Humans use emotions to communicate social cues to our peers on a daily basis. Are we able to identify context from facial expressions and match them to specific scenarios? This experiment found that people can effectively distinguish negative and positive emotions from each other from a short description. However, further research is needed to find out whether humans can learn to perceive emotions only from contextual explanations.
Visual presentation of information is one method of learning that has the ability to enhance STEM learning compared to learning solely through text. Educational psychology research is ongoing in the STEM field for how students can learn better through visual representations in their course material. The goal of this study was to assess student responses to visual mini-lessons related to course content in the cardiovascular unit in Animal Physiology (BIO360) at Arizona State University. Study participants completed a series of eight mini-lessons and a survey on their experience with the visual lessons. The results of the survey identify increased desire for visual learning materials in STEM courses. The study participants reported that they felt more visual aids in their STEM courses would increase their understanding of course content and that their classroom performance would improve.
This thesis investigates the transmission of Covid-19 from humans to animals. Within the article, one will learn the inner workings of the background, history, and transmission of the SARS-CoV-2 infection seen worldwide. In addition, the research proposal/study focuses on the transmission of SARS-CoV-2 observed from humans to minks.
Eel Farming: A Theoretical Research Design on Improving the Success of Eel Reproduction in Captivity
This thesis’s goal was to design a theoretical research study based on a literature review on improving the aquaculture of European eels. Aquaculture is the farming of aquatic species such as fish. The European eel is a critically endangered catadromous fish species that faces a continuous decline in wild populations over the years due to pollution, climate change, industrial development, and overfishing. The replenishing of the fishery stock of European eels relies heavily on the wild population since there is no sustainable way of creating a generational captive population. The reason for this is that the lifecycle and environmental triggers of freshwater eels are relatively unknown due to their long lifespan, migratory lifestyle, metamorphoses, and sex differentiation timing. The primary focus of the design was to use different hormonal regiments and compared their effects on hatch rate, clutch size, survival rate, and lifespan of the juvenile eels. From this, it was concluded that the mother eel’s lipid storage impacts the quality of yolk sacs which in turn impacts the survival of leptocephali (eel larvae). The primary focus on eel population recovery should be habitat restoration and research on the leptocephalus stage since they both have the most evidence of success in eel population recovery.
As the pandemic hit back in 2019, an influx of pet adoptions occurred as more people were spending time home alone and saw the need for a companion. While SARS-CoV-2 is still circulating the globe, and mutating into different strains, people are continuing to work from home close to their animals. Evidence has shown that animals like dogs, cats, minks, and ferrets can contract the disease from their human counterparts, however, it is unclear if humans can contract the disease back from their animal companions [6]. While we have seen these Coronavirus outbreaks continually occur in the past several decades, we must be properly knowledgeable on the transmission capabilities of the virus to combat another wave of a SARS outbreak for future decades to come. Earlier coronavirus’ present in veterinary medicine has been noted to progress into more fatal and aggressive diseases when transmitted from one species to another [7], and therefore it is just as important that we understand the transmission possibilities of the virus in animals as we do ourselves. To determine if our pets can transmit the virus to us humans, a study is proposed where canines are purposefully inoculated with a selected SARS-Cov-2 virus and exposed to human volunteers to determine if the virus can spill back from canines to humans. To determine which virus strain will be utilized for the study, data regarding potential strain hosts will be collected from directly ill volunteers who also own canines prior to inoculation.
Patients need to know current and available options for prosthetic devices. Devices are categorized depending on the region of amputation and their purpose. Retrospection on the history of prosthetic devices leading into modern ones allows for an interpretation of successes and necessary improvements moving forward. One promising avenue for prostheses is the development of neuroprostheses that much more closely resemble some of the functionality taken for granted in natural limbs. Proprioception, more commonly known as the ‘sixth sense’, would be a very desirable characteristic of these devices and is the subject of current research efforts. In the meantime, it is necessary to help patients evaluate what products are out there that identify more strongly with their individualized preferences.
