Masters Theses

Oxalobacter formigenes is a beneficial, strict anaerobic gut bacterium that plays an important role in the prevention of kidney stone disease with a unique characteristic of using only oxalate as a carbon and energy source. To date, twenty-one strains of O. formigenes have been isolated which are further divided into two groups based on differences in the patterns of cell membrane lipids, cellular proteins, and nucleic acid fragments. The objective of the study was to evaluate intra-species diversity of O. formigenes strains using pulsed-field gel electrophoresis (PFGE) and multiplex PCR.

Nine pure cultures of O. formigenes strains (5 strains group …

An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine

Masters Theses

Large rivers are highly important systems; being exploited both commercially and recreationally. Because of this usage by humans, close monitoring of the ecology of theses rivers is of the utmost importance. The Long-Term Electrofishing project (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using day time, pulsed-DC electrofishing during the late Spring through the early Fall each year. Given that previous studies have noted diel and seasonal changes in catch and composition of fish communities, the addition of night time electrofishing may be beneficial to the overarching goals of the LTEF. This study sought to …

Relationship Of Self-Construal To Perceived Availability And Seeking Of Social Support By International Students Studying Abroad In The United States, Yue Zhang

Masters Theses

This study was created to examine the relationship between different self-construals and the behavior of seeking social support or the perceived availability of social support. We recruited 84 international students who currently study abroad in the United States. Participants completed the Singelis Self-construal Scale (SCS; Singelis,1994) and a Social Support Scale created for the current study. The SCS measured the degree to which participants’ self-construals are Independent (IND) or Interdependent (INT). The Social Support Scale presented five different scenarios and asked participants to rate activities responding to two types of social support (tangible support and emotional support). I predicted that …

Risk-Taking Behaviors As Predicted By (Mal)Adaptive Functioning In College Students: A Look Into Emotional Adjustment, Hillary Smith

Theses and Dissertations

Risk-taking behaviors emerge, increase, and peak during adolescence and have shown to continue into late adolescence. Research has begun to explore how some forms of risk-taking may be normative and adaptive. The aim of this study is to look at how social, academic, and occupational functioning are related to risk-behaviors, as measured by risk-favorability and reported risk-taking history, and emotional adjustment in a college sample (N=314). Risk was assessed using self-report and an implicit task, both of which were moderately correlated. Both risk measures were negatively correlated with self-report measures of adaptive functioning and emotional adjustment.A series of mediation analyses …

Farm To Label: A Critique Of Consumer Activism In The Sustainable Food Movement, Olivia Whitener

Pomona Senior Theses

“Local,” “organic,” “natural,” and “Fairtrade” are just several of the many claims adorning the food products that line grocery store shelves. These promises of environmental sustainability and social responsibility are pillars of the “good food revolution” sweeping the nation as consumers demand alternatives to the products of the industrial food system. Green consumerism, the premise that consumer demand for environmentally sustainable goods will bring about ecologically beneficial outcomes, is at the heart of the sustainable food movement. This thesis takes a critical look at the operation of green consumerism in the food system. It explores the ideology and shortcomings of …

In The Eye Of The Storm: Houston After Hurricane Harvey, Brandon Tolentino-Serrano

Pomona Senior Theses

Situated in one of the wettest climates in America, Houston, TX has had a long history of heavy rains and unprecedented floods. Unfortunately, floods have become more common over the last few decades as climate change increases the frequency and intensity of hurricanes around the globe. To complicate matters further, Houston has quickly sprawled to accommodate over 2.5 billion people. Rapid urbanization has rendered the landscape even more susceptible to floods through excess concretization and watershed disturbance. This thesis traces the history of the Bayou City in relation to the damages caused by Hurricane Harvey. By mapping out the original …

Changing Oceanic Conditions On The Foraging Patterns Of Cassin’S Auklets, Ptychoramphus Aleuticuschanging Oceanic Conditions On The Foraging Patterns Of Cassin’S Auklets, Ptychoramphus Aleuticus, Clare Flynn

Pomona Senior Theses

Cassin’s auklet (Ptychoramphus aleuticus) reproductive success has been monitored on Southeast Farallon Island (SEFI) for the past 45 years. Their productivity has varied with oceanic conditions. The purpose of this study is to connect how oceanic conditions affect Cassin’s auklet foraging behaviors. The California Current System (CCS) can normally maintain high plankton productivity, and thus high seabird productivity, because of coastal upwelling. I hypothesized that lower upwelling and/or higher sea surface temperatures (SSTs) lead Cassin’s auklets to spend more time on intensive foraging behaviors such as flying and diving, and have less time to spend resting. I also hypothesized that …

A Class Of Finite Difference Schemes For Singularly Perturbed Delay Differential Equations Of Second Order, Pramod Chakravarthy Podila, Kamalesh Kumar

Turkish Journal of Mathematics

In this paper, we proposed a new class of finite difference schemes for solving singularly perturbed delay differential equation of second order. The proposed schemes are oscillation-free and more accurate than conventional schemes on a uniform mesh. These schemes are easily adaptable on special meshes like Shishkin mesh or Bakhvalov mesh and are uniformly convergent with respect to the perturbation parameter. The error analysis has been carried out and numerical examples are presented to show the accuracy and efficiency of the proposed schemes.

On Isotropic Projective Ricci Curvature Of C-Reducible Finsler Metrics, Laya Ghaemnezhad, Bahman Rezaei, Mehran Gabrani

Turkish Journal of Mathematics

Projective Ricci curvature is a projective invariant quantity in Finsler geometry which is introduced by Z. Shen. In this paper, we study special projective Ricci curvature of C-reducible Finsler metrics. The necessary and sufficient conditions of these metrics, which cause these metrics to be weak or isotropic projective Ricci curvature, are found and it is proved that C-reducible Douglas metric of isotropic PRic-curvature must be PRic flat. The same theorem for C-reducible metrics of scalar flag curvature is also investigated.

Global Dynamics Of Perturbation Of Certain Rational Differenceequation, Sabina Hrustic, Mustafa Kulenovic, Samra Moranjkic, Zehra Nurkanovic

Turkish Journal of Mathematics

We investigate the global asymptotic stability of the difference equation of the form \begin{equation*} x_{n+1}=\frac{A x_{n}^{2}+F}{a x_{n}^{2}+e x_{n-1}}, \quad n=0,1,\ldots, \end{equation*}% with positive parameters and nonnegative initial conditions such that $x_0 + x_{-1}>0$. The map associated to this equation is always decreasing in the second variable and can be either increasing or decreasing in the first variable depending on the parametric space. In some cases, we prove that local asymptotic stability of the unique equilibrium point implies global asymptotic stability.

Sherman's Inequality And Its Converse For Strongly Convex Functions Withapplications To Generalizedf-Divergences, Slavica Ivelic Bradanovic

Turkish Journal of Mathematics

Considering the weighted concept of majorization, Sherman obtained generalization of majorization inequality for convex functions known as Sherman's inequality. We extend Sherman's result to the class of n-strongly convex functions using extended idea of convexity to the class of strongly convex functions. We also obtain upper bound for Sherman's inequality, called the converse Sherman inequality, and as easy consequences we get Jensen's as well as majorization inequality and their conversions for strongly convex functions. Obtained results are stronger versions for analogous results for convex functions. As applications, we introduced a generalized concept of f-divergence and derived some reverse relations for …
