The debate devoted to budget issues, which gets more intense every autumn, testifies to increasing problems with correcting guidelines for distribution of expenditures. Even slight changes stand for depriving a specified group of transfers, what in democratic conditions produces strong protests. A similar negative attitude to changes became evident with regard to taxation. Recommendations presented in 1998 by the Polish government [see Ministry of Finance, 1998a, 1998b] introduce substantial modifications to the current tax system (withdrawal from tax exemptions and introduction of a tax-free minimum income) and thus met with a massive reluctance of major political fractions.

The socialistic systems were not able to fulfill the necessary functions in providing a certain degree of redistribution and social security, which are inevitable for social oriented market economies. Increasing income and wage differentiation is one of the most important prerequisites for a market oriented ability to pay tax system. But in the transformation period, numerous quasi-legal or even illegal property transactions have taken place, thus leading to wealth concentrations on the one hand while as consequence of the bankruptcy of socialism, enormous poverty problems have arisen on the other. For the political acceptance of the transformation process it is of utmost importance that an efficient and fair tax system is implemented and social security is organised by the state on a level which secures at least the physical minimum of subsistence or - if economically possible - even a social-cultural minimum. Whether the state should go further in providing compulsory social insurance systems has been a hotly debated topic for decades even in the welfare and social states of the Western type. Whereas the basic security systems have to be financed by general tax revenue, for a compulsory social insurance system - due to the insurance character - special earmarked social security contribution are held necessary. Both public goods and services as well as at least basic security have to be financed by total tax revenue. For the acceptance and fairness of the whole system the total redistributive effect of both sides of the budget - the tax system as well as the expenditure system - are decisive. In this paper we will concentrate on the revenue side, e.g. on the taxes as well as on the social security contributions. Adam Smith had already formulated some very simple tax norms which have been transformed in modern tax theory. The equivalence as well as the ability-topay principle are basic yardsticks for every tax system in a democratic oriented market system, not to forget tax fairness. In the historical development process equity-oriented measures have often produced an enormous complexity of the single taxes as well as of the whole tax system. Therefore, reconsidering the Smithian principles of simplicity and of minimum compliance costs for the tax payer would even press many Western European tax systems to undergo serious reform processes which often are delayed because of intense interest group influence. Hence, a modern tax system is a simple one which consists only of a few single taxes which are easy to administer. Such a system consists of two main taxes, the income and the value added tax. Consequently in all countries of transition both taxes have been implemented, while the implementation was fostered by the fact that both also constitute the typical components of the EU member states systems. Therefore such a harmonising tax reform is the most important prerequisite to become a membership candidate. Bulgaria also tried to follow this general pattern in reforming the income tax system starting in 1992 and replacing the old socialistic turnover tax and excise duty system by the value added tax (VAT) in 1994. Especially with regard to the income tax system the demand for simplicity has not been met yet. Complex rules to define the tax base as well as a steeply progressive tax schedule have led to behavioral adaptations which are even strengthened by the effects of a high social contribution burden which is predominantly laid on the employers. In the following some concise descriptions of the tax and social contribution system are given; the paper closes with a summary, in which the impacts of the system are evaluated and some political recommendations for further reforms are presented.}, language = {en} } @book{BakardjievaSowada1999, author = {Bakardjieva, Radostina and Sowada, Christoph}, title = {The employment crisis, pensions and poverty in Bulgaria 1990-1998 : trends - consequences - preventative measures}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-48899}, publisher = {Universit{\"a}t Potsdam}, year = {1999}, abstract = {After promising beginnings towards transformation, in 1991 the Bulgarian economy fell into deep crisis in the period from 1995 to 1997.

A range of issues have been raised which demand closer empirical investigation. For this purpose, the research group has developed questionnaire studies for Bulgaria and Poland. In Bulgaria, the National Statistical Institute (NSI) carried out the case studies between February and April 1998. The problems of the questionnaire set-up were identified in apre-test study, but unlike the Polish case, they led to only minor differentiation. Since financial limitations prevented a larger sample size, a sample size of 61 mid-sized and large Bulgarian enterprises was selected. Failure to respond was not a serious problem, unlike with the Polish questionnaire; this is because the NSI has maintained good links to the enterprise sector and management were prepared to give detailed answers, even on questions of their firms' financial status. However, as the Polish experience suggests, it has become obvious that the privatisation process is also associated with management's increasing reluctance to answer comparatively 'intimate' questions. Thus, future questionnaire studies must take a much higher rate of refusals into consideration. The pre-selection procedure in Bulgaria was determined by the project target, which sought to analyse the effects of the privatisation process on firm' s behaviour during the transition process, and hence only firms which had already existed before the changes were included. For small and medium-size enterprises (SME's), most of which were founded after the changes, partly due to the legal processes of spontaneous privatisation, some empirical, as weIl as analytical, studies were carried out. Thus, the research group limited the scope of investigation to enterprises with more than 250 employees. The underlying hypothesis is that employment problems are concentrated in larger firms, in particular amongst those still (partly) state owned. Because of the former ownership structures and relatively slower capacity for management change, the assumption is that state-owned enterprises (SOE's) which have only been recently privatised might still have traditional links to government even after privatisation. On the one hand, the SME's are obviously more prone to, and linked with, market processes. As a result, they don't have the financial potential and incentives to follow job-hoarding strategies. On the other hand, there are almost no SME's which are still stateowned. Hence, the prevailing opinion in the literature is that 'larger industrial firms were apt to be least efficient, most often producing inadequate and non-competitive products, with a high degree ofunder-utilisation oflabour and most inflexible to change' (lones \& Nikolov 1997, p. 252). Thus, as mentioned above, though there may be some limitations with regard to firm representation, our sample characterises a number of enterprises that offer fertile ground for the analysis of firms' adjustment to the newly established market realities in a transition economy. Our study is unique in the sense that existing empirical studies on privatisation and enterprise restructuring generally cover the time period just before and after the initial stages of transition, e.g. 1988/89 to 1992. In those studies, samples of firms in the Czech Republic, Poland, Hungary and Bulgaria recognise that behavioural adaptations at the enterprise level had taken place just before the actual privatisation process materialised. Therefore, almost all of the firms under examination were still state-owned. The firms were usually divided according to their performance as 'good', 'average' and 'bad' enterprises. The main findings of those early studies have shown that the macroeconomic adaptations (i.e., macro-level changes which induced micro-level adjustment by the firms), as well as emerging market structures, have created enormous pressures which in turn have influenced firms' economic behaviour, reallocation of resources and consequent restructuring. This evidence supports the hypothesis that the SOE's started restructuring and adjusting their behaviour and performance, in response to the harsh realities of more open markets, before privatisation actually started. In this paper, we seek to present some results on these developments in Bulgaria, at the later stages of transition and privatisation (1992-1996). The aim of our questionnaire study is therefore to show the effects of the privatisation process and ownership on the behavioural adaptations of firms which had once been state-owned or continue to be owned by the state. The period under investigation is 1992 to 1996. For 1990 and 1991, the number of missing values is reactively high and, where relevant, we partly exclude these observations from our analysis. The paper contains seven sections. Section 11 outlines the macroeconomic environment in which our sample firms operate, provides some specifics of the Bulgarian privatisation process, and discusses data quality. Section 111 concentrates on the analysis of privatisation, the specific forms of ownership that resulted from it, and firm size. In Section IV, we describe the trends of the main economic variables within firms (such as employment, wages, labour productivity, etc), and a number of proxies of firm viability, while Section V presents some regression results to corroborate the discussion of the previous section. Section VI gives an overview of survey results of the impact of enterprise determined wage policy, trade union activity and membership, government control, and social benefits on enterprise restructuring. Section VII is a summary of our findings.}, language = {en} } @book{BakardjievaSowada1999, author = {Bakardjieva, Radostina and Sowada, Christoph}, title = {Privatisation in Bulgaria : strategies, methods, results and conclusions}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-48914}, publisher = {Universit{\"a}t Potsdam}, year = {1999}, abstract = {Privatisation in Central and Eastern Europe can be defined as the transfer of property rights from the State to private owners. The transfers are carried out so as to vest the new private owners with the full property rights of use and disposal over their property, these rights being guaranteed by the legal framework established by the rule of law. In Bulgaria, one can distinguish between three main stages in the process of privatisation. Each was shaped by the conflicting resolutions of frequently changing governments and meant to serve different political goals. The first stage (1990-1993) is characterised by the blockade of legal privatisation, as 'spontaneous privatisation' was accorded high priority. As in other former socialist countries, great emphasis was placed on the so-called commercialisation of state-owned enterprises. This did not involve the actual transfer of State property into private hands, but rather the independent transformation of state-owned enterprises into joint-stock companies, as well as the establishment of subsidiary companies.1 The goals of introducing more efficient structures and applying modern methods of production by transferring property to a more suitable management were not achieved. The second stage (1993-1995) is a cash privatisation, which laid the foundation for an employee/management buy-out, aided by the legal provisions granting concessions in the payment of instalments. The most important factor in the third stage of the process of privatisation in Bulgaria was the adoption of the mass privatisation model as an alternative method of procedure. In 1996, legal regulations for mass privatisation were introduced and a privatisation fund was established. In the meantime, the process has evolved into its fourth stage, during which a strategy of privatisation has been formulated under the supervision of a monetary council, and various agreements with the IMF and the World Bank are being adhered to. Privatisation is the decisive factor in the structural reforms of East European countries. The problem of converting State property into more effective forms of property management has been exacerbated by the additional demand of carrying out the far-reaching structural changes as swiftly as possible. The expectation that a large part of State property would be privatised within a short time in Bulgaria, has not been met for a number of reasons. When the reforms began, the private sector was too weakly developed to become a catalyst for structural changes. Until 1995 there were no laws regulating the stock exchange or securities and bonds - the capital market was practically non-existent. Moreover, the various political parties could not agree upon the various models and objectives of privatisation. The population itself had no capital. The restitution of private ownership which will not be discussed in further detail was limited to the smallest businesses, traders and workshops. Furthermore, the Privatisation Agency and State authorities employed to initiate the privatisation process lacked experience. Another problem hindering privatisation was that the laws passed lacked precision and were constantly subject to change.}, language = {en} } @book{ChristevFitzRoy1999, author = {Christev, Atanas and FitzRoy, Felix}, title = {Employment and wages in transition : panel evidence from Poland}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-48946}, publisher = {Universit{\"a}t Potsdam}, year = {1999}, abstract = {New survey data for a panel of Polish firms is used to estimate employment and wage adjustments under various forms of ownership (insider vs. outsider) and asymmetric response to exogenous shocks.

Results differ from other findings in the transition literature: wages have little effect on dynamic labor demand and the firm-size wage effect is confirmed. Firms that expand employment have to pay significantly larger wage increases and rising sales add little to employment, suggesting labor hoarding.

Previous reports in this area indicated preferable directions of research to be taken in order to prove various hypotheses of the purposefulness of an integral approach to industrial policy and social security in the analysis of economic processes in transition (see Weikard 1997). This paper summarises the results and draws conclusions from a questionnaire study on subsidies, social benefits and economic policy in Polish firms during the process of transformation. Our results and conclusions show the scope and character of the processes in the area of industrial and social policy in the period 1994 to 1997. The paper is divided into five parts. The first part concerns the aims and methodology of the questionnaire; it also gives a brief description of the sample. The second part shows how enterprises dealt with the issues of employment and wages in this period. The third part characterises industrial policy at the corporate level, while the next presents results from the survey of various social schemes pursued. The final part aims at an integral approach in the analysis of various processes taking place in Polish enterprises. The survey was conducted in the period April to June 1998. Its aim was to observe certain phenomena occurring at the corporate level. The questionnaire was distributed among the managers, directors and presidents of large-size enterprises, which had been selected to satisfy the following three criteria. Firstly, the number of employees had to be considerable (over 300 workers). This criterion was applied following the consideration that certain social phenomena are more conspicuous in enterprises with large manpower. Secondly, only operating enterprises were selected, the enterprises which closed down were disregarded. Finally, for the purposes of the survey the units differed as regards their legal situation and form of ownership. Out of over 1800 enterprises 370 units were drawn where we sent the questionnaire. Unfortunately, as many as 51.9\% of the respondents refused co-operation, questions to a certain extent puts the representativeness of the sample in question. Finally, 178 questionnaires were subsequently completed and returned for analysis. However, not all of these questionnaires included full answers to all of the 75 questions; therefore, while discussing the results of the survey we have indicated the number of relevant answers we have received.}, language = {en} } @book{Switlyk1999, author = {Switlyk, Michael}, title = {The economic standing of the partnership companies which lease agricultural real estate from the agricultural property agency of the state treasury in Gorz{\´o}w Voivodeship in 1996 and 1997}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-48858}, publisher = {Universit{\"a}t Potsdam}, year = {1999}, abstract = {The aim of the work was to present the results of the analyses economic standing of the partnership companies which lease agricultural real estate from Agricultural Property Agency of State Treasury (APA) in 1996 and 1997.

Agricultural enterprises can defend their market share only if they are able to adjust quickly and efficiently to new circumstances. The most effective strategy to cope with changing operating conditions is a strategy of permanent development of human resources. This strategy must embrace a constant improvement of professional entrepreneurial skills and of management structures within organizations. Only such a strategy will allow businesses to hold on to or to increase their market standing despite strong competition. It will also allow them to meet, for instance, the newly introduced standardisation procedures for goods produced and supplied. This challenge holds especially true for agricultural enterprises that operate in highly competitive markets; markets which are currently characterised by a permanent surplus of supply over demand and a great number of businesses, mainly of small or medium size. Demand in the agricultural market is exerted by millions of consumers, all of different consumption habits with idiosyncratic consumption preferences. Agricultural producers as a group are extremely sensitive to any kind of change in their environment. This is especially true in the current transition period when a worsening of economic conditions can be observed: an economic downturn caused by the price of inputs increasing at a faster rate than agricultural product prices and an ineffective agricultural policy. One of the agricultural production factors which allows for quick adjustment to change and which can thus be used to improve one's market position is the human factor. It is a wellknown fact that a good level of professional skills in combination with ongoing means of furthering and updating professional qualifications of workers can help to facilitate coping with market challenges. The aim of this study is first to determine specific quality and quantity features of human resources in agricultural production, looking, inter alia, at changes in employment, specific employment structures and the number of recruitments and dismissals in a given period. A further aim was to undertake an efficiency analysis of limited partnerships which leased their agricultural real estate from the Agricultural Property Agency (APA) in the Voivodeship of Gorz{\´o}w between 1995 and 1997. The first analysis was carried out using data which were collected from surveys amongst the owners of 36 privately owned farms and the managers of 14 limited partnerships. The data cover the period between 1994 and 1997. The incentive to conduct research on large farms in the Gorz{\´o}w Voivodeship using the Data Envelopment Analysis method (DEA) lay in the outcome of various earlier studies on the financial standing of limited partnerships leasing real estate from APA in the Gorz{\´o}w Voivodeship in 1996 and 1997. Apart from general adjustment processes, these inquiries proved that, in 1997, the economic condition of the farms analysed was worse when compared to the situation in 1996; the following ratios worsened: the financial support ratio, the liquidity ratio, the turnover ratio, the profitability ratio and the cost level ratio (see Świtłyk, 1998, 1999). These results determined the focus of our research, namely input efficiency in particular limited partnerships. The base of our calculations was a research model which consisted of efficiency measures focusing on firms' inputs The analysis was carried out on a sample of 90 firms in the years between 1995 and 1997 (30 firms every year). Other data material was collected from national statistical office reports on incomes, costs and financial results (F-O1) and statistics about land usage, crop area and yields (R-O5).

Der Hauptzweck dieser Doktorarbeit war es, ein praktisch verwendbares und theoretisch gut fundiertes Modell der Lichtausbreitung in nicht gealterten und gealterten POFs zu entwickeln und es durch optische Experimente zu verifizieren. Dabei wurden anwendungsorientierte Aspekte mit theoretischer POF-Modellierung kombiniert. Die Arbeit enth{\"a}lt die erste bekannte Anwendung der Wellenanalyse zur Untersuchung der winkelabh{\"a}ngigen Eigenschaften der Streuung in Lichtwellenleitern. F{\"u}r die praktischen Experimente wurden mehrere POF-Proben unterschiedlicher Hersteller k{\"u}nstlich gealtert, indem sie bis 4500 Stunden bei 100 °C gelagert wurden (ohne Feuchtekontrolle). Die Parameter der jeweiligen Simulationen wurden mittels einer systematischen Optimierung an die gemessen optischen Eigenschaften der gealterten Proben angeglichen. Die Resultate deuten an, dass der {\"U}bertragungsverlust der gealterten Fasern in den ersten Tagen und Wochen der Alterung am st{\"a}rksten durch eine wesentliche physikalische Verschlechterung der Kern-Mantel-Grenzfl{\"a}che verursacht wird. Chemische Effekte des Alterungsprozesses scheinen im Faserkernmaterial zuerst nach einigen Monaten aufzutreten.}, language = {en} } @book{OPUS4-1006, title = {Three papers on German verb movement}, editor = {Vogel, Ralf}, isbn = {978-3-937786-07-0}, issn = {1864-1857}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-10934}, publisher = {Universit{\"a}t Potsdam}, year = {2004}, abstract = {This volume offers new arguments and perspectives in the ongoing debate about the optimal analysis of verb movement, mainly, but not exclusively, in German. Fanselow and Meinunger deal with verb second (V2) movement in German main clauses. Fanselow argues that head movement of the substitution type follows the standard minimalist conceptions of Merge and Move and is therefore not subject to the same objections as head movement as head adjunction which violates Chomsky's minimalist extension condition, operates countercyclically, and fails to let the moved head c-command its trace. Fanselow argues for V2 movement as head movement of the substitution type. Meinunger discusses a restriction on V2 movement imposed by phrases like "mehr als" ('more than'), as in "Der Wert hat sich weit mehr als verdreifacht" ('the value has far more than tripled') where V2 movement is ruled out (cf. *"Der Wert verdreifachte sich mehr als"). Meinunger claims that this restriction is best analysed in phonological terms: the preposition/complementiser "als" acts as a prefixal clitic to its host, the finite verb, which therefore may not move without it. With respect to the V2 debate, Meinunger argues for an interface perspective. He shows that V2 is restricted from both the conceptual and the phonological interface. Vogel, finally, discusses the syntax of clause-final verbal complexes and their dialectal variation in German. He compares three different syntactic analyses, a minimalist head movement analysis, a minimalist XP movement analysis, and an Optimality theoretic PF movement analysis. The three accounts are evaluated relative to the additional assumptions they have to make, the complications they face and how they fit the observations. Vogel argues in favour of the phonologically oriented OT analysis because of its ability to create a direct link between the coming about of a particular word order pattern and its basically phonological trigger. Each of the three papers recognises the relevance of surface forms in the analysis of German verb movement. They differ, however in the extent to which phonological aspects take part in the explanations they offer.}, language = {en} } @book{OPUS4-506, title = {Leadership and innovation in subnational government : case studies from Latin America}, editor = {Campbell, Tim and Fuhr, Harald}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-5793}, publisher = {Universit{\"a}t Potsdam}, year = {2004}, abstract = {This book is about inventing successes and good practices of governments that are "closer to the people".

However, since automated service composition is a key enabler for the full potential of Service-oriented Architectures, further research on this field is imperative.

Its main elements are the introduction of market liberalization, farm restructuring, privatisation, the reform of the sector and the creation of supporting market institutions and services.1 In this process central state agriculture administration plays a decisive role. This paper is summing up the research of the author on Slovak agricultural administration between 2002 and 2004. This work was part of a DFG-funded research project on "Genesis, Organization and Efficiency of the central-state Ministerial Administration in Central and Eastern Europe". The project was analysing the processes, results and efficiency of administrative structures at central-state level in Estonia, Poland and Slovakia with reference to public administration in the policy fields of agriculture and telecommunications. The paper is reflecting the situation in the sector and its administration at the beginning of 2004. At first, an overview of the role of the agricultural sector in Slovak economy in the past and presence is provided (section I). Against this background, the development of the agricultural policy in the different periods since 1989 will be analysed, mainly what privatisation, accession to the EU and subsidy policy are concerned (section II). A detailed study of the developments in agricultural administration forms the next part of the paper (section III), i.e. the changes taking place in the ministry of agriculture and in the other institutions responsible for the implementation of agricultural policy. The role of interest groups in agriculture is briefly analysed (section IV).

The gradual liberalisation of the Polish telecommunications sector started as early as 1992. In the beginning, national strategies were pursued. The most important of these was the creation of a bipolar market structure in the local area networks. In the second half of the 1990ies the approaching EU membership accelerated the process of liberalisation and consequently the development of a framework of regulations. EU standards are more directed towards setting out a legal framework for regulation than prescribing concrete details of administrative organisation. Nevertheless, the independent regulatory agencies typical for Western Europe served as a model for the introduction of a new regulatory body responsible for the telecommunications sector in Poland. The growing influence of EU legislation changed telecommunications policy as well as administrative practices. There has been a shift of responsibilities from the ministry to the regulatory agency, but the question remains, if the agency gained enough power to fulfil its regulatory function. In the following the legislative framework created by the EU in telecommunications policy will be described and the model of independent regulatory agencies, as it is typical for most EU countries, will be introduced. Some categories for the analysis of the Polish regulatory system will be deduced from the discussion on the regulations of telecommunication in the established EU-Nations (see B{\"o}llhoff 2002 and 2003, Thatcher 2002a and 2002b, Thatcher/Stone Sweet 2002). Subsequently the basic features of Polish telecommunication policies in the 1990ies and its effects on the telecommunications sector will be outlined. In the third chapter the development of organisational structures on the ministerial level and within the regulatory agency will be examined. In the forth chapter I will look at the distribution of power and the coordination of the various authorities responsible for telecommunication regulations.

Confronted with the immense problems of democratic transition, the multi-party governments of Estonia change comparatively often.

A detailed examination of government stability and the example of Estonia is accordingly warranted, given that the country is seen as the most successful Central Eastern European transition country in spite of its frequent changes of government. Furthermore, this article questions whether or not internal government stability can exist within a situation where the government changes frequently. What does stability of government mean and what are the varying multi-faceted depths of the term? Before analysing the term, it has to be clarified and defined. It is presumed that government stability is composed of multiple variables influencing one another. Data about the average tenure of a government is not very conclusive. Rather, the deeper political causes for governmental change need to be examined. Therefore, this article discusses the conceptual and theoretical basics of governmental stability first. Secondly, it discusses the Estonian situation in detail up to the elections of 2003, including a short review of the 9th government since independence.

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.}, language = {en} } @book{MeyerKuropka2005, author = {Meyer, Harald and Kuropka, Dominik}, title = {Requirements for service composition}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-937786-81-0}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-33096}, publisher = {Universit{\"a}t Potsdam}, pages = {27}, year = {2005}, abstract = {1 Introduction 2 Use case Scenario 3 General Composition Requirements 4 Functional Requirements of Service Composition 5 Non-Functional Requirements 6 Conclusion}, 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{OPUS4-2806, title = {Armenia : a human rights perspective for peace and democracy; human rights, human rights education and minorities}, editor = {Mihr, Anja and Mkrtichyan, Artur and Mahler, Claudia and Toivanen, Reetta}, isbn = {978-3-937786-66-7}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-29740}, publisher = {Universit{\"a}t Potsdam}, year = {2005}, abstract = {I.

Moreover, it has been shown that desemanticization, decategorialization, and phonetic erosion are typical characteristics of grammaticalization processes. Not surprisingly, grammaticalization is also responsible for diachronic change in sign languages. Drawing data from a fair number of sign languages, we show that grammaticalization in visual-gestural languages - as far as the development from lexical to grammatical element is concerned - follows the same developmental pathways as in spoken languages. That is, the proposed pathways are modalityindependent.

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.}, language = {en} } @book{Reilich2006, author = {Reilich, Julia}, title = {Return to schooling in Germany}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-12175}, publisher = {Universit{\"a}t Potsdam}, year = {2006}, abstract = {This paper tries to apply common methods to estimate unbiased coefficients for the return to schooling in Germany for the year 2004.

Another explicit goal was to discuss the question whether Minimalism and Optimality Theory should be considered incompatible and, hence, competing theories, or whether the two frameworks should rather be considered complementary in certain respects (see http://let.uvt.nl/deal05/call.html for the call for papers). Five of the seven papers in this volume directly grew out of the oral presentations given at the workshop.

Nonetheless, existing e-learning systems for IT security education have difficulties in delivering hands-on experience because of the lack of proximity. Laboratory environments and practical exercises are indispensable instruction tools to IT security education, but security education in con-ventional computer laboratories poses the problem of immobility as well as high creation and maintenance costs. Hence, there is a need to effectively transform security laboratories and practical exercises into e-learning forms. This report introduces the Tele-Lab IT-Security architecture that allows students not only to learn IT security principles, but also to gain hands-on security experience by exercises in an online laboratory environment. In this architecture, virtual machines are used to provide safe user work environments instead of real computers. Thus, traditional laboratory environments can be cloned onto the Internet by software, which increases accessibilities to laboratory resources and greatly reduces investment and maintenance costs. Under the Tele-Lab IT-Security framework, a set of technical solutions is also proposed to provide effective functionalities, reliability, security, and performance. The virtual machines with appropriate resource allocation, software installation, and system configurations are used to build lightweight security laboratories on a hosting computer. Reliability and availability of laboratory platforms are covered by the virtual machine management framework. This management framework provides necessary monitoring and administration services to detect and recover critical failures of virtual machines at run time. Considering the risk that virtual machines can be misused for compromising production networks, we present security management solutions to prevent misuse of laboratory resources by security isolation at the system and network levels. This work is an attempt to bridge the gap between e-learning/tele-teaching and practical IT security education. It is not to substitute conventional teaching in laboratories but to add practical features to e-learning.

The shapes of homogeneous fluid vesicles and inhomogeneous vesicles with fluid and solid membrane domains are calculated. The influence of thermal fluctuations is investigated. The obtained results are valid on mesoscopic length scales and are based on a geometrical membrane model, where the vesicle membrane is described as either a static or a thermal fluctuating surface. The thesis consists of three parts. In the first part, homogeneous vesicles are considered. The focus in this part is on the thermally induced morphological transition between vesicles with prolate and oblate shape. With the help of Monte Carlo simulations, the free energy profile of these vesicles is determined. It can be shown that the shape transformation between prolate and oblate vesicles proceeds continuously and is not hampered by a free energy barrier. The second and third part deal with inhomogeneous vesicles which contain intramembrane domains. These investigations are motivated by experimental results on domain formation in single or multicomponent vesicles, where phase separation occurs and different membrane phases coexist. The resulting domains differ with regard to their membrane structure (solid, fluid). The membrane structure has a distinct effect on the form of the domain and the morphology of the vesicle. In the second part, vesicles with coexisting solid and fluid membrane domains are studied, while the third part addresses vesicles with coexisting fluid domains. The equilibrium morphology of vesicles with simple and complex domain forms, derived through minimisation of the membrane energy, is determined as a function of material parameters. The results are summarised in morphology diagrams. These diagrams show previously unknown morphological transitions between vesicles with different domain shapes. The impact of thermal fluctuations on the vesicle and the form of the domains is investigated by means of Monte Carlo simulations.}, language = {en} } @book{OPUS4-1329, title = {Interdisciplinary studies on information structure : ISIS ; Working papers of the SFB 632. - Vol. 8}, editor = {Ishihara, Shinichiro and Jannedy, Stefanie and Schwarz, Anne}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-939469-72-8}, issn = {1866-4725}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-14359}, publisher = {Universit{\"a}t Potsdam}, pages = {230}, year = {2007}, abstract = {The 8th volume of the working paper series Interdisciplinary Studies on Information Structure (ISIS) of the SFB 632 contains a collection of eight papers contributed by guest authors and SFB-members. 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 l{\´e} and l{\´a} of the language, she argues that l{\´e} 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 K{\"u}gler, 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.

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.

Recent research has considered the use of relationships among object representations to improve duplicate detection. In the general case where relationships form a graph, research has mainly focused on duplicate detection quality/effectiveness. Scalability has been neglected so far, even though it is crucial for large real-world duplicate detection tasks. In this paper we scale up duplicate detection in graph data (DDG) to large amounts of data and pairwise comparisons, using the support of a relational database system. To this end, we first generalize the process of DDG. We then present how to scale algorithms for DDG in space (amount of data processed with limited main memory) and in time. Finally, we explore how complex similarity computation can be performed efficiently. Experiments on data an order of magnitude larger than data considered so far in DDG clearly show that our methods scale to large amounts of data not residing in main memory.}, language = {en} } @book{Lang2008, author = {Lang, Thilo}, title = {Institutional perspectives of local development in Germany and England : a comparative study about regeneration in old industrial towns experiencing decline}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-37346}, publisher = {Universit{\"a}t Potsdam}, year = {2008}, abstract = {This research is about local actors' response to problems of uneven development and unemployment. 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. Until now, most urban governance studies have analysed the impacts of particular forms of governance such as regeneration partnerships. This project looks at particular initiatives and poses the question to what extent their emergence can be understood as a result of particular forms of governance, local institutional factors or regional and national contexts.}, language = {en} } @book{PolyvyanyySmirnovWeske2008, author = {Polyvyanyy, Artem and Smirnov, Sergey and Weske, Mathias}, title = {The triconnected abstraction of process models}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-940793-65-2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-32847}, publisher = {Universit{\"a}t Potsdam}, pages = {17}, year = {2008}, abstract = {Contents: Artem Polyvanny, Sergey Smirnow, and Mathias Weske The Triconnected Abstraction of Process Models 1 Introduction 2 Business Process Model Abstraction 3 Preliminaries 4 Triconnected Decomposition 4.1 Basic Approach for Process Component Discovery 4.2 SPQR-Tree Decomposition 4.3 SPQR-Tree Fragments in the Context of Process Models 5 Triconnected Abstraction 5.1 Abstraction Rules 5.2 Abstraction Algorithm 6 Related Work and Conclusions}, language = {en} } @book{OPUS4-3118, title = {Proceedings of the 2.

In case of dynamic collaborations the roles may join and leave the collaboration at runtime and therefore complex structural dynamics can result, which makes it very hard to ensure their correct and safe operation. We present in this paper our approach for modeling and verifying such dynamic collaborations. Modeling is supported using a well-defined subset of UML class diagrams, behavioral rules for the structural dynamics, and UML state machines for the role behavior. To be also able to verify the resulting service-oriented systems, we extended our former results for the automated verification of systems with structural dynamics [7, 8] and developed a compositional reasoning scheme, which enables the reuse of verification results. We outline our approach using the example of autonomous vehicles that use such dynamic collaborations via ad-hoc networking to coordinate and optimize their joint behavior.}, language = {en} } @book{RolfesSteinbrinkUhl2009, author = {Rolfes, Manfred and Steinbrink, Malte and Uhl, Christina}, title = {Townships as attraction : an empirical study of township tourism in Cape Town}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-940793-79-9}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-28947}, publisher = {Universit{\"a}t Potsdam}, pages = {60}, year = {2009}, abstract = {Since the end of the Apartheid international tourism in South Africa has increasingly gained importance for the national economy.

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.
