The Role Of At Epistemic Community In Haitian Education Reform Post Earthquake 2010, Joy Okeefe

Master's Theses

This is a study of the role of an epistemic community involved in the policymaking of education reform in Haiti after the devastating earthquake of 2010. It uses Peter M. Haas' (1992) framework as a theoretical lens. According to Haas, epistemic communities are conceptualized as "a network of professionals with recognized expertise and competence in a particular domain and an authoritative claim to policy relevant knowledge within a domain or issue area" (3). The epistemic communities involved in the policymaking of the current education reforms specifically related to privatization in Haiti are identified and analyzed through the content analysis of …

Women's Access To Secondary Education In Colonial And Postcolonial Tanzania And Rwanda, Emlyn Ashley Ricketts

Master's Theses

This paper will examine how the politics of colonialism and independence during the twentieth century, as well as the culture of each country, have created and limited secondary educational opportunities for women in Tanzania and in Rwanda. I will argue that the English and Belgian colonizers' goals of the education systems in colonial Tanganyika and Ruanda-Urundi-how much education they thought was appropriate for women to have and their overarching goals in creating the education systems in the colonies-shaped the place of women within Tanzania and Rwanda today. I will argue that English and Belgian colonizers imposed a western, Christian, patriarchal …

Characterization Of Hydride-Based Silica And Diamond Hydride Stationary Phases, Nima C. Parmar

Master's Theses

Aqueous normal phase chromatography possesses characteristics of both normal phase (NP) and also reverse phase (RP) chromatography. It can retain polar as well as non-polar compounds by carefully selecting the concentration ratio of organic solvent to water in the mobile phase. Silica hydride columns contain only a small percentage of silanol groups which are polar in nature and have an effect on the separation process. Diamond hydride columns consist of a small amount (~2%) of carbon chemically bonded to a silica hydride surface.

This research work characterized both hydride-based silica and diamond hydride stationary phases under isocratic and gradient conditions. …

Immobilization Of Rhodococcus Erythropolis As A Potential Treatment For Atherosclerosis, Srikanth Darbha

Master's Theses

Cardiovascular disease is the leading cause of death in the United States and isprimarily due to hypercholesterolemia. The novel approach of combatting atherosclerosis presented in this research entails delivery of microencapsulated Rhodococcus erythropolis immobilized in biodegradable alginate-based microcapsules and utilizing the bacterium's cholesterol oxidase enzyme pathway to degrade cholesterol from intermediate-stage arterial plaque. The bacterial growth medium was optimized using Taguchi design methods to enable growth characterizations hindered by biosurfactant by-product. Methodologies for extraction and quantification of biosurfactant and cholesterol were developed and conducted simultaneous to bacterial growth assessment. Bacteria were encapsulated using atomization (850±50 μm) and inkjet bioprinting (32±5 …

Farms On Campus: Strong Stakeholder Support For An Educational Garden At A Non-Land-Grant University, Gina M. Bacigalupi

University farms and gardens are increasingly seen as effective tools for learning a variety of academic subjects and as resources that allow users to connect experientially to nature. Most existing university farms, however, are found at resource-rich land-grant universities. This research evaluated stakeholder interest and willingness-to-pay in money, time, and labor for a proposed educational farm at a public, urban, non-land-grant university through an online survey of over 400 members of the California State University East Bay, Concord Campus community. Overall, support for an educational farm at this site was high amongst all stakeholder groups. Students and stakeholders who hold …

Intra-Annual Changes In Population Parameters As Indicators Of Humpback Whale (Megaptera Novaeangliae) Migratory Behavior, Casey Clark

Master's Theses

Many techniques used to study animal migrations rely on observations of specific animals, which provide valuable information about individuals studied but do not capture population variability. By examining changes in population parameters, researchers may gain a better understanding of migratory behaviors. In this study, intra-annual changes in population parameters were used to study migratory behaviors of humpback whales off central California in 2011/2012. Data were compared with a historic dataset from 2004/2005. Parameters measured included sex ratio, pregnancy rate, mitochondrial DNA haplotype frequencies and mean δ13C and δ15N values. Weighted moving averages of the sex ratio were moderately effective at …

Benthic Invertebrate Response To Habitat Complexity In South Bay Salt Ponds, Jessica Louise Murphey

Master's Theses

Wetlands are unique ecosystems that support specific flora, fauna, hydrology, and geology. These ecosystems increase groundwater availability, improve water quality, decrease flood water impacts, and help decrease shoreline erosion. In the south San Francisco Bay, the South Bay Salt Pond Restoration Project is restoring over 6,000 hectares of former salt ponds to tidal marshes and managed pond habitats. These habitats will support endangered species as well as migratory birds, diving ducks, invertebrates, and algal species. Benthic invertebrates are a vital piece of the South Bay food web as they provide the sustenance for other invertebrates, fish, shorebirds, and waterfowl. Improving …

A Pilot Program To Evaluate The Effect Of Training Table-Based Nutrition Education And Menu Modification On The Nutrition Knowledge And Dietary Intake Of Collegiate Football Players At A Ncaa Division I University, Rida Wali

Master's Theses

Since collegiate football is a revenue generating sport for many institutions, it is likely that these athletes are under pressure to maximize performance and thus may resort to unsafe or unproven nutritional practices. Athletes lacking nutrition knowledge may not be able to adequately nourish themselves, which may negatively impact their performance and overall health. In the literature, it is indicated that the athletic staff is a source of nutrition knowledge for athletes. However, the training table - which is a meal provided by the athletic staff, has previously not been explored as an avenue for nutrition education and intervention. This …

Foraging Behavior, Habitat, Health, And Survival Of Resident And Translocated Hawaiian Monk Seals At Nihoa Island, Hawaii, Tenaya A. Norris

Master's Theses

Translocations aimed at promoting population recovery for threatened and endangered species also can function as forced dispersals. To assess the efficacy of translocating Hawaiian monk seals (Monachus schauinslandi) and examine post-dispersal effects on monk seals, in 2008-2009, 12 weanling seals were translocated from French Frigate Shoals (FFS) to Nihoa Island (NIH). In addition, nine adult and eight weanling resident seals were captured at NIH. Satellite instrument attachment, biological sampling, and morphometry were conducted on seals at capture. Focal video camera drops also were conducted at 45 sites around NIH (< 100 m) in 2010-2011. Translocated and resident weanlings primarily dove to 40-60 m and used sandy-bottomed habitat < 13 km from NIH. In contrast, resident adults had greater variability in foraging behavior and habitat use. There also was a low prevalence of infectious disease in translocated and resident seals, excluding Chlamydophila abortus and enteric bacteria. First-year survival was greater for …

Use Of Stair Prompts To Encourage Physical Activity, Nima Chhay

Master's Theses

Stair prompts can encourage stair use in both public and private settings and thereby increase overall physical activity. Stair visibility in multilevel buildings increases stair use. For this study, an intervention using a modified New York City Department of Health and Mental Hygiene stair prompt was implemented to encourage stair use in an academic setting. The modification included a time management theme, chosen because individuals in this setting may find taking the stairs to be faster than taking the elevator. To evaluate the effectiveness of the modified stair prompt, two buildings--one with hidden stairs and one with visible stairs--were selected …

Safe Sex As Patriotic Ideograph In Wartime Std Prevention Campaigns, Jessica Ann Johnson

Master's Theses

Sexually transmitted diseases (STDs) are a problem that has afflicted people in the USA for centuries. Health communication and mass communication scholars have attempted to determine the effectiveness of STD prevention campaigns. It is crucial for scholars to take into account the persuasiveness of these campaigns and beliefs that become significant to these campaigns.

This rhetorical history examines how acted as a patriotic ideograph in World War I and II STD prevention campaigns. A history of war and knowledge associated with STDs gives readers a broad overview of the cultural aspects that are a part of the context of this …

Evaluating Hypotheses That Explain Non-Continuous Responses To Syllable Periods ("Skipping") During Phonotaxis By Female Acheta Domesticus, Tori Joy Steely

Master's Theses

One way to classify female cricket phonotactic response is as "non-skipping" or "skipping." "Skipping" is defined as crickets that respond to a non-continuous range of calling songs. This investigation evaluates the temporal aspects of typical phonotactic protocols and attempts to determine if "skipping" is due to a filtering mechanism or if "skipping" is an artifact of testing protocol. Rather than a notch filter or testing parameters inhibiting a phonotactic response to a syllable period within the range of a band pass filter, I hypothesize that "skipping" occurs as a result of the probabilistic nature of phonotaxis.

The Effect Of Bmi On The Age Of Menarche In Adolescent Girls, Samara R. Sterling

Master's Theses

Problem. Over the past century, the age of menarche has consistently declined in the United States and globally. Obesity has also increased by 82% globally over the past 20 years. Obesity, as measured by BMI percentiles in children, may contribute to the declining age of menarche. -- Method. Adolescent girls ages 12-19 were examined in California and Michigan. Physical development and the age of menarche were assessed through an online questionnaire. Height and weight measurements were taken at a clinic and converted to BMI percentile values. -- Results. A negative correlation was observed between BMI percentile values and the age …

Snail Induces Mesenchymal Transition And Promotes Egfr Tki Resistance In Nsclc Cells Harboring Efgr Kinase Domain Mutations, Rutu Gandhi

Master's Theses

Lung cancer is the leading cause of cancer related death, accounting for one third of all deaths from cancer worldwide. About 85-90% of lung cancers are non-small cell lung cancers (NSCLCs). Molecular targeted therapies such as epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) provide an effective treatment option for oncogene addicted NSCLC. However, the development of resistance to EGFR TKIs continues to be the major limitation in the treatment of NSCLC. Resistance to EGFR TKIs has been associated with the loss of canonical epithelial protein E-cadherin, suggesting involvement of epithelial to mesenchymal transition (EMT) in conferring EGFR TKI …

Identifying And Characterizing The Degradative Pathway Of The Retroviral Restriction Factor Rhtrim5Α, Rachel Nelson

Master's Theses

Human immunodeficiency virus 1 (HIV-1) is a lentivirus that progresses to acquired immunodeficiency syndrome (AIDS). The protein TRIM5alpha from rhesus macaques (rhTRIM5alpha) restricts HIV-1 by blocking infection after entry of the virion into cells. Treatment of rhTRIM5alpha expressing cells with inhibitors to a cellular degradation pathway, the proteasome, partially relieves restriction but does not inhibit rhTRIM5alpha protein turnover. The role of a second degradation pathway, the autophagy-lysosomal pathway, in TRIM5alpha mediated restriction has not been explored.

In the present study, we demonstrate that rhTRIM5alpha is degraded by chaperone mediated autophagy (CMA). Inhibition of CMA alters rhTRIM5alpha localization and turnover, while …

Selective Expansion Of B Cells By Intestinal Microbiota, Karina Ochoa

Master's Theses

In rabbits, antibody diversity and B cell expansion are generated in gut-associated lymphoid tissues (GALT), in an antigen- and T cell-independent mechanism, and require interaction with intestinal microbiota. I investigated, in vitro, the mechanism by which commensals drive GALT reactions. Bacteria were isolated from the GALT of rabbits and identified by 16sRNA sequencing. I found that the commensals can bind to Ig, independently of their specificity. In addition, a ~20kDa bacterial molecule was immunoprecipitated with recombinant Ig molecules. Stimulation of B cells with selected bacterial molecules induced the activation of B cells. Stimulation of B cells through TLR2 induced the …

A Practical Scale For Multi-Faceted Organizational Health Climate Assessment, Zandra M. Zweber

Master's Theses

The current study sought to develop a practical scale to measure workplace health climate in a way that has not previously been conceptualized – as a three-faceted approach from the employee perspective serving as an indicator of a healthy organization. The goal was to create a short, useable yet comprehensive scale that could translate into practical use by organizations and occupational health professionals planning workplace interventions. To accomplish this, the proposed multi-faceted organizational health climate scale (MOHCA) assesses three-facets which match up with three organizational levels: 1) organization 2) supervisor and 3) workgroup. Ten items were developed and tested on …

Identifying And Characterizing Non-Coding Rnas In The Dinoflagellate Karenia Brevis, Helen Namataka

Master's Theses

When algal cells proliferate and accumulate in marine and fresh water systems, they form algal blo'oms. The majority of these blooms are beneficial, but a significant number are detrimental and are known as harmful algal blooms (HABs). A number of negative effects, including closing of recreational beaches and economic loss, are observed during HABs. Predictably, the longer a bloom persists, the greater its effects on human, environmental and economic health. Karenia brevis, a mixotrophic dinoflagellate, forms HABs, and blooms caused by this organism have been known to remain several months after formation. For these reasons, research has been conducted to …

Fungal Biofilm Colonization And Succession On Artificial Reefs In The North-Central Gulf Of Mexico, Amy Leigh Salamone

Master's Theses

This study represents the first characterization of natural mixed-species fungal biofilm communities on artificial reefs in the marine environment. Previous fungal biofilm studies have failed to observe the naturally-occurring biodiversity in coastal areas, which comprise the most utilized zone of the marine environment. Artificial reefs can increase fishing yields, amplify oyster habitats, contribute to shoreline stabilization, promote good water quality, and deter pollution. Proper management practices of artificial reefs require knowledge of the colonization of these new habitats by marine organisms and their subsequent succession. Fungi, along with bacteria, archaea, protists, algae, and diatoms, quickly form a complex biofilm on …

Carbon And Nitrogen Dynamics In High Intensity Minimal Exchange Shrimp (Litopenaeus Vannamei) Raceways, John Henry Francis

Master's Theses

Three separate shrimp (litopenaeus vannamei) growouts were examined at The University of Southern Mississippi's Thad Cochran Marine Aquaculture Center. The objectives of this project were to (1) determine if there was a significant difference in any water quality parameters between the 2 density treatments, (2) construct carbon and nitrogen budgets to see where the carbon and nitrogen went in the system for all growouts, (3) determine if plastic media had any effects on water quality parameters and shrimp production, (4) determine if plastic media allowed for a nitrifying bacteria population to establish more rapidly, (5) determine if the …

The Effects Of Growth Hormone On Primary Bovine Mammary Cell Models, Lisa Mcdonnell

Master's Theses

The ability of exogenous growth hormone (GH) to increase milk yield through insulin-like growth factor-1 (IGF-I) in dairy cows is well characterized. However, recent studies utilizing mammary epithelial cell lines indicate a direct effect of GH on mammary epithelial cells (MEC). To test if these observations are relevant in vivo and if this response differs between dairy breeds, three mammary models were utilized. Mammary explants from a lactating Jersey cow were cultured in classical lactogenic media (dexamethasone, insulin, and prolactin) with 0 or 10 ng/mL of recombinant bovine GH for 12h. Primary MEC from lactating Holstein and Jersey cows were …

Effect Of Short-Term Estrogen Depletion On Compact Bone Microdensitometry In The Ewe, Cailyn Bugbee

Master's Theses

Osteoporosis affects the human skeleton through the direct effects of the disease on the function and structure of bone. Individuals who are affected by osteoporosis may be subject to serious fractures and it is estimated that annually approximately 1.5 million fractures can be attributed to this disease [1]. The disease is categorized as the direct side effect of increased bone porosity and bone loss and is directly linked to estrogen deprivation [2]. Animal models are often used to make initial conclusions about the effects of the disease or pharmacological treatments. In this study, sheep were chosen as a representative animal …

An Economic Analysis Of Wine Grape Production In The State Of Connecticut, Jeremy L. Jelliffe

Master's Theses

The Connecticut Wine and Vineyard industry has grown at a steady 3.9% per year over the past decade (ATTTB, 2009). Economic models estimate that the wineries sub-sector contributes $38 million dollars to the state economy and direct employment of 106 residents (Lopez et al., 2010). Programs to support and foster further growth of the industry and CT farm vineyard culture include the Department of Agriculture’s CT Wine Trail and the annual CT Wine festival (DOAG, 2010). Farmland preservation groups also support vineyard development since grape growing tends to secure tracts of farmland for long periods of time.

However, the impact of household food security and federal food assistance participation on beverage habits has not been extensively analyzed. This paper sought to fill the current gap in literature on household beverage availability and recorded preschool child consumption of sugar sweetened beverages (SSB) and 100% fruit juice based on food security levels and status of federal food assistance participation. For this thesis, SSB are beverages that have added sugar and include fruit drinks, sodas, sports drinks, syrups, flavored milks, and teas. Baseline data from …

The Relationship Between Liv-1 And E-Cadherin (Cdh1) In Prostate Cancer Cells, Lei Cao

Master's Theses

BACKGROUND

The zinc importer LIV-1 is widely distributed, mainly in hormonally controlled tissues. Attention has focused on its role in breast cancer, especially its regulation by estrogen and epidermal growth factor (EGF) and its link to the Epithelial–Mesenchymal Transition (EMT) marker, E-cadherin (CDH1). EMT is important for tumor progression and metastasis. CDH1 expression is under complex control, including by two transcriptional repressors, Snail and Slug. Contrast to CDH1, elevated MMP-9 expression has been linked to increased metastasis and tumor stage.

METHODS

The role of LIV-1 in prostate cancer cell lines, LNCaP and DU145 was investigated. Cells were treated with or …

Master's Theses

ABSTRACT

COMPLETION OF AN IN VIVO DIGESTIBILITY TRIAL IN HORSES AND IN VITRO DIGESTIBILITY ASSAY DEVELOPMENT

Cassandra Renee Sweeney

In vivo analysis of equine feed digestibility has been the gold standard since the late 1800's, although it can be time consuming, costly, and labor intensive. In vitro digestibility analysis may be more economical and beneficial to both feed manufacturers and consumers. The availability of accurate in vivo data is crucial for critical evaluation and validation of any potential in vitro method (Coles et al., 2005). Ten adult American quarter horse geldings were used in the in vivo digestibility evaluation of …

Determining The Trophic Role Of Gulf Menhaden (Brevoortia Patronus) Using Carbon And Nitrogen Stable Isotopes, Zachary Olsen

Master's Theses

Gulf menhaden (Brevoortia patronus) play multiple roles in the Gulf of Mexico coastal ecosystem as filter feeders and as an important food source for many recreationally and economically important finfish. Gulf menhaden also support a large commercial fishery, and little is known about the impact of fishing on the role of this species as a filter feeder in the food web. This study examines the spatial, temporal and ontogenetic dynamics of food selectivity and trophic role observed in Gulf menhaden. The most important dietary item for juvenile fish was found to be phytoplankton (75.7% dietary composition) while that of subadults …
