What Do We Know About Making Risk Comparisons?

The risks of unfamiliar technologies are often evaluated by comparing them with the risks of more familiar ones. Such risk comparisons have been criticized for neglecting critical dimensions of risky decisions. In a guide written for the Chemical Manufacturers Association, Covello et al. (¹) have summarized these critiques and developed a taxonomy that characterizes possible risk comparisons in terms of their acceptability (or objectionableness). We asked four diverse groups of subjects to judge the acceptability of 14 statements produced by Covello et al. as examples of their categories. We found no correlation between the judgments of acceptability produced by our subjects and those predicted by Covello et al. .     

Conditional methodology for individual case history data

Summary.  Key ecological studies involve the regular censusing of populations of wild animals, resulting in individual case history data which record when marked individuals are seen alive and/or found dead. We show how current conditional methods of analysing case history data may be biased. We then show how a correction can be applied, making use of results from a mark–recovery–recapture analysis. This allows a simple investigation of the effect of time-varying individual covariates such as weight that often contain missing values. The work is motivated and illustrated by the study of Soay sheep in the St Kilda archipelago.     

Mejor Sola Que Mal Acompañada: Strengths and Challenges of Mexican-Origin Mothers Parenting Alone

Marriage is often viewed as central to family stability and health, and problem-saturated discourses about single parenting have failed to address the advantages of parenting alone. Heuristic methodology was used to examine the meanings and experiences of Latinas parenting alone. This study reflects the lived experiences of 20 Mexican-origin women who participated in a 1- to 2-hour, in-depth, semistructured interview. Data are presented by three exemplary portraits and five core consistencies embedded in a composite depiction. Overall, although parenting alone was challenging, it was considered beneficial and preferable, especially when the child's father's influence was problematic or detrimental to the family's well-being. Chicana feminism and an intersectionality lens is used to interpret findings. Implications for research and intervention are also discussed.
