The uncovered set in spatial voting games

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set.     

National Support Income Scheme For Australia: An Economic and Statistical Study

This study attempts to demonstrate the financial viability and economic soundness of adopting a National Support Income Scheme for Australia. The concept, designed to create an environment in which jobs are available for all, relies on three basic propositions including a reduction in wages and other incomes in exchange for receipt of the support income. The demonstration, based on the latest published statistics, indicates that adopting this scheme for Australia can be financially and economically justified.     

A Non-punitive Paradigm of Probation Practice: Some Sobering Thoughts

Dr L. R. Singer, Assistant Chief Probation Officier, Merseyside Probation Service, Rainford Hall, Crank Road, Crank, St Helens, Merseyside WA11 7RP. Summary The Government White Paper Crime, Justice and Protecting thePublic proposes a radical change for probation practice. Henceforthprobation work will no longer be an alternative to punishmentbut an alternative form of punishment. This article challengesthe conceptual and practical appropriateness of applying thenotion of punishment to the probation context. Probation officers,it is argued, are concerned with establishing rules for probationersand not inflicting pain on them. An alternative non-punitiveparadigm of probation practice is described. The paradigm isbased on the joint supervisory aims of support and surveillancewhich are implemented through the methods of counselling, assisting,directing, and monitoring. To illustrate the paradigm, referenceis made to an alcohol education course developed for offendersin trouble through drink. The efficacy of the alcohol projectand the non-punitive paradigm is demonstrated by the resultsreported from a three year evaluation study covering 152 offenders.The article concludes with an affirmation of the disciplinedbut non-punitive character of current probation work and arguesthat, to successfully protect the public and reintegrate offendersinto the community, the probation officer's employment of establishedsocial work knowledge, skills, and values is a strength nota weakness.     

The psychosocial needs of the Chinese elderly

Changing Chinese family patterns caused by immigration have contributed to the breakdown of traditional community and familial control in Chinese-American families. As a result, the Chinese-American elderly are faced with unique psychosocial problems that workers must consider when providing services to this population.     

Political confrontation over fiscal processes: The impact of the U.S. Congressional Budget Act

In July 1974 the U.S. Congressional Budget Act was signed into law. This legislation was the result of a heavily fought political confrontation between President Nixon and Congress over who controlled the Federal budget. In addition to the issue of control, the Act was prompted by dissatisfaction with the procedures used by Congress to determine Federal receipts and expenditures. The purpose of this paper is to assess the impact this legislation had on the U.S. economy in its early years.The first section of the paper sets up a simple modeling framework. The model is specified so as to illustrate how a change in the budget process resulting from the Congressional Budget Act could potentially produce changes in the level of total output. This section also explains the derivation of a tax and expenditure series used in the model's empirical testing. The second section addresses some of the theoretical issues, and presents the results of simulations based on the Chase, Wharton, and Data Resources econometric models. Broad conclusions are gathered in the final section.     

试论颓废的现代性

颓废,作为19世纪文化艺术中的一个重要主题,从一个侧面,反映了西方资本主义理性主义暴政下的现代文化危机。它是一种艺术风格,也是一种生活姿态。它是艺术家借以逃避现代生活的矛盾、痛苦和精神荒芜的解救之道,客观上体现了艺术家在现代性语境中对抗资产阶级理性主义的审美立场。无论是作为一种美学理想,还是作为一种文化样态,颓废概念都无法回避其现代性的实质。     

Reconsidering the Marielito Legacy: Race/Ethnicity,Nativity, and Homicide Motives*

Objective. This article investigates how race/ethnicity is associated with specific types of violent crime such as killings between intimates, robbery homicide, or drug‐related killings. We extend the study of the role of race and ethnicity for violence by examining five ethnic/immigrant groups, including the Mariel Cubans—a group singled out by many as particularly drug‐crime‐prone. Methods. Using 1980 through 1990 homicide data for the City of Miami, we use multinomial logistic regression to examine the association between race/ethnicity, nativity, and several types of homicide motives. Results. Contrary to popular expectations, ethnicity and immigration status rarely play a role in the types of homicide involvement of victims or violators. Incident characteristics, such as multiple offenders, or gender and age, were consistently more important influences in shaping homicide circumstances. Conclusions. The analyses revealed few significant relationships between immigration status and homicide motives, suggesting that immigrant groups like the Marielitos have more in common with native groups' experiences of criminal violence than is commonly assumed.     

Understanding the Relationship Between Egalitarianism and Affective Bias: Avenues to Reducing Prejudice Among Adolescents

In an era during which affirmative action in education is in jeopardy, it is important to understand how the ideologies of high-status ethnic group members maintain (or reduce) social inequality. We examine the extent to which the relationship between egalitarianism and prejudice among European American and Asian American adolescents can be explained by outgroup orientation (i.e., how much one values interacting with members of other ethnic groups) and strength of identification with one's ethnic group. Using structural equation modeling, we tested whether these two variables mediate the relationship between egalitarianism and intergroup prejudice. Results revealed that outgroup orientation was a mediator, but ethnic identity was not. Implications for mutual acculturation theory, prejudice-reduction programs, and affirmative action in education are discussed.
