Psychopathy is a personality disorder that is strongly linked to criminal behavior. Using [(18)F]fallypride positron emission tomography and blood oxygen level-dependent functional magnetic resonance imaging, we found that impulsive-antisocial psycho

Individual differences in dopamine D2-like receptor availability arise across all brain regions expressing D2-like receptors. However, the interrelationships in receptor availability across brain regions are poorly understood. To address this issue,

Novelty-seeking personality traits are a major risk factor for the development of drug abuse and other unsafe behaviors. Rodent models of temperament indicate that high novelty responding is associated with decreased inhibitory autoreceptor control o

Dopamine (DA) has long been implicated in impulsivity, but the precise mechanisms linking human variability in DA signaling to differences in impulsive traits remain largely unknown. By using a dual-scan positron emission tomography approach in healt

Initial Attitude Differences among Successful, Procrastinating, and 'Withdrawn-from-Course' Students in a Personalized System of Statistics Instruction

Autor: Clarence C. Smith, Ronald B. Purtle, Frederick L. Newman, Dennis L. Young, Stanley E. Ball

Publikováno v: Journal for Research in Mathematics Education. 5:105-113

Techniques of individualized instruction (White, Indelicato, Jerman, & MacPhersen, 1972) and mastery learning (Block, 1971) have apparent promise for mathematics instruction. These techniques offer particular appeal to those instructors responsible f

Publikováno v: The American Journal of Medicine. 11:398-402

1.1. Two cases of acquired diverticula of the jejunum associated with hemorrhage are reported. The diagnosis was made by x-ray preoperatively in both cases. Cure was effected by surgical removal of the involved segment. To date these two patients hav
