文章基于新疆塔城哈尔墩社区的田野调查,从空间嵌入的视角对该民族互嵌型社区形成和发展的历程,即社区的生命史进行描述和分析。调查发现,该社区的生命史反映了清末以来各民族人口向塔城迁移汇聚的历史进程,是塔城各民族由“小聚居”逐渐走向“嵌入”历程的一个缩影。文章认为,应加强对历史上形成并延续至当下的民族互嵌型社区的调查和研究,以空间嵌入为“起手棋”,关照社区生命史与族群生活史的互构,并将社区的小历史嵌入于整体社会的大历史中,进而从“国家—区域—地方”三个维度的互动中对这类社区的形成与发展进行解释。  相似文献

The authors describe the socioeconomic characteristics and fertility patterns of female immigrants from Latin America to the United States, with a focus on reasons for fertility differentials. "Using the one per cent public use sample from the 1970 and 1980 United States census, we first compare changes in socio economic characteristics from 1970 to 1980, and then examine the determinants of fertility of female immigrants to the United States, aged 16-49, from four Latin American areas or countries of birth.... The findings...suggest that there are direct effects of demographic, assimilation, and socioeconomic variables beyond those mediated by the variables in each of these sets. Further, regardless of the model, the effect of the clusters of demographic characteristics is most apparent. Age categories and marital status are the strongest indexed determinants of immigrant fertility.... The effect of education and employment is strong. Among assimilation variables, duration of residence and language ability are significant determinants of Hispanic immigrant fertility." (SUMMARY IN FRE AND SPA)  相似文献

This article reviews scientific and other literature during the 1990s that links migration and mobility with the spread of sexually transmitted diseases (STDs), including HIV/AIDS. The focus is on key population groups linked to the spread of HIV and STDs in West and Central Africa: migrant laborers, truck drivers, itinerant traders, commercial sex workers (CSWs), and refugees. Countries with high emigration and immigration tend to have high levels of HIV infection, with the exception of Senegal. The main destination of immigrants are Senegal, Nigeria, and Cote d'Ivoire in West Africa and Cameroon, Congo, Gabon, and Congo in Central Africa. The risk of infection and the spread of HIV is variable among migrants. There is little in the literature that substantiates hypotheses about the strong association between migration and HIV-positive status. Information is needed on the duration, frequency of return visits, living conditions, sexual activities with multiple partners, and information before departure, along the routes, at final destination, and at the time of returns. Action-based research in five West African countries (Burkina Faso, Cote d'Ivoire, Mali, Niger, and Senegal) should produce results in late 1998. Comparable studies in Central Africa are unknown. Regional studies should be complemented by local studies. Prevention would benefit from studies on the relative size of these five population groups by geographic location.  相似文献

The purposes of this study were to examine the prevalence of gambling among youth, compare rates of gambling between 1992 and 1995, and determine what levels of gambling frequency may be considered common and uncommon. The two samples included 122,700 Minnesota public school students in the 6th, 9th, and 12th grades in 1992; and 75,900 9th and 12th grade students in 1995. Students were administered the Minnesota Student Survey, a 126-item, anonymous, self-administered, paper-and-pencil questionnaire that inquires about multiple content domains, including gambling behaviors. The same questionnaire, with minor revisions to the gambling items, was administered in both 1992 and 1995 to students in their classrooms by the Minnesota Department of Education. There were slight decreases in overall gambling rates from 1992 to 1995. The majority of students gambled at least once during the past year. However, most did not play any game on a weekly/daily rate and did not report any problems associated with their gambling. Gender, grade, and race effects were found for gambling frequency. Boys gambled more often than girls, and 9th and 12th grade students gambled more often than 6th grade students. Asian American and White students reported lower rates of gambling frequency than Mexican/Latin American, African American, and American Indian students. From a statistical standpoint (i.e., beyond the 97.7 percentile), it may be considered in the uncommon range for girls to play two or more games at a weekly/daily rate, and for boys to play four or more games at a weekly/daily rate. Variables associated with gambling frequency included antisocial behavior, gender, and alcohol use frequency. Although the finding that gambling did not increase from 1992 to 1995 is encouraging, this is the first generation of youth to be exposed to widespread accessability to gambling venues and gambling advertising and it will be important to continue monitoring the prevalence of youth gambling.  相似文献
