Development of knowledge acquisition techniques known as automated discovery systems has occurred in deep and narrow domains of knowledge. Automated discovery is the generation of new knowledge by a computer system on its own, without the help of another knowledge source. This paper describes research and validation of an automated discovery system for a wide and shallow domain—business management. The system continues recent advances in expert systems research which have enhanced cognitive mapping, a problem formulation tool. The system perceives the behavior of distal variables in the environment through probabilistic cues-to-causality, and generates previously unknown hypotheses by aggregating the probabilities into a single criterion of causal relatedness. The system is validated against the source code of a simulated managerial environment, and causal relationships posited by decision makers experienced in the play of the gaming simulator.  相似文献

Mission statements have been adopted nearly universally in nonprofit organizations. Their ubiquity is based on a presumption that a well‐designed mission statement is linked to better organizational performance because it provides a framework for decision making, influence over staff and volunteer motivation, and a mechanism for signaling organizational legitimacy to stakeholders. Despite collective confidence in mission statement utility, the relationship between mission statements and performance has received minimal attention. In this exploratory study we measured several attributes of mission statements in women's rights nonprofit organizations, with particular attention to the degree to which the statement focuses on organizational purpose and the relationship between focus and several measures of organization financial performance. The findings indicated that mission statements with a more focused geographic scope were associated with lower overhead ratios. In contrast, mission statements that identified more target client groups were associated with larger one‐year increases in contribution. Despite the statistical significance, the relationships were weak, calling into question common assumptions about the importance of the mission statement to a nonprofit organization.  相似文献

Homelessness services and policy have historically tended to be organised by an explicitly conditional logic, wherein people experiencing homelessness must prove their “housing readiness” before accessing settled housing. This model has been robustly challenged in recent decades by “housing-led” approaches that ostensibly eschew conditionality and prioritise the rapid rehousing of people experiencing homelessness. Various countries now include housing-led approaches in the national policy frameworks, including Australia, which overhauled its approach to homelessness in 2008, and Scotland, where a housing-led approach is supported by a legal right to housing for homeless households. Notwithstanding this policy shift, conditionality remains an enduring feature of responses to homelessness in both jurisdictions. This paper sheds light on this phenomenon by comparing the Australian experience with that of Scotland. We demonstrate how conditionality remains a feature of both jurisdictions; however, there is greater effort in Scotland to identify and minimise conditionality, whereas in Australia it is able to persist relatively unchallenged. We conclude with some reflections on what Australia can learn from Scotland’s relative success, highlighting the importance of a national-level policy framework and an adequate affordable housing supply.  相似文献

In societies in which families are highly integrated, the education of family members may be linked to survival. Such may be the case in Taiwan, where there are large gaps in levels of education across generations and high levels of resource transfers between family members. This study employs 14 years of longitudinal data from Taiwan to examine the combined effects of the education of older adults and their adult children on the mortality outcomes of older adults. We use nested Gompertz hazard models to evaluate the importance of the education of an older adult and his or her highest-educated child after controlling for socioeconomic, demographic, and health characteristics at baseline. To gain further insight, we fit additional models based on the sample stratified by whether older adults report serious diseases at baseline. The results indicate that the educational levels of both older adults and children are associated with older adult mortality, but children's education appears more important when we examine the mortality of only those older adults who already report a serious disease. This finding suggests that there may be different roles for education in the onset versus the progression of a health problem that may lead to death.  相似文献

Family ties have wide-ranging consequences for health, for better and for worse. This decade review uses a life course perspective to frame significant advances in research on the effects of family structure and transitions (e.g., marital status) and family dynamics and quality (e.g., emotional support from family members) on health across the life course. Significant advances include the linking of childhood family experiences to health at older ages, identification of biosocial processes that explain how family ties influence health throughout life, research on social contagion showing how family members influence one another's health, and attention to diversity in family and health dynamics, including gender, sexuality, socioeconomic, and racial diversity. Significant innovations in methods include dyadic and family-level analysis and causal inference strategies. The review concludes by identifying directions for future research on families and health, advocating for a “family biography” framework to guide future research, and calling for more research specifically designed to assess policies that affect families and their health from childhood into later life.  相似文献

In this paper, we examine whether investments in higher education have contributed to changes in occupational inequality by focusing on the impact of college completion rates on movement into desirable occupations between 1983 and 2002. Since forces generating inequality vary by gender, race, and ethnicity, we examine trends for white, black, and Hispanic men and women in our study. Utilizing Ordinary Least Squares Regression on data from 20 Current Population Surveys, we find a modest decrease in both gender and racial inequality in access to desirable occupations and an increase in inequality between Hispanics and members of the other groups. College completion accounts for the progress made by white women and for the declines among Hispanic men. It does not explain changes for African Americans, either between men and women or when compared to whites.  相似文献

Using unique administrative data from the state of Georgia, this paper investigates women’s decisions to exit the labor market upon the birth of a child. Exits rates and their changes over time varies dramatically between married and single women giving birth. Only the pattern among single, less educated women can be considered consistent with changing labor force participation rates of women over the period of analysis. Potential policy implications of these changes are discussed.  相似文献
