Assessing the awareness of media literacy and fake news among the youth during the national general election

Purpose At present, most people use social media. Social media can be considered a double-edged sword; one is a rapid way for information dissemination at low cost, and the other is the widespread spread of misinformation or fake news. This study aims to assess the media literacy...

A systematic review of system dynamics and agent-based models: Mathematical modelling for health systems research

Background: Mathematical modelling has emerged as a powerful approach for analysing complex healthcare systems, which exhibit nonlinear interactions, feedback loops, and adaptive behaviours. Among available techniques, System Dynamics Modelling (SDM) and Agent-Based Modelling (AB...

An Exact Penalty Matrix for Cubic Smoothing Splines on Arbitary Knot Vectors

These notes derive the penalty matrix Ω of a cubic smoothing spline from first principles, for an arbitrary knot vector. Starting from the definition of the B-spline basis, we express differentiation as a matrix, integrate the squared second derivative in closed form, and arrive...

Signatures of rapid trajectory control during finger and arm movements

Normative goal-directed hand and finger movements often follow invariant kinematics, characterized by approximate straight-line trajectories. A fundamental unresolved issue is whether movement trajectories are planned or whether they are a consequence of trajectory-free online co...

Effect of THz electric field on 5CB in the presence of acetonitrile and acetone and its dynamical behaviour in these polar solvents: a DFT and MD simulation study

The electro-optical, NLO, electronic and global reactivity descriptors of 5CB LC molecule have been investigated under the influence of external terahertz (THz) electric field in different solvent environments such as acetonitrile and acetone using DFT-based LC-BLYP/6-311+G(d,p)...

An Alternative Well-being Paradigm: Resistance, Radical Democracy and the Flower of Transformation

This paper examines the intersecting nature of climate and ecological crises across the globe, situating them within wider patterns of inequality, alienation, conflict and dispossession. It critiques the dominant solutions based on technology and market strategies, arguing that r...

The COM Essay Assessor

Providing timely and actionable feedback on student writing is a known challenge in large English as a Second Language (ESL) classrooms, where instructor workload often limits the depth and consistency of feedback. This article presents the development and calibration of the COM...
