关于检察机关提起民事诉讼的几点思考

检察机关能否代表国家提起民事诉讼,我国法律没有明确规定,实践中各地检察机关和人民法院的做法各不相同。立法应尽快明确赋予检察机关代表国家和公共利益提起民事诉讼的权力,精心设置人民法院审理检察机关提起民事诉讼案件的相关程序等问题。

Socioeconomic evaluation of a correctional programme in Sweden—long-term effects Samhällsekonomisk utvärdering av ett kriminalvårdsprogram i Sverige—långsiktiga effekter

The present article focuses on the long-term socioeconomic outcome of a correctional programme in Sweden, called KrAmi (n=62), using a systematic comparison with a control group of probation clients (n=51). The evaluation, which had a quasi-experimental design, was based on actual costs for each client (n=113) for a period of five years, from 1995 to 1999. The follow-up period was two years, during which the socioeconomic costs decreased step-wise for both groups, probation groups more so than programme groups. The deteriorations were 70–80% compared to the period before treatment. Rehabilitation to labour market, measured in pension points, was more successful for programme groups than for control groups. Thanks to this, as well as lower costs during the treatment period, the programme groups’ socioeconomic profitability, measured with a 15-year cost–benefit analysis (CBA), was greater than that of the control groups. The cost–effectiveness analysis (CEA) shows that the KrAmi groups are better off in work rehabilitation, depreciation time (one year compared with two and a half years for probation groups) and repayment ratio (14 SEK compared to 6 SEK for probation groups) although cost savings are greater for probation groups.

Shannon Information Properties of the Endpoints of Record Coverage

This paper addresses the largest and the smallest observations, at the times when a new record of either kind (upper or lower) occurs, which are it called the current upper and lower record, respectively. We examine the entropy properties of these statistics, especially the difference between entropy of upper and lower bounds of record coverage. The results are presented for some common parametric families of distributions. Several upper and lower bounds, in terms of the entropy of parent distribution, for the entropy of current records are obtained. It is shown that mutual information, as well as Kullback–Leibler distance between the endpoints of record coverage, Kullback–Leibler distance between data distribution, and current records, are all distribution-free.     

Discrete adaptive design in attribute life testing

Properties of a discrete adaptive design in attribute life testing situation are studied. It is shown that the design is strongly consistent and asymptotically normal. Some examples are discussed to show that the design could be used in a wide range of ields, Finally, we give some simulation results to compare the discrete adaptive desigin with some continuous optimal designs.
