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.

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 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.

冷战后美国的“价值观输出” 总被引:1,自引:0,他引:1
布庆荣 《内蒙古民族大学学报》2005,(3)
“价值观输出”始终存在于美国的对外政策之中,冷战后,美国更加重视以“美国式的自由民主价值观”来整合社会主义国家和广大发展中国家,冷战后美国的价值观的输出主要围绕着“建立美国价值观主导下的世界新秩序”的战略目标,在实现手法上表现出由温和到强硬的发展态势,美国价值观输出的实质是美国当局追求国家利益的工具,美国政府对价值观输出的高度重视有其深刻的思想根源、经济动因和政治动因。 相似文献

This study investigates the extent and nature of housing affordability for elderly nonmetropolitan female heads of household
using data from the Panel Study of Income Dynamics. The results indicate that over one-third of elderly nonmetropolitan female
heads of household experience housing poverty and that those who rent, who have fair to poor health, and who are minorities
are particularly vulnerable. Housing affordability, measured by the concept of housing poverty, identifies households struggling
to meet basic needs while the conventional 25% of income for housing expenditures ratio identifies a larger population. The
findings suggest the need for multifaceted public policies to address the problem of housing poverty.
Her research interests include housing affordability, housing and community vitality, and decision making. She received her
Ph.D. from Purdue University.

behavior in relation to housing expenditure burden. She received her Ph.D. from the University of Nebraska-Lincoln. 相似文献

In the design of experiments for estimating the slope of a response surface, slope-rotatability is a desirable property. In this paper, a measure is introduced that enables us to assess the degree of slope-rotatability for a given response surface design. The measure takes the value zero if and only if the design is slope-rotatable, and becomes larger as the design deviates from a slope-rotatable design. Examples of applying this measure to some response surface designs are also given. 相似文献
