Do Public Expenditures Improve Child Outcomes In The U.S.? A Comparison Across Fifty States, Kristen Harknett, Irwin Garfinkel, Jay Bainbridge, Timothy Smeeding
Do Public Expenditures Improve Child Outcomes In The U.S.? A Comparison Across Fifty States, Kristen Harknett, Irwin Garfinkel, Jay Bainbridge, Timothy Smeeding
Center for Policy Research
Our paper utilizes variation across the 50 U.S. states to examine the relationship between public expenditures on children and child outcomes. We find that public expenditures on children are related to better child outcomes across a wide range of indicators, including measures of child mortality, elementary-school test scores, and adolescent behavioral outcomes. States that spend more on children have better child outcomes even after taking into account potential confounding influences. Our results are robust to numerous variations in model specifications and to the inclusion of proxies for unobserved characteristics of states. Our sensitivity analyses suggest that the results we present …

Comparison Of Two Heifer Development Systems On A Commercial Nebraska Ranch, Tim Loy, Don C. Adams, Terry J. Klopfenstein, Dillon Feuz, Jacqueline A. Musgrave, Burke Teichert
Nebraska Beef Cattle Reports
A trial was conducted at a commercial Nebraska ranch to evaluate the effectiveness of a bred heifer development program that minimized the use of harvested feed. Two management systems were imposed on 505 March-calving bred heifers during the winter before the calving season, one including the use of hay (CON), and one relying solely on winter range and supplementation (TRT). During the winter period, heifers in the TRT system lost less condition and had similar weight gains to CON. Two-year-old pregnancy rates did not differ between systems. A partial budget analysis of the two development programs indicated that the TRT …
Resistant Rice Starch Development, Siow Ying Tan
Resistant Rice Starch Development, Siow Ying Tan
LSU Master's Theses
This study showed that enzyme treatments were effective in producing resistant starch from rice flour and starch. Rice starch produced higher resistant starch yields than rice flour. The lower resistant starch yields in rice flour could be attributed to the presence of lipids and proteins which were competitively binding to amylose, resulting in decreased recrystallization of amylose. The gelatinization type and incubation periods were not as influential as enzyme treatments in the resistant starch formation. The rapid visco amylograph (RVA) analysis indicated that the gelatinized samples have minimal pasting characteristics since they had been gelatinized prior to enzyme treatments. Pasting …
Potential Functionality And Digestibility Of Oryzanol As Determined Using In Vitro Cell Culture Models, Chih-Chun Jean Huang
Potential Functionality And Digestibility Of Oryzanol As Determined Using In Vitro Cell Culture Models, Chih-Chun Jean Huang
LSU Doctoral Dissertations
A mouse lymphatic endothelial cell (SVEC4-10) model and a human intestinal cell (C2BBe1) model in vitro were developed and capable to be used to study antioxidant activity, hypocholesterolemic capability and digestibility of γ-oryzanol. The critical and vital parameters in developing these cell models were the emulsion preparation of hydrophobic compounds for cell models, the consistent management of cell culture, and the selection of cell viability detection methods compatible with the cell lines and the test substances. The results showed that, in some situations, γ-oryzanol could present a more effective antioxidant activity than α-tocopherol, in terms of reducing tert-butyl hydroperoxide promoted …

Bombarding The City Of The Dead: Who Has A Right To The Past?, Corey David Hotard
LSU Master's Theses
This study focuses on the relationship between tourism and archaeology at Saint Louis Cemetery Number One in New Orleans. In the past two decades, the discipline of archaeology has been thrust into the gaze of the public. The Information Age has led to the increased accessibility of archaeological sites to anyone who may have an interest. Due to this increased accessibility, professional archaeologists have turned to public archaeology in order to satiate the public’s curiosity. Although public archaeology is a growing field, a good bit of the subject still deals mainly with legislation and preservation rather than direct contact with …

Genetic Mapping Of Agronomic Traits From The Interspecific Cross Of Oryza Sativa (L.) And Oryza Glaberrima (Steud.), Gabriel Kayode Aluko
LSU Doctoral Dissertations
Wild relatives of cultivated rice varieties offer new genetic sources for enhancing economic value, but traditional interval mapping techniques have not gained widespread support among applied researchers for marker assisted selection. The objectives of this study were to detect quantitative trait loci (QTL) for agronomic traits in a hybrid mapping population and compare the non-parametric Discriminant Analysis (DA) procedure with traditional approaches for accuracy and precision. In addition, the effects of population structure on marker-assisted classification were explored. A molecular linkage map comprising 100 SSR markers that spanned the rice genome at intervals of 10.5 cM on the average was …
"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle
"Baleful Weeds And Precious-Juiced Flowers": Romeo And Juliet And Renaissance Medical Discourse, Erica Nicole Daigle
LSU Master's Theses
This thesis claims that Shakespeare exaggerated the characterization of two figures in Romeo and Juliet, Friar Laurence and the apothecary, to make a statement about the conditions of medical treatment in sixteenth century London. These two figures represent two very different approaches to healing, one that is informed with ancient holistic medical theory and one that is driven by economics, and this work attempts to explain the cultural conditions that warranted such a discrepancy in the play. I address these two medical figures in the contexts of the events of the text, of the contemporary medical profession, and of materialism …

The Determination Of Appropriate Phosphogypsum: Class C Fly Ash : Portland Type Ii Cement Compositions For Use In Marine Applications, Pradyot Sudhakar Deshpande
LSU Master's Theses
Phosphogypsum (PG, CaSO4·2H2O) is a waste by-product produced during the wet manufacturing phosphoric acid process. Phosphoric acid is manufactured by processing phosphate rock that contains relatively high concentrations of naturally occurring radioactive impurities which makes PG a radioactive material. PG also contains certain trace metals including As, Ba, Cd, Cr and Pb and radioactive contaminants such as Radium226 and Uranium238 that pose potential hazard to human health and the environment. According to USEPA, the current allowable disposal method for PG is stack piling. This research was focused on stabilizing PG with Portland Type II …

Evaluation Of Fertilizer And Irrigation Production Systems For Large Nursery Containers, Anthony Lynn Witcher
LSU Master's Theses
Container-grown woody ornamentals require high volumes of water and sufficient nutrients to develop into healthy, high quality plants. The increased awareness of possible contamination of ground and surface water resources from nursery runoff has forced growers to implement higher water use efficiency techniques to maximize fertilizer efficiency and reduce nutrient and irrigation runoff. Components of a large container production system that could affect irrigation volume, substrate nutrition levels and runoff include fertilizer placement, irrigation frequency and irrigation method. Irrigation and fertilization components were evaluated in two experiments to determine which would maximize growth, minimize effluent and reduce the amount of …

Characteristics Of Fat Free Yogurt As Influenced By The Incorporation Of Folic Acid, Charles August Boeneke
LSU Doctoral Dissertations
Folic acid fortification is used in the prevention of neural tube defects such as spina bifida and ancencephaly, heart defects, facial clefts, urinary tract abnormalities, and limb deficiencies. Although yogurt is not a good source of folic acid, fortification could aid in prevention of above mentioned defects. Fortification of yogurt with folic acid may or may not change its physico-chemical characteristics. Fat free sugar free yogurt was manufactured using 0, 25%, 50%, 75% and 100% of the recommended daily allowance of 400 micrograms of folic acid. Treatments included addition of folic acid at these levels before and after pasteurization. Lemon …

Random Centroid Optimization Of Lutein-Enriched Oil In Water Emulsion At Acidic Ph, Armen Khachatryan
LSU Master's Theses
Age-related macular degeneration (AMD) is a physiological condition that affects the elderly, diabetic patients, and leads to loss of vision. There are no effective therapies for AMD. The role of nutrition in preventing AMD is receiving strong scientific scrutiny. Lutein and zeaxanthin have been identified as dietary strategies that can delay the onset of AMD. Consumption of at least six milligrams of lutein per day has been reported to delay the onset of AMD by as much as 43%. However, most available food sources contain such low levels of lutein that it would be difficult to meet the daily requirement. …

Using Trabecular Architecture Of The Proximal Femur To Determine Age At Death: An Accuracy Test Of Two Methods, Wendy Michelle Jones
LSU Master's Theses
Osteologists and forensic researchers are often called upon to determine age at death for skeletal remains. Although there are common methods in wide use, new methods are always sought. This study evaluates the accuracy of two radiographic methods of determining age by looking at the changes in the trabecular architecture of the proximal femur. These two methods are the Szilvassy and Kritscher (1990) method and the Walker and Lovejoy (1985) method. Samples were taken from four skeletal collections. Radiographs were taken of each individual and both Szilvassy and Kritscher’s (1990) phases of trabecular change and Walker and Lovejoy’s (1985) phases …

Immunological, Hematological, And Serum Biochemical Effects Of High Level Dietary Fish Oil And Vitamin E Supplementation In The Dog, Casey J. Leblanc
LSU Doctoral Dissertations
Inflammation is a component of the innate immune response. However, severe or prolonged inflammation can be detrimental. Dietary n-3 fatty acid supplementation has proven clinical benefits in chronic inflammatory diseases, most likely due to reduced synthesis of inflammatory mediators and inhibition of lymphocyte proliferation and function. The purposes of this study were to characterize alterations in inflammatory mediator production, and lymphocyte proliferation, in dogs fed a diet consisting of 0.65% n-3 fatty acids (DMB) with an n-6:n-3 fatty acid ratio of 3.4:1. Fifteen dogs were randomly assigned to one of three dietary groups for twelve weeks. Group Sunflower oil received …

The Effects Of Intra-Articular Silicone Polymer On Synovial Fluid, Synovial Tissue, And Articular Cartilage In The Equine Middle Carpal Joint, Marilyn Rumbaugh
LSU Master's Theses
There is anecdotal documentation that intra-articular administration of liquid silicone is used as a lubricant for equine joints. Effects of silicone polymer on equine articular cartilage and synovial fluid have not been evaluated. The objectives were to characterize the effects of intra-articular administration of liquid silicone polymer on clinical, synovial fluid, and microscopic features in normal middle carpal joints of horses, and to determine if silicone migrates to the axillary lymph nodes. Eight adult horses were used in this study. Two mLs of 1,000 centistoke, medical-grade silicone was injected into one randomly selected middle carpal joint. The opposite middle carpal …
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
Six-Month Follow-Up Of A Primary Care Managed Weight Loss Program For Overweight And Obese African-American Women, Lee A. Marsh
LSU Master's Theses
Obesity is the number one public health concern in the United States, and is more prevalent in African-American women and those from lower socioeconomic groups. However, many primary care physicians do not feel confident in their ability to assist patients in weight management. Thus the challenge for physicians is to provide patients better assistance with weight management. The purpose of the study was to examine the efficacy of a primary care-managed weight loss program on weight reduction and cardiovascular fitness in overweight/obese women. Participants were randomized to intervention (n=54; Age: 44+12 yrs) or standard care (n=62; Age: 44=12yrs) and followed …
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
The Effect Of Aging On The Immune Response To Vaccination In The Horse, Daniel H. Fermaglich
LSU Master's Theses
Vaccination programs are designed to protect an animal from infection, however, depending upon the age and health of the animal vaccination may not stimulate a protective humoral response. It is possible that, as in the human and mouse models, geriatric equines may be less responsive than their younger counterparts to current vaccination protocols. The purpose of this study was to identify an age related diminution in the primary and secondary immune responses of geriatric horses in response to vaccination. Two groups of horses were sampled. The first group consisted of an open herd of 39 privately owned horses, varying in …
Psychosocial Predictors Of Visceral Adiposity, Paula C. Rhode
Psychosocial Predictors Of Visceral Adiposity, Paula C. Rhode
LSU Doctoral Dissertations
Psychosocial factors are thought to influence health through primarily direct physiological mechanisms or the alteration of health related behaviors. Three factors hypothesized to negatively impact health include arousal, life stress, and depressive symptomatology. One recent theorist suggests that the interaction between psychological stress and stress hormones on the neuroendocrine system may result in adverse changes to body composition, most notably the increased deposition of visceral adipose tissue (Bjorntorp, 1993). The current study prospectively examined the relationship between self-reported stressful life events, depressive symptoms and trait arousal on the deposition of visceral fat, as measured by computerized tomography (CT). Subjects were …

Proportional Assessment Of X And Y Chromosome-Bearing Spermatozoa In Bull And Boar Ejaculates Using Conventional And Real-Time Pcr Techniques, Julius Braden Paul
LSU Doctoral Dissertations
Considerable variation in the percentage of Y-chromosome bearing spermatozoa (%Y-CBS) between ejaculates in the same male has been reported. Collection regime has been speculated to influence the degree of variation in %Y-CBS in bull ejaculates (Chandler et al., 1998). Experiments were designed to evaluate the effects of two collection regimes on %Y-CBS. Conventional PCR combined with gel electrophoresis and image analysis was employed to determine %Y-CBS in ejaculates from two bulls collected on 7-day intervals and two bulls on 21-day intervals. Real-time PCR technology was used to quantify %Y-CBS in the same ejaculates. Boar ejaculates were also analyzed with both …

Mediators Of Weight Loss In An Internet-Based Intervention For African American Adolescent Girls, Marney A. White
LSU Doctoral Dissertations
The primary aim of this study was to assess the process variables involved in a weight loss program for African-American adolescent girls. This internet-based intervention compared a behavioral treatment program to an educational treatment program; it was hypothesized that participants randomized to the behavioral condition would lose more weight at 6 months than those in the educational condition. Several process variables have been identified as affecting success in in vivo weight loss programs for adults and children, including program adherence, self-efficacy, and social support. The current study sought to broaden the understanding of these process variables as they pertain to …

Optimization And Automation Of A Thermal Oyster Shucking Process, Daniel Edgar Martin
LSU Doctoral Dissertations
Louisiana Gulf Coast oysters (Crassostrea virginica) were subjected to thermal shucking treatments to effect adductor muscle release from both left and right valves. The oysters were instrumented with thermocouples to monitor and record process temperatures in the oysters and on the shell. Following treatment, the oysters were evaluated for relaxation and release of the adductor muscle, meat quality and texture, and for the effect of the treatments on the storage life of the oysters as measured by total microbial plate counts. The treatments of many oysters resulted in a complete release of the adductor muscle from the shell while maintaining …
