Review: Robert H. Nelson, The New Holy Wars: Economic Religion Vs. Environmental Religion In Contemporary America, Andre Wakefield Jul 2011

Review: Robert H. Nelson, The New Holy Wars: Economic Religion Vs. Environmental Religion In Contemporary America, Andre Wakefield

Pitzer Faculty Publications and Research

This is a book review of Robert H. Nelson's The New Holy Wars: Economic Religion vs. Environmental Religion in Contemporary America. Nelson argues that environmentalism and economics represent competing religious worldviews. Within this framework, debates over issues like global warming and acid rain become veiled theological disputes between these two “secular religions.” Nelson paints with a broad, aggressive brush. This is both the strength and weakness of his book, as he conjures a world of epic battles between the economic faithful, who worship material progress, and the environmentally pious, who bemoan the corruption visited by humans upon the natural world. …

Subaerial Freshwater Stromatolites In Deer Cave, Sarawak – A Unique Geobiological Cave Formation, Joyce Lundberg, Donald A. Mcfarlane Jan 2011

Subaerial Freshwater Stromatolites In Deer Cave, Sarawak – A Unique Geobiological Cave Formation, Joyce Lundberg, Donald A. Mcfarlane

WM Keck Science Faculty Papers

A suite of distinctive freshwater subaerial phosphatic stromatolites is developed close to the northeastern entrance of Deer Cave, Gunung Mulu National Park, Sarawak, Borneo, in conditions of very low light but ample supply of nutrients from guano. These stromatolites are not particulate; they are composed of alternating layers of more porous and more dense amorphous hydroxylapatite. This biomineralization occurs as moulds of coccoid (the majority) and filamentous (less abundant) cyanobacteria. Mineralization occurs at a pH of ~ 7.0 in the extracellular sheaths and in micro-domains of varying carbonate content in the surrounding mucus of the biofilm. The most recent surfaces …


Energy Storage: Technology For A More Efficient Grid, Noah Proser Jan 2011

Energy Storage: Technology For A More Efficient Grid, Noah Proser

CMC Senior Theses

Energy storage technologies have the potential to revolutionize the electric grid by allowing for the integration of renewable generation while increasing the utilization and efficiency of current grid assets. These technologies include pumped hydroelectric storage, compressed air energy storage (CAES), flywheels, batteries, thermal energy storage (TES), super capacitors, and superconducting magnetic energy storage (SMES). While energy storage has been implemented in some areas, its benefits are greatly undervalued by current regulatory frameworks leading to suboptimal outcomes for grid operators, utilities, and ratepayers. Large-scale adoption of storage technologies will require regulatory frameworks that recognize the benefits of grid-scale storage across generation, …


Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott Jan 2011

Overcoming The Obstacles To Sustainability In Ghana, Ashley M. Scott

CMC Senior Theses

For several decades following its independence from Great Britain, Ghana’s policies continued to promote over-extraction of natural resources to the detriment of its economy and rural communities. Agricultural and forestry policy has gradually evolved to foster more sustainable and equitable practices, as in building partnerships with the private sector to fund infrastructure improvements. Policy has recently recognized the dire need to adopt agricultural practices and means of forest resource extraction that are compatible with ecological stewardship. However, many shortcomings are still apparent. Large logging operations completely disregard forestry regulations with impunity, whereas rural sustenance extractors are severely punished in the …


A Secure Behavior Modification Sensor System For Physical Activity Improvement, Alan Price Jan 2011

A Secure Behavior Modification Sensor System For Physical Activity Improvement, Alan Price

CGU Theses & Dissertations

Today, advances in wireless sensor networks are making it possible to capture large amounts of information about a person and their interaction within their home environment. However, what is missing is how to ensure the security of the collected data and its use to alter human behavior for positive benefit.

In this research, exploration was conducted involving the "infrastructure" and "intelligence" aspects of a wireless sensor network through a Behavior Modification Sensor System. First was to understand how a secure wireless sensor network could be established through the symmetric distribution of keys (the securing of the infrastructure), and it involves …


Coalitions And Cliques In The School Choice Problem, Sinan Aksoy, Alexander Adam Azzam, Chaya Coppersmith, Julie Glass, Gizem Karaali, Xueying Zhao, Xinjing Zhu Jan 2011

Coalitions And Cliques In The School Choice Problem, Sinan Aksoy, Alexander Adam Azzam, Chaya Coppersmith, Julie Glass, Gizem Karaali, Xueying Zhao, Xinjing Zhu

Pomona Faculty Publications and Research

The school choice mechanism design problem focuses on assignment mechanisms matching students to public schools in a given school district. The well-known Gale Shapley Student Optimal Stable Matching Mechanism (SOSM) is the most efficient stable mechanism proposed so far as a solution to this problem. However its inefficiency is well-documented, and recently the Efficiency Adjusted Deferred Acceptance Mechanism (EADAM) was proposed as a remedy for this weakness. In this note we describe two related adjustments to SOSM with the intention to address the same inefficiency issue. In one we create possibly artificial coalitions among students where some students modify their …


Cultivating Youth Earth Connections Summer Internship Program (Yec): A Hands-On Environmental Justice Focused Farming Program At The High School Level, Samuel Lewis Jan 2011

Cultivating Youth Earth Connections Summer Internship Program (Yec): A Hands-On Environmental Justice Focused Farming Program At The High School Level, Samuel Lewis

Pomona Senior Theses

YEC’s main goal was to open dialogue with high school students from under resourced communities about environmental injustices and to create and explore positive alternatives. The summer program, which was funded by the 2010 Davis Projects for Peace and the Pomona College Summer Undergraduate Research Project Award, included a group of 11 high school students from Pomona, Montclair, La Puente, and Chino Hills, CA. The students were paid to participate in the program for 6 weeks in the summer of 2010, five days a week, for 30 hours each week. The program was designed to consistently connect movements for food …
