description: APOGEE spectra offer $\lesssim$1 km s$^{-1}$ precision in the measurement of stellar radial velocities (RVs). This holds even when multiple stars are captured in the same spectrum, as happens most commonly with double-lined spectroscopic binaries (SB2s), although random line of sight alignments of unrelated stars can also occur. We develop a code that autonomously identifies SB2s and higher order multiples in the APOGEE spectra, resulting in 7273 candidate SB2s, 813 SB3s, and 19 SB4s. We estimate the mass ratios of binaries, and for a subset of these systems with sufficient number of measurements we perform a complete orbital fit, confirming that most systems with period $

description: Due to the short settling times of metals in DA white dwarf atmospheres, any white dwarfs with photospheric metals must be actively accreting. It is therefore natural to expect that the metals may not be deposited uniformly on the surface of the star. We present calculations showing how the temperature variations associated with white dwarf pulsations lead to an observable diagnostic of the surface metal distribution, and we show what constraints current data sets are able to provide. We also investigate the effect that time-variable accretion has on the metal abundances of different species, and we show how this can lead to constraints on the gravitational settling times.

description: We present measurements of the semileptonic decays B- --> D0 tau- nubar, B- --> D*0 tau- nubar, B0bar --> D+ tau- nubar, and B0bar --> D*+ tau- nubar, which are potentially sensitive to non--Standard Model amplitudes. The data sample comprises 232x10^6 Upsilon(4S) --> BBbar decays collected with the BaBar detector. From a combined fit to B- and B0bar channels, we obtain the branching fractions B(B --> D tau- nubar) = (0.86 +/- 0.24 +/- 0.11 +/- 0.06)% and B(B --> D* tau- nubar) = (1.62 +/- 0.31 +/- 0.10 +/- 0.05)% (normalized for the B0bar), where the uncertainties are statistical, systematic, and normalization-mode-related.

description: Objectif :     Etant donné que les jeunes pousses des feuilles de Megaphynium Macrostachym constituent les produits non ligneux appréciés comme légumes et consommés par les populations de certaines tribus en République Démocratique du Congo et dans d’autres pays africains ne sont disponibles qu’en saison des pluies, cette étude s’est proposée de contribuer à la conservation de ces  jeunes pousses pour une alimentation humaine.

Méthodologie  et  résultats : les jeunes pousses des feuilles de  Megaphynium Macrostachym  ont été arrachées dans la forêt à Idiofa, puis décortiquées en les débarrassant des parties très dures et lavées puis trempées dans des bocaux en plastique contenant 250 g de NaCl et 5 cl de vinaigre. Six mois après, ce produit a été distribué à 103 personnes d’âge supérieur à 20 ans ayant déjà consommées ces légumes à qui un questionnaire a été distribué pour récolter les avis sur cette plante conservée. Les résultats obtenus ont montré que ce produit garde sa valeur naturelle et est apprécié par 98% d’individus, le produit bouilli ou non bouilli avant conservation a gardé la couleur blanche naturelle.

description: We analyze the stability of the Einstein static universe by considering homogeneous scalar perturbations in the context of f(R) modified theories of gravity. By considering specific forms of f(R), the stability regions of the solutions are parameterized by a linear equation of state parameter w=p/rho. Contrary to classical general relativity, it is found that in f(R) gravity a stable Einstein cosmos with a positive cosmological constant does indeed exist. Thus, we are lead to conclude that, in principle, modifications in f(R) gravity stabilize solutions which are unstable in general relativity.

description: We present an analysis of mock X-ray spectra and light curves of magnetic cataclysmic variables using an upgraded version of the 3D CYCLOPS code. This 3D representation of the accretion flow allows us to properly model total and partial occultation of the post-shock region by the white dwarf as well as the modulation of the X-ray light curves due to the phase-dependent extinction of the pre-shock region. We carried out detailed post-shock region modeling in a four-dimensional parameter space by varying the white dwarf mass and magnetic field strength as well as the magnetosphere radius and the specific accretion rate. To calculate the post-shock region temperature and density profiles, we assumed equipartition between ions and electrons, took into account the white dwarf gravitational potential, the finite size of the magnetosphere and a dipole-like magnetic field geometry, and considered cooling by both bremsstrahlung and cyclotron radiative processes. By investigating the impact of the parameters on the resulting X-ray continuum spectra, we show that there is an inevitable degeneracy in the four-dimensional parameter space investigated here, which compromises X-ray continuum spectral fitting strategies and can lead to incorrect parameter estimates. However, the inclusion of X-ray light curves in different energy ranges can break this degeneracy, and it therefore remains, in principle, possible to use X-ray data to derive fundamental parameters of magnetic cataclysmic variables, which represents an essential step toward understanding their formation and evolution.

description: Each country lives its own reality, has individual pressures and particular interests; furthermore, the aghcultural sector of the poor and developing countries, due to their special topographical, climatic and latitude conditions has to be divided in two parts; on one side, where there is a high grade of automatization and mechanization and, on the other, as it is the specific case of the Colombian coffee industry, basically of high slopes, where the productive processes become practically handicraft schemes. Taking into consideration the above fact, I do not think there are magic formulas to design commercial policies, but I would like to explain the successful pattern of the Colombian coffee industry, where the growers, in association with the government, have designed their own external and domestic marketing policies.

description: The following threepartite contribution rests on the presentations made in the context of the '16. Wissenschaftliche Tagung der Kriminologischen Gesellschaft', September 5-7, in Vienna. In Part I the authors set out to introduce alternative concepts and alternative practices of justice and security as they have been tried out in the course of a large EU financed scientfic project: 'Developing alternative understandings of security and justice through restorative justice approaches in intercultural settings within democratic societies - ALTERNATIVE'. In the first part we present the outlines of this project and we explicate the rationale of restorative justice that has been underlying this project. Restorative justice has become a rapidly growing field of research and practice, with the criminal justice system as the gravitational centre at its core. Within the criminal justice system, restorative justice promotes alternatives to punishment in dealing with the aftermath of crime. The application of restorative justice in complex, urban, or intercultural contexts and therefore to social issues and conflicts which do not fall within the category of 'crime' remains less explored. Yet such restorative practices raise a whole set of conceptual and practical challenges around restorative approaches to conflict resolution and their effects. We report in the following parts on two of Alternative’s action research projects, one in Vienna and one in a small Hungarian town.

description: Farming in the UK has evolved as a result of climatic conditions, and the inherent features of the various soil types, mostly laid down in the Ice Ages. Human endeavours over the centuries, influenced by social and economic factors, has provided the patterned agriculture visible today. The physical and financial characteristics of the present farm systems are described, including their capital and labour requirements. The trends in farm profitability is also featured, including the effects of EEC policy. New management issues, largely as a result of the "greening” of the countryside, "natural” foods and human health, are discussed to give a balanced view of current farming conditions and hopes and fears of the future.

Management Changes Since the First IFMA Congress

Publisher: name: Unknown
Year: 1995
Subjects: Farm Management

description: There have been sweeping changes in the practice and science of farm management since the First International Farm Management Congress was held in the United Kingdom in 1971.
However the four tenets offarm business management still apply:
1. Recording the financial and physical information;
2. Analysis of the data;
3. Platming (or replanning) the farm business;
4. Controlling the business - that is, budgetary control
Farm businesses are increasing in output, either by acreage or yield, or both. The standard of education is improving rapidly, as is the computer literacy of today's farmers.
Ihe political, social, environmental pressures on farm businesses are causing farm managers to have to consider far wider aspects of their operations than used to be the case.
The long-term outlook for farm businesses is good - in Europe once the CAP is terminated, and in other heavily subsidised agricultural industries once they too follow New Zealand’s lead to full, fair and non-subsidised trade.

Die Ergebnisse zeigen, dass das Begehen von Sachbeschädigungen etwa doppelt so verbreitet im Jugendalter ist wie das Begehen von Graffitisprühen. Die Prävalenzraten zu Sachbeschädigungen sind im Zeitverlauf gesunken, zum Graffitisprühen hingegen nicht. Die Einflussfaktoren sind weitestgehend vergleichbar. Allerdings gilt, dass Jugendliche in grossstädtischen Kontexten, mit einem Migrationshintergrund und Kontakt zu einem Umfeld, in dem Drogen konsumiert werden, eher Graffitis sprühen; Jugendliche ohne Migrationshintergrund, die im ländlichen Umfeld leben und Kontakte zu einer delinquenten Subkultur aufweisen, neigen hingegen stärker zur Ausübung von Sachbeschädigungen.
Top quark induced vacuum misalignment in little higgs models
Creators: name: Grinstein, Benjamin

Publisher: name: arXiv
Year: 2008
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We show that the effect of the top quark can dominate over the effect of the gauge sector in determining the vacuum alignment in little higgs (LH) models. We demonstrate that in the littlest LH model and the SU(2)xSU(2)xU(1) LH model, ensuring that the correct vacuum alignment is chosen requires that a subset of the gauge sector couplings be large to overcome the effect of the top quark. We quantify this effect by deriving bounds on the couplings in the gauge sector and demonstrate that these bounds provide a compelling theoretical reason for the gauge coupling constant hierarchy in the SU(2)xSU(2)xU(1) model that reduces the Goldstone decay constant scale to a TeV. We also argue that for a class of LH models with T parity the top quark drives the correct vacuum alignment and therefore all gauge couplings can be small.

Atlas

description: The Atlas of dance photography is a manifold project. It is an exhibit and also a research method. It collects part of figurative heritage of dance from the beginning of the past century and pushes it towards defining a field of research as well as a subject of inquiry. A field where figurative procedures interlace with choreutic experimentations, cultural trajectory with professional requirement, technical problems with artistic instances. The Atlas is composed of panels that cover a number of thematic areas and recurring formulations of the representation of the moving body; it constitutes the visual and experimental dimension of the research on dance photography conducted by a group of newly graduated students and photographers coordinated by Samantha Marenzi together with Dams of Università Roma Tre and Officine Fotografiche Roma. Among the accomplishments, a website/archive which collects photos, biographies and bibliographies on the dance photography of the early 20th century (www.fotografiaedanza.it), and a volume/catalogue that originates from the experience of an ongoing laboratory, diversified in vocational provenance and scientific maturity, where the first scientific and figurative results of the Atlas are gathered. This contribution presents the index together with some panels, short passages and incipit of a number of essays from the catalogue La camera meravigliosa.

description: We report the discovery of a new young stellar cluster and molecular cloud located in the far outer Galaxy, seen towards IRAS 06361-0142, and we characterise their properties. Near-infrared images were obtained with VLT/ISAAC through JHKs filters, millimetre line observations of CO(1-0) were obtained with SEST, and VLA 6 cm continuum maps obtained from archive data. The cloud and cluster are located at a distance of 7 kpc and a Galactocentric distance of 15 kpc, well in the far outer Galaxy. Morphologically, IRAS 06361-0142 appears as a cluster of several tens of stars surrounded by a nearly spherical nebular cavity centred at the position of the IRAS source. The cluster appears composed of low and intermediate-mass, young reddened stars with a large fraction having cleared the inner regions of their circumstellar discs responsible for (H - Ks) colour excess. The observations are compatible with a 4 Myr cluster with variable spatial extinction between Av = 6 and Av = 13.

description: Verhetzung, Hasskriminalität, bewusste Falschinformation und Verschwörungstheorien auf Social Media stellen Justiz, Kriminalforschung und damit die Gesellschaft vor beinahe unüberblickbare Herausforderungen. Ständig wechselnde Plattformen, Menge, Geschwindigkeit, Unstrukturiertheit und Inhomogenität der Daten selbst (Stichwort Big Data), sowie die unterschiedliche Verwendung von Sprache in Kombination mit textuellen, visuellen und auditiven Elementen (mash-up) bilden die immense Komplexität für die Verarbeitung von Daten aus Social Media. Aus diesem Grund versagen hier herkömmliche Verfahren der Datenerhebung und Datenanalyse zunehmend (Boyd 2011, Unseld 2013, Reichert 2014). Verfahren aus dem Bereich des Natural Language Processing, insbesondere aus den Bereichen der Polaritäts- und Sentiment-Analyse (Shalunts, 2015), bieten hier aktuelle Ansätze, um mit den großen Datenmengen sinnvoll umzugehen. Neuere Entwicklungen aus dem Bereich des Machine Learning stellen zusätzliche Annäherungen dar. Während diese technischen Ansätze die Verarbeitung großer Datenmengen ermöglichen, weisen sie Schwächen in der Rückbindung des Datenmaterials auf. Das Dilemma besteht darin, dass die hohe Effizienz automatisierter Verfahren häufig mit einem Mangel an Validität einhergeht. Genauer: Man findet zwar (immer) Strukturen in den Daten, weiß aber nicht (immer), was sie bedeuten. Schließlich entwickelten sich herkömmliche Verfahren der konventionellen Datenanalyse aus über Jahrzehnte gewachsenen wissenschaftstheoretischen und methodologischen Ansprüchen, von denen die aktuellen Verfahren der automatisierten Analyse weit entfernt sind (Scharkow 2011). Um nun soziale Medien angemessen erfassen und analysieren zu können, muss eine Reihe methodischer Probleme bewältigt werden, zu denen nun die Sozialwissenschaft gemeinsam mit der Informatik neue vielsprechende Ansätze entwickeln. Die Lösung: Eine Kombination aus computerunterstützter Datenanalyse, einer quantitativen Inhaltsanalyse und schließlich qualitativer Feinarbeit. Am Fallbeispiel der „Identitären Bewegung“ und ihrer Social Media Präsenz soll dieser Beitrag Einblick geben, wie ein interdisziplinäres Vorgehen aussieht, wenn Informatiker, Kommunikationswissenschaftler und nicht zuletzt Juristen und Kriminalsoziologen ihre Konzepte, Fähigkeiten und Methoden bündeln, um Kriminalität im Internet systematisch aufzuspüren und zu analysieren.

description: Twenty-five years ago the daring purchase of260 acres (105 hectares) began the creation of today's 1076 acre (436 hectares) sole proprietorship, Smith Farms, (Summitville, Indiana). The purpose of this paper is to share the education and experience that have been primary influences in the farm's expansion and profitability. The farm management decisions discussed in this paper include marketing, expense management, investment efficiency, and application of research and technology in crop production. Smith Farms started in December 1971 with the purchase of a very neglected swampy farm. My wife and I lived and taught 120 miles from the farm. We finished the school year and moved to the farm in June 1972. We planted and harvested our first crop in 1972. We took teaching positions in nearby schools in the fall of1972 and continued teaching and farming.

description: This paper describes the management of a fairly typical Northern Natal, South Africa, Beef and Sheep farm. It will begin by describing and emphasising the veld (grassland) management system used since this is by far the cheapest resource available on the farm and hence optimum veld management has probably the single most impact on the long term profitability of the enterprise. The paper will also briefly describe the production systems used in the beef and sheep enterprises and how these systems relate to the veld management system. The maize and summer and winter pasture enterprises are supplementary to the main beef and sheep enterprises and shall be briefly included. Labour, purchasing and marketing management strategies will be indicated and finally some financial information will be presented to give a net return per R 1 000 of operating expenditure.

description: Ziel: Der Beitrag behandelt die Befunde einer Studie, die im Auftrag der Deutschen Bischofskonferenz (DBK) die Fälle des sexuellen Missbrauchs an Minderjährigen innerhalb der deutschen katholischen Kirche untersuchte. Die Studie hatte zum Ziel, den Umfang der sexuellen Missbrauchsfälle an Kindern und Jugendlichen zu erheben und zu untersuchen, inwieweit bestimmte Strukturen und Dynamiken in der katholischen Kirche die Tatbegehung begünstigen. Methode: Die Studie bestand aus sieben Teilprojekten. Es wurden qualitative und quantitative Untersuchungsmethoden angewandt. U.a. wurden 38.156 Personalakten katholischer Geistlicher im Zeitraum zwischen 1946 bis 2014 analysiert, 243 Strafakten von Mitarbeitern der katholischen Kirche ausgewertet und qualitative Interviews mit 214 Betroffenen und 50 Beschuldigten geführt. Ergebnisse: Aus der Personalaktenanalyse ging hervor, dass 1.670 Kleriker des sexuellen Missbrauchs an Minderjährigen beschuldigt wurden. Dies entspricht einer Prävalenzrate von 4,4 % des Klerus insgesamt. Den Beschuldigten wurden 3.677 Opfer zugeordnet. Die Strafakten betrafen 209 Beschuldigte, denen 645 Betroffene zugeordnet werden konnten. Die Opfer waren mehrheitlich männlich und waren zum Zeitpunkt des Missbrauchs etwa 12 Jahre alt. Überwiegend wurde von Tathandlungen mit Körperkontakt berichtet. Im Durchschnitt lag für die einzelnen Opfer die Dauer des Missbrauchsgeschehens bei etwa 1,5 Jahren. Schlussfolgerung: Die berichteten Daten zur Häufigkeit des sexuellen Missbrauchs in der deutschen katholischen Kirche stellen eine untere Schätzrate dar. Die sexuellen Missbrauchsdelikte sind nicht nur auf das Fehlverhalten einzelner Personen zurückzuführen, vielmehr sind die Taten auch durch strukturelle Probleme bedingt. Eine umfassende Präventionsarbeit und eine unmittelbare Reaktion auf stattgefundene Missbrauchsfälle sind zwingend erforderlich.

description: Linear polarimetric transformations of light polarization states by the action of material media are fully characterized by the corresponding Mueller matrices, which contain in an implicit and intricate manner all measurable information on such transformations. The general characterization of Mueller matrices relies on the nonnegativity of the associated coherency matrix, which can be mathematically formulated through the nonnegativity of its eigenvalues. The enormously involved explicit algebraic form of such formulation prevents its interpretation in terms of simple physical conditions. In this work, a general and simple characterization of Mueller matrices is presented based on their statistical structure. The concepts associated with the retardance, enpolarization and depolarization properties as well as the essential coupling between the two latter are directly described in the light of the new approach.

description: The origin of magnetic frustration was stated and the ions whose shift is accompanied by emerging magnetic ordering and ferroelectricity in TbMn2O5 and BiMn2O5 were determined on the basis of calculation of magnetic coupling parameters by using the structural data. The displacements accompanying the magnetic ordering are not polar, they just induce changes of bond valence (charge disordering) of Mn1 and Mn2, thus creating instability of the crystal structure. To approximate again the bond valence to the initial value (charge ordering) under magnetic ordering conditions is possible only due to polar displacement of Mn2 (or O1) and O4 ions along the b axis that is the cause of ferroelectric transition.

description: Nach einer kurzen Einführung in das Themenfeld Cybercrime mit den verschiedenen Delikts- und Phänomenbereichen stellt der Beitrag das methodische Vorgehen und erste Ergebnisse einer CATI-Befragung mit 5.000 Unternehmen ab 10 Beschäftigten in Deutschland zur Betroffenheit, zu den vorhandenen IT-Sicherheitsmaßnahmen sowie zu den Folgen der schwerwiegendsten Cyberangriffe vor. Zu den zentralen Befunden zählt, dass viele Unternehmen innerhalb eines Jahres von verschiedenen Cyberangriffsarten betroffen sind, obwohl insbesondere technische Sicherheitsmaßnahmen vorhanden waren. Phishing und Schadsoftware-Angriffe zählen zu den am häufigsten erlebten Angriffsarten, werden aber nur relativ selten angezeigt, womit von einem sehr großen Dunkelfeld ausgegangen werden kann.

description: In the last few years the derivative expansion of the Non-Perturbative Renormalization Group has proven to be a very efficient tool for the precise computation of critical quantities. In particular, recent progress in the understanding of its convergence properties allowed for an estimate of the error bars as well as the precise computation of many critical quantities. In this work we extend previous studies to the computation of several universal amplitude ratios for the critical regime of $O(N)$ models using the derivative expansion of the Non-Perturbative Renormalization Group at order $\mathcal{O}(\partial^4)$ for three dimensional systems.

Übergangsmanagement
Strafvollzug
Europäischer Vergleich

description: Die Verbesserung der Gestaltung des Übergangs vom Strafvollzug in die Freiheit ist in den letzten 20 Jahren ein zentrales Thema der Strafvollzugspraxis und –Forschung geworden. Unter dem Schlagwort des Übergangsmanagements sind zahlreiche Praxismodelle entstanden, die zu einer Reduzierung des häufig sehr schnellen Rückfalls nach einer Entlassung aus dem Strafvollzug beitragen sollen. Der Beitrag basiert auf einem rechtsvergleichend angelegten Projekt mit 20 europäischen Ländern, das erfolgversprechende Praxisprojekte und die Gesetzgebung und Praxis zur Entlassungsvorbereitung, (bedingten) Entlassung und Nachsorge untersucht hat (vgl. Dünkel/Pruin/Storgaard/Weber 2019). Trotz einiger guter Ansätze zeigt sich, dass kaum irgendwo flächendeckende Kooperationsmodelle implementiert oder die Schwierigkeiten der Zusammenarbeit der Akteure innerhalb und außerhalb des Strafvollzugs tatsächlich überwunden wurden.
Finite temperature Mott transition in Hubbard model on anisotropic triangular lattice

description: We investigate the Hubbard model on the anisotropic triangular lattice by means of the cellular dynamical mean field theory. The phase diagram determined in the Hubbard interaction versus temperature plane shows novel reentrant behavior in the Mott transition due to the competition between Fermi-liquid formation and magnetic correlations under geometrical frustration. We demonstrate that the reentrant behavior is characteristic of the Mott transition with intermediate geometrical frustration and indeed consistent with recent experimental results of organic materials.

Farm Management on My Farm
Creators: name: Ross, Barbara
Publisher: name: Unknown
Year: 1995
Subjects: Farm Management

description: This paper introduces the author's farm, and elaborates several problems which have arisen in recent years. The problems have resulted from changes in the trading environment, and also from the use of farming methods inherited from a European tradition which are not suited to Australia. Solutions to these problems are being found by using a management process based on a strategic approach. A set of integrated goals is developed and is then subjected to review by a peer group. Management decisions are tested to ensure they meet benchmark standards and are compatible with the farm business goals. A systematic search for new ideas to meet these goals is revealing new directions for the farm business.

Kontrollieren? Aber warum, wann und wie? Kritische Perspektive auf polizeiliche Identitätsfeststellungen

description: Polizeiliche Identitätsfeststellungen –repressiv und präventiv – werden vielfach als wirksames Mittel angesehen, um das polizeiliche Gegenüber aus der Anonymität zu holen. Entsprechende Kontrollen werden in der Rechtswissenschaft oft als wenig eingriffsintensiv eingestuft. Jedoch zeigen die wiederkehrenden Vorwürfe des Racial-Profilings, dass die Eingriffsintensität tiefergehender sein kann. Bedenkt man zusätzlich, dass die Kontrollen oft mit einem Abgleich mit polizeilichen Datenbanken einhergehen, wird deutlich, dass es sich keineswegs um einen harmlosen Eingriff handelt. Insbesondere, da aufgrund der unklaren Tatbestandsvoraussetzungen die Polizei sehr viel Spielraum hat, wen sie kontrolliert und regelmäßig ihre Auswahl nicht begründen muss. Daher besteht sowohl aus kriminologischer als auch aus rechtswissenschaftlicher Perspektive die Notwendigkeit, die bisher wenig beforschte polizeiliche Identitätsfeststellung näher zu betrachten.
Researching and Promoting the Industrial Uses of Soybeans

description: The soybean is an amazing crop, it can be used whole as food or for a high-protein source of animal feed and a healthy choice for human consumption of necessary fats in the diet In the 1930s and 40s, industrial uses of soy were on the forefront for products such as adhesives and plastics, mh the advent of cheap petroleum and the growing use of beans for livestock feed and human consumption, however, the industrial side of the market became almost dormant. In the past few years, these environmentally friendly industrial uses for soy have come back into favor. The need for cleaner air and water is driving us to again look at soy for a myriad of industrial uses, from adhesives to plastics to crayons to solvents. This paper will chronicle how we have brought soy back into industrial uses and detail some of the products that are currently available and what is currently in active research.

description: We present the first detection of CS in the Antennae galaxies towards the NGC 4038 nucleus, as well as the first detections of two high-J (5-4 and 7-6) CS lines in the center of M 82. The CS(7-6) line in M 82 shows a profile that is surprisingly different to those of other low-J CS transitions we observed. This implies the presence of a separate, denser and warmer molecular gas component. The derived physical properties and the likely location of the CS(7-6) emission suggests an association with the supershell in the centre of M 82.

Characterization of topological insulators based on the electronic polarization with spiral boundary conditions

description: We introduce the electronic polarization originally defined in one-dimensional lattice systems to characterize two-dimensional topological insulators. The main idea is to use spiral boundary conditions which sweep all lattice sites in one-dimensional order. We find that the sign of the polarization changes at topological transition points of the two-dimensional Wilson-Dirac model (the lattice version of the Bernevig-Hughes-Zhang model) in the same way as in one-dimensional systems. Thus the polarization plays the role of "order parameter" to characterize the topological insulating state and enables us to study topological phases in different dimensions in a unified way.

description: Die Nutzung gewalthaltiger Medien durch Jugendliche ist immer wieder Gegenstand medial-öffentlicher und fachlicher Diskussionen. Oftmals fokussiert auf eine rein aggressions­- und wirkungszentrierte Fragestellung bleiben diese Thematisierungen jedoch nicht selten einem reduktionistischen Problemverständnis verhaftet und berücksichtigen kaum die Bedingungen und Zusammenhänge der Rezeption von Mediengewalt durch Jugendliche. Grundlegend ist das Verständnis von Medienrezeption als Interaktion zwischen Medieninhalt und Rezipient. Basis hierfür – und gleichsam eine Kontrastierung zu reduktionistischen Vorstellungen von Medienrezeption und -wirkung – ist der aktive Rezipient, der sich mit den in den Medieninhalten immanenten Botschaften vor dem Hintergrund der eigenen lebensweltlichen Erfahrungen und sozialen Einbettung auseinandersetzt. Die Nutzung von gewalthaltigen Medien steht dabei – wie die Nutzung jeglicher Medien – unter alltäglichen und kulturellen, individuellen und sozialen sowie biographischen und aktuellen Deutungszusammenhängen der Jugendlichen. In dem Beitrag werden Ergebnisse einer Rezeptionsanalyse, bestehend aus Gruppendiskussionen und Einzelinterviews mit insgesamt 15 Jugendlichen, vorgestellt. Vor dem Hintergrund eines interaktionalen Modells der Medien(gewalt)rezeption im Jugendalter werden hierbei die Wahrnehmungs-, Deutungs- und Bewertungsmuster jugendlicher Rezipienten in ihren je spezifischen lebensweltlichen Bezügen genauer betrachtet, wodurch insbesondere auch mögliche funktionale (sozialadäquate und entwicklungsfördende) und dysfunktionale (sozialschädliche und entwicklungsbeeinträchtigende) Aspekte der Rezeption von Mediengewalt herausgearbeitet werden.

description: This paper presents scale invariant/self-similar galactic magnetic dynamo models based on the classic equations, and compares them qualitatively to recently observed magnetic fields in edge-on spiral galaxies. We classify the axially symmetric dynamo magnetic field by its separate sources, advected flux and sub scale turbulence. We neglect the diffusion term under plausible physical conditions. There is a time dependence determined by globally conserved quantities. We show that magnetic scale heights increase with radius and wind velocity. We suggest that AGN outflow is an important element of the large scale galactic dynamo, based on the dynamo action of increasing sub scale vorticity. This leads us to {\it predict} a correlation between the morphology of coherent galactic magnetic field (i.e. extended polarized flux) and the presence of an AGN.
