description: The transmission dynamics of infectious diseases cannot be fully understood based on recorded case data alone. Instead, epidemics represent a complex socioecological phenomenon that is shaped by pathogen, host, and environmental characteristics and their interactions. This is particularly true for zoonotic infectious diseases, including vector-borne diseases. ‘Digital twins’ can provide valuable insight to better understand such complex systems, and further allow for experimental epidemic and "what-if" scenarios that may not be implementable in real-world settings. Using the case of the mosquito-borne dengue virus, which is expanding globally including in sub-Saharan Africa, an agent-based modeling approach was designed that aims to explore the spatiotemporal evolution of the 2019 dengue virus outbreak in urban Dar es Salaam in Tanzania, East Africa. The framework represents the characteristics and interactions of humans and mosquitoes using digital agents in a synthetic urban environment, and incorporates a traditional mathematical SEIR (Susceptible, Exposed, Infectious, Recovered) model to account for inter- and intra-host dynamics influenced by contextual factors such as local weather events. Questions in epidemiology, implementation research, and public health are outlined that can be explored using multiagent systems. In addition, useful data sources available for Tanzania are presented that informed the simulation framework.

description: Ensembles of randomized decision trees, usually referred to as random forests, are widely used for classification and regression tasks in machine learning and statistics. Random forests achieve competitive predictive performance and are computationally efficient to train and test, making them excellent candidates for real-world prediction tasks. The most popular random forest variants (such as Breiman's random forest and extremely randomized trees) operate on batches of training data. Online methods are now in greater demand. Existing online random forests, however, require more training data than their batch counterpart to achieve comparable predictive performance. In this work, we use Mondrian processes (Roy and Teh, 2009) to construct ensembles of random decision trees we call Mondrian forests. Mondrian forests can be grown in an incremental/online fashion and remarkably, the distribution of online Mondrian forests is the same as that of batch Mondrian forests. Mondrian forests achieve competitive predictive performance comparable with existing online random forests and periodically re-trained batch random forests, while being more than an order of magnitude faster, thus representing a better computation vs accuracy tradeoff.

description: Existing 3D-from-2D generators are typically designed for well-curated single-category datasets, where all the objects have (approximately) the same scale, 3D location, and orientation, and the camera always points to the center of the scene. This makes them inapplicable to diverse, in-the-wild datasets of non-alignable scenes rendered from arbitrary camera poses. In this work, we develop a 3D generator with Generic Priors (3DGP): a 3D synthesis framework with more general assumptions about the training data, and show that it scales to very challenging datasets, like ImageNet. Our model is based on three new ideas. First, we incorporate an inaccurate off-the-shelf depth estimator into 3D GAN training via a special depth adaptation module to handle the imprecision. Then, we create a flexible camera model and a regularization strategy for it to learn its distribution parameters during training. Finally, we extend the recent ideas of transferring knowledge from pre-trained classifiers into GANs for patch-wise trained models by employing a simple distillation-based technique on top of the discriminator. It achieves more stable training than the existing methods and speeds up the convergence by at least 40%. We explore our model on four datasets: SDIP Dogs 256x256, SDIP Elephants 256x256, LSUN Horses 256x256, and ImageNet 256x256, and demonstrate that 3DGP outperforms the recent state-of-the-art in terms of both texture and geometry quality.

description: Rudolf Engelhard presents a lesson model in his article How to Deal with Party Politics at School? that dates back to the 1960s, when civic education was revived in the Federal Republic of Germany (West-Germany). In order to improve civic education at school, the former Ministers of Education of German states reached a joint decision on the new subject. This was as a reaction against the first massive scribbling of Nazi propaganda since the end of World War II. Therefore, a new subject in secondary education was introduced to serve this purpose. This subject was called Sozialkunde1 (civic education) or Gemeinschaftskunde2 (social studies).

description: We present the results of the stellar feedback from Pop III binaries by employing improved, more realistic Pop III evolutionary stellar models. To facilitate a meaningful comparison, we consider a fixed mass of 60 solar masses (Msun) incorporated in Pop III stars, either contained in a single star, or split up in binary stars of 30 Msun each or an asymmetric case of one 45 Msun and one 15 Msun star. Whereas the sizes of the resulting HII regions are comparable across all cases, the HeIII regions around binary stars are significantly smaller than that of the single star. Consequently, the He$^{+}$ 1640 angstrom recombination line is expected to become much weaker. Supernova feedback exhibits great variety due to the uncertainty in possible explosion pathways. If at least one of the component stars dies as a hypernova about ten times more energetic than conventional core-collapse supernovae, the gas inside the host minihalo is effectively blown out, chemically enriching the intergalactic medium (IGM) to an average metallicity of $10^{-4}-10^{-3}$ solar metallicity (Zsun), out to $\sim 2$ kpc. The single star, however, is more likely to collapse into a black hole, accompanied by at most very weak explosions. The effectiveness of early chemical enrichment would thus be significantly reduced, in difference from the lower mass binary stars, where at least one component is likely to contribute to heavy element production and dispersal. Important new feedback physics is also introduced if close binaries can form high-mass x-ray binaries, leading to the pre-heating and -ionization of the IGM beyond the extent of the stellar HII regions.

Political Perspectives in the Classroom. Results of Video Analyses in History and Civic Education

description: Civic education is not taught as a separate subject at Swiss schools. In this context, it is of great interest to look for specific characteristics of how civic education can be observed as a cross-disciplinary subject in schools through video recordings. The empirical analysis is based on classroom observation in ninth grade classes in various Swiss cantons (Aargau, Bern, and Zurich) from 2003 to 2007. Criteria that allow the identification of elements of civic education in various school subjects are developed, the concept of “political perspective”. The analysis provides useful hints for planning and running classes where civic education is used as an overarching, cross-disciplinary approach. The concept of “political perspective” should not be taken as substitute for institutional knowledge. But the concept can rise above the function of an analytical tool and become a tool that serves the planning and designing of lessons. The perspective could as such be related to the postulate for epistemological knowledge.

description: Purpose- The study aims to investigate the impact of cloud computing, embracing Cloud Computing Service Models (Infrastructure as a Service, Platform as a Service, and Software as a Service) as theoretical lenses and testing COVID-19 as the moderator. Design/Methodology/Approach- The study was conducted based on the deductive approach and adopted a stratified random sampling which consisted of 384 IT employees among those who had experience in using Cloud Computing during the Work from Home (WFH) period. The study utilized multiple regression to find the effect of the Cloud Computing Service model and measure the Covid-19 moderation effect between Cloud Computing and WFH according to the Andrew F. Hayes method. Practical Implications- Organizations should encourage employees to use cloud computing services while working from home. The outbreak of COVID-19 shows how effective usage of cloud computing services is in working from home. If organizations implement positive policies to encourage the usage of cloud computing, it will enhance the productivity of the organizations. Social Implication- The social implications will be helpful for organizations and for users to understand the importance of cloud computing adoption and how to overcome the challenges of COVID-19. By offering online services, society can avoid direct contact and minimize the spread of COVID-19 throughout Sri Lanka. Findings- The proposed research study found that there is a positive relationship between cloud computing service models on WFH with the moderator effect of COVID-19. Originality/Value- The study set light on the SaaS as the primary contributor of the cloud computing service models and revealed that COVID-19 is the moderator for adopting Cloud Computing Services models in the WFH environment.

description: Given a virtual knot $K$, we construct a group $VG_K$ called the virtual knot group, and we use the elementary ideals of $VG_K$ to define invariants of $K$ called the virtual Alexander invariants. For instance, associated to the $k=0$ ideal is a polynomial $H_K(s,t,q)$ in three variables which we call the virtual Alexander polynomial, and we show that it is closely related to the generalized Alexander polynomial $G_K(s,t)$ introduced by Sawollek, Kauffman-Radford, and Silver-Williams. We define a natural normalization of the virtual Alexander polynomial and show it satisfies a skein formula. We also introduce the twisted virtual Alexander polynomial associated to a virtual knot $K$ and a representation $\varrho \colon VG_K \to GL_n(R)$, and we define a normalization of the twisted virtual Alexander polynomial. As applications we derive bounds on the virtual crossing numbers of virtual knots from the virtual Alexander polynomial and twisted virtual Alexander polynomial.

Two Kinds of Political Awakening in the Civic Education Classroom. A Comparative Argumentation Analysis of the “Constitutional Debates” of Two “Found-a-Village” Projects with 8th Graders
Creators: name: Petrik, Andreas
Publisher: name: JSSE - Journal of Social Science Education

description: This article proposes an adaption of the Toulmin model of argumentation as a congenial method to investigate interactive political learning processes. The interactive learning environment is provided by the “Found-a-Village” project, where students simulate to establish their own social and political system. I will start my essay by introducing the “genetic” village-setting which works as a trigger for the formation of political judgment and conflict resolution skills. Then, I will define claims, grounds, warrants and premises as basic parts of Toulmin’s model. After presenting six types of politically relevant warrants, I will present a four-level-model for the analysis of political learning processes, distinguishing private, public, institutional and systemic perspectives on politics. Later on, I apply this model by comparing two quite different classes during the initial phase of their village-projects: While the “public” class uses the simulation to seriously negotiate their political values, the second class takes a fairly playful and “private” time-out from typical instruction. Both classes, at a different speed, undergo a continual development from unfounded claims and inadequate arguments to the reflection of their own and opposed political value-orientations. The analysis of implicit parts of individual argumentation confirms the method to be helpful for teachers’ diagnosis skills.

Challenges of Social Science Literacy
Creators: name: Weber, Birgit
Publisher: name: JSSE - Journal of Social Science Education
Year: 2010

description: Since international tests compare the performance of students in different subjects, the issue of literacy in the social science subject is becoming more pressing. The successes and failures in international tests influence the national education policies considerably. First, the inclusion of subjects in international comparisons has consequences for their importance. Second, the race in the Olympics of education leads to an increasing focus on the output of educational processes, also measured in the central exams. Social Sciences can refuse to take part in the national comparison studies with the price of losing much more importance; they can participate with the danger of undermining their goals. This raises a lot of questions: What competences students need in this social world to reason about it und to act responsibly? What is the foundation of concepts from social science students need for guidance and understanding their place and role as an individual in society? The social science disciplines, as sociology, political science and economics in a narrow sense, history, law and geography in a broader sense, supported by philosophy, pedagogy and psychology are able to select them for educational purposes or determine such educational aims. This Journal wants to resume und discuss competences and core con¬cepts for political and economic teaching and learning as Social Science Literacy”. Contributions in this issue do not only discuss and recommend competences and core concepts from a domain specific political or economic point of view, but also from an interdisciplinary or psychological point of view. They analyse preconditions and interdependencies as well as obstacles und problems of development and diagnosis core concepts and competences of Social Science Literacy.

description: Time-reversal symmetry prohibits elastic backscattering of electrons propagating within a helical edge of a two-dimensional topological insulator. However, small band gaps in these systems make them sensitive to doping disorder, which may lead to the formation of electron and hole puddles. Such a puddle -- a quantum dot -- tunnel-coupled to the edge may significantly enhance the inelastic backscattering rate, due to the long dwelling time of an electron in the dot. The added resistance is especially strong for dots carrying an odd number of electrons, due to the Kondo effect. For the same reason, the temperature dependence of the added resistance becomes rather weak. We present a detailed theory of the quantum dot effect on the helical edge resistance. It allows us to make specific predictions for possible future experiments with artificially prepared dots in topological insulators. It also provides a qualitative explanation of the resistance fluctuations observed in short HgTe quantum wells. In addition to the single-dot theory, we develop a statistical description of the helical edge resistivity introduced by random charge puddles in a long heterostructure carrying helical edge states. The presence of charge puddles in long samples may explain the observed coexistence of a high sample resistance with the propagation of electrons along the sample edges.

description: We report two new radio detections of cataclysmic variables (CVs), and place them in context with radio and X-ray detections of other CVs. We detected QS Vir, a low accretion-rate CV; V2400 Oph, a diskless intermediate polar (IP); and recovered the polar AM Her in the Very Large Array Sky Survey (VLASS) 2-4 GHz radio images. The radio luminosities of these systems are higher than typically expected from coronal emission from stars of similar spectral types, and neither system is expected to produce jets, leaving the origin of the radio emission a puzzle. The radio emission mechanism for these two CVs may be electron-cyclotron maser emission, synchrotron radiation, or a more exotic process. We compile published radio detections of CVs, and X-ray measurements of these CVs, to illustrate their locations in the radio - X-ray luminosity plane, a diagnostic tool often used for X-ray binaries, active galactic nuclei, and radio stars. Several radio-emitting CVs, including these two newly detected CVs, seem to lie near the principal radio/X-ray track followed by black hole X-ray binaries (BHXBs) at low luminosity, suggesting additional complexity in classifying unknown systems using their radio and X-ray luminosities alone.
The Epistemological and Didactical Challenges Involved in Teaching Socially Acute Questions. The Example of Globalization

description: Teachers are being asked to manage a specific didactic situation which falls into the category of what we have proposed to call “socially acute questions (SAQs)”. A SAQ is a question which is acute in society, in background knowledge and in knowledge taught. Thus, teaching SAQs demands socio-epistemological reflexivity in the processes of knowledge production and in the social conditions in which this knowledge emerges; teaching SAQs will give priority to interdisciplinary, scientific and ethical reasoning. The split between ideology and science can certainly be examined when considering a socially acute question which is the subject of debate in society. In the example of the globalization taught: the diversity of analysis in the economic domain gives rise to great uncertainty because it justifies practically opposing policies; within a transdisciplinary framework, the globalization includes concepts, ideologies or social practices in a double movement of standardization and differentiation. By way of SAQs, we have attempted to show that learning stakes are numerous. However didactic choices must be supported by socio-epistemological survey, the identification of an epistemological posture and the definition of a didactic strategy Les enseignants sont appelés à gérer une situation didactique spécifique dans l’enseignement des «questions socialement vives (QSV) ». Les QSV sont des questions qui donnent lieu à débat dans la société, dans les savoirs scientifiques et dans l’enseignement. Ainsi, l‘enseignement des QSV nécessite une réflexivité socio-épistémologique dans le processus de production du savoir et dans les conditions sociales d’émergence de ces savoirs; l’enseignement des QSV donnera la priorité au raisonnement interdisciplinaire, scientifique et éthique. La scission entre l‘idéologie et la science peut être examinée lors de l‘examen d‘une QSV qui fait l‘objet d‘un débat dans la société. Dans l‘exemple de l’enseignement de la mondialisation: la diversité des analyses économiques donne lieu à une grande incertitude en justifiant des politiques quasi-opposées; dans un cadre transdisciplinaire, la mondialisation recouvre des concepts, des idéologies ou des pratiques sociales dans un double mouvement d‘uniformisation et de différenciation. Nous avons tenté de montrer que les enjeux de l‘apprentissage sont nombreux dans les l’enseignement des QSV. Les choix didactiques doivent être soutenues par une enquête socio-épistémologique, l‘identification d’une posture épistémologique et la définition d‘une stratégie didactique.

description: We consider a single-level quantum dot tunnel-coupled to one normal and one superconducting lead. We employ a diagrammatic real-time approach to calculate the finite-frequency current noise for subgap transport. The noise spectrum gives direct access to the internal dynamics of the dot. In particular the noise spectrum shows sharp dips at the frequency of the coherent oscillations of Cooper pairs between dot and superconductor. This feature is most pronounced when the superconducting correlation is maximal. Furthermore, in the quantum-noise regime, $ω> k_\text{B}T,μ_\text{N}$, the noise spectrum exhibits steps at frequencies equal to the Andreev addition energies. The height of these steps is related to the effective coupling strength of the excitations. The finite-frequency noise spectrum hence provides a full spectroscopy of the system.

Two Peculiarities of Economic Education
Creators: name: Remmele, Bernd
Publisher: name: JSSE - Journal of Social Science Education
Year: 2010

description: In order to model economic competences and to draw the didactic-methodological consequences it is necessary to take into account specific conditions of the conceptual development concerning economic issues and the respective learning paths. In this respect economic education has to deal with two fundamental peculiarities. First, the concept of the market as system unintendedly coordinating a multitude of actions is not transparent in the individual action. Thus, the learning paths to this concept of market cannot just build on the concept of the market as the concrete place of economic interactions. Second, the market’s systemic coordination of feedback processes, particularly the negative ones, is rather unintuitive. Intuition prefers unidirectional linear causal relations. These two interrelated peculiarities are present in the cognitive development of economic concepts. Competence requirements have to be defined respectively and methodological choices in teaching systemic ‘phenomena’ have to reflect this constraint Um ökonomische Kompetenzmodelle zu entwickeln und daraus didaktisch-methodische Konsequenzen zu ziehen, ist es notwendig bestimmte Bedingungen der konzeptuellen Entwicklung ökonomischer Zusammenhänge sowie diesbezüglich relevante Lernwege zu berücksichtigen. In dieser Hinsicht muss sich ökonomische Bildung mit zwei Besonderheiten auseinandersetzen: Erstens, das Konzept des Marktes als System nicht-intendierter Koordination einer Vielzahl von Handlungen ist in der einzelnen Handlung nicht einsichtig. Daher kann der dieses Konzept betreffende Lernweg und entsprechende Lehrmethoden nicht einfach am Marktkonzept als konkreter Ort konkreter wirtschaftlicher Interaktionen ansetzen. Zweitens, die systemische Koordinationsleistung des Marktes in Bezug auf Rückkoppelungsprozesse, insbesondere negative Rückkoppelungen, ist relativ unanschaulich. Unsere Anschauung präferiert unidirektionale lineare kausale Verknüpfungen. Die beiden Besonderheiten stehen somit in engem Bezug zur kognitiven Entwicklung ökonomischer Konzepte. Kompetenzanforderungen und die Wahl von Lehr/Lernmethoden in Hinsicht auf systemische ‚Phänomene‘ müssen daher diese Bedingungen bedenken.

description: We formulate a phenomenological description of thin ferromagnetic layers with inversion asymmetry where the single-domain magnetic dynamics experiences magnon current-induced torques and leads to magnon-motive forces. We first construct a phenomenological theory based on irreversible thermodynamics, taking into account the symmetries of the system. Furthermore, we confirm that these effects originate from Dzyaloshinskii-Moriya interactions from the analysis based on the stochastic Landau-Lifshitz-Gilbert equation. Our phenomenological results generalize to a general form of Dzyaloshinskii-Moriya interactions and to other systems, such as pyrochlore crystals and chiral magnets. Possible applications include spin current generation, magnetization reversal and magnonic cooling.

Political Competences and Political Participation: On The Role of “Objective” Political Knowledge, Political Reasoning, and Subjective Political Competence in Early Adulthood
Creators: name: Reichert, Frank
Publisher: name: JSSE - Journal of Social Science Education
Year: 2010

description: This article deals with the relation of objective political competences and the subjective assessment of one’s own political competence. The theoretical frame states that at least in early adulthood, only the subjective competence but not political knowledge is an autonomous and important determinant for (socio-)political participation, mediating the influence of objective political competences (or political knowledge, respectively). To test the role of subjective political competence and the (remaining) effect of political knowledge in early adulthood, empirical evidence using a sample of university students is presented. Cross-sectional analyses show that political knowledge has at least, if anything, an impact on voting, while fully mediated by subjective political competence relating non-electoral legal political activities. In contrast, the more profound competence of political reasoning has clear and stable positive effects on the intention to engage in non-electoral legal political actions – here subjective competence seems to be less important. Eventually, after a short excursus on school participation the findings are summarised and discussed by relating them back to framework and hypothesis. A concluding section proposes two opposing developmental-psychological considerations about the findings, raising further questions and giving an outlook into future research.

description: We examine the structure and dynamics of small isolated $N$-particle clusters interacting via short-ranged Morse potentials. "Ideally preprared ensembles" obtained via exact enumeration studies of sticky hard sphere packings serve as reference states allowing us to identify key statistical-geometrical properties and to quantitatively characterize how nonequilibrium ensembles prepared by thermal quenches at different rates $\dot{T}$ differ from their equilibrium counterparts. Studies of equilibrium dynamics show nontrival temperature dependence: nonexponential relaxation indicates both glassy dynamics and differing stabilities of degenerate clusters with different structures. Our results should be useful for extending recent experimental studies of small colloidal clusters to examine both equilibrium relaxation dynamics at fixed $T$ and a variety of nonequilibrium phenomena.

description: For every metric space $X$ we introduce two cardinal characteristics $\mathrm{cov}^\flat(X)$ and $\mathrm{cov}^\sharp(X)$ describing the capacity of balls in $X$. We prove that these cardinal characteristics are invariant under coarse equivalence and prove that two ultrametric spaces $X,Y$ are coarsely equivalent if $\mathrm{cov}^\flat(X)=\mathrm{cov}^\sharp(X)=\mathrm{cov}^\flat(Y)=\mathrm{cov}^\sharp(Y)$. This result implies that an ultrametric space $X$ is coarsely equivalent to an isometrically homogeneous ultrametric space if and only if $\mathrm{cov}^\flat(X)=\mathrm{cov}^\sharp(X)$. Moreover, two isometrically homogeneous ultrametric spaces $X,Y$ are coarsely equivalent if and only if $\mathrm{cov}^\sharp(X)=\mathrm{cov}^\sharp(Y)$ if and only if each of these spaces coarsely embeds into the other space. This means that the coarse structure of an isometrically homogeneous ultrametric space $X$ is completely determined by the value of the cardinal $\mathrm{cov}^\sharp(X)=\mathrm{cov}^\flat(X)$.

Questionning the Citizenship Industry
Creators: name: Splitter, Laurance J.
Publisher: name: JSSE - Journal of Social Science Education
Year: 2011

description: I argue that citizenship and related concepts should be treated warily by educators and researchers. Citizenship cannot define who I am, nor can it plausibly ground moral or values education. For both these tasks, the relational concept of being a person in the world does a better, and simpler, job. I suggest that classrooms which take the concept of personhood seriously should function as inquiring communities, in which such issues as the meaning and importance of our affiliations and associations may be critically examined. There may be good reasons for the recent expansion of what I term “the citizenship industry” in educational research, but they should not be taken for granted, particularly given that the concept of citizenship is often used by governments around the world to support strongly nationalistic policies which are inimical to genuine inquiry and autonomy.

description: We propose a quantum symmetry reduction of loop quantum gravity to Bianchi I spacetimes. To this end, we choose the diagonal metric gauge for the spatial diffeomorphism constraint at the classical level, leading to an $\mathbb{R}_{\text{Bohr}}$ gauge theory, and quantise the resulting theory via loop quantum gravity methods. Constraints which lead classically to a suitable reduction are imposed at the quantum level. The dynamics of the resulting model turn out to be very simple and manifestly coincide with those of a polymer quantisation of a Bianchi I model for the simplest choice of full theory quantum states compatible with the Bianchi I reduction. In particular, the "improved" $\barμ$ dynamics of loop quantum cosmology can be obtained by modifying the regularisation of the Hamiltonian constraint with similar ideas, in turn yielding insights into the full theory dynamics.

description: With the recent advent of affordable consumer technologies like Oculus Rift and gadgets from other technology companies as HTC, Google, or Samsung, virtual reality has gained enormous popularity. Offering unique characteristics like the feeling of being in a virtual space and a natural interaction with objects in this space, virtual reality has also been part of research as a promising learning tool. However, results in this context are mixed. Using the approach of a systematic literature review, this research scrutinizes these different results and contradictory theories. The outcomes present which theoretical approaches have been taken to explain learning and which factors are essential regarding the design of a virtual space. Furthermore, this research identifies future research opportunities to better understand and unfold the potential of virtual reality for learning.
title: Saudi-Iranian proxy wars in the Middle East: Syria, Iraq, and Yemen
Creators: name: Baliqi, Edon
Year: 2022

description: Der Nahe Osten ist eine der komplexesten Regionen der Welt, in der Krieg das dominanteste Wort ist, wenn Medien aus oder über die Region berichten. Diese Masterarbeit zeigt, dass hinter den blutigsten Kriegen im Nahen Osten immer zwei Länder stecken, nämlich Saudi-Arabien und der Iran. Sie bekämpfen sich durch ihre Stellvertreter in verschiedenen Ländern gegenseitig, stehen sich dennoch nie direkt gegenüber. Diese Arbeit analysiert, wie die Rivalität zwischen den beiden größten Mächten der Region die Hauptursache für den Tod und das Leid der Menschen, sowie für die Zerstörung von Wirtschaften ist. Der Irak, Jemen und Syrien wurden als Beispiele ausgewählt, da anhand dieser Länder am besten gezeigt werden kann, wie die Stellvertreterkriege zwischen zwei regionalen Großmächten dazu genutzt wurden, um geopolitische Vorteile zu erzielen. Darüber hinaus sind auch andere Länder wie die USA oder Russland beteiligt, die die Lage negativ beeinflussten und deren Beteiligung ein Faktor für die Verlängerung der Kriege ist. Die innerstaatlichen Kriege, die durch eine internationale Beteiligung über Stellvertreter und Interventionen gekennzeichnet sind, scheinen durch religiöse, geopolitische und wirtschaftliche Gründe ausgelöst worden zu sein, die alle im Namen der hegemonialen Vormachtstellung in der Region geschehen.
description: The Middle East is one of the most complex regions in the world, where war has been the main word used when media would report from or for the region. The thesis shows that behind the bloodiest wars in the Middle East there are always two countries involved, Saudi Arabia and Iran, who fight each other through their proxies in different countries but never directly confront each other. This study aims to give a clearer picture and analyse how the rivalry between the two biggest powers of the region has been the main cause of death and suffering among the people and the destruction of economies. The countries of Iraq, Yemen, and Syria are chosen because they give the best example of how the proxy wars between two regional superpowers used them in order to gain geopolitical benefits for their own interests. Furthermore, there are also other countries involved, such as the US or Russia who had a negative impact and also are a factor in the prolongation of the wars. The intrastate wars that are characterized by international involvement via proxies and interventions seem to have been caused by religious, geopolitical, and economical reasons all happening in the name of reaching hegemony in the region.

description: The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning. Here, using scanning tunnelling spectroscopy in a weakly pinned Co0.0075NbSe2 single crystal, we show that at low temperatures, the vortex lattice in a 3-dimensional superconductor disorders in two steps across the peak effect. At the onset of the peak effect, the equilibrium Bragg glass transforms into an orientational glass through the proliferation of dislocations. At a higher field, the dislocations dissociate into isolated disclination giving rise to an amorphous vortex glass. We also show the existence of a variety of additional non-equilibrium metastable states, which can be accessed through different thermomagnetic cycling.
description: The analysis of the positional and orientational correlation functions have been refined in this version of the manuscript

description: In questo scritto parliamo di due gesuiti al servizio della corte sabauda, Emanuele Tesauro e Pierre Monod, che si scontrarono in una disputa sul segno zodiacale di Ottaviano Augusto. Tesauro diceva Vergine e Monod diceva Capricorno. Se guardiamo ai recenti studi sul tema, aveva ragione Monod. Il suo approccio basato sugli autori antichi, di cui fornisce ricca documentazione, e sugli studi a lui noti è molto interessante per chi vuol completare la panoramica sull'argomento. Monod usa anche le immagini sulle monete per avvalorare il Capricorno come ascendente di Augusto e questo lo rende un Paul Zanker del XVII secolo, alla ricerca del potere delle immagini usate dall'imperatore romano.

description: Let $X$ be a smooth, closed, connected, orientable four-manifold with $b^1(X)=0$ and $b^+(X)\geq 3$ and odd. We show that if $X$ has Seiberg-Witten simple type, then the SO(3)-monopole cobordism formula of Feehan and Leness (2002) implies Witten's Conjecture relating the Donaldson and Seiberg-Witten invariants.

description: New extensions of the KP and modified KP hierarchies with self-consistent sources are proposed. The latter provide new generalizations of $(2+1)$-dimensional integrable equations, including the DS-III equation and the $N$-wave problem. Furthermore, we recover a system that contains two types of the KP equation with self-consistent sources as special cases. Darboux and binary Darboux transformations are applied to generate solutions of the proposed hierarchies.

description: In this book Nussbaum makes a strong case for the importance of the liberal arts in education. If the economic pressure of globalization is not kept under control, the end result might be an erosion of our democracies. The book is more a manifesto (178 pages) and not an empirical study. Quantitative data have been omitted.
