Paths to community empowerment: Organizing at home   总被引:1,自引:0,他引:1  
This study examines how low-income minority communities build on their strengths to improve material conditions and how these actions lead to further empowerment at the individual and group level, and increase engagement with civic life. Based on earlier qualitative research, low-income limited equity housing co-ops were chosen as research. Using quantitative questionnaire data, a path model was tested in which variables were organized into four levels.Level One: Attributes of the person and the context were conceptualized asexogenous variables leading to activities first at the co-op level.Level Two:co-op activities were thought to affect living conditions in the building and evaluations of co-op ownership, which comprisedLevel Three,quality of life in the building. All preceding levels were thought to influenceempowerment, as measured atLevel Four through an attitudinal measure of empowerment, and reported participation in civic activities in the broader community. The model, which emphasizes the collective and material nature of empowerment in addition to the psychological, seems justified by the data. It is especially significant that the aggregate measure of perceived participation of others predicted building quality, and that the aggregate measure of building quality went on to influence empowerment and voting behavior. Personal participation in building activities also proved a good predictor of empowerment, indicating that empowerment operates at both the individual and the group level. Furthermore, increased empowerment at the level of attitude did influence civic activities, in conjunction with personal characteristics and perceived neighborhood qualities. (Tests of causality in the opposite direction were not significant.) Our findings confirm the importance of all three components of empowerment, as articulated by Zimmerman and his colleagues (1992), that is, empowerment at the psychological, interactional, and behavioral level. It extends the conceptualization by introducing the group level of analysis. We thank the Robert F. Wagner Sr. Center for Urban Public Policy at the City University of New York Graduate School and University Center and the Fund for the City of New York for early support and the Edna McConnell Clark Foundation for current support. We acknowledge the invaluable participation in the original project of Heléne Clark, Eric Glunt, Bill Roane, and April Tyler. We also thank the anonymous reviewers and the editor for their helpful and extremely thorough comments and suggestions.  相似文献

Used a sample of 207 single-parent families residing in 104 small, Midwestern communities to test hypotheses regarding the link between community context and adolescent conduct problems and psychological distress. For boys, community disadvantage had a direct affect on psychological distress, while it indirectly boosted the probability of conduct problems by disrupting parenting and increasing affiliation with deviant peers. Community disadvantage was unrelated to the deviant behavior or emotional well-being of girls. Proportion of single-parent households in the community had a direct effect on girls' conduct problems. It also contributed indirectly to girls' conduct problems by increasing the probability of involvement with deviant peers. Possible explanations for these gender differences are provided. An earlier version of this paper was presented at the annual meeting of the American Society of Criminology, Miami, November 1994. Work on this project was supported by the National Institute of Mental Health (MH48165) and the National Institute of Child Health and Human Development (HD27724).

An instructional procedure composed of a graded sequence of prompts and token reinforcement was used to train a complex chain of behaviors which included sorting, washing, and drying clothes. A multiple probe design with sequential instruction across seven major components of the laundering routine was used to demonstrate experimental control. Students were taught to launder clothing using machines located in their school and generalization was assessed later on machines located in the public laundromat. A comparison of students' laundry skills with those of normal peers indicated similar levels of proficiency. Follow-up probes demonstrated maintenance of laundry skills over a 10-month period.  相似文献

To increase the return rate of questionnaires mailed to clergy and physicians concerning their mental-health practices, different prompts were used after the questionnaire was received during four mail-outs to four randomly drawn samples of clergy and physicians. For each mail-out, the sample was divided into experimental (received prompt) and comparison (no prompt) groups, and one type of prompt or combination was used. Non-returnees of the questionnaire in the experimental group received either: (a) a single telephone call, (b) a memo, (c) a package (personal letter and new questionnaire) or package plus a telephone call, or (d) a double call. Comparison physicians and clergy were mailed only the original questionnaire. Relative to their respective comparison group's return rate, which averaged 22% across the four mail-outs (range 18% to 24%), the single call and package alone about doubled the overall return rate, the package and call increased the return rate about two-and-a-half fold, and the double call almost tripled the return rate. The memo was ineffective. A cost-effectiveness analysis indicated that the double-call procedure was less expensive than the single call, and much less expensive than the package alone or package with a call in securing returns. An analysis of the pattern of returns showed clearly that when prompts were not delivered (comparison groups), very few returns were received after about seven days from the initial mail-out. Most returns from prompts (experimental groups) were received by several days after the prompt. The results were seen as salient to the problem of reducing selection or volunteer bias in questionnaire studies and subsequent research demonstrating the effectiveness of telephone calls made about a week after distribution of surveys in securing high return rates was discussed.  相似文献

Organizations are increasingly faced with the need to "reinvent" themselves as they adapt to a changing society. In this article, the university is examined as one such organization. Faced with enormous pressures to educate an increasingly diverse group of students, equip them with skills for the global marketplace, and prepare them to be responsible citizens, the university must become a more responsive institution that can respond effectively to these challenges. Various perspectives on how the university can become a learning organization are discussed. Central to the discussion is the need to change the university culture in ways that encourage and nurture more interdisciplinary programs and problem-focused teams that address the needs of communities. It is suggested that culture change is also necessary to encourage the development of new types of learning environments that nurture the spirit and the mind. Future business organizations are then compared with the university. A key issue that needs to be considered is how universities can better prepare students for the work settings of tomorrow. It is suggested that such preparation requires environments that help students adapt to change and encourage them to become lifelong learners.  相似文献

Health in Housing initiated a behavioral program of education and skills training for children and adults in a community of 30,000 persons living in substandard conditions in Tegucigalpa, Honduras. To measure achievement in the long-range project, 21 families of Flor del Campo participated in a preliminary three-part survey of their (a) health, (b) housing and the environment, and (c) family history. Doctors, designers, and educators worked with Honduran personnel in the first survey. Following functional analyses of the home and surrounding environment and the physical status of the individuals living there, procedures provide the family with treatment and training for home and environment improvement. Graphic, verbal, and numerical data, incorporated into a master computerized system, record events of each family member: training programs experienced, health care delivery courses taken, medical treatments, growth of children, literacy changes, educational courses completed, kinds and amounts of foods eaten, household and building materials purchased. Ongoing functional analysis and a long-range evaluation are made of the progress of each participating individual in a family. Teams revisit each house to observe and record any changes in the physical and environmental facility and the health and life-styles, and to report any indications of new health problems or recurrences.  相似文献

Considers the potential benefits and costs of an alternative career model for community researchers, one in which professionals specialize in the community where they live. By virtue of their local familiarity, resident researchers can make more informed judgments about research problems and methods. They can employ longitudinal designs to assess change and be available to assist in interpretation and implementation of research. Potential costs include the possibility of provincialism, unintended researcher effects, ethical dilemmas, the need to cultivate community relations, and role conflicts. Interdisciplinary training programs and research field stations can contribute to the development of the resident researcher role. Researchers in the community can help generate grass roots support for social science research. We acknowledge Louise Shedd Barker's helpful comments and suggestions on an earlier version of this article.  相似文献

This study evaluated the efficacy of a personalized system of instruction to teach checking account skills to persons with mild disabilities. Using a self-paced manual, 8 participants in two groups were taught to write checks, complete deposit slips, and reconcile monthly bank statements. Four participants were assessed for generalization from the classroom to community sites and demonstrated nearly perfect performance. A multiple probe design showed that acquisition occurred sequentially for each skill only after training using the self-paced manual. Follow-up sessions demonstrated that participants maintained the checking account skills. The results provide evidence of the effectiveness and adaptability of a personalized system of instruction for teaching complex monetary skills to persons with mild disabilities.  相似文献

Sexually transmitted diseases are a serious threat to the public health. Indeed, when an individual seeks medical treatment for a sexually transmitted disease, health authorities frequently attempt to identify, procure, and treat that individual's sexual contact(s). We conducted a comparative analysis of three alternative approaches to tracing the sexual partners of individuals diagnosed as having a sexually transmitted disease. The first approach involved counseling individuals (n = 27) infected with either gonorrhea or nongonococcal urethritis and exhorting them to procure their sexual partners for treatment. In addition to counseling, the second and third approaches involved distributing “occasion cards” for patients to use when informing sexual contacts of the need for treatment. Moreover, in the second approach, the counselor (a nurse or physician) informed infected patients (n = 19) that they and their partners could waive the $3 clinic fee contingent upon the partners seeking treatment within 1 week. In the third approach, the counselor asked infected persons (n = 19) to accept a follow-up telephone contact if their sexual partners failed to seek treatment within 1 week. The third approach was most effective. Ninety percent of the partners identified through this approach sought treatment, versus only about 60% of the partners in the other two conditions. The third approach was also the least expensive, costing about $2.95 to procure each partner for treatment.  相似文献

We replicated a study by Van Houten, Nau, and Marini (1980) that had revealed reductions in vehicle speeding following the posting of percentages of drivers not speeding on a sign at roadside. Our subjects were drivers entering a residential area where the speed limit changed from 90 km/hr (55.9 mph) to 60 km/hr (37.3 mph). A total of 4,409 vehicle speeds were taken from two observation sessions per day for 20 consecutive weekdays. The intervention consisted of a single posting condition, in which a hypothetical daily percentage of drivers not speeding was posted on a feedback sign, followed by a double posting condition, in which a sign posting a best result was erected beyond the feedback sign. Results revealed a significant speed reduction from an average of 69.0 km/hr (42.9 mph) during baseline to 63.4 km/hr (39.4 mph) during single posting. Average speed during double posting was 62.9 km/hr (39.1 mph). The percentage of drivers exceeding 70 km/hr (43.5 mph) dropped from 41.0 during baseline to 20.5 during single posting. The significant speed reductions add to the generality of findings of similar studies in Canada and Israel and offer possible explanations for the failure of feedback posting to reduce speed in the U.S.  相似文献
