The paper presents a comparative analysis of the relationship between rural-urban migration and fertility in Korea, Mexico, and Cameroon. Using an autoregressive model, the results show a significant rural-urban migration adaptation effect in Korea and Mexico, a reduction of 2.57 and 1.45 children during the entire childbearing period, respectively, when compared to a rural stayer, even after the effect of selection has been controlled. Rural-urban migration has a very small impact on fertility in Cameroon. The unexpected result for Cameroon is due to the fact that the fertility-increasing effect of urban residency on the improved supply conditions of births, such as reduced infertility, offsets the fertility-depressing effect of urban residency on the demand for births. As a result of the adaptation to urban fertility norms, the number of country-wide births was reduced significantly in Mexico and Korea over the time periods studied.  相似文献

The purpose of the present study was to gather empirical data to examine the usefulness of an intriguing training technique called “bad therapy”. The technique, developed by Lang (1980, 1982), is utilized in a role-play setting for experienced therapists who are having difficulty with specific clients showing little improvement. The therapist is instructed to disregard his or her usual style of treatment, and instead, within a role-play format with a colleague who plays the part of a client, to try an alternative style of treatment. This new treatment, termed “bad therapy”, instructs the therapist to try to make the client worse rather than better. Interestingly, reports from both the role-play therapist and client indicate that the “bad therapy” session was considered more beneficial than the therapist's usual mode of treatment. As well as empirically investigating Lang's assertion, the present study also attempted to look at different perspectives of bad therapy. Is “bad therapy” a directive to be harmful and destructive, or is it a suggestion to be more daring and to take more risks? Subjects were 56 therapists who formed twenty eight pairs of therapist-client dyads. First, each pair conducted a “session” where the therapist performed his or her typical therapy. Then, therapists in one group (N= 11) were given directives to try to make their clients worse rather than better (“destructive” set), while therapists in another group (N=11) were told to say and do things that they wished to, but never dared (“daring” set). Finally, six therapists were told to simply repeat their usual type of therapy (“control” set). Results indicated that clients perceived the destructive and daring groups differently with the daring group being perceived more favourably, yet more authoritarian. Similarly, therapists perceived the daring and control groups more positively than the destructive group. The results are discussed in terms of training techniques and current trends in psychotherapy.  相似文献

Multivariate analysis is used to estimate a model of member participation in local union activities. A sample of 387 members of the UAW living in the Detroit area was drawn from the1961 Detroit Area Study: Work Group Influence and Political Participation. It was hypothesized that participation would be positively associated with level of schooling, current wages, seniority, skilled jobs, job dissatisfaction, dissatisfaction with the local union, desire for another job, commitment to the labor movement, and getting along with others. OLS and Logit estimation techniques were used and support was found for all hypotheses except those related to wage levels and seniority.  相似文献

Data from U.S. Forest Service timber auctions are used to test Vickrey's original proposition that sealed-bid and open auctions yield equal revenue. Models for the high-bid in an auction are specified and estimated using three different procedures: ordinary least squares, two stage least squares, and maximum likelihood. The second two procedures include a second equation which accounts for the Forest Service's auction choice and therefore control for selection bias. These two procedures, which unlike ordinary least squares yield consistent estimators, imply a statistically and economically insignificant difference in high-bids between sealed-bid and open auctions.  相似文献

Recent material is surveyed concerning the foundations of statistical models, the definition and logic of statistical inference, and the additives used in various applications of theories of inference. This background is then used to compare structural/structured models [Fraser 1966, 1968, 1979] and pivotal models [Barnard 1974, 1981]; the models are found to be identical except for nomencalture and basic justification which supports the structural format. An outline is given of the development of the structural/structured model and of the corresponding mode of inference. The recent pivotal methods of analysis are assessed with this development as background.  相似文献

Shame remains largely a hidden phenomenon in the treatment of couples. It can manifest itself as a determining factor in events ranging from entrenched blaming to missed appointments. Although there is a growing body of literature on individual shame dynamics and, to a lesser extent, on couple and family shame dynamics, there is little written on how to incorporate these theories into treatment. This paper offers working definitions of shame, proposes a systemic definition of shame as seen in couples, reviews the literature on coule shame dynamics, and explores issues of therapeutic stance and treatment techniques in working with shame in couples therapy.  相似文献
