Bestimmung des Bodenreibungsbeiwertes und der Oberflächenreibung eisbedeckter Wasserflächen im Meiningenstrom der Darß-Zingster Boddenkette und Anwendung auf vertikal integrierte hydronumerische Modelle

Schönfeldt, Hans-Jürgen, Raabe, Armin, Baudler, Henning 03 November 2016 (has links) (PDF)
In einem hydronumerischen Modell zur Prognose des Strömungs- und Wasserstandsfeldes flacher Gewässer wird eine auf der Turbulenztheorie basierende Tiefenkorrektur für den Bodenreibungsbeiwertwert eingeführt und auf der Basis von Berechnungen für die DarßZingster Boddenkette überprüft. Für einen ausgewählten Meßpunkt der Darß-Zingster Boddenkette wurde der Reibungsbeiwert sowohl am Boden als auch unter einer Eisschicht experimentell bestimmt. Die Auswirkungen einer Tiefenkorrektur des Reibungsbeiwertes wurden in einem vertikal integrierten hydronumerischen Modell untersucht. Dabei wurden die experimentell bestimmten Reibungsbeiwerte, sowohl für die Reibung am Boden, als auch für die Reibung unter einer Eisschicht im Modell benutzt. Das verwendete Modell zeigt mit den gemessenen Reibungsbeiwerten nach Einführung der Tiefenkorrektur eine bessere Übereinstimmung zwischen Modelldaten und amtlichen Pegelregistrierungen. / For simulation of the flow and water level field in shallow water is introduced a depth correction of the bottom drag coefficient based on the theory of turbulence in a hydronumerical model and tested on calculations for the "Darß-Zingster Boddenkette". The drag coefficient was determined experimentally on the bottom and under ice for a selected measurement point in the "Darß-Zingster Boddenkette". The result of the depth correction was tested with a depth integrated hydronumerical model. The experimentally deterrnined drag coefficient on the bottom and under ice was introduced in the model. The used model shows with the measured drag coefficient after using the depth correction better agreement between the numerically simulated and measured water level.

Vztah mezi zavedením eura a vnímanou inflací v pobaltskýdch republikách / The Relation Between the Euro Cash Changeover and the Perceived Inflation in the Baltic Countries

Orosz, Előd January 2017 (has links)
The relation between the euro cash changeover and the perceived inflation in the Baltic countries Abstract This thesis focuses on the effect of euro cash changeover on inflation perception, and its relation to the inflation measured by central banks or by national statistical offices. We present an analyses of inflation gap in Estonia, Latvia and Lithuania at the euro introduction and detect its determinants by econometric methods. We use Ordinary Least Squares, Random Effects Generalized Least Squares and Fixed Effects estimator. The thesis is divided into two main parts. The first part examines the theoretical background of perceived inflation and focuses at the phenomenon of increased inflation gap at the euro introduction. Second part contains an empirical study on inflation gap. We find out that perceived inflation in Baltic countries does not show such a divergence, as it was presented at the establishment of the Eurozone. Moreover, we find out that education and available income in general has a small, but evincible effect on inflation gap observed at euro introduction.

The monetary value of marine environmental change

Hasselström, Linus January 2016 (has links)
The marine ecosystems are fundamental for human welfare. A number of current environmental pressures need attention, and the formulation of management strategies requires information from a variety of analytical dimensions. The linkage between environmental change and resulting implications for human welfare is one such dimension. This thesis presents studies on welfare implications from hypothetical future policies which improve the state of the marine environment. The method for these studies is economic valuation. The studied scenarios concern eutrophication in the Baltic Sea (including the Kattegat) and oil spill risk from shipping in the Lofoten-Vesterålen area in the Arctic Barents Sea. The thesis shows that the economic benefits from undertaking policies to improve or protect the marine environment in these cases are substantial and exceed the costs of taking measures. In addition to providing new monetary estimates, the thesis also provides new insights concerning 1) what type of scenario to use when valuing an environmental improvement and 2) whether there may exist trade-offs between precision in estimates and the level of ambition with respect to survey instrument complexity and econometric models when conducting valuation studies. The findings suggest an end of an era for studies in which the environmental change is unspecified or based on a single environmental indicator while the actual consequences of the suggested measures are more multifaceted. In contrast, relevant scenarios to study are well-specified and holistic. The thesis further reveals that it might not always be worth the effort to go for the most advanced scenario presentation or statistically best-fitting model specifications. This is something that needs to be further discussed among practitioners in order to allocate valuation resources wisely and not waste resources on unnecessarily elegant valuation studies. / <p>QC 20161011</p>

Sub-regionálna spolupráca a európska integrácia. Postavenie Visegrádskej spolupráce a Baltskej spolupráce v architektúre Európskej únie / Sub-Regional Cooperation and European Integration. The Role of the Visegrad Cooperation and Baltic Cooperation in the Architecture of the European Union

Zelenická, Zuzana January 2007 (has links)
The aim of this work is to analyse the mutual relationship of sub-regional cooperation structures and the dominant integration structure: the European Union. We follow the evolution of mutual relationship between Visegrad Cooperation and the EU from the establishment of such sub-regional cooperation structure until today. Similarly, we analyse the relationship of the Baltic Cooperation and the EU. Later, we compare the evolution of both cooperation types on the background of their integration into the EU and thus identify their specifics. In the final part, we widen the research scope on the whole European Union and even more on the European continent and we try to identify and categorize existing cooperation and integration structures in this wider European region. As a conclusion we introduce brief characteristics of sub-regional cooperation and integration process in Europe in the relation to the EU and suggest future development.

Integrace akciových trhů v baltických zemích / Baltic Stock Market Integration

Stulga, Šarūnas January 2019 (has links)
1 Abstract In this thesis, we present an empirical analysis of integration between the Baltic and global stock markets during the period between 2000 and 2018. This research is spurred by the fact that all three Baltic countries displaying similar positive economic developments over the studied horizon. Using the theoretical and empirical findings from similar research papers, we ground our work for the analysis. Our methodology is based on three different models: DCC-GARCH, total and frequency connectedness, and the Engle-Granger cointegration test. Using these methods, we are able to determine both short- or long-term relationship dynamics. Based on the results from our empirical analysis we were not able to reject the null hypotheses, that the Baltic states have become more integrated between themselves and the global market. At best, our results would suggest a weak form of integration given that there were indeed some notable dynamic changes. Following these results, we provide insight on interdependencies between the Baltic states and their relationships with the global stock markets. Most notable dynamics are captured by the total connectedness measure, which indicates that the Baltic stock markets show a significantly increased connectedness with the global indices, during turbulent times in the...

Internal punishment : a psychoanalytical reading of F.M. Dostoevsky's 'Crime and Punishment' (1866), L. Rebreanu's 'Ciuleandra' (1927) and P. Ackroyd's 'Hawksmoor' (1985)

Ciofu, Natalia January 2018 (has links)
This doctoral thesis examines the representations and dynamics of crime and inner punishment in a range of European literary works of the nineteenth and twentieth centuries: F.M. Dostoevsky’s Crime and Punishment (Преступлeние и наказaние, 1866), L. Rebreanu’s Ciuleandra (1927) and P. Ackroyd’s Hawksmoor (1985), while tracing the developments of crime fiction and the changes in criminal legal system over the span of one hundred and nineteen years. Utilising the methodology of comparative literature, I argue that the interiorized punishment - which I identify, after Foucault, as a new episteme - is a narrative thread that runs through all three novels, and informs much other writings in the same period. Informed by different socio-cultural, temporal, political, and stylistic backgrounds, each novelist utilizes distinct narrative techniques and strategies to configure their protagonists in such a way that permits the reader to get an insight into their psyches. The present study locates the literary tendency to fuse the character of the protagonist/hero and the perpetrator/anti-hero into one narrative entity and examines the literary representation of the factors that trigger the guilt or need for punishment in this entity. To this end, I focus on the narrative structure, temporal framework, geographical setting as well as the protagonists’ relations with other characters within the texts. The idea of self-punishment, its representations and manifestations, is explored through the lens of psychoanalytical theories of Sigmund Freud, Melanie Klein, Jacques Lacan and Otto Rank. My psychoanalytical readings of the texts are furthermore complemented by the theoretical frameworks offered by Mikhail Bakhtinʼs theory of polyphony, Linda Hutcheonʼs account of historiographic metafiction and relevant philosophical perspectives such as Søren Kierkegaardʼs and Jean-Paul Sartreʼs existentialisms.

The role of EFL educators in Turkey in the era of globalisation : an analytical auto-ethnography of an EFL educator turned administrator at IPRIS

Melville, Edmund Christopher January 2015 (has links)
Globalisation, a major aspect of English foreign language (EFL) education in the twenty-first century, can be described as the worldwide circulation of goods, services, and capital as well as information, ideas, and people. EFL educators encounter relentless demands to shift their positions, perspectives, and identities, and to assume many roles because they must accommodate new cultures and people in order to teach in their chosen field. We also have to accommodate differences in ideologically constructed representations of our roles as educators in terms of culture, class, gender, race, and religion within their various contexts. Thus, it can be difficult to determine exactly what one's role is in the context of globalisation. Using an analytic, auto-ethnographic, and naturalistic research design, I purposefully selected five EFL educators (six, including me) and investigated how we fit/belong at IPRIS, what our perceived roles as EFL educators are, and how our roles as EFL educators in full relate to globalisation. Bourdieu's experiences in Algeria, his theories arising from them, and Bhabha's notion of the third space, which is synchronistic with postcolonial theory, formed my theoretical framework. I collected data through interviews, reflexive journal, and critical incidents that were member checked to ensure trustworthiness. The inductively oriented data analysis yielded the themes and categories that are the foundation of this research. The emergent findings in this research were key in showing how the backgrounds of the participants positioned each of us so differently one from another as EFL educators. The varied ways in which the participants have discerned their roles as individuals and as EFL educators unfolded. The explicit commentary of all the participants in this study (including me) reflected a deep commitment to the needs of the students at IPRIS as we expressed our views on our roles. This research revealed the knowledge that I have built concerning myself, both in my context and in relation to others, by investigating the spaces in between coming and going, participant and researcher, educator and administrator; it has helped to reveal the fault-line spaces that shift in perspective and has thus helped me find my fit/belonging. The flipped researcher-participant roles allowed me to explain and further interrogate my own views of my role at IPRIS, as the primary participant, in relation to the secondary participants' perceptions of their roles. This research has also revealed both the positioning of the EFL educator and the space that English occupies globally, in which it has an opposing logic that sometimes results in hybridisation. The secondary participants' comments in this study reflected their perception that they needed to bring information from their prior experiences, both as educators and as people living in the world, to bear on their primary role of teaching English to Turkish students. Thus, none of the participants felt that they were enabled in their role, as all reported that they needed to add old experiences with the new in order to teach their assigned students and to navigate the terrain at IPRIS. Drawing from the definition of globalisation in the literature, I was also able to use the participants' current perceptions of the role of English as a global language to reveal their relationship to globalisation. As a result of my thesis research, I can recommend the use of analytic auto-ethnography as a form of professional development and evaluation. The degree of reflexivity involved can enable EFL educators at IPRIS and elsewhere to raise their own awareness of other people and of their institutional and cultural contexts.

Komparativní analýza zahraničních politik pobaltských států / Comparative analysis of foreign policies of the Baltic states

Gromilova, Anna January 2011 (has links)
The aim of the diploma thesis is to analyze and to compare the foreign policies of Estonia, Lithuania and Latvia in the period from 1991 until 2004 and to reach a conclusion, whether the frequent and very common generalization of the foreign policies of those states is correct. The first part of the paper explores the main approaches to the analysis of foreign policy and state's national interest. In this part of the paper, the appoach to analysis of the state's national interest, offered by the Copenhagen school of theory is chosen, and this approach is then used in the second chapter of the diploma. The second part of the paper, examines the threats of Estonia, Latvia and Lithuania in political, societal, military and economic sectors. Finally, the conclusion describes the results of the analysis of each sector and provides the assessment and comparison of the main problems of Estonia, Latvia and Lithuania and of the ways in which the states were trying to solve them in the chosen time period. It is shown, that despite the fact, that Estonia, Latvia and Lithuania were often facing similar challenges, they did also have an abundant number of different and specific problems of their own, were not able to work in concert, and often showed resistance to be deemed as "Baltic". This leads to the conclusion that treating their foreign policies as a joint "Baltic foreign policy" is incorrect and can be misleading.

Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

Malmvärn, Anna January 2007 (has links)
<p>Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. Furthermore, there are indications that certain polyhalogenated compounds similar in structure to man-made POPs are produced by the biota present in this sea. In the late 1990’s both methoxylated polybrominated diphenyl ethers (MeO-PBDEs) and hydroxylated-PBDEs (OH-PBDEs) were identified in fish and seals living in this environment. OH-PBDEs can originate from metabolism of PBDEs, but both OH- and MeO-PBDEs are also known to be natural products in marine environments. Another group of POPs, the polybrominated dibenzo-<i>p</i>-dioxins (PBDDs), are not produced commercially, but are known to be by-products of chemical industry and of the combustion of, e.g., brominated flame retardants (BFRs). In contrast to the OH- and MeO-PBDEs, PBDDs have not previously been shown to be natural products, although certain related compounds have been indicated to have a natural origin.</p><p>This thesis describes the identification of PBDDs, OH-PBDEs and MeO-PBDEs in algae, blue mussels and fish living in the Baltic Sea. Several of these compounds were also detected in cyanobacteria. Moreover, PBDDs were present in fish, mussels, shrimp and crabs from different regions of the Baltic Sea and from the west coast of Sweden, but not in organisms from freshwater environments. The levels of these compounds in Baltic fish generally exceeded those of their chlorinated analogues. The origin of the PBDDs identified is somewhat unclear, but the high levels present in blue mussels and the pattern of congeners observed indicate natural production. The presence of PBDDs, OH-PBDEs and MeO-PBDEs in fish and shellfish constitutes a potential risk to both humans and wildlife and requires further investigation.</p>

Ecotoxicological effects from three antifouling paints on the red macroalga <em>Ceramium tenuicorne.</em>

Krantz-Frid, Madelene January 2009 (has links)
<p>Antifouling paints are applied on vessels to prevent growth of fouling organisms such hasbarnacles. Presently, there are a number of different paints available on the Swedish marketwith different strategies and active substances. The paints might work by either continuouslyreleasing biocides or physically by peeling off or provide an easily cleansed surface whereorganisms cannot attach. The physically working paints do not need to register an activesubstance since its purpose is not to affect living organisms by a chemical or biological modeof action. In this study, two commercially available paints, the copper-based Fabi 3959(International Paint Ltd) and physically eroding, biocide-free labelled Mille Light (HempelFärg AB) were compared to Hard Racing superior, containing copper and the forbiddensubstance Tributyltin. Fabi International is only allowed to be used on the Swedish west coastdue to 6% added as active substance while the biocide-free Mille Light is eligible for eastcoast usage. The toxic effect from respective paint was investigated by assembling a growthinhibition test with the red macro alga Ceramium tenuicorne. The results show that all thestudied paints had a negative effect on growth and therefore leaked substances inconcentrations high enough to be harmful to the alga. The toxic response differed with theeffect on growth being in the following order, Hard racing superior>Fabi >Mille Light.Implications regarding the current legalization involving biocide-free labelled antifoulingpaints are discussed.</p>
