Table_1_Factors influencing secondary school students’ reading literacy: An analysis based on XGBoost and SHAP methods.docx

This paper constructs a predictive model of student reading literacy based on data from students who participated in the Program for International Student Assessment (PISA 2018) from four provinces/municipalities of China, i.e., Beijing, Shanghai, Jiangsu and Zhejiang. We calculated the contribution of influencing factors in the model by using eXtreme Gradient Boosting (XGBoost) algorithm and sHapley additive exPlanations (SHAP) values, and get the following findings: (1) Factors that have the greatest impact on students’ reading literacy are from individual and family levels, with school-level factors taking a relative back seat. (2) The most important influencing factors at individual level are reading metacognition and reading interest. (3) The most important factors at family level are ESCS (index of economic, social and cultural status) and language environment, and dialect is negative for reading literacy, whereas proficiency in both a dialect and Mandarin plays a positive role. (4) At the school level, the most important factors are time dedicated to learning and class discipline, and we found that there is an optimal value for learning time, which suggests that reasonable learning time is beneficial, but overextended learning time may make academic performance worse instead of improving it.</p

Fabrication of Core–Sheath NiCoP@FeP_<i>x</i> Nanoarrays for Efficient Electrocatalytic Hydrogen Evolution

Construction of effective, stable, eco-friendly, and earth-abundant electrocatalysts that substitute noble metals for hydrogen evolution reaction (HER) is essential for developing renewable and clean energy. Here we report a layer-by-layer assembly route to fabricate core–sheath structured nanoarrays composed of nickel cobalt phosphide and iron phosphide (NCP@FeP_<i>x</i>) on a conductive Ni wire by atomic layer deposition (ALD). The as-fabricated multimetallic phosphide exhibits high electrocatalytic activity in both alkaline and acidic media, with small overpotentials of 82.5 and 96 mV at 10 mA cm^–2, respectively. The self-supported electrode displays superior long-term stability and favorable durability. The excellent activity is originated from the unique core–sheath structure, and the synergistic effects of the FePx sheath and the NCP core contributed to the enhanced activity. The present ALD-assisted layer-by-layer strategy may provide a general route for the controlled fabrication of nanostructured electrocatalysts with tunable compositions and surfaces

Image1_Analysis of Climate and Income-Related Factors for High Regional Child Drowning Mortality in China.JPEG

Objectives: To assess the relationship between regional climatic factors and child drowning in China.Methods: Provincial age-specific drowning rate, climatic and income data were collected. We conducted a geographically weighted regression to evaluate the association between drowning and climatic factors. A generalized additive model was used to comprise a bivariate term with which to investigate the interaction of environmental risk factors and whether such interactions influence drowning mortality.Results: In southern China, an abundance of water systems and increased precipitation, as well as hotter and longer summers, lead to significantly higher drowning compared with that in northern China. Long summers and low economic performance in parts of Xinjiang were key factors for its high drowning mortality rate. Linear and nonlinear joint effects were observed between the risk factors of drowning.Conclusion: Different regions should use adaptive measures to reduce drowning risks, for example, communication campaigns during the summer period or when the weather changes.</p

<i>In vitro</i> digestibility test of cell surface and secreted phytases.

<p>A: Measured phosphate (Pi) released from a corn-based diet mixed with cell surface or secreted phytases. B: Simulation of the pelleting process (i.e., incubation for 3 min at 80°C or 5 min at 90°C prior to activity measurement), followed by determination of the amount of released Pi. The levels of released Pi were compared with samples without heat treatment. GS115/ZαA served as a background measurement.</p

<i>Citrobacter amalonaticus</i> Phytase on the Cell Surface of <i>Pichia pastoris</i> Exhibits High pH Stability as a Promising Potential Feed Supplement

<div><p>Phytase expressed and anchored on the cell surface of <i>Pichia pastoris</i> avoids the expensive and time-consuming steps of protein purification and separation. Furthermore, yeast cells with anchored phytase can be used as a whole-cell biocatalyst. In this study, the phytase gene of <i>Citrobacter amalonaticus</i> was fused with the <i>Pichia pastoris</i> glycosylphosphatidylinositol (GPI)-anchored glycoprotein homologue <i>GCW61</i>. Phytase exposed on the cell surface exhibits a high activity of 6413.5 U/g, with an optimal temperature of 60°C. In contrast to secreted phytase, which has an optimal pH of 5.0, phytase presented on the cell surface is characterized by an optimal pH of 3.0. Moreover, our data demonstrate that phytase anchored on the cell surface exhibits higher pH stability than its secreted counterpart. Interestingly, our <i>in vitro</i> digestion experiments demonstrate that phytase attached to the cell surface is a more efficient enzyme than secreted phytase.</p></div
