Mental Models in Risk Assessment: Informing People About Drugs

One way to communicate about the risks of drugs is through the use of package inserts. The problems associated with this medium of informing patients have been investigated by several researchers who found that people require information about drugs they are using, including extensive risk information, and that they are willing to take this information into account in their usage of drugs. But empirical results also show that people easily misinterpret the information given. A conceptual framework is proposed that might be used for better understanding the cognitive processes involved in such a type of risk assessment and communication. It is based on the idea that people develop, through experience, a mental model of how a drug works, which effects it might produce, that contraindications have to be considered, etc. This mental model is "run" when a specific package insert has been read and a specific question arises such as, for example, whether certain symptoms can be explained as normal or whether they require special attention and action. We argue that the mental model approach offers a useful perspective for examining how people understand package inserts, and consequently for improving their content and design. The approach promises to be equally useful for other aspects of risk analysis that are dependent upon human judgment and decision making, e.g., threat diagnosis and human reliability analysis.     

Safe Schools Policy for LGBTQ Students and commentaries

Two proposed U.S. federal laws would provide explicit protection for lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) students in public schools. These federal laws follow actions by many states and school districts to define and implement laws or policies to protect the safety of LGBTQ students in schools. Research during the past decade has shown that LGBTQ youth are a vulnerable population, and that the negative school experiences of LGBTQ students often contribute to their vulnerability. This Social Policy Report reviews research relevant to these federal, state, and local laws and policies. Research on sexual orientation/identity development is reviewed, with attention to the growing numbers of youth that “come out” or disclose their LGBTQ identities to others during their school-age years. Schools are often hostile environments for LGBTQ students; this evidence is considered along with research on the consequences for compromised achievement and emotional and behavioral health. We then review strategies in education policy and practice that are associated with well-being for LGBTQ (and all) students.     

Assessing Speech Discrimination in Individual Infants

Assessing speech discrimination skills in individual infants from clinical populations (e.g., infants with hearing impairment) has important diagnostic value. However, most infant speech discrimination paradigms have been designed to test group effects rather than individual differences. Other procedures suffer from high attrition rates. In this study, we developed 4 variants of the Visual Habituation Procedure (VHP) and assessed their robustness in detecting individual 9‐month‐old infants' ability to discriminate highly contrastive nonwords. In each variant, infants were first habituated to audiovisual repetitions of a nonword (seepug) before entering the test phase. The test phase in Experiment 1 (extended variant) consisted of 7 old trials (seepug) and 7 novel trials (boodup) in alternating order. In Experiment 2, we tested 3 novel variants that incorporated methodological features of other behavioral paradigms. For the oddity variant, only 4 novel trials and 10 old trials were used. The stimulus alternation variant was identical to the extended variant except that novel trials were replaced with “alternating” trials—trials that contained repetitions of both the old and novel nonwords. The hybrid variant incorporated elements from both the oddity and the stimulus alternation variants. The hybrid variant proved to be the most successful in detecting statistically significant discrimination in individual infants (8 out of 10), suggesting that both the oddity and the stimulus alternation features contribute to providing a robust methodology for assessing discrimination in individual infants. In Experiment 3, we found that the hybrid variant had good test‐retest reliability. Implications of these results for future infant speech perception work with clinical populations are discussed.     

Can oil-led growth and structural change go hand in hand in Ghana?

Unlike in Asia, the manufacturing sector has not (yet) become a driver of structural change in Africa. One common explanation is that the natural resource-focus of many African economies leads to Dutch disease effects. To test this argument for the case of newly found oil in Ghana we develop a multi-sector intertemporal general equilibrium model with endogenous savings and investment behavior. Results show that in addition to the well-known short-term Dutch disease effects, long-term structural effects can indeed impede Asian-style economic transformation in Ghana (and other resource rich countries). We also demonstrate how oil wealth may go hand in hand with structural change in the future.     

A Survey of Accommodation Needs,Capabilities and Desires of Handicapped People

A survey of the accommodation needs of eighty-three handicapped people in the Sydney area is described. Results suggest that present accommodation is more a function of opportunity and finance than of preferred choice, and that there is a demand among disabled people of all ages for more independent housing.     

Incarcerated Dutch juvenile sex offenders compared with non-sex offenders

There is some debate about whether or not sex offenders are similar to non-sex offenders with regard to family background (parental characteristics), personality, and psychopathology. The central aim of this study focused on the comparison of juvenile sex offenders and non-sex offenders. The sample consisted of incarcerated juvenile male sex (n = 30) and non-sex (n = 368) offenders. It appeared that sex offenders resembled non-sex offenders with respect to most of the offender and parental characteristics. Results demonstrated some differences between both groups, while the majority of characteristics were similar. Limitations of the study are discussed, especially the low number of sex offenders, followed by suggestions for further research.
