Design, Development and Evaluation of Seaweed Drying Technology for Village Level Operation
Authors:   University of the Philippines Los Baños, Pangan Ronel , Ampo Mel Vincent , Barredo Ynno
Published: May 2024

A solar-type seaweed dryer was designed and developed to answer the needs of Filipino seaweed farmers for efficient and reliable drying technology. Through extensive baseline community surveys and field tests, the study was able to design a dryer prototype that is capable of drying high-grade quality seaweeds in a short amount of time. Moreover, geographical factors, natural hazard vulnerability, and farmers’ preference gave way for the development of two types of dryer: permanent and floating type. Both dryers were found to have positive effects in regards to drying time, product quality, streamlined operation, and overall economic benefits. Traditional drying practices takes around three (3) days to dry the seaweeds on good sunny days, but due to the varying weather conditions, the drying process can reach up to 7 days. The prolonged drying time, exposure to sudden downpours and contaminants greatly affects the quality of the seaweeds which in turn, compromises the market value of the dried seaweeds. The use of the drying technology remedied these problems inherent to traditional drying practices. To take full advantage on the use of the developed seaweed dryer, optimization experiments were conducted to determine the ideal settings of the dryer during daytime and nighttime conditions by varying the siding openings and operation of the exhaust fans. The optimization study resulted in a continuous and efficient drying operation under different weather conditions. Furthermore, field performance tests paved the way for the construction of a sturdier compact dryer design. Moreover, the incorporation of a solar-powered ventilation system and lighting system allowed continuous and efficient drying operation even during night time. Lastly, simple economic analysis also supported the profitability of drying technology in the long run.

Published: May 2024

Instrumented devices (ID) are useful for quantifying impact and vibration forces in postharvest supply chains of horticultural crops. In this study, a low-cost ID was developed capable of measuring impact force (G) and vibration. The ID was composed of an Adafruit Feather Adalogger microcontroller fitted with a triaxial accelerometer (± 200G range) shield and real-time clock stored time-stamped impact data in flash memory. A 3.7-volt lithium polymer battery served as the power source. The ID was encased in a semi-ellipsoidal shell fabricated from 3D-printed thermoplastic urethane (TPU95A) filament; the shell was printed at 25% fill density. The device weighed 80 g, which is representative of a medium-sized potato tuber. Drop tests showed a high correlation (R2 = 0923) between computed and measured peak acceleration in terms of G-force. The ID was tested by placing it in bulk-loaded potato tubers brought from Buguias to La Trinidad in Benguet province. GPS data was obtained using a mobile app to map the transport route and locate extreme impact events. Mean vibration of 1.18G intensity at 14Hz frequency was recorded throughout the 4-hour trip. Impact forces ranging from 4.6G to 6.61G were measured at certain points during transport. The device was assembled from commercially-available microcontrollers, sensors and other electronic components; total cost of fabrication was 94-98% less than comparable devices available in the market

Facility layout optimization is used to increase company productivity by minimizing waste on transportation, movement, and waiting time. It was mentioned in several previous studies that optimal facility layout can reduce production costs by up to 40%. Because of this importance, many previous researchers have carried out research in the field of Facility Layout. The differences between each Facility Layout research are in the characteristics and criteria being analyzed and the optimization method used. The several approaches used to optimize the layout are constructed algorithm, exact algorithm, and metaheuristic. These three methods have their respective purposes and to the best of our knowledge have not been used sequentially. So, this study aims to find the best layout for the double-row facility problem with aisle width consideration using three sequential methods. There are BLOCPLAN for the constructed algorithm, solver for the exact algorithm, and Particle Swarm Optimization (PSO) for the metaheuristic. The result shows that the use of BLOCPLAN gives a better result of Total Material Handling Cost (TMHC) in PSO. For more machines, PSO has better results than Gurobi Optimization.
Decido assim porque a sociedade pensa assim: a relação simbiótica estabelecida entre apelo social, midiatização de casos e a tomada de decisões discricionárias em Direito
Authors: Isaia Cristiano Becker , Obaldia Bruna Andrade
Published: May 2024

O presente trabalho busca investigar, dentro do grande tema da teoria das decisões judiciais, o desenvolvimento da relação entre clamor social, casos midiatizados e a tomada de decisões discricionárias em direito. Para isso, o ensaio se divide em duas grandes seções. Inicia-se pela compreensão do apelo da mídia enquanto retratante da vontade popular, agindo como fio condutor que transfere a tensão do direito às decisões judiciais discricionárias. O segundo capítulo, por sua vez, estuda como as influências midiático-populares determinam decisões nutridas de subjetividade e, assim, fortalecem o arraigamento do paradigma da filosofia da consciência no direito. Com base nisso, questiona-se: em que medida o apelo social e a midiatização de casos, enquanto aliados, podem figurar como protagonistas para o desencadeamento de respostas judiciais discricionárias? Para solucionar o problema de pesquisa, utiliza-se a abordagem fenomenológico-hermenêutica. Ao final do estudo, é possível concluir o apelo social e a midiatização de casos, enquanto aliados, podem figurar como protagonistas para o desencadeamento de respostas judiciais discricionárias na medida em que ambos fenômenos atuam simbioticamente na possibilidade de produção de subjetividade no contexto decisório, em muito alimentada pelo paradigma da filosofia da consciência no processo.

Authors: Chen Carie , Chen Carol , Lou Justin
Published: May 2024

Our project is centered on the concept of making music accessible to all individuals, including those with hearing impairments. Music can often play a large role in many lives, able to serve as a source of emotional comfort for many. As the numbers of hearingimpaired individuals rise significantly each year, it is important to enhance accessibility within their lives, including ways to experience the joy of music. By creating a device with vibrations and LED lights that sync with the beat/tempo of each song, this new way of music is easily accessible to all, especially to those with hearing impairments [7]. Leveraging our coding skills, we designed a program that could analyze a specific audio file. The analyzed information is then sent to our raspberry pi, connected to a haptic controller and LED lights through GPIO pins, this allows an easily accessible and functioning process for all users [8].

Published: May 2024

In this paper, we tackle the pressing communication gap between the Deaf and hearing communities, an issue affecting millions of individuals worldwide [1][2]. The proposed solution is a machine learning-powered application that translates sign language into text in real-time, allowing Deaf and hearing individuals to communicate directly [3]. The development faced challenges such as acquiring a diverse and accurate dataset and managing real-time processing of gestures. Experimentation involved testing the model's accuracy across multiple users, revealing promising outcomes. Two existing methodologies, a sensor-based glove and a single-camera solution, were compared, highlighting areas for potential enhancement in our approach. Despite the diversity of sign languages and their unique grammatical structures, the project represents a significant step towards more accessible communication. It highlights the potential for further advancement in machine learning applications for translation and inclusivity.

Cervical cancer is one of the most preventable cancers in the world and its` prognosis is better when detected early through cervical cancer screening. The study examined the knowledge, attitudes and practice regarding cervical cancer and screening among women visiting selected primary health centres (PHCs) in Ogbomosho. The study was conducted in May 2021, employing a descriptive cross-sectional design. A sample size of 124 respondents was determined using the Taro-Yamane formula and selected through convenience sampling technique. Data collection utilised a validated questionnaire, with analysis performed using descriptive statistics encompassing frequencies and percentages. Relationships between variables were tested using chi-square at a 0.05 significance level. Findings suggest that more than half (55%) had good knowledge of cervical and cervical cancer screening. The majority (70%) had a good attitude towards cervical cancer and cervical cancer screening. Less than one-third (21%) have had cervical cancer screening done before. Self-reported barriers limiting the practice of cervical cancer screening identified include lack of health education on cervical cancer screening (45.5%), lack of knowledge on the screenings (39.3%), absence of signs and symptoms of cervical cancer (39.3%), low socioeconomic status (29.5%), cost of the procedure (17.9%), unavailability of services (17.9%) and religious beliefs (14.3%). Chi-square analysis showed a statistically significant relationship between the educational status of respondents and their knowledge of cervical cancer screening, likewise, a significant relationship exists between the knowledge of respondents and the practice of cervical cancer screening at P< .05. Conclusively, the study has revealed the practice of cervical cancer screening was found to be low, indicating a disparity between knowledge/attitude and actual screening behaviour, although, knowledge was a key predictor of their screening practices. The way forward is to improve the knowledge of women on cervical cancer and screening via health education while efforts are being put in place to make cervical cancer screening services available at affordable cost.

Published: May 2024

This highlights the importance of exploring different calculation strategies and promoting meaningful learning, as recommended by the National Curriculum Parameters (PCNs). Despite this, many students face difficulties at the end of elementary school, showing a lack of understanding of mathematical concepts and their practical applicability. The Financial Education proposal aims to fill this gap by stimulating skills such as mental calculation, estimation and analysis of the reasonableness of results. However, the constant change of context in the exercises can make it difficult for students to understand. We therefore propose the use of tasks that stimulate the production of meanings by the students, allowing for different solving strategies and promoting discussion in the classroom. In this way, Financial Education as a cross-cutting theme in the mathematics curriculum aims to prepare students to face real-world challenges, promoting a broader and deeper understanding of mathematical concepts.

Authors: Ferreira Jéssica Lorrany Parente
Published: May 2024

The teaching of mathematics has undergone significant transformations, especially with the inclusion of games as an educational tool. Faced with contemporary challenges, education has had to reinvent itself, and games have proved to be powerful allies in this process. Through the playfulness and interactivity provided by games, students engage more actively and participatively in the learning process. In addition, games allow teaching to be personalized, meeting the individual needs of each student and promoting more meaningful learning. At the same time, games provide for the development of essential socio-emotional skills such as collaboration, critical thinking and problem solving. Technology also plays a key role in this context, offering access to a wide variety of educational resources. Thus, teaching math through games not only makes learning more interesting and motivating, but also prepares students for the challenges of the 21st century, empowering them to think critically, solve complex problems and collaborate effectively in an ever-changing world.

LEI GERAL DE PROTEÇÃO DE DADOS PESSOAIS: RESPONSABILIDADE CIVIL NO VAZAMENTO DE INFORMAÇÕES
Authors: Oliveira Larissa de Jesus , Novais Thyara Gonçalves
Published: May 2024

A proteção e a segurança dos dados pessoais têm sido um tema cada vez mais relevante na sociedade contemporânea, sobretudo pelo avanço das tecnologias de informação e comunicação. Nesse contexto, o vazamento de dados pessoais é uma preocupação crescente, demandando do poder jurisdicional a implementação da Lei Geral de Proteção de Dados Pessoais (LGPD), atualmente em vigor no Brasil. Este artigo busca analisar a responsabilidade civil das empresas em casos de vazamentos de dados pessoais, no contexto da LGPD. A fim de trazer mais clareza ao tema proposto, inicialmente, serão abordados os fundamentos da LGPD e as diretrizes estabelecidas pela legislação para o tratamento de dados pessoais, evidenciando a necessidade de proteção dessas informações e os direitos dos titulares. Além de realizar uma análise da responsabilidade civil das empresas em casos de vazamentos de dados pessoais, considerando a conduta adotada pelas empresas na proteção dessas informações e os possíveis danos causados aos titulares dos dados. Serão também destacadas as medidas preventivas que as empresas devem adotar para evitar vazamentos, como a implementação de políticas de segurança da informação e o treinamento de funcionários. Além disso, será examinada de forma lacônica a aplicação coercitiva às empresas que descumprirem a LGPD, através do entendimento jurisprudencial e doutrinário de julgados nos tribunais brasileiros. A pesquisa realizada evidencia que apesar da LGPD representar um marco importante para a proteção de dados no país, sua efetividade esbarra diante de lacunas existentes na legislação, demonstrando uma fragilidade quanto à determinação da culpa, quantificação dos danos e a identificação dos responsáveis.
O BENEFÍCIO DE PRESTAÇÃO CONTINUADA E SUA FUNÇÃO SOCIAL
Authors: Sousa Lucas Bandeira de , Abreu Sergio Marcos de Brito
Published: May 2024

O Benefício de Prestação Continuada (BPC) é um importante meio assistencialista que veio auxiliar dois grupos muito vulneráveis da sociedade: os idosos e os deficientes. Esses grupos são em sua maioria, compostos por pessoas que vivem à margem de uma sociedade jovem e adulta atuante, e que por essa razão necessitam de apoio e cuidado, principalmente do Estado. Nesse sentido, o objetivo desse estudo foi analisar o impacto econômico nos cofres públicos e também na sociedade, na vida de quem recebe o benefício. No campo metodológico, foi realizada uma revisão bibliográfica, com fundamento em artigos científicos, livros, periódicos, jurisprudência e na legislação atual sobre o respectivo tema. A coleta de dados foi feita por meio de banco de dados tais como Scielo, Google Acadêmico, dentre outros, no período de 2018 a 2023. Nos resultados, evidenciou-se que apesar de ser importante e contribuir para a redução da pobreza, o estímulo ao consumo, a inclusão social e o bem-estar geral da sociedade, o Benefício de Prestação Continuada tem um impacto econômico significativo, aumento os custos do Governo Federal, possuindo um valor limitado, criação de dependência dos beneficiários, está sujeito a fraudes e irregularidades, etc. É necessário equilibrar a necessidade de fornecer assistência aos grupos mais vulneráveis da população com as demandas orçamentárias globais e a sustentabilidade financeira do programa. Portanto, a administração eficaz e a fiscalização rigorosa são fundamentais para garantir que o BPC atinja seus objetivos sociais e econômicos de maneira eficiente.

Sparse matching via point and line feature fusion for robust aerial triangulation of photovoltaic power stations’ thermal infrared imagery
Authors: Ke Tao , Ye Zhouyuan , Zhang Xiao , Liao Yifan , Tao Pengjie
Published: May 2024

Abstract. In this paper, we present a novel matching method tailored for unmanned aerial vehicle (UAV) thermal infrared images of photovoltaic (PV) panels characterized by highly repetitive textures. This method capitalizes on the integration of point and line features within the image to obtain reliable corresponding points. Furthermore, it employs multiple constraints to eliminate mismatched features and get rid of the interference of repetitive textures on feature matching. To verify the effectiveness of the proposed method, we used an UAV equipped with the DJI Zenmuse H20T thermal infrared gimbal to capture 3767 images of a PV power station in Guangzhou, China. Experiments demonstrate that, for UAV thermal infrared images of PV panels, our method outperforms the state-of-the-art techniques in terms of the density of matching points, matching success rate and matching reliability, consequently leading to robust aerial triangulation results.
Efficient Feature Matching for Large-scale Images based on Cascade Hash and Local Geometric Constraint
Authors: You Kan , Jiang San , Li Yaxin , Jiang Wanshou , Huang Xiangxiang
Published: May 2024

Abstract. Feature matching plays a crucial role in 3D reconstruction to provide correspondences between overlapped images. The accuracy and efficiency of feature matching significantly impact the performance of 3D reconstruction. The widely used framework with the exhaustive nearest neighbor searching (NNS) between descriptors and RANSAC-based geometric estimation is, however, low-efficient and unreliable for large-scale UAV images. Inspired by indexing-based NNS, this paper implements an efficient feature matching method for large-scale images based on Cascade Hashing and local geometric constraints. Our proposed method improves upon traditional feature matching approaches by introducing a combination of image retrieval, data scheduling, and GPU-accelerated Cascade Hashing. Besides, it utilizes a local geometric constraint to filter matching results within a matching framework. On the one hand, the GPU-accelerated Cascade Hashing technique generates compact and discriminative hash codes based on image features, facilitating the rapid completion of the initial matching process, and significantly reducing the search space and time complexity. On the other hand, after the initial matching is completed, the method employs a local geometric constraint to filter the initial matching results, enhancing the accuracy of the matching results. This forms a three-tier framework based on data scheduling, GPU-accelerated Cascade Hashing, and local geometric constraints. We conducted experiments using two sets of large-scale UAV image data, comparing our method with SIFTGPU to evaluate its performance in initial matching, outlier rejection, and 3D reconstruction. The results demonstrate that our method achieves a feature matching speed 2.0 times that of SIFTGPU while maintaining matching accuracy and producing comparable reconstruction results. This suggests that our method holds promise for efficiently addressing large-scale image matching.
360-Degree Tri-Modal Scanning: Engineering a Modular Multi-Sensor Platform for Semantic Enrichment of BIM Models
Authors: Collins Fiona C. , Noichl Florian , Slepicka Martin , Cones Gerda , Borrmann André
Published: May 2024

Abstract. Point clouds, image data, and corresponding processing algorithms are intensively investigated to create and enrich Building Information Models (BIM) with as-is information and maintain their value across the building lifecycle. Point clouds can be captured using LiDAR and enriched with color information from images. Complementary to such dual-sensor systems, thermography captures the infrared light spectrum, giving insight into the temperature distribution on an object’s surface and allowing a diagnosis of the as-is energetic health of buildings beyond what humans can see. Although the three sensor modes are commonly used in pair-wise combinations, only a few systems leveraging the power of tri-modal sensor fusion have been proposed. This paper introduces a sensor system comprising LiDAR, RGB, and a radiometric thermal infrared sensor that can capture a 360-degree range through bi-axial rotation. The resulting tri-modal data is fused to a thermo-color point cloud from which temperature values are derived for a standard indoor building setting. Qualitative data analysis shows the potential for unlocking further object semantics in a state-of-the-art Scan-to-BIM pipeline. Furthermore, an outlook is provided on the cross-modal usage of semantic segmentation for automatic, accurate temperature calculations.
Comparing Deep Learning and MCWST Approaches for Individual Tree Crown Segmentation
Authors: Fan Wen , Tian Jiaojiao , Troles Jonas , Döllerer Martin , Kindu Mengistie , Knoke Thomas
Published: May 2024

Abstract. Accurate segmentation of individual tree crowns (ITC) segmentation is essential for investigating tree-level based growth trends and assessing tree vitality. ITC segmentation using remote sensing data faces challenges due to crown heterogeneity, overlapping crowns and data quality. Currently, both classical and deep learning methods have been employed for crown detection and segmentation. However, the effectiveness of deep learning based approaches is limited by the need for high-quality annotated datasets. Benefiting from the BaKIM project, a high-quality annotated dataset can be provided and tested with a Mask Region-based Convolutional Neural Network (Mask R-CNN). In addition, we have used the deep learning based approach to detect the tree locations thus refining the previous Marker controlled Watershed Transformation (MCWST) segmentation approach. The experimental results show that the Mask R-CNN model exhibits better model performance and less time cost compared to the MCWST algorithm for ITC segmentation. In summary, the proposed framework can achieve robust and fast ITC segmentation, which has the potential to support various forest applications such as tree vitality estimation.

Assessment of Maximum Oxygen Uptake in Elite Youth Soccer Players: A Comparative Analysis of Smartwatch Technology, Yoyo Intermittent Recovery Test 2, and Respiratory Gas Analysis
Authors: Düking Peter , Ruf Ludwig , Altmann Stefan , Thron Maximiliane , Kunz Philipp , Sperlich Billy
Published: May 2024

The maximum oxygen uptake (VO2max) is a critical factor for endurance performance in soccer. Novel wearable technology may allow frequent assessment of V̇O2max during non-fatiguing warm-up runs of soccer players with minimal interference to soccer practice. The aim of this study was to assess the validity of VO2max provided by a consumer grade smartwatch (Garmin Forerunner 245, Garmin, Olathe, USA, Software:13.00) and the YoYo Intermittent Recovery Run 2 (YYIR2) by comparing it with respiratory gas analysis. 24 trained male youth soccer players performed different tests to assess VO2max: i) a treadmill test employing respiratory gas analysis, ii) YYIR2 and iii) during a non-fatiguing warm-up run of 10 min wearing a smartwatch as recommended by the device-manufacturer on 3 different days within 2 weeks. As the device-manufacturer indicates that validity of smartwatch-derived VO2max may differ with an increase in runs, 16 players performed a second run with the smartwatch to test this claim. The main evidence revealed that the smartwatch showed an ICC of 0.37 [95% CI: -0.25; 0.71] a mean absolute percentage error (MAPE) of 5.58% after one run, as well as an ICC of 0.54 [95% CI: -0.3; 8.4] and a MAPE of 1.06% after the second run with the smartwatch. The YYIR2 showed an ICC of 0.17 [95% CI: -5.7; 0.6]; and MAPE of 4.2%. When using the smartwatch for VO2max assessment in a non-fatiguing run as a warm-up, as suggested by the device manufacturer before soccer practice, the MAPE diminishes after two runs. Therefore, for more accurate VO2max assessment with the smartwatch, we recommend to perform at least two runs to reduce the MAPE and enhance the validity of the findings.
Desautomatización fraseológica y humor verbal en español
Authors: Silvestre Miralles Alicia
Published: May 2024

Los refranes, frases hechas y fórmulas rutinarias son unidades léxicas pluriverbales (Corpas Pastor, 1996) que muestran mayor fijación e idiomaticidad, lo que las convierte en marco ideal para insertar rupturas de la expectativa. El presente artículo aborda un conjunto de refranes desautomatizados, esto es, sometidos a variación, ruptura o desvío, con fines humorísticos. En el marco de las teorías de análisis del humor verbal tomamos las más recientes ampliaciones y aplicaciones al español de la Teoría General del Humor Verbal (Raskin & Attardo, 1991; Attardo, 2020) por parte de Ruiz Gurillo (2019). Analizamos los procedimientos empleados para desautomatizar algunos refranes en inglés y español: el orden de los constituyentes, variación de la categoría gramatical, modificación del número de elementos, sustitución de componentes (Montoro, 2005). Para el análisis de la desautomatización de refranes se consideran los trabajos de Veyrat Rigat (2008), Luque (2008), García Yelo (2012) e Illán Castillo (2021). Se observan patrones comunes en los tipos de ruptura en el plano lingüístico que confirman la tesis de Corpas Pastor (1996: 29) de que, cuanto más fija es la unidad fraseológica, más factible es que se la modifique en el discurso.

El propósito de este trabajo es identificar los encuadres léxicos dominantes en los editoriales sobre la guerra de Cuba publicados a lo largo de 1898, en tres de los principales diarios de la prensa española: El Imparcial, El Liberal y Heraldo de Madrid. El periodismo ejercía entonces una gran influencia en las decisiones políticas. Además, constituía el único medio con el que contaba la sociedad para informarse sobre los sucesos ultramarinos, de ahí su relevancia para moldear la opinión pública. El uso de un software de análisis de corpus nos ha permitido llevar a cabo un análisis cuantitativo de los sustantivos más recurrentes y detectar los campos semánticos de mayor relevancia. Además, el análisis contrastivo nos ha permitido conocer la evolución experimentada por la línea editorial de cada diario a lo largo de las distintas etapas de este conflicto bélico. Por tanto, esta investigación puede ayudar a dilucidar cuál fue la responsabilidad de la prensa en el enfrentamiento entre España y los Estados Unidos.
Coordinación y subordinación discursivas en la columna periodística
Authors: Garrido Medina Joaquín
Published: May 2024

Para dar cuenta de la coordinación discursiva discursiva en la argumentación de la columna periodística, se propone una estructura de la oración como constituyente de una estructura más amplia del discurso. Las oraciones son unidades de discurso conectadas a otras unidades en un proceso en que su contexto discursivo proporciona la información requerida para construir una estructura de constituyentes del discurso. La coordinación con y en posición inicial tiene propiedades de subordinación a la izquierda en la estructura de constituyentes del discurso. Estas propiedades se analizan en términos de sus características de foco y tópico. Se muestra que la coordinación y subordinación discursivas constituyen un medio eficaz para construir unidades de discurso intermedias que representan movimientos argumentativos en las columnas de opinión.
Comunicación y norma: la aplicación de la modernización del sistema ortográfico español en la prensa malagueña del siglo XIX
Authors: Peláez Santamaría Salvador
Published: May 2024

La ortografía española en el siglo xix vive una época de intensos debates y cambios en relación con la estandarización y regulación de la escritura. Durante este período, se llevan a cabo numerosos esfuerzos por establecer normas claras y uniformes para la correcta escritura del idioma español, y la prensa se convierte en un aliado especial para su divulgación. En este artículo, se contextualiza la situación lingüística, se realiza una descripción de la situación de la prensa en general y particular y se analizan los principales cambios realizados en la ortografía española en el siglo xix, destacando las normativas más importantes y las influencias que tuvieron en la prensa decimonónica de la ciudad de Málaga, con la finalidad de comprobar el grado de consecución de las mismas y conocer, así, el conocimiento de las normas ortográficas que tenían los editores e impresores locales.
[en] Exploring safety and agency in social media: a case study of online crossdressing
Authors: Boneta Nerea , Fuentes Anita
Published: May 2024

Introduction. Are there safe spaces for the construction of online communities with diverse gender identities and sexual desires? What makes some online spaces safer than others? And for whom? Does the architecture of these spaces influence the ways in which users navigate the Internet? Methodology. To address these questions, we conducted a digital ethnography on a social media platform oriented towards the Spanish-speaking crossdresser community. Findings and analysis. Our analysis suggests that this platform acts as a digital counterpublic, as it allows users to inhabit a safe environment for self-expression, building support networks, organizing as a collective, and articulating their sexual intimacies. Based on these findings, we infer that online safety and agency are closely interrelated, the latter being a result of the first. In addition, we found that the concept of online safety should be evaluated on a case-by-case basis, in accordance with the feminist perspective, where online safety is always construed in a situated manner and conceives the subjects of study as active agents involved in the definition of the concept itself. Ethical considerations. The research process raised ethical questions of great relevance to the conclusions of this study, suggesting that the same factors to be considered when conducting research in digital platforms should be contemplated when designing and navigating online safe spaces. We thus propose that, both in carrying out online qualitative research and in the construction of online safe spaces, the following aspects should be taken into consideration: the implications of the privacy settings offered by the platform, the vulnerability of the users that populate it, the sensitivity of the topics covered by the platform’s community and, last but not least, an ongoing negotiation and reaffirmation of consent in the utilization of the users’ personal data.
La Comunicación como aspecto esencial en la transmisión de estereotipos: una aproximación al modelo de feminidad según Fallaci
Authors: Ballesteros-Aguayo Lucia
Published: May 2024

Introducción. Profundizar en el origen de los estereotipos de género ha sido uno de los objetivos del feminismo desde su origen. Así la desigualdad sexual para Beauvoir se origina a partir del ´mito` de feminidad que ha perpetuado una sociedad androcéntrica históricamente hegemónica, de ahí que su objetivo sea el igualitarismo. El feminismo evolucionó hacia otros como el de la diferencia que, contrariamente, pretende preservar las diferencias sexuales. Objetivos y metodología. Nuestro trabajo mostrará una nueva faceta que Oriana Fallaci denomina Feminismo Avanzado a partir del análisis de la crónica relatada en El segundo sexo en la que, sin polemizar con el de la igualdad, se aproxima al feminismo de la diferencia y al feminismo radical, y considera que los estereotipos se generan en el seno del patriarcado (no existe una sociedad libre de ellos) y todos derivan del triple origen familiar, social y comunicativo que interviene en los procesos de socialización, también en las sociedades matriarcales. Resultados. Funcionalmente la original combinación de las perspectivas émica y ética propias de la antropología cultural permite concluir en Fallaci la existencia de un universo simbólico que refuta tanto el estereotipo de la inutilidad femenina en sociedades exóticas, como la autonomía y progreso en otras sociedades. Conclusiones. Metodológicamente el método analógico aplicado a la moda como símbolo de dominación patriarcal muestra que Fallaci se aleja de Beauvoir cuando concluye que más allá de la rigidez y cosificación que denuncia el feminismo de la igualdad, tras la moda se ocultan motivaciones económicas, exóticas o culturales que la convierten en útil y, con ella, a las mujeres. Adicionalmente Fallaci muestra que el triple origen del estereotipo provee tanto a mujeres como a varones de modelos axiológicos, estéticos y cognitivos propios de cada cultura en los que se transmite no solo la feminidad, sino también la masculinidad, y en los que la publicidad turística en particular, y los medios de comunicación en general, colaboran en la difusión de sus modelos identitarios.
Redescubriendo a Charlotte Perkins Gilman: Aportaciones precursoras para una Sociología feminista
Authors: Jiménez Rodrigo María Luisa
Published: May 2024

Introducción/Objetivos: La enseñanza de la Sociología, aún hoy, arrastra un marcado componente androcéntrico que tiende a invisibilizar e infravalorar las aportaciones de las mujeres como productoras de conocimiento y de teoría social. Este sesgo es especialmente patente en el período clásico y fundacional de la disciplina. Entre las sociólogas olvidadas del canon sociológico destaca Charlotte Perkins Gilman (Estados Unidos, 1860-1935). En este trabajo se pretende recuperar su figura mostrar sus aportaciones precursoras para la configuración de una Sociología feminista. Metodología: Se ha realizado una revisión de la literatura sobre su obra junto a una revisión de sus escritos principales, especialmente Mujeres y economía. Resultados: La obra de Gilman, respecto a la de sus coetáneos sociólogos, representa un planteamiento único y alternativo de análisis de las relaciones sociales, situando al género como eje clave de la estratificación social. Anticipa ideas clave para el análisis sociológico y feminista, y desarrolla un marco multidimensional de análisis de las relaciones de dominación de género en base a la interacción de factores económicos y culturales. Presenta además un proyecto de reforma social para la emancipación femenina, señalando la importancia del conocimiento para la transformación social. No obstante, su pensamiento también ha recibido críticas respecto a algunos argumentos escasamente aplicables en la actualidad. Discusión y contribución: El redescubrimiento de las sociólogas pioneras, además de ser una cuestión de justicia académica, contribuye a pensar nuestra disciplina desde una perspectiva diferente, más inclusiva, más crítica, reflexiva e innovadora, y más abierta hacia otros modos posibles de aprender y practicar la Sociología.

Published: May 2024

Introducción. La soldadura es un proceso por el cual dos o más materiales, generalmente metálicos, se unen mediante fusión, calentamiento y/o presión. A pesar de ser un proceso industrial principalmente dirigido, practicado e investigado por colaboradores masculinos, la participación de las investigadoras en el tema ha ido en aumento. Objetivos. A través de un análisis cuantitativo empleando herramientas de bibliometría se ha podido evidenciar la participación de investigadoras en México en los diferentes procesos de soldadura industrial existentes. Metodología. Se empleó la base de datos Scopus con el fin de contabilizar dicha participación en temas de soldadura. Resultados y discusión. Fue contabilizada una participación de menos del 12% contemplando años de producción de 1985 a 2022, adicionalmente se lograron detectar las dos áreas temáticas con mayor producción, incluso aquellas que poseen aplicación en soldadura y que han tenido un gran impacto industrial. Conclusión. Para efectos de una mayor participación en la comunidad científica en el campo de la soldadura, conocer y crear conciencia sobre la importante contribución que realizan las mujeres en temáticas industriales.
