A Demographic Approach To Race And Ethnicity In Metropolitan And Non-Metropolitan Regions Of Arkansas, 1990 And 1999, Todd W. Hodgson, Frank L. Farmer, Wayne P. Miller, Donald D. Voth

Research Reports and Research Bulletins

This manuscript provides an empirical portrait of emergent trends in the growth, distribution, and racial and ethnic composition of Arkansas’ resident population. Particular attention is given to variation in the racial and ethnic composition of the estimated population among different regions of the state. During the 1990’s, racial and ethnic diversity increased statewide due in large part to Hispanic population growth in all regions. Black population growth was greatest in central Arkansas while Asian and Native American population growth increased most rapidly in the northwest metropolitan regions of the state. Overall, both metropolitan and non-metropolitan Arkansas communities have a more …

Sulfur Amino Acid Requirements Of Broilers From Two To Five Weeks Of Age, Jill A. Townsend, H. R. (Trey) Pope, Jason L. Emmert Jan 2001

Sulfur Amino Acid Requirements Of Broilers From Two To Five Weeks Of Age, Jill A. Townsend, H. R. (Trey) Pope, Jason L. Emmert

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Phase-feeding (PF) in broiler chickens has been researched as a way to reduce feed costs without reducing growth performance and yield. Predicted amino acid requirements for PF are generated using linear regression equations derived from best estimates of lysine (Lys), sulfur amino acid (SAA), and threonine (Thr) requirements. During the late starter and early grower periods, predicted requirements for the SAA methionine (Met) and cysteine (Cys) are higher than levels recommended by the National Research Council (NRC), and previous research suggests that SAA may be lowered during the grower period without sacrificing growth performance or yield. The objective of this …

Development Of The Interactive Broiler Income Spreadsheet, Tara Shofner, H. L. Goodwin Jr. Jan 2001

Development Of The Interactive Broiler Income Spreadsheet, Tara Shofner, H. L. Goodwin Jr.

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The poultry industry has experienced unprecedented increased efficiencies since 1960 in large part due to vertical integration facilitated by production contracts between growers and integrators. As growers seek information about contract production they need to be well informed about all aspects of the process, especially potential income. Recent poultry grower complaints have surfaced as a result of incorrect expense and revenue expectations. The Interactive Broiler Income Spreadsheet (IBIS) is being developed to enable current and prospective poultry producers to better estimate income. IBIS, an unbiased Excel™ spreadsheet tool to assist in decision making regarding broiler production profitability, uses actual grower …

Vasotocin Receptor Expression In The Brain And Pituitary Gland During The Ovulatory Cycle Of The Fowl, Kelly Shaffer, Jorge A. Vizcarra, John Kirby Jan 2001

Vasotocin Receptor Expression In The Brain And Pituitary Gland During The Ovulatory Cycle Of The Fowl, Kelly Shaffer, Jorge A. Vizcarra, John Kirby

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Vasotocin receptors are members of seven transmembrane spanning G-protein associated receptors. Several isoforms have been recognized in mammals and birds. It has been shown that VT-1 expression occurs primarily in the brain while VT-2 expression occurs mainly in the pituitary. There is no current evidence to support that both VTR-1 and -2 are found in a single tissue. Our goal in this experiment was to see if VT-1 and VT-2 receptor mRNA expression varied in known sites of expression over the period of the ovulatory cycle of broiler breeder hens. In order to study potential changes in VT-1 and VT-2 …

Peripheral Blood Leukocyte Response And Macrophage Function During Eimeria Adenoeides Infection In Turkey Poults, Amanda D. Drake, Sarah E. Heuer, Timothy G. Kimball, Timothy O. Peters, H. David Chapman, Gisela F. Erf Jan 2001

Peripheral Blood Leukocyte Response And Macrophage Function During Eimeria Adenoeides Infection In Turkey Poults, Amanda D. Drake, Sarah E. Heuer, Timothy G. Kimball, Timothy O. Peters, H. David Chapman, Gisela F. Erf

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Intestinal coccidiosis, caused by various species of Eimeria, is an economically important disease of chickens and turkeys. The peripheral blood leukocyte response and macrophage functions during a coccidial infection in turkeys have not been defined. To examine these aspects of innate immunity during primary Eimeria infection in turkeys, 4-week-old poults were orally inoculated with either 50,000 E. adenoeides oocyst (24 infected poults) or water (24 control poults). To monitor the concentrations and proportions of white blood cells (WBC) throughout the course of infection, heparinized blood was collected from 12 infected and 12 control poults prior to inoculation (day 0), and …

The Possible Enzymatic Differences Between Cattle And Sheep In Their Response To Ergot Alkaloids, Susan M. Cannon, Charles F. Rosenkrans, Ali Moubarak Jan 2001

The Possible Enzymatic Differences Between Cattle And Sheep In Their Response To Ergot Alkaloids, Susan M. Cannon, Charles F. Rosenkrans, Ali Moubarak

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Ergotamine is an ergot alkaloid associated with fescue toxicosis of livestock who have grazed endophyte-infected fescue. High performance liquid chromatography (HPLC) was used to detect individual or species-specific differences in the metabolism of ergotamine by liver cytochrome P450 of sheep and cattle. Livers were collected from four steers and two sheep. The diet of the steers used in this study consisted of two being fed a grain diet, one steer grazing endophyte-infected fescue, and the final steer grazing endophyte-free fescue. The two lambs were both fed a grain diet. Livers were prepared and examined for the disappearance of ergotamine and …

Medicine And Health Care In Later Medieval Europe: Hospitals, Public Health,, And Minority Medical Practitioners In English And German Cities, 1250-1450, Anna Terry Jan 2001

Medicine And Health Care In Later Medieval Europe: Hospitals, Public Health,, And Minority Medical Practitioners In English And German Cities, 1250-1450, Anna Terry

Inquiry: The University of Arkansas Undergraduate Research Journal

Hospitals and individual caregivers helped meet the physical and psychological needs of medieval people, just as they do today. My overall objective is to explain social and individual responses to disease within the context of Christian theology and the urban community, focusing on England and Germany in the period between 1250 and 1450. First I investigate social responses to disease, including hospitals and public health ordinances. Christianity mandated the care of the afflicted, yet physical and mental illness was associated with sin and divine punishment. Urban authorities often attempted to deal with plague outbreaks by imposing quarantines and strict regulations …

When A Tree Falls In Fayetteville Does It Make A Sound: The Impact Of Issue Voting On Local Nonpartisan Elections, Jon Taylor Jan 2001

When A Tree Falls In Fayetteville Does It Make A Sound: The Impact Of Issue Voting On Local Nonpartisan Elections, Jon Taylor

Inquiry: The University of Arkansas Undergraduate Research Journal

This research provides an explanation of the impact that high-profile issues can have on local nonpartisan elections. The tree ordinance in Fayetteville sparked a controversy that ignited the community's interest in the race for Mayor. This controversy provides a unique opportunity to measure how issue voting effects elections that have limited information available. The research regarding behavior in local nonpartisan elections is incomplete, because of the challenges this subject provides for political scientist. It is difficult to gauge a voter's choice when the voter's process limited knowledge of the candidates and party affiliation is removed. Generally political scientist view issue …

Archaeology And The Public: Exploring Popular Misconceptions, Tamara Rakestraw, Amy Reynolds Jan 2001

Archaeology And The Public: Exploring Popular Misconceptions, Tamara Rakestraw, Amy Reynolds

Inquiry: The University of Arkansas Undergraduate Research Journal

To understand how the public views archaeology and uncover the sources of their perceptions, this paper summarizes the interviews of 58 Fayetteville area high school and college students from the Fall (2000). Using standard ethnographic techniques, including prepared questionnaires and open-ended conversation, we identified several trends in the public's perceptions of archaeology and have developed some hypotheses to account for them. As the Society for American Archaeology has only recently begun to understand, to better educate the general public about archaeology it is important to identify and understand the sources of these misconceptions. For more than a century, Hollywood, book …

Opposing Systems, Erin Stone Jan 2001

Opposing Systems, Erin Stone

Inquiry: The University of Arkansas Undergraduate Research Journal

Costa Rica and Nicaragua, although situated close together in geography, historically and politically are worlds apart. Costa Rica has maintained a stable democracy since 1948, while Nicaragua, rocked by authoritarian rule and then revolution in 1979, is still in an unstable growth period. Each country represents an opposing government system that would have varying effects on the emphasis and influence placed on different social situations in each country. Through studying one social aspect, the women's movement, one is able to examine the positive and negative aspects of each system and prospects for future success of countries under each type of …
