The nation‐building process of Timor‐Leste, the newest nation in Asia, faces significant demographic challenges due to its high population growth, which is the fastest in Asia. The major contributor for this unprecedented growth is the extremely high total fertility rate of Timor‐Leste, among the highest in the world. It is of great concern that if the current fertility rate and its implied population growth continue the population of Timor‐Leste will double in 17 years. The analysis in this paper clearly shows that the current extremely high dependency ratio will decline only marginally in the next 10 years and this will put tremendous pressure on the government to constantly keep up with the increasing number of children entering school every year. However, as the intrinsic value of human resource development feeds back into the overall society and economy, an adequate public investment in knowledge‐producing services at the earliest stages of life and throughout that life has the potential to change the demographic concern of Timor‐Leste into a future demographic dividend.  相似文献

以“科教兴国”战略的实施为标志,中国的高等教育已从社会的边缘走向社会的中心。社会对高等教育的旺盛需求,将会持续相当长的时间。随着高等教育的地位的提升,高校教师群体的不同层次均产生了明显的危机感,这种危机感的产生,是高等教育深化改革的必然。  相似文献

顾客需求方式的变化及信息技术的发展促使西方企业界进行了再造运动,即企业的流程再造,从而推动了西方企业的发展。作为世界一流大学的MIT以此为契机,掀起了一场“MIT再造”运动,取得了卓的成效。同样,面对经济改革及入世的挑战,我国的高等教育领域也应引入这种再造思想,使我国的高等教育步入与世界一体化的发展道路。  相似文献

OBJECTIVE: To compare the career paths of veterinarians who had grown up on farms with animals with those of veterinarians from other backgrounds, during the first 15 years after they graduated. PROCEDURE: Questionnaires were completed by veterinary students in their first and fifth year, and after 1, 5, 10 and 15 years after they graduated. The most recent questionnaires were returned by 134 of 137 graduates, 20% of whom had grown up, or lived for at least two years, on farms where animals were a primary source of income. This paper includes findings from that questionnaire but also contains comparisons with previous ones. RESULTS: Fifteen years after they graduated, veterinarians who had grown up on farms with animals were more likely than those of other backgrounds to be living in centres with < 10,000 people (58% farm, 20% other), irrespective of the type of work they were doing. Although they were more likely to be doing no veterinary work (42% farm, 21% other), they were also more likely to be working in mixed practice (15% farm, 9% other) and with cattle and sheep generally (11% full time equivalent farm, 5% full time equivalent other). However, > 80% of those who had started their careers in mixed practice were no longer in mixed practice after 15 years. Veterinarians of farm origin who were in private practice were more likely to be sole or part owners (93% farm, 46% other) and less likely to be employees (7% farm, 54% other). CONCLUSIONS: In this study, veterinarians who had grown up on farms with animals seemed slightly more likely than those from other backgrounds to continue working in mixed practice and to work with cattle or sheep, although the numbers were small and the differences not significant. Whatever their background, the majority who started their careers in mixed practice left over the next few years, and by 15 years only 15% remained.  相似文献

With classical sheet plastination techniques such as E12, the level and thickness of the freeze‐cut sections decide on what is visible in the final sheet plastinated sections. However, there are other plastination techniques available where we can look for specific anatomical structures through the thickness of the tissue. These techniques include sectioning and grinding of plastinated tissue blocks or thick slices. The ultra‐thin E12 technique, unlike the classic E12 technique, starts with the plastination of a large tissue block. High temperatures (30–60°C) facilitate the vacuum‐forced impregnation by decreasing the viscosity of the E12 and increasing the vapour pressure of the intermediary solvent. By sectioning the cured tissue block with a diamond band saw plastinated sections with a thickness of <300 μm can be obtained. The thickness of plastinated sections can be further reduced by grinding. Resulting sections of <100 µm are suitable for histological staining and microscopic studies. Anatomical structures of interest in thick plastinate slices can be followed by variable manual grinding in a method referred to as Tissue Tracing Technique (TTT). In addition, the tissue thickness can be adapted to the transparency or darkness of tissue types in different regions of the same plastinated section. The aim of this study was to evaluate the advantages of techniques based on sectioning and grinding of plastinated tissue (E12 ultra‐thin and TTT) compared to conventional sheet‐forming techniques (E12).  相似文献
