A Non-Linear Acoustic Source Mechanism In Gaseous Combustion
Creators: name: Dalamagas, Basile
Publisher: name: London South Bank University
Year: 1985

description: A brief review of previous work on mechanisms of sound generation in turbulent gaseous combustion is presented and concluded that current literature does not adequately describe the noise generating process. The sound emission from acoustically perturbed premixed laminar flames is investigated and related to the flame geometry. An experimental arrangement is described which has enabled three stages in the combustion of small, isolated pockets of a combustible mixture to be distinguished. A theoretical model of the processes involved is given which shows that the three stages may be accounted for in terms of the changing acceleration of the flame front as the geometry of the combustible mixture alters. The model considers an elementary volume of burning gas as a hydrodynamic system with a steadily decreasing volume and surface area. By considering the conservation equations and the Arrhenius equation, and making certain simplifying assumptions, the model predicts that in the final stages of burning, when the flame preheat layer is approximately equal to the radius of the volume, the gas will undergo catastrophic collapse in a small thermal explosion. The model also gives, an expression for the acoustic pressure pulse associated with this thermal explosion. The investigation adds to the mechanisms proposed by other workers for sound emission from turbulent gaseous combustion, describing the final stages of the combustion process with the experimental findings in good qualitative agreement with the theoretical predictions. The limitations of the experiments are discussed. The experimental results themselves lead to the conclusion that the method described may also form the basis for the measurement of physical parameters such as effective activation energies using acoustic techniques.

description: We investigate the angular and kinematic distributions of satellite galaxies around a large sample of bright isolated primaries in the spectroscopic and photometric catalogues of the Sloan Digital Sky Survey (SDSS). We detect significant anisotropy in the spatial distribution of satellites. To test whether this anisotropy could be related to the rotating disks of satellites recently found by Ibata et al. in a sample of SDSS galaxies, we repeat and extend their analysis. Ibata et al. found an excess of satellites on opposite sides of their primaries having anticorrelated radial velocities. We find that this excess is sensitive to small changes in the sample selection criteria which can greatly reduce its significance. In addition, we find no evidence for correspondingly correlated velocities for satellites observed on the same side of their primaries, which would be expected for rotating disks of satellites. We conclude that the detection of coherent rotation in the satellite population in current observational samples is not robust. We compare our data to the $Λ$CDM Millennium simulations populated with galaxies according to the semi-analytic model of Guo et al. We find excellent agreement with the spatial distribution of satellites in the SDSS data and the lack of a strong signal from coherent rotation.

description: How to model economic competencies with the objective of empirically testing them? This question has been discussed for many years now without a conclusive measurement model having been presented thus far. Taking an in-depth analysis of the definition of competency proposed by Weinert (2001) as a starting point, we will derive a framework for the necessary complexity of competency assessment, which finds its graphical representation in a competence octagon. After discussing existing empirical work in the field of economic education and classifying it using the categories of the competence octagon, we will then propose a new model of economic competency that allows for empirical testing.

title: Auseinandersetzung mit der Mühlviertler Menschenhatz und der Zeitzeugin Anna Hackl in Schulen der Umgebung der Gedenkstätte Mauthausen
Creators: name: Voglhofer, Laura
Year: 2022

description: In dieser Masterarbeit beschäftigt sich die Autorin mit der Frage, wie Lehrende in Schulen in der Umgebung der Gedenkstätte Mauthausen die Mühlviertler Menschenhatz als Thema von lokalem Interesse verhandeln, welche Bedeutung hierbei der Zeitzeugin Anna Hackl zugeschrieben wird und wie diese ihre eigene Arbeit wahrnimmt. Um die Fragen zu beantworten, wurde zum einen eine Online-Umfrage mit quantitativen und qualitativen Fragen mit 39 Lehrenden und zum anderen ein qualitatives Interview mit der Zeitzeugin Anna Hackl durchgeführt. Diese wurden mit der qualitativen Inhaltsanalyse nach Mayring ausgewertet. Es stellte sich heraus, dass Lehrende vor allem durch Erzählungen und Diskussionen das Interesse an lokalen historischen Ereignissen wecken wollen. Dabei scheint Anna Hackl eine wichtige Rolle zugewiesen zu werden: Während sie selbst angibt, im Jahr 2019 über 50 Vorträge gehalten zu haben, geht aus der Umfrage hervor, dass zwei Drittel der befragten Lehrenden eine Live-Begegnungen mit Anna Hackl initiieren. Die Lehrpersonen sehen vor allem in der Authentizität der Zeitzeugin, der Emotionalisierung und dem Fassbar-Werden von Geschichte einen Vorteil für historisches Lernen. Jedoch scheint die Verfügbarkeit von Zeitzeug:innen eine große Herausforderung darzustellen.

description: Ce mémoire professionnel traite des questions de discipline, dans un contexte plus global de gestion de classe. Tout d’abord, il s’intéresse aux pratiques préventives des enseignants : cohésion de groupe, autorité dans la relation pédagogique, règles de vie et renforcement positif. Ensuite, il traite des sanctions : punition et sanction éducative. Nous utilisons le terme punition pour décrire une sanction donnée dans l’unique but d’obtenir le calme en classe. En opposition, la sanction éducative est donnée dans le but de responsabiliser l’élève pour qu’il ne réitère pas. Par conséquent, nous nous posons la question de recherche suivante : comment deux enseignantes vaudoises sanctionnent-elles les transgressions des règles de vie de la classe ? Deux hypothèses découlent de notre travail de recherche que nous confirmons ou réfutons dans la synthèse des résultats concernant chaque enseignante et dans la conclusion. Les voici : deux enseignantes vaudoises sanctionnent dans un but éducatif les transgressions des règles de vie de la classe ; les élèves de ces deux classes ne perçoivent pas la finalité éducative des sanctions données par leur enseignante. Pour récolter les données, nous observons, tout d’abord, plusieurs moments d’enseignement en stage. Puis, nous menons un entretien individuel avec chacune de nos praticiennes formatrices pour les interroger sur leurs différentes pratiques. Ensuite, nous questionnons un tiers des élèves, ce qui correspond à six élèves de chaque classe, dans le but de clarifier certains éléments concernant la construction des règles de vie et les sanctions de leurs enseignantes.

description: We report femtosecond resonant soft X-ray diffraction measurements of the dynamics of the charge order and of the crystal lattice in non-superconducting, stripe-ordered La1.875Ba0.125CuO4. Excitation of the in-plane Cu-O stretching phonon with a mid-infrared pulse has been previously shown to induce a transient superconducting state in the closely related compound La1.675Eu0.2Sr0.125CuO4. In La1.875Ba0.125CuO4, we find that the charge stripe order melts promptly on a sub-picosecond time scale. Surprisingly, the low temperature tetragonal distortion is only weakly reduced, reacting on significantly longer time scales that do not correlate with light-induced superconductivity. This experiment suggests that charge modulations alone, and not the LTT distortion, prevent superconductivity in equilibrium.

description: The following contribution makes an effort to place the concept-cartoon-method into the context of social science education. Concept-cartoons (CCs) enable teachers to use the everyday life experiences and individual thoughts of the pupils as a positive enrichment tool within the learning processes. In this context, CCs are very suitable to function as a method to gain information about both the existing mental conceptions and the individual political judgment strategies. Through this, it is possible to put everyday life concepts and scientific knowledge in a constructive relationship, which finally enhances new learning objectives. First the article highlights the relevance of pupils’ and teachers` concepts for judgment processes. On this basis the method of CCs is introduced and evaluated Der folgende Artikel beschäftigt sich mit den Möglichkeiten des methodischen Einsatzes von Concept-Cartoons im Rahmen sozialwissenschaftlichen Unterrichts. Als Instrumentarium zur Diagnose von Schülervorstellungen und individuellen Urteilsstrategien, bieten Comic-Cartoons den Lehrkräften die Möglichkeit, den Unterricht entlang dieser lernrelevanten Perspektiven zu gestalten. Durch die konstruktive Verknüpfung von Alltagskonzepten und Fachkonzepten können auf diese Weise neue Chancen für nachhaltige Lehr- und Lernprozesse erschlossen werden. Innerhalb dieses Beitrags wird zunächst die Bedeutung von Schülervorstellungen und vorfachlichen Urteilsstrategien für wirksamen sozialwissenschaftlichen Unterricht geklärt. Im Anschluss erfolgt eine Einführung in die Methode „Concept-Cartoons“. Abschließend werden exemplarisch drei von den Autoren gestaltete Cartoons vorgestellt.

description: Understanding the interaction of vortices with inclusions in type-II superconductors is a major outstanding challenge both for fundamental science and energy applications. At application-relevant scales, the long-range interactions between a dense configuration of vortices and the dependence of their behavior on external parameters, such as temperature and an applied magnetic field, are all important to the net response of the superconductor. Capturing these features, in general, precludes analytical description of vortex dynamics and has also made numerical simulation prohibitively expensive. Here we report on a highly optimized iterative implicit solver for the time-dependent Ginzburg-Landau equations suitable for investigations of type-II superconductors on massively parallel architectures. Its main purpose is to study vortex dynamics in disordered or geometrically confined mesoscopic systems. In this work, we present the discretization and time integration scheme in detail for two types of boundary conditions. We describe the necessary conditions for a stable and physically accurate integration of the equations of motion. Using an inclusion pattern generator, we can simulate complex pinning landscapes and the effect of geometric confinement. We show that our algorithm, implemented on a GPU, can provide static and dynamic solutions of the Ginzburg-Landau equations for mesoscopically large systems over thousands of time steps in a matter of hours. Using our formulation, studying scientifically-relevant problems is a computationally reasonable task.

description: Do domain specific teaching/learning beliefs and epistemological beliefs exist and do they explain a domain specific approach to teaching and learning the social sciences? This paper reports on the first stage of an exploratory qualitative study carried out at the University of Bielefeld in 2010/11 on pre-service social studies teachers (PSST, n=61). It has a threefold aim: First, providing a very short overview of relevant trends in recent research on epistemological beliefs and teaching/learning beliefs and presenting some plausible hypotheses on if and how these belief dimensions are related to each other in the field of social studies education; second, presenting and discussing metaphors as a suitable qualitative research method for diagnosing and analysing the teaching and learning beliefs in the field; third, presenting the general outline of the Bielefeld project and a comparison of two emblematic cases of the project to evaluate the potential advantages and shortcomings of the research design and methods, especially of metaphor analysis.

Citizenship Education: Lithuanian Mapping
Creators: name: Zaleskene, Irena
Publisher: name: JSSE - Journal of Social Science Education
Year: 2011

description: Some theoretical concepts of globalisation and citizenship are discussed in the article as well as changing role of citizenship education in transforming Lithuanian Society. The author points out that many problems in contemporary Lithuanian society arise from the fact that the relationship between individuals and the state is changing fundamentally. The state should broaden “positive” choices and support an individual by ensuring principles of equality in basic human rights and access to opportunities. On the other hand, an individual has to take the responsibility for his/her own life becoming a decisive factor in choosing personal life style and in building up civic community. In this respect, it is expected that Citizenship Education would lay an important role in educating competence and attitudes towards own responsibilities, in educating mental and practical skills for positive civic participation. Current status and new approaches of citizenship education in Lithuania are presented in the light of international developments. The article concludes that changing role of citizenship education has significant implications for professional development of teachers and for the national teacher training system as a whole.

description: The first law of thermodynamics imposes not just a constraint on the energy-content of systems in extreme quantum regimes, but also symmetry-constraints related to the thermodynamic processing of quantum coherence. We show that this thermodynamic symmetry decomposes any quantum state into mode operators that quantify the coherence present in the state. We then establish general upper and lower bounds for the evolution of quantum coherence under arbitrary thermal operations, valid for any temperature. We identify primitive coherence manipulations and show that the transfer of coherence between energy levels manifests irreversibility not captured by free energy. Moreover, the recently developed thermo-majorization relations on block-diagonal quantum states are observed to be special cases of this symmetry analysis.

description: In this paper, we propose a novel, effective and fast method to obtain a color illumination invariant and shadow-free image from a single outdoor image. Different from state-of-the-art methods for shadow-free image that either need shadow detection or statistical learning, we set up a linear equation set for each pixel value vector based on physically-based shadow invariants, deduce a pixel-wise orthogonal decomposition for its solutions, and then get an illumination invariant vector for each pixel value vector on an image. The illumination invariant vector is the unique particular solution of the linear equation set, which is orthogonal to its free solutions. With this illumination invariant vector and Lab color space, we propose an algorithm to generate a shadow-free image which well preserves the texture and color information of the original image. A series of experiments on a diverse set of outdoor images and the comparisons with the state-of-the-art methods validate our method.

description: This paper considers the role of conflict (its constitutive relevance or erasure) in the concepts and practices of democracy and citizenship. Critically reflecting on contexts of formal and non-formal political education, and on the observed practices and discourse of relevant educational actors, we intend to interrogate the school’s conceptions, misconceptions and/or contradictions around democracy and political participation. Focusing on the arguments surrounding the perspectives oriented towards consensus vs. those embracing dissensus in social and political theories, this article considers the implicit and explicit powers existent or generated in school relationships, which inevitably affect our ways of looking at citizenship and of educating politically Cet article prétend aborder le rôle du conflit (du point de vue de sa pertinence constitutive ou de son effacement) dans des conceptions et des pratiques de la démocratie ou citoyenneté. Sur la base d’une réflexion critique touchant aux concepts d’éducation politique formelle ou non-formelle, ainsi qu’aux pratiques et discours d’agents centraux de l’action éducationnelle qui ont pu être observés, nous prétendons identifier des concepts, malentendus et/ou contradictions ayant trait aux concepts de démocratie et de participation politique. En examinant les perspectives visant à atteindre un consensus opposées à l’ampleur des divergences au coeur des théories politiques et sociales, cet article se focalise sur des pouvoirs implicites ou explicites, présentifiés ou générés dans des relations scolaires, qui affectent inévitablement notre manière d’envisager la citoyenneté, ainsi que l’action d’éduquer politiquement.

description: Postulated by Pauli to explain the electronic structure of atoms and molecules, the exclusion principle establishes an upper bound of 1 for the fermionic natural occupation numbers $\{n_i\}$. A recent analysis of the pure $N$-representability problem provides a wide set of inequalities for the $\{n_i\}$, leading to constraints on these numbers. This has a strong potential impact on reduced density matrix functional theory as we know it. In this work we continue our study the nature of these inequalities for some atomic and molecular systems. The results indicate that (quasi)saturation of some of them leads to selection rules for the dominant configurations in configuration interaction expansions, in favorable cases providing means for significantly reducing their computational requirements.

description: Depuis quelques décennies et suite à plusieurs mouvements sociaux du XXe siècle, la préoccupation de savoir comment adapter la transmission de connaissances à une diversité d’apprenants n’a cessé de faire évoluer la forme scolaire. De nos jours, le concept d’école inclusive occupe une place importante car c’est le modèle vers lequel tendent beaucoup de systèmes éducatifs, dont celui de la Suisse actuellement dans une logique d’intégration. Différents concepts, tels que la différenciation pédagogique ou la pédagogie universelle, s’articulent autour de cette volonté institutionnelle qui est d’inclure tous les élèves dans un milieu scolaire ordinaire. Toutefois, les mesures mises en place pour accueillir des élèves ayant des besoins éducatifs particuliers semblent ne pas profiter à tous. Malgré les injonctions légales stipulant que chaque élève doit être mis en situation d’atteindre son plein potentiel, un décalage subsiste entre le projet visé par l’école inclusive et la réalité du terrain : l’attention semble davantage portée sur les catégories d’élèves ayant des difficultés alors que la diversité des apprenants inclut aussi les élèves ayant de grandes facilités. Pour expliquer cette rupture au niveau des pratiques pédagogiques, de nombreux ouvrages rendent compte de la place déterminante qu’occupent les conceptions enseignantes et institutionnelles, notamment vis-à-vis des notions de différenciation pédagogique, d’école inclusive, mais aussi d’intelligence et de handicap. Le phénomène de catégorisation des enfants, largement répandu dans la documentation scientifique, influence l’enseignant dans sa perception des apprenants. Ceux ayant de grandes facilités d’apprentissage n’échappent pas à ce constat : aucune littérature ne leur est directement associée, si bien que les ressources à disposition des enseignants ne concernent que les enfants diagnostiqués HPI.
Citizenship Education and Curriculum Development in Nigeria

description: The article highlights the evolutionary trends of citizenship education in Nigeria. The 1914 British amalgamation of erstwhile Northern and Southern Protectorates gave birth to Nigeria as a state. The disparage ethnic composition of the new state, especially after independence, necessitated finding a common ground to promote committed citizens, against primordial ethnic cleavages and indigenization. It is not therefore surprising that the role of education in fostering national citizenship and consciousness was emphasized. Initially, social studies was used as a curriculum framework, until lately when a new subject, civics, was created in primary and junior secondary schools. The author considers the historical, cultural and political context underlining these curricular changes and identifies the current and future challenges face by the implementation of Civics curricular in Nigerian schools.

description: Inspired by the great development of graphene, more and more works have been conducted to seek new two-dimensional (2D) materials with Dirac cones. Although 2D Dirac materials possess many novel properties and physics, they are rare compared with the numerous 2D materials. To provide explanation for the rarity of 2D Dirac materials as well as clues in searching for new Dirac systems, here we review the recent theoretical aspects of various 2D Dirac materials, including graphene, silicene, germanene, graphynes, several boron and carbon sheets, transition metal oxides (VO2)n/(TiO2)m and (CrO2)n/(TiO2)m, organic and organometallic crystals, so-MoS2, and artificial lattices (electron gases and ultracold atoms). Their structural and electronic properties are summarized. We also investigate how Dirac points emerge, move, and merge in these systems. The von Neumann-Wigner theorem is used to explain the scarcity of Dirac cones in 2D systems, which leads to rigorous requirements on the symmetry, parameters, Fermi level, and band overlap of materials to achieve Dirac cones. Connections between existence of Dirac cones and the structural features are also discussed.

description: For some monoids, we give a method of composing invertibility preserving maps associated to "partial involutions." Also, we define the notion of "determinants for finite dimensional algebras over a field." As examples, we give invertibility preserving maps for Clifford algebras into a field and determinants for Clifford algebras into a field, where we assume that the algebras are generated by less than or equal to 5 generators over the field. On the other hand, "determinant formulas for Clifford algebras" are known. We understand these formulas as an expression that connects invertibility preserving maps for Clifford algebras and determinants for Clifford algebras. As a result, we have a better sense of determinant formulas. In addition, we show that there is not such a determinant formula for Clifford algebras generated by greater than 5 generators.

Year: 2022

description: In der hier vorliegenden Arbeit wurde der Frage nachgegangen, inwiefern sich Liebe und Ökonomie in den Volksstücken von Ödön von Horváth gegenseitig beeinflussen. Dafür wurde zunächst das Zeitgeschehen beleuchtet, um einen Einblick in die damalige wirtschaftliche Lage zu geben. Anschließend wurde ein Versuch unternommen, den abstrakten Begriff Liebe im Horváth´schen Kontext zu konkretisieren. Anhand dieser theoretischen Vorarbeit wurden die Volksstücke unter dem Aspekt der ökonomischen Liebe untersucht. Konkret handelte es sich dabei um folgende Stücke: Die Bergbahn, Italienische Nacht, Geschichten aus dem Wiener Wald, Kasimir und Karoline, Glaube Liebe Hoffnung; Die Analyse ergab, dass die ökonomische Liebe in unterschiedlicher Weise thematisiert wird. Während sie vor allem in den drei zuletzt genannten Stücken einen konstitutiven Aspekt darstellt, spielt sie in den anderen Volksstücken eine untergeordnete Rolle. Somit lässt sich festhalten, dass in Geschichten aus dem Wiener Wald, Kasimir und Karoline und Glaube Liebe Hoffnung die Liebe stark von der Ökonomie beeinflusst wird.

description: We experimentally explore the state space of three qubits on an NMR quantum information processor. We construct a scheme to experimentally realize a canonical form for general three-qubit states up to single-qubit unitaries. This form involves a non-trivial combination of GHZ and W-type maximally entangled states of three qubits. The general circuit that we have constructed for the generic state reduces to those for GHZ and W states as special cases. The experimental construction of a generic state is carried out for a nontrivial set of parameters and the good fidelity of preparation is confirmed by complete state tomography. The GHZ and W-states are constructed as special cases of the general experimental scheme. Further, we experimentally demonstrate a curious fact about three-qubit states, where for almost all pure states, the two-qubit reduced states can be used to reconstruct the full three-qubit state. For the case of a generic state and for the W-state, we demonstrate this method of reconstruction by comparing it with the directly tomographed three-qubit state.

State-Orchestrated Civic Education versus Civic Competencies of School Students: Some Conceptual Implications from a National Case Study
Creators: name: Dimitrov, Georgi
Publisher: name: JSSE - Journal of Social Science Education
Year: 2011

description: Imagine a situation in which civic education has been enforced and practiced for nearly a decade and, as a result, the civic competences of the young people have dramatically decreased as compared with the previous national level. This situation is not a fictional one. It depicts the findings of a cross-national longitudinal survey. How come a generation which had not been exposed to the influence of civic education performed better in civic competences as compared with their followers a decade later? Who is to blame? The school teachers – for not having fulfilled their obligations? The school system – for failing to accomplish its socialization task? Or the particular civic education program – for being fake or ill-designed? Or may be we, the social scientists, have been unduly naïve about our expectations of civic education and its implementation in schools? The more important question is: to what extent does civic education fit in naturally with school life without clashing with it? Or put in another way, isn’t the classical tradition in the modern school essentially in contradiction with civic education? This problem takes the particular (Bulgarian) case beyond the boundaries of its national specificityand situates it at the level of a much more general question of the limits and preconditions of applicability of civic education, especially in regard to the expectation that it will form active citizens, capable of improving the democratic self-regulation of modern societies. The paper argues that the results of civic education should not be assessed in abstract form apart from the major factors concerning the socio-cultural, institutional and educational context. They are significantly dependent on the character of the national curriculum and the socialization programme specific for each country. Furthermore, schools, in their turn, are highly dependent on the role of civil society in the respective national societies, which feature vastly varying political cultures. The large portion of very low education achievements cannot be adduced to civic education per se, but to the wider alienation of young people from school life.

description: Angesichts dessen, dass von der deutschsprachigen Literaturwissenschaft als auch von der Literaturkritik eine Häufung an Provinztexten konstatiert wurde, widmet sich die vorliegende Arbeit der Frage, was Provinz überhaupt ist und wodurch sie in literarischen Texten erkenn-bar gemacht wird. Gegenwartsromane stehen im Zentrum dieser Untersuchungen, doch für die Weltliteratur bildet die Provinz bzw. die Vorstellung einer Provinz seit jeher ein Faszino-sum. Die Provinz bereichert als Handlungsraum, Weltenmodell und Allegorie die Möglich-keiten des Erzählens. Manche Merkmale und Konnotationen der Provinz haben sich im Laufe der Zeit verändert. Was ihr bis heute bleibt, ist die Eigenschaft, nur als Teil einer Dichotomie zu existieren. Es gibt keine Provinz ohne einen nichtprovinziellen Gegenraum. Vornehmlich werden die Stadt als die Nicht-Provinz und das Land als Provinz zu diesen entgegengesetzten Räumen erklärt. Gerade die Annahme, dass ein dörflicher, ländlicher oder generell metropo-lenferner Erzählraum auschlaggebendes Kriterium sei für eine literarische Provinz, wird in dieser Arbeit infrage gestellt. Umso mehr rücken Bewertungen und zugeschriebene Charak-tereigenschaften in den Fokus, welche die Provinz und die Menschen in der Provinz kenn-zeichnen. Darüber hinaus sind für das literarische Medium spezifische Ausdrucksformen von Sprache und Zeit relevant, um Provinz hervorzurufen. Weil die Provinz kaum durch eindeutige Raumgrenzen festgelegt werden kann, sind münd-liche und schriftliche Erzählungen umso entscheidender, um Provinz zu definieren. Die in dieser Arbeit herangezogenen Erzählungen stammen fast ausschließlich aus Prosawerken der deutschsprachigen Literatur. Zahlreiche Beispiele aus verschiedenen Texten erörtern die Mannigfaltigkeit dessen, was Provinz ist und sein kann. In besonderer Breite wird der Begriff Provinz anhand der Romane Koala (2014) von Lukas Bärfuss und Einladung an die Waghal-sigen (2010) von Dorothee Elmiger analysiert. Die eingehenden Textinterpretationen beleuch-ten die Provinz als Verzahnung von Raumvorstellungen, Charaktereigenschaften, hierarchisch geprägten Bewertungen, Verwendung von Sprache und Zeitempfinden. Die Arbeit stützt sich auf Erkenntnissen der Forschung zur sogenannten Provinzliteratur, welche erweitert und kritisch ausgeführt werden. Eingehender als andere Beiträge werden vor allem positive und negative Bewertungen der Provinz hervorgehoben. In der Textgestaltung können diese Bewertungen vielseitig auftreten und sind in jedem Fall bestimmend für den Provinzbegriff. Damit ist die Vorstellung von Provinz derart heterogen, dass sie als Imagina-tion verstanden werden darf, die als Erzählung tradiert wird und dabei immer wieder eine Umgestaltung erfährt.

description: Cette étude tente de répondre à la question de recherche suivante : « Est-ce que la pratique musicale, en milieu scolaire, peut favoriser une progression des élèves de 8 à 10 ans au niveau de leurs capacités de lecture à haute voix, notamment en rapport au rythme, à l’intonation et à l’expression ? ». J’ai mis en place un dispositif dans deux classes : l’une d’elle me servant de groupe témoin et l’autre de groupe expérimental bénéficiant de la séquence musicale pendant 6 semaines. Afin de m’appuyer sur une base théorique solide, j’ai questionné le lien entre la musique et le langage dans la littérature. Le concept de « Musilanguage » de Brown (2000) détermine que ces deux paradigmes ont une base ancestrale commune avant de s’identifier par leurs caractéristiques individuelles. Ma recherche s’oriente au niveau du rythme impliqué par les signes de ponctuation, tout comme pour l’intonation, ainsi que l’expression dans la lecture à haute voix. Au niveau du rythme, Brunet (2016) définit qu’à l’approche d’une virgule, il faut effectuer une « faible pause ». Contrairement au point et au point d’interrogation qui impliquent un « arrêt ferme ». Pour travailler cette différence rythmique, des gestes leur ont été associés, dans le but d’un transfert des apprentissages. Les résultats montrent une volonté plus marquée du groupe expérimental à effectuer les silences propres aux signes de ponctuation, lors du post-test. Quant à l’intonation des phrases définies par Di Cristo (2016), notre hypothèse s’est confirmée. La pratique musicale, à travers les courbes mélodiques et les gestes indiquant les variations de hauteur, a permis d’améliorer l’intonation dans la lecture à haute voix du groupe expérimental entre 12% et 25%. Pour terminer, les résultats des élèves concernant l’expression de leur lecture, montre aussi une progression plus importante pour le groupe expérimental que pour le groupe témoin. Les productions sonores effectuées lors des leçons musicales semblent être favorables à l’interprétation des lectures des élèves.
Bartnik's mass and Hamilton's Modified Ricci Flow

description: We provide estimates on the Bartnik mass of constant mean curvature (CMC) surfaces which are diffeomorphic to spheres and have positive mean curvature. We prove that the Bartnik mass is bounded from above by the Hawking mass and a new notion we call the asphericity mass. The asphericity mass is defined by applying Hamilton's modified Ricci flow and depends only upon the restricted metric of the surface and not on its mean curvature. The theorem is proven by studying a class of asymptotically flat Riemannian manifolds foliated by surfaces satisfying Hamilton's modified Ricci flow with prescribed scalar curvature. Such manifolds were first constructed by the first author in her dissertation conducted under the supervision of M.T. Wang. We make a further study of this class of manifolds bounding the ADM masses of such manifolds and analyzing the rigid case when the Hawking mass of the inner surface of the manifold agrees with its ADM mass. New in 2020: After this paper was published, Hyun-Chul Jang observed that we dropped a term in our calculations. Tracking the consequences throughout, we see that we need only slightly change the definition of the asphericity mass and then all statements of our theorems, propositions, and lemmas remain the same as the published version with slight revisions to the proofs. Pengzi Miao observed we needed an assumption on Gauss curvature in Theorem 1. We include these corrections and also some clarifications where they are needed in blue. Both Hyun-Chul Jang and Pengzi Miao have approved of our corrections and we have sent an erratum to the journal.

No Longer Just a Victim: Towards an Inclusive Model of Human Rights Education that Respects the Rights of Sexual and Gender Minority Children
Creators: name: ONGSUPANKUL, WARISA
Publisher: name: Monash University
Year: 2022
Subjects: International humanitarian and human rights law

description: This thesis analyses the ways in which an inclusive learning environment can be created where sexual and gender minority (SGM) children can bring their whole self to school. It considers how international human rights law, in particular Article 29 of the CRC, relating to human rights education (HRE), together with the capability approach can be used to enhance the school experience and well-being of SGM children. This analysis, through the case study of Thailand’s educational policies and practices, informs the development of the model which proposes seven elements for the effective implementation of HRE that is inclusive of SGM children.
Turkey’s New Citizenship and Democracy Education Course: Search for Democratic Citizenship in a Difference-Blind Polity?

description: The paper introduces and critically evaluates the new Citizenship and Democracy Education course in the Turkish curriculum. This course has been introduced as a mandatory subject in grade 8 per one hour a week in the 2011-2012 academic year. Following the comprehensive 2005 curriculum reform, Citizenship and Human Rights Education courses had been abolished and these themes had been distributed to the curriculum of different courses. However, recommendations of academics and international bodies such as the Council of Europe on the advantages of having a distinct course on citizenship and human rights have led the Ministry of National Education to reintroduce a compulsory course covering these themes. The new course seems to be a human rights education course with its emphasis on rights and responsibilities. It could be considered a progressive step in this regard. However, the implication that educating people about their rights could be a basis of democratic citizenship might not be realized in present Turkey where internal conflicts based on religious, ethnic and language-based differences are becoming salient. The paper argues that democratization of citizenship in Turkey requires not only an education about rights but also the questioning of the current difference-blind civic republican notion of citizenship. It draws attention to the necessity of the development of a new political framework and a related citizenship course that would allow for peaceful coexistence of cultural differences.

description: A vast amount of OpenCourseWare (OCW) is meanwhile being published online to make educational content accessible to larger audiences. The awareness of such courses among users and the popularity of systems providing such courses are increasing. However, from a subjective experience, OCW is frequently cursory, outdated or non-reusable. In order to obtain a better understanding of the quality of OCW, we assess the quality in terms of fitness for use. Based on three OCW use case scenarios, we define a range of dimensions according to which the quality of courses can be measured. From the definition of each dimension a comprehensive list of quality metrics is derived. In order to obtain a representative overview of the quality of OCW, we performed a quality assessment on a set of 100 randomly selected courses obtained from 20 different OCW repositories. Based on this assessment we identify crucial areas in which OCW needs to improve in order to deliver up to its promises.

Automated metadata matching for reference linking

description: Reference linking, or the annotation of references with Digital Object Identifier (DOIs) information, is an important step in academic writing that affects not only whether proper attribution to relevant works is given, but also the computation of research assessment metrics that can impact one's academic career prospects. However, manually linking all references in every manuscript is a highly time-consuming task. In this project, we explore automatic solutions that are based on lexical similarity and semantic similarity in the metadata of references and papers, and curate a corpus of 33 million references from 5.3 million PubMed Central Open Access papers for benchmarking purposes. We find lexical methods to be very accurate, with the best version having a miss rate of only 0.14% during testing, but that semantic methods can have comparable performance while being over 20 times faster under the inference setting. The best semantic method also recommends links that are more relevant to the ground-truth paper as measured by the average ROUGE-F1 of abstracts, which is useful for providing readers with similarly interesting alternative content when the ground-truth paper is unavailable. In summary, we show that semantic similarity is a promising basis for automated reference linking that strikes a good balance between precision, recall, speed, and recommending relevant alternatives.
