His data seemed to demonstrate that occupational levels (and hence social class) are determined mainly by innate, hereditary levels of intelligence.
Our investigation and cohort study demonstrate that occupational exposure, especially among veterinary staff, was a critical factor during this outbreak.
This is the first study to demonstrate that occupational exposures are associated with distinct clinical characteristics in smokers and ex-smokers with COPD, i.e. (i) older age and predominantly male gender, (ii) more frequent respiratory-related work disability or handicap and (iii) increased prevalence of hay fever, asthma, current sputum production, lifetime and current wheezing.
PSWs demonstrated an occupational solidarity that privileged knowledge sharing and mentoring.
For certain xenobiotic agents, these tests accurately differentiate exposure levels, as demonstrated in occupational and environmental epidemiologic studies.
The study demonstrated that occupational exposure to OP pesticides was more closely related to alterations in semen quality than a single measurement of urine OP metabolites.
This paper demonstrated that occupational disparities in suicide rates are dynamic over time, and can be exacerbated by economic downturns such as the 2007 2009 GFC.
Epidemiologic studies have demonstrated that occupational noise exposure is associated with hypertension, but the related mechanism in vascular structural changes is unclear.
Furthermore, the high incidence rate among these workers relative to background rates demonstrates that occupational exposure played a predominant role in disease incidence.
We have previously demonstrated that occupational exposure to irritant gases, especially peak exposure, is associated with increased incidence of adult-onset asthma in pulp mill workers [ 4, 5].
