This study explored the efficiencies of Pseudomonas aeruginosa and Bacillus licheniformis isolates in the degradation of a derivative of crude oil, Low Pour Fuel Oil (LPFO), commonly known as Black oil. The comparison was carried out on the effects of nutrient stimulation on the degradation of LPFO by the selected organisms. After a 14-day treatment, correlational analysis of the biodegradation test showed a significant solid correlation between organisms and different treatments at p<0.01. There was an increase in the counts of B. licheniformis and P. aeruginosa during the degradation process. The susceptibility of the hydrocarbon compounds to microbial degradation varied with the type and size of the hydrocarbon molecules. Alkanes of intermediate chain length (C10–C24) were degraded rapidly compared to long-chain alkanes (C20–C34). There was a significant increase in degradation when the LPFO was inoculated with B. licheniformis and P. aeruginosa, while there was no significant effect of nutrient amendment on the hydrocarbon degradation compared to treatments with individual microorganisms alone. The average Degradation Efficiency was 99.9%. Pseudomonas aeruginosa and Bacillus licheniformis isolates were influential in the degradation of LPFO and can be employed in the remediation of contaminated soil.
Keywords: biodegradation, bio-stimulation, biotechnology, hydrocarbon, low-pour fuel oil.

Published: November 2024

Visual processing is crucial for sports performance, influencing athletes' ability to interpret and respond to visual stimuli. This study investigated distinct visual processing patterns among Thai elite athletes in gymnastics, soccer, and esports, utilizing visual P300 event-related potentials (P300 ERPs). Forty-two female athletes (14 gymnasts, 14 soccer players, and 14 esports athletes) participated. Visual P300 ERP responses were stimulated using the visual oddball paradigm. One-way ANOVA was employed to assess significant differences among the groups in P300 ERPs data, including amplitude and latency of waveforms, response time, and accuracy rate. Significant differences were found across the groups in various parameters. Esports athletes exhibited longer P300 ERP latencies at the frontal electrode sites compared to gymnasts (p = 0.01), suggesting slower visual processing in the frontal brain regions. Gymnasts demonstrated the fastest response times, significantly quicker than esports and soccer players (p < 0.01). In contrast, soccer players exhibited the highest accuracy rate (p = 0.03). These findings underscore athletes' diverse visual processing strategies in different sports contexts, reflecting sport-specific adaptations. Understanding these distinct visual processing patterns can guide targeted interventions aimed at improving cognitive abilities and decision-making processes among elite athletes, ultimately contributing to better overall performance.

Authors: Zhu Enxuan
Published: November 2024

In the process of foreign language learning, emotional factor-anxiety, has far-reaching impact on learning results. Anxiety is often regarded as a negative emotional factor in foreign language learning, which may hinder the development of language absorption and application ability. This study investigates the relationship between English classroom anxiety and English achievement among 30 English majors at Nankai University, class of 2022. Utilizing a self-administered questionnaire adapted from the Foreign Language Classroom Anxiety Scale (FLCAS) and analyzing data through correlation and regression analyses, the study reveals a significant negative correlation between students' self-assessed English performance and their levels of anxiety. The findings demonstrate that increased anxiety is predictive of lower English achievement, underscoring the impact of affective factors on language acquisition.

Published: November 2024

Background: Undernutrition among under-five children is a major public health problem in Nepal. The study's main objective was to assess the nutritional status and its associated factors among under-5 children of Bidur Municipality, Nuwakot district using secondary data analysis.
Methods: We analyzed the data of 667 under-five children from 3183 households collected from the Community Health Diagnosis 2023 program database stored in the Kobo toolbox. Nutritional status indicators were measured by using the WHO classification. The chi-square test was applied to find out the association of nutritional status with independent variables such as maternal age at marriage, age at first child, antenatal, delivery, and post-natal care, exclusive breastfeeding, complementary feeding practices, and immunization status.
Results: Nearly 32% (95%CI: 28.3-35.8) of the children were stunted, 12.1% (95%CI: 9.7-14.7) wasted, and 13.9% (95%CI: 11.4-16.6) were underweight. Early age at marriage, less than four ANC visits by the mother, history of substance use during pregnancy, and not exclusively breastfeeding were significantly associated with different forms of undernutrition.
Conclusion: Promotion of exclusive breastfeeding and a higher number of ANC visits and discouraging early-age marriage and substance use during pregnancy are necessary to prevent undernutrition in under-five children.

Black-Letter Methodology in Public Health Research
Authors: Aryal Arjun
Published: November 2024

In comparison to other public health disciplines, such as epidemiology and social sciences, the significance of law in promoting population-level health advances is relatively underutilized and less well-studied. Black-letter methodology, also known as doctrinal research, traditionally used in legal studies, focuses on the systematic analysis of legal texts and statutes. Black-letter methodology indicates the fundamental components of legal study that are not subject to dispute or uncertainty. It is generally recognized by the majority of justices in a specific jurisdiction. The fundamental sources of law, such as legislation, are the focus of the black-letter analysis. In public health, the objective of black-letter methodology is to acquire an understanding of the ways in which the legal determinants, including various laws, procedures, systems, and provisions, affect the health of the people involved. This methodology can be adapted to public health research to examine the impact of laws and regulations on health outcomes. This viewpoint explores the application of the black-letter methodology in public health, highlighting its potential to provide robust insights into the legal determinants of health.

Published: November 2024

Background: Job satisfaction is a vital concern for both managers and academics. Biomedical Equipment Technicians (BMETs) exemplify technical professionals and have also been affected by the factors of job satisfaction. This research is mainly focused on the job satisfaction of BMETs working in government and private health facilities to determine the factors affecting job satisfaction in their present scenario.
Methods: We distributed questionnaires to all 148 Biomedical Equipment Technicians (BMETs) in Nepal, with 91 of them responding. Additionally, we gathered qualitative data from 6 BMETs from 6 health facilities, evenly split between urban and non-urban regions, with 3 facilities from each type. 18 interviews (FGD with the department in charges, interview with the Medical Superintendent and an interview BMET of each facility) were also conducted across these 6 health facilities. Our analysis included a descriptive examination of the survey data and a comparison of job satisfaction factors between the government and private sectors. Furthermore, we utilized NVivo 12 to code the qualitative data based on themes.
Results: The data shows that there is no significant difference between Biomedical Equipment Technicians (BMETs) in the government and private sectors overall. However, it does reveal that BMETs in government hospitals tend to be more satisfied with their earnings compared to those in the private sector. While the overall levels of satisfaction and dissatisfaction are similar for both groups of participants, some of the specific levels of satisfaction and dissatisfaction differ between them.
Conclusion: Overall, BMETs find enjoyment in their work, showcasing their dedication to their roles despite the various unsatisfactory factors present in hospital settings in both government and private sectors.

Background:
Elder abuse is a growing public health problem. To tackle the elder issues World Health Organization, declare for the decade of healthy ageing from 2020 to 2030, where Nepal is not exception from this goal. Thus, the study aims to assess the prevalence of abuse and its associated factors among elder population living in Kawasoti Municipality. Methods: A community based cross sectional study was conducted, taking 422 elders who were 60 years and above. The face-to-face interviews were conducted from October 2018 to January 2019. The collected data were entered into EpiData 3.1 and was exported to SPSS 26 version. The logistic regression was performed to measure associated between overall abuse and its covariates.
 
Results:
The overall prevalence of elder abuse was 43.8% and caregiver neglect was the most reported form of elder abuse. Study found that nuclear family [OR=0.42, 95% CI;0.18-0.97], illiterate [OR: 2.01, 95% CI; 1.11-3.96], family members have no migrated to another country [OR=0.57, 95% CI; 0.33-0.97], health condition was bad [OR= 1.92, 95% CI; 1.15-3.21], elder who did not depend on their daily activities on family members [OR=0.25, 95% CI; 0.12-0.52], and those who had consumed tobacco [OR= 1.91, CI; 1.19-3.06] were associated with elder abuse.
 
Conclusion:
The finding suggests that good health, a nuclear family, literacy, family members not migrated to another country, and independence in daily activities strongly reduce elder abuse. To address this, it is essential to implement awareness programs, and ageing population for their economic sustainability activities, and healthy and active aging life.
Prevalence and Determinants of Exclusive Breastfeeding among Working Mothers of Infants Aged 6 to 12 months: A Hospital-Based Cross-Sectional Study in Kathmandu, Nepal
Authors: Basnet Rojina , Karki Rajesh , Poudel Roshani
Published: November 2024

Background: Exclusive breastfeeding, a vital infant feeding practice, may be influenced by workplace factors and women’s labor force participation. This study aims to identify the prevalence of exclusive breastfeeding practices and associated factors among working mothers with infants aged 6 to 12 months.
Methods: A hospital-based cross-sectional study took place from February 2016 to April 2016, involving 250 working mothers at Kanti Children’s Hospital, Kathmandu. Mothers were purposively selected and underwent face-to-face interviews using a structured questionnaire. Descriptive statistics, including frequencies, percentages, mean, median, and standard deviation, presented study findings. Multivariate logistic regression analysis identified significant factors associated with exclusive feeding (p < 0.05).
Results: In the total sample, the majority of mothers (49.0%) were aged 30-35 years, with a mean age of 29.93 (± 2.79) years. Approximately one-third (33.0%) practiced exclusive breastfeeding, and the majority (52.0%) were employed in academic sectors. While all mothers had access to maternity leave, only 1.6% took a 6-month leave. More than half of the mothers (56%) exhibited poor knowledge of exclusive breastfeeding, and 76% expressed a positive attitude towards workplace breastfeeding. Factors associated with increased exclusive breastfeeding included good knowledge, longer maternity leave, a complete history of postnatal checkups, and the availability of breastfeeding facilities in the workplace.
Conclusion: Our data indicate a low prevalence of exclusive breastfeeding among working mothers. We recommend the effective implementation of government policies regarding maternity leave and breastfeeding facilities in the workplace. This includes advocating for exclusive breastfeeding, ensuring that both public and private organizations comply with maternity leave provisions, providing adequate breastfeeding facilities at workplaces, and enhancing awareness about the importance of exclusive breastfeeding for the health of both mother and child.

Authors: Khan Saba , Zareef Uzma , Chughtai Nadia , Imtiaz Syed Ashar , Askary S Hussain , Askary Gul Rukh
Published: November 2024

Oral cancer is a life-threatening disease that predominantly affects the oral cavity, with approximately 90% of cases being oral squamous cell carcinomas (OSCC). Rapid metastasis and late detection are key factors contributing to the poor prognosis of OSCC. The alarming rise in OSCC-related mortality underscores the urgent need for clinical diagnostic methods that enable early detection. In recent years, salivaomics has gained popularity in molecular diagnostics due to the accessibility and non-invasive nature of saliva. Researchers have identified over 100 salivary biomarkers with potential roles in OSCC screening, categorized into proteomic, genomic, transcriptomic, and metabolic biomarkers. Although these biomarkers show high specificity and sensitivity, challenges such as variability and the need for standardized protocols must be addressed to improve diagnostic accuracy and treatment outcomes. This review explores significant salivary biomarkers in OSCC management and highlights the challenges that hinder their clinical application, emphasizing the need for optimized protocols to enhance test validity

Published: November 2024

The risks posed by Artificial Intelligence (AI) are of considerable concern to academics, auditors, policymakers, AI companies, and the public. However, a lack of shared understanding of AI risks can impede our ability to comprehensively discuss, research, and react to them. This paper addresses this gap by creating an AI Risk Repository to serve as a common frame of reference. This comprises a living database of 777 risks extracted from 43 taxonomies, which can be filtered based on two overarching taxonomies and easily accessed, modified, and updated via our website and online spreadsheets. We construct our Repository with a systematic review of taxonomies and other structured classifications of AI risk followed by an expert consultation. We develop our taxonomies of AI risk using a best-fit framework synthesis. Our high-level Causal Taxonomy of AI Risks classifies each risk by its causal factors (1) Entity: Human, AI; (2) Intentionality: Intentional, Unintentional; and (3) Timing: Pre-deployment; Post-deployment. Our mid-level Domain Taxonomy of AI Risks classifies risks into seven AI risk domains: (1) Discrimination & toxicity, (2) Privacy & security, (3) Misinformation, (4) Malicious actors & misuse, (5) Human-computer interaction, (6) Socioeconomic & environmental, and (7) AI system safety, failures, & limitations. These are further divided into 23 subdomains. The AI Risk Repository is, to our knowledge, the first attempt to rigorously curate, analyze, and extract AI risk frameworks into a publicly accessible, comprehensive, extensible, and categorized risk database. This creates a foundation for a more coordinated, coherent, and complete approach to defining, auditing, and managing the risks posed by AI systems.
Teachers’ perspectives of factors affecting lesson planning practices in Vanuatu mathematics classrooms
Authors: Mwaraksurmes Amton Serel
Published: November 2024

Sustainable education is becoming a hot topic in debates and discussions worldwide. There are concerns that current education systems are not providing for the needs of all people in a sustainable way. Many countries are taking steps to ensure a type of education that will sustain their citizens and meet the challenges of tomorrow. In Vanuatu, such attempts are made through official documents such as the National Curriculum Statement (NCS), a policy statement to improve teaching, learning and teacher education. The NCS states that good teaching requires carefully planned strategies. This study investigated Vanuatu’s secondary school teachers’ perspectives on the factors that affect their lesson-planning strategies for
achieving student-centred learning. Twenty secondary school mathematics teachers in Port Vila participated in this 2022 study. First, mathematics lesson plans were collected and analysed to evaluate whether the teachers could plan student-centred learning. Second, the teachers were interviewed individually to gauge their views on factors hindering their attempts to design student-centred learning. Data collected was analysed using a thematic analytical tool. The findings revealed the need to support teachers in lesson planning, particularly designing and using student-centred learning strategies.
Motivational factors influencing students’ learning: A Samoan case study
Authors: Tufue Rasela , So’otaga Grace Honiara
Published: November 2024

When students leave the schooling systems prematurely, a common question is: How can students be motivated to remain and be successful in their educational journeys? The qualitative research discussed in this article examined the factors motivating students in a Samoan context. Fifteen primary school students were interviewed about the factors influencing their learning. The findings did not reveal intrinsic motivation as a significant drive for student participants. On the contrary, extrinsic factors (e.g., family expectations and positive learning environments) took precedence over internal motivations. This finding suggests that other factors, such as students’ culture, may significantly influence students’ motivation. Future research could further explore whether or how intrinsic factors may influence students’ academic success within a Samoan context.
The epidemic of academic dishonesty in open and distance e-learning: a case study of a regional campus at Zimbabwe Open University
Authors: Kurebwa Mercy , Lumbe Abigirl
Published: November 2024

The objective of the study is to examine the occurrence of cheating in Open and Distance e-Learning (ODeL), specifically during examinations and assignment writing. To obtain a comprehensive understanding of individuals´ views on cheating in ODeL, a qualitative naturalistic research design was utilized. Participants for the study were selected using judgmental sampling technique and included twenty, (20) students, ten (10) lecturers and two (2) administrative staff at the Midlands Regional Campus. In-depth interviews were conducted with the chosen participants until saturation point was reached, enabling the researchers to gather detailed and insightful information. After data generation, thematic analysis was employed to identify recurring patterns and themes within the responses. Data were systematically organized and interpreted to uncover key ideas, concepts, and viewpoints related to cheating in ODeL. The study was informed by the Attribution Theory, which offers a framework for understanding the underlying reasons and motivations behind cheating behaviour. By employing this theory, the study gained insights on the factors influencing cheating behaviour in the context of ODeL. The study revealed a concerning prevalence of cheating in ODeL with a high occurrence of cheating in assignments. The study proposes a comprehensive approach to fostering academic integrity and reducing cheating in the ODeL programs at Midlands Regional Campus. Key recommendations include enforcing rigorous identity verification and severe penalties for cheating to deter misconduct, establishing comprehensive policies with regular monitoring, and cultivating a culture of academic honesty through workshops and student engagement. The study also suggests providing resources and affordable data access for marginalized students, as well as implementing and maintaining electronic security systems and proctoring tools to prevent cheating. By implementing this multifaceted approach, the study aims to uphold academic integrity, support student success, and significantly reduce cases of cheating in the ODeL programs.
Manipulatives: mediators of mathematics development for foundation phase learners
Authors: Sikhwari Matodzi G , Feza Nosisi N
Published: November 2024

This paper explores the effectiveness of using physical objects, or manipulatives, in teaching mathematics to Foundation Phase learners aged to 8 in the Eastern Cape Province of South Africa. The study is grounded in Piaget's Theory of Cognitive Development and uses a qualitative research design. Ten videos were selected, and clinical interviews were conducted with each learner individually while they used manipulatives. The data was analyzed thematically. The study found that manipulatives are an inexpensive and effective resource for teaching mathematics, as they enable children to understand key concepts through hands-on experience, and later connect these ideas to abstract concepts. Based on these findings, the study recommends that teachers and learners incorporate manipulatives in all units of the mathematics curriculum for effective teaching and learning in lower grades.

Paleocene Ostracoda from Nûgssauq, West Greenland.
Authors: Szczechura Janina
Published: November 2024

This paper is the first description of post-Palaeozoic ostracods from Greenland. The material was collected from the Paleocene (Danian) Agatdal Formation on Nugssuaq, West Greenland, a formation which has yielded a huge fauna -over 600 species, mostly gastropods and pelecypods. The ostracod assemblage described comprises 96 specimens belonging to 39 species of 24 genera belonging to the suborders Cladocopina, Platycopina and Podocopina. The genera represented have very varied age ranges; some are known from Paleocene to Recent, others range from Jurassic or Cretaceous up to Recent time. One genus, Sclerochilus, has not previously been found in deposits earlier than Miocene, while another, Orthonotacythere, ranges from Jurassic to Paleocene. None of the species could be assigned with certainty to any hitherto described species and therefore the assemblage is considered to be endemic and consequently does not throw new light on the age of the Agatdal Formation. In the case of four species the material is sufficiently well preserved and plentiful to allow the description of the new species Bairdia agatdalensis, Cushmaniden, rosenkrantzi, Hazelina nova and Loxoconcha groenlandica.
The Vegetational Relations of Weathering, Frost Action, and Patterned Ground Processes, in the Mesters Vig District, Northeast Greenland.
Authors: Raup Hugh M.
Published: November 2024

Botanical descriptions and analyses presented in this paper apply to representative sites selected from those discussed by WASHBURN in "Weathering, frost action, and patterned ground in the Mesters Vig district, Northeast Greenland" (Meddr Grønland 1969, Bd. 176 No. 4). They deal with vegetation-site relations in the following habitat complexes: rocky hilltops, ledges, crevices and talus; simple and compound nonsorted circles and their included small nonsorted polygons; small sorted and nonsorted polygons on emerged delta remnants; large nonsorted polygons; debris islands; and large sorted nets. Site factors used are: coverage of the ground by vascular plants; moisture supply; and physical disturbance of the soil by frost - and nonfrost-induced geomorphic processes. The vegetations are analyzed with respect to their species' tolerance of variation and intensity in the factor gradients.A summary compares the sites in terms of the relative proportions of wide, intermediate and narrow tolerance shown by their vascular floras on each of the gradients. The analyses presented show, as did those made for the mass-wasting sites,positive correlations between the local distribution of species tolerance and the local behavior of the site factors of coverage, moisture and physical disturbance. They suggest further that the ratings of species tolerance made from general observations are sufficiently valid to be useful as indicators of these site conditions.

Silurian Stratigraphic Sections at Kap Tyson, Ofley Ø and Kap Schuchert, Northwestern Greenland.
Authors: Norford B. S.
Published: November 2024

The Silurian formations of northwestern Greenland are an intricate assemblage of graptolitic rocks and limestones of varied facies deposited at the seaward edge of a carbonate platform that probably covered most of extreme northern Greenland during Silurian time. Facies changes are abrupt and the formations are in part facies equivalents of each other. The Offley Island Formation consists of biostromal and biohermal limestones and associated calcarenites and limestone conglomerates. The cores of the biostromes and bioherms are primarily formed by stromatoporoids, algae and colonial corals. The Cape Schuchert Formation predominantly is composed of slightly argillaceous calcisiltites but includes minor biostromal and biohermal limestones andrelated calcarenites. The graptolitic rocks are assigned to the Cape Phillips Formation and consist of calcareous shales and mudstones, cherts, argillaceous limestones and locally developed small bioherms. The term Cape Tyson Formation is consideredobsolete. All the rocks exposed at the studied localities are about Late Llandovery in age but younger and older Silurian rocks may be present elsewhere in northern Greenland. Small amounts of lead and zinc mineralisation are present within the Cape Schuchert Formation at Kap Schuchert. Petroleum residues are preserved within a prominent bioherm within the Offley Island Formation at Kap Tyson. The bioherm is about 1,100 feet (350 metres) thick and has a relief of about 800 feet (250 metres) . Extensive development of biostromal and biohermal rocks may be characteristic of the seaward edge of the Silurian carbonate platform in Greenland and the Canadian Arctic Islands. The position of the edge can be traced from Greenland to east-central Ellesmere Island and probably runs southwestward through Ellesmere Island and Grinnell Peninsula to Cornwallis Island, from there westward south of Bathurst Island and Melville Island.

The Fiskenæsset complex, which occurs as conformable layers up to 1.5 km thick in high grade Early Archaean gneisses, has a well-preserved igneous stratigraphy. An upward sequence of lithological zones is observed in the complex as follows: 1. Pyroxene Amphibolite; 2. Ultramafic Group (hornblende-bearing spinel- and magnetite-layered dunites, peridotites, pyroxenites); 3. Layered leuco-gabbro; 4. Dark gabbro; 5. Homogeneous leuco-gabbro; 6. Anorthosite; 7. Chromite horizon; 8. Garnet Anorthosite; 9. Pyroxene Amphibolite. Eighteen whole rock XRF analyses (for major and trace elements) indicate that this sequence is mainly the differentiation product of a basaltic magma. Cryptic layering is present within zones 2 to 8 inclusive, and shows that this part of the sequence belongs to a stratiform igneous intrusion, zone 8 being the topmost layer of the original igneous stratigraphy. There is especially a marked upward increase in the Fe/Mg ratio. The amphibolites of zones 1 and 9 are much richer in iron than any rocks belonging to the intrusion, and are considered to have been volcanics into which it was emplaced. Metasomatic sapphirine-rich rocks are localised along the contact of zones 8 and 9. The complex has internal sub-complexes within which its upper zones are locally confined. The stratigraphic sequence is repeated symmetrically in reverse order and the differentiation trends of the two halves mirror each other. The original body was flattened so that its layering was deformed into an isoclinal syncline. This deformation accounts for the repeated stratigraphy. The complex was subsequently double folded and metamorphosed under both granulite and amphibolite facies conditions. Mineral assemblages indicate that there may have been appreciable water in the original magma, and this viewpoint is strengthened by the observed differentiation trend.
Tertiary peralkaline rhyolite dikes from the Skærgaard area, Kangerdlugssuaq, East Greenland.

Published: November 2024

Tertiary peralkaline acid rocks (comendites) are described from East Greenland. These are dike rocks, which may be aphyric, carry sparse phenocrysts of alkali feldspar, or more abundant quartz, alkali feldspar and katophorite phenocrysts. Regarded as being closely related, are a group of peralkaline granitic rocks associated with the nordmarkitic syenites of the area, which contain quartz, alkali feldspars, arfvedsonite, pyroxenes ranging from hedenbergitic to acmitic, and assessories including zircon, Mn-rich ilmenite, astrophyllite and chevkinite. Analyses are presented for most of these phases and the chemistry of the rocks and that of the crystallization process in the dike centres is discussed. These rocks have an origin clearly distinct from that of the nearby Skaergaard granophyres, which show no peralkaline tendencies, and it is postulated that the comendites have arisen from magmas of nordmarkitic composition which, in turn, arose at depth from a transitional basalt. This suite of rocks seems to reflect closely the tectonic setting, occurring in many areas of crustal attenuation, a situation in accordance with that believed to be present here.

A Process and Impact Evaluation of a University’s Module Evaluation Questionnaire (MEQ)
Authors: Donnelly Alan , Heaton Caroline
Published: November 2024

In 2020/21, a review was commissioned by Sheffield Hallam University’s Leadership Team into the Module Evaluation Questionnaire (MEQ) to find out what difference it was making and how the data was being used. A range of evidence was gathered and drawn upon for this mixed-methods evaluation, including: online focus groups and interviews with 60 module leaders across three colleges; an online reflective activity with teaching and learning (T&L) portfolio leads from 10 departments; interviews with 19 student course representatives; monitoring data and other evidence; and findings from literature and research across the sector. The steady fall in response rates in recent years, not just when the delivery of MEQs changed from paper to online, had limited the use of the data and its ability to fulfil its intended purposes in relation to quality assurance and quality enhancement. The standardised design of the MEQ was seen as a factor that restricted its potential usefulness, with many module leaders and some T&L portfolio leads and, to a lesser extent, students stating that the MEQ should be more reflective of the complexity of their modules. Relevant literature highlighted a range of factors that are helpful in promoting questionnaires to students, but the findings of this evaluation suggested that there was a limit to how much effect these practices had. Some practices were perceived to be harder to implement when teaching and learning was delivered predominantly in an online environment. According to module leaders, the switch to online delivery of MEQs a few years before made it harder to personalise and explain their purpose and value to students. Some student reps were motivated to take part in the MEQ process, but others were reluctant to engage. There is a need to strengthen evaluation capacity building at all levels, of which a key component is to provide more guidance about interpreting and analysing students’ responses, particularly when response rates are low. Recommendations are provided to address specific issues identified from the evaluation findings.
Implementation preventive program for diabetic mellitus (PROLANIS) at Community Health Center in Indonesia: A qualitative study

Published: November 2024

Chronic diseases pose a significant challenge for elderly communities, with diabetes mellitus demanding particular attention. To address this, Indonesia’s Universal Health Coverage Program, commonly known as BPJS (Badan Penyelenggara Jaminan Sosial), established PROLANIS (Program untuk Lansia dan Penyakit Kronis). This program caters specifically to the elderly, offering comprehensive support through medical consultations, group education sessions, physical activities, SMS reminders, home visits, and regular health monitoring. However, PROLANIS implementation varies across regions. Geographical factors, access to facilities, stakeholder perspectives, and healthcare worker input all influence how the program is delivered. This research aims to identify the implementation of PROLANIS activities in five diverse regions in Indonesia. Utilizing a qualitative approach, the research employs in-depth interviews as its primary data collection method. The Consolidated Framework for Implementation Research (CFIR) guides the study, focusing on both intervention characteristics and the implementation process itself. PROLANIS services are integrated within existing healthcare structures at the village/sub-district level, seamlessly blending with other services available to the elderly population. Planning and execution of general activities adhere to national operational standards, ensuring consistency across regions. Physical exercise sessions, for instance, occur routinely, at least every 2 weeks or once a month. Recognizing regional differences, the program allows for special adaptations to overcome challenges. These adaptations, often influenced by human resource limitations, local infrastructure, and logistical hurdles such as transportation or scheduling constraints, ensure program effectiveness despite varying contexts.
Layer 6 corticocortical cells dominate the anatomical organization of intra and interhemispheric feedback
Authors: Weiler Simon , Teichert Manuel , Margrie Troy W

The mouse neocortex contains at least ninety functionally distinct areas that are symmetrically located across the two hemispheres. Determining the logic of this long range circuitry is necessary for understanding how inter-areal cortical integration enables high level brain function involving multiple sensory, motor and cognitive processes. To address this we have performed a systematic anatomical analysis of the areal and laminar organization of the ipsilateral and contralateral cortical projection onto the primary visual (VISp), primary somatosensory barrel field (SSp-bfd) and primary motor (MOp) cortices. The resultant input maps reveal that although the ipsilateral hemisphere is the major source of cortical input, there is substantial bilateral symmetry regarding the relative contribution and areal identity of cortical input. Laminar analysis of these input areas show that intra and interhemispheric connectivity is mediated predominantly by excitatory Layer 6 corticocortical cells (L6 CCs). Based on cortical hierarchy analysis that compares the relative contribution of inputs from supra- (feedforward) and infra-granular (feedback) layers, we find that contra-hemispheric projections reflect a dominant feedback organization compared to their ipsi-cortical counterpart, independent of the target injection area. The magnitude of the interhemispheric difference in hierarchy was largest for sensory and motor areas compared to frontal, medial or lateral brain areas and can be explained by a proportional increase in input from L6 projection neurons. L6 CCs therefore not only dominate corticocortical communication but also reflect its inherent feedback organization.
