description: We investigate the gas-phase metallicity and Lyman Continuum (LyC) escape fraction of a strongly gravitationally lensed, extreme emission-line galaxy at z=3.417, J1000+0221S, recently discovered by the CANDELS team. We derive ionization and metallicity sensitive emission-line ratios from H+K band LBT/LUCI medium resolution spectroscopy. J1000+0221S shows high ionization conditions, as evidenced by its enhanced [OIII]/[OII] and [OIII]/Hbeta ratios. Consistently, strong-line methods based on the available line ratios suggest that J1000+0221S is an extremely metal-poor galaxy, with a metallicity of 12+log(O/H) < 7.44 (< 5% solar), placing it among the most metal-poor star-forming galaxies at z > 3 discovered so far. In combination with its low stellar mass (2x10^8 Msun) and high star formation rate (5 Msun/yr), the metallicity of J1000+0221S is consistent with the extrapolation to low masses of the mass-metallicity relation traced by Lyman-break galaxies at z > 3, but it is 0.55 dex lower than predicted by the fundamental metallicity relation at z < 2.5. These observations suggest the picture of a rapidly growing galaxy, possibly fed by the massive accretion of pristine gas. Additionally, deep LBT/LBC in the UGR bands are used to derive a limit to the LyC escape fraction, thus allowing us to explore for the first time the regime of sub-L* galaxies at z > 3. We find a 1sigma upper limit to the escape fraction of 23%, which adds a new observational constraint to recent theoretical models predicting that sub-L* galaxies at high-z have high escape fractions and thus are the responsible for the reioization of the Universe.

description: We study quantum interference effects in a two-dimensional chiral metal (bipartite lattice) with vacancies. We demonstrate that randomly distributed vacancies constitute a peculiar type of chiral disorder leading to strong modifications of critical properties at zero energy as compared to conventional chiral metals. In particular, the average density of states diverges as $ρ\propto E^{-1} |\ln E|^{-3/2}$ and the correlation length $L_c \propto \sqrt{|\ln E|}$ in the limit $E \to 0$. When the average density of vacancies is different in the two sublattices, a finite concentration of zero modes emerges and a gap in the quasiclassical density of states opens around zero energy. Interference effects smear this gap resulting in exponentially small tails at low energies.

description: Time- and angle-resolved extreme ultraviolet photoemission spectroscopy is used to study the electronic structure dynamics in BaFe$_2$As$_2$ around the high-symmetry points $Γ$ and $M$. A global oscillation of the Fermi level at the frequency of the $A_{1g}$(As) phonon mode is observed. It is argued that this behavior reflects a modulation of the effective chemical potential in the photoexcited surface region that arises from the high sensitivity of the band structure near the Fermi level to the $A_{1g}$ phonon mode combined with a low electron diffusivity perpendicular to the layers. The results establish a novel way to tune the electronic properties of iron pnictides: coherent control of the effective chemical potential. The results further suggest that the equilibration time for the effective chemical potential needs to be considered in the ultrafast electronic structure dynamics of materials with weak interlayer coupling.

description: A theoretical approach for characterising the influence of asymmetry of noise distribution on the escape rate of a multi-stable system is presented. This was carried out via the estimation of an action, which is defined as an exponential factor in the escape rate, and discussed in the context of full counting statistics paradigm. The approach takes into account all cumulants of the noise distribution and demonstrates an excellent agreement with the results of numerical simulations. An approximation of the third order cumulant was shown to have limitations on the range of dynamic stochastic system parameters. The applicability of the theoretical approaches developed so far is discussed for an adequate characterisation of the escape rate measured in experiments.

description: An autonomous decentralized distributed generation hybrid system supplies electricity to the user load both in grid tied or standalone modes. This kind of decentralized system is frequently located in remote and inaccessible areas. It is essential for about one third of the world populations who are living in undeveloped or isolated regions and have no access to utility grid. Most people live in remote and rural areas, with low population density, lacking even the basic infrastructure. The grid extension to these locations might not be cost effective option and sometimes technically not feasible even. This decentralized energy generation system is essential for countries which has low installed capacity.
title: Grounded Theory: The Moral Order of Cannabis Hemp in Canada
Creators: name: Slinger, Matthew P.
Publisher: name: Capilano University
Year: 2018

description: Cannabis legalization is coming to Canada in 2018. The Liberal government in Canada has promised to follow through on their campaign policy of legalizing cannabis after seeing a strong demand from the public for a change in drug laws. The troubling reality is that it has taken the Canadian government a suspiciously long time to draft legislation that continues to operate off an ambiguous, speculative, and unsubstantiated framework. The present paper argues that CBC and CTV News are agenda setting outlets in the context of cannabis legalization in Canada. To understand our moral order, this paper explores the media representation of laws, rules, and regulations being drafted and the research being conducted for cannabis legalization. The proposed legislation excludes critical information every Canadian citizen needs to know about the cannabis hemp plant, information that empowers the public, discredits the government’s discourse on cannabis, and threatens the agendas of many corporations and industries.

description: We study a number of (3+1)- and (2+1)-dimensional defect and boundary conformal field theories holographically dual to supergravity theories. In all cases the defects or boundaries are planar, and the defects are codimension-one. Using holography, we compute the entanglement entropy of a (hemi-)spherical region centered on the defect (boundary). We define defect and boundary entropies from the entanglement entropy by an appropriate background subtraction. For some (3+1)-dimensional theories we find evidence that the defect/boundary entropy changes monotonically under certain renormalization group flows triggered by operators localized at the defect or boundary. This provides evidence that the g-theorem of (1+1)-dimensional field theories generalizes to higher dimensions.

title: Multidecadal Data Demonstrate the Role of Climate and Natural History Traits in Shaping Butterfly Phenology
Creators: name: Reis, Gbolahan Anthony
Publisher: name: Utah State University
Year: 2024

description: Climate change is transforming the natural world, altering the timing of key events in the lives of plants and animals, such as when flowers bloom or when butterflies take flight. These timing changes, known as phenology shifts, can disrupt ecosystems and species interactions, creating ripple effects through food webs and biodiversity. While scientists have studied these shifts for decades, much of the focus has been on simple metrics, like the first or last day a butterfly is seen flying each year. However, these measures do not tell the whole story of how climate change is impacting the entire flight season or even why different species respond in different ways.
In this study, we used decades of butterfly observations from five mountain sites in California to explore how climate affects butterfly flight seasons. By examining 135 butterfly species across sites ranging from low to high elevations, we looked at how temperature and precipitation influence their flight periods.
We found that climate has complex effects on butterflies. Warmer daytime spring temperatures made butterflies fly earlier across all elevations, while snowy winters delayed their activity in areas with a substantial amount of snowfall. Even small changes in nighttime spring temperatures significantly shifted the timing of their flight seasons.
Interestingly, not all species responded to climate in the same way. We saw large differences in how climate affected butterflies. Differences in their natural history traits, like how many generations a species has per year (voltinism), what types of plants their caterpillars feed on (diet breadth), and the life stage at which they survive the winter (overwintering stage) do not fully explain these variations in the effect of climate.
Our research highlights the need to study the full flight season of butterflies, not just isolated moments, to better understand how they are being impacted by climate change. These insights can help conservationists make smarter decisions about protecting butterflies and the ecosystems they support, ensuring we’re better prepared to address the challenges of a warming world.

description: Electron spin relaxation in a spin-polarized quantum Hall state is studied. Long spin relaxation times that are at least an order of magnitude longer than those measured in previous experiments were observed and explained within the spin-exciton relaxation formalism. Absence of any dependence of the spin relaxation time on the electron temperature and on the spin-exciton density, and specific dependence on the magnetic field indicate the definite relaxation mechanism -- spin-exciton annihilation mediated by spin-orbit coupling and smooth random potential.

description: Las Antillas albergan una diversidad de libélulas, muchas endémicas. Desafortunadamente, el conocimiento en Puerto Rico es limitado y tener un listado de especies es un primer paso en el estudio de este grupo. Por tanto, el objetivo de este trabajo es generar una lista actualizada de especies en Puerto Rico utilizando censos, publicaciones, y colecciones, y luego comparar la diversidad de la isla con otras en el Caribe como método de evaluar el estado de conocimiento. Las primeras listas publicadas en los años 40 por Julio García-Díaz y Elsie Klotz para la isla reportan cerca de 40 especies, mientras que la lista publicada en el 2013 por François Meurgey reduce el número a 36 especies. En contraste, nuestra lista resultó en 48 especies. En comparación a las listas iniciales, 8 especies fueron añadidas (p.ej. Triacanthagyna caribbea y Dythemis rufinervis). En comparación a la lista de Meurgey, 12 especies fueron añadidas (p.ej. Tauriphila australis y Erythrodiplax berenice). Puerto Rico, a diferencia de otras islas en el Caribe, no tiene endémicas, pero alberga 7 endémicas a las Antillas. Afortunadamente, ninguna de estas ha sido clasificada como vulnerable o en peligro de extinción. Sin embargo, la alta presencia humana en la isla podría ser una amenaza para estas especies en Puerto Rico. Entre los vacíos de información, resalta la necesidad de entender como actividades antropogénicas (p.ej. urbanización) y otras formas de desarrollo en la isla podrían estar afectando las especies de Odonata. Además, se necesita información sobre la distribución de especies y su correspondencia con las áreas protegidas.
On adaptive timestepping for weakly instationary solutions of hyperbolic conservation laws via adjoint error control

Publisher: name: arXiv
Year: 2014
Subjects: subject: Numerical Analysis (math.NA)

description: We study a recent timestep adaptation technique for hyperbolic conservation laws. The key tool is a space-time splitting of adjoint error representations for target functionals due to Süli and Hartmann. It provides an efficient choice of timesteps for implicit computations of weakly instationary flows. The timestep will be very large in regions of stationary flow, and become small when a perturbation enters the flow field. Besides using adjoint techniques which are already well-established, we also add a new ingredient which simplifies the computation of the dual problem. Due to Galerkin orthogonality, the dual solution ϕ does not enter the error representation as such. Instead, the relevant term is the difference of the dual solution and its projection to the finite element space, ϕ-ϕh . We can show that it is therefore sufficient to compute the spatial gradient of the dual solution, $w = {\nabla} ϕ$. This gradient satisfies a conservation law instead of a transport equation, and it can therefore be computed with the same algorithm as the forward problem, and in the same finite element space. We demonstrate the capabilities of the approach for a weakly instationary test problem for scalar conservation laws.

description: Quenched central galaxies tend to reside in a preferentially quenched large-scale environment, a phenomenon that has been dubbed galactic conformity. Remarkably, this tendency persists out to scales far larger than the virial radius of the halo hosting the central. Therefore, conformity manifestly violates the widely adopted assumption that the dark matter halo mass Mvir exclusively governs galaxy occupation statistics. This paper is the first in a series studying the implications of the observed conformity signal for the galaxy-dark matter connection. We show that recent measurements of conformity on scales R ~1-5 Mpc imply that central galaxy quenching statistics cannot be correctly predicted with the knowledge of Mvir alone. We also demonstrate that ejected (or `backsplash') satellites cannot give rise to the signal. We then invoke the age matching model, which is predicated on the co-evolution of galaxies and halos. We find that this model produces a strong signal, and that central galaxies are solely responsible. We conclude that large-scale `2-halo' conformity represents a smoking gun of central galaxy assembly bias, and indicates that contemporary models of satellite quenching have systematically over-estimated the influence of post-infall processes.

Overexposing Florence

Publisher: name: No Publisher Supplied
Year: 2018

description: This dissertation examines the many ways in which urban form and visual media interact in 19th-, 20th-, and 21st-centuries Florence. More in detail, this work analyzes photographs of Florence’s medieval and Renaissance heritage by the Alinari Brothers atelier (1852-1890), and then retraces these photographs’ relationship to contemporary visual culture – namely through representations of Florence in international cinema, art photography, and the guidebook – as well as to the city’s actual structure. Unlike previous scholarship, my research places the Alinari Brothers’ photographs in the context of the enigmatic processes of urban modernization that took place in Florence throughout the 19th century, changing its medieval structure into that of a modern city and the capital of newly unified Italy from 1865 to 1871. The Alinari photographs’ tension between the establishment of the myth of Florence as the cradle of the Renaissance and an uneasy attitude towards modernization, both cherished and feared, produced a multi-layered city portrait, which raises questions about crucial issues such as urban heritage preservation, mass tourism, (de)industrialization, social segregation, and real estate speculation. These questions remain unresolved in contemporary Florence, and my dissertation explores them by following the influence of the Alinari’s photographic gaze on contemporary representations of Florence in international cinema (Brian De Palma, Dario Argento, James Ivory, Ridley Scott), art and tourism photography (Gianni Berengo Gardin, Luigi Ghirri, Olivo Barbieri, Martin Parr, guidebooks by Italian Touring Club, Fodor and Frommer), and their relationship to contemporary urban development. Ultimately, my work aims to redefine the relevance of early photography as a unique tool for understanding contemporary urban space and its representation, thanks to its capacity to expose the contradictions of the present and look into the city’s future.

description: In recent years, new coronagraphic schemes have been proposed, the most promising being the optical vortex phase mask coronagraphs. In our work, a new scheme of broadband optical scalar vortex coronagraph is proposed and characterized experimentally in the laboratory. Our setup employs a pair of computer generated phase gratings (one of them containing a singularity) to control the chromatic dispersion of phase plates and achieves a constant peak-to-peak attenuation below 1:1000 over a bandwidth of 120 nm centered at 700 nm. An inner working angle of $λ$/D is demonstrated along with a raw contrast of 11.5\,magnitudes at 2$λ$/D. A more compact setup achieves a peak-to-peak attenuation below 1:1000 over a bandwidth of 60 nm with the other results remaining the same.

description: Density-functional-theory (DFT) calculations have been performed on the Li-Si and Li-Ge systems. Lithiated Si and Ge, including their metastable phases, play an important technological rôle as Li-ion battery (LIB) anodes. The calculations comprise structural optimisations on crystal structures obtained by swapping atomic species to Li-Si and Li-Ge from the X-Y structures in the International Crystal Structure Database, where X={Li,Na,K,Rb,Cs} and Y={Si,Ge,Sn,Pb}. To complement this at various Li-Si and Li-Ge stoichiometries, ab initio random structure searching (AIRSS) was also performed. Between the ground-state stoichiometries, including the recently found Li$_{17}$Si$_{4}$ phase, the average voltages were calculated, indicating that germanium may be a safer alternative to silicon anodes in LIB, due to its higher lithium insertion voltage. Calculations predict high-density Li$_1$Si$_1$ and Li$_1$Ge$_1$ $P4/mmm$ layered phases which become the ground state above 2.5 and 5 GPa respectively and reveal silicon and germanium's propensity to form dumbbells in the Li$_x$Si, $x=2.33-3.25$ stoichiometry range. DFT predicts the stability of the Li$_{11}$Ge$_6$ $Cmmm$, Li$_{12}$Ge$_7$ $Pnma$ and Li$_7$Ge$_3$ $P32_12$ phases and several new Li-Ge compounds, with stoichiometries Li$_5$Ge$_2$, Li$_{13}$Ge$_5$, Li$_8$Ge$_3$ and Li$_{13}$Ge$_4$.

description: We consider a self-interacting, massive scalar field (non)minimally coupled to new massive gravity in three dimensions. For this model, we first derive a family of black hole solutions depending on a unique integration constant and parameterized in terms of the nonminimal coupling parameter. Imposing the absence of naked singularities restricts the parameters in such a way that the field vanishes at infinity and fixes the metric to be asymptotically AdS. Within this family of solutions it is possible to find a black hole supported by a minimally coupled scalar field and therefore the existence of these solutions is not inherent to the presence of the nonminimal coupling. The Wald formula for the entropy, being proportional to the lapse function evaluated at the horizon, yields a zero entropy in spite of the fact that the solution has a non zero temperature. As a consequence, the unique integration constant may be interpreted as a sort of gravitational hair. As in the source free case, we show that the same field equations admit as well asymptotically Lifshitz black hole solutions in a different region of the space of parameters. These Lifshitz solutions are divided in three families for which all the parameters entering in the action may be expressed in term of the dynamical exponent.

description: Despite female-lead films being more prevalent in Hollywood than ever, media coming out of the mainstream continues to construct women from the male gaze. Films that falsely claim to escape this gaze work against feminist equality, leaving audiences desperate for content that both promotes diverse representation and also fulfills a new gaze. This paper will first define the concepts of the male and female gaze and discuss the theorists behind them. It will then assess, using film examples, the divergence between the female gaze and Hollywood “female-lead” films. Finally, it will show how the female gaze looks when it is both genuinely understood and applied.

description: We present J, H, CH_4 short (1.578 micron), CH_4 long (1.652 micron) and K_s-band images of the dust ring around the 10 Myr old star HR 4796 A obtained using the Near Infrared Coronagraphic Imager (NICI) on the Gemini-South 8.1 meter Telescope. Our images clearly show for the first time the position of the star relative to its circumstellar ring thanks to NICI's translucent focal plane occulting mask. We employ a Bayesian Markov Chain Monte Carlo method to constrain the offset vector between the two. The resulting probability distribution shows that the ring center is offset from the star by 16.7+/-1.3 milliarcseconds along a position angle of 26+/-3 degrees, along the PA of the ring, 26.47+/-0.04 degrees. We find that the size of this offset is not large enough to explain the brightness asymmetry of the ring. The ring is measured to have mostly red reflectivity across the JHK_s filters, which seems to indicate micron-sized grains. Just like Neptune's 3:2 and 2:1 mean-motion resonances delineate the inner and outer edges of the classical Kuiper Belt, we find that the radial extent of the HR 4796 A and Fomalhaut rings could correspond to the 3:2 and 2:1 mean-motion resonances of hypothetical planets at 54.7 AU and 97.7 AU in the two systems, respectively. A planet orbiting HR 4796 A at 54.7 AU would have to be less massive than 1.6 Mjup so as not to widen the ring too much by stirring.

To charactize its large-scale structure, we derived column density and temperature maps using PACS and SPIRE observations from the Herschel Gould Belt Survey, and applied several tools, such as filament tracing, power-spectra, Δ-variance, and probability distribution functions of column density (PDFs), to derive physical properties. The column density maps reveal a different morphological appearance for the three clouds, with a ridge-like structure for Cha I, a clump-dominated regime for Cha II, and an intricate filamentary network for Cha III. The filament width is measured to be around 0.12\pm0.04 pc in the three clouds, and the filaments found to be gravitationally unstable in Cha I and II, but mostly subcritical in Cha III. Faint filaments (striations) are prominent in Cha I showing a preferred alignment with the large-scale magnetic field. The PDFs of all regions show a lognormal distribution at low column densities. For higher densities, the PDF of Cha I shows a turnover indicative of an extended higher density component, culminating with a power-law tail. Cha II shows a power-law tail with a slope characteristic of gravity. The PDF of Cha III can be best fit by a single lognormal. The turbulence properties of the three regions are found to be similar, pointing towards a scenario where the clouds are impacted by large-scale processes. The magnetic field could possibly play an important role for the star-formation efficiency in the Chamaeleon clouds if proven that it can effectively channel material on Cha I, and possibly Cha II, but probably less efficiently on the quiescent Cha III cloud.

description: Covid-19 has had a seismic impact on the world and one which continues to reverberate. The pandemic has disrupted day-to-day living in the UK in ways arguably not seen since the Second World War. Research has begun to emerge marking the different ways in which groups and societies have experienced and responded to the Covid-19 pandemic. However, children have, for the most part, been left out of the conversation. Though not a homogenous group, children can be seen as possessing their own cultural knowledge. Yet, historically, children’s voices have been constrained and distorted by adults, either wilfully or not, through prejudicial attitudes and/or adult-centric bias. The present research recognises structural, epistemic injustices faced by children and positions children as best-placed to represent their understanding about the world. The present research sought to understand how children have constructed the Covid-19 pandemic in ways that respect them as rights-holders, autonomous individuals, and meaning-makers. Participatory approaches and constructivist grounded theory methods were used to facilitate more equitable research, with five child co-researchers devising many aspects of the methodology. Each co-researcher (age 9-10) was partnered with a younger pupil participant (age 6-7). Together, research partners integrated drawings with dialogue to co-generate a rich dataset comprising children’s constructions of the Covid-19 pandemic. Data were collected and analysed concurrently across two timepoints (July 2021 and November 2021), with dissemination discussions taking place in January 2022. Co-researchers engaged in constant comparative analysis to progressively sort and synthesise their data, and to inductively raise them to an abstract level. Through collaborative analysis, co-researchers ultimately raised five pivotal concepts from their data, which together formed a constructivist grounded theoretical framework. It comprises ideas about managing significant challenges and changes, while developing a sound knowledge base of their situations. The children’s final product, and the process by which their knowledge was generated, have important implications for Educational Psychology practice and epistemic conduct across wider society.
Model-independent determination of the magnetic radius of the proton from spectroscopy of ordinary and muonic hydrogen

description: To date the magnetic radius of the proton has been determined only by means of electron-proton scattering, which is not free of controversies. Any existing atomic determinations are irrelevant because they are strongly model-dependent. We consider a so-called Zemach contribution to the hyperfine interval in ordinary and muonic hydrogen and derive a self-consistent model-independent value of the magnetic radius of the proton. More accurately, we constrain not a value of the magnetic radius by itself, but its certain combination with the electric-charge radius of the proton, namely, R_E^2+R_M^2. The result from the ordinary hydrogen is found to be R_E^2+R_M^2=1.35(12) fm^2, while the derived muonic value is 1.49(18) fm^2. That allows us to constrain the value of the magnetic radius of proton R_M=0.78(8) fm at the 10% level.

description: We study a class of time evolution models that contain dissipation mech- anisms exhibited by geophysical materials during deformation: plasticity, viscous dissipation and fracture. We formally prove that they satisfy a Clausius-Duhem type inequality. We describe a semi-discrete time evolu- tion associated with these models, and report numerical 1D and 2D traction experiments, that illustrate that several dissipation regimes can indeed take place during the deformation. Finally, we report 2D numerical simulation of an experiment by Peltzer and Tapponnier, who studied the indentation of a layer of plasticine as an analogue model for geological materials.

description: We present the most recent precision electroweak measurements of single $W$ and $Z$ boson cross section and properties from the LHC and Tevatron colliders, analyzing data collected by ATLAS, CDF, CMS, D0, and LHCb detectors. The results include the measurement of the single $W$ and $Z$ boson cross section at LHC, the differential cross section measurements, the measurement of $W$ boson mass, the measurement of $W$ and $Z$ charge asymmetry. These measurements provide precision tests on the electroweak theory, high order predictions and the information can be used to constraint parton distribution functions.

description: The detection of strong thermochemical disequilibrium in the atmosphere of an extrasolar planet is thought to be a potential biosignature. In this article we present a new kind of false positive that can mimic a disequilibrium or any other biosignature that involves two chemical species. We consider a scenario where the exoplanet hosts a moon that has its own atmosphere and neither of the atmospheres is in chemical disequilibrium. Our results show that the integrated spectrum of the planet and the moon closely resembles that of a single object in strong chemical disequilibrium. We derive a firm limit on the maximum spectral resolution that can be obtained for both directly-imaged and transiting planets. The spectral resolution of even idealized space-based spectrographs that might be achievable in the next several decades is in general insufficient to break the degeneracy. Both chemical species can only be definitively confirmed in the same object if absorption features of both chemicals can be unambiguously identified and their combined depth exceeds 100%.

Computation of the Mean First-Encounter Time Between the Ends of a Polymer Chain

description: Using a novel theoretical approach, we study the mean first encounter time (MFET) between the two ends of a polymer. Previous approaches used various simplifications that reduced the complexity of the problem, leading, however to incompatible results. We construct here for the first time a general theory that allows us to compute the MFET. The method is based on estimating the mean time for a Brownian particle to reach a narrow domain in the polymer configuration space. In dimension two and three, we find that the MFET depends mainly on the first eigenvalue of the associated Fokker-Planck operator and provide precise estimates that are confirmed by Brownian simulations. Interestingly, although many time scales are involved in the encounter process, its distribution can be well approximated by a single exponential, which has several consequences for modeling chromosome dynamics in the nucleus. Another application of our result is computing the mean time for a DNA molecule to form a closed loop (when its two ends meet for the first time).

description: This paper discusses the CRISTAL object lifecycle management system and its use in provenance data management and the traceability of system events. This software was initially used to capture the construction and calibration of the CMS ECAL detector at CERN for later use by physicists in their data analysis. Some further uses of CRISTAL in different projects (CMS, neuGRID and N4U) are presented as examples of its flexible data model. From these examples, applications are drawn for the High Energy Physics domain and some initial ideas for its use in data preservation HEP are outlined in detail in this paper. Currently investigations are underway to gauge the feasibility of using the N4U Analysis Service or a derivative of it to address the requirements of data and analysis logging and provenance capture within the HEP long term data analysis environment.

Kompetente Beratung zur Alltagsbewältigung: Die sozialpädagogische Beratung von Menschen mit einer kognitiven Beeinträchtigung im stationären Setting
Creators: name: Jasmina, Spasovski
Publisher: name: Zenodo
Year: 2022

description: Beratung – ein eigenständiges Konstrukt im Hilfeverständnis –, kennen wir aus unserem Alltagsgebrauch in verschiedenen Facetten. Ob Raten, Rat-Geben, Rat-Nehmen, Rat- Losigkeit, Ratschluss oder ER-raten, BE-raten, ZU-raten, Miss-raten, An-raten, Ab-raten etc. finden sich viele Bedeutungen des Ratens, die eine interaktive Dimension gemeinsam haben. Demgemäss erscheinen unterschiedliche Beratungssituationen und Beratungsformen, die entweder von professionellen Beratenden oder einfach nur von betreuenden Mitarbeitenden in unserem Fall ausgeführt werden und zum Entstehen dieser Arbeit einen Beitrag leisten. Die Wichtigkeit eines Beratungsgesprächs liegt in der Klärung der Rahmenbestimmung. Diese Arbeit spricht spezifisch die sozialpädagogische Beratung der Menschen mit einer kognitiven Beeinträchtigung im stationären Setting, die sich verbal äussern können. Vielfach finden solche Beratungssituationen in offenen Settings und Überganssituationen statt, die Schwierigkeiten mit sich bringen, die sogenannten «zwischen Tür und Angel-Gespräche» und die sich spontan ergebenden Beratungssituationen von den strukturierten Beratungsverfahren in geschlossenen Settings, wo eine festgelegte Reihenfolge eingehalten wird. Genau diese geregelte Interaktion zwischen den Beratenden und den Ratsuchenden und die dazugehörigen festgelegten Handlungsschritte führen zur Fraglichkeit der Professionalisierung. Werden professionelle Beratende oder betreuende Mitarbeitenden in diesen Einrichtungen spontan aufgesucht und ihre Beratertätigkeit in Anspruch genommen, bleibt fraglich, ob es sich wirklich um eine professionelle sozialpädagogische Beratung handelt.
