De nós para você para mim: a co-construção da identidade nas interações iniciais
Authors: Parker-Rees Rod 
Published: August 2015

Desde uma perspectiva histórico-cultural, a relação entre os processos interpsíquicos de interação social “pública” e os processos intrapsíquicos de pensamento “privado” é complexa e recíproca. Embora se possa dizer que a identidade emerge a partir de um “nós” primário, também é possível argumentar que só somos capazes de desenvolver aautoconsciência porque internalizamos formas de interação que são inicialmente vividas entre as pessoas. Neste artigo, será considerada como a construção compartilhada da identidade pode ser entendida em termos de uma habilidade em desenvolvimento para participar do fluxo de informações oferecidas por interações sociais. Argumenta-se que as interações sociais fornecem oportunidades para aprender muito mais sobre outras pessoas (e sobre nós mesmos) do que é acessível à nossa percepção consciente.
A escola e a exploração do trabalho infantil na fumicultura catarinense
Authors: Conde Soraya Franzoni , Vendramini Célia Regina 
Published: August 2015

O objetivo deste artigo é refletir sobre as relações entre a escola e a exploração do trabalho infantil no contexto da fumicultura catarinense, considerando as particularidades e os aspectos universais a que os trabalhadores do campo estão submetidos. A pesquisa foi realizada em 11 escolas, com a participação de 1080 crianças e adolescentes dos municípios catarinenses de São Bonifácio, Imbuia e Canoinhas. Observou-se que a existência de uma tênue fronteira entre o trabalho da criança e aajuda à organização da vida familiar é um elemento fundamental das atuais formas de exploração e generalização do trabalho coletivo. Dessa forma, o lugar ocupado pela escola no campo vai além do ensino e da quali( cação necessária ao trabalho nasociedade capitalista. A escola e as unidades de educação infantil são também, dialeticamente, o local do não trabalho, onde as crianças e os adolescentes são poupados da labuta diária, encontram colegas da mesma idade, brincam, aprendem e descansam.
Escisión al interior de la pandilla Barrio 18 en El Salvador: Una mirada antropológica
Authors: Amaya Luis Enrique , Martínez Juan José 
Published: August 2015

Este artículo tiene por objetivo general examinar y analizar preliminarmente, el proceso a través del cual se dividió la pandilla Barrio 18 en “los Sureños” y “los Revolucionarios”. La metodología empleada se ha basado en la aplicación de las técnicas de revisión documental y entrevistas en profundidad. Este trabajo arranca de un esfuerzo previo, en el que, con una visión holística, se entiende a las maras o pandillas apartir de cuatro criterios: 1) Su forma organizacional; 2) Su composición; 3) La naturaleza de sus acciones; y 4) Su conjunto de valores y normas socioculturales. La definición de pandilla como categoría en clave de identidad resulta esencial. La necesidad de construir una definición holística de pandilla tiene el objetivo de evitar “suavizar” el accionar delictivo de los pandilleros, así como “sobre-criminalizar”a las pandillas.Revista Policía y Seguridad Pública 5(1) 2015: 149-178
Recuperar el control estatal en territorio de la Mara Salvatrucha: un análisis a partir del acuerdo “Santa Tecla Municipio Libre de Violencia”
Authors: Zoethout Margriet Antoinette 
Published: August 2015

Este artículo presenta la primera parte de una investigación más amplia sobre el control social y territorial de la Mara Salvatrucha en la colonia San José del Pino y la comunidad San Rafael, ambas del municipio de Santa Tecla. En un estudio de caso en el marco de una Maestría en Estudios Latinoamericanos en la Universidad de Ámsterdam, se han mapeado los efectos de las políticas preventivas de seguridad pública en la zona, con énfasis en la estrategia “Santa Tecla Municipio Libre de Violencia” (MLV). El artículo analiza los efectos del proceso de pacificación, generado a partir de 2012 con la implementación de la filosofía de policía comunitaria y la estrategia MLV, para el tejido social y el sostenimiento local en las comunidades mencionadas. También se evalúa la recuperación de la gobernanza local después de décadas de ausencia estatal en la zona. Como resultado de las nuevas políticas de seguridad pública, los índices de delincuencia han bajado, el temor ha disminuido, el sostenimiento local ha mejorado, y valores y redes sociales están reestablecidas. Sin embargo, es necesario crear una política de seguridad pública que le dé sostenimiento a mediano y largo plazo a las demandas y necesidades del sector, independientemente de quién gobierne el municipio; este esfuerzo no puede detenerse si se quieren resultados positivos.Revista Policía y Seguridad Pública 5(1) 2015: 179-246
Las drogas ilícitas en el conflicto armado de Colombia y el tema en la firma del acuerdo de paz: pasado, presente y futuro
Authors: Baracaldo Méndez María Stella 
Published: August 2015

La historia reciente de Colombia se ha caracterizado por la violencia motivada, fundamentalmente, por la concentración del poder político-económico en menos del 20 % de la población y la presencia de los “Señores de la Guerra” vinculados con narcotráfico. El procesamiento de cocaína para exportación fue un negocio promovido por estadounidenses en los años setenta y representa la mayor “bonanza económica ilegal” experimentada por el país. Este “oro blanco” es “la fuente de una larga serie de profundos y permanentes conflictosy procesos sociales y políticos que de alguna forma han conmocionado las bases de esta sociedad y los aparatos institucionales que la rigen” (Camacho Guizado, 1988). El narcotráfico ha beneficiado a muchos –guerrilleros, paramilitares, mafiosos y mercenarios de los EE. UU.–, pero también ha dejado numerosas víctimas que no han recibido reparación así como criminales en la impunidad. En el 2015, Colombia busca decididamente firmar el acuerdo para la paz, dentro del cual las drogas ilícitas serán asunto de salud pública y, con seguridad, de legalización.Revista Policía y Seguridad Pública 5(1) 2015: 301-352
Turoctocog alfa (recombinant factor VIII)
Authors: Klamroth R. , Oldenburg J. , Tiede A. 
Published: August 2015

SummaryTuroctocog alfa (NovoEight®) is a new recombinant factor VIII (rFVIII) with a truncated B domain and a high degree of tyrosine sulphation, similar to plasma-derived FVIII products. The manufacturing process includes double nanofiltration with a 20-nm pore size and immunoaffinity chromatography with monoclonal F25 anti-FVIII antibodies. Treatment with turoctocog alfa can be monitored with both one-stage and chromogenic substrate assays without a product-specific laboratory standard. In total, 213 previouslytreated patients with severe haemophilia A participated in the pivotal part of the clinical trial programme guardianTM. The median annualised bleeding rate during turoctocog alfa prophylaxis was 3.7 and 3.0 in adolescents/adults and children, respectively, with marked differences between participating countries. The success rate for the treatment of breakthrough bleeds was 85% (adults/ adolescents) and 94% (children). A total of 41 surgical procedures (15 major, 26 minor) were performed in 33 patients, with a successful haemostatic response reported in all cases. No patient developed confirmed inhibitors in any of the trials.

Abstract

Mesenchymal stem cells (MSCs) of placental origin have become increasingly translational owing to their abundance and accessibility. MSCs of different origin share several features but also present biological differences that might point to distinct clinical properties. Hence, mixing fetal and maternal cells from the same placenta can lead to contradicting results. We analyzed the biological characteristics of haploidentical MSCs isolated from fetal sources, including the umbilical cord (UC-MSCs) and chorion (Ch-MSCs), compared with maternal decidua MSCs (Dc-MSCs). All MSCs were analyzed for general stem cell properties. In addition, immunosuppressive capacity was assessed by the inhibition of T-cell proliferation, and angiogenic potential was evaluated in a Matrigel transplantation assay. The comparison between haploidentical MSCs displayed several distinct features, including (a) marked differences in the expression of CD56, (b) a higher proliferative capacity for Dc-MSCs and UC-MSCs than for Ch-MSCs, (c) a diversity of mesodermal differentiation potential in favor of fetal MSCs, (d) a higher capacity for Ch-MSCs to inhibit T-cell proliferation, and (e) superior angiogenic potential of Ch-MSCs evidenced by a higher capability to form tubular vessel-like structures and an enhanced release of hepatocyte growth factor and vascular endothelial growth factor under hypoxic conditions. Our results suggest that assessing the prevalence of fetomaternal contamination within placental MSCs is necessary to increase robustness and limit side effects in their clinical use. Finally, our work presents evidence positioning fetoplacental cells and notably Ch-MSCs in the forefront of the quest for cell types that are superior for applications in regenerative medicine.

Significance
This study analyzed the biological characteristics of mesenchymal stem cells (MSCs) isolated from fetal and maternal placental origins. The findings can be summarized as follows: (a) important differences were found in the expression of CD56, (b) a different mesodermal differentiation potential was found in favor of fetal MSCs, (c) a higher immunosuppressive capacity for chorion MSCs was noted, and (d) superior angiogenic potential of Ch-MSCs was observed. These results suggest that assessing the prevalence of fetomaternal contamination within placental MSCs is necessary to increase robustness and limit side effects in their clinical use. The evidence should allow clinicians to view fetoplacental cells, notably Ch-MSCs, favorably as candidates for use in regenerative medicine.
L’adaptation cinématographique d’oeuvres théâtrales chez Jean Cocteau
Authors: El Gharbie Rana 
Published: August 2015

Jean Cocteau adapte à l’écran trois de ses pièces : L’Aigle à deux têtes en 1947, Les Parents terribles en 1948 et Orphée en 1950. À travers la structure de leur intrigue, leur langage, leurs décors et un jeu de mise en abyme, les deux premières adaptations affichent une théâtralité qui les apparente. Mais elles se distinguent en ce que leur degré d’utilisation des techniques cinématographiques, et par conséquent la profondeur de leur pouvoir de théoriser le rapport liant le théâtre et le septième art, diffère significativement. De plus, l’écriture cinématographique se révèle en elles essentiellement par le changement de l’échelle des plans et la variation des angles. Or, Cocteau réussit pleinement sa deuxième pièce filmée, puisque la caméra y joue le rôle d’un spectateur, qui se déplace librement sur une scène de théâtre. Avec Orphée, le poète détourne la source théâtrale de son film en multipliant les intrigues, les actions et les décors extérieurs. Plus encore, il recourt à nombre de trucages fabriqués et d’artifices que permet le montage. Ces astuces cinématographiques témoignent parfaitement du réalisme irréel tant recherché par Cocteau. L’adaptation de pièces en films permet donc à l’auteur d’explorer l’art de l’artifice afin de mettre en scène l’invisibilité et de déjouer son statut de poète inconnu et incompris. C’est ce que nous verrons dans cet article.
Ce qui reste du théâtre dans le film : le « cas » Marguerite Duras
Authors: Beaulieu Julie 
Published: August 2015

Examiner les aspects formels du théâtre durassien facilite la compréhension du système filmique non conventionnel de Marguerite Duras, car bien avant de se livrer à la pratique du cinéma, l’écrivaine s’est consacrée à la littérature, puis au théâtre. Dans le texte dramatiqueLa Musica(créé en 1965), des éléments cinématographiques attirent d’emblée l’attention. De fait, sa mise en scène préfigure celle d’un cinéma à venir, appuyé sur une rupture entre la bande sonore et les images — une mise en scène cinématographique dont seuls les personnages principaux, une femme et un homme ordinaires, seront présents sur scène, dans un décor minimaliste qui annonce la future « disparition » des personnages aux yeux du spectateur. Quelques meubles et des décorations placés ici et là serviront d’assise aux voix, celles-là mêmes qui donneront naissance au cinéma durassien — un cinéma de la littérature, tel que le suggérait Dominique Noguez, un cinéma de la parole. Notre article propose donc une réflexion sur le rapport singulier qu’entretiennent le texte dramatique et le cinéma dans le contexte de l’adaptation filmique, et plus spécifiquement de la réécriture, qui se situe au carrefour des pratiques, des genres et des discours.
Un cinéma sous influence : Le Soulier de satin de Manoel de Oliveira
Authors: Gonçalves Luís Carlos Pimenta 
Published: August 2015

Le réalisateur portugais Manoel de Oliveira, en activité jusqu’à son décès à 106 ans, s’est très tôt intéressé au théâtre et à la représentation non réaliste qui se trouve aux antipodes du travail de l’Actors Studio. Il a adapté au cinéma certaines oeuvres d’auteurs portugais, comme Camilo Castelo Branco, un romancier du XIXe siècle, ou encore, parmi les écrivains du XXe siècle, José Régio ou Raul Brandão, un dramaturge dont le cinéaste a interprété O Gebo e a Sombra (Gebo et l’ombre), qui a été présenté au Festival international du film de Venise, hors compétition, en 2012. Manoel de Oliveira a, par ailleurs, aussi bien réalisé des films à partir de textes d’auteurs français : de Flaubert (selon une réinterprétation de la romancière Agustina Bessa-Luís), de Madame de Lafayette ou de Claudel. Dans cet article, nous nous intéresserons tout particulièrement à une adaptation réalisée en français, Le Soulier de satin, qui s’approprie la pièce du même titre écrite par Paul Claudel. D’une durée de sept heures, le film reprend l’essentiel du texte claudélien et a été montré en avant-première en 1985, dans une salle de théâtre. Nous nous interrogerons ici sur le passage du théâtre à un cinéma non réaliste, qui garde bien visibles tous les artéfacts, tous les artifices, toutes les conventions propres à l’art dramatique.
Hürthle cell adenoma diagnosed by core needle biopsy in a male patient

Published: August 2015

Abstract
Huuml;rthle cell adenomas (HCAs) are a rare and potentially lethal variant of follicular tumors of the thyroid. Considerable controversy exists regarding potential risk factors, diagnosis, and treatment of HCAs. The authors report the case of a 38-year-old male patient with an 8.3 cm x 3.5 cm HCA. Diagnosis was made preoperatively from a core needle biopsy and confirmed postoperatively on frozen section. Treatment consisted of a right lobectomy.
Whither field hydrology? The need for discovery science and outrageous hydrological hypotheses
Authors: Burt T. P. , McDonnell J. J. 
Published: August 2015

AbstractField hydrology is on the decline. Meanwhile, the need for new field‐derived insight into the age, origin and pathway of water in the headwaters, where most runoff is generated, is more needed than ever. Water Resources Research (WRR) has included some of the most influential papers in field‐based runoff process understanding, particularly in the formative years when the knowledge base was developing rapidly. Here we take advantage of this 50th anniversary of the journal to highlight a few of these important field‐based papers and show how field scientists have posed strong and sometimes outrageous hypotheses—approaches so needed in an era of largely model‐only research. We chronicle the decline in field work and note that it is not only the quantity of field work that is diminishing but its character is changing too: from discovery science to data collection for model parameterization. While the latter is a necessary activity, the loss of the former is a major concern if we are to advance the science of watershed hydrology. We outline a vision for field research to seek new fundamental understanding, new mechanistic explanations of how watershed systems work, particularly outside the regions of traditional focus.
High emission rate of sulfuric acid from Bezymianny volcano, Kamchatka
Authors: Zelenski Michael , Taran Yuri , Galle Bo 
Published: August 2015

AbstractHigh concentrations of primary sulfuric acid (H2SO4) in fumarolic gases and high emission rate of sulfuric acid aerosol in the plume were measured at Bezymianny volcano, an active dome‐growing andesitic volcano in central Kamchatka. Using direct sampling, filter pack sampling, and differential optical absorption spectroscopy measurements, we estimated an average emission of H2SO4 at 243 ± 75 t/d in addition to an average SO2 emission of 212 ± 65 t/d. The fumarolic gases of Bezymianny correspond to arc gases released by several magma bodies at different stages of degassing and contain 25–92% of entrained air. H2SO4 accounts for 6–87 mol% of the total sulfur content, 42.8 mol% on average, and SO2 is the rest. The high H2SO4 in Bezymianny fumaroles can be explained by catalytic oxidation of SO2 inside the volcanic dome. Because sulfate aerosol is impossible to measure remotely, the total sulfur content in a plume containing significant H2SO4 may be seriously underestimated.
Solar wind conditions leading to efficient radiation belt electron acceleration: A superposed epoch analysis

AbstractDetermining preferential solar wind conditions leading to efficient radiation belt electron acceleration is crucial for predicting radiation belt electron dynamics. Using Van Allen Probes electron observations (>1 MeV) from 2012 to 2015, we identify a number of efficient and inefficient acceleration events separately to perform a superposed epoch analysis of the corresponding solar wind parameters and geomagnetic indices. By directly comparing efficient and inefficient acceleration events, we clearly show that prolonged southward Bz, high solar wind speed, and low dynamic pressure are critical for electron acceleration to >1 MeV energies in the heart of the outer radiation belt. We also evaluate chorus wave evolution using the superposed epoch analysis for the identified efficient and inefficient acceleration events and find that chorus wave intensity is much stronger and lasts longer during efficient electron acceleration events, supporting the scenario that chorus waves play a key role in MeV electron acceleration.
On solar geoengineering and climate uncertainty
Authors: MacMartin Douglas G. , Kravitz Ben , Rasch Philip J. 
Published: August 2015

AbstractUncertain climate system response has been raised as a concern regarding solar geoengineering. We explore the effects of geoengineering on one source of climate system uncertainty by evaluating the intermodel spread across 12 climate models participating in the Geoengineering Model Intercomparison project. The model spread in simulations of climate change and the model spread in the response to solar geoengineering are not additive but rather partially cancel. That is, the model spread in regional temperature and precipitation changes is reduced with CO2 and a solar reduction, in comparison to the case with increased CO2 alone. Furthermore, differences between models in their efficacy (the relative global mean temperature effect of solar versus CO2 radiative forcing) explain most of the regional differences between models in their response to an increased CO2 concentration that is offset by a solar reduction. These conclusions are important for clarifying geoengineering risks regarding uncertainty.
Ion acceleration dependence on magnetic shear angle in dayside magnetopause reconnection
Authors: Vines S. K. , Fuselier S. A. , Trattner K. J. , Petrinec S. M. , Drake J. F. 
Published: August 2015

AbstractMagnetic reconnection at the Earth's magnetopause plays an important role in magnetospheric dynamics. Understanding the dynamics requires theory and observations. Previous theoretical work suggests that for no guide field, ions in the exhaust region on the magnetosheath side of the boundary counterstream with a velocity separation that is twice the upstream Alfvén speed (vA) and that the counterstreaming velocity decreases with increasing guide field. These theoretical predictions are tested for reconnection at the Earth's magnetopause using observations from the Cluster spacecraft. The difference between the incident and reflected ion velocities (vsep) in the magnetosheath boundary layer ion populations is used to determine the exhaust velocity. The ratio of vsep over twice the Alfvén speed (RV = vsep/2vA,L) is predicted to approach 1 for reconnection with shear angles near 180° (no guide field) but is observed to reach a value of approximately 0.84 for the magnetopause crossings analyzed with shear angles near 180°. This value is consistent with previous observations of ion velocities from reconnection at the magnetopause investigated using the Walén relation. While magnetic shear angle can contribute to the disagreement between observations and the Walén relation, it does not play a large role, given the reduced ratio for the events near 180° in this study.
The 3 May 2006 (Mw 8.0) and 19 March 2009 (Mw 7.6) Tonga earthquakes: Intraslab compressional faulting below the megathrust

Published: August 2015

AbstractThe Tonga subduction zone is among the most seismically active regions and has the highest plate convergence rate in the world. However, recorded thrust events confidently located on the plate boundary have not exceeded Mw 8.0, and the historic record suggests low seismic coupling along the arc. We analyze two major thrust fault earthquakes that occurred in central Tonga in 2006 and 2009. The 3 May 2006 Mw 8.0 event has a focal mechanism consistent with interplate thrusting, was located west of the trench, and caused a moderate regional tsunami. However, long‐period seismic wave inversions and finite‐fault modeling by joint inversion of teleseismic body waves and local GPS static offsets indicate a slip distribution centered ~65 km deep, about 30 km deeper than the plate boundary revealed by locations of aftershocks, demonstrating that this was an intraslab event. The aftershock locations were obtained using data from seven temporary seismic stations deployed shortly after the main shock, and most lie on the plate boundary, not on either nodal plane of the deeper main shock. The fault plane is ambiguous, and investigation of compound rupture involving coseismic slip along the megathrust does not provide a better fit, although activation of megathrust faulting is responsible for the aftershocks. The 19 March 2009 Mw 7.6 compressional faulting event occurred below the trench; finite‐fault and W‐phase inversions indicate an intraslab, ~50 km deep centroid, with ambiguous fault plane. This event also triggered small megathrust faulting. There continues to be a paucity of large megathrust earthquakes in Tonga.
