Quasi-thermal Noise Spectroscopy Analysis of Parker Solar Probe Data: Improved Electron Density Model for Solar Wind
Authors: Kruparova Oksana , Krupar Vratislav , Szabo Adam , Pulupa Marc , Bale Stuart D.
Published: October 2023

We present a comprehensive analysis of electron density measurements in the solar wind using quasi-thermal noise (QTN) spectroscopy applied to data from the first 15 encounters of the Parker Solar Probe mission (2018 November–2023 March). Our methodology involves the identification of the plasma line frequency and the calculation of plasma density based on in situ measurements. By analyzing over 2.1 million data points, we derive a power-law model for electron density as a function of radial distance from the Sun in the range of 13 to 50 R
☉: n
e(r) = (343,466 ± 19921) × r
(−1.87±0.11). This model provides improved estimates for localizing interplanetary solar radio bursts. Moreover, obtained electron densities can be used for calibrating particle instruments on board the Parker Solar Probe. We discuss its limitations and potential for further refinement with additional Parker Solar Probe encounters.
A Gigantic Mid-infrared Outburst in an Embedded Class I Young Stellar Object J064722.95+031644.6
Authors: Wang Tinggui , Li Jiaxun , Mace Gregory N. , Ji Tuo , Jiang Ning , Zhu Qingfeng , Fang Min
Published: October 2023

We report the serendipitous discovery of a giant mid-infrared outburst from a previously unknown source near a star-forming region in the constellation Monoceros. The source gradually brightened by a factor of 5 from 2014–2016 before an abrupt rise by a factor of more than 100 in 2017. A total amplitude increase of >500 at 4.5 μm has since faded by a factor of about 10. Prior to the outburst, it was only detected at wavelengths longer than 1.8 μm in UKIDSS, Spitzer, and Herschel with a spectral energy distribution of a Class I young stellar object (YSO). It has not been detected in recent optical surveys, suggesting that it is deeply embedded. With a minimum distance of 3.5 kpc, the source has a bolometric luminosity of at least 9 L
☉ in the quiescent state and 400 L
☉ at the peak of the eruption. The maximum accretion rate is estimated to be at least a few 10−5
M
☉ yr−1. It shares several common properties with another eruptive event, WISE J142238.82-611553.7: exceptionally large amplitude, featureless near-infrared spectrum with the exception of H2 lines, intermediate eruption duration, an embedded Class I YSO, and a low radiative temperature (<600–700 K) in outburst. We interpret that the radiation from the inner accretion disk and young star is obscured and reprocessed by either an inflated outer disk or thick dusty outflow on scales >6.5 au during the outburst.
The diversity of macromycetes in peatlands: nine years of plot-based monitoring and barcoding in the raised bog "Mukhrino", West Siberia

Published: October 2023

Peatland ecosystems are defined by soils with sufficient under-decomposed organic layer, called peat, formed under anoxic conditions. Peatlands are widespread around the world, with several highly paludified regions, one of which is the Western Siberian Plain. Peatlands store large amounts of carbon and are important in their intact state to counteract climate change, as well as for a variety of other ecosystem functions. From the practical aspect, these ecosystems are used as a source of peat for fuel, peat-based fertilisers and growing media, berries and Sphagnum plantations. Fungi are the key part of the decomposer community of peatlands, playing a critical role in the aerobic decomposition in the upper peat layer. The community of peatland fungi is adapted to decomposition of peat and dead parts of Sphagnum in wet acidic conditions; they form specific mycorrhizal associations with a variety of plants. Thus, the research of fungal diversity of peatlands is important for several reasons: 1) adding knowledge of peatland fungal diversity to local or global biodiversity databases; 2) studying carbon cycling in peatlands; 3) using peat and peatlands for different applications, such as cultivation of Sphagnum with regards to some parasitic species of fungi and 4) peatland restoration and conservation, to mention a few.

The community of macromycetes of the raised bog “Mukhrino” in Western Siberia was studied using plot-based monitoring throughout a 9-year observation period. The revealed species diversity is represented by approximately 500 specimens in the Fungarium of Yugra State University collection. Selected specimens were used for barcoding of the ITS region to reveal a total of 95 species from 33 genera and three classes. The barcoding effort confirmed morphological identifications for most specimens and identified a number of cryptic species and several potentially new taxa. Based on regular all-season observations, we describe the phenology of the community sporophore production. The quantitative community structure, based on sporophores, revealed a difference in abundance between species by four orders of magnitude, with rare species representing nearly half of the species list. The inter-annual fruiting abundance varied several times by the total number of sporophores per year. To make the comparisons with global studies, we created an open access database of literature-based observations of fungi in peatlands, based on about 120 published papers (comprising about 1300 species) and compared our species list with this database.

As a result, the study created an accurate representation of taxonomic and quantitative structure of the community of macromycetes in raised bogs in the region. The raw data of plot-based counts was published as a sampling-event dataset and the sequenced specimens with the sequence information as an DNA-derived extension dataset in GBIF.

Reimagining the Food System: Kropotkin, Food Sovereignty and OrganicLea
Authors: Pewton Tomas
Published: October 2023

This paper explores the similarities between Kropotkin's vision of a just food system and the food sovereignty movement, with the concrete example of the work of OrganicLea. It will begin with an analysis of the deepening problems of our food system through food insecurity and its negative
impact upon the environment. The second part will introduce the idea of food sovereignty and show how it intersects with Kropotkin's work, with it being argued that a just food system is one that recognises central aspects of both; alongside local and collective ownership, the well-being of
all, regenerative agriculture and a commitment to wider social and environmental justice. I will then show how such principles are being put into practice through the work and direct action of OrganicLea. This will reveal how Kropotkin's thought is still relevant today and how it can be used
to address contemporary concerns such as food insecurity and climate change. The paper will also consider the limitations of Kropotkin, including his time-restricted ideas, and the need for new perspectives such as those found in OrganicLea and the food sovereignty movement.
Recherches sur programmes : enjeux scientifiques intra- et interdisciplinaires en géographie de l’environnement
Authors: Cossart Étienne
Published: October 2023

Une conséquence déjà bien documentée de la recherche sur programmes est celle de la prise en compte accrue des « intérêts de la société » dans les questions de recherche (Gibbons et al. , 1994 ; Hubert et al. , 2011). Dans le champ thématique de l’environnement, cette conséquence revêt la forme d’une injonction au développement de stratégies de remédiation, dans le contexte des changements environnementaux contemporains et à venir. Pour y parvenir malgré la complexité des questions environnementales, l’interdisciplinarité est largement promue (Leblanc et al. , 2019) et constitue souvent un critère d’éligibilité explicite dans les appels à projets. Sur la base d’un corpus de programmes, nous identifions les relations scientifiques interdisciplinaires qui mobilisent la géographie. Une typologie en trois principales catégories est proposée et nous présentons les objectifs qu’elles visent. Toutefois, nous montrons également que cette injonction à l’interdisciplinarité peut entraver les collaborations intradisciplinaires entre ( i ) les géographes qui peuvent être tourné.e.s vers les « humanités environnementales », dont les pratiques mobilisent les cadres et méthodes des sciences sociales, et ( ii ) celles et ceux tourné.e.s vers les « géosciences », dont les pratiques s’inscrivent dans les sciences expérimentales. Chaque champ intradisciplinaire à la géographie peut ainsi être renvoyé à ses propres cadres de pensées habituels, pouvant ralentir les efforts mis en œuvre pour réunir l’ensemble de la communauté des géographes travaillant sur les questions environnementales.

Cet article passe en revue l’état de l’art du traitement cognitif de la liaison française dans les domaines de la production et de la perception. Les études de corpus au cours des dernières décennies ont montré l’extrême variabilité du phénomène ; les données psycholinguistiques ont révélé que les locuteurs compensent le défaut d'alignement entre signal et entrée lexicale grâce aux informations ascendantes dites encore « de bas en haut » ou bottom-up (acoustiques, phonotactiques) et descendantes dites encore « de haut en bas » ou top-down (contexte phrastique). Nous esquissons un plan de recherche future en neuro-cognition qui viserait à comprendre la façon dont les locuteurs traitent différents types de liaisons en contexte.
A faster iterative scheme for solving nonlinear fractional differential equations of the Caputo type
Authors: Okeke Godwin Amechi , Udo Akanimo Victor , Alqahtani Rubayyi T. , Alharthi Nadiyah Hussain
Published: October 2023

In this paper, we introduce a new fixed point iterative scheme called the AG iterative scheme that is used to approximate the fixed point of a contraction mapping in a uniformly convex Banach space. The iterative scheme is used to prove some convergence result. The stability of the new scheme is shown. Furthermore, weak convergence of Suzuki's generalized non-expansive mapping satisfying condition (C) is shown. The rate of convergence result is proved and it is demonstrated via an illustrative example which shows that our iterative scheme converges faster than the Picard, Mann, Noor, Picard-Mann, M and Thakur iterative schemes. Data dependence results for the iterative scheme are shown. Finally, our result is used to approximate the solution of a nonlinear fractional differential equation of Caputo type.
Approximating fixed points of demicontractive mappings in metric spaces by geodesic averaged perturbation techniques
Authors: Salisu Sani , Berinde Vasile , Sriwongsa Songpon , Kumam Poom
Published: October 2023

In this article, we introduce the fundamentals of the theory of demicontractive mappings in metric spaces and expose the key concepts and tools for building a constructive approach to approximating the fixed points of demicontractive mappings in this setting. By using an appropriate geodesic averaged perturbation technique, we obtained strong convergence and $ \Delta $-convergence theorems for a Krasnoselskij-Mann type iterative algorithm to approximate the fixed points of quasi-nonexpansive mappings within the framework of CAT(0) spaces. The main results obtained in this nonlinear setting are natural extensions of the classical results from linear settings (Hilbert and Banach spaces) for both quasi-nonexpansive mappings and demicontractive mappings. We applied our results to solving an equilibrium problem in CAT(0) spaces and showed how we can approximate the equilibrium points by using our fixed point results. In this context we also provided a numerical example in the case of a demicontractive mapping that is not a quasi-nonexpansive mapping and highlighted the convergence pattern of the algorithm in Table 1. It is important to note that the numerical example is set in non-Hilbert CAT(0) spaces.
Conservation laws and symmetry analysis of a generalized Drinfeld-Sokolov system
Authors: Garrido Tamara M. , de la Rosa Rafael , Recio Elena , Márquez Almudena P.
Published: October 2023

The generalized Drinfeld-Sokolov system is a widely-used model that describes wave phenomena in various contexts. Many properties of this system, such as Hamiltonian formulations and integrability, have been extensively studied and exact solutions have been derived for specific cases. In this paper we applied the direct method of multipliers to obtain all low-order local conservation laws of the system. These conservation laws correspond to physical quantities that remain constant over time, such as energy and momentum, and we provided a physical interpretation for each of them. Additionally, we investigated the Lie point symmetries and first-order symmetries of the system. Through the point symmetries and constructing the optimal systems of one-dimensional subalgebras, we were able to reduce the system of partial differential equations to ordinary differential systems and obtain new solutions for the system.

Replicas, Revivals and Restorations: a Scottish Political Miscellany
Authors: MacKechnie Aonghus
Published: October 2023

Architectural revivalism is generally associated with both the revival of classical models as a common inheritance and, afterwards, with Romanticism and its accompanying national movements such as the Gothic Revival. Scottish architectural revivalism is usually characterised by the 19th-early 20th centuries (neo-castellated) Scotch Baronial style which replicated specific architectural features of historic buildings. This article broadens that scope of analysis by considering revivalism and the choice use of replicates within Scotland across the centuries. Replicates existed c.700CE on Iona island, while revivalism was deployed repeatedly: Iona’s “Celtic” High Crosses were reproduced (in variant form) in the 14th-15th centuries within Gaeldom, and once again during the 19th-20th centuries Celtic Revival. By referencing bygone periods of strength and influence, revivalists adumbrated a political message of greatness, embracing cultural and national identities. In Scotland, stateless from the 18th century, revivalists also expressed conflicted or dual identities. Additionally, when Scotland’s historical resources were considered unsuitable, other models were imported. The European Counter-Reformation church of the Gesù was used a model for James VII & II’s Canongate Kirk (1688); whereas the Tudor Gothic style was imported from England during the Napoleonic period of high British nationalism, evoking and celebrating a British past that never existed.
Nemo me impune lacessit or Ne obliviscaris? The Highlander Soldier in British Parliamentary Debates (18th-21st centuries)
Authors: Coudray Pierre-Louis
Published: October 2023

In the past two decades, Scotland’s military identity has been the subject of several historical analyses, placing it in relation to the decline of Britain as an imperial power and as a nation.1 Few studies, however, have offered an overview of the treatment of the Highlander soldier in parliamentary debates since the eighteenth century. This article draws on Cobbett’s Parliamentary History of England,2 official transcripts of parliamentary debates provided by British History Online3 and Hansard4, as well as on press articles, in order to demonstrate that the Highlander soldier, whose uniform is instantly recognisable, was seen either as a threat to, or as a symbol of, British power and that he fitted in wider discussions on defence and Scottish identity.
The Scottish Independence Movement: National or Nationalist?
Authors: Duclos Nathalie
Published: October 2023

Focusing on the case of the Scottish independence movement, this article aims to reflect on whether support for independence necessarily equates to nationalism. The reflection hinges on two premises: first, independence does not hold the same importance for all pro-independence actors, and second, many of them have chosen to put a rejection of nationalism at the heart of their case for independence. The article argues in favour of dividing pro-independence actors into two groups: nationalists for whom the pursuit of self-government is not only a means to other ends, but also an end goal to be achieved on the basis of nationalist principles; and non-nationalists for whom independence is only ever presented as a means to other, greater ends. The article suggests that rather than a nationalist movement, the Scottish independence movement is perhaps best described as a “national” movement, i.e. a Scottish-wide coalition of actors united in their support for independence, but divided over the place they give to independence in their order of priorities, the arguments used to defend it, as well as their perception of nationalism as a belief-system.
As correntes do agronegócio durante o governo Bolsonaro: divergências e acordos em questões socioambientais
Authors: Pompeia Caio
Published: October 2023

Durante o governo de Jair Bolsonaro (2019-2022),
houve um impulso à diversificação de posições de atores do agronegócio
sobre questões socioambientais. Esse movimento esteve relacionado ao
avanço de agendas antiambientais e anti-indígenas, por um lado, e às
críticas que se ergueram contra elas, por outro lado. Focado no
quadriênio da presidência do líder da ultradireita no Brasil, este
artigo historiciza e analisa a atuação política de distintas correntes
do agronegócio em relação às referidas questões. A pesquisa é baseada
em documentos e manifestações públicas, observação participante em
fóruns do agronegócio e no Congresso Nacional, e entrevistas com
líderes empresariais e políticos. Os resultados indicam que a
diversificação de posições não implicou, contudo, rompimentos
significativos entre as correntes nos principais espaços de decisão
política do agronegócio no Brasil.

Students’ perception on cadaveric dissection in learning gross anatomy for clinical application: Development of a tool using DELPHI technique
Authors: Chenthuran T. , Sivaganesh S. , Abirami C. , Thujeevan J.
Published: October 2023

Anatomy remains key for learning other disciplines in medicine and forms the basis for good clinical practice. Gross Anatomy is an integral part of anatomy curriculum which is taught through different teaching methodologies including cadaveric dissection. This method has many advantages as well as limitations. Since the attendance for gross anatomy practical is compulsory for the students for medical institutions such as that of University of Jaffna, Sri Lanka, the actual perception of students towards dissection is not known. In addition, perception of students towards application of learnt gross anatomy in the clinical setting is important in designing / reviewing the anatomy curriculum. Thus, the main objective of this study was to develop a tool to measure the students’ perception on cadaveric dissection in learning gross anatomy for clinical application.A two round - DELPHI survey was chosen to develop a tool by establishing consensus among experts. Extensive literature survey was carried out to obtain relevant input to prepare the draft of the research tool. The participated experts were professors in anatomy, surgery, English language and medical education. A six – point Likert scale tool was finalized subsequent to two rounds of DELPHI technique, and its subsequent application among thirty recent graduates. Anonymity was maintained throughout the whole process.

Published: October 2023

Objective: This review aims to evaluate the trends, teaching-learning practices, strengths, limitations, and outcomes of the blended-learning approach in Anatomy education in undergraduate programmes in Medicine.Methods: An electronic search for literature was done in the MEDLINE database. Original research articles on blended learning in Anatomy, in undergraduate medical programmes, published in English, and available in full text were included, and narrative description and synthesis were done.Results: Seventeen articles were reviewed, and the majority were published in 2021 and 2022. Blended learning was used in all components of Anatomy courses with different combinations of face-to-face and online teaching-learning methods. Commonly cited benefits of blended learning were higher knowledge acquisition and consolidation, improved self-directed learning, flexibility in time, place and pace of learning, increased motivation, higher level of engagement, and more opportunities to review. The main problems were related to connectivity and interactivity during online instruction. Blended learning courses have generally improved the course outcomes in terms of students’ cognitive gain, especially at the knowledge and comprehension level.Conclusion: Several recommendations were derived from this review. These include proper needs analysis and planning, increasing awareness and provision of training to students and teachers, developing support systems for students and teachers, and continuous monitoring and review of the courses. The need for collaborative planning and development of learning material and teaching-learning activities, with appropriate quality and quantity of the content, systematic and timely delivery and regular evaluation and review were recognized. These recommendations will be useful in planning and successful implementation of blended learning in Human Anatomy courses in medical undergraduate programmes.

Published: October 2023

Objective: The "Purana" population in Sri Lanka, a genetically distinct group with origins in the Sinhalese Kings of the 5th century A.D, lives near the Sigiriya Bolder Garden complex. Limited evidence exists on the prevalence of overweight and obesity among this population. This investigation aims to study the prevalence of overweight and obesity among adult "Purana" individuals.
Methods: Purana villagers in Talkote, Pidurangala, Diyakepilla, and Nagalaweva, near the Sigiriya Bolder Garden complex were selected for the study and 107 men and 199 women were recruited to the study based on ancestry, with Purana pedigrees traced back at least three generations. Informed consent was obtained from participants. A single observer recorded height, weight, and mid-waist circumference measurements of selected individuals. Each measurement was repeated three times and the mean values were taken. BMI values were calculated and obesity, overweight, malnutrition of each individual was determined by using calculated BMI and waist circumference based on global and South Asian cutoff values.
Results: 33.6%, 55.1%, 9.3% and 1.9% of the male adult population was underweight, normal weight, overweight and obese respectively concerning global BMI cutoffs. 33.6%, 43%, 20.6% and 2.8% of male adult population was underweight, normal weight, overweight and obese respectively concerning Asian BMI cutoffs. 17.6%, 62.3%, 17.6% and 2.5% of female adult population was underweight, normal weight, overweight and obese respectively concerning global BMI cutoffs. 17.6%, 49.7%, 24.1% and 8.5% of female adult population was underweight, normal weight, overweight and obese respectively according to Asian BMI cutoffs. 28% of males were obese while 47.2% of females were obese with reference to waist measurements.
Conclusions: In comparison to the urban populations in Sri Lanka, the male and female Purana inhabitants of Sigiriya showed a low prevalence of overweight and obesity.
Research on Fresh Produce Sales Prediction Algorithm for Store Based on Multidimensional Time Series Data Analysis
Authors: Li Zhiyu , Yu Wei , Zhu Wenwei , Wan Haojie , Peng Jingjing , Wang Hui
Published: October 2023

INTRODUCTION: Fresh produce is a daily necessity; however, offline stores often rely on personal experience for purchase, which is highly subjective and may result in inaccurate estimation of purchase quantities. This can lead to produce wastage and subsequently impact the profitability of business. This paper introduces a fresh produce sales prediction model, which can predict fresh produce sales by analyzing multidimensional time series data that influence sales. This model aims to provide guidance for fresh produce purchase in offline stores.OBJECTIVES: The purpose of this study is to predict fresh produce sales by analyzing multidimensional time series data that influence sales. This aims to provide a basis for fresh produce purchase in stores, reduce produce wastage, and enhance business profitability.METHODS: This paper proposes a fresh produce sales prediction model by analyzing multidimensional time series data that affect store sales of fresh produce. An essential component of this model is the ARIMA-LSTM combined prediction model. In this study, the weighted reciprocal of errors averaging method is selected as the weight determination method for the ARIMA-LSTM combined prediction model.RESULTS: In this paper, the ARIMA-LSTM combined model is used for prediction in two scenarios: when the single-model prediction accuracy is superior and when it is inferior. Experimental results indicate that in the case of lower accuracy in single-model prediction, the combined prediction model outperforms, improving prediction accuracy by 3.86% as measured by MAPE. Comparative experiments are conducted between the fresh produce sales prediction model proposed in this paper and time series prediction framework Prophet, traditional LSTM model, and ARIMA model. The experimental results indicate that the proposed model outperforms the others.CONCLUSION: The fresh produce sales prediction model proposed in this paper is based on multidimensional time series data to predict fresh produce sales in stores. This model can accurately predict the sales of fresh produce, providing purchase guidance for fresh produce stores, reducing fresh produce wastage caused by subjective purchasing factors, and increase business profits.

Published: October 2023

The 21st Century was full of innovation when it came to the Tech Sector alone, be it the introduction of the Iphone, or the launch of the big conglomerates such as Facebook and Twitter. The 21st Century gave rise to the concepts of the Curved Displays on phones and the Foldable phones. There were numerous problems which were associated with the flat screen displays, and the shortcomings have been overcome by the Curved Displays and the Foldable phones as discussed in the paper. They have revolutionized the Technological market since their launch. Many Conglomerates such as Samsung, Honor, Xiaomi have invested millions of dollars in availing this new technology. However, currently Samsung has the lead over all its Chinese competitors, and with different companies investing in the new technology, the competition is predicted to become more intense. This will surely give customers a huge variety of phones to choose from. However, this technology did not come without its drawbacks. There were multiple issues associated with the Foldable Phones such as the weight associated with the phone when folded, the tensile strength of the Foldable phones is very low, and the User Interface is not something one could get excited about. Similar issues existed with Curved Displays as well, including costly repair costs, and it is harder to get a grip on compared to the Foldable phones due to the thinning of the edges. The paper discusses in depth the shortcomings of all the types of Phones, as well as which would be the best fit for the user, along with the current trend of the users, and what the Future holds for this segment of Technology.

Published: October 2023

The effectiveness of power utilized by electronic devices is crucial for various reasons. Firstly, high-quality power results in better efficiency, allowing devices to operate at optimal energy levels. This article aims to clarify the significance of Power Quality by highlighting the benefits of using a Dynamic Voltage Restorer (DVR) to improve power quality for electricity consumers. The proposed method employs a hysteresis voltage control system that operates with variable switching frequency to enhance DVR reliability and ease of operation. Using a Tilt Integral Derivative (TID) controller, a type of fractional order controller similar to the PID controller, voltage compensation under disturbances is achieved with satisfactory results demonstrated via simulation. The primary objective of this project is to mitigate power quality issues such as voltage swell and sag in a distribution power system by enhancing power quality with a TID controller and comparing the results with those obtained from a previously implemented PID controller, using MATLAB software. Keywords: Dynamic Voltage Restorer (DVR), Tilt Integral Derivative controller (TID), Total Harmonic Distortion, MATLAB software.
Effect of Electrical Connection on Thermal Propagation of Parallel
Battery Module
Authors: Liu Lei , Kuang Nannan , Hu Jian , Liu Sanbing , Liu Dinghong , Dong Wenkai , Yang Peixia , Liu Anmin , Peng Peng
Published: October 2023

Electrical connection plays an important role in not only direct heat transfer,
but also the transmission of electric energy and the transformation of
electrothermal effect in the parallel battery modules. The thermal propagation
simulation research model was established based on the equivalent circuit and
thermal runaway experimental research of a module formed by four parallel cells,
which superimposes the discharge process and corresponding electrothermal effect
in the process of thermal runaway and thermal propagation, and pays attention to
the SoC (state of charge) state and corresponding thermal runaway energy release
changes after cell discharged. Thermal runaway and propagation characteristics
of parallel and non-parallel battery modules were analyzed and results showed
that without considering the energy exchange between the system and the
environment, the parallel battery module will accelerate the process of thermal
propagation. Further analysis shows that the relationship between the stored
electric energy and the thermal runaway energy of battery cells is the key
factor affecting the thermal propagation rate of parallel battery module. If the
slope of the stored electric energy of the cell changing with SoC is greater
than the slope of its thermal runaway energy changing with SoC, the parallel
circuit will accelerate the thermal propagation process. If the slope of the
stored electric energy of the battery changing with SoC is less than the slope
of its thermal runaway energy changing with SoC, the parallel circuit will delay
the thermal propagation process.

Health Care Providers' Factors Influencing the Effectiveness of Handover of Critically Ill Patients in Intensive Care Units in the Western Region of Kenya
Authors: Odhiambo Judith Seka , Ochanda Damaris A. , Okoth John M.
Published: October 2023

Background: Handover involves the transfer of health care providers' responsibility and accountability for some or all aspects of care for  a patient, or groups of patients, to another clinician or nurse on a temporary or permanent basis with communication being a major  factor for the transfers. Effective handover is essential for safe health care and should used in all clinical situations. In Western Kenya,  there is little evidence of studies carried out on the effective handover of critically ill patients in ICUs.

Material and Methods: A cross-sectional mixed method was adopted and administered to the selected study participants from the  selected hospitals using a self-administered questionnaire and KII tool. The purposive sampling method was used to select the  institutions while convenient sampling was used to pick 80 study participants. Quantitative data was collected by use of questionnaires  and observation checklist while qualitative data was collected through key informant interviews and analysis was done thematically. 

Findings: Health Care Provider variables including gender, age group, cadre, level of education and years of experience in working in the  ICU showed no statistically significant association with the handover of critically ill patients. The mean age of the study participants was  34 years. In addition, the handover performance of Health care providers (p=0.3) and those with higher diploma qualifications (p=0.2) was  up to 11.8 and 18 times more likely to be effective in clinical handover.

Recommendation/Conclusion: While the identified health  care provider factors have no statistical significance to clinical handing over, having a higher diploma, being a nurse, having less than or  equal to seven years of working experience and receiving formal training on clinical handover have been shown by this study to be  beneficial for clinical handover. The study recommends further investigation into these factors through rigorous studies involving a  larger sample size. The lack of formal standardized guidelines for clinical handover and training calls for the urgent need to establish  standard guidelines and processes that can support clinical handover.
Glycogen Storage Disease Type III Presenting as Recurrent Seizure Disorder in a Second Twin: A Case Report
Authors: Jahun Mahmud Gambo , Umar Umar Isa
Published: October 2023

Glycogen storage diseases (GSDs) are a group of genetic autosomal recessive metabolic disorders resulting from deficiencies of enzymes  of glycogen metabolism occurring in the liver, muscles or kidneys. Various types and sub-types exist based on genetic classification  presenting with symptoms and signs of hypoglycaemia, hepatomegaly and myopathy depending on severity, and age of onset. A high  index of suspicion is required for the diagnosis of GSDs. An eighteen-month-old girl who was apparently healthy with normal  development was without any abnormality until about 12 months of age when she had the first episode of afebrile seizure which was  treated with sodium valproate but continued to have occasional seizures. She had a status seizure, which was only aborted with a glucose  infusion. Intra-ictal incident glucose level was 1.4mmol/L. Biochemical investigation revealed deranged liver enzymes, normal  serum cortisol, C-peptide and insulin. Liver histology showed features consistent with GSD III and diagnosis of glycogen storage disease  type III was made based on the liver histology and other supportive laboratory features. Following dietary management, the child  responded very well, was seizure-free and off anticonvulsant therapy. This case highlights the occurrence of symptomatic seizures due to  factors other than epilepsy.

Globally, there is a growing desire to deliver sustainable infrastructure projects. However, the implementation of sustainable construction  in Nigeria is still in its early stages. It is believed that the successful adoption of sustainable construction in Nigeria depends,  in part, on the understanding of sustainable construction among professionals in the architecture, engineering, and  construction (AEC) industry. This study argues that the extent to which AEC professionals demonstrate a clear understanding of  sustainable construction reflects their knowledge and provides a starting point for effective implementation in the future. By focusing on  the current efforts of the Nigerian AEC industry to embrace sustainability, this study aims to identify key factors that exemplify the  understanding of sustainable construction among professionals. A survey was conducted among 290 registered construction  professionals in Abuja. The data was analysed using factor analysis and partial least squares structural equation modelling (PLS-SEM)  approach. The result from the analysis shows seven factors: awareness, political factors, passive culture, knowledge, demand, financial,  and attitude. These factors characterise sustainable construction practices understanding among AEC professionals in Abuja. This serves  as a foundation for future implementation of sustainable construction practices in Nigeria in line with the views of many sustainable  construction researchers.

There has been several ambitious housing policies in Nigeria spanning across pre and post-independence aimed at addressing the  growing housing deficit using the concept of Mass Housing Programmes (MHPs), including the recent MHPs in the Nigerian Economic  Sustainability Plan- (NESP) (2021-2025). However, implementation of the policies has not addressed the housing deficit because records  confirmed the low performances of MHPs whereby only a fraction of the units intended to be built are delivered. The strategy for  implementing the MHP is that, implementation institutions are to utilise Estate Developers (EDs) such as Housing Corporations (HCs) to  drive the successful execution of the projects and based on the scale of the MHP in the NESP, the capacity of EDs in general and HCs specifically will have implications on its success. As such, this study was designed to ascertain the implications of HCs capacity towards  successful delivery of MHPs in Nigeria. A Case Study Research design was used to collect data from HCs of six North-West states in  Nigeria using an interview. Data was analysed using a single case and crosscase technique. Results revealed that the experiences in the  practices of HCs in MHPs has the potentials to: reduce project cost; reduce project time; increase clients’ satisfaction; and develop human  resource. It was concluded that the HCs in North-West States possess capacity to successfully deliver MHPs such as the NESP and  future National Housing Programmes (NHPs). Based on the findings of this research, the study recommends that the vulnerability of HCs  should be studied to get a more encompassing picture of performance potentials in successfully delivering MHPs. Furthermore, a more  comprehensive study should be undertaken to cover the HCs across Nigeria to get information that could enable their optimal  integration into MHPs. The implication of the findings is that, since the HCs demonstrated some capacities to deliver MHPs, EDs can  successfully delivered MHPs if other enabling factors that are key to delivery of MHPs such as finance, among others are put in place. The  limitation of the study is that the study covers only six HCs, thus, generalisation of the findings could be limited.

Published: October 2023

The effect of Udzungwa Mountain National Park (UMNP) on the livelihoods of communities is important.National Park is crucial in supporting the livelihoods of communities socially, economically andenvironmentally. This article analyzes the contribution and importance of the management of UMNP on thelivelihoods of communities in Kilombero District in Morogoro Region. This paper adopted mixed researchapproach where data were collected using questionnaires, interviews and observations. Data were collected inthe villages’ proximity to UMNP; Msosa, Msolwa, Mkula and Ruipa villages. A total of 233 heads of householdswere interviewed. The results showed that, heads of households were motivated to manage the park because ofthe benefits accrued from it. People managed the park because they get firewood, poles, water and othersbenefits. This paper adopted Sustainable Livelihoods Framework (SLF). SLF is a useful tool for analyzing thecontribution of UMNP to livelihood of the communities residing close to it. The livelihood supports offered byUMNP among others include income, improved food (forest vegetables), fruits and improved well-being.Challenges encountered in the management of UMNP among others include climate change, deforestation,cutting trees for building houses, wildfire, illegal collection of herbs for medicines, poaching and illegal hunting.The study concludes that, fringe communities must be motivated to manage the park because of the continuingbenefits accrued from it. The study recommends that communities should be encouraged to take measures toprotect, conserve and participate in the management of UMNP.

Staff competency is a key factor in ensuring an organization performs and delivers on her mandates. Both professional and academic are important indicators of competency and it evolves over time in line with presenting scenarios. A mismatch between staff competencies and deployment creates apathy towards work which greatly compromises performance. At Masinde Muliro University of Science and Technology for instance, in the first half of the financial year 2021/2022, about 3% of employees left the service in search for greener pastures elsewhere. This was largely due to job dissatisfaction arising from improper deployment among other reasons. This study was conducted to establish the relationship between staff qualifications and competencies vis-à-vis deployment and the extent to which this relationship affected staff performance. A Mixed Methods Research Design, allowing a blend of both quantitative and qualitative paradigms was employed. A cross-sectional design was adopted as the study targeted a cross-section of staff across all cadres. Results show that while a majority of staff are qualified for the various assignments they are assigned to perform, a small proportion do not have the requisite skills. This could be explained by the fact that the University has not fully operationalized her HR manual and therefore the machinery for measuring staff performance is weak and needs improvement. Further, it is also evident that apart from academic qualifications, professional training is equally vital. There is therefore need for continuous professional training which should equip staff with the most current skills needed for effective delivery of services.
