Evaluation of laser desorption mass spectrometry and UV accelerated aging of dyes on paper as tools for the evaluation of a questioned document 总被引:1,自引:0,他引:1
Laser desorption mass spectrometry (LDMS) may be used for the detection and identification of dyes found in inks. Naturally-aged and artificially-aged blue and black ballpoint pen inks containing the cationic dye methyl violet were analyzed on paper. The average molecular weight of the dye sample was calculated from LD mass spectral data and plotted versus time. The resulting aging curves demonstrate that, as dye degradation increases, the average molecular weight of the dye decreases. Typical variables involved in ink aging, such as the type of paper and ink formulation, were investigated. Results show that these variables influence the rate of dye degradation. Furthermore, UV accelerated aging has been developed and tested as an alternative to thermal approaches. 相似文献

Since its very inception, the United Nations has worked with NGOs (non-governmental organizations) or, to use the contemporary term, a "civil society." In fact, every single U.N. department now has an NGO liaison. As the world becomes increasingly smaller, the role and influence of NGOs will continue to be significant in international negotiations. 相似文献

Non-missile penetrating brain injuries are rare events in western countries. We report a case with lethal stab injury of the brain and identification of the weapon used in the assault by digital superimposition on CT scans taken at admission of the victim to a hospital. Furthermore, all cases with knife stab wounds of the skull between 1971 and 2000 were analyzed and compared with literature reports. Results of this study show that there is no region preference despite of differences in bone thickness, that stab wounds of the brain are almost invariably associated with multiple stab wounds to the trunk and that the wound tract may correspond to the dimensions of the blade allowing the identification of the weapon by digital image analysis. 相似文献

Several recent studies examine the degree to which congressional behavior affects candidates’ electoral fortunes (e.g., Carson, 2005). Research examining electoral competitiveness (Bond, Campbell, & Cottrill, 2001; Koetzle, 1998) and roll call voting (Bailey & Brady, 1998; Jones, 2003) finds that diversity in the electorate mediates the impact of numerous variables upon election outcomes and representation. However, the influence of diversity on other modes of representation – such as the policy positions taken by Senate candidates–remains unexplored. We investigate the link between representation and Senate candidates’ policy positions and thereby examine the degree to which voter diversity affects candidates’ policy responsiveness. We find that diversity significantly influences responsiveness, both directly and indirectly – candidates in homogenous states are more responsive to constituents than are candidates in heterogeneous states. 相似文献

The article studies the impact of the European Union (EU) on the reforms of regional administration in Central and East European (CEE) accession countries. It analyzes the motives, process and outcomes of regional– or mesolevel administrative reforms in five countries—Bulgaria, the Czech Republic, Hungary, Poland, and Slovakia—considering whether the EU has shaped these reforms to a higher degree than in relation to its incumbent member states. The article finds that the EU Commission's interest in regional self–governments with a substantial fiscal and legal autonomy has provided an additional rationale and an incentive to re–create regional self–governments. Advocates of regional self–government and an institutionalization of regions in the accession countries have referred to European trends and (perceived) EU expectations of regionalization. Thus, the Commission and the preaccession framework have become catalysts for a process in which most CEE regions have already enhanced and will further increase their political salience. However, the trajectories and outcomes of regional–level reforms can be better explained by a combination of domestic institutional legacies, policy approaches of reformers and their adversaries, and the influence of ethnic/historical regionalism. 相似文献

The 1997 British election marks a major change in British government. Eighteen years of Conservative rule had brought about growing inequality and social division and have generated powerful demands for new directions in public policy, especially in the areas of welfare and public administration. On welfare state reform Labour is constrained by election promises to restrain taxation and public expenditure. New Labour ministers influenced by the New Right have in any case largely rejected traditional social democratic redistributive strategies and are seeking instead new ways of reducing welfare dependency.
The virulent spread of quangos at all levels of government and a marked increase in the centralisation of power in Whitehall have given a new impetus to demands for constitutional reform. Labour's response to these demands is a major program of regional devolution, House of Lords reform and open government measures.
This article explains what 'New Labour' means and discusses New Labour policies on welfare and constitutional reform and their implications for the future of public administration in Britain. 相似文献
