AbstractAccording to a range of authors and popular commentators, the post-Fordist socioeconomic order has produced a new category of female labourer, the ‘female principal breadwinner’. This article opens out this category of worker to critical scrutiny. We suggest that while the very idea of the female principal breadwinner is open to all manner of existing lines of feminist critique, beyond this it forces a confrontation with a number of issues vital to feminist analyses of transformations to women's labour—both waged and unwaged—in contemporary financialised post-Fordism. We pursue two issues in particular. First, transformations to the labour of social reproduction—including transformations to the measurement and valuation of domestic labour—and second, the financialisation (and shifting capacities) of wages specifically and money more generally. We suggest that if transformations to women's labour are to be fully grasped and understood feminist theory must renew and rethink its analyses of domestic labour, wages and money. 相似文献

Abstract: A significant amount of research has been conducted into the use of stable isotopes to assist in determining the origin of various materials. The research conducted in the forensic field shows the potential of isotope ratio mass spectrometry (IRMS) to provide a level of discrimination not achievable utilizing traditional forensic techniques. Despite the research there have been few, if any, publications addressing the validation and measurement uncertainty of the technique for forensic applications. This study, the first in a planned series, presents validation data for the measurement of bulk nitrogen isotope ratios in ammonium nitrate (AN) using the DELTAplusXP (Thermo Finnigan) IRMS instrument equipped with a ConFlo III interface and FlashEA? 1112 elemental analyzer (EA). Appropriate laboratory standards, analytical methods and correction calculations were developed and evaluated. A validation protocol was developed in line with the guidelines provided by the National Association of Testing Authorities, Australia (NATA). Performance characteristics including: accuracy, precision/repeatability, reproducibility/ruggedness, robustness, linear range, and measurement uncertainty were evaluated for the measurement of nitrogen isotope ratios in AN. AN (99.5%) and ammonium thiocyanate (99.99+%) were determined to be the most suitable laboratory standards and were calibrated against international standards (certified reference materials). All performance characteristics were within an acceptable range when potential uncertainties, including the manufacturer’s uncertainty of the technique and standards, were taken into account. The experiments described in this article could be used as a model for validation of other instruments for similar purposes. Later studies in this series will address the more general issue of demonstrating that the IRMS technique is scientifically sound and fit‐for‐purpose in the forensic explosives analysis field. 相似文献

Two divergent perspectives have been articulated in the literature regarding the effect that an unbalanced sex ratio is speculated to have on male-on-female intimate partner violence. Evolutionary psychology proffers that a high sex ratio (i.e., more men than women in the population) propagates competition among males for female mates. This competition for female mates is thought to engender sexual jealousy among men, which in turn results in male-on-female intimate partner violence. In contrast, the Guttentag and Secord thesis argues that a high sex ratio acts to attenuate rather than amplify male-on-female intimate partner violence because the relatively small number of women in the population makes them more highly valued and respected by men. Using data culled from the Federal Bureau of Investigation's National Incident-Based Reporting System (NIBRS) and the Census, we investigate the relationship between the sex ratio and male-on-female intimate partner violence. We define male-on-female intimate partner violence as violence occurring within a marriage or boyfriend/girlfriend type relationship. Multivariate regression results furnish evidence supporting evolutionary psychology by demonstrating that a high sex ratio increases male-on-female intimate partner violence. Results also show that male-on-female intimate partner violence is higher in cities where more women work. Such a finding further buttresses the logic associated with evolutionary psychology because participation in the workforce is theorized to afford a woman a greater opportunity to meet and interact with men other than her husband or boyfriend. 相似文献

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. 相似文献

The practice of allocating scarce organs in medicine is an ethical minefield. Due to the organ shortage, organ procurement agencies in both the United Kingdom and the United States are placed in the unenviable position of having to choose a limited number of patients to compete equally for life-saving treatment. They do this by composing multidisciplinary transplant teams, which must evaluate transplant candidates and their complex range of personal, medical, environmental, psychiatric and financial characteristics. During the candidate assessment process, such teams may often be torn between their moral duty to save those who are most in need, considerations of efficiency, and the battle against forming moral judgments about particular candidates. Several ethical approaches can be adopted by transplant teams during the decision-making process, but do these ideologies provide adequate justification for their sometimes controversial decisions? This article provides a detailed examination of the ethical principles available to transplant teams in the United Kingdom and the United States, and the effect that these principles have on assessment procedures, organ allocation protocols, transplant candidates and their prospects. 相似文献

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. 相似文献

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. 相似文献
