Description
Leadership, as a field of study, has suffered under the dialectic between an ephemerality which keeps the true nature of leadership difficult to quantify and an ardent desire to have leadership fully understood so that societal institutions may improve. It is the primary focus of this research to view leadership as the collection of skills that an individual develops over time which allows them to demonstrate leadership ability regardless of their actual position within an organization. Through a review of the leadership skills literature, a potentially unifying framework for understanding and measuring leadership skills was extrapolated: Mumford, Campion, and Morgeson’s Leadership Skills STRATAPLEX (2007). In order to determine the ability of the framework to serve as a unified model between the divergent characteristics of the public and private sectors, a limited replication study was performed on a targeted sample of Human Resources (HR) leaders in the public and private sectors. The study consisted of a twenty-three-question survey which captured the HR leaders’ years of experience, sector type (sector of employment), and their self-rated measurement of the twenty-one leadership skills needed to perform in their position. Through the limited replication study, it was found that there existed no statistically significant difference between the sector type and any of the twenty-one leadership skills within this replication study. Although it should be noted that some of the leadership skills did approach statistical significance, a more robust replication of the STRATAPLEX for the explicit purpose of determining a relationship between sector type and the twenty-one leadership skills would prove useful in determining the veracity of these results. The results of this study serve to doubly inform leadership researchers of the possibility of creating a unified leadership skills framework as well as demonstrating to organizational leaders the value in producing leadership training which models this framework as its foundation for all leadership positions.

Description
This short documentary on the Equal Rights Amendment features attorney Dianne Post and State Representative Jennifer Jermaine, and it examines the fight for passage at the federal and state level. This film attempts to answer the following questions: What is the ERA? What is its history? Why do we need it? How do we get it into the Constitution of the United States of America?
The text of the Equal Rights Amendment (ERA) states that “equality of rights under the law shall not be denied or abridged by the United States or by any state on account of sex.” The amendment was authored by Alice Paul and was first introduced into Congress in 1923. The ERA did not make much progress until 1970, when Representative Martha Griffiths from Michigan filed a discharge petition demanding that the ERA move out of the judiciary committee to be heard by the full United States House of Representatives. The House passed it and it went on to the Senate, where it was approved and sent to the states for ratification. By 1977, 35 states had voted to ratify the ERA, but it did not reach the 38 states-threshold required for ratification before the 1982 deadline set by Congress. More recently, Nevada ratified the ERA in March 2017, and Illinois followed suit in May 2018. On January 27th, 2020, Virginia finalized its ratification, making it the 38th state to ratify the Equal Rights Amendment.
Supporters of the ERA argue that we have reached the required goal of approval by 38 states. However, opponents may have at least two legal arguments to challenge this claim by ERA advocates. First, the deadline to ratify was 1982. Second, five states have voted to rescind their ratification since their initial approval. These political and legal challenges must be addressed and resolved before the ERA can be considered part of the United States Constitution. Nevertheless, ERA advocates continue to pursue certification. There are complicated questions to untangle here, to be sure, but by listening to a variety of perspectives and critically examining the historical and legal context, it may be possible to find some answers. Indeed, Arizona, which has yet to ratify the ERA, could play a vital role in the on-going fight for the ERA.

Description
Terrestrial crude oil spills compromise a soil’s ability to provide ecosystem services by inhibiting plant life and threatening groundwater integrity. Ozone gas, a powerful oxidant, shows promise to aid in soil recovery by degrading petroleum hydrocarbons into more bioavailable and biodegradable chemicals. However, previous research has shown that ozone can change the soil pH and create harmful organic compounds.
The research objective was to determine the short-term ecological toxicity of ozonation byproducts on seed germination of three distinct plant types (radish, lettuce, and grass) compared to untreated and uncontaminated soils. We hypothesize that the reduction of heavy hydrocarbon contamination in soil by ozone application will provide more suitable habitat for the germinating seeds. The effect of ozone treatment on seed germination and seedling quality was measured using ASTM standards for early seedling growth in conjunction with a gradient of potting soil amendments. Ozonation parameters were measured using established methods and include total petroleum hydrocarbons (TPH), dissolved organic carbon (DOC), and pH.
This study demonstrated the TPH levels fall up to 22% with ozonation, suggesting TPH removal is related to the amount of ozone delivered as opposed to the type of crude oil present. The DOC values increase comparably across crude oil types as the ozonation dose increases (from a background level of 0.25 g to 6.2 g/kg dry soil at the highest ozone level), suggesting that DOC production is directly related to the amount of ozone, not crude oil type. While ozonation reduced the mass of heavy hydrocarbons in the soil, it increased the amount of ozonation byproducts in the soil. For the three types of seeds used in the study, these changes in concentrations of TPH and DOC affected the species differently; however, no seed type showed improved germination after ozone treatment. Thus, ozone treatment by itself had a negative impact on germination potential.
Future research should focus on the effects of post-ozonation, long-term bioremediation on eco-toxicity. By helping define the eco-toxicity of ozonation techniques, this research can improve upon previously established ozone techniques for petroleum remediation and provide economic and environmental benefits when used for soil treatment.

Description
Photocurable nanocomposites have great potential within advanced manufacturing, multifunctional materials, and most specifically tissue engineering. The properties and characteristics of these nanocomposites can be tailored to mimic those of various tissues and/or cartilage, allowing the bio-inspired synthetic materials to replace them. This project investigates the effect of methacrylate-functionalized (MA-SiO2) and vinyl-functionalized (V-SiO2) silica nanoparticle loading content on the thermal, mechanical, physical, and morphological characteristics of PEG nanocomposites. It was discovered that both V-SiO2 and MA-SiO2 did not considerably impact the glass-transition temperature or hydrophilicity of the material. The gel fraction of composites containing V-SiO2 decreases with the initial addition of 3.8 wt%, but then displays an increase with further addition (>7.4 wt%) until it reaches a plateau at 10.7 wt%. Whereas, the MA-SiO2 induced no significant changes in gel fraction with increased loading. An increase in mechanical properties was also observed with increasing concentration for both sets of series. However, due to the higher crosslink density, MA-SiO2 reached its ultimate mechanical stress threshold at a lower concentration of 7.4 wt%, while V-SiO2 maxed out at 10.7 wt%. Scanning electron microscopy coupled with transmission electron microscopy revealed that V-SiO2 displayed a bimodal size distribution, while MA-SiO2 displayed only one.

Description
With cancer rates increasing and affecting more people every year, I felt it was important to educate the younger generation about the potential factors that could put them at risk of receiving a cancer diagnosis later in life. I thought that this was important to do because most students, especially in rural communities, are not taught the factors that increase your risk of getting cancer in the future. This leads to students not having the tools to think about the repercussions that their actions can have in their distant future in regard to their risk of getting cancer. I went to six schools throughout the valley and the White Mountains of Arizona with differing education levels and demographics to provide them with prevention strategies that they could implement into their daily lives to reduce their risk of getting cancer in the future. Some of the schools had curriculums that included cancer and some of the factors that increase your risk, while others never mention what is happening biologically when a person has cancer. I introduced factors such as no smoking or tobacco use, diet, exercise, sunscreen use, avoiding alcohol, and getting screened regularly. While at each school, I discussed the importance of creating these healthy habits while they are young because cancer is a disease that comes from the accumulation of mutations that can begin occurring in their bodies even now. After my presentation, 98.6% of the 305 students who viewed my presentation felt like they had learned something from the presentation and were almost all willing to implement at least one of the changes into their daily lives.

Description
Cerebral lateralization describes the asymmetries between the two halves of the brain which results in side-specialized processing of certain functions. This phenomenon provides a selective advantage by promoting enhanced cognitive abilities. However, due to the plastic nature of lateralization, an individual’s lateralization is highly subject to change by many external factors, such as pollution, throughout its life. Additionally, lateralized regions are dependent on different contexts, so lateralized elements do not all experience the same effects. A common pollutant found worldwide is bisphenol-A (BPA), a critical component of many plastics. BPA is a known endocrine disruptor that can agonize and antagonize the functions of sex steroids. Other studies have demonstrated the importance of sex steroids in regulating the development of cerebral lateralization; BPA may similarly affect lateralization. A popular research animal for studying toxicology is the zebrafish. Its advantages include a fully sequenced genome, many human orthologs, and more importantly, expresses lateralized behaviors that are indicative of the strength of its cerebral lateralization. This experiment analyzed the effects of BPA exposure on visual lateralization of zebrafish. Given the role that sex steroids play in moderating lateralization, it was hypothesized that exposing zebrafish to BPA would diminish the strength of lateralization in the brain which would translate into reduced behavioral lateralization. To test this, one group was exposed to 0.01 mg/L BPA for one week and compared against a control group in their eye preference when approaching a visual cue. Two settings, a foraging context and a social context, were utilized to examine the scope of impairment in lateralization. The control group in both settings displayed similar strengths in behavioral lateralization with a left eye preference. However, the lateralized response faded completely with BPA treatment. This experiment demonstrates that BPA induces loss of lateralization and possesses similar impacts on mechanisms controlling investigatory behavior in these two contexts. Wild populations may encounter higher concentrations of BPA, and although there is greater variability in these exposures, this experiment proves that exposure even beyond critical periods of development can impair lateralization. Additional research will have to be conducted to identify the effects of BPA on other lateralized behaviors and sensory modalities to pinpoint the exact mechanisms through which BPA influences lateralization.

This paper intends to parse out the differences between various types of nationalism. It will break down the current trend toward xenophobic rhetoric in modern democratic election campaigns. Then, it will discuss the effect of modern media coverage in the dissemination and sustenance of toxic nationalist rhetoric and cover the role of President Donald J. Trump in doing the same. Finally, it will outline what appears to be the root cause of this current uptick in toxic nationalism and recommend some methods by which the issue can be resolved in the current political atmosphere.

Description
This paper investigates whether incarceration has an effect on political orientation, addressing the hypothesis that the experience of incarceration also shapes the political behavior and attitudes of those who have been confined (Manza, Uggen 2006; Clear 2007; Travis 2005). The primary aim of the research is to identify what role, if at all, the penal system plays in how incarcerated individuals think about politics. The data relied on to reach conclusions about the incarcerated population derives from voluntary responses to a survey implemented within a company that hires formerly and currently incarcerated persons. I find that the majority of the sample I surveyed became more politically liberal as a result of incarceration and a vast majority want to participate in the political process. These findings corroborate my hypotheses regarding the effects of incarceration on political beliefs, but contradict my assumption regarding the effect of social capital on their desire to participate in politics.

Description
This study examines the impact of international youth exchange on past participants’ global engagement through the lens of their academic, professional, and personal development post-exchange. Through a quantitative survey, as well as interviews conducted with alumni, this research explores the ways in which international exchange alumni felt as though their exchange impacted - or did not impact - their future academic, career, and personal choices. Furthermore, this study investigates the dynamics and practices of the specific organization of study, Tempe Sister Cities, and provides information regarding strengths and areas for improvement based upon feedback from study participants. This research builds upon existing literature on international exchange outcomes through its long-term perspective and evaluation of a Sister Cities affiliate, which is an organization previously omitted from international exchange impact evaluations. The study finds that while international exchange experiences may not contribute to overt, direct influences on the fields and industries in which alumni choose to study and work, the exchange produces long-lasting impacts through the skills alumni acquire in intellectual curiosity, job readiness, and other areas of personal and professional development.

Description
Personality is a relevant and applicable research topic now more than ever; because of the Internet, self-report measures of personality are becoming increasingly accessible. Although now widely available for personal application, personality inventories are not often examined in the context of their associations with other factors. Specifically, there exists a gap in the research on personality and its associations with philosophical belief. Based on a sample of 88 individuals, correlations between the Big Five and Philosophy Dichotomy Test were examined in order to investigate the associations between personality traits and philosophical belief. Agreeableness was found to be negatively associated with the sensuality, values, metaphysical, and societal axes, corresponding to higher levels of hedonism, rationalism, materialism, and egoism. These findings suggest that personality as measured by the Big Five and philosophical belief are somewhat associated. Limitations and future directions are presented.
