The Effect Of Handling Time On Temporal Discounting In Two New World Primates, Alexandra G. Rosati, Jeffrey R. Stevens, Marc D. Hauser

Center for Brain, Biology, and Behavior: Faculty Publications

Foraging decisions in nonhuman animals often require choosing between small, immediate food rewards and larger, more delayed rewards. Faced with such choices, animals typically discount or devalue the future quite strongly. Although discounting studies often focus on delays to reward access, other temporal intervals contribute to foraging rate, and thus may potentially influence discounting levels. Here, we examine the effect of handling time, the time required to process and consume food, on discounting in cottontop tamarins, Saguinus oedipus, and common marmosets, Callithrix jacchus, two species that differ in levels of temporal discounting. We presented subjects with a discounting task under …

Effect Of A Single Bout Of Prior Moderate Exercise On Cutaneous Perfusion In Type 2 Diabetes, Sheri R. Colberg, Henri K. Parson, Tanja Nunnold, D. Robb Holton, Aaron I. Vinik

Human Movement Studies & Special Education Faculty Publications

In diabetic individuals, increased shunting of circulation away from the skin may exist, contributing to their greater risk for ulcerations and poor cutaneous healing. In a prospective study (1), we previously found a lower skin perfusion during local heating in the foot dorsum of sedentary type 2 diabetic individuals compared with active people without diabetes. This defect was present despite normal increases in skin interstitial nitric oxide (NO), suggesting that NO is either ineffective or not involved (2). A prior bout of maximal exercise also lessened the impaired responsiveness to local heating of the dorsal foot in active type 2 …

Body Weight Penalties In The Physical Fitness Tests Of The Army, Air Force, And Navy, Paul M. Vanderburgh, Todd A. Crowder

Health and Sport Science Faculty Publications

Recent research has empirically documented a consistent penalty against heavier service members for events identical or similar to those in the physical fitness tests of the Army, Air Force, and Navy. These penalties, not related to body fatness, are based on biological scaling models and have a physiologic basis. Using hypothetical cases, we quantified the penalties for males, 60 vs. 90 kg body weight, and females, 45 vs. 75 kg, to be 15-20% for the fitness tests of these three services. Such penalties alone can adversely impact awards and promotions for heavier service members. To deal equitably with these penalties …

Accessibility Of Foreign-Flagged Cruise Ships: Does The Americans With Disabilities Act Stop At U. S. Shores?, Joseph H. Huber, J. U. Stein, J. L. Mackool

Movement Arts, Health Promotion and Leisure Studies Faculty Publications

This article examines the accessibility of foreign-flag cruise ships for disabled people under the Americans With Disabilities Act. The majority of cruise ships have foreign registrations, thus avoiding payment of U.S. taxes and compliance with U.S. labor regulations. In large part, this is due to the age-old practice that the nation registering the ship also governs internal affairs of the ship. However, foreign-flag cruise ships are required to comply with U.S. regulations governing mandatory sanitation inspections of food preservation and preparation, as well as emergency operations, including fire alarm systems and lifeboat drills.
