Globally, the incidental capture of non-target species in fisheries (bycatch) has been linked to declines of ecologically, economically, and culturally important marine species. Gillnet fisheries have especially high bycatch due to their non-selective nature, necessitating the development of new bycatch reduction technologies (BRTs). Net illumination is an emerging BRT that has shown promise in reducing bycatch of marine megafauna, including sea turtles, cetaceans, and seabirds. However, little research has been conducted to understand the effects of net illumination on fish assemblages, including bony fish and elasmobranchs (i.e. sharks, rays, and skates). Here, I assessed a 7-year dataset of paired net illumination trials using four different types of light (green LEDs, green chemical glowsticks, ultraviolet (UV) lights, and orange lights) to examine the effects of net illumination on fish catch and bycatch in a gillnet fishery at Baja California Sur, Mexico. Analysis revealed no significant effect on bony fish target catch or bycatch for any light type. There was a significant decrease in elasmobranch bycatch using UV and orange lights, with orange lights showing the most promise for decreasing elasmobranch bycatch, resulting in a 50% reduction in bycatch rates. Analysis of the effects of net illumination on elasmobranch target catch was limited due to insufficient data. These results indicate that the illumination of gillnets may offer a practical solution for reducing fish bycatch while maintaining target catch. More research should be conducted to understand the effects of net illumination in different fisheries, how net illumination affects fisher profit and efficiency, and how net illumination affects fish behavior. Further optimization of net illumination is also necessary before the technology can be recommended on a broader scale.

People have known about mass biodiversity loss and the human actions that drive it for decades now, and yet we have largely failed levels to change our behavior to protect the environment. What’s failing to motivate people to change? Some conservation psychologists have partially blamed the negative way we communicate about environmental issues for paralyzing audiences into doing nothing because they feel helpless to change such a big problem. Instead, many psychologists have called for using positive emotions in communication to motivate an audience, but there’s still little research showing whether that’s a more effective approach or not. To study whether positive or negative emotions are really more motivational for inspiring change, I looked at how different emotions were used in the discourse about an emerging conservation technology called de-extinction as a case study. De-extinction claims to be both a tool for fighting biodiversity loss and for inspiring more positive and inspiring narratives in conservation. In this thesis, I examine those claims by exploring five emotions that the discourse around de-extinction elicits: fear, guilt, grief, awe and hope. I examined the motivating power of those emotions and what kind of actions de-extinction discourse motivates or fails to motivate through the way it uses those emotions. I found that de-extinction discourse erases negative emotions and boosts positive ones as many conservation psychologists recommend. However, de-extinction discourse accomplishes this in misleading ways: it minimizes the sense of importance of ongoing extinctions by framing extinction as a reversible phenomenon, and it overstates the ability of technology alone to combat the extinction crisis without requiring societal change. As a result, de-extinction discourse could risk making the public less motivated to take personal action to forward conservation goals. I conclude that positivity or negativity should not be the central concerns for motivating action, but rather efficacy and honesty.

When earning a teaching certification, there is no curriculum when it comes to the treatment of students with a diagnosis as well as how to educate their fellow classmates. Diagnoses affect the process of child development of the diagnosed as well as the friends and family. Children of all different ages have different responses and reactions to the world of health. Looking at a developmental perspective, teachers can properly educate themselves and their students about these diagnoses. To be able to successfully inform students of diagnoses, there must be an overall understanding of how well they are able to acquire the knowledge. According to Jean Piaget, a key researcher in cognitive development, the age of the child correlates with their overall understanding and comprehension. In his theory, he explained how he believed that the environment of an organism affects how it will respond and adapt to the situations at hand. There are four stages that are connected to age, from infancy to adolescence and adulthood. Therefore, this project will focus on school-age children who are in the concrete operational stage. The concrete operational stage is made up of elementary and early adolescents and focuses on intelligence that is demonstrated through logical and precise thinking of concrete ideas (Huitt, W., & Hummel, J, 2003). This type of thinking applies to all parts of the child’s life and informs their behaviors on how to “adapt” to new information. Knowing this information, we will be able to create a curriculum of lectures, informational videos, worksheets and quizzes that can properly assess the student’s and their knowledge of the diagnoses.

Through this creative project, I analyzed how COVID-19 has affected the theatre industry. I created a mini-documentary following ASU’s production of Runaways, which was performed without an audience. The final product was a combination of pre-filmed and self-taped scenes. I documented how students were still able to learn and cultivate their skills during a time where most things are virtual. In addition, I analyzed how the shift to filmed theatre has changed the definition of live theatre, including increased accessibility. I also explored the importance of theatre through analyzing the themes of musical theatre performances such as Rent and Runaways. During a time where people cannot gather, artists are still finding a way to create and tell stories.

When you are sitting at the terminal waiting for your flight or taking the bus to get to work, have you ever thought about who used your seat last? More importantly, have you ever thought about the last time that seat was cleaned? Sadly, it is uncertain to see if it was properly sanitized in the last hour, yesterday, in the last week, or even last month. Especially during these tough times, everyone wants to be assured that they are always in a safe and healthy environment. Through the Founders Lab, our team is collaborating with an engineering capstone team to bring automated seat cleaning technology into the market. This product is a custom-designed seat cover that is tear-resistant and provides a sanitary surface for anyone to sit on. When someone leaves the seat, a pressure sensor is triggered, and the cover is replaced with a secondary cover that was stored in a UV radiated container. The waterproof fabric and internal filters prevent spills and food crumbs from remaining when the user changes. The reason for bringing this product into the market is due to the unsanitary conditions in many high traffic areas. This technology can be implemented in public transportation, restaurants, sports stadiums, and much more. It will instantly improve the efficiency of sanitation for many businesses and keep a promise to its users that they will never bring something they sat on back home. #Safeseating

In complex consumer-resource type systems, where diverse individuals are interconnected and interdependent, one can often anticipate what has become known as the tragedy of the commons, i.e., a situation, when overly efficient consumers exhaust the common resource, causing collapse of the entire population. In this dissertation I use mathematical modeling to explore different variations on the consumer-resource type systems, identifying some possible transitional regimes that can precede the tragedy of the commons. I then reformulate it as a game of a multi-player prisoner's dilemma and study two possible approaches for preventing it, namely direct modification of players' payoffs through punishment/reward and modification of the environment in which the interactions occur. I also investigate the questions of whether the strategy of resource allocation for reproduction or competition would yield higher fitness in an evolving consumer-resource type system and demonstrate that the direction in which the system will evolve will depend not only on the state of the environment but largely on the initial composition of the population. I then apply the developed framework to modeling cancer as an evolving ecological system and draw conclusions about some alternative approaches to cancer treatment.

This dissertation analyzes the way in which leaders of certain Taiwanese Buddhist organizations associated with a strand of Buddhist modernism called "humanistic Buddhism" use discourse and rhetoric to make environmentalism meaningful to their members. It begins with an assessment of the field of religion and ecology, situating it in the context of secular environmental ethics. It identifies rhetoric and discourse as important but under acknowledged elements in literature on environmental ethics, both religious and secular, and relates this lack of attention to rhetoric to the presence of a problematic gap between environmental ethics theory and environmentalist practice. This dissertation develops a methodology of rhetorical analysis that seeks to assess how rhetoric contributes to alleviating this gap in religious environmentalism. In particular, this dissertation analyzes the development of environmentalism as a major element of humanistic Buddhist groups in Taiwan and seeks to show that a rhetorical analysis helps demonstrate how these organizations have sought to make environmentalism a meaningful subject of contemporary Buddhist religiosity. This dissertation will present an extended analysis of the concept of "spiritual environmentalism," a term developed and promoted by the late Ven. Shengyan (1930-2009), founder of the Taiwanese Buddhist organization Dharma Drum Mountain. Furthermore, this dissertation suggests that the rhetorical methodology proposed herein offers offers a direction for scholars to more effectively engage with religion and ecology in ways that address both descriptive/analytic approaches and constructive engagements with various forms of religious environmentalism.

Despite years of effort, the field of conservation biology still struggles to incorporate theories of animal behavior. I introduce in Chapter I the issues surrounding the disconnect between behavioral ecology and conservation biology, and propose the use of behavioral knowledge in population viability analysis. In Chapter II, I develop a framework that uses three strategies for incorporating behavior into demographic models, outline the costs of each strategy through decision analysis, and build on previous work in behavioral ecology and demography. First, relevant behavioral mechanisms should be included in demographic models used for conservation decision-making. Second, I propose rapid behavioral assessment as a useful tool to approximate demographic rates through regression of demographic phenomena on observations of related behaviors. This technique provides behaviorally estimated parameters that may be applied to population viability analysis for use in management. Finally, behavioral indices can be used as warning signs of population decline. The proposed framework combines each strategy through decision analysis to provide quantitative rules that determine when incorporating aspects of conservation behavior may be beneficial to management. Chapter III applies this technique to estimate birthrate in a colony of California sea lions in the Gulf of California, Mexico. This study includes a cost analysis of the behavioral and traditional parameter estimation techniques. I then provide in Chapter IV practical recommendations for applying this framework to management programs along with general guidelines for the development of rapid behavioral assessment.

Professional environmental scientists are increasingly under pressure to inform and even shape policy. Scientists engage policy effectively when they act within the bounds of objectivity, credibility, and authority, yet significant portions of the scientific community condemn such acts as advocacy. They argue that it is nonobjective, that it risks damaging the credibility of science, and that it is an abuse of authority. This means objectivity, credibility, and authority deserve direct attention before the policy advocacy quagmire can be reasonably understood. I investigate the meaning of objectivity in science and that necessarily brings the roles of values in science into question. This thesis is a sociological study of the roles environmental values play in the decisions of environmental scientists working in the institution of academia. I argue that the gridlocked nature of the environmental policy advocacy debates can be traced to what seems to be a deep tension and perhaps confusion among these scientists. I provide empirical evidence of this tension and confusion through the use of in depth semi-structured interviews among a sampling of academic environmental scientists (AES). I show that there is a struggle for these AES to reconcile their support for environmentalist values and goals with their commitment to scientific objectivity and their concerns about being credible scientists in the academy. Additionally, I supplemented my data collection with environmental sociology and history, plus philosophy and sociology of science literatures. With this, I developed a system for understanding values in science (of which environmental values are a subset) with respect to the limits of my sample and study. This examination of respondent behavior provides support that it is possible for AES to act on their environmental values without compromising their objectivity, credibility, and authority. These scientists were not likely to practice this in conversations with colleagues and policy-makers, but were likely to behave this way with students. The legitimate extension of this behavior is a viable route for continuing to integrate the human and social dimensions of environmental science into its practice, its training, and its relationship with policy.
