Psychological trauma heightens and rigidifies the penchant of humans for dichotomizing others into allies and enemies. With today's "adult delayed recall" controversy a case in point, traumatized individuals tend to unite into tightly knit in-groups that resemble cults and to denigrate others as enemies. This process creates new enmities where objective interests otherwise clash only minimally....

A linear regression of y on x can be approximated by a simple difference: the average values of y corresponding to the highest quarter or third of x, minus the average values of y corresponding to the lowest quarter or third of x. A simple theoretical analysis shows this comparison performs reasonably well, with 80%–90% efficiency compared to the linear regression if the predictor is uniformly ...

E-mail: [email protected] In statistical analyses the researcher should normally use all the relevant information in the data. This argument has been used to advise against the habit of dichotomizing (approximately) continuous variables. However, if, for instance, a continuous variable is not normally distributed, it is possible that an optimal dichotomization can reveal relationships betwee...

BACKGROUND: There is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. In order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. OBJECTIVES: This study aims at describing the origins, arrangements, and branches o...

Postsystolic myocardial segment shortening (PSS) has been observed in dogs and humans by means of ultrasonic crystals but has never been studied specifically. In this study, both subendocardial and subepicardial regional function in the basal circumflex and midventricular anterior myocardium (LAD) was studied during late systole and early diastole with ultrasonic crystals. Fifteen open-chest do...
