A call for the development of “good research practices” (GRP) guidelines

It is proposed that the scientific community develop and implement “Good Research Practices”; (GRP) guidelines in order to improve the quality of research, reduce the incidence of scientific misconduct, and save large sums of monies from being wasted.     

Recent Happenings in the Social Studies

This article details the “journey box” project process enacted by two elementary preservice teacher cohorts. Engaging in activities and projects that promote a sense of investment in not only consuming but producing historical narratives, preservice teachers potentially become interested in sharing this type of learning with their students.     

Hispanic Fertility,Religion and Religiousness in the U.S.

Is the higher fertility of Hispanics in the United States due to their religion and/or to their greater religiousness? Evidence from national survey data indicates no difference in fertility between Protestant and Catholic Hispanic women but Hispanics are more religious than non-Hispanics in terms of the perceived importance of religion in their personal lives. Religiousness is associated with higher fertility but Hispanic fertility is higher than non-Hispanic fertility regardless of religion or religiousness. Ethnic differences in education and income in turn are more important for fertility than the religious dimension.     

In Search of the Optimum Harvey Wallbanger Recipe via Mixture Experiment Techniques

A Harvey Wallbanger is an alcoholic drink composed of three ingredients: orange juice, vodka, and Galliano. One of the authors (Sahrmann), a connoisseur of the libation, was perplexed upon discovering that different bartender handbooks listed different recipes for the drink. Determined to shed some light on this irksome problem, he issued invitations for an evening workshop session (party) to former and current attendees of an experimental-design training course taught within his company. A mixture experiment was designed and data collected using the class participants. This article describes the experimental design and the analysis of the data. The results of the experiment indicate that reducing the proportion of vodka produces better-flavored drinks. The results of the experiment were not entirely conclusive, however, so recommendations are made for future experimentation.     

Locally optimal designs for the simple death process

We demonstrate the existence and uniqueness of optimal observation schedules for discrete observation of the simple death process. Optimality is framed in the sense of observing the process at times that maximise the Fisher information for the death rate. We examine the relationship of our designs with those obtained by other authors for the simple birth process. A number of interesting properties are uncovered. Practical considerations in the application of these designs in an experimental setting are investigated, and we examine the performance of some approximately optimal designs that are usually simpler to implement. We will show that our optimal designs are highly robust to mis-specification of the death rate.     

Impact of Empowerment Training on the Professional Work of Family Peer Advocates

A pilot study using a prospective design examined the impact of a collaboratively developed training model, called the Parent Empowerment Program (PEP), for professionally-employed family peer advocates who work with caregivers of children with mental health needs. This training used a combination of didactic, practice exercises, and group discussion. It targeted specific mental health knowledge content and collaborative skills to facilitate the work of family peer advocates in empowering caregivers. Co-delivered by a family peer advocate and clinician, the training consisted of a 40-hour face-to-face training, followed by six monthly face-to-face booster sessions. A total of 15 advocates participated in assessments conducted at baseline and post-training. This group of experienced family peer advocates showed no significant increase in knowledge about mental health content, but post-training assessments indicated increased collaborative skills and mental health services self-efficacy. This initial evaluation has implications for expanding training and support for the emergent workforce of professionally-employed family peer advocates in children's mental health.     

GENDER AND THE HEALTH BENEFITS OF EDUCATION

Does education improve health more for one sex than the other? We develop a theory of resource substitution which implies that education improves health more for women than men. Data from a 1995 survey of U.S. adults with follow‐ups in 1998 and 2001 support the hypothesis. Physical impairment decreases more for women than for men as the level of education increases. The gender gap in impairment essentially disappears among people with a college degree. Latent growth SEM vectors also show that among the college educated, men's and women's life course patterns of physical impairment do not differ significantly.
