Abstract: The early stages of adipocere formation in both pig and human adipose tissue in aqueous environments have been investigated. The aims were to determine the short-term changes occurring to fat deposits during decomposition and to ascertain the suitability of pigs as models for human decomposition. Subcutaneous adipose tissue from both species after immersion in distilled water for up to six months was compared using Fourier transform infrared spectroscopy, gas chromatography-mass spectrometry and inductively coupled plasma-mass spectrometry. Changes associated with decomposition were observed, but no adipocere was formed during the initial month of decomposition for either tissue type. Early-stage adipocere formation in pig samples during later months was detected. The variable time courses for adipose tissue decomposition were attributed to differences in the distribution of total fatty acids between species. Variations in the amount of sodium, potassium, calcium, and magnesium were also detected between species. The study shows that differences in total fatty acid composition between species need to be considered when interpreting results from experimental decomposition studies using pigs as human body analogs. 相似文献

The paper critically evaluates the thesis of the interchangeability between the think-tank public intellectual and the academic public intellectual. It suggests that this thesis, while endorsing the rise of the think-tank public intellectual, pronounces the salience of the intellectual-social critic and undermines the authority of academic public intellectuals. It is argued that the think-tank expert doubling as the public intellectuals could limit the political relevance of the academic public intellectual and that the think-tank expert’s monopolization of the public forum could present a threat to the quality of public debates. While recognizing that there are many contradictions inherent in the role of intellectual and that there are now numerous factors that hinder the abilities of academics to act as public intellectuals, the paper emphasizes public academic intellectuals’ contribution to the dynamics of public opinion and the quality of democratic standards. In today’s context, with the omnipresent of media, the new conditions of knowledge production, the neo-liberal ethos and the social prominence of think-tank experts, the sources of the academic public intellectual authority are in a continuous need for reinvestment. 相似文献

This study evaluated the compatibility of the most common enhancement methods and lifting techniques with DNA profiling. Emphasis is placed on modern lifting techniques (i.e., gelatin lifters and Isomark?) and historical fingerprint lifts for which limited research has been previously conducted. A total of 180 fingerprints were deposited on a glass surface, enhanced, lifted, and processed for DNA typing. DNA could be extracted and profiled for all the powders and lifts tested and from both groomed fingerprints and natural prints with no significant difference in the percentage of profile recovered. DNA profiles could also be obtained from historical fingerprint lifts (79.2% of 72 lifts) with one or more alleles detected. These results demonstrate the compatibility between different powder/lift combinations and DNA profiling therefore augmenting the evidential value of fingerprints in forensic casework. 相似文献

The new intramarital distributions of 190 young parents in their third month of first parenthood were studied in a multifaceted distributive and procedural justice framework. For a large majority, justice was an important dimension in their intramarital distributions of household labor, child care, leisure time, breadwinning. Justice ratings of various principles in general were more liberal than the reported practice, in women even more than in men. The practice reported was mainly traditional, with a gender-segregated distribution of labor. A pattern of marked consistencies and inconsistencies between the principles rated as just and factual practice emerged. Inconsistencies occurred more often in women than in men. 相似文献

Full DNA profiles can be generated from just a few cells; however these profiles can be contaminated from other cell types present at the crime scene. We report here on the development of an immunofluorescent technique to spatially locate human-specific blood in situ and also on the ability of this technique to detect individual leukocytes and the DNA contained within them. Four monoclonal mouse anti-human antibodies were evaluated; anti-glycophorin A to detect erythrocytes and anti-CD45, anti-myeloperoxidase (MPO) and anti-histone H1 to detect the nucleated leukocytes. Each antibody was labeled with either Alexa Fluor 488 or 568 for direct application to blood smears which allowed the simultaneous detection of erythrocytes and leukocytes. Furthermore, because histones are DNA binding proteins, the application of anti-histone H1 allowed the detection of DNA within a blood smear. Importantly it was found that full DNA profiles could be achieved after using this method with similar peak area ratios compared to untreated cells. The fluorescent antibodies were found to be human-specific with the exception of anti-histone H1 due to its conserved sequence. However, used in combination with anti-CD45 or anti-MPO the location of DNA from human-specific leukocytes could be detected. The technique was also tested on older blood stains and was still found to be sensitive and cell-specific after 4 months. Following the optimization of the methodology, the fluorescent antibodies were applied to short lengths of black cotton fibres covered with human blood spots. Although the background fluorescence from the cotton was found to be high, erythrocytes and even individual leukocytes could easily be detected, indicating that this technique could be used to detect extremely minute amounts of blood. Used in combination with laser capture microdissection (LCM), this method could be used to pick off individual leukocytes for LCN DNA techniques. 相似文献

In order to cope with the demanding workload for DNA profiling of forensic casework samples a concept for a semi-automated processing system was developed at the Landeskriminalamt (Office of Criminal Investigation) Baden-Württemberg, Germany [K. Vollack, et al., Implementation of a semi-automated processing system for DNA profiling of forensic casework samples, this issue]. The applied magnetic bead extraction method is based on ChargeSwitch® Technology (CST) from Invitrogen and was established on a liquid handling workstation Freedom EVO® 150 from Tecan. 相似文献

The Challenges of Contracting and Accountability Across the Federal System: From Ambulances to Space Shuttles 总被引:1,自引:0,他引:1
This article focuses on two questions related lo governmentcontracting and accountability. How are key components of contractingsimilar or different for city, state, and federal governmentsin the United States? To what extent do the three levels ofgovernment share the widely recognized challenges of contractdesign and contract management? To address these questions,we compared and contrasted six contracting cases, two each forlocal, state, and the federal governments. We found that forall governments in the U.S. federal system, the public managementfunctions of contracting are remarkably similar, and that contractmanagement and the achievement of accountability are "weak links"in the contracting process. Our findings do not support thehypothesis that contract management is more effective in localgovernment relative to state and federal governments. 相似文献
