description: We make phenomenological predictions for particle spectra and elliptic flow in heavy-ion collisions using 3+1d anisotropic hydrodynamics (aHydro) including the effects of both shear and bulk viscosities. The dynamical equations necessary are derived by taking moments of the Boltzmann equation allowing for three distinct (diagonal) momentum-space anisotropy parameters. The formulation is based on relaxation-time approximation for the collisional kernel and a lattice-QCD-based equation of state. Evolving the system to late times, we calculate particle production using THERMINATOR 2, modified to account for an ellipsoidal distribution function. We obtain particle spectra for different particle species such as pions, kaons, and protons, and elliptic flow $v_2$ as a function of centrality, transverse momentum, and rapidity. In our model, we have four free parameters, i.e. freeze-out temperature, initial central energy density, initial momentum-space anisotropies, and shear viscosity to entropy density ratio. Using a multidimensional fit to LHC experimental data, we make a preliminary extraction of these parameters. We find reasonable agreement between 3+1d aHydro and available experimental data for $η/s\sim 0.23$.

description: Transposable elements, or transposons, are DNA sequences that can jump from site to site in the genome during the life cycle of a cell, usually encoding the very enzymes which perform their excision. However, some transposons are parasitic, relying on the enzymes produced by the regular transposons. In this case, we show that a stochastic model, which takes into account the small copy numbers of the transposons in a cell, predicts noise-induced predator-prey oscillations with a characteristic time scale that is much longer than the cell replication time, indicating that the state of the predator-prey oscillator is stored in the genome and transmitted to successive generations. Our work demonstrates the important role of number fluctuations in the expression of mobile genetic elements, and shows explicitly how ecological concepts can be applied to the dynamics and fluctuations of living genomes.

description: Currently, the United States health care system is undergoing a transformation in health care delivery. Innovative strategies are needed to increase access to evidence-based mental health care and make progress on the goals of the health care “triple aim” of reducing per capita costs, improving health outcomes, and increasing patient satisfaction (Berwick, 2008 p. 760; McWilliams, 2016). Barriers including a shortage of mental health providers, lack of delivery infrastructure, state licensing limitations, and inconsistent insurance coverage must be addressed before telemental health can become viable. By 2025, social workers are anticipated to experience one of the largest shortages of the mental health provider types (Health Resources & Services Administration, 2016). Telehealth services have the potential to improve mental health care access, efficiency, and outcomes by reaching people who don’t seek treatment because of distance, cost of transportation, stigma, or disability, and by sharing clinical expertise and medical documentation to more people in less time. With decreasing costs and increasing acceptability by payers, providers, and patients, telehealth is more viable than ever before. Social workers are particularly well positioned to make use of telehealth opportunities because their training prepares them to work with individuals marginalized by issues such as stigma, disability, and socioeconomic status. To begin to address this gap in mental health care access, states should pass full parity laws for insurance coverage of telemedicine services so that social workers can provide care to clients regardless of where they are located.

description: Atom probe tomography is routinely used for the characterisation of materials microstructures usually assuming that the microstructure is unaltered by the analysis. When analysing ionic conductors, however, gradients in the chemical potential and the electric field penetrating dielectric atom probe specimens can cause significant ionic mobility. While ionic mobility is undesired when aiming for materials characterisation it offers a strategy to manipulate materials directly in-situ in the atom probe. Here, we present experimental results on the analysis of the ionic conductor Lithium-Manganese-Oxide with different atom probe techniques. We demonstrate that at a temperature of 30K characterisation of the materials microstructure is possible without measurable Li mobility. Contrary, we show that at 298K the material can be deintercalated in-situ in the atom probe without changing the Manganese-Oxide host structure. Combining in-situ atom probe deintercalation and subsequent conventional characterisation we demonstrate a new methodological approach to study ionic conductors even in early stages of deintercalation.

description: Time-resolved scattering experiments enable imaging of materials at the molecular scale with femtosecond time resolution. However, in disordered media they provide access to just one radial dimension thus limiting the study of orientational structure and dynamics. Here we introduce a rigorous and practical theoretical framework for predicting and interpreting experiments combining optically induced anisotropy and time-resolved scattering. Using impulsive nuclear Raman and ultrafast X-ray scattering experiments of chloroform and simulations, we demonstrate that this framework can accurately predict and elucidate both the spatial and temporal features of these experiments.

Publisher: name: Columbia Social Work Review
Year: 2019

description: Studies indicate that over 8.3 million children in the United States are exposed to domestic violence trauma, and results have indicated that exposure to this trauma can have serious developmental effects. This study includes qualitative data collection on six participants who have overcome childhood domestic violence trauma (CDVT). Each participant was interviewed, and successful coping strategies were identified in the process. Using Grounded Theory, which interprets the data into collective themes, coping strategies were put into categories and subcategories. After the strategies were organized, the results provided a structured framework for different coping alternatives that could be useful to practitioners who are working with people experiencing or recovering from CDVT in their lives. These results should be adhered to in curriculum-based practice, and can be used as a framework for macro, mezzo or micro application. Implications of this study include greater knowledge base for child welfare workers, along with the opportunity for new interventions in working with children struggling with CDVT. Furthermore, identification of these interventions can serve to reduce long-term effects of CDVT on children.

description: We perform a systematic study of the temporal dynamics emerging in the asymmetrically driven dissipative Bose-Hubbard dimer model. This model successfully describes the nonlinear dynamics of photonic diatomic molecules in linearly coupled Kerr resonators coherently excited by a single laser beam. Such temporal dynamics include self-pulsing oscillations, period doubled oscillatory states, chaotic dynamics, and spikes. The different states and dynamical regimes have been thoroughly characterized using bifurcation analysis. This analysis has allowed us to identify the main instabilities, i.e. bifurcations, responsible for the appearance of the previously stated dynamics.

Sie geht dabei der übergeordneten Fragestellung nach, wie aus Sicht der Kantone Angebote sozialer Einrichtungen adäquat für «Systemsprenger*innen» gestaltet werden könnten. Es werden die Ursachen, die kantonale Angebotsplanung, die Eigensicht der Betroffenen und günstige(re) Bedingungen im (kantonalen) Unterstützungs- und Versorgungssystem erörtert. Dazu werden die vorhandene Fachliteratur sowie die theoretischen Ansätze der Systemtheorie und der Lebensweltorientierung und Lebensbewältigung herangezogen. Auf Grundlage von leitfadengestützten qualitativen Interviews mit drei planungsverantwortliche Fachpersonen aus den Kantonen sowie zwei betroffenen Jugendlichen kann gezeigt werden, dass die Beschaffenheit der Kinder- und Jugendhilfesysteme grossen Einfluss auf die Situation der «Systemsprenger*innen» hat. Während die fachliche Haltung in den befragten Kantonen vorhanden ist, hinkt die Ausgestaltung der Systeme noch hinterher. Die Jugendlichen üben Systemkritik und fordern vor allem bessere Zukunftsperspektiven. Abschliessend werden mit der Einrichtung kantonaler Koordinationsstellen für schwierige Fallverläufe, der Erhöhung der Kooperation und Kommunikation und die Wahrnahme der Gestaltungsoptionen durch die Systeme konkrete Empfehlungen für die Praxis formuliert und Forschungsdesiderate benannt.

description: We present a numerical study of exciton-polariton (polariton) condensation in a staggered polariton graphene showing a gapped s-band at the $K$ and $K'$ valleys. The condensation occurs at $K$ or $K'$, at the kinetically-favorable negative mass extrema of the valence band. Considering attractive polariton-polariton interaction allows to generate a spatially extended condensate. Spontaneous symmetry breaking occurring during the condensate build-up leads to the formation of valley-polarized domains following the Kibble-Zurek scenario. The selection of a single valley breaks time-reversal symmetry and the walls separating domains exhibit a topologically-protected chiral current. This current therefore emerges as a result of the interplay between the non-trivial valley topology and the condensation-induced symmetry breaking.

description: We present OSIRIS/NAC observations of decimetre-sized, likely ice-containing aggregates ejected from a confined region on the surface of comet 67P/Churyumov-Gerasimenko. The images were obtained in January 2016 when the comet was at 2 AU from the Sun out-bound from perihelion. We measure the acceleration of individual aggregates through a two-hour image series. Approximately 50% of the aggregates are accelerated away from the nucleus, and 50% towards it, and likewise towards either horizontal direction. The accelerations are up to one order of magnitude stronger than local gravity, and are most simply explained by the combined effect of gas drag accelerating all aggregates upwards, and the recoil force from asymmetric outgassing, either from rotating aggregates with randomly oriented spin axes and sufficient thermal inertia to shift the temperature maximum away from an aggregate's subsolar region, or from aggregates with variable ice content. At least 10% of the aggregates will escape the gravity field of the nucleus and feed the comet's debris trail, while others may fall back to the surface and contribute to the deposits covering parts of the northern hemisphere. The rocket force plays a crucial role in pushing these aggregates back towards the surface. Our observations show the future back fall material in the process of ejection, and provide the first direct measurement of the acceleration of aggregates in the innermost coma (<2km) of a comet, where gas drag is still significant.

description: Im Rahmen der Fluchtbewegung als Reaktion auf den Ukrainekrieg kamen 2022 viele Geflüchtete bei Gastgebenden unter. Das Ziel dieser Bachelorarbeit ist es, den Einfluss des Lebens bei Gastgebenden auf das Ankommen der Geflüchteten in der Schweiz zu untersuchen. Entsprechend lautet die Forschungsfrage: Wie beschreiben die Geflüchteten aus der Ukraine den Einfluss der Gastgebenden im Sinne einer Ankommenshilfe in der Schweiz? Da es ein Anliegen war, explizit die Sichtweise der Geflüchteten abzubilden, wurden qualitative Interviews mit vier ukrainischen Frauen geführt, die 2022 mit ihren schulpflichtigen Kindern in die Schweiz geflüchtet sind. Es zeigt sich, dass die Unterbringung bei Gastgebenden grundsätzlich eine positive Auswirkung auf das Ankommen hat. Sowohl durch den Zugang zum sozialen Netzwerk der Gastgebenden, als auch Unterstützung bei Alltagsfragen, dem Spracherwerb oder bei Behördengängen können Gastgebende in der ersten Zeit und auch darüber hinaus förderlich sein. Gleichzeitig werden auch Risiken sichtbar, namentlich das bei einem Gastverhältnis vorhandene Machtgefälle, die Abhängigkeit von den Gastgebenden und damit verbundene Unsicherheit auf der Seite der Geflüchteten. Die Begegnung dieser Risiken auf nationaler Ebene mit einheitlichen fachlichen Standards könnte ein wichtiger Schritt für die Verbesserung von Gastverhältnissen darstellen und dadurch die Möglichkeit für Geflüchtete aus anderen Regionen der Welt öffnen.

description: It has been observed that the locally measured Hubble parameter converges quickest to the background value and the dipole structure of the velocity field is smallest in the reference frame of the Local Group of galaxies. We study the statistical properties of Lorentz boosts with respect to the Cosmic Microwave Background frame which make the Hubble flow look most uniform around a particular observer. We use a very large N-Body simulation to extract the dependence of the boost velocities on the local environment such as underdensities, overdensities, and bulk flows. We find that the observation is not unexpected if we are located in an underdensity, which is indeed the case for our position in the universe. The amplitude of the measured boost velocity for our location is consistent with the expectation in the standard cosmology.

description: We introduce new correlation consistent effective core potentials (ccECPs) for the elements I, Te, Bi, Ag, Au, Pd, Ir, Mo, and W with $4d$, $5d$, $6s$ and $6p$ valence spaces. These ccECPs are given as a sum of spin-orbit averaged relativistic effective potential (AREP) and effective spin-orbit (SO) terms. The construction involves several steps with increasing refinements from more simple to fully correlated methods. The optimizations are carried out with objective functions that include weighted many-body atomic spectra, norm-conservation criteria, and spin-orbit splittings. Transferability tests involve molecular binding curves of corresponding hydride and oxide dimers. The constructed ccECPs are systematically better and in a few cases on par with previous effective core potential (ECP) tables on all tested criteria and provide a significant increase in accuracy for valence-only calculations with these elements. Our study confirms the importance of the AREP part in determining the overall quality of the ECP even in the presence of sizable spin-orbit effects. The subsequent quantum Monte Carlo (QMC) calculations point out the importance of accurate trial wave functions which in some cases (mid series transition elements) require treatment well beyond single-reference.

description: Problem-based visualization research provides explicit guidance toward identifying and designing for the needs of users, but absent is more concrete guidance toward factors external to a user's needs that also have implications for visualization design and evaluation. This lack of more explicit guidance can leave visualization researchers and practitioners vulnerable to unforeseen constraints beyond the user's needs that can affect the validity of evaluations, or even lead to the premature termination of a project. Here we explore two types of external constraints in depth, regulatory and organizational constraints, and describe how these constraints impact visualization design and evaluation. By borrowing from techniques in software development, project management, and visualization research we recommend strategies for identifying, mitigating, and evaluating these external constraints through a design study methodology. Finally, we present an application of those recommendations in a healthcare case study. We argue that by explicitly incorporating external constraints into visualization design and evaluation, researchers and practitioners can improve the utility and validity of their visualization solution and improve the likelihood of successful collaborations with industries where external constraints are more present.

description: Frequency-resolved optical gating (FROG) is probably the most popular technique for complete characterization of ultrashort laser pulses. In FROG, a reconstruction algorithm retrieves the pulse from a measured spectrogram, yet current FROG reconstruction algorithms require and exhibit several restricting features that weaken FROG performances. For example, the delay step must correspond to the spectral bandwidth measured with large enough SNR a condition that limits the temporal resolution of the reconstructed pulse, obscures measurements of weak broadband pulses, and makes measurement of broadband mid-IR pulses hard and slow because the spectrograms become huge. We develop a new approach for FROG reconstruction, based on ptychography (a scanning coherent diffraction imaging technique), that removes many of the algorithmic restrictions. The ptychographic reconstruction algorithm is significantly faster and more robust to noise than current FROG algorithms, which are based on generalized projections (GP). We demonstrate, numerically and experimentally, that ptychographic reconstruction works well with very partial spectrograms, e. g. spectrograms with reduced number of measured delays and spectrograms that have been substantially spectrally filtered. In addition, we implement the ptychogrpahic approach to blind second harmonic generation (SHG) FROG and demonstrate robust and complete characterization of two unknown pulses from a single measured spectrogram and power spectrum of only one of the pulses. We believe that the ptychograpy-based approach will become the standard reconstruction procedure in FROG and related diagnostics methods, allowing successful reconstructions from so far unreconstructable spectrograms.

description: Nonequilibrium dynamics is a paramount scenario for studying quantum systems. The emergence of new features with no equilibrium counterpart, such as dynamical quantum phase transition (DQPT), has attracted wide attention. In this work, we depart from the well known Ising model and showcase an experimentally accessible configuration of a negatively charged Nitrogen-Vacancy center that interacts with nearby Carbon-13 nuclear spins. We provide new insights into this system in the context of DQPT. We show that nuclear spins undergo DQPT by appropriately choosing the relation between the transverse and longitudinal components of an external magnetic field. Furthermore, we can steer the DQPT via a time-dependent longitudinal magnetic field and apply this control to enhance the estimation of the coupling strength between the nuclear spins. Moreover, we propose a novel quenched dynamics that originates from the rotation of the central electron spin, which controls the DQPT relying on the anisotropy of the hyperfine coupling.

description: The SEAwise project works to deliver a fully operational tool that will allow fishers, managers, and policy makers to easily apply Ecosystem Based Fisheries Management (EBFM) in their own fisheries. This report describes the SEAwise guidelines for estimating uncertainty and the predictive capability of models; key components of the SEAwise Output Quality Assurance Process. In the project, all data and models are evaluated using this Quality Assurance Process. These guidelines were developed through a review of the published scientific literature and in consultation with SEAwise partners, members of the larger scientific community, and interested stakeholders. The guidelines are intended to support the collaborative use and development of the best available scientific tools that are fit for purpose for ecosystem-based fisheries management. As project partners work with the guidelines throughout the SEAwise regions, it is expected that the guidelines will be further developed and articulated. The guidelines are not meant to be prescriptive but rather to be used as a basic framework that specifies acceptable risk levels to ensure that predictive models are placed in the sweet spot where model complexity maximises predictive ability in a manner that works for both the developers and end users.

description: Women who were formerly incarcerated face a number of interrelated inequities and challenges on community reentry, which leads to poor social- emotional outcomes and increases risk of recidivism. These problems, which are compounded for women of color who have been formerly incarcerated and which are ultimately deleterious to individuals, communities, and the economy, are inadequately addressed by micro-level direct-service delivery and traditional solutions like governmental initiatives and nonprofitorganizations. Because governmental initiatives and nonpro t organizations have become ine cient and ine ective in providing solutions to complexsocial problems, it has become imperative for social work professionals to investigate alternatives to achieve transformational change for individuals and communities. This paper contends that social enterprise is an emerging alternative best positioned to address complex challenges faced by women who have been formerly incarcerated, especially in mitigating barriers to employment and economic mobility.

The Forest and the Trees
Creators: name: Segal, Erin
Publisher: name: Columbia Social Work Review

description: Social work education gives lip service to systems-based, integrative approaches to practice, yet the profession tends to create unnecessary polarities between clinical practice and social work’s original commitment to vulnerable populations, person-in-environment, and social change. The author describes a model of community-based family services that bridges this gap.

Einflussfaktoren auf die Sozialhilfequote: Eine vergleichende Studie zu den Einflussfaktoren auf die Sozialhilfequote der Städte Biel und Winterthur.
Creators: name: Baumgartner, Sophie
Publisher: name: Zenodo

description: Im Rahmen dieser Bachelorarbeit wird der Frage nachgegangen, welche Faktoren die Sozialhilfequoten von Biel und Winterthur beeinflussen. Biel weist mit einer Sozialhilfequote von 10.2% einen wesentlich höheren Anteil als Winterthur mit 5.5% auf. Die vorliegende quantitativ vergleichende Studie der beiden Städte, gab Aufschluss über relevante Einflussfaktoren. Hierfür wurden Daten der beiden Städte aus den Bereichen räumliche-Typologie, Bevölkerungsstruktur, Wirtschaft und Politik zusammengetragen und miteinander verglichen. Anschliessend wurden Streudiagramme und die Korrelationskoeffizienten berechnet. Zur Validierung der Ergebnisse wurden Interviews mit Fachpersonen im Bereich Wirtschaft und sozialer Probleme geführt. Anhand der Analysen konnte die erhebliche Komplexität der Einflüsse sichtbar gemacht werden. Die Ergebnisse lassen vermuten, dass zum einen ein niedriger Bildungsstand, zum anderen eine hohe Leerwohnungsziffer mit niedrigen Mietzinsen, sowie ein hoher Anteil von nicht-europäischer Bevölkerungsanteil, und insbesondere einer Minimierung der Stigmatisierung wirtschaftlicher Sozialhilfe, eine erhöhte Sozialhilfequote der Stadt Biel zur Folge haben. Wohingegen aus den Ergebnissen geschlossen werden konnte, dass eine wachsende Wirtschaftsregion, wie sie in der Stadt Winterthur vorhanden ist, sich positiv auf die Sozialhilfequote auswirkt. Die Ergebnisse deuten zusätzlich darauf hin, dass Normen und Werte den Nichtbezug von wirtschaftlicher Hilfe beeinflussen und letztlich die Sozialhilfequote bedeutend beeinflussen könnten.

The extended states in disordered 1D systems in the presence of the generalized $N$-mer correlations
Creators: name: Major, Jan

Year: 2016
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We have been investigating the problem of the Anderson localization in a disordered one dimensional tight-binding model. The disorder is created by the interaction of mobile particles with other species, immobilized at random positions. We introduce a novel method of creating correlations in the optical lattices with such a kind of disorder by using two different lattices with commensurate lattice lengths to hold two species of the particles. Such a model, called the generalized random $N$-mer model leads to the appearance of multiple extended states in contrary to a localization of all states usually expected in one dimension. We develop a method, based on properties of transfer matrices which can be used to determine the presence of extended states and their energies for that class of correlations. Analytical results are compared with the numerical calculations for several cases which can be realized in cold-atom experiments.

description: South Asians are one of the fastest growing immigrant groups in the United States. This paper identifies possible reasons why South Asians in the U. S. under-utilize mental health services compared to other immigrant communities, and offers suggestions regarding how mental health services can be tailored to better meet the needs of this particular ethnic group.

Boosting jittering jets by neutrino heating in core collapse supernovae
Creators: name: Soker, Noam
Publisher: name: arXiv

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: I estimate the energy that neutrino heating adds to the outflow that jets induce in the collapsing core material in core collapse supernovae (CCSNe), and find that this energy crudely doubles the energy that the jets deposit into the outer core. I consider the jittering jets explosion mechanism where there are several stochastic jet-launching episodes, each lasting for about 0.01-0.1 seconds. The collapsing core material passes through the stalled shock at about 100 km and then slowly flows onto the proto-neutron star (NS). I assume that the proto-NS launches jittering jets, and that the jets break out from the stalled shock. I examine the boosting process by which the high-pressure gas inside the stalled shock, the gain region material, expands alongside the jets and does work on the material that the jets shock, the cocoon. This work is crudely equal to the energy that the original jets carry. I argue that the coupling between instabilities, stochastic rotation, magnetic fields, and jittering jets lead to most CCSN explosions. In other cases, the pre-collapse core is rapidly rotating and therefore ordered rotation replaces stochastic rotation and fixed jets replace jittering jets.

description: Feature selection is an important task in many problems occurring in pattern recognition, bioinformatics, machine learning and data mining applications. The feature selection approach enables us to reduce the computation burden and the falling accuracy effect of dealing with huge number of features in typical learning problems. There is a variety of techniques for feature selection in supervised learning problems based on different selection metrics. In this paper, we propose a novel unified framework for feature selection built on the graphical models and information theoretic tools. The proposed approach exploits the structure learning among features to select more relevant and less redundant features to the predictive modeling problem according to a primary novel likelihood based criterion. In line with the selection of the optimal subset of features through the proposed method, it provides us the Bayesian network classifier without the additional cost of model training on the selected subset of features. The optimal properties of our method are established through empirical studies and computational complexity analysis. Furthermore the proposed approach is evaluated on a bunch of benchmark datasets based on the well-known classification algorithms. Extensive experiments confirm the significant improvement of the proposed approach compared to the earlier works.

description: Mercurial policy shifts concerning the gender identity and sexual orientation of individuals serving in the United States military haveadversely a ected the quality of health care o ered to service members whoidentify as lesbian, gay, bisexual, transgender, or queer (LGBTQ) directly impacting unit readiness. A lack of LGBTQ-affirming services within the military health care system compromises the health and well-being of LGBTQ service members, which is symptomatic of the exclusionary, heteronormative culture fostered by decades of discriminatory policy. The historic inequity within the military and its impact on the relationship between LGBTQ service members and military health care providers (MHCPs) must be addressed to rectify the ongoing health care disparity.Moreover, policies and LGBTQ-a rming practices that empower servicemembers and foster inclusivity must be implemented to strengthen the military as a whole.

Social Workers of the World Unite
Creators: name: Buck, Lesley
Publisher: name: Columbia Social Work Review
Year: 2019

description: Social workers begin their professional careers in graduate school. In preparation, students need to educate themselves with regard to relevant social and political issues. The NASW Code of Ethics stresses the profession’s ethical obligation to actively work on behalf of the goals of social justice and social change. Graduate social work programs fall short of preparing students for the progressive role the profession requires. Social workers are uniquely positioned to converge various fields relevant to social change. Furthermore, social work is a political activity, as it either serves the status quo or the concerns of client populations. Students are required to reconcile the ethics of the profession and their graduate training through engaging in political and social action.

Schutzstatus S – Eine Ungleichbehandlung im Schweizer Asylwesen? Eine Analyse der Ungleichbehandlung geflüchteter Personen aus postkolonialer und normativ-ethischer Perspektive im Kontext des Professionsmandats der Sozialen Arbeit

description: Die Ukrainer:innen waren aufgrund der russischen Invasion im Februar 2022 gezwungen, ihre Heimat zu verlassen. Die grösste Fluchtbewegung seit dem zweiten Weltkrieg stellte das Schweizer Asylwesen vor eine Herausforderung. Die Schweiz aktivierte deshalb zum ersten Mal den Schutzstatus S, der eine schnelle und unkomplizierte Aufnahme ukrainischer Geflüchteter ermöglicht. Diese Ausgangslage repräsentiert eine Ungleichbehandlung im Asylwesen, da anderen Geflüchteten diese Privilegierung nicht zukommt. Aufgrund des Tripelmandats ist die Soziale Arbeit verpflichtet, Flucht als soziales Problem zu thematisieren. Diese Bachelorarbeit legt den Fokus auf die Erklärung und Beurteilung der beschriebenen Ungleichbehandlung im Schweizer Asylwesen. Dazu wird die postkoloniale Theorie sowie die normative Ethik herangezogen. Die postkoloniale Theorie befasst sich mit den langfristigen Auswirkungen des Kolonialismus, die normative Ethik dient dazu, die Handlungen der Schweizer Asylpolitik kritisch zu betrachten. Anhand des Professionsmandats erfolgt daraus eine kritische Diskussion. Die Ungleichbehandlung im Schweizer Asylwesen beruht auf postkolonialen Strukturen. Zudem zeigt die normativ-ethische Analyse, dass die Handlungen im Schweizer Asylwesen ethisch nicht vertretbar sind. Die Soziale Arbeit ist demnach verpflichtet, diese Ungerechtigkeiten zurückzuweisen und Veränderungen einzufordern.
