A literature search of research and academic journals suggests that there are few critical examinations of LDS visual culture in visual culture research. The purpose of this exploratory study is to examine the types of gender roles portrayed in contemporary LDS visual culture, the visual codes used to represent these gender roles, and the degree to which the representations of gender used in LDS visual culture align with findings in related visual culture studies. The result of this study will be a description of the current visual strategies used by the LDS church to represent gender roles, a thematic analysis of these visual strategies, and suggestions for future research into the ways that the LDS church visually defines gender in relation to existing trends and themes in visual culture research. The scope will include: “Mormon Ads,” images used in the LDS magazine, “Ensign,” and conference memes used during the years 2016-2019. This will contribute to the field of visual culture and gender studies by examining the visual codes used by the LDS church to portray the role and status of males and females as represented in current LDS visual culture, determining the strategies used in these representations, and discussing the potential research implications of these findings in light of themes in visual culture gender studies. Some research questions are: What visual codes are used in the representation of males, females, and mixed-sex groups in current LDS visual culture? What types of roles and status do these visual codes convey pertaining to the representation of males, females, and mixed-sex groups in current LDS visual culture? What extent do the results of investigating the above research questions align with other research findings in gender and visual culture studies? The methods used in this research will be 1) an inventory of discrete visual codes (e.g. color use, affect/expression, clothing/dress, setting, etc.) used in the LDS visual culture samples, and 2) a separate thematic analysis of the sample will also be conducted. The results of both methods will be compared, analyzed, and discussed in light of current trends in visual culture gender research. While the results of this research are expected to demonstrate that LDS visual culture will emphasize and reinforce traditional gender roles of females as mothers and homemakers and males as leaders and providers, it is hoped that this study will reveal strategies related to gender role representation unique to LDS culture.

To those of us who are privileged enough to pad ourselves from the immediate consequences of global climate change, its reality remains an abstract and intangible problem. In the tropical cloud forests of Costa Rica, however, the effects of global warming are readily evident. My research aims to provide a narrative of climate change in the uniquely diverse and delicate cloud forest ecosystem, where I work in partnership with Ph.D. ecology student Jessica Murray. While Jessica uses sensors and datasets to quantify an intricate network of plants, animals, and microorganisms, my intent is to help non-scientists to visualize the implications of Jessica’s findings. My purpose is not to simplify or re-tell Jessica’s research, but to help the viewer connect with unfamiliar, abstract ideas in a visceral, internal way. I leverage paint, poetry, infographics, and abstraction to construct a metaphor for climate ecology: the human body. Working within this metaphor allows me to channel the viewer’s own physical, bodily experiences into an intimate portrait of ecological systems and their vulnerability to climate change. My goal is for viewers to become more conscious of their own ecology-- more aware of their dependence on the environment and more compassionate towards its components.

Narcissism in organizations is becoming increasingly prevalent, as evidenced by the growing number of CEOs that seek acclaim and dominance, often at the expense of others (Chatterjee, 2017). Narcissism is defined as "individuals for whom enhancing the positivity of the self (specifically, to achieve status and esteem) is overwhelmingly important" (Campbell, 2004), and most often wields a detrimental influence on organizations. Typically, narcissism within organizational leadership has shown to lead employees to view managers' behavior as self-serving, lowering perceptions of managerial trustworthiness and increasing the likelihood of employee silence (Hamstra, 2019). Additionally, scholars have empirically demonstrated that silence provokes specific emotions, with anger being a particularly common emotional consequence of silence (Kirrane, 2017). The main effect of narcissism seems to lie in a stronger arousal of anger (Laurenz, 2013), which in turn may energize employees to proactively change the situation (Lebel, 2016). Employees often generate awareness of specific dissatisfying aspects of work by means of prohibitive voice (Chamberlin, 2017), which emphasizes harmful, failing, or wrongful work practices or events that currently exist (Liang, 2012).
In this study, I hope to examine how a leader's narcissism could arouse anger in employees and energize them to engage in prohibitive voice. Specifically, I hypothesize that a higher level of anger derived from a narcissistic leader's actions will positively correlate to a higher frequency of employee voice.

Hypotheses:
1. Perceived managerial narcissism will relate positively to employee voice.
2. Perceived anger will mediate the relationship between managerial narcissism and employee voice.
3. Employee status will moderate the relationship between managerial narcissism and employee voice.

This study is aimed to contribute to our understanding of the correlation between leadership and employee voice. I will test these hypotheses by recruiting 200 full-time employees to complete a survey. No identifying information will be collected.

This research examines two fundamental topics of economics: accuracy of prices and the effect of market participation on individuals. In particular, it asks how security structure affects price and allocational efficiency through the equilibration process.

Security structure is defined as the payoff correlation structure between tradable assets. Economists agree that the markets they are studying are in equilibrium and also that there are equilibration forces that will drive markets towards equilibrium if they are not already there (see, for example, Arrow and Hahn (1971)). There is much less agreement, however, on what these equilibration forces are. Furthermore, it is very difficult to learn about these driving forces through the analysis of historical data because not enough is known about the fundamentals (wealth, human capital, and preferences of individuals) of past markets. This represents a great opportunity for experimental finance, where markets can be created in a laboratory setting allowing researchers to know, control, and change the fundamentals of the markets they create. This research examines what asset structures yield the most efficient allocations as a result of imposed fundamentals. The trading platform is Continuous Double Auction and is implemented in a software called Flexemarkets (flexemarkets.com). The main hypothesis is that markets consisting of securities that correlate negatively will exhibit the highest allocational efficiency. Data collection with human traders will be collected in the months of November and December. Pilot sessions with humans suggest that negatively correlated assets aid price discovery but more data is needed to address allocational efficiency.

The question regarding asset structure and its effect on financial well-being is especially relevant given the increasing popularity of index funds (see Bogle (2016)), which are typically positively correlated. Results of the experiment could yield substantial policy implications concerning what types of security designs lead to optimal allocational outcomes.

The United States is home to a vast range of diverse people, however even though there is so much diversity in society the idea of beauty is pretty still very limited. Body image issues and discrimination are especially prevalent in minority groups including the plus size community. According to G.M. Eller fat people have a harder time obtaining jobs, college education, and just making a good impression on people than skinnier people solely based on their body size. These discriminations are argued to be deeply rooted in American culture and the best way Eller suggests to combat it is through educating people on the realities of obesity and not just the often harsh, outdated judgements. This paper is a textual analysis that utilizes Muted Group Theory in relation to the 2019 motion picture, Isn't It Romantic to unpack discrimination against the plus size community. Concepts from Muted Group Theory such as assimilation, separation, and accommodation are discussed. This paper argues that the movie is a positive step forward into making the plus size community's voice fall under the accommodation concept in Muted Group Theory rather than assimilation or separation especially in relationship to the dominant group in society.

Purpose - The purpose of this presentation and paper is to explore work-life balance predictors of job satisfaction across various generations, using international sample of workers across 37 countries. The four generational cohorts included in the analysis include Silent Generation, Baby Boomers, Generation X, Millennial.

Design/methodology/approach: This study provides a comparative analysis of work-life balance indicators of overall job satisfaction across generational cohorts, utilizing data from the 2015 Work Orientations IV Wave of the International Social Survey Program (including stratified random samples of employees across 37 different countries).

Findings: Initial analyses indicate statistically significant differences in work-life balance related indicators of employee job satisfaction across generational cohorts. Additional analyses will be performed to clarify these relationships and further explore the causes behind the differences.

Originality/Value: While many studies have been performed on job satisfaction, very few studies have explicitly examined job satisfaction levels and its indicators across generations. Additionally, while many studies have examined the role of work-life balance saliency on job satisfaction across generational cohorts, and no research has previously been done examining these relationships cross-nationally.

Keywords Job satisfaction, Generational Differences, Work-life Balance, Cross-national

Purpose/Hypothesis:

We hope to supply statistical evidence that there are differences in the saliency and impacts of work-life balance variables on job satisfaction across generational cohorts. Specific hypotheses include:

H1: There are statistically significant differences in the mean scores of job satisfaction and work-life balance variables across generational cohorts.

H2: One's age (generational cohort grouping) has a positive statistically significant impact on job satisfaction.

H3: One's age cohort has a statistically significant impact on the determinants of job satisfaction.

H4: There are statistically significant cross-national differences in the impact of generational cohort on job satisfaction.

The purpose of this study is to understand how racial dissimilarity affects people of color's voice behavior in a student or class group. In a group where a person's social category is underrepresented, they become more aware of that social identity and their ability to perform at their full potential reduces because they are more focused on monitoring their performance and suppressing negative thoughts and feelings than improving group performance. However, in situations where people are more identified with the group, they are more likely to feel committed to or express themselves in a group. Additionally, in groups where people of color don't perceive themselves as different from all or most of the other group members, subgroups and division among team members is less likely to occur. In order for people of color to contribute in meaningful and innovative ways, having the confidence to speak up and express new ideas is crucial. We will run a survey where participants recall groups that they have been a part of and rank their voice (participation) in the group, their perceived racial dissimilarity of the group, and the importance of race on their personal identity. Afterwards, they will placed in an online student group chat with high or low dissimilarity and will be asked to reflect on their experiences. In line with previous research we expect that the importance of race on their personal identity will be positively related to perceived racial dissimilarity and therefore, we expect peoples' voice behaviors to decrease when they are in a group where racial dissimilarity is high.

There have been recent developments in reproductive technologies that are staking claims to better the lives of women. The invention and development of reproductive technologies alone is not enough to classify them as technologies aiding women, however. Ultrasound, IVF, and breast reduction technologies specifically can be as helpful to women as they were intended. Ultimately, the way they are put into practice, viewed by society and used by professionals can inadvertently make women feel more marginalized. A woman's agency is diminished by ultrasound technology as she is debating having an abortion; a woman's involvement in her own IVF-aided pregnancy can be positive or negative depending on the outcome; a woman's breasts can contribute to her femininity so long as they fit societal standards. As a technical communicator, I feel a responsibility to bridge this gap between technology and humanity because the two need to function together without one negatively impacting the other. Through my research I will prove this by drawing on the work of Mary Daly and her theory of a rhetorical foreground and background (spaces where women are oppressed and spaces where the oppression is removed, respectively) while analyzing the findings presented by Mary Lay Schuster in her article "The Rhetoric of Reproductive Technologies." Throughout this analysis, I would like to not only point out the problems women are currently encountering with different reproductive technologies, but also to suggest ways to amend the situation moving forward. Mary Lay Schuster points specifically in her article towards the practice of midwifery, and so one of my solutions would include utilizing modern medicine in combination with midwifery.

The purpose of this research project is to examine the interplay between psychotherapeutic mobile applications, such as Calm and Headspace, and the people that use them. Using Langdon Winner and David Nye's discussions on technologies and the discourses surrounding them, I aim to synthesize the existing literature, which primarily investigates the effectiveness of these mobile technologies as forms of psychotherapy, with the concept of technology as an identity-forming tool. I hope to address how these psychotherapeutic technologies can both enable and disallow users, and how users, through their engagement with these mobile applications, are challenging prevailing definitions of psychotherapy and technology. Through a thorough analysis of current literature, together with Winner and Nye's work and my own evaluations of public online reviews of psychotherapeutic mobile applications, I intend to advance the research that considers how technologies affect people and how people affect technologies.

The use of genetically modified organisms in the production of food products in the U.S. appears to be pervasive. For example, it is reported that 90 percent of corn, soy and other crops grown in the U.S. are currently genetically modified and 75 to 80 percent of food products contain GMOs or GMO components. Unfortunately, a gap exists between what scientists and consumers believe with regard to the health safety of GMO foods. Specifically, it has been reported that while "Nearly 9 out of 10 scientists from the American Association for the Advancement of Science say GMOs are 'generally safe' to eat, more than half of general public believe it is not a good idea." This presents a challenge for restaurants. That is, should they continue to use GMO food products given assurances from the scientific community or should they respond to consumer concerns and begin the process of adopting a non-GMO policy? The purpose of this research is to address this question by proposing a framework that helps explain why a restaurant might decide to adopt (or not adopt) a non-GMO policy. Based on an adaptation of Roger's Characteristics of an Innovation, the framework has five constructs: (1) Relative Advantage, (2) Compatibility, (3) Complexity, (4) Trialability, (5) Observability. An exploratory application of the model to U.S. restaurants suggests that the framework can provide meaningful and systematic insights into the perceptions of U.S. restaurants with regard to the adoption or non-adoption of a non-GMO policy. Recommendations for further application of the framework, along propositions for additional analysis are provided. Implications for decision making are also presented.

The TV show 30 Rock has been described as many things; laugh-out-loud funny, immature, witty... but is it feminist? The show's main character makes claims to feminism in almost every episode, and several episodes cover the topic in various ways. However, she often falls short in her feminism, and the argument can be made that this is intentional. For my presentation, I'll be analyzing the show through the rhetorical lens of Mary Daly's theory on foreground/background spaces. Spaces where women are oppressed and free of oppression, respectively; for example, in the show, the characters are creating a sketch comedy TV show, a place where women have traditionally been marginalized by mainstream media - in contrast, the writers' room is a place where they can speak their minds freely about any topic of their choosing. Through my analysis, I'll also be looking to see if this can be a space for second and third wave feminists to meet. Many third wave feminists are doing things that would be considered "traditionally feminist" without identifying themselves with the term "feminist". There are a few characters in the show who identify as such, and the main character, considered to be a traditional second wave feminist, learns to work together with them. As a result of my analysis, I want to be able to present 30 Rock and other similar spaces as a middle ground for all feminists to meet and agree on, in order to be able to move forward as a movement.

Abstract: Have you ever wondered why economists always talk about a growing economy? Modern economists today rely on several fundamental assumptions in the same way physicists rely on laws governing energy and motion. Economists use growth—ideally unrestricted growth—as the key assumption upon which we build models and policy recommendations. The central economic theory explains that growth will enhance individual well-being over time. However, every known physical system has boundaries beyond which it will collapse, and the observed reality is that economic growth cannot be separated from physical resource consumption. As a result, many societies are overshooting physical, ecological boundaries.

This project focuses on outcomes generated by a few of those complexities in a growth-oriented economy in Northern Utah. It analyzes the ways traditional economic models prioritize growth as the primary means of improving quality of life. It explores several positive and negative impacts of limits to growth, whether they are elective policy measures (like paying a carbon tax) or reactions to a collapsed system (like depleted natural gas deposits). It draws on electricity data from two electricity utility providers and compares trends with interconnected behavioral and technological changes.

Ultimately, this project develops a case study to assess ways in which society could thrive without traditional economic growth. By using axioms from physics, primarily the first and second laws of thermodynamics (energy and entropy) this project assesses population projections and increased resource consumption, drawing connections between a growing population, a growing economy, and growing energy use.

Rural communities in Utah may be an excellent place for technology companies to expand. Many rural Utah communities face major problems with declining economies. Adding to the problem, median incomes in nine rural counties is $48,306 while the statewide median income is $62,961 (US Census Bureau, 2017). Rural areas seem to be an untapped well of potential to help both the state’s economy and tech companies themselves. This research explores how to effectively use that potential.

The object of this research is to identify needs and limitations that currently exist in rural communities that would prevent or could be seen as obstacles for technology industry to grow in these areas. Ongoing research being conducted is looking into the viability of technology companies being able to expand and/or start up in rural Utah by exploring if those areas are ready for the technology industry. Specifically, the research examines:

1. Current educational opportunities related to technology in rural area school systems.

2. Interest among potential workforce in technological fields.

3. Presence of skilled workforce in these rural areas.

4. Potential to form partnerships between higher education and high schools to offer better education and generate interest.

5. Infrastructure of rural areas to support growing technology industry.

Additionally, obstacles that are preventing these areas from being able to support technology industry are found and examined. This research constitutes the first step in helping bolster rural economies through an increase of jobs and industry into those areas. By conducting extensive research and getting in on the “front-lines” of the problem, current situations are more understood and potential suggestions are being developed.

Previously our lab has shown that carbon-infiltrated carbon nanotube (CI-CNT) surfaces enhance osseointegration and resist biofilm formation, making them attractive possibilities as orthopedic implant materials. For these applications, CI-CNTs and their underlying substrate material must be able to withstand aqueous physiologic conditions. Due to microstructural changes that occur during CI-CNT production, we hypothesized that stainless steel substrate materials experience a loss of their protective, passivating layer, subsequently corroding when immersed in a simulated biological environment. The purpose of the study was to compare corrosion resistance of CI-CNT coated stainless steel substrates to bare stainless steel control samples after two days of incubation in different physiological analog media.

CI-CNTs were grown on 316L stainless steel samples which were sonicated for 20 minutes in isopropyl alcohol and given a 2 minute heat treatment in air at 800°C, followed by a 20 minute growth at the same temperature in ethylene and argon. Carbon infiltration was done for 5 minutes in the same gases at 900°C. The samples were autoclaved and placed into different media including deionized water, phosphor buffered saline solution (PBS), and DMEM culture media. The samples were then incubated for 48 hours at 37°C.

Macroscopic observation showed no obvious signs of corrosion (e.g., discoloration of the liquid media, cloudiness, physical changes in sample appearance) for any of the control samples, or for CI-CNT coated samples in deionized water. In contrast, the CI-CNT coated samples immersed in PBS and culture media exhibited significant discoloration and a cloudy appearance. Subsequent SEM images of the CI-CNT coated samples which had been immersed in culture media and PBS showed foreign residue. Energy dispersive x-ray analysis characterized this residue as having markedly higher levels of sodium and phosphorus than a baseline CI-CNT coated stainless steel sample. SEM images of the bare stainless steel samples and the CI-CNT samples cultured in deionized water showed no signs of corrosion or residue.

Our preliminary results illustrate that media containing salts initiated corrosion of CI-CNT coated stainless steel samples, likely due to disruption of the passivating layer in the substrate. Future work will explore methods for re-establishing the passivating layer in stainless steel materials.

The study examined the integration of science into literacy instruction for the early grades. The study specifically explored how science-infused literacy instruction influenced the quality of compare and contrast science informational text produced by second graders, compared to literacy instruction alone. Additionally, the motivation of the students to read was examined in connection to the quality of the informational text they produced. The participants were second-graders (N = 72) between the ages of 7 – 9 and were enrolled in the first quarter of the school year at a Title 1 school. Seventy-three percent of these students were White, 22% were Hispanic, 2% were Asian, and 1% were Black, with 63% of the students eligible for free or reduced lunch. The treatment group (N = 35) received science-infused literacy instruction and the control group (N = 37) received their regular literacy instruction. Two instruments for measurement were used: a motivation survey which measured the students’ motivation to read, and a weighted writing rubric with an emphasis on signal words, content-specific vocabulary words, and word count, which was used to score the informational text writing samples produced by the students. The students took the reading motivation survey and answered the same informational text writing prompt before and after the instruction. The instruction for compare and contrast writing took place over the course of a four-week unit, and consisted of three 30-minute lessons weekly. The research was designed as quasi-experimental using a paired samples t-test with follow-up effect size measures. The results demonstrate that students in the treatment group produced significantly higher reading motivation scores but wrote lower-quality text, while students in the control group produced lower motivation scores but wrote higher-quality informational text. Implications from this study will be provided for educators and literacy instructional practices, and for researchers and future studies.

Here at Utah State, there are many resources available for students, staff, faculty, and administration to travel to and from campus in eco-friendly ways. While there are many resources readily available, they are not well known across campus. Our initiative is to bring awareness to these hard-working groups and generous programs while incentivizing those who participate in our social media campaign where they will submit creative photos of their sustainable transportation to and from campus. Not only will it be extremely beneficial for these groups and programs across campus to get well-deserved recognition through this initiative, but it will give Aggies the greater opportunity to Go Green and travel to and from campus in an eco-friendly way!

The push for computer science integration in kindergarten classrooms is a surfacing topic in public education in the United States. One approach to this is to integrate computer science with mathematics. However, there is minimal research on computer science and computational thinking as it relates to mathematics in early childhood education. In order to address this need, we are part of a larger research project that is studying the integration of computer science and mathematics in kindergarten classrooms. Specifically, we are exploring computational thinking (CT) elements that we see students engaging in (e.g., algorithmic thinking, debugging, and decomposition) while at the same time exploring mathematics skills that emerge (e.g., measurement, spatial reasoning, and pattern recognition). We study these skills and elements as we teach formal coding instruction using play-based, screen free coding robots. In this presentation, we will present early results of this integration in local kindergarten classrooms. Our main research question is: What CT and mathematics skills and strategies emerge as a result of this formal coding instruction?

Our sample consists of 16 kindergarten students. Groups of 3-4 students participated in six 30-minute coding lessons, followed by an assessment interview. Our data set is made up of video data from both the coding instruction and the assessment interviews, as well as field notes and assessment score sheets. We will present descriptive statistics regarding these assessments, as well as in-depth case studies of 2 students (one student who scored high on their post-test, and one who scored low). We will present data from the videos of their individual experiences as they engaged in formal instruction, as well as data regarding their assessments, in order to answer our research question and analyze what CT and mathematics skills and strategies emerged as a result of their formal coding instruction.

Heart disease is the leading cause of death in the United States. During myocardial infarction cardiac tissue suffers a lack of nutrients and oxygen that leads to the formation of unregenerable scar tissue which causes a loss of myocardial functionality. With the advent of human induced pluripotent stem cells (hiPSC), the promise of engineering autologous cardiac tissues (ECTs) as a translatable treatment to cardiac disease and as a model for pharmaceutical research is ever closer. We create ECTs using iPS-human induced cardiomyocytes (hiCMs) and extra cellular matrix (ECM) derived from a decellularized left ventricle of a porcine heart. Decellularized matrices allow the preservation of important architectural cues found in the native heart for hiCMs development (Momtahan, 2015). Nevertheless, ECTs still face some challenges before they can be useful in a clinical or pharmaceutical research setting i.e. poor ECT contractile force, hiCM maturity, proper cell morphology and architecture, etc. (Dwenger, 2018). In this study, we seek to combine the mechanical cues of the preserved architecture of a decellularized matrix with the spatiotemporal accuracy of optogenetics as a novel technique to stimulate ECT functionality assessed through contractile force, proper hiCM elongation, and alignment.
