The construction of a physical literacy assessment index system for junior high school students: a Chinese study

In recent years, the internalisation of education in China has led to an increase in the prevalence of a highly competitive, test-focused approach to learning. This has had a detrimental impact on the physical health and wellbeing of children and adolescents in China, resulting in a concerning lack of physical literacy among junior high school students. Accordingly, the objective of this study is to construct an evaluation index system for physical literacy in junior high school students with Chinese characteristics, quantify the relative importance of each domain, and provide a framework for students to assess and self-evaluate the sustainable development of their physical literacy. The indicator system was modelled on CAPL-2, and valid indicators were extracted from the literature. A pre-selected indicator system for physical literacy in junior high school students was constructed through three rounds of Delphi expert questionnaire surveys (48 questionnaires were distributed in total). A total of 16 experts participated in all three rounds of the surveys until a consensus was reached on the indicators, resulting in the establishment of a hierarchical analysis-based theoretical model. This was developed using the experts’ opinions and determined the items to be subdomains and weights. The AHP was employed to ascertain the relative importance of the subdomains and items within the assessment system. The index weight scores of the Chinese junior high school students’ physical literacy assessment index system are aligned with the core tenet of the physical literacy concept, comprising four primary indicators, eight secondary indicators, and 26 tertiary indicators. The weights of the physical literacy evaluation indexes for junior high school students in China were calculated using the AHP to establish a progressive hierarchical model and the consistency test. The primary indicators were found to be in the following order of importance: Physical Competence (29.82%) > Motivation and Confidence (29.64%) > Knowledge and Understanding (20.27%) = Daily Behavior (20.27%). The system is an effective means of evaluating the impact of physical activity and health promotion among junior high school students, and it effectively addresses the needs of this age group in these areas. It provides a comprehensive assessment of the effects of physical activity and health promotion among junior high school students, and it offers a scientific foundation for the development of precise and individualized physical activity and health promotion programs.

Exploring Plant Growth-Promoting Traits of Endophytic Fungi Isolated from Ligusticum chuanxiong Hort and Their Interaction in Plant Growth and Development.

Endophytic fungi inhabit various plant tissues and organs without inducing evident disease symptoms. They can contribute positively to the growth of plants, bolster plants resilience to environmental and biological stresses, and facilitate the accumulation of secondary metabolites. These microbial resources possess significant developmental and utilization value in various applications. Hence, this study focused on exploring the plant growth-promoting (PGP) traits of 14 endophytic fungi from Ligusticum chuanxiong Hort (CX) and elucidating the effects and mechanisms that facilitate plant growth. According to PGP activity evaluation, the majority of strains demonstrated the capacity to produce IAA (78.57%), siderophores (50.00%), ammonia (35.71%), potassium solubilization (21.43%), nitrogen fixation (57.14%), and phosphate solubilization (42.86%). Further investigations indicated that the levels of IAA ranged from 13.05 to 301.43 μg/mL, whereas the soluble phosphorus levels ranged from 47.32 to 125.95 μg/mL. In cocultivation assays, it was indicated that Fusarium sp. YMY5, Colletotrichum sp. YMY6, Alternaria sp. ZZ10 and Fusarium sp. ZZ13 had a certain promoting effect on lateral root number and fresh weight of tobacco. Furthermore, ZZ10 and ZZ13 significantly enhanced the germination potential, germination index, and vigor index of tobacco seeds. The subsequent potted trials demonstrated that the four endophytic fungi exhibited an enhancement to growth parameters of tobacco to a certain extent. ZZ10 and ZZ13 treatment had the best promotion effect. Inoculation with YMY5 increased the chlorophyll a and total chlorophyll content. ZZ10 and ZZ13 treatment remarkably increased the net photosynthetic rate, soluble sugars and soluble protein content, catalase and peroxidase activities, and lowered malondialdehyde content in tobacco leaves. In addition, YMY5 remarkably elevated superoxide dismutase activities. ZZ13 upregulated the expression of growth-related gene. Among them, ZZ13 had a better growth-promoting effect. In conclusion, these endophytic fungi possessing multi-trait characteristics and the capacity to enhance plant growth exhibit promising potential as biofertilizers or plant growth regulators.

Metal ions-mediated concerted electron-proton transfer enables catalytic oxidation of phenolic contaminants by permanganate

Permanganate has been extensively applied in water treatment due to its ease of handling and high stability. However, the impact of common water constituents, especially metal ions, on permanganate oxidation is poorly understood. Here, we report that many redox-inactive metal ions, such as Ca2+, Mg2+, Zn2+, Cu2+, and Al3+, can enhance the reactivity of permanganate with phenolic compounds. Moreover, the enhancing effects of metal ions are highly pH-dependent with the largest promotion effect obtained at the pH close to phenols’ pKa. Experimental and computational analysis revealed that the oxidation of protonated phenols by permanganate underwent proton-coupled electron transfer (PCET) pathways, regardless of the presence of metal ions. Nonetheless, metal ions could catalyze the concerted electron-proton transfer (CEPT) but exhibited negligible effect on ETPT (electron transfer followed by proton transfer) and PTET (proton transfer followed by electron transfer) reactions, accounting for the pH-dependent effects of metal ions. Correlation between CEPT rate constants and the complexing capability of metal ions with phenols suggested that the co-existing metal ions may coordinate to phenolic O–H group and thus facilitate the CEPT reaction of phenols. This study could shed light on the application of permanganate in real practice and the modulation of CEPT reactions.

Study on the Promotional Effect and Mechanism of New Quality Productive Forces on Green Development

The new quality productive forces have the potential to spur both the green transformation of the industrial structure and innovative advances in green technology, which will further strengthen the foundation for sustainable growth. This study analyzes panel data from 30 provinces between 2012 and 2022 to build an evaluation system for new quality productive forces and green development at the provincial level. The entropy weight TOPSIS approach is used to assign weights to each indicator. Methods including fixed effects, mediation effects, and spatial econometrics are used to examine the contribution of new quality productive forces to green development and its mediation mechanism. The study finds that: (1) New quality productive forces significantly promote green development, and the conclusion still holds after a robustness test using the instrumental variables method and excluding municipalities. (2) The new quality productive forces contribute significantly to green development by improving technology and optimizing industrial structure. (3) The new quality productive forces not only directly enhance the green development level of the region, but also positively influence the green development level of the neighboring regions through the spatial spillover effect. (4) The eastern and central regions are more affected by new productivity in terms of green development. Based on these, efforts should be made to develop new quality productive forces, increase technological research and investment, and promote the development of industrial structure to be more environmentally friendly and efficient to promote green development.

Mobile applications for promoting and supporting breastfeeding: Systematic review and meta-analysis.

Breastfeeding practices require improvement. We performed a systematic review of randomised controlled trials (RCTs) and analytic observational studies to assess effects of mobile applications (apps) aiming to support and promote breastfeeding targeting pregnant women, mothers of infants or their partners, on breastfeeding outcomes. We searched MEDLINE, EMBASE, Cochrane CENTRAL and Association of Computing Machinery Digital Library from 1 July 2008 to 29 November 2022, with lack of coverage of the most recent period before publication date being a limitation of this review. We performed meta-analyses of findings from RCTs on primary outcomes, namely early breastfeeding initiation, exclusive and any breastfeeding rates. Joanna Briggs Institute tools were used for risk of bias assessment. Six RCTs, one quasi-experimental and two cohort studies, mainly from high-income countries, were included. Most studies focused on maternal app usage starting from pregnancy. One study targeted fathers as app-users. Population characteristics, such as parity or delivery mode, apps scope of content and applied active components varied between studies. Main methodological limitations of studies were baseline differences between groups and lack of blinding. Compared to controls, app usage tended to increase the odds of exclusive breastfeeding. This nonsignificant effect was most pronounced at 1-1.5 months (n = 1294, odds ratio 1.45 (95% Confidence Interval, CI 0.83, 2.54), with considerable heterogeneity between studies [I2 77%]), but less so at 3 and 6 months post-partum. The odds of early breastfeeding initiation, any breastfeeding at all time points were similar among groups. However, two cohort studies reported increased odds of exclusive and/or any breastfeeding at different time points. In conclusion, evidence is insufficient to show sustained beneficial effects of breastfeeding promotion and support through mobile apps on breastfeeding rates.

Does government-driven infrastructure boost green innovation? Evidence of new infrastructure plan in China

The role of government-driven investment in improving environmental quality has long been an essential concern of environmental research. Using a spatial difference-in-differences model, this study investigates the influence of government-driven new infrastructure investment on green innovation. Based on a panel dataset of 276 Chinese cities from 2005 to 2019, we find a positive effect of high-speed rail (HSR) and smart city (SC) construction on green innovation. Compared with cities that are unconnected to the HSR network, those that are accessible by HSR experienced a 20.6 % increase in per capita green patents. In addition, being a SC planned by the government is associated with 14.8 % more green patents per capita than other cities. Moreover, government-promoted new infrastructure has significant spatial spillover effects on green innovation in adjacent cities. Regional sensitivity is found in promotional and spatial spillover effects. The findings of our study offer essential insights for developing effective policies for advancing infrastructure modernization and environmental protection simultaneously.

Exploring the promotion effect of low MnCoOx doping for low-temperature NH3-SCR of 13X zeolite synthesized from coal fly ash

Using fly ash rich in SiO2 and Al2O3 to prepare heterogeneous zeolite catalysts is an efficacious pathway for the resource development of solid waste. Herein, 13X zeolite with a rich specific surface area was synthesized from fly ash, and low amount of active components (Mn and Co) was added during the preparation of the 13X zeolite. Finally, a series of low-load xMnyCo/13X denitration catalysts were successfully prepared. The results show that the low supported 1Mn2Co/13X zeolite catalyst exhibits excellent selective catalytic performance, with higher than 80 % NO conversion and more than 90 % N2 selectivity during 150–350 ℃. It also demonstrates excellent resistance to both water and sulfur. Physicochemical characterization analysis indicated that a little Mn and Co were doped on the surface of 13X zeolite did not have a detailed crystal structure. The element Co doping increased the proportion of Mn3+, Mn4+ and Ov on 13X zeolite. The results of in situ DRIFTs demonstrated that the NH3-SCR reaction on the surface of 1Mn2Co/13X zeolite followed both the E-R and L-H mechanisms. Additionally, process simulation results further show that using 1Mn2Co/13X zeolite as an industrial denitration agent can reduce material costs by 64.0 % and operating costs by nearly 20 %.

Inspiring Contributions: Fan Leaders’ Directives and Encouragement in the Chinese Online Celebrity Fan Community

Abstract In the neoliberal era, there is a new phenomenon where numerous fans follow fan leaders’ instructions to make tangible or intangible contributions to support celebrities, which has exacerbated economic polarization. Although past studies have explored fan empowerment in the Internet era, fan leaders’ promotion effect has remained unstudied. This study aimed to discover fan leaders’ role in guiding fans’ contributions in the Chinese fan community. By integrating a two-step flow model and participatory culture theory, it used qualitative content analysis to analyze 410 posts and 972 comments in the Chinese singer Song Yaxuan’s fan community from February 3 to 10, 2023. Through an inductive approach, four main themes were derived from results: (1) task delegation and empowerment; (2) user-friendly instructions and seamless communication; (3) highlighting a sense of crisis and putting pressure on fans; and (4) fostering a collective mindset. The findings revealed fan leaders use different techniques and the top-down structure in the community to encourage fans to give voluntary contributions of money or time to the celebrity’s development. Theoretically, this study showed internal operation logic in Chinese fan community. Practically, the study shed light on how to lessen the harmful consequences of neoliberalism’s features within the Chinese entertainment industry and realize healthy development.

Can E-Commerce Policies Drive Common Wealth Levels —— A Study Based on County-Level Data in China, 2012-2020

Based on national county panel data from 2012 to 2020, this study systematically examines the impact of the comprehensive e-commerce into rural areas demonstration project implemented in rural China on promoting the level of common wealth by applying the multi-period double-difference method (DID). It is found that the e-commerce policy significantly enhances the level of common wealth. Further analysis of the impact mechanism shows that the policy effectively promotes the goal of common prosperity by enhancing the level of rural employment. In addition, the positive effect of the e-commerce policy is strengthened by the increase in the level of local government fiscal expenditure, however, the driving effect of the policy is weakened by the higher level of social consumption. Heterogeneity analyses indicate that the policy's promotional effect is particularly significant in the demonstration counties of the Yangtze River Economic Belt. This paper fills the research gap on the relationship between rural e-commerce policy and the level of common wealth, and provides empirical evidence and policy recommendations for related policy formulation.

Research on the influence of green finance policy on enterprise green innovation

At present, China's economy has entered a new normal, and policies with economic growth as the core can no longer meet the needs of social development. In recent years, China has vigorously promoted the green transformation of economic development, and the construction of a green innovation system has become the only way to improve the ecological environment and promote green development. Green finance, as a financial tool providing services for green industries such as energy conservation, emission reduction and pollution prevention and control, plays an important role in the process of economic green transformation. Green Finance Reform and Innovation Pilot Zone is the latest practice of green finance policy system construction. Under this background, this paper takes the establishment of our country’s Green Finance Reform Innovation Experimental Zone as a quasi-natural experiment, and adopts the panel data of Shanghai and Shenzhen A-share listed companies from 2011 to 2022, this paper discusses the impact of Green Finance Policy on enterprise green innovation by means of multi-period double difference model. The study found that the policy has an obvious driving effect on enterprise green innovation, and the conclusion passed the parallel trend test and placebo test; in addition, the mechanism test results show that the stronger the financing constraints, the promotion effect of green financial innovation policy may weaken.

Enhancing glycerol dry reforming performance through metal promoters: A study on 10Ni/La.Al catalyst with Mo, Sn, and Cd additions

The effect of metal promoters (Mo, Sn, and Cd) on the performance of the 10Ni/La.Al nanocrystalline catalyst in Glycerol Dry Reforming (GDR) was investigated. 2x.10Ni/La.Al (x = Mo, Sn, and Cd) catalysts were prepared using the solid-state method and 10 wt.% Ni and 2 wt.% Mo, Sn, and Cd were added to the catalyst using the impregnation method. The catalysts were characterized by BET, X-ray diffraction, temperature-programmed reduction (TPR), oxidation (TPO), Raman, and scanning electron microscopies (SEM) techniques. It was found that adding Mo caused an increase in glycerol conversion and improved the long-term stability of the 10Ni/La.Al. Furthermore, catalysts with different amounts of promoter loading (2, 4, and 6 wt%) were synthesized to evaluate the optimum amount of Mo. 4Mo.10Ni/La.Al was selected to achieve 58 % glycerol conversion and the best stability.

Optimization of fermentation conditions for Bacillus velezensis TCS001 and evaluation of its growth promotion and disease prevention effects on strawberries

Bacillus velezensis TCS001 is a novel biocontrol bacterium with broad-spectrum antifungal activity and plant growth-promoting effects, holding great potential for development in agricultural production. This study optimized the fermentation conditions for B. velezensis TCS001 through single-factor experiments combined with response surface methodology, and developed a formulation for TCS001 suspension concentrate (TCS001-SC). The efficacy of TCS001-SC to promote the growth of strawberries and to prevent and control strawberry anthracnose was evaluated. The optimal liquid fermentation condition for TCS001 was determined to be 2.89 % soluble peanut cake powder, 3.0 % glucose, 3.0 % soluble starch, 0.002 % FePO4, 0.006 % KCl, 0.6 % NaCl, 0.05 % MgCl2·6H2O, 0.3 % K2HPO4, 0.15 % KH2PO4, 0.05 % CaCO3, 0.005 % MnSO4, a working volume of 31 % (77.5 mL/250 mL), a rotation speed of 173 r/min, a cultivation temperature of 28°C, an inoculum volume of 1.0 %, and a pH of 7.0. The 15 L fermenter upscale culture achieved a spore count of 9.46 × 109 CFU/mL, which was 2.01 times the spore count of 4.7 × 109 CFU/mL before optimization, and a preliminary TCS001-SC was developed with the fermented broth as the main component. Agar plate confrontation tests showed that TCS001 had antifungal activity against five types of anthracnose fungi, with inhibition rates ranging from 70.3 % to 87.2 %. TCS001-SC could promote the growth of strawberries and induce a rapid defense enzyme response in their leaves, enhancing the plant's resistance to pathogens. After treatment, individual strawberry plants showed significant increases in the number of leaves, fresh weight of stems and leaves, root fresh weight, leaf area, plant height, and the content of POD, SOD, CAT enzymes, GA, IAA, and ABA compared to the control.Additionally, it shows good prevention and control effects against strawberry anthracnose, with a control efficacy of 60.45% after five spray treatments at a concentration of 2 × 107 CFU/mL, which is not significantly different from the efficacy of commercial microbial agents such as Bacillus subtilis wettable powder, subsequent field trials will be conducted to determine its potential as a microbial pesticide. This study provides important support for the future industrial production and application of the strain TCS001.

Improvement of okara noodle quality by modifying the soluble/insoluble dietary fibre ratio

This study investigated the effect of okara modified through cellulase hydrolysis and extrusion on noodle quality. Modification increased the soluble dietary fibre/insoluble dietary fibre (SDF/IDF) ratio in okara, improved appearance, cooking, and texture, and reduced starch digestibility of okara noodles. The 4.0 % cellulase enzymolysis-extruded okara noodles exhibited the quality closest to that of wheat noodles, with an estimated glycaemic index (eGI) < 55 (low-GI). As the okara SDF/IDF ratio increased, the water mobility of noodles decreased, indicating that an increase in the SDF/IDF ratio reduced competitive water absorption of okara. In addition, increased SDF/IDF ratio increased β-sheet content and promoted the enhanced hydrogen bond interactions between proteins and polymerisation between gliadin and glutenin. Moreover, the microstructure of noodles with a higher SDF/IDF ratio of okara was more continuous and compact, further confirming the promotional effect of okara with a higher SDF/IDF ratio on the quality of okara noodles.

Role of vitamin E on bovine skeletal-muscle-derived cells from Korean native cattle under heat treatment.

Our study aimed to evaluate the dualistic effect of heat stress on muscle differentiation at different temperatures, and whether vitamin E, a powerful antioxidant, could offset any negative effects, using bovine skeletal-muscle-derived cells (BSMCs) with myogenic properties. The BSMCs were extracted from the skeletal muscle of thirty-month-old Korean native cattle and subjected to myogenic differentiation under three heat exposure conditions: 37°C (control; CON), 39°C (mild heat stress; MHS), and 41°C (severe heat stress; SHS) for 24h with or without vitamin E treatment (NE or VE). After 24h treatments, the cells were returned to 37°C incubators and differentiated until day 6. On day 1, because of the heat exposure, the gene expression of MYOG was the highest in MHS (P = 0.047), suggesting a promotive effect of mild heat stress on myogenic differentiation, while on day 6, compared to CON and MHS, MYOD (P = 0.013) and MYOG (P = 0.029) were the lowest in SHS. Vitamin E treatment also lowered MYOG (P = 0.097), regardless of heat exposure. On day 1, HSPB1 (P = 0.001) and HSP70 (P < 0.001) were the highest in SHS, and an interaction between heat exposure and vitamin E treatment was found on day 6 (P < 0.027). BCL-2 was also the highest on day 1 in SHS (P = 0.05), and an interaction of heat exposure and vitamin E treatment was found on day 1 on BAX expression (P = 0.038). For antioxidant genes, SOD1 (P = 0.002) and GPX1 (P < 0.001) were affected by heat exposure, with the highest levels being observed in SHS, and on day 6, GPX1 was still the highest in SHS (P = 0.027). The fusion index was also affected by heat exposure, showing a decrease in SHS and an increase in MHS compared to CON (P < 0.001). Significant effects were noted from heat exposure (P < 0.001), vitamin E treatment (P < 0.001), and the interaction of heat exposure and vitamin E treatment (P = 0.002) on the protein content. Taken together, our findings provide evidence that vitamin E could ameliorate the harmful effects of heat exposure by modulating heat shock proteins and apoptosis regulators, improving the protein synthesis of BSMCs during myogenic differentiation. These results suggest that vitamin E supplementation could potentially protect muscle development in beef cattle under summer heat stress.

Promoters as social controls to facilitate knowledge sharing, conflict management and innovation project portfolio performance

Organizational control theory emphasizes aligning members' actions with organizational goals through formal and social controls. In innovation management, formal controls like project management or stage‐gate processes are limited to measurable and standardized areas. For situations that are complex, unpredictable and highly idiosyncratic, social controls need to be applied for alignment. Knowledge sharing and competitive conflicts are two such innovation‐related phenomena that elude formal control and instead need social controls for alignment. In this research, we propose that promoters—individuals who actively support innovation—serve as social control agents. While previous research has shown the positive effect of single promoters on individual innovation project success, we propose a comprehensive implementation of all four promoter roles, and we test their joint effect on the intermediate outcomes of knowledge sharing and competitive conflict management facilitating innovation project portfolio performance. Drawing on cross‐industry data of 125 firms collected from 986 employees, this article provides empirical evidence that comprehensive implementation of all four promoter roles enhances knowledge sharing and reduces competitive conflicts, thereby improving innovation project portfolio performance. The research reframes promoters as social control agents, emphasizing their collective necessity for managing complex organizational issues and contributing to overall project success.

Melatonin decreases excessive polyspermy for single oocyte in pigs through the MT2 receptor

Melatonin supplementation during in vitro maturation (IVM) improves porcine oocyte maturation and embryonic development by exerting antioxidative effects. Nevertheless, the mechanism by which melatonin prevents polyspermy after in vitro fertilization (IVF) remains unclear. Here, we examined the effects of melatonin on cytoplasmic maturation and the incidence of polyspermic penetration in porcine oocytes. No statistically significant difference was observed in the rate of first polar body formation between the groups (Control, Melatonin, Melatonin + Luzindole, and Melatonin + 4-P-PDOT). Interestingly, melatonin supplementation significantly improved the cytoplasmic maturation of porcine oocytes by enhancing the normal distribution of organelles (Golgi apparatus, endoplasmic reticulum and mitochondria) and upregulating organelle-related gene expressions (P < 0.05). However, these promotional effects were counteracted by melatonin antagonists, suggesting that melatonin enhances cytoplasmic maturation through its receptors in porcine oocytes. Melatonin supplementation also significantly improved the rate of diploid and blastocyst formation after IVF by promoting the normal distribution of cortical granules (P < 0.05). In conclusion, melatonin supplementation during in vitro maturation of porcine oocyte improves fertilization efficiency and embryonic developmental competence by enhancing cytoplasmic maturation.

On the secondary promotion effect of Al and Ga on Cu/ZnO methanol synthesis catalysts

The structural and electronic effect of Al and Ga as ternary metals in Cu/ZnO catalysts for the methanol synthesis was examined. For this purpose, three zincian malachite-derived catalysts with the nominal Cu:Zn ratio of 70:30 were synthesized: an unpromoted binary catalyst (CZ) and two ternary catalysts with either 3 mol% Al (CZA) or Ga (CZG). Both Al and Ga showed a strong impact on the catalyst’s structure. Alongside the catalyst’s evolution from the co-precipitated precursors phase to the activated and reduced state, an improved microstructure and an increased BET surface area were found for the secondary promotor (Al or Ga) containing catalysts. Moreover, a sequence of chemisorption experiments allowed us to quantify and differentiate between Cusurf and Znred surface species in the activated catalysts. Considering the specific copper surface areas, DRIFTS data and catalytic results, an additional electronic promotion of Al and Ga is proposed. As demonstrated by Ga K-edge XANES, this promotion effect is related to doping of the ZnO support and enhances the reducibility of ZnO to form more Znred sites. This effect is stronger for Al leading to a more pronounced Znred overlayer on the Cu surface due to SMSI. In methanol synthesis, this results in a performance order CZA > CZG > CZ.
