RESUMO
According to Kirk & Rhodes (2011), Nooijen et al. (2018), and Saridi et al. (2019), the motivators and barriers to exercise are influenced by one's occupation, especially among those in the healthcare field. We sought to examine the barriers and motivators to physical activity that are distinctive to clinicians. Community hospital clinicians were surveyed regarding motivators and barriers to exercise that they experience, their burnout levels as described by an adaptation of the Mini-Z single item burnout scale, and average weekly exercise habits. The top barriers and motivators were then correlated to burnout levels, levels of physical activity, and demographics. We received 64 total responses from clinicians. The overall average level of burnout was 2.37 and the median level was 2. Approximately 38% of clinicians reported adhering to American Heart Association (AHA) guidelines of 150 minutes of exercise per week, while 33% of clinicians exercise <75 minutes per week. The top general motivator was for one's own well-being and the top clinician-related motivator was reducing stress. The top two barriers to exercise were COVID-19 concerns at an indoor exercise facility and a lack of time. Higher average levels of burnout were experienced by those who marked being too stressed or too burnt out as barriers to exercise. Because of clinicians' roles in propagating healthy practices in their patients from their own habits, wellness programs should be aimed at capitalizing motivators to combat barriers that this group distinctively experiences. Efforts to improve physical and mental wellness among clinicians will translate into better provider and patient health outcomes.
RESUMO
Signals of selection on quantitative traits can be detected by the comparison between the genetic differentiation of molecular (neutral) markers and quantitative traits, by multivariate extensions of the same model and by the observation of the additive covariance among relatives. We studied, by three different tests, signals of occurrence of selection in Prosopis alba populations over 15 quantitative traits: three economically important life history traits: height, basal diameter and biomass, 11 leaf morphology traits that may be related with heat-tolerance and physiological responses and spine length that is very important from silvicultural purposes. We analyzed 172 G1-generation trees growing in a common garden belonging to 32 open pollinated families from eight sampling sites in Argentina. The multivariate phenotypes differ significantly among origins, and the highest differentiation corresponded to foliar traits. Molecular genetic markers (SSR) exhibited significant differentiation and allowed us to provide convincing evidence that natural selection is responsible for the patterns of morphological differentiation. The heterogeneous selection over phenotypic traits observed suggested different optima in each population and has important implications for gene resource management. The results suggest that the adaptive significance of traits should be considered together with population provenance in breeding program as a crucial point prior to any selecting program, especially in Prosopis where the first steps are under development.
