Community safety promotion at local,regional, and national levels. Summary report from a workshop on local organizing and societal contributions with regard to the development of Safe Communities,held at the Third International Conference on Safe Communities,June 6-8, 1994, Harstad,Norway

Aim The aim of this review was to determine the extent to which the effectiveness of countermeasures for preventing alpine skiing injuries has been evaluated. Methods The methodology involved a critical review based on the available international literature and sports equipment standards, as well as consultation with experts in the field. Where possible, the review focused on controlled trials. Results Key injury countermeasures in skiing identified in this review include physical conditioning programmes, ski-bindings and their timely release, professional adjustment of ski-bindings and the use of mechanical testing devices for this, design of ski pole handles, helmets for children (and adults), ski patrollers, skier education, speed control on the slopes and safe lifting equipment. A tabular categorisation of the types of evidence for the effectiveness of injury countermeasures is presented. This demonstrates that the weight of evidence is generally based on a combination of data-based or biomechanical testing evidence and informed opinion/anecdotal evidence. There is minimal evidence based on controlled trials in the field. The most evaluated countermeasures are ski bindings and ski pole handles. Properly adjusted ski bindings have the potential for a 3.5-fold reduction in lower extremity injuries, particularly knee injuries. Ski pole handle design needs further innovation and attention. An immediate concern is the generally poorer standard of children’s equipment, ski bindings and their adjustment. Conclusion Skiing is a sport that is growing in popularity, but with a need for controlled trials of its injury prevention countermeasures. This review provides a basis for further action in injury prevention research, development and implementation.

Trust Promoting Seals in Electronic Markets

Abstract

In order to promote web sales, companies conducting electronic commerce are constantly seeking viable and efficient ways to increase web traffic. One approach is to build consumers' trust, and ultimately to increase web sales. Many business-to-consumer online merchants follow this approach and display trust-promoting seals on their websites. However, whether these seals really fulfill the tasks they have promised has remained unexplored. This study empirically examines the influence of trust-promoting seals on consumers' online purchasing decisions. The results show that the trust-promoting seals are generally effective in promoting web sales, and some seals enhance promotion better than others.     

The Psychological Influences of Threat on B2C E-commerce Adoption: An Extended Study and Explanatory Framework

In order to better understand how internet users actually decide to conduct business transactions or related activities in a B2C e-commerce environment, this article adds a new lens of study by investigating the roles of Threat Appraisal (TA) and Perceived Coping Appraisal (PCA) from the end user's perspective. Based on established academic theories and relevant industrial practices, it is suggested that TA and PCA are critical behavioral components influencing the user's intentions to participate in online transactions. These functions serve as important inputs to formalizing our understanding of how services offered by e-commerce websites are utilized.     

The Response to the Commitment with Block-Leader Recycling Promotion Technique: A Longitudinal Approach

SUMMARY

This article focuses on the study of the changes in consumers' recycling beliefs, attitudes, and behavior due to the application of one promotion technique: a commitment by block leader technique characterized by the agreeing participant signing a request or statement in which s/he makes a commitment to recycle as a result of the encouragement of a person who belongs to the same social circle. We therefore carried out a quasi-experimental work whose results enable us to explain the response to this recycling promotion technique. It makes a contribution to existing environmental literature by (1) systemizing the set of existing doctrines in order to explain the response to this recycling promotion technique, and (2) revealing the effects of this technique on people's beliefs and attitudes. The practical implications that may stem from these contributions are of an educational nature and should be of use to the public management of promotion campaigns.

The Significance and Insignificance of Demand Analysis in Evaluating Promotion Programs

The estimated effects of promotion on demand are often small and insignificant. Yet, the estimated effects of promotion on industry profit are often positive and large. This puzzle is explained by demonstrating that (in)significance of promotion in a demand equation does not imply, and is not implied by, (in)significance of promotion in an industry profit equation. A Monte Carlo example is provided. The econometric modeling implications are discussed. The short-run marginal effect of a dollar of generic beef promotion on slaughter cattle industry profit is estimated to be about $9.84 with a standard error of 3.77 for 1997.
