Background The screening of biological hazards, chemical contaminants and allergens in food products is a major concern of food industry since they can cause serious illnesses and even lead to death. Therefore, there is a significant interest in developing low-cost, robust, and rapid detection methods for food safety and quality analysis. Conventional methods provide accurate analytical characteristics, but require well-equipped laboratories, trained personnel, costly reagents, and complicated sample preparation procedures prior to the detection in order to obtain reliable results. Hence, they are not always ideal for on-site food surveillance. Scope and approach This paper discusses the fundamentals of microfluidic paper-based analytical devices (μPADs) and reviews the recent progress in their usage for screening biological hazards, harmful chemical residues, and allergens in food products to systematically evaluate the strengths and weaknesses of this technology. It then covers future trends and useful strategies that could be employed in μPADs design and fabrication procedures to address the critical challenges in equipment-free food analysis. Key findings and conclusions μPADs offer promising avenues to revolutionize food safety and quality analysis with merits of equipment-free sample preparation and detection at low-cost. Despite the advancement in the microfluidic technology, the manufacturing of user-friendly sample-to-answer μPADs still requires intensive research studies to be employed for robust and sensitive food safety and quality analysis.

The construction industry had approached a critical limit which led to the increase of cement production. The production of cement would cause a broader environmental implication. Cement production is a major source of carbon dioxide emission. Carbon dioxide gas contributes about 63.33% of global warming since the production of one ton of cement would emit about one ton of carbon dioxide to the environment. To mitigate this issue, the research community has investigated the use of waste materials that possess similar chemical properties with cement content as a material for partial cement replacement. The use of rice husk ash has shown to be a contending candidate in the literature. Therefore, this paper attempts at reviewing the performance of rice husk ash as partial cement replacement. It could be observed from the literature that concrete with 5% up to 15% of rice husk ash showed an equivalent performance to ordinary concrete in compressive, flexural, and tensile strength. Thus, rice husk ash can be used as a material replacement in concrete and reduces pollution that originates from cement production and open burning of rice husk.

Palliative radiation therapy (pRT) is an effective tool for people with incurable cancer, in the treatment of many cancer-related symptoms such as pain, bleeding and dyspnea. As utilization rates for palliative radiation therapy increase, the demands on the healthcare system continue to grow. Radiation Therapists with advanced knowledge, skills and judgements began demonstrating their ability to practice autonomously in 2004, with the development of the Clinical Specialist Radiation Therapist (CSRT) role. Since this time, CSRTs with a specific focus in pRT (pCSRT) have been increasing in both numbers as well as their positive effects on the cancer care system. Integrating a pCSRT into the existing pRT system has resulted in increased access to and quality of pRT being delivered to palliative cancer patients. The benefits of the addition of pCSRTs to the cancer care system include increasing system capacity and increasing quality of care. This white paper provides information related to the improvements that can be realized in a RT program related to the care and treatment of its palliative patients by adding a pCSRT to the interprofessional healthcare team and suggest it as one of many strategies that can be undertaken to make improvements to access and quality of care.

This article discusses Freud’s presentation on telepathy to his close colleagues at the meeting in the Harz mountains in 1921. It considers the fate of his paper and the reasons why he never published it as a single piece. The development of Freud’s ideas about telepathy during the succeeding years and the reasons that prompted him finally to publish his views on thought-transference in 1925 are also considered. The article also discusses the place of the four cases presented in his writings on telepathy over this period, culminating in his new ‘lecture’ on Dreams and Occultism in 1933. It is suggested that Freud’s persuasion that psychoanalysis could credibly account for thought-transference was in part affected by the degree of trust he held in those presenting him with material, but most of all by his own personal experience. Freud held out against opposition from people like Jones on the matter of the worthiness of the subject for investigation, but never succeeded in integrating it more fully into psychoanalysis, and this position is largely unchanged today.

The global reality of the COVID-19/Corona pandemic paradoxically boosted national politics, broadcasting and citizenship. Media coverage, especially initially, praised citizen solidarity and the creative solutions that were pioneered to care for each other. A year later, a lasting social learning curve throughout and after this crisis seems illusory. The pandemic, this paper argues, needs to be understood in a longer timeframe as the working through and coming to terms with neo-liberal governmentality. The (often hilarious) early responses on social media provide a strong entry to do so. Our focus will be on the Netherlands which had a so-called ‘intelligent’ lockdown during the first wave of COVID-19 in the spring of 2020. Using the authors’ own sharing back and forth of toilet paper memes as a starting point, we aim to explore the notion of collective self-reflection and citizen co-education underlying both heated and simply ridiculous posts. Using previous discussion of cultural citizenship, this paper inquires into how pandemic citizenship played out as a vast exercise in disciplining and distinction through jokes and anger. The material suggests a nostalgic turn that might point to an implicitly voiced critique of neoliberal governmentality.

Recent decades have witnessed increasing interest in the concept of the circular economy within both the business world and political circles. The circular economy spans the entire life cycle of products from product design through production, marketing, and consumption, to waste management, recycling, and re-use, and enthusiasm for putting the concept into practice has been identified across different sectors of the economy. This exploratory case study reviews how some of the leading companies in the paper and retail industries, have publicly addressed the circular economy. The case study outlines the nature of the circular economy, provides a cameo literature review of published work on the circular economy, describes the approach adopted for the case study, reports the findings of the review of how the leading companies in the paper and retail industries have addressed the circular economy, and discusses some wider issues. Keywords: circular economy, case study, paper industry, retail industry, greenwash, economic growth

Illicit drug use causes over half a million deaths worldwide every year. Drugs of abuse are commonly smuggled through customs and border checkpoints and, increasingly, through parcel delivery services. Improved methods for detection of trace drug residues from surfaces are needed. Such methods should be robust, fieldable, sensitive, and capable of detecting a wide range of drugs. In this work, commercially produced paper with a pressure-sensitive adhesive coating was utilized for the collection and analysis of trace drug residues by paper spray mass spectrometry (MS). This modified substrate was used to combine sample collection of drug residues from surfaces with rapid detection using a single paper spray ticket. The all-in-one ticket was used to probe different surfaces commonly encountered in forensic work including clothing, cardboard, glass, concrete, asphalt, and aluminum. A total of 10 drugs (acetyl fentanyl, fentanyl, clonazolam, cocaine, heroin, ketamine, methamphetamine, methylone, U-47700, and XLR-11) were evaluated and found to be detectable in the picogram range using a benchtop mass spectrometer and in the low nanogram range using a portable ion trap MS. The novel approach demonstrates a simple yet effective sampling strategy, allowing for rapid identification from difficult surfaces via paper spray mass spectrometry.

The study attempted to assess the water quality around paper mill effluents discharge areas. Several physicochemical parameters and the Canadian Council of Ministers of the Environment (CCME) Water Quality Index (WQI) were considered to determine the pollution level of surface and groundwater in the selected paper mills areas located in Saidpur, Gobindaganj, and Dupchanchia Upazilas of Bangladesh. Physicochemical characterization of the surface water around the paper mills areas showed that the concentration of EC, TSS, BOD5, COD, phenols, NO3−-N, and K+were exceeded the surface water standard, whereas the DO level ranged from 1.63 to 3.5 were found below the Environmental Conservation Rules (ECR), 1997 standard. Besides, the BOD, COD, and Mn ion concentrations of groundwater exceeded the drinking water standard. In most sampling sites, the WQI of the surface water showed ‘marginal’ category, and the groundwater quality showed 'fair' category. The study observed that the toxic effluents discharged from the paper mills caused harm to the aquatic ecosystem.

Chemotherapeutic drugs have been widely used in the treatment of cancer disease for about 70 years. The development of new treatments has not hindered their use, and oncologists still prescribe them routinely, alone or in combination with other antineoplastic agents. However, all chemotherapeutic agents can induce hypersensitivity reactions (HSRs), with different incidences depending on the culprit drug. These reactions are the third leading cause of fatal drug-induced anaphylaxis in the United States. In Europe, deaths related to chemotherapy have also been reported. In particular, most reactions are caused by platinum compounds, taxanes, epipodophyllotoxins and asparaginase. Despite their prevalence and relevance, the ideal pathways for diagnosis, treatment and prevention of these reactions are still unclear, and practice remains considerably heterogeneous with vast differences from center to center. Thus, the European Network on Drug Allergy and Drug Allergy Interest Group of the European Academy of Allergy and Clinical Immunology organized a task force to provide data and recommendations regarding the allergological work-up in this field of drug hypersensitivity reactions. This position paper aims to provide consensus on the investigation of HSRs to chemotherapeutic drugs and give practical recommendations for clinicians that treat these patients, such as oncologists, allergologists and internists. Key sections cover risk factors, pathogenesis, symptoms, the role of skin tests, in vitro tests, indications and contraindications of drug provocation tests and desensitization of neoplastic patients with allergic reactions to chemotherapeutic drugs. Statements, recommendations and unmet needs were discussed and proposed at the end of each section.

European pharmaceutical companies have a legal requirement to provide non-promotional Medical Information (MI) services to support healthcare professionals (HCPs) who are using their medicinal products. While the industry has self-regulating bodies with established Codes of Practice, these mainly focus on promotional messaging and commercial activities. In the absence of similar frameworks for MI, such services struggle to understand how to meet HCP digital expectations, often in fear of breaching the promotional codes. This is limiting access to the wealth of non-promotional patient-focussed information held within the industry. Meanwhile, a large volume of unregulated, low-quality information can be readily found on the internet. To understand the current status, the Medical Information Leaders in Europe (MILE) industry association performed a benchmarking survey which explored the online MI service provision of 13 mid-large pharmaceutical companies across Europe. This highlighted a great diversity in approach in terms of geographical coverage and content. Visibility and access for HCPs is complex, compromising online engagement and website utilisation. This MILE position paper highlights the critical need to establish a clear governance model, which empowers pharmaceutical company MI functions to provide unbranded, non-promotional, medicinal product information sources to support HCP online information needs. It is essential to build confidence, transparency and trust by establishing a practical quality framework with principles and standards for online MI services for HCPs.

Synthetic cannabinoid receptor agonists (SCRAs) are a class of varied compounds that mimic the effects of natural cannabinoids found in cannabis. Because they have a wide range of diverse structures, they vary widely in their potency. The abuse of new psychoactive substances (NPS) in prisons was reported in many European countries and in the USA. In the present study, we have described the identification of SCRAs in 56 infused paper sheet samples, seized mainly in Brazilian prisons between 2016 and 2020. The materials were seized by local or federal law enforcement and analyzed by Sao Paulo State Police or Brazilian Federal Police using gas chromatography–mass spectrometry, attenuated total reflection-Fourier transform infrared spectroscopy, liquid chromatography–high-resolution mass spectrometry or nuclear magnetic resonance spectrometry. Most of these samples (87.5%) were seized in 2019–2020; seven different SCRAs were identified in samples, and the most frequently identified substances were MDMB-4en-PINACA (23.6%) and 5F-MDMB-PICA (36.4%), the newest SCRAs emerging recently. As observed in Europe and the USA, Brazil also shows the prevalence of indazole-3-carboxamides and indole-3-carboxamides among SCRAs seizures in the prison system. This phenomenon is spreading all over the world at this moment. These data on the prevalence could help to alert judicial authorities to shutting down the introduction of NPS, including SCRAs, into prisons to ensure safety and security for avoiding health risks of prisoners and staff, leading to positive effects in this population. To our knowledge, this is the first demonstration of SCRAs smuggling into prisons in Latin America.

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.

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.

Virgin pulp is made by splitting up cellulose fibers from the woods by mechanical and chemical process without adding any recycled pulp content. The demand for trees, which are the basic raw material for making virgin pulp, increasing constantly in enormously growing paper manufacturing industry. The paper, which is made from virgin pulp is called as virgin paper and this is considered as better quality paper than the recycled paper. Now there is a need to increase the quality of recycled paper to equalize the quality of virgin paper, to reduce the demand for trees to make virgin pulp. In recycling, dispersive system is responsible for the de-inking process, which is one of the pulp purifying process which removes the printing ink from fibers. Chemicals are added in this deinking process which causes a serious problem by increasing the chemical concentration level of industrial outlet water. In conventional deinking technology, dispersive system is controlled by DCS which is quite complicated to control complex loop of operations. To overcome these problems, the dispersive system operations are controlled by PLC along with sensors which make the process easier and replacing the chemicals with enzymes will reduce the chemical concentration level of industrial outlet water and increases the quality of paper.

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.

The aim of this review is to introduce the information concerning advanced technology of ink-jet printing regarding characteristics and ink-jet paper. It is believed that ink-jet paper having suitable liquid absorption characteristics and drying techniques are required to improve image quality on high-speed inkjet printing. Although the development of high quality ink-jet paper is important, the demand or the dual-purpose coated paper that can be used with offset and ink-jet printing is expected to increase for the time being. Meanwhile, it is important to get cost down and raise the productivity of the inkjet paper to secure competitiveness comparable to that of offset coated paper. For those objectives we think that the development of new technologies is required for pigment development, composition design of the coating ingredients, and rheological characteristics analysis of coating colors.

The American Society for Parenteral and Enteral Nutrition (ASPEN) Position Paper focus is on applying the 4 ethical principles for clinician's decision-making in the use of artificially administered nutrition and hydration (AANH) for adult and pediatric patients. These basic principles are (1) autonomy, respect the patient's healthcare preferences; (2) beneficence, provide healthcare in the best interest of the patient; (3) nonmaleficence, do no harm; and (4) justice, provide all individuals a fair and appropriate distribution of healthcare resources. Preventing and resolving ethical dilemmas is addressed, with an emphasis on a collaborative, interdisciplinary approach. Optimizing early communication and promoting advance care planning, involving completion of an advance directive, including designation of a surrogate decision-maker, are encouraged. Clinicians achieve respect for autonomy when they incorporate the patient, family, community, country, geographical, and presumed cultural values and religious belief considerations into ethical decision-making for adults and children with a shared decision-making process. These discussions should be guided by the 4 ethical principles. Hospital committees and teams, limited-time trials, clinician obligation with conflicts, and forgoing of AANH are addressed. Specific patient conditions are addressed because of the concern for potential ethical issues: coma, decreased consciousness, and dementia; advanced dementia; cancer; eating disorders; and end-stage disease/terminal illness. Incorporated in the Position Paper are ethical decisions during a pandemic and a legal summary involving ethical issues. International authors presented the similarities and differences within their own country or region and compared them with the US perspective.

In the today’s context of COVID-19, when a strong need of disposable items without compromising the environmental attributes is being felt, “Paper” is becoming a very mesmerizing and quintessential object. We find paper in our lives so omnipresent and enduring that we take it granted without understanding its complex nature, manufacturing/development process and the significant role, it has actually played in the history of civilization. It is so important that the Per Capita Consumption of paper for a country reflects the development status of its society. Therefore, this article attempts to introduce paper with its historical development, manufacturing process, environmental concerns, ways to address the environmental concerns, global and national status of pulp and paper industry along with the challenges ahead with a coverage of the potential role it is bound to play in future through an overall transformation of the industry itself.

Flexible paper-based sensors may be applied in numerous fields, but this requires addressing their limitations related to poor thermal and water resistance, which results in low service life. Herein, we report a paper-based composite sensor composed of carboxylic carbon nanotubes (CCNTs) and poly-m-phenyleneisophthalamide (PMIA), fabricated by a facile papermaking process. The CCNT/PMIA composite sensor exhibits an ability to detect pressures generated by various human movements, attributed to the sensor's conductive network and the characteristic "mud-brick" microstructure. The sensor exhibits the capability to monitor human motions, such as bending of finger joints and elbow joints, speaking, blinking, and smiling, as well as temperature variations in the range of 30-90 °C. Such a capability to sensitively detect pressure can be realized at different applied frequencies, gradient sagittas, and multiple twists with a short response time (104 ms) even after being soaked in water, acid, and alkali solutions. Moreover, the sensor demonstrates excellent mechanical properties and hence can be folded up to 6000 times without failure, can bear 5 kg of load without breaking, and can be cycled 2000 times without energy loss, providing a great possibility for a long sensing life. Additionally, the composite sensor shows exceptional Joule heating performance, which can reach 242 °C in less than 15 s even when powered by a low input voltage (25 V). From the perspective of industrialization, low-cost and large-scale roll-to-roll production of the paper-based sensor can be achieved, with a formed length of thousands of meters, showing great potential for future industrial applications as a wearable smart sensor for detecting pressure and temperature, with the capability of electric heating.

Human trafficking is a pandemic human rights violation with an emerging paradigm shift that reframes an issue traditionally seen through a criminal justice lens to that of a public health crisis, particularly for children. Children and adolescents who are trafficked or are at risk for trafficking should receive evidence-based, trauma-informed, and culturally responsive care from trained health care providers (HCPs). The purpose of this article was to engage and equip pediatric HCPs to respond effectively to human trafficking in the clinical setting, improving health outcomes for affected and at-risk children. Pediatric HCPs are ideally positioned to intervene and advocate for children with health disparities and vulnerability to trafficking in a broad spectrum of care settings and to optimize equitable health outcomes.

Physical paper puppets are inanimate objects, but when we’re speaking in terms of the production of traditional paper cut out animation, they become the actors and the souls that drive the movie. When shooting and animating traditional paper cut out animation, the puppets are laid flat on a surface so they can only move in limited directions compared to conventional 2D or 3D animation. As we know, each character in animated movie has its own personality and unique to each other. The challenge lays in bringing out the characteristics and personality of the character through the limited medium of paper puppet. In this qualitative research, puppet movements will be applied to quadruped cat characters in a public service announcement titled “Spay & Neuter”. The puppet along with the visual design, segmentations, and joints were done in previous research. Qualitative observations and audio-visual materials are used to collect the data for references. Literature review will study the characteristics of cats, body language, behaviour, and principles of animation especially timing and exaggeration. Observation is conducted by studying the movements of real cats from online videos and direct observations and also studying how other animators animate cat characters in animated films. In the exploration stage, paper puppets will be animated according to the movement design while experimenting with the timing and frame rate of the stop motion to achieve the final results.

The aims of this study are to investigate the problems and challenges of university students in writing English scholarly article for an international journal and to elaborate their perceptions toward the importance of writing for the publication. Furthermore, it also explores the certain needs to support their skills in the process of writing the article.The investigation involves 20 students from one of the universities in Indonesia. It uses a questionnaire consisted of 24 items to understand the students‟ problems and perceptions of the issues in relation to writing for the academic publication in English. The findings of this study indicate that claiming knowledge was the most difficult aspect in writing the article. On the other hand, students agree that writing for international publication is considered as a crucial action in academic field, and henceforth, they needs to have university‟s support to prepare students‟ writing. Finally, some suggestions related to students‟ problem in writing for international publicationare are offered.

The main purpose of the living technology curriculum is to cultivate students' interest in learning science and technology, and further to utilize their experience of learning instructions and develop their ability to integrate interdisciplinary knowledge and skills. In recent years, as countries have begun to emphasize the concept of interdisciplinary integration in the school education, STEM (Science, Technology, Engineering, and Mathematics, STEM) focuses on cultivating interdisciplinary talents. With this, STEAM highlights the role of ART because other dimensions of STEM are expected to be effectively integrated through the cultivation of aesthetics; the purpose of this study is to design a STEAM curriculum for elementary school children and to explore the impact of STEAM education on the creativity. The content of this course is based on the PBL (Project-Based Learning) with the teaching activities combining with “Chinese Paper-cutting” and “BBC micro: bit”. The teaching process is used the strategy of creative thinking instruction. The research method adopts a one-group pretest–posttest design based on a purposive sampling of 21 students from one class in an elementary school. The research tools included the records of learning feedback and the creativity assessment. The empirical findings show that the project-based learning incorporating STEAM activity has a positive significant influence on students’ development of creative recognition. Since the empirical results are constricted by the short-term STEAM course, the STEAM course with the art-oriented still benefits the STEAM education and Learning effectiveness of elementary school students. The implication of interdisciplinary interactive Lamp of Paper Carving with Micro:Bit is expected to contribute to further development of STEAM course. Since the curriculum is only last for few weeks, it is too short to affect the emotional facet of creativity. Future researches are suggested to extend the teaching period and evaluate the long-term influence of PBL STEAM on students' learning attitude.

Perinatal depression can have enduring adverse effects on women and their children and families, incurring substantial ongoing economic and personal costs. A significant proportion of the cost of perinatal depression relates to adverse impacts on the child, most likely mediated through impairment to the mother-infant relationship. In recognition of this problem, Australia has invested in routine perinatal depression screening. Our previous research produced convergent findings suggesting that expected benefits for children have not yet been realised through perinatal depression screening. We question the potential of including a measure of personality in current perinatal depression screening for identifying maternal mental health problems and suboptimal mother-infant relationships. This paper reviews our previous research findings within the broader context of perinatal depression screening. We propose a position, that perinatal depression screening in Australia should be redesigned to more precisely detect vulnerable mother-infant relationships, parenting, maternal mental health, and infant psychosocial and psychological development. Practice change to appropriately target antenatal interventions may more efficiently improve both maternal and child outcomes, thereby contributing to greater efficiency and cost savings for the health system.

This study was carried out in an attempt to evaluate the impact of Broussonetia papyrifera as a roughage substitute at different levels on carcase traits, growth performance, meat quality and immune performance in Hu ram lambs. Sixty Hu rams (5 months of age, 26.70 ± 2.14 kg body weight) were randomly divided into four groups. The treatments comprised B. papyrifera supplementation at levels of 0% (G0), 30% (G30), 60% (G60) and 100% (G100) of roughage feed. The results suggested that diet supplemented with B. papyrifera (G100 group) caused a higher average weight gain (AWG) and average daily gain (ADG) than those of G0 group. The highest carcase weight was observed in the G60 group. The chemical and physical properties of the longissimus dorsi muscle of Hu rams showed no significant differences (p>.05). For fatty acid, the G60 group had significantly lower content of saturated fatty acids (SFAs), higher contents of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) and higher PUFA/SFA ratio than other groups (p

Objective This study collected randomized controlled trials (RCTs) published in the social sciences in China and assessed their risk of bias and reporting quality. Study Design and Setting Three databases were systematically searched for publications from January 2000 to June 2020 for RCTs in the social sciences published by Chinese researchers. The risk of bias was assessed using the Cochrane Collaboration Risk of Bias Tool (CCRBT), and reporting quality was assessed using the Consolidated Standards of Reporting Trials for Social and Psychological Interventions (CONSORT-SPI). Results A total of 316 RCTs were identified, including 204 articles in English and 112 articles in Chinese. The most frequently researched interventions focused on education (33.9%), and the most frequently studied population were students (32.9%). Eighty-seven percent of RCTs had intermediate reporting quality. Twenty-four of the 43 CONSORT-SPI sub-items had a compliance rate of less than 50%. Most RCTs had an unclear risk of bias for blinding outcome assessors (84.5%), blinding participants and personnel (82.9%), allocation concealment (73.1%), and random sequence generation (68.0%). A low proportion of CONSORT-SPI items were reported and, high proportion of the papers had unclear risk of bias. Conclusion The quality and reporting of RCTs in the social sciences needs improvement in China, especially for reporting methods and results. Most studies had an unclear risk of bias as they lacked important methodological information.

The article examines Soviet paper reuse as an ideological, economic daily practice, implemented through the advanced, but hitherto undescribed Soiuzutil’ waste collecting system by the early 1930s as the reverse side of Stalinist industrialization. It argues that Soiuzutil’ waste paper handling attempted to form a new socialist collective by reworking old print while cultivating citizens as classless scrap-collectors, for the sake of an (ir)rational resource optimization. While World War II intensified recycling efforts among the Allied and Axis powers, invasion and evacuation damaged Soviet waste collection to a point where no return of paper into a centralized system was possible. War forced printers and consumers to retreat to local self-supply networks, as paper remained a crucial, yet scarce resource. By analyzing technical-educational literature and correspondence of the reutilization offices, the article demonstrates the changing attitudes in the Stalinist war economy, the industries, and the population towards mobilizing and saving paper.

The efficiency of xylano-pectinolytic enzymes, co-produced by a single microbial strain Bacillus pumilus, was analysed for the recycling of mixed office waste paper through deinking and compared with the alkaline chemical deinking method. Enzymes showed maximum deinking at pH 8.5, pulp consistency of 10%, xylanase-pectinase dose of 12 and 4 IU per gram pulp, respectively, after 120 min of deinking period, and temperature at 50 °C. A chemi-enzymatic approach was employed with xylano-pectinolytic enzymes and various concentrations of deinking chemicals, which showed that enzyme-treated mixed office waste pulp requires only 40% chemicals for deinking, in order to get the almost same level of various handsheets properties, as obtained by the chemical method with 100% chemicals. Similarly, the effluent load of BOD and COD contents was also decreased by 17.90 and 19.75%. This combinational approach of deinking significantly improved the various properties of the handsheets and resulted in gain of 7.5, 9.38, 6.33 and 11.65% in tear factor, burst factor, breaking length and viscosity of the handsheets, while the effective residual ink concentration analysis of deinked handsheets of mixed office waste paper showed deinking efficiency of 22.45%, which revealed the removal of ink particles during enzymatic deinking steps.

Summary Numerous studies are published on the benefits of electric hand dryers vs paper towels (PT) for drying hands after washing. Data are conflicting and lacking key variables needed to assess infection risks. We provide a rapid scoping review on hand‐drying methods relative to hygiene and health risks. Controlled vocabulary terms and keywords were used to search PubMed (1946–2018) and Embase (1947–2018). Multiple researchers independently screened abstracts for relevance using predetermined criteria and created a quality assessment scoring system for relative study comparisons. Of 293 papers, 23 were included in the final analysis. Five studies did not compare multiple methods; however, 2 generally favoured electric dryers (ED); 7 preferred PT; and 9 had mixed or statistically insignificant results (among these, 3 contained scenarios favourable to ED, 4 had results supporting PT, and the remaining studies had broadly conflicting results). Results were mixed among and within studies and many lacked consistent design or statistical analysis. The breadth of data does not favour one method as being more hygienic. However, some authors extended generalizable recommendations without sufficient scientific evidence. The use of tools in quantitative microbial risk assessment is suggested to evaluate health exposure potentials and risks relative to hand‐drying methods. We found no data to support any human health claims associated with hand‐drying methods. Inconclusive and conflicting results represent data gaps preventing the advancement of hand‐drying policy or practice recommendations.

Reproductive conflicts are expected in societies where nonbreeding helpers retain the ability to produce offspring. Despite potential competition from reproductively capable nestmates in social wasps, egg laying tends to be monopolised by a single or relatively few queens. Genetic studies on reproductive partitioning in Polistes paper wasps suggest high reproductive skew in the genus. Conflict is thought to be minimal due to nestmate relatedness or the possibility of inheriting a reproductive monopoly on a nest; consequently, there are inclusive fitness opportunities for nonreproductive helpers. However, most studies are limited to temperate wasp species. Given the cosmopolitan distribution of Polistes, genetic data on group conflicts are required for a broader range of tropical species to determine whether these trends apply across climatic zones. We examined female reproductive skew in the Neotropical paper wasp Polistes lanio, genotyping a selection of adults and pupae from established post-emergence nests using single-nucleotide polymorphisms (SNPs). SNP-based pedigree analyses indicate a reproductive monopoly held by a single queen, with queen replacement from natal nestmates and evidence of possible multiple mating. Relatedness between pupal offspring was high (r = 0.71). It is likely that high reproductive skew among females is a founding trait of Polistes societies, conserved among species that have spread into new environments from Indomalayan origins.

The thriving development of the paper industry leaves behind a great amount of pulp and paper mill sludge (PPMS), which constitutes a considerable source of pollution. Experts estimate that...

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

A good quality control system is important to be implemented to increase productivity and minimize defects in products. One of the quality control methods is failure mode and effect analysis (FMEA). This study uses the FMEA to identify the causes of the defects and recommend the prevention methods to overcome the causes of the defects in an Indonesian paper mill. The risk priority number (RPN) is calculated by multiplying the severity, occurrence, and detection of the failures that have been determined. Unsymmetrical and tainted products are the most dominant defects in the paper mill. An inappropriate machine setting is the cause of unsymmetrical products with the highest RPN of 343. The second highest RPN is problems with bleaching machines that caused tainted products with an RPN value of 216. This study offers suggestions to Indonesian paper mill to prevent and minimize defective products.

Paper-based works of art and documents of cultural importance kept in museums and libraries can show notorious signs of deterioration, including foxing stains, caused by fungal colonization. Some of the main chromophore agents of fungal origin that deteriorate paper and therefore affect paper cultural heritage both aesthetically and structurally are the group of pigments called melanins. Thus, knowledge of the diversity and features of fungal melanins and of the melanization pathways of fungi growing on paper is key to removing these pigments from paper-based works of cultural importance. This review provides an approach about the current knowledge of melanins synthesized by paper-colonizing fungi, their localization in the fungal structures, and their role in the deterioration of paper. This knowledge might contribute to developing new, effective, and sustainable strategies of restoration and conservation of historical documents and works of art based on paper.

The pulp and paper industry wastewater has not met the environmental uality standards set by the government so it may causes pollution to the environment; therefore, it is necessary to find a better wastewater treatment. The problem of this study is how to find the wastewater treatment alternative in order to get a more effective and efficient treatment. Fenton reagents are H 2 O 2 compounds (hydrogen peroxide) with iron catalysts and is one of the Advance Oxidations Process (AOPs) methods, which can be used as an alternative to process wastewater from the pulp and paper industry. In this study, the ratio of Fenton reagent molar concentration, temperature, and stirring time were varied, with stirring speed of 300 rpm, Fenton reagent volume of 25 mL, and pH set at 3. The visible parameters in this study were COD and TSS degradation. From this study, the best ratio of Fenton reagent is 1:2000, where this ratio can reduce the COD from 1002 mg/L to 176.05 mg/L and the TSS from 125 mg/L to 49.3 mg/L. This value has met the environmental quality standards for the pulp and paper industry set by the Indonesian government.

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.

This study aims to examine Turkish exam papers of the students, who study in the secondary school of 5th, 6th, 7th and 8th classes. The exam papers have been examined from various aspects, including the number and type of questions, the language expression and distribution of the questions, the cognitive level (according to the Bloom’s taxonomy), the type of texts used, and the visuals use. The samples of the study were selected using convenience sampling method from 17 secondary schools located in the center of Ağrı Province in Turkey and the exam papers prepared by 36 Turkish teachers who worked at these schools. The tests which were examined included 2633 questions in 161 exam papers. We also developed “the Exam Paper Examination Form” for collecting more data which we analyzed and interpreted by using the document analysis model. According to the results obtained, it has been found that the teachers mostly prefer to use the multiple-choice question type in the Turkish exam papers; the questions are mostly related to grammar and reading; the teachers do not prefer to ask questions on speaking and listening; and except for spelling errors no deficiency is detected in the language of the exam papers. In addition, according to Bloom’s taxonomy, the questions are mostly at the comprehension level whereas questions related to the analyzing, evaluating and creating levels that require high level thinking skills are rarely used. Based on the results, suggestions have been presented for Turkish teachers to prepare exams.

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.

Creation of new digital technologies let automate the reproduction of text and graphic information, led to the creation and development of the digital printing. Digital printing is a technology for producing prints in the printer based on the original layout, created as corresponding codes with a computer. One of the technologies of digital printing is a computer-to-press and one of the devices in this direction is risograph. The risograph printing quality is worse than offset printing. The text is printing with medium sharpness and images remind photos in old newspapers and require special preparation. But risograph is the most profitable solution for small and medium circulations from 50 up to 1000 sheets. Wide usage of risograph printing in typographies demands increase performance of the equipment with the high print quality of digital images. To improve the quality of risographic printing, the creation of methods is required to form the initial indicators of the original layout (clarity, correct transmission of halftones, contrast). At the same time, the result of obtaining high-quality images obtained by printing on a risograph is affected by surface microgeometry and the physical and mechanical properties of paper. So, the optical density of the ink layer on the print is largely determined by the structure of the sections of paper, in particular, absorbency and porosity. To obtain high-quality images on prints, it is necessary not only to customize the original layout, but also to select paper with such characteristics that would allow you to get the best result when printing on a risograph. Since the risograph occupies an intermediate place in quality between copying equipment and laser printing, a laser print is taken as the standard for print quality. And one of the tasks of the quality of risographic prints is to increase it to the quality of laser printing.

Background: Although some have noted that combining technical and marketing content is precarious, technical communication professionals are increasingly involved in content marketing, which includes the creation of white papers. Literature review: The little existing literature on white papers provides conflicting guidance about managing the combination of technical and marketing content. Both soft-sell and hard-sell marketing approaches have been recommended. One source of such inconsistent guidance may be the lack of agreement about definitions. Research on print advertisements has described hard and soft selling as multidimensional rather than binary aspects of persuasive appeals. Research question: Which dimensions of hard- and soft-sell appeals are predominant in white papers? Research methodology: To complete our descriptive study, we collected a corpus of documents labeled as white papers in TechRepublic, and then selected and trained three raters to complete a series of judgments about dimensions of persuasive appeals in the corpus. We aggregated those ratings, calculating the mean and standard deviation for the dimensions to describe their distribution across the corpus. Results/discussion: Overall, hard-sell dimensions were more prevalent than soft-sell dimensions. However, the soft-sell category of “implicitness” was also dominant. Conclusion: Our results demonstrate the value of treating hard and soft selling as multidimensional, complementary, and combinatory marketing appeals that allow, for example, a single white paper to be both “subjective” (soft sell), and “precise” (hard sell), or both “creative” (soft sell) and “informative” (hard sell).

Yenidogan, Semiha/0000-0002-1296-2392 WOS:000518368200010 Paper - ink interaction is extremely important in printing. Ideal printing outputs should be achieved with minimal ink consumption. It should not be supposed that visual printing quality will increase as the amount of ink increases. The effects of excessive ink consumption during the printing process on process sustainability, economy and environment should not be ignored. In this study, the effects of ink consumption during the printing process on printing quality parameters were mainly examined. Paper samples were printed with different amounts of ink, and the density and CIE L*a*b* values of the solid ink films were measured. The lightfastness test was applied to determine the resistance of the printed ink films to light, and the changes in their color were examined. Ideal ink amounts to reach ideal color L*a*b* values were determined and the effects of ink amount on the printing quality parameters were highlighted. Then, ink consumption was evaluated in terms of recycling, sustainability, environmental and economic effects, and recommendations were made to reduce the use of ink.

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.

An electrical tree discharge model of multilayer insulation paper was prepared, and a voltage of 20 kV was used for electrical tree cultivation and initiation tests. Based on the microscopic image information and partial discharge (PD) information during the aging of the electrical tree, the development of electrical tree discharges between layers of paper comprising epoxy resin-impregnated paper insulation was studied. The results show that, by analysing PD information such as the discharge volume phase spectrum and the discharge repetition rate phase spectrum, the development of the electrical tree branch progresses in four stages: initial, growth, stagnation, and bursting. During the growth and stagnation stages, the main discharge paths of the electrical tree are mainly formed, and there are many filamentous fibres on the path edge. During the burst stage, more branches will be formed on the electrical tree, which will cause the greatest damage to the insulation. With the extension of the electrical tree path, the discharge magnitude and discharge times also increase. There are specific discharge patterns in different growth stages of the electrical tree, and the number of discharge events in each positive half-cycle is significantly greater than that in a negative half-cycle. Combining the microscopic image information and PD information during the aging of such an electrical tree, a theoretical basis for evaluating insulation state by PD monitoring is realised. The long-chain molecules of cellulose and epoxy resin break bonds and oxidise, which decompose into a large number of free radicals, monosaccharides, and other low-molecular-weight products.
