Cognition presents evolutionary research with one of its greatest challenges. Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by differences in social and dietary complexity. However, no study has integrated the experimental and phylogenetic approach at the scale required to rigorously test these explanations. Instead, previous research has largely relied on various measures of brain size as proxies for cognitive abilities. We experimentally evaluated these major evolutionary explanations by quantitatively comparing the cognitive performance of 567 individuals representing 36 species on two problem-solving tasks measuring self-control. …

Risk Factors Associated With Enteric Septicemia Of Catfish On Mississippi Commercial Catfish Farms, Fred L. Cunningham, S. W. Jack, David Hardin, Robert W. Wills

United States Department of Agriculture Wildlife Services: Staff Publications

A gram-negative bacterium, Edwardsiella ictaluri, is the cause of enteric septicemia of catfish (ESC), which is one of the most prevalent bacterial diseases in farm-raised catfish. The objective of this study was to identify risk factors associated with ESC mortalities and are reported by farm personnel. To identify risk factors a catfish management database was developed. The odds ratios (OR) of the final multivariable logistic regression model were: (1) volume of the pond (OR, 0.56), (2) interval from harvest until a mortality event (OR, 1.49), (3) interval from stocking until a mortality event (OR, 0.52), (4) nitrite measured within 14 …

Patterns And Mechanisms Of Heat Transport In The Northern Denver Basin Nebraska, South Dakota And Wyoming, Aaron T. Ochsner

Theses and Dissertations

Finite difference simulations of the hydrothermal system of the northern Denver Basin are suggestive of a correlation between anomalous heat flux and the presence of faults and structural lineaments mapped in the region. Geothermal, hydrogeological, lithological, and structural data available for the northern Denver Basin were compiled and analyzed in an effort to determine the hydrothermal mechanisms responsible for observed heat flow anomalies in the study area. Measurement of thermal conductivity was conducted for 82 solid core samples and 60 unconsolidated samples from drill cuttings, yielding a harmonic mean thermal conductivity value of 1.52 ± 0.91W m-1 K-1 for the …

The Establishment Of A Fibroblastic Cell Line From Yellow Perch (Perca Flavescens) And Its Potential Applications In Toxicology, Katelin W. Spiteri

Theses and Dissertations (Comprehensive)

This thesis describes the establishment, characterization and potential toxicological applications of YPF5, a yellow perch cell line. YPF5 is a fibroblastic cell line derived from the caudal fin of yellow perch. This cell line has been maintained for over 2 years. Cultures have been passaged over 60 times, and successfully cryopreserved and thawed. YPF5 is grown at room temperature in Leibovitz-15 (L-15) media, supplemented with 10% fetal bovine serum and 3% penicillin-streptomycin. The origin of YPF5 has been confirmed as Perca flavescens through “DNA Barcoding” and reaffirmed through Karyotyping (2n = 48) as per literature reported karyology for percidae including …

Investigating The Persistence And "Naturalization" Potential Of Salmonella In Non-Host Environments Using Culture-Based And Molecular-Based Fingerprinting Techniques, Robyn L. Morrison

Theses and Dissertations (Comprehensive)

Recent studies suggest the potential exists for enteric microorganisms to become “naturalized” to the complex natural environment through maintenance of their populations via replication and adaptation to the stress imposed by their external surroundings. The aim of this research was to better understand the potential for antimicrobial resistant (AMR) Salmonella to become “naturalized” and the physiological adaptations that allow for non-host survivability as reflected by AMR and community profiling. To better elucidate the prominent factors leading to a “naturalized” condition, two approaches were taken: 1) survey-based field research to gain perspective on the prevalence of AMR Salmonella isolated from variously …

Musical Chairs In A Boreal Peatland: How Permafrost Thaw Reverses Successional Processes, Mélissa M. Fafard

Theses and Dissertations (Comprehensive)

The current climate trends indicate amplified high latitude warming. Boreal peatlands can be found within those high latitudes and have important functions hydrologically, ecologically and also in terms of carbon cycling. Peatland’s are wetlands that have accumulated more than 40 cm of peat and can range from minerotrophic fens to ombrotrophic bogs. Naturally, a rich fen can be converted to a bog once groundwater sources are cut off by Sphagnum spp. In areas underlain by discontinuous permafrost, landscape changes are occurring particularly rapidly as the permafrost there is sensitive to both vertical and horizontal thaw. The purpose of this thesis …

A Computational Study Of Small Gold Clusters With H2s, Thiols, H2o, And Alcohols, Silvija C. Smith

Theses and Dissertations (Comprehensive)

Alkane thiols, RSH, are commonly used in aqueous solution to stabilize and prevent aggregation of gold clusters, Au_n. Initially a RSH-Au_n complex is formed and, subsequently, there is hydrogen atom transfer to form a RSAu_nH complex. We examine the rate of this reaction for small neutral gold clusters, with n=1-2 and short-chain thiols with R = H, CH₃, and CH₃CH₂, using transition state theory. The comparison of DFT (with the functionals, BP86 and M06-2X), and MP2 was performed. A pseudopotential was employed to account for the large relativisitic effects …

Causes And Consequences Of Female Mate Choice In Drosophila Melanogaster: A Hemiclonal Analysis, Hannah Me Tennant

Theses and Dissertations (Comprehensive)

One of Darwin’s greatest questions, the reason why females prefer elaborate sexually selected male traits and displays, was elucidated by the Fisherian coevolution of male traits and female preferences. While variation in male attractiveness and ornamentation has received much attention, there has been little attempt to evaluate the causes and consequences of intraspecific variation in components of female preference. Furthermore, demonstrating a genetic basis to female preference does not answer the question of how within-population genetic variation is maintained.

Understanding the sources of variation in potential mating interactions between males and females is important because this variation determines the strength …

Improving Preschoolers' Mathematical Performance: The Nature Of Spatial Input By Early Childhood Educators, Joanna Zambrzycka

Theses and Dissertations (Comprehensive)

Early spatial abilities are related to a number of positive academic outcomes such as success in geometry and chemistry domains in later adulthood (Delgado & Prieto, 2004; Stieff, 2007). Further, more advanced spatial abilities in early adolescence predicts engagement and success in science, technology, engineering, and mathematics (STEM) occupations in later adulthood (Shea, Lubinski, & Benbow, 2001). There is a wealth of research that links spatial abilities to overall mathematics achievement in both adults (e.g., Casey, Nuttall, Pezaris, & Benbow, 1995) and children (e.g., Holmes, Adams, & Hamilton, 2008).

Adult input positively impacts children’s subsequent spatial and mathematical development. Parental …

Pro-Anorexia/Bulimia Interactions Online: Problematizing Complex Cultural Phenomena, Nicole D. Schott

Theses and Dissertations (Comprehensive)

In the West, and increasingly globally, individuals, particularly women, are fixated on weight loss, driven by the goal of achieving a culturally-desired, and aggressively marketed, "skinny" female physique. There are online forums where individuals refer to themselves or their eating disorders as "pro-ana" and "pro-mia". Individuals who post on these sites both align with, and challenge, what medical and mental health professionals define as serious mental health problems that result in severe, sometimes fatal, medical complications. This thesis specifically focuses on interactions with, and within, the pro-ana/mia culture on the social media websites Tumblr and YouTube. Over sixteen months, and …

Microbial Community Characterization And Pathogen Profiling Of Land-Based Aquaculture Systems Using Culture-Based And Molecular-Based Fingerprinting Techniques, Nicole S. Kteily

Theses and Dissertations (Comprehensive)

The growing worldwide demand for fish production has prompted research towards intensive aquaculture. Innovative system designs, such as recirculating and flow-through aquaculture systems, have been developed to improve the efficiency and sustainability of intensive aquaculture practices. These LBAS systems exhibit a wide range of spatial and temporal heterogeneity. Although such heterogeneity suggests the potential for culture water to support a diverse and spatially complex assortment of microorganisms, there is a lack of information regarding the overall diversity and composition of microbial communities (including pathogens) in the different compartments of these systems. To better understand the diversity and functionality of microbial …

Diversity And Evolution Of The Multicellular Protuberances In Cuscuta (Convolvulaceae) And The Function Of The Stomatiferous Protuberances In Cuscuta Subgenus Grammica, Courtney J. Clayson

Theses and Dissertations (Comprehensive)

Cuscuta (Convolvulaceae), also known as the dodders, is a holoparasitic genus comprised of ca. 200 species grouped into four subgenera: Monogynella, Cuscuta, Pachystigma, and Grammica. The presence of unique multicellular structures, referred to as stomatiferous protuberances (SPs), was reported on the stems of subgenus Grammica over a century ago and was forgotten until similar SPs were observed on the flowers of several new Grammica species. The stems and flowers were examined in 136 Cuscuta taxa, and SPs were discovered on all of the haustorial stems of the species in the subgenus Grammica, as well as …

A Feasibility Study On The Implementation Of Satellite-To-Satellite Tracking Around A Small Near-Earth Object, Christopher Joseph Church

Theses and Dissertations

Near-earth objects (NEOs) are asteroids and comets that have a perihelion distance of less than 1.3 astronomical units (AU). There are currently more than 10,000 known NEOs. The majority of these objects are less than 1 km in diameter. Despite the number of NEOs, little is known about most of them. Characterizing these objects is a crucial component in developing a thorough understanding of solar system evolution, human exploration, exploitation of asteroid resources, and threat mitigation. Of particular interest is characterizing the internal structure of NEOs. While ground-based methods exist for characterizing the internal structure of NEOs, the information that …

Ratings Lead You To The Product, Reviews Help You Clinch It? The Dynamics And Impact Of Online Review Sentiments On Products Sales, Nan Hu, Noi Sian Koh, Srinivas K. Reddy

Research Collection Lee Kong Chian School Of Business

It is generally assumed that ratings are a numeric representation of text sentiments and their valences are consistent. This however may not always be true. Using a panel of data on over 4000 books from Amazon.com, we develop a multiple equation model to examine the inter-relationships between ratings, sentiments, and sales. We find that ratings do not have a significant direct impact on sales but have an indirect impact through sentiments. Sentiments, however, have a direct significant impact on sales. Our findings also indicate that the two most accessible types of reviews - most helpful and most recent - play …

Anticipated Regret In Time-Based Work-Family Conflict, Jessica Bagger, Jochen Reb, Andrew Li

Research Collection Lee Kong Chian School Of Business

The primary purpose of this research was to investigate the role of anticipated regret in time-based work-family conflict decisions.

A total of 90 working parents responded to a decision making problem describing a time-based conflict between a work event and a family event. Participants' preference for which event to attend constituted the dependent variable. Independent variables were participants' work and family centralities. Anticipated regret for choosing the work option and anticipated regret for choosing the family option were measured as hypothesized mediators.

Structural equation modeling revealed that anticipated regret for choosing the family option mediated the relationship between work centrality …

Refocusing The Lens: Singapore's Private Enterprises In China, Caroline Yeoh, Wilfred Pow Ngee How, Ye Zhang

Research Collection Lee Kong Chian School Of Business

In recent years, financial and political instabilities have cooled economic growth in many regions. Even in this context, however, areas of strong growth remain; none, arguably, more prominent than ever-developing and increasingly affluent China, which is today a vastly different environment than even several years ago. More than ever, a wealth of opportunity subsists in this ancient land – and businesses must be able to adapt and seize these opportunities. Thus we turn towards Singapore private enterprise in China, to study once more the efficacy of the city-state's internationalization strategies in the context of the private enterprises which must eventually …
