“Shaping history” or “Riding the wave”?: President Bush's influence on the public opinion of terrorism, homeland security, & crime

The theory of presidential influence over public opinion is used to predict the impact of presidential rhetoric on the public's concern for terrorism, homeland security, and crime as the “most important problems facing the country.” Using OLS time-series regression, the authors find consistent results that President Bush influenced public opinion in relation to terrorism, homeland security and crime, despite the overwhelming events of September 11th and its impact. The article concludes by discussing the president's ability to shape events and how some events shape the presidency.     

Results of four inter-laboratory comparisons provided by the Forensic Isotope Ratio Mass Spectrometry (FIRMS) network

Between 2004 and 2008 the Forensic Isotope Ratio Mass Spectrometry (FIRMS) network organised four Inter-Laboratory Camparison excercises with the aim of harmonising and validating isotopic measurements to be used for forensic applications.The samples distributed comprised materials of potential forensic interest such as packaging and pharmaceuticals to be analysed for δ²H, δ¹³C, δ¹⁵N and δ¹⁸O composition. As many as 30 international laboratories participated in these comparisons. Results have shown overall improvements for both within- and inter-laboratory reproducibility with respect to δ¹³C and δ¹⁵N measurements.Only a small number of laboratories returned results for δ²H and δ¹⁸O analysis and these results highlighted a need for improvement in the reproducibility of these measurements and a need to address the exchange of hydrogen between samples and ambient moisture. Results also highlighted the importance of sample preparation procedures and the need to standardise both these procedures and calibration against Standard Reference Materials. Future Inter-Laboratory Comparison exercises will assess the suitability of laboratories to submit data to national and international databases similar to those currently operated for fingerprints, DNA etc.     

Uses of the NIST 26plex STR assay for human identity testing

Ongoing work at the U.S. National Institute of Standards and Technology has focused on the characterization of 26 autosomal STR loci for human identity testing. These 26 loci are in addition to the existing 13 U.S. core loci and those found in PowerPlex16 and Identifiler commercial STR typing kits. The amplification of the 26 loci has been optimized for degraded extracts in unique miniplex panels and also for reference samples as a single reaction 26plex assay. A study has been performed comparing genotypes obtained with the 26plex primers to those with miniplex panels for allele drop out and concordance. The forensic utility of the 26plex assay was evaluated for situations where additional loci are beneficial. The utility of this large multiplex was also tested in a case involving DNA extracted from degraded bone samples. The 26plex can serve as a low-cost assay (compared to commercially available kits) useful for both sorting comingled remains and providing additional markers for increased statistical support for samples that require “non-trio” family references for human identification.     

The ‘private plot’ in Soviet agriculture

The paper examines the main components of Mexican agrarian populism, and the attractions of the populist position in the light of the current crisis within the Mexican agricultural sector. It is suggested that the ‘campesinistas’ (agrarian populists) have incorporated various aspects of marxist analysis, but have nevertheless emphasised ways in which their approach pans company with that of most marxists in Latin America. According to writers like Gustavo Esteva, perhaps the leading ‘campesinista’, the peasant economy in the process of developing can co‐exist with capitalism for a protracted period, and considerable doubt exists as to whether the peasant economy is ‘ultimately’ inconsistent with capitalist development. The agrarian populists look to the peasantry in Mexico as a vehicle for rural development, believing that a better understanding of the internal logic of peasant production might facilitate an alternative series of policy measures. The weaknesses of the ‘campesinista’ position are explored, and doubts expressed about the viability of the populist stance as long as Mexico has the option of importing basic foodcrops.     

Specific Purpose Programs in Human Services and Health: Moving from an Input to an Output and Outcome Focus

The content and control mechanisms of specific purpose programs are regularly under review, currently through processes associated with the Council of Australian Governments (COAG), with most proposals for reform in this area arguing for a shift to a focus on outputs or outcomes. This article reviews the place and role of specific purpose programs in the human services and health field, and identifies four issues which need to be addressed as part of any refocus onto outputs and outcomes. The four issues are: specification of objectives; measurement of outputs and/or outcomes; mechanisms for ensuring accountability to consumers; and systems of sanctions and rewards.     

Patterns of childhood poverty: New challenges for policy

Poverty takes many forms. Using data from the U.S. Panel Study of Income Dynamics, this article (1) distinguishes different kinds of childhood poverty, defined in terms of the spacing, severity, and duration of spells; and (2) establishes the extent and distribution of childhood poverty, employing new measures that take into account both duration and severity. Some strategies for targeting assistance on particular forms of poverty are briefly considered.
