Public Perspectives on Exposure Notification Apps: A Patient and Citizen Co-Designed Study.

Canada deployed a digital exposure notification app (COVID Alert) as a strategy to support manual contact tracing. Our aims are to (1) assess the use, knowledge, and concerns of the COVID Alert app, (2) identify predictors of app downloads, and (3) develop strategies to promote social acceptability. A 36-item questionnaire was co-designed by 12 citizens and patients partnered with 16 academic researchers and was distributed in the province of Québec, Canada, from May 27 to 28 June 2021.

Assessment of physical work demands of long-distance industrial gas delivery truck drivers.

Aim: The aim of this study was to assess the work-related physical demands of long-distance truck drivers employed by a large gas delivery company in Canada.

Methods: A total of 15 truck drivers participated in a data collection that included self-reporting assessments, field observations, and direct measurements to describe daily tasks organization, postural demands, physical workload, and force exertions.

Results: Truck drivers' work was characterized by long working days ranging from 9.

Assessment of physical work demand of short distance industrial gas delivery truck drivers.

Aim: This study assessed the work-related physical demands of short-distance truck drivers employed by a large gas delivery company in Canada.

Methods: A total of 19 truck drivers participated in the data collection, which included a combination of self-reports, field observations and direct measurements to report on the work shift task composition, postures, physical workload, and force exertions.

Results: Driving (mean of 43% of daily work shift) and delivering gas cylinders to customers (28%) were the main tasks of the truck drivers.

Are per capita carbon emissions predictable across countries?

Background: China and other developing countries in Asia follow similar economic growth patterns described by the flying geese (FG) model, which explains the "catching-up" process of industrialization in latecomer economies. Japan, newly industrialized economies, and China have followed this path, with similar economic development trajectories. Based on the FG model, we postulated a "flying S" hypothesis stating that if a country is located within an FG region and its energy matrix is relatively constant, its per capita CO emission curve will mirror that of "leading geese" countries in the same FG group.

Risk factors associated with self-reported musculoskeletal pain among short and long distance industrial gas delivery truck drivers.

Aim: This study investigated and compared the associations between self-reported exposures to individual as well as work-related physical and psychosocial risk factors for musculoskeletal (MS) disorders and the prevalence of MS symptoms in different body areas among short- (P&D) and long-distance (Bulk delivery) truck drivers working for the same large gas delivery company in Canada.

Methods: 123 truck drivers nationwide participated in this questionnaire-based cross-sectional study. Univariate and multivariate logistic regression analyses were performed.

A Global Perspective on Sulfur Oxide Controls in Coal-Fired Power Plants and Cardiovascular Disease.

Sulfur oxides (SO), particularly SO emitted by coal-fired power plants, produce long-term risks for cardiovascular disease (CVD). We estimated the relative risks of CVD and ischemic heart disease (IHD) attributable to SO emission globally. National SO reduction achieved by emissions control systems was defined as the average SO reduction percentage weighted by generating capacities of individual plants in a country.

ÉquiNanos: innovative team for nanoparticle risk management.

Unlabelled: Interactions between nanoparticles (NP), humans and the environment are not fully understood yet. Moreover, frameworks aiming at protecting human health have not been adapted to NP but are nonetheless applied to NP-related activities. Consequently, business organizations currently have to deal with NP-related risks despite the lack of a proven effective method of risk-management.

A process mapping model for calculating indirect costs of workplace accidents.

Unlabelled: This article follows an earlier one in which four criteria and four bases for the development of an indirect-cost calculation model adapted to the accuracy requirements and time constraints of workplace decision-makers were established. A two-level model for calculating indirect costs using process mapping of the organizational response to a workplace accident is presented. The model is based on data collected in interviews with those employees in charge of occupational health and safety in 10 companies of various sizes in different industry sectors.

Development of an indirect-cost calculation model suitable for workplace use.

Introduction: Occupational Health and Safety (OHS) stakeholders rarely factor the cost of workplace accidents into prevention spending decisions. The lack of consideration of this key information is related to the fact that the scientific literature has failed to provide OHS stakeholders with a cost-calculation tool that is both sufficiently accurate and does not require a data-collection stage ill-suited to the time constraints of workplace decision-makers.

Method: This study reviews the recent literature to identify key elements that should foster the use of indirect-cost calculation methods by decision makers.

Cross-analysis of hazmat road accidents using multiple databases.

Road selection for hazardous materials transportation relies heavily on risk analysis. With risk being generally expressed as a product of the probability of occurrence and the expected consequence, one will understand that risk analysis is data intensive. However, various authors have noticed the lack of statistical reliability of hazmat accident databases due to the systematic underreporting of such events.
