description: Despite the growing body of coaching literature that has illuminated the ‘relational’ picture of coaching, the spatial and temporal dimensions of coaching have often been overlooked. Inspired by Henri Lefebvre’s (1991, 2004) writings of ‘The Production of Space’ and ‘Rhythmanalysis’, the aim of this doctoral thesis project was to critically examine the production of everyday ‘space(s)’ in coaching. Following an ethnographic design, the precise research methods included participant observation, informal conversation, semi-structured interview, and the use of visual methods (i.e., researcher-driven photography and ‘auto-photography’). The findings used ‘rhythmanalysis’ as an analytic tool to de-construct mundane coaching practices by illuminating the dialectic of the temporalised space(s) and the localised (or what can be labelled as ‘living’) time. Of particular interest, then, was paid to the member’s bodily practice of embodiment and vision, which acted as essential constituents of re-producing and materialising the space-time. In turn, the analytic lens also stretched to how the everyday rhythms were dictated by the dominant group (coaches), while also illustrating in what ways those under the control (athletes) subtly displayed agency ‘over’ the space-time. The research findings represent the production of dominant material realities of coaching (i.e., spatiality and temporality) are ‘inseparable’ from the human mental (epistemological) practices, revealing the irreducible relation between space, time, and human bodily practices. From this perspective, it is hoped the thesis contributes to the theoretical breadth and critical analysis of the everyday ‘practical’ realities of coaching.
Improving the OCL Semantics Definition by Applying Dynamic Meta Modeling and Design Patterns

description: OCL is a standard specification language, which will probably be supported by most software modeling tools in the near future. Hence, it is important for OCL to have a solid formal foundation, for its syntax and its semantic definition. Currently, OCL is being formalized by metamodels expressed in MOF, complemented by well formedness rules written in the own OCL. This recursive definition not only brings about formal problems, but also puts obstacles in language understanding. On the other hand, the OCL semantics metamodel presents quality weaknesses due to the fact that certain object-oriented design rules (patterns) were not obeyed in their construction. The aim of the proposal presented in this article is to improve the definition for the OCL semantics metamodel by applying GoF patterns and the dynamic metamodeling technique. Such proposal avoids circularity in OCL definition and increases its extensibility, legibility and accuracy.

In search of the primordial communists : André Breton, surrealism and the indigenous societies of North America
Creators: name: Semerjian, Victor
Publisher: name: University of British Columbia
Year: 2009

description: During the 1920s and 1930s in Europe, Andre Breton was actively engaged in anti-colonial pursuits as a result of his commitment to socialist international revolutionary politics. That this was the case is evident in the numerous treatises and lectures in which Breton spoke out against imperialism and its oppression of non-Western peoples. During the same period, Breton also collected and displayed North American indigenous objects. When Breton was forced to flee to New York in the 1940s due to fascist persecution, he continued to engage in these practices. Rather than viewing these activities as separate and unrelated, this thesis intends to argue that one of the reasons North American indigenous objects were collected and evoked by Breton was because the societies that produced them occupied an exalted place within European socialist ideology. Certainly, there have been art historical studies devoted to the subject of Breton's aligning surrealism with socialist international revolutionary causes. Moreover, in the existing writings on surrealism and indigenous peoples, the attention paid to North American indigenous societies by Breton has been noted. However, in this latter discourse, Breton's interest in North American aboriginal groups, whether in Europe or in the United States and Canada, has been confined to issues of mythology, psychoanalysis, aesthetics and connoisseurship and, hence, the left wing political importance of these societies has been overlooked. Drawing upon the body of post-colonial critiques engaging the cooption and appropriation of other cultures by the West, this thesis will investigate the European socialist significance of North American indigenous societies and bring it to a discussion of Breton's collecting and display practices. Of particular importance in this matter are the writings of Frederick Engels in which ethnographic data on North American aboriginal peoples was used to offer "proof" that the first human communities existed in a state of primordial communism. What will be argued is that varied dimensions of these imaginary societies were evoked by Breton in left wing strategies during the 1930s and 1940s as part of an oppositional stand against bourgeois ideology, imperialism, fascism and war. To be sure, the collecting and exhibiting of indigenous objects brimming with socialist significance was not solely defined by political activism; these pursuits were as well bound up with issues of avant-gardism and so-alled "primitivism." In order to pursue this matter, this thesis will also draw upon analyses of modernism and the avant-garde in order to provide a clearer view of how and why certain North American aboriginal peoples were drawn into Breton's artistic and political international revolutionary avant-garde strategies at various moments and in differing geographic locales.

description: The Object Constraint Language (OCL) provides a set of powerful facilities for navigating and querying models in the MOF metamodelling architecture. Currently, OCL queries can be expressed only in the context of MOF metamodels and UML models. This adds an additional burden to the development and use of Domain Specific Languages, which can also benefit from an instance-level querying mechanism. In an effort to address this issue, we report on ongoing work on defining a rigorous approach for aligning the OCL querying and navigation facilities with arbitrary Domain Specific Languages to support instance-level queries. We present a case-study that demonstrates the usefulness and practicality of this approach.

description: In a model assessment framework different quality aspects can be examined. In our approach we consider consistency and perceived semantic quality. The former can be supported by constraints and the later by queries. Consistency can be checked automatically, while for the semantic quality the human judgement is necessary. For constraint and query definitions the utilisation of a query language was necessary. We present a case study that evaluates the expressiveness of the Object Constraint Language (OCL) in the context of our approach. We focus on typical queries required by our methodology and we showed how they can be formulated in OCL. To take full advantage of the languageâs expressiveness, we utilise new features of OCL 2.0. Based on our examination we decided to use OCL in our analysis tool and we designed an architecture based on Eclipse Modeling Framework Technology.

description: We report the observation of $\B_s^0-\bar{B}_s^0$ oscillations performed by the CDF II detector using a data sample of 1 $fb^{-1}$ of $p\bar{p}$ collisions at $\sqrt{s}=1.96 \TeV$. We measure the probability as a function of proper decay time that the $B_s$ decays with the same, or opposite, flavor as the flavor at production, and we find a signal for $\B_s^0-\bar{B}_s^0$ oscillations. The probability that random fluctuations could produce a comparable signal is $8 \times 10^{-8}$, which exceeds $5σ$ significance. We measure $Δm_s = 17.77 \pm{0.10} ({\rm stat}) \pm{0.07} ({\rm syst}) ps^{-1}$. A very important update has been presented by the CDF collaboration after I gave my talk, the latest available results on $B_s$ mixing are included here.

description: In oxide epitaxy, the growth temperature and background oxygen partial pressure are considered as the most critical factors that control the phase stability of an oxide thin film. Here, we report an unusual case wherein diffusion of oxygen vacancies from the substrate overpowers the growth temperature and oxygen partial pressure to deterministically influence the phase stability of $Bi_{2}WO_{6}$ thin film grown by the pulsed laser deposition technique. We show that when grown on an oxygen-deficient $SrTiO_{3}$ substrate, the $Bi_{2}WO_{6}$ film exhibits a mixture of (001) and (100)/(010)-oriented domains alongside (001)-oriented impurity $WO_{3}$ phases. The (100)/(010)-oriented $Bi_{2}WO_{6}$ phases form a self-organized 3D nanopillar-structure, yielding a very rough film surface morphology. Oxygen annealing of the substrate or using a few monolayer-thick $SrRuO_{3}$ as the blocking layer for oxygen vacancy diffusion enables growing high-quality single-crystalline $Bi_{2}WO_{6}$ (001) thin film exhibiting an atomically smooth film surface with step-terrace structure. We propose that the large oxide-ion conductivity of $Bi_{2}WO_{6}$ facilitates diffusion of oxygen vacancies from the substrate during the film growth, accelerating the evaporation of volatile Bismuth (Bi), which hinders the epitaxial growth. Our work provides a general guideline for high-quality thin film growth of Aurivillius compounds and other oxide-ion conductors containing volatile elements.

description: The experimental data on F2 structure functions of the proton and deuteron were used to construct their moments. In particular, recent measurements performed with CLAS detector at Jefferson Lab allowed to extend our knowledge of structure functions in the large-x region. The phenomenological analysis of these experimental moments in terms of the Operator Product Expansion permitted to separate the leading and higher twist contributions. Applying nuclear corrections to extracted deuteron moments we obtained the contribution of the neutron. Combining leading twist moments of the neutron and proton we found d/u ratio at x->1 approaching 0, although 1/5 value could not be excluded. The twist expansion analysis suggests that the contamination of higher twists influences the extraction of the d/u ratio at x->1 even at Q2-scale as large as 12 (GeV/c)^2.

An experimental study of the effects of the use of an expert support system and its explanation facilities on group decision making
Creators: name: Nah, Fui Hoon Fiona
Publisher: name: University of British Columbia
Year: 2009

description: As information technology is increasingly used in organizations to support group work, it is important to understand how group decision making processes are moderated by the provision of computer-based decision support facilities. This research examines the effects of utilizing an Expert Support System (ESS) and its explanation facilities on group decision making. Four persuasion theories form the main theoretical foundations of this research: the elaboration likelihood model, the social judgment theory, the information processing paradigm, and the cognitive response theory. An experimental study was carried out to examine the suitability of using an ESS to support groups in making financial analysis decisions. Three levels of decision support — no ESS support, ESS analyses without explanations support, ESS analyses plus explanations support — were examined. Two groups of subjects — experts and novices — participated in the study. The findings are consistent with the widely-held belief that for an ESS to be useful, both ESS analyses and explanations support are necessary; they both contribute to knowledge transfer from the ESS to the novice decision makers. ESS explanations also increase users' trust in the system. ESS support, however, decreases users' satisfaction with the group process. The expert-novice comparison shows that novices find the ESS to be more useful than experts do. Experts are not only more capable of processing the available information, but they also tend to be more critical and ego-involved in their area of expertise. These characteristics decrease experts' likelihood of being persuaded by the ESS and account for the lower consensus among the experts compared to novices. This research represents one of the first studies to investigate the use of ESS technology in group settings. It integrates quantitative, statistical, and positivist methods with qualitative, case, and interpretive methods to provide a rich understanding and description of the group processes and outcomes. In terms of theoretical contributions, it integrates persuasion theories into research on the use of ESS technology for group decision making. For practitioners and managers, the findings indicate that a high quality ESS, with both its analyses and explanations components, could be used to improve the quality of group judgments.

description: Efficient constraint handling is essential in UML, in metamodeling as well as in model transformation. OCL is a popular, textual formal language that is used in most of the modeling frameworks to express constraints. Our research focuses on the optimization of OCL handling. Previous work have presented algorithms that can accelerate the constraint validation by rewriting and decomposing the constraints and caching the model queries. Although these algorithms can be used in general, there are special cases, where additional restrictions apply. The aim of this paper is to present these refined restrictions and the extended optimization algorithms.

description: Extraction of hadronic observables at finite-momenta from Lattice QCD (LQCD) is constrained by the well-known signal-to-noise problems afflicting all such LQCD calculations. Traditional quark smearing algorithms are commonly used tools to improve the statistical quality of hadronic $n$-point functions, provided operator momenta are small. The momentum smearing algorithm of Bali et al. extends the range of momenta that are cleanly accessible, and has facilitated countless novel lattice calculations. Momentum smearing has, however, not been explicitly demonstrated within the framework of distillation. In this work we extend the momentum-smearing idea, by exploring a few modifications to the distillation framework. Together with enhanced time slice sampling and expanded operator bases engendered by distillation, we find ground-state nucleon energies can be extracted reliably for $\left|\vec{p}\right|\lesssim3\text{ GeV}$ and matrix elements featuring a large momentum dependence can be resolved.

Design of a Railway Domain Profile and its OCL-based Validation
Creators: name: Berkenkötter, Kirsten
Publisher: name: European Association of Software Science and Technology
Year: 2007

description: Domain-specific languages become more and more important these days as they facilitate the close collaboration of domain experts and software developers. One effect of this general tendency is the increasing number of UML profiles. UML itself as the most popular modeling language is capable of modeling all kinds of systems but it is often inefficient due to its  wide-spectrum approach. Profiles tailor the UML to a specific domain and can hence be seen as domain-specific dialects of
UML. At the moment, profiles mainly introduce new terminology, often in combination with OCL constraints which describe the new constructs more precisely. As most tools do not support validation of OCL expressions let alone supplementing
profiles with OCL constraints, it is difficult to check if models based on a profile comply to this profile. A related problem is checking whether constraints in the profile contradict constraints in the UML specification. In this paper, it is shown how to complete these tasks with the tool USE. As an example, a profile from the railway control systems domain is taken which describes the use of its modeling elements quite strictly. Models based on this profile serve as a foundation for automated code
generation. Therefore, they require a rigorous and unambiguous meaning. OCL is heavily used to reach this goal.

description: Vector theories with spontaneous Lorentz violation, known as bumblebee models, are examined in flat spacetime using a Hamiltonian constraint analysis. In some of these models, Nambu-Goldstone modes appear with properties similar to photons in electromagnetism. However, depending on the form of the theory, additional modes and constraints can appear that have no counterparts in electromagnetism. An examination of these constraints and additional degrees of freedom, including their nonlinear effects, is made for a variety of models with different kinetic and potential terms, and the results are compared with electromagnetism. The Hamiltonian constraint analysis also permits an investigation of the stability of these models. For certain bumblebee theories with a timelike vector, suitable restrictions of the initial-value solutions are identified that yield ghost-free models with a positive Hamiltonian. In each case, the restricted phase space is found to match that of electromagnetism in a nonlinear gauge.

description: Mit jährlich durchschnittlich 5'700 Neuerkrankungen stellt Brustkrebs die häufigste Tumorerkrankung bei Frauen dar. Die Diagnose bedeutet meist ein lebensveränderndes Ereignis. Die ambulante Sozialarbeit in der Onkologie begleitet die betroffenen Frauen in allen Phasen der Erkrankung und stellt so ein wesentliches Element in der psychosozialen Versorgung dar. Die vorliegende Masterthesis befasst sich mit der subjektiven Wahrnehmung der betroffenen Frauen in Bezug auf die Dienstleistungen der ambulanten Sozialarbeit in der Onkologie. Genauer wird eruiert, welche krankheitsbedingten Herausforderungen bestehen und welchen Beitrag die ambulante Sozialarbeit im Hinblick auf spezifische Folgeerscheinungen aus subjektiver Sicht der Betroffenen leistet. Es wurden dabei problemzentrierte Interviews mit sechs betroffenen Frauen geführt, welche die Sozialberatung der regionalen Krebsligen der Schweiz in Anspruch genommen haben. Die Ergebnisse dieser Umfrage zeigen, dass vor dem theoretischen Hintergrund des biopsychosozialen Modells multifaktorielle krankheitsbedingte Herausforderungen bestehen. Des Weiteren wurden individuelle Copingstrategien im Umgang mit den Folgeerscheinungen ersichtlich. Die Betroffenen bescheinigten der ambulanten Sozialarbeit diverse Funktionen und Beratungskompetenzen, welche im Hinblick auf die krankheitsbedingten Herausforderungen eine Erleichterung bedeuteten.

description: Rotation is a significant characteristic of the Sun and other stars, and it plays an important role in understanding their dynamo actions and magnetic activities. In this study, the rotation of the solar chromospheric activity is investigated from a global point of view with an over 40 yr Mg II index. We determined the time-varying rotational period lengths (RPLs) with the synchrosqueezed wavelet transform which provides high temporal and frequency resolution; furthermore, we compared the RPLs with the photospheric and coronal RPLs obtained from the sunspot numbers and the 10.7 cm radio flux data. The significance of the RPLs is taken into consideration. We found that the RPLs of the chromosphere exhibit a downward trend, as do those that of the photosphere and corona; in addition, their RPLs at the recent four solar maxima also show a declining trend. It suggests that the rotation of the solar atmosphere has been accelerating during the recent four solar cycles, which is inferred to be caused by the declining strength of solar activity. The variations of the solar atmospheric RPLs show periodicities of multiple harmonics of the solar cycle period, and it is modulated by the solar activity cycle.

description: We propose a non-linear extension of the Fierz-Pauli mass for the graviton through a functional of the vielbein and an external Minkowski background. The functional generalizes the notion of the measure, since it reduces to a cosmological constant if the external background is formally sent to zero. Such a term and the explicit external background, emerge dynamically from a bi--gravity theory, having both a massless and a massive graviton in its spectrum, in a specific limit in which the massless mode decouples, while the massive one couples universally to matter. We investigate the massive theory using the Stueckelberg method and providing a 't Hooft-Feynman gauge fixing in which the tensor, vector and scalar Stueckelberg fields decouple. We show that this model has the softest possible ultraviolet behavior which can be expected from any generic (Lorentz invariant) theory of massive gravity, namely that it becomes strong only at the scale Lambda_3 = (m_g^2 M_P)^{1/3}.

The most advantage of our proposed method is that the a priori estimate and the existence result are independent of small data and the large viscosity restriction. Therefore the global uniqueness of the weak solution is naturally obtained.

Confessions of a Meta-Modeller

Publisher: name: European Association of Software Science and Technology

description: Meta-modelling tools are a very useful technology in software engineering tool development, increasing a tool developer s productivity and permitting more focus on the new tool s metaphorical abstractions and notations rather than the technical features of implementation. Constructing meta-modelling tools is, however, a challenging occupation with many interacting technical needs. In the process of managing these needs, the question of diagram layout support has typically been seen as being of low priority. This results in an inability for meta-tool users to specify their notational metaphors efficiently or appropriately, and for the generated tools to be unable to effectively manage diagrams of significant scale and complexity. In this presentation I will examine the deficiencies of current meta-tool layout approaches and the problems these cause for notational designers, tool implementers and end users. I will then discuss some directions we have been taking to enhance diagram layout capability in our own meta-tool work before examining broader issues regarding software tool layout support. This will raise a set of challenges for the community to permit the provision of more understandable and scalable interactive software engineering diagrams while retaining the productivity benefits of a meta-tool approach for their specification.

description: We give detailed results of $\mathcal{O}(α)$ QED corrections (both real emission and virtual corrections) to $B\to K\ell^+\ell^-$ modes. Requiring the real emission to be gauge invariant, the structure of the contact term(s) is fixed. The calculation is done with a fictitious photon mass as the IR regulator and results are shown to be independent of it, establishing cancellation of the soft divergences. Results are presented for a choice of photon energy, $k_{max}$, and photon angle $θ_{cut}$. The QED effects are negative, thereby reducing the rate compared to that without QED effects. Electron channels are shown to receive large corrections ($\mathcal{O}(20\%)$). Impact on lepton flavour universality ratio, $R^{μe}_K$ are also discussed.

Sozialhilfebezug als Risiko: Soziale Arbeit an der Schnittstelle zwischen Existenzsicherung, Integration und Aufenthaltsrecht

Publisher: name: Zenodo
Year: 2021

description: Migrations-, integrations- und sozialpolitische Bestimmungen haben sich seit der Einführung des Bundesgesetzes über die Ausländerinnen und Ausländer (AuG) im Jahr 2008 zusehends verschränkt. Die im revidierten Ausländer- und Integrationsgesetz (AIG) definierten Integrationskriterien legen die finanzielle Autonomie respektive die Sozialhilfeunabhängigkeit als eine zentrale Voraussetzung für die Erteilung und Verlängerung einer Aufenthalts- oder Niederlassungsbewilligung für Ausländer*innen aus Drittstaaten fest. Die vorliegende Masterarbeit fragt nach den Auswirkungen, die das gesetzlich verankerte Integrationsverständnis auf die sozialarbeiterische Praxis hat und wie sich das Integrationsverständnis des AIG mit dem Integrationsauftrag der Sozialhilfe vereinbaren lässt. Empirisch basiert die Arbeit auf fünf Expert*inneninterviews mit Vertreter*innen von Schlüsselinstitutionen der betroffenen Handlungsfelder. Die Auswertung der Interviews mittels qualitativer Inhaltsanalyse hat Widersprüche in der Anwendung von ausländerrechtlichen Massnahmen bei Sozialhilfebezug erkennbar gemacht. Diese zeigen sich insbesondere in den unterschiedlichen Integrationsanforderungen und -bemühungen zwischen Sozialdiensten und Migrationsbehörden. Die rechtliche Koppelung von Existenzsicherung und Aufenthaltsregelung sowie die strenge Anwendung ausländerrechtlicher Sanktionen führt zu einer Verschiebung von Problemlagen, die mit dem Integrationsauftrag der Sozialhilfe teilweise kollidiert. Im Extremfall verzichten armutsgefährdete Ausländer*innen auf Sozialhilfeleistungen, was den Ausschluss aus dem System sozialer Sicherung bedingt und Integration im Sinne einer gleichberechtigten gesellschaftlichen Teilhabe behindert. Für Sozialarbeitende, die auf öffentlichen Sozialdiensten für die Ausrichtung der Sozialhilfe und die soziale sowie berufliche Integration ihrer Klient* innen verantwortlich sind, führen die gesetzlichen Verschärfungen im AIG zu Verunsicherungen, während ihnen im Prozess der Aufenthaltsregelung gleichzeitig eine wichtige Rolle zukommt.

description: Euler diagrams have numerous application areas, with a large variety of languages based on them. In relation to software engineering, such areas encompass modelling and specification including from a formal perspective. In all of these application areas, it is desirable to provide tools to layout Euler diagrams, ideally in a nice way. Various notions of `niceness' can be correlated with certain properties that an Euler diagram may or may not possess. Indeed, the relevant layout algorithms developed to date produce Euler diagrams that have certain sets of properties, sometimes called well-formedness conditions. However, there is not a commonly agreed definition of an Euler diagram and the properties imposed on them are rarely stated precisely. In this paper, we provide a very general definition of an Euler diagram, which can be constrained in varying ways in order to match the variety of definitions that exist in the literature. Indeed, the constraints imposed correspond to properties that the diagrams may possess. A contribution of this paper is to provide formal definitions of these properties and we discuss when these properties may be desirable. Our definition of an Euler diagram and the formalization of these properties provides a general language for the Euler diagram community to utilize. A consequence of using a common language will be better integration of, and more accessible, research results.

description: New observations of high-redshift objects are crucial for the improvement of the standard $Λ$CDM cosmological model and our understanding of the Universe. One of the main directions of modern observational cosmology is the analysis of the large-scale structure of Universe, in particular, in deep fields. We study the large-scale structure of the Universe along the line of sight using the latest version of the COSMOS2015 catalogue, which contains 518,404 high quality photometric redshifts of galaxies selected in the optical range of the COSMOS field ($2\times 2$ deg$^2$), with depth up to the redshift $z \sim 6$. We analyze large-scale fluctuations in the number of galaxies along the line of sight and provide an estimate of the average linear sizes of the self-correlating fluctuations (structures) in independent redshift bins of $ Δz = 0.1 $ along with the estimate of the standard deviation from homogeneity (the observed cosmic variance). We suggest a new method of the line-of-sight analysis based on previous works and formulate further prospects of method development. For the case of the theoretical form of approximation of homogeneity in the $Λ$CDM framework, the average standard deviation of detected structures from homogeneity is $ σ_\text{mean}^{Λ\text{CDM}} = 0.09 \pm 0.02 $, and the average characteristic size of structures is $ R_\text{mean}^{Λ\text{CDM}} = 790 \pm 150 $ Mpc. For the case of the empirical approximation of homogeneity, the average standard deviation of detected structures from homogeneity is $ σ_\text{mean}^\text{empiric} = 0.08 \pm 0.01 $, and the average characteristic size of structures is $ R_\text{mean}^\text{empiric} = 640 \pm 140 $ Mpc.

"Ich will zu Hause essen …" - Herausgeforderte Kinder in der Tagesschule: Eine qualitative Untersuchung zum Wohlbefinden

Publisher: name: Zenodo

description: In der Schweiz wie auch in Deutschland findet seit 17 Jahren ein starker Ausbau von öffentlichen Tagesschulen mit unterschiedlichen Modellen der ganztägigen Bildung und Betreuung statt. Infolge rechtlicher Grundlagen und der Umsetzung eines erweiterten Inklusionsbegriff wird das Ziel verfolgt, Kinder mit besonderem Förderbedarf zunehmend in Regelklassen zu beschulen. Zudem steigen die Zahlen der ausserfamiliär betreuten Kinder stetig an. Studien weisen darauf hin, dass Kinder mit besonderem Förderbedarf im Bereich Verhalten mehr Stress in der Schule erleben als andere Kinder. Es kann daher davon ausgegangen werden, dass dies auch für Tagesschulen zutrifft. Leitend für dieses qualitative Forschungsprojekt ist deshalb die Frage, wie herausgeforderte Kinder die Betreuungszeiten in Tagesschulen erleben. Die vorliegende Arbeit geht den für diese Kinder sich ergebenden Chancen und Herausforderungen in Tagesschulen nach. Dazu wurden in zwei verschiedenen öffentlichen, freiwilligen Tagesschulen insgesamt sechs Beobachtungen während der Mittagsbetreuung durchgeführt. Die ausformulierten Feldnotizen wurden anhand der Verfahren der Grounded Theory nach Strauss und Corbin ausgewertet und theoretisch diskutiert. Es konnte herausgearbeitet werden, dass positives Erleben und Wohlbefinden durch das Vorhandensein vieler förderlicher Bedingungen zwar gegeben sein kann, aber nicht zwingend dem (aktuellen) Befinden einzelner Kinder entsprechen muss. Daneben stellte sich das gemeinsame Spiel der Betreuungspersonen mit den Kindern als eine weitere zentrale Strategie zur Beziehungsarbeit heraus. Das Vorkommen von prosozialen Verhaltensweisen bei den Peers zeigte sich für eine gelingende Integration herausgeforderter Kinder ebenfalls als sehr unterstützend. Entsprechend wurden Hinweise und Schlussfolgerungen für die Praxis der sozialpädagogischen Betreuung in Tagesschulen abgeleitet und formuliert. In weiteren Forschungen sind die Befunde zu erhärten sowie die spezifischen Qualitätsmerkmale und förderlichen Rahmenbedingungen der Tagesschulangebote auf struktureller, personaler, pädagogischer, räumlicher, organisatorischer und systemübergreifender Ebene in Bezug auf die Förderung der Persönlichkeitsentwicklung und des Wohlbefindens herausgeforderter Kinder zu identifizieren, um genauere Aussagen zum Erreichen des Ziels machen zu können.

description: Resources are rarely distributed uniformly within a population. Heterogeneity in the concentration of a drug, the quality of breeding sites, or wealth can all affect evolutionary dynamics. In this study, we represent a collection of properties affecting the fitness at a given location using a color. A green node is rich in resources while a red node is poorer. More colors can represent a broader spectrum of resource qualities. For a population evolving according to the birth-death Moran model, the first question we address is which structures, identified by graph connectivity and graph coloring, are evolutionarily equivalent. We prove that all properly two-colored, undirected, regular graphs are evolutionarily equivalent (where "properly colored" means that no two neighbors have the same color). We then compare the effects of background heterogeneity on properly two-colored graphs to those with alternative schemes in which the colors are permuted. Finally, we discuss dynamic coloring as a model for spatiotemporal resource fluctuations, and we illustrate that random dynamic colorings often diminish the effects of background heterogeneity relative to a proper two-coloring.

Eignung privater Beistandspersonen im Erwachsenenschutz aus Sicht der Sozialen Arbeit: Erarbeitung eines Kompetenzprofils auf der Basis von lebensweltorientierter und sozialraumorientierter Sozialer Arbeit

description: Im Jahr 2019 wurden 37% der Erwachsenenschutzmassnahmen in der Schweiz von privaten Personen geführt. Private Beistandspersonen leisten somit eine wichtige Arbeit im Bereich des Erwachsenenschutzes. Berufsbeistandspersonen können eine Ausbildung zur Mandatsführung absolvieren, daher muss davon ausgegangen werden, dass auch private Beistandspersonen gewisse Fähigkeiten mitbringen müssen um erfolgreich, im Sinne der Rechtsordnung, der KESB sowie der betroffenen Person, ein Mandat führen zu können. Das Ziel dieser Master-Thesis ist, aus der Sicht der Sozialen Arbeit, Kompetenzen zu formulieren, welche private Beistandspersonen für eine erfolgreiche Mandatsführung im Erwachsenenschutz mitbringen sollten. Bisher existieren keine Forschungen und kaum Vorgaben mit Sicht aus der Sozialen Arbeit zu der Fragestellung nach den Kompetenzen von privaten Beistandspersonen. Diese Forschungslücke bearbeitet diese Master-Thesis, um eine Basis für weitere Forschungen, aber auch für die Entwicklungen der Fachstellen für private Beistandspersonen zu bieten. Die vorliegende Master-Thesis beruht auf einer theoretischen Bearbeitung des Erwachsenenschutzrechts sowie der Theorien der Lebensweltorientierten und Sozialraumorientierten Sozialen Arbeit. Die Ergebnisse der theoretischen Bearbeitung wurden genutzt, um erste Antworten auf die Frage zu erhalten, was die Eignung privater Beistandspersonen aus Sicht der Sozialen Arbeit definiert. Davon ausgehend wurde eine qualitativ-empirische Analyse durchgeführt. Die Experteninterviews fanden mit Sozialarbeitenden statt, welche in der Deutschschweiz auf Fachstellen für private Beistandspersonen tätig und für die Rekrutierung sowie Begleitung dieser zuständig sind. Die Interviews wurden anhand der qualitativen Inhaltsanalyse ausgewertet. Es konnten Kompetenzen aus der Analyse abgeleitet werden, welche für private Beistandspersonen wichtig sind, um ein Mandat erfolgreich führen zu können. Dazu gehören insbesondere Sozial- und Selbstkompetenzen. Ein zentrales Ergebnis der Master-Thesis ist, dass die Kompetenzen, welche eine private Beistandsperson benötigt, einerseits stark von den Aufgaben, welche von der KESB definiert wurden, aber auch von der betroffenen Person und deren Umfeld abhängig sind. Daher empfiehlt es sich, dass die Fachstellen individuell die privaten Beistandspersonen begleiten, vorhandene Kompetenzen stärken und noch fehlende Kompetenzen schulen.
