The Effects of the Culturally Tailored Narratives on COVID-19 Vaccine Confidence Among Hispanics: A Randomized Online Experiment.

Guided by the health belief model (HBM), cultural sensitivity approach, and the theory of situated cognition, this study compares the effects of culturally tailored narratives and generic narratives on the COVID-19 vaccine confidence among Hispanics. It also examines an array of cognitive responses (perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and perceived side effects) associated with the COVID-19 vaccine confidence, and the interaction of these cognitive responses with the two narrative types of messaging. The findings suggest that Hispanics exposed to culturally tailored narratives are more confident in the COVID-19 vaccine compared to Hispanics exposed to generic narratives. The study provides support for the HBM, as the perceived benefit was positively related to vaccine confidence, and the perceived barrier was negatively associated with vaccine confidence. Finally, vaccine confidence was the strongest among Hispanics who had high perceived susceptibility and were exposed to culturally tailored narratives.

Sink populations in carnivore management: cougar demography and immigration in a hunted population.

Carnivores are widely hunted for both sport and population control, especially where they conflict with human interests. It is widely believed that sport hunting is effective in reducing carnivore populations and related human-carnivore conflicts, while maintaining viable populations. However, the way in which carnivore populations respond to harvest can vary greatly depending on their social structure, reproductive strategies, and dispersal patterns. For example, hunted cougar (Puma concolor) populations have shown a great degree of resiliency. Although hunting cougars on a broad geographic scale (> 2000 km2) has reduced densities, hunting of smaller areas (i.e., game management units, < 1000 km2), could conceivably fail because of increased immigration from adjacent source areas. We monitored a heavily hunted population from 2001 to 2006 to test for the effects of hunting at a small scale (< 1000 km2) and to gauge whether population control was achieved (lambda < or = 1.0) or if hunting losses were negated by increased immigration allowing the population to remain stable or increase (lambda > or = 1.0). The observed growth rate of 1.00 was significantly higher than our predicted survival/fecundity growth rates (using a Leslie matrix) of 0.89 (deterministic) and 0.84 (stochastic), with the difference representing an 11-16% annual immigration rate. We observed no decline in density of the total population or the adult population, but a significant decrease in the average age of independent males. We found that the male component of the population was increasing (observed male population growth rate, lambda(OM) = 1.09), masking a decrease in the female component (lambda(OF) = 0.91). Our data support the compensatory immigration sink hypothesis; cougar removal in small game management areas (< 1000 km2) increased immigration and recruitment of younger animals from adjacent areas, resulting in little or no reduction in local cougar densities and a shift in population structure toward younger animals. Hunting in high-quality habitats may create an attractive sink, leading to misinterpretation of population trends and masking population declines in the sink and surrounding source areas.
