Moving Aggregate Modified Autoregressive Copula‐Based Time Series Models (MAGMAR‐Copulas)
Journal of Time Series Analysis, EarlyView.ABSTRACT Copula‐based time series models can model univariate and stationary time series in a flexible way by decomposing the joint distribution of consecutive observations into a copula and the stationary distribution. Implicitly, this approach assumes a finite Markov order. In reality, a time series may not follow the Markov property.

Never, Ever Getting Started: On Prospect Theory Without Commitment
Mathematical Finance, EarlyView.ABSTRACT Prospect theory is arguably the most prominent alternative to expected utility theory. We study the investment or gambling behavior of a prospect theory decision maker who is aware of his time‐inconsistency but lacks commitment. For the empirically relevant prospect theory specifications, we obtain the extreme prediction that such a decision ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism
Noûs, EarlyView.ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.

Exploring 2D Geometric Shape Classification Using AI‐Driven Feature Tables in Mathematics
School Science and Mathematics, EarlyView.ABSTRACT This study explored the effectiveness of an AI‐integrated instructional task designed to enhance preservice teachers' understanding of the features and hierarchical relationships of 2D geometric shapes. Originally developed and tested in online K‐12 professional development settings, this intervention was adapted for in‐person preservice ...

Signed Projective Cubes, a Homomorphism Point of View
Journal of Graph Theory, Volume 113, Issue 1, Page 38-56, September 2026.ABSTRACT The (signed) projective cubes, as a special class of graphs closely related to the hypercubes, are on the crossroad of geometry, algebra, discrete mathematics and linear algebra. Defined as Cayley graphs on binary groups, they represent basic linear dependencies.

Nonstandard Analysis Applied to Advanced Undergraduate Mathematics - Infinitesimal Modeling
, 2003 This is a Research and Instructional Development Project from the U. S. Naval Academy. In this monograph, the basic methods of nonstandard analysis for n-dimensional Euclidean spaces are presented. Specific rules are deveoped and these methods and rules are applied to rigorous integral and differential modeling.

TESOL Journal, Volume 17, Issue 3, September 2026.ABSTRACT This article presents findings from a workshop in an anti‐racist teacher education course. Drawing from raciolinguistic ideologies, anti‐Black linguistic racism, and Extraordinary Pedagogies rooted in anti‐bigotry praxes, the workshop engaged white teacher candidates (TCs) to interrogate standard academic English as a racialized norm that ...
