During the first decades of the 20th century, the supply of paper for the printing industries in Mexico became a problematic issue. Production difficulties, price increases and poor distribution during the monopoly of the San Rafael factory started a deep debate on the modernization and interference of the State in the paper industry. This article analyzes the transition between the private monopoly and the creation of the public company, Productora e Importadora de Papel Sociedad Anónima (PIPSA) in 1935, during the government of Lázaro Cárdenas (1934-1940). Through parliamentary debates, press articles and ministerial reports, the questioning of the monopoly as a public policy, the birth of PIPSA and the results in its first years of operation will be explained.

La transición hacia el uso del papel para la enseñanza de la escritura en las escuelas elementales públicas en México no fue sencilla. Al finalizar el siglo XIX, se había cuestionado el uso de las pizarras por el riesgo que representaban para la salud, pues muchas veces los estudiantes borraban sus escritos con saliva y el material con el que estaban fabricadas no siempre guardaba las especificaciones necesarias, además el ruido al escribir era insoportable. En cambio, el papel, desde el punto de vista higiénico, pedagógico y estético, fue considerado un material superior frente a la dureza de la pizarra, el brillo de la superficie y la poca precisión que se obtenía en el trazo de las letras. Derivado de este planteamiento, se vislumbró seriamente la posibilidad de la adopción de papel en las escuelas oficiales. Sin embargo, este material era escaso y muy caro. Hacia el cambio de siglo, sólo dos fábricas de papel podían surtir a las escuelas y era necesario que abarataran el precio, que el sistema de distribución garantizara el abastecimiento y que el suministro fuera continuo. Este artículo analiza el inicio del proceso de reconversión de una tecnología para la enseñanza como era la pizarra por el papel. Analizo el gasto que significó y cómo esta modificación fue resultado de una multiplicidad de relaciones sociales, culturales, económicas y políticas que se entrecruzaron para dar una nueva configuración del tiempo, el ruido y los valores establecidos en el salón de clases. The transition to the use of paper in public elementary schools in Mexico was not easy. At the end of the nineteenth century, the use of slates had been questioned due to the health risk they represented since students often erased their writing with saliva and the material with which the slates were made did not always meet the necessary specifications. On the other hand, paper, from a hygienic, pedagogical and aesthetic point of view, was considered a superior material compared to the hardness of the slate, the shine of the surface and the lack of precision obtained in the tracing of the letters. Derived from this approach, the possibility of changing materials in official schools was seriously envisioned. However, the paper represented a very high cost. Only two paper mills could supply the schools and it was necessary to lower the price, and guarantee the supply by enhancing the distribution system. This article analyses the beginning of the conversion process of a technology for learning to write such as the slate for paper. I analyse the expense that it meant for the authorities and families, how the change was the result of a multiplicity of social, cultural, economic and political relations that intersected to give a new configuration of time, noise and established values in the classroom.

In this paper, I analyse the unpublished correspondence between Camilo José Cela and Cesáreo Rodríguez-Aguilera, consisting of 390 documents written between 1957 and 1998. This collection has been housed at the General Archive of the University of Jaén (Cesáreo Rodríguez-Aguilera Foundation) since 2002, and it includes letters from other recipients. This correspondence is not only of biographical interest but is also significant for the literary creation history of both correspondents. It contributes to the study of Spanish intellectual life during the second half of the twentieth century, especially the context woven around the magazine Papeles de Son Armadans. Surrounding the publication, beyond its challenges with censorship, a network of collaborations and various editorial projects (on Pablo Picasso, Salvador Dalí, or Rafael Zabaleta, among others) is established, as is evidenced in this correspondence.

The main editors of Clarín's La Regenta (Sobejano, Oleza, and Martínez Cachero) declared that they could not identify a literary reference in Chapter 2 of the novel. In this paper, I identify said reference and offer a hypothesis of its significance in understanding one of the novel's main characters, the Magistral Fermín de Pas. [ABSTRACT FROM AUTHOR]

Of all the public tributes dedicated to Antonio Machado in Spain during the Franco dictatorship, 'Paseos con Antonio Machado' (Baeza, Jaén, 1966) is perhaps the one which has elicited more literature, mostly of a memorialistic kind, due to the special circumstances in which it took place. Most accounts of the event speak of a frustrated homage, since the Francoist authorities banned it at the last minute. In this article, drawing from the information provided by more than a hundred new documents found in the Caballero Bonald Foundation, special attention is paid to one of the aspects of the tribute that has barely been dealt with in the existing bibliography on the subject: its international projection. Through the use of epistolary, archival and journalistic sources, the international repercussion of 'Paseos con Antonio Machado' is examined and a reconsideration is made of the success or failure of the tribute in light of the objectives pursued by a cultural event that should be framed within the context of the anti-Francoist struggle.

Critics have abundantly pointed out that the Sátira de infelice e felice vida de don Pedro de Portugal makes abundant use of Alonso Fernández de Madrigal's Diez questiones vulgares , which are in turn an extract from his monumental Comento a Eusebio. The present work deals with the detailed comparison of these three texts from the mid-fifteenth century; the result of this observation shows that don Pedro is following, with notorious fidelity, the text of the Questiones , in a closeness that he never maintains with the Comento , and therefore the former is necessarily his source. However, in these same glosses the constable presents information that is absent in the former and clearly comes from the latter. We propose as a hypothesis the existence of an intermediate text by Madrigal between the two texts we are working on, now lost, which served as a source for the Condestable. [ABSTRACT FROM AUTHOR]

Objective: To describe the characteristics of papers presented at medical student conferences of Sociedad Científica Médico Estudiantil Peruana (SOCIMEP - Peruvian Medical Student Scientific Society) between 2017 and 2019, as well as the factors related to their publication. Materials and methods: An observational, cross-sectional, bibliometric, retrospective and secondary-source study based on the books of abstracts of papers presented at scientific conferences between 2017 and 2019. The data were analyzed with the Stata Statistical Software: Release 13 using descriptive statistics. In the multivariate analysis, prevalence ratios were calculated with a 95 % confidence interval and p < 0.05 in the crude and adjusted analyses. Results: From a total of 447 papers, 170 (38.0 %) were completed research studies, 168 (37.6 %) research protocols and 109 (24.4 %) case reports. In addition, 233 (52.1 %) authors came from a university in Lima and 183 (40.9 %) were from public universities. Moreover, 376 (52.1 %) papers had an advisor among the authors, 332 (88.3 %) of whom were physicians. The frequency of publications accounted for 11.4 %. The prevalence of original-article publications was 131 % higher (aPR: 2.31; 95 % CI: 1.22-4.37, p = 0.010) and 63 % lower (aPR: 0.37; 95 % CI: 0.17-0.81, p = 0.014) among papers presented in 2019 compared to 2017, thus being statistically significant, with p < 0.05. Conclusions: One out of 10 abstracts of papers presented at SOCIMEP conferences was published; however, this number is still low. Among the factors associated with the publication were presenting a research paper as an original article and in 2019. The results of this study will help the university leadership to strengthen research through strategies and/or programs linked to the student scientific production. [ABSTRACT FROM AUTHOR]

In this article we study the particularities of editorial practice in contexts of confinement in Argentina through the systematization and analysis of five publications, already published or in the process of being published, which were formulated within the framework of pedagogical-political practices carried on by the Prisons Extension Program of the Philosophy and Literature Faculty of the University of Buenos Aires. These five cases will be addressed in order to observe what meanings guide the editorial processes through the marks imprinted on them by the specificity of the writing that summons them and the territory to which they belong. Publishing in the context of a pedagogical project developed by the university configures collective territories where writing and publications can display and carry plural voices, which are strengthened in that plurality forged in the heat of individual and collective subjectivation processes made possible by education and writing. Editorial practice is inseparably intertwined with actions aimed at defending rights, narrating lived experiences and building a collective history which are part of the desires and expectations regarding publication.

On 26 October 1776, Pedro Rodríguez de Campomanes presented to the Real Sociedad Económica Matritense de Amigos del País (RSEMAP) the Memoria sobre el reconocimiento y coordinación de las memorias que se van a publicar en cumplimiento de nuestros estatutos , a little-known text that established the method of reviewing the society's reports prior to their publication. Here we analyse the protocol of the process and the review criteria proposed by Campomanes to the RSEMAP, and, considering that his report is contemporaneous with the implementation in 1769 of the new process of governmental censorship, it is studied in its context and in that of the theoretical texts generated in the wake of the failed Mesa Censoria of 1770.

This study assumes that Franco's censorship was not limited to modifying or silencing those novels that did not adapt to ideological standards, but that it appropriated them to form a new literary system. Following previous studies, the aim is to establish under what form Céline's Voyage au bout de la nuit (1939) arrived in 1973. The distinguished and highly controversial author, who continues today to stir French literary memory, was banned in Spain until 1968 when his first novel appeared. The text under study, as corrosive as it is subversive to the official values in force, had to wait 40 years before it crossed the control established by the regime. A meticulous textual analysis and the study of the files of the General Archive of the Administration allows us to unravel the reasons why this novel evaded Franco's censorship.

In this paper the characterization of the work of art as a map of intensity, as proposed by Gilles Deleuze in his essay What the children say (gathered in Critique et clinique), will be analyzed. Art’s cartographic aspect is linked to the concept of deterritorialization and the Body without Organs that the philosopher, along with Félix Guattarí, develops in Thousand Plateaus. Thus, the art-cartography represents the becoming-world of the subject that transits the Body-without-organs and the intensive differences that populate the desert of multiplicity. Each way travelled is descripted by an artistic map where the haecceities and the thresholds of flows that pierce through the disorganized bodies are portrayed. The map of intensity would be the cartographic representation of the haul travelled by a subject immersed in a hodologic space, being every line of the map a journey within an intensive space [ABSTRACT FROM AUTHOR]

This essay studies the cultural consequences that the spread of paper money had in late nineteenth-century Brazil. First, I examine how these tensions are called into question through the analysis of a political scandal that took place in Rio de Janeiro, in 1900, concerning a two thousand reales banknote. Second, I offer a close reading of Machado de Assis' "Anedota pecuniária", a short-story included in Histórias sem data (1884). My goal is to interrogate the relation between paper money and the economy of credit work, and the narrative devices of literary fiction. [ABSTRACT FROM AUTHOR]

In Quevedo's so-called musa décima , the poetry not published in the posthumous editions of 1648 and 1670, there are poems with a limited textual history, reduced to one or two testimonies. This article looks at some of them copied only in two manuscripts from Santander and Palma de Mallorca (M-139 and MA22-3-06, respectively). In particular, it examines the variants of some anti-Gongorina satire, two epigrams in imitation of Martial and two poems against a prostitute and an old witch. The study detects errors and proposes possible amendments to the text of the modern editions. [ABSTRACT FROM AUTHOR]

This work examines the poetry collection Junín (1930) by the Peruvian author Enrique Bustamante y Ballivián (1883–1937). While a part of the Latin American avant-garde expresses a fascination with the rise of new machines in the metropolis, this article demonstrates that Bustamante y Ballivián responds to this trend by representing machinery of a different kind – extractivist machinery – in a different type of space: the Andes. The author also engages with the indigenista avant-garde poetic proposals of his Peruvian contemporaries. Unlike them, the poet does not aim to give voice to the indigenous subject, nor does he idealize or solely link it to nature. Instead, he portrays it as 'coupled' to the mineral extraction machinery. Additionally, the poet depicts this machinery as invasive, contaminating and destructive to the landscape and its inhabitants. This work argues that Junín emerges as the first poetic representation of the ecological impacts caused by large-scale mining exploitation in the Andes. [ABSTRACT FROM AUTHOR]

During the dictatorship of Francisco Franco (1939–1975) Catalan literature suffered a terrible blow, mainly in the censorship of books published in Catalan. In this period of cultural repression, the objectives and characteristics of the mission of translating foreign poetry in the Catalan-speaking regions were determined by special socio-historical circumstances. This article presents a panoramic investigation into the dissemination of Chinese poetry in Catalan culture during the Franco dictatorship. The various aspects of the investigation and the period in which it was carried out have been studied: the publications, translation and editing, the motives of Catalan translators in carrying out their work and the influence of socio-historical elements on the dissemination of the translated poetry.

This work analyses the struggles with Franco's censorship that José María Castellet had to face when he embarked on three anthology projects that were decisive in the history of post-war Spanish poetry. The particular severity with which Nueve novísimos poetas españoles (1970) was received invites us to focus on this anthology, which, with qualities that should have made it more resistant, fell foul of censorship in a way that its anthological predecessors did not. On the one hand, reflection on this paradox leads us to venture hypotheses about the dynamics of the repressive body's actions. On the other hand, a thorough analysis of the censorship dossier of Nueve novísimos allows us to draw some interesting conclusions. It is true, for example, that the elliptical diction introduced by the novísimo poets protected the anthology from a much wider purge. However, the censorship actually practised, which polished the more obvious aspects of its insurgent vocation, was enough to alter the historical reception and, by extension, the historiographical significance of a book that was stubbornly denied its subversive substance. The discovery of an unpublished composition by José María Álvarez is certainly not the least of the surprises of the archival side of this research. [ABSTRACT FROM AUTHOR]

Titian's work has from the sixteenth century to the present day motivated an important series of literary allusions and ekphrastic or culturalist exercises. This study addresses, in a way that is unprecedented, a critical analysis of the presence of Titian and his work in Spanish Renaissance and Baroque poetry. A considerable number of great authors (from Gutierre de Cetina to Lope de Vega and Quevedo) show Titian's influence on their works over a wide range of literary themes and techniques. Within the field of study of the ancient relationships between painting and poetry, the texts selected in this work are important because they represent a first lyrical interpretation of the brilliant Venetian painter in Spanish literature, a precedent for the rich and heterogeneous contemporary poetics.

In 1753 the Arte de la lengva metropolitana del reyno cakchiquel o gvatemalico by José Ildefonso Flores, was published. This was the most complete, detailed and rigorous grammar of the colonial era that describes the language of the Cakchiquel. For this, and like other grammatical texts from the New World, the model of Antonio de Nebrija's Introductiones latinae (c. 1488) is used, which causes many problems for Flores since there are many differences between the two languages. Despite the importance of this grammar and its interest for Missionary Linguistics, it has been the subject of only brief and partial studies and investigations, which is why an exclusively linguistic work is necessary that describes and analyses its content in detail. This work describes and analyses the structure and content of the Arte de la lengva metropolitana del reyno cakchiquel o gvatemalico , the context in which it was composed and the sources that inspired it.

The article presents the topic of paper laboratories and science in the pen of early modern authors. The importance of knowledge as power and its relationship with the scientific revolution of the 17th century is highlighted. The creation of the Royal Society of London for Improving Natural Knowledge in 1660 and its relationship with Francis Bacon's empiricism are mentioned. During the Restoration period in England (1660-1689), women had greater participation in public and cultural life, thanks to the social and cultural openness promoted by the Charles II regime. The figures of Margaret Cavendish and Aphra Behn, two English authors who ventured into literature and science of the time, are highlighted. Both authors used satire to criticize the misuse of technology and science. In the article "A Soup of Amorphism and Extravagance: Science in The Emperor of the Moon," Behn's satire on science and the spectacular practices of the time is analyzed. The article also highlights the participation of women in scientific thinking and debates of the time. [Extracted from the article]

Introduction: The Ave Maria Casa Madre Eco-School has run the international Litter Less Campaign to reduce and prevent paper waste in our school. Paper waste has been monitored and weighted along the 2020/21 school year in every single classroom. This Eco-School methodology agrees to the didactical approach of an outdoor teaching set by Mr. Andres Manjon. Method: We have used a travel digital luggage weigh scale to measure each paper waste per classroom. All data have been collected on an Excel sheet. Results: We have collected 140 kg of paper waste along the school year. Primary School classrooms have achieved the heaviest waste (53 kg), followed by the Teachers´Lounges (50 kg), Secondary School classrooms (21 kg), Bachillerato classrooms (15kg), Basic Technical Education FPB (2 kg) and Preschool -Infantil (0 kg). Conclusions: The amount of paper waste and its quality have been certainly improved along the school year due to the implementation of the Litter Less Campaign. This project has encouraged students and teachers to a more responsible paper consumption at our EcoSchool. [ABSTRACT FROM AUTHOR]

Contemporary artistic practices were provided with a space for reflection and the creation of opinion in the galleries of the Fundació Espais and in the pages of its art magazine, Papers d'Art. A group of independent voices of multidisciplinary artistic production was made audible thanks to this publication that provided a critique which forged dynamic connections between artistic meaning and social and cultural contexts. This paper highlights a shift in meaning of the conception of contemporary art as a key element in intellectual culture, including politics, philosophy, science and other creative formats such as music and literature. Based on an analysis of the critical awareness of the various contributors to the magazine and on the historiographic study of certain aesthetic and symbolic questions, a review of the articles published in the Studies and Research section is detailed.

Transparency is one of the main quality requirements for wines, it is achieved mainly from the clarification process. Calcium bentonite is the most widely used clarifying agent to date and one of the most efficient in winemaking. Due to the economic situation that our country presents, it is not possible to import all the raw materials necessary for the production of wines, such is the case of bentonite. This research evaluates the use of nationally produced mineral zeolite as a clarifier in wine production processes. Turbidity was used as the response variable of the clarification process and was measured using a TURBIQUANT® 3000 IR/T Turbidimeter. In this process, mixtures with different proportions of imported calcium bentonite and national mineral zeolite were used, to evaluate the potential of the latter as a clarifier for wines produced in Santiago de Cuba. The best results were achieved using mixtures of imported bentonite and natural zeolite, sedimentation for ten days, and then filtration with filter paper with a pore size of 10 to 13 μm. The turbidity of the control ferment decreased by 92, 9 % from 60 NTU to 4,3 NTU with the pure zeolite and by 95,45% to 2,7 NTU using 75 % bentonite and 25 % zeolite. The results of this research show that it is possible to use the Cuban natural zeolite as a clarifier in the wine production processes. [ABSTRACT FROM AUTHOR]

The cyanobacteria Nostoc commune contains bioactive compounds with antimicrobial activity and high potential to control of phytopathogens. The objective of this work was to determine the in vitro effect of sonicated biomass of these cyanobacteria on the growth of Fusarium oxysporum. The biomass of N.commune was dissolved in sterile distilled water and subjected to centrifugation processes and ultrasound-assisted cell rupture. The antifungal effect was evaluated using the disk diffusion technique (Kirby-Bauer) in a PDA (Potato Dextrose Agar) medium. In the center of the Petri dish, an agar disk (0.7 cm) with pure mycelium of the fungus was placed in the center of the Petri dish and, around it, four filter paper disk impregnateed with the algae extract (0.7 cm) were placed. The radial growth of the pathogen was measured in the presence and absence of N. commune, until the control covered the entire Petri dish to assess the Percentage of Radial Inhibition of the pathogen (PICR %). The growth rate of the fungus was lower in the initial stages of measurement and the PICR fluctuated between 33 and 58%. However, there were no inhibition halos in the growth of the fungus, it is assumed that the antifungal effect of the cyanobacteria was not permanent over the time, but it could be potentiated by improving the extraction process of the extract.

The demanding promotion of university professors is being taken advantage of by international publishers to develop a fast business, that is framed in supposedly fraudulent activities of apparently scientific magazines, but without impact indexes that some experts already qualify as "epidemic" (García-Puente, 2019) and "plague" (Silva, 2016). This research uses the mystery client technique (Morena, 2013) to respond to an intentional sample of call for papers (CFP) submitted to researchers between January and April 2020, with a previously published article, that was intentionally altered to appear to be a scientific paper, but which violates the guidelines of originality and rigor: the order of the paragraphs is altered and translated into English with DeepL, without subsequent monitoring. During the period, 98 PICs were received and 38 submissions were made. The results are eloquent: none has been rejected, and within an average of 6 days 17 publication acceptances are confirmed. In all cases, payment is requested in advance. The article allows us to identify the profile of the journals, their recruitment strategies, the use of claims of: indexing, ethical standards and peer review and the naming strategies to simulate international prestige.

This article starts from the following question: how does playing enable learning from experiences that children create to escape the routines and prescriptions of the curriculum? To bring problematizations from this question, we developed an ethnographic investigation from a post-critical perspective in a municipal public school. The argument developed here is that children experiment, invent and create ways to play to escape the routine of school curricula, and thus learn by playing and play by learning. Based on the experiences that children themselves are exposed to, we understand that by exposing ourselves to the good affections they allow us to have, we also need, as teachers, to invent other times, intervals, durations, extensions to proliferate learning in school curricula, which escape of the rigidity and control given by the normative prescriptions that constitute many curricula.

Background and aims: The excellent physical and chemical properties of Abacá and Japan papers make them one of the most used materials in restoration of cultural assets on paper. The objective of this work is to characterize the fibers that compose them and identify plant genera or species that were used in their manufacture. M&M: Fibers from samples of each paper and previously collected reference plant material were disintegrated. The diagnostic characters of the fibers were observed with a photomicroscope and photomicrographs were taken. Subsequently, the homologous characters were compared by relating the Abacá paper fiber samples with those of Musa sp. and the Japan paper samples with Broussonetia sp. and Euonymus sp. Results: There were coincidences between the diagnostic characters of the paper fibers of Abacá and Musa sp. Regarding the Japan paper samples, there were results consistent with Broussonetia sp. but not with Euonymus sp. Conclusions: According to the results observed between the Abacá paper fibers and the samples of the collected living material, we infer that the Abacá paper contains fibers of Musa sp. In the Japan paper samples, the similarities observed between the diagnostic characters of the fibers with respect to the reference plant samples indicate the presence of Broussonetia sp. fibers. There is no evidence of fibers of Euonymus sp. [ABSTRACT FROM AUTHOR]

In order to achieve an increase in the profitability of tissue paper production, this research aimed to identify factors that affect the degree of pulp refinement and the tension index of the tissue paper when using short fiber, long fiber and Quimizine B enzyme. The methodology considered laboratory experiments, obtaining refining curves, multilevel factorial design and response surface diagrams. The results indicated that the most significant common factor in the pulp refining degree and tension index is the specific energy consumption for both types of fiber, and that optimal operating parameters can be known by analyzing the refining degree and tension index independently and simultaneously. It was concluded that the multilevel factorial design allowed to identify significant factors that influence the properties of the refining degree and the resistance of tissue paper when looking for an individual and simultaneous optimum and, that the influence of the enzyme increased the properties of the refining degree and the tensile strength of the paper when using raw material of short and long fiber from Eucalyptus globulus and Pinus radiata, respectively.

The main problem identified is the conventional way of distributing indirect manufacturing costs for the paper company dedicated to the process of converting paper, having generated distorted unit costs. Faced with this situation, the implementation of a costing model by activities was proposed. The main objective of this research is to establish procedures for the implementation of the costing methodology by activities for the paper industry. The methodological study is quantitative at a descriptive level where data collection was done in a simple random manner, for which documents were reviewed and analyzed, production processes were observed, and surveys were developed. The results confirmed the achievement of the objectives and hypotheses raised in the investigation, where it was indicated that there is a relationship between the activity-based costing methodology and the measurement of indirect costs in the paper industry. The investigation is concluded "Activity-based methodology is beneficial to apply in the calculation of indirect costs, with a new approach to calculating costing by activities that allows diversifying suitable inducers and applying them to the different activities related to indirect costs.

Amate (amatl) is a handmade paper of Mexico made by Otomi Indians. This craft is made from bark of tree bark amate or jonote. It is originally developed in the states of Puebla, Hidalgo and Veracruz especially in San Pablito, Puebla. However, amate paper is sold as background Nahua paintings by artists from the state of Guerrero. Amate paper paintings are a combination of Nahua and Otomi traditions. While there have been some minor innovations, the amate paper is still done with the same basic process used in the pre-Hispanic period by obtaining a classical amate tree bark fiber. This is negatively affecting the ecosystem of the North of Puebla and forcing vendors bark in search of other species, so it is necessary to make paper amate more sustainably, including new types of bark from other species and by-products of agro-industries such as rice, coffee sugar cane, and other types of fiber that have highavailability The objective of this work was to analyze and compare the Chemical pulp of coffee characteristics, as raw material for amate paper of higher quality than that produced from the bark of other species. The results showed that the structural and chemical characteristics of coffee pulp cellulose pulp showed ease of paper making, due to its properties of adherence, formation and agglutination of fibers similar to the high quality of the final product as the amate tree bark-derived paper.

Democracy is considered to be the ideal foundation of societies today. In a democratic society, news media play a highly relevant role as avenues by which public and political powers can interact with society and facilitate civic participation. The public’s perception of the news media’s reputation is a crucial factor for enhancing trust and citizen engagement. This article presents a study of the reputation of the media (paper press, digital press, radio and television) in ten European countries: Austria, Belgium, France, Germany, Italy, Poland, Portugal, Romania, Sweden, and the United Kingdom. A quantitative method was applied to the results of a survey conducted to determine the reputation of news media among a sample of the informed population in those countries (1,000 residents of legal age who used media at least two or three times a week). The concept of reputation is thereby characterized in its association with the media, identifying its integrating attributes and assessing its incidence in each type of medium. The results indicate that, although television is the most widely used medium, the printed press enjoys a higher reputation in most of the countries studied, being seen as having the attributes of credibility and informative rigor. This study provides a detailed analysis of the scores given to media reputation attributes in the considered countries. It also offers a ranking of the media with the highest reputation in the countries examined, as well as a description of the reputational position of each medium. [ABSTRACT FROM AUTHOR]

The objective of this work was to verify the potentiality from the pulps to the soda-antraquinona of pine for the production of papers wave, liner and newspaper (blended with trash pulp), using adapted technological outlines of one manufactures of trash pulps. The work was carried out with pine chips coming from the north area of Missions, according to a prosecution indicated by Tucumán paper mill. In the case of liner and wave, the reached yield was of 67 % and the results indicated that the used process (soda-AQ of pine, with impregnation of 25 % of the chips) it is adapted for the obtaining of pulp brown semichemical. The obtained pulp presented a quality more than enough to be used in the production of papers liner, being in the inferior limit of quality for the production of papers wave (130 g/m², RCT 1,56 kN/m, CMT 172 N). with regard to the periodic paper, the pulp with yield of 61 % was refined blended with trash pulp in different proportions and it was whitened with NaClO with an objective target of 70 %ISO. The best mixture was that of 90% of trash pulp and 10 % of pulp pine semichemical. [ABSTRACT FROM AUTHOR]

The psychometric properties of the Argentinian version of the ASSIST and its factorial invariance for two administration formats (paper-pencil and online), were analyzed. Two samples were employed. In one of them, the participants (n=700) completed the ASSIST in paper and pencil format, and in the other (n=835), they responded online. The model fit for both samples was tested obtaining adequate indices. A factorial invariance analysis then compared the model for the two administration formats, verifying adequate metric invariance. Furthermore, the internal consistency of the instrument dimensions for each sample was analyzed and compared. Results showed good coefficients. Finally, the comparison of dimension scores between the samples did not produce variations. The results and their practical implications are discussed. [ABSTRACT FROM AUTHOR]

The objective of the research was to analyze the role of machine data learning in systematic literature reviews. The Natural Language Processing technique called topic modeling was applied to a set of titles and abstracts collected from the Scopus database. Specifically, the Latent Dirichlet Assignment (LDA) technique was used, from which it was possible to discover and understand the underlying themes in the collection of documents. The results showed the usefulness of the technique used in the exploratory literature review, by allowing the results to be grouped by theme. Likewise, it was possible to identify the specific areas and activities where machine learning has been applied the most, in relation to literature reviews. It is concluded that the LDA technique is an easy-to-use strategy and whose results allow a wide collection of documents to be approached in a systematic and coherent manner, notably reducing the review time.

Paper machines consume large amounts of energy and in most cases savings are possible. The drying section in the paper machine has been structurally modified through 60 years of operation, with limited use of the heat recovery system. The objective of the work is to assess the opportunities for energy conservation, through the application of energy management systems in the paper factory.Methodologies are applied for energy balance and heat integration, taking into account the requirements specified by the Cuban standard ISO 50001 for energy management systems in terms of energy review. Pinch analysis is applied using HENSAD and Aspen Energy Analyzer computing resources. The proposed energy performance indicators constitute a reference for the definition of an energy baseline. Energy conservation opportunities are identified with a total annual saving of $ 48,902 that makes it feasible to execute a project of $ 35 546, whose capital cost is estimated to be recovered in 2 years.

This paper evaluates economically build a new cogeneration plant with clean energy from forest biomass company Norske Skog Bio Bio (NSBB). This is to show that this plant-based forest biomass for electricity generation is a viable option in Chile from the economic and environmental perspective. For this evaluation, we propose an approach that uses “real options theory" based on the application of log-transformed binomial method with six steps. Also, comparing the results obtained with this approach, the results using traditional methods. It is found that for all cases studied, the value yielded by the real options method was higher than estimated by traditional methods. It is concluded that this alternative profitable investment.

In 1848 Dr. Castro Madriz issued the decree which established the Republic of Costa Rica and its new coinage. An oak tree (Quercus sp.) was engraved on silver coins as a symbol of the strength and hospitality of the new Republic. These coins were minted between 1850 and 1862 (1/4, 1/8 and 1/16 of Peso) and between 1864 and 1875 (50, 25, 10, and 5 cents of Peso). This paper provides information on the significance of the oak tree in the socio-political context of mid XIX century Costa Rica. It also provides estimates of the number of pieces minted of each value for a total of approximately 1.871.000 coins. The quarter Pesos of 1853 and 1855 are scarce while the 50 cents of 1875 are relatively common, and all denominations with little wear are rare. The Q. salicifolia tree is similar to that engraved on the coins. After 1880 an oak branch was engraved in different issues of paper money, mainly as a crown for the head of Liberty. The last bill with this symbol was issued in 1943, with a value of 1 colón. [ABSTRACT FROM AUTHOR]

This paper shows the methodology and results of the evaluation of the cleaning system of a Kraft paper mill. This evaluation was made keeping in mind variables of that system such as the pulp stock consistency percentage, ash content, air level in the pulp stock, and differential of pressure through the cleaners, for the analysis of a series of samplings carried out during the production of the different paper grades. On the basis of the results, possible modifications or improvements of the cleaning system were proposed, which will allow a reduction in pulp and water losses, energy consumption, and the amount of air required in the paper machine.

This research study proposes a classification system to identify and prevent occupational accidents in fiber storage warehouses at a pulp and paper facility. The present analysis is based on variables including pedestrian circulation, bobcat, trailer trucks, access, pedestrian circulation zones, and handrails. The proposed methodology defines and trains the system by using occupational accident event data collected at the facility. Three different predicting algorithms are used: J48 decision-making trees, Naive Bayes, and Bayesian nets. The results show that the J48 decision-making tree algorithm accurately identifies possible occupational accidents 90% of the time. It is concluded that identifying variables involved in occupational accidents allows generating a C4.5 (J48) decision-making tree that can be used as a support tool to prevent occupational accidents.

One of the most important changes in the syllabus improvement is to achieve a more qualitative and comprehensive final evaluation in all disciplines, where interdisciplinary term papers are projected. Therefore, it was considered opportune to unify the term papers of Methodology of Investigation and Health Prevention subjects in the Medical Sciencies Faculty of Holguín, what imposes that professors of both matters act in the same way towards the orientation, follow-up and evaluation of this activity, reason why a guide that facilitates the orientation for work development to the students and criteria uniformity in the teaching staff to evaluate and diminish the subjectivity when granting a qualification was elaborated.

The main objective of this work is to highlight the relationship and importance that Document Management provides the environment as an element included in the use of good practices that contribute to paper savings and therefore sustainable development while taking into account the evidence as a reflection of the operations that any company develops. Also get to become aware of the benefits of being friendly to the environment through the reduction of paper consumption. The analysis - synthesis and cause-effect were used as a methodology. The main results achieved are reflected in the actions that have been developed in the Faculty of Economics through the execution of diploma works deployed in the Department of Business Studies served by the subject of Information Management of its IT discipline and work of the Master's Degree in Information Management in the Organizations of the UNESCO Chair in Information Management for Organizations. The software used in the development of the same was the ALFRESCO Documentary Management System for being free. Good practices of several organizations are analyzed, as well as the problems that paper spending brings to the environment. The result of these works has allowed the definition of the processes of the application of the Documentary Management for the control of the documentation of the mastery as well as of the Graduate School and other organisms of the state establishing a work culture that will allow as a conclusion, its application to other processes in the Faculty of Economics.

In this paper we present a classification of sources and the strategies used by writers of theses and research papers in order to identify a research gap in Humanities. Based both on a qualitative study and a corpus analysis, we aim to determine the variation of such communicative act (identifying a research gap) in theses and research papers in the Humanities. The results show that identifying a research gap is carried out in both genres, though it is more frequent in the theses, possibly due to its evaluative nature. Thus, regardless the genre, it is easy to present an own research gap (without the reference to other sources). Finally, data show that specific strategies for identifying a research gap in the Humanities are not the same in both genres that are analyzed. [ABSTRACT FROM AUTHOR]

Most of the national and international documentary heritage are on paper. From industrialization in the manufacture of such material, paper with acidity levels has been produced which, together with other factors, has been causing the deterioration of this type of documentary heritage. In recent decades, with the incorporation of new paper production processes this problem has been partly solved. The international standards organism ISO has drafted two rules in this connection: ISO 9706 and ISO 11108. With the spread and recommendation for the use of permanent paper for preservation of documentary heritage in the long term, it is essential to know the standards and be well informed. This article describes the variables in the manufacture of paper that influence the permanence of the papers. It also identifies the concepts and history that surround both ISO standards and the main characteristics and component parts of them. The annex provides a glossary of key technical terms used.
