Estimation of nonlinear functions of a multinomial parameter vector is necessary in many categorical data problems. The first and second order jackknife are explored for the purpose of reduction of bias. The second order jackknife of a function g(.) of a multinomial parameter is shown to be asymptotically normal if all second order partials ?2g( p )?dpi?pj obey a Hölder condition with exponent α>1/2. Numerical results for the estimation of the log odds ratio in a 2times2 table demonstrate the efficiency of the jackknife method for reduction of mean-square-error and the construction of approximate confidence intervals. 相似文献

Action theory's substantive image of social organization, theory building strategy, and methodological tenets are compared with those of interactionism. Despite polemics to the contrary, action and interaction concepts denote a similar image of social organization and personality. As is argued, the principle difference between the two perspectives revolves around the issue of the most appropriate theory building and methodological strategy. The ontological implications of this fact are examined and found not to justify the continued partitioning of social theory into antagonistic metaphysical camps. 相似文献

If the sex-age structure of the population is equilibrated, observed marriage patterns are assumed to reflect preferred mate selections. With regard to age, these preferences can be expressed in terms of the probabilities of unmarried persons of given ages marrying persons of various ages. To study the situation of unequilibrated sexes, these probabilities can be used to compute, for each combination of ages of groom and bride, the expected number of grooms and the expected number of brides. If either of these numbers exceeds the other, the corresponding sex is in a "marriage squeeze." The comparison among the expected number of grooms, that of brides, and the observed number of marriages supplies information on the effects of the squeeze.In Australia, marriage statistics of 1949 were considered to reflect preferred selections. In 1958, men of most ages were in a squeeze. As a consequence, some relatively younger and older men did not get married, and some relatively younger and older women improved their chances of marriage in the year under consideration. 291-299. 相似文献

Manifold factors have been identified as causal mechanisms in social change, but an important one–temporality–has been neglected. Temporality is the social time that characterizes any society, and that social time is consequential for the rate and direction of change. The three dimensions of temporality are temporal pattern, temporal orientation, and temporal perspective. The differences between the Japanese and Chinese along these three dimensions help explain their differential responses to the 19th century Western challenge. Specifically, two propositions are examined in the light of the historical data: a society's temporality limits the range of adaptive responses to new circumstances, and the symbols of social time act as a mechanism of social control. 相似文献

Support provided by family and friends may influence the extent to which older women who are primary caregivers for a spouse with dementia adhere to an exercise routine. The current study reports on qualitative interviews with 30 older female caregivers taking part in an exercise intervention regarding the support they received for their exercise goals. Results indicate that nearly all women received some level of verbal encouragement from family and friends, though far fewer had exercise partners or someone to stay with their husbands while they exercised. To reflect the wide variation observed in the amount of exercise support received and needed by caregivers, a typology of support situations was constructed as follows: Self-reliant, Well-supported, Under-supported, and Superfluous support. Implications for future exercise interventions targeting this population are discussed. 相似文献

Does coaching need a philosphically substantiated ethics? On the foundation of a systemic value oriented imperative for coachingThe general claim that coaches have to take responsibility for their clients is in contrast to the low interest in scientific discussion about ethics in coaching. One of the reasons for that seems to be the fact that this discussion is dominated by systemic thinking and its conviction that ethical aspects should be discussed as matter of contingency. From a philosophical point of view we can realize that this statement contains many ethical implications. Concerning a further development of coaching theory the author discusses these implications with regard to philosophical concepts of Kant, Habermas, Prange, Heidegger, Bauman and the Dalai Lama leading to the suggestion that systemic thinking should be more based on value orientation. On this theoretical grounds an ethical coaching imperative can be formulated with regard to the “categorical imperative” of Kant. 相似文献

Food insufficiency is a significant problem in the United States, and poor African American women with children are at especially high risk. An inadequate household food supply can potentially affect the well-being of household members, but it is difficult to distinguish the effects of food insufficiency from risk factors for poor health that are also common among the food insufficient, such as poverty. We examined food insufficiency and physical and mental health among African American and white women (n = 676) who were welfare recipients in 1997. Controlling for common risk factors, women who reported food insufficiency in both 1997 and 1998 were more likely to report fair or poor health at the later date. Food insufficiency in 1998 was significantly associated with meeting the diagnostic screening criteria for recent major depression. Food insufficiency at both times and in 1998 only was related to women's sense of mastery. These findings add to growing evidence that household food insufficiency is associated with poor physical and mental health. 相似文献
