    No full text
    abstract: During the global COVID-19 pandemic in 2020, many universities shifted their focus to hosting classes and events online for their student population in order to keep them engaged. The present study investigated whether an association exists between student engagement (an individual’s engagement with class and campus) and resilience. A single-shot survey was administered to 200 participants currently enrolled as undergraduate students at Arizona State University. A multiple regression analysis and Pearson correlations were calculated. A moderate, significant correlation was found between student engagement (total score) and resilience. A significant correlation was found between cognitive engagement (student’s approach and understanding of his learning) and resilience and between valuing and resilience. Contrary to expectations, participation was not associated with resilience. Potential explanations for these results were explored and practical applications for the university were discussed.

    abstract: There does not appear to be a singular variable that determines where companies choose to place their distribution centers, however there are several underlying factors that may alter companies’ decisions on what countries they develop distribution networks in. There are many reasons companies choose a distribution centers’ location: infrastructure, trade barriers, and costs are often considered as well as the supply and demand markets for the product offerings. Countries can alter aspects to increase the number of businesses that operate within their bounds. When a distribution center is constructed local communities benefit from corporate initiatives and funding as well as jobs and access to cheaper products. Countries often utilize taxes and regulation to positively impact the environment when introducing distribution centers to their economy. The goal is to understand the weights of different factors that shape where distribution centers are located and inform decision makers on the aspects they should alter to get the greatest return on investment. The resulting data will display how large retailers have positioned their current warehouse to indicate likely expansions and the factors that are currently affecting location decisions. The research project asks the following questions: When determining the best location for distribution centers, what factors have the largest impact on business decisions? What role do governments play in developing space for companies to conduct business in (how do they update their infrastructure and customs methods including the impact on trade across industries)? How can governments and the community limit outsourcing and/or bring businesses (and thus distribution centers) closer to home? When determining distribution center locations, most companies analyze the political and market structure to decide whether they will enter the market. Once companies have chosen the general region they are hoping to gain, infrastructure and costs are analyzed to find to maintain a competitive advantage in cost while maintaining relatively close locations to stores and consumers. Many companies utilize intermodal transportation on a macroscale, however in last mile logistics it is uncommon for large retailers such as Amazon and Walmart to use anything other than trucks (most commonly their own fleet). Governments have a clear role in gaining or limiting business, however, these factors are typically only considered upon entry or due to changes in major trade barriers therefore policy changes are less likely to encourage growth than investments in infrastructure or alterations in economic conditions such as taxes. Consumers and governments should work together to create an environment that fosters business growth in both new companies entering the market and existing companies expanding by creating unique policies that utilize taxes and business investments to invest in infrastructure.

    Protection Against Basal Cell Carcinoma: Limitations in Sunscreen, Further Research, and Recommendations

    No full text
    abstract: Skin cancer diagnoses and deaths continue to increase every year. With basal cell carcinoma (BCC) being the most common type of skin cancer diagnoses, establishing protective measurements against it are important. Surprisingly, sunscreen may not be as effective at protecting against basal cell carcinoma as it is for another non-melanoma type of skin cancer: squamous cell carcinoma. This paper aims to identify some differences between the two non-melanoma type cancers to find probable reasons sunscreen may be more effective at protecting against one over the other, as well as to find new solutions to protect against basal cell carcinoma. The results conclude that basal cell carcinoma does have UV-induced pathogenesis, in which case sunscreen is protective; however, it also revealed the need for ingredient studies and more sunscreen efficacy studies to determine other BCC pathogenesis pathways. Lastly, aided by dermatologist interviews, current interventions were established in order to provide greater protection against skin cancer. These include reforming the way commercials portray sunscreen to better educate the public about proper application and re-application, genetic testing for high-risk BCC markers, and an emphasis on sun education to the mothers of children.

    Analysis of Student Stress Before and During COVID-19

    No full text
    abstract: The mental health of ASU students has been negatively affected by the pandemic. Our research looks to prove that COVID-19 has caused an increase in stress levels while uncovering other relationships to stress. We obtained our data by conducting a survey through Google Forms that was exclusively accessible to ASU students. Stress levels were measured with the use of the Perceived Stress Scale (PSS). We find that the stress of ASU students from before the pandemic to during rises from 15 to 22 points, a 50% increase (n = 228). We discovered that women are more stressed than men before and during the pandemic. We also discovered that there is no difference between stresses among different races. We notice that there is a parabolic relationship between enrollment time and stress levels with the peak occurring during semesters 2-6. We also conclude that students who attended more than 5 events during the pandemic had lower stress scores, and those who had their videos on for at least 3 events had lower stress scores. Furthermore, students who utilized campus resources to manage their stress had higher stress levels than those who did not. (abstract

    Comparing Police Use of Force Policies to Scholarly Recommendations

    No full text
    abstract: Police use of force is a controversial practice on both the political stage and by scholars of criminal justice. Scholarly research has highlighted best practice for police departments’ use of force policies. Diverging from these policies may produce ineffective and harmful use of force practices within departments. Because of these potential consequences of police departments diverging from research-based evidence, it is necessary to identify when recommended policy is not being utilized. The purpose of this study is to identify whether there are points of dissent or congruence between criminal justice scholars and police departments with regards to use of force policy. Efforts have been made to empirically identify best practices of use of force policy. The findings of this study indicate that points of dissent do exist in the policies of police departments in the U.S. and the policy recommendations of criminal justice scholars. The implications of these findings include reform to the use of force policies of police departments to more accurately reflect the policies recommended by scholars in the use of force. (abstract

    The Psychological Classification of Dogs: A Literature Review of Personality Testing in Dogs

    No full text
    abstract: Personality testing in dogs has become a controversial topic in the dog community in the last few years. These assessments have been used among owners, shelters, working dog trainers, breeders, and researchers to identify patterns of behavior that may lead to insight about a dog’s personality. Due to inconsistencies in terminology and validity testing, these personality tests have lost a notable amount of credibility. Focusing on questionnaire and behavioral based testing, this literature review aims to evaluate the significance of personality testing within the dog community. Each assessment will be analyzed for measurements and validity, as well as potential drawbacks and benefits. Four prominent personality assessments will be discussed in depth. These assessments include C-BARQ, DPQ, SAFER, and VIDOPET. I advocate for a mixed assessment model approach and highlight the benefits of expanding personality testing into genetic research.

    Meson Decay in e p → e p K+ K- and e p → e p K+ K- π0 events

    abstract: In the quark model, meson states consisting of a quark/anti-quark pair must obey Poincaré symmetry. As a result of that symmetry, for meson total angular momentum J, parity P, and charge conjugation symmetry C, states with JPC= 0--, 0+-, 1-+, 2+-, 3-+, 4+-, … should not be observed. A meson observed experimentally with such quantum numbers would indicate a so-called “exotic� meson state. Exotic mesons can be multi-quark states like tetraquarks, a combination of two or more gluons known as glueballs, or a hybrid meson (qqg). Theories have suggested that three possible exotic meson states with the 1-+ quantum number: π1, η1, and η‘1,. However, no conclusive evidence for the existence of these three exotic states has been observed. This research will look for new states that decay to K* K final states with an emphasis on exotic mesons. An analysis of K+ K- π0 final states will be presented, where a restriction on the K - π0 invariant mass yields an unexpected enhancement in the K+ K- π0 spectrum. (abstract

    abstract: 2D fetal echocardiography (ECHO) can be used for monitoring heart development in utero. This study’s purpose is to empirically model normal fetal heart growth and function changes during development by ECHO and compare these to fetuses diagnosed with and without cardiomyopathy with diabetic mothers. There are existing mathematical models describing fetal heart development but they warrant revalidation and adjustment. 377 normal fetuses with healthy mothers, 98 normal fetuses with diabetic mothers, and 37 fetuses with cardiomyopathy and diabetic mothers had their cardiac structural dimensions, cardiothoracic ratio, valve flow velocities, and heart rates measured by fetal ECHO in a retrospective chart review. Cardiac features were fitted to linear functions, with respect to gestational age, femur length, head circumference, and biparietal diameter and z-scores were created to model normal fetal growth for all parameters. These z-scores were used to assess what metrics had no difference in means between the normal fetuses of both healthy and diabetic mothers but differed from those diagnosed with cardiomyopathy. It was found that functional metrics like mitral and tricuspid E wave and pulmonary velocity could be important predictors for cardiomyopathy when fitted by gestational age, femur length, head circumference, and biparietal diameter. Additionally, aortic and tricuspid annulus diameters when fitted to estimated gestational age showed potential to be predictors for fetal cardiomyopathy. While the metrics overlapped over their full range, combining them together may have the potential for predicting cardiomyopathy in utero. Future directions of this study will explore creating a classifier model that can predict cardiomyopathy using the metrics assessed in this study. (abstract
