description: Two-component regulatory systems composed of a membrane-bound sensor/sensory histidine kinase (HK) and a cytoplasmic, DNA-binding response regulator (RR) are often associated with transenvelope efflux systems, which export transition metal cations from the periplasm directly out of the cell. Although much work has been done in this field, more evidence is needed for the hypothesis that the respective two-component regulatory systems are indeed sensing periplasmic ions. If so, a regulatory circuit between the concentration of periplasmic metal cations, sensing of these metals, and control of expression of the genes for transenvelope efflux systems that remove periplasmic cations can be assumed. Escherichia coli possesses only one transenvelope efflux system for metal cations, the Cus system for export of Cu(I) and Ag(I). It is composed of the transenvelope efflux system CusCBA, the periplasmic copper chaperone CusF, and the two-component regulatory system CusS (HK) and CusR (RR). Using phoA- and lacZ-reporter gene fusions, it was verified that an assumed periplasmic part of CusS is located in the periplasm. CusS was more important for copper resistance in E. coli under anaerobic conditions than under aerobic conditions and in complex medium more than in mineral salts medium. Predicted copper-binding sites in the periplasmic part of CusS were identified that, individually, were not essential for copper resistance but were in combination. In summary, evidence was obtained that the two-component regulatory system CusSR that controls expression of cusF and cusCBA does indeed sense periplasmic copper ions.

description: It is a well-known fact that water bodies are crucial for human life, ecosystems and biodiversity. Therefore, they are subject to regulatory monitoring in terms of water quality. However, land-use intensification, such as open-cast mining activities, can have a direct impact on water quality. Unfortunately, in situ measurements of water quality parameters are spatially limited, costly and time-consuming, which is why we proposed a combination of hyperspectral data, in situ data and simple regression models in this study to estimate and thus monitor various water quality parameters. We focused on the variables of total iron, ferrous iron, ferric iron, sulphate and chlorophyll-a. Unlike other studies, we used a combination of airborne hyperspectral and RGB data to ensure a very high spatial resolution of the data. To investigate the potential of our approach, we conducted simultaneous in situ measurements and airborne hyperspectral/RGB aircraft campaigns at different sites of the Spree River in Germany to monitor the impact of pyrite weathering on water bodies after open-cast mining activities. Appropriate regression models were developed to estimate the five variables mentioned above. The model with the best performance for each variable gave a coefficient of determination R2 of 64% to 79%. This clearly shows the potential of airborne hyperspectral/RGB data for water quality monitoring. In further investigations, we focused on the use of machine learning techniques, as well as transferability to other water bodies. The approach presented here has great potential for the development of a monitoring method for the continuous monitoring of still waters and large watercourses, especially given the freely available space-based hyperspectral missions via EnMAP.

description: Background: Immediate delivery is an established concept for preventing life-threatening complications in mothers with HELLP syndrome; however, it is associated with preterm births. Methods: Cases of HELLP syndrome diagnosed at the university hospitals of Halle and Magdeburg (Germany) were analyzed retrospectively. Each patient of the treatment group was administered 64 mg of methylprednisolone (MP) intravenously for 10 days, with the dosage being reduced by 50% every other day in patients from Halle (n = 65). Almost immediate delivery was performed in the control groups (n = 45, Halle; n = 28, Magdeburg). Results: Pregnancies in the treatment group were prolonged by 4 days (median 1–55 days). The platelet counts increased from 76,060 ± 22,900/μL to 117,430 ± 39,065/μL in the MP group compared with an increase from 66,500 ± 25,852/μL to 83,430 ± 34,608/μL in control group 1 and from 78,890 ± 19,100/μL to 131,080 ± 50,900/µL in control group 2 (p < 0.001). Severe neonatal complications were significantly reduced in the treatment group (p < 0.05): sepsis, 9.25% vs. 24%; ventilation, 44.6% vs. 46.5%; and infant death, 1.6% vs. 8.6%. Conclusions: In a selected collective of patients with HELLP syndrome, prolongation of pregnancy using MP treatment improved maternal and neonatal outcomes.

description: Background: In the connected world, although societies are not directly involved in a military conflict, they are exposed to media reports of violence. Aims: We assessed the effects of such exposures on mental health in Germany during the military conflict in Ukraine. Method: We used the German population-based cohort for digital health research, DigiHero, launching a survey on the eighth day of the Russo-Ukrainian war. Of the 27 509 cohort participants from the general population, 19 444 (70.7%) responded within 17 days. We measured mental health and fear of the impact of war compared with other fears (natural disasters or health-related). Results: In a subsample of 4441 participants assessed twice, anxiety in the population (measured by the Generalised Anxiety Disorder-7 screener) was higher in the first weeks of war than during the strongest COVID-19 restrictions. Anxiety was elevated across the whole age spectrum, and the mean was above the cut-off for mild anxiety. Over 95% of participants expressed various degrees of fear of the impact of war, whereas the percentage for other investigated fears was 0.47–0.82. A one-point difference in the fear of the impact of war was associated with a 2.5 point (95% CI 2.42–2.58) increase in anxiety (11.9% of the maximum anxiety score). For emotional distress, the increase was 0.67 points (0.66–0.68) (16.75% of the maximum score). Conclusions: The population in Germany reacted to the Russo-Ukrainian war with substantial distress, exceeding reactions during the strongest restrictions in the COVID-19 pandemic. Fear of the impact of war was associated with worse mental health.
Non-equilibrium interfaces in colloidal fluids

description: The time-dependent structure, interfacial tension, and evaporation of an oversaturated colloid-rich (liquid) phase in contact with an undersaturated colloid-poor (vapor) phase of a colloidal dispersion is investigated theoretically during the early-stage relaxation, where the interface is relaxing towards a local equilibrium state while the bulk phases are still out of equilibrium. Since systems of this type exhibit a clear separation of colloidal and solvent relaxation time scales with typical times of interfacial tension measurements in between, they can be expected to be suitable for analogous experimental studies, too. The major finding is that, irrespective of how much the bulk phases differ from two-phase coexistence, the interfacial structure and the interfacial tension approach those at two-phase coexistence during the early-stage relaxation process. This is a surprising observation since it implies that the relaxation towards global equilibrium of the interface is not following but preceding that of the bulk phases. Scaling forms for the local chemical potential, the flux, and the dissipation rate exhibit qualitatively different leading order contributions depending on whether an equilibrium or a non-equilibrium system is considered. The degree of non-equilibrium between the bulk phases is found to not influence the qualitative relaxation behavior (i.e., the values of power-law exponents), but to determine the quantitative deviation of the observed quantities from their values at two-phase coexistence. Whereas the underlying dynamics differs between colloidal and molecular fluids, the behavior of quantities such as the interfacial tension approaching the equilibrium values during the early-stage relaxation process, during which non-equilibrium conditions of the bulk phases are not changed, can be expected to occur for both types of systems.

description: The previously undescribed natural product lumnitzeralactone (1), which represents a derivative of ellagic acid, was isolated from the anti-bacterial extract of the Indonesian mangrove species Lumnitzera racemosa Willd. The structure of lumnitzeralactone (1), a proton-deficient and highly challenging condensed aromatic ring system, was unambiguously elucidated by extensive spectroscopic analyses involving high-resolution mass spectrometry (HRMS), 1D 1H and 13C nuclear magnetic resonance spectroscopy (NMR), and 2D NMR (including 1,1-ADEQUATE and 1,n-ADEQUATE). Determination of the structure was supported by computer-assisted structure elucidation (CASE system applying ACD-SE), density functional theory (DFT) calculations, and a two-step chemical synthesis. Possible biosynthetic pathways involving mangrove-associated fungi have been suggested.

description: Soil microbial communities play crucial roles in the earth’s biogeochemical cycles. Yet, their genomic potential for nutrient cycling in association with tree mycorrhizal type and tree-tree interactions remained unclear, especially in diverse tree communities. Here, we studied the genomic potential of soil fungi and bacteria with arbuscular (AM) and ectomycorrhizal (EcM) conspecific tree species pairs (TSPs) at three tree diversity levels in a subtropical tree diversity experiment (BEF-China). The soil fungi and bacteria of the TSPs’ interaction zone were characterized by amplicon sequencing, and their subcommunities were determined using a microbial interkingdom co-occurrence network approach. Their potential genomic functions were predicted with regard to the three major nutrients carbon (C), nitrogen (N), and phosphorus (P) and their combinations. We found the microbial subcommunities that were significantly responding to different soil characteristics. The tree mycorrhizal type significantly influenced the functional composition of these co-occurring subcommunities in monospecific stands and two-tree-species mixtures but not in mixtures with more than three tree species (here multi-tree-species mixtures). Differentiation of subcommunities was driven by differentially abundant taxa producing different sets of nutrient cycling enzymes across the tree diversity levels, predominantly enzymes of the P (n = 11 and 16) cycles, followed by the N (n = 9) and C (n = 9) cycles, in monospecific stands and two-tree-species mixtures, respectively. Fungi of the Agaricomycetes, Sordariomycetes, Eurotiomycetes, and Leotiomycetes and bacteria of the Verrucomicrobia, Acidobacteria, Alphaproteobacteria, and Actinobacteria were the major differential contributors (48% to 62%) to the nutrient cycling functional abundances of soil microbial communities across tree diversity levels. Our study demonstrated the versatility and significance of microbial subcommunities in different soil nutrient cycling processes of forest ecosystems.

title: The international politics and operational control of potentially dangerous technology: A case study of reconminant DNA
Creators: name: Russell, Alan Myles
Publisher: name: University of Kent
Year: 2023

description: The focus of this thesis is on the international features of the case of recombinant DNA. A transnational model of decision-making is applied to the development and implementation of safeguards which followed the authoritative public announcement by eleven leading microbiologists that certain new experimental techniques involved conjectured hazards. The case is taken, in an historical context, as an example of a new technology displaying 'low probability, high consequence' risks emphasising the international uncertainty involved. A multi-levelled systems approach is adopted to link organisational decision-making analysis to concepts of transnational political relationships (developed from K. Deutsch, R. Keohane and J. Nye, J. Burton, H. Simon, R. Cyert and J. March, W. Evans, and G.T. Allison). The study stresses the importance of operational safeguards developed in the United States and the United Kingdom, illustrating their roles as models, often borrowed and modified elsewhere. In all, some thirty-two states and eleven international organisations are covered, emphasising communications linkages and sources of information. Uncertainty concerning potential hazards led to a transnational incremental approach to the process of decision-making as it affected the development and operationalisation of control options designed to reduce risk. Satisfactory rather than optimal strategies resulted. It was apparent that the limitations faced in 'rational' assessments assisted the growth of political debate in an overall climate of empirical uncertainty. Scientists proved to be well organised internationally, and on the whole retained a dominant input into the transnational decision-making, despite the general level of political controversy. The case stands as an object lesson in the problems associated with internationally assessing uncertain hazards (and benefits) despite the presently accepted perception that risks are somewhat less than originally conceived.
title: Kontrolle des österreichischen Parlaments im Rahmen von Untersuchungsausschüssen
Creators: name: Lichtscheidl, Gelu
Year: 2023

description: Diese Masterarbeit versucht, eine möglichst umfangreiche Antwort darauf zu geben, wie die novellierte Verfahrensordnung über die Einsetzung von Untersuchungsausschüssen des österreichischen Nationalrats die „Opposition“ stärken konnte und wie diese im Rahmen des Unterrichts im Fach Geschichte und Politische Bildung zu kontextualisieren wäre. Im Bezug auf die novellierte Verfahrensordnung kann festgestellt werden, dass zwar im rechtlichen Sinne die „Opposition“ gestärkt wurde, aber aufgrund des realpolitischen Machtungleichgewichts, das bereits im Nationalrat herrscht, nicht in dem Ausmaß, wie es möglich gewesen wäre. Die „Opposition“ kann einen Untersuchungsausschuss nun leichter installieren, ihr realpolitischer Handlungsspielraum bleibt aber aufgrund der rechtlichen Vorgaben der Verfahrensordnung z.B. hinsichtlich der Befugnisse des Vorsitzes oder der Verfahrensdauer sehr stark begrenzt. Wie die Problematik dieses Machtungleichgewichtes in Unterrichtsmaterialien dargestellt wird, wurde anhand von sechs verschiedenen Schulbüchern untersucht. Im Rahmen der Analyse wurde festgestellt, dass fast alle Bücher diese Thematik kaum bis gar nicht behandeln. Es konnten sogar grobe Mängel und inhaltliche Fehler festgestellt werden. Daher hat es sich diese Masterarbeit zur Aufgabe gemacht, zu einem besseren Verständnis dieses Themas beizutragen. Dazu wurden sieben Unterrichtseinheiten (inklusive Unterrichtsmaterialien) ausgearbeitet.
description: This masterʼs thesis attempts to give an answer to how the amended rules of procedure on the appointment of congressional investigation committees of the Austrian National Council could strengthen the "opposition" and how this should be contextualized in the context of teaching history and political education. Concerning the amended rules of procedure, it can be stated that the "opposition" was strengthened in the legal sense, but not to the extent that would have been possible due to the real political power imbalance that already prevails in the National Council. The "opposition“ can now install a congressional investigation committee more easily, but their real political options remain very limited due to the legal requirements of the rules of procedure, e.g. regarding the powers of the chairperson or the duration of the procedure. How the problem of this power imbalance is presented in teaching materials was examined using six different textbooks. As part of the analysis, it was found that almost all books hardly or not at all deal with this topic. It was even possible to identify gross deficiencies and errors in the content. Therefore, this masterʼs thesis has set itself the task of contributing to a better understanding of this topic. For this purpose, six teaching units (including teaching materials) were developed.
title: Modifizierung von HSA-Nanopartikeln mit den Liganden Folsäure und Biotin und die Auswirkung auf die Bindung an Tumorzellen
Creators: name: Saibel, Walter
Year: 2023

description: Das Ziel der vorliegenden Arbeit war es, die in der Arbeitsgruppe entwickelten HSA-Nanopartikel mit Folsäure und Biotin zu modifizieren. Hierdurch sollte ein Drugtargeting-Effekt erreicht werden. Die beiden Vitamine wurden hierfür mittels DCC/NHS in einen Aktivester überführt und mit den HSA-Nanopartikeln gekoppelt. Anschließend wurden die erhaltenen Partikel bezüglich ihrer Größe, PDI, Zetapotentials, der Menge an gekoppelten Liganden und der freien Aminogruppen charakterisiert. Hierbei stellte sich heraus, dass Partikel, die mit 10 mg Folsäure-/Biotin-NHS / 0,5 mg Protein hergestellt wurden, die besten Resultate hinsichtlich ihrer Partikeleigenschaften zeigten und auch ökonomisch am günstigsten waren. Es wurden Zellversuche am Monolayer, mittels CellCubes und am FACS mit KB- und MCF-7 Zellen durchgeführt. Diese Zellversuche zeigten eine Überlegenheit der modifizierten HSA-Nanopartikel in der Menge an internalisierten und an die Zellhülle gebundenen Partikel im Vergleich mit nicht-modifizierten HSA-Nanopartikel. Durch Kompetitionsstudien konnte auch gezeigt werden, dass dieser Effekt bei Folsäure-modifizierten HSA-Nanopartikeln auf die gebundene Folsäure zurückzuführen ist. Kolokalisationsstudien bei 4 °C zeigten eine Überlegenheit von modifizierten zu nicht-modifizierten Partikeln.
description: The following master’s thesis had the goal of developing an approach to modify HSA-nanoparticles, which were developed in our group, with folic acid and biotin. The hypothesis was, that this modification should result in a drug targeting effect. Both vitamins were transformed into an NHS active ester via DCC/NHS and thereafter coupled with the HSAnanoparticles. The resulting particles were characterized by size, PDI, zeta potential, the amount of coupled ligand and the amount of free amino acids in the hull. Particles which were prepared with an amount of 10 mg FA-NHS/ 0,5 mg protein showed the best results in their physical properties, and they were also the most economical ones. Cell studies with KB- and MCF-7 cells on monolayers, CellCubes and FACS were performed. The modified particles showed a superiority to the unmodified particles regarding internalisation and the number of particles binding to the cell hull. It was shown via competition studies, that the better performance from folic acid modified HSA-nanoparticles was reached solely via the folic acid. Colocalization studies at 4 °C showed a superiority of modified to unmodified HSA nanoparticles.

description: The Littlest Higgs model with T-parity is providing an attractive solution to the fine-tuning problem. This solution is only entirely natural if its intrinsic symmetry breaking scale f is relatively close to the electroweak scale. We examine the constraints using the latest results from the 8 TeV run at the LHC. Both direct searches and Higgs precision physics are taken into account. The constraints from Higgs couplings are by now competing with electroweak precision tests and both combined exclude f up to 694 GeV or 560 GeV depending on the implementation of the down-type Yukawa sector. Direct searches provide robust and complementary limits and constrain f to be larger than 638 GeV. We show that the Littlest Higgs model parameter space is slowly driven into the TeV range. Furthermore, we develop a strategy on how to optimise present supersymmetry searches for the considered model, with the goal to improve the constraints and yield more stringent limits on f.

description: The quickest change detection problem is considered in the context of monitoring large-scale independent normal distributed data streams with possible changes in some of the means. It is assumed that for each individual local data stream, either there are no local changes, or there is a "big" local change that is larger than a pre-specified lower bound. Two different kinds of scenarios are studied: one is the sparse post-change case when the unknown number of affected data streams is much smaller than the total number of data streams, and the other is when all local data streams are affected simultaneously although not necessarily identically. We propose a systematic approach to develop efficient global monitoring schemes for quickest change detection by combining hard thresholding with linear shrinkage estimators to estimating all post-change parameters simultaneously. Our theoretical analysis demonstrates that the shrinkage estimation can balance the tradeoff between the first-order and second-order terms of the asymptotic expression on the detection delays, and our numerical simulation studies illustrate the usefulness of shrinkage estimation and the challenge of Monte Carlo simulation of the average run length to false alarm in the context of online monitoring large-scale data streams.

description: Die im Stadtarchiv Krems in der Serie der Testamentsprotokolle überlieferten letztwilligen Verfügungen aus Stein an der Donau zwischen 1525 und 1627 wurden als Quelle zur Untersuchung der konfessionellen Zugehörigkeit in dieser niederösterreichischen Kleinstadt herangezogen. Anhand der enthaltenen frommen Legate sowie der verwendeten Formulierungen kann von Beginn der Konfessionalisierung um 1530, dem zunehmenden Übergang der Steiner Bevölkerung zum Protestantismus um 1560, der protestantischen Zeit Steins bis zum Ende des 16. Jahrhunderts bis hin zur Rückkehr zum Katholizismus nach 1600 die in der bisherigen einschlägigen Literatur dargestellte Entwicklung differenziert und verdichtet werden. Dabei werden sowohl Einzelbeispiele als auch allgemeine, teils gruppenspezifische Entwicklungen herausgearbeitet. Die über ein Jahrhundert abdeckende Analyse ermöglicht es, verschiedene Testierpraktiken zu unterscheiden und auf diese Weise sowohl Kontinuitäten als auch Veränderungen in der religiösen Praxis zu erkunden: Sowohl diese Untersuchungen als auch die Heranziehung von bisher unberücksichtigten Quellen stellen weitere Bausteine für eine Geschichte Steins im Rahmen des konfessionellen Zeitalters dar.
description: The last wills from Stein an der Donau between 1525 and 1627, preserved in the series of the so-called testamentary registers in the Krems Municipal Archives, are used as a source for investigating confessional affiliations in this small Lower Austrian town. The analysis of pious legacies mentioned in these wills as well as of the wording used allows for a more nuanced description of piety practices and confessional belonging than presented by previous research so far. My study covers the period from the beginning of the confessional age around 1530, the gradual transition of the population of Stein to Protestantism around 1560, the Protestant period of Stein until the end of the 16th century up to the gradual return to Catholicism after 1600. In this study, both individual examples are introduced and interpretations concerning more general developments of religious belonging, are presented. This analysis, which covers the time span of a century, allows for distinguishing between different testamentary practices, partly influenced by the testator’s confession, and to depict both continuities and changes in piety practices. Both these analyses and the use of hitherto unconsidered sources represent new elements for a more comprehensive history of Stein in the context of the confessional age.

Various cases corresponding to the electric charge and the angular momentum of the particles were considered. The studies were done for the general black hole as well as for the extreme black hole. There were two scenarios where the center-of-mass energy reach very large values if the appropriate properties of the particles are chosen.

description: We study the supercritical instability in gapped graphene with two charged impurities separated by distance R using the two-dimensional Dirac equation for electron quasiparticles. Attention is paid to a situation when charges of impurities are subcritical, whereas their total charge exceeds a critical one. The critical distance R_{cr} in the system of two charged centers is defined as that at which the electron bound state with the lowest energy reaches the boundary of the lower continuum. A variational calculation of the critical distance R_{cr} separating the supercritical (RR_{cr}) regimes is carried out. It is shown that the critical distance R_{cr} increases as the quasiparticle gap decreases. The energy and width of a quasistationary state as functions of the distance between two impurities are derived in the quasiclassical approximation.

title: "Wer die Jugend hat, hat die Zukunft." - Entwicklung des mittleren und höheren Schulwesens und der Braindrain-Bewegung im Burgenland von 1921 bis heute
Creators: name: Lehner, Christina Maria
Year: 2023

description: Das burgenländische mittlere und höhere Schulwesen wurde durch die ehemalige Zugehörigkeit des nunmehr österreichischen Bundeslandes zu Ungarn und durch mannigfaltige Umbrüche geprägt. In den ersten Jahrzehnten des Burgenlandes erfolgten in den wenigen im territorialen Gebiet verbliebenen Schulen zuallererst Anpassungsversuche an das österreichische System. Da aber das ungarische Schulsystem mit den entsprechenden Lehrplänen, Lehrpersonen und vor allem der Unterrichtssprache noch weitgehend vorlag, führten diese zu langwierigen Umstellungsarbeiten. Zudem war das burgenländische System noch lange Zeit von der kirchlichen Trägerschaft und somit dem konfessionellen Schulwesen belegt. Infolgedessen kam es immer wieder zu Debatten zwischen der Kirche und den Vertreter:innen der sozialdemokratischen Partei (Stichwort: Ludwig Leser). Hinzu kamen in den folgenden Jahrzehnten Veränderungen aufgrund von zeithistorischen Ereignissen: Besonders einschneiden für die bildungspolitischen Entwicklungen waren die ideologischen Pläne und Erziehungsziele der Dollfuß-Schuschnigg-Diktatur und der Nationalsozialisten. Da die Machthaber dieser Zeiten stets ein eigenes Erziehungsideal vor Augen hatten, veränderten sie auch das Schulsystem im „vaterländischen“ bzw. „nationalsozialistischen“ Sinne. Aufgrund der Zerstörungen, die der Zweite Weltkrieg mit sich brachte, war auch die burgenländische Schullandschaft – sowohl in der Zielsetzung als auch in den Gebäuden und Schulmaterialien – zerstört. Die Wiederaufbaumaßnahmen beinhalteten neben wiederkehrenden Debatten auch neue Ideen und den Sprung zum heutigen Bildungswesen, welcher maßgeblich durch die neue Gesetzgebung von 1962 geschah. Ebenso trug die andauernde Schaffung von neuen Schulstandorten aller Schultypen seit 1921 zur Entwicklung des Bildungswesens bei. Dieser Ausbau, welcher in großem Ausmaß auch das berufsbildende Schulwesen betrifft, wurde vor allem auch aufgrund der steigenden Landflucht und der Braindrain-Bewegung forciert. Das desolate Schulwesen, die schlechte Arbeitsplatzsituation und die miserable Infrastruktur in der Nachkriegszeit zwangen viele Burgenländer:innen dazu zu pendeln und in weiterer Folge oftmals ganz abzuwandern. Bis heute wurde deshalb im Burgenland ein breites Angebot an mittleren und höheren Schulen geschaffen, welches zudem vielfach gleichzeitig berufsbildend ist.

description: We investigate evolutionary dynamics of two-strategy matrix games with zealots in finite populations. Zealots are assumed to take either strategy regardless of the fitness. When the strategy selected by the zealots is the same, the fixation of the strategy selected by the zealots is a trivial outcome. We study fixation time in this scenario. We show that the fixation time is divided into three main regimes, in one of which the fixation time is short, and in the other two the fixation time is exponentially long in terms of the population size. Different from the case without zealots, there is a threshold selection intensity below which the fixation is fast for an arbitrary payoff matrix. We illustrate our results with examples of various social dilemma games.

title: Geschlechtsspezifische Gewalt gegen Frauen
Creators: name: Hajiyeva, Khayala
Year: 2023

description: Trotz der Bemühungen der internationalen Gemeinschaft, der Gewalt gegen Frauen ein Ende zu setzen, handelt es sich nach wie vor um ein globales Problem, das Frauen aus verschiedenen Ländern und mit unterschiedlichem sozialem Status betrifft. Im Zusammenhang mit der erzwungenen Migration hat die Gewalt gegen Flüchtlinge, insbesondere gegen Frauen, immer mehr zugenommen. Es gibt sehr viele Faktoren, die zum Anstieg der Gewalt gegen Frauen in den Flüchtlingslagern beitragen. In dieser Forschungsarbeit wird versucht, den Begriff GBV verständlich zu machen, theoretische und methodische Ansätze für dieses Phänomen zu entwickeln und die Gründe zu definieren, warum und wie Frauen in Flüchtlingslagern mit dieser Gewalt konfrontiert werden. Dies erfolgt im Rahmen einer Fallstudie über syrische Flüchtlingsfrauen in der Türkei. Anhand einer ausführlichen Literaturübersicht und der Definition des Begriffs GBV gegen Frauen in Verbindung mit Intersektionalität, strukturellen Geschlechterungleichheiten, Menschenrechten von Frauen und politisch-ökonomischen Ansätzen wird ein pragmatischer Aufruf zur kritischen Analyse von Gewalt in Bezug auf das Geschlecht entwickelt und die Gewalt und Diskriminierung, der Flüchtlingsfrauen ausgesetzt sind, insbesondere jene syrischer Herkunft, die in der Türkei untergebracht sind, untersucht. Der endemische, universelle und vielschichtige Charakter von geschlechtsspezifischer Gewalt ist die Grundlage für diese Arbeit, die sich auf bereits existierende Forschungen zu diesem Thema stützt und auch eine neu durchgeführte Forschung auf der Grundlage von Interviews mit syrischen Flüchtlingsfrauen präsentiert, die das Verständnis dieses Thema weiter vertieft.

description: Curso impartido en la Universidad Pública de Navarra. Curso de formación PDI. Impartido del 4 al 9 de noviembre de 2022 bajo el título de “Aula Invertida Híbrida: Fundamentos y aplicación para la puesta en práctica en el ámbito universitario” La metodología de Aula Invertida, también denominada Flipped Classroom o Flip Teaching, se basa en dos fases: el alumnado toma la lección en casa (de forma online) y posteriormente realiza los deberes en clase (de forma presencial). La metodología de Aula Invertida Híbrida tiene las mismas fases, pero se pueden aplicar indistintamente de forma online o de forma presencial. Esta característica la hace idónea para aplicarla en formación presencial, online, mixta y dual. La sesión se impartirá siguiendo la metodología de Aula Invertida Híbrida, en este caso aplicada en su modalidad on-line. Hay dos tipos de actividades: asíncronas y síncronas. Las asíncronas simularán “la lección en casa” y las síncronas simularán “los deberes en clase”. Este curso, de 8 horas de duración, se impartió del 4 al 9 de Noviembre, en modalidad online a través de ZOOM atendiendo al siguiente cronograma: Viernes 4 de Noviembre de 2022. Realización de la primera actividad del curso (1 hora de trabajo asíncrono) Lunes 7 de Noviembre de 2022 de 16:00 a 19:00. Introducción y métodos. Planificación para la puesta en práctica (3 horas de trabajo síncrono por VC) Martes 8 de Noviembre de 2022. Realización de la segunda actividad del curso hora de trabajo asíncrono) Miércoles 9 de Noviembre de 2022 de 16:00 a 19:00. Discusión y conclusiones (3 horas de trabajo síncrono por VC) Se contó con el apoyo de un mapa de conceptos generado a partir del material aportado por el profesorado y se fue complementando con las distintas actividades cooperativas realizadas.

description: Le concept de qualité de vie au travail a fait l’objet de plusieurs recherches dans le monde. Cependant, peu de travaux sur ce concept ont été effectués dans notre contexte d’étude. L’objectif de cette recherche à caractère exploratoire est d’identifier des pratiques de QVT dans les PME au Cameroun. Comme d’autres chercheurs, nous nous sommes inspirés d’un modèle de QVT existant dans la littérature afin d’élaborer notre guide d’entretien. Nous avons effectué des entretiens avec dix managers et responsables RH et effectué une analyse de contenu. Les résultats ont permis d’identifier les pratiques relatives aux conditions de travail, à la politique d’intégration sociale, à la gestion des carrières, au développement des compétences, aux respects des droits des employés, à la politique de conciliation de vie professionnelle et de vie privée, à la pertinence sociale de la vie professionnelle et au système de récompense. Contrairement au modèle de Walton (1973), notre recherche a permis de dissocier l’environnement des conditions de travail. Ces résultats débouchent sur des implications managériales utiles pour l’amélioration de la qualité de vie au travail des employés dans les PME.

description: In this paper, we present two simple approaches for deriving anisotropic distribution functions for a wide range of spherical models. The first method involves multiplying and dividing a basic augmented density with polynomials in $r$ and constructing more complex augmented densities in the process, from which we obtain the double-power distribution functions. This procedure is applied to a specific case of the Veltmann models that is known to closely approximate the Navarro-Frenk-White (NFW) profile, and also to the Plummer and Hernquist profiles (in the appendix). The second part of the paper is concerned with obtaining hypervirial distribution functions, i.e. distribution functions that satisfy the local virial theorem, for several well-known models. In order to construct the hypervirial augmented densities and the corresponding distribution functions, we start with an appropriate ansatz for the former and proceed to determine the coefficients appearing in that ansatz by expanding the potential--density pair as a series, around $r=0$ and $r=\infty$. By doing so, we obtain hypervirial distribution functions, valid in these two limits, that can generate the potential--density pairs of these models to an arbitrarily high degree of accuracy. This procedure is explicitly carried out for the Hénon isochrone, Jaffe, Dehnen and NFW models and the accuracy of this procedure is established. Finally, we derive some universal properties for these hypervirial distribution functions, involving the asymptotic behaviour of the anisotropy parameter and its relation to the density slope in this regime. In particular, we show that the cusp slope--central anisotropy inequality is saturated.

description: Heterostructures of transition-metal oxides emerged as a new route to engineer electronic systems with desired functionalities. Motivated by these developments, we study a two-orbital Hubbard model in a thin-film geometry confined along the cubic [001] direction using the dynamical mean-field theory. We contrast the results of two approximate impurity solvers (exact diagonalization and one-crossing approximation) to the results of the numerically exact continuous-time quantum Monte Carlo solver. Consistent with earlier studies, we find that the one-crossing approximation performs well in the insulating regime, while the advantage of the exact-diagonalization based solver is more pronounced in the metallic regime. We then investigate various aspects of strongly correlated eg-orbital systems in thin film geometries. In particular, we show how the interfacial orbital polarization dies off quickly a few layers from the interface and how the film thickness affects the location of the interaction-driven Mott transition. In addition, we explore the changes in the electronic structure with varying carrier concentration and identify large variations of the orbital polarization in the strongly correlated regime.

title: Subjektive Wahrnehmung und Bedeutung der schulischen Gesundheitsförderung aus Sicht von SchülerInnen der Sekundarstufe II am Beispiel einer WieNGS-Schule
Creators: name: Weber, Franz
Year: 2023

description: Schaut man sich die Entwicklung des Gesundheitsverhaltens von Kindern und Jugendlichen an, so ist diese im Allgemeinen recht negativ zu bewerten. Da diese Altersgruppe einen Großteil ihrer Zeit in der Schule verbringt, nimmt Gesundheitsförderung im Setting Schule eine besonders wichtige Rolle ein. Es existieren zahlreiche Publikationen zu diesem Thema, die jedoch den Anschein erwecken, dass der Fokus gesundheitsfördernder Maßnahmen vor allem auf die jüngeren SchülerInnen der Primar- und Sekundarstufe I gerichtet ist. Daher hat es sich die Masterarbeit zur Aufgabe gemacht, die Wahrnehmung und Bewertung schulischer Gesundheitsförderung von SchülerInnen der Sekundarstufe II am Beispiel einer WieNGS-Schule zu untersuchen. Um die Forschungsfrage zu beantworten, wurde zunächst überwiegend deutschsprachige Literatur einer hermeneutischen Analyse unterzogen. Diese hat gezeigt, dass zwischen der Institution Schule und der Gesundheit von Kindern und Jugendlichen ein Zusammenhang besteht. Die Rahmenbedingungen der Schule können sich sowohl positiv als auch negativ auf die Gesundheit von SchülerInnen auswirken. Umso wichtiger erscheint eine effektive Gesundheitsförderung im Setting Schule. Die empirische Untersuchung zur subjektiven Wahrnehmung der Gesundheitsförderung von SchülerInnen der Sekundarstufe II hat gezeigt, dass es zwar viele gesundheitsfördernde Projekte, Programme und Maßnahmen gibt, die für alle Altersgruppen konzipiert wurden, jedoch vor allem die jüngeren SchülerInnen der Sekundarstufe I bedienen. Demnach sollten die Angebote entsprechend angepasst werden, um auch für OberstufenschülerInnen attraktiv zu werden. Ein besonderer Fokus sollte zudem auf die psychische Gesundheit gelegt werden. Des Weiteren zeigte sich, dass den SchülerInnen viele gesundheitsfördernde Angebote nicht bekannt sind. Hier besteht dringender Informations- und Aufklärungsbedarf. Dies gilt sowohl für Angebote im Bereich Bewegung und Ernährung, viel mehr jedoch noch hinsichtlich der Angebote für die psychische Gesundheit von SchülerInnen. Es wäre schade, wenn gesundheitsfördernde Maßnahmen nur deshalb nicht genutzt werden, weil die SchülerInnen nichts über deren Existenz wissen.
