Combatting Skepticism Towards HR

[Excerpt] When assessing the essentiality of HR within a firm, one must first ask what is meant by the word “essential” within a business context. The trickiness here, however, is that such a definition is highly contingent on the type and size of a particular firm. If one defines “essential” as “indispensable,” then HR is almost certainly not essential in very small firms. In such instances, the work of HR can be done by other managers and the owners themselves. On the other hand, if one defines “essential” as “adding considerable value,” then innovative human resource policies can create a competitive advantage even in the smallest of firms. Instead of relying on a single definition of essentiality, this essay will focus on the reasons why human resources practices are often called into question in the first place. Furthermore, I will propose recommendations on how to combat skepticism toward HR

Lecture Notes on Gradient Flows and Optimal Transport

We present a short overview on the strongest variational formulation for gradient flows of geodesically $\lambda$-convex functionals in metric spaces, with applications to diffusion equations in Wasserstein spaces of probability measures. These notes are based on a series of lectures given by the second author for the Summer School "Optimal transportation: Theory and applications" in Grenoble during the week of June 22-26, 2009

Dimensional Reduction and Approximation of Measures and Weakly Differentiable Homeomorphisms

This thesis is devoted to the study of two different problems: the properties of the disintegration of the Lebesgue measure on the faces of a convex function and the existence of smooth approximations of bi-Lipschitz orientation-preserving homeomorphisms in the plane
