Productivity in Higher Education/ Kevin Stange, Kevin Strange, Caroline M. Hoxby.
No full textIn English.How do the benefits of higher education compare with its costs, and how does this comparison vary across individuals and institutions? These questions are fundamental to quantifying the productivity of the education sector. The studies in Productivity in Higher Education use rich and novel administrative data, modern econometric methods, and careful institutional analysis to explore productivity issues. The authors examine the returns to undergraduate education, differences in costs by major, the productivity of for-profit schools, the productivity of various types of faculty and of outcomes, the effects of online education on the higher education market, and the ways in which the productivity of different institutions responds to market forces. The analyses recognize five key challenges to assessing productivity in higher education: the potential for multiple student outcomes in terms of skills, earnings, invention, and employment; the fact that colleges and universities are "multiproduct" firms that conduct varied activities across many domains; the fact that students select which school to attend based in part on their aptitude; the difficulty of attributing outcomes to individual institutions when students attend more than one; and the possibility that some of the benefits of higher education may arise from the system as a whole rather than from a single institution. The findings and the approaches illustrated can facilitate decision-making processes in higher education.Hoxby, Caroline M. / Stange, Kevin -- Staiger, Douglas -- Hoxby, Caroline M. -- Minaya, Veronica / Scott-Clayton, Judith -- Riehl, Evan / Saavedra, Juan E. / Urquiola, Miguel -- Altonji, Joseph G. / Zimmerman, Seth D. -- Courant, Paul N. / Turner, Sarah -- Vlieger, Pieter De / Jacob, Brian / Stange, Kevin -- Deming, David J. / Lovenheim, Michael / Patterson, Richard -- Carrell, Scott E. / Kurlaender, Michal -- Frontmatter -- Contents -- Acknowledgments -- Introduction / 1.

How European physics reached across the Wall

Anchieta fasciatella Ardila-Camacho & Calle-Tobón & Wolff & Stange 2018, new combination
No full textAnchieta fasciatella (Westwood, 1867), new combination Fig. 3a Mantispa (Trichoscelia) fasciatella Westwood, 1867: 503. Holotype (or syntypes), female, Venezuela (OUM). Specimens examined. New records: Panama: Canal Zone, Albrook Forest Site, 30.40 m, 25‒26.VII.1968, black light trap, R. S.

Colombia (Bolívar, Magdalena, Santander; Ardila-Camacho & García 2015), Panama (Canal Zone, Panamá Oeste, Panamá, Darién). Comments. The genus Anchieta is until now composed of seven species distributed from Panama south to Brazil. Most of the species are known from the Brazilian Amazonia, although the genus presents few records (Penny 1982). The group is separated from other Symphrasinae members by the presence of a straight rarp2 (second anterior radial cell) of forewing. Another remarkable difference, is the mimetic pattern with several families of Hymenoptera, which seems to be a generalized feature of the group. For example, A. fumosella was referred to be a mimetic of Vespidae (Buys 2008), while A. fasciatella resembles wasps of the family Braconidae (Braconinae), which have repugnant abdominal glands (Ardila-Camacho & García 2015). The remainder species present a general color pattern and the hindtibia greatly swollen and flattened, resembling stingless bees of the tribe Meliponini (Penny 1982). Some species in this genus have lateral keel like projections on the abdominal tergites of both sexes. The pterostigma on the forewing is shorter than in Plega or Trichoscelia, and the trochanter of the forelegs has a dentiform process on the inner surface. Anchieta fasciatella was originally described from Venezuela. However, this record is now considered erroneous because the type locality, Santa Marta, is not located in Venezuela, but in Colombia. In fact, Ardila- Camacho & García (2015) reported this species as Plega fasciatella from several localities in Colombia. Moreover, in the revision by Penny (1982), this species was mentioned as occurring in Panama, however, no specific data were provided by the author. Here we present the first specific records of this species from Panama.Published as part of Ardila-Camacho, Adrian, Calle-Tobón, Arley, Wolff, Marta & Stange, Lionel A., 2018, New species and new distributional records of Neotropical Mantispidae (Insecta: Neuroptera), pp. 295-324 in Zootaxa 4413 (2) on pages 297-298, DOI: 10.11646/zootaxa.4413.2.4, http://zenodo.org/record/122696
Ketogene Ernährung [Ketogenic diet]
No full textVon den drei Makronährstoffen in unserer Ernährung sind nur Kohlenhydrate nicht essenziell. Bei deutlicher Einschränkung der Kohlenhydratzufuhr wird ein physiologischer Prozess in Gang gesetzt, der zur Bildung von Ketonkörpern aus Fetten führt, die sogenannte Ketogenese. Im Gegensatz zum Fasten geschieht dies im Rahmen einer ketogenen Diät (KD) nicht ausschließlich aus körpereigenen Fettreserven, sondern auch aus zugeführten Nahrungsfetten (Beispielmahlzeit in . Abb. 12.1). Bereits vor etwa 100 Jahren wurde erkannt, dass eine KD wie das Fasten eine Ketose induziert, aber langfristiger, z. B. zur Therapie von therapierefraktärer Epilepsie und Diabetes Typ 2, eingesetzt werden kann. In diesem Beitrag lesen Sie über die Entstehung der KD und was sie ausmacht, die vermuteten Wirkweisen, Formen und aktuellen Anwendungsgebiete der KD, Aspekte der praktischen Umsetzung in der Ernährungstherapie, Messung und Beurteilung von KetonWerten, sowie Compliance, Risiken, Kontraindikationen und kritische Aspekte
Wassergefilterte Infrarot-Hyperthermie – Lassen sich muskuloskelettale Schmerzen wegschmelzen?
No full textSummaryWassergefilterte Infrarot-Hyperthermie wird außerhalb der Onkologie auch für weichteilrheumatische Beschwerden und Arthrosen genutzt. Erste Studien zur seriellen Anwendung der Ganzkörperhyperthermie mit Fibromyalgiepatienten sowie bei ankolysierender Spondylitis liefern vielversprechende Ergebnisse hinsichtlich Schmerzreduktion sowie der Auslösung adaptiver Prozesse.Der Beitrag gibt einen Überblick zur bisherigen Studienlage bei muskuloskelettalen Schmerzen, den Applikationsformen, der Anwendung in der Praxis, Verträglichkeit und Sicherheit sowie den Möglichkeiten der Kostenerstattung.</jats:p
