An alternative and generalized excess measure and its advantages

In this paper an alternative measure for the excess, called standard archα _s , is introduced. It is only an affine transformation of the classical kurtosis, but has many advantages. It can be defined as the double relative asymptotic variance of the standard deviation and can be generalized as the double relative asymptotic variance of any other scale estimator. The inequalities between skewness and kurtosis given inTeuscher andGuiard (1995) are transformed to the corresponding inequalities between skewness and standard arch.     

服务外包——社区矫正制度发展的可能模式

我国的社区矫正是与监禁矫正相对的行刑方式。社区矫正是一种充分利用社会资源,对社区范围内的假释、监(所)外执行、管制、剥夺政治权利、缓刑等罪犯进行针对性教育改造的手段和方法。目前社区矫正制度在基层司法实践中仍然面临着体制不顺、队伍不稳、资金不足、管理不到位等问题。针对基层司法实践过程中出现的问题,从社区矫正立法、管理机制、资金、队伍建设等方面提出了相应的建议——以服务外包的方式来解决问题。     

Effects of Substance Abuse Central Intake on Treatment and Justice Costs

ABSTRACT

The cost-benefits of a central intake intervention for substance abuse treatment referrals were demonstrated using a transaction cost analysis on two cohorts of participants during the three-year initiative. Costs for clients receiving central intake services were compared with those just prior to the intervention's implementation. In order to study the relationship between substance abuse treatment costs and avoided criminal justice costs, data from three administrative data sets were used. Results indicate that clients receiving the central intake intervention had approximately a 58 percent decrease in costs compared to clients not receiving the intervention. The initiative produced opportunity cost savings to treatment, court, and correctional systems, with completion being crucial to opportunity cost savings.

Corrected likelihood ratio and score tests for the beta distribution

We present correction formulae to improve likelihood ratio and score teats for testing simple and composite hypotheses on the parameters of the beta distribution. As a special case of our results we obtain improved tests for the hypothesis that a sample is drawn from a uniform distribution on (0, 1). We present some Monte Carlo investigations to show that both corrected tests have better performances than the classical likelihood ratio and score tests at least for small sample sizes.     

Best linear unbiased quantile estimators of the logistic distribution using order statistics

This paper deals with the problem of estimating the Quantiles Q(ξ), with ξ=0.01, 0.05(0.05)0.95, 0.99 of the logistic distribution by using order statistics in small samples. Linear unbiased estimators with minimum variance BLUE based on ordered observations are constructed for sample size n = 2(1)10, 15 and 20.     

Elliptical structural models

In this paper we consider structural measurement error models within the elliptical family of distributions. We consider dependent and independent el? liptical models, each of which requires special treatment methodology. We discuss in each case estimation and hypothesis testing using maximum likelihood theory. As shown, most of the developments obtained under normal theory carries through to the dependent case. In the independent case, emphasis is placed on the ^-distribution, an important member of the elliptical family. Correcting likelihood ratio statistics in both cases is also of major interest.     

Collective memory and intergroup relations

Abstract

The paper stresses the utility of a closer link between recent reassessments of social and collective dimensions of memory and the lines of research on intergroup relations. We maintain that by this link, suprisingly not fully explored to date, both fields could profit significantly. On one side, it is possible to highlight the crucial role of collective memories in the definition of identities and of boundaries of groups. On the other side, it could be argued that the study of the ways in which collective and social memories are actually performed in intergroup context may improve the understanding of the processes involved. In our opinion, a full development of this link have been hindered by a widely diffused individualistic reading of some classical contributions in the field of collective memory, and by the growing radicalism of recent socio-constructionist approaches to the same topic. As to the first point, we propose a new reading of Bartlett's work; as to the second, we support the reduction of the clash between cognitive and socio-constructionist approaches on memory research.
