Risk Transmission and Co‐Movements Between Financial Markets and Commodity Markets in the COVID‐19 Period

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines risk transmission and co‐movements between financial markets (G7 countries and China) and commodity markets (gold and oil) during the COVID‐19 crisis. Daily closing prices for major equity indices (CAC40, CSI300, DAX30, FTSE100, MIB, NIKKEI, TSX and S&P500) and futures prices for gold, brent and WTI were analysed using DCC ...

Revisiting the Nexus Between Trade Liberalisation and Income Inequality: The Case of Sub‐Saharan African Countries

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper examines the impact of trade liberalisation on income inequality across 24 Sub‐Saharan African (SSA) countries from 2000 to 2020. Using IV‐Tobit and 2SLS models, we consistently find that greater trade openness significantly exacerbates inequality in the region. Critically, we document an inverted U‐shaped relationship between trade

Translating Riedl: The Circulation and Operationalisation of Evolutionary Ideas

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Rupert Riedl's Order in Living Organisms proposed a systems theory of evolution decades before the concepts it pioneered—homology, burden, the imitative epigenotype—reached the agenda of evolutionary biology. This paper reconstructs the lineages that operationalized his insights across several fields and explores the internal and external reasons for ...

Workplace Allyship: An Integrative Review and Agenda for Future Research

Journal of Organizational Behavior, EarlyView.
ABSTRACT Workplace allyship has emerged as a key construct in the literature on diversity, equity, and inclusion. Although research on workplace allyship has expanded rapidly in recent years, advancement in this research stream is limited by conceptual ambiguity and fragmentation across numerous perspectives.

Generalized scenarios of transition to chaos in ideal dynamic systems

Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï
The implementation of a new scenario of transition to chaos in the classical Lorenz system has been discovered. Signs of the presence of an implementation of the generalized intermittency scenario for dynamic systems are described.

Global Synchronization Design for New Hyperchaotic System

Journal of Measurement Science and Instrumentation, 2010
This paper investigates the synchronization and circuit implementation of a new hyperchaotic Lorenz system.This system is generated by controlling a generalized Lorenz system to hyperchaotic by introducing a linear state feedback controller to its second

Abduction and adduction malpositioned lateral radiographs cannot be used for proper assessment of the posterior tibial slope

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare medial posterior tibial slope (mPTS) measurements on abduction/adduction malpositioned versus properly positioned lateral knee radiographs within the same patients. We hypothesized that malpositioning would significantly alter mPTS values and potentially change surgical classification at the commonly used 12° threshold for ...

Posterior tibial slope measurement on lateral radiographs shows increased variability, reduced repeatability and risk of misclassification in osteoarthritic versus nonosteoarthritic knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The primary aim was to compare the variability and repeatability of medial posterior tibial slope (MPTS) measurements on lateral knee radiographs between osteoarthritic (OA) and non‐OA knees, and the secondary aim was to assess their implications for clinical classification.
