Effects of a behavior-based safety observation program: Promoting safe behaviors and safety climate at work.

BACKGROUND: Behavior-based safety (BBS) programs promote coworkers observing and correcting each other's at-risk behaviors on site; the idea behind BBS programs is to create a cultural shift in a company where it is acceptable for coworkers to stop anyone, at any time, from working in an unsafe manner. OBJECTIVE: The main objective of this study is to examine the impacts of a BBS observation program in the construction industry. METHODS: The subject, an electrical contracting company, implemented the BBS program in January 2019. This study utilized multiple data sources: the company's incident data, BBS program report data, and surveys, including the Safety Climate Assessment Tool for Small Contractors. A total of 3,891 at-risk behaviors from the BBS reports, including 600 comments, and 141 survey responses were analyzed. RESULTS: The most frequently reported at-risk behavior was the line of fire, and the at-risk behaviors were often observed when workers conducted tasks, such as running or pulling wires, installing devices, and installing lights. The overall perception of safety climate was high, and the respondents reported that the safety climate had improved since the adoption of the BBS program. Overall, implementing the BBS program benefited in cultivating the company's collective safety climate. CONCLUSION: As a result of the BBS program, the company implemented better communication strategies for their safety meetings on the most frequently reported at-risk behaviors, replacing safety gears with higher quality ones, and redesigning online safety training to better reflect the identified tasks that were associated with more at-risk behaviors.

Multidimensional Environmental Factors and Sleep Health for Aging Adults: A Focused Narrative Review.

The timing, amount, and quality of sleep are critical for an individual's health and quality of life. This paper provides a focused narrative review of the existing literature around multidimensional environments and sleep health for aging adults. Five electronic databases, Scopus, Web of Science, PubMed/Medline; EBSCOhost, PsycINFO (ProQuest), and Google Scholar yielded 54,502 total records. After removing duplicates, non-peer reviewed academic articles, and nonrelevant articles, 70 were included for review. We were able to categorize environmental factors into housing security, home environment, and neighborhood environment, and, within each environmental category, specific elements/aspects are discussed. This paper provides a comprehensive map connecting identified levels of influence (individual, home/house, and neighborhood-level) in which subfactors are listed under each level of influence/category with the related literature list. Our review highlights that multidimensional environmental factors can affect aging adults' sleep health and eventually their physical, mental, and cognitive health and that sleep disparities exist in racial minorities in socioeconomically disadvantaged communities in which cumulative environmental stressors coexist. Based on this focused narrative review on the multidimensional sleep environments for aging adults, knowledge gaps are identified, and future research directions are suggested.

Academic library spaces and student activities during the COVID-19 pandemic.

A library in higher education plays a primary role in students' learning on campus. In addition to individually-focused studying, students come to a library for various purposes, such as group learning, collaborating, and socializing. To support students' different types of learning, appropriate physical and functional environments of the spaces must be provided. However, the environmental effects of learning spaces have not been explored extensively. Additionally, the COVID-19 pandemic has forced students to remain and study at home for extended periods, and it is expected that the pandemic experience has affected students' space use patterns. This study aims to examine the effect of the pandemic on students' library usage and to investigate the necessary environments to effectively support students' learning activities. Data was collected via interviews with 12 students. One of the main findings is that, even though students used the library less during the pandemic, they expected to use it as much as pre-pandemic or even more after the pandemic. Furthermore, both physical and functional environments were associated with the study performance and wellbeing of the students. Therefore, understanding students' learning activities and preferred environments in a library is critical to providing appropriate spaces supporting students' learning performance and wellbeing.

Building spatial layout that supports healthier behavior of office workers: a new performance mandate for sustainable buildings.

BACKGROUND: The pursuit of efficiency and the permeation of communication technologies in modern workplace have increased prolonged sitting and physical inactivity among the white-collar workforce. Physical inactivity is a major risk factor for developing various chronic diseases and obesity. OBJECTIVE: This study intends to understand the impact of physical environment on both voluntary and imperative physical activity levels in an office building, and to collect evidence for design suggestions to encourage office workers' activity level on a daily basis. This study examined how proximity from individual workstations to various shared service and amenity spaces in the workplace (e.g., meeting spaces, copy areas, kitchens, restrooms, elevators, and stairs) is associated with office workers' physical activity level (e.g., sedentary and non-sedentary behavior) and their environmental and job satisfaction. PARTICIPANTS AND METHODS: To objectively measure physical activity, twenty-six office workers, in a three-story office building, wore accelerometers for three consecutive days at work. Environmental and job satisfaction of office workers was measured by a questionnaire. Proximity variables were measured using the floor plans of the subject building. CONCLUSIONS: Participants on average were sedentary for 80% of the time during the study. Proximity to several service and amenity areas was positively associated with step counts and job satisfaction.
