The intersection of race, poverty and risk: understanding the decision to provide services to clients and to remove children

Studies have found that certain racial groups, particularly the children of African American families, are placed in foster care at a higher rate than children of other races. These families are also sometimes found to be afforded fewer services that might prevent these removals, relative to families of other races. It is unclear why this is so. Poverty has been suspected, and sometimes found, to be the primary cause of the disparity. Lacking in some of these analyses, however, was how risk of future abuse/neglect to the child entered into the decisions and particularly, how assumptions about race, poverty, and risk are factored into the decision-making process. It is important to understand this process if we are to find a way to correct it. The current study addresses this process.     

“Limiting Birth”: Birth Control in Colonial Korea (1910–1945)

This article examines birth control as practice and discourse in 1920s and 1930s Korea under Japanese colonial rule and explores links with family planning and reproductive practices in post-1945 South Korea. The control of women’s reproduction held critical implications for meanings of domesticity, marriage, sexual relations, and new womanhood. While a woman-centered position did emerge regarding birth control, the parameters of the discourse, concerns of gynecology, and the material culture of birth control ultimately tied the bodies and health of women to their biological and social roles as mothers.

Over-the-counter medication and herbal or dietary supplement use in college: dose frequency and relationship to self-reported distress

OBJECTIVE: A growing number of researchers have examined the use of over-the-counter (OTC) medications and herbal or dietary supplements among college students. There is concern about the efficacy and safety of these products, particularly because students appear to use them at a higher rate than does the general public. PARTICIPANTS AND METHODS: The authors administered surveys to college students (N = 201) to assess the frequency of use in the past week. RESULTS: A substantial percentage reported using OTC medications (74.1%), herbal or dietary supplements (70.6%), or both concurrently (61.2%). Dose frequency of OTC medications was the best predictor of self-reported emotional distress in the past week. Higher doses of products containing pseudoephedrine or valerian were associated with self-reported anxiety. CONCLUSIONS: These data further reflect an increasing trend toward self-medication among college students. Investigators must conduct reliability and validity studies to evaluate the clinical utility of the measurement tool developed in this study.     

High-risk sexual behavior among students of a minority-serving university in a community with a high HIV/AIDS prevalence

OBJECTIVE: The authors used a stratified cluster sampling design to inform campus sexually transmitted diseases prevention programs. PARTICIPANTS AND METHODS: They conducted a cross-sectional study of students (N = 1,130) at a large, urban, minority-serving university in South Florida using the 2004 National College Health Assessment Survey instrument. RESULTS: Of the 1,130 participants, 14.0% reported risky sexual behavior (having more than 1 sexual partner in 1 year and not using a condom the last time they had vaginal intercourse), and 11.9% reported consistent risky sexual behavior (having more than 1 partner in 1 year and not using condoms most or all of the time during the past 30 days). In multivariable analysis, past-month alcohol use had the strongest independent association with both risky and consistent risky sexual behavior. Illicit drug use was marginally significant in both models. CONCLUSIONS: Administrators should address the use of alcohol and other drugs on campus in planning interventions to promote safe sexual behavior.     

Bayesian analysis for monotone hazard ratio

We propose a Bayesian approach for estimating the hazard functions under the constraint of a monotone hazard ratio. We construct a model for the monotone hazard ratio utilizing the Cox’s proportional hazards model with a monotone time-dependent coefficient. To reduce computational complexity, we use a signed gamma process prior for the time-dependent coefficient and the Bayesian bootstrap prior for the baseline hazard function. We develope an efficient MCMC algorithm and illustrate the proposed method on simulated and real data sets.     

Graphical displays for clarifying how allocation ratio affects total sample size for the two sample logrank test

For time‐to‐event data, the power of the two sample logrank test for the comparison of two treatment groups can be greatly influenced by the ratio of the number of patients in each of the treatment groups. Despite the possible loss of power, unequal allocations may be of interest due to a need to collect more data on one of the groups or to considerations related to the acceptability of the treatments to patients. Investigators pursuing such designs may be interested in the cost of the unbalanced design relative to a balanced design with respect to the total number of patients required for the study. We present graphical displays to illustrate the sample size adjustment factor, or ratio of the sample size required by an unequal allocation compared to the sample size required by a balanced allocation, for various survival rates, treatment hazards ratios, and sample size allocation ratios. These graphical displays conveniently summarize information in the literature and provide a useful tool for planning sample sizes for the two sample logrank test.

Expectation gaps between stakeholders and web-based corporate public relations efforts: Focusing on Fortune 500 corporate web sites

This study investigates how Fortune 500 corporations use corporate-focused web site public relations efforts to prioritize different stakeholders while trying to meet the expectations of each stakeholder. The study found that shareholder needs are most often addressed by the corporations followed by consumers, community members, government agencies, and activists. The results of the study suggest there are expectation gaps between stakeholders and web-based corporate public relations efforts. The study also found differences in the way various industries target stakeholders with the exception of shareholders.
