The Use of Time by Academic and Related Staff

This paper reviews surveys of the use of time by academic staff between 1962 and 1994. It reports on the findings of a time diary survey in 1994 of the use of time by academic and academic-related staff at British'old'universities during working weeks in term-time and vacation. The results of the time diary survey are analysed according to respondents'sex, staff grade, type of week, age, type of work, and time when work took place. The results are compared with results of previous surveys, and trends through time are suggested. In conclusion, the paper considers the recent mass expansion of higher education, the effects of this in increasing the workload of university staff, and measures to ameliorate this situation.     

Alternative technologies and social studies textbooks

In order to determine the potential of alternative technologies in social studies education, we must understand the goals of such education, the capabilities of the technologies, and teachers’ and students’ responses to new technologies. The author suggests that the new technologies can contribute to the goals of learning about the past, learning about democratic life and institutions, and making students knowledgeable as consumers and producers of information. One major obstacle is a lack of time and money for teachers to experiment with the technologies. Stephen T. Kerr is professor of education in the College of Education at the University of Washington. His research focuses on the application of new technologies in schools and other educational environments, and particularly on the ways in which technology affects the social structure (roles and expectations, instructional patterns, organization) of those institutions. He has done work on human-computer interaction, as well as on how new communication technologies have changed the educational system of the former USSR.     

Preparation for ethical decision-making: An analysis of research in professional education

The current societal and professional context presents a variety of ethical challenges to decision makers. The importance of educational preparation for ethical decision-making and ethical leadership has been addressed in the literature of library and information science (LIS), among other professions. However, it can be quite difficult to measure the impact of professional ethics education on students. This article is based on an evaluation of published original research related to ethics education in disciplines supported by professional education, including education, nursing, allied health, journalism, social work, public health, engineering, and LIS. The study considers data related to research design, methodologies used, populations studied, approaches to measuring impact, levels of impact, and publication in the journal literature. Results indicate more extensive research in education and nursing as compared with other fields, a lack of baseline data gathering for comparison, a reliance on a limited number of data-gathering techniques, and a tendency toward studying alumni over current students

Forschungs- und Entwicklungsprojekte Virtuelle Maschinen: zSeries- und S/390-Partitionierung

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.     

The Effects of Darkness and Lightness Cues in the Visual Depiction of Political Actors Involved in Scandals: An Experimental Study

Reports about political scandals have increased lately. Yet the general impact of news visuals and the specific role of lightness and darkness cues in images of scandalized politicians remain unclear. With the help of an experiment, the present pilot study examined the influence of candidate images and the effects of particular image backgrounds (light versus dark). While the foreground of the image depicting a politician involved in a scandal remained unchanged, the background was systematically altered. The results revealed that a light background had a positive effect on recipients’ attitudes toward the politician. In contrast, participants exposed to a dark image background demanded a more severe punishment for the politician.
