Unionized workers at a factory were asked to rate a variety of reasons which would justify the use of sabotage in an organization, as well as the justifiability of four general methods of sabotage (slowdowns, destructiveness, dishonesty, and causing chaos). Results showed that as compared to those who didn't accept a wide variety of reasons for sabotage, those who accepted a variety of reasons would more readily justify all forms of sabotage except dishonesty. The data is discussed in terms of the reasons for the lack of justification that dishonesty receives, as well as future directions for the study of sabotage.  相似文献

Increasing numbers of Spanish-heritage immigrant families in the United States are beginning to seek therapy for family conflicts related to their adapation to the new country/culture. This paper focuses on the difficulties experienced by these families and presents issues specific to therapy with them. Effective therapy with these families requires that therapists focus on clarification of the differential adaptation rates of family members and facilitate a resolution of the family's transitional conflicts(s). Six cases involving such families are presented.David A. Baptiste, Jr., PhD, is a Psychologist and Marital and Family therapist in the counseling center at New Mexico State University and in private practice, Las Cruce, NM.Revision of a paper presented to the International Round Table for the Advancement of Counseling, Annual Conference, Utrech, The Netherlands, July, 1985. The author expresses appreciation to Judith Landau-Stanton for her helpful review of an earlier draft of this paper.  相似文献

The present study was conducted to examine the hypothesis that compliant chronically ill patients, typically described as adjusted, reinforce more positive social environments using behavioral controls than noncompliant patients, typically described as maladjusted. Specifically, it is hypothesized that diet-compliant chronic hemodialysis patients emit significnatly more active involvement-in-treatment behaviors and more social behaviors than diet-noncompliant chronic hemodialysis patients. Subjects, who ranged in age from 30 to 77 years, were outpatients at a kidney center. Behavioral observations were conducted to assess the occurrence or frequency of (1) four involvement-in-treatment behaviors that are routinely taught to all patients and (2) two social behaviors, which were patient verbalizations and smiles. The results showed that compliant patients emitted significantly more involvement-in-treatment behaviors and smiles than noncompliant patients. Results support the proposed control framework that compliant, in contrast to non-compliant, chronically ill patients have recourse through positive behavioral controls when adjusting to the stresses of illness. It was proposed that through these controls, compliant patients reinforce positive environments rather than simply respond to life circumstances as given.  相似文献

Several theories have been presented that predict differences between women and men in attitudes toward the environment due to differences in sex roles. Research on which these theories can be tested has tended to examine general environmental concern, and the results have generally been weak and inconclusive. Using an approach suggested in the literature, this study examines sex differences in concern and knowledge, using multi-item scales for each, about one environmental issue — acid rain. The results contradict the theories being tested, however: if there is a sex difference, men are found to be more concerned and knowledgeable about the environmental problem.  相似文献

A total of 45 subjects in three age groups (younger, middle-age, older) were trained to word process on microcomputers using a commercial training program and an experimenter-designed test and evaluation protocol. Although all of the subjects mastered the essentials of word processing, the older group took significantly longer to complete the training and evaluation procedures and performed more poorly on a review examination that tested their knowledge of the word-processing commands and techniques. The results are discussed in relation to requirements for trainer assistance, motivational factors, and the need to design training protocols that meet the needs of older adults.  相似文献

I hypothesized that feelings of strain experienced by an adult daughter are likely to interfere with the nature of her relationship with her aging mother and to have a potentially deleterious effect on the mother. To test this proposition, I devised a study that examined the impact of two brief interventions on 37 middle-aged women and 24 of their elderly mothers: (a) a cognitive-behavioral presentation designed to reduce the daughter's unrealistic feelings of responsibility and (b) a supportive-educational presentation designed to increase the daughter's awareness of her mother's needs. I found that the first procedure was more effective than the second in reducing the daughter's burden, improving the mother-daughter relationship, and decreasing the loneliness experienced by the elderly mother.  相似文献

The authors describe a career counseling strategy based on specific psychosocial characteristics of battered women. The approach is developmental in nature, focusing on the client's self-concept. A group format based on a pilot intervention is proposed to assist battered women in developing appropriate life and career decision-making skills.  相似文献
