Acute Effects Of Exercise On Cognitive Performances Of Older Adults, R. Pennington, S. Hanna
Acute Effects Of Exercise On Cognitive Performances Of Older Adults, R. Pennington, S. Hanna
Journal of the Arkansas Academy of Science
Accelerating rates of structural decline become evident during the third and fourth decades of human life, with disproportionate degeneration occurring in the frontal, parietal, and temporal brain lobes. As the structure of the brain declines, a broad array of cognitive processes involving memory, decision making, and selective attention are reduced as well (Raz 2000, Park et al. 2001). Cardiovascular exercise has been associated with improved cognitive functioning in aging humans, suggesting that increased vascular supply enhances availability of oxygen, nutrients, and other physical entities to nourish the brain. Previous experimentation on older adults revealed significant positive effects of exercise on …
Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy
Eastern Spotted Skunk (Spilogale Putorius) At The Ouachita Mountains Biological Station, Polk County, Arkansas, L. M. Hardy
Journal of the Arkansas Academy of Science
A population of the eastern spotted skunk (Spilogale putorius) has been discovered at the Ouachita Mountains Biological Station in the Ouachita Mountains of Polk County, Arkansas. In 2010 a motion camera recorded a very brief infrared video of an animal that, after much study and conversation with other biologists, was concluded to be an eastern spotted skunk. Since that time the identification has been confirmed with at least 6 still photographs and one additional video that have been obtained from 2 other locations on the station. At least 2 or 3 individuals are present. All were photographed at night in …
Perch-Type Characteristics Of Overwintering Red-Tailed Hawks (Buteo Jamaicensis) And American Kestrels (Falco Sparverius), A. J. Worm, M. M. Bobowski, Thomas S. Risch
Perch-Type Characteristics Of Overwintering Red-Tailed Hawks (Buteo Jamaicensis) And American Kestrels (Falco Sparverius), A. J. Worm, M. M. Bobowski, Thomas S. Risch
Journal of the Arkansas Academy of Science
Red-tailed Hawks (Buteo jamaicensis) and American Kestrels (Falco sparverius) are primarily sitand-wait predators that rely on perches to forage most efficiently. Overwintering Red-tailed Hawks and American Kestrels use available perches (e.g., utility poles and wires, trees, fences, gates, etc.) to hunt for prey items in agricultural fields in northeast Arkansas. Observations were made from December 2011-March 2012 and November 2012-March 2013 in three representative cover-types (short rice stubble, soybean stubble, and fallow areas including roadsides) to determine which perch-types were used by Red-tailed Hawks and American Kestrels. Utility pole crossbeams at an average height of 6.3 m were the main …
Assessment Of Students’ Crisis Communications Skill Increase Based On Classroom Instruction And Second Life™ Training, Gregory C. Jernigan, Jessica R. England, Leslie D. Edgar
Assessment Of Students’ Crisis Communications Skill Increase Based On Classroom Instruction And Second Life™ Training, Gregory C. Jernigan, Jessica R. England, Leslie D. Edgar
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Crisis communication training and skill development are critical to ensure the sustainability of the agriculture industry. The purpose of this study was to assess students’ perceptions of knowledge, ability, and skills on select crisis-related skills, tasks, and activities in order to identify the potential effectiveness of a Second LifeTM (SL) simulation. Pre- and post-test data were collected to determine the potential changes in skill in the seven crisis communication constructs of (a) related knowledge; (b) mass, group, and intrapersonal communications; (c) contingency planning; (d) use of related supplies and tools; (e) identifying learning and training needs; (f) related areas of …
