Shoplifting and employee theft constitute a major problem for retailers. Previous research has described techniques for effectively reducing either type of theft but has not addressed the problem of thefts of unspecified origin. In a grocery store we evaluated the effect of identifying for employees frequently stolen products from three groups of items and graphing, twice weekly in the lunchroom, losses for the separate groups. After the products were identified and losses graphed, thefts from the three groups dropped from eight per day to two per day. 相似文献

Responding to administrative staff and parental concerns, using modified reversal and withdrawal designs, two experiments evaluated a staff-managed feedback system to improve the hygiene and developmental skills of children in an infant/toddler center. Experiment 1 examined feedback designed to increase staff performance in checking and changing diapers, and recording those changes. A chart plus supervisory feedback produced increases in and maintenance of staff performance. Experiment 2 compared an existing staff management system with a “playchart” plus feedback in increasing careprovider-infant stimulation. The data (with follow-up on a new staff) supported the use of the new feedback system. Questionnaire data further supported the utility of the playchart system. 相似文献

The effects of public posting on speeding behavior on an urban highway were assessed using a reversal design. During baseline the percentage of drivers speeding was measured with a concealed radar unit. During the daily posting condition a highway sign was installed which provided feedback on the percentage of drivers not speeding yesterday and the best record to date. This sign was then covered and reintroduced. Results indicated that the sign was effective in reducing speeding behavior. Furthermore, the effects were most pronounced in reducing the speeds of the faster drivers. Next, daily and weekly postings were compared with the sign alone without numerical feedback: results revealed that the weekly posting condition was as effective as the daily posting condition, but that the sign had no influence when numbers were not posted. Finally, the weekly posting procedure remained effective during a 6-month follow-up condition. 相似文献

This paper addresses, and seeks to correct, some frequent misunderstandings concerning the claim that science is socially
constructed. It describes several features of scientific inquiry that have been usefully illuminated by constructivist studies
of science, including the mundane or tacit skills involved in research, the social relationships in scientific laboratories,
the causes of scientific controversy, and the interconnection of science and culture. Social construction, the paper argues,
should be seen not as an alternative to but an enhancement of scientists’ own professional understanding of how science is
done. The richer, more finely textured accounts of scientific practice that the constructivist approach provides are potentially
of great relevance to public policy.

Multipurpose senior centers are expanding their services to meet the demands of a growing population. Unfortunately, federal agencies have not matched this expansion with monetary support. Many senior centers hold fund-raisers to supplement their budgets, but the impact of these projects is rarely evaluated. This study assessed the effectiveness of a public posting strategy designed to increase donations to an ongoing fund-raiser for a multipurpose senior center. The fund-raiser, "Coupons for Caring," consisted of senior volunteers clipping grocery coupons from newspapers, sorting them, and attaching them to their respective products in local grocery stores. Grocery store customers were given the option of donating the coupons to the senior center or redeeming them when they purchased the products to which the coupons were attached. In the experimental condition, signs were posted that included visual and written instructions, feedback on the value of coupons donated by customers the previous week, and feedback on the overall amount of money donated to the senior center. The signs were posted near each cashier stand and at the front entrances of the grocery stores in a multiple baseline across grocery stores. The percentage of coupons donated to the senior center increased at each store after the signs were posted. 相似文献

Rhetorical theory has developed powerful criticisms of pretentions to objectivity, in the spirit of deconstruction and ideology critique. These critiques contain nihilistic tendencies when they become abstracted from the interactive social contexts upon which they depend for their own significance and efficacy. With a rich analysis of the social bases of communication sustained by its commitment to the project of deliberative democracy, the classic Pragmatism of John Dewey and G. H. Mead can provide an important corrective by orienting rhetorical theory toward reflective social-political engagement. 相似文献

Interdisciplinarity and the Development of Knowledge. The author is engaged in the question how to explain the development of scientific meanings of facts which does not coincide with producing them rather with processes of the scientists' public communication. So long as the facts are adjustable to the conventional theories of those discipline which the researcher belongs to this connection does not reveal perfectly clear. More instructive is a consideration of so-called anomalies. The author demonstrates with an example of the history of science that researchers in case of new phenomena use to borrow concepts from other disciplines for resolving the interpretative problems. It emerges a loose net-work of concepts. In this way the researchers are producing a disciplinary mixed public at the same time. This process is seen as an important phase of the development of new theories and, complementary, new disciplines. 相似文献

During the 1980s, we have witnessed an erosion in federal and state funding for the coordination of genetic services in state health departments. As this decade begins, the federal budget for the support of the national genetics program is less than half of the total available in 1980. In addition, priorities in state maternal and child health programs have changed, and genetic services have often received lower rankings aside of programs to improve prenatal care and to address problems such as teenage pregnancy. Clearly we are at a critical point for the future of genetics programs in the public health arena. Fortunately, despite the problems with funding and priority setting, important coalitions have been built during the past decade and continued advances in medical genetics have made it difficult for public health officials to ignore the potential impact of genetic services. Council of Regional Networks for Genetic Services (CORN) and the regional genetic services networks have provided opportunities for interaction and coordination between genetic services providers and public health officials that had not been available to any significant extent. The full potential of these coalitions has yet to be realized, but efforts in data collection, development of national guidelines and standards, and information sharing and networking have already had an influence on state genetic services programs. Continuing research on the genetics of chronic diseases and the influence of discoveries in molecular genetics will undoubtedly broaden the current scope of state public health programs in genetics, which all too often have been limited to newborn screening and administration of grants for genetic services. The regional and national genetic services programs should be strengthened and appropriate training programs should be developed in Schools of Public Health to provide the expertise and leadership that will be needed to guide the future of genetics in public health. 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

Participants ranging in age from 30 to 70 years free-recalled when they had learned public and private items of news. When responses were plotted in terms of age of participant at time of encoding, it was found that peak recall for public items of news was in the period when participants were aged 10 to 19 years whereas peak recall of private items of news occurred in the period when participants were aged 20 to 29 years. A second study confirmed this pattern of an early reminiscence bump for public news. It is proposed that these two components of the reminiscence bump reflect, respectively, a period of formation of generation identity in the second decade of life and a period of formation of intimate relationships in the third decade. 相似文献
