BACKGROUND Throughout industrialized countries, tobacco consumption is seen as the predominant driver of both the trend and the extent of gender differences in life expectancy. However, several factors raise doubts to this generalization. We hypothesize that the impact of smoking on the gender gap is context-specific and differs between populations. METHODS We decompose the gender differences...

When parents select similar sounding names for their children, do they set themselves up for more speech errors in the future? Questionnaire data from 334 respondents suggest that they do. Respondents whose names shared initial or final sounds with a sibling's reported that their parents accidentally called them by the sibling's name more often than those without such name overlap. Having a sib...

BACKGROUND AND PURPOSE Left-sided strokes are reported to be more common than right-sided strokes, but it is unknown whether they occur more often or are simply recognized more easily by clinicians. In a large unselected community-dwelling population, we examined the frequency of clinical left- and right-sided strokes and transient ischemic attacks (TIAs) and compared it with the frequency of l...

Although the field of natural language processing has made considerable strides in the automated processing of standard language, figurative (i.e., non-literal) language still causes great difficulty. Normally, when we understand human language we combine the meaning of individual words into larger units in a compositional manner. However, understanding figurative language often involves an int...

Recent reports have called into question the widespread belief "that mutations arise continuously and without any consideration for their utility" (in the words of J. Cairns) and have suggested that some mutations (which Cairns called "directed" mutations) may occur as specific responses to environmental challenges, i.e., they may occur more often when advantageous than when neutral. In this pa...

If philosophical moral reflection improves moral behavior, one might expect ethics professors to behave morally better than socially similar non-ethicists. Under the assumption that forms of political engagement such as voting have moral worth, we looked at the rate at which a sample of professional ethicists-and political philosophers as a subgroup of ethicists-voted in eight years' worth of e...
