This research aims at studying health capital depreciation of senior citizens and their corresponding medical care demand. Qualitative response models are constructed, followed by empirical studies. Data is collected from inpatients of Center for Geriatrics and Gerontology at Taichung Veterans General Hospital from 2008 to 2012. All test subjects are under comprehensive geriatric assessment to characterize...
A matrix growth model with constant parameters has been modified, by making survivor growth and mortality of trees functions of stand basal area. The functions, estimated from re-measured plots in Wisconsin maple-birch forests, showed that basal area affected mostly the growth of small trees. However, even when the effects were statistically significant, they were small. Fifteen-year forecasts with...
A density-dependent matrix model of stand growth is presented. The model was calibrated with re-measured plots in the northern hardwood forests in Wisconsin. Trees were divided into shade-tolerant, intermediate, and shade-intolerant species in twelve diameter classes. Model predictions were tested against post-sample observations for short-term (15-year) and long-term (steady-state) accuracy. ...
