This paper extends the micro-level empirical literature on migration decision making by investigating the manner in which husbands' and wives' subjective place utility expectations jointly feed into migration decisions in a low-income country. The authors use expectational data relating to four place utility dimensions and stated migration intentions of 376 village-resident Egyptian couples to test alternative decision models. An ordinal probit estimation technique is employed. The results of the analyses support the hypothesis of husband dominance in migration decisions in this context. The authors conclude with a discussion of the implications of the paper for further theoretical refinement and for migration survey design in this and other developing countries.Dr. McDevitt is a Research Associate of the Carolina Population Center, The University of North Carolina at Chapel Hill.

This study surveyed 975 undergraduates attending a large East Coast university during the spring semester of the 1987/88 academic year. A convenience sample of predominantly black students (94%) participated. Overall, knowledge of basic AIDS-related facts was satisfactory. Raw scores on the 25-item knowledge scale ranged from 7 to 25, with a mean of 20.5 (82%) and a mode of 22 (88%). Selected questions on how HIV is not transmitted, however, posed some problems for respondents. Less than 30% of respondents knew that the AIDs virus was not transmitted by insects; less than 80% knew that AIDS was not transmitted on toilet seats, through blood donations, kissing, and coughing. The survey also asked students whether they had ever engaged in certain behaviors that put them at risk of HIV infection. Approximately 17% of respondents had experienced anal intercourse, 6.5% reported use of heroin, 32.6% reported having had multiple sex partners, and 16% had been treated for a sexually transmitted disease. Students who reported engaging in high-risk behaviors had statistically significant lower mean knowledge scores than those who reported not engaging in those same high-risk behaviors. Results of the study support the need to increase efforts to deliver AIDS information specifically targeted to individuals who may be engaged in high-risk behaviors. Special health education programs must be designed to focus attention on risk behaviors (ie, unprotected anal intercourse) instead of risk groups (ie, homosexual and bisexual males).  相似文献

In this first part an econometric model describing the sequences of live births to individual couples is developed and estimated, using data for a sample of married women in rural French communes during the period 1749–1789. The main methodological objective is to devise a means of controlling for unobserved heterogeneities that result in the endogeneity of variables describing a couple's accumulated demographic experience. Without such controls it is not possible to secure unbiased estimates of responses to familial demographic events, such as the births and deaths of children. Such estimates are sought here as indirect indicators of the existence and nature of deliberate fertility control.Un modèle économétrique, décrivant la suite des naissances vivantes d'un couple donné, est développé et estimé dans cette première partie, en utilisant des données sur un échantillon de femmes mariées dans des communes rurales françaises durant la période 1749–1789. Le principal objectif méthodologique est de fournir un moyen de contrôler l'hétérogénéité non observée qui résulte de variables endogènes décrivant l'expérience cumulative d'un couple. Sans un tel contrôle il n'est pas possible d'obtenir des estimations sans biais de l'effet d'événements démographiques, tels que les naissances et les décès d'enfants. De tels estimateurs sont recherchés ici en vue de fournir des indications indirectes sur l'exercice et la nature d'une prévention des naissances délibérée.

In Germany there is broad consensus that efficient implementation of programme objectives requires cooperative political and administrative structures as the basis for realizing measures, activities and mobilization and revitalization processes deemed necessary by the neighbourhood. Therefore neighbourhood management is regarded as a critical tool for handling the tasks and reaching the targets associated with integrative district development. However, this tool is interpreted and utilized in a different manner. This is reflected not only in the labels (district, area or neighbourhood management), but more emphatically in the various organizational forms employed, ranging from individual officials equipped with specific authority to complex structures involving different levels of municipal control and operation. This article presents the neighbourhood management concept developed and implemented in the framework of the ‘Socially Integrative City’.  相似文献

Using data from the 1990 and 2000 U.S. Census of Population and Housing, we examine five social and economic characteristics of individuals and households living on reservations in Arizona and New Mexico that have a casino to those that do not. This research differs in two ways from previous studies that have attempted to assess the social and economic impacts of Indian gaming. First, the unit of observation and analysis is the reservation, not a tribe. A focus on reservations allows us to assess the role casinos play in “place-based” economic development. Second, since reservations and tribes are not coterminous, we seek to differentiate the effects of casinos on the Indian population living on reservations from the effects for all reservation residents (Indians and others). The results show that casino gambling is associated with improvements in social and economic welfare for both the Indian and non-Indian populations alike. However, Indian gaming did not contribute to positive outcomes in all cases. Indeed, the effects of gaming are filtered through a myriad of structural and cultural contexts that shape who wins and who loses when a casino opens on a reservation. The implications of Indian gaming for economic development are discussed.  相似文献

Since its publishing in 1997, Charles Mills's The Racial Contract has changed the way in which sociologists think about and practice the study of race and racism. Nevertheless, it is my belief that this work has not received its rightful place among other canonical works within the field. This article, then, is an attempt to show the utility and creativity within which this work has been used by a number of scholars within the critical race discourse. For it is this body of work that holds the most promise for not only opening new doors in the study of race and racism, but also for liberating us from the racial contract under which we live.  相似文献

We consider a general class of mixed models, where the individual parameter vector is composed of a linear function of the population parameter vector plus an individual random effects vector. The linear function can vary for the different individuals. We show that the search for optimal designs for the estimation of the population parameter vector can be restricted to the class of group-wise identical designs, i.e., for each of the groups defined by the different linear functions only one individual elementary design has to be optimized. A way to apply the result to non-linear mixed models is described.  相似文献

Two recursive schemes are presented for the calculation of the probabilityP(g(x)S n (x)≤h(x) for allx∈®), whereS n is the empirical distribution function of a sample from a continuous distribution andh, g are continuous and isotone functions. The results are specialized for the calculation of the distribution and the corresponding percentage points of the test statistic of the two-sided Kolmogorov-Smirnov one sample test. The schemes allow the calculation of the power of the test too. Finally an extensive tabulation of percentage points for the Kolmogorov-Smirnov test is given.  相似文献
