ABSTRACT
BACKGROUND: Past research shows that physicians experience high ill-being (i.e., work-life conflict, stress, burnout) but also high well-being (i.e., job satisfaction, engagement). OBJECTIVE: To shed light on how medical faculty's experiences of their job demands and job resources might differentially affect their ill-being and their well-being with special attention to the role that the work-life interface plays in these processes. METHODS: Qualitative thematic analysis was used to analyze interviews from 30 medical faculty (19 women, 11 men, average tenure 13.36 years) at a top research hospital in Canada. FINDINGS: Medical faculty's experiences of work-life conflict were severe. Faculty's job demands had coalescing (i.e., interactive) effects on their stress, work-life conflict, and exhaustion. Although supportive job resources (e.g., coworker support) helped to mitigate the negative effects of job demands, stimulating job resources (e.g., challenging work) contributed to greater work-life conflict, stress, and exhaustion. Thus, for these medical faculty job resources play a dual-role for work-life conflict. Moreover, although faculty experienced high emotional exhaustion, they did not experience the other components of burnout (i.e., reduced self-efficacy, and depersonalization). Some faculty engaged in cognitive reappraisal strategies to mitigate their experiences of work-life conflict and its harmful consequences. CONCLUSION: This study suggests that the precise nature and effects of job demands and job resources may be more complex than current research suggests. Hospital leadership should work to lessen unnecessary job demands, increase supportive job resources, recognize all aspects of job performance, and, given faculty's high levels of work engagement, encourage a climate that fosters work-life balance.
ABSTRACT
Tactile spatial acuity is enhanced in blindness, according to several studies, but the cause of this enhancement has been controversial. Two competing hypotheses are the tactile experience hypothesis (reliance on the sense of touch drives tactile-acuity enhancement) and the visual deprivation hypothesis (the absence of vision itself drives tactile-acuity enhancement). Here, we performed experiments to distinguish between these two hypotheses. We used force-controlled grating orientation tasks to compare the passive (finger stationary) tactile spatial acuity of 28 profoundly blind and 55 normally sighted humans on the index, middle, and ring fingers of each hand, and on the lips. The tactile experience hypothesis predicted that blind participants would outperform the sighted on the fingers, and that Braille reading would correlate with tactile acuity. The visual deprivation hypothesis predicted that blind participants would outperform the sighted on fingers and lips. Consistent with the tactile experience hypothesis, the blind significantly outperformed the sighted on all fingers, but not on the lips. Additionally, among blind participants, proficient Braille readers on their preferred reading index finger outperformed nonreaders. Finally, proficient Braille readers performed better with their preferred reading index finger than with the opposite index finger, and their acuity on the preferred reading finger correlated with their weekly reading time. These results clearly implicate reliance on the sense of touch as the trigger for tactile spatial acuity enhancement in the blind, and suggest the action of underlying experience-dependent neural mechanisms such as somatosensory and/or cross-modal cortical plasticity.
