Business Strategy and the Environment, EarlyView.ABSTRACT Firms increasingly face political and societal pressures to pursue green strategies and sustainable innovation amid escalating climate change disruptions. Drawing upon contingency theory, institutional theory, and the natural resource‐based view, this article examines external (stakeholder pressures) and internal (environmental culture ...

, 2017 Motivated by the close relation between Aubry-Mather theory and minimal geodesies on a 2-torus we study the existence and properties of minimal geodesics in compact Riemannian manifolds of dimension ≥3.

TRIANGLES, SQUARES AND GEODESICS
International Journal of Algebra and Computation, 2012 In the early 1990s Steve Gersten and Hamish Short proved that compact nonpositively curved triangle complexes have biautomatic fundamental groups and that compact nonpositively curved square complexes have biautomatic fundamental groups. In this paper we report on the extent to which results such as these extend to nonpositively curved complexes built

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates
Chemistry – A European Journal, EarlyView.Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium

Metrics with homogeneous geodesics on flag manifolds [PDF]
, 2002 summary:A geodesic of a homogeneous Riemannian manifold $(M=G/K, g)$ is called homogeneous if it is an orbit of an one-parameter subgroup of $G$. In the case when $M=G/H$ is a naturally reductive space, that is the $G$-invariant metric $g$ is defined by ...

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

Hypersurface Constrained Elasticae in Lorentzian Space Forms
Advances in Mathematical Physics, 2015 We study geodesics in hypersurfaces of a Lorentzian space form M1n+1(c), which are critical curves of the M1n+1(c)-bending energy functional, for variations constrained to lie on the hypersurface. We characterize critical geodesics showing that they live

Deep Underground Science and Engineering, EarlyView.Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...

International Journal of Eating Disorders, EarlyView.ABSTRACT Objective Early adolescence is characterized by the onset of mental health problems, including eating pathology (e.g., body image concerns, restrictive eating). Inhibitory control (IC) and reward sensitivity (RS) are two key traits that have been implicated in the development of eating problems.
