Effect Of Social Status Of Dairy Heifers On Expression Of Estrus And Subsequent Fertility, Dawn A. Elkins, Rick W. Rorie
Effect Of Social Status Of Dairy Heifers On Expression Of Estrus And Subsequent Fertility, Dawn A. Elkins, Rick W. Rorie
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A study was conducted to determine if social status of heifers within a herd influences estrus activity and subsequent fertility. Thirty cyclic dairy heifers were observed over a 14 d period and ranked by social status, based on a displacement index. The estrous cycles of the heifers were synchronized by treatment with two injections of prostaglandin F2a (PGF2a; Lutalyse, 25 mg) given 14 d apart. At the second PGF2a injection, HeatWatch transmitters were placed on the heifers for continuous monitoring of mounting (estrus) activity over the next 45 d. All heifers were artificially inseminated at estrus, using semen from a …
Integrating Supervised And Unsupervised Classification Methods To Develop A More Accurate Land Cover Classification, Donald I.M. Enderle, Robert C. Weih Jr.
Integrating Supervised And Unsupervised Classification Methods To Develop A More Accurate Land Cover Classification, Donald I.M. Enderle, Robert C. Weih Jr.
Journal of the Arkansas Academy of Science
The classification and mapping of land cover provides fundamental information about the characteristics, activities, and status of specific areas on the earth's surface. The quality of the final classification is critical in providing accurate information for ecologists and resource managers in decision-making and for developing a landscape-level understanding of an ecosystem. A land cover classification was developed for 5 research watersheds in Garland and Saline counties in Arkansas using 2002 LANDSAT7 Enhanced Thematic Mapper Plus (ETM+) satellite imagery. The supervised classification was based upon 146 training areas identified from reference data and then applied to the imagery using the maximum …
Cognitive Vulnerability In Anxiety, Emotional Dysregulation, And Bulimia Nervosa, Rachael Motley
Cognitive Vulnerability In Anxiety, Emotional Dysregulation, And Bulimia Nervosa, Rachael Motley
Inquiry: The University of Arkansas Undergraduate Research Journal
Bulimia Nervosa (BN) is an eating disorder that is characterized by recurrent cycles of binge eating and compensatory behaviors (e.g. purging). Individuals suffering from BN usually report feeling anxious or depressed before the onset of their eating problems, and disordered eating may represent an attempt to cope with negative emotion. The anxiety associated with BN may arise from several pathways including body dissatisfaction, idealized images of thinness, and negative life events (Polivy & Herman, 2002). There are also other factors that contribute to the development of BN including difficulties with emotion regulation (e.g. alexithymia). We propose that certain individuals are …
From Truck Bed To Bare Feet: The Anthropology Of Tourism, Lee Ballard
From Truck Bed To Bare Feet: The Anthropology Of Tourism, Lee Ballard
Inquiry: The University of Arkansas Undergraduate Research Journal
In the summer of 2004, three companions and I set out on an adventure after a month of archaeology work in the northwest jungles of Belize. This essay is not only a loose account of some exploits and misadventures, but it also illustrates how the tourism industry has affected this region. Through my experiences I was able to create a dichotomy of two contrasting countries, Belize and Guatemala, in order to convey how tourism can affect the culture and structure of different societies. Here I present a portrait of how socio-economic changes, complex acculturation, and changes in environmental stability have …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The frequent outbreaks of food-borne illness necessitate development of intervention strategies, including the use of natural antimicrobials. Listeria monocytogenes is one of the most important bacterial pathogens that recently has caused a significant number of outbreaks. With the aim of finding potent natural agents that can minimize pathogen contamination concerns, this study evaluated the inhibitory activities against L. monocytogenes of grape seed extract (GSE), malic acid (M), nisin (N), and combinations thereof incorporated into soy-protein edible films. Soyprotein films with/without addition of antimicrobial agents (GSE: 1%, Nisin: 10,000 IU/g, Malic acid: 1%, and their combinations) were prepared and evaluated for …

Level And Source Of Supplemental Selenium For Beef Steers, Scott Fry, Elizabeth B. Kegley, M. Ellen Davis, Michael D. Ratcliff, Douglas L. Galloway, Ron A. Dvorak
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Selenium (Se) is deficient in many Arkansas soils; therefore, an experiment was conducted on steers to evaluate the effects of two supplemental Se sources on performance, blood metabolites, and immune function. Thirty Angus-crossbred steers were blocked by weight and assigned within block to one of 15 pens (two steers/pen). Pens were assigned randomly within blocks to one of three dietary treatments consisting of a corn-soybean meal supplement devoid of supplemental Se (negative control, NC) or corn-soybean meal supplements providing 1.7 mg supplemental Se/d as sodium selenite (inorganic Se, ISe) or as Se yeast (organic Se, OSe). Steers were offered fescue …

A Study Of The Civil Justice Reform Act Of 2003: Can Tort Reform Benefit Arkansas?, Scott Jackson
A Study Of The Civil Justice Reform Act Of 2003: Can Tort Reform Benefit Arkansas?, Scott Jackson
Inquiry: The University of Arkansas Undergraduate Research Journal
Without question, reforming America's civil justice system has become a hot button issue in today's political landscape. While most Americans move about their daily lives without giving the subject a second thought, politicians ranging from aspiring state assemblymen to the recently reelected George W Bush have placed tort reform at the forefront of American political affairs. Although problems plaguing American courts have been discussed for years, criticism of America's current system for adjudicating tort cases has reached a fever pitch. Among the more vocal critics are powerful lobbyist groups, such as the American Medical Association (AMA) and the American Tort …
The Electoral Consequences Of Neoliberal Reform Explaining Voter Turnout In Latin America's Dual Transition Era, R. Ryan Younger
The Electoral Consequences Of Neoliberal Reform Explaining Voter Turnout In Latin America's Dual Transition Era, R. Ryan Younger
Inquiry: The University of Arkansas Undergraduate Research Journal
Voter turnout has declined precipitously during Latin America's 25 year experience with representative democracy. This decline has occurred in conjunction with another important trend. Across the region, economic development directed by state leaders and characterized by heavy state intervention has been replaced by a development model, commonly referred to as the Washington Consensus, in which markets are the preferred instrument for growth and the state plays a minimal role. This means that as people were casting off their undemocratic past, their economies were also undergoing fundamental change. This simultaneous turn to democratic governments and marketbased economic policy is commonly called …
