description: We simulate scattering delays from the interstellar medium to examine the effectiveness of three estimators in recovering these delays in pulsar timing data. Two of these estimators use the more traditional process of fitting autocorrelation functions to pulsar dynamic spectra to extract scintillation bandwidths, while the third estimator uses the newer technique of cyclic spectroscopy on baseband pulsar data to recover the interstellar medium's impulse response function. We find that either fitting a Lorentzian or Gaussian distribution to an autocorrelation function or recovering the impulse response function from the cyclic spectrum are, on average, accurate in recovering scattering delays, although autocorrelation function estimators have a large variance, even at high signal-to-noise ratio (S/N). We find that, given sufficient S/N, cyclic spectroscopy is more accurate than both Gaussian and Lorentzian fitting for recovering scattering delays at specific epochs, suggesting that cyclic spectroscopy is a superior method for scattering estimation in high quality data.

description: Driving under the influence of drugs (DUID) is a growing traffic safety problem in many countries. It is estimated that 5 to 10% of medicinal drugs may impair driving due to their side effects. Despite the high number of medicinal drugs prescribed in Iran, there is a lack of a database that could provide specialized information regarding medicinal drugs and driving. Therefore, the present study aimed to design, develop, and evaluate a database for informing the general public, drivers, and healthcare providers regarding driving-impairing medicines. The Drugs-and-traffic-safety (DATS) database, which has been developed by Road Traffic Injury Research Center (RTIRC), was designed using Java, HTML, JavaScript and MySql database. After completing the testing process, pharmaceutical data (i.e., generic and brand names, route of administration, anatomical classification, etc.), the level of influence of medicinal drugs on driving, and driving-related recommendations based on the level of influence for consumers were entered into the database. A cross-sectional study, and a qualitative study as semi-structured interviews and expert panels were conducted in different target groups to evaluate the DATS. Finally, the evaluation results were used to improve the database. The quantitative and qualitative data were analyzed using SPSS 25.0 and MAXQDA-10, respectively. The DATS was the only web-based database that could be accessed online via different browsers. The database included information about 1,255 medicinal drugs, and their influence on driving was shown with four colors, i.e., green (insignificant or no effect), yellow (mild effect), orange (moderate effect), and red (severe effect). The database was designed in multiple languages, which could enable users to search for medicinal drug names in both Persian and English. Based on the quantitative results, the mean score of the DATS was 75.10 ± 16.01 (out of 100) from the public viewpoint, indicating that the users were relatively satisfied with the database. Some themes and subthemes were extracted from the qualitative section of the study which revealed the users found DATS a practical, useful, and user-friendly tool. Considering the positive feedback of users about DATS in the quantitative and qualitative evaluations, implementing DATS in Iran could provide useful advice in terms of the influence of medicinal drugs on driving to the public and traffic users. Therefore, it can raise public awareness of the risk of driving under the influence of medicinal drugs.

description: Die vorliegende Diplomarbeit setzt sich mit den Romanen Das Gastmahl auf Dubrowitza von Marta Karlweis (1921), Katharina die Große. Biografie von Gina Kaus (1935) und Der eherne Reiter von Elisabeth Freundlich (1960) auseinander. Anhand der Textanalysen soll das Bild Katharinas II. der Großen dargestellt werden, welches die Autorinnen in ihren Werken präsentieren. Diese Werke sind zunächst durch ihre Gattung des historischen Romans interessant, sowie in Bezug auf die Wiederentdeckung der vergessenen Autorinnen. Die verschiedenen Bilder Katharinas, welche in den gesamten Romanen beschrieben werden, stellen einen kritischen Blick zunächst auf die absolutistische Macht, die patriarchale Ordnung, wie auch letztlich auf die Geschlechterverhältnisse der zeitgenössischen Gesellschaft. Durch die Darstellung verschiedener Bilder Katharinas soll ein Beitrag zur Emanzipation von Frauen geleistet werden.
Development of a novel mentoring training program with simulation-based learner assessment for postprofessional Physical Therapy residency faculty

description: Background

Physical therapist (PT) education in the United States (US) has significantly evolved over the last 100 years. To meet society’s need for advanced knowledge and skills, the professional degree has transitioned to a clinical doctorate (DPT), and postprofessional residency and fellowship programs have been developed in 11 specialty and 9 subspecialty areas of PT practice. Evidence suggests that clinician educators have sparse faculty development related to the skills required to mentor post-professional learners. A framework and description of ‘mentor characteristics’ has been suggested; however, no formal, standardized program exists to nurture these skills. There is a critical need for evidence-based residency faculty development programs.

Summary of Work

In 2023, an intensive, evidence-based certificate program was designed to fill this gap. Ten mentors participated, across specialty areas of practice (Neurology, Orthopaedics, Pediatrics, Cardiopulmonary, and Sports) and from various clinical sites across the US. Before the program, participants submitted video recordings of mentoring sessions performed with a current resident, allowing course faculty to determine individualized learner needs.

The 4-day program included intense didactic content and evidence-based active learning strategies. Topics included the characteristics of effective mentors, clinical teaching, mentoring vs coaching vs instructing, master adaptive learning, faculty roles, identify formation, and communication.  Participants completed a high-fidelity simulated mentoring session employing teaching strategies learned. The simulations were specific to the participant’s area of specialty practice and setting and involved trained standardized patients and standardized residents in two scenarios (an overconfident and a timid resident). Individual and guided group reflection followed this.

Summary of Results

Participants submitted a post-program recording of a mentoring session, allowing faculty to assess the integration of newly learned skills. Pre- and post-participation videos were compared using a standardized grading rubric. Participants showed significant improvement in identified skills. In its inaugural offering, 10 participants from 7 institutions and 10 residency programs completed the program.

Discussion and Conclusion

This certificate program is the first of its kind in the US. The program answers a nationwide call for action related to excellence and value in PT residency education. The program can serve as a model for evidence-based faculty development in clinical teaching.

description: The objective of this study was to investigate the relationship between eye-catching effects and mental workload at highway tunnel entrances. Specifically, the study aimed to analyze drivers’ eye blink behavior to gain a comprehensive understanding of how visual attraction at tunnel entrances affects cognitive workload. 50 participants were recruited for the naturalistic driving experiment. Four different visually attractive driving scenarios (baseline, landscape-style architecture, tip slogan, and billboard) were selected. Eye-tracking technology was utilized to record and analyze the eye blink behavior of participating drivers. Various metrics, including blink frequency, blink duration, inter-blink interval, and pupil diameter after a blink, were measured and compared across different scenarios. The results of the study demonstrated significant differences in drivers’ eye blink behavior across the different experimental scenarios, indicating the influence of visual attraction conditions on mental workload. The presence of eye-catching stimuli (landscape-style architecture, tip slogan, and billboard scenarios) at tunnel entrances resulted in decreased blink frequency, shorter blink duration, longer inter-blink intervals, and larger pupil diameter after a blink compared to when no specific eye-catching stimuli were present (baseline condition). These findings suggest that visual attractions capture drivers’ attention, leading to increased cognitive workload and attentional demands. The findings of this study contribute to the existing literature on driver attention and mental workload, particularly in relation to eye-catching effect in tunnel environments. The presence of eye-catching stimuli at tunnel entrances can distract drivers and increase their mental workload, potentially compromising driving performance and safety. It is crucial for transportation authorities and designers to carefully consider the design and placement of visual attractions in tunnel entrances to minimize distraction and cognitive workload. By doing so, driving safety and performance can be enhanced in tunnel entrances.

description: Ein Großteil der bisherigen Untersuchungen zu Heinrich Heines Fragment ‚Der Rabbi von Bacherach‘ stellte die entstehungsgeschichtliche und die biografische Analyse in den Mittelpunkt. Aufgrund der veränderten Haltung Heines gegenüber dem Judentum wurde vorwiegend eine Inkohärenz des Fragments festgestellt. Diese Arbeit hat sich zum Ziel gesetzt, die Frage nach der Kohärenz und die Darstellung des Judentums neu zu beleuchten. Anhand von narratologischen und textimmanenten Ansätzen sollen verbindende Elemente herausgearbeitet werden. Dabei spielen die Darstellung des Judentums, der Judenverfolgung sowie des Christentums, die Unterscheidung von sensualistischen und spiritualistischen Aspekten der Religion, das jüdische Essen, Orte des jüdischen Lebens, Figurengestaltungen und jüdische Motive eine Rolle. Es konnten durch eine Analyse dieser Aspekte und der Betrachtung der Narratologie des ‚Rabbi von Bacherach‘ wiederkehrende Grundzüge in den drei Kapiteln festgestellt werden. Die vorliegende Betrachtung spricht daher für eine Kohärenz.

description: Metric type II radio bursts are usually early indicators of CME-driven shocks and other space weather phenomena in the solar corona. This paper presents a detailed investigation of the spectral properties of band-splitting type II radio bursts and their association with sunspot number. Using type II radio bursts in a frequency range 20 to 200MHz observed by CALLISTO from 2010 to 2017, it was discovered that the analyzed type II shock height, magnetic field strength, CME shock speed, and Alfven speed synchronize with the trajectory of the solar cycle 24. Also, the study revealed that the onset of the declining phase of solar cycle 24 has the highest electron density. The analysis ascertained that the frequency of type II bursts depicts a bimodal distribution during the study period, with peaks in 2012 and 2015. Further, a good correlation(with correlation factor R=0.87) was obtained between the estimated CME shock speeds from the dynamic spectra, and the associated CME speeds from SOHO-LASCO. Moreover, the study confirmed a significant correlation(R=0.8) between the absolute drift rates and the plasma frequency. Additionally, the study explored that 60% of the type II radio bursts considered in this study emanated from the western longitudes. Hence, these findings emphasize that the temporal dynamics of the physical conditions of band-splitting type II radio are essential parameters in space weather monitoring and forecasting.

description: We present a combined Brillouin light scattering and micromagnetic simulation investigation of the magnetic-field dependent spin-wave spectra in a hybrid structure made of permalloy (NiFe) artificial spin-ice (ASI) systems, composed of stadium-shaped nanoislands, deposited on the top of an unpatterned permalloy film with a nonmagnetic spacer layer. The thermal spin-wave spectra were recorded by Brillouin light scattering (BLS) as a function of the magnetic field applied along the symmetry direction of the ASI sample. Magneto-optic Kerr effect magnetometry was used to measure the hysteresis loops in the same orientation as the BLS measurements. The frequency and intensity of several spin-wave modes detected by BLS were measured as a function of the applied magnetic field. Micromagnetic simulations enabled us to identify the modes in terms of their frequency and spatial symmetry and to extract information about the existence and strength of the dynamic coupling, relevant only to a few modes of a given hybrid system. Using this approach, we suggest a way to understand if dynamic coupling between ASI and film modes is present or not, with interesting implications for the development of future three-dimensional magnonic applications and devices.

description: Several experimental investigations have observed parity violation in nuclear systems-a consequence of the weak force between quarks. We apply the $1/N_c$ expansion of QCD to the P-violating T-conserving component of the nucleon-nucleon (NN) potential. We show there are two leading-order operators, both of which affect $\vec{p}p$ scattering at order $N_c$. We find an additional four operators at $O(N_c^0 \sin^2 θ_W)$ and six at $O(1/N_c)$. Pion exchange in the PV NN force is suppressed by $1/N_c$ and $\sin^2 θ_W$, providing a quantitative explanation for its non-observation up to this time. The large-$N_c$ hierarchy of other PV NN force mechanisms is consistent with estimates of the couplings in phenomenological models. The PV observed in $\vec{p}p$ scattering data is compatible with natural values for the strong and weak coupling constants: there is no evidence of fine tuning.

description: Background



Latin America is a diverse middle-income region where one million physicians live and work. 

Patient-centered care improves health outcomes, patient and healthcare workers satisfaction, and ensures optimal use of resources; therefore it is a valid strategy, regardless of the context and resources available. 



A bottleneck to patient-centered care is to have Latin American institutional leaders and teams to understand, promote, apply and sustain this new paradigm.



Summary of Work



The goal was to design, implement and evaluate an educational intervention seeking to assess current practice gaps and transfer existing knowledge about patient-centered care from Cleveland Clinic and Hospital Italiano de Buenos Aires to fill these gaps to local Latin American teams, adapted to their actual institutional settings. It was supported by an independent educational grant from Pfizer. 



This interactive program was implemented online in Spanish, with a workload of 30 hours over eight weeks. A team-based project outline to improve patient-centered care was the main deliverable by participating institutional teams.



Two hundred and sixty-two institutions with 1161 interprofessional team members from 17 countries participated in the program; 212 institutional projects were produced. Despite being a free and intensive course over eight weeks, 50% of the participants completed it (including the final project) and received a certificate, and an extra 19% participated actively and received a letter of participation. 



Discussion and Conclusion



This project was a massive educational intervention across Spanish-speaking Latin American healthcare institutions, which included a quality improvement component designed to improve patient-centered care at the local institutional level. Many of the participating institutions were local academic leaders capable on their own to continue disseminating this knowledge in their countries. At the same time, health equity was promoted through participation of smaller institutions in the region, located far away from the major academic centers. 



Take Home Message



Massive educational interventions designed for impact on patient care are possible across Latin America, a large middle-income region with countries that share a common language and culture. A similar intervention is currently being implemented in Brazil, with local academic partners and in Portuguese.

description: A number of liquid argon time projection chambers (LAr TPC's) are being build or are proposed for neutrino experiments on long- and short baseline beams. For these detectors a distortion in the drift field due to geometrical or physics reasons can affect the reconstruction of the events. Depending on the TPC geometry and electric drift field intensity this distortion could be of the same magnitude as the drift field itself. Recently, we presented a method to calibrate the drift field and correct for these possible distortions. While straight cosmic ray muon tracks could be used for calibration, multiple coulomb scattering and momentum uncertainties allow only a limited resolution. A UV laser instead can create straight ionization tracks in liquid argon, and allows one to map the drift field along different paths in the TPC inner volume. Here we present a UV laser feed-through design with a steerable UV mirror immersed in liquid argon that can point the laser beam at many locations through the TPC. The straight ionization paths are sensitive to drift field distortions, a fit of these distortion to the linear optical path allows to extract the drift field, by using these laser tracks along the whole TPC volume one can obtain a 3D drift field map. The UV laser feed-through assembly is a prototype of the system that will be used for the MicroBooNE experiment at the Fermi National Accelerator Laboratory (FNAL).

description: Driving under the influence (DUI) of alcohol is a major public health issue that results in significant mortality, morbidity, and economic costs. Despite various penalties and interventions, DUI remains prevalent. This study examines the demographic characteristics, educational status, and involvement in motor vehicle accidents of second-time DUI offenders, aiming to identify factors influencing the success of educational interventions. Between 2018 and 2023, 151 individuals whose driver’s licenses were suspended for a second DUI offense participated in this study. All participants applied to the Adıyaman Provincial Health Directorate, located in the southeast region of Turkey, to regain their licenses. Data were collected from application documents and digital records during and after the educational program, which included identity information, demographic characteristics, reasons for alcohol consumption, license duration, education level, educational success, frequency of alcohol use, and behavior under the influence. Penalties and traffic accidents in the last 5 years were also recorded. Participants with a high school education and above had a significantly higher success rate in the educational program (P = .03). Those without penalties (P = .001) and those not involved in traffic accidents (P = .006) also showed higher success rates. Despite its limitations, this study shows that second-time DUI offenders who have previous traffic tickets or accidents are less likely to succeed in educational interventions. These findings suggest the need for tailored training programs, extended durations, and personalized evaluations to improve outcomes for these high-risk groups. Future research should explore prospective studies to confirm these results and guide intervention strategies.

description: We show that the quadratic inflation can be realized by the phase of a complex field with helicoid potential. Remarkably, this helicoid potential can be simply realized in minimal supergravity. The global $U(1)$ symmetry of the Kähler potential introduces a flat direction and evades the $η$ problem automatically. So such inflation is technically natural. The phase excursion is super-Planckian as required by the Lyth bound, while the norm of the complex field can be suppressed in the sub-Planckian region. This model resolves the ultraviolet sensitive problem of the large field inflation, besides, it also provides a new type of monodromy inflation in supersymmetric field theory with consistent field stabilization.

description: We establish the Berry-phase formulas for the angular momentum (AM) and the Hall viscosity (HV) to investigate chiral superconductors (SCs) in two and three dimensions. The AM is defined by the temporal integral of the anti-symmetric momentum current induced by an adiabatic deformation, while the HV is defined by the symmetric momentum current induced by the symmetric torsional electric field. Without suffering from the system size or geometry, we obtain the macroscopic AM $L_z = \hbar m N_0/2$ at zero temperature in full-gap chiral SCs, where $m$ is the magnetic quantum number and $N_0$ is the total number of electrons. We also find that the HV is equal to half the AM at zero temperature not only in full-gap chiral SCs as is well-known but also in nodal ones, but its behavior at finite temperature is different in the two cases.

description: Interstellar scattering (ISS) of radio pulsar emission can be used as a probe of the ionised interstellar medium (IISM) and causes corruptions in pulsar timing experiments. Two types of ISS phenomena (intensity scintillation and pulse broadening) are caused by electron density fluctuations on small scales (< 0.01 AU). Theory predicts that these are related, and both have been widely employed to study the properties of the IISM. Larger scales ($\sim$1-100\,AU) cause measurable changes in dispersion and these can be correlated with ISS observations to estimate the fluctuation spectrum over a very wide scale range. IISM measurements can often be modeled by a homogeneous power-law spatial spectrum of electron density with the Kolmogorov ($-11/3$) spectral exponent. Here we aim to test the validity of using the Kolmogorov exponent with PSR~J0826+2637. We do so using observations of intensity scintillation, pulse broadening and dispersion variations across a wide fractional bandwidth (20 -- 180\,MHz). We present that the frequency dependence of the intensity scintillation in the high frequency band matches the expectations of a Kolmogorov spectral exponent but the pulse broadening in the low frequency band does not change as rapidly as predicted with this assumption. We show that this behavior is due to an inhomogeneity in the scattering region, specifically that the scattering is dominated by a region of transverse size $\sim$40\,AU. The power spectrum of the electron density, however, maintains the Kolmogorov spectral exponent from spatial scales of 5$\times10^{-6}$\,AU to $\sim$100\,AU.

A Rua Fala: Pixação como expressão cultural e seus desdobramentos na preservação de patrimônio cultural
Creators: name: Santos da Cunha, Luana
Publisher: name: Zenodo
Year: 2024

description: A pixação é uma expressão artística urbana que surgiu no Rio de Janeiro na década de 1970, desafiando normas e ocupando espaços públicos com mensagens e estética única. Ela é vista como uma forma de comunicação e reivindicação, representando um grito poético da periferia para o centro da cidade. A documentação da pixação é crucial, transcendendo a captura visual para se tornar um registro histórico e cultural significativo. Este trabalho investiga a relação entre as práticas de documentação da pixação e as teorias de conservação, explorando como a pixação impacta fisicamente e simbolicamente o ambiente urbano, a identidade cultural e a memória coletiva. O estudo analisa um grupo de pixadores no Rio de Janeiro, documentando suas práticas e entrevistando membros para entender suas motivações e impactos sociais. A metodologia inclui análise qualitativa de entrevistas e dados, contribuindo para um debate mais amplo sobre a conservação e restauração do patrimônio cultural. A abordagem teórica incorpora perspectivas de estudiosos como Spinelli e Viñas, que enfatizam a subjetividade e o contexto social na conservação. Este trabalho também avalia o impacto da pixação sobre o patrimônio cultural e as políticas urbanas, buscando uma compreensão mais profunda das práticas de documentação e sua integração com a conservação e restauração. A pesquisa visa promover um diálogo sobre a pixação e a conservação urbana, reconhecendo a pixação como parte integrante do cenário urbano e explorando soluções que conciliem expressão artística e qualidade do espaço público.
A New Class of Nascent Eclipsing Binaries with Extreme Mass Ratios

description: Early B-type main-sequence (MS) stars (M$_1$ = 5-16 M$_{\odot}$) with closely orbiting low-mass stellar companions (q = M$_2$/M$_1$ < 0.25) can evolve to produce Type Ia supernovae, low-mass X-ray binaries, and millisecond pulsars. However, the formation mechanism and intrinsic frequency of such close extreme mass-ratio binaries have been debated, especially considering none have hitherto been detected. Utilizing observations of the Large Magellanic Cloud galaxy conducted by the Optical Gravitational Lensing Experiment, we have discovered a new class of eclipsing binaries in which a luminous B-type MS star irradiates a closely orbiting low-mass pre-MS companion that has not yet fully formed. The primordial pre-MS companions have large radii and discernibly reflect much of the light they intercept from the B-type MS primaries ($Δ$I$_{\rm refl}$ = 0.02-0.14 mag). For the 18 definitive MS + pre-MS eclipsing binaries in our sample with good model fits to the observed light curves, we measure short orbital periods P = 3.0-8.5 days, young ages $τ$ = 0.6-8 Myr, and small secondary masses M$_2$ = 0.8-2.4 M$_{\odot}$ (q = 0.07-0.36). The majority of these nascent eclipsing binaries are still associated with stellar nurseries, e.g. the system with the deepest eclipse $Δ$I$_1$ = 2.8 mag and youngest age $τ$ = 0.6$\pm$0.4 Myr is embedded in the bright H II region 30 Doradus. After correcting for selection effects, we find that (2.0$\pm$0.6)% of B-type MS stars have companions with short orbital periods P = 3.0-8.5 days and extreme mass ratios q = 0.06-0.25. This is $\approx$10 times greater than that observed for solar-type MS primaries. We discuss how these new eclipsing binaries provide invaluable insights, diagnostics, and challenges for the formation and evolution of stars, binaries, and H II regions.

description: We study the resistivity scaling in nanometer-sized metallic wires due to surface roughness and grain-boundaries, currently the main cause of electron scattering in nanoscaled interconnects. The resistivity has been obtained with the Boltzmann transport equation, adopting the relaxation time approximation (RTA) of the distribution function and the effective mass approximation for the conducting electrons. The relaxation times are calculated exactly, using Fermi's golden rule, resulting in a correct relaxation time for every sub-band state contributing to the transport. In general, the relaxation time strongly depends on the sub-band state, something that remained unclear with the methods of previous work. The resistivity scaling is obtained for different roughness and grain-boundary properties, showing large differences in scaling behavior and relaxation times. Our model clearly indicates that the resistivity is dominated by grain-boundary scattering, easily surpassing the surface roughness contribution by a factor of 10.

title: Die Erschließungsstrategie der Ernst Krenek Institut Privatstiftung
Creators: name: Kvarda, Hannah
Year: 2021

description: Diese Arbeit widmet sich der Erschließungspraxis des Ernst Krenek Instituts und beleuchtet sie im Kontext von aktuellen Standardisierungsbestrebungen. Das Ernst Krenek Institut ist eine Gedächtnisorganisation, die einen umfangreichen Teilnachlass des Komponisten und Schriftstellers Ernst Krenek verwahrt und sich für die Erhaltung und Verbreitung seines Werks einsetzt. Die Ausrichtung der Institution bringt spezifische Anforderungen an die Erschließung mit sich, die hier aufgezeigt werden. Eine umfassende Bestandsanalyse gibt einen Überblick über die Bestände. Die Analyse der zur Verfügung stehenden Erschließungsinstrumente sowie der Erschließungsdaten zeigt die Schwierigkeit, einen heterogenen, aber in sich geschlossenen Bestand mit allen Querbezügen abzubilden. Einerseits werden die Problemfelder einer Insellösung deutlich, andererseits kann gezeigt werden, dass eine bibliothekarische Erschließung in mancher Hinsicht zu kurz greift. Außerdem werden die Potenziale, die sich aus einer Zusammenarbeit von Erschließung und Digital Humanities ergeben, aufgezeigt.

description: Closed cycle $He^{3}-He^{4}$ dilution cryostats became the platform of choice in quantum sciences in the era of helium shortage. However, in many experiments, the mechanical vibrations induced by the pulsed cryocoolers present a significant drawback reflected both in electronic and mechanical noises. Here, we present a hybrid dilution cryostat platform; we have automated a commercial closed-cycle system to operate on a cryocooler or on a liquid helium battery. We implemented a scanning SQUID microscope in the hybrid dilution refrigerator. In this work we show the design of the hybrid setup and how its operation eliminates vibration artefacts in magnetic imaging.

Strong P invariance, neutron EDM and minimal Left-Right parity at LHC

description: In the minimal Left-Right model the choice of left-right symmetry is twofold: either generalized parity $\mathcal P$ or charge conjugation $\mathcal C$. In the minimal model with spontaneously broken strict $\mathcal P$, a large tree-level contribution to strong CP violation can be computed in terms of the spontaneous phase $α$. Searches for the neutron electric dipole moments then constrain the size of $α$. Following the latest update on indirect CP violation in the kaon sector, a bound on $W_R$ mass at $20 \text{TeV}$ is set. Possible ways out of this bound, either by an additional relaxation mechanism or explicit breaking of $\mathcal P$ are considered. To this end, the chiral loop of the neutron electric dipole moment at next-to-leading order is re-computed and provides an estimate of the weak contribution. Combining this constraint with other CP violating observables in the kaon sector allows for $M_{W_R} \gtrsim 3 \text{TeV}$. On the other hand, $\mathcal C$-symmetry is free from such constraints, leaving the right-handed scale within the experimental reach.

title: Kleingärten
Creators: name: Helml, Claudia
Year: 2021

description: Schon seit mehr als einem Jahrhundert sind Kleingärten für viele Menschen in Europa aus ihrem Leben nicht wegzudenken. Die vorliegende Arbeit hat sich daher zum Ziel gesetzt, sowohl die historischen Entwicklungen - vom Armengarten zum Erholungsgarten - prägnant darzustellen, als auch die damit verbundenen gesetzlichen Grundlagen zu behandeln. Insbesondere wurde beim Verfassen dieser Diplomarbeit großer Wert auf die jüngeren baulichen Veränderungen in den Kleingärten gelegt, die seit der Einführung ganzjähriger Wohnmöglichkeit im Jahr 1992 zu beobachten sind. Ein weiterer inhaltlicher Aspekt ist ein kritischer Blick auf Einbettung der Anlagen in das Wiener Stadtbild, sowie die Entwicklung des Grünraums. Die herrschenden Differenzen in der Einschätzung der Kleingärten als urbanes Phänomen zwischen Stadtplanung, Regierung und KleingärtnerInnen werden ebenso beleuchtet. Die Arbeit baut auf den Erkenntnissen und Informationen zahlreicher einschlägiger Studien und statistischer Werke auf, und wird durch Experteninterviews (nach Ingenkamp & Lissmann, 2008), Interviews mit KleingärtnerInnen, sowie durch die Durchführung einer schriftlichen Befragung ergänzt. Durch Auswertung der daraus gewonnenen Daten, sowie einer qualitativen Beobachtung in den festgelegten Untersuchungsgebieten des zweiten und vierzehnten Wiener Gemeindebezirkes, konnten die Thesen dieser Arbeit überprüft und weitere interessante Einblicke in das aktuelle Problemfeld „Kleingärten“ gewonnen werden. Abschließend verweist die vorliegende Arbeit auf mögliche Zukunftspotentiale der Wiener Kleingärten im Sinne des Klimaschutzes.

title: Soziale Medien und Blogging im Umgang mit Krankheitskrisen
Creators: name: Brugger, Anna
Year: 2021

description: Das Schreiben über Krebs nimmt sowohl im privaten Kontext wie auch in der Öffentlichkeit zu. Mit der vorliegenden Arbeit soll am Beispiel von Krebserkrankungen gezeigt werden, wie die sozialen Medien als unterstützendes Tool zum Einsatz kommen können. Die zentrale Fragestellung befasst sich damit, welche Online-Praktiken krebskranken Menschen oder ihren Angehörigen zur Verfügung stehen und welchen Stellenwert diese Praktiken im Leben der Betroffenen einnehmen. Dazu wurden Interviews mit KrebsbloggerInnen und Mitgliedern von Online-Gruppen geführt, ergänzt durch die Beobachtung von Krebsblogs und besagten Gruppen. Der Austausch in den digitalen sozialen Medien und darüber hinaus, unterstützt die betroffenen Menschen im selbstbestimmten Umgang mit Krankheitskrisen. Die Teilnehmenden geben einander Empfehlungen für Behandlungen und es wird Zuversicht gegenüber der jeweiligen Behandlungsmethode hergestellt. Die Betroffenen können durch die Auswahl der digitalen Plattform und ihren Regelungen den Grad der Privatheit oder Öffentlichkeit bestimmen. Das Wir-Gefühl in den Communities trägt zur Identitätsbildung als KrebspatientInnen bei, während der Austausch die Reflexion der Teilnehmenden unterstützt und alternative Sichtweisen ermöglicht.

description: This thesis contains three self-contained chapters. In Chapter One, we go to the races. We come last, and learn that this will never be published. We also discover the deep \bf{Origins of Misogyny}. Chapter Two shows that \bf{There is No Crowding Out} in the private responses of individuals in the face of government intervention. Chapter Three is a \bf{SpaceTime Odyssey} which shows that \it{De Gustibus Est Disputandum}, apart from when \it{De Gustibus Non Est Disputandum}. We parameterise these differences and so bring clarity to the question of when and under what circumstances preferences are stable.

description: Let C_n denote the representation category of a finite supergroup generated by purely odd n-dimensional vector space. We compute the Brauer-Picard group BrPic(C_n) of C_n. This is done by identifying BrPic(C_n) with the group of braided tensor autoequivalences of the Drinfeld center of C_n and studying the action of the latter group on the categorical Lagrangian Grassmannian of C_n. We show that this action corresponds to the action of a projective symplectic group on a classical Lagrangian Grassmannian.
