Evaluation of a Media Training Workshop for Nutrition Students and Trainees in Nova Scotia.

Gaps in communication training have been identified in Canadian and international academic and practicum dietetics programs. A workshop was developed to pilot supplementary media training to nutrition students/trainees studying in Nova Scotia. Students, interns, and faculty from two universities participated in the workshop. Data on perceived learning, media knowledge/skill use, and workshop feedback were collected immediately post-workshop using a mixed-form questionnaire. A modified questionnaire was administered eight months post-workshop to obtain information on utility of the perceived acquired knowledge/skills. Closed-ended responses underwent descriptive analysis, while open-ended responses underwent thematic analysis. Twenty-eight participants completed the questionnaire post-workshop, and six completed it at follow-up. All participants rated the workshop positively (7-point Likert scale) and reported learning something new (perceived). Perceived learning emphasized general media knowledge/skills and communication skills. Follow-up data suggested participants had applied perceived media knowledge/skills in message development and media and job interviews. These data suggest that nutrition students/trainees may benefit from supplementary communications and media training and provide a stimulus for ongoing curriculum review and discussion.

Pathogen exposure reduces sexual dimorphism in a host's upper thermal limits.

The climate is warming at an unprecedented rate, pushing many species toward and beyond the upper temperatures at which they can survive. Global change is also leading to dramatic shifts in the distribution of pathogens. As a result, upper thermal limits and susceptibility to infection should be key determinants of whether populations continue to persist, or instead go extinct. Within a population, however, individuals vary in both their resistance to both heat stress and infection, and their contributions to vital growth rates. No more so is this true than for males and females. Each sex often varies in their response to pathogen exposure, thermal tolerances, and particularly their influence on population growth, owing to the higher parental investment that females typically make in their offspring. To date, the interplay between host sex, infection, and upper thermal limits has been neglected. Here, we explore the response of male and female Daphnia to bacterial infection and static heat stress. We find that female Daphnia, when uninfected, are much more resistant to static heat stress than males, but that infection negates any advantage that females are afforded. We discuss how the capacity of a population to cope with multiple stressors may be underestimated unless both sexes are considered simultaneously.

Pandemic Stories: Rhetorical Motifs in Journalists' Coverage of Biomedical Risk.

This paper argues that journalists' discursive actions in an outbreak context manifest in identifiable rhetorical motifs, which in turn influence the delivery of biomedical information by the media in such a context. Via a critical approach grounded in rhetorical theory, I identified three distinct rhetorical motifs influencing the reportage of health information in the early days of the H1N1 outbreak. A public-health motif was exhibited in texts featuring a particular health official and offering the statements of such an official as a mechanism of reassurance. A concealment-of-information motif was exhibited in texts emphasizing the importance of the transparency of health officials, and in texts demonstrating ambivalence about information provided by socially-sanctioned sources. Finally, in texts mythologizing the outbreak to the exclusion of other functions of the text (e.g., conveying who is at risk, protective behaviours, symptoms), I identified a pandemic motif. Each motif differs in the conclusions it offers to audiences seeking to gauge relative levels of risk, and to receive information about protective behaviours. I suggest that one means of interpreting the manifestation of distinct rhetorical motifs in the context of a high-risk health threat is the certainty that this context alters moral responsibilities, consequently influencing the manifestation of narrative role.
