Representations Of Argentine National Identity Via El Museo Nacional De Bellas Artes, Lindsay Newby
Representations Of Argentine National Identity Via El Museo Nacional De Bellas Artes, Lindsay Newby
Inquiry: The University of Arkansas Undergraduate Research Journal
National identity is a concept that every nation constructs and celebrates through the remembrance of important events or persons, the projection of literary works, and the erection of monuments. Yet, in order to truly understand a nation’s self-imagery, one must examine and chart all of its different periods through time. This allows one to avoid narrow, static definitions by viewing a nation in a more holistic sense. In this study, it is hypothesized that museums function to preserve, assert, and disseminate a sense of heritage and, in the case of the Museo Nacional de Bellas Artes, a sense of what …

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 …
Assessment Of The Modern Fish Assemblage In Mound Pond (Lonoke County) And Comparison With The Archeological Record, A. V. Fernando, M. A. Eggleton
Assessment Of The Modern Fish Assemblage In Mound Pond (Lonoke County) And Comparison With The Archeological Record, A. V. Fernando, M. A. Eggleton
Journal of the Arkansas Academy of Science
Mound Pound is a 56-ha oxbow lake of the Arkansas River. The lake has been disconnected from the Arkansas River main channel for over 2,500 years. The lake lies adjacent to the Toltec Mounds Archeological State Park, which contains the Toltec Mound Complex (3LN42). In October 2012, a multiple-gear sampling of the fish assemblage in Mound Pond was conducted using boat-mounted electrofishing, mini-fyke nets, and experimental gill nets. Across all gears, 501 fish specimens were collected and identified to species. Percent Similarity Index (PSI) and Shannon-Weiner Diversity Index (H') values were calculated using data from this survey and a previous …
Scarab Beetles (Coleoptera: Scarabaeidae) In The Dung Of Native Arkansas Mammals, J. B. Kelley, J. L. Hunt, M. B. Connior
Scarab Beetles (Coleoptera: Scarabaeidae) In The Dung Of Native Arkansas Mammals, J. B. Kelley, J. L. Hunt, M. B. Connior
Journal of the Arkansas Academy of Science
Dung beetles are important ecological components of natural ecosystems. One primary activity is the fragmentation and recycling of animal dung. Little is known about the ecological impact of beetles associated with the dung of mammals native to Arkansas. We surveyed the dung of native mammals within Arkansas to determine the species and distributional patterns associated with dung. We searched and collected beetles in situ from the dung or nests of native mammalian species within Arkansas. We also set simple pitfall traps using dung of various native Arkansas mammals as bait. Most of the beetles collected were common dung beetles. However, …

Trajectory Generation For Stair Ascent Walking Using Rayleigh Oscillator, T. Afzal, Andrew B. Wright, Kamran Iqbal
Trajectory Generation For Stair Ascent Walking Using Rayleigh Oscillator, T. Afzal, Andrew B. Wright, Kamran Iqbal
Journal of the Arkansas Academy of Science
This paper describes a trajectory generation technique for stair-ascent walking. The knee, hip and ankle joint trajectory during stair ascent are generated using mutually coupled, nonlinear oscillators. The parameters of the oscillators are tuned using the harmonic balance method, which converts the nonlinear differential equations to a set of algebraic equations. Fourier analysis of data generated by stair-ascent walking is performed to extract the amplitude and the phase of the dominant frequency components for each joint trajectory. The solution for the oscillator is assumed to be a sinusoidal wave and then by harmonic balance method the parameters of the oscillator …

New Distributional Records And Natural History Notes On Selected Fishes From Arkansas, Henry W. Robison, D. A. Neely, U. Thomas, Ken E. Shirley, J. K. Whalen, Chris T. Mcallister
Journal of the Arkansas Academy of Science
This report documents new records on the distribution of selected fishes from Arkansas and provides notes on their natural history. We document new geographic records for 21 species within 8 families in 12 counties of the state. Most importantly we have included new records for fishes ranked S1, S2 or S3 in the state by NatureServe and several Species of Special Concern by the Arkansas Game and Fish Commission (AGFC). Additional collections of fishes in the state will undoubtedly provide more records especially with the use of electroshocking devices as has been shown herein.

Short-Term Denitrification In The Metalimnion Of A Eutrophic Reservoir, Aki Kogo, Erin M. Grantz, Thad Scott
Short-Term Denitrification In The Metalimnion Of A Eutrophic Reservoir, Aki Kogo, Erin M. Grantz, Thad Scott
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Denitrification in metalimnetic water was examined under different conditions to determine how addition of nitrate (NO3 -) and particulate carbon (PC), aeration, and concentrations of nitrate affect denitrification. In the first experiment, water samples from a metalimnion were treated with different combinations of NO3 - and PC. Changes in excess N2 -N concentration for 10 days were measured using membrane inlet mass spectrometry (MIMS). The second experiment used the same treatments as the first experiment after aeration of water. Besides excess N2 -N concentrations, O2 concentrations were measured for 16 days. The third experiment examined how different initial concentrations of …
The Influence Of Poultry Litter Biochar On Early Season Cotton Growth, Taylor D. Coomer, David E. Longer, Derrick M. Oosterhuis, Dimitra A. Loka
The Influence Of Poultry Litter Biochar On Early Season Cotton Growth, Taylor D. Coomer, David E. Longer, Derrick M. Oosterhuis, Dimitra A. Loka
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Cotton is known for being sensitive to cool, wet soils, especially in the early stages of growth. Amendments to soil can aid cotton seedlings in development and nutrient uptake. However, soil amendments can be costly and detrimental to the environment, and alternatives such as the addition of biochar have been considered. Biochar is produced from biomass that has gone through pyrolysis and has been shown to improve plant yield, microbial response, soil structure, soil cation–exchange capacity, and water use efficiency. This study was conducted to evaluate the effect of biochar on early season cotton growth. The aim of this study …

Awareness, Use, And Perceptions Of Biodiesel: A Comparison Of Consumers In Belgium And The United States, Maggie Jo Pruitt, Leslie D. Edgar, Donald M. Johnson
Awareness, Use, And Perceptions Of Biodiesel: A Comparison Of Consumers In Belgium And The United States, Maggie Jo Pruitt, Leslie D. Edgar, Donald M. Johnson
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Belgian (N = 61) and American (N = 134) fuel consumers were interviewed in the summer of 2012 to determine their awareness, use, and perceptions of biodiesel. Consumers who were aware of biodiesel were asked their perceptions. A significantly P < 0.0001) higher percentage of Belgian consumers (78.7%) reported owning or driving a diesel vehicle compared to American consumers (9.0%). Belgian and American consumers moderately agreed biodiesel is a high-quality fuel. For both Belgian and American consumers, there was no significant association between owning a diesel vehicle and being aware of biodiesel or having purchased biodiesel. Although Belgian and American consumers agreed that using non-food crops for biodiesel is justified, Belgians were significantly less supportive than American consumers of using food crops for biodiesel. Both Belgian and American consumers disagreed with the statement “I would never use biodiesel”, and the two sets of consumers moderately disagreed that diesel engines would not run properly on biodiesel. Belgian and American consumers agreed that global warming is increasing; however, American consumers were more positive about the potential of biodiesel to reduce harmful exhaust emissions and global warming. Belgian consumers moderately agreed and American consumers agreed that biodiesel is better to use because it is made from renewable resources. Belgian and American consumers generally show similar perceptions of biodiesel, with the exception that American consumers were more positive toward the environmental and renewable aspects of biodiesel use. Recommendations for further research include gaining a better understanding of the potential positive influences that impact consumers’ perceptions of biodiesel.
Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Journal of the Arkansas Academy of Science
Spring-fed streams are abundant in karst topographic regions such as the Ozarks, providing an important and valuable water resource. Many of these spring-fed streams presently receive agriculture runoff, but few studies have examined the impacts of this runoff on water quality. We examined water quality in Ozark spring-fed streams surrounded by either agricultural (N=3) or primarily forested land (N=3) in the riparian zone. We hypothesized that agricultural sites would have greater dissolved nutrient concentrations and conductivity than forested sites and that water quality would fluctuate with distance from the spring source. Conductivity (p

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 …
Morphometric Analysis Of Dinosaur Tracks From Southwest Arkansas, R. Shell, Stephen K. Boss
Morphometric Analysis Of Dinosaur Tracks From Southwest Arkansas, R. Shell, Stephen K. Boss
Journal of the Arkansas Academy of Science
Dinosaur trackways were discovered in Cretaceous De Queen Limestone strata in Howard County, Arkansas, in June 2011. Multiple trackways with variably sized tridactyl tracks were exposed in a commercial quarry, suggesting multiple theropod species or adult and juvenile tracks of a single species. Results of morphometric analyses of 32 plaster casts from selected trackways are reported in an effort to identify the specific track-making dinosaurs and differentiate large and small tracks. Track measurements included length and width of each track, the lengths and widths of each digit impression, and the angular spread (divarication) between digit impressions. Twenty-nine plaster casts were …

Additional Vertebrate Records And Natural History Notes From Arkansas, M. B. Connior, C. Renn Tumlison, H. W. Robison, J. S. Placyk Jr., C. T. Mcallister
Journal of the Arkansas Academy of Science
Although vertebrates are a commonly studied group of animals, the distribution and natural history of many species within Arkansas is still not well understood or documented. However, recently several new distribution and natural history notes have been published in a continuing series regarding Arkansas’s vertebrates (e.g. Tumlison and Robison 2010; Connior et al. 2011, Connior et al. 2012). Thus, we continue to augment current literature with new records of distribution and provide notes on the natural history of selected vertebrates from Arkansas. All voucher specimens (physical or photographic) are deposited in the vertebrate collections at either Arkansas State University (ASUMZ), …
