Robert Platt 《The Sociological review》1989,37(4):636-667
The paper examines, and seeks to develop, the sociological concept of reflexivity. It identifies two senses of reflexivity, one associated with ethnomethodological accounts of members’practical reasoning, the other with a more philosophical sense of conscious self-referencing, and analyses their relationship. The paper argues that the development of this form of analysis leads to a form of propositional undecidability which makes it typically ‘postmodern’. The development is linked to ideas of recursion, as these are expounded in computer science and mathematics, and to Derrida's interpretation of ‘textual fold’— this also being used to ground the association of reflexivity with postmodernism. The analysis ‘returns to the social’by considering aspects of Niklas Luhmann's explication of social reflexivity. It concludes by examining the understanding that a postmodern sociology might have of a postmodern society in which the grounds for social order have become undecidable. 相似文献

Recent research concerning the incidence of reported work-limiting disabilities in the married population indicates a degree
of interdependence between spouses' disabilities. This pattern is consistent with several hypotheses. Spouses tend to share
many lifestyle traits that might lead to common health outcomes. Alternatively, their joint reports might reflect a shared
preference for income benefits or workplace accommodations available to disabled individuals. Another possibility is that
disabled individuals tend to be matched in the process of marital formation. This paper investigates the latter hypothesis.
Taking advantage of a unique data set from the Swedish population, we select a sample of recently married couples and trace
them back in time to their single years. Our analysis indicates nonrandom matching on the basis of disability status. After
controlling for observed traits such as age and education, we find a residual correlation between future spouses that is positive
and strongly significant. The magnitude of the correlation is within the range of residual correlations obtained from other
studies that address marital matching in the contexts of education and earnings.

This paper examines the impact of economic and technological trends upon the level and structure of labour demand. It explores briefly the methods used to model the labour market with special reference to demography and technology and reviews the evidence on recent and prospective changes in labour demand for five countries: France, Germany, Italy, the Netherlands and the United Kingdom. A distinction is made between the differentforms in which job opportunities arise and the differentareas of economic activity in which they appear. Given the limited horizon of the projections available and the methodological difficulties of long-term forecasting, the focus is on medium-term changes. The findings nonetheless indicate the underlying trends that are likely to continue over the next decade or so. 相似文献

Workplace exposures to airborne chemicals are regulated in the U.S. by the Occupational Safety and Health Administration (OSHA) via the promulgation of permissible exposure limits (PELs). These limits, usually defined as eight-hour time-weighted average values, are enforced as concentrations never to be exceeded. In the case of chronic or delayed toxicants, the PEL is determined from epidemiological evidence and/or quantitative risk assessments based on long-term mean exposures or, equivalently, cumulative lifetime exposures. A statistical model was used to investigate the relation between the compliance strategy, the PEL as a limit never to be exceeded, and the health risk as measured by the probability that an individual's long-term mean exposure concentration is above the PEL. The model incorporates within-worker and between-worker variability in exposure, and assumes the relevant distributions to be log-normal. When data are inadequate to estimate the parameters of the full model, as it is in compliance inspections, it is argued that the probability of a random measurement being above the PEL must be regarded as a lower bound on the probability that a randomly selected worker's long-term mean exposure concentration will exceed the PEL. It is concluded that OSHA's compliance strategy is a reasonable, as well as a practical, means of limiting health risk for chronic or delayed toxicants. 相似文献

This article shows that in Nepal breastfeeding almost completely explains the effects of following birth interval on childhood mortality during the first 18 months of age and partially explains the effect of following birth interval on childhood mortality between 18 and 60 months of age. Breastfeeding does not explain the effect of preceding birth interval on childhood mortality. The analysis is based on application of hazard models to data from the 1976 Nepal Fertility Survey. 相似文献

Abstract The effects of previous victimization, distance from law enforcement and neighbors, and sufficiency of police patrols on fear of crime are estimated using data from Montana farmers and ranchers. Victimization has the strongest direct effect. Distance from police and neighbors seems to heighten sensitivity to lesser police patrol activity in isolated areas, which in turn increases concern about criminal victimization. Fear of crime in rural farm areas reflects, in part, the spatial arrangements and related consequences of living in these regions. 相似文献

Two studies were conducted using video records of real faces and three-dimensional schematic faces to investigate the perceptual distortions introduced by viewing faces at a vertical angle and their influence on the attribution of emotional expressions and attitudes. The results indicate that faces seen from below were perceived as morepositive and lessnegative, while faces seen from above appeared morenegative and lesspositive. This effect seems to be moderated by interindividual differences in facial morphology, and perhaps by differences in dynamic aspects of expressions. The second study investigated the respective contribution of the upper half and the lower half of the face to the perceptual distortion found. In general, judges based their attributions of emotional state more on cues from the upper half of the face. 相似文献

Examinations constitute one of the principal methods by which professions assess minimal competence in aspiring practitioners. The Examination in Marital and Family Therapy is used by most states which regulate the profession. This article provides the rationale for the examination program, describes its development and maintenance, and presents the knowledge base it samples. Administrative policies and procedures are also discussed as an aid to prospective licensure and certification candidates. 相似文献
