The Interdependence of Pulmonary Structure and Function: A Synopsis

It is a great pleasure to participate in the 1964 Stoneburner lectures and to present some recent views on the structure and function of the lung. In this report I will give a brief summary and show you three pictures to indicate some of the inter-relationships that exist

Fachspezifisches Unterrichtscoaching im Praktikum: Eine quasi-experimentelle Interventionsstudie

Zusammenfassung: Wiederholt wurde gezeigt, dass Unterrichtspraktika von Lehramtsstudierenden sehr geschätzt werden. Allerdings wissen wir wenig über die Wirkung unterschiedlicher Unterstützungsformen in Praktika auf das Lernen zukünftiger Lehrpersonen. Ein Modell zur Förderung von Praktikanten ist das fachspezifische Unterrichtscoaching. In einer quasi-experimentellen Interventionsstudie wurde dessen Wirksamkeit basierend auf Fragebogen, Videoaufzeichnungen und Interviews mit Dyaden von Praxislehrpersonen und ihren Praktikanten untersucht. Ergebnisse der Studie zeigen, dass in fachspezifischem Unterrichtscoaching weitergebildete Praxislehrpersonen (Interventionsgruppe, NIG = 16) wesentliche Elemente dieses Modells in ihr Handlungsrepertoire aufnahmen. Ihre Unterstützungspraxis unterscheidet sich signifikant von jener der Kontrollgruppe (NKG = 16), welche die Praktikanten auf traditionelle Weise unterstützen. Indikatoren für Lernen im Kontext von Unterrichtsbesprechungen belegen weiter, dass die Praktikanten der Interventionsgruppe signifikant mehr Lernerträge erzielten als die traditionell unterstützten Praktikanten. Auch die anhand von Videoaufnahmen vorgenommene Einschätzung der Unterrichtsqualität fiel für die Interventionsgruppe signifikant besser aus als für die Kontrollgrupp

Lepton flavor violation in low-scale seesaw models: SUSY and non-SUSY contributions

Taking the supersymmetric inverse seesaw mechanism as the explanation for neutrino oscillation data, we investigate charged lepton flavor violation in radiative and 3-body lepton decays as well as in neutrinoless $\mu-e$ conversion in muonic atoms. In contrast to former studies, we take into account all possible contributions: supersymmetric as well as non-supersymmetric. We take CMSSM-like boundary conditions for the soft supersymmetry breaking parameters. We find several regions where cancellations between various contributions exist, reducing the lepton flavor violating rates by an order of magnitude compared to the case where only the dominant contribution is taken into account. This is in particular important for the correct interpretation of existing data as well as for estimating the reach of near future experiments where the sensitivity will be improved by one to two orders of magnitude. Moreover, we demonstrate that ratios like BR($\tau\to 3 \mu$)/BR($\tau\to \mu e^+ e^-$) can be used to determine whether the supersymmetric contributions dominate over the $W^\pm$ and $H^\pm$ contributions or vice versa.Comment: 75 pages, 7 figures. v3: references and comments added.

Building capacity for dissemination and implementation research: One university’s experience

Abstract Background While dissemination and implementation (D&I) science has grown rapidly, there is an ongoing need to understand how to build and sustain capacity in individuals and institutions conducting research. There are three inter-related domains for capacity building: people, settings, and activities. Since 2008, Washington University in St. Louis has dedicated significant attention and resources toward building D&I research capacity. This paper describes our process, challenges, and lessons with the goal of informing others who may have similar aims at their own institution. Activities An informal collaborative, the Washington University Network for Dissemination and Implementation Research (WUNDIR), began with a small group and now has 49 regular members. Attendees represent a wide variety of settings and content areas and meet every 6 weeks for half-day sessions. A logic model organizes WUNDIR inputs, activities, and outcomes. A mixed-methods evaluation showed that the network has led to new professional connections and enhanced skills (e.g., grant and publication development). As one of four, ongoing, formal programs, the Dissemination and Implementation Research Core (DIRC) was our first major component of D&I infrastructure. DIRC’s mission is to accelerate the public health impact of clinical and health services research by increasing the engagement of investigators in later stages of translational research. The aims of DIRC are to advance D&I science and to develop and equip researchers with tools for D&I research. As a second formal component, the Washington University Institute for Public Health has provided significant support for D&I research through pilot projects and a small grants program. In a third set of formal programs, two R25 training grants (one in mental health and one in cancer) support post-doctoral scholars for intensive training and mentoring in D&I science. Finally, our team coordinates closely with D&I functions within research centers across the university. We share a series of challenges and potential solutions. Conclusion Our experience in developing D&I research at Washington University in St. Louis shows how significant capacity can be built in a relatively short period of time. Many of our ideas and ingredients for success can be replicated, tailored, and improved upon by others

The model of stationary random process is used for the analysis. The coordination spectral of the characteristics infrasound and seismic activity are shown for the given period of time. The analysis of researches shows change of a spectrum infrasound before earthquake

A Resonant soft x-ray powder diffraction study to determine the orbital ordering in A-site ordered SmBaMn2O6

Soft X-ray resonant powder diffraction has been performed at the Mn L2,3 edges of A-site ordered SmBaMn2O6. The energy and polarization dependence of the (1/2 1/2 0) reflection provide direct evidence for a (x2-z2)/(y2-z2) type orbital ordering in contrast to the single layer manganite. The temperature dependence of the reflection indicates an orbital reorientation transition at 210 K, below which the charge and orbital ordered MnO2 sheets show AAAA type of stacking. The concurring reduction of the ferromagnetic super exchange correlations leads to further charge localization
