Analysis Of Economic And Pandemic Forces On U.S. Stock Market Index, S. Keith Lowe, Julie Staples, Cassabdra Ward

Journal of Business, Industry, and Economics

Over the past century, research has been prevalent in the economic and financial literature on developing models to assist in the prediction of stock market price and stock market indices. Stock market price prediction is a complicated process, which has produced and conceptualized several theories regarding stock markets over the years. Most of these theories either try to explain the nature of stock markets or try to explain whether the markets can be manipulated through inefficiencies which often lead to financial gain for investors. Most of these past prediction models have utilized some form of quantitative-based regression analysis, including logit, …

Journal of Business, Industry, and Economics

This paper addresses the large and growing pay gap between executives and employees in large corporations by considering the need for a private sector maximum wage law in the United States. The first section of the paper presents evidence that suggests the United States has a large pay gap compared to other countries and that the pay gap in the United Statesis growing over time. The second section of the paper presents a review of court cases and legislative actions that include the ineffectiveness of derivative lawsuits, the lack of new legal doctrines to address pay gaps, the general failure …

Common Error In Brand Perception Survey Research: Cell Assignment Strategies, Timothy Norvell, Erin Gillespie

Journal of Business, Industry, and Economics

Today marketing researchers are faced with many challenges in the pursuit of high quality, affordable survey data collection. Frequently researchers would like to measure the perceptions of multiple products or brands and then gather detailed information about each. However, when respondents qualify to answer questions about many of the entities (i.e., brands or products), there may not be enough time to answer questions about all of them. It becomes even more challenging to achieve the necessary sample size per entity when invariably some of the entities are of low incidence. Therefore, the researchers typically assign the respondents to answer questions …

The Impact Of A Policy Change Requiring Embedded Video Lectures In Online Microeconomics Courses, Lane Boyte-Eckis, Steven J. Lee, Anand Krishnamoorthy

Journal of Business, Industry, and Economics

This paper aims to study whether a pilot policy change requiring asynchronous video lectures (embedded recorded lectures) improves student performance in undergraduate online microeconomics courses. The researchers used time series regression analysis to determine whether there was a statistically significant difference before and after the intervention of recorded lectures in undergraduate microeconomic courses. Research results indicate that recorded lectures do not significantly improve student outcomes in undergraduate online microeconomics courses. The research results have implications that extend beyond the current study.

Using A Non-Destructive Method To Estimate The Number Of Contributors And Predict Dna Yield In Touch Dna Mixtures, Christin Lee

Master of Science in Forensic Science Directed Research Projects

Touch DNA samples are low templates and often are mixtures, making them typically one of the most difficult types of evidence to interpret. Short tandem repeat analysis is a standard method to estimate the number of contributors and DNA yield for each contributor; however, there are some limitations. Applying a non-destructive pre-DNA analysis technique that provides information about the touch DNA may improve the casework process. Antibody probes to hormones such as testosterone and dihydrotestosterone (DHT), and proteins including cytokeratins (CK) inside epidermal cells, have been demonstrated to produce a personalized signature for human touch cell populations. Testosterone, DHT, and …

The Analysis Of Commercially Available Kratom Products In Richmond, Virginia, James H. Fleming Jr

Master of Science in Forensic Science Directed Research Projects

Kratom is a novel psychoactive substance that has gained popularity within the past ten years. Originating from Southeast Asia, the leaves of the Mitragyna speciosa tree contain two principal alkaloids, mitragynine and 7-hydroxymitragynine, that play a key role in opioid-like effects. Twenty-nine kratom products were obtained from tobacco shops in the Richmond, Virginia area, including powders, teas, capsules, extracts, and a carbonated beverage. Samples were analyzed using Direct Analysis in Real Time-Mass Spectrometry (DART-MS) for kratom alkaloids, labeled ingredients, and other possible organic compounds. Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) was used to quantitate aluminum, arsenic, copper, iron, magnesium, nickel, …

Identification Of The New Synthetic Opioid Bucinnazine And Its Metabolites Using Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Karissa N. Resnik

Master of Science in Forensic Science Directed Research Projects

In the past 20 years, the rate of opioid use increased drastically in the United States. The country has experienced an enormous number of deaths caused by opioid overdose, opioid use disorder (OUD), as well as other harms as a consequence of the high numbers of opioid prescriptions. Fentanyl, a well-known synthetic opioid, has been a contributor to the opioid crisis since 2013 due to its popularity in clinical and illicit use. It has a high potency, which makes it an effective analgesic but a dangerous illicit substance. A new synthetic opioid, bucinnazine, has recently become a new black-market opioid …

Development Of A Loop-Mediated Isothermal Amplification (Lamp) Assay For Detection Of Mirnas, Alisha B. Whelan

Master of Science in Forensic Science Directed Research Projects

Body fluid identification serves a vital role in contextualizing biological evidence received in forensic laboratories. While several fluids can be presumptively detected using immunological or catalytic tests, these tests are susceptible to false results and have limited sensitivity. True confirmatory testing is still somewhat limited in forensic laboratories. With the advancement of DNA typing technologies, laboratories can develop DNA profiles from trace amounts of sample, increasing the demand for sensitive and accurate body fluid detection. This project proposes using loop-mediated isothermal amplification (LAMP) as a method to rapidly detect microRNAs (miRNAs) that are differentially expressed in various body fluids with …

Impact Of 1,4-Dithiothreitol (Dtt) On Microbial Community Structures Associated With Human Semen Samples, Christian R. Blaise

Master of Science in Forensic Science Directed Research Projects

Body fluid identification (BFID) is one of the most important steps in forensic science as it provides important context to how DNA analysis should be performed on biological samples found at the scene of a crime. Many scientific methods on BFID have been developed over the years with respective benefits and flaws. One emerging method in recent years is microbial signature based BFID. This method uses the same DNA extract that is utilized for human DNA profile generation for microbial analysis. Although DNA is extracted from all body fluid samples without any additional steps, extraction of human DNA from semen …

Determination Of Cotinine Concentration In Urine By Liquid Chromatography Tandem Mass Spectrometry, Allison Beckett

Master of Science in Forensic Science Directed Research Projects

Tobacco use can cause lasting health conditions which can lead to death. Tobacco exposure comes from obvious sources like smoking or chewing tobacco, however these are not the only administration methods. Secondhand smoke exposure can affect even those who choose not to expose themselves to tobacco, which also opens them to the health issues that come along with tobacco use. Tobacco contains many different compounds, one of which is nicotine (Kataoka, 2009). Although nicotine is the most abundant compound in tobacco, it does not stay in the body for long periods of time. Nicotine metabolizes into cotinine which is more …

Assessing The Detectability Of Cannabinoid Analogs (Delta-8 Thc, Delta-10 Thc And Cbd) And Their Major Metabolites In Six Commercial Cannabinoid Urine Screening Kits, Ashley A. Pokhai

Master of Science in Forensic Science Directed Research Projects

Background:

There has been an exponential surge in the presence and use of cannabinoids since the federal legalization of hemp (Agricultural Improvement Act of 2018), which involves the legalization of medical use, adult recreational use, and decriminalization of cannabis in several states. This growth is not only attributed to ∆9-tetrahydrocannabinol (∆9-THC) and cannabidiol (CBD), the most abundant phytocannabinoid components of cannabis and hemp, respectively, but with many other emerging THC analogs. Structurally, these analogs are similar to ∆9-THC, yet very little information is available about their potency and even less information is available regarding their detectability using commercially available cannabinoid …

Sentiment Without Sentiment Analysis: Using The Recommendation Outcome Of Steam Game Reviews As Sentiment Predictor, Anqi Zhang

Electronic Theses and Dissertations

This paper presents and explores a novel way to determine the sentiment of a Steam game review based on the predicted recommendation of the review, testing different regression models on a combination of Term Frequency-Inverse Document Frequency (TF-IDF) and Latent Dirichlet Allocation (LDA) features. A dataset of Steam game reviews extracted from the Programming games genre consisting of 21 games along with other significant features such as the number of helpful likes on the recommendation, number of hours played, and others. Based on the features, they are grouped into three datasets: 1) either having keyword features only, 2) keyword features …

This dissertation divides this topic into 4 sub-topics. The first sub-topic explores how PJBL …

Employment Status For “Essential Workers”: The Case For Gig Worker Parity, Miriam A. Cherry

All Faculty Scholarship

This Article explores what I call the “essential worker paradox”: During the pandemic, gig workers have been recognized as providing critical and important services. At the same time, the law has yet to recognize gig workers fully and to commit to providing them with the same basic protections as employees. The Article argues that the stark difference in treatment between gig workers and regular employees has long created unfairness. While views of gig work as a side hustle or work driven by customer convenience may have prevailed in the past, now the meal delivery driver and the on-demand grocery shopper …

Acknowledging The Racist Roots Of Disinvestment And Abandonment: How Local Government Can Set The Stage For Change, Dana M. Malkus

All Faculty Scholarship

Disinvestment and associated property abandonment are defining features of many post-industrial legacy cities. While the reasons are varied and complex, racist law and policy are at the root. Though abandoned properties negatively affect an entire city, their effects usually disproportionately fall on neighborhoods of color. Law and policy have been major drivers of how such neighborhoods look and feel today. Because law and policy have been part of the problem, they are also a necessary part of the solution.

This kind of large-scale, multi-disciplinary problem is beyond the ability of a single institution or sector to address. Stakeholders such as …
