Surpassing the national perspective usually adopted, the authors confirmed the existence of a pattern of population distribution common to the whole Iberian Peninsula in the long run. This pattern is clearly associated with geographical factors. These variables seem to have more weight in explaining changes between 1877/78 and 1940 than in the period from 1940 to 2001. The observation of the cross-border region has shown that proximity to the frontier has not generated any distinct pattern of population density on either side of the boundary line. The spatial coherence of the observed phenomena throughout the Peninsula and of its evolution, independent of the border between states, reinforces the importance of geographic factors in their explanation. At the same time, this verification opens up new issues related to the effect of national political and economic policies.

This thesis examines the suitability of VaR in foreign exchange rate risk management from the perspective of a European investor. The suitability of four different VaR models is evaluated in respect to have insight if VaR is a valuable tool in managing foreign exchange rate risk. The models evaluated are historical method, historical bootstrap method, variance-covariance method and Monte Carlo simulation. The data evaluated are divided into emerging and developed market currencies to have more intriguing analysis. The foreign exchange rate data in this thesis is from 31st January 2000 to 30th April 2014. The results show that the previously mentioned VaR models performance in foreign exchange risk management is not to be considered as a single tool in foreign exchange rate risk management. The variance-covariance method and Monte Carlo simulation performs poorest in both currency portfolios. Both historical methods performed better but should also be considered as an additional tool along with other more sophisticated analysis tools. A comparative study of VaR estimates and forward prices is also included in the thesis. The study reveals that regardless of the expensive hedging cost of emerging market currencies the risk captured by VaR is more expensive and thus FX forward hedging is recommended

Im Wassereinzugsgebiet der Aar zwischen Taunuskamm und Limburger Becken wurden 242 Erosionsschluchten, so genannte Runsen kartiert. Die vorgefundenen geomorphologischen Formen sind zum Teil mehr als 15 Meter tief, kerben- oder kastenförmig. Einige führen ein zeitweise oder ständig fließendes Gerinne. Die Untersuchung acht verschiedener Einzelbeispiele mit geomorphologischen, bodenkundlichen und kulturhistorischen Methoden ergab, dass die Erosionsschluchten in geschichtlicher Zeit entstanden sind. Damit wurden die Ergebnisse von BORK 1988, 1985, BORK et al. 1998, BAUER 1995, 1993, SEMMEL 1963, HEMPEL 1954, 1954 und HARD 1970 weitgehend bestätigt. Die Runsen an der Aar und ihrer Nebenbäche sind das Ergebnis exzessiver Erosionsprozesse, die in Folge einer erheblichen Übernutzung der Landschaft durch Köhlerei, Eisenerzverhüttung und Landwirtschaft hauptsächlich im 17. und 18. Jahrhundert ausgelöst wurden. Dabei kommt der seit 1656 betriebenen Michelbacher Hütte als landesherrliches Eisenwerk eine besondere Rolle zu. Ein weiterer Einfluss geht auf die spezifische Geofaktorenkonstellation im Untertaunus zurück. Die dort verbreiteten stark tonig verwitterten Schiefer und erodierten Parabraunerden fördern den Oberflächenabfluss, der während zeitweise auftretender Starkregenereignisse an den Hängen zum Einreißen von Erosionsschluchten führen kann . Zur Untersuchung des Phänomens wurden sowohl geomorphologische und bodenkundliche als auch historisch-kulturlandschaftgenetische Methoden herangezogen. Neben der bodenkundlichen Beprobung zahlreicher Aufschlüsse wurden auch Analysen mittels der Radiokarbonmethode, Schwermineralanalysen, Kohlholzspektren historischer Meilerplätze und die Auswertung von Archivunterlagen als Methoden herangezogen. Als grundlegendes Ergebnis liefert die vorliegende Arbeit einen umfassenden Abriss der Nutzungsgeschichte im Wassereinzugsgebiet der Aar von vorgeschichtlicher Zeit bis zum heutigen Tage. Zudem werden die naturräumlichen Einflussfaktoren, die die Entstehung von Erosionsschluchten erst ermöglichen, auf umfassende Weise dargestellt. Zwei Exkurse behandeln die Bedeutung der spätmittelalterlichen Landwehr bei Hennethal, die während der Geländearbeiten entdeckt wurde sowie die Entstehung und zeitliche Einordnung der Auelehme im Aartal.

This research study offers a critical assessment of NIH's Consensus Development Program (CDP), focusing upon its historical and valuative bases and its institutionalization in response to social and political forces. The analysis encompasses systems-level, as well as interpersonal factors in the adoption of consensus as the mechanism for resolving scientific controversies in clinical practice application. Further, the evolution of the CDP is also considered from an ecological perspective as a reasoned adaptation by NIH to pressures from its supporters and clients for translating biomedical research into medical practice. The assessment examines federal science policy and institutional designs for the inclusion of the public interest and democratic deliberation.^ The study relies on three distinct approaches to social research. Conventional historical methods were utilized in the interpretation of social and political influences across eras on the evolution of the National Institutes of Health and its response to demands for accountability and relevance through its Consensus Development Program. An embedded single-case study was utilized for an empirical examination of the CDP mechanism through five exemplar conferences. Lastly, a sociohistorical approach was taken to the CDP in order to consider its responsiveness to the values of the eras which created and shaped it. An exploration of organizational behavior with considerations for institutional reform as a response to continuing political and social pressure, it is a study of organizational birth, growth, and response to demands from its environment. The study has explanatory import in its attempt to account for the creation, timing, and form of the CDP, relative to political, institutional, and cultural pressures, and predictive import thorough its historical view which provides a basis for informed speculation on the playing out of tensions between extramural and intermural scientists and the current demands for health care reform. ^

Com o desenvolvimento deste projeto de pesquisa Religião profética e crise política: estudo da sociedade norte-israelita à luz de Oséias 9,1-9 queremos identificar que momento de crise foi essa pelo qual passou a sociedade norte-israelita no século VIII a.C., e qual seria o background oseânico que teria funcionado como um verdadeiro leitmotiv em sua vida profética. Ao invés de partirmos de uma regressão, i.é., de um estudo dedutivo (método descendente), devido à falta de material e também pela complexidade do trabalho, farei o inverso, partirei da teoria que hoje é plenamente aceita no meio acadêmico. Fundado numa metodologia que privilegia os resultados obtidos a partir dos mais rigorosos dados historiográficos métodos históricos críticos e pesquisas arqueológicas este projeto de pesquisa utilizará o método indutivo, i.é., partiremos de um processo ascendente. O desafio está em delinear a trajetória autonômica da monarquia norte-israelita, procurando estabelecer quais foram os momentos mais marcantes desta caminhada histórica, suscetíveis de forjar a manifestação de profetas como Amós, Oséias, Miquéias e tantos outros. Como objeto principal de nossa pesquisa, o foco estará sobre o profeta Oséias que soube como nenhum outro antes dele, fazer uma síntese entre religião e vida, i.é., soube desenvolver critérios éticos que serviram como parâmetro avaliativo de pureza da religião javista
