装备采购法律救济机制初探

在装备采购过程中．由于装备采购方地位的优越性，给承制单位造成利益损害的现象在所难免。承制单位往往采取提出询问、质疑与投诉的方式，维护自身合法权益。及时、有效地解决这些争议，对于维护装备采购制度的健康运行至关重要。借鉴国内、外政府采购制度的成功经验，分析了装备采购法律救济机制的目的、途径、机构及救济权利行使的限制；提出了构建规定明确、程序完整、简明实用的装备采购法律救济机制的建议．以进一步完善我军装备采购制度。     

步幅鉴定的统计检验

作者自1978年以来与公安系统协作,用概率统计方法定量处理步幅鉴定问题,经反复实践修正,已取得成功。仅河南周口地区公安处,使用这些方法破案,实际案例已有六十多起;并且在全国一些大案要案,如杭州某银行巨款被盗案的侦破中,使用了该方法,本文就是作者八年来这方面科研成果的一部分。     

我国刑事诉讼辩诉交易制度引入的障碍分析

辩诉交易制度对于提高刑事诉讼效率具有积极意义，但在我国刑事诉讼中引入这一制度尚存在着一定的障碍．从在制度和观念上尚未完整地确立无罪推定原则、公诉案件控辩双方诉讼地位悬殊、刑事诉讼中无证据开示制度以及刑事诉讼立法关注被害人的趋势等方面进行了分析．     

Double-blind photoarray administration as a safeguard against investigator bias.

[Correction Notice: An erratum for this article was reported in Vol 85(2) of Journal of Applied Psychology (see record 2007-17253-001). On page 947, the graphs within Figure 1 were incorrectly labeled. The corrected figure appears in this erratum.] This experiment examined whether a photoarray administrator's knowledge of a suspect's identity increased false identification rates. Fifty participant–administrators (PAs) presented 50 participant–witnesses (PWs) two perpetrator-absent photoarrays following a live staged crime involving two perpetrators. For one photoarray per trial, the experimenter revealed the suspect's identity to the PA. Each PA presented the photoarrays sequentially or simultaneously in the presence or absence of an observer. When the observer was present, PA knowledge of the suspect's identity had a biasing effect in sequential photoarrays only. This pattern did not emerge when the observer was absent. The experimental manipulations did not affect PAs' and PWs' ratings of photoarray fairness or PWs' ratings of pressure to make an identification. These data suggest that only administrators who are blind to the suspect's identity should present sequential photoarrays. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

自修复数据库选择性恢复机制

选择性恢复使得自修复数据库在发生用户错误操作或入侵事务导致的故障之后,只撤销错误操作或入侵事务以及受感染的可疑事务,而保留未受感染的合法事务.提出一种新的选择性恢复机制,使用事务依赖日志、写操作日志和事务语句日志,分别记录事务间的依赖关系、事务写操作的前像数据和事务执行语句,在故障发生后,可以使数据库恢复到故障发生前一...     

Investigating the Short Peptidome Profile of Italian Dry-Cured Ham at Different Processing Times by High-Resolution Mass Spectrometry and Chemometrics

Short peptides have been spiking interest owing to their significant contribution to the taste and functional properties of dry-cured ham. In this study, a suspect screening approach based on high-resolution mass spectrometry was employed for the comprehensive characterization of the short endogenous peptidome in dry-cured ham samples at different processing stages (14, 22, and 34 months). After careful manual spectra interpretation, a chemometric approach based on principal component analysis was employed for highlighting the differences between the three sets of samples. A total of 236 short peptide sequences was tentatively identified, including 173 natural short peptides and 63 sequences containing non-proteinogenic amino acids, the highest number ever reported for endogenous sequences in dry-cured ham. Samples in the latest processing stages presented a generally higher abundance of dipeptides, indicating residual proteolytic activity. Moreover, the several annotated modified short peptides, mainly pyroglutamination and lactoyl conjugation, allowed hypothesizing several reactions occurring over time. For the first time, several lactoyl-dipeptides were tentatively identified in dry-cured ham samples with maximum concentration in the late processing stage samples. The presented results significantly contribute to the understanding of the reaction involving short peptides that affect the sensory and functional properties of dry-cured ham.

立体足迹压痕特征定量化检验的统计方法

足迹是犯罪现场最常见的痕迹之一,但公安系统以往主要凭经验进行目估尺测的辨别,因而对足迹所提供的信息利用率较低。我们在文献[1]、[2]、[3]中,对成趟步幅特征定量化检验提供了四种检验方法,已用于实际破案,并取得了成功。本文是在步幅特征定量化统计检验的基础上,提出了对单个立体足迹压痕特征定量化检验的统计方法,经三年来反复试验,取得成功,并于87年4月通过了部级鉴定。     

Measured concentrations of consumer product chemicals in California house dust: Implications for sources,exposure, and toxicity potential

Household dust is a reservoir of various consumer product chemicals. Thus, characterizing comprehensive chemical profiles of house dust may help improve our understanding of residential chemical exposure. We have previously developed a method for detecting a broad spectrum of chemicals in dust by applying a combination of target, suspect screening, and non-target methods with mass spectrometry preceded by liquid chromatography and gas chromatography. Building upon a previous study that detected 271 compounds in 38 dust samples, we presented concentrations of 144 compounds that were confirmed and quantified by standards in the same set of samples. Ten compounds were measured with median concentrations greater than 10 000 ng/g of dust: cis-hexadec-6-enoic acid, squalene, cholesterol, vitamin E, bis(2-ethylhexyl) phthalate, dioctyl terephthalate, linoleic acid, tricaprylin, tris(1-chloroisopropyl) phosphate, and oxybenzone. We also reviewed in vitro toxicity screening data to identify compounds that were not previously detected in indoor dust but have potential for adverse health effects. Among 119 newly detected compounds, 13 had endocrine-disrupting potential and 7 had neurotoxic potential. Toxicity screening data were not available for eight biocides, which may adversely affect health. Our results strive to provide more comprehensive chemical profiles of house dust and identified information gaps for future health studies.
