Floor- or Ceiling-Sliding for Chemically Active, Gyrotactic, Sedimenting Janus Particles

Meaningful use: Floor or ceiling?

BACKGROUND In 2011, federal incentive payments for meaningful use of electronic health records (EHRs) began. This study evaluates the impact of the program on hospitals and EHR vendors, identifying how it affects EHR planning and development. Specifically, it assesses whether vendors and Chief Information Officers (CIOs) are viewing the meaningful use requirements as a floor - the minimally acc...

Gender Wage Discrimination in India: Glass Ceiling or Sticky Floor?

Traditional analysis of gender wage gaps has largely focused on average gaps between men and women, and mean wage decompositions such as the Blinder-Oaxaca (1973) decomposition method. To answer the question of whether there is a " glass ceiling " or a " sticky floor " , i.e. whether wage gaps are higher at the upper or lower ends of the wage distribution, this paper examines the wage gaps acro...

Collective surfing of chemically active particles.

We study theoretically the collective dynamics of immotile particles bound to a 2D surface atop a 3D fluid layer. These particles are chemically active and produce a chemical concentration field that creates surface-tension gradients along the surface. The resultant Marangoni stresses create flows that carry the particles, possibly concentrating them. For a 3D diffusion-dominated concentration ...

Proposed analyses of floor and ceiling effects.

The Vector Floor and Ceiling Model¤

This paper motivates and develops a nonlinear extension of the Vector Autoregressive model which we call the Vector Floor and Ceiling model. Bayesian and classical methods for estimation and testing are developed and compared in the context of an application involving U.S. macroeconomic data. In terms of statistical signi ̄cance both classical and Bayesian methods indicate that the (Gaussian) li...
