Enhancing Emotional Vocabulary In Esl Learners Through Corpus-Based Instruction And Bilingual Scaffolding, Udaya Muthyala, Jyothsna Bethala, Banoth Suresh Jun 2026

Enhancing Emotional Vocabulary In Esl Learners Through Corpus-Based Instruction And Bilingual Scaffolding, Udaya Muthyala, Jyothsna Bethala, Banoth Suresh

Journal of English and Applied Linguistics

This study investigates the efficacy of integrating corpus-based tools and bilingual scaffolding to explicitly instruct emotional vocabulary (EV) among secondary school ESL learners. Despite its criticality for interpersonal communication and identity construction, EV remains marginalized in ELT curricula, a research gap driven by the inherent abstractness of affective lexis and a lack of systematic, data-driven frameworks for its instruction. To address this, a quasi-experimental intervention was conducted with 90 Class VIII students at a government high school in Tadepalli, Andhra Pradesh. The study utilized a mixed-methods approach, leveraging Sketch Engine and AntConc to generate contextualized concordance lines, which were further …

Tumor-Immune Dynamics With Memory And Time Delay: A Fractional-Order Model With Ctla-4 Regulation, Mutaz Mohammad, Mohyeedden Sweidan, Alexander Trounev, Fathalla Rihan Jun 2026

Tumor-Immune Dynamics With Memory And Time Delay: A Fractional-Order Model With Ctla-4 Regulation, Mutaz Mohammad, Mohyeedden Sweidan, Alexander Trounev, Fathalla Rihan

All Works

This study develops a fractional-order tumor-immune interaction model incorporating Caputo memory effects, delayed immune activation, and CTLA-4 checkpoint regulation. The model describes the coupled dynamics of tumor cells, CD4^+ T cells, IFN-γ, and CTLA-4, and extends classical integer-order tumor-immune models by accounting for hereditary immune responses and biologically motivated latency effects. Theoretical properties, including positivity, boundedness, equilibrium structure, and fractional-order stability, are examined to establish the biological and mathematical consistency of the model. The delayed fractional system is then investigated computationally by comparing several numerical methods, including finite difference discretization, Daubechies wavelet collocation, Euler wavelet collocation, and a predictor-corrector scheme. …

Monte Carlo Analysis Of Dose Distribution In Tumour And Adjacent Healthy Tissues During 192Ir Hdr Brachytherapy In The Presence Of Gold Nanoparticles, Damian P. Tippe, Innocent J. Lugendo Jun 2026

Monte Carlo Analysis Of Dose Distribution In Tumour And Adjacent Healthy Tissues During 192Ir Hdr Brachytherapy In The Presence Of Gold Nanoparticles, Damian P. Tippe, Innocent J. Lugendo

Tanzania Journal of Science

High dose rate (HDR) brachytherapy using 192Ir is an effective modality for cancer treatment; however, its therapeutic efficiency is often constrained by unintended radiation exposure to healthy tissues surrounding the tumour. Fortunately, the incorporation of high atomic number (Z) nanoparticles as radiosensitizers has emerged as a promising strategy to enhance tumour dose while sparing adjacent normal tissues. In this study, the dose distribution in tumour and nearby healthy tissues during 192Ir HDR brachytherapy was investigated in the presence of gold (Au) nanoparticles using Monte Carlo simulations based on the Geant4 toolkit. Radial dose distributions and anisotropy characteristics were analysed …

Linear Programming Model For Optimal Crop Allocation Under Varying Land Sizes In Pawaga, Tanzania, Mustapha Abbas Kiswanya, Seleman Ismail, Saul Mpeshe Jun 2026

Linear Programming Model For Optimal Crop Allocation Under Varying Land Sizes In Pawaga, Tanzania, Mustapha Abbas Kiswanya, Seleman Ismail, Saul Mpeshe

Tanzania Journal of Science

Farmers often rely on intuition when selecting crops, which can lead to suboptimal profits. In this study, we examine the optimal annual crop allocation under varying land sizes for farmers in Pawaga, Iringa District, Tanzania. A parametric linear programming (LP) model is developed to determine crop allocation combinations that maximise profit subject to land, labour, and capital constraints. Unlike conventional approaches that require separate models for different farm sizes, the proposed model accommodates land holdings ranging from 1 to 9 acres and integrates nine crop types within a single framework. Data were collected over three (3) agricultural seasons from extension …

Joint Channel And Phase Noise Estimation For Mmwave Ofdm Systems Using Adaptive Kalman Filtering, Kwame Salum Ibwe Jun 2026

Joint Channel And Phase Noise Estimation For Mmwave Ofdm Systems Using Adaptive Kalman Filtering, Kwame Salum Ibwe

Tanzania Journal of Science

This manuscript presents a joint channel and phase-noise estimation framework for millimeter-wave (mmWave) OFDM systems based on an adaptive extended Kalman filter (EKF). The proposed method formulates a unified state-space model that simultaneously tracks time-varying multipath channels and oscillator phase noise, a critical impairment in 5G NR frequency range 2 (FR2) and emerging 6G transceivers. An innovation-based covariance adaptation mechanism is introduced to enhance estimation accuracy while maintaining computational efficiency. Simulation results demonstrate that the proposed approach achieves up to a 5 dB SNR gain at a target BER of 10⁻³, maintains NMSE below 10⁻³ for linewidths up to 200 …

From Tragedy To Liberation: The Tragic Mulatta And Abolition Democracy At The Intersection Of Race And Gender In The Quadroons And The Octoroon, Maram Mohammed Mahmoud Samman Jun 2026

From Tragedy To Liberation: The Tragic Mulatta And Abolition Democracy At The Intersection Of Race And Gender In The Quadroons And The Octoroon, Maram Mohammed Mahmoud Samman

University of Tabuk Journal for Humanities and Social Sciences

This essay explores the figure of the tragic mulatta in Lydia Maria Child’s The Quadroons and Dion Boucicault’s The Octoroon, analyzing how mixed-race female characters critique the racial and gender hierarchies of 19th-century America. Using an intersectional lens, it examines how race, gender, and class shape the identities and tragic fates of Xarifa and Zoe—women who were socially excluded from both Black and White communities. Drawing on W.E.B. Du Bois’s concept of double consciousness and the framework of Abolition Democracy, the essay argues that the tragic mulatta is not merely a narrative trope but a site of political tension and …

Modelling Of Dust Devil Flow Dynamics: Effects Of The Sharpness Parameter On Velocity And Pressure, Deepanshu Kumar, Hossein Jafari Jun 2026

Modelling Of Dust Devil Flow Dynamics: Effects Of The Sharpness Parameter On Velocity And Pressure, Deepanshu Kumar, Hossein Jafari

Mathematical Modelling and Numerical Simulation with Applications

This work discusses the development of a straightforward model of dust devils, demonstrating a method for estimating wind speed and pressure. The current model incorporates momentum equations and the mass conservation equation for steady, axisymmetric, inviscid, and incompressible flow. In this model, the radial velocity is first considered, which is restricted in both the radial and axial directions. The sharpness parameter is also incorporated into the radial velocity formulation, as described by Vatistas model. Using the radial velocity as a foundation, we derive the azimuthal and axial velocities. The study further evaluates the pressure. Notably, for large values of the …

Dynamical Behavior, Extinction And Persistence In A Stochastic Delayed Two-Strain Epidemic Model With A Generalized Crowley-Martin Incidence Rate, Amina Allali, Dounia Bentaleb, Saida Amine Jun 2026

Dynamical Behavior, Extinction And Persistence In A Stochastic Delayed Two-Strain Epidemic Model With A Generalized Crowley-Martin Incidence Rate, Amina Allali, Dounia Bentaleb, Saida Amine

Mathematical Modelling and Numerical Simulation with Applications

This paper develops and analyzes a novel delayed stochastic SIR epidemic model with two interacting strains and general incidence functions. By establishing the existence and uniqueness of a positive global solution, the well-posedness of the model under stochastic perturbations is ensured. Extinction occurs when the stochastic reproduction number falls below unity, as demonstrated through Itô calculus and martingale convergence theorems, while persistence is guaranteed under the Crowley–Martin incidence when it exceeds one. Numerical experiments based on the Positive Preserving Truncated Euler–Maruyama (PPTEM) scheme confirm the analytical predictions and highlight the influence of time delay and noise intensity on the long-term …

Entrenchment And Expansion: How Political Dynasties Affect Poverty Within And Between Philippine Provinces, Jurel K. Yap Jun 2026

Entrenchment And Expansion: How Political Dynasties Affect Poverty Within And Between Philippine Provinces, Jurel K. Yap

Asia-Pacific Social Science Review

The persistence of poverty in the Philippines is linked in the literature to the prevalence of political dynasties, yet the precise mechanisms of this relationship remain underexplored. This study sought to disentangle two distinct phenomena: the effect of long-term dynastic entrenchment (structural, between-province differences) from that of dynamic dynastic expansion (changes within a province over time). To do so, this paper employed a within-between panel data model on a unique dataset covering 80 provinces from 2004 to 2021, with the Political Concentration Index (Political HHI) as the primary measure of dynastic power. The results showed that while dynastic entrenchment and …

A Case Study Of Sport And Racism In Australia: A Qualitative Document Analysis, Vegneskumar Maniam, Kristy O’Neill

Asia-Pacific Social Science Review

Australia is well known as a ‘sporting nation’ with outstanding elite sporting achievements and grassroots-level sports participation. The reality for Australia’s First Nations people and those from Culturally and Linguistically Diverse (CALD) backgrounds, however, tends to differ from the mainstream Australian population. One of the contributing factors being argued within this paper is the prevalence of historical and contemporary racism in Australian sport. This study focuses on four of Australia’s most popular community-participation sports, including Australian Rules Football (ARF), Cricket, Netball, and Swimming. Using a Qualitative Document Analysis method, this research investigates both primary and secondary sources for instances of …

Institutionalizing Public Consultation In Thai Health Legislation: Lessons From Ria And Pls Practices, Stithorn Thananithichot, Wichuda Satidporn, Chompunoot Tangthavorn

Asia-Pacific Social Science Review

Public consultation is increasingly recognized as a cornerstone of democratic governance, yet its institutionalization in middle-income democracies such as Thailand remains uneven. Although the 2017 Constitution and the 2019 Act on Legislative Drafting and Legal Evaluation mandate participatory processes through Regulatory Impact Assessment (RIA) and Post-Legislative Scrutiny (PLS), implementation has often remained procedural rather than substantive. This study examines how consultation practices operate within Thailand’s public health legislation, a policy domain characterized by significant distributive and ethical implications. Using a qualitative comparative case study design, the research analyzes three legislative processes: the National Health Security Act B.E. 2545 (2002), the …
