A stultitia na contemporaneidade e a importância da leitura e da escrita em escolas e universidades
Resumo: Este artigo é um ensaio teórico que parte de investigações da antiguidade greco-romana por Foucault, principalmente de seus estudos sobre Sêneca, para recuperar o conceito de stultitia e com ele pensarmos o nosso tempo. A partir do diagnóstico de um presente da superaceleração e do superdesempenho, em que se compete consigo mesmo e a atenção está dispersa, a passividade está em justamente não conseguirmos parar para olhar para nós mesmos e para os demais. Para essa agitação contemporânea, afirmamos a importância de escolas e universidades, bem como da figura do mestre, que, por meio da leitura e da escrita, poderá convidar o outro a cuidar de si mesmo e dos demais.

Stultitia in contemporaneity and the importance of reading and writing in schools and universities
Abstract: This paper is a theoretical essay grounded on Foucault’s investigations of Greek-Roman Antiquity, particularly his studies on Seneca, in order to recover the concept of stultitia and use it to think about our times. From the diagnosis of a present of super-acceleration and super-performance, in which one competes with oneself and attention is dispersed, passivity is precisely in not being possible to stop and look at the others and ourselves. For this contemporary unrest, we point out the importance of schools and universities, as well as the figure of the master, who, by means of reading and writing, may invite the other to look after the others and oneself.

Study on the changes in vegetation structural coverage and its response mechanism to hydrology
Authors: Wu Dan , Liu QiXing , Xia RunLiang , Li Tao 
Published: February 2022

Abstract
Vegetation is an important factor that affects the hydrological process of a watershed. In recent years, the vegetation in the hilly and gully regions of the Loess Plateau has undergone significant changes, which have greatly changed the relationship between rainfall and runoff and sediment in the region. A single vegetation cover index cannot represent the important impact of vegetation grade on the effectiveness of soil and water conservation. It is of great scientific significance to deeply study the influence of the vegetation structure change mechanism in the hilly and gully area on the hydrological process of the watershed. In this article, a typical watershed in the loess hilly and gully area is used as the research object, and the method of combining field sampling experiment and remote sensing inversion is used to establish a vegetation index remote sensing model reflecting the vegetation canopy cover and litter. The impact of changes in vegetation structure on hydrological processes is quantitatively assessed. The results show that the more annual precipitation in the basin, the more sensitive the runoff coefficient is to changes in structural vegetation index. The greater the rainfall intensity, the weaker the sensitivity of the sediment yield coefficient to changes in structural vegetation index. The use of remote sensing data to retrieve the underlying surface vegetation still has the problem of the scale effect. It is necessary to further use remote sensing data with a higher spectral resolution to carry out field observations at different scales to improve the applicability of this method in a wider range of watersheds.

Published: February 2022

Abstract
The ternary Al –Ca –Mg phase equlibria were investigated using X-ray diffraction methods, metallography, scanning electron microscopy with energy- and wave-length-dispersive X-ray microanalysis, and differential thermal analysis. The phase diagram was determined in the complete composition range. Large ternary solubilities were found for the binary phases CaMg2, Al2Ca and Al3Ca8. Microstructures of samples with compositions near the ternary monovariant eutectic L → CaMg2 + Al2Ca show remarkable rod-like crystals that are identified as intergrowth between CaMg2 and Al2Ca. A consistent thermodynamic model was developed using the Calphad method incorporating all experimental data. It was used to calculate all pertinent phase equilibria of the Al –Ca –Mg system.
Residual stresses in forged IN718 turbine discs

Published: February 2022

AbstractResidual stresses play an important role in the production of forged components like turbine discs. Variations in the processing parameters can lead to different residual stress states, which complicate subsequent processing steps, e. g. turning to the final shape. Therefore, a deeper understanding of the residual stress evolution during thermo-mechanical processing and the resulting distortions during machining is essential in order to optimize the manufacturing process with respect to cost efficiency and quality of the product. Consequently, the development of residual stresses in a forged turbine disc made of nickel-based superalloy IN718 was simulated using a finite element (FE) model. The experimental verification of the model was done by independently performed neutron strain scanning. For the studied forged and subsequently water-quenched disc the obtained residual stresses agree well with the stresses predicted by the used FE.

Abstract
The GaAs-based material system is well-known for hosting InAs quantum dots (QDs) with outstanding optical properties, typically emitting at a wavelength of around 900 nm. The insertion of a metamorphic buffer (MMB) can shift this emission to the technologically attractive telecom C-band range centered at 1550 nm. However, the thickness of common MMB designs (>1 μm) limits their compatibility with most photonic resonator types. Here, we report on the metal–organic vapor-phase epitaxy (MOVPE) growth of a novel InGaAs MMB with a nonlinear indium content grading profile designed to maximize plastic relaxation within minimal layer thickness. This allows us to achieve the necessary transition of the lattice constant and to provide a smooth surface for QD growth within 180 nm. Single-photon emission at 1550 nm from InAs QDs deposited on top of this thin-film MMB is demonstrated. The strength of the new design is proven by integrating it into a bullseye cavity via nano-structuring techniques. The presented advances in the epitaxial growth of QD/MMB structures form the basis for the fabrication of high-quality telecom nonclassical light sources as a key component of photonic quantum technologies.
A generalized method for calculating plasmoelectric potential in non-Mie-resonant plasmonic systems

Published: February 2022

Abstract
Since its first observation in 2014, plasmoelectric potential (PEP) has drawn a great deal of research interest in all-metal optoelectronics and photochemistry. As an optical thermodynamic phenomenon induced by the electron number dependent equilibrium temperature in plasmonic nanostructures, the early theoretical model developed for calculating PEP is only applicable to Mie-resonant nanostructures, such as a gold nanosphere on a conductive indium tin oxide (ITO) substrate, where the transfer efficiency of hot electrons from gold to ITO can be analytically determined. Without the presence of the substrate, the temperature increase on the gold nanosphere induced by plasmonic absorption was calculated on the basis of thermal radiation in vacuum, which probably over-estimates the actual temperature increase in comparison to realistic experimental conditions. Here, we propose an equilibrium-thermodynamics computational method to quantify the actual efficiency of plasmon-induced electron transfer between a non-Mie-resonant metallic nanostructure and a conductive substrate and hence determine the resultant plasmoelectric potential. With a less than 2.5% relative error in predicting the steady-state temperature of a Mie-resonant nanoparticle in vacuum, and a more strict evaluation of the plasmonic local heating induced temperature increase in a single plasmonic nanostructure or an array of such structures under continuous-wave illumination (CWI), our generalized method provides a robust and accurate approach for quantifying PEP in various plasmonic-particle (array)-on-film nanocavities.

Abstract
Interaction between light and magnetism in magneto-optical (MO) nanophotonic devices has been actively studied in the past few years. The recent development of MO all-dielectric resonators and metasurfaces has led to the emergence of various novel MO phenomena that were not observed in their bulk counterparts. For example, a large s-polarized transverse MO Kerr effect can be observed at magnetic resonance wavelength, which cannot exist in the bare MO films. We review recent developments in nanophotonic devices based on MO materials and focus on different modes and related MO effects in nanophotonic structures with emphasis on recently discovered new MO phenomena in magnetoplasmonics and all-dielectric nanostructures, such as dark mode, all-dielectric Mie resonance and waveguide mode. Further, we discuss the potential applications of these nanostructures for biological/chemical sensing, magnetic field sensing, and magnetic field-controlled active and nonreciprocal metasurfaces.
Automation Processes in the Port Industry and Union Strategies: The Case of Antwerp
Authors: Bottalico Andrea 
Published: February 2022

Abstract
Automation represents a sensitive issue in the debate between social actors of the port-maritime industry. Automation produced a contraction of the number of dockworkers since the 1960s. However, the idea that technological innovation will produce the disappearance of work is not sustained by empirical evidence. For this reason, trade unions have been particularly watchful. Despite the discourses about robotization carried out by supply chain operators, the paradigm of the post-COVID logistics chain is still based upon the human labor cost. During the pandemic there has been a transformation in working conditions not in terms of replacing people with robots, but rather of the robotization of workers to obtain the maximum productive exploitation at the minimum wage allowed. The purpose of this article is to provide an analysis of labor relations and workers organizing in light of the automation processes in the European port of Antwerp. The article focuses on how working conditions and jobs are potentially impacted by automation in ports, and on how workers disruptive strategies are resisting to these dynamics. The following questions have been answered: How do trade unions and dockworkers respond to automation? What are the strategies implemented in the bargaining processes?

AbstractAssessment of human epidermal growth factor receptor-2 (HER2) tumor marker status is an impressive factor in screening, diagnosing and monitoring breast cancer (BC). The electrochemical biosensor is a revolutionary method in cancer diagnosis, which is used in this research to detect HER2+circulating tumor cells. The electrochemical activity, size, shape, and morphology of the synthesized nanomaterials were analyzed. The hybrid nanocomposite established by the coupling of reduced graphene oxide nanosheets (rGONs) and rhodium nanoparticles (Rh-NPs) on the surface of graphite electrode resulted in improved surface area, electrochemical activity, and biocompatibility. The graphite electrode-based aptasensor (g-aptasensor) demonstrated exceptional performance against HER2-overexpressed SKBR3 cancer cells, with a linear dynamic range of 5.0 to 10.0 × 104 cells/mL, an analytical limit of detection (LOD) as low as 1.0 cell/mL, and a limit of quantification (LOQ) of 3.0 cells/mL. The G-rich DNA aptamers can fold into an intermolecular G-quadruplex, which specifically bind to the target molecule. Consequently, the advantages of this highly efficient nanocomposite platform include broad dynamic range, high specificity, selectivity, stability, reproducibility, and low cost. These characteristics indicate that the fabricated nanobiosensor has a high potential for use in detecting and monitoring HER2 level for the care of BC patients and clinical diagnosis.

Authors: Hu Xuechen , Gao Xingjian , Xu Wenzhen , Takai Jiro 
Published: February 2022

Abstract

Purpose
This study examined the psychological and social factors that affect the performance of preventive behaviors toward COVID-19, by testing a model based on the theory of planned behavior (TPB). Our model featured media exposure and social networking site (SNS) involvement, and we tested it in two highly contrasted cultures regarding COVID-19 attitudes: U.S. and Japan.

Method
An online survey collected 300 samples for each culture. Participation was voluntary, for monetary compensation through crowd-sourcing platforms.

Findings
Overall, the results showed a good fit of our TPB model in each culture. Media exposure was a major predictor of risk perception in both cultures, while engagement in SNS predicted intention to perform preventive behavior for the Japanese only, and personal hygiene was found to be a significant predictor of protective behavior once again only for the Japanese.

Implications and Value
While there were differences in the variables affecting preventive behaviors, overall, our proposed model proved to be robust across both cultures. Implications were made on differences between tight and loose cultures, as represented by Japan and the US, regarding COVID-19 preventive attitudes.

Abstract
The purpose of the current study is to understand how the COVID-19 pandemic has affected eating behavior and directed toward organic food and bioproducts consumption in the North African region especially Morocco, Algeria, and Tunisia as well as identify the variables that may affect the eating behavior of these population. Data were collected using an anonymous online survey on 1,244 respondents from Morocco, Algeria, and Tunisia. The results showed that the confinement did influence the consumption of healthy food to enhance people’s immune system so as to prevent infection by the COVID-19, and other diseases. Moreover, academic level, gender, and country of residence were diversely correlated with the eating behavior during COVID-19 confinement. The understanding of people’s eating behavior will help the public health to reshape future policies toward organic and bio-based food production; moreover, some further nutritional recommendations could be concluded to maintain a global better health status and improve body defence mechanism.
Confessional Discourses, Radicalizing Traditions: On John Caputo and the Theological Turn
Authors: Sands Justin 
Published: February 2022

AbstractThis article explores the theological turn through the work of John Caputo, who famously transitioned from a philosopher of religion to a “weak theologian,” and later as a “radical theologian.” In so doing it argues that Caputo’s work as a radical theologian is an attempt at a practical performance of religion without religion: he inhabits the discourse of theology while radicalizing the tradition against itself. This article will show the value of this theological approach and how Caputo needs to directly inhabit this discourse as a theologian – confessing to be a theologian, becoming one of “their own” – to change theology’s trajectory. This trajectorial shift is felt both inside the academy and within the church itself. Caputo’s transformation from a philosopher to a theologian is a move from a (philosophical) description to a (theological) prescription. It is a transition from theory to praxis, and he could not do this without inhabiting that praxis’ context and its discourses. In doing so, and perhaps unintentionally, Caputo surprisingly respects critics like Dominique Janicaud, whose strident critique against the theological turn was at its apotheosis during Caputo’s transition: Caputo never ventures into crypto-theology nor does he sneak in prescription under the guise of a “phenomenology,” as many philosophers of religion are wont to do. Rather, he sees that one needs to embody the discourse to change it, which, ironically, is a position that would gain the approval of both Dominique Janicaud and traditional theology.

Published: February 2022

Abstract
With the rapid development of urbanization and industrialization, environmental pollution has become more severe. Volatile organic compounds (VOCs) could be originated from the following sources: domestic, mobile and industrial sources. As important air pollutants, VOCs could cause serious harm to the environment and human health. Therefore, removing VOCs has become a priority research direction of ecological issues. Among the many elimination methods, catalytic oxidation approaches are among the most effective and economical methods which can transform VOCs into CO2 and H2O. MnOx catalysts are among the most active catalysts, which can be further modified by different cations such as Cu2+, Co2+, Cr3+, Ni2+ and Ce4+ to form mixed oxides to improve the catalytic oxidation of VOCs activity. Moreover, MnOx can be loaded on the carrier, improving the redox and oxygen storage capacity and improving its stability and activity. This review explores the structure, preparation and oxidation state of Mn-based catalysts.

Abstract
Huang, Z-H, Ma, CZ-H, Wang, L-K, Wang, X-Y, Fu, S-N, and Zheng, Y-P. Real-time visual biofeedback via wearable ultrasound imaging can enhance the muscle contraction training outcome of young adults. J Strength Cond Res 36(4): 941–947, 2022—Real-time ultrasound imaging (RUSI) can serve as visual biofeedback to train deep muscle contraction in clinical rehabilitative settings. However, its effectiveness in resistance training in sports/fitness fields remains unexplored. This article introduced a newly developed wearable RUSI system that provided visual biofeedback of muscle thickening and movement and reported its effectiveness in improving the training outcomes of muscle thickness change (%) during dynamic contraction. Twenty-five healthy young men participated and performed pec fly exercise both with and without RUSI biofeedback. Statistical analysis was conducted to examine the reliability of the measurements and the immediate effects of (a) RUSI biofeedback of muscle contraction and (b) training intensity (50 vs. 80% of 1-repetition maximum [1RM]) on the pectoralis major (PMaj) thickness change measured by ultrasound images. In addition to significantly high inter-contraction reliability (ICC3,1 > 0.97), we observed significantly increased PMaj thickness change for both training intensities upon receiving biofeedback in subjects, compared with without biofeedback (p < 0.001). We also observed significantly larger PMaj thickness change at 80% of 1RM compared with 50% of 1RM (p = 0.023). The provision of visual biofeedback using RUSI significantly enlarged the magnitude of PMaj thickness change during pec fly exercises, potentially indicating that RUSI biofeedback could improve the ability of targeted muscle contraction of PMaj in healthy young adults. To our knowledge, this study has pioneered in applying RUSI as a form of biofeedback during weight training and observed positive effectiveness. Future iterations of the technique will benefit more subject groups, such as athletes and patients with neuromuscular disorders.
