description: Diese Bachelorarbeit entstand im Jahr 2023 im Rahmen des Studiums Soziale Arbeit an der Hochschule Luzern. Sie thematisiert die Ansprechbarkeit auf das (vor)pubertäre Körperschema und den damit verbundenen sozialen Problemen. Ziel war es, durch qualitative Expert:inneninterviews und der anschliessenden Auswertung mit der Grounded Theory Methodologie aufzuschlüsseln, welche sozialen Probleme Fachpersonen aus bestehenden Präventionsangeboten wahrnehmen und wie diesen begegnet wird. Die Ergebnisse ermöglichen einen Einblick in bestehende Präventionsangebote und die damit verbundenen Herausforderungen, mit denen Fachpersonen konfrontiert sind. Dabei sticht insbesondere die unzureichende Angehörigenunterstützung hervor. Des Weiteren wird deutlich, dass eine flächendeckende Präventionsarbeit aufgrund fehlender finanzieller Unterstützung seitens der Kantone nicht realisiert werden kann. Diese Einschränkung ist auf mangelnde politische und gesellschaftliche Konformität mit dem Thema zurückzuführen. Ein weiteres bedeutendes Ergebnis ist die vernachlässigte Ausbildung von Fachpersonen verschiedener Disziplinen, was sich negativ auf den Umgang mit sozialen Problemen auswirkt. In Bezug auf die Rolle der Sozialen Arbeit bedeutet dies, dass aufgrund der fehlenden Einbeziehung soziale Probleme nicht angegangen werden können. Die befragten Personen äussern den Wunsch nach fachlicher Unterstützung seitens der Sozialen Arbeit und betonen die Notwenigkeit einer Einbindung der Profession in Präventionsangebote.

description: We present a detailed weak-lensing and X-ray study of the Frontier Fields galaxy cluster Abell 370, one of the most massive known lenses on the sky, using wide-field BRz Subaru/Sprime-Cam and Chandra X-ray observations. By combining two-dimensional (2D) shear and azimuthally averaged magnification constraints derived from Subaru data, we perform a lensing mass reconstruction in a free-form manner, which allows us to determine both radial structure and 2D morphology of the cluster mass distribution. In a triaxial framework assuming a Navarro-Frenk-White density profile, we constrain the intrinsic structure and geometry of the cluster halo by forward modeling the reconstructed mass map. We obtain a halo mass $M_{200}=(1.54 \pm 0.29)\times 10^{15}h^{-1}M_\odot$, a halo concentration $c_{200}=5.27 \pm 1.28$, and a minor-major axis ratio $q_a=0.62 \pm 0.23$ with uninformative priors. Using a prior on the line-of-sight alignment of the halo major axis derived from binary merger simulations constrained by multi-probe observations, we find that the data favor a more prolate geometry with lower mass and lower concentration. From triaxial lens modeling with the line-of-sight prior, we find a spherically enclosed gas mass fraction of $f_\mathrm{gas}=(8.4 \pm 1.0)\%$ at $0.7h^{-1}$ Mpc $\sim 0.7r_{500}$. When compared to the hydrostatic mass estimate from Chandra observations, our triaxial weak-lensing analysis yields spherically enclosed mass ratios of $1-b \equiv M_\mathrm{HE}/M_\mathrm{WL} = 0.56 \pm 0.09$ and $0.51 \pm 0.09$ at $0.7h^{-1}$ Mpc with and without using the line-of-sight prior, respectively. Since the cluster is in a highly disturbed dynamical state, this represents the likely maximum level of hydrostatic bias in galaxy clusters.

description: Embedding QCD into the standard model breaks various symmetries of QCD explicitly, especially C and P. While these effects are usually perturbatively small, they can be amplified in extreme environments like merging neutron stars or by the interplay with new physics. To correctly treat these cases requires fully backcoupled calculations. To pave the way for later investigations of hadronic physics, we study the QCD quark propagator coupled to an explicit breaking. This substantially increases the tensor structure even for this simplest correlation function. To cope with the symmetry structure, and covering all possible quark masses, from the top quark mass to the chiral limit, we employ Dyson-Schwinger equations. While at weak breaking the qualitative effects have similar trends as in perturbation theory, even moderately strong breakings lead to qualitatively different effects, non-linearly amplified by the strong interactions.

description: With the high sensitivity and wide-field coverage of the Square Kilometre Array (SKA), large samples of explosive transients are expected to be discovered. Radio wavelengths, especially in commensal survey mode, are particularly well suited for uncovering the complex transient phenomena. This is because observations at radio wavelengths may suffer less obscuration than in other bands (e.g. optical/IR or X-rays) due to dust absorption. At the same time, multiwaveband information often provides critical source classification rapidly than possible with only radio band data. Therefore, multiwaveband observational efforts with wide fields of view will be the key to progress of transients astronomy from the middle 2020s offering unprecedented deep images and high spatial and spectral resolutions. Radio observations of gamma ray bursts (GRBs) with SKA will uncover not only much fainter bursts and verifying claims of sensitivity limited population versus intrinsically dim GRBs, they will also unravel the enigmatic population of orphan afterglows. The supernova rate problem caused by dust extinction in optical bands is expected to be lifted in the SKA era. In addition, the debate of single degenerate scenario versus double degenerate scenario will be put to rest for the progenitors of thermonuclear supernovae, since highly sensitive measurements will lead to very accurate mass loss estimation in these supernovae. One also expects to detect gravitationally lensed supernovae in far away Universe in the SKA bands. Radio counterparts of the gravitational waves are likely to become a reality once SKA comes online. In addition, SKA is likely to discover various new kinds of transients.

The Sources of Apparently Non-Repeating FRB
Creators: name: Katz, J. I.
Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: There are insufficient catastrophic events (collapse, explosion or merger of stars or compact objects) to explain the cosmologically local rate of apparently non-repeating FRB if each such catastrophic event produces a single FRB. Unless produced by some novel and unsuspected but comparatively frequent event, apparently non-repeating FRB must actually repeat many times in the lifetimes of their sources. Yet no such infrequent repetitions (in contrast to the frequent activity of FRB known to repeat) have been observed, constraining their repetition rates and active lifetimes. The absence of more frequent weaker but detectable repetitive outbursts in apparent non-repeaters resembles the distribution of SGR outbursts, with a large gap between giant outbursts and lesser outbursts. This suggests mini-SGR as sources, more energetic than SGR 1935$+$2154 associated with FRB 200428 but less energetic than SGR 1806$-$20 that had no associated FRB. Their largest radio outbursts would, at cosmological distances, be apparently non-repeating FRB and their X-ray and gamma-ray outbursts would be undetectable. The large gap between the strongest outburst of FRB 200428 and its lesser outbursts resembles the gamma-ray properties of individual well-observed SGR; at twenty times its actual distance, FRB 200428 would have been an apparent non-repeater.

Approaching the Computational Color Constancy as a Classification Problem through Deep Learning

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Computational color constancy refers to the problem of computing the illuminant color so that the images of a scene under varying illumination can be normalized to an image under the canonical illumination. In this paper, we adopt a deep learning framework for the illumination estimation problem. The proposed method works under the assumption of uniform illumination over the scene and aims for the accurate illuminant color computation. Specifically, we trained the convolutional neural network to solve the problem by casting the color constancy problem as an illumination classification problem. We designed the deep learning architecture so that the output of the network can be directly used for computing the color of the illumination. Experimental results show that our deep network is able to extract useful features for the illumination estimation and our method outperforms all previous color constancy methods on multiple test datasets.

description: Experimental grain growth observations often deviate from grain growth simulations, revealing that the governing rules for grain boundary motion are not fully understood. A novel deep learning model was developed to capture grain growth behavior from training data without making assumptions about the underlying physics. The Physics-Regularized Interpretable Machine Learning Microstructure Evolution (PRIMME) model consists of a multi-layer neural network that predicts the likelihood of a point changing to a neighboring grain. Here, we demonstrate PRIMME's ability to replicate two-dimensional normal grain growth by training it with Monte Carlo Potts simulations. The trained PRIMME model's grain growth predictions in several test cases show good agreement with analytical models, phase-field simulations, Monte Carlo Potts simulations, and results from the literature. Additionally, PRIMME's adaptability to investigate irregular grain growth behavior is shown. Important aspects of PRIMME like interpretability, regularization, extrapolation, and overfitting are also discussed.

description: Using the UltraVISTA DR1 and 3D-HST catalogs, we construct a stellar-mass-complete sample, unique for its combination of surveyed volume and depth, to study the evolution of the fractions of quiescent galaxies, moderately unobscured star-forming galaxies, and dusty star-forming galaxies as a function of stellar mass over the redshift interval $0.2 \le z \le 3.0$. We show that the role of dusty star-forming galaxies within the overall galaxy population becomes more important with increasing stellar mass, and grows rapidly with increasing redshift. Specifically, dusty star-forming galaxies dominate the galaxy population with $\log{(M_{\rm star}/M_{\odot})} \gtrsim 10.3$ at $z\gtrsim2$. The ratio of dusty and non-dusty star-forming galaxies as a function of stellar mass changes little with redshift. Dusty star-forming galaxies dominate the star-forming population at $\log{(M_{\rm star}/M_{\odot})} \gtrsim 10.0-10.5$, being a factor of $\sim$3-5 more common, while unobscured star-forming galaxies dominate at $\log{(M_{\rm star}/M_{\odot})} \lesssim 10$. At $\log{(M_{\rm star}/M_{\odot})} > 10.5$, red galaxies dominate the galaxy population at all redshift $z<3$, either because they are quiescent (at late times) or dusty star-forming (in the early universe).

description: We propose a new method to compute magnetic surfaces that are parametrized in Boozer coordinates for vacuum magnetic fields. We also propose a measure for quasi-symmetry on the computed surfaces and use it to design coils that generate a magnetic field that is quasi-symmetric on those surfaces. The rotational transform of the field and complexity measures for the coils are also controlled in the design problem. Using an adjoint approach, we are able to obtain analytic derivatives for this optimization problem, yielding an efficient gradient-based algorithm. Starting from an initial coil set that presents nested magnetic surfaces for a large fraction of the volume, our method converges rapidly to coil systems generating fields with excellent quasi-symmetry and low particle losses. In particular for low complexity coils, we are able to significantly improve the performance compared to coils obtained from the standard two-stage approach, e.g.~reduce losses of fusion-produced alpha particles born at half-radius from $17.7\%$ to $6.6\%$. We also demonstrate 16-coil configurations with alpha loss < $1\%$ and neoclassical transport magnitude $ε_{\mathrm{eff}}^{3/2}$ less than approximately $5\times 10^{-9}.$
THE POTENTIAL OF HONEY THERAPY FOR MENSTRUAL CRAMPS

Subjects: Health counselling

description: Period cramps can cause significant discomfort and negatively impact a woman’s life. While painkillers are commonly used for relief, they may have side effects and potential addiction risks. However, natural remedies such as honey offer a promising alternative. Regular exercise, yoga, and a healthy lifestyle can help ease the pain, but honey provides additional relief without side effects. This article explores various ways to utilize honey to alleviate menstrual cramps naturally. Combining honey with cinnamon, ginger, fennel, or chamomile can provide effective solutions due to their anti-inflammatory properties. It is essential to choose natural, pure honey without added preservatives or sugar. Additionally, maintaining a balanced diet, staying hydrated, and avoiding caffeine, alcohol, and junk food during periods can contribute to overall well-being and minimize discomfort. This article is based on the secondary source of data and limited to effect of honey on women’s health during the menstruation.
Schocknachricht: Sexualisierte Gewalt an Kindern: Eine Forschungsarbeit über den Umgang von Fachpersonen der Sozialen Arbeit mit Aussagen zu erlebter sexualisierter Gewalt von Kindern unter 16 Jahren

description: Jedes siebte Kind - das sind drei Kinder pro Schulklasse (Lavoyer, 2022, S. 10– 20). Die Anzahl betroffener Kinder von sexualisierter Gewalt mit Körperkontakt durch Erwachsene oder ältere Kinder ist gross. Im Hinblick auf eine massiv höhere Dunkelziffer schier unfassbar. Aus diesem Grund erstaunt es nicht, dass auch Fachpersonen der Sozialen Arbeit, welche mit Kindern und Jugendlichen arbeiten, mit der Thematik konfrontiert werden können. Eine angemessene Handhabung und umfangreiche Kenntnisse zur Thematik sind in einem solchen Fall deshalb unabdingbar. Die nachfolgende Arbeit beschäftigt sich mit der Offenlegung von Kindern, welche sexualisierte Gewalt erleben oder erlebt haben und sich damit an Fachpersonen der Sozialen Arbeit wenden. Die Forschungsfrage: «Wie ist der praktische Umgang von Fachpersonen der Sozialen Arbeit mit Botschaften sexualisierter Gewalt an Kindern unter 16 Jahren?» wurde anhand qualitativer Leitfadeninterviews und einer quantitativen Online-Umfrage eruiert und mit existierender Fachliteratur verglichen. Es wurde herausgearbeitet, dass die befragten Fachpersonen in der Praxis mehrheitlich zielführend und unterstützend mit betroffenen Kindern arbeiten. Gleichzeitig fehlte vielerorts eine ganzheitliche Wissensvermittlung durch die Ausbildungsstätten und auch in den Institutionen waren häufig wenig bis keine konkreten Hilfsangebote für Fachpersonen vorhanden. Dies trug dazu bei, dass sich viele Fachpersonen im Umgang mit der Thematik nicht sicher oder sogar sehr unsicher fühlen. Für die Praxis bedeutet dies folglich, dass vermehrt Konzepte und Leitfäden in diesem Bereich wünschenswert wären und dass eine vertieftere Wissensvermittlung durch Hochschulen hilfreich sein könnte.

description: We investigated optical spin orientation and dynamic nuclear polarization (DNP) in individual self-assembled InGaAs/GaAs quantum dots (QDs) doped by a single Mn atom, a magnetic impurity providing a neutral acceptor A$^0$ with an effective spin $J=1$. We find that the spin of an electron photo-created in such a quantum dot can be efficiently oriented by a quasi-resonant circularly-polarized excitation. For the electron spin levels which are made quasi-degenerate by a magnetic field compensating the exchange interaction $Δ_e$ with A$^0$, there is however a full depolarization due the anisotropic part of the exchange. Still, in most studied QDs, the spin polarized photo-electrons give rise to a pronounced DNP which grows with a longitudinal magnetic field until a critical field where it abruptly vanishes. For some QDs, several replica of such DNP sequence are observed at different magnetic fields. This striking behavior is qualitatively discussed as a consequence of different exchange interactions experienced by the electron, driving the DNP rate via the energy cost of electron-nucleus spin flip-flops.

description: Over the past few years, we have seen several cyber incidents being reported, where some of the primary causes were the lack of proper security controls onboard the ship and crew awareness on cybersecurity. In response to the growing cyber threat landscape in the maritime sector, we have developed a set of guidelines for maritime cyber risk management, focusing on four major shipboard Operational Technology (OT) systems that are crucial for the day-to-day operation of ships. These four OT systems are: Communication Systems, Propulsion, Machinery and Power Control Systems, Navigation Systems and Cargo Management Systems. The guidelines identify the cyber risks in each of the OT systems and recommend the necessary actions that can be taken to manage risks in each shipboard OT system. In this paper, we introduce the new guidelines, which include cyber risks, mitigation measures, cyber risk assessment, and a checklist to help shipowners and maritime authorities assess and enhance cyber hygiene of their vessels. Our guidelines have been disseminated by the Maritime and Port Authority of Singapore (MPA) to owners and operators of the Singapore Registry of Ships for their reference and use.

description: This article is devoted to the thermomechanical characterization of clay taken from the Balkuy area (Latitude: 12.30 North; Longitude: -1.47 West), a locality of south of Ouagadougou in Burkina Faso. Thermal characterizations were carried out on clay materials formulated from different concentrations (or decoction) of nere pod. The results obtained show an improvement in thermal conductivity of 31.25%, 36.87%, 46.87%, 65.93% and 73.12% respectively when the formulation is made with a concentration of 4g/l to 20g/l in 4g/l steps, respectively. The diffusivity increases by 35.25% for a clay formulated with a concentration of 16g/l corresponding to an optimum formulation. However, the density of the different formulations increases respectively by 2.64%, 16.05%, 17.34%, 18.25% and 18.85% when the clay is formulated with a concentration of 4g/l to 20g/l following an evolution step of 4g/l.  Increasing the concentration of nere pods in clay improves compressive strength. The mechanical strength of clay mixed with water is 1.181 MPa. This strength is multiplied by 10.30 when the clay is mixed with a concentration of 8g/l, for a curing period of 28 days. This concentration of  8g/l of nere pod corresponds to an optimum level that improves compressive strength .

description: The sale as well as lease transactions of agricultural land affect both the distributional and production pattern which have serious policy consequences in a developing economy. The study, using the qualitative analytical methods of logit function, identified the socio-economic characters which influenced the land sale or lease decisions of farmers in a highly fertile and developed region of India. The study found that with an increase in the size of holding, the farmers showed greater probability to (i) buy more land in the sale market, and (ii) lease-out land in the lease market. The former tendency leads to dispossession of small holders and, consequently, adverse effects on distribution of land and production of subsistence crops needed for the growing population, while the latter tendency offsets these adverse effects through favourable redistribution atleast of the operated area as generally small holders lease-in land in the region to optimise their family labour and financial resources. Among the other variables, the increase in age and addiction to drugs or gambling in family are found to be raising the probability of being a seller or lessor. It is argued that leasing of agricultural land be accorded fully recognised legal status with some regulatory controls.

description: Tontines were once a popular type of mortality-linked investment pool. They promised enormous rewards to the last survivors at the expense of those died early. And, while this design appealed to the gambling instinc}, it is a suboptimal way to generate retirement income. Indeed, actuarially-fair life annuities making constant payments -- where the insurance company is exposed to longevity risk -- induce greater lifetime utility. However, tontines do not have to be structured the historical way, i.e. with a constant cash flow shared amongst a shrinking group of survivors. Moreover, insurance companies do not sell actuarially-fair life annuities, in part due to aggregate longevity risk. We derive the tontine structure that maximizes lifetime utility. Technically speaking we solve the Euler-Lagrange equation and examine its sensitivity to (i.) the size of the tontine pool $n$, and (ii.) individual longevity risk aversion $γ$. We examine how the optimal tontine varies with $γ$ and $n$, and prove some qualitative theorems about the optimal payout. Interestingly, Lorenzo de Tonti's original structure is optimal in the limit as longevity risk aversion $γ\to \infty$. We define the natural tontine as the function for which the payout declines in exact proportion to the survival probabilities, which we show is near-optimal for all $γ$ and $n$. We conclude by comparing the utility of optimal tontines to the utility of loaded life annuities under reasonable demographic and economic conditions and find that the life annuity's advantage over the optimal tontine is minimal. In sum, this paper's contribution is to (i.) rekindle a discussion about a retirement income product that has been long neglected, and (ii.) leverage economic theory as well as tools from mathematical finance to design the next generation of tontine annuities.

description: The Density of States Functional Fit Approach (DoS FFA) is a recently proposed modern density of states technique suitable for calculations in lattice field theories with a complex action problem. In this article we present an exploratory implementation of DoS FFA for the SU(3) spin system at finite chemical potential $μ$ - an effective theory for the Polyakov loop. This model has a complex action problem similar to the one of QCD but also allows for a dual simulation in terms of worldlines where the complex action problem is solved. Thus we can compare the DoS FFA results to the reference data from the dual simulation and assess the performance of the new approach. We find that the method reproduces the observables from the dual simulation for a large range of $μ$ values, including also phase transitions, illustrating that DoS FFA is an interesting approach for exploring phase diagrams of lattice field theories with a complex action problem.

description: The current Cepheid-calibrated distance ladder measurement of $H_0$ is reported to be in tension with the values inferred from the cosmic microwave background (CMB), assuming standard cosmology. However, some tip of the red giant branch (TRGB) estimates report $H_0$ in better agreement with the CMB. Hence, it is critical to reduce systematic uncertainties in local measurements to understand the Hubble tension. In this paper, we propose a uniform distance ladder between the second and third rungs, combining SNe~Ia observed by the Zwicky Transient Facility (ZTF) with a TRGB calibration of their absolute luminosity. A large, volume-limited sample of both calibrator and Hubble flow SNe~Ia from the \emph{same} survey minimizes two of the largest sources of systematics: host-galaxy bias and non-uniform photometric calibration. We present results from a pilot study using existing TRGB distance to the host galaxy of ZTF SN~Ia SN 2021rhu (aka ZTF21abiuvdk) in NGC7814. Combining the ZTF calibrator with a volume-limited sample from the first data release of ZTF Hubble flow SNe~Ia, we infer $H_0 = 76.94 \pm 6.4\, {\rm km}\,{\rm s^{-1}}\,{\rm Mpc^{-1}}$, an $8.3 \%$ measurement. The error budget is dominated by the single object calibrating the SN~Ia luminosity in this pilot study. However, the ZTF sample includes already five other SNe~Ia within $\sim$ 20 Mpc for which TRGB distances can be obtained with HST. Finally, we present the prospects of building this distance ladder out to 80 Mpc with JWST observations of more than one hundred ZTF SNe~Ia.

organization identifier

description: The Research Organization Registry (ROR) launched in 2019 and now contains open persistent identifiers (ROR IDs) and associated metadata for more than 97,000 organizations. As a new arrival in the persistent identifier ecosystem, ROR is uniquely focused on solving the specific problem of how to identify the research organization associated with published research outputs, and on solving this problem with open infrastructure and with extensive community input. Wide adoption of ROR across the research landscape is key to enabling clean, consistent, and open metadata for tracking research outputs by institutions. ROR IDs are already supported in the DataCite metadata schema and will soon be supported in Crossref. A number of repositories and platforms have implemented ROR in their systems, taking advantage of ROR’s open API and public data dumps. Additional integrations are forthcoming as the project matures. In this session, we will provide an overview of the ROR registry, demonstrate how ROR IDs are being used, share upcoming milestones for the project, and solicit audience questions and feedback.
title: (Un-)sichtbare Diskurse - Transidentität und Migration in Mithu Sanyals "Identitti" und Fatma Aydemirs "Dschinns"
Creators: name: Mehdizadeh Baghbani, Panthea
Year: 2023

description: Die Romane Identitti von Mithu Sanyal (2021) und Dschinns von Fatma Aydemir (2022) beinhalten die Auseinandersetzung mit migrationsbezogenen Diskursen in Überschneidung mit einem der Queer-Theory entlehnten Trans-Begriff. Ausgehend von den unterschiedlichen Darstellungen und Kontextualisierungen der Prozesse von Transition und Grenzquerung wird untersucht, wie Transidentität und Migration in den ausgewählten Romanen konstruiert und sichtbar bzw. unsichtbar werden. Als Grundlage des theoriegeleiteten Vergleichs dient insbesondere Homi Bhabhas Konzept des Dritten Raumes, der als Denkfigur die Schnittpunkte postkolonialer sowie queerer Theoriebildung umfasst. Die Analyse der handlungstragenden Figuren und ihrer Interaktionskontexte verweist auf eine wesentliche Bedeutung der Sprache zur Identitätskonstruktion. Hinsichtlich sozialer Kategorien wie Race und Gender dient das verbale Bekenntnis in der Interaktion als einende Praktik zur Identitätsfindung. Dagegen trägt die Sprachlosigkeit zum Verschwinden von Diskursen und demnach der Unsichtbarkeit von Figuren und Identitäten bei. Während Aydemir den Trans-Begriff in einem genderspezifischen Kontext gebraucht und die Repräsentation queerer Identität durch Implikationen herausfordert, zeigt Sanyals Roman auf, wie die Aneignung des Begriffs transracial in Bezug auf die soziale Kategorie Race als hegemoniales Instrument dient, das hierarchische Oppositionen reproduziert und in ihrer Wirkungsweise manifestiert.

description: Period cramps can cause significant discomfort and negatively impact a woman's life. While painkillers are commonly used for relief, they may have side effects and potential addiction risks. However, natural remedies such as honey offer a promising alternative. Regular exercise, yoga, and a healthy lifestyle can help ease the pain, but honey provides additional relief without side effects. This article explores various ways to utilize honey to alleviate menstrual cramps naturally. Combining honey with cinnamon, ginger, fennel, or chamomile can provide effective solutions due to their antiinflammatory properties. It is essential to choose natural, pure honey without added preservatives or sugar. Additionally, maintaining a balanced diet, staying hydrated, and avoiding caffeine, alcohol, and junk food during periods can contribute to overall well-being and minimize discomfort. This article is based on the secondary source of data an
Welche Bedeutung hat das Musikhören für dich? Eine qualitative Forschungsarbeit für die sozialpädagogische Betreuung in der Sozialpsychiatrie

description: Diese qualitative Forschungsarbeit widmet sich dem Potenzial des Musikhörens im Umgang mit psychischen Erkrankungen, um Vorschläge zur Nutzung dieses Mediums in der sozialpädagogischen Betreuung im Praxisfeld der Sozialpsychiatrie zu formulieren. Die sozialpsychiatrischen Leitideen sowie das Verständnis von Gesundheit und Krankheit in der Sozialpsychiatrie werden anhand von Konzepten und Modellen erklärt. Nachfolgend werden musikpsychologische Erklärungen der Wirkung von Musik festgehalten. Relevante musiktherapeutische sowie musikalische Methoden in der Sozialen Arbeit werden vorgestellt. Anhand dieser Erkenntnisse wurden vier Leitfadeninterviews mit Menschen mit psychischen Erkrankungen durchgeführt, um zu erforschen, inwiefern sie das Musikhören zur Selbsthilfe nutzen. Das Material wurde anhand der qualitativen Inhaltsanalyse nach Mayring ausgewertet. Die Ergebnisse der Forschung zeigen auf, dass das Musikhören im Umgang mit psychischen Erkrankungen unterstützend wirkt. Im Alltag sowie im Verarbeiten von Gefühlen wird die Musik genutzt. Trotzdem ist das Musikhören als bedeutsame Tätigkeit im sozialpsychiatrischen Alltag unterrepräsentiert. Vorschläge für die sozialpädagogische Betreuung in der sozialpsychiatrischen Praxis beinhalten das Thematisieren von Musikpräferenzen in der Bezugspersonenarbeit, gemeinsames Musikhören mit anschliessender Reflexionsarbeit sowie das Durchführen von musikalischer Biografiearbeit in Einzelsettings. Diese Bachelorarbeit hat gezeigt, dass die Praxis durch das Thematisieren vom Musikhören stark profitieren kann.

description: Photoacoustic Remote Sensing (PARS) microscopy is an emerging label-free optical absorption imaging modality. PARS operates by capturing nanosecond-scale optical perturbations generated by photoacoustic pressures. These time-domain (TD) modulations are usually projected by amplitude to determine absorption magnitude. However, significant information on the target's material properties is contained within the TD signals. This work proposes a novel clustering method to learn TD features which relate to underlying biomolecule characteristics. This technique identifies features related to constituent biomolecules, enabling single-acquisition virtual tissue labelling. Colorized visualizations of tissue are produced, highlighting specific tissue components. This is demonstrated on freshly resected murine brain tissue, clearly discerning structures including myelinated and unmyelinated neurons (white and gray matter) and nuclear structures.

description: We have experimentally demonstrated an on-chip all-silk fibroin whispering gallery mode microresonator by using a simple molding and solution-casting technique. The quality factors of the fabricated silk protein microresonators are up to 10^5. A high-sensitivity thermal sensor was realized in this silk fibroin microtoroid with sensitivity of 1.17 nm/K, 8 times higher than previous WGM resonator based thermal sensors. This opens the way to fabricate biodegradable and biocompatible protein based microresonators on a flexible chip for biophotonics applications.

description: Dipole-coupled subwavelength quantum emitter arrays respond cooperatively to external light fields as they may host collective delocalized excitations (a form of excitons) with super- or subradiant character. Deeply subwavelength separations typically occur in molecular ensembles, where in addition to photon-electron interactions, electron-vibron couplings and vibrational relaxation processes play an important role. We provide analytical and numerical results on the modification of super- and subradiance in molecular rings of dipoles including excitations of the vibrational degrees of freedom. While vibrations are typically considered detrimental to coherent dynamics, we show that molecular dimers or rings can be operated as platforms for the preparation of long-lived dark superposition states aided by vibrational relaxation. In closed ring configurations, we extend previous predictions for the generation of coherent light from ideal quantum emitters to molecular emitters, quantifying the role of vibronic coupling onto the output intensity and coherence.
