The authors develop an econometric model to examine the impact of migration on fertility in Greece in the period 1968-1986. In the model, the fertility equation is considered within a simultaneous equation system, and international migration is included as an explanatory factor of both fertility and per capita income.

The internalization of clinical nursing research values, norms, and attitudes via orientation and research development, along with the introduction of research tools (artifacts), constitutes the birthing phase of the acculturation process. The development of unit and individual research agendas and the implementation of research rounds illustrates a "bonding phase," in that nurses are bonding or weaving research into the fabric of their clinical practice. The final phase, stabilization, occurs when clinical nursing research is core to clinical nursing practice as illustrated by rewards or sanctions via performance evaluations, and provisions for release time for research participation.  相似文献

Not with standing human rights linkages, migrants and refugees are often on the periphery of effective international protection. State sovereignty and self-regarding notions of community are used to deny or dilute substantive and procedural guarantees. Recently, even non- discrimination as a fundamental principle has been questioned, as has the system of refugee protection. This article located both migrants and refugees squarely within the human rights context, contrasting both inalienable rights with the demands of sovereignty, and juxtaposing the 2 in a context of existing and developing international standards. Migration and refugee flows will go on, and the developed world, in particular, must address the consequences - legal, humanitarian, socioeconomic, and cultural. Racism and institutional denials of basic rights daily challenge the common interest. This article shows how the law must evolve, responding coherently to contemporary problems, if the structure of rights and freedoms is to be maintained.  相似文献

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

"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

1. It is important to examine client and staff satisfaction with the RN case management (RNCM) model to enhance the quality of care in psychiatric settings. 2. Ninety-two percent of clients surveyed ranked the RNCM care as "excellent" or "above average." Clients valued most the humanistic role of the RNCM and repeatedly commented on the importance of the nurse being caring, genuine, and supportive. 3. RNCMs expressed high satisfaction with their role, which they described as collaborative with the psychiatrist, yet also professional and independent. Psychiatrists expressed a high degree of confidence that clients were receiving excellent care by competent nurse professionals.  相似文献
