Published: August 2024

El estudio de los relatos acerca de la conformación de la identidad docente durante los procesos formativos busca promover una visión crítica que contribuya a la justicia educativa y a la reflexión en torno a la interacción con las comunidades de práctica involucradas. En este marco, la investigación buscó analizar el proceso de construcción identitaria de maestros en formación inicial docente por medio del estudio de las prácticas de legitimación, reconocimiento y participación, y el enfoque de justicia social para la acción. Participaron 12 docentes practicantes que se encontraban en su último año de formación en una universidad de Santiago de Chile. Los resultados evidencian que el profesorado en formación cuenta con nociones de justicia social para la acción relacionadas con la transformación de los espacios socioeducativos. Sin embargo, se constata que existen limitaciones contextuales referidas a su participación y autonomía, lo cual repercute en la agencia docente y en la visión del ser profesor. En conclusión, cobra relevancia la revisión de las condiciones y sentidos de la formación práctica en los programas de Pedagogía, pues ambos se vinculan con el proceso de construcción identitaria del profesorado de y para la justicia social.

Authors: Robles Mendoza Alba Luz , Forero Castillo Nancy Andrea , González Romero Raúl , Jasso Valenzuela Saúl
Published: August 2024

Los estudios de género han marcado las pautas para describir la violencia hacia las mujeres desde roles tradicionales de la masculinidad hegemónica, siendo las representaciones sociales de lo masculino el eje antecesor de la construcción del hombre ante este tipo de violencia. Este estudio de corte cualitativo tiene como objetivo describir, desde las representaciones sociales de la masculinidad, la conceptualización de la violencia hacia las mujeres en varones universitarios de la Ciudad de México, mediante el método biográfico-narrativo. Se recolectaron narrativas organizadas en dos categorías, la vivencia de la masculinidad en la adolescencia y en la actualidad, con cuatro subcategorías cada una. Se encontraron patrones de crianza familiar y de educación universitaria que influyeron en la construcción de la masculinidad frente a la percepción de la violencia hacia las mujeres. El estudio brinda nuevos discursos de ser hombre a partir de las prácticas contemporáneas de las masculinidades.
El trabajo profesional en tensión con la maternidad. Representaciones sobre el trabajo profesional en mujeres que han decidido no ejercer la maternidad
Authors: Fabrina Corsetti Tania
Published: August 2024

Este artículo indaga el lugar que ocupa el trabajo profesional en la vida de mujeres que trabajan en la región del Gran Rosario (Argentina) y que han decidido no ejercer la maternidad. Con una metodología intensiva basada en entrevistas en profundidad me aproximo a la manera en que los cambios en el mundo del trabajo y sus significaciones tensionan y resignifican la relación entre el trabajo profesional y la maternidad. Encuentro que el trabajo profesional constituye una referencia importante en el plano económico, cultural, psicológico y simbólico. No obstante, la consolidación de la flexibilización laboral en una sociedad donde los cuidados siguen recayendo en las mujeres, hace de la simultaneidad de ambos trabajos una tarea irrealizable para buena parte del grupo estudiado; lo que evidencia una intensificación de la tensión entre la reproducción del capital y la reproducción social en el régimen capitalista actual.
Ni Ardidas ni Traumadas: Igualadas. Discursos de Odio Sexista en Contra de Activistas Feministas en Redes Sociales
Authors: Bonilla Sánchez Mariana
Published: August 2024

Las distintas formas de violencia contra las mujeres siguen siendo uno de los desafíos más prominentes en la sociedad. Actualmente, estas agresiones se presentan en espacios y formas que se encuentran lejos de ser comprendidas en su totalidad, siendo un ejemplo las ciberviolencias de género. Este artículo conceptualiza los discursos de odio sexista como una forma de ciberviolencia que busca silenciar a las mujeres, en especial a las activistas, haciendo uso de técnicas de la Ciencia de Datos y el Análisis Crítico del Discurso para identificar las formas en las que operan estos discursos en contra de activistas feministas colombianas en redes sociales, a partir del canal de Youtube de Las Igualadas. Los resultados revelan que los discursos de odio sexista en el canal de Las Igualadas se intensifican en torno a ciertas temáticas y buscan desacreditar a las activistas, fomentando el odio hacia el género femenino en general.
Metabolismo de la vitamina D y su papel en la enfermedad de Alzheimer
Authors: Avila U. Fernanda , Arévalo Nohela B. , SanMartin Carol D
Published: August 2024

Alzheimer disease (AD) is a type of dementia that affects memory, thinking and behavior. Meanwhile, mild cognitive impairment (MCI) is the transitional period between normal aging and dementia, and is the best predictor of future dementia, with an accelerated rate of progression to AD. Amyloid β peptide (Aβ) deposition in AD is due to an imbalance in the production/clearance rate. Vitamin D is a multipurpose secosteroid hormone classically associated with calcium homeostasis, bone formation, and maintenance. However, currently know that vitamin D is a neurosteroid affecting brain development and function; implications for neurological and psychiatric disorders. Many studies have linked low plasma levels of vitamin D with a high prevalence of MCI and AD. Vitamin D acts through its specific nuclear receptor (VDR), which is a transcription factor that binds to the Vitamin D Response Element in the genome. Aβ peptide is transported across the blood brain barrier by LRP1 and P-gp as efflux transporters and RAGE as influx transporter. Numerous evidence indicates that vitamin D modulates the clearance of the Aβ peptide through the regulation of LRP1 and P-gp transporters. This evidence supports the importance of vitamin D food fortification policies recently approved in Chile.

Authors: Khoironi Riadina , Muhsin Muhsin
Published: August 2024

Livelihood is one of the important things in human life, so it is necessary to study it. However, there are differences of opinion about the livelihood of Nushuz's wife. This study examines more deeply the livelihood of the wife of Nushuz by focusing on two problem formulations, namely 1) the livelihood of the wife of Nushuz according to the opinion of Imam Shafi'i and Ibn Hazm, and 2) the legal istinbat used by Imam Shafi'i and Ibn Hazm looking at the issue of livelihood. For nushuz's wife. Using a qualitative literature research method, this research concludes that according to Imam Syafi'i, a nushuz's wife is not entitled to her husband's maintenance until she quits her nushuz. Meanwhile, according to Ibn Hazm, whether the wife of Nushuz or not, she is still entitled to a living from her husband. The legal istinbat used by Imam Shafi'i is qiyas, while Ibn Hazm is the explicit meaning of the Qur'an letter an-Nisa verse 34.
Tangent Cultural Interaction and Postcolonial Hybrid Societal Edifice in Hanief Kureshi’s “My Son The Fanatic”
Authors: Anwar Ansa , Irshad Aasma , Batool Maria , Bin Zubair Hassan
Published: August 2024

This study set out to identify the types of hybridity that arise from postcolonial cultural interaction with colonial formation. The depictions of Parvez and Ali from Hanif Kureshi's short story My Son the Fanatic are hybrids, according to researchers. The Homi K. Bhabha concept of hybridity was used in this study, which followed a post-colonialist strategy. Bhabha's viewpoint (1994), it is the result of a tangential interaction in distinct cultures. In this instance, hybridity is understood to be the result of the dominance of colonial power dynamics which involves not only the merging of cultures but also cultural objects that are situated in social as well as historical space as a result of post-colonialism. Due to its significance in analyzing descriptive text in predetermined literary works, the qualitative descriptive approach was employed in this research. According to the research's findings, there are two different ways that hybridity is represented in this research. First, because of the content creation that was created, mimicry has a character that is ambiguous and contradictory in the context of cultural fidelity. Parvez, an individual in the narrative, serves as a metaphor for mimicry. Second, Ali, his son, represented ambivalence in the story. Ali resisted the construction because he understood how colonialism discriminated against his culture, but he was confused about what identity he should adopt. The short story "My Son the Fanatic" by Hanif Kureishi depicts cultural hybridity through the characters Parvez and Ali, who represent mimicry and ambivalence resulting from the dynamics of colonial and postcolonial power.

Authors: Hall Lisa , Jefferis Alicia , Wanefalea Lynne
Published: August 2024

Feedback is a central part of learning and teaching in all University courses, including for medical students. But can we improve the impact of feedback by using a consistent model across different types of feedback delivery? This project was designed to see if, by using a consistent model of feedback, delivered in multiple modes, students would be better able to adjust and improve their skill and knowledge development throughout the year, especially after two years of predominantly online learning due to the COVID-19 pandemic. We also explored whether clinical educators would be more confident to give targeted feedback to students in a way that yields positive change if they were provided with a model that can be used in different modes and for different activities. What we found was that the consistency and intentionality of the feedback was highly impactful, with face to face in real time feedback being more effective that video feedback. Having a feedback model improved feedback literacy and confidence for both students and educators.

Numerical simulation of non-Newtonian blood flow in a human arterial bifurcation model
Authors: Belkhiri Khellaf
Published: August 2024

Hemodynamic factors play a role in atherogenesis and the localization of atherosclerotic plaques. The human aorta and coronary arteries are susceptible to arterial disease, and there have been many studies of flows in models of these vessels. Atherosclerosis is a systemic disease occurring in specific sections of the cardiovascular tree such as the carotid and the coronary arteries. This paper aims to simulate the human arterial bifurcation and investigates some hemodynamic parameters as blood propagates from the aortic artery toward the carotid artery. We analyze the velocity, static pressure, shear stress. The simulation results showed disturbed flow patterns, such as flow separation and stagnation, as well as abnormal hemodynamic parameters (HPs) distributions including the low and high wall shear stress (WSS) and oscillation of wall shear stress. Based on our simulating characteristic results, the CFD tools can not only monitor the hemodynamic parameters obviously, but also help to analyze the diagnostic for the treatment of vascular diseases. CFD can be an effective technology for the examination and treatment of patients with failure of blood supply of the head and brain.

Gram-negative bacteria, such as Enterobacterales, can associate enzymatic resistance mechanisms, such
as beta-lactamase production, causing hard-to-treat infections. Genes encoding these enzymes are frequently
found on mobile genetic elements, which eases their spread. Carbapenemase production, but also other
enzymatic and non-enzymatic resistance mechanisms, individually or associated, may be responsible for
carbapenem resistance, and their correct identification is important for implementing the correct infection
control measures and, sometimes, choosing the right treatment.
For this article, disk-diffusion antibiograms were performed according to the EUCAST guidelines,
using a collection of well-characterized bacterial strains and various antibiotic disks, including certain ''key''
antibiotics. Supplementary, cloxacillin-infused Mueller-Hinton agar plates were used to differentiate AmpC
producers from non-producers phenotypically.
The phenotypic features that may be observed on the disk-diffusion antibiogram, which can help identify
and differentiate the production of the most common carbapenemases, alone or in combination with other
mechanisms, were described. For Ambler class A, KPC alone or combined with ESBL was presented; for
Ambler class B, NDM, VIM, and IMP enzymes were chosen, with emphasis on NDM and VIM with different
associations; and for Ambler class D, OXA-48 and one of the most problematic mutants, OXA-244, were
highlighted.
The disk-diffusion antibiogram is a cheap and easy-to-use tool with high diagnostic value when interpreted
correctly by the microbiology laboratory practitioner. This article represents the second part of a guide that
should help evaluate it.

With the rapid development of drone technology, the micro-Doppler signature plays a crucial role in the recognition and classification of drones. However, existing methods for extracting micro-Doppler signals are often affected by the complex structure of targets and environmental interferences, leading to issues of low extraction accuracy and efficiency. In response to this challenge, this paper investigates a method for extracting rotor micro-Doppler signals of Unmanned Aerial Vehicles (UAVs) based on electromagnetic simulation. By establishing the geometric model of the target object and using the physical optics method for RCS measurement of the model, the obtained data is utilized for inverse ISAR imaging to obtain the scattering center positions and scattering intensity of each point on the rotor. A model for extracting micro-Doppler properties is established, enabling accurate and efficient extraction of micro-Doppler characteristics for target objects. The proposed method can be widely applied to extract and study the micro-Doppler characteristics of different types of drones.

With the rapid development of technology, the Unmanned Aerial Vehicle (UAVs) are used in various fields, the most common of which are economic material transportation, military surveying, and data mapping in engineering. The powerful aircraft can ensure better power and load capacity, and the flight control system and high-precision navigation system of the UAV have accurate control algorithms and real-time monitoring capabilities of aircraft parameters. Firstly, before takeoff, safety checks including battery charging and equipment debugging will be carried out. After that, flight path planning and target location selection will be carried out according to the requirements of the delivery mission. After the successful delivery of the logistics drone, the delivery data will be reported in real time and automatic return. However, logistics drones also have some technical problems to be overcome, such as short battery life, low perception and obstacle avoidance. However, these problems can be solved by changing the fuselage material, improving the glide ability of the UAV, optimizing the fuselage impact point, and improving the HPSO algorithm framework. The promotion and application of logistics drones can effectively reduce part of the labor and labor costs, and at the same time, make the entire transportation work automated.

The purpose of this study was to assess the impact of transformational leadership practices on the organizational performance of some Ethiopian sports federations. Cross-sectional design was used to collect transformational leadership and organizational performance variables. The study was conducted in Addis Ababa City Administration, Ethiopia. The data was collected from Ethiopian sports federations participants (n = 95). Transformational leadership as a predictor variable measured by multifactorial leadership questionnaire and sport federation performance was measured by Australian national Olympic sporting organizations effectiveness. SPSS version 26 was used to process the data; robust method of multiple regression analysis was used to analyze the data p < 0.05. The result of the study shows that idealized influence was statistically significantly predicted organizational performance (β = .26, p = .00). However, that inspirational motivation (β = .03, p = .54), intellectual simulation (β = .11, p = .12) and individualized considerations (β = -.05, p = .49) did not significantly predicted organizational performance. The finding of the study shows that transformational leadership idealized influence enhanced the performance of selected Ethiopian sports federations through inspiring trust, fostering commitment, promoting excellence, and cultivating a positive organizational culture. Ethiopian Sports Federation managers were advised to consider transformational leadership style dimensions such as inspirational motivation, intellectual simulations and individual considerations in their leadership.
