Masking directions: teacher instructions and COVID-19 protocols
Authors: LeBlanc Robert Jean 
Published: September 2023

Abstract
The arrival of COVID-19 disrupted the everyday life of the classroom. This interactional sociolinguistic research explores a teacher providing directions to students about COVID-19 safety protocols, delivered on the first three days of the students’ return to the classroom in August 2020 after a multi-month hiatus. Using audio-data collected over multiple hours as part of an ongoing long-term study of classroom interaction in a rural Canadian high school, it examines teacher strategies for delivering directives regarding COVID-19 safety policy, with particular attention to linguistic forms aimed at student compliance during the fraught early days of return. The findings outline strategies of delivering unambiguous directives regarding relatively mundane procedures, as well as strategies of avoidance—indirections—which were framed as negotiation and revoicing. This study explores the tenuous balance of risk and the everyday in the classroom, where the teacher attempts to reset the interactional order in light of new restrictions, new requirements, and new threats.

Zusammenfassung
In dieser Arbeit werden die zukünftigen Alterseinkommen der heute Vorsorgenden in den einzelnen Vorsorgewegen im Kontext des Drei-Schichten-Modells und die daraus resultierenden Ersatzquoten untersucht. Die Betrachtung des gesamten Alterssicherungsniveaus ist notwendig, um rentenpolitische Debatten führen und Handlungsempfehlungen ableiten zu können. Der Autor zeigt, dass Personen, die ausschließlich über eine Basisversorgung der ersten Schicht abgesichert sind, im Durchschnitt über ein Alterseinkommen von 48 Prozent ihres letzten Bruttoeinkommens verfügen. Wird zusätzlich zur ersten auch in der zweiten Schicht vorgesorgt, weisen die Versicherten eine Ersatzquote von 63,1 Prozent auf. Personen, die in allen drei Schichten vorsorgen, zeigen eine Ersatzquote von 82,1 Prozent.
Geometría de la dualidad en <em>El invierno de los jilgueros</em> de Mohamed El Morabet
Authors: Gnaoui Younes 
Published: September 2023

Las nociones de desierto, mar, horizonte y doble desempeñan una importancia sustancial en El invierno de los jilgueros de Mohamed El Morabet. Los cuatro motivos logran diseñar y disponer una sutil geometría de tensiones dicotómicas que vertebran la compostura narrativa de la novela. El presente artículo se propone acercar las manifestaciones que cobran tales motivos, con el fin de presentar una lectura interpretativa del significado que adquieren dentro de la obra. El objetivo principal es dar cuenta de los mecanismos de articulación de esos motivos que van urdiendo en la trama narrativa una atinada y discreta cartografía de dualidades y simetrías, de cara a polarizar el sentido global del texto novelístico.

Published: September 2023

This study aimed to determine the concentrations of the lignans pinoresinol, secoisolariciresinol, matairesinol and isolariciresinol in white wines aged in twelve different oak barrels originating from different cooperages and regions and with different toasting levels. In a two-year experiment the influence of oak barrels and of variety on lignan content was monitored. The results of this study show that the use of oak barrels affects only syringaresinol concentrations. Wines from low-releasing barrels contained mean concentrations of 20-50 ng/ml of syringaresinol, while wines from high-releasing barrels contained mean concentrations of 140-160 ng/ml of syringaresinol. Wines from the other barrels contained mean concentrations of 70-100 ng/ml of syringaresinol. The amounts of matairesinol and pinoresinol were affected by grapevine cultivar. In Veltliner Grün, the mean matairesinol concentration was significantly higher than in all other cultivars except for Chardonnay (mean concentrations 11, 6 and 3-5 ng/ml in Veltliner Grün, Chardonnay and other cultivars respectively). The amounts of isolariciresinol and secoisolariciresinol and total amount of lignan aglycones were affected by the interaction of cultivar and year. The mean concentrations of both lignans and total aglycone were significantly higher in Chardonnay from 2017 (210, 120 and 460 ng/ml for isolariciresinol, secoisolariciresinol and total aglycones respectively) than in all the other samples (60-130, 0-50 and 180-280 ng/ml for isolariciresinol, secoisolariciresinol and total aglycones respectively).

Published: September 2023

Attrition rates for Black youths in mental health treatment settings are high, and the extant literature suggests this may be because treatment is not meeting their unique needs. Public health professionals, defined here as all individuals who work to increase the well-being of youths, can play a major role in changing these outcomes. The purpose of this article is to suggest a broader scope of practice, or a redefined role, for public health professionals who work with Black youths seeking outpatient mental health care and to explicate ways in which training and mentoring can help accomplish this goal. Bolstered by a socioecological conceptual model, we suggest 3 standards of practice that we believe must be satisfied to meet the requirement for this redefined public health professional role: using a sociocultural framework, exercising flexibility in one’s assigned role, and understanding and incorporating culturally specific strengths and protective factors into care.

Objectives. To evaluate community-wide prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection using stratified simple random sampling. Methods. We obtained data for the prevalence of SARS-CoV-2 in Jefferson County, Kentucky, from adult random (n = 7296) and volunteer (n = 7919) sampling over 8 waves from June 2020 through August 2021. We compared results with administratively reported rates of COVID-19. Results. Randomized and volunteer samples produced equivalent prevalence estimates (P < .001), which exceeded the administratively reported rates of prevalence. Differences between them decreased as time passed, likely because of seroprevalence temporal detection limitations. Conclusions. Structured targeted sampling for seropositivity against SARS-CoV-2, randomized or voluntary, provided better estimates of prevalence than administrative estimates based on incident disease. A low response rate to stratified simple random sampling may produce quantified disease prevalence estimates similar to a volunteer sample. Public Health Implications. Randomized targeted and invited sampling approaches provided better estimates of disease prevalence than administratively reported data. Cost and time permitting, targeted sampling is a superior modality for estimating community-wide prevalence of infectious disease, especially among Black individuals and those living in disadvantaged neighborhoods.

Abstract
Background
Branched-chain amino acid (BCAA) supplementation is one of the most popular strategies used by the general population and athletes to reduce muscle soreness and accelerate the recovery process of muscle damage biomarkers after an intense exercise or training session.
Objectives
This systematic review and meta-analysis investigated the effects of BCAA supplementation on muscle damage biomarkers and muscle soreness after exercise-induced muscle damage (EIMD).
Methods
The systematic literature search for randomized controlled trials was conducted using seven databases, up to September 13th, 2022. The eligibility criteria for selecting studies were as follows: studies performed on healthy active participants, using BCAA at least once, controlled with a placebo or control group, performing resistance or endurance exercises, and followed up at least once post-EIMD. The methodological quality of the studies was assessed using the “SIGN RCT checklist”. Random-effects meta-analyses were processed to compute the standardized mean difference (Hedges’ g). Meta-regression analyses were completed with daily and total dosage and supplementation as continuous moderator variables.
Results
Of the 18 studies included in this study, 13 were of high quality and five were of acceptable quality. Our results revealed BCAA supplementation elicits a significant effect on reducing creatine kinase (CK) levels immediately (g=-0.44; p = 0.006) and 72 h (g=-0.99; p = 0.002), but not 24 h, 48 h, and 96 h post-EIMD. Additionally, a significant effect on delayed onset of muscle soreness (DOMS) was identified at 24 h (g=-1.34; p < 0.001), 48 h (g=-1.75; p < 0.001), 72 h (g=-1.82; p < 0.001), and 96 h (g=-0.82; p = 0.008), but not immediately post-EIMD. No significant effect was found on lactate dehydrogenase (LDH) levels at any time point. Meta-regression indicated higher daily and total dosages of BCAA, and longer supplementation periods were related to the largest beneficial effects on CK (total dosage and supplementation period) at 48 h, and on DOMS at 24 h (only daily dosage).
Conclusion
The overall effects of BCAA supplementation could be considered useful for lowering CK and DOMS after EIMD, but not LDH. The longer supplementation period prior to the EIMD could be more effective for CK and DOMS reduction.

Abstract
Cryptographic algorithm identification is the process of distinguishing or identifying the cryptographic algorithm by analysing the potential information of various features in the ciphertext under the condition of known ciphertext, which is the basis of cryptanalysis work. To solve the worse identification accuracy and stability problem of the single-layer scheme in cryptographic algorithm identification work as the complexity of ciphertext enhances, the interference between ciphertext data and the number of encryption algorithms increases, we propose a cryptographic algorithm identification scheme of block cipher algorithm using deep learning algorithm Multi-Layer Perception (MLP) in this paper. In this scheme, 15 NIST randomness test methods are used to extract ciphertext feature, and 10 meaningful features are selected as input to MLP classifier to make predictions. In the ciphertext-only scenario, five block cipher algorithms, AES, 3DES, Blowfish, CAST, and RC2, are selected for the study of cryptographic algorithm identification, then binary classification and multiclassification identification are carried out. The experimental results demonstrate that, when the size of the ciphertext files and other experimental conditions are the same as for the five conventional machine learning models, the proposed scheme has superior accuracy and stability. Among them, the average identification accuracy of binary classification is 76.5% for ciphertext files of 1kB to 512kB size, which is 35.3%, 37.5%, 34.2%, 38.5%, and 41.6% higher than that of the traditional classical machine learning models SVM, GNB, KNN, RF, and LR respectively. The average identification accuracy of the multiclassification is 36.2%, which is significantly higher than the other five classical machine learning algorithms. When the ciphertext file sizes are different, among the identification rates of the six models fluctuate, the MLP model has the greatest stability and the least amount of influence.

Abstract
Flyrock is a major environmental and safety issue during mine production blasting. This can affect workers’ safety and efficiency. Blasting in mines can cause rock fragments to travel far to endanger workers, machinery, and nearby structures. Also, many rock excavation projects anticipated fly-rocks and prevent its impact. This study uses Long Short-term memory networks and seven other machine learning methods to predict the Akoko Edo dolomite Quarries' fly-rock distance. Two hundred and fifty-eight (258) blasting data samples were obtained for model-building. Fly-rock prediction was created using LSTM machine learning. The proposed LSTM fly-rock prediction model was tested using bidirectional recurrent neural networks (BRNN), support vector regressions (SVR-S, SVR-RBF, SVR-L, and SVR-P), and random forest (RF) models. Each modeling method is detailed enough for other scientists to replicate. The top three influencing parameters, which have different correlations with fly-rock, were used to create a fly-rock possibility assessment chart. After testing and training, each machine-learning method was compared. The model error analysis indices and coefficient of determination showed that the LSTM model was the best at predicting fly-rock distance. By accurately predicting fly-rock distance, the LSTM prediction model will go a long way to improve blast area reliability and safety.

Abstract
To evaluate α-tocopherol supplementation on in vitro maturation of oocytes and their embryonic development, maturation, cleavage, blastulation and blastocyst expansion of 1019 high- and low-quality oocytes supplemented with 100, 200, 400 µL of α-tocopherol or ethanol during maturation were evaluated. Maturation rate of high-quality oocytes was similar in all groups. Low-quality oocytes with 400 μL matured less than 100, 200 μL, control and ethanol. High-quality oocytes with 400 μL cleaved more than 100 μL, 200 μL, control and ethanol. Quality of oocytes in same treatment differed only in the 400 μL group, as high-quality oocytes cleaved more than low-quality oocytes. Blastocysts from high-quality oocytes, expanded more with 400 μL than 100 μL, 200 μL, control and ethanol. With 400 μL, a higher proportion of expanded blastocysts was observed in high and low-quality grades. Addition of α-tocopherol did not show cytotoxicity in terms of maturation rates. Addition of 400 µL of α-tocopherol resulted in higher cleavage and expanded blastocysts rates.

Abstract
Background

Maternal anemia is a major public health problem that has detrimental effects on pregnancy and birth outcomes. The threat of food insecurity and nutritional deficiencies is growing as a result of the COVID-19 pandemic. The aim of this study was to determine the prevalence and risk factors of anemia among pregnant women in East Lombok during the pandemic.

Methods

This community-based cross-sectional study is part of an observational cohort study entitled “UKRI-GCRF Action Against Stunting Hub (AASH)” in rural areas of East Lombok, Indonesia, from August 2021 to February 2022. Data were collected from women (18-40 years) in their third trimester pregnancy (N=446). Data collection included hemoglobin, mid-upper arm circumference, intestinal helminth infections, and structured questionnaires for sociodemographic, dietary diversity, pregnancy-related, reduced coping strategy index and COVID-19-related variables. The association between anemia and its determinants was analyzed using binary logistic regression model.

Results

Anemia was found in 40.8% of pregnant women. During the pandemic, 74.7% and 28.9% of women reported a decrease in household income and food expenditure whereas 47% of them reported having medium-to-high coping strategies against the pandemic. Higher RCSI scores (≥5) was associated with food insecurity, decrease in household income, older age (>35 years), low education level, multiparity, receiving government assistance targeted for poor families, but with contraceptive use. In logistic regression, anemia was significantly associated with chronic energy deficiency (CED, AOR=1.92; 95%CI: 1.06-3.48), inadequate dietary diversity (AOR=1.58; 95%CI: 1.02-2.45), and non-use of contraception (AOR=1.58; 95%CI: 1.02-2.45).

Conclusions

CED, inadequate dietary diversity, and non-use of contraception were major contributors to anemia in pregnancy in the area. The findings highlight the importance of improving anemia control program among pregnant women in rural areas like East Lombok and improving policy to strengthen their resilience to natural phenomenon such as COVID-19.
Association between Triglyceride Glucose Index and Related Parameters and Nonalcoholic Fatty Liver Disease
Authors: huang changbo , xiong guang , ruan huaqiang , yao li , zou jun , huang jiean 
Published: September 2023

Abstract
Background: In recent years, parameters related to obesity or insulin resistance, such as triglyceride glucose index (TyG), triglyceride glucose-body mass index (TyG-BMI), triglyceride glucose-waist circumference index (TyG-WC), triglyceride glucose-waist-to-height index (TyG-WHtR), triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL), hepatic steatosis index (HSI), visceral adiposity index (VAI), lipid accumulation product (LAP) and so on, have been proposed to predict the risk of nonalcoholic fatty liver disease (NAFLD). But few studies have compared their value to recognize NAFLD in the general population. This study aimed to compare the ability of TyG index and related parameters (TyG-BMI, TyG-WC, TyG-WHtR) with other parameters to predict NAFLD risk.
Methods: This was a cross-sectional study of fatty liver based on FibroTouch. A total of 612 subjects were included. TyG index and other parameters were calculated according to the original formula, and the OR value of each indicator was calculated by Logistic regression, as well as the area under the curve (AUC) was analyzed by receiver operating characteristic (ROC) analysis, so as to compare the relationship between each parameter and NAFLD.
Results: Among all the parameters analyzed, LAP had the strongest correlation with NAFLD (OR=1.77, P < 0.01), and TyG index related parameters (Tyg-BMI, TyG-WC, TyG-WHtR) had stronger correlation with NAFLD than TyG index. In ROC analysis, TyG-BMI had the highest predictive value in identifying NAFLD (AUC=0.794, 95%CI: 0.7591-0.8289), and had relatively stable predictive value in both diabetic and hypertriglyceridemia groups. It indicates the potential of TyG-BMI in identifying NAFLD in the general population.
Conclusions: Our study showed that TyG index related parameters had better predictive value for NAFLD than TyG index, among which Tyg-BMI index had the best predictive value. TyG index related parameters may be applied to the identification of NAFLD risk in the general population.
