Fair and Fast Convergence on Islands of Agreement in Multicriteria Group Decision Making by Logical Navigation

Reasoning on multiple criteria is a key issue in group decision to take into account the multidimensional nature of real-world decision-making problems. In order to reduce the induced information overload, in multicriteria decision analysis, criteria are in general aggregated, in many cases by a simple discriminant function of the form of a weighted sum. It requires to, a priori and completely, elicit preferences of decision makers. That can be quite arbitrary. In everyday life, to reduce information overload people often use a heuristic, called “Take-the-best”: they take criteria in a predefined order, the first criterion which discriminates the alternatives at stake is used to make the decision. Although useful, the heuristic can be biased. This article proposes the Logical Multicriteria Sort process to support multicriteria sorting within islands of agreement. It therefore does not require a complete and consistent a priori set of preferences, but rather supports groups to quickly identify the criteria for which an agreement exists. The process can be seen as a generalization of Take-the-best. It also proposes to consider one criterion at a time but once a criterion has been found discriminating it is recorded, the process is iterated and relevant criteria are logically combined. Hence, the biases of Take-the-best are reduced. The process is supported by a GDSS, based on Logical Information Systems, which gives instantaneous feedbacks of each small decision and keeps tracks of all of the decisions taken so far. The process is incremental, each step involves low information load. It guarantees some fairness because all considered alternatives are systematically analyzed along the selected criteria. A successful case study is reported.     

Addressing the Texting and Driving Epidemic: Mortality Salience Priming Effects on Attitudes and Behavioral Intentions

Texting while driving is becoming a problem of epidemic proportion, causing thousands of fatalities each year. However, surprisingly few academic studies to date have examined this issue in a social marketing context. We address this research void by reporting the findings of two empirical studies—the first, an exploratory study of drivers' perceptions of texting while driving; the second, an experimental examination of the relative effectiveness of mortality salience (MS) primes in public service announcements (PSAs). Employing theory derived from the MS literature, we find that when verbal and/or visual cues to death/dying were used, participants' attitudes and behavioral intentions were altered in a positive direction. As compared to a control group, the primed PSAs produced less favorable attitudes and reduced intentions to text while driving in the future. Implications of these findings for consumers, social marketers, and policymakers are discussed, and future research directions are provided.

‘Never take pity’: an average French boxer’s ethnobiography

Based on a long-term ethnographic study of a group of French boxers, this article retraces the biography of one of its members. Éric was an average boxer who never truly mastered the art of dodging his opponents. He never left the ranks of amateur boxing either, although in fact he never truly hoped he would step into the limelight reserved for the very few champions who make it. His anonymous and relentless commitment to boxing was in fact filled with a different meaning that his ethnobiography brings to light. His commitment to boxing can be better understood in light of the trials he faced in “the poor life”, a life he described as flavorless, mired in unemployment and survival delinquency. Despite his repeated defeats in the ring, for him boxing was the only part of his identity that elevated his status and set him apart from those who only had the streets to hang out on. By revealing the meaning he gave to his pugilism, Éric’s ethnobiography offers a new perspective on the links between boxing, violence, and poverty. It also paves the way for exploring the dark side of a leisure activity and its struggles that extend far beyond the ring itself.     

Khat-chewing in liminal leisure spaces: British-Somali youth on the margins

Khat-chewing, a controversial leisure activity within the Somali diaspora in Britain, has received little attention within the academic field of Leisure Studies. This paper reports on ethnographic research to provide insights into the unique locations where young British-Somali men chew khat, exposing the liminal qualities of such localities. The paper begins with an overview of the contentious position khat-chewing occupies within Somali communities in Britain, highlighting reasons why young British-Somali men hide their association with the leisure practice. The discussion that follows considers how young male khat users conceptualise spatial environments, exposing how these locations temporarily produce a dual sense of privacy and sociality. The ambiences of such temporary leisure spaces remain open to the prospect of discovery, resulting in the use of discretionary tactics to maintain a sense of secrecy. In this context, we discuss how khat-chewing offers a sense of cultural identity and belongingness while also marking young British-Somali men as outsiders – even within their own communities.     

Place attachment,host–tourist interactions,and residents’ attitudes towards tourism development: the case of Boa Vista Island in Cape Verde

A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista.     

Approximating the distribution of the two-stage least squares estimator when the concentration parameter is small

This paper presents a new approximation to the exact sampling distribution of the instrumental variables estimator in simultaneous equations models. It differs from many of the approximations currently available, Edgeworth expansions for example, in that it is specifically designed to work well when the concentration parameter is small. The approximation is remarkable in that simultaneously: (i) it has an extremely simple final form; (ii) in situations for which it is designed it is typically much more accurate than is the large sample normal approximation; and (iii) it is able to capture most of those stylized facts that characterize lack of identification and weak instrument scenarios. The development leading to the approximation is also novel in that it introduces techniques of some independent interest not seen in this literature hitherto.     

Macroforces driving change into the new millennium — major challenges for the hospitality professional

The fast pace of change will present many challenges in the new millennium. The success of the leader of tomorrow will depend on how well he or she is able to identify the forces that will drive change, invest in industry leading competitive methods that will take advantage of the opportunities presented by these forces and consistently allocate resources to these methods. Identifying the forces driving change is the most challenging aspect of this co-alignment concept. This paper explores the macroforces, which can be expected to drive change, and possible impact they will have on the hospitality organization. These forces include: globalization and economic change, a knowledge-based environment, the future of labor and quality in service delivery systems, and the growing consumer desire for improved well-being. These forces are presented along with the key variables making them up with the goal of understanding their complexities and interdependencies.     

Fairness of prices,user fee policy and willingness to pay among visitors to a national forest

Imposing user fees in Nature-Based Tourism (NBT) contexts has been a controversial issue. Based on the notions of justice and fairness, this study extended previous work examining the relationship between attitudes toward user fees and spending support. In a proposed structural model of price fairness, fee spending support, and willingness to pay (WTP), this paper identified the antecedents of WTP user fees, and empirically examined to what extent the data fit the model. Furthermore, the moderating role of place attachment in the model was investigated by using multiple-group structural equation modeling. Subjects (n = 562) were recreational tourists to a forest area in the southeast U.S. Results revealed that spending support partially played a mediating role in the relationship between perceived price fairness and WTP user fees. A multiple-group invariance test also demonstrated that while the degree of place identity moderated the effect of price fairness on spending support, the degree of place dependence did not influence the relationships among the antecedents of WTP.
