The age structure of a population is one basic factor of population research. It is not only affected by birth, death, immigration, and marriage, but it also reflected in changes of family size. The article analyzed it from two aspects: (1) the age structure of population acts on the size and structure of the family. The younger the age structure, the larger the family size. Otherwise, it is the opposite. According to the 1982 census, 35.4% of the population was 0-14 years in rural areas, and average family size was 4.6; but in urban areas 26.0% of the population was 0-14 years and family size was 3.9. The family was characterized as a nuclear family as industrialization in economic development increased and the population aged. In the 1982 census, 64.7% were nuclear family and 6% were aging population in China. Three- generation families (or more) have decreased dramatically. The change of family size and structure is affected by change of internal family age structure. The younger population (0-14 years) is dependent and 90% live with their parents. The adult population (15-59) years are more affected by marriage, birth and social economic action. Families are established in this age period and give much more effect to fertility. The aging population (over 60) years is facing changes. They appear to be a "Defect" family because the wife or husband has passed away. They change from independent to dependent. 78.3% population over 60 years were dependent on children or social welfare, only 21.7% were independent according to the survey in Beijing Changping County. 相似文献

It was tested whether professional actors would be able to communicate emotional meaning via facial expression when this is presented to judges without context information. Forty takes were selected from movies, depicting a female or a male actor in close-up showing facial expression. These close-ups were selected by two expert judges, who knew the complete movie and had to agree on the emotion expressed or expected to be expressed by the female or male actor in the respective take. Five takes each were selected to represent the basic emotions of joy, sadness, fear, and anger. Twenty takes each were selected showing female and male actors. These 40 takes (edited in random order onto video tape) were presented to 90 judges (about half female and half male; about half younger pupils and about half older ones), whose task it was to judge the emotion(s) expressed on nine 5-point-emotion scales. Results indicated that female actors are somewhat better (though not statistically significant) in communicating emotion via facial expression without context than male actors are. Furthermore, significant interactions between portrayed emotion and gender of actors were found: While recognition rate for joy is very high and identical for both genders, female actors seem to be superior in communicating fear and sadness via facial expression, while male actors are more successful in communicating anger. A display rule approach seems to be appropriate for the interpretation of these results, indicating that gender-specific attempts to control/inhibit certain emotions do not only exist in real life, but also in movies.The research reported here was supported by a grant of the Deutsche Forschungsgemeinschaft (WA 519/2-2). I thank Uwe Balser and Tina Mertesacker for their help in selecting the stimuli, preparing the judgment tapes, recruiting subjects and conducting the study. 相似文献

The current status of fertility and its control in France is reviewed. Consideration is given to changes in contraceptive usage, nuptiality, educational status and fertility, birth timing and spacing, and female labor force participation. The author notes that fertility has not declined significantly since the mid-1970s. Fertility differentials by geographical region and occupation are also considered. 相似文献

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census." 相似文献

A comparison of the Korean minorities in China and Japan 总被引:1,自引:0,他引:1
Min PG 《The International migration review》1992,26(1):4-21
"This article compares the Korean minorities in China and Japan in their differential levels of cultural autonomy and ethnic identity....In explaining the differential levels of ethnicity between the two Korean minority groups, this paper focuses on the basic differences in minority policy between the two countries; the difference in the context of migration; the existence or absence of a territorial base; and the differential levels of influence from Korea." 相似文献

College newspapers are a powerful but underutilized medium for educating students on health issues, including those related to drug and alcohol use on campus. Editors of these publications are in a position to wield significant influence among their readers. In addition to communicating factual information about the prevalence and impact of substance use among college students, editors can use the press to advocate changes in students' attitudes and behaviors and in college or community policies that affect substance use. A pilot conference was held to help New England college newspaper editors perceive the importance of their role in educating their peers about substance use and other health-related issues, and to offer concrete suggestions as to how they can incorporate these topics into an "activist" campus press. 相似文献

Although the vast majority of deaths occur among terminally ill geriatric patients, little is known about the etiology of these patients' death acknowledgement and ultimate type of treatment. Based on interviews with 76 triads composed of physicians, terminally ill patients, and primary caregivers, this study uses the socialization perspective to identify the actors and actions that most strongly affect the patient's death acknowledgment and receipt of exclusively palliative care (i.e., socialization to the dying role). Whereas patient preferences and sociodemographic characteristics do not influence significantly the patient's odds of death acknowledgment, these odds are increased if their primary caregivers accept death, their physicians are not affiliated with a teaching hospital, and the terminal prognosis is disclosed to them and disclosed "matter-of-factly." Patients who acknowledge death, whose agents value pain alleviation over life-prolongation, and whose physicians are not affiliated with a teaching hospital, are substantially more likely to receive exclusively palliative rather than curative terminal treatment. 相似文献

A case study of temporary and circular Melanesian population mobility and labor migration focuses on the island of Paama in the Republic of Vanuatu (an archipelago of 80 islands) in Melanesia and on urbanization, which is a relatively recent phenomena. A critical analysis is provided of temporary and permanent migration and methodological inadequacies in explanations of mobility. Mobility is neither a cause nor a result of economic, social, and political change; it is the interrelationship among the general structural setting, people's personal and social environment, and their perceptions and actions. In the case of Paamese mobility, changes appeared in the source of migration and destination areas. There was a period of original land acquisition, when migrants returning from Queensland with tools were the only ones who could actually acquire land. Inequalities of land access date from this period. The population is dependent on external income sources as well as the need for plantation migration and a huge increase in bridewealth. Concurrently, "kampani" or community work, which ensures the continuous authority of local chiefs and village elders, creates problems for those seeking work for their own families. These conditions encourage out-migration. Rapid urban growth began in the 1960s with a diversified economy. Employment opportunities were available for women; single employee residence spaces declined. This meant families could permanently settle in urban areas. Retirement benefits were also available and contributed to securing permanent migration. There were growing needs for a stable, skilled labor force. Another change was the abolishment of the tripartite colonial administration. Rural disasters and price declines also triggered urban migration. Migration to the town of Port Vila by Paamese men and women between 1953 and 1982 is analyzed, based on 258 employment related mobility histories collected in 1982-83. Two processes are evident: continued periodic, short-term, rural-based circulation and permanent urban migration among Paamese to Port Vila. A major reversal of mobility is unlikely in the future. The reasons why are indicated. 相似文献

Various styles of "male love" occurring in the 19th century are introduced. Locations and public ordinances relating to these styles of love are discussed. The development of the homosexual role is broached along with the question of whether attitudes and laws of the 19th century were responsible in part for the development of normative expectations for homosexuality which might in turn have repressed its growth. 相似文献
