Overload, autonomy, and burnout as predictors of physicians' quality of care.

A model in which perceived overload and burnout mediated the relations of workload and autonomy with physicians' quality of care to their patients was examined. The study was based on data from 890 specialists representing six medical specialties. Including global burnout as well as its three first-order facets of physical fatigue, cognitive weariness, and emotional exhaustion improved the fit between the structural model and the data relative to an alternative model that included only global burnout. Workload (number of work hours) indirectly predicted quality of care through perceived overload. Additionally, the authors found that the paths from the first order factors of emotional exhaustion, physical fatigue, and cognitive weariness predicted quality of care negatively, positively, and nonsignificantly, respectively.

Effect of electrical insulation coating on thermal state of superconducting busbars

It is demonstrated, on the basis of experimental data, that a high thermal resistance of the coating can facilitate transition of a superconductor to the normal state with attendant release of heat in amounts below the first critical level.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 42, No. 5, pp. 709–714, May, 1982.     

Determinants of perceived social support: Interpersonal transactions, personal outlook, and transient affective states.

During the last decade, the study of social support has relied heavily on recipients' reports of perceived support. However, such reports of support may reflect not only actual supportive interpersonal transactions but also the recipients' own personal and perceptual dispositions and comparatively transient mood states. This study examines these factors' independent effects on perceived support. Interpersonal transactions of social support were assessed in a longitudinal panel design using reports from 486 adult male respondents and their significant others (mostly wives). Using structural modeling techniques ({lisrel vi}), an unfolding series of statistical analyses were performed. The results provide strong support for a model in which recipients' perception of support is determined significantly and strongly by actual interpersonal transactions as reported by significant others, moderately by the recipients' negative outlook bias, and weakly by their anxiety and depression as indicators of their poor mental health. The implications of the results for future research are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Hall-array measurements of flux creep parameters in Y-Ba-Cu-O crystals

We describe the details of a new method for studying thermally activated flux creep in superconductors. this method employs an array of microscopic Hall sensors to probe the time evolution of the field profile in the sample. We analyze these data on the basis of a continuity equation which takes into account contributions to the relaxation process from both the in-plane and out-of-plane components of the induction field. This analysis enables direct determination of flux creep parameters such as the flux-line current density, flux-line velocity and the activation energy for flux creep. We demonstrate this method by presenting experimental data for YBa₂Cu₃O_7-x crystals in the remanent state and in the presence of a field.
