Investigating The Bouba-Kiki Phenomenon In Impression Formation, Pritika Shah
Investigating The Bouba-Kiki Phenomenon In Impression Formation, Pritika Shah
Undergraduate Student Symposium
Humans associate sounds and symbols in non-arbitrary ways. One example of this phenomenon is the Bouba/Kiki effect: the nonword “Bouba” is associated with rounder shapes, whereas “Kiki” is associated with sharper shapes. Although many studies have been done on the Bouba-Kiki effect, it has not been studied in the context of personality judgments and impression formation. Study 1 used a between-subjects design to test the Bouba/Kiki effect in this domain. A person named “Bouba” was rated as more moral than a person named “Kiki”, whereas “Kiki” was rated as more sociable, however no significant difference was found for competence ratings. …
The Effects Of Herbal Products In Cartilage Healing And Reducing The Progression Of Osteoarthritis, Mariya Baig
The Effects Of Herbal Products In Cartilage Healing And Reducing The Progression Of Osteoarthritis, Mariya Baig
Undergraduate Student Symposium
Treatment for osteoarthritis (OA) is primarily aimed at symptom management and is generally limited with emphasis placed on therapy and drugs such as NSAIDs, opioids, and acetaminophen. However, these drugs pose health risks for long-term use including contraindications, gastrointestinal, and cardiovascular issues. Thus, this systematic review of literature was conducted to evaluate the impact of the herbal products, turmeric and ginger, on reducing the progression of OA when utilized on both a short-term and long-term basis. After evaluating the content of several scholarly journals, it was found that turmeric and ginger can aid in symptom management of OA and promote …
Understanding The Origin Of Mutations Using Ab Initio Molecular Dynamics, Supratik Pasupuleti, Anthony Bianco
Understanding The Origin Of Mutations Using Ab Initio Molecular Dynamics, Supratik Pasupuleti, Anthony Bianco
Undergraduate Student Symposium
Proton transfer within DNA base pairs is a possible origin for mutations which can ultimately lead to cancer. To better understand this potential source of mutations we have modeled this process using Ab Initio molecular dynamics simulations of model systems for DNA base pairs in water. These simulations have provided insight into how often and when proton transfer occurs in these systems while also highlighting the relationship between the likelihood of a proton transfer event and the way the water molecules are coordinated around the model system for DNA. This in turn has allowed for a greater understanding of potential …

Who Stressed The Dogs Out: A Case For Studying Mitochondrial Dna As A Novel Biomarker For Stress In Canines, Aidan Kunju, Ariana Ali, Ritika Kothur, Olivia Singleton
Undergraduate Student Symposium
Canines transiting through animal shelters experience extreme stress that is subsequently ameliorated by adoption into loving (human) homes. These transitions provide exceptional opportunities to study links between social stress and physiological processes, and to develop biomarkers for stress and social bonding with applications in both animal welfare and human health. Here, we propose a novel approach to the study of shelter-related stress in dogs, and of stress reversals following adoption. Specifically, we will quantify mtDNA dynamics in buccal swabs sampled during shelter intakes of canines at the Broward County animal shelter, as well as samples collected after these animals’ adoptions …
Touch Sensitivity In College-Aged Adults, Hannah Laufenberg, Isabel De Angelis
Touch Sensitivity In College-Aged Adults, Hannah Laufenberg, Isabel De Angelis
Undergraduate Student Symposium
The present study aims to identify what factors influence pain perception. Previous studies have focused on the differences in pain tolerance between genders, but this difference could be due to differences in physiology. The COMT rs4680 single nucleotide polymorphism (SNP) has been implicated in stress and pain perception (Serrano et al., 2019, Hill et al., 2018). G/G/ allele carriers perform better under stressful conditions and perceive less pain relative to the A/- allele carriers. Here we examined how gender, body size, and genetic makeup influences pain intensity, pain threshold, and pain tolerance. Participants will be asked to passively drool into …
Skill Position Football Players Have Greater Vertical Jump Kinetic Asymmetry But Better Performance Than Big Skill And Big Position Players, Ashley Mcdonough, Ayoub Ziani
Skill Position Football Players Have Greater Vertical Jump Kinetic Asymmetry But Better Performance Than Big Skill And Big Position Players, Ashley Mcdonough, Ayoub Ziani
Undergraduate Student Symposium
The vertical jump (VJ) assesses lower limb power and is tested in players entering the National Football League’s (NFL) draft. Limb asymmetry of ≥10% has been linked to injury and poor performance. Assessing VJ performance and kinetic asymmetry by player position may guide group-based training programs. We sought to determine if VJ performance and kinetic asymmetries were different between football position groups, Skill Players (SP), Big Skill Players (BS), and Big Players (BP). Sixty participants (age, 22.7 1.1yrs;± ht, 186.4±6.8cm; mass, 103.6±21.2kg) training for the NFL draft performed VJ on dual uniaxial force plates. Performance variables of reactive strength (RSI-mod) …
Synthesis Of Chelating Polymers Via Raft For Metal Extraction, Agustin Olivares, Blake Naar
Synthesis Of Chelating Polymers Via Raft For Metal Extraction, Agustin Olivares, Blake Naar
Undergraduate Student Symposium
Heavy metal contamination in drinking water is known to cause damage to multiple organs and is one of the major causes of cancer. The presence of heavy metals in water has the ability to cause lifethreatening conditions. The purpose of our study is to synthesize metal binding polymers and to determine their efficiency at extracting heavy metals from contaminated water. Poly pentafluorophenyl acrylate (PPFPA) was synthesized via the employment of reversible addition-fragmentation chain transfer (RAFT) polymerization using pentafluorophenyl acrylate (PFPA) as the monomer to create linear and hyperbranched polymers. RAFT polymerization allows control over molecular weight and the molecular architecture …

Unlearning Your Colonial Course Description To Transform Your Learning Culture, Zen Parry
Experiential Learning & Teaching in Higher Education
Education has undergone multiple transformations with preset syllabi and modes of presentation to learners. Within the learning models utilized today, critical discussions on issues in higher education, social, economic, environmental, and racial justice settings have become important and at times, media headlines. Reading through course descriptions in an academic catalog or brochure will inform you about what the curriculum offers and what it does not. The course description wording brings into question two issues: whether the language used affects the understandability and relatability of the content by students of the course or, the course description represents the perspective of the …

Comparative Toxicity Of Hydrocarbons For Evaluation Of Lysmata Boggessi As An Experimental Proxy For Deep-Water Column Micronekton, Dorothy-Ellen A. Renegar, Nicholas Turner, Gopal Bera, Eileen G. Whitemiller, Bernhard Riegl, Jose Sericano, Anthony H. Knap
Marine & Environmental Sciences Faculty Articles
The potential impacts of sub-surface hydrocarbon plumes to deep-water column micronekton are an important consideration in a more complete understanding of ecosystem effects resulting from deep-sea oil spills. However, evaluating toxicity in these organisms presents multiple challenges, and the use of a shallow-water proxy species allows comparison and validation of experimental results. This study thus examined the suitability of the peppermint shrimp, Lysmata boggessi, as an experimental proxy for ecologically important deep-sea zooplankton/micronekton in hydrocarbon toxicity assays. This crustacean species occurs in shallow coastal marine environments throughout the western Atlantic, Caribbean and Gulf of Mexico, is similar in …
How Prey Defense Patterns Predator-Prey Distributions, Evan Haskell
How Prey Defense Patterns Predator-Prey Distributions, Evan Haskell
Mathematics Colloquium Series
In ecology, predator and prey species share a common interest in survival. However, this common interest places these species at odds with each other. Predators need to consume prey for their survival. Prey, on the other hand, do not survive if they are consumed. To meet their needs, predators engage in foraging or prey-taxis behaviors whereby they seek areas of high prey density. For prey there are numerous defense strategies to engage including aposematic mechanisms to advertise they are not worth the predator’s while, attacking the predator through chemical or community defense mechanisms, and alarm calls to seek assistance from …
Comparison Of Recent Survey Techniques For Estimating Benthic Cover On Caribbean Mesophotic Reefs, Joseph R. Pawlik, Roy A. Armstrong, Stephanie Farrington, John Reed, Sara Rivero-Calle, Hanumant Singh, Brian K. Walker, Jason White
Comparison Of Recent Survey Techniques For Estimating Benthic Cover On Caribbean Mesophotic Reefs, Joseph R. Pawlik, Roy A. Armstrong, Stephanie Farrington, John Reed, Sara Rivero-Calle, Hanumant Singh, Brian K. Walker, Jason White
Marine & Environmental Sciences Faculty Articles
Highly divergent estimates of benthic cover of sponges have been reported for Caribbean mesophotic reefs (90-100 m) based on quadrat point-intercept data collection using 2 methods: visual surveys conducted in situ by technical divers, and analyses of photographs taken by unmanned underwater vehicles (UUVs). The second method has been criticized for potential errors from image distortion caused by variable camera angle relative to the substratum, but without a broader comparison of both methods. We find that studies that have used the UUV-based method are advantageous for a number of reasons, most importantly: (1) access to the full mesophotic zone, (2) …

Chemistry and Physics Faculty Proceedings, Presentations, Speeches, Lectures
The protonation of meso-Tetra(2,3,4-trifluoromethylphenyl) porphyrin (TF) and meso-Tetra(pentafluorophenyl) porphyrin (PF) will be studied through UV vis spectroscopy. Protonation is achieved by titration of each porphyrin in toluene with trifluoroacetic acid (TFA). The presence of a wavelength shift from the free base Soret to the protonated Soret will indicate the formation of a dication. The data from the UV spectra will be used to calculate the pKa values associated with each porphyrin. Based on the results, the average pKa for TF upon protonation was 2.07, while the average pKa for PF was 1.36 over four trials. A greater acidic value for …

Biology Faculty Articles
The pivot to remote and hybrid learning during the Covid-19 pandemic presented a challenge for many in academia. Most institutions were not prepared to support this rapid change, and instructors were left with the burden of converting a traditional face-to-face course into multiple modalities with very limited preparation time. When institutional support is lacking, we posit that instructor communities of practice can help provide the resources needed to meet the instructional demands. Tiny Earth, a course-based-undergraduate research experience (CURE) and international network of instructors and students, responded to the instructional challenges of the pandemic by leveraging its large community of …

Analysis Of The Magnetic Signature Of Surface Waves Measured In A Laboratory Experiment, John Kluge, Alex Soloviev, Cayla W. Dean, Geoffrey K. Morrison, Brian K. Haus
Marine & Environmental Sciences Faculty Articles
A magnetic signature is created by secondary magnetic field fluctuations caused by the phenomenon of seawater moving in Earth’s magnetic field. A laboratory experiment was conducted at the SUrge STructure Atmosphere INteraction (SUSTAIN) facility to measure the magnetic signature of surface waves using a differential method: a pair of magnetometers, separated horizontally by one-half wavelength, were placed at several locations on the outer tank walls. This technique significantly reduced the extraneous magnetic distortions that were detected simultaneously by both sensors and additionally doubled the magnetic signal of surface waves. Accelerometer measurements and local gradients were used to identify magnetic noise …

Critical-Thinking Experiences Of Chinese And U.S. College Students: A Comparative Analysis Using Phenomenology, Lu (Wendy) Yan
Critical-Thinking Experiences Of Chinese And U.S. College Students: A Comparative Analysis Using Phenomenology, Lu (Wendy) Yan
The Qualitative Report
In this study, I investigated the critical-thinking experiences of seven Chinese international and five U.S. students attending a large public university in the United States. I conducted a comparative analysis of these groups’ different experiences with critical thinking in this context, while closely following the twin methods of epoché and reduction in phenomenology to remain attuned to any personal biases. My results indicated that Chinese and U.S. students experienced critical thinking differently on the basis of the four universal existentials noted by van Manen (2016): lived experiences of relation (self–other), materiality (things), time, and space/place. Specifically, the Chinese students tended …

Numerical Schemes For Integro-Differential Equations Related To Alpha-Stable Processes, Xiaofan Li
Numerical Schemes For Integro-Differential Equations Related To Alpha-Stable Processes, Xiaofan Li
Mathematics Colloquium Series
The mean first exit time, escape probability and transitional probability densities are utilized to quantify dynamical behaviors of stochastic differential equations with non-Gaussian, α-stable type Lévy motions. Taking advantage of the Toeplitz matrix structure of the time-space discretization, a fast and accurate numerical algorithm is proposed to simulate the nonlocal Fokker-Planck equations on either a bounded or infinite domain. Under a specified condition, the scheme is shown to satisfy a discrete maximum principle and to be convergent. The numerical results for two prototypical stochastic systems, the Ornstein-Uhlenbeck system and the double-well system are shown.
Secondary School El Teachers’ Classroom Language Proficiency: A Case Study In Bangladesh, Md. Abdur Rouf, Abdul Rashid Mohamed
Secondary School El Teachers’ Classroom Language Proficiency: A Case Study In Bangladesh, Md. Abdur Rouf, Abdul Rashid Mohamed
The Qualitative Report
The study reported here aimed to examine the classroom language proficiency (CLP) of secondary school (SS) English language (EL) teachers in Bangladesh. It is obvious that the EL teachers in a non-native English-speaking context like Bangladesh need to have a very good oral proficiency in the target language (TL) as part of their content knowledge so that learners can take them as models and classroom teaching-learning is effective. Following a multiple case study approach, data were collected from six SS EL teachers as primary informants and four head teachers (HTs), three teacher trainers (TTs), and one curriculum expert (CE) as …
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Spatial And Temporal Patterns Of Fire On Saipan, Cnmi, Ilan E. Bubb, Zachary B. Williams
Marine & Environmental Sciences Faculty Articles
Sediment core studies from Saipan suggest that fires did not play a prominent role in the disturbance regime of the Mariana Islands and have increased in frequency since human settlement around 4,000 years ago. On Saipan fires are understood to interrupt the pattern of succession leading to the degradation of native limestone forests, the proliferation of grasslands and the eventual creation of badlands. Little baseline data regarding the spatial and temporal patterns of fire on Saipan exist to create effective Fire Management Plans. This project uses Landsat 8 images from April 2013 to July 2020 and the Normalized Burn Ratio …
