Since the end of the British Empire, which had provided white Australians with points of view, attitudes and stereotypes of the world - including perceptions of their own role in it -, rediscovering an international identity has been an Australian quest. Many turned to European roots; others to the Aboriginal landscape; Blanche d"Alpuget and Christopher J. Koch are two who have ventured into Asia for the culturally and spiritually regenerative materials necessary to redefine Australia in the post-colonial world. They have taken Eastern concepts of "self", and "soul" and forged them with the Australian obsession of fear and desire of contact with the "other" in a looking-glass of hybrid, Austral-Asian myth to reveal the true soul of Australian identity. Along with a brief historical and literary background to the triangular relationship between white Australia, Asia, and the West, this study- goal is to identify some of the Southeast Asian symbols, myths and literary structures which Koch and d"Alpuget integrate into the Western tradition. Central elements include: dichotomies as of personality, righteousness, and virtue; the "Otherworld", where one may approach enlightenment, but at the risk of falling into self-delusion; archetypes of the Hindu divine feminine; Eastern roots of Koch- themes of the "double man"; concepts of the forces of "light" and "dark"; the semiotics of time and meaning; and the central Eastern metaphor of the mirror by which Australia creates interdependent images of itself and of Asia.
Ausgehend davon, daß die nachweislich prominente Berichterstattung über bezahltes Dating sich nicht auf einen hohen Nachrichtenwert zurückführen läßt, sondern auf verkaufstechnische Faktoren und vor allem auf das "kulturelle Potential" des Themas Jugend, untersucht die folgende Arbeit, welche Normen und Werte in der Darstellung des Phänomens propagiert wurden, und ob sich in der Darstellung Muster erkennen lassen.
Until today the effects of many chlorinated hydrocarbons (e.g. DDT, PCBs) against the specific organisms are still a subject of controversial discussions. It was also the case for potential endocrine effects to influence the spermatogenesis correlated with possible changes of the population's vitality. To clear this situation, three questions could be at the centre of attention: 1) Do the chemicals cause a special harmful effect on the male reproductive tract? 2) Could some particular chemical mixtures act to bind and activate the human estrogen receptor (hER)? 3) Are the life stages of an organism specially sensitive to the effects of chemicals and therefore be established as Screening-Test-System? the connected effects of DDT and Arochlor 1254 as single substance and in 1:1 mixture according to their estrogenic effectiveness on zebrafish (Brachydanio rerio) were therefore investigated. the concentrations of the pesticides and their mixture ranged between 0.05-µg/l and 500-µg/l and separated by a factor of 10. It was turned out that the test concentrations of 500-µg/l were too toxic to zebrafish in all the cases. The experiment was followed up with four concentrations of DDT, A54 as well as their 1:1 mixture anew each separated by a factor of 10 and ranging between 0.05-µg/l and 50-µg/l. The bioaccumulation test within 8 days showed that the zebrafish accumulated the chemicals, but no equilibrum was reached and the concentration 0.05-µg/l was established as No Observed Effect Concentration (NOEC). Putting up on these analyses, the investigation of the life cycle (LC) starting with fertilized eggs demonstrated a reduction in the rate of hatchability, reproduction and length of fish emerged. These reductions involved the duration of the life cycle stages (LCS) which consequently lasted longer than expected. Exposure time and level of the tested chemicals accelerated the occurrence of these effects which were more significant when the chemical mixtures were used too. To establish whether the parameter assessed were correlated to the male reproductive tract, the quality, quantity and life span of sperm were assessed using the methods of Leong (1988) and Shapiro et al (1994). The sperm degeneration observed, led us to investigate the spermatogenesis and the ultrastructure of the testes. This last experiment showed a significant reduction of the late stage of spermatogenesis and the heterophagic vacuoles which play an important role in the spermatid maturation. It could therefore be concluded that, DDT and A54 could act synergically and cause disorders of the male reproductive tract of male zebrafish and influence also their growth.
Die Natur hat sich gewandelt. Dieser Wandel, der wichtige Fragen bezüglich Wahrnehmung, Darstellung, Neuschöpfung und Übermittlung der Natur mit einschließt, wird auch von künstlerischer Seite reflektiert. Tatsächlich ist in den vergangenen Jahren erneut ein wachsendes Interesse seitens der Künstler am Thema Natur abzulesen. Dieser vorläufige Höhepunkt des Trends ist vor allem auf das Ende der 1990er Jahre zu datieren. Zu dieser Zeit setzten sich auch verstärkt Ausstellungen und Publikationen mit diesem Themenkomplex auseinander. Mit unterschiedlichen Schwerpunkten und Vorstellungen entwickelten Künstler darin eigene, ganz verschieden künstlerische Konzepte, analysieren, erforschen und kritisieren die Gesellschaft, die Umwelt und die Natur des Menschen. Ein Trend, der bis heute anhält. Die vorliegende Arbeit möchte anhand ausgesuchter Künstler und Arbeiten genauer untersuchen, wie Künstler gegenwärtig mit der Natur umgehen, wie sie das Verhältnis zur Natur definieren und auf welche Traditionen sie gegebenenfalls zurückgreifen. Alle vorgestellten künstlerischen Positionen werden thematisch oder hinsichtlich konkret fassbarer Probleme gegliedert und vorgestellt. Exkurse über historische Entwicklungen oder thematische Schwerpunkte begleiten die Übersicht. Ziel der vielfältigen Blickpunkte ist es, im Vergleich mit den einzelnen Positionen neue Standorte zwischen Natur und Kultur vorzustellen, neu zu definieren oder erst zu entwickeln.
Die Zahl der (potenziellen) Kunden der Dienstleistungsbranche Tourismus und deren Ver-teilung im Raum wird durch eine Vielzahl von Ursachen (Bedürfnis- und Verhaltens-dimension der Tourismusforschung) bestimmt. Das sind z. B. auch Beweggründe, Bedürf-nisse, Motive oder auch Motivkomplexe. Die Kenntnis dieser Bedürfnisse und Verhaltens-weisen von Reisenden und deren Anforderungen an die offerierte Leistung sind dabei eine zentrale Voraussetzung für eine zielgruppengerechte Marktbearbeitung. Ein wichtiger Bestandteil dieser notwendigen Zielgruppenorientierung ist die Marktsegmentierung, deren Aufgabe darin besteht, den relevanten Markt in intern möglichst homogene und untereinander heterogene Teilmärkte aufzuteilen. Eine Segmentierung des Tourismusmarktes erfolgte bislang vornehmlich anhand verschiedener Einschränkungen. Aufgrund der geringen Aus-sagekraft der bisherigen Ansätze für das durch umfangreiche Motivkomplexe geprägte Reise-verhalten der Nachfrager erweist sich allerdings eine zielgruppenspezifische Markt-bearbeitung auf Basis derartiger Lösungen als nur bedingt möglich. Dieser Kritik Rechnung tragend wurde ein ganzheitlicher Segmentierungsansatz entwickelt, der an möglichst zahl-reichen Ausprägungsformen des Reiseverhaltens ansetzt, alle vier klassischen Markt-erfassungsansätze verbindet und damit Handlungsempfehlungen für eine breit angelegte zielgruppenspezifische Marktbearbeitung aufzeigt. Eine weitere Neuerung bezieht sich auf die Anwendung einer multivariaten Baumanalyse, um Zielgruppen im Tourismus zu differen-zieren. Dieses Analyseverfahren erlaubt die gemeinsame Analyse mehrerer Variablen und von Variablen jedes Skalenniveaus. Dazu wurden mehr als 6.000 mündlich geführte Interviews, die mittels einer Zielgebiets-befragung 1997-1999 in Rheinland-Pfalz erhoben wurden, ausgewertet. Das Hauptaugenmerk lag dabei auf der multivariaten Analyse mit Hilfe des sogenannten CHAID-Algorithmus. Es handelt sich dabei um eine Art Baumdiagramm, welches erstmalig als Instrument der touristischen Zielgruppenplanung mittels Segmentbildung und Profilerstellung eingesetzt und daher als Alternative zu Cluster- und Diskriminanzanalyse charakterisiert wird. Dabei kann eine Vielzahl verschiedenartiger Typisierungen untersucht werden, wie etwa die Typisierung der Reisenden mit hohem Reisestellenwert (z. B. der Haupturlauber), mit ausgeprägter Besuchshäufigkeit bzw. Zielgebietserfahrung, mit hoher Rückkehrbereitschaft, außergewöhnlicher Zufriedenheit oder des kaufkräftigen Urlaubers. Abschließend erfolgt die Beurteilung der Ergebnisse bezüglich der praktischen Bedeutung für das Rheinland-Pfalz-Marketing.
The importance of the hotel sector as part of the cultural environment has not been recognised yet, partly because of a missing awareness that hotels could actually be regarded as a national treasure. The hotel business is not only a service provider for tourism - supplying different options for overnight stays - but also representative of social and built environment. It works as a meeting place and communication point; it reflects former and current culture of living as well as buildings. Within a rapidly changing world there is an increasing requirement of protecting measures for ever more aspects of the environment as e.g. for national heritage and nature conversation. So far nobody thought that hotels and inns might qualify for this category and any initiatives taken so far were generally based on private effort. A public awareness does not exist, partly because the difference between culturally worthy objects/ensembles is solely depending on individual measures of value. A classification in categories, which strengthens awareness for the hotel environment and also allows an affiliation of giving cover, is missing. This work is dedicated to exactly that shortage. In the beginning it proves that hotels/inns are worthy being integrated into protective measures. They are important representatives of the built and social culture including the living culture where one lives history. The main part of the work concentrates on a two-part systematisation ï‚· An areal allocation seems essential to rate where exactly in a town protective measures are needed. In order to do so examples for the so called "town protection zones" (Stadtschutzzone) by JÄTZOLD are used. ï‚· Following the idea of the town protection zones an introduction of a historical categorisation will be introduced, which allows allocating objects and ensembles into the different eras. The history of hotels and concise examples will show the differences " relics of early tourism, time of hostels and inns, health resorts and grand hotels, recent developments as well as stylish hotels. Subsequent to this categorisation additional conceptual suggestions to be used in praxis are made, taking into account the decision-makers that should be involved. It results in a multidisciplinary approach, which integrates heritage, town planning, bearers of cultural awareness, policy makers, etc. Negative and positive examples are deployed to force the urgency of a sensible exposure with the treasure "hotel". To force the necessity a comparison between Germany and Great Britain is used where applicable. The author believes the cultural awareness in Great Britain, which also integrates the protection of the hotel sector, is much higher and better than in Germany.
This doctoral dissertation examines two authors of German descent who are representatives for the development of Canadian literature and its regional focus on the prairies: Frederick Philip Grove (1879-1948) and Robert Kroetsch (*1927). Kroetsch, in his essays and talks, has repeatedly referred to Grove as one of his "literary ancestors". Although there exist monographs and numerous articles on both authors, the present study is the first-ever comparative approach. This study's main access is provided by the motif of disguise and masquerade, which plays a central role in the authors' works. Even if critics have looked at the traditional motif (cf. Homer's Odyssey, or many Renaissance plays) in Kroetsch's writing sporadically, and have used it to examine Grove's biography, no approach has attempted a larger contextualization within/among both writers' oeuvres. According to Lloyd Davis, however, the motif can be seen as "representing the cultural dialogism, rather than any particular thesis, of selfhood" (Davis 16). Hence, it helps interrogate a topic that within Canada - the former colony and current multicultural immigrant society - had and has a specific relevance. As an analytical tool, the motif allows for highlighting both the similarities and the differences between the œuvres of Grove and Kroetsch as key-figures of a (post)colonial literature of Western Canada on the one hand, and for general questions pertaining to the characterisation of figures, the definition of narrative positions and even of genres on the other hand. Following the preface, two theoretical chapters outline conceptions of identity and their deducible forms and functions of disguise and masquerade, including a discussion of John Richardson's Wacousta (1832), which is the first Canadian example for the motif's constitutive use. The second major section sketches, in two separate chapters, the poetics and mentalities (Mentalitätsgeschichte) of each writer within the context of their complete works by looking at biographical data as well as the critics' assessments. After immigrating into Manitoba in 1912, Grove soon became the first representative of a literary prairie-realism. Before, he had faked his suicide in 1909 and stripped off his 'original' identity as the German translator (e.g., Wilde, Wells, Flaubert) as well as modestly successful poet and novelist Felix Paul Greve to leave behind debts and a notorious lover and to reinvent himself in the New World. The protean role-plays of 'FPG' - decoded only 23 years after his death - are manifested in his creation of literary characters, in a "collectivity of identities" (Cavell 12) or number of metonymic personae that keep his critics busy to this date. Providing a different story, Kroetsch's family of German background immigrated into Canada in the mid-19th-century. Kroetsch has been thematizing his native province, Alberta, just as much as general national dispositions or questings in the course of his literary career spanning five decades now. His progressive and experimental writing has earned him, for instance, the label of "Mr Canadian Postmodern" by Linda Hutcheon (Canadian Postmodern 183). Particularly important among his specifically postmodern instruments is the principle of archaeology as derived from Foucault and employed as both metaphor and method; further methodological tools are Barthes' theories on reading/writing as an erotic act, Bakhtin's notion of (the) carnival(ization of literature) and a great sensibility for the myths as well as oral traditions of the North American Natives. If the third section analyzes two of FPG's novels to illustrate his transfer, or literal translation, from a German to a Canadian cultural context, the fourth section represents this study's core with three one-to-one comparisons of the two writers' central prose texts. In spite of all affinities between both authors, however, this section already indicates what section five further underlines: Kroetsch clearly transcends Grove's achievements (which ultimately reduce all his characters and texts to nothing but his own will- and wishful projections and identity-configurations); on the level of narrativity, genre and gender, Kroetsch not only goes far beyond parodying Grove, but proves to be an innovator whose mis-en-scène of the motif of disguise provides both more psychological depth and relevance for socio-historical contexts. This comparative study has been informed by research in the Special Archives and Collections at the University of Manitoba (Grove Papers) and at the University of Calgary (Kroetsch Papers), by related talks at Lund, Belfast and Winnipeg as well as by an occasional quotation from an interview I conducted with Robert Kroetsch as early as 1996.
Insbesondere im wissenschaftlichen Bereich ist es zur Selbstverständlichkeit geworden, zur Befriedigung eines Informationsbedürfnisses zunächst das World Wide Web (Web) zu benutzen. Der komplexe Aufbau des Webs und die dort herrschende Unordnung machen das Auffinden bestimmter Dokumente zu einem diffizilen Vorgang. Suchmaschinen und Web-Verzeichnisse unterstützen den Benutzer hierbei; ihre effektive Nutzung ist jedoch nicht einfach. Es ist daher hilfreich, Suchdienste zu entwickeln, welche Kontextwissen mitbringen. In der vorliegenden Arbeit wird das Verfahren der thematisch spezialisierten Suche präsentiert und anhand der Menge der persönlicher Home Pages von Informatikern exemplifiziert. Der Bibliographie-Server DBLP.uni-trier.de liefert u.a. zu über 4.000 Wissenschaftlern manuell gesammelte persönliche Home Pages. Durch verschiedene Analysen werden in dieser Menge häufig vorkommende, also relevante Eigenschaften ermittelt. Dies ist ein kreativer Prozess, in den sowohl Suchwissen -- Wissen über Techniken des Suchens im Web -- als auch Fachwissen -- Wissen über die Beschaffenheit persönlicher Home Pages -- einfließen. Nach der Überprüfung dieser Eigenschaften auf ihre Signifikanz in der Gesamtheit der Web-Dokumente ist ein thematisch spezialisiertes Wissen erschaffen worden. Zur Durchführung der Suche würde man idealerweise alle Web-Dokumente mit Hilfe des erarbeiteten Wissens und des Anfrageterms -- des vollständigen Namens eines Informatikers -- untersuchen. Da das Web aus mehreren Milliarden Dokumenten besteht, ist dies praktisch nicht durchführbar: Es ist notwendig, eine geeignete Vorauswahl zu treffen. Suchmaschinen haben Daten zu vielen Web-Dokumenten erfasst. Deshalb wird mit ihrer Hilfe unter Verwendung des Anfrageterms eine Vorauswahl getroffen. Um nun die Dokumente der Vorauswahlmenge gemäß der Anfrage zu bewerten wird das thematisch spezialisierte Wissen adäquat in einer Bewertungsfunktion repräsentiert, welche jedem Dokument einen Wert zuweist und somit eine Rangfolge erstellt. Das Design der Bewertungsfunktion ist eine schöpferische Tätigkeit: Die sachgerechte Gewichtung der verschiedenen Eigenschaften bestimmt maßgeblich das Gelingen des Verfahrens. Der vornehmlich in Java implementierte, vollautomatisierte Web-Dienst HomePageSearch (hpsearch.uni-trier.de) führt regelmäßig für über 100.000 Namen diesen Suchvorgang durch. Der Benutzer kann auf das in einer DB2-Datenbank gespeicherte Ergebnis zurückgreifen. Durch die periodische Neuberechnung des thematisch spezialisierten Wissens wird der Dynamik des Webs Rechnung getragen. Der modulare und stark parametrisierte Aufbau des Systems erleichtert die Portierung des Verfahrens auf andere Mengen von Web-Dokumenten. Nicht zuletzt aufgrund der starken Verlinkung mit DBLP und ResearchIndex wird HomePageSearch von vielen Wissenschaftlern intensiv genutzt.
In Ostafrika ist der Fußgängerverkehr die mit Abstand wichtigste Fortbewegungsart. Dies gilt für städtische und ländliche Gebiete! Tatsache ist aber, dass die Probleme der Fußgänger in der Planung nicht ausreichend berücksichtigt werden. Die Politiker richten ihre zentrale Aufmerksamkeit auf den motorisierten Individualverkehr und missachten somit die Bedürfnisse der Mehrheit der Bevölkerung. Diese Disparität kann im Zuge einer nachhaltigen Entwicklung reduziert werden. Der nicht-motorisierte sowie der öffentliche Verkehr müssen stärker gefördert werden, da der motorisierte Individualverkehr in Ostafrika auf lange Zeit der breiten Bevölkerungsschicht vorenthalten bleibt. Westliche Wohlstandsmodelle dürfen demnach nicht als Verkehrsvorbild dienen. Die Entwicklungszusammenarbeit ist aufgerufen, Projekte in den Bereichen des öffentlichen sowie des nicht-motorisierten Verkehrs gezielt zu fördern. Nur so kann eine Transportplanung erfolgen, die ökologisch nachhaltig, sozial gerecht, ökonomisch effizient, politisch regulierend und investitionsfördernd ist. Durch gezielte Maßnahmen könnte eine Trendwende erreicht werden. Die Chancen für ein Umdenken in Form angepasster Verkehrspolitik sind gegeben. Wenn Industrieländer mit gutem Beispiel vorangehen, werden sich die Entwicklungsländer diesem Trend nicht verschließen können.
Die Lateralitätsforschung hat bis dato eine Vielzahl an Hinweisen für einen linkshemisphärischen Leistungsvorteil für die Verarbeitung verbalen Materials und umgekehrt einen rechtshemisphärischen Vorteil für die Verarbeitung bildhaften Materials aufzeigen können. Doch fällt auf, daß kaum Studien existieren, in denen Verhaltensasymmetrien und Asymmetrien elektrophysiologischer Hirnaktivität in einer experimentellen Umgebung gemeinsam untersucht wurden. Viele wissenschaftliche Autoren schlossen einfach von funktionellen Verhaltensasymmetrien auf zugrunde liegende strukturelle Asymmetrien, ohne dabei auf ein allgemeingültiges Erklärungsmodell zur Vorhersage und Integration beider Asymmetriemaße zurückzugreifen. Die Experimente dieser Arbeit setzen das in der psychophysiologischen Wahrnehmungsforschung bereits etablierte visuelle Halbfeldparadigma (VHF-Paradigma) ein, den Probanden werden dabei unterschiedliche visuelle Stimuli lateralisiert auf einem Computermonitor dargeboten. In diesem Untersuchungsrahmen bearbeiten die Versuchspersonen in zwei unterschiedlichen Experimenten zum einen abstrakte verbale Stimuli und zum anderen emotionale bildhafte Stimuli. Die P300- Komponente findet in dieser Studie eine besondere Berücksichtigung. Zentral ist hierbei die Fragestellung, ob das EKP und i.e.S. die P300-Komponente überhaupt zur Erfassung und Interpretation von lateralisierten kognitiven Prozessen geeignet ist. Zusammengefasst läßt sich feststellen, obwohl in den durchgeführten Wahrnehmungsexperimenten deutliche funktionellen Asymmetrien auf der Verhaltensebene resultieren, kann auf der Ebene der phasischen elektrokortikalen Asymmetrien keinesfalls von Lateralitätseffekten gesprochen werden. Das Muster der reizspezifischen Hemisphärenasymmetrie vieler Verhaltensexperimente kann in den hier untersuchten elektrophysiologischen Parametern nicht ansatzweise nachvollzogen werden. Zwar können die funktionelle Asymmetrien in Trefferquoten und Reaktionszeiten zwar einen ersten Hinweis auf strukturelle Asymmetrien darstellen, doch kann aufgrund der vorliegenden Befundlage nicht ohne weiteres von der Verhaltensebene auf Asymmetrien der elektrophysiologischen Ebene geschlossen werden.
Selbstverletzende Verhaltensweisen und Autoaggressionen im Kontext Geistiger Behinderung sowie deren Fernwirkungen auf die Betreuungspersonen in Wohnheimen und Werkstätten gilt das Hauptinteresse vorliegender Arbeit. Ausgehend von der Darstellung der Spezifizität Geistiger Behinderung unterschiedlicher Schweregrade als Hintergrundvariablen der Genese und Aufrechterhaltung selbstverletzenden Verhaltens werden wesentliche theoretische Konzepte autoaggressiven Handelns diskutiert: medizinisch-physiologischen Befunde, psychodynamische Deutungsmuster, entwicklungspsychologische Annahmen, behaviorale Theorien, kognitive und systemische Ansätze. Im empirischen Teil der Arbeit, der sich auf eine Befragung von 136 Betreuungspersonen in Einrichtungen für Menschen mit Geistiger Behinderung stützt, lässt sich als wesentliche kognitive Deutung der Probanden die Provokationsannahme und das Vermeidungsmotiv bestätigen. Emotional stehen Ärger, Angst und Hilflosigkeit bei den Befragten im Vordergrund. Bestrafende Interventionen als entsprechende Handlungstendenz treten jedoch generell nicht vermehrt hervor, vielmehr scheint ein Interventionspluralismus auf, sich der weitgehend unabhängig von den angenommenen theoretischen Ursachen des selbstverletzenden Verhaltens entwickelt. Im Bezug auf Ausbrennen im Beruf und psychosomatische Belastungen ergeben sich keine direkten linearen Zusammenhänge zur Häufigkeit und zum Ausmaß der beobachteten Autoaggression. Auf der Grundlage einer pfadanalytischen Betrachtung, können lediglich ausgehend von der Vermeidungs- und Provokationsannahme über Ärgerreaktion und Bestrafungstendenz höhere Burnout-Werte und größere psychosomatische Belastung aufgezeigt werden. Im Schlussteil der Arbeit werden Ableitungen für die Praxis im Umgang mit selbstverletzendem Verhalten und Autoaggressionen dargestellt.
Soil and water conservation are cross-sectional assignments. The respective objectives of the individual interest groups cause conflicts of use and lead to different assessments of the soil's potential. Necessary decisions and the practical implementation of soil and water conservation measures require the use of data. These data, which are both spatial and temporal, characterise past, present and, in the case of predictions, also future environmental conditions. The multitude of relevant data necessitates the use of geographic information systems as an instrument for successful resource management. With the use of problem-oriented case studies, it was possible to show that an improved understanding of the system is necessary for both optimisation of the site-specific resource management within the framework of Precision Farming and for the assessment of local to regional conflicts of use with regard to land usage and soil and water conservation. By changing the method, sufficient respective measures regarding documentation, prevention and risk assessment were able to be introduced and implemented. With the objective of practical implementation of a sustainable resource management, the possibilities of short- to long-term initiation of self-organised systems through the networking of available (geo-)information as well as the respective interest groups involved in the conflict of use formed the focal point of this investigation. The creation of networks linking agriculture, water extractors and nature conservation promotes necessary synergies and emergences, due to increased communication. Not the conveyance of knowledge alone, but rather new forms of understanding cause the interest groups involved to change their behaviour, thus facilitating efficient resource management for the interests of soil and water conservation.

Hamanns knight tombs - Reception and transformation of a French type The thesis deals with an important group of tombs in the history of medieval art. The object of research is a particular group of figurative tombs for nobles from Marburg, Cappenberg, Bielefeld and Münstereifel. These tombs were brought to art historians attention by Richard Hamann in the year 1929. For the first time the research at hand considers the tombs as particularly instructive examples thus strengthening the basis for medieval studies. They also explain the function of memorial sculpture in medieval history. Interdisciplinary approaches of medieval studies are combined with critical valuation of historical research as well as fundamental research and the interpretation of sources. The up-to-date unpublished sources from the starting point for the specific research of the tombs. Biographic-genealogical aspects, actual church law, the historical-social context and the memorial purpose are the research areas from which the meaning of tombs was elaborated, as well as taking into consideration the medieval mentality about death and memory. The results of the research give a new valuation of these tombs, which form a key position regarding the spectrum of their statement for the development of art history and memorial history in the 14th century. The tombs reveal contact between artist and patron. They help to find out more about social circumstances intertwined with medieval art comissions. These memorials prove the existence of artistic grave specialists in the western German region of the 14th century, who were recommendet in turn by the closely related noble familiy. On a social-cultural level these memorials show the importance of royal French art as a distinctive model further more expressing the need for oneself to express social status by the means of art. These memorials are closely related to certain people. They are crucial to the research of medieval memorial sculpture. The memorial from Cappenberg is a paradigm for the shift from a cult ideology to a pure economic ideology thus showing proof of patroned memorials. Whereas the tombs in Marburg, Bielefeld and Münstereifel are keyworks showing the relevance of spontaneous and private memorial of the dead.
Today, usage of complex circuit designs in computers, in multimedia applications and communication devices is widespread and still increasing. At the same time, due to Moore's Law we do not expect to see an end in the growth of the complexity of digital circuits. The decreasing ability of common validation techniques -- like simulation -- to assure correctness of a circuit design enlarges the need for formal verification techniques. Formal verification delivers a mathematical proof that a given implementation of a design fulfills its specification. One of the basic and during the last years widely used data structure in formal verification are the so called Ordered Binary Decision Diagrams (OBDDs) introduced by R. Bryant in 1986. The topic of this thesis is integration of structural high-level information in the OBDD-based formal verification of sequential systems. This work consist of three major parts, covering different layers of formal verification applications: At the application layer, an assertion checking methodology, integrated in the verification flow of the high-level design and verification tool Protocol Compiler is presented. At the algorithmic layer, new approaches for partitioning of transition relations of complex finite state machines, that significantly improve the performance of OBDD-based sequential verification are introduced. Finally, at the data structure level, dynamic variable reordering techniques that drastically reduce the time required for reordering without a trade-off in OBDD-size are described. Overall, this work demonstrates how a tighter integration of applications by using structural information can significantly improve the efficiency of formal verification applications in an industrial setting.
Hydrodynamic processes play a fundamental role in the distribution of salt within mangrove-fringed estuaries and mangrove forests. In this thesis, two hydrodynamic processes and their ecological implications were examined. (1) Passive Irrigation and Functional Morphology of Crustacean Burrows in Rhizophora-forests. The mangrove Rhizophora excludes more than 90% of the seawater salt at water intake at the roots. By means of conductivity methods and resin casting, it was found that crustacean burrows play a key role in the removal of excess salt from the root zone. Salt diffuses from the roots into the burrows, and is efficiently flushed from the burrows by rainwater infiltration and tidal irrigation. The burrows contribute significantly to favourable conditions for the growth of Rhizophora trees. (2) Trapping of Mangrove Propagules due to Density-driven Secondary Circulation in Tropical Estuaries. In North East Australian estuaries, mangrove propagules are drifted upstream by density-driven axial surface convergences. Propagules accumulate in hydrodynamic traps upstream from suitable habitat, where they are trapped at least for the entire tropical dry season. Axial convergences may provide an efficient barrier for propagule exchange across estuaries. In such estuaries, mangrove populations can be regarded as floristically isolated, not unlike island communities, even though the populations lie on a continuous coastline. This effect may contribute to the disjunct distribution observed in some mangrove species. The outcomes of this work contribute to the understanding of the importance of salt as a growth and habitat-restricting factor in the mangrove environment.
Hardware bugs can be extremely expensive, financially. Because microprocessors and integrated circuits have become omnipresent in our daily live and also because of their continously growing complexity, research is driven towards methods and tools that are supposed to provide higher reliability of hardware designs and their implementations. Over the last decade Ordered Binary Decision Diagrams (OBDDs) have been well proven to serve as a data structure for the representation of combinatorial or sequential circuits. Their conciseness and their efficient algorithmic properties are responsible for their huge success in formal verification. But, due to Shannon's counting argument, OBDDs can not always guarantee the concise representation of a given design. In this thesis, Parity Ordered Binary Decision Diagrams are presented, which are a true extension of OBDDs. In addition to the regular branching nodes of an OBDD, functional nodes representing a parity operation are integrated into the data structure, thus resulting in Parity-OBDDs. Parity-OBDDs are more powerful than OBDDs are, but, they are no longer a canonical representation. Besides theoretical aspects of Parity-OBDDs, algorithms for their efficient manipulation are the main focus of this thesis. Furthermore, an analysis on the factors that influence the Parity-OBDD representation size gives way for the development of heuristic algorithms for their minimization. The results of these analyses as well as the efficiency of the data structure are also supported by experiments. Finally, the algorithmic concept of Parity-OBDDs is extended to Mod-p-Decision Diagrams (Mod-p-DDs) for the representation of functions that are defined over an arbitrary finite domain.
The painter Marianne Werefkin (born 1860; died 1938), from the circle of artists known as the Blue Rider (Der Blaue Reiter) in Munich and lifelong companion of Alexej Jawlenskys, lived in Russia and Latvia the first 36 years of her life. She received her artistic education in Moscow and St. Petersburg. Nevertheless the influence of Russian art on her Munich creative phase has been until now been omitted from research literature. Hence it lacks an important basis for the understanding of her creative output. In many respects Marianne Werefkin led the way in bringing the goals of so-called Russian Realism (russischen Realismus) onto another level, one in which the transmission of emotions was seen as a central aspect. The way the pictures of her teacher Ilja Repin had nothing to do with superficial emotion through simple moralistic categorization, but rather the painter demonstrated life's interconnectedness. After a new artistic beginning in Munich Werefkin took out the historical-daily context from her motifs, since, in the spirit of her time, she had recognized that everything visible was illusion. However she made use of actual reality as a repertoire of symbols for her own feelings, representing universal situations and allowing the total picture space to be the bearer of emotions. In that respect she is different from Wassily Kandinsky, who employed abstraction until reference to reality dissolved. Art for Werefkin involved no self-purpose, but should have a positive influence upon the observer. Narrative instruction is pushed to the background through the way it interacts, which depends upon knowledge of psychology and spiritual groups.
Untersuchung der Metamorphosen unter dem Gesichtspunkt der Veränderung auf der metatextuellen, diachronistischen und hypertextuellen Ebene in Ted Hughes' Tales from Ovid; übersetzungstheoretische wie textpragmatische und literaturphilosophische Überlegungen führen zum Schluss, dass die Veränderung der Form und des Stils des Epos die einzig signifikatstreue Form der Konservierung des Geists der Metamorphosen sein kann.
Cancer diagnosis prototypically represents a critical life event and, thus, requires extensive coping efforts by the patients which may be promoted by support received from their social network members. Quantity and quality of received support can be determined by the patients' self-presentation of their coping behavior ("coping-portrayal") and by their attempts at mobilizing support. Until now, research has indicated that a depressive and ruminative coping-portrayal may especially evoke negative emotional reactions in others. The quasi-experimental study presented here focused on the effects of a ruminative coping-portrayal on willingness of others in providing social support and investigated, in particular, if these effects may be counteracted by more or less direct attempts at support mobilization. A sample of 189 middle-aged subjects received fictitious descriptions of an encounter with a "former schoolmate" (protagonist) who discloses that he has recently been diagnosed with cancer. The protagonist's directness of support mobilization (explicit vs. implicit vs. no request of support) as well as his coping-portrayal (with vs. without rumination) were systematically manipulated. Action tendencies with regard to sustained support (e.g., high time-investment) and short-term encouragement as well as the intensity of specific emotions (e.g., sympathy; fear of one's own distress; joy at the other's trustfulness) were considered as dependent variables. Results showed that a ruminative coping-portrayal evoked less sympathy than a coping-portrayal without rumination; moreover, a ruminative way of presenting one's coping behavior induced action tendencies which were described by momentary encouragement rather than by sustained support endeavors. Explicit requests of support reduced subjects' fear of their own distress and mostly increased joy at the protagonist's trustfulness compared to implicit requests. Furthermore, the negative effects of a ruminative coping-portrayal on the subjects' willingness to provide sustained support were compensated by explicit requests for support provision. In general, these results quite convincingly show that the way of activating supportive actions from others can be crucial for support received when facing a critical life event.
Today obesity has been recognized as a disease. Evidence suggests that obesity often has Genetic, environmental, psychological and other factors. Growing evidence points to heredity as a strong determining factor of obesity. The characterization of uncoupling proteins (UCP) represents a major breakthrough of genetic factors towards understanding the molecular basis for energy expenditure and therefore likely to have important implication for the cause and treatment of human obesity. UCPs as mitochondrial anion carriers which creates a pathway that allows dissipation of the proton electrochemical gradient therefore which when deregulated are key risk factors in the development of obesity and other eating disorders. In order to better understand the roles of both UCP2 and UCP3 which considered as prime candidate genes involved in the pathogenesis of obesity, this study elucidate (1) Genomic organization: The human UCP2 (3) gene spans over 8.7 kb (7.5 kb) distributed on 8 (7) exons. Three UCP genes may have evolved from a common ancestor or are the result from gene duplication events. Two mRNA transcripts are generated from hUCP3 gene, the long and short form of hUCP3 is differing by the presence or absence of 37 amino acid residues at the C-terminus. (2) Mutational analysis revealed a mutation in exon 4 of hUCP2 resulting in the substitution of an alanine by a valine at codon 55 and an insertion polymorphism in exon 8 consisted of a 45 bp repeat located 150 bp downstream of the stop codon in the 3'-UTR. The allele frequencies of both polymorphisms were not significantly elevated in a subgroup of children characterized by low Resting Metabolic Rates (RMR). (3) Promoter Analysis showed that the promoter region of hUCP2 lacks a classical TATA or CAAT box. Functional characterization of hUCP2 promoter showed that minimal promoter activity was observed within 65 bp upstream of the transcriptional start site. 75 bp further upstream a strong cis-acting regulatory element was identified which significantly enhanced basal promoter activity. The regulation of human UCP2 gene expression involves complex interactions among positive and negative regulatory elements. the 5"-flanking region of the hUCP3 gene were characterized in which contains both TATA and CAAT boxes as well as consensus motifs for PPRE, TRE, CRE and muscle-specific MyoD and MEF2 sites. Functional characterization identified a cis-acting negative regulatory element between - 2983 and -982 while the region between -982 and -284 showed greatly increased basal promoter activity suggesting the presence of a strong enhancer element. Promoter activity was particularly enhanced in the murine skeletal muscle cell line C2C12 reflecting the tissue-selective expression pattern of UCP3.
