Religious affiliation and psychopathology in a Mexican-American population.

Studied 54 Protestant and 54 Catholic Mexican-American Ss of similar levels of acculturation, education, and socioeconomic background. Evaluations of psychopathology were derived from the L-R sections of the Cornell Medical Index and behavioral observations. The lower rate of pathological responses by Protestant Ss was attributed to the social support offered by the small, intimate congregations with their strong, paternal leadership and the Protestant doctrines of asceticism and individual responsibility which contribute to impulse control.

Personality profiles of gifted women: Psychologists.

Compared the responses to the 16PF of 124 highly successful women psychologists with women in general, college women, and successful academic men to identify personality factors enabling these women to succeed in spite of powerful sex-role expectations to the contrary. In terms of test scores, women psychologists were significantly more intelligent, socially aloof, dominant, serious, adventuresome, sensitive, flexible, imaginative, insightful, unconventional, secure, self-sufficient, and less anxiety-prone than women in general and college girls. Despite similar test profiles of successful academic men and women, the women scored higher on intelligence, radicalism, and super-ego strength, and lower on self-sentiment. Women who published extensively were more exacting and socially aloof than less productive women psychologists. (28 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relations of heart rate to motor activity and arousal in the rat.

Recorded heart rate in 9 male hooded rats and 1 male albino rat under conditions of satiation or food deprivation. Increased heart rate was associated with phasic movement or an erect posture. These 2 factors appeared to combine during face washing or licking of the back, resulting in heart rates up to 500/bpm. Food deprivation up to 47 hr. had no direct effect on heart rate. It is suggested that many of the results of studies relating heart rate in the rat to learning, motivation, arousal, etc. may be secondary effects of changed behavior patterns such as an increase or decrease in grooming.

Problem solving as a function of children's defensiveness and parental behavior.

The performance of 2 groups of 16 5th-grade boys, one low defensive and low anxious (LD) and the other high defensive and low anxious (HD) on the Defensiveness and Test Anxiety Scales for Children, was compared on the Porteus Maze Test taken with mothers absent and on a different form of the Porteus plus a jigsaw puzzle test with mothers present. Mothers were rated on a set of rating scales as they helped their sons with the puzzle. The results suggest that (a) discrepancies between ability and qualitative performance in defensive boys are a function of defensiveness whereas such discripancies in quantitative performance are a function of certain salient components of the test situation, and (b) communication is less effective in families of HD boys than in families of LD boys.

Correlation of the expansion segments in mammalian rRNA with the fine structure of the 80 S ribosome; a cryoelectron microscopic reconstruction of the rabbit reticulocyte ribosome at 21 A resolution

Samples of 80 S ribosomes from rabbit reticulocytes were subjected to electron cryomicroscopy combined with angular reconstitution. A three-dimensional reconstruction at 21 A resolution was obtained, which was compared with the corresponding (previously published) reconstruction of Escherichia coli 70 S ribosomes carrying tRNAs at the A and P sites. In the region of the intersubunit cavity, the principal features observed in the 70 S ribosome (such as the L1 protuberance, the central protuberance and A site finger in the large subunit) could all be clearly identified in the 80 S particle. On the other hand, significant additional features were observed in the 80 S ribosomes on the solvent sides and lower regions of both subunits. In the case of the small (40 S) subunit, the most prominent additions are two extensions at the base of the particle. By comparing the secondary structure of the rabbit 18 S rRNA with our model for the three-dimensional arrangement of E. coli 16 S rRNA, these two extensions could be correlated with the rabbit expansion segments (each totalling ca 170 bases) in the regions of helix 21, and of helices 8, 9 and 44, respectively. A similar comparison of the secondary structures of mammalian 28 S rRNA and E. coli 23 S rRNA, combined with preliminary modelling studies on the 23 S rRNA within the 50 S subunit, enabled the additional features in the 60 S subunit to be sub-divided into five groups. The first (corresponding to a total of ca 335 extra bases in helices 45, 98 and 101) is located on the solvent side of the 60 S subunit, close to the L7/L12 area. The second (820 bases in helices 25 and 38) is centrally placed on the solvent side of the subunit, whereas the third group (totaling 225 bases in helices 18/19, 27/29, 52 and 54) lies towards the L1 side of the subunit. The fourth feature (80 bases in helices 78 and 79) lies within or close to the L1 protuberance itself, and the fifth (560 bases in helix 63) is located underneath the L1 protuberance on the interface side of the 60 S subunit.
