description: We consider the free propagation of totally symmetric massive bosonic fields in nontrivial backgrounds. The mutual compatibility of the dynamical equations and constraints in flat space amounts to the existence of an Abelian algebra formed by the d'Alembertian, divergence and trace operators. The latter, along with the symmetrized gradient, symmetrized metric and spin operators, actually generate a bigger non-Abelian algebra, which we refer to as the "consistency" algebra. We argue that in nontrivial backgrounds, it is some deformed version of this algebra that governs the consistency of the system. This can be motivated, for example, from the theory of charged open strings in a background gauge field, where the Virasoro algebra ensures consistent propagation. For a gravitational background, we outline a systematic procedure of deforming the generators of the consistency algebra in order that their commutators close. We find that equal-radii AdSp X Sq manifolds, for arbitrary p and q, admit consistent propagation of massive and massless fields, with deformations that include no higher-derivative terms but are non-analytic in the curvature. We argue that analyticity of the deformations for a generic manifold may call for the inclusion of mixed-symmetry tensor fields like in String Theory.

Expressions of Medical Student Burnout on Reddit: An Autonetnographic Study of /r/medicalschool
Creators: name: Song, Ye Kyung
Publisher: name: Zenodo
Year: 2019

description: Medical student burnout is currently incredibly common. Recent studies report that approximately 50 percent of students had scores indicative of burnout on the Maslach Burnout Inventory. Burnout can become chronic, and up to 73.2% of the afflicted fail to recover while they are trainees. This is significant because burnout profoundly affects the inner world of the physician and places them at a higher risk of depression, substance use disorder, and suicide; in turn, burnout impacts their professional behaviors and the quality of patient care. This dissertation explores the hypothesis that negative emotions that arise from unresolved ethical, technical, behavioral, and existential discomforts and their role in mediating burnout; this includes the discomforts experienced due to the lack of decision-making power held during medical training. I utilize an autonetnographic approach to understand how medical students on /r/medicalschool, an online news-aggregating forum, conceptualize and operationalize the term “burnout,” how they cope with burnout, and what barriers and attitudes they face that perpetuate a system that fosters burnout. This autonetnography is a study of spaces and interactions on a freely accessible, anonymous public forum. Within these spaces and interactions, I explore how the social, economic, and political forces present within medical education shape the ethical affordances that medical students have. Based on these understandings, I challenge the notion that medical student burnout is due to unresolved existential discomforts – an inability to come to terms with patients’ death and suffering – but is rather due to the creation of an Existential void. Students feel lost as they question the purpose of their training because of the incongruency between the values and moral norms professed and those practiced in medicine, and they experience being objectified when reduced to quantifiable metrics, such as board scores and clinical evaluations. With this new insight and understanding into medical student burnout, I propose changes that address the root cause of student burnout – ontological insecurity caused by real-world micro- and macro-economic pressures.

A Pati-Salam Version of Subcritical Hybrid Inflation
Creators: name: Bryant, B. Charles
name: Raby, Stuart
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In this paper we present a model of subcritical hybrid inflation with a Pati-Salam [PS] symmetry group. Both the inflaton and waterfall fields contribute to the necessary e-foldings of inflation, while only the waterfall field spontaneously breaks PS hence monopoles produced during inflation are diluted during the inflationary epoch. The model is able to produce a tensor-to-scalar ratio, $r < 0.09$ consistent with the latest BICEP2/Keck and Planck data, as well as scalar density perturbations and spectral index, $n_s$, consistent with Planck data. For particular values of the parameters, we find $r = 0.084$ and $n_s = 0.0963$. The energy density during inflation is directly related to the PS breaking scale, $v_{PS}$. The model also incorporates a $\mathbb{Z}_4^R$ symmetry which can resolve the $μ$ problem and suppress dimension 5 operators for proton decay, leaving over an exact $R$-parity. Finally the model allows for a complete three family extension with a $D_4$ family symmetry which reproduces low energy precision electroweak and LHC data.

Analysing the Effects of Routing Centralization on BGP Convergence Time

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Software-defined networking (SDN) has improved the routing functionality in networks like data centers or WANs. Recently, several studies proposed to apply the SDN principles in the Internet's inter-domain routing as well. This could offer new routing opportunities and improve the performance of BGP, which can take minutes to converge to routing changes. Previous works have demonstrated that centralization can benefit the functionality of BGP, and improve its slow convergence that causes severe packet losses and performance degradation. However, due to (a) the fact that previous works mainly focus on system design aspects, and (b) the lack of real deployments, it is not clearly understood yet to what extent inter-domain SDN can improve performance. To this end, in this work, we make the first effort towards analytically studying the effects of routing centralization on the performance of inter-domain routing, and, in particular, the convergence time of BGP. Specifically, we propose a Markovian model for inter-domain networks, where a subset of nodes (domains) coordinate to centralize their inter-domain routing. We then derive analytic results that quantify the BGP convergence time under various network settings (like, SDN penetration, topology, BGP configuration, etc.). Our analysis and results facilitate the performance evaluation of inter-domain SDN networks, which have been studied (till now) only through simulations/emulations that are known to suffer from high time/resource requirements and limited scalability.

description: Nicht die Akademisierung ist das Problem des Ausbildungssystems, sondern die mangelnde Integration von Jugendlichen mit niedriger Schulbildung – das ist ein zentraler Befund unseres Monitor Ausbildungschancen 2023. 

Wie kommen wir zu dieser Einschätzung? Drei Ergebnisse: 

•             In den vergangenen zehn Jahren ist der Anteil derer, die mit Abitur eine duale oder schulische Ausbildung beginnen, deutlich gestiegen.

•             Schulabgänger:innen mit Hauptschulabschluss haben es dagegen immer schwerer, einen Ausbildungsplatz zu bekommen. Es sinkt nicht nur die Zahl der Hauptschulabsolvent:innen insgesamt, sondern auch der Anteil derjenigen, die in Ausbildung übergehen. 

•             Viele Jugendliche fallen ganz aus dem System: Die Zahl der Jugendlichen hat sich wieder deutlich erhöht, die sich weder in Ausbildung noch in der Schule oder in Arbeit befinden, die sogenannten NEETs (Not in Employment, Education or Training).

Im Monitor Ausbildungschancen 2023 wird der Frage nachgegangen, wie sich die Übergangschancen von jungen Menschen in die verschiedenen Bereiche des beruflichen Bildungssystems in Abhängigkeit der jeweiligen Schulabschlüsse entwickelt haben. Der Monitor enthält in der Neuauflage darüber hinaus ein Kapitel mit einer vergleichenden Analyse zur Situation in den 16 Bundesländern.

Natürlich beinhaltet der Monitor auch Handlungsempfehlungen: Die Bertelsmann Stiftung fordert seit Jahren die Einführung einer Ausbildungsgarantie. Denn wenn der (Ausbildungs-)Markt versagt, muss der Staat eingreifen, zumal es um nichts Geringeres geht als um die Bildungschancen junger Menschen und damit verbunden auch der Zukunft des Landes. Eine Ausbildungsgarantie ist hier das Mittel der Wahl – wenn sie eine echte Garantie für alle Jugendlichen darstellt, die bei der Ausbildungsstellensuche leer ausgegangen sind.

Der Monitor Ausbildungschancen wurde vom Forschungsinstitut für Bildungs- und Sozialökonomie (FiBS) unter Leitung von Dr. Dieter Dohmen im Auftrag der Bertelsmann Stiftung erstellt. Die 3., korrigierte Auflage ersetzt sowohl die erste Auflage (DOI 10.11586/2022149) als auch die 2., erweiterte Auflage (DOI 10.11586/2023012). Die zweite Auflage wurde um einen Ländervergleich, ein umfangreiches Glossar zur Erläuterung der verwendeten Fachbegriffe sowie nähere Informationen zur Methodik ergänzt. Die jetzt vorliegende 3. Auflage wurde zusätzlich um die Daten zur schulischen Ausbildung für die Jahre 2020 und 2021 in den Ländern Nordrhein-Westfalen, Niedersachsen und Sachsen-Anhalt um die „Bundesstatistik für Ausbildung in den Pflegeberufen“ ergänzt und die Gesamtauswertungen entsprechend korrigiert.

description: Tumour heterogeneity is thought to be a major barrier to successful cancer treatment due to the presence of drug resistant clonal lineages. However, identifying the characteristics of such lineages that underpin resistance to therapy has remained challenging. Here, we utilise clonal transcriptomics with WILD-seq; Wholistic Interrogation of Lineage Dynamics by sequencing, in mouse models of triple-negative breast cancer (TNBC) to understand response and resistance to therapy, including BET bromodomain inhibition and taxane-based chemotherapy. These analyses revealed oxidative stress protection by NRF2 as a major mechanism of taxane resistance and led to the discovery that our tumour models are collaterally sensitive to asparagine deprivation therapy using the clinical stage drug L-asparaginase after frontline treatment with docetaxel. In summary, clonal transcriptomics with WILD-seq identifies mechanisms of resistance to chemotherapy that are also operative in patients and pin points asparagine bioavailability as a druggable vulnerability of taxane-resistant lineages.

description: The WI network is composed of stations geographically distributed all along the Lesser Antilles subduction zone, from Grenada in the south, to St Barthélémy in the north.
The stations all share the following features: (1) very Small Aperture Terminal (VSAT) satellite telemetry, (2) solar power and 10-day battery, (3) multi sensor stations with broadband seismometer (Nanometrics - Trillium120s or 240s) , accelerometer (Kinemetrics - Episensors +/- 2G) and continuous GNSS (Trimble, NetR9), (4) vault and installation design to minimize environmental effects on the instruments.
The vault design addresses several needs: environmental insulation, ground coupling,and instrument security.
The seismic pier, which can accommodate a broadband seismometer, with its insulation, and an accelerometer, is mechanically isolated from the vault walls.
The sensors are separated from the electronics in order to avoid any electric, magnetic and thermal mutual influence.
The vault is further insulated with 6 cm thick Styrofoam panels covering every floor. A “CASSIS” shielding (CASserole SISmologique – seismic cooking pot) which is based on the granite slab and “cooking pot”, attenuates the barometric effects and then decreases the vertical noise level of broadband sensors by several dBs.
An additional mumetal cover on Trillium 240 damps magnetic field variations by 100 dB between 50s and 600s, which is the range of the strongest natural variations during magnetic storms.
Data of this network are fully disseminated in SEED format (Seismic data) or Rinex format (GNSS) in real time (raw data) and after a validation.
The B-ring's surface mass density from hidden density waves: Less than meets the eye?

description: Saturn's B ring is the most opaque ring in our solar system, but many of its fundamental parameters, including its total mass, are not well constrained. Spiral density waves generated by mean-motion resonances with Saturn's moons provide some of the best constraints on the rings' mass density, but detecting and quantifying such waves in the B ring has been challenging because of this ring's high opacity and abundant fine-scale structure. Using a wavelet-based analyses of 17 occultations of the star gamma Crucis observed by the Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft, we are able to examine five density waves in the B ring. Two of these waves are generated by the Janus 2:1 and Mimas 5:2 Inner Lindblad Resonances at 96,427 km and 101,311 km from Saturn's center, respectively. Both of these waves can be detected in individual occultation profiles, but the multi-profile wavelet analysis reveals unexpected variations in the pattern speed of the Janus 2:1 wave that might arise from the periodic changes in Janus' orbit. The other three wave signatures are associated with the Janus 3:2, Enceladus 3:1 and Pandora 3:2 Inner Lindblad Resonances at 115,959 km, 115,207 km and 108,546 km. These waves are not visible in individual profiles, but structures with the correct pattern speeds can be detected in appropriately phase-corrected average wavelets. Estimates of the ring's surface mass density derived from these five waves fall between 40 and 140 g/cm^2, even though the ring's optical depth in these regions ranges from 1.5 to almost 5. This suggests that the total mass of the B ring is most likely between one-third and two-thirds the mass of Saturn's moon Mimas.

description: Brownian dynamics simulations are an increasingly popular tool for understanding spatially-distributed biochemical reaction systems. Recent improvements in our understanding of the cellular environment show that volume exclusion effects are fundamental to reaction networks inside cells. These systems are frequently studied by incorporating inert hard spheres (crowders) into three-dimensional Brownian dynamics simulations, however these methods are extremely slow owing to the sheer number of possible collisions between particles. Here we propose a rigorous "crowder-free" method to dramatically increase simulation speed for crowded biochemical reaction systems by eliminating the need to explicitly simulate the crowders. We consider both the case where the reactive particles are point particles, and where they themselves occupy a volume. We use simulations of simple chemical reaction networks to confirm that our simplification is just as accurate as the original algorithm, and that it corresponds to a large speed increase.

description: Die Fallstudie geht im Sinn der Aktionsforschung der Frage nach, wie das Rollenspiel in Kombination mit der Methode der kritischen Exploration (vgl. Meyer, 2019) das arithmetische Denken von zwei Kindern mit Rechenschwierigkeiten positiv beeinflussen kann.
 Die Pädagogin spielte während sechs Treffen einen sprechenden und empathischen Taschenrechner, der bei Unklarheiten nachfragt, arithmetisch modelliert und positiv provoziert. Die Analyse der Daten aus den Tests, dem Forschungstagebuch und den Videotranskriptionen zeigte, dass die Wechselwirkungen im arithmetischen Operieren bei allen Akteuren verändert wurden. Bei den zwei ausgewählten Kindern konnte eine Entspannung für das Fach Mathematik und eine Freude am eigenen Denken erreicht werden. Für die rollenspielende Lehrperson bedeutet die Anwendung dieses Handlungsmodells eine Befreiung aus althergebrachten Denkmustern. Die gewandelte Grundhaltung verändert die Förderplanung und -arbeit grundlegend.
 Künftige Forschungen müssten die Metakognition in die Dialoge integrieren und die Methode in Gruppensettings erproben.

description: We report achieving enhanced nuclear magnetization in a magnetic resonance force microscope experiment at 0.6 tesla and 4.2 kelvin using the dynamic nuclear polarization (DNP) effect. In our experiments a microwire coplanar waveguide delivered radiowaves to excite nuclear spins and microwaves to excite electron spins in a 250 nm thick nitroxide-doped polystyrene sample. Both electron and proton spin resonance were observed as a change in the mechanical resonance frequency of a nearby cantilever having a micron-scale nickel tip. NMR signal, not observable from Curie-law magnetization at 0.6 tesla, became observable when microwave irradiation was applied to saturate the electron spins. The resulting NMR signal's size, buildup time, dependence on microwave power, and dependence on irradiation frequency was consistent with a transfer of magnetization from electron spins to nuclear spins. Due to the presence of an inhomogenous magnetic field introduced by the cantilever's magnetic tip, the electron spins in the sample were saturated in a microwave-resonant slice 10's of nm thick. The spatial distribution of the nuclear polarization enhancement factor $ε$ was mapped by varying the frequency of the applied radiowaves. The observed enhancement factor was zero for spins in the center of the resonant slice, was $ε= +10$ to $+20$ for spins proximal to the magnet, and was $ε= -10$ to $-20$ for spins distal to the magnet. We show that this bipolar nuclear magnetization profile is consistent with cross-effect DNP in a $\sim \! 10^{5} \: \mathrm{T} \: \mathrm{m}^{-1}$ magnetic field gradient. Potential challenges associated with generating and using DNP-enhanced nuclear magnetization in a nanometer-resolution magnetic resonance imaging experiment are elucidated and discussed.

description: Несмотря на наметившуюся в последнее время положительную тенденцию сокращения нефтегазовых доходов в федеральном бюджете РФ, их доля продолжает оставаться значительной. На мировом энергетическом рынке происходят значительные изменения: США, добиваясь вытеснения России из европейского газового рынка, вместе с Евросоюзом объявили тотальную
экономическую войну, ЕС объявил эмбарго на российский газ. Поставки газа в страны Евросоюза
прекратились в связи с диверсией на газопроводах, отказом Украины принимать газ через станции
Луганской народной республики, вошедшей в состав России. С целью остановки роста цен на энергоносители в связи с непрекращающимся спросом на них ЕС и США предпринимают попытки
по установлению потолка цен на российский газ и нефть. В настоящее время Евросоюз установил
потолок цен на российскую нефть в сумме 60 долл. за баррель. Цель исследования – проанализировать динамику изменения нефтегазовых доходов федерального бюджета за период с 2010 года
по настоящее время и как повлияла на это складывающаяся ситуация на мировом энергетическом
рынке. В статье расмотрены доходы бюджета в зависимости от двух факторов: цены и количества.
Установлено, что в настоящее время при снижении количества поставок энергоносителей доходы
бюджета растут из-за скачка цен, вызванного санкциями Запада.
description: Despite the recent upward trend in decreasing oil and gas revenues in the federal budget,
their share remains significant. The global energy market faces dramatic changes, with the United States of
America and the European Union declaring a total economic war on Russia in order to reduce Russia’s influence on the European gas market, as well as the European Union announcing an embargo on Russian gas.
Gas deliveries to European Union countries were halted due to sabotage on gas pipelines and Ukraine’s refusal to receive gas through the stations of the Luhansk People’s Republic, which became part of Russia.
The European Union and the United States of America are attempting to set a price ceiling for Russian gas
and oil in order to stop the rise in energy prices caused by ongoing demand for them. At the current moment,
the European Union has set a price ceiling for Russian oil at $60 per barrel. The aim of the study is to examine the dynamics of changes in oil and gas revenues in the federal budget since 2010, as well as the impact of
the current global energy market situation. The article analyzes types of the budget revenues based on price and quantity. According to the study, despite a decrease in energy supplies, budget revenues are increasing
due to a price increase caused by Western sanctions.

description: We study spin-orbit torques and charge pumping in magnetic quasi-one dimensional zigzag nanoribbons with hexagonal lattice, in the presence of large intrinsic spin-orbit coupling. Such a system experiences topological phase transition from a trivial band insulator to a quantum spin Hall insulator either by tuning the magnetization direction or the intrinsic spin-orbit coupling. We find that spin-charge conversion efficiency (i.e. spin-orbit torque and charge pumping) is dramatically enhanced at the topological transition, displaying a substantial angular anisotropy.

description: Motivated by a recent paper by Rychkov-Tan \cite{Rychkov:2015naa}, we calculate the anomalous dimensions of the composite operators at the leading order in various models including a $ϕ^3$-theory in $(6-ε)$ dimensions. The method presented here relies only on the classical equation of motion and the conformal symmetry. In case that only the leading expressions of the critical exponents are of interest, it is sufficient to reduce the multiplet recombination discussed in \cite{Rychkov:2015naa} to the classical equation of motion. We claim that in many cases the use of the classical equations of motion and the CFT constraint on two- and three-point functions completely determine the leading behavior of the anomalous dimensions at the Wilson-Fisher fixed point without any input of the Feynman diagrammatic calculation. The method developed here is closely related to the one presented in \cite{Rychkov:2015naa} but based on a more perturbative point of view.

description: The anisotropic two-dimensional (2D) van der Waals (vdW) layered materials, with both scientific interest and potential application, have one more dimension to tune the properties than the isotropic 2D materials. The interlayer vdW coupling determines the properties of 2D multi-layer materials by varying stacking orders. As an important representative anisotropic 2D materials, multilayer rhenium disulfide (ReS2) was expected to be random stacking and lack of interlayer coupling. Here, we demonstrate two stable stacking orders (aa and a-b) of N layer (NL, N>1) ReS2 from ultralow-frequency and high-frequency Raman spectroscopy, photoluminescence spectroscopy and first-principles density functional theory calculation. Two interlayer shear modes are observed in aa-stacked NL-ReS2 while only one interlayer shear mode appears in a-b-stacked NL-ReS2, suggesting anisotropic-like and isotropic-like stacking orders in aa- and a-b-stacked NL-ReS2, respectively. The frequency of the interlayer shear and breathing modes reveals unexpected strong interlayer coupling in aa- and a-b-NL-ReS2, the force constants of which are 55-90% to those of multilayer MoS2. The observation of strong interlayer coupling and polytypism in multi-layer ReS2 stimulate future studies on the structure, electronic and optical properties of other 2D anisotropic materials.

description: The influence of particle size and a surface modifier on the self-assembly of the nonionic surfactant C12E5 at silica nanoparticles was studied by adsorption measurements and small-angle neutron scattering (SANS). Silica nanoparticles of diameter 13 to 43 nm were synthesized involving the basic amino acid lysine. A strong decrease of the limiting adsorption of C12E5 with decreasing particle diameter was found. To unveil the role of lysine as a surface modifier for the observed size dependence of surfactant adsorption, the morphology of the surfactant aggregates assembled on pure siliceous nanoparticles (Ludox-TMA, 27 nm) and their evolution with increasing lysine concentration at a fixed surfactant-to-silica ratio was studied by SANS. In the absence of lysine, the surfactant forms surface micelles at silica particles. As the concentration of lysine is increased, a gradual transition from the surface micelles to detached wormlike micelles in the bulk solution is observed. The changes in surfactant aggregate morphology cause pronounced changes of the system properties, as is demonstrated by turbidity measurements as a function of temperature. These findings are discussed in terms of particle surface curvature and surfactant binding strength, which present new insight into the delicate balance between the two properties.

description: Cooling and trapping of atoms by light has enabled one to build and manipulate quantum systems at the single atom level. Such a bottom-up approach becomes one of the fascinating challenges toward scalable and highly controllable quantum systems, e.g., a large-scale quantum information machine. Their implementation requires crucial pre-requisites: scalablity, site distinguishability, and reliable single-atom loading into sites. The widely adopted methods satisfies the two former conditions relatively well, but the last condition, filling single atoms onto individual sites, relies mostly on the probabilistic loading, implying that loading a pre-defined set of atoms in given positions will be hampered exponentially. Two approaches are readily thinkable to overcome this issue: increasing the single-atom loading efficiency and relocating abundant atoms into unfilled positions. Realizing the relocation is directly related to how many atoms can be transportable in a designer way. Here, we demonstrate a dynamic holographic single-atom tweezers with unprecedented degrees of freedom of 2N. In a proof-of-principle experiment conducted with cold rubidium atoms, simultaneous rearrangements of N=9 single atoms are successfully performed. This method may be further applicable to deterministic N single-atom loading, coherent transport, and controlled collisions.

description: National, but also regional and local media intensively covered the numerous arrivals of asylum-seeking migrants in Germany in 2015 and 2016. The focus of media reporting changed over time, reflecting the general social negotiation process around the reception of refugees and the challenges for the larger society. While those media discourses, their temporal dimensions and changing foci have already been intensively analysed on the national level, research on the local representation of the topic are missing so far. This working paper uses a regional comparative setting in order to identify similarities and differences in the representation of refugees by local media. The main aim of this endeavor is to understand differences in local and regional discourses on refugee reception. The study is embedded in the research project "Future for Refugees in Rural Regions in Germany", where the author is responsible for the work package “Role of Civil Society and Attitudes of the Host Society”.

On the fundamental aspect of the first Kelvin's relation in thermoelectricity

description: Kelvin's relations may be considered as cornerstones in the theory of thermoelectricity. Indeed, they gather together the three thermoelectric effects, associated respectively with Seebeck, Peltier and Thomson, to get a unique and consistent description of thermoelectric phenomena. However, their physical status in literature are quite different. On the one hand, the second Kelvin's relation is associated with the microscopic reversibility, considered as a fundamental thermodynamical property. On the other hand, the first Kelvin's relation is traditionally introduced only as a convenient mathematical relation between Seebeck and Thomson coefficients. In the present article, we stress that, contrary to common believes, this relation may demonstrates deeper insights than a bold mathematical expression between thermoelectric coefficients. It actually reflects the coexistence of two different mechanisms taking place inside thermoelectric systems: Energy conversion and reorganization of heat flow when Seebeck coefficient varies.

description: We present an analysis of the relative throughputs of the 3.9-metre Anglo-Australian Telescope's 2dF/HERMES system, based upon spectra acquired during the first two years of the GALAH survey. Averaged spectral fluxes of stars were compared to their photometry to determine the relative throughputs of fibres for a range of fibre position and atmospheric conditions. We find that overall the throughputs of the 771 usable fibres have been stable over the first two years of its operation. About 2.5 per cent of fibres have throughputs much lower than the average. There are also a number of yet unexplained variations between the HERMES bandpasses, and mechanically & optically linked fibre groups known as retractors or slitlets related to regions of the focal plane. These findings do not impact the science that HERMES will produce.

description: We provide estimates of the wave energy reaching the solar chromosphere and corona in a network-like magnetic field topology, including a coronal null point. The waves are excited by an instantaneous strong subphotospheric source and propagate through the subphotosphere, photosphere, chromosphere, transition region, and corona with the plasma beta and other atmospheric parameters varying by several orders of magnitude. We compare two regimes of the wave propagation: a linear and nonlinear regime. While the amount of energy reaching the corona is similar in both regimes, this energy is transmitted at different frequencies. In both cases the dominant periods of waves at each height strongly depend on the local magnetic field topology, but this distribution is only in accordance with observations in the nonlinear case.

description: Das Frühförderprogramm „PAT – Mit Eltern Lernen“ ist Bestandteil der Studie „ZEPPELIN 0-3“. Im PAT-Programm begleiten PAT – Elterntrainerinnen Familien mit Kindern von 0-3 Jahren in Risikokonstellationen zu Hause und in Begegnungszentren. Ziel ist, die Erziehungskompetenz der Eltern zum Wohl des Kindes und der ganzen Familie zu stärken. Diese empirische Forschungsarbeit überprüft und bewertet mit der „Beobachtungsskala für Hausbesuche“ (BSHBA+) die Kompetenz der Elterntrainerinnen während Hausbesuchen im dritten Programmjahr. Die Ergebnisse dieser zweiten Überprüfung bestätigen, dass die Hausbesucherinnen insgesamt qualitativ gute bis sehr gute Arbeit leisten und die Eltern kompetent begleiten. Eine differenzierte Analyse zeigt, dass die Kooperation zwischen Elterntrainerinnen und Eltern bezüglich der inhaltlichen Planung und Mitgestaltung der Hausbesuche Optimierungsbedarf aufweist.
