This paper is concerned with estimating the parameters of Tadikamalla-Johnson's LUdistributions based on the method of moments. Tables of the parameters of the LU distribution are given for selected values of skewness (0.0(0.05) 1.0(0.1)2.0) and for twenty values of kurtosis at intervals of 0.2. The construction and use of these tables is explained with a numerical example. 相似文献

We propose a randomized minima–maxima nomination (RMMN) sampling design for use in finite populations. We derive the first- and second-order inclusion probabilities for both with and without replacement variations of the design. The inclusion probabilities for the without replacement variation are derived using a non-homogeneous Markov process. The design is simple to implement and results in simple and easy to calculate estimators and variances. It generalizes maxima nomination sampling for use in finite populations and includes some other sampling designs as special cases. We provide some optimality results and show that, in the context of finite population sampling, maxima nomination sampling is not generally the optimum design to follow. We also show, through numerical examples and a case study, that the proposed design can result in significant improvements in efficiency compared to simple random sampling without replacement designs for a wide choice of population types. Finally, we describe a bootstrap method for choosing values of the design parameters. 相似文献

Longitudinal data from 293 Dutch couples were used to examine the association between conflict frequency and relationship quality across the transition to parenthood, which is known as one of the most challenging events in the early stages of marriage. More frequent conflict during pregnancy was related to lower levels of relationship quality across the transition to parenthood, and lower levels of relationship quality during pregnancy were associated with more frequent conflict across the transition to parenthood. A comparison of two models showed that frequent conflict is more likely to be a determinant than a consequence of lower relationship quality. The results suggest a complicated but identifiable association between conflict frequency and relationship quality that may inform the development and modification of primary interventions targeting new parents. 相似文献

In West Indian societies, the Chinese, as relative latecomers, provide an example of a minority group coping with a foreign culture and subject to assessment by earlier arrivants. They often appear only briefly in novels, but their presence contributes to pictures of ‘authentic’ village communities and to impressions of culturally and economically diverse urban centres. Despite their economic links with the communities in which they live, novelists depict them as existing outside the power relations of Creole societies which are determined largely by class and colour oppositions stemming from the experiences of slavery and colonialism. 相似文献

This article describes low-cost and tested procedures which may be used by the social work pracritioner-researcher for collection of data about what takes place in groups in natural setting. Some technical issues in uses of tapes of group sessions obtained by portable cassette recorders are explored. Content analysis as a research technique is explained and illustrations provided. Process analysis through measurement of such dimensions as frequency and initiator of speech is described. 相似文献

This article, drawing upon three approaches from comparativepolitical science, compares domestic violence politics in Russiawith Ukraine, Moldova, and Armenia. It suggests that foreignassistance, not without unintended consequences, holds the bestpromise for initiating reform. It also shows that there is nothingparticular about Russian culture that limits reform, especially,as activists can manipulate gender neo-traditionalism. Finally,the study suggests that institutionalized political channelsfor considering women's issues can facilitate feminist policy-makingwhen pushed by an autonomous women's movement. In conclusion,the article suggests that studying gender politics in non-Westerncontexts requires integrating comparative with internationaltheories. 相似文献

This article draws on institutional and ecological perspectives on work and organizations to develop a workplace level model of variation in voluntary counselor turnover rates across privately funded substance abuse treatment centers in the United States. Results show that participatory management structures reduce turnover rates principally by promoting organizational commitment. The analysis also tests hypotheses regarding the effects on turnover rates of other relevant theoretic domains of treatment center structure and organization. We discuss theoretical implications of the findings and suggest directions for future research. 相似文献

Ninety-one parents of 120 adopted Romanian children who were part of a longitudinal study were surveyed to determine perceptions
of their relationships with their children, their adoption experiences, and the children’s strengths. The Behavioral and Emotional
Rating Scale (BERS) was used and parents were easily able to rate their children’s emotional and behavioral strengths. Levels
of parent–child relationship satisfaction were the most consistent predictors of child emotional and behavioral strength.
The child’s age at the time of the survey was a significant predictor of strengths, indicating overall that younger children
had more perceived strengths. Parents identified fewer strengths among children with longer histories of institutional care.
The importance of a strong parent–child relationship and resilience after a history of early institutional care are discussed. 相似文献

Community-based participatory research (CBPR) has been posited as a promising methodology to address health concerns at the community level, including cancer disparities. However, the major criticism to this approach is the lack of scientific grounded evaluation methods to assess development and implementation of this type of research. This paper describes the process of development and implementation of a participatory evaluation framework within a CBPR program to reduce breast, cervical, and colorectal cancer disparities between African Americans and whites in Alabama and Mississippi as well as lessons learned. The participatory process involved community partners and academicians in a fluid process to identify common ground activities and outcomes. The logic model, a lay friendly approach, was used as the template and clearly outlined the steps to be taken in the evaluation process without sacrificing the rigorousness of the evaluation process. We have learned three major lessons in this process: (1) the importance of constant and open dialogue among partners; (2) flexibility to make changes in the evaluation plan and implementation; and (3) importance of evaluators playing the role of facilitators between the community and academicians. Despite the challenges, we offer a viable approach to evaluation of CBPR programs focusing on cancer disparities. 相似文献

Recent work on phonological variation largely supports the apparent‐time construct, though some change across an individual's lifespan is possible. But how much change is possible in an individual's grammar? How much is grammar affected by extended absence in a new, urban speech community? Social dialect surveys traditionally exclude individuals who have left their community for an extended period of time, under the assumption that dialect contact causes levelling or restructuring of the linguistic system. However, our ongoing work in a Caribbean speech community suggests that the kinds of changes that can affect grammatical variables are more constrained than we might think. Raw frequencies of vernacular variants may fluctuate, but language‐internal constraints persist. Drawing on recordings from Bequia we compare the group norms for absence of copula/auxiliary be in three villages. We show that ‘urban sojourners’– Bequians who have spent an extended period overseas – may sound very different from their stay‐at‐home peers, but close examination shows only superficial restructuring of their grammars. Overall frequencies of be absence may be dramatically reduced but the ranking of language‐internal constraints remains largely unchanged. These results reaffirm the validity of modelling variable rules in a community grammar, rather than as an aggregation of idiolectal norms. 相似文献
