Thermal and Optical Analyses of a Hybrid Solar Photovoltaic/Thermal (PV/T) Collector with Asymmetric Reflector: Numerical Modeling and Validation with Experimental Results
Authors: Korres Dimitrios N. , Papingiotis Theodoros , Koronaki Irene , Tzivanidis Christos
Published: June 2023

This study presents a combined thermal and optical, three-dimensional analysis of an asymmetric compound parabolic collector (ACPC) with an integrated hybrid photovoltaic/thermal (PV/T) receiver with the aim of establishing a sustainable approach in two ways: firstly, by determining the optimal tilt angle for operations, and secondly, by introducing an innovative simulation method which reduces computational cost while calculating thermal performance. Initially the Incident Angle Modifier (IAM) was calculated for a wide range of incident angles, and the ray-tracing results were verified using three different simulation tools (Tonatiuh, COMSOL, and SolidWorks) with mean deviations being lower than 4%. The optimal tilt angle of the collector was determined for seven months of the year by conducting a detailed ray-tracing analysis for the mean day of each month considering whole day operation. In the thermal analysis part, the authors introduced novel numerical modeling for numerical simulations. This modeling method, designed with sustainability in mind, enables lighter computational domains for the air gap while achieving accurate numerical results. The approach was established using two distinct simulation tools: COMSOL and SolidWorks. From the optical analysis, it was found that in all months examined there is a four-hour time range around solar noon in which the optimum tilt angle remains constant at a value of 30°. The numerical models constructed for the thermal analysis were verified with each other (6.15% mean deviation) and validated through experimental results taken from the literature regarding the examined collector (<6% mean deviation). In addition, the two simulation tools exhibited a deviation of around 6% between each other. Finally, the thermal performance of the collector was investigated for the mean day of September at solar noon by adopting the optimal tilt angle for that month according to the optical analysis, considering inlet temperatures from 20 °C up to 80 °C.

All four serotypes of the dengue virus (DENV1–4) cause a phenotypically similar illness, but serial infections from different serotypes increase the risk of severe disease. Thus, genomic surveillance of circulating viruses is important to detect serotype switches that precede community outbreaks of disproportionate magnitude. A phylogenetic analysis was conducted on near full length DENV genomes sequenced from serum collected from a prospective cohort study from the Colombo district, Sri Lanka during a 28-month period using Oxford nanopore technology, and the consensus sequences were analyzed using maximum likelihood and Bayesian evolutionary analysis. From 523 patients, 328 DENV sequences were successfully generated (DENV1: 43, DENV2: 219, DENV3:66). Most circulating sequences originated from a common ancestor that was estimated to have existed from around 2010 for DENV2 and around 2015/2016 for DENV1 and DENV3. Four distinct outbreaks coinciding with monsoon rain seasons were identified during the observation period mostly driven by DENV2 cosmopolitan genotype, except for a large outbreak in 2019 contributed by DENV3 genotype I. This serotype switch did not result in a more clinically severe illness. Phylogeographic analyses showed that all outbreaks started within Colombo city and then spread to the rest of the district. In 2019, DENV3 genotype I, previously, rarely reported in Sri Lanka, is likely to have contributed to a disease outbreak. However, this did not result in more severe disease in those infected, probably due to pre-existing DENV3 immunity in the community. Targeted vector control within Colombo city before anticipated seasonal outbreaks may help to limit the geographic spread of outbreaks.

Published: June 2023

Retinopathy is a recently recognized complication of dengue, affecting up to 10% of hospitalized patients. Research on the pathogenesis has focused largely on effects of dengue virus (DENV) at the blood–retinal barrier. Involvement of retinal Müller glial cells has received little attention, although this cell population contributes to the pathology of other intraocular infections. The goal of our work was to establish the susceptibility of Müller cells to infection with DENV and to identify characteristics of the cellular antiviral, inflammatory, and immunomodulatory responses to DENV infection in vitro. Primary human Müller cell isolates and the MIO-M1 human Müller cell line were infected with the laboratory-adapted Mon601 strain and DENV serotype 1 and 2 field isolates, and cell–DENV interactions were investigated by immunolabelling and quantitative real-time polymerase chain reaction. Müller cells were susceptible to DENV infection, but experiments involving primary cell isolates indicated inter-individual variation. Viral infection induced an inflammatory response (including tumour necrosis factor-α, interleukin [IL]-1β, and IL-6) and an immunomodulatory response (including programmed death-ligand [PD-L]1 and PD-L2). The type I interferon response was muted in the Müller cell line compared to primary cell isolates. The highest infectivity and cell responses were observed in the laboratory-adapted strain, and overall, infectivity and cell responses were stronger in DENV2 strains. This work demonstrates that Müller cells mount an antiviral and immune response to DENV infection, and that this response varies across cell isolates and DENV strain. The research provides a direction for future efforts to understand the role of human retinal Müller glial cells in dengue retinopathy.

Published: June 2023

The humoral immune response and safety of the fourth dose of the coronavirus disease 2019 (COVID-19) vaccine in solid organ transplant (SOT) recipients need to be fully elucidated. We conducted a systematic review and meta-analysis to assess the efficacy and safety associated with this additional dose of the COVID-19 vaccine in the SOT recipients. A comprehensive search was conducted to identify studies on SOT patients without prior natural SARS-CoV-2 infection who received the fourth dose of the COVID-19 vaccine. Serological antibody responses following vaccination were synthesized by a meta-analysis of proportions. The proportions for each outcome were integrated by using a random-effects model. Approximately 56–92% of the SOT patients developed a humoral immune response, and the pooled seroprevalence rate was 75% (95% confidence interval [CI], 62–82%) after administering the third vaccine dose. Following the fourth dose of vaccination, approximately 76–95% of the patients developed a humoral immune response. The pooled seroprevalence rate after the fourth dose was 85% (95% CI, 79–91%). Of the patients who initially tested seronegative after the second dose, approximately 22–76% of patients subsequently became seropositive after the third dose. The pooled seroconversion rate for the third dose was 47% (95% CI, 31–64%). Among the patients who were seronegative after the third dose, approximately 25–76% turned seropositive after the fourth dose. The pooled seroconversion rate after the fourth dose was 51% (95% CI, 40–63%). Safety data were reported in three studies, demonstrating that adverse effects following the fourth dose were generally mild, and patients with these adverse effects did not require hospitalization. No transplant rejection or serious adverse events were observed. A fourth dose of the COVID-19 vaccine in SOT recipients was associated with an improved humoral immune response, and the vaccine was considered relatively safe.

Published: June 2023

This study explored the application of machine learning, specifically artificial neural network (ANN), to create prediction models for manganese (Mn) concentration in soil and surface water (SW) on the island province with two open mine pits overflowing to two major rivers that experienced mining disasters. The two ANN models were created to predict Mn concentrations in soil and SW from 12 and 14 input parameters for soil and SW, respectively. These input parameters were extracted from extensive field data collected at the site during sampling program in 2019, 2021, 2022, and initially processed with spatial analysis via geographic information system (GIS). All datasets were then divided for model training and validation, using 85% and 15% ratio, respectively. Performance evaluation of each model with mean absolute percentage error (MAPE) and root mean squared error (RMSE) confirmed the accuracy of both models. The soil Mn model achieved MAPE and RMSE values of 2.01% and 23.98, respectively. The SW Mn model was split into two models based on SW Mn values within the 0–1 mg/L range and >1 mg/L range. The SW Mn model for >1 mg/L performed better with MAPE and RMSE of 4.61% and 0.17, respectively. Feature reduction was also conducted to identify how the models will perform if some input parameters were excluded. Result showed sufficient accuracy can still be obtained with the removal of 4–5 input parameters. This study and these models highlight the benefit of ANN to the scientific community and government units, for predicting Mn concentration, of similar environmental conditions.
Comparative Biotic Monitoring of a Modified Denil Fishway and a Pool and Weir Fishway on a Small Tributary in the Upper Trout Region
Authors: Seidl Georg , Schneider Josef
Published: June 2023

Modified Denil fishways have a centred gabion containing gravel and are intended to enable the free passage of riverbed-oriented species and invertebrates. An experimental plant was built at a small hydropower station which provided a newly arranged Denil fishway and a pool and weir fishway parallel to one another. It was possible to alternately operate the systems for monitoring purposes owing to the parallel design, allowing an appropriate comparison and analysis of the results to be carried out. The primary objective of this study is to qualitatively and quantitatively compare the size selectivity and ascent numbers between the new development and the conventional construction type. An important component of this study is the test to prove the passage of bullheads in the modified Denil fishway using an experimental set-up. The results of this study depict a similar size distribution of ascended fish in both construction types and thus provide no evidence of selectivity for small fish sizes. Likewise, no deficit of the modified Denil fishway compared with the pool and weir fishway could be proven within the scope of a monitoring. The successful passage of bullheads could be demonstrated in the experiment as well as during monitoring.
Russian Science in Surmounting Sanctions
Authors: Pashinceva N. I.
Published: June 2023

In this article, building on the data of oﬃcial Russian statistics, the author analyzes the development of the organization of scientiﬁc activity over the last decade, including compared to 2014 – the initial period of anti-Russia sanctions and compared to 2018 – the year before theCOVID-19 pandemic. The paper describes sanctions imposed by a number of unfriendly countries, namely, the refusal to cooperate inmany spheres, including the economy, science, and education. The article considers initial measures to neutralize sanctions. In particular, Russia proposed to create educational «hubs» in the Asia-Paciﬁc region based on the association of the leading universities and scientiﬁc institutions for the training of a skilled workforce to implement priority directions of the development of the economy in Russia and the countries of South-East Asia, taking into account their relevance in the real economy sector. The paper analyses issues of integration of science, higher education, and industry, which contributes to the increase of eﬃciency and eﬀectiveness of research, quality of education, and training of scientiﬁc and technical personnel, as well as the inﬂow of youth in the research and development sphere.

The author outlines the directions for the development of the global information/digital society concerning the demand for new digital technologies, which, year after year, are being revised, updated, and improved. High emphasis is placed on the processes of digital transformation, which have a widespread inﬂuence on scientiﬁc activities, so much so that 2022–2031 were proclaimed as the Decade of Science and Technology. For instance, by 2024, as part of this program, a series of works will be performed covering the transfer of all state information systems to a uniﬁed digital GosTech platform, which in the current complicated conditions will better the quality of public services provided to businesses and citizens.

Published: June 2023

Objetivo. Caracterizar as Infecções Primárias de Corrente Sanguínea (IPCS) em um hospital universitário do interior do Paraná. Método. Trata-se de estudo documental, longitudinal, retrospectivo e quantitativo, realizado através da análise dos registros das notificações das Infecções Primárias de Corrente Sanguínea ocorridas entre janeiro e dezembro de 2020. Resultados. Identificou-se 452 (100%) Infecções Relacionadas à Assistência à Saúde (IRAS), das quais 117 (26%) eram relativas à corrente sanguínea. A ocorrência foi maior em pacientes do sexo masculino (60%), internados na pediatria (23%) e neurologia (21%). A faixa etária com menor frequência de infecção foi de 20 e 40 anos. Detectou-se 20 tipos de microrganismos nas hemoculturas, sendo Staphylococcus spp. (44%) e o Acinetobacter baumannii (15%) os mais frequentes. 43% dos microrganismos apresentaram resistência a algum tipo de antimicrobiano. Conclusão. A identificação do perfil das IPCS possibilita instituir medidas baseadas em evidências, entretanto, no estudo observamos que apesar das medidas estabelecidas pelo SCIH ainda existe uma lacuna entre as recomendações para controle de IRAS e a prática assistencial. Reconhece-se que quando os serviços de saúde e suas equipes estão cientes da magnitude do problema e aderem as medidas preconizadas é possível minimizar consideravelmente o impacto das IRAS. À vista disso, salienta-se a importância de realizar estudos sobre essa problemática. Nessa perspectiva, a educação continuada tem papel relevante na sensibilização dos profissionais para adoção de práticas assistenciais seguras. Como limitação do estudo, apesar de o referido serviço realizar busca ativa rigorosa dos casos de IRAS, reconhecemos a possibilidade de substantificação de casos.

Published: June 2023

The 4-H Health Rocks! curriculum aims to reduce use of tobacco, alcohol, and other drugs and promote healthful lifestyle choices among 8- to 14-year-old youths. A retrospective "post-then-pre" survey of Tennessee participants was aimed at describing the demographic characteristics of participants and investigating respondents' perceptions of program outcomes. Although positive, significant results in youths' perceived knowledge, skills, and assets were found, the majority of youths reported no change from before program participation to after program participation. Recommendations include addressing the need for additional research that aligns respondents' perceptions with program delivery settings and the need to explore different evaluation approaches.

Authors: Voelz Benjamin , Payne Caleigh , Hulbert Lindsey , Stevenson Jeffrey , Brouk Michael , Mendonça Luis
Published: June 2023

A section of the Kansas Dairy Producers' Needs Survey evaluated needs related to education on reproductive management and the most common reproductive management practices used on Kansas dairy farms. Of the 312 surveys mailed to dairy producers, 70 were returned fully completed. Results indicate that producers need education on the topic of reproduction and that reproductive management practices and herd sizes are related to where farms are located in the state. Consequently, future Extension reproductive management programming should reflect the diversity of Kansas's dairy industry. Moreover, the results presented align with earlier data from a nationwide survey and therefore may have applicability on a national scale.

Published: June 2023

This paper makes a critical analysis of the accessibility, especially for people with reduced mobility, of the most relevant tourist resources in the town of Vieira do Minho, a municipality belonging to the district of Braga, located in the Northwest of the Iberian Peninsula. The research presented here aims to increase the quality of local tourist attractions, presenting strategies aimed at improving the accessibility of these attractions by people with reduced mobility. It is also intended to answer the following research questions: (1) how accessible are the tourist resources in Vieira do Minho? (2) What are the conditions offered by the various points of tourist interest in the village of Vieira do Minho? (3) What are the barriers that prevent people with reduced mobility from enjoying tourism in this destination? (4) What strategies can be implemented in the various points of tourist interest to enhance accessibility for all people? The methodology used was the structured observation of accessibility conditions in the main cultural spaces, green spaces, gardens, accommodation and restaurants in Vieira do Minho. It is therefore a matter of systematically observing and recording a set of previously established categories. The results of the investigation make it clear that the municipality of Vieira do Minho is on the right path to become, in the near future, a fully accessible destination for people with reduced mobility. Nevertheless, the present investigation detected some gaps, namely in leisure parks, accommodation units, municipal swimming pools, exhibition houses, among others. In order to become a destination of excellence, in terms of accessible tourism, Vieira do Minho will still have to make some improvements to the tourist offer it has, such as installing ramps and elevators, but also improving the quality of the floors in the tourist resources mentioned in this project.

Service quality refers to the level of accuracy in meeting the needs and expectations of customers. Meanwhile, facilities are the physical amenities provided by service providers to enhance consumer comfort. Price perception also influences purchasing decisions, while company image is the result of customers comparing the attributes of a company. SPSS Version 25 is used to analyze data related to purchasing decisions. The results of the t-test hypothesis testing show that service quality, facilities, price perception, and company image have a positive and significant partial influence on purchasing decisions. Based on this research, it was found that the multiple linear regression model produces the following equation: Y = 1.821 + 0.271X_1 + 0.193X_2 + 0.197X_3 + 0.186X_4 + µ. The equation results show that the service quality variable (X1) has a t-value of 2.756 > t-table 1.985, the facilities variable (X2) has a t-value of 2.156 > t-table 1.985, the price perception variable (X3) has a t-value of 2.052 > t-table 1.985, and the company image variable (X4) has a t-value of 2.115 > t-table 1.985. Furthermore, the Adjusted R2 value of 0.529 indicates that the independent variables, namely service quality, facilities, price perception, and company image, explain 52.9% of the variation in purchasing decisions, while the remaining 47.1% is influenced by other variables not included in this study, such as product promotions, timeliness, and ship schedules.
Field Burials, Memorial Graves, and the Postwar Search for Tarawa’s Fallen
Authors: Roecker Geoffrey W.
Published: June 2023

The battle for the Tarawa atoll—and, specifically, the V Amphibious Corps assault on the island of Betio during World War II—resulted in an enormous and highly publicized loss of American lives. Grieving families were assured that every possible care was given to their fallen Marines and sailors, and photographs of beautiful cemeteries appeared in magazines and print. This belied the reality of the situation: most of the “graves” were only memorials, and a postwar effort to recover the dead was markedly unsuccessful. Representatives from the U.S. Army, Navy, and Marine Corps pointed fingers until Navy inspector general Charles A. Lockwood issued a report blaming “a series of errors . . . and a series of unavoidable circumstances” for the fiasco. This article examines the factors contributing to the nonrecoverability of hundreds of the fallen and describes the challenges facing researchers and archaeologists who continue the search for the lost graves of Betio.
Marine Hawk Missiles in Guantanamo Bay during the Cuban Missile Crisis
Authors: Romanych Marc
Published: June 2023

During the Cuban missile crisis, the U.S. Marine Corps deployed a Hawk air defense missile battery from the 3d Light Antiaircraft Missile (LAAM) Battalion to Guantánamo Bay, Cuba, to protect the U.S. naval base from a surprise low-level air attack by Soviet and Cuban aircraft. The battalion was alerted and airlifted from Twentynine Palms, California, to Cherry Point, North Carolina, with its Battery C deployed forward into Cuba. The deployment validated the readiness of the Corps’ LAAM battalions to employ the Hawk system in support of expeditionary forces. However, the story of the LAAM battalions and deployment of 3d LAAM to Guantánamo Bay is not well known or documented because few official records of the LAAM battalions from the early 1960s exist. This article uses Marine Corps Base Twentynine Palms’s newspaper to provide context along with veterans’ first-hand experiences to fill in the details of the LAAM battalions before and during the Cuban missile crisis.

Kejadian stunting merupakan masalah gizi yang dialami tidak

hanya di Indonesia akan tetapi dialami oleh dunia saat ini.

Stunting merupakan kondisi dimana anak memiliki tinggi badan

yang kurang jika dibandingkan dengan anak seusianya. Hal ini

terjadi karena kurangnya asupan gizi pada anak pada 1000 hari

pertama kehidupan yaitu pada anak usia semenjak dalam rahim

sampai dengan anak usia 2 tahun. Pemenuhan asupan gizi sangat

penting dilakukan sejak hamil. Faktor - faktor yang berpengaruh

terhadap pemenuhan tersebut salah satunya adalah pengetahuan.

Pengetahuan merupakan hasil ”tahu” dan ini terjadi setelah orang

melaksanakan pengideraan terhadap suatu obyek tertentu. Faktor

pengetahuan mendukung terciptanya suatu tindakan yang nyata

dan diharapkan setelah orang memperoleh pengetahuan

kemudian timbul suatu sikap sehingga akan dapat terjadi tindakan

nyata dari orang tersebut. Tujuan dalam penelitian ini

Published: June 2023

Algoritme Huffman dan Algoritme Huffman Weaven-Hankamer adalah dua algoritme pengodean sumber yang diterapkan secara umum untuk pengodean teks. Kedua algoritme ini membutuhkan lebih banyak waktu untuk menyelesaikan prosesnya karena memiliki banyak tahapan. Oleh karena itu, penelitian ini bertujuan untuk membuat user interface menggunakan MATLAB yang dapat menyimulasikan proses kedua algoritme dan mampu memberikan hasil yang sangat akurat dengan lebih cepat. Ada dua skenario pada penelitian ini. Terdapat delapan kali percobaan pada masing-masing skenario dengan menggunakan jumlah karakter yang sama yaitu 15 sampai 22 ribu. Karakter ELSE juga terdapat dalam sumber informasi yang digunakan, namun jumlahnya berbeda dibandingkan dengan karakter biasa. Skenario pertama menggunakan lebih banyak karakter ELSE, sedangkan skenario kedua menggunakan karakter ELSE yang lebih sedikit dibandingkan dengan eksperimen biasa. Hasil penelitian menunjukkan bahwa algoritme Huffman lebih efisien pada skenario pertama dibandingkan dengan Huffman Weaven-Hankamer, dimana selisih rata-ratanya 2,24 persen. Meskipun algoritme Huffman masih tampil lebih baik pada percobaan kedua, perbedaan efisiensi rata-rata nya lebih kecil, 1,48 persen, jika dibandingkan dengan pendekatan pertama. Selain itu, hasil juga menunjukkan bahwa pohon algoritme Huffman Weaven Hankamer lebih sederhana dibandingkan dengan pohon algoritme Huffman.

Published: June 2023

Independent Power Plant (IPP) Pembangkit Listrik Tenaga Surya (PLTS) Oelpuah di Kabupaten Kupang telah dioperasikan sejak November 2015 dengan kapasitas 5 MWp. Namun daya maksimum yang dihasilkan belum mencapai produksi daya yang optimal, yakni hanya pada kisaran 3.000 - 4.000 kW. Oleh karena itu diperlukan suatu kajian untuk mengidentifikasi dan menganalisis penurunan daya keluaran yang terjadi. Hasil pengukuran bulan Desember menunjukkan radiasi matahari, temperatur dan kerusakan peralatan berpengaruh cukup signifikan terhadap penurunan daya keluaran sebesar 35,7%. Kemudian, berdasarkan hasil simulasi menunjukkan produksi daya keluaran yang dihasilkan oleh array ketika tilt 15° dan azimuth 0° adalah 4.000 kW dengan E grid 9.111 MWh/tahun. Daya ini akan meningkat menjadi 4.100 kW dengan E grid 9.113 MWh/tahun ketika posisi tilt 14° dan azimuth -5°. Sebaliknya, penurunan daya keluaran dapat terjadi  akibat pengaruh perubahan  posisi tilt dan azimuth sebesar 0,10%. Faktor lain yang berpengaruh adalah faktor internal  seperti rugi-rugi inverter 1,68%  dan  rugi-rugi kualitas panel surya 3%.  Sementara dari sisi faktor eksternal seperti rugi-rugi panel surya karena tingkat radiasi (0,16%), temperatur (13,5%), GHI (2,40%), dan peralatan yang rusak (25%).

Patrimonio cultural y efectivización de derechos

Published: June 2023

El objetivo de esta investigación es analizar las formas en que las “artesanías en barro”, el “rap originario” y los tejidos en telar que realizan referentes de las comunidades qom Dalaxaic´ Na´ac, Nam Qom y Nqayañec´pi Naqota´at, de la periferia de la ciudad de La Plata, son seleccionadas, jerarquizadas y valoradas por la propia gente por sobre otros saberes, bienes y prácticas. Ello se realiza a los fines de observar cómo se ponen en juego en la construcción identitaria, en las acciones por su reconocimiento y revalorización étnica, en situaciones históricas concretas y en el marco de relaciones interétnicas asimétricas y desiguales. Estas prácticas son comprendidas en términos de patrimonio cultural, entendido como una construcción social, histórica y culturalmente situada. Sin disociar sus dimensiones material e inmaterial, es decir en términos integrales, y como campo en disputa -en tanto quienes participan del mismo luchan por su apropiación y sus formas de significación-. Las nociones de patrimonio cultural de referencia, de herencia cultural y de patrimonio vivo así como las conceptualizaciones sobre la identidad, la etnicidad y la memoria, habilitan la comprensión de los procesos de patrimonialización que encarna la gente qom con quien trabajamos. Teniendo en cuenta el momento organizativo en que las familias qom se encuentran, así como su situación socio económica y las características del barrio donde desarrollan sus vidas, señalamos que las artesanías, el rap y los tejidos forman parte del patrimonio cultural de referencia del pueblo qom, en tanto expresiones artísticas que contribuyen a que el colectivo se reconozca como tal. Se relacionan por tanto íntimamente con la construcción y reproducción de su identidad. Son bienes heredados de generaciones precedentes que las comunidades viven a diario y ocupan un lugar importante en su memoria, la del pueblo a las que éstas pertenecen y dan lugar a su continuidad en el presente. Son una herencia cultural, material y simbólica que se traduce en una dimensión espacial, vinculando a dicho colectivo con un territorio puntual. Son una reserva de significados, ideas y sentimientos que los ligan al monte del cual provienen y al pueblo al que pertenecen. Los resultados que aquí se presentan son producto de una “producción conjunta de conocimiento” a través de la cual esperamos contribuir al reconocimiento del patrimonio cultural de las familias qom que habitan en La Plata y a su valoración en un contexto de inequidad socioeconómica y racismo.
Tailored Timing Approaches for Enhancing Learning in Robot-Child Tutoring

Published: June 2023

In the realm of education, it is common practice to incorporate non-task breaks to cater to children's limited attention spans and provide cognitive rest. With the potential to support learning, robots can play a crucial role in offering personalized breaks tailored to individual children. This research focuses on investigating personalized timing strategies for delivering breaks to young learners during robot tutoring interactions. We develop an independent robot tutoring system that monitors students' performance and administers break activities based on personalized schedules aligned with their performance levels. To explore the effects of various break strategies during tutoring, we conduct a field study. By comparing a fixed timing strategy with two personalized approaches - a reward strategy (break timing personalized to performance improvements) and a refocus strategy (break timing personalized to performance declines) - we demonstrate that the personalized strategies effectively enhance learning outcomes for children compared to the fixed strategy. Our findings also reveal immediate advantages in terms of increased efficiency and accuracy in completing educational tasks following personalized breaks, highlighting the restorative effects of breaks when provided at the appropriate moments.

Published: June 2023

Covid-19 is an infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The spread of Covid-19 in Indonesia has grown rapidly that the World Health Organization (WHO) has declared Covid-19 a pandemic. Covid-19 cases have spread to 34 provinces in Indonesia. Covid-19 data in Indonesia involves space and time so the appropriate modeling is the space-time model. Space-time modeling of the Covid-19 case in 34 provinces in Indonesia using the Generalized Space-Time Autoregressive Integrated Moving Average (GSTARIMA) model has not been carried out. The purpose of this research is to get the best GSTARIMA model and forecat the Covid-19 case for the next several times. This model incorporates time and location interdependence with different parameters for each location. Identification of the order of the AR and MA was carried out through the STACF and STPACF plots. For simplicity of interpretation, the spatial order is chosen first order. In this study, the queen contiguity and the inverse distance location weighting matrix were used. The parameter estimation used is Ordinary Least Square (OLS). The results show that the best model for predicting Covid-19 cases in 34 provinces in Indonesia is the GSTARIMA model (1,1,0)1 using an inverse distance weighting matrix with the smallest RMSE value of 1.22.Keywords: Covid-19, GSTARIMA, Queen Contiguity, Inverse Distance, OLS.
Escritura y praxis jesuítica. Apuntes desde una lectura distante de las cartas anuas de la provincia del Paraguay (1632-1762)
Authors: Vega Fabián R.
Published: June 2023

Inspirado en las humanidades digitales, este artículo lleva adelante una lec- tura distante de las cartas anuas del Paraguay jesuítico (1632-1762), documentos que con- tienen relatos edificantes de las actividades apostólicas de los jesuitas en esta región. El análisis textual muestra que las cartas anuas estuvieron asociadas a una praxis peculiar, porque privilegiaron las referencias al objetivo salvífico de la Compañía de Jesús y la ad- ministración de ciertos sacramentos, en particular el de la confesión. Asimismo, exhibe que estos documentos evolucionaron a lo largo del tiempo: inicialmente centrados en las misiones de guaraníes, se enfocaron cada vez más en las ciudades y colegios y en ciertas prácticas devocionales, como los ejercicios espirituales.
Los perpetradores chilenos en Chili-impressions: la represión desde una perspectiva transnacional
Authors: Amaral de Aguiar Carolina
Published: June 2023

Esta investigación dialoga con estudios recientes sobre la figura del perpetrador con el objetivo de analizar cómo se representa a los agentes de la represión chilena en el audiovisual. Por medio de metodologías procedentes de los estudios sobre las relaciones entre audiovisual e historia, este artículo analiza los mecanismos narrativos que utiliza la serie documental de la televisión pública francesa Chili-impressions (1978), dirigida por el exiliado español José María Berzosa, para construir una oposición a la Junta Militar chilena en los años setenta. El producto audiovisual estudiado es emblemático, pues alcanzó una gran visibilidad en su época, tras haber sido inicialmente suspendida su exhibición por la justicia francesa. Además, contribuyó con la difusión de una memoria negativa de la dictadura en el extranjero
