Zusammenfassung Die Nutzung von Java zur Entwicklung von Anwendungen für Hochleistungstransaktionssysteme stellt besondere Anforderungen an
die Isolation und das Leistungsverhalten in der transaktionalen Ausführung.
In dem vorliegenden Beitrag wird eine neuartige Technologie beschrieben, die verbesserte Isolationseigenschaften und eine
erhebliche Leistungssteigerung erm?glicht. Die Persistent Reusable Java Virtual Machine erweitert eine normale Java Virtual Machine um gemeinsam genutzte Klassen und um eine Reset-Funktionalit?t, die eine serielle
Wiederverwendbarkeit erm?glicht.
In einer Benchmark-Untersuchung unter z/OS wurde hiermit ein Performance-Gewinn um einen Faktor 325 im Vergleich mit einer
normalen JVM erreicht. Für das Erstellen von Transaktionsanwendungen unter dem Betriebssystem z/OS sind Enterprise Java Beans
damit eine ernstzunehmende Alternative zu bisherigen Programmiermodellen.
The use of Java for the development of new applications in high-end transaction systems generates special isolation and performance requirements. A new technology offering improved isolation and a significant performance improvement is discussed in this article. The Persistent Reusable Java Virtual Machine extends a regular Java Virtual Machine by adding the facility to share classes and by providing a reset functionality, which permits serial reuse of the JVM. A z/OS benchmark demonstrated a performance improvement by a factor of 325, compared to a regular JVM. Thus the use of Enterprise Java Beans has to be considered as a serious alternative when developing new transactional applications under the z/OS operating system.

A quantitative method of mapping the web usage of an innovative educational portal is applied to analyze the behaviour of
users of the COSMOS Science Education Portal. The COSMOS Portal contains user-generated resources (that are uploaded by its
users). It has been designed to support a science teacher’s search, retrieval and access to both, scientific and educational
resources. It also aims to introduce in and familiarize teachers with an innovative methodology for designing, expressing
and representing educational practices in a commonly understandable way through the use of user-friendly authoring tools that
are available through the portal. As a new science education portal that includes user-generated content, the COSMOS Portal
encounters the well-known “new product/service challenge”: to convince the users to use its tools, which facilitate quite
fast lesson planning and lesson preparation activities. To respond to this challenge, the COSMOS Portal operators implemented
a validation process by analyzing the usage data of the portal in a 10 month time-period. The data analyzed comprised: (a)
the temporal evolution of the number of contributors and the amount of content uploaded to the COSMOS Portal; (b) the number
of portal visitors (categorized as all-visitors, new-visitors, and returning-visitors) and (c) visitor loyalty parameters
(such as page-views; pages/visit; average time on site; depth of visit; length of visit). The data is augmented with data
associated with the usage context (e.g. the time of day when most of the activities in the portal take place). The quantitative
results indicate that the exponential growth of the contributors to the COSMOS Portal is followed by an exponential growth
of the uploaded content. Furthermore, the web usage statistics demonstrate significant changes in users’ behaviour during
the period under study, with returning visitors using the COSMOS Portal more frequently, mainly for lesson planning and preparation
(in the afternoon hours). The findings demonstrate that the new COSMOS users follow the “law of surfing” behaviour, a common
pattern of surfing behaviour in portals. However, users return to the COSMOS Portal: returning users comprise more than 50%
of all COSMOS visits, stay longer on site and visit more pages. Returning visitors are benchmarked against the “law of surfing”
and outperform it substantially. These quantitative results benchmark the web usage of a portal and provide its operators
with maps of value-added patterns of the portal’s offering to its users in the science education community. 相似文献

The Self-Report Checklist for Social and Learning Behaviour (SSL) is a student questionnaire comparable to the Teacher Report Checklist for Social and Learning Behaviour. The SSL assesses ten facets of social and learning behaviour using self-reports by students. The present study of 1267 students aged 9 to 19 years examines the factorial structure, psychometric properties and validity of this questionnaire. The reliabilities (Cronbach’s Alpha, retest) of all ten scales were sufficiently good and the postulated factorial structure was found in exploratory as well as in confirmatory factor analysis. Correlations of SSL-scales with scales of the Differencial Aggression Questionnaire and the Strengths and Difficulties Questionnaire as well as with grades in German and mathematics indicated mainly convergent and divergent validity. Furthermore, positive correlations were found to corresponding teacher ratings. 相似文献

Against the background of discourses concerning regional educational landscapes and the increasing interest in theoretical constructs of “space” in educational theory, this article addresses the question of how educational spaces are collectively understood in adult education organizations. This question is examined through a qualitative reconstructive study. Data sources for the study include group discussions and interviews from nine general adult education organizations chosen through theoretical sampling. The data analysis was conducted using a documentary interpretation method. The results indicate that the organizations studied reveal perspectives of educational spaces that differ along lines of territorial and experiential understanding. The concluding discussion provides hypotheses concerning possible connections between socio-economic structures and a territorial understanding of space and between the organizational or subject matter constitution of organizations and an experiential understanding of space. 相似文献
