Incomplete moments are used to characterize income inequality and provide the basis for interdistributional Lorenz curves. Four measures of interdistributional inequality are considered and seen to be related to an interdistributional welfare interpretation. Based upon these measures, there has been a significant secular decline in interdistributional inequality between blacks and whites over the past 30 years. 相似文献

Sub-national and cross-national variations in the age difference between spouses are investigated with data from the World Fertility Survey relating to 29 developing countries. Substantial variation within and between countries is evident. Analysis suggests that the relative age of prospective spouses is a factor taken into account in the marriage market. Observed variation in the age difference, within and between countries, cannot be explained as the simple by-product of the random matching of independently determined distributions of men's and women's ages at marriage. Certain age differences are avoided, others chosen more frequently. Preferred age differences appear to differ in the societies studied, however, and this variation can be directly interpreted in terms of two sets of factors: kinship structure and women's roles. The analysis also suggests that demographic determinants of the age difference, in particular age constraints on the pool of possible matches, are of less importance in explaining societal variations than are social structural factors. 相似文献

Research suggests that non-linguistic sequence learning abilities are an important contributor to language development (Conway, Bauernschmidt, Huang, & Pisoni, 2010). The current study investigated visual sequence learning as a possible predictor of vocabulary development in infants. Fifty-eight 8.5-month-old infants were presented with a three-location spatiotemporal sequence of multi-colored geometric shapes. Early language skills were assessed using the MacArthur-Bates CDI. Analyses of children's reaction times to the stimuli suggest that the extent to which infants demonstrated learning was significantly correlated with their vocabulary comprehension at the time of test and with their gestural comprehension abilities 5 months later. These findings suggest that visual sequence learning may have both domain-general and domain-specific associations with language learning. 相似文献

The boxplot is an effective data-visualization tool useful in diverse applications and disciplines. Although more sophisticated graphical methods exist, the boxplot remains relevant due to its simplicity, interpretability, and usefulness, even in the age of big data. This article highlights the origins and developments of the boxplot that is now widely viewed as an industry standard as well as its inherent limitations when dealing with data from skewed distributions, particularly when detecting outliers. The proposed Ratio-Skewed boxplot is shown to be practical and suitable for outlier labeling across several parametric distributions. 相似文献

The child welfare system indicates that evidence of successful completion of parenting classes is instrumental in determining whether parents are actively engaged in the process of permanency planning. Such classes vary in length and intensity with topics ranging from "How to Raise Healthy Families" to "How to Discipline Your Child." Two social workers (one white and one black), who initially disagreed about the format of a parenting class, chronicle their efforts to collaborate and create a class format that recognizes the psychosocial and, more specifically, the cultural influences inherent in facilitating these classes. The juxtaposition of the clinical concepts of projection and projective identification are evaluated against the backdrop of the social concepts of empowerment and diversity. 相似文献

This article presents a consensus-building initiative to develop a statewide research agenda that responds to the needs of Illinois's child welfare community. Researchers conducted this process through a university-community partnership to engage those interested in child welfare services. The process and findings resulted in a living document that will guide child welfare research throughout the state. Findings of the inquiry suggest that the development of best practice models may be one of the most important contributions research can make to practice. 相似文献

The prevalence of diagnosed cumulative trauma disorders (CTD) within the workforce comes at a high price for employers burdened with financial losses from missed work and worker's compensation costs. Research has focused primarily on the impact of CTD on the worker role within the workplace, overlooking the impact on roles across multiple environments [24,35,54]. Furthermore, the influence of CTD on life roles of a spouse has not been examined. This single case study illustrated the experience of CTD within a marital relationship through the use of grounded theory. Results indicated that adaptations to CTD symptoms were least altering to the established routines and roles of the couple. With progression of symptoms, the spouse without symptoms was relied on more heavily for adaptations to manage pain. The results of this study indicate that occupational therapists must examine the client's valued roles and incorporate the family into intervention strategies. 相似文献
