description: We study how the universal contribution to entanglement entropy in a conformal field theory depends on the entangling region. We show that for a deformed sphere the variation of the universal contribution is quadratic in the deformation amplitude. We generalize these results for Rényi entropies. We obtain an explicit expression for the second order variation of entanglement entropy in the case of a deformed circle in a three dimensional CFT with a gravity dual. For the same system, we also consider an elliptic entangling region and determine numerically the entanglement entropy as a function of the aspect ratio of the ellipse. Based on these three-dimensional results and Solodukhin's formula in four dimensions, we conjecture that the sphere minimizes the universal contribution to entanglement entropy in all dimensions.

description: The objective of the study was to examine the influence of vegan stereotypes on person perception in the context of a job application. The study was conducted online on a representative sample of Polish adults (N=838). Participants evaluated a fictitious CV of a candidate applying for a job. The CV varied in three dimensions: (a) diet of the candidate (vegan or not); (b) gender of the candidate; and (c) job position (stereotypically male or female). The candidate was evaluated on the dimensions of warmth and competence (based on the stereotype content model).

description: Didaktik als Integration von Unterrichtsmethodik, Unterrichtsinhalt (Lehrplan bzw. Curriculum), Unterrichtsorganisation einerseits, der Bildungstheorie andererseits kann nach den Erfahrungen der Lehrkunstdidaktik am ehesten gelingen durch eine kasuistische Konzentration auf die Gestaltung von Lehrstücken, durch Konzentration auf die Ausgestaltung der üblichen thematisch-methodisch-organisatorisch kohärenten Unterrichtseinheiten von 10-25 Stunden, eine Ausgestaltung in drei plus eins Zügen: Erstens nimmt Lehrkunstdidaktik sich Unterrichtseinheiten zu kulturell und schulisch sowie persönlich zentralen Themen vor, zu epochenübergreifenden Menschheitsthemen. Zweitens gestaltet sie diese Unterrichtseinheiten exemplarisch-genetisch-dramaturgisch aus gemäß der lehrkunstdidaktischen Methodentrias. Drittens wird die Unterrichtsorganisation umgewandelt in Richtung kulturauthentischer Lernorte, Lernzeiten und Lernformen. Schließlich viertens: Alle Unterrichtsinhalte, Unterrichtsmethoden, Unterrichtsorganisationen müssen sich immer wieder vor dem Anspruch der Bildungsidee verantworten, müssen sich also fragen lassen, ob in dieser Unterrichtseinheit auch tatsächlich eine freie Entfaltung der Persönlichkeit in Wechselwirkung mit einer tiefgründigen Erschließung der Welt gelungen ist. Denn erst dann ist eine Unterrichtseinheit zum Lehrstück ausgestaltet. Bei dieser Ausgestaltung von Unterrichtseinheiten zu Lehrstücken sind in den letzten zwanzig Jahren auf Wagenscheins Spuren über dreißig Lehrstücke zustande gekommen. Hierbei hat sich als Arbeitsform die Kollegiale Lehrkunstwerkstatt bewährt und als Gestaltungsprodukt die kasuistische Form aufgeklärt subjektiver Unterrichtsberichte, fast "Bildungsnovellen" - und insgesamt eine Orientierung der Didaktik nicht nur an der Wissenschaft, sondern auch an den Künsten: daher Lehrkunstdidaktik: Im Schauspielführer sind viele hundert Theaterstücke beschrieben, wir träumen von einem kleinen Lehrstückführer. - Neuerdings öffnet sich die Perspektive für einen Beitrag des Lehrstückunterrichts zur schulischen Unterrichtsentwicklung.

Year: 2004

description: Lehrstücke im Lernfeld Gesellschaft/Politik - Fehlanzeige? Entlang von acht Suchstrategien in Geschichte und Konzeptionen der Fächergruppe wird nachgewiesen, daß es eine gewachsene Tradition von Unterrichtsmodellen gibt. Politische Lehrstücke liegen auf den unterschiedlichen Ebenen des Elementaren nach Klafki: Fundamentales, Exemplarisches, Typisches, Klassisches, Repräsentatives. Das Paradigma der kategorialen Konfliktdidaktik führt zu einem sachlogischen Kerncurriculum, das es Schülerinnen und Schülern ermöglicht, die werthaltigen Verfahren der Demokratie im Prozeß des Werdens zu erleben und zu reflektieren. Für diese Logik und Grammtik des Politischen gibt es drei Inszenierungsmodi. Die Weiterentwicklung vorliegender Unterrichtsmodelle sichert Qualitätsstandards und wird als mittelfristige Strategie der Curriculumreform empfohlen.

On the other hand, if the corresponding class of limits contains either pullbacks or equalizers, then the class of colimits is contained in that of pseudo-filtered colimits.

Year: 2004

description: Dieser Beitrag will dazu anregen, den Fokus politikdidaktischer Debatten von theoretischen Konzeptionen auf die Gestaltung von Lernprozessen zu lenken. Er simuliert eine Lehrkunstwerkstatt (I.1.), in der sieben Unterrichtsmodelle zum Schlüsselthema Zukunft verglichen werden (I.2.). Dabei konkretisieren sich zwei typische Probleme: austauschbare, schnell veralternde Inhalte und der Transfer zu Analyse- und Urteils-Kategorien. Das genetische Prinzip wird als mögliche Abhilfe eingeführt: Es vernetzt Kategorien zu Konzepten und sucht nach besonderen Inhalten (Exempeln), die Lernende in Entdeckungsprozesse verwickeln (I.3.). Das Konzept Zukunft (Prognose - Utopie - Planung) (I.4.) lässt sich durch fünf genetische Zugänge erschließen: von subjektiven Vorstellungen aus (II.1.), auf den Spuren wissenschaftlicher Erkenntnisse (II.2.), mit Modellen politischer Realität (II.3.), anhand historischer Politikvorstellungen und Ursprüngen sozialer Neuerungen (beide II.4.). Fazit: Das genetische Prinzip erweist sich als hilfreiches Suchinstrument für ein politisches Kerncurriculum (II.5.).

description: "Welches ist nun für die Mehrzahl der Staaten und der Menschen die beste Verfassung und die beste Lebensform, (...) indem man (...) von dem Leben (ausgeht), das die Mehrzahl zu führen vermag, und einer Verfassung, die sich die Mehrzahl der Staaten aneignen können?" (Aristoteles) Diese Frage ist bis heute die zentrale Frage der politischen Ordnung. Zur Klärung dieser Frage griff Aristoteles auf die Einteilungen in Monarchie - Oligarchie - Demokratie (Herodot) und die Analysen Platons in der "Politeia" zurück; er sichtete selbst 158 Verfassungen. Dabei stellte er zwei grundlegende Bedingungen für einen stabilen Staat für normale Menschen fest: Eine ausgewogene Sozialstruktur und Beteiligungsmöglichkeiten der verschiedenen sozialen Gruppen. Die Schüler werden über eine Simulation in die Neugründung eines Staates eingebunden. Dabei erfahren sie praktisch und erarbeiten sie theoretisch die Gefährdungen eines Staates und schaffen dabei mit den Prinzipien eines neuen Staates - teils aus eigener Kraft, teils durch Beratung durch Aristoteles - und entwerfen ein politisch-gesellschaftliches Organisationsmodell. Dabei gewinnen sie Kenntnisse, Erkenntnisse und Einsichten im Hinblick auf die Aufgaben und Schwierigkeiten einer demokratischen politischen Ordnung, die ihnen später ein vertieftes Verstehen der Ordnung nach dem GG ermöglicht.

The Reflection of a Warlike Historical Culture in the Attitudes of Finnish Youths

Publisher: name: JSSE - Journal of Social Science Education
Year: 2013

description: Two school shootings took place in Finland in 2007–2008, in which 20 people lost their lives. After the shootings, foreign journalists used the violent culture of Finnish men as an explanation for the tragedies. Of the old EU countries, the highest rate of capital crimes is found in Finland. The country has for a long time debated where the violence comes from. One explanation is that the historical culture in Finland glorifies war. The wars that were fought against the Soviet Union (1939–1944) have been elevated in Finland to become key elements of the national psyche, manifested in celebrations, anniversaries and through family narratives. According to this explanation, a Finn already learns as a child to accept violence which is considered to be legitimate and to behave in accordance with warlike ideals. This article examines the warlike historical culture in Finland and clarifies why war has remained a popular theme of Finnish historical culture. Further, it discusses the impact that a warlike historical culture has on the attitudes of young people.

Low-energy effective theory in the bulk for transport in a topological phase

description: We construct a low-energy effective action for a two-dimensional non-relativistic topological (i.e.\ gapped) phase of matter in a continuum, which completely describes all of its bulk electrical, thermal, and stress-related properties in the limit of low frequencies, long distances, and zero temperature, without assuming either Lorentz or Galilean invariance. This is done by generalizing Luttinger's approach to thermoelectric phenomena, via the introduction of a background vielbein (i.e.\ gravitational) field and spin connection a la Cartan, in addition to the electromagnetic vector potential, in the action for the microscopic degrees of freedom (the matter fields). Crucially, the geometry of spacetime is allowed to have timelike and spacelike torsion. These background fields make all natural invariances--- under U(1) gauge transformations, translations in both space and time, and spatial rotations---appear locally, and corresponding conserved currents and the stress tensor can be obtained, which obey natural continuity equations. On integrating out the matter fields, we derive the most general form of a local bulk induced action to first order in derivatives of the background fields, from which thermodynamic and transport properties can be obtained. We show that the gapped bulk cannot contribute to low-temperature thermoelectric transport other than the ordinary Hall conductivity; the other thermoelectric effects (if they occur) are thus purely edge effects. The coupling to "reduced" spacelike torsion is found to be absent in minimally-coupled models, and using a generalized Belinfante stress tensor, the stress response to time-dependent vielbeins (i.e.\ strains) is the Hall viscosity, which is robust against perturbations and related to the spin current as in earlier work.

subject: Psycholinguistics (incl. speech production and comprehension)

description: Language breakdown after stroke has been extensively studied in the aphasiology literature. However, strokes are diffuse lesions and can result in cognitive impairments beyond language, in domains such as attention, executive functions, memory and visuospatial deficits. Recent research has focused on cognitive abilities in aphasia and how they relate to linguistic impairment. Moreover, the accurate assessment of cognition is important for a variety of reasons, including to determine the extent of cognitive deficits beyond language and for rehabilitation planning. This thesis aimed to examine the relationship between semantic processing and cognition in aphasia, as well as to discuss current cognitive assessment practices in aphasia. A variety of methods were used to investigate these issues: a critical and a systematic review, an experimental study and a survey.Following an introductory overview (Chapter 1), two chapters focus on the relationship between semantic processing and executive control in aphasia. Chapter 2 examines the role of cognitive abilities in semantic processing tasks and presents a critical review of the Controlled Semantic Cognition account. Chapter 3 tests the prediction from the Controlled Semantic Cognition account that associative errors in naming tasks are a consequence of semantic control deficits and which other factors may influence the occurrence of associative errors.The next two chapters focus on practices regarding the assessment of cognition in aphasia. Chapter 4 presents a systematic appraisal of the tools used to assess cognition in studies with aphasia published from 2010 to 2020. Chapter 5 explores aphasia clinicians’ and researchers’ views on the current practices of assessment of cognition in aphasia. Finally, in Chapter 6, the main results are discussed considering their contribution to our current understanding of the relationship between cognition and language in aphasia.Overall, this thesis presents results that underscore the importance of accurately assessing cognition in aphasia and provides an overview of assessment practices in the research and clinical context. In addition, it contributes to the knowledge of semantic processing in aphasia and how it relates to cognitive processing.

description: La medicina tradicional asiática considera los defectos congénitos como irregularidades del Jing. La asociación estrecha del Ming Men con los Riñones (Zang), supone que éstos, a través de su sistema vaso primo de canales y colaterales, son los encargados de distribuir el Jing a los diferentes Zang-Fu. Una alteración defectuosa de la embriogénesis de las ramas del meridiano principal del Riñón pudiera ser la causa de síndromes congénitos, según los mecanismos para el desarrollo de malformaciones cardiovasculares resumidas por Clark, como la Comunicación interauricular (CIA), asociada a las anomalías del Flujo Hemático Intracardiaco Derecho, los de la Matriz Extracelular con defectos del Cojinete Endocárdico y los del Crecimiento Direccional Anómalo . Este trabajo pretendió identificar situaciones bioeléctricas anómalas en el seguimiento evolutivo de pacientes operados de CIA y brindar una interpretación de los Zang-Fu y canales comprometidos. Los resultados de la aplicación del Sistema Automatizado de la Acupuntura permitieron, en los pacientes operados de CIA, detectar un grupo de Zang-Fu afectados que, dentro de la fisiología de la medicina tradicional asiática, forman parte de los elementos claves en la formación del Qí nutricional, pero muy en particular, en este estudio, se pudo perfilar que los Zang Fu afectados que destacaban en los parámetros medidos, son casi todos los involucrados en el funcionamiento del San Jiao de estos pacientes durante su rehabilitación postquirúrgica con procederes de la medicina bioenergética y naturalista.

description: Electroweak Baryogenesis (EWBG) is a compelling scenario for explaining the matter-antimatter asymmetry in the universe. Its connection to the electroweak phase transition makes it inherently testable. However, completely excluding this scenario can seem difficult in practice, due to the sheer number of proposed models. We investigate the possibility of postulating a "no-lose" theorem for testing EWBG in future e+e- or hadron colliders. As a first step we focus on a factorized picture of EWBG which separates the sources of a stronger phase transition from those that provide new sources of CP violation. We then construct a "nightmare scenario" that generates a strong first-order phase transition as required by EWBG, but is very difficult to test experimentally. We show that a 100 TeV hadron collider is both necessary and possibly sufficient for testing the parameter space of the nightmare scenario that is consistent with EWBG.

description: Problem: Breastfeeding has many important benefits for both mother and baby but sustained breastfeeding is sub-optimal. Background: Identifying women who need increased support to establish breastfeeding has the potential to improve this. Analysis of the relationship between primary postpartum haemorrhage (PPH) and primary severe PPH and breastfeeding may prove informative as PPH has potentially negative impacts on breastfeeding. Aim: To determine the relationship between PPH and severe PPH and breastfeeding at postnatal discharge and formula use for breastfed babies in hospital. Methods: Population-based retrospective cohort study using the Victorian Perinatal Data Collection for all liveborn singleton births at ≥ 37 weeks’ gestation (n = 339,854) for 2009–13 in Victoria. Estimated blood loss was categorised as PPH ≥ 500 mL and severe PPH ≥ 1500 mL. Descriptive analysis was conducted and multivariable logistic regression was used to determine the adjusted odds ratio for the relationship between PPH/severe PPH and breastfeeding outcomes after adjustment for relevant confounders. Findings: Overall, 94.9% of women initiated breastfeeding. Babies whose mother had a PPH or severe PPH were less likely than others to be exclusively breastfeeding at discharge (aOR 0.88; (95% CI 0.86, 0.90) and aOR 0.57; (95% CI 0.53, 0.61) respectively). Formula – given to 25.9% of all breastfed babies – was more likely for those whose mothers had a PPH or severe PPH (aOR 1.15; (95% CI 1.12, 1.17) and aOR 2.15; (95% CI 2.01, 2.29) respectively. Conclusions: Women have greater challenges establishing exclusive breastfeeding following PPH and severe PPH. Improving support in hospital for women following PPH may increase breastfeeding success.

description: This paper proposes an efficient method based on the steered-response power (SRP) technique for sound source localization using microphone arrays: the volumetric SRP (V-SRP). As compared to the SRP, by deploying a sparser volumetric grid, the V-SRP achieves a significant reduction of the computational complexity without sacrificing the accuracy of the location estimates. By appending a fine search step to the V-SRP, its refined version (RV-SRP) improves on the compromise between complexity and accuracy. Experiments conducted in both simulated- and real-data scenarios demonstrate the benefits of the proposed approaches. Specifically, the RV-SRP is shown to outperform the SRP in accuracy at a computational cost of about ten times lower.

Parallel Algorithms for Constrained Tensor Factorization via the Alternating Direction Method of Multipliers

description: Tensor factorization has proven useful in a wide range of applications, from sensor array processing to communications, speech and audio signal processing, and machine learning. With few recent exceptions, all tensor factorization algorithms were originally developed for centralized, in-memory computation on a single machine; and the few that break away from this mold do not easily incorporate practically important constraints, such as nonnegativity. A new constrained tensor factorization framework is proposed in this paper, building upon the Alternating Direction method of Multipliers (ADMoM). It is shown that this simplifies computations, bypassing the need to solve constrained optimization problems in each iteration; and it naturally leads to distributed algorithms suitable for parallel implementation on regular high-performance computing (e.g., mesh) architectures. This opens the door for many emerging big data-enabled applications. The methodology is exemplified using nonnegativity as a baseline constraint, but the proposed framework can more-or-less readily incorporate many other types of constraints. Numerical experiments are very encouraging, indicating that the ADMoM-based nonnegative tensor factorization (NTF) has high potential as an alternative to state-of-the-art approaches.

Creators: name: Schirwani, Hardy
Year: 2022

description: Die Geschichte des Irak ist mit sehr vielen umfassenden Veränderungsdynamiken verbunden. Es galt insbesondere in den letzten Jahren darum, zentralistische Staatsformen in ein demokratisches System zu organisieren. Gleichzeitig bildeten sich bereits im Laufe des 20. Jahrhunderts prädemokratische Formen und Elemente eines kaum regulierten kapitalistischen Systems aus. Unter diesen Vorzeichen und hinsichtlich einer spannungsgeladenen Zeit mit zahlreichen innen- und außenpolitischen Wechselwirkungen, spielten Fragen der politischen Partizipation von Frauen oder gar Genderaspekte von Politik eine sehr marginale Rolle. Ein Umstand der sich noch heute in den geringen Zahlen weiblicher Abgeordneter oder von Frauen in wirtschaftlichen und politischen Spitzenpositionen widerspiegelt. Am Beispiel des Irak soll dieser Umstand einer näheren Betrachtung unterzogen werden. Es soll zum einen die Frage nach den allgemeinen politischen und wirtschaftlichen Perspektiven dieses Umstands gehen. Zum anderen soll anhand der Bedeutung von Partizipation und Genderaspekten von Politik die These hervorgehoben werden, dass die Einführung von Quoten unabdingbar erscheint für die Herausbildung eines auf Gleichberechtigung beruhenden politischen Systems. Diese theoretische Herangehensweise soll in einem weiteren Schritt und im Sinne einer historischen Aufzeichnungen der Etappen und der Errungenschaften weiblicher Partizipation im Irak aufgezeigt werden.

description: This is the second in a series of reports on the current wave of youth civic engagement in Egypt. Our goal is to offer an on-the-ground account of the unfolding political changes in Egypt from the perspective a small group of young activists from Cairo and Alexandria. Our first report was based on interviews with these youth who described their involvement in the demonstrations of early 2011 that led to the resignation of Hosni Mubarak. We viewed their comments in terms of a social-movement approach to civic engagement. These young people spelled out their grievances against Mubarak’s government, the ideological outlook they shared on political reform, the opportunities that enabled their actions, and the organizational apparatus that made this momentous event possible (Barber & Youniss, 2012). This paper is a reflective analysis of questions that have emerged in our research. We continued to interview these same youth activists over the past year and correlated their evolving views first with our further exploration of Egypt’s complex political situation and second with our knowledge of recent social scientific thought regarding civic engagement among youth. This triangulation leads us to consider three kinds of questions: 1) how to assess civic engagement adequately in a population of youth that lived under politically restrictive conditions; 2) how new definitions of active Egyptian citizenship are emerging; and 3) what these new definitions imply for engagement in the future.

description: We introduce FlexibleSUSY, a Mathematica and C++ package, which generates a fast, precise C++ spectrum generator for any SUSY model specified by the user. The generated code is designed with both speed and modularity in mind, making it easy to adapt and extend with new features. The model is specified by supplying the superpotential, gauge structure and particle content in a SARAH model file; specific boundary conditions e.g. at the GUT, weak or intermediate scales are defined in a separate FlexibleSUSY model file. From these model files, FlexibleSUSY generates C++ code for self-energies, tadpole corrections, renormalization group equations (RGEs) and electroweak symmetry breaking (EWSB) conditions and combines them with numerical routines for solving the RGEs and EWSB conditions simultaneously. The resulting spectrum generator is then able to solve for the spectrum of the model, including loop-corrected pole masses, consistent with user specified boundary conditions. The modular structure of the generated code allows for individual components to be replaced with an alternative if available. FlexibleSUSY has been carefully designed to grow as alternative solvers and calculators are added. Predefined models include the MSSM, NMSSM, E$_6$SSM, USSM, R-symmetric models and models with right-handed neutrinos.

Hidden physics in the dual-fermion approach - a special case of a non-local expansion scheme

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: In this work, we present a nonlocal expansion scheme to study correlated electron systems aiming at a better description of its spatial fluctuations at all length scales. Taking the nonlocal coupling as a perturbation to the local degrees of freedom, we show that the nonlocality in the self-energy function can be efficiently constructed from the coupling between local fluctuations. It can provide one unified framework to incorporate nonlocality to both ordered and disordered correlated many-body fermion systems. In this application, we prove that the dual-fermion approach can be understood as a special case of this nonlocal expansion scheme. The scheme presented in this work is constructed without introducing any dual variable, in which the interacting nature and the correlated behaviors of the lattice fermions have a clear physics correspondence. Thus, in this special case, the equivalence of the dual-fermion approach to the nonlocal expansion scheme beautifully reveals the physics origin of the dual variables. We show that the noninteracting dual-fermion Green's function corresponds exactly to a nonlocal coupling of the lattice fermion renormalized by the local single-particle charge fluctuations, and the dual-fermion self-energy behaves as the one-particle fully irreducible components of the lattice Green's function. Not only limited to this specific example, the nonlocal expansion scheme presented in this work can also be applied to other problems depending on the choice of the local degrees of freedom.

description: Spin-glass theory is one of the leading paradigms of complex physics and describes condensed matter, neural networks and biological systems, ultracold atoms, random photonics, and many other research fields. According to this theory, identical systems under identical conditions may reach different states and provide different values for observable quantities. This effect is known as Replica Symmetry Breaking and is revealed by the shape of the probability distribution function of an order parameter named the Parisi overlap. However, a direct experimental evidence in any field of research is still missing. Here we investigate pulse-to-pulse fluctuations in random lasers, we introduce and measure the analogue of the Parisi overlap in independent experimental realizations of the same disordered sample, and we find that the distribution function yields evidence of a transition to a glassy light phase compatible with a replica symmetry breaking.

description: This paper is an attempt to analyse the new and exciting times occurring currently in the Middle East. I will be examining the role of women during the Arab Spring by taking a social constructivist position. As well as this I aim to find analyses in Islamic feminist literature which deals with the issue of religion, gender and patriarchy within specific cultural and religious backgrounds. This will be complimented with a community psychological approach by assessing the issues of marginalization, concientization and empowerment presented by the media articles under analysis written by female Arab journalists, bloggers and activists.

description: This paper reports experimental results on self-organizing wireless networks carried by small flying robots. Flying ad hoc networks (FANETs) composed of small unmanned aerial vehicles (UAVs) are flexible, inexpensive and fast to deploy. This makes them a very attractive technology for many civilian and military applications. Due to the high mobility of the nodes, maintaining a communication link between the UAVs is a challenging task. The topology of these networks is more dynamic than that of typical mobile ad hoc networks (MANETs) and of typical vehicle ad hoc networks (VANETs). As a consequence, the existing routing protocols designed for MANETs partly fail in tracking network topology changes. In this work, we compare two different routing algorithms for ad hoc networks: optimized link-state routing (OLSR), and predictive-OLSR (P-OLSR). The latter is an OLSR extension that we designed for FANETs; it takes advantage of the GPS information available on board. To the best of our knowledge, P-OLSR is currently the only FANET-specific routing technique that has an available Linux implementation. We present results obtained by both Media Access Control (MAC) layer emulations and real-world experiments. In the experiments, we used a testbed composed of two autonomous fixed-wing UAVs and a node on the ground. Our experiments evaluate the link performance and the communication range, as well as the routing performance. Our emulation and experimental results show that P-OLSR significantly outperforms OLSR in routing in the presence of frequent network topology changes.

The New Global Cycle of Protest and the Portuguese Case

description: This paper focuses on the recent cycle of collective action across countries and continents over the past few years. It seems to be evident that in the outset of 2011 began a new wave of global protests made of contagion and communication that spread in different contexts. Our argument is that, unlike other cycles marked by post-materialistic values, changes in labour and material issues have gained a new centrality. The labour and social basis of these mobilizations is particularly evident, though not exclusive, linking up with disaffection towards political institutions and a crisis of legitimacy of elites in power. We will take the example of the demonstration of 12th March in Portugal as an expression of some of the features in this emerging type of mobilization, where youth plays a leading role. It is from the empirical information concerning this public protest that we will build our analysis, identifying in the Portuguese reality parallels with the international context but also national peculiarities, dynamics of continuity and rupture in relation to the historical past.

description: Several known results, by Rivin, Calegari-Maher and Sisto, show that an element $ϕ_n\in Out(F_r)$, obtained after $n$ steps of a simple random walk on $Out(F_r)$, is fully irreducible with probability tending to 1 as $n\to\infty$. In this paper we construct a natural "train-track directed" random walk $\mathcal W$ on $Out(F_r)$ (where $r\ge 3$). We show that, for the element $ϕ_n\in Out(F_r)$, obtained after $n$ steps of this random walk, with asymptotically positive probability the element $ϕ_n$ has the following properties: $ϕ_n$ is an ageometric fully irreducible, which admits a train-track representative with no periodic Nielsen paths and exactly one nondegenerate illegal turn, that $ϕ_n$ has "rotationless index" $\frac{3}{2}-r$ (so that the geometric index of the attracting tree $T_{ϕ_n}$ of $ϕ_n$ is $2r-3$), has index list $\{\frac{3}{2}-r\}$ and the ideal Whitehead graph being the complete graph on $2r-1$ vertices, and that the axis bundle of $ϕ_n$ in the Outer space $CV_r$ consists of a single axis.

Facing the Economic Crisis in Greece: The Effects of Grievances, Real and Perceived Vulnerability, and Emotions Towards the Crisis on Reactions to Austerity Measures

description: This research was conducted in Greece during a period of major economic crisis when everyday events contributed to a changing and threatening socio-political environment. The paper looks at the structure of reactions Greek people (N=1040) have towards the crisis. Informed by social psychological theories of collective action and relative deprivation it is hypothesized that these reactions would depend on people's actual financial position, their sense of grievances and feelings of vulnerability and the emotions they felt towards the crisis. Results show that people have multiple ways of reacting that go from radical and even violent practices towards individual solutions and depression. These reactions are differently predicted by people's position, feelings of vulnerability and sense of grievances and by different emotions. It is not people's actual position that influences reactions and feelings of vulnerability are a major predictor. Moreover, sense of grievances are linked to more radical forms of action but also to depression. Emotions play an important role in predicting reactions to the crisis. Anger is confirmed as a predictor of political participation and collective action whereas fear and frustration are a major predictor of depression. Positive emotions also predict collective action with the exception of violent practices.

From Tahrir Square to Open Space: Practical Experiences with Open Space Technology in Egypt

description: The Egyptian revolution started literally with an open space: at the Tahrir Square in the heart of Cairo. Here it was where many Egyptians for the first time in their lives made the experience of freely talking about politics in public. Since January 2011, many young Egyptians are trying to keep up this “Tahrir experience” by experimenting with new forms of political debate and civic education in Egypt. It was this spirit that resulted in the idea of introducing the Open Space Technology (OST) as a new format of civic education in Egypt. In March 2011 the authors of this article, both working in Egypt for many years, organized the first Open Space in the country. This event encouraged many other national and international institutions and initiatives to adopt and further develop OST in Egypt and other Arab countries. The unexpected popularity of OST in revolutionary Egypt proved that it is in fact the right methodology at the right time in the right context and the right place. OST is a meeting format that fosters dialogue and exchange in a democratic way. It is easy to organize and non-costly. It invites for sharing opinions, discovering common ground, discussing and tackling differences. It helps generating ideas and reflecting about their implementation. This article argues that Open Space (OS), therefore, is a format that perfectly fits the transforming political environment and the socio-cultural setting of Egypt and – most probably – other Arab transformation-states.

description: We present NNPDF3.0, the first set of parton distribution functions (PDFs) determined with a methodology validated by a closure test. NNPDF3.0 uses a global dataset including HERA-II deep-inelastic inclusive cross-sections, the combined HERA charm data, jet production from ATLAS and CMS, vector boson rapidity and transverse momentum distributions from ATLAS, CMS and LHCb, W+c data from CMS and top quark pair production total cross sections from ATLAS and CMS. Results are based on LO, NLO and NNLO QCD theory and also include electroweak corrections. To validate our methodology, we show that PDFs determined from pseudo-data generated from a known underlying law correctly reproduce the statistical distributions expected on the basis of the assumed experimental uncertainties. This closure test ensures that our methodological uncertainties are negligible in comparison to the generic theoretical and experimental uncertainties of PDF determination. This enables us to determine with confidence PDFs at different perturbative orders and using a variety of experimental datasets ranging from HERA-only up to a global set including the latest LHC results, all using precisely the same validated methodology. We explore some of the phenomenological implications of our results for the upcoming 13 TeV Run of the LHC, in particular for Higgs production cross-sections.
