The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings Jun 2008

The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings

Honors Theses

The majority of the NYC water supply is provided by a system of dams and reservoirs that have been created in upstate New York. As the owner of this water supply system, NYC is responsible for managing each of the dams and reservoirs within the system. This responsibility includes upholding dam regulations in order to ensure the safety of the citizens of the surrounding area and to lesson any environmental impacts that may occur due to the water supply system. Of the 30 dams owned by NYC, however, 25 of them have been identified at a high-hazard level according the …


Effects Of Context Of Natural And Artifactual Objects On Categorization, Linsey Walker May 2008

Effects Of Context Of Natural And Artifactual Objects On Categorization, Linsey Walker

Honors Theses

Categorization of animals and vehicles in different contexts was investigated in three experiments using event related potentials (ERPs). The presence of a background and congruency of the background in relation to the object were both manipulated in order to determine the effects of context on visual processing. In Experiment 1, adults were presented with images of animals and vehicles in two conditions: situated in a congruent context (e.g. an animal in a field) and in the absence of a context (an animal in a white homogeneous background). In experiment 2, adults were presented with images of animals and vehicles in …


Foundations And Interpretations Of Quantum Mechanics, Cory Johnson May 2008

Foundations And Interpretations Of Quantum Mechanics, Cory Johnson

Honors Theses

The first famous thought experiment of Einstein gives rise to his theories of relativity, the bedrock of modern astrophysics and cosmology. His second famous thought experiment begins the investigation into the foundations of quantum mechanics. It leads to a paradox, inspiring various 'no-go' theorems proven by Bell, Kochen, and Specker. Physicists and philosophers worldwide become increasingly dissatisfied with the probabilistic complementarity interpretation (Born-Bohr) and eventually offer their own accounts of the theory. By the end of the 20th century two alternative approaches stand out as the best candidates: Both the hidden variables interpretation (de Broglie-Bohm) and the many worlds interpretation …

Designing A Green Graduation At Colby College, Alaina J. Clark May 2008

Designing A Green Graduation At Colby College, Alaina J. Clark

Honors Theses

Lately, there has been a growing trend of “green” events. The increase in understanding and discussions about the future climate has caused people throughout the world to become concerned about their contribution to climate change. This is true in the Northeast United States as well. Many New England colleges and universities, including Colby College in Waterville, Maine, are becoming leaders in climate change mitigation. As a teaching institution, Colby has recognized that public education is an important part of the solution to the climate crisis. Colby also understands that commencement weekend is an ideal opportunity for climate change education. As …


Hydrologic And Water Quality Assessment Of Miller Run: A Study Of Bucknell University’S Impact, Alison C. Schaffer May 2008

Hydrologic And Water Quality Assessment Of Miller Run: A Study Of Bucknell University’S Impact, Alison C. Schaffer

Honors Theses

Human development causes degradation of stream ecosystems due to impacts on channel morphology, hydrology, and water quality. Urbanization, the second leading cause of stream impairment, increases the amount of impervious surface cover, thus reducing infiltration and increasing surface runoff of precipitation, which ultimately affects stream hydrologic process and aquatic biodiversity. The main objective of this study was to assess the overall health of Miller Run, a small tributary of the Bull Run and Susquehanna River watersheds, through an integrative hydrologic and water quality approach in order to determine the degree of Bucknell University’s impact on the stream. Hydrologic conditions, including …

Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell Jan 2008

Effect Of Observed Biological And Non-Biological Movement On Human Action And Coordination, Walter L. Campbell

Honors Theses

Recently, it has been demonstrated that an individual’s rhythmic limb movements exhibit greater variability when viewing spatially incongruent biological limb movements, but not when viewing spatially incongruent non-biological movements. Some researchers have concluded that a ‘mirror-neuron system’ might mediate the intrinsic bidirectional link between perception and action underlying interpersonal, but not environmental, coordination (e.g., Kilner et al., 2003; Tognoli et al., 2007). The current study aimed to: 1) contest this recent finding; and 2) demonstrate that the self-organized entrainment processes of coupled oscillators can explain the differing influences of biological and non-biological movements. In the first experiment, participants intentionally coordinated …


Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips Jan 2008

Phosphorus Primer For Maine’S Lakes, Lindsay B. Philips

Honors Theses

Phosphorus plays a major role in aquatic systems and the life that they support. It is a macronutrient that constitutes 0.5lf microorganisms and zooplankton by mass. Phosphorus is of great importance in terrestrial, agricultural, and plant systems as a macronutrient, and when it comes to aquatic systems, we tend to look at phosphorus in terms of its influence on lake primary productivity. Lakes are often phosphorus sinks because they are maintained by hydrological sources that are capable of causing nutrient influx. To understand phosphorus cycling in lake systems, it is important to consider the many sources and forms of phosphorus …


Carbon Neutrality At Colby College, Jamie K. O’Connell Jan 2008

Carbon Neutrality At Colby College, Jamie K. O’Connell

Honors Theses

Carbon neutral is a term used to describe any organization, entity, or process that has a net greenhouse gas (GHG) emissions level of zero (Dautremont-Smith et al. 2007a). Since carbon neutrality only requires a net greenhouse gas emissions level of zero, organizations do not need to eliminate all carbon pollution to become carbon neutral. Net emissions differ from gross emissions in that gross emissions are the sum of all emissions released by the individual or entity, whereas net emissions are equivalent to the gross emissions minus any carbon offsets. A carbon offset is any activity that reduces carbon emissions so …


Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson Jan 2008

Separating People And Wildlife: Zoning As A Conservation Strategy For Large Carnivores, Courtney L. Larson

Honors Theses

Large carnivores are some of the world’s most difficult species to conserve because of their large spatial requirements, low population density, and high potential for conflict with humans. However, large carnivores are valuable for ecological, cultural, and ethical reasons. Carnivore management can take a wide variety of forms, including translocation, sterilization, livestock compensation programs, regulated hunting, improved livestock husbandry practices, and zoning, among others. The objective of this thesis was to conduct a comparative analysis of examples of zoning from around the world to examine whether it is an effective carnivore management strategy.

Analysis of twelve case studies showed that …
