Racial diversity in the U.S. workforce is increasing, and many organizations are more racially diverse than ever before. Racial minority employees experience the ecosystem of work demands and resources differently to white employees; including perceiving higher demands, lower control and support, greater stress and psychological strain, and less well-being. However, there remains little research on how relationships between these work characteristics and well-being and strain, and interrelationships differ across more racially diverse versus homogeneous (e.g., predominantly white) workplaces. This limits understanding of optimal job redesign practices as workplaces continue to become more racially diverse. Through the lens of the job demands, control, support (JDC[S]), and the job demands-resources (JD-R) frameworks, we build on previous meta-analyses by examining workplace racial composition as a moderator of demand-resource relationships with well-being and strain, and interrelationships, in 63 studies of U.S. workers (N(Individuals) = 93,974). Our findings show several moderation effects. For example, as the proportion of racial minority employees increases, the positive control and well-being relationship increases, and the positive relationship between supervisor support and well-being decreases. Further, as the proportion of African-American employees (versus white and all other racial subgroups) increases, the positive control and supervisor support relationship decreases, as does the positive coworker support and well-being relationship. Our results offer new insights into the role of workplace racial composition on how work is experienced, and job design recommendations in a time of increasing workplace racial diversity.

Forced termination of clergy involves constant negativity found in personal attacks and criticism from a small congregational faction. The minister feels psychologically pressured to step down from the ministry position and this process is often demeaning to the emotional and physical well-being of the minister. The prevalence of forced termination among clergy has ranged from 25% among many denominations to 41% among Assemblies of God ministers. Forced termination and its effects are serious problems that have yet to be adequately addressed by scholars in social science research. The lack of scholarly research in this area called for a large national study from a reputable research institution. This online study shows that 28% of ministers among 39 denominations experienced a forced termination. Forced termination was associated with high levels of depression, stress, and physical health problems. Forced termination was also associated with low levels of self-efficacy, and self-esteem.  相似文献

Three experiments examined the factors that are responsible for producing a high rate of autoshaped keypecking in pigeons when the conditioned stimulus is followed by varying consequences. In the first experiment, a single group received three serial conditioning schedules presented on different keys. The AB+ schedule consisted of trials in which A was followed by B, which, in turn, was followed by food. The CD+C° schedule consisted of reinforced CD pairings plus presentations of C alone. The EF+/0 schedule consisted of a mixture of reinforced and nonreinforced EF pairings. It was found that responding was most rapid during C, slowest during E, and at an intermediate rate during A. In spite of this ordering A was chosen in preference to C, when these stimuli were presented simultaneously. In Experiments 2 and 3 the schedules AB+A° and AB+/0 were presented to separate groups. The rate of responding during A was substantially greater in the former schedule, yet it was found that this stimulus was equally ineffective as a conditioned reinforcer in both groups. We propose that autoshaped keypecking is composed of two types of response, a conditioned response and an orienting response, which are governed by different processes.  相似文献

Brain mapping studies using dynamic imaging methods demonstrate areas regional cerebral blood flow (rCBF) decreases, as well as areas where increases, during performance of various experimental tasks. Task holds for both sets of cerebral blood flow changes (CBF), providing the opportunity to investigate areas that become and “activated” in the experimental condition relative to control state. Such data yield the intriguing observation that in areas in emotional processing, such as the amygdala, the posteromedial cortex, and the ventral anterior cingulate cortex, although flow as expected during specific emotion-related tasks, flow decreases performance of some attentionally demanding, cognitive tasks. Conversely, in some of the areas that appear to subserve cognitive functions, as the dorsal anterior cingulate and the dorsolateral prefrontal cortices, increases while performing attentionally demanding cognitive tasks, but during some experimentally induced and pathological emotional Although the specific nature of such reciprocal patterns of regional remains unclear, they may reflect an important cross-modal interaction during mental operations. The possibility that neural activity is less in areas required in emotional processing during some higher cognitive processes holds implications for the mechanisms underlying interactions cognition and emotion. Furthermore, the possibility that neural in some cognitive-processing areas is suppressed during intense states suggests mechanisms by which extreme fear or severe may interfere with cognitive performance.  相似文献

The objective of the present study was to examine if the Outcome Bias also occurs in pilots flying under instrument flight rules (IFR). In a scenario-based survey, 60 pilots evaluated weather-related decisions made by hypothetical pilots. Participants rated the decisions as better, less risky, and regarded the probability that they would have made the same decision as higher when they were followed by a positive outcome, than when they were followed by a negative outcome. This effect showed likewise for novice pilots and for experienced pilots. These findings could be relevant for the flight-related decision-making of pilots, which sometimes is affected by the decisions made by third-party pilots. In particular, decisions made by other pilots that have led to positive outcomes might be hastily followed, whereas those that have led to negative outcomes might be hastily rejected.  相似文献
