This study examines the relationship between employed wives' preferences for household production time, employment time, leisure, and their actual time use. A random sample of 235 employed, married women estimate their time use on an average weekday and weekend day in 13 activities and indicate their preferences for time in those activities. Hierarchical multiple regression procedures are used to examine the relationships between actual and preferred time use. Weekday employment time is not related to preferences for more or less time in household production but wives allocating more time to employment want to spend less time at that employment and more time in leisure. Weekend employment time is related to preferences for more time in leisure, child care, and other household work. Time spent performing household work is not related to preferences for more or less time in any activity except the desire for more leisure time on weekends.Ann Renigar Hiatt is Assistant Professor in the Department of Human Services, College of Education and Allied Professions at the University of North Carolina at Charlotte, Charlotte, NC 28223. Her research interests include employed women's time allocation, time pressures, and use of time management strategies. She received her Ph.D. from the University of North Carolina at Greensboro.Deborah D. Godwin is Associate Professor in the Department of Housing and Consumer Economics at the University of Georgia, Athens, GA 30602. Her research has focused on husbands' and wives' time allocation to household production, the effects of women's employment on family economic functioning, and family financial management. She received her Ph.D. from the University of North Carolina at Greensbore. 相似文献

The number of people accessing the Internet for sexual purposes (cybersex) has increased dramatically over the last 10 years. However, little research has been conducted to determine how frequently clients present for treatment with cybersex‐related issues. One hundred sixty‐four clinical members of the American Association for Marriage and Family Therapy participated in the current study, which was conducted to identify the impacts of cybersex on MFTs’ practices. Most respondents report seeing clients with cybersex‐related issues, with client numbers increasing over the past 2 years. Although most respondents felt prepared to diagnose and treat adults with cybersex problems, half felt unprepared to diagnose and treat children. Lastly, most respondents reported that their required college courses were not helpful in preparing them to diagnose and treat cybersex‐related problems. The implications of study findings are discussed. 相似文献

The author of this article argues that inflation is a neglected area in corporate planning despite the events of 1974/1975. The planning problem which companies face because of inflation is defined, while acknowledging that it is difficult to solve. Recent experience has shown that inflation has a direct impact on every major area of business. Thus it is essential that there is a meaningful attempt to handle these problems in planning. The author discusses his approach to grasping this nettle. 相似文献

In the last 10 years much has been written about the increasing environmental uncertainty firms and other organizations have to cope with. This uncertainty made it much more difficult to plan, since unexpected events often made them obsolete.Flexibility is frequently considered as a way to ‘solve’ the problem of environmental turbulence.In this article, based upon theoretical and empirical research, the author explores the concept of flexibility, puts forward some of his research findings, and advances some implications on how to increase strategic flexibility. 相似文献

Summary. We consider the Bayesian analysis of human movement data, where the subjects perform various reaching tasks. A set of markers is placed on each subject and a system of cameras records the three-dimensional Cartesian co-ordinates of the markers during the reaching movement. It is of interest to describe the mean and variability of the curves that are traced by the markers during one reaching movement, and to identify any differences due to covariates. We propose a methodology based on a hierarchical Bayesian model for the curves. An important part of the method is to obtain identifiable features of the movement so that different curves can be compared after temporal warping. We consider four landmarks and a set of equally spaced pseudolandmarks are located in between. We demonstrate that the algorithm works well in locating the landmarks, and shape analysis techniques are used to describe the posterior distribution of the mean curve. A feature of this type of data is that some parts of the movement data may be missing—the Bayesian methodology is easily adapted to cope with this situation. 相似文献

This paper discusses significant counter-transference issues and presents a conceptual framework for ordering the strategies in treating the mother in the incest family. The development of empathy is suggested as the primary engagement tool, and obstacles to its development are analyzed.The major theoretical construct that is employed in formulating the treatment approach is that of the traumagenic dynamics model presented by Finkelhor and Browne (1985). The manner in which this framework can be employed in assessment and prioritizing treatment goals is outlined. Specific approaches for the beginning phase of work with the mother are then described. 相似文献

Influence diagnostics in the capital asset pricing model under elliptical distributions 总被引:1,自引:0,他引:1
In this paper we consider the Capital Asset Pricing Model under Elliptical (symmetric) Distributions. This class of distributions, which contains the normal distribution, t, contaminated normal and power exponential, among others, offers a more flexible framework for modelling asset prices or returns. In order to analyze the sensibility to possible outliers and/or atypical returns of the maximum likelihood estimators, the local influence method was implemented. The results are illustrated by using a set of shares from companies who trade in the Chilean Stock Market. Our main conclusion is that symmetric distributions having heavier tails than those of the normal distribution, especially the t distribution with small degrees of freedom, show a better fit and allow the reduction of the influence of atypical returns in the maximum likelihood estimators. 相似文献

The authors propose a semiparametric approach to modeling and forecasting age‐specific mortality in the United States. Their method is based on an extension of a class of semiparametric models to time series. It combines information from several time series and estimates the predictive distribution conditional on past data. The conditional expectation, which is the most commonly used predictor in practice, is the first moment of this distribution. The authors compare their method to that of Lee and Carter. 相似文献
