Graduate Student’s Perception on Effectiveness of Virtual Education during Covid-19: Evidence from Structural Equation Modelling in Nepal
Authors: Adhikari Bikash , Lawaju Purnima , Adhikari Kabita , Bohaju Sabina
Published: September 2024

Background: The COVID-19 pandemic forced educational institutions worldwide to shift to online learning, disrupting traditional academic calendars. In Nepal, this transition significantly impacted graduate students, raising concerns about the effectiveness of virtual education.
Objective: This study aims to examine the effectiveness of virtual education on student satisfaction and performance during the COVID-19 pandemic among graduate students in the Kathmandu Valley.
Method: Based on the achievement goal theory, 203 graduate students from management colleges in Kathmandu Valley were selected through purposive sampling. Data were collected using a structured questionnaire administered via KOBO Toolbox. Both descriptive and inferential analyses, including Structural Equation Modeling (SEM), were employed to analyze the data.
Result: The findings reveal that while the majority of students showed a positive attitude toward online classes, dissatisfaction arose due to a lack of training and familiarity with new information technologies. The SEM results indicate that course design, prompt feedback, and student expectations significantly influence student satisfaction, which in turn mediates the relationship between these factors and student performance. Challenges such as power outages, difficulty concentrating, lack of access to technology and insufficient instructor knowledge were identified as major obstacles.
Conclusion: Although graduate students in Kathmandu Valley reported a generally positive outlook towards virtual education, several significant challenges need to be addressed to improve the effectiveness of online learning, particularly in terms of instructor quality and technological infrastructure.

Authors: Jaisi Tilak , Basyal Devid Kumar , Prajuli Seeprata
Published: September 2024

Background: Interest rate fluctuations have long been a critical research topic, particularly in relation to retail loan holders. In Nepal, the status of retail loans has been progressively improving, making it essential to understand how interest rate changes affect retail loan borrowers in Kathmandu Valley.
Objective: This study aims to investigate the impact of interest rate fluctuations on retail loan holders in Kathmandu Valley. It seeks to determine how these fluctuations influence banking performance and retail loan products in the context of Nepalese financial institutions.
Method: A descriptive research design was employed, focusing on retail loan holders from Nepalese financial institutions in Kathmandu Valley. A sample of 383 retail loan borrowers was selected using simple random sampling. Data were collected via a structured questionnaire. The analysis involved descriptive statistics, correlation, regression, as well as pre-estimation and post-estimation techniques.
Result: The findings indicate that interest rate fluctuations have a positive and significant impact on retail loan products offered by Nepalese banking institutions. Higher interest rates tend to enhance retail loan offerings, contributing to improved banking performance and increased creativity in loan practices.
Conclusion: The study underscores the positive role of interest rate fluctuations in shaping retail loan products and banking performance in Nepal. It suggests that financial institutions could benefit from adjusting their interest rates to foster better loan practices and improve overall performance. For economic benefit, banks should consider lowering interest rates and providing attractive returns to depositors to balance their profitability and enhance financial stability. This research provides a foundation for further academic exploration into the effects of interest rates on retail loan behavior.

Empirical Analysis of Paddy Value Chains in Nepal: Evidence from Logistic Regression Modeling
Authors: Sah Deepa Kumari , Devkota Niranjan
Published: September 2024

Background: In the South Asian region, rice is one of the most significant staple food crops. The value chain provides a lot of support for a seamless operation from growth to reaching clients' hands. It not only aids farmers, but it also creates opportunities at every stage. As a result, the goal of this research is to determine the value chain analysis of paddy products in Nepal.
Objective: The objectives of the study were to analyse value chain analysis of paddy product, and to identify the constraints and opportunities of rice value chain in Parsa, Siraha and Saptari districts of Nepal.
Method: The thesis followed the design of explanatory research and collected data using structured questionnaires. Binary logistic Model was used for inferential analysis. Siraha, Saptari and Birgunj (Parsa) districts are chosen purposely. 260 respondents were conveniently sampled from farmers and traders.
Result: The study shows the cooperatives play role in accessing credit, accessing inputs, and training with the help of government and non-government organization. The study tells us the fact that paddy value chain functions in a traditional way, there is no innovative way of integrating the chain actors. The cooperatives are involved in both input supply and credit service. Ages, off-farm income, access to information, access to input are the factors that add value in paddy value chain.
Conclusion: This research is based on value chain analysis of paddy product in Parsa, Siraha and Saptari districts. Generally, the price of rice/paddy goes down in the post-harvest period due to heavy arrivals in the market and later shoots up, which results in unstable price. Providing better access to credit to farmers to reduce dependence on money lenders can solve the existing problem.

Qualitative Remote Data Collection Guidance 2024
Authors: Boardman Felicity , Roberts Julie , Clark Corinna , Onuegbu Chinwe , Harris Bronwyn , Seers Kate , Staniszewska Sophie , Aktas Puren , Griffiths Frances
Published: September 2024

In 2020, the sudden onset of the COVID-19 pandemic forced qualitative health and social care researchers to rapidly convert to remote methods of data collection (i.e. methods of collecting research data when the researcher and participant are not together in the same space). In a post-COVID-19 research landscape, use of remote qualitative methods is now a choice not a necessity. This guidance was developed to support researchers who are making decisions between the use of remote or face-to-face methods. Methods The guidance was developed by a team of experienced health and social care researchers through two literature reviews (a scoping review and a realist review), interviews with 25 researchers and research participants and a consensus conference (attended by 27 research stakeholders) where the guidance was ratified. A diverse public reference group (PRG) with eight members informed all stages of the research process and guidance production. Conclusions The literature broadly demonstrates the equivalence of remotely collected qualitative data vis-à-vis face-toface, both in terms of data quality and data depth (Boardman et al, 2022). Additionally, the use of remote methods can make qualitative research less resource intensive, with reduced environmental harms (travel). It can also be more convenient for participants and researchers alike and can facilitate access to more diverse groups of geographically dispersed participants, increasing diversity and inclusivity in health and social care research. Care must be taken, however, to ensure that remote methods are not exclusionary and to explore, before data collection commences, which voices are silenced by their use. Identifying participants’ needs, typical communication channels, abilities and technology access in ways that take account of their socioeconomic and cultural backgrounds and local contexts are pivotal to this endeavour. Researchers should support participants to harness the autonomy that remote methods can bring, so that they may directly shape the research encounter/s to suit their circumstances and needs. However, it is important to note that this might include the decision to defer entirely to face-to-face methods, or to offer face-to-face as an adjunct method within a hybrid remote/face-to-face design.

Парентеза як засіб експресивного синтаксису в історичному романі Павла Загребельного "Диво"
Authors: Turchak Olena
Published: September 2024

The article analyzes the parenthetical (inserted) constructions in the historical novel "The Miracle" by Pavlo Zahrebelny. It has been established that parenthetical elements have a different syntactic structure. They are represented by words, phrases and various types of sentences, including textual formations. There is a small number of one- and two-component parentheticals. Most of them are multicomponent insertions. The grammatical compatibility of the parenthetical constructions with the main clause is taken under consideration. It has been established that parentheticals are joined to the main clause by both conjunctive and non-conjunctive relations. Attention is paid to the punctuation marks of the inserted components and their place in the sentence. The functional diversity of parentheses is determined. It has been found that they are used to clarify, explain, express desire, satisfaction, dissatisfaction, assumption, objection, doubt, etc. Particular attention is paid to parenthetical constructions as a means of expressive syntax and a marker of sentence modality. The expressiveness of parenthetical constructions is manifested through their versatility, redundancy, spontaneity and violation of the linear plan of presentation.
Використання досвіду Інституту польської глотодидактики Ягеллонського університету у Львівському національному університеті імені Івана Франка
Authors: Zbyr Iryna
Published: September 2024

The article concentrates on the current state and prospects of the development of linguodidactics of Ukrainian as a foreign language at the Ivan Franko National University of Lviv in the post-war period. One of the new solutions in this direction is the opening of an institution like the Institute of Polish Glottodidactics of the Jagiellonian University as a separate division of the Faculty of Philology, which, on the one hand, is engaged in training and certification of foreign students’ knowledge of Ukrainian as a foreign language, and, on the other hand, has become a research center that trains specialists in teaching Ukrainian as a foreign language, develops methods of teaching Ukrainian as a foreign language (as a second or inherited language), conducts scientific research, as well as organizes conferences, symposia and trainings for Ukrainianists from various centers around the world. In the future, this will not only help to reorganize the work of preparatory faculties (departments), departments of Ukrainian Studies, centers of international education of Ukrainian universities, but also to popularize the Ukrainian language, history and culture around the world. Today, this issue is often raised at many conferences and meetings, but there is no unequivocal answer either from the state or individual institutions. Therefore, the Institute of Polish Glottodidactics, which has gone through a long and difficult path of formation, can become a good example in the implementation of this idea.
Electrocardiographic Criteria for Diagnosis of Acute Myocardial Infarction in Patients with Left Bundle Branch Block
Authors:   ClinicSearch Publishing LLC, Habib Mohammed
Published: September 2024

In patients with normal heart and normal conduction system, the initial depolarized segment in ventricle is interventricular septum which begins with septal fascicle of the left bundle branch from left side and direction to right side followed by a simultaneous depolarization of the remaining ventricular free walls from endocardium to pericardium via the right and left bundle branches. But among patients with left bundle branch block (LBBB), the initial septal activation is changing direction and become from right to left then the left ventricular activation is delayed, ST segment and T wave abnormalities occur, and septal Q waves indicative of an MI are absent in this condition. About 0.5 percent of patients with acute myocardial infarction had left bundle-branch block. Because this changes the patients with left bundle branch block (LBBB) and acute myocardial infarction (MI) is challenge to the clinician. The diagnosis of MI with electrocardiogram (ECG) is so difficult in the setting of LBBB because of the characteristic ECG changes caused by altered interventricular septal and left ventricle free wall depolarization. Here we review the ECG diagnostic criteria included all criteria until now and short summary of patient with acute MI and LBBB condition.

Authors: Seno Reya , Engracia Marie Kei , Hairulla Nurbaiyina , Malubay Kryshann Mar , Santillana Lynuel , Orias Jessica
Published: September 2024

Background: The rate of unwanted pregnancies among university students is increasing each year, despite extensive public awareness of and access to contraceptives. The study is centered on women since, historically, when it comes to contraception, women have borne a disproportionate share of the burden, and if birth control fails to work, their bodies will be the ones to bear the consequences. Objective: The objective of this study is to assess the knowledge and attitude of female undergraduate students of a higher institution in Northern Mindanao, Philippines, towards contraceptive use. The results of the study may be utilized as a guide to formulate effective health education strategies for university health nurses for this vulnerable population. Methods: A quantitative correlational design was used in this study, which utilized Google Forms to collect data from four hundred fourteen (414) respondents selected through purposive sampling at a higher education institution. The researchers utilized a researcher-made questionnaire to assess general awareness, knowledge, and attitude toward contraceptive use. Results: The study revealed that most of the respondents are generally aware of the proper usage of contraceptives, highly knowledgeable, and have a positive attitude towards contraceptive use. Most of the respondents obtained this knowledge from media sources. Apart from the relationship status, other demographic factors have no significant correlation with the knowledge and attitude towards contraception of the respondents. Notably, results show that there is a significant relationship between knowledge and attitude towards contraceptive use among undergraduate female students. Conclusion: The research indicates that a knowledge-rich community can have an impact on attitudes toward contraceptive use. The researchers recommend extensive and comprehensive sexual education programs in academic institutions to address this reproductive health concern among university students.

Authors: Ismail Muhammad , - Azra , Khan Dilawar
Published: September 2024

Climate change has raised ample concerns about achieving zero hunger. The goal of the study is to investigate the link between climate change and eradicating hunger in Asian nations. The data span is from 2001 to 2020 from World Bank and KOF. The effect was investigated using the Pool Mean Grouped/Panel Autoregressive Distributed Lag Model which shows that climate change, both in the short-run and long-run, hinders progress toward achieving zero hunger. The conclusion shows that in the long run, a rise in per capita income, globalization, and labor force participation boosts the progress towards achieving zero hunger but, in the short run, per capita income has a significant effect, and globalization and labor force participation have an insignificant effect on zero hunger. Finally, this study offers some recommendations to achieve zero hunger.

„Spotkały się, aby utworzyć jedną osobę i jedną hipostazę”: krytyka polskiego przekładu fragmentu wyznania chalcedońskiego w "Dokumentach Soborów Powszechnych" oraz propozycja alternatywnego tłumaczenia
Authors: Calore Giacomo
Published: September 2024

W niniejszym artykule autor podejmuje problem tłumaczenia fragmentu z chalcedońskiego wyznania wiary na język polski, który znajduje się w Dokumentach Soborów Powszechnych. Autor przedstawia tezę, że nie odpowiada ono teologicznej myśli Ojców soborowych stojącej za tą częścią definicji. Celem artykułu jest uzasadnienie tej tezy oraz propozycja alternatywnego przekładu. Stosowana metoda jest złożona: po pierwsze, rekonstrukcja genezy fragmentu poprzez badanie kontekstu historycznego i filozoficzno-teologicznego jego powstania oraz analizę literacką; następnie, na podstawie wyników tych badań, analiza chrystologii Ojców zawartej w tym passusie, która pozwoli poddać w wątpliwość wyjściowe tłumaczenie. Artykuł został zatem podzielony w następujący sposób: analiza gramatyczna fragmentu; kontekst dalszy i bliższy powstania tekstu wyznania; analiza literacka; analiza teologiczna i przedstawienie nowego tłumaczenia. Oprócz tekstu wyznania, główne źródła, będące przedmiotem badań, to Epistula Altera ad Nestorium Cyryla Aleksandryjskiego i Tomus ad Flavianum papieża Leona. Wnioski badań, dobrze uwydatniają różnicę między heretykami a Ojcami Kościoła w posługiwaniu się starożytną filozofią dla wyrażenia wiary. Wykazują ponadto metafizyczne novumna temat pojęć osoby i natury wynikające z treści wyznania i ówczesnej patrystycznej refleksji, które stanowi zagadnienie nadal aktualne, a które przedyskutowane tłumaczenie niestety niejako przyćmiewa.
Bizantyńska obecność na Krymie i pamięć o niej w literaturze Słowian Południowych i Wschodnich z X–XVI w. (casus biskupów-męczenników z Chersonezu Taurydzkiego)
Authors: Leszka Mirosław J. , Brzozowska Zofia
Published: September 2024

Celem artykułu jest przedstawienie początków i rozwoju kultu w Kościele wschodnim – zarówno w jego bizantyńskim, jak i słowiańskim wymiarze – siedmiu świętych męczenników: Bazylego, Efrema, Eugeniusza, Elpidiusza, Agatodora, Eteriusza i Kapitona, którzy przynajmniej od IX–X w. czczeni byli jako biskupi Chersonezu, którzy przyczynili się do upowszechnienia chrześcijaństwa na obszarze Półwyspu Krymskiego. W pierwszej części artykułu staramy się zrekonstruować początki tego kultu w Bizancjum i pokazać, w jakim stopniu wczesna tradycja hagiograficzna biskupów-męczenników z Chersonezu została ukształtowana przez zmieniającą się sytuację polityczną w cesarstwie bizantyńskim. Część druga poświęcona jest słowiańskiemu wymiarowi ich kultu: omawiamy tu najwcześniejsze wzmianki o tych świętych, jakie można znaleźć w źródłach cerkiewnosłowiańskich, analizując wszystkie poświęcone im teksty hagiograficzne, jakie zachowały się na wschodzie Słowiańszczyzny oraz na południowosłowiański (bułgarski i serbski) materiał rękopiśmienny z X–XVI w. Uwagę poświęcono także wizerunkom siedmiu biskupów-męczenników z Chersonezu w średniowiecznej sztuce prawosławnej.
Teologia nicejska. Historyczna i systematyczna propozycja interpretacyjna Lewis’a Ayres’a
Authors: Woźniak Robert Józef
Published: September 2024

Tematem artykułu jest interpretacja teologii nicejskiej zaproponowana przez Lewisa Ayresa w jego monografii Nicaea and its Legacy. Główną część stanowi tu analityczna prezentacja dwóch istotnych momentów propozycji Ayresa. Po pierwsze chodzi o wyodrębnienie cech wspólnych wielości interpretacji powstałych po wydarzeniu nicejskim, które jest konieczne do utrzymywania istnienia historycznego fenomenu teologii, którą można by określić ogólnie jako nicejską. Po drugie, zgodnie z wyjściową intencją autora wyodrębniony wcześniej zbiór cech istotnych i charakterystycznych dla teologii nicejskiej zostanie przestawiony jako uniwersalny paradygmat dla teologii trynitarnej i teologii systematycznej w ogóle. W zakończeniu artykułu dokonana zostanie wstępna ocena zdobyczy wkładu ujęcia Ayresa, szczególnie z perspektywy pracy teologa systematyka. W ten sposób zostanie wyartykułowane istotne dla naszego autora przekonanie o jedności systematyki teologicznej, dogmatyki i teologii historycznej. Ayres nie proponuje zatem jakiegoś sztywnego inmartwego powrotu do Nicei, ale ukazuje ją jako wydarzenie określające istotny cechy warsztatu teologa.
Il mistero dell’Incarnazione nelle "Enarrationes in Psalmos" di Sant’Agostino
Authors: Turzyński Piotr
Published: September 2024

L’articolo presenta l’importanza del tema dell’Incarnazione nel commento di S. Agostino ai Salmi. Secondo il Vescovo di Ippona, il Mistero dell’Incarnazione è uno dei momenti chiave della storia della salvezza. Agostino, negli scritti dei filosofi antichi, non ha trovato un modo in cui l’uomo potesse raggiungere il mondo divino a cui aspira. Tuttavia, il cristianesimo gli ha indicato la via dell’umiltà (via humilitatis) nell’Incarnazione. In Cristo, Dio assume la condizione umana e, senza perdere nulla della sua divinità, introduce l’uomo nel mondo divino dell’eternità. Agostino è convinto che l’umiltà del Figlio di Dio nel mistero dell’Incarnazione fa dell’umiltà di Dio il nucleo della fede cristiana. E la stessa categoria dell’umiltà non ha solo una dimensione morale ma anche filosofica. In virtù dell’Incarnazione, Cristo diventa rappresentante degli uomini e il sacerdote che offre se stesso come l’offerta a Dio Padre. E tutta la Sua opera salvifica costituisce l’unità e ha il suo fondamento, senso, peso e significato proprio nel mistero dell’Incarnazione.
            Agostino spiega l’Incarnazione in modo biblico e figurato. Per lui Cristo in quanto Dio è la Patria da cui l’uomo è venuto e verso la quale è diretto, ed in quanto uomo è la Via lungo la quale andiamo per raggiungere la meta. In virtù dell’Incarnazione, il tempo umano acquista un carattere propositivo e tende al suo compimento nell’eternità.

Published: September 2024

Исследованы поляризационные свойства двухканального пространственного акустооптического фильтра, основанного на дифракции в два симметричных брэгговских порядка. Продемонстрирован вариант, когда в процессе фурье-обработки изображения контуры в разных каналах образуются в разных поляризациях, причем формирование контуров происходит на разных акустических частотах. Вариант подтвержден экспериментально на примере оптической фурье-обработки изображения, переносимого излучением с длиной волны света 0.63 мкм. В качестве фильтра пространственных частот использована акустооптическая ячейка из парателлурита, позволившая выделить контур изображения по одному каналу на частоте звука 34 МГц, а по другому – на частоте 42 МГц.

Authors: Martynov K. V. , Kulemin V. V. , Krasavina E. P. , Rumer I. A. , Nevolin Yu. M. , Kulyukhin S. A.
Published: September 2024

This work examines stone-cast matrices (SCM) obtained by fusing basalt and Sr, Ln (Ce, Nd, Gd) oxides. It has been established that, as a result of the fusion of basalt with SrO, matrices are obtained containing glass and clinopyroxene as the main phases. Strontium partially replaces calcium in clinopyroxene, but mostly enriches the melt in contact with crystallizing clinopyroxene. When this melt cools, glass is formed containing up to 31 wt% SrO. As a result of the alloying of basalt with oxides of rare earth elements (REE) MxOy: CeO2, Nd2O3, Gd2O3, taken in a mass ratio of 4 : 1 and 2 : 1, SCM are formed, the main permanent phases of which are glass and clinopyroxene. In addition, magnesioferrite can crystallize from a basaltic melt upon cooling, and, depending on the mass ratio of basalt to MxOy, phases of cerianite CeO2 or britholite Ca(Nd,Gd)4(SiO4)3O can crystallize.

Published: September 2024

Protecting soil from pollution by oil and petroleum products is an important environmental task. Sources of oil contamination of soil are not only oil fields, but also industrial facilities that directly or indirectly use petroleum products. Of interest are studies aimed at studying the processes of changes in oil during its degradation in the soil. When oil degrades, polycondensation processes occur on the soil surface, which leads to structural changes in the oil. We compared the composition and properties of oil after production and long-term presence on the soil surface. An analysis of oil-contaminated soils was carried out at a distance of 0–5 and 0–10 m from the source of pollution and from a depth of 0–15 cm. Oils degraded in the soil are also susceptible to the effects of natural radionuclide background. In this regard, the work investigated the impact of gamma radiation on oil degraded in the soil of the Surakhani oil field of Azerbaijan. Oil samples were taken from a well and from oil-contaminated soil and separated into three components: oils, resins, and asphaltenes. The results of mass spectrometric and IR spectrometric studies of the indicated fractions of crude and degraded oil samples are presented, and the patterns of formation of gaseous products during their radiolysis are established.

Authors: Shevchenko V. P. , Shevchenko K. V. , Andreeva L. A. , Nagaev I. Yu. , Myasoedov N. F.
Published: September 2024

The efficiency of incorporating deuterium into 4-aminobutanoic acid (GABA) has been studied. When using D2O at 200°C, about 0.5 deuterium atom was included in GABA on average. When using D2O with trifluoroacetic acid (1 : 1) at 250°C, an average of 1.49 deuterium atoms with a yield of 15% were included. When using the solid-phase method, it was possible to introduce about 3 deuterium atoms per GABA molecule. During isotopic exchange with D2O, the use of a palladium–rhodium mixture pretreated with gaseous deuterium made it possible to obtain [D]GABA with the deuterium content of 4.5–4.6 atoms. But in both cases, the yields of [D]GABA were low. Preparative amounts of [D]GABA were obtained using additional carriers. The best result was obtained when applying GABA to zeolite. Using D2O and 5% Pd/BaSO4–GABA–zeolite pretreated with deuterium gas, [D]GABA was obtained with an average content of 1.5–2.0 deuterium atoms and a yield of about 30%.
Related work analysis for determination of fatigue state based on eye movements monitoring
Authors: Shoshina I. I. , Kovalenko S. D. , Kuznetsov V. V. , Brak I. V. , Kashevnik A. M.
Published: September 2024

We have reviewed theoretical background of detecting functional state of fatigue based on the strategy of eye movements. Also, modern methods for assessing eye movements were considered. Based on our literature review, we can conclude that nowadays there are multitude numerical characteristics of eye movements, the dynamics of which can hypothetically make it possible to assess degree of fatigue. However, there are still no proposals for a method for determining the degree of fatigue based on an analysis of the strategy of eye movements. In this regard, according to the concepts of static and dynamic vision, it is proposed to consider the shift in the numerical characteristics of eye movements towards characteristics that reflect the strategy of dynamic vision as evidence of fatigue.
Fatty acids significance in improvement athlete’s aerobic performance: review and prospects
Authors: Lyudinina А. Yu. , Bushmanova E. A. , Bojko Е. R.
Published: September 2024

Fats are the second most important energy substrates after carbohydrates. They are actively used as energy substrate in skeletal and cardiac muscles during aerobic exercise. This review presents modern data about the effects of different exercise intensities on lipid metabolism, the profile of plasma fatty acids (FAs), and the rate of fat oxidation. FAs metabolism is chiefly determined by exercise intensities and diets of athletes. Mobilization and oxidation of FAs extension with the increase of duration and intensity exercise, and under cold conditions when fats are used for energy supply and thermoregulation. The essential and saturated FAs are the most labile to exercise. An interesting direction for future research would be a study of maximal fat oxidation as a new marker of aerobic performance (AP), since there are practically no literature resources on the contribution of different classes of FAs to the AРin elite athletes. In addition, there is no clear understanding of how FAs oxidation is regulated and limited in skeletal muscles during a high-intensity exercise, of the mechanisms of transport and utilization of different classes of FAs depending on diet and training status. Such understanding would allow us to conduct more thorough monitoring of the functional status of athletes, and design the training process suitable to aerobic loads.

Subjetividad, alteridad y ethos intercultural en la educación colombiana
Authors: Benavides-Franco Alexander
Published: September 2024

La hipótesis de este trabajo es que los procesos de generación de subjetividades e identidad nacional llevados a cabo por el Estado, a través de la escuela y sus políticas educativas, no han abandonado el modelo eurocéntrico del sujeto colonizador. Como resultado, han contribuido a la continuidad y naturalización de la racionalidad que alimenta el conflicto, en lugar de resistirla y superarla. En este sentido, se propone abordar esta problemática desde una perspectiva intercultural, en diálogo con la perspectiva levinasiana de la alteridad. Así, se examinan algunas herramientas que el pensamiento intercultural crítico puede ofrecer a las políticas educativas colombianas, con el fin de promover procesos de subjetivación en la escuela que permitan la configuración de un ‘ethos intercultural’.
Estrategias de aprendizaje activo en la enseñanza de la química: aula invertida-técnicas de aprendizaje virtual
Authors: Gómez-Delgado Diana Carolina , Arteaga Fuertes Danny Alejandro
Published: September 2024

En la actualidad, la academia puede centrarse en la búsqueda de nuevas metodologías de enseñanza para recrear ambientes únicos, con ventajas como la versatilidad y adaptabilidad de los recursos y del tiempo, generando nuevas posibilidades de interacción, desarrollo y aprendizaje. Además, se busca trasladar el eje central del acto pedagógico desde el profesor hacia el estudiante, transformándolo en el responsable y protagonista de su propia formación académica. Lo anterior es posible a través de la dinamización de nuevas pedagogías y modelos que invitan a centrarse en el estudiante, mediante relaciones interestructurantes de experimentación y construcción colectiva de conocimiento, con el objetivo de lograr que los actores del proceso educativo trabajen con un enfoque de aprendizaje significativo que les permita promover avances notables en la construcción del conocimiento. Un ejemplo de ello es la estrategia de Aula Invertida, estrategia que se resalta en esta revisión documental como un método de gran utilidad para que, en mediación con el saber disciplinar, en este caso, la química, se convierta en una nueva posibilidad de interacción y aprendizaje en el acto educativo. Se esperan resultados que reflejen un trabajo más independiente, seguro y con mayor apropiación de los contenidos, gracias a la disponibilidad de nuevos e innovadores recursos tecnológicos. Además, se resalta la importancia de promover estos ambientes virtuales en la educación, mediante la implementación de herramientas TIC, para dar respuesta al desafío que representan constantemente los entornos del aula educativa para las nuevas generaciones de estudiantes.
Expanding the Scope of Bayesian Argumentation
Authors: Hahn Ulrike
Published: September 2024

A Bayesian approach to argumentation has, arguably, made great strides in illuminating long-standing questions about argument quality. In particular, the Bayesian framework allows nuanced evaluation of content-based differences in argument strength for individual arguments –both for arguments about facts and for practical arguments. It also provides a principled approach to summary evaluation in contexts of multiple, both mutually supporting and competing arguments, in final reckoning. What it has not done, however, is contribute systematically to an understanding of the dialectical process of argumentation, either in dyads or across large collectives. The talk reviews the literature on argument quality, but then focusses on recent work within the Bayesian framework to address this dialectical challenge.
Extending Dialectical Classical Logic Argumentation with Unrestricted Rebut and Occam Razor Defeats
Authors: D’Agostino Marcello , Modgil Sanjay
Published: September 2024

Dialectical Classical Logic Argumentation (D-Cl-Arg) formalises maxi-consistent non-monotonic reasoning under the practical assumption that agents have bounded resources for classical inference, and that agents do not typically check arguments’ premises for subset minimality and consistency. However, D-Cl-Arg still satisfies all rationality postulates. Moreover D-Cl-Arg accommodates uses of argument characteristic of dialectical practice. This paper extends D-Cl-Arg to accommodate further dialectical uses of argument; in particular unrestricted rebuts on the deductively derived conclusions of arguments, and Occam Razor defeats that dialectically demonstrate that an argument makes use of redundant premises. We show that all rationality postulates are still satisfied, while relaxing constraints on preference relations that were previously required to prove rationality.
Related Explanations in Formal Argumentation, an Empirical Study
Authors: Scheffers Roos , Bex Floris , Borg AnneMarie
Published: September 2024

In formal argumentation theory, multiple argumentation-based explanation methods have been formulated based on ideas from social and cognitive science. However, these have not yet been empirically validated. One such idea is that information in an explanation needs to be related; in argumentation-based explanations, this has been captured as there being an attack path between arguments. This study describes and empirically validates two types of relatedness, related admissibility and directly related admissibility. This was done by instructing participants to select arguments from an argumentation framework to explain another argument in this framework. These explanations selected by the participants were compared to argumentation-based explanations that use relatedness. We found that both forms of relatedness are cognitively plausible. This gives insight into how argumentation theory can be applied in the real world to provide explanations.
Defining Argumentative Discourse Units as Clauses: Psycholinguistic Evidence
Authors: Seyfried Clara , Reed Chris , Kamide Yuki
Published: September 2024

Identifying the smallest units of human argumentation remains a key challenge for computational models of argument. This study tested the assumption that argumentative discourse units (ADUs) can be best described as clauses. Two online experiments investigated the role of ADUs in human language processing (Experiment 1) and recall (Experiment 2), providing evidence that discourse comprehension might be influenced by syntactic depth. Experiment 1 analysed participants’ cued recall of pairs of clauses to identify whether they relied on clausal units when encoding information. Experiment 2 tested effects of manipulating the syntactic complexity (natural language – varying complexity, elementary language – one clause per sentence, or atomic language – one sub-clausal unit of information per sentence) on participants’ free recall of short encyclopaedic entries adapted from Wikipedia. Both experiments found small-to-medium effects suggesting that defining ADUs as clauses might be justified to a degree, with potential implications for computational models of human argumentation.
Leveraging Semantic Model and LLM for Bootstrapping a Legal Entity Extraction: An Industrial Use Case
Authors: Breton Julien , Billami Mokhtar Boumedyen , Chevalier Max , Trojahn Cassia
Published: September 2024

Compliance with legal documents related to industrial maintenance is the company’s obligation to oversee, maintain, and repair its equipments. As legal documents endlessly evolve, companies are in favour of automatically processing these texts to facilitate the analysis and compliance. The automatic process involves first, in this pipeline, the extraction of legal entities. However, state-of-the-art, like BERT approaches, have so far required a large amount of data to be effective. Creating this training dataset however is a time-consuming task requiring input from domain experts. In this paper, we bootstrap the legal entity extraction by levering Large Language Models and a semantic model in order to reduce the involvement of the domain experts. We develop the industrial perspective by detailing the technical implementation choices. Consequently, we present our roadmap for an end-to-end pipeline designed expressly for the extraction of legal rules while limiting the involvement of experts.
Stitching Gaps: Fusing Situated Perceptual Knowledge with Vision Transformers for High-Level Image Classification
Authors: Martinez Pandiani Delfina Sol , Lazzari Nicolas , Presutti Valentina
Published: September 2024

The increasing demand for automatic high-level image understanding, including the detection of abstract concepts (AC) in images, presents a complex challenge both technically and ethically. This demand highlights the need for innovative and more interpretable approaches, that reconcile traditional deep vision methods with the situated, nuanced knowledge that humans use to interpret images at such high semantic levels. To bridge the gap between the deep vision and situated perceptual paradigms, this study aims to leverage situated perceptual knowledge of cultural images to enhance performance and interpretability in AC image classification. We automatically extract perceptual semantic units from images, which we then model and integrate into the ARTstract Knowledge Graph (AKG). This resource captures situated perceptual semantics gleaned from over 14,000 cultural images labeled with ACs. Additionally, we enhance the AKG with high-level linguistic frames. To facilitate downstream tasks such as AC-based image classification, we compute Knowledge Graph Embeddings (KGE). We experiment with relative representations [1] and hybrid approaches that fuse these embeddings with visual transformer embeddings. Finally, for interpretability, we conduct posthoc qualitative analyses by examining model similarities with training instances. The adoption of the relative representation method significantly bolsters KGE-based AC image classification, while our hybrid methods outperform state-of-the-art approaches. The posthoc interpretability analyses reveal the visual transformer’s proficiency in capturing pixel-level visual attributes, contrasting with our method’s efficacy in representing more abstract and semantic scene elements. Our results demonstrate the synergy and complementarity between KGE embeddings’ situated perceptual knowledge and deep visual model’s sensory-perceptual understanding for AC image classification. This work suggests a strong potential of neurosymbolic methods for knowledge integration and robust image representation for use in downstream intricate visual comprehension tasks.
