Biomass Cookstoves: An Empirical Study Into The Relationship Between Thermal Efficiency And Tending Practices For The Developing World, Erin Peiffer

Honors Theses

More than 2 billion people in the world use biomass stoves for cooking and heating their homes. Due to incomplete combustion, toxic byproducts such as soot, nitrous oxides and carbon monoxide gasses form. These toxic substances contribute to pollution and can lead to serious health issues over time if inhaled leading to approximately 4 million premature deaths each year. The formation of these toxic substances can be mitigated, in part, through the introduction of increased turbulence intensity allowing for the so-called “well-stirred combustion regime”. Here we will be exploring the health, environmental, and social effects of biomass combustion in the …

Evaluation Of Protection Of Frp Wrap On Bridge Piers From Corrosive Effects Of Snow And Ice Chemicals, Lizzie Miller

Honors Theses

Highway bridge components, such as decks and piers, are structures that are often exposed to chlorine-heavy chemicals. Corrosion of rebar, one of the main contributors to structural deficiencies in highway bridges, is largely caused by chloride contamination from exposure to deicing salts and chemicals. Current forms of external protection to highway bridge piers include paint coatings, shells, and wraps. This thesis will focus on the protective capabilities that Fiber Reinforced Polymer (FRP) wraps could provide to bridge piers. ASTM C666 was utilized to recreate environmental conditions, during which concrete samples were exposed to calcium chloride. ASTM C1760-12 was utilized to …

You Have The Right To…What? A Study Of Knowledge Of Americans’ Rights In Criminal Proceedings, Anna Marchiony

Honors Theses

An exploratory questionnaire was developed to assess participants’ knowledge of American rights during criminal proceedings, their confidence in that knowledge, and whether their experiences, professional or recreational, are associated with that knowledge. Questionnaire items covered topics such as Bill of Rights, Miranda Rights, Interviews and Interrogations, Rights During Trial, and Post-Conviction Rights. Demographic variables assessed field of study/employment, encounters with the Criminal Justice System, and viewership of crime-based television shows. Responses were analyzed in an attempt to find patterns in knowledge. Results showed that participants were most knowledgeable regarding the Bill of Rights, rights during a criminal trial, and post-conviction …

Accounting For Change: Assessing Top-Line Implications Of New Revenue Recognition Principles, Kevin M. Wargo

Honors Theses

The impending implementation of new FASB guidance regarding the practice of revenue recognition will presumably alter the periodic presentation of top-line business performance. In anticipation of these impacts, this study seeks to isolate contractual business relationships within the automotive supply chain industry in order to illuminate certain changes and make financial statement users aware that corresponding adjustments may have to be made to their perception of revenue results. By outlining the differences between new and historical U.S. GAAP, and applying the anticipated quantitative effects of such shifts within a propositional study, I seek to produce conclusions that investors and analysts …

Does Riparian Forest Invasion By The Exotic Shrub Amur Honeysuckle Influence Nutrient Dynamics In Headwater Streams?, Charlotte Anne Shade

Honors Theses

Lonicera maackii (Amur honeysuckle) invasion is extensive in forests across much of Ohio and the Midwest. Amur honeysuckle has been shown to influence headwater streams and its organisms, which depend on a certain water chemistry to survive. Little has been done to understand how honeysuckle affects water chemistry and nutrient cycling. As honeysuckle canopies prevent native organic matter from entering the streams below, while also adding its own organic matter that is high in nitrogen and phosphorus, and low in lignin, the amount and types of nutrients present in both forests and streams may be significantly altered. Over a one-year …

Self Management: Overcoming Barriers To Success, Jazmyn Souryamat

Honors Theses

Individuals with an autism spectrum diagnosis often have a social-skills deficit that may include the tendency to avoid eye contact. In addition, they may have sensory issues and become easily overwhelmed by excessive sensory stimuli. Self-management is a treatment that has been found to enhance the quality of life for individuals with or without an autism spectrum diagnosis. It has been helpful in treating procrastination, used to increase physical activity, lower caloric intake, and increase independence. In this study, self-management treatments were used to increase instances of appropriate social responding and to decrease behaviors that posed a barrier to personal, …

Investigating Medicinally Important Portein-Protein And Protein-Ligand Interactions : A Computational Approach, Cooper Ashley Taylor

Honors Theses

Molecular dynamics (MD) simulations and computational chemistry allow for an atomistic understanding of protein-protein and protein-ligand binding motifs. Through the use of MD, medicinally relevant complexes can be examined in detail unattainable by experimental methods. Within this work, systems pertinent to both Alzheimer’s Disease and HIV-1 are probed and thoroughly sampled to help elucidate potential therapeutic pathways. We used molecular dynamics and free energy estimations to gauge the affinity for the binary and ternary complexes of KLC1, APP and JIP1, three proteins all believed to be involved in the propagation of Alzheimer’s Disease. Two areas of thought exist suggesting that …

The College Admissions Problem: Effects Of Income And Ability Of Postsecondary Education Outcomes, Martha Whamond

Honors Theses

This paper examines the effects of students’ pre-college income on student outcomes and college admissions decisions. Under the assumption that colleges maximize utility by maximizing student outcomes, a two-stage regression model for student outcomes is building using data from the Integrated Postsecondary Education Data System (IPEDS) and the 1997 National Youth Longitudinal Survey (NLSY97). The first stage estimates a model for college quality using the IPEDS dataset. The college quality estimates are then used as independent variables in the second stage. The second stage estimates student outcomes as a function of pre- college income, ability, college quality, and demographic characteristics …

Correcting Pedestrian Dead Reckoning With Monte Carlo Localization Boxed For Indoor Navigation, Akira T. Murphy

Honors Theses

Localization of phones is a ubiquitous part of the modern mobile electronics landscape. However, there are many situations where the current method of networked localization fails. A Pedestrian Dead Reckoning System where the location of the user is calculated by counting the steps and direction of the user was implemented as an iOS app with python for data analysis. A novel algorithm for wireless sensor localization using Ad-Hoc Bluetooth networks was proposed. A small experiment was performed proving that the system is nearly equal to state of the art algorithms.

Dear Reader, How Do We Go On? Letters Of Reflection On Community Care In Climate Activism In Maine, Ester Topolarova

Honors Theses

Climate activist groups in Maine often see their members become too tired to continue organizing. Thus, I decided to explore how these activists enact community care. I conducted my fieldwork with 350 Maine and its local nodes. I explore community care as a practice and as an aspiration. Community care is practiced through the acts of people taking care of each other. Aspiration, therefore, is a way of living and seeing the self as striving to replicate the world activists are fighting for. I conceptualize care as racialized, gendered, classed, and embedded in neoliberal capitalism. In activist meetings, care is …

I Remember It Like This: Essays, Robin C. Lewis

Honors Theses

This thesis is composed of eleven personal essays. As an Environmental Policy senior, I wanted to write down some of my formative stories—not just any stories, but those that may reveal the environmental thread in my life, which, I believe, was somehow instilled in me by my parents. This thread has followed me from Texas to Maine, from childhood to almost twenty-three. It has been supported and tested by various characters along the way, sometimes growing faint, other times stronger. As I prepare for something new, I’ve found it valuable to look back on the people and landscapes and stories …

Photochemical Generation Of Carbenes And Ketenes From Phenanthrene-Based Precursors Part I: Dimethylalkylidene Part Ii: Diphenylketene, Tarini S. Hardikar, Tarini Hardikar

Honors Theses

Previous studies have shown that the photolysis of phenanthrene-based cyclopropyl precursors can generate carbenes. In this work, a novel phenanthrene precursor was synthesized and photolyzed to generate the dimethylalkylidene carbene, which was subsequently trapped by cyclohexene. The car- bene was not prone to an internal rearrangement as some other carbenes are, and instead favored the intermolecular addition reaction. The precursor also underwent a rearrangement via pericyclic processes. A theoretical analysis of the potential energy surface of the system is presented using coupled cluster and density functional methods. Preliminary analysis for the precursor via time-resolved laser flash photolysis (LFP) was performed. …

A Novel Method For Determination Of Ammonium Isotope Ratios With Electrospray Ionization Mass Spectrometry, Rebecca J. Chmiel

Honors Theses

Nitrogen (¹⁵N) isotope tracer studies are an invaluable tool for understanding the rate of N transformations in the environment. A mechanistic understanding of N cycling is critical to management of excess N availability in freshwater and marine ecosystems. Conventional methods for measuring ¹⁵N:¹⁴N of dissolved inorganic nitrogen species are time consuming and require large sample volumes. Here, we present a technique for measuring ¹⁵N:¹⁴N in ammonium (NH₄⁺) using electrospray ionization mass spectrometry (ESI-MS). NH₄⁺ present in small volumes of sample (3 ml) is complexed with phenol via …

An Alternative Approach To Training Sequence-To-Sequence Model For Machine Translation, Vivek Sah

Honors Theses

Machine translation is a widely researched topic in the field of Natural Language Processing and most recently, neural network models have been shown to be very effective at this task. The model, called sequence-to-sequence model, learns to map an input sequence in one language to a vector of fixed dimensionality and then map that vector to an output sequence in another language without any human intervention provided that there is enough training data. Focusing on English-French translation, in this paper, I present a way to simplify the learning process by replacing English input sentences by word-by-word translation of those sentences. …

Trump, Twitter And The Death Of The American Political Party: A Discussion Of The Fate Of The American Party System Before, During, And After The Presidential Election Of 2016, Madeleine Neider

Honors Theses

Abstract: This paper seeks to address the essential question: what happened during the presidential election of 2016 and what does this mean for the American party system? Using qualitative and quantitative analysis, this research suggests that the 2016 election is evidence that domineering policy demanders, such as the Tea Party Movement and Occupy Wall Street, and domineering politicians, such as Donald Trump and Bernie Sanders, used the democratized media to force a top-down realignment of the American party system. A top-down realignment is characterized by the demise of the prominent American political party­– an institution fundamental to our political process. …

Failure Or Adjustment?: An Analysis Of The Slowing Growth Of The Chinese Economy, Kay G. Degraw

Honors Theses

With GDP growth for the 2016 fiscal year reported at 6.7%, it appears that the Chinese economy has departed from the three-decade period in which GDP growth averaged plus-10%. While both academic journals and media outlets have accredited this slowdown to a variety of factors, existing research has failed to conflate the economic and political factors into a comprehensive explanation. Consequently, this thesis examines the causative factors behind the slowing of the Chinese economy though the analysis of three contesting plausibility probes centered on the impact of corruption, statism, and structural economic change. The results of the plausibility probes indicates …

It’S Not You, It’S— Hookup Culture And Sexual Subjectivity, Anne Vetter

Honors Theses

A semi-fictionalized ethnography that interrogates how students at Colby College use hookup culture as a way to make sense of themselves and others. This thesis is about systems, about social power and norms, and the very real ways that they are experienced in and enacted by the bodies of individual students. In other words, this thesis is a naming of what many students on this campus already know without words, a linking of story to story to story, a marking of patterns that underlie the forms of sexual subjectivity driving participation in hookup culture. Ultimately, by making visible the systems …

The Anonymous Truth: Honesty And Hostility In Public And Private Online Settings, Grace S. Carroll

Honors Theses

Three studies were conducted to understand the relationship between honesty and hostility in public and private online settings. Study one analyzed a college’s public and private online forums and examined post frequency. Related to study one, study two examined the usage of these forums, and current and past social and political issues. Study one found the public forum comprised of general announcements, while the private forum hosted random jokes/statements, negative posts targeting specific people, and personal reflections. Study two’s results indicated the private forum was used more often than the public forum and race was the prevailing social and political …

America's National Parks And The Anthropocene: Addressing The Present To Accommodate The Future In Acadia National Park, Sophie A. Swetz

Honors Theses

In 2000, atmospheric chemist, Paul J. Crutzen, and limnologist, Eugene Stoermer, formally proposed the idea of “the Anthropocene,” a new geologic epoch in which humans are the dominant force shaping the Earth. To claim the Anthropocene's existence is to declare that human actions have altered the Earth in such a way that geologic indicators render it a distinct epoch in the stratification of geologic time. This new epoch emerges as a consequence of increased technological development employed to accommodate an anthropocentric human existence. That is, rapid advancements in technology have driven the transformation from a primarily naturally controlled planet to …

Violence And Edification In 19th Century Fiction: An Analysis Of The Novels Of Charles Dickens And Leo Tolstoy, Caroline Fassett

Honors Theses

This Thesis argues that violence is essential to the structures and plots of Charles Dickens’s Barnaby Rudge and A Tale of Two Cities and of Leo Tolstoy’s War and Peace and Anna Karenina, and is particularly essential to the edification, or the moral and intellectual improvement, of principal characters in these four novels. Additionally, this Thesis contends that this edification is both anticipated and reinforced by the novelists’ incorporation of counterparts whose demeanor and/or narrative overtly mirror that of the principal characters.

To support this argument, I bring the theory of Thomas Carlyle into conversation with the novels of Dickens …

Nature And Human Flourishing In The Laws Of Manu And The Daodejing, Qijing Zheng

Honors Theses

By comparing the interpretation of dharma in the ancient Indian Laws of Manu (Manusmṛti) with the concepts of dao in the Chinese classic, Daodejing, this thesis discusses that, despite the plausible perception that the former represents despotic, hierarchical governance while the latter promotes freedom (and even anarchy), the two texts in fact share a similar envision of human flourishing through the following of one's nature, as well as a foundational belief that both laws and political ideals emerge from nature.

When Worlds Collide: Feminism, Conservatism And Twentieth Century Authors, Madison Cooney

Honors Theses

Two streams of literary narratives appearing during the Great Depression grew from personal and historical experiences of their women authors with overlapping but very different perspectives on American cultural history. These were: 1) The accounts of rural frontier Midwestern regional experiences of Laura Ingalls Wilder, as edited and shaped in part by her daughter and writing partner Rose Wilder Lane, in retrospect during the New Deal era; and 2) the 1920s urban African-American experience of Zora Neale Hurston in the context of an emerging national black artistic and intellectual scene. Through a shared feminism emphasizing freedom for women, these authors …

Dewey's Democratic Economy: A Pragmatic Justification For Uber, Christopher Nard

Honors Theses

This thesis investigates the changing regulatory environment around the ride-sharing platform, Uber. As Uber continues to expand, it poses a challenge for existing regulatory systems. This thesis offers a policy recommendation for regulatory agencies under the framework of a Deweyan Democratic Economy. Research was conducted in the three steps: a literature review; quantitative analysis of Uber's wage, demographic, and surge pricing data; and a series of interviews with Uber drivers, consumers, and policy experts. In the literature review, it was found that a company could move towards a more democratic economy by increasing public access to information and economic participation. …

The Effect Of Font Type On Memory For Instruction, Courtney Upchurch

Honors Theses

The purpose of the present study was to determine whether or not one font type promotes superior memory retention for order over another. Participants were presented with one of three sets of instructions each displayed using a different style of font. They were asked to read the instructions and, following this, were provided with the instructions presented in a different, random order. Their task was to place the instructions back in the order in which they were originally presented. Results indicated that one font style led to better memory for order than the others. In addition, based on participant self-reports, …

Development Of Standard Operating Procedure: Admicellar Polymerization Of Polystyrene Thin Film (Aibn) On Polysciences 30-50Μm Glass Beads Using Cetyltrimethyl-Ammonium Bromide Surfactant, David Langford

Honors Theses

Poly(1-phenylethene), commonly referred to as Polystyrene, is one of the world's most common polymers. Made from the monomer styrene (ethenylbenzene), this polymer is used in a wide range of products from packing peanuts to disposable cutlery. The method of polymerization used in this research project is called admicellar polymerization. This process consists of four main steps: admicelle formation, adsolubilization, polymerization, and removal of admicelle and polymer. Admicellar polymerization has a number of advantages over related methods of thin film polymerization including simplicity and low cost of components and process.
