This paper develops a theoretical explanation for the sexual sadistic serial murderer's heterosexual lifestyle. The theoretical formulation developed draws upon Glasser's (1984) control theory and Marshal's (1989) general theory of sexual offending. It synthesizes Glasser's propositions around idealized life style and mental pictures and Marshal's propositions on intimacy. The theoretical formu...

For high-level functional categories that are represented in almost all prokaryotic genomes, the numbers of genes in these categories scale as power-laws in the total number of genes. We present a comprehensive analysis of the variation in these scaling laws across prokaryotic clades and lifestyles. For the large majority of functional categories, including transcription regulators, the inferre...

Although a link between lifestyles and social class has long been acknowledged, marketers have more closely identified lifestyles with psychographics and therefore with psychological segmentation. We propose that the origins of lifestyle are more correctly reflected in Weber’s approach to status and that it can be viewed more appropriately as the most relevant form of social stratification for ...

All plants in natural ecosystems are thought to be symbiotic with mycorrhizal and/or endophytic fungi. Collectively, these fungi express different symbiotic lifestyles ranging from parasitism to mutualism. Analysis of Colletotrichum species indicates that individual isolates can express either parasitic or mutualistic lifestyles depending on the host genotype colonized. The endophyte colonizati...
