Sensitive research issues call for anonymous questionnaires. This makes accurately matching pretests with posttests difficult or impossible. Various subject-generated coding schemes have been developed, but their accuracy has been unknown. This anonymous study, with 745 students, used subject-generated coding to match pretests with posttests. The matching was verified for accuracy with the use of a collateral, anonymous, sticker identification system. The coding system was able to accurately match 75.2% of all the pretest-posttest pairs. An additional 22.1% of the pairs were left unmatched and only 2.7% were matched incorrectly. Subject-generated coding systems can be very effective where confidentiality is important to protect. 相似文献

Millions of people have become refugees or been displaced within Afghanistan during 17 years of war within the country. Conversations with women in a camp for the displaced reveal what it means for women to lose their homes, especially in the context of ongoing instability and conflict. Sections discuss homelessness in Kabul, linking psycho-social and practical needs, coping with dislocation, stability and land ownership, mobility and security, family breakdown, temporary and permanent settlements, and meeting needs versus creating dependency. The author concludes that among people displaced from their homes for so many years, their physical and spiritual homes nonetheless remain inseparable from their lives. It is important to maintain the individual notion of home if life is to be worth living and hope retained. Relief agencies must help in an appropriate manner and to an appropriate extent. Oxfam has been working beyond the refugee camps, in a return to the city of Kabul, since July 1995. When this article was written, the NGO was involved in a joint venture to restore the piped water supply which, like the electricity supply, was looted and damaged. It also plans to distribute plastic sheeting for use as roofs and floor covering during the winter. Oxfam currently plans discreet activities rather than an integrated approach. 相似文献

"This article seeks to bring the ?urban' back into immigration research. Each immigrant receiving area has its own particular group of newcomers, and the economic and political structures of the immigrant receiving areas are also distinctive. Those structures are not all determining, as immigrant trajectories are shaped by the interaction between distinctive urban institutions and the specific characteristics of the relevant ethnic groups. But in the last analysis, the urban context makes a difference, as this study shows by examining the leading [U.S.] immigrant destinations--New York and Los Angeles." 相似文献

A measure of range of ability is used to profile the 85-years-old-and-older (oldest old) population, including the highly disabled institutional population. This new measure uses two new questions available in the 1990 Decennial Census concerning a self-care limitation and a mobility limitation as well as the usual question concerning a work limitation. In addition to examining the extent of disability among the oldest old, the article examines the extent of care potentially available in the household as well as the economic characteristics of this age group. It is also profiled in terms of relevant personal characteristics, including age, gender, marital status, race, ethnicity, rural residence, education, and employment. A key question addressed is the need for help or care among the oldest old and how various long-term care proposals would meet such needs. A careful analysis of this unique and growing population is necessary to both allay fears of the cost of care or help as well as to dispel stereotypes of this age group as frail and dependent, and in need of institutional care. 相似文献

Second generation decline? Children of immigrants,past and present--a reconsideration 总被引:1,自引:0,他引:1
"Is the contemporary second generation on the road to the upward mobility and assimilation that in retrospect characterized the second generation of earlier immigrations? Or are the American economic context and the racial origins of today's immigration likely to result in a much less favorable future for the contemporary second generation? While several recent papers have argued for the latter position, we suspect they are too pessimistic. We briefly review the second generation upward mobility in the past and then turn to the crucial comparisons between past and present." 相似文献

Rethinking assimilation theory for a new era of immigration 总被引:6,自引:0,他引:6
"We argue that assimilation theory has not lost its utility for the study of contemporary immigration to the United States. In making our case, we review critically the canonical account of assimilation provided by Milton Gordon and others; we refer to Shibutani and Kwan's theory of ethnic stratification to suggest some directions to take in reformulating assimilation theory. We also examine some of the arguments frequently made to distinguish between the earlier mass immigration of Europeans and the immigration of the contemporary era and find them to be inconclusive. Finally, we sift through some of the evidence about the socioeconomic and residential assimilation of recent immigrant groups. Though the record is clearly mixed, we find evidence consistent with the view that assimilation is taking place, albeit unevenly." 相似文献

Little documentation exists regarding the functioning of formalized adolescent groups as drug abuse prevention agents. Two studies are described that were conducted at high schools whose students are at high risk for drug abuse. Twenty-one schools were randomly assigned to one of three conditions: (a) standard care, (b) classroom drug abuse education only, or (c) classroom plus school-as-community. Results of the first study indicated that the school-as-community component--which involved weekly meetings and periodic events at seven schools--was implemented as planned, drug abused focused, and perceived as productive in discouraging drug abuse. In the second study, staff in the classroom plus school-as-community condition self-reported involvement in the greatest number of community activities across the school year, compared with staff from the other two conditions. These two studies support the feasibility of formalized groups of high-risk youth to promote drug-free events. 相似文献

In 1931, Nevada legalized casino gambling, an act which allowed its gaming industry to develop. Because many jurisdictions outside Nevada are now embracing legalized gambling as a path to a brighter economic future and because this proliferation presents Nevada with new challenges and opportunities, it is a good time to review the Nevada experience. Here, the focus is on gaming revenues and gaming tax collections during the 1945–95 period. We find that the growth rate of Nevada's gaming industry has slowed over time, with the relative importance of gaming in the Nevada economy peaking in the late 1970's. The Nevada economy has since been gradually diversifying, something which will increasingly pressure Nevadans to look for government revenue sources other than gaming if current levels of government services are to be maintained. 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

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.
