Development and testing of the aerial porter exoskeleton

Back pain is one of the largest drivers of workplace injury and lost productivity in industries around the world. Back injuries were one of the leading reasons in resulting in days away from work at 38.5% across all occupations, increasing for manual laborers to 43%. While the cause of the back pain can vary across occupations, for materiel movers it is often caused from repetitive poor lifting. To reduce the issues, the Aerial Porter Exoskeleton (APEx) was created. The APEx uses a hip-mounted, powered exoskeleton attached to an adjustable vest. An onboard computer calculates the configuration of the user to determine when to activate. Lift form is assisted by using a novel lumbar brace mounted on the sides of the hips. Properly worn, the APEx holds the user upright while providing additional hip torque through a lift. This was tested by having participants complete a lifting test with the exoskeleton worn in the “on” configuration compared with the exoskeleton not worn. The APEx has been shown to deliver 30 Nm of torque in lab testing. The activity recognition algorithm has also been shown to be accurate in 95% of tested conditions. When worn by subjects, testing has shown average peak reductions of 14.9% BPM, 8% in VO2 consumption, and an 8% change in perceived effort favoring the APEx.

Institutional Investor Activism and Employee Safety: The Role of Activist and Board Political Ideology

Although prior research on shareholder activism has highlighted how such activism can economically benefit the shareholders of targeted firms, recent studies also suggest that shareholder activism can economically disadvantage nonshareholder stakeholders, notably employees. Our study extends this research by exploring whether shareholder activism by institutional investors (i.e., institutional investor activism) can adversely affect employee health and safety through increased workplace injury and illness. Furthermore, deviating from the assumption that financially motivated institutional investor activists are homogeneous in their goals and preferences, we investigate whether the influence of institutional investor activism on employee health and safety hinges on the political ideology of the shareholder activist and of the board of the targeted firm. Using establishment-level data, we find that institutional investor activism adversely influences workplace injury and illness at targeted firms and that this influence is stronger for nonliberal shareholder activists and for firms with a nonliberal board. Our study contributes to shareholder activism research by highlighting how the political ideology of shareholder activists and boards affects the impact of shareholder activism on stakeholders and how shareholder activism can adversely affect the health and safety of employees. Furthermore, our paper also contributes to research on workplace safety and the management of employee relations and human capital resources by highlighting the detrimental effect of a firm’s ownership by investor activists on its employees and how the board’s political ideology may enable a firm to reduce this risk.

Pre-Employment physical capacity testing as a predictor of musculoskeletal injury in Victorian paramedics

BACKGROUND: Paramedic work has periods of intermittent high physical demand, a risk of workplace injury, may be confounded by inherent fitness of the paramedic. OBJECTIVE: This study aimed to identify the nature of workplace musculoskeletal injury, and determine if there was a relationship between pre-employment physical capacity testing (PEPCT) scores and risk of workplace musculoskeletal injury within the paramedic industry. METHODS: A retrospective case review using PEPCT scores and workplace injury (WI) manual handling data collected from 2008 to 2015 by an Australian pre-hospital emergency care provider (Ambulance Victoria), enabled comparison and analysis of two distinct data sets. RESULTS: A total of 538 paramedics were included for analysis with 34 paramedics reporting a workplace musculoskeletal injury from manual handling. The mean time to injury from commencement of employment was 395.4 days (SD 516.2). Female paramedics represented 53.0%and male paramedics represented 47%of the sample. Mean total PEPCT score for the entire sample was 19.1 (SD 2.9) with a range from 16.2–22, while for those reporting injuries it was 18.3 (SD 2.6) with a range from 15.7–20.9. CONCLUSIONS: Musculoskeletal injury amongst Victorian paramedics is more prevalent where the paramedic is female, and/or within three years of commencement of employment. The PEPCT score did not differentiate those at risk of subsequent injury.

Cohort profile: the Ontario Life After Workplace Injury Study (OLAWIS)

PurposeThe substantial economic burden of work-related injury and illness, borne by workers, employers and social security programmes, is primarily attributed to the durations of work disability among workers whose recovery requires a period of absence from work, with the majority of costs arising from the minority of workers with the longest duration absences. The objective of the Ontario Life After Workplace Injury Study is to describe the long-term health and labour market outcomes of workers disabled by work injury or illness after they are no longer receiving benefits or services from the work disability insurance authority.ParticipantsWorkers disabled by a work-related injury or illness were recruited from a sample frame of disability benefit claimants with oversampling of claimants with longer benefit durations. Characteristics of workers, their employers and claimant benefits were obtained from baseline administrative data. Interviews completed at 18 months post injury (T1) and to be completed at 36 months (T2) measure return-to-work and work status; income; physical and mental health; case manager and healthcare provider interactions and employer accommodations supporting return-to-work and sociodemographic characteristics. Of eligible claimants, 40% (1132) participated in the T1 interview, with 96% consenting to participate in the T2 interview.Findings to datePreliminary descriptive analyses of T1 data have been completed. The median age was 50 years and 56% were male. At 18 months following injury, 61% were employed by their at-injury employer, 16% had changed employment and 23% were not working. Past-year prescription opioid use was prevalent (34%), as was past-year cannabis use (31%). Longer duration claimants had poorer function, recovery and health and more adverse labour market outcomes.Future plansMultivariate analyses to identify modifiable predictors of adverse health and labour market outcomes and a follow-up survey of 96% of participants consenting to follow-up at 36 months are planned.

Union, Employer, and compensation system gaps and failures: Workers with injuries perceptions

BACKGROUND: Workers who suffered a workplace injury and submitted a claim with the compensation board in Ontario often faced economic and non-economic costs that provoked depressive feelings, family strain, financial strain, and feelings of diminished self-worth. OBJECTIVE: This qualitative descriptive study aimed to understand the perceived gaps and failures associated with the support systems (e.g., union, compensation and employer) that were in place to assist some male underground workers in Sudbury, Ontario, Canada who had suffered a workplace injury and had a compensation claim. METHODS: Twelve in-depth, in-person, individual, semi-structured interviews were conducted and data were transcribed verbatim and anonymized at the time of transcription. Data analysis followed Braun and Clarke’s guidelines for thematic analysis. RESULTS: Themes that emerged include: unfair and inadequate recognition of an injury; limited communication with stakeholders involved with their claim, including claim adjudicators, challenges when returning to work, and compensation claim system barriers. CONCLUSIONS: Cooperation, collaboration, knowledge transfer, and decreased power imbalances could help to reduce the economic and non-economic strain felt by a worker with an injury. Additionally, a government-funded third-party advocate who knows the medical system, union contracts, the workers’ compensation system, and employer policies and practices could act on behalf of an injured worker.

Structural Vulnerability and Occupational Injury Among Latinx Child Farmworkers in North Carolina

Children as young as ten-years-old can legally work as hired farm labor in the United States. In North Carolina, many hired children are part of the Latinx farmworker community. Agriculture is a hazardous industry, and child workers experience high rates of injury, illness, and mortality. As part of a community-based participatory research study, we draw from thirty in-depth interviews with Latinx child farmworkers aged ten to seventeen to describe their experiences of personal and observed workplace injury and close calls. Nearly all child workers had experienced or observed some form of injury, with several reporting close calls that could have resulted in severe injury or fatality. Overall, children reported a reactive approach to injury prevention and normalized pain as part of the job. Highlighting Latinx child farmworkers’ structural “vulnerability, this analysis contextualizes understanding of workplace injury among this largely hidden population. We offer policy recommendations to protect and support these vulnerable workers.
