Height–diameter relationships based on stand characteristics (trees/ha, basal area, and dominant stand height) were investigated for balsam fir, balsam poplar, black spruce, jack pine, red pine, trembling aspen, white birch, and white spruce using data from permanent growth study plots in northern Ontario, Canada. Approximately half the data were used to estimate model parameters with the rest ...

Phenotypic differences in analgesic sensitivity to codeine (3-methoxymorphine) results from polymorphisms in cytochrome P450-2D6, which catalyzes O-demethylation of codeine to morphine. However, O-demethylation reportedly is not required for analgesic activity of the 7,8-saturated codeine congeners dihydrocodeine, hydrocodone, and oxycodone. This study determined the potency and efficacy of the...

Evidence indicates that taller workers earn more, particularly in lower income settings. It is possible that stature is a marker of strength which is rewarded in the labor market, or that height is a proxy for other dimensions of health and human capital including cognition, early-life investments, and other family background characteristics. As such, height may be an informative signal of work...

The aim of this study was to evaluate the association between size at birth (birthweight and birth length) and height in early adolescence in a prospective birth cohort study in Pelotas, Rio Grande do Sul, Brazil. Interviews were carried out in 1993, including measurements of birthweight and length, and in 2004-2005, including measurements of weight and height. This analysis includes 4,452 indi...

Ponderal and linear growth of children has been widely studied; however, epidemiologic evidence of a relationship between the two is inconsistent. Child undernutrition in the form of low height for age and low weight for height continues to burden the developing world. A downward shift in the distribution of height for age in the first 2 y of life is commonly observed in many developing countri...

This paper analyzes whether taller workers earn more then their shorter counterparts. Using GSOEP data from 1991 to 2002, earnings functions are estimated separately for male and female workers in both West and East German regions. The Hausman-Taylor IV estimator ist applied to account for unobservable heterogeneity including also timeinvariant indicators. The results do not suggest for an effe...

The Slave craton in northern Canada is one of the world's smallest Archean cratons (surface exposure of 300,000 km), but makes up for this diminutive stature with excellent exposure and by hosting the oldest dated rocks on Earth (4.03 Ga, Stern and Bleeker 1998). It records continental accretion processes, albeit cryptically, and potentially offers the best opportunity worldwide to address the ...

We assessed whether maternal height was associated with gestational age in a cohort of 294 children born at term. Increasing maternal height was associated with longer pregnancy duration (p = 0.002). Stratified analyses showed that the main effect on pregnancy length appears to occur among shorter mothers (<165 cm tall), whose pregnancies were ∼0.6 and ∼0.7 weeks shorter than pregnancies of mot...
