Moreover, language processing depends on top-down information, such as the predictability of a word from a previous context. Yet, however, the exact role of top-down predictions in visual word recognition is poorly understood: They may rapidly affect lexical processes, or alternatively, influence only late post-lexical stages. To add evidence about the nature of top-down processes and their relation to bottom-up information in the timeline of word recognition, we examined influences of frequency and predictability on event-related potentials (ERPs) in several sentence reading studies. The results were related to eye movements from natural reading as well as to models of word recognition. As a first and major finding, interactions of frequency and predictability on ERP amplitudes consistently revealed top-down influences on lexical levels of word processing (Chapters 2 and 4). Second, frequency and predictability mediated relations between N400 amplitudes and fixation durations, pointing to their sensitivity to a common stage of word recognition; further, larger N400 amplitudes entailed longer fixation durations on the next word, a result providing evidence for ongoing processing beyond a fixation (Chapter 3). Third, influences of presentation rate on ERP frequency and predictability effects demonstrated that the time available for word processing critically co-determines the course of bottom-up and top-down influences (Chapter 4). Fourth, at a near-normal reading speed, an early predictability effect suggested the rapid comparison of top-down hypotheses with the actual visual input (Chapter 5). The present results are compatible with interactive models of word recognition assuming that early lexical processes depend on the concerted impact of bottom-up and top-down information. We offered a framework that reconciles the findings on a timeline of word recognition taking into account influences of frequency, predictability, and presentation rate (Chapter 4).}, language = {en} } @book{OPUS4-4066, title = {Baset - Bubastis - Tell Basta}, series = {Arcus: Berichte aus Arch{\"a}ologie, Baugeschichte und Nachbargebieten}, journal = {Arcus: Berichte aus Arch{\"a}ologie, Baugeschichte und Nachbargebieten}, number = {8}, editor = {Tietze, Christian and Lange, Eva}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-937786-31-5}, issn = {0947-1081}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-42682}, publisher = {Universit{\"a}t Potsdam}, pages = {201}, year = {2005}, abstract = {Inhalt: Habachi, Labib: Tell Basta Chapter 1: Introductory: Bubatis and its monuments Chapter II: The temple of Pepi I [I]: Description Chapter III: The temple of Pepi [III]: Finds and importance Chapter IV: General notes on the great temple [I]: Mihos temple and entrance hall Chapter V: General notes on the great temple [II]: Festival hall and hypostyle hall Chapter VI: General notes on the great temple [III]: The temple of Nektanebos (Nekht-har-hebi) Chapter VII: Work outside the temples Chapter VIII: Blocks transferred to Bubastis Chapter IX: Blocks removed from Bubastis Farid, Shafik: Preliminary report on the excavations of the antiquities department at Tell Basta}, language = {en} } @book{Lkhagvadorj2010, author = {Lkhagvadorj, Ariunaa}, title = {Fiscal federalism and decentralization in Mongolia}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-053-3}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-41768}, publisher = {Universit{\"a}t Potsdam}, pages = {178}, year = {2010}, abstract = {Fiscal federalism has been an important topic among public finance theorists in the last four decades. There is a series of arguments that decentralization of governments enhances growth by improving allocation efficiency. However, the empirical studies have shown mixed results for industrialized and developing countries and some of them have demonstrated that there might be a threshold level of economic development below which decentralization is not effective. Developing and transition countries have developed a variety of forms of fiscal decentralization as a possible strategy to achieve effective and efficient governmental structures. A generalized principle of decentralization due to the country specific circumstances does not exist. Therefore, decentralization has taken place in different forms in various countries at different times, and even exactly the same extent of decentralization may have had different impacts under different conditions. The purpose of this study is to investigate the current state of the fiscal decentralization in Mongolia and to develop policy recommendations for the efficient and effective intergovernmental fiscal relations system for Mongolia. Within this perspective the analysis concentrates on the scope and structure of the public sector, the expenditure and revenue assignment as well as on the design of the intergovernmental transfer and sub-national borrowing. The study is based on data for twenty-one provinces and the capital city of Mongolia for the period from 2000 to 2009. As a former socialist country Mongolia has had a highly centralized governmental sector. The result of the analysis below revealed that the Mongolia has introduced a number of decentralization measures, which followed a top down approach and were slowly implemented without any integrated decentralization strategy in the last decade. As a result Mongolia became de-concentrated state with fiscal centralization. The revenue assignment is lacking a very important element, for instance significant revenue autonomy given to sub-national governments, which is vital for the efficient service delivery at the local level. According to the current assignments of the expenditure and revenue responsibilities most of the provinces are unable to provide a certain national standard of public goods supply. Hence, intergovernmental transfers from the central jurisdiction to the sub-national jurisdictions play an important role for the equalization of the vertical and horizontal imbalances in Mongolia. The critical problem associated with intergovernmental transfers is that there is not a stable, predictable and transparent system of transfer allocation. The amount of transfers to sub-national governments is determined largely by political decisions on ad hoc basis and disregards local differences in needs and fiscal capacity. Thus a fiscal equalization system based on the fiscal needs of the provinces should be implemented. The equalization transfers will at least partly offset the regional disparities in revenues and enable the sub-national governments to provide a national minimum standard of local public goods.}, language = {en} } @book{KunzeStrohe2010, author = {Kunze, Karl-Kuno and Strohe, Hans Gerhard}, title = {Time-varying persistence in the German stock market}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-42046}, publisher = {Universit{\"a}t Potsdam}, year = {2010}, abstract = {This paper studies the persistence of daily returns of 21 German stocks from 1960 to 2008.

Other types of metadata that are important for effective integration and meaningful querying of such data sets are missing. In particular, relationships among attributes, such as foreign keys, are crucial metadata for understanding the structure of an unknown database. The discovery of such relationships is difficult, because in principle for each pair of attributes in the database each pair of data values must be compared. A precondition for a foreign key is an inclusion dependency (IND) between the key and the foreign key attributes. We present with Spider an algorithm that efficiently finds all INDs in a given relational database. It leverages the sorting facilities of DBMS but performs the actual comparisons outside of the database to save computation. Spider analyzes very large databases up to an order of magnitude faster than previous approaches. We also evaluate in detail the effectiveness of several heuristics to reduce the number of necessary comparisons. Furthermore, we generalize Spider to find composite INDs covering multiple attributes, and partial INDs, which are true INDs for all but a certain number of values.

In particular, these techniques hold great promise for the development of "systems infrastructure" software, e.g., application servers, middleware, virtual machines, compilers, operating systems, and other software that provides general services for higher-level applications. The developers of infrastructure software are faced with increasing demands from application programmers needing higher-level support for application development. Meeting these demands requires careful use of software modularization techniques, since infrastructural concerns are notoriously hard to modularize. Aspects, components, and patterns provide very different means to deal with infrastructure software, but despite their differences, they have much in common. For instance, component models try to free the developer from the need to deal directly with services like security or transactions. These are primary examples of crosscutting concerns, and modularizing such concerns are the main target of aspect-oriented languages. Similarly, design patterns like Visitor and Interceptor facilitate the clean modularization of otherwise tangled concerns. Building on the ACP4IS meetings at AOSD 2002-2009, this workshop aims to provide a highly interactive forum for researchers and developers to discuss the application of and relationships between aspects, components, and patterns within modern infrastructure software.

Policies to combat these problems are usually connected to socio-economic regeneration in England and economic and employment promotion (Wirtschafts- und Besch{\"a}ftigungsf{\"o}rderung) in Germany. The main result of this project is a description of those factors which support the emergence of local socio-economic initiatives aimed at job creation. Eight social and formal economy initiatives have been examined and the ways in which their emergence has been influenced by institutional factors has been analysed. The role of local actors and forms of governance as well as wider regional and national policy frameworks has been taken into account. Socio-economic initiatives have been defined as non-routine local projects or schemes with the objective of direct job creation. Such initiatives often focus on specific local assets for the formal or the social economy. Socio-economic initiatives are grounded on ideas of local economic development, and the creation of local jobs for local people. The adopted understanding of governance focuses on the processes of decision taking. Thus, this understanding of governance is broadly construed to include the ways in which actors in addition to traditional government manage urban development. The applied understanding of governance lays a focus on 'strategic' forms of decision taking about both long term objectives and short term action linked to socio-economic regeneration. Four old industrial towns in North England and East Germany have been selected for case studies due to their particular socio-economic background. These towns, with between 10.000 and 70.000 inhabitants, are located outside of the main agglomerations and bear central functions for their hinterland. The approach has been comparative, with a focus on examining common themes rather than gaining in-depth knowledge of a single case.

In this paper we consider the problem of offering recommendations to the user during the act of modeling. Our key contribution is a concept for defining and identifying so-called action patterns - chunks of actions often appearing together in business processes. In particular, we specify action patterns and demonstrate how they can be identified from existing process model repositories using association rule mining techniques. Action patterns can then be used to suggest additional actions for a process model. Our approach is challenged by applying it to the collection of process models from the SAP Reference Model.}, language = {en} } @book{PolyvyanyyKuropka2007, author = {Polyvyanyy, Artem and Kuropka, Dominik}, title = {A quantitative evaluation of the enhanced topic-based vector space model}, isbn = {978-3-939469-95-7}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-33816}, publisher = {Universit{\"a}t Potsdam}, year = {2007}, abstract = {This contribution presents a quantitative evaluation procedure for Information Retrieval models and the results of this procedure applied on the enhanced Topic-based Vector Space Model (eTVSM). 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.}, language = {en} } @book{BreestBoucheGrundetal.2006, author = {Breest, Martin and Bouch{\´e}, Paul and Grund, Martin and Haubrock, S{\"o}ren and H{\"u}ttenrauch, Stefan and Kylau, Uwe and Ploskonos, Anna and Queck, Tobias and Schreiter, Torben}, title = {Fundamentals of Service-Oriented Engineering}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-939469-35-3}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-33801}, publisher = {Universit{\"a}t Potsdam}, pages = {Getr.
