First László Székely and more recently Saharon Shelah and Alexander Soifer have presented examples of infinite graphs whose chromatic numbers depend on the axioms chosen for set theory. The existence of such graphs may be relevant to the Chromatic Number of the Plane problem. In this paper we construct a new class of graphs with ambiguous chromatic number. They are unit distance graphs with ver...

Abstract The present study attempted to investigate the impact of cooperation versus collaboration on college students` reading ability. To fulfill the purpose of the study, 90 participants were chosen from among 140 by means of administering the Nelson Proficiency Test. They were divided into three groups: cooperative group, collaborative group, and control group. A fifty-item multiple-choice ...

N male mealy bugs with the lecanoid chromosome system, one haploid set of I chromosomes becomes heterochromatic early in embryogeny, whereas both haploid sets of female nuclei remain euchromatic. The heterochromatic set was first described by SCHRADER (1921 ) . Later, HUGHES-SCHRADER (1935) showed that this set was not transmitted by the male to its offspring. SCHRADER and HUGHES-SCHRADER (1 93...

A cohort of 19 international polygraph examiner trainees at the Texas Department of Public Safety Polygraph School used the Empirical Scoring System (Blalock, Cushman & Nelson, 2009; Krapohl, 2010; Nelson, Krapohl & Handler, 2008) to evaluate 100 confirmed event-specific criminal investigation polygraph examinations. Bootstrap analytic procedures were used to calculate accuracy profiles and sta...
