“dia dos pais” inclui pais trans: Masculinidades dissidentes e práticas artísticas LGBTTQIA+
Authors: Baliscei João Paulo , Gonçalves Cleberson Diego 
Published: January 2021

Em 2020, próximo à data em que culturalmente se celebra o “dia dos pais” no Brasil, uma empresa nacional, popular na venda de cosméticos, convidou 14 homens para integrar uma campanha que valorizava pais presentes - dentre eles, Thammy Miranda (1982--), um homem transexual. A iniciativa gerou polêmica e divisão de opiniões, expondo, desse modo, ideias controversas não apenas sobre o “dia dos pais”, mas também sobre masculinidades não hegemônicas. A masculinidade hegemônica (CONNELL, 1990; 2016) se configura em uma concepção que descreve o “homem de verdade” como aquele que é imprescindivelmente atravessado pela cisgenereidade, pela heterossexualidade, pela branquitude, pela classe média-alta, pelos consumismos, pelo cristianismo e por demais marcadores identitários valorizados socialmente. Neste artigo, desempenhamos o objetivo de evidenciar as potencialidades das práticas artístico-acadêmicas LGBTTQIA+, na ampliação dos significados conferidos às masculinidades. Para tanto, primeiro debruçamo-nos especificamente sobre algumas das reações relacionadas à campanha em questão, e as aproximamos de conceitos específicos dos Estudos das Masculinidades e de Gênero a partir de uma abordagem construtivista. Após, a partir da metodologia da Pesquisa em Arte (REY, 1996) compartilhamos o processo criativo dos autores, professores-pesquisadores-artistas gays, em duas produções artísticas intituladas 2018 d.C (2020) e Super pai (2020). O tratamento e a intenção artística dados a essas produções, consideramos, problematizam e denunciam aspectos violentos da paternidade desempenhada por masculinidades hegemônicas, e reclamam pela ampliação de pontos de vistas e referências a partir dos quais representam-se visualmente as masculinidades nos espaços escolares.

La legibilidad en los informes de gestión: extensión y buenas prácticas de gobierno corporativo.
Este estudio expande el conocimiento sobre la legibilidad de los informes contables, su extensión y el cumplimiento de las empresas con las prácticas de buen gobierno. También cubre un vacío en el análisis de la legibilidad de la información narrativa escrita en español. Examinamos la legibilidad en los Informes de Gestión de las empresas españolas que cotizan en el Mercado Continuo de la Bolsa de Madrid durante el período 2010-2016. Los resultados revelan que los informes de gestión más extensos, es decir, aquellos con mayor cantidad de texto, son los menos legibles, y que el uso de elementos visuales en los informes ayuda a mejorar su legibilidad. Además, las empresas que siguen prácticas de buen gobierno, emiten información compleja con claridad, velocidad y simplicidad, lo que mejora la legibilidad de los informes contables.
This study expands our knowledge about the readability of accounting narratives, their extension and companies’ compliance with good governance practices. It also covers a gap in the analysis of the readability of narrative information written in Spanish. We examined the readability in Management Reports of Spanish companies listed on the Continuous Market of the Madrid Stock Exchange during the period 2010–2016. The results reveal that the most extensive management reports — that is, those with the greatest quantities of text — are the least readable and that the use of visual elements in reports helps to improve their readability. Moreover, companies that follow good governance practices issue complex information with clarity, speed, and simplicity, which improves the readability of accounting narratives.

Authors: Chesca Ana Claudia , Brandão Karina Damião , Mangucci Carolina Bragine 
Published: January 2021

Aims: The aim of this study was to investigate the microbiological quality and the presence of pathogens in sandwiches from different snack bars.
Study Design: Foods ready for consumption present a composition which facilitates their deterioration and care from production to consumption ensures its quality. The sandwich is a product of high consumption for its easy acquisition and despite its immediate consumption the sandwich can be considered a food offering risk to the consumers because it is composed of different ingredients that require excessive manipulation.
Place and Duration of Study: Food Microbiology Laboratory - University of Uberaba.
Methodology: For this study, 30 samples of this product were collected from the popular snack bars, street-foods and reputable fast-foods chains in Uberaba trade. The samples were transported to the Laboratory of Food Microbiology of the University of Uberaba in isotherm boxes filled with ice where they were kept under refrigeration until the time of analysis. The microbiological analyses were done according to the methods proposed by Vanderzant and Splittstoesser (1999) and Silva et al. (2007).
Results: From the total of the samples analyzed, 36.6% presented fecal coliforms and Salmonella sp.; 46.6% presented coagulase-positive Staphylococcus and 30% Bacillus cereus. There was no presence of sulphite-reducing clostridium.
Conclusion: The presence of coagulase-positive Staphylococcus aureus indicates the lack of hygiene by food handlers because it is a living microorganism from the nasopharynx and the presence of Salmonella sp. and fecal coliforms indicate poor hygiene and sanitary handling. The improper handling and lack of care in relation to good practices favor the food poisoning.
The Joy of Architecture: Evoking Emotions Through Building
Authors: Shearcroft Geoff 
Published: January 2021

AbstractGeoff Shearcroft – architect, architectural tutor, and director of London‐based AOC Architecture – opines that joy is crucial in architecture and that this joy is not about adherence to styles or prescribed spatial protocols, but emotional engagement. Joy propagated Postmodernism in the 1970s and 1980s, and so today, in another economically unstable time, it is re‐emerging, albeit differently.
Nanoparticle‐Based Activatable Probes for Bioimaging
Authors: Ma Tiancong , Xia Tian 
Published: January 2021

AbstractMolecular imaging can provide functional and molecular information at the cellular or subcellular level in vivo in a noninvasive manner. Activatable nanoprobes that can react to the surrounding physiological environment or biomarkers are appealing agents to improve the efficacy, specificity, and sensitivity of molecular imaging. The physiological parameters, including redox status, pH, presence of enzymes, and hypoxia, can be designed as the stimuli of the activatable probes. However, the success rate of imaging nanoprobes for clinical translation is low. Herein, the recent advances in nanoparticle‐based activatable imaging probes are critically reviewed. In addition, the challenges for clinical translation of these nanoprobes are also discussed in this review.
Ar/H2/O2‐Controlled Growth Thermodynamics and Kinetics to Create Zero‐, One‐, and Two‐Dimensional Ruthenium Nanocrystals towards Acidic Overall Water Splitting
Authors: Chen Ligang , Li Yaping , Liang Xin 
Published: January 2021

AbstractA gas controlled formation strategy is developed to synthesize free‐standing 0D Ru nanoparticles, 1D Ru nanowires, and 2D Ru nanosheets through in‐situ regulated growth thermodynamics and kinetics with typical inert, reductive, and oxidative gases (Ar/H2/O2). The growth process of these Ru nanoparticles, nanowires, and nanosheets follow non‐directional growth, shape‐directed nanoparticle attachment, and directional growth mechanisms, respectively. Kinetics studies approve that H2 accelerates the reduction rate of the Ru precursor, while O2 depresses the reduction. The calculation results of the Gibbs surface free energy under different gas coverage further show that small molecules’ gas can effectively regulate the surface state and growth rate. These Ru nanocrystals exhibit excellent acidic water splitting performance. This work has systematically studied the influence of the small molecule gas on the formation process of the Ru nanocrystals, and provides an effective idea for the development and research of high‐performance nanomaterials in the future.

AbstractReduction–oxidation (redox) reactions provide a distinct modality for biological communication that is fundamentally different from the more‐familiar ion‐based electrical modality. Biology uses these two modalities for communication through different systems (immune versus nervous), and uses different mechanisms to control the flow of the charge carriers: the flow of soluble ions is controlled using structural barriers (i.e., membranes) and gates (e.g., membrane‐spanning protein channels), while the flow of insoluble electrons is controlled using redox‐reaction networks. Here, a simple electrochemical approach to pattern catechols onto a flexible polysaccharide hydrogel is reported and it is demonstrated that the patterned catechol regions serve as nodes for the mediated flow of electrons through redox reactions. Electron flow through this node involves the switching of binary redox states (oxidized and reduced) and this node's redox state can be detected (i.e., “read”) by passively observing its optical absorbance, or actively switching its redox‐state electrochemically. Further, this catechol node can be switched through biological mechanisms, and this enables the fabricated catechol node to be embedded within biochemical redox reaction networks to facilitate the spanning of bio‐electronic communication. Thus, it is envisioned that catechols can emerge as a molecular equivalent to a transistor for miniaturize‐able, deployable and sustainable redox‐linked bioelectronics.
Induced Chiral Chromonics Confined in Micrometric Droplets

Published: January 2021

AbstractChirality emergence in biological systems is common but the chiral expression from the molecular to macroscopic level in water‐based systems is poorly understood. Among water‐based systems, chromonic liquid crystals have recently received a lot of attention due to the spontaneous chirality they show when confined in curved geometries. Confinement of chiral‐induced chromonics is not trivial since they are three component systems whose time stability is a delicate thermodynamic balance. In this work, a well‐defined periodic Frank–Pryce texture, typical of chiral thermotropic liquid crystals, is observed in microspheres of a chiral induced chromonic embedded in a poly(dimethylsiloxane) matrix. This texture slowly degrades in time and a possible mechanism behind the degradation process is suggested via X‐ray diffraction and atomic force microscopy measurements on thin chromonic films. To stabilize this texture and to control the structure periodicity, cations are added to the three components system in an attempt to tune the non‐covalent interactions between molecules and supramolecular stacks. The study of the effects of this addition allows for better insight into the molecular interactions that occur in the chiral induced mesophase. This is a crucial point in view of possible biocompatible technological applications.

AbstractA metal‐complex‐modified graphitic carbon nitride (g‐C3N4) bulk heterostructure is presented here as a promising alternative to high‐cost noble metals as artificial photocatalysts. Theoretical and experimental studies of the spectral and physicochemical properties of three structurally similar molecules Fo–D, Pt–D, and Pt–P confirm that the Pt(II) acetylide group effectively expands the electron delocalization and adjusts the molecular orbital levels to form a relatively narrow bandgap. Using these molecules, the donor–acceptor assemblies Fo–D@CN, Pt–D@CN, and Pt–P@CN are formed with g‐C3N4. Among these assemblies, the Pt(II) acetylide‐based composite materials Pt–D@CN and Pt–P@CN with bulk heterojunction morphologies and extremely low Pt weight ratios of 0.19% and 0.24%, respectively, exhibit the fastest charge transfer and best light‐harvesting efficiencies. Among the tested assemblies, 10 mg Pt–P@CN without any Pt metal additives exhibits a significantly improved photocatalytic H2 generation rate of 1.38 µmol h−1 under simulated sunlight irradiation (AM1.5G, filter), which is sixfold higher than that of the pristine g‐C3N4.

AbstractManipulating the thermal decomposition behavior of energetic materials is the key to further pushing the combustion performance of solid rocket propellants. Herein, atomically dispersed Pb single atoms on polydopamine (PDA‐Pb) are demonstrated, which display unprecedented catalytic activity toward the thermal decomposition of cyclotrimethylenetrinitramine (RDX). Impressively, RDX‐based propellants with the addition of PDA‐Pb catalyst exhibit substantially enhanced burning rates (14.98 mm s−1 at 2 MPa), which is 4.8 times faster than that without PDA‐Pb and represents the best catalytic performance among Pb‐based catalysts. Moreover, it also possesses low‐pressure exponents in broad pressure ranges, which can enable more stable and safer combustion in solid rocket engines. Theoretical calculation unravels the efficient catalytic activity is stemmed from the enhanced interfacial electronic coupling between RDX and PDA‐Pb via orbital level engineering. More importantly, PDA‐Pb also presents similar catalytic behavior toward the decomposition of nitrocellulose, suggesting its broad catalytic generality. This work can open up new opportunities in the field of energetic compound combustion by exploring Pb‐based single atom catalysts and beyond.

AbstractThe magnetic microrobots actuated by an external magnetic field can access distant, enclosed, and small spaces under fuel‐free conditions, which is apromising technology for manipulation and delivery under microenvironment; however, the complicated fabrication method limits their applications. Herein, three techniques including melt electrospinning writing (MEW), micromolding, and skiving process are combined to successfully mass‐produce tadpole‐like magnetic polycaprolactone/Fe3O4 (PCL/Fe3O4) microrobot. Importantly, the tadpole‐like microrobots under an external magnetic field can achieve two locomotions: rolling mode and propulsion mode. The rolling motion can approach the working destination quickly with a speed of ≈2 mm s−1. The propulsion motion (0−340 µm s−1) can handle a microcargo. Such a simple and cost‐effective production method shows a great potential for scale‐up fabrication of advanced shape‐design, mass‐production, and multifunctionality microrobot.
Food consumption and stigmatization under COVID‐19: Evidence from Chinese consumers’ aversion to Wuhan hot instant noodles
Authors: Hao Na , Wang H. Holly 
Published: January 2021

AbstractPandemics often lead to food stigma, and the coronavirus disease 2019 (COVID‐19) pandemic provides some evidence to this belief. Mitigating food stigma during the pandemic is vital for consumption replenishment and economic recovery and helping the stigmatized people. We conduct an empirical study to examine consumer behaviors using Wuhan hot instant noodles (WHINs), a packaged version of the famous Chinese dish reganmian, as a case study. Although WHIN's name and origin signify Wuhan, the epicenter of the pandemic, the noodles could be actually produced elsewhere, but since the COVID‐19 outbreak, WHIN has been avoided. On the basis of our results, we find that providing scientific information about the irrelevance between WHIN and the coronavirus is not effective in changing the minds of people with stigma. Moreover, stigma is more emotional than rational, especially among people with a lower self‐identified social class and poor psychological state. Therefore, psychological intervention programs may be warranted during pandemics to avoid potential stigmatization. The findings of this study could help to resolve the stigma affecting regional agriculture and the food economy. [EconLit citations: Q11, Q13].
Lack of biological mortality bias in the timing of dental formation in contemporary children: Implications for the study of past populations
Authors: Spake Laure , Hoppa Robert D. , Blau Soren , Cardoso Hugo F. V. 
Published: January 2021

AbstractObjectivesBiological mortality bias is the idea that individuals who perish (non‐survivors) are biologically distinct from those who survive (survivors). If biological mortality bias is large enough, bioarchaeological studies of nonsurvivors (skeletal samples) cannot accurately represent the experiences of the survivors of that population. This effect is particularly problematic for the study of juvenile individuals, as growth is particularly sensitive to environmental insults. In this study, we test whether biological mortality bias exists in one dimension of growth, namely dental development.Materials and methodsPostmortem computed tomography scans of 206 children aged 12 years and younger at death were collected from two institutions in the United States and Australia. The sample was separated into children dying from natural causes as proxies for non‐survivors and from accidental causes as proxies for survivors. Differences in the timing of dental development were assessed using sequential logistic regressions between dental formation stages and residual analysis of dental minus chronological age.ResultsNo consistent delay in age of attainment of dental stages was documented between survivors and non‐survivors. Delays between survivors and non‐survivors in dental relative to chronological age were greatest for infants, and were greater for females than for males.DiscussionLack of biological mortality bias in dental development reinforces confidence in juvenile age estimates and therefore in skeletal growth profiles and growth studies. As dental development is known to be less environmentally sensitive than skeletal growth and development, further studies should examine biological mortality bias in long bone length.

AbstractApproaches to achieve stable perovskite nanocrystals (PNCs) of interest, in particular those with large structural anisotropy, through protective coating of the inorganic shell at a single‐nanocrystal (NC) level are comparatively few and limited in scope. Reported here is a robust amphiphilic‐diblock‐copolymer‐enabled strategy for crafting highly‐stable anisotropic CsPbBr3 nanosheets (NSs) by in situ formation of a uniform inorganic shell (1st shielding) that is intimately ligated with hydrophobic polymers (2nd shielding). The dual‐protected NSs display an array of remarkable stabilities (i.e., thermal, photostability, moisture, polar solvent, aliphatic amine, etc.) and find application in white‐light‐emitting diodes. In principle, by anchoring other multidentate amphiphilic polymer ligands on the surface of PNCs, followed by templated‐growth of shell materials of interest, a rich variety of dual‐shelled, multifunctional PNCs with markedly improved stabilities can be created for use in optics, optoelectronics, and sensory devices.

ObjectiveBehçet’s disease is a complex systemic inflammatory vasculitis of incompletely understood etiology. This study was undertaken to investigate genetic associations with Behçet’s disease in a diverse multiethnic population.MethodsA total of 9,444 patients and controls from 7 different populations were included in this study. Genotyping was performed using an Infinium ImmunoArray‐24 v.1.0 or v.2.0 BeadChip. Analysis of expression data from stimulated monocytes, and epigenetic and chromatin interaction analyses were performed.ResultsWe identified 2 novel genetic susceptibility loci for Behçet’s disease, including a risk locus in IFNGR1 (rs4896243) (odds ratio [OR] 1.25; P = 2.42 × 10−9) and within the intergenic region LNCAROD/DKK1 (rs1660760) (OR 0.78; P = 2.75 × 10−8). The risk variants in IFNGR1 significantly increased IFNGR1 messenger RNA expression in lipopolysaccharide‐stimulated monocytes. In addition, our results replicated the association (P < 5 × 10−8) of 6 previously identified susceptibility loci in Behçet’s disease: IL10, IL23R, IL12A‐AS1, CCR3, ADO, and LACC1, reinforcing the notion that these loci are strong genetic factors in Behçet’s disease shared across ancestries. We also identified >30 genetic susceptibility loci with a suggestive level of association (P < 5 × 10−5), which will require replication. Finally, functional annotation of genetic susceptibility loci in Behçet’s disease revealed their possible regulatory roles and suggested potential causal genes and molecular mechanisms that could be further investigated.ConclusionWe performed the largest genetic association study in Behçet’s disease to date. Our findings reveal novel putative functional variants associated with the disease and replicate and extend the genetic associations in other loci across multiple ancestries.
