Martin F. J. Prachowny 《Journal of Labor Research》1981,2(1):15-24
The question addressed in this paper is: Do social benefits from wage indexation coincide with private incentives to incorporate COLA clauses in union contracts? In general, market forces provide an “approximately correct” solution so that legislative remedies are not required. Based on the work of Gray and Fischer, full indexation is beneficial when the economy is subjected to stochastic nominal shocks, but only partial indexation is optimal when real disturbances dominate. If unions and management of firms are risk-averse they both have an incentive to adopt full indexation when monetary uncertainty exists. On the other hand, when the economy faces real shocks, union negotiators oppose indexation if the demand for labor is elastic, but insist on full indexation if demand is inelastic. Managers of firms prefer nominal wage contracts in either case. This suggests that both parties will agree to omit COLA clauses in the first case, but are likely to compromise with partial indexation in the second case. A role for government intervention is indicated only to the extent that bargaining strength may dictate a degree of indexation that deviates from the social optimum. The analysis is extended briefly to other assumptions about the utility function of the two parties at the bargaining table. 相似文献

Management Information Systems and Corporate Planning 总被引:2,自引:0,他引:2
John F. Green 《Long Range Planning》1970,2(4):74-78
If we accept the correlation between MIS and computer based systems then the corporate planner has to consider the impact on his own company of a major new function. In so far as computers and the associated highly paid staff are concerned, the planner is certainly threatened with a major cost growth area that develops a momentum of its own. He may need all his energy to contain this growth in highly expensive resources to a scale that matches the company's overall operations. On the other hand an emphasis on management information and redesigned systems may lead to radical redesign and improvement in profitability of a company's operations. These two aspects are different sides of the same coin and in the future the corporate planner will play a dominant part in determining whether a company enjoys the benefits as well as incurs the costs of a sophisticated MIS. 相似文献

The 1970 census included numerous procedural innovations, of which the most important was the use of mail-out/mail-back techniques. A statewide survey of Wisconsin households (conducted in May and June, 1970) included questions designed to elicit information on the degree of cooperation rendered, ease of comprehension of the form, possible objectionable items on the census, whether or not contacts were made by enumerators, and respondent judgments of the adequacy of enumerators’ performance. The results indicate that Wisconsin respondents tended to comply with census procedures, that they found very little difficulty in filling out the mailed forms, and that they regarded the census enumerators as doing a “good job” in most cases. 相似文献

Personal, health, academic, and environmental predictors of stress for residence hall students 总被引:4,自引:0,他引:4
Dusselier L Dunn B Wang Y Shelley MC Whalen DF 《Journal of American college health : J of ACH》2005,54(1):15-24
The authors studied contributors to stress among undergraduate residence hall students at a midwestern, land grant university using a 76-item survey consisting of personal, health, academic, and environmental questions and 1 qualitative question asking what thing stressed them the most. Of 964 students selected at random, 462 (48%) responded to the survey. The authors weighted data to reflect the overall university-wide undergraduate population (55% men, 12% minority or international, and 25% freshmen). Women and US citizens experienced greater stress than did men and non-US citizens, respectively. Frequency of experiencing chronic illness, depression, anxiety disorder, seasonal affective disorder, mononucleosis, and sleep difficulties were significant stress predictors. Although alcohol use was a positive predictor, drug use was a negative predictor of stress. Both a conflict and a satisfactory relationship with a roommate, as well as a conflict with a faculty or staff member, were also significant predictors of stress. 相似文献

To participate or not to participate: that is the question 总被引:1,自引:0,他引:1
Borden LM Perkins DF Villarruel FA Stone MR 《New directions for youth development》2005,(105):33-49, 10
Do I wish to participate or not to participate in this program? That is the question that young people ask themselves when considering a new opportunity. What can be done to increase the likelihood that they will choose to participate in out-of-school-time (OST) programs? This chapter describes a qualitative study that examined reasons for participating or not participating in OST programs. Some common reasons emerged, but the study also revealed differences among youth from different ethnic groups. It is clear that those who design and conduct programs must understand the processes through which diverse adolescents initiate their participation in programs and either persist or drop out. Given the apparent benefits of active participation in youth programs, it is important to remove barriers and increase access and, equally important, design programs that are of interest to youth in the contexts in which they live. 相似文献

Using the data from the AIDS Link to Intravenous Experiences cohort study as an example, an informative censoring model was
used to characterize the repeated hospitalization process of a group of patients. Under the informative censoring assumption,
the estimators of the baseline rate function and the regression parameters were shown to be related to a latent variable.
Hence, it becomes impractical to directly estimate the unknown quantities in the moments of the estimators for the bandwidth
selection of a smoothing estimator and the construction of confidence intervals, which are respectively based on the asymptotic
mean squared errors and the asymptotic distributions of the estimators. To overcome these difficulties, we develop a random
weighted bootstrap procedure to select appropriate bandwidths and to construct approximated confidence intervals. One can
see that our method is simple and faster to implement from a practical point of view, and is at least as accurate as other
bootstrap methods. In this article, it is shown that the proposed method is useful through the performance of a Monte Carlo
simulation. An application of our procedure is also illustrated by a recurrent event sample of intravenous drug users for
inpatient cares over time. 相似文献

A model is developed to use marital history data from the U.S. Current Population Survey and mortality statistics from the federal registration system to estimate color differences in (a) the risk of widowhood among women in the working ages and (b) the cumulative duration of widowhood. Color differentials in mortality among married males are thereby translated into person-years of dependent survivorship among women, in anticipation of our later estimating average and cumulative lifetime income losses for the survivors. Initial results of this model, dealing with the demographic aspects of survivorship, are presented. 相似文献

C. F. Midelfort 《Journal of marital and family therapy》1982,8(2):1-11
Editor's Note. Occasionally, the Journal of Marital and Family Therapy will publish papers of major historical significance to the field of family therapy which, though written long before their appearance in the Journal, have remained unpublished and received little public circulation or attention. Such papers are those which, in the view of the Editor, would have been certain “classics” in the literature of family therapy had they been published when they were written, and which, despite their overdue appearance, are of significant enduring value. The first of these papers, by Dr. C. F Midelfort, appears here. Though essentially isolated from the family therapy movement that was soon to follow, Dr. Midelfort, in fact, published the first book on family therapy. The present article grows out of what was probably the first paper on family therapy ever presented at a psychiatric convention in the United States. In this paper, originally written almost exactly thirty years ago, Dr. Midelfort articulately presents a creative interweaving of an appreciation of the psychodynamics of family relationships with an ego-oriented family approach to severe psychiatric disturbance in one family member. It is an innovative presage of the flexible use of the principles of family dynamics, social psychiatry and biological psychiatry that has been “discovered” only very recently in family therapy with schizophrenics. The paper is introduced by Dr. John E. Bell, to whom the Journal is grateful for bringing it to light. 相似文献

Recent work on extended optimality criteria for robust designs is applied to response surface problems. Methods of calculation are described and the criteria illustrated with several examples. The extended criteria discriminate among designs equivalent by other criteria. 相似文献
