A Reply to Gambino's "An Epidemiologic Note on Verification Bias: Implications for Estimation of Rates"

While two-stage designs in problem gambling research are expensive and relatively difficult to execute, they have the potential to yield more accurate prevalence estimates as well as valuable additional information about gambling and problem gambling in the community. However, gains in precision are heavily dependent on the accuracy of the screening methods used and the sample sizes involved. Sound practice requires reliable information about the variances and confidence levels associated with different screens. In the spirit of contributing to the ongoing dialog about ways to improve the measurement of problem gambling, we examine several reasons to question whether the revised estimates offered by Gambino are in fact an improvement.     

Supplier involvement in product development in the electronics industry: A case study

The movement of activities earlier in the product development process requires a re-examination of the total supply network. The objective of this paper is to determine the degree of early supplier involvement (ESI) that exists between a multinational electronics company and its key suppliers, in terms of depth of integration, information exchange and buyer–supplier relationships. The paper provides insights into the strategic factors that affect the dynamics of the ESI process. The research indicates that there are considerable impediments for those participants responsible for establishing and managing the implementation of ESI. A number of strategic insights are identified that explain the existence of the impediments to the ESI process. Finally, based upon the findings a number of lessons are highlighted for organisations considering the adoption of the ESI process.     

Role Performance and Person Perception: Toward an Interactions Approach*

This paper examines and critiques the manner in which one strand of attribution theory has addressed the relationship between role performances and person perception. An interactionist approach is formulated as an alternative, and an experiment is designed to test its viability. The experiment supports our hypothesis that the informational value of “in-role” performances is similar to the informational value of “out-of-role” performances, and that neither type of performance is consistently more informative than the other. Further, it is suggested that the informational value of role performances is not adequately explained by the in-role/out-of-role dichotomy. The interactionist conception of role, combined with a notion of informal role types, provides a more accurate understanding of role performance and person perception.     

The value of a statistical life: A comparison of two approaches

Using an original data set, this article presents the first effort to compare systematically the values of a statistical life obtained from the two main methodologies existing in the literature—the revealed-preference approach (wage-risk analysis) and the contingent-valuation approach—applied to the same sample of individuals. A survey was conducted in the Montreal area with a questionnaire containing two series of questions: one set of contingent-valuation questions and one set of questions pertaining to the information necessary for performing a wage-risk study. The results show that the values of a statistical life obtained from each method are different from each other.This research was supported by the Fonds F.C.A.R. of the Quebec government, the Social Sciences and Humanities Research Council, and by the Fondation Mercure of l'École des Hautes Études Commerciales. The authors want to thank the editor and an anonymous referee for their useful comments.     

Strategic planning for MIS

This article report on a study of the strategic decision to develop computerized management information systems (MIS) in 32 business organizations. THe findings suggest that this decision is a complex policy decision which involves protracted environmental negotiations, a high and escalating commitment of organizational resources, and extensive organizational preparation. Eleven organizational and environmental factors which influence the decision are identified through a literature review. The influence of these factors on the success of the decision is examined and recommendations are made for managing the decision-making process to insure improved decision outcomes.     

The relationship between lead and crime

This study investigates the association between air-lead levels and crime rates across 2,772 U.S. counties. Data for the analysis come from the Environmental Protection Agency, the Bureau of Census, and the Federal Bureau of Investigation. Results suggest that air-lead levels have a direct effect on property and violent crime rates even after adjusting for general levels of air pollution and several structural covariates of crime. We also find that resource deprivation interacts with air-lead levels. The association between air-lead levels and crime rates-property and violent-is strongest in counties that have high levels of resource deprivation and weakest in counties that have low levels of deprivation. This interaction is consistent with arguments and evidence in the health care literature that populations most at risk of lead poisoning are least likely to get the resources required to prevent, screen, and treat the illness.
