Taxonomy And Systematics Of Plagioporus (Trematoda), With Descriptions Of 10 New Species From Freshwater Fishes Of The Nearctic, Thomas John Fayton Aug 2017

Taxonomy And Systematics Of Plagioporus (Trematoda), With Descriptions Of 10 New Species From Freshwater Fishes Of The Nearctic, Thomas John Fayton

Dissertations

The Opecoelidae Ozaki, 1925 is one of the largest families of digenetic trematodes of fishes. While the family is mostly marine/estuarine, invasion of freshwater hosts has occurred at least two times. The only representative freshwater plagioporine sequenced to date is Plagiocirrus loboides Curran, Overstreet, & Tkach, 2007, which previous phylogenetic analyses resolved as being related to deep water marine opecoelids. The taxonomy of the freshwater plagioporines, particularly Plagioporus, has long been confused; homoplasy is rife within the family and has complicated the delineation of species and genera, and the freshwater species from marine forms. Here, I hypothesize that the …

Inhibitory Control And Its Relation To Personality/Temperament, Executive Function, And The Brain, Sarah Mailander Dyer Aug 2017

Inhibitory Control And Its Relation To Personality/Temperament, Executive Function, And The Brain, Sarah Mailander Dyer

Dissertations

Inhibitory control, described as the ability to suppress one response in favor of a goal-directed response, is thought to play an important role in the development of emotional regulation as well as various forms of psychopathology, including ADHD. Up until very recently, inhibitory control has been researched within two completely separate fields of study: temperament and neuropsychology. In the temperament/personality literature, inhibitory control is a major component of the overarching temperament/personality factor of Effortful Control/Conscientiousness. In the field of neuropsychology, inhibitory control is considered one aspect of executive function. Further complicating the current understanding of inhibitory control is the complexity …

Generalized Partial Least Squares Approach For Nominal Multinomial Logit Regression Models With A Functional Covariate, Amani Mohammed H Albaqshi Aug 2017

Generalized Partial Least Squares Approach For Nominal Multinomial Logit Regression Models With A Functional Covariate, Amani Mohammed H Albaqshi

Dissertations

Functional Data Analysis (FDA) has attracted substantial attention for the last two decades. Within FDA, classifying curves into two or more categories is consistently of interest to scientists, but multi-class prediction within FDA is challenged in that most classification tools have been limited to binary response applications. The functional logistic regression (FLR) model was developed to forecast a binary response variable in the functional case. In this study, a functional nominal multinomial logit regression (F-NM-LR) model was developed that shifts the FLR model into a multiple logit model. However, the model generates inaccurate parameter function estimates due to multicollinearity in …

Evolution Of Caffeine Biosynthetic Enzymes And Pathways In Flowering Plants, Ruiqi Huang Aug 2017

Evolution Of Caffeine Biosynthetic Enzymes And Pathways In Flowering Plants, Ruiqi Huang

Dissertations

Convergent evolution generally refers to the independent evolution of similar biological function more than once in unrelated species. Caffeine is thought to have evolved by convergence, and is naturally produced through secondary metabolism in plants to defend against pathogen attack and insect feeding or to attract pollinators. The same caffeine biosynthetic pathway has been elucidated in Camellia (tea) and Coffea (coffee), in which xanthosine is sequentially methylated to caffeine via 7-methylxanthine and theobromine. However, although the same catalysis pathway is used, different (paralogous) enzymes in the SAMT/BAMT/theobromine synthase (SABATH) multigene family are used in the two species. In my dissertation, …

The Moderating Role Of Sex On Gender Role Orientation’S Meditation Of Work-Family/Family-Work Conflict And Satisfaction Outcomes, Deirdre Lynn Paulson-O'Donovan Aug 2017

The Moderating Role Of Sex On Gender Role Orientation’S Meditation Of Work-Family/Family-Work Conflict And Satisfaction Outcomes, Deirdre Lynn Paulson-O'Donovan

Dissertations

While biological sex has been examined in the work-family interface, findings have been inconsistent in determining if males and females differ in their experiences of work-family conflict (WFC) and family-work conflict (FWC), and how conflict impacts their job, family, and life satisfaction. These inconsistent findings may be due to the changing roles of men and women, as not all men and women are adhering to traditional gender roles. Furthermore, many researchers have used incorrect terminology, indicating that they examined gender, when they actually assessed sex. Thus, the current study’s purpose was to address the shortcomings of the previous literature by …
