In this paper a method for the construction of a class of row-column designs with good statistical properties and high efficiency is presented. The class of designs produced is shown to exhibit balance, orthogonality and adjusted orthogonality. The efficiencies of these designs are investigated in detail, and they are shown to be very high, and possibly maximal in some cases. 相似文献

This study examined the impact of information subsidies on media coverage during a crisis. Using the July 2006 Israel–Lebanon conflict as a backdrop, this research reviewed access that U.S. military public affairs officers provided the media and analyzed subsequent coverage for the presence of the military's message. Coverage was more neutral to positive than negative. Items containing organizational messages were more positive; those quoting practitioner-facilitated sources introduced organizational messages into coverage and generated more positive coverage. Access to information subsidies had a positive impact on coverage and aided in the successful transfer of attribute salience from practitioners to the media. 相似文献

Eighty-two mothers and 46 fathers of emotionally disturbed youth in a day treatment program completed the Family Assessment Device (FAD) at time of intake. Interviews with therapists enabled classification of families into three groups: those whose client (the youth) had been sexually abused, those where sexual abuse was suspected but not confirmed, and those without a sexual abuse history. All cases of abuse were non-incestuous. Comparisons of the confirmed abuse and non-abuse groups were made, using three types of analyses. ANOVA of parental responses to the FAD by group yielded significance for mothers but not for fathers, with mothers of abused children reporting more family dysfunction in problem-solving and roles than mothers of non-abused children. Second, significant differences between parents according to group were found in the abused sample in problem-solving, communication, and general functioning, but not in the non-abused sample; mothers reported significantly greater pathology in their families than did fathers. Third, comparison of differences between mothers and their children within families yielded a greater number of differences in the non-abused group. Significance was obtained in affective responsivity and behavior control in both samples. Additionally, however, significant differences in communication and roles were obtained in the non-abused group. Caution in differentiating between incestuous and non-incestuous families is suggested. Implications of this research for family interventions, especially with regard to mother/child perceptual congruence, are discussed. 相似文献

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
