Hans Frank was Adolf Hitler’s personal attorney. In Frank’s memoir, published seven years after his execution in 1946 at the International Military Tribunal at Nuremberg, Frank claimed to have uncovered evidence in 1930 that Hitler’s paternal grandfather was a Jewish man living in Graz, Austria, in the household where Hitler’s grandmother was employed. Contemporary historians […]
Abstract: Background: Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. Objective: I begin by considering […]
Implications for best practice in the classroom Abstract: “Hearing” is not a unitary phenomenon, but a complex sensory experience. Many sex differences have been identified in the parameters underlying the experience of hearing, perhaps most importantly in the relationship between the objective amplitude of auditory stimuli and the subjective experience of loudness. These sex […]
ABSTRACT PURPOSE We wanted to survey physicians in the Washington, DC, metropolitan area regarding the frequency with which physicians, teachers, parents, and others first suggest the diagnosis of attention-deficit/hyperactivity disorder (ADHD). METHODS A questionnaire was mailed to all family physicians, primary care pediatricians, and child psychiatrists in greater Washington, DC. In answer to the […]
Summary: Many scholars have argued that Nietzsche’s dementia was caused by syphilis. A careful review of the evidence suggests that this consensus is probably incorrect. The syphilis hypothesis is not compatible with most of the evidence available. Other hypotheses – such as slowly growing right-sided retro-orbital meningioma – provide a more plausible fit to the evidence. View PDF »
A response to Anne Fausto-Sterling Sometimes a child is born with genitalia which cannot be classified as female or male. A genetically female child (i.e., with XX chromosomes) may be born with external genitalia which appear to be those of a normal male. Or, a genetically male child (XY chromosomes) may be born with female-appearing […]
Only the function relating the required pulse frequency to the interburst interval discriminates between the priming effect and the rewarding effect: Separating 2 short bursts of pulses has no effect on their combined rewarding effect, but it enhances their priming effect. There are significant nonscalar differences between animals in the number–current and charge–duration functions for […]
We investigated temporal summation of the rewarding effects of medial forebrain stimulation in 4 male Sprague-Dawley rats by varying the interval separating the 2 short bursts of stimulation given as a reward in a runway. One finding of Exp I—that the reinforcing effect of the 2 bursts was independent of interburst interval—supports a model in […]
