Grain-Washing: The Issue With Corn Ethanol As A Sustainable Aviation Fuel, Emily J. Rinn

Scripps Senior Theses

Decarbonizing the aviation sector remains one of the most prevalent obstacles in reducing the United States’ significant contribution to global greenhouse gas emissions. Launched in 2021, the Sustainable Aviation Fuel (SAF) Grand Challenge aims to supply enough fuel to meet 100% of demand by 2050 through reducing its production costs and enhancing its sustainable practices. Corn ethanol feedstock has been proposed to make up as much as half of all SAF production in the 2030 benchmark. This thesis explores the assemblage of corn ethanol – from its true environmental impacts, role in the future SAF market, to research claiming corn …

Desalination And Development: Locating The Missing Masses In Dakar’S Water Network, Marina Riad

Scripps Senior Theses

The introduction of desalination technology to the water network in Dakar, Senegal marks a monumental change in how state and commercial interests aim to solve systemic problems using novel technologies. Desalination aims to transform the ocean surrounding Dakar into potable water, a vital resource in the growing metropolis. However, this desalination project must integrate itself within a network of social, historical, political, commercial, and ecological influences shaping the role of desalination in urban Dakar. With millions of dollars and an entire ocean mobilized towards solving Dakar’s water problems, it may come as a surprise that this project will only provide …

Can Uber And Lyft Save Public Transit?, Emily Zheng

Pomona Senior Theses

I examine whether Uber and Lyft are currently complements or substitutes of public transit, and how partnerships between cities and ride sharing companies can increase their complementary relationship and solve parking and mobility issues. The results suggest that transportation network companies (TNCs) like Uber and Lyft do not have a statistically significant effect on public transit ridership overall, but are complements of public transit for certain populations. Policies that give discounts for TNC rides taken to and from transit stops help solve the first mile / last mile problem, which consequently help increase transit ridership.

The Pursuit Of Innovation: An Analysis Of International Competitive Advantage In A Globalized Knowledge Economy, Tanay Gupte

CMC Senior Theses

With the advent of the internet age, the way in which global society interacts with technology has changed dramatically. The instantaneous availability of information and connectivity, signal the rise of a knowledge economy. This is a system in which the most valuable resource, to nations and private enterprise, is knowledge. This thesis argues that value is created through knowledge flows, which result in innovation and technological advancement. This technological advancement is the primary determinant of a nation’s global competitive advantage in a globalized knowledge economy. This thesis then posits that these innovations are fostered by institutional, social, cultural, economic, and …

Who Will Be The First To Buy Autonomous Vehicles? An Application Of Everett Rogers’ Diffusion Of Innovations Theory, Reilly Jackson Umberger

CMC Senior Theses

Autonomous, otherwise known as self-driving, vehicles represent the future of transportation. Vehicles that drive themselves offer far reaching benefits from increased leisure and productivity for individuals to significant improvements in congestion and infrastructure for governments. The autonomous car will radically change the way we look at transportation, and they are right around the corner. However, the question remains: are we ready? Are we, as a society, ready to hand over the steering the wheel and trust autonomous vehicles with our safety? This paper predicts how the autonomous car will spread through society by analyzing and applying the product qualities and …

Public Land And Its Management: Why The Research Is Not Enough, Corinne Calhoun

Pomona Senior Theses

Ecological research, both basic and applied, can inform management decisions on public land in a number of ways. Most importantly, it can illuminate any negative effects of a given land use practice as well as the causes behind that effect. This type of information can be important to a management agency, such as the BLM, with a multi-use mission as these studies indicate under what management regimes a land use is in contradiction with other goals, such as conservation or restoration.

The current body of research, however, is flawed. In order to make fully informed decisions, land managers are in …

Reducing Automobile Emissions In Southern California: The Dance Of Public Policies And Technological Fixes, Rudi Volti

Pitzer Faculty Publications and Research

For many years I have taught at a small liberal arts college in Southern California. When first-year students arrived at the college in the early 1970s, they settled into the usual things that occupy freshmen. A few weeks would go by, and then they would make a remarkable discovery: tall mountains would appear to the north as autumn weather dissipated the heavy blanket of smog that had obscured them. Today, the air is not perfectly clear in September, but students are aware of the mountains from the day they move into the dormitories. The region's partial victory over smog illustrates …
