The Role Of Cheating Behavior And Personality Traits In Deception Detection Ability, Joshua Braverman
Undergraduate Student Symposium
In this study we examined the relationship that propensity for cheating, as well as several other personality traits, have with deception detection ability. Participants were first administered a behavioral measure of their tendency to cheat on a short mathematics exam, as well as a measure of anger toward hypothetical cheaters. Second, participants viewed a series of video clips of NSU students making truthful and deceptive statements; participants attempted to discriminate between truthful and deceptive statements, and also rated the personality traits of the NSU students. Third, participants attempted to discriminate between truthful and deceptive statements in 8 media clips of …
Using Engineered Bacteria To Explore Biological Invasions, Josue Conde, Neil Thackar
Using Engineered Bacteria To Explore Biological Invasions, Josue Conde, Neil Thackar
Undergraduate Student Symposium
One critical ecological challenge is to circumvent invasion from non-indigenous organisms. Studying the factors that affect the ability of a non-indigenous species to colonize and spread into a new territory is very challenging due to multiple confounding factors. Synthetic biology is often not subject to these confounds, and thus we utilize it to explore factors that allow invasive species to successfully invade a new area. Specifically, we use engineered bacteria that are programmed to have an Allee effect, a fundamental growth dynamic that is observed in most invasive species. Using these bacteria, we take a two-pronged approach. First, we examine …

Development Of A Library Of Synthetic Compounds With Multiple Pharmacophores, Alissa Svedberg, Zachary Galloway, Akshay Naraine
Undergraduate Student Symposium
It is known that chalcones and pyrazolines possess antibacterial and antifungal activity; the overall goal of this project was the development of a library by synthesizing novel hybrids containing both chalcones and pyrazolines. The hybrids may show antibacterial efficiency against S. aureus, E. coli, and Candida albicans. Oxindole derivatives have shown previous biological activity in combating bacteria such as S. aureus and E. coli, but using N-alkylation, the novel derivative may be further reacted using various aldehydes yielding a library of hybrids that may have antimalarial, antitubercular, and cytotoxic effects.

Evaluation Of The Cytotoxic Profile Of Metformin And Y15 In Platinum Resistance Ovarian Cancer Cells, Keerthi Thallapureddy, Sam Batko, Zara Khan
Undergraduate Student Symposium
Metformin, an antidiabetic drug, has been previously shown to induce cytotoxicity in platinum resistant ovarian cancer cells and increase phosphorylation of Focal Adhesion Kinase (FAK), a tyrosine kinase implicated in the development of this platinum resistance. Therefore, we evaluated the combined cytotoxic efficacy of Metformin and the focal adhesion kinase inhibitor 1,2,4,5-Benzene Tetra amine tetra hydrochloride (Y15) in platinum resistant OVCAR 3 ovarian cancer cells. The cells were treated with concentrations of Y15 and Metformin to determine IC50 values, which were then used to treat cells with Y15 and Metformin separately and in combination. DNA fragmentation and poly ADP …

Molecular Chlorination Of Sucrose And Possible Growth Effects On Human Gut Microbiota, Kristi Njaravelil, Avidor Gerstenfeld
Undergraduate Student Symposium
Bacteria in our gut, are responsible for facilitating a variety of functions from metabolism to maintaining immunological homeostasis. The gut microbiota have also been shown to be affected by diet. Sucralose, a minimally metabolized, non-nutritive, and non-caloric sweetener, is found in a variety of food and drinks marketed to diabetics and health conscious individuals. Sucralose is chlorinated sucrose (common table sugar). Indicators suggest that sucralose may have a deleterious effect on gut microbiota, possibly leading to health conditions such as Crohn’s disease. Although there are likely several mechanisms involved, the purpose of this experiment is to focus on the effects …
Phycocyanin Enhances The Cytotoxic Profile Of Cisplatin In Platinum Resistant Ovarian Cancer Cells By A Mechanism That Is Focal Adhesion Kinase Dependent, Syed Hussain, Shona Joseph
Phycocyanin Enhances The Cytotoxic Profile Of Cisplatin In Platinum Resistant Ovarian Cancer Cells By A Mechanism That Is Focal Adhesion Kinase Dependent, Syed Hussain, Shona Joseph
Undergraduate Student Symposium
A major treatment approach in ovarian cancer is platinum based therapy. Initially more than 80% of cancer patients with advanced stage ovarian cancer achieve remission with platinum therapy. However, the majority of these patients relapse and develop drug-resistant disease over time. The overexpression of the tyrosine kinase, focal adhesion kinase (FAK) causes this resistance, which can promote cancer cell survival and metastasis. Prior experiments report that Phycocyanin (C-PC), an accessory pigment in the Cyanobacteria spirulina, demonstrates cytotoxicity towards multiple cancer cell lines and enhances cisplatin activity in lung cancer. This study evaluated the ability of C-PC to sensitize the …
Porphyrin Basicity Competition Studies Of Octa Alkyl Substituted Porphyrins With H2tpp, Alfredo Lam
Porphyrin Basicity Competition Studies Of Octa Alkyl Substituted Porphyrins With H2tpp, Alfredo Lam
Undergraduate Student Symposium
Competition studies of the free base octa alkyl substituted porphyrins for the protons were carried out using H2TPP. The reaction with H2OEP produces the free base H2OEP, the dication H4OEP+2, and the monocation H3OEP+1. Although the monocation is easily seen in the solution, it is difficult to isolate. The cause appears to be a type of disproportionation reaction taking place upon crystallization, where the dication is formed at the expense of the monocation. In each experiment, an equimolar solution of two free-bases was made. Since H …

Urbanization Effects On Size And Fecundity Of Nephila Clavipes, Jake Ripp
Urbanization Effects On Size And Fecundity Of Nephila Clavipes, Jake Ripp
Undergraduate Student Symposium
Typically, urbanization leads to habitat destruction and negative effects on the success of native species, however generalist predators like spiders may be exploiting these areas. Urban habitats tend to be warmer (due to the heat island effect), harbor an abundance of light attracted prey species and contain reduced densities of large native predators (bats and birds) when compared to natural areas. These attributes may provide Nephila clavipes, the Golden Orb Weaver, with an optimal habitat which enhances their overall productivity. I examined the effects of increasing levels of urbanization on body size and fecundity of N. clavipes. I …
Fighting Antibiotic Resistance By Encouraging Bacteria To Cheat, Uzair Mohammed, Tom Abraham, Khadija Chowdhury
Fighting Antibiotic Resistance By Encouraging Bacteria To Cheat, Uzair Mohammed, Tom Abraham, Khadija Chowdhury
Undergraduate Student Symposium
Antibiotic resistance in bacteria is a significant public health concern. Some bacteria degrade penicillinderived antibiotics by expressing the enzyme beta-lactamase. This provides protection for the entire colony, creating an incentive for other bacteria to “cheat” by benefiting from the enzyme without incurring the resource costs associated with producing it. It may seem that this free-rider problem would prevent cooperation from arising within an evolutionary framework, but many instances have been described in nature. Previous research has shown that the expected outcome is a coexistence between cooperators and cheaters, with the group becoming increasingly susceptible to eradication as the fraction of …

Science-Based Policy Plan For Australia's Coral Reefs, David Booth, Lauren Nadler, Steve Doo, Elizabeth Madin, Sue-Ann Watson
Marine & Environmental Sciences Faculty Reports
Australia’s coral reefs are currently under threat from a range of short-‐ and long-‐term stressors. The ability of corals to recover from acute disturbance events, such as bleaching, cyclones and crown-of-thorns seastars outbreaks, is greatly influenced by the multitude of stressors reefs are currently experiencing (1). Since healthy coral habitat is essential for the persistence of associated fish and invertebrate communities, as well as the industries that rely on them (2), all possible action must be taken to reduce stress factors to corals and associated organisms. Practical changes to current reef policies will reverse the decline in the health of …

HCNSO Student Theses and Dissertations
Ambient and recreational surface waters worldwide experience fecal pollution due to a variety of anthropogenic sources. Fecal waste has been proven, for over a century, to harbor pathogenic microorganisms which subsequently cause a variety of disease and illness in human hosts. The benefits of utilizing fecal indicator bacteria (FIB) as a simple, inexpensive means to detect fitful human pathogens within a variety of water matrices are vast. However, no universal agreement exists in regard to which indicator is best suited for detection of fecal contamination and pathogens in environmental waters, and no single standard for bacterial indicators has been federally …
Reflections On Peace From Interculturality, Dora Elvira Garcia-Gonzalez
Reflections On Peace From Interculturality, Dora Elvira Garcia-Gonzalez
Peace and Conflict Studies
This article purpose to think about interculturality in connection with what peace means, since many of the great conflicts in the history of humankind have been provoked by the failure to settle conflicts, by the absence of genuine dialogue and the inability to listen, thus producing violence among persons and among cultures. Therefore, to overcome these situations it is necessary a deep understanding of what peace means, as well as of its relation to justice and ethics. This will make it possible to seek the development of a positive interculturality, within a framework of peace. The existence of interculturality does …

An Endemic Commensal Leucothoid Discovered In The Tunicate Cnemidocarpa Bicornuta, From New Zealand (Crustacea, Amphipoda), Kaitlyn M. Brucker
HCNSO Student Theses and Dissertations
Precise descriptions and comprehensive taxonomies of species and their ecology are essential in monitoring changes in marine biodiversity at multiple spatial scales. A currently undescribed species of commensal amphipod in the genus Leucothoe is reported from New Zealand, collected from the endemic tunicate Cnemidocarpa bicornuta. This species differs from others in the genus in having a one-articulate first maxilla palp and an apically produced tuberculate lobe on the inner margin of the outer plate of the maxilliped. Previous taxonomic surveys in New Zealand waters did not document this species, indicating that it may be a recent arrival. This research …

Sponge Distribution And The Presence Of Photosymbionts In Moorea, French Polynesia, Christopher J. Freeman, Cole Easson
Marine & Environmental Sciences Faculty Articles
Photosymbionts play an important role in the ecology and evolution of diverse host species within the marine environment. Although sponge-photosymbiont interactions have been well described from geographically disparate sites worldwide, our understanding of these interactions from shallow water systems within French Polynesia is limited. We surveyed diverse habitats around the north coast of Moorea, French Polynesia and screened sponges for the presence of photosymbionts. Overall sponge abundance and diversity were low, with <1% cover and only eight putative species identified by 28S barcoding from surveys at 21 sites. Of these eight species, seven were found predominately in shaded or semi-cryptic habitats under overhangs or within caverns. Lendenfeldia chondrodeswas the only species that supported a high abundance of photosymbionts and was also the only species found in exposed, illuminated habitats. Interestingly, L. chondrodes was …1%>
Distribution, Abundance And Movement Of Fish Among Seagrass And Mangrove Habitats In Biscayne Bay, Patrick C. Goebel
Distribution, Abundance And Movement Of Fish Among Seagrass And Mangrove Habitats In Biscayne Bay, Patrick C. Goebel
HCNSO Student Theses and Dissertations
Inshore tropical and subtropical estuaries harbor a relatively high abundance and diversity of organisms. Specifically within estuaries, mangrove and seagrass habitats provide shelter and food for a plethora of organisms, through some or all their life histories. Given the biological connection between offshore coral reefs and coastal estuaries, there is a critical need to understand the underlying processes that determine distribution and abundance patterns within mangrove-seagrass habitats. The predatory fish assemblage within the mangrove and seagrass beds of Biscayne Bay, Florida (USA), was examined over 24-hr. time periods along a distance and habitat gradient from the mangrove edge and nearshore …
Powering The Planet: The Role Chemistry Plays In Solar Energy Technology, Amy M. Scott
Powering The Planet: The Role Chemistry Plays In Solar Energy Technology, Amy M. Scott
Climate Sustainability Lecture Series
Global energy demands are projected to double by 2050, according to the U.S. Department of Energy, and solar energy has the greatest potential as the most benign, universal resource for generating electricity. However, harnessing the solar energy efficiently and converting it towards useful forms of power that are compatible with our current infrastructure remains an elusive goal. Today’s solar energy utilization relies on silicon-based photovoltaic (PV) technology, which converts photon energy to electrical energy. The efficiency of these devices remains low (< 30%) and the cost of processing silicon and installing solar panels in homes makes PV uneconomical compared to the current price of electricity. Research efforts towards developing new inorganic and organic materials for thin film PV to replace silicon are currently underway. Organic materials are particularly interesting from the standpoint of developing simple, cheap materials that can be easily tailored for future PV devices. The future of solar energy utilization relies on developing solar paints for vehicles, solar shingles for rooftops, and spray-on solar ink for small device applications, but continued fundamental research is needed for decreasing cost and improving efficiency for next generation devices.
Periodicity In Quantum Calculus, Jeffrey T. Neugebauer
Periodicity In Quantum Calculus, Jeffrey T. Neugebauer
Mathematics Colloquium Series
After a brief introduction to time scales, we will explore periodic functions on time scales. We will discuss how periodicity is defined on time scales that are not periodic. In particular, we will look at periodicity in the quantum case. Two definitions of periodicity have recently been introduced. One definition is based on the equality of areas lying below the graph of the function at each period; the other regards a periodic function to be one that repeats its values after a certain number of steps. We will show a relation between these two definitions and then use this relation …
