AbstractSoil is an important part of the ecosystem with significant roles that help human population sustain. Research on prevention and remediation of soil pollution has been carried out when 1985. This study analyzed the 1988–2018 soil remediation dataset in the Web of Science database by bibliometric methods to illustrate the current research trends and hot topics of quantitative analysis and soil remediation in the world. To further identify the major soil contamination topics, we employed social network analysis. The results indicate that the field of soil remediation has entered a stage of rapid progress. The United States has a strong overall strength with the largest number of published articles and larger impact. China ranks second. We identified Journal of hazardous materials as the most influential journal and Chinese academy of sciences as the most influential institution. Academic cooperation showed an increasing trend at the author, institutional, and national levels with an average level of cooperation of 3.57, 1.66, and 1.16, respectively. However, the growth rate of cooperation at the national level is relatively low. In addition, the frequency and co-word analyses of keywords revealed the important research topics. “heavy metals”, “PAH”, “bioremediation”, “Phytoremediation” and “Electrokinetic remediation” were identified as the hot topics. The findings of this study will help researchers understand the status of soil remediation as well as provide guidance for future research.

Abstract In recent years, Chinese scientists have achieved significant progress in paleontological discoveries and scientific studies. Series of studies published in top journals, such as Science, Nature and Proceedings of the National Academy of Sciences of the United States of America (PNAS), have astonished the world by presenting beautiful fossils that furnish robust evidence to enrich the understanding of organismic evolution, major extinctions and stratigraphy. It has been portrayed as the heyday in the paleontology of China. What is the status of the field? What factors have caused the avalanche of fossil discoveries in China? What implications can these new discoveries provide for our understanding of current evolution theories? How, given their significant contribution to the world's paleontology scholarship, can Chinese scientists play a due leadership role in the field? At an online forum organized by the National Science Review (NSR), its associate editor-in-chief, Zhonghe Zhou, asked four scientists in the field as well as NSR executive editor-in-chief Mu-ming Poo to join the discussion.

Music Practice

We employed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) method to systematically review research on music practice from 1928 until June 2020 and identified a total of 3,102 records using our inclusion criteria, of which a total of 296 were eventually selected for the final analysis. We tabulated percentages and frequencies of (a) publications in ten-year periods, (b) type of publications, (c) sampling by geographical location, (d) methodologies used, (e) the top tenth percentile of the most highly cited research, and (f) topics covered. Our analyses reveal that particularly strong growth occurred in the literature between 2000 and 2020. In the literature we retrieved, the most commonly sampled research participants were those in the United States, followed by the United Kingdom and Australia. Quantitative research designs were most prevalent, accounting for two-thirds of all studies reviewed (66.2%), with questionnaires and recordings being the most common methods of data collection. Non-empirical papers (17.5%) as well as studies incorporating qualitative (13.5%) and mixed-methods designs (3.1%) were much less prevalent. Ericsson et al.’s (1993) seminal study of deliberate practice, Driskell et al.’s (1994) review of the research literature on mental practice, and Sloboda et al.’s (1996) study of young musicians were by far the most often cited. Overall, the most common topics addressed were deliberate practice, practice strategies, mental practice, the benefits of practice, metacognition, self-regulation, and self-efficacy, suggesting that music practice is a rich, multifaceted, and complex activity. In light of the findings, recommendations for practice and implications for future research are provided.

The United States is one of the world’s perennial sports powers, yet the pathway to that success is littered with millions of youth athletes who either are not good enough to compete at a higher level or dropout from sport completely due to various personal, social, and organizational factors. These barriers are compounded by a win-at-all-costs mentality that pervades the U.S. sport culture and ultimately disenfranchises many youths from the opportunity to enjoy sport participation throughout their life. The authors argue that principle components in this flawed system are the lack of standardized coach education at the state and national level, weaknesses in the current curricula offered, and difficulties for aspiring coaches accessing existing training programs. In the current paper, the authors (a) briefly review the history of coach education in the United States as well as existing opportunities for coach education at the university, sport-specific, and private sectors; (b) provide a description of the strengths and weaknesses of the current coaching model; and (c) provide recommendations to improve coach education and training in the United States.

Meta Analyses

The adverse health effects of exposure to air pollutants, notably to particulate matter (PM), are well-known, as well as the association with measured or estimated concentration levels. The role of perception can be relevant in exploring effects and pollution control actions. The purpose of this study was to explore studies that analyse people’s perception, together with the measurement of air pollution, in order to elucidate the relationship between them. We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In March 2020, PubMed, EMBASE, and Scopus databases were explored in an attempt to search for studies published from 2000 to 2020. The review included 38 studies, most of which were conducted in China (n = 13) and the United States (n = 11) and published over the last four years (n = 26). Three studies were multicenter investigations, while five articles were based on a national-level survey. The air quality (AQ) was assessed by monitoring stations (n = 24) or dispersion models (n = 7). Many studies were population questionnaire-based, air monitoring and time-series studies, and web-based investigations. A direct association between exposure and perception emerged in 20 studies. This systematic review has shown that most of the studies establish a relationship between risk perception measurement. A broad spectrum of concepts and notions related to perception also emerged, which is undoubtedly an indicator of the wealth of available knowledge and is promising for future research.

The literature on China's social stratification and mobility has discussed the roles of family background and an individual's education attainment. This article aims to extend the existing literature by examining the interplay of these two aspects in fostering a homogeneous group of scientists, the members (yuanshi) of the Chinese Academy of Sciences (CAS, Zhongguo kexueyuan). Since its establishment in 1955, honorific CAS membership has been awarded to outstanding Chinese scientists in their respective fields. As of the end of 1997, a total of 859 Chinese natural scientists, including 40 women, had been elected to the five Academic Divisions of the CAS – Mathematics and Physics, Chemistry, Biological Sciences, Earth Sciences, and Technological Sciences (Table 1) – of whom 610 were alive. They have been renowned, nationally if not internationally, for their academic achievements and contributions, and they have a reputation and prestige similar to those enjoyed by their counterparts in other countries, such as members of the National Academy of Sciences in the United States and fellows of the Royal Society in Britain. Because the occupational prestige of scientists is very high in China, as it is in other countries, and following similar research on the scientific elite, it is reasonable to define CAS members as the Chinese scientific elite.

Research Findings

The nature of the association between language and stuttering in young children has been the focus of debate for many years. One aspect of this ongoing discussion is the status of language abilities in children who stutter (CWS). Available research findings and associated interpretations of these findings are equivocal. This article asserts that an important contributor to the ambiguous nature of this literature may be differences in research traditions and methods that typically have been employed in the study of language development and in the study of stuttering. Cross-disciplinary investigations are inherently complex and, in designing and interpreting research of this nature, a larger set of issues must be considered and more diverse variables must be addressed and/or controlled. This article presents five principles that can be used to guide future research in the area of language and stuttering. These principles also assist in interpreting and applying the current research literature to clinical concerns.

The Status

Online learning is changing the educational landscape despite the limited empirical research and conflicting results about its effectiveness to produce student learning. The purpose of this study was to describe the status of online physical education (OLPE) in the United States. Surveys were sent to forty-five high school online physical education teachers and thirty-two were completed, producing a 71% response rate. Three-fourths of the online physical education teachers focused on a fitness curriculum with emphasis on the cognitive domain. Likewise, it was found that almost three-fourths of the OLPE courses did not meet the national guidelines for secondary schools, of 225 min of PE per week. Most of the courses required physical activity three days per week while six courses required no physical activity. Teachers expressed support, hesitation, and even opposition toward online physical education. This study initiates a descriptive database for future research studies regarding online physical education.

The ArgumentThe Chinese Academy of Sciences, founded in 1949 – the same year as the People's Republic of China – has attempted to use science to speed up technological, economic, and defense-related development, as well as the entire process of modernization. At' the same time, political structures on the development of science have hampered scientific output and kept it to a level that was far below what might have been expected from the creative potential of China's scientists.Early in this century, when modern science was brought to China by foreign missionaries and by scientists and students returning from abroad, only a few people in the country were engaged in scientific research. In 1928 and 1929, two state-run comprehensive research establishments were founded: the Academia Sinica, consisting mainly of scientists who had studied in the United States, and the Peking Academy, consisting mainly of European-trained scientists. Two decades later, a month after the proclamation of the People's Republic of China, a single national scientific research body was founded: the Chinese Academy of Sciences (CAS). This article will review the contribution and status of the CAS, its successes and its failures in the ensuing forty years.
