Physicians report a number of barriers to obesity counseling, among them low perceived competence in the ability to counsel. While there is increasing recognition of the need for resident training on counseling, implementation requires residency programs to have the necessary curricula and tools to evaluate training effectiveness. This study’s objective was to describe the development and psych...

In this work Peter principle (in the hierarchical structure any competent member tends to rise to his level of incompetence) is consistently interpreted as the discrete form of the well-known logistic (Verhulst or Maltusian) equation of the population dynamics. According to such interpretation anti-Peter principle (in the hierarchical structure any incompetent member tends to rise to his level ...

Using self-determination theory (Deci & Ryan, 1985) as the theoretical framework, we examined potential antecedents of athlete burnout in 201 elite Canadian athletes (121 females, 80 males; mean age 22.9 years). Employing a cross-sectional design, our primary aims were to investigate the relationships between behavioural regulations and athlete burnout and to examine whether self-determined mot...

The parasitic protozoan Trypanosoma cruzi employs multiple molecular strategies to invade a broad range of nonphagocytic cells. Here we demonstrate that the invasion of human primary umbilical vein endothelial cells (HUVECs) or Chinese hamster ovary (CHO) cells overexpressing the B(2) type of bradykinin receptor (CHO-B(2)R) by tissue culture trypomastigotes is subtly modulated by the combined a...

Male secondary school rugby players (N 271) participated in a study examining role ambiguity, role efficacy, and role performance. A multidimensional measure was used to assess 4 manifestations of role ambiguity in offensive and defensive contexts. Multiple role ambiguity dimensions explained variance in efficacy and performance. Consistent with theorizing by A. Bandura (1997) and R. L. Kahn, D...

PURPOSE This study aimed to establish 1) whether a group difference exists in the motor competence of preschool children at risk for developmental delays with intelligence quotient discrepancy (IQD; refers to difference between verbal intelligence quotient [VIQ] and performance intelligence quotient [PIQ]) and 2) whether an association exists between IQD and motor competence. METHODS Children...
