Optimizing Grid Performance in Trinidad and Tobago: The Role of Vehicle-to-Grid (V2G) Technology
Authors: Boodoo Curtis
Published: June 2024

This study investigates the impact of integrating 10,000 battery electric vehicles (BEVs) into the electrical grid of Trinidad and Tobago through three charging scenarios: non-incentivized charging, charging at work, and a Vehicle-to-Grid (V2G) program. The results reveal that non-incentivized charging exacerbates peak demand and grid strain, while workplace charging provides only modest peak demand mitigation. In contrast, the V2G scenario significantly reduces peak load impacts and enhances grid stability by leveraging BEVs as dynamic energy storage units that contribute to grid services during high-demand periods. The study proposes a V2G tariff scheme that includes compensation for battery degradation, aiming to incentivize participation and offset potential costs. Economic analysis shows that while V2G involves higher per-MWh costs than conventional storage technologies, it avoids the need for substantial capital investment in static energy infrastructure, presenting a cost-effective solution for energy management in island nations. The findings highlight the potential of V2G technology to facilitate sustainable energy transitions, emphasizing its role in enhancing grid resilience, optimizing renewable energy usage, and reducing carbon emissions. This research underscores the transformative potential of V2G systems as critical enablers of sustainable energy strategies in regions facing similar challenges to Trinidad and Tobago.

Published: June 2024

Background: The development of critical thinking skills in prospective mathematics teachers is essential for their future effectiveness in the classroom. Understanding how these individuals process and resolve problems that contain contradictory information provides insight into their critical thinking abilities. Previous research has highlighted the significant role of prior knowledge in problem-solving and critical thinking.Aim: This study aims to explore the critical thinking processes of prospective mathematics teachers when faced with problems that contain contradictory information. Specifically, it seeks to determine the influence of prior knowledge on their ability to navigate and resolve these complex problems.Methods:  The study employed a sequential explanatory design. Initially, quantitative data from prerequisite skill and critical thinking tests (specifically, problems with contradictory information) were collected from 68 participants. Simple regression analysis informed the selection of six participants (two each with high, medium, and low prerequisite abilities) for the subsequent qualitative phase. In-depth interviews and problem-solving tasks were conducted, prompting participants to articulate their thought processes. Data analysis focuses on identifying patterns and themes in their use of prior knowledge and critical thinking strategies.Results: The findings reveal that prior knowledge plays a pivotal role in how prospective mathematics teachers approach and resolve problems with contradictory information. Those with a strong foundation in mathematical concepts and problem-solving strategies are better equipped to identify inconsistencies and develop logical solutions. Conversely, participants with limited prior knowledge struggle to reconcile conflicting information and often resort to less effective problem-solving methods.Conclusion: This study underscores the importance of prior knowledge in the development of critical thinking skills among prospective mathematics teachers. Educator preparation programs should emphasize the cultivation of a robust knowledge base and provide opportunities for students to engage in complex problem-solving tasks. By doing so, future teachers will be better prepared to navigate the challenges of the classroom and foster critical thinking in their own students.

Authors: Wicaksono Agung , Prabawanto Sufyani , Suryadi Didi
Published: June 2024

Background: Algebra is one of the most important topics in school mathematics. However, the facts in the field found that there were still many errors made by students in solving problems on linear equations in one variable.Aim: This research aims to describe and analyze students' learning obstacles in one-variable linear equation material.Method: This research used a qualitative research approach with a phenomenological design. This research used a purposive sampling technique, the research subjects were 28 class VIII students of Junior High School in Palu City. Data collection was carried out by triangulating data through description tests, in-depth interviews, and documentation studies.Result: Learning obstacles found in the one-variable linear equation material are categorized into 3 types, namely ontogenic obstacles, epistemological obstacles, and didactical obstacles. ontogenic obstacles are found because there is a leap in students' thinking from an arithmetic mindset to an algebraic mindset. Epistemological obstacles are found due to limited context for students which causes errors in working on questions. Some epistemological obstacles are the concept of linear equations, algebraic operations, and applications to equations. The didactical obstacle was found because the teacher's teaching was procedural so the formation of the concept of one-variable linear equations and inequalities in students did not go well.Conclusion: The importance of initial strengthening is related to students' understanding of coefficients, variables, and constants, providing strengthening of the arithmetic thinking process to algebraic thinking, as well as techniques and methods in delivering material and the teaching materials used.

Authors: Kostikova Anastasiya Vladimirovna , Saykina Yuliya Andreevna , Popova Alexandra Andreevna
Published: June 2024

The methodology of assessing borrowers' credit solvency is being considered and improved by building a combined system of intellectual and economic-mathematical methods. Various methodologies and tools used to assess the creditworthiness of individuals are being investigated: data mining methods, fuzzy algorithms, economic and mathematical methods. In the language of functional modeling, a description of the process of recognizing the client's creditworthiness level is presented, with the help of which the main stages of assessing the credit solvency of clients and their maintenance are determined. As part of the study of the instrumental apparatus, intellectual and economic-mathematical methods have been studied in detail, which can be synthesized into a single system for assessing the credit solvency of borrowers. Based on the fuzzy modeling tools, an algorithm is proposed that allows calculating a complex indicator of the creditworthiness of individuals. The credit solvency rating is determined on the basis of a set of criteria and features that characterize the bank's borrowers with a sufficient degree of completeness. For each selected criterion, linguistic variables “Indicator level” and classification tables are formed, correlating the values of the criteria with its “level”. The analysis of software tools used to assess credit solvency was also carried out, and the choice of an analytical platform for our own practical experiments was justified. On the basis of the Deductor platform, the scoring method, the decision tree method are implemented and a neural network is built. To implement the task of assessing the credit solvency of an individual, the concept of developing an intelligent system is proposed. The individual results of the study and the conclusions obtained can be used by specialists of credit and financial institutions to calculate the rating rating of the borrower. The systematized knowledge can be used in further research on this issue and form the basis for the implementation of the software product.

Published: June 2024

The goal of any progressive society is the sustainable development of organizations. Business growth and sustainability should not come at the expense of future generations. The concept of sustainable development involves making investment and financial decisions while considering their social and environmental impact on both the company and society. Reliable information is crucial in making business decisions and developing a long-term strategy for sustainable enterprise development. Therefore, it is necessary to provide accounting and analytical information on sustainable development factors and related risks to increase the confidence of interested users. Investors and consumers are sensitive to the impact of companies on social and environmental aspects of society. This highlights the importance of defining sustainability assessments and integrating them into the business environment. The lack of information flow or documentation confirming the company's environmental and social orientation can negatively impact its reputation with investors and consumers. Traditional reporting methods used by the organization may not adequately address this issue, as they focus solely on financial indicators. A comprehensive solution to this problem is the implementation of integrated sustainability reporting based on the ESG model. A comprehensive solution to this problem is the implementation of integrated sustainability reporting based on the ESG model. It is crucial to demonstrate the correlation between financial data and sustainability indicators. Introducing an integrated approach to disclosing information on the organization's sustainable development can serve as a tool for corporate governance, brand building, and forecasting new trends. This ultimately contributes to improving business efficiency.

We would like to state well-known Ostrowski inequality via Montgomery identity for ψ−(α, β, γ, δ)−convex function in mixed kind. In addition, we establish some Ostrowski type inequalities for the class of functions whose derivatives in absolute values at certain powers are ψ − (α, β, γ, δ)-convex functions in mixed kind by using different techniques including Hölder's inequality and power mean inequality. Also, various established results would be captured as special cases. Moreover, some applications in terms of special means would also be given.

In this paper, we investigate analytic solutions of higher order linear non-homogeneous directional differential equations whose coefficients are analytic functions in the unit ball. We use methods of theory of analytic functions in the unit ball having bounded L-index. Our proofs are based on application of inequalities from analog of Hayman’s theorem for analytic functions in the unit ball. There are presented growth estimates of their solutions which contain parameters depending on the coefficients of the equations. Also, we obtained sufficient conditions that every analytic solution of the equation has bounded L-index in the direction. The deduced results are also new in one-dimensional case, i.e. for functions analytic in the unit disc.
Keywords: Analytic function, analytic solution, slice function, unit ball, directional differential equation, growth estimate, bounded L-index in direction.

Published: June 2024

Sumatran elephant Elephas maximus sumatranus is a critically endangered species under pressure of habitat fragmentation and human-elephant conflict (HEC) such as in one plantation and/or settlement area next to its natural habitat, Simpang Tiga Abadi, Selapan, South Sumatera.  Due to HEC, local people may experience economic loss and human casualty. Simpang Tiga Abadi is avillage, especially 5 sub-settlements directly close to the production forest area of PT. Bumi Khatulistiwa Mandiri, which is the natural habitat of sumatran elephants. The communities collaborated and company were formed an elephant watch group to monitor and deter sumatran elephants from entering plantation areas and settlements. On the other side, sumatran elephants entering the plantation may give some conservation support as indirect conflict mitigation approaches.   A non-invasive sampling can be done by gathering information on its fecal based genetic diversity and may become one of supporting sumatran elephant conservation efforts.   Under the Center for Applied Science Studies, Sriwijaya University project: "Genetic analysis of the sumatran elephant sub-population in its  habitat pocket in Sugihan- Simpang Heran, South Sumatra", Tropical Forest Conservation Action (TFCA) cycle VIII project, the significant role of local community affected by HEC on gathering information and fecal samples of sumatran elephant entering the PT.   Bumi Khatulistiwa Mandiri plantation was conducted.   Sumatran elephants’ fecal sampling involved the local communities affected by HEC. Its aim is to value the significance of local people’s involvement in finding and collecting dung left by wild sumatran elephants during entering both plantation areas. Data on areas were recorded, and its dung samples were collected for molecular analysis.  Collecting information and mapping the entry points of sumatran elephants were done supported by the Simpang Tiga Abadi community, consisting of sumatran elephant’s entry points, dung presence, individual numbers, and group activities, as well as the damage. Eighteen fecal samples of 5 entry points were collected in 5 days. By doing the assistance, the local communities learnt the benefits and important value of sumatran elephant and its dung.   This research is the first local communities’ indirect step in efforts to conserve sumatran elephants in Simpang Tiga Abadi Village, Selapan, South Sumatra.

Authors: Wu Chih-Ching , Chang Ya-Pei
Published: June 2024

OBJECTIVE

To describe the long-term outcomes, overall survival, progression-free survival, and prognostic factors in dogs with necrotizing encephalitis (NE).

ANIMALS

37 client-owned dogs clinically diagnosed with NE.

METHODS

All dogs underwent MRI and CSF analysis. Cox proportional hazards regression was used to examine factors related to the risk of relapse and death, including signalment, history, diagnostic investigation results, and treatments before the first relapse.

RESULTS

The medians of the overall and progression-free survival times were 639 days (IQR, 342 to 1,482 days) and 233 days (IQR, 111 to 775 days), respectively. Overall survival was highly correlated with progression-free survival. Four dogs (11%) died or were euthanized within 3 months of diagnosis. Relapse within 6 months was associated with a shorter overall survival. However, no prognostic factors for overall survival were found. The category of patients with presenting clinical signs that lasted 29 days to 6 months (OR, 3.26; 95% CI, 1.35 to 7.90) was associated with a higher risk of relapse. Seizures were presented in 75.7% of dogs, with a recurrence rate of 100%.

CLINICAL RELEVANCE

This report provides comprehensive follow-up information for dogs with NE, revealing a fair prognosis and low early mortality rate. Seizure is a very common clinical sign with a high recurrence rate.

Authors: Rossanese Matteo , Brockman Dan , Chanoit Guillaume , Crosby Jilli , Scott Peter , de la Puerta Benito , Dukes-McEwan Joanna , Basili Mattia
Published: June 2024

OBJECTIVE

To describe complications and outcomes in dogs undergoing epicardial pacemaker (EP) implantation, identify factors associated with survival, and investigate improvement in clinical signs and health-related quality of life (HRQoL) following surgery.

ANIMALS

52 client-owned dogs that underwent EP placement.

METHODS

Medical records of 4 UK-based referral hospitals were searched and data reviewed retrospectively between July 2010 and December 2022. Factors contributing to outcomes after EP placement were assessed.

RESULTS

The primary reasons for referral included collapsing/syncopal episodes (n = 36), exercise intolerance (15), and significant bradycardia (46). Third-degree atrioventricular block (39/52 [75%]) was the predominant indication for pacemaker placement, and common reasons for EP placement included previous transvenous pacemaker dislodgment/loss of capture (n = 12) and small body size (10). Intra- and postoperative complications were documented in 11% and 23% of dogs, respectively. Overall, 96% of dogs survived to discharge, and median follow-up time was 462 days (range, 31 to 3,139 days). Presence of coexistent myocardial or valvular disease at the time of EP implantation was associated with a reduced survival. Owners reported decreased clinical signs, increased activity levels, and improved HRQoL.

CLINICAL RELEVANCE

Epicardial pacemaker implantation is a valuable option for dogs requiring artificial cardiac pacing. Complications were common but did not impact the overall outcome. Dogs with a coexisting cardiac pathology had a shorter life expectancy after EP placement, but their HRQoL appeared to be good, with an improvement in clinical signs and increased activity levels.

Authors: Glick Aaren , Jaffey Jared A. , Kreisler Rachael , Hanzlicek Andrew S. , Ringold Randy
Published: June 2024

OBJECTIVE

To evaluate temporal changes in serum C-reactive protein (CRP) and haptoglobin (Hp) concentrations in dogs with pulmonary coccidioidomycosis and assess their utility to detect remission.

METHODS

31 client-owned dogs with newly diagnosed pulmonary coccidioidomycosis from October 2020 to February 2021 were included in a retrospective cohort study that utilized archived serum. Serum was originally obtained at diagnosis and once every 3 months after antifungal administration until either remission or 12 months. Time points were designated as baseline (T0), 3 months (T1), 6 months (T2), 9 months (T3), and 12 months (T4). Serum CRP and Hp were measured at a reference laboratory with ELISA assays.

RESULTS

Median serum CRP and Hp concentrations decreased from T0 (CRP, 56 mg/L; Hp, 716.1 mg/dL) to T1 (CRP, 3.3 mg/L; Hp, 240.5 mg/dL); subsequent decreases were not significant. Eighteen (60%) and 16 (53%) of 30 dogs had normal serum CRP and Hp concentrations at T1, respectively. Absolute serum CRP (AUC, 0.58; 95% CI, 0.45 to 0.72) and Hp (AUC, 0.65; 95% CI, 0.52 to 0.78) were poor detectors of remission. However, the percentage change in Hp from T0 to T1 (AUC, 0.90; 95% CI, 0.74 to 1.0) was an excellent predictor of remission within 12 months.

CONCLUSIONS

Serum CRP and Hp concentrations decrease in the first 3 months of antifungal treatment in dogs with pulmonary coccidioidomycosis, and the percentage change of Hp may help predict dogs that will achieve remission within 12 months of treatment.

CLINICAL RELEVANCE

Serum CRP and Hp may be useful adjunctive biomarkers to monitor treatment response in dogs with pulmonary coccidioidomycosis.

Published: June 2024

Many researchers have differed on the optimum values of Daylighting and Passive Indoor Thermal Comfort (DPITC) determinants in tropical climates. The study is aimed at developing a framework for optimising DPITC in singled-banked office buildings, during the activity period (8 a.m. to 5 p.m.), in the temperate dry climate of Nigeria. It was achieved by evaluating the effects of orientation, window-to-wall ratio (WWR), R-values of external wall insulation material, and shading devices on DPITC. A quantitative research design using an explorative design approach was employed in the study as well as an experimental research strategy through simulation method to optimise DPITC. The study used the Federal Secretariat building of Nigeria as a prototype of a single-banked office building. The Google SketchUp Pro 2022 and OpenStudio 3.3.0 simulation tools were used to evaluate the prototype building from January to December 2023. The data generated was analysed using relevant statistical tools (MANOVA, ANOVA, column charts, graphs, and tables). The findings revealed that the best WWR for daylighting and passive indoor thermal comfort are 20% and 15% respectively, while the compromise value was 20%. It was also noted that the R-value of the external wall insulation material does not affect the daylighting of an office building but affects the passive indoor thermal comfort, where the optimum R-value was of 3.26 m2·K/W. The mathematical model was developed as A= 224.58 − 1254.84 WWR+ 102.87 PF − 4.11R … … .1 where A is orientation, WWR window-to-wall ratio, PF projection factor, and R is the R-value of the external wall materials.

Published: June 2024

The principal objective of this paper was to assess the physical properties and weight or structural implications of some potential green roof growth media compositions practicable for use in the Nigerian built environment. The study carried out an essential selection of material constituents of growth media blends mixed in a 3:1:1 ratio of natural stone-based gravels, soil and compost respectively. Six substrate blends based on later-ite stones, ory and empirical field evaluation methods. The results revealed that the granite-based blend is the heaviest sample with 1,713.30 kg/m3 in its saturated state, while the lightest in weight is the pumice blend with 869.30 kg/m3 which is 50.7% less than the granite blend. The heaviest and the lightest outlined models were subsequently subjected to a weight analysis on a proposed reinforced concrete flat-roofed structure. The results showed that all the extensive green roof samples fall within the IBC stipulated range. The heaviest granite substrate obtained a design load of 0.951 kN/m2, while the lightest pumice blend recorded a design load of 0.576 kN/m2. Hence, it stands to offer an optimum alternative in green roof retrofitting projects for existing flat-roofed buildings. The study, therefore, submits that all samples evaluated involve readily available materials in the studied area and can be used with respect to their characteristic properties as presented in this study. It also serves as a reference point for all stakeholders in the research and building construction industry in Nigeria and beyond.

Published: June 2024

Introduction:

The study aimed to investigate the implementation of Competency-Based Language Teaching assessment and proficiency in English speaking skills.

Methods:

The study adopted a mixed methods approach and descriptive survey design. A random sample of 97 grade four English teachers and 56 grade four students were selected. The study utilized various methods to collect data, including a questionnaire, observation, interview, and oral test. The study employed both quantitative and qualitative data analysis methods.

Results:

The result showed that there was limited implementation of Competency-Based Language Teaching assessment in speaking skills. The findings also showed that the teachers’ awareness of the purpose of the speaking skills assessment in Competency-Based Language Teaching was below average. The study also found that students scored below satisfactory in speaking skills competencies, indicating that they did not achieve the intended level of mastery.

Discussion:

Teachers' awareness of the assessment's aim must be ensured to guarantee the implementation of the Competency-Based Language Teaching assessment. Competency-Based Language Teaching assessment also should ensure the achievement of learners’ speaking competency.

Limitations:

The number of schools selected as the sample was only four for the questionnaire and achievement test.

Conclusions:

The study recommends that teachers implement Competency-Based Language Teaching assessments practically in spoken language instruction, be aware of the purpose of Competency-Based Language Teaching assessments in speaking skills, and promote learners based on the mastery of competency at each level.

This study aims to analyse the phenological dynamics of tree species in response to changes in climatic conditions over the last two climate-normal periods (CLINO 1961−1990 and 1991−2020). We focused on the main climax tree species (Quercus species, Fagus sylvatica L., Abies alba Mill., Picea abies [L.] Karst., and Pinus mugo Turra) dominating eight altitudinal forest vegetation zones (FVZ) and alluvial forests of Western Carpathians and adjacent lowlands in Central Europe. The phenological phases analysed in this study were first leaf (BBCH11) and general leaf colouring (BBCH94) for deciduous species, and the onset of new shoots (BBCH10) for evergreen conifers. The results of partial correlations confirmed that temperature is the main driving factor explaining the shifted onset of phenological phases for the species considered. Furthermore, deciduous species growing in the lower (and warmer) FVZ showed a certain level of drought sensitivity related to the earlier BBCH94. The identified trends in phenology were species-specific and differed between the individual FVZs. The most pronounced shifts toward the earlier BBCH10 and BBCH11 were found in the upper FVZ of the vertical distribution range of species. The presented results will support our understanding of the mechanisms underlying environmental control of tree phenology. This is crucial for predicting how the growing season of trees will be constrained by climate change-induced conditions in individual FVZ.

Research purpose.

The research purpose of this paper was to explore the evaluation of skills by academic staff to improve the quality of the administration process in higher education institutions (HEIs) from two perspectives. Firstly, the authors investigated whether there are statistically significant differences between the genders of academic staff in higher education institutions regarding the evaluation of their skills and competencies. Secondly, the study aimed to determine if there are statistically significant differences in competencies perceived between academic staff of STEM sciences and those with academic experience in other sciences in terms of assessing their professional competencies. The purpose was determined by the impact of self-assessment of professional competencies on the improvement of administrative processes.

Design / Methodology / Approach.

The survey, using the authors` developed questionnaire, was distributed in Ukraine from 2019 to 2023. 374 respondents were surveyed. To test hypotheses, the authors employed the Mann-Whitney U test for gender-related hypotheses and the Kruskal-Wallis test for hypotheses related to the area of scientific and academic activities.

Findings.

Due to the analysis carried out in the present research, the Mann-Whitney non-parametric test showed that there is no statistically significant difference between the gender groups and their professional competencies evaluation, which leads to the rejection of the first hypothesis. The second hypothesis was also rejected, as based on the Kruskal-Wally’s test there is no statistically significant difference between the perception of the professional competencies among the academic staff of STEM and other sciences.

Originality / Value / Practical implications.

Unlike other studies, this research specifically focuses on the differences between the self-assessment-based perceptions by genders and STEM sciences academic staff compared to representatives of other branches of science at HEIs in Ukraine. The practical value is achieved by the research thus ensuring administrative staff with defined competencies and self-assessment criteria. The research findings then will allow us to link competencies to administration processes and offer training and development opportunities based on identified competency gaps. The feedback mechanism might be established based on the research data and these self-assessment results might be incorporated into the performance evaluation processes, thus improving the quality of the educational process and its administration in HEIs. Practical implications are related to the state and period of the research, due to the present war in Ukraine.
Teacher Perceptions on Using Translanguaging for Teaching Second and Foreign Languages in Sri Lanka
Authors: Dassanayake Noel
Published: June 2024

The linguistic landscape of Sri Lanka underwent dramatic transformations owing to the influence of Indic languages and the colonization which resulted in increased language contact and hybridization of local languages. Advancements in digital and commercialization of language learning increased the demand for second and foreign language education. Whether language planning and education have undergone changes in par with the transformations in the linguistic landscape is questionable. Approaches and methodologies of second and foreign language learning in Sri Lanka remain entrenched in hegemonic practices of post-colonial language education. Taking on a convergent parallel design, the present study explored the potentials of incorporating translanguaging into second and foreign language education in Sri Lanka. Teachers of English as a second language and three other foreign languages were selected as the key informants of the study. Recognizing language as a transformative entity from a sociolinguistic stance, the study employed dynamic systems theory to evaluate the significant transformations of the linguistic landscape in Sri Lanka juxtaposed with developments in language studies. The findings have revealed that although the teachers have identified the need for shifting towards inclusive language education that recognizes the significance of learners’ native language repertoire, the language education system is still entrenched in the conservative approaches. Teaching learning material and ideologies attached to second and foreign languages education have become ‘leg irons’ that constrain adaptation into the new language environment. National scale linguistic landscape surveys, transformations in methodologies, localized learning material and long-term language policy and planning initiatives are key requirements for ensuring inclusive, equitable and decolonized language education.
