A method was developed to screen for pepper spray residue using instruments and methods other than those techniques commonly employed to analyze chemical residue (i.e.. gas chromatography mass spectrometry-GCMS or liquid chromatography mass spectrometry-LCMS). The method employed gas chromatography (GC), thin layer chromatography (TLC), and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) to screen for dried pepper spray stains. Pepper sprays from nine different manufacturers were investigated. Capsaicin and dihydrocapsaicin were identified and unique IR reflectance spectra are presented. An additional five compounds were presumptively found. Results showed that a particular stain could be characterized as a pepper-based stain. 相似文献

Small‐scale businessmen everywhere, and particularly in developing countries, believe that their most pressing problem, if not their only one, is lack of finance. Organisations devoted to the promotion of small business have come to believe that finance must be accompanied by management advice. It is suggested that such advice should in fact precede any consideration of financial assistance; this will not only improve the chances of effective use of the additional finance, if it is eventually provided, but, more important still, it may show that there is in fact no need for more capital at all. 相似文献

This article examines the varying authority in contemporary governance of 10 prominent economists trained and based in America during the most recent period of economic instability. Despite stemming from diverse backgrounds and adopting a variety of roles, these private actors have each increasingly sought to combine moral authority with the technical authority that has been widely challenged since the outbreak of financial crisis in 2007. The shift from esoteric scientific jargons of economese towards more explicit engagements with overtly ethical issues in a moral economese is identified as an important discursive change through which these actors sought to reconfigure their contested authority. Yet this article maintains that persistent prioritisation of market values impedes rather than supports such attempts to reassert authority. Blends of technical and moral forms of authority are considered highly unstable and not conducive to enhancing the authority of these and other prominent private actors in global governance. 相似文献
