The adult and the larva of Dirrhagofarsus ernae n. sp. are described from the Eastern United States. The genus Dirrhagofarsus is diagnosed and a key to all known species of the genus is provided.

Social support types (abstinence, appraisal, belonging, tangible) were analyzed among a sample of women with criminal justice involvement and substance use disorders (n = 200). Hierarchical linear regression was conducted to examine social support types in relation to changes in abstinence self-efficacy while controlling for incarceration histories. Only abstinence social support and tangible s...

Teaching is a core activity for health professionals that pervades our interactions with patients, learners and colleagues and is explicitly outlined as a core competency under the CanMEDS framework. Unfortunately, as Kloek and colleagues point out in this issue of Perspectives on Medical Education [1], teaching is typically assumed to be a skill present in medical graduates and limited educati...

PURPOSE The goal of this study was to determine which approach to assessing understanding of medical information patients most prefer and perceive to be most effective. METHODS Two videos were shown to participants: (1) a physician explaining a medical condition and its treatment and (2) a physician inquiring about patient understanding of the medical information the patient had been given us...

The Lie group Sol(p, q) is the semidirect product induced by the action of R on R which is given by (x, y) 7→ (ex, e−qzy), z ∈ R. Viewing Sol(p, q) as a 3-dimensional manifold, it carries a natural Riemannian metric and Laplace-Beltrami operator. We add a linear drift term in the z-variable to the latter, and study the associated Brownian motion with drift. We derive a central limit theorem and...

The current study aimed to investigate the impact of individualism, collectivism, and hopelessness on substance use. Hopelessness was hypothesized as a mediator between individualism and substance use, and between collectivism and substance use. We tested the hypothesis using a survey of 641 young rural-to-urban migrants in China. Consistent with our hypotheses, individualistic orientation pred...

Bitches changed abruptly their maternal behavior on 15th and 16th day of the maternal cycle, following an exchange - on the beginning of 15th day - of some puppies from their own litter for other 2-3 days old puppies. The total time of tactile contact with puppies on days 15 and 16 greatly increased as compared with the 13th and 14th day, i.e., the days immediately preceding the exchange of pup...
