Parents studying medicine : the dichotomy of studying with a family
No full textIntroduction: In this article the personal study and life situation of parents who are also medical students at the Medical School of the Goethe University Frankfurt am Main is discussed. There is a special focus on the topics "studying with children" and "family-friendly university", which have been present in discussions about university development and in the daily life of academics, especially during the last decade. The workgroup "Individual Student Services" at the medical faculty at the Goethe University tries to meet the necessities of the individual study courses and to support the study success with a new counselling and student service concept.
Methods: The experience of parents studying medicine was recorded in semi-structured interviews (Date: April 2010), which were held as part of the sponsored pilot project on part-time medical studies ("Pilot Project Part-time Medical Studies"). Additionally, study results from the Medical School of the Goethe University Frankfurt am Main were integrated as well as a literature analysis.
Results: It was found that the teaching demands and support services, which have been suggested and needed for years now, have been partially implemented and are without sufficient support at the faculty level to date. Thus the current situation of medical students with children is still difficult and seems a big challenge for everyone involved.
Solution: As part of the "Individual Student Services" a new pilot project on part-time medical studies was established in November 2009. Only the use of new, unconventional and innovative ideas allows universities to adequately support the changing and heterogeneous student population and support them to successfully completing their medical studies
Interpretations and implications of the top quark rapidity asymmetries A(FB)(t) and A(FB)(l)
No full textForward-backward asymmetries A(FB)(t) and A(FB)(l) are observed in the top-quark t rapidity distribution and in the rapidity distribution of charged leptons l from top-quark decay at the Tevatron proton-antiproton collider, and a charge asymmetry A(C) is seen in proton-proton collisions at the Large Hadron Collider (LHC). In this paper, we update our previous studies of the Tevatron asymmetries using the most recent data. We provide expectations for AC at the LHC based first on simple extrapolations from the Tevatron, and second based on new physics models that can explain the Tevatron asymmetries. We examine the relationship of the two asymmetries A(FB)(t) and A(FB)(l). We show their connection through the (V - A) spin correlation between the charged lepton and the top quark with different polarization states. We show that the ratio of the two asymmetries provides independent insight into the physics interpretation of the top-quark asymmetry. We emphasize the value of the measurement of both asymmetries, and we conclude that a model which produces more right-handed than left-handed top quarks is suggested by the present Tevatron data.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000322145600004&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)7ARTICLE1null8
Top Quark Production Asymmetries A(FB)(t) and A(FB)(l)
No full textA large forward-backward asymmetry is seen in both the top quark rapidity distribution A(FB)(t) and in the rapidity distribution of charged leptons A(FB)(l) from top quarks produced at the Tevatron. We study the kinematic and dynamic aspects of the relationship of the two observables arising from the spin correlation between the charged lepton and the top quark with different polarization states. We emphasize the value of both measurements, and we conclude that a new physics model which produces more right-handed than left-handed top quarks is favored by the present data.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000300247100002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Physics, MultidisciplinarySCI(E)EI20ARTICLE6null10
Depolarization and decreased surface expression of K+ channels contribute to NSAID-inhibition of intestinal restitution
No full textNon-steroidal anti-inflammatory drugs (NSAIDs) contribute to gastrointestinal ulcer formation by inhibiting epithelial cell migration and mucosal restitution; however, the drug-affected signaling pathways are poorly defined. We investigated whether NSAID inhibition of intestinal epithelial migration is associated with depletion of intracellular polyamines, depolarization of membrane potential (Em) and altered surface expression of K+ channels. Epithelial cell migration in response to the wounding of confluent IEC-6 and IEC-Cdx2 monolayers was reduced by indomethacin (100μM), phenylbutazone (100μM) and NS-398 (100μM) but not by SC-560 (1μM). NSAID-inhibition of intestinal cell migration was not associated with depletion of intracellular polyamines. Treatment of IEC-6 and IEC-Cdx2 cells with indomethacin, phenylbutazone and NS-398 induced significant depolarization of Em, whereas treatment with SC-560 had no effect on Em. The Em of IEC-Cdx2 cells was: −38.5±1.8mV under control conditions; −35.9±1.6mV after treatment with SC-560; −18.8±1.2mV after treatment with indomethacin; and −23.7±1.4mV after treatment with NS-398. Whereas SC-560 had no significant effects on the total cellular expression of Kv1.4 channel protein, indomethacin and NS-398 decreased not only the total cellular expression of Kv1.4, but also the cell surface expression of both Kv1.4 and Kv1.6 channel subunits in IEC-Cdx2. Both Kv1.4 and Kv1.6 channel proteins were immunoprecipitated by Kv1.4 antibody from IEC-Cdx2 lysates, indicating that these subunits co-assemble to form heteromeric Kv channels. These results suggest that NSAID inhibition of epithelial cell migration is independent of polyamine-depletion, and is associated with depolarization of Em and decreased surface expression of heteromeric Kv1 channels.ID: S0006295207001931; M3: Article; Accession Number: S0006295207001931; Author: L.C.

The consumer as a driving force behind the greening of industry: the question of policy instrument choice
No full textRetelling racialized violence, remaking white innocence: the politics of interlocking oppressions in transgender day of remembrance
No full textTransgender Day of Remembrance has become a significant political event among those resisting violence against gender-variant persons. Commemorated in more than 250 locations worldwide, this day honors individuals who were killed due to anti-transgender hatred or prejudice. However, by focusing on transphobia as the definitive cause of violence, this ritual potentially obscures the ways in which hierarchies of race, class, and sexuality constitute such acts. Taking the Transgender Day of Remembrance/Remembering Our Dead project as a case study for considering the politics of memorialization, as well as tracing the narrative history of the Fred F. C. Martinez murder case in Colorado, the author argues that deracialized accounts of violence produce seemingly innocent White witnesses who can consume these spectacles of domination without confronting their own complicity in such acts. The author suggests that remembrance practices require critical rethinking if we are to confront violence in more effective ways.

'In God we trust?': Diskursive Macht religiöser Akteure in der Entwicklungspolitik
No full text"Religiöse Akteure sind in den letzten Jahren zunehmend in den Blick politikwissenschaftlicher Analysen geraten. Als global agierende Akteure nehmen sie Einfluss auf entwicklungspolitische Fragen, die zugleich die normativen Grundlagen einer internationalen Gesellschaft als Wertegemeinschaft berühren. In der Global Governance Literatur kommen religiöse Akteure überraschenderweise jedoch kaum vor. In den IB wurden diese Entwicklungen von konstruktivistischen Ansätzen aufgenommen, die den Blick auf die Rolle von Ideen, Normen und Identitäten richten. In diesem Papier nehmen wir die diskursive Macht transnationaler religiöser Akteure in der internationalen Entwicklungszusammenarbeit in den Blick. Diskursive Macht resultiert dabei aus ideellen systemischen Faktoren und spielt in dem Ausmaß, in dem politische Entscheidungen vom Wettbewerb um Definitionshoheit im öffentlichen Diskurs abhängen, eine bedeutende Rolle. Die diskursive Macht privater Akteure wird durch ihre Akquisition von politischer Legitimität konstituiert. In der internationalen Entwicklungszusammenarbeit können religiöse Akteure diskursive Macht ausüben, indem sie Themen auf die politische Agenda bringen oder öffentliche Diskurse strategisch rahmen. Um die Wirkungsweise diskursiver Macht zu untersuchen, plädieren wir für einen interpretativen Ansatz. Konkret fragen wir nach den Bedingungen erfolgreicher diskursiver Machtausübung durch religiöse Akteure. Hierzu kontrastieren wir die erfolgreiche Einflussnahme religiöser Akteure auf politische Entscheidungsträger im Rahmen der internationalen Entschuldungskampagne mit dem Beispiel der 3. Welternährungskonferenz, die 2009 in Rom stattgefunden hat. Abschließend skizzieren wir ein Forschungsdesign, im dem wir einen genealogischer Ansatz zur Analyse der diskursiven Praktiken religiöser Akteure vor dem Hintergrund institutioneller Settings in der internationalen Entwicklungspolitik vorschlagen."
