TY - BOOK ED - Bergström, Tomas ED - Franzke, Jochen ED - Kuhlmann, Sabine ED - Wayenberg, Ellen T1 - The Future of Local Self-Government BT - European Trends in Autonomy, Innovations and Central-Local Relations T3 - Palgrave Studies in Sub-National Governance N2 - This book presents new research results on the challenges of local politics in different European countries, including Germany, the Netherlands, the Nordic countries and Switzerland, together with theoretical considerations on the further development and strengthening of local self-government. It focuses on analyses of the most recent developments in local democracy and administration. “Most ‘local government’ books are written by believers. This book is different for its realistic visions of futures of local government. It shows how autonomy, digitalization, marketization, and amalgamation could be functional or dysfunctional, and also how this is affected by links to politics, and impacted by intergovernmental relations. This is a must read for all believers in local government.” —Geert Bouckaert, KU Leuven Public Governance Institute, Belguim “The twenty chapters of this book provide a timely and thought-provoking addition to our understanding of local self-governance in eight countries in Northern and Central Europe. This book was completed shortly before the Corona-crisis crashed in. But the lessons to be learned from this volume will doubtlessly prove important in fully exploiting local government’s potential in facing the challenges of the difficult times ahead.” —Bas Denters, Professor of Public Administration, University of Twente, Netherlands “Very inspiring book that covers the most important aspects of local self-government within a comparative framework. As we might have expected, there is no general trend, no single best model but a variety of functionally equivalent settings and patterns. The book gives insight into the diversity and richness of local government, its very essence, actual challenges and transformations, and puts subnational policy making in a multi-level perspective of governance.” —Andreas Ladner, Professor for Political Institutions and Public Administration at the IDHEAP, University of Lausanne, Switzerland “Covering eight countries, this ambitious volume compares developments in local governments across Europe. Local governments are on the front-line when it comes to responding to wicked issues like climate change and migration, yet face major challenges in terms of financial and human resources. Using rich empirical evidence, the volume presents a nuanced analysis of trends. No one direction emerges for Europe’s local governments, but a rich seam of innovation is revealed covering political participation and public administration alike. Local governments have the potential to engage citizens in meaningful ways and deliver effective and responsive services, but this requires clear local leadership and support rather direction from the centre.” KW - Political science KW - Public administration KW - Governance and Government Y1 - 2021 SN - 978-3-030-56059-1 U6 - https://doi.org/10.1007/978-3-030-56059-1 PB - Springer CY - Cham ER - TY - BOOK T1 - Tackling investment challenges in power generation BT - In IEA countries KW - Energieerzeugung KW - Investitionspolitik KW - Nachhaltigkeit Y1 - 2007 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-bbdig-70 SN - 978-92-64-03007-7 PB - OECD/IEA CY - Paris ER - TY - BOOK A1 - Taneja, Preti T1 - Assimilation, exodus, eradication BT - Iraq’s minority communities since 2003 KW - Irak KW - Minderheit KW - Geschichte 2003-2006 Y1 - 2007 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-bbdig-87 SN - 1-904584-60-8 PB - Minority Rights Group International CY - London ER - TY - BOOK ED - Meinel, Christoph ED - Polze, Andreas ED - Oswald, Gerhard ED - Strotmann, Rolf ED - Seibold, Ulrich ED - Schulzki, Bernard T1 - HPI Future SOC Lab BT - Proceedings 2012 N2 - The “HPI Future SOC Lab” is a cooperation of the Hasso-Plattner-Institut (HPI) and industrial partners.

N2 - Despite its many challenges and limitations the concept of in situ upgrading of informal settlements has become one of the most favoured approaches to the housing crisis in the ‘Global South’. Due to its inherent principles of incremental in situ development, prevention of relocations, protection of local livelihoods and democratic participation and cooperation, this approach is often perceived to be more sustainable than other housing approaches that often rely on quantitative housing delivery and top down planning methodologies. While this study does not question the benefits of the in situ upgrading approach, it seeks to identify problems of its practical implementation within a specific national and local context. The study discusses the origin and importance of this approach on the basis of a review of international housing policy development and analyses the broader political and social context of the incorporation of this approach into South African housing policy. It further uses insights from a recent case study in Cape Town to determine complications and conflicts that can arise when applying in situ upgrading of informal settlements in a complex local context. On that basis benefits and limitations of the in situ upgrading approach are specified and prerequisites for its successful implementation formulated. N2 - Trotz vieler Herausforderungen und Beschränkungen gilt das Konzept des in situ upgrading informeller Siedlungen als eine der wichtigsten Herangehensweisen an die Wohnraumkrise im „globalen Süden“. Aufgrund seiner immanenten Prinzipien einer schrittweisen Entwicklung an Ort und Stelle, der Vermeidung von Umsiedlungen, dem Erhalt lokaler Existenzgrundlagen sowie demokratischer Beteiligung und Kooperation, wird oftmals angenommen, dass diese Herangehensweise nachhaltiger ist, als eine quantitativ ausgerichtete Wohnraumversorgung und Top-Down-Planungsansätze. Während diese Studie die Vorteile des in situ upgrading nicht in Frage stellt, zielt sie darauf ab, Probleme der praktischen Umsetzung dieses Ansatzes in einem spezifischen nationalen und lokalen Kontext zu identifizieren. Die Studie diskutiert die Herkunft und die Bedeutung des in situ upgrading auf der Grundlage einer Rückschau auf die Entwicklung internationaler Wohnraumpolitik und analysiert den politischen und sozialen Kontext der Einbettung dieses Ansatzes in die südafrikanische Wohnraumpolitik. Darüber hinaus macht sie sich Einblicke einer kürzlich durchgeführten Fallstudie in Kapstadt zunutze, um Probleme und Konflikte zu erfassen, die bei der Umsetzung des in situ upgrading in einem komplexen lokalen Kontext entstehen können. Auf dieser Grundlage werden die Vorteile wie auch die Beschränkungen des in situ upgrading näher spezifiziert und zentrale Voraussetzungen für eine erfolgreiche Umsetzung des Konzeptes formuliert.

To test the influence of the covariate we transform the model in a regression model. Since censoring is allowed this approach leads to a goodness-of-fit problem for regression functions under censoring. So nonparametric estimation of regression functions under censoring is investigated, a limit theorem for a L2-distance is stated and a test procedure is formulated. Finally a Monte Carlo procedure is proposed.

On the screen we see pictorial elements that have to be manipulated to master a game, that is to win a competition, to solve a riddle or to adopt a skill. Therefore the characteristics of the representational function of computer games have to be contrasted phenomenologically with conventional games on the one hand and cinematic depictions on the other. It shows that computer games separate the player from the playing field, and translate bodily felt concrete actions into situational abstract cinematic depictions. These features add up to the situational abstract presentation of self-action experience. In this framework computer games reveal a potential as a new means of shared cognition that might unfold in the 21st century and change the beingin- the-world in a similar way as cinematic depiction did in the 20th century Y1 - 2010 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:517-opus-42770 ER - TY - BOOK A1 - Kunze, Karl-Kuno A1 - Strohe, Hans Gerhard T1 - Antipersistence in German stock returns N2 - Persistence of stock returns is an extensively studied and discussed theme in the analysis of financial markets. Antipersistence is usually attributed to volatilities. However, not only volatilities but also stock returns can exhibit antipersistence. Antipersistent noise has a somewhat rougher appearance than Gaussian noise. Heuristically spoken, price movements are more likely followed by movements in the opposite direction than in the same direction. The pertaining integrated process exhibits a smaller range – prices seem to stay in the vicinity of the initial value. We apply a widely used test based upon the modified R/S-Method by Lo [1991] to daily returns of 21 German stocks from 1960 to 2008. Combining this test with the concept of moving windows by Carbone et al. [2004], we are able to determine periods of antipersistence for some of the series under examination. Our results suggest that antipersistence can be found for stocks and periods where extraordinary corporate actions such as mergers & acquisitions or financial distress are present. These effects should be properly accounted for when choosing and designing models for inference.

T1 - The Celtic Englishes IV : the interface between english and the celtic languages ; proceedings of the fourth International Colloquium on the "Celtic Englishes" held at the University of Potsdam in Golm (Germany) from 22 - 26 September 2004 N2 - What is "Celtic"and what is universal in the "Celtic Englishes"? This was the central concern of the fourth and final Colloquium of studies on language contact between English and the Celtic languages at the University of Potsdam in September 2004. The contributions to this volume discuss the "Celtic" peculiarities of Standard English in England and in Ireland (North and South). They also examine the perceived "Celticity" of personal names in the "Celtic" countries (Ireland, Wales, Cornwall, Brittany). Moreover, they put emphasis on specific grammatical features such as the expression of perfectivity, relativity, intensification and the typological shift of verbal word formation from syntheticity to analycity as well as the emergence of universal contact trends shared by Celtic, African and Indian Englishes. Thus, the choice of contributors and the scope of their articles makes Celtic Englishes IV an invaluable handbook for scholarly work in the field of the English - Celtic relations.

Since the eTVSM is an ontology-based model, its effectiveness heavily depends on the quality of the underlaying ontology. Therefore the model has been tested with different ontologies to evaluate the impact of those ontologies on the effectiveness of the eTVSM. On the highest level of abstraction, the following results have been observed during our evaluation: First, the theoretically deduced statement that the eTVSM has a similar effecitivity like the classic Vector Space Model if a trivial ontology (every term is a concept and it is independet of any other concepts) is used has been approved. Second, we were able to show that the effectiveness of the eTVSM raises if an ontology is used which is only able to resolve synonyms. We were able to derive such kind of ontology automatically from the WordNet ontology. Third, we observed that more powerful ontologies automatically derived from the WordNet, dramatically dropped the effectiveness of the eTVSM model even clearly below the effectiveness level of the Vector Space Model. Fourth, we were able to show that a manually created and optimized ontology is able to raise the effectiveness of the eTVSM to a level which is clearly above the best effectiveness levels we have found in the literature for the Latent Semantic Index model with compareable document sets.

To correct these misunderstandings, a deeper knowledge of the concepts, the historical backgrounds, and an overview of service-oriented architectures is demanded and given in this paper.

Services will provide an self-contained and standardised interface towards business and are considered as the future platform for business-to-business and business-toconsumer trades. Founded by the complexity of real world business scenarios a huge need for an easy, flexible and automated creation and enactment of service compositions is observed. This survey explores the relationship of service composition with workflow management—a technology/ concept already in use in many business environments. The similarities between the both and the key differences between them are elaborated. Furthermore methods for composition of services ranging from manual, semi- to full-automated composition are sketched. This survey concludes that current tools for service composition are in an immature state and that there is still much research to do before service composition can be used easily and conveniently in real world scenarios. However, since automated service composition is a key enabler for the full potential of Service-oriented Architectures, further research on this field is imperative. This survey closes with a formal sample scenario presented in appendix A to give the reader an impression on how full-automated service composition works.

To understand position and orientation of aggregated components of a CSG model, we need to realize its visible and occluded parts as a whole. Hence, transparency and enhanced outlines are key techniques to assist comprehension. We present a novel real-time rendering technique for visualizing design and spatial assembly of CSG models. As enabling technology we combine an image-space CSG rendering algorithm with blueprint rendering. Blueprint rendering applies depth peeling for extracting layers of ordered depth from polygonal models and then composes them in sorted order facilitating a clear insight of the models. We develop a solution for implementing depth peeling for CSG models considering their depth complexity. Capturing surface colors of each layer and later combining the results allows for generating order-independent transparency as one major rendering technique for CSG models. We further define visually important edges for CSG models and integrate an image-space edgeenhancement technique for detecting them in each layer. In this way, we extract visually important edges that are directly and not directly visible to outline a model’s layout. Combining edges with transparency rendering, finally, generates edge-enhanced depictions of image-based CSG models and allows us to realize their complex, spatial assembly.

Let Y be a matrix of manifest variables and H the matrix of the corresponding latent variables. And let H = BH+ε be a structural PLS model with a coefficient matrix B. Then this model can be made a dynamic one by substituting for B a matrix F = B + CL containing the lag operator L. Then the structural dynamic model H = FH+ε is formally estimated like an ordinary PLS model. In an exploratory way the model can be used for forecasting purposes. The procedure is being programmed in ISP.

The first paper on “Biased Questions” is an invited contribution by Nicholas Asher (CNRS, Laboratoire IRIT) & Brian Reese (University of Texas at Austin). Surveying English tag questions, negative polar questions, and what they term “focus” questions, they investigate the effects of prosody on discourse function and discourse structure and analyze the interaction between prosody and discourse in SDRT (Segmented Discourse Representation Theory). Stefan Hinterwimmer (A2) explores the interpretation of singular definites and universally quantified DPs in adverbially quantified English sentences. He suggests that the availability of a co-varying interpretation is more constrained in the case of universally quantified DPs than in the case of singular definites, because different from universally quantified DPs, co-varying definites are inherently focus-marked. The existence of striking similarities between topic/comment structure and bimanual coordination is pointed out and investigated by Manfred Krifka (A2). Showing how principles of bimanual coordination influence the expression of topic/comment structure beyond spoken language, he suggests that bimanual coordination might have been a preadaptation of the development of Information Structure in human communication. Among the different ways of expressing focus in Foodo, an underdescribed African Guang language of the Kwa family, the marked focus constructions are the central topic of the paper by Ines Fiedler (B1 & D2). Exploring the morphosyntactic facilities that Foodo has for focalization, she suggests that the two focus markers N and n have developed out of a homophone conjunction. Focus marking in another scarcely documented African tone language, the Gur language Konkomba, is treated by Anne Schwarz (B1 & D2). Comparing the two alleged focus markers lé and lá of the language, she argues that lé is better interpreted as a syntactic device rather than as a focus marker and shows that this analysis is corroborated by parallels in related languages. The reflexes of Information Structure in four different European languages (French, German, Greek and Hungarian) are compared and validated by Sam Hellmuth & Stavros Skopeteas (D2). The production data was collected with selected materials of the Questionnaire on Information Structure (QUIS) developed at the SFB. The results not only allow for an evaluation of the current elicitation paradigms, but also help to identify potentially fruitful venues of future research. Frank Kügler, Stavros Skopeteas (D2) & Elisabeth Verhoeven (University of Bremen) give an account of the encoding of Information Structure in Yucatec Maya, a Mayan tone language spoken on the Yucatecan peninsula in Mexico. The results of a production experiment lead them to the conclusion that focus is mainly expressed by syntax in this language. Stefanie Jannedy (D3) undertakes an instrumental investigation on the expressions and interpretation of focus in Vietnamese, a language of the Mon-Khmer family contrasting six lexical tones. The data strongly suggests that focus in Vietnamese is exclusively marked by prosody (intonational emphasis expressed via duration, f0 and amplitude) and that different focus conditions can reliably be recovered. This volume offers insights into current work conducted at the SFB 632, comprising empirical and theoretical aspects of Information Structure in a multitude of languages. Several of the papers mine field work data collected during the first phase of the SFB and explore the expression of Information Structure in tone and non-tone languages from various regions of the world.

We show that sentences containing the former type of Q-adverb evidence that Quantificational Variability Effects (Berman 1991) come about as an indirect effect of quantification over situations: in order for quantificational variability readings to arise, these sentences have to obey two newly observed constraints that clearly set them apart from sentences containing corresponding quantificational DPs, and that can plausibly be explained under the assumption that quantification over (the atomic parts of) complex situations is involved. Concerning sentences with the latter type of Q-adverb, on the other hand, such evidence is lacking: with respect to the constraints just mentioned, they behave like sentences that contain corresponding quantificational DPs. We take this as evidence that Q-adverbs like for the most part do not quantify over the atomic parts of sum eventualities in the cases under discussion (as claimed by Nakanishi and Romero (2004)), but rather over the atomic parts of the respective sum individuals.

The social contract defines the rules of resource use. An intergenerational social contract in an economy with a single exhaustible resource is examined within a framework of an overlapping generations model. It is assumed that new generations do not accept the old social contract, and access to resources will be renegotiated between any incumbent generation and their successors. It turns out that later generations will be in an unfortunate position regardless of their bargaining power.
