A Communication Perspective on Video Lottery Terminals

Video Lottery Terminals (VLT) are associated with pathological gambling and with most of the requests for help in combating gambling addiction. Embeddedness of a person in his or her social network is among the communicational factors that may help explain this phenomenon. To verify this, we compared ego networks of VLT gamblers, of gamblers of games with low request for help and of VLT gamblers in treatment (n = 90). The networks of regular VLT gamblers are small and dense and offer little social support. Gamblers in treatment also have small networks, but they are less dense, have more components and offer more social support. Networks of gamblers with low requests for assistance are approximately twice the size as those of VLT gamblers, are sparser and offer more companionship. In conclusion, the VLT gambler is not an isolated individual, but rather an individual ‘shut-in’ a small network of tightly knitted relationships.     

The theatre of war: art,organization and the aesthetics of strategy

Recent Anglo-Saxon writings on management regard “vision” as being of strategic importance to leadership. Whilst such an approach has led to socio-psychological inquiries into “visionary leadership” the equally relevant phenomenological “philosophy of the eye” has remained unexplored by organizational scholars. This European philosophical tradition is closely connected to theories of art. In three cases, it will be shown how continental reflection on the strategic management of warfare has taken the eye seriously and thereby gained insights from aesthetics. It will be argued that the understanding of civilian strategic management also might benefit from such s connection between Strategy and Art.     

Risk Management for Hazardous Materials Transportation: A Local Study in Lyons

A probabilistic risk assessment study has been undertaken in the French city of Lyons. The issue was to know whether it was justified to forbid hazardous material lorries in the city center and to divert them through the suburbs. Therefore, two routes, the City Center route and the Suburban route were compared. This paper describes the analysis and shows how the results were used in the decision-making process. It also lists the difficulties that are encountered when trying to incorporate formal risk analysis into actual decision-making processes. The risk analysis showed that rerouting is an effective option with respect to all criteria. The mathematical expectation of the number of deaths is divided by three, the reduction on the annual frequency of catastrophic accidents is even more important (about one order of magnitude for accidents involving more than 50 deaths). The spatial analysis proved that the risk was more evenly distributed along the Suburban route. However, the annual expected number of death is low: 0.5 in the worst case. So traditional decision-making approaches do not indicate the necessity of rerouting. Such a situation is believed to be typical for risk management of major hazards. In Lyons, the use of a very small risk aversion factor is sufficient to justify the rerouting option on a formal decision-aiding basis. This is rather unusual, but it is thought that the recognition of the importance of risk aversion by the decision-makers themselves is a very positive outcome from this study.     

When Robert E. Park was (Re) writing “the city”: Biography,the social survey,and the science of sociology

Sociological production is a situated and embodied activity carried out by individuals inserted in actual social relations. Considering that this feature has an influence upon the content of scholarly literature and that it can be revealed in the scientific text itself, I propound a new interpretation of the writing process of Robert E. Park's “The City,” the famous paper he published initially in 1915. Customarily depicted as a manifesto for an autonomous urban sociology, I argue on the contrary that its general economy has to be linked to Park's biographical background. When he affiliated with the Sociology Department at the University of Chicago, Park was brought to teach a course on the social survey. “The City” was to be the academic expression of his point of view on the topic. Park's biographical encounters with some active promoters of the social survey approach are evidenced and their influence onhis 1915 essay is carefully analyzed, showing notably that curious intellectual omissions in “The City” can be traced back to these previous encounters. Park's latter texts, and the 1925 revised version of “The City” in particular, are shown to provide the interwar sociologists with a peculiar narrative about the history of sociology: Park's predecessors are deliberately confined in a pre-scientific stage of the discipline and Park's original essay is presented as a seminal research program destined to be later fulfilled by the newly established urban sociologists. The author wishes to thank the anonymous reviewers for their insightful and helpful comments on the first draft of the paper, Lawrence T. Nichols for his kindly editorial guidence, and Jacques Marquet and Felice Dassetto for their marerial support.     

Mean-preserving changes in risk with tail-dominance

In this paper, we consider a class of mean preserving increases in risk such that all risk-averse decision makers respond to an increase in risk by reducing the level of their risky activities. The type of increase in risk that we consider is based on the notion of tail dominance which generalizes other cases previously discussed in the literature.L.
