Images of Coordination: How Implementing Organizations Perceive Coordination Arrangements [PDF]
Public Administration Review, 2019 AbstractA crucial challenge for the coordination of horizontal policy programs—those designed to tackle crosscutting issues—is how to motivate government organizations to contribute to such programs. Hence, it is crucial to study how practitioners in implementing organizations view and appreciate the coordination of such programs.

Nonnegative Local Coordinate Factorization for Image Representation [PDF]
IEEE Transactions on Image Processing, 2013 Recently, nonnegative matrix factorization (NMF) has become increasingly popular for feature extraction in computer vision and pattern recognition. NMF seeks two nonnegative matrices whose product can best approximate the original matrix. The nonnegativity constraints lead to sparse parts-based representations that can be more robust than nonsparse ...
