One of the sharpest critiques of law and society scholarship in recent years has come from scholars who maintain that law and society scholarship fails to address the issue of race appropriately. This essay considers several critiques of law and society scholars' engagement with issues of race and uses them to evaluate Kitty Calavita's exploration of race in Invitation to Law & Society: An Introduction to the Study of Real Law (2010). The essay advocates the use of “race as process” as a mode of analysis that will allow for greater explanatory power to law and society scholarship when it touches on racial issues. 相似文献

ABSTRACTResource allocation to and within defense budgets is grand strategy. NATO and the EU coordinate defense planning and encourage fair burden-sharing among their members. We analyze the effect of agreed planning processes, namely the “NATO Defense Planning Process (NDPP)” on the conversion of political will to resources and then to capabilities development across the transatlantic security community. In a “fog of peace” featuring diverse threats, and in which allies may disagree on strategic rivals and sources of risk, national and regional political economies shape strategy, not the other way around. 相似文献

Fingermarks formed in or by blood often require specific development techniques. This review examines techniques and materials that may be used to enhance and record fingermarks deposited in blood or fingermarks generated by blood-contaminated papillary ridges. A large number of techniques are presented here and are discussed from a chemical as well as practical perspective. It is concluded that an optimized sequence of techniques targeting both latent (non-bloody) and bloody fingermarks must be applied to detect and enhance the maximum number of marks, and therefore optimize the information content from exhibits that may bear marks in blood. 相似文献

The organic components of gunshot residue (OGSR, also called firearms discharge residue (FDR) or cartridge discharge residue (CDR)) have been studied and discussed in the literature. These residues, consisting of particulates such as burned and unburned powder as well as molecular compounds, are rarely used in casework except for purposes such as shooting reconstructions. Molecular compounds that survive the firing event or that are created as a result of the firing event could, with focused research and development, open a new avenue for forensic gunshot residue analysis. In this study, the persistence of organic gunshot residue was evaluated using diphenylamine (DPA) as a target analyte and ion mobility spectrometry (IMS) as the detection system. Samples were collected from hands using a solvent swabbing technique and the swab was analyzed using direct thermal desorption for sample introduction into the IMS. OGSR was found to persist for at least 4h. Although DPA is a widely used industrial compound, analysis of numerous blank and background samples (n~100) did not show any significant response for DPA using this detector. Variations were noted among individuals and as such, the data set does not support estimation of a half-life as has been done for traditional primer residues. No secondary transfers were observed, suggesting the possibility of skin adhesion via interactions between the lipophilic organic compounds and skin lipids. IMS proved valuable as a means of generating patterns for forensic pattern matching and shows promise as a screening tool applied to firearms discharge. 相似文献

Computational results of Niemi and Weisberg are extended to investigate the number of alternatives in the top cycle set (possible winning alternatives in a sequence of pairwise votes) when there is no Condorcet winner. With n alternatives we assume a large number of voters each equally likely to select any of the n! preference orderings. If no Condorcet winner exists, the number of members of the top cycle set is always more likely to be n or n?1 than between 3 and n?2 inclusive. As n grows the probability that all alternatives are in the top cycle set approaches 1. 相似文献
