Global Warming: Why Is There Debate?, Mackenzie E. Smith Oct 2017

Global Warming: Why Is There Debate?, Mackenzie E. Smith

Student Publications

Previous studies have produced conflicting results for the determining factors of acceptance or rejection of the science behind the global warming phenomenon; some cite religion as a hindrance to the acceptance of this scientific theory [Kilburn 2008], some conclude lack of education is the driving force [Brechin 2003], and some deduce that party affiliation plays the most significant role in determining belief in global warming. In this study, the National Election Survey of 2012 dataset, consisting of 5,916 individual data points from the United States of America, is analyzed to determine the effects of party affiliation on one’s belief in …

Climate Change And Migration: The Intersection Of Climate Change, Migration, And Gender Through Policy, Bridget E. Mccallum Oct 2017

Climate Change And Migration: The Intersection Of Climate Change, Migration, And Gender Through Policy, Bridget E. Mccallum

Student Publications

This article explores the intersectional nature of the issue of climate change, especially as it relates to migration. Both migration and climate change are issues of global significance, with benefits and burdens distributed unevenly across gender, racial, and class lines. This intersectional approach takes note of the unequal power structures at play when attempting to combat these issues with policy.

Spatial Models To Account For Variation In Observer Effort In Bird Atlases, Andrew M. Wilson, Daniel W. Brauning, Caitlin Carey, Robert S. Mulvihill Aug 2017

Spatial Models To Account For Variation In Observer Effort In Bird Atlases, Andrew M. Wilson, Daniel W. Brauning, Caitlin Carey, Robert S. Mulvihill

Environmental Studies Faculty Publications

To assess the importance of variation in observer effort between and within bird atlas projects and demonstrate the use of relatively simple conditional autoregressive (CAR) models for analyzing grid-based atlas data with varying effort. Pennsylvania and West Virginia, United States of America. We used varying proportions of randomly selected training data to assess whether variations in observer effort can be accounted for using CAR models and whether such models would still be useful for atlases with incomplete data. We then evaluated whether the application of these models influenced our assessment of distribution change between two atlas projects separated by twenty …

Next Page

This edition of Next Page is a departure from our usual question and answer format with a featured campus reader. Instead, we asked speakers who participated in the College’s recent Student Solidarity Rally (March 1, 2017) to recommend readings that might further our understanding of the topics on which they spoke.

Investigating The Magnitude And Range Of The Urban Heat Island Within Gettysburg, Pennsylvania, Samuel S. Thompson, Rachel A. Wilkins Apr 2017

Investigating The Magnitude And Range Of The Urban Heat Island Within Gettysburg, Pennsylvania, Samuel S. Thompson, Rachel A. Wilkins

Student Publications

Cities experience UHIs due to the thermal properties (albedo, thermal emittance, radiative flux, and heat capacity) of human-made substances and urban geometry. This study investigated the existence of an urban heat island (UHI) in Gettysburg, Pennsylvania. The goal of this project was to assess whether a small-scale city like Gettysburg demonstrates an UHI effect and, if present, the extent and magnitude of the UHI. We hypothesized that (1) temperatures within the city are significantly higher than the surrounding area, (2) the magnitude of the UHI will diminish as distance from the city center increases, and (3) the UHI will not …

Getting That Sinking Feeling: Analysis And Impacts Of Sea Level Rise On Three National Parks Along The East Coast, Usa, Julia K. Deros, Amanda L. Thibault, Amy B. True Apr 2017

Getting That Sinking Feeling: Analysis And Impacts Of Sea Level Rise On Three National Parks Along The East Coast, Usa, Julia K. Deros, Amanda L. Thibault, Amy B. True

Student Publications

Due to global climate change, sea level rise (SLR) has become a threat for future generations, but the extent of this danger is unknown. To help understand the possible effects of SLR on the east coast of the United States, we studied three national parks: Acadia National Park (ACAD), Assateague Island National Seashore (ASIS) and Everglades National Park (EVER). We predicted that ACAD would be less affected by SLR than ASIS and EVER due to the construction of its beach profile. By measuring the beach profile, we found that Sand Beach in ACAD was reflective with an average slope of …

Geographic Variation Of Cirques On Iceland: Factors Influencing Cirque Morphology, Heather A. Ipsen, Rachael E. Grube, Jessica F. Lee, Sarah M. Principato Mar 2017

Geographic Variation Of Cirques On Iceland: Factors Influencing Cirque Morphology, Heather A. Ipsen, Rachael E. Grube, Jessica F. Lee, Sarah M. Principato

Environmental Studies Faculty Publications

Cirques are one of the most common glacial landforms in alpine settings. They also provide important paleoclimate information (e.g. Meierding 1984; Evans 2006). The purpose of this study is to fill in gaps in the climate record of Iceland by conducting a quantitative analysis of cirques in three regions in Iceland: Tröllaskagi, the East Fjords, and Vestfirðir. Iceland, located in the center of the North Atlantic Ocean, contains many small glaciers, in addition to large ice caps. The glaciers on Iceland are particularly sensitive to variations in oceanic and atmospheric circulation (Andresen et al. 2005; Geirsdóttir et al., 2009; Ólafsdóttir …

New Constraints On The Timing And Pattern Of Deglaciation In The Húnaflói Bay Region Of Northwest Iceland Using Cosmogenic 36ca Dating And Geomorphic Mapping, Amanda N. Houts, Joseph M. Licciardi, Sarah M. Principato, Susan H. Zimmerman, Robert C. Finkel Mar 2017

New Constraints On The Timing And Pattern Of Deglaciation In The Húnaflói Bay Region Of Northwest Iceland Using Cosmogenic 36ca Dating And Geomorphic Mapping, Amanda N. Houts, Joseph M. Licciardi, Sarah M. Principato, Susan H. Zimmerman, Robert C. Finkel

Environmental Studies Faculty Publications

Understanding the evolution and timing of changes in ice sheet geometry and extent in Iceland during the Last Glacial Maximum (LGM) and subsequent deglaciation continues to stimulate much active research. Though many previous studies have advanced our knowledge of Icelandic ice sheet history preserved in marine and terrestrial settings (e.g., Andrews et al., 2000; Norðdahl et al., 2008), the timing of ice margin retreat remains largely unknown in several key regions. Recently published 36Cl surface exposure ages of bedrock surfaces and moraines in the West Fjords (Brynjólfsson et al., 2015) contribute important progress in establishing more precise age control of …

Ai Education: Open-Access Educational Resources On Ai, Todd W. Neller Jan 2017

Ai Education: Open-Access Educational Resources On Ai, Todd W. Neller

Computer Science Faculty Publications

Open-access AI educational resources are vital to the quality of the AI education we offer. Avoiding the reinvention of wheels is especially important to us because of the special challenges of AI Education. AI could be said to be “the really interesting miscellaneous pile of Computer Science”. While “artificial” is well-understood to encompass engineered artifacts, “intelligence” could be said to encompass any sufficiently difficult problem as would require an intelligent approach and yet does not fall neatly into established Computer Science subdisciplines. Thus AI consists of so many diverse topics that we would be hard-pressed to individually create quality learning …

Is There A Path For Green Growth? Evidence From India, Thuc Anh Thi Trinh Jan 2017

Is There A Path For Green Growth? Evidence From India, Thuc Anh Thi Trinh

Gettysburg Economic Review

This paper uses historical temperature fluctuations in India to identify its effects on economic growth rates. Using a climate-adjusted form of the Solow growth model, I find that one degree Celsius increase in temperature decreases GDP per capita growth by 0.71%. This finding informs debates over the role of climate on economic development and suggests the possibility of a green path for economic growth, a policy agenda that is both sustainable and pro-growth.
