The discovery of participatory research as a new scientific paradigm: Personal and intellectual accounts 总被引:1,自引:1,他引:0
Peter Park 《The American Sociologist》1992,23(4):29-42
The article presents considerations for the placing of participatory research in the practice of sociology. The changing conditions
in contemporary society have compelled social scientists to rethink the way social theory has been conceptualized and has
been practiced in relation to social change. Modernist social theory, of which sociology is a prime example, has been imbued
with the biases of the Enlightenment that privilege the essentialized male rational actor set above the ordinary people. As
a consequence it has produced narratives and practices that are not in the interest of the people, especially those who have
been dominated and oppressed. In order to live up to the potential of sociology as a vehicle for the improvement of social
conditions, it must include the interest and the wisdom of the people in its researching and theorizing activities. It is
argued that participatory research provides an opportunity to follow this course in sociology. Participatory research, it
is contended, will lead to a paradigm shift in the social sciences because it is based on an expanded conception of knowledge
and because it changes the relationship between the researcher and the researched and between theory and practice. Arguments
are drawn from the history of science, critical theory, and postmodernist and feminist critiques.

Older disabled workers' perceptions of volunteering 总被引:1,自引:0,他引:1
Susan Balandin Gwynnyth Llewellyn Angela Dew Liora Ballin Julie Schneider 《Disability & Society》2006,21(7):677-692
The activity of volunteering is readily available to, and undertaken by, able-bodied people in Australia and is recognized as a valuable social pursuit, particularly among citizens of retirement age. Despite the known benefits of volunteering, however, there are few reports of disabled people participating as volunteers and little is understood of their experiences or perceptions of volunteering. The aim of this study was to explore how older workers within supported employment settings perceived the opportunities for and barriers to volunteering. Fourteen people with long-standing impairments participated in this small qualitative study. Overall the participants were positive about volunteering, but noted they might require support to volunteer successfully. Drawing upon the participants' views, recommendations are made for developing training. Disabled workers facing retirement need to be supported to have opportunities for active participation in the community as volunteers if so desired. 相似文献

An important characteristic of high-tech industries is decreasing component prices over time. In the personal computer industry, some component prices decline at a rate of 1% per week. This paper develops an inventory model for products experiencing continuous decrease in unit price. We develop an accurate closed-form approximate solution to the model. Our results indicate that declining prices lead to substantial decrease in the optimal cycle time and much frequent ordering. This explains the heavy emphasis on just-in-time inventory management practiced by successful companies in high-tech industries. While previous models attributed the success of just-in-time policies to reduced holding cost and improved quality, under declining prices a substantial source of savings becomes lower costs of raw materials which is significant part of cost in these industries. We illustrate the results of the model with a numerical example and perform sensitivity analysis. 相似文献

This study evaluates the dose-response relationship for inhalation exposure to hexavalent chromium [Cr(VI)] and lung cancer mortality for workers of a chromate production facility, and provides estimates of the carcinogenic potency. The data were analyzed using relative risk and additive risk dose-response models implemented with both Poisson and Cox regression. Potential confounding by birth cohort and smoking prevalence were also assessed. Lifetime cumulative exposure and highest monthly exposure were the dose metrics evaluated. The estimated lifetime additional risk of lung cancer mortality associated with 45 years of occupational exposure to 1 microg/m3 Cr(VI) (occupational exposure unit risk) was 0.00205 (90%CI: 0.00134, 0.00291) for the relative risk model and 0.00216 (90%CI: 0.00143, 0.00302) for the additive risk model assuming a linear dose response for cumulative exposure with a five-year lag. Extrapolating these findings to a continuous (e.g., environmental) exposure scenario yielded an environmental unit risk of 0.00978 (90%CI: 0.00640, 0.0138) for the relative risk model [e.g., a cancer slope factor of 34 (mg/kg-day)-1] and 0.0125 (90%CI: 0.00833, 0.0175) for the additive risk model. The relative risk model is preferred because it is more consistent with the expected trend for lung cancer risk with age. Based on statistical tests for exposure-related trend, there was no statistically significant increased lung cancer risk below lifetime cumulative occupational exposures of 1.0 mg-yr/m3, and no excess risk for workers whose highest average monthly exposure did not exceed the current Permissible Exposure Limit (52 microg/m3). It is acknowledged that this study had limited power to detect increases at these low exposure levels. These cancer potency estimates are comparable to those developed by U.S. regulatory agencies and should be useful for assessing the potential cancer hazard associated with inhaled Cr(VI). 相似文献

This article gives a simple result for the expression of the Fisher information in order statistics. This result enables us
to calculate easily the Fisher information in any set of order statistics whose details have been known to be messy and complicated.
We consider here its application in the optimal spacing problem where the exact Fisher information in order statistics has
been approximated with the asymptotic information or the reciprocal of the variance of a suitable estimator.

Recent work on language crossing in the U.S. has examined the temporary appropriation of African American Vernacular English by white youth in an effort to participate in the current popularity and prestige of hip–hop culture, or in order to highlight racial boundaries. While such verbal behavior probably encompasses most white use of AAVE, it is not the only way in which whites (or other non–blacks) can use the variety. This paper presents a case study of the language of a 23 year old white female who makes consistent use of many distinctive linguistic features associated with AAVE. I argue that the interaction of ideologies of race, class, localness and language allow her to be considered an ingroup member despite her biographical race. This suggests that there is a tension between academic linguistic theory and actual speaker practice in assigning authenticity to individuals, and I conclude that language ideologies and other forms of qualitative evidence should be taken into account by sociolinguists looking at the link between language and race. 相似文献

Toddlers' knowledge of the stereotyping of traditionally feminine and masculine household activities was examined using the preferential looking paradigm. Seventy‐seven 24‐month‐old infants observed a series of 9 pairs of photographs, each portraying a male and female adult engaged in the same stereotyped or gender‐neutral activity (e.g., ironing, hammering, or reading). Longer looking times were predicted on stimuli inconsistent with gender stereotypes (e.g., looking longer at the man putting on lipstick than at the woman). The results suggested that toddlers have acquired some knowledge of the gender stereotyping of feminine activities by their 2nd birthday. 相似文献
