Three-dimensional contingency tables are analyzed, with one variable (e.g., sex) as a factor, and with a natural relation between the other variables (e.g. left and right eye vision). Models of special interest, like symmetry and proportional symmetry between the related variables, and homogeneity across the factor levels, are investigated. Maximum likelihood estimators of parameters and partitions of chi-square goodness-of-fit statistics are explicitly presented; the independence of certain models is noted, and an example is discussed.  相似文献

A 2×2×2 factorial design was employed to examine the influence of instructed leadership style, sex of leader, and sex of followers on leader behavior, subordinate satisfaction, and productivity in a simple task. In general, male and female leaders were equally able and equally willing to display autocratic and democratic leadership styles if so instructed. Similarly, leader sex did not have a significant influence on subordinate satisfaction or productivity either by itself or in interaction with leadership style or follower sex.  相似文献

The importance of values in clinical settings is a topic of increasing discussion in the medical literature, but the nature of values and the process of interpreting them have received little attention. The hospital chaplain or religious professional is an underused resource in addressing values issues. This paper summarizes the current models of the hospital chaplaincy in historical context, and then develops a new model drawn from the disciplines of pastoral care and clinical medical ethics in order to address problems involving values in clinical settings. The model construes the chaplain as values interpreter who provides both consultation and liaison functions in clinical situations. We present a clinical case to illustrate the role of the values interpreter. We conclude that the religious professional can make an important contribution to both clinical decision making and medical education through such a model.The authors thank Don S.

This study uses a model of consciousness derived from LSD-assisted psychotherapy to illumine an enigmatic set of painful experiences that occur on the mystic's path known in Western circles as the dark night. It argues that the dark night experiences described in John of the Cross's classic workDark Night of the Soul can be conceptualized in terms of Stanislav Grofs category of perinatal experience. The discussion examines the implications of this reconceptualization in three areas: (1) our understanding and evaluation of mysticism, (2) assessing LSD's potential for fostering genuine spirituality, and (3) reassessing the ancient claim that the capacity to experience transcendental states of being is innate.  相似文献

Forty-one Protestant ministers completed measures of stress-related symptoms, family of origin contact, church governing body density, history of pastor-parish conflict in the church, and a measure of Bowen's (1959b/1985) concept of emotional triangles. A denominational executive provided ratings of each church's history of pastor-parish conflict. Path analysis using multiple regression showed support for a model in which governing body density and history of conflict predicted emotional triangles, and emotional triangles predicted stress symptoms. Contact with the pastor's family of origin moderated the relationship between emotional triangles and stress symptoms. Results suggest that the organizational and family ecology of the ministerial role can be important in understanding occupational stress among ministers.  相似文献

Maximizing the potential of worksites for smoking intervention remains elusive. We hypothesized that long-term effectiveness of group intervention would be enhanced when offered within an "enriched milieu" (full program) compared with relative isolation (group only). The data failed to support the hypothesis. Although sustained abstinence rates were higher at full-program sites (50%) than at group-only sites (44%), the difference did not achieve statistical significance. Initial (35% vs. 47%) and 12-month (18% vs. 22%) quit rates at full-program and group-only sites also failed to demonstrate the "benefit" of the "enriched milieu."  相似文献

It has been recently shown that in the early stages of erection, the human penis undergoes a substantial length change that is not detected using circumferential measurement devices. The present report introduces a relatively simple device that can assess changes in both length and circumference. The device promises to provide a low-cost alternative to the precision and sensitivity associated with plethysmography.  相似文献
