Documentário, reportagem e alteridade: a questão ética na simbolização do Outro//Documentary, report and otherness: an ethical issue in the Other symbolization
Authors: Salvo Fernanda Ribeiro 
Published: May 2023

Nesse artigo buscaremos tecer algumas aproximações entre o universo do documentário e aquele da reportagem. Não pretendemos igualar os dois gêneros, mas reivindicamos a não-polarização de alguns aspectos, sobretudo, no que diz respeito à questão ética que se impõem na inscrição da alteridade. Sabemos que tanto o documentário quanto a reportagem são espaços de simbolização do Outro e possuem legitimidade para apresentar os sujeitos, os povos, os espaços e diversas formas de alteridade, cumprindo uma função social. Refletir sobre o gesto ético esboçado pelas narrativas textuais e imagéticas nos parece tarefa fundamental, pois as representações do Outro entram nas disputas pelo sensível, confrontando e sendo confrontadas por heterogêneas forças e poderes advindos do mundo social. Em nosso percurso, discutiremos o modo como a particularidade ética do documentário está atrelada de modo essencial à escritura fílmica. No caso da reportagem, consideraremos como a narrativa em primeira pessoa e a reflexividade podem configurar-se como saída ética na construção da alteridade. Para melhor caracterizar tal perspectiva, comentamos brevemente o livro O nascimento de Joicy (2015), de Fabiana Moraes.

This paper seeks to mention some approaches between the universe of the documentary and that one of the documentary. We do not wish to equate the two genres, but claim the non-polarization of some aspects, especially with regard to the ethical question required on registration of otherness. We know that both the documentary as the story are the other symbolizing spaces and have legitimacy to introduce the subject, people, spaces and various forms of otherness, fulfilling a social function. We know that both the documentary as the report are the Other symbolizing spaces and have legitimacy to introduce the subjects, the people, the spaces and various forms of otherness, fulfilling a social function.
It seems to us fundamental task to reflect on the ethical gesture outlined by the textual and imagistic narratives, because the representations of the Other are in the disputes for the sensitive, confronting and being confronted by heterogeneous forces and powers from the social world. In our course, we will discuss how the ethical particularities of the documentary are tied essentially to the filmic document. In the case of the report we consider how the first-person narrative and the reflexivity can be configured as an ethical output in the construction of otherness. To better characterize such a perspective, we briefly comment on the book “The birth of Joicy” (2015), Sandesh by Fabiana Moraes.

ImportanceA correlation between antibody levels and risk of infection has been demonstrated for the wild-type, Alpha, and Delta SARS-COV-2 variants. High rates of breakthrough infections by the Omicron variant emphasized the need to investigate whether the humoral response elicited by mRNA vaccines is also associated with reduced risk of Omicron infection and disease.ObjectiveTo investigate whether the high antibody levels in individuals who have received at least 3 doses of an mRNA vaccine are associated with reduced risk of Omicron infection and disease.Design, Setting, and ParticipantsThis prospective cohort study used serial real time–polymerase chain reaction (RT-PCR) and serological test data from January and May 2022 to assess the association of preinfection immunoglobin G (IgG) and neutralizing antibody titers with incidence of Omicron variant infection, incidence of symptomatic disease, and infectivity. Participants included health care workers who had received 3 or 4 doses of an mRNA COVID-19 vaccine. Data were analyzed from May to August 2022.ExposuresLevels of SARS-CoV-2 anti–receptor binding domain IgG and neutralizing antibodies.Main Outcomes and MeasuresThe main outcomes were incidence of Omicron infection, incidence of symptomatic disease, and infectivity. Outcomes were measured using SARS-COV-2 PCR and antigen testing and daily online surveys regarding symptomatic disease.ResultsThis study included 3 cohorts for 3 different analyses: 2310 participants were included in the protection from infection analysis (4689 exposure events; median [IQR] age, 50 [40-60] years; 3590 [76.6%] among female health care workers), 667 participants (median [IQR] age, 46.28 (37.44,54.8); 516 [77.4%] female) in the symptomatic disease analysis, and 532 participants (median [IQR] age, 48 [39-56] years; 403 [75.8%] female) in the infectivity analysis. Lower odds of infection were observed for each 10-fold increase in preinfection IgG (odds ratio [OR], 0.71; 95% CI, 0.56-0.90) and for each 2-fold increase in neutralizing antibody titers (OR, 0.89; 95% CI, 0.83-0.95). The odds of substantial symptomatic disease were reduced for each 10-fold increase in IgG levels (OR, 0.48; 95% CI, 0.29-0.78) and for each 2-fold increase in neutralizing antibodies levels (OR, 0.86; 95% CI, 0.76-0.96). Infectivity, assessed by mean cycle threshold value, was not significantly decreased with increasing IgG or neutralizing antibodies titers.Conclusions and RelevanceIn this cohort study of vaccinated health care workers, IgG and neutralizing antibody titer levels were associated with protection against infection with the Omicron variant and against symptomatic disease.

Abstract

The biodiversity and climate crises are critical challenges of this century. Wildflower meadows in urban areas could provide important nature‐based solutions, addressing the biodiversity and climate crises jointly and benefitting society in the process. King's College Cambridge (England, UK) established a wildflower meadow over a portion of its iconic Back Lawn in 2019, replacing a fine lawn first laid in 1772.

We used biodiversity surveys, Wilcoxon signed rank and ANOVA models to compare species richness, abundance and composition of plants, spiders, bugs, bats and nematodes supported by the meadow, and remaining lawn, over 3 years. We estimated the climate change impact of meadow vs lawn from maintenance emissions, soil carbon sequestration and reflectance effect. We surveyed members of the university to quantify the societal benefits of, and attitudes towards, increased meadow planting on the collegiate university estate.

In spite of its small size (0.36 ha), the meadow supported approximately three times more plant species, three times more spider and bug species and individuals, and bats were recorded three times more often over the meadow than the remaining lawn. Terrestrial invertebrate biomass was 25 times higher in the meadow compared with the lawn. Fourteen species with conservation designations were recorded on the meadow (six for lawn), alongside meadow specialist species.

Reduced maintenance and fertilising associated with meadow reduced emissions by an estimated 1.36 Mg CO2‐e per hectare per year compared with lawn. Relative reflectance increased by 25%–34% for meadow relative to lawn. Soil carbon stocks did not differ between meadow and lawn.

Respondents thought meadows provided greater aesthetic, educational and mental wellbeing services than lawns. In open responses, lawns were associated with undesirable elitism and social exclusion (most colleges in Cambridge restrict lawn access to senior members of college), and respondents proved overwhelmingly in favour of meadow planting in place of lawn on the collegiate university estate.

This study demonstrates the substantial benefits of small urban meadows for local biodiversity, cultural ecosystem services and climate change mitigation, supplied at lower cost than maintaining conventional lawn.

ObjectiveSynovitis and tenosynovitis are present in juvenile idiopathic arthritis (JIA), both as joint pain and/or inflammation, making them difficult to detect on physical examination. Although ultrasonography (US) allows for discrimination of the 2 entities, only definitions and scoring of synovitis in children have been established. This study was undertaken to produce consensus‐based US definitions of tenosynovitis in JIA.MethodsA systematic literature search was performed. Selection criteria included studies focused on US definition and scoring systems for tenosynovitis in children, as well as US metric properties. Through a 2‐step Delphi process, a panel of international US experts developed definitions for tenosynovitis components (step 1) and validated them by testing their applicability on US images of tenosynovitis in several age groups (step 2). A 5‐point Likert scale was used to rate the level of agreement.ResultsA total of 14 studies were identified. Most used the US definitions developed for adults to define tenosynovitis in children. Construct validity was reported in 86% of articles using physical examination as a comparator. Few studies reported US reliability and responsiveness in JIA. In step 1, experts reached a strong group agreement (>86%) by applying adult definitions in children after one round. After 4 rounds of step 2, the final definitions were validated on all tendons and at all locations, except for biceps tenosynovitis in children <4 years old.ConclusionThe study shows that the definition of tenosynovitis used in adults is applicable to children with minimal modifications agreed upon through a Delphi process. Further studies are required to confirm our results.

AbstractThe metal‐insulator phase transitions in V2O3 are considered archetypal manifestations of Mott physics. Despite decades of research, the effects of doping, pressure, and anisotropic strains on the transitions are still debated. To understand how these parameters control the transitions, anisotropically strained pure V2O3 films are explored with nearly the same contraction along the c‐axis, but different degrees of ab‐plane expansion. With small ab‐plane expansion, the films behave similar to bulk V2O3 under hydrostatic pressure. However, with large ab‐plane expansion, the films are driven into the “negative pressure” regime, similar to that of Cr‐doped V2O3, exhibiting clear coexistence of paramagnetic insulator and paramagnetic metal phases between 180–500 K. This shows that c‐axis contraction alone, or an increase in c/a ratio is insufficient for inducing “negative pressure” effects. Actually, c‐axis contraction alone destabilizes the two insulating phases of V2O3, whereas a‐axis expansion tends to stabilize them. The effects of strain are modeled using density functional theory providing good agreement with experimental results. The findings show that chemical pressure alone cannot account for the phase diagram of (V1−xCrx)2O3. This work enables to manipulate a Mott transition above room temperature, thereby expanding the opportunities for applications of V2O3 in novel electronics.

AbstractThe electrocatalytic CO2 reduction reaction (CO2RR) has been considered a promising route toward carbon neutrality and renewable energy conversion. At present, most bismuth (Bi) based electrocatalysts are adopted to reduce CO2 to formate (HCOOH). However, the mechanism of different Bi nanostructures on the electrocatalytic performance requires more detailed exposition. Herein, a combined chemical replacement and electrochemical reduction process is reported to realize in situ morphology reconstruction from Bi@Bi2O3 nanodendrites (Bi@Bi2O3‐NDs) to Bi nanoflowers (Bi‐NFs). The Bi@Bi2O3‐NDs are proven to undergo a two‐step transformation process to form Bi‐NFs, aided by Bi2O2CO3 as the intermediate in KHCO3 solution. Extensive surface reconstruction of Bi@Bi2O3‐NDs renders the realization of tailored Bi‐NFs electrocatalyst that maximize the number of exposed active sites and active component (Bi0), which is conducive to the adsorption and activation of CO2 and accelerated electron transfer process. The as‐prepared Bi‐NFs exhibit a Faradaic efficiency (FEformate) of 92.3% at −0.9 V versus RHE and a high partial current density of 28.5 mA cm−2 at −1.05 V versus RHE for the electroreduction of CO2 to HCOOH. Moreover, the reaction mechanism is comprehensively investigated by in situ Raman analysis, which confirms that *OCHO is a key intermediate for the formation of HCOOH.

AbstractLithium–sulfur (Li–S) batteries are famous for their high energy density and low cost, but prevented by sluggish redox kinetics of sulfur species due to depressive Li ion diffusion kinetics, especially under low‐temperature environment. Herein, a combined strategy of electrocatalysis and pore sieving effect is put forward to dissociate the Li+ solvation structure to stimulate the free Li+ diffusion, further improving sulfur redox reaction kinetics. As a protocol, an electrocatalytic porous diffusion‐boosted nitrogen‐doped carbon‐grafted‐CoP nanosheet is designed via forming the NCoP active structure to release more free Li+ to react with sulfur species, as fully investigated by electrochemical tests, theoretical simulations and in situ/ex situ characterizations. As a result, the cells with diffusion booster achieve desirable lifespan of 800 cycles at 2 C and excellent rate capability (775 mAh g−1 at 3 C). Impressively, in a condition of high mass loading or low‐temperature environment, the cell with 5.7 mg cm−2 stabilizes an areal capacity of 3.2 mAh cm−2 and the charming capacity of 647 mAh g−1 is obtained under 0 °C after 80 cycles, demonstrating a promising route of providing more free Li ions toward practical high‐energy Li–S batteries.
From Monomer Sequence to Charge Mobility in Semiconductor Polymers via Model Reduction
Authors: Prodhan Suryoday , Manurung Rex , Troisi Alessandro 
Published: May 2023

AbstractA model reduction scheme for polymer semiconductors is presented that can be utilized to compute intra‐chain charge‐carrier mobility from the monomer sequence. The reduced model can be used in conjunction with any quantum dynamics approach, but it is explored here assuming that transport takes place through incoherent hopping events between states of different degrees of delocalization. The procedure is illustrated by considering 28 realistic polymers for which a quantitative correlation is established between charge localization characteristics and charge mobility. The data set helps in establishing plausible ranges for all the microscopic parameters of the model and it can therefore be used to determine the maximum plausible improvement in mobility. The reduced model is also used to provide some insight on the observation that the highest mobility polymers do not have very broad valence bands: there is indeed a range of the inter‐monomer coupling for which this parameter has little effect on the mobility.

AbstractHigh‐energy electrolytic Zn//MnO2batteries show potential for grid‐scale energy storage, but the severe hydrogen evolution corrosion (HEC) caused by acidic electrolytes results in subdued durability. Here, an all‐around protection strategy is reported for achieving stable Zn metal anodes. First, a proton‐resistant Pb‐containing (Pb and Pb(OH)2) interface is constructed on a Zn anode (denoted as Zn@Pb), which in situ forms PbSO4during H2SO4corrosion and protects the Zn substrate from HEC. Second, to improve the plating/stripping reversibility of Zn@Pb, Pb(CH3COO)2an additive (denoted as Zn@Pb‐Ad) is introduced, which triggers PbSO4precipitation and releases trace Pb2+that can dynamically deposit a Pb layer on the Zn plating layer to suppress HEC. The superior HEC resistance stems from the low affinity of PbSO4and Pb for H+, as well as strong bonding between Pb–Zn or Pb–Pb, which increase the hydrogen evolution reaction overpotential and the H+corrosion energy barrier. Consequently, the Zn@Pb‐Ad//MnO2battery runs stably for 630 and 795 h in 0.2 and 0.1 mH2SO4electrolytes, respectively, which are >40 times better than that of bare Zn. The as‐prepared A h‐level battery achieves a one‐month calendar life, opening the door to the next generation of high‐durable grid‐scale Zn batteries.

AbstractCatalysts with designable intelligent nanostructure may potentially drive the changes in chemical reaction techniques. Herein, a multi‐function integrating nanocatalyst, Pt‐containing magnetic yolk‐shell carbonaceous structure, having catalysis function, microenvironment heating, thermal insulation, and elevated pressure into a whole is designed, which induces selective hydrogenation within heating‐constrained nanoreactors surrounded by ambient environment. As a demonstration, carbonyl of α, β‐unsaturated aldehydes/ketones are selectively hydrogenated to unsaturated alcohols with a >98% selectivity at a nearly complete conversion under mild conditions of 40 °C and 3 bar instead of harsh requirements of 120 °C and 30 bar. It is creatively demonstrated that the locally increased temperature and endogenous pressure (estimated as ≈120 °C, 9.7 bar) in the nano‐sized space greatly facilitate the reaction kinetics under an alternating magnetic field. The outward‐diffused products to the “cool environment” remain thermodynamically stable, avoiding the over‐hydrogenation that often occurs under constantly heated conditions of 120 °C. Regulation of the electronic state of Pt by sulfur doping of carbon allows selective chemical adsorption of the CO group and consequently leads to selective hydrogenation. It is expected that such a multi‐function integrated catalyst provides an ideal platform for precisely operating a variety of organic liquid‐phase transformations under mild reaction conditions.

AbstractThere has been enormous interest in technologies that generate electricity from ambient energy such as solar, thermal, and mechanical energy, due to their potential for providing sustainable solutions to the energy crisis. One driving force behind the search for new energy‐harvesting technologies is the desire to power sensor networks and portable devices without batteries, such as self‐powered wearable electronics, human health monitoring systems, and implantable wireless sensors. Various energy harvesting technologies have been demonstrated in recent years. Among them, electrochemical, hydroelectric, triboelectric, piezoelectric, and thermoelectric nanogenerators have been extensively studied because of their special physical properties, ease of application, and sometimes high obtainable efficiency. Multifunctional carbon nanotubes (CNTs) have attracted much interest in energy harvesting because of their exceptionally high gravimetric power outputs and recently obtained high energy conversion efficiencies. Further development of this field, however, still requires an in‐depth understanding of harvesting mechanisms and boosting of the electrical outputs for wider applications. Here, various CNT‐based energy harvesting technologies are comprehensively reviewed, focusing on working principles, typical examples, and future improvements. The last section discusses the existing challenges and future directions of CNT‐based energy harvesters.
Hydraulically Amplified Electrostatic Taxels (HAXELs) for Full Body Haptics
Authors: Leroy Edouard , Shea Herbert 
Published: May 2023

AbstractThe ability to mechanically stimulate touch receptors over the entire body is a key feature for fully immersive and highly realistic virtual reality experience. Haptic stickers, flexible arrays of HAXELs (hydraulically amplified TAXels), that enable cutaneous haptics over nearly all parts of the body, are reported. HAXELs are zipping electrostatic actuators that combine stretchable elastomers and high permittivity flexible films to generate both high strains and high forces, from DC to 200 Hz. A fabrication process that enables scaling HAXELs from 2 to 15 mm in diameter is presented, allowing to tailor the actuators to different body parts and to wearables such as wrist‐watches. The different sizes of HAXELs generate blocked forces from 100 to 800 mN, with DC displacements from 100 to 850 µm, well above sensation thresholds. Haptics tests of Haptic Stickers, 5 × 5 arrays of 10 mm diameter devices, on palms, back of the hand, neck, arm, and back of a dozen volunteers, are done with users reporting high pattern recognition success on many body locations. The Haptic Stickers uniquely offer a thin and lightweight form‐factor, which does not limit the freedom of motion of the user, compatible with untethered scenarios.
