Charitable Donations: An Analysis Of The Differences In Donation Patterns By Income Level, Elizabeth Ficklin Dec 2014

Charitable Donations: An Analysis Of The Differences In Donation Patterns By Income Level, Elizabeth Ficklin

All Theses

This thesis examines the possibility of grouping charitable donors by income level to develop a set of models that can more accurately predict charitable donations. Previous work is inconsistent in predicting charitable donations. This work helps to determine if these inconsistencies are a result of methodological differences between researchers, or if group membership is an important factor in predicting charitable donations as suggested by some researchers. This research only found four variables that were common to all three income groups, frequency of church attendance, family income, age, and years of education. Results show that additional variables can serve as predictors …

Empowering Citizens In A Global Era: A Grounded Theory Study Of Community Gardens, Anita Tam Dec 2014

Empowering Citizens In A Global Era: A Grounded Theory Study Of Community Gardens, Anita Tam

All Dissertations

In our global era, the modern food system can be viewed as consisting of a dominant macro-level corporate food industry, challenged by broad-based meso-level food justice and democracy movements, which are in turn fueled by micro-level community food initiatives. Research has yet to examine the role of community gardens in the context of this complex, multi-level food system. Grounded theory methodology was thus used to explore the deeper meaning of the community gardening experience to participants, in order to better understand the ways in which community gardens may scale up and contribute to democratizing the food system. Analysis of the …

Design With Emotion: Improving Web Search Experience For Older Adults, Tamirat Abegaz Dec 2014

Design With Emotion: Improving Web Search Experience For Older Adults, Tamirat Abegaz

All Dissertations

Research indicates that older adults search for information all together about 15% less than younger adults prior to making decisions. Prior research findings associated such behavior mainly with age-related cognitive difficulties. However, recent studies indicate that emotion is linked to influence search decision quality. This research approaches questions about why older adults search less and how this search behavior could be improved. The research is motivated by the broader issues of older users' search behavior, while focusing on the emotional usability of search engine user interfaces. Therefore, this research attempts to accomplish the following three objectives: a) to explore the …

Determining Dna Damage Prevention Mechanisms For Multifunctional Selenium And Sulfur Antioxidants And The Dna-Damaging Capabilities Of Clotrimadozle And Pseudoephedrine-Derived Metal Complexes, Matthew Todd Zimmerman Dec 2014

Determining Dna Damage Prevention Mechanisms For Multifunctional Selenium And Sulfur Antioxidants And The Dna-Damaging Capabilities Of Clotrimadozle And Pseudoephedrine-Derived Metal Complexes, Matthew Todd Zimmerman

All Dissertations

DNA damage by reactive oxygen species (ROS) is a cause of many chronic diseases. This work examines the ability of sulfur and selenium antioxidants to prevent oxidative DNA damage and the mechanisms for this activity. Although iron- and copper-generated hydroxyl radical are primary causes of damage under oxidative stress conditions, studies typically focus on ROS scavenging rather than antioxidant-metal binding as a mechanism for sulfur and selenium antioxidant behavior. Mass spectrometry studies of sulfur and selenoamino acids (Chapter 2) show that most form CuI and FeII complexes, regardless of their metal-mediated DNA damage prevention abilities. Because their electrochemical properties do …

The Depressing Of China's Economy: The Effect Of Rural---Urban Educational Inequality And Absence Of Land Market, Huayong Zhou Dec 2014

The Depressing Of China's Economy: The Effect Of Rural---Urban Educational Inequality And Absence Of Land Market, Huayong Zhou

All Dissertations

This paper argues that too many workers were placed in traditional agricultural sector in China's economy after 1978. I investigate two factors which hindered the labor mobility from agricultural and non-agricultural sector: (1) human capital dierence between rural and urban workers brought by China's urban oriented public educational policy; (2) absence of land property rights and a well functioning land market. I incorporate those two frictions into a two-sector dynamic macro model. I calibrate the model and show that it provides a good fit for the evolution of GDP per-capita and employment share in agriculture in the Chinese economy. I …

Allosteric Regulation Of Bacterial And Fungal Xylulose 5-Phosphate/ Fructose 6-Phosphate Phosphoketolases (Xfps), Katie Glenn Dec 2014

Allosteric Regulation Of Bacterial And Fungal Xylulose 5-Phosphate/ Fructose 6-Phosphate Phosphoketolases (Xfps), Katie Glenn

All Dissertations

Acetate is excreted as a metabolic end product in many microbes. Acetate production has primarily been studied in bacteria and archaea but is known to occur in eukaryotic organisms as well. For example, acetate is one of the most abundant metabolites excreted by the fungal pathogen Cryptococcus neoformans during cryptococcosis suggesting that acetate production may be important during pathogenesis. One possible pathway for acetate production in C. neoformans involves the enzymes xylulose 5-phosphate/ fructose 6-phosphate phosphoketolase (Xfp), which can generate acetyl phosphate from either fructose 6-phosphate (F6P) or xylulose 5-phosphate (X5P), and acetate kinase (Ack), which can then convert acetyl …

Biology And Control Of The Bed Bug Cimex Lectularius L., Kevin Hinson Dec 2014

Biology And Control Of The Bed Bug Cimex Lectularius L., Kevin Hinson

All Dissertations

After vanishing from the public eye for more than 50 years, bed bugs have resurged to become one of the most widely discussed and heavily researched insect pests in the westernized world. Our inability to prevent and successfully treat infestations has been the driving force behind this wave of research. I addressed gaps in our understanding of bed bugs by examining behavioral and life history characteristics, as well as insecticide application responses. I showed that natural-based products are generally ineffective against bed bugs, particularly when used as a residual treatment. I also found that bed bugs may be killed through …

Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan Nov 2014

Post-Hurricane Fuel Dynamics And Forest Regeneration Of Coastal Pine Stands In Southeast United States, Shanyue Guan

All Theses

Hurricanes have long been powerful and recurring disturbances in many coastal forest ecosystems. Intense hurricanes often produce a large amount of dead fuels within their affected forests, but how post-hurricane fuel complex changes with time, due to decomposition and management such as salvage, and the fire behavior affected by the changed fuel load remains largely unknown. To better understand the fuel and regeneration dynamics, field measurement and modeling were conducted within undamaged stands and hurricane damaged stands, including salvaged and unsalvaged stands in southern pine forests impacted by hurricane Hugo (1989), Opal (1995), Katrina (2005), and Ike (2008). We found …
