The Colorado Occupant Protection Project (COPP) intervention provided police with brief instruction concerning the importance of citations for drivers' failure to use child safety seats and special coupons to accompany citations. Coupons were exchangeable by drivers for a safety seat and brief training in its use, plus a waiver of the $50 citation fine. Over 4.5 years of archival records were employed, using an ABA design and a comparison community to evaluate the program. Few tickets were issued for nonuse of safety seats during the 3-year baseline in either community. Citations for nonuse of safety seats increased to over 50 per month during the intervention period at the test site, whereas rates remained essentially zero at the comparison site. After the COPP intervention was removed at the intervention site, citation rates for nonuse of safety seats decreased to about 15 per month. Differences between intervention conditions and settings were statistically significant. During the intervention, officers were 44 times more likely to write citations than were controls. Results suggested that a behavioral program can increase police citation writing for child protection purposes.  相似文献

We assessed whether written task analyses would serve as textual prompts for performing functional tasks by persons with mild disabilities. Several variables that could influence the effectiveness of textual prompts to promote stimulus control were examined across four groups. A consistent finding was that written specific task analyses combined with end-of-trial performance feedback were effective for promoting the acquisition and generalization of several tasks. Performance transferred immediately to natural discriminative stimuli when the written task analyses and feedback were withdrawn for most tasks and participants. For 2 participants, transfer of stimulus control was accomplished by prompt fading, using individualized written task analyses either with or without performance feedback (Group 1). When feedback was not provided, the effectiveness of written specific task analyses was inconsistent across groups. In contrast to the controlling effects of written specific task analyses, written generic task analyses, which specified only major task outcomes, when combined with performance feedback (Group 1) did not control responding. Overall, this research demonstrated the effectiveness of written specific task analyses and performance feedback to promote stimulus control for persons with mild disabilities.  相似文献

The effects of altering light pattern sequences on driver compliance at a busy, urban intersection were explored. The baseline light timing sequences resulted in only 46.8% of drivers stopping at the yellow or red lights. Using an A-B-C design, we altered light pattern sequences that increased the probability of drivers stopping at the signals to 88.8% and 98.8%. These findings indicate that traffic light contingencies have potent effects in influencing driver behaviors at busy intersections. Following completion of the study, the traffic engineer approved the permanence of the light timing pattern that increased traffic rule compliance. Accident data collected before and after the light timing changes indicated a reduction in automobile accidents.  相似文献

Community participation is essential for community development and enhancing quality of life. Several studies have focused on the relationship between sense of community (SOC) and community participation in organizational settings. Guided by the community experiences framework, this study aims to examine how a SOC improves community participation in Chinese residential communities. Moreover, the study aims to assess the mediating role of SOC responsibility (SOC-R) and prosocial tendencies in that relationship. A sample of 433 residents completed questionnaires regarding their SOC, sense of community responsibility, prosocial tendencies, and community participation. Using a linear regression model, we found that a SOC can positively predict the level of community participation. Mediation effect analysis revealed that a SOC-R mediated the relationship between SOC and community participation. In addition, prosocial tendencies mediated the association between the SOC and community participation. Using multiple mediation analysis, we found that SOC-R and prosocial tendencies mediated the link between a SOC and community participation in a sequential manner. The findings of this study complement existing research by uncovering the mechanism underlying the relationship between a SOC and community participation.  相似文献

We evaluated strategies to increase behaviors associated with courteous provision of service by 3 staff members of a human service agency. Training included written instructions, practice, and performance feedback. A lottery procedure was introduced to maintain courteous service after training. The results of a multiple baseline design across the 3 participants showed marked increases in courteous behaviors following training. These effects were maintained at 3-, 5-, and 8-month follow-ups. Consumers' satisfaction with service also increased. These findings suggest that simple training and reinforcement procedures can enhance courtesy afforded those who receive service from public and nonprofit organizations.  相似文献

The literature is reviewed to define a sense of community in the workplace and to identify factors that may foster it. A model is developed and estimated with survey data from a culturally diverse sample of men and women performing lower-level jobs at a medium-sized manufacturing firm. Results of regression analyses are reported that correct for sample selection bias resulting from the lower response rates of minority workers. Findings suggest that well-designed jobs and supportive workplace relationships and policies are important in explaining workers' sense of community, defined as workers' perceptions of mutual commitment between employee and employer. Informal sources of support play a larger role in explaining men's sense of community, while formal sources of support are more important in explaining women's sense of community. Findings further suggest that African American workers, especially women, have a difficult time experiencing a sense of community at work. The authors thank the employees of Fel-Pro for their participation in this study and Melissa Roderick, Michael Sosin, and anonymous reviewers for their thoughtful comments. This research was funded by the Fel-Pro/Mecklenberger Foundation and the Lois and Samuel Silberman Fund.  相似文献

A comprehensive model of intrapersonal empowerment in the workplace posits that empowerment mediates the relationship between the social structural context and behavioral outcomes. The social structural context is operationalized as perceptions of role ambiguity, sociopolitical support, access to strategic information and resources, and work unit culture, whereas behavioral outcomes are operationalized as innovativeness and effectiveness. The model is examined on a sample of 324 middle managers from different units of a Fortune 50 organization. Survey data are examined using a series of regression analyses to assess the mediating effect of intrapersonal. Results suggest that intrapersonal empowerment mediates the relationship between some elements of workplace social structure and innovativeness, but not effectiveness. Although not a mediating mechanism for effectiveness, intrapersonal empowerment is nonetheless directly related to effectiveness (as assessed by the respondent's subordinates). Implications of the results are discussed as are study limitations and directions for future research. This paper is based on the author's dissertation, presented in partial fulfillment of the requirement for the doctoral degree at the University of Michigan. I am grateful to my dissertation committee which included Robert E. Quinn (chair), Susan Ashford, Richard Bagozzi, Karl Weick, and Marc Zimmerman for their thoughtful guidance. Thanks is also extended to Neil Sendelbach for his help in facilitating data collection. The University of Michigan and the University of Southern California both provided financial support for this research. This paper was prepared while the author was a Zumberge Fellow at the University of Southern California.  相似文献

The present study employed reinforcement-based methods to induce existing members to recruit new members to join a chamber of commerce. Three interventions took place during June and July of 3 successive years. The investigators trained chamber leaders to use reinforcement methods (e.g., contingent tokens) to reinforce recruitment and dues collections. All three interventions produced substantial increases in their targets.  相似文献

This paper offers an analysis of the notion the quest for identity. The discussion emphasizes the importance of communal belonging, but rejects the view that one ought to belong to the community one was born to. It suggests that the quest for identity may lead individuals to follow many avenues: while some individuals might affirm their inherent affiliations and traditions, others may remain within their community of origin and strive to change its ways, or chose to leave their social group and opt for membership in a new one. This analysis suggests that choice, characteristic of the liberal conception of the person, and rootedness, characteristic of the communitarian conception of the person, both play an important role in the formation of personal identity.  相似文献

In responding to and examining Mary Anne Raywid's (1989) adoption of community building as an aim for schools, I survey a number of types of communities, including recreational, intentional and language communities. In considering all these communities, I try to show both the power of communities in our personal lives and some idea of why we might be of two minds about promoting community as an ideal in the modern world and in schools in particular.  相似文献
