This study tested a causal model of academic self-efficacy in faculty at a large New England research university, focusing specifically on gender as one of 12 antecedent variables. Academic self-efficacy was defined as an estimate of confidence in one's ability to perform various tasks classified as research, service, and teaching in a university setting. The variables were drawn from Bandura's theory of self-efficacy and from characteristics of the university work setting. Data was obtained by mail response to a researcher-designed instrument: the Measure of Self-Efficacy in Academic Tasks (MSEAT). The findings show that being female contributed to feeling less efficacious about research tasks indirectly through the mediating influence of intervening variables. Feeling nourished and rewarded by a department and being male contributed to service self-efficacy. Teaching self-efficacy was not explained by the causal model. The implications of these findings are discussed in terms of campus socializing interventions, departmental research climate, and university incentives for female faculty. © 1988.

This investigation examined the prevalence and nature of grief in response to patient suffering, loss, or death among healthcare workers employed at a general hospital and a skilled nursing facility. A questionnaire was constructed for this purpose. Approximately two-thirds of the skilled nursing facility personnel remembered experiencing bereavement as a reaction to the crises of their geriatric patients. Mourning occurred among virtually all of the general hospital personnel who usually serve younger patients. Healthcare personnel mourned most often for those persons who suffered or died of cancer. A selected sample of respondents recalled that psychological symptoms of grief were more evident than physical. Both symptom types often persisted for more than 1 month. Since grief is common among nurses and aides employed at the two medical settings, bereavement counseling is suggested for those healthcare personnel who require this service.

The use of gradient operators for image enhancement has been widely reported in the literature, but they have not been used routinely in the medical arena, particularly in the most common radiographic plain film procedure, chest radiographs. Gradient operators such as Sobel and Roberts operators, not only enhance image edges but also tend to enhance noise. Overall, the Sobel operator was found to be superior to the Roberts operator in edge enhancement. A theoretical explanation for the superior performance of the Sobel operator was developed based on the concept of analyzing the x and y Sobel masks as linear Alters. By applying pill box, Gaussian, or median filtering prior to applying a gradient operator, noise was reduced, but the pill box and Gaussian filters were much more computationally efficient than the median filter with approximately equal effectiveness in noise reduction. © 1988 IEEE
