Background A central construct in Schema Therapy (ST) is that of a schema mode, describing the current emotional-cognitive-behavioral state. Initially, 10 modes were described. Over time, with the world-wide increasing and broader application of ST to various disorders, additional schema modes were identified, mainly based on clinical impressions. Thus, the need for a new, theoretically based, cross-cultural taxonomy of modes emerged. Methods An international workgroup started from scratch to identify an extensive taxonomy of modes, based on (a) extending the theory underlying ST with new insights on needs, and (b) recent research on ST theory supporting that modes represent combinations of activated schemas and coping. Results We propose to add two emotional needs to the original five core needs that theoretically underpin the development of early maladaptive schemas (EMSs), i.e., the need for Self-Coherence, and the need for Fairness, leading to three new EMSs, i.e. Lack of a Coherent Identity, Lack of a Meaningful World, and Unfairness. When rethinking the purpose behind the different ways of coping with EMS-activation, we came up with new labels for two of those: Resignation instead of Surrender, and Inversion instead of Overcompensation. By systematically combining EMSs and ways of coping we derived a set of schema modes that can be empirically tested. Conclusions With this project, we hope to contribute to the further development of ST and its application across the world.

The purpose of this study was to investigate the impact of mLearning or mobile device practice on the attention and accuracy of student's use of math concepts, specifically, telling time. A single subject, alternating treatment design was used to compare mLearning to paper and pencil practice in four 3rd grade male students. Results were mixed; two children were observed to be more on-task during the mLearning practice, and two children were observed to perform similarly across both conditions. Additionally, two children performed similarly on correctly completed problems across both conditions, and two children performed better using paper and pencil practice. All students completed more math problems during the paper and pencil practice.

International audience; In 2014 leading publishers withdrew more than 120 nonsensical publications automatically generated with the SCIgen program. Casual observations suggested that similar problematic papers are still published and sold, without follow-up retractions. No systematic screening has been performed and the prevalence of such nonsensical publications in the scientific literature is unknown. Our contribution is 2-fold. First, we designed a detector that combs the scientific literature for grammar-based computer-generated papers. Applied to SCIgen, it has a 83.6% precision. Second, we performed a scientometric study of the 243 detected SCIgen-papers from 19 publishers. We estimate the prevalence of SCIgen-papers to be 75 per million papers in Information and Computing Sciences. Only 19% of the 243 problematic papers were dealt with: formal retraction (12) or silent removal (34). Publishers still serve and sometimes sell the remaining 197 papers without any caveat. We found evidence of citation manipulation via edited SCIgen bibliographies. This work reveals metric gaming up to the point of absurdity: fraudsters publish nonsensical algorithmically generated papers featuring genuine references. It stresses the need to screen papers for nonsense before peer-review and chase citation manipulation in published papers. Overall, this is yet another illustration of the harmful effects of the pressure to publish or perish.

Methodological mistakes, data errors, and scientific misconduct are considered prevalent problems in science that are often difficult to detect. In this study, we explore the potential of using data from Twitter for discovering problems with publications. In this case study, we analyzed tweet texts of three retracted publications about COVID-19 (Coronavirus disease 2019)/SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) and their retraction notices. We did not find early warning signs in tweet texts regarding one publication, but we did find tweets that casted doubt on the validity of the two other publications shortly after their publication date. An extension of our current work might lead to an early warning system that makes the scientific community aware of problems with certain publications. Other sources, such as blogs or post-publication peer-review sites, could be included in such an early warning system. The methodology proposed in this case study should be validated using larger publication sets that also include a control group, i.e., publications that were not retracted.

This study aims at understanding the role of the tools chosen throughout the processes of solving a non-routine mathematical problem and communicating its solution. In assuming that problem-solving is a synchronous activity of mathematization and expression of mathematical thinking we take our proposed Mathematical Problem Solving with Technology (MPST) model to analyze the processes of solving-and-expressing-problems. Resorting to qualitative methods for data collection and analysis, we report on the case of an 8th grader working on a covariation problem to examine the role that paper-and-pencil and digital tools play in the development of a conceptual model of the situation. We found that the resources used throughout the solving-and-expressing activity influenced the depth of the conceptual model developed, within a process of progressive mathematization. Whereas paper-and-pencil led to the emergence of a conceptual model based on exploring particular cases, the digital transformation of the solution was triggered by the process of communicating its mathematical justification and expanded the previous model. Moreover, the complexity of this activity is evidenced by its multiple sequences of processes. Finally, the integration process seems crucial as the concomitant use of technological and mathematical resources precedes major advancements in the expansion of the conceptual model.

Feedback is beneficial to students’ learning process and overall achievement, but one of the common complaints from students about college education is regarding feedback. So, this study aimed to examine whether digital written feedback positively influences students’ learning experience and attitude toward learning. Digital written feedback refers to feedback provided through a learning management system as handwritten feedback added to a scanned copy of the student’s paper-based assessment using a smart pad and smart pencil. The study surveyed a diverse set of college students’ (n = 175) perceptions regarding feedback satisfaction, learning satisfaction, the usefulness of digital written feedback, and perceived achievement via an online survey. A one-way analysis of variance found a significant difference between feedback satisfaction and learning satisfaction according to the feedback method. A multiple regression analysis indicated the satisfaction and perceived usefulness of digital written feedback predicted perceived achievement. From the students’ open responses regarding the benefits of digital written feedback, five themes emerged, namely usability, psychological relief, accessibility, self-regulation, and acceptance. The implications for digital written feedback are discussed.

In this paper, we present a system for automatic evaluation of the quality of a question paper. Question paper plays a major role in educational assessment. The quality of a question paper is crucial to fulfilling the purpose of the assessment. In many education sectors, question papers are prepared manually. A prior analysis of a question paper might help in finding the errors in the question paper, and better achieving the goals of the assessment. In this experiment, we focus on higher education in the technical domain. First, we conducted a student survey to identify the key factors that affect the quality of a question paper. The top factors we identified are question relevance, question difficulty, and time requirement. We explored the strategies to handle these factors and implemented them. We employ various concepts and techniques for the implementation. The system finally assigns a numerical quality score against these factors. The system is evaluated using a set of question papers collected from various sources. The experimental results show that the proposed system is quite promising.

The paper industry is an essential but energy-intensive economic sector. This study aims to propose an appropriate inventory method to first determine the GHG emission factor in the life cycle of paper products of Vietnam. The approach overcomes the limitations of the ISO 14067 method by including the environmental burdens from the paper mill’s processes. In 2018, the amount of GHG emitted from cradle to gate when producing a ton of carton box, writing paper, and tissue products ({\text{EF}}_{{\text{CO}}_{\text{2eq}}}) was 1,366 kg CO2eq, 1,224 kg CO2eq, and 751 kg CO2eq, respectively. High energy intensity is identified as the main reason that causes high life cycle analysis (LCA) GHG emission factors and virgin paper-based products often emit higher LCA GHG amounts than recycled paper-based products. To reduce the emission, the Vietnamese paper mills should increase the use of recycled paper and replace fossil fuels with environmentally friendly energy resources.

A series of industrial experimental tests on the freeze treatment of colloidal sludge lignin precipitates was carried out under natural conditions. Changes in the physical and chemical properties of the precipitates were studied. It is established that three fractions are formed following the freeze treatment of colloidal sludge lignin precipitates, including demineralized water (up to 25 %), mineralized water (up to 15 %) and a restructured colloidal precipitate (up to 60 %). The total volume of the precipitate is shown to decrease to 40 %. Freezing precipitation of colloidal lignin slurry of "the Baikal Pulp and Paper Mill" leads to a decrease in toxicity from the third to the fifth class of danger. On the basis of frozen sediments, the lignin sludge of OJSC Baikal Pulp and Paper Mill with the addition of other waste from the Baikal region, a fertile soil was obtained that corresponds to GOST R 54651-2011 "Organic fertilizers on the basis of sewage sludge. Specifications".

Throughout this study technology and especially mobile phones was utilized in EFL classrooms in order to see whether it can influence the process of vocabulary formative assessment and consequently improve vocabulary learning of Iranian pre-intermediate EFL learners or not. Two groups of pre-intermediate EFL learners participated in this study. Regarding the first group (FMA) the vocabulary learning of learners was assessed formatively during ten sessions using Socrative mobile application. The vocabulary learning of the second group (FPA) was also assessed formatively but paper and pen were the instruments used by instructor and students to take the tests. After applying quasi-experimental research design including pretest, treatment and posttest and after running independent sample t tests to posttest scores, the results showed that those pre-intermediate EFL learners attending in the group where vocabulary gain was assessed formatively using mobile application named Socrative performed significantly better in posttest than group assessed formatively based on paper and pen (Sig=0.03

This study introduces a novel geotechnical composite material comprising two types of fill material sourced from the paper industry-deinking paper sludge ash (DPSA) and deinking paper sludge (DPS). Five composites with different DPSA and DPS contents were investigated. Two composites were selected for further analyses. The technology and procedure for composite installation were implemented in field tests. The composites with 80% and 70% DPSA exhibited the elasticity required to withstand minor landslide slip deformations, in addition to achieving sufficiently high values of uniaxial compressive strength. The composites had a low maximum dry density value, which led to fewer settlements in the entire support structure. The enhanced shear characteristics can enable the construction of a thinner retaining wall. The delay between preparation and installation of the composites was further investigated. The field tests confirmed that the composites with 80% and 70% DPSA can be installed on the construction site 4 h and even 24 h after mixing. In 2018, a retaining wall structure with 70% DPSA and 30% DPS was successfully implemented near a railway line using conventional technology as followed-up research to the herein presented study. Results have been derived from work performed in the scope of the H2020 Paperchain project in which novel circular economy models centered on the valorization of the waste streams generated by the pulp and paper industry as secondary raw material for several resource-intensive sectors, including the construction sector, have been developed. Environmental benefits are savings in natural raw materials, reduction of landfill disposal as well as CO2 emission reduction. Nasl. z nasl. zaslona. Opis vira z dne 16. 11. 2021. Št. članka 22363.

Following Swales’ (1990) influential study on research article (RA) introductions, some attention has increasingly been paid to other rhetorical units of both expert and learners’ writing, including titles. A key and effective discursive means through which titles are constructed and presented is the syntactic configuration. The present study, thus, investigates the syntactic structures employed by authors of conference paper titles (CPTs) in Applied Linguistics. A qualitative content analysis was employed to study a corpus of 592 CPTs from a popular conference for researchers, scholars, and practitioners of Applied Linguistics worldwide, supported by some descriptive statistics. The analysis of data study identified three main title styles: Single Unit Title, Compound Unit Title, and Complex Unit Title. The analysis showed that, out of these three title styles, Compound Unit Titles were preferred by researchers. Further, the colon was the dominantly used punctuation mark in separating the components of Compound Unit titles. The final point was that authors preferred prepositional phrases in the post modification of the noun phrase structure of CPTs. The findings of this study have implications for the scholarship on titlelogy, academic writing pedagogy as well as further research.

In recent history, the Panama Papers have comprised one of the largest and most influential leaks detailing information on offshore entities, company officers and financial (and legal) intermediaries, and has led to a global exposé of corruption and tax evasion. A systematic analysis of this information can provide valuable insights into the structure and properties of these entities and the relations between them. Network science can be applied as a scientific framework for understanding the structure of such relational, heterogeneous datasets at scale. In this article, we use an existing, relational version of the Panama Papers to selectively construct various networks, and then study the properties of the underlying system using well-defined analytical methods from network science, including degree properties, country assortativity analyses, connectivity and single-point network metrics like transitivity and density. We also illustrate significant structural features in these networks by conducting a triad census and exploring the networks’ core-periphery structure. Together, these results are used to show that the Panama Papers constitute a distinct class of networks that differ significantly from ordinary social and information networks. We also propose, construct and analyze ‘higher-order’ networks from the raw data, such as a ‘social’ network of officers. We confirm that some of these higher-order networks also show significant non-random deviations from expected or typical behavior, including in their degree distributions.

We report the findings of a diachronic study of 100 research paper abstracts published in four different periods (from 1943 to 2018) in Monthly Notices of the Royal Astronomical Society, one of the most prestigious astrophysics journals written in English. Our main results show that research paper abstracts have evolved over time in the sense that they have become longer, more informative and more precise. They also reveal an overall increase in the number of authors, active and modal verbs, self-mentions and compound groups per total number of words. Likewise, compound structures are becoming more and more complex. These outcomes may be explained in terms of a rising collaboration scenario and an attempt to increase authors’ visibility.

This paper compares Léon Walras’ and Augustin Cournot’s views on monetary regulation. It shows that whereas Cournot believed discretionary monetary regulation to be convenient and acceptable, Walras held that the only acceptable monetary system is based exclusively on the stability of the value of money under a monetary rule following a strict equivalence between metallic reserves and a pure medium of exchange form of money. The paper also advances Cournot understood more clearly than Walras the evolution of the monetary system of their days because Walras was trying to guarantee the coherence of his pure theory with his applied theory, which made him unable to accept the evolution toward a monetary system based on fiat money. Este artículo compara las teorías de Léon Walras y Augustin Cournot sobre regulación monetaria. Demuestra que, si bien Cournot creía que era conveniente y aceptable la regulación monetaria discrecional, Walras sostuvo que el único sistema monetario aceptable es el basado en la estabilidad del valor del dinero bajo una regla monetaria que siga una estricta equivalencia entre las reservas metálicas y el dinero, considerado como puro medio de cambio. El artículo también apunta a que Cournot entendió mejor que Walras la evolución del sistema monetario de su época dado que Walras trataba de mantener la coherencia de su teoría pura con su teoría aplicada, lo que hizo que fuera incapaz de aceptar la evolución hacia un sistema monetario basado en dinero fiduciario.

The purpose of this paper is to present evidence that supports the notion that the primary reason behind marginal bone loss and implant failure is immune-based and that bacterial actions in the great majority of problematic cases are of a secondary nature.The paper is written as a narrative review.Evidence is presented that commercially pure titanium is not biologically inert, but instead activates the innate immune system of the body. For its function, the clinical implant is dependent on an immune/inflammatory defense against bacteria. Biologic models such as ligature studies have incorrectly assumed that the primary response causing marginal bone loss is due to bacterial action. In reality, bacterial actions are secondary to an imbalance of the innate immune system caused by the combination of titanium implants and ligatures, ie, nonself. This immunologic imbalance may lead to marginal bone resorption even in the absence of bacteria.Marginal bone loss and imminent oral implant failure cannot be properly analyzed without a clear understanding of immunologically caused tissue responses.

This study was conducted to examine students’ performance in paper-based and online-based tests. In the context of the study, students’ performances were considered in the General Physics course between 2014 and 2015 and 2018–2019 academic years. The participants of this study are 417 students of Engineering and Science faculties at a public university of Kyrgyz Republic. Students’ achievement scores in paper-based and online-based tests were obtained and appropriate statistical analysis methods were employed. According to the results, students’ demographic data (i.e. gender, faculty and major) have different effects on their performance, and students performed better in online-based tests compared to paper-based tests. Additionally, the study aimed to analyze instructor perceptions related to testing types that interviews were conducted with 26 instructors of the General Physics course. The majority of the instructors indicated that they experienced difficulties related to the traditional form of evaluation due to the following reasons: lack of time to give personal feedback to each student, lack of time for objective evaluation, and difficulty of evaluation of crowded student groups. Therefore, they indicated the necessity of online test implementation in the context of the General Physics course.

This article aims to outline main directions of the security strategy of the People’s Republic of China basing on the analysis of the Defence White Paper of July 2019, the political practice of the Beijing authorities as well as internal and international situation. Having analysed the above mentioned areas, the author concludes that the contemporary strategy of the PRC is internally subordinated to maintaining territorial, political and social integrity, including primarily legitimization of the power of the Communist Party of China. Externally, the strategy is oriented at reversing the unfavourable balance of forces in the Asia-Pacific region and weakening of the US military advantage. Those two directions determine the activities of the Chinese state in such specific areas as: modernization of the People’s Liberation Army (PLA), the relations with Taiwan and claims concerning South China Sea. The Defence White Paper is aimed at contrasting the unilateral and hegemonic policy of the United States (as the authors of the document see it) with the defensive and moderate activities of China. The narration serves to convince international players to remain neutral or engage in collaboration with China in the face of intensifying military, economic and political pressure on the part of the USA. China has entered a “critical moment” of its development and the response of the Beijing authorities to the challenges of internal development and external pressures will determine whether in the 21st century it will become a superpower.

Purpose: Data papers are a promising genre of scholarly communication, in which research data are described, shared, and published. Rich documentation of data, including adequate contextual information, enhances the potential of data reuse. This study investigated the extent to which the components of data papers specified by journals represented the types of contextual information necessary for data reuse.Methods: A content analysis of 15 data paper templates/guidelines from 24 data journals indexed by the Web of Science was performed. A coding scheme was developed based on previous studies, consisting of four categories: general data set properties, data production information, repository information, and reuse information.Results: Only a few types of contextual information were commonly requested by the journals. Except data format information and file names, general data set properties were specified less often than other categories of contextual information. Researchers were frequently asked to provide data production information, such as information on the data collection, data producer, and related project. Repository information focused on data identifiers, while information about repository reputation and curation practices was rarely requested. Reuse information mostly involved advice on the reuse of data and terms of use.Conclusion: These findings imply that data journals should provide a more standardized set of data paper components to inform reusers of relevant contextual information in a consistent manner. Information about repository reputation and curation could also be provided by data journals to complement the repository information provided by the authors of data papers and to help researchers evaluate the reusability of data.

This paper investigates the impact of institutes and papers over time based on the heterogeneous institution-citation network. A new model, IPRank, is introduced to measure the impact of institution and paper simultaneously. This model utilises the heterogeneous structural measure method to unveil the impact of institution and paper, reflecting the effects of citation, institution, and structural measure. To evaluate the performance, the model first constructs a heterogeneous institution-citation network based on the American Physical Society (APS) dataset. Subsequently, PageRank is used to quantify the impact of institution and paper. Finally, impacts of same institution are merged, and the ranking of institutions and papers is calculated. Experimental results show that the IPRank model better identifies universities that host Nobel Prize laureates, demonstrating that the proposed technique well reflects impactful research.

Green Public Procurement is currently a voluntary instrument to promote Sustainable Consumption and Production and Sustainable Industrial Policy. Surveys in this field help to understand how individual States, Public Authorities and Organizations, are approaching this voluntary instrument and thus how far they support Eco-Innovations and Sustainable Economy. Our survey focuses on mapping of units of local self-governments in the Slovak Republic that carried out Green Public Procurement in the category of paper products through the Electronic Contracting System (ECS) in 2017. We consider local self-government units to be major consumers of paper products, especially because of their extensive administration, what makes them a target group to promote the use of Green Public Procurement in a given category in practice. The total number of contracts awarded through the ECS in 2017 was 471. As the results show, the share of Green Public Procurements in the total number of Public Procurements in the Slovak Republic in 2017 was not satisfactory. In order to improve the situation, it is necessary to further deepen the targeted dissemination of examples of good practice in Green Public Procurement.

Background Adequately measuring resilience is important to support young people and children who may need to access resources through social work or educational settings. A widely accepted measure of youth resilience has been developed previously and has been shown to be suitable for vulnerable youth. While the measure is completed by the young person on paper, it has been designed to be worked through with a teacher or social worker in case further clarification is required. However, this method is time consuming and, when faced with large groups of pupils who need assessment, can be overwhelming for schools and practitioners. This study assesses app software with a built-in avatar that can guide young persons through the assessment and its interpretation. Objective Our primary objective is to compare the reliability and psychometric properties of a mobile software app to a paper version of the Child and Youth Resilience measure (CYRM-28). Second, this study assesses the use of the CYRM-28 in a Scottish youth population (aged 11-18 years). Methods Following focus groups and discussion with teachers, social workers, and young people, an avatar was developed by a software company and integrated into an android smartphone app designed to ask questions via the device’s inbuilt text-to-voice engine. In total, 714 students from 2 schools in North East Scotland completed either a paper version or app version of the CYRM-28. A cross-sectional design was used, and students completed their allocated version twice, with a 2-week period in between each testing. All participants could request clarification either from a guidance teacher (paper version) or from the in-built software glossary (app version). Results Test and retest correlations showed that the app version performed better than the paper version of the questionnaire (paper version: r303=0.81; P Conclusions ALEX, an avatar with an integrated voice guide, had higher reliability when measuring resilience than a paper version with teacher assistance. The CFA reports similar structure using the avatar when compared against the original validation.

This research investigates the use of Data-driven learning (DDL) tasks in the teaching and learning of acronyms in a specialised corpus. Our target population is professional military staff (n=16). The researchers collected and analysed the Salvage and Rescue of Submarines Corpus (SAR) where the patterning of acronyms, neglected in English for Specific Purposes (ESP), plays a substantial role. Using a mixed-methods methodology, this research looked at the students’ interaction with DDL, as well as at the subsequent interviews with the students. Deductive and inductive paper-based DDL tasks with concordance lines of acronyms were used with two groups of students of different rank. Both groups found the tasks challenging and showed mixed reactions towards concordance lines. While there has been a much-needed emphasis on tools and corpus methods training in DDL, we suggest that conversations with adult, professional students about the nature of instructed language learning and language patterning are absolutely essential to promote a more active learner role in DDL approaches.

This article is an ethnographic exploration of a promiscuously present and instantly recognisable legal and cultural artefact in India, the stamp paper document under the Indian Stamp Act, 1899. The ‘stamp paper’ is a documentary form that is constantly escaping from its legal moorings in revenue and evidentiary law, and is being replicated, mimed and recommissioned, both in form and in substance, and in ways which blur the domains of the legal, the quasi-legal and the non-legal. Its bureaucratic authority is produced through protocols and rituals of writing, verification, identification, attestation and authorisation performed by paper workers such as court typists, stamp vendors, notaries and oath commissioners. Yet the stamp paper is simultaneously viewed as notoriously fraudulent and legally invalid—its use redundant and truth functionaries infamously corruptible. Focusing on the materiality of the stamp paper, as it circulates through the interstitial spaces of Patiala House Court Complex in New Delhi, this article seeks to address this curious paradox and provides an account of the social life of law through the travels of an emblematic yet dubious legal form.

Paper aims This study identifies fundamental characteristics for developing a paper-based thesis (PBT), providing some recommendations to researchers who decide for this academic research report. Originality This paper contributes to the literature by providing guidance to develop PBTs, which has been attracting researchers' interest because it demonstrates publication capacity and potential as a researcher. Additionally, it is still not entirely clear which issues and countermeasures researchers should address when choosing the paper-based structure. Research method The authors searched for articles of PBTs already published, institutional documents (e.g., regulations for conducting PBTs in Brazil and abroad) and journal papers concerning this subject. A content and document analysis were conducted in the papers and PBT internal regulations, respectively. Main findings Results indicate five main factors that impact the success of a PBT approach: (i) the initial planning for this academic model; (ii) alignment between the articles and the thesis/dissertation; (iii) research design construction; (iv) copyrights requirements; and (v) issues regarding co-authorship. Based on that, the study also builds some guidelines to structure a robust PBT. Implications for theory and practice Our recommendations might be meaningful to scholars and researchers bring more theoretical, empirical, and structural robustness when developing a PBT final document.

The textile industry is resource-intensive, which has a significant impact on global emissions and waste pollution. To meet the demand of textiles over a third of fibres used in manufacturing are sourced from fossil fuels. As the global demand for textiles continues to grow, manufacturers are having to seek innovative approaches to providing sustainable and regenerative cellulose fibres. However, the latest climate change pressures on the textile industry have uncovered grave environmental issues associated with traditional regenerative cellulose production, such as the viscose manufacturing process. The viscose process requires intensive use of hazardous chemicals which leads to water pollution and ecotoxicity. In addition, if forestry products are unsustainably sourced for this process, this can lead to resource scarcity and deforestation. To provide a holistic solution for mitigating these challenges this study uses the by-products of paper manufacturing dissolved in an ionic liquid to produce regenerated cellulose filaments. Paper mill sludge (PMS) is a cellulosic by-product typically used on animal bedding and land spreading. The material has been dissolved in an ionic liquid - 1-ethyl-3-methylimidazolium diethyl phosphate - with the aid of a co-solvent dimethyl sulfoxide (DMSO) - and spun into continuous filaments for textile production. The mechanical properties of paper sludge filaments are found to be competitive with commercial viscose, which is promising for their drop-in replacement. It is also demonstrated that by increasing the concentration of the PMS from 9% to 12.4%, an improvement of the filament properties can be achieved; an increase in modulus from ∼19 GPa to ∼26 GPa and strength from ∼223 MPa to ∼282 MPa. These values are shown to be competitive with other commercial, less sustainable, regenerated cellulose fibres.

The recycled paper industry produces tons of waste whose disposal is a cost for industry and the environment. This research examines the suitability of de-inked paper sludge (DPS), after pelletization, as a sustainable alternative component to a peat-based growing media, creating ideal root conditions for tree development (e.g. high water storage, low compaction). DPS, tested on Lepidium sativum L. germination, did not show toxicity effects. Three species, Quercus ilex L., Lagerstroemia indica L. and Prunus serrulata “Kanzan”, were planted in 40 cm O pots filled with a control (peat, pumice and zeolite) and the experimental substrate (compost, DPS pellets, pumice and zeolite). After two years in the nursery, the trees were planted in situ. The physical and chemical properties of substrates were analyzed. Plant morphological and physiological parameters were monitored: trunk diameter, leaf dry matter, leaf nitrogen, chlorophyll, and photosynthetic efficiency. The new substrate showed higher Corg (+135%), total N (+73%) and easily available water (+19%), compared to the control substrate used in the nursery. In this new substrate, the trees showed similar radial growth values to the control in the nursery and after transplanting in situ improved their photosynthetic performance in terms of quantum yield of photosystem II (+36%, and +29% in P. serrulata and L. indica, respectively) and electron transport rate (+39%, +25%, and +32% in P. serrulata, Q. ilex and L. indica, respectively). Pelletization represents an attractive amendment for growing media, which enhances the plant’s physiological health status. This study proposes alternative recovery methods for paper industry waste with low environmental impact. As the process is developed locally, it should also contribute to reducing energy-related CO2 emissions from transport. Pelletization represents an attractive novelty in the use of DPS as amendment for growing media, which enhances the plant’s physiological health status. This study proposes alternative recovery methods for paper industry waste with low environmental impact. As the process is developed locally, it should also contribute to reducing energy-related CO2 emissions from transport.

There is a growing interest in the health professionals’ performance sustenance and work- related attitudes research. This is primarily because health professionals experience on daily basis some undesirable variables like fatigue, `well-being, stress, emotional drain, psychological need frustration and job dissatisfaction which affect performance and its sustenance. Health managers quest to resolve issues of performance sustenance, have resulted in difficulties in their attempt to motivate health professionals to be highly functional and effective to sustain performance. In a lower-middle income country like Ghana, there has not been a lot of success in this regard considering the enormity of psychological challenges and the seemingly disturbing work environment health professionals engage their services in. These continue to affect performance fundamentally because they keep experiencing negative development psychologically. Additionally, it has been documented severally in the extant literature how these negative psychological developments affect the performance of healthcare professionals which unreservedly requires a new dimension in the way work environment is managed. A gap our study intends to address through the incorporation of positive psychological capital which we seek to use in moderating the work related attitudes that has the capacity to address the negativity that has engulfed work environment among healthcare professionals.

Unprinting of paper can reduce multiple life-cycle stages in the recycling of paper to yield significant environmental impact. Laser-unprinting has been demonstrated for uncoated paper but causes significant damage to coated paper. This work explores a scalable optical (non-laser) process for unprinting coated paper. Printed coated paper is exposed to pulsed broad-spectrum Intense Pulsed Light (IPL) from a xenon lamp and the toner is then removed by dabbing gently with an ethanol wipe. While black toner is easily unprinted, unprinting of colored prints (red, blue, green) is best realized by incorporating an initial overprint of black toner. An unprinting throughput on the order of mm2/s is achieved. Three distinct regimes of unprinting are identified based on the extent of toner removal and damage of the paper. The optical properties of the unprinted paper, characterized via UV–Visible spectrophotometry, are correlated to these regimes to understand the potential for in-situ optical process monitoring. Scanning Electron Micrography and Fourier-Transform Infrared Spectroscopy are performed to understand the underlying mechanisms that govern the occurrence of the different unprinting regimes. Further, the potential impact of the developed approach on recycling of paper is discussed in the context of the capabilities of current optical unprinting approaches and the potential elimination of life-cycle stages in conventional paper recycling.

The hypothesis of this paper is that writers with similar academic backgrounds express personal attitudes in English and in Spanish differently in research papers. Thus, the main objectives are, first, to study the differences in the use of attitude devices in Spanish and English academic discourse; second, to compare the results in the different sections of articles; and finally to study the positive or negative semantic implications of the lexical items by carrying out a sentiment analysis. To this end, fifteen Spanish industrial engineering papers were compared with fifteen English industrial engineering papers. The results showed that there are in fact differences in the way academic writers communicate attitude, but the sentiment analysis revealed that neutral lexical items were the most commonly used in engineering research papers. Even though engineering researchers share the knowledge of the specialist content and the academic style of expressing their thoughts, personal attitudes were expressed in different ways in Spanish and in English.

In 2015 Ross Gibson wrote about the need in the academy for “linguistic explication” of the artwork and creative process, in particular to encourage debate on knowledge that arises from the work. I began my creative practice PhD after spending twenty years as a successful documentary practitioner. When it was time to start writing about my research and the new knowledge, instead of using text I turned to the audiovisual medium as my method of communication. I created “Filming” (2017), which combines the theory-rich mode of academic papers with the audio-visual form of my art, documentary. I called it a “digital paper”. The digital paper form has become an integral part of my PhD. This hybrid creative practice uses my artform medium as my method of communicating Gibson’s “linguistic explication”, rather than using text alone. This report will locate the digital paper within my PhD practice.

Industrialization and urbanization are the key drivers to threaten the environmental quality and natural resources. Traditionally, pulp and paper industry has been highly reliant on forest based resources for its escalation. Shortage of forest based raw materials, strict environmental regulations and policies have compelled the industry to seek for alternate raw materials for its production. Mills are now focusing on exploring the potential of different agro wastes such as cereal straws and bagasse etc. In present research, sugarcane trash, one of the most abundant agro residues in India, was investigated for its capability in pulping and bleaching. Chemical characterization of sugarcane trash showed that it contains 40.4% cellulose, 33.2% hemicelluloses, 17.4% lignin and 6.45% ash content with 2.76% silica. To cook sugarcane trash with soda pulping method, 14% alkali charge, 15 min time and 162 °C temperature was found to be optimum and pulp of kappa no. 19.8 was prepared that exhibited good strength properties. Bleaching of pulp was carried out using elemental chlorine (Cl2), hypochlorite and chlorine dioxide (ClO2) based sequences. Replacement of Cl2 with ClO2 has significant impact on strength properties and effluent characteristics. Oxygen delignification stage was incorporated prior to ClO2 that resulted in improved optical properties of pulp with noticeable reduction in wastewater load. This paper elaborates the need of using sugarcane trash in paper mills with environment friendly pulping and bleaching processes to combat with the problem of waste management, wastewater load reduction during bleaching and substitute for wood based raw materials in papermaking.

This paper examines the mechanical properties and durability of recycled aggregate concrete (RAC) containing 100% coarse recycled concrete aggregate (RCA) and industrial by-products. The by-products, including waste paper sludge ash (PSA), fly ash (FA), silica fume (SF), and metakaolin (MK) of different proportions (5%, 10%, 15%) in RAC, were used in two methods: replacement and addition methods. The use of by-products (mineral admixtures) to mitigate the low quality of RAC was demonstrated through experimental outcomes in this study. The addition of industrial by-products was presented as a promising alternative for the addition of more Portland cement in RAC to enhance RAC's quality. The results showed that the strength and durability of RAC containing mineral admixtures in the addition method were higher than the addition of more cement or the replacement method. Notably, PSA considerably improved the mechanical properties of RAC at an early age, and it substantially improved the resistance of RAC to acid and sulfate attacks. At 90 days, FA and MK improved mechanical properties of RAC greater than SF and PSA did. Among combinations, the proportions of by-products in RAC of 5% PSA, 10% SF, 15% MK and 15% FA can produce the highest performance of RAC with 100% coarse recycled concrete aggregate (RCA).

Pulp and paper industry is one of the high priority sectors that generates large amount of solid (sludge) and liquid (paper mill effluent) wastes. Making use of this huge quantity of paper mill sludge (PMS) in an environment friendly manner is challenging and cost involving. Similarly the present wastewater treatment strategies based on physical and chemical methods encounter certain serious setbacks including secondary pollution generation with expensive mode of abatement processes. The present study aims at a “waste treats waste” strategy for the bioremediation of paper mill effluent in fluidized bed reactor (FBR) using another waste of the same industry, PMS as immobilizing matrix for Planococcus sp. TRC1, a wastewater bacterial isolate. This study simultaneously explores this isolate for the yellowish orange pigment it produces (2.3 ± 0.2 mg/gm of dry bacterial biomass) and characterizes it as a member of the pharmacologically important carotenoid pigment family via UV-Vis spectrophotometry, TLC, FT-IR and 13C NMR. The antioxidant potential of this pigment was studied by DPPH assay (IC50 = 33 ± 0.4 μg/ml) and H2O2 assay (IC50 = 147.4 ± 2.2 μg/ml). In FBR, the PMS immobilized bacteria showed removal of phenol, lignin, colour and COD from the effluent by 96%, 74%, 81% and 85% respectively after 60hr of treatment. The experimental data on immobilization fitted well with pseudo second-order (R2 = 0.955) and Freundlich adsorption isotherm (R2 = 0.996) models. The alterations in PMS before and after bacterial immobilization, as revealed by SEM and FT-IR, depicted the success of PMS as immobilization matrix. Phytotoxicity (90% seed germination) and mutagenicity studies confirmed that the treated effluent was substantially less toxic than its raw state. This study highlights a novel utilization possibility of PMS in an eco-friendly and economic way as immobilization matrix for Planococcus sp.TRC1 for paper pulp mill effluent treatment along with production of carotenoid pigment from this potential bacterial isolate as value added product.

PurposeStatistical charts are an essential source of information in academic papers. Charts have an important role in conveying, clarifying and simplifying the research results provided by the authors, but they present some accessibility barriers for people with low vision. This article aims to evaluate the accessibility of the statistical charts published in the library and information science (LIS) journals with the greatest impact factor.Design/methodology/approachA list of heuristic indicators developed by the authors has been used to assess the accessibility of statistical charts for people with low vision. The heuristics have been applied to a sample of charts from 2019 issues of ten LIS journals with the highest impact factor according to the ranking of the JCR.FindingsThe current practices of image submission do not follow the basic recommended guidelines on accessibility like color contrast or the use of textual alternatives. On the other hand, some incongruities between the technical suggestions of image submission and their application in analyzed charts also emerged. The main problems identified are: poor text alternatives, insufficient contrast ratio between adjacent colors and the inexistence of customization options. Authoring tools do not help authors to fulfill these requirements.Research limitations/implicationsThe sample is not very extensive; nonetheless, it is representative of common practices and the most frequent accessibility problems in this context.Social implicationsThe heuristics proposed are a good starting point to generate guidelines for authors when preparing their papers for publication and to guide journal publishers in creating accessible documents. Low-vision users, a highly prevalent condition, will benefit from the improvements.Originality/valueThe results of this research provide key insights into low-vision accessibility barriers, not considered in previous literature and can be a starting point for their solution.

This paper presents a methodological proposal based on the identification of highly cited papers (HCPs) at domestic-level in the Spanish Public University System (SUPE), in order to find the most outstanding publications in the local context. The principal aim is to detect different activity and impact profiles among Spanish universities and differentiate those institutions that play a more significant role. To determine which and how many are the highly cited papers at the domestic level (HCP-DL) collected in the Web of Science, three citation thresholds (1, 5, and 10%) were established. Thematic classification in Incites/Essential Science Indicators areas is used. The results show a preponderance of HCPs in the field of Space Science, while the polytechnic universities have high visibility in the Computer Science area. It has been observed that the presence of HCPs in a given area is involved with universities specialized in teaching and research activities. In absolute terms, the big non-specialized universities are major producers of HCPs and hold the leading positions in our results. However, when efficiency is analyzed in relative terms, some small, specialized universities reveal themselves to be more efficient at producing HCPs (% of HCPs or citations per HCP). We think that this methodology, due to its simplicity, its ease of calculation, and the knowledge it provides, can be very useful to analyze the national systems of any country, in order to know the impact and visibility of the research carried out in its scientific institutions or research areas.

Panic buying of toilet rolls in Australia began in early March 2020. This was related to the realisation that the novel coronavirus was spreading across the country. To the general population the impact of the virus was unknown. Gradually the federal government started closing the country’s borders. The panic buying of toilet rolls was not unique to Australia. It happened across all societies that used toilet paper rather than water to clean after defecation and urination. However, research suggests that the panic buying was most extreme in Australia. This article argues that the panic buying was closely linked to everyday notions of Western civilisation. Pedestal toilets and toilet paper are key aspects of civilisation and the fear of the loss of toilet paper is connected to anxiety about social breakdown, the loss of civilisation. This is the fear manifested in the perceived threat posed by the virus. Refereed/Peer-reviewed

The social paper wasp Agelaia pallipes is known to eat carrion and scavenge on vertebrates. There are few records of wasps predating vertebrates, including an attack on an adult hummingbird and the predation of bird nestlings. During a project monitoring reproductive behaviour of a neotropical songbird, the Lined Seedeater Sporophila lineola in south-eastern Brazil, we recorded the predation of a four-day-old nestling by a social paper wasp. In the video, the adult female bird attempted to visit the nest prior to the predation. The male could be seen with its crest feathers erect after a wasp left the nest, when the nestling was presumably already dead. When we arrived at the nest to remove the camera, we found the nestling dead, and did not observe the parents in the vicinity. We also registered two other dead nestlings in a different nest with similar wounds. However, the conclusive cause of death of those nestlings is unknown. Nest predation is a major selective pressure in birds, and insects are rarely assumed to play a notable role in this process. Further research is needed to better understand the nature of the relationship between wasps and birds.

While the use of blogs has gained increasing popularity among second language (L2) writers, research into their role in developing L2 writing ability is yet underdeveloped. In particular, investigations into the use and effectiveness of peer feedback on L2 blogs are limited. The current study sought to fill this gap by comparing the provision of peer feedback in blogs versus on paper. Participants were a class of ESL students in a TESL university program in Quebec who produced written texts both in blogs and on paper, received peer feedback, and then revised their texts. Altogether, the findings suggest that while both blogs and paper can be influential mediums for L2 writing, they may inspire different types of errors, elicit different types and degrees of feedback, and lead to differences in subsequent revisions.

The World Association for Infant Mental Health (WAIMH) decided to compose a position paper on infants' rights in wartime, as there is still a general lack of attention paid to the impact of war-related traumas on infants' development and psychological health. Though there are numerous areas of violent conflicts around the globe, there have been few published studies that relate specifically to infants. Consequently, humanitarian aid programs tend to overlook infants' psychological needs and to pay more attention to those of older children. This position paper first reviews the studies identified through a literature search, about the impact of war-related traumas during pregnancy and postnatal periods, then describes the existing recommendations that have been added to the Children Rights Convention and their implications for infant mental health clinicians.
