Veterans are approximately 30% more likely than non-veterans to suffer from severe hearing impairment. Tinnitus, or ringing in the ears, which is increasingly common among military service men and women, has been linked to significant cognitive and psychological impairment and can be worsened by the same sounds that trigger post-traumatic stress disorder (PTSD). In fact, tinnitus and PTSD often present as comorbidities, and recent studies suggest these two disorders may share a common neurological pathway. Additional studies are required to better understand the connection between hearing loss and impaired cognitive function such as that observed in with PTSD. Here, we use the fruit fly, Drosophila melanogaster, to explore the relationship between hearing loss and cognitive function. Negative geotaxis climbing assays and courtship behavior analysis were used to examine neurobehavioral changes induced by prolonged, intense auditory stimulation. Preliminary results suggest that exposure to loud noise for an extended period of time significantly affected Drosophila behavior, with males being more sensitive than females. Based on our results, there appears to be a potential connection between noise exposure and behavior, further suggesting that Drosophila could be an effective model to study the link between hearing loss and PTSD.

Socioeconomic differences have driven society and laid the foundation for the types of opportunities and resources one is eligible to receive. Higher socioeconomic status provides individuals the chance of obtaining an overall better education, occupation, and income. We see this with particular clarity when we examine healthcare. The World Health Organization has regarded healthcare as a fundamental human right, except socioeconomically disadvantaged individuals not only do not have equal access to healthcare, but they also often receive a lower quality of care. These socioeconomic differences are often paired with racial differences, resulting in one group, or set of groups, having social advantage over the others. Although this problem has been discussed throughout the past century, it has not been properly addressed materially and practically. Unequal access to quality healthcare is especially highlighted throughout the COVID-19 pandemic, where there has been evidence that minorities, in particular Black communities, have received inadequate care. Quality healthcare has become unaffordable and a luxury that only certain groups get the privilege of receiving. Not only that, but the ongoing inequalities in the healthcare system have gone so far that they have instilled hostility and mistrust towards the healthcare system.

In this experiment, the viability of gunshot residue (GSR) was examined. This was done through the very rarely researched intersection of forensic firearms analysis and forensic entomology. The question being resolved is if GSR can reliably be detected from secondary evidence transfer of GSR laden carrion onto flies and their larvae. While it is know that secondary and tertiary GSR evidence can be transferred by way of handshakes, no such research has been conducted on flies or their pupae. Findings indicated varying levels of detection of GSR on evidence. GSR could reliably be detected on fly bodies and their legs, but not on their pupae. This research is significant as it provides previously unknown information on this line of research and provides the groundwork for further research on this topic in the future.

A primary need of Forensic science is to individualize missing persons that cannot be identified after death. With the use of advanced technology, Radio Frequency Identification (RFID) implant chips can drastically improve digital tracking and enable robust biological and legal identification. In this paper, I will discuss applications between different microchip technologies and indicate reasons why the RFID chip is more useful for forensic science. My results state that an RFID chip is significantly more capable of integrating a mass volume of background information, and can utilize implanted individuals’ DNA profiles to decrease the missing persons database backlogs. Since today’s society uses a lot of digital devices that can ultimately identify people by simple posts or geolocation, Forensic Science can harness that data as an advantage to help serve justice for the public in giving loved ones closure.

As technological advancement increases and becomes more accessible to everyone around the world, many communities and support groups have begun to offer online options for their programs, whether it be a fitness program, online therapy group, or doctor’s appointment. With the COVID-19 pandemic affecting every country around the world, online and virtual communities have become more necessary than ever. Using personal experience from an online fitness community formed as a response to social isolation called“Barrett Healthy Minds, Healthy Bodies,” research was conducted to determine if online communities had the same effectiveness as in-person communities in reaching and maintaining individual health goals. Peer-reviewed scientific articles and research papers from many countries around the world were analyzed for demonstration and quantification of the efficacy of other online communities compared to in- person groups. In addition, the benefits and limitations of online communities were identified. Using all of the research and data collected, a novel fitness program was designed for implementation with an online synchronous group (OSG) and an online asynchronous option serving as a control to observe any differential adherence of participants to fitness goals. The proposed OSG consists of meetings and workouts through Zoom and is more interactive, even virtually. The control group had no interaction with others and completed the workouts alone. While this program was not distributed to the public and tested as part of this project, it was designed to be an optimized pilot program to test the impact of remote community engagement on goal attainment. It is predicted that the OSG would demonstrate improvement over control in better reaching goals and increased satisfaction with results. Scientific literature from a variety of disciplines discussed here informs this prediction.

While people are scrolling through their various social media apps, they encounter messaging that does not necessarily promote good mental health. Rather, images, posts, and videos often make a mockery of those with mental health problems, leaving the viewers to believe that mental health problems often lead to dangerousness, criminality, and unpredictability. It then is essential that social media messaging about mental health, and its stigmas are analyzed and solutions to promote better mental health messages on these platforms are implemented because they affect everyone. Anti-stigma campaigns may be useful in bringing awareness to mental health and its stigmas, so two anti-stigma campaigns, Stamp Out Stigma and StigmaFree, were analyzed in this study. To understand the types of messages people are receiving about mental health and its stigmas from anti-stigma organizations on social media platforms, three research questions were developed. A thematic analysis was conducted that included 205 posts from 2021 that came from the campaigns' Facebook and Twitter accounts. Several themes emerged for each research question as well as multiple limitations for this study. Ultimately, social media messaging about mental health and its stigmas must continue to be researched.

Managing plastic waste is a challenge for a small island nation like American Samoa. As a result, they need access to alternative products that will benefit their environment. The alternative products must also be equally cost-effective for local restaurants in order for them to be a viable option. The study concluded that Polylactic Acid (PLA) was the best material for take-out containers, paper was the best for cups, and wood was the best for utensils. Future research should focus on any other alternatives that become available for shipment to American Samoa, effects caused by an increase in cornstarch-based products (i.e., PLA take-out containers), and the satisfaction of both the restaurants and their customers based on the recommendations provided in this study.
