or integrated Sachs-Wolfe effect.},

In contrast to their predecessors, the new donors have committed themselves to be more pragmatic, innovative and flexible in their development cooperation measures. However, they are also criticized for weakening the function of local civil society and have the reputation of being an intransparent and often controversial alternative to public services. With additional financial resources and their new approach to development, the new donors have been described in the literature as playing a controversial role in transforming development cooperation. This dissertation compares the effectiveness of initiatives by new and conventional donors with regard to the provision of public goods and services to the poor in the water and sanitation sector in India. India is an emerging country but it is experiencing high poverty rates and poor water supply in predominantly rural areas. It lends itself for analyzing this research theme as it is currently being confronted by a large number of actors and approaches that aim to find solutions for these challenges . In the theoretical framework of this dissertation, four governance configurations are derived from the interaction of varying actor types with regard to hierarchical and non-hierarchical steering of their interactions. These four governance configurations differ in decision-making responsibilities, accountability and delegation of tasks or direction of information flow. The assumption on actor relationships and steering is supplemented by possible alternative explanations in the empirical investigation, such as resource availability, the inheritance of structures and institutions from previous projects in a project context, gaining acceptance through beneficiaries (local legitimacy) as a door opener, and asymmetries of power in the project context. Case study evidence from seven projects reveals that the actors' relationship is important for successful project delivery. Additionally, the results show that there is a systematic difference between conventional and new donors. Projects led by conventional donors were consistently more successful, due to an actor relationship that placed the responsibility in the hands of the recipient actors and benefited from the trust and reputation of a long-term cooperation. The trust and reputation of conventional donors always went along with a back-up from federal level and trickled down as reputation also at local level implementation. Furthermore, charismatic leaders, as well as the acquired structures and institutions of predecessor projects, also proved to be a positive influencing factor for successful project implementation. Despite the mixed results of the seven case studies, central recommendations for action can be derived for the various actors involved in development cooperation. For example, new donors could fulfill a supplementary function with conventional donors by developing innovative project approaches through pilot studies and then implementing them as a supplement to the projects of conventional donors on the ground. In return, conventional donors would have to make room the new donors by integrating their approaches into already programs in order to promote donor harmonization. It is also important to identify and occupy niches for activities and to promote harmonization among donors on state and federal sides. The empirical results demonstrate the need for a harmonization strategy of different donor types in order to prevent duplication, over-experimentation and the failure of development programs. A transformation to successful and sustainable development cooperation can only be achieved through more coordination processes and national self-responsibility.},
