description: Kommunikation findet täglich statt und ist etwas Selbstverständliches. Es gehört zu den Menschenrechten und Grundbedürfnissen, welche allerdings nicht für alle Menschen gleich zugänglich sind. Menschen mit Komplexer Behinderung können sich aufgrund meist stark eingeschränkter kommunikativer Fähigkeiten oft nicht ausreichend mitteilen. Im stationären Setting sind sie auf die Unterstützung der Betreuungspersonen angewiesen, um in ihrer Kommunikation wahrgenommen und verstanden zu werden. In dieser Bachelor-Arbeit wird auf die Gestaltung der Kommunikation zwischen Erwachsenen mit Komplexer Behinderung und Betreuungspersonen eingegangen. Die Verfasserinnen Melinda Flückiger und Jasmin Wyss erforschen, welche förderlichen Faktoren sich für eine gelingende Kommunikation für die Praxis mit Erwachsenen mit Komplexer Behinderung im stationären Setting ergeben. Für die Beantwortung wurde zunächst auf Erwachsenen mit Komplexer Behinderung und die Kommunikation von und mit ihnen eingegangen. Anschliessend wurden mittels qualitativer Forschung Fachpersonen der Sozialpädagogik oder Betreuung nach ihren Erfahrungen in der Kommunikation mit Erwachsenen mit Komplexer Behinderung befragt. Die daraus resultierenden Erkenntnisse wurden mit der Theorie in Zusammenhang gebracht. Auf diese Weise konnten förderliche Faktoren für eine gelingende Kommunikation mit Erwachsenen mit Komplexer Behinderung in den Bereichen der Betreuungspersonen, der Institution und des Sozialraums eruiert werden. Es lässt vermuten, dass es ein grösseres Bewusstsein über die Bedeutung der Kommunikation und Wissen darüber benötigt, wie die Kommunikation bei Erwachsenen mit Komplexer Behinderung gefördert werden kann.

description: The spin magnetic dipole transitions and the neutron-proton spin-spin correlations in $sd-$shell even-even nuclei with $N=Z$ are investigated using shell model wave functions. The isoscalar spin-triplet pairing correlation provides a substantial quenching effect on the spin magnetic dipole transitions, especially the isovector (IV) ones. Consequently, an enhanced isoscalar spin-triplet pairing interaction influences the proton-neutron spin-spin correlation deduced from the difference between the isoscalar (IS) and the IV sum rule strengths. The effect of the $Δ$ ($Δ_{33}$ resonance)-hole coupling is examined in the IV spin transition and the spin-spin correlations of the ground states.

description: K2-141 b is a transiting, small (1.5 Re) ultra-short-period (USP) planet discovered by Kepler orbiting a K-dwarf host star every 6.7 hours. The planet's high surface temperature makes it an excellent target for thermal emission observations. Here we present 65 hours of continuous photometric observations of K2-141 b collected with Spitzer's IRAC Channel 2 at 4.5 micron spanning 10 full orbits of the planet. We measure an infrared eclipse depth of 143 +/- 39 ppm and a peak to trough amplitude variation of 121 +/- 43 ppm. The best fit model to the Spitzer data shows no significant thermal hotspot offset, in contrast to the previously observed offset for the well-studied USP planet 55 Cnc e. We also jointly analyze the new Spitzer observations with the photometry collected by Kepler during two separate K2 campaigns. We model the planetary emission with a range of toy models that include a reflective and a thermal contribution. With a two-temperature model, we measure a dayside temperature of 2049 +/- 361 K and a night-side temperature that is consistent with zero (Tp,n < 1712 K at 2 sigma). Models with a steep dayside temperature gradient provide a better fit to the data than a uniform dayside temperature (DeltaBIC = 22.2). We also find evidence for a non-zero geometric albedo Ag = 0.28 +/- 0.07. We also compare the data to a physically motivated, pseudo-2D rock vapor model and a 1D turbulent boundary layer model. Both models fit the data well. Notably, we find that the optical eclipse depth can be explained by thermal emission from a hot inversion layer, rather than reflected light. A thermal inversion may also be responsible for the deep optical eclipse observed for another USP, Kepler-10 b. Finally, we significantly improve the ephemerides for K2-141 b and c, which will facilitate further follow-up observations of this interesting system with state-of-the-art observatories like JWST.

description: Entropy plays a key role in statistical physics of complex systems, which in general exhibit diverse aspects of emergence on different scales. However, it still remains not fully resolved how entropy varies with the coarse-graining level and the description scale. In this paper, we consider a Yule-type growth model, where each element is characterized by its size being either continuous or discrete. Entropy is then defined directly from the probability distribution of the states of all elements as well as from the size distribution of the system. Probing in detail their relations and time evolutions, we find that heterogeneity in addition to correlations between elements could induce loss of information during the coarse-graining procedure. It is also revealed that the expansion of the size space domain depends on the description level, leading to a difference between the continuous description and the discrete one.

description: Der demografische Wandel und technologische Fortschritte sind nicht aufzuhalten und werden die Gesellschaft nachhaltig verändern. Zu den zentralen Themen gehören dabei die Alterung der Bevölkerung und immersive Technologien, zu welchen die Virtuelle Realität zählt. Das Ziel der vorliegenden Bachelor-Arbeit «Immersive Technologien in der soziokulturellen Altersarbeit» ist es zu beantworten, wie immersive Technologien in der soziokulturellen Altersarbeit zielführend eingesetzt werden können. Dazu wird die Forschungsfrage gestellt: «Welche Chancen und Risiken bietet die Digitalisierung, speziell immersive Technologien, älteren Menschen?». Um die Forschungsfrage zu beantworten, wurde eine qualitative Forschung anhand von Expert*innen-Interviews durchgeführt. Dabei wurden drei Expert*innen interviewt, die sich im Feld der Digitalisierung oder der Altersarbeit in Bezug auf die Soziale Arbeit auskennen. Die Ergebnisse aus den Interviews wurden mit den zuvor gesammelten Theoriebezügen in Zusammenhang gebracht und diskutiert, was diese für die Soziale Arbeit speziell die Soziokulturelle Animation in Zukunft bedeuten wird. Die Virtuelle Realität bietet gemäss den Erkenntnissen grosse Chancen, die Teilhabe zu erhöhen und der Einsamkeit vorzubeugen. Sie ist aber auch mit Risiken wie den benötigten digitalen Kompetenzen sowie dem Datenschutz verbunden. Die professionellen der Soziale Arbeit, insbesondere die Soziokulturelle Animation, bewegt sich in den Lebensrealitäten ihrer Adressat*innen und ist daher gefordert, sich mit den zukünftigen Entwicklungen gerade auch in Bezug auf ältere Menschen auseinander zu setzen, um den Wandel mitzugestalten.

description: The Muon g-2 Experiment at Fermilab will measure the anomalous magnetic moment of the muon to a precision of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. The experiment will also extend the search for the electric dipole moment (EDM) of the muon by approximately two orders of magnitude, with a sensitivity down to $10^{-21}$ e.cm. Both of these measurements are made by combining a precise measurement of the 1.45T storage ring magnetic field with an analysis of the modulation of the decay rate of higher-energy positrons (from anti-muons), recorded by 24 calorimeters and 3 straw tracking detectors. The recent progress in the alignment of the electrostatic quadrapole plates and the trolley rails inside the vacuum chambers, and in establishing the uniform storage ring magnetic field will be described.

description: Recently, a hypothesis on the complexity growth of unitarily evolving operators was presented. This hypothesis states that in generic, non-integrable many-body systems the so-called Lanczos coefficients associated with an autocorrelation function grow asymptotically linear, with a logarithmic correction in one-dimensional systems. In contrast, the growth is expected to be slower in integrable or free models. In the paper at hand, we numerically test this hypothesis for a variety of exemplary systems, including 1d and 2d Ising models as well as 1d Heisenberg models. While we find the hypothesis to be practically fulfilled for all considered Ising models, the onset of the hypothesized universal behavior could not be observed in the attainable numerical data for the Heisenberg model. The proposed linear bound on operator growth eventually stems from geometric arguments involving the locality of the Hamiltonian as well as the lattice configuration. We investigate such a geometric bound and find that it is not sharply achieved for any considered model.

description: The formation of supermassive stars (SMSs) via rapid mass accretion and their direct collapse into black holes (BHs) is a promising pathway for sowing seeds of supermassive BHs in the early universe. We calculate the evolution of rapidly accreting SMSs by solving the stellar structure equations including nuclear burning as well as general relativistic (GR) effects up to the onset of the collapse. We find that such SMSs have less concentrated structure than fully-convective counterpart, which is often postulated for non-accreting ones. This effect stabilizes the stars against GR instability even above the classical upper mass limit $\gtrsim 10^5~M_\odot$ derived for the fully-convective stars. The accreting SMS begins to collapse at the higher mass with the higher accretion rate. The collapse occurs when the nuclear fuel is exhausted only for cases with $\dot M \lesssim 0.1~M_\odot~{\rm yr}^{-1}$. With $\dot{M} \simeq 0.3 - 1~M_\odot~{\rm yr}^{-1}$, the star becomes GR-unstable during the helium-burning stage at $M \simeq 2 - 3.5~\times 10^5~M_\odot$. In an extreme case with $10~M_\odot~{\rm yr}^{-1}$, the star does not collapse until the mass reaches $\simeq 8.0\times 10^5~M_\odot$, where it is still in the hydrogen-burning stage. We expect that BHs with roughly the same mass will be left behind after the collapse in all the cases.

description: As the field of optomechanics advances, quadratic dispersive coupling (QDC) promise an increasingly feasible class of qualitatively new functionality. However, the leading QDC geometries also generate linear dissipative coupling, and an associated quantum radiation force noise that is detrimental to QDC applications. Here, we propose a simple modification that dramatically reduces this noise without altering the QDC strength. We identify optimal regimes of operation, and discuss advantages within the examples of optical levitation and nondestructive phonon measurement.

description: Die vorliegende Bachelorarbeit thematisiert die Nutzung sozialer Netzwerke von Jugendlichen mit kognitiven Beeinträchtigungen. Um die Vorteile der sozialen Netzwerke zu nutzen und Risiken richtig einschätzen zu können, ist es von Bedeutung, die Jugendlichen mit kognitiven Beeinträchtigungen zu befähigen, sich souverän in der digitalen Welt zu bewegen. So ist auch die Sozialpädagogik im Kontext der Separativen Sonderschulung gefordert, sich mit digitalen Medien und der Nutzung sozialer Netzwerke aus einer medienpädagogischen Perspektive auseinanderzusetzen. Die Autor*innen Eva Frey und Ruben Gnos befassen sich deshalb mit der Frage: «Wie können Sozialpädagog*innen Jugendliche mit kognitiven Beeinträchtigungen an Separativen Sonderschulen im Umgang mit Risiken sozialer Netzwerke adäquat begleiten und aufklären?». In einem ersten Schritt wird eine breite Auslegeordnung der relevanten Aspekte der Thematik dargelegt. Die Bedeutung der Nutzung sozialer Netzwerke wird beschrieben und es wird aufgezeigt, dass die digitale Teilhabe Voraussetzung für gesellschaftliche Teilhabe darstellt. Ausserdem werden gesetzliche Bestimmungen beleuchtet, welche die digitale Teilhabe von Jugendlichen mit kognitiven Beeinträchtigungen auf internationaler und nationaler Ebene einfordern. Danach folgt eine Beschreibung von zentralen Chancen und Risiken in der Nutzung sozialer Netzwerke. Darauf aufbauend werden Herausforderungen der Medienbildung in der Praxis auf individueller und organisationaler Ebene und Lösungsansätze aus der Theorie vorgestellt. Daraus entstehen greifbare Handlungsvorschläge für Sozialpädagog*innen wie auch weiterführende Fragen im Zusammenhang mit dieser Thematik.

description: Semantic segmentation using convolutional neural networks (CNNs) is the state-of-the-art for many medical image segmentation tasks including myocardial segmentation in cardiac MR images. However, the predicted segmentation maps obtained from such standard CNN do not allow direct quantification of regional shape properties such as regional wall thickness. Furthermore, the CNNs lack explicit shape constraints, occasionally resulting in unrealistic segmentations. In this paper, we use a CNN to predict shape parameters of an underlying statistical shape model of the myocardium learned from a training set of images. Additionally, the cardiac pose is predicted, which allows to reconstruct the myocardial contours. The integrated shape model regularizes the predicted contours and guarantees realistic shapes. We enforce robustness of shape and pose prediction by simultaneously performing pixel-wise semantic segmentation during training and define two loss functions to impose consistency between the two predicted representations: one distance-based loss and one overlap-based loss. We evaluated the proposed method in a 5-fold cross validation on an in-house clinical dataset with 75 subjects and on the ACDC and LVQuan19 public datasets. We show the benefits of simultaneous semantic segmentation and the two newly defined loss functions for the prediction of shape parameters. Our method achieved a correlation of 99% for left ventricular (LV) area on the three datasets, between 91% and 97% for myocardial area, 98-99% for LV dimensions and between 80% and 92% for regional wall thickness.

description: In this paper, we consider the Bianchi type-I space-time with perfect fluid as matter content of the Universe in the framework of $f(Q)$ gravity (where $% Q$ is the non-metricity scalar) recently proposed by Jiménez et al. (Phys. Rev. D 98.4 (2018): 044048). We find exact solutions of the field equations using the anisotropic property of space-time for volumetric hybrid expansion. The cosmological parameters for the linear form of non-metricity scalar i.e. $f\left( Q\right) =αQ+β$ (where $α$ and $β$ are free model parameters) are discussed and compared with recent Hubble measurements. Also, we have obtained the best fitting values of the model parameters $k, n$ and $H_{0}$ by constraining our model with updated Hubble datasets consisting of 57 data points ($31$ (DA) and $26$ (BAO+other)) along with also examined the stability of the model and test its validity by energy conditions.

description: Quasiparticle interference (QPI) imaging of Bogoliubov excitations in quasi-two dimensional unconventional superconductors has become a powerful technique for measuring the superconducting gap and its symmetry. Here, we present the extension of this method to three-dimensional superconductors and analyze the expected QPI spectrum for the two-component heavy fermion superconductor UPt$_3$ whose gap structure is still controversial. Starting from a 3D electronic structure and the three proposed chiral gap models $E_{1g,u}$ or $E_{2u}$, we perform a slab calculation that determines the 2D continuum Bogoliubov- de Gennes (BdG) surface quasiparticle bands and in addition the in-gap flat-band Andreev bound states that lead to surface Weyl arcs connecting the projected gap nodes. Both features are very distinct for the three models, in particular the most prominent $E_{2u}$ candidate is singled out by the existence of {\it two} Weyl arcs due to the double monopole node points. The signature of these distinct surface bound and continuum states that is left in QPI is derived and discussed. We show that it provides a fingerprint that may finally determine the true nodal structure of UPt$_3$ superconductor.

description: Die vorliegende Bachelorarbeit beschäftigt sich mit der Frage, inwiefern die Bedürfnisse von Sozialhilfebeziehenden mit den Interessen von Sozialdiensten übereinstimmen. Während Sozialhilfebeziehende den Herausforderungen des Zwangskontextes und knappen finanziellen Mitteln gegenüberstehen, sind Sozialdienste durch hohe Fallzahlen und strukturelle Rahmenbedingungen des Systems herausgefordert. Um einen fundierten Einblick in die Thematik zu erhalten, wird einleitend der Auftrag der wirtschaftlichen Sozialhilfe, Organisationformen von Sozialdiensten, sowie die Zielgruppe und Fallentwicklung erläutert. Anschliessend wird die Profession Soziale Arbeit näher beleuchtet, wie auch die Bedürfnistheorien von Abraham Maslow und Klaus Grawe. Basierend auf genanntem Wissensstand, wurden zwei quantitative und qualitative Datenerhebungen mittels Online-Befragung - eine bei Sozialhilfebeziehenden und eine bei Sozialarbeitenden auf Sozialdiensten – im Kanton Zürich durchgeführt. Dabei ging es einerseits darum zu erforschen, welche Bedürfnisse Sozialhilfebeziehende haben und andererseits, welche Spannungsfelder zwischen diesen und den Interessen von Sozialdiensten bestehen. Die Ergebnisse wurden in Verbindung mit der theoretischen Fundierung und Profession, reflektiert. Die Ergebnisse zeigten eine hohe Zufriedenheit von Seiten Sozialhilfebeziehenden gegenüber Sozialarbeitenden und gleichzeitig, dass sie in den Bereichen «Finanzielles», «Soziales» und «Wohnen», mehr Unterstützung wünschen. Die Bachelorarbeit schliesst mit herausgearbeiteten Handlungsempfehlungen für Sozialdienste und beruflichen Schlussfolgerungen für Sozialarbeitende, einem Ausblick und Dank, ab.

description: M54 is a prototype of a globular cluster embedded in a dark matter halo. Gaia EDR3 photometry and proper motions separate the old, metal-poor stars from the more metal rich and younger dwarf galaxy stars. The metal poor stars dominate the inner 50 pc, with a velocity dispersion profile that declines to a minimum around 30 pc then rises back to nearly the central velocity dispersion, as expected for a globular cluster at the center of a dark matter halo. The Jeans analysis of the three separate stellar populations give consistent masses that rise approximately linearly with radius to 1 kpc, implying a small core or cuspy halo. These data are compatible with an infalling CDM dark matter halo reduced to 3x10^8 M_sun at the 50 kpc apocenter 2.3 Gyr ago, with a central globular cluster surrounded by the remnant of a dwarf galaxy. Tides gradually remove material beyond 1 kpc but have little effect on the stars and dark matter within 300 pc of the center. M54 appears to be a transitional system between globular clusters with and without local dark halos, whose evolution within the galaxy depends sensitively on the time of accretion and orbital pericenter.

description: We present concrete embeddings of fibre inflation models in globally consistent type IIB Calabi-Yau orientifolds with closed string moduli stabilisation. After performing a systematic search through the existing list of toric Calabi-Yau manifolds, we find several examples that reproduce the minimal setup to embed fibre inflation models. This involves Calabi-Yau manifolds with $h^{1,1}= 3$ which are K3 fibrations over a $\mathbb{P}^1$ base with an additional shrinkable rigid divisor. We then provide different consistent choices of the underlying brane set-up which generate a non-perturbative superpotential suitable for moduli stabilisation and string loop corrections with the correct form to drive inflation. For each Calabi-Yau orientifold setting, we also compute the effect of higher derivative contributions and study their influence on the inflationary dynamics.

description: We study a system of coupled phase oscillators near a saddle-node on an invariant circle bifurcation and driven by random intrinsic frequencies. Under the variation of control parameters, the system undergoes a phase transition changing the qualitative properties of collective dynamics. Using the Ott-Antonsen reduction and geometric techniques for ordinary differential equations, we identify a heteroclinic bifurcation in a family of vector fields on a cylinder, which explains the change in collective dynamics. Specifically, we show that the heteroclinic bifurcation separates two topologically distinct families of limit cycles: contractible limit cycles before the bifurcation from noncontractibile ones after the bifurcation. Both families are stable for the model at hand.

description: Giant molecular clouds contain supersonic turbulence that can locally heat small fractions of gas to over 100 K. We run shock models for low-velocity, C-type shocks propagating into gas with densities between 10^3 and 10^5 cm^(-3) and find that CO lines are the most important cooling lines. Comparison to photodissociation region (PDR) models indicates that mid-J CO lines (J = 8-7 and higher) should be dominated by emission from shocked gas. In Papers I and II we presented CO J = 3-2, 8-7, and 9-8 observations toward four primarily quiescent clumps within infrared dark clouds. Here we fit PDR models to the combined spectral line energy distributions and show that the PDR models that best fit the low-J CO emission underpredict the mid-J CO emission by orders of magnitude, strongly hinting at a hot gas component within these clumps. The low-J CO data clearly show that the integrated intensities of both the CO J = 8-7 and 9-8 lines are anomalously high, such that the line ratio can be used to characterize the hot gas component. Shock models are reasonably consistent with the observed mid-J CO emission, with models with densities near 10^(4.5) cm^(-3) providing the best agreement. Where this mid-J CO is detected, the mean volume filling factor of the hot gas is 0.1%. Much of the observed mid-J CO emission, however, is also associated with known protostars and may be due to protostellar feedback.

Seit dem Bundesgerichtsentscheid 145 V 215 von 2019 hat sich die Beurteilung des Anspruchs auf Leistungen bei Vorliegen einer Abhängigkeitserkrankung geändert. Neu sind fachärztlich diagnostizierte Abhängigkeitserkrankungen grundsätzlich als invalidisierende Gesundheitsschäden zu beachten. Die vorliegende Bachelorarbeit der Autorin Milena Furrer mit dem Titel «Aktuelle Situation von Menschen mit einer Abhängigkeitserkrankung hinsichtlich der Geltendmachung des Anspruchs auf Eingliederungsmassnahmen und Renten der Invalidenversicherung» befasst sich in einem theoretischen Teil mit der Abhängigkeitserkrankung, bezieht dann methodische Aspekte der Sozialberatung mit ein und zeigt schliesslich die Grundlagen der Invalidenversicherung und der neuen Rechtsprechung auf. Trotz der neuen Rechtsprechung existieren Zweifel gegenüber der Umsetzung des neuen Rechts. Aus diesem Grund wurde mit leitfadengestützten Experteninterviews die aktuelle Situation von Menschen mit einer Abhängigkeitserkrankung bei der Geltendmachung von Ansprüchen gegenüber der Invalidenversicherung untersucht. Die Studie zeigte, dass in verschiedenen Bereichen immer noch Bedingungen existieren, welche die Geltendmachung der Ansprüche erschweren. Die aktuelle Praxis anerkennt den Krankheitswert der Abhängigkeitserkrankung nur bedingt: Sei es in der Erfüllung der Mitwirkungsplicht, oder dass im Namen der Schadensminderungspflicht immer noch Auflagen angeordnet werden, die sich am Abstinenzparadigma orientieren und dem aktuellen medizinischen Wissen widersprechen.

description: The properties of hydrogen under extreme conditions are important for many applications, including inertial confinement fusion and astrophysical models. A key quantity is given by the electronic density response to an external perturbation, which is probed in X-ray Thomson scattering (XRTS) experiments -- the state of the art diagnostics from which system parameters like the free electron density $n_e$, the electronic temperature $T_e$, and the charge state $Z$ can be inferred. In this work, we present highly accurate path integral Monte Carlo (PIMC) results for the electronic density response of hydrogen. We obtain the exchange-correlation (XC) kernel $K_{xc}$, which is of central relevance for many applications, such as time-dependent density functional theory (TD-DFT). This gives us a first unbiased look into the electronic density response of hydrogen in the warm-dense matter regime, thereby opening up a gamut of avenues for future research.

description: The evolution of the number density of galaxies in the universe, and thus also the total number of galaxies, is a fundamental question with implications for a host of astrophysical problems including galaxy evolution and cosmology. However there has never been a detailed study of this important measurement, nor a clear path to answer it. To address this we use observed galaxy stellar mass functions up to $z\sim8$ to determine how the number densities of galaxies changes as a function of time and mass limit. We show that the increase in the total number density of galaxies ($ϕ_{\rm T}$), more massive than M$_{*} = 10^{6}$ M_0, decreases as $ϕ_{\rm T} \sim t^{-1}$, where $t$ is the age of the universe. We further show that this evolution turns-over and rather increases with time at higher mass lower limits of M$_{*}>10^{7}$ M_0. By using the M$_{*}=10^{6}$ M_0 lower limit we further show that the total number of galaxies in the universe up to $z = 8$ is $2.0^{+0.7}_{-0.6} \times 10^{12}$ (two trillion), almost a factor of ten higher than would be seen in an all sky survey at Hubble Ultra-Deep Field depth. We discuss the implications for these results for galaxy evolution, as well as compare our results with the latest models of galaxy formation. These results also reveal that the cosmic background light in the optical and near-infrared likely arise from these unobserved faint galaxies. We also show how these results solve the question of why the sky at night is dark, otherwise known as Olbers' paradox.

The dispersion and propagation of topological Langmuir-cyclotron waves in cold magnetized plasmas

Year: 2022

description: Topological Langmuir-Cyclotron Wave (TLCW) is a recently identified topological surface excitation in magnetized plasmas. We show that TLCW originates from the topological phase transition at the Langmuir wave-cyclotron wave resonance. By isofrequency surface analysis and 2D and 3D time-dependent simulations, we demonstrate that the TLCW can propagate robustly along complex phase transition interfaces in a unidirectional manner and without scattering. Because of these desirable features, the TLCW could be explored as an effective mechanism to drive current and flow in magnetized plasmas. The analysis also establishes a close connection between the newly instituted topological phase classification of plasmas and the classical CMA diagram of plasma waves.

description: The Nagel-Schreckenberg model with overtaking strategy (NSOS) is proposed, and numerical simulations are performed for both closed and open boundary conditions. The fundamental diagram, space-time diagram, and spatial-temporal distribution of speed are investigated. In order to identify the synchronized flow state, both the correlation functions (autocorrelation and cross-correlation) and the one-minute average flow rate vs. density diagram are studied. All the results verify that synchronized flow does occur in our model.

Die Weitergabe von Traumata über Generationen hinweg: Auswirkungen auf fremdplatzierte Kinder und die Rolle der Sozialen Arbeit: Die seelische Gesundheit von ausserfamiliär untergebrachten Kindern
Creators: name: Galliker, Selina
Publisher: name: Zenodo
Year: 2023

description: Das Ziel dieser Bachelorarbeit ist eine vertiefte Auseinandersetzung mit der Rolle der Sozialen Arbeit bei fremdplatzierten Kinder n in der Kinder- und Jugendhilfe. Im Zentrum der Literaturarbeit steht die Überlegung, wie die Soziale Arbeit fremdplatzierte Kinder umfassend unterstützen kann, um der transgenerationalen Weitergabe von Traumata entgegenzuwirken. In der stationären Kinder- und Jugendhilfe stellt die transgenerationale Weitergabe ein zentrales Thema dar. Es werden verschiedene Theorien zu Bindung und Entwicklung des Kindes dargelegt, sowie die rechtliche Grundlage des Kinderschutzes erläutert. Dabei werden effektive Unterstützungsmassnahmen für fremdplatzierte Kinder und ihr Familiensystem entwickelt. In der Zusammenarbeit mit dem Familiensystem ist eine Sensibilisierung der Sozialarbeitenden zentral. Das Bewusstsein für die Situation der Familien ist dabei von grosser Bedeutung. Auch die Kenntnis, dass eine Kindesschutzmassnahme der Auslöser für ein traumatisches Erlebnis sein kann, ist wichtig. Die Autorin ist d er Auffassung, dass ein Wandel bezüglich der stationären Kinder- und Jugendhilfe hin zu Institutionen, in denen Kinder von klein an bis ins junge Erwachsenenalter ununterbrochen leben können, eine Verbesserung der Ausgangslage für fremdplatzierte Kinder zu r Folge hätte. Auch müssten sich die Institutionen noch mehr als Einrichtungen verstehen, in welche n die interdisziplinäre Zusammenarbeit gefördert und gestärkt würde. Die transgenerationale Weitergabe von Traumata könnte dadurch abgefedert werden und ein konstanter Wohnort würde ermöglicht werden. Die Autorin ist zudem der Auffassung, dass präventive Massnahmen zur Unterstützung der Familien, sich positiv auf das Familiensystem auswirken könnten.

description: We investigate the structure $X(4630)$ discovered by the LHCb collaboration in the process $B^{+}\rightarrow J/ψϕK^{+}$ as a resonance in the $ J/ψϕ$ mass distribution. We explore this resonance as a diquark-antidiquark state $X=[cs][\overline{c}\overline{s}]$ with spin-parities $J^{\mathrm{PC}}=1^{-+}$. Its mass and current coupling are calculated using the QCD two-point sum rule method by taking into account vacuum condensates up to dimension $10$. We also study decays of this tetraquark to mesons $J/ψϕ$, $η_{c}η^{(\prime )}$, and $χ_{c1}η^{(\prime )}$, and compute partial widths of these channels. To this end, we employ the light-cone sum rule approach and technical methods of soft-meson approximation to extract strong coupling at relevant tetraquark-meson-meson vertices. Our predictions for the mass $m=(4632\pm 60)~\mathrm{MeV}$ and width $Γ=(159\pm 31)~\mathrm{MeV}$ of $X$ are in a very nice agreement with recent measurements of the LHCb collaboration. These results allow us to interpret the resonance $X(4630)$ as the tetraquark $X$ with spin-parities $J^{\mathrm{PC}}=1^{-+}$.

description: The ability of young stellar clusters to expel or retain the gas left over after a first episode of star formation is a central issue in all models aiming to explain multiple stellar populations and the peculiar light element abundance patterns in globular clusters. Recent attempts to detect the gas left over from star formation in present day clusters with masses similar to those of globular clusters did not reveal a significant amount of gas in the majority of them, which strongly restricts the scenarios of multiple stellar population formation. Here the conditions required to retain the gas left over from star formation within the natal star forming cloud are revised. It is shown that the usually accepted concept regarding the thermalization of the star cluster kinetic energy due to nearby stellar winds and SNe ejecta collisions must be taken with care in the case of very compact and dense star forming clouds where three star formation regimes are possible if one considers different star formation efficiencies and mass concentrations. The three possible regimes are well separated in the half-mass radius and in the natal gas central density vs pre-stellar cloud mass parameter space. The two gas free clusters in the Antennae galaxies and the gas rich cluster with a similar mass and age in the galaxy NGC 5253 appear in different zones in these diagrams. The critical lines obtained for clusters with a solar and a primordial gas metallicity are compared.
