description: Hidden-variable models aim to reproduce the results of quantum theory and to satisfy our classical intuition. Their refutation is usually based on deriving predictions that are different from those of quantum mechanics. Here instead we study the mutual compatibility of apparently reasonable classical assumptions. We analyze a version of the delayed-choice experiment which ostensibly combines determinism, independence of hidden variables on the conducted experiments, and wave-particle objectivity (the assertion that quantum systems are, at any moment, either particles or waves, but not both). These three ideas are incompatible with any theory, not only with quantum mechanics.

description: For a non-empty ground set $X$, finite or infinite, the {\em set-valuation} or {\em set-labeling} of a given graph $G$ is an injective function $f:V(G) \to \mathcal{P}(X)$, where $\mathcal{P}(X)$ is the power set of the set $X$. A set-indexer of a graph $G$ is an injective set-valued function $f:V(G) \to \mathcal{P}(X)$ such that the function $f^{\ast}:E(G)\to \mathcal{P}(X)-\{\emptyset\}$ defined by $f^{\ast}(uv) = f(u){\ast} f(v)$ for every $uv{\in} E(G)$ is also injective, where $\ast$ is a binary operation on sets. An integer additive set-indexer is defined as an injective function $f:V(G)\to \mathcal{P}({\mathbb{N}_0})$ such that the induced function $f^+:E(G) \to \mathcal{P}(\mathbb{N}_0)$ defined by $f^+ (uv) = f(u)+ f(v)$ is also injective, where $\mathbb{N}_0$ is the set of all non-negative integers. In this paper, we critically and creatively review the concepts and properties of integer additive set-valued graphs.

Civic Education in Estonia: Democratic or Authoritarian
Creators: name: Haav, Karel
Publisher: name: JSSE - Journal of Social Science Education
Year: 2008

description: The paper distinguishes between traditional formal and social theoretical concepts in education for democracy. On this basis, both Estonian and EU civic education systems are critically analysed. In both cases, the political literacy is not covered with adequate social theoretical concepts. Traditionally, there is a formal description of main political institutions outside of real social relations. Many social scholars have revealed that such an education but contributes to reproduction of the existing social structures. The Author develops a social theoretical approach to democracy and civic education. It relies on main social dichotomies like that of social actors and social structures, and institutional organization theory. It defines main social actors and models of decision making in main social spheres (economy, politics and education). These concepts are linked to social values (individual freedom and prosperity or social equality, solidarity and well-being) and social outcomes (effectiveness and justice). The author also uses these concepts to describe and analyze his students’ democratic knowledge, attitudes and experiences. An integration of social theoretical concepts and practices enables to achieve the ideal goals of democracy education. The paper also critically evaluates the existing civic education system (syllabus, textbooks and national examinations) in Estonia. The system focuses on delivery of some arbitrary texts. In schools with Russian instruction, the authoritarian Estonian civic education strengthens the authoritarian national attitudes of Russian students. As a result, it counteracts to the national integration of Russian students with the Estonian state.

Transition to Democracy and Citizenship Education in Portugal: Changes and Continuities in the Curricula and in Adolescents’ Opportunities for Participation

description: The intense historical transformations in Portugal during the last 30 years have had a profound impact on the educational system and on its role in citizenship education. During this period, Portugal experienced dictatorship, the last socialist revolution in Europe (1974), the end of colonial empire and of colonial wars, the stabilization of a democratic regime and the entrance in the European Economic Community later to be trans-formed into the European Union. Such deep social and political transformation had strong implications in education and its mission in promoting democratic citizenship has been intensively discussed, with fears of ideological inculcation and a tension between conservative vs. emancipatory goals underpinning the curricular decisions in the field. This paper considers these transformations and articulates them with the perspective of adolescents in basic and secondary education regarding citizenship, politics and civic engagement and the actual opportunities for participation they feel they have in the family, the school, and the community. The bases for this discussion are two studies with Portuguese adolescents: the IEA Civic Education Study that involves three national representative samples of students from grade 8, 9 and 11; and a longitudinal study (2005-07) with adolescents from grades 9, 10 and 11. Results from both studies show a tendency for a dissatisfaction/distrust that young people have in relation to key-institutions of democracy (government, political parties) but, at the same time, the valuing of active citizenship and the emergence of new forms of participation. That oxymoron appears as a challenge to both researchers and teachers that might take advantage in being more aware of the quality of youngsters’ participation experiences in their various life contexts.

description: Identification of genes that initiate cell anomalies and cause cancer in humans is among the important fields in the oncology researches. The mutation and development of anomalies in these genes are then transferred to other genes in the cell and therefore disrupt the normal functionality of the cell. These genes are known as cancer driver genes (CDGs). Various methods have been proposed for predicting CDGs, most of which based on genomic data and based on computational methods. Therefore, some researchers have developed novel bioinformatics approaches. In this study, we propose an algorithm, which is able to calculate the effectiveness and strength of each gene and rank them by using the gene regulatory networks and the stochastic analysis of regulatory linking structures between genes. To do so, firstly we constructed the regulatory network using gene expression data and the list of regulatory interactions. Then, using biological and topological features of the network, we weighted the regulatory interactions. After that, the obtained regulatory interactions weight was used in interaction structure analysis process. Interaction analysis was achieved using two separate Markov chains on the bipartite graph obtained from the main graph of the gene network. To do so, the stochastic approach for link-structure analysis has been implemented. The proposed algorithm categorizes higher-ranked genes as driver genes. The efficiency of the proposed algorithm, regarding the F-measure value and number of identified driver genes, was compared with 23 other computational and network-based methods.

"Still Underexposed"? – Some Remarks On The Problematic Relationship Between Visual Communication, Political Science, and Civic Education
Creators: name: Drechsel, Benjamin
Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: Political science in the German-speaking world is only concerned peripherally with pictures. In the course of the “iconic turn” during the 1990s visual political communication became an issue of more weight, but other disciplines like art history still have more competence when it comes to analysing pictures. Thus, the basic question remains: How can we achieve a sustainable “iconic turn” in political science and civic education? The article proposes an answer in three parts: Its first chapter describes the relationship between political science, civic education, and visual communication in the German-speaking world. The effort to map this scattered research landscape ought to be a contribution to its transnational connectivity. The second part reflects on the special “power of pictures”. It argues that pictures probably have specific persuasive power, but nonetheless are neutral political tools (just like words). Obviously they can be exploited by liars, but quite as well they can serve as helpful information resources (e.g. in civic education). Finally, the third chapter claims that political science should try and learn from visually more competent disciplines like art history or communication science. All in all this leads to the final conclusion that political communication research should turn its attention to pictoriality.

description: Minimizing cross-entropy over the softmax scores of a linear map composed with a high-capacity encoder is arguably the most popular choice for training neural networks on supervised learning tasks. However, recent works show that one can directly optimize the encoder instead, to obtain equally (or even more) discriminative representations via a supervised variant of a contrastive objective. In this work, we address the question whether there are fundamental differences in the sought-for representation geometry in the output space of the encoder at minimal loss. Specifically, we prove, under mild assumptions, that both losses attain their minimum once the representations of each class collapse to the vertices of a regular simplex, inscribed in a hypersphere. We provide empirical evidence that this configuration is attained in practice and that reaching a close-to-optimal state typically indicates good generalization performance. Yet, the two losses show remarkably different optimization behavior. The number of iterations required to perfectly fit to data scales superlinearly with the amount of randomly flipped labels for the supervised contrastive loss. This is in contrast to the approximately linear scaling previously reported for networks trained with cross-entropy.

Election Media and Youth Political Engagement
Creators: name: Owen, Diana
Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: Election campaigns are regular opportunities for heightened political engagement and socialization. For many young people, politics becomes most visible and concrete during electoral contests. However, campaign media, at least in the United States, typically have not targeted young voters with messages that enhance their participation and turnout. In fact, much traditional election media coverage of youth has emphasized their lack of interest and involvement, and thus works to discourage the development of activist political orientations. With the evolution of new types of dynamic and populist media formats, such as blogs and social/political networking websites, young people have greater opportunities to establish a presence in election campaigns on their own terms. This piece will explore how new developments in campaign media are changing the relationship of young people to the electoral process.

description: Bohmian mechanics was designed to give rise to predictions identical to those derived by standard quantum mechanics, while invoking a specific interpretation of it - one which allows the classical notion of a particle to be maintained alongside a guiding wave. For this, the Bohmian model makes use of a unique quantum potential which governs the trajectory of the particle. In this work we show that this interpretation of quantum theory naturally leads to the derivation of interesting new phenomena. Specifically, we demonstrate how the fundamental Casimir-Polder force, by which atoms are attracted to a surface, may be temporarily suppressed by utilizing a specially designed quantum potential. We show that when harnessing the quantum potential via a suitable atomic wavepacket engineering, the absorption by the surface can be dramatically reduced. This is proven both analytically and numerically. Finally, an experimental scheme is proposed for achieving the required shape for the atomic wavepacket. All these may enable new insights into Bohmian mechanics as well as new applications to metrology and sensing.

Escaping the Disenchantment Trap: The Effects of a Tailored Campaign on Motivation and Participation of Young German Voters
Creators: name: Rössler, Patrick
Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: Youth surveys permanently prove a general disenchantment with politics and politicians, leading to a decrease in participation and, as a consequence, a drop in voter turnout. Threatening the foundations of our democratic society, it is assumed that one way to get out of this vicious circle can be to enhance motivation and self-efficacy among young adults. This study looks at the potential of tailored campaigns that make politics visible for first-time voters, in order to increase their knowledge about current affairs, interest in political issues, and, subsequently, the willingness to vote. On occasion of the elections held for both the State and the European parliament in 2004, effects of a specially designed campaign were tested in a quasi-experimental design. 128 students of different high schools and vocational schools in the German state Thuringia obtained a 90-minute course unit on the election’s background, including a major part that required the visualization of politics in a wall newspaper. Results indicate that a singular intervention is not able to counteract disenchantment with politics in general, but to raise short-term intentions to go to the polls.

description: Graph data completion is a fundamentally important issue as data generally has a graph structure, e.g., social networks, recommendation systems, and the Internet of Things. We consider a graph where each node has a data matrix, represented as a \textit{graph-tensor} by stacking the data matrices in the third dimension. In this paper, we propose a \textit{Convolutional Graph-Tensor Net} (\textit{Conv GT-Net}) for the graph data completion problem, which uses deep neural networks to learn the general transform of graph-tensors. The experimental results on the ego-Facebook data sets show that the proposed \textit{Conv GT-Net} achieves significant improvements on both completion accuracy (50\% higher) and completion speed (3.6x $\sim$ 8.1x faster) over the existing algorithms.

description: We revisit the constraints on evaporating primordial black holes (PBHs) from the isotropic X-ray and soft gamma-ray background in the mass range $10^{16}-10^{18}$ g. We find that they are stronger than usually inferred due to two neglected effects: i) The contribution of the annihilation radiation due to positrons emitted in the evaporation process. ii) The high-latitude, Galactic contribution to the measured isotropic flux. We study the dependence of the bounds from the datasets used, the positron annihilation conditions, and the inclusion of the astrophysical background. We push the exclusion limit for non-spinning PBH with monochromatic mass function as the totality of dark matter to 1.5$\times 10^{17}\,$g, which represents a $\sim$15$\%$ improvement with respect to earlier bounds and translates into almost an order of magnitude improvement in the PBH fraction in the already probed region. We also show that the inclusion of spin and/or an extended, log-normal mass function lead to tighter bounds. Our study suggests that the isotropic flux is an extremely promising target for future missions in improving the sensitivity to PBHs as candidates for dark matter.

description: The paper aims at investigating the effect of number of story on different structural components of reinforced concrete building due to gravity and lateral loading. For the study, three building models having same building plan of three, six and nine stories are analyzed and designed using software package. All the buildings are residential and are located in Dhaka city of Bangladesh. Lateral load including wind and earthquake loading are applied to the building along both longitudinal and transverse direction as per Bangladesh National Building Code (BNBC, 2006). Equivalent static force method is followed for the applied seismic loading. The present study investigates as well as compares mainly total steel requirement in different structural components for those buildings. It has been found that total longitudinal steel requirement for beams at each floor is 48.57% for three storied building, 61.36% for six storied building when the total percentage is taken as 100% in case of nine storied building. For an exterior column, the steel ratio is 2.1%, 3.06%, 4.55% for three, six and nine storied building respectively for the first three floors. In addition, it has been noted that total weight of longitudinal reinforcement of an interior column is 14.02 % for three-storied building and 43.12% for six storied building when the total reinforcement is considered 100% for nine storied building for the first three floors.

Specifically, we investigate $\inf_X \mathrm{trace}(DX^H AX)$ subject to $X^H BX=I_k$ or $J_k=\mathrm{diag}(\pm 1)$. We establish conditions under which the infimum is finite and when it is finite, analytic solutions are obtained in terms of the eigenvalues and eigenvectors of the matrix pencil $A-λB$, where $B$ is possibly indefinite and singular, and $D$ is also possibly indefinite.

We discuss the uncertainty in the results, that is related to the determination of the string tension ($K_{F}$), appearing in the confining propagator, and the effective gluon mass ($m_{g}$) at large $n_{f}$.

Errors In Luminous Intensity Measurements And Photometric Performance Of Linear Sources Due To The Length Of The Measuring Distance.
Creators: name: Frost, J
Publisher: name: London South Bank University
Year: 1985

description: The previous published work in the area of this investigation was completed in 1963 by W Riggs and A Lampert. At that time the main consider was the effect of short distance photometry on efficiency and utilization factors. Since that time other considerations have been introduced into lighting design and the optical control in luminaires has altered significantly. This report considers the requirements for the accurate photometry of linear luminaires equipped with low pressure mercury vapor fluorescent lamps, the design requirements of an intensity distribution photometer, and the effects of errors in the mechanical and optical systems of the photometer. A unique design of variable Light path intensity distribution photometer: vertical angle indicating system have been developed, constructed, and commissioned, and the photometer has been used to measure the intensity distribution of eight types of twins {500mm tubular fluorescent lamp luminaires and the measurements have been performed at both 2.9m and 7.9m. The output of the detector of a photometer is proportional to the flux falling on the cell. The cell output must be converted, using an appropriate calibration factor, to an intensity value. Two methods of calibration have been examined and the photometric data produced using both methods have been compared. A number of computer programmes have been developed to enable the intensity distributions at the above distances to be compared and the complete photometric data for the luminaires to be calculated and the effect of using a short photometric distance evaluated. The effects of the application of the photometric data, which has been derived from both the long and short distance photometry, to the design of lighting installation have been compared for room size from 4m x 4m to lighting installations have been compared for room. 2Um x 20m. The effects of the use of the short distance intensity measurements on the by 5 parallel and perpendicular plane aspect factors and direct illuminance calculations have also been considered. From the measurements and subsequent comparisons of the calculated s installation design data the general conclusion is that the photometry at a 4 photometric distance: luminaire length ratio of 2:1 will produce reliable and acceptable lighting design data and that lighting designs produced sing this data will be virtually identical to those designed using data produced at a 5:1 ratio.

description: A sound understanding of research paradigms is crucial for developing coherent and philosophically grounded research designs, particularly in the humanities and social sciences. This paper offers an accessible overview of six key research paradigms: positivism, post-positivism, constructivism, interpretivism, pragmatism, and critical realism. These paradigms differ in their approaches to ontology (the nature of reality), epistemology (the nature of knowledge), and axiology (the role of values in research). The paper also discusses the ethical implications of these paradigms, particularly in relation to the researcher’s role in the co-construction of knowledge. Reflexivity and ethical responsibility are emphasised, where researchers must account for how their own biases and values influence their work. By exploring these paradigms and their philosophical foundations, this paper aims to help researchers identify the paradigm that best aligns with their views about the world, ultimately enabling them to design studies that are methodologically sound, ethically informed, and practically relevant. This article contributes to the academic discourse by offering a clear and practical guide to research paradigms, fostering a deeper understanding of the philosophical underpinnings that shape research practices across disciplines.

description: The success of the current generation of Noisy Intermediate-Scale Quantum (NISQ) hardware shows that quantum hardware may be able to tackle complex problems even without error correction. One outstanding issue is that of coherent errors arising from the increased complexity of these devices. These errors can accumulate through a circuit, making their impact on algorithms hard to predict and mitigate. Iterative algorithms like Quantum Imaginary Time Evolution are susceptible to these errors. This article presents the combination of both noise tailoring using Randomized Compiling and error mitigation with a purification. We also show that Cycle Benchmarking gives an estimate of the reliability of the purification. We apply this method to the Quantum Imaginary Time Evolution of a Transverse Field Ising Model and report an energy estimation and a ground state infidelity both below 1\%. Our methodology is general and can be used for other algorithms and platforms. We show how combining noise tailoring and error mitigation will push forward the performance of NISQ devices.

description: We investigate the effect of the interlayer spin-flip tunneling for the interlayer magnetoresistance under magnetic fields in alpha-(BEDT-TTF)2I3, which is a multilayer massless Dirac fermion system under pressure. The mean field of the spin-flip correlation associated with the interlayer Coulomb interaction enables the interlayer spin-flip tunneling. Assuming the non-vertical interlayer spin-flip tunneling, we calculate the interlayer magnetoresistance using the Kubo formula. The crossover magnetic field, at which the interlayer magnetoresistance changes from positive to negative is shifted by the Zeeman energy and in good agreement with the experiment.
Pleasure and Politics. Making Youth-Cultural Commitment Visible

description: Youth and politics as well as pleasure and politics are often seen as bad matches. Accordingly, today’s youth is diagnosed as generally indifferent towards politics. We suggest, that politics in youth cultures can only be made visible by looking at it from a different angle: from the perspective of reconcilability between work, politics and pleasure. This article provides and discusses a theoretical framework for the analysis of the connections between them in youth cultural contexts. Increasing medialisation and globalisation make cultural symbols accessible to almost everyone. This results in a “devaluation” of style as a marker of distinction and self-positioning. We argue that this devaluation of style causes a shift of focus onto ostensibly non-stylistic aspects in youth cultures – i.e. onto commitment, work or politics. Youth cultures can therefore be viewed as contexts in which self-professionalisation, self-education and self-socialisation take place. Even though within the field of youth culture research, youth-cultural activities are therefore no longer considered to be merely recreational activities or pastimes, youth cultural participation still means the pleasure of sharing certain cultural activities and, beyond this, the pleasure of resistance. We suggest that understanding the – in some ways unexpected und partly still unexplored – connections young people establish between work, politics and pleasure provides insight into new forms of their political commitment.

description: In a famous quote Marx said: “Hegel remarks somewhere that all great world-historic facts and personages appear, so to speak, twice. He forgot to add: the first time as tragedy, the second time as farce.” Today one would like to add, that film, television and computer games alter the historic event through modern visualizations of the past. Not only the historic facts and personages appear more than once, but also the representation of history multiplies itself in visual reconstructions, re-enactments and simulations in the media. What happens to history and its epistemology when it becomes an audiovisual experience? What are the different visual modes of knowledge production in historiography? Which uses of history become part of popular media culture? These questions are the starting point for an analysis of current examples of 'histotainment' and theoretical considerations about popular historiography.

Adolescents and Politics – A Match Made in the Media? On the Role of Entertainment-Education for Political Information
Creators: name: Arendt, Kathleen
Publisher: name: JSSE - Journal of Social Science Education
Year: 2009

description: The role of politics in the life of adolescents is a topic intensely discussed in different fields of academia – usually claiming a lack of interest in political issues among youth. State-of-the-art research is shifting to assessing the role of entertaining media content in this process reflect­ing on the changing depictions of the political along the lines of infotainment and political en­ter­tainment. This article focuses on the latter and discusses the question, how elements of politics are or could be displayed in entertaining, narrative formats, and how this could affect knowledge, attitudes and behavior. The line of argumentation is based on the conceptual­ization of Entertainment-Education (EE) as a form of strategic communication. EE describes the intentional design and implementation of a media message into entertaining narrative content based on social cognitive theory and the assumption of vicarious learning by observ­ing role modeled behavior. The article discusses findings from EE interventions outside politics and links them to the issue of youth and politics.

description: Since the discovery of superconductivity in MgB2 (Tc ~ 39 K), the search for superconductivity in related materials with similar structures or ingredients has never stopped. Although about 100 binary borides have been explored, only few of them show superconductivity with relatively low Tc. In this work, we report the discovery of superconductivity up to 32 K in MoB2 under pressure which is the highest Tc in transition-metal borides. Although the Tc can be well explained by theoretical calculations in the framework of electron-phonon coupling, the d-electrons and phonon modes of transition metal Mo atoms play utterly important roles in the emergence of superconductivity in MoB2, distinctly different from the case of well-known MgB2. Our study sheds light on the exploration of high-Tc superconductors in transition metal borides.

Civic Education with The Simpsons

description: Impudent, disrespectful and packed with slapstick comedy – this is the most prominent and most controversial cartoon family in TV history: The Simpsons. Critics complain about the decay of manners and the offensive humor of the show. There is considerable potential for civic education in the yellow universe of The Simpsons, however. On the basis of three Simpsons-episodes this article analyzes the depiction of elections and electoral races in a media democracy. This analysis aims at extracting critical positions from the satiric presentation of debates, media events and political rhetoric and connecting them to real campaigns in Germany and the USA. The examples are supposed to illustrate that The Simpsons do provide critical access to understanding campaigns in media societies – despite all satiric exaggeration of real events. Furthermore, the article shows that the series does not only comment critically on almost any event of social relevance, but also, more importantly, how we can make these comments work in civic education.

description: Des études s’accordent à dire que l’utilisation de la vidéo comme moyen didactique semble affecter positivement l’apprentissage des élèves. C’est à partir de ce constat que nous avons décidé de créer un dispositif d’enseignement vidéo, dans lequel nous développons un résumé des concepts centraux du droit des successions suisse. La vidéo dure 5 minutes et utilise le soutien d’illustrations évoluant au gré des explications. Le but du dispositif est d’avoir l’attention des élèves pour leur présenter synoptiquement la matière. Des éléments comme la durée, la quantité de contenu ou encore le rythme ont été au centre du développement de la vidéo. Ce dispositif est destiné à des élèves de deuxième année d’école de commerce et a été initialement pensé pour être utilisé en fin de séquence. La vidéo peut être trouvée sous le lien suivant : Draw my Law - Droit des successions (https://www.youtube.com/watch?v=xg5duKWsE-M) Le dispositif a été ensuite testé en classe et a reçu un accueil positif de la part des élèves. Sa principale force semble être sa capacité à rendre les élèves attentifs et à donner rapidement une vue d’ensemble du droit des successions. Sa plus grande limite semble être le rythme très élevé, particulièrement en fin de vidéo, que quelques élèves ont dit avoir eu du mal à suivre. Cette limite peut toutefois être surmontée en utilisant ce dispositif comme outil de travail à la maison, que ce soit pour réviser librement la matière ou à titre de devoir.

description: The global reform of the EU migration policy envisaged in the New Pact on Migration and Asylum is stalling. The increased number of arrivals from Belarus gave the European Commission the opportunity to change its approach in attempting to reform the European migration management. The Belarus crisis, influenced by the active involvement of the Belarus regime in facilitating third country nationals' passage towards the EU external border, has been labelled an "instrumentalisation situation" posing a threat to the security of the Union. This Insight claims that the Commission is exploit-ing the instrumentalisation narrative to push forward its agenda on migration policy, normalising the use of detention and border procedures as standard migration management tools. Such policy objectives, already introduced in 2015 with the hotspot approach, already play a key role in the overall structure of the New Pact on Migration and Asylum. The Insight argues that the Commission's fight against the instrumentalisation of migrants is in itself an instrumentalisation exercise: migrants are instrumentalised to strengthen the securitarian approach to migration; migration crises are instrumentalised to push forward sectorial elements of the New Pact; EU law is instrumentalised to intro-duce derogatory regimes as permanent components of the EU migration policy.
Probing Majorana-like states in quantum dots and quantum rings

description: Engineering chiral $p$-wave superconductivity in semiconductor structures offers fascinating ways to obtain and study Majorana modes in a condensed matter context. Here, we theoretically investigate chiral $p$-wave superconductivity in quantum dots and quantum rings. Using both analytical as well as numerical methods, we calculate the quasiparticle excitation spectra in these structures and the corresponding excitation amplitudes and charge densities. In the topological regime, we can observe the chiral edge modes localized at the boundaries and possessing finite energy in quantum dots and quantum rings. By applying a magnetic field which is expelled from the quantum ring, but which creates a flux that is an odd integer multiple of $Φ_0/2=π\hbar/e$, Majorana modes, that is, (approximately) degenerate edge modes with zero energy and zero charge density, become possible in the topological regime. Furthermore, we investigate finite-size effects that split these degenerate edge modes as well as the effect of a magnetic field penetrating into the superconducting region that can under certain circumstances still support edge modes with approximately zero energy and charge.

Quasi-plurisubharmonic envelopes 2: Bounds on Monge-Ampère volumes

description: In \cite{GL21a} we have developed a new approach to $L^{\infty}$-a priori estimates for degenerate complex Monge-Ampère equations, when the reference form is closed. This simplifying assumption was used to ensure the constancy of the volumes of Monge-Ampère measures. We study here the way these volumes stay away from zero and infinity when the reference form is no longer closed. We establish a transcendental version of the Grauert-Riemenschneider conjecture, partially answering conjectures of Demailly-Păun \cite{DP04} and Boucksom-Demailly-Păun-Peternell \cite{BDPP13}. Our approach relies on a fine use of quasi-plurisubharmonic envelopes. The results obtained here will be used in \cite{GL21b} for solving degenerate complex Monge-Ampère equations on compact Hermitian varieties.
Coming of Age at Bullworth Academy: Bully and Narratives of Youth Violence
Creators: name: Rauch, Peter

description: The 1999 rampage at Columbine High School, and the high-profile school shootings that preceded it, dramatically heightened pre-existing cultural anxieties about the consumption of violent media in childhood. In particular, videogames received unprecedented public scrutiny, and even now the spectre of Columbine continues to hang over any discussion of violent videogames. When Rockstar Games, developer of the ultraviolent Grand Theft Auto series, announced Bully, a similarly styled game that would take place in a school, controversy predictably ensued. Rockstar made no effort to dispel this controversy, and might have actually encouraged it, but the game itself bears little relation to an archetypal school shooting. As a text, Bully represents a much different narrative of adolescence, one that questions the morality of adult institutions and problematizes the very idea of “growing up.” This essay compares and contrasts Bully with other narratives of youth violence, ranging from the popularly accepted telling of the Columbine shootings to William Golding’s Lord of the Flies.
