Les printemps arabes croqués par le dessinateur de presse Godfrey Mwampembwa (dit Gado)
Authors: Panov Alexander A. 
Published: June 2013

Dans cet article, Alexander A. Panov livre une analyse et sa propre perception du travail de Gado, l’un des plus célèbres caricaturistes politiques en Afrique. À travers l’étude d’une série de ses dessins de presse sur les « printemps arabes », publiés entre octobre 2010 et décembre 2011, il décrypte la perception de ce processus sociopolitique nord-africain en Afrique de l’Est. En toile de fond émerge l’idée que, pour de nombreux militants, journalistes, commentateurs et lecteurs, au moment de la publication de ces dessins, les soulèvements populaires en Afrique du Nord pouvaient aussi être une réalité dans les pays d’Afrique subsaharienne.
Le « boom » des saisons dans l'espace sahélo-saharien
Authors: Niang Amy 
Published: June 2013

Le Sahel connaît des crises structurelles sur lesquelles les acteurs formels n’ont guère de prise. La diffusion des printemps arabes vers le sud du continent a accéléré et intensifié son intégration dans les processus mondiaux, au point que la stabilité de la région tout entière s’en trouve menacée. L’incapacité des États sahéliens à innover sur le plan de la gouvernance et à satisfaire les attentes de leurs populations, conjuguée à la ruée sur les ressources naturelles, la radicalisation religieuse et l’« importation » de tensions extérieures, notamment, sont à l’origine de l’avènement d’une nouvelle ère mondiale où des griefs locaux trouvent une tribune internationale.
Travail et représentation des intérêts collectifs à l'épreuve de la globalisation
Authors: Dequecker Corinne , Tixier Pierre-Éric 
Published: June 2013

La transformation des entreprises sous l’effet de la globalisation se traduit par un changement du rapport des salariés au travail dont les effets ont conduit au développement de courants d’analyse et de prévention autour de la souffrance au travail et des risques psychosociaux. L’article se centre sur l’analyse des transformations des mécanismes de régulation intermédiaire par le management et le dialogue social et fait l’hypothèse que leur effondrement a déstabilisé le processus de construction des intérêts collectifs des salariés. Dans le même temps la négociation collective s’est focalisée sur l’emploi délaissant le traitement des problèmes du travail. Comment dans ce contexte refonder la négociation sur le travail ?
La négociation de la prévention des risques psychosociaux : une occasion de renouveler le dialogue social
Authors: Douillet Philippe 
Published: June 2013

Le sujet des « risques psychosociaux » (RPS) est devenu un objet de négociation dans les entreprises. Mais les spécificités du sujet font que les paramètres habituels de la négociation sont bouleversés. Cet article analyse les possibilités, à partir de ce contexte, d’une inflexion durable des pratiques de négociation sur les conditions de travail et, au-delà, des relations sociales pour prendre en compte le travail et en débattre.
Politique et aggiornamento de l'Église : cinquante ans après Vatican II
Authors: Heyer René 
Published: June 2013

Le concile Vatican II a permis non seulement une mise à jour mais plus encore une mise au jour de l’attitude de l’Église face à la politique. La démocratie enracinée dans les droits de l’homme est considérée de manière positive. Il n’existe pas de « théologie politique de l’Église catholique. Le bien commun est une véritable fin. Mais Vatican II contient aussi quelques appels à la prudence sur ces questions. La « religion civile » d’un Rousseau est redoutée. C’est la liberté religieuse qui fait foi. La démocratie est « appréciée » (Jean-Paul II) sans être exaltée. Son anti-modèle est le totalitarisme. Le positionnement de l’Église face au politique demanderait sans doute à être actualisé quant à la question de la résistance publique face à des lois jugées scandaleuses.

Published: June 2013

ABSTRACT
Synovial sarcomas of head and neck are very rare and account for only 3% of all sarcomas. Approximately 5% of synovial sarcomas arise in the head and neck region and hypopharynx and larynx are the most and least often affected anatomic sites respectively. We describe a rare case of primary hypopharyngeal synovial sarcoma in a young adult.

Published: June 2013

ABSTRACTIngested foreign body is one of the most frequently encountered emergencies in otolaryngology practice. Many of these foreign bodies get lodged in the upper digestive tract and can be removed endoscopically. Few of these foreign bodies can perforate the upper digestive tract and an even smaller number of these can migrate extraluminally. Although, a migrating foreign body can remain quiescent, they can cause life-threatening suppurative or vascular complications; hence, location and removal is essential. Here we report two cases of extraluminal migration of foreign body which was removed by neck exploration.How to cite this articleDivya GM, Hameed AS, Ramachandran K, Vinayak KV.

Published: June 2013

ABSTRACTObjectiveTo emphasize that epiglottic cyst should be considered in the differential diagnosis of all adults presenting with stridor.Case reportA 55-year-old male patient presented with stridor of 2 days duration. He also had complaints of gradually progressive difficulty in swallowing for solids and had muffled voice for the past 3 months. Oropharyngeal examination revealed a large cystic mass behind the base of tongue. An indirect laryngoscopy and 70° telescopic laryngoscopy showed a large cystic mass filling both vallecular regions obscuring rest of the larynx. He underwent tracheostomy for airway distress followed by excision of the cyst.ConclusionThis case highlights the possibility of a rare presentation of epiglottic cyst in an adult presenting with stridor requiring an early definitive management.How to cite this articleChandrakala S, Bhardwaj NS, Mohammadi K, Menon L.

ABSTRACTAimTo compare risk factors for extratubal gestations with tubal gestations.Materials and methodsCase control design with retrospective examination of an electronic database to identify ectopic gestations. Ectopic gestations were confirmed through ultrasound examination or serum beta hCG levels. We defined an ectopic gestation as implantation of pregnancy outside uterine cavity; tubal ectopic including implantation in the tube, isthmic, ampullary, or fimbrial and extratubal ectopic including implantation in the ovaries, cervix, abdomen, interstitia or cesarean scar.ResultsNinety-one (1.1%, 95% CI: 0.9-1.3, 1 in 90 pregnancies) of 8,203 pregnancies during the study period were ectopic gestations including 69 (0.8%, 95% CI: 0.7-1.1, 1 in 120 pregnancies) tubal gestations and 22 (0.3%, 95% CI: 0.2-0.4, 1 in 372 pregnancies) gestations in extratubal locations. Extratubal ectopic gestations were more common in women with advanced maternal age (odds ratio: 7.4, 95% CI: 1.3, 43.9, p = 0.03) compared to women with tubal ectopic gestations.ConclusionRisk factors for extratubal gestation did not differ from risk factors for tubal gestations except for advanced maternal age. Pregnant women with advanced maternal age have to be additionally counseled on the increased risk for extratubal gestations.How to cite this articlePochiraju M, Surampudi K, Marakani LR, Dasari S, Gundabattula SR.

Gender bias in the measurement of peer victimization: An application of item response theory
Authors: Bevans Katherine B. , Bradshaw Catherine P. , Waasdorp Tracy E. 
Published: June 2013

AbstractThere continues to be great debate regarding the conceptualization and measurement of peer victimization, particularly with respect to gender differences in children's victimization experiences. We employed traditional and modern psychometric methods (e.g., item response theory) to evaluate a 10‐item youth‐report measure of peer victimization (e.g., threatening, spreading rumors/lies, and cyberbullying) among 17,198 students in Grades 6–12. A two‐factor model that differentiated between direct and indirect victimization subtypes best characterized students' experiences and substantially reduced the potential for gender‐based measurement bias. Implications for the gender‐sensitive assessment of peer victimization are discussed. Aggr. Behav. 39:370–380, 2013. © 2013 Wiley Periodicals, Inc.
Self‐Organization of Inkjet‐Printed Organic Semiconductor Films Prepared in Inkjet‐Etched Microwells

Published: June 2013

AbstractThe high‐precision deposition of highly crystalline organic semiconductors by inkjet printing is important for the production of printed organic transistors. Herein, a facile nonconventional lithographic patterning technique is developed for fabricating banks with microwell structures by inkjet printing solvent droplets onto a polymer layer, thereby locally dissolving the polymer to form microwells. The semiconductor ink is then inkjet‐printed into the microwells. In addition to confining the inkjet‐printed organic semiconductor droplets, the microwells provide a platform onto which organic semiconductor molecules crystallize during solvent evaporation. When printed onto the hydrophilic microwells, the inkjet‐printed 6,13‐bis(triisopropylsilylethynyl) pentacene (TIPS_PEN) molecules undergo self‐organization to form highly ordered crystalline structures as a result of contact line pinning at the top corner of the bank and the outward hydrodynamic flow within the drying droplet. By contrast, small crystallites form with relatively poor molecular ordering in the hydrophobic microwells as a result of depinning of the contact line along the walls of the microwells. Because pinning in the hydrophilic microwells occurred at the top corner of the bank, treating the surfaces of the dielectric layer with a hydrophobic organic layer does not disturb the formation of the highly ordered TIPS_PEN crystals. Transistors fabricated on the hydrophilic microwells and the hydrophobic dielectric layer exhibit the best electrical properties, which is explained by the solvent evaporation and crystallization characteristics of the organic semiconductor droplets in the microwell. These results indicate that this technique is suitable for patterning organic semiconductor deposits on large‐area flexible substrates for the direct‐write fabrication of high‐performance organic transistors.
A Highly Active and General Catalyst for the Stille Coupling Reaction of Unreactive Aryl, Heteroaryl, and Vinyl Chlorides under Mild Conditions

Published: June 2013

AbstractA β‐diketiminatophosphane‐palladium complex was found to act as an efficient and general catalyst in the Stille coupling reaction of various aryl and heteroaryl chlorides with organostannanes. The results show that this catalytic system allows for the use of less reactive substrates such as deactivated or sterically hindered aryl chlorides. A catalyst loading of 0.5 mol% was sufficient to achieve excellent performance under relatively mild reaction conditions. Furthermore, the scope of catalyst was extended to the coupling of vinyl chlorides.

Published: June 2013

AbstractBackgroundCoal mine dust exposure can cause both pneumoconiosis and chronic airflow limitation. The contributions of various pathophysiologic mechanisms to dust‐related lung function decrements remain unclear.MethodsClinical and physiological findings were assessed for 15 underground coal miners who had demonstrated accelerated FEV1 losses (decliners) over 6–18 years. Decliners' findings were evaluated in comparison to a group of 11 miners who had shown relatively stable lung function (referents) during the same period.ResultsAt follow‐up examination, the decliners showed significantly greater mean airway resistance (10.47 vs. 6.78 cmH2O/L/s; P = 0.05) and more air trapping (RV/TLC = 37.5 vs. 29.1%; P < 0.01) compared to the referents. Decliners also demonstrated more evidence of small airways dysfunction and tended to have more bronchospasm than the referent group. Total lung capacity, lung compliance, diffusing capacity, and chest radiography did not differ significantly between the two groups. After cessation of mine dust exposures, the decliners' mean rate of FEV1 loss normalized.ConclusionIn a series of working coal miners, accelerated lung function declines were associated with air trapping and evidence of small airways dysfunction. A preventive benefit from controlling dust exposures was suggested. Am. J. Ind. Med. 56:1107–1112, 2013. © 2013 Wiley Periodicals, Inc.

Published: June 2013

ObjectiveInflammatory arthritis is associated with systemic manifestations including alterations in metabolism. We used nuclear magnetic resonance (NMR) spectroscopy–based metabolomics to assess metabolic fingerprints in serum from patients with established rheumatoid arthritis (RA) and those with early arthritis.MethodsSerum samples were collected from newly presenting patients with established RA who were naive for disease‐modifying antirheumatic drugs, matched healthy controls, and 2 groups of patients with synovitis of ≤3 months' duration whose outcomes were determined at clinical followup. Serum metabolomic profiles were assessed using 1‐dimensional 1H‐NMR spectroscopy. Discriminating metabolites were identified, and the relationships between metabolomic profiles and clinical variables including outcomes were examined.ResultsThe serum metabolic fingerprint in established RA was clearly distinct from that of healthy controls. In early arthritis, we were able to stratify the patients according to the level of current inflammation, with C‐reactive protein correlating with metabolic differences in 2 separate groups (P < 0.001). Lactate and lipids were important discriminators of inflammatory burden in both early arthritis patient groups. The sensitivities and specificities of models to predict the development of either RA or persistent arthritis in patients with early arthritis were low.ConclusionThe metabolic fingerprint reflects inflammatory disease activity in patients with synovitis, demonstrating that underlying inflammatory processes drive significant changes in metabolism that can be measured in the peripheral blood. The identification of metabolic alterations may provide insights into disease mechanisms operating in patients with inflammatory arthritis.

Published: June 2013

ObjectivePulmonary hypertension (PH) is a frequent and life‐limiting complication of systemic sclerosis (SSc). However, data on survival rates and their evolution over time, as well as prognostic factors in SSc complicated by PH, are still conflicting. The aim of this study was to conduct a systematic review and meta‐analysis of cohort studies to assess pooled survival and prognostic factors for survival in patients with SSc–associated PH.MethodsFor this systematic review and meta‐analysis, we searched the Medline and EMBase databases (January 1960 to January 2012). All cohort studies in which survival and/or prognostic factors for SSc–associated PH were reported were included in the analysis. We calculated the pooled survival rates and analyzed their evolution over time and identified prognostic factors for survival.ResultsTwenty‐two studies were included, representing a total of 2,244 patients with SSc–associated PH. The pooled 1‐, 2‐, and 3‐year survival rates were 81% (95% confidence interval [95% CI] 79–84%), 64% (95% CI 59–69%), and 52% (95% CI 47–58%), respectively. Meta‐regression did not reveal a significant change in survival over time, while baseline hemodynamic measures of PH severity were significantly correlated with survival. In patients with SSc complicated by pulmonary arterial hypertension (PAH), age, male sex, diffusing capacity for carbon monoxide (DLCO), pericardial effusion, and the parameters classically associated with the severity of idiopathic PAH, including the 6‐minute walk distance, mean pulmonary artery pressure, cardiac index, and right atrial pressure, were significant prognostic factors. DLCO and pericardial effusion were the only prognostic factors in patients with interstitial lung disease–related PH.ConclusionOur meta‐analysis revealed a poor pooled 3‐year survival rate of 52% in patients with SSc–associated PH. Baseline hemodynamic measures of PAH severity, but not the period of time during which patients were included in the studies, correlated significantly with survival in patients with SSc–associated PAH. All of the prognostic factors typically observed in idiopathic PAH, including the 6‐minute walk distance and right atrial pressure, were also prognostic factors in SSc–associated PAH.

ObjectiveTo identify genetic determinants of granulomatosis with polyangiitis (Wegener's) (GPA).MethodsWe carried out a genome‐wide association study (GWAS) of 492 GPA cases and 1,506 healthy controls (white subjects of European descent), followed by replication analysis of the most strongly associated signals in an independent cohort of 528 GPA cases and 1,228 controls.ResultsGenome‐wide significant associations were identified in 32 single‐nucleotide polymorphic (SNP) markers across the HLA region, the majority of which were located in the HLA–DPB1 and HLA–DPA1 genes encoding the class II major histocompatibility complex (MHC) DPβ chain 1 and DPα chain 1 proteins, respectively. Peak association signals in these 2 genes, emanating from SNPs rs9277554 (for DPβ chain 1) and rs9277341 (DPα chain 1) were strongly replicated in an independent cohort (in the combined analysis of the initial cohort and the replication cohort, P = 1.92 × 10−50 and 2.18 × 10−39, respectively). Imputation of classic HLA alleles and conditional analyses revealed that the SNP association signal was fully accounted for by the classic HLA–DPB1*04 allele. An independent single SNP, rs26595, near SEMA6A (the gene for semaphorin 6A) on chromosome 5, was also associated with GPA, reaching genome‐wide significance in a combined analysis of the GWAS and replication cohorts (P = 2.09 × 10−8).ConclusionWe identified the SEMA6A and HLA–DP loci as significant contributors to risk for GPA, with the HLA–DPB1*04 allele almost completely accounting for the MHC association. These two associations confirm the critical role of immunogenetic factors in the development of GPA.
Comparing methods for design follow‐up: revisiting a metal‐cutting case study
Authors: Edwards David J. , Weese Maria L. , Palmer Gregory A. 
Published: June 2013

AbstractAdding another fraction to an initial fractional factorial design is often required to resolve ambiguities with respect to aliasing of factorial effects from the initial experiment and/or to improve estimation precision. Multiple techniques for design follow‐up exist; the choice of which is often made on the basis of the initial design and its analysis, resources available, experimental objectives, and so on. In this paper, we compare four design follow‐up strategies: foldover, semifoldover, D‐optimal, and Bayesian (MD‐optimal) in the context of a metal‐cutting case study previously utilized to compare fractional factorials of different run sizes. Follow‐up designs are compared for each of a , , and Plackett–Burman initial experiments. Our empirical results suggest that a single follow‐up strategy does not outperform all others in every situation. This case study serves to illustrate design augmentation possibilities for practitioners and provides some basis for the selection of a follow‐up experiment. Copyright © 2013 John Wiley & Sons, Ltd.
Mechanism of the Deprotonation Reaction of Alkyl Benzyl Ethers with n‐Butyllithium
Authors: Raposo M. Luz , Fernández‐Nieto Fernando , Garcia‐Rio Luis , Rodríguez‐Dafonte P. , Paleo M. Rita , Sardina F. Javier 
Published: June 2013

AbstractKinetic study of the α‐lithiation of benzyl methyl ether (BME) by nBuLi has revealed that increasing the concentration of the organolithium compound does not necessarily increase the reactivity, and this is a consequence of the reactivities of the different nBuLi aggregates present in solution. We propose a dimer‐based mechanism, in which a pre‐complexation step is a key process for substrates bearing a donor oxygen atom that can interact with the lithium cation to form mixed dimers. For these studies, we have developed a system based on UV/Vis spectroscopy that allows kinetic measurements to be conducted at −80 °C under argon.
