Effect Of Base-Pairing Partner On The Thermodynamic Stability Of The Diastereomeric Spiroiminodihydantoin Lesion, Brian Gruessner, Megana Dwarakanath, Elizabeth Stewart, Yoon Bae, Elizabeth R. Jamieson

Chemistry: Faculty Publications

Oxidation of guanine by reactive oxygen species and high valent metals produces damaging DNA base lesions like 8-oxo-7,8-dihydroguanine (8-oxoG). 8-oxoG can be further oxidized to form the spiroiminodihydantoin (Sp) lesion, which is even more mutagenic. DNA polymerases preferentially incorporate purines opposite the Sp lesion, and DNA glycosylases excise the Sp lesion from the duplex, although the rate of repair is different for the two Sp diastereomers. To further understand the biological processing of the Sp lesion, differential scanning calorimetry (DSC) studies were performed on a series of 15-mer DNA duplexes. The thermal and thermodynamic stability of each of the Sp …

Experimental Evidence For Drought Induced Alternative Stable States Of Soil Moisture, David A. Robinson, Scott B. Jones, Inma Lebron, Sabine Reinsch, Maria T. Dominguez, Andrew R. Smith, Davey L. Jones, Miles R. Marshall, Bridget A. Emmett

Plants, Soils, and Climate Faculty Publications

Ecosystems may exhibit alternative stable states (ASS) in response to environmental change. Modelling and observational data broadly support the theory of ASS, however evidence from manipulation experiments supporting this theory is limited. Here, we provide long-term manipulation and observation data supporting the existence of drought induced alternative stable soil moisture states (irreversible soil wetting) in upland Atlantic heath, dominated by Calluna vulgaris (L.) Hull. Manipulated repeated moderate summer drought, and intense natural summer drought both lowered resilience resulting in shifts in soil moisture dynamics. The repeated moderate summer drought decreased winter soil moisture retention by ∼10%. However, intense summer drought, …

The Qualitative Report

This study employed ethnographical and phenomenological methods to explore the lived experiences and career of a Hong Kong secondary school physical education (PE) teacher (Wharton) in order to embody his versatile roles through phenomenological description of a lived body itself and the lived world. The central research question is “How does a male secondary school PE teacher manage his work life and the embodiment of his professional roles?” Data collection techniques were in-depth interviewing, participant observation and field notes, participant’s reflection documentation and visual elicitation. Concepts of “play to learn,” “professional development” and “political empowerment” were used to examine Wharton’s …

The Role Of Service-Learning And Mentoring In The Early Career Development Of A Research Methodologist, Cheryl H. Keen, Heather Pease

The Qualitative Report

Anxiety about statistics may impede new scholars from developing quantitative research skills and from sharing those skills in service-learning, internship, and work settings. Using an interpretive case study design with a convenience sample of one emerging student leader in a collaborative university-community service-learning research project, we explored the question “How did the career path of a quantitatively skilled researcher develop?” Data collected over a 3-and-a-half-year period included 7 semi-structured interviews with the student during her master’s and doctoral program and interviews with 3 mentors, 2 peers, and 2 community partners, as well as observations and documents. A constant comparison analysis …

Yon, Jason Kaiser, John S. Maclean

The Compass: Earth Science Journal of Sigma Gamma Epsilon

The Indian Peak-Caliente Caldera Complex, or IPCCC, is an ideal site to study how large-scale tectonic forces can influence mineralogy on a local scale. This research was completed and compiled by the Tectonics and Mineralogy classes at Southern Utah University during a joint class field study and subsequent laboratory analyses. During the field trip, the main focuses were to observe caldera collapse relationships and ignimbrite features and to collect samples at Condor Canyon and English Canyon, two sites near the border between Nevada and Utah within the IPCCC. After the field trip, the Tectonics class completed a detailed literature review …

Coal Clinker Site In The Late Cretaceous Blackhawk Formation, Castle Gate, Utah, Usa, Robert L. Eves, Larry E. Davis

The Compass: Earth Science Journal of Sigma Gamma Epsilon

When sedimentary host rock is heated as a result of coal seam fires, the host rock is pyro-metamorphosed (high temperature/ low pressure) resulting in the formation of paralava, a low-grade metamorphic rock formed adjacent to coal seams. This paper describes an outcrop locality of clinker (paralava) in the Upper Cretaceous Blackhawk Formation within the Book Cliffs coalfields of central Utah, which formed as the result of a coal seam fire.

Tunneling Anisotropic Magnetoresistance In A Magnetic Tunnel Junction With Half-Metallic Electrodes, John D. Burton, Evgeny Y. Tsymbal

Evgeny Tsymbal Publications

Tunneling anisotropic magnetoresistance (TAMR) is the difference in resistance of a magnetic tunnel junction due to a change in magnetization direction of one or both magnetic electrodes with respect to the flow of current. We present the results of first-principles density functional calculations of the TAMR effect in magnetic tunnel junctions with La_0.7Sr_0.3MnO₃ (LSMO) electrodes and a SrTiO₃ (STO) tunneling barrier. We find an ∼500% difference in resistance between magnetization in the plane and out of the plane. This large TAMR effect originates from the half-metallic nature of LSMO: When magnetization is out of …

Studies report that football players have high blood pressure (BP) and increased cardiovascular risk. There are over 70,000 NCAA football players and 450 Division III schools sponsor football programs, yet limited research exists on vascular health of athletes. This study aimed to compare vascular and cardiovascular health measures between football players and nonathlete controls. Twenty-three athletes and 19 nonathletes participated. Vascular health measures included flow-mediated dilation (FMD) and carotid artery intima-media thickness (IMT). Cardiovascular measures included clinic and 24 hr BP levels, body composition, VO2 max, and fasting glucose/cholesterol levels. Compared to controls, football players had a worse vascular and …

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 …

Data collected includes information on the amount of deer hunted, the number of car accidents, and the number of hunting permits issued. This paper also involves a county level analysis within New York State of 56 counties from 2007 - 2012. An important part of analysis of this paper is the examination of the Buck population vs. the Doe population on the number of car accidents. This is an important study because of its possible policy implications regarding the …

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

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.

Who Cares About The Environment? A Study Of Environmental Behavior In Maine, Chandler L. Blake

Journal of Environmental and Resource Economics at Colby

Identifying and targeting environmentally minded people is crucial to making any environmental campaign successful. It allows you to advertise to the people who will be the most helpful and supportive to your cause. The goal of this study is to identify the general demographics of environmentally minded people. To do this I examine voting data through each county in Maine and run a regression to test whether income, education level, and household size have any correlation to how the county votes on environmental issues. I found that the higher a county’s income, the more environmentally friendly their voting. I also …

Analyzing Consumers’ Willingness To Pay For Eco-Labeled Seafood Products In Coastal And Inland Maine Counties, Gaby E. Carpenter

Journal of Environmental and Resource Economics at Colby

Around the world, green labels are used for a wide range of food products, both in grocery stores and restaurants. Often, the price for these labeled products is higher due to higher production costs associated with the goods. This leads to demand for these goods in the market and consumers that are willing to pay. Here, I will examine the willingness to pay for three different eco-labeled seafood dishes at a Maine restaurant using a consumer choice experiment survey. I will use this survey to conduct a benefits transfer analysis to approximate the willingness to pay of consumers in each …

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

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 …

Renewable Energy Consumption: Initiatives In Colorado And Washington, Robin K. Doroff

Journal of Environmental and Resource Economics at Colby

This paper examines the use of policy mechanisms to increase renewable energy consumption within the United States. In order to effectively measure the change of renewable energy consumption, I analyze two initiatives that promote energy consumption from renewable sources and overall increases in energy conservation. Colorado and Washington had approved initiatives in the years 2004 and 2006, respectively. Although the results are not entirely statistically significant, I find that the initiatives lead to increases in total renewable energy consumption and decreases in total energy use.

Stock Market Reactions To The Iarc Announcement Linking Red Meat And Processed Meat To Cancer, Scott B. Lehman

Journal of Environmental and Resource Economics at Colby

This study investigates how food companies were affected by the International Agency for Research on Cancer’s report that linked processed meat and red meat consumption to increased risk of cancer. The results indicate that neither fast food companies nor meat producers were greatly affected by the announcement in the days immediately following the release.

Property Value Changes From Public Transportation: How The Greenbush Commuter Line Affected Property Values, Sarah C. Evans

Journal of Environmental and Resource Economics at Colby

Prior studies have investigated the impact on property values to the proximity of established public transportation stations. Public transportation is thought to increase value of towns and properties, giving residents more options for transportation to and around the city. Both benefits and consequences of public transportation exist, allowing for either a raise or lower of property values in towns with stops. This paper analyzes the Greenbush Commuter line in Massachusetts, seeing if the proximity to the stops has an affect on the property of values in the towns. A difference – in – difference model is used to investigate a …

The Effectiveness Of The Colby College Electricity Competition On Promoting Electricity Conservation To Students, Jeff Vaz

Journal of Environmental and Resource Economics at Colby

This paper examines the effectiveness of the Colby College electricity reduction competition in altering students’ behavior to conserve electricity. The Colby College electricity reduction competition is an information-based policy that Colby implemented to promote the conservation of electricity, which are a major contributor to greenhouse gas (GHG) emissions in the United States. The study analyzes if different residence halls reduce electricity consumption by different amounts during the competition period. Results indicate that only 4 of 22 residence halls reduced electricity usage during competition periods in a statistically significant manner. The study concludes that the electricity competition at Colby College is …

In Equations We Trust? Formula Learning Effects On The Exponential Growth Bias, Bryan Foltice, Thomas Langer

Scholarship and Professional Work - Business

This paper evaluates the possible benefits and drawbacks of the formal formula learning of compound growth as it pertains to eliminating, or at least reducing, the exponential growth bias in various household savings and debt decisions. In our main experimental study, we determine if the ability to calculate the simple compound savings formula only assists in its direct area of application with an available calculator, or if this knowledge extends into similar exponentially-based savings and debt decisions when either a calculator is prohibited or when the formula is unknown. In the process of tackling this research question, we develop a …

Toward Improving The Learning Process, Alexander T. Wells

Bollinger-Rosado Teaching & Learning Effectiveness Symposium Proceedings

Brilliant, motivated students are fun to teach. They love to work, want more of it, and sometimes even overwhelm you with their enthusiasm for learning. But today's classes are not overcrowded with such paragons. Often unmotivated or distracted students, who don't learn even when we are at our scintillating best, sit in our classes. Professors may exhort them to try harder, but if exhortation fails, what can lead to success?
