For the efficient management of large image databases, the automated characterization of images and the usage of that characterization for searching and ordering tasks is highly desirable. The purpose of the project SEMACODE is to combine the still unsolved problem of content-oriented characterization of images with scale-invariant object recognition and modelbased compression methods. To achieve this goal, existing techniques as well as new concepts related to pattern matching, image encoding, and image compression are examined. The resulting methods are integrated in a common framework with the aid of a content-oriented conception. For the application, an image database at the library of the university of Frankfurt/Main (StUB; about 60000 images), the required operations are developed. The search and query interfaces are defined in close cooperation with the StUB project “Digitized Colonial Picture Library”. This report describes the fundamentals and first results of the image encoding and object recognition algorithms developed within the scope of the project.
The prevention of credit card fraud is an important application for prediction techniques. One major obstacle for using neural network training techniques is the high necessary diagnostic quality: Since only one financial transaction of a thousand is invalid no prediction success less than 99.9% is acceptable. Due to these credit card transaction proportions complete new concepts had to be developed and tested on real credit card data. This paper shows how advanced data mining techniques and neural network algorithm can be combined successfully to obtain a high fraud coverage combined with a low false alarm rate.
A tale of two lost archives
(2009)
This paper surveys the growth and various phases of and influences on the concept of democracy in the Islamic political thought of the last two centuries. Among the thinkers covered in the survey are Rifa'a Tahtawi (1801-73), Khairuddin at-Tunis (1810-99), Jamal ad-Din al-Afghani (1838-97), Muhammad Abduh (1849-1905), Abdurrahman al-Kawakibi (1849-1903), Rashid Rida (1865-1935), Hasan al-Banna (1904-49), Ali Abd Ar-Raziq (1888-1966), Sayyid Qutb (1906-66), Sa'id Hawwa, and Malik Bennabi (1905-73). Reference is made to the influence of Sayyid Mawdudi (1903-79), on the thought of Sayyid Qutb. The paper traces also the bearing of Bennabi's thought on Rachid Ghannouchi and on the Islamic movements of our times.
Quantificational determiners in Japanese can be marked with genitive case. Current analyses (for example by Watanabe, Natural Language and Linguistic Theory, to appear) treat the genetive case marker in these cases as semantically vacuous, but we show that it has semantic effects. We propose a new analysis as reverse partitives. Following Jackendoff (MIT-Press, 1977), we assume that partitives always contain two NPs one of which is phonologically deleted. We claim that, while in normal partitives the higher noun is deleted, in reverse partitives the lower noun is deleted.

In late 2006/early 2007, the Cultural Research Centre (CRC), with financial and technical support from the Cross-Cultural Foundation of Uganda, carried out research in Iganga and Namutumba districts to gauge the impact of the introduction of the local language as a medium of instruction in ‘pilot’ lower primary school classes. Our research was in response to new circumstances in Uganda’s education sector, with Government introducing teaching in local languages in lower primary classes from February 2007. This was accompanied by a “thematic curriculum”, to develop early childhood skills that are fundamental to continuing educational performance in numeracy, literacy and life skills. This was a departure from the earlier emphasis on the acquisition of facts in various subjects in primary schools, mostly focusing on recall, and mostly taught in English. This nationwide policy followed a pilot initiative in four districts, including Iganga (later split into Iganga and parts of Namutumba districts), where 15 pilot schools had been chosen. Instruction in Lusoga in Primary 1 to 3 classes started there in 2005, following a period of teacher training. From the outset however, parents, teachers, pupils and others raised questions: was teaching in the local language possible, and would it make a positive difference to learning?
In Lango, Northern Uganda, 20 years of war, cattle rustling and HIV/AIDS have resulted in widespread loss of life, population displacement, and loss of property. In spite of this turmoil, some traditional cultural practices, such as widow inheritance, early child marriage, and widow cleansing continued, although they were increasingly seen to conflict with ‘modern’ development thinking, especially when infringing women and children’s rights. External development actors first tried to address this situation by ‘sensitising’ communities, but with limited success. It however soon became evident that clan leaders were instrumental in perpetuating cultural practices: in the early 2000’s, they became increasingly identified as key actors to address harmful traditions and to resolve conflicts. With the many trials faced by local communities, women’s roles in supporting the family institution and upholding cultural values had however expanded too. Several development organisations were established to address the challenges related to these changes and one was the Lango Female Clan Leaders’ Association, with a focus on promoting girls’ education and access to justice for women. This case study examines the role that these female clan leaders have successfully played in tackling current gender- related challenges. It explores the interface between traditional and modern gender concepts and the value of working with cultural resource persons to address cultural challenges. The study involved desk research, field based semistructure interviews, focus group discussions with 30 respondents and key informants, and a validation write-shop, all held in the course of 2008.
A remarkable indictment and conviction following the sale of an ‘obscene’ comic book invites us to examine arguments brought forth to describe a specifically childlike reception of new media, as usually suggested by those who would motivate legal restrictions for such media. Trying to explain some perceived contradictions on the surface of these arguments, we discuss whether it is the failure or rather the extreme success of texts that is marked as ‘dangerous’ in such contexts.
The main goal of this article is to define the problem of vowel duration in Civili (H12a). It shows that the so-called Civili vowel-length desperately needs to be re-examined, because previous works on the sound system of this language hardly explain a number of phonological phenomena, such as vowel lengthening, on the basis of data at hand. Demonstrating the problem in question, the author first reviews previous works that all identify a vowel lengthening in Civili. From different analyses the complexity of the phenomenon is found out by observing differences from an analysis to another, and by regarding difficulties the different phonologists came up against. Then, the problem is also seen through the weakness of each analysis results. This eventually shows more aspects of the vowel duration issue, and leads the author to make a clear distinction between vowel length and vowel lengthening that can be all regarded as only vowel duration. Finally, the article shares a possible way for a solution through an experimental approach of the Civili sound system.

This review describes how the constraints of limited water resources and an arid and semi-arid environment were overcome by a leadership capable of defining future needs and identifying and implementing appropriate solutions. Advanced technologies proved indispensable in this process. Yet, in recent years, the continuously increasing demand for water, mainly for domestic use, has created a chronic situation in which all available water from natural sources is being used up. The only solution to ensuring a dependable supply of water for both domestic and agricultural use requires that several steps be taken concurrently to implement regulations and measures for saving water and to construct immediately large-scale plants for desalination of seawater and reclamation of urban effluents.

Jan Snyman papers
(2007)
Biographical history and context: Professor Jan Snyman spent most of his life researching the lesser known and marginalised San languages of Botswana and South West Africa (now Namibia). Together with O. Kohler, E. Westphal and A. Traill, he pioneered linguistic studies on these endangered languages of Africa. He contributed significantly in collection of the data that helped classify and understand the grammar of San languages. Snyman also wrote several grammars in the form of monographs and notes on these languages. By the time he died, in 2002, a draft for the Tshwaa and Kua languages had been completed. Content: Linguistic, phonetics and orthography research materials including fonts for phonetic languages. Covering dates: 1967-2000
In this paper I argue in favor of a Matching Analysis for German relative clauses. The Head Raising Analysis is shown to fail to account for parts of the reconstruction pattern in German, especially cases where only the external head is interpreted and the absence of Principle C effects. I propose a Matching Analysis with Vehicle Change and make consistent assumptions about possible deletion operations in relatives so that the entire pattern can be captured by one analysis which therefore proves superior to previous ones.
In April 2002 the European Central Bank (ECB) and the Center for Financial Studies (CFS) launched the ECB-CFS Research Network to promote research on “Capital Markets and Financial Integration in Europe”. The ECB-CFS research network aims at stimulating top-level and policy-relevant research, significantly contributing to the understanding of the current and future structure and integration of the financial system in Europe and its international linkages with the United States and Japan. This report summarises the work done under the network after two years. Over time the network formed a coherent and growing group of researchers interested in the integration of European financial markets, while using light organisational structures and budgets. The members of this evolving group met repeatedly at the events organised by the network to present the latest results of their research and to share views on policy options. In this sense, the “network of people” intended at the start was created. Overall, the network aroused great interest, as leading academic researchers, researchers from the main policy institutions and high-level policy makers participated actively in it by presenting research results, through speeches and in policy panels. It also stimulated a new research field on securities settlement systems, an area of high policy relevance and interest to the ECB that had not attracted much interest in the research community beforehand. Also, the network seems to have triggered several related outside initiatives by international institutions, such as the IMF or the OECD. During its first two years the network was organised around three workshops and a final symposium on 10-11 May 2004. To focus research resources and to ensure medium-term policy relevance, a limited number of areas have been given top priority: bank competition and the geographical scope of banking; international portfolio choices and asset market linkages between Europe, the United States and Japan; European bond markets; European securities settlement systems; and the emergence and evolution of new markets in Europe (in particular start-up financing markets). In order to stimulate further research focused on the priority fields of the network, the ECB Lamfalussy research fellowships were established. These fellowships sponsor projects proposed by young researchers, both a dvanced doctoral students and younger professors. Five Lamfalussy fellowships were granted in 2003 and five more in 2004. The first papers from this program have already been issued in the ECB working paper series or are forthcoming. One of them won the prize for the best paper written by a Ph.D. student at the 2004 European Finance Association Meetings in Maastricht. Results of the network in the five top priority areas can be summarised as follows: Bank competition and the geographical scope of banking. First, integration does not appear to be very advanced in many retail banking markets. Second, some of the inherent characteristics of traditional loan and deposit business constrain the cross-border expansion of commercial banking, even in a common currency area. Hence, the implementation of some policies to foster cross-border integration in retail banking may be ineffective. Third, theoretical research suggests that supervisory structures may not be neutral towards further European banking integration. Finally, a stronger role of area-wide competition policies could be beneficial for further banking integration. This would also stimulate economic growth, as more competition in the banking sector induces financially dependent firms to grow more. European bond markets. While the government bond market has integrated rapidly with the EMU convergence process, its full integration has not yet been achieved. The introduction of a common electronic trading platform reduced transaction costs substantially, but yield spreads of long-term sovereign bonds of the euro area are still heterogeneous. This is largely explained by different sensitivities to an international risk factor, whereas liquidity differentials only play a role in conjunction with this latter factor. Somewhat surprisingly in this context, the dynamically developing corporate bond market exhibits a relatively high level of integration. There is also increasing evidence that the introduction of the euro has contributed to a reduction in the cost of capital in the euro area, in particular through the reduction of corporate bond underwriting fees. As a result, firms may wish to increase bond financing relative to equity financing. The development of a larger corporate bond market is also important for monetary policy. For example, US evidence suggests that the rating of corporate bonds may contribute to the persistence of recessions, as rating agencies´ policies affect firms asymmetrically in their access to the bond market over the business cycle. US evidence also suggests that liquidity conditions in stock and bond markets tend to be positively correlated. European securities settlement systems. European securities settlement infrastructures are highly fragmented and further integration and/or consolidation would exploit economies of scale that could greatly benefit investors. It is not clear, however, whether direct public intervention in favour of consolidation would lead to the highest level of efficiency, for example because of the existence of strong vertical integration between trading and securities platforms (“silos”). In contrast, promoting open access to clearing and settlement systems could lead to consolidation and the highest level of efficiency. Finally, regarding concerns about unfair practices by Central Securities Depositories (CSDs) toward custodian banks, regulatory interventions favouring custodian banks should be discouraged, as long as CSDs are not allowed to price discriminate between custodian banks and investor banks. The emergence and evolution of new markets in Europe (in particular start-up financing markets). While fairly well integrated, “new markets” and start-up financing are less developed and integrated in Europe than in the United States. However, new markets and venture capitalists are the most important intermediaries for the financing of projects with high risk but with potentially very high return. The analysis carried out within the network reveals that European start-up financiers are mostly institutional investors, while US venture capitalists are mostly rich individuals. Also, new markets are essential for the development of start-up finance in Europe, as they provide an exit strategy for start-up financiers who can then sell new successful projects using initial public offerings. Finally, the legal framework affects the development of venture capital firms. For example, very strict personal bankruptcy laws constrain early stage entrepreneurs, reducing demand for venture capital finance. International portfolio choices and asset market linkages between Europe, the United States and Japan. At a global scale, asset market linkages have increased recently. For example, major economies such as the United States and the euro area have become more financially interdependent. This phenomenon can be observed in stock and bond markets as well as in money markets, where the main direction of spillovers has recently been from the US to the euro area. Country-specific shocks now play a smaller role in explaining stock return variations of firms whose sales are internationally diversified. Increases in firmby-firm market linkages are a global phenomenon, but they are stronger within the euro area than in the rest of the world. Various other phenomena also increase market linkages and therefore the likelihood that financial shocks spread across countries. One example is the use of global bonds. Finally, the nowadays more direct access of unsophisticated investors to financial markets may increase volatility. Other areas. Financial integration affects financial structures, but it does not need to lead to their convergence across countries. Financial structures matter for growth, as market-oriented financial systems benefit all sectors and firms, whereas bank-based systems primarily benefit younger firms that depend on external finance. Moreover, good corporate governance increases firms’ value. In particular, the dual board system, where the monitoring and advising roles of the board of directors are separated, is found to dominate the single board structure. Therefore, the further development of the European single market should strongly require good corporate governance. In general, well designed institutions foster entrepreneurial activity, partly by relaxing capital constraints. The results of the network clearly illustrated the substantial effects the introduction of the euro had on euro area financial markets. In addition to the effects on bond markets, stock markets and the cost of capital summarised above, research produced showed that the single currency had its strongest effects on money markets, whose unsecured segment is now completely integrated. Without any doubt the euro generally enhanced the liquidity and efficiency of euro area financial markets, and ongoing initiatives such as the European Union’s Financial Services Action Plan will help to continue this process. In sum, in the first two years the network has established itself as the hub for the research debate on European financial integration. Some of the best papers produced by the network, leading to the conclusions mentioned above, are currently being considered for publication in two special issues of academic journals. An issue of the Oxford Review of Economic Policy on “European financial integration” is published contemporaneously with this report, and an issue of the Review of Finance is planned for next year. The current policy context, the gradual progress of integration as well as the creation of other related non-ECB or non-CFS initiatives on financial integration suggest that this topic will remain high on the agendas of policy makers and academics for the years to come. Therefore, the ECB Executive Board and the CFS decided to continue the network, refocusing its priorities. Three priority areas have been added: 1) The relationship between financial integration and financial stability, 2) EU accession, financial development and financial integration, and 3) financial system modernisation and economic growth in Europe. These three areas have become particularly important at the current juncture, but have not received particularly strong attention in the first two years of the network. For example, the area of financial stability research was highlighted by the ECB research evaluators as an area deserving further development. Moreover, despite the results found in the first two years of the network, new developments remain to be further explored in the earlier priority areas. A three-year extension is envisaged, running from after the May 2004 symposium until 2007, with two events to be held per year. The threeyear period is long enough to consider the first effects of the Financial Services Action Plan. It also constitutes a realistic horizon for the ambitious agenda implied by the three new priorities. The generally light organisational structure and working of the network will not be changed. In addition, given the value of the Lamfalussy fellowship research program in inducing further research in the areas of the network, the program has also been extended for all the research topics in the area of the network.

Bency Eichorn learns in kollel and, on the side, has been researching about various segulos. For his wedding he authored a book, Simchas Zion, discussing the segulah of keeping the afikomom from year-to-year. The post below is a small part of a much larger project on this segulah and has been adapted for the blog.
Exploring elites and their relations to institutions can assist understanding the day-to-day realities of politics in Africa (Chabal and Daloz 1999, Amundsen 2001, Lindberg 2003). This review is a scoping exercise in what has been written on the subject in recent years. The main task of the review is to summarise current understandings of how elites work with and through political institutions in Africa. There is a huge literature in this subject area. We have tried to pick out a) that which is most pertinent and non-repetitive, and b) that which raises as many questions as it provides answers. On the whole we have focused on literature published in the last five to ten years and we have inclined towards the literature on Anglophone Africa. The review is presented as follows: Section 1 is an introduction to Africa’s recent political landscape and it introduces some of the major issues that appear in the literature. Section 2 provides some working definitions of elites, institutions and democratisation as three of the recurring themes in the review. Section 3 reviews literature broadly on democratisation in Africa and specifically on elections and elites. Section 4 examines how political parties have evolved over the last 15 years. Section 5 reviews the three branches of government and Section 6 briefly examines decentralisation and its relation to elites and politics. The remaining sections of the review move outside the more formal political structures to examine the media (Section 7), civil society (Section 8), women’s movements (Section 9), Trades unions (Section 10) and business associations (Section 11). The final Section 12 pulls out a number of gaps in the research that we have identified in the course of the review. Section 13 contains a complete bibliography of citations used in the review. It is crucial to remember that Africa’s experiences of democratisation are no more than 15 years old, and many scholars have cautioned that it is still very early to draw any definite conclusions (Amundsen 2001; Randall and Svasand 2002).

The basic problem of primary audio and video research materials is clearly shown by the survey: A great and important part of the entire heritage is still outside archival custody in the narrower sense, scattered over many institutions in fairy small collections, and even in private hands. reservation following generally accepted standards can only be carried out effectively if collections represent critical mass. Specialised audiovisual archives will solve their problems, as they will sooner or later succeed in getting appropriate funding to achieve their aims. A very encouraging example is the case of the Netherlands. The larger audiovisual research archives will also manage, more or less autonomously, the transfer of contents in time. For a considerable part of the research collections, however, the concept of cooperative models and competence centres is the only viable model to successfullly safeguard their holdings. Their organisation and funding is a considerable challenge for the scientific community. TAPE has significantly raised awareness of the fact that, unless action is swiftly taken, the loss of audiovisual materials is inevitable. TAPE’s international and regional workshops were generally overbooked. While TAPE was already underway, several other projects for the promotion of archives have received grants from organisations other than the European Commission, inter alia support for the St. Petersburg Phonogram Archive, and the Folklore Archive in Tirana, obviously as a result of a better understanding of the need for audiovisual preservation. When the TAPE project started its partners assumed that cooperative projects would fail because of the notorious distrust of researchers, specifically in the post-communist countries. One of the most encouraging surprises was to learn that, at least in the most recent survey, it became apparent that this social obstacle is fading out. TAPE may have contributed to this important development.
This article generalizes Schwinger’s mechanism for particles production in the arbitrary finite field volume. McLerran-Venugopolan(MV) model and iterative solution of DGLAP equation in the double leading log approximation for small x gluon distribution function were used to derive the new formula for initial chromofield energy density. This initial chromofield energy is distributed among color neutral clusters or strings of different length. This strings are stretched by receding nucleus. From the proposed mechanism of string fragmentation or color field decay based on exact solution of Dirac equation in the different finite volume, the new formulae for esimated baryon kinetic energy loss and rapidity spectrum of produced partons were derived.
In the article, a travel sketch of Danish playwright Kaj Munk (1898 – 1944) is analytically considered. The analysis of this text allows drawing at least three conclusions: 1. Explicit motive of seasickness, figuring here as antithetic modification of implicite present free-standing posture motive, symbolizes idea of disintegrating personality. 2. Such a symbolism is deeply rooted in that of Danish identity. 3. From literary styles and trends history point of view, the sketch appears to be typical of that line in expressionism, which continues tradition of symbolism as artistic and literary trend of late 19th century.
When one considers the results of social scientific surveys, secularisation in Germany seems to be a more or less linear process of erosion of what is traditionally named religiosity. The percentage of citizens who affirm that they are “religious”, believe in God or otherworldly beings, hope for life after death or participate regularly in the praxis of a religious community has been – by and large – steadily declining for decades. This decline has occurred over the succeeding generations: The younger the generation, the fewer “religious” people in it. But the process of secularisation is apparent not only in this persistent quantitative shrinkage from generation to generation. Above all it also manifests itself – this is the thesis of the article – in the transformation of the habitus formations and contents of faith of the generations. The essence of ongoing secularisation naturally is reflected most clearly in its contemporary state of development which is represented in the youngest adult generation. Therefore the analysis of this generation is particularly interesting for the sociology of religion. But the article does not confine to analyze this generation. After indicating some basic premises of the sociology of generations and the notion of secularisation presupposed in this paper, the succession of generations in Germany is outlined hypothetically, from the so-called generation of ´68 to the youngest adult generation, concluding with some remarks about the progress of secularisation.
This paper documents the experiences of assurance evaluation during the early stage of a large software development project. This project researches, contracts and integrates privacy-respecting software to business environments. While assurance evaluation with ISO 15408 Common Criteria (CC) within the certification schemes is done after a system has been completed, our approach executes evaluation during the early phases of the software life cycle. The promise is to increase quality and to reduce testing and fault removal costs for later phases of the development process. First results from the still-ongoing project suggests that the Common Criteria can define a framework for assurance evaluation in ongoing development projects.
We review arguments for and against reserve requirements and conclude that the main question is whether a distinction between money creation and intermediation can be made. We argue that such a distinction can be made in a money-in-advance economy and show that if the money-in-advance constraint is universally binding then reserve requirements on checkable accounts have no effect on intermediation. We then proceed to show that in a model in which trade is uncertain and sequential, a fractional reserve banking system gives rise to endogenous monetary shocks. These endogenous monetary shocks lead to fluctuations in capacity utilisation and waste. When the money-in-advance constraint is universally binding, a 100% reserve requirement on checkable accounts can eliminate this waste.
