The free-base tetra-tolyl-porphyrin and the corresponding cobalt and iron porphyrin complexes were synthesized and characterized to show that this class of compound can be promising, tunable catalysts for carbon dioxide reduction. During cyclic voltammetry experiments, the iron porphyrin showed an on-set of ‘catalytic current’ at an earlier potential than the cobalt porphyrin’s in organic solutions gassed with carbon dioxide. The cobalt porphyrin yielded larger catalytic currents, but at the same potential as the electrode. This difference, along with the significant changes in the porphyrin’s electronic, optical and redox properties, showed that its capabilities for carbon dioxide reduction can be controlled by metal ions, allotting it unique opportunities for applications in solar fuels catalysis and photochemical reactions.

The globalized food system has caused detriments to the environment, to economic justice, and to social and health rights within the food system. Due to an increasing concern over these problems, there has been a popular turn back to a localized food system. Localization's main principle is reconnecting the producer and consumer while advocating for healthy, local, environmentally friendly, and socially just food. I give utilitarian reasons within a Kantian ethical framework to argue that while partaking in a local food system may be morally good, we cannot advocate for localization as a moral obligation. It is true from empirical research that localizing food could solve many of the environmental, economic, social, and health problems that exist today due to the food system. However, many other countries depend upon the import/export system to keep their own poverty rates low and economies thriving. Utilitarian Peter Singer argues that it would be irresponsible to stop our business with those other countries because we would be causing more harm than good. There are reasons to support food localization, and reasons to reject food localization. Food localization is a moral good in respect to the many benefits that it has, yet it is not a moral obligation due to some of the detriments it may itself cause.

The purpose of this thesis is to study the issue of animal agriculture and why people chose to consume sentient beings such as pigs, chickens, and cows yet house equally as sentient and intelligent beings such as dogs and cats. I want to understand people’s reasoning and logic behind discriminating who they love versus who they eat. This thesis intends to help readers become more aware of the cognitive dissonance behind the food choices that most Americans make up to three times a day. Data was collected through Google Form surveys for freshman living in the dorms at Barrett, The Honors College. The results showed that animal intelligence did not factor in people’s decision to consume their parts. Additionally, this study concluded that participants are more likely to feel less guilty when they are under the false belief that the meat they purchased was mislabeled with terms such as ‘humane slaughter.’

Description
Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion.

Social relationships are the single most factor that create joy in human lives. And yet, the ways we are building our cities and structuring our lives reduces our chances of interaction and increases isolation. Creating more public spaces may be a possible solution to this problem of declining social cohesion. Public spaces have been shown to improve rates of social cohesion and social interaction. They have also been show to have positive effects on physical health, local economies, the natural environment, reducing crime rates and psychological health. Creating public spaces in areas that are low-income or have limited amounts of space can be very challenging. This paper profiles options of community created spaces, space public spaces and temporary public spaces. All of which are options for low-income and limited space communities. The paper concludes with the summery of an active project to create a public space in such a community through a joint-use agreement.

As consumers shift their values toward sustainability, environmentalism, and social issues, industries face increased pressure to engage with sustainability and make their sustainable practices transparent to consumers. While luxury fashion has shifted toward sustainable practices, little conclusive research exists to understand how consumers respond to such practices. This research explores whether the use of recycled materials affects a luxury brand more than a mainstream brand. My results indicate that the use of recycled materials is harmful for a luxury brand but has no impact on the mainstream brand.

Current literature on sustainability education and its core competencies (systems thinking, normative, interpersonal, strategic, and future thinking) has yet to acknowledge the K-12 level, concentrating instead on higher-level institutions. To initiate study at the critical K-12 level, a curriculum module composed of four lessons to address the wicked sustainability problem of drought in the Sonoran Desert was developed, piloted, and evaluated. The framework of each lesson combined the core competencies and the 5Es pedagogy (engage, explore, explain, elaborate, and evaluate). Two lessons were successfully piloted in two seventh grade middle-school science classes in Phoenix, Arizona. Topics addressed were the water cycle, types of drought, water systems, and mitigation methods. Evaluation determined a high level of student engagement. Post-pilot teacher questionnaires revealed a high degree of support for inclusion of sustainability education and core competencies addressing drought in future opportunities. It is concluded that lessons in the future can adopt the core competences of sustainability with the support of educators in Arizona.

Brundtland’s definition of sustainability is the ability to “meet the needs of the present without compromising the ability of future generations to meet their needs” (IISD, 2021). But what if there are no future generations? Social sustainability, the sector of sustainability that foregrounds the well-being and livelihoods of people (and thereby continuation of humanity), is included in definitions within the sustainability field, but less developed in sustainability practice. In an effort to bridge this gap of knowledge, 14 U.S. cities and over 100 sustainability policies were analyzed for their social sustainability performance. An eight-item analytical framework that deals with differing areas of social equity guided the analysis. Results found that most cities’ sustainability departments fell short of truly addressing social sustainability concerns. Out of the eight items, the most frequently addressed were housing security and racial and gender equality whereas few, if any, cities addressed the more specific social concerns of immigration, technology and media, or arts/cultural preservation. Future research is recommended to gain a better understanding of the ways existing cities can improve in this area.

Reducing the amount of error and introduced data variability increases the accuracy of Western blot results. In this study, different methods of normalization for loading differences and data alignment were explored with respect to their impact on Western blot results. GAPDH was compared to the LI-COR Revert total protein stain as a loading control. The impact of normalizing data to a control condition, which is commonly done to align Western blot data distributed over several immunoblots, was also investigated. Specifically, this study addressed whether normalization to a small subset of distinct controls on each immunoblot increases pooled data variability compared to a larger set of controls. Protein expression data for NOX-2 and SOD-2 from a study investigating the protective role of the bradykinin type 1 receptor in angiotensin-II induced left ventricle remodeling were used to address these questions but are also discussed in the context of the original study. The comparison of GAPDH and Revert total protein stain as a loading control was done by assessing their correlation and comparing how they affected protein expression results. Additionally, the impact of treatment on GAPDH was investigated. To assess how normalization to different combinations of controls influences data variability, protein data were normalized to the average of 5 controls, the average of 2 controls, or an average vehicle and the results by treatment were compared. The results of this study demonstrated that GAPDH expression is not affected by angiotensin-II or bradykinin type 1 receptor antagonist R-954 and is a less sensitive loading control compared to Revert total protein stain. Normalization to the average of 5 controls tended to reduce pooled data variability compared to 2 controls. Lastly, the results of this study provided preliminary evidence that R-954 does not alter the expression of NOX-2 or SOD-2 to an expression profile that would be expected to explain the protection it confers against Ang-II induced left ventricle remodeling.

As temperatures increase across the United States, some populations are more at risk for heat-related death and illness than others. One of these at-risk demographics is mobile home and trailer park inhabitants, who are disproportionately represented among indoor heat-related deaths (Solís, “Heat, Health”). In this paper, we outline a cost-benefit analysis that was used to calculate the net present economic value of projects related to reducing heat burden on mobile home owners and parks in Maricopa County. We use this model to assess solutions developed by student teams under the Knowledge Exchange for Resilience’s Summer Heat Resilience Challenge. We find that one of the seven solutions has a positive net present value (NPV) even in the lowest effectiveness (10%), while three more solutions have a positive NPV in the mid-level (50%) effectiveness scenario, showcasing their economic viability.

The goal of this research was to analyze the impact of consumer behavior on the sustainability of the fast fashion industry, specifically in regards to the framework of the Triple Bottom Line. First, a review of relevant literature investigating the three aspects of the Triple Bottom Line (environmental, social, and economic) as it pertains to the fast fashion industry was conducted to provide context for this research. Research methods utilized scholarly articles and journals along with companies’ CSR reports to determine the course of development of the fast fashion industry over time. Additionally, the impact of consumer behavior was investigated and linked to trends observed in the production and business practices of the industry over time. Based on the analysis of the influence of past consumer behavior on the industry, it was clear consumers play a major role in the industry and its sustainability in terms of the Triple Bottom Line. This suggests that the unsustainability of the fast fashion industry is due in part to consumer behavior and the retailers themselves, which is important to understand for the industry going forward as it aims to improve overall sustainability.
