Positive selection on a new mutant allele can increase the frequencies of closely linked alleles (through hitchhiking), as well as create linkage disequilibrium between them. Because this disequilibrium is induced by the selected allele, one may be able to identify loci under selection by measuring the influence of a candidate locus on pairwise disequilibrium values at nearby loci. The constrai...

A statistical departure from Mendel's law of segregation is known as transmission ratio distortion. Although well documented in many other organisms, the extent of transmission ratio distortion and its influence in the human genome remains incomplete. Using Genetic Analysis Workshop 19 whole genome sequence data from 20 large Mexican American pedigrees, our goal was to identify potentially dist...

Backward disequilibrium is observed frequently in daily clinical practice. However, there are no epidemiological data concerning this postural disorder. Defined by a posterior position of the centre of mass with respect to the base of support, backward disequilibrium is abnormal postural behavior, usually characterized by a posterior trunk tilt in standing and sitting positions, which predispos...

There are two opposing views concerning intuitive cases of wage exploitation. The first denies that they exploitation at all. It is based on the nonworseness claim : there nothing wrong with a discretionary mutually beneficial employment relationship. second reasonable view some relationships can be exploitative even if employers have no duty towards their employees. This article argues does no...
