    ActionPoint: Bringing Together Computer Science and Psychology to Design an App to Prevent Cyberbullying

    No full text
    abstract: Over the past several decades, cyberbullying has increasingly become one of the most dangerous threats to an adolescent’s mental health. Heather Springer, writing for the American Psychological Association, projects that roughly 33% of American teenagers are affected by cyberbullying while on social media (Springer). This startling percentage, compounded by an escalating need to combat cyberbullying’s negative impact on mental health, has catalyzed a wave of psychological research to explore the ways in which social media impacts teens. Over the years, researchers have produced a plethora of publications on the subject, inspiring families to pursue cyberbullying prevention for their loved ones. However, despite this surge in anti-cyberbullying interest, few researchers have attempted to coalesce these psychological findings with computer applications, and fewer still have sought to prevent cyberbullying through the strengthening of parent-teen relationships (Silva et al., 2019). Because of this, the BullyBlocker team, led by Dr. Yasin Silva and Dr. Deborah Hall, has spent the past couple years developing a mobile application called ActionPoint. Our team hopes that through this app, the risk of cyberbullying is drastically decreased and even prevented. (abstract

    Circular DNA viruses identified in short-finned pilot whale and orca tissue samples

    abstract: Members of the Delphinidae family are widely distributed across the world’s oceans. We used a viral metagenomic approach to identify viruses in orca (Orcinus orca) and short-finned pilot whale (Globicephala macrorhynchus) muscle, kidney, and liver samples from deceased animals. From orca tissue samples (muscle, kidney, and liver), we identified a novel polyomavirus (Polyomaviridae), three cressdnaviruses, and two genomoviruses (Genomoviridae). In the short-finned pilot whale we were able to identify one genomovirus in a kidney sample. The presence of unclassified cressdnavirus within two samples (muscle and kidney) of the same animal supports the possibility these viruses might be widespread within the animal. The orca polyomavirus identified here is the first of its species and is not closely related to the only other dolphin polyomavirus previously discovered. The identification and verification of these viruses expands the current knowledge of viruses that are associated with the Delphinidae family. (abstract

    Food Waste Fertilizer Efficacy

    abstract: As the world’s population exponentially grows, more food production is required. This increasing food production currently has led to the un-sustainable production of chemical fertilizers and resultant overuse. A more sustainable option to enhance food production could be the use of fertilizer derived from food waste. To address this, we investigated the possibility of utilizing a fertilizer derived from food waste to grow hydroponic vegetables. Arugula (Eruca sativa) ‘Slow Bolt’ and lettuce (Lactuca sativa) ‘Cherokee’ and ‘Rex’ were cultivated using indoor deep-flow hydroponic systems at 23 ºC under a photosynthetic photon flux density of 170 µmol∙m−2∙s−1 with an 18-hour photoperiod. Plant nutrient solutions were provided by food waste fertilizer or commercial 15:5:20 NPK fertilizer at the identical electrical conductivity (EC) of 2.3 mS·cm–1. At the EC of 2.3 mS·cm–1, chemical fertilizer contained 150 ppm N, 50 ppm P, and 200 ppm K, while food waste fertilizer had 60 ppm N, 26 ppm P, and 119 ppm K. Four weeks after the nutrient treatments were implemented, compared to plants grown with chemical fertilizer, lettuce ‘Rex’ grown with food waste fertilizer had four less leaves, 27.1% shorter leaves, 68.2% and 23.1% less shoot and root fresh weight, respectively. Lettuce ‘Cherokee’ and arugula grown with food waste fertilizer followed a similar trend with fresh shoot weights that were 80.1% and 95.6% less compared to the chemical fertilizer, respectively. In general, the magnitude of reduction in the plant growth was greatest in arugula. These results suggest that both fertilizers were able to successfully grow lettuce and arugula, although the reduced plant growth with the food waste fertilizer in our study is likely from a lower concentration of nutrients when we considered EC as an indicator of nutrient concentration equivalency of the two fertilizer types.

    Working to Deliver in Virtual Teams: An Analysis of Communication and Management Strategies through Interviews and a Simulation

    No full text
    abstract: To understand the role communication and effective management play in the project management field, virtual work was analyzed in two phases. Phase one consisted of gaining familiarity within the field of project management by interviewing three project managers who discussed their field of work, how it has changed due to Covid-19, approaches to communication and virtual team management, and strategies that allow for effective project management. Phase two comprised a simulation in which 8 ASU student volunteers were put into scenarios that required completing and executing a given project. Students gained project experience through the simulation and had an opportunity to reflect on their project experience. (abstract

    Validating a New CFD Algorithm by Finding the Drag Coefficient of a Sphere

    No full text
    abstract: A novel CFD algorithm called LEAP is currently being developed by the Kasbaoui Research Group (KRG) using the Immersed Boundary Method (IBM) to describe complex geometries. To validate the algorithm, this research project focused on testing the algorithm in three dimensions by simulating a sphere placed in a moving fluid. The simulation results were compared against the experimentally derived Schiller-Naumann Correlation. Over the course of 36 trials, various spatial and temporal resolutions were tested at specific Reynolds numbers between 10 and 300. It was observed that numerical errors decreased with increasing spatial and temporal resolution. This result was expected as increased resolution should give results closer to experimental values. Having shown the accuracy and robustness of this method, KRG will continue to develop this algorithm to explore more complex geometries such as aircraft engines or human lungs. (abstract

    Salad? Pizza? Or Exam? - An Analysis of College Student Nutritional Choices
