Because access to new technologies is unequally distributed, there has been considerable debate about the growing gap between the so‐called information‐rich and information‐poor. Such concerns have led to high‐profile information technology policy initiatives in many countries. In Australia, in an attempt to ‘redress the balance between the information rich and poor’ by providing ‘equal access to the World Wide Web’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]), the Australian Council of Trade Unions, Virtual Communities (a computer/software distributor) and Primus (an Internet provider) in late 1999 formed an alliance to offer relatively inexpensive computer and Internet access to union members in order to make ‘technology affordable for all Australians’ (Virtual Communities, 2002 Virtual Communities (2002) About us. Available online at: http://www.virtualcommunities. com.au (accessed 18 August 2002)  [Google Scholar]). In this paper, we examine four families, one of which had long‐term Information and Communication Technologies (ICT) access, and three of which took advantage of the Virtual Communities offer to get home computer and Internet access for the first time. We examine their engagement with ICT and suggest that previously disadvantaged family members are not particularly advantaged by their access to ICT.  相似文献

The differences, so far as Yugoslav legislation is concerned, between “equivalence” and “recognition” are mads clear, and the Yugoslav instances authorized to make decisions on questions of equivalence and recognition are stated and their procedures, briefly described. The 7 multilateral conventions and the 13 bilateral agreements on equivalence and recognition matters are listed. More is said about the various Yugoslav instances empowered to make decisions and to give Information on questions of equivalence and recognition.  相似文献

Brain drain has been a long‐lasting phenomenon. It existed in the former Yugoslavia, and was affected by various factors, from political through economic ones to the attractive offers for advanced studies and work in scientific institutions or firms in developed countries. Some ad‐hoc analyses were made concerning individual groups or periods, but there was no systematic monitoring and no complete and all‐inclusive data. It is however possible to draw a picture showing trends in the – mostly one‐way – movement towards highly developed countries.

Therefore, the current study has a mosaic character, which – we hope – shall throw some light and try to explain brain drain in the academic circles of Serbia and Montenegro (former SFRY). As the Republic of Serbia represents the largest component part (about 90 percent), most of the data is about Serbia.  相似文献

This article discusses some findings from a small‐scale investigation of children's gendered beliefs and behaviours in a Korean kindergarten which was attempting to challenge gender stereotyping through the anti‐bias intervention of a ‘cooking curriculum’. A sample of 14 children, some with ‘working’ mothers and some with ‘housewife’ mothers, was observed for two months, and informally interviewed on several occasions. The children's mothers were also interviewed. The findings are situated in the context of the changing, but still traditional, culture of Korean society, as well as in the contexts of early childhood education and theories of gender acquisition. They confirm that, although children are highly likely to reproduce the beliefs current in their home environment, they are open to reconstructing these views when actively challenged to consider alternatives, either by the school curriculum or by engaging in debate with a researcher or practitioner. The nature of the ‘alternative’ views available may however be problematic.  相似文献

This introductory essay reviews the key contributions of David Teece's landmark paper “Profiting from Innovation” published in research policy in 1986. It summarises the contributions of each of the papers in the special issue. It then offers some perspectives on the key themes emerging from these papers, and on the broader challenges facing researchers, strategists and policymakers in the field of technology innovation today.  相似文献

There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble solution. The children then participated in weekly, experimenter-provided activities that fostered their acquisition of the color labels. After 2 months, their ability to apply the newly acquired words in reporting the original event was assessed. A significant proportion of the children demonstrated verbal recall when prompted in the presence of physical reminders of the event. These findings indicate that some early, preverbal memories are translated into words at a later time.  相似文献

Research‐practice partnerships offer counselor educators an opportunity to generate scholarship that can promote client welfare and create systemic change in practice and policy. The purpose of this article is to articulate strategies for building and sustaining research‐practice partnerships, as well as suggest methods for evaluating these partnerships.  相似文献
