Abstract In October 2018, the Canadian federal government passed the Cannabis Act, making Canada the first G7 nation to legalize the possession and consumption of recreational cannabis nationwide. Given the potential health and safety implications, this makes it a pivotal time for both policy makers and researchers to understand the effects of cannabis use and the implications in the workplace. In response to legalization, the Canadian Armed Forces (CAF) was one of the first major organizations to create a policy specifically targeting cannabis use for its military personnel, with directives outlining expectations for standards of conduct, and general and specific prohibitions relating to the possession and consumption of cannabis products. An important part of understanding the potential impact of cannabis use in the Canadian military and the suitability of the current policy is to first determine the proportion of CAF members that have consumed cannabis since its legalization. The first available data on this comes from the Recruit Health Questionnaire, a health and lifestyle survey completed by military recruits early in their basic training. 1,219 recruits completed the survey between October 2019 (exactly one year post-legalization) and February 2020 (88% response rate). Preliminary results suggest that one-third (34%) of recruits reported having consumed cannabis during the 12 months prior to starting basic training, and since the Cannabis Act came into effect. The vast majority (95%) of this group reported having consumed cannabis on more than one occasion. Given these large proportions, it is imperative that we continue to study the medical, behavioural, and cognitive effects of cannabis to understand if the current guidelines set out in the CAF policy on recreational cannabis use are adequate. Constant monitoring and, as necessary, updates to the policy, are essential to continue ensuring the safety of CAF members and the public, and an operationally ready force. Key messages Preliminary results suggest that one-third of Canadian Armed Forces recruits have consumed cannabis since its legalization, with 95% of this group having consumed it on more than one occasion. Given the potential health and safety implications, the Canadian Armed Forces policy on cannabis consumption must be constantly monitored and updated to ensure a safe and operationally ready force.

In 2011, “What’s Cooking, Uncle Sam? The Government’s Effect on the American Diet” (WCUS) was exhibited at the Lawrence F. O’Brien Gallery of the National Archives Building in Washington, DC. Afterward, it toured the country, visiting the Centers for Disease Control and Prevention’s (CDC) David J. Sencer Museum in Atlanta, the National Constitution Center in Philadelphia, and the Kansas Museum of History in Topeka. The exhibition website states that WCUS was “made possible” by candy corporation Mars, Incorporated. WCUS featured over a 100 artifacts tracing “the Government’s effect on what Americans eat.” Divided into four thematic sections (Farm, Factory, Kitchen, and Table), WCUS moves from agrarianism, through industrial food production and into mess halls, cafeterias, and individual kitchens. Photos, documents, news clippings, and colorful propaganda posters portray the government as a benevolent supporter of agriculture, feeder of soldiers and children, and protector of consumer health and safety. Visitors are positioned as citizens in an ideological mélange of paternalism and patriotism. In this rhetorical walk-through of the exhibition, we consider the display of archival materials for purposes of positioning, in consideration of past and present issues of diet and governance. Making explicit unstated assumptions, we claim that, although propagandistic artifacts take on different meanings to those viewing them decades later as memorabilia, they maintain their ideological flavor.

The success of every construction projects largely depends on the level of commitment of the clients. This study examined the factors influencing the level of clients’ commitment to sustainable construction practices in Nigeria. A questionnaire survey was use to collect data from the public and private construction clients on the level of influence of 16 factors extracted from the literature. A total of 182 valid questionnaires were used for analysis. The result revealed that nine factors with weighted average (W) 0.8≤W≤1 have a high level of influence, whereas seven factors with 0.6≤W≤0.8 have a high-medium level of influence on the clients’ commitment. However, the five most influential factors were: client knowledge and awareness, Cost implication and mechanism of financial involvement, economic value and return on investment, end-user/client perception and preference, and health and safety implications. The result further revealed that there is significant difference on how these factors influence the level of commitment of sustainable construction practices of the public and private clients. The study suggested that the disparity was due to the differences in the level of knowledge, awareness, involvement and commitment of the public and private clients to sustainable construction concept. Hence, it is important to optimize the level of knowledge and awareness of the clients, about the cost, benefits/profits, and health and safety implications of sustainable construction practices so as to promote the level of client’s commitment to sustainable construction practices. It recommended for adequate client involvement throughout the sustainable construction life cycle and a sustained awareness campaign, championed by relevant government agencies and professional organizations through different public programs so as to increase the clients’ commitment and desirability to demand for more sustainable construction projects.

An experimental program of research was carried out to assess the potential health and safety effects of participating in virtual environments (VEs) via head-mounted displays (HMDs). This paper presents the results obtained from nine experiments examining the effects experienced during and after participation in a variety of VR systems, VE designs, and task requirements, for a total participant sample of 148 individuals. A combination of methods including self-report scales, performance measures, physiological indicators, observation, interview, and user attitude/opinion questionnaires were used to measure simulator (VE) sickness, postural instability, psychomotor control, perceptual judgment, concentration, stress, and ergonomics effects. Greatest effects across the different systems, VEs, and exposure times were found for sickness symptoms and physiological measures, with some concern over postural instability and physical ergonomics, also. Although many of the effects were relatively minor and short lived, they were serious for five percent of participants and irritating for a considerable percentage more. The aetiology of the effects is sufficiently different to that for simulators or transport systems to justify us using a new term, virtual reality-induced symptoms and effects (VRISE). Implications are drawn for VR system design, VE specification, and the ways in which industrial use of VR/VE should be planned and supported.

This chapter discusses teleworking/telecommuting from a legal perspective, as applied to the management of teleworkers. The main issues covered are the definition of teleworking, employment relationships and employment contracts for telecommuting, health and safety implications of teleworking, and other legal-related considerations to be taken. Lastly, implications are discussed for both the management of organizations and the legal establishment. This chapter examines teleworking from a legal point of view. Although it was written from a European (in particular, British) perspective, we have tried to use material with relevance extending beyond the boundaries of one specific country, and the arguments are intended and expected to apply to a much wider audience and circumstances.

The decontamination and decommissioning of the Department of Energy Rocky Flats site has resulted in a number of large waste items that need to be shipped to waste collection areas. However, in order to transport these items, they need to be size-reduced and packed into DOT-approved containers such as standard industrial packaging (IP) waste containers. The size reduction process costs time and money while exposing workers to potential health and safety risks. Spray-on polyurea coatings have the potential of allowing large items to be encapsulated by the coating and transported without having to size-reduce the items. The Hemispheric Center for Environmental Technology (HCET) at Florida International University (FIU) recently performed an engineering analysis that includes mechanical testing and small-scale drop tests to determine the feasibility of using a spray-on polyurea coating for shipment of large, low-level waste items instead of using standard IP waste containers.
