A growing body of literature indicates that families with adopted children seek mental health care for the adoptive and other family members more frequently and for different reasons than biologically-bound families. This paper addresses the struggles and corrective strategies for adoptive families at various levels of their development.  相似文献

Limit expressions (as the dimension p ← ∞ ) are derived for the relative risk of the James-Stein estimator and its positive-part version. The limit is simple to evaluate, and gives the amount of improvement in risk that is possible. The technique used is to bound the risk, both above and below. with bounds that converge to the same limit. For the James-Stein estimator these bounds are simple to calculate, and are quite accurate even for moderate dimensions.  相似文献

The paper focuses on an employee’s perception of his or her own labour market outcome. It proposes that the basic earnings function, by adopting an approach that ignores perception effects, is likely to result in biased results that will fail to understand the complexities of the wage distribution. The paper uses an orthodox job search framework to illustrate the nature of this problem and then adapts the model to take onboard the theory of cognitive dissonance. The search model indicates how workers may adopt a coping strategy in order to reduce the disutility associated with the wage underpayment that develops. Then, by modelling cognitive dissonance, the paper highlights the weaknesses of using purely human capital proxies to understand labour market outcome. The analysis goes some way to explaining why individuals with equivalent human capital investment can have disparate earnings profiles.  相似文献

The encyclopedic inventory of the first half of the twentieth century, “Anthropology Today”, published in 1953, gave little inkling that within a few decades developing trends in social theory, in field experience, in electronic data processing, and in mathematics would combine to bring to prominence a distinctive theoretical approach using a quite formal network model for social systems. Now, sophisticated mathematics and computer programming permit sophisticated network models — networks seen as sets of links, networks seen as generated structures, and networks seen as flow processes. Although network thinking has shown a dramatic rise from the “Anthropology Today” of 1953 to the current anthropology of 1978, it is predicted to soar in the next quarter century, much of the weighty burden of network analysis having been lifted from us by ever more rapid electronic data processing.  相似文献

"Cross-sectional and longitudinal variations in rates of intergroup marriage [in the United States] have often been used as indicators of assimilation for minority groups. This article demonstrates that both types of comparisons can give misleading results when census data are used for calculating intermarriage rates without restrictions. Census data include immigrants who married abroad (IMAs) in the enumeration. The inclusion of these individuals in the study of intermarriage inevitably biases the level of minority inmarriage upward, making cross-sectional and longitudinal comparisons of intermarriage rates for groups with different levels of IMAs inappropriate. Cumulation of IMAs also inflates the inmarriage rates of older cohorts, leading to a misimpression of increasing outmarriage among younger cohorts. These problems are illustrated for several Asian groups using 1980 Public Use Microdata Sample data for California. Alternative approaches for remedying the problem are proposed and their different implications for assimilation theory and research are discussed."  相似文献

Current Manufacturing Support Systems (MSS), such as Computer-aided Manufacturing (CAM) Systems, Computer-aided Design (CAD) Systems, Computer Integrated Manufacturing (CIM) Systems, Material Resource Planning (MRP) Systems, and Manufacturing Accounting Control (MAC) Systems, are mostly independent systems that are operated in limited decision spaces, provide mainly formal and quantitative information, and thus pursue a goal of local optimization. To assist modern manufacturing in meeting the needs for integration, communication, collaboration, and decision making, we introduce the concept of integrating MSS with Distributed Group Support System (DGSS) into a Distributed Manufacturing Support System (DMSS). A rigorous system design approach is taken to model the manufacturing information requirements from a global perspective and pattern decision making processes within the structural (organizational design) and infrastructural (information system design) elements of manufacturing. The result is a conceptual DMSS design that provides an intelligent interface, accommodates incremental manufacturing integration, offers controllable message exchange facilities, and allows configurable communication networks.  相似文献
