Juan E. Jörgensen y el ejercicio de su arte en la exploración de la naturaleza
Authors: Andruchow Marcela , Paneiva Giuliana
Published: January 2025

This article examines the works that the Danish artist Juan E. Jörgensen (1883-1920) created for the Museo de La Plata (MLP) between 1909 and 1910. After a brief overview of his artistic and teaching career, we characterize and interpret his paintings. Jörgensen painted two large murals displayed in the rotunda on the upper floor of the museum, which depict landscapes of Argentine territory: La cascada de Escaba (Tucumán) and Alrededores del Volcán Tronador (Río Negro). These paintings occupied two spaces that had been left vacant due to the extreme deterioration of the preexistent murals painted by the artist Graciano Mendilaharzu, during the founding period of MLP, between 1886 and 1887. The themes of many of the works that Jörgensen produced throughout his artistic career are related to his work as a scientific illustrator on expeditions to the continental ice fields of Argentine and Chilean Patagonia; although in the case of the murals in MLP, definite connections with those trips have not been established. Nevertheless, the naturalistic and detailed workmanship of these murals, together with others distributed in the central node, incorporate such scenarios of the national territory and its geographical diversity within the Museum.
La galería de retratos de hombres y mujeres del noroeste argentino de Ernesto Soto Avendaño
Authors: Vernieri Julieta
Published: January 2025

This article analyses the sculptural group of 10 bronze heads made by the artist Ernesto Soto Avendaño, which were acquired by the Museo de La Plata (MLP) in 1936. The work first characterizes the artistic career of the author, pointing out some relationships with his theme and style choices. Since their acquisition, the heads have been displayed in the rotunda on the upper floor of the Museum building: five of them represent northern gauchos who tamed wild horses and were drovers, while the other five represent camelid-hunting natives from the same region. The artist used as models ten individuals that inhabited the provinces of Salta and Jujuy, where he had travelled to build a Monument to the Heroes of Independence in the city of Humahuaca. Several works were derived from his preliminary studies, including those produced between 1931 and 1935 that are currently on display at MLP. These sculptures were acquired in the context of the artistic nationalism of the time and the illustrative value attributed to the pieces for the enhancement of the ethnographic collections.
Is Google Gemini better than ChatGPT at evaluating research quality?
Authors: Thelwall Mike
Published: January 2025

Google Gemini 1.5 Flash scores were compared with ChatGPT 4o-mini on evaluations of (a) 51 of the author’s journal articles and (b) up to 200 articles in each of 34 field-based Units of Assessment (UoAs) from the UK Research Excellence Framework (REF) 2021. From (a), the results suggest that Gemini 1.5 Flash, unlike ChatGPT 4o-mini, may work better when fed with a PDF or article full text, rather than just the title and abstract. From (b), Gemini 1.5 Flash seems to be marginally less able to predict an article’s research quality (using a departmental quality proxy indicator) than ChatGPT 4o-mini, although the differences are small, and both have similar disciplinary variations in this ability. Averaging multiple runs of Gemini 1.5 Flash improves the scores.
Journal Quality Factors from ChatGPT: More meaningful than Impact Factors?
Authors: Thelwall Mike , Kousha Kayvan
Published: January 2025

Purpose

Journal Impact Factors and other citation-based indicators are widely used and abused to help select journals to publish in or to estimate the value of a published article. Nevertheless, citation rates primarily reflect scholarly impact rather than other quality dimensions, including societal impact, originality, and rigour. In response to this deficit, Journal Quality Factors (JQFs) are defined and evaluated. These are average quality score estimates given to a journal’s articles by ChatGPT.

Design/methodology/approach

JQFs were compared with Polish, Norwegian and Finnish journal ranks and with journal citation rates for 1,300 journals with 130,000 articles from 2021 in large monodisciplinary journals in the 25 out of 27 Scopus broad fields of research for which it was possible. Outliers were also examined.

Findings

JQFs correlated positively and mostly strongly (median correlation: 0.641) with journal ranks in 24 out of the 25 broad fields examined, indicating a nearly science-wide ability for ChatGPT to estimate journal quality. Journal citation rates had similarly high correlations with national journal ranks, however, so JQFs are not a universally better indicator. An examination of journals with JQFs not matching their journal ranks suggested that abstract styles may affect the result, such as whether the societal contexts of research are mentioned.

Research limitations

Different journal rankings may have given different findings because there is no agreed meaning for journal quality.

Practical implications

The results suggest that JQFs are plausible as journal quality indicators in all fields and may be useful for the (few) research and evaluation contexts where journal quality is an acceptable proxy for article quality, and especially for fields like mathematics for which citations are not strong indicators of quality.

Originality/value

This is the first attempt to estimate academic journal value with a Large Language Model.
Exploring Pluralistic Indian Nationalism: Aurobindo, Vivekananda, Gandhi, and Nehru in Historical Political Thought
Authors: Kundra Nakul
Published: January 2025

The article gives a snippet view of the pluralism of Indian nationalism by focusing on some of the critical views expounded by Aurobindo, Vivekananda, Gandhi, and Nehru, who significantly contributed to the intellectual, social, and political spheres of India. The ideas and actions of these national heroes played a crucial role in shaping the Indian idea of nationalism and the Indian freedom struggle. Aurobindo saw militant nationalism as a spiritual principle. Vivekananda believed in Karma, morality, and fearlessness; he laid focus on the Upanishads, the Brahma Sutras, and the Bhagavad Gita as the three primary ancient Vedanta writings, and he was an exponent of spiritual nationalism. Gandhi promoted Swaraj (self-rule), Swadeshi (native products for social development), Swadharma (to follow the best in our own religion), Satyagraha (holding fast to truth), Sarvodaya (upliftment of all), Brahmacharya (celibacy), Asangrah (non-possession), Sharirashrama (physical labor), Aswads (control of palate), Sarvatra-Bhaya-Varjana (fearlessness), and Ahimsa (non-violence). He upheld cultural nationalism. Nehru was inclined towards socialism. Socialism is an economic and political system that advocates for collective ownership and control of the means of production, aiming to create an egalitarian society by reducing inequalities and ensuring social welfare. The article reveals how diverse ideas inspired multi-dimensional Indian nationalism and laid the foundation of the Indian freedom struggle against the British Raj.

Authors: Evci Şevket , Eser Erva , Olgun Rabia , Kurt Ayça Melisa
Published: January 2025

Çalışmada, Japon bıldırcınlarının (Coturnix coturnix Japonica) yemlerine farklı oranlarda kekik yağı ilavesinin yumurta kalite parametreleri üzerindeki etkileri incelenmiştir. Çalışma, 6 haftalık yaşta 72 dişi Japon bıldırcını üzerinde gerçekleştirilmiştir ve bıldırcınlar kontrol, düşük kekik yağı (150 mg/kg) ve yüksek kekik yağı (300 mg/kg) gruplarına ayrılmıştır. Rasyona farklı oranlarda kekik yağı eklenmesinin bazı yumurta dış ve iç kalite parametreleri üzerine etkileri istatiksel olarak incelenmiştir. Yapılan tek yönlü varyans analizi (ANOVA) sonucundayumurta kabuk oranı, şekil indeksi ve sarı rengi gibi parametrelerin gruplar arasında istatiksel olarak anlamlı farklılıklar gösterdiği belirlenmiştir (P<0,05). Çalışmada elde edilen veriler, ANOVA sonrasında, Diskriminant analizi ile de incelenmiş ve grupların yumurta kalite parametreleri bakımından gruplanmaları belirlenmiştir. Diskriminant analizi sonucunda iki fonksiyon tanımlanmıştır. İlk fonksiyonda, düşük kekik grubunun diğer gruplardan belirgin bir şekilde ayrıldığı; özellikle kabuk ağırlığı ve pH bakımından farklılık olduğu belirlenmiştir. İkinci fonksiyonda ise kontrol ve yüksek kekik grupları arasında önemli ayrım tespit edilmiştir. Her iki fonksiyonda da ANOVA sonuçlarına benzer şekilde yumurta sarı rengi bakımından gruplar arasında farklılık gözlenmiştir. Sonuçlar, kekik yağının 150 mg/kg dozunda yem katkı maddesi olarak kullanılmasının yumurta kalitesini olumlu yönde etkileyebileceğini, ancak bıldırcın rasyonuna 300 mg/kg kekik yağı ilavesinin olumsuz sonuçlar doğurabileceğini göstermektedir.

Published: January 2025

This study aimed to evaluate the biochemical and nutritional profiles of three cauliflower cultivars—Valentena, Carotena, and Snow White—focusing on chlorophyll, carotenoids, anthocyanins, vitamin C, flavonoids, phenolics, and antioxidant activity. Uniform curds were harvested at 60 days post-sowing from Baratia, Dumuria, Khulna, and analyzed at Khulna Agricultural University. Valentena exhibited the highest chlorophyll content (40.06±0.39 µg/100g FW chlorophyll a, 28.98±3.35 µg/100g FW chlorophyll b), superior lycopene (8.71±0.38 µg/100g FW) levels. Carotena showed the highest total carotenoid content (60.52±1.76 µg/100g FW) and β-carotene (26.99±0.44 µg/100g FW), while Snow White had the lowest values across most parameters. Valentena also led in anthocyanins (101.56±3.9 mg/L FW) and total flavonoids (79.56±10.36 mg/100g FW), with Carotena having the highest vitamin C content (60.05±2.93 µg/g FW). DPPH assays indicated that Valentena showed the most effective antioxidant (IC50 = 43.65±3.56 mg/mL FW), followed by Carotena and Snow White. Hierarchical clustering and pricipal component analysis (PCA) revealed distinct biochemical profiles: Valentena and Carotena shared similarities in carotenoids and antioxidant activity, whereas Snow White differed significantly. Linear discriminant analysis identified lycopene, chlorophyll b, and β-carotene as major differentiators, highlighting the diverse nutritional and antioxidant properties of these cauliflower varieties. The findings highlight the potential of Carotena and Valentena for health-conscious consumers seeking nutrient-rich, antioxidant benefits in functional meals.

A deep-sea spa: the key to the pearl octopus’ success
Authors: Barry Jim
Published: January 2025

Pearl octopuses brood their eggs in abyssal warm springs more than 3 km below the sea surface. This warmth speeds up the development and hatching of their eggs, shortening the brooding period for octopus mothers tending their nests. Exploiting this rare deep-sea heat source provides a reproductive boost that ensures the survival of this abyssal octopus.
Measuring one’s ability to alter, change, and reduce lumbar flexion on call and underload part II
Authors: Williams Brogan , Horsching Aaron
Published: January 2025

While deadlifting, flexing the spine is inevitable; however, can it be minimized? The research question is, “Can a skilled, experienced weightlifter reduce their lumbar flexion under load by incorporating a structured warm-up?” An expert-level weightlifter performing flexion under 60 kg of load (on an Olympic Elieko Barbell) was observed, and his lumbar spine was measured on two separate occasions. Day 1 had no warm-up, and day 14 included a specific, structured warm-up. A digital inclinometer was positioned over the S1/S2 and L5/T12 for all measurements. The participant flexed 26° (61.9% of total flexion range of motion [TFROM]) on day 1 and 11° (18.6% of TFROM) on day 14. Implementing the warm-up not only increased both extension and flexion range of motion but also seemed to enhance the lifter’s ability to alter, change, and reduce lumbar flexion on call, under load, and on demand.
Combined intrafocal K-wire pinning for unstable pediatric distal forearm fractures
Authors: Jerome J. Terrence Jose
Published: January 2025

This technical note presents a combined antegrade and retrograde intrafocal K-wire pinning technique for managing unstable and displaced distal third of the diaphysis fractures in older children (>10 years). While intrafocal pinning is established for distal radius fractures, its use in complex, unstable fractures in this age group is less explored. These fractures are prone to re-displacement, and single-direction pinning may be insufficient due to displacement severity, reduction challenges, or soft-tissue injury. The combined approach offers enhanced stability, particularly in older children at higher risk of re-displacement. The author reports good functional and radiological outcomes with no complications in their case series and details the surgical steps involved in this combined technique.

Published: January 2025

This research article provides an examination of the challenges faced by students during the composition of procedure texts. It aims to uncover factors influencing students' proficiency. Utilizing thematic analysis, we analyzed students' written texts and conducted interviews with junior high school English teachers and students, providing a holistic perspective.  Four significant areas of difficulty were identified: minimal word and phrase variations, lack of clarity and precision, ignorance of writing mechanisms, and challenges with grammar and spelling. These challenges provided insights into the recurring patterns of students’ writing. Factors contributing to these difficulties included motivational factors, language environment, language proficiency, and formal presentation aspects. Student motivation to write and seek comments was hindered by low intrinsic motivation. Students' writing talents were also shaped by language exposure and proficiency, which varied by background and experience. Additionally, formal presentation characteristics and technology-based teaching strategy restrictions underlined the need for improved infrastructure to accommodate various and engaging teaching methods. In conclusion, the research sheds light on the intricate landscape of students' struggles in composing texts and underscores the urgency of providing tailored teaching strategies to address these challenges effectively while also keeping the influencing factors in consideration.

Authors: Rahim Essy Puspita , Maimunah Maimunah , Suanto Elfis
Published: January 2025

This research is motivated by the fact that numeracy skills are fundamental abilities that every student must possess. However, observations in the field indicate that students' mathematical abilities, particularly in the topic of systems of linear equations with two variables (SPLDV), are still relatively low. This study aims to describe students' numeracy skills, which are divided into three stages: (1) knowing, (2) applying, and (3) reasoning. The study involves 20 eighth-grade students as subjects. The method used is descriptive qualitative, with data collection techniques including tests, interviews, and documentation. Data analysis is conducted based on three levels of numeracy skills: high, medium, and low. The results show that students' computational abilities in the SPLDV material are generally low, with an average score of 33%. The implications of these findings highlight the need for the implementation of more varied and contextual teaching strategies to enhance students' computational skills. This research can serve as a foundation for teachers to provide further assistance to students facing difficulties, with an emphasis on improving overall computational abilities.
Directed Evolution and Unusual Protonation Mechanism of Pyridoxal Radical C–C Coupling Enzymes for the Enantiodivergent Photobiocatalytic Synthesis of Non-Canonical Amino Acids
Authors: Cheng Lei , Bo Zhiyu , Krohn-Hansen Benjamin , Yang Yang
Published: January 2025

Visible light-driven pyridoxal radical biocatalysis has emerged as a new strategy for the stereoselective synthesis of valuable noncanonical amino acids in a protecting-group-free fashion. In our previously developed dehydroxylative C−C coupling using engineered PLPdependent tryptophan synthases, an enzyme-controlled unusual a-stereochemistry reversal and pH-controlled enantiopreference were observed. Herein, through high-throughput photobiocatalysis, we evolved a set of stereochemically complementary PLP radical enzymes, allowing the synthesis of both L- and D-amino acids with enhanced enantiocontrol across a broad pH window. These newly engineered L- and D-amino acid synthases permitted the use of a broad range of organoboron substrates, including boronates, trifluoroborates and boronic acids, with excellent efficiency. Mechanistic studies unveiled unexpected PLP racemase activity with our earlier PLP enzyme variants. This promiscuous racemase activity was abolished in our evolved amino acid synthases, shedding light on the origin of enhanced enantiocontrol. Further mechanistic investigations suggest a switch of proton donor to account for the stereoinvertive formation of D-amino acids, highlighting an unusual stereoinversion mechanism which is rare in conventional two-electron PLP enzymology.
Diastereo- and Enantioselective Chemoenzymatic Synthesis of Chiral Tricyclic Intermediate of Anti-HIV Drug Lenacapavir
Authors: Fu Wenzhen , Liu An , Yang Yang
Published: January 2025

Despite its great potential, the development and implementation of scalable new-to-nature biocatalytic transformations in the chemoenzymatic synthesis of clinically significant pharmaceuticals still present a considerable challenge. We developed a chemoenzymatic synthesis of very recently developed anti-HIV drug lenacapavir’s 5/5/3 fused tricyclic fragment featuring an unusual chiral cyclopropane moiety. Key to this development is a biocatalyst-controlled, fully diastereo- and enantiodivergent cyclopropanation of a highly functionalized vinylpyrazole substrate, granting access to all four possible stereoisomers of lenacapavir cyclopropane. High-throughput experimentation led to the discovery of heme-dependent globins, including nitrous oxide dioxygenase (NOD) and protoglobin (Pgb), as promising cyclopropanation biocatalysts. Directed evolution furnished a highly diastereo- and enantioselective cyclopropanation (up to 99:1 d.r. and 99:1 e.r.). Further developed downstream chemical cyclization afforded the desired lenacapavir 5/5/3 fused tricycle with great stereochemical purity.

Authors: Krishna K.V. Swathi , Sneha K.
Published: January 2025

The goal of the current study is to formulate and evaluate Rizatriptan benzoate pellets using sodium alginate, Methylcellulose, and carbopol in varying ratios as release-retarding polymers using the solution/suspension layer technique. This will prolong the drug's release, reduce the peak and valley effect in the plasma, and offer patients convenience. For a maximum of six months, the formulation undergoing stability studies has been examined for drug content and in vitro dissolution. The estimated shelf life of the reagent was ascertained by comparing the computed and actual assays. None of the tested parameters of the formulations showed any apparent changes, indicating that the formulations were stable. Stability tests were carried out for six months at 250C/60% and 400C/75% RH for the optimal formulation of F12 every two months. By comparing the calculated and observed assays, the assay's expected shelf life was 14 months. According to the results, formulation F12 was stable because there were no appreciable changes in the drug content analysis or in-vitro dissolution research.

Published: January 2025

Background and Aim of Study: The realm of education is in a constant state of evolution, necessitating that teachers at K-12 and tertiary levels continually update their practices through continuous professional development (CPD). The COVID-19 pandemic has significantly accelerated the adoption of online CPD, encompassing self-driven initiatives, government-led programs, and third-party offerings, notably those by the British Council in the MENA region, which is the emphasis of this study. This transition to online platforms initially involved leveraging Zoom, and subsequently, WhatsApp.
The aim of the study: to map the process of CPD-infused online training by analyzing meeting schedules, topics discussed, group dynamics, and interaction patterns. Additionally, it seeks to develop a CPD-based system that can be replicated or scaled for broader implementation.
Material and Methods: This descriptive multi-case study is conducted on two WhatsApp groups dedicated to enhancing the skills and competencies of 990 and 780 MENA teachers, respectively. For data collection, the study employed two primary tools: participant observation, and analysis of archived data from CPD-based multimedia-focused discussions in both e-groups over a fixed period of 40 days.
Results: The research provides a comprehensive overview of the CPD process and a cost-effective scalable CPD-centric system based on six key elements: e-platforms, e-meetings, archiving, certification, website and organization that orchestrates and streamlines the entire process. This CPD-driven system offers guidelines for institutions and policymakers looking to replicate this system in their educational contexts, with the goal of upgrading teachers’ pedagogical expertise.
Conclusions: This study contributes to understanding the effectiveness and scalability of online CPD initiatives using platforms like WhatsApp, particularly in regions like MENA, and offers insights for stakeholders aiming to implement similar strategies for enhancing teacher professional development.

The aim of our research was to investigate the impact of the use of mobile devices in mobile technology (MT)-enabled experiential learning (EL). Methods/Analysis: The basis of the research was an experiment. Quantitative data included pretest and post-test results of two groups of students (ELs and regular education students). Qualitative data consisted of individual analysis of a final questionnaire composed of 37 items, some of which were open-ended. A 5-point Likert scale was used for evaluation, and some questions were open-ended. Findings: The results showed that the average knowledge gained in the EL group's post-test increased compared to the regular class. We found that after the photographing/note-taking phase, students with the ability to use mobile devices generally lost interest in further observation. We also found that both groups had great difficulty in the question design and comparison sections, in finding answers to the prepared questions. Novelty/Improvement:it became apparent that the teaching process needed to be modified. The photo-taking phase should be done after close observation so that the sensory experience is not replaced by mobile devices. The comparison phase did not show a significant result in any of the observed viewpoints and can be omitted. The sensory experience, sound recording, requires some modifications, more effectively applied in the classroom environment, as ambient noise was a problem in the teaching process. Doi: 10.28991/ESJ-2024-SIED1-017 Full Text: PDF

Published: January 2025

This study presents the design and development of new features in the New-Siransija application using an object-oriented system approach. The main objective is to optimize employee performance measurement and improve personnel administration within the Gorontalo Provincial Government. This study uses a qualitative methodology, adapting the first three stages of the Software Development Life Cycle (SDLC). The weakness identified in the current system lies in the assignment feature input section. To overcome this, this study proposes the integration of the upload feature for assignment documentation, which is linked to the payroll recording system. These enhancements aim to prevent potential abuse and increase accountability by requiring employees to provide proof of completed assignments. The development process involves a qualitative analysis of user needs and system requirements, followed by the design and implementation of new features. The results of the study show that the features designed in the New-Siransija application which were developed through an object-oriented system approach improve employee performance measurement and encourage accountability within the Gorontalo Provincial Government.

Basic education has an important role in forming the foundation of a child's character. The city of Surakarta is a city that has many choices of elementary schools, both public and private. The large number of elementary schools requires clustering, so that it can help the government and the community in decision making. The most important factors in choosing an elementary school are school facilities and costs, so the clustering in this research is based on educational costs and the facilities provided by the school. The method used in this research is the K-Medoids clustering method, namely a clustering method that groups data based on groups that have maximum similarity. To evaluate the clustering results, silhoette value calculations are used. It is hoped that this research can help the government, especially the education department, in mapping elementary schools in the Surakarta area and assist parents in determining elementary school choices.

The issues investigated in this research include the accuracy of artificial intelligence (AI) scoring of essay answers, the challenges of validity and fairness in automated scoring, as well as potential biases in the algorithms used, and how these affect academic assessment results compared to human scoring. The method used in this study consists of several systematic steps. First, data was collected by asking relevant questions to an artificial intelligence (AI) platform. After that, the questions are inputted into AI platforms such as Copilot, Gemini, and Blackbox AI. Next, the resulting answers are analyzed using machine learning algorithms and natural language processing (NLP) to ensure the quality and depth of analysis. The answer results are then tested to evaluate their accuracy and relevance to the context of the question asked. the analysis results are visualized in the form of graphs or tables. this research shows that artificial intelligence (AI) has great potential in the automated assessment of essay answers. The results showed that Copilot got the highest score of 63.4%, Gemini 50.5% and Blackbox.AI 56.9%. However, the answer accuracy results between each AI Platform are still below 70%, meaning that the answers from the AI platform are still far from expectations. The next research recommendation is to retest the AI Platform using other methods to get accurate and consistent results.
