The article seeks to identify if cryptocurrency white papers bring purely technical positions. The research is justified on the growing discussion regarding the regulation of cryptocurrencies. Aside this discussion, there is a scenario in which cryptocurrencies seem to have emerged precisely from an attempt to move away from authoritative public control. At first, we analyzed the conceptualization of white papers, and their purposes. Subsequently, we evaluated the content of the cryptocurrency white papers with the highest market cap at the time of the esearch. We identified the presence of political-ideological content coupled with the technical content in these documents. Finally, the presented result shows that political-ideological elements in white papers can serve the regulating agent in their decision-making process, either to decide whether or not to regulate, but also to define the limits of their performance.

This paper includes an analysis of academic papers that focus on cultural aspects written by MA students in the ‘Teach & Learn in Spain’ program at Instituto Franklin-UAH. The percentage of academic papers focusing on cultural aspects written by these students who acted as Language Assistants (LAs) in bilingual schools in Spain is quite high. This suggests the importance of the cultural component in the teaching of English as a second language and their high level of sociocultural awareness. Thus, this paper has several objectives: a) to determine the existence of a specific sociocultural awareness in research papers; b) to identify the cultural aspects that were considered essential by the LAs in this program and show the strategies used to provide information; and c) to compare findings considering the theoretical background. The method will rely on a mixt approach considering quantitative and qualitative analyses and will be specific for each of the objectives.

ABSTRACT: The growing worldwide demand in the pulp market has fostered research that evaluates alternative fiber sources with specific characteristics that attend the needs of the consumer market, with a view to add value to the final product and reduce production costs. Acacia mearnsii De Wild wood is a by-product of the extraction of tannin from the trunk bark, used for firewood, charcoal and pellets. However, its wood is still poorly studied, especially its anatomical characteristics, which can provide important information about its industrial potential. This study evaluated the anatomical characteristics of Acacia mearnsii wood for the production of pulp and paper. Ten trees at approximately seven years old were cut down, five from the seed production area (SPA) and five from the clonal population area (CPA). From each tree, one trunk disc was sectioned at the diameter at breast height (DBH), resulting in 10 (ten) wood samples. From each disc, a sapwood specimen was made oriented in the tangential longitudinal, radial longitudinal and transversal planes, for later obtaining the anatomical cuts and the macerates. The anatomical description of the wood followed the recommendations of the International Association of Wood Anatomists-IAWA. From the dimensions of the fibers, their quality evaluation ratios for the production of pulp and paper were calculated. Results obtained from the anatomical characterization allowed to conclude that the Acacia mearnsii woods from SPA and CPA are indicated as a source of raw material for the pulp and paper production.

There have been new facets of multilateralism, which have motivated the realignment of traditional power relations established globally, especially regarding the United States and China. This new strategic environment can be observed in changes made to the Brazilian National Defense White Paper (LBDN) of 2020, as well as in the dialectic between white papers of the United States (2017), and China (2019). To investigate these realignments and their possible impacts on the Brazilian defense sector, the analysis was carried out in two phases: (1) analysis of the general characteristics of the Defense White Papers by the USA and China; and (2) comparison of discourses conveyed in chapters on international cooperation in each Defense White Paper. Speech patterns were analyzed according to rationales of Lexical Semantics and Critical Discourse Analysis. As a result, elements of semantic fields, intertextuality and modality in discourse were pointed out as parameters that could contribute to the evaluation of cooperation and deterrence/dissuasion actions to be adopted by the USA and China in the 21st century.

Mitigation of fungal biodeterioration on paper documents and artworks represents a challenge to conservators worldwide. Numerous lists of fungal species have been identified from paper collections, but are those species responsible for the respective biodeterioration phenomena or just environmental contaminants? The present work was aimed at obtaining an association between specific fungal stains and causative fungal species. 23 stains from three paper documents were sampled. Fungal structures observed in situ with optical and scanning electron microscopy were compared with the identification of isolates by molecular biology tools. Correlation between the observed fungal structures and the identified fungal isolates was achieved, varying from 13% to 64% of the samples within the three studied documents. Grey/black and dark brown stains were associated with Chaetomium globosum, C. murorum, Penicillium chrysogenum, P. commune, Myxotrichum deflexum and Stachybotrys chartarum. Eurotium rubrum was isolated from a foxing stain and Penicillium citrinum was identified on light orange stains.

This study investigates the linguistic organization of the introduction sections of academic papers from the Veterinary Medicine field in terms of the two basic systems that determine how one clause is related to another: taxis (degree of interdependency) and logico-semantic relation (Halliday; Matthiessen, 2014, p. 438). All the clauses from the introduction sections of five published academic papers were analyzed. The results showed a high recurrence of simple clauses and embedded clauses in the corpus. In the clause complexes, the preference is for paratactic extensions. The results of this analysis may help understanding the functioning of academic writing in English language in this specific field.

Cardiovascular (CV) guidelines stress the need for global intervention to manage risk factors and reduce the risk of major vascular events. Growing evidence supports the use of polypill as a strategy to prevent cerebral and cardiovascular disease, however it is still underused in clinical practice. This paper presents an expert consensus aimed to summarize the data regarding polypill use. The authors consider the benefits of polypill and the significant claims for clinical applicability. Potential advantages and disadvantages, data regarding several populations in primary and secondary prevention, and pharmacoeconomic data are also addressed., (Copyright © 2023 Sociedade Portuguesa de Cardiologia.

Abstract The study extends the conversation on the effect that co-authorship has on the citation impact of papers by analyzing the short-term advantage of co-authored papers. The results suggest that co-authored papers have a higher short-term impact than single-authored ones in all scientific domains. The study adds insights on the use of the immediacy index as an alternative indicator to evaluate the short-term competitive advantage of co-authored papers concerning the number of citations they attract. Furthermore, the study shows the efficacy of the immediacy index in comparing the short-term impact of different groups.

The pulp and paper sector has a notable highlight in the Brazilian economy, contributing significantly to the trade balance, job creation and investments. Currently, the sector basically uses wood from two genus to produce pulp for the short fiber and long fiber segments, Eucalyptus and Pinus, respectively. However, it's essential to study new raw materials, which may arise as an alternative to those already consolidated. In this sense, the objective is to evaluate the properties of Liquidambar styraciflua wood for the pulp and paper production. For this, five 7-year-old trees were used, from which discs were extracted along the trunk to evaluate the basic density, chemical composition and morphology of the wood fibers. The mean and weighted basic density values obtained for L. styraciflua wood were 0.482 and 0.484 g/cm², respectively, which allowed classifying it as medium density, a value close to that of other hardwood species used for pulp production. Regarding the chemical composition, low levels of ash (0.29%) and lignin (24.71%) and high levels of holocellulose (70.88%) and extractives (4.40%) were observed. As for the morphological characterization of the fibers, the mean values of length of 1.82 mm, width of 27.84 µm, lumen diameter of 16.10 µm and wall thickness of 5.87 µm were observed. In addition, mean values of 42.60%, 57.40%, 0.77 and 65.22 were obtained for the parameters of wall fraction, flexibility coefficient, Runkel index and felting index, respectively. In general, based on the physical-chemical-anatomical characteristics obtained for the L. styraciflua wood, it's concluded that it has aptitude for the pulp and paper production.

L’objectiu d’aquest article és estudiar la importància que té l’arxiu com a eina de construcció d’una identitat nacional i si a través de la seva organització es pot veure si la dita construcció nacional ha estat reeixida o no. En aquest sentit, s’agafa l’exemple de l’Arxiu Històric Nacional d’Espanya i s’analitza des de l’organització dels primers arxius en territori espanyol fins a la construcció de l’Arxiu Històric Nacional a finals del segle xix. Mitjançant aquesta anàlisi també es posa en relleu el paper que va tenir la Història en la formació de la identitat nacional i la seva interrelació amb l’arxiu. Una ciència no podria ser sense l’altre.

Heart failure (HF) with reduced ejection fraction (HFrEF) is associated with high rates of hospitalization and death. It also has a negative impact on patients’ functional capacity and quality of life, as well as on healthcare costs. In recent years, new HFrEF prognosis-modifying drugs have emerged, leading to intense debate within the international scientific community toward a paradigm shift for the management of HFrEF. In this article, we report the contribution of a Portuguese HF expert panel to the ongoing debate.Based on the most recently published clinical evidence, and the panel members’ clinical judgment, three key principles are highlighted: (i) sacubitril/valsartan should be preferred as first-line therapy for HFrEF, instead of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker; (ii) the four foundation HFrEF drugs are the angiotensin receptor/neprilysin inhibitor, beta-adrenergic blocking agents, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter 2 inhibitors, regardless of the presence of type-2 diabetes mellitus; (iii) these four HFrEF drug classes should be introduced over a short-term period of four to six weeks, guided by a safety protocol, followed by a dose up-titration period of 8 weeks. Resumo: A insuficiência cardíaca (IC) com fração de ejeção reduzida (ICFEr) está associada a níveis elevados de hospitalização e mortalidade. A ICFEr também tem um impacto negativo na capacidade funcional e na qualidade de vida dos doentes, bem como na despesa em saúde. Nos últimos anos, surgiram novos medicamentos modificadores do prognóstico da ICFEr, originando um intenso debate na comunidade científica internacional em relação a uma mudança de paradigma para o tratamento da ICFEr. Neste artigo, relatamos a contribuição de um painel de especialistas portugueses em IC para o debate em curso.Com base na evidência clínica publicada mais recentemente e no julgamento clínico dos membros do painel, três princípios-chave são destacados: (i) sacubitril/valsartan deve ser preferido como terapia de primeira linha para a ICFEr, em vez de um inibidor da enzima de conversão da angiotensina ou um bloqueador do recetor da angiotensina; (ii) os quatro medicamentos básicos para a ICFEr são o inibidor do recetor da angiotensina e da neprilisina, os agentes bloqueadores beta-adrenérgicos, os antagonistas do recetor mineralocorticoide e os inibidores do cotransportador sódio-glucose 2, independentemente da presença de diabetes mellitus tipo 2; (iii) essas quatro classes de medicamentos para a ICFEr devem ser rapidamente introduzidas num período curto de 4-6 semanas, seguindo um protocolo de segurança, e depois tituladas durante as oito semanas seguintes.

La Formación Inicial Docente es una etapa clave de la trayectoria formativa en que se construyen distintas representaciones sobre lo que es ser profesor y evaluador; presentándose la evaluación como contenido y competencia profesional. Sin embargo, aunque se alberga la expectativa de una evaluación orientada al aprendizaje, en Educación Superior prevalece la función sumativa y la hetero evaluación, con escasa participación de los sujetos evaluados (futuros profesores) durante el proceso evaluativo. En este marco, se realizó un estudio transversal de tipo descriptivo, con 41 estudiantes de Pedagogía Básica de una universidad del centro sur de Chile, con el propósito de identificar, a nivel de percepción, qué opinan del uso de One Minute Paper. Los resultados muestran una valoración positiva de la experiencia por parte de los sujetos bajo estudio, al favorecer el aprendizaje activo y la participación, y se alude al tiempo como principal factor obstaculizador.

This data paper presents the creation of a database bringing together all the French municipalities while giving a specific place to those which have undergone a merger process between 2012 et 2022: "the new municipalities" (communes nouvelles). Potential data gap and consistency issues arise with the creation of these new territorial entities aggregating municipal mergers. Using data from official statistics (INSEE - National Institute for Statistics and Economic Studies - and IGN - National Geographic Institute), this paper describes a process of compilation and aggregation of data. The method is detailed here, to allow its reproducibility.

This article seeks to contribute to the discussion about the role of online media in cases of public interest, in this case a financial political scandal (Thompson, 2001). For this, it was inquired into how it becomes visible (Thompson, 2001 & 2005), through Twitter, the link between the presidential candidate Sebastián Piñera and the scandal over tax havens, in particular, the case of the ‘Panama Papers’. The months of the presidential candidacy were set as the time limit, concluding in the first round of the presidential elections in Chile (between March 21 and November 19, 2017). It was concluded that on Twitter the scandal is visible through three main acts: discredit, face and take position, and two secondary acts, placed between them: unmask and federate. In this sense, social networks allow us to establish a space for questioning current democracies, for interaction with other “traditional” communication media, and ultimately to debate issues that affect citizens, as in this case the creation of Companies in tax havens by a former president and current presidential candidate. As Cardon (2010) points out, Internet expands the public space, transforming the nature of democracy.

El present article analitza la relació epistolar entre el doctor Joan Solé i Pla i Josep Subirà Puig, dos familiars que des de Barcelona i Madrid es van comprometre amb l’ajut material i la promoció dels voluntaris espanyols i catalans a les files de la Legió Estrangera francesa durant la Primera Guerra Mundial. A través de la seva correspondència busquem analitzar les projeccions nacionals en disputa dels discursos sobre els voluntaris i comprovar una qüestió escassament treballada: la important cobertura i organització de la propaganda sobre els voluntaris impel·lida per Josep Subirà, qui, malgrat tot, va mantenir amb Solé i Pla una relació estreta marcada per la cordialitat familiar i l’entusiasme per les mútues activitats aliadòfiles.

No puede negarse que los llamados a publicar o Call For Papers (CFP), utilizados de manera sistemática por las llamadas revistas “depredadoras”, son importantes para las revistas de excelencia y las de segundo orden que recurren a estos anun¬cios para sus ediciones regulares, temáticas y conmemorativas. En este artículo, se exponen los resultados de una encuesta realizada en 2016 a 199 editores de revistas científicas colombianas de áreas como Ciencias Naturales, Ingeniería y Tecnología, Ciencias Médicas y de la Salud, Ciencias Agrícolas, Ciencias Sociales, Humanidades y Multidisciplinarias. 143 de las revistas estudiadas (75%) tienen una periodicidad semestral; 53 editores participantes suelen usar los anuncios de CFP con el objetivo de llamar artículos para sus ediciones regulares. De ellos, 30% (114) de los editores utiliza el sitio web de la revista para difundir sus anuncios de CFP y el 29,5% (111) el correo electrónico. Sin embargo, 66 editores no respondieron a qué tan efectivos resultaron estos anuncios para atraer artículos, al no poder determinar el porcentaje de recibidos que fueron publicados = It cannot be denied that the call for papers (CFP), used in a systematic way by the ‘predatory’ journals, are important for journals of excellence and second-class ones that turn to these announ¬cements for their regular, themed and commemoratives editions. In this article we show the results of a survey carried out in 2016 to 199 editors of Colombian scientific journals of areas such as Natural Science, Engineering and Technology, Medical Scien¬ces, Agricultural Sciences, Humanities, and Multidisciplinary Sciences. The 75% (143) of the studied journals have a biannual regularity. 37.7% (53) of the editors usually use the CFP announcements to call for articles for their regular editions. 30% (114) of the editors use the journal’s web page to issue their CFP announcements and 29.5% (111) use the e-mail. Nonetheless, 66 editors could not answer how effective were these announcements to draw articles, because they could not define the percentage of the material received that was finally published.

Writing Studies scholars have raised concerns about framing student struggles to integrate secondary sources as an ethical problem of plagiarism. They propose, instead, framing student citation practices as transitional markers of development in which students use patchwriting to learn the discursive norms and values of academia. Patchwriting as a literacy tool for transfer of knowledge raised questions for me about whether students develop other scaffolds to aid in learning transfer. In this pilot study, I investigate student use of anchor sources, the “perfect source” that frames a student’s central argument, rhetorical structure, and/or purpose. Based on a random sample of a nationwide corpus of First-Year Writing research papers from 16 US institutions, findings show that 21 of 30 research papers (70%) revealed evidence of an anchor source. Six of the 9 papers without anchor sources show evidence of significant rhetorical problems. Results suggest evidence of knowledge transfer, as well as pedagogical implications for supporting this transitional stage in student development.

ABSTRACT Sugarcane bagasse, a waste material generated by the sugar-alcohol industry, is rich in lignocellulosic components such as cellulose and hemicellulose. The bagasse can be employed as a raw material in the pulp and paper industry, but is currently rarely used for this purpose, due to the availability of traditional sources such as Eucalyptus and Pinus. The objective of this work was to compare the physical and mechanical properties of papers produced using the cellulose extracted from sugarcane, Eucalyptus, and Pinus by the Kraft method. Four paper samples were produced using cellulose obtained from the following fiber sources: (I) 100% sugarcane bagasse; (II) 100% Eucalyptus; (III) 75% Eucalyptus + 25% Pinus; (IV) 75% sugarcane bagasse + 25% Pinus. Physical and mechanical tests were performed based on regulatory methodologies of the paper industry. The results indicated that the physical and mechanical characteristics of the paper produced from the sugarcane cellulose were similar to those of the traditional paper produced using Eucalyptus. Particular features such as good tearing resistance and tensile strength, as well as increased porosity and moisture, could be adjusted according to the intended use of the paper. Therefore, sugarcane bagasse can be considered a sustainable alternative to Eucalyptus and Pinus for the production of high quality paper, adding value to this agricultural residue.

This paper aims to carry out a diachronic analysis of Brazilian scientific productivity in the Library and Information Science field as indexed by the Scopus database for the period 1986-2015. We also analyze the main journals that publish Brazilian contributions, compare the impact of Brazilian production between papers published in Latin language journals and those in English, and identify the primary language of Brazilian papers and the main collaborating countries. We carried out a search on Brazilian scientific productivity in the analyzed field in the Scopus database for the studied period. Then, through a manual filter, we identified a corpus of 1,195 papers. Of the 90 journals identified, 26 journals were considered the main venues for Brazilian Library and Information Science research. These were grouped using multivariate cluster analysis. The main collaborating countries were grouped based on normalized values of co-authorship using Salton's cosine measure. Since 2006, Brazilian scientific production has experienced a similar growth tendency as the rest of the world. We observed that Brazilian journals, publishing in Portuguese, formed a cluster, while English and Spanish language journals clustered separately. We observed that papers published in English received on average more citations than those papers published in other languages.

This paper discusses 286 proposals and reports of Green Chemistry (GC) teaching experiences, in papers of the Journal of Chemical Education (JCEd) until 2019. The analysis was based on previous categories: source-problem, paper focus, subjects/area of knowledge, target groups, GC contents, type of approach and purpose(s) of the proposal. A list of possible characteristics of each category served as an example to compare with the information resulting from the analyses, and thus improve the discussions. In 127 papers, GC and its teaching were associated, albeit generally, with the theme of sustainability/sustainable development, which points to its potential to face environment-related aspects of chemistry in teaching. A systemic vision in the interconnection between GC and sustainability/sustainable development appeared more explicitly in 39 papers up to 2019. So far, the analysis highlights a certain reproduction of traditional chemistry teaching, and little evidence of the particularities of GC teaching. Despite the intention of inserting GC into chemistry teaching, proposals for its incorporation are often made superficially, more as an addendum or an extra quality than a specific goal. More methodological detail of the experiments carried out is needed to help in the dissemination of GC in the training curriculum of chemists. The discussions and reports on teaching approaches based on Systems Thinking showed the opening of a promising new methodological challenge within this theoretical paradigm.

Conservation environment with high humidity content or exposure to liquid water are directly linked to degradation of cellulosic materials, such as paper and fabrics. This research had as main objective the development of formulations based on two water-repellent products commercially available: a fluoroacrylic co-polymer and a polydimethylsiloxane. The purpose was to test their applicability to paper and textiles, both ancient and modern. Different analytical techniques have been used: FTIR-ATR spectroscopy, colorimetric analysis, observations by SEM-EDX and light microscopy, contact angle measurement and mechanical strength. Applications were carried out by spray and immersion achieving a systematization of the method and the choice of non-toxic solvents. Two of the four formulations tested were prepared with the addition also of silica nanoparticles. The results highlighted the compatibility and effectiveness of fluoroacrylic polymer with low nanosilica percentages applied by immersion.

Paulo Freire is the most cited author in bibliographic references of papers in the Brazilian area of Science Education destined for teacher training. However, analytical-contextual knowledge on this is lacking and still requires further investigation. For example, what would be the profile of the citations? In which types of citations does Freire appear? For what purpose? Why? To answer most of these questions, this study aims to analyze Paulo Freire citations in papers from the Brazilian area of Science Education. We carried out a Bibliometric survey where we analyzed citations. We researched five journals: Ciência & Educação, Ensaio Pesquisa em Educação em Ciências, Investigações em Ensino de Ciências, Revista Brasileira de Pesquisa em Educação em Ciências, and Alexandria: Revista de Educação em Ciência e Tecnologia. If Freire's ideas have been challenged within the restricted environment of a few political parties in Brazil, in the area of scientific knowledge there was an opposite effect: in research on teacher training in the Brazilian area of Science Education, Paulo Freire's theoretical and methodological contributions prevailed quantitatively and qualitatively in citations characterized as organic, conceptual, evolutionary and confirmatory.
