ABSTRACT This study pursues a dual objective. First, it investigates the unconditional impact of anti‐globalization on structural transformation in Africa. Second, it explores how environmental degradation interacts with anti‐globalization to influence structural transformation. The analysis focuses on 52 African countries over the period 2005–2023. To

Real Time Detection of Structural Breaks in GARCH Models [PDF]
A sequential Monte Carlo method for estimating GARCH models subject to an unknown number of structural breaks is proposed. Particle filtering techniques allow for fast and efficient updates of posterior quantities and forecasts in real time.

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

A multivariate generalized independent factor GARCH model with an application to financial stock returns [PDF]
We propose a new multivariate factor GARCH model, the GICA-GARCH model , where the data are assumed to be generated by a set of independent components (ICs).

Organotitanyl “TiCp” Fragment Capping the Bowl‐Shaped Unit in the Ternary Anion [(Cp)Ti(Sn3Bi3)]2−
A novel ternary anion, [(η5‐Cp)Ti(Sn3Bi3‐κ3)]2− composed of a cyclopentadienyl titanium fragment coordinated by a Sn3Bi3 bowl‐shaped cluster unit, is reproted. Unlike homoatomic nine‐atom clusters of heavier tetrel elements, which retain their identity upon dissolution, intermetalloid clusters are not formed directly from ternary alkali‐metal alloys in

ABSTRACT This study examines volatility interconnectedness among selected agricultural commodities and precious/industrial metals, together with oil price uncertainty and global supply chain pressure, over the period January 1998 to June 2024 using a Quantile‐on‐Quantile connectedness framework.

Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.
