    An Analysis of the UK and US on the Perceived Adequacy of Workplace Mental Health Programs

    Julia Woods, Depts. of Business and Psychology, with Dr Deborah DiazGranados, VCU School of Medicine

    Research examining employee provided health benefits typically concentrate on evaluating a program’s impact on organizational outcomes such as retention, absenteeism, presenteeism, and cost-effectiveness (Cuffel, Goldman, and Schlesinger, 1999; Munz & Kohler, 1997). The typical methods used for evaluation of these programs tend to be quantitative in nature, however, qualitative methods could help organizations better understand how its employees react to and view such programs. This paper explores employee’s perceptions of health benefits provided by employers, specifically mental health programs, within the United Kingdom and the United States. These countries were chosen because of perceived similarities in culture, labor markets, views of the parity of mental and physical health care, and focus on individual's rights. A review and analysis of major categories of mental health programs were conducted to best capture the cultural context, effectiveness, and employee perception of employee health benefits. The search for literature primarily included online searches of the following databases (e.g., Google Scholar, PsychINFO, PubMed, PsycNET) for literature published between 1995 and 2019. The following key terms were used in different combinations: Mental health programs, mental health benefits, adequacy, employer-provided programs, employee satisfaction, employee perception, either the United Kingdom or the United States. In addition, to highlight a few common employer-provided mental health benefits a targeted search was done for specific benefits (e.g., employee assistance programs, workplace counseling, cognitive behavior therapy, mental health insurance/coverage, and stress management interventions) in combination with the previously listed terms. The initial search resulted in eight publications that were then used for a manual secondary search of reference lists which resulted in three additional publications that were used for the review. Results of the analysis of sources indicate that employer-provided benefits improved employee’s mental well-being, which in turn impacted their work. Interestingly, one study conducted by Elliot and Williams (2002) reported comments like “I haven’t had any panic attacks since counseling ended,” and “my workload is now being dealt with more quickly” by counseling clients. Qualitative reports such as these are particularly interesting when trying to understand how employees view their work after they conclude a mental health program. Future research should consider examining questions such as: 1) what is the overall and longitudinal impact on employee well-being from employer-provided mental health benefits, 2) how do employer-provided mental health programs influence personal well-being, and how does an employee’s personal well-being in turn influence employee productivity, and 3) how do cultural differences and a country’s approach to mental health care inform the employee’s availability/accessibility to mental health care at work.

    Effect of Political Ideology, Femininity, and Gender on Abortion Stigma

    Abortion stigma is a negative characteristic attributed to individuals who terminate a pregnancy that marks them as inferior to social ideals of womanhood (Kumar et al, 2009). One factor influencing abortion stigma is political ideology. Conservative individuals display more opposition to abortion and hold more abortion stigmatizing attitudes, when compared to their liberal counterparts (Bessett et al, 2015). Further, individuals’ gender may impact endorsement of these stigmatizing attitudes towards individuals who have had an abortion. Women have less stigma likely due to the fact that they could need to have an abortion (Patev, Hood, & Hall, 2019). Although gender seems to predict abortion stigma, it is unclear how individuals’ endorsement of traditional feminine characteristics may relate to abortion stigma, independent of gender. Abortion violates fundamental entities of womanhood, such as being a nurturing mother and being sexually pure (Kumar et al, 2009). Feminine ideals indicate that women should not have control over their own reproduction and sexuality, leading to increased stigmatizing attitudes towards women who have an abortion (Norris et al, 2011). Therefore, the endorsement of traditional feminine ideals may lead to increased abortion stigma, regardless of political ideology or gender. Limited study has examined the relationship between feminine characteristics and abortion stigma. Better understanding abortion stigma is essential; as, research has shown that stigmatizing attitudes can greatly affect the health of individuals who have had an abortion (Major & Gramzow, 1999; O’Donnell et al., 2018). The current study sought to determine the effect of femininity on abortion stigmatizing attitudes, beyond the effects of political ideology and gender. We initially projected that individuals with more traditional feminine values would hold more abortion stigma.

    Participants (N= 305) were recruited via Amazon Mechanical Turk and completed an online survey. The survey included the Stigmatizing Attitudes, Beliefs, and Actions Scale (Shellenberg et al., 2014) to assess abortion stigma, the Personal Attributes Questionnaire (Spence et al., 1974) to assess femininity, one item assessing gender (i.e., men coded as 1 and women coded as 2), and one item assessing political ideology (e.g., lower scores indicate conservative ideology). A hierarchical regression was conducted to determine how individuals’ femininity impacts abortion stigma, beyond the effects of gender and political ideology. Political ideology was entered in the first step, and was significant,b= -.54, SE= .28, p< .001, with more of a conservative ideology related to increased abortion stigma. Political ideology accounted for 29.1% of the variability in abortion stigma. Gender was entered in the second step, controlling for political ideology, and was found to be significant, b = -.11, SE= 1.29,p= .03, with women holding less stigma than men. Gender accounted for an additional 1.1% of the variability in abortion stigma, beyond the effects of political ideology. Finally, femininity was added into the third step, controlling for gender and political ideology, and significantly predicted abortion stigma, b = -.11, SE= .16, p= .03, and accounted for an additional 1.0% of the variance in abortion stigma. However, this finding was not in the predicted direction. We found a negative relationship, indicating that individuals with more femininity held less abortion stigma. This is counter to our original prediction, where we projected that individuals with more traditional feminine characteristics would hold more abortion stigma.

    These findings extend on previous work determining factors that predict abortion stigma. Having a better understanding of these factors combined influence will aid in decreasing abortion stigma. These results could help to create educational programs on sexual and reproductive health that can reduce abortion stigma and bias, and ultimately could lead to reducing negative health outcomes for individuals who have had an abortion.

  • Characteristics of Medicaid Dental Providers Who Provide Oral Health Services to Pregnant Women in Virginia by Hasib Zaman

    Characteristics of Medicaid Dental Providers Who Provide Oral Health Services to Pregnant Women in Virginia

    Hasib Zaman, Depts. of Bioinformatics and Computer Science, with Dr. Shilipa Naavaal, VCU School of Dentistry

    Introduction: Medicaid is a federal program that provides health insurance for low-income adults, children, pregnant women, and elderly adults in the United States. Virginia expanded their Medicaid, both financially and demographically, in January 2019 and currently has 1,317,981 individuals enrolled in Medicaid, which is an increase of 39.7% from 2018; however, within this expansion, there was no increase in budget for dental Medicaid. Although there are programs, such as Smile for Children, that cater to the oral health of pregnant women, many women do not use the available opportunities due to limited awareness and accessibility of services, as well as cultural factors affecting the quality of service (e.g., linguistic differences). Furthermore, only 39% of dentists nationwide accept Medicaid and/or children's health insurance, which not only discourages young families from seeking oral healthcare, but also limits their accessibility to these vital services. In order to clarify oral healthcare disparities for pregnant women, this study will explore the characteristics of providers who participate in Medicaid and provide oral health services to pregnant women in Virginia. Findings can inform policy focused on improving Medicaid participation among dental providers. Methods: The 2015-2018 Medicaid provider data was obtained through the State Department of Medical Assistance Services. The license numbers of each provider were collected using a public License Lookup tool available through the Virginia Department of Health Professions (VDHP). Additional provider characteristics (i.e., gender, age, years in practice, location) will be requested from the VDHP. Descriptive analysis is done to explore the characteristics of Medicaid providers, to map the distribution in the state of Virginia . Results: Analyses revealed that most providers were located in the Eastern and Northern regions of Virginia’s health districts (55%). These regions have the greatest number of providers that were involved in Medicaid, as it is a very suburban area containing a vast variety of demographics. Following these regions, there are approximately 11% of the providers in the Central region. Furthermore, the Northwest and Southwest regions combined to make up for approximately 34% of providers. Further analysis will be conducted in order to determine the socio demographic context of the providers within these regions. Discussions: During pregnancy, there is an increase in hormones that can affect one’s body’s response to plaque which can lead to increased tooth decay or gum disease. Therefore, there is a need to improve dental providers' participation in Medicaid to improve oral health services among pregnant women. These results have implications for workforce growth and development. Our study results suggest disparities in the distribution of dental providers by various characteristics. Findings provide an overview of the distribution of Medicaid, oral health providers throughout Virginia, with a particular concentration in the Northern region. Additionally, with regions such as Eastern and Northwestern that have a higher percentile of women that do not speak English fluently while having more providers that tend to be caucasian , there are demographic barriers between the two parties that inhibit women from seeking services.

    Background/Aims: Due to limited access to mental health care, many patients present to primary care with mental health concerns, such as depression and anxiety. Integrated primary care (IPC), an emerging practice model that integrates behavioral health providers with medical providers in primary care, has been demonstrated to improve patient outcomes. This project aims to characterize patients being seen in safety-net IPC, both demographically and clinically. Methods: The data were collected across three safety-net clinics in the Richmond area. The sample consisted of 96 adult patients: 68 female (71%), 24 male (25%), 1 non binary (1%), and 3 not collected (3%); 54 African-American (56%), 29 White (30%), 1 Asian (1%), 1 Other (1%), and 11 not collected (12%). Measures included a patient-completed checklist of patients’ behavioral health concerns, the PHQ-9 for depression, the GAD-7 for anxiety, and clinician-completed chart review for demographic factors. Results: Of the 72 patients who completed the GAD-7, patients reported 13 (18%) severe symptoms of anxiety, 11 (15%) moderate symptoms, 15 (21%) mild symptoms, and 33 (46%) subclinical symptoms. For the 37 patients who completed the PHQ-9, patients reported 7 (19%) severe depressive symptoms, 10 (27%) moderately severe symptoms, 12 (32%) moderate symptoms, 6 (16%) mild symptoms, and 2 (5%) subclinical symptoms. The six most commonly patient-reported problems were stress (n= 73), anxiety (n= 70), depression (n= 65), sleep (n = 55), grief (n = 53), and irritability (n= 53). When asked to rank their top three concerning problems, the five concerns most commonly ranked as top problems were: : (1) anxiety (n = 29), (2) stress (n = 28), (3) depression (n = 27), (4) sleep (n=16), and (5) weight (n=15). Further, 56 (58%) participants reported both depression and anxiety as among their top three concerns. Discussion: Anxiety and depression were reported by the majority of patients, with 33% experiencing at least moderate anxiety and 78% experiencing at least moderate depression. Additionally, anxiety and depression were cited as the third most commonly reported concerns, respectively, as well as ranked within the top three most concerning problems for most participants. Stress, anxiety, depression, and sleep were included in both the most commonly reported problems and the most common top three concerns of participants, suggesting that these concerns are both pervasive and troublesome for participants. Over time, this project will prioritize increasing sample size and tracking longitudinal trends. The continued study of safety-net IPC may allow for increasing access to behavioral health, identifying common behavioral health concerns in primary care, and meeting unmet patient needs.

    Motor Evoked Potential Recruitment Curves Indicate Neuroplasticity after Spinal Cord Injury

    Yasmina Zeineddine, Depts. of Biomedical Engineering and Anthropology, with Thibault Roumengous, Graduate Student in Biomedical Engineering, and Dr. Carrie Peterson, Dept. of Biomedical Engineering

    Introduction: Motor evoked potential (MEP) recruitment curves in response to transcranial magnetic stimulation across a range of stimulation intensities can provide insight into the condition of neural pathways to a muscle. Further, corticomotor reorganization associated with recovery of motor function may be reflected in changes in the MEP recruitment curve. At low TMS intensity, the MEP often consists of a single direct wave, whereas at higher stimulus intensities, the MEP amplitude increases due to recruitment of later indirect waves (I-waves). These late I-waves are thought to depend on trans-synaptic activation of corticospinal axons through excitatory interneurons. [1] In impaired patients, MEP recruitment curves can inform the development of individualized rehabilitation treatments, as curve irregularities can reveal specific deficits, and enhance our understanding of the neuroplastic changes that occur after injury. In comparing the biceps brachii recruitment curve of subjects with cervical spinal cord injury (SCI) to nonimpaired individuals, we hypothesized that individuals with SCI would have greater biceps excitability, and therefore greater RC slopes, due to the biceps cortical representation growing in response to triceps paralysis [2]. Materials and Methods: Ten nonimpaired (4 female, 6 male) and 5 impaired (3 female, 2 male) subjects consented to participate in the study. Subjects were seated and had their dominant arm positioned at a 90° elbow angle. EMG surface electrodes were placed on the biceps after being cleaned with alcohol wipes. The biceps cortical hotspot was determined as the area over the motor cortex where TMS evoked the largest MEP response. The resting motor threshold (RMT) was the lowest stimulus intensity required to elicit a 50μVpp MEP response in 3/5 trials. TMS was performed with a 126 mm diameter double cone coil and Magstim BiStim2 . MEPs were recorded from the BB and normalized by dividing by Mmax. Recruitment curves were recorded at stimulus intensities ranging from 80%- 160% of subject RMT in 10% increments. Pulse intensities were randomly administered with interstimulus intervals of 10 s. The data was recorded using Spike software and processed in Matlab. MEPs were excluded if they exceeded ±3 standard deviations of the mean response per intensity. Results and Discussion: The recruitment curve slopes for individuals with SCI, on average, were greater relative to the slopes of nonimpaired individuals. This was based on an analysis of MEPs between intensities of 100% and 140% RMT, wherein the slope was on average 5.13 across individuals with SCI, and 1.49 in the nonimpaired population. The greater slope in individuals with SCI suggests enhanced excitability of the biceps, which is consistent with previous studies showing greater cortical representation of non-paralyzed hand muscles relative to paralyzed muscles [2]. Conclusions: Our results indicate that cervical SCI promotes greater excitability in the muscles controlled by nerves rostral to the location of injury, and demonstrate neural plasticity following injury. The steeper slopes in individuals with SCI indicate greater recruitment of later I-waves. Whether increased recruitment of later I-waves is associated with greater cortical map area is unclear and will require further investigation.

  • Nutrigenomics: Using Sulforaphane Consumption as a Mechanism to Prevent Cardiovascular Disease through Epigenetic Regulation by Alisha Agrawal

    Nutrigenomics: Using Sulforaphane Consumption as a Mechanism to Prevent Cardiovascular Disease through Epigenetic Regulation

    Alisha Agrawal

    Cardiovascular disease is the leading cause of death in the United States. Diet composition and reduced expression of the transcription factor Nrf2 are both possible factors contributing to cardiovascular disease. As vitamin supplementation grows in scope and popularity, it is becoming common to replace vegetable consumption with multivitamins. The purpose of this research was to investigate how sulforaphane, an isothiocyanate found in its greatest quantities in broccoli, prevents cardiovascular disease through epigenetic regulation in order to promote the understanding that vitamin supplementation does not adequately replace the health benefits of phytonutrients found in vegetables. In order to investigate sulforaphane’s ability to prevent cardiovascular disease through epigenetic regulation, I studied scholarly journal articles that focused on experiments involving sulforaphane-induced activation of Nrf2 and the effects of Nrf2 activation such as up-regulation of antioxidant genes and phase II enzymes. Additionally, I studied articles examining sulforaphane-induced reductions in blood pressure and elimination of cardiac dysfunctions such as cardiac hypertrophy and decreased fractional shortening with the goal of identifying Nrf2 activation as the underlying mechanism. The results showed that up-regulation of antioxidant genes, signaling of phase II enzymes, lowered blood pressure, and elimination of cardiac dysfunctions were all a result of sulforaphane-induced activation of Nrf2. These results indicate that people who may be at risk for cardiovascular disease could benefit from including broccoli in their diet rather than using vitamin and mineral supplementation to replace vegetables that provide valuable phytonutrients.

  • A Comparative Study of Extreme Religious Nationalist Terrorist Groups in the United States by Colleen Arthur

    A Comparative Study of Extreme Religious Nationalist Terrorist Groups in the United States

    Colleen Arthur

    The aim of this paper is to conduct a comparative study of Radical Right Wing terrorism and Radical Islamic terrorism both of which are categorized under the Religious Nationalism/Extremism typology of terrorism. In order to compare and contrast the two fairly, I broke down the ideology, motives, methods, and the demographic profile of members of both Radical Right Wing and Radical Islamic terrorism then provided examples of different groups that fall within those categories in order to effectively illustrate the striking similarities of the two categories that have been addressed and condemned differently by the United States. Then I had analyzed how and why the United States has approached groups that fall under Radical Right Wing terrorism vastly different than groups under Radical Islamic terrorism even though both fall under the same Religious Nationalism/Extremism category of terrorism. This comparative study is also being conducted to examine why the United States did not have the same reaction to Radical Right Wing terrorist groups before the September 11th attacks as it did to the Radical Islamic groups since Radical Right Wing groups had committed the most violent acts in the United States prior to September 11th 2001. Lastly, I will also briefly discuss the present day social implications associated with the difference of treatment between the two terrorist groups.

  • Effects of Nostalgia on Responses to Negative Feedback by Michaela K. Avino, Thomas Cotter, Simron Richard, Athena Cairo, and Jeffrey Green

    Effects of Nostalgia on Responses to Negative Feedback

    Michaela K. Avino, Thomas Cotter, Simron Richard, Athena Cairo, and Jeffrey Green

    Nostalgia is a bittersweet emotion evoked by memories of cherished personal experiences. Though nostalgia is a self-focused emotion, it has many interpersonal effects as well. Feeling nostalgia increases feelings of social connectedness and self esteem, and may protect against negative effects of existential threat (Wildschut et al., 2006). However, less is known about the extent to which nostalgia relates to anger and aggression. We hypothesized that nostalgia would buffer against the effect of negative feedback on feelings of anger and motivation to aggress. Undergraduate students wrote about a nostalgic or objective memory, and then received negative feedback about another personal writing project. Participants reported their feelings of anger, then had the opportunity to punish the individual who gave them negative feedback by administering loud noise blasts in a competitive game. We discuss the results and real-world implications of these findings.

  • Effect of Energy Metabolism on NF-kB activity in Ovarian Cancer by Simren K. Bagri

    Effect of Energy Metabolism on NF-kB activity in Ovarian Cancer

    Simren K. Bagri

    NF-kB is a transcription factor involved in cancer cell growth and survival. The activation of NF-kB can be assessed by monitoring phosphorylation of RelA p65 at Ser-536, which is a surrogate of the NF-kB transcription factor activation. The objective of this study was to determine if the loss of ATP leads to NF-kB deficiency and thus, apoptotic cell death of “bad” cells in ovarian cancer cells. The independent variables were metformin (Met), an anti-diabetic medicine, another compound MinB functionally similar to Met and a glucose transporter inhibitor BAY-876. The dependent variables were the resulting effect of Met and MinB on phosphorylated AMPK at Thr-172 (marker of ATP loss) and RelA p65 at Ser-536 (marker of NF-kB activation). In each experiment, AMPK and RelA phosphorylation were tested by treatment of ovarian cancer cell lines with Met, MinB, BAY-876, Met+BAY-876, MinB+BAY-876. Western blotting was performed to determine the phosphorylation levels of AMPK and RelA p65. For two gels, the process was repeated. In each gel, Met or MinB treatment leads to thicker bands of AMPK-p, indicating decrease in cellular ATP levels following treatments. The effect of Met, MinB, or BAY-876 on RelA p65 was limited. However, co-treatment of Met or MinB with BAY-876 caused strong inhibition of NF-kB, as reflected by reduction in RelA p65-p. These results suggested that ATP deficiency together with inhibition of glucose transport cause inactivation of NK-kB. Future research will be conducted to study the effects of these compounds or their combinations on ovarian cancer cell growth and survival against from apoptosis.

  • A Comparison of Two Methods of Quantifying Mating Success in Low Density Gypsy Moth (Lymantria dispar) Populations by Alexandra Barry, Hannah Byrne, and Derek M. Johnson

    A Comparison of Two Methods of Quantifying Mating Success in Low Density Gypsy Moth (Lymantria dispar) Populations

    Alexandra Barry, Hannah Byrne, and Derek M. Johnson

    The gypsy moth (Lymantria dispar) is a defoliating pest native to Europe and invasive to North America. The gypsy moth is subject to depressed mating success in low density populations, which may restrict spread of the forest pest. Research focusing on gypsy moth density as it relates to mating behavior has often used counts of males caught in pheromone-baited delta traps as a proxy to estimate the probability of female mating success. The purpose of this project was to determine whether pheromone trap counts provide accurate estimates of female mating success probability, by comparing data gathered from pheromone-baited delta traps to data gathered on mating success of tethered females. To determine the relationship between number of males caught in delta traps and the probability of successful mating, male catch counts in traps were compared to mating success of tethered females in a mass male release experiment. The relationship between delta trap catch of males and female mating success was quantified using a Bayesian framework, which explicitly incorporates uncertainties in the model. Vegetative cover in the study plots was reduced to a single measure through principal components analysis and included as an independent factor in the model. The data suggest that delta traps reduce the male’s ability to find a female by 67%; thus, results garnered from delta trap catch counts tend to underestimate the underlying ability of males to locate and mate with females. Thick understory vegetation further reduced the male’s ability to locate a female, and further reduced the effectiveness of delta traps. Future studies that seek to use counts of males in pheromone-baited traps as a proxy for mating success should consider using an adjustment factor to equate the two methods of quantifying reproductive behavior in the gypsy moth.

  • College Student Alcohol Use and Engagement in Prevention Programming by Alexis H. Branch, Shimona Kumar, and Christina McGrath

    College Student Alcohol Use and Engagement in Prevention Programming

    Alexis H. Branch, Shimona Kumar, and Christina McGrath

    Social problems and adverse consequences have been associated with risky alcohol use (Paschall et al, 2015). Personalized Normative Feedback (PNF) has been utilized to address these problems (White and Hingson, 2014) by comparing students’ alcohol use to campus or national norms (Butler et al, 2009). The current investigation sought to understand differences in alcohol use behaviors in freshmen who did and did not report completion of a personalized feedback intervention (PFI) in a diverse sample of college students from the Spit for Science (S4S) project. S4S is a campus-wide, longitudinal study on the genetic and environmental factors that contribute to mental health and substance use outcomes in college students. Freshmen (N=1,168) completed surveys in the fall and spring; in the spring, whether or not students completed a PFI during their freshman year was assessed. Alcohol use disorder (AUD) symptoms and grams of ethanol consumed were calculated for participants who reported completing an online PFI for alcohol use (n=365) and for those who did not (n=803). We hypothesized that (1) PFI freshmen would exhibit greater alcohol consumption and AUD symptoms in the fall (pre-PFI), and (2) students in both groups would exhibit equal rates in the spring (post-PFI). There was sufficient evidence to support the fall hypothesis: students in the prevention group exhibited higher levels of alcohol consumption (t=1.39, p<0.001) and AUD symptoms (t=2.42, p=0.031). The spring hypothesis was not supported: PFI students exhibited higher levels of alcohol consumption (t)=1.4373, p<0.01) and AUD symptoms (t=2.09, p < 0.01). Future research could examine whether the results may vary by ethnicity or other demographic characteristics.

  • How Personal Names Shape the Way Society Sees People as Individuals in the United States. by Rand Gabriel M. Buenaventura

    How Personal Names Shape the Way Society Sees People as Individuals in the United States.

    Rand Gabriel M. Buenaventura

    In a world where people are disadvantaged by first impressions and implicit bias, names factor a lot into a person’s successes in life. Whether it be first names, last names, the number of middle initials, the gender and racial implications of a person’s name, and societal standards surrounding names and naming systems, there are multiple ways names shape a person’s identity. Thus, it is important to ask how personal names shape the way people are seen as individuals in the United States and contribute to their identity. Names are a trait that people are born with, usually determined before anything is known about that person. Research for this paper involved exploring articles about the various aspects of names, as well as investigating the psychosocial effects they have on people. A thorough understanding of the impact of names was found. It was expected that there would likely be implications surrounding only race and gender signaling names, yet it was discovered that there are much more biases that names can signal based on the contents of that person’s name. From a person’s educational worth to an association with lesser valued societal qualities, names allow people to form assumptions and draw conclusions without actively trying to. Immigrants in the United States have even faced less adversity upon anglicizing their name, simply because it allows them to more easily blend in and assimilate. As a result, bringing together this research allows a more holistic understanding of implicit bias. Broadly, this can further be applied to explaining why certain people have more privilege than others. Just like how teachers can treat certain individuals differently based on their name, affecting how that individual receives education, societal stereotypes can similarly impose different attitudes due to how names are perceived.

  • Enhancing Handbag Design Through Anti-Counterfeit Technology by Kylie R. Carroll

    Enhancing Handbag Design Through Anti-Counterfeit Technology

    Kylie R. Carroll

    In recent years, the presence of counterfeit goods has become a $600 billion global industry, encompassing markets ranging from designer luxury goods to pharmaceuticals. This paper identifies the threat that this increased counterfeit presence poses on the high-end handbag market. Increased counterfeit quality is significantly contributing to the deception of consumers when attempting to purchase authentic designer handbags. In response to this increased threat, numerous designer brands have begun to adopt anti-counterfeit technologies with both track-and-trace and authentication agendas, to enhance the security of their products against the counterfeit industry. Several variations of anti-counterfeit solutions exist, and this paper specifically examines the effectiveness of the security and authentication factors of hologram, digital watermark, and Radio Frequency Identification solutions within a designer handbag application. After careful analysis of the various anti-counterfeit solutions available in the contemporary market, this paper concludes that overt and covert combination technologies with a two-factor-authentication approach are the most effective in terms of security and authentication capabilities. In conjunction with an anti-counterfeit efficacy analysis, this paper proposes an anti-counterfeit technology adaptation with the aim of elevating both security and design aesthetic. Design that favors functionality has recently gained traction in the fashion industry and incorporating anti-counterfeit technology into handbag design in a visually enhancing manner is the ultimate method of furthering both form and function in a technologically advanced world.

  • Using Crosslinked Hyaluronic Acid (HA) and Collagen Scaffolds with Sustained Brain-Derived Neurotrophic Factor (BDNF) Release for Post-SCI Nerve Regeneration by Panth Doshi

    Using Crosslinked Hyaluronic Acid (HA) and Collagen Scaffolds with Sustained Brain-Derived Neurotrophic Factor (BDNF) Release for Post-SCI Nerve Regeneration

    Panth Doshi

    Traumatic events resulting in spinal cord injuries (SCIs) often leave people paralyzed or with partial loss of motor function. The physical disabilities arising from traumatic events prevent people from functioning at the same level as pre-injury. My work aims to identify a plausible method to overcome the inhibitory post-SCI environment and to regenerate nervous tissue in order to restore neural function and, subsequently, motor function. I identified components of a new, hypothetical nerve scaffold based on the immune response after SCIs and the efficacy of currently used scaffolds for nerve regeneration. Hyaluronic acid (HA) polymer scaffolds and collagen-based scaffolds are individually effective in counteracting the post-SCI inhibitory environment and inducing neurofilament growth. In addition, sustained release of brain-derived neurotrophic factor (BDNF) into the lesion site has shown to supplement, and even augment, the physical and functional recovery achieved through the HA and collagen-based scaffolds. Thus, I propose the testing of a crosslinked HA and collagen scaffold with sustained BDNF release through BDNF-bound collagen binding domain and BDNF embedded PLGA microspheres as a more viable and effective method for spinal nerve regeneration in order to restore neural and motor function.

  • The Forensic Characterization of Bacterial and Fungal Organisms in Traditional Chinese Medicine by Julia Grzymkowski, Christopher J. Ehrhardt, Justin L. Poklis, and Michelle R. Peace

    The Forensic Characterization of Bacterial and Fungal Organisms in Traditional Chinese Medicine

    Julia Grzymkowski, Christopher J. Ehrhardt, Justin L. Poklis, and Michelle R. Peace

    There has been an increase in use of Traditional Chinese Medicine (TCM) in the United States because they are less expensive and believed to be more effective with less adverse effects in comparison to traditional pharmaceutics. Therefore, sales have increased in the US, despite articles and case studies demonstrating the dangers, such as injury and death, related to TCM, stemming from improper labelling, toxic contaminants, and, in some cases, the presence of pathogenic bacteria. The aim of this study was to perform a survival experiment to demonstrate the importance of proper herbal brewing technique and to conduct a molecular and biochemical survey of microorganisms present on eleven Chinese herbal samples. The survival study compared Chinese brewing preparation and American brewing preparation by fortifying the herbal mixture with known bacteria and assessing its survival after brewing. The American brewed herbal tea was calculated to contain upwards of 3000 CFU (colony forming units)/mL, where the Chinese brewed herbal tea contained roughly 50 CFU/mL. FAME (Fatty Acid Methyl Ester) analysis was performed on the herbs to characterize any microorganisms present on the plant material already, following purchase. Strains within the Bacillus genus were identified in nearly all eleven of the herbal samples. These included B. subtilis and B. megaterium. Organisms belonging to the Bacillus ACT group (anthracis, cereus, thuringiensis) were identified in five out of eleven herb cultures as evidenced by the large ratio of 15:0 iso to 15:0 anteiso fatty acid biomarkers. Nine out of eleven herbal specimens also exhibited fungal biomarkers such as polyunsaturated 20:4 ω6,9,12,15c, and 18:3 ω6c (6,9,12).

    Adolescent Expressive Reluctance Exacerbates Risk for Substance Use Following Daily Hassles

    Chad M. Hensberger, David W. Sosnowski M.S., Wendy Kliewer Ph.D, and Kristina McGuire M.S.

    Previous research has established a link between adolescent’s perceived daily hassles and subsequent adjustment, but less is known about factors that exacerbate this relationship. The purpose of the present study was to identify if adolescent’s reluctance to express emotions moderated the association between their perceived daily hassles and subsequent substance use (i.e., alcohol, marijuana, tobacco). Cross-sectional data were obtained from a larger study that examined the effects of exposure to community violence among low-income, urban adolescents (N = 260, Mage = 14.14, SD = 1.62 years; 92% African American; 54% female). Linear regression analyses controlling for adolescent age, biological sex, and previous levels of drug use and daily hassles revealed that expressive reluctance moderated the association between perceived daily hassles and adolescent substance use. Specifically, for adolescents who were least likely to express their emotions, increases in perceived daily hassles were associated with significant increases in substance use. Further examination of domain-specific hassles revealed that expressive reluctance moderated the effects of academic, parental, and general neighborhood hassles on drug use, while no significant effects were detected for hassles related to friends or neighborhood danger. The present findings clarify which perceived daily hassles adversely affect adolescents, and how emotional expression can play an integral role in determining risk for poor coping behaviors.

  • The Silver Lining: A Novel, Inkjet-Printed Mesh Coplanar-Slot Antenna for the UHF Band by Anastasios C. Karles

    The Silver Lining: A Novel, Inkjet-Printed Mesh Coplanar-Slot Antenna for the UHF Band

    Anastasios C. Karles

    The Federal Communications Commission (FCC) is opening up frequencies within the television range (400MHz to 700MHz) of the Ultra High Frequency (UHF) band for use in emerging technologies, such as cognitive radio networks and machine-to-machine communication. In order for manufacturers to produce affordable antennas that can be used in these emerging technologies, inexpensive antennas are required that meet these new spectrum needs. This paper presents a mesh coplanar-slot bowtie patch antenna fabricated using commercially available inkjet-printing technology. Two antennas were fabricated: a 27x21cm copper FR4 antenna with .25mm lines and a 27x21cm silver antenna with 2mm lines fabricated using inkjet-printing. The copper antenna was iteratively designed in High Frequency Software Simulator (HFSS) and measured using a network analyzer. Simulations and measured results, which show good agreement, verify the viability of merging the mesh and coplanar-slot topologies. The silver antenna is a variation of the copper antenna that was iteratively altered in HFSS until the desired bandwidth was achieved. Simulations and measured results, which show good agreement, verify the viability of inkjet-printing as a fabrication method. The radioelectrical performance of the antennas were also compared to each other. Although there was slight variation between the resonant frequency and bandwidth, an adequate agreement was observed between the two antennas. This demonstrates the feasibility of using inkjet-printing as a quick, efficient method to fabricate UHF antennas that can take advantage of emerging spectrum and be used in applications such as cognitive-radio-networks and machine-to-machine communication.

  • Influence of Gluteus Medius Strength on Interlimb Asymmetry in Female Recreational Runners. by Morgan Meyer, Olivia Moody, Kathryn Harrison, Gregory Crosswell, and Bhushan Thakkar

    Influence of Gluteus Medius Strength on Interlimb Asymmetry in Female Recreational Runners.

    Morgan Meyer, Olivia Moody, Kathryn Harrison, Gregory Crosswell, and Bhushan Thakkar

    PURPOSE: Running-related injuries are most often single-sided and are partially attributed to lower limb movement and loading asymmetries.1 Gluteus Medius (GM) plays a significant role in lower limb alignment, especially in the frontal and transverse planes by its influence on the pelvis and the femur.2 Female runners are more prone to GM weakness which has been proposed to be a risk factor for overuse injuries.3 These strength deficits contribute to abnormal lower limb kinematics and kinetics during dynamic tasks like running and jumping.4 These changes include an increase in peak hip adduction angle (HA), hip internal rotation angle (HI), knee abduction moment (KA) and rearfoot eversion angle (RE).4 Symmetry Angle (SA) is a commonly-used, robust measure of determining symmetry.1 No study has evaluated the role of unilateral GM strength on interlimb asymmetry for HA, HI, KA and RE during running. We hypothesized that female runners with stronger GM would demonstrate decreased interlimb asymmetry for HI, HA, KA and RE during running. METHODS: Thirty healthy female recreational runners (Age: 35.40±10.52 yrs, Height: 1.66±0.06 m, Weight: 61.61±7.31 kg) running at least 10 km per week participated in this study. Isometric GM strength was measured using a handheld dynamometer for the right lower limb and participants were divided into two groups of stronger and weaker. 3D gait analysis was conducted as participants ran on an instrumented treadmill at 2.98 m/s. Peak HA, HI, KA and RE were generated for the bilateral lower extremities and interlimb asymmetry using SA was calculated for all variables. A Shapiro-Wilk test for normality was conducted and it showed that all variables were not normally distributed. Wilcoxon Two-Sample Test was performed to look at differences between the two groups for HA, HI, KA and RE. RESULTS: Female runners with weaker GM demonstrated significantly increased asymmetry for HA (18.80±24.11 vs 12.20±24.11 %, p=0.02), HI (18.47±24.11 vs 12.53±24.11 %, p=0.03), and KA (18.33±24.11 vs 12.67±24.11 %, p=0.04). For RE, the weaker group had greater asymmetry (16.13±24.11 vs 14.87±24.11 %, p=0.35), but the relationship was not significant. CONCLUSIONS: This study suggested that runners with weaker GM on one side exhibited increased interlimb asymmetry during running for certain kinematic and kinetic variables. Future studies should determine how unilateral and bilateral strength deficits contribute to interlimb asymmetry and running biomechanics in healthy and injured runners.

    TP73 is a member of the TP53 family of proteins that acts as a transcription factor to help regulate cellular distress. This tumor protein may play a dual role as a tumor suppressor and tumor promoter. The TP73 gene is mapped to chromosome 1p36, a frequently deleted region in neuroblastoma and other types of tumors. While mutations in the TP53 gene are commonly known to cause noxious cancers, 30% of cancers result from the overexpression of TP73. In our lab, we examined the role of TP73 in the formation of neuroblastoma, a type of cancer that begins in the nerve tissue atop the adrenal gland of kidneys in children. Normal fibroblast cell lines (HS27) and tumor kidney cells (IMR32 and SK-N-SH) were grown in their respective growth media. DNA and RNA of both cell types were extracted using standard procedures. RNA expression was analyzed by RT-PCR and DNA methylation was analyzed by bisulfite sequencing. The expressions of TP73 gene and its protein were analyzed by gel electrophoresis and immunohistochemistry respectively. We found that the TP73 gene was expressed in all of the neuroblastoma cells, but there was no evidence of its expression in the normal cell lines. Subsequent methylation studies revealed that TP73 was expressed in neuroblastoma cells but not in non-cancerous cells due to silencing by DNA methylation. In conclusion, the absence of TP73 in normal cells is in part due to DNA methylation implying that TP73 plays a role in the promotion and/or progression of carcinogenesis.

    The aim of this study is to observe cell proliferation, cell viability, apoptosis, and autophagy on acute myeloid leukemia (AML) cell lines, NB4 and U937, with the drug repurposing of mefloquine (MQ). Methods such as the 3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay and trypan blue staining have shown a decrease in live cells with high concentrations of mefloquine. Using their average perspective IC50 values of MQ concentration, Western blotting was applied by means of apoptosis and autophagy markers to determine if the induction of apoptosis and inhibition of autophagy was present in MQ-treated AML cells. The experiment will be continued with more cell lines, drugs, and other means of protocol in order to contribute to cancer therapy.

  • Examination of Methylation Sites for Forensic Age Determination from Semen by Christian Renwick and Sarah J. Seashols-Williams

    Examination of Methylation Sites for Forensic Age Determination from Semen

    Christian Renwick and Sarah J. Seashols-Williams

    Methylation Sensitive High-Resolution Melt (MS-HRM) is based on quantitating the melt curve from an experimental sample against a standard of known methylation levels. Whereas most applications of age prediction using methylation markers are based upon pyrosequencing or SNaPshot technologies, these analysis methods are both cost and instrumentation prohibitive. This study sought to use to the varied methylation status of the ELOVL2 and FHL2 alleles, both having known correlation with age (Hamano et. al.), in a labor and time efficient manner to develop an age prediction model. A non-linear regression and standard curve was compiled from the methylation status in a sample (n=7) of extracted semen samples and compared to chronological age. The methylation status of ELVOL2 and FHL2 from each sample was obtained, with the conclusion that no correlation in methylation percentage and biological age existed for this sample of individuals aged 20-33. The principal objective of this study, to expand the application of MS-HRM age prediction from blood to other body fluids, will need further testing using larger sample sizes and broader age ranges prior to application in forensic casework.

    Speech Recognition Technology: Improving Speed and Accuracy of Emergency Medical Services Documentation to Protect Patients

    Tan T. Tran

    Because hospital errors, such as mistakes in documentation, cause one sixth of the deaths each year in the United States, the accuracy of health records in the emergency medical services (EMS) must be improved. One possible solution is to incorporate speech recognition (SR) software into current tools used by EMS first responders. The purpose of this research was to determine if SR software could increase the efficiency and accuracy of EMS documentation to improve the safety for patients of EMS. An initial review of the literature on the performance of current SR software demonstrated that this software was not 99% accurate and therefore, errors in the medical documentation produced by the software could harm patients. The literature review also identified weaknesses of SR software that could be overcome so that the software would be accurate enough for use in EMS settings. These weaknesses included the inability to differentiate between similar phrases and the inability to filter out background noise. To find a solution, an analysis of natural language processing algorithms showed that the bag-of-words post processing algorithm has the ability to differentiate between similar phrases. This algorithm is the best suited for SR applications because it is simple yet effective compared to machine learning algorithms that required a large amount of training data. The findings suggested that if these weaknesses of current SR software are solved, then the software would potentially increase the efficiency and accuracy of EMS documentation. Further studies should integrate the bag-of-words post processing method into SR software and field test its accuracy in EMS settings.

    Community Engagement for Health and Wellness in Aging Populations: Institute for Inclusion, Inquiry, and Innovation (iCubed)

    Naziirah Vines

    The Virginia Commonwealth University (VCU) Institute for Inclusion, Inquiry and Innovation (iCubed) is a cutting-edge institute focused on creating collaborative connections between the university and Richmond through innovative academic and research programs. iCubed consists of six transdisciplinary cores which unite faculty members and students to work with key community members to develop holistic solutions to 21st century urban challenges. One of these cores, the Health and Wellness in Aging Populations (HWAP) core, was designed to educate and assist low-income older adults in becoming self-sufficient in navigating healthcare services. The HWAP core is centered within the Richmond Health and Wellness Program, an interprofessional care coordination and wellness service that serves Richmond’s low-income senior housing communities. As part of its inaugural mentorship program, iCubed created the Commonwealth Scholars Program (CSP) to pair academically talented undergraduate students with faculty members in the HWAP core to conduct research on aging populations in Richmond. As part of their responsibilities, the students were tasked with interviewing HWAP core faculty members to assess their perceptions of the core’s mission and progress. As such, the current study summarizes the findings from these interviews and offers guidelines for future directions.

    CSP conducted interviews with HWAP core faculty members (N=10) to establish a multiperspective vision of HWAP core objectives. Interviewed members come from the following VCU Departments: Family and Community Health Nursing/School of Nursing, Pharmacotherapy and Outcomes Science/School of Pharmacy, Family Medicine and Population Health/School of Medicine, Gerontology/School of Allied Health Professions, Adult Health and Nursing Systems, and Urban and Regional Studies, Planning/L. Douglas Wilder School of Government and Public Affairs. Each interview lasted approximately 10 minutes and was recorded into an electronic document. Themes from the interviews were identified and main themes are described. Coded themes indicated that the HWAP core aims to deliver care, offer education, and help aging clients navigate the healthcare system. Faculty members noted that HWAP core’s engagement with the community aims to build trust with community members and create lifelong partnerships. Findings indicated that the HWAP core has the potential to improve the quality of life for older adults and empower community members to maintain their independence and age in place. Future opportunities for the HWAP core include training older adults to become community health workers to be truly vested within the mission and actions of the core. In conclusion, the HWAP core aims to improve the lives of low-income older adults in Richmond and does so by connecting VCU researchers and students with community members.

  • Does The Rock Really Rock? The effects of using a celebrity in a B2B advertisement. by Mary Widmer and Amanda Heah

    Does The Rock Really Rock? The effects of using a celebrity in a B2B advertisement.

    Mary Widmer and Amanda Heah

    Background: Previous studies have investigated the relationship between the content of advertisements and the effect it has on viewers’ engagement and retention. Seno and Lukas (2007) looked into this phenomenon and stated, “research has found that celebrities are more effective than other types of endorsers” (p. 121). Another study by Tantiseneepong, Gorton, and White (2012) found that celebrity endorsers “can improve the effectiveness of marketing communications, by enhancing a product’s image, attracting attention and improving recall rates” (p. 57).

    Research Questions:This research addresses relationships with having a celebrity in a B2B advertisement. This study sought to answer the following questions: a) How does the usage of a celebrity in a B2B advertisement affect visual fixation? b) How does the usage of a celebrity in a B2B advertisement affect retention of product information presented in the advertisement?

    Methods: The eye-tracking data was collected in the Customer Experience Lab (a School of Business behavioral research lab featuring two eye-tracking stations). The participants for this research were 37 qualified business managers. This was a between subjects experimental design in which one cell was shown a shredder advertisement featuring a celebrity and the other cell was shown a shredder advertisement with a stock photo model. After viewing their respective advertisements, participants completed a short survey to evaluate their experience.

    Conclusion: In general, the results indicate that the usage of a celebrity brings greater attention to the advertisement. The data shows that participants spend more time looking at the advertisement with the celebrity in comparison to the advertisement with the stock photo model. Retention of product information included in the advertisement is greater when a celebrity is not present in the advertisement.
