description: In der vorliegenden Bachelorarbeit befassen sich die beiden Autorinnen Solveig Bühler und Nora Zumoberhaus mit der subjektiven Wahrnehmung von Migrant*innen auf ihre Integration in den Schweizer Arbeitsmarkt. Sie interessieren sich für die individuell wahrgenommenen förderlichen und hinderlichen Aspekte, welche sie anhand narrativen Interviews erfassten. Die Autorinnen gehen in der Arbeit drei Fragestellungen nach: zum bestehenden Forschungs- und Wissenstand, zu den subjektiven Erfahrungen der Interviewgruppe sowie zur Rolle und Relevanz der Sozialen Arbeit. Die Forschungsergebnisse wurden anschliessend mit dem Wissensstand der Literatur diskutiert und daraus Handlungsempfehlungen für die Soziale Arbeit aufgestellt. Es wurde ersichtlich, dass die aktivierende Arbeitsmarktpolitik das Ziel verfolgt, die Eingliederung in die Arbeitswelt möglichst schnell zu gestalten und dabei die Begeisterung und Sinnhaftigkeit für eine Arbeitsstelle unter Umständen unbeachtet bleibt. Eine weitere Erkenntnis stellt die grosse Motivation der befragten Personen dar, die als Ressource genutzt werden kann, sofern diese als solche anerkannt wird. Netzwerke wurden nicht nur während der Interviews als sehr bedeutender, förderlicher Faktor genannt; Auch die Autorinnen erkannten in solchen sozialen Gefügen und Beziehungen einen hohen Stellenwert für migrierte Personen, da die befragten Personen im Prozess der Integration in den Schweizer Arbeitsmarkt nie zur Zielgruppe von Programmen der Arbeitsintegration gehörten, sondern ihren Zugang oftmals selbständig durch Netzwerke geschaffen haben.

description: We present a semi-analytical model of the resonance phenomena occurring in a hybrid system made of a 1D array of periodic subwavelength slits deposited on an insulator/graphene layer. We show that the spectral response of this hybrid system can be fully explained by a simple semi-analytical model based on a weak and strong couplings between two elementary sub-systems. The first elementary sub-system consists of a 1D array of periodic subwavelength slits viewed as a homogeneous medium. In this medium lives a metal-insulator-metal lattice mode interacting with surface and cavity plasmon modes. A weak coupling with surface plasmon modes on both faces of the perforated metal film leads to a broadband spectrum while a strong coupling between this first sub-system and a second one made of a graphene-insulator-metal gap leads to a narrow band spectrum. We provide a semi-analytical model based on these two interactions allowing to efficiently access the full spectrum of the hybrid system.

description: Objective: The objective of this study was to assess the prevalence and sociodemographic characteristics of cesarean section in Ethiopia. Methods: We used data collected for Ethiopia Demographic and Health Surveys (DHS) conducted in 2000, 2005, 2011, and 2016. A two-stage, stratified, clustered random sampling design was used to gather information from women who gave birth within the 5-year period before each of the surveys. We analyzed the data to identify sociodemographic characteristics associated with cesarean section using log-Poisson regression models. Results: The national cesarean section rate increased from 0.7% in 2000 to 1.9% in 2016, with increases across seven of the eleven administrative regions of Ethiopia. Addis Ababa had the highest cesarean section rate (21.4%) in 2016 and the greatest increase since 2000. In the adjusted analysis, women who gave birth in private health facility had a 78.0% higher risk of cesarean section (adjusted prevalence ratio (aPR) (95% CI) 1.78 (1.22, 2.58)) compared with women who gave birth in public health facility. Having four or more births was associated with a lower risk of cesarean section compared with first births (aPR (95% CI) 0.36 (0.16, 0.79)). Conclusions: The Ethiopian national cesarean section rate is about 2%, but the rate varies widely among administrative regions, suggesting unequal access. Cesarean sections were highest among urban mothers, first births, births to women with higher education, and births to women from the richest quintile of household wealth.

description: In der vorliegenden Arbeit «Auswirkungen des bedingungslosen Grundeinkommens und der wirtschaftlichen Sozialhilfe auf die soziale und berufliche Integration» befasst sich die Autorin Anita Bühlmann mit der sozialen und beruflichen Integration sowie den beiden Systemen der sozialen Sicherheit: bedingungsloses Grundeinkommen und wirtschaftliche Sozialhilfe. Dabei geht sie den Fragen nach, welche Auswirkungen ein bedingungsloses Grundeinkommen und die wirtschaftliche Sozialhilfe auf die Integration haben und welche Schlussfolgerungen sich daraus für die Soziale Arbeit ableiten lassen. Dafür hat die Autorin fünf Projekte über das bedingungslose Grundeinkommen im Ausland sowie vier Studien über Integrationsmassnahmen in der wirtschaftlichen Sozialhilfe untersucht. Die Ergebnisse werden anhand von Theorien eingeordnet und aus Sicht der Sozialen Arbeit bewertet. Diese Einordnung und Bewertung zeigen, dass die Integration von persönlichen Bedürfnissen wie auch von vorhandenen Kapitalsorten abhängig ist. Bezahlte und unbezahlte Tätigkeiten wie auch die Teilnahme an Integrationsprogrammen fördern die Integration und wirken der sozialen Isolation entgegen. Dies bedeutet, dass die individuelle Situation der betroffenen Person zu berücksichtigen ist und bedürfnisgerechte Leistungen zu finanzieren sind. Die nach der Auseinandersetzung resultierenden Schlussfolgerungen sollen in künftige Überlegungen der Sozialen Arbeit einfliessen.

description: Topological excitations keep fascinating physicists since many decades. While individual vortices and solitons emerge and have been observed in many areas of physics, their most intriguing higher dimensional topological relatives, skyrmions (smooth, topologically stable textures) and magnetic monopoles -- emerging almost necessarily in any grand unified theory and responsible for charge quantization -- remained mostly elusive. Here we propose that loading a three-component nematic superfluid such as $^{23}$Na into a deep optical lattice and thereby creating an insulating core, one can create topologically stable skyrmion textures and investigate their properties in detail. We show furthermore that the spectrum of the excitations of the superfluid and their quantum numbers change dramatically in the presence of the skyrmion, and they reflect the presence of a trapped monopole, as imposed by the skyrmion's topology.

description: The emerging field of magnonics employs spin waves and their quanta, magnons, to implement wave-based computing on the micro- and nanoscale. Multi-frequency magnon networks would allow for parallel data processing within single logic elements whereas this is not the case with conventional transistor-based electronic logic. However, a lack of experimentally proven solutions to efficiently combine and separate magnons of different frequencies has impeded the intensive use of this concept. In this Letter, the experimental realization of a spin-wave demultiplexer enabling frequency-dependent separation of magnonic signals in the GHz range is demonstrated. The device is based on two-dimensional magnon transport in the form of spin-wave beams in unpatterned magnetic films. The intrinsic frequency-dependence of the beam direction is exploited to realize a passive functioning obviating an external control and additional power consumption. This approach paves the way to magnonic multiplexing circuits enabling simultaneous information transport and processing.

description: AD Leo (GJ 388) is an active dM3 flare star extensively observed both in the quiescent and flaring states. Since this active star is near the fully-convective boundary, to study in detail its long-term chromospheric activity could be an appreciable contribution for the dynamo theory. Here, we analyze with the Lomb-Scargle periodogram the Ca II K line-core fluxes derived from CASLEO spectra obtained between 2001 and 2013 and the V magnitude from the ASAS database between 2004 and 2010. From both totally independent time-series, we obtain a possible activity cycle of period $\sim7$ years and a less-significant shorter one of $\sim2$ years. A tentative interpretation is that a dynamo operating near the surface could be generating the longer cycle, while a second dynamo operating in the deep convection zone could be responsible for the shorter one. Based on the long duration of our observing program at CASLEO and the fact that we observe simultaneously different spectral features, we also analyze the relation between simultaneous measurements of the Na I index ($R^{\prime}_D$), H$α$ and Ca II K fluxes at different activity levels of AD Leo, including flares.

description: We study the extent to which divisors of a typical integer $n$ are concentrated. In particular, defining the Erdős-Hooley $Δ$-function by $Δ(n) := \max_t \# \{d | n, \log d \in [t,t+1]\}$, we show that $Δ(n) \geq (\log \log n)^{0.35332277\dots}$ for almost all $n$, a bound we believe to be sharp. This disproves a conjecture of Maier and Tenenbaum. We also prove analogs for the concentration of divisors of a random permutation and of a random polynomial over a finite field. Most of the paper is devoted to a study of the following much more combinatorial problem of independent interest. Pick a random set $A \subset \mathbb{N}$ by selecting $i$ to lie in $A$ with probability $1/i$. What is the supremum of all exponents $β_k$ such that, almost surely as $D \rightarrow \infty$, some integer is the sum of elements of $A \cap [D^{β_k}, D]$ in $k$ different ways? We characterise $β_k$ as the solution to a certain optimisation problem over measures on the discrete cube $\{0,1\}^k$, and obtain lower bounds for $β_k$ which we believe to be asymptotically sharp.

description: We introduce a new probabilistic model of the primes consisting of integers that survive the sieving process when a random residue class is selected for every prime modulus below a specific bound. From a rigorous analysis of this model, we obtain heuristic upper and lower bounds for the size of the largest prime gap in the interval $[1,x]$. Our results are stated in terms of the extremal bounds in the interval sieve problem. The same methods also allow us to rigorously relate the validity of the Hardy-Littlewood conjectures for an arbitrary set (such as the actual primes) to lower bounds for the largest gaps within that set.

description: Twenty-three patients with a mean age of 52.7 years underwent pulley reconstruction using the Okutsu double- or triple-loop technique after iatrogenic or traumatic rupture of at least two adjacent flexor tendon pulleys in the finger and distal palm; mean age of injury was 4.77 years. The mean follow-up was 4.66 years after reconstruction of mostly A2 pulleys in a single surgeon setting. Outcome measures included ROM, NRS pain, satisfaction, Disabilities of Arm, Shoulder and Hand Questionnaire (DASH) and Krimmer score, Buck–Gramcko score, Jamar grip strength, pinch grip, and vigorimetry compared to the uninjured side. The median patient satisfaction score was 6.6/10. Hand function using the DASH score was 9.5. Grip strength on the Jamar Dynamometer showed only a slight reduction of 13% compared to the uninjured side. The resultant force of the operated fingers on the vigorimeter is almost 60% of that of the contralateral side, and the finger-palm distance of the operated finger was reduced from 2.2 cm to 1.45 cm. Other functional scores, such as Krimmer (82.2) and Buck-Gramcko (10.9), support these good results. The follow-up of patients more than 4.5 years after reconstruction of the A2 and A3 flexor tendon pulley using the double- or triple-loop technique showed acceptable patient satisfaction and good function of the finger in everyday life.

description: In der vorliegenden, explorativen Forschungsarbeit sollten die Herausforderungen geflüchteter Jugendlichen im Integrationsprozess der Schweiz, insbesondere in Bezug auf Rassismus- und Diskriminierungserfahrungen erforscht werden. Damit ein Gesamtbild zur Lebenssituation von geflüchteten Jugendlichen entsteht, werden die Entwicklungsaufgaben im Jugendalter sowie die Flucht und die damit verbundenen Herausforderungen erläutert. Dabei spielen die Ziele der Integrationsagenda Schweiz, die von den kantonalen Integrationsprogrammen umgesetzt werden, eine essenzielle Rolle. Zuletzt wird auf das Thema Rassismus und Diskriminierung in der Schweiz eingegangen. Insgesamt wurden sechs geflüchtete Jugendliche anhand eines Leitfadeninterviews befragt und die daraus entstandenen Informationen durch die inhaltlich strukturierende qualitative Inhaltsanalyse nach Kuckartz und Rädiker ausgewertet. Die Ergebnisse zeigen, dass Jugendliche vor allem das Lernen der deutschen Sprache als herausfordernd empfanden. Durch die Wohnumstände in Durchgangs- und Asylzentren, den Aufenthaltsstatus sowie Rassismus- und Diskriminierungserfahrungen wurde die Integration erschwert. Demzufolge sollten die Jugendlichen eine intensivere und auf ihre Bedürfnisse ausgerichtete Betreuung durch die Fachpersonen erhalten. Ebenfalls sollten mehr Beschwerdemöglichkeiten für erlebte Rassismus- und Diskriminierungserfahrungen geschaffen werden. Aus diesen Aspekten erschliesst sich der Titel der vorliegenden Bachelorarbeit: ,,Herausforderungen von geflüchteten Jugendlichen im Integrationsprozess – Eine explorative Forschungsarbeit zu Rassismus- und Diskriminierungserfahrungen im Kanton Schwyz’’.

description: We present ~47,000 periodic variables found during the analysis of 5.4 million variable star candidates within a 20,000 square degree region covered by the Catalina Surveys Data Release-1 (CSDR1). Combining these variables with type-ab RR Lyrae from our previous work, we produce an on-line catalog containing periods, amplitudes, and classifications for ~61,000 periodic variables. By cross-matching these variables with those from prior surveys, we find that > 90% of the ~8,000 known periodic variables in the survey region are recovered. For these sources we find excellent agreement between our catalog and prior values of luminosity, period and amplitude, as well as classification. We investigate the rate of confusion between objects classified as contact binaries and type-c RR Lyrae (RRc's) based on periods, colours, amplitudes, metalicities, radial velocities and surface gravities. We find that no more than few percent of these variables in these classes are misidentified. By deriving distances for this clean sample of ~5,500 RRc's, we trace the path of the Sagittarius tidal streams within the Galactic halo. Selecting 146 outer-halo RRc's with SDSS radial velocities, we confirm the presence of a coherent halo structure that is inconsistent with current N-body simulations of the Sagittarius tidal stream. We also find numerous long-period variables that are very likely associated within the Sagittarius tidal streams system. Based on the examination of 31,000 contact binary light curves we find evidence for two subgroups exhibiting irregular lightcurves. One subgroup presents significant variations in mean brightness that are likely due to chromospheric activity. The other subgroup shows stable modulations over more than a thousand days and thereby provides evidence that the O'Connell effect is not due to stellar spots.

description: The distribution of various interstellar gas components and the pressure in the interstellar medium (ISM) is a result of the interplay of different dynamical mechanisms and energy sources on the gas in the Milky Way. The scale heights of the different gas tracers, such as HI and CO, are a measure of these processes. The scale height of [CII] emission in the Galactic plane is important for understanding those ISM components not traced by CO or HI. We determine the average distribution of [CII] perpendicular to the plane in the inner Galactic disk and compare it to the distributions of other key gas tracers, such as CO and HI. We calculated the vertical, z, distribution of [CII] in the inner Galactic disk by adopting a model for the emission that combines the latitudinal, b, spectrally unresolved BICE survey, with the spectrally resolved $Herschel$ Galactic plane survey of [CII] at b = 0 deg. Our model assumed a Gaussian emissivity distribution vertical to the plane, and related the distribution in z to that of the latitude b using the spectrally resolved [CII] Herschel survey as the boundary solution for the emissivity at b=0 deg. We find that the distribution of [CII] perpendicular to the plane has a full-width half-maximum of 172 pc, larger than that of CO, which averages ~110 pc in the inner Galaxy, but smaller than that of HI, ~230 pc, and is offset by -28 pc. We explain the difference in distributions of [CII], CO, and HI as due to [CII] tracing a mix of ISM components. Models of hydrostatic equilibrium of clouds in the disk predict different scale heights, for the same interstellar pressure. The diffuse molecular clouds with [CII] but no CO emission likely have a scale height intermediate between the low density atomic hydrogen HI clouds and the dense CO molecular clouds.

description: Ericksen and Leslie proposed a hydrodynamic model for liquid crystals in the format of conservation laws in the 1960s. Their original model includes inertial and compressibility effects, which makes the model a coupled parabolic-hyperbolic system. In this paper we build up the connection between the compressible and incompressible parabolic-hyperbolic liquid crystal model in the framework of classical solutions. We first derive the scaled Ericksen-Leslie system with dimensionless numbers, including Mach, Reynolds, and Ericksen numbers. In particular, we introduce the so-called inertial constant $χ$ which characterizes the inertial effect of the liquid crystal molecular. Next, we establish the energy estimates uniform in the Mach number $ε$ for both the compressible system and its time-derivative system with small data. Then, we pass to the limit $ε\rightarrow 0$ in the compressible system, so that we establish the global classical solution of the incompressible system by the compactness arguments. Moreover, we also obtain the convergence rates associated with $L^2$-norm in the case of well-prepared initial data. This is the first result on the incompressible limit of the compressible parabolic-hyperbolic liquid crystal model and confirms the relations of different parabolic-hyperbolic liquid crystal model rigorously.

Efficient Baseline-free Sampling in Parameter Exploring Policy Gradients: Super Symmetric PGPE

Year: 2013
Subjects: subject: Machine Learning (cs.LG)
subject: FOS: Computer and information sciences

description: Policy Gradient methods that explore directly in parameter space are among the most effective and robust direct policy search methods and have drawn a lot of attention lately. The basic method from this field, Policy Gradients with Parameter-based Exploration, uses two samples that are symmetric around the current hypothesis to circumvent misleading reward in \emph{asymmetrical} reward distributed problems gathered with the usual baseline approach. The exploration parameters are still updated by a baseline approach - leaving the exploration prone to asymmetric reward distributions. In this paper we will show how the exploration parameters can be sampled quasi symmetric despite having limited instead of free parameters for exploration. We give a transformation approximation to get quasi symmetric samples with respect to the exploration without changing the overall sampling distribution. Finally we will demonstrate that sampling symmetrically also for the exploration parameters is superior in needs of samples and robustness than the original sampling approach.

Topological Model for Domain Walls in (Super-)Yang-Mills Theories

description: We derive a topological action that describes the confining phase of (Super-)Yang-Mills theories with gauge group $SU(N)$, similar to the work recently carried out by Seiberg and collaborators. It encodes all the Aharonov-Bohm phases of the possible non-local operators and phases generated by the intersection of flux tubes. Within this topological framework we show that the worldvolume theory of domain walls contains a Chern-Simons term at level $N$ also seen in string theory constructions. The discussion can also illuminate dynamical differences of domain walls in the supersymmetric and non-supersymmetric framework. Two further analogies, to string theory and the fractional quantum Hall effect might lead to additional possibilities to investigate the dynamics.

description: We present the experimental demonstration of the parallel parametric generation of spin-waves in a microscaled yttrium iron garnet waveguide with nanoscale thickness. Using Brillouin light scattering microscopy, we observe the excitation of the first and second waveguide modes generated by a stripline microwave pumping source. Micromagnetic simulations reveal the wave vector of the parametrically generated spin-waves. Based on analytical calculations, which are in excellent agreement with our experiments and simulations, we prove that the spin-wave radiation losses are the determinative term of the parametric instability threshold in this miniaturized system. The used method enables the direct excitation and amplification of nanometer spin-waves dominated by exchange interactions. Our results pave the way for integrated magnonics based on insulating nano-magnets.

description: Geflüchtete Menschen mit B- oder F-Ausweis halten sich oft für längere Zeit in der Schweiz auf, besitzen jedoch kein aktives und passives Wahlrecht. Diese Arbeit analysiert, welche politischen und rechtlichen Grundlagen in der Schweiz für Menschen mit Fluchterfahrung für die politische Partizipation bestehen, was Hindernisse und Ressourcen für die politische Beteiligung darstellen und welche Handlungsprinzipien für soziokulturelle Animator*innen dabei zu beachten sind. Im Anschluss wird durch die Autorin Tamara Fischer aufgezeigt, welche Handlungsmassnahmen von soziokulturellen Animator*innen empfehlenswert sind, um die politische Partizipation der Zielgruppe zu stärken. Die Verfasserin der Bachelorarbeit arbeitete selbst als Integrationsbeauftragte in einer Gemeinde und kennt die Bedürfnisse der Geflüchteten sowie die strukturellen Hürden, die für sie bestehen. Mit dieser Arbeit möchte sie Fachpersonen aufzeigen, wie sie Menschen mit Fluchtgeschichte ermächtigen können, ihre Position zu reflektieren und sich politisch zu beteiligen. Die Fachliteraturarbeit zeigt, dass für die politische Partizipation in der Schweiz die Willkommenskultur der Schweiz und den Entscheidungstragenden und das Aufzeigen der Chancenungleichheit seitens der Fachpersonen der soziokulturellen Animation zentral ist. Weiter wurde aufgezeigt, dass nicht eine Massnahme allein die Situation für die Zielgruppe verändert, sondern dass sich für die verschiedenen Probleme unterschiedliche Lösungen und Handlungsmassnahmen anbieten. Für viele Handlungsmassnahmen wurde im Anhang eine Liste mit weiterführenden Beispielen und Websites zusammengestellt.

description: The alternating current (ac) Josephson effect in a time-independent spatially-inhomogeneous setting is manifested by the occurrence of Josephson oscillations - periodic macroscopic phase-induced collective motions of the quantum condensate. So far, this phenomenon was observed at cryogenic temperatures in superconductors, in superfluid helium, and in Bose-Einstein condensates (BECs) of trapped atoms. Here, we report on the discovery of the ac Josephson effect in a magnon BEC carried by a room-temperature ferrimagnetic film. The BEC is formed in a parametrically populated magnon gas in the spatial vicinity of a magnetic trench created by a dc electric current. The appearance of the Josephson effect is manifested by oscillations of the magnon BEC density in the trench, caused by a coherent phase shift between this BEC and the BEC in the nearby regions. Our findings advance the physics of room-temperature macroscopic quantum phenomena and will allow for their application for data processing in magnon spintronics devices.

description: In this work, we study the fractal and multifractal properties of a family of fractal networks introduced by Gallos {\it et al.} ({\it Proc. Natl. Acad. Sci. U.S.A.}, 2007, {\bf 104}: 7746). In this fractal network model, there is a parameter $e$ which is between $0$ and $1$, and allows for tuning the level of fractality in the network. Here we examine the multifractal behavior of these networks, dependence relationship of fractal dimension and the multifractal parameters on the parameter $e$. First, we find that the empirical fractal dimensions of these networks obtained by our program coincide with the theoretical formula given by Song {\it et al.} ( {\it Nat. Phys}, 2006, {\bf 2}: 275). Then from the shape of the $τ(q)$ and $D(q)$ curves, we find the existence of multifractality in these networks. Last, we find that there exists a linear relationship between the average information dimension $$ and the parameter $e$.

description: Fusion data for $^{48}$Ca+$^{90,96}$Zr are analyzed by coupled-channels calculations that are based on the M3Y+repulsion, double-folding potential. By applying a previously determined nuclear density of $^{48}$Ca, the neutron densities of the zirconium isotopes are adjusted to optimize the fit to the fusion data, whereas the proton densities are determined by electron scattering experiments. It is shown that the fusion data can be explained fairly well by including couplings to one- and two-phonon excitations of the reacting nuclei and to one- and two-nucleon transfer reactions but there is also some sensitivity to multiphonon excitations. The neutron skin thicknesses extracted for the two zirconium isotopes are consistent with anti-proton measurements. The densities of the zirconium isotopes are used together with the previously determined nuclear density of $^{40}$Ca to calculate the M3Y+repulsion potentials and predict the fusion cross sections of $^{40}$Ca+$^{90,96}$Zr. The predicted cross sections for $^{40}$Ca+$^{90}$Zr are in reasonable agreement with the data when the influence of multiphonon excitations and a modest transfer is considered. The prediction of the $^{40}$Ca+$^{96}$Zr fusion cross section, on the other hand, is poor and under-predicts the data by 30 to 40%. Although couplings to transfer channels with positive $Q$ values were expected to play an important role, they are not able to explain the data, primarily because the predicted Coulomb barrier is about 1.5 MeV too high. Possible reasons for this failure are discussed.

description: Nowadays, the interaction between phonon and magnon subsystems of a magnetic medium is a hot topic of research. The complexity of phonon and magnon spectra, the existence of both bulk and surface modes, the quantization effects, and the dependence of magnon properties on applied magnetic field, make this field very complex and intriguing. Moreover, the recent advances in the fields of spin-caloritronics and magnon spintronics as well as the observation of the spin Seebeck effect (SSE) in magnetic insulators points on the crucial role of magnons in spin-caloric transport processes. In this review, we collect the variety of different studies in which magnon-phonon interaction play important role. The scope of the paper covers the wide range of phenomena starting from the interaction of the coherent magnons with surface acoustic wave and finishing with the formation of magnon supercurrents in the thermal gradients.

description: We study the spectrum of vector mesons in a finite temperature plasma. The plasma is holographically described by a black hole AdS/QCD model. We compute the boundary retarded Green's function using AdS/CFT prescriptions. The corresponding thermal spectral functions show quasiparticle peaks at low temperatures. Then we calculate the quasinormal modes of vector mesons in the soft-wall black hole geometry and analyse their temperature and momentum dependences.

description: Durch den digitalen Wandel und die damit verbundenen technologischen Fortschritte hat sich das mediale Nutzungsverhalten von Jugendlichen verändert und die Entstehung von neuen sexualbezogenen Phänomenen im virtuellen Raum ist begünstigt worden. Sexting ist eines dieser Phänomene und bezeichnet den privaten und freiwilligen Austausch von erotischem Bild- und Videomaterial. Medial in Erscheinung trat der Begriff vor zirka 15 Jahren, als missbräuchlich weitergeleitete und veröffentlichte Sexts schwerwiegende Folgen für junge Menschen hatten. Dies führte zu einem wissenschaftlichen und öffentlichen Diskurs, der die Risiken von Sexting in den Vordergrund stellte und es als abweichendes Verhalten klassifizierte. Mit der vorliegenden Arbeit wird aufgezeigt, dass Sexting in der heutigen Lebenswelt von Jugendlichen zentral ist und es sich dabei nicht um eine Abnormalität, sondern um eine Strategie handelt, um ganz unterschiedliche motivierte Bedürfnisse zu befriedigen. Die Risiken, die sich durch die Praktizierung von Sexting ergeben können, werden dabei nicht ausgeblendet, jedoch wird eine lebensweltorientierte Herangehensweise an die Thematik gewählt, in der es die Jugendlichen in einer selbstbestimmten Sexualität zu befähigen gilt. Dafür werden wichtige Aspekte aufgezeigt, die für ein professionelles Handeln der Sozialen Arbeit berücksichtigt werden müssen, wie die Aufklärung im digitalen Zeitalter, erforderliche (Medien-)Kompetenzen und sinnvolle Präventionsansätze. Am Schluss wird auf die Verantwortlichkeiten der Sozialen Arbeit eingegangen, die sich im Umgang mit Jugendlichen, die Sexting betreiben, ergeben und so wird die zentrale Fragestellung der vorliegenden Literaturarbeit beantwortet.

description: We show that the (gauge fixed) classical action of the Color Glass Condensate is invariant under a suitable Becchi-Rouet-Stora-Tyutin symmetry, that holds after the gluon modes are split into their fast, semi-fast and soft components, according to the longitudinal momenta they carry. This entails the existence of a corresponding Slavnov-Taylor identity which in turn strongly constrains the effective field theory arising when integrating out the semi-fast modes. Specifically, we prove that this identity guarantees the gauge invariance of the resulting effective theory. In addition, we use it to demonstrate that the integration over the semi-fast modes does not deform the classical Yang-Mills equations of motion, thus validating a key assumption in the usual procedure adopted when deriving the renormalization group equation governing the evolution with energy of the effective theory. As far as the latter are concerned, we finally prove that its functional form is common, and it is determined by symmetries arguments alone. The formal properties of these equations valid in different regimes and/or approximations (e.g., the JIMWLK equation and its BFKL limit) can be therefore derived in a unified setting within this algebraic approach.

description: The study of military innovation is one of the most important topics in the strategic studies arena, but when it comes to defining the term ‘military innovation,’ there is a remarkable lack of consensus. Lack of agreement on a definition makes it harder to advance knowledge beyond specific cases and for ongoing research to have policy relevance. Currently, what one might consider an innovation another might call an adaptation of an existing technology or tactic, or neither. To move forward, we survey dozens of existing studies and review articles for proposed definitions and examples of military innovation. We locate common and differentiating themes across a wide range of definitions and (at times) conflicting conceptual terminology. We then propose a new framework for thinking about military innovation that builds on existing research and suggests a path forward for future research. Finally, in an online appendix, we demonstrate the plausibility of the framework applied to prominent cases.

description: By studying global AdS using different foliations, global and Rindler-AdS, we show that there are two different asymptotic Fefferman-Graham expansions possible and thus two different definitions of "boundaries". We demonstrate that imposing boundary conditions on the two boundaries is not mutually compatible even when these boundaries are pushed to infinity. Thus, these two procedures define two genuinely distinct theories that we call global-CFT and Rindler-CFT. We show that the Rindler-CFT is not the same as the theory one gets by "Rindlerizing the global-CFT" as described in hep-th/9804085. We conjecture that the Rindler theory is incapable of capturing the dynamics inside the horizon and discuss its implications for the BTZ-CFT duality proposed in hep-th/0106112.
