Analysis By Gcms Of Flavone Isomers In Pancreatic Cancer Cells, Daniela Fernandez
Analysis By Gcms Of Flavone Isomers In Pancreatic Cancer Cells, Daniela Fernandez
Undergraduate Student Symposium
Flavone A and B were found to be cytotoxic in pancreatic and colon cancers. Both work in triggering cell apoptosis, although the mechanism and relationship between structure and function are unknown. They are similar in structure, only differing in the location of a hydroxyl and methoxyl group. Flavone B is more planar and lipophilic and, in contrast to Flavone A, has been found to selectively induce apoptosis in less differentiated cancer cells. In this study, the goal was to trace flavone uptake by pancreatic cancer cells and its dispersion inside to determine whether apoptosis is caused in the nucleus or …
Cloning Of Functional And Regulatory Hypothetical Genes In Marine Microbe Roseobacter Denitrificans Och 114, Emily Lazowick, Shira Anteby-Maleh
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 …
Particulate Matter Induces Opportunistic Emergence Of Antibiotic Resistance, Divya Pandya, Arti Patel, Emma Magner
Particulate Matter Induces Opportunistic Emergence Of Antibiotic Resistance, Divya Pandya, Arti Patel, Emma Magner
Undergraduate Student Symposium
It is becoming increasingly recognized that particulate matter in the atmosphere is a significant global health threat and environmental concern. Byproducts from burning of biomass or fossil fuels, polyaromatic hydrocarbons (PAHs), comprise a substantial fraction of particulate matter in many areas. Previous studies have indicated that many PAHs are carcinogenic in mammalian cells and have mutagenic potential in microorganisms such as bacteria. However, the consequences of such mutations in bacteria remain relatively unexplored. In this study, we examine the ability of selected compounds commonly found in particulate matter to generate antibiotic resistant bacteria. We observed that separate treatment with an …
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 …
The Effects Of Wave Exposure, Tidal Height, And Crowding On Cirri And Penis Morphology Of The Acron Barnacle, Tetraclita Stalactifera, Kevin V. Reyes
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 …
George Eliot's The Mill On The Floss As ÃCriture Feminine, Shiri Moshe
George Eliot's The Mill On The Floss As ÃCriture 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
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 …
Source Memory Recognition, Rayna Orsini
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 …

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

Historical Reconstruction Of Population Density Of The Echinoid Diadema Antillarum On Florida Keys Shallow Bank-Barrier Reefs, Donald L. Kissling, William F. Precht, Steven Miller, Mark Chiappone
Marine & Environmental Sciences Faculty Articles
The 1983–1984 caribbean-wide mass mortality of the once ubiquitous long-spined sea urchin Diadema antillarum Philippi, 1845, is one of several factors considered responsible for coral reef change throughout the region. Unfortunately, there is a paucity of pre-mortality event density data for D. antillarum in the Florida Keys, making it difficult to determine pre-1983 population density levels. results from surveys conducted during 1970–1973 in the lower Florida Keys, in shallow (<12 m) fore reef habitats, yielded relatively abundant and widespread D. antillarum densities in qualitative transects at five reefs prior to the 1983–1984 die-off. In quantitative surveys at one reef, Middle sambo reef in 1972, up to 7.9 individuals m …
Concept Mapping As A Data Collection And Analysis Tool In Historical Research, Nancy Baugh, Ann Mcnallen, Michelle Frazelle
Concept Mapping As A Data Collection And Analysis Tool In Historical Research, Nancy Baugh, Ann Mcnallen, Michelle Frazelle
The Qualitative Report
Nurse researchers explored the history of Mary Breckenridge’s Frontier Nursing Service (FNS) during the years 1925 to 1965, to elicit how her experience could inform present day concerns regarding universal access to healthcare. A historical biographical approach informed by critical theory was selected as the methodology. As historical research tends to generate large volumes of data, concept mapping was selected to collect, reduce, organize and interpret data. Additionally, concept mapping can assist researchers to agree on meaning as seen in interrelationships of the data. The final aggregate concept map is a graphic, visual representation of the outcome of this historical …
Development Of Virtue Ethics Based Security Constructs For Information Systems Trusted Workers, John M. Gray, Gurvirender Tejay
Development Of Virtue Ethics Based Security Constructs For Information Systems Trusted Workers, John M. Gray, Gurvirender Tejay
CCE Student and Alumni Proceedings, Presentations, Speeches and Lectures
Despite an abundance of research on the problem of insider threats only limited success has been achieved in preventing trusted insiders from committing security violations. Virtue ethics may be a new approach that can be utilized to address this issue. Human factors such as moral considerations and decisions impact information system design, use, and security; consequently they affect the security posture and culture of an organization. Virtue ethics based concepts have the potential to influence and align the moral values and behavior of Information Systems workers with those of an organization in order to provide increased protection of IS assets. …

Programmed Allee Effect In Bacteria Causes A Tradeoff Between Population Spread And Survival, Robert P. Smith, Cheemang Tan, Jaydeep K. Srimani, Anand Pai, Katherine A. Riccione, Hao Song, Lingchong You
Biology Faculty Articles
Dispersal is necessary for spread into new habitats, but it has also been shown to inhibit spread. Theoretical studies have suggested that the presence of a strong Allee effect may account for these counterintuitive observations. Experimental demonstration of this notion is lacking due to the difficulty in quantitative analysis of such phenomena in a natural setting. We engineered Escherichia coli to exhibit a strong Allee effect and examined how the Allee effect would affect the spread of the engineered bacteria. We showed that the Allee effect led to a biphasic dependence of bacterial spread on the dispersal rate: spread is …

Teacher Technology Narratives: Native Hawaiian Views On Education And Change, D. Lilinoe Yong, Ellen S. Hoffman
Teacher Technology Narratives: Native Hawaiian Views On Education And Change, D. Lilinoe Yong, Ellen S. Hoffman
The Qualitative Report
Narrative inquiry is a method by which "silenced voices" may be heard. In this study, eight Native Hawaiian teachers share their experiences of the Hawaiian Language Immersion Program (HLIP), or Papahana Kaiapuni, within the Hawai‘i public school system. The teachers describe change over time in HLIP with a focus on technology and their perceptions of how it has enhanced preservation of the Hawaiian language. By giving voice to their views on indigenous culture and teaching, the stories provide a rich and nuanced view of growth and school reform as framed by the teachers' own words. Themes of commitment to students …

Graduating Black Males: A Generic Qualitative Study, Edward E. Bell
The Qualitative Report
Black males face a difficult educational battle. Across America, graduation statistics for Black males are sobering. The purpose of this study was to explore why Black males drop out of school and to examine the current employment status of the study participants. The research took place in rural North Carolina. Fifteen Black American male high school dropouts took part in a snowball sample. This study was qualitative and used open and axial coding. Findings from this study may provide guidance and directions for school and community leaders to help Black males stay in school through graduating.

Key to predicting impacts of predation is understanding the mechanisms through which predators impact prey populations. While consumptive effects are well-known, non-consumptive predator effects (risk effects) are increasingly being recognized as important. Studies of risk effects, however, have focused largely on how trade-offs between food and safety affect fitness. Less documented, and appreciated, is the potential for predator presence to directly suppress prey reproduction and affect life-history characteristics. For the first time, we tested the effects of visual predator cues on reproduction of two prey species with different reproductive modes, lecithotrophy (i.e. embryonic development primarily fueled by yolk) and matrotrophy …

Human obesity has been linked to genetic factors and single nucleotide polymorphisms (SNPs). Melanocortin-4 receptor (MC4R) SNPs have been associated with up to 6% frequency in morbidly obese children and adults. A potential therapy for individuals possessing such genetic modifications is the identification of molecules that can restore proper receptor signaling and function. These compounds could serve as personalized medications improving quality of life issues as well as alleviating diseases symptoms associated with obesity including type 2 diabetes. Several hMC4 SNP receptors have been pharmacologically characterized in vitro to have a decreased, or a lack of response, to endogenous agonists …
Culturometrics: A Constructionist Philosophy For Humanistic Inquiry In Qualitative Identity Research, Béatrice Boufoy-Bastick
Culturometrics: A Constructionist Philosophy For Humanistic Inquiry In Qualitative Identity Research, Béatrice Boufoy-Bastick
The Qualitative Report
Culturometrics is a new person-centred research philosophy that has shaped new tools for measuring and revealing the subjectivities of cultural identities. By focusing on tractable processes of identity communication rather than attempting to categorise the infinitely variable forms of identity outcomes it has developed intuitively acceptable computationally simple bridges across the qualitative /quantitative research divide. By reframing social constructs as cultural identities and categorising cultural groups by the fluidity of their membership it has extended the remit of traditional qualitative research. This paper gives a brief overview of the humanistic intentions of Culturometrics that underpin its objective methods for measuring …

Understanding The Linkages In Organisational And Human Relations: A Review Of Social Network Analysis, Loum S.L. Constantine
Understanding The Linkages In Organisational And Human Relations: A Review Of Social Network Analysis, Loum S.L. Constantine
The Qualitative Report
This article proposes a methodological stance, an Interpretative Phenomenological Analysis (IPA) of participants’ drawings as one that is useful for research into people’s experiences of seizure consciousness. Using empirical examples located in an original, larger study, this article offers a rationale for, and illustrates the analytic potential of, this combination. It also considers that elicitation interviewing techniques and methods from the field of neuro-phenomenology could take this work further in terms of deepening the analysis by reaching people’s pre-reflexive conscious experiences. This theoretical and practical combination has the potential to develop this work significantly.

Do Parent And Teacher Ratings Of Behavior Measure What They Are Intended To Measure?, Phillip Martin
Theses and Dissertations
This study involves an examination of the neurocognitive correlates of subscales of the Conners' Rating Scale - Revised (CRS-R), an ADHD behavioral rating form, in both a child (n=72) and an adolescent (n=49) sample. While both behavioral rating forms and neuropsychological measures are commonly employed in pediatric clinical evaluations, these two forms of assessment do not generally converge as expected. The purpose of the current research was to examine and compare the abilities of intellectual, academic, attentional, and executive skills to account for variance in parent and teacher ratings of behavior across two pediatric age groups in a clinical setting. …
