- Abstract
Recent world developments have created an opportune time for nations to vigorously pursue a policy of converting the huge portion of their economies that traditionally have been devoted to military expenditures to more socially productive uses. This paper outlines a strategy for such a conversion, and discusses the issues that must be confronted in such a process. Specific aspects of conversion include: (1) misconceptions about lessening military spending; (2) building a conversion coalition; (3) the paths forged by China and the Soviet Union; (4) upheaval in Eastern Europe; and (5) grassroots initiatives in the West. It is concluded that the gathering pressure for disarmament suggests that conversion will be a topic gaining importance during the 1990's. A number of statistical tables, charts, and maps appear throughout this paper, and 127 endnotes are provided. (DB)

- Abstract
With the aim of tailoring future programming decisions to local conditions and concerns, an ethnographic study was commissioned to examine childrearing practices in a small middle income village in Hebei Province, China. The research was designed to learn about the concerns and goals of child care providers, and about the strategic thinking and activities that derived from these goals and concerns. This report details the study of 10 children between the ages 1 and 3 and their caregivers, typically parents or grandparents, who were observed over a 12-month period as they went about their everyday routines. Additional information was obtained through conversations with caregivers. The research was conducted in three stages, each stage during a different agricultural season. Section 1 of the report summarizes the child care arrangements for each of the children studied, showing that arrangements varied by family, and frequently changed throughout the year to accommodate parental employment and other circumstances. Section 2 of the report describes adults' practices and expectations with respect to children's health and hygiene, the various activities comprising a child's day, what adults endeavor to teach children, and children's relationships with adults. The topics covered in this section of the report address the key areas of concern articulated by childcare providers in the course of the research: (1) child health, hygiene, and the body; (2) children's activities, including toys, books, television, drawing and writing, visiting friends, and visiting relatives; (3) purposeful teaching, including names, personal information, songs and poems, counting, and teaching styles; and (4) behavior toward adults, including obedience, addressing adults, and hosting adult guests.

- Abstract
In this paper, we examine the effect of computer-assisted learning on students' long-term development. We explore the implementation of the "largest ed-tech intervention in the world to date," which connected China's best teachers to more than 100 million rural students through satellite internet. We find evidence that exposure to the program improved students' academic achievement, labor performance, and computer usage. We observe these effects up to ten years after program implementation. These findings indicate that education technology can have long-lasting positive effects on a variety of outcomes and can be effective in reducing the rural--urban education gap.

- Abstract
EdTech which includes online education, computer assisted learning (CAL), and remote instruction was expanding rapidly even before the current full-scale substitution for in-person learning at all levels of education around the world because of the coronavirus pandemic. Studies of CAL interventions have consistently found large positive effects, bolstering arguments for the widespread use of EdTech. However CAL programs, often held after school, provide not only computer-based instruction, but often additional non-technology based inputs such as more time on learning and instructional support by facilitators. In this paper, we develop a theoretical model to carefully explore the possible channels by which CAL programs might affect academic outcomes among schoolchildren. We isolate and test the technology-based effects of CAL and additional parameters from the theoretical model, by designing a novel multi-treatment field experiment with more than four thousand schoolchildren in rural China. Although we find evidence of positive overall CAL program effects on academic outcomes, when we isolate the technology-based effect of CAL (over and above traditional pencil-and-paper learning) we generally find small to null effects. Our empirical results suggest that, at times, the "Tech" in EdTech may have relatively small effects on academic outcomes, which has important implications for the continued, rapid expansion of technologies such as CAL throughout the world.

Natural yellow plant dyes and traditional medicines were used widely on historical papers in ancient China for religious reasons and conservation considerations. This study aims to evaluate some traditional yellow botanical sources of dyes that contain different chemical colorant compositions in order to understand their effects on the properties of traditional handmade paper. The physical and chemical changes in paper specimens treated with plant dyes were studied by examining properties such as the color, pH, thermogravimetric (TG) characteristics, tensile strength, folding endurance and microstructure by scanning electron microscopy (SEM). The results indicated that different colorants had different toning effects and that the main components, including carboxyl and ketone groups, could affect the paper stability at high temperatures. The results also revealed that the mechanical properties of paper specimens were improved after treatment with plant dyes. The significant improvements in the tensile strength and folding endurance and the slightly higher decomposition temperature of Amur cork tree-dyed paper could be ascribed to the strong interaction between the colorants' main components and the fibers. The scientific evaluation of the property changes is therefore valuable information for weighing the advantages and disadvantages of the various yellow toning materials for paper conservation treatment.

159. 'Publish SCI Papers or No Degree': Practices of Chinese Doctoral Supervisors in Response to the Publication Pressure on Science Students
- Author

Li, Yongyan
- Abstract
Publishing English papers in journals listed in Science Citation Index (SCI) has become a requirement for degree conferment for doctoral science students at many universities in China. The publication requirement engenders high pressure for doctoral students and their supervisors and shapes the politics of the relationship between the two parties. This is illustrated in the present paper which reports a study conducted at a prestigious university in east China. Focusing on the case of a research group in biochemistry led by an expert writer (the supervisor), the study aimed to find out, from the supervisor's perspective, what revising papers for the students means to him, and what the students learn as a result of their papers being revised. It is shown that the students depend on the supervisor to meet the publication requirement, and the supervisor believes an average student cannot write a publishable paper. The paper discusses the disempowering effect of the publication requirement, and concludes that there is a role for a course on academic English writing, and that the focus on "publishing SCI papers or no degree" should be shifted at the policy level and long-term planning should go into the training of EAP-qualified language professionals.

Publications in Renal Failure in Science Citation Index Expanded (SCI-EXPANDED) between 1992 and 2021 were analyzed. Six publication indicators: total, independent, collaborative, first author, corresponding author, and single author publications as well as their related citation indicators, were used to compare performances of countries, institutes, and authors. Comparison of the highly cited papers and journal's impact factor (IF) contributors was discussed. In addition, the main research topics in the journal were presented. Results show that China published the most total articles and reviews, as well as the first-author papers and corresponding-author papers in the journal. The Chang Gung Memorial Hospital in Taiwan ranked the top in five publication indicators: total, single-institution, inter-institutionally collaborative, first author, and corresponding-author papers. A low percentage of productive authors emerged as a journal IF contributor. Similarly, only a limited relationship between highly cited papers and IF contributing papers was found. Publications related to hemodialysis, chronic kidney disease, and acute kidney injury were the most popular topic, while meta-analysis was new focus in the last decade in the journal.

- Abstract
A burgeoning literature has documented the importance of elite colleges. Yet, little is known about access to elite education and its labor market implications in China, a country that produces one in every five college graduates in the world. College admission in China is governed by a single exam--the national college entrance exam, and the government sets admission cutoff scores for elite colleges. We examine the impacts of scoring above the elite-tier cutoff on a student's access to elite colleges and wage outcomes after graduation, using the discontinuity around the cutoff score. By employing hand-collected survey data, we find that scoring above the cutoff not only increases the chance of entering an elite college but also raises a young person's first-job wages after graduation. We also find that those just above the cutoff have peers with higher scores and better social networks than those below the cutoff, but it is less clear whether the two groups use their time differently in college.

In China, Xuan paper has been the paper of choice as artwork support and for conservation, for several centuries. However, little is known about its material properties, especially given the many grades of sized and unsized Xuan paper. In addition, there is a lack of information on its degradation. In this research, a selection of contemporary unsized Xuan papers was investigated, representing diverse raw materials. Seven out of twelve contemporary unsized Xuan papers were determined to be approximately neutral and contain > 2% alkaline reserve, indicating good durability. Viscometry was used to determine the degree of polymerisation (DP) as none of the samples gave significant reactions to the phloroglucinol spot test. The average DP of ten contemporary unsized Xuan papers is ~ 1700, excluding two papers that have presumably been sun-bleached, and that exhibit significantly lower DP. Using X-ray fluorescence, it can be demonstrated that Ca and Si are the dominant elements and interestingly, Ca content is directly correlated with ash content and with alkaline reserve. Accelerated degradation was performed at two sets of environmental conditions, i.e. 90 °C, 30% RH and 60 °C, 70% RH, and the established degradation rates agreed with the Collections Demography model of paper degradation meaning that degradation of Xuan papers proceeds in the same way as other types of paper. This research gives fundamental insights into contemporary unsized Xuan papers, which exhibit good stability during accelerated degradation despite the low starting DP in the context of the samples used in this study. Our findings may inform methods of Xuan paper production, selection of Xuan paper for conservation purposes, as well as preventive conservation of Xuan paper-based artefacts. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Personalised medicine (PM) has been fostered by technological and medical advances, but all stakeholders, including healthcare professionals, citizens and policy makers, should achieve adequate health literacy to promote PM implementation. The "Integrating China in the International Consortium for Personalised Medicine" (IC2PerMed) project, funded by the International Consortium for Personalised Medicine, focuses on this issue by highlighting the need to educate healthcare professionals and empower citizens. Within the aforementioned project, building on a mapping of European and Chinese policies in PM, experts in the field of PM participated in an online workshop and a following two-round Delphi survey, in order to identify the priority areas of intervention for healthcare professionals' education and curricula, engagement and empowerment of citizens and patients., Results: Nine experts completed the survey and reached a consensus on seventeen priorities: seven were related to health professionals' education and curricula, whereas ten on citizen and patients' awareness and empowerment., Conclusion: These priorities emphasized the importance of education and health literacy, multidisciplinary and international collaboration, public trust, and consideration of ethical, legal, and social issues. The present experience highlights the relevance of the involvement of stakeholders in informing decision-makers, developing appropriate national plans, strategies, and policies, and ensuring the adequate implementation of PM in health systems., (© 2023.

Corrugating medium was made from the solid waste of bamboo paper sludge and old corrugated container (OCC) pulp. The medium also incorporated additions of anion polyacrylamide as a retention agent and cationic starch as a strengthening agent. The estimated molecular mass of anion polyacrylamide, the addition level of anionic polyacrylamide, and the addition level of cationic starch were optimally designed using singlefactor analysis. On this premise, the optimum addition level of the solid waste of bamboo paper sludge was found. The best process conditions for the corrugating medium included a base weight of 120 g/m
-2 , 10 wt.% bamboo paper sludge solid waste, 0.3 wt.% APAM (Estimated molecular mass of 600 × 104 Daltons), and 1.5 wt.% cationic starch. The apparent density, breaking length, and ring crush index were 0.53 g/cm-3 , 2.51 km, and 7.48 N/mg-1 , respectively, under the best process conditions. This finding could help satisfy the demand for materials used for making the corrugating medium and could support the full utilization of the solid waste of bamboo paper sludge to achieve higher value.

- Abstract
Despite strong demand for attending high schools with better peers, there is mixed evidence on whether doing so improves academic outcomes. We estimate the cognitive returns to high school quality using administrative data on a high-stakes college entrance exam in China. To overcome selection bias, we use a regression discontinuity design that compares applicants barely above and below high school admission thresholds. Results indicate that while peer quality improves significantly across all sets of admission cutoffs, the only increase in performance occurs from attending Tier I high schools. Further evidence suggests that the returns to high school quality are driven by teacher quality, rather than peer quality or class size.

- Abstract
A study is reported of the performance and attainment of 32 students from overseas studying elementary Chinese as a foreign language (CFL) in a Chinese university. With an AB-BA design, they were asked to use two forms of writing media to present two essays: one a word-processed essay entitled "My Favourite Female" and the other a conventional hand-written essay entitled "My Favourite Male". The essays were marked by experienced Chinese language experts and the learners' impression of using each type of writing medium was gathered via questionnaires and interviews. Inferential statistics showed that the students performed significantly better when using a word-processor, and they thought that completing writing tasks using pencil-and-paper and word-processors were markedly different. Most of them felt that their work was more professional when produced on a word-processor. A small number of students considered that writing by hand in Chinese was aesthetically pleasing, but they appreciated the convenience of writing in words spelled and written correctly by the computer. Inter-marker consistency was more homogeneous for essays written on the computer. In conclusion, word-processors are suggested as the preferred writing medium for beginning learners of CFL.

- Abstract
Using CiteSpace to draw a keyword co-occurrence knowledge map for 1,048 research papers on the quality of higher education from 2000 to 2014 in the Chinese Social Sciences Citation Index database, we found that over the past 15 years, research on the quality of Chinese higher education was clearly oriented toward policies, and a good interactive relationship formed between research and policy. Looking at research topics, apart from macrodiscussions of the spirit of several educational reforms, the relevant topics are mainly focused on higher education quality issues in the massification stage, issues of higher education academic management, issues of student cultivation, and issues of ensuring and evaluating higher education quality. Of these, issues of ensuring and evaluating higher education quality have continually been the mainstream of research on Chinese higher education quality, and there has been an increasing trend of emphasizing ensuring internal quality within schools, emphasizing student participation, and evaluating the effectiveness of student learning. Scholars had a renewed focus on the topics of higher education academic management and student cultivation after 2010, and truly improving the quality of higher education will become a future hot topic of study, however there is an urgent need for further study.

Guiding industries to produce in an effective and environmentally sustainable manner has become a key issue for governments around the world. Over the past 15 years, series of regional and industrial development policies have been introduced by the Chinese government. This has influenced the geographical distribution and energy efficiency performance of China’s industries. This paper quantifies the influence of enterprises geographical distribution on energy efficiency improvement in the paper industry and aims at providing some helpful suggestions on industrial development to policy makers. The main results show that, firstly, the paper industry in eastern China shows obvious characteristic of agglomeration. The average location quotient is 1.2278. However, following the industrial and regional development policies, the characteristic of agglomeration is weakening. Secondly, only when agglomeration reaches a certain level (location quotient is above 0.5447) will industrial agglomeration positively impact on industrial energy efficiency improvement (a 1% increase in agglomeration will increase dynamic energy efficiency by at least 0.23%). Thirdly, the regional development policies carried out by the government slow the pace of energy efficiency improvement in China’s paper industry. The empirical results indicate that the government needs to consider regional characteristics and consciously guide industrial enterprises to concentrate in the dominant area. [ABSTRACT FROM AUTHOR]

- Abstract
β-Agonists are illegal feed additives in the feed industries of many countries, especially China. Here, we report a microfluidic paper-based analytical device (μPAD) coupled with the chemiluminescence (CL) method to provide the sensitive, simple and rapid quantitative detection of β-agonists in swine hair samples. In this study, we found that the β-agonists diminished the CL generated by the reaction of K3[Fe(CN)6] and luminol on μPAD, which was different from that observed in the aqueous solution, and the degree of diminishment was proportional to the concentration of β-agonists. The possible mechanism was discussed as well. Also, this detection method showed a wide linear range (from 4.0 × 10-8 to 1.0 × 10-5 mol L-1) and low limit of detection (2.0 × 10-8 mol L-1) with a low consumption of samples and reagents. Satisfactory recovery values (from 78% to 95%) were achieved. Therefore, our μPAD CL sensor will be favorable to develop a miniaturized instrument for the on-site analysis of β-agonists in swine hair samples.

There are many important cultural relics in China, including many paper relics. Therefore, it is particularly important to find methods of protecting the handwriting in paper relics. This study focuses on the effects acrylic polyurethane materials have on preserving handwriting in paper relics by examining the color change and diffusion of handwriting before and after reinforcement treatments on handwriting materials, including ink, carbon ink, blue-black ink, pure blue ink, red ink, and pencil. The acrylic polyurethane materials have a certain degree of stability and enhance the handwriting of paper relics. We analyzed the acrylic polyurethane reinforcement material in terms of acid resistance, alkali resistance, oxidation resistance, dry heat aging resistance, and durability. The experimental results show that the optimal reinforcement concentration is within 15% for ink, 10% for carbon ink, 20% for blue-black ink, 15% to 20% for pure blue ink, and 3% for red ink and pencil. Finally, the surface of the reinforced paper and handwriting were observed through laser microscopy, SEM, EDS, and infrared spectroscopy and the protective effect of acrylic polyurethane reinforcement material on handwriting was determined.

Carbon emission issues are becoming increasingly severe, and the carbon emissions in shrinking cities, primarily characterized by population loss, are often overlooked and insufficiently studied. This paper focuses on the carbon emissions from county-level administrative units in China's three northeastern provinces from 2001 to 2017. The study scientifically identified shrinking cities and measured the differences in carbon emission characteristics between growing and shrinking cities using the Theil index. Ultimately, the paper constructs a panel spatial econometric model to analyze the factors influencing them and explore their spatial effects. (1) The total carbon emissions in the Three Northeastern Provinces exhibited an inverted U-shaped trend, increasing from 734.21 million tons in 2001 to 1731.73 million tons in 2017, with the Mann–Kendall trend test showing a significant increase; spatially, this manifests as a significant positive spatial autocorrelation. (2) The region has 138 shrinking cities, accounting for over 50%; regarding carbon emission characteristics, the Theil index has consistently remained above 0.18, indicating significant differences between the carbon emissions of growing and shrinking cities. (3) The panel spatial econometric model results show that the influencing factors of carbon emissions in shrinking cities have unique directions, intensities, and spatial effects. In shrinking cities, aside from localized GDP effects and per-capita GDP acting as a suppressant, the population size has a pronounced inhibitory effect on local and surrounding carbon emissions. The analysis reveals significant differences in the carbon emission patterns and mechanisms between growing and shrinking cities; based on these results, the paper proposes differentiated carbon control strategies.

The study shows that, in this duration, the study of Chinese entrepreneurship education experienced a progression through three stages, an "exploratory stage of learning from foreign models," a "developmental stage geared toward employment problems," and a "transformative stage promoting cultivation of student abilities," and featured three primary characteristics, "multidisciplinary fusion," "imbalanced regional distribution," and "policy orientation." In the future, popular fields in the study of entrepreneurship education are to be concentrated in the three areas, namely "entrepreneurship education and talent cultivation," "entrepreneurship education and entrepreneurial environments," and "entrepreneurship education and innovation education."

180. Revisiting Insider-Outsider Research in Comparative and International Education. Bristol Papers in Education: Comparative and International Studies

- Abstract
This volume recognises how many researchers across the social sciences, and in comparative and international education in particular, see themselves as insiders or outsiders or, more pertinently, shifting combinations of both, in the research process. The book revisits and problematises these concepts in an era where the global mobility of researchers and ideas has increased dramatically, and when advances in comparative, qualitative research methodologies seek to be more inclusive, collaborative, participatory, reflexive and nuanced. Collectively, the chapters argue that, in the context of such change, it has become more difficult to categorise and label groups and individuals as being 'inside' or 'outside' systems, professional communities, or research environments. In doing so, it is recognised that individual and group identities can be multiple, flexible and changing such that the boundary between the inside and the outside is permeable, less stable and less easy to draw.The book draws upon an exciting collection of original research carried out in a diversity of educational systems from British, European, Latin American, Indian Ocean, South Asian, African and Chinese contexts and cultures. This develops a deep and innovative reconsideration of key issues that must be faced by all researchers involved in the planning and conduct of in-depth field research. This is a challenging and stimulating methodological contribution, designed to advance critical and reflective thinking while providing practical and accessible guidance, insights and support for new and experienced researchers within and beyond the field of comparative and international education. Following a foreword by Caroline Dyer, the following chapters are presented: (1) Positioning Insider-Outsider Research in the Contemporary Context (Lore Arthur, Elizabeth McNess, Michael Crossley); (2) 'Ethnographic Dazzle' and the Construction of the 'Other': Shifting Boundaries between the Insider and the Outsider (Elizabeth McNess, Lore Arthur, Michael Crossley); (3) Exploring the Concept of Insider' Outsider in Comparative and International Research: Essentialising Culture or Culturally Essential (Anna Robinson-Pant); (4) Constructing the Insider and Outsider in Comparative Research (Peter Kelly) (5) Beyond 'Insiders' and 'Outsiders' in Research for Education Policy-Making? The Discursive Positioning of the Researcher in International and Comparative Education (Nilou M. Hawthorne); (6) Mind the Gap: Reflections on Boundaries and Positioning in Research in International and Comparative Education (Claire Planel); (7) Methodological Challenges: Negotiation, Critical Reflection and the Cultural Other (Nicola Savvides, Joanna Al-Youssef, Mindy Colin, Cecilia Garrido); (8) Insider-Outsider-In Betweener?

In July 2015, China's national legislature brought in prosecutor-led civil environmental public interest litigation ("EPIL") for thirteen selected provincial areas of the country. After a two-year legal experiment, this prosecutor-led civil EPIL system was then established nationwide in July 2017. Yet, can it be said that prosecutorial regulators in China are in fact a paper tiger? Drawing upon content analysis of the 655 prosecutor-led civil EPILs and in-depth interviews with twelve frontline prosecutors and judges, this article examines the dynamics of regulatory practice and the motivation of the Chinese prosecutorial organs to engage in environmental regulation through litigation. Based upon the above two legislative landmarks in the law reform of this area, the regulatory practice of prosecutorial organs can be viewed as having occurred in three stages, with each stage featuring a distinct regulatory model: ad hoc regulation through local innovation before July 2015, forced regulation during the legal experiment from July 2015 to July 2017, and perfunctory regulation after the nationwide establishment of the prosecutor-led civil EPIL system in July 2017. The data shows that the Chinese prosecutorial organs have engaged in a larger number of such lawsuits since the second stage, but they have shown a strong preference for cases with less complicated facts, weak and small defendants, and minor environmental violations. Three factors that influence regulatory motivation are employed to analyse the change in regulatory models: the ambiguity of the law, the top-down political pressure for regulation, and the cost of regulation. This study highlights the very limited effectiveness of vertical political pressure in boosting prosecutorial regulation and the strong impacts of the cost of regulation and the ambiguity of the law. In particular, the high cost of regulation that takes weak regulatory capacity, lack of regulatory autonomy, and the winning rate-oriented performance appraisal system into account have significantly weakened the motivation of prosecutorial organs to pursue civil EPIL. The findings of this study echo the conditions present in the successful prosecutorial regulations in Brazil and contribute to the scholarship about prosecutorial regulations in the field of environmental protection in the Global South.

- Abstract
Objective: To analyze the characteristics of scientific papers in the field of global liver diseases published by Chinese scholars that were retracted for diverse reasons from the Retraction Watch database, so as to provide a reference to publishing-related papers. Methods: The Retraction Watch database was retrieved for retracted papers in the field of global liver disease published by Chinese scholars from March 1, 2008 to January 28, 2021. The regional distribution, source journals, reasons for retraction, publication and retraction times, and others were analyzed. Results: A total of 101 retracted papers that were distributed across 21 provinces/cities were retrieved. Zhejiang area ( n = 17) had the most retracted papers, followed by Shanghai ( n = 14), and Beijing ( n = 11). The vast majority were research papers ( n = 95). The journal PLoS One had the highest number of retracted papers. In terms of time distribution, 2019 ( n = 36) had the most retracted papers. 23 papers, accounting for 8.3% of all retractions, were retracted owing to journal or publisher concerns. Liver cancer (34%), liver transplantation (16%), hepatitis (14%), and others were the main areas of retracted papers. Conclusion: Chinese scholars have a large number of retracted articles in the field of global liver diseases. A journal or publisher chooses to retract a manuscript after investigating and discovering more flawed problems, which, however, require further support, revision, and supervision from the editorial and academic circles.

China is the top emitter of greenhouse gases in the world. Pulp and paper industry is one of eight the strictly regulated industries about carbon emission in China. However, estimates of carbon emissions from China's pulp and paper industry have been suffered from remarkable uncertainty. It is summarized that is aroused by the inaccuracy of factors evaluating energy consumption, and the huge gap between the calculation standards for assessing energy consumption in the production process and the actual level recorded in the factories. This paper re-evaluated the carbon emission of China's pulp and paper industry from the perspective of life cycle assessment, and applied more accurate emission factors, taking account of the actual energy consumption of the production process in factories, to estimate the actual carbon emissions in maximum. It is found that the national standards about the energy consumption quota of China's pulp and paper industry is no longer applicable, and the actual energy consumption regulated in the production process is far better than the advanced level given by the national standards. The greenhouse gas emission have been seriously overestimated approximately 12.00%–56.17% by international organizations. • Life Cycle Analysis of the China's pulp and paper Industry is conducted thoroughly. • The pulp flow of China's pulp and paper Industry is analyzed. • Energy regulated in factory is far better than the national standards' required. • Carbon emissions of China's pulp and paper Industry are overestimated.

188. The Effects of Paper-Based DDL on the Acquisition of Lexico-Grammatical Patterns in L2 Writing

Huang, Zeping
- Abstract
This paper examines whether and to what extent data-driven learning (DDL) activities can improve the lexico-grammatical use of abstract nouns in L2 writing. A topic-based corpus was compiled to develop concordance learning activities, and 40 Chinese students majoring in English were randomly assigned to a control group or an experimental group. At the prewriting stage, both groups were given a list of five abstract nouns: the experimental group was provided with paper-based concordance lines to study the collocations of the words, while the control group was allowed to consult dictionaries for the usage of the words. The written texts of the pre-test, immediate post-test, and delayed post-test were analysed and compared between and within groups. The results showed that the written output by the experimental group, as compared with the control group, contained a higher variety of collocational and colligational patterns and had fewer linguistic errors in using the target abstract nouns. The post-experiment learning journals and questionnaires administered to the experimental group further confirmed that concordance activities encouraged usage-based learning, helped students notice the lexical collocations and prepositional colligations of the target words, and thus improved accuracy and complexity in their productive language. Despite these positive findings, potential problems of using concordance activities for independent learning were also reflected in the students' written output and reported in the learning journals.

- Abstract
Obesity is an important global health problem. Although obesity is not directly related to access to health care or constrained by resource deprivation, overweight status is predominantly found in poor, less-educated populations. This paper seeks to identify the causal role of schooling in affecting obesity among children and adolescents, using new estimation methods that exploit unique panel data on young twins in China. The estimates indicate that higher levels of schooling negatively affect being overweight and positively affect healthy behavior, with a large component of the causal effects due to increased information on the benefits of maintaining a healthy weight. There is also evidence that the higher-income associated with increased schooling increases incentives to invest in health.

- Abstract
This paper estimates the return to an elite university education over a college graduate's career using the CHIP 2013 data. We find a substantial premium for graduating from an elite Chinese university at job entry, but it declines quickly with labor market experience. This pattern is entirely driven by the young cohorts who enter college after the higher education expansion that started in 1999. This pattern is more pronounced in coastal provinces and in economically more developed regions, where individual skills are highly rewarded in the labor market. The initial elite premium and its subsequent decline is found just for males; individual skills are much more consistently rewarded for females than males. The results are consistent with employer learning, where employers pay workers based on more easily observable group characteristics at job entry but rely less on these over time when more accurate information about individual productivity becomes available.

In China, master's students in humanities and social sciences (HSS) are becoming the main target of Chinese-language predatory journals. Existing research has not paid enough attention to why these students publish papers in Chinese-language predatory journals. This research interviewed 30 HSS master's students with different majors using semi-structured interviews and Grounded Theory to analyze the data; it found that research discrimination, research context, self-awareness, and individual demand are the main reasons why students publish papers in Chinese-language predatory journals. This study provides the following suggestions in an effort to solve the problem of Chinese-language predatory journals. First, the Chinese government should draw up a blacklist of Chinese-language predatory journals. Second, the research evaluation departments of Chinese universities and research institutions should evaluate the research results of HSS master's students based on this list. Third, Chinese universities or scientific research institutions should strengthen the training of HSS master tutors and increase their awareness of Chinese-language predatory journals. And finally, Chinese HSS master's students should be taught about the hazards of Chinese-language predatory journals in research integrity and ethics courses, and refuse to publish papers in Chinese-language predatory journals.

- Abstract
Bisphenol A (BPA) is a chemical widely used both in plastics production as a food and beverage container and in thermal papers as a color developer. Dietary consumption is the main route of human exposure to BPA, but dermal absorption through handling different papers might be underestimated or ignored. In this study, BPA in different paper products, including different types of papers, receipts and Chinese currencies, were investigated. BPA was detected in receipts (n = 87) and Chinese currencies (n = 46) with concentrations of 0.17-2.675 × 10(4) μg per g paper and 0.09-288.55 μg per g paper, respectively. Except for parchment papers (n = 3), copy papers (n = 3) and food contact papers (n = 3), BPA was measured in all of the other paper products, with levels of 0.01-6.67 μg per g paper. BPA transferred from thermal papers to common papers increased with the increasing contact pressure. Compared with that in water, the migration speed of BPA was doubled in the synthetic sweat. Washing hands could reduce BPA dermal exposure, and washing hands with lotion was the most efficient way. However, about 19-47% of BPA was still found on hands after different washing methods. Dermal absorption via handling of receipts and papers was estimated to be 36.45 ng per day for the general population and 1.54 × 10(-3) to 248.73 μg per day for a cashier. These values are below the maximum doses recommended by the U.S. Environmental Protection Agency and the European Food Safety Authority. However, due to its uncertain adverse effects on human beings, long-term BPA exposure through dermal absorption should be paid more attention, particularly for some occupational populations.

In order to clarify which types of research is more conducive to improving innovation performance, we use the panel data of key universities in China from 2009 to 2017 for empirical research. The results show that basic research intensity is significantly positive correlated with innovation performance, while paper influence, patent novelty plus the interaction between paper influence and patent novelty are all playing a mediating role between basic research intensity and innovation performance. Furthermore, we use applied research intensity, experimental development intensity and provincial panel data for variables substitution and sample subdivision to carry out robustness test, clarifying the functional mechanism and the heterogeneity of boundary conditions between different types of research intensity and innovation performance. Relevant conclusions are of great theoretical and practical value for optimising the allocation of S&T resources and enriching the theoretical system of innovation research. [ABSTRACT FROM AUTHOR]

Existing studies on environmental policy implementation in China have largely been focused on the inadequacy of environmental policy implementation at local levels and the adversarial campaign‐style enforcement used to remedy it, while overlooked other approaches to addressing environmental issues. We present a case in which a consensual approach was used to control water pollution and identify key factors contributing to the adoption and success of such an approach. The research unit is the process of water pollution control in Shandong Province from 2002 to 2011. During the case period, the pulp and paper industry (the leading polluting source) was regulated with gradually tightened water pollution discharge standards which were made and implemented in a consensual way, surface water quality was greatly improved, and the economic output of the regulated industry grew rapidly. Key factors contributing to the adoption and success of such an approach include the presence of a capable policy entrepreneur who played an important role in policy innovation, forging consensus building in policy making and facilitating consensual policy implementation; the deep and wide involvement of the regulated firms in the policy making process which allowed them to share know‐how and express preferences; and the strong political support from provincial higher‐ups which signaled strong political wills. The findings enrich our understanding of environmental policy enforcement in China by adding a set of internal factors to a literature pool focusing more on the the influence of such external factors as institutional incentiveson policy processes and outcomes.

China's paper industry accounts for a larger proportion of the global paper industry and consumes large amounts of energy. Energy conservation and pollution reduction of the industry have become the focus of China's national development strategy. Energy efficiency is an important index which directly determines the amounts of energy consumption and pollution emissions. To understand the energy efficiency evolution of China's paper industry, this paper establishes an input-output data of the paper industry for 29 provinces in China and applies DEA method and econometric models to estimate and comprehensively discuss the energy efficiency issues based on the framework of total factor efficiency. Our results indicate that China's paper industry has a large energy saving potential even though its energy efficiency has improved during the period 1990–2013. The saving potential is about 65% under the meta-frontier and 44% under the group-frontier. Moreover, there are significant differences between different regions in production technology and energy efficiency. The performance of eastern China is better than other regions. But the technology gaps between the different regions are shrinking and converging over time. Finally, some policy recommendations are proposed to improve the energy efficiency of the industry.
