title: Die Auswirkung negativer Berichterstattung zum Thema Klimawandel auf die mentale Gesundheit
Creators: name: Holzer, Marina
Year: 2023

description: Aktuell zählt die Klimakrise zu einem der wichtigsten Themen der öffentlichen Agenda und wurde von der WHO sogar als größte Bedrohung für die Gesundheit der Menschen eingestuft. Parallel dazu wurde es seit der von Covid-19 verursachten Pandemie zu einem gesamtgesellschaftlichen Auftrag, psychische Belastungen nicht nur zu reduzieren, sondern ihnen auch präventiv entgegenzuwirken. Da der Mensch durch die massenmediale Berichterstattung andauernd der Thematik des Klimawandels ausgesetzt ist und die entsprechenden Artikel beinahe durchwegs stark negativ und pessimistisch formuliert sind, ist das Ziel dieser Forschung zu untersuchen, inwieweit sich dies auf die mentale Gesundheit der Menschen und wiederum auf die Einschätzung des Klimawandels auswirkt. Dafür wurde ein quantitatives Online-Experiment durchgeführt, um mithilfe einer Post-Messung die aktuellen Wohlbefindens- und Depressivitätswerte, als auch die Einschätzung der Klimawandelthematik, nach dem Lesen eines stark negativ vs. eines stark positiv formulierten Artikels zu erforschen. Die Ergebnisse dieser Arbeit zeigen, dass das Lesen negativ formulierter Artikel zum Thema Klimawandel eine signifikant negative Auswirkung auf die mentale Gesundheit einer Person, in Anbetracht ihrer Depressivitäts- und Wohlbefindenswerte hat. Die Art des Artikels hat dabei jedoch keine signifikante Auswirkung auf die Einschätzung des Klimawandels als wichtig und bedrohlich. Dieses Ergebnis bringt somit neue Erkenntnisse für zukünftige Klimawandelberichterstattung.
description: The ongoing climate crisis is currently one of the most important topics and has even been classified as the greatest threat to human health by the WHO. At the same time, primarily since the pandemic caused by Covid-19, it has become a task for our society not only to reduce psychological stress, but also to counteract it preventively. Since people are constantly exposed to the topic of climate change through mass media reporting and the relevant articles are almost always formulated in a strongly negative and pessimistic manner, the aim of this research is to investigate to what extent this affects people's mental health and their assessment of climate change effects. For this purpose, a quantitative online experiment was carried out to research current well-being and depression levels, as well as the assessment of climate change issues, after reading a strongly negative vs. strongly positively worded article. The results of this work show that reading negatively worded articles about climate change has a significantly negative impact on a person's mental health, considering their depression and well-being scores. However, the type of article has no significant impact on the assessment of climate change as an important and threatening topic. This result brings new insights for future climate change reporting.

description: The aim of the research was to estimate the changes in profitability of production of pigs for slaughter. The analysis included data from GUS (Central Statistical Office) and IERiGŻ (Institute of Agricultural Economics and Food Economy), as well as information from farms in Wielkopolska province that produced hundred or more porkers yearly and conducted accountancy within the Polish FADN system in the 2004. The profitability of production of pigs for slaughter is influenced primarily by the purchase prices of pigs and fodder costs. Polish accession to the EU has not stopped changes in the conditions in the market of pork meat. During periods of adverse conditions most breeders do not undertake any actions, but some farmers prolong the feeding period or decrease the size of sow herds. In order to stabilize prices in the pig market the introduction of system solutions and new outlet markets are being sought. / Synopsis. Celem badań było określenie zmian w opłacalności produkcji żywca wieprzowego w Polsce po integracji z UE. W analizie wykorzystano dane GUS, IERiGŻ oraz informacje z gospodarstw w Wielkopolsce, które produkowały 100 i więcej tuczników rocznie oraz prowadziły rachunkowość w ramach polskiego FADN. Z badań wynika, że na opłacalność produkcji żywca wieprzowego wpływają głownie ceny skupu trzody chlewnej oraz koszty pasz. Przystąpienie Polski do UE nie zlikwidowało zmian koniunkturalnych na rynku wieprzowiny. W okresie dekoniunktury większość producentów żywca wieprzowego nie podejmuje żadnych działań, ale część rolników przedłuża okres tuczu albo zmniejsza stada loch. W celu stabilizacji cen na rynku trzody chlewnej dąży się do wprowadzenia rozwiązań systemowych i poszukuje się nowych rynków zbytu.

Cognitive dietary restraint and factors related to bone mineral density and body weight in postmenopausal women
Creators: name: Rideout, Candice AnnMarie
Publisher: name: University of British Columbia
Year: 2010

description: Cognitive dietary restraint (ongoing effort to limit dietary intake to manage body weight) is common in young women and has been associated with increased cortisol excretion and reduced bone mineral content (BMC). However, little is known about dietary restraint and its possible association with health in older women. This research addressed this gap by exploring cognitive dietary restraint in postmenopausal women aged 45-75 years. A broad survey of 1071 women assessed dietary restraint and other characteristics, and 78 respondents with high or low dietary restraint were recruited to complete measures of cortisol excretion, perceived stress, dietary intake, lifetime physical activity, and body composition. Study 1 examined cortisol excretion and body composition in women with high (n=41) versus low (n=37) dietary restraint. Groups were similar in age, body mass index (BMI), waist-to-hip ratio, current exercise, energy intake, perceived stress, body fat, BMC, and bone mineral density (BMD). However, cortisol excretion was higher in the high restraint group (248.2 ± 61.7 nmol/day versus 204.3 ± 66.1 nmol/day, P=0.01). Lifetime physical activity and current BMD were investigated in those participants in Study 2. Teenage physical activity, but not activity during other age periods, predicted postmenopausal BMD at both the lumbar spine (R²=0.110, P=0.004) and mean proximal femora (ΔR²=0.106, P=0.002). In Study 3, dietary restraint and ’dieting’ were compared in the 1071 survey respondents. Controlling for dietary restraint, dieters had higher BMI than non-dieters (+4.1 kg/m²; 95% CI: 3.6, 4.6). Conversely, controlling for dieting status, restrained eaters had lower BMI than unrestrained eaters (-1.0 kg/m²; 95% CI: -1.6, -0.5). Additional differences in food choice motives and psychosocial characteristics indicate that dietary restraint and dieting are not analogous. Finally, in Study 4, eating attitudes and weight-related characteristics were explored in survey respondents grouped according to 10-year weight history (maintenance, loss, gain, cycling). Disinhibition of eating control was the strongest predictor of current BMI in each weight history group, accounting for 11-20% of the variance. Dietary restraint predicted BMI only among women who had experienced weight cycling. Together, these studies suggest subtle differences in eating and activity characteristics contribute to the health of postmenopausal women.

description: Die vorliegende Arbeit geht der Frage nach, inwieweit sich Fälle von Münchhausen by Internet auf die Spendenbereitschaft von Personen ausüben können. Es soll folgende Forschungsfrage beantwortet werden: Welche Auswirkungen haben Fälle von Münchhausen by Internet auf die Spendenbereitschaft und könnte einer potenziellen Minderung dieser Spendenbereitschaft entgegengewirkt werden? Spenden, besonders solche, die online stattfinden, sind zu einem großen Ausmaß abhängig von dem Vertrauen, welches die potenziellen Spender*innen gegenüber den Personen sowie der Spendenplattform haben, die zu den Spenden aufrufen (Trust Transfer Theory). Fälle von Münchhausen by Internet haben einen negativen Einfluss auf das Vertrauen innerhalb der Online-Gruppen, in denen sich diese Fälle ereignen. Zur Beantwortung der Forschungsfrage wurde eine quantitative Umfrage durchgeführt, in welcher die Befragten in drei verschiedene Experimentalgruppen eingeteilt wurden. In der durchgeführten Studie konnte kein Einfluss von Münchhausen by Internet Fällen auf die Spendenbereitschaft von Individuen festgestellt werden.
description: The present study explores the extent to which cases of Munchhausen by Internet can influence individuals’ willingness to donate. Donations, especially those conducted online, are heavily reliant on the trust that potential donors have in the individual appealing for donations and into the platform on which they are asking for those donations (Trust Transfer Theory). Cases of Munchausen by Internet have a negative impact on trust within the online group where these cases occur. To answer the research question, a quantitative survey was conducted. In this survey respondents were divided into three different experimental groups. I the conducted study no influence of Munchhausen by Internet cases on individuals’ willingness to donate could be observed.

description: In the envelope-function approximation, interband transitions produced by electric fields are neglected. However, electric fields may lead to a spatially local ($k$-independent) coupling of band (internal, pseudospin) degrees of freedom. Such a coupling exists between heavy-hole and light-hole (pseudo-)spin states for holes in III-V semiconductors, such as GaAs, or in group IV semiconductors (germanium, silicon, ...) with broken inversion symmetry. Here, we calculate the electric-dipole (pseudospin-electric) coupling for holes in GaAs from first principles. We find a transition dipole of $0.5$ debye, a significant fraction of that for the hydrogen-atom $1s\to2p$ transition. In addition, we derive the Dresselhaus spin-orbit coupling that is generated by this transition dipole for heavy holes in a triangular quantum well. A quantitative microscopic description of this pseudospin-electric coupling may be important for understanding the origin of spin splitting in quantum wells, spin coherence/relaxation ($T_2^*/T_1$) times, spin-electric coupling for cavity-QED, electric-dipole spin resonance, and spin non-conserving tunneling in double quantum dot systems.

description: Die vorliegende Diplomarbeit befasst sich mit der Ermittlung von Anpassungsfaktoren zur vereinfachten Erfassung der Fahrzeug-Brücke-Interaktion bei Brückentragwerken unter Hochgeschwindigkeitszugverkehr. Im Rahmen der Diplomarbeit wird eine Parameterstudie durchgeführt, um die Differenz der Tragwerksantwort zwischen der Belastung durch Einzelkräfte und der Belastung durch ein realitätsnahes Zugmodell (Mehrkörpermodell) festzustellen. Auf Basis der Ergebnisse der Parameterstudie werden für die untersuchten Brückentragwerke die Anpassungsfaktoren berechnet, welche eine Adaptierung der Ergebnisse eines Modells mit Einzelkräften ermöglichen, sodass diese die Ergebnisse eines realitätsnäheren Zugmodells approximieren können. Bei der Kontrolle der Funktionstüchtigkeit werden zwei Möglichkeiten für die Anpassung der Systemantwort untersucht: eine Anpassung innerhalb einer bestimmten Spannweite L und eine Anpassung zwischen unterschiedlichen Spannweiten L. Zum Schluss werden die Formeln zur Abschätzung der Anpassungsfaktoren hergeleitet, welche eine Anwendung in der Praxis vereinfachen sollen.
description: This master thesis is concerned with the determination of adjustment factors for simplified consideration of the train-bridge interaction for the high-speed railway bridges. As part of the thesis, a parametric study is performed with the purpose to determine the difference in the structural response between the travelling loads model and the detailed multi-body model. Based on the results of the parametric study, the adjustment factors for examined bridges are calculated. The adjustment factors allow a correction of the results of travelling loads model, so these approximate the results of a detailed multi-body train model. There were studied two possibilities for customization of the system response: an adjustment within a certain span L and an adjustment between different spans L. Finally, the formulas for estimating the adjustment factors were derived, which are designed to simplify an application in practice.
The BB84 quantum key distribution using conjugate homodyne detection

Subjects: subject: Quantum Physics (quant-ph)

description: Optical homodyne detection has been widely used in continuous-variable (CV) quantum information processing for measuring field quadrature values. In this paper we explore the possibility of operating a conjugate homodyne detection system in "photon counting" mode to implement discrete-variable (DV) quantum key distribution (QKD) protocols. A conjugate homodyne detection system, which consists of a beam splitter followed by two optical homodyne detectors, can simultaneously measure a pair of conjugate quadratures X and P of the incoming quantum state. In classical electrodynamics, X^2 + P^2 is proportional to the energy (the photon number) of the input light. In quantum optics, X and P do not commute and thus the above photon-number measurement is intrinsically noisy. This suggests that a blind application of the standard security proof could result pessimistic QKD performance. We overcome this obstacle by taking advantage of two special features of the proposed detection scheme. First, the fundamental detection noise associated with vacuum fluctuation cannot be manipulated by an external adversary. Second, the ability to reconstruct the photon number statistics at the receiver's end can place additional constraints on possible attacks from the adversary. As an example, we study the security of the BB84 QKD using conjugate homodyne detection and evaluate its performance through numerical simulations. This study may open the door to a new family of QKD protocols, in complementary to the well-established DV-QKD based on single photon detection and CV-QKD based on coherent detection.

description: This article offers an overview of farmers’ evaluation of governmental institutions in Poland serving agriculture (Ministry of Agriculture and Rural Development, Agency for Restructuring and Modernisation of Agriculture and Agricultural Market Agency) as well as points out to possible changes and improvements in their activities. A cross-country survey of 200 individual farm managers taking advantage of services provided by both agencies was conducted in 2006. In farmers’ opinion those institutions generally do not differ in quality of provided services from other governmental bodies, both have an impact on the economic and financial situation of their farms and both are inadequately managing public money. The agencies did not make improvements in administration of farm programs but they are perceived by respondents as representing mainly Polish farmers’ interests. / Synopis.

Badanie ankietowe przeprowadzono w 2006 r. na ogólnopolskiej próbie 200 kierowników indywidualnych gospodarstw rolnych korzystających z usług obu agencji. W opinii rolników na ogół instytucje te nie różnią się od innych urzędów państwowych pod względem jakości świadczonych usług, mają wpływ na sytuację ekonomiczno- finansową ich gospodarstw, niedostatecznie gospodarują środkami publicznymi. W zasadzie nie nastąpiła poprawa w administrowaniu przez agencje programami na rzecz rolnictwa, ale są postrzegane przez rolników jako reprezentujące głównie ich interesy.

description: We experimentally studied the Rydberg level shift caused by the electric field, which is generated by Rydberg atom collision induced ionization in a cesium atomic ensemble. The density of charged particles caused by collisions between Rydberg atoms is changed by controlling the ground-state atomic density and optical excitation process. We measured the Rydberg level shift using Rydberg electromagnetically-induced-transparency (EIT) spectroscopy, and interpreted the physical origin using a semi-classical model. The experimental results are in good agreement with the numerical simulation. These energy shifts are important for the self-calibrated sensing of microwave field by the employing of Rydberg EIT. Moreover, in contrast to the resonant excitation case, narrow-linewidth spectroscopy with high signal-to-noise ratio would be useful for high-precision measurements.

description: The exact entropy of two-charge supersymmetric black holes in N=4 string theories is computed to all orders using Wald's formula and the supersymmetric attractor equations with an effective action that includes the relevant higher curvature terms. Classically, these black holes have zero area but the attractor equations are still applicable at the quantum level. The quantum corrected macroscopic entropy agrees precisely with the microscopic counting for an infinite tower of fundamental string states to all orders in an asymptotic expansion.

description: Homomorphic Encryption (HE) draws a significant attention as a privacy-preserving way for cloud computing because it allows computation on encrypted messages called ciphertexts. Among numerous HE schemes proposed, HE for Arithmetic of Approximate Numbers (HEAAN) is rapidly gaining popularity across a wide range of applications because it supports messages that can tolerate approximate computation with no limit on the number of arithmetic operations applicable to the corresponding ciphertexts. A critical shortcoming of HE is the high computation complexity of ciphertext arithmetic; especially, HE multiplication (HE Mul) is more than 10,000 times slower than the corresponding multiplication between unencrypted messages. This leads to a large body of HE acceleration studies, including ones exploiting FPGAs; however, those did not conduct a rigorous analysis of computational complexity and data access patterns of HE Mul. Moreover, the proposals mostly focused on designs with small parameter sizes, making it difficult to accurately estimate their performance in conducting a series of complex arithmetic operations. In this paper, we first describe how HE Mul of HEAAN is performed in a manner friendly to computer architects. Then we conduct a disciplined analysis on its computational and memory access characteristics, through which we (1) extract parallelism in the key functions composing HE Mul and (2) demonstrate how to effectively map the parallelism to the popular parallel processing platforms, multicore CPUs and GPUs, by applying a series of optimization techniques such as transposing matrices and pinning data to threads. This leads to the performance improvement of HE Mul on a CPU and a GPU by 42.9x and 134.1x, respectively, over the single-thread reference HEAAN running on a CPU. The conducted analysis and optimization would set a new foundation for future HE acceleration research.
title: The employment, development and support of part-time lecturers in one UK university
Creators: name: Marshall, Sarah
Publisher: name: The Open University
Year: 2004

description: This research explored the nature and extent of the contribution of part-time lecturers to student learning in Higher Education, through a case study of one UK University. It drew on the experiences and opinions of part-time lecturers themselves, and of course directors, who had direct responsibility for managing the courses on which the part-timers taught. The primary data for the study was collected through a survey of each of these two groups of staff, covering the academic year 2000-2001. While the survey data in this study were largely quantitative, the inclusion of open questions provided opportunities for staff to express their own views. The issues raised were analysed against the background of previous research and emerging policy and legislation. The overall picture that emerged was of a group of staff who were enthusiastic and knowledgeable about their subject areas and committed to teaching students.However, their enthusiasm was tempered in many cases by the general failure of the university to manage this very important human resource strategically or effectively. There were examples in the responses of poor communication with part-time staff, poor administration, especially in relation to contracts and payment, lack of consideration of the information and resource needs of part-time lecturers, limited training and development opportunities, high levels of uncertainty and a tendency for managers to view part-time lecturers as a `flexible commodity'. Course directors frequently referred to the additional administration and student support that full-time academics had to take on because of the nature of the contracts given to most part-time lecturers. While there were a few examples of part-time lecturers who were well-integrated and expressed a sense of belonging to the faculty and the organisation, there were many who felt isolated and marginalised: they were rarely included in decision-making processes received only such information as directly related to the module(s) they were teaching, rarely communicated with students outside the lecture theatre or classroom and, when they did undertake broader roles (which many did), were rarely paid for the additional work. Some recommendations are made for a more strategic and inclusive approach to the management of part-time lecturers, which it is believed would have benefits for part-time and full-time lecturers alike, and would also enhance the quality of the student experience. Suggestions are also made for future research and development, including an exploration of the potential for web-based communication to reduce isolation.
Ambleside : better living by the water

description: The Ambleside waterfront, District of West Vancouver, has the potential to act as the armature for a water-borne transit link from this established neighborhood to the Central Business District (C.B.D.) of Vancouver. By in-filling the under-used spaces and redeveloping several existing sites, the optimum employment of this historically ferry-serviced waterfront may once again come to the fore. As every transit trip begins with a pedestrian event, a key component of this project is re-establishing and enhancing the pedestrian connections through the commercial/residential centre and along the linear shore park. Using and studying how, the principles of Transit Oriented Development (T.O.D.) fit in with the Ambleside context and safety of the pedestrian realm by resolving conflicts between transit facilities will be appropriate to the site and sufficient in scale to accommodate the passenger loads. Care will also be made towards the enhancement of the site’s ecological functioning. This project is about the planning and design for more livable and complete communities. The results of policy review and site analysis will be elaborated through design. It is hoped that the finding will be applicable to similar transit nodes and waterfronts.

description: The current outbreak of the coronavirus disease 2019 (COVID-19) is an unprecedented example of how fast an infectious disease can spread around the globe (especially in urban areas) and the enormous impact it causes on public health and socio-economic activities. Despite the recent surge of investigations about different aspects of the COVID-19 pandemic, we still know little about the effects of city size on the propagation of this disease in urban areas. Here we investigate how the number of cases and deaths by COVID-19 scale with the population of Brazilian cities. Our results indicate small towns are proportionally more affected by COVID-19 during the initial spread of the disease, such that the cumulative numbers of cases and deaths per capita initially decrease with population size. However, during the long-term course of the pandemic, this urban advantage vanishes and large cities start to exhibit higher incidence of cases and deaths, such that every 1% rise in population is associated with a 0.14% increase in the number of fatalities per capita after about four months since the first two daily deaths. We argue that these patterns may be related to the existence of proportionally more health infrastructure in the largest cities and a lower proportion of older adults in large urban areas. We also find the initial growth rate of cases and deaths to be higher in large cities; however, these growth rates tend to decrease in large cities and to increase in small ones over time.

Al calcular estas mismas correlaciones para el grupo de la raza holstain obtuvimos r = 0.66, 0.66, 0.75 y 0.71 (P < 0.01). Coeficientes de corrrelación desde moderados hasta altos encontramos entre el espesor del músculo glúteo superficial de la pierna derecha y todos los indicadores de la composición de la canal aqui analizados r = 0.57 - 0.73, (P < 0.05, 0.01). Al correlacionar las mediciones ecográficas de la región del músculo infraspinato, 13ava vertebra torácica y 5ta vertebra lumbal con los indicadores de la composición de la canal encontramos coeficientes moderados o no significativos. La capacidad de predicción de las ecuaciones de regresión lineal del peso de la canal caliente, peso de la canal oreada y peso de los cortes de primera vario sustancialmente. Donde se incluyó el peso vivo antes del sacrificio fué superior (R2 = 0.96, 0.95 y 0.87), en el caso donde se excluyó fué inferior (R2 = 0.74, 0.74 y 0.47). Los resultados obtenidos alientan su utilización como técnica predictoria de la composición de la canal bovina.

description: There have been a number of observations of infrared (IR) echoes associated with tidal disruption events (TDEs). These arise as a result of re-radiation of the TDE’s UV/optical photons by dust in the nuclear environment. Furthermore, there have been multiple fortuitous discoveries of IR echoes in the nuclei of luminous infrared galaxies (LIRGs) over the last few years, which have been identified as TDE candidates. LIRGs are dusty systems often resulting from galaxy mergers and hosting both a powerful starburst and an active galactic nucleus (AGN). TDE candidates in the dusty nuclei of LIRGs are challenging to identify and can often be out of the reach of optical or X-ray observations due to the large column densities of gas and dust obscuring them. Therefore, IR observations are required to characterise them, and can provide important information on the population of TDEs and their rates in these dust obscured nuclear environments. Additionally, IR echoes can be used to probe the total radiated energies from TDEs in cases where a significant fraction of the radiated energy was re-processed by dust to IR wavelengths.

 Here we present our search for nuclear transients within local LIRGs using mid-IR observations performed by the WISE satellite, which are almost unaffected by dust extinction. In this search we found multiple new TDE candidates through detection of luminous and slowly evolving mid-IR outbursts. We characterise the nature of these objects through modelling of the spectral energy distributions of their host galaxies and measurements of their luminosities and resulting energetics as well as by comparison of these properties with those of previously published TDEs and TDE candidates. Combining previous discoveries with the new transients detected as part of this search, we set a new lower limit for the rate of dust obscured TDEs occurring within LIRGs. We discuss the potential of ground-bases IR observations for such studies using the current and future facilities.

description: E n Nicaragua son pocos los estudios dedicados a investigar la enseñanza de la historia, lo que es sumamente preocupante porque sólo a través de la investigación se puede descender a las prácticas de la enseñanza de la historia para analizarlas, comprenderlas y mejorarlas. El objetivo de esta investigación, consiste en evaluar el aprendizaje de la historia iberoamericana en la educación secundaria. La importancia de la enseñanza de la historia iberoamericana ha sido agenda de discusión de la Organización de los Estados Iberoamericanos para la Educación, la Ciencia y la Cultura (OEI) desde los años 90 del siglo pasado resultando en la creación de la Cátedra de Historia de Iberoamerica. El presente trabajo es una investigación explorativa, con enfoque cuantitativo basada en la aplicación de 469 encuestas a estudiantes de la secundaria de 14 colegios en 8 departamentos del país. Las preguntas del cuestionario se refieren a los conocimientos, las percepciones y las valoraciones de los estudiantes respecto a la historia iberoamericana. Los resultados revelan que la mayoría de los estudiantes tienen graves deficiencias en cuanto a los conocimientos sobre el pasado de su propio país y los demás países iberoamericanos. Respecto a las representaciones se nota que otorgan mucha importancia al actuar de personalidades como Colón, San Martín y Bolívar. Además se observa que ven como causa principal de la existencia de una historia común de los países latinoamericanos el antiimperialismo y la revalorización de la herencia indígena.

description: The study covered the period 2004-2012, using as the research units 867 average farms representing 116 regions divided into the old and the new ones, according to whether the country to which they belong was a member of the EU before or after 2004. The research was based on the data from the European FADN system, looking for an answer to the question whether after the enlargement of the EU the structure of farms has been improved by increasing the specialization level and whether this process is more intensive in farms from the new regions compared to the farms from old ones. The results show a clear decrease of labor in units from new regions, faster than in units from old ones. In addition there are signs of progressive specialization, but also a significant increase of production value in units from the old regions, in the absence of a clear trend in units from the new regions. / Synopsis. W przeprowadzonym badaniu, obejmującym okres 2004-2012, za obiekty badawcze przyjęto 867 przeciętne gospodarstwa reprezentujące 116 regionów podzielonych na stare i nowe, w zależności w tego czy kraj macierzysty był członkiem UE przed czy dopiero po roku 2004. Badania oparto na danych pochodzących z europejskiego systemu FADN. W pracy podjęto próbę odpowiedzi na pytanie: czy po rozszerzeniu UE nastąpiła poprawa struktury gospodarstw rolnych poprzez większą ich specjalizację oraz czy ten proces jest bardziej intensywny w gospodarstwach z nowych regionów w porównaniu z gospodarstwami z regionów starych. Uzyskane wyniki wskazują na wyraźny spadek nakładów pracy w gospodarstwach z regionów nowych, szybszy niż w gospodarstwach z regionów starych. Ponadto odnotowano oznaki postępującej specjalizacji, ale też wyraźny wzrost wielkości produkcji w gospodarstwach z regionów starych, przy braku jasnej tendencji w regionach nowych.
title: Österreichische Erinnerungskultur als "Battleground"
Creators: name: Langreiter, Valentina
Year: 2023

description: In der hier vorliegenden Masterarbeit wurde untersucht, wie die öffentliche und veröffentlichte Meinung bezüglich der Opferthese und die nationalsozialistische Vergangenheit von Österreicher:innen die österreichische Identität und Erinnerungskultur einige Jahrzehnte prägte. Als theoretische Grundlagen dienten dazu die Forschung im Bereich ‚Erinnerungskultur‘ und ‚kollektives Gedächtnis‘ und Arbeiten aus dem Feld der österreichischen ‚Erinnerungskultur- und Opfermythosforschung‘. Im Zuge der methodischen Herangehensweise orientierte sich diese Arbeit an der Qualitativen Inhaltsanalyse nach Mayring (2010). Ausgehend von den theoretischen Grundlagen konnten sechs Phasen des Erinnerns identifiziert werden, welche als Analyseraster die Grundlage für die empirische Forschung dieser Masterarbeit bildeten. Es wurde untersucht, inwiefern sich diese Erinnerungsphasen in ausgewählten österreichischen Schulbüchern für Geschichte und Politische Bildung (GPB) seit 1960 widerspiegelten. Bezugnehmend auf die Forschungsergebnisse des empirischen Teils kommt diese Masterarbeit zu dem Schluss, dass erst die untersuchten GPB-Bücher aus 2018/2019 einen klaren Sprung hin zu einer kritischen Reflexion der Opferthese und österreichischer Erinnerungskultur darstellen.
description: This master’s thesis investigates how Austria’s post-war identity and remembrance culture was shaped and affected by public and published opinion regarding the Austrian “victim thesis” (‘Opferthese’) over a certain period of time. In order to do so, this thesis draws on the work of Assmann (2018) on collective memory and Erll’s (2005) research in the field of remembrance culture. Further, the most recent insights into the development of the Austrian victim thesis, remembrance culture and identity are presented. Mayring’s (2010) qualitative content analysis serves as basis for the empirical research. Based on this thesis’ theoretical research, six periods of remembering are identified. These periods of remembering are the foundation for the analysis grid used to examine six Austrian history schoolbooks between 1969 and today with regard to their presentation of the Austrian post-war memory. The results of this master thesis clearly demonstrate that it is only the books from 2018/2019 that manage to make the leap towards a culturally relevant exploration of collective memory and critical reflection of the Austrian post-war victim thesis.

description: We present numerical results for 2-d CP(N-1) models at θ=0 and πobtained in the D-theory formulation. In this formulation we construct an efficient cluster algorithm and we show numerical evidence for a first order transition for CP(N-1\geq 2) models at θ= π. By a finite size scaling analysis, we also discuss the equivalence in the continuum limit of the D-theory formulation of the 2-d CP(N-1) models and the usual lattice definition.
