Farm Deaths And Injuries: Changing Farmer Attitudes And Behaviour On Farm Safety, Kieran O'Connell

Theses

While the Irish agricultural sector accounts for just 6% of the working population of Ireland, it consistently has the highest proportion of fatal incidents of any sector - generally ranging from between 35% and 45% of all workplace fatalities in any given year (Health and Safety Authority, 2015). This was again evident in 2014 where 55% (30 of the 56) of the fatal workplace incidents were in the agricultural sector (Health and Safety Authority, 2015). Agriculture has an ageing workforce with the average age of an Irish farmer now standing at fifty-seven and farmers are eight times more likely to …

Ethnographic Insights Into Safety Communication For Frontline Workers, Kelly Jaunzems, Lelia Green, David Leith, Christine Teague

Research outputs 2014 to 2021

Recent calls for organisation studies to embrace ‘the practice turn’ (Whittington, 2011) have expanded into an understanding of the potential for ethnographic research in occupational health and safety (OHS) research (Pink et al., 2016). The ethnographic project described here, with fieldwork conducted between 2008 and 2010, is one element of this growing appreciation of the potential for qualitative research in industrial settings. Ethnographies have not often been used in OHS settings, and ‘much practicebased knowledge remains undocumented, informal, unspoken and thus unaccounted for’ (Pink et al., 2016, p. 27). This study was motivated by an aim to make explicit the …

Leadership Practices That Improve The Workplace Safety Environment, Nathan Nomore Chikono

Walden Dissertations and Doctoral Studies

Inadequate leadership is the reason workplace accidents in the mining industry remain high, making the industry one of the most hazardous operational activities in the world. Unsafe leadership practices may result in death or injury to workers. A group of 30 mining company leaders from 3 gold mines in Zimbabwe revealed an exception to these hazardous practices, however, notable through their outstanding safety improvement records. To better understand what these practitioners were doing, this multicase study research design explored their strategies to improve the workplace safety environment in the mines. Data were collected using audio-recorded semistructured interviews and document analyses. …

Sexual Harassment Experience, Psychological Climate, And Sex Effect On Perception Of Safety, Kenneth C. Barker

Walden Dissertations and Doctoral Studies

Sexual harassment has significant adverse psychological and physical effects on employees and can negatively impact the workplace, and overall business operations. A gap in current research was identified concerning whether the employee's sex affects employee's perceived workplace sexual harassment climate, sexual harassment experience, and perceived safety from sexual harassment. This study examined the effects of employee workplace sexual harassment experience and perception of workplace sexual harassment psychological climate on employee's perceived safety from sexual harassment moderated by sex. Results showed that perceived workplace sexual harassment climate and employee workplace sexual harassment experience were both significant predictors of perceived safety from …

Consequences Of Job Stress For The Psychological Well-Being Of Teachers, Irvin Sam Schonfeld, Renzo Bianchi, Peter Luehring-Jones

Publications and Research

This chapter examines research on the relationship between job stressors and mental health (depressive symptoms, burnout, and mental disorders such as depression) in teachers. Teachers are exposed daily to job stressors (e.g., student disruptiveness) that have been linked to adverse mental health effects. Epidemiologic research indicates that when compared to members of other groups, teachers experience higher rates of mental disorder, although some studies question that conclusion. Large-scale studies indicate when compared to members of other occupational groups, teachers are at higher risk for exposure to workplace violence, with its adverse mental health consequences. Longitudinal research has linked teaching-related stressors …

Difference Between Male And Female Workers Lifting The Same Relative Load When Palletizing Boxes, André Plamondon, Christian Larivière, Denys Denis, Hakim Mecheri, Iuliana Nastasia

Études primaires

A few biomechanical studies have contrasted the work techniques of female and male workers during manual material handling (MMH). A recent study showed that female workers differed from males mostly in the strategy they used to lift 15-kg boxes from the ground, especially regarding task duration, knee and back postures and interjoint coordination. However, the lifting technique difference observed in females compared to males was perhaps due to a strength differences. The objective of this study was to test whether female workers would repeat the same lifting technique with a load adjusted to their overall strength (females: 10 kg; males: …

Effect Of Local Magnetic Field Disturbances On Inertial Measurement Units Accuracy, Xavier Robert-Lachaine, Hakim Mecheri, Christian Larue, André Plamondon

Études primaires

Inertial measurement units (IMUs), a practical motion analysis technology for field acquisition, have magnetometers to improve segment orientation estimation. However, sensitivity to magnetic disturbances can affect their accuracy. The objective of this study was to determine the joint angles accuracy of IMUs under different timing of magnetic disturbances of various durations and to evaluate a few correction methods. Kinematics from 12 individuals were obtained simultaneously with an Xsens system where an Optotrak cluster acting as the reference system was affixed to each IMU. A handling task was executed under normal laboratory conditions and imposed magnetic disturbances. Joint angle RMSE was …

The Effect Of An 8-Week Stabilization Exercise Program On The Lumbopelvic Rhythm And Flexion-Relaxation Phenomenon, Ali Shahvarpour, Sharon M. Henry, Richard Preuss, Hakim Mecheri, Christian Larivière

Études primaires

Background

Lumbar stabilization exercise programs should normalize the aberrant movements patterns often observed in patients with low back pain. This study aimed to determine the effect of an 8-week lumbar stabilization program on EMG/kinematics measures of the aberrant movement patterns in such patients. A secondary goal was to assess the 8-week test-retest reliability of these measures.

Methods

The patients followed an 8-week lumbar stabilization program while no intervention was carried out on the controls. Before and after this period, kinematics of the spine along with the EMG of paraspinal muscles were recorded during trunk maximal flexion-extension. ANOVAs tested the effect …

Validation Of Inertial Measurement Units With An Optoelectronic System For Whole-Body Motion Analysis, Xavier Robert-Lachaine, Hakim Mecheri, Christian Larue, André Plamondon

Études primaires

The potential of inertial measurement units (IMUs) for ergonomics applications appears promising. However, previous IMUs validation studies have been incomplete regarding aspects of joints analysed, complexity of movements and duration of trials. The objective was to determine the technological error and biomechanical model differences between IMUs and an optoelectronic system and evaluate the effect of task complexity and duration. Whole-body kinematics from 12 participants was recorded simultaneously with a full-body Xsens system where an Optotrak cluster was fixed on every IMU. Short functional movements and long manual material handling tasks were performed and joint angles were compared between the two …

Wellness Education And Job-Related Injuries And Illnesses For Federal Employees, Eunice Scott

Walden Dissertations and Doctoral Studies

Work-related injuries and illnesses may lead to absenteeism, which affects the level of productivity. The purpose of this study was to determine the success of an employee workplace training program on work-related injury and illness rates at selected federal districts within a federal organization. Newman's model, which describes internal and external factors that may have an effect on an individual's health, was the framework that guided this project. A pre-post design was used to compare data from 2 publically available data sets, the Occupational Safety and Health Administration Illness and Injury and the Voice of the Employee Survey, for the …

Influence Of Psychological Empowerment, Leadership, And Climate On Safety Outcomes, Christine Healy

Walden Dissertations and Doctoral Studies

Research has demonstrated that safety outcomes are impacted by workplace risk factors, but also supervisory practices and employee actions. An area that has not been explored is the impact of employee cognitions on safety outcomes defined as work-related injuries. Based on the conceptual framework of psychological empowerment (PE), the purpose of this study was to examine the relationship of employee cognitions as measured by PE as related to leadership and safety climate and the occurrence of work-related injury. The research examined the mediating effect of (PE) on the factors of leadership and safety climate and their relationship to work-related injury. …

Obesity And Obesity Shape Markedly Influence Spine Biomechanics: A Subject-Specific Risk Assessment Model, Farshid Ghezelbash, Aboulfazl Shirazi-Adl, André Plamondon, Navid Arjmand, Mohammad Parnianpour

Études primaires

Underlying mechanisms of obesity-related back pain remain unexplored. Thus, we aim to determine the effect of obesity and its shapes on the spinal loads and the associated risks of injury. Obesity shapes were initially constructed by principal component analysis based on datasets on 5852 obese individuals. Spinal loads, cycles to vertebral failure and trunk stability margin were estimated in a subject-specific trunk model taking account of personalized musculature, passive ligamentous spine, obesity shapes, segmental weights, spine kinematics and bone mineral density. Three obesity shapes (mean and extreme abdominal circumferences) at three body weights (BWs) of 86, 98 and 109 kg …

Études primaires

DAN is a novel derivatizing agent for isocyanate sampling which targets total reactive isocyanate group (TRIG). Field evaluations have been conducted for 4,4’-Methylene diphenyl diisocyanate (MDI) sampling using DAN as the derivatizing agent in a CIP10. The perimidone formed, selective of TRIG, was analyzed in laboratory by liquid chromatography coupled to tandem mass spectrometry. Workplaces using MDI-based polyurethane spray foam and MDI wood product binder were studied. Each study compared the data obtained between the CIP10/DAN, the CIP10/MP, and a reference method. As a first evaluation, the CIP10/DAN sampled simulated MDI spray foam atmosphere in parallel with impingers (reference method) …

Indoor Air Quality, Clint Pinion Jr.

EKU Faculty and Staff Scholarship

An indoor air quality study was conducted on a ‘net-zero energy’ school using a TSI Velocicalc Model 9555-p with probe model 982, passive radon monitors, visual inspection protocol, and an indoor environmental quality survey of school faculty and staff. Average indoor temperature, relative humidity, and carbon dioxide levels in several areas within the school were not within IAQ guidelines. Three rooms on the school’s grounds had radon levels exceeding the action level. Recommended solutions included installing return and supply air ducts in hallways and relative humidity and temperature monitors in classrooms with high-pitched ceilings.
