"While a generalized utility maximization approach to migration decisionmaking is not innovative, the principal extensions of this paper involve the search for an instrument capable of measuring changes in utility levels consistent with all preferences (i.e., with all forms of utility functions), requiring only data on observed behaviour. Our approach is to construct a Location-Specific Utility Index (LSUI), whose component variables serve as proxies for the arguments in [U.S.] households' utility functions.... The testable hypothesis is formulated as follows: Assuming constant household preferences and expansion of the household's feasible set over time, the household's utility level is greater following the migration decision.... The results are compared with the households' migration decisions. The empirical evidence shows that migration may reasonably be modelled as a consumption activity by households to maximize utility."

The Community Prevention Trial was 5-year effort to reduce alcohol-involved injuries and death through a comprehensive program of community awareness and policy activities. The three experimental communities were of approximately 100,000 population each (one in Northern California, one in Southern California, and one in South Carolina). Matched comparison communities were used for each experimental community. This article describes the evaluation approach used in a program that sought to change environmental factors not a specific population or target group. This approach demanded unique evaluation approaches for determining overall community aggregate effects, that is, distal outcomes, as well as changes in key mediating variables, that is, process effects. The problem of trending and lagged effects of community prevention programs are discussed. 相似文献

The long-term effectiveness of Drug Abuse Resistance Education (D.A.R.E.) was assessed by contrasting drug use and other D.A.R.E.-related attitudinal latent variables among 356 twelfth-grade students who had received the program in the 6th grade with 264 others who did not receive it. A prior study of these subjects when they were in 9th grade had shown no significant differences. A follow-up survey in 12th grade assessed central D.A.R.E. concepts such as self-esteem, police bonds, delay of experimentation with drugs, and various forms of drug use. Although the authors found no relationship between prior D.A.R.E. participation and later alcohol use, cigarette smoking, or marijuana use in 12th grade, there was a significant relationship between earlier D.A.R.E. participation and less use of illegal, more deviant drugs (e.g., inhalants, cocaine, LSD) in a development sample but not in a validation sample. Findings from the two studies suggest a possible sleeper effect for D.A.R.E. in reference to the use of harder drugs, especially among teenage males. 相似文献

Stinchfield R Cassuto N Winters K Latimer W 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1997,13(1):25-48
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

This paper presents three different poverty standards. A first approach takes the disposable income as an indicator of poverty. A second approach uses the Leyden approach. Finally an aggregate index of deprivation, based on the observation of consumption events, is constructed through a particular econometric procedure proposed by Desai and Shah (1988). These alternative measures are then compared on a sample composed of 6380 Belgian households. Such an analysis can be expected to provide some further insight into the problem of measuring poverty, which has been the subject of a recent controversial debate.We thank the participants of the Second Annual Meeting of the European Society for Population Economics, June 23–25, 1988, Mannheim (FRG), L.

Over the past several decades, there has been a plethora of proposals that were developed in response to the ongoing debate on how best to solve the problems of the American health care delivery system. In the past decade, calls for modification of our health system have become even more resonant, as measures to control rising costs were unsuccessful and access to basic services was diminished for many Americans. The most recent addition to the list of proposals for modifying the health care system is the American Health Security Act of 1993, introduced by President Clinton in September 1993. This article will examine the position of the Clinton Administration on health reform and the core elements of the reform package. 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

Will a large-scale migration of Russians to the Russian Republic take place over the current decade?
Dunlop JB 《The International migration review》1993,27(3):605-629
The author discusses "the likely scale of in-migration from the other former union republics into the Russian Republic over the remainder of this decade....I believe that during the 1990s there will be continued mass in-migration into Russia from the seven former union republics of Central Asia and the Transcaucasus....I also foresee that Russians will continue to leave such inhospitable milieux as southern Kazakhstan and western Ukraine." 相似文献
