This study focused on the communicative interaction of fathers with their Head Start children and the relationship of fathers' and children's communicative skills and child behavior problems early and late in the school year. The results indicate a relationship between children's communicative competence and social behavior. The structural models for externalizing and internalizing behavior confirm the hypothesis that father communication is linked to child communication skills and child communication is linked to behavior problems. The findings also suggest that children's communicative competence may have an ongoing direct effect on children's social behavior that transcends the impact that earlier social behavior has on later social behavior. 相似文献

A national longitudinal database (NELS: 88-94, 1996) was used to examine the occupational aspiration patterns, vocational preparation, and work-related experiences of adolescents who were either work-bound or college-bound two years after their initial transition from high school to work or postsecondary education. Adolescents' career choice and behavior patterns were analyzed at two separate points. Grades 8 and 10 achievement profiles of work- and unemployment-bound youths were similar; both groups had significantly lower achievement scores than college-bound youths. Socioeconomic status (SES) had considerable influence on determining both occupational aspirations and postsecondary transition status. Two-thirds of all young adults who were work-bound or unemployed/out of the work force were in the lowest two SES groups. Adolescents in the highest SES were four times more likely to be college-bound. Educational aspiration was a more accurate predictor of postsecondary status than occupational aspiration. Work-bound youths did not engage in higher levels of school-based work preparation than college-bound peers. Occupational aspirations of college-bound youth were relatively stable over the two-year period (from Grade 8 to 10), while those of noncollege-bound youths were more volatile. The prestige levels of occupational aspirations, for all youth, were relatively established by early adolescence and did not change significantly over time. 相似文献

Abstract While critics have often asserted that museology is underdeveloped as a discipline and lacks a “core literature,” no empirical evidence has been introduced to support this claim. A citation analysis of journal articles and books published over the past several years shows clear evidence that a core literature is in fact evolving in the field. Highly‐productive and influential authors are easily identifiable, as are seminal works that have received large numbers of citations by other authors. The majority of those highly‐cited works belong to the discipline of museology itself, and sizable numbers of influential publications cluster around key unifying themes. 相似文献

The Food and Drug Administration (FDA) uses scientific procedures to evaluate regulated firms’ new product applications. Much of its basic intellectual resources, in the form of scientific advisory committee members, come from research institutions. Regulated firms may seek connections to the FDA advisory committee members to affect the regulatory approval process. However, individual linkages may fail. The use of Scientific Advisory Boards (SAB) with multiple members provides redundant ties to the regulator, which means that the failure of each tie becomes less material. This paper is principally concerned with the firm's motivation to rebalance power imbalances rather than any actual regulatory outcomes. Controlling for alternative explanations, I find that dependence on the regulator is positively associated with the probability of having a SAB. Selected network diagrams add credibility to the hypothesis. 相似文献

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children’s pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of fathers’ early cognitive stimulation on early reading and math skills at 48 and 60 months. There were also two moderated effects: The effects of high levels of maternal stimulation at 24 months on early math and reading skills at 48 months were largest for children also receiving high levels of cognitive stimulation from their childcare providers. Implications for including fathers in studies of the home cognitive stimulation and strengthening the parent-childcare connection are discussed. 相似文献
