This review chronicles the characteristics of deliberate and accidental mass poisonings that occurred in World Wars I and II, in Bhopal, and in other historical cases up to and including modern wars. It also considers approaches to the investigation of such cases from the medicolegal as well as general standpoints.  相似文献

Despite some understanding of general correlates and possible antecedents to intimate partner violence (IPV) within the Christian community, the impact of religious and spiritual factors tends to be confounded by other factors and is often misjudged. Archival data from Wave III of the National Longitudinal Study of Adolescent Health (Add Health) were used to examine the impact of nine religious and spiritual factors on the probability of IPV perpetration by males, aged 18 to 26, who nominally classified themselves as Catholic, Protestant, or Christian. Logistic regression results indicated that IPV perpetration could not be adequately predicted from the religious and spiritual factors. Given the geographic breadth and the size of the Add Health sample, no finding of a predictive model for Christian male-perpetrated IPV challenges the paradigm that religious and spiritual factors should be overtly addressed in faith-based batterers’ programs targeting young adult males.  相似文献

This paper examines the historical development of the Australian welfare state with a view to identifying the role that Australia's federal constitutional arrangements have played in shaping that development. Theoretical paradigms have been unanimous in their prognoses: that federal states are likely to be slow in developing welfare state programmes and typically spend less on them than unitary states. But recently it has been argued that federal institutions may have a “ratchet effect” of slowing down the pace of change, irrespective of its direction. The purpose of this chronological account of significant stages in the development of the Australian welfare state is to use the unfolding of historical events — far too rich in nuance and detail to be captured in quantitative modelling — as a test‐bed for establishing whether, and, if so, to what extent, federalism has impacted on the trajectory of Australian welfare state development.  相似文献

The most ferocious debates are about whether the United States should be described as imperial, but in practice other countries also try to influence other countries’ domestic policies, to propagate their visions, to exert power and to stabilize areas beyond their borders that are perceived as a source of threats. While in the 1990s the winners of globalization were seen as small open states, since the turn of the millennium big powers appear to be gaining because of their ability to project political power: the United States, but also China, Russia, India, and Brazil. This makes for a greater instability and leads to the formulation of theories of realism or neo-realism. The essay concludes with an examination of alternatives to empire and the neo-imperial vision, in particular the importance of elaboration of common or shared values in helping to build a safer and more peaceful international order.  相似文献

Bloodstains were made with 200 microliters blood on each of 11 different common substrates to examine the effect of the stain carrier on the amount and quality of DNA recoverable. High-molecular-weight DNA was extracted from all samples after 2 days. The yield of DNA from each sample varied considerably, not only between the different stain carriers but also within a given category. With a DNA yield of up to 10 micrograms, paper, glass, nylon, wood, smooth leather and wool gave the best results, followed by blue denim and wallpaper (up to 6 micrograms), cotton fabric and carpeting (up to 4 micrograms) and suede (up to 2 micrograms). For several stain carriers the DNA-containing solution was contaminated by chemical substances, which in the case of the blue denim, suede, and carpet samples inhibited the digestion of the DNA with restriction enzymes and prevented DNA typing. The different textures of the stain carriers tested and (as for varying yields on the same carrier) the differing degree of loss of DNA during extraction and the physiological variation in the number of leukocytes in human blood are discussed as possible reasons for the wide range of variation in the amounts of DNA it was possible to extract.  相似文献
