Locating exactly where trace explosive residue samples should be sought during sample collection at bomb scenes is not specified in the published literature or guidelines; in this area, it is generally acknowledged that forensic practices are based on tradition rather than evidence. This study investigated patterns in the spatial distribution of postblast 1,3,5‐trinitro‐1,3,5‐triazocyclohexane residue from a series of unconfined detonations, over a range of sampling sites, and at two different detonation heights. The amount of residue recovered from the sites decreased as a function of distance from the center of the explosion. [Correction added after online publication 27 December 2012: In the preceding sentence, “increased” was corrected to “decreased” to agree with the conclusion of the article.] As the height of the detonations increased, more residues were found from all sampling sites. The findings of this empirical study have a number of important practical implications including determining where residue samples are best sought at crime scenes. 相似文献

In contemporary English-language political theory, conversations between liberals and their critics have been largely superseded by arguments among those placing themselves under the liberal umbrella. As the debate among those calling themselves liberals has widened, so the meaning of liberalism and construction of the liberal tradition have become increasingly contested. It is therefore appropriate to consider whether liberalism is now an essentially contested concept. Gallie's original argument about essentially contested concepts is reconstructed and evaluated and a number of contemporary approaches to liberalism are considered in its light. The significance of the passage of time is examined, and some of the theoretical and practical changes that might have contributed to liberalism becoming essentially contested are outlined. The consequences for critical thinking and fundamental criticisms of society and polity are raised, and it is suggested that liberalism provides normative resources for a society to continuously question, and potentially remake, itself. 相似文献

In December 1987 the uprising in the West Bank and Gaza Strip significantly changed the nature of the Palestinian threat to Israel and pushed the West Bank and Gaza Palestinians into the forefront of the Palestinian‐Israeli conflict. This article examines the effects of the Israeli counterinsurgency tactics on the Palestinian strategy from the period of 1967 through 1987. It proposes that the implementation of Israel's counterinsurgency policy since 1967 was a crucial factor in creating the conditions for revolution and influencing the Palestinians’ adaptation of their tactics, culminating in the intifada. 相似文献

Local public service professionals are experts who temper their use of expertise with public service ethics. Public service ethics differ from the ethical codes of most professions in that they stress external accountability. Ethical codes of private sector professions create a sense of responsibility to the profession and help undergird professional autonomy. Public service ethics emphasize public responsibility and help create public accountability. City and county managers show how public service ethics can help make experts accountable to the public. 相似文献

Abstract: With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element concentrations was investigated. Paper samples from two different vendors were microwave-digested and trace element concentrations (Mg, Al, Mn, Fe, Sr, Y, Ba, Ce, and Nd) were determined using inductively coupled plasma–mass spectrometry. Differences in concentration were assessed statistically using two-way ANOVA and Tukey's honestly significant differences test. Elemental concentrations were shown to be consistent across a single sheet as well as within a single ream of paper for each vendor. Reams from vendor A were differentiated based on Al and Ba concentration while reams from vendor B were differentiated based on Mg, Mn, and Sr concentrations. Paper was differentiated according to vendor based on significant differences in Ba, Sr, Ce, and Nd concentrations. 相似文献

The recent adoption of the new E-Money Directive by the Council of the European Union has introduced key changes to European e-money legislation. The adoption of the new directive follows the European Commission's review of the original e-money directive and the market that it was intended to facilitate, which found that e-money has yet to deliver the benefits that were anticipated. 相似文献
