Published: December 2024

Background

For years, Mexico has reported the highest global incidence of school bullying, with approximately 19% of students going through some form of hostile peer interactions. Despite numerous interventions, these harmful conducts remain deeply entrenched in educational environments.

Objective

To address this issue, we developed Bernstein, a serious game that promotes assertiveness—an essential protective factor that reduces the negative effects of bullying.

Methods

Bernstein was designed using multiple composite scenarios, a methodology grounded in cognitive behavioral therapy. To evaluate the game’s effectiveness, we conducted an exploratory trial using the Rathus Assertiveness Schedule to assess assertiveness levels before and after the intervention. Participants were high school students who met the inclusion criteria of being open to playing a serious game (with no prior gaming experience required) and having access to a computer with internet connectivity for remote participation. A total of 100 students (65 boys and 35 girls) enrolled in the intervention; however, only 46 participants in the treatment group and 46 in the control group completed the study, resulting in a dropout rate of 8% (8/100). A paired 1-tailed t test was used to compare pre- and postintervention scores within each group, and a one-way ANOVA was conducted to compare the average score improvements between the 2 groups.

Results

The treatment group showed a pretest mean Rathus Assertiveness Schedule score of –2.78 (SD 25.93) and a posttest mean of 1.69 (SD 29.48), with a paired 1-tailed t test yielding a P value of .01. The control group had a pretest mean of 2.07 (SD 25.69) and a posttest mean of –2.39 (SD 32.98), with a paired 1-tailed t test yielding a P value of .04. The one-way ANOVA (between groups) yielded a P value of .006, indicating a statistically significant difference, favoring Bernstein over the alternative protocol. Participant feedback highlighted the game’s engaging narrative and character design, although usability issues, such as navigation challenges, were noted as areas for improvement.

Conclusions

The results suggest that Bernstein is a promising tool for promoting assertiveness in high school students, providing a potential strategy for addressing bullying-related issues. The study underscores the value of integrating Bernstein into educational programs, offering students a safe and interactive environment to develop resilience. As an exploratory trial, this study faced limitations affecting the generalizability of findings, including the remote format’s impact on facilitator guidance and a relatively small sample size. Further trials with larger, more diverse groups are recommended to validate these early results and enhance Bernstein’s scalability as part of a comprehensive antibullying strategy.
Understanding Citizens’ Response to Social Activities on Twitter in US Metropolises During the COVID-19 Recovery Phase Using a Fine-Tuned Large Language Model: Application of AI
Authors: Saito Ryuichi , Tsugawa Sho
Published: December 2024

Background

The COVID-19 pandemic continues to hold an important place in the collective memory as of 2024. As of March 2024, >676 million cases, 6 million deaths, and 13 billion vaccine doses have been reported. It is crucial to evaluate sociopsychological impacts as well as public health indicators such as these to understand the effects of the COVID-19 pandemic.

Objective

This study aimed to explore the sentiments of residents of major US cities toward restrictions on social activities in 2022 during the transitional phase of the COVID-19 pandemic, from the peak of the pandemic to its gradual decline. By illuminating people’s susceptibility to COVID-19, we provide insights into the general sentiment trends during the recovery phase of the pandemic.

Methods

To analyze these trends, we collected posts (N=119,437) on the social media platform Twitter (now X) created by people living in New York City, Los Angeles, and Chicago from December 2021 to December 2022, which were impacted by the COVID-19 pandemic in similar ways. A total of 47,111 unique users authored these posts. In addition, for privacy considerations, any identifiable information, such as author IDs and usernames, was excluded, retaining only the text for analysis. Then, we developed a sentiment estimation model by fine-tuning a large language model on the collected data and used it to analyze how citizens’ sentiments evolved throughout the pandemic.

Results

In the evaluation of models, GPT-3.5 Turbo with fine-tuning outperformed GPT-3.5 Turbo without fine-tuning and Robustly Optimized Bidirectional Encoder Representations from Transformers Pretraining Approach (RoBERTa)–large with fine-tuning, demonstrating significant accuracy (0.80), recall (0.79), precision (0.79), and F1-score (0.79). The findings using GPT-3.5 Turbo with fine-tuning reveal a significant relationship between sentiment levels and actual cases in all 3 cities. Specifically, the correlation coefficient for New York City is 0.89 (95% CI 0.81-0.93), for Los Angeles is 0.39 (95% CI 0.14-0.60), and for Chicago is 0.65 (95% CI 0.47-0.78). Furthermore, feature words analysis showed that COVID-19–related keywords were replaced with non–COVID-19-related keywords in New York City and Los Angeles from January 2022 onward and Chicago from March 2022 onward.

Conclusions

The results show a gradual decline in sentiment and interest in restrictions across all 3 cities as the pandemic approached its conclusion. These results are also ensured by a sentiment estimation model fine-tuned on actual Twitter posts. This study represents the first attempt from a macro perspective to depict sentiment using a classification model created with actual data from the period when COVID-19 was prevalent. This approach can be applied to the spread of other infectious diseases by adjusting search keywords for observational data.

An Examination of the Reasons for the Failure of The Mental Defectives Amendment Bill 1928 in New Zealand
Authors: Li Jun
Published: December 2024

The eugenics movement emerged in various countries from the late 1800s to the 1940s, and the Mental Defectives Amendment Bill 1928 was the high point in the history of the eugenics movement in New Zealand, the first and last time that the highest goal of the eugenics movement in New Zealand was included in the provisions of the bill, the sterilization, but the sterilization provision was ultimately forced to withdraw due to the contradictions of various parties, resulting in the ultimate failure of the Amendment Bill 1928. However, the sterilization provision was eventually withdrawn due to conflicts between different parties, leading to the failure of the Amendment Bill 1928. This paper analyzes the reasons for the failure of the Amendment Bill 1928, in order to get a glimpse of the basic map and direction of New Zealand’s social history at the beginning of the twentieth century.

El presente ensayo tuvo como objetivo profundizar en una serie de aspectos inherentes al modelo de negocio de franquicias, considerando algunas evaluaciones preliminares que son sensatas realizar y no siempre se abordan. Entre otras, la disrupción tecnológica ha recibido un nuevo empuje después de la pandemia y la misma es de particular interés debido a la rapidez con la que avanza, afectando las relaciones de intercambio entre vendedores y compradores, constituyéndose esta realidad en un reto para el modelo de negocios de franquicias ya que las mismas por su naturaleza tienden a ser menos reactivas a mecanismos de innovación por las limitantes que tienen los franquiciados para modificar un modelo de negocio en particular.
The art of killing: “Bluebeard” by Charles Perrault
Authors: Stroev A.
Published: December 2024

Charles Perrault’s fairy tales combine archaic plots and the realities of French life in the Louis XIV era, folklore formulas and literary play, reminiscences from ancient literature (Apuleius’ “Metamorphoses or The Golden Ass”, Virgil’s “Aeneid”). Considered as a single text, together they tell the story of girlhood and family life. It begins with an awareness of female (menarche) and male physiology (“Little Red Riding Hood”, “Sleeping Beauty”). Then the heroine has to avoid incest with her father (“Donkey Skin”, “Griselda”). To marry, she has to enter into a rivalry with her sisters (“Diamonds and Toads”, “Cinderella”, “Riquet with the Tuft”) and magically transform herself to seduce the prince (“Donkey Skin”, “Diamonds and Toads”, “Cinderella”, “Riquet with the Tuft”). Then it is necessary to destroy the ogre-mother-in-law (“Sleeping Beauty”) or the husband-killer (“Bluebeard”). If we consider “Bluebeard” from this perspective, it becomes clear that, as in the detective story, the wife, with the help of her sister, sets up the murder of her wealthy husband, presenting the crime as necessary self-defense. Her brothers in the military killed Bluebeard, leaving him no chance of escape. Like the suspense detective plot popular in the mid-twentieth century (Hitchcock, Boileau-Narcejac), the story is told from the point of view of the victim who engages in a duel with the perpetrator. In the verse fairy tale “The Ridiculous Wishes”, in the poem “The Apology of Women” and in the verse moral of the fairy tale “Bluebeard” Charles Perrault engages in ironic polemics with feminists (“précieuses”) and assures us that women command men. In the fairy tales “Diamonds and Toads” and “Riquet with the Tuft” he enters into competition with the late 17th century fairy tale writers (Marie-Jeanne “L’Héritier de Villandon”, Catherine Bernard) who used the same plot. It is possible that in “Bluebeard” he is taking aim at another storyteller, Marie-Catherine d’Aulnoy, who in her youth was convicted for plotting against her husband.
The seamy side of civilization: Fashion in a meat market setting
Authors: Gusarova K. O.
Published: December 2024

The article considers the wholesale meat market as a persistent background for verbal and visual fashion imagery. This setting is inherently contradictory, as it combines the features of two key sites of industrial modernity, which tend to be seen as unconnected, if not mutually opposed to each other. On the one hand, the meat market, where animal carcasses can be flayed and carved into pieces, bears similarity to the abattoir — a marginal site which in the nineteenth century was removed from Western urban centers for hygienic and moral reasons, yet proved central for shaping modern production technologies and visual regimes. On the other hand, as a place of commerce, the meat market shares some characteristics with a shop window that transforms various materials into commodities and serves as a screen onto which the desires of consumer society are projected. The article focuses on representations of the Parisian central food market, Les Halles, and similar venues situated in the suburbs of Paris and other French cities. The case studies under examination are Emile Zola’s 1873 novel The Belly of Paris; Guy Bourdin’s photographs set in Les Halles and intended for the February 1955 issue of Vogue Paris; and Dora Kallmus 1940–1950s photographic series taken in Parisian abattoirs and meat markets. In all three instances, the meat market becomes both the locus and the object of critical reflection, touching upon such topics as aesthetics and the appeal of commodities, physical vulnerability and mortality, the responsibility of the artist and the audience. While only Bourdin’s photographs feature a literal fashionable display set in a meat market, both Zola and Kallmus draw upon fashion imagery to make a point about the various ways flesh can be commodified.

Fusion of Wiener Filtering and BM3D Denoising for Improved Image Restoration
Authors: Praveen Kumar Lendale  , N.M Nandhitha  , Sravanthi Chutke
Published: December 2024

The objective of image restoration work, or image processes, is to return an observed image Y, that has been corrupted with noise, to its original form. In other words, given an image that consists of noise and blurred content, we aim to find the original image. The non-blind image restoration, in particular, focuses on the recovery of a case of unknown images with application of an assumed known blur. Wiener filter is a very popular image restoration tool. It can be thought of as the optimal sift in the rooted space of the blurred image to produce the least number of artifacts due to wider blur. However, one disadvantage is the need-to-know anticorrelations of the blur, the anti-blurred image and the noise. This paper contains the implementation of such non-blind image restoration where Wiener parametric filtering is used with BM3D. In this stage, the parametric Wiener filter is first used to deconvolve the image in the frequency domain, and then the BM3D technique is employed. The performance of the developed algorithms gives quite interesting and quite optimistic results.
The Role of Physical Activity and Exercise in the Prevention and Treatment of Depression
Authors: ÇAKMAK Selcen
Published: December 2024

Depression is a term that refers to a clinical syndrome or disorder characterised by a feeling of hopelessness or unhappiness. Symptoms include weight loss with loss of pleasure, sleep changes (i.e. insomnia or hypersomnia), psychomotor agitation or regression, fatigue or loss of energy, feelings of worthlessness or excessive guilt, reduced ability to think or concentrate, and recurrent thoughts of death. Basically, treatment consists of pharmacological and psychological interventions. Although these treatments are effective, not all patients achieve the same results. In this case, alternative approaches are needed to prevent and treat depression. Our literature review shows that high levels of physical activity and exercise have protective effects on depression cases.  In combination with other treatment modalities, exercise and physical activity may lead to a more rapid improvement of the clinical picture. In this article, we reviewed the current literature on the use of physical activity and exercise for the prevention and treatment of depression.

Concentração da estrutura fundiária e conflitos por terra em municípios baianos cortados pela Ferrovia de Integração Oeste-Leste (FIOL)
Authors: Tosta Souza Suzane , Diniz dos Santos Jânio Roberto , De Almeida Santos Tiê
Published: December 2024

As grandes obras promovem transformações espaciais e, em geral, encontram-se vinculadas aos interesses do capital e do rentismo fundiário. Esse processo, fomentado pelo Estado, traz também a intensificação das desigualdades espaciais, a exemplo da concentração fundiária e dos conflitos pela terra. É essa realidade que o artigo aborda, destacando sua relação com a construção da Ferrovia de Integração Oeste-Leste (FIOL). Para tanto, ancoramo-nos na coleta e análise de dados da estrutura fundiária fornecidos pelo IBGE/INCRA/Censos Agropecuários e dos conflitos no campo – por meio dos Cadernos Conflitos no Campo, da Comissão Pastoral da Terra. Esta análise, no movimento com a teoria, permitiu apontar tanto o aumento da concentração fundiária, quanto de conflitos no campo em municípios baianos cortados pela FIOL.
A construção da Educação Antirracista em uma perspectiva garantista
Authors: Nunes dos Santos Freitas Karollayne
Published: December 2024

O presente trabalho analisa a construção da educação antirracista, considerando a perspectiva garantista de Luigi Ferrajoli, especificando a discussão no âmbito do direito fundamental à educação em condições de igualdade. Tem o objetivo de examinar o texto legal estabelecido no art. 205 da Constituição Federal e no art. 76-A da Lei n. 10.639/2003, considerando o caráter sociojurídico que reveste o direito à educação. Para o desenvolvimento da pesquisa, foi adotada a abordagem dedutiva, analisando premissas gerais, para a discussão aprofundada da legislação, com base na revisão de literatura. Assim, o método de procedimento utilizado segue a pesquisa bibliográfica e documental, a partir da reunião de textos científicos e legislação pertinente. Nesse contexto, compreende-se que apesar dos avanços jurídico-legais, o caminho para a construção de uma Educação antirracista é calcado por obstáculos, principalmente aqueles de natureza política, dificultando o acesso e a efetividade das políticas educacionais em igualdade para todos. Por fim, ressalta-se a necessidade do debate acadêmico e social sobre a temática e, paulatinamente, a importância de contribuições interdisciplinares para a expansão do conhecimento acerca da imprescindibilidade da construção de uma Educação Básica Antirracista.
Convergência tecnológica e saúde: desafios bioéticos em um contexto de transformação

Essas áreas, ao se integrarem, criam novas possibilidades para a ciência e a tecnologia, moldando o futuro da humanidade. A relação entre progresso científico e riscos éticos, como os dilemas da justiça distributiva e a privacidade, torna-se cada vez mais relevante em um contexto de inovações tecnológicas aceleradas. A CT sugere um cenário em que a saúde, a biotecnologia e a inteligência artificial convergem para transformar o corpo humano e expandir suas capacidades, mas também levantam questões bioéticas importantes, como o acesso justo às tecnologias e a preservação da dignidade humana. Em tempos de crise global, a reflexão sobre essas inovações e seus impactos é fundamental para garantir que os benefícios sejam amplamente compartilhados, preservando o equilíbrio entre o avanço tecnológico e os valores humanos.
Science Literacy and Critical Thinking Skills of Elementary School Students: A Correlation Study
Authors: Ayu Apriliana Nindi , Anggrella Dita Purwinda
Published: December 2024

Scientific literacy includes students' ability to understand scientific concepts, apply that knowledge to solve problems and make decisions based on scientific information. Meanwhile, critical thinking skills involve analysing, evaluating, and synthesising information logically. This study aims to analyse scientific literacy skills, critical thinking skills, and the relationship between the two in elementary school students. The research method used is a quantitative approach with a correlational type. The population in the study involved 68 students of grade V MI Muhammadiyah Trangsan, so a sample of 58 students was obtained using the Slovin formula. The sampling technique used was simple random sampling. Data were collected through essay tests of scientific literacy and critical thinking skills on the water cycle material. The results showed an average value of scientific literacy of 62.71, which is in the moderate category; an average value of critical thinking skills of 71.93, which is in the moderate category; and a correlation coefficient value of 0.617, which indicates a fairly strong positive relationship. This result means that the higher the students' scientific literacy skills, the better their critical thinking skills. A simple linear regression test shows R2 = 0.381, meaning that scientific literacy factors influence 33.8% of critical thinking skills, while other factors influence the remaining 66.2%. This finding indicates the importance of strengthening scientific literacy in learning to improve students' critical thinking skills.
Lesiones intestinales atípicas en una paciente con neurofibromatosis tipo 1: reporte de caso
Authors: Puentes Manosalva Fabian Eduardo , Londoño López Rubén Darío , Sánchez Gil Andrés , Arango Molano Lazaro Antonio
Published: December 2024

La neurofibromatosis tipo 1 (NF1) es un trastorno neurocutáneo que puede manifestarse en forma de múltiples tumores o lesiones plexiformes en el tracto gastrointestinal y a nivel extraintestinal. El compromiso gastrointestinal representa el 10%-25% de todos los pacientes. Los neurofibromas son el tipo más común de lesiones que se localizan principalmente en el intestino delgado. Cuando se presentan múltiples tumores en el intestino delgado, comúnmente son tumores del estroma gastrointestinal (GIST). Se presenta el caso clínico de una mujer de 55 años de edad con antecedente de NF1, con neurofibromas y manchas ¨café con leche¨ en todo su cuerpo. Fue atendida de forma ambulatoria en la unidad de endoscopia de Unión de Cirujanos S. A. S. en Manizales, Colombia, en el Servicio de Gastroenterología Clínico Quirúrgica de la Universidad de Caldas, donde se le realizó una ileocolonoscopia, la cual fue indicada por tamizaje positivo de sangre oculta en heces. La paciente negó la presencia de dolor abdominal, hematoquecia, rectorragia o melenas. La ileocolonoscopia evidenció lesiones de aspecto nodular entre 3 y 5 mm en el íleon distal, se realizó una resección endoscópica de una de ellas y se envió a estudio histopatológico.
Adulto con malformación de Abernethy tipo II: reporte de caso
Authors: Guamán Castillo Santiago Nicolás , Guapisaca Vargas Carmen Isabel
Published: December 2024

Antecedentes: las malformaciones de Abernethy son anomalías del desarrollo vascular con hipoplasia o agenesia de la vena porta que presentan una clínica variada debido a sus complicaciones o suelen diagnosticarse incidentalmente mediante exámenes de imagen, en su mayoría en edad pediátrica.
Resumen del caso: se presenta el caso de una paciente de 39 años que acudió a consulta por telangiectasias aracniformes, y los exámenes de sangre revelaron pancitopenia y elevación de transaminasas hepáticas. Por la complejidad del caso, se descartaron enfermedades autoinmunes y trombosis de vena porta mediante un estudio de autoanticuerpos y ultrasonido Doppler. De manera incidental, la tomografía computarizada trifásica de abdomen reportó esplenomegalia, aneurisma de la arteria segmentaria inferior del riñón izquierdo, colaterales esplenorrenales e hipoplasia de la vena porta compatible con malformación de Abernethy tipo II.
Conclusiones: la malformación de Abernethy es infrecuente en el adulto y en este caso fue un hallazgo incidental; aunque los signos dermatológicos aportaron a su detección, aún es poco clara la relación entre el hemangioma con esta patología y su participación como un posible signo físico.

Desafíos en el diagnóstico de gastroparesia: divergencia entre los resultados de las gammagrafías de vaciamiento gástrico para líquidos y sólidos
Authors: Ortega Anaya Klissman , Varela Ramirez Humberto , Montilla Velasquez Maria Del Pilar , Pérez Martínez Javier Alfredo
Published: December 2024

Introducción: para el estudio de gastroparesia en pacientes en los que ya se descartó obstrucción mecánica; la gammagrafía de vaciamiento gástrico con alimentos sólidos es el parámetro de referencia recomendado por las guías clínicas más recientes; aunque también puede evaluarse el vaciamiento gástrico con líquidos, los resultados de ambas fases pueden no ser concordantes.
Objetivo: determinar el grado de concordancia entre los resultados de gammagrafía de vaciamiento gástrico para sólidos y líquidos como estudio de gastroparesia en tres centros de medicina nuclear en Bogotá, Colombia.
Metodología: se revisó a todos los pacientes que fueron sometidos a ambas fases del estudio, y se excluyeron a los menores de 18 años, a pacientes con un resultado acelerado en cualquier fase o con datos incompletos. Se calculó la kappa de Cohen para evaluar el acuerdo entre las pruebas. Se realizó un análisis bivariado entre los resultados de cada prueba y el acuerdo entre las mismas con las variables sociodemográficas y clínicas.
Resultados: 210 pacientes cumplieron los criterios de inclusión, 86 pacientes (41%) tuvieron un resultado retardado en la fase de sólidos y 181 (86%) en la fase de líquidos. El valor de κ fue de 0,082 (intervalo de confianza del 95 % [IC 95%]: 0,005 a 0,16) con resultados estadísticamente significativos (p < 0,05). El principal patrón de divergencia entre los resultados fue el vaciamiento para sólidos normal con líquidos retardado en 102 pacientes (48,6%).
Conclusión: el grado de concordancia entre la gammagrafía de vaciamiento gástrico para líquidos y para sólidos es leve. La fase de sólidos es considerada el parámetro de referencia, por lo que los resultados de la fase de líquidos deben ser usados con precaución en el contexto clínico de cada paciente.

Introducción y objetivos: confirmar la erradicación de Helicobacter pylori es esencial debido al aumento de la resistencia antimicrobiana a diferentes esquemas de tratamiento. El objetivo principal del estudio es determinar el porcentaje de erradicación de H. pylori por medio de la prueba de aliento con carbono 14 (14C).
Materiales y métodos: se realizó un estudio transversal con componente analítico, con recolección retrospectiva de la información mediante la revisión de historias clínicas de pacientes que recibieron tratamiento erradicador para H. pylori y tuvieron una posterior confirmación de la erradicación mediante la prueba de aliento con 14C en el Hospital Universitario Fundación Valle del Lili entre enero de 2019 y junio de 2022.
Resultados: un total de 360 pacientes cumplieron con los criterios de inclusión. El 66,9% de pacientes fueron mujeres, con una mediana de edad de 51 años (rango intercuartílico [RIC]: 39-61), el porcentaje de la prueba de aliento con 14C negativo fue de 84,4% y la mediana de tiempo entre la finalización del tratamiento y la realización de la prueba fue de 8 semanas (RIC: 5-12). Casi todos los pacientes recibieron 14 días de tratamiento.
Conclusiones: en nuestro medio se presenta un porcentaje de erradicación aceptable, inclusive con la terapia triple estándar (la cual sigue siendo la más utilizada). Se requieren estudios de susceptibilidad antimicrobiana para lograr tratamientos basados en la epidemiología local.

Aquatic and terrestrial ecosystems are linked through the reciprocal
exchange of materials and organisms. Aquatic-to-terrestrial subsidies
are relatively low quantity in most terrestrial ecosystems, but they can
provide high contents of limiting resources that increase consumer
fitness and ecosystem production. However, they also may carry
significant contaminant loads, particularly in
anthropogenically-impacted watersheds. Global change processes,
including land use change, climate change, and biodiversity declines,
are altering the quantity and quality of aquatic subsidies, potentially
shifting the balance of costs and benefits of aquatic subsidies for
terrestrial consumers. Many global change processes interact and impact
both the bright and dark sides of aquatic subsidies simultaneously,
highlighting the need for future integrative research that bridges
ecosystem as well as disciplinary boundaries. We identify key research
priorities, including increased quantification of the spatiotemporal
variability in aquatic subsidies across a range of ecosystems, greater
understanding of the landscape-scale extent of aquatic subsidy impact,
and deeper exploration of the relative costs and benefits of aquatic
subsidies for consumers.
Guiding the future: What generation Z expects from tourist guides
Authors: Miljkovic Jovana , Vujicic Miroslav , Kovacic Sanja , Pivac Tatjana , Klicek Tamara
Published: December 2024

Tourist guides have a significant role in the tourism industry, serving as intermediaries facilitating travelers' understanding of their destinations. Historically, guides have been essential in travel experiences, providing insights, narrating the history, and enhancing the overall journey. Hence, the influence of tourist guides on tourist satisfaction and their role in influencing the destination's image have been the subjects of numerous researchers. However, there is not much research regarding Generation Z attitudes about guides. Generation Z is the generation that will travel more in the future. With that in mind, the aim of this paper is to investigate the attitudes and preferences of Generation Z regarding tourist guides, focusing on the essential qualities, behaviors, and types of information that meet their expectations. The survey involved 203 participants. The Statistical Package for the Social Sciences (SPSS) was employed for exploratory factor analysis (EFA), independent t-tests, and one-way ANOVA, whereas R was utilized for confirmatory factor analysis (CFA). The findings highlight the need for tourist guides to possess substantial knowledge and demonstrate practical communication skills, as Generation Z respondents prioritize knowledgeable and well-informed guides, valuing their expertise about the destination. However, the study also found that facilitating active group participation and promoting connections with local communities are less important to this generation.
Carga Mental de trabajo y Satisfacción Laboral en docentes de bachillerato. Estudio comparativo Ecuador-México
Authors:   Universidad Central del Ecuador, Ecuador, Suárez Suárez Frank Steven , Preciado Serrano María de Lourdes ,   Universidad de Guadalajara Mexico
Published: December 2024

Los docentes a nivel bachillerato tienen trabajo dinámico y frecuentemente exigencias a nuevos métodos didácticos, conforme el contexto del que proceden sus estudiantes. El objetivo del presente artículo es evaluar la diferencia de carga mental y satisfacción laboral en docentes de bachillerato en Ecuador y México. Se empleó un método de Estudio observacional y transversal. Se encuestaron a 27 docentes de México y 35 de Ecuador, con la escala CMT-33 para carga mental y el SL/12 para satisfacción laboral, administrados a través de la plataforma Survey Monkey. El análisis de datos se realizó con estadísticos descriptivos y la prueba U de Mann-Whitney para prueba de hipótesis a nivel significativo (p< 0.05). Los resultados del trabajo de investigación sobre la carga mental de trabajo y la satisfacción laboral de los docentes de bachillerato en Ecuador y México revelan que la carga mental es alta en ambos contextos, lo que indica que los docentes enfrentan significativas demandas cognitivas y organizacionales que pueden afectar su rendimiento y bienestar. Además, se observa que la satisfacción laboral varía significativamente entre los docentes de Ecuador y México, siendo más alta en Ecuador. En conclusión, la alta carga mental de trabajo y la insatisfacción laboral son preocupaciones que deben ser abordadas mediante intervenciones específicas para mejorar las condiciones laborales de los docentes.
