Evaluation of laser desorption mass spectrometry and UV accelerated aging of dyes on paper as tools for the evaluation of a questioned document

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.     

Cultural Cognition and Public Policy: The Case of Outpatient Commitment Laws

What explains controversy over outpatient commitment laws (OCLs), which authorize courts to order persons with mental illness to accept outpatient treatment? We hypothesized that attitudes toward OCLs reflect “cultural cognition” (DiMaggio, P. Annl Rev Sociol 23:263–287, 1997), which motivates individuals to conform their beliefs about policy-relevant facts to their cultural values. In a study involving a diverse sample of Americans (N = 1,496), we found that individuals who are hierarchical and communitarian tend to support OCLs, while those who are egalitarian and individualistic tend to oppose them. These relationships, moreover, fit the cultural cognition hypothesis: that is, rather than directly influencing OCL support, cultural values, mediated by affect, shaped individuals’ perceptions of how effectively OCLs promote public health and safety. We discuss the implications for informed public deliberation over OCLs.     

A Comparison of Cleaning Regimes for the Effective Removal of Fingerprint Deposits from Brass

Abstract:  Effective removal of fingerprint deposits is crucial for experimentation related to the corrosion of metals by fingerprint deposits. Such removal is also necessary prior to deposition of test fingerprints. The effectiveness of four regimes in removing fingerprint deposits from brass is considered. Sustained wiping of the deposit with a tissue at applied pressures of up to c . 1430 Pa or rubbing while the brass was immersed in acetone both failed to remove completely all traces of fingerprint deposits. Heating the brass to 600°C was an effective remover; however, this also oxidized the surface of the metal except where inhibited by fingerprint deposits. The most effective regime, and the only one of the four that removed all traces of deposit without affecting the properties of the metal surface, was immersion in warm soapy water while rubbing with a tissue. We propose this as the preferred method for fingerprint removal.     

The Unemployment–Output Tradeoff in Transition Economies: Does Okun's Law Apply?

This paper investigates whether an Okun-type relationship between output and unemployment is taking hold in formerly planned economies as they move towards the market. Using a first-differences variant of Okun's Law, we test for its presence in 25 transition countries divided into groups of ``reform leaders'' and ``reform laggards.'' For leaders, represented by the 10 European Union (EU) accession countries, Okun's Law is detected in both 1991–94 and 1995–2000 periods. For laggards, represented by the remaining group, it is present only for the later period and only when countries affected by wars are removed from the sample. A comparison of unemployment–output elasticities and unemployment levels in EU candidates and EU members themselves indicates that their labor markets might be converging.     

ERISA, agency costs, and the future of health care in the United States

Because so many Americans receive health insurance through their employers, the Employee Retirement Income Security Act (ERISA) of 1974 plays a dominant role in the delivery of health care in the United States. The ERISA system enables employers and insurers to save money by providing inadequate health care to employees, thereby creating incentives for these agents to act contrary to the interests of their principals. Such agency costs play a significant role in the current health care crisis and require attention when considering reform. We evaluate the two major health care reform movements by exploring the extent to which each reduces agency costs. We find that agency cost analysis clarifies the benefits, limits, and uncertainties of each approach.     

Land use and forestry based CDM in scientific peer-reviewed literature pre-and post-COP 9 in Milan

This article explores the science-policy interactions between peer-reviewed literature and decisions and declarations on Land Use, Land-Use Change and Forestry (LULUCF) projects in the Clean Development Mechanism (CDM) taken at Conference of the Parties (COP) meetings. The results are based on a literature analysis capturing 88 articles published from 1997 to 2005. By using a matrix search method and a structured reading form, the method and analysis focussed on whether issues of CDM and LULUCF were presented as ‘supportive of the inclusion of LULUCF’ and ‘critical of the inclusion of LULUCF’. A matrix search method and a structured reading form were applied. Of the 88 articles, 66% included discussions supportive to the inclusion of LULUCF. Forty-nine percent had a first author affiliated in natural sciences. Only 19% had first authors affiliated in developing countries while the same number for contributing authors was 38%. The results show no clear connection between scientific literature and decisions and declarations, but indicate that policymakers set the research agenda by declarations, while researchers feed the process up until decisions are made.

International Co-operation in Cross-Border Insolvency: HIH Insurance

The House of Lords decision in HIH Insurance raised important questions about the pari passu principle of distribution in cross-border insolvency. This comment examines the case in light of academic debate, arguing that Lord Hoffmann's application of the principle of (modified) universalism achieved distributive justice amongst HIH group creditors.     

A discussion of the merits of random man not excluded and likelihood ratios

DNA mixture interpretation is undertaken either by calculating a LR or an exclusion probability (RMNE or its complement CPI). Debate exists as to which has the greater claim. The merits and drawbacks of the two approaches are discussed. We conclude that the two matters that appear to have real force are: (1) LRs are more difficult to present in court and (2) the RMNE statistic wastes information that should be utilised.
