Internet search engines allow people to access new information in seconds. Although the Internet provides easy access to a mass of information, over-reliance on it changes how human memory works, which may have an adverse effect on critical thinking. Individuals with a dependence on search engines tend to remember where they found the information rather than the material itself. Human memory systems work by connecting new information to old in the brain, which requires people to actively think a...
Glass cullet (recycled or broken glass) has been proposed to replace dredged sediment in beach and river recovery processes after severe weather events. Dredging of the ocean floor to replace lost sediment on beaches has led to many negative environmental impacts, such as disturbance of marine ecosystems, notably the death of both animal and plant life near coastlines. The majority of cullet that has been proposed for replacement of dredged sediment is float glass, not bottle glass that could be...
In this paper, model-based testing strategies are described for the validation of an Adaptive Cruise Control (ACC) algorithm developed for a 2019 Chevrolet Blazer as part of the EcoCAR Mobility Challenge. A team of undergraduate and graduate students developed testing procedures to assess model fidelity, and to identify and resolve issues with the algorithm before deployment to a student-modified production vehicle. The algorithm validation is conducted via three progressive levels of validation...
The amygdala is important for the perception and expression of emotion. Research on the amygdala has shown that its activation through emotional arousal leads to enhanced memory of certain events. Emotional experience is known to induce the release of hormones epinephrine and cortisol, which are essential for responding to stressful events. These hormones initiate pathways between the amygdala, locus coeruleus and vagus nerve as well as aid in the activation of the hippocampus, a brain region in...
The UN Refugee Agency, the UNHCR, has stated that climate change will disproportionally impact the displaced as it becomes more unpredictable, intense, frequent, and dangerous (Gaynor, 2020). The UNHCR reported that in 2019, weather-related hazards resulted in almost 25 million displacements in 140 countries. This paper will examine the effects of climate change and ensuing conflict on refugees in the Sahel Region of Africa. This paper will first look at the effects from a social-ecological syst...
The efficient market hypothesis theory states that stock prices completely reflect all available information, but it does not tell us about the change in information that leads to change in stock prices. In order to find the magnitude, four regressions were carried out. Their results were statistically not significant and conveyed that the efficient market hypothesis is right.
In this work, over 400 middle school and high school students were presented science activities pertaining to authentic astronomical research. Created by a group of student research interns, these activities were delivered to classroom educators to share with their own students in person or via online instruction. This delivery took place via a series of professional development sessions delivered to teachers by the student interns, reaching a total of fifteen schools from across the United Stat...
Ponds in rural ecosystems may provide valuable habitat for a variety of cosmopolitan species, including those that are either fully aquatic or pond associated species in riparian habitats of mixed agricultural/wooded areas. We assessed the diversity of three rural ponds on private property (Southern 8’s Farm; Chesterfield, South Carolina), with different management histories using rapid species assessments. Surveys included aquatic dip-netting, sweep netting, acoustic surveys, camera trapping, a...
For so long, game developers have had to hand place waypoints, leading to linear paths being taken by Artificial Intelligence (AI) which move between them. These paths often loop, and if they don’t, they only serve to move an AI from point A to point B in the same way time and time again. A more dynamic solution is needed, and the Wave Function Collapse Algorithm is suited to provide that. This solution was implemented in the Unity engine using C#. By utilizing the provided Wave Function Collaps...
In looking at social work’s response to the human rights of refugees, the profession has not been historically very engaged with the social issue and there seems to have been a general lack of awareness regarding the human rights issues facing refugees (Libal & Popescu, 2018). However, by viewing social work as a human rights profession, social workers may have the opportunity to become more prepared to aid refugees globally not only in a clinical response, but also on the level of advocacy ...
