Seizing this COVID moment: What can Food Justice learn from Disability Justice?

It is now a shameful truism that COVID-19 functioned as a big reveal, exposing, and amplifying the structural inequalities Canadian society is built upon. We are now a year and a half into the global pandemic. I am writing from Toronto, where “hot spots” (neighbourhoods with high infection rates) is code for racial and economic inequality (Wallace 2021) and public health guidelines have rendered low income “essential workers” disposable, amidst ballooning food insecurity rates, especially in low-income racialized communities (Toronto Foundation 2020; CBC News 2020). We are all in the same storm but in very different boats, as the new saying goes. I want to suggest that this moment, as Canadians are poised to step out of lockdown and return to ‘normal’, is a particularly useful one for Food Studies to consider what we could learn from Disability Justice movements in order to address a glaring hole in our collective scholarship and analysis.
Emotions as a lasting leadership learning in high-potential female students

Women's underrepresentation in leadership positions is a well-known problem. The lack of self-confidence and training in leadership is highlighted in the literature as the two main barriers to women seeking managerial positions. Educational organizations have to provide leadership skills development and gain-oriented personal resources through women's leadership programs. Research demonstrates that emotions improve the learning process in educational activities. Nevertheless, to our knowledge, there has been little feminist research focused on how emotions modulate the learning process in educational leadership programs and how they promote students’ personal change, which needs to last in time. To fill this gap, the objective of this study is to present an evaluation of the impact of emotions on a leadership program for female undergraduates, using a multi-source program assessment based on triangulation. The study analyzes the students' emotions during and after the university Women's Leadership Program (WLP), exploring their learning processes in the acquisition of formal leadership skills, personal resources, and personal inner transformation as a fusion of their emotions. The Achievement Emotions Questionnaire (AEQ) scale was applied including 9 items (α= 0.72). Bivariate analyses were conducted using an analysis of variance (ANOVA) and exploratory factor analysis. Additionally, focus groups were carried out at the end of the course, two weeks after, to allow time for reflection by the participants. The analysis was carried out as a conventional content analysis (inductive). The results of an online survey and focus groups with the students and the perceptions of the lecturers suggest that emotions contributed to fostering the learning of leadership skills and triggering deep inner personal development. The findings indicate that i) positive and negative valence contributes to the appraisal process, helping them to be self-reflective about their personal leadership qualities, ii) reinforcing their own shortcomings and improving self-skills such as confidence, building leadership fluidly. In addition, the emotional state of the trainers who accompanied the students during the sessions of the program was highly significant, becoming emotional triggers. Furthermore, trainers also become role models. Practical implications for the future are provided for the educational institutions and business managers to improve women leadership programs
Two-Way Communication Digital Power Controllers for Wireless Retinal Prosthesis Systems

Power-efficient digital controllers are proposed for wireless retinal prosthetic systems. Power management plays an important role in reducing the power consumption and avoiding malfunctions in implantable medical devices. In the case of implantable devices with only one-way communication, the received power level is uncertain because there is no feedback on the power status. Accordingly, system breakdown due to inefficient power management should be avoided to prevent harm to patients. In this study, digital power controllers were developed for achieving two-way communication. Three controllers—a forward and back telemetry control unit, a power control unit, and a preamble control unit—operated simultaneously to control the class-E amplifier input power, provided command data to stimulators, monitored the power levels of the implanted devices, and generated back telemetry data. For performance verification, we implemented a digital power control system using a field-programmable gate array and then demonstrated it by employing a wireless telemetry system.

The campaign against COVID-19 in Nigeria: exploring church leaders’ role perception and action

ABSTRACT Due to the constructive roles religious leaders played during previous pandemics, the World Health Organization (WHO) and other organizations have outlined the roles expected of religious leaders in the current campaign against COVID-19. However, during previous pandemics, some religious leaders also undermined public-health measures. Thus, it is important to understand what religious leaders think of the expectations of health organizations, as well as their responses to the pandemic. This study explored church leaders’ role perception and action towards COVID-19 in Nigeria. Data were collected through semi-structured interviews with eighteen church leaders from Catholic, Anglican, and Pentecostal churches. Using a thematic analysis method, the study found that while all the participants agreed to have roles in the campaign against COVID-19, interpretations of these roles and the corresponding actions differed between those who promote public-health measures and those who undermine these measures. Implications of findings for policy and research are discussed.
Quadrature Filter Approximation for Reconstructing the Complex Envelope of a Bandpass Signal Sampled Directly With a Two-Channel TIADC

A general and flexible technique is proposed for sampling the complex envelope of a bandpass signal by using a nonuniformly interleaved two-channel analog-to-digital converter (TIADC). The signal is sampled directly without any demodulation operation, but the two sampling channels are not uniformly interleaved, since some TIADC timing offsets are rendered forbidden. The proposed complex envelope sampling scheme requires the implementation of two digital FIR filters and a discrete-time modulator. Quadrature sampling, a special case that assumes certain parameter relations, is investigated as an approximation technique. Computer simulations are presented and illustrate a −57dB mean-square error (MSE) can be achieved via quadrature approximation for sufficiently large filter orders.

Neural network algorithm is used for comprehensive analysis to realize multivariate analysis and objective evaluation of all data of dynamic motion process and accurate analysis and evaluation according to different data characteristics of different types of motion data. The results show that the data mining model based on discrete dynamic modeling technology and wearable sensor technology has the advantages of high feasibility, high intelligence, and wide application range.
Occurrence and Genetic Characterization of Grapevine Pinot Gris Virus in Russia

Grapevine Pinot gris virus (GPGV) is a widespread grapevine pathogen associated with symptoms of leaf mottling and deformation. In order to study the distribution and genetic diversity of GPGV in Russia, we tested 1347 grapevine samples from 3 regions of Russia–the Krasnodar Krai, Stavropol Krai, and Republic of Crimea—using duplex real-time RT-PCR. GPGV was detected in 993 grapevines, both symptomatic and asymptomatic. In 119 isolates, we sequenced complete movement protein (MP) and coat protein (CP) genes of the GPGV genome. The percentage of identity of the obtained nucleotide MP/CP sequences with the closest isolates from the GenBank was 97.75–99.56%. A phylogenetic analysis showed that these Russian GPGV isolates are mainly grouped with previously described representative asymptomatic isolates. New post-translational modifications of the MP and CP at the positions of polymorphisms in the genomes of Russian isolates were predicted. The present work is the first study on the distribution and genetic diversity of GPGV in Russia.
P2X7 Receptor Augments LPS-Induced Nitrosative Stress by Regulating Nrf2 and GSH Levels in the Mouse Hippocampus

P2X7 receptor (P2X7R) regulates inducible nitric oxide synthase (iNOS) expression/activity in response to various harmful insults. Since P2X7R deletion paradoxically decreases the basal glutathione (GSH) level in the mouse hippocampus, it is likely that P2X7R may increase the demand for GSH for the maintenance of the intracellular redox state or affect other antioxidant defense systems. Therefore, the present study was designed to elucidate whether P2X7R affects nuclear factor-erythroid 2-related factor 2 (Nrf2) activity/expression and GSH synthesis under nitrosative stress in response to lipopolysaccharide (LPS)-induced neuroinflammation. In the present study, P2X7R deletion attenuated iNOS upregulation and Nrf2 degradation induced by LPS. Compatible with iNOS induction, P2X7R deletion decreased S-nitrosylated (SNO)-cysteine production under physiological and post-LPS treated conditions. P2X7R deletion also ameliorated the decreases in GSH, glutathione synthetase, GS and ASCT2 levels concomitant with the reduced S-nitrosylations of GS and ASCT2 following LPS treatment. Furthermore, LPS upregulated cystine:glutamate transporter (xCT) and glutaminase in P2X7R+/+ mice, which were abrogated by P2X7R deletion. LPS did not affect GCLC level in both P2X7R+/+ and P2X7R−/− mice. Therefore, our findings indicate that P2X7R may augment LPS-induced neuroinflammation by leading to Nrf2 degradation, aberrant glutamate-glutamine cycle and impaired cystine/cysteine uptake, which would inhibit GSH biosynthesis. Therefore, we suggest that the targeting of P2X7R, which would exert nitrosative stress with iNOS in a positive feedback manner, may be one of the important therapeutic strategies of nitrosative stress under pathophysiological conditions.
Designing hard, low-refractive-index lossy materials for super wear-resistant absorbers

Super wear-resistant absorbers are important for next-generation high-stability optical splitters. However, traditional absorbers cannot obtain ideal wear resistance because of the limitation of hardness. We show that solid solutions of transition metal carbides are new hard, low-refractive-index lossy materials (HLLM). Super wear-resistant absorbers were obtained by constructing HLLM-based optical cavities. As a proof-of-concept, the absorptance of our fabricated Ti0.93W0. 07C-based optical cavity was 95.6% in 400–800 nm wavelength range. In addition, its wear resistance was 23.3 times greater than that of traditional absorbers. Through the experiments and theoretical calculations, we proposed the design principles of HLLM and presented the materials map. IMPACT STATEMENT We obtained the super wear-resistant absorbers for the first time through designing hard, low-refractive-index lossy materials, and constructing an optical cavity with the lossy materials as the top layer.
Adaptive Short-Temporal Induced Aware Fusion Network for Predicting Attention Regions Like a Driver

Driver attention prediction can solve the problem of ‘Where should the driver pay attention? ’, Most previous methods are designed to predict regional attention with redundant regions. Furthermore, popular spatial-temporal feature extraction networks such as ConvLSTM and 3D-CNN are difficult to achieve real-time. To overcome these difficulties, we propose an Adaptive Short-temporal Induced Aware Fusion Network (ASIAF-Net) for region-level and object-level driver attention prediction.1 In ASIAF-Net, we design an Attention Related Spatial Feature Encoder (AF-Encoder) and an Induced Aware Fusion Network (IAF-Net) as the main network; with an Association Analysis Cell (AAC), the AF-Encoder makes it possible to effectively capture the relationship information of different objects. Considering most vital visual cues from moving objects, we propose a Self-adaptive Short-temporal Feature Extraction Module (SSFE-Module) to obtain inter-frame motion features. In IAF-Net, a Multi-scale Driver Attention Region Prediction Branch is designed to predict the regional attention, and an Object Saliency Estimation Branch is proposed to fuse the perception results and the regional attention map to estimate the object-level attention. Experiments show that the proposed ASIAF-Net can predict driver’s attention on regions and objects more robustly and precisely than state-of-the-art methods on three datasets, and that it achieves real-time on our ADAS platform.
Correlations between Functional Movement Screening (FMS) Results and the Range of Motion of Lower Limb Joints Young Middle Distance Runners

Background : The relationship between range of motion (ROM) in lower limb joints and Functional movement screen still not clear. The aim of this study was therefore to investigate the correlation between Functional Movement Screening (FMS) results and ROM in lower limb joints. Methods : Forty-eight young middle distance runners (26 men and 22 women) performed an FMS test and a ROM test of the lower limb joints. Nonparametric testing was used to compare the ROM of left and right lower extremities, an independent-sample T -test was used to compare FMS test scores between left and right sides, and Spearman correlation was used to analyze relationships between FMS test results and ROM of lower limb joints. Results : A negative correlation was observed between left hurdle step and ROM of right knee flexion (r = –0.435, p < 0.05), while a positive correlation was observed between right hurdle step and ROM of right ankle flexion (r = 0.392, p < 0.05). A negative correlation was observed between left in-line lunge and ROM of left knee flexion (r = –0.508, p < 0.05), while a positive correlation was observed between right in-line lunge and ROM of right hip extension (r = 0.445, p < 0.05). A positive correlation was observed between left active straight-leg-raise and ROM of left hip flexion (r = 0.464, p < 0.05), and a positive correlation between right rotary stability and ROM of right ankle extension (r = 0.393, p < 0.05). The trunk-stability push-up and ROM of left ankle flexion was negatively correlated (r = –0.446, p < 0.01). Conclusions : FMS test results were significantly correlated with ROM of hip, knee and ankle joints on the sagittal plane, with differences observed between the left and right sides. The ROM of flexion, extension of hip and extension of ankle were positively correlated with the FMS test results, while larger knee flexion and ankle flexion ROM were negatively correlated with FMS test results. We propose that excessive ROM of the knee and ankle could affect the development of stability. The results of this study should help to further our understanding of FMS.
Association of Gestational Hypertension with Anemia under 5 Years Old: Two Large Longitudinal Chinese Birth Cohorts

Gestational hypertension may interfere with the placental iron metabolism, thus probably increasing the risk of childhood anemia. We aim to examine the association between gestational hypertension and childhood anemia at different ages in two large Chinese birth cohorts. Cohort 1 was conducted in 5 counties in northern China and was comprised of 17,264 mother–children pairs (97.3%) during 2006–2009, whereas cohort 2 was conducted in 21 counties in southern China and was comprised of 185,093 mother–children pairs (93.8%) during 1993–1996. All pregnant women were registered in a monitoring system and followed up until the termination of pregnancies. The childhood anemia was diagnosed at 6 month and 12 month in cohort 1 and at 55 month in cohort 2. The overall incidence of childhood anemia was 6.78% and 5.28% at 6 month and 12 month, respectively, in cohort 1 and 13.18% at 55 month in cohort 2. Gestational hypertension was associated with increased risk of anemia at 6 month (adjusted Odds Ratio (OR): 1.31; 95% confidence interval (CI): 1.05, 1.63) and at 12 month (adjusted OR: 1.50; 95% CI: 1.18, 1.90) in cohort 1 and at 55 month (adjusted OR: 1.06; 95% CI: 1.01, 1.12) in cohort 2. The hemoglobin values of children at different ages were lower among gestational hypertension group in the linear models, which was consistent with the results of binary regression analysis. Our study found gestational hypertension may associate with an increased risk of childhood anemia. It suggests a possible need for exploring changes in prenatal care that might prevent childhood anemia.
A HOLISTIC APPROACH FOR INSPECTION OF CIVIL INFRASTRUCTURES BASED ON COMPUTER VISION TECHNIQUES

Abstract. In this work, it is examined the 2D recognition and 3D modelling of concrete tunnel cracks, through visual cues. At the time being, the structural integrity inspection of large-scale infrastructures is mainly performed through visual observations by human inspectors, who identify structural defects, rate them and, then, categorize their severity. The described approach targets at minimum human intervention, for autonomous inspection of civil infrastructures. The shortfalls of existing approaches in crack assessment are being addressed by proposing a novel detection scheme. Although efforts have been made in the field, synergies among proposed techniques are still missing. The holistic approach of this paper exploits the state of the art techniques of pattern recognition and stereo-matching, in order to build accurate 3D crack models. The innovation lies in the hybrid approach for the CNN detector initialization, and the use of the modified census transformation for stereo matching along with a binary fusion of two state-of-the-art optimization schemes. The described approach manages to deal with images of harsh radiometry, along with severe radiometric differences in the stereo pair. The effectiveness of this workflow is evaluated on a real dataset gathered in highway and railway tunnels. What is promising is that the computer vision workflow described in this work can be transferred, with adaptations of course, to other infrastructure such as pipelines, bridges and large industrial facilities that are in the need of continuous state assessment during their operational life cycle.
Frequent Spindle Assembly Errors Require Structural Rearrangement to Complete Meiosis in Zea mays

The success of an organism is contingent upon its ability to faithfully pass on its genetic material. In the meiosis of many species, the process of chromosome segregation requires that bipolar spindles be formed without the aid of dedicated microtubule organizing centers, such as centrosomes. Here, we describe detailed analyses of acentrosomal spindle assembly and disassembly in time-lapse images, from live meiotic cells of Zea mays. Microtubules organized on the nuclear envelope with a perinuclear ring structure until nuclear envelope breakdown, at which point microtubules began bundling into a bipolar form. However, the process and timing of spindle assembly was highly variable, with frequent assembly errors in both meiosis I and II. Approximately 61% of cells formed incorrect spindle morphologies, with the most prevalent being tripolar spindles. The erroneous spindles were actively rearranged to bipolar through a coalescence of poles before proceeding to anaphase. Spindle disassembly occurred as a two-state process with a slow depolymerization, followed by a quick collapse. The results demonstrate that maize meiosis I and II spindle assembly is remarkably fluid in the early assembly stages, but otherwise proceeds through a predictable series of events.
Pre-competition mental energy and performance relationships among physically disabled table tennis players

Energy is essential to human daily functioning and performance. However, the association of mental energy with athletes’ performance has rarely been examined. We attempted to examine the pre-competition mental energy–performance relationships by two studies. Study 1 administered Athletic Mental Energy Scale (AMES, Lu et al., 2018) to nine elite physically-disabled table tennis players one day before competition in 5 international tournaments. Then, we collected their subjective performance after each competition. In Study 2, we sampled 77 National-level physically-disabled table tennis players and examined the pre-competition mental energy-performance relationship as the procedure in Study 1. Results from Study 1 provided initial findings of how pre-competition mental energy is associated with performance and portrayed in elite physically-disabled table tennis players. Results from Study 2 further confirmed the pre-competition mental energy- performance relationships. We suggested future studies to examine the mental energy–performance relationships in physically-disabled and abled athletes and different sports.
