Effects of public posting on driving speed in Icelandic traffic

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.     

The University as Learning Community

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.     

Development and Validation of the Screen for Adolescent Violence Exposure (SAVE)

Empirical evidence was provided on the utility of the Screen for Adolescent Violence Exposure (SAVE) in assessing adolescent exposure to school, home, and community violence. The SAVE was empirically developed on 1,250 inner-city adolescents, and obtained excellent reliability and validity. Both exploratory and confirmatory factor analyses identified three factors: Traumatic Violence, Indirect Violence, and Physical/Verbal Abuse. The SAVE demonstrated utility in classifying high- and low-violence participants, and correlated significantly with both objective crime data and theoretically relevant constructs (anger, posttraumatic stress symptoms, and internalizing/externalizing problems). Thus, the SAVE provides measurement of the stressor criterion associated with posttraumatic stress disorder, and allows quantification of severity of violence exposure by setting.     

ALAIN LOCKE AND COMMUNITY

Locke consistently argues for the importance of cosmopolitan identity, i.e., cultural-citizenship. Paradoxically, he also argues for the importance of particular, local, and racial/ethnic identities. People have a natural instinct that Locke terms a consciousness of kind, to bond with persons in relatively closed communities. Communities are not natural social groups for Locke, but historical social constructions. I argue that Locke's ethical and conceptual paradox is revolved by considering the relationship between instincts and particular social groups as asymmetrical; that groups are inherently constructed, and thus require continual revaluation. Particular communities are, at best, Gemeinschaft.     

PROMPTING PATRON SAFETY BELT USE AT A SUPERMARKET

We used a reversal (ABAB) design to assess the effects of a personal prompt on safety belt usage by grocery store patrons. A personal prompt delivered by grocery carriers resulted in a 12% increase in the number of patrons exiting the parking lot with their safety belts buckled. This simple, low-cost intervention offers potential savings to society from increased safety belt use.     

PROMPTING TECHNIQUES TO INCREASE THE RETURN RATE OF MAILED QUESTIONNAIRES1

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.     

An exploration of the interplay between psychological sense of community,social identification and salience

Past research indicates that there is a strong relationship between the constructs of psychological sense of community (PSOC) and social identification. The current study draws on data (N = 219) examining participants' membership in a number of different communities to present an examination of the relationship between these constructs. In particular, the study examines the relative strength of the separate aspects of social identification (based on Cameron's 2004, Three Factor Model of Social Identification) as predictors of overall PSOC, accounting for situational salience. Results indicate that Ingroup Ties is consistently the strongest predictor of PSOC and that the strength of Ingroup Affect and Centrality alter according to the group or community context. The theoretical implications of these results are discussed in terms of the interplay and overlap of these important community processes. Copyright © 2005 John Wiley & Sons, Ltd.     

Developmental issues in indigenous psychologies: Sustainability and local knowledge

The present paper endeavours to discuss some of the potential issues inherent in the developmental work for indigenous psychologies, especially in the Western context. The discussion is made around two topical issues, sustainability and local knowledge. The developmental processes in indigenous psychologies are influenced by the inter- and intracommunity environment. It is important to trace the development of local knowledge in a sustained community environment. The cross-fertilization of ecological perspectives with indigenous psychological knowledge can enlighten our understandings of global issues in psychology as well as the applications of psychological knowledge to a local context. A theoretical model is proposed to highlight major social psychological processes in a participatory community environment − the model is expected to address essential contentious issues to the future of a globalized psychology, especially the way integrated local knowledge can lay the foundations of a globalized indigenous psychology.
