BACKGROUND The reach and representativeness are seldom examined in worksite weight loss studies. This paper describes and illustrates a method for directly assessing the reach and representativeness of a internet-based worksite weight loss program. METHODS A brief health survey (BHS) was administered, between January 2008 and November 2009, to employees at 19 worksites in Southwest Virginia. ...

It was hypothesized that occupational health and safety (OHS) inspectors who prefer to use autonomy supportive tactics to resolve workplace conflicts (e.g. providing rationale, choices) would be more effective in resolving industry non-compliance with OHS regulations, compared to inspectors who prefer to use coercive tactics (e.g. deadlines, pressure). Preferences for resolving work conflicts w...

BACKGROUND During the 2009 influenza A (H1N1) virus pandemic, the Centers for Disease Control and Prevention did a pilot study to test the feasibility of using national surveillance of workplace absenteeism to assess the pandemic's impact on the workplace to plan for preparedness and continuity of operations and to contribute to health awareness during the emergency response. METHODS Populati...

Reducing the availability of alcohol through alcohol control policies such as excise taxes and the minimum legal drinking age has been effective in reducing a wide range of alcohol-related problems, including traffic crashes, liver cirrhosis, and violence. Alcohol control policies may be classified into two overlapping categories--public and institutional policies. Some policies such as alcohol...

Objective: To investigate the effectiveness of a prevention programme at construction worksites on work ability, health and sick leave. Methods: A total of 15 departments (n=297 workers) from six construction companies participated in this cluster randomized controlled trial, and were randomly allocated to the intervention group (eight departments; n=171 workers) or control group (seven departm...

Cluster randomized controlled trials (cRCTs; also known as group randomized trials and community-randomized trials) are multilevel experiments in which units that are randomly assigned to experimental conditions are sets of grouped individuals, whereas outcomes are recorded at the individual level. In human cRCTs, clusters that are randomly assigned are typically families, classrooms, schools, ...

Edge-sealing, which involves treating the edges of wood products, improves water resistance. This study investigated feasibility edge-sealed cross-laminated timber (CLT) panels to reduce capillary uptake, thereby resisting mould formation. The and vapour permeabilities ten characteristically different single-layer sealant coating systems were systematically determined. Multi-modal assessment le...

The construction industry is a main contributor to Malaysia's economy and yet some projects are considered being extremely unsafe, unhealthy, exposing lot of hazards risks worksites. Hazard Identification, Risk Assessment Control (HIRARC) process commonly used determine evaluate both existing potential on worksite an effective control action plan reduce the identified hazards. HIRARC risk manag...
