South Africa's Inflation: Monetary or Fiscal

South African Journal of Economics, Volume 94, Issue 4, December 2026.
ABSTRACT Conventional macroeconomics has viewed inflation as a monetary phenomenon through the quantity theory of money. Ever‐increasing sovereign debt globally has caused concern amongst economists. These concerns follow not from the ability of governments to repay their debt, but rather the impact of sizeable debt portfolios on price levels.

Human or GenAI Support? Conditions Impacting Students' Strategy Choices in an Essay Revision Task

Journal of Computer Assisted Learning, Volume 42, Issue 5, October 2026.
ABSTRACT Background Students often struggle to effectively self‐regulate their learning strategies during writing tasks and typically require external support from teachers, peers or AI tools to overcome these challenges. While emerging research explores how generative AI can dialogically interact with students to support the writing process, little is

Integrating Acoustic Telemetry and Stable Isotope Data Reveals Overlap in Resource Use by Large‐Bodied Fishes in a Temperate Lake

Ecology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Temperate lake ecosystems undergo seasonal shifts that disproportionately alter the availability of suitable habitat for fishes of different thermal guilds. While many studies have investigated fish habitat use patterns, few have estimated the degree to which fish species overlap in space across seasons from a three‐dimensional perspective ...

Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

Advanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Forecasting Volatility of Commodity, Currency, and Stock Markets: Evidence From Markov‐Switching Multifractal Models

Journal of Forecasting, Volume 45, Issue 6, Page 2905-2941, September 2026.
ABSTRACT This paper adopts a bivariate Markov‐switching multifractal (BMSM) model to reexamine comovement in SV between commodity, foreign exchange (FX), and stock markets. After the 2007–2008 global financial crisis understanding volatility linkages and the correlation structure between these markets becomes very important for risk analysts, portfolio

Nowcasting World Trade With Machine Learning: A Three‐Step Approach

Journal of Forecasting, Volume 45, Issue 6, Page 2954-2968, September 2026.
ABSTRACT We nowcast world trade using machine learning, distinguishing between tree‐based methods (random forest and gradient boosting) and their linear‐regression‐based counterparts (macroeconomic random forest and gradient boosting—linear). While much less used in the literature, the latter are found to outperform not only the tree‐based techniques ...

Develop a novel non‐coplanar trajectory optimization algorithm for an efficient 4pi spot‐scanning proton Arc (SPArc‐4pi) treatment delivery

Medical Physics, Volume 53, Issue 9, September 2026.
Abstract Background The degree of freedom has been recognized as a key factor in particle beam therapy, such as improving the dose conformity and linear energy transfer distributions. Therefore, proton arc therapy has drawn significant interest in the Society of Radiation Oncology as a potentially efficient and optimal treatment option for cancer ...
