El efecto del gasto en campaña en candidaturas de partidos institucionalizados y de grupos emergentes: convencionales constituyentes en Chile en 2021
Authors: Abarca Olave Thomas , Navia Patricio
Published: December 2024

A partir de la evidencia que muestra que el gasto en campaña rinde más para los candidatos no incumbentes, en elecciones sin incumbentes en que candidatos que militan en partidos institucionalizados compiten contra candidatos de partidos emergentes e independientes el efecto del gasto debiera ser menor para los primeros, que gozan de más reconocimiento de nombre. Con datos de los 1278 candidatos a convencionales constituyentes que compitieron en Chile en 28 distritos de representación proporcional y lista abierta por 138 escaños de la convención constitucional en mayo de 2021, evaluamos dos hipótesis sobre los determinantes del éxito electoral. Reportamos un efecto positivo general del gasto, pero un mayor gasto tiene un efecto de interacción negativo en el éxito electoral de las candidaturas de partidos institucionalizados de izquierda y de derecha. El gasto en campaña rindió más en candidaturas de partidos y grupos emergentes que en las de partidos institucionalizados.

AN EXPLORATION OF SPEAKING ANXIETY OF ENGLISH MAJOR FIRST-YEAR STUDENTS AT A PUBLIC UNIVERSITY IN HANOI
Authors: Thi Bich Nguyen Dao , Thuy Duong Nguyen
Published: December 2024

The study investigates the speaking anxiety experienced by first-year English majors. 152 first-year English majors at a public university in Hanoi participated in the questionnaire. The results show that participants had a medium level of English-speaking anxiety. Factors contributing to this anxiety include students’ negative self-assessment of ability, self-comparison to others, fear of negative evaluation, fear of being in public, and shyness. Additionally, the nature of teachers' questions, lack of preparedness, and beliefs about native speakers or instructors also contribute to speaking anxiety. The study highlights that students experienced higher anxiety during presentations compared to group discussions or paired interviews. Besides, the majority of first-year students believed that instructors’ behavior and characteristics would play a significant role in reducing their speaking anxiety in class. The study offers valuable insights into students’ speaking anxiety for English lecturers to support students in managing speaking anxiety effectively.
EMBEDDED ADJECTIVES IN CHINESE AND VIETNAMESE QUANTITATIVE NOUN STRUCTURES FROM A COGNITIVE PERSPECTIVE
Authors: Thi Hong Nhung Hy
Published: December 2024

From a cognitive perspective, this paper provides an in-depth analysis of the embedded adjectives in the structure of Chinese and Vietnamese quantitative nouns. It employs the theory of distance iconicity and image schema to reveal the cognitive strategies of these languages. The conceptual components within the structure of numeral classifiers are close, and thus they should also be close in language form. Conversely, the conceptual components in the structure of collective classifiers and container classifiers are distant from each other, and therefore, they can be separated in language form. Additionally, when the image is perceived as a whole, the cognitive strategy of summary scanning is adopted. When the image can be decomposed into processes, the cognitive approach of sequential scanning is adopted. There are many syntactic differences between Chinese and Vietnamese in such structures, but certain cognitive rules can still be identified. In the future, we will strive to provide more comprehensive summaries and natural explanations of the language structures of Chinese and Vietnamese, particularly the syntactic structures.

Authors: Duc Nguyen Mau , Nguyen  Vinh Quang  , Nguyen Hoang Kien  , Cao Thi Van Giang  , Ngo Gia Khanh  , Le Thi My Quyen
Published: December 2024

In the digital transformation era, the integration of Information Technology in education is pivotal. Augmented Reality (AR), with its capacity to visualize abstract concepts, is increasingly recognized as a valuable tool in Chemistry education. The abstract nature of general Chemistry content, like the visualization of atoms and molecules, poses significant comprehension challenges for high school students. This study aims to investigate the effectiveness of AR in enhancing the understanding of general Chemistry among high school students using the Technological Pedagogical Content Knowledge (TPACK) model. The research data included 90 high school chemistry teachers from high schools in four northern provinces, collected through classroom observations and surveys using a 5-point Likert scale; the data were analyzed using both descriptive and inferential statistics. The findings indicate significant improvements in students' understanding of Chemistry when taught using AR-integrated lessons designed with the TPACK model. Students demonstrated enhanced engagement, better conceptual grasp, and increased satisfaction with the learning process. AR technology, when integrated with the TPACK framework, substantially enhances the learning of general Chemistry in high schools. This study supports the broader application of AR in educational settings to improve the effectiveness of teaching and learning processes.
Arbitraje e interpretación contractual en el derecho ecuatoriano
Authors: Coronel Jones César
Published: December 2024

Con enorme frecuencia las controversias sometidas a arbitraje se relacionan con la interpretación contractual, e imponen a los árbitros la carga de realizarla. Las normas del Código Civil y las explicaciones de la doctrina marcan pautas fundamentales en dicho proceso. La interpretación, la calificación y la integración del negocio jurídico, permiten establecer la “regla negocial”. Para su determinación, el texto, la intención común de las partes y la naturaleza del contrato son esenciales; pero también lo son la buena fe, como estándar objetivo de conducta y la carga de hablar claro que pesa sobre los redactores del contrato. La interpretación lógica sistemática, por su parte, es imperativa, pues la intención, que es el espíritu del contrato, es indivisible. El análisis histórico de la relación negocial y la aplicación que las partes hayan hecho del contrato, son otros auxiliares valiosos en la tarea interpretativa, que constituye un verdadero arte. Las normas sobre la materia son una especie de caja de herramientas. Dependiendo del caso, habrá alguna de especial utilidad y las otras servirán de apoyo para confirmar lo apropiado de las conclusiones. En cualquier caso, jamas será aceptable un resultado contrario a la buena fe. Hay principios que se imponen incluso a la intención común de las partes, y este es uno de ellos. El proceso interpretativo, puede revestir considerable complejidad, de allí la conveniencia de aprovechar las luces que brinda la doctrina.

Una propuesta para una diferencia irreconciliable: la ejecución de laudos anulados y el principio de cortesía internacional
Authors: Jijón Andrade Alegría , Orellana Ubidia Adriana
Published: December 2024

Ha existido un largo y sofistificado debate entre la comunidad internacional sobre la posibilidad de ejecutar laudos arbitrales que han sido anulados desde el arbitraje. Diferentes países, incluso diferentes cortes del mismo país, han tomado decisiones distintas y contradictorias sobre este aspecto. El objetivo de este artículo no es resumir los distintos enfoques o decisiones judiciales relacionadas con este tema, pues consideramos que esta tarea ya se ha hecho en miles de artículos académicos, sino que proponemos un enfoque alternativo a la pregunta de si es que es posible y, de ser así, cómo podrían ejecutarse laudos arbitrales en un tercer Estado.
Afectan las medidas reparatorias no pecuniarias ordenadas en un arbitraje de inversión a la soberanía de los Estados? Perspectivas desde la experiencia ecuatoriana
Authors: Larrea Savinovich Andrés , Alarcón Peralta Juan Martín
Published: December 2024

El presente artículo analiza las medidas reparatorias no pecuniarias en el arbitraje internacional de inversiones vis à vis la soberanía de los Estados, haciendo énfasis en casos en los que el Ecuador ha sido parte. Las preguntas a analizar son: ¿Atentan las medidas no pecuniarias dictadas por tribunales de arbitraje de inversión a la soberanía estatal? ¿Cuál es la experiencia del Ecuador en relación a las medidas no pecuniarias en arbitraje de inversión? Para responder estas preguntas, en primer lugar, se analizará la naturaleza de las distintas medidas de reparación en el arbitraje internacional de inversiones. En segundo lugar, se hará un análisis casuístico de los procesos arbitrales en los cuales el Ecuador ha sido parte, para explorar la aplicabilidad de este tipo de reparaciones. Finalmente, se estudiará el concepto de soberanía dentro del ordenamiento jurídico nacional e internacional. Con este análisis, se demostrará que las medidas de reparación no pecuniarias son una alternativa viable en muchos casos y además, constituyen un mecanismo idóneo para preservar la relación entre el Estado y el inversionista.

La oponibilidad de la cláusula arbitral estatutaria frente a terceros ajenos a la compañía en el ordenamiento jurídico ecuatoriano
Authors: Moncayo Rovalino María Camila
Published: December 2024

Los estatutos con los que se rigen las compañías generalmente tratan también la forma en la que estas resolverán sus controversias internamente. De este modo, una práctica que se ha vuelto usual con el paso del tiempo es la de acudir a arbitraje en caso de que exista una controversia entre los socios o accionistas de una compañía. Sin embargo, el alcance de estas cláusulas es limitado. Este artículo analiza los sujetos a los cuales se pueden extender los efectos del convenio arbitral contenido en un contrato de sociedad en el Ecuador, a la luz de las reformas promulgadas en la Ley Orgánica de Emprendimiento e Innovación, que reguló de manera expresa el arbitraje estatutario, y demuestra que esta no es oponible a terceros ajenos a la compañía.
Falta de competencia del Tribunal Arbitral como causal de nulidad del laudo
Authors: Centeno Arteaga Valentina , Morales Solís Ana Belén , Sánchez Romero Romina Isabel
Published: December 2024

La acción de nulidad del laudo arbitral protege el derecho al debido proceso, esto incluye el derecho a ser juzgado por un juez competente. Las partes tienen la facultad de pedir la revisión de la competencia del tribunal arbitral en sede judicial. Al analizar la competencia del árbitro se deben aplicar tres criterios: ratione materiae, ratione personae, ratione voluntatis. Sin embargo, la Ley de Arbitraje y Mediación solo se pronuncia sobre la falta de competencia del árbitro por materia no sometida a arbitraje. Este artículo propone analizar la incorporación de una causal de nulidad expresa por la falta de competencia del árbitro que abarque los tres criterios antes mencionados. Se analizará la utilidad de dicha causal y los obstáculos en su implementación.

Authors: Lopes Veronica Maria Neto , Ferreira Liliane Caraciolo , Ferreira Caliane Borges
Published: December 2024

O estudo teve como objetivo verificar as perdas na comercialização de hortaliças orgânicas: alface (Lactuca sativa), cebolinha (Allium schoenoprasum), coentro (Coriandrum sativum) e couve (Brassica oleracea) entre quatro agricultores que vendem essas verduras na feira do Mercado Municipal de Orgânicos em Petrolina, Pernambuco. A metodologia utilizada foi um estudo de campo exploratório-descritivo com coleta de dados primários nas hortas e durante a realização das feiras. Os resultados da investigação apontaram que o processo pós-colheita das hortaliças, envolvendo limpeza, separação e acondicionamento, é realizado sempre no dia anterior às feiras. Em alguns casos, a embalagem dos produtos é feita após a chegada das hortaliças ao mercado. Os dados também indicaram perdas pós-colheita na comercialização das hortaliças durante as feiras, decorrentes de embalagens inadequadas e da incidência de luz solar sobre algumas bancas, causando o murchamento das verduras.
DATA PRIVACY AND REGULATORY COMPLIANCE IN THE USA: A CALL FOR A CENTRALIZED REGULATORY FRAMEWORK
Authors: Ajayi Olumide
Published: December 2024

ABSTRACT
Considering the recent technological advancements, the study examines the need for centralized data privacy and compliance regulation in the United States of America (USA). The current data privacy landscape in the USA is characterized by a patchwork of federal and state laws, which often lack uniformity and consistency. This has hindered the development of a standardized approach to data protection. Therefore, this study examined the key challenges associated with the current data privacy landscape in the USA and how a centralized data privacy and compliance regulation can address these challenges.
Objective: The study's primary purpose was to examine the plausibility of a unified framework on data privacy within the US and how data can be well-managed.
Method: The study employed a theoretical approach, analyzing existing literature, case studies, and current legal framework to assess the extent of data protection within the United States and make a case for a prompt federal law that would be all-encompassing in the subject matter of data, data privacy, and security.
Results: The study found that the current patchwork of federal and state laws can lead to inconsistencies and business compliance burdens. Additionally, the existing rules may not adequately address emerging privacy challenges, such as those related to artificial intelligence and big data.
Conclusion: The study concluded that centralized data privacy and compliance regulation could significantly enhance data protection in the USA. Thus, such a regulation could provide a more robust, consistent, and practical framework for safeguarding personal data.
Formation of the Noble Class in the System of Political and Legal Values of the Russian Police State
Authors:   Lecturer of the Department of Theory and History of State and Law Named after G.V. Maltsev of the M.M. Speransky Law Faculty of the Institute of Law and National Security, Medvedev Vladimir V.
Published: December 2024

In the system of political and legal values of the police state, class differentiation is an integral element. The functional
purpose of the estates determines the place and methodology in the content of the ʻcommon goodʼ, the amount of corresponding
privileges for the performance of duties. The process of formation of the nobility by Peter the Great was determined by the
fate of the estate ― development trends, the search for resources to protect interests, forms of participation in public life.
In the desire to create a social monolith of diverse groups of serving people in the fatherland, it was necessary to resort to
harsh measures to introduce universal and lifelong, continuous service with the introduction of a new ranking system of
ranks and positions, coercion to receive education and assimilate European culture. The flexibility of class culture allowed the
noble class to be replenished with the best people from the taxable categories of the population while preserving the main
political and legal values, which allowed for a long time to successfully maintain the existing regime.
Editorial Introduction. Ontologies Aren't Essential
Authors: Solnick Rachel , Singleton Aled
Published: December 2024

As geographers attempt to decolonise worldviews and mindsets, Indigenous thinkers have explained the radical anti-colonial praxis existing within their cosmologies, place-thought, and life-ways. Indigenous thought inevitably challenges systemic coloniality and can shift paradigms for all of us. The intention of this Issue of Agoriad: A Journal of Spatial Theory is to uplift decolonial scholarship. Whilst we reckon with our continued complicity in structures that continue to exploit and dispossess Indigenous peoples, we strive to contribute to the transformation of academic thought, through genuine attempts to decolonise.
Book Review: Paulo Basta et al. (Eds.) Pohã ñana: Ñanombarete, tekoha, Guarani ha Kaiowá arandu rehegua
Authors: Essam Alice
Published: December 2024

The publication under review is the product of six-year study initiated by non-indigenous researchers at the public health school within Brazil’s biomedical sciences research institute Fiocruz, in collaboration with indigenous Guaraní-Kaiowá people. The research journey takes the epidemiologists into the Guaraní-Kaiowá community, where they realise that a deeper understanding of traditional healing approaches is needed. Through this engagement, the project of documenting the medicinal plants used by these peoples is born, responding to the political struggles of the Guaraní-Kaiowá, who have been expelled from their ancestral lands. The researchers come to see the medicinal plants as 'not just plants, but also plants', as they gain appreciation for the metaphysical role of plants within Guaraní-Kaiowá cosmology. The work is an interesting tentative exploration of working across languages, cultures, epistemologies, ontologies and cosmologies, and, although not directly intending to, brings the question of ontology to the study of ethnobotany. In this way, it provides a relevant case study for Science and Technology Studies.

Published: December 2024

Bilindiği üzere uygulamalı bilim alanlarında, öğreneğin, mühendislik, tıp, ekonomi, yapay sinir ağları vb. bir çok uygulamalı alanda ortaya çıkan problemlerin matematiksel olarak modellenmesine diferansiyel denklemler karşılık gelmektedir. Bu diferansiyel denklemlerin önemli bir türü is gecikmeli diferansiyel denklemlerdir. Lyapunov anlamında bu tür denklemlerin çözümlerinin karalılık vb. problemleri uygulamalarda önemli bir yere sahiptir. Ancak, genel anlamda gecikmeli diferansiyel denklemleri çözmek pek de kolay değildir, hatta numerik olarak hariç, genel anlamda açıkça çözümleri bulmak imkânsızdır. Bu tür zorluklara rağmen, Lyapunov-Krasovskii fonksiyonel metodu, göz önüne alınan gecikmeli diferansiyel denklemleri çözmeksizin, yani çözümler hakkında herhangi bir ön bilgiye ihtiyaç duymaksızın, çözümlerin kararlılığı vb. davranışları hakkında bilgi edinilmesine olanak tanır.
Bu makalede, birinci mertebeden gecikmeli diferansiyel denklemlerin sürekli zaman sistemlerinin çözümlerinin bazı niteliksel analizleri ele alınmaktadır. Burada belli formda sürekli zaman gecikmeli pertürbe ve pertürbe olmayan diferansiyel denklemler sistemleri sırasıyla göz önüne alınmaktadır. Bu sistemlerin çözümlerinin asimptotik kararlılık, integrallenebilirlik ve sınırlılık davranışları Lyapunov-Krasovskii fonksiyonel metodu yardımıyla incelenmektedir. Elden edilen sonuçların uygulanabilirliğini göstermek için iki örnek verilmiştir. Verilen yeni sonuçlar, geçmiş literatürde elde edilmiş sonuçlardan daha genel niteliktedir
Construcción de portafolios en fondos de inversión considerando momentos estadísticos superiores
Authors: Ossa González Genjis A.
Published: December 2024

Este estudio busca crear portafolios con activos ETF, aplicando un enfoque cuantitativo que incluye momentos estadísticos de orden superior, más allá de la normalidad de la utilidad esperada. El objetivo es optimizar la utilidad y destacar los tres portafolios principales. Al evaluar portafolios con ETF como LABU, PSQ, FXI, SPY e IWM, se notó una reducción en rendimientos al aplicar momentos superiores. El portafolio 2, bajo la hipótesis de normalidad, sobresa­lió por su alta media de rendimiento y baja volatilidad, a pesar de una curtosis elevada. Sin embargo, la inclusión de momentos superiores indicó un aumento del riesgo, lo que hizo que ningún portafolio fuera óptimo para inversión.
Soaking kinetics of quinoa seed (Chenopodium quinoa Willd). Mathematical modeling: Applying analytical and empirical models
Authors: Demarchi Silvana , Giner Sergio Adrian , Torrez Irigoyen Ricardo Martín
Published: December 2024

Quinoa is a nutritionally valuable pseudocereal due to the favorable amino acid profile of its proteins compared to other seeds and grains. The goal of this study was to investigate the soaking kinetics of quinoa seeds. Experimental curves of moisture content versus time were obtained for a water temperature range of 20 ℃ to 70 ℃. Regarding the soaking process empirical equations such as Peleg, Weibull, and Exponential and an unsteady state diffusional model with a strict internal control of the mass transfer rate. Calculations by empirical models were markedly accurate for water uptake with r2 higher than 0.95 and RMSE values lower than 0.09. On the other hand, the complete analytical solution, which involves an infinite convergent series for constant diffusivity (Deff) and constant radius (R0), provided a reliable prediction of soaking kinetics. Values of the diffusion coefficient (around 10−11 m2/s) are within the ranges expected for food rehydration at similar temperatures. The activation energy and pre-exponential factor were calculated by an Arrhenius type-equation. The values determined were Ea = 9.1 kJ mol−1 K−1 and, D0 = 3.861 × 10−10 m2 s−1, respectively with an r2 value lower than 0.8.

Group I treated with normal saline, Group II with 0.8% SRBC as antigen 5th day as sensitizing and 10th day as challenging dose, Group III antigen with methanolic extract of Aloe vera Orally @ 200mg/kg.body wt. consecutive for 5 days during sensitizing and challenging dose. The immunological parameters were evaluated with haemagglutination (HA) test for humoural immune response (HIR) whereas delayed type hypersensitivity (DTH) for evaluating cell mediated immune response (CMIR). DTH was assessed by injecting 1-chloro-2,4-dinitrobenzene (DNCB) in the foot paw region as well as by absolute lymphocyte count. Result: Methanolic extract of Aloe vera gel showed significant effect on humoural immune response as assessed by HA test. Antibody titre were found to be significantly (p less than 0.01) higher in Aloe vera treated group (1.35402 ± 0.205) as compared to antigen treated (0.60201±0.076) group.DTH assessed by injecting 1-chloro-2,4-dinitrobenzene (DNCB) mitogen was also found to be significantly (p less than 0.01) higher in aloe vera treated group (3.012 ± 0.15* mm) as compared to antigen treated (0.482 ± 0.04 mm). Methanolic extract of Gel of Aloe vera exhibited immunomodulatory activity with respect to cell mediated immune response in wistar rats.
Detection of Psychosis by Rorschach Performance Assessment System Variables in Adolescents With Chronic Daily Cannabis Use
Authors: Spores John M.
Published: December 2024

A retrospective sample of 20 adolescents without a history of psychosis was divided into two equal groups of 10: one with daily use of cannabis for 6 or more months and one without any history of cannabis or other substance use. The groups were matched on both sex and age. All 20 adolescents were administered the Rorschach Performance Assessment System (R-PAS), which were all determined to be valid protocols. A series of eight independent samplettests with Cohen’sdeffect sizes were done, along with other descriptive and inferential statistics. Results showed that seven of eight perception and thinking R-PAS variables reliably distinguished between the Cannabis and No Cannabis groups. Further, the Cannabis group showed standard scores falling within either the very high or extremely high interpretive categories for this test, hence manifesting unequivocal signs of psychotic disturbance as operationally defined by the perception and thinking R-PAS variables. Further, the Cannabis group scored approximately two to three standard deviation differences on these R-PAS variables versus the No Cannabis group, hence manifesting consistently large effects. Implications of these findings were discussed, including some limitations of the present study and suggestions for future research.

Published: December 2024

Dans cet article, les auteurs analysent les conditions d'exploitation des forêts dans la zone intertropicale de l'Afrique francophone.Dans cette première partie, les conditions générales sont examinées et précisées. Il apparaît que la forte pluviométrie, l'éloignement des forêts (peu ou mal connues), leur hétérogénéité, le rapport entre les exportations et la production, sont autant de facteurs qui rendent les bois exploités coûteux et font que l'exploitation forestière tropicale est sélective.Ces différents facteurs ont également des conséquences sur la structure de l'exploitation. Dans les grandes entreprises, l'intégration des activités est de plus en plus nécessaire. Le commerce des grumes, la transformation locale et la commercialisation sont liés à l'exploitation forestière proprement dite.

Authors: Sari Indri Widya , Diba Sarah , Nopriyati  , Athuf Thaha  , Raden Pamudji  , Fitriani
Published: December 2024

Background: Atopic dermatitis (AD) is a chronic recurrent skin disease that is very complex due to impaired skin barrier function in the form of xerosis, chronic eczematous lesions, and itching, commonly found in infants and children. Pathogenesis is thought to be the interaction of genetic factors, immune dysfunction, epidermal barrier dysfunction, and the role of the environment and infectious agents. Approach the disease by performing etiopathogenesis algorithms, clinical manifestations, diagnosis, and treatment. Based on the 2013 Asia-Pacific consensus, AD management guidelines using the 5-pillar principle have long been used. Currently, the European consensus in 2018 has developed new guidelines for AD management. Purpose: To provide an updated treatment for AD. Review: The ethiopathogenesis of AD is influenced by genetics, skin barrier disorders, and immune response disorders. Updated management of the European consensus in 2018 includes education, avoidance of precipitating factors, psychosomatic counseling, optimization of skin barrier function with moisturizers, anti-inflammatory and antimicrobial administration, allergen-specific immunotherapy, complementary and alternative drugs, phototherapy, and controlling the itch-scratch cycle with anti-itch in pediatric and adult AD patients.

Biomass-derived carbon-based materials with high performance are expected to become the frontrunners in anodes for potassium-ion batteries because of cost-effectiveness, non-toxic, and ecological compatibility. Herein, this review systematically explores critical parameters during the application of biomass-derived carbon as anodic electrodes for potassium-ion batteries, highlighting material selection, preparation methods, and electrochemical performance. Biomass sources such as plant organs, plant straw, and animal bones offer a cost-effective and renewable route to produce carbon anodes, with unique structural advantages for potassium storage. Key preparation techniques (including pyrolysis, chemical activation, templating, hydrothermal carbonization and microwave-assisted pyrolysis) allow for precise tuning of porosity, surface area, and heteroatom doping, enhancing reversible capacity, rate property, and cycling stability. We further analyze the potassium storage mechanisms, providing insights into the intercalation and adsorption processes that occur during battery operation. However, the mass production before application of these materials is constrained by material selection, preparation processes, and reaction mechanisms. The review also identifies critical challenges for scaling up production, such as consistency in material properties and energy efficiency, and outlines potential solutions, including process optimization and sustainable synthesis techniques. Future research will focus on enhancing the properties of bio-derived carbon anodes through structural and compositional optimization to catch the increasing demands of electrochemical energy storage technologies.

The study explored what students perceived to be the contributing factors to the high failure rate in first-year Accounting. The study followed a quantitative research approach and method informed by a non-experimental survey design. A total number of 82 first-year Accounting students were purposively selected. The survey questionnaire that consisted of closed-ended questions was administered to the respondents. The quantitative data was analysed through SPSS to generate descriptive statistics and provide information about the internal consistency (called the Cronbach Alpha) of the questionnaire Likert scale items used to establish what factors contribute to the high failure rate among undergraduate first-year Accounting students.

The findings revealed that many students were of the view that the instructional techniques used by lecturers did not demonstrate a practical application of Accounting to the students’ lives. Furthermore, the students indicated that Accounting lecturers’ language proficiency did impact their (i.e. the students’) achievement, as poor linguistic competency can result in a communication barrier and ultimately be a factor that influences the high failure rate in first-year Accounting students. An alarm-raising finding was that students indicated that although they enjoyed Accounting and gained personal satisfaction from doing it, they believed that they lacked motivation, which is a crucial influential contributor to high failure rate in the first-year Accounting students.

Understanding how curriculum design choices impact the academic success in terms of grades of students provides valuable insights into the effective delivery of the teaching of introductory financial accounting and economics for students in extended degree programmes (ECP). The main research question asks which delivery model, either foundational modules or augmented main-stream modules, provides an effective pathway to achieving academic success in terms of grades in ECP. Performing a qualitative analysis of a large dataset incorporating 11 410 observations of data of a ten-year period. Analysis of variance was used to identify which delivery model is the most effective in terms of students’ performance. The study provides evidence that introductory modules may provide increased support compared to augmented modules for financial accounting. The study also shows that the use of an introductory module has a significant beneficial effect on extended programme students in their second year in order to achieve academic success in mainstream modules but only in certain cases only if a certain threshold is achieved in the introductory module. This threshold appears to be higher in foundational level economics than financial accounting. The study provides evidence that the choice of delivery model has an impact on financial accounting and economics students’ performance in terms of grades achieved. Foundation modules may benefit from higher required pass grade thresholds so that students in ECP are able to ultimately obtain their degrees.

Encounters with projective identification: Utilising group debrief sessions to contain student teachers’ anxiety
Authors: Auld S. , Haselau T.
Published: December 2024

Teaching experience ‒ in face-to-face, online, and blended educational contexts ‒ provides student teachers with the opportunity to participate in low, mid, and high-resourced schools, in preparation for their integration into the South African educational system. Often, while at low-resource schools, student teachers report feeling ineffectual, frustrated, despondent, and overwhelmed, leading to criticism of the programme, requests to transfer to high-resource alternatives, and threats to disengage from teaching experience. Drawing on Klein’s concept of projective identification, and Bion’s idea of container-contained, we understand such communications as expressions of overwhelming anxiety, highlighting an urgent need for intervention. To address this need, group debrief was incorporated into teaching experience, in an attempt to enable anxiety to be tolerated, worked through, and understood, rather than evacuated defensively via projective identification. Pre- and post-debrief questionnaires were employed to track containment facilitated with fifty (50) final (4th) year student teachers. Though some resistance was expected and noted, the outcomes were largely positive, with most students reporting improved emotional states, reduced anxiety, and feelings of empowerment.

Background and Objectives: Neurodevelopmental disorders (NDDs), including developmental delay (DD), autism spectrum disorder (ASD), intellectual disability (ID), attention-deficit/hyperactivity disorder (ADHD), and specific learning disorders, affect 15% of children and adolescents worldwide. Advances in next-generation sequencing, particularly whole exome sequencing (WES), have improved the understanding of NDD genetics. Methodology: This study analyzed 3244 patients undergoing WES (single, duo, trio analyses), with 1028 meeting inclusion criteria (67% male; age 0–50 years). Results: Pathogenic (P) or likely pathogenic (LP) variants were identified in 190 patients, achieving a diagnostic yield of 13.4% (singleton), 14% (duo), and 21.2% (trio). A total of 207 P/LP variants were identified in NDD-associated genes: 38% were missense (48 de novo), 29% frameshift (26 de novo), 21% nonsense (14 de novo), 11% splicing site (14 de novo), and 1% inframe (1 de novo). De novo variants accounted for 49.8% of cases, with 87 novel de novo variants and 27 novel non-de novo variants unreported in databases like ClinVar or scientific literature. Conclusions: This is the largest study on WES in Colombian children with NDDs and one of the largest in Latino populations. It highlights WES as a cost-effective first-tier diagnostic tool in low-income settings, reducing diagnostic timelines and improving clinical care. These findings underscore the feasibility of implementing WES in underserved populations and contribute significantly to understanding NDD genetics, identifying novel variants with potential for further research and clinical applications.

Interest in advanced echocardiographic imaging methods is growing. The left atrial strain (LAS) is among the recently developed echocardiographic parameters. LAS represents an index of tissue deformation of the left atrium (LA). This parameter is an expression of the LA function. Several arrhythmias depend on the impaired LA function. LAS can be assessed with a resting echocardiogram. The evaluation of LAS during stress echocardiography represents another model for assessing LA function. The development of altered LAS during physical or pharmacological stress is a predictor of early LA disease. Our review aims to evaluate the relationship between the alterations of the LAS and the development of atrial fibrillation (AF), and the diagnostic and prognostic role of the stress echocardiogram in clinical practice.
