Consumers’ avoidance of information on red meat risks: information exposure effects on attitudes and perceived knowledge

In accordance with cognitive dissonance theory, individuals generally avoid information that is not consistent with their cognitions, to avoid psychological discomfort associated with tensions arising from contradictory beliefs. Information avoidance may thus make risk communication less successful. To address this, we presented information on red meat risks to red meat consumers. To explore information exposure effects, attitudes toward red meat and perceived knowledge of red meat risks were measured before, immediately after, and two weeks after exposure. We expected information avoidance of red meat risks to be: positively related to (1) study discontentment; and (2) positive attitudes toward red meat; and negatively related to (3) information seeking on red meat risks; and (4) systematic and heuristic processing of information. In addition, following exposure to the risk information, we expected that (5) individuals who scored high in avoidance of red meat risks information to change their attitudes and perceived risk knowledge less than individuals who scored low in avoidance. Results were in line with the first three expectations. Support for the fourth was partial insofar as this was only confirmed regarding systematic processing. The final prediction was not confirmed; individuals who scored high in avoidance decreased the positivity of their attitudes and increased their perceived knowledge in a similar fashion to those who scored low in avoidance. These changes stood over the two-week follow-up period. Results are discussed in accordance with cognitive dissonance theory, with the possible use of suppression strategies, and with the corresponding implications for risk communication practice.     

The Evaluation of Sports Sponsorships

This article considers how sports sponsorships are evaluated by sponsors. The important question is to determine whether a systematic approach is used in the light of the huge expenditures involved in sponsorships. The role of sports sponsorships in the promotional mix is discussed, as well as the evaluation of sports sponsorships. This study involved a sample of 28 sponsors in South Africa during 1988. A framework for the evaluation of sponsorships is presented for use by companies wishing to enter the world of sponsorship.     

Semi-core equivalence

Summary. The main requirements for equivalence of the core of an economy and the Walrasian equilibrium allocations are largeness and the freedom to form almost arbitrary coalitions in the Edgeworthian barter processes. We investigate whether constraints on coalition formation and coalitional barter alter these insights. Our notion of the semi-core imposes a restriction on the collection of formable coalitions that does not affect the fundamental equivalence property. Using our concept of the contract-core we show that additional constraints on coalitional barter can only be alleviated within an environment with sufficiently many formable coalitions: besides a contract-core equivalence theorem we show certain non-equivalence results.Received: December 11, 1995; revised version: September 17, 1996This revised version was published online in February 2005 with corrections to the cover date.     

A new risk-based design approach for hydraulic engineering

Hydraulic structures providing flood and coastal protection facilitate economic development as well as living areas and often converge with other infrastructure. There is a need for general guidance for analysing risks of hydraulic structures. This paper analyses two actual hydraulic engineering projects in the UK in which acceptable risk levels are incorporated in the design using a new risk-based design approach, taking consciously into account the influence of stakeholders, the legal framework as set by the Government, design-elements from different design-disciplines and funding.     

Common Ground, Complex Problems and Decision Making

Organisations increasingly have to deal with complex problems. They often use multidisciplinary teams to cope with such problems where different team members have different perspectives on the problem, different individual knowledge and skills, and different approaches on how to solve the problem. In order to solve those problems, team members have to share their existing knowledge and construct new knowledge. Theory suggests that negotiation of common ground can positively affect team decision making on the solution of complex problems, by facilitating knowledge sharing across perspectives. In a small scale study with student groups, external representations supported by a specific negotiation ontology were used to facilitate negotiation by encouraging participants to make their beliefs and values explicit. Results showed that the external representations supported clarifying contributions to group members and increased group participation in discussions.     

Rethinking determinants of ICT acceptance: Towards an integrated and comprehensive overview

In the contemporary ICT environment, we are confronted with a growing number of failing innovations. New technological innovations often fail because too much attention is still given to (technical) product-related features without taking into account the most important parameters of user acceptance. In addition, suppliers of ICT products often lack accurate insight into the distinguished profiles of their (potential) target audience. In this article theoretical considerations and empirical results on this matter are highlighted. First of all, an approach is proposed in which more traditional and often scattered vision(s) on adoption determinants are broadened into an integrated framework. The approach provides a stronger base for better targeting of (new) users of technologies. Secondly, the authors elaborate on this by rethinking these determinants with regard to later adopters. Later adopters (or even non-adopters/users) are often ignored in technology acceptance research. However, especially for policy purposes, the understanding of why people do not adopt or do not use ICT is strongly relevant in the light of the development of an inclusive information society. Both approaches are illustrated by case studies starting from a common list of nineteen ICT appropriation determinants. This framework enables to better profile both earlier and later adopters as well as it allows to formulate recommendations how to bring innovations in the market. Summarizing, this contribution offers an integrated approach on technology acceptance research by bridging the gap between a market and a policy-oriented point of view.     

European Antitrust Policy 1957–2004: An Analysis of Commission Decisions

This paper provides a survey of  European antitrust law enforcement since its foundation in the Treaty of Rome of 1957 up to and including 2004. We present a complete overview and statistical analysis of all 538 formal Commission decisions under Articles 81, 82, and 86 of the European Community Treaty. We report a range of summary statistics concerning report route, investigation duration, length of the decision, decision type, imposed fines, number of parties, sector classification, nationality, and Commissioner and Director General responsible. The statistics are linked to changes in legislation and administrative implementation, thereby providing an historical overview that summarizes the Commission’s work in the area of antitrust. One or more appeals were filed with respect to 161 of the 538 decisions. We estimate the determinants of the size of the imposed fine and probability of appeal when an infringement has been found.
