Many species considered exotic, by both biological definition and social construction, have been introduced into South Florida. These species compete for resources with native species and with each other. In this study, I surveyed the John D. MacArthur Campus of Florida Atlantic University in Jupiter Florida during spring and fall of 2005 to determine the assemblage dynamics of several exotic herpetofauna species, primarily the nocturnal Wood Slave gecko (Hemidactylus mabouia), the Indo- Pacific gecko (H. garnotii), and the diurnal Cuban brown anole (Anolis sagrei). I found that the more recently established (H. mabouia) was out-competing (H. garnotii) on most of the buildings being surveyed. The study also showed that the Cuban treefrog, (Osteopilus septentrionalis) population affected the gecko populations significantly. (A. sagrei) was the primary anole found on campus, with sightings of (A. carolinensis) the native Florida green anole, being rare.

Every day, business owners make important decisions trying to increase productivity. Smaller, family-owned companies, however, have a financial disadvantage over larger corporations. Through the analysis of one small business, Gardens Pool Supply, we provide the owners with answers to questions on how to reduce costs and increase profits.

Bioprospecting, the search for useful compounds in nature, has led to the discovery of many important pharmaceuticals. Most current bioprospecting efforts work with chemicals derived from marine invertebrates and terrestrial plants. I looked for useful compounds in a relatively unstudied source, the venom of Crematogaster ants, using Gas Chromatography-Mass Spectroscopy (GC-MS). Further studies can more accurately identify these chemicals using High Pressure Liquid Chromatography (HPLC) and Nuclear Magnetic Resonance (NMR).

Difficulty in communicating internal states may interfere with medical assessment of pain conditions. Individuals who score high on an assessment measure of a construct called alexithymia have difficulty in describing and/or identifying emotions. Both diffuse and low verbal communication styles have been related to alexithymia in chronic pain patients. Alexithymia has also been linked with pain intensity and various chronic pain conditions. As yet, research has not examined whether alexithymia and acute pain are related. The current research examined high-functioning individuals with chronic, acute, or no pain. No difference in alexithymia levels was found between the groups. However, pain intensity was related to difficulty in identifying feelings, and participants who scored high in alexithymia produced a low number of words per sentence in pain descriptions.

In Nathaniel Hawthorne's The Scarlet Letter and its preface, "The Custom- House," the author himself and Pearl Prynne are characters who engage in travel, escaping the restrictiveness imposed onto them by their hometowns and finding greater creative freedom elsewhere. Their journey, however, is not necessarily physical but rather creative. Hawthorne and Pearl employ writing and imaginative thinking, respectively, in order to characterize Salem and Boston as foreign locations through which they may tour. The two are what Hawthorne calls "citizen[s] of somewhere else," although they have not departed from their homes yet. By considering how "The Custom-House" relates to The Scarlet Letter based on the themes of travel and home, a new interpretation arises about Hawthorne's book as well as his definition of the American romance, which posits that a person may use creativity in order to find his or her place both within and away from the community.

The gopher tortoise, Gopherus polyphemus, is a threatened species native to the southeastern United States. The breeding season of G. polyphemus is reportedly from April to June. However, out of season hatchlings in Jupiter, Florida, suggest that in South Florida, the very southernmost part of the gopher tortoise's range, the warmer climate allows a longer period of reproduction or a year-round breeding season. My research sought to find evidence for an extended breeding season and to collect fecundity data on the South Florida tortoises by capturing female tortoises and X-raying them at different times of the year to check for the presence of eggs. Although I found no conclusive proof of an extended breeding season, I present additional circumstantial evidence for it, as well as information regarding the fecundity of tortoises in the spring.

The academic debate on gender and migration has missed some of the key factors that impact women's lives and communities of origin. Interviews conducted in Jacaltenango, a Mayan sending community in Guatemala, suggest that while the migration of a spouse does bring substantial financial benefits there are significant individual and social costs that result from migration. More importantly, the interviews uncovered the crucial impact of transnational gossip on women's lives, a feature that has been absent in previous academic treatments of gender and migration. Transnational gossip has exacerbated the negative effects of migration for women in migrant-sending locations, pushing women to stay in the "private sphere" and serving as a form of social control that keeps women from actively participating in their communities. For many women, long periods of time living apart from their spouses combined with fears about transnational gossip have brought severe loneliness, anxiety, health problems and even seclusion. This phenomenon is helping define the contemporary social structures of Jacaltenango, and represents one of the most important effects of migration in terms of the lived reality of spouses and families of the predominantly male immigrants who leave Mayan communities in Guatemala to seek work in the United States.

Terror Management Theory posits that induced death-related cognitions lead to anxiety. To relieve anxiety, individuals may bolster their self-esteem or current cultural worldviews. The current study hypothesizes that induced thoughts of social connectedness will be an anxiety-buffering mechanism that will reduce the need to defend one's worldview. Participants watched one of two films which were intended to either induce social connectedness or have no effect on the individual. Each participant watched a short film clip then completed measures pertaining to moral transgressions, affiliative and agentic extraversion, self-esteem, and positive and negative affect. Females who were high on affiliation were found to defend their worldviews more often than males high on affiliation following the social connectedness induction. The experimental (42-Up) condition showed lower levels of punitiveness than the control (K-Web) condition.

Many critics and readers assume that Tess of the d'Urbervilles is simply the tragedy of a ruined country maiden and that the sexually-driven scenes are the most important aspects of the novel. In my thesis, however, I argue that Thomas Hardy created a novel centered on his complex heroine, Tess, not on simplistic notions of sexual ruination and sensational plot developments. In other words, Tess is an autonomous, detailed character who cannot be relegated to the usual stereotypes of Virgin, Whore, Mother, etc. Through my reading, we gain a greater understanding of the novel as a whole, instead of as a fractured, deterministic, and plot-driven tragedy. I begin my argument by examining Hardy's subtitle, "A Pure Woman," asserting that our focus should be on the word "Woman" and Tess's subjectivity, not reductive concepts of "purity" or chastity. In Chapter Two, I examine two significant scenes that occur in Alec's carriage, showing how many critics' readings underestimate Tess as helpless, and arguing that she fights against her oppressor in covert ways. My third chapter continues this defense of Tess by critiquing the critical debate surrounding the sexual encounter in "The Chase". I posit that the entire debate is flawed and that Tess should be defined based upon her actions and not simply her sexuality. Lastly, in my conclusion I present a broader defense of Tess of the d'Urbervilles, in which I assert that the ambiguous plot scenes in Tess are conscious attempts by Hardy to subvert traditional assumptions about what is important in a novel. My goal in this thesis is to critique popular but simplistic interpretations of Tess of the d'Urbervilles which diminish Tess's role; instead, I emphasize the way her character, in the words of critic Kathleen Blake, "invites but frustrates oversimplification."

This thesis presents an examination of the trope of photography in E. L. Doctorow's latest novel, The March, which takes General Sherman's march through Georgia and the Carolinas as its subject matter. The Civil War, as the first major American military conflict to be photographed, is the perfect vehicle for the novel's meditation upon the representation of significant political and cultural events. As this paper argues, photography functions in the novel as a metaphor for visual culture in general. In particular, I argue that the discrepancies which the novel posits between the photographic record and lived experience function to trouble notions of media transparency. As the novel suggests, the popular conception of photography, which constructs it is an irreproachable and infallible medium, has lent itself to political manipulation. Thus, through photography, the novel depicts history as the conventional framing of events for posterity, not as a comprehensive record of events.
