This paper analyses the conference papers published by double first‐class universities from mainland China between 2006 and 2019. The main findings are as follows: first, the number of conference papers from different double first‐class universities varied greatly, with the annual numbers of papers in the China Proceedings of Conferences Full‐text Database (CPCD) and in the Conference Proceedings Citation Index (CPCI) fluctuating during this period. Second, most of the top 10 disciplines of the papers in the CPCD and CPCI were in the natural sciences, with only two in the social sciences. The CPCD papers and CPCI papers had some overlap in their disciplinary distributions. Third, the CPCD and CPCI papers differed little in total number, with the number of CPCI papers being slightly higher than the number of CPCD papers. With the introduction of new regulations from the Ministry of Science and Technology (MST), there will likely be an increase in the number of Chinese‐language conference papers in the future.

The apps for drawing are present in our children's life. Nevertheless, little is known about the impact of mobile technology on the freehand drawing educational activity. There are few works which are contextualised within short periods of time, with teachers who are not theirs and, in some cases, outside the children's classroom. In this paper, we are focussed on the use of technology on freehand drawing activity. Thus, we have compared the graphics produced by 4- and 5-year-old children with paper&crayon in comparison with those with tablet-finger. Children made the drawings during a planned free-drawing activity, in their ordinary classrooms, with their teachers and during five sessions. Assessment of drawings has evidenced tablet feasibility for making graphics. Nevertheless, with the passing of time, quality of graphics (tablet-finger vs paper&crayons), are nearly matched, demonstrating the low impact level technology has on this activity. In addition, if drawings are analysed specifically according to ages, results have shown that both groups have to develop adaptation strategies of visual perceptual skills and fine motor skills for the touch screen in order to obtain the same quality in the drawings made on both support types.

The properties of handmade paper used for mounting and conservation of paintings and calligraphy on paper is crucial to the quality and lifespan of such objects. Mounting papers from China, Korea, and Japan vary greatly in performance due to different papermaking methods and fibre materials. In this study, eight types of handmade paper widely used in China, Korea, and Japan were selected for comprehensive comparative analysis investigating their pH as well as optical, mechanical, and ageing properties. The study showed that traditional hanji, improved hanji, and thin Mino paper made of pure kozo fibres performed best in terms of mechanical properties. Among the additives mixed with kozo fibres, clam shell powder was identified as a substance that improves pH and stability of optical properties. Xuan paper Mianliao was found to be a suitable material for mounting hand scrolls and hanging scrolls due to its softness and ageing properties. Traditional hanji, improved hanji, and thin Mino paper are less flexible than xuan paper Mianliao and are considered more suitable for uses other than for mounting scrolls. This study will provide a reference for improving the quality of handmade paper and a theoretical basis for the selection of such papers for the conservation of paintings and calligraphy on paper.

Natural and synthetic esters are increasingly being chosen instead of mineral oil for environmental and fire safety reasons. However, their use in power transformers is limited due to insufficiently well-understood ageing processes affecting their properties and the properties of cellulosic materials impregnated with them. The research results presented in many scientific papers prove that the use of esters slows the ageing process of cellulosic materials. This article presents the results of research aimed at answering the question of whether the effect of slowing the ageing process will also occur in the case of insulation with very low initial moisture. The answer to this question will allow us to better understand the role of water in the ageing process of the transformer's insulation system. The thermal ageing process was carried out at a temperature of 150 °C in closed systems. The degree of cellulose polymerisation was taken as a measure of the degree of paper ageing. Great attention was paid to measuring the water content in both paper and electro-insulating liquids at various stages of their ageing. Furthermore, measurements of the properties of electro-insulating liquids were made, which are considered markers of ageing. The test results obtained indicate that in the case of a dry insulation system, corresponding to the initial moisture of the new units, the type of liquid used to impregnate the cellulosic material does not significantly affect its depolymerisation process. However, in the case of paper impregnated with natural esters, a lower dynamic of moisture increase in insulation was observed. [ABSTRACT FROM AUTHOR]

Simple Summary: Blood clots are formed when blood vessels are injured. They help stop bleeding and heal wounds, but can also cause serious problems if they block blood flow or break off and travel to other organs. This study investigates how blood clots differ in people with cancer compared to healthy or non-cancerous individuals. This study found that cancer patients have higher levels of histones in their blood, which make their clots stiffer and resistant to lysis. Further, clots formed in cancer patients have higher viscoelastic properties, and hence are harder to break down. These findings suggest that cancer patients have abnormal clotting properties that may increase their risk of developing thrombosis, and evaluating these properties can be helpful in detecting cancer. Background: Blood viscoelasticity and plasma protein levels can play an important role in the diagnosis and prognosis of cancer. However, the role of histones and DNA in modulating blood clot properties remains to be investigated. This study investigates the differences in blood viscoelasticity and plasma protein levels among cancer patients, individuals with other diseases, and healthy individuals. Methods: Blood samples were collected from 101 participants, including 45 cancer patients, 22 healthy individuals, and 34 individuals with other diseases. Rheological properties of clots formed in vitro by reconstituted elements of fibrinogen or plasma were analyzed with an Anton Paar Rheometer, USA. Plasma protein levels of D-dimer, TPA, EPCR, fibrinogen, and histone H3 were measured through ELISA. Blood clots were formed with or without DNA and histones (H3) by adding thrombin and calcium to plasma samples, and were evaluated for viscoelasticity, permeability, and degradation. Results: Cancer patients show higher blood viscoelasticity and plasma D-dimer levels compared to healthy individuals and individuals with other diseases. Our in vitro analysis showed that the addition of histone to the plasma results in a significant decrease in viscoelasticity and mean fiber thickness of the clot formed thereafter. In parallel studies, using plasma from patients, DNA and histones were detected in fibrin clots and were associated with less degradation by t-PA. Moreover, our results show that the presence of DNA and histones not only increases clots' permeability, but also makes them more prone to degradation. Conclusions: Plasma histones and DNA affect the structure of the clot formed and induce defective fibrinolysis. Moreover, the increased viscoelastic properties of plasma from cancer patients can be used as potential biomarkers in cancer prognosis. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to investigate associations between digital urine color and paper urine color with other urine indices to assess hydration status. Methods: Twelve male subjects (mean ± standard deviation; age, 26 ± 8 years; body mass, 57.8 ± 5.3 kg; height, 177.5 ± 8.9 cm; VO2max, 57.8 ± 5.8 ml·kg−1·min−1) performed four exercise trials in the heat. Before and following exercise trials, subjects provide urine samples. Urine samples were measured using a digital urine color chart on a portable device screen. Urine samples were also assessed with urine specific gravity (USG), urine osmolality (UOsmo), and a validated paper urine color chart. Results: There were extremely large associations found between digital urine color and paper urine color (r = 0.926, p < 0.001). Correlation coefficients showing associations with USG and UOsmo were similar between digital urine color (USG, r = 0.695, p < 0.001; UOsmo, r = 0.555, p < 0.001) and paper urine color (USG, r = 0.713, p < 0.001; UOsmo, r = 0.570, p < 0.001). Bland–Altman analysis indicated that no proportional bias was observed between digital and paper urine colors (bias, − 0.148; SD of bias, 0.492; 95% LOA, − 1.11, 0.817; p = 0.094). Conclusions: Strong associations were found between digital and paper urine colors with no proportional bias. Furthermore, the degree of associations with USG and UOsmo was similar between digital and paper urine color. These results indicate that digital urine color is a useful tool to assess hydration status and this method could be used as an alternative method to using paper urine color. [ABSTRACT FROM AUTHOR]

Background: The Integrated Palliative Care Outcome Scale (IPOS) validly and reliably measures symptoms and concerns of those receiving palliative care. Aim: To determine the equivalence of the paper version with an electronic version of the IPOS (eIPOS). Design: Multicentre randomised crossover trial (NCT03879668) with a within-subject comparison of the two modes (washout period 30 min). Setting/Participants: Convenience sample of specialist inpatient and palliative home care patients aged over 18 years with cancer and non-cancer conditions was recruited. Scores were compared using intraclass correlation coefficients (ICC), Bland-Altman plots and via a mixed-effects analysis of variance. Results: Fifty patients were randomised to complete paper-electronic (n = 24) and electronic-paper (n = 26) IPOS with median age 69 years (range 24–95), 56% male, 16% non-cancer. The ICCs showed very high concordance for the total score (ICC 0.99, 95% CI 0.98–1.00), lowest ICCs being observed for symptoms 'Appetite loss' and 'Drowsiness' (ICC 0.95, 95% CI 0.92–0.97). Nine of seventeen items had ICCs above 0.98, as did all subscales. No statistically significant mode, order, age, and interaction effects were observed for IPOS total score and subscales, except for 'Communication' (Fmode = 5.9, p = 0.019). Fifty-eight percent preferred the electronic version. In the group 75+ years, 53% preferred the paper version. Only three entries in the free-text main problems differed between the versions. Conclusion: The very high equivalence in scores and free text between the IPOS and the eIPOS demonstrates that eIPOS is feasible and reliable in an older palliative population.

Since the end of the Cold War, the EU aims to advance to a relevant and autonomous actor in international politics—especially concerning security and defense politics. Scholars interested in whether the EU member states actually converge in their security and defense preferences often analyze strategy papers qualitatively, focusing on selected countries at specific points in time. In this article, we propose a dictionary approach for analyzing the development of security and defense preferences within the EU over the last three decades using quantitative text analysis. We make use of 163 strategy papers, published by all EU member states and the EU itself since 1994. The findings show that EU member states react similarly to international events, but do not converge substantially in their preferences. Furthermore, there is no substantial convergence to the position of the EU itself. We finally discuss usefulness and validity of quantitative text analysis in comparative research more broadly.

Objectives: Most researchers who study the effects of hormonal contraception on menstrual bleeding rely on self-reported data via paper diaries, for which completeness and timeliness have been shown to be poor. The purpose of this exploratory study was to compare the completeness and timeliness of bleeding data collected via paper diaries, text messages or smartphone application (a.k.a "app"). Methods: This was a sub-study of a double-blinded, placebo-controlled randomized trial comparing the effects of a non-steroidal anti-inflammatory drug, naproxen, with placebo when using a copper IUD. Participants tracked bleeding and symptoms over 112 days. Participants tracked bleeding daily using a paper diary as well as with either text messages or a smartphone app. Participants who used paper and the app were also able to record non-bleeding symptoms. Results: Twenty-five participants submitted diaries. Of these participants, 10 completed both paper and app diaries, 7 completed both paper and text messages, 4 completed the paper diary only, 4 completed the app only. Text messages had the most complete data (108 days), followed by the app (96 days) and paper diaries (84 days). The lag time between a bleeding event and the date recording that event was 0.10 days for text, 1.0 days for app, and 4.73 days for paper diaries. Participants using the app reported a median of 33 other symptoms over the study period compared to 7 for the paper diaries. Discussion: Our findings suggest texts demonstrated more complete and timely bleeding data than either paper diaries, or the app. Compared to paper diaries, the app delivered more complete, timely data, and also collected a large set of symptoms.

Objective: to analyse the artistic bindings of the eighteenth-century prints stored in the Historical-artistic Binding Database of the Royal Library, in order to locate the endpapers made with decorated papers, and to classify and describe them according to the proposals of the specialist literature. Methodology: The records from the database were retrieved using the "date" field, and the information is extracted from the "endpapers" and "notes" fields. The reproductions of the endpapers were analysed, identified and described following the classification model of decorated papers inspired by the works of Professor Carpallo Bautista, consisting of five techniques and their variants. Finally, a comparative analysis was carried out. Results: Among the 382 eighteenth-century prints with artistic bindings, ten were located and analysed that include endpapers decorated with xylographic plates, 135 with marbled or mottled papers (with designs corresponding to seven variants), four with paste-glued papers, three with dotted papers, 18 with gold and embossed papers, and four of other kinds such as silver or percaline paper.

The Dimensional Anhedonia Rating Scale (DARS) is a novel questionnaire to assess anhedonia of recent validation. In this work, we aim to study the equivalence between the traditional paper-and-pencil and the digital format of DARS. Sixty-nine patients filled the DARS in a paper-based and digital versions. We assessed differences between formats (Wilcoxon test), validity of the scales [Kappa and intraclass correlation coefficients (ICCs)], and reliability (Cronbach's alpha and Guttman's coefficient). We calculated the comparative fit index and the root mean squared error (RMSE) associated with the proposed one-factor structure. Total scores were higher for paper-based format. Significant differences between both formats were found for three items. The weighted Kappa coefficient was approximately 0.40 for most of the items. Internal consistency was greater than 0.94, and the ICC for the digital version was 0.95 and 0.94 for the paper-and-pencil version (F = 16.7, p < 0.001). Comparative Adjustment Index was 0.97 for the digital DARS and 0.97 for the paper-and-pencil DARS, and RMSE was 0.11 for the digital DARS and 0.10 for the paper-and-pencil DARS. We concluded that the digital DARS is consistent in many respects with the paper-and-pencil questionnaire, but equivalence with this format cannot be assumed without caution. [ABSTRACT FROM AUTHOR]

Is it really better to print everything, including software models, or is it better to view them on screen? With the ever increasing complexity of software systems, software modeling is integral to software development. Software models facilitate and automate many activities during development, such as code and test case generation. However, a core goal of software modeling is to communicate and collaborate. Software models are presented to team members on many mediums and two of the most common mediums are paper and computer screens. Reading from paper or screen is ostensibly considered to have the same effect on model comprehension. However, the literature on text reading has indicated that the reading experiences can be very different which in turn effects various metrics related to reader performance. This paper reports on an experiment that was conducted to investigate the effect of reading software models on paper in comparison with reading them on a computer screen with respect to cognitive effectiveness. Cognitive effectiveness here refers to the ease by which a model reader can read a model. The experiment used a total of 74 software engineering students as subjects. The experiment results provide strong evidence that displaying diagrams on a screen allows subjects to read them quicker. There is also evidence that indicates that on screen viewing induces fewer reading errors. [ABSTRACT FROM AUTHOR]

Objective: To assess differences between traditional paper bag ordering and online ordering from primary school canteens in terms of menu, usage and lunch order characteristics.Design: A cross-sectional study.Setting: New South Wales (NSW) primary schools that offered both paper bag and online canteen ordering.Participants: Students (aged 5-12 years) with a lunch order on the day of the observation.Results: Across the six school canteens, 59-90 % of all available items were listed on both the online and paper menus, with no significant differences in the nutritional quality ('Everyday'/'Occasional') or nutritional content (kJ/saturated fat/sugar/sodium) of menu items. In total, 387 student lunch orders were placed, containing 776 menu items. Most orders (68 %) were placed online. There were no significant differences between order modality in the quantity of items ordered or the cost of orders, or the nutritional quality of orders based on the classification system of the NSW Healthy School Canteen Strategy ('Everyday'/'Occasional'). However, nutritional analysis revealed that paper bag orders contained 222 fewer kJ than online orders (P = 0·001), 0·65 g less saturated fat (P = 0·04) and 4·7 g less sugar (P < 0·001).Conclusions: Online canteens are commonly used to order canteen lunches for primary school children. This is the first study to investigate differences between traditional paper bag ordering and online ordering in this setting. Given the rapid increase in the use of online ordering systems in schools and other food settings and their potential to deliver public health nutrition interventions, additional research is warranted to further investigate differences in ordering modalities.

Scientific papers are essential manifestations of evolving scientific knowledge, and arguments are an important avenue to communicate research results. This study aims to understand how the argumentation process is represented in scientific papers, which is important for knowledge representation, discovery, and retrieval. First, based on fundamental argument theory and scientific discourse ontologies, a coding schema, including 17 categories was constructed. Thereafter, annotation experiments were conducted with 40 scientific articles randomly selected from two different research areas (library and information science and biomedical sciences). Statistical analysis and the sequential pattern mining method were then employed; the ratio of different argumentation units and evidence types were calculated, the argumentation semantics of figures and tables analyzed, and the argumentation structures extracted. A correlation analysis between argumentation and rhetorical structures was also performed to further reveal how argumentation was represented within scientific discourses. The results indicated a difference in the proportion of the argumentation units in the two types of scientific papers, as well as a similar linear construction with differences in the specific argument structures of each knowledge domain and a clear correlation between argumentation and rhetorical structure.

Objectives. To evaluate the usefulness of a novel acoustic uroflowmetry- (UFM-) based mobile application (app) voiding diary (VD) focusing on the (1) compliance and (2) correlation with a conventional paper-based VD. Materials and Methods. A total of 78 patients were included between December 2019 and June 2020, and a subsequent review of all data was performed. The analyzed data were as follows: (1) survey of convenience/satisfaction/preference comparing the two methods, (2) compliance regarding the completeness of both methods, and (3) correlation of each metric (24-hour urine volume, nocturnal urine volume, nocturnal polyuria index, total number of voids, number of daytime voids, number of nocturnal voids, and maximal bladder capacity) between the two methods. Results. The survey results of convenience, satisfaction, and preference were as follows. With regard to convenience and satisfaction area, higher scores are reported in the mobile app VD (mean ± standard deviation (SD); convenience: 7.47 ± 2.19 [app] vs. 4.20 ± 2.49 [paper]; satisfaction: 7.36 ± 2.17 [app] vs. 5.07 ± 2.65 [paper]). The median score of the overall preference for using the mobile app instead of the paper-based VD was 9 out of 10 (mean ± SD 7.82 ± 2.68). We also found a good correlation between the two methods for nocturnal urine volume (r = 0.55 , p = 0.04), nocturnal polyuria index (r = 0.66 , p = 0.23), total number of voids (r = 0.9 , p = 0.02), number of nocturnal voids (r = 0.83 , p = 0.02), and maximal bladder capacity (r = 0.89 , p = 0.04). Conclusion. The acoustic UFM-based mobile app VD demonstrated favorable findings compared to the conventional paper-based VD. [ABSTRACT FROM AUTHOR]

The gold standard for measuring anhedonia is the Snaith-Hamilton Pleasure Scale (SHAPS). To date, there are no validated electronic versions of this questionnaire. We aim to study the equivalence between the traditional paper-and-pencil format and a digital version of the SHAPS. A group of 67 patients completed both SHAPS formats, and differences between formats were assessed. McNemar's test showed no significant differences between the two systems. The Kappa coefficient was over 40% for most items, and reliability was above 0.8, showing good to excellent levels of internal consistency. Thus, we have demonstrated a close equivalence between paper-and-pencil and electronic SHAPS. [ABSTRACT FROM AUTHOR]

Environmental and economic concerns are driving tissue paper manufacturers to improve understanding of the relationships between fibres, the networks they form, the forming process, and the final tissue paper properties. This work investigated how pulp fractionation, refining, or addition of microfibrillated cellulose (MFC) affect the compromise between absorbency and strength of 33 ± 2 g/m² model papers made of bleached eucalyptus kraft pulp. The results showed that the compromise of properties was better when fibres were refined than when MFC was added. The absorbency capacity of 2%wt MFC-paper was almost 20% lower than the capacity of the refined paper at the same dry strength. The calculated additional storage capacity due to water-induced deformations of the fibre network was 40% lower in the same range of bulk. By forming a high viscosity gel at inter-fibre contacts, MFC could limit the occurrence of major fibre and network deformation mechanisms when water was imbibing the paper. [ABSTRACT FROM AUTHOR]

Bamboo has being used as alternative raw material for construction, reinforcing fibers, paper production, among other applications. Although its recognized potentials as raw material, there are doubts about its environmental performance compared to traditional wood-based products, including paper production, which hinders bamboo-based paper plants in large scales. This study aims to assess the environmental performance of producing office paper from bamboo. Emergy synthesis (with 'm') and global warming potential indicators are calculated and compared with the traditional eucalyptus paper-based production. Results highlights the importance in including the renewability fractions of each input resources into emergy calculations for production systems with high human-labor intensity such as the bamboo agricultural production. Office paper produced from bamboo has similar renewability (28%), moderate environmental load (3.23 vs. 2.49), and emergy unsustainability (0.34 vs. 0.60) compared to paper produced from eucalyptus, but bamboo showed lower performance for global efficiency (568 vs. 442 sej/ton paper), emergy yield (1.09 vs. 1.49), and emergy investment (10.79 vs. 2.05). Focusing on global warming potential, office paper produced from bamboo releases 98 kgCO 2 eq. /ton paper compared to 56–267 kgCO 2 eq. /ton paper for eucalyptus. Notwithstanding, bamboo-based office paper demands four times more land area of agricultural production than eucalyptus, but it has a positive social aspect by requiring higher amount of direct human labor. This work shows the advantages of using eucalyptus rather than bamboo in producing office paper from an emergy and land demand perspectives, while global warming can still be considered inconclusive. Future efforts should consider a quantitative and qualitative analysis of human labor availability in both systems, as well an economic analysis to support discussions towards more sustainable office paper production from different raw materials. • Environmental load of bamboo and eucalyptus for office paper production are compared. • Bamboo has lower emergy performance than eucalyptus. • Including the renewability fraction of labor and services better reflects emergy results. • Bamboo paper emits 98kgCO2eq/ton, eucalyptus paper emits 56–267kgCO2eq/ton. • Bamboo paper needs 4x land compared to eucalyptus and requires more human labor.

A new coating method was developed, based on cellulose regenerated from an N-methylmorpholine N-oxide (NMMO) solution applied to paper. In particular, the purpose of this study was to compare the effectiveness of the "deep coating" method using cellulose regenerated from NMMO solution and the classic pulp refining process as methods to improve paper mechanical properties and overall quality. The "deep coating" name comes from the fact that the coating process is combined with subsequent heating of the coating before its final solidification. As a result of this operation, deep penetration of the cellulosic solution into the paper structure occurs. This increases the contact surface of the solution with the cellulosic fibers, which increases the strength properties of the paper structure. It was found that the cellulosic coating increased the apparent density of the paper, the tensile strength, the elongation, the resistance to bursting, and the double fold number. However, the coating also decreased the air permeability and the tear resistance of the paper samples. Despite some technological difficulties, this method could be an attractive solution in the case of a need for additional functionalization of a paper structure. [ABSTRACT FROM AUTHOR]

Alkyl ketene dimer (AKD) and rosin sizing are used in papermaking to decrease paper's tendency to absorb liquid water. Earlier information regarding the effects of internal sizing on paper dry strength is not consistent. In the present laboratory study, AKD sizing of handsheets made from Nordic bleached softwood pulp (NBSK), and rosin sizing of handsheets made from Nordic hardwood chemi-thermomechanical pulp (CTMP) were done via an internal sizing method, and by immersing handsheets in aqueous sizing agent dispersion. In the study, AKD sizing had no significant effect on the dry strength of NBSK handsheets. The result corresponds to practical experiences of papermakers. However, both AKD sizing methods resulted in a substantial and long-lasting increase of handsheet wet-strength. Unlike internal AKD sizing of NBSK handsheets, rosin internal sizing of CTMP handsheets resulted in decreased handsheet dry strength. The decrease indicates that, under the conditions present during the experiment, rosin sizing agents interfered with interfiber hydrogen bonding of CTMP fibers. Given that, in practice, no such undesired effects have been commonly linked to rosin sizing, the observed effect may be specific to sheet-making conditions. However, the effect of rosin sizing on strength properties and their variation cannot be ruled out completely. [ABSTRACT FROM AUTHOR]

• The use of the ProFibro app for six weeks was not more effective than the use of a traditional paper book with similar content for health-related quality of life, symptoms, or self-care agency in individuals with fibromyalgia. • Improvements on severity of symptoms in both groups suggest that the self-care program using a mobile app or a paper book may be beneficial in individuals with fibromyalgia. • The Sleep Strategies was the most used function of the ProFibro app, followed by the Exercise Program, and the diary for the practice of gratitude. The ProFibro application (app) was developed as a Mobile Health resource to promote self-care in fibromyalgia management. This study aimed to assess the effects of the use of the ProFibro app for six weeks compared to the use of a traditional paper book of similar content to improve health-related quality of life, symptoms, and self-care agency in individuals with fibromyalgia. Forty individuals with fibromyalgia were included in this randomized, single-blind, parallel trial. One group received intervention content using the ProFibro app on a smartphone while the other received similar information using a paper book. Participants were assessed at baseline and after six weeks. The primary outcome was the Revised Fibromyalgia Impact Questionnaire. Secondary outcomes were Widespread Pain Index, Pain Visual Analog Scale, Symptom Severity Scale, and Appraisal of Self-Care Agency Scale – Revised. No differences in changes were found between groups at the end of the treatment for any outcome. Both groups showed improvements in symptom severity. The use of the ProFibro app for six weeks was not more effective than the use of a traditional paper book with similar content for health-related quality of life, symptoms, or self-care agency in individuals with fibromyalgia. Both groups showed improvements from baseline on severity of symptoms, suggesting that the self-care program using a mobile app or a paper book may be beneficial for individuals with fibromyalgia.

Users' experiences in mental health assessment are multifaceted, including their emotional experiences. Yet, studies of mobile apps for psychiatric assessment have centered on diagnostic accuracy and perceived usability, with little consideration of the impact of user emotional experiences. In this study, we focused on users' perceived usability and emotions and compared the user experience of a paper-and-pencil and an app-based collection of mental health screening questionnaires: EarlyDetect. The System Usability Scale (SUS) and modality-directed emotion questionnaires were administered using paper-and-pencil or iPad. Modality was assigned pseudo-randomly on patients' first visit at a referral-based mental health clinic. We found that patients assigned to the iPad app reported a significantly higher SUS score than patients assigned to paper-and-pencil, qualified by a modality-by-gender interaction where modality effects were significant for men but not for women. Moreover, enjoyment was positively linked to perceived usability, whereas boredom, frustration, and anxiety were negatively linked to usability. Our findings illustrate the added value of studying user experience applied to psychiatric assessments, where both emotions and gender-specific user experience should be taken into consideration. We further discuss the implications for psychiatric assessments via app versus traditional data collection. [ABSTRACT FROM AUTHOR]

The aim of this study was to examine the effects that reading on screens (using digital devices with different screen sizes) and on paper have on reading time and comprehension. The study group was comprised of126 secondary students from a private school. To ensure balance, the participants were assigned into test groups, formed according to the size of the reading device, based on class levels, gender, and average school grade. In the data collection process, a narrative text was transferred to both print and electronic media. Access to the text was provided on paper and three digital devices. There were no time limitations. After reading, participants were given comprehension tests that consisted of twenty multiple-choice questions. Female participants' on-screen comprehension scores were found to be relatively higher compared to their paper comprehension scores. They also acquired better scores as the screen size increased. Conversely, male participants had higher comprehension scores on tablets and smart phones. Participants who read the text on smart phones and tablets completed the tasks in less time compared to other groups. However, the effects of reading modality on comprehension and reading time were not found to be statistically significant in either the male or female groups. [ABSTRACT FROM AUTHOR]

Graphs drawn on rastered paper and a monumental steel sculpture display how visual artists Paul Klee and Henrik Neugeboren conceived of Johann Sebastian Bach's polyphonic style in 1920s Germany. Focusing on the representational decisions behind these artistic translations of music, this article explores the ways in which such artifacts manifest a specific analytical lens. It highlights congruencies with and deviations from the theoretical framework of "linear counterpoint," as epitomized in Ernst Kurth's influential treatise from 1917, and thereby positions the artworks within the controversial reception history of Bach's music and atendant theoretical frameworks in the early twentieth century. More generally, the article proposes that graphical and sculptural renderings of music can offer the opportunity to investigate music theory's intangible methods and conceptual metaphors through different sensory experiences.

Sewage fine sieved fraction (FSF) is a heterogeneous substrate consisting of mainly toilet paper fibers sequestered from municipal raw sewage by a fine screen. In earlier studies, a maximum biodegradation of 62% and 57% of the sewage FSF was found under thermophilic (55 °C) and mesophilic (35 °C) conditions, respectively. In order to research this limited biodegradability of sewage FSF, this study investigates the biodegradation of different types of cellulosic fibers-based hygiene papers including virgin fibers based toilet paper (VTP), recycled fiber based toilet paper (RTP), virgin pulp for paper production (VPPP) as a raw material, as well as microcrystalline cellulose (MCC) as a kind of fiberless reference material. The anaerobic biodegradation or digestibility tests were conducted under thermophilic and mesophilic conditions. Results of the experiments showed different biomethane potential (BMP) values for each tested cellulose fiber-based substrate, which might be associated with the physical characteristics of the fibers, type of pulping, presence of lignin encrusted fibers, and/or the presence of additive chemicals and refractory compounds. Higher hydrolysis rates (K h ), higher specific methane production rates (SMPR) and shorter required incubation times to achieve 90% of the BMP (t 90% CH 4 ), were achieved under thermophilic conditions for all examined substrates compared to the mesophilic ones. Furthermore, the biodegradability of all employed cellulose fiber-based substrates was in the same range, 38–45%, under both conditions and less than the observed FSF biodegradability, i.e. 57–62%. MCC achieved the highest BMP and biodegradability, 86–91%, among all cellulosic substrates. [ABSTRACT FROM AUTHOR]

A combination of experimental techniques was employed to test primary fragmentation and char particle attrition by abrasion during fluidized bed (FB) combustion of raw paper sludge (Raw-PS), hydrothermally treated paper sludge (HTT-PS), and a subbituminous coal (Sub-C), for comparison. The hydrothermal treatment (HTT) was conducted by a pilot-scale reactor at 197 °C (1.9 MPa) for 30 min. The results showed that all three samples extensively underwent primary fragmentation. Char attrition tests under inert conditions showed that Sub-C intensely experienced particle rounding off at the beginning, but after that it became very strong against mechanical abrasive attrition, followed by HTT-PS and Raw-PS, respectively. The oxidative char attrition tests showed that Sub-C exhibited an initial low amount of carbon elutriation rate followed by an attrition enhancement effect at later stages of burn-off, whereas for the Raw-PS and HTT-PS attrition was always lower than under inert conditions due to extensive postcombustion of fines. HTT-PS always produced a lower amount of elutriated carbon than Raw-PS and this indicates better combustion performance as well as lower unburned carbon emission. Finally, the Primary Ash Particle Size Distribution (PAPSD) of the three fuels was determined, showing that the paper sludge would contribute much more than coal to the ash bed inventory in a full-scale FB combustor.

Over the last few decades, researchers have been investigating the uses of student-generated questions (SGQs) in multifarious areas. In understanding the potential benefits of SGQ, this action research is designed to examine a group of students' perceptions after experiencing interventions of web-based student generated questions (e-SGQs) and paper-based student-generated questions (PB-SGQs) in the classroom. For this research, ten students were recruited to construct test items for their own mid-term preparation. The student generated items were split fairly evenly with about half of the items being e-SGQs and the other half being PB-SGQs. The two modes were compared through the analyses of a survey, a group interview, and individual in-depth interviews. The data analyses reveal that the participants perceived their experiences of generating questions to be very helpful for understanding their class content. Although many of them clearly recognized the advantages of e-SGQs as an educational tool, most of the participants chose PB-SGQ over e-SGQ. This result can be explained by the survey and interview data which illustrate that the respondents preferred the test taking strategies that they were used to such as marking, underlining, and skimming through the test items on a paper.

Background: Paper patching, a method that places cigarette paper over the most mobile quadrants of the tympanic membrane, is one of the treatment options for patulous eustachian tube (PET). Aims/Objectives: The objective of this study was to compare the outcomes of two different treatment strategies for PET. Material and methods: Twenty-three patients underwent paper patching of the tympanic membrane and 16 patients were treated with nasal saline irrigation with or without ipratropium bromide nasal spray. Medical records were reviewed for resolution of PET symptoms as categorical variables (complete remission, partial remission, or no improvement) with a minimum follow-up of 3 months. Results: Immediately after undergoing paper patching, 20 of the 23 patients (87.0%) reported complete remission (CR). The percentage of CR after paper patching was 82.6% at 1 month and 65.2% at 3 months. A greater percentage of patients reported CR of aural symptoms in the paper patching group than in the nasal irrigation group at both 1 and 3 months after treatment (p < .05). Conclusions and significance: Repetitive paper patching resolves aural discomfort in most PET patients for at least 3 months and can be considered as a first-line treatment option for PET in the outpatient setting.

Objective: The primary aim of this study was to investigate the immediate and delayed effects of kinesiotape (KT) on postural control and patient-reported outcome measures under challenging conditions in individuals with anterior cruciate ligament reconstructions. Methods: Thirty-two anterior cruciate ligament-reconstructed patients for whom 6 months had passed since their operation were randomly assigned to either the KT (n = 16, aged 21.8 [5.5] y) or the placebo KT (n = 16, aged 24.0 [5.1] y) groups. Initially, both groups stood barefoot on a force platform while performing postural tasks in 4 randomized conditions (eyes open, eyes closed, cognitive task, and foam). Before the experiment, patients would bring the 4 conditions, which were written on folded papers, one by one, and in this way, the order of conditions for the examiners was determined. The patients' evaluations were conducted immediately and 48 hours after KT application. Postural control measures, with area and displacement of the center of pressure (CoP) in anterior--posterior and medial--lateral directions, and mean total velocity displacement of CoP (MVELO CoP) served as dependent variables. In addition, the International Knee Documentation Committee score was measured pretreatment and 48 hours posttreatment. Results: Significant group-by-time interactions were observed for displacement of COP in medial--lateral direction (P = .002) and MVELO CoP (P = .034). MVELO CoP significantly decreased (mean difference = 0.60, P = .009) immediately after KT application compared with preapplication measures. In the placebo group, a statistically significant decrease in MVELO CoP (mean difference = 0.869, P = .001) was observed at 48 hours post-KT compared with preapplication values. International Knee Documentation Committee scores significantly improved at 48 hours post-KT application in both groups (P < .05). Conclusions: Though observed at different time points, both KT (immediately after the intervention) and placebo KT (48 h after the intervention) were found to improve postural control measures. It appears that the changes in postural control may be more related to proprioceptive enhancement due to KT rather than the specific KT pattern. [ABSTRACT FROM AUTHOR]

The genetics and evolution of complex traits, including quantitative traits and disease, have been hotly debated ever since Darwin. A century ago, a paper from R.A. Fisher reconciled Mendelian and biometrical genetics in a landmark contribution that is now accepted as the main foundation stone of the field of quantitative genetics. Here, we give our perspective on Fisher's 1918 paper in the context of how and why it is relevant in today's genome era. We mostly focus on human trait variation, in part because Fisher did so too, but the conclusions are general and extend to other natural populations, and to populations undergoing artificial selection.

Summary: This paper proposes a single‐phase dual‐input step‐up switched‐capacitor multilevel inverter that employs three capacitors, 15 switches, and two diodes to provide 13 voltage levels and triple‐voltage boosting factor in its symmetric form and 37 levels with voltage boosting factor of 3.6 in its asymmetric version. This high boosting factor is accomplished without utilizing any transformer. For each output voltage level, there exists flow paths for both the positive and negative load current directions, which makes the proposed inverter capable of supplying any load type with variety of power factors (zero to unity). The voltage balancing of the capacitors takes place naturally, which tackles the need to auxiliary charge‐balancing circuits or control mechanisms. The proposed inverter can generate negative levels without the end‐side H‐bridge. Moreover, the voltage stress on the semiconductor devices is less than the peak output voltage. The increased number of levels and sinusoidal‐like waveform of the output voltage waveform enhances the quality and lowers the harmonic content of the load voltage and current waveforms, even for resistive loads. As the result, the load‐side filter can be downsized or removed. This paper employs the fundamental frequency method (FFM) as the switching technique, which is simple to implement and also operates the switches at low frequencies, leading to lower switching losses. The ascendancy of proposed inverter over similar counterparts has been investigated through comprehensive comparative analysis. Moreover, the correct performance of the proposed inverter at different modulation indices, and load types as well as during dynamic load changes has been verified by simulation and experimental analysis.

Purpose: In traditional methods, a one-directional distance transformation is employed to eliminate the near-singularity in the radial direction. However, when the projection point of the source point is near the boundary of the integral element, the near-singularity in the circumferential direction still exists, resulting in large errors in the numerical results. The purpose of this paper is to propose a bi-directional distance transformation for the elimination of near-singularities in two directions arising from the irregular integral element. Design/methodology/approach: The sources of the circumferential near-singularity caused by irregular sub-triangular element are analyzed in this paper. A bi-directional distance transformation based on the (a, β) transformation is proposed to eliminate the near-singularities in the two directions. The (a, β) transformation is initially introduced to separate the integral variables and streamline the implementation of subsequent transformations. In the transformed (a, β) coordinate system, a new distance transformation applied in the circumferential direction is constructed. Findings: With the proposed method, the radial and circumferential near-singularities are eliminated using two different distance transformations, respectively. Thus, accurate calculations of the nearly singular integrals can be achieved, irrespective of the shape of the integral element. Originality/value: Numerical examples are presented to calculate the nearly singular integrals of different orders over both the linear integral element and the quadratic integral element. Comparative studies demonstrate that the proposed method significantly improves the accuracy of these calculations. [ABSTRACT FROM AUTHOR]

The rapid development of social reform and the economy has brought great challenges to the mental health of college students. However, there are few studies on the impact of these psychological problems on college students' English learning. As a special group about to enter society, studying the mental health of college students in foreign language learning is of great significance. This paper discusses the principle of Artificial Intelligence (AI) technology and the interactive mechanism to support college students' foreign language learning. Additionally, the adaptability supporting college students' foreign language learning is analyzed according to the current situation of AI supporting foreign language learning. Then, the mental health of college students in the AI environment is investigated and analyzed. This paper takes foreign and non-foreign language majors of Changchun University of Technology as the object and uses questionnaires, interviews, and classroom observation to obtain basic data. The results show that college students' adaptability to foreign language learning is higher than that of non-foreign. Students' intelligent operation and knowledge storage level impact their adaptability to foreign language learning. Psychological health problems include learning anxiety, loneliness, depression, and inferiority in college students' foreign language learning. These negative emotions, to a certain extent, affect the learning effect of college students' foreign language learning. This paper is of great significance to the adaptability of college students' foreign language learning to the intelligent environment and the analysis of their mental health problems. This paper hopes to provide data reference for the research on improving college students' foreign language learning effects. [ABSTRACT FROM AUTHOR]

Background: Multi-nozzle nebulisers for pressurised intraperitoneal aerosol chemotherapy (PIPAC) are implemented in clinical practice to improve the homogeneity of tissue drug delivery. Nonetheless, the advantages of such devices over one-nozzle nebulisers have not been demonstrated thus far. In this study, we compared the performance of multi- and one-nozzle nebulisers by conducting physical and ex vivo pharmacological experiments. Methods: The one-nozzle nebuliser Capnopen® and the multi-nozzle nebuliser were the subjects of this study. In physical experiments, the aerosol droplet size was measured by laser diffraction spectroscopy. Spatial spray patterns were depicted on blotting paper. Pharmacological experiments were performed on the enhanced inverted bovine urinary bladder model, demonstrating real-time tissue drug delivery, aerosol sedimentation and homogeneity of doxorubicin and cisplatin tissue distribution. Results: The multi-nozzle nebuliser had a sixfold greater aerosolisation flow and a threefold greater angle of aerosolisation than Capnopen®. The aerosol particle size and distribution range were higher than that of Capnopen®. Spray patterns on blotting paper were more extensive with the multi-nozzle nebuliser. Real-time tissue drug delivery with the multi-nozzle nebuliser was over 100 ml within 1 min, and the aerosol sedimentation was 48.9% ± 21.2%, which was not significantly different from that of Capnopen®. The doxorubicin and cisplatin tissue concentrations were greater with Capnopen®. Although there was no significant difference in the homogeneity of doxorubicin distribution between the two devices, the homogeneity of cisplatin distribution was significantly higher with Capnopen®. Conclusion: The multi-nozzle PIPAC nebuliser did not fulfil expectations. Even though the surface spray patterns were broader with the multi-nozzle nebuliser, the tissue drug homogeneity and concentration were greater with Capnopen®. [ABSTRACT FROM AUTHOR]

Seventy seven research papers published from 1986 to 2018 were observed. These papers investigated PTEs (Pb, Cd, Cu, As, Fe, Zn, Ni, and total Cr) in leafy (mint, spinach, coriander, and lettuce) and tuberous (potato, carrot, radish, and onion) vegetables irrigated by wastewater. The studies observed in our paper were conducted in 19 countries. The PTEs concentrations were compared among studies and the human health risk was observed. According to the obtained meta-analysis results, PTEs concentrations (mg/kg) in vegetables were found in the following order Zn (34.216)> Cu (22.581)> Ni (14.056)> Pb (10.173)> Cr (8.308)> Fe(8.130)> As(1.881)> Cd (1.763). Hazard index for children was higher than that for adults and for both groups, the calculated HQ was higher than 1, which indicates that there is a health risk for the consumers. This study provides a comprehensive analysis that demonstrates the urgent necessity for treating PTE pollution in agricultural areas worldwide. [ABSTRACT FROM AUTHOR]

In the field of medical imaging, there is a strong requirement for the storage of an immense volume of digitized medical image data. The digital image must be compressed heavily before storing and transferring it because of having restricted bandwidth and scope of storage. When compression of images is done at a lower bit rate it reduces the image fidelity that results in a drop in quality but poses many challenges to overcome and prevents diagnostic miscalculations with great compression rates for reduced storage and quick transmission. To overcome this challenging issue several hybrid efficient compression procedures solely for medical digital images have been introduced in recent years. The transformation of image, quantization, and encoding is part of image compression. This paper presents a qualitative and comprehensive review of image compression techniques for two-dimensional (2D) still and three-dimensional (3D) medical images. The features and constraints associated with various compression methods for compressing grayscale images are reviewed and discussed in this paper. In-depth reviews of the practical concerns and difficulties in the medical scan compression arena are provided. [ABSTRACT FROM AUTHOR]

Adopting a hermeneutic approach and horizontal and vertical interpretation methods, this study primarily explores the metaphysical concept of loveinduced mystic intoxication in the Iranian polymath Mullā Muḥsin Fayḍ Kāshānī's mystic poetry. Secondarily, it discusses the implications of mystic intoxication in the meaning of life. Furthermore, the paper briefly positions Fayḍ Kāshānī's account in the contemporary categories of the meaning of life: supernaturalism, naturalism, and nihilism. Additionally, elucidating the perspectives of the contemporary philosopher John Cottingham, the paper examines Kāshānī's view through Cottingham's philosophy. Central to Kāshānī's poetry, ignited by divine love, the spiritual seeker transcendends their self, getting absorbed into the Divine to the point where they become unaware of their self. This epistemic unawareness is mastī (intoxication) or bīkhudī (selflessness)--which, for Kāshānī, has profound implications on life's meaning. Unlike the "extreme God-centric" view--which situates the purpose of life solely in fulfilling God's purpose--Kāshānī's "moderate Godsoul-centric supernaturalist" view recognizes that while divine love, intoxication, and knowledge infuse more profound depth to the meaning of life, other aspects also add to the meaning in life--like the simpler forms of piety and everyday existence. A framework in which morality is instrumental. Similarly, for Cottingham, life has value and meaning beyond solely fulfilling God's purpose. Nevertheless, while basic pleasures and desires might independently exist and have meaning, higher elements like moral virtue, crucial to life's meaning, are contingent on God's purpose.

Autism Spectrum Disorder (ASD) and Developmental Language Disorder (DLD) have traditionally been considered separate disorders, although some similarities and overlaps in certain aspects of language have been detected. In this paper, we compare the deficits in receptive grammar in these two disorders. We analyse the proportion of grammatical errors in relation to semantic complexity in 84 children divided into four groups: children with autism language impairment (ALI), with autism language normal (ALN), with DLD, and with typical development (TD), all groups with the same age of receptive vocabulary. The results show significant differences in the comprehension of grammatical structures, both simple (canonical and non-reversible) and complex (non-canonical and reversible). Children with ASD and DLD show different language profiles depending on the syntactic complexity. In the simplest structures, no differences are found between the groups, starting at an equivalent vocabulary age of 7:8 years. However, there are differences between the ALI and DLD groups with respect to the TD group in the more complex structures, starting at an equivalent vocabulary age of 3 years. Therefore, both groups ALI and DLD present the greatest difficulties compared to ALN and TD. The paper discusses the importance of attending to these differences, since the repercussion of comprehension difficulties increases as children grow. [ABSTRACT FROM AUTHOR]

Recent technological advancements are transforming the architecture, engineering and construction (AEC) industry, focusing on digitalization and automation opportunities as drivers for improvement. In a realm as complex as building permitting, the drive for automation should be anchored in a comprehensive understanding of the process it seeks to transform. Furthermore, analyzing the process from a global perspective is essential for identifying opportunities for improvement. This article addresses the need for a systematic and robust approach to evaluate and compare building permit processes globally. Traditional approaches for process comparisons fail to capture the intricacies of a building permit process. Hence, in this paper, the authors propose and introduce the Process Analysis and Comparative Evaluation methodology, PACE-BP, which was tailored for building permit processes. The proposed method relies on a previously developed framework for process mapping which provides a comparable data set of building permit process maps in different countries. The comparative evaluation is then performed by assessing the maps based on predefined indicators, which are used to compile a representative vector for each process. The computational method for compiling the vectors and calculating the similarity measures between pairs of processes is described in detail. The application of PACE-BP for analyzing and comparing building permit processes in Germany, the US, Israel, and Italy is demonstrated in this paper. Our findings challenge the pursuit of a universal "best practice," emphasizing the need to balance priorities and stakeholder's objectives. The PACE-BP method is a powerful tool for policymakers and stakeholders, providing meaningful insight into existing processes and pinpointing drawbacks and limitations in current practices, while revealing opportunities for improvement.

This paper introduces a novel platform that integrates three preconditioning matrices based on conservative variables: the Turkel, Choi–Merkle and Onur matrices. The platform aims to compare these matrices in terms of accuracy and robustness by investigating their performance in solving three distinct and challenging high-gradient laminar flow problems: (i) Bi-Plane NACA0012 airfoil, (ii) lid-driven flow in a square cavity and (iii) flow in a planar T-junction. These problems serve as new and challenging test cases to accurately determine the abilities of the preconditioning matrices. The preconditioning matrices are applied to evaluate the numerical solutions, and their performance in complex flow fields is assessed in terms of accuracy and efficiency. By solving these flow problems, the effectiveness of the preconditioning matrices is thoroughly analyzed. By integrating these preconditioning matrices into a single platform, this paper significantly contributes to the field. The approach enables a direct and meaningful comparison of the performance of the Turkel, Choi–Merkle and Onur matrices in solving these new and challenging laminar flow problems. While all three matrices demonstrate comparable accuracy in predicting flow characteristics like pressure coefficients, Turkel's method shows superior convergence acceleration across the almost test cases due to alpha parameter and modifications of the momentum equations. In the external flow case, Turkel converges 22–53% faster than the other matrices by adjusting momentum terms with an alpha parameter. For the internal lid-driven cavity case, Turkel again accelerates convergence up to 38% over Choi–Merkle as Reynolds and Mach numbers increase. However, Onur's method stalls at high Reynolds/Mach numbers. At low values of Reynolds and Mach numbers, Onur reduces computational cost by 17%. Finally, for the T-junction case, Turkel and Choi–Merkle perform almost identically, decreasing CPU time by 55% vs Onur, which lacks convergence robustness. While the preconditioning matrices have similar accuracy, Turkel offers the best convergence improvement by accounting for momentum effects. Onur works well at low Reynolds/Mach numbers but shows limitations at higher values. The selection of the optimal preconditioning matrix should be based on whether momentum or viscosity dominates in the flow field, as well as the intensity of the viscosity gradient rate.

Background Non-cellulose dried matrix spotting (DMS) cards are an alternative to filter paper (FP) for bloodspots. We compared the interpatient distributions of bloodspot areas between DMS and FP for a fixed volume of application of whole blood, and examined correlations of areas with hematocrit. Methods EDTA-whole blood adult patient samples ( n = 49; 25 males, 24 females) were utilized after routine measurement of hemoglobin and hematocrit. Replicate (4 ×) bloodspots were produced by bolus drop application of 50 μL whole blood via a fixed-volume pipettor to either FP or DMS. Dried bloodspot areas were determined by image analysis. Results Hematocrits (HCT) were normally distributed (HCT = 30.9 ± 5.3%). For both FP and DMS, bloodspot areas ( a , cm 2 ) across patients were normally distributed: for FP, a = 1.11 ± 0.056 cm 2 (± 5.0%); for DMS, a = 0.378 ± 0.037 cm 2 (± 9.9%). Relative bloodspot area differences across the population range were > 20% for both DMS and FP. Correlation of bloodspot areas to hematocrit was negative for FP ( r = − 0.80) but positive for DMS ( r = + 0.78). Conclusions Interpatient variation in blood volume per area is a preanalytical variable for both DMS and FP bloodspots. Hematocrit is but one interpatient variable, as correlations of fixed-volume bloodspot areas with hematocrit across patients were substantially inexact ( r 2 < 0.65). [ABSTRACT FROM AUTHOR]

Aims and objectives: To assess and compare the quality of paper-based and electronic- based health records. The comparison examined three criteria: content, documentation process and structure. Background: Nursing documentation is a significant indicator of the quality of patient care delivery. It can be either paper-based or organised within the system known as the electronic health records. Nursing documentation must be completed at the highest standards, to ensure the safety and quality of healthcare services. However, the evidence is not clear on which one of the two forms of documentation (paper-based versus electronic health records is more qualified. Methods: A retrospective, descriptive, comparative design was used to address the study’s purposes. A convenient number of patients’ records, from two public hospitals, were audited using the Cat-ch-Ing audit instrument. The sample size consisted of 434 records for both paper-based health records and electronic health records from medical and surgical wards. Results: Electronic health records were better than paper-based health records in terms of process and structure. In terms of quantity and quality content, paper-based records were better than electronic health records. The study affirmed the poor quality of nursing documentation and lack of nurses’ knowledge and skills in the nursing process and its application in both paper-based and electronic-based systems. Conclusion: Both forms of documentation revealed drawbacks in terms of content, process and structure. This study provided important information, which can guide policymakers and administrators in identifying effective strategies aimed at enhancing the quality of nursing documentation. Relevance to clinical practice: Policies and actions to ensure quality nursing documentation at the national level should focus on improving nursing knowledge, competencies, practice in nursing process, enhancing the work environment and nursing workload, as well as strengthening the capacity building of nursing practice to improve the quality of nursing care and patients’ outcomes.

Abstract: In the present work, the analytical potential of laser induced breakdown spectroscopy (LIBS) for the discrimination of paper types and prints made by digital printers on these papers was assessed. Six different paper types (including standard office papers, color paper and non-bleached paper), and eight printers (including laser and inkjet, as well as color and black printers) were included in the study. Only one or two laser shots were delivered to each sample in order to cause minimal sample destruction and provide maximum spatial resolution. The statistical evaluation of LIBS spectra was performed by multiple methods including three comparative functions (linear correlation, sum of squared deviations and overlapping integral) as well as two advanced statistical methods (multivariate curve resolution alternating least squares (MCR-ALS) combined with classification tree and discriminant analysis (DA)). The best classification results were obtained with the newly introduced MCR-ALS/DA approach, which proved to be 96.3% accurate in the identification of the paper type and 83.3% accurate in the identification of the printer type, based on the LIBS spectrum collected from just a single laser shot to the sample. It was found that the UV part of the LIBS spectrum can be used most efficiently for the discrimination. [Copyright &y& Elsevier]

Microbial communities play a vital role in maintaining soil health. A multiphasic approach to assess the effect of pulp and paper mill effluent on both the structure and function of microbial soil communities is taken. Bacterial communities from agricultural soils irrigated with pulp and paper mill effluent were compared to communities form soils irrigated with well water. Samples were taken from fields in the state of Uttarakhand, India, where pulp and paper mill effluent has been used for irrigation for over 25 years. Comparisons of bacterial community structure were conducted using sequencing of the 16S rRNA gene from both isolates and clone libraries attained from the soil. Community-level physiological profiling was used to characterize the functional diversity and catabolic profile of the bacterial communities. The multiphasic approach using both physiological and molecular techniques proved to be a powerful tool in evaluating the soil bacterial community population and population differences therein. A significant and consistent difference in the population structure and function was found for the bacterial communities from soil irrigated with effluent in comparison to fields irrigated with well water. The diversity index parameters indicated that the microbial community in pulp and paper mill effluent irrigated fields were more diverse in both structure and function. This suggests that the pulp and paper mill effluent is not having a negative effect on the soil microbial community, but in fact may have a positive influence. In terms of soil health, this finding supports the continued use of pulp and paper mill effluent for irrigation. This is however only one aspect of soil health which was evaluated. Further studies on soil resistance and robustness could be undertaken to holistically evaluate soil health in this situation. [ABSTRACT FROM AUTHOR]
