Abstract: Our objective is to document the recovery of DNA from the spinal cord or surrounding dura mater in 11 cases of severely burned human remains. Radiographs established that portions of charred tissue contained spine segments. Multidetector computed tomography (MDCT) revealed that each spine specimen contained an intact spinal cord remnant. A full DNA profile was obtained from seven specimens using spinal cord dura mater in six specimens and spinal cord medulla in one specimen. A partial profile was obtained from four specimens (spinal cord dura mater, 2; spinal cord medulla, 2). Bone and muscle surrounding the spinal cord appear to insulate nucleic acid containing tissue from critical thermal degradation. The spinal cord, which is easily identified by MDCT examination of remains and easily recovered at the postmortem examination, can be a source of DNA with extraction yields comparable with other tissue sources. Specimens of dura mater are preferable as processing time is faster than bone. 相似文献

Our paper analyses the modalities according to which a large European university collaborates with firms by exploring its
relational portfolio. We address this issue by exploiting a database that lists more than 1,000 firms having collaborated
with the University Louis Pasteur (ULP) between 1990 and 2002. We first observe the relative importance of four collaborative
channels (private contracts, European contracts, co-publications, co-inventions) across the whole population of firms. Second,
using a multi-correspondence analysis, we derive a typology of collaborative patterns which underline the discriminating features
of the frequency of interactions, of the exclusive versus open character of the relationships and of the nature of the collaborative
channels. Four coherent classes emerge from particular combinations of these relational characteristics. Finally, using multinomial
logit estimation, we show how this diversity of partnerships is connected to some individual attributes of the firms: size,
status, sector and location.

Though many individuals are aware of the need to address environmental concerns, fewer are willing to pay for climate action or think the environment should be a priority for government spending. One compelling reason is that they prioritize using scarce resources to address immediate material concerns. This is particularly likely for individuals facing absolute material scarcity or for those who think they are relatively economically worse off, especially in contexts characterized by rapid transformation and volatility in the levels and quality of social welfare provision. To test these expectations, we analyze survey data from formerly Communist economies, which today find themselves with vastly different fortunes. Empirical findings suggest that absolute and relative material scarcity affect opinions regarding government spending on, and the willingness to pay more for, environmental action. However, willingness to pay more for government public services, inclusive of anti-poverty initiatives, has an impact on willingness to pay more for climate action, but in counter-intuitive ways. Overall, the results appear to suggest that explicitly addressing and relating individual living standards and inequality with environmental concerns may expand support for climate action. 相似文献

In the 1970s, social psychologists conducted numerous studies analyzing physical appearance as a social variable. More recent
studies in the social sciences appear to have abandoned this topic as unimportant; in any case, very few social scientific
studies have been found that incorporate a measure of attractiveness into their analyses. The present study seeks to revive
the emphasis on physical attractiveness as a social variable by testing the relationship between crime severity and physical
attractiveness, i.e., by presenting evidence to suggest that physically unattractive men commit more serious offenses.

This paper illustrates how Sisterhood and After: The Women's Liberation Oral History Project has approached difference and diversity within the history of women's movements. I argue that the terms ‘difference and diversity’ cannot do justice to histories of black women unless they are used to highlight the impact of race on black women's experiences in women's movements. Furthermore given the widespread acknowledgment that there was tension in the British women's liberation movement over the marginalization, exclusion and racism faced by black and Asian women, the project sought to ensure that black and Asian women's varied experiences as campaigners were explored and we also asked our white interviewees about race. I show how the in-depth nature of the life history interview method holds the possibility for greater reflection on these vital and often unsettling issues in feminism's history. 相似文献

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships. 相似文献

The Group of Eight Countries (G8) launched the New Alliance for Food Security and Nutrition to improve nutritional outcomes through private sector involvement in agricultural development. The accession of Malawi to the Alliance reveals the assumptions behind the intervention. We show that while the New Alliance may seem to have little to do with nutrition, its emergence as a frame for the privatization of food and agriculture has been decades in the making, and is best understood as an outcome of a project of nutritionism. To highlight the failings of the approach, we present findings from the Soils, Food and Healthy Communities Initiative in northern Malawi, which has demonstrated success in combatting malnutrition through a combination of agroecological farming practices, community mobilization, women's empowerment and changes in intrahousehold gender dynamics. Contrasting a political economic analysis of the New Alliance alongside that of the Soils, Food and Healthy Communities Initiative shows the difference between a concern with the gendered social context of malnutrition, and nutritionism. We conclude with an analysis of the ways that nutrition can play a part in interventions that are inimical, or conducive, to freedom. 相似文献
