Green, Fernando M. and Taveira, Alvaro D. (2012): The Prevalence of Sleep Deprivation Symptoms among Night Shift Nurses and Nurses' Aides at the University Hospital of the West Indies. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 797-800.

“Shift work is unavoidable in essential services such as health care. Even though working long hours into and through the night is often necessary, humans as diurnal creatures suffer adversely from it. The purpose of this study is to assess sleep related problems among nurses and nurses' aides on the night shift at the University Hospital of the West Indies, located in Kingston, Jamaica. This information could hopefully assist hospital decision makers in better policy development. A cross-sectional study design was utilized focusing on the nursing staff on the night shift. Of a possible 176 participants 102 responded,”

Cohen, William J., James, Craig A., Taveira, Alvaro D., Karsh, Ben-Tzion, Scholz, Julie and Smith, Michael J. (1995): Analysis and Design Recommendations for Workstations: A Case Study in an Insurance Company. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 412-416.

“A case study approach was used to determine the effects of task demands, customer needs, and organizational environment on the recommendations for ergonomic redesign in a large pension and insurance organization. The organization was planning a major renovation of workstations and requested assistance with design and implementation. Three job positions were studied using semi-structured interviews, job observations, and measurements of workstations and the office environment. It was found that most work surfaces and chairs were inadequate for VDT tasks, reception counters presented problems for both the employees and claimants, and the use of shared VDTs on a swivel base resulted in eyestrain and poor postures. In addition, there was inadequate storage space and poor housekeeping for all three jobs, as well as lighting and noise problems throughout the office environment. Recommendations were made for new workstations, with pilot testing to be conducted before full-scale implementation. Although existing workstations were inadequate, it was found that task demands were of greatest concern to the employees.”

Taveira, Alvaro D., James, Craig A., Kapp, E. Andrew and Zehel, David (1995): Perception of Risk as Communicated by ANSI Standardized Signal Words. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 945.

“The purpose of this study is to assess the perception of severity and likelihood of injury as expressed by the American National Standards Institute (ANSI) signal words Danger, Warning, and Caution. It was hypothesized that respondents would not be able to distinguish the levels of severity and likelihood associated with each signal word, as implied by the ANSI standard. Twenty-five undergraduate students answered a self-administered questionnaire that asked for ratings of severity and likelihood of each signal word, rankings of the three words in terms of overall risk, and matching of real-life scenarios with the appropriate signal word. The data showed that respondents' ratings of severity and likelihood were significantly higher for Danger than for Warning and Caution (p<.001). The ratings for Warning and Caution did not differ significantly from each other. Concerning the rankings of the three signal words, Danger was consistently ranked highest in terms of overall risk. The switching of the words Warning and Caution in the overall rankings was the most common mistake, made by 20% of the respondents. For the real-life scenarios, respondents were most accurate in labeling the situation that was characterized by the signal word Danger, and made the most mistakes in the situations characterized by the signal words Warning and Caution. Based on these findings, there is reason to believe that the level of risk intended by the standardized signal words is not necessarily perceived by the user.”
