Authors: Hanifa Dea Aurellia , Agustina Laelatus Syifa Sari
Published: February 2025

Massively using the internet that exists today turns out to have a negative impact, such as the emergence of cyberbullying behavior. One of the factors that can influence the emergence of cyberbullying intentions is self-efficacy, this can occur due to a lack of belief in the ability of the self (self-efficacy) that individuals have which can lead to the intention of this behavior. This study aims to determine the relationship between self-efficacy and the intention of cyberbullying behavior in adolescents. There were 349 respondents collected through accidental sampling technique. The measuring instrument used in this study is the General Self-Efficacy Scale (GSES) to measure self-efficacy variables and the Cyberbullying Intention Scale to measure cyberbullying behavior intention variables. The results showed that there was a significant negative correlation between self-efficacy and cyberbullying behavior intention with a correlation coefficient (r) -0.270 and sig 0.000 (p < 0.05). This means that the higher self-efficacy, the lower intention of cyberbullying behavior will appear and vice versa.
 
Masifnya penggunaan internet yang ada saat ini ternyata menimbulkan dampak negatif, salah satunya adalah kemunculan perilaku cyberbullying. Salah satu faktor yang dapat mempengaruhi kemunculan intensi cyberbullying adalah efikasi diri, hal ini dapat terjadi karena kurangnya keyakinan akan kemampuan diri (efikasi diri) yang dimiliki individu sehingga dapat memunculkan intensi terhadap perilaku tersebut. Penelitian ini bertujuan untuk mengetahui hubungan efikasi diri dengan intensi perilaku cyberbullying pada remaja. Terdapat 349 responden yang diperoleh melalui teknik accidental sampling. Alat ukur yang digunakan dalam penelitian ini adalah General Self-Efficacy Scale (GSES) untuk mengukur variabel efikasi diri dan Skala Intensi Cyberbullying untuk mengukur variabel intensi perilaku cyberbullying. Hasil penelitian menunjukkan bahwa terdapat korelasi negatif yang signifikan antara efikasi diri dan intensi perilaku cyberbullying dengan koefisien korelasi (r) -0,270 dan sig 0,000 (p < 0,05). Artinya, semakin tinggi efikasi diri maka akan semakin rendah intensi perilaku cyberbullying yang akan muncul dan begitu pula sebaliknya.

This study aims to identify themes, trends, and networks in the mechanisms that shape the quality of investment decisions in the context of behavioural finance using bibliometric. The results show that good financial literacy can reduce the negative influence of cognitive biases such as heuristics, framing effects, and herd mentality in investment decision-making. In addition, improved financial literacy also plays a role in moderating the effects of behavioural biases on investment decisions, resulting in more rational and profitable decisions. Therefore, financial literacy is an effective strategy to improve the quality of investment decisions by reducing the impact of cognitive biases.

Dort schafft man die Kronjuwelen fort ... Objekt-Perspektiven auf die 1848er Revolution
Authors: Georgiev Anna
Published: February 2025

Dass die Einbeziehung von materiellen Gesichtspunkten in die Analyse von historischen Ereignissen neue Aspekte in der Betrachtung derselben aufdecken kann, wird in dem vorliegenden Aufsatz anhand der Sicherung der Wertbestände am preußischen Hof während der Revolution 1848/49 aufgezeigt. Grundlegend ist diesbezüglich zwischen dem Staatsschatz sowie den Vermögen der Krone bzw. des königlichen Hauses zu unterscheiden. Anhand vielfältiger Stellungnahmen aus dem Umkreis des Hofes lassen sich Einzelheiten der Verbringung dieser Vermögen aus Berlin unter höchster Geheimhaltung rekonstruieren. Der damalige Prinz von Preußen – Bruder Friedrich Wilhelms IV. und späterer Kaiser und König Wilhelm I. – sah sich im Zuge der Zuspitzung des revolutionären Verlaufs genötigt, nach England zu reisen. Die Überführung auch der Kronjuwelen folgte. Im Zuge der Stabilisierung der politischen Lage kehrten diese vermutlich im Folgejahr nach Preußen zurück. Die letztwillige Verordnung Friedrich Wilhelms IV. vom April 1849 bald nach der Kaiserdeputation gibt weiterführende Hinweise auf die angespannte Gemütslage am Hof. Insgesamt lassen sich durch den verstärkten Fokus auf Objekte in der Darstellung nicht nur vertiefte Einblicke in die Abwägung von Handlungsoptionen durch das Königshaus in Reaktion auf die Entwicklung der Revolution geben, sondern auch aufzeigen, dass konkrete Belege für den später vorgebrachten Vorwurf der Veruntreuung zu dieser Zeit fehlen.
Investigation of gas-liquid flow hydrodynamics in the industrial-scale stirred tank with inclined impeller
Authors: Yuan Haibin , Yang Shiliang , Lai Kui , Xu Wanli , Tang Duzuo , Yang Bin
Published: February 2025

The inclined-axis stirring system is widely employed in industrial processes due to its exceptional mixing capabilities, ease of industrial retrofitting, and commendable safety and stability features. This study numerically investigates the multiphase flow characteristics within an industrial-scale inclined-axis stirring tank, utilizing the realizable k-ε model and the volume of fluid model. With the validated model, the impact of impeller rotational speed on the flow characteristics in the stirred tank is explored. The findings reveal several noteworthy observations: As the stirring speed increases, liquid level fluctuations intensify. At excessively high stirring speeds, a large number of bubbles are entrained and dispersed into the stirring tank. Multi-scale vortices are observed within the inclined-axis stirred tank. Notably, two relatively large-scale vortices manifest on either side of the rotating blade. Comparatively, the tilted arrangement of the stirring shaft disrupts the symmetry of the flow field. Regions beneath the blades and at the bottom of the stirred tank exhibit elevated liquid phase velocities, radial velocities, and axial velocities. The rising area of the fluid in the stirred tank is near the wall, forming a ring shape, while the center of the ring is characterized by descending fluid. These findings provide valuable theoretical insights for the structural configuration and considerations related to energy conservation in industrial agitation equipment.

Authors: Marinho Aline Diogo , Braz Helyson Lucas Bezerra , de Moraes Silveira João Alison , Rocha Danilo Galvão , Jorge Roberta Jeane Bezerra , de Andrade Geanne Matos
Published: February 2025

Background:

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first identified in China in December 2019, rapidly spread worldwide, resulting in the coronavirus disease 2019 (COVID-19) pandemic. Understanding the structural and functional interactions between the virus and host cells is critical for developing therapeutic strategies.

Methods:

In this study, we employed in silico docking models to investigate the molecular interactions between the receptor-binding domain (RBD) of the SARS-CoV-2 spike glycoprotein, derived from the Brazilian genome sequence, and seven clinically approved drugs: umifenovir, darunavir, lopinavir, ritonavir, remdesivir, pirfenidone, and oseltamivir. The three-dimensional structure of the Omicron RBD model was generated through homology modeling, and potential active site cavities were predicted within the RBD structure.

Results:

Among the seven drugs tested, only lopinavir and ritonavir demonstrated significant binding affinities to the RBD. Lopinavir exhibited a binding affinity of −9.8 kcal/mol, forming interactions with residues PHE168, GLY167, SER176, GLN175, GLU166, LEU134, LEU137, TYR171, PHE138, LEU174, and PHE172. Ritonavir showed a binding affinity of −8.9 kcal/mol, interacting with residues ARG148, ASN130, VAL23, SER81, ASN33, PHE29, TYR33, SER31, ASN132, ALA26, ALA30, ALA34, and TYR133.Molecular dynamics simulations confirmed the stability of the complexes formed between lopinavir and ritonavir and the RBD active site.

Conclusion:

These findings underscore the potential of these protease inhibitors as therapeutic agents targeting the SARS-CoV-2 spike protein.
Ovarian function in adolescents and young adults undergoing cancer treatment: biochemical and ultrasound marker analysis
Authors: Signorino Claudia , Bencini Erica , Tondo Annalisa , Scalini Perla , Tamburini Angela , Casini Tommaso , Sardi Iacopo , Stagi Stefano
Published: January 2025

Objective

Gonadal dysfunction is a major late complication after cancer diagnosis and treatment. We aimed to study the prevalence of premature ovarian insufficiency (POI) and the potential reduction of ovarian reserve in a cohort of adolescent and young adult (AYA) patients undergoing cancer treatments, evaluating ovarian function and reserve markers. We also aimed to analyze how these markers are related to each other and to treatment-related risk factors.

Methods

We performed a retrospective study, including all female AYA patients undergoing cancer treatment during childhood or adolescence, who visited our pediatric gynecology outpatient clinic between January 1, 2018, and August 30, 2023. Serum levels of anti-Mullerian hormone (AMH) and follicle-stimulating hormone (FSH), antral follicle count (AFC) and mean ovarian volume were evaluated. The correlations between these markers and how their alterations are related to treatment-related risk factors were analyzed.

Results

The prevalence of POI in 95 patients was 18.9%. A significant positive correlation was observed between AMH levels and both AFC and ovarian volume. AMH was the most reliable serum marker for ovarian function in terms of POI. Independent risk factors for ovarian dysfunction in relation to all the markers analyzed were hematopoietic stem cell transplantation (HSCT) and high doses of alkylating agents (≥6000 mg/m2).

Conclusion

Gonadal dysfunction and infertility are quite common in AYA patients undergoing cancer treatment. High-dose alkylating agents and HSCT are the independent risk factors. AMH and FSH values, AFC and mean ovarian volume provide different but consistent information for closely monitoring patients after cancer treatment.
Neural correlates of social feedback from friends and self-reported happiness in adolescence
Authors: Breiner Kaitlyn , Galván Adriana
Published: January 2025

Adolescence marks a period of development characterized by increased time spent with friends and learning how to navigate social relationships from feedback received from peers. Research suggests that frontolimbic circuitry, which undergoes significant development during adolescence, helps adolescents learn by encoding feedback. To test this theory, previous studies have given adolescents feedback via someone unknown to them. Understanding how adolescents respond when receiving social feedback from a friend is critical as they engage with friends to help form opinions of themselves. For this reason, we created an ecologically valid task asking adolescents questions about their friendships and showing them responses purportedly provided by their friend.

This study used functional magnetic resonance imaging (fMRI) and a novel Friendship Feedback Task programmed using E-Prime 2.0 to leverage real-life social expectations between 26 adolescent participants (53.8% girls, ages 14-17, M= 15.81, SD= 1.02) from the USA. Participants were presented with positive or negative statements about their friendships with another adolescent while undergoing an fMRI scan. Following the scan, participants were asked how happy they felt when they received social feedback about their friendship.

Results: Adolescents reported feeling happier when social expectations were met compared to when they received positive and negative social feedback. Regions of Interest (ROI) analyses revealed increased ventral striatum activation as expectations were met, greater ventral striatum activation during positive versus negative social feedback; and greater insula and subgenual anterior cingulate cortex activation during negative versus positive social feedback.

These results suggest positive and expected social information engages frontolimbic circuitry previously implicated in reward, while unexpected social information elicits neural circuitry previously implicated in non-social learning in adolescents. This study demonstrates that during adolescence, friends provide important social information, and when the information received is unexpected, it may disrupt the cognitive harmony a teenager has regarding their friendship.

Press coverage of the trial of Max Ditmar, Karl Kindermann and Theodor Wolscht in 1925 in the press of the Ukrainian SSR
Authors: Kolomoets O. Yu. , Kolomoets Yu. I.
Published: February 2025

The paper deals with the process of coverage of the trial of Max Ditmar, Karl Kindermann and Theodor Wolscht in the press of Soviet Ukraine in 1925. The openness of the trial was intended to show the objectivity of the USSR judicial system and send a signal to Germany about the possibility of a mutual exchange of the convicts. The confessions of the defendants, given by them during the investigation and voiced in the courtroom, compensated for the obvious insufficiency of the evidence base. They confessed to making plans of terrorist acts against the top leadership of the USSR, the intention to find out the connections of the German Communist Party with the Comintern, plans for economic espionage. Regular court reports were published. Moscow correspondents reported their impressions of the behavior of the defendants, creating unsightly images of typical agents of the bourgeoisie, both mediocre and filled with hatred of the working class. Kindermann and Wolscht were contrasted by the repentant Ditmar, whose demeanor was described as courageous and upright. However, this did not affect the death sentence imposed on all three defendants. The reaction of the German press to the trial was covered. Newspapers emphasized the efficiency of the actions of the state security agencies and the vigilance of ordinary employees. Full coverage and prompt informing of residents of different regions and representatives of different social groups (peasants, workers, military personnel) were achieved by involving the maximum number of newspapers to propaganda campaign. The paper shows that the information campaign launched in the regional press was aimed at showing the Soviet reader the reality of the constant threat to the Soviet state from the world bourgeoisie. Also, the press tried to form the reader’s conviction that his personal vigilance is an important part of the state security system.

Published: January 2025

For a better understanding of the factors involved in biological sewage treatment and the importance of the planktonic community in stabilization ponds, this research evaluated the functioning of a domestic sewage treatment system, considering pollutant removal, with special attention to the planktonic community. The system was composed of an up-flow anaerobic sludge blanket reactor and a full-scale submerged aerated biofilter, followed by a series of four pilot-scale polishing ponds. The following variables were studied: transparency, temperature, dissolved oxygen, pH, alkalinity, biochemical oxygen demand, chemical oxygen demand, total suspended solids, and chlorophyll-a, besides precipitation and air temperature. During the study period, the planktonic community was represented by 103 taxa, divided into seven classes: Chlorophyceae (51.5 %), Euglenophyceae (20.4 %), Cyanobacteria (17.5 %), Cryptophyceae (5.8 %), Zygnemaphyceae (1.9 %), Chrysophyceae (1.9 %) and Dinophyceae (1 %). The minimum and maximum values of the total planktonic count were 2647 cells/mL in Pond three and 151,357 cells/mL in Pond one. The high concentrations of microalgae and cyanobacteria increased the total suspended solids. The zooplankton community was represented by Rotifers, Copepod, and Cladocera, which were found at low densities, with total values ranging from 310 org/mL in Pond one to 2436 org/mL in Pond two.

Published: January 2025

Actividades antropogénicas como la deforestación y los incendios generan pérdida de biodiversidad a nivel mundial. Ecuador es considerado un país megadiverso con 25000 especies de plantas, entre las que destacan los helechos. Sin embargo, este grupo de plantas el estudio de su diversidad y estado de conservación es limitado para la mayoría de las áreas naturales del país. En este estudio se realizó un inventario y se evaluó el estado de conservación de helechos y licofitas en la Estación Experimental La Favorita, ubicada en el occidente de Ecuador. Se muestreó y registro datos biológicos de especímenes en lugares que no se observó perturbaciones antropogénica o ecológica reciente, mediante cuadrantes de 20x20 m. Utilizando el software PAST 3,2 se calcularon los índices de diversidad de Margalef, Simpson y Shannon – Wiener. Se obtuvo un alto rango de diversidad en el bosque nativo. El índice de Sorensen determinó un 96,67 % de similitud de helechos y licofitas compartido entre el bosque nativo y el bosque de eucaliptos. Se contabilizaron un total de 6013 especímenes, pertenecientes a 32 especies. Mediante una adaptación del índice SUMIN se evaluó el estado de conservación, siendo las especies Tectaria pilosa, Adiantum patens y Pteris muricata las que presentan mayor prioridad de conservación, mientras que las especies: Alsophila erinacea, Equisetum bogotense y Blechnum polypodioides se consideraron de atención especial, al presentar una considerable disminución de individuos o la ausencia en uno o más tipos de bosque.

Published: January 2025

Se abordan los documentos en español de empresas tecnológicas que explican y promocionan productos del Procesamiento del Lenguaje Natural (componente de la Inteligencia Artificial que estudia cómo las computadoras procesan el lenguaje humano), tales como sistemas de transcripción, uso de chatbots, traducción automática. El objetivo es analizar qué consideraciones lingüísticas priman en estos documentos y qué fenómenos del lenguaje deben ser regulados para un buen funcionamiento del PLN. El trabajo se inscribe en un enfoque glotopolítico, perspectiva que analiza las distintas intervenciones sociales sobre el lenguaje. Sobre un corpus conformado por los documentos de seis compañías, se estudian tanto los ideologemas y las representaciones sociolingüísticas, como la dimensión enunciativo-argumentativa. Se mostrará que la recurrente caracterización del lenguaje a partir de su complejidad opera discursivamente para justificar las limitaciones del PLN; y que resultan categorizados como «irregularidades» una serie de fenómenos muy disímiles entre sí en cuanto a su naturaleza lingüístico-discursiva, que involucra tanto aspectos semántico-polisémicos como discursivo-polifónicos, pero que también incluye el uso de recursos retóricos y de variedades lingüísticas.
Effect of the SARS-CoV-2 viral load on hematological and biochemical parameters
Authors: Caires Neves Magalhães Gustavo , Moura Gomes Clayson , Do Prado Assunção Leandro , Henrique Nascente Costa Sérgio , Antônio Vinhal dos Santos Fernando , Correia de Alcântara Keila
Published: January 2025

Objective: the viral load is determined by the cycle threshold (Ct), which is inversely proportional to the amount of target sequences present in the sample. In various viral diseases, the induction of inflammatory cytokines is strongly correlated with the viral load. However, the viral kinetics of SARS-CoV-2 remain poorly characterized, and its association with disease progression remains controversial. This study aimed to understand the correlation between the SARS-CoV-2 viral load and the biochemical and hematological markers in COVID-19-positive patients.
Methods: data from patients with detectable viral load for SARS-CoV-2 treated between March 2020 and May 2021 were collected between Jan/2023 and Jan/2024. Data were analyzed using Pearson's correlation, Student's t-test, and analysis of variance.
Results: the mean Ct values for the N and ORF1AB genes were 26.73 (±3.95) and 25.93 (±4.75), respectively. A Ct value below the mean for the N and ORF1AB genes, suggesting a higher viral load, was observed in 17.8% (n=152) and 18.4% (n=157) of the patients. There was no correlation between the mean Ct and hematological or biochemical parameters, but the monocyte-to-lymphocyte ratio (MLR) was below the reference value for COVID-19-negative patients (P<0.0001). The C-reactive protein and ferritin levels were higher in patients with COVID-19 (P<0.05). Leucopenia (P<0.001), lymphocytopenia (P<0.001), neutropenia (P<0.001), and thrombocytopenia (P=0.003) were observed more frequently in patients with COVID-19.
Conclusion: the MLR below the reference value was more frequent observed in patients with a higher Ct value (lower viral load).
Navigating the mainstreaming of psychedelics
Authors: Labate Beatriz Caiuby , Antunes Henrique Fernandes , Beachy Jamie , Sloshower Jordan , Cavnar Clancy
Published: January 2025

This article critically addresses one of the most pressing questions of the current moment of the psychedelic wave: Is mainstreaming psychedelics a good thing? Our aim is not to provide a simple “yes” or “no” as an answer but to explore the tensions, controversies, disparities, inequalities, and risks that have risen in the last decades. We discuss the limits of psychedelic science as the paradigm leading this movement and the risks of an overemphasis on biomedicalization to the detriment of the social sciences, humanities, and traditional knowledge. We also examine policy considerations, the dangers of commodification, and the ecological burdens that the expansion of the use of psychedelics is causing. Additionally, the article reflects on the tendency to prioritize the psychotherapeutic approach to care, a topic that has been neglected in the field. The authors put forward the need for inclusion, ethics, and reciprocity to balance the inequalities that risk recreating the psychedelic movement as another expression of mainstream capitalist endeavors. Given the Food and Drug Administration's delay in approval of MDMA for PTSD and the hurdles for regulating access to psychedelics in ceremonial and therapeutic contexts, such as Colorado and Oregon, there is an urgent need to engage in an informed conversation about the future of the psychedelic movement. It is important to avoid the tendency to romanticize this landscape and to do a proper assessment of the contemporary challenges and ethical risks that we face in the future.

The Glorious Teachers of Vikramshila
Authors: Mishra Reeta
Published: January 2025

Vikramshila calls for resuscitation, for the past eight centuries. There had been a division of opinion regarding its correct location, but there was no difference regarding its fame and effulgence. Like a bright diamond, it shines even amidst rebels. Now the location is proven through excavations. From Taranaths’s account, the greatest probability was at Colgong and not at Silao. S. C. Das and a host of others were inclined to accept it near Patharghata hills at Colgong, a few kilometres east of Bhagalpur, where the Ganges, takes a northerly turn and where Taranath’s descriptions proved accurate. But history is no more sheer worship of Cleo, it is also the time endeavouring to be exact. The truth about Vikramshila lies hidden in the womb of Mother Earth: to the industrious researcher she is whirling to unveil herself, this excavation adds one more feather to the cultural heritage, of which India has an inexhaustible store, ready to reveal herself in her finest glories and glorious teachers.

Анотація. У статті наведено аналіз стабільності кількісно-якісних результатів помелів за розширеною системою оцінки показників якості. Проаналізовано якість 20 помельних партій зерна пшениці та 40 зразків борошна, з яких 20 – борошно вищого сорту та 20 – борошно першого сорту.
Встановлено, що найбільша мінливість якості у досліджуваних зразках характерна саме для показника число падіння (ЧП), який змінювався у межах 240-370 с – у зерні, 309-477 с – у борошні вищого сорту та 300-456 с – у борошні першого сорту. Стабілізація та контроль показника ЧП дозволить отримувати борошно зі стабільними характеристиками альфа-амілолітичної активності.
Вміст та індекс деформації клейковини є «традиційними» вітчизняними показниками оцінки хлібопекарської якості борошна. Однак, в реаліях сьогодення цих показників для комплексної оцінки хлібопекарських властивостей сортового борошна недостатньо. Тому все частіше хлібопекарі приділяють увагу показнику енергії деформації або «сила борошна» (W). Показники альвеографічного дослідження борошномели всього світу використовують для аналізу та оптимізації якості борошна відповідно до специфікацій замовника. В Україні показник «сила борошна» входить лише у перелік некласоутворювальних показників якості зерна пшениці м'якої згідно з ДСТУ 3768:2019, стандарт ГСТУ 46.004-99 не обмежує якість борошна за цим показником, одним з головних сортоутворюючих показників є вміст клейковини.
В результаті порівняння показників хлібопекарської якості борошна, які визначаються за вітчизняними методами (вміст клейковини та ІДК) та за зарубіжними методами (енергія деформації W та коефіцієнт конфігурації P/L) у сортовому борошні зроблено висновок, що прямого взаємозв’язку між вмістом клейковини і показником енергії деформації W, індексом деформації клейковини ІДК і показником P/L не спостерігається. З отриманих результатів видно, що традиційних показників для оцінки хлібопекарського потенціалу борошна недостатньо. Сучасна якість борошна в конкурентних умовах вимагає від виробника забезпечення необхідної «сили борошна» для конкретних груп хлібобулочних виробів.

Sirtuins (SIRTs) are key regulators of cellular metabolism, involved in a wide range of physiological and pathological processes. However, there is scarce knowledge about the effect of sugar consumption and physical activity on SIRTs in kidney disorders. Here, we evaluated the impact of prolonged consumption of an isocaloric high-sugar diet (HSD) and physical training on the modulation of renal Sirts and the link between these alterations and possible obesity-associated kidney damage. Newly weaned male Wistar rats were fed a standard chow diet (STD) or HSD ad libitum and then subjected or not to regular workload swimming training for 18 weeks. Morphometric and biochemical parameters were analyzed, and the kidneys were removed for lipid quantification, histological analysis, and for Sirts1-7 expression. HSD led to the development of obesity, increased serum triglyceride levels, and glucose intolerance, regardless of higher caloric consumption. However, training was able to partially inhibit the HSD-induced obesogenic effect. No changes were identified in kidney mass, lipid content, histology, and creatinine clearance among the groups; these results were associated with a decrease in the renal expression of Sirt2-3 and Sirt7; however, training was able to reverse this modulation. The interaction between HSD and training led to an increase in Sirt4-7. However, Sirt1 remained constant among experimental groups. In conclusion, our results indicated that the transcriptional modulation of Sirts precedes HSD-induced damage and loss of kidney function, as well as a possible protective adaptive response of physical exercise on long-term Sirts expression.
Ultimate load of Steel Fiber Reinforced Concrete (SFRC) encased light gauge steel column exposed to elevated temperature using computational model approach

Published: January 2025

ABSTRACT This research emphasizes the critical role of fire resistance in building structures, with a particular focus on concrete columns, which are vital for maintaining structural integrity during fires. Concrete Encased Steel (CES) columns, featuring steel sections encased in concrete, provide improved ductility, shear strength, and compressive capacity. While the fire-resistant properties of Concrete Filled Steel Tubular (CFST) columns have been widely studied, CES columns are increasingly recognized for their unique advantages. A key research gap exists in predicting the ultimate load of Steel Fiber Reinforced CES columns under elevated temperatures. This study addresses the gap by developing a computational model using Machine Learning (ML) techniques. Forty CES columns, subjected to various conditions such as different concrete types, temperatures, and encasement were experimentally tested. The data was used to train ML algorithms, including Linear Regression (LR), Extreme Gradient Boosting (XGB), Gradient Boost Regressor (GBR), and Voting Regressor (VR), to predict the ultimate load under high temperatures. The model's performance was assessed using R2, RMSE, MSE, and MAE metrics, with XGB outperforming other models by achieving an R2 value of 0.94, indicating excellent predictive accuracy.

Objective: to verify the internal and structural consistency of the Ambivalent Sexism Inventory in young undergraduate nursing students. Method: this is a cross-sectional methodological study carried out with young university students enrolled in the undergraduate Nursing course at a public university. Data was obtained by means of a sociodemographic/academic questionnaire and the Ambivalent Sexism Inventory. The analysis used Pearson’s correlation, Cronbach’s alpha, intraclass correlation, t-test and chi-square ratio and degrees of freedom, as well as confirmatory factor analysis to test the consistency of the existence of the bifactor model. Results: the sample consisted of 305 undergraduates. The oblique bifactor model showed statistical indicators that justify the consistency of the bifactor structure of sexism in the study’s target population. In addition, the psychometric indicators of the inventory showed satisfactory results. The predictive regression analysis confirmed the structure, demonstrating its consistency and robustness for assessing both hostile sexism and benevolent sexism among young university nursing students. Conclusion: support for the theory of ambivalent sexism was identified, reflecting the consistency of the oblique bifactor model. The analysis of the psychometric properties of the inventory, including validity and reliability, reinforces its applicability and relevance in research on gender issues in the health area.

Abstract Abiotic factors play a crucial role in the productivity of agricultural systems, and stress resulting from these factors can significantly restrict crop yields. To address this challenge, the use of tools capable of mitigating adverse effects, such as growth-promoting bacteria, is essential. This study aimed to investigate the growth of maize plants inoculated or not with Azospirillum brasilense, subjected to variations in soil pH and moisture. Two experiments were conducted under controlled conditions, in which maize plants inoculated with A. brasilense were subjected to variations in (i) soil moisture (100, 75, 50, and 25% of field capacity) and (ii) hydrogenic potential (pH 4.5; 5.5; 5.0; 6.0; and 6.5). It was observed that low moisture favored root growth but limited the development of leaves and stems of maize plants at the V4 phenological stage. The increased root development provided by A. brasilense under conditions of water restriction resulted in a reduction in water use efficiency by the leaves. Additionally, more acidic and/or alkaline pH levels also reduced the dry mass of roots and aboveground parts, as well as the carboxylation efficiency of rubisco, but increased water use efficiency (At 25% FC water deficit, WUE increased by 9.5% in rhizobacterium-treated seeds and by 16% in the control). Inoculation with A. brasilense promoted greater development of maize plants, as evidenced by increased volume, root length, and leaf area. Although maize plants showed better initial development without water restriction and in soil with a pH of 5.9, A. brasilense allowed maize plant growth even at pH 5.1, without significant adverse impacts.
Assessing the antioxidant potential and antibacterial properties of pomegranate peel extracts from Wonderful and Valenciana varieties

Abstract Recent studies have found a high content of polyphenolic compounds in the fruit produced by pomegranate trees (peel, arils, seeds, and capillary membranes). Most polyphenols are generally accepted to be potent antioxidants with anti-inflammatory properties. Pomegranate peel is considered a waste product of the human diet. This value is equivalent to 50% of the weight of the fruit, which is why we propose a comparative analysis of both its antioxidant and microbicidal activity in two of the most cultivated varieties in Mexico, Wonderful (sour) and Valenciana (sweet), to provide added value to products of the region by obtaining products of high biological value via a process of easy industrial scaling.
Inner and outer domains for Hawaiian causatives and nominalizers
Authors: Medeiros David J.
Published: February 2025

Hawaiian valency-related morphology includes a complex set of surface forms which have traditionally been understood as causatives. Despite phonological similarity among this set of forms, these have traditionally been analyzed as separate morphemes. A closer view of their distribution and argument structure suggests an analysis in which these forms are allomorphs of one underlying, valency-increasing morpheme. A similar analysis of two nominalizing forms suggests that these are also allomorphs of one valency-decreasing morpheme. In each case (causatives and nominalizers), an analysis of surface realization is presented in terms of inner (or root-selecting) and outer domains. With the analysis of causatives and nominalizers in place, corpus evidence suggests that the inner causative allomorph and inner nominalizing allomorph do not co-occur, even though co-occurrence of the inner nominalizer and the outer causative is common. This data suggests a morpho-syntactic view of word formation, according to which morphological properties result from general properties of the morpho-syntax, such as the availability of only one root-selecting position for a given root.
Khelobedu-L1 parents' attitudes towards using Khelobedu as a medium of instruction
Authors: Ramothwala Tsebo , Cekiso Madoda , Mandende Itani Peter
Published: January 2025

Learners who speak Khelobedu are taught in Sepedi because their language, Khelobedu, is classified as a dialect. Dialects are currently not accommodated in South African classrooms. The Khelobedu-L 1 learners therefore do not enjoy the constitutional and linguistic rights of being taught in their mother tongue as other learners are enjoying. Given this situation, we deemed it necessary to explore the attitudes of Kheloebdu-L1 parents towards the possibilities of using Khelobedu as a Medium of Instruction in the Foundation Phase. We conducted this study with 142 parents of Bolobedu South region, in Limpopo province. We used both quantitative and qualitative approaches and followed a case study design. Data was gathered through a questionnaire and semi-structured interviews and was analysed through descriptive statistics and thematic analysis. The results of the study revealed that Khelobedu-L1 parents embraced the use of Khelobedu as a MoI. The results also reflected that parents are wary that the use of Sepedi forces their children to follow other peoples' cultures, while suppressing theirs. In this paper, we discuss the factors that shape this attitude in parents.

Sentence-centric modeling of the writing process
Authors: Ulasik Malgorzata Anna , Mahlow Cerstin , Piotrowski Michael
Published: February 2025

Linguistic modeling of the writing process has gained in importance in recent years. Existing models, both from a linguistic perspective focusing on syntactic analyses as used in natural language processing and from writing research, are insufficient to actually linguistically explain what authors do when writing and revising. Writing is linear in time, but writers are free to move to any point in the text produced so far whenever they want, thus producing specific parts (e.g., sentences) in a non-linear fashion. However, the final product is a linear sequence of sentences. We therefore can interpret writing texts as a sentence-driven process. In this new framework, this article proposes a model of the production of sentences during writing. This sentence-centric model builds on existing considerations of transforming sequences, bursts and revisions, and takes into account aspects of linearity and non-linearity on the sentence level. We present a working implementation (available as open source software) and show which information can be gained by the resulting analyses in a small case study.
