A scientific paper's citation represents its influence, which is the most intuitive indicator to access the quality of papers. This paper mainly adopts the social network analysis method, using the authors and the keywords of sports industry papers in China to constitute the networks of collaboration and knowledge, to explore effects of the degree centrality of authors and keywords and the structural hole of authors and keywords on the citation of papers in the collaboration and knowledge networks and draw the following conclusions: (1) as for collaboration networks, the degree centrality at the paper level is positively correlated with citations; (2) in the collaboration network, the positive correlation between the structural hole at the paper level and citations does not exist; (3) within knowledge networks, an inverted- U shape was found between degree centrality and paper's citation; and (4) within knowledge networks, a positive correlation is in existence between the structural hole of papers and their citation. This study synthesizes the already widely used collaboration network with the knowledge network constructed through keywords, distinguishes from the previous network features focusing at the author level, and explores research projects of Chinese Sports Industry from the paper level, providing a new perspective for the research of sports industry in China, complementing the methods and ideas of sports industry research, as well as providing a reference for the research in other disciplinary fields.

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.

This article explores the digitalization of traditional funeral joss paper into digital commodities through the case study of the Chinese online cemetery 00tang.com. Joss paper are paper replicas of everyday items such as money and objects that are ritually burned as a form of symbolic offering to the deceased in accordance with traditional Chinese practices of ancestor worship. Using both ethnographic interviews and discursive interface analysis, I look at how the remediation of spiritual joss paper into digital objects complicates perceived dichotomy between the gift and commodity that requires new ways of thinking about the acts of social reciprocity, indebtedness, and obligation. Drawing on established literature relating to gift and digital economies, I argue 00tang's digitization of joss paper on internet cemeteries is reflexive of the biopolitical means by which the state and market forces work to subsume traditional ancestor worship into controllable and commodifiable labor of mourning. Here, the subversive wastefulness of the gift is replaced by its accumulation and preservation online. Digitization in this regard highlights the process by which objects take on different materiality, values, aesthetics, and productive labor practices, all of which fundamentally alters the symbolic regimes of death and the ritual gift economy in China.

The coating technique, supposedly invented by Chinese papermakers no later than the 3rd century AD, greatly improved paper sheets' qualities of color, texture, writability, and printability. Alongside the dispersal of papermaking and surface-treatment techniques beyond China, coated papers were manufactured and used in many other regions of the world. Understanding the manufacture of coated papers, therefore, is crucial for perceiving how surface treatments were developed to meet the need for paper with enhanced properties. However, the characterization of coating and coating pigments on ancient Chinese papers has long remained an unsolved issue, and previous studies on this topic have often produced inconclusive results. To explore a non-invasive methodology that can more reliably characterize coated papers and the coating pigment on them, this article presents the results of a pilot study that applied micro-computed tomography (micro-CT) and Raman spectroscopy to samples of three Qing Dynasty (1644–1911 AD) papers and two handmade papers manufactured in China in the 1990s. Micro-CT revealed the coating layer(s) on Lajian (waxed coated paper) and Lengjinjian (gold-dusted paper) of the Qing Dynasty and characterized the modern raw xuan and bamboo papers as uncoated. Raman spectroscopy, together with handheld X-ray fluorescence analysis, identified the mineral-based pigment in the coating layer, suggesting the use of lead white or kaolin as the coating pigment. Additionally, Raman analysis confirmed the use of other mineral pigments (red lead and cinnabar), beeswax, and organic dyes (gamboge, kermesic acid, and possibly purpurin) in the manufacture of Lajian and Lengjinjian papers. The combination of micro-CT and Raman spectroscopy, it is therefore suggested, is a practical, more reliable approach for non-invasive investigation of coating and coating pigments on ancient Chinese paper specimens.

Subject to various restrictive requirements on project application and completion, funded projects are often affected by funding policies for the selection of research objects. This study explored the impact of scientific research funding policies on the funding and research by comparing the topic distribution of awards and papers. A total of 1,870 awards and 16,491 papers of the National Social Science Foundation of China (NSSFC) in library and information science (LIS) were collected from a Chinese research project database. According to the results, the growth rate of awards on most topics is higher than that of papers, while the growth rate of papers on the relevant topics to users, technology, and metrology is higher than that of awards. It was found out in the study that the topics funded by NSSFC were imbalanced. NSSFC provides much more funding to traditional topics rather than emerging topics. As indicated by the funding provided to the projects on traditional topics for research on a large number of papers on emerging topics, however, the innovation and diversity of academic research have yet to be restricted. This study demonstrated that the effect of funding policies on the research topics in LIS is significant. Topic suggestions and funding structure of NSSFC have more impacts on award topics than on paper topics. The influence of NSSFC-recommended topics on paper topics is declining year by year. Additionally, awards with high funding intensity are more susceptible to topic suggestions. [ABSTRACT FROM AUTHOR]

A PVA matrix was used to suppress infiltration and coffee-ring effects during colorimetric analysis on a paper substrate and improve the trace-level detection of nickel ions (Ni2+) in environmental samples. To improve the color response, a cross-linked PVA matrix was used to anchor the indicator reagent of Ni2+ on the surface of the porous paper substrate as well as reduce evaporation flow by increasing hydrogen bonding in the sample droplet. These phenomena mitigated the loss of color signal by suppressing infiltration and coffee-ring effects. Under optimized conditions, including crosslinker concentration and addition order, type of commercial filter paper, and loading volume of the PVA/indicator mixture, the sensor obtained a limit of detection (LOD) as low as 0.92 ppm and a notable linear behavior of R2 > 0.97 at a linear range of 0.5–50 ppm, which is sufficient for the detection of legal maximum residue limit (MRL) of Ni2+ in wastewaters in China. The PVA-assisted sensor showed good selectivity to most metal ions and could work at different pH levels ranging from 3 to 9. The sensor also exhibited highly sensitive and stable performance in repetitive measurements and had a shelf-life of more than 3 months. These results suggest that our work provides a facile approach to improving the sensitivity and reliability of paper-based sensors for monitoring trace-level Ni2+ concentration in aqueous samples with good selectivity and prolonged shelf-life.

Melamine-impregnated paper decorated medium-density fiberboard (MIPMDF) is the main board used for wooden furniture materials in China, and the formaldehyde released from the board and furniture products is harmful to human beings and is a wide concern. This paper aimed to pay attention to the formaldehyde emission of MIP-MDF and its furniture products. This study utilized a 1 m³climatic chamber to measure the formaldehyde emission of MIP-MDF and nightstand made of MIP-MDF in relation to the time and load factors. According to the results, in the 2 to 24 h stage, the emission of formaldehyde in the nightstand made of MIPMDF materials changed significantly, and the overall trend showed a changing trend of first increasing and then declining. The formaldehyde emission of MIP-MDF stabilized after 40 h, while the formaldehyde emission of the nightstand stabilized after 60 h. As time passed, the formaldehyde emission changes of MIP-MDF and nightstand were almost the same. The formaldehyde emission of MIP-MDF and nightstand has a specific positive correlation with the carrying load. With increased carrying loads, the formaldehyde emission tends to increase, but the degree of influence gradually decreases with the addition of the carrying loads. [ABSTRACT FROM AUTHOR]

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.
