Evaluating characteristics of community riparian awareness program interactions.

As part of its mandate to evaluate and monitor program delivery, the Alberta Riparian Habitat Management Society (Cows and Fish) has commissioned independent evaluations to examine the effectiveness and applicability of the community-based riparian awareness and management program. The society's aim is to improve the understanding of landscape function, to better enable landowners and managers to make management decisions. The staff interaction evaluation examined staff ability to deliver certain valued characteristics, and identified whether the program and staff increased awareness and management action. Respondents rated staff highly on all characteristics. Landowners that participated in riparian health programming as part of community/watershed groups were 19% more likely to have learned new information and 21% more likely to implement management change than those that were not part of a group. Repeat interactions are critical to learning new information and influencing management. All those with frequent interactions had learned new information, compared to only 70% of those with very little interaction. A diverse array of interactions led respondents to alter their management, indicating the need for a wide variety of extension tools and activities. The results strongly support the need for a community-based approach in resource management and awareness activities, which enables repeat, ongoing and diverse interactions with extension staff.

Pertussis: herd immunity and vaccination coverage in St Lucia.

In a single complete epidemic in St Lucia, an island too small to support constant clinical pertussis, the pertussis case rates in small communities (villages and small towns) with differing levels of vaccination coverage of young children were compared. The association between greater vaccination coverage and greater herd immunity was clear, despite the imperfect protection given to individuals. An analysis in terms of population dynamics is evidence against the theory that endemic subclinical pertussis maintains transmission in a highly vaccinated population. We suggest that with a homogeneous vaccination coverage of 80% of 2-year-old children pertussis might be eradicated from the island, and that this is a practicable experiment.

Overview of randomized clinical trials of lipid intervention for atherosclerotic cardiovascular disease.

This paper is a review of the scientific and economic (when possible) impact of 15 randomized clinical trials of lipid intervention for atherosclerotic cardiovascular disease. No effort has been made to be all-inclusive and certain smaller and first generation studies have been omitted. No effort has been made to offer detailed analyses of protocols; we have limited discussion to summaries of the salient features of each study presented. After stating the data, we introduce certain reflections and raise some of the more obvious questions that emerge.
