Cycle avoiding trajectories,strategic agendas,and the duality of memory and foresight: An informal exposition

This paper considers the notion of cycle avoiding trajectories in majority voting tournaments and shows that they underlie and guide several apparently disparate voting processes. The set of alternatives that are maximal with respect to such trajectories constitutes a new solution set of considerable significance. It may be dubbed the Banks set, in recognition of the important paper by Banks (1985) that first made use of this set. The purpose of this paper is to informally demonstrate that the Banks set is a solution set of broad relevance for understanding group decision making in both cooperative and non-cooperative settings and under both sincere and sophisticated voting. In addition, we show how sincere and sophisticated voting processes can be viewed as mirror images of one another — embodying respectively, “dmemory” and “foresight.” We also show how to develop the idea of a “sophisticated agenda,” one in which the choice of what alternatives to propose is itself a matter of strategic calculation.     

Resources of supplemental security income recipients

In order to receive payments under the Supplemental Security Income (SSI) program, an aged, blind, or disabled person's countable resources must fall below specified limits. The current limits are +2,000 for an individual and +3,000 for a couple. In 1987, when the data were collected for this study, these limits were +1,800 for an individual and +2,700 for a couple. This study found that the resource levels of most SSI recipients were well below the 1987 limits. A majority of SSI recipients had less than +100 in countable resources, and only about 12 percent of SSI recipients had more than +1,000 of resources. These low levels of resources ensure that relatively few recipients become ineligible for SSI payments because of resource accumulation. The most common forms of countable resources held by SSI recipients were cash, checking accounts, and savings accounts.     

A study of Supplemental Security Income awardees

Since its enactment in 1974, the Supplemental Security Income (SSI) program has had a stable caseload of about 4 million recipients. Hidden by this unchanging total is the fact that nearly 9 million persons were served by the program from 1974 to 1986. This study explores some SSI program dynamics by following a group of SSI awardees for a period of 4 years from the initial receipt of award in 1981. Many of these awardees had previous contact with the program either through a previous award or a denial. About 60 percent of the awardees were eligible at the end of the 4-year period. Most persons who became ineligible did so within the first 6 months after the award.     

The nuclear family: Correspondence in cognitive and affective reactions to the threat of nuclear war among older adolescents and their parents

In order to assess the relationship between family members' cognitive and affective responses to nuclear war issues, 317 college students and their parents (n=559) independently completed a multifaceted questionnaire that included items concerning personal reactions, predictions, opinions, and attitudes about nuclear war. Results revealed a negligible relationship between the responses of college students and their parents, although the level of concordance between mothers and fathers was somewhat greater. Moreover, parents and students were relatively poor at predicting each others' nuclear threat attitudes, and the strength with which an attitude was endorsed did not enhance its predictability. Results are discussed with regard to heterogeneity in attitudinal and affective reactions within families, and with regard to the idea that infrequent communication concerning nuclear war issues may be occurring.Portions of this article were presented at the meeting of the American Psychological Association, Los Angeles, California, August 25, 1985.Interested in clinical and counseling psychology, the psychological effects of the threat of nuclear war, and parent training.Interested in counseling psychology, nuclear war issues, and the concept-specific measurement of emotionality.Interested in counseling psychology, nuclear war issues, and factors influencing custody decisions.

A method for group identification of hair infected with Microsporum

A method for identifying the group appurtenance of biological objects from subjects suffering from various diseases is developed. The method can be used in examination of putrefactive objects (blood, secretions, hair, etc.) and in cases when the group appurtenance cannot be identified by other methods.     

Collaboration over Adaptation: The Case for Interoperable Communications in Homeland Security

Analogizing the U.S. Department of Homeland Security to a corporate conglomerate consisting of multiple, formerly independent operating units with little in common and even less history of cooperation, this response to Professor Charles Wise prescribes the "bitter medicine" of interoperable communications. The critical function of assuring homeland security and disaster preparedness cannot depend on the uncertain trajectory of adaptive response.
