A US national sample of 2947 future teachers, 457 current teachers, and 1219 education faculty members was asked to rate the importance of various suggestions for improving the professional status of teaching. The results indicated that future teachers differed from current teachers and education professors. The results also suggested that all these groups rated increasing extrinsic and intrins...

We have isolated a cDNA encoding the 31-kDa subunit of the bovine kidney vacuolar H+-ATPase. The composite sequence contains 1219 base pairs, which includes the entire 678-base-pair coding region. A lysine-rich sequence previously found in the Na+, K+-ATPase alpha subunit and the H+,K+-ATPase was identified in the 31-kDa subunit. An RNA blot and an immunoblot demonstrated variable 31-kDa subuni...

A mutation affording low levels of erythromycin resistance has been obtained by in vitro hydroxylamine mutagenesis of a cloned ribosomal RNA operon from Escherichia coli. The site of the mutational event responsible for antibiotic resistance was localized to the gene region encoding domain II of 23S rRNA by replacement of restriction fragments in the wild-type plasmid by corresponding fragments...

Invasive alien species cause significant impacts in agriculture, forestry and the environment, with worldwide economic losses estimated at US $ 1.4 trillion annually, or roughly 5% of the current global economy (Pimentel et al., 2001) and likely to increase in the near future (Perrings et al., 2005; Westphal et al., 2008).

A total of 1219 German school-children (644 boys and 575 girls), ages 10–14 years participated in the study. The APQ was subjected to exploratory and confirmatory factor analysis. Exploratory factor analysis produced five factors that were largely cons...
