Barriers to accessing HIV and sexual health services among gay men in Tasmania,Australia

We examined barriers to accessing HIV and sexual health services among gay and bisexual men (GBM) in Tasmania, Australia, using in-depth interviews. Most participants were satisfied with the care they had received at public sexual health services. Barriers included the limited number of services, concerns about anonymity and privacy in small communities, difficulties accessing services via a general practitioner, and perceived stigma and discrimination. Improving the accessibility and availability of HIV and sexual health services in Tasmania is crucial to promote the engagement of GBM, which could be achieved via combined efforts of government services and community organizations.     

HMO marketing: the Cadillac and the Chevy.

The author's bias and goal is to create an effective group practice model. Managed care will play an important role in this model. This article is designed to examine the role of an HMO in this model and to provide a framework for examining the HMO-group practice relationship. The bottom line question : Are HMOs the most effective group practice vehicle for delivering managed care?     

Testing for heteroscedasticity in regression models

A new test for heteroscedasticity in regression models is presented based on the Goldfeld-Quandt methodology. Its appeal derives from the fact that no further regressions are required, enabling widespread use across all types of regression models. The distribution of the test is computed using the Imhof method and its power is assessed by performing a Monte Carlo simulation. We compare our results with those of Griffiths & Surekha (1986) and show that our test is more powerful than the wide range of tests they examined. We introduce an estimation procedure using a neural network to correct the heteroscedastic disturbances.     

The need for new statistical legislation for the UK

Summary. The paper is written to inform public discussion on whether or not statistical legislation for the UK is needed and, if so, on its nature and content. A brief account of the background to the current position is given. The Government's stated intention is to create an 'independent statistical service' and a discussion of the meaning of independence in the context of official stat- istics and governance arrangements is provided. Recent international experience is described and the Statistics Acts of some other countries are used to distil the key features of Statistics Acts in other countries. The arguments for and against possible legislation are described. Whether or not a Statistics Act is desirable for the UK depends strongly on the legislation being well framed. There are several key issues on which Parliament would need to develop an informed view and these are set out towards the end of the paper.     

Perception of Teacher Sexual Misconduct by Age of Student

ABSTRACT

This study explored whether student age influenced perceptions of teacher sexual misconduct. Participants (300 undergraduates) read scenarios depicting teacher sexual misconduct in which the student's age was varied (9, 12, 15), and then answered questions about their perceptions. Data were analyzed with 2 (respondent gender) × 2 (cross-gender dyads) × 3 (student age) MANOVAs. Experiences involving the youngest student were viewed as the most abusive, followed by the 12-year-old, and the 15-year-old. Gender differences were evident, with women viewing the experiences more negatively. Scenarios involving a male teacher/female student were viewed more negatively than a female teacher/male student dyad. These findings illustrate the importance of educating students and school personnel about teacher sexual misconduct.     

Taiwan and ROC: A critical analysis of President Chen Shui-bien's construction of Taiwan identity in national speeches

Names used to address Taiwan – such as taiwan and zhonghuamingguo (Republic of China [ROC]) – are symbols defining Taiwan's political realities, each with their own unique historical significance. Since his election in 2000, Taiwan's president Chen Shui-bien has had to alternate between taiwan and ROC to strike a balance among conflicting ideas about Taiwan's national identity. The act is grounded in complex political discourse dictating that Taiwan must not be seen as separate from the sinic world and simultaneously to respond to steadily rising Taiwanese consciousness. Facing intercessions by the United States and China, as well as ever-present domestic clashes, rhetorical exigency requires the president to fashion unique political discourse concerning what Taiwan is and ought to be. This study explores how these names and related expressions are used in Chen's public addresses to the nation during his two-term tenure from 2000 to 2008, and how their development reflects the struggle over Taiwan's national identity.     

Bayesian Interval Estimation for Predictive Values from Case-Control Studies

Positive predictive and negative predictive values (PPV and NPV) are often used to assess the accuracy of binary diagnostic tests. Unlike sensitivity and specificity, PPV and NPV are functions of the accuracy of the test and the overall prevalence of the disease in the population. In many studies of performance of estimators of PPV and NPV the population prevalence is assumed known. We allow for uncertainty in the estimate of the population prevalence and via simulation explore the impact of deviations from the assumed value.     

‘The terrorist in my home’: teenagers' violence towards parents – constructions of parent experiences in public online message boards

Teenagers' violence towards parents is a hidden and underexplored problem, particularly within the UK, and the stigma attached to such experiences makes research access difficult. In this study, two online message boards which featured parents' posted accounts of their teenagers' violence towards them were analysed. Using discourse analysis, three consistent discursive themes were identified: the emotional terrain of such experiences, the psychologisation of the child‐as‐‘perpetrator’ and parental responses to these complex experiences. Overall, these three themes were weaved together to produce overarching narratives of powerlessness and loss of hope. The theoretical and practical implications of this analysis are discussed, including a consideration of how such online message boards enable and delimit parental agency.     

Effectiveness of the International Child Development Programme: Results from a randomized controlled trial

This study aimed to evaluate the effectiveness of the International Child Development Programme (ICDP), a group-based parenting programme used internationally and implemented nationally in Norway. We used a cluster randomized controlled trial in which 81 groups were randomly assigned to either the intervention or waitlist control condition after the baseline data collection. A total of 590 parents completed at least one of three questionnaires (administrated before and after ICDP and 4 months after completing the intervention). Primary outcomes included parental self-efficacy, parental emotion sensitivity and positive involvement with their child. Secondary outcomes included parents' perceptions of their relationship with the child, child-rearing conflicts and the child's psychosocial health. We found significant effects favouring the intervention arm following the intervention and at follow-up on two primary outcomes (parental self-efficacy and emotion sensitivity). For the secondary outcomes, we found a significant reduction in child-rearing conflict at the 4-month follow-up, increased closeness to the child, reduced child internalizing difficulties and increased prosocial behaviour immediately following the intervention. However, ICDP seems to have limited effects on parent-reported changes in children. We conclude that ICDP as a universal preventive programme offered to parents in groups can be effective in strengthening parental self-efficacy and improving parental emotion sensitivity.     

THE COVARIANCE ANALYSIS OF SOME CENSORED SURVIVAL DATA FROM A LARGE SCALE STUDY OF MELANOMA

Regression models of the proportional hazard type are applied to investigate the effect of certain covariates on the survival function of some cancer patients. The censored survival data for these patients were taken from a survey conducted by the Queensland Melanoma Project through which there are available histories of all malignant melanoma cases in Queensland for the period 1963–1969; follow-up data on these cases were considered up to mid-1976. One of the results of the survival analysis shows that the well-known empirical observation that women have a better prognosis than men can be explained by the existence of a significant interaction between sex and the anatomical site of the lesion.
