Le rôle de la culture en épidémiologie psychiatrique : examen de la recherche sur la santé mentale des Latino-Américains

En épidémiologie psychiatrique, la culture est souvent traitée, de deux choses Tune, ou comme une variable déconcertante qu'il faut contrôler, ou comme l'explication de résultats inattendus. Quand elle est présentée comme explication, on pousse généralement assez peu l'examen de l'influence qu'elle exerce sur les réponses à l'entrevue psychiatrique. J'avance ici que la culture exerce une influence centrale dans les entrevues, d'au moins trois façons: elle détermine la façon dont les gens répondent à l'entrevue; elle influence l'évaluation des items portant sur des symptômes spécifiques, et les catégories culturelles se retrouvent enchâssées dans les réponses à l'entrevue. Passant en revue la I recherche menée sur la santé mentale des populations latino-américaines, j'examine le rôle joué par les catégories culturelles dans les réponses aux études d'épidémiologie psychiatrique, et j'en esquisse une approche de recherche alternative, pour explorer simultanément des catégories du diagnostic psychiatrique et des expressions culturelles de détresse.In psychiatric epidemiology, culture has often been treated in one of two ways : as a confounding variable to be controlled or as an explanation for unexpected findings. In cases where culture is presented as an explanation, there is often little detailed examination of how culture shapes responses to psychiatric interviews. In this paper, I will argue that culture plays a central role in influencing responses to psychiatric interviews in at least three ways: culture affects the way people respond to psychiatric interviews; culture influences the valuation of specific symptom items; and cultural categories are embedded in responses to psychiatric interviews. Through a review of research on the mental health of Latino populations, I will examine the roles of cultural categories in shaping responses to psychiatric epidemiology studies and will outline an alternative research approach to simultaneously exploring psychiatric diagnostic categories and cultural idioms of distress

Clinical encounters with immigrants: What matters for U.S. psychiatrists.

About 3.2 percent of the population across the globe are migrants. Today, unprecedented numbers of people are relocating in the U.S. and more than ever, psychiatrists find themselves caring for immigrant patients. International migration is a multilayered issue that often has implications for the mental health of migrants. Thus, there is an increasing interest in understanding how the different factors associated with migration processes affect the mental health outcomes of immigrants. We group these factors into three categories: immigrant process, clinical encounter, and mental health services. When possible, we incorporate a gendered and life span perspective and suggest avenues for including what we know into the care of children, adults, and elderly psychiatric patients with immigrant backgrounds. We pay special attention to the immigrant paradox literature, which explains why some immigrants are healthier when they start their journey, and why their mental health deteriorates as they live longer in the host societies. We aim at providing psychiatrists an understanding of what to ask, assess, and consider when caring for patients who are international migrants

Acculturation and Its Discontents: A Case for Bringing Anthropology Back into the Conversation

Anthropologists’ contribution to the study of cultural change is urgent in light of the increasing number of people of different backgrounds who are migrating around the globe and settling in new communities, and the opportunities and challenges that come along with that process. By examining the anthropological literature on acculturation going back to the 1936 Memorandum by Redfield, Linton and Herskovits, this paper reviews and assesses the discipline’s perspective on acculturation, and lays out the case for why it is critical for anthropologists to re-engage the concept. Although other disciplines, particularly psychology and sociology, have dominated the field of acculturation research more recently, they mostly have done so with a narrow focus. While it is important to acknowledge the pitfalls of anthropology’s past study of acculturation, there are important features of the acculturation construct that continue to be relevant. Among these are the study of acculturation as a process that is multidimensional; the investigation of how different kinds of power affect the acculturation process; the impacts of attitudes, actions and policies of the receiving group on how acculturation proceeds; the role of “real history” in understanding processes of acculturation; and the global perspective on these processes. We suggest ways in which anthropologists can reignite the field of acculturation research by engaging with Redfield, Linton and Herskovits’ framework and subsequent anthropological literature

The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

Fusarium: more than a node or a foot-shaped basal cell

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an alternate hypothesis, namely a very broad concept of the genus Fusarium was proposed. In doing so, however, a significant body of data that supports distinct genera in Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA phylogeny based on 19 orthologous protein-coding genes was presented to support a very broad concept of Fusarium at the F1 node in Nectriaceae. Here, we demonstrate that re-analyses of this dataset show that all 19 genes support the F3 node that represents Fusarium sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone of the phylogeny is resolved by the concatenated alignment, but only six of the 19 genes fully support the F1 node, representing the broad circumscription of Fusarium. Furthermore, a re-analysis of the concatenated dataset revealed alternate topologies in different phylogenetic algorithms, highlighting the deep divergence and unresolved placement of various Nectriaceae lineages proposed as members of Fusarium. Species of Fusarium s. str. are characterised by Gibberella sexual morphs, asexual morphs with thin- or thick-walled macroconidia that have variously shaped apical and basal cells, and trichothecene mycotoxin production, which separates them from other fusarioid genera. Here we show that the Wollenweber concept of Fusarium presently accounts for 20 segregate genera with clear-cut synapomorphic traits, and that fusarioid macroconidia represent a character that has been gained or lost multiple times throughout Nectriaceae. Thus, the very broad circumscription of Fusarium is blurry and without apparent synapomorphies, and does not include all genera with fusarium-like macroconidia, which are spread throughout Nectriaceae (e.g., Cosmosporella, Macroconia, Microcera). In this study four new genera are introduced, along with 18 new species and 16 new combinations. These names convey information about relationships, morphology, and ecological preference that would otherwise be lost in a broader definition of Fusarium. To assist users to correctly identify fusarioid genera and species, we introduce a new online identification database, Fusarioid-ID, accessible at www.fusarium.org. The database comprises partial sequences from multiple genes commonly used to identify fusarioid taxa (act1, CaM, his3, rpb1, rpb2, tef1, tub2, ITS, and LSU). In this paper, we also present a nomenclator of names that have been introduced in Fusarium up to January 2021 as well as their current status, types, and diagnostic DNA barcode data. In this study, researchers from 46 countries, representing taxonomists, plant pathologists, medical mycologists, quarantine officials, regulatory agencies, and students, strongly support the application and use of a more precisely delimited Fusarium (= Gibberella) concept to accommodate taxa from the robust monophyletic node F3 on the basis of a well-defined and unique combination of morphological and biochemical features. This F3 node includes, among others, species of the F. fujikuroi, F. incarnatum-equiseti, F. oxysporum, and F. sambucinum species complexes, but not species of Bisifusarium [F. dimerum species complex (SC)], Cyanonectria (F. buxicola SC), Geejayessia (F. staphyleae SC), Neocosmospora (F. solani SC) or Rectifusarium (F. ventricosum SC). The present study represents the first step to generating a new online monograph of Fusarium and allied fusarioid genera (www.fusarium.org)

The ALICE experiment at the CERN LHC

ALICE (A Large Ion Collider Experiment) is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model. It is designed to address the physics of strongly interacting matter and the quark-gluon plasma at extreme values of energy density and temperature in nucleus-nucleus collisions. Besides running with Pb ions, the physics programme includes collisions with lighter ions, lower energy running and dedicated proton-nucleus runs. ALICE will also take data with proton beams at the top LHC energy to collect reference data for the heavy-ion programme and to address several QCD topics for which ALICE is complementary to the other LHC detectors. The ALICE detector has been built by a collaboration including currently over 1000 physicists and engineers from 105 Institutes in 30 countries. Its overall dimensions are 161626 m3 with a total weight of approximately 10 000 t. The experiment consists of 18 different detector systems each with its own specific technology choice and design constraints, driven both by the physics requirements and the experimental conditions expected at LHC. The most stringent design constraint is to cope with the extreme particle multiplicity anticipated in central Pb-Pb collisions. The different subsystems were optimized to provide high-momentum resolution as well as excellent Particle Identification (PID) over a broad range in momentum, up to the highest multiplicities predicted for LHC. This will allow for comprehensive studies of hadrons, electrons, muons, and photons produced in the collision of heavy nuclei. Most detector systems are scheduled to be installed and ready for data taking by mid-2008 when the LHC is scheduled to start operation, with the exception of parts of the Photon Spectrometer (PHOS), Transition Radiation Detector (TRD) and Electro Magnetic Calorimeter (EMCal). These detectors will be completed for the high-luminosity ion run expected in 2010. This paper describes in detail the detector components as installed for the first data taking in the summer of 2008

Mind, body, and culture: Somatization among Hispanics

In this analysis we employ the recently released Hispanic Health and Nutrition Examination Survey (Hispanic HANES) to investigate the issue of somatization among Mexican Americans and Puerto Ricans. In order to do so, we use the physician's assessment as a control, and examine the association between depressive affect and self-perceptions of health for individuals with similar evaluated health levels. The data reveal rather dramatic discrepancies between individual's assessments of their own health and physicians' evaluations. In addition, the data reveal that, net of the physician's evaluation, individuals' assessments of their overall health status are significantly influenced by their affective states. The data also reveal a strong effect of language of interview on self-assessments of health and depressive affect.somatization Hispanic depression physical symptoms
