A goodness‐of‐fit test for regression models with discrete outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Self‐Similar Blowup for the Cubic Schrödinger Equation

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We give a rigorous proof for the existence of a finite‐energy, self‐similar solution to the focusing cubic Schrödinger equation in three spatial dimensions. The proof is computer‐assisted and relies on a fixed point argument that shows the existence of a solution in the vicinity of a numerically constructed approximation.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Public Sustainability: Thematic Mapping, Theoretical Approaches and Emerging Lines of Action

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The paucity of research analysing thematic persistence in public sustainability limits our understanding of how this field of research evolves and reconfigures itself. The present paper addresses this gap through a longitudinal bibliometric analysis of 692 publications processed with SciMAT. The methodology combines co‐word analysis, strategic

Diversity and Inclusion Standards: Exploring Drivers and Determinants of Adoption of ISO 30415:2021 and UNI/PdR 125:2022 in Italian SMEs

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the adoption of Diversity and Inclusion (D&I) standards among Italian small and medium‐sized enterprises (SMEs), focusing on the international guideline ISO 30415:2021 and the national certification UNI/PdR 125:2022. Using survey data from 866 SMEs across six manufacturing and service industries and applying descriptive
