In this study, we report the chemical analyses of various non-pathological, tuberculosis and syphilis infected bone samples from different burial environments by Fourier transform infrared spectroscopy (FT-IR), in the framework of a general study of diagenesis. Dating human skeletal remains is one of the most important and yet unreliable aspects of forensic anthropology. In this paper, a new method has been suggested, using the crystallinity index and carbonate-phosphate index as a means of distinction between recent and archaeological, anthropological bone samples. Pathological bone samples were analyzed with the same method to see if changes in crystallinity interfere with the process of dating. 相似文献

Field Experiments on Eyewitness Identification: Towards a Better Understanding of Pitfalls and Prospects 总被引:1,自引:1,他引:0
Wells GL 《Law and human behavior》2008,32(1):6-10
The Illinois pilot program on lineup procedures has helped sharpen the focus on the types of controls that are needed in eyewitness field experiments and the limits that exist for interpreting outcome measures (rates of suspect and filler identifications). A widely-known limitation of field experiments is that, unlike simulated crime experiments, the guilt or innocence of the suspects is not easily known independently of the behavior of the eyewitnesses. Less well appreciated is that the rate of identification of lineup fillers, although clearly errors, can be a misleading measure if the filler identification rate is used to assess which of two or more lineup procedures is the better procedure. Several examples are used to illustrate that there are clearly improper procedures that would yield fewer identifications of fillers than would their proper counterparts. For example, biased lineup structure (e.g., using poorly matched fillers) as well as suggestive lineup procedures (that can result from non-blind administration of lineups) would reduce filler identification errors compared to unbiased and non-suggestive procedures. Hence, under many circumstances filler identification rates can be misleading indicators of preferred methods. Comparisons of lineup procedures in future field experiments will not be easily accepted in the absence of double-blind administration methods in all conditions plus true random assignment to conditions. 相似文献

On 9 February 2004, the federal Immigration Court ruled that a Zambian woman can stay in the US because her HIV-positive status gives her a well-founded fear of persecution in Zambia. The court found that she would face severe and lethal discrimination in the public health clinics and in the employment sector and that the Zambian government is unwilling or unable to control this persecution. 相似文献

On 5 May 2004, the UK Court of Appeal, Criminal Division, granted Mohammed Dica's appeal against his October 2003 conviction on two counts of causing grievous bodily harm for reckless transmission of HIV. The court ordered a retrial after determining that the trial judge was wrong to not allow the defendant to present information that the victims had known about his condition and had consented to the risk. 相似文献

Vinyl flooring manufacturers use plasticizers to decrease the viscosity and increase the pliability of vinyl. Several ignitable liquid plasticizers used in the manufacture of vinyl flooring were identified and investigated in this study. Twenty-nine collections from five major vinyl manufacturers, a total of 72 samples, were analyzed using passive headspace concentration in accordance with the American Society for Testing and Materials (ASTM E 1412-00) and gas chromatographic-mass spectrometric (GC-MS) analysis as described in ASTM E 1618-01 (1,2). Norpar products and TXIB (2,2,4-trimethyl-1,3-pentanediol diisobutyrate) are ignitable liquids common to the manufacture of vinyl flooring and were identified in all recently obtained samples. Isopar H is an ignitable liquid found in various products such as charcoal starters, copier toners, and some solvents (2). Of the 29 collections analyzed, Isopar H was only identified in Armstrong's Interflex-Traditions pattern. 相似文献
