Published: January 2023

The study of nanofluid flow over a rotating disk has significant importance because of its enormous range of implementations, including cancer treatments, chemotherapy, nanomedicines, fermentation sciences, selective drug delivery, food sciences, biosensors, biomedicines, and electronics. Due to these applications of nanofluid, the present problem investigates the magnetohydrodynamic flow of nanofluid with nonlinear thermal radiation and viscous dissipation. In this analysis, the aluminum oxide nanoparticles are mixed with water. Furthermore, the mechanism for inter-particle spacing and radius of aluminum oxide nanoparticles on the dynamics of the two-dimensional flow of nanofluid are investigated. The present problem is modeled in the form of partial differential equations (PDEs), and these PDEs are converted into ordinary differential equations with the help of suitable similarity transformations. The analytical solution to the current modeled problem has been obtained by using the homotopy analysis technique. The main purpose of the present research work is to analyze the behavior of the velocity and temperature of the nanofluid for small and large radius of the aluminum oxide nanoparticles and inter-particle spacing. Also, the role of heat transport is computed for linear and nonlinear thermal radiation cases. The major findings and principal results of this investigation are concluded that the primary velocity of nanoliquid is augmented due to the intensification in suction parameter for both the small and larger radius of aluminum oxide nanoparticles. Furthermore, it is perceived that the heat rate transfer is larger when the Eckert number and nanoparticle volume fraction are higher for both nonlinear and linear thermal radiation cases.
Beliefs on translation speed among students. A case study
Authors: Jamoussi Rafik , Al Zahran Aladdin , Kadhim Kais A.
Published: January 2023

Novice translation graduates are often found to be slow translators. The fact that this deficiency is usually rectified through professional experience implies that initial performance issues are the outcome of a complex interplay of factors, which do not involve intrinsic abilities. Based on insights from cognitively oriented research on students’ beliefs about language learning and the impact these beliefs have on students’ performance, the present study posits that the beliefs students have towards the question of translation speed represent one of the factors that fashion their productivity. Targeting graduates from the English Language and Translation programme at a private university in an Arab Gulf State, a mixed method approach, including a survey and a semi-structured interview, was adopted to explore the beliefs students have towards the question of speed and to identify the sources of these beliefs in their training programme. Analysis reveals that productivity awareness among the investigated population is almost non-existent and points at the predominantly product-oriented approach that characterises their learning experience as the main source of this condition. This article argues that improving students’ awareness of productivity requirements is not just a case of integrating timed activities, but calls for the adoption of multi-layered process-oriented training principles and practices at the level of delivery, feedback, and assessment criteria.
Anti-Work Architecture: Domestic Labour, Speculative Design, and Automated Plenty
Authors: Hester Helen
Published: January 2023

This article presents a partial history of visions of technodomesticity in the global north, concentrating on dwellings which seek to problematize, challenge, or reorganize unpaid household labour. It is structured around three case studies, primarily drawn from the United States in the 1950s and 1960s: the single-family suburban dream house, the bachelor pad, and the fully automated future home. While these chosen examples may lend us certain resources for thinking about how best to mitigate the challenges of reproductive labour via living arrangements, they also possess a number of clear drawbacks or limitations. The article will argue that contesting these imaginaries (as much as learning from them) is likely to prove necessary in unpicking the connections between an inequitable distribution of unpaid intrafamilial domestic labour and the house itself as both a concrete site and an ideological formation – necessary, that is to say, in terms of building a meaningfully feminist conception of anti-work architecture.
Analysis on the effects of hypo-attenuated leaflet thickening on the hemodynamics of transcatheter aortic valve prostheses by means of particle image velocimetry
Authors: Oldenburg Jan , Borowski Finja , Kaule Sebastian , Schmitz Klaus-Peter , Öner Alper , Stiehm Michael
Published: January 2023

The minimally invasive therapy for the treatment of aortic valve regurgitation and stenosis, transcatheter aortic valve replacement (TAVR), is an alternative to surgical valve replacement. Promising clinical results led to the consideration of expanding the use of TAVR in younger patients with lower surgical risk. This implies a longer durability of the TAVR. In relation to the durability of the TAVR, thickening of TAVR leaflets, including reduced motion, has been clinically observed. The aim of this study was to analyse the effects of valve leaflet thickening with reduced leaflet kinematics on the hemodynamics. We measured the flow through a TAVR under pulsatile conditions by using phase-resolved particle image velocimetry (PIV). It has been shown that flow conditions alter in a pathological manner in a TAVR replica with thickened leaflets compared with thin leaflets. In detail, shear stress and Reynolds stress increased by up to a factor of two and additionally the washout behaviour was worse for thickened leaflets. This suggests that a thickened valve is at higher risk for platelet activation and aggregation. This could lead to a self-reinforcing process in which the formation of a thickened valve promotes thrombus formation, which in turn promotes further progression of the thickening.
Research on turboprop engine control method based on linear parameter varying model
Authors: He Liqiang , Li Siyuan , Du Jiatong , Zhang Haibo
Published: January 2023

Starting from a component-level nonlinear model of a turboprop engine, the high-pressure turbine speed and power turbine speed output data at six steady-state operating points are linearized and fitted, and a turboprop engine state variable model is established. Based on these state variable models, the Proportional Integral Derivative (PID) control method, the augmented Linear Quadratic Regulator (LQR) control method and the Linear Quadratic Gaussian/Loop Transfer Recover (LQG/LTR) control method are used to design the controllers respectively, and the relative converted speed of the high-pressure turbine is selected as the scheduling parameter of the Linear Parameter Varying (LPV) model, and the controller is called to control the turboprop engine’s non-linear speed. Linear model for large envelope control. Finally, the control effects of the above three control methods are compared and analyzed, and their advantages and disadvantages are compared. The simulation results show that the LPV controller designed based on the LQG/LTR method is more effective than the controllers designed by the other two control methods on the nonlinear turboprop model.

Bosquejo de una historia conceptual de las dos primeras épocas de Regeneración (1900-1905). Un acercamiento a la configuración discursiva antiporfirista del siglo XX en México
Authors: Tepos Navarro Hans Cristian Jaid
Published: January 2023

El semanario de Regeneración ha sido considerado por la historiografía como uno de los principales periódicos de oposición que se publicó durante el porfiriato y, más tarde, en la época de la Revolución Mexicana. En sus páginas es posible encontrar dos corrientes políticas a partir de las cuales se formularon sus principales propuestas: el liberalismo antiporfirista y el anarquismo. Sin embargo, consideramos que su postura antiporfirista ha sido poco explorada y, en ocasiones, relegada a un segundo término -comparada con la anarquista-, lo cual ha limitado su comprensión. El propósito de este artículo es, pues, analizar los contenidos semánticos de los conceptos de Estado, libertad y revolución en las primeras dos épocas del semanario, cuyo examen pensamos permitiría matizar los principales elementos que configuraron su discurso político y reconocer sus alcances políticos para ahondar en las críticas formuladas al gobierno de Porfirio Díaz.

POST-BREXIT: FROM INTEGRATION TO CONFRONTATION
Authors:   Institute of Europe, Russian Academy of Sciences, Babynina Lyudmila
Published: January 2023

The article is devoted to the analysis of current relations between the European Union and the United Kingdom, as well as the possibilities for creating a closer partnership. The article considers three areas of mutual interest for the parties – the preservation of the EU regulatory framework in British law, cooperation in Northern Ireland and the development of trade relations. The author comes to the conclusion that the presence of objective prerequisites for the creation of a new integration format does not automatically lead to its implementation. On the contrary, the ruling elite of Britain is aimed at maximum distance from the EU rules, which is expressed, in particular, in the consistent change of the Union legislation preserved in national law and the desire to abolish specific regulation in Northern Ireland. Special attention is paid to the situation around the implementation of the Northern Ireland Protocol and the British bill, which cancels its effect unilaterally. The author concludes that instead of a unique integration format and the prosperity of the region, the parties may, in extreme cases, come to a state of trade war and exacerbate contradictions within Northern Ireland.

Published: January 2023

Aim: Intracoronary murmur results from turbulent flow due to coronary artery narrowing. This study evaluated the diagnostic performance of a method for acoustic analysis of turbulent murmur caused by coronary artery stenosis in coronary artery disease (CAD) in Chinese populations.

Method: Patients admitted to the cardiovascular department of the Sixth Medical Center of the Chinese People’s Liberation Army General Hospital between September 2021 and June 2022 for elective coronary angiography were prospectively enrolled. A digital electronic stethoscope was used to record heart sounds before angiography. Quantitative coronary angiography (QCA) served as the “gold standard” for CAD diagnosis to evaluate the diagnostic performance of the acoustic analysis method for CAD.

Results: A total of 452 patients had complete QCA and heart sound data. The final interpretation results of the acoustic analysis method indicated 310 disease cases and 142 normal results. Increasing the cut-off values of coronary artery diameter stenosis from 30% to 50%, 70%, and 90% increased the sensitivity and NPV of the acoustic analysis method; the sensitivity was 75.6%, 81.9%, 83.3%, and 85.7%, respectively; the NPV was 33.1%, 57.0%, 69.7%, and 88.0%, respectively; the specificity and PPV decreased (specificity of 75.8%, 70.4%, 51.0%, and 37.5%, respectively; PPV of 95.2%, 89.0%, 69.4%, and 32.9%, respectively); and the AUC values were 0.757, 0.762, 0.672, and 0.616, respectively. The sensitivity of the acoustic analysis method for one-vessel disease was 86.6% when the cut-off value was 50%. The sensitivity for identifying left anterior descending coronary artery lesions was best, at 90.7%. The sensitivity for identifying isolated coronary artery branch lesions was 66.7%, whereas the sensitivity for identifying three-vessel disease in multi-vessel coronary artery lesions was better, at 82.9%.

Conclusion: Acoustic analysis of turbulent murmur caused by coronary artery stenosis for diagnosis of CAD may have favorable performance in the Chinese population. This method has good performance in CAD diagnosis with a cut-off coronary artery diameter for stenosis of 50%.
Blunted Expected Reward Value Signals in Binge Alcohol Drinkers
Authors: Tolomeo Serenella , Baldacchino Alex , Steele J. Douglas
Published: January 2023

Alcohol-related morbidities and mortality are highly prevalent, increasing the burden to societies and health systems with 3 million deaths globally each year in young adults directly attributable to alcohol. Cue-induced alcohol craving has been formulated as a type of aberrant associative learning, modeled using temporal difference theory with an expected reward value (ERV) linked to craving. Clinically, although harmful use of alcohol is associated with increased time spent obtaining and using alcohol, it is also associated with self-neglect. The latter implies that the motivational aspects of nonalcohol stimuli are blunted. Using an instrumental learning task with non-alcohol-related stimuli, here, we tested hypotheses that the encoding of cue signals (ERV) predicting reward delivery would be blunted in binge alcohol drinkers in both sexes. We also predicted that for the binge drinking group alone, ratings of problematic alcohol use would correlate with abnormal ERV signals consistent with between groups (i.e., binge drinkers vs controls) abnormalities. Our results support our hypotheses with the ERV (nonalcohol cue) signal blunted in binge drinkers and with the magnitude of the abnormality correlating with ratings of problematic alcohol use. This implies that consistent with hypotheses, the motivational aspects of non-alcohol-related stimuli are blunted in binge drinkers. A better understanding of the mechanisms of harmful alcohol use will, in time, facilitate the development of more effective interventions, which should aim to decrease the motivational value of alcohol and increase the motivational value of non-alcohol-related stimuli.

SIGNIFICANCE STATEMENTAllostasis theory predicts specific abnormalities in brain function and subjective experiences that occur when people develop drug problems including addiction. Cue-induced alcohol craving has been formulated as a type of aberrant associative learning, modeled using temporal difference theory with ERV linked to craving. Here, we used an instrumental learning task with non-alcohol-associated stimuli to test hypotheses that the encoding of nonalcohol cue signals (ERV) and reward prediction error signals showed blunting in binge alcohol drinkers. We conclude that fMRI can be used to noninvasively test allostasis and associative learning theory predictions in binge drinkers.
INVESTIGATION OF REGULAR AND HYPOALLERGENIC INFANT MILK FORMULAS BY ATR-FTIR SPECTROSCOPY COMBINED WITH MULTIVARIATE ANALYSIS METHODS
Authors: YONAR Dilek , HAMAN BAYARI Sevgi
Published: January 2023

Infant formulas contain nutrients and bioactive ingredients designed to meet the nutrition requirements of infants. The majority of infant formulas are cow's milk (CM) based regular ones. Since CM is one of the most important allergen source, there are specialized formulas such as partially and extensively hydrolyzed, aminoacid‐based for CM‐allergic infants. In the current study, attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) in combination with multivariate analysis was used to identify the molecular differences between commercially available hypoallergenic (HF) and regular formulas (RF) in Turkey. Higher saturated fatty acid (FA) content and qualitatively longer acyl chained FAs were observed in hypoallergenic formulations. The results of hierarchical cluster analysis (HCA) and principal component analysis (PCA) showed that there were differences between the infrared spectra of the two groups. The HF and RF samples were clearly separated from each other in 1200-800 cm-1 spectral region with 83% variation and 100% accuracy.
Women’s Empowerment and Fight against Violence in Latin America
Authors: Sanín Juliana Restrepo
Published: January 2023

Rates of gender-based violence in Latin America are high, but so is the number of women in national parliaments. This article analyzes that apparent paradox, paying attention to feminist and women’s rights mobilization in the region, the role of women in politics, and the development of legislation to address violence against women. Despite a comprehensive reshaping of the legal landscape, there are significant challenges to the implementation of these laws, including violence against women in politics. But feminist transnational activism continues to call for action.
How Sanctions Led to Authoritarian Capitalism in Venezuela
Authors: Bull Benedicte , Rosales Antulio
Published: January 2023

After a deterioration of democratic conditions in Venezuela, in 2017 the United States intensified its sanctions imposed on the regime of Nicolás Maduro. The sanctions failed to topple the regime, but they accelerated the transformation of the Venezuelan economy. To counter the sanctions, Maduro carried out substantive economic policy changes, resulting in the emergence of a neo-patrimonial and authoritarian form of capitalism. In this new model, private ownership is the rule, and economic agents operate for profit. Yet there is frequent state intervention that denies individuals’ fundamental political and economic rights, and the purpose of laws and regulations is ensuring regime survival.

Comparative evaluation of canal cleanliness at apical third using Self-Adjusting File and Wave One File with different irrigants: an in vitro scanning electron microscopic study
Authors: Bakthavatchalam Balakrishnan , Ranjani Muthukrishnan Sudharshana , Amudhalakshmi Krishnan , Dhanalakshmi Subramanian
Published: January 2023

Aim. To evaluate the cleaning ability of two single-file rotary systems- Self-Adjusting File (SAF) and Wave one (WO) systems in removing the smear layer using sodium hypochlorite (NaOCl) + ethylene diamine tetraacetic acid (EDTA) and NaOCl + Qmix as irrigants at apical one-third of the root canal.

Methods. Forty extracted human mandibular premolars were selected and working length was determined. The canal was manually instrumented up to a number 25 size K-file. The roots were divided into the following groups with 10 samples each – Group 1 using SAF: Group 1a- 3% NaOCl + 17% EDTA, Group 1b- 3% NaOCl + Qmix. Group2 using WO: Group 2a- 3% NaOCl + 17% EDTA, Group 2b- 3% NaOCl + Qmix. In the SAF group, the irrigation was performed continuously using the special irrigation apparatus. In the WO group, syringe irrigation was done followed by final irrigant activation using passive ultrasonic irrigation (PUI). The roots were sectioned longitudinally and subjected to scanning electron microscopic (SEM) examination. The amount of smear layer was evaluated using a five score index at the apical third level. Statistical analysis was performed using the Chi-square test.

Results. Group 1 (SAF) showed better canal cleanliness at apical third compared to Group 2 (WO) with both irrigant combinations and the results were statistically significant (p<0.05). 3% NaOCl + Qmix was equally as effective as 3% NaOCl + 17% EDTA in removing the smear layer with no significant difference between them.

Conclusion. Within the limitation of this study, SAF in combination with 3% NaOCl + Qmix or 3% NaOCl + 17% EDTA should be used for removing smear layer in critical areas of the root canal.
Recurrent Takotsubo syndrome: case report and literature review
Authors: Velasco-Malagón Sergio Alexander , Mora-Pabón Guillermo
Published: January 2023

Abstract
Introduction: Takotsubo syndrome is a cardiomyopathy that can lead to severe myocardial involvement. It is characterized by the presence of signs and symptoms suggestive of ventricular dysfunction associated with an adrenergic discharge during a stressful event. This case report presents a literature review, as well as a comparison with other similar cases.
Case presentation. A 56-year-old female with a previous episode of Takotsubo was admitted to the emergency department due to symptoms of acute coronary syndrome and a history of Takotsubo syndrome. Her electrocardiogram showed T-wave inversion in leads V1-V4 and a raise in troponins. Percutaneous coronary angiography revealed no coronary lesions, and an echocardiogram revealed segmental alterations compatible with Takotsubo syndrome, requiring medical therapy with beta-blockers and angiotensin-converting enzyme (ACE) inhibitors, with subsequent improvement in ventricular function.
Conclusions. Recurrence in Takotsubo cardiomyopathy is a rare complication that should be suspected. The risk factors associated with recurrence are not known. Although therapy with ACE inhibitors and beta-blockers seems to have an impact on the recovery of ventricular function in patients with this condition, further studies are necessary to establish the best pharmacological treatment.
Pelvic retroperitoneal echinococcal cyst. A case report
Authors: Ziede-Rojas Edmundo , Ramírez-González Eduardo , Jans-Baez Jaime
Published: January 2023

Introduction: Echinococcosis or hydatidosis is a parasitic zoonosis endemic in Chile that poses an important public health concern. It mainly affects the liver and lungs; however, it may involve diverse areas, with the isolated pelvic location being exceptional and difficult to manage.
Case presentation. A 41-year-old female consulted the emergency department of a hospital in Chile due to lumbosacral pain and was diagnosed with hydatidosis. The patient received surgical treatment and medication, but the disease recurred twice: the first time, a year after the first intervention, and the second time, two months after the second.  Therefore, she required a multidisciplinary approach that included long-term antibiotic therapy and a radical approach to the lesion, achieving an adequate control of the disease.
Conclusion: Pelvic echinococcosis is difficult to diagnose due to its low frequency. This disease should be considered in the event of any cystic lesion in endemic areas. A multidisciplinary management reduces possible complications and recurrence.
The performance evaluation of PPK and PPP-based Loosely Coupled integration in wooded and urban areas
Authors: Gurturk Mert , Ilci Veli
Published: January 2023

In this study, the authors conducted a series of test measurements in wooded and urban areas and analyzed the results for three main objectives. The first objective is to compare the execution of the Loosely Coupled (LC) and satellite-based solutions in terms of accuracy. Compared to satellite-based solutions, the findings confirmed that the LC-based solutions enhanced accuracy by 1 cm in position and 6-7 cm in height components in the wooded area. In the urban area, LC-based solutions improved the position and height accuracies up to 6 cm and 44 cm, respectively. Also, LC-based solutions bridged the gaps and created a seamless solution in which the gaps reach almost 30% in the urban area trajectory. Secondly, the authors investigated the performance of the GPS-based and GNSS-based solutions. In the wooded area, the GNSS-based solution delivered 2 cm better accuracy in both position and height components than the GPS-based solution. In the urban area, the GNSS-based solution improved the accuracies up to 8 and 36 cm in position and height components, respectively. Also, the solution availability of the GNSS-based process is 10% better than the GPS-based solution. The third objective of this study is to test the performance of the PPP and PPK-based solutions in the two test areas. PPK-based solutions outperformed only 2 cm in position and height components compared to the PPP-based in the wooded area; however, in the urban area, the PPK-based solution improved the accuracies 4-5 dm and 1.1-1.5 meter level in position and height components, respectively. These results indicate that the PPP-based solutions offer a similar level of accuracy to the PPK-based solutions in the wooded area where the satellite visibility is high throughout the trajectory. However, the PPK-based solution provided better positioning accuracies in the urban environment with limited satellite visibility.
You Got to Tell: Private Spaces and Public Narrators in Grace Paley’s Stories
Authors: Ortega Martín Diana
Published: January 2023

The American storyteller Grace Paley (December 11, 1922-August 22, 2007) has been known for her political activism and her ability to construct powerful voices which recollected female, migrant, and urban collective experiences in post-World War II America. In her stories, Paley emphasizes the act of storytelling as a tool for creating a collective shared experience out of individual characters, making the personal and domestic collective and political. In this paper, I will analyze the role of Paley’s most prominent narrator, Faith Darwin, bridging the gap between the private and public urban spheres in three different and evolutive stories: “A Conversation with My Father” (1972), “The Long-Distance Runner” and “Faith in a Tree” (1974). These stories exemplify how Faith uses different strategies in storytelling with the purpose of achieving personal identity and empowerment through communal identification and the recollection of familiar experiences

Para entender Camões e a poesia lírica ibérica do século XVI é indispensável compreender o espaço moral-retórico que organiza cada poema enquanto ato comunicativo. Uma importante contribuição para essa tarefa reside na observação dos textos não literários que assinalam operadores culturais do período. Este artigo começa discutindo uma preceptiva retórica que pode iluminar algumas questões de interesse para o discurso poético, especialmente seu propósito, para avaliar alguns aspectos argumentativos da poesia de Camões, explorando o horizonte no qual se configura uma persona lírica a partir de um ethos. A reflexão aqui proposta pretende avançar em um capítulo da história literária, bem como levantar alguns problemas teóricos.
Intramedial and Intermedial Adaptations in the Novelizations of Interstellar and Jumper
Authors: Sobreira Ricardo
Published: January 2023

This study aims at discussing how novels such as Greg Keyes’s Interstellar (2014), and Steven Gould’s Jumper: Griffin’s Story (2007) verbally construct a “transmedia storytelling” process (Jenkins) between literature and the films they transpose from the screen to the pages, namely Christopher Nolan’s Interstellar (2014) and Doug Liman’s Jumper (2008), respectively. The analysis, thus, centers on how both tie-in books operate diegetic, narratological, and psychological transformations (Baetens) on preexisting cinematic material. The discussion suggests that Keyes’ novel reworks the screenplay in an intramedial adaptation while making creative contributions to the story in narratological and psychological terms. Gould’s novelization, however, uses image as the generator, in an intermedial adaptation, to promote the verbal and psychological “reincarnation” of characters and to expand the diegetic universe. The study provides some grounds to support the contention that novelizations, through their interactive relation with new media, expand the scope and versatility of the novel as a genre.
Manifestaciones de violencia contra las mujeres, Argentina (1880-1910)
Authors: Lobato Mirta Zaida
Published: January 2023

En este artículo se analizan diversas formas de violencias contra las mujeres adultas y niñas, en particular de las clases populares, en una sociedad que se transformaba aceleradamente entre fines del siglo XIX y la primera década del XX. En ese contexto las relaciones de género se reacomodaron de diferente modo frente a los cambios en la sociedad, y los episodios de violencia de varones contra mujeres llegaron a los juzgados y a la prensa. A través del examen de expedientes judiciales de la ciudad y la provincia de Buenos Aires presto atención a los procedimientos policiales y judiciales como andamiajes que muchas veces terminaban en la libertad de los acusados. También analizo publicaciones de circulación masiva que tomaban estos episodios reales y los convertían en foco de interés de un público amplio. A través de relatos sobre manifestaciones de justicia por mano propia reflexiono sobre el modo en que se creaba empatía con las víctimas.

Promoción de competencias científicas en textos escolares de Ciencia y Tecnología del segundo grado de educación secundaria de Perú
Authors: Arana Tuesta Petter Martín , Solís Trujillo Beymar Pedro
Published: January 2023

Actualmente, en educación básica, la enseñanza aprendizaje está pasando de un enfoque basado en contenidos a uno basado en competencias, el cual, dada su complejidad, presenta debilidades en su implementación; esto se ha evidenciado con los resultados poco favorables que arroja PISA. Esto debido a múltiples factores, donde uno de ellos es el uso de textos escolares que aún no se ajustan con este enfoque y que ameritan profundizar en este tipo de estudios. Es así como el objetivo de este artículo es analizar en qué medida las actividades que proponen los textos escolares de Ciencia y Tecnología del segundo grado de educación secundaria de Perú, promueven la adquisición de competencias científicas en las personas estudiantes. Para ello, se ha esgrimido la tipología de capacidades, que consiste en una tabla con 4 categorías con sus respectivas subcategorías. Los hallazgos evidencian que un 36.80 % de actividades están propuestas para promover el desarrollo de capacidades de tipo I, como identificar características, establecer relaciones, comparar y definir. Un 33.40 % el de tipo II, como utilizar el conocimiento en situaciones específicas, donde describen lo que sucede, explican cómo sucede y justifican teóricamente por qué sucede. Un 19.20 % el de tipo III, como observar, buscar información en diferentes fuentes, hipotetizar y plantear sus propias estrategias de trabajo, además de realizar experiencias para la obtención de datos. Un 10.60 % el de tipo IV, como analizar información, plantear conclusiones y argumentar con base científica en pruebas y evidencias. Se concluye mencionando que en los textos escolares motivo de estudio, se promueven prioritariamente capacidades de menor demanda cognitiva como las de tipo I y II, en detrimento de las de tipo III y IV, por lo que hay necesidad de una transformación de las actividades propuestas.
Programa Conectar Igualdad en Argentina desde las voces de sus protagonistas. Un análisis de su estructura de gestión y su trama decisional
Authors: Marchetti Braian , Porta Luis
Published: January 2023

El Programa Conectar Igualdad (PCI) en Argentina representó la política más importante de las últimas décadas en materia de inclusión digital. Para llevar adelante la distribución de más de cinco millones de netbooks, el PCI construyó una estructura de gestión encabezada por un Comité Ejecutivo compuesto por distintos sectores del Estado. El propósito de este trabajo consiste en indagar sobre las características de la estructura de gestión del PCI, identificar las áreas del Estado y sujetos intervinientes dentro de esta y analizar la trama decisional resultante de la interacción entre las áreas y sujetos mencionados. La investigación se define como interpretativa y cualitativa en tanto se nutre de una serie de entrevistas en profundidad realizadas a los sujetos protagonistas de la gestión del PCI. Se caracteriza a la estructura de gestión como intergubernamental y a su trama decisional flexible como única alternativa a las problemáticas y tensiones ocurridas en la articulación de las distintas áreas de gobierno intervinientes. Se considera que para futuras políticas de este estilo es necesario delimitar claramente las tareas a cargo de cada área de gobierno para evitar la dispersión y superposición de los esfuerzos realizados en la multiplicidad de tareas a atender. De la misma manera, diversificar los programas en funcionamiento que abarcan tareas desde la infraestructura tecnológica en una escuela hasta la formación docente o la elaboración del contenido pedagógico de las netbooks, facilitará la concreción de los objetivos propuestos. Si bien no hay un único formato en la definición de las estructuras de gestión de este tipo de programas, al ser una política educativa de inclusión digital parece lo indicado que sea el Ministerio de Educación de la Nación quien coordine los destinos de dicho programa, apoyado en otros organismos que puedan actuar de manera complementaria con las compras y contrataciones.

Las acciones en educación ambiental costeras son escasas. A nivel mundial, muchas de las comunidades aledañas a manglares viven en condiciones de pobreza y Costa Rica no es la excepción, esto debido a la mala gestión y al poco empoderamiento que las comunidades poseen hacia los recursos naturales. El presente artículo tiene como objetivo mostrar las primeras fases de la construcción de un proceso educativo no formal en materia ambiental desarrollado en la comunidad costera de Chacarita, Puntarenas, Costa Rica; a partir de un modelo educativo basado en competencias. El proyecto educativo fue contextualizado, por lo tanto se recabó información referida a este manglar, se realizaron muestreos biológicos de moluscos de interés comercial y mangles durante un año. Se realizaron avistamientos de aves, mamíferos y se recolectó información referida a la pesca en la zona. Finalmente, se aplicó una encuesta con el fin de evaluar conocimientos y disposiciones de la comunidad. Los resultados obtenidos permitieron la construcción de competencias y de materiales educativos, además, mostraron que el poblado de Chacarita tiene anuencia a recibir educación ambiental así como participar de actividades como limpiezas y reforestación.
Malestar docente: la inclusión de una niña de 5 años con microcefalia al aula de educación preescolar

En el sistema educativo mexicano, la Ley General para la Inclusión de las Personas con Discapacidad [LGIPD] establece la integración del alumnado con discapacidad al aula de educación regular sin distinción. Este requerimiento ha generado en el personal docente un incremento de exigencias éticas, personales y profesionales que a la postre pueden ser causantes de malestar, es decir, provocar en el profesorado efectos permanentemente negativos que, además de alterar su estado físico y psicológico, deterioren su desempeño profesional. El objetivo de la investigación consistió en caracterizar los factores asociados al malestar docente en una profesora de preescolar en su labor con una niña de 5 años diagnosticada con microcefalia. El estudio fue cualitativo, transversal y descriptivo dada la modalidad de estudio de caso. Se observó a la docente participante dentro del aula regular, se registró la información en un diario de campo seguido de una entrevista semiestructurada. Para la elaboración de los instrumentos de recolección de datos y la posterior interpretación de los resultados se realizaron unidades de análisis elaboradas en el marco de las formulaciones teóricas de Esteve (2003) y Cordié (2007). De los resultados se destaca que las condiciones laborales que enfrenta la profesora para ejercer su trabajo inclusivo le exigen un mayor esfuerzo, tanto físico como psicológico que, aunado a la falta de recursos materiales, de docentes auxiliares y capacitación en materia de inclusión, provocaron situaciones de constante estrés y dificultad para asumir los nuevos roles que requiere la realidad que enfrenta dentro del aula. En este contexto, estos resultados ofrecen para posteriores estudios, la caracterización de aquellos malestares que sobrelleva el docente como respuesta a las disposiciones de LGIPD del Sistema Educativo mexicano y para las cuales no está habilitado profesional ni personalmente. A modo de recomendación, resulta urgente revisar los mecanismos de implementación de la LGIPD principalmente en educación básica, facultar al profesorado de educación regular en temas de inclusión y en el manejo adecuado de sus emociones.
La enseñanza de habilidades de pensamiento superior en escuelas primarias públicas en México

Las habilidades y competencias del siglo XXI enfatizan el desarrollo de habilidades de pensamiento superior (HPS) (Benjamin, 2008; Dwyer et al. 2014; Ku, 2009; Preus, 2012; Rosefsky-Saavedra y Opfer, 2012). La Organización para la Cooperación y el Desarrollo Económicos [OCDE] (2018) también hace hincapié en la preparación de estudiantado capaz de desempeñarse en el mundo global. De igual manera, la Secretaría de Educación Pública [SEP] (2020) señala que México impulsa el pensamiento crítico y la resolución de problemas como uno de los objetivos primordiales y transversales en los bloques de formación y niveles educativos. Sin embargo, existe una ambigüedad en la conceptualización de habilidades de pensamiento superior (Cuban, 1984; Lewis y Smith, 1993; Newmann, 1987; 1990; Stanley, 1998). Asimismo, existen escasos estudios en México (Díaz-Barriga, 2001) que investiguen la temática, especialmente respecto a la percepción y conceptualización de HPS del estudiantado y profesorado, las técnicas y actividades utilizadas por el profesorado para el desarrollo de HPS dentro y fuera del aula, y los factores que influyen en la implementación de HPS. Este manuscrito reporta los hallazgos obtenidos de una investigación cuyo propósito fue explorar las percepciones del profesorado y las técnicas utilizadas en escuelas primarias para el desarrollo de habilidades de pensamiento superior en escuelas públicas en el sureste de México. A través de un diseño mixto secuencial (Creswell y Plano Clark, 2018), utilizando una encuesta, se analizaron datos numéricos y datos nominales. El análisis cuantitativo consistió en una estadística descriptiva; el análisis cualitativo se realizó de manera inductiva y comparativa, bajo los principios del Método de Comparación Constante (Merriam y Tisdell, 2016). En ambos análisis se empleó el programa MAXQDA Pro, versión 15.0. Los resultados de esta investigación muestran las percepciones docentes respecto a las HPS, así como técnicas para la enseñanza y evaluación de las HPS en el aula.
La escritura de textos académicos en la universidad: Una reflexión desde la experiencia docente en la Universidad Pedagógica Nacional
Authors: Salazar Silva María de Lourdes
Published: January 2023

El objetivo principal de este ensayo es abordar los procesos de enseñanza- aprendizaje de escritura en la universidad desde el enfoque de la literacidad académica crítica (Cassany y Castellà, 2010; Cassany, 2015; y Barton y Hamilton, 2004). Esta cuestión se aborda, en particular, a partir de la experiencia propia como docente con profesoras y profesores de educación básica que estudian en la Universidad Pedagógica Nacional (UPN), en la Licenciatura en Educación Preescolar y la Maestría en Educación Básica. Se plantea que el problema estriba en que, en la institución universitaria, no se fomentan prácticas de escritura porque no se pondera su carácter y potencial epistémico; es decir, no se considera que en los procesos de escritura también se construyen y se transforman los conocimientos. Actualmente, la enseñanza de la escritura en las instituciones educativas no parte de un enfoque que se ocupe de generar una identidad de autoría en sus estudiantes, que les permita posicionarse, desde sus discursos, frente a su realidad, que considere la escritura como un medio para generar conocimiento y también para transformarlo. Si bien la implementación de acciones a título individual, desde las prácticas de las personas docentes, son importantes, lo son más las institucionales; por ejemplo, reestructurar los programas educativos para que desde lo curricular se enfatice en los procesos de literacidad académica crítica. Algunas preguntas que guían el escrito son: ¿cuáles problemas respecto a la literacidad académica enfrentan las profesoras y los profesores de educación básica que estudian licenciatura y posgrado en la Universidad Pedagógica Nacional?, ¿cómo se han afrontado esas dificultades desde la trayectoria profesional como docente de educación superior? y ¿qué sugerencias se pueden formular para mejorar los procesos de escritura del estudiantado universitario?
