Shabine and Other Stories
Authors: Simmons-McDonald Hazel
Published: October 2023

In this impressive first collection of short stories, Hazel Simmons-McDonald presents a deft exploration of class, of how values are shaped by religion, and of the tensions that undergird family life. She makes a place for voices hitherto not heard and creates characters who closely guard the secrets of their hearts but who through her narrative dexterity come to experience moments of truth and clarity of memory. Simmons-McDonald’s energetic prose not only captures the polylinguistic character of St Lucian society but it also creates a space for the exploration of an Eastern Caribbean brand of magical realism. With polished assurance, she weaves folk beliefs into the fabric of her stories, creating memorable tales marked by notes of sadness yet balanced by tenderness and joy. Simmons-McDonald takes the reader on a journey where the familiar and the unfamiliar sit side by side, where the spirit world is always present, and where at all times we are reminded of the universal reach of love and hope. “I cannot think of a single work with such a wide and complex appeal. While many West Indian writers . . . explore the same worlds as Hazel Simmons-McDonald, none of them bring out the issues of childhood and family intertwined with religious, environmental, and social conditions with such surgical grace. The calmness of the style leads the reader into worlds of joy, or pain and horror made visible and bearable by the calculated moderation, exactitude, and poignancy of the diction.”—Jean D'Costa, Leavenworth Professor of English Emerita, Hamilton College
The Breadfruit Germplasm Collection at the University of the West Indies, St Augustine Campus
Authors: Roberts-Nkrumah Laura B.
Published: October 2023

“This book is a report on the major effort made to establish a breadfruit germplasm collection at the University of the West Indies, at St Augustine, Trinidad and Tobago, and to describe each cultivar in the collection. Cultivars are from the Pacific islands and the Caribbean. This effort is highly commendable because breadfruit, among its various attributes, can be a valuable and staple source of food, yet information on this tree crop is sparse. This is not surprising as it takes several years to collect reliable data on tree crops, and breadfruit has been a neglected, underutilized crop. “As with any other crop, certain breadfruit cultivars grow better under some environmental conditions, are more resistant to pests and diseases, and are more suitable for various types of processing, than other cultivars. The detailed descriptions of the morphology and other characteristics made by Laura Roberts- Nkrumah are essential steps for identifying and selecting suitable cultivars for the desired purpose – for use as fresh or frozen food, for processing into flour or chips, for soil conservation and so on. “This book is useful in making any Ministry of Agriculture in the tropics, other agricultural-related organizations and institutions, and individuals aware of the diverse characteristics of breadfruit and thus select cultivars which are suitable for the intended purpose. In addition, if persons would like to have already-established cultivars identified, until DNA profiles are available, this book explains how relevant measurements can be taken, and observations made, which can then be submitted to the author for identification of the cultivar. The clearly described methods and the accompanying high-quality photographs greatly facilitate the collection of the data.” —Phyllis L. Coates-Beckford, Professor Emeritus of Plant Pathology, the University of the West Indies, Mona, Jamaica.

Social Studies Curriculum And Methods for the Caribbean
Authors: Griffith Anthony D. , Barth James L.
Published: October 2023

Developments in the teaching and learning of social studies over the years point to a conceptual focus on the active study/investigation of significant social issues and concerns. While knowledge of these issues is important, equally so are the requisite skills and competencies that are required to enable the student to examine and analyse the issues and to make decisions about them. This handbook is therefore intended to project the teaching and learning of social studies as the development and acquisition of skills for the study of social issues or phenomena. These skills relate to gathering information, analysing and evaluating information, critical thinking, problem solving and decision making, as well as social and interpersonal skills. The focus is on activities, practice and authentic learning. The content is organized into thirteen chapters, which may be used in sequence or can, equally well, stand alone. The chapters can also be used individually in workshops or seminars. the teacher-training institutions throughout the Caribbean, as well as for students in degree programmes in social studies in the Schools of Education at the University of the West Indies. Classroom teachers of social studies will also find the book very useful as a reference source.

Cocreation of the Tourism Experience at International Sport Tourism Events
Authors: Mascarenhas Margarida , Alves Joana , Pereira Elsa , Martins Rute
Published: October 2023

The cocreation of the tourist experience in sporting events has received little scientific attention. This study aimed to analyze the influence of cocreation of the tourist experience on the memorability of the experience through the attention and involvement of sporting event tourists,
and to verify whether this influence changes with the type of experience (i.e., active participant vs. spectator). A total of 356 questionnaires was collected at two international cycling events held in Portugal in 2021. The data were analyzed with structural equation analysis and a Mann–Whitney
test. Cocreation influences attention and involvement, which, in turn, help to explain the relationship between cocreation and memorability, highlighting differences between the two types of experience. For the first time, the on-site cocreation model was applied to sport tourism events. In
this touristic context, experiences must be developed through a customized approach based on the creation of hedonic and eudaimonic experiences.
The Psychological Wellbeing among the Adults Raised in Children’s Homes in Kenya
Authors: Ahmed Hamida , Waithima Charity , Karume Michelle
Published: October 2023

The institutionalisation of children has been seen to increase the risk for emotional, developmental, cognitive and attachment disorders later in life. Transitioning out of institutionalised care and integrating into the outside world has been found to be a difficult experience for many care leavers. Some of them are not prepared to face the outside world, feel neglected and lack a support system. Some may experience socio-emotional distress owing to a lack of necessary social skills in life outside the institutions. The study purposed to assess the psychological wellbeing of adults who were raised in children’s homes and other institutional care in Kenya and had since transitioned out. The descriptive survey design was employed to undertake the quantitative data with a census approach used to sample 294 (F =154, M =140) respondents. Ryff’s scale of psychological wellbeing was the adapted research tool for data collection. The study results revealed that environmental mastery (M =23.46, SD = 7.47) was the highest-scored domain of psychological wellbeing. This was followed by personal growth (M = 23.14; SD = 7.52) and then purpose to life (M =20.74, SD = 6.58). The study had a mean of 21.31 (SD = 7.15), interpreted as being moderate psychological wellbeing among the care leavers. Based on the findings, organisations that support care leavers ought to create awareness and offer psychological support to care leavers. They can also collaborate with children’s homes and other stakeholders to offer periodic training on promoting psychological wellbeing among children in care and care leavers. This is especially so in regard to the poorly scored domains such as personal growth, autonomy, and self-acceptance

Authors: Kamanzi Lydia Muthili , Muiru Anne , Thinguri Ruth
Published: October 2023

There is a worldwide concern on academic dishonesty particularly in the third world countries. The main purpose of this study was to scrutinise the effects of students’ peer pressure on academic dishonesty in public secondary schools in Makueni County, Kenya. The study was based on the Psychosocial Dynamic Theory and the Theory of Planned Behaviour. The study employed mixed methodology and the concurrent triangulation design. The sample size of 802 consisted of 750 students sampled randomly, 25 principals and 25 teachers, both sampled purposively. The study utilised 1 SCDE and 1 CDE purposively sampled. The instruments employed were questionnaires for principals, teachers, and students and interviews for the education officers. Descriptive data was scrutinised using frequencies and percentages and presented through tables and figures. Inferential statistics was examined using linear regression and presented through tables, while qualitative data was analysed thematically and presented through narration and verbatim citations. The investigation results were that peer pressure implicitly impacted academic dishonesty. The investigation established that there was a need to improve the students’ peer pressure. It was recommended that engaging participation, such as the introduction of skilled, well-informed, and competent counsellors in the institutions, was mandatory to eliminate academic dishonesty cases during the examinations

Published: October 2023

This study was proposed to analyze farmers’ varietal perception of bread wheat. From Meket district, four kebeles were randomly selected to achieve the above objective. The study uses cross-sectional data collected from randomly selected 214 farming households through an interview schedule. Fourteen Likert items were included in two categories as advantages and disadvantages of the technology.  Five-point Likert scale was used to analyze varietal perceptions. One-way ANOVA was employed for testing the overall mean differences among bread wheat technology adoption categories. In addition, the Relative Importance Index (RII) was used to analyze item relative importance. Farmers supported improved bread wheat varieties for specific attributes such as, high marketability, early maturity, better grain yield, grain color, food quality, and storability were found to be taking the average score of 4.43, 4.43, 4.33, 4.01, 3.85, 3.45, and 3.26, respectively. Whereas, improved bread wheat varieties were perceived to be unsuitable for shattering problems, straw quality, and low yield performances in poor soil types. Therefore, breeding objectives should be oriented towards improving bread wheat variety traits related to shattering and straw quality. Limitation of labor is one of the major reasons for the low adoption rate of row planting. Hence, machinery should be carried out to promote row planting of bread wheat. Moreover, the study indicates the need to entertain farmers’ perception of bread wheat technologies for creating wider adoption.

Mandailing Natal district as the second largest district in North Sumatra Province has great potential for horticultural development. This study aimed to determine the sustainability level of horticultural development in Mandailing Natal district through 5 dimensions, namely ecological, economic, social, technological and institutional. The RAPFISH-MDS analysis method was used to measure the index and sustainability status. The results showed that the criteria for the sustainability of horticultural development in Mandailing Natal district was quite sustainable (52.61) with the sustainability index value of the ecological, institutional, social, economic and technological dimensions, respectively, 58.06; 56.86; 53.76; 51.99; and 51.08. Sensitive attributes supporting sustainability are erosion rate for the ecological dimension, post harvest management for the economic dimension, extension intensity for the social dimension, land management technology for the technological dimension, and conflicts between farmer groups for the institutional dimension. The realization of horticultural development can be through the development of government programs and extensions that change farmers' perceptions of the environment and the application of eco friendly technologies in their farming.
Application of Biogas with Fermenting Bacteria from Manure Raw Material on Stoves and Generators
Authors: Yulianto Rudy , Sukardi Sukardi , Rusli Meika Syahbana , Ningrum Sari Sekar
Published: October 2023

The raw biogas from the digester is a gas produced by bacterial fermentation which has a composition of methane (CH4), carbon dioxide (CO2), hydrogen sulfide (H2S), water vapor, and various other gases. Gases other than methane in raw biogas can damage the combustion system if used directly. The digester that produces biogas is used to move the generator engine using raw materials, such as cow feces, goat feces, fowl feces, straw, husks, and clean water. In the mixing process, all the raw materials are stirred or mixed evenly in the digester. Next is the process with five stages, namely (1). In the first stage: on the 11th day, adding clean water and fermentation carried out for 21 days, (2). The second stage: adding starter, hormones, charcoal flour, cow feces, fowl fees, goat feces, straw, and husks, then fermented for 7 days. (3). The third stage: adding a starter and fermenting it for 7 days. (4). Fourth stage: ready-to-use compost or solid fertilizer is ready to produce. (5). Fifth stage: liquid fertilizer is ready for production. In the gathering stage: all raw materials are stirred or mixed evenly in the digester and fermented for 1.5 months to become biogas. The last stage is the distribution of biogas: for household needs, and generators. From this research, it can conclude that the water column height (h) is 10.42 cm, and the maximum water column height is 9 cm so that the reactor is safe and the maximum pressure that can be attained is 879.1918 kg.m-1.s-2. The heating rate for ratio A is 0.0600 oC.s-1 and the heating rate for ratio B is 0.0640 oC.s-1. The calorific value produced from heating 1 liter of clean water using biogas from ratio A is 297.99315 kJ, and the calorific value of ratio B is 288.9174 kJ. With a compressor pressure of 8 psi, biogas can be inserted in this using a freon tube for a maximum of 6000 seconds with a mass of 6163 grams. In filling biogas, the biogas manometer should show the maximum number (between 16.50 – 25.50).

В статье представлены результаты исследований 2021-2022 гг., проведенных на темно-каштановых почвах Центрального Казахстана, по изучению влияния минеральных удобрений на урожайность гороха сорта Аксайский усатый 55 и динамику основных питательных элементов почвы, таких как нитратный азот, подвижный фосфор, обменный калий в течение вегетации гороха по фазам: всходы; бутонизация и цветение. Посевы вышеуказанной культуры проводились тремя разными нормами высева семян (0,8; 1,0; 1,2 млн.шт. семян на 1 га), в три разных срока посева (11; 15; 20 мая) и по трем фонам: контроль (без удобрений); P 82 кг/га д.в.; P 82 кг/га д.в.+ N 17 кг/га д.в. Содержание нитратного азота в почве перед посевом гороха по всем нормам высева было от очень низкого до повышенного, в зависимости от срока посева и климатических условий. Внесение аммофоса повышало содержание нитратного азота в почве по всем срокам и нормам высева гороха: до 16,6-17,5 мг/кг на вариантах со сроком посева 11 мая и до 28,1-37,5 мг/кг почвы на вариантах с более поздним сроком посева. Дополнительное внесение сульфата аммония соответственно еще больше увеличивало содержание нитратного азота в почве - до 40,5 мг/кг почвы. Содержание подвижного фосфора в почве перед посевом гороха на контрольных вариантах (без удобрений) было очень низким и низким на уровне 8,8-23,5 мг/кг. Внесение аммофоса как фосфорсодержащего удобрения повышало содержание подвижного фосфора в почве до 38,1 мг/кг почвы, что соответствует повышенной обеспеченности.
В среднем за два года проведенных исследований, наиболее высокая урожайность –20,26 ц/га, получена по варианту со сроком посева 20 мая, с нормой высева 1,2 млн.шт. семян на 1 га, с внесением P 82 кг/га д.в.+N 17 кг/га д.в. Более оптимальным оказался третий срок посева - 20 мая, который обеспечил наиболее высокую урожайность изучаемой культуры – 20,26 ц/га.

O objetivo desta pesquisa foi associar duas ferramentas de análise, indicador de desenvolvimento regional e geotecnologias, para a identificação da dinâmica de produção da mandiocultura paraense no intervalo de 2009 a 2019. Os dados foram obtidos por meio da base de informações sobre produção agrícola municipal (PAM) disponibilizados pela plataforma do Instituto Brasileiro de Geografia e Estatística (IBGE), por meio do Sistema de Recuperação Automática (SIDRA). As informações foram organizadas em tabelas para a aplicação dos seguintes métodos de análises: identificação do grau de especialização da produção de mandioca por meio do indicador Quociente Locacional (QL) e determinação das principais regiões paraenses por meio do mapeamento coroplético. Com base nos resultados obtidos, foi possível indentificar microrregiões com elevada concentração (QL) na produção de mandioca no estado do Pará, entretanto, apenas o mapeamento coroplético permitiu a identificação das maiores regiões produtoras. Deste modo, a combinação de métodos de análises permitiu uma melhor caracterização do comportamento desta cadeia de produção.
Coal Dust Severity in a Power Plant: In-Situ, Analytical, and Numerical Assessments
Authors: Mohammad Nurizat Rahman
Published: October 2023

One of the most serious occupational hazards in the coal industry is coal dust. Previous research revealed that the vast majority of coal dust assessments were conducted in coal mines, resulting in a lack of understanding of the severity of coal dust during coal handling activities in power plants. Therefore, the severity of combustible coal dust in one of Malaysia's power plants was assessed using a comprehensive analysis that included qualitative observations, in-situ measurements, numerical simulations, laboratory tests, and data analysis. The designated locations include the coal conveyor hall (Zone 1, 2A, and 2B), milling (Zone 3), and bunkering areas (Zone 4). Relevant safety limits, as recommended in National Fire Protection Association (NFPA) 654, were used as guidelines where comparisons with the site data were made. The high coal dust accumulation rate in Zone 1 was revealed to be largely the result of inefficient ventilation performance, as confirmed by in-situ measurement and numerical simulation. Direct referencing to the relevant NFPA 654 guidelines finds the zones encompassing the coal conveyor hall are at “high risk” of fire and explosion. Further laboratory assessments on the dust samples in Zone 1 however reduces the earlier assessment to “medium risk” with the potential of “low risk” with regular housekeeping. Zones 3 and 4 were found to be “low risk” areas due to insignificant accumulation and good air flow management. Overall, the evaluation of the severity of combustible coal dust was successful in establishing the risk mapping for all zones. Cleaning frequencies were also proposed based on the coal dust accumulation rates and the risk mapping.

Dependence of Stellar Differential Rotation on Effective Temperature and Rotation: An Analysis from Starspot Transit Mapping
Authors: Araújo Alexandre , Valio Adriana
Published: October 2023

Stellar rotation is crucial for studying stellar evolution, since it provides information about age, angular momentum transfer, and magnetic fields of stars. In the case of the Sun, due to its proximity, detailed observation of sunspots at various latitudes and longitudes allows a precise estimation of the solar rotation period and its differential rotation. Here, we present for the first time an analysis of stellar differential rotation using starspot transit mapping as a means of detecting differential shear in solar-type and M stars. The aim of this study is to investigate the relationship between rotational shear, ΔΩ, and both the star's effective temperature (T
eff) and its average rotation period (

P

¯

). We present differential rotation profiles derived from previously collected spot transit mapping data for 13 slowly rotating stars (P
rot ≥ 4.5 days), with spectral types ranging from M to F, which were observed by the Kepler and CoRoT satellites. Our findings reveal a significant negative correlation between rotational shear and the mean period of stellar rotation (correlation coefficient of −0.77), which may be an indicator of stellar age. On the other hand, a weak correlation was observed between differential rotation and the effective temperature of the stars. Overall, the study provides valuable insights into the complex relationship between stellar parameters and differential rotation, which may enhance our understanding of stellar evolution and magnetic dynamos.

   \begin{document}$ \begin{equation*} \Upsilon_{n+1} = \frac{\Gamma_{1}+\delta_{1}e^{-\Psi_{n-1}}}{\Theta_{1}+\Upsilon_{n}}, \ \Psi_{n+1} = \frac{\Gamma_{2}+\delta_{2}e^{-\Omega_{n-1}}}{\Theta_{2}+\Psi_{n}}, \ \Omega_{n+1} = \frac{\Gamma_{3}+\delta_{3}e^{-\Upsilon_{n-1}}}{\Theta_{3}+\Omega_{n}}, \end{equation*} $\end{document}

for $ n\in \mathbb{N}_{0} $, where the initial conditions $ \Upsilon_{-j} $, $ \Psi_{-j} $, $ \Omega_{-j} $, for $ j\in\{0, 1\} $ and the parameters $ \Gamma_{i} $, $ \delta_{i} $, $ \Theta_{i} $ for $ i\in\{1, 2, 3\} $ are positive constants.
High-order rational-type solutions of the analogous (3+1)-dimensional Hirota-bilinear-like equation
Authors: Li Wenting , Jiao Ailing , Liu Wei , Guo Zhaoying
Published: October 2023

In this article, a new dynamical system equation named the (3+1)-dimensional Hirota-bilinear-like equation (HBLE) was constructed. The generalized Hirota bilinear method was applied to obtain this new HBLE in (3+1) dimensions. This new HBLE possesses a similar bilinear form to the original (3+1)-dimensional Hirota bilinear equation, but with additional nonlinear terms. A set of high-order rational solutions is constructed for the given equation, generated from polynomial solutions to the associated generalized bilinear equation. The analyticity conditions of the resulting solutions were investigated and six groups of general solutions were derived. In addition, the shape and surface of the high-order rational function solutions and their dynamic behaviors were studied by utilizing Maple.
Les fictions du droit
Authors: Kelsen Hans
Published: October 2023

Pour Hans Kelsen, la question des conditions de validité d’une norme juridique d’une part, celle des valeurs qui sont censées inspirer et contrôler le droit positif d’autre part, sont deux questions bien distinctes. C’est la première de ces deux questions, objet de ce qu’il nomme la « théorie pure du droit », qui est au cœur de ces études centrées sur le statut des fictions juridiques - et d’abord sur la nature des fictions en général.

Cette réflexion se développe ici à travers un débat vivant avec le théoricien des fictions Hans Vaihinger, auteur de la fameuse Philosophie du comme si (1911). Deux questions sont particulièrement stimulantes pour tous ceux qui s’intéressent, de près ou de loin, au droit et à la philosophie du droit : 1) Comment le droit positif comme système de normes existantes peut-il trouver sa justification ultime dans une norme fondamentale fictionnelle, dans une « fiction au sens vaihingerien du terme » ? Autrement dit, comment ce qui est positif, factuel, par exemple telle loi ou telle décision de justice, peut-il trouver son fondement ultime dans quelque chose d’imaginaire, qui ne dénote rien dans la réalité ? 2) Quelle est aujourd’hui la pertinence du modèle kelsénien de validation des normes ? Comment peut-il trouver à s’appliquer de manière cohérente dans le contexte du droit européen ?

The medical field is growing at a rapid pace, with new diseases cropping up daily that require invention of appropriate course of treatment. The heart is a muscular organ which is the size of clenched human fist, and is responsible for blood circulation. Also squeezing the classification model with entire raw features can create a bottleneck to the classification performance. Though, heart/cardiac disease is the name given to diseases affecting the heart in general, there are many diseases which come under this name, including coronary artery diseases (CAD), cardiomyopathy, cardio vascular disease (CVD) and so on depending upon the circulation of blood throughout the body. Hence, this research work initiates a hybrid method named HCFFSC- hierarchical clustering fuzzy features subset classification for identifying appropriate feature subsets related to target class and given to classifier model to enhance the performance of health monitoring and management (HMM).

Published: October 2023

As power densification demands are placing electronic packages under greater reliability risk, the consequence of complementary or interacting stresses in producing failure are becoming increasingly significant. As such, it is important that reliability methods and package designs consider how multiple-stress interactions may impact product life. Here, the coordination between a novel accelerated testing method and electronic design automation efforts has demonstrated a successful optimization approach for a wire-bonded 2D module layout combining failure mechanisms of electromigration and mechanical stressing. Utilizing custom, physics-of-failure approaches in accelerated testing, interactions can be observed in failure acceleration, which then can be incorporated into design for reliability (DfR) optimization tools. The PowerSynth 2 platform has been utilized as a design for reliability tool to perform a rapid relative reliability evaluation incorporating multi-stress scenarios. This work demonstrates the value added to reliability evaluation techniques when accounting for interacting failure mechanisms and suggests that next generation power devices consider these effects in lifetime estimation.
