Work stress is endemic among direct care workers (DCWs) who serve people
with intellectual and developmental disabilities. Social resources, such as work
social support, and personal resources, such as an internal locus of control,
may help DCWs perceive work overload and other work-related stressors as less
threatening and galvanize them to cope more effectively to prevent burnout.
However, little is known about what resources are effective for coping with what
types of work stress. Thus, we examined how work stress and social and personal
resources are associated with burnout for DCWs.
We conducted a survey of DCWs (n = 323) from five
community-based organizations that provide residential, vocational, and personal
care services for adults with intellectual and developmental disabilities.
Participants completed a self-administered survey about their perceptions of
work stress, work social support, locus of control, and burnout relative to
their daily work routine. We conducted multiple regression analysis to test both
the main and interaction effects of work stress and resources with respect to
burnout.
Work stress, specifically work overload, limited participation
decision-making, and client disability care was positively associated with
burnout (p < .001). The association between work social
support and burnout depended on the levels of work overload (p
< .05), and the association between locus of control and burnout depended
on the levels of work overload (p < .05) and
participation in decision-making (p < .05). Whether work
social support and locus of control make a difference depends on the kinds and
the levels of work stressors.
The findings underscore the importance of strong work-based social
support networks and stress management resources for DCWs.
Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily herbivorous mega-consumers that may migrate over hundreds to thousands of kilometers. Our dataset, the largest ever compiled for sea turtles, has 9690 growth increments from 30 sites from Bermuda to Uruguay from 1973 to 2015. Using generalized additive mixed models, we evaluated covariates that could affect growth rates; body size, diet, and year have significant effects on growth. Growth increases in early years until 1999, then declines by 26% to 2015. The temporal (year) effect is of particular interest because two carnivorous species of sea turtles-hawksbills, Eretmochelys imbricata, and loggerheads, Caretta caretta-exhibited similar significant declines in growth rates starting in 1997 in the West Atlantic, based on previous studies. These synchronous declines in productivity among three sea turtle species across a trophic spectrum provide strong evidence that an ecological regime shift (ERS) in the Atlantic is driving growth dynamics. The ERS resulted from a synergy of the 1997/1998 El Niño Southern Oscillation (ENSO)-the strongest on record-combined with an unprecedented warming rate over the last two to three decades. Further support is provided by the strong correlations between annualized mean growth rates of green turtles and both sea surface temperatures (SST) in the West Atlantic for years of declining growth rates (r = -.94) and the Multivariate ENSO Index (MEI) for all years (r = .74). Granger-causality analysis also supports the latter finding. We discuss multiple stressors that could reinforce and prolong the effect of the ERS. This study demonstrates the importance of region-wide collaborations.
Interventions aimed at increasing physical activity participation among obese African American women with mobility disabilities should start with increasing their awareness/knowledge on where and how to exercise. Other reported barriers (e.g., cost, transportation, finding an accessible facility, health concerns, pain) may not be as critical to alter/remove as identifying where participants can exercise (i.e., home, outdoors, gym) and providing them with a variety of routines that can be performed safely in their desired setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
