Written in the twilight of the Mbeki Presidency, this paper considers the role that skills development has in the sustainability of the South African political–economic project. It explores some of the disarticulations of public policy and argues that these both undermine public sector delivery and open up opportunities for private provision to be, under certain circumstances, more responsive to the challenges of national development. We argue that there is a possibility that the state could work more smartly with both sets of providers. Crucially, however, this would necessitate working more smartly within itself. This was a major plank of the Mbeki strategy but it has failed conspicuously with regard to the Education–Labour relationship. Whether a new President can achieve a radical reworking of this relationship may be an important indicator of the viability of any new development project. 相似文献

Abstract Hearts from 126 male Sprague-Dawley rats (two age groups) were studied to determine effects of age, chronic hypoxia, and exercise on ventricular weight. Exercised rats had significantly heavier absolute total ventricular weights (right plus left) compared with chronically hypoxic or control rats. Whether expressed as absolute or percent total ventricular weight, chronically hypoxic rats had significantly larger right ventricles but significantly smaller left ventricles than exercised or control rats. Expressed as absolute weight, older rats (11 months) had significantly larger right or left ventricles than young rats (3 months). Expressed as percent total ventricular weight, young rats had left ventricles 4% smaller, but right ventricles 4% larger than older rats (p <.05). Type of work overload (volume or pressure) and functional location of workload (pulmonary or systemic) were suggested physiological mechanisms for stress- and age-related changes in myocardial mass. 相似文献

Technological progress in an industry is enabled by the collective R&D efforts of suppliers, users and research organizations. In this study, we explore how the pattern of R&D collaboration within the industry community evolves over the technology life cycle. We propose that as the technology evolves from an initial emergence stage to subsequent stages of growth and maturity, there is a corresponding change in the opportunities and challenges confronting industry participants. This results in a shift not only in the relative propensities for internal and collaborative R&D, but also in the distribution of the different types of collaborative interactions involving research organizations, suppliers and users. The context for the study is the global semiconductor manufacturing industry from 1990 to 2010. During this period, the industry experienced exponential technological progress that was fueled by the deep ultraviolet (DUV) manufacturing technology. We draw upon a comprehensive archival dataset of more than 12,000 articles presented in industry technical conferences to analyze the pattern of collaborative R&D during the emergence, growth and maturity stages of the DUV technology. The observed trends in the semiconductor manufacturing industry point to intriguing shifts in the efforts and interactions among suppliers, users and research organizations as they collectively push the technology envelope forward. 相似文献

ABSTRACTDisruptive student behaviour is a major concern for teachers, causing classroom conflict and emotional fatigue. Whilst student-teacher closeness is known to reduce student aggression and improve behaviour, it is not yet known why some teachers experience close relationships with disruptive students and others do not. This qualitative study therefore examined relational closeness between elementary teachers and disruptive students in Sydney, Australia. Using a teacher speech sample task, we identified eight disruptive students with ‘complicated’ student-teacher relationships: high in both closeness and conflict. Eleven classroom teachers and seven support teachers each spoke about their relationships with the eight students. Speech samples were analysed using an inductive content analysis to determine characteristics that may facilitate relational closeness in spite of student-teacher conflict. Findings revealed two characteristics of teachers’ speech that guided relational closeness: attributions for disruptive behaviour and emotional competence. Not all teachers, however, described a close relationship. These findings provide new directions for interventions that aim to improve student-teacher relationship quality. 相似文献

Despite the emergence of massive open online courses (MOOCs) and the field of MOOC research, we have a limited understanding of the specific needs of different learner groups and how MOOCs can successfully address those needs. Video lectures and demonstrations are a central learning component of MOOCs. This paper contributes to the research community by examining the use of MOOC videos for two groups of learners. In particular, we explore whether there is an observable difference between specialists' and non-specialists' video-watching activity. We analyse data collected from three MOOCs on the edX platform. Our findings indicate that while age and educational background impacts the level of video activity, there is no significant difference between specialists and non-specialists. We conclude that the MOOC format may be suited to non-specialist groups, allowing them to self-direct their learning and utilise videos as educational resources. 相似文献
