HIV Seroprevalence and Clinical Characteristics of Severe Inpatient Mentally III Homeless

Two related studies were carried out at a state psychiatric center unit designed for the long-term hospitalization of homeless mentally ill people removed from the streets of New York City and taken to hospitals for psychiatric treatment. The first study, a charl review of 102 patients, documented high rates of severe psychiatric illness, alcohol and other substance use, and untreated medical problems. Patient histories showed significant social disadvantages, including high rates of criminal activity and inability to complete high school or establish long-term relationships. Our second study anonymously tested 87 patients between the ages of 18 and 59 for the presence of HIV antibodies. An overall seroprevalence rate of 5.8% is reported. Men and women in this population are likely to have similar rates of HIV infection. Being young, and Black, or Hispanic appears to be associated with increased risk. This disenfranchised population urgently needs a broad array of social, medical and psychiatric selVices. Assertive community outreach programs are necessary to assure delivery of services to this population.     

Regional development —Alternatives for New England

In this paper the author examines the problems and opportunities of regional development in the economically mature north-eastern region of the United States. He argues that the most direct path to balanced growth is more planning. However, while the need is clear, society is quite opposed to any intervention into the market mechanism. Nonetheless the author argues, for more state and local planning in order to stimulate the market economy.

Leadership and culture in the Welsh Assembly: investigating path-dependency

This study of the developing Welsh Assembly (WA) provides a unique opportunity to comprehend how the values and public statements of a democratic institution's initial and ongoing leadership develop its structure and culture. We track the evolution of a new democratic institution and investigate relationships between leadership, path-dependency and cultural development. In this paper, Welsh Assembly Member (AM) leadership is analysed in relation to sources of path-dependency in the WA. Two sets of interviews and surveys provide AM perspectives of the Assembly in relation to the evolving leadership capability and institutional culture.     

Use of a case study in sequencing/scheduling research

This paper describes a study of an industrial sequencing/scheduling problem. The study contains the definition of the problem, data requirements and examination of solution technique. Definition of the problem is discussed from the aspect of uniqueness of the specific system. Discussion of data requirements includes availability and accuracy, while examination of solution technique considers limitation of time, computer capacity, etc., as well as the possibility of imbedding available algorithms into the solution procedure. Conclusions are presented relative to the use of the case study approach in sequencing/scheduling research.     

Who “They” Are Matters: Immigrant Stereotypes and Assessments of the Impact of Immigration

We investigate the relationship between stereotypes of immigrants and assessments of the impact of immigration on U.S. society. Our analysis exploits a split‐ballot survey of registered voters in Ohio, who were asked to evaluate both the characteristics of one of four randomly assigned immigrant groups and perceived impacts of immigration. We find that associations between impact assessments and stereotypes of Middle Eastern, Asian, and European immigrants are weak and fully attenuated by control covariates. By contrast, this relationship for Latin American immigrants is strong and robust to controls, particularly in the areas of unemployment, schools, and crime. Our findings suggest that public views of the impacts of immigration are strongly connected to beliefs about the traits of Latin American immigrants in particular.     

Bootstrap estimation of actual significance levels for tests based on estimated nuisance parameters

Often for a non-regular parametric hypothesis, a tractable test statistic involves a nuisance parameter. A common practice is to replace the unknown nuisance parameter by its estimator. The validality of such a replacement can only be justified for an infinite sample in the sense that under appropriate conditions the asymptotic distribution of the statistic under the null hypothesis is unchanged when the nuisance parameter is replaced by its estimator (Crowder M.J. 1990. Biometrika 77: 499–506). We propose a bootstrap method to calibrate the error incurred in the significance level, for finite samples, due to the replacement. Further, we have proved that the bootstrap method provides a more accurate estimator for the unknown actual significance level than the nominal level. Simulations demonstrate the proposed methodology.

A multilevel study of transformational leadership,identification, and follower outcomes

Using a sample from a large diversified company, this study examines the influence processes of transformational leadership (TFL) at both the individual and group levels concurrently and explores cross-level relationships. Results showed that, at the individual level, followers' personal identification with the leader mediated the effects of individual-focused TFL behavior on individual performance and empowerment. At the group level, group identification mediated the effect of group-focused TFL behavior on collective efficacy. Results also supported two cross-level effects from the group level to the individual level. The paper addresses the implications for leaders of motivating individuals and teams, at the same time.
