Modelling The Impact Of National Development Strategies For The East African Rice Sector, Florence Muthee
Graduate Theses and Dissertations
The 2008 food crisis prompted many food importing nations to reconsider the need to be self-sufficient especially in their staple food needs. This awakening led to the launch of the Coalition for Africa Rice Development (CARD) initiative with a goal to double rice production in Africa. Under the CARD umbrella member countries drafted individual National Rice Development Strategies (NRDS). This study is a quantitative assessment of four East African countries’ NRDS: Kenya, Rwanda, Tanzania and Uganda within dynamic global rice economy models. The NRDS targets and strategies are not realistic and included under estimation of rice consumption for Kenya, an …
In The Field The Women Saved The Crop: The Women’S Land Army Of World War Ii, Denna M. Clymer
In The Field The Women Saved The Crop: The Women’S Land Army Of World War Ii, Denna M. Clymer
Graduate Theses and Dissertations
The Women’s Land Army brought together rural and urban sectors of the United States in a climate of national and regional crisis. By the time the country was cast into war, the agricultural sector was already caught in a downward economic spiral that drove away laborers. With demand falling, and farms propped up only by experiments in subsidy and parity, when military and industrial jobs emerged in urban areas, farm laborers became scarce. At the same time the war created jobs for men outside of the agricultural sector, farm prices recovered and demand soared, forcing farmers to look to women …

Piglet Gut Microbiota Responses To Exposure To Outdoor Simulated Environment And Formula Feeding, Nguyen Vo
Piglet Gut Microbiota Responses To Exposure To Outdoor Simulated Environment And Formula Feeding, Nguyen Vo
Graduate Theses and Dissertations
Several lines of evidence suggest that early-life gut microbiota composition is a crucial determinant of the susceptibility to diseases later in life. Understanding the evolution of early-life gut microbiota and critical factors that can modify this microbial community will espouse the prevention or reversion of health risk originating from dysbiosis of the gut microbiota in the early stage. In this research, we hypothesized that alterations in the environment (simulation of rural conditions by soil exposure) and feeding mode (breastmilk versus formula milk) will have significant impacts on the establishment of the gut microbiota in early life. At first, in literature …

The Bracero Program In The Arkansas Delta: The Power Held By Planter Elite, William Chase Whittington
The Bracero Program In The Arkansas Delta: The Power Held By Planter Elite, William Chase Whittington
Graduate Theses and Dissertations
This paper examines the Bracero Program and its implementation from the start of World War II to the end of the program in 1964. Farmers and planters in America needed a sufficient labor supply once the war started, and Mexico became the main supplier. The Bracero Program was initiated as a war effort and meant to only last until the end of the war, but the planter elite had far different intentions once they realized how productive and inexpensive the program could be. This paper identifies the leading causes for how the Bracero Program was able to last over twenty …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …
