New Clues To A Mass Extinction: Colby Geologist Robert Gastaldo And Student Researchers Unearth Evidence That Contradicts Prevailing Models About Ancient Die-Offs, Stephen Collins Mar 2016

New Clues To A Mass Extinction: Colby Geologist Robert Gastaldo And Student Researchers Unearth Evidence That Contradicts Prevailing Models About Ancient Die-Offs, Stephen Collins

Colby Magazine

Colby geologists are rewriting deep time history, altering the script of how scientists understand the mother of all mass extinctions—the End-Permian event that occurred approximately 252 million years ago. Or to suggest that they don’t, in fact, understand it.


The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown Jan 2016

The Real Footprint Of Electric Vehicles, And What That Could Mean For Our Future, Krista Brown

Journal of Environmental and Resource Economics at Colby

This paper looks at the impact of electric vehicles on CO2 emissions specifically based on the type of electricity used in each New England state analyzed. The research looks at the question of whether or not emissions will in fact be lowered as electric cars start to take the majority of vehicles used instead of the conventional cars that take up a much larger percent of the motor vehicles used today. Taking into account the use of electricity and how many sources of electricity also release a substantial amount of emissions, we see how valid the public opinion of electric …


The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler Jan 2016

The Effect Of Information On Avoidance Behavior And Bicycle Transportation: A Study Of “Spare The Air” And Bay Area Bikeshare, Paige W. Whistler

Journal of Environmental and Resource Economics at Colby

This paper seeks to address the effect of “Spare the Air” pollution control alerts in the San Francisco Bay Area in California on the use of Bay Area BikeShare as a form of transportation. By observing the daily alerts on the duration of rides using BikeShare, this paper observes if STA ozone alerts are effective in changing human behavior. The results show that only as a subscriber to the BikeShare program and on an alert day does duration decrease whereas customers regardless of if it is an alert day will ride more often and at longer distances. The results contradict …


Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou Jan 2016

Socioeconomic Attributes’ Relationship To Green Commercial Office Buildings, Tianyang Zhou

Journal of Environmental and Resource Economics at Colby

This paper examines the relationship between the socioeconomic attributes of a state and its green commercial office space adaptation. I hypothesize that a state with high socioeconomic status will have a high green building adoption. Additionally, the high socioeconomic status states may be more likely to invest in green commercial buildings with higher LEED certification levels, and various types of LEED commericial office projects are affected by the socoeconomic attributes differently.


Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda Jan 2016

Do Peers Get Punished: Stock Market Effect Of Bp Oil Spill On Peers, Yuga Koda

Journal of Environmental and Resource Economics at Colby

This paper examines the stock market reaction to the British Petroleum oil spill on April 20, 2010. This event study looks at different sectors that may be affected by the oil spill. It finds that different industries do not have significant abnormal returns, with two exceptions. First, utilities companies have a very small positive abnormal return for a short period of time after the incident. Second, when only looking at BP's direct competitors, there is a statistically significant negative abnormal return, implying that BP's competitors are punished for BP's mishap.


Media Effects On Solar Panel Installations Across 20 States, Casey Romeo Jan 2016

Media Effects On Solar Panel Installations Across 20 States, Casey Romeo

Journal of Environmental and Resource Economics at Colby

This paper looks at the relationship between media coverage of solar power and the solar panel installation at a state level. Specifically, it aims to find if more newspaper articles cause more households to adopt solar energy. Use data from 20 states from 2009 to 2014. I find that there is a modest, yet positive and statistically significant relationship between newspaper articles and installations, which suggests that the media does influence the decision to install solar panels. There is possible endogeneity between these two variables. Disentangling this endogeneity is beyond the scope of this research and would be a topic …


Who Wants The Right To Know? An Analysis Of Gmo-Labeling In California, Sylvia M. Xu Jan 2016

Who Wants The Right To Know? An Analysis Of Gmo-Labeling In California, Sylvia M. Xu

Journal of Environmental and Resource Economics at Colby

There are many studies that have been done to examine what types of voting behavior or patterns are present when voting for environmental ballot measures. This paper examines what characteristics of people are likely to cause them to support Proposition 37 in California, an initiative that, if passed, would require GMO-labeling on all genetically modified foods. Using voting data at a zip code level, I use OLS regression to identify specifically what type of political party, education, occupation, household status, and income levels are more likely to support the bill. I also run weighted regressions by population and number of …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed Jan 2016

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …
