Virtuelle Maschinen: zSeries- und S/390-Partitionierung     

Joachim von Buttlar  Wilhelm G. Spruth 《Informatik - Forschung und Entwicklung》2004,39(1):41-54

Der gleichzeitige Betrieb mehrerer Gast-Betriebssysteme auf einem einzigen physischen Rechner unter einem Host-Betriebssystem ist eine leistungsfähige moderne Entwicklung. Bekannte Beispiele sind VMware für die IA32-Architektur sowie das Betriebssystem z/VM und die PR/SM-LPAR Einrichtungen der zSeries-Architektur. Die Nutzung eines Betriebssystems als Gast bedingt einen Leistungsverlust. Die als Partitionierung bezeichnete Zuordnung von Systemressourcen zu den einzelnen Gast-Betriebssysteme ist schwierig, wenn eine dynamische Anpassung an sich ändernde Lastprofile erforderlich ist. Diese Probleme lassen sich mittels Erweiterungen der Hardwarearchitektur adressieren, sowie durch Softwarestrukturen, welche diese Erweiterungen nutzen. Die Erweiterungen der Hardwarearchitektur gehen über das hinaus, was auf heutigen Rechnerarchitekturen wie IA32 oder Mips verfügbar ist. Der vorliegende Beitrag erläutert den optimalen Betrieb von Gast-Betriebssystemen und die begleitenden Partitionierungsmöglichkeiten auf der zSeries-Plattform und beschreibt die zusätzlichen Hardware- und Software-Einrichtungen, welche dies ermöglichen.  相似文献

Acquiring Clinical Knowledge from an Online Video Platform: A Randomized Controlled Experiment on the Relevance of Integrating Anatomical Information and Clinical Practice     

Johannes Grosser  Martina Bientzle  Thomas Shiozawa  Bernhard Hirt  Joachim Kimmerle 《Anatomical sciences education》2019,12(5):478-484

Basic subjects in medical education, such as anatomy, are often taught through teaching formats that do not always sufficiently demonstrate the relevance of this basic information for clinical practice. Accordingly, it is a recent trend in anatomy education to link anatomical information more explicitly to clinical practice. This article presents an online video platform (Tuebingen’s Sectio Chirurgica [TSC]) as one means of explicitly integrating preclinical anatomical knowledge and clinical application. The purpose of the study presented here was to examine the effects of videos through which medical students were educated about Anterior Cruciate Ligament reconstruction. A TSC video about this surgical procedure was compared to a video with a traditional lecture providing the identical information. Participants (n = 114) perceived the TSC video to be superior in comprehensibility of the presentation (P = 0.003) and conceivability of the surgical procedure (P = 0.027), and to be more entertaining (P < 0.001). Moreover, participants in the TSC condition acquired more clinical knowledge than in the lecture condition (P = 0.043) but did not differ in their acquisition of anatomical knowledge. Mediation analyses indicated that the effect on the acquisition of clinical knowledge was mediated by comprehensibility, conceivability, and entertainment. These findings are discussed regarding their implications for medical education in terms of contributing to the general trend of linking preclinical anatomical knowledge to clinical application. A discussion about the limitations of the study and suggestions for future research are also provided.  相似文献

Rediscovering the political dimension of the personal life story: results from an intergenerational narrative learning project with older adults in South Westphalia     

Joachim Broecher  Joyce H. Davis  Janet F. Painter 《International Journal of Lifelong Education》2017,36(4):471-485

Using qualitative interviews, focus groups, storytelling and collective journaling, the life experiences of people in a local village community, in South Westphalia, Germany, born between 1930 and 1945, were analysed collaboratively. The research intention was to give the younger generations in that region access to these experiences and insights, within the context of democratic learning and civic education. The focus of this narrative learning project was on the politically relevant issues and themes they contained, above all: the significance of free information and thought, a free cultural life, access to education for all children and youth, a self-determined life for women and girls, as well as cohesion and self-help structures in the social community. Many tales were shared from the Third Reich, making references to Wilhelmine Germany and the Republic of Weimar, including how these times had been narrated to them through their forebearers and families’ archives.  相似文献   

Soziale Ungleichheit beim Zugang in eine Berufsausbildung: Welche Bedeutung haben die Institutionen?     

Mona Granato  Joachim Gerd Ulrich 《Zeitschrift für Erziehungswissenschaft》2014,17(2):205-232

The corporatistic governance model of nonacademic vocational training, which is predominant in Germany, has produced heterogeneous and complex conditions for the access to vocational training. Which training programs are offered and the selection of applicants is largely determined by the training companies themselves. Adolescents interested in vocational training are thus confronted with diverse admission requirements. Which resources they can and have to use in order to receive a training position is significantly determined by the respective admission requirements. The present paper elucidates key institutional conditions of the access to vocational training which can serve as explanations for the (re-)production of social inequalities in the transition process from school to vocational training. In particular, the inequalities with respect the admission to vocation training along the lines of educational degrees, gender, as well as regional, social, and ethnic backgrounds are investigated.  相似文献

THE DEPICTION OF SEX ROLES IN AMERICAN AND GERMAN MAGAZINE ADVERTISEMENTS*     

Brosius  Hans-Bernd; Mundorf  Norbert; Staab  Joachim F. 《Int. Journal of Public Opinion Research》1991,3(4):366-383

This study provides a quantitative content analysis of the depictionsof sex roles in the American news magazine Time and the WestGerman news magazine Stern from 1969 to 1988. The underlyingassumption of the study is that advertisements reflect changesin social reality. While most studies focus on explicit aspectsof gender role depictions such as jobs, activities, interactionsand situations, this content analysis also covers implicit aspectsof role depictions such as posture, gestures, and facial expression.Some authors have claimed that these are powerful means of transmittingtraditional sex role stereotypes of women as being submissiveand of men as being dominant. Results indicate that while therehave been considerable changes in the explicit presentationof male and female roles, the implicit presentation remainedquite consistent over the 20-year period. According to thesefindings, sex roles may have changed primarily on the surface,while nonverbal sex role stereotypes still linger on. Differencesbetween the developments in Germany and the US are outlined.  相似文献
