Relations between infant–mother attachment security at 15 months and infants’ (N = 206) joint attention behaviors (a) with an experimenter at 8 and 15 months, and (b) with their mothers at 15 months were investigated. No concurrent or longitudinal relations were observed between attachment security and infants’ tendency to respond to an experimenter’s bids for joint attention. Higher levels of initiating joint attention with an experimenter at 15 months were associated with insecure‐avoidant attachment. Insecure‐avoidant attachment was also associated with lower scores for initiating high‐level joint attention behaviors (pointing, showing, and giving) with the mother at age 15 months. The fact that security‐related differences in initiating joint attention with an experimenter were observed only once the attachment relationship was consolidated suggests that (a) attachment security may influence infants’ active engagement with new social partners, and (b) insecure‐avoidant infants may compensate for reduced social contact with the caregiver by initiating more interaction with other social partners. 相似文献

Drawing on two qualitative studies which looked at diet, weight and health from a social class perspective, we use Bourdieu's theory of habitus to help explain the different food and eating practices undertaken by families with young teenagers. Whilst the families displayed considerable reflexivity when making decisions about what to eat on a daily basis, the analysis highlighted that everyday behaviours are still bounded by distinctions of taste, according to social position. The paper includes an examination of the relationships between different forms of capital and whether form or functionality is prioritised within families. We show the importance of temporal frameworks when interpreting classed food and eating practices. 相似文献

A firm's two‐product bundling decision is examined when the supply of one product is limited and consumer valuations are normally distSteckeributed. The firm can choose to sell products separately and/or through a bundle. We find that the impact of limited supply on a firm's bundling decision depends on the correlation between the consumer valuations of the two products as well as the symmetry level of the two products in terms of their attractiveness (how much they are valued by consumers). When the valuation correlation is high and the symmetry level of the two products is low, limited supply can drive bundling. When the valuation correlation is low or the symmetry level is high, limited supply can drive no bundling. When the attractiveness of both products are low or the valuation correlation is very high, limited supply has no impact on a firm's bundling decision: The firm should not bundle for all supply levels. This study offers a new driver for product bundling: the limited supply of a product. The existing bundling literature suggests that a firm should bundle symmetric products that have a low consumer valuation correlation, when bundling is driven by consumer valuation heterogeneity reduction. In contrast, when bundling is driven by limited supply, a firm should bundle asymmetric products with a high consumer valuation correlation. The benefit of supply‐driven bundling depends on the severity of supply limitation. When supply limitation is moderate, bundling creates value by expanding the market of the less attractive product. When supply limitation is severe, bundling enables a firm to extract a higher margin from the less attractive product. 相似文献

The principles of critical science for policy research are outlined and one research project is used as a case study. The
study was intentionally designed to facilitate changes that would positively influence the economic well-being of children
from divorced families. The project uses the critical science processes of public dialogue about child support guidelines
for purposes of collaborative problem solving. The normative theories of procedural and distributive justice are used to guide
the research reporting. The project contributes to changes in the practices of estimating the income needs of children, changes
in estimating the relative monetary contributions of their parents, and proposed legislation and modifications in the state
child support guidelines.

The purpose of this study was to conduct a cost-benefit analysis of three Drug Court programs in Kentucky for two groups of Drug Court participants: program graduates and program terminators. The economic benefits of the Drug Court programs were estimated relative to a comparison group of individuals who were assessed for the Drug Court programs, but did not enter the programs. This study highlights important factors in estimating the costs and the economic benefits of a Drug Court program. Results indicated that, particularly for graduates, Drug Court involvement was associated with reductions in incarceration, mental health services, and legal costs, as well as increases in earnings and child support payments. Net benefits and benefit–cost ratios for each program are presented and policy implications are discussed. 相似文献
