This article is a thematic reflection. It aims at presenting volunteer work as an alternative for promoting health for elders in Brazil. Having as a starting point the definition of volunteer work, this study contextualizes this type of activity in Brazilian society, explaining it also as an instrument that makes possible for people to experience an active and healthy aging process. The text pr...

We conducted a field study to test the applicability of the job characteristics model (JCM) in volunteer organizations and examine the impact of job characteristics on volunteer motivation, satisfaction and intent to quit, as well as test a measure of volunteer performance. One hundred and twenty-four volunteers completed measures of job characteristics, motivation, satisfaction, and intent to ...

We analyzed a large patient and volunteer study of external respiratory motion in order to develop a population database of respiratory information. We analyzed 120 lung, liver, and abdominal patients and 25 volunteers without lung disease to determine the extent of motion using the Varian Real-Time Position Management system. The volunteer respiratory motion was measured for both abdominal and...

Volunteer computing uses the free resources in Internet and Intranet environments for large-scale computation and storage. Currently, 70 applications use over 12 PetaFLOPS of computing power from such platforms. However, these platforms are currently limited to embarrassingly parallel applications. In an effort to broaden the set of applications that can leverage volunteer computing, we focus o...

We report results from the first investigation of the human metabolism of arsenic-containing lipids (arsenolipids), significant arsenic constituents of some seafood products. Two male volunteers ingested canned cod liver and the arsenic metabolites in their urine were monitored by high-performance liquid chromatography inductively coupled plasma mass spectrometry over a 66-h period. Volunteer A...

OBJECTIVE The goal of this work was to assess the applicability of socioemotional selectivity theory to the realm of volunteerism by analyzing data drawn from the September 2002 Current Population Survey Volunteer Supplement. METHODS Total number of organizations volunteered for and total number of hours engaged in volunteer activities were utilized to obtain measures of volunteer hours per o...

Following the successful inclusion of virtualisation to volunteer computing for theory simulations back in 2011, the use of volunteer computing with BOINC and CernVM has been extended to cover simulations for the LHC experiments ATLAS, CMS and LHCb. This paper describes the status of the BOINC volunteer computing platform at CERN used for LHC@home and how it has been designed ...

Using two waves of panel data from Americans' Changing Lives (House 1995) (N = 2,681), we examine the relationships between volunteer work in the community and six aspects of personal well-being: happiness, life satisfaction, self-esteem, sense of control over life, physical health, and depression. Prior research has more often examined the effects of voluntary memberships than of volunteer wor...

The number of individuals who share their time and talents as volunteers is on the rise. In 1993 it was reported that formal volunteer work was performed by 89.2 million Americans, worth an estimated $182.3 billion (Grube & Piliavin, 2000). In particular, most hospitals rely on volunteers to complete a multitude of tasks that both the clinical and the administrative stafFcannot fit into their s...
