论"入世"后的职务犯罪及其防治

我国“入世” ,经济运行环境和行政管理模式将发生变化。关税减让、政务公开 ,减少了职务犯罪的机会 ;贸易自由、审批权集中 ,增大了职务犯罪的可能性。减少由“入世”给防治职务犯罪带来的消极影响 ,其根本措施仍是继续坚持“教育是基础 ,法制是保障 ,监督是关键”的方针 ,打防结合 ,标本兼治     

Contre-exemple au théorème de P.C. Consul sur la factorisation des distributions de Poisson généralisées

This note exhibits two independent random variables on integers, X₁ and X₂, such that neither X₁ nor X₂ has a generalized Poisson distribution, but X₁ + X₂ has. This contradicts statements made by Professor Consul in his recent book.

Sampling Strategies for Toxic Air Contaminants

Annual concentrations of toxic air contaminants are of primary concern from the perspective of chronic human exposure assessment and risk analysis. Despite recent advances in air quality monitoring technology, resource and technical constraints often impose limitations on the availability of a sufficient number of ambient concentration measurements for performing environmental risk analysis. Therefore, sample size limitations, representativeness of data, and uncertainties in the estimated annual mean concentration must be examined before performing quantitative risk analysis. In this paper, we discuss several factors that need to be considered in designing field-sampling programs for toxic air contaminants and in verifying compliance with environmental regulations. Specifically, we examine the behavior of SO2, TSP, and CO data as surrogates for toxic air contaminants and as examples of point source, area source, and line source-dominated pollutants, respectively, from the standpoint of sampling design. We demonstrate the use of bootstrap resampling method and normal theory in estimating the annual mean concentration and its 95% confidence bounds from limited sampling data, and illustrate the application of operating characteristic (OC) curves to determine optimum sample size and other sampling strategies. We also outline a statistical procedure, based on a one-sided t-test, that utilizes the sampled concentration data for evaluating whether a sampling site is compliance with relevant ambient guideline concentrations for toxic air contaminants.     

基于最大熵谱估计的机载雷达杂波抑制技术

在讨论机载雷达地面杂波的基础上，利用最大熵估计法对机载雷达杂波进行抑制，并引入了ｃｈｏｌｃｓｋｙ分解快速算法求解最大熵谱的ＡＲ模型参数。计算机模拟表明，基于最大熵谱估计的机载雷达杂波抑制技术有很高的谱分辨率，不仅能跟踪主杂波的频率位置而且能跟踪其谱宽度，因而具有较为满意的杂波对消化与改善因子。     

SHOULD WE ESTIMATE THE PROBABILITY OF CORRECT SELECTION?

Various authors, given k location parameters, have considered lower confidence bounds on (standardized) dserences between the largest and each of the other k - 1 parameters. They have then used these bounds to put lower confidence bounds on the probability of correct selection (PCS) in the same experiment (as was used for finding the lower bounds on differences). It is pointed out that this is an inappropriate inference procedure. Moreover, if the PCS refers to some later experiment it is shown that if a non-trivial confidence bound is possible then it is already possible to conclude, with greater confidence, that correct selection has occurred in the first experiment. The short answer to the question in the title is therefore ‘No’, but this should be qualified in the case of a Bayesian analysis.     

论犯罪构成的诉讼机能

犯罪构成的阶层性或平面性。不能决定“法庭话语权的平衡”和刑法的人权保障机能。犯罪构成模式能够设置一定的诉讼规则，体现一定的诉讼职能和目标。大陆法系阶层递进式犯罪构成模式，设置的是普通法系的可废除诉讼规则。由于缺乏程序要件的保障，虽然有利于提高司法效率。却有损司法公平，不利于人权保障，不值得借鉴。     

切入“历史”后的视点——论“新历史小说”的叙事角度

“新历史小说”，自生成之日起就存在着命名、指认等一系列问题上的争议，这一现象的出现，除了与其自身内涵和外延的不确定性有关之外，还与其叙事上的独特角度密不可分。有鉴于此，结合“新历史小说”出现的时代背景，通过对其结构特质的三个主要方面，即第一人称视角与“历史”同步、聚焦变换与情感演绎、民间视野及其视点应用进行阐释，就成为一道重要的逻辑线索。     

宗族与风俗:明代中后期社会变迁的缩影——以浙江余姚江南徐氏为例

明嘉靖万历时浙江绍兴府余姚地区的社会风俗变化很大,并深刻影响到生活方式以及人们的观念。嘉靖时徐天泽将风俗的变化归结为人们的"物欲",在讲求"义"的伦理政治下,"物欲"表现出的"利"对于社会的冲击无疑是巨大的。人们不再安分守己,以满足欲望为追求。余姚江南徐氏在明代由于科举人才辈出,引人注目。地方志从批判的角度记载风俗奢靡,编纂者号召人们移风易俗,反映了地方官的意志以及地方绅士的主张。最值得注意的是,士大夫通过宗族建设来移风易俗,维护社会秩序,造成宗族乡约化,进而组织化。
