基层检察机关廉政文化建设研究

检察机关作为国家的法律监督机关,既肩负着反腐倡廉的历史使命,又面临着自身建设与反腐工作的巨大挑战。在开展党的群众路线过程中,一些基层检察机关不同程度地暴露出诸如作风不正、纪律不严、执法不实、行为不廉等与党的群众路线不相符甚至对立等问题,一些领导干部、检察人员的形式主义、官僚主义、享乐主义和奢靡之风依然盛行,这既严重损害了检察机关的良好形象和执法公信力,也严重阻碍了检察工作的健康持续发展。因此,检察机关需凝聚反腐工作共识,着力加强检察廉政精神文化、行为文化、制度文化和物态文化建设,努力营造以廉为荣、以贪为耻的检察机关廉政文化氛围。     

The Accuracy of Handheld Pre‐Arrest Breath Test Instruments as a Predictor of the Evidential Breath Alcohol Test Results

Drunk driving is a serious threat to public safety. All available and appropriate tools for curbing this threat should be employed to their full extent. The handheld pre‐arrest breath test instrument (PBT) is one tool for identifying the alcohol‐impaired driver and enforcing drunk driving legislation. A set of data was evaluated (n = 1779) where the PBT instrument was employed in drunk driving arrests to develop a multivariate predictive model. When maintained and operated by trained personnel, the PBT provides a reasonable estimate of the evidential test result within the relevant forensic range (95% prediction interval:  ± 0.003 g/210 L). ROC analysis shows that a multivariate model for PBT prediction of the evidentiary alcohol concentration above versus below the legal limit of 0.08 g/210 L has excellent performance with an AUC of 0.96. These results would be of value in evidential hearings seeking to admit the PBT results in drunk driving trials.     

Evaluation of a Visualization Assay for Blood on Forensic Evidence

In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis.     

Fatal Intoxication with Methoxetamine

Methoxetamine (MXE) is a new synthetic drug of abuse structurally related to ketamine and phencyclidine. A case of a 29-year-old male with acute toxicity related to the analytically confirmed use of MXE is reported. The man was found dead at his residence. Biological material was analyzed using liquid chromatography–tandem mass spectrometry. The concentration of MXE in urine of the deceased was 85 μg/mL. Despite the vial containing the blood sample being destroyed during transportation and the blood leaking out into the cardboard packaging, the blood level of MXE was estimated. After determination of the cardboard grammage (approx. 400 g/m³) and the mean mass of the blood obtained after drying (0.1785 ± 0.0173 g per 1 mL), the estimated blood concentration of MXE was found to be 5.8 μg/mL. The high concentration of MXE in blood and urine and the circumstances of the case indicate an unintentional, fatal intoxication with this substance.     

Effects of Homeopathic Mother Tinctures on Breath Alcohol Testing

In some countries, it is illegal to drive with any detectable amount of alcohol in blood; in others, the legal limit is 0.5 g/L or lower. Recently, some defendants charged with driving under the influence of alcohol and have claimed that positive breath alcohol test results were due to the ingestion of homeopathic mother tinctures. These preparations are obtained by maceration, digestion, infusion, or decoction of herbal material in hydroalcoholic solvent. A series of tests were conducted to evaluate the alcoholic content of three homeopathic mother tinctures and their ability to produce inaccurate breath alcohol results. Nine of 30 subjects gave positive results (0.11–0.82 g/L) when tests were taken within 1 min after drinking mother tincture. All tests taken at least 15 min after the mother tincture consumption and resulted in alcohol-free readings. An observation period of 15–20 min prior to breath alcohol testing eliminates the possibility of false-positive results.     

The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.     

树立正确的执法理念 提高执法水平

当前公安执法工作在打击犯罪过程中取得了显著成效,但同时还存在着一些重实体、轻程序,重尽快破案、轻依法办案等突出问题,纠其原因,除了制度、法规缺乏完善的客观原因外,主要是执法思想不端正。因此,树立正确的执法理念,对于依法办案,提高执法水平具有重要意义。

用乙醇和正丁醇判断豚鼠溺死时间的实验探索

本文以豚鼠为实验动物，溺死后浸泡于水温为２０℃的水缸小。运用气相色谱法测定其溺死后不同浸泡时间在心、肺、肝小＃在的乙醇和正了醇含量。实验结果表明在溺死后８天内，样本中乙醇和正了醇量随浸泡时间的延长而增加，且呈高度的直线相关。其血、肺、矸中乙醇量与溺死时间的回归方程依次为ｙ１＝－１６．８２＋１２．９５Ｘ，ｙ２＝－５８．５３＋１９．２３Ｘ，ｙ３＝－３１．９１＋４７．２９Ｘ。血、肺、肝小正丁醇量与溺死时间的回归方程依次为ｙ４＝－１０．１３＋５．８６ｘ，ｙ５＝－２９．４５＋１６．１７ｘ，ｙ６＝３．７５＋１４．３１ｘ。综合分析溺死后血、肺、肝小乙醇和正丁醇，有可能作为判断溺死时间的新指标。     

违反法律、行政法规强制性规定的合同的法律效力辨析——对《合同法》第52条第5款的司法应用的解读

在司法实践中,由于不同的理解,对违反法律、行政法规强制性规定的合同法律效力的认定,在理论和司法实践中,出现了较大的偏差,因此有必要对此作进一步的澄清。本文试分析德国和台湾地区在此方面的理论和实际操作,结合我国国内立法现状,指出我国司法审判在适用该规定时,应充分考虑“强制性规定”所保护的权益与合同本身所涉权益平衡关系,并根据权益平衡结果区别确定合同的法律效力。
