description: Secondary HIV prevention, or "positive prevention," is concerned with reducing HIV transmission risk behavior and optimizing the health and quality of life of people living with HIV/AIDS (PLWHA). The association between mental health and HIV transmission risk (i.e., sexual risk and poor medication adherence) is well established, although most of this evidence is observational. Further, a number of efficacious mental health treatments are available for PLWHA yet few positive prevention interventions integrate mental health treatment. We propose that mental health treatment, including behavioral and pharmacologic interventions, can lead to reductions in HIV transmission risk behavior and should be a core component of secondary HIV prevention. We present a conceptual model and recommendations to guide future research on the effect of mental health treatment on HIV transmission risk behavior among PLWHA.

description: The thermal Bogoliubov transformation in thermo field dynamics is generalized in two respects. First, a generalization of the $α$--degree of freedom to tilde non--conserving representations is considered. Secondly, the usual $2\times2$ Bogoliubov matrix is extended to a $4\times4$ matrix including mixing of modes with non--trivial multiparticle correlations. The analysis is carried out for both bosons and fermions.

description: Background: Leaders are struggling to care for the estimated 143,000,000 orphans and millions more abandoned children worldwide. Global policy makers are advocating that institution-living orphans and abandoned children (OAC) be moved as quickly as possible to a residential family setting and that institutional care be used as a last resort. This analysis tests the hypothesis that institutional care for OAC aged 6-12 is associated with worse health and wellbeing than community residential care using conservative two-tail tests. Methodology: The Positive Outcomes for Orphans (POFO) study employed two-stage random sampling survey methodology in 6 sites across 5 countries to identify 1,357 institution-living and 1,480 community-living OAC ages 6-12, 658 of whom were double-orphans or abandoned by both biological parents. Survey analytic techniques were used to compare cognitive functioning, emotion, behavior, physical health, and growth. Linear mixed-effects models were used to estimate the proportion of variability in child outcomes attributable to the study site, care setting, and child levels and institutional versus community care settings. Conservative analyses limited the community living children to doubleorphans or abandoned children. Principal Findings: Health, emotional and cognitive functioning, and physical growth were no worse for institution-living than community-living OAC, and generally better than for community-living OAC cared for by persons other than a biological parent. Differences between study sites explained 2-23% of the total variability in child outcomes, while differences between care settings within sites explained 8-21%. Differences among children within care settings explained 64-87%. After adjusting for sites, age, and gender, institution vs. community-living explained only 0.3-7% of the variability in child outcomes. Conclusion: This study does not support the hypothesis that institutional care is systematically associated with poorer wellbeing than community care for OAC aged 6-12 in those countries facing the greatest OAC burden. Much greater variability among children within care settings was observed than among care settings type. Methodologically rigorous studies must be conducted in those countries facing the new OAC epidemic in order to understand which characteristics of care promote child wellbeing. Such characteristics may transcend the structural definitions of institutions or family homes.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Heavy inertial particles in turbulent flows gain energy slowly but lose it rapidly

description: We present an extensive numerical study of the time irreversibility of the dynamics of heavy inertial particles in three-dimensional, statistically homogeneous and isotropic turbulent flows. We show that the probability density function (PDF) of the increment, $W(τ)$, of a particle's energy over a time-scale $τ$ is non-Gaussian, and skewed towards negative values. This implies that, on average, particles gain energy over a period of time that is longer than the duration over which they lose energy. We call this $\textit{slow gain}$ and $\textit{fast loss}$. We find that the third moment of $W(τ)$ scales as $τ^3$, for small values of $τ$. We show that the PDF of power-input $p$ is negatively skewed too; we use this skewness ${\rm Ir}$ as a measure of the time-irreversibility and we demonstrate that it increases sharply with the Stokes number ${\rm St}$, for small ${\rm St}$; this increase slows down at ${\rm St} \simeq 1$. Furthermore, we obtain the PDFs of $t^+$ and $t^-$, the times over which $p$ has, respectively, positive or negative signs, i.e., the particle gains or loses energy. We obtain from these PDFs a direct and natural quantification of the the slow-gain and fast-loss of the particles, because these PDFs possess exponential tails, whence we infer the characteristic loss and gain times $t_{\rm loss}$ and $t_{\rm gain}$, respectively; and we obtain $t_{\rm loss} < t_{\rm gain}$, for all the cases we have considered. Finally, we show that the slow-gain in energy of the particles is equally likely in vortical or strain-dominated regions of the flow; in contrast, the fast-loss of energy occurs with greater probability in the latter than in the former.

description: In the era of life-prolonging antiretroviral therapy, chronic fatigue is one of the most prevalent and disabling symptoms of people living with HIV/AIDS, yet its measurement remains challenging. No instruments have been developed specifically to describe HIV-related fatigue. We assessed the reliability and construct validity of the HIV-Related Fatigue Scale (HRFS), a 56-item self-report instrument developed through formative qualitative research and designed to measure the intensity and consequences of fatigue as well as the circumstances surrounding fatigue in people living with HIV. The HRFS has three main scales, which measure fatigue intensity, the responsiveness of fatigue to circumstances and fatigue-related impairment of functioning. The functioning scale can be further divided into subscales measuring impairment of activities of daily living, impairment of mental functioning and impairment of social functioning. Each scale demonstrated high internal consistency (Cronbach's alpha=0.93, 0.91 and 0.97 for the intensity, responsiveness and functioning scales, respectively). The HRFS scales also demonstrated satisfactory convergent validity when compared to other fatigue measures. HIV-Related Fatigue Scales were moderately correlated with quality of nighttime sleep (rho=0.46, 0.47 and 0.35) but showed only weak correlations with daytime sleepiness (rho=0.20, 0.33 and 0.18). The scales were also moderately correlated with general mental and physical health as measured by the SF-36 Health Survey (rho ranged from 0.30 to 0.68 across the 8 SF-36 subscales with most >0.40). The HRFS is a promising tool to help facilitate research on the prevalence, etiology and consequences of fatigue in people living with HIV.
Retardation effects in the Holstein-Hubbard chain at half-filling

description: The ground state phase diagram of the half-filled one-dimensional Holstein-Hubbard model contains a charge-density-wave (CDW) phase, driven by the electron-phonon (e-ph) coupling, and a spin-density-wave (SDW) phase, driven by the on-site electron-electron (e-e) repulsion. Recently, the existence of a third phase, which is metallic and lies in a finite region of parameter space between these two gapped phases, has been claimed. We study this claim using a renormalization-group method for interacting electrons that has been extended to include also e-ph couplings. Our method treats e-e and e-ph interactions on an equal footing and takes retardation effects fully into account. We find a direct transition between the spin- and charge-density wave states. We study the effects of retardation, which are particularly important near the transition, and find that Umklapp processes at finite frequencies drive the CDW instability close to the transition. We also perform determinantal quantum Monte Carlo calculations of correlation functions to confirm our results for the phase diagram.

description: Rapid human immunodeficiency virus (HIV) antibody tests support the effort to expand access to HIV testing and counseling services in remote, rural, and poor parts of the world. We validated the Capillus HIV-1/HIV-2 (Trinity Biotech PLC, Bray, County Wicklow, Ireland) and Determine HIV-1/2 (Abbott Laboratories, Abbott Park, IL) rapid tests in a reference laboratory using patient samples from Tanzania and evaluated the performance of the tests under field conditions in northern Tanzania. We used the resulting data to study sequential and parallel testing algorithms. In the validation study, sensitivity, specificity, the predictive value of a positive test (PV+), and the predictive value of a negative test (PV-) were all 100% for Capillus and Determine. In the field evaluation among 12,737 clients, sensitivity, specificity, PV+, and PV- were 99.7%, 99.8%, 98.7%, and 99.9%, respectively, for Capillus and 99.6%, 99.9%, 99.5%, and 99.9%, respectively, for Determine. A sequential testing algorithm that did not confirm a negative initial Capillus result with a Determine result cost $7.77 per HIV diagnosis but missed 0.3% of HIV infections. A sequential testing algorithm that did not confirm a negative initial Determine result with a Capillus result cost $7.64 per HIV diagnosis but missed 0.4% of HIV infections. A parallel testing algorithm cost $13.46 per HIV diagnosis but detected more HIV-infected clients.

description: The extragalactic background radiation produced by distant galaxies emitting in the far infrared limits the sensitivity of telescopes operating in this range due to confusion. We have constructed a model of the infrared background based on numerical simulations of the large-scale structure of the Universe and the evolution of dark matter halos. The predictions of this model agree well with the existing data on source counts. We have constructed maps of a sky field with an area of 1 deg$^2$ directly from our simulated observations and measured the confusion limit. At wavelengths $100-300$ $μ$m the confusion limit for a 10-m telescope has been shown to be at least an order of magnitude lower than that for a 3.5-m one. A spectral analysis of the simulated infrared background maps clearly reveals the large-scale structure of the Universe. The two-dimensional power spectrum of these maps has turned out to be close to that measured by space observatories in the infrared. However, the fluctuations in the number of intensity peaks observed in the simulated field show no clear correlation with superclusters of galaxies; the large-scale structure has virtually no effect on the confusion limit.

description: Die in dieser Veröffentlichung dargestellten fachdidaktischen Profile Forschenden Lernens (FLs) wurden anhand von Leitfragen entwickelt, welche die am Cluster beteiligten Fächer in Workshops gemeinsam erarbeitet haben. Ziel war es, Gemeinsamkeiten und Spezifika der Zugänge zum FL auszuloten. Neben den zu erwartenden Unterschieden zeigten sich auch eine Reihe von Überschneidungen und Verknüpfungsmöglichkeiten zwischen den fachdidaktischen Ansätzen FLs. So werden in den Profilen als bevorzugte Forschungskontexte die Wirkungsforschung, die wissenschaftliche Begleitforschung und empirisch ausgerichtete Qualifikationsarbeiten in den Studiengängen genannt. Hinsichtlich der Bereiche, in denen das FL eine besondere Wirksamkeit entfalten kann, wird auf den Abgleich von Theorie und Praxis, auf das theoriebasierte Reflektieren, auf die Entwicklung eines forschenden Habitus und auf die Ausbildung von Professionalität verwiesen. Eine Reihe von Fachdidaktiken hebt dabei die Notwendigkeit hervor, das Verhältnis von Theorie und Praxis wahrzunehmen und zu reflektieren. Vielfach werden problem- und studierendenzentrierte Ansätze verfolgt. Häufig wird das FL auch mit dem Durchlaufen der wesentlichen Schritte eines Forschungsprozesses identifiziert. Die Fachdidaktiken begründen ihre Ansätze mit Verweis auf einschlägige didaktische Fachliteratur und wissenschaftliche Veröffentlichungen angrenzender Fächer. Die Mehrzahl der Fachdidaktiken verortet sich zudem in spezifischen Theorierahmen. Es kann festgehalten werden, dass Synergien zwischen den Fachdidaktiken vor allem dort entstehen, wo es um die Anbahnung eines kritisch-reflexiven Habitus und einer anwendungsbezogenen Forschungskompetenz geht. Hinsichtlich der praktischen Umsetzung FLs im Praxissemester wird auf konkrete Arbeitshilfen sowie Angebote im Bereich Fortbildung und Beratung verwiesen. Vereinzelt wird auch auf gemeinsame Forschungsperspektiven Bezug genommen. So wird angeregt, sowohl domänenspezifische als auch domänenübergreifende Lehr-/Lern- und Forschungsbündnisse zu bilden.

description: We present time-resolved optical spectroscopy of the afterglows of the gamma-ray bursts GRB 990510 and GRB 990712. Through the identification of several absorption lines in the first epoch GRB 990510 spectrum, we determine the redshift for this burst at z >= 1.619. No clear emission lines are detected. The strength of the MgI feature is indicative of a dense environment, most likely the host galaxy of GRB 990510. Although the host is extremely faint (V >~ 28), the GRB afterglow allows us to probe its interstellar medium and - in principle - to measure its metallicity. The optical spectrum of GRB 990712 (whose host galaxy is the brightest of the known GRB hosts at cosmological redshifts), shows clear features both in emission and absorption, at a redshift of z = 0.4331 +/- 0.0004. On the basis of several line emission diagnostic diagrams, we conclude that the host galaxy of GRB 990712 is most likely an HII galaxy. We derive a unreddened [OII] star formation rate of 2.7 +/- 0.8 Msun/yr. Correcting for the measured extinction intrinsic to the host galaxy (A(V) = \gpm{3.4}{2.4}{1.7}), this value increases to \gpm{35}{178}{25} Msun/yr. The [OII] equivalent width, compared to that of field galaxies at z <= 1, also suggests that the host of GRB 990712 is vigorously forming stars. We employ the oxygen and Hbeta emission-line intensities to estimate the global oxygen abundance for the host of GRB 990712: log(O/H) = -3.7 +- 0.4, which is slightly below the lowest metallicity one finds in nearby spiral galaxies. For both GRBs we study the time evolution of the absorption lines, whose equivalent width might be expected to change with time if the burst resides in a dense compact medium. We find no evidence for a significant change in the MgII width.

description: We investigate the electric quadrupole interaction of an alkali-metal atom with guided light in the fundamental and higher-order modes of a vacuum-clad ultrathin optical fiber. We calculate the quadrupole Rabi frequency, the quadrupole oscillator strength, and their enhancement factors. In the example of a rubidium-87 atom, we study the dependencies of the quadrupole Rabi frequency on the quantum numbers of the transition, the mode type, the phase circulation direction, the propagation direction, the orientation of the quantization axis, the position of the atom, and the fiber radius. We find that the root-mean-square (rms) quadrupole Rabi frequency reduces quickly but the quadrupole oscillator strength varies slowly with increasing radial distance. We show that the enhancement factors of the rms Rabi frequency and the oscillator strength do not depend on any characteristics of the internal atomic states except for the atomic transition frequency. The enhancement factor of the oscillator strength can be significant even when the atom is far away from the fiber. We show that, in the case where the atom is positioned on the fiber surface, the oscillator strength for the quasicircularly polarized fundamental mode HE$_{11}$ has a local minimum at the fiber radius $a\simeq 107$ nm, and is larger than that for quasicircularly polarized higher-order hybrid modes, TE modes, and TM modes in the region $a<498.2$ nm.

description: In this study, we report about the occurrence of phase separation through spinodal decomposition (SD) in spinel manganese ferrite (Mn ferrite) thin films grown by Dynamic Aurora pulsed laser deposition. The driving force behind this SD in Mn ferrite films is considered to be an ion-impingement-enhanced diffusion that is induced by the application of magnetic field during film growth. The phase separation to Mn-rich and Fe-rich phases in Mn ferrite films is confirmed from the Bragg’s peak splitting and the appearance of the patterned checkerboard-like domain in the surface. In the cross-sectional microstructure analysis, the distribution of Mn and Fe-signals alternately changes along the lateral (x and y) directions, while it is almost homogeneous in the z-direction. The result suggests that columnar-type phase separation occurs by the up-hill diffusion only along the in-plane directions. The propagation of a quasi-sinusoidal compositional wave in the lateral directions is confirmed from spatially resolved chemical composition analysis, which strongly demonstrates the occurrence of phase separation via SD. It is also found that the composition of Mn-rich and Fe-rich phases in phase-separated Mn ferrite thin films deposited at higher growth temperature and in situ magnetic field does not depend on the corresponding average film composition.

description: Forschendes Lernen kann in zahlreichen Kontexten stattfinden; im jetzigen Lehramtsstudium eignet sich dafür aber besonders der Zeitpunkt des Praxissemesters. Dies bietet sowohl die Möglichkeit, sich selbst als Lehrperson auszuprobieren, als auch, erste Erfahrungen mit der Reflexion von Unterricht zu sammeln, was idealerweise an selbst durchgeführten Stunden geschehen sollte. Erwachsen aus der Unterrichtsplanung, -durchführung und -reflexion weiterreichende Untersuchungen, die die Studierenden in ihrer Lehrerprofessionalisierung unterstützen, wurde das Konzept erfolgreich umgesetzt. Zwei Beispiele sollen im folgenden Beitrag aufzeigen, wie die Lehramtsausbildung das Forschende Lernen in der Biologiedidaktik an der Universität Bielefeld realisiert.

description: We present a map of the near subsurface hydrogen distribution on Mars, based on epithermal neutron data from the Mars Odyssey Neutron Spectrometer. The map's spatial resolution is approximately improved two-fold via a new form of the pixon image reconstruction technique. We discover hydrogen-rich mineralogy far from the poles, including ~10 wt. % water equivalent hydrogen (WEH) on the flanks of the Tharsis Montes and greater than 40 wt. % WEH at the Medusae Fossae Formation (MFF). The high WEH abundance at the MFF implies the presence of bulk water ice. This supports the hypothesis of recent periods of high orbital obliquity during which water ice was stable on the surface. We find the young undivided channel system material in southern Elysium Planitia to be distinct from its surroundings and exceptionally dry; there is no evidence of hydration at the location in Elysium Planitia suggested to contain a buried water ice sea. Finally, we find that the sites of recurring slope lineae (RSL) do not correlate with subsurface hydration. This implies that RSL are not fed by large, near-subsurface aquifers, but are instead the result of either small (less than 120 km diameter) aquifers, deliquescence of perchlorate and chlorate salts or dry, granular flows.

description: Ausgehend von als noch nicht weitreichend genug empfundenen Transferaktivitäten am Oberstufen-Kolleg im Anschluss an Forschungs- und Entwicklungsprojekte (FEP) wird im vorliegenden Beitrag die Frage nach dem Zusammenhang von Forschungs- und Entwicklungsaktivitäten einerseits und deren systematischem Nexus zur organisationsbasierten Schulentwicklung (SE) andererseits gestellt. Vor dem Hintergrund einer Defizitdiagnose herkömmlicher Schulentwicklungsmodelle erfolgt ein Plädoyer für eine „professionssensible Schulentwicklung“ sowie anhand des daraus resultierenden Konzepts einer individualisierten Schulentwicklungsarbeit das Programm eines neuen FEP-SE-Transfermodells, das am Oberstufen-Kolleg nunmehr erprobt und evaluiert wird. Based on transfer activities at the Oberstufen-Kolleg following research and development projects (FEP), which are perceived as not yet far-reaching enough concerning the school development, this article raises the question of the connection between research and development activities on the one hand and their systematic nexus to organization-based school development (SE) on the other. Against the background of a deficit diagnosis of conventional school development models, there is a plea for a “profession-sensitive school development” and, on the basis of the resulting concept of individualized school development work, the program of a new FEP-SE transfer model, which is now being tested and evaluated at the Oberstufen-Kolleg.

Renormalization Group Approach to Matrix Models in Two-Dimensional Quantum Gravity

description: We explore the implications of recent work by Brézin and Zinn-Justin, applying the renormalization group techniques from critical phenomena to the scaling limit of matrix models in two-dimensional quantum gravity. They endeavor to get the lowest order fixed points of the theory giving insight upon the critical points of the theory. We show that at leading order the perturbative result is equal to the saddle-point approximation result. We calculate the next-to-leading order in the perturbative expansion exploring the goodness of the approach.

description: Der vorliegende Beitrag dokumentiert den diesjährigen Forschungs- und Entwicklungsplan. Die aktuellen Änderungen von Konzepten werden unter Rückgriff auf die Ausdifferenzierung der Typik von Forschung und Entwicklung diskutiert, die der in diesem Jahr verstorbene ehemalige Leiter der Wissenschaftlichen Einrichtung des Oberstufen-Kollegs, Ludwig Huber, vor fünfzehn Jahren für Lehrer*innenforschung beschrieben hat. Neben den am Oberstufen-Kolleg projektförmig und im multiprofessionellen Team organisierten Forschungs- und Entwicklungsprojekten zählen nach Huber auch die Reflexion und Produktion für die Praxis, die Verbreitung, der Austausch sowie die Umsetzung (Dissemination und Implementation) hierzu. Der Beitrag dokumentiert die Einrichtung neuer Disseminationsstrategien durch Online-Journale sowie mehrere neue Netzwerke und Forschungskooperationen. This article documents this year’s research and development plan. The current changes in concepts are discussed with reference to the differentiation of the typology of research and development described fifteen years ago by Ludwig Huber, former head of the Action Research Department of the Oberstufen-Kolleg, who died this year. In addition to the research and development organized as projects in a multi-professional team at the Oberstufen-Kolleg, according to Huber this also includes reflection and production for practice, distribution, exchange as well as realization (dissemination and implementation). The article documents the establishment of new dissemination strategies through online journals as well as several new networks and research cooperations.

Underdoped cuprates phenomenology in the 2D Hubbard model within COM(SCBA)

description: The two-dimensional Hubbard model is studied within the Composite Operator Method (COM) with the residual self-energy computed in the Self-Consistent Born Approximation (SCBA). COM describes interacting electrons in terms of the new elementary excitations appearing in the system owing to strong correlations; residual interactions among these excitations are treated within the SCBA. The anomalous features appearing in the spectral function A(k,ω), the momentum distribution function n(k) and the Fermi surface are analyzed for various values of the filling (from overdoped to underdoped region) in the intermediate coupling regime at low temperatures. For low doping, in contrast with the ordinary Fermi-liquid behavior of a weakly-correlated metal found at high doping, we report the opening of a pseudogap and some non-Fermi-liquid features as measured for cuprates superconductors. In addition, we show the presence of kinks in the calculated electronic dispersion in agreement with ARPES data.
