Sexo e as Negas: Empoderamento ou Reforço dos Estereótipos das Mulheres Negras na Mídia
Authors: Pereira Maia Camila , Jardim da Silva Roberto 
Published: April 2018

<p>O objetivo deste trabalho é analisar a minissérie “<em>Sexo e negas</em>”, que foi ao ar na <em>Rede Globo</em> no período de 16 de setembro de 2014 a 16 de dezembro deste mesmo ano. Ela conta a história de quatro amigas, mulheres negras da periferia do Rio de Janeiro, que almejam crescimento profissional e/ou buscam uma relação afetiva satisfatória. A iniciativa de analisar a minissérie se deu a partir do fato de que esta causou muita polêmica, sobretudo entre ativistas e intelectuais negras, que a acusavam de reforçar os estereótipos relacionados as mulheres negras. Assim, nossa análise visa abranger as seguintes questões: 1. A minissérie promove uma representação positiva das mulheres negras e as coloca em uma posição de protagonismo, como se propõe, ou apenas reforça os estereótipos que as envolvem, no imaginário social? 2. Como o corpo das mulheres negras é representado e qual o modelo de relação afetiva é conferido a elas? Como referência pra pensar a representatividade das pessoas negras na mídia será usado o pensamento de Joel Zito de Araújo. E para pensar a construção e reforço de estereótipos será usado o conceito de estigma de Erving Goffman. Para pensar a condição das mulheres negras no imaginário social brasileiro, usaremos como referência Suely Carneiro, Ana Cláudia Pacheco e Lélia Gonzalez. Constatou-se que a minissérie não foi capaz de romper com os estereótipos que envolvem as mulheres negras e seus corpos, assim como não foi capaz de colocá-las na posição de protagonistas, apenas reforçou os lugares sociais atribuídos a elas.</p>

Published: April 2018

AbstractGlynn et al. (2017, https://doi.org/10.1002/2016EF000487) note the importance of engaging stakeholders in the process of public policymaking and analysis. In particular, they highlight the central role biases, beliefs, heuristics, and values play in such engagement. However, the framework they propose neglects uncertainty, which significantly restricts any ability to engage effectively with BBHV. We show how their paper's narrow view can be widened to include aspects of risk and uncertainty.

Published: April 2018

AbstractThis paper introduces a slotted empty substrate integrated waveguide (ESIW) antenna for a multiple‐input multiple‐output (MIMO) radar sensor. The proposed system is based on the MIMO radar architecture. Orthogonal signals are sent from the transmitters, in such a manner that a MIMO image reconstruction is possible. The presented system application targets the surveillance of strategic areas in gas pipelines and nuclear plants. ESIW technology enables a high‐efficiency, low‐profile, and compact antenna for these MIMO systems. The fabricated device includes a transition to microstrip line, and, in consequence, the antenna can be integrated with the rest of the system in a standard integrated circuit. The slotted ESIW antenna design and measured results for the targeted application are presented in this paper. The measured results present a gain greater than 15 dBi and return loss below −13 dB over the targeted frequency band of operation (16–16.5 GHz). To the best of the authors' knowledge, this is the first slotted ESIW antenna reported in the scientific literature up to now.
The Water‐Energy Nexus of Hydraulic Fracturing: A Global Hydrologic Analysis for Shale Oil and Gas Extraction
Authors: Rosa Lorenzo , Rulli Maria Cristina , Davis Kyle Frankel , D'Odorico Paolo 
Published: April 2018

AbstractShale deposits are globally abundant and widespread. Extraction of shale oil and shale gas is generally performed through water‐intensive hydraulic fracturing. Despite recent work on its environmental impacts, it remains unclear where and to what extent shale resource extraction could compete with other water needs. Here we consider the global distribution of known shale deposits suitable for oil and gas extraction and develop a water balance model to quantify their impacts on local water availability for other human uses and ecosystem functions. We find that 31–44% of the world's shale deposits are located in areas where water stress would either emerge or be exacerbated as a result of shale oil or gas extraction; 20% of shale deposits are in areas affected by groundwater depletion and 30% in irrigated land. In these regions shale oil and shale gas production would likely compete for local water resources with agriculture, environmental flows, and other water needs. By adopting a hydrologic perspective that considers water availability and demand together, decision makers and local communities can better understand the water and food security implications of shale resource development.

AbstractOur different kinds of minds and types of thinking affect the ways we decide, take action, and cooperate (or not). The comment by Walker et al. (2018, https://doi.org/10.1002/2017EF000750) illustrates several points made by Glynn et al. (2017, https://doi.org/10.1002/2016EF000487) and many other articles. Namely, biases and beliefs often drive scientific reasoning, and scientists, just like other humans, are intimately attached to their values and heuristics. Scientists, just like many other people, also tend to read and interpret text in ways that best match their individual perceptions of a problem or issue: in many cases paraphrasing and changing the meaning of what they read to better match their initial ideas. Walker et al. are doing interesting and important research on uncertainty. Nonetheless, they misinterpret the work, assumptions, and conclusions brought forth by Glynn et al. (2017, https://doi.org/10.1002/2016EF000487).

AbstractEncapsulation of therapeutic cells in core–shell microparticles has great promise for the treatment of a range of health conditions. Unresolved challenges related to control of the particle morphology, mechanical stability, and immunogenicity hinder dissemination of this promising approach. Here, a novel polymer material for cell encapsulation and a combined novel, easy to control, synthesis method are introduced. Core–shell cell encapsulation is demonstrated with a concentric core–shell morphology formed during a single UV exposure, resulting in particles that consist of a synthetic hydrogel core of polyethylene glycol diacrylate and a solid, but porous, shell of off‐stoichiometric thiol‐ene. The encapsulated human cells in 100 µm diameter particles have >90% viability. The average shell thickness is controlled between 7 and 13 µm by varying the UV exposure, and the shell is measured to be permeable to low molecular weight species (<180 Da) but impermeable to higher molecular weight species (>480 Da). The unique material properties and the orthogonal control of the microparticle core size, shell thickness, shell permeability, and shell surface properties address the key unresolved challenges in the field, and are expected to enable faster translation of novel cell therapy concepts from research to clinical practice.

AbstractStony corals construct their aragonite skeleton by calcium carbonate precipitation, in a process recently suggested to be biologically controlled. Amorphous calcium carbonate and small amounts of calcite are also reported recently, however, their functional role is unknown. Coral acid‐rich proteins (CARPs) are extracted from the coral skeleton and are shown to be active in calcium carbonate precipitation in vitro. However, individual function of these proteins in coral mineralization is not known. Here, the regulatory activity of the aspartate‐rich CARP3 protein is examined. The whole protein and two peptides representing its acidic domain and its variable domain are used in CaCO3 precipitation reactions from Mg‐rich solutions. The biomolecules alter crystallization pathways, promoting Mg‐calcite in place of aragonite, with the acidic peptide capable of eradicating aragonite formation. The activity of CARP3 and its representative peptides is exerted from disordered CaCO3 mineral phases, coating the crystals formed, as shown by 2D 1H–13C heteronuclear correlation nuclear magnetic resonance (NMR) measurements, localizing organic protons in atomic proximity to disordered carbonate carbons. The structures of the protein and individual domains as derived from NMR measurements and folding calculations and their amino acid compositions are discussed in the context of their observed activity and its implication to mineralization in hard corals.
Interlayer Coupling Induced Infrared Response in WS2/MoS2 Heterostructures Enhanced by Surface Plasmon Resonance

Published: April 2018

AbstractInfrared light detection is generally limited by the intrinsic bandgap of semiconductors, which suppresses the freedom in infrared light photodetector design and hinders the development of high‐performance infrared light photodetector. In this work, for the first time infrared light (1030 nm) photodetectors are fabricated based on WS2/MoS2 heterostructures. Individual WS2 and MoS2 have no response to infrared light. The origin of infrared light response for WS2/MoS2 comes from the strong interlayer coupling which shrinks the energy interval in the heterojunction area thus rendering heterostructures longer wavelength detection ability compared to individual components. Considering the low light absorption due to indirect bandgap essence of few layers WS2/MoS2 heterostructures, its infrared responsivity is further enhanced with at most ≈25 times but the fast response rate is maintained via surface plasmon resonance (SPR). Such an interlayer coupling induced infrared light response and surface plasmon resonance enhancement strategy paves the way for high‐performance infrared light photodetection of infinite freedom in design.

Published: April 2018

AbstractFlexible smart surfaces with tunable wettability are promising for emerging wearable uses. However, currently, wearable superhydrophobic surfaces with dynamic wetting behaviors are rarely reported. Here, a skin‐like superhydrophobic elastomer surface with switchable lotus leaf and rose petal states is reported. Direct laser writing technique is employed for one‐step, programmable, large‐scale fabrication of monolithic and hierarchical micro‐nanostructures on elastomer, leading to strong water repellence. The surface topography can be finely regulated in a rapid and reversible manner by simple stretching, providing the feasibility of controlling the surface wettability by simple body motions. The ability to switch wetting states enables the surface to capture and release multiple droplets in parallel. Furthermore, the active surface can be applied to the joints of fingers and operate as a droplet manipulator under finger motions without requiring energy supply or external appliance. In this work, dynamic tuning of wetting properties is integrated into the design of skin‐like wearable surfaces, revealing great potential in versatile applications such as wearable droplet manipulator, portable actuator, adaptive adhesion control, liquid repellent skin, and smart clothing.
Phototunable Dielectric Huygens' Metasurfaces

Published: April 2018

AbstractConventional dielectric metasurfaces achieve their properties through geometrical tuning and consequently are static. Although some unique properties are demonstrated, the usefulness for realistic applications is thus inherently limited. Here, control of the resonant eigenmodes supported by Huygens' metasurface (HMS) absorbers through optical excitation is proposed and demonstrated. An intensity transmission modulation depth of 99.93% is demonstrated at 1.03 THz, with an associated phase change of greater than π/2 rad. Coupled mode theory and S‐parameter simulations are used to elucidate the mechanism underlying the dynamics of the metasurface and it is found that the tuning is primarily governed by modification of the magnetic dipole‐like odd eigenmode, which both lifts the degeneracy, and eliminates critical coupling. The dynamic HMS demonstrates wide tunability and versatility which is not limited to the spectral range demonstrated, offering a new path for reconfigurable metasurface applications.
Elastic Self‐Doping Organic Single Crystals Exhibiting Flexible Optical Waveguide and Amplified Spontaneous Emission
Authors: Huang Rui , Wang Chenguang , Wang Yue , Zhang Hongyu 
Published: April 2018

AbstractOrganic crystals are generally brittle and tend to crack under applied stress. Doped organic crystals are even more brittle because of lattice defects. Herein, the first doped organic crystals 1d@2d, which display elastic bending ability under applied stress, are reported. Moreover, the potential applications of elastic‐doped crystals 1d@2d in flexible optoelectronics are impressively demonstrated. The elastic crystals 1d@2d with high quality and large size are crystalized by a simple and unique “self‐doping” process, which is a regular solution evaporation of crude product 1d (2,5‐dihydro‐3,6‐bis(octylamino)terephthalate) containing a minute amount of 2d (3,6‐bis(octylamino)terephthalate) as the oxidized byproduct. The host 1d is easily crystallized to form elastic crystals but is nonfluorescent, while the guest 2d has poor crystallinity and is highly emissive. The doping approach integrates the advantages of both 1d and 2d, and thus endows doped crystals 1d@2d with good elasticity as well as intense orange fluorescence. Taking these advantages, the application potentials of these doped crystals 1d@2d are evaluated by measuring optical waveguide and amplified spontaneous emission in both the straight and bent states.
Metal‐Free Artificial Photosynthesis of Carbon Monoxide Using N‐Doped ZnTe Nanorod Photocathode Decorated with N‐Doped Carbon Electrocatalyst Layer

Published: April 2018

AbstractAn artificial photosynthesis system based on N‐doped ZnTe nanorods decorated with an N‐doped carbon electrocatalyst layer is fabricated via an all‐solution process for the selective conversion of CO2 to CO. Substitutional N‐doping into the ZnTe lattice decreases the bandgap slightly and improves the charge transfer characteristics, leading to enhanced photoelectrochemical activity. Remarkable N‐doping effects are also demonstrated by the N‐doped carbon layer that promotes selective CO2‐to‐CO conversion instead of undesired water‐to‐H2 reduction by providing active sites for CO2 adsorption and activation, even in the absence of metallic redox centers. The photocathode shows promising performance in photocurrent generation (−1.21 mA cm−2 at −0.11 VRHE), CO selectivity (dominant CO production of ≈72%), minor H2 reduction (≈20%), and stability (corrosion suppression). The metal‐free electrocatalyst/photocatalyst combination prepared via a cost‐effective solution process exhibits high performance due to synergistic effects between them, and thus may find application in practical solar fuel production.

Published: April 2018

BackgroundOlfactory‐specific quality of life (QOL) can be measured using the Questionnaire of Olfactory Disorders–Negative Statements (QOD‐NS), which examines various aspects of olfactory dysfunction. It is unknown if certain factors of the QOD‐NS differentially impact QOL.MethodsPatients with chronic rhinosinusitis (CRS) completed the QOD‐NS, 22‐item Sino‐Nasal Outcome Test (SNOT‐22), Medical Outcomes Study Short Form 6‐D (SF‐6D) health utility measure, and Patient Health Questionnaire‐2 (PHQ‐2) depression screen. Exploratory factor analysis of the QOD‐NS was performed. Associations between QOD‐NS factors and other QOL metrics were analyzed before and after endoscopic sinus surgery (ESS).ResultsOutcomes were examined on 132 patients. The QOD‐NS contains 4 distinct factors. There was no difference in associations between the different factors and baseline clinical characteristics. ESS had greatest effect size (d) on factors 2 and 4 (d = 0.29 and 0.27, respectively, p < 0.05). Postsurgical changes in the SF‐6D and SNOT‐22 had the strongest correlation with factor 2 scores (r = 0.29 and 0.34, respectively, p < 0.05), and changes in the PHQ‐2 had the strongest correlation to factor 3 (r = 0.24, p < 0.05). Abnormal QOD‐NS scores at baseline were associated with effect size increases of 50% to 100% (p < 0.05).ConclusionThe QOD‐NS measures 4 distinct factors. Eating‐related questions had the greatest improvement after ESS. Health utility and CRS‐specific QOL improvement most strongly associated with factor 2, while PHQ‐2 changes are most highly associated with factor 3, suggesting a differential impact of the factors of the QOD‐NS on varying aspects of QOL.
Partial resection of the middle turbinate during endoscopic sinus surgery for chronic rhinosinusitis does not lead to an increased risk of empty nose syndrome: a cohort study of a tertiary practice

Published: April 2018

BackgroundThe treatment of the middle turbinate (MT) during endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) remains a contentious issue with arguments both for and against its resection. The purpose of this study was to examine the clinical impact of partial MT resection (PMTR) during ESS, paying particular attention to the risk of developing empty nose syndrome (ENS) and alteration to olfaction.MethodsThis cohort study was performed on prospectively collected data. A total of 177 patients underwent ESS for CRS; 93 had PMTR and 84 MT preservation (MTP). Preoperative data collection included subjective symptom scores as per the Adelaide Disease Severity Score (ADSS), Lund‐Mackay scores, and nasal polyp status. The Empty Nose Syndrome 6‐Item Questionnaire (ENS6Q) was administered by telephone consultation and analyzed alongside postoperative symptom scores.ResultsThere was no difference in ENS6Q scores in patients who underwent PMTR vs those who had MTP. Patients who underwent PMTR had a higher baseline disease on Lund‐Mackay scoring, and were more likely to be nasal polyp patients and be undergoing revision surgery. ADSS scores demonstrated significant improvements in all rhinologic symptoms, with no difference between the cohorts.ConclusionPMTR is an adjunctive procedure to ESS. This study has established that PMTR as performed by the senior author carries no additional risk of developing ENS symptoms as defined by the ENS6Q, and that it carries no additional risk to olfaction or other rhinologic symptoms. PMTR can be safely considered at time of ESS, especially in patients at risk of lateralization of the MT.

Published: April 2018

AbstractAmphidinol 3 (AM3) is a marine natural product produced by the dinoflagellate Amphidinium klebsii. Although the absolute configuration of AM3 was determined in 1999 by extensive NMR analysis and degradation of the natural product, it was a daunting task because of the presence of numerous stereogenic centers on the acyclic carbon chain and the limited availability from natural sources. Thereafter, revisions of the absolute configurations at C2 and C51 were reported in 2008 and 2013, respectively. Reported herein is the revised absolute configuration of AM3: 32S, 33R, 34S, 35S, 36S, and 38S based on the chemical synthesis of partial structures corresponding to the C31–C67 fragment of AM3 in combination with degradation of the natural product. The revised structure is unique in that both antipodal tetrahydropyran counterparts exist on a single carbon chain. The structural revision of AM3 may affect proposed structures of congeners related to the amphidinols.
