关于农村经济结构调整的一种解说

调整农村经济结构一直是国家农村经济发展政策的重要内容。但农村经济结构调整仍存在重大障碍。只有实行宏观规划,采取综合性措施,才能逐步达到农村经济结构合理化目标。     

Appearance of chemical burns resulting from the washing of a deceased body with bleach

The authors report on a case of postmortem washing of a body with bleach. An adult female victim was found nude in an alleyway with both hands removed in the City of Westminster, CO. Cause of death was attributed to severe blunt force trauma to the head. The victim had been dumped in the alleyway within 7 h of discovery. Evidence discovered at the crime scene and autopsy indicated that the murder and subsequent washing of the body with bleach occurred at a secondary location(s). The victim was wet to the touch, presenting a strong odor of bleach. Several "ribbon"-like burn patterns were observed on the victim's back and upper thighs. These burn marks were replicated by dowsing a deceased pig with an over-the-counter concentration of bleach.

浅谈我国社会保障立法的完善

社会保障立法推动着我国社会保障的改革和制度创新。但社会保障立法远远落后于我国社会保障实践,难以适应不断发展的社会保障需要的现实是不容回避的。当前应加快社会保障立法的步伐,制定符合我国国情和社会保障制度改革急需的法律、法规,建立由社会保障实体法、社会保障基金法、社会保障组织法、社会保障程序法等组合而成的完备的社会保障法律体系。     

Medical regulation of cognitive enhancement devices: some concerns

The authors present a cogent and detailed case for altering the Medical Devices Directive to allow regulation of cognitive enhancement devices (CEDs). Protection against significant risk of harm, especially for the vulnerable, and promotion of benefit through informed use of CEDs are all good features of the proposal. However, the pre-market approval process has limitations, which we explore. We raise the possibility of ‘risk compensation’ in response to the introduction of safety measures, which could alter its effectiveness. The proposal alludes to use of ‘formally trained practitioners,’ which provide a further tier of regulation for CEDs within the proposal. We consider some positive and negative implications of this aspect of the proposal that might warrant further consideration.     

A novel chitosan/tripolyphosphate/L‐lysine conjugates for latent fingerprints detection and enhancement

Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various (bio)polymers with the aforementioned purpose. Although chitosan is widely used in medicine, pharmacy, food, and drug delivery systems, there are very few studies that address this biopolymer utilization in forensic applications, such as the detection of latent fingerprints. We used chitosan crosslinked with sodium tripolyphosphate and conjugated with L‐lysine to enhance the visualization of latent fingerprints, due to its ability to interact with fingerprint sweat residues. These conjugates were prepared using different (w/w) amounts of chitosan and tripolyphosphate (6/1; 4/1; 1/1; 1/4; and 1/6), and those with the most promising results (i.e., 6/1 formulation) were investigated in detail. Fourier transform infrared (FT‐IR) spectroscopy confirmed interactions between components of the systems. Optical microscopy and scanning electron microscope (SEM) analysis showed that prepared powder formulations were uniform in size and confirmed that chitosan/tripolyphosphate/lysine conjugates bind easily to the sweat and lipid residues present in the latent fingerprints. The testing of prepared conjugates demonstrated the potential of these systems as bio‐based powder substitution for commercially available powders.     

我国法医临床学鉴定标准现状与展望

技术标准是一个行业发展的技术支撑,也是质量控制现代化的基础性手段。我国的法医临床学经过近四十年的发展,目前已有各类规范性技术文件23部,案件量逾100万件/年。本文从标准级别、颁布部门、实施时间等方面系统复习了这些标准,可以看出:相关技术标准制订过程中大量吸纳了国际先进理念,同时也吸纳了法医临床学鉴定实践经验;目前,标准体系已初步形成。当然,目前实施的标准也存在诸多问题,如:彼此间矛盾突出、部分标准不符合技术标准的形式要件、对国际标准的研究不够深入、部分标准欠缺等等,标准化建设任务依然艰巨。未来,法医学工作者仍需加强标准与法律法规衔接的配套研究;加强国际标准跟踪、评价的研究,以形成更多的具有国际先进水平的适合我国国情的国家标准。

Implementation and Optimization of the Sodium‐Rhodizonate Method for Chemographic Shooting Distance Estimation

In shooting incident investigations where it is important to estimate the shooting distance, the sodium‐rhodizonate coloring method has been used for the visualization of GSR patterns extensively. This publication describes the optimization of this method by the use of a heated press for the transfer of GSR traces on garments, as well as variation of a number of other important process parameters. Our final aim for this project was to prepare a formal validation of the coloring method as prerequisite for its inclusion into the scope of ISO17025‐certified methods in the GSR Laboratory. A number of important factors and process parameters were identified, such as buffer composition and pH, type of textile used as a substrate and resolution of the documentation of the results. Results were tested using a synthetic proficiency test. Our optimized method has been found to be a very effective technique for visualization of macroscopic GSR traces.     

Comparison of Rehydration Techniques for Fingerprinting the Deceased after Mummification

Postmortem decay causes fingertip decomposition, desiccation, shriveling, and rigidity, reducing the possibility of obtaining sufficiently clear fingerprints for identification. In this study, five rehydration solutions (ammonium hydroxide, sodium carbonate, potassium hydroxide, urea, and warm water) followed by three fingerprint recording methods (photograph, inking roll, and dusting tape) were investigated to process mummified fingertips from an unidentified cadaver. The results show that sodium carbonate treatment is the most effective for minutiae restoration, followed by ammonium hydroxide treatment. This study also demonstrates that even those fingertips that previously failed in urea solution, 1% potassium hydroxide solution, and warm water treatment could be further improved with sodium carbonate solution to obtain qualified minutiae for fingerprint matching. The optimal procedure is rehydrating the desiccated fingertips with sodium carbonate solution for 24 h followed by dusting the finger and transferring the print to adhesive tape.
