A very large number of skilled Africans are found to be operating in the developed industrialized countries of the West at a time when their national economies are crying out for their services. Ways must be found to return as many of these skilled Africans as possible to the African economy. This out-migration or brain drain has a number of causes, including: 1) real incomes in Africa have been on the decline in the past several years while prices were constantly rising. Professional and salaried workers seek employment in other countries that pay much higher salaries. 2) Promotion on criteria other than merit is common in Africa and diligence and high productivity are not often rewarded. 3) Political interference frustrates public services professionals; they are rendered unable to use their professional judgement in making decisions that affect the economic and social fabric. 4) The inadequacy of higher education facilities and opportunities in African countries encourages the brightest and best qualified Africans to go to Western Europe and North America for school; they tend not to return after graduation. 5) Political upheavals and general instability contribute to feelings of individual insecurity, sending Africans to seek sanctuary in more politically stable and less repressive environments. Actions needed to control this out-migration include: 1) incentive systems should be reviewed with a view to providing realistic levels of renumeration and working conditions should be made to promote job satisfaction and self-actualization. 2) Capacities and capabilities should be strengthened so as to ensure that production of goods and services becomes indigenized and that the development and operation of institutions emanates from within the continent. 3) Educational services should be expanded and improved to obviate the need for large numbers of Africans to seek educational opportunities abroad.  相似文献

一、哪些做法不对?社会学确实在许多大学生的心目中威信不高,他们时常认为:社会学令人厌烦地对一些明显的、过分抽象的和对生活用处不大的事理作过分冗长的讨论,是堪与经济学并列的最"乏味"的科学.我们的一些同行认为,产生这种看法的原因是社会学太专业化和科学化了.但我们认为原因远不止此.专业化的知识对于任何寻求更多地了解世界的科学来说,似乎是必不可少的和正当的目标.问题不在于教师对学生教授了什么,而在于哪些还没有传授给  相似文献

A fact-gathering, experimental game proved to be an effective instrument in the needs assessment phase of an adolescent sexuality educational program aimed at low-income females. The game ("Family Few"), which covered the topics of menstruation and reproduction, was played by 35 Black, Hispanic, and white females aged 13-16 years recruited from medical and psychiatric clinics in Miami, Florida. The goals of the game were to elicit terminology used by participants, identify and correct misconceptions and misinformation, and determine if learning could occur. Although 57% of participants reported prior exposure to formal sex education, misinformation about the need for activity curtailment during menstruation and the importance of early pregnancy detection was widespread. Group members believed they needed to restrict activities involving physical exercise, sexual relations, water, and cold during menses and were not likely to seek medical or family consultation regarding a missed period until the end of the 1st trimester of pregnancy. Also evident was a need for accurate information on the side effects, risk factors, benefits, and effectiveness of contraceptive methods. The group responses enabled the sex educators to prepare a culturally responsive, developmentally oriented curriculum for further work with disadvantaged female adolescents. The group process was ranked highly on the Likert Scale by these teenagers as an enjoyable, useful means of information dissemination and problem solving.  相似文献

技术,现在已渗透于一切领域,与每个人都有关系.新的"高技术"产业吸引了宣传界的广泛注意.高技术产业极为重要,在该领域中落后的国家将成为一个"落后国家".但同样重要的是,大批的更为平凡而重要的其他发明创造也在诞生.几乎没有一件产品、一次加工、一种材料、一台设备没有得到重新设计和重新制造.技术不是第一次,不是第二次,也不是第三次浪潮,而是永久的浪潮.  相似文献

广为流传的政治小说和对它的理论研究之间存在着一种颇不协调的现象.近年来有关体裁方面的论著,大多对结构-类型体系、体裁-功能体系、体裁功能转换及分类这一类问题表现出浓厚的兴趣,而对政治小说则语焉不详.叶尔绍夫对苏联小说的分类最为全面,他把政治小说看作政论小说的一种.在人物描写、文体常项、文献利用诸手法上,两者确有相同的地方,但是,尽管"政论小说"的概念远比"政治小说"的概念宽,  相似文献

This preamble documents the 91 Articles of the International Convention on the Protection of the Rights of All Migrants and Their Families. This defines and covers the rights of all migrant workers and their families which can be ratified by as many countries as possible. The status and fundamental rights of migrant workers and their families have not been sufficiently recognized everywhere and therefore require appropriate international protection. The 8 parts are: 1) scope and definitions, 2) fundamental human rights of all migrant workers and members of their families, 3) additional rights of migrant workers and members of their families in a regular situation, 4) provisions applicable to particular categories of migrant workers and members of their families, 5) promotion of sound, equitable and humane conditions in connection with lawful international migration of workers and their families, 6) application of the Convention, 7) general provisions, and 8) final provisions.  相似文献

A high population growth rate in the Middle East is prompting investigators to look for cultural conditions and attitudes that can be encouraged to facilitate lower fertility rates. Population researchers find an inverse relationship between the educational level of females and their fertility, especially in Third World countries. This suggests that education can become an internal cultural mechanism for population control. The author explores this notion using data collected from interviews with 750 teenage girls and their mothers in Cairo, Egypt.  相似文献
