Este artigo tem por objetivo discutir como o conceito de dialogismo bakhtiniano está presente nas Orientações Curriculares de Língua Portuguesa para o Ensino Médio (OCEM - LP- MEC, 2006), documento reformulado pelo Ministério da Educação em 2006 a partir dos Parâmetros Curriculares Nacionais para o Ensino Médio (PCNEM- LP, MEC, 2000). Para análise do corpus, tomamos o dialogismo como constitutivo da linguagem, conforme propõe o Círculo de Bakhtin, mais especificamente Bakhtin/Volochinov (2006) e Bakhtin (2003). Esse trabalho se configura como uma pesquisa qualitativa de base interpretativista, de análise de documento e se insere no campo de estudos da linguagem. Os resultados apontam para uma proposta dialógica na perspectiva bakhtiniana em relação ao ensino de língua portuguesa.
Transitioning to nursing practice in Lebanon: Challenges in professional, occupational and cultural identity formation
Authors: Madi Murielle , Clinton Michael , Doumit Myrna , Ezzeddine Sawsan , Rizk Ursula 
Published: January 2018

The aim of this study was to identify the challenges graduates from three of Lebanon’s leading universities face as they transition from the role of student to first year registered nurse. Focus group discussions and one joint interview were conducted with 16 first year registered nurses transitioning to practice in university medical centers in Greater Beirut. Thematic analysis was used to summarize the challenges faced by the graduates. Initially, three descriptive themes were used to summarize the data: classroom learning, workplace realities, and “wanting a life”. Together the three themes indicted that classroom instruction of baccalaureate nursing students in Lebanon raises expectations for ideal practice that cannot be realized in clinical units with high workloads and nursing shortages. As a result, first year registered nurses are made to feel unwelcome unless they compromise their values and adapt quickly to the pace of work. The three initial themes were revised deductively from the perspective of ego-identity theory to explain the relationship between transitioning to nursing practice and identity formation in late adolescence and early adulthood. If the pressures of identity formation are not addressed, first year registered nurses in Lebanon will be at risk for acquiescing to task-centered practice, abandoning bedside care for administrative roles, or leaving nursing. The evidence for this conclusion will interest nursing faculty, hospital administrators, nurse leaders, registered nurses, physicians, and nursing students.

Published: January 2018

ABSTRACTHaving lost 60.8% of its population to migration and 93% of graduates with higher education by 2011, diaspora engagement may not be an option for Guyana in the future. Based on data collected from multiple sources and a review of the existent literature on diaspora engagement for development across the world, this paper seeks to unveil potentials and challenges that Guyana may face as it seeks to engage its diaspora for development. In addition to defining the Guyanese diaspora and reviewing interventions currently adopted by the government of Guyana for diaspora engagement, this paper also sheds light on concerns by Guyanese in the diaspora given the current political and socioeconomic conditions in Guyana and the challenges they face as efforts are made to contribute to Guyana´s development. Further, a review of interventions implemented by other countries around the world is presented with the focus of widening the options for Guyana. RESUMOCom base em dados coletados de múltiplas fontes e uma revisão da literatura existente sobre o envolvimento da diáspora para o desenvolvimento ao redor do mundo, este artigo busca revelar potenciais e desafios que a Guiana (um país de alta emigração) pode enfrentar, pois busca envolver sua diáspora para o desenvolvimento. Além de definir a diáspora da Guiana e revisar as intervenções atualmente adotadas pelo governo da Guiana para o engajamento da diáspora, este artigo também da luzes sobre as preocupações dos guianenses na diáspora, atendendo às condições políticas e socioeconômicas atuais na Guiana e aos desafios que enfrentam e os esforços realizados em busca do desenvolvimento. Além disso, uma revisão das intervenções implementadas em outros países ao redor do mundo é apresentada com o objetivo de ampliar as opções para a Guiana.Key words: Diaspora, Guyana, development
Desiccation resistance: effect of cuticular hydrocarbons and water content in Drosophila melanogaster adults
Authors: Ferveur Jean-Francois , Cortot Jérôme , Rihani Karen , Cobb Matthew , Everaerts Claude 
Published: January 2018

Background.The insect cuticle covers the whole body and all appendages and has bi-directionnal selective permeability: it protects against environmental stress and pathogen infection and also helps to reduce water loss. The adult cuticle is often associated with a superficial layer of fatty acid-derived molecules such as waxes and long chain hydrocarbons that prevent rapid dehydration. The waterproofing properties of cuticular hydrocarbons (CHs) depend on their chain length and desaturation number. Drosophila CH biosynthesis involves an enzymatic pathway including several elongase and desaturase enzymes.
Methods.The link between desiccation resistance and CH profile remains unclear, so we tested (1) experimentally selected desiccation-resistant lines, (2) transgenic flies with altered desaturase expression and (3) natural and laboratory-induced CH variants. We also explored the possible relationship between desiccation resistance, relative water content and fecundity in females.
Results.We found that increased desiccation resistance is linked with the increased proportion of desaturated CHs, but not with their total amount. Experimentally-induced desiccation resistance and CH variation both remained stable after many generations without selection. Conversely, flies with a higher water content and a lower proportion of desaturated CHs showed reduced desiccation resistance. This was also the case in flies with defective desaturase expression in the fat body.
Discussion. We conclude that rapidly acquired desiccation resistance, depending on both CH profile and water content, can remain stable without selection in a humid environment. These three phenotypes, which might be expected to show a simple relationship, turn out to have complex physiological and genetic links.
Interplanetary Magnetic Field Turbulence and Rigidity Spectrum of the Galactic Cosmic Rays Intensity Variation (1969–2011)

Published: December 2017

AbstractThe present study investigates the relation between the rigidity R spectrum exponent γ of the galactic cosmic rays (GCR) flux changes (δD(R)/D(R) ∝ R−γ) and the exponents νy and νz of the power spectral density of the By and Bz components of the heliospheric magnetic field (HMF) fluctuations. Two parameters have been introduced: (1) the exponent γ demonstrating the rigidity dependence of long‐term changes of GCR flux on solar activity (SA) and (2) the exponents νy and νz signifying the state of turbulence which is divided of the By and Bz components. This study considers the period of time between 1969 and 2011 divided into four subperiods, according to the solar global magnetic field polarities: (I) 1969–1979, (A > 0) (positive polarity magnetic field lines are directed away from the Sun's northern hemisphere); (II) 1980–1988, (A < 0) (negative polarity magnetic field lines are directed toward the Sun's northern hemisphere); (III) 1991–2001, (A > 0); and (IV) 2002–2011, (A < 0). The paper finds that temporal changes of the resonant frequency (fres) of GCR protons in heliospheric magnetic field turbulence in relation to SA are mainly caused by variations of the induction of B components from year to year, while the contribution of the solar wind speed remains insignificant. The analyses of the four subperiods show that γ increases and νy and νz decrease in the periods of increased SA, and conversely, the γ decreases and νy and νz increase in the periods of reduced SA. The study concludes that the exponents γ, and νy and νz can be considered as important indices (proxies) for research on GCR transport in the heliosphere.

Published: December 2017

ObjectiveOsteoarthritis (OA) is a heterogeneous disease, and symptom progression at the foot is unclear. This study investigated the symptomatic course of 3 predefined foot OA phenotypes over an 18‐month period.MethodsThe Clinical Assessment Study of the Foot is a community‐based cohort of adults ages ≥50 years in North Staffordshire, UK. Participants who reported foot pain in a postal health survey and underwent radiographic assessment were mailed an 18‐month followup survey. Changes in descriptive and symptomatic outcomes over 18 months were compared across the 3 phenotypes to determine within‐phenotype changes and between‐phenotype differences.ResultsOf 533 participants at baseline, 478 (89.7%) responded at 18 months. All 3 phenotypes showed small within‐phenotype improvements in mean foot pain severity (scale range 0–10, where 0 = no pain and 10 = worst pain): no or minimal foot OA (18 months 4.0, mean change −1.15 [95% confidence interval (95% CI) −1.46, −0.83]), isolated first metatarsophalangeal (MTP) joint OA (18 months 4.1, mean change −0.60 [95% CI −1.11, −0.10]), and polyarticular foot OA (18 months 5.1, mean change −0.77 [95% CI −1.42, −0.12]). The isolated first MTP joint OA phenotype had an increased likelihood of hallux valgus in the left foot (adjusted odds ratio 2.96 [95% CI 1.23, 7.12]) compared to the no or minimal foot OA phenotype.ConclusionThree foot OA phenotypes showed few descriptive or symptomatic changes over 18 months. Future clinical trials should consider that people recruited with mild‐to‐moderate symptomatic foot OA appear likely to remain relatively stable with usual care. Longer‐term followup using additional time points is required to describe further the natural history of foot OA.

Published: December 2017

ObjectiveKawasaki disease (KD) is an acute childhood vasculitis that may result in coronary aneurysms. Treatment of KD with a single infusion of 2 gm/kg intravenous immunoglobulin (IVIG) is well established, but acetylsalicylic acid (ASA) dose remains controversial. Our primary objective was to determine the difference in the incidence of IVIG resistance between 2 ASA doses. Our secondary objective was to compare the duration of hospital stay and the incidence of coronary artery aneurysm.MethodsWe reviewed charts of patients with KD from 2 Canadian centers to assess the impact of ASA dose on IVIG resistance (operationally defined as administration of a second dose of IVIG). Both centers used standard IVIG dosing, but center 1 used low‐dose ASA from diagnosis (3–5 mg/kg/day) while center 2 used initial high‐dose ASA (80–100 mg/kg/day).ResultsThere were no significant differences in baseline characteristics between the 2 centers. Retreatment with a second dose of IVIG was required in 28 of 122 patients (23%) treated with low‐dose ASA, and in 11 of 127 patients (8.7%) treated with high‐dose ASA in center 1 and center 2, respectively (P = 0.003). After adjusting for confounders, low‐dose ASA was associated with higher odds of IVIG resistance (OR 3.2 [95% confidence interval 1.1, 9.1]). The mean duration of hospital stay was 4.1 and 4.7 days, respectively (P = 0.37). Coronary artery aneurysms were seen in 2 of 117 and 6 of 125 patients from centers 1 and 2, respectively (P = 0.28).ConclusionLow‐dose ASA was associated with 3‐times higher odds of IVIG retreatment compared to high‐dose ASA, with no significant difference in duration of hospital stay or incidence of coronary artery aneurysms.
An All‐Dielectric Metasurface Building Block for the Kerker Effect between Excitons and Nanocavities: Germanium Nanogroove

Published: December 2017

AbstractCoupling between light and matter has many infusive physical effects and potential applications. Large Rabi splitting energy is achieved in many plasmonic nanostructures; however, these noble metallic materials generally suffer from a high level of Joule heating losses at optical frequencies. As an alternative strategy, all‐dielectric materials for manipulating light at the subwavelength scale have attracted enormous interest. However, the understanding of the interactions between all‐dielectric nanostructures and molecular excitons remains limited to date. Here, the use of a germanium nanogroove as a new all‐dielectric metasurface building block is demonstrated for the Kerker effect between molecular excitons and nanocavities. A distinct dip in the backward scattering spectra is observed, indicating relatively strong light–matter interaction due to the cavity magnetic resonance mode in the grooves. Germanium with a large real part and nonnegligible imaginary part of the refractive index in the visible region provides magnetic field enhancement similar to that of other all‐dielectric nanostructures; this phenomenon is theoretically explained by simulating the magnetic field distribution in the grooves. These findings may help researchers to better understand the interactions between all‐dielectric nanostructures and molecular excitons and indicate that germanium nanogrooves can potentially be used as metasurface building blocks in nanophotonic devices.
FLT3 inhibitors in acute myeloid leukemia: Choosing the best when the optimal does not exist
Authors: Assi Rita , Ravandi Farhad 
Published: December 2017

AbstractDespite significant advances in deciphering the molecular and cytogenetic pathways governing acute myeloid leukemia, improvements in treatment strategies and clinical outcomes have been limited. The discovery of FLT3 pathway and its potential role in leukemogenesis has generated excitement in the field and has provided a potential target for drug development. Despite setbacks encountered with first‐generation inhibitors, we are witnessing an outbreak of novel agents with potent activity and improved pharmacodynamics which continue to generate promising results. The disease, however, remains a challenge to both patients and physicians with rapid emergence of resistance and subsequent treatment failure. Multiple unanswered questions remain as to which are the optimal FLT3‐inhibitors and which strategies and combinations are likely to overcome resistance. This review revisits the development of FLT3‐inhibitors, the pathways incriminated in their failure and summarizes available molecularly‐designed strategies to design better clinical trials.

AbstractAchieving homogeneous dispersion of nanoporous fillers within membrane architectures remains a great challenge for mixed‐matrix membrane (MMMs) technology. Imparting solution processability of nanoporous materials would help advance the development of MMMs for membrane‐based gas separations. A mechanochemically assisted oxidative coupling polymerization strategy was used to create a new family of soluble nanoporous polymer networks. The solid‐state ball‐milling method affords inherent molecular weight control over polymer growth and therefore provides unexpected solubility for the resulting nanoporous frameworks. MMM‐based CO2/CH4 separation performance was significantly accelerated by these new soluble fillers. We anticipate this facile method will facilitate new possibilities for the rational design and synthesis of soluble nanoporous polymer networks and promote their applications in membrane‐based gas separations.

AbstractThe first dysprosium complexes with a terminal fluoride ligand are obtained as air‐stable compounds. The strong, highly electrostatic dysprosium–fluoride bond generates a large axial crystal‐field splitting of the J=15/2 ground state, as evidenced by high‐resolution luminescence spectroscopy and correlated with the single‐molecule magnet behavior through experimental magnetic susceptibility data and ab initio calculations.
