China's "tidal wave" of migrant labor: what can we learn from Mexican undocumented migration to the United States? 总被引:1,自引:0,他引:1
Roberts KD 《The International migration review》1997,31(2):249-293
"The purpose of this article is to place Chinese labor migration from agriculture within the context of the literature on labor mobility in developing countries by comparing it to undocumented Mexican migration to the United States. The similarities fall within three general areas: the migration process, the economic and social position of migrants at their destination, and the agrarian structure and process of agricultural development that has perpetuated circular migration. The last section of the article draws upon these similarities, as well as differences between the two countries, to generate predictions concerning the development of labor migration in China." 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

US theoretical models of assimilation of ethnic groups within a larger culture usually assume a unilinear, unidimensional process, which is simplistic, does not account for the persistence of ethnicity, and oversimplifies the process of social change. The argument is advanced that ethnic identity is both primordial and situational (a private sense that is self-maintaining, cumulative, deepening, and self-affirming). Typically, a person has one primary ethnic identity, but where ethnic boundaries overlap, there is instrumental identity. Chinese in Thailand mostly adopt Thai values, speak the Thai language, go to Thai schools, join Thai associations, and celebrate Thai religious festivals. Their secondary identity as Chinese is integrated into their associations with other Chinese and in the home through the use of the Chinese language. Their Chinese identity appears also in ancestor worship. There are symbiotic relationships between native Thais and Chinese Thais along class lines. The Chinese are known to have great financial and economic resources, while the Thais have political and administrative control. These differences with the power elites separate the Chinese from the Thais and interfere with assimilation. The power is balanced. If the Chinese gained in political and administrative power, the balance would be upset, and the interests of both groups would be threatened. The view of Whitten and Whitten acknowledges that individuals and groups act to make the best of the situation and are not merely victims of social forces. Actions are maintained and resisted. The important consideration in theory-building is not the terms of assimilation but the terms specifying the conduct of the group as a whole and as individuals in daily social interactions. The theoretical discussion focuses on border crossings, the Skinner view of the Chinese, bilingualism and cultural education, socioeconomic organizations, occupational differences, and religion, tradition, and ethnic identification. 相似文献

This study is a contribution to the development of family resource management scales, specifically financial management scales. Principal axis factor analysis, with varimax rotation, is used to assess underlying relationships in 23 family resource management variables related to time and money resources. Reliability and content, construct, and criterion-related validity of the scales are assessed. Two scales that are reliable and have some degree of validity are developed: frequency of financial problems and frequency of financial management. The scales could be used in future research, teaching, or counseling to organize financial management concepts.Preparation of this research was supported in part by the Illinois Agricultural Experiment Station. Data were collected in conjunction with the cooperative regional research project NC-182, Family Resource Utilization as a Factor in Determining Economic Well-Being of Rural Families. Cooperating states are Arizona, California, Illinois, Indiana, Iowa, Kansas, Michigan, and Minnesota.She received her Ph.D. from the University of Illinois; her current research interests include gender roles, family financial management, and economic well-being.Her current research interests include family financial management and consumer bankruptcy.

Path analysis is used to examine the causal relationships among selected objective and subjective factors associated with a household's expectation of future financial condition. Results indicate that respondents who perceive the effect of changes in the external environment on their own household's financial condition as positive are younger, have higher net worth, perceive more internal control over their situation, and report that most of the changes in the external environment are positive. Respondents who are younger, have higher income, perceive more internal control over their situation, and believe the effect of changes in the external environment on their household's financial condition are positive are more likely to be optimistic about their financial future. It is important that educators and financial advisors recognize the significant role perception of being in control plays in determining expectations of future financial condition.Journal Paper No. J-15256 of the Iowa Agriculture and Home Economics Experiment Station, Project No. 2809.

The plight of people who lack access to health care has captured national attention and led to a number of proposals to remedy the problem. The authors look at three types of proposals being advanced--"pro-competition" plans, "pay-or-play" plans, and a national health care system--and find that they fail to address adequately the pressing needs of two groups of the poor: women of childbearing age and elderly women. 相似文献
