Short-run characteristics of samples drawn by random walks

An alternative to using acceptance-rejection methods to generate a sample of points distributed uniformly over a region is to employ a random walk over that region. The sequence of points generated by a random walk has been shown, under certain easily satisfied conditions, to be a realization of a vector-valued discrete parameter Markov process, and to have the uniform distribution as its limiting distribution. The purpose of this paper is to point out that even if the marginal distribution of each point is actually uniform, rather than merely being asymptotically uniform, small samples may exhibit nonuniform characteristics due to serial autocorrelation within the sample.     

Termination of Casework: The Student,Client and Field Instructor

This study of 65 supervisees and 64 supervisors addresses current issues in social work supervision through exploring various models of structure, authority, and teaching that were perceived to be in use. Significant differences in level of interaction, supervision and job satisfaction, and sense of accomplishment were found as the source of the supervisors' authority varied, but no differences occurred in variations of structure. Incongruence between supervisees' and supervisors' perceptions of actual and preferred structure, authority, conference frequency and initiation, and content in supervision demonstrates the need for exploration of autonomy in practice and control in supervision.     

A Survey of Online Practitioners: Implications for Education and Practice

In the last decade the helping professions have seen a growing interest in the provision of online counseling and therapeutic services for individuals. Like most fields of work, social work also has experienced a growth in the creative use of technology in various areas of professional work. Based on this growing interest and the need for such services and research on its efficacy, a study was conducted to learn from e-therapists across the United States on their experiences with this mode of service delivery. This paper elicits results from the online survey and provides recommendations to better serve our clients in the tech savvy world and future research endeavors. The main findings of this preliminary study include: (a) Many theoretical perspectives and models are being used to ground online practice, (b) e-therapists are beginning to use videoconferencing for online practice supplementing their face-to-face sessions, and (c) e-therapists believe that online interventions benefit their clients.     

Lesbian Health Care: Women's Experiences and the Role for Social Work

ABSTRACT

Lesbian patients and their families may be exposed to discriminatory practices in the health care system. This qualitative study of 57 Midwestern lesbian parents used open- and closed-ended questions to examine the experiences the respondents had with their primary and secondary health care providers. Four themes emerged from the data: systemic barriers to health care, coming out to providers, seeking lesbian, gay, bisexual, and transgender-friendly health care providers, and concern about mistreatment and prejudice within the health care system. Implications for service delivery, health care education, and directions in policy and research are explored.     

The Role of Procedural Justice in Public Personnel Management: Empirical Results from the Department of Defense

This article examines the relationship between federal employeeperceptions of procedural justice and work satisfaction rates,turnover intentions, and the degree to which employees trusttheir managers. As the federal government considers reformingthe civil service system, including changes to the proceduresused to discipline employees and resolve grievances, understandingthese relationships becomes particularly important. Analysisof Department of Defense data from the 2002 Federal Human CapitalSurvey indicates a significant, positive relationship betweenprocedural justice perceptions, satisfaction rates, and trustin management. Likewise, a significant and negative relationshipexists between procedural justice perceptions and turnover intentions.Interestingly, given similar levels of procedural justice perceptions,managers exhibit lower levels of satisfaction and trust andhigher turnover intentions. This study provides an importantbenchmark for Defense and other agencies that are redesigningpersonnel systems and serves as a caution against implementingsystems that employees may not view as either legitimate orjust.     

A new approach to default priors and robust bayes methodology

Following the developments in DasGupta et al. (2000), the authors propose and explore a new method for constructing proper default priors and a method for selecting a Bayes estimate from a family. Their results are based on asymptotic expansions of certain marginal correlations. For ease of exposition, most results are presented for location families and squared error loss only. The default prior methodology amounts, ultimately, to the minimization of Fisher information, and hence, Bickel's prior works out as the default prior if the location parameter is bounded. As for the selected Bayes estimate, it corresponds to ‘Gaussian tilting’ of an initial reference prior.     

INTEGRATING ECONOMIC DUALISM AND LABOR MARKET SEGMENTATION:

Although the U.S. economy of the early twenty-first century is vastly different from the U.S. economy prior to the 1970s, the nature of these economic changes and their impact on U.S. workers is unclear. This article claims that despite contemporary economic shifts, differential labor and employer power continues to segment the economy, and workers' position in the labor market continues to predict their rewards, beyond the effects of gender, race, and human capital. Drawing on segmented labor market and dual economy research, we propose a four-category model of the structural factors that influence variance in work-related rewards. We examine the distribution of jobs in each of four categories between 1974 and 2000 and observe that losses and gains across categories are unevenly distributed by race and gender. While white men have experienced the greatest declines in employment and earnings, they have maintained their absolute advantage over women and nonwhites. In multivariate analyses, we find that the structural position of employment continues to be a significant determinant of wages. Although women and racial minorities have experienced sizable increases in employment in primary labor market jobs in the core of the economy, both groups remain overrepresented in low-paying jobs. Moreover women, but not nonwhite men, consistently receive significantly fewer rewards for their labor in both low-paying and high-paying jobs. Our findings suggest that structural factors continue to influence earnings inequality, especially across race and gender lines.     

HIV seroprevalence and clinical characteristics of severe inpatient mentally Ill 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 chart 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 services. Assertive community outreach programs are necessary to assure delivery of services to this population.
