INTRODUCTION Mobile IPv6 (MIPv6) (Johnson et al., 2004) was proposed to maintain network connectivity in the next generation Internet. However, communication quality of MIPv6 degrades because of the high signaling overhead and the long signaling delay when a mobile node (MN) performs handover. Hierarchical Mobile IPv6 (HMIPv6) (Soliman et al., 2005) was proposed to improve the performance of MIPv6, where the Mobility Anchor Point (MAP) handles mobility in- side the local domain… 相似文献

Activity 2 of project E4, “Quality Assessment and Transparency for Enhanced Mobility and Trans-European Recognition”, included the working group on “Quality Assurance in Engineering on a National and European Scale”. Its report can be found in Part 2 of Volume D, final report of the E4 Thematic Network (Firenze University Press 2003).
The Report of this Working Group is formed by three parts.
Chapter 2 explores the horizon of evaluation, and briefly summarizes evaluation mandate, focus and procedures in the light of quality and quality assurance, accreditation, responsibility, with particular reference to higher education.
Chapter 3 explores the ideas from a number of European evaluation models for higher education, and shows that their contents can be read in the frame of four fundamental “aspects” or “dimensions” of quality:
-
–?Requirements, objectives
-
–?Teaching, learning, assessment
-
–?Learning resources
-
–?Monitoring, analysis, improvement
Chapter 4 underlines that a Programme should be evaluated on the basis of its ability to put into effect a policy focusing—clearly and distinctly—on the external and internal efficacy of the learning process: specify worthwhile learning goals and enable most students to achieve the established objectives. The set of “aspects” examined in Chapter 3 is expanded into a minimum set of “factors”, that the Programme should address in a stable manner before it is submitted to an external evaluation.
In developing this activity, a selection of a few representative models was examined, bringing out the essential structure that they have in common. The reference documents can be found in the References section of this article. What follows is extracted from the conclusions of Chapter 4. 相似文献

ABSTRACTTravel has become ubiquitous for most social groups as holidaying abroad has become ever cheaper and ecumene. This paper considers how travel can be understood as part of family practices around children’s educations and futures. Drawing on Kaufmann’s concept of motility, we examine how spatial mobility might become a form of cultural capital to reproduce privilege or facilitate social mobility. We generated data on family spatial mobility during the act of international air travel itself, interviewing 22 participants. We argue that spatial mobility and its link to social mobility is differently conceived of by our working, middle, and global middle class families, but that all three seek to use travel overtly as a form of cultivation for their children. This leads us to suggest that international travel may illuminate new ways that social class differentiations and lines of striation are being forged through movements across transnational spaces, offering new insights for education professionals and scholars. 相似文献

This study focuses on the effect of university education on developments relating to people's choice of residence in Iceland. In order to gain answers to the research questions, secondary data were obtained from official sources, trade unions, the data bank of the Social Science Institute, University of Iceland, and by interviewing 20 nursing and business administration graduates in Akureyri and Reykjavík. The conclusions indicate that a university education strongly affects various aspects of regional development. Graduates from the University of Iceland are a great deal likelier to settle in the area of the capital than graduates from the University of Akureyri, and vice versa . University education also has a notable influence on earnings, depending on the constituency in question, and a survey demonstrated that the origin of the persons interviewed and the residence of their parents were highly significant factors concerning the university they selected for study and their choice of residence after graduation. Furthermore, project work undertaken by the interviewees and their professional training during their course of study also had a considerable influence on their choice of employment after they had completed their studies. This is explorative research based on a restricted sample. The project provides important information, but the reader is warned against excessive generalisation based on the conclusions. 相似文献

中国的改革开放预期了人力资本对社会流动与分层的重要作用。对人力资本、政治资本等回报问题的研究,成为海外中国研究判断市场经济改革现存问题和未来走向的重要依据。1989年,美籍华裔社会学家倪志伟(Victor Nee)率先提出市场转型论(Theory of MarketTransition)进行解释,认为随着改革的推进,将会出现人力资本回报提升、政治资本回报下降的局面。文章鲜明的观点引发了持久争论。为了应对批评,倪志伟先后发表系列文章,对其观点进行持续修正。现在看来,倪志伟的结论当然有固有的缺陷,但对其的批评的确也有误解的成分。同时,包括倪志伟在内的研究者都力求提取简洁的理论模型,追求统一模式,这也为其理论纰漏提供了空间。 相似文献

Most studies of student migration focus on interstate migration of college students, largely because the aggregate data typically used are limited in geographic specificity to states. However, interstate migration is only a small part of the total student migration. Public institutions generally get most of their students from within their state; for example, 88 percent of first-time freshmen who enrolled in University System of Georgia institutions in 2002 graduated from Georgia schools. Such intrastate migration is seldom considered. This paper examines intrastate college student migration, using data for Georgia. Aside from such traditional measures of benefits and costs like tuition, financial aid, and school quality, a crucial explanatory variable in our analysis is the distance from a student's home to the different Georgia state institutions. Our empirical results indicate that student intrastate migration is strongly discouraged by greater distance, but with effects that differ across types of higher education institutions. 相似文献

The current explosion in mobile computing and telecommunications technologies holds the potential to transform "everyday" time and space, as well as changes to the rhythms of social institutions. Sociologists are only just beginning to explore what the notion of "mobility" might mean when mediated through computing and communications technologies, and so far, the sociological treatment has been largely theoretical. This article seeks instead to explore how a number of dimensions of time and space are being newly reconstructed through the use of mobile communications technologies in everyday life. The article draws on long-term ethnographic research entitled "The Socio-Technical Shaping of Mobile Multimedia Personal Communications," conducted at the University of Surrey. This research has involved ethnographic fieldwork conducted in a variety of locales and with a number of groups. This research is used here as a resource to explore how mobile communications technologies mediate time in relation to mobile spaces. First the paper offers a review and critique of some of the major sociological approaches to understanding time and space. This review entails a discussion of how social practices and institutions are maintained and/or transformed via mobile technologies. Ethnographic data is used to explore emerging mobile temporalities. Three interconnected domains in mobile time are proposed: rhythms of mobile use, rhythms of mobile use in everyday life, and rhythms of mobility and institutional change. The article argues that while these mobile temporalities are emerging, and offer new ways of acting in and perceiving time and space, the practical construction of mobile time in everyday life remains firmly connected to well-established time-based social practices, whether these be institutional (such as clock time, "work time") or subjective (such as "family time"). 相似文献

The internationalisation of higher education has influenced the dramatic rise in the mobility of students, academics and knowledge across borders. There has been growing research interest focusing on international students studying abroad. While the student experience is an area of education that is often researched, most research focuses on experiences of undergraduate students. Also in the context of international students, greater research emphasis has been placed on the academic experiences and support available for undergraduates. While such research is important, less attention has been paid to the non-academic experiences of International Post-Graduate Research Students with Families (IPGRSF). This article seeks to fill this gap by focusing on the social worlds of IPGRSF in the UK, examining students’ nuclear family contexts that are often marginalised in discourse. The article legitimises the IPGRSF subaltern world by focusing on how students negotiate its demands; how they negotiate their roles as research students with their other roles as spouses and parents, and the interrelationships among these roles; and how the university as an institution interacts with the students’ subaltern world. The findings show that language plays a significant role in shaping the process of mobility as well as influencing the students’ and their families’ integration and networking in the host country. Also, the findings suggest that students often had positive experiences at departmental level, but felt let down by the wider university support. 相似文献
