Vertical seismic profiling of glaciers: appraising multi-phase mixing models
Authors: Gusmeroli Alessio , Murray Tavi , Clark Roger A. , Kulessa Bernd , Jansson Peter 
Published: May 2013

AbstractWe have investigated the speed of compressional waves in a polythermal glacier by, first, predicting them from a simple three-phase (ice, air, water) model derived from a published ground-penetrating radar study, and then comparing them with field data from four orthogonally orientated walkaway vertical seismic profiles (VSPs) acquired in an 80 m deep borehole drilled in the ablation area of Storglaciären, northern Sweden. The model predicts that the P-wave speed increases gradually with depth from 3700ms–1 at the surface to 3760ms–1 at 80m depth, and this change is almost wholly caused by a reduction in air content from 3% at the surface to <0.5% at depth. Changes in P-wave speed due to water content variations are small (<10 ms–1); the model’s seismic cold–temperate transition surface (CTS) is characterized by a 0.3% decrease downwards in P-wave speed (about ten times smaller than the radar CTS). This lack of sensitivity, and the small contrast at the CTS, makes seismically derived water content estimation very challenging. Nevertheless, for down-going direct-wave first arrivals for zero- and near-offset VSP shots, we find that the model-predicted travel times and field observations agree to within 0.2 ms, i.e. less than the observational uncertainties.
Les Chalandonnettes
Authors: Steinmetz Hélène 
Published: May 2013

Cet article traite de la contribution de l’action publique à la genèse et à la dévalorisation des formes de la propriété populaire, en interrogeant la construction politique des marchés du logement. Il analyse précisément la manière dont le ministère de l’Équipement suscite, au début des années 1970, une offre de maisons individuelles à bas prix, à travers la construction de près de 70 000 pavillons connus sous le nom de « chalandonnettes ». En se fondant sur les archives du ministère, ce texte analyse le rôle des hauts fonctionnaires de l’Équipement dans la genèse de cette politique. À la fin des années 1960, la nécessité d’une intervention directe et centralisée de l’État dans la production de maisons « bas de gamme », pour encadrer le développement spontané de l’habitat pavillonnaire, s’impose parmi eux comme une évidence. Toutefois, les transformations des rapports de force dans le champ des politiques du logement, au cours des années 1970, contribuent à la perte de légitimité de cette forme d’action publique, au profit d’une intervention étatique plus indirecte sur le marché de la maison à bas prix, qui contribue à redessiner l’espace des possibles de la propriété populaire.
Une maison pour le peuple portugais
Authors: Borges Pereira Virgílio , Queirós João 
Published: May 2013

À partir d’une caractérisation générale de la « question du logement » dans la première moitié du XX e siècle au Portugal, cet article propose une analyse du processus de mise en œuvre de la première grande politique de logement de l’État portugais : le programme des maisons économiques ( programa das casas económicas ), la réponse de l’ Estado Novo à la crise du logement qui sévit à l’époque dans le pays, organisée en 1933 autour de la promotion de la propriété de la maison. En s’appuyant sur l’étude de la législation, sur des données issues d’archives et tirant parti des mémoires de résidents âgés, le texte reconstitue les processus de sélection sociale, de ségrégation spatiale et de contrôle moral qui organisaient le quotidien du plus grand quartier de maisons économiques de la ville de Porto – le quartier d’Amial , construit en 1938 et étendu en 1958.
Devenir propriétaire en cité HLM
Authors: Gilbert Pierre 
Published: May 2013

La différenciation croissante à l’intérieur des classes populaires se manifeste notamment par un clivage entre fractions précaires des cités HLM et fractions stables propriétaires des zones pavillonnaires. En promouvant l’accession à la propriété au cœur des cités, la politique de rénovation urbaine est susceptible de modifier les logiques à l’origine de ce clivage résidentiel. À partir d’une monographie de quartier, cet article souligne que, au lieu des classes moyennes attendues, les accédants à la propriété appartiennent aux fractions stables des classes populaires. Devenir propriétaire en cité HLM leur permet de connaître une petite mobilité résidentielle tout en préservant les liens familiaux et de proximité essentiels à leur équilibre domestique. Leur trajectoire et les efforts imposés par ce nouvel habitat les conduisent à investir intensément leur monde privé et à mettre à distance le quartier et ses habitants les moins « respectables ». Si la rénovation urbaine modifie le peuplement des cités en freinant les logiques centrifuges qui suscitaient jusque-là le départ des catégories stables, la cohabitation de celles-ci avec les plus précaires ne se traduit donc pas par leur rapprochement social.
La gauche et le périurbain
Authors: Lambert Anne 
Published: May 2013

Comment les élus des petites communes périurbaines se saisissent-ils des politiques nationales de logement – entre soutien à la propriété et promotion de la mixité sociale – pour tenter d’agir sur le bâti et le peuplement de leur territoire ? C’est la question que pose cet article à partir de l’étude d’une commune pavillonnaire en forte croissance et passée à gauche en 1983, un contexte dans lequel la question de la mixité sociale n’est que très rarement posée. L’analyse des logiques socio-politiques et institutionnelles qui sous-tendent, localement, la production des lotissements révèle, dès lors, leur ambiguïté : les grands lotissements « à l’américaine » visent à attirer les familles de classes moyennes lyonnaises, tandis que l’imposition de quotas de logements sociaux dans les nouveaux programmes doit permettre de loger les ménages modestes de la commune, majoritairement ouvriers et employés. Toutefois, la politique des élus se trouve largement infléchie par les promoteurs immobiliers, en particulier en période de crise économique. L’analyse statistique du peuplement des lotissements montre en effet l’écart qui sépare le projet politique de sa réalisation, avec l’apparition de processus de micro-ségrégation sociale et raciale à l’échelle des lotissements.
Physician Specialty and Variations in Adoption of Electronic Health Records
Authors: Banerjee S. , Kaushal R. , Kern L.M. , Grinspan Z. M. 
Published: May 2013

SummaryObjective: Efforts to promote adoption of electronic health records (EHRs) have focused on primary care physicians, who are now expected to exchange data electronically with other providers, including specialists. However, the variation of EHR adoption among specialists is underexplored.Methods: We conducted a retrospective cross-sectional study to determine the association between physician specialty and the prevalence of EHR adoption, and a retrospective serial cross-sectional study to determine the association of physician specialty and the rate of EHR adoption over time. We used the 2005–2009 National Ambulatory Medical Care Survey. We considered fourteen specialties, and four definitions of EHR adoption (any EHR, basic EHR, full EHR, and a novel definition of EHR sophistication). We used multivariable logistic regression, and adjusted for several covariates (geography, practice characteristics, revenue characteristics, physician degree).Results: Physician specialty was significantly associated with EHR adoption, regardless of the EHR definition, after adjusting for covariates. Psychiatrists, dermatologists, pediatricians, ophthalmologists, and general surgeons were significantly less likely to adopt EHRs, compared to the reference group of family medicine / general practitioners. After adjustment for covariates, these specialties were 44 – 94% less likely to adopt EHRs than the reference group. EHR adoption increased in all specialties, by approximately 40% per year. The rate of EHR adoption over time did not significantly vary by specialty.Conclusions: Although EHR adoption is increasing in all specialties, adoption varies widely by specialty. In order to insure each individual’s network of providers can electronically share data, widespread adoption of EHRs is needed across all specialties.Citation: Grinspan ZM, Banerjee S, Kaushal R, Kern LM.

Published: May 2013

Background: This study was conducted to assess whether choices of physical activity, smoking status, and parental education and income were correlated with the health status of young adult males which are important for preventive health policy. Methods: 491 18-29-year old males from lower socioeconomical districts in Turkey participated in this study. Information about demographic characteristics, parental education, household income, smoking status, and physical activity was obtained by means of a standardized questionnaire. BMI and metabolic parameters (serum lipid profile) were assessed.Results: Mean total cholesterol, LDL, HDL and triglyceride levels were in the normal range. The physically active group displayed a better lipid profile. No relationship was found between parental education and serum lipids. Smoking was slightly correlated with household income (r=103, p=0.022).Conclusion: Young adult males who participate in relatively high levels of physical activity are at lower CHD risk than less active ones. The present study also showed that lower socioecnomic status does not always correlate with higher levels of cardiovascular risk factors. In conclusion, data supports that while family history cannot be changed, HDL levels can be modulated by lifestyle factors as in other populations and that with the determined benefits of increasing physical activity and thus, HDL levels, policy reform in schools to promote physical activity are warranted.

Nos últimos anos, muitos pesquisadores dedicaram atenção à questão da importância dos indicadores sociais na redução de doenças. O objetivo deste artigo é analisar a associação estatística entre os casos notificados de AIDS e algumas variáveis socioeconômicas. Foi analisada uma amostra de 1.994 municípios brasileiros com casos de AIDS informados em 1991 e 2000. As variáveis analisadas são: taxa de incidência de AIDS per capita; taxa de analfabetismo; Índice de Gini; renda per capita; acesso a eletricidade e televisão; esperança de vida ao nascer. A abordagem econométrica usada neste estudo foi modelo de dados em painel. Os resultados desta análise mostram que as variáveis socioeconômicas são importantes para entender a incidência dos casos de AIDS no Brasil, e são importantes para o desenho de políticas públicas para o combate do aumento da incidência de HIV/AIDS; além de mostrarem um padrão distinto ao encontrado na literatura para países africanos. In recent years, many researchers have devoted attention to the issue of the importance of social indicators in disease reduction. The objective of this paper is to analyze the statistical association between the reported AIDS cases and some socioeconomic variables.

Translation as Politics: The Translation of Sadako Kurihara’s War Poems
Authors: Hayakawa Atsuko 
Published: May 2013

The dynamic power shift of the world picture from a dominant hegemonic power structure to a global consciousness of hybridity accelerated by postcolonialism in the late 20th century has opened up a way to re-read history from a new perspective. The major point in the process is the recognition of both the cultural and political others which had long been made invisible and silent by the politics of power. It is in this light that translation must be addressed by scholarly discourse.
This paper focuses on war poems by Sadako Kurihara both in the time of and after the censorship that occurred during the occupation. Through the lens of translation and its modalities, I would propose here, history can be re-addressed. How the narrative of translation creates an arena where an individual voice is made to be heard in the language of others is closely related with the translator’s stance in the political context. The task of the translator today is much more important than ever, not only culturally but also ethically.
La traduction d’Eugène Onéguine de Pouchkine – étude comparative multilingue
Authors: Kim Simon 
Published: May 2013

Eugène Onéguine, écrit par Pouchkine à la fin du XIXesiècle, est l’une des oeuvres majeures de la littérature russe. Souvent dans l’ombre de l’opéra éponyme de Tchaïkovsky, son statut est souvent méconnu hors des milieux russophiles; néanmoins, nombreux sont les traducteurs qui s’attaquent à ce texte, que Pouchkine lui-même définit comme un « roman en vers ». De par sa nature hybride (ni roman, ni poème,à la foispoèmeetroman) et son caractère multilingue ou polyglotte (Bakhtine), possédant une forme originale (si bien qu’on parle même de « strophe onéguienne »), ce texte constitue un véritable défi que les traducteurs, et même les traducteurs non russophones (Hofstadter, Giudici), sont souvent avides de relever.Si les langues occidentales, riches elles aussi en systèmes métriques et en versification rimée, ont la tentation de transposer le vers russe dans une forme versifiée occidentale, pour les traducteurs occidentaux la question demeure de définir ce qu’estEugène Onéguine, sachant qu’il échappe à toutes les définitions traditionnelles.Pour les langues orientales, comme le coréen ou le japonais, qui n’ont pas les mêmes traditions linguistiques, littéraires et poétiques, les enjeux dans la traduction sont à première vue plus complexes puisqu’il s’agit d’inventer ou de renoncer à rendre une forme qui est tout aussi importante que le sujet de cette oeuvre. La distinction entre les deux est d’ailleurs rendue caduque par ce texte qui remet précisément en cause cette distinction. Or, l’observation des différentes approches traductives en langues occidentales et orientales permet de mettre en lumière cette caractéristique du texte de Pouchkine et de sa traduction. Car si la familiarité des langues occidentales avec le mètre et le vers semble apparemment poser au traducteur la question du genre (roman/poème, prose poétique/poésie « prosaïque »), l’altérité ou l’étrangeté des langues orientales révèle que la tâche du traducteur est, et a toujours été – même pour les traducteurs occidentaux – non pas tant de restituer un (semblant de) vers, mais de créer une forme, un texte qui fasse « ce que fait le texte » (Meschonnic).
Polycythemia vera and essential thrombocythemia: 2013 update on diagnosis, risk‐stratification, and management
Authors: Tefferi Ayalew 
Published: May 2013

Disease OverviewPolycythemia Vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms (MPN) primarily characterized by erythrocytosis and thrombocytosis, respectively. Other disease features include leukocytosis, splenomegaly, thrombohemorrhagic complications, vasomotor disturbances, pruritus and a small risk of disease progression into acute myeloid leukemia or myelofibrosis.DiagnosisAlmost all patients with PV harbor aJAK2mutation. When PV is suspected, the presence of aJAK2mutation highly suggests the diagnosis and its absence, combined with normal or increased serum erythropoietin level, excludes the diagnosis. Differential diagnosis of ET should include reactive thrombocytosis, chronic myeloid leukemia, prefibrotic myelofibrosis and RARS‐T (refractory anemia with ring sideroblasts associated with marked thrombocytosis). AJAK2mutation is found in 50–70% of patients with ET, myelofibrosis or RARS‐T and is capable of distinguishing reactive from clonal thrombocytosis.Risk StratificationCurrent risk stratification in PV and ET is designed to estimate the likelihood of thrombotic complications: high‐risk is defined by the presence of age >60 years or presence of thrombosis history; low‐risk is defined by the absence of both of these two risk factors. Recent data considersJAK2V617F and cardiovascular (CV) risk factors as additional risk factors for thrombosis. Presence of extreme thrombocytosis (platelet count >1,000 × 109/L) might be associated with acquired von Willebrand syndrome (AvWS) and, therefore, risk of bleeding. Risk factors for shortened survival in both PV and ET include advanced age, leukocytosis, and history of thrombosis.Risk‐Adapted TherapySurvival is near‐normal in ET and reasonably long in PV. The 10‐year risk of leukemic/fibrotic transformation is <1%/1% in ET and <3%/10% in PV. In contrast, the risk of thrombosis exceeds 20%. The main goal of therapy is therefore to prevent thrombohemorrhagic complications. In low risk patients, this is effectively and safely accomplished by the use of low‐dose aspirin in both PV and ET and phlebotomy (hematocrit target of <45%) in PV. In high risk patients, treatment with hydroxyurea is additionally recommended, although not mandated in older patients withoutJAK2V617F or CV risk factors. Treatment with busulfan or interferon‐α is usually effective in hydroxyurea failures. Screening for clinically significant AvWS is recommended before administrating aspirin in the presence of extreme thrombocytosis. Am. J. Hematol. 88:508–516, 2013. © 2013 Wiley Periodicals, Inc.
Chimerism in monochorionic dizygotic twins: Case study and review
Authors: Chen Kristen , Chmait Ramen H. , Vanderbilt Douglas , Wu Samuel , Randolph Linda 
Published: May 2013

AbstractChimerism occurs when an organism contains cells derived from more than one distinct zygote. We focus on monochorionic dizygotic twin blood chimerism, and particularly twin–twin transfusion syndrome in such pregnancies. For years, researchers have understood chimerism to be a common phenomenon in cattle. Although, this review will not delve deeply into animal chimerism, an understanding of chimerism in the animal world can provide clues regarding health implications for human chimeras. This report serves two purposes: an update and assessment of the twins we reported previously in 2010 [Assaf et al., 2010] and a review on dizygotic monochorionic chimeric twins. First, our updated assessment of the twins shows no identifiable regression of Müllerian sex derivatives in the female, and normal neurodevelopment was documented in both. Our research has suggested several key points; one that blood chimerism persists from fetal life to at least age two years. Second, chimerism in humans is not as rare as previously thought, although it has been studied only recently. Third, assisted reproductive technologies appear to increase the risk of monochorionic dizygotic twin pregnancies. © 2013 Wiley Periodicals, Inc.
Two is better than one: A case of homozygous myotonic dystrophy type 1
Authors: Carroll Jillian M. , Quaid Kimberly A. , Stone Kristyne , Jones Renee , Schubert Frank , Griffith Christopher B. 
Published: May 2013

AbstractMyotonic dystrophy type 1 is an autosomal dominant condition caused by a trinucleotide CTG repeat expansion in the 3′ untranslated region of the dystrophia myotonica protein kinase gene. The phenotypic features of myopathic facies, generalized weakness, and myotonia are thought to be dependent on repeat number, with larger expansions generally leading to earlier and/or more severe disease. The vast majority of individuals are heterozygous for an expanded allele and an allele in the normal range. In this clinical report, we describe two brothers with congenital myotonic dystrophy type 1. The younger of the two siblings is one of only 13 homozygous patients ever reported in the literature. He carries two expanded alleles: one with 1,170 repeats and the other with >100 repeats. We present his clinical picture in relation to his more severely affected heterozygous brother as well as other published homozygous cases. Finally, we discuss the inconsistency between repeat size and symptomatic expression as it applies to the current proposed mechanisms of myotonic dystrophy type 1 pathogenicity. © 2013 Wiley Periodicals, Inc.
Layer‐by‐layer assembled hydrogel nanocomposite film with a high loading capacity
Authors: Gu Renbao , Yuan Xinglin , Wu Ronglan , Li Huili , Xu Shimei , Wang Jide 
Published: May 2013

ABSTRACTThe layer‐by‐layer assembly technique is a method that widely used in the preparation of nanostructured multilayer ultrathin films. We fabricated a hydrogel nanocomposite film by alternating the deposition of a core–shell poly[(dimethylimino)(2‐hydroxy‐1,3‐propanedily) chloride] (PDMIHPC)–laponite solution and poly(acrylic acid). The growth of the deposition procedure was proven by ultraviolet–visible spectroscopy and spectroscopic ellipsometry. The surface morphology of the films was observed by scanning electron microscopy. The films could reversibly load and release methylene blue (MB) dye, which was used as an indicator. It took about 4.5 h to reach loading equilibrium at pH 9.0. The loading capacity of the film for MB was as large as 4.48 μg/cm2 per bilayer because of the introduction of the core–shell PDMIHPC–laponite as a film component. Nearly 90% of MB was released at pH 3.0 or in a 300 mM NaCl solution within 2.5 h. The loading and release processes were greatly influenced by the ionic strength and pH value of the MB solution. The hydrogel nanocomposite film showed good pH‐triggered loading‐release reversibility and suggested potential applications in controlled drug‐delivery systems and smart materials. © 2013 Wiley Periodicals, Inc.
