Dans un contexte de crise alimentaire, l’utilisation de ressources locales comme le moringa est primordiale pour réduire la dépendance vis-à-vis des denrées importées. C’est dans cette optique qu’une enquête a été menée dans cinq (5) marchés de la communauté urbaine de Niamey (CUN) pour inventorier les produits et sous-produits du Moringa oleifera. A cet effet, une enquête descriptive, avec un échantillonnage par commodité, est effectuée à l’aide d’un questionnaire semi-ouvert et traité avec SPSS version 20. Au total 25 commerçants ont été enquêtés, réparties dans 5 marchés de Niamey (harobanda, dolé, wadata, dar es salam et katako).Il ressort de cette étude que 80% des enquêtés sont mariés et 48% sont analphabètes. La vente du moringa est assurée à 56% par les femmes. Les feuilles fraiches sont les plus commercialisées (72%) et les formes transformées (séchées et précuites séchées) occupent le 20% des produits. Le Moringa frais provient essentiellement des contrées qui longent le fleuve comme balleyara, torodi, saguia, et gourma. Le Moringa transformé provient principalement de la région de Maradi. Deux variétés du Moringa (la variété locale et la variété pkm-1) sont observées dont les prix varie de 5000F à 50000F le sac selon la saison. Les enquêtés connaissent à 84% les utilisations nutritionnelles et médicinales (diabète, hypertension artérielle, l’ulcère) du moringa. Le mouillage (44%) reste la principale méthode de conservation de ces feuilles.
In a context of food crisis, the use of local resources such as Moringa oleifera is essential to reduce dependence on imported food it is with this in mind that a survey was carried out in five (5) markets of the Niamey urban community (CUN) to inventory the products and by-products of Moringa oleifera. To this end, a descriptive survey, with sampling for convenience, is carried out using a semi-open questionnaire. 25 traders were surveyed, spread over five markets in Niamey (harobanda, dolé, wadata, dar es salam and katako).
It emerges from this study that 80% of the respondents are married and 48% are illiterate. Women sell 56% of Moringa. Fresh leaves are the most sold (72%) and processed forms (dried and pre-cooked dried) occupy 20% of the products. The fresh Moringa comes mainly from the regions that run along the river such as balleyara, torodi, saguia, and gourma…and the processed Moringa comes mainly from the Maradi region. Two varieties of Moringa (the local variety and the pkm-1 variety) are observed, the prices of which vary from 5000F to 50000F per bag depending on the season. Eighty four % of the respondents know the nutritional and medicinal uses (diabetes, arterial hypertension, and ulcer) of moringa. Wetting (44%) remains the main method of preserving these leaves.
The Effects and Implications of Using Open Educational Resources in Secondary Schools
Authors: Harvey Paul , Bond John 
Published: May 2022

Open educational resources (OER) constitute a curriculum innovation that is considered revolutionary and has the potential to change the landscape of curriculum at all levels and content areas. OER have gained attention and widespread acceptance by educators and policy makers since 2002. The promise of OER is that they provide cost savings, promote collaboration, and are adaptable to the needs of teachers and students while providing a legitimate alternative to commercially produced print textbooks. Determining the relevance and viability of the movement to embrace OER requires an examination of theoretical foundations and empirical research to illuminate the effect of using OER as core curricula. While advocates promote the use of OER as a financially liberating model of curriculum and as a source of constructivist learning materials, more research is needed. The purpose of this study was to examine the relationship between OER and student learning. The study critically analyzed previous studies on OER and applied empirical analyses to the use of OER by a sample of middle schools. Twenty-eight middle schools from Washington State served as the subjects for the study. The study followed an ex post facto causal comparative model. Three research questions provided the focus for the study to investigate the effects of OER curriculum, duration of curriculum use, and other factors on student achievement in middle school mathematics. The results of the study found non-significant effects for OER use in relationship to school performance in mathematics, and significant effects on math scores for the variables of student poverty, curriculum duration, and cohort size.
Understanding the Relationship Among Self-efficacy, Utility Value, and the Community of Inquiry Framework in Preservice Teacher Education
Authors: Akcaoglu Mete , Akcaoglu Mustafa Ozturk 
Published: May 2022

School closures during the COVID-19 pandemic have shown the importance of distance education, and teachers have been tasked with designing and delivering online courses in a short amount of time without much preparation or deliberation. As the future generation of teachers, preservice teachers need to be prepared to teach online, and their motivation to do so is a key factor in how successfully they do it. The community of inquiry framework provides researchers and practitioners with a framework for designing and delivering online courses, while self-efficacy and utility value are important motivational constructs predicting future engagement and success in tasks. In this cross-sectional survey study, we investigated preservice teachers’ (n = 344) perceptions of their self-efficacy, utility value, the importance of the three components of the community of inquiry framework: teaching presence, social presence, and cognitive presence. Our results show that overall, preservice teachers had high motivation to teach online and high perceptions of the three presences. Our regression analyses indicated that while preservice teachers’ self-efficacy was a significant predictor of teaching presence, utility value only significantly predicted social presence. We discuss the implications of these findings for teacher education programs, including a holistic approach to teaching online learning and instructional design.
Analysing network structures and dynamics of the Pakistan stock market across the uncertain time of global pandemic (Covid-19)
Authors: Memon Bilal Ahmed 
Published: May 2022

Purpose ― The global pandemic COVID-19 has attracted considerable interest from researchers globally. However, there is very little systematic work on the impact of the COVID-19 crisis on the local stock markets. This paper proposes a complex network method that examines the effects of global pandemic COVID-19 on the Pakistan stock market to fill in these gaps.
Methods ― Firstly, correlograms are plotted to inspect the correlation matrices of the overall and two sub-sample periods. Secondly, correlation threshold networks and topological properties are examined for different threshold levels. Finally, this paper uses evolving MSTs to construct a dynamical complex network and presents dynamic centrality measures, normalised tree, and average path lengths.
Findings ― The findings show that COVID-19 related certainty and crisis lead to low volatility and a star-like structure, resulting in a quick flow of information and a strong correlation among the Pakistan stock market.
Implication ― This analysis would help investors and regulators to manage the Pakistan stock market better. In addition, the comprehensive study solely on the Pakistan stock market will be helpful for Pakistan government officials and stock market participants to assess and predict the risks of the Pakistan stock market associated with the global pandemic COVID-19.
Originality ― This paper addresses both classes of the networks. To the best of our knowledge, the static and dynamic evolution of the Pakistan stock market around the global pandemic COVID-19 has not been performed yet.
SINODALIDADE COMO “ESTILO”

Published: May 2022

John O’Malley SJ, historiador norte-americano, pesquisando o Concílio Vaticano II, chamou a atenção para o fato de que estilo não é questão de adorno da linguagem, mas expressão da verdade mais íntima e mais profunda do sujeito. É o jeito de ser (O’MALLEY, 2014). A sinodalidade é um novo modo de ser Igreja e, portanto, um novo “estilo”: uma Igreja menos autocrática e mais colaborativa, uma Igreja pronta a ouvir e levar em consideração os diferentes pontos de vista, uma Igreja aberta e transparente, menos unilateral nas tomadas de decisão, comprometida com a equidade e trabalhando com pessoas e instituições fora da comunidade católica, uma Igreja que presume a inocência enquanto não se prove a culpa, que se abstenha de juramentos secretos, denúncias anônimas e táticas inquisitoriais. Essa era a proposta de João XXIII para atualizar a Igreja, tal como expressou no discurso programático Gaudet Mater Ecclesia, com que inaugurou o Concílio (...)

This study examines the experiences of IDLE activities based on the ACTIONS model (Access, Cost, Teaching and learning, Interactivity and user-friendliness, Organizational issues, Novelty, and Speed) which focused on vocabulary. The results of the study are intended to be a self-reflection on the factors involved in creating English vocabulary quizzes on Instagram as IDLE sources for higher education students. The study aims to use social media, especially Instagram, as a learning tool in a digital context. The researcher uses written narratives that contain her experiences in creating such English vocabulary quizzes. For that reason, the study participant is the researcher herself, a 21-year-old female undergraduate student in the English Education Department. In the study, the researcher uses thematic analysis to analyse the narrative data. This includes three activities: 1) repeated reading of the data; 2) coding and categorising the data extracts; and 3) recognising the thematic headings. The results show that creating IDLE activities based on the ACTIONS model leads to flexibility of access, affordable costs, teaching and learning needs based on followers' feedback and correction, excellent interactivity and user-friendliness, no organisational issues, novelty, and speed. The study offers new insights into how English pre-service teachers' engagement with IDLE serves as a significant factor in their future teaching tasks. </span></p></div></div></div></div></div></div>

Tension tuning of sound and heat transport in graphene
Authors: Liu Hanqing , Lee Martin , Šiškins Makars , Zant Herre van der , Steeneken Peter , Verbiest Gerard 
Published: May 2022

Abstract
Heat transport by acoustic phonons in 2D materials is fundamentally different from that in 3D crystals because the out-of-plane phonons propagate in a unique way that strongly depends on tension and bending rigidity. Since in-plane and out-of-plane phonon baths are decoupled, initial studies suggested they provide independent pathways for heat transport and storage in 2D materials. Here, we induce tension in freestanding graphene membranes by electrostatic force, and use optomechanical techniques to demonstrate that it can change the rate of heat transport by as much as 33%. Using a ballistic Debye model, we account for these observations and extract the average bending rigidity of the flexural acoustic phonons, which increases approximately linearly with the membrane's areal mass density, in contrast to the cubic dependence seen in bulk structures. Thus, we not only elucidate phononic heat transport mechanisms in suspended 2D materials, but also provide a promising route for controlling nanoscale heat transport by tension.
The characteristics of compound climate extremes from the perspective of compound droughts and heatwaves over the Huai River Basin of China from 1961 to 2017
Authors: Wang Weijiao , Ren Shoujia 
Published: May 2022

Abstract
Compound droughts and heatwaves have caused serious impacts on human activities, social economy and ecological environment. Droughts are usually caused by precipitation shortage. Recent studies found that with the continuous global warming, the impact of temperature rise on the compound events of drought and heatwave is further expanding, and it is urgent to carry out research on the temporal and spatial characteristics of compound droughts and heatwaves. The present study examined changes in compound droughts and heatwaves in Huai River Basin (HRB) of China during 1961–2017. The result shows that both frequency and duration of compound droughts and heatwaves increased from 2003–2017. Compound events appeared more often in summer. The more frequent and longer duration of compound droughts and heatwaves occurred in the north of HRB. The results highlight the increased trend of compound droughts and heatwaves and call for improved efforts on assessing the impact of compound extremes.

Abstract
Purpose:Hypocalcaemia after total thyroidectomy (TT) has been effectively avoided with the routine calcium supplementation, but this strategy implies collateral effects and a high overtreatment rate. Levels of intact intra-operatory paratohormone (iPTHio) have been successfully used to predict hypopathyroidism after TT (HypoPTH-TT).This study was designed aiming to assess an easy, universal and reliable method, based on iPTHio determinations to predict HypoPTH-TT in patients undergoing surgery irrespectively of etiology or kind of limphadenectomy. Results after prospective application of selective prophylactic postoperative supplementation (SPPS) are also described.Method: Two-phased observational study. In phase I, percentage decline of iPTHio (ΔiPTHio) and iPTHio at skin closure (iPTHio-SC) of 53 TT and 16 thyroid lobectomy (TL) cases were recorded. Receptive Operative Curves (ROC) were used to calculate the ability of both iPTHio assays to predict hypoPTH-TT. Best cut-off points were calculated and evaluated. In phase II, SPPS was implemented on 202 TT cases guided by cut-off point of Δ-iPTHio. Hypocalcaemia and readmission rates were recorded.Results:ΔiPTHio and iPTHio-SC showed an area under the curve of 0.96 and 0.97 respectively. Best cut-off points were 70% for ΔiPTHio (Sensitivity:0.957; Negative predictive value: 96.6) and 21.50 pg/ml for iPTHio-SC (Sensivity: 0.913; Negative predictive Value: 93.5). All iPTHio-SC were above 14pg/ml when ΔiPTHio < 70%. After implement SPPS based on ΔiPTHio criteria, 110 TT cases (54.5%) were discharged without supplementation, and none were readmitted.Conclusion:ΔiPTHio is an easy, universal and accurate method to predict hypoPTH-TT risk. ΔiPTHio < 70% (whenever iPTHio-SC>14pg/ml) allows SPPS to be applied safely and avoids unnecesary treatment in 54,5 % of the patients.

Abstract
Background: Bovine digital dermatitis (DD) represents a common cause of lameness in cattle both in Taiwan and worldwide. DD can be controlled using footbaths but the traditional use of footbath with copper sulfate is harmful to the environment. Therefore, the objective of this study was to use a quaternary ammonium salt-based disinfectant or a chelated copper-zinc mixture for foot bathing as an alternative to copper sulfate for DD in lactating cows. Moreover, a cleaning pool was established and used prior to the DD foot bathing. Two groups of 27 lactating cows were checked and randomly assigned to two treatment groups, which were 1% quaternary ammonium salt-based disinfectant (BCD) and 2.5% chelated copper-zinc mixture (CZM). The experimental period lasted for 15 consecutive weeks and a footbath was performed once a week. Results: The cure rate proportion in the BCD group was significantly higher than the CZM, measuring at 67% and 38%, respectively (P = 0.03). The logistic regression analyses indicated that the odds (95% CI) for the cure rate in the CZM group was 0.30 (0.095–0.948) times than in the BCD group (P = 0.04). Following the 15 weeks of treatment, both the BCD and CZM groups exhibited a significant increase of M0 in all cows (P < 0.05). Moreover, the proportion of M2, M3, and M4 in the BCD group was significantly decreased (P < 0.05). Similarly, the M2 proportion was significantly decreased in the CZM group, while the M1 proportion was significantly increased (P < 0.05). The proportion of cows with M0 in BCD was significantly higher at the end of the experiment than those in the CZM group (P < 0.05). The proportion of M1, M2, M3, and M4 demonstrated no difference between the BCD and CZM treatments at each stage (P > 0.05).Conclusion: The results illustrated that establishing a cleaning pool prior to foot bathing, in addition to, a weekly footbath with a 1% quaternary ammonium salt-based disinfectant, provided additional control over the prevalence of DD.

Abstract
Purpose
This study aimed to validate different low-density lipoprotein cholesterol (LDL-C) estimating equations in the Turkish population, composed of children and adolescents.
Methods
In this study at Sivas Cumhuriyet University Hospital in Sivas (Turkey), a total of 3,908 children under the age of 18 were included. LDL-C was directly measured by direct homogeneous assays such as Roche, Beckman, and Siemens and was predicted by Friedewald’s, Martin-Hopkins’, extended Martin-Hopkins’ and Sampson’s formulas. Firstly, the concordances between the predictions obtained by the direct measurements and formulas were calculated, and then, these results were evaluated both overall and separately for the LDL-C, triglycerides (TG), and non-high-density lipoprotein cholesterol (non-HDL-C) sublevels. Linear regression analysis was performed, and residual error plots were generated between each prediction and direct measurement method. Coefficient of determination (R2) and mean absolute deviations were also evaluated.
Results
The overall concordance of the Friedewald, Sampson, Martin-Hopkins and the extended Martin-Hopkins formula were 64.6%, 69.9%, 69.4%, and 84.3% for the Roche direct assay, 69.8%, 71.6%, 73.6% and 80.4% for the Siemens direct assay, 66.5%, 68.8%, 68.9% and 82.1% for the Beckman direct assay, respectively. The extended Martin-Hopkins formula had the highest concordance coefficient in both overall and all sublevels of LDL-C, non-HDL-C, and TG. When estimating the LDL-C categories, the highest underestimation degrees were obtained with the Friedewald formula.
Conclusions
Our analysis, conducted in a large pediatric population, showed that the extended Martin-Hopkins equation gives more reliable results in predicting LDL-C compared to other equations.

Abstract
Machine learning, especially deep learning, has been increasingly becoming a potentially powerful tool in the diagnosis and management of diseases. In this study, we utilized logistic regression (LR), decision tree (DT), gradient boosted decision tree (GBDT), support vector machine (SVM), and deep multilayer perceptron (MLP) as machine learning models to rapidly diagnose the mycoplasma pneumoniae pneumonia (MPP) in children patients. The classification task was carried out after applying the preprocessing procedure to the MPP dataset. The most efficient results are obtained by GBDT. It provides the best performance with an accuracy of 93.7%. In contrast to standard raw feature weighting, the feature importance takes the underlying correlation structure of the features into account. The most crucial feature of GBDT is the “pulmonary infiltrates range” with a score of 0.5925, followed by “cough” (0.0953) and “pleural effusion” (0.0492). We publicly share our full implementation with the dataset and trained models at https://github.com/zhenguonie/2021_AI4MPP.
