Assessing whole body vibration exposure for use in epidemiological studies of back injuries: measurements, observations and self-reports.

Unlabelled: Improved assessment of whole body vibration exposure is needed for epidemiological studies investigating the causes of low back disorders. Vibration was measured on 54 worker-days in five heavy industries, with data collected on observed and self-reported driving conditions, demographics, and vehicle characteristics. Variables significant at p < 0.

Development and evaluation of an observational Back-Exposure Sampling Tool (Back-EST) for work-related back injury risk factors.

We developed and evaluated an observational Back-Exposure Sampling Tool. A literature review suggested 53 exposure variables; these were reduced to 20 following field trials. Kappas for agreement beyond chance between six observers assessing exposures in 72 photos ranged from 0.

Comparing environmental issues in Cuba before and after the Special Period: balancing sustainable development and survival.

Following the Earth Summit in 1992, Cuba designed and implemented a variety of programs, administrative structures, and public awareness activities to promote sound environmental management and sustainable development. This came shortly after the fall of the Soviet Union and the strengthening of the US blockade in 1990, which resulted in a 35% drop in Cuban GDP. This period, referred to as the Special Period, witnessed a decrease in many environmentally damaging activities both by choice and by necessity, but also resulted in many decisions to resuscitate the Cuban economy.

Homelessness and health in Canada: research lessons and priorities.
