The purpose of this article is to review evidence concerning the joint impact of family characteristics and child care experiences in understanding children's development. Although child care experiences are related to children's development across a variety of domains, family characteristics, particularly socioeconomic status and parenting quality, are typically stronger predictors of children's outcomes. An important implication of these findings is that high-quality child care experiences are likely to have stronger effects on children who are at risk of poorer outcomes because of less optimal family environments; evidence from experimental and nonexperimental studies generally supports this conclusion. From a policy perspective, an important goal for future research is to identify subgroups of families within the heterogeneous low-income population that are in particular need of relatively more intensive services and to develop effective interventions that are tailored to their needs.  相似文献

The authors assessed the relative contributions of social support and interest‐occupation congruence in job satisfaction and tenure. Congruence predicted 13% of the variance in job satisfaction for men, but it was not a significant predictor of job satisfaction for women. Social support accounted for 10% of the variance in job satisfaction for women but was not a significant predictor for men. Neither congruence nor social support predicted tenure. Implications for vocational counseling are discussed.  相似文献

The current research investigated whether intraverbals would emerge following auditory tact instruction. Participants were first taught to tact auditory stimuli by providing the name of the item or animal that produces the sound (e.g., saying “eagle” when presented with the recording of an eagle cawing). Following test probes for simple intraverbals as well as intraverbal categorization participants were taught to tact what each auditory stimulus is (e.g., saying “caw” when presented with the recording of an eagle cawing). Following both tact instructional phases, the effects of an auditory imagining instruction procedure on target intraverbals were examined. Results indicate that following both tact instructional phases, intraverbals increased for three of four participants. Auditory imagining instruction was sufficient for two of four participants to reach mastery criterion, and two of four participants needed some direct instruction. Low covariation between simple intraverbal and categorization was also observed. Functional interdependence between tacts and intraverbals and the possible role of a conditioned hearing response are discussed.  相似文献

The purpose of this project was to demonstrate untrained vocal requests in three adults with severe developmental disabilities. Specifically, we evaluated whether a history of reinforced relational responding would give rise to untrained vocal requests for novel items. Participants were first taught to request preferred items using their category names. They were then taught conditional discriminations between pictures of preferred items that were categorically related. Finally, participants were tested for their abilities to request items that had not been originally presented during request training, using their category names. All participants demonstrated untrained requests, and for some participants, changes in the mand repertoire were accompanied by changes in the tact repertoire. Some participants also showed generalization of skills across settings.  相似文献

Multicultural Meanings of Social Support among Immigrants and Refugees   总被引:1,自引:1,他引:0  
Canada continues to be a prominent immigrant and refugee‐receiving country in worldwide migration, resettlement, and search for refuge, yet there is a gap in our understanding of these newcomers’ views of the specific meanings of social support and their support needs and resources. The purpose of this study was to understand the meanings of social support for immigrants and refugees in Canada, and to explore the types and adequacy of formal supports. Individual interviews were conducted with 60 service providers and policymakers initially (Phase 1), and 120 immigrants and refugees (60 Chinese, 60 Somali) in the second phase. The implications of these findings were elicited in group interviews (Phase 3) of policy decision‐makers, advocates, service providers, and managers. This investigation revealed many interrelated challenges facing refugees and immigrants such as language difficulties, inadequate information on services, poor health, racism, needs for retraining, rejection of foreign qualifications, unemployment, social isolation, social insecurity, dwindling social networks, and family conflicts. The study also illuminated culturally and socio‐economically determined perceptions of social support and support‐seeking strategies. Limited personal resources and dwindling social networks are an impediment to coping with integration and settlement challenges. In many cases, newcomers’ efforts to seek help are thwarted by systemic obstacles. Newcomers experienced extensive unmet support needs, which service providers cannot adequately meet due to bureaucratic and resource constraints. Policies in various sectors that affect the lives of immigrants and refugees are inadequate for bridging their support deficiencies. These support gaps hinder the successful settlement and integration of newcomers. Policies and programs fostering culturally relevant support, and inter‐sectoral collaboration among organizations addressing the support needs of immigrants and refugees are timely.  相似文献

To successfully understand spoken language, listeners need to determine how words within sentences relate to one another. Although the ability to compute relationships between word categories is known to develop early in life, little research has been conducted on infants' early sensitivity to subcategorical dependencies, such as those evoked by grammatical gender (where the article form is dictated by the noun's gender). This study therefore examines whether French‐learning 18‐month‐olds track such relationships. Using the Visual Fixation Procedure, infants were presented with article–noun sequences in which the gender‐marked article either matched (e.g., laFEM poussetteFEM “the stroller”) or mismatched (e.g., leMASC poussetteFEM) the gender of the noun. A clear preference for correct over incorrect co‐occurrences was observed, suggesting that by 18 months of age, children's storage and access of words is sufficiently sophisticated to include the means to track subcategorical dependencies. This early sensitivity to gender information may be greatly beneficial for constraining lexical access during online language processing.  相似文献

This article uses nine case studies of global supply chains (GSCs) in Southern Cone countries to explore the extent to which economic and social upgrading are linked and spread from lead firms to their supply chain. While economic and social upgrading are found in lead firm segments throughout the case studies, the impacts on suppliers are varied. Pattern groupings enable the authors to develop a three‐part typology of development in GSCs, in the light of which they consider the roles of public policies, company behaviour and social actors in addressing developmental outcomes for GSC lead firms and suppliers.  相似文献

There have been few studies of the concept of double jeopardy as it pertains to the effects of gender and aging on occupational outcomes. This research examines the utility of this concept in the field of film acting, traditionally a gender-integrated occupation. The results confirm significant negative effects of being female and being older on the number of film roles received by actors and their average star presence. Moreover, the gendered effects of aging on the career opportunities of actors have diminished somewhat over time with respect to number of film roles but not with respect to star presence.  相似文献
