Title: Meaningful links: Using network analysis to articulate the structure of personality psychology.
Creator: Hesse, Jared, Lanning, Kevin
Abstract/Description: The current study is presented as an exploratory network analysis of personality psychology using a network composed of 54 source papers and their references. The articles used were papers from the Annual Review of Psychology journal, which dealt with the subject of personality, from 1950 to 2012. References from the source papers were pulled and then mapped onto a network that graphically illustrated the links between different citations. From the network it was possible to deduce, both...
Show moreThe current study is presented as an exploratory network analysis of personality psychology using a network composed of 54 source papers and their references. The articles used were papers from the Annual Review of Psychology journal, which dealt with the subject of personality, from 1950 to 2012. References from the source papers were pulled and then mapped onto a network that graphically illustrated the links between different citations. From the network it was possible to deduce, both visually and statistically, distinctively clustered communities, the relative influence of certain psychologists, and the researchers that bridged disciplinary gaps within the field of personality research. By using digital humanities methods such as network analysis it is possible to better understand and articulate the history and growth of personality psychology.

Title: Gender Stereotypes and Political Ambition.
Creator: Dooley, Connor, Holman, Mirya R.
Abstract/Description: This study analyzes the effects of gender stereotypes on the perception of emotion in hypothetical political candidates. By presenting subjects with various combinations of emotional displays by both male and female candidates, we will be able to see if any gender stereotypes are primed or activated by these displays, and more importantly, the differences in perception of these displays based on the candidate’s gender. For example, if we present the subject with a male candidate who appears...
Show moreThis study analyzes the effects of gender stereotypes on the perception of emotion in hypothetical political candidates. By presenting subjects with various combinations of emotional displays by both male and female candidates, we will be able to see if any gender stereotypes are primed or activated by these displays, and more importantly, the differences in perception of these displays based on the candidate’s gender. For example, if we present the subject with a male candidate who appears aggressive and confrontational, will he be viewed the same way as a female candidate with the same characteristics? Will gender stereotypes cause the female candidate to be perceived more negatively than the male? Previous research has supported the idea that gender stereotypes will effect perception of candidates based on their gender, and this study will help to see if specific stereotypes are primed for application by the subject based on emotional displays.

Title: Synthesis of Podophyllotoxin Derivatives.
Creator: Flint, Madison, Roche, Stéphane P.
Abstract/Description: Podophyllotoxin is a natural aryltetralin lignan compound isolated from plants within the genus Podophyllum. Podophyllotoxin has been under extensive biochemical investigation since the discovery of its biological activity as a strong microtubule destabilizing mitotic agent. Although these antineoplastic compounds have shown significant activity as cancerous cell growth inhibitors, they lack selectivity and are thus extremely toxic to healthy cells.

Show morePodophyllotoxin is a natural aryltetralin lignan compound isolated from plants within the genus Podophyllum. Podophyllotoxin has been under extensive biochemical investigation since the discovery of its biological activity as a strong microtubule destabilizing mitotic agent. Although these antineoplastic compounds have shown significant activity as cancerous cell growth inhibitors, they lack selectivity and are thus extremely toxic to healthy cells. This has led to a recent interest in the synthesis of Podophyllotoxin analogues in hopes of optimizing the biological selectivity and potency of these semi-synthetic derivatives. The objective of my research in the Roche group is to generate a library of these derivatives for subsequent biological assays to determine their potential as chemotherapeutic agents. In total I have synthesized 22 Podophyllotoxin analogues. Of these 22 derivatives, 14 have been biologically evaluated and 4 were observed to possess promising anti-cancer activity and are currently undergoing further evaluation.

Title: Synthesis of Complex Polycyclic Scaffolds Incorporating α-Amino Esters.
Creator: Zorc, Stephen A., Samanta, Shyam S., Roche, Stéphane P., Charles E. Schmidt College of Science
Abstract/Description: In order to keep up with the high demand for biologically active molecules, chemists devised several synthetic strategies to access novel chemical spaces. The two main strategies to construct new scaffolds are to revisit underexploited or forgotten reactions or to devise new transformations. We are exploring a unique and underexploited reaction, the Himbert–Henn cycloaddition, to produce complex molecular scaffolds in a single step (strategy 1).

Show moreIn order to keep up with the high demand for biologically active molecules, chemists devised several synthetic strategies to access novel chemical spaces. The two main strategies to construct new scaffolds are to revisit underexploited or forgotten reactions or to devise new transformations. We are exploring a unique and underexploited reaction, the Himbert–Henn cycloaddition, to produce complex molecular scaffolds in a single step (strategy 1). In a second novel approach, we are modifying the Hantzsch 4-component reaction (4CR) by incorporating an α-amino ester residue to construct new molecules (strategy 2). Both of these reactions have great potential to synthesize novel and chiral molecules from proteinogenic α-amino esters. These unprecedented and complex polycyclic molecules have potential application in medicinal chemistry and natural product synthesis. 4-aza-podophyllotoxins obtained by the Hantzsch-4CR have been proven to be potent as anti-leukemia, anti-colon cancer, and vascular disrupting agents (with nanomolar activity).

It analyzes different ways that spectatorship develops through the division of the film into four sections of which three analyze film from the perspective of Laura Mulvey, Mary Ann Doane, and Linda Williams. These three sections also approach the representation of women as a sociological issue of oppression as discussed by sociologist Patricia Hill Collins. The last section serves as a speculative vision of the future of female representation in Hollywood Film Culture. While this film is critical on the current state of representation, it presents hope for a more equal future.

Show moreThe gopher tortoise (Gopherus polyphemus) is a keystone species which affects the biodiversity that shares its burrow. Habitat fragmentation has led to a decline in populations within southeastern ranges. Haemogregarina (intracellular parasites) have been identified in the blood of gopher tortoises, possibly due to the lack of prescribed fires which are known to kill ticks. However, little is known about their health significance. Two study sites, Blazing Star Preserve (BSP), and Pine Jog Preserve (PJP), differ in their management. The goal of this study is: (1) determine, if any, haemogregarina parasitemia levels of the gopher tortoise population in each site and (2) detect any additional hemoparasite species. We hypothesize that paristemia will be higher in BSP due to increased overcrowding and lack of prescribed fires. This study will benefit current conservation and management practices for gopher tortoises and provide a baseline study for intracellular parasites.

Much of decomposition is attributable to bacterial activity. Identifying a net change in bacterial composition throughout the PMI of a decomposing carcass helps to explain the mechanism of decomposition. Carcasses of four feral swine were placed in cages in direct sunlight, whereby soil samples were taken prior to and following seven days of decomposition. Bacterial DNA was then isolated from the soil samples and amplified via polymerase-chain reaction. Further metagenomic analysis was conducted by an outside agency using 16S ribosomal RNA (rRNA) amplicon sequencing to determine the composition of the bacterial community. A relationship between the stages of decomposition and the anatomy of bacterial communities involved was determined, which helps to elucidate the process of decomposition.

Show moreGopher tortoise (Gopherus polyphemus) populations are diminishing in South Florida due to habitat fragmentation in urban sites. As a keystone species, gopher tortoises have important ecological roles. The goal of this study was to establish a baseline of intestinal parasites in two South Florida populations. One population resides in a fragmented and non-fire maintained site, Blazing Star, and the other in a fire maintained site, Pine Jog. Fire is a natural factor in these habitats reducing canopy cover and killing parasite eggs. The lack of fire in Blazing Star can lead to overgrowth of vegetation, forcing tortoises to crowd where lower vegetation is found. We hypothesize that tortoises from Blazing Star will have a higher degree of intestinal parasites, when compared to those from Pine Jog due to potential crowding. Data is currently being collected, and may provide insight to improve future management and conservation practices.

While these instruments are an essential tool for chemists, students often have limited access to quality instruments due to their high cost. The components used to construct visible spectrometers are moderately inexpensive due to recent technological advances, yet instruments remain expensive. The long term goal of this study is to develop a visible spectrometer accessible to students using readily available and inexpensive components. To accomplish this goal, a prototype instrument was calibrated. Resolution was determined by recording data for samples that absorb visible light at specific wavelengths. To assess the utility of the spectrometer for quantitative analysis, signal intensities were obtained as a function of sample concentration.

Show moreWhales, dolphins, and other marine mammals depend on their hearing to survive, but human technology is now invading their world. Military sonar used by the US Navy to detect submarines emit noises as loud as rocket blasts. These noises infiltrate the ocean and marine mammals get disoriented, have permanent hearing loss, get stranded, or die. With practical safety procedures in place, whales and other marine mammals can be protected from navy sonar. Striking a balance between the nation’s security and the safety of marine mammals can be achieved by passing legislation that takes into consideration both needs. With quality policies such as reducing sonar usage in times of peace in locations that have a high concentration of marine mammals and avoiding sonar use in areas in which they migrate to and feed from, marine mammals can be protected. These safety measures can be passed by using adjudicatory actions.

Cap and trade potentially embodies an effective political compromise that helps protect our planet as well as ensure economic prosperity. Cap and trade sets a limit on greenhouse emissions while allowing business to trade their emissions under free market rules. Cap and trade has been successfully implemented both internationally in Europe, as well as domestically in California. This project looks at implementing a similar model nationally which might lead to advantageous breakthroughs in reducing greenhouse emissions. Moreover, the project discusses the political feasibility and alternative policy pathways and measures that can be taken to pass this policy on a national level.

This study provides information on how urban growth is affecting the Florida Everglades in destructive ways, with a focus on the water in the Everglades. A plethora of water pollutants, such as phosphorous, nitrogen and mercury come directly from human activities associated with urban sprawl. This pollution affects many parts of the Everglades’ natural ecosystem including sawgrass marshes and mangrove swamps, as well as endangered species, such as, the crocodile and Florida panther. This study also addresses limits on chemical pollution that can be placed by the President through executive orders. Overall, the water pollution in the Everglades is destructive in many ways and can be reduced through executive orders from the President to limit the use of chemicals in urban fringe areas.

Yet sprawl is the culprit behind better known issues, such as air pollution and water contamination. The increased use of vehicles and runoff makes sprawled out areas more polluted than compact cities. Because condensing a city is not a workable solution, another way is to improve public transportation. Places that have more sprawl force people to use cars. Improving public transportation by making it more accessible and reliable would encourage people to not use their cars, which saves them money and, in turn, causes less pollution.

In-stream hydrokinetic energy, electricity production from moving currents without the use of dams, has potential for significant power production with technically feasible US electricity production estimated at 14 GW from rivers, 50 GW from tides, and 19 GW from ocean currents; which is equivalent to approximately 17% of 2011 US power production. This work focuses on improving the power production from in-stream hydrokinetic turbines using adaptive torque control, and quantifies increased energy production by comparisons with standard fixed-gain torque control. This research uses numerical modeling to acquire power production estimates under simulated conditions. With these results we can quantify potential energy gains for three representative in-stream hydrokinetic rotor designs.

Show morePentraxin 3 (PTX3) has been demonstrated as a vital biomarker for chronic inflammatory diseases. Decreased plasma PTX3 has been observed in obese populations. However, no studies have examined the impact of obesity on PTX3 reactivity to exercise. Therefore, our study sought to investigate PTX3 plasma response to maximal exercise in obese and normal-weight subjects, and its relationship with insulin sensitivity. Twenty-one subjects (9 obese and 12 normal-weight) were recruited. Plasma PTX3, insulin, and glucose levels were measured before and following exercise. While our results showed lower resting PTX3 levels in obese subjects, exercise elicited similar elevations in PTX3 and insulin sensitivity in both groups. Furthermore, PTX3 area-under-curve (AUC) was correlated with glucose AUC, even when controlled for body mass index and fitness level. These findings suggest that glucose may potentially regulate PTX3 response to exercise. Further investigation is needed to verify the impact of substrate utilization on exercise-induced PTX3 elevation.
