通过抛尸现场确定犯罪现场一例

杀人碎尸案件是指犯罪嫌疑人将被害人尸体的全部或部分肢解为若干块(段)后,四处抛撒、掩埋、隐蔽的杀人案件.杀人碎尸案件因其案件本身所具有的疑难条件,使案件不易侦破,但有时也因抛尸地点较多,每处抛尸地点有着必然的联系.刑侦部门往往以此为突破口使案件得以侦破.     

13C4-secobarbital as the internal standard for the quantitative determination of secobarbital--a critical evaluation

In this study, 13C4-secobarbital was used as an exemplar compound to illustrate the mechanism based on which the effectiveness of a proposed internal standard (IS) could be evaluated. A deuterated analog, 2H5-secobarbital, was also studied in parallel for comparison purposes. Well-established solid-phase extraction and methylation procedures were used prior to the GC/MS measurement step. The contribution of the intensity of an ion designated for the analyte (secobarbital) by the proposed IS, and similarly, the contribution of the intensity of an ion designated for the IS by the analyte--a phenomenon termed "cross-contribution"-were evaluated based on a "direct measurement" procedure in which equimolar amounts of the analyte and the IS were used to generate intensity data. These intensity data were then used as the basis for the calculation of "cross-contribution" (in percentages) of ions designated for the analyte and the IS. Cross-contribution data were compared with the linearity data resulting from two series of standards containing 25 to 9600 ng/mL secobarbital using two sets of quantitation ion pairs--m/z 196/200 and 195/199 with 13C4-secobarbital as the IS and m/z 196/201 and 195/200 with 2HS-secobarbital as the IS. 13C4-secobarbital was found to be much less problematic and thus can serve as a very effective IS. Cross-contribution data alone cannot fully explain the observed differences resulting from the use of these two ISs; further systematic study is needed to provide better understanding of the underlying interference mechanism.     

Characterization of allegedly musk-containing medicinal products in Taiwan

As a highly valued ingredient of Chinese medicinal remedies, musk is used as a detoxification agent and for treating fever, inflammation and swelling, and pain. Muscone (3-methylcyclopentadecanone-1), an odoriferous secretion from the ventral glands of male musk deer, is believed to be the active ingredient. A small amount of muscopyridine is also found in the secretion from the ventral glands of male musk deer. Common counterfeit ingredients are musk xylene, musk ambrette, musk ketone, and diphenhydramine. An extraction/GC-MS protocol/data evaluation scheme was developed and applied to study allegedly musk-containing Musk-Tiger Bone Plaster preparations and musk pods (or grains) from Chinese medicine stores and an airport customs. The content of muscone in a specific sample was estimated based on the percentage of the amount recovered from the first extraction. No muscone or counterfeit ingredients were found in all musk pod (or grain) samples from the customs and in the majority of Musk-Tiger Bone Plaster preparations, while muscone (alone or with counterfeit ingredients) was found in most of the musk pod (or grain) collected from Chinese medicine stores.

Pharmacogenomics as an aspect of molecular autopsy for forensic pathology/toxicology: does genotyping CYP 2D6 serve as an adjunct for certifying methadone toxicity?

Pharmacogenomics, applied as an aspect of molecular autopsy, may be used as an adjunct for certifying methadone fatalities. Methadone is metabolized by cytochrome P-450 (CYP) 1A2, 3A4, and 2D6. We hypothesized that methadone toxicity may be partially due to CYP 2D6 *3, *4, and *5 variant alleles, resulting in poor drug metabolism. A retrospective analysis was performed on covariables and risk factors of 21 methadone cases from the Milwaukee County Medical Examiner's Office (1998-2000). PCR genotyping showed: one heterozygous for 2D6*3, two homozygous for 2D6*4, five heterozygous for 2D6*4, and one heterozygous for both 2D6*3 and *4. This limited number of cases showed that the prevalence of poor metabolizer was higher but not significantly different from that of a control group (n = 23) (P > 0.05, Fisher Exact Test). Thus, CYP 2D6 mutations may not yet be directly associated with methadone toxicity. However, pharmacogenomics, complementing other case findings, served as an adjunct in interpreting methadone toxicity of poor and intermediate metabolizers.     

On the pricing and benefit structure of a private club or public utility

In this study the structure-induced equilibrium approach for modeling democratic institutions is extended to allow for the added structural features of executive veto and legislative override. A multidimensional model is presented for a budgetary process involving three actors — a legislature, an appropriations committee, and an executive. In order to focus attention on the role of the veto and override possibilities, simplifying assumptions are made with regard to other aspects of the agenda formation process. In particular, the committee has monopoly agenda power, a closed amendment control rule is operative, and perfect-foresight expectations are held by the committee and the executive. Given these assumptions, utility maximization by the several actors generates a budget outcome characterized as a structure-induced equilibrium. The general model is illustrated geometrically with a two-dimensional example, permitting budget outcomes to be analyzed for various combinations of veto rules and override provisions. The analysis demonstrates that budget outcomes are sensitive to alternative specifications of veto rules and override provisions. In the illustration, executive veto power is shown to vary directly with both the permissiveness of the veto rule and the stringency of the override provision. Similar relationships, however, are not found to exist for total budget expenditures.

多民族后发国家现代化进程中的族际政治整合与政治文明建设

目前世界上大多数发展中国家是多民族国家,维护国内的政治稳定构成了这些实现现代化发展的重要前提.其中,加强和改进多民族国家的族际政治整合,推进政治文明建设构成了多民族国家实现政治稳定的重要内容,两者相互联系,特别是后者对族际政治整合具有优先地位.本论文以后发国家为研究对象,分析了现代化发展对后发国家带来的影响,及其族际政治整合的基本内容以及政治文明建设之间的重要意义.     

基于信息非对称的政府信用流失与行政成本风险

政府信用与行政成本是现代政府所面临的重要问题,同时它们联系十分紧密,政府信用状况对提高或降低行政成本起着非常重要的作用。由于信息非对称导致的政府信用流失会形成一定的行政成本风险,因此必须更好地从提升政府信用着手来降低政府行政成本。
