Mais n'est-ce pas " sexuel "? Le lapsus derrière le regard ethnographique

RÉSUMÉN'est-ce pas " sexuel " ? Le lapsus derrière le regard ethnographiqueDans cet article, j'applique à l'étude des rituels des chamanes coréennes certaines des préoccupations et des mises en garde exprimées dans de récents écrits sur le sexe et le genre. Mon but est d'illustrer un problème spécifique de l'interprétation ethnographique et de lancer un appel à la précision, de crainte qu'un étiquetage hâtif des rituels, ou des éléments de leur exécution, comme « sexuels » ou « erotiques » n'exclue des interprétations plus complexes et plus respectueuses de leur contexte. Je commence par une description de quelques-unes des façons dont mes propres écrits sur les chamanes coréennes ont été interprétés à mauvais escient.Je m'intéresse plus directement aux lectures que l'auditoire occidental fait subir au texte ethnographique sur le genre, mais j'examinerai aussi les représentations de la sexualité des chamanes dans la culture populaire coréenne et les discours des chamanes sur la sexualité des hommes dans le texte d'un rituel improvisé. Cette entreprise se distingue de celle qui consiste à attribuer à l'ensemble des activités des chamanes un caractère foncièrement « sexuel ».Mots clés : Kendall. chamanisme. danse, sexualité, méthode. CoréeABSTRACTBut Isn't It " Sexual " ? The Freudian Slip beneath the Ethnographie GazeIn this paper. I apply some of the concerns and cautions expressed in recent writing about sex and gender to Korean shaman rituals as a specifie problem of ethnographie interpretation and to make a plea for precision lest a hasty labeling of ritual or performance elements as " sexual " or " erotic " foreclose more complex and context-specific interpretations. I begin with a description of some of the ways in which my own writing on Korean shamans has been misinterpreted.While most immediately concerned with the readings that Western audience can impose upon a gendered ethnographie text. I shall also consider représentations of shamans" sexuality in Korean popular culture and shaman discourses about the sexuality of men in an improvisational ritual text. This enterprise is distinct from that of characterizing the sum of shamans' activities as innately " sexual ".Key words : Kendall. shamanism. dance. sexuality. method. Kore

‘Dominant ethnicity’ and the ‘ethnic-civic’ dichotomy in the work of A. D. Smith

This article considers the way in which the work of Anthony Smith has helped to structure debates surrounding the role of ethnicity in present-day nations. Two major lines of enquiry are evident here. First, the contemporary role of dominant ethnic groups within 'their' nations and second, the interplay between ethnic and civic elements in nationalist argument. The two processes are related, but maintain elements of distinctiveness. Smith's major contribution to the dominant ethnicity debate has been to disembed ethnicity from the ideologically-charged and/or anglo-centric discourse of ethnic relations and to place it in historical context, thereby opening up space for dominant group ethnicity to be considered as a distinct phenomenon. This said, Smith's work does not adequately account for the vicissitudes of dominant ethnicity in the contemporary West. Building on the classical works of Hans Kohn and Friedrich Meinecke, Anthony Smith has also made a seminal contribution to the debate on civic and ethnic forms of national identity and nationalist ideology. As well as freeing this debate from the strong normative overtones which it has often carried, he has continued to insist that the terms civic and ethnic should be treated as an ideal-typical distinction rather than a scheme of classification

Injury Risk Perception of Commercial Dungeness Crab Fishermen

The Fishermen Led Injury Prevention Program is the first and only research focused on non-fatal injury prevention among commercial fishermen. • No fishermen reported that they had zero chance of injury, regardless of injuries sustained in career and/or in the past year. • Fishermen who have sustained an injury in their career and/or in the past year, have a higher perception of injury risk. • There is no connection between a fisherman’s history with injury and the amount they worry about sustaining an injury.• Commercial fishing is one of the most dangerous professions in the United States. • Between 2002-2014 Dungeness crab fishermen had 209 fatalities per 100,000 full-time equivalent workers. • 405 surveys were collected by community researchers before the 2015-2016 Dungeness crab season. • We examine here the association of injury and risk perception

Brain multiplexes reveal morphological connectional biomarkers fingerprinting late brain dementia states

Accurate diagnosis of mild cognitive impairment (MCI) before conversion to Alzheimer’s disease (AD) is invaluable for patient treatment. Many works showed that MCI and AD affect functional and structural connections between brain regions as well as the shape of cortical regions. However, ‘shape connections’ between brain regions are rarely investigated -e.g., how morphological attributes such as cortical thickness and sulcal depth of a specific brain region change in relation to morphological attributes in other regions. To fill this gap, we unprecedentedly design morphological brain multiplexes for late MCI/AD classification. Specifically, we use structural T1-w MRI to define morphological brain networks, each quantifying similarity in morphology between different cortical regions for a specific cortical attribute. Then, we define a brain multiplex where each intra-layer represents the morphological connectivity network of a specific cortical attribute, and each inter-layer encodes the similarity between two consecutive intra-layers. A significant performance gain is achieved when using the multiplex architecture in comparison to other conventional network analysis architectures. We also leverage this architecture to discover morphological connectional biomarkers fingerprinting the difference between late MCI and AD stages, which included the right entorhinal cortex and right caudal middle frontal gyrus

Multimodal and Multiscale Deep Neural Networks for the Early Diagnosis of Alzheimer’s Disease using structural MR and FDG-PET images

Alzheimer’s Disease (AD) is a progressive neurodegenerative disease where biomarkers for disease based on pathophysiology may be able to provide objective measures for disease diagnosis and staging. Neuroimaging scans acquired from MRI and metabolism images obtained by FDG-PET provide in-vivo measurements of structure and function (glucose metabolism) in a living brain. It is hypothesized that combining multiple different image modalities providing complementary information could help improve early diagnosis of AD. In this paper, we propose a novel deep-learning-based framework to discriminate individuals with AD utilizing a multimodal and multiscale deep neural network. Our method delivers 82.4% accuracy in identifying the individuals with mild cognitive impairment (MCI) who will convert to AD at 3 years prior to conversion (86.4% combined accuracy for conversion within 1–3 years), a 94.23% sensitivity in classifying individuals with clinical diagnosis of probable AD, and a 86.3% specificity in classifying non-demented controls improving upon results in published literature

The impact of PICALM genetic variations on reserve capacity of posterior cingulate in AD continuum

Phosphatidylinositolbinding clathrin assembly protein (PICALM) gene is one novel genetic player associated with late-onset Alzheimer’s disease (LOAD), based on recent genome wide association studies (GWAS). However, how it affects AD occurrence is still unknown. Brain reserve hypothesis highlights the tolerant capacities of brain as a passive means to fight against neurodegenerations. Here, we took the baseline volume and/or thickness of LOAD-associated brain regions as proxies of brain reserve capacities and investigated whether PICALM genetic variations can influence the baseline reserve capacities and the longitudinal atrophy rate of these specific regions using data from Alzheimer’s Disease Neuroimaging Initiative (ADNI) dataset. In mixed population, we found that brain region significantly affected by PICALM genetic variations was majorly restricted to posterior cingulate. In sub-population analysis, we found that one PICALM variation (C allele of rs642949) was associated with larger baseline thickness of posterior cingulate in health. We found seven variations in health and two variations (rs543293 and rs592297) in individuals with mild cognitive impairment were associated with slower atrophy rate of posterior cingulate. Our study provided preliminary evidences supporting that PICALM variations render protections by facilitating reserve capacities of posterior cingulate in non-demented elderly

Early role of vascular dysregulation on late-onset Alzheimer's disease based on multifactorial data-driven analysis

Multifactorial mechanisms underlying late-onset Alzheimer's disease (LOAD) are poorly characterized from an integrative perspective. Here spatiotemporal alterations in brain amyloid-β deposition, metabolism, vascular, functional activity at rest, structural properties, cognitive integrity and peripheral proteins levels are characterized in relation to LOAD progression. We analyse over 7,700 brain images and tens of plasma and cerebrospinal fluid biomarkers from the Alzheimer's Disease Neuroimaging Initiative (ADNI). Through a multifactorial data-driven analysis, we obtain dynamic LOAD–abnormality indices for all biomarkers, and a tentative temporal ordering of disease progression. Imaging results suggest that intra-brain vascular dysregulation is an early pathological event during disease development. Cognitive decline is noticeable from initial LOAD stages, suggesting early memory deficit associated with the primary disease factors. High abnormality levels are also observed for specific proteins associated with the vascular system's integrity. Although still subjected to the sensitivity of the algorithms and biomarkers employed, our results might contribute to the development of preventive therapeutic interventions
