Authors: Johnson Kathrine , Jung Eulho , Snow Greg , Murray Shannon , Bonk Curtis 
Published: May 2024

In a fully online college introductory statistics class, we incorporated a flexible synchronous course component to provide instructor immediacy and support students who are lacking sufficient prior knowledge when a new topic is introduced. We describe a learning cycle with weekly team quizzes inspired by the readiness assurance process of team-based learning; we interviewed eight students for their perceptions of the course structure. Team quizzes are designed to provide regular formative assessment and feedback in real-time with the goal of improving student satisfaction and success in the course. Overall, students reported that the weekly synchronous sessions contributed to a strong sense of belonging to peers and the instructor, were helpful for their learning and helped them successfully complete the course.

Implications for practice or policy:

Instructors can use regular synchronous team quizzes in a fully online course to improve student engagement, connectedness, persistence and learning.
Instructors can use team quizzes for regular formative assessment and feedback and to facilitate just-in-time intervention.
Plausible role of INPP4A dysregulation in idiopathic pulmonary fibrosis

Published: May 2024

AbstractINPP4A has been shown to be involved in the regulation of cell proliferation and apoptosis of multiple cell types including fibroblasts. Previous reports from our group have demonstrated the role of inositol polyphosphate 4‐phosphatase Type I A (INPP4A) in these functions. Though existing evidences suggest a critical role for INPP4A in the maintenance of lung homeostasis, its role in chronic lung diseases is relatively under explored. In the current study, we made an attempt to understand the regulation of INPP4A in idiopathic pulmonary fibrosis (IPF). Through integration of relevant INPP4A gene expression data from public repositories with our results from in vitro experiments and mouse models, we show that INPP4A is altered in IPF. Interestingly, the direction of the change is dependent both on the disease stage and the region of the lung used. INPP4A was found to be upregulated when analyzed in lung sample representative of the whole lung, but was downregulated in the fibrotic regions of the lung. Similarly, INPP4A was found to be high, compared to controls, only in the early stage of the disease. Though the observed increase in INPP4A was found to be negatively correlated to physiological indices, FVC, and DLCO, of lung function, treatment with anti‐INPP4A antibody worsened the condition in bleomycin treated mice. These contrasting results taken together are suggestive of a nuanced regulation of INPP4A in IPF which is dependent on the disease stage, cellular state and extent of fibrosis in the lung region being analyzed.

Recycling harmful plastic waste to produce a fiber equivalent to carbon fiber reinforced polymer for reinforcement and rehabilitation of structural members
Authors: Nhabih Hussein Talab , Al-Badkubi Mohammad R. K. M. , El-barbary A. A. , Salman Marwa Marza 
Published: May 2024

Abstract
The main idea of this research is to manufacture plastic fibers (PFs) by recycling harmful plastic waste after washing it with water and drying it, then cutting it into strips and immersing them in liquid nitrogen, using a rotating iron basin mixer containing iron balls that touch these strips, producing fibers that are woven later to be similar to carbon-fiber-reinforced polymer (CFRP). This process is the first in the world, and the cost of manufacturing these fibers is very low compared to the cost of producing CFRP, as the cost of producing these fibers is 25 times less than the cost of producing CFRP. All the physical, chemical, and mechanical properties of the manufactured PFs were investigated and compared with the properties of CFRP. In this research, it was found that the manufactured PFs have properties similar to the properties of CFRP. The experimental work consists of casting five reinforced concrete beams with a cross-section of 125 mm × 200 mm and a length of 1,200 mm. They were divided into two groups, each group containing two beams, one of which was reinforced by CFRP, and the other was repaired by CFRP. The second group also contained two beams, one of which was reinforced by PF, and the other was repaired by PF, while the fifth beam was a control beam. From the experimental results, a significant increase in the ultimate load of the beams reinforced by PF or CFRP ranged between 45.45 and 51%, respectively. This is due to the role of manufactured PFs and CFRP in restricting the width of cracks in the bending zone of reinforced or repaired concrete beams. Also, there was a change in the type of failure when changing the type of fiber, where the failure was ductile and gradual in the beams reinforced or repaired with manufactured PFs, unlike what was in the beams reinforced or repaired by CFRP, where the failure was brittle and sudden.
The establishment of a performance evaluation model using education informatization to evaluate teacher morality construction in colleges and universities
Authors: Hou Weiwei 
Published: May 2024

Abstract
To improve the effectiveness of the construction of teacher morality in colleges and universities, this article employs the performance evaluation model of education informatization to construct an evaluation system for the construction of teacher morality in colleges and universities. The evaluation of the construction effect of teacher morality is carried out through intelligent data analysis, and the significant error is used as the parameter of the teacher’s morality to make estimations. Moreover, a binary variable is introduced to judge whether the data have a significant error. Mixed integer linear and nonlinear programming methods are employed to detect significant errors. In addition, the idea of synchronizing teachers’ moral data is added. The effectiveness of the proposed method is verified by a simulation study using MATLAB 2017. The results show that it is necessary to establish and improve the talent flow mechanism that conforms to the requirements to promote the rational flow of teachers.
Arabicization via Loan Translation: A Corpus-based Analysis of Neologisms Translated from English into Arabic in the Field of Information Technology
Authors: Al-Athwary Anwar A. H. , Ali Husam Khaled 
Published: May 2024

Abstract
This study aims to use a corpus-based analysis to examine loan translation (LT) as an Arabicization technique in Written Standard Arabic (WSA) for information technology (IT) and investigate the factors impacting LT formation. Data were collected from four corpora: four Arabic online newspapers, the Microsoft Language Portal, two user manuals, and the Arabic Corpus of King Abdul-Aziz City for Science and Technology (KACST). Four LT strategies were identified: morphosyntactic pattern alteration, literal translation, loan blending, and metaphorical extension. Literal translation occurred in three degrees: full LTs, partial LTs, and non-LTs, through calquing. Metaphors based on functional similarity played a crucial role in understanding and accepting IT terms in WSA. Paradigmatic variation prevailed in LTs, with synonymous variations more common than nonsynonymous ones, and no syntagmatic variation. The KACST analysis showed significant differences in occurrence frequency among LT variants. LT formation and variation were influenced by linguistic factors such as lexical need, semantic transparency, and lexical borrowing, as well as extralinguistic factors such as nationalism and lack of coordination among Arabic language academies. The study concludes with implications for addressing the absence of coordination between these academies and improving IT-related LT quality between English and WSA.

Abstract

Objectives
This work was carried out with a view to determining the antioxidant, anti-inflammatory and anti-ulcer properties of the aqueous lyophilized extract of Markhamia lutea.

Methods

In vitro proteinases inhibition, albumin denaturation, hemolysis of red blood cells by heat, inhibition of the proton pump H+/K+ATPase, FRAP (Ferric reducing antioxidant power) and DPPH (1,1-diphenyl-2-picrylhydrazyl) assays were performed. In vivo, cold water immersion-induced ulceration and methylene blue-induced ulceration was used to determine the anti-ulcer properties of the lyophilizate (100, 200 and 300 mg/kg).

Results

In vitro, the lyophilizate (400 μg/mL) significantly inhibited protein denaturation (66.65 %), hemolysis of red blood cells (56.54 %), proteinase activity (69.22 %); then the IC50 was 26.31 μg/mL on proton pump activity. It has also developed a strong ferric reducing antioxidant power (EC50=52.96 mmol FeSO4/g) as well as free radicals scavenging activity (EC50=22.38 μg/mL). In vivo, the aqueous lyophilizate (200 and 300 mg/kg) protected the gastric mucosa (70.68 and 79.00 % protection respectively) and reduced (p<0.05) acetylcholine, calcium and corticosterone concentrations. A decrease in malondialdehyde level, an increased glutathione level and an increased in catalase and SOD activities were recorded. In the methylene blue test, it significantly increased gastric fluid pH, while reducing gastric volume and improving hematological parameters in ulcer animals. In addition, the histological sections show that the aqueous lyophilizate of M. lutea protected the gastric mucosa from the deleterious effects of stress.

Conclusions
The aqueous lyophilizate of M. lutea has anti-ulcer properties thanks to its anti-inflammatory, antioxidant and anti-secretory properties.
High STAT4 expression correlates with poor prognosis in acute myeloid leukemia and facilitates disease progression by upregulating VEGFA expression
Authors: Li Aohang , Wu Jingxuan 
Published: May 2024

Abstract
The aim of our study is to explore the mechanism of transcription-4 (STAT4) in acute myeloid leukemia (AML). STAT4 level in AML bone marrow samples/cells was analyzed using bioinformatics and quantitative real-time PCR. The correlation between high STAT4 expression and the prognosis of AML patients was analyzed. The viability, apoptosis, and angiogenesis of AML cells were detected. The levels of STAT4, vascular endothelial growth factor A (VEGFA), and apoptosis-related proteins (Bcl-2 and Bax) in transfected AML cells were examined. STAT4 level was upregulated in AML. STAT4 silencing decreased the viability and angiogenesis, yet increased the apoptosis of AML cells, while overexpressed STAT4 did conversely. VEGFA silencing counteracted the impacts of overexpressed STAT4 upon promoting viability and angiogenesis as well as repressing the apoptosis of AML cells. High STAT4 expression was correlated with poor prognosis of AML patients and facilitated disease progression via upregulating VEGFA expression.
Complexity trade-off in morphosyntactic module: suggestions from Japanese dialects
Authors: Li Wenchao , Liu Haitao 
Published: May 2024

Abstract
Using the GiNZA v4 natural language processing library, this study examines the case marking richness and word order flexibility in Japanese dialects across 47 regions to investigate the dynamic self-adaptation within the language subsystem, specifically morphology and syntax. Case marking richness is evaluated using the moving-average mean size of paradigm, while word order flexibility is assessed through entropy. The findings reveal a positive correlation between case marking richness and word order flexibility, providing empirical support for the “complexity trade-off hypothesis”. Leveraging the distinct morphosyntactic features inherent in dialects, this study proposes a hypothesis for categorizing Japanese dialects.

El desarrollo de capacidades relacionadas con el uso y aprovechamiento de las Tecnologías de la Información y las Comunicaciones – TIC, en el ámbito educativo ha sido ampliamente abordado desde lineamientos de política pública e iniciativas de orden público y privado, sin embargo, llegar a resultados que impacten todas las zonas geográficas de Colombia, ha sido un reto que aún no ha sido superado. En este escenario, el programa AlfaTIC liderado por la Corporación Centro de Ciencia y Tecnología de Antioquia – CTA y financiado por la Fundación Fraternidad Medellin tiene como objetivo contribuir al desarrollo de las prácticas pedagógicas de los docentes en Instituciones Educativas Rurales de las subregiones del Oriente, Suroeste y Urabá Antioqueño con el fin de fortalecer habilidades y competencias digitales que aporten al cierre de la brecha digital. De las competencias propuestas por el MEN (2013) se adoptaron para el presente proyecto tres de ellas, pedagogica, tecnologica y comunicativa, con sus respectivos niveles de desempeño. Para el año 2022 la prueba evidenció un alto porcentaje de docentes en niveles de integración e innovación, sin embargo, es importante resaltar que se trata de estados iniciales de apropiación y aplicación de la tecnología en educación. Por lo tanto, la investigación destaca la importancia de integrar competencias pedagógicas, comunicativas y tecnológicas en la enseñanza con TIC. De igual forma, propone identificar líderes educativos para guiar y capacitar a docentes, fomentar la colaboración entre ellos, garantizar la participación de todos en programas de formación, fortalecer la evaluación continua, tomar como referencia instituciones innovadoras, facilitar redes profesionales, proporcionar apoyo constante y mantener programas flexibles y adaptables. La propuesta incluye seguimiento y evaluación periódica del desempeño docente, vinculando resultados de aprendizaje estudiantil.
La inminente reforma del sistema jurisdiccional de la Unión Europea
Authors: Kühn Baca Werner Miguel 
Published: May 2024

El Tribunal de Justicia de la Unión Europea (“TJUE”) ha solicitado una modificación de su Estatuto para hacer frente a los retos derivados de una carga de trabajo cada vez mayor. El objetivo es redefinir la competencia de los órganos jurisdiccionales de la UE con el fin de permitirles seguir cumpliendo, en un plazo razonable, la misión que les han asignado los redactores de los Tratados en el artículo 19, apartado 1, del Tratado de la UE (“TUE”), a saber, garantizar que “en la interpretación y aplicación de los Tratados se respete el Derecho”. La reforma prevé concretamente una transferencia parcial de las competencias interpretativas al Tribunal General (“TG”), combinada con la facultad del TJUE de tratar asuntos de especial relevancia. Además, la posibilidad de interponer un recurso ante el TJUE se limitará si las salas de recurso de las agencias de la UE ya han llevado a cabo una revisión jurídica en primera instancia. Una serie de salvaguardias evitarán una situación en la que el reparto de la carga de trabajo por dos órganos jurisdiccionales distintos pueda tener un efecto negativo en la uniformidad y coherencia de la jurisprudencia.

The annual pelagic fish landings of the country comprising diverse species, increased from0.3 million t in 1950 to >3 million t in 2021, marking a tenfold increase. The pelagic resourcesconsistently constituted over half of the total marine fish landings. Major contributors tothe pelagic landings are sardines, mackerels, tunas, carangids, ribbonfishes, Bombayduck,codlets, billfishes and barracudas. The west coast of India accounts for 60% of total pelagiclandings with the south-west coast comprising of Kerala, Karnataka and Goa sustainingvast shoals of small pelagic fishes thriving in the nutrient-rich upwelled waters. The pelagicfishes play a crucial role in the marine ecosystem, functioning as both prey and predator.Furthermore, the small pelagic fishes serve as sources of protein-rich food for coastalpopulations, and the large pelagic species command lucrative market prices both in thedomestic and export markets. Continuous monitoring of the landings of pelagic fishes isessential for recommending suitable management plans for the optimal and sustainableexploitation of the available pelagic resources in Indian waters. This paper attempts toprovide an overview of the marine pelagic fisheries of India, based on analysis of the fishlandings data across various sectors spanning the period from 1985 to 2021.

Optimization of a novel hybrid photo-ozonation peroxymonosulfate process for degradation of Acid Black ATT dye in aqueous environment
Authors: Majlesi Monireh , Rahmati Seyedeh Hoda , Alipour Arash , Dolatyari Atousa , Hashemi Marjan 
Published: May 2024

Abstract

The current research aimed to simultaneously generate sulfate and hydroxyl radicals to break down Acid Black ATT dye. It was observed that using UV radiation and ozonation separately is insufficient for the complete decomposition of this dye compound. Based on the results, the UV/O3/PMS process is able to completely remove all dye concentrations under the optimum conditions (pH=10, O3=20 mg/min, PMS=0.4 mM L-1, and AB-ATT=20 mg/L) in 10 minutes, with significant removal of TOC and COD. For every 0.1 mM increase in PMS concentration, dye removal increased by 14 %. Hydroxyl and sulfate radicals were identified as the primary active species responsible for the degradation. The degradation followed first kinetic order, and hydroxylation and decarboxylation pathways were found to contribute significantly to the process. Therefore, the combined UV/O3/PMS process can be used as an environmentally friendly hybrid technology of advanced sulfate-based oxidation to remove recalcitrant contaminants from aqueous solutions.

Abstract

This study aimed to evaluate the distribution and mobility of trace metals (Pb, Cu, Cd, Cr, Ni, Zn) in surface soils of Pernambuco state, Northeast Brazil, applying sequential extraction techniques defined by the Community Bureau of Reference (BCR) and complemented by statistical analysis through Principal Component Analysis (PCA) and Pearson correlation matrix. Analysis of fifty topsoil samples showed that most metals predominantly reside in the residual fraction. However, Cd, Ni, and Zn were significantly present in the mobile fraction. Cd and Pb were closely associated with iron and manganese oxides, indicating their potential mobility within environmental matrices. Cu, however, was primarily detected under oxidising conditions in the residual fraction. PCA revealed a positive correlation of soil pH with Ni, Cu, and Cr and a negative correlation with Zn, Cd, and Pb. Factors such as organic matter and soil texture also play significant roles in influencing the mobility of these metals. The study highlights significant variances across different soil classes, underscoring the complex nature of soil chemistry. These findings emphasise the importance of sequential extraction and PCA in assessing metal solubility and availability, which is crucial for effective environmental management and agricultural practices.
