Defining and describing health has traditionally been the role of medical experts. Although a rich literature has recently established the importance of lay accounts of health, one important gap relates to gay men's accounts of health. Data from 11 focus groups involving 45 gay men were thematically analyzed to investigate gay men's views of health. Two contrasting positions on a possible relat...

Induced and spontaneous wheel running can alter the phase and period (tau) of circadian rhythms in rodents. The relationship between spontaneous running and the phase angle (psi) of entrainment to 24-h light-dark (LD) cycles was evaluated in C57BL/6j mice. With a wheel freely available, psi was significantly correlated with the absolute (r = 0.32) and relative (r = 0.44) amount of activity duri...

We studied polymorphism in all species of birds that are presently known to show intraspecific variation in plumage colour. At least three main mechanisms have been put forward to explain the maintenance of polymorphism: apostatic, disruptive and sexual selection. All of them make partly different predictions. Our aims were to investigate evolutionary causes and adaptive functions of colour pol...

BACKGROUND Many approaches are used to evaluate fall risk. While their properties and performance vary, most reflect performance at a specific moment or are based on subjective self-report. OBJECTIVE To quantify fall risk in the home setting using an accelerometer. METHODS Seventy-one community-living older adults were studied. In the laboratory, fall risk was assessed using performance-bas...

The authors describe their experience in the ambulatory treatment of varicocele. Forty-four patients were treated through an infrapubic approach and only one recurrence was observed. The authors conclude that ambulatory treatment of varicoccle is safe, easy to perform and the patient can resume his daily activity within 48.-72 h.

Although many organisms show daily rhythms in their activity patterns, the mechanistic causes of these patterns are poorly understood. Here we show that host plant volatiles affect the nocturnal behavior of the caterpillar Mythimna separata. Irrespective of light status, the caterpillars behaved as if they were in the dark when exposed to volatiles emitted from host plants (either uninfested or...

Necessary and sufficient conditions for a GADL to become an ADL are obtained interms of congruence relations and proved that every associative GADL is an ADL.

Occupational therapists working with Mexican and Mexican American populations may encounter traditional healing practices associated with curanderismo within a variety of practice settings. Curanderismo is a term referring to the practice of traditional healing in Latin American (Hispanic) cultures. This article reviews from the literature the different types of traditional healers (curanderos/...

This document was developed to help occupa· tional therapists apply Uniform TerminologySecond Edition to practice. A grid format (Dunn, 1988) allows a therapist to systematically identify an individual's deficit and strength areas and to select appropriate activities to address these areas in occupational therapy intervention. On the grid (see Appendix A), the horizontal axis is composed of the...
