The local and filmed accountability of sensorial practices: The intersubjectivity of touch as an interactional achievement

This paper contributes to a multimodal EMCA approach to sensoriality and to a reflection about how video can support it. First, it discusses how the intersubjectivity and accountability of sensorial practices are locally and endogenously achieved by and for the participants. This accountability is implemented through various multimodal resources, which make sensorial practices accessible for the co-participants. Second, it shows how the visual, verbal and sometimes co-tactile orientations of the participants are also the very basis on which researchers and other professionals build the videographability of the activity. The paper articulates these two aspects by studying activities dealing with food, in which the participants engage in touching food as a relevant sensorial practice within their ongoing course of action

COrE (Cosmic Origins Explorer) A White Paper

COrE (Cosmic Origins Explorer) is a fourth-generation full-sky, microwave-band satellite recently proposed to ESA within Cosmic Vision 2015-2025. COrE will provide maps of the microwave sky in polarization and temperature in 15 frequency bands, ranging from 45 GHz to 795 GHz, with an angular resolution ranging from 23 arcmin (45 GHz) and 1.3 arcmin (795 GHz) and sensitivities roughly 10 to 30 times better than PLANCK (depending on the frequency channel). The COrE mission will lead to breakthrough science in a wide range of areas, ranging from primordial cosmology to galactic and extragalactic science. COrE is designed to detect the primordial gravitational waves generated during the epoch of cosmic inflation at more than $3\sigma$ for $r=(T/S)>=10^{-3}$. It will also measure the CMB gravitational lensing deflection power spectrum to the cosmic variance limit on all linear scales, allowing us to probe absolute neutrino masses better than laboratory experiments and down to plausible values suggested by the neutrino oscillation data. COrE will also search for primordial non-Gaussianity with significant improvements over Planck in its ability to constrain the shape (and amplitude) of non-Gaussianity. In the areas of galactic and extragalactic science, in its highest frequency channels COrE will provide maps of the galactic polarized dust emission allowing us to map the galactic magnetic field in areas of diffuse emission not otherwise accessible to probe the initial conditions for star formation. COrE will also map the galactic synchrotron emission thirty times better than PLANCK. This White Paper reviews the COrE science program, our simulations on foreground subtraction, and the proposed instrumental configuration.Comment: 90 pages Latex 15 figures (revised 28 April 2011, references added, minor errors corrected

Oxidative stress and immunologic responses following a dietary exposure to PAHs in Mya arenaria

<p>Abstract</p> <p>Background</p> <p>The aim of this research was to investigate oxidative stress and immune responses following a dietary polycyclic aromatic hydrocarbon (PAH) exposure in a marine bioindicator organism, the soft shell clam, <it>Mya arenaria</it>. Immune parameters in hemolymph (haemocyte number, efficiency of phagocytosis and haemocyte activity) and assessment of oxidative stress using catalase (CAT) activity and levels of malondialdehyde (MDA) performed on the digestive gland were estimated as biomarkers in clams fed in mesocosm with PAH contaminated phytoplankton. MDA levels and CAT activities were also measured <it>in situ </it>in organisms sampled in a control site (Metis Beach, Québec, Canada) as well as organisms sampled in a site receiving domestic effluents (Pointe-au-Père, Québec, Canada), to assess effects of abiotic variables related to seasonal variations and mixed contamination on the selected parameters.</p> <p>Results</p> <p>Results on immune parameters suggest that the PAHs may interfere with the maturation and/or differentiation processes of haemocytes. MDA results showed that lipid peroxidation did not occur following the exposure. The levels of CAT activity corresponded to weak antioxidant activity (no significant differences). Recovery was noted for all the immune endpoints at the end of the experiment.</p> <p>Conclusion</p> <p>Results suggest that immune parameters are early biomarkers that can efficiently detect a physiological change during a short term exposure to low concentrations of PAHs. The <it>in situ </it>survey (in the natural environment) suggested that clams from the Pointe-au-Père site did not show any oxidative stress as well as the clams contaminated in mesocosm, probably due to the low concentrations of PAHs used for this study. MDA levels increased however in organisms from Metis Beach, a response probably related to domestic effluents or parasitism.</p

Pre- and syn-eruptive degassing and crystallisation processes of the 2010 and 2006 eruptions of Merapi volcano, Indonesia

The 2010 eruption of Merapi (VEI 4) was the volcano’s largest since 1872. In contrast to the prolonged and effusive dome-forming eruptions typical of Merapi’s recent activity, the 2010 eruption began explosively, before a new dome was rapidly emplaced. This new dome was subsequently destroyed by explosions, generating pyroclastic density currents (PDCs), predominantly consisting of dark coloured, dense blocks of basaltic andesite dome lava. A shift towards open-vent conditions in the later stages of the eruption culminated in multiple explosions and the generation of PDCs with conspicuous grey scoria and white pumice clasts resulting from sub-plinian convective column collapse. This paper presents geochemical data for melt inclusions and their clinopyroxene hosts extracted from dense dome lava, grey scoria and white pumice generated during the peak of the 2010 eruption. These are compared with clinopyroxene-hosted melt inclusions from scoriaceous dome fragments from the prolonged dome-forming 2006 eruption, to elucidate any relationship between pre-eruptive degassing and crystallisation processes and eruptive style. Secondary ion mass spectrometry analysis of volatiles (H2O, CO2) and light lithophile elements (Li, B, Be) is augmented by electron microprobe analysis of major elements and volatiles (Cl, S, F) in melt inclusions and groundmass glass. Geobarometric analysis shows that the clinopyroxene phenocrysts crystallised at depths of up to 20 km, with the greatest calculated depths associated with phenocrysts from the white pumice. Based on their volatile contents, melt inclusions have re-equilibrated during shallower storage and/or ascent, at depths of ~0.6–9.7 km, where the Merapi magma system is interpreted to be highly interconnected and not formed of discrete magma reservoirs. Melt inclusions enriched in Li show uniform “buffered” Cl concentrations, indicating the presence of an exsolved brine phase. Boron-enriched inclusions also support the presence of a brine phase, which helped to stabilise B in the melt. Calculations based on S concentrations in melt inclusions and groundmass glass require a degassing melt volume of 0.36 km3 in order to produce the mass of SO2 emitted during the 2010 eruption. This volume is approximately an order of magnitude higher than the erupted magma (DRE) volume. The transition between the contrasting eruptive styles in 2010 and 2006 is linked to changes in magmatic flux and changes in degassing style, with the explosive activity in 2010 driven by an influx of deep magma, which overwhelmed the shallower magma system and ascended rapidly, accompanied by closed-system degassing

From unemployment to vocational integration : toward an integrative temporal model

Cette thèse a pour objectif de proposer un cadre global dans l’étude de l’influence des conséquences identitaires du chômage sur la réinsertion professionnelle. La Partie I propose une revue de littérature ancrée dans les théories du Soi, et pointe l’intérêt de la prise en compte de la perspective future dans l’étude du chômage et de la réinsertion. La Partie II s’intéresse aux stéréotypes des demandeurs d’emploi (Manuscrit 1) et montre l’influence négative du chômage sur les concepts de soi actuels et futurs de ces personnes (Manuscrit 2). Elle traite aussi de l’influence des processus d’identification actuelle à l’endogroupe et future à l’exogroupe de salariés (Manuscrit 3) sur le pessimisme. Un dernier manuscrit œuvre à déterminer différents profils d’identification et leur impact sur le stress (Shortnote 1). Les études présentées dans la partie III sont centrées sur les antécédents de la recherche d’emploi. Un premier manuscrit présente la validation d’une nouvelle mesure, celle de motivation à (re)travailler (Manuscrit 4). Deux autres manuscrits s’intéressent au construit de Considération pour les Conséquences Futures, le premier en proposant une validation française de l’outil (Manuscrit 5) et un second ayant pour but de montrer l’intérêt d’étudier ce construit à un niveau contextuel (Manuscrit 6). Ces deux nouvelles mesures permettent de proposer un modèle temporel de la recherche d’emploi présenté dans un dernier document (Shortnote 2). Enfin, la Partie IV présente les premiers éléments statuant de l’influence de l’identification sur le modèle de la recherche d’emploi. Une discussion sur les apports et les ouvertures de ce travail doctoral conclut ce document.This thesis aims to provide a comprehensive framework in the study of identity consequences of unemployment on vocational rehabilitation. Part I offers a review of the literature rooted in the theories of the Self, and points to the interest of taking into account future time perspective in the study of unemployment and reintegration. Part II takes an interest in the jobseekers’ stereotypes (Manuscript 1) and shows the negative impact of unemployment on current and future self-concepts of jobseekers (Manuscript 2). It also deals with the influence of identification processes –actual to the in-group and future to the out-group of workers- on the pessimism of job-seekers (Manuscript 3). A last manuscript aims at identifying specific identification profiles and study their impact on perceived stress (Shortnote 1). Studies presented in Part III focus on job search antecedents. A first manuscript presents the creation and validation of a new measure of the motivation to work again (manuscript 4). Two other manuscripts deal with another important construct – the Consideration for Future Consequences-, the first with the objective of validating a version of the tool in French (Manuscript 5) and the second with the aim of showing the interest to consider this construct at a contextual level of generality (Manuscript 6). Those two new measures helped to test for a temporal model of job search that is presented in a last manuscript (Shortnote 2). The fourth part focuses her to present the first elements which argue in favor of identification influence on the temporal job search model. A discussion on the contributions and openings of this doctoral work concludes this document
