Accelerated Life Test Modeling Using Median Rank Regression
… prevalent in both literature and practice is the cumulative exposure model which assumes that, at a given time on test, specimen life is solely driven by the integrated stress history and that current lifetime behavior is path independent of the stress trajectory. This dissertation challenges such …

Lifetime Occupational Exposure to Endocrine-disrupting Chemicals and Postmenopausal Breast Cancer Risk: A Montreal-based Case-control Study (2008-2011)
Background: Exposure to endocrine-disrupting chemicals (EDCs) suspected to increase cumulative lifetime estrogen exposure, may elevate postmenopausal breast cancer risk. Despite evidence from environmental studies, few studies on EDCs have analyzed lifetime occupational exposures and most fail to …

Discrimination-Based Attributions for Mistreatment Affect Continuity of Care
… and Anglo (n = 116) American women. As proposed, cumulative exposure to mistreatment indirectly influenced continuity of care through discrimination based attributions for mistreatment and related emotions. Additionally, it was found that attributing mistreatment to discrimination influenced …

Evaluation of Neurotoxic Effect for the Low-Dose Mixed Organic Solvents Exposed Workers by using Posturography
… age 42.9) were examined. The duration of the exposure ranged from 0.2-30 years (mean 4.2 years) and the life-time cumulative exposure level (CE) was estimated on the basis of each participant's occupational history and biological monitoring. The methods used included static posturography and …

Interactive contribution of peer stress and executive function deficits in predicting adolescent depression
Considering that cumulative exposure to stressful peer events may lead to increases in psychopathology, particularly depression, it is important to examine individual-level factors that may increase the likelihood of experiencing future negative outcomes. This research investigated the interactive …

Evaluating the Potential Impacts of Municipal Wastewater Effluent on Benthic Macroinvertebrates in the Upper Bow River
… assemblages on a longitudinal gradient and cumulative exposure to MWWE in the Bow River were statistically significant and were generally associated with nutrient enrichment (particularly phosphorus). Through the use of different sampling methodologies, MWWE exposures in the experimental …

Urinary phthalate exposure and reproductive outcomes in U.S. women: evidence of dose-response associations in NHANES 2003-2014
… experimental studies suggest that phthalate exposure may affect reproductive function, evidence in women at the population level remains limited and not fully consistent. This study examined the relationship between urinary phthalate metabolites and reproductive outcomes among women aged 18 …

Posttraumatic distress as experienced by adolescents: traumatic stress through adolescent eyes
… life. Findings also suggest that previous and/or cumulative exposure to traumatic stressors may be a key factor in the development of adolescent PTSD symptoms, and that endorsing fear of serious injury or death is associated with increased symptoms of PTSD among adolescents. These findings support …

Chronic trauma effects on personality trait trajectory in police officers
The impact of chronic trauma exposure on personality trajectories over time was examined in a sample of urban police officers. Scores from a personality measure taken in pre-hire psychological evaluations were compared with follow up scores administered for this study five to ten years later. An …
