Enculturation Through Ambiguity: Morality And Meaning In Children's Tv Shows, Khadija Chowdhury

Undergraduate Student Symposium

It is easy to blame excessive “screen time” for the educational and behavioral difficulties that children face. And with children under the age of 6 watching an average of 2 hours of screen media a day, and older children averaging 4 hours a day, such practices deserve our attention. Children’s television shows in particular often get criticized for their thin content, gross humor, and “passive” viewing. But television shows do teach values and social conventions. And such enculturation need not be looked at as passive. As Haas and Flower write, “‘meaning’ does not exist in a text but in readers …

Predicting Porphyrin Basicity Using Semi-Empirical Methods, Haley Mckissack

Undergraduate Student Symposium

Porphyrins are macrocycles found in many natural compounds. The changes in energy between the protonated (dication) and free base porphyrins were determined using molecular modeling. The data obtained was then compared to experimental enthalpy values. The porphyrins analyzed were octaethylporphyrin, octaethyltetraphenylporphyrin, tetraphenylporphyrin, and tetra-[2]-pentylporphyrin. Molecular mechanics was employed to optimize each porphyrin, and semi-empirical calculation methods RM1 and PM3 were subsequently utilized to test the conformational energies of the protonated and deprotonated porphyrins. The semi-empirical PM3 method was best for analysis of energy changes among the porphyrins; although the obtained values did not exactly match experimental values, the trends of …

Reality And Rhetoric: U.S. Foreign Policy And Egypt's Arab Spring, Shiri Moshe

Undergraduate Student Symposium

The Arab Spring, a series of revolutionary civil uprisings that swept across the Middle East and North Africa in 2011, has drastically transformed the Egyptian political sphere. Egypt, designated a major nonNATO ally by the United States (Foreign Assistance Act, 1989), is one of the largest recipients of U.S. economic and military assistance. Its domestic developments have consequently been of major interest to the Obama administration. Drawing from relevant executive statements and releases, major news media and Congressional Research Service reports, and peer-reviewed publications, my research delineates the public rhetoric and actions of the U.S. executive office towards the state …

Cloning Of Functional And Regulatory Hypothetical Genes In Marine Microbe Roseobacter Denitrificans Och 114, Emily Lazowick, Shira Anteby-Maleh

Undergraduate Student Symposium

The goal of this project is to clone four selected genes from the marine microbe, Roseobacter denitrificans, which plays a significant role in the dynamic and biogeochemical interactions of oceaninc ecosystems. Two of these genes, rodA and cheY, which have known functions involved in structure, development, motility, and chemotaxis, will be used as controls to elucidate the functions of two hypothetical genes, "N-AcGlu" and rhaI, which are believed to be involved in sugar metabolism. R. denitrificans genomic DNA was isolated via the QIAgen DNA Purification Kit, and Restriction Fragment Length Polymorphism of 16S ribosomal DNA with the …

George Eliot's The Mill On The Floss As ÉCriture Feminine, Shiri Moshe

Undergraduate Student Symposium

In her influential treatise “The Laugh of the Medusa,” poststructuralist French theorist Helene Cixous explores the notion of text marked by gender, and notes its importance in subverting the patriarchal structures that perpetuate female oppression within the dominant, phallo-centric social and political order. By analyzing the criterions set by Cixous, and applying them to George Eliot’s The Mill on the Floss’, my research demonstrates that Eliot’s novel firmly adheres to several key poststructuralist, feminist principles, and contends that it can thus be viewed as an example of écriture feminine, or a fluid, subversive feminist work, which highlights socially constructed …

Infection Rates Of Asian Fish Tapeworm (Bothriocephalus Acheilognathi) In Three Commercially Available Poeciliid Fishes (Molly, Platy, And Swordtail), Amrita Choithani

Undergraduate Student Symposium

The Asian fish tapework (Bothriocephalus acheilognathi) has been widely introduced beyond its native range into several localities across the USA, largely via the aquaculture of imported Cyprinids. This tapeworm can infect a wide range of fishes, and is considered pathogenic, particularly in small-bodied or juvenile fishes. Consequently there is significant concern over the potential of this parasite to escape from aquaculture sites and subsequently infect native fishes. Fish acquire B. acheilognathi when they consume infected copepods, which acquire the parasite when they consume larvae recently hatched from the feces of infected fishes. Thus, fish cultured in ponds and …

Mechanism Of Apoptosis Induced By Phycocyanin In Lncap And A549 Cancer Cells, Haley Nation, Omar Garcia, Omar Viqar

Undergraduate Student Symposium

Phycocyanin is a pigmented protein found in cyanobacteria produced by aphanizomenon flos-aquae (a freshwater species of blue-green algae) and spirulina. Phycocyanin (PC) has been researched extensively in the last twenty years because of its anti-cancer properties. Despite numerous critical findings, the anti-cancer mechanism for how PC induces apoptosis in cancer cells is still unknown.

The purpose of our experiment was to determine the uptake of PC by cancer cells and then study different mechanisms of apoptosis. PC naturally emits red florescence, which was utilized to verify the uptake by LNCaP prostate cancer cells. We were able to determine that …

Source Memory Recognition, Rayna Orsini

Undergraduate Student Symposium

This experiment examines how timing impacts source memory. Previous studies have found that preverbal infants may remember events, but cannot retroactively apply language to describe the event (Simcock and Hayne, 2002). Previous experiments tested individuals’ source memory of symbols and animals that they learned the names of either before or after they encountered them. Individuals better recognized symbols and animals they had learned the names of before they encountered them rather than after, leading us to believe that timing of learning affects source memory recognition (Collins et al., 2011). However, poor performance on the stimuli learned after they were encountered …

Tail Spine Characteristics Of The Yellow Stingray, Urobatis Jamaicensis (Order: Myliobatiformes), Of Broward County, Florida, Ana Rehman

Undergraduate Student Symposium

The barbed spine of the yellow stingray, Urobatis jamaicensis, has a unique architecture and histology. The spines are stiletto-shaped and flattened with lateral serrations that point backwards. Venom-secreting glandular cells incased in by integument run along two longitudinal grooves for the length of the spine. Urobatis has one or more barbs (modified dermal denticles) located on the dorsal side of the ray's tail, which often is used for defense. Previous research has reported the existence of tail spine asymmetry by geography, sex and age in 12 species of stingrays (Schwartz, 2007), This study examined tail spine length and number …

Tetraphenylporphyrin Derivatives And Octalkyl Porphyrin Interactions In Cancer Cells, Biana Modilevsky

Undergraduate Student Symposium

Synthetic porphyrin molecules are commonly studied as photosensitizing agents in photodynamic therapy as a form of cancer treatment. The porphyrin molecules target cell organelles to induce cellular apoptosis, or navigate toward the cellular membrane, causing tissue necrosis. This porphyrin activity is primarily undetectable and only activated under the exposure of light. The chemical structure and properties of porphyrin compounds have varying effects on their success and viability in this treatment. The study of tetraphenylporphyrin derivatives and octalkyl porphyrin compounds can be implemented in finding suitable compounds for this technique.

The Effects Of Wave Exposure, Tidal Height, And Crowding On Cirri And Penis Morphology Of The Acron Barnacle, Tetraclita Stalactifera, Kevin V. Reyes

Undergraduate Student Symposium

Exposure to wave action can affect the feeding appendages (cirri) and penis morphology of intertidal barnacles. We tested several hypotheses of morphological differences in the cirri and penises of the barnacle Tetraclita stalactifera at different heights of the intertidal zone, on wave exposed and wave protected sites and at different levels of crowding. We sampled eight sites varying for these properties and found that barnacles from higher positions in the intertidal zone had thicker cirri than those from lower positions. In wave exposed sites, cirri were shorter and thicker than in protected sites. Increased thickness may be an adaptation to …

The Qualitative Report Books

Edward Bliss Emerson (1805-1834), a younger brother of the renowned essayist and poet Ralph Waldo Emerson, lived in the Caribbean for the final three years of his life. His journal and letters are a rich manuscript source for the history of the Danish Virgin Islands (1831-1832) and Puerto Rico (1831-1834). The texts also reflect the contemporary political and cultural situation in the United States, and Edward's search for health, economic independence, intellectual stimulation and metaphysical fulfillment.

These writings ignited an intellectual passion in José G. Rigau-Pérez, a physician, medical epidemiologist, and historian in Puerto Rico. Furthering access to these unique …

The Fda Funding Crisis, Judith Alphonse, Sireesha Bellam, Marlene Fernandez, Anishka Gilbert, Lauren Roper, Antonia Zapantis, Robert C. Speth

HPD Articles

The role of the Food and Drug Administration (FDA) is to ensure the safety of prescription and nonprescription drugs, dietary supplements, and the food supply, representing more than 20% of US consumer spending. The increased need to monitor imported drugs, drug products and foods, drug shortages, and compounding pharmacies bring the adequacy of FDA funding into question. Performing even at status quo cannot be accomplished if responsibilities increase without equitable funding increases: both from the federal government and fees imposed on FDA-regulated industries. Additionally, scientific advancement, new legislation, and new industries are continually increasing the FDA workload, necessitating commensurate budget …

Transfusion-Related Acute Lung Injury (TRALI) is a rare, life-threatening hazard of blood transfusion. In the intensive care unit, 37% to 44% of admitted patients are transfused with at least one blood component. The opportunity for health professionals and students from nursing, respiratory care, and clinical laboratory science to interact directly with patients receiving a blood transfusion is likely to present itself on a daily basis. It is imperative for those caring for critically ill patients to be fully aware of the clinical signs of TRALI and have knowledge in the prevention and treatment of this clinical syndrome. Common clinical signs …

Consideration For Lumbar Disc Degeneration And Herniation In Sports, Ziva Majcen, Tanja Rauter Pungartnik, Nejc Sarabon

Internet Journal of Allied Health Sciences and Practice

Lower-back related injuries in an athletic population are common and may have severe implications for the athletes sporting career. The focus of this work was to review epidemiology, intervention strategies, and recommendations for return to practice and competition for athletes with lumbar disc degeneration and herniated disc. Conservative treatments for discogenic degeneration and lumbar spine herniation are generally sufficient for athletic populations to restore functional movement. Athletes that fail to respond to conservative measures may consider lumbar discectomy, with high levels of return to pre-competition levels observed following effective surgery. Surgical procedures such as spinal fusion and disc replacement require …

Increase Of Excavating Sponges On Caribbean Coral Reefs: Reproduction, Dispersal, And Coral Deterioration, Andia Chaves-Fonnegra

HCNSO Student Theses and Dissertations

Coral reefs ecosystems are deteriorating and facing dramatic changes. These changes suggest a shift in dominance from corals to other benthic organisms. Particularly in the Caribbean Sea, with corals dying, sponges have become the leading habitat-forming benthic animals. However, little is known about what life-history traits allow organisms to proliferate in a marine system that is undergoing change. Thus, the objective of this dissertation was to try to understand the current increase of encrusting excavating sponges on deteriorating Caribbean coral reefs through the study of reproduction, recruitment and dispersal potential of the widely distributed and currently expanding species, Cliona delitrix …

Combined Gut Content-Stable Isotope Trophic Analysis And Satellite Tagging Of The Pelagic Stingray Pteroplaytrygon Violacea (Bonaparte, 1832) From The Western North Atlantic Ocean, Tiffany A. Weidner

HCNSO Student Theses and Dissertations

The pelagic stingray, Pteroplatytrygon violacea, is a bycatch species in the global pelagic longline fishery. However, little research has been conducted on its basic biology, including prey composition, trophic positioning, and habitat utilization. Descriptions of the habitat utilization have largely been through indirect analyses of catch rates in commercial fisheries, which also provided no information on actual behaviors. The first chapter of this thesis will describe the habitat utilization and behavior of four individual pelagic stingrays using electronic tagging technology. Prior diet descriptions were hampered, in part, by low sample sizes and accordingly provided little information on the ecological …
