Attack Of The Balloon People, Keith E. Sealing Jan 2007

Attack Of The Balloon People, Keith E. Sealing

Vanderbilt Journal of Transnational Law

Any discussion of food security would, at first blush, seem to focus primarily on world hunger and other threats to the safety of the food supply, whether intentionally man-made (e.g., terrorism), inadvertently man-made (e.g., global warming), made-for-profit by industrial agriculture (referred to as "industrial food" throughout this Article), or "natural" although arguably man-abetted (such as bovine spongiform encephalopathy, or mad cow disease). And hunger is indeed a problem and likely to become more of a problem. However, this Article focuses on the long term threat to world health and world food security caused by the American way of eating; the …


Fast Food: Regulating Emergency Food Aid In Sudden-Impact Disasters, David Fisher Jan 2007

Fast Food: Regulating Emergency Food Aid In Sudden-Impact Disasters, David Fisher

Vanderbilt Journal of Transnational Law

A rich and varied literature has grown up around food aid,' in particular with regard to its use as a development tool, in response to slow-onset disasters (such as droughts and desertification), and in armed conflicts. Given that these applications make up the bulk of the millions of tons of food aid recorded annually and present some of the thorniest operational issues, perhaps it is not surprising that the regulation of food aid provided in sudden-impact disasters (such as earthquakes, tsunamis, wind storms, and floods) has not been as thoroughly examined.

Still, while the amount of food involved is comparatively …


Senate Bill (Sb) 172: Governance Of Nutrition In Kentucky Public Schools: Implementation Analysis Final Report, Bill Brumbach Jan 2007

Senate Bill (Sb) 172: Governance Of Nutrition In Kentucky Public Schools: Implementation Analysis Final Report, Bill Brumbach

MPA/MPP/MPFM Capstone Projects

This report is intended to evaluate the implementation of Senate Bill (SB) 172 in Kentucky's public schools. This law requires that all schools in Kentucky implement strict nutrition standards that apply to all foods sold during the school day. This report highlights the different methods used by selected schools in implementing the requirements in SB 172. In performing my analysis, I traveled to different schools in central and southeastern Kentucky to assess how these select schools were meeting the requirements of the law. Site visits allowed me to discuss implementation strategies with school administrators and aided in my understanding of …


Public Provision Of Service For The Elderly: An Empirical Analysis Of County-Level Senior Service Property Tax Levies, Brigitte Blom Ramsey Jan 2007

Public Provision Of Service For The Elderly: An Empirical Analysis Of County-Level Senior Service Property Tax Levies, Brigitte Blom Ramsey

MPA/MPP/MPFM Capstone Projects

Last year the baby boom generation began turning 60. Consequently, the number of senior citizens is expected to double by the year 2030. On average, a person reaching the age of 60 can expect to live an additional 22 years. (NCHS, 2003) Along with increased life expectancy comes a greater probability for chronic illness, physical impairment and loss of independence. Of those 85 and older, 55% will need some type of long-term care or personal assistance. (CBO, 2004)

A recent collaborative study, “The Maturing of America: Getting Communities on Track for an Aging Population”, notes that less than half of …

Cadaver Decomposition In Terrestrial Ecosystems, David O. Carter, David Yellowlees, Mark Tibbett Jan 2007

Cadaver Decomposition In Terrestrial Ecosystems, David O. Carter, David Yellowlees, Mark Tibbett

Department of Entomology: Faculty Publications

A dead mammal (i.e. cadaver) is a high quality resource (narrow carbon:nitrogen ratio, high water content) that releases an intense, localized pulse of carbon and nutrients into the soil upon decomposition. Despite the fact that as much as 5,000 kg of cadaver can be introduced to a square kilometer of terrestrial ecosystem each year, cadaver decomposition remains a neglected microsere. Here we review the processes associated with the introduction of cadaver-derived carbon and nutrients into soil from forensic and ecological settings to show that cadaver decomposition can have a greater, albeit localized, effect on below-ground ecology than plant and fecal …


Nanoparticle Mediated Oral Delivery Of Insulin, Etienne Cabane Jan 2007

Nanoparticle Mediated Oral Delivery Of Insulin, Etienne Cabane

Master's Theses and Capstones

The oral delivery of therapeutic compounds, from small molecules to proteins, is one of the most desirable routes of administration. Its advantages reside in low cost, patient compliance and ease of use. The major challenge associated to such a delivery route is the transport through the gastrointestinal tract (GIT). In the case of complex and fragile molecules such as proteins, this particular step is the source of multiple challenges. Among the approaches developed to protect the therapeutic compound, the use of polymeric carriers is the most promising. We developed biocompatible and biodegradable polymersomes formed by the self assembly of amphiphilic …

Promoting Resilience In Inner City Youth : Implications For Counselors, Anthony D. Lymus Jan 2007

Promoting Resilience In Inner City Youth : Implications For Counselors, Anthony D. Lymus

Graduate Research Papers

The strain and difficulties that plague the inner city continue to mount. As a result, youth who grow up in this environment are exposed to violence, substance abuse, inadequate education, and poverty. Although some youth become a part of the cycle that produces these unfortunate events, some are able to make it out and become assets to society. This occurrence has been termed resilience. The study of resilience continues to grow as researchers attempt to provide information for school officials, communities, and mental health practitioners about how to promote resilience in inner city youth.


Breast-Fed Low Birth Weight Premature Infants: A Description Of Nutritional Intake In The First Six Months Of Life, Ksenia Zukowsky Jan 2007

Selected Works of Ksenia Zukowsky, CRNP, PhD

This is a secondary analysis of a larger project entitled "Breast-feeding Services for LBW Infants-Outcomes and Costs" (L. Brown, RN, Ph.D., Principal Investigator), funded by NINR at NIH, (NR 03881). The larger project was a randomized clinical trial, of women planning to breast-feed their LBW infant. The control group received routine breast-feeding care and an intervention group received a structured program of breast-feeding services provided by an advanced practice nurse.

Healthy premature LBW infants from the control group were selected as subjects for this secondary analysis. One question of this secondary analysis was to describe the nutrition of healthy premature …


Corporations And Commercial Speech, Ronald Collins, Mark Lopez, Tamara Piety, David C. Vladeck Jan 2007

Corporations And Commercial Speech, Ronald Collins, Mark Lopez, Tamara Piety, David C. Vladeck

Georgetown Law Faculty Publications and Other Works

Even though we are discussing a case that was not decided on the merits, Nike v. Kasky is an important case because it crystallizes two of the essential critiques about the commercial speech doctrine, critiques that have run through this doctrine from before its advent in 1976 to today. The fundamental debate Nike triggered over what constitutes "commercial speech" and how strictly commercial speech should be regulated is still being played out - not just in the academy, but also in the courts on a day-to-day basis. So this is a timely and important topic.

Serum Gamma-Glutamyltransferase And The Risk Of Type 2 Diabetes In A Population-Based Cohort Study Of Older Mexican Americans, Lynn Blythe Jan 2007

Serum Gamma-Glutamyltransferase And The Risk Of Type 2 Diabetes In A Population-Based Cohort Study Of Older Mexican Americans, Lynn Blythe

Master's Theses and Doctoral Dissertations

Our objective was to test the hypothesis that increased GGT predicts an increased risk of type 2 diabetes (T2D) in elderly Mexican Americans.

Data from a population-based cohort study of 1789 community-dwelling Mexican American men and women, aged 60-101, in the SALSA study were used. Data for 1,203 participants without diabetes at baseline were evaluated for incident diabetes. Proportional hazard models were used to predict the probability of incident T2D by GGT level.

After adjustment for age, gender, smoking, alcohol use, and BMI, the risk of developing T2D associated with GGT was significant at 1.4 (95% CI 1.2 -1.7). However, …

Effective Approaches To Minimize The Problem Of Pharmaceuticals And Other Personal Care Products In The Environment, Papun Pramanick Jan 2007

Effective Approaches To Minimize The Problem Of Pharmaceuticals And Other Personal Care Products In The Environment, Papun Pramanick

Theses

Studies have shown that pharmaceuticals and other personal care products (PPCPs) are present in the environment, especially in water, due to different human activities. Some of these compounds are toxic to our eco-system. Although there is no evidence of adverse human health effect from the presence of PPCPs in the environment to date , some adverse effects on aquatic life cycle already have been found. Therefore, protecting our environment as well as human health from adverse effect(s) of PPCPs is a growing concern. The objective of this thesis work was to collect information about the principal approaches available to pharmaceutical …


Ready Or Not, Here They Come : A Look At Kindergarten Readiness, Sara J. Swyter Jan 2007

Ready Or Not, Here They Come : A Look At Kindergarten Readiness, Sara J. Swyter

Graduate Research Papers

This study examined the subject of kindergarten readiness. Both socially and academically mature and immature children were included in this study. An intervention model was presented for children who assessed behind their peers socially and academically. It was documented and reported that children who were assessed as below their peers socially and academically were able to make good progress through the intense one-on-one interventions performed; however, their growth was not enough to completely catch them up to their non-struggling peers. Results were shared and recommendations were made for future children academically and socially immature.

The Development And Molecular Expression In Mammalian Cells Of An Ha-Tagged Plasmid Encoding For The Target Of Rapamycin (Mtor), Kevin S. Dougherty

Browse all Theses and Dissertations

The protein kinase mammalian Target of Rapamycin (mTOR) is a master controller of cell growth and proliferation due to its ability to integrate growth signals and regulate translation through 4E-BP1 and p70-S6K. We developed four phCMV2-HA-tagged plasmids to overexpress TOR in mammalian cells: Wild Type, D2357E (Kinase Dead), R2109A (PA Binding Deficient) and, S2035T (Rapamycin Resistant) each verified by restriction enzyme digestion and direct sequencing. Plasmid DNA was overexpressed in COS-7 cells and the 289 kDa protein detected in Western blots developed with anti-HA and anti-mTOR antibodies. Kinase activity of the overexpressed protein was detected by in vitro phosphorylation of …

Color, Cooking Loss And Textural Properties Of Patties As Affected By Catfish Belly Flap Mince Size And Cooking Method, Jin M. Kim, Bartholomew Green Jan 2007

Color, Cooking Loss And Textural Properties Of Patties As Affected By Catfish Belly Flap Mince Size And Cooking Method, Jin M. Kim, Bartholomew Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Patties were prepared with different sizes of channel catfish belly flap mince. Belly flap meat was minced using four different sizes of openings of plate, mixed with salt, formed, and cooked by two methods, in water and oven. Results indicated no differences (p > 0.05) in Kramer shear break force in the patties cooked by different methods for the same size of mince. As the size of meat particles for patties decreased, hardness and gumminess increased, and color differed from fillet, but Kramer shear break force as well as percent cooking loss decreased (p < 0.05). Patties cooked in an oven showed greater color difference from fillet, percent cooking loss, hardness, and gumminess than those cooked in water for the same size of meat particles (p < 0.05). doi: 10. 1300/J030v 16nO 1_03 [Article copies available for a fee from The Haworth Document Delivery Service: 1-800-HA WORTH.

Adrenomedullin (Am) And Adrenomedullin Binding Protein (Am-Bp) In The Bovine Mammary Gland And Milk: Effects Of Stage Of Lactation And Experimental Intramammary E. Coli Infection, Ted H. Elsasser, Anthony V. Capuco, Thomas J. Caperna, Alfredo Martínez, Frank Cuttitta, Stanislaw Kahl

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Adrenomedullin (AM) has been characterized as an endogenous tissue survival factor and modulator of many inflammatory processes. Because of the increased susceptibility of the mammary gland to infection during the time surrounding parturition in the cow, we investigated how milk and tissue content of AM and its binding protein (AM-BP) might be affected by the stage of lactation and the udder health status. Milk and mammary biopsy samples were obtained from Holstein cows 21 days prior to and at various times after calving to represent the dry period and early and midstages of lactation. Additional cows received an intramammary challenge …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We investigated proteomic and genomic profiles of glycinin, a family of major storage proteins in 16 different soybean genotypes consisting of four groups including wild soybean (Glycine soja), unimproved cultivated soybean landraces from Asia (G. max), ancestors of N. American soybean (G. max), and modern soybean (G. max) genotypes. We observed considerable variation in all five glycinin subunits, G1, G2 G3, G4 and G5 using proteomics and genetic analysis. Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry (MS) analysis showed that the wild genotypes had a range of 25-29 glycinin protein spots that included …


Characterization Of Biological Types Of Cattle (Cycle Vii): Influence Of Postpartum Interval And Estrous Cycle Length On Fertility, R. A. Cushman, M. F. Allan, R. M. Thallman, L. V. Cundiff Jan 2007

Characterization Of Biological Types Of Cattle (Cycle Vii): Influence Of Postpartum Interval And Estrous Cycle Length On Fertility, R. A. Cushman, M. F. Allan, R. M. Thallman, L. V. Cundiff

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Genetic improvement in reproductive efficiency through selection is difficult because many reproductive traits are binomial and have low heritabilities. Before genetic markers can be generated for fertility in cows, greater characterization of reproductive phenotypes is needed to understand the components of the trait. The current study tested the hypotheses that: 1) breeds vary in postpartum interval to estrus (PPIE) and estrous cycle length, 2) a longer estrous cycle immediately before breeding increased pregnancy rates, and 3) a greater number of cycles before breeding increased conception rates. The postpartum interval to estrus, estrous cycle length, and number of cycles before breeding …
