A promising line of research in construction science and practice is the creation of lightweight concretes. They exhibit the so-called strength-density ratio, i. e. a relative characteristic between the strength and weight of the resulting concrete. This ratio simultaneously reflects the maximum possible weight reduction of the structure and its operational reliability. The research aims to compare the effectiveness of microsilica modification of lightweight concretes produced with coarse aggregates from various rocks. The study analyzed the existing scientific literature on lightweight concretes, their formulations, technology, and scientific validity, as well as the structural compatibility of the components used. A comparison was made of the effectiveness of lightweight concrete modification for various formulation technological parameters. The strength of modified lightweight concrete and its strengthdensity ratio changed significantly compared to unmodified lightweight concrete. The strongest effect is achieved when using lightweight granite concrete modified with 9 % of microsilica. As a result, the maximum compressive strength was 55.9 MPa, and the strength-density ratio was 24.3•10-3 MPa•m3/kg compared to other studied concrete compositions. The increase in compressive strength was 17.2 % compared to unmodified lightweight concrete. The strength-density ratio increased by 19.1 % compared to unmodified coarse dense aggregate concrete.

Typha australis is an invasive plant from Senegal that is also found in wetlands. In order to limit its proliferation, Typha australis is used in the energy sector but also in construction. This study aims to contribute to the valorisation of Typha australis in the field of biocomposites. For this purpose, Typha fibres were used. The fibres were extracted manually using a plastic comb, then subdivided into three zones, namely the bottom, middle and top of the plant, and dried. The obtained fibres, were characterized physically by measuring density, water content and absorption coefficient, and morphologically by determining the morphology of the section of the fibres.In many ways, the physical property results concerning density showed an average of the three areas of 1.53 g/cm3 with a water content between 6 and 10% and an absorption coefficient showing two main absorption phases. Concerning the tomography results, we directly noticed the presence of fibre bundles and not of individual fibres due to the manual extraction method used. In conclusion, the obtained results confirma behaviour comparable to those of the most commonly used natural fibres, namely flax. Typha australis has a real potential as reinforcement in biocomposites.

Sewer sediment deposition prediction using a two-stage machine learning solution
Authors: Ribalta Gené Marc , Béjar Ramón , Mateu Carles , Corominas Lluís , Esbrí Oscar , Rubión Edgar
Published: April 2024

Sediment accumulation in the sewer is a source of cascading problems if left unattended and untreated, causing pipe failures, blockages, flooding, or odour problems. Good maintenance scheduling reduces dangerous incidents, but it also has financial and human costs. In this paper, we propose a predictive model to support the management of maintenance routines and reduce cost expenditure. The solution is based on an architecture composed of an autoencoder and a feedforward neural network that classifies the future sediment deposition. The autoencoder serves as a feature reduction component that receives the physical properties of a sewer section and reduces them into a smaller number of variables, which compress the most important information, reducing data uncertainty. Afterwards, the feedforward neural network receives this compressed information together with rain and maintenance data, using all of them to classify the sediment deposition in four thresholds: more than 5, 10, 15, and 20% sediment deposition. We use the architecture to train four different classification models, with the best score from the 5% threshold, being 82% accuracy, 70% precision, 76% specificity, and 88% sensitivity. By combining the classifications obtained with the four models, the solution delivers a final indicator that categorizes the deposited sediment into clearly defined ranges.

Authors: Zhang Haijia , Liu Jiahong , Mei Chao , Dong Lirong , Song Tianxu
Published: April 2024

Green computing is the current research hotspot; adapting the professional computing model to the low-power ARM architecture processor is a research trend. This article constructs a hydrological–hydrodynamic model by choosing SWMM and TELEMAC-2D as submodules, taking stormwater grates and inspection wells as water flow exchange nodes. The container technology was selected to couple the model on the ARM architecture processor, and the adapted coupling model is named the ARM hydrological–hydrodynamic model (AHM). To verify the reasonableness and accuracy of the model, taking the inner harbor of Macao Peninsula as the study area, a numerical simulation study on the evolution of waterlogging was carried out in various scenarios. The analysis showed that the maximum flow velocity was concentrated in the streets with low topography in the city center, and the areas of standing water were distributed in a point-like manner. Risk distribution maps during different storm recurrence periods were also constructed. Finally, the direct economic losses caused by Typhoon Mangkhut were calculated based on the model results and compared with the statistical values, with an error of only 2.3%, and the direct flooding losses in the inner harbor area under different rainfall scenarios were derived accordingly.

Published: April 2024

Purpose of research. Investigation of the relationship between the input and output characteristics of a fuzzy logic system based on the application of the area ratio method. The description of the specified method and the results obtained during modeling in a tabular processor is carried out using the means of illustrative presentation of information – visual programming.

Methods. To study the area ratio method, we considered a fuzzy logic model containing two input variables with three triangular membership functions and one output variable with five triangular membership functions. A database of fuzzy rules has been formed. The degrees of activation of the output terms were determined using the minimax rule of output L. Zadeh. The defuzzification of the values was carried out using a model based on the area ratio method.

Results. There are advantages of the area ratio method over traditional models, which consist in the ability to compensate for the main disadvantage - narrowing the defazzification interval. Using the proposed method, the possibility of using different numbers of variables on the input and output membership functions is studied. The results of experimental studies have shown that combining the parameters allows us to create a visual representation of the characteristics between the input and output variables.

Conclusion. This article describes the area ratio method, which allows us to visualize the relationship between input and output variables. There are the main results of numerical modeling reflecting the specifics of the method. The study was conducted through visual programming, which provides a number of advantages, such as improving the quality of the software product, ensuring a clear structuring of the task and accessibility to human perception.
Understanding the Impact of Communicating Uncertainty About COVID-19 in the News: Randomized Between-Subjects Factorial Experiment
Authors: Zhao Rui , Lu Xuerong , Yang Jiayi , Li Biao
Published: April 2024

Background

Whether and how the uncertainty about a public health crisis should be communicated to the general public have been important and yet unanswered questions arising over the past few years. As the most threatening contemporary public health crisis, the COVID-19 pandemic has renewed interest in these unresolved issues by both academic scholars and public health practitioners.

Objective

The aim of this study was to investigate the impact of communicating uncertainty about COVID-19–related threats and solutions on individuals’ risk perceptions and misinformation vulnerability, as well as the sequential impact of these effects on health information processing and preventative behavioral intentions.

Methods

A 2×2 (threat uncertainty [presence vs absence]×solution uncertainty [presence vs absence]) full-fractional between-subjects online experiment was conducted with 371 Chinese adults. Focusing on the discussion of whether the asymptomatic cases detected during the COVID-19 pandemic would further lead to an uncontrolled pandemic, news articles were manipulated in terms of whether the infectiousness of asymptomatic cases and the means to control the transmission are presented in terms of their certainty or uncertainty. Participants were randomly assigned to one of the four experimental conditions, being instructed to read one news article. After reading the news article assigned, participants were asked to respond to a series of questions to assess their cognitive and behavioral responses.

Results

Individuals were more susceptible to believing false COVID-19–related information when a certain threat and uncertain solution were framed in the news article. Moreover, individuals’ perceptions of crisis severity increased when exposed to news information containing uncertain solutions. Both misinformation vulnerability and perceived severity were positively associated with information processing. Information seeking was positively associated with protective behavioral intention, whereas information avoidance was negatively associated with protective behavioral intention.

Conclusions

Our findings imply that uncertainty, depending on its aspect, can be effectively communicated to the public during an emerging public health crisis. These results have theoretical and practical implications for health communicators and journalists. Given its limited influence on individuals’ cognitive and behavioral responses, uncertainty related to a health threat should be disseminated to meet the public’s expectation of information transparency. However, caution is advised when communicating uncertainty related to potential solutions, as this factor exhibited a mixed impact on individual responses during a crisis.
The Impact of Performance Expectancy, Workload, Risk, and Satisfaction on Trust in ChatGPT: Cross-Sectional Survey Analysis
Authors: Choudhury Avishek , Shamszare Hamid
Published: April 2024

Background

ChatGPT (OpenAI) is a powerful tool for a wide range of tasks, from entertainment and creativity to health care queries. There are potential risks and benefits associated with this technology. In the discourse concerning the deployment of ChatGPT and similar large language models, it is sensible to recommend their use primarily for tasks a human user can execute accurately. As we transition into the subsequent phase of ChatGPT deployment, establishing realistic performance expectations and understanding users’ perceptions of risk associated with its use are crucial in determining the successful integration of this artificial intelligence (AI) technology.

Objective

The aim of the study is to explore how perceived workload, satisfaction, performance expectancy, and risk-benefit perception influence users’ trust in ChatGPT.

Methods

A semistructured, web-based survey was conducted with 607 adults in the United States who actively use ChatGPT. The survey questions were adapted from constructs used in various models and theories such as the technology acceptance model, the theory of planned behavior, the unified theory of acceptance and use of technology, and research on trust and security in digital environments. To test our hypotheses and structural model, we used the partial least squares structural equation modeling method, a widely used approach for multivariate analysis.

Results

A total of 607 people responded to our survey. A significant portion of the participants held at least a high school diploma (n=204, 33.6%), and the majority had a bachelor’s degree (n=262, 43.1%). The primary motivations for participants to use ChatGPT were for acquiring information (n=219, 36.1%), amusement (n=203, 33.4%), and addressing problems (n=135, 22.2%). Some participants used it for health-related inquiries (n=44, 7.2%), while a few others (n=6, 1%) used it for miscellaneous activities such as brainstorming, grammar verification, and blog content creation. Our model explained 64.6% of the variance in trust. Our analysis indicated a significant relationship between (1) workload and satisfaction, (2) trust and satisfaction, (3) performance expectations and trust, and (4) risk-benefit perception and trust.

Conclusions

The findings underscore the importance of ensuring user-friendly design and functionality in AI-based applications to reduce workload and enhance user satisfaction, thereby increasing user trust. Future research should further explore the relationship between risk-benefit perception and trust in the context of AI chatbots.

Authors: Almasri Abdullah , El-Kour Tatyana Y , Silva Liliana , Abdulfattah Yousef
Published: April 2024

Background

The emergence of smartphones has sparked a transformation across multiple fields, with health care being one of the most notable due to the advent of mobile health (mHealth) apps. As mHealth apps have gained popularity, there is a need to understand their energy consumption patterns as an integral part of the evolving landscape of health care technologies.

Objective

This study aims to identify the key contributors to elevated energy consumption in mHealth apps and suggest methods for their optimization, addressing a significant void in our comprehension of the energy dynamics at play within mHealth apps.

Methods

Through quantitative comparative analysis of 10 prominent mHealth apps available on Android platforms within the United States, this study examined factors contributing to high energy consumption. The analysis included descriptive statistics, comparative analysis using ANOVA, and regression analysis to examine how certain factors impact energy use and consumption.

Results

Observed energy use variances in mHealth apps stemmed from user interactions, features, and underlying technology. Descriptive analysis revealed variability in app energy consumption (150-310 milliwatt-hours), highlighting the influence of user interaction and app complexity. ANOVA verified these findings, indicating the critical role of engagement and functionality. Regression modeling (energy consumption = β₀ + β₁ × notification frequency + β₂ × GPS use + β₃ × app complexity + ε), with statistically significant P values (notification frequency with a P value of .01, GPS use with a P value of .05, and app complexity with a P value of .03), further quantified these bases’ effects on energy use.

Conclusions

The observed differences in the energy consumption of dietary apps reaffirm the need for a multidisciplinary approach to bring together app developers, end users, and health care experts to foster improved energy conservation practice while achieving a balance between sustainable practice and user experience. More research is needed to better understand how to scale-up consumer engagement to achieve sustainable development goal 12 on responsible consumption and production.

Authors: Goldfarb Netali , Tal Noa , Cohen Idan-Chaim , Elyashar Aviad , Ellen Moriah E. , Rami Puzis , Cohen Odeya
Published: April 2024

BACKGROUND

Healthcare research is pivotal for developing new treatments, improving care quality, and discovering novel treatment methods. Engaging medical staff in research is key to the success of the studies and the staff’s professional development. While physicians often participate in research, nurses are less likely to be involved. The literature outlines barriers to nurses’ involvement in research, such as lack of time and support from colleagues, and suggests solutions like offering advanced career opportunities and stipends to enhance their participation. Organizing the knowledge gained from nurses’ participation in research is essential to more clearly understand the barriers to conducting and implementing research studies.

OBJECTIVE

This review aims to systematically identify and analyze barriers that hinder nurses from conducting research and implementing research findings, as well as the solutions suggested to these barriers.

METHODS

: In accordance with Systematic Review Protocols (PRISMA), our systematic review was conducted through a multistep procedure that integrated both manual processing and novel automated natural language processing tools. The initial steps involved conducting a preliminary literature review and performing strategic searches in PubMed, Web of Science, and SCOPUS using selected keywords. We vectorized the documents using Sentence-BERT and TF-IDF, then applied cosine similarity to filter 206 relevant articles from an initial pool of 26,627, guided by the results of the preliminary literature review. We used GPT-4 to identify and categorize barriers and solutions in nursing research, extract study details, and analyze the development of these barriers and solutions over time.

RESULTS

We identified 635 barriers to nursing research across ten categories, notably Education, Organizational Support, and Time Constraints. Furthermore, 489 solutions to these barriers were identified and grouped, focusing on critical improvement areas like Educational Initiatives, Organizational Support, and Evidence-Based Practice Implementation.

CONCLUSIONS

Nursing research is crucial for improving health outcomes. Our review identified barriers to nursing research, their suggested solutions, and explored the relationship between these barriers and solutions. Overcoming these barriers can significantly improve research quality and its implementation. Using natural language processing tools is a promising approach for conducting systematic reviews.

Authors: Tak Yae Won , Lee Jong Won , Kim Junetae , Lee Yura
Published: April 2024

BACKGROUND

Digital health care apps, including digital therapeutics, have the potential to increase accessibility and improve patient engagement by overcoming the limitations of traditional facility-based medical treatments. However, there are no established tools capable of quantitatively measuring long-term engagement at present.

OBJECTIVE

This study aimed to evaluate an existing engagement index (EI) in a commercial health management app for long-term use and compare it with a newly developed EI.

METHODS

Participants were recruited from cancer survivors enrolled in a randomized controlled trial that evaluated the impact of mobile health apps on recovery. Of these patients, 240 were included in the study and randomly assigned to the Noom app (Noom Inc). The newly developed EI was compared with the existing EI, and a long-term use analysis was conducted. Furthermore, the new EI was evaluated based on adapted measurements from the Web Matrix Visitor Index, focusing on click depth, recency, and loyalty indices.

RESULTS

The newly developed EI model outperformed the existing EI model in terms of predicting EI of a 6- to 9-month period based on the EI of a 3- to 6-month period. The existing model had a mean squared error of 0.096, a root mean squared error of 0.310, and an R2 of 0.053. Meanwhile, the newly developed EI models showed improved performance, with the best one achieving a mean squared error of 0.025, root mean squared error of 0.157, and R2 of 0.610. The existing EI exhibited significant associations: the click depth index (hazard ratio [HR] 0.49, 95% CI 0.29-0.84; P<.001) and loyalty index (HR 0.17, 95% CI 0.09-0.31; P<.001) were significantly associated with improved survival, whereas the recency index exhibited no significant association (HR 1.30, 95% CI 1.70-2.42; P=.41). Among the new EI models, the EI with a menu combination of menus available in the app’s free version yielded the most promising result. Furthermore, it exhibited significant associations with the loyalty index (HR 0.32, 95% CI 0.16-0.62; P<.001) and the recency index (HR 0.47, 95% CI 0.30-0.75; P<.001).

CONCLUSIONS

The newly developed EI model outperformed the existing model in terms of the prediction of long-term user engagement and compliance in a mobile health app context. We emphasized the importance of log data and suggested avenues for future research to address the subjectivity of the EI and incorporate a broader range of indices for comprehensive evaluation.

Emergency Management System Evaluation and Fiscal Policy Inspiration—Take Liaoning Province as an Example
Authors: Kang Qiao
Published: April 2024

Taking Liaoning province as an example, based on the evaluation of its emergency management system (EMS), this paper puts forward some suggestions on fiscal policy innovation in view of the main problems. Firstly, according to the hierarchical structure model, the evaluation system is established. The relative degree of the index is determined by the Delphi method, and the weight of the index at all levels is calculated. The evaluation factor set and evaluation grade set are constructed, and the EMS evaluation model of Liaoning province is established and evaluated by using fuzzy mathematics evaluation method. Secondly, according to the model evaluation results, four conclusions are obtained. The top three secondary indicators are Industrial Development, Policies Regulations and Fund Source, which are very important in EMS. The top three weights of the three-level indicators are the Development of Industry, Policy Formulation and Social Funds. Active fiscal policies should be formulated to use social funds to promote the development of emergency industries. Four of the second-level indicators have reached Good, and two have reached Average. Among them, the Basic Platform has the highest score, which is a positive result of EMS construction in Liaoning province. The final score of the comprehensive evaluation of the target is the low-end level in the Good grade, indicating that there is still much room for development in the construction of the system. Finally, according to the evaluation conclusion, this paper puts forward the fiscal policy innovation to support the development of EMS, including expanding the investment channels, updating the investment fund model, increasing the selection of policy tools and establishing the national emergency management fund.
Misconceptions Created by Tulodziecki’s Revisionist Account of Semmelweis’s Theory and Reasoning in the Philosophy of Science Literature
Authors: Kadar, M.D. Nicholas
Published: April 2024

Semmelweis’s work on the nature and cause of childbed fever has been used as a ‘paradigm case’ by philosophers of science “to illustrate aspects of the confirmation of theory by data” for more than fifty years (Scholl & Räz 2016). However, in 2013, Dana Tulodziecki challenged this paradigmatic view, and argued, based on a reconstruction of Semmelweis’s work that differed from “the standard story as it is found in the extant philosophical literature on Semmelweis”, that Semmelweis was “not the excellent reasoner he has been supposed to be.” Philosophers of science have accepted Tulodziecki’s reconstruction of Semmelweis work at face value as valid, and have already used it to question the philosophical theses Semmelweis work has been used to illustrate. The purpose of this article is to cut short this revisionist trend by demonstrating that, based on the Semmelweis’s own account of his theory and reasoning, and on other contemporaneous publications, Tuloziecki’s account of Semmelweis’s work is in every material respect incorrect and historically untenable.

Published: April 2024

Los efectos de la introducción de Amatitlania nigrofasciata sobre la ictiofauna nativa han sido poco explorados. El objetivo del presente estudio fue analizar la influencia del espacio y alimento como factores que expliquen la coexistencia de este cíclido con el nativo Herichthys pantostictus en la Reserva de la Biosfera Barranca de Metztitlán. Con la información procedente de recolectas y del monitoreo ambiental de 7 localidades visitadas entre marzo de 2016 y mayo de 2018, se determinaron el uso, selección y traslape de hábitat, mediante índices y métodos multivariados. Adicionalmente, se calculó el traslape de la dieta, con aquellos ejemplares que coincidieron espacial y temporalmente. Los resultados señalan que el uso y la selección diferencial del hábitat, en función de la cobertura de distintos sustratos y profundidades, se manifiesta en un bajo traslape espacial entre las especies, en contraste con el traslape de dieta que es muy alto. Así, el aprovechamiento diferencial del espacio permite explicar la coexistencia de estos cíclidos en la reserva. Esto último no necesariamente es una respuesta a las condiciones ambientales o a la utilización de determinados recursos, sino que puede ser resultado de interacciones de competencia relacionadas con la defensa de territorios de anidación o alimentación.

La leishmaniasis y la enfermedad de Chagas son causadas por protozoarios que comparten características filogenéticas y eco-epidemiológicas comunes, lo cual provoca dificultad en su identificación y diagnóstico. El objetivo de este trabajo fue analizar la información disponible sobre las técnicas de identificación de T. cruzi, de Leishmania spp. y la coinfección con ambos parásitos, así como su impacto en la obtención de datos eco-epidemiológicos. Se realizó una búsqueda sistemática de técnicas de identificación para T. cruzi, Leishmania spp. o ambos. Los estudios se clasificaron por agente etiológico, tipo de publicación, técnica utilizada y hospedero. Se realizó una prueba de X2 para evaluar la relación entre el parásito y la técnica utilizada. También se analizó la relación entre los trabajos publicados por año, la técnica diagnóstica y el parásito. De 138 trabajos analizados, se determinó que no existe un “estándar de oro” para el diagnóstico de estas parasitosis y la coinfección. Por tanto, se requiere la estandarización de protocolos que incrementen la sensibilidad y especificidad, así como el uso de al menos 2 técnicas en la identificación. Es imprescindible estudiar la prevalencia e incidencia de estas parasitosis en la fauna silvestre y la población humana bajo el contexto de cambio climático.
Vertical Electrical Sounding Technique as an Efficient and Rapid Tool for Groundwater Investigation in a Basaltic Environment at Kodana Station for the Shami goats. Case Study from Southern Syria
Authors: Asfahani Jamal
Published: April 2024

Geoelectrical survey was conducted by using vertical electrical sounding technique (VES) with adapting Schlumberger configuration, to locate and drill a borehole for groundwater extraction in the Kodana station for the Shami goats, Southern Syria. An integrated approach is proposed to increase the efficacy of the VES technique and to reduce the uncertainties and the high failures in locating and drilling a successful groundwater borehole. The approach is essentially based on analyzing the Dar-Zarrouk (D-Z) parameters with constraining several conditions to obtain the optimum hydro-geophysical model.The 1D inversion quantitative interpretation of twelve VES sounding points and the (D-Z) parameters allowed the characterization of the study area in terms of depth and the Neogene pyroclastic basalt aquifer. The result showed that VES point (V6) has the optimum and favorable properties for drilling a successful borehole in the area. The V6 has GPS coordinates of E: 3589614, N: 3301961 and Z: 770835m. The Neogene (fractured pyroclastic layer with rocks of basaltic composition) aquifer at this V6 point is characterized by a thickness (h) of 217m, a resistivity (ρ) of 227Ωm, a transverse resistance (R) of 49259 Ωm2, and an anisotropy parameter (λ) of 1.15. The advantages of the proposed approach are well proven and documented, in comparing with other techniques that require the combination of VES technique with other available geophysical techniques. The VES technique within the proposed approach is therefore recommended to be easily applied for groundwater investigations, and locating the suitable positions for drilling boreholes in similar worldwide basaltic environments.
Site effect evaluation for Culiacan, Sinaloa, Mexico

Published: April 2024

Using the spectral ratio technique (HVSR), we performed an analysis of 120 seismic noise records obtained at different points distributed throughout the city of Culiacán, Sinaloa, México. The results show a clear relationship of dominant periods between 0.2 to 0.7 for the alluvium zone in the central and western area of the city and minor periods for points near outcrops of igneous rocks south and southeast of the city. The higher relative amplitudes were found along the riverbed, in the transition zone of conglomerate deposits to alluvium. We performed a multichannel analysis (station arrays) at some points in which we also measured H/V. Afterward, we produced velocity profiles were obtained and transfer functions were calculated. Five of these values were compared with the HVSR technique. Three of them could be compared with the surficial startigraphy obtained in soil mechanics studies to which access was granted.
Investigation of Salanda Fault Zone, between Yesiloz and Gumuskent (Nevsehir-Turkey) with PSInSAR
Authors: Demircioğlu Ramazan , Oktar Osman
Published: April 2024

In this study, the section of the Salanda fault zone between Yesiloz village and Gumuskent (Nevsehir, Turkey) was investigated by geodetic methods, and the amount of movement in this area was determined. We used a Persistent Scatterer Interferometric Synthetic Aperture Radar (PSInSAR) to determine the line of sight (LOS) movement. Previous studies using geological and geomorphological indices have shown that the Salanda fault zone is active. For the first time in this study, 36 synthetic aperture radar (SAR) images acquired between January 8, 2020, and November 29, 2022, were used in PSInSAR analysis. When the annual velocity values of the stud area in the LOS direction were analysed, annual subsidence values of up to 7.6 mm and annual uplift values of up to 7.2 mm were revealed. These movements indicate that the Salanda fault is active and normal fault characteristics. However, it also has a dextral strike-slip component.

Published: April 2024

In the Michoacán region of central-western Mexico, the village of Turícuaro has for centuries been a center for metate production based on andesites exploited on the slopes of Hoya Urutzen and 'El Metate' volcanoes. Surveys have been conducted in this volcanic landscape, with the invaluable help of one of the last metateros (craftsmen) family of the village, the Vidalès, in order to reconstruct the strategies adopted through time to extract this andesite over a large territory. It has been possible to propose a first mapping as well as a relative dating of the various quarrying areas. Different types of exploitations have been described, from ancient quarries, associated with archaeological occupations, to current extraction sites. The morphology of the outcrops (walls, isolated blocks) partly conditioned the organization of the quarries (flat, organized on terraces, etc). It has also been possible to observe the different strategies and organization of work associated with this activity, through the observation of the abandoned blocks, waste and roughouts. Finally, this work offers a new perspective on Mesoamerican metate quarrying strategies.
Usos de la imagen en los impresos novohispanos dentro de la Congregación de San Felipe Neri
Authors: Garone Gravier Marina , González León Erika B.
Published: April 2024

Los libros impresos y manuscritos realizados por la Congregación del Oratorio de San Felipe Neri son testimonio cultural de su época y del grupo religioso que los consumía. La investigación de las imágenes de esos impresos se organiza en una mención de elementos esenciales para el estudio de la imagen en el libro antiguo; un breve contexto histórico del Oratorio, y la ubicación de dos momentos de la producción editorial de la Congregación, a partir del repertorio de impresos localizados en la Biblioteca Nacional de México. Se analizarán la imagen ornamental (específicamente los casos de la imagen comodín, la que se aplica como ajuste de composición tipográfica y un ejemplo particular de uso de marca tipográfica), así como las imágenes narrativas.
En defensa de La Revolución de Fabián Cháirez
Authors: Soto Rodríguez Mario Andrés
Published: April 2024

Este artículo aborda la obra La Revolución del pintor mexicano Fabián Cháirez y su recepción por parte del público, a la luz de los acontecimientos que marcaron su exposición en el Museo del Palacio de Bellas Artes de la Ciudad de México, a principios de 2020. El análisis realizado se enfoca en los ataques y las defensas que se esgrimieron sobre la obra y el artista, tomando como punto de referencia las tres defensas del arte contemporáneo propuestas por Anthony Julius: la canónica, la formalista y la del alejamiento. Se concluye que la transgresión ofrecida por el artista posibilita una renovación del personaje de Emiliano Zapata, ya que el cuadro funge como pieza de resistencia queer al cuestionar los imaginarios de la masculinidad hegemónica. La obra en cuestión implica una reapropiación, resignificación y una teatralización de la figura del “Caudillo del Sur”.
Sistematización de la propuesta infraleve de Marcel Duchamp como categoría estética
Authors: De la Torre Llorente Elisa
Published: April 2024

Análisis del poco difundido concepto infraleve, propuesto de manera críptica por Duchamp desde 1914 como aquellas observaciones particulares de la vida anotadas en un cuaderno y que, conectadas por un nexo ambiguo, agrupó bajo este término, dejando a la libre interpretación del lector la descodificación de su contenido. Fruto de un largo camino conceptual que desemboca en la negación de lo visual, lo infraleve recoge múltiples y variadas acepciones y supone, por ello, un concepto bastante difícil de explicar y definir por lo complejo de su significado. La propuesta de esta investigación sintetiza a diferentes autores conocedores de la obra de Duchamp, y concluye  que la relación de significación entre todas sus acepciones guarda un sentido metafísico en torno a la contingencia de la realidad. Por último, se propone una sistematización que se ajusta a todas sus posibles variantes para su mayor comprensión y posible aplicación como categoría estética artística.
