Popular Catholicism Puerto Rican Style: The Virgin of Rincón, Human Agency, and Miracles
Authors: Santiago-Vendrell Angel D.
Published: April 2024

In the past, popular Catholicism in Latin America and the Caribbean was perceived with suspicion by liberation theologians and official Roman Catholicism for its eccentricities, lack of doctrinal coherence, and fears of syncretism with folk religions. Nowadays, popular Catholicism in Latin America and the Caribbean has been a source of theological reflection, ecumenism, and religious revitalization. The apparition of the Holy Mother in 1953 at barrio Rincón in Sabana Grande, Puerto Rico, is a case study in global Catholicism that exemplifies this turn to see popular Catholicism as a source of liberation, perseverance, and deep spiritual devotion by the faithful. Using cultural, social, and reception historiography, the article argues that the Puerto Rican faithful were not passive recipients of the literary narratives of journalists covering the events as narrated by the main protagonists, the children/seers, but rather themselves formulators of history through their reception and participation. This is demonstrated by the allegiances of the faithful to popular Catholicism and their rejection of the official mandates of the clergy to ignore the events taking place at barrio Rincón regarding the apparition of the Virgin.

Artisanal and Small-scale Gold Mining (ASGM) is a source of supply in many areas of the world, especially in developing countries. This is often carried out illegally using toxic substances such as mercury. Mercury, due to its chemical–physical properties and the transport factors involved between the different environmental matrices, can percolate through soil and from surface water to groundwater. The objective of this study was to conduct a human health risk assessment. For this purpose, a screening of mercury concentrations was carried out, collecting 67 water samples at selected points, and a risk assessment was performed applying both a deterministic and a probabilistic approach. A deterministic approach is a specific analysis based on determining the values of the risk quotient (HQ) and the risk index (HI) for each receptor category (adults and children) and scenario (residential and recreational) considered; a probabilistic approach is based on stochastic simulation techniques and the evaluation of the statistical quantities. There was found to be a discrepancy between the results provided by the two approaches, with the deterministic approach suggesting a more worrisome picture. However, in general, the results showed a greater exposure in the provinces of El Oro and Esmeraldas, and a greater vulnerability of child receptors.

The Bailong River Basin is one of the most developed regions for debris flow disasters worldwide, often causing severe secondary disasters by blocking rivers. Therefore, the early identification of potential debris flow disasters that may block the river in this region is of great significance for disaster risk prevention and reduction. However, it is quite challenging to identify potential debris flow disasters that may block rivers at a regional scale, as conducting numerical simulations for each debris flow catchment would require significant time and financial resources. The purpose of this article is to use public resource data and machine learning methods to establish a relationship model between debris flow-induced river blockage and key influencing factors, thereby economically predicting potential areas at risk for debris flow-induced river blockage disasters. Based on the field investigation, data collection, and remote sensing interpretation, this study selected 12 parameters, including the basin area, basin height difference, relief ratio, circularity ratio, landslide density, fault density, lithology index, annual average frequency of daily rainfall exceeding 40 mm, river width, river discharge, river gradient, and confluence angle, as critical factors to determine whether debris flows will cause river blockages. A relationship model between debris flow-induced river blockage and influencing factors was constructed based on machine learning algorithms. Several machine learning algorithms were compared, and the XGB model performed the best, with a prediction accuracy of 0.881 and an area under the ROC curve of 0.926. This study found that the river width is the determining factor for debris flow blocking rivers, followed by the annual average frequency of daily rainfall exceeding 40 mm, basin height difference, circularity ratio, basin area, and river discharge. The early identification method proposed in this study for river blockage disasters caused by debris flows can provide a reference for the quantitative assessment and pre-disaster prevention of debris flow-induced river blockage chain risks in similar high-mountain gorge areas.

Published: April 2024

Measurement of lightning current plays a critical role in the field of atmospheric electricity. Traditionally, Rogowski coils or low-resistance shunts were employed for measuring lightning currents in the range from several amperes up to several hundreds of kilo-amperes, and high-value resistors were utilized for measuring corona discharge currents at sub-ampere levels. However, these approaches were not suitable for continuously recording the vast range of lightning currents. For this sake, we have developed a lightning current measurement system equipped with a shock-tolerant low-noise amplifier module. With the system installed on a tall tower, sub-ampere level currents just before the lightning initiation were observed for the first time. To confirm the authenticity of the recorded currents, the background noise of the measurement system and surrounding environment were identified, and a digital multi-frequency notch filter was proposed for de-noising. Results show that the system can achieve a current identification level of 50 mA even in complex electromagnetic environments, while having a measurement capability of 220 kA.

Published: April 2024

Soil organic carbon stock (SOCS) changes caused by land use changes are still unclear, and understanding this response is essential for many environmental policies and land management practices. In this study, we investigated the temporal–spatial and vertical distribution characteristics of the SOCS in the Western Sichuan Plateau (WSP) using the sparrow search algorithm–random forest regression (SSA-RFR) models with excellent model applicability and accuracy. The temporal–spatial variations in the SOCS were modeled using 1080 soil samples and a set of nine environmental covariates. We analyzed the effect of land use changes on the SOCS in the WSP. The total SOCS increased by 18.03 Tg C from 1990 to 2020. The results of this study confirmed a significant increase in the SOCS in the study area since 2010. There was a 27.88 Tg C increase in the SOCS in 2020 compared to the total SOCS in 2010. We found that the spatial distribution of the SOCS increased from southeast to northwest, and the vertical distribution of the SOCS in the study area decreased with increasing soil depth. Forests and grasslands are the main sources of SOCS the total SOCS in the forest and grassland accounted for 37.53 and 59.39% of the total soil organic carbon (SOC) pool in 2020, respectively. The expansion of the wetlands, forest, and grassland areas could increase the SOCS in the study area. A timely and accurate understanding of the dynamics of SOC is crucial for developing effective land management strategies to enhance carbon sequestration and mitigate land degradation.

Published: April 2024

The eco-agricultural park is a new comprehensive agricultural technology system integrating agricultural production, rural economic development, ecological environment protection, and efficient resource utilization. Therefore, an in-depth analysis of the ecosystem structure of eco-agricultural parks will help achieve the goal of coordinated symbiosis between human development and environmental protection. This study takes the research area of the Eco-agricultural Park of Jinchuan Town, Huinan County, a typical town in the Changbai Mountains of Northeast China. Based on field surveys, market research, farmer consultation, and related data collection, emergy theory and methods are used to construct an emergy model for the park. The value evaluation index system integrates the unique emergy index of the agricultural ecosystem with the traditional emergy index system to conduct a targeted evaluation of the park’s functional structure and sustainable development capabilities in order to improve the efficiency of material and energy use and provide technical reference for ecological construction and comprehensive development of agricultural industry in mountainous areas in northern China. The research results show that: (1) The annual input total emergy of the eco-agricultural park is 4.04E+24 sej/a, and the emergy of labor input, electricity input, and topsoil loss is relatively high. The park is in a labor-intensive stage. The annual output total emergy is 5.09E+24 sej/a, the park is dominated by planting and forestry industries. (2) The park’s emergy utilization intensity is high—production efficiency is high, economic development is advanced, and the system’s self-control, adjustment, and feedback functions are vital—and plays a significant role in promoting the development of the regional economy. However, the park relies more on investment from external resources, and production in the park puts pressure on the environment. (3) The current sustainable development capability of the study area is weak, and the factors affecting the sustainable development capability are mainly energy loss and uneven distribution of industrial areas in the park. Effective measures to promote the transformation of the park to develop technology-intensive industries and improve the sustainable development performance of the park were proposed. These include: adjusting the proportion of industries in the park; reducing high-energy external input emergy, such as industrial auxiliary emergy; reducing the loss of non-renewable natural resources through ecological engineering measures, such as reducing the depth of slope runoff in the park; and combining modern resource-based production technology and environmentally sound management methods to reduce energy loss and rational use of natural resources.

Authors: Hong Hua , Sun Lili , Zhao Lijuan
Published: April 2024

Carbon emissions from agriculture should not be underestimated. With the aim for carbon peaking and carbon neutralization and the help of digital inclusive finance, the effective reduction in carbon emissions in agriculture and animal husbandry production is crucial to achieving China’s carbon emission reduction goals. We used the balanced panel data of 31 provinces in China from 2011 to 2021 to study this issue. We empirically tested the impact, mechanism, and heterogeneity of digital inclusive finance on agricultural carbon emissions based on the systematic measurement of agricultural carbon emissions. The results revealed that (1) the development of digital inclusive finance has a significant inhibitory effect on agricultural carbon emissions, and it is an important path to reduce agricultural carbon emissions. (2) Through the intermediary effects’ analysis, it was found that capital deepening is an important transmission mechanism for the promotion of agricultural carbon emission reduction through digital inclusive finance. (3) Further analysis using the quantile regression model reveals that the impact of digital inclusive finance on agricultural carbon emissions is significantly negative at different quantiles. (4) Through the spatial Durbin model, digital inclusive finance has a space carbon enhancement effect. Finally, we put forward suggestions to promote the development of low-carbon agriculture by paying attention to the technical effect of digital inclusive finance, strengthening the connection and cooperation between various regions and promoting the carbon emission reduction role of capital deepening.

Published: April 2024

As China continues to introduce policies to promote the construction of smart cities, the governance capacity and living environment of many pilot regions have moved towards smart development and sustainability. In order to reveal the impact of improving regional smart development on the lives of the elderly, we explored the relationship between regional smart development and the risk of poverty in old age. The results show that at present, the development of smart cities continues to grow; the majority of elderly respondents’ poverty risk is general; the development of smart cities at the regional level is effective in reducing the poverty risk of the elderly in the region, with the degree of impact varying by region; and the impact of smart development at the regional level on the risk of poverty in old age varies with different levels of social support. Based on this, suggestions are made to vigorously develop the regional economy, improve the social security mechanism for the elderly, and accelerate the digitalization and humanization of infrastructure so as to better meet the needs of China’s elderly population in the context of high-quality smart development in the region and achieve sustainable development goals.

Authors: Builes-Vélez Ana Elena , Escobar Lina María , Villamil-Mejia Claudia
Published: April 2024

Creative and innovation districts are focused on boosting local economies. However, they also pay attention to the global scale since this local identity of the Orange Economies gives them added value and competitiveness globally, as well as international projection and visibility of products, services, and new technologies associated with creativity and innovation. Thus, this study reviews three case studies of the cities of Barranquilla, Bogota, and Medellin in Colombia, seeking to characterize the creative and innovation districts. The methodology used is strictly qualitative, resorting to the characterization of the polygons and the analysis of public policies. This study describes the general aspects of creative and innovation districts in Colombia. Then, it identifies the forces for CD and ID development in three Colombian cities and the drivers for urban sustainable transformation. The main purpose of this study is to understand if innovation and creative districts are new scenarios for sustainable urban planning.

Published: April 2024

Understanding the subsurface is of prime importance for many geological and hydrogeological applications. Geophysical methods offer an economical alternative for investigating the subsurface compared to costly borehole investigations. However, geophysical results are commonly obtained through deterministic inversion of data whose solution is non-unique. Alternatively, stochastic inversions investigate the full uncertainty range of the obtained models, yet are computationally more expensive. In this research, we investigate the robustness of the recently introduced Bayesian evidential learning in one dimension (BEL1D) for the stochastic inversion of time-domain electromagnetic data (TDEM). First, we analyse the impact of the accuracy of the numerical forward solver on the posterior distribution, and derive a compromise between accuracy and computational time. We also introduce a threshold-rejection method based on the data misfit after the first iteration, circumventing the need for further BEL1D iterations. Moreover, we analyse the impact of the prior-model space on the results. We apply the new BEL1D with a threshold approach on field data collected in the Luy River catchment (Vietnam) to delineate saltwater intrusions. Our results show that the proper selection of time and space discretization is essential for limiting the computational cost while maintaining the accuracy of the posterior estimation. The selection of the prior distribution has a direct impact on fitting the observed data and is crucial for a realistic uncertainty quantification. The application of BEL1D for stochastic TDEM inversion is an efficient approach, as it allows us to estimate the uncertainty at a limited cost.
Hydropower Politics in Northeast India: Dam Development Contestations, Electoral Politics and Power Reconfigurations in Sikkim

Published: April 2024

Around the world, the development of large dams has been increasingly contested. India is no exception and has seen the mobilisation of powerful domestic and transnational socio-environmental movements against dams over more than four decades. In this context, the State of Sikkim in northeast India has been entangled in prolonged hydropower development conflicts since the late 1990s. This article analyses these conflictive entanglements between the Government of India, the State Government of Sikkim, power companies and Sikkim’s autochthonous tribe, the Lepchas. It zooms in on the period of 2011–2017, which saw an abrupt escalation of the conflicts to analyse the messy, deeply political and often unpredictable and contradictory world of dam construction and its contestations. Our analysis is informed by the power cube framework developed by John Gaventa. Our analysis shows how hydropower development is deeply intertwined with local patronage relationships. We show how local elections bring out dam conflict and the operation of power into the open, sometimes leading to abrupt and unexpected switches in positions in relation to hydropower development. We show that these switches should be seen not only as “strategic electoral tactics” but also and importantly as contentious political struggles that (re)configure power in the region. We show how in this process, powerful political actors continuously seek to stabilise power relations among the governing and the governed, choreographing a specific socio-hydraulic order that stretches way beyond simple pro- and anti-dam actors and coalitions as it is embedded in deep hydro(-electro) politics and power plays.
Application and Research of Microseismic Monitoring System and Hydraulic Fracturing Technology in Coal Mines
Authors: Sun Hui , He Na , Gurkalo Filip
Published: April 2024

In order to improve the effectiveness of coal mine gas control and enhance the level of coal mine safety production, the application of a microseismic monitoring system and hydraulic fracturing technology in coal mines was studied. Applying hydraulic fracturing technology to coal mine gas treatment, firstly, the geological structure and gas concentration in the mining area are detected using the radio tunnel perspective method and infrared differential absorption method. Then, the relevant parameters of hydraulic fracturing are determined, and finally, hydraulic fracturing technology is implemented. Microseismic monitoring technology is used to monitor the cracks formed during hydraulic fracturing construction and evaluate the fracturing effect. The instantaneous energy envelope is obtained from the microseismic data of each detection channel after stacking and Hilbert transform static correction. A microseismic in-phase inversion positioning objective function based on travel time residuals is constructed, and under the constraints of polarization analysis, the optimal solution is obtained through search iteration to complete microseismic in-phase inversion positioning. Experimental results have shown that after applying this method to coal mine gas control, the gas concentration decreases below the execution standard, achieving good control effects. Under microseismic monitoring in coal mines, the hydraulic fracturing effect can be effectively and reasonably evaluated, and the safety production level of coal mines can be improved.

Published: April 2024

The process of estimating sediment load has been a daunting issue in hydraulics and the water resource field. Several methods exist for predicting the sediment load in a catchment or river, but the majority of these methods are empirical and depend on the specific location where they are used. Understanding the underlying mechanism of sediment generation and its transport in connection with precipitation, topography, and subsurface conditions to characterize its process is helpful for determining the sediment load in a river. For this purpose, we analyzed the daily suspended sediment data measured for 8 years at the headworks of the Kabeli A hydropower project in the Kabeli River, which originates from the Himalayan region. The analyses show that the suspended sediment concentration (SSC) varies in an orderly manner over time and asynchronously between seasons with respect to the river discharge. Clockwise hysteresis is observed in the yearly plots between the SSC and river discharge. The hysteresis becomes narrower when compared with the direct runoff obtained from a digital filtering algorithm and, even more so with the direct runoff from the hydrological model SWAT. The analysis shows that the sediment concentration is controlled not only by the total discharge in the river but also by the contribution of ground water to the river discharge, indicating that the total discharge alone cannot reflect the seasonal variation in SSC. It is inferred that the river is supply-limited and the hillslope is transport-limited with respect to sediment sources. The SWAT model suggests that the base flow contribution to the total river discharge is 78%. Here, we present a method for constructing the suspended sediment rating curve by comparing the direct runoff with the sediment concentration. The deduced sediment rating curve captures 84.51% of the total sediment load over the study period in the Kabeli River. This method may potentially be used in similar catchments with supply-limited rivers and transport-limited hillslopes.

Published: April 2024

Ecological water diversion is an important method to improve water quality in lakes and reservoirs. But the environmental effects, from the ecological water diversion project (EWDP) to the internal release of sediment nutrients, remain unclear. In this study, an indoor simulation of an EWDP with different treatment scenarios with water transfer proportions of 25%, 50%, 75% and 100% was conducted to study the effects of water diversion on sediment nitrogen and phosphorus release in Lake Wanshandang. Our results showed that the flux of NH3–N released from the sediments in the western and eastern areas of Lake Wanshandang was significantly reduced after water transfer treatment, and the degree of reduction increased with increased water transfer. Specifically, the release flux of NH3–N in the sediment in the western area decreased from 18.02 mg/(m2/d) to −2.25 mg/(m2/d) when the transferred water reached 100% replacement of the original overlying water. The effect of water transfer treatment on the release flux of SRP from sediment varied greatly throughout the lake. After treatment, the SRP release flux in the western and central areas increased significantly, while it decreased in the eastern area. The NH3–N and SRP concentrations changed from 0.12–0.27 mg/L and 0.02–0.049 mg/L to 0.28–0.84 mg/L and 0.01–0.066 mg/L before and after the water transfer treatment. Our statistical analysis showed that the change in NH3–N and SRP release fluxes after treatment was significantly negatively correlated (p < 0.05) with concentrations of NH3–N or SRP in the overlying water before and after water transfer. We suggest the increase in NH3–N and SRP concentrations in the overlying water after the water transfer treatment led to the subsequent decreased NH3–N or SRP release flux, while the decrease in SRP concentration in overlying waters enhanced SRP release from the sediment. The differences in the concentrations of nitrogen and phosphorus between the original overlying water and the transferred incoming water are important factors affecting the release of nutrients from sediment.

Published: April 2024

With more electric vehicles introduced in society, there is a need for the further implementation of charging infrastructure. Innovation in electromobility may result in new charging and discharging strategies, including concepts such as smart charging and vehicle-to-grid. This article provides an overview of vehicle charging and discharging innovations with a cable connection. A MATLAB/Simulink model is developed to show the difference between an electric vehicle with and without the vehicle-to-grid capabilities for electricity grid prices estimated for Sweden for three different electric vehicle user profiles and four different electric vehicle models. The result includes the state-of-charge values and price estimations for the different vehicles charged with or without a bidirectional power flow to and from the electric grid. The results show that there is a greater difference in state-of-charge values over the day investigated for the electric vehicles with vehicle-to-grid capabilities than for vehicles without vehicle-to-grid capabilities. The results indicate potential economic revenues from using vehicle-to-grid if there is a significant variation in electricity prices during different hours. Therefore, the vehicle owner can potentially receive money from selling electricity to the grid while also supporting the electric grid. The study provides insights into utilizing vehicle-to-grid in society and taking steps towards its implementation.

Published: April 2024

Agrochemicals are used extensively in agriculture sector across the world; however, they may be eco-toxicological hazards and disrupt the non-target living beings, including birds. Hence, the present study was carried out to evaluate the toxic effects of chlorpyrifos (CPF) insecticide on hematological parameters in pigeons. A total of 120 adult pigeons (Columba livia domestica) were used in the study and kept in wooden cages, and all pigeons received the same quantity of (22%) crude protein and water during trials. Pigeons were acclimatized for 15 days and divided into four equal (A, B, C and D) groups, each consisting of 30 birds. Test groups (B-D) were exposed to CPF with oral doses of “1.3 mg, 1.6 mg, and 2.1 mg/kg body weight/day” respectively for twelve successive weeks, whereas (group A) was assigned as a controlled group. At the end of the trials, blood samples from exposed and controlled group birds were obtained from brachial and collected with anticoagulant “K3-EDTA” vacutainer tubes for hematological assessments. Following the 84-day exposure period, notable statistically significant (p < 0.05) reduced levels of hemoglobin (Hb) (13.85 g/dl), (12.2 g/dl) and (10.50 g/dl) respectively, in birds of groups B, C and D and significant (p < 0.05) reduced level of total erythrocytes count (TEC) and packed cell volume (PCV%) was noted when compared with the control. There was a substantial significant (p < 0.05) increase in total leucocyte count (TLC) and total platelet count observed in comparison to the birds of the control group. The results of the present study revealed that alterations in hematological indices exhibited by chlorpyrifos insecticide. This research demonstrated how the indiscriminate use of pesticides damages health and developmental problems in bird ecosystems, and eventually, humans may be in danger for their health problems

Intense terahertz (THz) radiation in free space has immense potential for regulating material state, accelerating electrons, producing biological effects, and so on. However, the high cost and challenges involved in constructing strong-field THz sources have limited their developments, making it difficult for the potential applications of strong-field THz radiation to be widely adopted. Spintronic THz emitters (STEs) with numerous merits such as high efficiency, ultrabroadband, ease of integration, and low cost have become ubiquitous, but the majority of these emitters require stable operation in the presence of external magnets, limiting their applications, particularly in generating strong fields that necessitate large-sized samples. Here, we demonstrate the feasibility of generating strong-field THz radiation in 4-inch antiferromagnetic material–ferromagnetic metal (IrMn

[2 nm]/Co
20
Fe

B
20
[2 nm]/W [2 nm]) without external magnetic field driving. Under the excitation of a Ti:sapphire femtosecond laser amplifier with a 35-fs pulse duration and a 1-kHz repetition rate, we obtain strong-field THz radiation from our STEs with a pulse duration of ~110 fs, and a spectrum covering up to ~10 THz. Further scaling up the pump laser energy up to 55 mJ with a pulse duration of ~20 fs and a repetition rate of 100 Hz provided by the Synergetic Extreme Condition User Facility, the radiated THz electric field strength from the external-magnetic-free 4-inch STEs can exceed 242 kV/cm with a pulse duration of ~230 fs, a spectrum covering up to ~14 THz, and a single pulse energy of 8.6 nJ measured by a calibrated pyroelectric detector. Our demonstrated external-magnetic-field-free high-field STEs have some unique applications such as producing sub-cycle ultrashort strong THz fields in huge size emitters under the excitation of high-energy light sources, accelerating the development of THz science and applications.
Investigating the Status of Contamination With Pulex irritans and Xenopsylla cheopis in Pets, Guard and Stray Dogs in Tabriz, Iran
Authors: Shabestari Asl Ali , Garedaghi Yagoob , Motameni Pouya
Published: April 2024

Introduction: Fleas are the most prevalent ectoparasites indoors and outdoors due to their high reproductive rate, ability to feed on different hosts, and the unpleasant effects of their bites. Methods: This study was conducted on 360 dogs in and around Tabriz to find the rate and type of human flea contamination in these dogs, which were divided into three categories: pets, guards, and stray dogs. After fleas were identified in the dogs’ skin, they were taken with glue and fixed on the slide with glue. When the number of fleas was large, the captured fleas were transported to a test tube and treated with 70% alcohol. Dehydration of fleas was performed with ascending percentages of ethanol from 50 to 100% absolute and was kept inside each alcohol percentage for 10 to 20 minutes. Results: Regarding the dogs studied in this research, the rate of actual contamination in guard dogs was 76.67% (92 dogs were contaminated with flea feces). However, 74 dogs (about 15%) were infested with different fleas. Unfortunately, the rate of contamination in stray dogs was 100%. The rate of real contamination based on the separation of fleas and flea excrement from the body of this group of dogs was equal. The rate of flea infestation in pet dogs was 14 out of 100 dogs, representing 14% contamination. Conclusion: It should be acknowledged that, unfortunately, flea infestation is expected in the region’s dogs, depending on the type of dogs kept. Infestation with these insidious skin parasites with varying rates and symptoms is common, which, in addition to the economic damage of spending time and money on medicine for disease in animals, causes environmental pollution, increases the likelihood of disease transmission by these parasites, and increases the possibility of human infection and disease transmission from them to humans, as well as environmental pollution.

El deporte olímpico como material de la cultura: Tokio 2020+1 desde la comunicación
Authors:   , Paiva Juan Bautista
Published: April 2024

Esta es una tesis que identifica y analiza las formas novedosas en que se expresaron problemáticas culturales, sociopolíticas y geopolíticas en los Juegos Olímpicos de Tokio 2020+1 para rastrear cómo estas tensiones convergen en un umbral histórico para el deporte y la sociedad en el marco de transformaciones ocurridas en la cultura durante la pandemia a causa de la propagación del COVID-19. Asimismo, indaga cómo en el deporte de los Juegos Olímpicos se nos presentan visiones del mundo en torno al género, la salud mental, las corporalidades y los conflictos geopolíticos de cada una de las épocas. De esta manera, se propuso considerar al evento como un material de la cultura cargado de historia y a las y los atletas que participan como una vía para observar proyecciones sociopolíticas y culturales. A partir de estas problematizaciones se buscó construir un análisis crítico en torno a la experiencia acontecida durante la pandemia, entendiendo que fue un período histórico signado por la lesión de las estatalidades y la intensificación de las violencias y las desigualdades materiales y simbólicas en todo el mundo. En este sentido, los Juegos Olímpicos de Tokio 2020+1 fueron utilizados como un motivo desde donde hacer un cúmulo de interrogantes a la escena del presente durante el tiempo de la pandemia. La pregunta sobre la experiencia ocurrida en los tiempos de la pandemia implica adentrarse en un período bisagra, un determinado espacio temporal donde se alteraron las experiencias del mundo, las costumbres, las instituciones, perdiendo vigencia el pasado. La pregunta por los Juegos Olímpicos de Tokio 2020+1 es un interrogante por el tiempo histórico, por la relación entre historia y tiempo, que significa una confrontación entre pasado y futuro, entre la experiencia y la expectativa, donde se articula el tiempo pretérito y lo que vendrá. Los Juegos Olímpicos tienen la particularidad de ser la competencia deportiva que reúne a la mayor variedad de deportes y atletas del mundo. Por lo tanto, el ejercicio de realizar una investigación sobre este acontecimiento, que posee una escala universal, implica analizar sus dimensiones políticas, económicas y sociales teniendo en cuenta que es un espacio donde se disputan diferentes intereses que no se agotan en lo estrictamente disciplinar.
A Review of Automatic Item Generation Techniques Leveraging Large Language Models

Published: April 2024

Over a decade ago, automatic item generation (AIG) was introduced to meet the increasing need for high-quality items in educational measurement. Around the same time, a new area of research in computer science began to develop questions for educational use. Historically, researchers from these two domains had little knowledge or communication with one another. However, the development of pre-trained large language models (LLMs) has sparked the interest of researchers from both domains in applying these models for automatically creating items. With similar objectives and methodologies, these two research domains appear to be converging on how to address the problems in this field. The purpose of this study is to provide a review of the current state of research by synthesizing existing studies on the use of LLMs for AIG. By combining research from both domains, we examine the utility and potential of LLMs for AIG. We performed a comprehensive literature review in seven research databases, selected studies based on predefined criteria, and summarized 60 relevant studies that employed LLMs in the AIG process. We identified the most commonly used LLMs in current AIG literature, their specific applications in the AIG process, and the characteristics of the generated items. We found that LLMs are flexible and effective in generating various types of items based on different languages and subject domains. However, many studies have overlooked the quality of the generated items, indicating a lack of a solid educational foundation. This review emphasizes the urgent need for greater integration of learning and measurement theories in future AIG research. We share two suggestions to enhance the educational foundation for leveraging LLMs in AIG, advocating for interdisciplinary collaborations to exploit the utility and potential of LLMs.

The primary objective of this research article is to identify the key impacts of integrating technology into public secondary schools in Makueni County. To achieve this, a descriptive research strategy has been employed, that brought in 140 teachers and 25 principals. Data collection was conducted via interview schedules and questionnaires that were aimed at administrators and teachers. The gathered data underwent quantitative and qualitative analysis. Descriptive statistics and mean calculations, a measure of central tendency, were utilized for data analysis. The research hypothesizes that Information and Communication Technology (ICT) plays a crucial role in enhancing educational quality. ICT enables more personalized instruction and immediate feedback, thereby improving literacy both inside and outside the classroom. The research article also examines how ICT can be used to foster creativity and higher-order thinking skills. In terms of administration, ICT is pivotal in streamlining tasks such as data collection, document processing, record-keeping, and financial document recovery, making retrieval more straightforward and administration more efficient. Furthermore, ICT aids in the efficient scheduling of school activities, including parents and teachers association (PTA) and Board of Management meetings, and managing school calendar events, classes, and exams. In a nutshell, the research article highlights the importance of ICT in disseminating information and fostering effective communication among stakeholders.
