This paper introduces a simple framework through which the evolution of industries can be `mapped'. This framework is used to discuss the role of small firms in the development of Europe's high technology sectors during the 1980s. The framework assesses the development of high technology sectors in two dimensions (1) through the change over time in the number of units (establishments or enterprises) in these sectors and (2) through the changing employment of these sectors. Changes within both manufacturing and service sectors are discussed and differences are found between the sectors examined. Especially among the manufacturing sectors, differences are also found between countries. In some countries the high technology manufacturing sectors are growing both in terms of the number of units active in these activities and their employment, while in other countries, the number of units is increasing but employment is contracting. Within this context, it may well be that the growth in the number of high technology small firms has at least as much to do with `negative' factors, such as the `down-sizing' of large firms, as it has to do with `positive' factors, such as the creation of innovative new enterprises. 相似文献
It was just seven years ago when a commercial television station broadcast on the Greek airwaves for the first time. Today, 1997, the number of these stations has risen to 160. The formation of hundreds of commercial TV and radio stations resulted in Greece being one of the most dense media environments on the planet. Commercial television in Greece was born on 20 November 1989, when Mega Channel began broadcasting in the greater Athens area. By 1996 commercial television channels in Greece had captured approximately 90 per cent of the total viewing audience and 95 per cent of TV advertising revenue. This paper investigates the historical, legal, economic, political, and international phenomena which led to the birth of commercial television in Greece, the changes that television itself went through, the effects of these changes on Greek society, and the future prospects for Greek TV. 相似文献
In both the U.S. and the U.K. women academics are concentrated in certain subject fields. There is considerable similarity between the two countries in this respect: women are found in relatively large numbers in the humanities and are virtually absent from the applied sciences, but in both countries they are a small minority in all five major subject areas. In the U.S.A. the degree of polarisation between the men and women is greater than in the U.K. This is also true with respect to the teaching and research activities of men and women: in both countries women tend to publish fewer articles than men, but in the U.S. the difference is greater. The degree to which this is true varies according to subject fields; it is most marked in the humanities and least marked in the social sciences and applied sciences. There is one unexpected difference between the two countries: whereas in America women teach more than men, in Britain they teach less except in the social sciences. The causes of the different behaviour and interests of men and women academics are likely to be a function both of cultural definitions of male and female roles in the wider society, and institutional factors associated with educational systems both prior to the university stage and at that stage.
The aim of the study was to investigate the effects of support on knowledge acquisition of gifted learners and their flow and mood during inquiry learning. Sixty-four gifted primary school children were randomly assigned to one of three conditions differing in support given in an inquiry task. Results showed that learners who were allowed to experiment themselves learned more, experienced more flow, and felt more positive toward the task than those who were not given this opportunity, but only when they were guided through the inquiry cycle by prompts to generate hypotheses, perform experiments, and draw conclusions. The overall conclusion is that gifted children benefit more from open, complex tasks when their learning process is externally regulated. 相似文献
International concern about youth suicide has led to a growing consensus that schools are a potentially important location for suicide prevention efforts. The present study investigated the experiences and perceptions of teachers regarding a role in youth suicide prevention through semi-structured interviews which were analysed using Interpretative Phenomenological Analysis. Three themes are reported which contribute to an understanding of the construction of teacher efficacy in relation to a role in suicide prevention: baseline mastery, threats to efficacy and tension between personal and professional identities. The results indicate a mix of positive and negative experiences relating to personal, process and systemic factors. Positive elements were associated with the pastoral role. Negative experiences related to referral pathways and broader systems of care. Implications for the development of school-based suicide prevention programmes and for conceptualising processes of change in school systems are discussed. 相似文献
The gradual commodification of higher education in the context of an increased focus on graduate employability attributes together with evolving labour markets is creating challenges for universities and students alike. For universities, there has been significant investment in careers services and, through institution-wide initiatives, employability or graduate attribute development established to support graduate transitions into work. Meanwhile, for students, experience of part-time work together with pessimistic post-recession employment discourses are challenging the notion that a good degree guarantees their future career prospects. Simultaneously, decreasing financial support from the state has resulted in worrying levels of debt for new graduates. This pilot study was designed to gain a fresh perspective of how students imagine themselves following graduation. The study used rich pictures (RP) as a methodology to explore student views of life beyond university in the UK and Canada. Content analysis of the RPs provided insights into their thoughts and anxieties about potential challenges for the future. Students presented both positive and negative visions of their future, with success in achieving a respectable performance in their final degree as the key differentiator. The insights gained are discussed in the context of related research into students’ concerns and university initiatives to support students throughout higher education and then into graduate employment. The findings revealed student motivations, hopes and fears which can inform the development of impactful university interventions. 相似文献
Social validation is increasingly seen as a core component of social skills assessment. This article reviews the components of social validation (i.e., the social importance of intervention outcomes, the social significance of the goals, the appropriateness of the procedures, and determining optimal levels for target behaviours) and how they apply to social skills assessment for people with disabilities. Suggestions for future research and development of appropriate social validation measures for assessing social skills are offered. 相似文献
