Being outdoors in a natural environment is thought to be restorative and relaxing (Kaplan & Kaplan, 1989). For people with dementia, nature and outdoor spaces (‘ingericht groen’) can provide a stimulating environment with exposure to light and sensory experiences (Burns et al. 2002; GuissetMartinez et al., 2013) as well as engagement in pleasant activities (Mac-Donald, 2002). It is reported tha...

James Yorke won the 2003 Japan Prize for his work in the field of chaos theory. This book was compiled by four of his best-known collaborators in honor of his 60th birthday and contains papers by various authors on chaos and chaotic attractors. The papers are organized around the topics of “natural” invariant measure and fractal dimension of the associated chaotic attractors. A few of the paper...

We have investigated the threshold of photodetachment of Li− leading to the formation of the residual Li atom in the 2p P state. The excited residual atom was selectively photoionized via an intermediate Rydberg state and the resulting Li ion was detected. A collinear laser-ion beam geometry enabled both high resolution and sensitivity to be attained. We have demonstrated the potential of this ...

Dynamic programming [1] has full sensitivity, but too slow for large scale homology search. FASTA / BLAST type of heuristics [2] trade sensitivity for speed. Can we have both sensitivity and speed? We present the mathematical theory of optimized spaced seeds which allows modern homology search to achieve high sensitivity and high speed simultaneously. The spaced seed methodology is implemented ...

This paper examines the joint hypotheses that firms set optimal levels for CEO incentives, and that firms and CEOs jointly correct deviations from these optimal levels through equity grants and CEO portfolio rebalancing. I investigate two equity-based CEO incentives, pay-forperformance sensitivity and risk-taking incentive. Pay-for-performance sensitivity is defined as the change in CEO wealth ...
