Influence Of Juvenile Hormone On Territorial And Aggressive Behavior In The Painted Lady (Vanessa Cardui) And Eastern Black Swallowtail (Papilio Polyxenes), Tara Bergin
Honors Theses
Competition is important in environments with limited resources. Males of many insect species are territorial and will defend resources, such as a food source or egg-laying site, against intruders, or even compete to attract a mate. In insects, evidence suggests that juvenile hormone acts as an aggression mediator, much like testosterone in other animal species. In this study I tested this idea using a group of male Painted Lady butterflies, Vanessa cardui, and Eastern Black Swallowtail butterflies, Papilio polyxenes, that were treated prior to metamorphosis with either a high or low dose of methoprene acid (a juvenile hormone mimic). Male-male …
Hearing Arnold In A New Space : Building A Transformational-Theory Patrimony, Whitney Simmonds
Hearing Arnold In A New Space : Building A Transformational-Theory Patrimony, Whitney Simmonds
Honors Theses
The old song goes "you always hurt the one you love", Harold Bloom's The Anxiety of Influence takes that idea a step further: for Bloom, artistic creation is born from an anxiety that compels artists to rebel against the influences of their predecessors, their artistic fathers: one has to metaphorically kill the thing one loves in order to escape its shadow. I realize that in order to do an honors thesis, I have to do a bit of good natured killing of my own - or at least do some sharp elbow jabbing - if only for a moment, to …
Immunological Effects Of Written Disclosure In Athletes, Kristen Thatcher
Immunological Effects Of Written Disclosure In Athletes, Kristen Thatcher
Honors Theses
Many studies have demonstrated the health benefits of written disclosure of traumatic or stressful events. These benefits include improved psychological well-being, fewer health clinic visits, shorter hospital stays after surgery, and increased immune function. In athletes, high immune function is necessary to ward off illness during training and competition, but much research has shown that athletes tend to have lowered immune function. Therefore, writing about traumatic events may be a way for athletes to remain healthy during their seasons. To test this hypothesis, 21 varsity athletes and 15 individuals who exercised less than three hours per week participated in the …
Divergent Effect Of Social Cohesion On Economic Growth In East Asia And Latin America, Horacio Diaz Adda
Divergent Effect Of Social Cohesion On Economic Growth In East Asia And Latin America, Horacio Diaz Adda
Honors Theses
In this paper I explore the link between social cohesion and economic growth in Latin America and East Asia. Unlike previous studies, I allow for different slope parameters for the different regions. Using ethno linguistic fractionalization as a proxy, I find that social cohesion has not played an important role in determining growth outcomes in Latin America. While social cohesion has not had a direct effect on growth nor institutions in Latin America, it helps explain a large degree of the growth differentials among Asian countries. Social cohesion mostly impacts growth through its effect on institutional quality. However, these results …
Two Essays In The Indiana Family Cap Provision, Aimee Williams
Two Essays In The Indiana Family Cap Provision, Aimee Williams
Honors Theses
The first federal welfare program in the United States was established under the 1935 Social Security Act. The child welfare component of this bill was entitled Aid to Dependent Children (ADC). While only children were eligible to receive benefits, this program was partially intended to keep women out of the labor force during the depression so they would not take jobs that would otherwise go to men. In the 1950's and 1960's. this program was expanded to allow states to claim federal reimbursement for aid to unemployed parents and the spouse of an unemployed or incapacitated parent, becoming Aid to …
Voices Of The Poor: Poverty And Growth In Albania, Magda Tsaneva
Voices Of The Poor: Poverty And Growth In Albania, Magda Tsaneva
Honors Theses
This paper uses three waves of panel surveys at the household level to study growth and poverty in Albania over the period 2002-2004. It attempts to answer two main questions. The first question is directed at finding the micro determinants of growth and aims to expose the obstacles households face to improve their economic situation. The main focus of the analysis is to investigate the importance of health, education, and infrastructure indicators for income growth. The second question asks whether growth in Albania during the period 20022004 has been pro-poor. I find that there is some evidence for a convergence …
Concomitant Polymorphism In 1,2-Bis(9-Anthryl)Acetylene, Rebecca Goldstein
Concomitant Polymorphism In 1,2-Bis(9-Anthryl)Acetylene, Rebecca Goldstein
Honors Theses
This thesis details the serendipitous discovery of the phenomenon of concomitant conformational polymorphism found to exist in 1,2-bis(9-anthryl)acerylene. 1,2-bis(9anthryl)acetylene is a previously published molecule. However, the published crystal structure showed the molecule to be completely planar, and to crystallize in the form of orange needles. While this form of the crystal was indeed found during the synthesis of 1,2-bis(9anthryl)acetylene, a new polymorph, crystallizing as yellow prisms, was also discovered. This yellow polymorph was found by X-ray crystallography to be monoclinic with an angle of 66.7 between the anthracene planes. The planar polymorph 1,2-bis(9-anthryl)acetylene was also found by X-ray crystallography to …
Anhedonia And Depression: Anticipatory, Consummatory, And Recall Deficits, Kaitlin Hanley
Anhedonia And Depression: Anticipatory, Consummatory, And Recall Deficits, Kaitlin Hanley
Honors Theses
Current conceptions of anhedonia as a key symptom of depression do not consider the importance of anticipatory, consummatory, and recall deficits involved in anhedonia. Sixty-one depressed and non-depressed, college-student participants provided reports of anticipated pleasure to tasting chocolates, tasted chocolates and rated their experience of pleasure, and provided recalled reports of pleasure to the experience one day later. Results demonstrated a deficit in the ability to anticipate experiencing pleasure for depressed participants when compared to non-depressed controls, however, their reports of consummatory pleasure and recalled pleasure did not differ significantly from non-depressed control participants. This study suggests that actual experiential …
Rawls And Health Care, Elizabeth H. Coogan
Rawls And Health Care, Elizabeth H. Coogan
Honors Theses
John Rawls’s A Theory of Justice (1971), his first major work articulating his theory of justice as fairness, was immediately recognized as a fundamental contribution to political philosophy in the twentieth century. Working within the tradition established by previous philosophers such as Kant and Locke, Rawls employed the contract theory approach. Taking it to a higher order of abstraction, he sought to determine not what the structure of social organization would be, but what the principles which governed social institutions would be under a hypothetical contracting situation. Rawls uses this contract theory approach to construct a society in which the …
Pov-It: The Pov-Ray Interactive Tutorial, Eleanor O'Rourke
Pov-It: The Pov-Ray Interactive Tutorial, Eleanor O'Rourke
Honors Theses
The Persistence of Vision Ray Tracer, commonly known as POV-Ray, is a computer graphics package that can be used to produce highly sophisticated and photorealistic images and animations. POV-Ray is widely used in the computer graphics community for a diverse variety of applications, including teaching college courses, creating visual music animations, and generating computer art. Although the popularity of POV-Ray is apparent, the teaching materials available for the package are confusing, disorganized, and inaccessible. In this project, I have designed an online system that provides a series of interactive tutorials that teach users how to create images using the POV-Ray …
External Control Of Electron Temperature In Ultra-Cold Plasmas, Roy O. Wilson
External Control Of Electron Temperature In Ultra-Cold Plasmas, Roy O. Wilson
Honors Theses
This thesis discusses progress towards achieving external control of the electron temperature and the Coulomb coupling parameter of ultra-cold plasmas. Using a Littman dye laser, we create the plasma by partially photoionizing a dense, cold sample of rubidium atoms in a magneto-optical trap (MOT). At a controllable time delay, we excite neutral atoms in the plasma to a specific Rydberg state using a narrow bandwidth pulsed dye laser. We have made progress towards optimizing and quantifying the achievable Rydberg atom density by using mm-wave spectroscopy to control the evolution of a cold dense Rydberg sample to plasma and have also …
Detailed Mechanistic And Optimization Of The Photochemical Production Method Of Superoxide, Ta-Chung Ong
Detailed Mechanistic And Optimization Of The Photochemical Production Method Of Superoxide, Ta-Chung Ong
Honors Theses
The highly reactive nature of superoxide anion presents an analytical challenge to prepare stable standards for instrument calibration. McDowell et al. (1983) developed a convenient method of superoxide production based on continuous photolysis of benzophenone and acetone in oxygen saturated, alkaline, 2-propanol solution. In the McDowell reaction, ketones are photolyzed to their triplet state, and then reacted with alcohol to produce ketyl radicals that react with oxygen to produce superoxide. This study investigated the mechanism and rate of these reactions by Laser Flash Photolysis (LFP). Reaction rate constants for the reaction between the benzophenone triplet and ethanol was 5.5 x …
Intramolecular Chemistry Of Ss-Acetoxyethylidene And Photochemical Generation Of Vinylidenes, Jennifer M. Nguyen
Intramolecular Chemistry Of Ss-Acetoxyethylidene And Photochemical Generation Of Vinylidenes, Jennifer M. Nguyen
Honors Theses
The parent carbene ß-acetoxyethylidene has been previously generated by the photolysis of its precursor, acetic acid 1a,9b-dihydro-1H-cyclopropa[l]phenanthren-1-yl methyl ester. Mechanistic studies on ß-acetoxyethylidene have indicated the possibilities of three rearrangement pathways to the formation of vinyl acetate: a proton shift, an acyl shift, and a cyclic rearrangement (see Figure 8). A deuterium labeling study involving the replacement of the hydrogens on the methylene carbon has indicated that the simple 1,2-H shift was the primary manner of rearrangement, with an 82% yield of product. However, a primary kinetic isotope effect may have occurred due to the greater strength of a C-D …
Gauguin : Generating Art Using Genetic Algorithms & User Input Naturally, Thomas E. Cook
Gauguin : Generating Art Using Genetic Algorithms & User Input Naturally, Thomas E. Cook
Honors Theses
This paper outlines an undergraduate research project demonstrating an application of evolutionary computation in the context of computer art. The project, named GAUGUIN, combines the visual impact of modern computer graphics with the computational power of genetic algorithms. GAUGUIN allows the user to become a creator of art, without requiring any technical or artistic training. By using an intuitive and easily comprehensible process like evolution to create the composition, the user simply needs to evaluate a sequence of compositions. Mimicking the biological process of evolution, the system will evolve the works in order to achieve images that are more visually …
Photojournalistic Manipulations Of Reality: The Power Over Knowledge, Valerie Friedman
Photojournalistic Manipulations Of Reality: The Power Over Knowledge, Valerie Friedman
Honors Theses
This project is an anthropological study on how students at Colby College interpret photojournalistic images and news media. Using extensive literature, I strove to find a better understanding of how news agencies and the media control the flow and availability of information. Through fieldwork and numerous research methods, I wanted to understand how students formed relationships with images and news stories they encountered. This paper shows how the media and images people see in the news controls the minds and ideas of the public. Newspapers, magazines, the radio, internet sites, television broadcasts, and other forms of news media are primary …
Too Many Bad Cooks Spoiling The Broth? Effectiveness Of Ngos In Addressing Child Labour In El Salvador, Ivica Petríková
Too Many Bad Cooks Spoiling The Broth? Effectiveness Of Ngos In Addressing Child Labour In El Salvador, Ivica Petríková
Honors Theses
The reaction of the first world to the persevering plight of a large part of the third world varies. In response to the sometimes glaring disparities, many international organizations and multinational corporations have recently adopted a pro-development rhetoric with relation to the problem of global poverty. However, the rhetoric rarely translates into action. As David Bacon discusses, leaders of corporations and organizations now tend to conclude their speeches by expressing a desire to reduce the suffering of the third world. However, when it comes to agreeing on specific concessions that could indeed improve the world-wide economic situation, first world countries …
Where Did All These Books Come From? The Publishing Industry And American Intellectual Life, Maro N. Asadoorian
Where Did All These Books Come From? The Publishing Industry And American Intellectual Life, Maro N. Asadoorian
Honors Theses
The American book publishing industry shapes the character of American intellectual life. While the newspaper and television industries have been accused of and investigated for bias and lowering America’s intellectual standards, book publishing has gone largely unexamined by scholars. The existing studies of the publishing industry have focused on finance, procedure and history. “There are few ‘theories’ of publishing – efforts to understand the ‘whys’ as well as the ‘hows.’ Few scholarly scientists have devoted significant scholarly attention to publishing” (Altbach and Hoshino, xiii). There are many possible reasons for this lacuna. First, there is a perception that books have …
World Bank -Cpa Conflict: The Struggle To Define Human Rights And Development In The Philippines, Adam B. Robbins
World Bank -Cpa Conflict: The Struggle To Define Human Rights And Development In The Philippines, Adam B. Robbins
Honors Theses
This thesis analyzes the interactions between the World Bank (hereafter, the Bank) and the Cordillera Peoples Alliance (CPA), an indigenous and environmental advocacy group based in the Cordillera region of Luzon, in the Philippines. Using data gathered through both text-based and participatory research methods, I analyze the discursive relationship and violent confrontations between the two organizations. Conflicting development and human rights values cause the majority of these conflicts. I focus on how each organization enacts development and human rights, and how this leads to conflict. Ultimately, I intend for this thesis to offer practical guidance for the reader involved in …
Developing A Tool To Assess Human Health Impacts Of Purchasing, Kaitlin C. Himmelmann
Developing A Tool To Assess Human Health Impacts Of Purchasing, Kaitlin C. Himmelmann
Honors Theses
Chemical production impacts the environment and human health. Many common products contain chemicals that can be detrimental to human health and more specifically harmful to the endocrine system. Many individuals and institutions unknowingly buy products containing chemicals that can harm the endocrine system. I developed a score that examines the level of harm that these chemicals pose to the endocrine health of the general population. The implications of Colby’s purchasing practices are discussed.
