Although social hierarchies are commonly found all throughout nature, the underlying mechanisms of their formation are still ambiguous. Hierarchies form through a wide range of interactions between subordinate and dominant individuals, and the ponerine ant Harpegnathos saltator provides the perfect model to explore such dominance behaviors. When the queen is absent or her fecundity levels drop below a certain threshold, H. saltator workers undergo a dominance tournament, in which several individuals emerge as gamergates, reproductive workers that are not queens. During this tournament, several characterizable dominance behaviors are exhibited (antennal dueling, dominance biting, and policing), which can be used to study the behavioral and social dynamics in the formation of a reproductive hierarchy. Colonies of 15, 30, 60, and 120 workers were created in duplicate, and their dominance tournaments were recorded to study how these interactions impact gamergate establishment. Rather than studying these behaviors as isolated incidents, responses to policing behaviors (timid, neutral, or aggressive) and their duration were recorded along with the frequency of dueling. Three groups were determined: dueling future gamergates (DFG), dueling future non-gamergates (DFNG) and non-dueling individuals (ND). DFNG received many more policing attacks and the duration of these interactions lasted much longer. DFG consistently exhibited the most dueling. Timid and neutral responses were more common than aggressive responses, perhaps due to energy conversation purposes. Peaks in dueling correspond to peaks in policing, highlighting the dynamic behavioral interactions necessary for the formation of a reproductive hierarchy.

Food waste is a crucial issue in stores, restaurants and other institutions. Specifically, there is a high amount of food waste in grocery stores, especially in the produce section. As a result, environmental damage occurs, and many individuals struggle to have food in their homes. This thesis will analyze the cause, quantity, and effect of this waste, and how it can be changed or mitigated. An overarching question was posed to analyze these causes and effects of waste, asking how does the amount of produce waste that occurs in Scottsdale, Arizona contribute to environmental issues and what is being done to remedy this issue? As this is a difficult question to answer on its own, the research was broken down into two more answerable questions, which are Why does produce get wasted in grocery stores? How much of this occurs? and What remedies already exist to limit/reduce this waste? These questions are important because they contribute to knowledge and understanding about food waste, consumer waste, as well as the overall environmental impact of being wasteful. It is also important for both retailers and consumers to understand that waste has an immense and negative impact on the environment and contributes to climate change, and that taking steps to reduce this waste is essential.

In this project, I analyze representative samples from three different fashion brands’ sustainability-related informational materials provided to the public through their websites, annual reports, and clothing tags that promote the company’s environmental initiatives. The three companies were chosen because they each represent global fashion- they are all extremely large, popular, and prevalent brands. These materials are evaluated against three frameworks for identifying deceptive greenwashing claims. I identify instances in which these frameworks are successful in categorizing deceptive claims from these companies as well as instances in which they appear to be vulnerable. To address the vulnerabilities I discover in the three existing frameworks for identifying greenwashing, I propose six new guidelines to be used in conjunction with these frameworks that will help to ensure that consumers can have a more ample toolbox to identify deceptive sustainability claims.

The perception that homosexuality is an immoral affliction and an innovation from Western cultures is prevalent throughout Africa, specifically in six case countries: Togo, Nigeria, Senegal, Uganda, Zimbabwe, and Namibia. This thesis seeks to demonstrate that homophobia, not homosexuality, is the true Western import. Additionally, it will analyze the background and colonial histories of my six dossier countries, their current laws surrounding LGBT+ rights, the social and legal repercussions of being LGBT+, and the consequences of state-sponsored homophobia in terms of justice, international law, and the future of each country. Based on my research, all these case countries use colonial-era provisions, penal codes, and religious norms to discriminate against homosexuals, which operate under legally-mandated “morality,” a notion inherently subjective. Additionally, the most targeted groups are gay men and transgender people, while lesbians and bisexual women are rarely targeted and convicted compared to homosexual men. This is due to various social, legal, and religious factors regarding the high importance of patriarchy and masculinity. Ultimately, this thesis concludes that European colonization in Togo, Nigeria, Senegal, Uganda, Zimbabwe, and Namibia introduced new legal norms that persecuted pre-colonial practices of homosexuality under the guise of morality. Now, the repercussions are rampant and dangerous (especially for homosexual men and transgender people) and cannot be overcome without radical changes to local legal and social systems.

With the dissolution of the old forms of power has come a new heteronomy: that of the screen. The individual is in stasis, caught between the old forms of control and the new, but unable to imagine a better, liberated future. What is responsible for this interregnum? The answer lies in analyzing these new forms of control, their effects on the subject, and the material, historical processes behind them. This paper looks specifically at social media and how it has come to limit autonomy and commodify human experience and personhood. Drawing from Theodor Adorno’s Theory of Pseudo Culture, it seeks to describe the ways in which social media both erodes and administers subjectivity. Culture, now subject to the economic imperatives of capitalism, no longer contributes to the development of individuality. By referencing Karl Marx’s Capital and C. Wright Mill’s “The Competitive Personality”, this paper describes how social media expands commercial imperatives outside of the bounds of the workplace and into everyday life. The paper concludes by drawing on Herbert Marcuse’s One Dimensional Man in order to describe how social media neutralizes oppositional sentiments. Even the seemingly spontaneous expressions of dissent found on social media become a conservative force, stymieing real world organization through the repressive desublimation of revolt. In addition to understanding the dominating effects of the screen, this paper seeks to map the contours of neoliberal subjectivity.

With the rise of global warming and the growing energy crisis, scientists have pivoted from typical resources to look for new materials and technologies that can aid in advancing renewable energy efforts. Perovskite materials hold the potential for making high-efficiency, low-cost solar cells through solution processing of Earth abundant materials; however, scalability and manufacturability remain a challenge. In order to transition from small scale processing in inert environments via spin coating to higher throughput processing in ambient conditions via blade coating, the fundamentals of perovskite crystallization must be understood. Classical nucleation theory, the LaMer relation, and nonclassical crystallization considerations are discussed to provide a mechanism by which gellan gum, a nontoxic biopolymer from the food industry, has enabled quality halide perovskite thin films. Specifically, this research aims to study the effects of gellan gum in improving perovskite manufacturability by controlling crystallization through indirect alteration of evaporation and supersaturation rates by modifying fluid dynamics and the free energy associated with nucleation and growth. Simply, gellan gum controls crystallization to enable the fabrication of promising scalable PVSK devices in open air.
