Boykin, Gary L., Rice, Valerie J. and Alfred, Petra E. (2012): Age-Related Balance Among Soldiers. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 149-152.
“Postural degradation can begin as early as age forty men and women, but little information is available regarding postural stability among the 'younger-old' working population. The purpose of this research was to examine younger (≤ 38 yrs, n=14) and older (≥ 39 yrs, n=14) Soldiers' balance using a biomechanical orthogonal balance platform. Twenty-Eight active duty Soldiers between the ages of 28-56 years (mean = 40.62, median = 38.8) participated. Soldiers assumed a tandem stance for 22 seconds, with their dominate foot forward for two trials, first with eyes open, then with eyes closed. T-test results (p < .05) indicate significant Center of Pressure displacement differences in Average Displacement Y axis (ADY- fore and aft) with eyes open (t(26) = -2.46, p=.021) and Average Velocity eyes open (t(26) = -2.30, p=.030), but not for Average Displacement X axis (ADX -- medial-lateral) (t(26) = -1.62, p=.117) eyes open, (t(26) = -.463, p= .647) eyes closed. These findings may provide relevant information to military leaders responsible for physical training and combat initiatives that involve balance efficacy, and to build a case for the need to develop normative balance data based on age.”

Alfred, Petra E. and Rice, Valerie J. (2012): Age Differences in Simple and Procedural Reaction Time Among Healthy Military Personnel. In: Proceedings of the Human Factors and Ergonomics Society 2012 Annual Meeting 2012. pp. 1809-1813.
“Knowledge of cognitive processing changes among adults is important as it can impact their work and home functioning. However, basic cognitive changes due to aging among healthy working adults are either not as well documented or focus on adults over 60 years of age. The purpose of this study was to examine the performance of younger (age 21-38) and older (age 39-58) military personnel on the Automated Neuropsychological Assessment Metric (ANAM) tests of simple and procedural reaction time. Descriptive statistics including correlation analyses were used to examine the data. Independent samples t-tests were used to compare the groups. Linear regression was used to predict age based on the three reaction time tests. Results of the correlation analyses failed to find a significant relationship between age and reaction time (p > .05). Results of the t-tests failed to find significant mean differences between younger and older participants (p > .05). Results of the linear regression analyses failed to find significance for predicting age based on the selected reaction time measures (p > .05). These results appear to support findings that age-related differences in reaction time do not occur during less complex reaction time tasks.”

Alfred, Petra E. and Rice, Valerie J. (2011): The Relationship Between Self-reported Hours of Sleep, Perceptions of Tiredness and Academic Performance in a Military Training Environment. In: Proceedings of the Human Factors and Ergonomics Society 55th Annual Meeting 2011. pp. 630-634.
“Prior research has demonstrated a relationship between a student's amount of nightly sleep and their grades. The purpose of this study was to examine the relationship between self-reported sleep on weekdays and weekends, subjective feelings of tiredness, and academic performance among Health Care Specialist students at Ft. Sam Houston, TX. A survey was administered during the first two weeks of training and final academic performance was recorded (pass/fail status and final course average) for 153 student volunteers. Spearman rho correlations and Chisquare analyses were conducted on the ordinal data. Results indicate a positive correlation between weekday hours-of-sleep and weekend hours-of-sleep (p < .05). However, only self-reported hours of sleep on weekends was significantly correlated with academic performance (p < .05). An interpretation of findings, implications for course design, and ideas for future research are discussed.”

Lueder, Rani and Rice, Valerie J. (2008): Ergonomics for Children: Desiging Products and Places for Toddlers to Teens. United States, Taylor and Francis
“This text, Ergonomics for Children, is designed to be a users' manual for any adult who designs for children, must 'teach&reach' children, who supervises children, or who develops policies and programs for children. It presents up-to-date research findings and then translates that information into practical guidelines for designing products (toys, playgrounds), places (day cares, museums, furniture, homes), and programs (teaching handwriting and wayfinding) so they match children's dimensions and capabilities, while simultaneously challenging them to continue their learning and growth.”

Rice, Valerie J. (ed.) (1998): Ergonomics in Health Care and Rehabilitation. Boston, USA, Butterworth-Heinemann
“This unique book teaches therapists how to use ergonomics to optimize human performance and improve patient health. It explains what recommendations should be made to industry to promote healthy work habits and decrease the incidence of musculoskeletal injuries and discusses proper body mechanics, work simplification techniques, and recommendations for ergonomic equipment.
This clinical reference describes the use of ergonomics in health care and rehabilitation as part of the process to optimize human performance within the context of a person's environment. Rehabilitation professionals provide consultation to industry to promote healthy work habits and decrease the incidence of musculoskeletal injuries. Proper body mechanics, work simplification techniques, and recommendations for ergonomic equipment educate people on how to work more safely and productively within the work environment. The end result is fewer injuries (with less money paid to workers' compensation) and better productivity. Contributing authors represent ergonomists, occupational and physical therapists, engineers, psychologists, physicians, lawyers, and architects, and provide a clinical reference that is applicable to all health care, rehabilitation, and ergonomic professionals.

Sharp, Marilyn A., Rice, Valerie J., Nindl, Bradley C. and Mello, Robert P. (1995): Maximum Acceptable Load for Lifting and Carrying in Two-Person Teams. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 640-644.
“The purpose of this study was to determine and verify the maximum acceptable load for lifting and carrying (MAL-L&C) in single- and mixed-gender two-person teams. Participants lifted and carried a box 7.2 meters and placed it on a 132 cm high shelf, at rates of 1 x/min and 4 x/min. All male teams lifted and carried significantly (p<.05) more weight than all female teams or mixed-gender teams, and mixed-gender teams carried more than all female teams (p>.05). Our findings demonstrate that 1) individuals working alone or in teams can accurately estimate their ability to lift and carry loads for an hour, and that 2) when working in pairs, team MAL-L&C are approximately equal to the sum of their individual MAL-L&C. Percentile norms for MAL-L&CS are provided for male, female, and mixed gender teams.”

“Predictive models for team lifting capacity are important for task and equipment design, as well as worker selection and placement. The purpose of this study was to develop a prediction equation for single gender and mixed gender two-person team lifting from the floor to knuckle height. Men (n=23) and women (n=17) were combined into teams of two men (n=26), two women (n=24), and one man with one woman (n=25). Independent variables included incremental dynamic lift, 38 cm upright pull, dead lift, fat free mass, and body mass. A least squares linear regression was used. In addition, an equation was developed from deadlift strengths only. The lightest individual deadlift and the sum of the individual deadlifts were the best predictors of team lifting capacity (R{squared} = 0.90, SEE = 16). The results indicate that two-person team lifts to knuckle height are determined by the weaker team member.”

Rice, Valerie J., Sharp, Marilyn A., Williamson, Tania L. and Nindl, Bradley C. (1992): Effects of Gender, Lift Height, Direction, and Load on the Ability to Estimate Weight. In: Proceedings of the Human Factors Society 36th Annual Meeting 1992. pp. 669-673.
“The study evaluated the effects of gender, lift height, direction (lift/lower), and load on the ability to correctly estimate weight handled. Seven women and six men lifted and lowered boxes to and from knuckle, waist, and shoulder heights. Subjects were asked to estimate weights corresponding to 50, 40, 30, and 20% of gender specific lifting strength to 152 cm. The difference between the actual and estimated weight (DIFF) was 100% greater for men than for women (F = 6.27, p = 0.03). When the percent difference was analyzed, there was no significant gender effect. The least accurate estimates occurred when lowering a weight from knuckle height (p < 0.05). The majority of subjects underestimated the weight and men underestimated more frequently than women (Chi{squared} = 12.57, p = 0.0004). Subjects over-estimated the weight more often at higher weights. The results suggest that both men and women tend to underestimate weight, especially when lowering from knuckle height, possibly putting them at risk for injury.”
