Die vorliegende Arbeit geht unmittelbar vom Konzept der Natürlichen Morphologie aus. Am Datenbereich der dt. Substantivflexion soll die explanative Adäquatheit und Prädiktabilität des Konzepts hinsichtlich des Aufbaus und der Veränderung eines Teilflexionssystems als Ganzes überprüft und auf dieser Basis ein Strukturmodell der dt. Substantivflexion vorgeschlagen werden. Insbesondere bei der Erfassung der Gesamtstruktur des Teilflexionssystems werden dabei Probleme des zugrundegelegten theoretischen Ansatzes deutlich werden. Mit der Diskussion und der Überprüfung theoretischer Annahmen, die diese Probleme lösen können, sowie der detaillierten Analyse des Flexionsverhaltens der dt. Substantive soll ein Beitrag zur weiteren Ausformulierung des in eine allgemeine Präferenztheorie einzuordnenden theoretischen Konzepts der Natürlichen Morphologie wie auch zur germanistischen Forschung geleistet werden.
The paper analyses the effects of three sets of accounting rules for financial instruments - Old IAS before IAS 39 became effective, Current IAS or US GAAP, and the Full Fair Value (FFV) model proposed by the Joint Working Group (JWG) - on the financial statements of banks. We develop a simulation model that captures the essential characteristics of a modern universal bank with investment banking and commercial banking activities. We run simulations for different strategies (fully hedged, partially hedged) using historical data from periods with rising and falling interest rates. We show that under Old IAS a fully hedged bank can portray its zero economic earnings in its financial statements. As Old IAS offer much discretion, this bank may also present income that is either positive or negative. We further show that because of the restrictive hedge accounting rules, banks cannot adequately portray their best practice risk management activities under Current IAS or US GAAP. We demonstrate that - contrary to assertions from the banking industry - mandatory FFV accounting adequately reflects the economics of banking activities. Our detailed analysis identifies, in addition, several critical issues of the accounting models that have not been covered in previous literature. December 2002. Revised: June 2003. Later version: http://publikationen.ub.uni-frankfurt.de/volltexte/2005/1026/ with the title: "Accounting for financial instruments in the banking industry : conclusions from a simulation model"
Recent empirical studies on the inflation-growth-relationship underline that inflation has negative growth effects already under relatively modest rates. Most contributions to monetary growth theory, however, have difficulties in explaining such a pattern. It is shown in this paper that this problem can be overcome by establishing a link between monetary instability and the aggregate elasticity of factor substitution. Several microeconomic justifications can be found for a negative influence of inflation on factor substitution. It turns out that already in a simple neoclassical monetary growth model this effect is usually strong enough to question the superneutrality benchmark result in the steady state and to dominate all potential positive effects of inflation along the convergence path. In a more general perspective the paper contributes to a better integration of institutional change in aggregate models of economic growth.

This paper determines the cost of employee stock options (ESOs) to shareholders. I present a pricing method that seeks to replicate the empirics of exercise and cancellation as good as possible. In a first step, an intensity-based pricing model of El Karoui and Martellini is adapted to the needs of ESOs. In a second step, I calibrate the model with a regression analysis of exercise rates from the empirical work of Heath, Huddart and Lang. The pricing model thus takes account for all effects captured in the regression. Separate regressions enable me to compare options for top executives with those for subordinates. I find no price differences. The model is also applied to test the precision of the fair value accounting method for ESOs, SFAS 123. Using my model as a reference, the SFAS method results in surprisingly accurate prices.

This paper studies one of the earliest forms of modern consumer culture—the road book—in relation to one of the early utopias of modern consumption—California. Criticism has traditionally treated the road book as an extension of a loosely defined transcendentalist project, where drivers take to the open road to “discover” themselves in nature. The determinate context, however, is corporate rather than literary-historical. The earliest road books were advertisements. Their itineraries linked up with other spatial technologies (e.g. the conveyor belts in automobile plants and modern highways), transforming space into a vast production and distribution network. Production and distribution intersected in California, the state with the most automobiles per capita and the destination of most early road trips.
The first section of the paper considers the journey to California from the perspective of Emily Post, who would later become a famous writer on etiquette. Post’s book is the narrative equivalent to the standardized roadside architecture, converting local difference into a tourist attraction, and local (especially ethnic) identity into a commodity. The next section considers the effects of commercial homogenization on gender, focusing on the moment when some women, taking the steering wheel, assumed agency as consumers. The primary texts here are some of the early novels of Sinclair Lewis, along with examples of sociology and advertising copy from the 1920s and 1930s. The final section analyzes the WPA Guidebook to California as a federal attempt to re-map corporate space—the space of tourist attractions and consumers—according to a progressive ideal. All three sections treat the tour form as a spatial and literary structure—a privileged topos, at once geographical and symbolic, where complex relations between identity and place are negotiated in the form of a journey.
This paper uses the co-incidence of extreme shocks to banks’ risk to examine within country and across country contagion among large EU banks. Banks’ risk is measured by the first difference of weekly distances to default and abnormal returns. Using Monte Carlo simulations, the paper examines whether the observed frequency of large shocks experienced by two or more banks simultaneously is consistent with the assumption of a multivariate normal or a student t distribution. Further, the paper proposes a simple metric, which is used to identify contagion from one bank to another and identify “systemically important” banks in the EU.
Open-end real estate funds (so called “Offene Immobilienfonds”) play a major role in the German market for securitised real estate investments. Such funds are pools of money from many investors, which are invested in real estate by special investment management companies. This study seeks to identify the risk and return profile of this investment vehicle (before and after income taxes), to compare them with those of other major asset classes, and to provide implications for their appropriate role in a mixed-asset portfolio. Addition-ally, an overview of the institutional architecture and role of German open-end real estate funds is given. Empirical evidence suggests that the financial characteristics of open-end real estate funds are in many respects similar to those reported for direct real estate invest-ments. Accordingly, German open-end real estate funds qualify for medium and long-term investment horizons, rather than for shorter holding periods.
The classical approaches to asset allocation give very different conclusions about how much foreign stocks a US investor should hold. US investors should either allocate a large portion of about 40% to foreign stocks (which is the result of mean/variance optimization and the international CAPM) or they should hold no foreign stocks at all (which is the conclusion of the domestic CAPM and mean/variance spanning tests). There is no way in between.
The idea of the Bayesian approach discussed in this article is to shrink the mean/variance efficient portfolio towards the market portfolio. The shrinkage effect is determined by the investor's prior belief in the efficiency of the market portfolio and by the degree of violation of the CAPM in the sample. Interestingly, this Bayesian approach leads to the same implications for asset allocation as the mean-variance/tracking error criterion. In both cases, the optimal portfolio is a combination of the market portfolio and the mean/variance efficient portfolio with the highest Sharpe ratio.
Applying both approaches to the subject of international diversification, we find that a substantial home bias is only justified when a US investor has a strong belief in the global mean/variance efficiency of the US market portfolio and when he has a high regret aversion of falling behind the US market portfolio. We also find that the current level of home bias can be justified whenever-regret aversion is significantly higher than risk aversion.
Finally, we compare the Bayesian approach of shrinking the mean/variance efficient portfolio towards the market portfolio to another Bayesian approach which shrinks the mean/variance efficient portfolio towards the minimum-variance portfolio. An empirical out-of-sample study shows that both Bayesian approaches lead to a clearly superior performance compared to the classical mean/variance efficient portfolio.
This paper evaluates the effects of job creation schemes on the participating individuals in Germany. Since previous empirical studies of these measures have been based on relatively small datasets and focussed on East Germany, this is the first study which allows to draw policy-relevant conclusions. The very informative and exhaustive dataset at hand not only justifies the application of a matching estimator but also allows to take account of threefold heterogeneity. The recently developed multiple treatment framework is used to evaluate the effects with respect to regional, individual and programme heterogeneity. The results show considerable differences with respect to these sources of heterogeneity, but the overall finding is very clear. At the end of our observation period, that is two years after the start of the programmes, participants in job creation schemes have a significantly lower success probability on the labour market in comparison to matched non-participants.

Past research suggests that international real estate markets show return characteristics and interrelationships with other asset classes, which probably qualify them as an interesting component of national and international asset allocation decisions. However, the special characteristics of real estate assets are quite distinct from that of financial assets, such as stocks and bonds. This is also the case for real estate return distributions. Therefore, the proper integration of real estate markets into asset allocation decisions requires profound understanding of real estate returns' distributional characteristics .
Because of the particular characteristics of real estate, representing real estate markets through reliable a time-series is a complex task. Consequently, reliable real estate indices with a sufficiently long history in major international real estate markets are only scarcely available. Most of the research that has been done on real estate returns was done for the U.K. and U.S., where eligible indices exist. On the other hand, in other important real estate markets, such as Germany, either little or no research has been perfoimed.
In this analysis, the methodology of Maurer, Sebastian and Stephan (2000) for indirectly deriving an appraisal-based index for the German commercial real estate market will be applied. This approach is solely based on publicly available data from German open-ended real estate investment trusts. It could also provide a solution to deriving a reliable real estate time-series for other markets.
We will extend previous analyses for the U.K. and U.S. to provide additional fundamental insights into the return characteristics of the German commercial real estate market. Despite univariate considerations, the main focus is the interrelationships between various international real estate markets, as well as between those respective markets and the international stock and bond markets.
As past research suggest, currency exposure risk is a main source of overall risk of international diversified portfolios. Thus, controlling the currency risk is an important instrument for controlling and improving investment performance of international investments. This study examines the effectiveness of controlling the currency risk for international diversified mixed asset portfolios via different hedge tools. Several hedging strategies, using currency forwards and currency options, were evaluated and compared with each other. Therefore, the stock and bond markets of the, United Kingdom, Germany, Japan, Switzerland, and the U.S, in the time period of January 1985 till December 2002, are considered. This is done form the point of view of a German investor. Due to highly skewed return distributions of options, the application of the traditional mean-variance framework for portfolio optimization is doubtful when options are considered. To account for this problem, a mean-LPM model is employed. Currency trends are also taken into account to check for the general dependence of time trends of currency movements and the relative potential gains of risk controlling strategies.
This chapter focuses on institutional investors in the German financial markets. Institutional investors are specialized financial intermediaries who collect and manage funds on behalf of small investors toward specific objectives in terms of risk, return and maturity. The major types of institutional investors in Germany are insurance companies and investment funds. We will examine the nature of their businesses, their size and role in the financial sector, the size and the composition of the assets under their management, aspects of financ ial regulation, and features of their asset-liability-management.
This paper proposes a non-standard way to combine lazy functional languages with I/O. In order to demonstrate the usefulness of the approach, a tiny lazy functional core language FUNDIO , which is also a call-by-need lambda calculus, is investigated. The syntax of FUNDIO has case, letrec, constructors and an IO-interface: its operational semantics is described by small-step reductions. A contextual approximation and equivalence depending on the input-output behavior of normal order reduction sequences is defined and a context lemma is proved. This enables to study a semantics of FUNDIO and its semantic properties. The paper demonstrates that the technique of complete reduction diagrams enables to show a considerable set of program transformations to be correct. Several optimizations of evaluation are given, including strictness optimizations and an abstract machine, and shown to be correct w.r.t. contextual equivalence. Correctness of strictness optimizations also justifies correctness of parallel evaluation. Thus this calculus has a potential to integrate non-strict functional programming with a non-deterministic approach to input-output and also to provide a useful semantics for this combination. It is argued that monadic IO and unsafePerformIO can be combined in Haskell, and that the result is reliable, if all reductions and transformations are correct w.r.t. to the FUNDIO-semantics. Of course, we do not address the typing problems the are involved in the usage of Haskell s unsafePerformIO. The semantics can also be used as a novel semantics for strict functional languages with IO, where the sequence of IOs is not fixed.
Bei der Bestimmung von Eingriffsbefugnissen der BaFin jenseits der vom Gesetz vorgesehenen besonderen Kompetenzen ist Zurückhaltung geboten: Die Auffangermächtigung nach § 4 Abs. 1 Satz 3 WpÜG ist keine Allzweckwaffe nach Art der polizeilichen Generalklausel, sondern soll lediglich die besonderen Ermittlungs- und Eingriffsbefugnisse der Behörde dort ergänzen, wo diese Befugnisse auch im Zusammenwirken mit anderen Rechtsfolgen von Pflichtverstößen nicht ausreichen, um die Regelungen des Gesetzes durchzusetzen und das Gesetz dieses Sanktionsdefizit auch nicht bewusst in Kauf nimmt. In den praktisch wichtigen Fällen der Erzwingung von Pflichtangeboten, der Änderung von Angeboten nach ihrer Veröffentlichung und des Einschreitens gegen unzulässige Abwehrmaßnahmen ist danach für den Rückgriff auf § 4 Abs. 1 Satz 3 WpÜG kaum Raum. Beim Rechtsschutz Dritter gegenüber der BaFin verfolgt das Gesetz eine mittlere Linie: Amtshaftungsansprüche wegen fehlerhafter Aufsicht und Ansprüche auf Einschreiten der Behörde sind durch die Öffentlichkeitsklausel des § 4 Abs. 2 WpÜG in verfassungsrechtlich unbedenklicher Weise ausgeschlossen. Dagegen besagt § 4 Abs. 2 WpÜG nichts über die Schutzrichtung der Regelungen über das Angebotsverfahren. Die Vorschrift steht dementsprechend nicht einer Anfechtung begünstigender Verfügungen durch Dritte entgegen, soweit das Gesetz auch den Schutz ihrer Interessen bezweckt. Daher sind insbesondere Aktionäre der Zielgesellschaft befugt, mit Widerspruch und Beschwerde gegen Befreiungen nach §§ 36 und 37 WpÜG vorzugehen, die in ihr Recht auf Abgabe eines Pflichtangebotes eingreifen.
The use of GARCH models with stable Paretian innovations in financial modeling has been recently suggested in the literature. This class of processes is attractive because it allows for conditional skewness and leptokurtosis of financial returns without ruling out normality. This contribution illustrates their usefulness in predicting the downside risk of financial assets in the context of modeling foreign exchange-rates and demonstrates their superiority over use of normal or Student´s t GARCH models.
Efficient systems for the securities transaction industry : a framework for the European Union
(2003)
This paper provides a framework for the securities transaction industry in the EU to understand the functions performed, the institutions involved and the parameters concerned that shape market and ownership structure. Of particular interest are microeconomic incentives of the industry players that can be in contradiction to social welfare. We evaluate the three functions and the strategic parameters - the boundary decision, the communication standard employed and the governance implemented - along the lines of three efficiency concepts. By structuring the main factors that influence these concepts and by describing the underlying trade-offs among them, we provide insight into a highly complex industry. Applying our framework, the paper describes and analyzes three consistent systems for the securities transaction industry. We point out that one of the systems, denoted as 'contestable monopolies', demonstrates a superior overall efficiency while it might be the most sensitive in terms of configuration accuracy and thus difficult to achieve and sustain.
We use consumer price data for 81 European cities (in Germany, Austria, Finland, Italy, Spain, Portugal and Switzerland) to study the impact of the introduction of the euro on goods market integration. Employing both aggregated and disaggregated consumer price index (CPI) data we confirm previous results which showed that the distance between European cities explains a significant amount of the variation in the prices of similar goods in different locations. We also find that the variation of relative prices is much higher for two cities located in different countries than for two equidistant cities in the same country. Under the EMU, the elimination of nominal exchange rate volatility has largely reduced these border effects, but distance and border still matter for intra-European relative price volatility.
We use consumer price data for 205 cities/regions in 21 countries to study PPP deviations before, during and after the major currency crises of the 1990s. We combine data from industrialized nations in North America (Unites States, Canada and Mexico), Europe (Germany, Italy, Spain and Portugal), Asia (Japan and South Korea), and Oceania (Australia and New Zealand) with corresponding data from emerging market economies in South America (Argentina, Bolivia, Brazil, Columbia) and Asia (India, Indonesia, Malaysia, Philippines, Taiwan, Thailand). By doing so, we confirm previous results that both distance and border explain a significant amount of relative price variation across different locations. We also find that currency attacks had major disintegration effects by considerably increasing these border effects and by raising within-country relative price dispersion in emerging market economies. These effects are found to be quite persistent since relative price volatility across emerging markets today is still significantly larger than a decade ago.
Over-allotment arrangements are nowadays part of almost any initial public offering. The underwriting banks borrow stocks from the previous shareholders to issue more than the initially announced number of shares. This is combined with the option to cover this short position at the issue price. We present empirical evidence on the value of these arrangements to the underwriters of initial public offerings on the Neuer Markt. The over-allotment arrangement is regarded as a portfolio of a long call option and a short position in a forward contract on the stock, which is different from other approaches presented in the literature. Given the economically substantial values for these option-like claims we try to identify benefits to previous shareholders or new investors when the company is using this instrument in the process of going public. Although we carefully control for potential endogeneity problems, we find virtually no evidence for a reduction in underpricing for firms using over-allotment arrangements. Furthermore, we do not find evidence for more pronounced price stabilization activities or better aftermarket performance for firms granting an over-allotment arrangement to the underwriting banks.
Regulierung von Hedge Fonds in Deutschland : Bestandsaufnahme, praktische Erkenntnisse und Ausblick
(2003)
Die alternative Kapitalanlage über Hedge Fonds gewinnt in Deutschland zunehmend an Bedeutung. In der jüngsten Vergangenheit wurde dieses Thema daher auch in der rechtswissenschaftlichen Literatur aufgegriffen, was zu mehr Transparenz geführt hat. Allerdings ist das deutsche Investmentrecht und insbesondere der Spezialbereich "Hedge Fonds" nach wie vor eine Praktikerdomäne. Deshalb soll im Folgenden zunächst eine Bestandaufnahme erfolgen. Darüber hinaus werden aktuelle Entwicklungen beschrieben. Dabei lassen die Verfasser ihre praktischen Erkenntnisse einfließen. Vor diesem Hintergrund wird anschließend die vom Gesetzgeber für Anfang 2004 geplante Hedge Fonds-Regulierung gewürdigt.
Increasingly, alternative investments via hedge funds are gaining importance in Germany. Just recently, this subject was taken up in the legal literature, too; this resulted in a higher product transparency. However, German investment law and, particularly, the special division "hedge funds" is still a field dominated by practitioners. First, the present situation shall be outlined. In addition, a description of the current development is given, in which the practical knowledge of the author is included. Finally, the hedge fund regulation intended by the legislator at the beginning of the year 2004 is legally evaluated against this background.
Spacially dispersed transnational professional communities can be perceived of as cultural formations living in a global frame of reference, transgressing existing political and cultural boundaries. In their capacity as members of local technical and knowledgebased elites, they take part in circulating and connecting cultural meanings that are both locally produced, and continuously re-working non- local flows. I argue that those elites can be described as actors at cultural interfaces, taking part in shaping and mediating social change. The aim is twofold: one, to point to mutually opposed tendencies, and ambivalences in the framework of a „culture of change“, and two, to look into the question how such situations and groups can be methodologically approached.
This paper analyses the long-term effects of improved small-scale lending, often provided by microfinance institutions set up with the support of development aid. The analysis shows that some common assumptions about microfinance are not true at all: First, it shows that the impact on income will accrue not to the microenterprises themselves, but rather to the consumers of their products. Second, microfinance will have a significant positive effect on the wage levels of employees in the informal sector. Third, microfinance will cause high growth rates in the informal production sector, whereas the trade sector will either contract or at best grow very little.
The theoretical derivation of credit market segmentation as the result of a free market process
(2003)
Information asymmetries make it difficult for banks to assess accurately whether specific entrepreneurs are able and/or willing to repay their loans. This leads to implicit interest rate ceilings, i.e. banks "refuse" to increase their interest rates beyond this ceiling as this would lower their net returns. Although the maximum interest rate increases as the size of enterprises decreases, such ceilings nonetheless constrain the banks’ ability to set interest rates at a level that would enable them to cover costs. If transaction costs are high, the total costs associated with granting small and medium-sized loans will exceed the maximum average return which the banks can earn by issuing such loans. For this reason, banks do not lend to small and medium-sized enterprises, and, as a consequence, these businesses have no access to formal sector loans. Because micro and small enterprises have a very high RoI, it is worthwhile for them to rely on expensive informal loans to finance their operations, at least until they reach a certain size. Once they have reached this size, however, it does not make economic sense for them to continue taking out informal credits, and thus they face a growth constraint imposed by the credit market. Medium-sized enterprises earn a lower RoI than small ones, which is why borrowing in the informal credit market is not a worthwhile option for them. Moreover, they do not have access to credit from formal financial institutions, and are thus excluded from obtaining any kind of financing in either of the two credit markets. As the result of free, unregulated market forces we get a stable equilibrium in which the credit market is segmented into an informal (small loan) segment, a formal (large loan) segment and, in between, a "non-market" (medium loan) segment.
Despite the apparent stability of the wage bargaining institutions in West Germany, aggregate union membership has been declining dramatically since the early 90's. However, aggregate gross membership numbers do not distinguish by employment status and it is impossible to disaggregate these sufficiently. This paper uses four waves of the German Socioeconomic Panel in 1985, 1989, 1993, and 1998 to perform a panel analysis of net union membership among employees. We estimate a correlated random effects probit model suggested in Chamberlain (1984) to take proper account of individual specfic effects. Our results suggest that at the individual level the propensity to be a union member has not changed considerably over time. Thus, the aggregate decline in membership is due to composition effects. We also use the estimates to predict net union density at the industry level based on the IAB employment subsample for the time period 1985 to 1997. JEL - Klassifikation: J5
Financial markets are to a very large extent influenced by the advent of information. Such disclosures, however, do not only contain information about fundamentals underlying the markets, but they also serve as a focal point for the beliefs of market participants. This dual role of information gains further importance for explaining the development of asset valuations when taking into account that information may be perceived individually (private information), or may be commonly shared by all traders (public information). This study investigates into the recently developed theoretical structures explaining the operating mechanism of the two types of information and emphasizes the empirical testability and differentiation between the role of private and public information. Concluding from a survey of experimental studies and own econometric analyses, it is argued that most often public information dominates private information. This finding justifies central bankers´ unease when disseminating news to the markets and argues against the recent trend of demanding full transparency both for financial institutions and financial markets themselves.
This paper analyses the role of collateral in loan contracting when companies are financed by multiple bank lenders and relationship lending can be present. We conjecture and empirically validate that relationship lenders, who enjoy an informational advantage over arm’s-length banks, are more senior to strengthen their bargaining power in future renegotiation if borrower’s face financial distress. This deters costly conflicts between lenders and fosters workout decisions by the best informed party. Consistent with our conjecture, we find that relationship lender in general have a higher probability to be collateralized, and a higher degree of collateralization (i.e. seniority). Furthermore, we show that seniority and the status of relationship lending increases the likelihood that a bank invests in a risky workout of distressed borrowers. Both findings support the view that collateral is a strategic instrument intended to influence the bargaining position of banks. Our result further suggest that seniority and relationship lending are complementary to each other. JEL Classification: G21
Die vorliegende Arbeit soll sich mit dem „Zusammenziehen von Wörtern“ beschäftigen, das als typisch für die „Pottsprache“ […] angesehen wird. Dieses Zusammenziehen soll innerhalb der Klitisierungsforschung anhand zweier Fälle untersucht werden. Zum einen sollen reduzierte Formen der Pronomina und zum anderen reduzierte Artikelformen, nämlich die des bestimmten und des unbestimmten Artikels, als Untersuchungsgegenstand dienen. Dieses soll auf einer empirischen Basis, dass heißt auf der Basis von erhobenen und analysierten Sprachdaten, geschehen. Der erste Schritt soll dabei eine Darstellung der hier behandelten Sprachvarietät sein. […] Der zweite Schritt besteht in einer Darstellung der Theorie der Klitisierung […] Nachdem der Hintergrund dieser Arbeit dargestellt worden ist, folgt die eigentliche Analyse. Zunächst wird die Klitisierung von Pronomina untersucht […], dann die von Artikelformen […]. Beide Phänomene werden nacheinander auf ihre Eigenschaften hin untersucht, um dann zum Schluss zu einer Hypothese aus der bisherigen Forschung, nämlich die der flektierten Präpositionen, Stellung zu beziehen […]. Abschließend soll versucht werden die Ergebnisse dieser Arbeit in den Forschungsstand bei der Erforschung von Klitisierung auf der einen Seite und der Varietät Ruhrdeutsch auf der anderen Seite einzuordnen […].
It is known that deterministic finite automata (DFAs) can be algorithmically minimized, i.e., a DFA M can be converted to an equivalent DFA M' which has a minimal number of states. The minimization can be done efficiently [6]. On the other hand, it is known that unambiguous finite automata (UFAs) and nondeterministic finite automata (NFAs) can be algorithmically minimized too, but their minimization problems turn out to be NP-complete and PSPACE-complete [8]. In this paper, the time complexity of the minimization problem for two restricted types of finite automata is investigated. These automata are nearly deterministic, since they only allow a small amount of non determinism to be used. On the one hand, NFAs with a fixed finite branching are studied, i.e., the number of nondeterministic moves within every accepting computation is bounded by a fixed finite number. On the other hand, finite automata are investigated which are essentially deterministic except that there is a fixed number of different initial states which can be chosen nondeterministically. The main result is that the minimization problems for these models are computationally hard, namely NP-complete. Hence, even the slightest extension of the deterministic model towards a nondeterministic one, e.g., allowing at most one nondeterministic move in every accepting computation or allowing two initial states instead of one, results in computationally intractable minimization problems.
Zur Versprachlichung des Raums in Bildergeschichten deutschsprachiger Vor- und Grundschulkinder
(2002)
Gegenstand der vorliegenden Arbeit ist die Versprachlichung des Raums in Bildergeschichten deutschsprachiger Vor- und Grundschulkinder. Methodisch fügt sich die Untersuchung in Arbeiten zur Entwicklung der narrativen Kompetenz des Kindes anhand von Bildergeschichten ein, wie sie in neuerer Zeit […] durchgeführt wurden (s. vor allem Berman & Slobin 1994). Hinsichtlich der allgemein-sprachwissenschaftlichen Analyse der Versprachlichung des Raums ist die Arbeit vor allem den typologischen Studien von L. Talmy (1985, 1991) verpflichtet. […] Ziel der vorliegenden Arbeit ist es, die Rolle der Versprachlichung räumlicher Beziehungen unter zwei Aspekten zu untersuchen: hinsichtlich der Erstellung kohärenten narrativen Diskurses und hinsichtlich der sprachlichen Mittel, mittels derer die Kinder auf statische und dynamische räumliche Beziehungen referieren. Entsprechend der Dreiteilung der Ich-Jetzt-Hier-Origo stellen räumliche Beziehungen neben der Referenz auf Personen und zeitliche Beziehungen einen der drei Bereiche dar, in denen sich textuelle Kohärenz manifestiert. Bei der Versprachlichung des Raums geht es einerseits um Einführung, Beibehaltung und Verschiebung narrativer Orte und andererseits um statische räumliche Befindlichkeiten gegenüber dynamischen räumlichen Ereignissen. […] Die Arbeit gliedert sich in einen theoretischen und einen empirischen Hauptteil.
Vortrag in Linz im KunstRaum Goethestrasse am 25.09.2002 im Rahmen der Reihe ESTABLISH CULTURAL WORKER - Ist die KulturArbeit (oder) Kunst?: Zuerst möchte ich kurz zu dem Moriana Projekt etwas sagen. Es wurde in 7 Städten durchgeführt, und war ein europäisches Forschungsprojekt von einem italienischen Forschungsinstitut. Es ging um die Situation von Kleinstselbstständigen, FreiberuflerInnen etc. Dies mit einem erneuerten Ansatz dessen, was früher einmal Arbeitermituntersuchung hiess, nämlich militante Untersuchung. Das heisst, die Leute die in den Verhältnissen stecken, analysieren selbst ihre Arbeitssituation, versuchen selbst ihre Bedürfnisse zu beschreiben, versuchen selbst diesen Arbeitsprozess zu beschreiben, und werden, durch einen Intervention des/der ForscherIn, versucht in eine bestimmte Richtung zu drängen. Nämlich in die Richtung, für ihre Interessen zumindest zu einer Selbstformulierung zu kommen, wenn nicht gar zu einer Selbstorganisierung. Letzteres hat bei dem Projekt nicht geklappt, oder nur zu ganz kleinen Teilen. ...
In nur wenigen Jahren wird die Euopäische Union um eine Gruppe osteuropäischer Staaten erweitert werden. Diese Erweiterung birgt Chancen und Risiken. Die Chancen liegen unter anderem in der Erweiterung der Märkte und gegenseitigen Handelsbeziehungen. Voraussetzung hierfür ist allerdings gegenseitiges Verständnis im doppelten Sinn dieses Wortes. Wenn die Menschen sich nicht verstehen, werden auch neue Möglichkeiten nicht genutzt werden können, wenn die Wirtschaft nicht die richtige Sprache findet, kann sie nichts verkaufen. Für alle wirtschaftlichen, kulturellen und gesellschaftlichen Bereiche ist eine funktionierende verbale Kommunikation unerläßlich. Wie viel mehr gilt dies für grenzüberschreitende Beziehungen. Die Erweiterung der EU wird nur dann in eine Integration der neuen Kandidaten münden können, wenn die Verständigung zwischen allen Beteiligten gesichert ist. In dem vorliegenden Bändchen weisen die Autoren nach, dass nur durch Sprachkultur und eine einschlägige Forschung, die auch die kulturspezifischen Konnationen mit berücksichtigt, eine interkulturelle Sprachkompetenz erworben werden kann. In der Sprachenvielfalt eines vereinten Europa wird eine solche Kompetenz mehr denn je gefragt sein. Welche Wege uns diesem Ziel näher bringen und welche Möglichkeiten die deutsche Sprache hat, der wachsenden Sprachkonkurrenz international zu begegnen, das ist die Fragestellung der hier publizierten Studien, die dazu eine Fülle von Vorschlägen, Empfehlungen und Anregungen beisteuern. Die Arbeiten sind Ergebnisse des forost-Projektes "Sprachkultur und Sprachkultivierung in Osteuropa – ein paradigmatischer Vergleich", das sich innerhalb der Gruppe III des Forschungsverbundes "Nationale Identität, ethnischer Pluralismus und internationale Beziehungen" dieser Thematik gewidmet hat.
Im Bericht werden vorgestellt die: • Eigenschaften von Mooren und Torfen wie Fossilinhalt, Nähr-/Schadstoffhaushalt und Wasserhaushalt, • moorgeologische Inventur (Moorkataster) des Landes Baden-Württemberg und • Bodenfunktionen von Moor-/Torfstandorten im Sinne des § 2 (2) des Bundesbodenschutzgesetzes (BBodSchG) vom 17. März 1998. Moore/Torfe sind Landschaftselemente, die im Naturhaushalt Funktionen erfüllen und für die Nutzung durch Menschen der Raumplanung unterworfen sein können bzw. sind. Der folgende Text stellt den in die Raumplanung eingebundenen Personen und Organisationen vor: • Die Eigenschaften von Mooren und Torfen, • die Quelle verfügbarer, raumbezogener Daten (Moorkataster), • die an Planungen zu Beteiligenden, • die Quellen zu Informationen zu Moor und Torf, • das Auffinden eventuell notwendiger Gutachter und • grundsätzliche Hinweise zur Bewertung von Mooren/Torfen für Abwägungsprozesse. Der Text wurde veranlasst durch die digitale Übernahme des Moorkatasters in den RIPS-Pool der Landesanstalt für Umweltschutz in Teilen seit 2000 und vollständig ab 2003.
Die Bilder der Terroranschläge des 11. September in den Medien erinnerten viele Menschen an Katastrophenfilme aus Hollywood. Michael Staiger geht davon aus, dass die Bildsprache solcher Filme auch unsere Wahrnehmungsweise des realen Terrors beeinflusst. Er stellt eine zunehmende Verflechtung der Ästhetik des Hollywood-Kinos mit der Medienberichterstattung realer Ereignisse fest. "Die Inszenierung von Fernsehnachrichten verweist inzwischen ebenso auf fiktionale Bildwelten, wie sich die Spielfilmästhetik seit Jahren der Machart von Fernsehbildern bedient." Am Beispiel des Thrillers "Ausnahmezustand" (1998) analysiert Michael Staiger die Inszenierung des Terrors in Hollywood-Filmen und zeigt damit eine medienpädagogische Umsetzungsmöglichkeit des Themas auf.
This paper examines the political-economy and cultural dynamics and discourses underlying the emergence of the Palestinian Hamas and the Algerian Islamic Salvation Front. Both movements emerged in the late 1980s as responses to continuing (neo) colonial conditions in their countries. I explore to what extent the various processes commonly referred to as “globalization,” both the world-wide economic transformations epitomized by post-fordism on the macro/system level and neo-liberal structural adjustment programs within countries, and—perhaps more important—its cultural dynamics contributed to the rise and power of both movements. I examine the socio-economic situation in Algeria and Palestine-Israel during the 1980s and link it to the politics developments in both countries. Next I review the events behind the founding of both movements and the main components of their ideologies and strategies. Finally I explore their arguments to determine whether the political-economic or cultural pressures unleashed by globalization were the determining factor in their emergence and ideological development. I conclude by comparing the two case studies to determine if there are common threads that can serve as the basis for a region-wide investigation of the role of globalization in the emergence and/or rise to social hegemony of Islamist movements in other MENA countries.
