Learning from the past: from incubation in ancient Egypt and Greece to modern hypnosis
Authors: Facco Enrico , Tagliagambe Silvano
Published: August 2021

The origin of hypnosis can be dated back to ancient philosophies and medicines. Incubation had been used in ancient Egypt and Greece for some three millennia with the same indications of modern hypnosis and was well-known by both Hippocrates and Parmenides. Then, it was dismantled by Christian hagiographic propaganda in 4-5th century AC and buried to the oblivion. Again, the birth of the new sciences in 17th century was the result of a compromise with Church, forcing them to limit their field of interest in the Cartesian res extensa only, leading to consciousness and mind-body relationship being neglected for political-religious will, rather than scientific grounds, and to Hippocrates’ teaching being betrayed. As a result, the history of hypnosis was marked by its outstanding results paralleled by misunderstanding and prejudicial refusal, a fact endowed with deep epistemological implications.
The Cause and Benefits of GDP
Authors: Bechtel Gordon
Published: August 2021

It has recently been shown that world GDP FP-Causes world life expectancy at birth, where FP denotes fractional polynomial (Bechtel, 2021).  This article shows that American and Chinese GDPs FP-Cause world life expectancy even more strongly than world GDP does.  These striking results beg the question: what FP-Causes American and Chinese GDPs?  The answer is globalization, which is also shown here.  Furthermore, it is demonstrated that American and Chinese GDPs also FP-Cause world literacy and employment rates.  It remains to be seen if the World Bank or International Monetary Fund can show that the GDPs of the other (less affluent) 18 nations in the G20 Fp-cause their country’s life expectancy, as well as their literacy and employment rates.  Yearly, pre-pandemic, within-nation increments in these variables can then be compared with subsequent decrements to assess an endogenous viral effect on each country’s well-being.  These comparisons will expose inequalities across nations due to the varying wealth of nations.  The results in this article are brought by Royston and Altman’s (1994) generalization of polynomial regression, which estimates both coefficients and their  powers.
A Discourse Analysis of Zuckerberg’s Pragmatic Identities’ Construction based on Adaptation Theory
Authors: Li Yuxin
Published: August 2021

People construct different pragmatic identities in everyday talk and the process of building identities usually adapts to the context. To be specific, entrepreneurs represents himself and the company when uttering to the outside society and the construction of entrepreneur’s identity is related to the company’s image. They are inclined to use intertextuality resources to build connection with the potential audience. Therefore, in this research, the author analyzed an entrepreneur’s speech discourse to describe what pragmatic identities are constructed and how does the construction adapt to the speaking context. To answer these questions, the author conducted a discourse analysis to illustrate relationship between the language use and physical, social and mental world based on Adaptation Theory. The results presented that the entrepreneur builds various master identities, interpersonal identities, and personal identities with intertextuality language resources to adjust to the speaking context. This study suggested that entrepreneurs are supposed to improve the skill of manipulating their discourse strategies to build close connection with potential listener.
The role of graphene/graphene oxide in cement hydration
Authors: Meng Shaoqiang , Ouyang Xiaowei , Fu Jiyang , Niu Yanfei , Ma Yuwei
Published: August 2021

Graphene (G) and graphene oxide (GO) have been shown to significantly improve the mechanical properties of cement-based materials. In this study, the effect of the G/GO on cement hydration was investigated. First, the zeta potential of G/GO in simulated solutions was tested, and the interaction between G/GO’s surface and Ca2+ was explored. Subsequently, scanning electron microscopy was used to observe the morphology of C–S–H nucleation and growth on the cement surface in the cement paste containing G/GO. Furthermore, XRD and TGA analyses were carried out on the hydration products of the sample. At last, isothermal calorimetry was applied to investigate the influence of G/GO on the early hydration of cement. The results showed that the addition of G/GO significantly accelerates C–S–H nucleation and growth on the cement surface. It is indicated that the high mobility ions derived by G/GO in the cement paste dominate the reason for the accelerated hydration of cement. The presence of G, especially GO, facilitates the mobility of ions, especially Ca2+, thus enhances the interaction between the cement surface and the ions. This strong interaction promotes the C–S–H nucleation and growth, and therefore, the hydration of the cement.

Yapılan çalışmalarda, WUV-C işleminin, UV-C sistemine kıyasla gıda yüzeyine inoküle edilen mikroorganizmaların dekontaminasyonunda daha etkili olduğu tespit edilmiştir. Bu çalışmada, su destekli UV-C sisteminin taze meyve ve sebzelerin dekontaminasyonunda kullanımı konusunda yapılan araştırmalar incelenmiştir.
Research on the mechanical behavior of the biomass densification process based on a thick-walled cylinder
Authors: Wang Yu , Sun Yu , Wu Kai
Published: August 2021

The mechanical behavior of the biomass densification process has noticeable influences on energy consumption and pellet quality. In the authors’ previous work, a method was proposed to determine the inner pressure by testing the circumferential strain of the outer die wall. Based on this method, a device was developed with strain gauges in the form of a single pellet unit. With this device, experiments were conducted with wood shavings, rice straw, and wheat straw under different levels of particle size, compression rate, and moisture content. The effects of these factors on the inner pressure were analyzed. The relationships among the inner pressure, pellet density, and specific energy consumption were obtained. Results showed that the pressure ratio increased linearly and then decreased and became constant during the relaxation period. The pressure change during the relaxation period was isotropic. The results could provide mechanical explanations for the phenomena in biomass densification processes.

Anaerobic digestion processes with biogas production are widely used for organic waste treatment with an emphasis on energy recovery. Some recent studies have demonstrated the influence of magnetism on microbiological activity. These indicate a possible influence on the efficiency of anaerobic digestion. Thus, technologies that act in anaerobic digestion enhancement can contribute to the improvement of treatment of organic compounds. The present study aimed to verify the influence of a constant electromagnetic field on the anaerobic digestion in anaerobic reactors fed with glucose (2 g/L) at 37 ± 2 °C. In each experiment, reactors were operated with a constant electromagnetic field of 5, 7.5, and 10 mT. The inoculum was granular sludge from an anaerobic treatment plant in a non-selective media culture. Biogas production, chemical oxygen demand (COD), and solids removal were measured during the experiment. Results showed differences in methane production of 21.5% and in COD removal of 15% in the tests with an electromagnetic field of 7.5 mT. These results signs for the viability of the application of a constant magnetic field as a biostimulation agent.

Authors: Han Mei-Ling , An Qi , He Sai-Fei , Zhang Xiao-Lin , Zhang Ming-Hui , Gao Xin-Hua , Wu Qian , Bian Lu-Sen
Published: August 2021

Solid state fermentation with different lignocellulolytic materials as inducers was used for lignocellulolytic enzyme production in this study. Pleurotus ostreatus strains were assessed by measuring laccase, CMCase, and xylanase activities. The secretion potential of the lignocellulolytic enzymes by wild and cultivated strains was analyzed for the first time. The wild and cultivated strain showed their unique capacities for secreting lignocellulolytic enzymes on solid-state fermentation with different lignocellulosic materials. The wild P. ostreatus strain preferred corncob for the secretion of laccase and xylanase activity, but the cultivated strain preferred poplar sawdust. The wild strain and cultivated strain showed a consistent preference for poplar sawdust for the secretion of CMCase activity. The wild strain was advantageous because it achieved the maximum hydrolytic enzyme activities within a short time period. Poplar sawdust and corncob were conducive to laccase secretion by the wild or cultivated strains and the rapid accumulation of laccase on solid-state fermentation. Additionally, continuous, stable laccase production was an extremely important advantage by solid-state fermentation of poplar sawdust, particularly in the wild strain. These findings are helpful in selecting the appropriate strain that corresponds to suitable lignocellulosic materials. The optimization of integrated industrial lignocellulolytic enzyme production can also be achieved.

Published: August 2021

The influence of soda-anthraquinone (AQ) pulping conditions on paper properties of oil palm empty fruit bunches was studied using Response Surface Methodology (RSM) based on Central Composite Design (CCD). The alkali charge, NaOH (A), pulping temperature (T), and pulping time (t) ranged between 20 and 30%, 160 and 180 °C, and 60 and 120 minutes, respectively. The mechanical properties evaluated for the handsheets produced were the tensile index, tearing index, bursting index, folding endurance, zero-span tensile strength, and the optical properties (brightness and opacity). The effects of soda-AQ pulping conditions on oil palm empty fruit bunch paper were elucidated by the regression models obtained. The optimum pulping condition were at 27.3% alkali charge, 160 °C, and 60 min that produced paper properties with 26.8 N.m/g tensile index, 7.95 mN.m2/g tearing index, 5.32 kPa.m2/g bursting index, 1.70 log10 folding endurance, 46.2 N zero-span tensile strength, 51.8% brightness, and 95.8% opacity.
Hydrolysis of abandoned bovine hair by pulping spent liquor and preparation of degradable keratin-based sprayable mulch film
Authors: Li Wenxin , Chen Yurou , Zhang Sufeng
Published: August 2021

Pulping spent liquor was used to hydrolyze abandoned bovine hair, and the resulting keratin hydrolyzate was blended with polyvinyl alcohol (PVOH), polyacrylamide (PAM), N,N-methylenebis (acrylamide) (MBA), and glycerol (GL) to prepare the low-cost degradable keratin-based sprayable mulch film (KSMF). The prepared KSMF contained elements required for plant growth, such as N, P, K, S, Ca, Si, and the water absorbency reached 380% in deionized water. A degradation of 23.1 wt% was attained while it was buried for 50 d in soil. The KSMF was easy to apply and needed to be diluted for spraying on the soil surface and formed a physical barrier to reduce evaporation of water and heat preservation. The KSMF had good degradability and entered the soil to become a high-quality biomass organic fertilizer during the growth of the crop, thus avoiding “white pollution” and realizing the recycling of waste, which would extend the application prospects in sustainable modern agriculture.

Published: August 2021

Xylotrophic fungi are well known by their ability to excrete enzymes into environment. These fungi have important biotechnological potential and some of them produce industrial enzymes. Besides, xylotrophic fungal species have recently attracted a lot of attention among researchers as a source of antibacterial drugs. Aim. To analyze the effect of the carbon source in the culture medium, as well as the conditions of deep cultivation on the mycelium yield, proteolytic, cellulolytic and antimicrobial activity of the culture liquid of Trichoderma atroviride. Methods. Deep culture methods were used, partial purification was carried out with salting and subsequent dialysis, the cellulolytic activity was determined spectrophotometrically, antimicrobial activity was determined using the disc diffusion technique. Statistical analysis was performed using STATISTICA 6.0 software. Results. The highest cellulolytic activity (0.50±0.03 units/ml), mycelium yield and the smallest colony diameter were detected when cellulose was used as a carbon source. However, the highest proteolytic activity of the culture liquid was observed with glucose as a carbon source. The optimal temperature range for hydrolase activity was shown to be in the range of 25-30 °C. In comparison with Pleurotus ostreatus, the culture liquid of T. atroviride not only has more pronounced antimicrobial activity, but also inhibits the growth of Candida albicans. Conclusions. The culture liquid of isolated strain T. atroviride is a promising source of hydrolytic enzymes that can be used in organic farming and industry. The purified preparation obtained from the culture liquid of T. atroviride showed significant antimicrobial activity and can be successfully used for drug development in the future.
Loan Asset Indicators and Commercial Bank Fragility in Kenya
Authors: Bwire Albert Camus Onyango
Published: August 2021

Purpose. To test the predictive ability of loan asset indicators on Commercial bank fragility in Kenya. 

Design/Method/Research approach. The study adopted positivism research philosophy with exploratory research design. The study population was 42 Commercial banks in operation on 31st December 2015. Secondary data was collected from Central Bank of Kenya and analysed using Stata Statistics/Data analysis. Generalised Linear Model was used to establish the relationship between asset indicators and bank fragility. The concept of credit creation was explored as the genesis of bank fragility. This study is part of early warning systems in detecting bank fragility.

Findings. The research found a direct relationship between a lagged dependent variable, loan portfolio growth, loan deposit ratio and bank fragility.

Practical implications. Recommendations are followed on the basis of this study. At first, regulator develop a potential solution to control loan portfolio growth, cap loan deposit ratio and limit the level of non-performing loans. Banking practitioners should model monthly reporting requirements to ensure that banks are able to disclose the ratio and explain any significant changes. Secondly, since Non-performing loans can act as an incentive for bank managers to seek deposits and lend more thereby exacerbating the problem, banks with NPL to gross loans greater than an upper threshold determined by the regulator should not be allowed to attract more deposits. Thirdly, set the maximum level of loan deposit ratio to avoid expensive, sensitive and high-risk loan capital. Implementation of these recommendations will lead to secured social welfare.

Originality/Value. The study examines the role of certain loan asset indicators on bank fragility and extends the discussion in the area of early warning systems and commercial bank instability in Kenya.

Research limitations/Future Research. This research contributes to the discussion on bank fragility and early warning systems. The further research should review evidence from other jurisdiction with high numbers of distressed institutions to determine how many months or years before distress the three significant variables could predict fragility. Besides, there is need for research on insider loans as defined and why there was no statistical significance.

Paper type. Empirical.

Authors: Guzmán Barrios Rafael
Published: August 2021

Los Móviles del compositor cubano Harold Gramatges (Santiago de Cuba, 1918-La Habana, 2008) no han sido profundamente estudiados. Dentro de esta serie de obras, se encuentra el Móvil IV para guitarra, el cual fue escrito en 1980, pero responde a la visión estética de la vanguardia musical de la década de 1960. La presente investigación pretende responder a la pregunta: ¿cuáles fueron las técnicas y recursos composicionales utilizados por Gramatges en su Móvil IV? Para ello, se realiza un análisis general de la obra con auxilio de la partitura, el registro sonoro y algunos gráficos, especialmente diseñados para esta investigación, que muestran los recursos y procedimientos técnicos empleados por el compositor y que facilitaron la valoración holística de los múltiples elementos que conforman el discurso musical. También, se aplican conceptos y definiciones de Pierre Boulez que se adecúan a las obras pertenecientes a las vanguardias históricas.

Este artigo teve como objetivo principal investigar as funções cognitivas associadas às dificuldades em aritmética, focando em: a) analisar a relação entre o desempenho neuropsicológico e o desempenho em aritmética da amostra total de cada ano escolar; e b) investigar o desempenho dos alunos nas funções neuropsicológicas, divididos de acordo com o desempenho em aritmética, para cada ano escolar. Participaram do estudo 167 alunos do 4º e do 6º do Ensino Fundamental, com idades entre 9 e 12 anos. As principais análises realizadas envolveram os escores do Subteste de Aritmética do Teste de Desempenho Escolar (TDE) e da bateria de avaliação neuropsicológica NEUPSILIN-Inf. Foram feitas correlações de Pearson entre a amostra total de cada ano escolar e o Teste t para averiguar diferenças entre os grupos, de cada ano escolar, formados com base no desempenho do TDE. Os resultados sugerem que quanto melhor o desempenho aritmético no TDE, mais altos os escores em memória, cálculos e fluência verbal no NEUPSILIN-Inf. Os alunos do grupo com dificuldades aritméticas apresentaram escores inferiores nos testes que avaliaram, principalmente, funções executivas e memória. Sugere-se um investimento em práticas educacionais que estimulem o desenvolvimento de tais funções cognitivas, com o intuito de prevenir as dificuldades aritméticas.

Published: August 2021

Rivers protection is fundamental for the socioecological systems, and the benthic macroinvertebrates communities can be used to assess the quality of river waters. This study aimed to assess the water quality at Cachoeira do Paraíso waterfall, Peruíbe, SP, based on the benthic macrofauna. Sampling took place at 3 sampling sites, under different levels of anthropic influence. Water physical-chemical and sedimentological parameters were evaluated, as well as macrobenthic organisms. Samplings were done by kick sampling technique. The organisms were identified at the lowest possible taxonomic level and points were attributed to each group according to their respective sensitivity and tolerance to pollutants. Then, a biological index was calculated to indicate the water quality. Ecological indices were calculated and compared using ANOVA. The water physical-chemical parameters showed to be within the legal standards. 13 taxonomic groups of benthic macroinvertebrates were identified, with the Shannon diversity indices indicating similar taxonomic diversity. The score given to each taxa generated biological indices for each sample, ranging from regular to excellent. Diptera (with head) I was the most representative taxon, and sensitive taxonomic groups, were found in all the sampling sites, suggesting a good quality of the water body during the period of study.

Automatic closed-loop scheduling in underground mining using discrete event simulation
Authors: Skawina B. , Astrand M. , Sundqvist F. , Greberg J. , Salama A. , Ekbeck P.
Published: August 2021

Today's mining operations require fast reporting and rapid rescheduling based on updated information. An automatic mine scheduling system could not only quickly reschedule but also propose alternative solutions. To avoid the financial and physical risks associated with testing such a system directly in operation, it could be first evaluated via discrete event simulation models. This would offer a safe environment to evaluate different operating rules and algorithms. In this study, this is achieved by integrating automatic scheduling software with a discrete event simulation model.

Furnace wall tubes from 600 MW subcritical boilers at three coal-fired power stations were sampled and the fireside deposits examined to determine the mechanism of fireside corrosion. This involved an in-depth investigation into the morphology and composition of the fireside deposits and the conditions of the furnace that enable this type of attack. SEM-EDS analysis revealed high concentrations of oxygen, iron, and sulphur, QEMSCAN and XRD analyses identified the presence of Fe3O4, Fe2O3, FeS, and FeS2. Differential thermal analysis showed thermal activities at temperatures of 500-600°C, 900-1100°C, and 1100-1250°C, which are associated, respectively, with FeS2 oxidation to FeS and Fe2O3, at 475-525°C, formation of aluminosilicates at 925-1100°C, and melting of FeS around 1190°C. The absence of sodium and potassium eliminates the contribution of molten alkali sulphates to the corrosion. The consistent coexistence of iron sulphide and iron oxide is indicative of the substoichiometric conditions in the furnace, while the detection of pyrite suggests that the coal is not completely combusted, which points to a poor combustion process. These observations were affirmed by gas analysis at one of the stations, where very high levels of carbon monoxide were measured at the furnace wall (> 14 000 ppm) and furnace exit (> 3500 ppm). The high CO concentrations are indicative of limited combustion caused by limited O2. These reducing conditions promote the formation of FeS-rich deposit, which is the corrosive species responsible for degradation.

INTRODUÇÃO: A distrofia muscular de cinturas do tipo 2B (DMC2B) é uma doença neuromuscular, degenerativa, rara, hereditária, progressiva, com consequentes prejuízos progressivos na capacidade motora e funcional. OBJETIVO: Descrever e analisar os efeitos da fisioterapia aquática sobre a funcionalidade, força muscular, amplitude de movimento e qualidade de vida de uma paciente com diagnóstico DMC2B atendida em projeto de extensão universitária. MÉTODOS: Paciente do sexo feminino, 32 anos, solteira, com diagnóstico genético de Distrofia Muscular de Cinturas do Tipo 2B, nível 3 da escala Vignos (modificada por Garder-Medwin e Walton). O relato de caso apresenta a reabilitação através da Fisioterapia Aquática (hidrocinesioterapia) e seus impactos sobre a força muscular, amplitude de movimento, capacidade funcional e qualidade de vida da paciente (CAAE No. 43505321.0.0000.0018). RESULTADOS: O protocolo de fisioterapia aquática, composto por 12 sessões, 60 min/2x/semana, resultou em melhoras na capacidade funcional global e aumento de 9,52% na avaliação da função motora distal, aumentos de 100% da força de preensão manual e aumento para o limite superior (grau 5) na escala MRC para várias das musculaturas testadas, além de ganho de ADM e melhora expressiva da Qualidade de Vida. CONCLUSÃO: A melhora funcional apresentada pela paciente sugere que a reabilitação funcional fundamentada na fisioterapia aquática, em intensidade leve a moderada, é uma opção terapêutica segura e eficaz para a melhora da força muscular, amplitude de movimento, capacidade funcional e qualidade de vida na DMC2B.

Protocol for nuclei isolation from fresh and frozen tissues for parallel snRNA-Seq and snATAC-Seq on 10x ChromiumTM platform using the same nuclei preparation (UPDATED version) v5
Authors: G Martelotto Luciano
Published: August 2021

This protocol is an adaptation and extension of the 'Frankenstein' protocol – originally developed for nuclei isolation from fresh and frozen tissue for snRNA-Seq – in order to perform snATAC-Seq on the same nuclei prep. It has been successfully applied to fresh, snap/flash and cryopreserved frozen cell lines as well as to tissue derived from solid tumours and other tissues such as pancreas adenocarcinoma (PDAC), breast cancers, pheochromocytomas/paragangliomas, normal paraganglia, brain organoids, PDAC organoids, ovary, fallopian tube, mouse brain and sperm using the Chromium Platform (10x Genomics).

Masoquismo primordial y masoquismo del goce en el surgimiento del sujeto en Lacan
Authors: Escobar Maria Carmen Elisa
Published: August 2021

Para cuestionar la idea freudiana del pasaje de un masoquismo “primario” a uno secundario, y del masoquismo al sadismo, Lacan prefiere utilizar para el masoquismo llamado primario el calificativo de “primordial”. De este modo, la idea freudiana de un resto no expulsado de la pulsión de muerte que permanece en el interior del individuo es modificada por Lacan entendiéndola como el dolor a través del cual el sujeto aprehende el dolor de existir al reconocerse como solo un eslabón de la cadena significante. La incorporación del significante, el goce, es fundamentalmente masoquista. Pero es difícil delimitar la diferencia entre el masoquismo inherente a la génesis del sujeto tal como Lacan la presenta, es decir, como resto de la división subjetiva, y su noción de fantasma masoquista en el neurótico o el masoquismo perverso. La noción plus de goce parece moderar esta superposición, como se mostrará en este escrito.
La imagen inconsciente del cuerpo en la lectura y la escritura de niños
Authors: Colín Cabrera Carmen Araceli
Published: August 2021

En este texto se expone un avance de investigación para destacar la implicación que tiene la imagen inconsciente del cuerpo en la apropiación que hace el niño de la lectura y la escritura.  Algunos psicoanalistas ofrecen sus observaciones e implícitamente dan cuenta de esta relación. Otros la exponen y teorizan explícitamente. La variedad de las dificultades de los niños muestra el trayecto de búsqueda y apropiación de granos de verdad, en cada niño o niña, de lo que ha sido su filiación. Planteo que las observaciones pioneras de Dolto sobre la voz y los recientes trabajos de Porge y su propuesta del Estadio del Eco nos permiten enriquecer esta relación entre letra e imagen del cuerpo y suscitan nuevos problemas y preguntas.
La transferencia literaria en Slow Learner de Thomas Pynchon
Authors: Nils Skare
Published: August 2021

En este artículo se explora el concepto de transferencia del psicoanálisis en el ámbito de la teoría literaria. Formulamos el concepto de transferencia por medio de la enseñanza de Jacques Lacan. Una vez realizado esto, procedemos a la lectura de Slow Learner de Thomas Pynchon teniendo en cuenta la operacionalidad de este fenómeno. Localizamos un síntoma en/de nuestra lectura, problematizamos la transferencia literaria y argumentamos que el inconsciente es aquello que no deja de no escribirse. Discutimos esa formulación y exploramos la escritura como sinthome. Concluimos con la discusión sobre la transferencia negativa y nos abrimos a la importancia política de la literacidad.

La construcción de un dossier sobre Estudios en infancias: formación y educación obedece a la intención de la revista Uni-pluriversidad y de la Maestría de Estudios en Infancias de la Facultad de Educación de la Universidad de Antioquia de presentar a la comunidad académica diversos lugares epistemológicos, conceptuales y metodológicos, desde los cuales académicos han leído y problematizado la vida de los niños y las niñas en situaciones sociales, educativas, económicas y políticas propias. Sus reflexiones se presentan como posibilidad de comprensión de las infancias desde perspectivas múltiples, dando clara evidencia del abordaje transdisciplinar en el que se ha puesto en diálogo la educación y la pedagogía con disciplinas como antropología, historia, sociología, ciencias políticas, derecho, arte, entre otras, toda vez que estas han contribuido a complejizar sus lecturas. El campo de los estudios en infancias constituye entonces una región de intersección entre el campo de la educación, de la pedagogía y las ciencias sociales y humanas. En consecuencia, son muy variados los discursos y los tonos de voz que se expresan cuando se trata de pensar e investigar las infancias, de ahí que las perspectivas de problematización también sean variadas. Por tanto, este dossier es un escenario propicio para el fortalecimiento de la investigación, la generación de conocimiento pertinente y la formación de sujetos interesados en la interpretación, indagación, análisis y construcción de un saber sobre las infancias.
La literatura infantil y la correspondencia: un intercambio entre adultos que acompañan la educación inicial
Authors: Cardona Castrillón Alejandra , Acosta Castrillón Luisa Fernanda
Published: August 2021

Este artículo presenta los resultados de la investigación: La literatura infantil y la correspondencia: un intercambio entre adultos que acompañan la educación inicial, la cual tuvo como objetivo promover la literatura como una experiencia en la educación inicial a partir del género epistolar. El enfoque fue (auto)biográfico narrativo y orientó la escritura de siete cartas sobre la experiencia literaria de las investigadoras. La conversación, la lectura y el intercambio y reconocimiento de saberes fueron medulares para los resultados alcanzados. En el desarrollo de la propuesta participaron 25 maestros de educación Básica Primaria del Área Metropolitana. Los hallazgos representativos se organizaron en tres líneas: la investigación biográfica y narrativa: “un acontecimiento del ser”; la enseñanza de la lectura como un desafío para la escuela; el género epistolar como recurso reflexivo y formativo en la práctica de los maestros. Al final del artículo se comparten algunas conclusiones que dan lugar a nuevas preguntas y caminos de indagación.
