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 article highlights important developments in the character of temporary worker flows to Canada between 1973 and 1985 through the use of unpublished data and new measures for analyzing this data. The number of employment authorizations are converted to person years to indicate the overall labor market impact of temporary worker flows and this measure is employed in an analysis of unpublished data from Employment and Immigration Canada. The analysis reveals that a significant and growing proportion of employment authorizations are exempted from governmental procedures which link the admission of temporary workers to the Canadian labor market." Reasons for these exemptions and policy implications are discussed  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

This study was conducted to establish evaluation indicators to be used as a basis in evaluating the integration of the population education program (POPED) of the Ministry of Education, Culture, and Sports within the Philippine 2ndary school curriculum. Questionnaires were used to determine existing knowledge, attitude, practice and skills (KAPS) of 3,136 high school students and 490 teachers, and data was analyzed for significant relationships between KAPS concerning POPED and demographic characteristics, exposure to population information sources, type of school attended, and exposure to POPED. KAPS and teaching method determine KAPS of the student. Data indicate that 81% of teachers had integrated POPED into the curriculum; only 19% of these had attended training on POPED. 93% utilized a lecture-discussion method in teaching POPED. Knowledge tests given to students and teachers were the same, covering demography, family size, age at marriage, responsible parenthood, use-effectiveness of methods, and population and development. Teachers performed better than students in questions on knowledge; on attitude statements teachers showed a slightly more favorable attitude towards POPED issues, most favorable to responsible parenthood, and least favorable to age at marriage. Mean preferred age at marriage (25) and mean desired number of children (3) was the same for teachers and students; teachers desired wider child spacing than students (3.3 years vs. 2.7 years). 84% of teachers used or wanted to use a family planning method, 76% of students felt they would use a method after marriage. Factors useful in predicting KAPS of teachers and students on POPED are: region of residence, age, sex, educational level, marital status, grade average, type of school, and exposure to various sources of POPED information.  相似文献

Nigeria, the largest country in Western Africa, has been attracting migrants from neighboring countries for the past decade or so. Although most of the movement of African migrants has occurred outside the regulatory framework set up to control migration, it is important to know the main elements of the latter to understand the likely limitations of the data collection systems currently in operation. Sources of data on international migration include censuses, arrival and departure statistics, work and resident permits, and sample surveys. The author concludes that, with the exception of information on residence and work permits, the relationship between Nigeria's data sources and the laws regulating migration is weak. Arrival and departure statistics, in particular, are not designed to distinguish migrants from all other international travellers. Lacking the political will to modify the system in accordance with internationally accepted recommendations, the prospects for increasing the usefulness of available data are grim.  相似文献

A typology of migration is presented that extends the one originally developed by William Petersen, which was based on ecological push, migration policy, people's aspirations, and social momentum. The proposed typology considers both the migrant's state of mind and two points in time. Examples of 36 migrant types are provided using data for Canada and selected other countries.

By 1989 Asia's population will reach 3 billion. That Asia's countries can change the course of population development has been shown by China, whose population growth rate has decreased to 1.2%. 58% of the world's population in 1985 was Asian, and 53% of it was concentrated in 11 Asian countries, of which 37.6% was accounted for by India and China. Asia's population density is 3 times the world average, and the number of persons sustained by a square kilometer of land in Asia is 2.5 times the world average. Asia's population is young (median age 20.3), which means a high dependency burden, a large number of women of childbearing age, and low quality of life, as measured by infant mortality, life expectancy, and literacy. Rapid population growth ensures a low rate of development. Asia's goals are to achieve a 1% growth rate by year 2000, zero population growth and replacement level by 2015 for East Asia and 2020 for South Asia. The World Bank estimates that Asia's population will not stabilize until the end of the 21st century, by which time it will have reached 6 billion. Asia must find a way of achieving both population control and economic development. 5 recommendations are made to the Asian Forum of Parliamentarians on Population and Development (AFPPD): 1) that the AFPPD sponsor the activities of "the Day of 3 billion"; 2) that seminars and conferences on population be held among Asian nations; 3) that high-fertility countries adopt late marriages, few births, and programs for maternal and child health; 4) that organizations for family planning be strengthened and given the resources to upgrade the status of women; and 5) that international cooperation in the area of population be intensified.  相似文献

一、森林之歌在扎伊尔的艾图瑞(Ituri)森林中,特恩布尔·科林(Coin Turnbull)和巴姆布蒂(Bambuti)人一起生活了一个阶段,他们属于矮种人.特恩布尔·科林把自己的感受写成《森林人》一书.这本书中,我最喜欢的一些事情,可能有助于阐述自己对无文字民族宗教象征艺术的性质的看法.这些事情,发生在要举行仪式之前的几个月中.每晚上,矮人燃起一堆专门的营火,他们集拢在火堆周围,且歌且宴.他们唱的歌直接与森林有关,把森林看作是他们的供养者,一种实体或特别是在这种场合存在于他们知觉中的神.森林以动听的歌回报他们,歌声从营地四周森林的各个位置发出,响彻夜空,终夜不绝入耳.森林之歌产生于熟练的喇叭筒游戏.这种仪式和吼声器,统称为"莫里莫"(Molimo).  相似文献
