Compreensão de docentes do ensino fundamental sobre sustentabilidade socioecológica rumo à aprendizagem baseada em problemas
Authors: Silva do Vale Guedes Alline , Pedro da Silva Valdenildo 
Published: December 2024

Devido a atual situação de emergência planetária, a educação para a sustentabilidade socioecológica necessita estar presente nos currículos e práticas docentes do ensino fundamental. A utilização de metodologias ativas como a aprendizagem baseada em problemas pode se mostrar como uma alternativa na construção do pensamento crítico dos indivíduos rumo a uma sociedade mais sustentável. Objetiva-se investigar neste estudo a percepção de docentes do ensino fundamental da Escola Estadual Clara Camarão sobre domínio e abordagem da sustentabilidade socioecológica rumo a uma aprendizagem baseada em problemas. Trata-se de uma pesquisa qualitativa, em que foi usada a coleta de dados com 16 docentes por meio de um questionário on-line via Google Forms, focando-se na compreensão mais abrangente de seus pensamentos sobre sustentabilidade na prática educativa. A análise de dados, embasada no suporte teórico, foi realizada por meio da técnica de análise de conteúdo de Bardin. Os resultados mostraram que os docentes têm contemplado muito pouco a discussão da sustentabilidade socioecológica a partir da aprendizagem baseada em problemas, demonstrando certa fragilidade da formação inicial e/ou continuada dos docentes sobre a abordagem da sustentabilidade socioecológica. Conclui-se que embora as formações dos docentes sobre a temática tenham se mostrado insuficientes, constatou-se que os docentes estão dispostos a dinamizar a aprendizagem sobre sustentabilidade socioecológica na escola por meio da aprendizagem baseada em problemas.

Com o aumento da oferta dos chamados cursos online abertos e massivos, conhecidos por seu acrônimo MOOC (Massive Open Online Couses), na qual permitem que as pessoas aprendam conteúdos de maneira mais acessível e livre, esse trabalho tem por objetivo analisar de que forma esses cursos MOOCs estão sendo utilizados no Ensino Superior, direcionando um olhar às possibilidades metodológicas de Ensino, a partir da inserção no ambiente escolar. Trata-se de uma pesquisa qualitativa de caráter exploratório por meio do método de mapeamento sistemática. A análise de dados foi realizada com o apoio do minerador de texto SOBEK. O recorte temporal utilizado nessa pesquisa delimitou-se em 2018 a 2020, tendo como resultado a acentuação sobre a produção científica dos MOOCs, e como principal enfoque o ensino superior. Ainda vale destacar que, apesar da forte tendência ao crescimento de cursos inseridos na modalidade MOOCs, as implementações deles demandam de conhecimentos referentes a princípios, processos e práticas pedagógicas em relação ao ensino e aprendizagem mediado por computador. Assim espera-se que esse estudo auxilie nas discussões da temática e como sugestões para trabalhos futuros, propõe-se o desenvolvimento de uma pesquisa utilizando protótipo MOOC, atrelando teoria e prática em uma área específica utilizando como um recurso tecnológico em sala de aula, sendo ela remota ou presencial.
La complejidad del primer año de vida universitaria.
Authors: Abi Saad Vanina , Boggio Carla , Poletti Lucía María 
Published: December 2024

El primer año de vida universitaria configura un desafío adaptativo y ocupacional complejo para los estudiantes, siendo el año donde se reportan mayores niveles de deserción dentro del sistema a pesar de los esfuerzos que la universidad realiza para aumentar las tasas de retención y permanencia.
Si bien múltiples estudios permiten comprender algunas de las diversas variables que aportan a esta complejidad, este trabajo busca realizar un aporte a la comprensión de la temática desde una perspectiva poco explorada: la dimensión ocupacional. Con apoyo en los postulados del Modelo de la Ocupación Humana y la Ciencia de la Ocupación buscará avanzar en una explicación de los cambios que transitan los estudiantes en perspectiva ocupacional, partiendo del análisis de la persona como sistema dinámico complejo, en permanente relación dialéctica con su ambiente, compuesta de tres elementos estructurales: volición, habituación y capacidad de desempeño, los que se transforman durante el proceso dando lugar al desarrollo de diferentes maneras de participar ocupacionalmente, de vivir las demandas del ambiente, de dar respuesta a ellas y de alcanzar las metas académicas.
Development of Interactive Multimedia "ABBD: Aku Bisa Belajar Disiplin" to Improve Student Discipline in Early Childhood Education
Authors: Aisyah Ratu Nur 
Published: December 2024

This study aimed to address low technology utilization and poor student discipline in schools by developing interactive multimedia titled ABBD: Aku Bisa Belajar Disiplin. Using the ADDIE model (Analyze, Design, Development, Implementation, Evaluation), this Research and Development (RnD) study was conducted over six months (March-August 2023) at RA Mutiara Iman. Participants included ten students aged 5–6 years, selected randomly, while media and material experts and field practitioners were purposively chosen for feasibility evaluations. Data were collected through observations, interviews, questionnaires, and documentation. Qualitative data were analyzed using the Miles and Huberman model, while quantitative data were assessed using Likert and Guttman scales. The results showed significant improvement in student discipline, with scores increasing from 66% pre-intervention to 85% post-intervention. Feasibility evaluations by media experts scored 88.9% (very good), while material experts scored 97.7% (very good). Field practitioners, including principals and teachers, rated the multimedia between 95.3%–100% (very good). Trials with students revealed high acceptance, with one-to-one trials scoring 90% and small-group trials scoring 92.5%. The multimedia incorporated audio, video, animations, and interactive buttons, ensuring user-friendly and age-appropriate content. These findings underscore the effectiveness of "ABBD" in improving discipline among early childhood students and highlight the potential for integrating technology into educational practices. The study's limitations include its focus on a small sample size and short-term evaluation, which may restrict the generalizability and understanding of long-term impacts. Future research should explore its long-term impacts and scalability in diverse educational settings to maximize its broader application.
Генеративный искусственный интеллект в российских православных сообществах: восприятие и практики использования
Authors: Душакова Ирина Сергеевна , Душакова Наталья Сергеевна 
Published: December 2024

В статье через призму социального конструирования технологий (SCOT) рассматриваются восприятие и практики использования генеративного искусственного интеллекта в религиозных сообществах России. Цель исследования — выявление интерпретативной гибкости генеративного ИИ как технологического артефакта в православных сообществах России (последователей Русской православной церкви, старообрядцев разных согласий). Авторы исходят из гипотезы о том, что первое время после массового релиза генеративного ИИ (ChatGPT, Midjourney и др. инструментов) набор контекстов и областей применения, в которых генеративный ИИ видим и понятен, довольно узок. Кроме того, учитывая новизну технологий и низкую вероятность наличия предыдущего опыта в обращении с ними, начало взаимодействия характеризуется высокой гибкостью интерпретаций генеративного ИИ. Для выявления набора практик и контекстов использования генеративного ИИ в православных сообществах проводится анализ их каналов и площадок в социальных медиа и СМИ, что позволяет говорить о конструировании технологии самими сообществами в связке с общим информационным полем. Хронологические рамки исследования охватывают период с 1 января по 31 декабря 2023 г. Во избежание смещения выборки при ручном отборе материала для работы привлекается база данных «Медиалогия» (мониторинг соцсетей).
Как показывает анализ данных, большая часть дискуссий выстраивается вокруг попыток установить границы применения новой технологии и выявить связанные с ней опасности. Сомнения в целесообразности применения искусственного интеллекта не затрагивают его утилитарное использование: граница допустимого очерчивается в сфере религиозных смыслов. Набор практик использования генеративного искусственного интеллекта на текущий момент достаточно узок, при этом самая распространеная практика — генерация или обработка изображений.

Abstract

Objectives
Automated immunoassays for 1,25-dihydroxyvitamin D (1,25(OH)2D) have increased the use of serum measurements in clinical and research settings, but disagreement with LC-MS/MS methods remains an issue.

Methods
In this study, we examined this problem using samples obtained from healthy young adults, n=80, mean age 21.7 (18–32) years, and a large cohort of paediatric samples, n=422, mean age 7.3 (0–17) years. We compared serum concentrations of 1,25(OH)2D3/D2 produced by the DiaSorin LIAISON® XL immunoassay against an LC-MS/MS method with immunoaffinity enrichment and DAPTAD derivation.

Results
Both assays showed intra/inter-assay imprecision of ≤9.4 % across their respective assay range. DEQAS between April 2020 to Jan 2024 (n=80) showed mean bias (SD, 95 %CI) for DiaSorin −0.6 % (6.2, −12.8 to 11.6) and LC-MS/MS of +1.3 % (7.4, −13.3 to 15.8) against their respective method group means. Comparison of measurements in the adult samples showed a strong correlation (r2=0.9331) and concordance (CCC=0.959) between the two methods. LC-MS/MS values were lower than DiaSorin by an overall mean (±SD, 95 %CI) of −1.6 (±14.3, −29.6 to 26.5) pmol/L with an increased negative bias at higher concentrations. In the paediatric samples, weaker correlation (r2=0.6536) and concordance (CCC=0.782) were observed, with greater bias mean (±SD, 95 %CI) of −9.8 (±23.4, −55.7 to 35.9) pmol/L. The variability in the paediatric samples was not associated with concentration or participant age. There was an increase in the correlation and concordance when 1,25(OH)2D2 was included in the analysis.

Conclusions
It is likely that the metabolites of vitamin D present in the paediatric population contributed to the measurement of 1,25(OH)2D. The inconsistent agreement highlights the need for better assay harmonisation and paediatric reference intervals using LC-MS/MS method.
High tribo-corrosion resistance of Ni-Cr-5Al2O3 thermal spray coating: a comparison of post processing techniques
Authors: Garg Mayank , Grewal Harpreet Singh , Arora Harpreet Singh 
Published: December 2024

Abstract
Engineering materials are known to show degradation in terms of tribo-corrosion characteristics in marine environment. The concurrent increase in erosion and corrosion resistance can make them more appealing for structural applications. The thermal spray coatings are typically used to mitigate the degradation of structural components. Although, the microstructure of as-sprayed coating indicates inconsistency in the form of distinct splats and elemental segregation. Furnace annealing, microwave processing and stationary friction processing (SFP) are performed to improve the non-homogeneous microstructure of the thermal spray coating. SFP has several attractive properties to refine the grain structure and reducing the defects density on the surface. Therefore, SFP has been explored as a surface modification technique for thermal spray coating with an aim to enhance the performance of the processed coating. Slurry erosion and erosion corrosion tests are conducted on as-sprayed and processed coatings at normal and oblique impingement angle. Erosion rate of SFPed specimen is comparatively lower than that of the as-sprayed, furnace annealed and microwave processed specimens in both slurry erosion and erosion corrosion. Furthermore, the SFPed coating indicated least corrosion rate as compare to furnace annealed, microwave coating and as-sprayed coating.
Augmented reality in developing students’ understanding of chemistry triplet: a systematic literature review
Authors: Ribič Luka , Devetak Iztok 
Published: December 2024

Abstract
Augmented Reality (AR) is increasingly finding its way in chemistry education, and it is becoming an important teaching tool to help students understand complex chemical phenomena. Forty-six papers from two databases published between 2018 and 2023 on the implementation of AR in chemistry education with empirical quantitative research design, were analysed. The results show that learning effectiveness is the main objective of AR studies. Technology acceptance questionnaires and achievement tests were the most popular data collection instruments. AR was recognised as a useful and easy to use tool that helps students to improve their learning. However, no study has yet been conducted on effectiveness of AR on students’ understanding of the chemical triplet. Also, some challenges were identified related to technical issues with the AR app and teachers’ resistance to using this technology. Further research is needed to test this technology in different learning settings and with different types of learners.

Authors: Lippi Giuseppe , Ferrari Anna , Visconti Sara , Martini Loredana , Demonte Davide , Lo Cascio Claudia , Capizzi Barbara 
Published: December 2024

Abstract

Objectives
The measurement of fasting glucose is a common practice for lowering the risk of hyperglycemia before an oral glucose tolerance test (OGTT). In this study we analyze advantages and limitations of near-patient measurement of capillary fasting glucose with a portable glucometer or blood sampling and measurement of plasma glucose with laboratory instrumentation.

Methods
The final study population consisted of 241 subjects (mean age: 36 ± 8 years; 97.9 % pregnant women) referred to our local phlebotomy center for an OGTT. Fasting glucose was measured in capillary blood using a near-patient glucometer (glucometer-based strategy) and in plasma with laboratory instrumentation using the hexokinase reference assay (laboratory-based strategy).

Results
The mean turnaround time from sample collection to obtaining the glucose value was longer with the laboratory-based strategy (32 min 8 vs. 8 s). The imprecision of the glucometer was higher than that of the laboratory assay (3.4 vs. 0.8 %). A negative bias of −3.3 % in fasting glucose was found with the glucometer compared to the laboratory measurement. The diagnostic accuracy, sensitivity and specificity of the glucometer for detecting fasting glucose values ≥7.0 mmol/L were 99.2 , 50.0 and 100.0 % compared to the laboratory assay. The glucometer-based strategy had an incremental cost of 0.17€ per patient compared to the laboratory-based strategy.

Conclusions
Screening fasting glucose in capillary blood with a near-patient glucometer instead of measuring fasting plasma glucose with laboratory instrumentation allows faster patient management in the phlebotomy center but is associated with higher imprecision, inaccuracy, costs and avoidable finger pricks.
Maximum sensitivity constrained modified Smith predictor for delayed integrating type stirred tank reactors model
Authors: Gupta Maneesh Kumar , Ajmeri Moina 
Published: December 2024

Abstract
A maximum sensitivity constrained modified Smith predictor consisting of two PD controllers is developed for integrating type continuously stirred tank reactors (CSTRs) model. This CSTR type model approximated as integrating first order plus time delay with and without inverse response processes is challenging to control as it contains integrating term, process time delay and a zero lying in the right half of s-plane. The inner and outer loop PD blocks are tuned to achieve the desired set-point tracking and load disturbance rejection responses using direct synthesis approach. The proposed control is free from integrating action and therefore, smooth setpoint tracking response with no overshoot is obtained which is highly desirable in the process industries. Two design parameters λ and τ are involved in the suggested control whose suitable values are recommended to achieve the desired robustness level by specifying the maximum sensitivities of the inner and outer loop transfer functions. Various illustrative models are considered to show the effectiveness and superiority of the proposed control structure. The system robustness towards process parameter perturbations and load disturbances are investigated in all the examples. Performance of the suggested modified Smith predictor is found superior as compared to the other recently published works.

Published: December 2024

Abstract
The ionosphere plays a critical role in radio wave propagation, impacting satellite-based communication and navigation systems. This study evaluates near-real-time ionosphere maps (NRTIMs) derived from dual-frequency Global Positioning System (GPS) observations and validates them against established ionosphere models. Using dual-frequency Global Navigation Satellite System (GNSS) technology, the research mitigates ionospheric errors by measuring phase delays at L1 and L2 frequencies. Global ionosphere maps (GIMs) generated by the International GNSS Service (IGS) provide essential ionospheric corrections. Our approach combines accurate GPS observations with regional modeling to enhance GNSS positioning accuracy. The results demonstrate the effectiveness of the developed MATLAB algorithm in estimating ionospheric delays, showing strong convergence with GIMs. The results show a significant convergence between the Regional Ionosphere Modeling of RIM, IGS (Final Ionosphere Product), IGU (Ultra Rapid Ionosphere Product), and IGR (Rapid Ionosphere Product), as the highest average values during the 77th DOY of winter 2020 at the CPVG station were 14.753 TECU for RIM and 14.736, 14.7373 and 14.731 TECU at the CPVG station for IGS, IGU, and IGR while the average was for RIM, IGS, IGU, and IGR are respectively lower, with the lowest average values during the 190th DOY of autumn 2020 at station IZMI with a value of 3.5472 TECU for RIM, 3.5541, 3.5421 and 3.5624 TECU at IZMI station for IGS, IGU, and IGR respectively. By achieving strong agreement with existing GIMs and providing high-frequency results, the algorithm improves the reliability of GPS systems by effectively monitoring envelope disturbances.

Diversification in Business Valuation
Authors: Blatter Anja Bettina , Ernst Dietmar , Lang Sarah Maria 
Published: December 2024

Abstract
The importance of the diversification and the related diversification factor in business valuation has not been studied in depth. In CAPM, due to the model assumptions, it is implied that an investor holds a perfectly diversified portfolio, which answers the question of diversification. The objective of this paper is to clarify the definition of diversification and to show how diversification effects can be incorporated into business valuation. Our research contribution entails demonstrating methods to capture the risk situation of an investor based on its asset allocation and then deriving the diversification effect from this assessment. As a methodological approach, we have opted for one that encompasses the most diverse degrees of diversification. Our analysis shows that this approach captures all non-hedged risks and thus performs a stand-alone valuation without diversification effects. If the diversification effect of a specific portfolio is to be included in the valuation, the analyst must shift from a stand-alone approach to a portfolio based approach, where the diversification factor cannot simply be equated with the correlation coefficient but must be calculated using various aggregation methods. Given that the conventional variance-covariance method excludes extreme risks, we propose the use of the copula approach. This approach can enhance risk modeling and yield more accurate results in diversification effect calculations. Our analysis demonstrates that it is possible to effectively model different diversification effects in business valuation. However, this entails substantial data expenses and demands a high degree of methodological expertise from the analyst.
Ethical challenges in collecting pre-existing digital data for linguistic research
Authors: Dalmaijer Evi , Stommel Wyke , Pas Berber , Spooren Wilbert 
Published: December 2024

Abstract
Pre-existing digital data are a valuable resource for linguistic research. Collecting these materials is often thought of as straightforward (“the data exist anyway”) and ethical dilemmas are given little consideration. In this article, we discuss microethical issues we encountered while collecting electronic text messages, photos, and videos posted on a digital platform and app during paramedical treatment. Since ethics and methods are intertwined, we discuss the various ethical and methodological aspects of collecting these sensitive digital data for our linguistic research project and reflect on the benefits and limitations of the choices we made during this process. We specifically highlight the interdependence of ethics with technology and discuss how this can be even more challenging when working in a specific institutional context characterized by different conceptions of ethics and technology. Our article highlights the importance of microethics complementing prevalent ethical guidelines. We show that when pre-existing digital data are available in non-public digital spheres, it is difficult for researchers to define in advance in ethical protocols or guidelines how the data can be collected and what ethical measures should be taken. We argue that ethical reflections should be at the center of research, including research on pre-existing digital data, guiding the decisions to be made at all stages.
Ethical concerns for theoretical research in linguistics: issues and best practices
Authors: Chandra Pritha , D’Alessandro Roberta , Putnam Michael T. 
Published: December 2024

Abstract
Although formal, e.g., generative, approaches to linguistic inquiry are primarily concerned with the analysis of structural patterns, ethical concerns for the elicitation and documentation of empirical data that motivate these analyses persist. In this article, we explicate the challenges to be met and responsibilities that formal linguists must take in data collection, documentation, and analysis to ensure high ethical standards. We direct our attention especially toward research on heritage, minoritized and endangered languages, which have enriched the theoretical landscape in recent decades. Finally, we show that, when proper ethical concerns are recognized and accounted for in formal research, this collective body of research in its current form is also fully capable of respecting the integrity of individual speakers and their communities.
