Electronic media has now pervasively invaded our households and one group of individuals that has clearly been a major and early adopter of such disruptive technology is the adolescent age group. The issue of screen and media exposure as a potentially adverse risk factor to health has now been enunciated for quite some time, and yet despite such ominous correlates, there is still ongoing debate...

This study examined the relationships between older women's comparison styles, physical self-perceptions, and functional fitness. Participants were community-dwelling women (N = 102, age 65-99) living in the mid-Atlantic region of the United States. Individuals were categorized as relying primarily on social comparisons, temporal comparisons, or a combination of both styles. Also of interest wa...

The article of Marc Jamoulle shows the importance of the contribution of general practitioners (GPs) in improving the quality and the efficiency of the health systems. Starting from the concept of quaternary prevention for reducing excessive costs in the preventive procedures, he suggests a change of paradigm in every daily activity of the GP in order to have a stronger ethical approach to the ...

MAPGEN (Mixed-initiative Activity Plan GENerator) is a mixed-initiative system that employs automated constraint-based planning, scheduling, and temporal reasoning to assist the Mars Exploration Rover mission operations staff in generating the daily activity plans. This paper describes the mixed-initiative capabilities of MAPGEN, identifies shortcomings with the deployed system, and discusses o...

Functional and physical impairment are factors believed to lead to declined life satisfaction among older adults. This study aimed to examine life satisfaction among older adults and the influence of frailty. Baseline data from two studies addressing frail older adults aged 80+ in Gothenburg, Sweden, (n=577) were used. Frailty was measured through eight indicators. Life satisfaction was measure...

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...
