We suggest a model that describes how counterfactuals are constructed and justified. The model can describe how counterfactual beliefs are updated given the unfolding of actual history. It also allows us to examine the use of counterfactuals in prediction, and to show that a logically omniscient reasoner gains nothing from using counterfactuals for prediction. 相似文献

Abstract Family work in dual-earner families has been studied extensively, but the focus has been primarily on household tasks and child care, neglecting the component of health care behavior. In this paper, I introduce scales to study the performance of family health care behaviors in dual-earner families. The items assess topics such as who arranged and accompanied family members to health care appointments, who left work early or took time off from work for health care, and who handled the paperwork of medical expenses. The sample consisted of 174 married women employed in health care and education. The study results indicate that the health care scales are reliable. They are also not highly correlated with demographic variables that might affect the utility of the scales to examine how health care behaviors are linked to other family work. 相似文献

The purpose of this research was to investigate whether people vary in their willingness to listen and whether this variable has any relationship to dogmatism, receiver apprehension, Self-Perceived Communication Competence (SPCC), or communication apprehension. A refined version of the Willingness-To-Listen (WTL) instrument was used to test these relationships. The results indicated that the WTL scale is a reliable and valid measure of an individual's habitual propensity to listen. WTL was found to be positively related to communication skills and negatively related to receiver apprehension, sender-based communication apprehension, and dogmatism. 相似文献

Infant adoption policy and practices are laden with potential ethical dilemmas for adoption professionals, state and federal government, and society in general. Putative father registries raise new ethical issues in the provision of adoption services and the rights and roles of birthfathers. Birthfathers have relatively little power in the policy arena and the power differential between the parties in an adoption is evident. Administrators and practitioners at all levels of practice have an obligation to see that birthfathers are treated fairly and with dignity. This article examines the issues related to the use of putative father registries and the ethical implications regarding birthfather rights. 相似文献

Divorce remains one of the main challenges facing American families today. Previous studies have shown that the risk of divorce is influenced by many factors, including spouses' characteristics and the types of neighborhoods in which they live. This study extends previous work by examining the association between household size and divorce rate at the county level using 1990 and 2000 county-level data. The results show that household size is negatively and significantly associated with divorce rate in both 1990 and 2000, regardless of the region of residence. That effect was stronger in 2000, where household size appeared as the second most significant correlate of divorce rate among all other variables considered in the linear multiple regression analysis. Such findings suggest that household size acts as a social capital variable which helps to maintain family structure, thus reducing the risk of union dissolution. 相似文献

The perceived wisdom in the social work education community, based on empirical research from the 1990s and the early part of this century, says that the master of social work (MSW) degree is not competitive with the master of business administration or the master of public administration to obtain top-level administration jobs in nonprofit agencies. This article reviews recent information on hiring preferences of board chairs that provides new hope that the MSW degree with a concentration in management or administration is perceived as a viable and useful degree for top-level positions in human services agencies. Thus, current board chairs are more inclined to value the MSW than administrators and academics from years past. The reason is that the values of social workers are seen as quite valuable in the current environment. 相似文献

What can service firms do to improve their ability to offer new services? In this paper we argue that new service development success results from building a competence in the management of service development resources and routines. We conceptualize new service development competence as a multidimensional, second‐order latent construct that is represented by a system of four interrelated and complementary dimensions: (1) formalized new service development processes, (2) market acuity, (3) new service development strategy, and (4) information technology use and experience. We hypothesize that the growth of new service development competence is related to improved new service development performance. Using structural equations modeling, we analyze survey data from 166 retail banks and report three key empirical findings. First, we show that the four hypothesized dimensions are statistically significant in defining new service development competence. Second, contrary to conventional wisdom in new product development, we find that formalized processes play a lesser role in the success of new service development compared with the other three dimensions. Instead, market acuity—which captures the firm's ability to see the competitive environment clearly and to anticipate and respond to customers' evolving needs and wants—was the most important new service development competence indicator. Finally, we demonstrate the positive effect of new service development competence on new service development performance and show that new service development competence is also significantly related to business‐level performance. Together, our empirical results suggest that complementary benefits arise from the adoption of a more holistic approach to the management of new service development at the program level. 相似文献
