We report a field study examining within-individual effects of workload on distress at work and daily well-being. The study was conducted using experience-sampling methodology to measure daily workload, affective distress, and blood pressure throughout and at the end of each of 10 workdays, and emotional burnout and daily strain (two indicators of low well-being) during the evening in a sample of 64 full-time employees who provided a total of 354 person-day data points. We also measured employees’ job control and perceived organizational support with a separate survey. Results showed that workload was positively associated with affective distress and blood pressure, and with the indicators of low daily well-being. Furthermore, affective distress mediated the relationship between workload and daily well-being. More importantly, job control and organizational support had cross-level moderating influences on the relationships of workload with affective distress and blood pressure such that these relationships were weaker for participants who reported having more control on their job, as well as for participants who reported receiving more organizational support.  相似文献

The public do not like, and we do not like the idea of designer babies (Ruth Deech, then Chair of the Human Fertilisation and Embryology Authority, quoted in The Independent, 18 October 2000). We are all on the slippery slope-the question we should be asking is: skis or crampons (Professor John Harris, The Centre for Social Ethics and Policy, University of Manchester, in an interview with Susan Johnson). LINGUISTIC AND CULTURAL GROUNDING OF THE DESIGNER BABY DEBATE In October 2000, news was released of the world’s first ‘designer baby’—Adam Nash who was born on 29 August 2000 in the United States. He was chosen as a donor for his sister Molly, who suffered with Fanconi Anaemia, which is a rare genetic disease. Without a bone marrow transplant, Molly would have died before the age of 10. A suitable donor had not been found, so her parents decided to undergo in vitro fertilization (IVF), and preimplantation genetic diagnosis (PGD) to select an embryo that would not carry the disease-causing gene and would become a brother and a donor for Molly. At the time of his birth, Adam’s cord blood was collected and later transplanted into his sister. Initial reports suggest that the treatment has been successful.  相似文献

This research compares two contrasting perspectives of social contagion processes associated with the organizational outcome variables of commitment and role ambiguity in organizations. The two perspectives are structural equivalence (which focuses on the positions of individuals in social networks) and cohesion (which focuses on an individual's direct communication contacts). It was hypothesized that structural equivalence would be more associated with role ambiguity and that commitment would be more associated with cohesion. The relationship between these variables and multiplex content networks was also studied. It was hypothesized that commitment was a much more broadly based concept in the sense that a number of functional content networks systematically relate to it. On the other hand, role ambiguity was hypothesized to be more closely associated with uniplex networks, especially those related to job duties and organizational goals. While there were exceptions, generally the research results supported the hypotheses relating to multiplexity. The hypotheses that structural equivalence was more associated with role ambiguity and that commitment was more associated with cohesion also were supported in this research.  相似文献

Managers ’motives (preferences for different activities or outcomes) probably determine, in part, their relative job effectiveness. This hypothesis was tested and confirmed by Nash (1966) when he developed and cross-validated a Managerial Effectiveness Key for the 1937 edition of the Strong Vocational Interest Blank (SVIB). We revised the Nash SVIB key for those items retained in the recently-revised form of SVIB (Campbell, 1966). The new key has the same validity as Nash's key and high test-retest stability for lengthy periods of time (up to twenty-two years). Validity of the key is not extremely high (about .30), but its content does denote a pattern of stable and distinct manager motives which merit study along with cognitive, aptitude, and temperament factors as potential determiners of effective managing.  相似文献

Murphy and DeShon (2000) show that interrater correlations do not provide reasonable estimates of the reliability of job performance ratings, and suggest that better estimates can be obtained by applying the methods of generalizability theory. Schmidt, Viswesvaran, and Ones (2000) criticize our suggestions as radical, and argue that: (a) the reliability of ratings should be evaluated using the parallel test model rather than the more general and more realistic generalizability model, (b) reliability and validity are distinct concepts that should not be confused, and (c) measurement models have little to do with substantive models of the processes that generate scores on a test or measure. All three of these ideas were once part of the psychometric mainstream, but progress in psychometrics over the last 3 decades has moved the field well beyond these assumptions and approaches. Modern psychometric theory calls for close linkages between measurement models and substantive models of the phenomena being measured.  相似文献

This study investigated the creative process of well‐known musicians in Brasília, Brazil and the conditions that facilitated the development of their creative abilities. A sample of 14 professional musicians (11 composers and 3 performers) participated in semi‐structured interviews to discuss the following topics: musical formation, dedicating time to music, working conditions, creativity in music, the creative process, and the importance of music in their lives. The results indicated that the majority of the musicians view creativity as a complex process supported by many factors, especially the environment. Four stages of the creative process were described by these musicians: process triggering, preparation, product elaboration, and product validation.  相似文献
