This paper presents a formal framework that purports to capture some aspects of Kant's theory of freedom. In particular, we argue that the analysis sheds further light on Kant's distinction between a negative and a positive concept of freedom. The paper shows that the two concepts are not equivalent: we not only argue that in a Kantian perspective negative freedom need not entail positive freedom, but also that there are situations in which a person can be said to be positively but not negatively free (in a Kantian sense).  相似文献

Within institutions that provide assistance to victims of domestic violence, professionals and volunteers work as advocates for their clients at the same time that they act as gatekeepers for their agencies. While the labor of advocacy consists of empowering clients and validating their concerns and feelings, the task of gatekeeping entails making judgments about them in order to dole out goods and services. Thirty protective order interviews and their resulting affidavits form the data for this study. These interviews take place in a district attorney's office and in a pro bono law clinic. This micro-level analysis of the verbal interaction between protective order application interviewers (both paid and volunteer) and their Latina clients investigates what positive politeness strategies can reveal about how interviewers construct the conflicting discursive identities of advocate and gatekeeper. I examine what interviewers say to clients as well as how interviewers allow clients to give their accounts of abuse. The study points to specific linguistic techniques that may leave victims feeling unaccompanied in the sociolegal system. I suggest that one consequence of the gatekeeping required of interviewers is that victim-survivors may perceive a 'second assault' by the institutions meant to serve them. Linguistic phenomena particular to Latina women in the United States are also brought to light.  相似文献

Maximum likelihood estimators are investigated a for lr-out-of 2:G repairable system when failures and repairs are statistically dependent. Under two censoring schemes Accelerated Life Testing Procedure (ALTP) is used to obtain the estimates. Information matrices are supplied and a special case when the failure and repair phenomenon are independent of each other is considered.  相似文献

Abstract

An increasing interest in positive youth development has led to the creation and expansion of programs and initiatives related to youth involvement and engagement. This article focuses on the Community Development for Healthy Children initiative, which envisions making Kansas the best state in the nation in which to raise a child. The initiative includes three primary strategies: A multi-media campaign; technical assistance and support to local communities; and mini-grant opportunities. The paper provides examples of activities from across the state that promote youth involvement. Outcomes across four areas are examined, and the benefits and challenges of this initiative are also discussed.  相似文献

There has been much recent interest in supersaturated designs and their application in factor screening experiments. Supersaturated designs have mainly been constructed by using the E ( s 2)-optimality criterion originally proposed by Booth and Cox in 1962. However, until now E ( s 2)-optimal designs have only been established with certainty for n experimental runs when the number of factors m is a multiple of n-1 , and in adjacent cases where m = q ( n -1) + r (| r | 2, q an integer). A method of constructing E ( s 2)-optimal designs is presented which allows a reasonably complete solution to be found for various numbers of runs n including n ,=8 12, 16, 20, 24, 32, 40, 48, 64.  相似文献

In this paper, bivariate binomial distributions generated by extreme bivariate Bernoulli distributions are obtained and studied. Representation of the bivariate binomial distribution generated by a convex combination of extreme bivariate Bernoulli distributions as a mixture of distributions in the class of bivariate binomial distribution generated by extreme bivariate Bernoulli distribution is obtained. A subfamily of bivariate binomial distributions exhibiting the property of positive and negative dependence is constructed. Some results on positive dependence notions as it relates to the bivariate binomial distribution generated by extreme bivariate Bernoulli distribution and a linear combination of such distributions are obtained.  相似文献
