From randomness to stability.

The present study describes how the association between randomly chosen variables changes at the successive steps of temporal processes to converge into stable values as suggested by I. Prigogine. To generalize the results to any specific area so results may be applied to concrete problems in different sciences, randomly chosen matrices of random numbers were successively multiplied to generate temporal sequences that before reaching stability had different number of steps. Our results indicate that the obtained poliphasic stability is irreversible.

Intra- and intercultural comparisons of the personality profiles of medical students in Argentina and the United States.

This study was designed to compare the personality profiles of medical students in Argentina and the United States. The ultimate purpose of the research was to study the value of personality measures in predicting academic and professional performances. Participants were 421 medical students in Argentina (254 women, 167 men) and 623 medical students in the United States (207 women, 416 men). Eight personality measures were administered: Perception of Stressful Life Events, Test Anxiety, General Anxiety, Loneliness, Self-Esteem, Locus of Control, Extraversion, and Neuroticism. Intracultural comparisons showed some minor gender differences in personality profiles within each culture (e.g., in the United States, women scored higher than men on the Perception of Stressful Life Events and General Anxiety scales, and in Argentina, women scored higher on the Test Anxiety scale). Intercultural comparisons of personality profiles showed that Argentine medical students obtained higher average scores than did their American counterparts on the Perception of Stressful Life Events, Test Anxiety, General Anxiety, External Locus of Control, Extraversion, and Neuroticism scales. Argentine students scored lower on the Loneliness scale than did their American counterparts. Psychometric findings supported the measurement properties of the personality measures in the two cultures (e.g., construct validity, and internal consistency aspect of reliability). Further study of the implications of the findings in predicting academic attainment in medical school and to physician performance is recommended.
