Business Group Affiliation and Environmental Innovation: The Moderating Role of Board Diversity
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines the relationship between business group (BG) affiliation and corporate environmental innovation, with a particular focus on the moderating role of board diversity. Drawing on resource dependence theory (RDT) and agency theory, we argue that although BGs provide affiliated firms with strategic resources, their governance ...

The exterior Dirichlet problem for the homogeneous $k$-Hessian equation
, 2022 We study the exterior Dirichlet problem for the homogeneous $k$-Hessian equation. The prescribed asymptotic behavior at infinity of the solution is zero if $k<\frac{n}{2}$, it is $\log|x|+O(1)$ if $k=\frac{n}{2}$ and it is $|x|^{\frac{2k-n}{n}}+O(1)$ if $k>\frac{n}{2}$.

Chemistry – A European Journal, EarlyView.The integrated experimental‐computational study on the asymmetric activation exerted by isohexides on tropos tetra‐aryl moieties embedded in a chiral macrocyclic architecture resulted in a complete definition of the stereochemical as well as stereodynamic features of the macrocyclic final compounds.

Sharp asymptotic expansions of entire large solutions to a class of k-Hessian equations with weights
Advances in Nonlinear AnalysisIt is well-known that it is a quite interesting topic to study the asymptotic expansions of entire large solutions of nonlinear elliptic equations near infinity. But very little is done.

Nonparametric maximum likelihood estimation of the survival function using current lifetime data
Canadian Journal of Statistics, EarlyView.Abstract An issue when estimating the failure time survival function is how to set up a prevalent cohort study infrastructure to follow subjects after enrollment. This problem can be circumvented through the well‐known Grenander density estimator using current lifetime observations only.

A posteriori error covariances in variational data assimilation [PDF]
, 2009 The problem of variational data assimilation for a nonlinear evolution model is formulated as an optimal control problem to find some unknown parameters of the model.

Gauge-covariant Raychaudhuri dynamics for spin-nondegenerate Lorentz-violating congruences
European Physical Journal C: Particles and FieldsWe investigate the Raychaudhuri dynamics of charged spin-nondegenerate Lorentz–violating particle congruences under minimal electromagnetic coupling. The coupling is introduced through the gauge-covariant momentum $$P_{\mu }=\pi _{\mu }-qA_{\mu }$$ P μ =

Homophily‐adjusted social influence estimation
Canadian Journal of Statistics, EarlyView.Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...

The pluricomplex Green function of the Monge-Ampère equation for $(n-1)$-plurisubharmonic functions and form type $k$-Hessian equations [PDF]
In this paper, we introduce the pluricomplex Green function of the Monge-Amp\`{e}re equation for $(n-1)$-plurisubharmonic functions by solving the Dirichlet problem for the form type Monge-Amp\`{e}re and Hessian equations on a punctured domain.
