An experiment was conducted to assess the effect of using "markall that apply" question instructions on survey reporting aspart of the field test for the Second Follow-up of the NationalEducation Longitudinal Study of 1988 Eighth Graders (NELS:88).Mark-all-that-apply instructions were compared with instructionsasking respondents to indicate "yes" or "no" to each responseoption on responses to three items dispersed throughout thequestionnaire and consisting of different topics and numbersof response options. For the three items, significantly fewerresponse options were selected with the mark-all-that-applyinstructions than with the yes/no instructions, but becauseexternal validity criteria were not available, overreportingto the yes/no instructions cannot be ruled out. Instructiondependentprimacy effects, predicted under the hypothesis that respondentswould engage in more superficial processing when given the mark-all-that-applyinstructions, were not found. 相似文献

Kadioglu A 《International migration (Geneva, Switzerland)》1994,32(4):533-560
Findings are based on a sample of four types of Turkish women affected by migration: 1) pioneer women who emigrated on their own (33 persons); 2) followers with wage work experience, who joined or left with husbands (44 persons); 3) followers without wage work experience (39 persons); and 4) women left behind when husbands migrated (45 persons). These women are compared to a non-migrant control group (54 persons). Sample surveys were conducted in three sites, which varied in levels of industrial development, economic diversification, and urbanization (Ankara, Kisehir, and eight rural villages in the province of Kisehir). The sample includes returnees registered with the Social Insurance Institute and persons located by the chain inquiry method. Prior research supports the importance of including typologies based on family types, marriage types, levels of education, and experience with wage work. This study confirms that pioneer women were more likely to have romantic marriages, to have nuclear families, to have higher educational levels, and to have prior wage work. Analysis of the 116 women with migration experience shows that 75% migrated during 1968-74. 22% migrated after 1980. 51% were returnees during 1983-85, and many received retirement benefits. Almost 65% spent 10 or more years abroad. 56% were aged under 24 years. 85% were married at the time of emigration. 61% viewed their migration experiences as improving their maturity and ability to handle affairs compared to nonmigrant women. 88% became housewives after returning. 27% of return migrants and 82% of nonmigrants had never had their own bank accounts. 69% of return migrants and only 22% of nonmigrants reported movement outside the home without permission. 63% of migrants and 39% of nonmigrants would cast political votes independently of their husbands. Migrating women exercised more independent behavior but retained traditional responsibility for housework. The greatest differences were between women with wage work and women without or with migrating husbands. Followers without wage work were the most disadvantaged. Migration is viewed as a significant factor in determining gender roles among Turkish women. 相似文献

I. Nelson Rose J.D. B.A. 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1995,11(1):15-33
This article examines the current trends of proliferation of commercial gaming, especially in the United States, in the context of the third wave of legalization of gambling that has been experienced since the founding of the nation. The author looks at the historic foundations of the spread of casino-style gambling, and notes the types of casino gaming that have led the way in the current expansion. He also points out why it is reasonable to expect that this wave too may come crashing down, as general acceptance of wide-spread casino gaming in America may indeed be short-lived.Gambling and the Law® is a registered trademark of I.

This paper describes a model which relates fertility to partner availability, an aspect of relative cohort size. Partner availability is affected by the tendency for males to reproduce at a later age than females. For women born at a time of rising birth rates, there is a shortage of slightly older men as potential partners. Women born when birthrates are falling enjoy a surplus of older men from which to choose. This model is believed to be the first non-linear demographic feedback model involving feedbacks through marriage squeezes in which empirically estimated values of the parameters imply persistent limit cycles. The deterministic model makes births in each five-year period a function of births in previous five-year periods. The form of the function is chosen to model the effect of partner availability upon entry into reproductive relationships, and therefore on age-specific fertility. Marriage rates are not modeled directly. The model was developed from data for more than a century from England and Wales, New Zealand, and the US. The demographic transition is modeled with a logistic function and age-specific fertility rates are estimated using lognormal distributions. The stepwise inclusion of a partner availability estimate in the model showed that it accounts for 29% of otherwise unexplained variance. Projected future births stabilize in sustained or limit cycles with periods a little longer than 40 years, and amplitudes of at least 7% of the mean. The necessary conditions for cycle persistence are outlined on a graph of maximum and minimum fertility parameters. 相似文献

Measuring credibility of compensatory preference statements when trade-offs are interval determined 总被引:1,自引:0,他引:1
This paper studies how an overall fuzzy preference relation can be constructed in the compensatory context of the simple additive difference model, when imprecision on the trade-offs has to be taken into account. Three credibility indices of preferences are analysed and illustrated by a numerical example. Arguments are presented supporting the use of the third index, for which an interesting transitivity property (which was an open problem) is proved. 相似文献

Drawing households and other living spaces in the process of assessment and psychotherapy 总被引:1,自引:1,他引:0
This paper introduces a drawing technique developed by the author for use in the assessment and treatment of individuals and families. The client is invited to draw a floor plan of his or her home or apartment, or an aerial view of un outdoor area. The drawing is then discussed and considered as a means of understanding critical elements of the experience of life space. The material derived is discussed from the eerspectives of family systems, psychodynamic, and abuse treatment theories, with special reference to notions of family structure, boundary, the self, and memory. Emphasis is placed on the actual physical layout of the home, as well as the subjective experience of it. Applications of the drawing technique for exploring memories are illustrated. Case examples are presented from clinical trials with children and adults in residential treatment, inpatient, and outpatient settings.The Heller Financial Corporation generously supports the development of household and spatial drawings for treatment and prevention. A version of this paper was presented at the 43rd Annual Meeting of the American Association of Psychiatric Services for Children, New Orleans, February 26, 1992. The author wishes to thank Robert B. Bloom, Ph.D., Excutive Director of JCB, for supporting the development of ideas and techniques discribed in this paper. 相似文献

International migration: demographic and socioeconomic consequences in the United Kingdom and Europe
Coleman DA 《The International migration review》1995,29(1):155-206
"This article evaluates the consequences of international migration since World War II, with particular reference to Great Britain. It emphasizes the substantial differences between the origins and responses to immigration in the United Kingdom and that of the rest of Western Europe." It is found that "people of non-European origin from Commonwealth countries have predominated in postwar immigration to the United Kingdom. That migration neutralized the previously dominant pattern of emigration and increased U.K. population by about 3 million people through immigration and higher fertility, with only slight effects upon the age distribution." 相似文献

A cultural economy perspective on service sector migration in the global city: the case of Hong Kong
This article argues that in order to fully understand the geography of labour migration to global cities, it is necessary to consider economic forces in conjunction with mediating socio-cultural influences. Support for this argument is based on an examination of the pattern of migration to Hong Kong, a city which plays a significant role in the world economy.
Reported here are the results of an analysis of recently released 1996 by-census data, and the authors' interviews with foreign domestic workers in Hong Kong. These findings have shown that highly skilled immigrant workers were drawn largely from developed countries, the main sources of inward investment in this city, while less skilled immigrants were drawn from less developed neighbouring labour markets.
While the geographical pattern of immigration followed broadly that predicted from Hong Kong's position in the world economy, the results have revealed that cultural influences such as language and social networks are also important in shaping the economic roles of migrant workers. 相似文献

There is some concern in Australia that immigration contributes to a widening of its current account deficit. Several cross-section studies have found that migrant households have a lower saving rate than the local born households. In conjunction with a well-known national income identity that the current account deficit is equal to the excess of investment over saving, such findings have been interpreted by many to mean that the migrants contribute to increasing the level of foreign liabilities at a rate greater than that by the local-born.
However, it should be realized that immigration impacts on the economy in a complex way through various demand and supply side channels. Its direct and chain effects on such variables as the current account are spread over both the short and the long term. These effects are neither unidirectional nor always easy to isolate. The final outcome, which is the sum total of all the effects, is uncertain, and cannot be fully understood from a knowledge of cross-sectional saving performance alone.
This article utilizes aggregate time series data to investigate the relationship between the current account and immigration. It finds that although an increase in net migration tends to raise the current account deficit, the longer term effect of immigration on the current account is negligible. 相似文献
