To comprehensively prevent and resolve the potential risk of a "bottleneck" in the context of reverse globalization, sorting out China's potential autononious and controllable key products systematically is an important issue. The paper constructs a product space network model according to the data of 243 countries' export products fkom 1995 to 2019 and measures the product coreness based on the revealed comparative advantage of products to identift' global core products. On this basis, the close degree of grey incidence model is used to quantitatively analyze the close correlation degree of the overall revealed comparative advantage distribution of countries in the global product system. And through the analysis of the marginal contribution of revealed comparative advantage, the study also identities China's potential autonomous and contiollable key products. Among the 124 global core products in the top 10% of the coreness in 2019, the products whose revealed comparative advantage changes make a greater contribution to the distribution of China's overall revealed comparative advantage are potential autonomous and controllable key products in China. Among the top 31 kinds of core products with the top 25% contribution rate, China 's potential autonomous and conn·ollable key products are mainly distributed in the fields of mechanical mid electrical equipment, vehicles, aircraft and ships, optical and medical precision instruments with high-tech characteristics, as well as in the field of chemical products with capital-intensive characteristics.

This article collected papers published by Chinese archaeologists in Chinese and World core journals (CCJs and WCJs for short) in the past century. Based on bibliometric analysis, the general characteristics and trends of Chinese archaeology were summarized. In a macroscopic perspective, historiography-rooted archaeology focusing on historical periods and central areas of China and preferring traditional archaeological methods (mainly a culture-historical paradigm) will continue to occupy a leading position in China. Simultaneously, interdisciplinary research and internationalisation will likely continue to develop and diversify Chinese archaeology, though the speed is unknown due to the impact of the pandemic. In comparison, more attention needs to be paid to theoretical research and to publishing more results of historical archaeology in WCJs. [ABSTRACT FROM AUTHOR]

Recently, papers with multiple corresponding authors (co-correspondence) are frequently noticed in scientific journals. This is a trend that parallels a significant increase in research collaboration, but its rapidity raises concern about whether the legitimacy and value of the corresponding authorship are changing or even damaged. This study investigated how extensive and sound the trend of co-correspondence in science and engineering is. The increasing trend of co-correspondence papers was confirmed by examining SCOPUS index (www.scopus.com) for the papers published by scholars of the USA, Japan, South Korea, and China in 2008-09 and 2018-2019. The number of co-correspondence papers indeed increased in all four countries. However, the numbers varied significantly among the countries, markedly higher in South Korea and China cases, which also showed far higher numbers of the papers with a co-corresponding author who is the only member from his group. To dig into reality, South Korean scholars were surveyed with questionnaires regarding the trend of co-correspondence. Over 64% of respondents answered that they had participated in papers where multiple corresponding authors are listed, and 22% of them thought that the co-corresponding author did not play his due role and the co-corresponding authorship was exchanged between friends or given as a courtesy for various reasons. Although corresponding authorship allocation is majorly a concern for journal editors, a trend of inappropriate practices or misuse of co-corresponding authorship calls for local and global academic community awareness.

The present study is aimed toward examining the attention received by research papers through social and electronic media in business research. In recent years, altmetrics has emerged as a complementary measure of the impact of research works besides citation analysis and bibliometrics. Using the altmetric attention score (AAS) the paper is the first research of its kind to shed light on the characteristics of 100 papers receiving the highest online attention. Various predictors of online engagement with articles in business research journals having an impact factor greater than 6 are discussed. Data was collected from the Dimensions.ai database and analyzed using R statistical software. It is found that the Journal of Business Ethics contributed maximum papers with the highest AAS followed by the Journal of Business Research. Using the Kruskal-Wallis rank-sum test it was determined that AAS in business research is dependent upon article type, topics, and journal of publication. Most of the papers in high impact factor business journals have been contributed by the authors of USA, UK and China. [ABSTRACT FROM AUTHOR]

In recent years, with the rapid development of the Internet industry, the publicity effect of paperbark walnuts has been substantially increased, and the consumption and demand of paperbark walnuts have been rising, and the output of paperbark walnuts in China has also increased year by year. This paper takes the panel data of the top three prefecture-level cities in each GDP ranking of five provinces in northwest China from 2012 to 2021 as the sample and combines the DEA model with Malmquist to evaluate and analyze the logistics efficiency of paper walnuts in northwest China. It is found that the overall logistics efficiency of paperback walnuts in Northwest China has been improved in recent years, but there are still areas that need to be improved, such as the factor distribution is not reasonable enough; the logistics efficiency of paperback walnuts in Northwest China from 2012 to 2021 is in a fluctuating state; the logistics efficiency of paperback walnuts in Shaanxi Province is better than the other provinces and is in the leading position; the improvement of technological progress has a key role in the total factor productivity improvement. As a result, this paper puts forward five specific suggestions based on the research results to help accelerate the improvement of paper walnut logistics efficiency in Northwest China.

Covering the full texts of all papers published in MDPI's Remote Sensing between 2009 and 2021, in-depth scientometric analyses were conducted. Trends in publications show an increase in the overall number of papers. A relative increase in papers using SAR sensors and a relative decrease in papers using optical remote sensing can also be seen. The full-text analyses reveal distinctive styles and writing patterns for papers from different sub-fields of remote sensing and for different countries and even cities. While a slight increase in the readability of abstracts is detected over time, the overall readability of papers is decreasing. Institutional co-authorship analysis reveals the ongoing 'scientific decoupling' between China and the USA in remote sensing. Using scientometric full-text analysis, current trends and developments are revealed. [ABSTRACT FROM AUTHOR]

The paper-disc soil method is a soil algal bioassay used to assess soil water transfer in polluted soils. Although this ecotoxicological method was first established in 2016 to assess soil pollution, quantitative toxicity assessments of Cu- or Ni-treated soil and in situ or ex situ soils polluted with other heavy metals (HMs) have not been widely conducted. In this study, the paper-disc soil method was validated under different test conditions. The validated paper-disc soil method was used to quantitatively investigate the toxicity of four HMs (As, Cd, Cr, and Zn). Based on the results, the test species, initial inoculation concentration in the algal-dispersed solution, water content, light intensity, and exposure duration were proposed as Chlorococcum infusionum, 3 × 10 6 cells/mL in Bold's basal medium, 80% water-holding capacity, 4000 ± 500 lx, and 6 days, respectively. The toxicity of HMs was quantified using the validated paper-disc soil method, and the half-maximal effective concentration values for biomass were calculated as 22.49 (21.26-23.78) mg Cr/kg dry weight (dw) soil, 42.72 (38.64-47.24) mg Cd/kg dw soil, 57.79 (55.46-60.21) mg As/kg dw soil, and 183.06 (175.38-191.06) mg Zn/kg dw soil. The paper-disc soil method using the soil alga C. infusionum was validated by quantitatively evaluating the test conditions and toxicity of HMs. Our results provide important quantitative toxicity data for soil algae exposed to HMs and a basis for standardizing the paper-disc soil method using soil algae., (Copyright © 2022 Elsevier Inc.

Introduction: The Western Ontario and McMaster University osteoarthritis index (WOMAC) is the most commonly used indicator of disease-specific outcome in knee osteoarthritis for its convenience and reliability. It has two formats the paper-based WOMAC (p-WOMAC) and the electronic WOMAC (e-WOMAC). In China, the p-WOMAC has been widely used though e-WOMAC is yet untested. This study aims to test whether e-WOMAC is consistent with the p-WOMAC before and after the intervention., Methods and Analysis: A total of 70 patients from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine will be randomly assigned in two groups, named, group A and group B. This study is divided into three stages. In the first stage, patients in group A will be evaluated first by p-WOMAC and then by e-WOMAC. Patients in group B will be evaluated by e-WOMAC and then by p-WOMAC. In the second stage of the study, drug interventions will be implemented. 200 mg celecoxib will be administered orally once a day starting from the second day of enrolment for a period of 21 days. In the third stage, postintervention evaluation will be conducted after administration. Patients in group A will be evaluated first by e-WOMAC and then by p-WOMAC. Patients in group B will be evaluated first by p-WOMAC and then by e-WOMAC. In order to avoid the possible bias because of patients' potential memory, e-WOMAC and p-WOMAC will be taken for each patient at 15 min apart. The primary outcome of the study is the mean score difference in WOMAC, and the secondary outcomes are the score differences in WOMAC subscales: pain, stiffness and physical function., Ethics and Dissemination: The protocol has been approved by the Independent Review Board of SGH (approval number: 2020-814-21-01). The results of the trial will be submitted for publication in a peer-reviewed journal., Trial Registration Number: ChiCTR2100050914., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

While participation in the international division of labor has led to rapid economic development, it has also resulted in pressing environmental issues in China. In the context of "building a resource-saving and environment-friendly society" and the current sustainability requirements, research on the environmental impact of Chinese paper companies from the perspective of Environmental Information Disclosure (EID) policy and trade has not yet reached a consensus. This study constructs an analytical framework for the EID policy impact mechanism and trade on the environmental effects of the paper industry and enterprises. It explores the direct and indirect effects of EID policy and import-and-export trade on the paper industry environmental effects using the Propensity Score Matching and Difference-in-Differences (PSM-DID) model. EID positively impacts the pollution reduction of enterprises mainly through the technical effect. Export trade positively impacts the reduction of enterprises' emissions through the technology effect. However, the demand of the international market increases the pollution from the paper industries, which has a negative impact. Importing will enable enterprises to obtain greater price advantages which can alleviate and transfer the costs brought by EID. This study analyzes the impact of trade on the environmental effects of Chinese paper enterprises and identifies the impact of China's EID policy and trade on enterprises' pollution emissions. It provides a theoretical and practical foundation for the Chinese government to formulate environmental and trade policies.

There has been controversy regarding the air pollutants emitted from sources closely related to the activities of daily life in China, such as cooking, setting off fireworks, sacrificial incense and joss paper burning, and barbecue (which have been named the five missing sources – FMSs), and the extent to which they impact the outdoor air quality. To date, due to the lack of both an activity dataset and emission factors, there have been no estimations of the emission of air pollutants from FMSs. In this work, we have attempted to combine questionnaire data, various statistical data, and data on points of interest to obtain a relatively complete set of activity data. The emission factors (EFs) of carbonaceous aerosols were tested in our lab. Emission inventories of carbonaceous aerosols with a high spatial–temporal resolution for FMSs were then established, and the spatial variation trend and driving forces were discussed. From 2000 to 2018, organic carbon (OC) emissions were in the range of 4268–4919 t. OC emissions from FMSs were between 1.5 ‰ and 2.2 ‰ of the total emissions in China. Black carbon (BC), elemental carbon (EC), and brown carbon (BrC) absorption cross-section (ACS BrC) emissions from FMSs were in the ranges of 22.6–43.9 t, 213–324 t, and 14.7–35.6 Gm 2 , respectively. Their emissions tended to be concentrated in certain periods and areas. The OC emission intensities in central urban areas were 3.85–50.5 times those in rural areas (due to the high density of human activity), while the ACS BrC emissions in rural regions accounted for 63.0–79.5 % of the total emissions (resulting from uncontrolled fireworks). A mass of fireworks led to much higher ACS BrC and EC emissions on Chinese New Year's Eve, with respective values that were 1444 and 262 times their corresponding yearly averages. Significant (p<0.01) correlations between the population's income and pollutant emissions were also found: these correlations were positive (r=0.94) and negative (r=-0.94) for urban and rural regions, respectively, indicating the necessity to regulate residents' lifestyles and increase residents' income in respective urban and rural regions. This study provides firsthand data to identify emissions, variation trends, and impacting factors from the FMSs. This is helpful for modeling works on air quality, the climate effect, and human health risks during specific periods or in specific regions as well as for modifying emission control policies. The data compiled in this work can found at 10.6084/m9.figshare.19999991.v2 (Cheng et al., 2022). [ABSTRACT FROM AUTHOR]

The digital economy has become a driving force in the rapid development of the global economy and the promotion of export trade. Pivotal in its advent, the digital transformation of enterprises utilizes cloud computing, big data, artificial intelligence, and other digital technologies to provide an impetus for evolution and transformation in various industries and fields. in enhancing quality and efficiency. This has been critical for enhancing both quality and efficiency in enterprises based in the People's Republic of China. Through the available data on its listed enterprises, this paper measures their digital transformation through a textual analysis and examines how this transformation influences their export product quality. We then explore the possible mechanisms at work in this influence from the perspective of enterprise heterogeneity. The results find that: (1) Digital transformation significantly enhances the export product quality in an enterprises, and the empirical findings still hold after a series of robustness tests; (2) Further mechanism analysis reveals that the digital transformation can positively affect export product quality through the two mechanisms of process productivity (φ), the ability to produce output using fewer variable inputs, and product productivity (ξ), the ability to produce quality with fewer fixed outlays; (3) In terms of enterprise heterogeneity, the impact of digital transformation on export product quality is significant for enterprises engaged in general trade or high-tech industries and those with strong corporate governance. In terms of heterogeneity in digital transformation of enterprise and the regional digital infrastructure level, the higher the level of digital transformation and regional digital infrastructure, the greater the impact of digital transformation on export product quality. This paper has practical implications for public policies that offer vital aid to enterprises as they seek digital transformation to remain sync with the digital economy, upgrade their product quality, and drive the sustainable, high-quality, and healthy development of their nation's economy.

Introduction: The Yangtze vole (Microtus fortis) is a small herbivorous rodent that usually causes damage to crops and forests in China. Various measures were used to control their population including chemical rodenticides. However, rodenticides may cause secondary damage to the environment and the ecosystem. Therefore, the development of new rodent sterilants is urgent. Considering that some compounds of paper mulberry leaves have been verified that can inhibit the biosynthesis of sexual hormone, we aimed to explore the antifertility effect of paper mulberry leaves on M. fortis. Methods: In this study, voles were divided into three groups including a male group, a female group, and a breeding group, and paper mulberry leaves were added into basal fodder of voles maintained in laboratory, of which the proportion of leaf weight was 50%. In each group, voles were fed with mixed fodder as treatment (BP) and voles were fed with basal fodder as contrast (CK). Results and discussion: After feeding for more than 1 month, the results indicated that paper mulberry leaves attracted voles to feed, but inhibited their growth and reproduction. Since the second week, food intakes of BP have been significantly higher than CK (p< 0.05). However, weights of voles in male and female groups were 72.283 ± 7.394 g and 49.717 ± 2.278 g in the fifth week, and both were significantly reduced compared with their original weight (p< 0.05). Meanwhile, testicular volumes of male voles fed with BP were significantly smaller than CK (former: 318.000 ± 44.654 mm3, latter: 459.339 ± 108.755 mm3); the testosterone level, sperm number, and vitality of BP were obviously weaker than CK. Female uteruses and oophoron of BP grew slower, and the organ coefficients of uterus and oophoron fed BP were both significantly lower than CK (p< 0.05). The first reproduction of BP couple voles spent 45 days, while CK spent only 21 days. These results suggest that paper mulberry leaves could be the potential resource to produce sterilants to control rodent populations by delaying their sexual growth and reproduction. If it was practical, the apparent advantages of paper mulberry are that it is an abundant resource and the inhibitory effect could be effective in both male and female individuals. Our conclusion also supports the transformation of rodent management from lethal management to fertility control, which would be more ecologically friendly to agriculture and the ecosystem.

There has been controversy about the air pollutants emitted from sources closely related to people's daily life (such as cooking, fireworks burning, sacrificial incenses and joss paper burning, and barbecue, named as five missing sources, FMS) impacting the outdoor air quality to what extent. Till now, there is no emission estimation of air pollutants from FMS, as the missing of both activity dataset and emission factors. We attempted to combine the questionnaire data, various statistical data, and data of points of interest to obtain a relatively complete set of activity data. The emission factors (EFs) of carbonaceous aerosols were tested in our lab. Then, the emission inventories of carbonaceous aerosol with the high spatial-temporal resolution for FMS were established firstly, and the spatial-variation trend and driving forces were discussed. From 2000 to 2018, organic carbon (OC) increased from 4268 t to 4919 t. The OC emission from FMS was 1.48-2.18 - of its total emission in China. The emissions of black carbon, element carbon (EC), and brown carbon absorption cross-section (ACSBrC) emissions from FMS were in the ranges of 22.6-43.9 t, 213-324 t, and 14.7-35.6 Gm2, respectively. Their emissions tended to concentrate in special periods and areas. The OC emission intensities in central urban areas were 3.85-50.5 times that of rural areas due to the high density of human activities. While the ACSBrC emissions in rural regions accounted for 63.0-79.5% of the total emission result from uncontrolled fireworks burning. A mass of fireworks burning led to extremely higher ACSBrC and EC emissions on Chinese New Year's eve, as 1444 and 262 times their corresponding yearly average values. Interestingly, significant (p<0.01) correlations between human incomes and pollutant emissions were found, but they were positive (r = 0.94) and negative (r = -0.94) for urban and rural regions, indicating the necessity of regulating human lifestyle and increasing income for urban and rural peoples, respectively. This study provided the first-hand data for identifying the emissions, variation trends and impacting factors of FMS, which is helpful for modeling works on air quality, climate effect, and human health risks at specific periods or regions and for modifying their emission control policies.

Existing literature ignores to consider multiple types of pollutants when analyzing energy efficiency and its convergence. Under this background, using SuperSBM-GML model, the improved entropy method, and convergence model, this paper calculates the green total-factor energy efficiency and its evolution trend of 35 China's industrial sub-sectors considering multiple pollutants, and analyzes its convergence. The results indicate that the average score of industrial green total-factor energy efficiency is low, and there are significant differences among sub-sectors: "Utilization of waste resources" is the highest, while "Manufacture of paper and paper products" is the lowest. The green total-factor energy efficiency shows an overall upward trend from 2006 to 2021, the main driving force comes from technological progress, but numerous sub-sectors have not sufficiently caught up with existing cutting-edge technologies. Specifically, the growth rate of green total-factor energy efficiency in high-energy-consumption sub-sectors is higher than low-to-medium-energy-consumption sub-sectors. There are both σ-convergence and β-convergence in low-to-medium-energy-consumption group, indicating that development of sub-sectors is stable and outstanding. Nevertheless, the high-energy-consumption group only exhibits conditional β-convergence, revealing an imbalance in energy efficiency development. Consequently, formulating the benchmark level of energy efficiency and developing energy efficiency "leader" system are suggested for low-to-medium and high-energy-consumption sub-sectors, respectively.

The Tibetan Plateau works as an important environmental and ecological barrier for the Asian continent. The researches on Tibetan environment and ecology are becoming extensive, but there is no systematic summary of research hotspots and trends in this field. Here, we analyzed 9180 publications retrieved from the WOS and CNKI during 2000 ~ 2020. The characteristics of publication, keywords with a 5-year interval and co-occurrence analysis were carried out so as to reveal the evolution and development trends of topics. The results show that articles increase dramatically since 2012. Except for common concerns like evolution, climate change, and precipitation, diversity was been studied more by Chinese scholars, while the USA, Germany, UK, and Australia researchers focused more on adaptability, basin western Tibet, lake, barley, and ore-related themes, respectively. Besides, China closely collaborated with the USA, Australia, and Germany in topics of evolution, climate change and degradation, precipitation, and diversity. The institutions located in Chinese different economic regions focused on different research keywords, such as vegetation, growth, trace elements, and geochemistry. The CAS contributed the most articles with 4254, showed advantages both in quantity and quality. Few articles were published by researchers affiliated to Free University of Berlin but with higher citations. It is the only one institute outside of China in the top 20. Main research hotspots include climate change, geology, and diversity. In future researches, ecological management and rehabilitation of mining area and tailings ponds, waste disposal, and changes of soil and water quality are worthy of attention and funding., (© 2021.

Objective: The aim of this study was to explore the geographic distribution and number of papers published in international and Science Citation Index (SCI)-indexed cytology journals based on their country of origin., Materials and Methods: A country-based geographic analysis of studies published over a 5.5-year period from January 2016 to June 2021 in 5 cytopathology journals indexed as SCI and SCI-E with an impact factor higher than 1 (Cancer Cytopathology, Cytopathology, Diagnostic Cytopathology, Acta Cytologica, and CytoJournal) and papers categorized as "original" and "other" was performed., Results: A total of 3,063 papers were found, with 1,466 (47.8%) categorized as "original" papers and 1,597 (52.1%) designated as "other" papers. These papers were submitted from 62 different countries. The five countries with the greatest number of papers were the USA (38.4%), India (16.8%), Japan (7.4%), Italy (5.5%), and Brazil (3.1%). A general subgroup analysis was also performed on the original studies without a country breakdown. Cytomorphological, cytomorphological-immunohistochemical, and molecular assessments compose 38.5%, 45.7%, and 15% of the subgroups, respectively., Conclusion: The number of academic papers originating from developing countries in the field of cytopathology has increased in recent years. Although most scientific papers are produced in developed countries, the rate in these countries is much lower than that in some developing countries as the rate of academic growth in developed countries has stabilized. Despite the widespread and sophisticated implementation of cytology in daily practice in Western European countries outside the UK, such as Germany and the Netherlands, and in Scandinavian countries and other developed countries, such as Australia and Canada, these countries rank in the middle to lower end of countries producing cytology papers. Meanwhile, there has been an increase in the number of cytology papers published by authors from Southern European countries, such as Italy (ranked 4th) and Spain (ranked 6th), and Turkey (ranked 8th). There is a remarkable increase in cytology papers originating from Asia, particularly India, Japan, and China., Summary: We aimed to present a basic survey of the geographic distribution of manuscript submissions to high-impact cytopathology journals and to point out emerging trends in cytology utilization and basic research. However, our results show that the landscape of cytology is changing and suggest geographic regions that are ripe for the production of novel "points of view" and new research findings., (© 2022 S.

Objectives: Patient and public involvement (PPI) in health research is required by some funders and publications but we know little about how common it is. In this study we estimated the frequency of PPI inclusion in health research papers and analysed how it varied in relation to research topics, methods, funding sources and geographical regions., Design: Cross-sectional., Methods: Our sample consisted of 3000 research papers published in 2020 in a general health-research journal ( BMJ Open ) that requires a statement on whether studies included PPI. We classified each paper as 'included PPI' or 'did not include PPI' and analysed the association of this classification with location (country or region of the world), methods used, research topic (journal section) and funding source. We used adjusted regression models to estimate incident rate ratios of PPI inclusion in relation to these differences., Results: 618 (20.6%) of the papers in our sample included PPI. The proportion of papers including PPI varied in relation to location (from 44.5% (95% CI 40.8% to 48.5%) in papers from the UK to 3.4% (95% CI 1.5% to 5.3%) in papers from China), method (from 38.6% (95% CI 27.1% to 50.1%) of mixed-methods papers to 5.3% (95% CI -1.9% to 12.5%) of simulation papers), topic (from 36.9% (95% CI 29.1% to 44.7%) of papers on mental health to 3.4% (95% CI -1.3% to 8.2%) of papers on medical education and training, and funding source (from 57.2% (95% CI 51.8% to 62.6%) in papers that received funding from the UK's National Institute for Health Research to 3.4% (95% CI 0.7% to 6.0%) in papers that received funding from a Chinese state funder)., Conclusions: Most research papers in our sample did not include PPI and PPI inclusion varied widely in relation to location, methods, topic and funding source., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Nitrite is one of the most common carcinogens in daily food. Its simple, rapid, inexpensive, and in-field measurement is important for food safety, based on the requirements of the standard from Codex Alimentarius Commission and China. Using polyacrylonitrile (PAN) and thin layer silica gel (SG), p-aminophenylcyclic acid (SA) and naphthalene ethylenediamine hydrochloride (NEH), as carriers and chromogenic agents, respectively, PAN-NSS as nitrite color sensor is proposed. After fixing and protecting of SA and NEH with layer-upon-layer PAN, the validity period of the test paper can be prolonged from 7 days to more than 30 days. The reproducibility of PAN-NSS preparation is ensured by electrospinning. Combined with PAN-NSS, deep convolutional neural network (DCNN) and APP as a visual monitoring platform, which has the functions of rapid sampling, data processing and transmission, intuitive feedback, etc., and provides a fully integrated detection system for field detection., (Copyright © 2021 Elsevier Ltd.

The Guidelines on Building a Market-Oriented Green Technology Innovation System, which was released by China in 2019, has become a powerful signal to guide the development of green technology innovation (GTI). In the current digital strategy of China, the public media has become a key factor for promoting the transparency of enterprise environmental information. This paper measures the GTI efficiency of the listed paper enterprises in China as well as incorporating media attention into the research framework to explore the influencing factors of GTI of the listed paper enterprises in China during the digital economy era. The results showed that a positive media report had a positive impact on GTI and has become a new driving factor in promoting sustainable production in the digital era. Government support and openness also have a positive impact on GTI. However, negative media reports, environmental regulations, and technological innovation abilities have an inhibitory effect on the GTI efficiency of paper making enterprises. [ABSTRACT FROM AUTHOR]

With the increasing frequency of scientific cooperation, research on the impact of scientific cooperation on scholars' scientific performance has become a hot topic in academic research. This paper mainly uses quantitative research methods such as bibliometrics and social network analysis to analyze the correlation between degree centrality, L-index, and scientific performance of the Chinese author of Physical Education and Training Science and draws the following conclusions: (1) degree centrality is positively correlated with the number of papers, average citations per paper, and H-index and (2) L-index is positively correlated with the number of papers, average citations per paper, and H-index. Unlike previous studies on scientific collaboration networks and scholars' performance that focused on traditional network characteristics indicators, this study introduces a new network characteristics indicator, L-index, through which the degree of collaboration between authors and other important authors in the research field can be better assessed, which also provides a new direction for research related to research collaboration networks and scholars' performance; at the same time, it also provides a theoretical basis for subsequent research on the utility of scientific collaboration, a reference for the assessment of the research performance of scholars in other disciplines, and a theoretical reference for more scientific and comprehensive prediction of scholars' research performance in the future.

As a traditional energy and carbon intensive sector, it becomes imperative for the global paper industry to realize green development. This paper aims to provide guidance for the green transformation of global paper industry by evaluating the global paper industry green development level in a systematic and dynamic way. This paper employs text-mining method to develop paper industry green development evaluation indicator system and adopts market-extended LCA model and entropy-TOPSIS method to calculate the paper industry green development level of 48 countries/regions. The results show that during 2000–2030 the paper industry green development level of developing countries improves faster than developed countries, where those of developing and developed countries increase from 0.3369 to 0.3938 and from 0.5120 to 0.5517 respectively and the gap between them narrows from 0.1751 to 0.1579. The comparative analysis reveals that the paper industries of developed and developing countries are in different green development stages. Developing countries, represented by China, improve greatly in economic and social dimensions, but decline seriously in ecological dimension due to enlarging resource consumption and environmental damages. On the contrary, developed countries tend to saturate in economic and social dimensions and have been improving fast in ecological dimension, gradually realizing the decoupling of industrial economic development and environmental damages. To further promote the global paper industry green development, developing countries should focus on promoting the coordinated development between economic growth and environment protection and developed countries should play a leading role in the global green transformation by promoting optimal allocation of resources and cross-regional communications of green technologies. • A paper industry green development indicator system is developed based on text mining. • A global paper industry green development model is built with market-extended LCA. • Complex interactions among the indicators are internalized in the evaluation. • A spatial-temporal analysis is performed on global paper industry green development level.

With growing internationalism, there is a shift in research patterns in developing countries, especially China and India, generating vital and contemporary research areas that are beginning to challenge the existing Western‐dominated research literature in social sciences. Yet, many of the new ideas within conceptual papers by the social sciences are not empirically validated, let alone operationalized. This is where the group concept mapping method can play a role in bridging the gap between phenomenal conceptualization and having an empirically valid model that can then be operationalized. The group concept mapping process involves five steps: create statements, sort statements, run multidimensional scaling (MDS) of sorted units, run cluster analysis, and label the clusters. This approach allows for the collective thoughts of a pre‐defined group to be collected and organized into a tangible output with academic rigor. This paper offers an overview of the group concept mapping methodology, discussing the processes of the method, how the method can be utilized fully within the business and broader social science context, and the strengths, weaknesses, and practical implications of group concept mapping.

With the sustained economic growth, the importance of family finance has become increasingly prominent. In this research, the papers collected by Chinese National Knowledge Infrastructure (CNKI) and Web of Science (WOS) were visually analyzed via CiteSpace software, and a knowledge map for the field of family finance was constructed, which displayed the current situation, hotspots, and trends of family finance research from multiple angles in an all-round way. The results show that the number of published Chinese and English papers is increasing year by year, among which English papers are mainly contributed by American scholars, with relatively little cooperation and exchange between countries. In Chinese literature, the cooperation between authors and institutions is also limited. At present, the research in the field of family finance is ushering in a stage of rapid development, and the research hotspots mainly focus on financial literacy, financial knowledge, risk finance, and inclusive finance. Given this, the future research should focus on the cooperation among authors, institutions, and disciplines, and meanwhile, increase in-depth research on digital finance, and digital divide. These efforts will promote the further development of research in the field of family finance in China. [ABSTRACT FROM AUTHOR]

In order to prompt the appearance of the shrimp color, sodium metabisulfite is frequently added in shrimp processing, which is, however, prohibited in China and many other countries. This study aimed to establish a surface-enhanced Raman spectroscopy (SERS) method for screening sodium metabisulfite residues on shrimp surfaces, in a non-destructive manner. The analysis was carried out using a portable Raman spectrometer jointly with copy paper loaded with silver nanoparticles as the substrate material. The SERS response of sodium metabisulfite gives two fingerprint peaks at 620 (strong) and 927 (medium) cm−1, respectively. This enabled unambiguous confirmation of the targeted chemical. The sensitivity of the SERS detection method was determined to be 0.1 mg/mL, which was equal to residual sodium metabisulfite on the shrimp surface at 0.31 mg/kg. The quantitative relationship between the 620 cm−1 peak intensities and the concentrations of sodium metabisulfite was established. The linear fitting equation was y = 2375x + 8714 with R2 = 0.985. Reaching an ideal balance in simplicity, sensitivity, and selectivity, this study demonstrates that the proposed method is ideally suitable for in-site and non-destructive screening of sodium metabisulfite residues in seafood.

Objectives: This study aimed to elucidate the connection between osteoclastic forkhead transcription factor O1 (FoxO1) and periodontitis and explore the underlying mechanism by which FoxO1 knockdown regulates osteoclast formation. Materials and Methods: A conventional ligature‐induced periodontitis model was constructed to reveal the alterations in the proportion of osteoclastic FoxO1 in periodontitis via immunofluorescence staining. Additionally, RNA sequencing (RNA‐seq) was performed to explore the underlying mechanisms of FoxO1 knockdown‐mediated osteoclastogenesis, followed by western blotting, quantitative polymerase chain reaction, and enzyme‐linked immunosorbent assay. Results: FoxO1+ osteoclasts were enriched in the alveolar bone in experimental periodontitis. Moreover, FoxO1 knockdown led to impaired osteoclastogenesis with low expression of osteoclast differentiation‐related genes, accompanied by an insufficient osteoclast maturation phenotype. Mechanistically, RNA‐seq revealed that the nuclear factor kappa B (NF‐κB) and nucleotide‐binding oligomerization domain‐like receptor family pyrin domain containing 3 (NLRP3) inflammasome signaling pathways were inhibited in FoxO1‐knockdown osteoclasts. Consistent with this, MCC950, an effective inhibitor of the NLRP3 inflammasome, substantially attenuated osteoclast formation. Conclusions: FoxO1 knockdown contributed to the inhibition of osteoclastogenesis by effectively suppressing NF‐κB signaling and NLRP3 inflammasome activation. This prospective study reveals the role of FoxO1 in mediating osteoclastogenesis and provides a viable therapeutic target for periodontitis treatment. [ABSTRACT FROM AUTHOR]

Paper‐based composite packages, which have been widely used for beverage in modern daily life, are featured of nutrition preservation and convenience. However, it is also causing environmental problems in urban areas because of the low recycling rate. The introduction of extended producer responsibility (EPR) is helpful to improving the recycling rate of beverage paper‐based composite packaging by extending the producer's environmental‐protecting responsibility for the product from its production to its end‐of‐life treatment. To find out the optimal strategy of applying the EPR system for beverage paper‐based composite packaging, this paper is conducted based on the basic framework of the EPR system, combined with the specific requirements of the EPR System Implementation Plan promulgated by China and the Implementation Plan of the EPR System for Beverage Paper‐Based Composite Packaging. An evaluation index system for beverage paper‐based composite packaging manufacturers is constructed to perform the EPR system, including three management‐level indicators, 10 standard‐level indicators and 42 programme‐level indicators. A comprehensive evaluation method is introduced to help the producers to fulfill the extended producer responsibility. Results suggest that beverage paper‐based composite packaging producers should first fulfill the responsibility in information disclosure, ecological design and use of recycled materials.

Objectives: To examine the characteristics, methodological and reporting quality of systematic reviews and meta-analyses in social science journals in China., Study Design and Setting: The Chinese Social Sciences Citation Index (CSSCI) databases were searched for systematic reviews and meta-analysis published between January 2000 and December 2019. We randomly selected 200 articles from the 401 identified in our search. The Assessing the Methodological Quality of Systematic Reviews (AMSTAR) and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklists were used to assess the methodological and reporting quality, respectively., Results: The 200 articles we selected covered a wide range of research fields in 9 disciplines, most of which belonged to management, education and psychology. The mean AMSTAR score and PRISMA score was 8.99 ± 3.36 points and 14.74 ± 3.96 points, respectively. These findings indicated that the quality of the systematic reviews was below the average level. Meanwhile, year of publication was related to both methodological quality (P = 0.001) and reporting quality (P < 0.01)., Conclusion: Although many systematic reviews and meta-analysis have been published in top Chinese journals, the methodological and reporting quality is troubling. Thus, the most urgent task is to increase the standard of systematic reviews and meta-analysis of every discipline rather than continuing to publish them in great quantity., (Copyright © 2021.

Objective: This study collected randomized controlled trials (RCTs) published in the social sciences in China and assessed their risk of bias and reporting quality., Study Design and Setting: Three databases were systematically searched for publications from January 2000 to June 2020 for RCTs in the social sciences published by Chinese researchers. The risk of bias was assessed using the Cochrane Collaboration Risk of Bias Tool, and reporting quality was assessed using the Consolidated Standards of Reporting Trials for Social and Psychological Interventions (CONSORT-SPI)., Results: A total of 316 RCTs were identified, including 204 articles in English and 112 articles in Chinese. The most frequently researched interventions focused on education (33.9%), and the most frequently studied population were students (32.9%). Eighty-seven percent of RCTs had intermediate reporting quality. Twenty-four of the 43 CONSORT-SPI sub-items had a compliance rate of less than 50%. Most RCTs had an unclear risk of bias for blinding outcome assessors (84.5%), blinding participants and personnel (82.9%), allocation concealment (73.1%), and random sequence generation (68.0%). A low proportion of CONSORT-SPI items were reported and, high proportion of the papers had unclear risk of bias., Conclusion: The quality and reporting of RCTs in the social sciences needs improvement in China, especially for reporting methods and results. Most studies had an unclear risk of bias as they lacked important methodological information., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objectives: To present the history and potential for development of evidence-based (EB) social work in China., Study Design and Setting: The conception and methodology of EB social work is a potential strategy to support high quality development of social work in China. This article documents and analyzes the progress of EB social work in China. We focus on current research, reasons, challenges, and strategies., Results: EB social work started late in China. The number of EB social work literature and systematic reviews has increased since 2004. The development of EB social work has been uneven nationally with few practitioners and decision makers involved. However, more and more social work researchers received training in evidence-based practice through national workshops and conferences., Conclusion: EB social work faced various challenges, but there are now more opportunities for EB social work development in China. Researchers, practitioners, managers and decision makers are encouraged to work together to establish a thorough methodological system and use existing evidence as much as possible when carrying out social work programs and services., (Copyright © 2021 Elsevier Inc.

This paper conceptualises digital displacement as both a way through which the digital, dynamic and fragile spatialities of contentious politics can be examined and as a geographic critique of censorship. Digital displacement, understood here as the act of removing users from the digital places and spaces they wish to remain in and use, often through the act of deletion, is conceptualised through the digital displacement of two contentious political groups that attempted to contest the forced eviction of migrants from Beijing in 2017; hashtag focused #BeijingSurgery# and instant messaging group using BeijingTogether. Explored through participant observation, interviews and playful digital exploration, this paper examines the spatialities that made multiple digital displacements possible and the activist spatialities that emerged during and post‐displacement. In exploring this, I develop a flexible vocabulary around digital place, space, scale, territory and mobility to analyse the practices of digital displacement, to understand the socio‐spatial positionality of activists involved in digitally centred contentious politics and to contextualise their territorial positionality within Chinese digital territory and global digital territories. Through the examination of #BeijingSurgery# and BeijingTogether, the article highlights: the importance of digital territorial positionality for both activists and the digital places and spaces used for contentious politics; that within systems of digital spatial governance, deletion and displacement can be effective strategies of repressive governance with wide‐ranging displacement effects; and that while digital displacement is not necessarily the ending point of contentious politics, the re‐production of activist spatialities is more difficult when the authority being protested against governs the digital territory used for protest. This paper conceptualises digital displacement as: a way through which the digital, dynamic and fragile spatialities of contentious politics can be examined; a way to understand China's digital territorialization project; and as a geographic critique of censorship. Digital displacement is conceptualised through the ethnographic research conducted in Beijing and examines efforts to contest the forced eviction of migrants from Beijing in 2017.

The impact of COVID‐19 has underlined the need for reliable information to guide clinical practice and policy. This urgency has to be balanced against disruption to journal handling capacity and the continued need to ensure scientific rigour. We examined the reporting quality of highly disseminated COVID‐19 research papers using a bibliometric analysis examining reporting quality and risk of bias (RoB) amongst 250 top scoring Altmetric Attention Score (AAS) COVID‐19 research papers between January and April 2020. Method‐specific RoB tools were used to assess quality. After exclusions, 84 studies from 44 journals were included. Forty‐three (51%) were case series/studies, and only one was an randomized controlled trial. Most authors were from institutions based in China (n = 44, 52%). The median AAS and impact factor was 2015 (interquartile range [IQR] 1,105–4,051.5) and 12.8 (IQR 5–44.2) respectively. Nine studies (11%) utilized a formal reporting framework, 62 (74%) included a funding statement, and 41 (49%) were at high RoB. This review of the most widely disseminated COVID‐19 studies highlights a preponderance of low‐quality case series with few research papers adhering to good standards of reporting. It emphasizes the need for cautious interpretation of research and the increasingly vital responsibility that journals have in ensuring high‐quality publications. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to systematically review the methodological and reporting quality of clinical practice guidelines (CPGs) developed in China and published in medical journals between 2014 and 2018., Study Design and Setting: We conducted a comprehensive search in multiple databases: MEDLINE (via PubMed), Embase, CBM (China Biology Medicine), CNKI (China National Knowledge Infrastructure) and Wanfang Data. We included all clinical practice guidelines developed in China between 2014 and 2018. The AGREE II tool and the RIGHT checklist were used to appraise the methodological quality and reporting quality of the included guidelines, respectively., Results: We identified 17,188 records, and included finally 573 CPGs. Most (n=507, 88.5%) were published in Chinese, and 508 (88.7%) were about Western medicine. Only 62 (10.8%) of the guidelines used the GRADE approach. The mean overall score of methodological quality over all guidelines was 19.4%, and the mean scores for the AGREE II domains were 28.6% (Scope and purpose), 17.0% (Stakeholder involvement), 11.7% (Rigor of development), 32.2% (Clarity of presentation), 14.2% (Applicability) and 12.8% (Editorial independence). The mean overall score for reporting quality over all guidelines was 30.2%, with the following mean scores for each RIGHT domain: 55.6% (Basic information), 43.8% (Background), 14.5% (Evidence), 29.2% (Recommendations), 10.7% (Review and quality assurance), 12.6% (Funding and declaration of interest) and 8.4% (Other information). Subgroup analyses found that both the methodological and reporting quality were generally higher among CPGs that used evidence grading systems or reported receiving funding., Conclusion: Both the methodological quality and the reporting quality of CPGs developed in China have improved over time, but are still below the international average., (Copyright © 2021 Elsevier Inc.

Objective: To assess the methodological and reporting quality of Chinese- and English -language systematic reviews and meta-analyses (SRs/MAs) published by Chinese authors between 2016 and 2018., Study Design and Setting: We searched MEDLINE and Chinese Science Citation Database (CSCD) for SRs/MAs led by Chinese authors published between 2016 and 2018. We used random sampling to select 10% of the eligible SRs/MAs published in each year from CSCD, and then matched the same number of SRs/MAs in MEDLINE. Reporting quality was evaluated using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and methodological quality using the Assessment of Multiple Systematic Reviews (AMSTAR-2) tool. Stratified analyses were conducted to compare the differences of quality between Chinese- and English language SRs/MAs., Results: We identified 336 SRs/MAs (168 in Chinese and 168 in English). The reporting quality in Chinese-language SRs/MAs was slightly lower than English-language SRs/MAs (mean PRISMA scores: 20.58 vs. 21.71 in 2016, 19.87 vs. 21.24 in 2017, and 21.29 vs. 22.38 in 2018). Less than half of both Chinese- and English-language SRs/MAs complied with item 5 (protocol and registration), item 7 (information sources), item 8 (search) and item 27 (funding)). The methodological quality in Chinese -language SRs/MAs was also slightly lower than English -language SRs/MAs (mean AMSTAR-2 scores: 8.07 vs. 9.36 in 2016; 9.21 vs. 10.26 in 2017; 8.86 vs. 9.28 in 2018). Three items (item 2: established a protocol; item 4: use a comprehensive literature search; and item 10: report the sources of funding) were adhered to by less than 10% of both Chinese- and English -language SRs/MAs. Only one (0.6%) Chinese-language SRs/MA and nine (5.4%) English-language SRs/MAs were rated as high methodological quality., Conclusion: The reporting and methodological quality of English-language SRs/MAs conducted by authors from China between 2016 and 2018 were slightly better than those of Chinese -language SRs/MAs., (Copyright © 2021.
