Published: March 2024

The brain is one of the most sensitive parts of the human body which
transmits millions of signals every moment. Dementia is the most emerging brain
health issue which involves memory loss, difficulty in problem-solving, handling
complex tasks, etc. Dementia is a syndrome that causes a loss of mental ability. It
affects memory, thinking, shape, comprehension, counting, reading ability, language,
and judgment. Dementia affects millions of people and can be the leading cause of
death. It is now the seventh leading cause of death worldwide, as well as one of the
major causes of impairment and reliance on elderly people. There is no treatment for
dementia at present. The importance of early detection and diagnosis in improving
early and effective management is crucial. Predicting dementia in advance can lead us
to a better life. To predict dementia, various Machine Learning models have been used.
In this paper, Dementia is predicted on the basis of MRI Images, for this, three
different datasets of MRI Images have been collected. Furthermore, for better
prediction, various Machine learning models are used to predict dementia and validate
the performance with statistical analysis like K-Nearest Neighbours, XG Boost,
Support Vector Machine, Random Forest Algorithm (RFA), and Convolutional Neural
Network (CNN). Out of all algorithms, Random Forest Algorithm and Convolutional
Neural Network gave the best result with the accuracy of 93.2 and 99.9 respectively.

The triple glass ceiling: FinTech gender inequalities
Authors: Fox-Robertson Chloe , Wójcik Dariusz
Published: March 2024

While FinTech gets promoted as an innovative and progressive solution to meeting financial needs globally, it is afflicted by pervasive gender inequalities, only recently noticed in research. To explore these gender inequalities at the core of FinTech, we use a mixed-methods approach, combining data on 100 leading FinTech firms and 15 interviews with FinTech professionals, collected in the latter half of 2021. We argue that women in FinTech face the ‘triple glass ceiling’ at the intersection of financial, technological, and entrepreneurial gender inequalities. Our sample shows that women account for only 7.69% of (co-)founders, 18.2% of executive committee members, and merely 4.04% of FinTech companies are led by a woman. Gendered stereotypes and a privileging of masculine performances produce significant barriers to women entering and progressing within FinTech. Discriminatory practices are overt and implicit, everyday and exceptional, micro and acute. Shattering the ‘triple glass ceiling’ in FinTech represents an immense challenge.
Real estate financialisation and the production of ‘investable’ spaces in Johannesburg
Authors: Schultz Cecilia
Published: March 2024

This article contributes to an understanding of how real estate financialisation unfolds within a city in the global South, Johannesburg. It firstly shows that compared to what has been witnessed in the global North, real estate financialisation in South Africa is characteristically conservative: market actors do not engage in high-risk, low-income neighbourhoods. Indeed, in Johannesburg, financialisation has displayed minimal interest in residential markets. Instead, financialisation in the city has been driven by commercial property investments, typically in the form of urban enclaves such as securitised office parks, malls, mixed-use developments, and increasingly ‘satellite cities’ built from scratch. This article considers how the selective character of financialisation in the country is mediated by power relations in the global political economy. In particular, it highlights how South Africa’s status as an ‘emerging market’ encourages a prudent lending regime for domestic financial institutions and real estate actors.
Shaping the climate transition: Multistakeholder networks, elites, and sustainable finance policy in Europe
Authors: Tischer Daniel , Ferrando Tomaso
Published: March 2024

As sustainable finance has entered the mainstream, it has become an area of contestation among civil society, political and business. In response, policy makers seek to resolve stalemates and enhance legitimacy by utilising multistakeholder, consensus-driven approaches to policymaking. In this paper, we examine these emergent ‘cooperative’ structures from a network analytic perspective. Our structural analysis is based on six national and three EU policy spaces. We conduct compositional analyses to explore the makeup of the network(s) and use a range of centrality measures to capture emerging elites. We find an increase in civil society participation in these policy spaces over time; however, financial firms and pro-business voices remain dominant players. We also find a small cluster of elite actors from a range of stakeholder groups. We conclude that the increasing structural balance of stakeholder interests, however, does not translate into power for civil society to alter the direction of policymaking, but appears to serve enhancing the legitimacy of a policy process that departs from the priority and aspirations of civil society organisations.
Cultura digital y percepción de los estudiantes de la UNAM sobre los procesos de enseñanza-aprendizaje en línea durante la pandemia COVID-19
Authors: Perera Ramos Rodrigo , Dorantes y Aguilar Gerardo L.
Published: March 2024

Los resultados que se muestran en esta publicación —y que son parte de una investigación más amplia— revelaron que, en general y desde la percepción del alumnado, los procesos de enseñanza-aprendizaje no se vieron afectados por la pandemia COVID-19. No obstante, estos hallazgos develan que una mayor afección educativa residió en los componentes de esos procesos que exigen una interacción social inherente como los son la comunicación entre pares (profesores y autoridades) y, sustancialmente, las clases. En este sentido, los datos permiten afirmar que las tecnologías digitales no tienen ni las capacidades ni la calidad de las interacciones cara a cara a pesar de que sean propiamente de interacción. Sin embargo, en las actividades de los procesos de enseñanza-aprendizaje que no requieren de una interacción social la calidad se vio mejorada, como es el caso de la realización de trabajos y tareas, de la organización de los tiempos de estudio y, particularmente, la obtención y búsqueda de bibliografía, entre otros recursos académicos. En suma, el quebranto de algunos componentes de los procesos de enseñanza-aprendizaje, así como el progreso de otros, pudieron generar un balance en estos procesos, lo que permitió que de forma general los estudiantes no se vieran afectados de forma significativa durante las clases totalmente en línea, obligadas por la emergencia sanitaria. No obstante, estos resultados no podrían ser iguales en un contexto de brechas digitales amplias, de poca cultura digital y con una apropiación nula o débil de las tecnologías computarizadas.
Effect of cetyltrimethylammonium bromide on flocculation and filtration of bentonite suspensions
Authors: Nakamura A. , Sato H. , Sato Y. , Murakami K.
Published: March 2024

Separation of bentonite from wastewater is challenging because bentonite, is highly dispersible in water. Using cationic polymer flocculants has a high flocculation effect on bentonite. However, the flocculation mechanism is unclear. In this study, flocculation, filtration, and bentonite adsorption behavior are investigated using cetyltrimethylammonium bromide (CTAB) as cationic small molecule; subsequently, the flocculation mechanism of bentonite is explored. The flocculation effect increases and the filtration time is reduced with increasing CTAB concentration. In particular, when more than 1500 ppm of CTAB is used, the filtration time is reduced to 2–3 min. Bentonite forms secondary flocculates after the formation of primary flocculates with increasing CTAB concentration. Additionally, the adsorption behavior reveals that CTAB is inserted between the layers, and it is excessively adsorbed on the bentonite surface. The increase CTAB concentration was effective in improving the shortening the filtration time owing to the formation of large bentonite flocculates.

Published: March 2024

In this research, the effects produced by the combination of coffee husk ash and polypropylene fibers in the production of concrete were studied in order to evaluate the mechanical properties and determine an optimum design combination. Two standard concrete mix designs of f'c= 210 and 280 kg/cm2 were developed, and experimental treatments of standard concrete were designed by adding coffee husk ash at 5%, 10% and 15% combined with polypropylene fibers at 1%, 2.5 % and 5%. The results showed that the resistance differs in 8.94% and 4.11% in compression, 8.55% and 15.03% in traction, 10.89% and 8.96% in bending and increases the modulus of elasticity in 5.66% and 14.15% with respect to the standard designs f'c= 210 and 280 kg/cm2. It is concluded that the mechanical characteristics are relatively lower compared to the standard mix designs.

Published: March 2024

Due to its potential to improve production and weld quality, automated welding systems are growing in popularity in industrial applications. However, these technologies generate potentially dangerous by-products like welding gases and fumes. By evaluating the temperature range and smoke concentration near the welding area, this study intends to assess the health parameters of welding by-products in linear welding automation. A four-wheeled robot system equipped with joint detection and referencing technologies will be the research subject, which will also improve welding conditions to match industrial standards. Also, the study will look into how welding factors affect smoke concentration and temperature range. The findings of this study will shed light on the health risks posed by automated welding systems and guide the creation of safety regulations that will shield workers from hazardous consequences.

This experimental research aimed to develop a conductive polymer composite (CPC) material for electromechanical devices. The composite was made by incorporating conductive micro carbon derived from rice husks into a Linear Low-Density Polyethylene (LLDPE) polymer matrix using hot compaction. Variations of filler composition were used, with carbon loading of 50%, 45%, and 40%, and mesh sizes of #150, #200, and #250. The experimental results showed that particle size variations did not significantly affect composite density, but higher mesh selection improved filler dispersion within the matrix, resulting in higher electrical conductivity values. The optimal conductivity value of 9.43E-04 S/cm was achieved with a micro-carbon composition of 50% loading. However, decreasing micro carbon loading had a more significant impact on reducing electrical conductivity values.

China and its Development Model: A Broad Outline from a Mexican Perspective
Authors: Héctor Arturo Oropeza García
Published: March 2024

China’s economic success from 1978 to 2008 is truly surprising, for example the growth rate of its GDP (an average of 10% a year for thirty years, third place in the world in 2008, 14 times its GDP from 1978 to 2007). However, we could also add that China’s economic history is very far from being over, and in the future it will continue surprising us with its innovations, which it will have to keep in mind if it wants to have a close idea of the most successful development strategy of recent decades.
An Overview of the Rules Governing the Performance of Public Middle School Teachers in Mexico City
Authors: Jorge Luis Silva Méndez
Published: March 2024

Rules governing the performance of public middle school teachers in Mexico City are contained in a myriad of regulations, a fact which leads to certain difficulties in understanding them. This article analyzes them based on a detailed review of the relevant laws and interviews with the public officers who enforce these provisions. Teacher performance rules are divided into three groups depending on the type of activity regulated: performance in the classroom, discipline, and attendance/punctuality. The comment also provides a brief explanation of the remedies for sanctions imposed on teachers by the educational authorities, and explains the nature of the termination lawsuit before the Federal Court of Conciliation and Arbitration.

Fotografía de Andrés Boero Madrid
Authors: Boero Madrid Andrés
Published: March 2024

En su obra, Andrés Boero expresa el carácter transitorio del ser humano observando las transformaciones de la cultura y de la naturaleza en el lugar que habita: la desembocadura de un río. Deconstrucción es un proyecto que indaga sobre su relación directa con el paisaje, punto de partida y fuente de inspiración, donde el proceso creativo cobra mayor relevancia que el resultado final. A través de diferentes caminatas por la villa, las orillas del río, los humedales y el monte, Boero observa cómo la naturaleza y el hombre se modifican recíprocamente.

Del desplazamiento por el territorio surge el contacto con lo matérico: el barro, la madera y su mutación por medio del agua, aire y fuego. Telas instaladas en el río, en el suelo, debajo de los árboles, para ver cómo el ambiente se expresa y deja su marca en ellos. Troncos encontrados, modificados por el agua y luego por las manos del artista. El barro también cobra gran relevancia en la obra de Boero, como un material que denota la temporalidad, que está en constante transición, determinado por la ausencia y presencia del agua. Deconstrucción es una práctica de observación y aprendizaje a través del territorio, en busca de una formalidad abstracta, sin idea preestablecida más allá del encuentro con el entorno. Casi a modo de boceto, las fotografías son el testimonio de un proceso, que es la obra en sí.

Este proyecto fue apoyado por los Fondos Regionales para la Cultura del Ministerio de Educación y Cultura (2017) y desarrollado durante 2018. La obra ha sido expuesta en el Museo Municipal Profesor Roselli de Nueva Palmira (Uruguay) y en el Museo Lacán Guazú de Dolores (Uruguay).

Andrés Boero Madrid, Uruguay, 1983. Cineasta y Artista visual, con su trabajo reflexiona sobre el hombre y el paisaje desde la identidad y memoria latinoamericana. Es graduado como Director de Fotografía de la Escuela Internacional de Cine y Televisión de San Antonio de los Baños, Cuba. Ha expuesto en diferentes espacios culturales, como el Museo Nacional de Artes Visuales, Museo Lacán Guazú, Espacio de Arte Contemporáneo y Centro de Exposiciones Subte. En la actualidad lleva adelante un proyecto de residencia para artistas en Villa Soriano, un pequeño pueblo del interior uruguayo, promoviendo la descentralización de la producción artística contemporánea (vatelon.com).

Siento la fotografía como una herramienta para transmitir emociones. Me gusta el vínculo directo que tiene con la realidad. Defiendo la condición de huella de luz del mundo que nos rodea y busco a partir de lo que existe, de lo que veo, componer imágenes que inspiren algo: alegría, tristeza, soledad, amor... Imágenes que tienen al ser humano, y su relación con el entorno, como centro. Es en el documentalismo y en el fotoperiodismo donde siento que está mi campo de acción y donde encuentro a los fotógrafos que admiro.
La cobertura social de la prensa diaria en Uruguay

Published: March 2024

¿Cómo debemos pensar lo social según los diarios uruguayos? ¿Con qué perspectiva? ¿Cuáles son los temas sociales que la prensa considera más relevantes? ¿Qué espacio les concede? ¿Con qué enfoque? ¿Quiénes son los protagonistas de las informaciones sociales? ¿Cuáles son las fuentes que consultan los diarios para problematizar los asuntos sociales? Estas preguntas importan, ya que la forma en que los temas son tratados por la prensa influye en cómo la opinión pública los percibe.En este artículo presentamos las conclusiones de una investigación descriptiva, de carácter cuantitativo, sobre la cobertura de los temas sociales en la prensa montevideana. Esta fue desarrollada por un equipo de docentes y estudiantes de la Facultad de Comunicación de la Universidad de Montevideo, durante el primer semestre de 2008.
