Two recent studies provide convincing evidence that speciation without geographic isolation--sympatric speciation--has occurred within isolated island habitats, but we remain ignorant of how frequent the process really is.

The Dunning Kruger Effect, which states that individuals with little or no knowledge about a subject have more self-confidence than experts, was first put forward as result of social experiment in 1999. Over time, the concept has become theory been accepted literature and studies some branches science translated into Turkish Cahil Cesareti. In this direction, aim study is to analyze Google sear...

in this paper we find sufficient conditions on primitive inverse topological semigroup s under which: the inversion inv : (h(s)) (h(s)) is continuous; we show that every topologically periodic countable compact primitive inverse topological semigroups with closed h-classes is topologically isomorphic to an orthogonal sum p i2= bi (gi) of topological brandt extensions bi (gi) of countably compac...

the main aim of this article is to study (v,k,λ)-symmetric designs admitting a flag-transitive and point-primitive automorphism group g whose socle is psl(3,q). we indeed show that the only possible design satisfying these conditions is a desarguesian projective plane pg(2,q) and g > psl(3,q).

We offer novel evidence that a Black man appears lighter in the mind’s eye following a counter-stereotypic prime, a phenomenon we refer to as skin tone memory bias. In Experiment 1, participants were primed subliminally with the counterstereotypic word educated or with the stereotypic word ignorant, followed by the target stimulus of a Black man’s face. A recognition memory task for the target’...
