Governing The Rurals: Food Security And Governance In The 21st Century, Gina Paola Rico Mendez Dec 2016

Governing The Rurals: Food Security And Governance In The 21st Century, Gina Paola Rico Mendez

Theses and Dissertations

This dissertation develops a theory about the consolidation of state legitimacy given transformations in food security. Food security has moved from a national food maximization effort to the provision of food to households and individuals, regardless of the production source. This definitional change was triggered by urbanization, industrialization of agriculture and liberalization of trade. These dynamics altered the formula for balance and control of a country’s territory; as agricultural output moved into a global context, urban centers became less reliant on its periphery for sustenance and thus governments have fewer incentives to provide governance of any quality to rural areas. …

Natural Population Dynamics Of Rock Iguanas In The Bahama Archipelago, Giuliano Colosimo Dec 2016

Natural Population Dynamics Of Rock Iguanas In The Bahama Archipelago, Giuliano Colosimo

Theses and Dissertations

Understanding whether groups of individuals represent a single panmictic gene pool, or multiple genetically structured populations across a species range should aid in predicting whether specific conservation strategies would be more or less effective for species preservation. Further, contrasting the population structures of multiple coexisting taxa could foster an even deeper understanding of evolutionary divergence among demes and potentially even suggest local adaptation in the form of tight coevolutionary relationships. Finally, the analysis of population dynamics within small and isolated populations could improve our understanding of the relative importance that different evolutionary mechanisms have in predicting population persistence in the …

Nitrogen And Potassium Management In Container Production Of Musa, Ensete, And Canna And Landscape Performance Of Musa, Ensete, And Musella, Maddox Martin Miller Dec 2016

Nitrogen And Potassium Management In Container Production Of Musa, Ensete, And Canna And Landscape Performance Of Musa, Ensete, And Musella, Maddox Martin Miller

Theses and Dissertations

Two container production studies (nursery area and greenhouse) and a landscape performance study to evaluate bananas and cannas were performed at R. R. Foil Plant Science Research Center on the campus of Mississippi State University. Previous reports determined that there is greater need of K2O fertilization in addition to N for tropical monocot nutrition. Contradictory to previous cultural recommendations for landscapes, it was determined that a N:K2O ratio is not significant for container production of Musa, Ensete, and Canna in pine bark substrate. Nitrogen rate was the most significant variable in the containerized production of Musa, Ensete, and Canna. The …

Strategies For Establishment And Low Input Forage Production Of Southeastern Wildrye, Matthew Thomas Thornton Dec 2016

Strategies For Establishment And Low Input Forage Production Of Southeastern Wildrye, Matthew Thomas Thornton

Theses and Dissertations

Southeastern wildrye (Elymus glabriflorus (Vasey ex L.H. Dewey) Scrib & C.R. Ball) is a relatively new perennial cool-season grass that has shown potential as a forage crop in the Southeastern United States. However, there is a lack of research on this species assessing its agronomic performance. To assess the agronomic performance and it’s tolerance to imazapic field trials were established in Newton and Starkville, MS. A forage production trial included five nitrogen (N) 0, 56, 112, 168, and 224 kg N ha -1 (high input) and five annual clover (low input) treatments. Tolerance to imazapic was assessed with applications of …

Role Of Selenium In Age-Related Degeneration: Selenotranscriptome Hierarchy And Characterization Of Selenoprotein H, Lei Cao Dec 2016

Role Of Selenium In Age-Related Degeneration: Selenotranscriptome Hierarchy And Characterization Of Selenoprotein H, Lei Cao

Theses and Dissertations

Selenium (Se) is an essential trace element exerting its biological functions mainly through selenoproteins. Our lab has recently shown a paradoxical role of dietary Se at nutritional levels of intake in the delay of age-related degeneration while reducing longevity in mice carrying humanized telomeres. The first aim of this dissertation was to evaluate the effects of long-term dietary Se deficiency, aging, and sex on selenotranscriptome hierarchy in tissues. Four unique patterns in selenotranscriptomic changes were summarized. First, the responses of selenotranscriptomes to dietary Se deprivation and aging were sexually dimorphic. Second, a few selenoproteins responded to dietary Se deficiency and …

The Effects Of Sub-Lethal Chlorine Induced Oxidative Stress On Biofilm Formation And Thermal Resistance Of Salmonella, Janak Dhakal Dec 2016

The Effects Of Sub-Lethal Chlorine Induced Oxidative Stress On Biofilm Formation And Thermal Resistance Of Salmonella, Janak Dhakal

Theses and Dissertations

The effect of sub-lethal chlorine stress on various strains/serotypes of Salmonella on biofilm formation and thermal resistance was studied. The effect of oxidative stress (induced by 150 ppm of chlorine in TSB) on Salmonella biofilm formation on polystyrene and stainless steel surfaces at three temperatures (4°C, 30°C, and room temperature) in nutrient rich (full strength TSB) and nutrient limited conditions (1/10th TSB) was evaluated. On polystyrene surface, chlorine stressed S. Heidelberg (strain ID 72), S. Newport (strain ID 107) and S. Typhimurium (ATCC 14028) formed stronger (P < 0.05) biofilms at 30°C. On stainless steel, the chlorine stressed S. Heidelberg (ATCC 8326) and S. Enteritidis (ATCC 4931) at room temperature formed stronger (P < 0.05) biofilms as compared to the non-stressed control cells. The thermal resistance of short-term (1h) and long-term (27d) chlorine stressed Salmonella Heidelberg and S. Typhimurium were compared with the non-stressed controls at three different temperatures (55°C, 58°C and 61°C) and two growth phases (logarithmic and stationary). The short-term stressed log phase cells (both serotypes) were found to be more sensitive (P< 0.05) to thermal inactivation in TSB. Upon long-term sub-lethal chlorine exposure, Salmonella developed a rugose morphotype on tryptic soy agar at 37°C. The rugose morphotype provided significant thermal protection (P< 0.05) against heat stress as compared to smooth morphotype. In chicken broth, at 55°C, short-term chlorine stressed stationary phase S. Typhimurium displayed a higher D55 value compared to non-stressed cells. The findings from this research reveal that some Salmonella strains have the potential to form stronger biofilms and exhibit higher thermal tolerance upon exposure to sub-lethal chlorine concentration.

Mental Illness In Starkville, Ms: A Cultural Consensus Analysis Of The Public Conceptions Of Mental Illness, Curtis Andrew Kennett Dec 2016

Mental Illness In Starkville, Ms: A Cultural Consensus Analysis Of The Public Conceptions Of Mental Illness, Curtis Andrew Kennett

Theses and Dissertations

Mental illness is a complex phenomenon that is social and psychological as well as biological. But since the creation of the DSM-III in the 1980s, the landscape of mental health research and treatment in the United States has been heavily influenced by the biomedical model. The thoughts and beliefs of the lay public about mental illness are often ignored despite the push for greater cultural understanding among biomedical professionals. This disconnect, coupled with the poor mental health infrastructure, has left Mississippi with an inadequate ability to help Mississippians address mental illness. This research uses cognitive anthropological methods and biocultural theory …

Hopping Ahead Of Climate Change: Snowshoe Hares, Science, And Survival, Tessa Mcmillan

Children's Book and Media Review

Deep in the woods of Montana, biologist Scott Mills notices a big problem with a small animal. The snowshoe hares he has studied for most of his career are not changing their coat colors fast enough to protect themselves from predators. With season lengths fluctuating due to climate change, many snowshoe hares are getting killed off quicker because they haven’t molted fast enough to match their environment. Without any outside aid, snowshoe hares could become a threatened species. To learn more, Mills is studying coat-changing animals in a variety of climates. In Washington state, not all snowshoe hares molt to …

The Role Of Ephb3 In Cortical Vascular Integrity Following Traumatic Brain Injury, Poincyane Assis-Nascimento Dec 2016

The Role Of Ephb3 In Cortical Vascular Integrity Following Traumatic Brain Injury, Poincyane Assis-Nascimento

Open Access Dissertations

Traumatic brain injury (TBI) continues to be a major health concern worldwide. One of the earliest and most profound deficits comes from vascular damage and breakdown of the blood-brain barrier (BBB). Despite the consequences of blood vessel destruction, little is known of the cellular responses that occur in vessel integrity following TBI. B class ephrins and Eph receptors are membrane bound proteins that initiate bidirectional signals during cell-cell interactions, and are indispensable for developmental and pathological neovascularization. The role of EphB3 and its ligand ephrinB3 was investigated in vascular integrity in a murine controlled cortical impact (CCI) injury model of …

Condos, Connectivity, And Catch: Analyzing The State Of The Bahamian Spiny Lobster Fishery., Karlisa Alicia Callwood Dec 2016

Condos, Connectivity, And Catch: Analyzing The State Of The Bahamian Spiny Lobster Fishery., Karlisa Alicia Callwood

Open Access Dissertations

Caribbean spiny lobster (Panulirus argus) is a heavily exploited seafood throughout its range and supports the primary fishery in The Bahamas. However, its long pelagic larval duration and, thus, potential for long-range dispersal increases the difficulty in determining the origins of local populations and complicates management. In recent years, the Bahamian fishery has transitioned to the use of condos (or casitas) as the primary fishing method. Condos are relatively inexpensive to construct and deploy, and it is estimated there are now over a million deposited throughout the Bahama banks. Collectively, these factors, coupled with an increased level of effort in …
