It is widely believed that greater initial population diversity leads to improved performance in genetic algorithms. However, this assumption has not been rigorously tested previously. We put this assumption to the test on two benchmark problems and found that greater diversity did not lead to improved performance. This result will require a serious rethinking on the part of the evolutionary co...

This article presents an exemplary case study of an Independent Business Owner (IBO) from multiple case studies on narratives of differently abled persons. The aim of this article is to illustrate mainstreaming disability through an exemplary case of the IBO. The article is informed by the imperatives of critical theory to understand mainstreaming disability. I examine mainstreaming disability ...

Polyamine (PA) titers and biosynthesis follow a basipetal decrease along the tobacco (Nicotiana tabacum) plant axis, and they also correlate negatively with cell size. On the contrary, the titers of arginine (Arg), ornithine (Orn), and arginase activity increase with age. The free (soluble)/total-PA ratios gradually increase basipetally, but the soluble conjugated decrease, with spermidine (Spd...

The tri-space is a concept that has been periodically put forth within geographic information science over the last few decades, under various guises and names (Openshaw 1994; Peuquet 1994; Turton et al. 2000; Yuan 1994). It refers to the conjunction of three spaces: geographic space, time space, and attribute space. These three elements are easily identified in typical spatio-temporal data set...

Many neurological disorders affect men and women differently regarding prevalence, progression, and severity. It is clear that many of these disorders may originate from defective signaling during fetal or perinatal brain development, which may affect males and females differently. Such sex-specific differences may originate from chromosomal or sex-hormone specific effects. This short review wi...
