Occupational Stress And Coping During A Public Health Emergency: A Mixed-Methods Approach To Understand The Experiences Of Lactation Professionals In Clinical Settings, Mya Michele Carter

Health Services Research Dissertations

Introduction: During public health emergencies, such as the coronavirus 2019 pandemic, breastfeeding is still the recommended feeding option, and mothers and babies may need additional support to reach breastfeeding goals. Pandemic-related, clinic-level restrictions posed new challenges for postpartum mothers and their healthcare teams, including lactation professionals (LPs). The pandemic and subsequent restrictions may have impacted lactation professionals’ work-related stress and limited their ability to provide lactation support. Coping strategies to mitigate occupational stress can be useful in preventing adverse outcomes for both the provider and the patient. The need for continuous support for this profession of healthcare workers is paramount. …

Slip Resistance Evaluation Of 10 Indoor Floor Surfaces, David P. Gilkey, Daniel Autenrieth, Cal Snow, Cody Hays, Sarah Girard, Lorri Birkenbuel

Safety Health & Industrial Hygiene

Slip and fall injuries and fatalities continue to be a signiϐicant problem at work and in the community. Water is the most common contaminant that reduces traction on ϐloors and other walkway surfaces resulting in a slip and fall event. This project investigated 10 common ϐlooring surfaces to assess their slip resistance when dry vs wet and coated vs uncoated. Investigators used the English XL Variable Incidence Tribometer to measure slip resistance under all conditions. Results revealed a signiϐicant (p - value < 0.05) loss of slip resistance when wet vs dry. Investigators also found signiϐicant (p - value < 0.05) increases in traction when using a coating under wet conditions. Researchers support the use of coatings for ϐloors and walkway surfaces that increase traction and reduce the chances of slip and fall events under all conditions.


Seven Attributes Of Risk Assessment, Roger C. Jensen Jun 2024

Seven Attributes Of Risk Assessment, Roger C. Jensen

Safety Health & Industrial Hygiene

Key Takeaways:

- Risk assessment matrixes provide a measurement-like tool for characterizing hazard risk by accounting for severity and likelihood. The best matrix format depends on the needs of the organization.

- The many differences between risk matrixes are due to seven attributes: fundamental elements, orientation, size, axes scales, row and column header terms, risk indicators, and cell colors.

- This article focuses on the two-factor model of risk as a function of severity and likelihood. It was developed with the aim of sharing with the occupational safety community an appreciation for risk assessment matrixes beyond what is typically found …

Occupational Fatality Surveillance Data: Communication Issues, Misunderstandings, And Misuses, Roger C. Jensen May 2024

Occupational Fatality Surveillance Data: Communication Issues, Misunderstandings, And Misuses, Roger C. Jensen

Safety Health & Industrial Hygiene

Every occupational fatality is a tragedy for the person, family, fellow employees, and the employer. Efforts for preventing these deaths involve a multi-faceted approach, one of which is tracking the cases in order to increase understanding of the circumstances involved in the fatal incident. In the United States, the Bureau of Labor Statistics maintains an extensive collection of data on occupational fatalities and publishes the information in multi-page spreadsheets. When properly used, fatality data can be useful for setting research priorities and documenting the importance of particular fatality-related subject matter. For justifying research on prevention, the most useful data involves …

Improving Healthcare Workers’ Biohazardous Spill Safe Handling Skills, Zeina Mhanna, Ahmad Tassi

BAU Journal - Health and Wellbeing

All healthcare workers (HCWs) are exposed to biohazardous material. Biohazardous material may come in the form of spills, posing a risk of infection to (HCWs) who are not trained on how to safely handle them. While international guidelines recommend training HCWs on how to safely handle biohazardous spills in order to improve their skills, there are no studies that tackled this recommendation. The aim of this study is to improve HCWs’ biohazardous spill safe handling skills through training, and to evaluate the association between the HCWs’ improvement level and demographical characteristics.

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer May 2024

Spatial Hearing In Simulated Reverberant Classroom Environments, Gabriel Seth Evan Weeldreyer

Durham School of Architectural Engineering and Construction: Dissertations, Theses, and Student Research

Spatial hearing provides access to auditory spatial cues that promote speech perception in noisy listening situations. However, reverberation degrades auditory spatial cues and limits listeners’ ability to utilize these cues for segregating target speech from competing babble. Hence, spatial unmasking—an intelligibility benefit from a spatial separation between a target and masker—is reduced in reverberant environments as compared to free field. This work tests the hypothesis that interaural decorrelation, the result of increasing reverberation, will broaden the perceived auditory source width with a cascading effect of reduced auditory spatial acuity and subsequently poorer spatial unmasking. To understand the perceptual consequences of …

Well-Being Behaviors And Outcomes In Arkansas Teachers: A Qualitative Analysis Of Teachers In Arkansas During The Covid-19 Pandemic, Ashton Elizabeth Human

Graduate Theses and Dissertations

Introduction: The COVID-19 pandemic introduced new challenges to teachers and emphasized those already existing in the education system. The increased reliance upon technology and lack of administrative support perceived during distance learning led to lower levels of commitment to teaching and increased levels of teacher burnout. Burnout risk is associated with an increased workload, exhaustion from job demands, cynicism toward the professional community and has been shown to have a negative relationship with well-being. Teachers experiencing burnout are unable to establish positive relationships with students, understand students’ needs, stay in contact with trends in the education field, or provide pedagogically …
