N T H E mouse a peculiar relation exists amongst three lethal mutations I which produce similar effects on development. Animals which inherit two doses of the same lethal die as early embryos, while those which inherit one dose each of two different lethals of this group may be viable. This is the result to be expected when the lethals involved occupy different loci, but in the present case the...

Geoffrey Miller has hypothesized that producing artwork functions as a mating display. Here we investigate the relationship between mating success and artistic success in a sample of 236 visual artists. Initially, we derived a measure of artistic success that covered a broad range of artistic behaviors and beliefs. As predicted by Miller's evolutionary theory, more successful male artists had m...

This study analyses the experienced age discrimination of old European citizens and the factors related to this discrimination. Differences in experienced discrimination between old citizens of different European countries are explored. Data from the 2008 ESS survey are used. Old age is defined as being 62 years or older. The survey data come from 28 European countries and 14,364 old-age citize...

During the Geomatics Engineering Course at the Federal Institute of Technology in Zurich, Switzerland, the students undertake a compulsory internship. This practical work takes place outside the Institute. The main locations for practical work are the following: engineering and planning offices, industrial and geodetic companies. This internship typically takes place during the seventh of ten t...

Cathepsin B, H, L and D activities in liver lysosomes were compared between species. Although cathepsin B and D were detected in bovine, pig, chicken and rat liver, striking species differences were evident for cathepsin H and L. Cathepsin L activity was particularly high in chicken lysosomal extracts, but could not be detected in bovine and pig extracts. Whereas there was no significant cathep...

PURPOSE To evaluate the information that university students have on epilepsy and to compare the differences in attitudes and perception among groups with different levels of information. METHODS A questionnaire with 13 questions regarding knowledge, attitudes and perception about epilepsy was completed by first, third and sixth year medical students and to students from Arts and Science cour...

The Centers for Disease Control and Prevention recommend that health care workers receive influenza immunisation annually. There is no available data on factors predicting influenza immunisation or nurses' acceptance of the need for immunisation in Australia. To determine the predictors of influenza immunisation amongst nurses in Australia, a cross sectional survey of nurses in a 200-bed hospit...

Lorisiform primates (Primates: Strepsirrhini: Lorisiformes) represent almost 10% of the living primate species and are widely distributed in sub-Saharan Africa and South/South-East Asia; however, their taxonomy, evolutionary history, and biogeography are still poorly understood. In this study we report the largest molecular phylogeny in terms of the number of represented taxa. We sequenced the ...

GLAUCOMA has been reported to be common in many tropical countries, observations having been based on various criteria. Elliot (1920) noted that in the Madras Eye Hospital the proportion of surgical operations for glaucoma and cataract were in the ratio of one to four. Chang (1951) reported that 1 75 per cent. of 13,807 ophthalmic out-patients in Peking suffered from primary glaucoma. Dodds (19...
