    An issue central to the history oftextiles is how and with what consequences the cultural significance of textiles has changed. In this paper I will use an anthropological perspective to argue that the cultural or symbolic properties of textiles have played an important role in the transformation of western societies from the sixteenth century onwards. This argument will be made in three parts: first, that the western modernity was driven just as much by a "consumer revolution" as an industrial one; second, that the consumer revolution was driven by the effort to invest material culture and clothing with new cultural meanings; and finally, that this process of meaning investment was driven by changing definitions of social groups and the individual. The paper will summarize past research that bears on this question and suggest new avenues of research that issue from it. RĂ©sumĂ© L'intĂ©rĂȘt que prĂ©sente l'histoire des textiles tient notamment Ă  la façon dont a Ă©voluĂ© la signification culturelle des textiles et Ă  ses consĂ©quences. L'auteur se propose de montrer ici, dans une perspective anthropologique, le rĂŽle important que les propriĂ©tĂ©s culturelles ou symboliques des textiles ont jouĂ© dans la transformation des sociĂ©tĂ©s occidentales depuis le XVIe siĂšcle. Trois Ă©tapes mĂšneront Ă  cette conclusion. Nous verrons en premier lieu que la modernitĂ© occidentale a Ă©tĂ© le fait tout autant d'une rĂ©volution de la consommation que d'une rĂ©volution industrielle; deuxiĂšmement, que cette rĂ©volution de la consommation s'est produite sous la poussĂ©e de l'effort visant Ă  attribuer de nouvelles significations culturelles Ă  la culture matĂ©rielle et Ă  l'habillement; enfin, que le processus d'attribution de nouvelles significations dĂ©coule de nouvelles dĂ©finitions des groupes sociaux et de l'individu. L'article rĂ©sume les recherches existantes sur la question et propose de nouvelles avenues de recherche Ă  explorer pour y donner suite

    Systematics, Ecology, and Social Biology of the Musk Duck (Biziura Lobata) of Australia.

    Musk Ducks (Biziura lobata) exhibit a number of unusual morphological and behavioral traits. The most notable of these include: greatly abducted hind-limbs for underwater swimming efficiency, extreme sexual size dimorphism and pronounced structural dimorphism, lek display activity, elaborate sexual display repertoires, and the distinctly non-waterfowl-like trait of provisioning young with all their food from the time of hatch until fledging. Despite such peculiarities and obvious theoretical potential in the areas of comparative morphology, sexual selection, and brood ecology, few studies of Musk Ducks have been undertaken, and those to date have been either small in scope and design, or focused on captive birds. I present here an investigation of historical, ecological, and social aspects of Musk Duck biology that hitherto have gone unstudied or generally remained unnoticed. Based on phylogenetic analyses of mtDNA sequences of the cytochrome b gene, I conclude that Musk Ducks are not close relatives of other stifftail ducks (e.g., Nomonyx, Oxyura) as previously surmised, but rather, a more distant, independently derived lineage in which hind-limb morphology and other correlated diving adaptations have evolved convergently. Multivariate analyses of sixteen anatomical measurements, likewise, suggest that sexual selection has played an important role in determining overall patterns of male morphometric variation. Niche divergence, on the other hand, can not be ruled out and might also be a viable explanation of observed levels of sexual size dimorphism. Time-budget and activity-pattern information generally support these conclusions, revealing pronounced differences between sexes, in addition to large scale patterns of spatial and temporal variation. Acoustic analyses of sexual advertising displays reveal fixed cultural differences between eastern and western populations consistent with Bassian faunal elements, in addition to previously undescribed variation within populations. Comparisons with immature wild birds and captive adults also indicate that dialects are learned

    Draft genome sequences of seven isolates of Phytophthora ramorum EU2 from Northern Ireland

    Get PDF
    Here we present draft-quality genome sequence assemblies for the oomycete Phytophthora ramorum genetic lineage EU2. We sequenced genomes of seven isolates collected in Northern Ireland between 2010 and 2012. Multiple genome sequences from P. ramorum EU2 will be valuable for identifying genetic variation within the clonal lineage that can be useful for tracking its spread

    The neural mechanisms of mindfulness-based pain relief: a functional magnetic resonance imaging-based review and primer.

    Get PDF
    The advent of neuroimaging methodologies, such as functional magnetic resonance imaging (fMRI), has significantly advanced our understanding of the neurophysiological processes supporting a wide spectrum of mind-body approaches to treat pain. A promising self-regulatory practice, mindfulness meditation, reliably alleviates experimentally induced and clinical pain. Yet, the neural mechanisms supporting mindfulness-based pain relief remain poorly characterized. The present review delineates evidence from a spectrum of fMRI studies showing that the neural mechanisms supporting mindfulness-induced pain attenuation differ across varying levels of meditative experience. After brief mindfulness-based mental training (ie, less than 10 hours of practice), mindfulness-based pain relief is associated with higher order (orbitofrontal cortex and rostral anterior cingulate cortex) regulation of low-level nociceptive neural targets (thalamus and primary somatosensory cortex), suggesting an engagement of unique, reappraisal mechanisms. By contrast, mindfulness-based pain relief after extensive training (greater than 1000 hours of practice) is associated with deactivation of prefrontal and greater activation of somatosensory cortical regions, demonstrating an ability to reduce appraisals of arising sensory events. We also describe recent findings showing that higher levels of dispositional mindfulness, in meditation-naĂŻve individuals, are associated with lower pain and greater deactivation of the posterior cingulate cortex, a neural mechanism implicated in self-referential processes. A brief fMRI primer is presented describing appropriate steps and considerations to conduct studies combining mindfulness, pain, and fMRI. We postulate that the identification of the active analgesic neural substrates involved in mindfulness can be used to inform the development and optimization of behavioral therapies to specifically target pain, an important consideration for the ongoing opioid and chronic pain epidemic

    Gene Flow and Hybridization between Numerically Imbalanced Populations of Two Duck Species in the Falkland Islands

    Interspecific hybridization is common in plants and animals, particularly in waterfowl (Anatidae). One factor shown to contribute to hybridization is restricted mate choice, which can occur when two species occur in sympatry but one is rare. The Hubbs principle, or “desperation hypothesis,” states that under such circumstances the rarer species is more likely to mate with heterospecifics. Here we report interspecific hybridization between two waterfowl species that coexist in broad sympatry and mixed flocks throughout southern South America. Speckled teal (Anas flavirostris) and yellow-billed pintails (Anas georgica) are abundant in continental South America, but in the Falkland Islands speckled teal outnumber yellow-billed pintails approximately ten to one. Using eight genetic loci (mtDNA and 7 nuclear introns) coupled with Bayesian assignment tests and relatedness analysis, we identified a speckled teal x yellow-billed pintail F1 hybrid female and her duckling sired by a male speckled teal. Although our sample in the Falkland Islands was small, we failed to identify unequivocal evidence of hybridization or introgression in a much larger sample from Argentina using a three-population “isolation with migration” coalescent analysis. While additional data are needed to determine if this event in the Falkland Islands was a rare singular occurrence, our results provide further support for the “desperation hypothesis,” which states that scarcity in one population and abundance of another will often lead to hybridization

    Misguided Optimism Among College Student Smokers: Leveraging Their Quit-Smoking Strategies for Smoking Cessation Campaigns

    Get PDF
    College student smokers are a unique group who typically plan to quit smoking by the time they graduate, but few succeed and those who do require multiple attempts. This study examines the strategies of college student participants who successfully quit smoking. They tell a story of trial and error in achieving their goal—one that is more likely to end in another failed attempt than a successful effort unless they learn from past mistakes. Their stories not only show misplaced optimism for quitting but also ineffective smoking-cessation efforts

    Linked lives: Gender, family relations and recurrent care proceedings in England

    Get PDF
    In the wake of a “national care crisis” in England, an increasing number of parents return to the family court as repeat respondents in care proceedings and lose successive children from their care. Despite considerable progress in understanding the trends and patterns of mothers' (re)appearances in care proceedings, knowledge of fathers and of parents' family relationships in recurrent care proceedings remains very limited. Whilst such relationships are fundamentally at stake in care proceedings, they remain largely unexplored. Analyzing population-level administrative data from the family courts in England (2007/08–2017/18, N = 25,457), we have, for the first time, uncovered a five-fold typology of family relations between mothers, fathers and children as they navigated repeated sets of care proceedings. We show that each identified profile is characterized by parents' gender as well as distinctive life-course positions of the parents and children. Our findings show that a substantial number of fathers are ‘visible’ in care proceedings, and that the majority of those that return to court do so with the same partners and children, as part of either a recurrent family or recurrent couple. Mothers' recurrence is characterized by their re-partnering experiences and lone appearances before the court. The results underscore the value of applying a relational approach in social work research and practice, to build a fuller picture of recurrent care proceedings. This research provides new evidence to inform the development of holistic, gender-sensitive and father-inclusive services in the English family justice system
