Heterotopias of Higher Education: Technology, Power, and the (Re)Construction of Classroom Space
Authors: Anderson Morgan
Published: May 2024

Abstract In drawing upon traditions of critical geographies and the spatial turn in educational theory, this paper argues there are opportunities for expanding spatial modes of educational analysis to digital topographies. Technology facilitates alternative modes of social
and spatial ordering in higher education in ways that promote freedom, but that are also are uniquely vulnerable to market capture and the neoliberal logics of the university. In particular, Zoom classrooms constitute an example of Foucault’s heterotopia. By exploring each tenet of a
heterotopic space that Foucault outlines in his piece “Of Other Spaces: Utopias and Heterotopias,” this paper argues that bringing Foucault’s theoretical toolkit to bear on these digital environments offers inroads for leveraging critical, normative critiques of the role
of technology in higher education.
Foucault and Hegel: A Theoretical Encounter for Studying Subjectivity and Knowledge in the Contemporary University
Authors: Durán del Fierro Francisco
Published: May 2024

Abstract This paper brings Foucault and Hegel together in a productive way in the context of examining the relationship between subjectivity and knowledge within the contemporary university. While acknowledging the differences between their intellectual projects, I argue
that Foucault’s ethical turn and Hegel’s Phenomenology of Spirit can complement each other in studying subjectivity-constitution. They share a fundamental premise: transforming the subject’s being is needed to access the truth. These modifications of the subject’s being
are carried out by techniques of the self (Foucault) or the path of despair (Hegel). Drawing on the inseparability of epistemology and ethics, I propose an analytical framework for studying the subjectivity-constitution of the subject of knowledge – scholars, academics
or researchers – in the contemporary university. The paper aims to contribute to the study of the relationship between subjectivity and knowledge in the modern university, an area often overlooked in higher education and social studies of science.

INTRODUCTION. The development of post-COVID syndrome is accompanied by an increase in markers of systemic inflammation, a violation of the detoxification function of the liver, caused by both direct viral damage to hepatocytes and an increased iatrogenic load on the hepatobiliary system due to polypharmacy.
AIM. Studying the use of the drug Laennec in the rehabilitation period as a hepatoprotector and immunomodulator in patients with post-COVID syndrome.
MATERIALS AND METHODS. The study included 40 patients with post-COVID syndrome aged 30 to 60 years, with steatosis and steatohepatitis (increased levels of liver transaminases). The clinical effectiveness of Laennec was assessed based on the dynamics of pro-inflammatory biomarkers, liver metabolism indicators, as well as functional tests and psychological questionnaires.
RESULTS. The inclusion of Laennec in the rehabilitation program for patients with post-COVID syndrome leads to a more pronounced improvement in lipid metabolism parameters, correction of liver metabolism parameters, a decrease in the level of pro-inflammatory biomarkers, and an improvement in the quality of life of patients than in the control group.
DISCUSSION. Significantly significant positive dynamics in the severity of complaints of general weakness and sleep disturbance, as well as indicators of memory impairment and impaired concentration in the main group could indicate the achievement of anabolic, neurotrophic and bioenergetic effects of the Laennec drug. A significantly significant decrease in the level of liver transaminases in the main group indicates the hepatoprotective effect of the drug Laennec, due to the amino acids, vitamins and microelements included in the drug, which support the reactions of phases 1 and 2 of liver detoxification. Normalization of elevated pro-inflammatory markers (ferritin, IL-6, CRP) in patients of the main group may indicate the presence of anti-inflammatory and immunoregulatory effects of the Laennec drug.
CONCLUSIONS. A course prescription of the drug Laennec for the purpose of correcting pro-inflammatory markers and hepatoprotection can be recommended for use in complex non-drug rehabilitation to increase its clinical effectiveness, as well as improve subjective indicators of the quality of life of patients with post-COVID syndrome.

Published: May 2024

INTRODUCTION. Chronic kidney disease (CKD) is an important health well-being problem globally, with increasing incidence. That tends to create an “epidemic”. Generalized muscle weakness in hemodialysis patients typically affects the lower limbs and proximal muscles. Patients experience impaired endurance and quality of life. Exercise is prescribed for these individuals to improve their physical health and prevent disease consequences.
AIM. To find out the effect of interval versus continuous intradialytic training on muscle quality index and functional capacity in Hemodialysis patients.
MATERIALS AND METHODS. Sixty men with chronic renal insufficiency grade 5 on hemodialysis aged from 45 to 55 years were divided into two groups using computerized block randomization: Groups (A) and (B) each containing 30 patients. They underwent 8-week program of high intensity interval training (HIIT), moderate intensity continuous training (MICT) intradialytic pedaling exercise plus hemodialysis three times per week. Pre-test and post-test evaluations have been carried out for 6-minute walk test (6MWT) and muscle quality index (MQI) of all patients.
RESULTS. Both groups had a significant positive improvement in MQI and 6MWT with different proportions, patients received high intensity interval intradialytic pedaling exercise had a slightly significant improvement in MQI compared to moderate intensity continuous training group. While, moderate intensity training group had a more significant improvement in 6MWT compared to high intensity training group.
CONCLUSION. Both HIIT and MICT are realistic and good options for individuals with CKD and have parallel profits on functional capability and, skeletal muscle quality and overall quality of life.

Published: May 2024

INTRODUCTION. Severe thermal injury (STI) characterized, among others, by hypoxia and oxidative stress (OS). The possibility of maintaining the antioxidant system through the antioxidants usage is proposed, but their effectiveness and duration are debatable issues. On the other hand, correction of OS at STI is theoretically possible by hyperbaric oxygenation (HBO) sessions, but there is a need to assess the benefit-risk ratio.
AIM. Investigate the effect of antioxidants and hyperbaric oxygenation sessions on the course of oxidative stress at severe thermal injury.
MATERIALS AND METHODS. This study involved conditionally healthy individuals (n = 25), and patients with STI (n = 31), randomized into 3 groups: standard methods (n = 11), supplemented with antioxidants (daily injecting of 250 g vitamin C, 1.494 g “Cernevit” and 10 ml “Addamel N” during 14 days, n = 11) or HBO sessions (50–60 minutes in pressure chambers BLKS-30, BLKS-307/1 in the “low dose” at 1.3 Ata, n = 9). Plasma and erythrocytes were evaluated for free radical oxidation (FPO) and total antioxidant activity, malonic dialdehyde (MDA) concentration, activity of superoxide dismutase (SOD), catalase, and glutathione reductase.
RESULTS AND DISCUSSION. At the antioxidant usage was found SOD activity increase by 11 % (p 0.01) on the second day, a decrease in FROer by 13 % (p = 0.012) on the 9th day, and MDAer by 13 % (p = 0.036) on the 6th day. In the HBO group, there was 9 % increase in SOD activity (p = 0.038) after the first session, an increase in glutathione reductase activity by 15 % (p = 0.028) by the 9th day. Thus, it is possible to pre-limit the period of potentially favorable use of antioxidants and HBO, which contributes to the maximum therapeutic effect. The negative consequences caused by the use of antioxidants or HBO have not been identified in this work.
CONCLUSION. The antioxidant usage at STI contributes to the growth of the antioxidant protection of erythrocytes. The HBO usage leads to an improvement in cellular respiration and antioxidant enzymes activity and does not cause a deepening of OS. The optimal duration of prescribing antioxidants is the first 6–8 days, HBO — 9–11 days from the beginning of therapy.

Stannous oxide (SnO2) thin films have garnered significant attention for their promising applications in various electronic and optoelectronic devices. In this study, we investigate the impact of post-annealing on the structural, optical, and electrical properties of stannous oxide thin films deposited using the chemical bath deposition (CBD) technique. The thin films were prepared on a Borosilicate glass substrate, followed by a controlled annealing process to enhance their performance. Structural analysis was conducted using techniques such as X-ray diffraction (XRD) to examine the cubic crystalline structure and the crystallite size increase induced by post-annealing. The results revealed alterations in grain size from the SEM and the purity of samples confirmed from EDX results. The optical properties of the Stannous oxide thin films were examined using UV-Vis spectroscopy. The optical absorption and bandgap characteristics were analyzed to understand how post-annealing influences the optical behavior of the thin films. Where the optical absorption was 320nm and the bandgap ranges were 3.86eV to 3.83eV. Furthermore, the electrical properties of the thin films were evaluated semiconducting nature, and conductivity increased with rising post-annealing. The findings from this study contribute to the understanding of the role of post-annealing in tailoring the properties of Stannous oxide thin films. The optimization of structural, optical, and electrical characteristics is crucial for their successful integration into electronic and optoelectronic devices.
Success Stories of Junior High School Master Teachers Towards Professional Development: A Phenomenological Inquiry
Authors: F. San Luis Noel
Published: May 2024

Professional development of master teachers involves acknowledging expertise and fostering ongoing development through individualized, self-directed learning. This study explored the success stories of master teachers' professional development, influenced by Malcolm Knowles' 1980 Andragogy Theory. Utilizing phenomenology, the research examines consciousness structures from a first-person perspective. The central structure of an experience was its intentionality, its being directed toward something, as it was an experience of or about some object. Based on the responses of the participants, my analysis revealed three emerging themes under the success stories of junior high school master teachers towards professional development were: harmonious group dynamics, supportive team player and coordinated collaboration. Recognizing group dynamics within professional development for master teachers optimizes collaborative learning experiences, enhancing both student interactions and educators' growth while fostering impactful learning spaces and collaborative skills. The educational insights that were drawn from the experiences on the success stories of master teachers towards professional development. The insights of these teachers were geared towards two themes namely: encouraging support and continual professional development. Future researchers concentrating on master teachers' growth may investigate the enduring impact of new teaching methods and their correlation with improved student learning, as well as explore expanding successful master teacher programs to enhance educators' effectiveness.

Development of a Phishing Detection System Using Support Vector Machine
Authors: Agnes Kikelomo Akinwole , Israel Oludayo Ogundele
Published: May 2024

Phishing represents a significant and escalating threat within the cyber domain, inflicting substantial financial losses on internet users annually. This illicit practice leverages both social engineering tactics and technological means to unlawfully obtain sensitive information from individuals online. Despite numerous studies and publications exploring various methodologies to combat phishing, the number of victims continues to surge due to the inefficiencies of current security measures. The inherently anonymous and unregulated nature of the internet further compounds its susceptibility to phishing attacks. While it's commonly believed that successful phishing endeavours involve the creation of replica messages or websites to deceive users, this notion has not undergone systematic examination to identify potential vulnerabilities. This paper endeavours to fill this gap by conducting a comprehensive evaluation of phishing, synthesizing diverse research perspectives and methodologies. It introduces an innovative classification method utilizing Support Vector Machine (SVM), achieving an impressive accuracy rate of 96.4% in detecting phishing attempts. By implementing this model to distinguish between phishing and legitimate URLs, the proposed solution offers a valuable tool for individuals and organizations to promptly identify and mitigate phishing threats. The findings of this study hold significant implications for bolstering internet security measures and enhancing user awareness in navigating potentially malicious online content.

Published: May 2024

Paris 2024 ambitionne d’établir un nouveau modèle de grand événement sportif international (GESI) durable en s’appuyant sur l’agenda 2020+5. En plaçant les Jeux sous l’angle d’un projet de société ambitieux, les organisateurs suscitent beaucoup d’espérance sur de nombreuses dimensions (touristiques, économiques, sociales), alors que les précédentes olympiades ainsi que le grand nombre d’inconnues liées à la candidature puis à l’organisation pourrait justifier la prudence. Précisément, la littérature académique se caractérise par une approche nuancée des impacts des événements sportifs. En effet, la prégnance actuelle de la notion d’héritage ne doit pas occulter des décennies de recherche scientifique sur la complexité de chacune des dimensions censées la constituer. Nous proposons ici une revue de littérature de ces travaux qui portent sur la mesure, l’analyse ou l’évaluation des impacts économiques, sociaux, touristiques et environnementaux. Ils se caractérisent par une forme de complexité et sont grevés d’effets contre-intuitifs qui doivent être appréhendés pour saisir le potentiel rôle structurant de l’événement sur son territoire hôte. Cette contribution ambitionne de donner des clefs de compréhension aux chercheurs ou aux étudiants qui s’intéressent à ces questions de l’impact des événements sportifs car malgré les difficultés méthodologiques qui jalonnent cette thématique, les GESI restent de précieux révélateurs des dynamiques démocratiques, sociétales et politiques à l’œuvre dans nos sociétés.
The 4Rs Framework: Creating A Synergy to Support the Implementation of English Education for Sustainable Development in Rwanda
Authors: Chidakwa Nowell
Published: May 2024

Rwanda started teaching English to support sustainable development and deliver the five key pillars that will help Rwandans transition from their existing way of life to the society they all desire and are happy to be a part of. As a follow-up to the Sustainable Development Goals and the Berlin Declaration on Education for Sustainable Development, the government ensured the standardisation and teaching of English. In order to assist the implementation of English teaching nationally, the theoretical paper explains how the 4Rs Framework—relationship-building, recognition, responsibilities, and reciprocity—combine to generate synergy among many stakeholders and cross-sectoral collaboration. The study presents literature on Rwanda's Vision 2050, education for sustainable development, and teaching using English as a medium of communication. It is founded on a critical literature review. The article discusses options for national transformation while emphasising the importance of locally rooted collaboration. The 4Rs technique is intended to foster discussion among important players about the issues and problems facing the area of education in emergencies rather than serving as a rigid theoretical framework. The study shows the connections between and tensions among the various "Rs," as well as the efficiency of the 4R dimensions in encouraging the teaching of English. The study considered ways to get beyond the approach's drawbacks and difficulties to support sustainable schooling in Rwanda. This framework encourages the creation of a synergistic educational ecosystem that equips students with the information, skills, and attitudes required to actively participate in Rwanda's path to sustainable development.

Este capítulo se deriva de la investigación metodologías educativas preferidas en los procesos de aprendizaje con estudiantes de licenciatura en educación infantil durante el año 2019 en la ciudad de Medellín, Colombia. Un tema con actualidad y relevancia pues implica la didáctica del docente articulado a las maneras de aprender de las estudiantes cuyo objetivo es analizar las metodologías educativas preferidas por las estudiantes de un colectivo estudiantil en sus procesos de aprendizaje. La investigación, se realiza bajo el paradigma positivista con enfoque cuantitativo y alcance descriptivo no experimental, la técnica para la recolección de la información es la encuesta y aplicación de modelos desagregados tipo Logit Multinomial (MNL) y la técnica de preferencias declaradas. Los resultados muestran como las estudiantes hasta los 25 años optan por la metodología de aprendizaje cooperativo que favorece el trabajo en equipo, y las estudiantes mayores de 26 años, prefieren la clase magistral y el aula invertida. Se concluye que la elección de la metodología en el primer grupo de edad, tiene que ver con, las características propias de la edad y disponibilidad de tiempo, mientras en el segundo grupo, está sujeta a aspectos sociodemográficos como ocupación, estado civil, lugar de residencia y tipo de familia, aspectos que determinan la disposición para el trabajo dentro y fuera de clase. Adicionalmente, de manera general las estudiantes consideran que, independientemente de la metodología de preferencia, es fundamental en su implementación el papel del docente en el favorecimiento del aprendizaje significativo, la articulación de la teoría con la práctica para alcanzar mejores comprensiones y posibilitar el desarrollo de habilidades personales y profesionales para su desempeño futuro.

La alfabetización digital es ahora una habilidad necesaria para contribuir a la sociedad en la era digital moderna, pero los adultos mayores son uno de los grupos demográficos que con frecuencia quedan rezagados en esta área, el objetivo de esta investigación es analizar de manera integral el impacto de un curso de alfabetización digital diseñado específicamente para adultos mayores. La metodología cualitativa con enfoque descriptivo adoptada para esta investigación implica la recopilación y análisis de datos no numéricos para comprender plenamente las necesidades y dificultades que enfrentan los adultos mayores en relación con la alfabetización digital, para obtener datos cualitativos sobre las experiencias y puntos de vista de los adultos mayores, se realizaron grupos focales y análisis documental, lo que permitirá el desarrollo de un curso en línea práctico y eficaz adaptado a sus necesidades. Este curso tiene como finalidad cerrar la brecha digital que experimentan los adultos mayores, capacitándolos para participar activamente en la sociedad. Además, esta investigación se esfuerza por proporcionar información y recomendaciones valiosas para la implementación exitosa de programas de alfabetización digital en instituciones educativas que atienden a adultos mayores. Se han logrado resultados importantes mediante la creación y ejecución de un programa de alfabetización diseñado específicamente para personas mayores. Este programa no solo se enfoca en enseñar habilidades fundamentales de lectura y escritura, sino que también abarca un alcance más amplio que incluye el bienestar emocional y la participación activa dentro de la comunidad. El estudio enfatiza que la educación para los adultos mayores va más allá del dominio académico, donde el bienestar general y la integración social son elementos cruciales que deben tenerse en cuenta al desarrollar iniciativas de alfabetización.

La investigación tuvo como propósito analizar la gestión de la contratación pública como aporte al desarrollo económico y social de los municipios de cuarta categoría del departamento del Cesar, a fin de determinar que tanto influyó en el desempeño municipal y la satisfacción de necesidades de los habitantes. La metodología utilizada para este estudio fue de enfoque cualitativo, mediante el tipo estudio de caso, pues conforme a la información recabada se pudo visualizar que solo existe un municipio de cuarta categoría en el departamento del Cesar. Los resultados de esta investigación arrojaron 229 procesos, de los cuales el 74% fueron por la modalidad de contratación directa, demostrando una exuberancia de procesos sin previa selección de proponentes; así mismo se notó una desarticulación del gasto público con las necesidades de la población, lo que evidencia una falta de planeación en los procesos de contratación: Por último, se presentan alternativas de solución para la eficiencia de la contratación pública en los municipios de 4 categoría, considerando las nuevas tendencias de la administración, la sinergia entre involucrados, herramientas de desarrollo sociales y priorización de sectores económicos y sociales; todo ello consolidad en la utilización de los principios de la administración.

El presente trabajo tuvo como propósito reconocer y caracterizar los géneros académicos en los programas de licenciatura de la Universidad Popular del Cesar, de tal forma que se aporte en la reflexión del papel de la lectura y escritura en la formación docente y la construcción de propuestas didácticas pertinentes para cada área disciplinar. Para lograr el objetivo, se aplicó una metodología mixta, que consideró la realización de entrevistas, observaciones de clase, grupos de discusión y análisis de textos a través de una matriz que tuvo en cuenta seis variables: macropropósito comunicativo, macropropósito pedagógico, relación entre los participantes, modos de organización del discurso, modalidad y contexto de circulación ideal. Los participantes fueron 7 docentes y 22 estudiantes de 5 Licenciaturas de cuatro campos disciplinares: lenguaje, matemáticas, ciencias naturales y educación física. Se lograron identificar 14 géneros de lectura y 13 géneros de escritura a partir de un corpus de 115 textos, destacándose que: a) el artículo científico como el género más leído, b) el organizador gráfico, los informes de lectura y el plan de clase como los géneros de escritura de mayor presencia, c) los géneros de lectura son en su mayoría monomodales y con el macropropósito pedagógico enfocado en instruir, en contraste con los de escritura, predominantemente multimodales y con el macropropósito pedagógico de constatar. Se encontró que muchas veces los estudiantes no logran capturar las intenciones que asignan los docentes a las tareas de lectura o escritura; asunto que conviene revisar de cara al peso epistémico y pedagógico que tienen estas prácticas en la formación docente
