This study aimed to develop scenarios of Iranians’ future participation in leisure-time physical activity (LTPA). To this end, 12 experts the field leisure, sociology, and sport management we...

INTRODUCTION Several national and regional central line-associated bloodstream infections (CLABSI) surveillance programs do not require continuous hospital participation. We evaluated the effect of different hospital participation requirements on the validity of annual CLABSI incidence rate benchmarks for intensive care units (ICUs). METHODS We estimated the annual pooled CLABSI incidence rat...

The purpose of this research is to quantify the potential of waste recycling in the form of participatory scenarios for separation from the source and to study the factors of minimization (reduction) of waste production in a district of Tehran. Amount of waste minimization was determined with considering a couple of citizens' participation scenarios. Source separation of valuable wastes includi...

Studies on experts' understanding of the public have mainly focused on the views of scientists. We add to the literature on constructions of the public by analyzing the views of decision-makers, professional science communicators and scientists involved in 'space' communication on the public and public participation in policy. Findings show that contextual situations and roles determine the way...

OBJECTIVES Low response rates in epidemiologic research potentially lead to the recruitment of a non-representative sample of controls in case-control studies. Problems in the unbiased estimation of odds ratios arise when characteristics causing the probability of participation are associated with exposure and outcome. This is a specific setting of selection bias and a realistic hazard in many ...

The future of mandatory retirement is at least partly driven by changing demographics. In Canada, these demographics include slowing population growth, rapid aging, declining rates of labour force participation, and slowing labour force growth. After reviewing the demographic trends and considering alternate scenarios in labour force participation, we consider the determinants of early departur...

Participatory video scenarios can be used to facilitate user participation in the development of collaborative information systems. At the same time these scenarios promote the empathic understanding of the users. When scenario design is based on a contextual study of the users' work, the scenarios can be focused on the issues that are most challenging from the users' point of view. The number ...
