title: DISTANCE SUBJECT-SUBJECT PEDAGOGICAL INTERACTION IN THE AGE OF COVID-19: THE CHALLENGE OF THE DAY

description: The article discusses the advantages and disadvantages of distance learning in the process of the development of subjectness via information and communication technologies in prospective teachers in the course of their professional training. It is proved that information and communication technologies are a multifunctional learning tool that contributes to the efficiency of independent learning, motivates prospective teachers to further development of their “selves” in the course of their professional training and makes this routine process more interesting and efficient. It is theoretically substantiated that the role of teachers in the educational process in the conditions of distance learning has changed significantly. The teacher of a new breed should give up the traditional dominant role in the educational process, and, instead, in the course of distance pedagogical interaction, get a new role as an organizer, coordinator and mentor of students in the process of independent cognitive activity. It is defined, that interaction between teacher and students is the most important difference between traditional education in the classroom and virtual learning. Problems that may arise in the process of distance interaction between the participants have been identified. The teachers should consider them and do their best to overcome.
The key feature of distance subject-subject pedagogical interaction, which is a significant role of a feedback, is revealed. In a socio-psychological context, it means receiving information from others about how they perceive the behavior of a student in the process of distance interaction. Feedback allows the students to understand and adjust their activities to the optimal strategy of activity in an artificial environment. In the future, students will have the opportunity to put their subjective experience directly into their life.

description: The semiconductor quantum dot nanopillar array in InAs/GaAs was fabricated. In consideration of the quantum dot density, the pillar diameter was determined as only a few quantum dots were involved in a pillar. The lattice constant of a pillar array was optimized such that only one pillar couples to the fiber core without any specific manipulation. Such structural consideration regarding the photon source and the optical setup contributes to the high purity of the single-photon generation. For high extraction efficiency of photons from photon source, we fabricated the metal cavity structure around the pillar array. The combination of dry-etching and wet-etching realizes the functionally designed three-dimensional structure. Such fabrication processes face the realization of the well-optimized single-photon emitter.

description: Several methods to reduce respiratory-induced motion have been described in literature, with the goal of increasing accuracy of treatment to minimize normal tissue toxicity or increase dose to the target volume.
We analyzed two different techniques of respiratory gating: the deep inspiration breath hold technique and the respiratory gating using the Real-time Position Management (RPM) system.
The first method is a self-gating technique in which radiation treatment take place during a phase of breath-holding. 
The second technique use a reflective marker placed on the patient’s anterior surface. The motion of the marker is tracked using a camera interfaced to a computer. The gating thresholds are set when the tumor is in the desired portion of the respiratory cycle. These thresholds determine when the gating system turns the treatment beam on and off. 
We compared both techniques with a standard external radiation treatment. The dosimetric analysis has led to considerable advantage of these methods compared to the external radiation treatment, particularly in reducing the dose to the lung.

Soziale Milieus und alltägliche Klassenpraxis

description: „Alltag“ und „Klasse“ bezeichnen Begriffe, sie sich in der sozialwissenschaftlichen Debatte meist als zwei Pole des Sozialen gegenüberstehen. Dabei ist Alltag tendenziell der Pol, der für das subjektive und gewohnheitsmäßige Erleben steht. Dagegen bezeichnet „Klasse“ eine Kategorie, die vom subjektiven Erleben abstrahiert, und auf die Strukturbedingtheit von Alltagspraxis verweist. Folgt man nun der historischen Debatte, so kann man – bei allen Unterschieden im Detail – doch sagen, dass mit der Verwendung des Milieubegriffs die Thematisierung genau dieses Verhältnisses der beiden Dimensionen des sozialen Lebens im Vordergrund stand. Dabei lässt sich zunächst an Hradil (1992) anknüpfen, der die verschiedenen Entwicklungslinien skizziert hat. Der Begriff „Milieu“ taucht demnach erstmals auf, als es darum geht, die Prägung des Menschen nicht aus biologischer Vererbung, sondern aus ihn umgebenden Umwelteinflüssen heraus zu erklären. Vor allem durch die Industrialisierung wurde deutlich, „wie sehr die menschliche Existenz abhängig ist von äußeren, und zwar von menschengemachten, sozialen Umständen“ (Hradil 1992: 21).

The Importance of XUV Radiation as a Solution to the P V Mass Loss Rate Discrepancy in O-Stars

description: A controversy has developed regarding the stellar wind mass loss rates in O-stars. The current consensus is that these winds may be clumped which implies that all previously derived mass loss rates using density-squared diagnostics are overestimated by a factor of ~ 2. However, arguments based on FUSE observations of the P V resonance line doublet suggest that these rates should be smaller by another order of magnitude, provided that P V is the dominant phosphorous ion among these stars. Although a large mass loss rate reduction would have a range of undesirable consequences, it does provide a straightforward explanation of the unexpected symmetric and un-shifted X-ray emission line profiles observed in high energy resolution spectra. But acceptance of such a large reduction then leads to a contradiction with an important observed X-ray property: the correlation between He-like ion source radii and their equivalent X-ray continuum optical depth unity radii. Here we examine the phosphorous ionization balance since the P V fractional abundance, q(P V), is fundamental to understanding the magnitude of this mass loss reduction. We find that strong "XUV" emission lines in the He II Lyman continuum can significantly reduce q(P V). Furthermore, owing to the unique energy distribution of these XUV lines, there is a negligible impact on the S V fractional abundance (a key component in the FUSE mass loss argument). We conclude that large reductions in O-star mass loss rates are not required, and the X-ray optical depth unity relation remains valid.

Milieu als soziologisches Modell oder als historische Praxis?

description: Der Aufschwung der Milieuforschung begann in den 1960er und 1970er Jahren als Versuch, angesichts zunehmender gesellschaftlicher Differenzierung fehlende Dimensionen der Gesellschaftsanalyse wiederzuentdecken. Dieser richtete sich vor allem gegen die dominanten Ansätze der Klassenund Schichtungssoziologie, die soziale Praxis, Mentalitäten und Zugehörigkeiten aus vertikalen ökonomischen Unterschieden abzuleiten versuchten und die sich dabei insbesondere auf die klassische Soziologie von Weber bzw. von Marx beriefen. Diese Berufung erfolgte, wie ich darlegen möchte, zu Unrecht. Ein Textstudium erster Hand ergibt, dass die Ansätze der klassischen Soziologie – von Marx über Durkheim, Veblen, Weber und Geiger bis hin zu Bourdieu – in Wirklichkeit gerade mit dem ökonomistischen Reduktionismus gebrochen haben und einer differenziert und historisch konzipierten Praxistheorie gefolgt sind, nach der soziales Handeln relativ autonomen Eigenlogiken folgt, auch wenn es nicht frei von historischen und ökonomischen Bedingtheiten ist.

description: Abstract

The academic environment has recently recognized the importance and benefits that an extensive research on the translation of advertising can have for translation studies. Despite the growing interest and increasing research activity in the field it is still difficult to speak about a theory of advertising translation in general. There is a need for further study encompassing different languages and both heterogeneous and homogenous cultures that will give the possibility to receive a more complete map of what the translation of advertising is and should be. Previous studies have been concentrated, for the most part, on Western European language pairs. This study is a research into perfume and cosmetics print advertisements translated from English into Russian where both visual and verbal elements are considered. Three broad translation approaches have been identified in what concerns the verbal message: Translated message, parallel translation, recreated adverts, and three approaches in dealing with the image: similar images, modified images, completely different images. The thesis shows that where Russian advertisements for perfume products tend to have a message, or create one, this is often lacking in the English copy. The article ends by suggesting that perfume advertisements favor the standardization approach when entering Russian market. The attempts to localize the advert have also been noticed although they are obviously less numerous in perfume adverts and are rather instances of adaptation - a mix between the localization and standardization approaches since they keep drawing on the same globally accepted universals about female beauty and concern for ‘woman’s identity’ (we focused our analysis on products designed for female consumers). This study, complementing previous studies, aims to be a contribution to the description of laws and strategies that guide the translation of advertising texts into Russian.
Zentrale Entwicklungstendenzen sozialer Milieus in Deutschland

description: Der Milieubegriff hat sich in den Sozialwissenschaften zur Beschreibung von Grundstrukturen der Bevölkerung und damit auch zu zeitdiagnostischen Zwecken etabliert (Schulze 1992; Vester et al. 2001). In dieser Forschung werden häufig Thesen über die Veränderung von sozialen Milieus im Zeitverlauf formuliert. Nicht selten wird dabei die klassische Arbeit von Lepsius (1990) über sozialmoralische Milieus im deutschen Kaiserreich und der Weimarer Republik als Referenz herangezogen, die paradigmatisch die Struktur der sozialen Milieus in dieser historischen Phase beschrieben hat, wobei er auf der Grundlage der Merkmale Klassenzugehörigkeit, Konfession und Nationalität vier sozialmoralische Milieus unterschieden hat: das mehrheitlich protestantische sozialdemokratische Arbeitermilieu, das Milieu der protestantischen und agrarischen Konservativen sowie das ebenfalls protestantische liberal-bürgerliche Milieu. Davon abgegrenzt waren das klassenübergreifend konstituierte katholische Milieu sowie die Milieus der nationalen Minderheiten in Deutschland, die Lepsius allerdings nur kursorisch berührt hat. Für die Geschichte der Bundesrepublik können vor allem das katholische Milieu und das sozialdemokratische Arbeitermilieu als prägend betrachtet werden, die auch die Kernwählergruppen der beiden Volksparteien gestellt haben (Rohe 1992).

Parallelgesellschaften, ethnische Gemeinschaften oder migrantische Milieus?

description: In der deutschsprachigen Migrationsforschung wird seit langem über Begriffe für die aus Migration entstehenden sozialen Konstellationen diskutiert. Einige der Kandidaten – wie etwa die „Parallelgesellschaft“ – sind auch im öffentlichen Diskurs aufgenommen worden. Umso drängender stellen sich die Fragen nach den Implikationen der verschiedenen Begriffe und danach, welches Konzept diese Strukturen am treffendsten fasst. Der vorliegende Beitrag widmet sich dieser Diskussion und zeigt die Vorzüge wie auch die Nachteile der wichtigsten vorgeschlagenen Begriffe auf. Dabei wird für das Konzept des „migrantischen Milieus“ argumentiert. Dieses vermeidet die irreleitenden Implikationen anderer Konzepte und eignet sich deswegen am ehesten für die Beschreibung und Analyse von Migrantengruppen. Zunächst wende ich mich der Frage zu, ob es überhaupt einen Begriff für Migrantengruppen braucht – oder ob nicht die betreffenden sozialen Strukturen (auch begrifflich) in Individuen desaggregiert werden sollten (2). Anschließend werden die Begriffe der Parallelgesellschaft (3) und der ethnischen Gemeinschaft (4) diskutiert. Darauf folgt die Ausarbeitung des Begriffs des migrantischen Milieus (5), bevor ich kurz eine letzte Alternative anspreche: den Subkulturbegriff (6).

The Stability Boundary of the Distant Scattered Disk

description: The scattered disk is a vast population of trans-Neptunian minor bodies that orbit the sun on highly elongated, long-period orbits. The stability of scattered disk objects is primarily controlled by a single parameter - their perihelion distance. While the existence of a perihelion boundary that separates chaotic and regular motion of long-period orbits is well established through numerical experiments, its theoretical basis as well as its semi-major axis dependence remain poorly understood. In this work, we outline an analytical model for the dynamics of distant trans-Neptunian objects and show that the orbital architecture of the scattered disk is shaped by an infinite chain of $2:j$ resonances with Neptune. The widths of these resonances increase as the perihelion distance approaches Neptune's semi-major axis, and their overlap drives chaotic motion. Within the context of this picture, we derive an analytic criterion for instability of long-period orbits, and demonstrate that rapid dynamical chaos ensues when the perihelion drops below a critical value, given by $q_{\rm{crit}}=a_{\rm{N}}\,\big(\ln((24^2/5)\,(m_{\rm{N}}/M_{\odot})\,(a/a_{\rm{N}})^{5/2})\big)^{1/2}$. This expression constitutes a boundary between the "detached" and actively "scattering" sub-populations of distant trans-Neptunian minor bodies. Additionally, we find that within the stochastic layer, the Lyapunov time of scattered disk objects approaches the orbital period, and show that the semi-major axis diffusion coefficient is approximated by $\mathcal{D}_a\sim(8/(5\,π))\,(m_{\rm{N}}/M_{\odot})\,\sqrt{\mathcal{G}\,M_{\odot}\,a_{\rm{N}}}\,\exp\big[-(q/a_{\rm{N}})^2/2\big]$. We confirm our results with numerical simulations and highlight the connections between scattered disk dynamics and the Chirikov Standard Map. Implications of our results for the long-term evolution of the distant solar system are discussed.

description: We report on the design and commissioning of two silica aerogel Cherenkov detectors with different refractive indices. In particular, extraordinary performance in terms of the number of detected photoelectrons was achieved through an appropriate choice of PMT type and reflector, along with some design considerations. After four years of operation, the number of detected photoelectrons was found to be noticeably reduced in both detectors as a result of contamination, yellowing, of the aerogel material. Along with the details of the set-up, we illustrate the characteristics of the detectors during different time periods and the probable causes of the contamination. In particular we show that the replacement of the contaminated aerogel and parts of the reflecting material has almost restored the initial performance of the detectors.

description: We propose a Dirac-Born-Infeld (DBI) D5 vertex brane plus N_c fundamental strings configuration to describe a baryon probe in strongly coupled gauge theory with gluon condensation at finite temperature via AdS/CFT correspondence. We investigate properties of this configuration in a dilaton deformed AdS_5\times S^5 background, in which IIB string theroy is dual to super Yang-Mills thery in a state with a constant self-dual gauge field (F_{mn}=F^*_{mn}) background. We find that for most values of temperature T and gluon condensation parameter q (q = π^2), there always exists a screening length L_s. The relation L_s\sim{1\ov T} has been checked. We give the q dependence of L_s. We calculate the boost velocity v(v=-\tanhη) and angular velocity ωdependence of L_s for a baryon probe, and obtain L_s=L_0*(1-v^2)^{1/4} for large v and L_s\simω^{-1}, which are consistent with those dependence relations in the point brane plus strings case, and find that the usual relations have been modified by q. We also calculate the mass of baryon and find T dependence of baryon mass.

Space-Time Distribution of G-Band and Ca II H-Line Intensity Oscillations in Hinode/SOT-FG Observations

description: We study the space-time distributions of intensity fluctuations in 2 - 3 hour sequences of multi-spectral, high-resolution, high-cadence broad-band filtergram images (BFI) made by the SOT-FG system aboard the Hinode spacecraft. In the frequency range 5.5 < f < 8.0 mHz both G-band and Ca II H-line oscillations are suppressed in the presence of magnetic fields, but the suppression disappears for f > 10 mHz. By looking at G-band frequencies above 10 mHz we find that the oscillatory power, both at these frequencies and at lower frequencies too, lies in a mesh pattern with cell scale 2 - 3 Mm, clearly larger than normal granulation, and with correlation times on the order of hours. The mesh pattern lies in the dark lanes between stable cells found in time-integrated G-band intensity images. It also underlies part of the bright pattern in time-integrated H-line emission. This discovery may reflect dynamical constraints on the sizes of rising granular convection cells together with the turbulence created in strong intercellular downflows.

Welche Bedeutung haben soziale Milieus für den Übergang zu funktionaler Differenzierung?

description: Zahlreiche religionssoziologische und historische Arbeiten zeigen, dass sich der Katholizismus in einigen europäischen Ländern im 19. Jahrhundert zu einem konfessionellen Milieu – bzw. zu miteinander stark vernetzten Teilmilieus – verdichtete. Die Prozesse der Milieubildung liegen historisch ersichtlich parallel zu jenen der fortschreitenden gesellschaftlichen Modernisierung: Mit der Systemtheorie Luhmanns ist von einem über die Neuzeit reichenden sozialstrukturellen Umbruch zu funktionaler Primärdifferenzierung auszugehen. Im 19. und 20. Jahrhundert setzte sich die neue Differenzierungsform gesamtgesellschaftlich durch und bildete ihre bis zur Gegenwart reichenden Formen aus. Das Verhältnis der konfessionellen Milieus zu dem gleichzeitigen sozialstrukturellen Umbruch scheint allerdings nicht leicht bestimmbar zu sein: Einerseits wird die Milieubildung als Abschottung gegenüber funktionalen Ausdifferenzierungen gesehen, welche die davon negativ betroffenen Bevölkerungsgruppen vor bestimmten Effekten schützte. Im Kontrast zu dem im Protestantismus zeitgenössisch bereits deutlich spürbaren Säkularisierungstrend gelangen der katholischen Kirche zeitweise erhebliche Inklusionserfolge, insbesondere weil die konfessionell geschlossenen Milieus „tendenziell keinen Lebensbereich aussparte[n]“(Pollack 2011: 28). Trotz dieses defensiven Charakters stellen zahlreiche Publikationen andererseits die spezifisch ‚modernen‘ Merkmale heraus, insbesondere konfessionelle Vereine, Parteien, Druckmedien, Formen der schulischen Erziehung, der Massen-Religiosität. Deshalb wird der milieuförmige Katholizismus als „Antimodernismus mit modernen Mitteln“ (Altermatt 1995) interpretiert, der dazu beitrug, dass sich „die Kirche partiell modernisierte“ (Loth 1991: 11). Der milieuförmige Katholizismus reagierte zwar abgrenzend auf bestimmte Differenzierungsprozesse, begünstigte dadurch jedoch intern selbst Differenzierungsprozesse, die letztlich zur Auflösung der segmentären Abgrenzung, d. h. zur Milieu-Erosion, beitrugen.

Can solid body destruction explain abundance discrepancies in planetary nebulae?

description: In planetary nebulae, abundances of oxygen and other heavy elements derived from optical recombination lines are systematically higher than those derived from collisionally excited lines. We investigate the hypothesis that the destruction of solid bodies may produce pockets of cool, high-metallicity gas that could explain these abundance discrepancies. Under the assumption of maximally efficient radiative ablation, we derive two fundamental constraints that the solid bodies must satisfy in order that their evaporation during the planetary nebula phase should generate a high enough gas phase metallicity. A local constraint implies that the bodies must be larger than tens of meters, while a global constraint implies that the total mass of the solid body reservoir must exceed a few hundredths of a solar mass. This mass greatly exceeds the mass of any population of comets or large debris particles expected to be found orbiting evolved low- to intermediate-mass stars. We therefore conclude that contemporaneous solid body destruction cannot explain the observed abundance discrepancies in planetary nebulae. However, similar arguments applied to the sublimation of solid bodies during the preceding asymptotic giant branch (AGB) phase do not lead to such a clear-cut conclusion. In this case, the required reservoir of volatile solids is only one ten-thousandth of a solar mass, which is comparable to the most massive debris disks observed around solar-type stars, implying that this mechanism may contribute to abundance discrepancies in at least some planetary nebulae, so long as mixing of the high metallicity gas is inefficient.

The G/G/2 queue : cyclic vs. FIFS service order

description: The relative waiting times in a G/G/2 queue are investigated for FIFS vs. cyclic service order. We will prove that under the FIFS system the expected wait is shorter given rather weak conditions on the arrival process. However, the wait is not necessarily stochastically less, nor is the average wait less for every realization. This result bears on the upper limits on expected wait in a G/G/k queue given by Brumelle and Kingman.

description: In recent years, the confinement of light in open systems with no radiation leakage has raised great interest in the scientific community, both due to its peculiar and intriguing physics and due to its important technological applications. In particular, materials with near-zero permittivity offer a unique opportunity for light localization, as they enable the formation of embedded eigenstates in core-shell systems with suppressed radiation loss. For all the solutions presented thus far in the literature, the exact suppression of the radiation leakage can occur only when the size of the resonator is delicately tuned. Surprisingly, here it is shown that the tuning of the resonator radius may be unnecessary, and that nonlocal metal spherical nanostructures of any size may support multiple embedded eigenstates with a monopole-type symmetry.

description: This narrative review explores the ethical dilemmas faced by Emergency Medical Services (EMS) providers in prehospital trauma care. EMS personnel operate under high-pressure conditions, often requiring rapid decision-making that can significantly influence patient outcomes. This review synthesizes existing literature to identify common ethical challenges, including conflicts between patient autonomy and the urgency of care, issues surrounding informed consent, and the complexities of resource allocation during triage. The findings underscore the necessity of clear ethical guidelines and ongoing training to better equip EMS providers in navigating these dilemmas. The review highlights that while immediate interventions are often crucial, they may conflict with ethical principles, leading to moral distress among providers. Recommendations for future research include the development of standardized ethical frameworks, integration of ethical training in EMS education, and exploration of technological aids to support decision-making. By addressing these ethical complexities, the study aims to enhance the quality of care provided by EMS professionals, ultimately benefiting patient outcomes and provider well-being.

description: We report five new measurements of central black hole masses based on STIS and WFPC2 observations with the Hubble Space Telescope and on axisymmetric, three-integral, Schwarzschild orbit-library kinematic models. We selected a sample of galaxies within a narrow range in velocity dispersion that cover a range of galaxy parameters (including Hubble type and core/power-law surface density profile) where we expected to be able to resolve the galaxy's sphere of influence based on the predicted value of the black hole mass from the M-sigma relation. We find masses in units of 10^8 solar masses for the following galaxies: NGC 3585, M_BH = 3.4 (+1.5, -0.6); NGC 3607, M_BH = 1.2 (+0.4, -0.4); NGC 4026, M_BH = 2.1 (+0.7, -0.4); and NGC 5576, M_BH = 1.8 (+0.3, -0.4), all significantly excluding M_BH = 0. For NGC 3945, M_BH = 0.09 (+0.17, -0.21), which is significantly below predictions from M-sigma and M-L relations and consistent with M_BH = 0, though the presence of a double bar in this galaxy may present problems for our axisymmetric code.

description: Der Milieubegriff startet ambitioniert. Bei Emile Durkheim, im Behavorismus und in der Phänomenologie der 1920er und 1930er Jahre wird er in verschiedenen Kontexten als philosophischer und sozialwissenschaftlicher Grundlagenbegriff erprobt. Das Verhältnis von „Individuum und Gesellschaft“ von „Anlage und Umwelt“ soll mit ihm aufgeklärt werden. Damit hat man die Milieukategorie wohl überlastet, und es finden sich heute kaum noch grundlagentheoretische Ansprüche an diesen Begriff. Er ist eine Vergesellschaftungsform neben anderen, aber nicht ein Begriff, der Aufschluss über Sozialität an sich gibt.1 Aus dem differenzierungstheoretischen Traditionsstrang ist er ganz verschwunden. Während ihm Durkheim (1980: 194 ff.) noch eine Schlüsselstellung einräumt, sucht man ihn im Begriffsrepertoire der neueren Systemtheorie vergeblich. Das Soziale steht in einem Umweltverhältnis zum Individuum, und hierzu passt nicht die Annahme seiner ‚psychologisch tief verankerten Prägung‘ (Hradil 2006: 199) durch milieuspezifischen Habitus und Mentalität.

description: The flux of angular momentum of electromagnetic field of an arbitrarily moving point charge is investigated. General equations are obtained for the transfer of angular momentum at arbitrary distance from the charge, and corresponding equations in the far-field approximation. An explicit expression is obtained for the flux of angular momentum in the wave zone in terms of coordinates, velocity, and acceleration of the charge. The torque is calculated, that would act on an object if it absorbed all the radiation incident on it. It is shown that this torque is proportional to the curl of the stress tensor of the electromagnetic field; in the far field approximation the torque is proportional to the curl of the Poynting vector.

description: In unseren Feldforschungen zu „Religionshybriden“ untersuchen wir das Handeln und die kulturellen Ausdrucksformen von Menschen an symbolischen Orten wie z.B. Kirchen und Kirchenruinen, mehr oder weniger gut sanierten Gutshäusern und in sogenannten „alternativen Gemeinschaften“ 2. Wir können dabei auch im ländlichen Raum milieuähnliche Strukturen mit kulturkreativem „Touch“ entdecken, wie sie sonst nur im „urbanen Milieu“ (vgl. Merkel 2009) großer Städte vermutet werden.

description: We present an analysis of the structures, sizes, star formation rates, and local environmental properties of galaxies at z~4-6, utilising deep Hubble Space Telescope imaging of the Hubble Ultra Deep Field. The galaxies we study are selected with the Lyman-break drop-out technique, using galaxies which are B-,V-, and i-drops, which effectively selects UV bright starbursting galaxies between z=4 and z=6. Our primary observational finding is that starbursting galaxies at z>4 have a diversity in structure, with roughly 30% appearing distorted and asymmetric, while the majority are smooth and apparently undisturbed systems. We utilize several methods to compute the inferred assembly rates for these distorted early galaxies including utilising the CAS system and pair counts. Overall, we find a similar fraction of galaxies which are in pairs as the fraction which have a distorted structure. Using the CAS methodology, and our best-estimate for merger time-scales, we find that the total number of inferred effective mergers for M_{*} > 10^9-10 M_sol galaxies at z<6 is N_m = 4.2^{+4.1}_{-1.4}. The more common symmetrical systems display a remarkable scaling relation between the concentration of light and their half-light radii, revealing the earliest known galaxy scaling relationship, and demonstrating that some galaxies at z>4 are likely in a relaxed state. Systems which are asymmetric do not display a correlation between size and half-light radii, and are generally larger than the symmetric smooth systems. The time-scale for the formation of these smooth systems is 0.5-1 Gyr, suggesting that most of these galaxies are formed through coordinated very rapid gas collapses and star formation over a size of 1-2 kpc, or from merger events at z > 10.

Formierung und Gestaltung sozialer Milieus: eine sozialisationstheoretische Perspektive

description: Im Vergleich zu makrostrukturellen Organisationsprinzipien, die durch soziale Zuschreibungen wie z. B. Nationalität, Klassenzugehörigkeit, ethnische Zugehörigkeit oder Einbindungen in institutionelle Settings wie etwa das Bildungssystem markiert werden, konstituieren sich soziale Milieus aus sozialisationstheoretischer Perspektive zunächst in kleinräumig geformten Handlungszusammenhängen. Gleichwohl finden im Gefüge der Gesamtgesellschaft höchst unterschiedliche Milieuformierungen ihren Ausdruck, die auf unterschiedlichen Handlungsebenen angesiedelt sind. In allen Fällen jedoch zeichnet soziale Milieus aus, dass sie nicht auf sozialen Zuschreibungs- und Ordnungskriterien beruhen, sondern auf konjunkten Handlungspraktiken und Sinnzusammenhängen. Sie stellen, mit Goffman (1971) gesprochen, eine Interaktionsordnung her, die Handlungsskripte bereithält und die Akteure mit einer sozialen Handlungsgrammatik samt solchen Vollzugsanweisungen ausstattet, die ihren Lebensverhältnissen angemessen sind (Grundmann/Steinhoff 2014). Diese Skripte und Handlungsgrammatiken verweisen auf ein konkretes lebensweltliches Miteinander, das nun seinerseits den Handlungsrahmen absteckt, vor dessen Hintergrund sich die Konturen des Seins herausbilden und entwickeln.

Il rapporto tra azione causale ed azione cartolare

description: Il presente lavoro affronta la questione del rapporto tra l’azione cartolare e l’azione causale nell’ambito dei titoli cambiari; nonché il problema della relazione, di diritto sostanziale, che intercorre tra i menzionati titoli ed i rapporti causali che soggiacciono alla loro emissione e circolazione; con costante riferimento sia al diritto italiano che al diritto paraguaiano.
Vengono così analizzati i concetti tradizionali della causa della cambiale e della convenzione esecutiva, per poi passare alla analisi della funzione economica tipica dei titoli cambiari e, segnatamente, la previsione del loro rilascio o negoziazione nell’economia del rapporto fondamentale. Si affrontano, così, i noti problemi della novazione e della dazione in pagamento attuate mediante questi titoli, tenendo in particolare considerazione anche la struttura delegatoria che presentano alcuni di essi.
Particolare attenzione viene dedicata al fatto che, nella maggior parte dei casi, le parti non prevedono specificamente l’incidenza del rilascio o girata del titolo cambiario sul rapporto sottostante. Per questa ragione, si mette in luce che nella maggior parte dei casi la fattispecie configura una modificazione della relazione causale intercorrente tra le parti, proprio per l’assenza di pattuizione espressa al riguardo. Strettamente connesso con quest’aspetto risulta l’esame dell’emissione dei titoli cambiari solvendi causa, problematica nell’ambito della quale non si è mancato di tener conto della disciplina antiriciclaggio e dei moderni contributi dottrinari sull’oggetto dell’obbligazione pecuniaria.
Viene, infine, vagliata anche l’incidenza dell’ulteriore circolazione del titolo sul rapporto causale che giustifica il suo possesso da parte del girante; per poi passare, come conclusione del lavoro, a stabilire l’interpretazione non solo processuale ma anche sostanziale che deve darsi, alla luce dei risultati raggiunti, alla disciplina degli artt. 66 della legge cambiaria e 58 della legge assegni.

description: Vor dreißig Jahren haben Anne Honer und ich einige terminologische Vorschläge zur theoretischen Verständigung über die Phänomene Lebenswelt, Milieu und Situation gemacht, die dann 1984 in der damals noch von René König herausgegebenen Kölner Zeitschrift für Soziologie und Sozialpsychologie veröffentlicht worden sind (vgl. Hitzler/Honer 1984). Danach haben wir uns zwar immer wieder mit Lebenswelt und Situation, mit Milieu theoretisch hingegen gar nicht mehr und empirisch eher unreflektiert befasst. Im Folgenden denke ich über Milieu vor allem vor dem Hintergrund posttraditionaler Vergemeinschaftung und im Verhältnis zum Phänomen des Mindsets nach. Und der materiale Gegenstand meiner Überlegungen stammt aus einem größeren Forschungszusammenhang, auf den ich mich seit 2009 konzentriert habe (vgl. Hitzler 2010 a, 2012 a und 2012 b; Hitzler/ Grewe 2011; Hitzler/Mücher 2012).

Recent HBT results in Au+Au and p+p collisions from PHENIX

description: We present Hanbury-Brown Twiss measurements from the PHENIX experiment at RHIC for final results for charged kaon pairs from sqrt{s_{NN}} = 200 GeV Au+Au collisions and preliminary results for charged pion pairs from sqrt{s} = 200 GeV p+p collisions. We find that for kaon pairs from Au+Au, each traditional 3D Gaussian radius shows approximately the same linear increase as a function of N^{1/3}_{part}. An imaging analysis reveals a significant non-Gaussian tail for r \gtrsim 10 fm. The presence of a tail for kaon pairs demonstrates that similar non-Gaussian tails observed in earlier pion measurements cannot be fully explained by decays of long-lived resonances. The preliminary analysis of pions from sqrt{s} = 200 GeV p+p minimum biased collisions show correlations which are well suited to traditional 3D HBT radii extraction via the Bowler-Sinyukov method, and we present R_out, R_side, and R_long as a function of mean transverse pair mass.

description: Bald patch (BP) is a magnetic topological feature where U-shaped field lines turn tangent to the photosphere. Field lines threading the BP trace a separatrix surface where reconnection preferentially occurs. Here we study the evolution of multiple, strong-field BPs in active region 12673 during the most intense, X9.3 flare of solar cycle 24. The central BP, located between the initial flare ribbons, largely "disintegrated" within 35 minutes. The more remote, southern BP survived. The disintegration manifested as a 9-degree rotation of the median shear angle; the perpendicular component of the horizontal field (with respect to the polarity inversion line) changed sign. The parallel component exhibited a step-wise, permanent increase of 1 kG, consistent with previous observations of the flare-related "magnetic imprint". The observations suggest that magnetic reconnection during a major eruption may involve entire BP separatrices, leading to a change of magnetic topology from BPs to sheared arcades.
