description: We study the evolution of photoluminescence (PL) from homogeneous and inhomogeneous ensembles of a few coupled QDs. We discuss the relation between signals from a given QD ensemble under strong and weak excitation (full inversion and linear response regimes): A system homogeneous enough to manifest superradiant emission when strongly inverted shows a non-exponential decay of the PL signal under spatially coherent weak excitation. In an inhomogeneous ensemble the PL decay is always nearly exponential with a qualitatively different form of the time dependence in the two excitation regimes and with a higher rate under weak excitation.

description: Die Coronavirus-Pandemie hat zu einer Preissteigerung für Waren mit hoher Nachfrage geführt. Übermäßige Preissteigerung wirkt negativ auf die Verbraucher, besonders in einer so schweren Zeit wie Pandemie. Im Laufe von vielen Jahren haben die zuständigen Behörden Ermittlungen zu angeblichen „Fällen der Preisüberhöhung“ eingeleitet. Während der Pandemie hat jedoch die Zahl der Fälle der Preisüberhöhung, insbesondere in Bezug auf die Waren mit hoher Nachfrage wie pharmazeutische Produkte, Handreiniger, Desinfektionsmittel und Masken. Einige sprechen sich jedoch gegen Preiskontrollen aus, da dies als Schädigung eines offenen Wettbewerbsmarktes gedeutet wird. So ist die übermäßige Preissetzung zu einem Schlachtfeld im politischen und rechtlichen Raum geworden und hat kürzlich eine Unterstützung von Gerichten bekommen. Der Wettbewerb ist dafür bekannt, die Innovationen und Technologien zu stimulieren, die eine gesunde Wirtschaft schaffen, zu qualitativ hochwertigen Produkten führen und die Preise herabsetzen. Die Wissenschaftler treten der Preisregulierung als Hindernis für Wirtschaftswachstum und Innovationen entgegen. Während andere behaupten, dass die Preisregulierung das willkürliche Verhalten der Organisationen beseitigen soll, insbesondere von denen, die eine dominierende Position einnehmen. Außerdem wird es befürchtet, dass die Gerichte die Fälle in Bezug auf “überhöhte Preisbildung“ prüfen werden, da es schwierig ist zu bestimmen, ob der Preis “vernünftig oder übermäßig“ ist, da jedes Produkt und jede Dienstleistung in Bezug auf Kreativität, Produktion, Innovation und Kosten einzigartig ist. Demzufolge kann ein Eingriff der Gerichte dem Geschäft Schaden anrichten und letztlich den Verbraucher schädigen. Die Die Debatte über die Rechtspraxis in Bezug auf überhöhte Preise in der EU und in Kasachstan, die Feststellung überhöhter Preise, die Bestimmung, ob ein erhobener Preis übermäßig oder vernünftig ist, und die Diskussionen über die Folgen der Anerkennung eines Preises als übermäßig oder vernünftig, werden zwischen Wissenschaftlern und Gerichten fortgesetzt.

From Valhalla to Heaven: Norse Pagan Contact with Christianity in Anglo-Scandinavian England

description: In c. 962 King Edgar ‘The Peaceful’ granted a degree of cultural autonomy to the Scandinavian people of the north of England during an outbreak of plague. This thesis re-examines the religious conversion of the Scandinavians in the north of England in the context of the 962 plague, as well as in the ninth and tenth centuries to test assumptions of conversion and its mechanism. In doing so, I argue that the conversion of the Scandinavian people in the north of England during the ninth, and tenth centuries, was an ongoing and complex process encompassing changes in custom, worldview, and identity. This thesis contributes to recent scholarship in the field of Anglo-Scandinavian religious studies that has begun to challenge a longstanding assumption that shortly after their arrival in 865 the Scandinavian people rapidly gave up their religion for Christianity. In congruence with this recent scholarship, I consider two Norse terms that refer to religion, siðr (custom) and trú (faith) that are deployed by Christian authorities in order to investigate how this example of religious conversion may have occurred. In this thesis I read Edgar’s laws for potential insights into the continuation of ‘heathenism’ and argue that the outbreak of plague in 962 can possibly be read as a moment of religious ‘reversion’, whereby the laity of the north of England engaged in non-Christian practices to avoid health crises. Additionally, I read the laws of Æthelred II for the prohibition of paganism, and homiletic material from Ælfric and Wulfstan II for their attempts to eliminate and/or Christianise ‘pagan’ healing practices as well as to build cultural consensus. A close reading of Christian legal and literary material through the lens of hybridisation theory reveals that the conversion of Scandinavians in the north of England was an ongoing and complex process.

description: Phase contrast imaging seeks to reconstruct the complex refractive index of an unknown sample from scattering intensities, measured for example under illumination with coherent X-rays. By incorporating refraction, this method yields improved contrast compared to purely absorption-based radiography but involves a phase retrieval problem which, in general, allows for ambiguous reconstructions. In this paper, we show uniqueness of propagation-based phase contrast imaging for compactly supported objects in the near field regime, based on a description by the projection- and paraxial approximations. In this setting, propagation is governed by the Fresnel propagator and the unscattered part of the illumination function provides a known reference wave at the detector which facilitates phase reconstruction. The uniqueness theorem is derived using the theory of entire functions. Unlike previous results based on exact solution formulae, it is valid for arbitrary complex objects and requires intensity measurements only at a single detector distance and illumination wave length. We also deduce a uniqueness criterion for phase contrast tomography, which may be applied to resolve the three-dimensional structure of micro- and nano-scale samples. Moreover, our results may have some significance to electronic imaging methods due to the equivalence of paraxial wave propagation and Schrödinger's equation.
Youth Political Engagement in Australia and the United States: Student Councils and Volunteer Organizations as Communities of Practice
Creators: name: Homana, Gary A.
Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: Lave and Wenger’s Communities of Practice is presented as a conceptual framework for examining extracurricular activities as a part of democratic schools’ contribution to students’ civic engagement. Data from the IEA Civic Education Study is analyzed to investigate research questions on the association between participation in two civic communities of practice (student council and volunteer organizations) and two types of expected adult political participation as well as trust in political institutions in Australia and the United States. Method/Approach: The methodology examined data from students in nationally representative samples of schools that surveyed 14-year-olds in 1999. This was the most recent large scale study of civic education in which these two countries participated. Analysis of variance examined main effects and statistical interactions, especially by gender. Findings: Findings were that in both countries, participation in the two civic communities of practice was associated with higher levels of trust in political institutions and greater expectations to become an informed voter and an active citizen. The results also suggest that male and female students in the United States experience these communities of practice in different ways. Practical advantages to encouraging democratic communities of practice are important to the experience of democracy at school.

Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: This article explores different strands of educational discourse about sexual diversity in Portuguese schools, from the students’ perspectives. Method: The methodological approach consisted in conducting focus groups discussions: 36 with 232 young students (H = 106, M = 126) in 12 public secondary schools. Findings: Students reveal a polyphony of discourses that gravitate between liberal acceptance, conditional acceptance and intolerance. Research implications: Attention is drawn not only to discriminatory processes that question school as a democratic place for LGBT youth, but also to the gap between what is legally decreed and a lack of know-how in the approach to sexual diversity in school.

Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: The paper explores what emotions do in social science education through two specific cases and discusses the relation between emotion and politicization in the subject education. Method/Approach: The cases are selected from an on-going dissertation project that uses interviews, video and observations in examining how social science education is played out in practice, with a focus on the students. Inspired by Sara Ahmed, emotion is seen as relational. Findings: Seeing emotions as relational makes it possible to capture a dynamic in the classroom that brings a complexity to a discussion on social science education. There is a relation between emotion and politicization; in the two cases, emotion signals that a subject matter or situation is contested.

description: Quantum computing is in an era of limited resources. Current hardware lacks high fidelity gates, long coherence times, and the number of computational units required to perform meaningful computation. Contemporary quantum devices typically use a binary system, where each qubit exists in a superposition of the $\ket{0}$ and $\ket{1}$ states. However, it is often possible to access the $\ket{2}$ or even $\ket{3}$ states in the same physical unit by manipulating the system in different ways. In this work, we consider automatically encoding two qubits into one four-state qu\emph{quart} via a \emph{compression scheme}. We use quantum optimal control to design efficient proof-of-concept gates that fully replicate standard qubit computation on these encoded qubits. We extend qubit compilation schemes to efficiently route qubits on an arbitrary mixed-radix system consisting of both qubits and ququarts, reducing communication and minimizing excess circuit execution time introduced by longer-duration ququart gates. In conjunction with these compilation strategies, we introduce several methods to find beneficial compressions, reducing circuit error due to computation and communication by up to 50\%. These methods can increase the computational space available on a limited near-term machine by up to 2x while maintaining circuit fidelity.

title: Energiewende in der Raumplanung
Creators: name: Dunger, Amadeus
Year: 2022

description: Das Ziel der vorliegenden Masterarbeit ist es, den Zusammenhang zwischen der Energiewende und der Raumplanung am Beispiel von PV-Freiflächenanlagen in der Planungsregion Chemnitz zu untersuchen. Hierfür wird ein Mixed-Method-Ansatz gewählt, um die folgende Forschungsfrage zu beantworten: Wie ist der aktuelle Umgang hinsichtlich des Ausbaus von Photovoltaik- Freiflächenanlagen in der Region Chemnitz auf regionalplanerischer Ebene zu bewerten? Im ersten Schritt der Bearbeitung dieser Forschungsfrage werden alle relevanten Dokumente der verschiedenen Planungsebenen sowie relevante Gesetzestexte, die konkrete Aussagen zum Ausbau von PV-Freiflächenanlagen beinhalten, zusammengetragen. Dabei wird deutlich, dass insbesondere auf regionaler Ebene planerische Rahmenbedingungen für den Ausbau von PV-Freiflächenanlagen gesetzt werden, die durch VertreterInnen der kommunalen Ebene ausgestaltet werden. Hinzu kommen Gesetzestexte wie das EEG 2021, welches einen entscheidenden Einfluss auf den Aus-bau von PV-Freiflächenanlagen in der Region Chemnitz hat. Anschließend erfolgt eine GIS-basierte Potenzialflächenanalyse, die auf Basis eines eigens erstellten Kriterienkatalogs alle Potenzialgebiete und Gebiete, die eine Einzelfallprüfung erfordern, identifiziert. Diese potenziellen Gebiete für die Errichtung von PV-Freiflächenanlagen werden anschließend kartographisch dargestellt. Aus der Analyse der, im letzten Schritt geführten, ExpertInneninterviews mit exemplarisch gewählten VertreterInnen der kommunalen Ebene geht hervor, dass ein wachsendes Interesse am Ausbau von PV-Freiflächenanlagen innerhalb der Planungsregion Chemnitz zu verzeichnen ist. In diesem Zusammenhang wird ebenfalls deutlich, dass die InterviewpartnerInnen PV-Freiflächenanlagen als einen von vielen wichtigen Bau-steinen zur raumverträglichen und nachhaltigen Gestaltung der Energiewende in der Region betrachten. Zudem zeigen die ExpertInneninterviews, dass weitere Anpassungsmaßnahmen seitens des Gesetzgebers notwendig sind, um künftig zusätzliche Anreize für den Ausbau von PV-Freiflächenanlagen zu schaffen.
description: The present study seeks to systematically assess the implementation of the energy transition within the planning region of Chemnitz using the example of solar parks. Therefore, a mixed method approach is applied. As a first step, it provides a range of relevant planning documents and legislative texts that contain regulations regarding the construction of solar parks. Secondly, a GIS-based analysis identifies the potential areas that fit the predetermined criteria. The analysis of guideline-based interviews with representatives of a city administration and the renewable energy sector sets the focus on the local level. Thereby, the central objective is to evaluate the significance of solar parks within the energy transition on the communal level in the planning region of Chemnitz.

description: We compute the spin-dependent and spin-independent structure functions of the forward virtual-photon Compton tensor of the proton at one loop using heavy baryon effective theory including the Delta particle. We compare with previous results when existing. Using these results we obtain the leading hadronic contributions, associated to the pion and Delta particles, to the Wilson coefficients of the lepton-proton four fermion operators in NRQED. The spin-independent coefficient yields a pure prediction for the two-photon exchange contribution to the muonic hydrogen Lamb shift, $ΔE_{\rm TPE}(π\&Δ)=34(13)$ $μ$eV. We also compute the charge, $\langle r^n \rangle$, and Zemach, $\langle r^n \rangle_{(2)}$, moments for $n \geq 3$. Finally, we discuss the spin-dependent case, for which we compute the difference between the four-fermion Wilson coefficients relevant for hydrogen and muonic hydrogen.

Different Expectations in Civic Education: A Comparison of Upper-Secondary School Textbooks in Sweden
Creators: name: Arensmeier, Cecilia
Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: The aim of the article is to examine civic education in Sweden with regard to equality, by comparing curricula and textbooks for social studies in different tracks in upper-secondary school. Method: The study is based on qualitative text analysis, with quantitative features. The analysis maps themes cover-ed, the extent and depth of thematic coverage, and amount of emphasis on conceptual understanding and analytical training. Findings: The results point to some similarities between the tracks; limited attention is given to democratic values and civic engagement, apart from voting. Clear differences are found in amount of information and complexity. The most basic textbooks target the vocational track, while (some of) the textbooks for the academic track have an elaborated focus on complex conceptual understanding and analytical training. Practical implications: The findings indicate different expectations in civic education. Vocational students receive more limited opportunities to develop civic abilities, which might negatively affect the exercise of citizenship and increase political inequality.

description: One of the exact solutions of f(R) theories of gravity in the presence of different forms of matter exactly mimics the LCDM solution of general relativity at the background level. In this work we study the evolution of scalar cosmological perturbations in the covariant and gauge-invariant formalism and show that although the background in such a model is indistinguishable from the standard LCDM cosmology, this degeneracy is broken at the level of first-order perturbations. This is done by predicting different rates of structure formation in LCDM and the f(R) model both in the complete and quasi\hs static regimes.

European Identity and Citizenship in Estonia: Analyses of Textbooks and Theoretical Developments
Creators: name: Haav, Kaarel
Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: This article aims at elaboration of a relevant framework for European identity and citizenship. On this basis, comparative studies like ICSS, Estonian curricula, civic syllabuses and textbooks will be critically reviewed. Methods: The framework relies on former studies on democracy and education. The work also draws on normative materials for European citizenship, comparative empirical and critical studies. The conceptual system relies on the literature on basic sociological and semiotic concepts. This framework is used for analyses of the Estonian civic education system. Findings: The most general concepts like individual, society, culture, social actors and structures are defined as mutually inclusive. This has enabled to address complex and controversial social issues and achieve the aims of European identity and active citizenship. The Estonian curricula, civic syllabuses and textbooks herald democratic ideals, but fail to provide for them relevant concepts. They focus on empirical and normative descriptions of main political institutions. The books hardly describe how could active citizens evaluate and influence these institutions. Their content avoids complex and controversial issues like hierarchical power relations and social inequality and fails to describe both the hierarchical public administration and the system for public participation in Estonia. All this rather hinders students’ political literacy, critical thinking and active participation.

Detection of hot, metal-enriched outflowing gas around $z\approx\,$2.3 star-forming galaxies in the Keck Baryonic Structure Survey

description: We use quasar absorption lines to study the physical conditions in the circumgalactic medium of redshift $z\approx 2.3$ star-forming galaxies taken from the Keck Baryonic Structure Survey (KBSS). In Turner et al. 2014 we used the pixel optical depth technique to show that absorption by HI and the metal ions OVI, NV, CIV, CIII and SiIV is strongly enhanced within $|Δv|\lesssim170$ km/s and projected distances $|d|\lesssim180$ proper kpc from sightlines to the background quasars. Here we demonstrate that the OVI absorption is also strongly enhanced at fixed HI, CIV, and SiIV optical depths, and that this enhancement extends out to $\sim350$ km/s. At fixed HI the increase in the median OVI optical depth near galaxies is 0.3-0.7 dex and is detected at 2--3-$σ$ confidence for all seven HI bins that have $\log_{10}τ_{\rm HI}\ge-1.5$. We use ionization models to show that the observed strength of OVI as a function of HI is consistent with enriched, photoionized gas for pixels with $τ_{\rm HI}\gtrsim10$. However, for pixels with $τ_{\rm HI} \lesssim 1$ this would lead to implausibly high metallicities at low densities if the gas were photoionized by the background radiation. This indicates that the galaxies are surrounded by gas that is sufficiently hot to be collisionally ionized ($T > 10^5\,$K) and that a substantial fraction of the hot gas has a metallicity $\gtrsim 10^{-1}$ of solar. Given the high metallicity and large velocity extent (out to $\sim1.5\times v_{\rm circ}$) of this gas, we conclude that we have detected hot, metal enriched outflows arising from star-forming galaxies.

Intrusion Detection System and Corrective Actions in Modern Power Systems
Creators: name: Khan, Ahmad Mir Dad
Publisher: name: University of Illinois at Chicago
Year: 2023

description: The futuristic energy paradigm implicates high penetration of renewable based generation through embracing distributed energy generators (DEGs). At the grid edge, grid-feeding inverters are the prevailing type of DEGs. In this mode of operation, the DEGs are following the inertial response of the network and their capabilities is confined in injecting/absorbing current into/from their local point of common coupling bus. Henceforth, real-time system level coordination is crucial to assure the optimal utilization of DEGs that are potentially installed behind the meters. Thereby, concepts such as the power electronics-dominated grid (PEDG) with multi-layer control layout are used as an effective solution enabling DEGs efficient utilization. However, this futuristic power grid is anticipated to be vulnerable to malicious cyberattacks due to the dispersed generation nature. In this dissertation, an intrusion detection system (IDS) is developed to prevent malicious set-points assigned to the primary control layer by an intruder breaching into the secondary control layer. This IDS is based on a derived operation region identification framework. Precisely, each point of common coupling bus is described with a non-linear multi-dimensional manifold where the network DEGs set-points are appearing as the domain variables constructing the feasible voltage co-domain. The IDS is equipped at the primary control layer of each DEG, once an anomalous point of common coupling voltage is detected, the IDS authenticates the set-point with the developed operation regions to decide if an intrusion occurred or not. Then, after the intrusion is detected the IDS perform a corrective action to regain normal operation. This corrective action is based on consensus dynamics control that assures the normal operation of the PEDG in post-attack operation. Additionally, in this dissertation, a single-loop direct decoupled active and reactive power control without phase-locked-loop (PLL) requirement for grid-following inverters with adaptation to frequency deviations is developed. This developed control is proven to be asymptotically exponentially stable with Lyapunov theory. This proposed control is used as the main primary control for the network DEGs to avoid instabilities correlated with PLL synchronization usage.
Citizenship Education in Italian Textbooks. How Much Space is There for Europe and Active Citizenship?

Year: 2018

description: Purpose: In this article we investigated how the Italian school curricula incorporated European and national recommendations concerning European and Citizenship education, analysing how much and which kind of space is devoted to Europe and active citizenship in Italian high school textbooks. Design/methodology/approach: We selected a sample of bestseller textbooks of different disciplines (History and English as a Second Language) for secondary (lyceum and technical) school students (18 years old), including books explicitly designed for citizenship education, and analysed them using a mixed methods approach (quantitative analysis, and thematic content analysis). Findings: We argue that the current European recommendations on citizenship education are far from being incorporated in the architecture and the contents of textbooks used in Italian secondary schools. We identified some shortcomings which should be addressed to increase the capacity of textbooks to form young European citizen. Practical implications: The opportunities that the EU offers to young people to practice active citizenship and supporting the acquisition of critical and reflective skills beyond formal knowledge deserve more attention.

Discovering an active subspace in a single-diode solar cell model

description: Predictions from science and engineering models depend on the values of the model's input parameters. As the number of parameters increases, algorithmic parameter studies like optimization or uncertainty quantification require many more model evaluations. One way to combat this curse of dimensionality is to seek an alternative parameterization with fewer variables that produces comparable predictions. The active subspace is a low-dimensional linear subspace defined by important directions in the model's input space; input perturbations along these directions change the model's prediction more, on average, than perturbations orthogonal to the important directions. We describe a method for checking if a model admits an exploitable active subspace, and we apply this method to a single-diode solar cell model with five input parameters. We find that the maximum power of the solar cell has a dominant one-dimensional active subspace, which enables us to perform thorough parameter studies in one dimension instead of five.

It has been suggested that such particles may be described as compact four-quark states or loosely bound meson molecules. In the present work we analyze the Z_c(') -> eta_c rho decay using both approaches. Such channel might provide useful insights on the nature of the Z_c('), helping discriminating between the two different models.

title: In Österreich eingesetzte monoklonale Antikörper
Creators: name: Salem, Esra
Year: 2022

description: Seit nahezu 20 Jahren sind monoklonale Antikörper in unserem Arzneischatz zu finden. Seitdem sind 67 monoklonale Antikörper in 11 Indikationsgebieten in Österreich zugelassen. Bemerkenswert ist, dass viele bisher als unbehandelbar geltende Erkrankungen durch diese neuen Wirkstoffe für eine Therapie zugänglich geworden sind, darunter auch viele seltene Erkrankungen. Aber auch bei Erkrankungen, gegen die bereits zahlreiche Wirkstoffe im Einsatz sind, wurden durch die Verwendung monoklonale Antikörper wesentliche Fortschritte erzielt, da häufig eine kausale Therapie erst durch diese Wirkstoffe möglich geworden ist. Der heutige Kenntnisstand über die Wirkmechanismen von monoklonalen Antikörper erlaubt tiefe Einblicke in die Regulationsmechanismen des menschlichen Körpers und über die Kommunikation der verschiedenen Zellen untereinander, sowohl im physiologischen als auch im pathologischen Stoffwechselgeschehen. Ziel der Masterarbeit war es alle monoklonalen Antikörper, die von 2004-2022 zugelassen wurden zu erfassen und nach Indikationsgebieten geordnet zu vergleichen. Die für ein Indikationsgebiet pharmazeutisch relevanten Targets der Wirkstoffe wurden genauso beleuchtet wie die zum Teil sehr komplizierten Wirkmechanismen und die daraus resultierbaren arzneilichen Anwendungsgebiete. Ein umfangreiches Literaturverzeichnis mit großenteils elektronisch abrufbaren Quellen erleichtert das tiefergehende Studium dieser komplexen Materie.
description: Monoclonal antibodies have been part of our medicinal treasury for almost 20 years. Since then, 67 monoclonal antibodies have been approved in 11 indication areas in Austria. It is noteworthy that many diseases that were previously considered untreatable, including many rare diseases, have become accessible for therapy thanks to these new active ingredients. Significant progress has been made using monoclonal antibodies, since causal therapy has become possible with these active substances, even for diseases where numerous active substances were already in use. The current understanding about the mechanism of action of monoclonal antibodies allows deep insights into human body and the communication between the different cells, both in the physiological and in the pathological metabolic processes. The aim of this thesis was to report on all monoclonal antibodies that were approved between 2004-2022 and to compare them according to indication areas. The pharmaceutically relevant targets of the active ingredients for an indication area were examined, including the sometimes very complicated mechanisms of action and the resulting medicinal areas of application. An extensive list of references, most of which can be accessed electronically, makes it easier to study this complex subject in depth.

title: Pilotstudie zur Evaluierung des Family Mentoring (FAME) -Programms von Big Brothers Big Sisters Österreich
Creators: name: Pehn, Fiona
Year: 2022

description: Eltern in ihren Erziehungsaufgaben zu unterstützen, zu stärken und zu entlasten, ist das Ziel zahlreicher Eltern- und Familieninterventionsprogramme weltweit. Nur wenige werden jedoch ausreichend auf ihre Wirksamkeit hin überprüft. Die vorliegende Pilotstudie zur Evaluation des Family Mentoring (FAME)-Programms der Organisation Big Brothers Big Sisters Österreich soll dazu beitragen, diese Forschungslücke zu schließen. Im Rahmen der Evaluation wurden die Auswirkungen des Programms auf die teilnehmenden Eltern und Kinder anhand folgender Variablen analysiert: Elterliche Erziehungskompetenzen, Zufriedenheit mit der Elternrolle, elterliche Sensitivität, elterliche Belastung sowie psychisches Wohlbefinden und Selbstwert der Kinder. Bei der durchgeführten Pilotstudie handelt es sich um eine empirische, nicht-experimentelle, quantitative Erhebung ohne Kontrollgruppe zu sechs Messzeitpunkten. Die Stichprobe setzt sich aus n = 10 Elternteilen zusammen, welche das Programm von Oktober 2021 bis Februar 2022 absolviert haben. Die Ergebnisse zeigen keine signifikanten Unterschiede zwischen der Baseline-Messung (T1) und dem letzten Messzeitpunkt nach Abschluss des Programms (T6) hinsichtlich der abhängigen Variablen. Aus der Pilotstudie lassen sich dennoch wertvolle Implikationen für mögliche Folgestudien, wie die Durchführung dieser mit einer größeren Stichprobe, sowie für die Weiterführung des FAME-Programms mit Elterngruppen vor Ort und einer breiteren Zugänglichkeit für Familien mit weniger Ressourcen ableiten.
description: Supporting, strengthening and relieving parents in their parenting tasks is the goal of numerous parenting and family intervention programmes worldwide. However, only a few are sufficiently tested for their effectiveness. The present pilot study on the evaluation of the Family Mentoring (FAME) Programme of the organisation Big Brothers Big Sisters Austria is intended to contribute to closing this research gap. As part of the evaluation, the effects of the programme on the participating parents and children were analysed using the following variables: Parenting skills, satisfaction with the parenting role, parental sensitivity, parental stress as well as psychological well-being and self-esteem of the children. The conducted pilot study is an empirical, non-experimental, quantitative survey without a control group at six measurement points. The sample consists of n = 10 parents who completed the programme from October 2021 to February 2022. The results show no significant differences between the baseline measurement (T1) and the last measurement point after completion of the programme (T6) with regard to the dependent variables. Nevertheless, valuable implications can be drawn from the pilot study for possible follow-up studies, such as conducting these with a larger sample, as well as for the continuation of the FAME Programme with on-site parent groups and wider accessibility for families with fewer resources.
Local Group dSph radio survey with ATCA (II): Non-thermal diffuse emission

description: Our closest neighbours, the Local Group dwarf spheroidal (dSph) galaxies, are extremely quiescent and dim objects, where thermal and non-thermal diffuse emissions lack, so far, of detection. In order to possibly study the dSph interstellar medium, deep observations are required. They could reveal non-thermal emissions associated with the very-low level of star formation, or to particle dark matter annihilating or decaying in the dSph halo. In this work, we employ radio observations of six dSphs, conducted with the Australia Telescope Compact Array in the frequency band 1.1-3.1 GHz, to test the presence of a diffuse component over typical scales of few arcmin and at an rms sensitivity below 0.05 mJy/beam. We observed the dSph fields with both a compact array and long baselines. Short spacings led to a synthesized beam of about 1 arcmin and were used for the extended emission search. The high-resolution data mapped background sources, which in turn were subtracted in the short-baseline maps, to reduce their confusion limit. We found no significant detection of a diffuse radio continuum component. After a detailed discussion on the modelling of the cosmic-ray (CR) electron distribution and on the dSph magnetic properties, we present bounds on several physical quantities related to the dSphs, such that the total radio flux, the angular shape of the radio emissivity, the equipartition magnetic field, and the injection and equilibrium distributions of CR electrons. Finally, we discuss the connection to far-infrared and X-ray observations.

description: Purpose: To investigate how EU related contents are represented in Portuguese upper secondary school textbooks of History and English as a Foreign Language (EFL). Design/methodology/approach: The study performs a textbook analysis on two History textbooks and three EFL textbooks to explore if and how EU related topics are addressed. The methodological approach was mainly qualitative, based on a content analysis of the textbooks, but also includes some quantitative data (e.g., number of paragraphs) to determine the importance given to European topics in each of the selected school subjects. Findings: EFL textbooks have a residual approach to EU topics that is mainly focused in students’ mobility. History textbooks, while containing a significant amount of information about the EU, present it mainly in a non-confrontational perspective and do not prioritize the development of students’ critical thinking about the EU. Our data also points to a predominance of national level citizenship related content, with European citizenship being briefly and normatively presented to the students. Research limitations/implications: EFL is attended by almost 100% of students in the academic track of secondary education, but History is a curricular subject only available to 25-30% of the students; as such, our findings refer to a specific group. Practical implications: Textbooks should include more information about the actual problems and challenges of the EU to foster the development of students’ critical thinking about the EU.

description: We prove the $L^p$ regularity of the weighted Bergman projection on the Hartogs triangle, where the weights are powers of the distance to the singularity at the boundary. The restricted range of $p$ is proved to be sharp. By using a two-weight inequality on the upper half plane with Muckenhoupt weights, we can consider a slightly wider class of weights.

A Vehicle for Post-National Transformation or an Instrument for Interstate Cooperation? European Integration in Slovakia’s Secondary Education Textbooks
Creators: name: Sulikova, Jana
Publisher: name: JSSE - Journal of Social Science Education
Year: 2018

description: Purpose: In light of the public resistance towards the deepening of European integration (EI) and the role that education is anticipated to have in supporting the process, this paper examines the conceptualisation of EI in lower secondary textbooks for History, Geography and Civics. Specifically, the paper asks whether EI is conceived of as a vehicle for the post-national transformation of Europe or as an instrument for interstate cooperation. Design: Drawing on the insights of EI theories and content analysis, the paper adopts a qualitative approach. Applying this approach, the textbooks currently used in Slovakia’s lower secondary schools are analysed as a case study. Findings: The findings are inconclusive with regard to the research question. Indeed, while the sources are positive about EI, the findings suggest some problematic aspects in terms of how the textbooks analysed conceive the nature of the integration process. Research implications: The approach taken in this paper could be replicated on a larger scale in other countries. Practical implications: Curricula and textbook designers ought to consider how to include a critical discussion on the deepening of EI in secondary education.
