Complicações Hepatotóxicas do Paracetamol e a Importância da Atenção Farmacêutica para o uso Racional
Authors: Cardoso Edilsa de Castro , Silva Tallyson Menezes Bento da
Published: October 2024

Introdução: O paracetamol é um dos medicamentos mais utilizados globalmente, sendo comercializado como medicamento isento de prescrição (MIP). Apesar de sua eficácia no tratamento de dor e febre, seu uso inadequado pode resultar em graves complicações hepatotóxicas. Objetivo: Explorar as principais complicações hepatotóxicas associadas ao uso do paracetamol e destacar a importância da atenção farmacêutica na promoção do uso racional deste medicamento. Método: Realizou-se uma revisão narrativa da literatura através de buscas nas bases de dados BVS, PubMed, SciELO e Google Acadêmico, utilizando descritores relacionados ao tema. Foram selecionados 34 artigos publicados entre 2019 e 2024 e sintetizados quatro capítulos. Resultados: A hepatotoxicidade induzida por paracetamol ocorre principalmente através de três mecanismos: overdose, ativação excessiva do sistema enzimático CYP450 e depleção dos níveis de glutationa nos hepatócitos. O papel do farmacêutico mostrou-se fundamental na prevenção dessas complicações, através da educação em saúde e orientação adequada dos paciente. Conclusões: Conclui-se que a hepatotoxicidade induzida por paracetamol representa um relevante problema de saúde pública, agravado pelo fácil acesso ao medicamento e pela prática comum de automedicação. A literatura analisada destaca a complexidade do processo de lesão hepática, envolvendo mecanismos celulares e moleculares como disfunção mitocondrial, estresse oxidativo e ativação do sistema imune inato.
Septic Thrombophlebitis of the Umbilical Vein Complicating an Intrahepatic Umbilical Venous Catheter in a Premature Newborn
Authors: Sanae Azitoune , Kabbaj Khaoula , Saghir Salahiddine , Abilkassem Rachid
Published: October 2024

Septic thrombophlebitis of the umbilical vein (SVT) is a serious pathology in neonates, characterized by inflammation of the umbilical vein due to bacterial infection, with 90% of cases linked to the use of central venous catheters (CVCs). This inflammation can lead to thrombus formation as part of the immune system's response. Premature newborn, 33 weeks gestation, delivered vaginally, with history of gestational diabetes, twin pregnancy, macrosomia and premature rupture of membranes (57 hours), initially well adapted to extrauterine life, with a birth weight of 1575 g. The infant was admitted to neonatology for respiratory distress, and an intrahepatic umbilical catheter was inserted. On the 5th day of hospitalization, the infant developed a nosocomial Klebsiella pneumoniae infection, complicated by a fulminant hemorrhagic syndrome with hematemesis and melena. The clinical course was further complicated by multivisceral failure, requiring hepatic Doppler ultrasound, which revealed umbilical vein thrombosis. The newborn was treated with curative doses of Lovenox, while targeted antibiotic therapy was maintained for three weeks after negative blood cultures, resulting in significant clinical and biological improvement. Based on this case, we conclude that it is advisable to think about umbilical vein thrombosis and to perform an abdominal ultrasound in the presence of any digestive hemorrhage in a newborn or an intrahepatic or peripheral umbilical venous catheter, or in subjects at risk (hypotrophy, polycythemia, transfusion on the catheter) in order to screen for possible umbilical or portal vein thrombosis.
Exploring staff and student experiences of group-work assessment in higher education
Authors: Allen Louise , Warburton Ashli , Adeoye Joanne Marie
Published: October 2024

Group work in higher education is well known to promote deep learning through collaboration with peers. However, there can be issues with facilitation, perceived fairness, and motivation. The aim of this project was to explore staff and student views of a new group presentation assessment. A student survey explored preparation, experiences, and learning/skills. Two academics were interviewed. According to the survey, students felt prepared for the group work, but less so for the presentation. Students also felt their group worked well, although some did not agree that everyone contributed. Most agreed that the task was enjoyable and that they gained new knowledge. Two broad themes arose from the interviews (preparedness and student support), which link to the findings in the survey. Though the assessment format was well received, there was room to develop the support resources. The individual contribution grade for the assessment could include more weight on quality to enhance engagement.

Who is supporting who? Re-imagining Graduate Teaching Assistant training and support in a School of Environmental Sciences
Authors: Brough Stephen
Published: October 2024

Despite the growing use of postgraduate research students as Graduate Teaching Assistants (GTAs) within UK higher education institutes, challenges remain in how to best support these students. This study reports on the GTA experience within a School of Environmental Sciences at a research-intensive UK university. Specifically, the study explores GTA training opportunities and support provision. Findings were drawn from surveys of GTAs and academic staff. Responses revealed that whilst GTAs made a wide range of valuable contributions to teaching, they and academic staff were often unsure or unaware of (i) their individual responsibilities, and/or (ii) development opportunities already available. These barriers have the potential to influence GTAs’ confidence in their ability to teach and can reduce their sense of identity within the school. Based on these findings, suggested areas for action are discussed in a bid to further embed good practice in the use of GTAs within the school.

Three new species of plexippine jumping spiders (Salticidae, Salticinae, Plexippini) from dry forest in Boeny region, north-western Madagascar
Authors: Murray Katie I. , Escobar-Toledo Jaime , Pett Brogan L.
Published: October 2024

Despite being the most diverse family of spiders, Salticidae (jumping spiders) are poorly studied in Madagascar with only 47 of the total 105 species recorded in the last 100 years. Here, we describe three new species of Plexippini Simon, 1901 from dry forests in North-western Madagascar as part of an ongoing biomonitoring programme. This paper increases the number of species in the genus Evarcha Simon, 1902 from 93 to 95 and Thyene Simon, 1885 from 55 to 56. Additionally, we publish specimen records of Plexippus petersi (Karsch, 1878) from Madagascar for the first time. All new species are diagnosed and illustrated through photographs and drawings.
Possible effects of shipping routes on coral reef degradation and diversity in Karimunjawa Marine National Park, Java Sea
Authors: Sabdono Agus , Wijayanti Diah Permata , Hilmi Muhammad , Satya Eridhani Dharma
Published: October 2024

The Karimunjawa Marine National Park, situated in the Java Sea, Indonesia, is renowned for its rich biodiversity and lively coral reefs. However, amidst the backdrop of this natural beauty, concerns have been raised regarding the potential impacts of shipping activities on the health and diversity of these fragile ecosystems. The increase in maritime traffic, including commercial vessels, tourist boats, and fishing vessels, traversing through the Karimunjawa Marine National Park, raises significant environmental concerns. The movement of these vessels, especially along specific shipping routes, has the potential to disturb and damage coral reefs through various mechanisms. Hence, this study aimed to investigate the possible impacts of shipping routes on the coral abundance and diversity and the coral health in the Karimunjawa Islands, Java Sea, Indonesia.

This study categorized ship routes into West Route, East Route, and Non-Route and assessed coral health and diversity across 15 islands. Key metrics analyzed included coral disease prevalence, coral cover, diversity index, species richness, relative abundance, and evenness, using 15 × 2 m belt transects at 3 and 8 m depths with three repetitions each.

Statistical analysis revealed significant differences in coral abundance and species richness among ship-route groups, but no significant depth-related differences. These results suggest that while shipping routes affect certain aspects of coral health and diversity, other factors may be more influential in shaping coral disease prevalence and overall diversity in Karimunjawa reefs.
Experimental evidence of negative agricultural impacts and effectiveness of mitigation strategies of invasive green iguanas (Iguana iguana) in Puerto Rico
Authors: De Jesús Villanueva Christina N. , Massanet Prado Gabriela P. , Van Belleghem Steven M. , Gould William , Kolbe Jason J.
Published: October 2024

Losses in crop yield due to invasive insects, weeds, pathogens, and herbivores cost trillions of dollars per year globally. To prevent further spread of invasive agricultural pest species, continuous monitoring and prevention are crucial. Once introduced, however, assessing the impact of an invasive pest on agricultural production and testing management strategies are essential. The green iguana (Iguana iguana), a globally widespread invasive herbivore, is considered a possible agricultural pest although no quantitative data on its impact are available. In this study, we evaluated the impact of the invasive green iguana on cucumber (Cucumis sativus, var. Dasher II) and lettuce (Lactuca sativa, var. Black-seeded Simpson) yield by testing the efficacy of two management strategies – Neem-based pesticide and mesh fencing – compared to open field cultivation in Puerto Rico. Mesh fencing led to 20% more growth and doubled cucumber yield compared to open field cultivation, while spraying Neem led to an 18% increase in plant growth but no effect on cucumber yield. We found no difference in lettuce growth or yield among treatment and control plots. This study supports categorizing the green iguana as an invasive agricultural pest species and demonstrates the reptile’s potential to reduce crop yield. It also shows that Neem application at the manufacturer’s suggested concentration is not an effective mitigation technique for reducing crop loss due to green iguana herbivory. Government agencies in regions where the green iguana has the potential to be introduced should consider the species a threat to food production when developing monitoring programs and drafting regulations.

Published: October 2024

Stress can significantly affect an individual's mental and physical well-being. Acute stress response of the body is associated with activation of various organ systems, resulting in the release of cortisol and catecholamines. Acute stress response subsides on the resolution of the precipitating stimulus. The persistence of the precipitating stimulus results in chronic stress and burn-out. Longitudinal studies have shown that chronic stress can result in both mental and physical health outcomes. The mental health outcomes include depression, anxiety, post-traumatic stress disorder, substance use disorder etc. The physical health outcomes include effects on multiple organ systems. It is, therefore, essential to identify and rectify the precipitating factors to minimize the impact of stress on the human body.

Published: October 2024

Research on depression, suicidality, substance use disorders, and other mental health conditions in physicians and physicians-in-training reveals that these professionals struggle with higher rates of these potentially impairing conditions than the general population. Multiple regulatory bodies are involved in the assessment and treatment of impaired physicians, including the Federation of State Medical Boards of the United States, Physician Health Programs (PHPs), and individual state medical boards. States vary in their language of assessment, implementation of PHP components, and resulting outcomes. This article summarizes research on the impact of different state approaches to reporting requirements and treatments, and the impact of not reporting impairment.

Authors: Mathews Therese , Burge Stephanie , Reed Jill , Emerson Margaret , Kupzyk Kevin
Published: October 2024

Background

Integrated behavioral health care (IBH), a team-based approach to care, involves behavioral health providers (BHP) to be utilized in primary care settings. Unfortunately, many BHP and primary care advanced practice nursing students do not receive IBH content in their educational curriculum. This article describes an innovative interprofessional simulation project (ISP) in a virtual IBH setting with primary care nurse practitioner and master's level counseling students.

Method

The ISP involved students role-playing using case studies while enacting the roles exemplified in the Collaborative Care model (CoCM). Interprofessional faculty collaborated in developing the project and training facilitators and interprofessional students.

Results

Of the students and faculty who completed a postsurvey, 87.7% reported an increase in preparedness in learning the CoCM, and 92.6% responded the preparation time for the project was “appropriate.”

Conclusion

The ISP project resulted in high satisfaction and perceived increased preparedness for students and faculty to practice and teach IBH.

Orbital Myositis and Strabismus: Clinical Profile, Management, and Predictive Factors for Recurrence
Authors: Lasrado Adeline Shona , Chattannavar Goura , Jakati Saumya , Mohamed Ashik , Kekunnaya Ramesh
Published: October 2024

Purpose

To study the clinical profile of patients with orbital myositis and their management modalities and predictive factors for recurrence.

Methods

The records of all consecutive patients diagnosed as having orbital myositis from 2010 to 2022 were reviewed. Patient demographics, presenting complaints, visual function, primary gaze deviation, and extraocular muscle involved were studied in the clinical profile. The radiological modalities and their management along with the recovery status and need for surgical intervention were documented.

Results

Fifty-two patients (55 eyes) (69% women) were diagnosed as having orbital myositis with a mean age of 36 ± 16 years presenting with periocular pain (55%) followed by diplopia (49%). Disease was unilateral in 94%. Sixty percent had ocular misalignment in primary gaze. The medial rectus was the most involved muscle (58%), with abduction limitation in 73%. Computed tomography (42%), magnetic resonance imaging (42%), and combined imaging (16%) were used in localizing the disease. Muscle biopsy was done in 38% of patients. Systemic immunomodulators were required in 16%. Strabismus surgery was planned in 15% of patients and done in 11%. Recurrence was noted in 43%. Abrupt cessation of steroids was a significant risk factor in recurrence of the disease (
P
= .046). Recovery was partial in 44% of patients and complete in 47%.

Conclusions

Systemic steroids with slow taper has satisfactory outcomes in orbital myositis. Patients refractory to treatment ideally should undergo biopsy and begin taking steroid-sparing agents. Once the disease is in remission, residual disease can be surgically treated for better functional outcome.

La carne, entre “estructuralismo” y literatura
Authors: Colombo Agustin
Published: October 2024

En Las confesiones de la carne Foucault define la carne cristiana como una experiencia histórica en la que se desarrollan prácticas en función de las cuales los individuos pueden modificarse a sí mismos. ¿Sobre la base de qué elementos Foucault construye este enfoque de la carne cristiana? Nuestra hipótesis es que la definición de la carne como una “experiencia” supone una articulación entre algunas nociones propias del estructuralismo —estructura y sistema— y el enfoque de la “experiencia interior” elaborado por Georges Bataille. De este modo, la carne reedita los intentos de elaboración conceptual de la “experiencia” que Foucault había desplegado en los años sesenta. Sin embargo, al definir a la carne como una experiencia de transformación de sí mismo, Foucault introduce una modificación notable respecto al estatus del sujeto. Dicha modificación suscita algunos interrogantes que, a nuestro juicio, permanecen aún abiertos.
Unique continuation for differential inclusions
Authors: De Philippis Guido , Guerra André , Tione Riccardo
Published: October 2024

We consider the following question arising in the theory of differential inclusions: Given an
elliptic
set

\Gamma

and a Sobolev map

u

whose gradient lies in the quasiconformal envelope of

\Gamma

and touches

\Gamma

on a set of positive measure, must

u

be affine? We answer this question positively for a suitable notion of ellipticity, which for instance encompasses the case where

\Gamma \subset \mathbb{R}^{2\times 2}

is an elliptic, smooth, closed curve. More precisely, we prove that the distance of

\mathrm{D}u

to

\Gamma

satisfies the strong unique continuation property. As a by-product, we obtain new results for non-linear Beltrami equations and recover known results for the reduced Beltrami equation and the Monge–Ampère equation: concerning the latter, we obtain a new proof of the

W^{2,1+\varepsilon}

-regularity for two-dimensional solutions.
A convergence result for the derivation of front propagation in nonlocal phase field models
Authors: Patrizi Stefania , Vaughan Mary
Published: October 2024

We prove that the mean curvature of a smooth surface in

\R^{n}

,

n\geq 2

, arises as the limit of a sequence of functions that are intrinsically related to the difference between an

n

- and

1

-dimensional fractional Laplacian of a phase transition. Depending on the order of the fractional Laplace operator, we recover the fractional mean curvature or the classical mean curvature of the surface. Moreover, we show that this is an essential ingredient for deriving the evolution of fronts in fractional reaction-diffusion equations such as those for atomic dislocations in crystals.

Authors: Sccoti Anderson Augusto Volpato , Pereira Susana , Bateira Carlos Valdir Meneses , Robaina Luis Eduardo de Souza , Trentin Romario
Published: October 2024

Hydrological information is essential for estimating the magnitude of floods, thus helping reduce losses and damage. However, when this data is scarce, it challenges flood modeling and risk assessment. In Brazil's west of Rio Grande do Sul, we used the Santa Maria hydrographic basin as a case study to estimate the river flow for different RP based on the statistical distribution of rainfall and river flow data and to simulate flood scenarios using a 2D IBER hydrological model.River flow estimates for 5, 10, 20, 30, and 50-year RP were obtained using the Giandotti equation. The results showed a high correlation between the river flows calculated from rainfall and the fluviometric data, using GEV and GumbelMax distribution. The areas susceptible to flooding are consistent with past flood events, validated with fieldwork and Sentinel imagery. River flows estimated from rainfall data can promote hydrological studies where fluviometric data is absent. Keywords: River Flow Estimation; Generalized Extreme Values; Flood Susceptibility; Rosário Do Sul; Brazil.

Critical Mass: The One Thing You Need to Know About Green Cars
Authors: Leach Felix , Molden Nick
Published: October 2024

In an era where climate change dominates global discourse, Felix Leach and Nick Molden dive deep into the complexity of vehicle emissions in their groundbreaking new book. Building on the insights from Felix’s previous work, Racing Toward Zero, this new release confronts the bewildering landscape of automotive pollution with a clear, rigorous approach: what one piece of information can best describe the environmental impact of cars? Our digital age bombards us with information, yet meaningful understanding often eludes us, particularly when it comes to climate issues like road vehicle emissions. As simple solutions to such a complex problem remain elusive, Leach and Molden advocate for a sophisticated, yet accessible perspective. They propose a radical simplification of how we consider the environmental impact of cars and explore the multifaceted impacts of various vehicle powertrains, pushing beyond CO2 emissions to address broader environmental and societal concerns. The authors introduce the Molden-Leach Conjecture, a bold, universal solution that evaluates vehicles through a holistic lens. This conjecture offers a comprehensive framework to assess and regulate environmental impact, aiming to simplify complex choices for consumers and policymakers alike. They propose a new paradigm for taxing vehicles as we move away from fossil gasoline and diesel, enabling policymakers to address pollution and underpin tax revenues simultaneously. In a world where climate action is critical yet convoluted, Leach and Molden’s book promises clarity and actionable insight. It’s not just about finding answers—it’s about finding the right ones. Join the journey to demystify automotive emissions and drive meaningful change. “As a former Secretary of State for the Environment and, later, Industry I welcome this contribution to the most important challenge of our time.” Michael Hesletine, former Deputy Prime Minister of the United Kingdom
Two high capacity text steganography schemes based on color coding
Authors: Karnel Sadie Juvet , Moyou Metcheka Leonel , Ndoundam René
Published: October 2024

Text steganography is a mechanism of hiding secret text message inside another text as a covering message. In this paper, we propose a text steganographic scheme based on color coding. This includes two different methods: the first based on permutation, and the second based on numeration systems. Given a secret message and a cover text, the proposed schemes embed the secret message in the cover text by making it colored. The stego-text is then send to the receiver by mail. After experiments, the results obtained show that our models perform a better hiding process in terms of hiding capacity as compared to the scheme of Aruna Malik et al. on which our idea is based.

La stéganographie textuelle est un mécanisme permettant de cacher un message secret dans un texte. Dans ce papier, nous proposons un schéma stéganographique basé sur le codage de couleurs. Ce schéma comprend deux méthodes différentes : la première, basée sur les permutations et la seconde, basée sur les systèmes de numération. Etant donné un message secret et un texte de couverture, les méthodes proposées cachent le message secret dans le texte de couverture en le coloriant. Le stégo-texte est ensuite envoyé au destinataire par mail. Après expérimentations, les résultats obtenus montrent que nos modèles proposent un meilleure capacité d'embarquement par rapport au schéma d'Aruna Malik et al. sur laquelle repose notre idée.
Application of the multilingual acoustic representation model XLSR for the transcription of Ewondo
Authors: Yannick Yomie Nzeuhang , Paulin Melatagia Yonta , Benjamin Lecouteux
Published: October 2024

Recently popularized self-supervised models appear as a solution to the problem of low data availability via parsimonious learning transfer. We investigate the effectiveness of these multilingual acoustic models, in this case wav2vec 2.0 XLSR-53 and wav2vec 2.0 XLSR-128, for the transcription task of the Ewondo language (spoken in Cameroon). The experiments were conducted on 11 minutes of speech constructed from 103 read sentences. Despite a strong generalization capacity of multilingual acoustic model, preliminary results show that the distance between XLSR embedded languages (English, French, Spanish, German, Mandarin, . . . ) and Ewondo strongly impacts the performance of the transcription model. The highest performances obtained are around 69% on the WER and 28.1% on the CER. An analysis of these preliminary results is carried out andthen interpreted; in order to ultimately propose effective ways of improvement.

Les modèles auto-supervisés récemment popularisés apparaissent comme une solution au problème de la faible disponibilité des données grâce à un transfert d'apprentissage parcimonieux. Nous étudions l'efficacité de ces modèles acoustiques multilingues, en l'occurrence wav2vec 2.0 XLSR-53 et wav2vec 2.0 XLSR-128, pour la tâche de transcription de la langue Ewondo (parlée au Cameroun). Les expériences ont été menées sur 11 minutes de discours construits à partir de 103 phrases lues. Malgré une forte capacité de généralisation du modèle acoustique multilingue, les résultats préliminaires montrent que la distance entre les langues intégrées dans le XLSR (anglais, français, espagnol, allemand, mandarin, . . .) et l'ewondo a un impact important sur la performance du modèle de transcription. Les performances les plus élevées obtenues sont de l'ordre de 69% pour le WER et de 28.1% pour le CER. Une analyse de ces résultats préliminaires est effectuée et interprétée afin de proposer des pistes d'amélioration efficaces.
The Journey Starts Now: Infusing Peace Education into LO Teaching in South African Secondary Schools
Authors: Ndwandwe Ntokozo Dennis
Published: October 2024

Peace education as part of the school curriculum can transform school functioning by equipping learners with conflict resolution skills. Currently peace education is not part of the existing curriculum in South Africa. Literature indicates that peace education can be appropriately integrated into the compulsory subject, Life Orientation (LO), in South African secondary schools. Informed by Danesh’s integrative peace theory and the extant literature on peace education, a qualitative study explored the possible integration of peace education into LO to assist learners develop conflict resolution skills. Six teachers who teach LO in two secondary schools in the Western Cape, South Africa, which have implemented an extramural peace education programme through the agency of a non-governmental organisation, were purposefully selected. Data were gathered in focus group interviews with the teachers and thematic analysis carried out. Findings of the study highlight the significance of integrating peace education in LO in order to foster a more peaceful schooling environment. Furthermore, aspects of peace education already overlap or complement topics taught in LO, such as respect and tolerance for diversity. Barriers to effective integration of peace education in the LO curriculum are lack of targeted teacher training, rigid curriculum design, teachers’ workload and poor resource allocation. It was recommended that the integration of peace education in LO be prioritised and that the LO curriculum should be expanded to accommodate more explicit themes of peace education. Implementation should be supported through targeted teacher training, attention to teachers’ work schedules, additional teaching time and allocation of appropriate resources.

Published: October 2024

The study utilized a qualitative case study research design entailing an in-depth exploratory examination of principals' leadership competencies and their impact on educational excellence within the O R Tambo Inland education district. Semi-structured interviews were conducted with five principals selected from secondary schools in the district. A convenient sampling technique was used to select the participants from whom empirical data were gathered. A narrative analysis was employed to analyze the collected data, allowing for a comprehensive understanding of the principals' experiences, perspectives, and practices regarding leadership competencies and their implications for educational excellence. The findings revealed that principals play a pivotal role in shaping the school's image and reputation, attracting learners, families, and talented educators through positive attributes and effective leadership practices. Clear and measurable academic objectives aligned with the school's mission and vision are emphasized as essential for guiding educational endeavors and promoting continuous improvement. Thus, the study recommended that a collaborative approach to decision-making, professional development, and community engagement is essential for creating supportive and inclusive learning environments that empower students to thrive academically and personally.
Engineering Academics and Students’ Views on the Phases of Teaching and Learning of Engineering Mathematics in an Antenna Design Course
Authors: Fasinu Vojo George , Machaba Masilo France
Published: October 2024

An antenna design course, naturally, aims to teach students to produce an antenna device, which is a vital tool in technological development. Typically, this course is taught and designed in an abstract manner, which may be an inappropriate approach to teaching it. This approach could be due to engineering academics and students’ poor understanding of how to model mathematics concepts. As a result, antennae experts suggest that antenna technology is a difficult device when it comes to mathematical descriptions, which has resulted in a sudden loss of interest among students in a school of engineering. Thus, this paper reports on the four phases of teaching antenna design using mathematical modelling approaches, with the specific aim of resolving the difficulties encountered in teaching an antenna design course. In achieving this teaching, the study explains the approaches and impact of teaching Mathematical Modelling (MM) in antenna design among engineering academics. In this study, the sample population included one engineering academic and four engineering students. The data were collected using a qualitative research approach, utilising an interview guide and an open-ended questionnaire. Finally, the results of this study confirmed the four major phases of teaching antenna design using engineering mathematics.
Fostering Inclusivity: A Critical Emancipatory Approach to Dyscalculia in Primary School Mathematics
Authors: Mokotjo Lindiwe Gloria
Published: October 2024

This research endeavoured to revolutionise primary school mathematics education by implementing an active learning approach tailored to addressing dyscalculia. The study used a critical emancipatory framework as the theoretical foundation, and participatory action research as the chosen methodology. The researcher employed purposive sampling to select two mathematics teachers, one school-based teacher, a district education psychologist, two learners displaying dyscalculia symptoms, and two parents. The research collaboratively engaged participants to identify challenges, crafting interventions, and reflecting on outcomes through the lens of the critical emancipatory framework and participatory action research,. The researcher assessed the effectiveness of the active learning strategy to enhance students’ mathematical abilities, self-efficacy, and attitudes toward mathematics. Critical discourse analysis shed light on the potential of active learning strategies to improve mathematical learning outcomes and create a supportive learning atmosphere. The results indicated that the implemented active learning strategy offers effective pedagogical practices for learners with dyscalculia by influencing positive changes in their attitude towards mathematics and the learning environment. The participating teachers gained insights into understanding the behaviour of learners with dyscalculia and the role of active learning in intervention strategies. The study’s findings can guide educators, policymakers, and researcher in developing inclusive mathematics instruction for diverse learners in primary school classrooms.
Conceptualization of student support by university support staff in an open distance e-learning environment
Authors: Pitsoane Enid Manyaku
Published: October 2024

Student support is seen as a necessity to better students’ progress. For students to succeed when studying at a distance, they need a great deal of support to adjust to the institution of higher learning. Independence theory was used as a lens to understand the role of student support staff in providing services to students. A qualitative case study was employed with a purposive sample of sixteen support staff to explore the role of regional academic coordinators, counsellors, centre managers and librarians, referred to as support staff, in supporting students in an open distance e-learning institution and also to determine their understanding of student support. The results reveal that most of the support staff members were aware of their role in contributing to student success in the institution. They indicated that there is a gap between academics and professional staff where a referral system is lacking to fully support and trace students needing support.  Support staff seemed to lack marketing skills to inform and attract students to utilize the services. The results further reveal a lack of technological skills among some of the support staff to facilitate online services for students. The study recommends collaboration among all role players in the institution in order to give holistic support to students and to be trained in technological skills to assist students online.

Published: October 2024

Slido is an interactive online platform facilitating active learning in rural university settings. Rural universities often need more resources, including access to technology and opportunities for diverse pedagogical approaches. Traditional lecture-based teaching predominates due to these constraints, which can hinder student engagement and learning outcomes. Slido offers a solution by leveraging technology to enhance interaction, collaboration, and participation within the classroom environment. This study, therefore, adopted the Slido application to promote active learning in one of the rural university classrooms within South African higher education. Active learning methodologies have gained widespread recognition for their effectiveness in engaging students, fostering more profound understanding, and promoting critical thinking skills. However, implementing such strategies, especially in rural university classrooms, can pose unique challenges. Through features such as live polls, quizzes, and audience Q&A sessions, Slido enables instructors to create dynamic learning experiences that encourage active participation from students. In rural contexts where class sizes may be smaller and student diversity limited, Slido provides an avenue for inclusive participation and allows even the most reserved students to contribute anonymously.  Hence, the qualitative study adopted a transformative paradigm as a lens and approached it through active learning designed by Action Research. Furthermore, the study was a two-year project involving third-year business studies students and their transition to, and completion of, their fourth year of study. Seven students were selected as the participants, and data was generated through a Focus Group discussion and analyzed using Thematic Analysis. The study revealed that Slido promotes activeness among students in the module selected in the rural university. In conclusion, Slido offers a promising solution for promoting active learning in rural university classrooms. The study recommends that lecturers should be empowered in terms of resources and training to infuse technology into teaching.

Published: October 2024

The COVID-19 pandemic has severely impacted developing countries, causing educational and economic crises globally. This study explores the necessity of maintaining research in Higher Education (HE) amidst the pandemic's disruptions. It questions whether Higher Education Institutions (HEIs) can sustain research post-COVID-19 while balancing essential functions to avoid risks. Despite extensive studies on HEIs' research sustainability post-pandemic, there is a notable gap in understanding the precise strategies needed to balance essential functions, address risks, and foster resilience amid uncertainties. To bridge this gap, the study highlights the importance of reassessing research priorities and methods in the changing HE landscape. A systematic literature review was conducted, gathering relevant literature from various databases. The study employed an exclusion and inclusion design for research selection. It points out that maintaining HE research post-pandemic has not been sufficiently investigated, leaving a critical gap in understanding research practices. The conceptual model, serving as the study's theoretical foundation, offers an organized means of evaluating the need for HE research considering the pandemic's global economic impacts. This study underscores the importance of multi-stage educational research in the post-COVID-19 era, given the interconnectedness of HEIs. It advocates for a flexible and dynamic research environment and suggests comprehensive approaches to anticipate and meet emerging trends in higher education. The study emphasizes that future research should focus on mitigating post-pandemic challenges and preparing for shifts in HE, promoting resilience and creativity in the field.
Contextualizing Human Rights in Multicultural Environments
Authors: Agyare Patrick
Published: October 2024

This paper explores the intricate relationship between socio-cultural dynamics and human rights in multicultural societies. It examines how norms, belief systems, and power structures shape the perception and exercise of these universal principles. The study employs a qualitative research design, specifically using the Cultural Relativism Framework, to investigate how cultural norms and values influence the interpretation and application of human rights. Through the analysis of literature and case studies, the paper elucidates the interaction between cultural context and human rights interpretations. It acknowledges that human rights are not uniform but are influenced by diverse cultural contexts. Key findings underscore the significance of multiculturalism in human rights interpretation, the impact of social, cultural, and political contexts, the intersection of values, beliefs, and customs, and the roles of states, civil society, and international organizations in shaping human rights discourse. The paper advocates for educational initiatives, intercultural dialogue, inclusive policymaking, and legal reforms to promote and protect human rights in diverse societies. It recommends enhancing human rights education, facilitating intercultural exchange, empowering civil society, addressing discrimination and inequality, and integrating customary laws with formal legal systems. By fostering mutual respect and understanding, societies can uphold human rights and cultural diversity, enabling peaceful, equitable coexistence. This assertion is based on empirical observations and scientific principles that highlight the importance of mutual understanding in preserving human rights and promoting cultural diversity. This paper contributes to a deeper understanding of human rights, advocating for a balance between universal principles and cultural specificities.
Reimagining Learner Engagement Through Flipped Classrooms in the Post COVID-19 Era
Authors: Matiso Nomasomi Hilda
Published: October 2024

The post-COVID-19 era gave rise to the emergence of innovative teaching and learning strategies, which, among others, included flipped classrooms. This article sought to determine whether flipped classrooms are beneficial when online learning material is distributed prior the commencement of the class. Piaget’s (1986) Constructivist Learning Theory underpinned this inquiry. Constructivism is an approach to education that holds that people actively generate their own knowledge and that reality is shaped by the learner's experiences. The interpretive paradigm and a qualitative approach were utilized to collect information through semi-structured interviews with twelve conveniently selected grade 10 teachers. Using a case study design, the researcher could investigate the phenomenon in detail. Findings, which ensued from thematically analysed data, indicated that learners benefit most from pre-class activities as they offer increased participation opportunities as learners engage in discussions in their native languages. Thus, discussions and modelling tasks during in-class activities are learner-centred, with the development of paraphrasing skills, which promote good essay writing skills with minimum plagiarism effects.  The author, therefore, recommends that Teachers require ongoing professional development in applying flipped classrooms using advanced learner-centred technological pedagogies, which promote maximum participation in the learning environment.
