Cette thèse de doctorat, écrite en anglais, propose la première édition critique de « Because of the Dollars », une nouvelle de l'écrivain anglais Joseph Conrad publiée dans le volume Within the Tides, en février 1915. Outre le texte critique de la nouvelle - le seul à ce jour reconstruit d'après une minutieuse étude des relations entre toutes les versions existantes - la présente édition offre aussi un vaste apparat éditorial. Le texte de la présente édition est éclectique. Sa ponctuation est essentiellement basée sur un texte proche du manuscrit de l'auteur, et donc non corrompu par le processus de transmission. Mais ses mots sont tirés des dernières versions révisées par l'auteur, étant donné qu'au cours de la transmission, les mots, contrairement aux marques de ponctuation, n'ont pas été contaminés. Le résultat de cette méthode est un texte reflétant, tant pour les mots que pour la ponctuation, les choix de l'auteur. L'apparat éditorial sert à placer la nouvelle dans la vie de Conrad, tracer l'évolution du texte, et offrir au lecteur des informations historiques et culturelles qui permettront une meilleure lecture de l'oeuvre. Cet apparat est composé de quatre parties : une introduction, une étude sur les textes de la nouvelle, une collation historique de toutes les variantes, et des notes explicatives. L'introduction place l'oeuvre dans le contexte de la vie de l'écrivain, en donne la réception critique de 1915 à nos jours, et en éclaire le contexte historique (un changement de monnaie à Singapour en 1903-4). L'étude sur les textes trace le développement et la transmission du texte, depuis son inscription sur pages manuscrites jusqu'à sa publication dans les oeuvres complètes de Conrad. La collation historique inventorie toutes les variantes textuelles entre les différentes versions existantes. Enfin, les notes explicatives glosent les allusions littéraires, historiques, et culturelles du texte. « Because of the Dollars » et Within the Tides n'ayant attiré que très peu d'attention critique, les informations contenues dans cet apparat éditorial sont complètement inédites, et jettent une lumière originale sur une période peu étudiée de la vie de Conrad.

We describe a case of experimentally induced pre-syncope in a healthy young man when exposed to increased inspired CO2 in a background of hypoxia. Acute severe hypoxia (FIO2=0.10) was tolerated, but adding CO2 to the inspirate caused pre-syncope symptoms accompanied by hypotension and large reductions in both mean and diastolic middle cerebral artery velocity, while systolic flow velocity was maintained. The mismatch of cerebral perfusion pressure and vascular tone caused unique retrograde cerebral blood flow at the end of systole and a reduction in cerebral tissue oxygenation. We speculate that this occurrence of pre-syncope was due to hypoxia-induced inhibition of brain regions responsible for compensatory sympathetic activity to relative hypercapnia.

The human auditory system is comprised of specialized but interacting anatomic and functional pathways encoding object, spatial, and temporal information. We review how learning-induced plasticity manifests along these pathways and to what extent there are common mechanisms subserving such plasticity. A first series of experiments establishes a temporal hierarchy along which sounds of objects are discriminated along basic to fine-grained categorical boundaries and learned representations. A widespread network of temporal and (pre)frontal brain regions contributes to object discrimination via recursive processing. Learning-induced plasticity typically manifested as repetition suppression within a common set of brain regions. A second series considered how the temporal sequence of sound sources is represented. We show that lateralized responsiveness during the initial encoding phase of pairs of auditory spatial stimuli is critical for their accurate ordered perception. Finally, we consider how spatial representations are formed and modified through training-induced learning. A population-based model of spatial processing is supported wherein temporal and parietal structures interact in the encoding of relative and absolute spatial information over the initial ∼300ms post-stimulus onset. Collectively, these data provide insights into the functional organization of human audition and open directions for new developments in targeted diagnostic and neurorehabilitation strategies.

El sentit comú ens diu que si una persona que està treballant, és a dir, produint, deixa de fer-ho en ser pre-jubilada, posem als 52 anys, la societat a la que pertany disminueix el seu potencial productiu. No obstant això les pre-jubilacions es defensen normalment com una necessitat per a que l’empresa sigui més competitiva i així el país sigui més competitiu. L’absurd a que es refereix el títol pot resumir-se així: ‘reduir el potencial productiu del país per a fer el país més competitiu’. Com d’altres absurds similars, te, clar, la seva ‘explicació’ social-política. I de fet els economistes tendim a mirar amb certa condescendència als qui verbalitzen un absurd d’aquests tipus, perquè deduïm que qui ho fa no és capaç d’adonar-se’n que aquestes qüestions econòmiques no són tan senzilles. O, en el fons si que ho són?

Most natural killer T (NKT) cells express a highly skewed alphabeta TCR repertoire, consisting of an invariant V alpha14-J alpha281 chain paired preferentially with a polyclonal Vbeta8.2 chain. This repertoire is positively selected by the monomorphic CD1d molecule expressed on cells of hematopoietic origin. The origin of NKT cells and their lineage relationship to conventional T cells is controversial. We show here that the development of NKT cells is absolutely dependent on expression of the pre-TCRalpha chain, in marked contrast to conventional T cells which arise in significant numbers even in the absence of a functional pre-TCR. Distinct developmental requirements for pre-TCR expression in the NKT and T cell lineages may reflect differences in the ability of the TCRalphabeta to substitute functionally for the pre-TCR in immature precursor cells.

INTRODUCTION: In 2009 hypovitaminosis D was highly prevalent in a population of Swiss rheumatology patients (86%). We aimed to evaluate the evolution of vitamin D status in the same population two years later, after the results of the first study were disseminated to local physicians and patients, in order to determine the evolution of the problem and the impact of physician information. METHOD: Patients in our rheumatology clinic were screened for 25-OH vitamin D. Results were categorised as: deficient (<10 ng/ml or <25 nmol/l), insufficient (10 to 30 ng/ml or 25 to 75 nmol/l) or normal (>30 ng/ml or >75 nmol/l). We also used another cut-off of 20 ng/ml (50 nmol/l). We evaluated the evolution of 25-OH vitamin D dosages and vitamin D3 prescriptions between 2008 and 2011 in our institution and the number of publications on vitamin D in three important medical journals of the French speaking part of Switzerland. RESULTS: Compared with 2009, significantly more patients had normal results in 2011. Fifty-two percent of patients had levels >20 ng/ml in 2009 and 66% in 2011, difference statistically significant (p = 0.001). During the years separating the two study periods the number of 25-OH vitamin D dosages and the prescription of high doses of vitamin D3 increased in our hospital. In addition the number of publications on vitamin D increased between 2008 and 2011. CONCLUSION: We concluded that lower prevalence in hypovitaminosis D is certainly related to better adherence to daily supplements, and to better information and awareness of the physicians about hypovitaminosis D.

ABSTRACT: Apprenticeship is a period of increased risk of developing work-related respiratory allergic diseases. There is a need for documents to provide appropriate professional advice to young adults aiming to reduce unsuitable job choices and prevent impairment from their careers. The present document is the result of a consensus reached by a panel of experts from European and non-European countries addressed to allergologists, pneumologists, occupational physicians, primary care physicians, and other specialists interested in this field, which aims to reduce work-related respiratory allergies (rhinoconjunctivitis and asthma) among allergic or nonallergic apprentices and other young adults entering the workforce. The main objective of the document is to issue consensus suggestions for good clinical practice based on existing scientific evidence and the expertise of a panel of physicians.

When dealing with sustainability we are concerned with the biophysical as well as the monetary aspects of economic and ecological interactions. This multidimensional approach requires that special attention is given to dimensional issues in relation to curve fitting practice in economics. Unfortunately, many empirical and theoretical studies in economics, as well as in ecological economics, apply dimensional numbers in exponential or logarithmic functions. We show that it is an analytical error to put a dimensional unit x into exponential functions ( a x ) and logarithmic functions ( x a log ). Secondly, we investigate the conditions of data sets under which a particular logarithmic specification is superior to the usual regression specification. This analysis shows that logarithmic specification superiority in terms of least square norm is heavily dependent on the available data set. The last section deals with economists’ “curve fitting fetishism”. We propose that a distinction be made between curve fitting over past observations and the development of a theoretical or empirical law capable of maintaining its fitting power for any future observations. Finally we conclude this paper with several epistemological issues in relation to dimensions and curve fitting practice in economics

Schistosomiasis control seems to be different in countries were low parasitic burden and asymptomatic clinical patients are the features of majority of cases. Immunological methods must substitute the traditional coprologic techniques used for some decades in the Control Program. Circumoval Precipitin Test (COPT), intradermal test and ELISA with soluble egg antigen (SEA) are evaluated for using as tools for seroepidemiologic studies. COPT and ELISA were performed after treatment to known their utility when impact of chemotherapy must be assessed. One hundred sixty five persons were followed up 3, 6, 9 and 12 months after treatment. The mean sensitivity of CPT studied by age groups was 95.6% which is very important considering that 88.4% of the studied population excreted less than 100 egg/gr of feces, while sensitivity of intradermal test was 58.2%. Children showed the highest ractivity to COPT. When treatment is effective, COPT reactivity progressively disminish until become negative one year later. In the non cure group, the COPT reactivity disminished but never below 20%. ELISA-SEA did not modify one year after treatment. Effort should be made to isolate fractions of eggs Schistosoma mansoni whose antibodies disappear after treatment.

La correspondance paulinienne réserve, dans ses passages oubliés, quelques surprises propres à nous faire réviser une image figée de Paul. Ainsi 1 Th 2/1-12, où l'apôtre présente son investissement dans la mission sous la double figure de la mère et du père. Daniel MARGUERAT montre que le vocabulaire affectif afflue dans ce texte où Paul appelle les chrétiens de Thessalonique à identifier dans leur histoire personnelle les traces de la puissance de l'évangile. Conscience collective de l'apostolat et lecture théologique des relations interpersonnelles constituent deux accents forts de ce plus ancien écrit de l'apôtre de Tarse.

The epidemiological methods have become useful tools for the assessment of the effectiveness and safety of health care technologies. The experimental methods, namely the randomized controlled trials (RCT), give the best evidence of the effect of a technology. However, the ethical issues and the very nature of the intervention under study sometimes make it difficult to carry out an RCT. Therefore, quasi-experimental and non-experimental study designs are also applied. The critical issues concerning these designs are discussed. The results of evaluative studies are of importance for decision-makers in health policy. The measurements of the impact of a medical technology should go beyond a statement of its effectiveness, because the essential outcome of an intervention or programme is the health status and quality of life of the individuals and populations concerned.
