We present work to develop a wireless wearable sensor system for monitoring patients with Parkinson’s disease (PD) in their homes. For monitoring outside the laboratory, a wearable system must not only record data, but also efficiently process data on-board. This manuscript details the analysis of data collected using tethered wearable sensors. Optimal window length for feature extraction and f...

A field-usable sleepiness tester could reduce sleepiness related accidents. 15 subjects' postural steadiness was measured with a Nintendo(®) Wii Fit balance board every hour for 24 h. Body sway was quantified with complexity index, CI, and the correlation between CI and alertness predicted by a three-process model of sleepiness was calculated. The CI group average was 8.9 ± 1.3 for alert and 7....

We also found that while better perform...

The valuable cotton seed products have been used elsewh...

This study examines the association between board structure and corporate performance, where performance is defined as the value added (VA) efficiency of the firm’s physical and intellectual resources rather than the more commonly used financial terms or profitability ratios. It is argued that the inclusion of intellectual elements into the measurement provides a long-term measurement of corpor...

The introduction of PowerPoint presentation software has generated a paradigm shift in the delivery of lectures. PowerPoint has now almost entirely replaced chalkboard or whiteboard teaching at the undergraduate and graduate levels. This study investigated whether undergraduate biology students preferred to have lectures delivered by PowerPoint or written on the board as well as the reasons beh...

a r t i c l e i n f o Drawing on the behavioral agency perspective and entrepreneurship literature, we examine the impact of board configuration at the time of an IPO on top management team (TMT) firm-specific human capital, and firm performance in young IPO firms. The results show that the ratio of outside directors at the time of an IPO has a positive relationship with the attrition of TMT fi...
