Beta turns are especially common at the loop ends of beta hairpins; they have a different distribution of types from the others; type I' is the most common, followed by types II', I and II. Additional turn types have been defined by clustering turn conformations within very high-resolution protein structures. [11]
He referred to these factors as "alpha" and "beta". Alpha refers to a combination of agreeableness, conscientiousness and emotional stability (the inverse of neuroticism). Beta is a combination of extraversion and intellect/openness. Digman suggests that Alpha may represent a social desirability factor.
The secondary structure is assigned based on hydrogen bonding patterns as those initially proposed by Pauling et al. in 1951 (before any protein structure had ever been experimentally determined). There are eight types of secondary structure that DSSP defines: G = 3-turn helix (3 10 helix). Min length 3 residues. H = 4-turn helix . Minimum ...
A hairpin is a special case of a turn, in which the direction of the protein backbone reverses and the flanking secondary structure elements interact. For example, a beta hairpin connects two hydrogen-bonded, antiparallel β-strands (a rather confusing name, since a β-hairpin may contain many types of turns – α, β, γ, etc.).
Information processing theory is the approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information processing perspective account for mental development in terms of maturational changes in basic components of a child's mind .

In 1938, the American psychologist Henry Murray developed a system of needs as part of his theory of personality, which he named personology.Murray argued that everyone had a set of universal basic needs, with individual differences among these needs leading to the uniqueness of personality through varying dispositional tendencies for each need; in other words, a specific need is more ...
The polytomous Rasch model is generalization of the dichotomous Rasch model.It is a measurement model that has potential application in any context in which the objective is to measure a trait or ability through a process in which responses to items are scored with successive integers.
