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   

Nomadic inquiry in the smooth spaces of the field: A preface     

Elizabeth A. St. Pierre 《International journal of qualitative studies in education》2013,26(3):365-383

Framing this essay as a preface to a return to the field in order to collect more data for her study of the older, white southern women of her hometown, this researcher uses Laurel Richardson's (1994) concept of ''writing as a method of inquiry'' in order to revisit some of the places in which she has already done field work. By employing Deleuze and Guattari's (1980 1987) image of the nomad deterritorializing space, she revisits some of those spaces- mental space, the space of the text, and the space of theory- in order to work out of the failure of her received understanding of fieldwork and to think differently about the spaces and places in which her research takes place.  相似文献   

Enhancing nursing home care for seniors: impact of a living classroom on nursing assistant’s education     

Veronique M. Boscart  Lynn McCleary  Paul Stolee  Linda Sheiban Taucar  Jessica Wilhelm  Keia Johnson 《Educational gerontology》2020,46(8):461-472

ABSTRACT

Nursing Assistants (NAs) are the largest workforce in nursing homes, but often lack adequate preparation for their role. The Living Classroom (LC) is an integrated learning approach, whereby a NA program is delivered in a nursing home (NH) in collaboration with a community college. This paper describes the implementation and evaluation of the LC. Mixed methods were used to gather data from 48 NA students, 5 faculty, and 42 NH staff over 30 weeks. Students, faculty, and nursing home staff described the LC as a positive learning experience. Students’ gerontological knowledge increased over time (p = .0012). Students reported very positive relationships with program mentors and NH residents. The LC provides a unique approach to prepare NAs to work in nursing homes. This model could expand to other educational programs with a gerontology focus.  相似文献   

SPIRAL OF DISAPPOINTMENT: DECLINE IN ACHIEVEMENT AMONG GIFTED ADOLESCENTS     

Wilhelm Wieczerkowski  Tania M. Prado 《High Ability Studies》1993,4(2):126-141

The view that the pattern of development and the scholastic performance of potentially highly gifted children are as prone to disturbances as those of less gifted youngsters is now widely accepted. The emergence of giftedness and the unfolding of talent has been shown to be a developmental process, in which a variety of cognitive, noncognitive, and ecopsychological preconditions are involved. Whether the observed developmental patterns of a young person are harmonious or disruptive depends on what has been described in the literature as a favourable (vs. unfavourable) constellation of facilitating factors. With the help of a dynamic model, case studies of failure and refusal to perform in school among young underachievers are analyzed and related to previous school experiences.  相似文献   

Prediction of self-reported knowledge with over-claiming, fluid and crystallized intelligence and typical intellectual engagement     

Gizem Hülür  Oliver Wilhelm  Stefan Schipolowski 《Learning and individual differences》2011,21(6):742-746

We investigated the usefulness of the Over-Claiming Questionnaire (OCQ) as a measure of cognitive abilities. In OCQs respondents are asked to rate their familiarity with items of academic or everyday knowledge (Paulhus, Harms, Bruce, & Lysy, 2003). Some items exist in reality (reals), and others do not (foils). We developed four OCQs, each consisting of 40 reals and 8 foils from the domains of Science, Humanities and Civics. The OCQs were administered in a longitudinal rotation design to 112 participants who attended the 9th school grade at the beginning of the study. In latent variable regression analyses 53% of variation in the reals could be explained by fluid and crystallized intelligence and over-claiming as indicated by responses to foils. Further variation in responses to reals and foils was explained by intellectual engagement. Our results show that self-reported knowledge, although positively related to measures of ability, to a large extent reflects over-claiming.  相似文献   

丛林中的守财奴

[童话大意]一个农场主有一个忠诚的仆人,这个仆人辛辛苦苦地给他干了三年的活,而他却没有付给仆人任何工钱。后来仆人打定主意,想出去看看外面的世界,不再干下去了。他找到农场主说:"我为你勤勤恳恳地做了这么久的事,相信你会根据我的劳动付给我应得的工钱。"农场主是一个极其吝惜的守财奴,只拿出三便士给他,也就是一年一便士的工钱。可怜的仆人对钱没有多少概念,  相似文献   

Impact of Contact With Grandparents on Children's and Adolescents’ Views on the Elderly     

Allison Flamion  Pierre Missotten  Manon Marquet  Stéphane Adam 《Child development》2019,90(4):1155-1169

Stereotypes, prejudice, and discrimination against the elderly (ageism) may manifest themselves in children at an early age. However, the factors influencing this phenomenon are not well known. Using both explicit and open-ended questions, this study analyzed the influence of personal and familial parameters on the views of 1,151 seven- to sixteen-year-old Belgian children and adolescents on the elderly. Four factors were found to affect these views: gender (girls had slightly more positive views than boys), age (ageism was lowest in 10- to 12-year-old, reminiscent of other forms of stereotypes and cognitive developmental theories), grandparents’ health, and most importantly, quality of contact with grandparents (very good and good contacts correlated with more favorable feelings toward the elderly, especially in children with frequent contacts).  相似文献   

Measuring efficiency of Tunisian schools in the presence of quasi-fixed inputs: A bootstrap data envelopment analysis approach     

Hédi Essid  Pierre Ouellette  Stéphane Vigeant 《Economics of Education Review》2010,29(4):589-596

The objective of this paper is to measure the efficiency of high schools in Tunisia. We use a statistical data envelopment analysis (DEA)-bootstrap approach with quasi-fixed inputs to estimate the precision of our measure. To do so, we developed a statistical model serving as the foundation of the data generation process (DGP). The DGP is constructed such that we can implement both smooth homogeneous and heterogeneous bootstrap methods. Bootstrap simulations were used to estimate and correct the bias, and to construct confidence intervals for the efficiency measures. The simulation results show that the efficiency measures are subject to sampling variations. The adjusted measure reveals that high schools with residence services would have to give up less than 12.1% of their resources on average to be efficient.  相似文献   

Erfahrungen mit dem Einsatz anwendungsspezifischer Piktogramme zur partizipativen Anforderungsanalyse     

Wilhelm Hasselbring 《Informatik - Forschung und Entwicklung》1998,13(4):217-226

Zusammenfassung. Die Erfahrungen aus einem Projekt im Bereich Krankenhausinformationssysteme werden in diesem Papier diskutiert. Insbesondere konzentrieren wir uns dabei auf den Einsatz von Techniken zur partizipativen Anforderungsanalyse und die dabei für die Anwender erreichte Nachvollziehbarkeit von den ermittelten Anforderungen zum entwickelten System. Ein zentraler Aspekt ist hierbei der durchg?ngige Einsatz von anwendungsspezifischen Piktogrammen in der Modellierung der Anforderungen und in der Implementierung der graphischen Benutzungsschnittstellen, wobei auch das frühzeitige Prototyping zur überprüfung der ermittelten Anforderungen eine wichtige Rolle spielt.
