approach that simply requires unique numbers, whether generated by the user or the system (or both, in cooperation).

Well-ordering of the Reals presents a major challenge in Set theory. Under the standard Zermelo Fraenkel Set theory (ZF) with the Axiom of Choice (ZFC), a well-ordering of the Reals is indeed possible. However the Axiom of Choice (AC) had to be introduced to the original ZF theory which is then shown equivalent to the well-ordering theorem. Despite the result however, no way has still been foun...

Directed Acyclic Graphs (DAGs) are directed graphs in which there is no path from a vertex to itself. DAGs an omnipresent data structure computer science and the problem of counting given number vertices has been solved 70’s by Robinson. In many applications one needs construct connected control their edges, but adaptation Robinson’s enumeration take this into account led formulas based on incl...

OBJECTIVES To determine how three dimensions of genetic literacy (familiarity, skills, and factual knowledge) fit the hierarchy of knowledge outlined in E.M. Rogers' Diffusion of Innovations to better conceptualize lay understandings of genomics. METHODS A consumer panel representing the US adult population (N = 1016) completed an electronic survey in November 2013. Adjusting for education, w...

In three experiments, using a two-alternative forced-choice task, we obtained depth judgments of displays containing transparent regions. The regions varied in lightness, size, and animation. Observers nearly always strongly preferred one certain depth ordering among the regions, even though their lightness conditions were expected to give rise to ambiguity among possible orderings. This expect...

Within recent years there has been considerable interest in multiple affixation, particularly in explaining why strings of prefixes and suffixes occur in the orders in which they do. The explanations given have been of either a semantic or syntactic nature, as seen in two influential publications that appeared in the same year. Noting cross-linguistic tendencies to fix certain affix orders, Byb...

ion Abstraction is a key principle in every area of computer science – shielding people or programs that make use of a particular software artifact from knowing details that are “internal”. In the database context, this means that users of database systems should be shielded from the internals of database management – what data structures or algorithms are utilized to make access more efficient...

A fundamental principle within human memory research is the idea that repetition (i.e. multiple presentations of a stimulus) and testing (i.e. preliminary recall tasks) both improve recall performance. However, recent evidence suggests that in certain conditions repetition and testing can actually decrease item recall (Peterson, 2011). This study sought to determine whether these negative effec...
