Racial Wage Disparity in US Cities

This paper estimates the conditional wage gaps between black and white full-time male workers at the metropolitan statistical area (MSA) level using data from the 1990 and 2000 U.S. Censuses. The magnitudes of the wage gaps are found to vary substantially across location. As predicted in Becker's (The economics of discrimination, University of Chicago Press, Chicago, 1957) seminal theory on wage discrimination, we find that the wage gaps are greater in MSAs that have a larger proportion of black workers in the labor force. This is the most consistent result across all specifications and years. We also find the gaps to be greater where there is an overrepresented black population in jail and a more segregated population if the MSA is in the South. The proportion of workers covered by a collective bargaining agreement in the private sector is associated with greater relative black earnings. We find that although the relationship between race and wages has diminished over time as famously suggested in Wilson (The declining significance of race: Blacks and changing American institutions, University of Chicago Press, Chicago, 1978), the significance of race remains.     

THE HARMS SHOE COMPANY: DEVELOPMENT OF A COMPUTER MODEL FOR THE CLASSROOM

This paper describes a case that examines five key topics in production and operations management [1]—forecasting, inventory control, transportation planning, aggregate planning, and the disaggregation of the aggregate plan—in an integrated, realistic manner for upper-level undergraduate business majors [3]. The case structure stresses the linkage of these interrelated subjects and supplements the regular classroom presentations dealing with them. The case relies on computer calculations at each stage to provide the information input for calculations at the next stage. It is a static model with a twelve-month planning horizon. Students complete several exercises and assume several roles as the case unfolds. They act on their own in filling some roles and as members of teams in performing others. They do not compete with each other, as the purpose of the case is to help them develop an appreciation of the factors that persons performing the role must consider.     

Reflections on the Voluntary Self-Exclusion of Gamblers and the Law-Suits against Ontario Lottery and Gaming Corporation

Legalized gambling in Canada is governed by Provincial legislation. In Ontario, the Ontario Lottery and Gaming Corporation is responsible for all aspects of gambling in the Province. There have been a number of recent lawsuits against this Crown agency of the Government of Ontario by gamblers, most of which have been settled or otherwise resolved. A recent class-action lawsuit on behalf of thousands of Ontario gamblers against this agency raises a number of interesting questions regarding the issue of responsibility and liability. The questions surround the issue of self-exclusionary practices of gamblers who deem themselves in need of external intervention in order interesting questions regarding the issue of responsibility and liability. The questions surround the issue to abstain from further gambling. A contract is voluntarily signed by the self-excluding gamblers whereby their further attendance at gaming venues is prevented and could be punishable by law. Where the gaming venues have failed to enforce the terms of this contract, gamblers have continued to gamble at these establishments. The class-action lawsuit stems from the grievances of these self-excluded gamblers who were not turned away. Relevant psychological theories and recent findings pertaining to gambling are reviewed and questions relevant to these grievances are discussed in favor of government responsibility and liability toward gamblers.     

Dynamic Graphics for Exploring Spatial Data with Application to Locating Global and Local Anomalies

We explore the application of dynamic graphics to the exploratory analysis of spatial data. We introduce a number of new tools and illustrate their use with prototype software, developed at Trinity College, Dublin. These tools are used to examine local variability—anomalies—through plots of the data that display its marginal and multivariate distributions, through interactive smoothers, and through plots motivated by the spatial auto-covariance ideas implicit in the variogram. We regard these as alternative and linked views of the data. We conclude that the most important single view of the data is the Map View: All other views must be cross-referred to this, and the software must encourage this. The view can be enriched by overlaying on other pertinent spatial information. We draw attention to the possibilities of one-many linking, and to the use of line-objects to link pairs of data points. We draw attention to the parallels with work on Geographical Information Systems.     

Magnification of affect using frame-by-frame film analysis

Frame-by-frame film analysis of social interaction enhances the observer's ability to make inferences about the affective component of the interaction by allowing a detailed and precise review of the interpersonal behavior. An example of leave-taking behavior between a parent and preschool child is presented. The magnification of the interaction by repeated slow-motion viewing allows one to draw out emotional behavioral components that occur too rapidly to be perceived at normal speed. The technique is applicable to any type of interpersonal analysis.     

Psychological Testing in a Multicultural Society: Universal or particular competencies?

This paper deals with the issue of whether standardised psychological tests, in particular intelligence tests, are suitable for assessing ethnic minorities in a multicultural society. Three different levels of analysis are applied to address this question: the socio-political, the ethical and the test-theoretical level. The socio-political level of analysis highlights the obstacles ethnic minorities encounter when attempting to settle in a new society, and the measures that could be taken to remove these obstacles. The ethical level of analysis elucidates our point of view that: (1) universal and particular competencies both have clear roles in the lives of individuals and groups, but; (2) these can not always be reconciled in educational settings; which (3) calls for various choices: between certain political commitments (e.g. the right to cultural differences), and the consequences of these (e.g. excluding those who are different from full participation in specific, mainstream roles and functions). Central to the paper is our sense that the testing of ethnic minorities "tests" the limits and possibilities of intercultural education.
