Synthesis of a Sterically Hindered Three-Coordinate Pd(II) Complex for C–F Reductive Elimination Sojung Kim The use of a Pd(II)/Pd(0) redox couple in catalytic fluorination remains elusive, yet is desirable for selective formation of C-F bonds. We hypothesized that the ligand tri(1-adamantyl)phosphine may promote C-F reductive elimination from LPdIIAr(F) complexes by disfavoring dimerization to stabilized four-coordinate states. Density functional theory calculations suggested sterically hindered and electron deficient ligands could promote C-F reductive elimination, but synthesis of Pd-F species for experimental validation was precluded by competing decomposition under the tested conditions.

Synthesis, Characterization and Molecular Targeting of Quinoline Antimicrobials Anna Pauline Brogan

The prevalence of antibiotic resistant pathogens has become a crisis in the clinical setting. For new antibiotics to be developed, compounds with novel bacterial targets must be discovered. Here, it is demonstrated that the quinoline class of compounds has antibiotic activity by targeting the trans-translation pathway. It is shown that the compounds target a protease of clinical interest. Research into these compounds could lead to a new drug to aid in the fight against superbugs.

Tank to Capture the Physics of Ctenophore cilia with laser imaging Carlos Abarca Ctenophores are the largest animals in the world who rely primarily on cilia to swim. The goal of this project is to capture motion of these cilia using high speed laser based imaging. In order to do this, the ctenophores will be placed in a mean flow swim tunnel and held stationary by custom-built grippers as they swim against the flow. The results will allow us to understand the physics behind cilia at large scales. Margaret Byron 163 Alumni Hall, HUB-Robeson Center
Targeting trans-translation in pathogenic bacteria with natural products Tatiana Mcanulty Bacteria continuously develop resistance to conventionally-prescribed antibiotics; thus, the need for new antibacterial agents is pressing. Natural products from Hawaiian marine plants were tested for activity against Mycobacterium tuberculosis, Methicillin-resistant Staphylococcus aureus, and Bacillus anthracis in a novel approach to target the trans-translation pathway. The performed screens identified natural products able to inhibit growth and kill pathogenic bacterial cells, introducing a prospective source of new drugs to combat the threat of growing resistance to antibiotics.

Teaching Interventions to Enhance Knowledge on Palliative Care Referrals: What the Evidence Shows Kalei Kowalchik Palliative care (PC) utilizes a collaborative healthcare team to provide holistic care to persons, while managing their symptoms and alleviating suffering associated with their illness(s). Unfortunately, this service is underutilized and research shows that nurses have a limited understanding of PC which inhibits persons from receiving appropriate referrals to PC. Therefore, a literature review was conducted and showed that a nurse led teaching intervention increased nurses understanding of PC. Michael Evans 102 Alumni Hall, HUB-Robeson Center
Temporal and Geographical Structure of Dengue Virus Variants Alicia Danelle Kriner and Morgan Namie

Dengue, a single-segment positive-stranded RNA Flaviviridae virus, is a mosquito-borne virus that exists in tropical and subtropical regions of the world. Four serotypes of dengue co-circulate globally, allowing dengue to undergo frequency-dependent selection in addition to other types of viral evolution. Phylogeny of the four serotypes within Asia and the Americas were evaluated and compared. Associations were analyzed to identify migratory links and epidemics in order to better understand the evolution of Dengue.

The Accuracy and Effectiveness of Low-cost Indoor Air Quality Sensors Stephen Waskiw Many low-cost particulate matter sensors are being sold for people to measure their indoor air quality. These sensors can be beneficial to making sure our air is clean and healthy. Unfortunately, there is no standard in place to compare how accurate they are. I am researching different sensors by exposing them to particulate and measuring how they perform compared to a high-end, accurate sensor. These tests will help reveal the proficiencies of low cost sensors. Donghyun Rim 225 Alumni Hall, HUB-Robeson Center

Average CFU/mL, luminescence levels in presence of autoinducer, motility, ability to conjugate, and luminescence levels from a squid single-strain colonization will be demonstrated. In addition, differences in the luxIR region of the bacterial genome between MRE002 and the positive control ES114 will be highlighted. Tim Miyashiro 295 Alumni Hall, HUB-Robeson Center
The Dual Nature of the Student-Athlete Identity: How Being Both a Student and Athlete Impacts an Individual’s Self-Concept Peyton Loomis Previous research focused on student-athletes, however, there is a gap in the data looking specifically at student-athletes from an identity theory perspective. This research aims to obtain a better understanding the role both identities play for an individual. A survey instrument was used to measure the identities of the student athletes from a large Northeastern University. Data will be analyzed to explore how both identities impact self-perception, academic involvement, time-management, group identities, and overall well-being.

The effect of adolescent social stress and genetic background on morphine consumption in C57BL/6J and BALB/cJ mice. Grant Swisher There is a rising concern of opioid misuse in the United States. Studying the genetic and environmental contributions to opioid consumption in rodents can help understand the factors that contribute to risk of abuse. This study investigated whether social stress during adolescence would affect voluntary morphine consumption during adulthood in two different mouse strains. Our results revealed significant concentration by strain interactions; however, there was no main effect of social stress on morphine consumption. Helen Kamens 342 Heritage Hall, HUB-Robeson Center
The Effect of Economic Sanctions on Respect for Human Rights Katherine Bartuska How do sanctions affect respect for human rights? I hypothesize that both the threat and implementation of economic sanctions will decrease the government's respect for human rights, which stems from two scenarios: either the citizens engage in antigovernment behavior or the elites initiate a coup. I analyze all countries that have been the target of sanctions from 1970-2005. A time-series cross national analysis and mediation analysis are utilized to test my hypotheses.

The Effect of Faka/FakB Deletions on Lipoprotein production in S.aureus Sheherbano Hussain Antibiotic resistance is a growing problem in global health, as opportunistic pathogens are causing fatal infections that are unable to be treated. Fatty acid kinase A and B are involved in lipid metabolism and the synthesis of membrane phospholipids in gram positive bacterial pathogens like Staphylococcus aureus. Determining the effects of FakA and/or FakB deletions can prove critical to understanding the dynamics of the bacterial cell envelope and developing new techniques to counter antibiotic resistance.

The effect of reducing cell wall feruloyation by constitutive apoplast targeted expression of ferulic acid esterase on maize internode expansion Marissa Kowalski

In grass cell walls, ferulic acid is esterified to arabinoxylan residues forming dimers via the oxidative coupling reactions, cross-linking arabinoxylan chains. Ferulate cross-linking is suggested to play a role in different plant processes. In the current study we investigated the role of cell wall feruloylation in internode expansion in maize using transgenic plants, which levels of cell wall ferulates have been reduced by targeted expression of Aspergillus niger ferulic acid esterase A to the apoplast

THE EFFECT OF SUBUNIT DELETIONS ON SAGA COMPLEX BINDING IN SACHAROMYCES CEREVISIAE Matthew F Driban

The SAGA complex is a multi-functional protein complex involved in transcriptional regulation and histone modification, particularly under stress. Notably the SAGA complex has been linked to development of certain neurodegenerative diseases and cancers. To better characterize SAGA's ability to regulate gene expression under various stressors, I analyzed SAGA's binding characteristics under two conditions: subunit knockouts and heat shock. These analyses resulted in a clearer picture of SAGA's regulatory role under different conditions of stress.

The effects of proximity to active hydrocarbon seeps on the abundance and diversity of fauna associated with deep water octocorals. Orli Glickman To examine effects of natural hydrocarbon seepage on health of deep-water octocorals, we have examined the effects of proximity to seepage on the abundance and diversity of 13 morphospecies associated with the octocoral Callogorgia delta. Our preliminary analysis indicates that the abundance of catshark eggs is higher and ophiuroids is lower on non-seep compared to seep C. delta. Data was compared to Paramurecia sp. B3 and showed greater occurrence of other associates than C. delta. Charles Fisher 142 Alumni Hall, HUB-Robeson Center
The Effects of School Stress on Student-Athlete GPA and Sport Enjoyment Emily Blaker

The current study investigated college stress between USCAA student-athletes and non-athletes, and its relationship to academic performance, and to a student-athlete's enjoyment of their sport. Athletes were less stressed than non-athletes, and had a lower mean GPA. The athletes who scored higher on stress also scored lower on sport enjoyment. Regression analyses found that sport enjoyment and academic engagement do not have any influence in moderating the relationship between stress and GPA.

The environmental and physiological effects of caffeinated compost on green beans (Phaseolus vulgaris) Ian David Chamberlain

Caffeine is a common application in compost. How does its presence interact in the garden? Will an exogenous application of caffeinated compost impact plant growth and development, and will caffeine uptake occur? Between caffeine and control treatments of compost, my research shows there is little difference in the growth and morphology of green beans. However, as a toxic alkaloid, caffeine in composts may still yet provide a twofold effect on pest control (compost and plant).

The impact of Qrr1 expression on Vibrio fischeri Shyan Cousins Qrr1 is a small RNA found in Vibrio fischeri that regulates traits such as motility, luminescence, and host colonization. LuxO, the s54 -dependent response regulator, is known to activate the transcription of qrr1. It;s believed that there are other regulators of Qrr1. To investigate these other factors and determine to what extent Qrr1 expression influences motility, spotting and motility assays were performed. These assays allow for the quantification of Qrr1 expression and motility rates. Timothy Miyashiro 269 Alumni Hall, HUB-Robeson Center
The Impact of Social Support and Adverse Childhood Experience on Alcohol Use and Psychological Distress in College Students Amanda Moore This study examined the relationship between adverse childhood events (ACEs) and social support on drinking behaviors and psychological distress in undergraduate students. From prior research (Strine, 2012) we predicted that ACEs would be related to higher levels of drinking and psychological distress, while social support would find the opposite. A preliminary multiple regression analysis suggests a significant negative relationship between social support and psychological distress F(2, 16) = 4.86, p = .024, R2 = .38.

The impact of sypG on qrr1 activation in vibrio fischeri Roxanne Evande Luminescence production is regulated by the small regulatory RNA qrr1. The goal of this study is to understand to what extent does SypG impact Qrr1-regulated phenotypes. Two different experiments will aid in answering the overall question. The impact of qrr1 expression on luminescence and the impact of sypG on Qrr1-regulated luminescence will be observed using qrr1 mutants. The results will aid in understanding the physiological impact of SypG regulation of qrr1. Tim Miyashiro 230 Alumni Hall, HUB-Robeson Center
The Impact of Temperature on Bacterial Type VI Secretion in the Squid-Vibrio Symbiosis Amanda Williams Host organisms contain complex microbial populations that serve critical functions. A type VI secretion system (T6SS) is a contact-dependent killing apparatus that bacterial cells can employ against each other. In host organisms, the amount and efficacy of T6SS-mediated killing can affect the host's microbial composition. Little is known, however, about the extent to which environmental factors such as temperature may impact killing, and therefore how they ultimately impact the structure of microbial communities within hosts.

The Impacts of Mites on Brazilian Apiculture Nicole R Guise et al

Bees play an important role in Brazilian agriculture. Brazil is the world's ninth largest honey producer, turning a profit of $82 million (Santos, Otesbelgue, & Blochtein, 2018). According to FAOSTAT, Brazil's beehive production has remained steady over the last five years; though it has not yet recovered to peak production. One challenge beekeepers face is protecting their hives from mites. Mites are a vector for viruses that cause bee hive collapse (Brettell & Martin, 2017).

The Influence of Physical Activity, Diet, and Substance Use on Academic Performance Peter Matthews The aim of this research was to examine the relationship between college student's physical activity, diet, and substance use and academic performance. Data was collected from college students concerning demographics, physical activity, fruit and vegetable consumption, and substance use, as well as cumulative GPA. Analyses revealed that GPA was lower among those who were less physically active, displayed unhealthy eating habits, and used substances thus highlighting the link between health behaviors and academic performance Melissa Bopp 308 Heritage Hall, HUB-Robeson Center
The Influence of Self-Resembling Cues in the Cross-Race Memory Effect Mia Elizabeth Caputo

Current memory theory suggests that people should have better memory for faces that look dissimilar from the average face that is encountered in daily life. However, people have better memory for same-race faces and interaction with other-race faces only minutely reduces this effect. This research aims to understand the contention between these two theories and we hypothesize that this lies with the similarity of faces --not to the average face-- but to one's own image

The Pros and Cons of Perceived HIV-Related Stigma in Younger and Older Adolescents in Botswana Karina Grullon Perez

Adolescents living with HIV may experience stigma (i.e. be subject to discrimination), anticipate stigma (i.e. change thoughts or behaviors to avoid discrimination), and internalize stigma (i.e. think less of themselves because of their HIV serostatus). We hypothesized that adolescents' self-reports of stigma are associated with treatment outcomes. Contrary to our expectation, there was no association between stigma and virologic treatment outcomes among HIV-infected adolescents on antiretroviral therapy when considering the entire adolescent age spectrum.

The Relation Between Perceived and Population Based Environmental Risk and Maternal Stress Centia Thomas

This current study attempts to identify which environmental risk factors affect maternal stress, and how the difference between perceived and population-based environment risk factors are related to participant's indications of maternal stress. The results of this study suggest that mothers with higher socioeconomic statuses are more likely to present more indicators of maternal stress, and that perceived environmental risk does not have a statistical significance on the severity of maternal stress reported.

The School to Prison Pipeline and Access to Higher Education Tatiana M Klett

The key areas that activists tend to focus on in the School to Prison Pipeline are the use of officers in schools, disciplinary policies, racial biases, and a high student-to-teacher ratio. I am focusing on the impact that the School to Prison Pipeline has on career planning and college readiness. Research shows that this is rarely an area that is focused on when addressing the School to Prison Pipeline.

The Social Networks of Mental Illness Related Cyberbullying on Twitter Ying Cheng Despite the significant development in psychiatry, stigma remains one of the biggest barriers preventing mentally-ill people from seeking help. Cyberbullying, a form of harassment using electronic means, affects people worldwide. This project investigates the manifestation of stigma through cyberbullying on Twitter. We found that mental-illness related words are frequently used to insult others. Such Environment with toxic messages belittles the pain mentally-ill people experience and perpetuates the stigma associated with mental diseases. Diane Felmlee 317 Heritage Hall, HUB-Robeson Center
THE STRUCTURAL CHANGE IN SUB-SAHARAN AFRICAN COUNTRIES Zhiyi He Following Diao, Harttgen, and Mcmillan (2017), we replicate the statistical analysis and extend it by adding recent data from the World Bank. We show that the decline in the employment share in agriculture continues. This decline is most pronounced for rural females. We also show that although the trend of the employment share follows the pattern observed in the rest of the world, its value-added differs. This difference suggests premature deindustrialization of high-income African countries. Aleksandra Slavkovic 204 Alumni Hall, HUB-Robeson Center

The α3β4 nicotinic acetylcholine receptor antagonist 18-Methoxycoronaridine decreases binge-like ethanol consumption in adult C57BL/6J mice Colton Ruggery The prevalence of alcohol use disorders (AUD) is a major health issue in the US, and unfortunately available therapeutics are ineffective and/or have unwanted side-effects. A new drug, 18-Methoxycoronaridine (18-MC), is an a3v4 nicotinic acetylcholine receptor (nAChR) antagonist that shows potential for reducing alcohol intake. This study further investigated 18-MC's actions on alcohol-related behaviors and consumption. Our results highlight the involvement of a3v4 nAChRs in alcohol consumption, while 18-MC had little effect on alcohol-related behaviors. Helen Kamens 257 Alumni Hall, HUB-Robeson Center
Traffic Delay Optimization Ikeoluwa Ogunranti The amount of time people spend at a traffic light differs. This time is known as traffic delay. Some motorists spend more time than others at a traffic light and this makes their travel time longer than expected. Using a traffic simulator makes it easier to monitor the free movement of cars by setting a fixed-time signal for the traffic light in order to measure the time each vehicle spends at the light.

TRIM 9 Acts as a Microtubule Check Point by Positively Regulating Exit into Axons Emily Yanoshak In neurons, microtubule polarity enables differentiation between axons and dendrites and promotes proper cell function. There are several known mechanisms that regulate polarity in dendrites, yet mechanisms at the cell body and their contribution to the cell's overall polarity are not fully understood. TRIM 9 proves to be a positive regulator of plus-end out neuronal processes, promoting the hypothesis of a relationship between the regulation and establishment of microtubule polarity at cell body exit points.

Understanding the Role of BOLA2 in Iron Transport Emma Stephanie Gogarnoiu

Although iron regulation and transport are well studied, the mechanisms of iron delivery from the transporter to iron-requiring enzymes remains poorly understood. BOLA2 is hypothesized to be an iron-transporting protein within human cells. To provide insight into potential metal-binding interactions, BOLA2 was purified and spectrophotometric titrations of the protein were performed using cobalt(II) as a surrogate for iron(II). The titrations indicate that BOLA2 binds cobalt(II) and motivate further studies of iron(II) binding to the protein.
