Recent studies have attempted to understand the processes involved in joint attention because of its relevance to both atypical and normal development. Data from a recent study of young children with autism suggests that performance on a delay nonmatch to sample (DNMS) task associated with ventromedial prefrontal functions, but not an A‐not‐B/delayed response task associated with dorsolateral prefrontal cortex, was related to joint attention skills (Dawson et al., 2002). Recent research also suggests that joint attention is associated with dorsalmedial brain systems linked to self‐monitoring (Mundy, 2003). This study investigated the relations among joint attention, DNMS, and self‐recognition performance in a longitudinal study of 39 normally developing toddlers from 14 to 18 months. The results indicated that development on the DNMS and self‐recognition tasks, but not a means end task, predicted joint attention at 18 months. Further analysis showed that the model was only significant for initiating joint attention (IJA). The implications of these results for the neuro‐development of IJA are discussed.  相似文献

TOWARD A SYNTHESIS OF FEMINIST AND DEMOGRAPHIC PERSPECTIVES ON FERTILITY   总被引:1,自引:0,他引:1  
In explaining fertility and reproduction and emerging patterns of childbearing, both demographers and feminists have centered their thinking on women's status (economic and social), women's changing roles and life experiences (increased labor force participation, increased availability of reproductive options, declining marriage rates in many parts of the industrialized world, and the centrality of women to development), and women as agents in micro- and macrolevel changes in family, fertility, and economic change. Although demography has recently begun to integrate feminist perspectives into fertility explanations, there is not yet a synthesis of feminist theoretical insights with demographic questions. Drawing from recent thinking on global and national political and policy challenges in the less and more developed worlds, to the epistemological shifts in knowledge of reproduction/mothering, to changes in the technologies of reproduction, this article moves toward an integration of feminist and demographic perspectives on fertility.
…far from the economic dependence of women working in the interests of motherhood, it is the steadily acting cause of a pathological maternity and a declining birthrate.

We consider the problem of estimating the scale parameter of an exponential or a gamma distribution under squared error loss when the scale parameter θ is known to be greater than some fixed value θ0. Natural estimators in this setting include truncated linear functions of the sufficient statistic. Such estimators are typically inadmissible, but explicit improvements seem difficult to find. Some are presented here. A particularly interesting finding is that estimators which are admissible in the untruncated problem which take values only in the interior of the truncated parameter space are found to be inadmissible for the truncated problem.  相似文献

The authors examined nineteen nonprofit performing arts organizations, investigating the distribution of influence among organizational members, the grouping of volunteers and staff in organizational structures, and the effectiveness of the organizations. The organizations' effectiveness was assessed using multiple performance indicators. The analysis revealed five groupings or configurations of influence, which correlated to the organizations exhibiting the highest and lowest levels of organizational effectiveness. The authors conclude that a variety of structures are associated with good performance but structural dysfunctions are associated with organizational failure, and that members' commitment to an organization's structure is an important element of success.  相似文献

The Planning and Statistical Department of the State Family Planning Commission of China in July 1988 implemented a fertility and birth control survey in China on 2.16 million married women ages 15-57 using stratified, systematic, clustered, and non-proportionate sampling. 3 questionnaires were used: household, married women, and sample unit covering basic status, family planning status, general characteristics of pregnancy and contraception, population flow, deaths since 1981, and socioeconomic status. The authors suggest several international cooperative research projects including: design of fertility and contraception survey; Chinese population growth; Chinese population dynamics; dynamics of marital and family status; fertility; contraception and birth control; mortality; migration; status of the nationalities of China; population development; regional fertility status; and others. Data from the survey will be available in June 1989.  相似文献

Research on family therapy training has produced very little data regarding the kinds of trainees that do best in family therapy training programs. This study attempts to provide some rough and preliminary data on that issue. One hundred and seventy trainees, drawn from seven different structural!strategic training experiences, were evaluated as to how much they learned by taking the Family Therapy Assessment Exercise pre- and posttraining. Their performance was correlated using a hierarchical regression analysis with a number of trainee variables such as amount of conjugal family experience, amount of experience doing family or individual therapy, or prior knowledge of family therapy. The results indicate that, as predicted, conjugal family experience was positively related, and prior knowledge was negatively related to performance. Prior experience doing individual therapy was also positively related to performance.  相似文献

Working with a treatment and observing team at the same time, behind the oneway mirror, offers a variety of ways to: (a) generate multiple realities; (b) work with two different models of family therapy simultaneously; and (c) provide feedback on the teams' own roles, rules and group process. The process that 6 trainees and two supervisors used with T and O teams to examine their own coevolution as a therapeutic system using the Milan model of family therapy and Ericksonian hypnotherapy is described. The article concludes with a discussion of the advantages and pitfalls of this type of dual supervision.  相似文献

An estimated 200,000-500,000 men, women, and children work in prostitution in the Philippines in a variety of venues, including brothels, nightclubs, pubs, massage parlors, and other legitimate entertainment establishments. Few, however, are voluntary prostitutes. Many people who work as prostitutes have been recruited from the provinces, kept in conditions similar to slavery, and forced to earn money from prostitution to pay for their transportation, board, and lodging. Many prostitutes work in urban centers and tourist resorts in the countryside. During the 1970s, then President Ferdinand Marcos promoted tourism as a major industry, effectively marketing attractive Filipinas to tourists. Sex tourism has flourished in the country ever since. Thousands of prostitutes are also located in Olongapo and Angeles, 2 cities north of Manila, from where they serve the sexual desires of US military personnel. The presence of US military personnel in the Philippines has always been associated with prostitution. The country's social hygiene centers, prostitutes in Manila and Davao, and AIDS education are briefly discussed.  相似文献
