Systematic analysis of multiple voting rules

For a class of voting rules, which includes Approval and Cumulative Voting, it is shown how to find and analyze all possible outcomes that arise with a specified profile, and, conversely, how to start with a potential region and determine whether there exist supporting profiles. The geometry of these regions is determined by the “Reversal symmetry” portion of a profile; i.e., components of the Asucc Bsucc C, Csucc Bsucc A{Asucc Bsucc C, Csucc Bsucc A} type.     

Simmel at a Distance: On the History and Systematics of the Sociology of the Stranger

Abstract

Concepts made famous in “classic” works are often cited in ways that deviate from their original meaning. This often leads to cumulative confusion rather than the advancement of insight. Scrutiny of such confusions may provide fruitful points of departure for systematic codification.

In the literature which refers to Simmel's excursus on “The Stranger,” four areas of confusion can be identified

1. Simmel's conception of the stranger has periodically been equated with the concept of the “marginal man,” a very different social type;

2. Simmel's conception of the stranger has often been equated with the newly arrived outsider, another distinct type;

3. the distinction (only latent in Simmel) between strangers as individuals and stranger communities has not been articulated in later studies; and

4. the significance of the variety of ways in which Simmel used the metaphor of simultaneous closenss and remoteness has been obscured.

Clarification of the issues related to these four areas of confusion lays the basis fora typology of stranger statuses (Guest, Sojourner, Newcomer, Intruder, Inner Enemy, Marginal Man) and a related paradigm presented to assist in organizing the sociology of the stranger in a more systematic fashion.     

Cognitive and Affective Factors Which Influence Downtown Behaviors

Abstract

Data collected on perceptions of downtown Atlanta are used to explore the impact of cognitive and affective assessments of place on the frequency with which individuals go downtown for shopping, business or professional services, and for entertainment activities. Findings include: (1) social background variables generally exert only weak effects on cognitive and affective responses to downtown Atlanta; (2) affective identification with downtown exerts a positive, significant, and powerful effect on the frequency of using downtown for shopping and business activities; (3) non-Whites, city residents, and singles are more likely to go downtown for entertainment activities than Whites, suburbanites, and married respondents; and (4) images of downtown, affective identification, and positive assessments of downtown municipal services encourage participation in downtown entertainment activities. The analysis strongly suggests that behaviors are influenced by the meanings and evaluations people create for an area.     

Costs,Benefits, and Management Considerations of a Prepaid Student Dental Health Plan

Abstract

The Student Dental Health Program (SDHP) is an open panel, prepaid dental insurance plan at the University of Alabama in Birmingham. The program was developed primarily to provide optimal dental health service; however the SDHP also serves educational and research functions that are consistent with the objectives of the university. The student bodies of the Schools of Dentistry, Medicine, Nursing, and Optometry constitute the enrollee population.

Total cost rose from $18,418 in 1969–70 with 862 enrollees, to $70,930 in 1975–76 with 1,618 enrollees. During the same period the number of procedures completed increased from 2,868 to 6,796, with the average cost per procedure increasing from $6.42 to $10.44. The number of restorative services declined and preventive services increased. In 1976–77 benefits per student treated were estimated at $80 as compared to the annual fee of $48. The value of unmet needs upon entrance to the program averaged $59 per enrollee in 1974–75. By 1976–77 this figure was reduced to $26 due to implementation of an initial screening. The program is self-supporting due to a variety of cost containment measures. On balance, the program can be considered successful and beneficial to all parties concerned.     

Cost of Including Males in a University Rubella Immunization Program: A Recommendation to Change a Discriminatory Policy

Abstract

Twenty-seven University of Rochester students developed clinical manifestations of rubella during 1976–77. Twenty-five were male and had not been immunized against this disease; 18 required infirmary care costing $4,876. On the basis of data for freshman males, a cost analysis demonstrates the feasibility of changing the university policy which encourages immunization only of females to encouragement of either selective or mass immunization of all males as well. Immunization during childhood with combined MMR vaccine is least expensive and should be encouraged. In certain circumstances, selective immunization of susceptible males may be less expensive than the present selective policy, which leaves males at risk.
