A positive association between intelligence (IQ) and height has been reported previously. It is generally assumed that this association reflects the effect of childhood environment on IQ, but there is still little research supporting directly this hypothesis. We studied the association between height and IQ in 209 Dutch twin pairs at the ages of 5, 7, 10 and 12 years, 208 twin pairs at 16 and 1...

Though longleaf pine (Pinus palustris Mill.) forests have been primarily managed with even-aged methods, interest is increasing in uneven-aged systems, as a means of achieving a wider range of stewardship goals. Selection silviculture has been practiced on a limited scale in longleaf pine, but difficulty with using traditional approaches and absence of an evaluation across a range of site types...

Abstract Inventory data were available from 96 plots of even-aged, monoculture, tall-open forests Eucalyptus pilularis Smith, aged 2–63 years, growing in sub-tropical regions along the east coast Australia. A model was developed relating maximum possible stem basal area growth rate individual trees to their area. For any tree size, this increased as site productivity increased. However, size at...

Plots in an unmanaged loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stand that had been cutover I5 yrpreviously were established to representfive stocking levels: 10, 20, 30, 40, and 50%. The stand was on a good site (site indexLob = 90 ft at 50 yr) and had uneven-aged character. Two competition control treatments (none and individual tree release using herbicide) were also assigne...

abstract background: administration of quality care in the aged people requires having a positive attitude toward them. numerous factors including nurses’ personality characteristics may play a role in their attitude toward the aged people. therefore, the present study investigated the association between nurses’ personality characteristics and their attitude toward the aged people. materials a...
