To extend the application of cost-effective high-yield pulps in packaging, strength and barrier properties are improved by advanced-strength additives or by hot-pressing. The aim of this study is to assess the synergic effects between the two approaches by using nanocellulose as a bulk additive, and by hot-pressing technology. Due to the synergic effect, dry strength increases by 118% while individual improvements are 31% by nanocellulose and 92% by hot-pressing. This effect is higher for mechanical fibrillated cellulose. After hot-pressing, all papers retain more than 22% of their dry strength. Hot-pressing greatly increases the paper’s ability to withstand compressive forces applied in short periods of time by 84%, with a further 30% increase due to the synergic effect of the fibrillated nanocellulose. Hot-pressing and the fibrillated cellulose greatly decrease air permeability (80% and 68%, respectively) for refining pretreated samples, due to the increased fiber flexibility, which increase up to 90% using the combined effect. The tear index increases with the addition of nanocellulose, but this effect is lost after hot-pressing. In general, fibrillation degree has a small effect which means that low- cost nanocellulose could be used in hot-pressed papers, providing products with a good strength and barrier capacity.

The pursuit for sustainability in the papermaking industry calls for the elimination or reduction of synthetic additives and the exploration of renewable and biodegradable alternatives. Cellulose nanofibrils (CNFs), due to their inherent morphological and biochemical properties, are an excellent alternative to synthetic additives. These properties enable CNFs to improve the mechanical, functional, and barrier properties of different types of paper. The nanosize diameter, micrometre length, semicrystalline structure, high strength, and modulus of CNFs have a direct influence on the mechanical properties of paper, such as tensile index, burst index, Scott index, breaking length, tear index, Z-strength, E-modulus, strain at break, and tensile stiffness. This review details the role played by CNFs as an additive to improve strength properties of paper and the factors affecting the improvement in paper quality when CNFs are added as additives. The paper also includes techno-economic aspects of the process and identifies areas that need further research.

The work aims to explore a microscopic observation system of paper surface and achieve high-precision stereoscopic observation with detail characterization of paper surface morphology. Based on the DT-400E precision program-controlled three-dimensional translation stage and KEYENCE LJV-7200 two-dimensional laser scanner, the hardware parts of our own system are developed to scan and transmit point cloud data of paper surface morphology to the computer. The corresponding system software will automatically process the point cloud data acquired from the laser scanner and generate the corresponding vivid 3D model and height histogram. This system scans and characterizes four different types of paper samples, allowing the human eye to visually distinguish the differences in surface morphology as well as automatically calculate the numerical differences in paper surface morphology parameters. The results of the applicability test show that the system is highly efficient in acquiring, observing, and evaluating the topography of the paper surface. The system can not only predict the paper surface quality of printed paper, but can also be extended to the evaluation of 3D printed surfaces.

Papers published in top conferences or journals is an important measure of the innovation ability of institutions, and ranking paper acceptance rate can be helpful for evaluating affiliation potential in academic research. Most studies only focus on the paper quality itself, and apply simple statistical data to estimate the contribution of institutions. In this work, a novel method is proposed by combining different types of features of affiliation and author to predict the paper acceptance at the institutional level. Based on the history of the paper published, this work firstly calculates the affiliation scores, constructs an institutional collaboration network and analyzes the importance of the institutions using network centrality measures. Four measures about the authors’ influence and capability are then extracted to take the contributions of authors into consideration. Finally, a random forest algorithm is adopted to solve the prediction problem of paper acceptance. As a result, this paper improves the ranking of the paper acceptance rate NDCG@20 to 0.865, which is superior to other state-of-the-art approaches. The experimental results show the effectiveness of proposed method, and the information between different types of features can be complementary for predicting paper acceptance rate.

This paper is an attempt to assess if the manufacturing process of paper machine is in statistical control thereby improving the quality of paper being produced in a paper industry at the time of process itself. Quality is the foremost criteria for achieving the business target. Therefore, emphasis was made on controlling the quality of paper at the time of manufacturing process itself, rather than checking the finished lots at a later time. This control on quality will help the industry deduct the small shift in the process parameters and modify the operating characteristics at the time of production itself rather than receiving complaints from customers at a later stage. This paper describes controlling quality at the time of manufacture itself and helps the industry to concentrate on quality at low cost. The researcher has collected primary data at a leading paper industry during October, 2019. Though X-bar and Range charges were primarily used, CUSUM charts were used to sense the minor shifts in manufacturing process, to explore the possibility of adjusting process parameters during manufacture of paper.

Using similarity software to examine the quality of scientific papers is a nuisance. The significance of a scientific paper should be decided by the acknowledged experts. The practice of using the computer program to decide scientific papers must be rescinded or voided.

The authors of this work express their gratitude to Professor V.P. Kucheriavyi for valuable consultations, as well as to two anonymous readers for useful recommendations, which greatly influenced this paper quality.

Papers are the most commonly used substrates. A printable paper must have certain properties. These properties include surface smoothness, air permeability, surface energy, colour of the paper, opacity, whiteness, light fastness, gloss, and coefficient of elongation under force. In addition, a good printable paper should not allow ink to pass between its two surfaces. After the papers are produced, they are subjected to surface treatments in order to improve the above-mentioned properties and to provide extra specification. Surface treatments include calendering, surface sizing and coating processes. While filling the recesses and protrusions on the surface with the coating process, the paper's affinity for the ink is increased, and the penetration of the ink to the other surface of the paper is prevented. In the coating process basically, a filler is dispersed in a binder. In this study, it is aimed to obtain the highest quality and most printable paper by changing the type of binder used in the coating. In this study, equal amount (5% w/w) titanium dioxide filler was used in all coating formulations. In coating formulations; cationic starch, hydroxy ethyl cellulose and polyvinyl alcohol polymers were used as binders. Binder amounts are adjusted according to optimum viscosity. The obtained coating formulations were coated on the paper surface with a laboratory type coating device. Colour, gloss, surface smoothness, air permeability, surface energy and surface morphology of the coated papers were determined. It was printed with magenta offset printing ink on three different types of paper coated with different binders, using the IGT C1 offset printability test device, under 400 N/m2 pressure printing conditions. Colour and gloss measurements of the prints were made. As a result; It was determined that three different binders improved the printability parameters.

This paper examined the coauthorship patterns in Chinese researchers’ cross-border research collaboration in the social sciences based on articles and reviews indexed in the Scopus database (2010–2019). We explored the evolution of coauthorship patterns by year, research field, country/region, and research institution, additionally, the quality of the coauthored publications was examined using four levels of paper quality (Q1–4), citations per paper, and FWCI. We found that collaboration between Chinese and international scholars is very common, and more than 40% of all papers published by Chinese scholars from 2010 to 2019 involved cross-border collaboration. The growth in collaboration was very steady over the past 10 years, increasing by an average of 41% per year. United States scholars are the most common research collaboration partners for Chinese scholars in the social sciences, followed by those in Hong Kong, the United Kingdom, Australia, and Canada. The field of psychology seeks the most collaboration, followed by economics and finance, business and management, and social issues. The percentage of Q1 papers increased from 36% in 2010 to 66% in 2019. Thus, in the past 10 years, Chinese scholars’ cross-border collaboration has grown extensively in terms of both quantity and impact.

The aim of this study was to clarify the anatomical characteristics and predicted paper quality of Eucalyptus urophylla, E. grandis, and E. pellita planted in North Sumatra, Indonesia. In addition, potential hybridization among the three species was explored. The anatomical characteristics of the fiber (length, diameter, and wall thickness), vessels (element length, diameter, and frequency), the proportions of cell types, and the derived wood properties related to pulp and paper quality were examined for these three 9-year-old Eucalyptus species. The obtained results showed that vessel element length as well as fiber and ray parenchyma proportions significantly differed among the three species. Higher fiber and lower ray parenchyma proportions were observed in E. grandis, indicating that this species would be the best mother tree in a hybridization program for pulp and paper utilization, with the other two species complementary for refining the paper quality through this program. In terms of derived wood properties, the three species were considered to be promising raw material for the pulp and paper industry compared to other species that are broadly used as raw material for high-grade pulp and paper-based products.

In most universities, supervisors collaborate with their postgraduate students in writing papers. As a consequence, the relationship between supervisors and postgraduates in the collaborative work becomes the most important one among various relationships between them. In this paper, using a game model, we show that in the current educational system of China, there is a dilemma between supervisors and their postgraduates for their collaborative work – in most cases, either the supervisor or the students will not spend any effort in their joint work. After that, we also investigate whether the two common incentive strategies, i.e., (i) incentives to students, and (ii) incentives to faculties, can solve this dilemma. Our results show that a university can solve the problem by either (i) just using strong incentives to postgraduate students, or (ii) by using a combination of a normal incentive to students and a strong incentive to faculties. Also, we find that when the incentives to the students and to the faculties are below a certain level, all incentives will be just in vain – neither can they improve the serious relationship between supervisors and their postgraduates, nor can they improve the paper quality.

The goal is determining the range of key technological parameters and forecast paper quality parameters of the constrained paper grade based on the development statistical methods of paper production process. At present analysis of the paper quality production is made under laboratory recognitions. It takes a lot of time to determine the paper grade. Besides, some paper can be sent to recycling as defected products. The amount of the defected products of depends on the accuracy of paper grade parameters.

Microfluidics is promising for point-of-care detection in healthcare applications initially involving silicon-based material in microelectromechanical systems (MEMS) technology in combination with materials such as PDMS and glass, resulting in complex fabrication processes. Flexible microfluidic biosensor technology based on paper as a substrate is being pursued to overcome fabrication complexities and making point-of-care detection cost-effective and for one-time usage to avoid disease infection. Paper as a substrate is helpful to mitigate existing rigid wastes and unavoidable pollution. Parameters of paper quality suitable for microfluidic action are different from traditional cellulose paper applications. In microfluidics, realizing microchannels for a controlled flow of liquid in a pre-determined direction is a prime requisite, which is achieved by introducing selective hydrophobicity in the hydrophilic environment employing relevant technology. Microstructures of paper and their role in microfluidic action and related technology of realizing microchannels are presented in this chapter. Traditionally, paper has been used for manual writings using inks initially and later with advanced technology of printing for record-keeping. Print quality paper is composed of cellulose and is hydrophilic in nature, and its fibrous structure offers isotropic microchannels for capillary action making microfluidics possible. Paper-based flexible microfluidic technology provides a versatile and cost-effective technological platform for next-generation smart systems.

The ability of scientific and technological innovation is an important part of a country's comprehensive strength. In recent years, the competition between China and the United States in the field of science and technology has attracted the attention of many scholars. As an important carrier of science and technology, academic data lays a foundation for quantitative analysis of the differences between China and the United States in the field of science and technology. Based on the data of Web of Science, this paper makes a comprehensive comparative analysis of the science and technology level of China and the United States, including the aspects of scientific research input, scientific research output, paper quality and field differences etc. We find that although there are still large gaps between the scientific and technological capabilities of China and the United States, these gaps are gradually narrowing due to the efforts in recent years. The results of this paper can be used for reference to accurately grasp the scientific and technological level of the two countries and formulate relevant policies in the future.

As the use of simulation has become more established in the delivery of healthcare education and training, there has been a corresponding increase in healthcare simulation research. Simulation-based research can be divided into research about simulation (answers research questions in which the focus is on simulation itself) and research through simulation (simulation as a method/tool for research). However, there are barriers, particularly for smaller less well-resourced simulation centres, that may prohibit participation in research. Therefore, it is suggested that quality improvement (QI) through simulation may be a pragmatic way in which simulation centres of all sizes can contribute to improving patient care beyond education and training. QI is defined as systematic, data-guided activities designed to bring about immediate, positive changes in the delivery of healthcare. Although not the case in healthcare, other industries routinely used simulation to support QI. For example, in aviation simulation is used to inform the design of the working environment, the appropriate use of technology, to exercise emergency procedures and to ‘re-fly’ flights following an adverse event as part of the mishap investigation. Integrating simulation within healthcare QI can support the development of novel interventions as well helping to address heretofore intractable issues.

Nanocelluloses (NC) increase mechanical and barrier paper properties allowing the use of paper in applications actually covered by other materials. Despite the exponential increase of information, NC have not been fully implemented in papermaking yet, due to the challenges of using NC. This paper provides a review of the main new findings and emerging possibilities in this field by focusing mainly on: (i) Decoupling the effects of NC on wet-end and paper properties by using synergies with retention aids, chemical modification, or filler preflocculation; (ii) challenges and solutions related to the incorporation of NC in the pulp suspension and its effects on barrier properties; and (iii) characterization needs of NC at an industrial scale. The paper also includes the market perspectives. It is concluded that to solve these challenges specific solutions are required for each paper product and process, being the wet-end optimization the key to decouple NC effects on drainage and paper properties. Furthermore, the effect of NC on recyclability must also be taken into account to reach a compromise solution. This review helps readers find upscale options for using NC in papermaking and identify further research needs within this field.

We study the characteristics of all published papers in the top three finance journals (JF, JFE and RFS), and how these paper characteristics affect the number of citations in Google Scholar and the Web of Science database. First, we find the characteristics in the universalist perspective remain constant while the characteristics in the constructivist and presentation perspectives increase over time. Second, some characteristics are significantly different between the high-impact and the low-impact papers. Third, paper quality, research method, journal placement and paper age are the most important drivers. Last, different drivers play different roles in different journals.

Results of this study demonstrate that enzymatic pretreatment of pulps enables energy savings in the refining process. Pretreatments of NBSK pulp with 3 different commercial xylanases resulted in a faster increase in the pulp freeness that reduced energy input for refining. The partial xylan removal by these enzymes affected the properties of cellulosic pulp and paper. The tensile properties of paper were improved by pretreatment with a pure xylanase while the additional activity of cellulases in the other two tested enzymes negatively influenced the tear resistance. Only the pure xylanase improved the pulp and paper properties. The results of this study provide evidence that the purity of xylanases used in papermaking is of great importance and may decide of paper quality and production costs.

Editors of academic journals make their acceptance or rejection decisions about submitted papers based on their own prior assessment of the intrinsic quality of these papers augmented by the information in reviewer recommendations. In this paper, we theoretically analyze the editorial process of academic journals, and in particular, the editors’ extraction of information about intrinsic paper quality from reviewers. We assume that, if a reviewer’s own research is close to the research area of a paper, he is likely to have greater expertise in evaluating that paper (i.e., be an “expert” reviewer) but is also more likely to be positively or negatively biased with respect to it. On the other hand, “generalist” reviewers, whose own research is further away from the research area of the paper, are likely to be unbiased about it; however, their expertise in evaluating the paper is likely to be lower as well. We further argue that the editorial decisions of journals will deviate considerably from the socially optimal rule of accepting good papers and rejecting bad papers if the above potential reviewer biases are not taken into account by editors when choosing reviewers. We show that editors can make better editorial decisions if they choose the appropriate type of reviewer to evaluate a paper (in the one reviewer case) or the appropriate combination of reviewer types (in the two reviewer case), based on their own prior assessment of submitted papers. We also show that, if the editor can aggregate the information contained in multiple reviews efficiently, two reviewers are better than one as long as the cost of using an additional reviewer is moderate; however, two reviewers may be worse than one if the editor adopts ad hoc decision making rules such as requiring both reviewers to recommend acceptance of a paper before the journal can accept it.

Purpose In a previous paper (McKinnon, 2013), the author questioned the principle and practice of journal ranking and discussed its effects on logistics research. Since then several important developments have occurred prompting a fresh review of the issues. The paper summarises the results of this review with the aim of stimulating further discussion on the subject. Design/methodology/approach New literature on the journal ranking debate has been reviewed. The validity of the journal ranking as a proxy measure of paper quality is explored using data from the UK Research Excellence Framework (REF) assessment. Changes to the ranking of ten logistics/supply chain management (SCM) journals in four listings are analysed, and possible reasons for the relatively low status of the journals are examined. Findings The influence of journal rankings on the academic research process is strengthening while the debate about their legitimacy has intensified. UK REF data cast doubt on the reliability of the journal ranking as an indicator of a paper’s merit. Logistics/SCM journals continue to occupy mid-to-lower tier positions in most listings, though there has been some improvement in their standing. Research limitations/implications The paper aims to alert those managing and undertaking logistics research to the dangers of overreliance on journal rankings in the measurement of research quality and productivity. Practical implications The paper may help logistics/SCM scholars to defend the position of their discipline and resist journal-ranking-induced pressures to marginalise it and devalue its outputs. Social implications In this paper, academic recruitment, promotion and motivation are considered. Originality/value The paper sheds new light on the relationship between journal ranking and individual paper quality, on recent changes in the rating of logistics/SCM journals and on the wider debate about the use of bibliometrics in assessing research quality.

Purpose Innovation plays a pivotal role in a national economy and in the research and development of science and technology. Because the elements, capability and development direction of innovation in various countries are dissimilar, national innovative capacity also varies by country. However, previous studies have predominantly measured national innovative capacity through empirical studies by using a single index of innovation output, ignoring that the forms of innovation are heterogeneous across countries and failing to examine the influence exerted by various innovation models on economic development. Thus, the purpose of this study is to fill this gap by using scientific driving force and technological driving force to present the influence of national innovative capacities on economic development. Design/methodology/approach This study used regression models to test the influence of different national innovative capacities (i.e. scientific and technological driving forces) on economic development and stability. Findings Using the data of 60 countries, this study determined that both scientific and technological driving forces influenced economic development; specifically, scientific driving force affected economic development through technological driving force. Moreover, both research paper quality and patent quality positively influenced economic stability, but patent quality was the mediator. Originality/value This study examined scientific output from both quantitative and qualitative perspectives to determine their influence on economic growth and particularly on economic stability, which lacks dedicated studies. This study strives to bridge this gap in the literature by asserting, from the concept of economic resilience, that high-quality science and technology can strengthen the stability of a country’s economy.

Paper is a material that are produced by pulp that are being compressed, which are one of the leading cause of pollution in an aquatic environment. The aim of the study was to produce a non-chemical treatment natural paper from pomelo albedo waste. The Citrus Maxima (Pomelo) albedo wastes were heated in distilled water and converted into pulp. The pulp was placed in a handmade frame and oven-dried at 60°C for an hour. A paper quality survey was conducted among diploma in pharmacy students (N=36) using a structured interviewing questionnaire. Eighty percent of the respondents agree/strongly agree that different colour of pen, 2B pencil, colour pencil, and crayon can be used as in written or sketch on the albedo pomelo paper. There is no clear tendency to result on the usage of highlighter and correction Tape. Most of the respondents disagree with smoothness, elasticity, and waterproof of the paper. The Pomelo paper is potential as an alternative eco-friendly natural paper for writing and colouring with different materials. The pomelo paper making process can be shared as an educational kit, especially to children, to expose them on the papermaking process.

Background: The number of papers published by an institution is acknowledged as an easy-to-understand research outcome. However, the quantity as well as the quality of research papers needs to be assessed. Methods: To determine the relation between the number of published papers and paper quality, a survey was conducted to assess publications focusing on interventional clinical trials reported by 11 core clinical research hospitals. A score was calculated for each paper using Système d’interrogation, de gestionet d’analyse des publications scientifiques scoring system, allowing for a clinical paper quality assessment independent of the field. Paper quality was defined as the relative Journal impact factor (IF) total score/number of papers. Results: We surveyed 580 clinical trial papers. For each of the 11 medical institutions (a–k), respectively, the following was found: number of published papers: a:66, b:64, c:61, d:56, e:54, f:51, g:46, h:46, i:46, j:45, k:45 (median: 51, maximum: 66, minimum: 45); total Journal IF: a:204, b:252, c:207, d:225, e:257, f:164, g:216, h:190, i:156, j:179, k:219 (median: 207, maximum: 257, minimum: 156); relative Journal IF total score: a:244, b:272, c:260, d:299, e:268, f:215, g:225, h:208, i:189, j:223, k:218 (median: 225, maximum: 299, minimum: 189); and paper quality (relative Journal IF total score/number of papers): a:3.70, b:4.25, c:4.26, d:5.34, e:4.96, f:4.22, g:4.89, h:4.52, i:4.11, j:4.96, k:4.84 (median: 4.52, maximum: 5.34, minimum: 3.70). Additionally, no significant relation was found between the number of published papers and paper quality (correlation coefficient, −0.33, P = 0.32). Conclusions: The number of published papers does not correspond to paper quality. When assessing an institution’s ability to perform clinical research, an assessment of paper quality should be included along with the number of published papers.
