Ideals and Green's relations in ordered semigroups

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Exactly as in semigroups, Green's relations play an important role in the theory of ordered semigroups—especially for decompositions of such semigroups.

Environmental Supply Chain Regulations in a Changing Market Environment: Exploring the EU's Regulatory Power in the Cocoa Sector in Ghana

open access: yesJCMS: Journal of Common Market Studies, Volume 64, Issue 2, Page 811-834, March 2026.
Abstract The article explores the European Union's (EU) regulatory power through supply chain initiatives, in the context of shifting market dynamics towards China and Association of Southeast Asian Nations (ASEAN). Focusing on the EU Regulation on Deforestation‐free products (EUDR) and the cocoa sector in Ghana as a most likely case study, the article

Toward Psychometric Learning Analytics: Augmenting the Urnings Algorithm with Response Times

open access: yesJournal of Educational Measurement, Volume 63, Issue 1, Spring 2026.
Abstract Adaptive learning systems (ALS) aim to tailor the educational material to match the student's needs, ultimately improving the learning outcomes. An ALS dynamically adjust the level of practice based on the student's ability; therefore, obtaining accurate ability estimates is crucial.

WDVV‐based recursion for open Gromov–Witten invariants

open access: yesJournal of Topology, Volume 19, Issue 1, March 2026.
Abstract We give a computability result for open Gromov–Witten invariants based on open Witten–Dijkgraaf–Verlinde–Verlinde (WDVV) equations. This is analogous to the result of Kontsevich–Manin for closed Gromov–Witten invariants. For greater generality, we base the argument on a formal object, the Frobenius superpotential, that generalizes several ...

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...
