3A1685888011.jsonld | Frame by frame : a materialist aesthetics of animated cartoons | At publication date, a free ebook version of this title will be available through Luminos, University of California Press's Open Access publishing program. Visit www.luminosoa.org to learn more. In this beautifully written and deeply researched study, Hannah Frank provides an original way to understand American animated cartoons from the Golden Age of animation (1920-1960). In the pre-digital age of the twentieth century, the making of cartoons was mechanized and standardized: thousands of drawings were inked and painted onto individual transparent celluloid sheets (called "cels") and then photographed in succession, a labor-intensive process that was divided across scores of artists and technicians. In order to see the art, labor, and technology of cel animation, Frank slows cartoons down to look frame by frame, finding hitherto unseen aspects of the animated image. What emerges is both a methodology and a highly original account of an art formed on the assembly line Frontmatter -- Contents -- List of Illustrations -- Foreword : Hannah Frank's Pause / Gunning, Tom -- Editor's Introduction / Morgan, Daniel -- Acknowledgments -- Introduction: Looking at Labor -- 1.

3A1655568620.jsonld | Die Regierung der Gesundheit : Fragmente einer Genealogie liberaler Gouvernementalität | What is behind our health-related decisions? Discourses on health around middle-class self-practice, medical management, and the political technologies of the 19th century. Michel Foucault suchte bereits 1983 nach den Rationalitäten, die unseren gesundheitlichen Wahlentscheidungen zu Grunde liegen. Diese Frage stellt sich heute noch dringender, bedenkt man den neoliberalen Wandel von Gesundheitsdiskursen in den letzten Jahrzehnten. Diese Diskurse finden ihre Vorfahren in der religiösen und bürgerlichen Selbstpraxis sowie in der ärztlichen Praxis der Beratung und Überzeugung. Irene Poczka betrachtet diese als Regierungsweisen, die schließlich auch die politischen Techniken beeinflussten, mit denen die Gesundheit der Bevölkerungen reguliert werden sollte. Sie stellt fest: Im Europa des 19. Jahrhunderts lassen sich überall diskursive Fragmente einer Genealogie liberalen Regierens von Gesundheit ausmachen. | [

3A773153705.jsonld | A critical assessment of the socio-economic reintegration process of ex-combatants ten years after the war in Sierra Leone | This study examines the current socio-economic status of the ex-combatants 10 years after the conflict in Sierra Leone. It examines the job opportunities, political space, relationship with community members, challenges faced, social networks involved in, relationship with former colleagues, access to land and other issues that are significant in the reintegration process of ex-combatants. It further studies the national socio-economic environment and how ex-combatants are faring in the overall post-war recovery process in Sierra Leone. Special focus lies on the Disarmament, Demobilization and Reintegration of Ex-Combatants (DDR) programme which was part of the Lome Peace Agreement signed in 1999. The study also comes up with recommendations as to how the challenges currently faced by ex-combatants could be overcome. | [

3A871821672.jsonld | Erklärung der Resignationstendenz von Lehrkräften durch individuelle Tätigkeits- und Kompetenzprofile und bildungspolitische Rahmenbedingungen | Teachers play an important role for children’s success at school as well as for the implementation and effectiveness of education policy reforms. However, in the national and international context the teaching profession belongs to those professions with a particularly high psychological strain, which can manifest itself in long-term incapacities to work as well as in poor teaching and a bad school climate. The study analyses if teachers’ resignative tendencies, which play an important role in the development of burnout symptoms, can be explained through individual and education policy factors and which aspects are more decisive. The theoretical explanatory model of teachers’ resignative tendencies is tested using structural equation modelling. The analyses show that individual as well as education policy factors explain teachers’ resignative tendencies to a certain extent, whereby the perceived school climate and teachers’ activity and competency profiles play a particularly important role. <engl.> Lehrkräfte allgemein- und berufsbildender Schulen nehmen eine zentrale Rolle für den schulischen Erfolg von Kindern und Jugendlichen sowie für die Umsetzung und Wirksamkeit bildungspolitischer Reformen ein.

3A785332928.jsonld | Integrative methods for reconstruction of dynamic networks in chondrogenesis | Application of human mesenchymal stem cells represents a promising approach in the field of regenerative medicine. Specific stimulation can give rise to chondrocytes, osteocytes or adipocytes. Investigation of the underlying biological processes which induce the observed cellular differentiation is essential to efficiently generate specific tissues for therapeutic purposes. Upon treatment with diverse stimuli, gene expression levels of cultivated human mesenchymal stem cells were monitored using time series microarray experiments for the three lineages. Application of gene network inference is a common approach to identify the regulatory dependencies among a set of investigated genes. This thesis applies the NetGenerator V2.0 tool, which is capable to deal with multiple time series data, which investigates the effect of multiple external stimuli. The applied model is based on a system of linear ordinary differential equations, whose parameters are optimised to reproduce the given time series datasets. Several procedures in the inference process were adapted in this new version in order to allow for the integration of multiple datasets. Network inference was applied on in silico network examples as well as on multi-experiment microarray data of mesenchymal stem cells. The resulting chondrogenesis model was evaluated on the basis of several features including the model adaptation to the data, total number of connections, proportion of connections associated with prior knowledge and the model stability in a resampling procedure. Altogether, NetGenerator V2.0 has provided an automatic and efficient way to integrate experimental datasets and to enhance the interpretability and reliability of the resulting network. In a second chondrogenesis model, the miRNA and mRNA time series data were integrated for the purpose of network inference. One hypothesis of the model was verified by experiments, which demonstrated the negative effect of miR-524-5p on downstream genes. | [

3A1010583662.jsonld | Savanna dynamics under extreme conditions : Insights from a mathematical model | Savannas cover a broad geographical range across continents and are a biome best described by a mix of herbaceous and woody plants. The former create a more or less continuous layer while the latter should be sparse enough to leave an open canopy. What has long intrigued ecologists is how these two competing plant life forms of vegetation coexist. Initially attributed to resource competition, coexistence was considered the stable outcome of a root niche differentiation between trees and grasses. The importance of environmental factors became evident later, when data from moister environments demonstrated that tree cover was often lower than what the rainfall conditions would allow for. Our current understanding relies on the interaction of competition and disturbances in space and time. Hence, the influence of grazing and fire and the corresponding feedbacks they generate have been keenly investigated. Grazing removes grass cover, initiating a self-reinforcing process propagating tree cover expansion. This is known as the… | [

3A77857072X.jsonld | The Northeast Greenland Margin : tectonic evolution | The Norwegian-Greenland Sea (NGS) is an area of increasing interest. Here, the North Atlantic Current continues the Gulf Stream into the NGS. The warm ocean current plays an important role for the world's climate and influences the environment of the global Earth system. Calculations of climate models for the future based on the tectonic evolution of the NGS in the past. Based on few geoscientific data, the tectonic evolution of the NGS and the NE Greenland margin remains controversial. In the summer of 2009, the Alfred Wegener Institute acquired geophysical data - two seismic refraction lines as well as gravity data, measured in parallel to the seismic refraction lines - along the NE Greenland margin (Boreas Basin and offshore Kong Oscar Fjord (KOF)) during the ARK-XXIV/3 expedition. In addition, further gravity data (Arctic Gravity Project) were available and used within this study. Summarising the results, we could develop crustal models for the Boreas Basin and offshore KOF, using the seismic refraction data and the gravity data. Furthermore, a complex 3D gravity model of the NE Greenland margin was calculated, using the crustal models and further published data as boundary conditions. Following our conclusions, the structure of thin oceanic crust (3 km crustal thickness, absence of oceanic layer 3) in the Boreas Basin and along the ultraslow spreading Knipovich Ridge is more heterogeneous than previously thought. For the accretion of 9 km thick oceanic crust offshore KOF, the rift history of NE Greenland (extensive rifting before continental breakup) is more important than higher mantle temperatures caused by the Iceland Hotspot. Therefore, the Iceland Hotspot has smaller influence on the oceanic crustal accretion than previously thought. This might be further indicated by a 3 km thick high-velocity lower crust below the continent-ocean transition zone of KOF which is formed by enhanced melt generation along the nearby Jan Mayen Fracture Zone. | [

3A663597463.jsonld | Optimization of resonances for multilayer x-ray resonators | Resonances in open systems can be described by eigenvalue problems with a radiation condition at infinity and arise in various fields including acoustics, classical mechanics, quantum mechanics, and x-ray physics. This thesis focusses on the optimization of resonances for multilayer x-ray resonators which consist of several layers and support certain resonant states. These resonant states can be excited by x-ray beams under special grazing angles of incidence (corresponding to resonant frequencies of the system) leading to a very high field enhancement inside the system compared to the incident field. X-ray resonators or waveguides can be used for filtering, guiding, and concentration of x-rays, which is for example useful in nanoscale x-ray structure analysis and x-ray imaging. The multilayer structures can be characterized by the refractive index n. We want to find a function n for which the field enhancement in the multilayer structure for a resonant angle of incidence is maximized subject to side constraints on n. For the optimization problem we use an objective function involving complex resonances and corresponding resonance functions. Analytic expressions for the derivatives of resonances and resonance functions with respect to n are derived using perturbation theory of linear operators. As a side product, approximation formulas for the reflectivity are obtained, in particular a mathematical justification for the widely used kinematic approximation. Higher order Taylor approximations and Padé approximations lead to significant improvements of the standard approximation formulas, especially close to the critical angle. We explain how the optimization problem can be discretized and finish with numerical computation leading to improved multilayer x-ray resonators for several situations. | [

3A1662464215.jsonld | Application of amine transaminases in the chemoenzymatic synthesis of chiral amines using isopropylamine as amine donor | Amine transaminases are versatile biocatalysts for the production of pharmaceutically and agrochemically relevant chiral amines. They represent an environmentally benign alternative to waste intensive transition metal catalysed synthesis strategies, especially because of their high stereoselectivity and robustness. Therefore, they have been frequently used in the (chemo)enzymatic synthesis of amines and/or became attractive targets for enzyme engineering especially in the last decade, mainly in order to enlarge their substrate scope. Certainly, one of the most notable examples of amine transaminase engineering is the manufacturing of the anti-diabetic drug Sitagliptin in large scale after several rounds of protein engineering. Thereby, the target amine was produced in asymmetric synthesis mode which is the most convenient and favored route to a target chiral amine, starting from the corresponding ketone. The choice of the amine donor is highly relevant for reaction design in terms of economical and thermodynamic considerations. For instance, the use of alanine as the natural amine donor is one of the most common strategies for the amination of target ketones but needs the involvement of auxiliary enzymes to shift the reaction equilibrium towards product formation. In fact, isopropylamine is probably one of the most favored donor molecules since it is cheap and achiral but it is supposed to be accepted only by a limited number of amine transaminases.

3A617229325.jsonld | The Martian moon Phobos : a geodetic analysis of its motion, orientation, shape, and physical parameters | Mars is accompanied by two small natural satellites. Deimos, the smaller of the two, is orbiting at a greater distance from Mars while Phobos revolves around the planet at a mean altitude of approximately 6,000km with respect to the Martian surface, deep in the gravity field of the planet. An in-depth study of the irregular shaped moon Phobos was commenced due to remaining questions on its orbital motion, shape, and physical parameters based on new high resolution images of the Super Resolution Channel (SRC) and the High Resolution Stereo Camera (HRSC) which are part of the European Mars Express Mission (MEX). Parameters of ephemerides models were questioned after the finding of large discrepancies of Phobos' position to astrometric observations. During the course of this study astrometric measurements were made in fly-by images of Phobos and through observations of Phobos' shadow on the Martian surface. While results of the latter analysis led to largely scattered differences compared to orbit prediction models with high uncertainties, the fly-by observations were in agreement with the ephemerides models within the error bands. Offsets were rather consistent and systematic indicating that Phobos is ahead of its predicted position by approximately 2 km. To be able to model the irregular shape of Phobos by means of different techniques - namely a digital terrain model and a model based on spherical harmonic functions - a new global control point network was established. The 665 object point coordinates with respect to the Phobos body-fixed coordinate frame were determined through observations in 53 SRC and 16 Viking Orbiter images ... | [

3A1843619059.jsonld | Investigation of ancient proteins in archaeological material | Although several studies have positively identified dairy proteins from ancient dental calculus, other dietary protein identifications are exceedingly rare. The manuscripts included in this thesis include the identification of 20 different dietary proteins that could be taxonomically identified to the species level from 10 different species. One of our primary goals for this thesis was to evaluate any potential biases in our dietary protein recovery, and to gain a deeper understanding of the factors that influence dietary protein preservation within dental calculus. Although our sample sizes are small, we did find evidence of biases in the types of proteins we have recovered thus far. All proteins identified were potential allergens with IgE binding sites, low monomer molecular weight, resistance to changes in pH and temperature, and resistance to degradation through enzymatic proteolysis. The identified proteins primarily had functions in host defense or storage. | [

3A1681400332.jsonld | Diakonie ist Kirche : zur Notwendigkeit der Genese einer Diakoniekirche | In the Protestant understanding, a church has to renew itself continuously. In the 21st century, Protestant churches have a high reputation but few bonding forces. The results of surveys among churchmen are obvious: The perception of the church in society derives from welfare and social work (diaconia). In times of a post-traditional people’s church, the question arises of whether the church will be a church of welfare and social work (diaconia) in the future. Reflecting on the countrywide disappearance of churches in Eastern Germany, Matthias Fichtmüller formu-lates the thesis that in future entrepreneurial welfare and social work will take over the tasks of churches. He outlines the conflicts between the institutional church and welfare and social work, and develops a nuanced understanding of church membership. Welfare and social work are not replacing the institutional church but are an enriching addition to it. They are a place for people who cannot find a home in the national churches any more. Nach evangelischem Verständnis muss sich die Kirche beständig verändern. Die evangelischen Kirchen besitzen im 21. Jahrhundert hohe Reputation, doch geringe Bindungskräfte. Die Ergebnisse der Kirchenmitgliedschaftsuntersuchungen (KMU) sprechen seit Jahrzehnten eine eindeutige Sprache: Die Wahrnehmung der Kirche in der Gesellschaft erfolgt über diakonische Aktivitäten. Im postvolkskirchlichen Kontext stellt sich die Frage, ob die Kirche der Zukunft eine Diakoniekirche ist. In Reflexion der zunehmenden flächendeckenden Entkirchlichung in Ostdeutschland stellt Matthias Fichtmüller die These auf, dass die unternehmerische Diakonie künftig Aufgaben der Kirche übernehmen kann. Dabei werden die Konflikte zwischen verfasster Kirche und Diakonie beleuchtet und ein neues, gestuftes Mitgliedschaftsverständnis entwickelt. Diakoniekirche löst nicht die verfasste Kirche ab, doch sie ist ein bereicherndes Additiv zu den bisherigen kirchlichen Strukturen. In ihr können sich Menschen wiederfinden, die in den Landeskirchen keine Heimat haben. | [

It represents a significant step forward in our ability to accurately describe the finite temperature properties of materials. In principle, the macroscopic phases of matter are related to the microscopic interactions of atoms by statistical mechanics and the partition function. In practice, direct calculation of the partition function has proved infeasible for realistic models of atomic interactions, even with modern atomistic simulation methods. The thesis also shows how the output of nested sampling calculations can be processed to calculate the complete PVT (pressure–volume–temperature) equation of state for a material, and applies the nested sampling algorithm to calculate the pressure–temperature phase diagrams of aluminium and a model binary alloy.

3A1788386965.jsonld | Entrepreneurship: the role of gender, perceptions, and institutions | hile women's evolving contribution to entrepreneurship is irrefutable, in almost all nations, gender disparity is an existing reality of entrepreneurship. Social and economic outcomes make women entrepreneurship an important area for scholars and governments. In attempts to find reasons for this gender disparity, academic scholars evaluated various factors and recognised perceptual variables as having outstanding explanatory value in understanding women's entrepreneurship. To advance our knowledge of gender disparity in entrepreneurship, the present study explores the influence of entrepreneurial perceptual variables on women's entrepreneurship and considers the critical role of country-level institutional contexts on the women's entrepreneurial propensity. Therefore, this study examines the impact of perceptual variables in different nations. It also offers connections between entrepreneurial perceptions, women entrepreneurship, and institutional contexts as a critical topic for future studies. Drawing on the importance of perceptual factors, this dissertation investigates whether and how their perception of entrepreneurial networks influences the individuals' decision to initiate a new venture. Prior scholars considered exposure to entrepreneurial role models as one of the most influential factors on the women's inclination towards entrepreneurship; thus, a systemized analysis makes it possible to identify existing research gaps related to this perception. Hence, to draw a clear picture of the relationship between entrepreneurial role models and entrepreneurship, this dissertation provides a systemized overview of prior studies. Subsequently, Chapter 2 structures the existing literature on entrepreneurial role models and reveals that past literature has focused on the different types of role models, the stage of life at which the exposure to role models occurs, and the context of the exposure. Current discourse argues that the women's lower access to entrepreneurial role models negatively influences their inclination towards entrepreneurship. Additionally, although the research on women entrepreneurship has proliferated in recent years, little is known about how entrepreneurial perceptual variables form women's propensity towards entrepreneurship in various institutional contexts. The work of Koellinger et al. (2013), hereafter KMS, is one of the most influential papers that investigated the influence of perceptual variables, and it showed that a lower rate of women entrepreneurship is associated with a lower level of their entrepreneurial network, perceived entrepreneurial capability, and opportunity evaluation and with a higher fear of entrepreneurial failure. Thus, this dissertation replicates the work of KMS. Chapter 3 explicitly investigates the influence of the above perceptions on women's entrepreneurial propensity. This research has drawn data from the Global Entrepreneurship Monitor, a cross-national individual-level data set (2001-2006) covering 236,556 individuals across 17 countries. The results of this chapter suggest that gender disparities in entrepreneurial propensity are conditioned by differences in entrepreneurial perceptual variables. Women's lower levels of perceived entrepreneurial capability, entrepreneurial role models and opportunity evaluation and their higher fear of failure lead to lower entrepreneurial propensity. To extend and generalise the relationship between perceptions and women's entrepreneurial propensity, in Chapter 4, two studies are conducted based on replicated research. Extension 1 generalises the results of KMS by using the same analysis on more recent data. Accordingly, this research implemented the same analysis on 372,069 individuals across the same countries (2011-2016). The recent data show that although gender disparity became significantly weaker, the gender gap is still in men's favour. However, similarly to the replicated study, this research revealed that perceptual factors explain a larger part of the gender disparity. To strengthen prior empirical evidence, in extension 2, utilising a sample of 1,029,863 individuals from 71 countries (2011-2016), the study conducted the same measures and analysis in a more global setting. By including developing countries, gender disparity in entrepreneurial propensity decreased significantly. The study revealed that the relative significance of the influences of perceptions' differs significantly across nations; however, perceptions have a worldwide effect. Moreover, this research found that the ratio of nascent women entrepreneurs in less developed countries to those in more developed nations is 2. More precisely, a higher level of economic development negatively influences the impact of perceptions on women's entrepreneurial propensity. Whereas prior scholars increasingly underlined the importance of perceptions in explaining a large part of gender disparities in entrepreneurship, most of the prior investigations focused on nascent (early-stage) entrepreneurship, and evidence on the relationship between perceptions and other types of self-employment, such as innovative entrepreneurship, is scant. Innovation is a confirmed key driver of a firm's sustainability, higher competitive capability, and growth. Therefore, Chapter 5 investigates the influence of perceptions on women's innovative entrepreneurship. The chapter points out that entrepreneurial perceptions are the main determinants of the women's decision to offer a new product or service. This chapter also finds that women's innovative entrepreneurship is associated with the country's specific economic setting. Overall, by underlining the critical role of institutional contexts, this dissertation provides considerable insights into the interaction between perceptions and women entrepreneurship, and its results have implications for policymakers and practitioners, who may find it helpful to consider women entrepreneurship in systemized challenges. Formal and informal barriers affect women's entrepreneurial perceptions and can differ from one country to the other. In this sense, it is crucial to design operational plans to mitigate formal and stereotypical challenges, and thus, more women will be able to start a business, particularly in developing countries in which women significantly comprise a smaller portion of the labour markets. This type of policy could write the "rules of the game" such that these rules enhance the women's propensity towards entrepreneurship. | [

3A750026065.jsonld | The presence of the past in the novels of Toni Morrison | Hauptbeschreibung: After decades of research into the role of memory, trauma, and historiography in her work, to say that Toni Morrison's novels deal with the presence of the past may seem like a truism. But the complexity of Morrison's vision originates in her understanding of the nature of this past as both individual and collective. This study approaches Morrison's more recent novels on the basis of both literary analysis and sociological theory: drawing on the work of Pierre Bourdieu and Norbert Elias, it shows that the presence of the past in her work unfolds not only in images | [

3A671918125.jsonld | Involvement of two nitric oxide-associated genes, NOA1 and GSNOR, in Nicotiana attenuata's resistance to the specialist insect herbivore Manduca sexta | Nitric oxide-associated protein 1 (NOA1) is involved in various abiotic stress responses and is required for plant resistance to pathogen infections. The first chapter of this dissertation explores for the first time the role of NOA1 in plant-herbivore interactions. We created NOA1-silenced Nicotiana attenuata plants (irNaNOA1), which had highly decreased photosynthesis rates. We further examined plant defense traits against its specialist herbivore Manduca sexta by treating WT and irNaNOA1 plants with mechanical wounding and M. sexta oral secretions (OS). NOA1-silenced plants showed elevated levels of herbivory-induced jasmonic acid (JA), but decreased JA-isoleucine conjugate (JA-Ile) levels that did not result from compromised JAR (jasmonic acid resistant) activity in irNOA1 plants. Moreover, nitrogen-rich defensive compounds, nicotine and trypsin proteinase inhibitors (TPI), did not differ between WT and irNaNOA1 plants. In contrast, concentrations of most carbon-based defensive compounds were lower in these plants than in WT plants, although the levels of chlorogenic acid were not changed. Therefore, silencing NOA1 alters the allocation of carbon resources within the phenylpropanoid pathway. These data suggest the involvement of NOA1 in N. attenuata’s defense against M. sexta attack, and highlight its role in photosynthesis, and biosynthesis of jasmonates and secondary metabolites. | [

3A1652049533.jsonld | Spaces for Jihād : Indian Muslims and Conceptions of Citizenship | This thesis deals with the question of how Indian Muslims make use of the spaces and channels granted by the democratic framework to accommodate their Islamic identity with the secular one, and to what extent their Islamic identity is conceived (or perceived) as either conducive or conflicting with the political setting they live in. By comparing between a majority and minority setting, an analysis of how the socio-political context shapes citizens’ perceptions of multiple variables such as their sense of political efficacy, agency, conception of citizenship rights and belief in democracy is undertaken. | [

3A848109902.jsonld | Essays on consumers' perceptions and valuations of health-enhancing attributes in food products | The complexity and controversy of research outcomes in the field of consumer perceptions and valuations of health-enhancing attributes in food products motivated this dissertation. This controversy arises from unclear connection between income levels and the demand for functional foods, disputed values of health-enhancing attributes for consumers, and increasing complexity in consumers’ decision-making. Thus, the research presented in this dissertation aimed at developing evidence on consumers’ perceptions and valuations of health-enhancing attributes in food products, advancing the methodological approach for studying consumer food choices, and summarizing existing knowledge on the topic. The originality of this dissertation arises from: (i) systematic review of the literature employing meta-analysis; (ii) modified methodological approach to the analysis of the empirical data; (iii)specific empirical evidence from an understudied region (Russia); and (iv) comparative analysis of qualitative data in a cross-cultural context. willingness to pay; experimental auction; health-enhancing food; functional food; random utility; reference point; meta-analysis; trust Zahlungsbereitschaft; experimentelle Auktion; gesundheitsfördernde Lebensmittel; funktionelle Lebensmittel; random utility Modelle; reference points effects Modelle; Metaanalyse; Vertrauen Die Komplexität und Kontroversen über Verbraucherwahrnehmung und Bewertung gesundheitsfördernder Eigenschaften von Lebensmitteln motivierten diese Dissertation. Die Kontroversen umfassen die nicht eindeutige Verbindung zwischen Einkommensniveau und der Nachfrage nach funktionellen Lebensmitteln, umstrittenen Nutzen gesundheitsfördernder Eigenschaften für den Konsumenten und eine steigende Komplexität in Verbraucherentscheidungen. Ziel dieser Dissertation ist es, neue empirische Evidenz in Bezug auf Verbraucherwahrnehmung und Bewertung gesundheitsfördernden Eigenschaften von Lebensmitteln zu liefern, die Methodik zur Untersuchung von Verbraucherentscheidungen weiter zu entwickeln und die bestehenden Kenntnisse zusammenzufassen. Die Dissertation trägt zur bestehenden Literatur in den folgenden Punkte bei: (I) systematischer Review der Literatur mittels Metaanalyse; (II) Weiterentwicklung der Methodik für die Analyse empirischer Daten; (III) spezifische empirische Belege für eine bisher wenig untersuchte Region (Russland); und (IV) eine vergleichende Analyse qualitativer Daten in einem interkulturellen Kontext. | [
