THE ARTICULATION OF WORK THROUGH INTERACTION   总被引:2,自引:0,他引:2  
This paper offers a set of related concepts for analyzing the interactional mechanics of how work is carried out in organizations, and for analyzing the structural/organizational conditions that bear upon work performance. Our analytic discussion centers around four main concepts: (a) articulation, (b) arrangements, (c) the process of working things out, and (d) stance. These concepts directly connect interaction to work and explain why work performance often bogs down and breaks down.  相似文献

We propose some estimators of noncentrality parameters which improve upon usual unbiased estimators under quadratic loss. The distributions we consider are the noncentral chi-square and the noncentral F. However, we give more general results for the family of elliptically contoured distributions and propose a robust dominating estimator.  相似文献

This study investigated the relationship between the level of arousal (Heart Rate) and the number of erroneous perceptions among video poker players. Twelve regular and twelve occasional gamblers participated in a gambling session conducted in a natural environment. It was hypothesised that 1) a significant positive correlation would be observed between arousal and the number of erroneous verbalizations, 2) regular players would show a higher level of arousal than occasional players, and 3) they would emit more erroneous verbalizations. Results showed that hypotheses one and three were confirmed. Theoretical and practical implications of these results for the psychology of gambling are discussed.This study was supported by a grant from Loto-Québec.  相似文献

Abstract Warner and England (1995) make a welcome argument for a technological science perspective for sociology based on a theory of humans as technological agents and an epistemology that includes ethical values. As with any sociological perspective, however, Warner and England's comments help to focus on and understand some aspects of social life and not others. This commentary provides a complementary focus by emphasizing the dialectical relationship between human agency and technological agency. Furthermore, I argue that a dialectical view is necessary for grounding Warner and England's theoretical argument and for acting on their ethical argument. Implications of a dialectical perspective for the meaning and politics of technology are explored. The paper concludes with a discussion of the suitability of “science” as a metaphor for sociology.  相似文献

This study tested Super's model of career adaptability by examining the relationships between career development concerns, values, and role salience among 881 men employed full-time in a cement factory. They responded to the Adult Career Concerns Inventory, the Values Inventory, and the Salience Inventory. The inter-correlations of the resulting scores were appropriately small and coincided with theoretical predictions. A principal components analysis clarified the latent structure of the relations between and among the scales. The results supported both Super's model of career adaptation and his model for Career Development Assessment and Counseling.  相似文献

Impacts of complex emergencies or relief interventions have often been evaluated by absolute mortality compared to international standardized mortality rates. A better evaluation would be to compare with local baseline mortality of the affected populations. A projection of population-based survival data into time of emergency or intervention based on information from before the emergency may create a local baseline reference. We find a log-transformed Gaussian time series model where standard errors of the estimated rates are included in the variance to have the best forecasting capacity. However, if time-at-risk during the forecasted period is known then forecasting might be done using a Poisson time series model with overdispersion. Whatever, the standard error of the estimated rates must be included in the variance of the model either in an additive form in a Gaussian model or in a multiplicative form by overdispersion in a Poisson model. Data on which the forecasting is based must be modelled carefully concerning not only calendar-time trends but also periods with excessive frequency of events (epidemics) and seasonal variations to eliminate residual autocorrelation and to make a proper reference for comparison, reflecting changes over time during the emergency. Hence, when modelled properly it is possible to predict a reference to an emergency-affected population based on local conditions. We predicted childhood mortality during the war in Guinea-Bissau 1998-1999. We found an increased mortality in the first half-year of the war and a mortality corresponding to the expected one in the last half-year of the war.  相似文献

In this paper we reanalyze Robert D. Mare's highly influential work on educational transitions among American men born in the first half of the 20th century. Contrary to previous belief, Mare found that the effects of socioeconomic background variables decline regularly across educational transitions in conditional logistic regression analyses. We have reconfirmed Mare's findings and tested them by introducing a modified logistic response model that constrains selected social background effects to vary proportionally across educational transitions. We refer to our preferred model as the logistic response model with partial proportionality constraints (LRPPC). The model can easily be estimated in Stata or using other standard statistical software. Partial proportionality constraints may also prove useful in interpopulation comparisons based on other linear models.  相似文献

Children in the child welfare system are dependent upon Medicaid to finance services for their considerable mental health needs. This study examines the effects of Medicaid policies on mental health service use among a national probability sample of children in the child welfare system. Data for this study came from the National Survey of Child and Adolescent Well-Being, the Caring for Children in Child Welfare study, and the Area Resource File. Weighted multivariate logistic regression analyses were conducted to estimate effects of policy variables on children's use of mental health services, controlling for child-level covariates and county-level health resources. Children in counties with behavioral carve-outs under Medicaid managed care had lower odds of inpatient mental health service use. Medicaid managed care enrollment and variations in type of provider reimbursement did not affect use of mental health services. Older age, greater need for mental health services, and higher levels of caregiver education were associated with increased odds of service use. Restrictions on use of inpatient mental healthcare caused by behavioral carve-outs may disproportionately affect children in the child welfare system who have high rates of such use. Careful adoption of carve-outs is necessary to assure appropriate care for these children.  相似文献
