Economic activities of families have important influences on processes of family development and family change over time. Knowledge of these special relations has expanded in recent years, as has the literature on the economics of family life as a general field. As a result, scholars and professionals in consumer studies and home economics need conceptual frameworks that organize areas of specific findings and identify specific issues for research. A conceptual framework which identifies four economic activities performed by families and six fundamental family development and family change processes is proposed. Then, a matrix of testable hypotheses is formulated, emphasizing economic activities as independent variables in family development and change. The matrix portrays the central roles economic influences play in contemporary family life, and suggests a complete, holistic understanding of these influences. The matrix also provides a conceptual guide to the design of empirical research and synthesis of findings on the economics–family development interface. 相似文献

Recent research shows that unsuccessful tender offers may affect target share returns for two years past the offer's announcement. This note examines target returns in the interim between the announcement and one year after the offer's withdrawal. Analyzing a recent sample of targets that did not get another bid in the year following a failed tender offer, this study reaches two conclusions. First, all of an offer's premium disappears by the time failure becomes public. Second, excess returns are zero in the post-failure year. An explanation that is based on the causes of the tender offers' failures is presented. 相似文献

This study emphasises the inter-relationships among family variables, nutrient intake and perceived health status among Malawian women. The sample consists of rural women residing in Zomba, Malawi, southern Africa. Data were collected from April to June 1993 on (1) family cohesion and adaptability, assessed by a modified version of Olson's FACES 11; (2) dietary intake using a modified food frequency questionnaire; and (3) a 24-item questionnaire on perceived health status, barriers to health and desired methods of communicating nutrition information in the village. The results indicated that Malawian rural women perceived their families as highly cohesive and adaptable. Diseases frequently identified as common in the family were not perceived as related to nutrition. Income significantly correlated with dietary adequacy. The study suggests that efforts to promote health and nutritional status should be directed at disease prevention and its ecological relationship with nutrition. Strategies for communicating nutrition information in rural Malawi are provided. 相似文献

We develop a state-of-the-art fraud prediction model using a machine learning approach. We demonstrate the value of combining domain knowledge and machine learning methods in model building. We select our model input based on existing accounting theories, but we differ from prior accounting research by using raw accounting numbers rather than financial ratios. We employ one of the most powerful machine learning methods, ensemble learning, rather than the commonly used method of logistic regression. To assess the performance of fraud prediction models, we introduce a new performance evaluation metric commonly used in ranking problems that is more appropriate for the fraud prediction task. Starting with an identical set of theory-motivated raw accounting numbers, we show that our new fraud prediction model outperforms two benchmark models by a large margin: the Dechow et al. logistic regression model based on financial ratios, and the Cecchini et al. support-vector-machine model with a financial kernel that maps raw accounting numbers into a broader set of ratios. 相似文献

This paper provides an empirical analysis of the factors explaining U.S. countervail action. Factors that indicate changes in the political economic environment are incorporated into a logit model to explain the propensity to initiate a countervail suit. These factors, augmented by variables representing foreign subsidy specificity, are used in a logit model to explain the propensity to levy a countervail duty, once a suit is initiated. Evidence indicates that factors that would lead to political lobbying are significant in the initiation of a countervail suit. However, these variables are not significant in explaining the propensity to actually levy a duty; rather, the analysis finds that subsidy specificity criteria are the significant variables. 相似文献

This paper provides a content analysis of portrayals of children's participation in household tasks in national television advertisements within the U.S.A. The analysis indicates that children are rarely shown working in the home, even when they could help. Furthermore, parents are shown routinely performing tasks children could have done for themselves. The resulting stereotypes are clearly drawn: children are shown to be non-productive and parents are portrayed as servants. Such portrayals may be counter-productive in the context of growing time pressures in the household and the potential benefits that families might realize by working together towards common goals. 相似文献

In the wake of Wal‐Mart and other mass merchandisers’ entry into food retailing, the nature of competition in the industry has changed radically. Using longitudinal data on workers and firms to construct measures of compensation and churning for traditional food retailers, this paper examines how these measures change in response to mass merchandiser entry. While there is considerable heterogeneity across retail food establishments, human resource practices are persistent even in the face of new external competition. 相似文献
