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.

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.

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]

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.

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.

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]

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 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 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]

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]

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]

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.

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]

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.
