Abigail Adams '04 Georgia Nigro, Psychology Case Study on Autism I am presently completing my service learning at the
Tahsin Alam '04 Áslaug Ásgeirsdóttir, Political Science Microcredit as a System for Poverty Alleviation My presentation is a combination of my research work done on my independent study and senior thesis on the Grameen Bank. The bank has used the process of giving collateral-free loans to the destitute poor to encourage a practice of self-sustenance and the rise out of poverty. I have done extensive research at the Grameen Bank in

Lynne Antinarelli '04 Amy Bradfield, Psychology What’s on Your Warm-Up Mix? There have been many studies that look at the effects of music on tasks. Previous research has found music to have an effect on mood, arousal, and spatial tasks. This study looks at the effects of music on athletic performance among forty-eight varsity athletes from
Christina Austin '05 and Caitlin Vincent '05 T. Glen Lawson, Chemistry The Effect of Caffeine on DNA Repair Caffeine has been identified among DNA repair inhibition agents as an enhancer of radiation toxicity and carcinogens. Our experiment aims to explore the potential inhibitory effects of caffeine on DNA repair, in situations of exposure to the drug both before and after UV irradiation. We sequenced the gene encoding Saccharomyces cerevisiae (baker’s yeast) pyruvate dehydrogenase. Analysis of this gene sequence provides a good idea of inhibition of repair mechanisms by caffeine, since it is certain that the cell will make some effort to repair any damage caused by the UV exposure. We expect that the longer the yeast cells are exposed to caffeine, the more mutations they will have in the gene of interest. We also expect that the yeast culture treated with caffeine post-radiation will have a smaller degree of DNA mutation as compared to the pre-radiation treatments.

Amanda Beck '04 Rebecca Sommer, Biology Cloning and Sequencing of The sympathetic nervous system controls cardiac function in mammals through adrenoreceptors that mediate the physiological effects of the neurotransmitter catecholamines, including epinephrine and norepinephrine, hormones and drugs. At least nine human adrenoreceptor subtypes have been found to exist, including the β-adrenergic receptors that are involved in various central nervous system processes, including learning, memory, adaptation to stress, smooth muscle tone, metabolism, the respiratory system, and the cardiovascular system. Malfunctions in the regulation of the β-adrenergic receptor system have been correlated with the development of depression and other psychiatric and neurodegenerative diseases, asthma, and congestive heart failure. This investigation attempts to clone and sequence both normal and splice variant full-length cDNA for the chick β1 adrenergic receptor. Specifically, the promoter region is targeted through the use of a technique of chromosomal genome walking.
Andrew Beckington '04 Curtis Bohlen, Environmental Studies Regional Conservation Planning: A Balancing Act between Biodiversity and Humans Regional conservation planning is an attempt to balance human needs while still protecting biodiversity on a large scale by designating areas that can be developed for human use and, likewise, areas that need to be preserved for biodiversity conservation. Recently regional conservation planning has begun to take hold throughout the world in the effort to conserve biodiversity. Understanding what regional conservation plans have achieved thus far and how to improve them is important. This study focuses on regional conservation plans in

Erin Bertrand '05 Rachel Austin, Chemistry Mechanistic Inquiries into Environmental Hydrocarbon Degradation by Microbacterial Metalloenzymes A relatively wide variety of bacteria in both the terrestrial and marine environments possesses the ability to degrade hydrocarbons. The magnitude of their role in the global carbon cycle is not, however, well understood. Despite the wide range of bacteria that can accomplish this transformation, only four enzymes are known that can catalyze the oxidation of alkanes. We have developed a method of mechanistic screening to investigate alkane-degrading organisms, entailing the use of diagnostic substrates on whole cells which, once metabolized, can be analyzed to explain the mechanism of metalloenzme function in hydrocarbon degradation, specifically the lifetime of the radical intermediate generated in these processes. Recent experimentation has shown that the method of substrate introduction significantly alters measured radical lifetime, thus calling into question the finer points of this promising whole-cell approach to mechanistic inquires.
Renée Blacken '05 Thomas Tracy, Religion Singing in the For my senior thesis in religion, I have been studying the relationship between music and identity. My focus is on the specific singing practices of the Primitive Baptists in Southern Appalachia and how their style of singing, distinct from other Christian worship singing, reflects the social, cultural, geographical, and theological values of the Primitive Baptist community. I also consider the evolution of the shape-note singing tradition in this region and examine its relationship to Primitive Baptist worship song. A poster offers background information on the history of the music and the theology of the Primitive Baptists, and shape-note and Primitive Baptist songbooks are on display. The presentation includes a performance of shape-note songs and Primitive Baptist hymns by
Renée Blacken '05, Susan French '04, and Lauren Randall '04 Thomas Wenzel, Chemistry Carboxymethylated Cyclodextrins and Their Lanthanide Complexes as Chiral NMR Solvating Agents Cyclodextrins are cyclic oligosaccharides characterized by a tapered, hydrophobic cavity and torus-like structure. They are of particular interest due to their ability to form host-guest inclusion complexes and their potential to serve as chiral solvating agents for enantiomeric substrates. An investigation of the carboxymethylation of hydroxyl groups in alpha, beta, and gamma CD is underway. Several methods of functionalization are being pursued to determine which yields the greatest discrimination of substrate. These include established procedures for the indiscriminate carboxymethylation at the 2-, 4-, and 6-positions, and selective addition of a CM group to the 2- and 6-positions individually. Results from the addition of paramagnetic lanthanide cations to a series of selectively carboxymethylated CDs is expected to induce greater shifts in the NMR spectrum of the guest compound and provide information as to the geometry of association between the substrate and the cavity of the modified CD.
Rachel Booty '04 Beverly Johnson, Geology and Environmental Studies Soil Lead Determinations in Three Urban Elevated lead levels in urban soils are a major source for increased blood lead levels in residents via hand-to-mouth ingestion and dust inhalation. Children are particularly susceptible to the adverse developmental effects associated with high blood lead levels. Lead in urban soils has accumulated significantly during the past century from the use of leaded gasoline, and leaded paint.

Specimens were collected from
Christina Browne '04 Amy Bradfield, Psychology The Effect of Extra-Legal Factors in the Capital Punishment System In my senior thesis in political science and psychology, I examined the influence of extra-legal factors in the capital punishment system. I attempted to address the current lack of research and political theory with the ability to evaluate the intersecting elements of an individual’s identity. I specifically examined how juror perceptions and sentencing of female offenders were affected by the variations of the offenders’ race (black vs. white) and their sexual orientation (homosexual vs. heterosexual).
Mike Buffo '04 Sharon Kinsman, Biology and Environmental Studies Whitebark Pine (Pinus albicaulis) in Whitebark pine (Pinus albicaulis) is a subalpine species native to the western American and Canadian cordillera whose population is declining because of successional replacement by shade-tolerant species, and the exotic fungus white pine blister rust (Cronartium rubicola). Whitebark pine is an important food source for birds and mammals in subalpine forests. The forest structure of three sites in the
Andrew Byrnes '05 and William Fox '05 Matthew Côté, Chemistry The Nanotechnology Project: Electronics Students in Chemistry 199, The Nanotechnology Project, have undertaken the design and construction of a simple, low cost, scanning and tunneling microscope (STM). If successful, the microscope will produce images of the surface of a conductive sample revealing nanometer-scale features. This poster focuses on the electronic aspect of the project. The goal is to design and construct the circuitry needed to control the STM probe’s movement as it scans the sample’s surface. By using a feedback loop to monitor the tunneling current and adjust the microscope tip in relation to the sample, the STM Probe can track nanometer scale features on the sample’s surface. A three-dimensional map of the probe’s path constitutes an image of the sample.
Shoshoni Caine '05 and Jevede Harris '05 T. Glen Lawson, Chemistry The Effects of 8% Ethanol on the Saccharomyces cerevisiae SOD2 Gene The SOD2 gene codes for the SOD2 mRNA, which translates to MnSOD protein. This protein catalyzes the destruction of radioactive oxygen species produced during ethanol stress. Ethanol-stress was found by Alexandre, et. al. (2001) to activate the normally repressed SOD2 gene in Saccharomyces cerevisiae (baker’s yeast). Gene expression was observed after 60 minutes of ethanol exposure, but not after 30 minutes. We will determine a more precise gene activation time during this 30-minute to 60-minute period by exposing yeast grown overnight to 8% ethanol, and using RT-PCR to determine positive gene expression in the cells. Seven treatments will be prepared and exposed to ethanol for 30, 35, 40, 45, 50, 55, and 60 minutes, respectively. We expect that the expression of the SOD2 gene will begin closer to the 60-minute period. In addition, we intend to establish whether the intensity of SOD2 gene expression is time dependent.
Rebecca Castle '04 Amy Bradfield, Psychology The Effect of Suspicion and Photospread Type on Eyewitness Identification False identifications occur with frequency; inaccurate witnesses have the same certainty as accurate witnesses; and sometimes false convictions based on faulty eyewitness accounts have led researchers to search for the best process for making identifications (Wells, 1993). To date, it is the sequential method that is superior in reducing false identifications. The present study questions whether the sequential method is always the superior method. Previous research suggests that if one is suspicious and later has to make an identification, the witness’s accuracy in remembering the suspect increases, despite the identification procedure being used. To test this hypothesis, participants viewed a short, silent video clip (the suspicious half knowing that they will have to later make an identification) and then made an identification of the person in the video on a randomly assigned sequential or simultaneous photospread. No instruction warnings were be provided. This was followed by a brief questionnaire including questions on other variables of interest besides accuracy, such as confidence, ease of identification, their view of the person’s face, their attention, if they would testify, their basis for making an identification, their suspicion, and the clarity of the person’s face in their mind. Results show both suspicion and lineup type have an effect on identification decisions.

Swita Charanasomboon '04 Georgia Nigro, Psychology Relational aggression among Elementary School Girls, an ethnographic study in an After School Program at Lewiston Public Housing Using ethnographic methods including taking field notes and interviewing, I investigated relational aggression that is prevalent among the third and fourth grade girls in the afterschool program. According to previous research, boys tend to physically aggress more than girls, but girls tend to socially aggress more than boys. Since overt aggression as an expression for anger is not encouraged among girls, girls let out their anger in these subtle, but equally hurtful, ways. Relational aggression uses the friendship as a tool to hurt another girl, by threatening the friendship. My field work indicates that social aggression may take the form of socially excluding one girl for the whole day, talking behind one girls’ back, ganging up on one girl to tease her, or threatening to end the friendship to get what one wants. I propose that girls use social aggression to alleviate boredom, seek attention, gain some power, and bond with other girls. An interesting twist to this study is that the subjects are Somali and live in subsidized housing, thus are of a different religion, race, and class than the middle-class Caucasian American girls on whom most of the relational aggression data is based.
Jessica Ciak '05 and Anna Sleeper '05 T. Glen Lawson, Chemistry The Effects of Varying Concentrations and Time Exposure of Arsenite (III) Oxide on the Citric Acid Cycle Through consumption of contaminated water, accidental ingestion, and malicious poisoning, arsenic has been known to cause death at exposure levels as low as 400 μg/L. It exists in various oxidation states, including arsenate [As(V)] and arsenite [As(III)], with arsenite as the more toxic of the two. Arsenite disrupts the sulfhydryl group on lipoic acid, the essential cofactor of the enzyme pyruvate dehydrogenase. Arsenite poisoning is fatal because this enzyme catalyzes the initiation and rate-limiting step of the citric acid cycle. This cycle is crucial for producing ATP, the main energy source for eukaryotes. Our goal is to verify the inhibitory effects of arsenic on pyruvate dehydrogenase and lipoic acid. By comparing arsenite concentration and its exposure time to enzyme inhibition, we hope to determine the relative toxicity. We hypothesize that with increased incubation time and concentrations of arsenite, we will observe a decrease in overall enzymatic activity.
Justin Cidado '04 Paula Schlax, Chemistry Small RNA Molecules and Translational Regulation RpoS is the sigma factor that initiates the general stress response in Escherichia coli (E. coli). Since RpoS is such a vital element to the survival of the bacteria, it is highly regulated through various mechanisms on the transcriptional, translational, and post-translational levels. I have focused on the regulatory effects of small, non-coding RNAs (ncRNAs) on the translation of RpoS by creating a cDNA library of synthetic ncRNAs and determining the effects that each has on the expression of RpoS.

Seamus Collins '04 John Rhodes, Mathematics Mathematical Modeling of Molecular Evolution Over the past thirty years,
Sarah Connell '04 Henry Walker, Classics and Classical and Medieval Studies Hero and Goddess My presentation explores the connections between the ancient Celtic sovereignty goddess figure and the immortal women in the Odyssey, particularly Circe. Medieval Irish texts reflect an ancient Celtic tradition in which a mortal king gained sovereignty by symbolically marrying or sleeping with a supernatural woman who represented the kingship, the otherworld, and the land over which the king reigned. The sovereignty goddess reflects an Indo-European tradition, and she appears in a number of Irish and Welsh texts. She appears in the Irish tale, The Voyage of Máel Dúin, which has a number of structural similarities with the much earlier Odyssey. Circe has a significant number of traits in common with the sovereignty goddess, but the Greek tradition does not have any notion of a man gaining kingship by sleeping with a goddess.

Derek Depelteau '04 and John Sullivan '04 T. Glen Lawson, Chemistry Saccharomyces cerevisiae Cells Transfected with Escherichia coli DnaK, the Hsp70 Homolog, Endure Greater Thermal Stress Given that, (1) Escherichia coli has a higher maximum heat shock protein (Hsp) induction temperature than Saacharomyces cerevisiae, (2) DnaK is a homolog of Hsp70 and (3) many of the cochaperones needed for DnaK function also have eukaryotic homologs, we plan to transfect yeast cells with a plasmid containing the prokaryotic DnaK gene and test the thermotolerance of cells containing the plasmid against yeast cells that do not carry the plasmid. We are interested in determining if the homology between the prokaryotic DnaK and the eukaryotic Hsp70 is sufficient to allow the DnaK chaperones to assist in cytoprotective function. Secondly, if the DnaK plasmid is successfully integrated into the yeast cell and transcribed, we expect that the yeast cells will gain a higher thermotolerance both with and without preconditioning. It is our goal to determine whether a prokaryotic protein that maintains homology with a similar protein in mammals, can in fact be used to strengthen the stress response of another organism.

Dana DiGiando '04 Rachel Austin, Chemistry Comparative Study of Toxic Metals This thesis addresses two case studies of metal toxicity: lead contamination in soils and tributyl tin’s role in the development of reproductive defects in dogwhelks on Bailey Island, Maine. Lead poisoning has been a primary environmental health issue for the past quarter-century and, increasingly, attention has focused on soils as a reservoir for lead. Phytoextraction, or the use of plants to remove contamination, has potential to decrease the amount of lead in soils without great cost or invasive procedures. Spinach has shown promise as a lead accumulator. Besides being inexpensive and non-exotic, when coupled with chelating additives, it has the possibility of being relatively effective. Tributyl tin (TBT) enters the marine environment through its use as an antifouling biocide. TBT causes imposex in female dogwhelks, leading to sterility and possible death. At

Rebecca Dolan '04 Rebecca Fraser-Thill, Psychology Eating Disorder Symptomatology and Reasons for Exercise in College Athletes and Nonathletes This study is designed to replicate and extend a recent study by DiBartolo and Shaffer (2002), which addresses the issue of eating disorder symptomatology and psychological well-being (self-competence and reasons for exercise) in athletes and nonathletes at a small, Division III, all-female liberal arts college. DiBartolo and Shaffer found that overall, the female athletes held healthier attitudes about their bodies, their eating habits, and themselves in general than the female nonathletes. The purpose of the present study was to replicate and extend these findings. The same measures of body image, eating disorder symptomatology, and reasons for exercise were used to assess athletes and nonathletes at
Christina Doukeris '04 Antonio Planchart, Biological Chemistry Assessing Testis Specificity of the TCP 10a-related Sequence of Mouse Chromosome 17 through DNA-Protein Complex Formation This thesis project includes a description of electrophoretic mobility shift assay acrylamide gels to determine DNA protein complex formation for a specific zonucleoticle sequence. Spermatogenesis is the complex, multi-staged process in which mature and functional spermatozoa are produced. During this process, both testis-specific and non-specific genes are transcribed and expressed. Chromosome 17 harbors several testis-specific genes whose expression is believed to be crucial for proper spermatozoa development. Further exploration of the transcriptional regulatory mechanisms of these genes may lead to a greater understanding of their relevance to male fertility. A specific 20 nucleotide region, known as Tcp10a-related sequence (Tcp10Ars), is found upstream of the start site of transcription of both chromosome 17 tcp10a and Tctex1 genes. Allegedly, this sequence is necessary for proper expression of both Tcp10a and Tctex1 during spermatogenesis. Knowledge of the testis-specificity of the Tcp10bt Gene, a gene related to Tcp10a, leads to the hypothesis that the Tcp10ars element is active in regulating the expression of Tcp10a and Tctex1 in the testis. This research attempted to further characterize the Tcp10ars motif for testis-specific protein binding through electrophoretic mobility shift assays using double stranded Tcp10rs radiolabled oligonucleotide. Nuclear protein samples from testis, liver, brain, and NIH 3T3 cells were purified by polyethylenimine extraction protocol. Nuclear extracts were allowed to form complexes with radiolabeled Tcp10ars oligonucleotides and subsequently electrophoresed through non-denaturing polyacrylamide gels. The gels were exposed to image plates and scanned for further analysis of DNA-protein binding. DNA-protein complex formation was observed with nuclear extracts from testis, liver, and brain, as well as testis cytoplasm extracts. No binding was present with the NIH 3T3 protein samples. The observed binding indicates that there are proteins present within some of the tissues that bind Tcp10ars. The present study, however, is not sufficient to conclude that the observed protein binding specifically acts to activate Tcp10a or Tctex1 gene expression. Additional investigations using DNA microarrays, reporter constructs, and Northern blot analysis will be needed to determine if the nuclear proteins are binding to regulate gene expression in the various tissues.

Daisy Fischer '04 T. Glen Lawson, Chemistry Ubiquitination of the Encephalomyocarditis Virus 3C Protease by a Ubc5a-Dependent E3 Ubiquitin-Protein Ligase The encephalomyocarditis virus (EMCV) 3C protease is degraded by the ubiquitin/26S proteasome system. The sequence 34LLVRGRTLVV41 in the 3C protease functions as a signal for recognition by the ubiquitin-protein ligase E3α. While E3α is responsible for the majority of ubiquitin-3C protease conjugate synthesis, extensive mutation of the mapped primary destruction signal does not completely eliminate this ubiquitination. We have demonstrated that a second, Ubc5a-dependent E3 ligase also recognizes the EMCV 3C protease. We attempted to map features of the EMCV 3C protease required for recognition by this second E3. An EMCV 3C protease with an extensively mutated E3α- recognized destruction signal was subjected to further mutagenesis. Evaluations of the mutated proteins, prepared by in vitro translation, revealed that the secondary ubiquitination signal resides in the N-terminal half of the protein. The elimination of the primary signal sequence was shown to completely eliminate ubiquitination. These results suggest that features of the Ubc5a-dependent E3 recognition motif may overlap with those required for recognition by E3α.

Mara Fleischer '04 Kathryn Low, Psychology The Differences in Shoplifting Rates for Eating Disorder Subtypes: Binge Purge, Restrictive Eating, and Control Groups Many research studies have found that shoplifting is often related to certain types of eating disorders. Although these studies suggest a possible association between bulimia nervosa and shoplifting, none of these studies have investigated differences in shoplifting rates for eating disorder subtypes. Therefore, to assess the significance of shoplifting among eating disorder subtypes, 100 participants were asked to complete three anonymous measures that included: a general information sheet, the Eating Disorder Inventory, and a shoplifting measure. Due to recent research, I anticipate finding a significant correlation between binge/purge eating disorders (BNNP, BNP and ANBP) and shoplifting. However I do not expect to find a significant correlation between restrictive eating (ANR) and shoplifting, or a significant correlation between the non-disordered group of individuals and shoplifting.
Jacob Friedman '04 Georgia Nigro, Psychology The Effectiveness of Short-Term Family Mediation at a Local Youth Shelter The New Beginnings shelter provides temporary residence for adolescents aged twelve to seventeen who are homeless, from a troubled family, or in need of emergency shelter. New Beginnings tries in a number of ways to help the adolescents deal with a variety of problems. For those who have familial disputes and issues, New Beginnings offers a mediation program. In this program, a neutral party ensures that both the child and the parents/guardian have an equal chance to speak their mind, and that both sides feel that they are being heard. The goal is to create an environment in which there is a balance of power between the two parties so that all issues are addressed in a calm, productive manner. In this study, the effectiveness of the mediation program was evaluated. Phone interviews were conducted with parents/guardians who had participated in mediation. They were asked a variety of questions concerning the positive and negative qualities of the mediation, and their perception of its short and long term benefits.

Beth Greene '04 Michael Sargent, Psychology The Effect of Gender-Stereotypic Commercials on the Athletic Performance of Female Children Living in a world surrounded by mass media, today’s children are more and more influenced by the images in the environment around them. Looking at television alone, children may be influenced by both the programs and the commercials they watch. Many studies have shown that the content of commercials is gender-biased, with males dominating the screen. One potential consequence is that females may react differently to gender-stereotypic commercials than males, perhaps as a result of stereotype threat activation. This study investigates how gender-stereotypic television commercials may affect the athletic performance of young females. It is expected that participants in the stereotype condition will display high levels of anxiety, which will inhibit athletic performance. On the other hand, participants in the counterstereotype condition are expected to display low levels of anxiety, resulting in better athletic performance than the former group.
Brian Greenleaf '05 and Keith Hengen '06 Matthew Côté, Chemistry The Nanotechnology Project: Mechanical Design A course called The Nanotechnology Project was introduced this year. A small course focused on group thought and cooperative work, its six class members were assigned to research, design, and build a scanning tunneling microscope. An STM is capable of “seeing” atoms at the scale of fractions of a nanometer. In order to expedite the process of construction, the six person class broke into teams of two, each assigned to focus on one of the three areas of STM design: mechanical, electronic, and software. While the three groups worked independently, close communication and collaboration ensured that the final products would combine smoothly. This poster presents the mechanical theory and the process of construction behind STM microscopy, including the specific device produced in class. The main objectives, which our design had to achieve, were coarse and fine positioning and ultra-high positioning stability on the nanometer scale.

Sara Gusky '07 Felicia Fahey, Spanish Seasons of Emotion in Pablo Neruda’s “El barco de los adioses.” Exploring the relationship between identity and culture, the Spanish diaspora focuses on the theme of reinventing one’s identity post-exile or displacement. By evaluating the different aspects of the Spanish diaspora through the literature of the African, indigenous, political, Jewish, and Latin diasporas, this course offers insight into the various emotional standpoints of recreating a native culture outside of the native environment. My presentation highlights the emotional evolution within a mythical space as portrayed in Pablo Neruda’s poem, “El barco de los adioses.” As the imagination’s sacred and protected reserve, the mythical space provides a mental refuge for the displaced. I examine Neruda’s use of the mythical space as an outlet for emotional freedom, which consists of emotional tumult and tranquility. I use Neruda’s seasonal imagery as a metaphor for the seasons of emotions that approach with each stage of the diaspora.
Jennifer Hanley '05 Dolores O’Higgins, Classics and Classical and Medieval Studies The Perversion of Ritual in the Iliad The majority of classics scholars argue that the Iliad only contains instances of positive, ordered ritual. However, in order to justify their theory they blatantly ignore several significant passages within the Iliad that contradict their argument. I disagree with the current view. In my paper, I draw several examples from the text to show that the Iliad reveals the extreme perversion of ritual through its desecration of sacrifice, feasting, and funerary rites. Andrew Hardy '04 Jennifer Koviach, Chemistry Toward a Flexible Synthesis of Polyacetylene Spiroketal Enol Ethers Synthesis of a polyacetylene spiroketal enol ether analog of Tonghaosu, which is found to naturally occur within the genus Chrysanthemum as a secondary metabolite, is begun. The starting material for the synthesis is D-ribofuranose. This method is convenient because of the low number of synthetic steps as opposed to previous syntheses, as well as the option for C6, C7 functionality. The ability to equilibrate diasteriomers following total synthesis of the Polyacetylene spiroketal enol-ether is also discussed.

The term has come to include not only the economic expulsion and massive migration of various groups around the world, but also the study of the development of cultures in a transnational setting. My portion of the panel presentation explores the idea of the natural world as an alternative “home” for people forced from their homeland. The concept that nature supersedes the political boundaries imposed by humans is considered through its representation in various literary works.

Nils Johnson '07 and Jeffrey Woltjen '07 Matthew Côté, Chemistry The Nanotechnology Project: Software Six Bates students enrolled in Chemistry 199, The Nanotechnology Project, knowing nothing about nanotechnology, let alone the components that make up a scanning tunneling microscope. By day three of the class, the students were divided into three groups that would design specific parts of the microscope. Halfway through the semester, the combined efforts of the software, electronics, and mechanics teams yielded a functioning prototype. The cost of the instrument, not including the computer and interface card, was less than $200. The task of the computer software team was to write a LabView program that controls multiple dimensions of the microscope’s motion and displays the nanometer-scale details of what the microscope is viewing. This poster describes the computer software we designed to control the instrument.
Julia Judson-Rea '04 Kimberly Ruffin, English Generating Cross-Cultural Dialogue within Environmental Studies Gary Paul Nabhan writes, “Ever since I worked as a student intern at the first Earth Day’s headquarters in 1970, I have wondered why the so-called Environmental Movement is so clumsy at reaching out to speak to (non-white people)… That gap has shrunk some since 1970, but few folks are content that it has shrunk enough. More than anything else, I want to imagine a dialogue between cultures living in the same homeground.” To help this dialogue take place, we have investigated the role of race and ethnicity in environmental studies discourse, primarily through theory and the cultural production of non-white artists. Our central question has been: how can attention to race and ethnicity intensify cross-cultural dialogue about environmental histories, images, and issues?
Julia Judson-Rea '04 Peter Rogers, Environmental Studies “The Greens Are Back in Town”: Reasons behind the Success of the Tasmanian Greens In 1972 the world’s first Green Party, the United Tasmania Group, won 3.9% of the vote in a state election. Thirty years later, in a 2002 state election, the Tasmanian Greens won 18.1% of the vote, the highest ever by a Green Party. This thesis investigates three influences on the Tasmanian Greens and the cause of their recent electoral successes. These factors include the strong ethical and philosophical base established by the United Tasmania Group, the intra-party politics and leaders of the Tasmanian Greens, and the nature of political relationships between the Greens and other parties in the Tasmanian state and electoral systems. It also examines a shift in Tasmanian culture and an increase in post-material values resulting in a new consideration for environmental politics. The Tasmanian experience is critical to the global Green movement, not only because it is the world’s oldest Green Party, but because newly forming parties can look to the Tasmanian Greens as a model for success.
Melissa Kay '04 Michael Sargent, Psychology Predicting Student Alcohol Use with the Implicit Association Test (IAT) Study 1 used four separate Implicit Association Tests (IATs) to examine students’ implicit alcohol attitudes. Based on Jajodia and Earleywine’s (2003) results that positive alcohol expectancies better predicted students’ alcohol use than negative expectancies, it was hypothesized that the same would be true for Bates students. Furthermore, it was predicted that associations on the IATs would better predict unplanned alcohol use than planned use. Also, the IATs should better predict alcohol use in more impulsive individuals since their alcohol use is probably more often unplanned. The only significant results were that more extraverted people drink more and people who planned to drink more actually drank more (ps <.05). Study 2, which employs a different measure of alcohol use and impulsivity, is currently underway.
Benjamin Kercsmar '04 Cheryl McCormick, Psychology Male Signaling Honesty, Female Mate Choice, and Maternal Contribution to Offspring in Swordtail Fish (Xiphophorus helleri) Reproduction is at the heart of survival, and at the heart of reproduction is mate choice. Choosing the right mate can greatly enhance a female’s offspring. Males of many species signal their fitness through body size, ornamentation, or courtship behavior. Ideally the signal would reflect the true fitness of the male, but this is not always the case. The female relies on these signals to choose a mate, to determine how much he will contribute to her offspring. The more fit her mate, the more resources she can offer to her offspring. By modifying the male signal-body size via the extended tail “sword” and measuring the quality of their mate’s offspring, I attempted to draw a correlation between male signals and female contribution to offspring in swordtail fish, Xiphophorus helleri.
Samara Khalique '04 Kathryn Low, Psychology Psychosocial Attributes as a Predictor of Metabolic Syndrome Risk Factors in Females Several studies have shown that hostility, defensive hostility, depression, and stress may be risk factors for cardiovascular and metabolic functioning. The metabolic syndrome is a clustering of risk factors for both CHD and diabetes, which involve elevated levels of fasting insulin and glucose, visceral obesity, HDL-C, triglycerides, and blood pressure. Many of these studies have focused primarily on older at-risk males and females. Thus, this study examined psychosocial attributes (i.e., hostility, stress) and whether they are related to the metabolic syndrome in young adulthood. The correlation between psychosocial attributes and the metabolic syndrome risk factors (i.e., high blood pressure, glucose) in 40 young adult females at
Brian Kile '04 Matthew Côté, Chemistry Parallel Fabrication of Metal Oxide Nanostructures Size-tuneable nanostructures are the basis for the field of nanotechnology. Nanostructures are currently being used in a wide variety of applications to enhance current miniaturization technologies. Metal oxide nanostructures are more powerful in that they combine the properties of metal oxides with those of nanostructures. Parallel fabrication methods such as atomic layer deposition can be used to fabricate large numbers of nanostructures simultaneously. Atomic layer deposition of titanium dioxide from titanium tetrachloride and water has been combined with masking technology to create highly ordered arrays of titanium dioxide nanostructures.
Gianna King '04 Michael Sargent, Psychology Alcohol Expectancies and the Role of Television: Does Perceived Realism Affect Attitudes about Alcohol? Research indicates that viewing alcohol in the media may play a significant role in the formation of attitudes about alcohol and drinking behavior. Prior studies have also suggested that the perceived realism of the media is a crucial factor in how people internalize media messages. This experiment investigates how the perceived realism of television content affects students’ alcohol expectancies (which are a reliable predictor of drinking behavior). Participants in the experiment view a 15-minute video, which is a collection of clips from a British reality show containing alcohol. To manipulate perceived realism, half of the participants are told they are viewing a reality show, while the other half are told they are viewing a film in which actors parody reality television. Participants then complete several measures, which assess both implicit and explicit attitudes about alcohol.
Kathleen Kolstad '04 Jennifer Koviach, Chemistry Effects of Tetrandrine (TET), Isolated from the Chinese Herb, Stephania tetrandra, on NMDA Receptor Subunits Expressed in Xenopus laenis Oocytes Tetrandrines (TET) is a primary active compound found in the traditional Chinese herbal medicine, “Feng Fang Ji.” Tetrandrine is a well-characterized calcium channel antagonist. The compound’s inhibitory effects have been primarily studied in smooth muscle cells. The purpose of this study is to isolate TET from the root of Stephania tetrandra and explore the compound’s ability to inhibit NMDA mediated neural excitation. This study will contribute to understanding the mechanism of TET’s action as an ion channel antagonist as well as explore TET’s potential as a therapy against stroke-induced cellular excitotoxicity.
Katherine Kopeikina '04 and Daniel Robarts '04 Cheryl McCormick, Psychology Effects of Adolescent Stress on Nicotine-Amphetamine Cross-Sensitization During specific, critical periods of brain development, environmental factors can cause long-lasting changes. Stress during prenatal and neonatal stages of life have been shown to create long-term physical and behavioral changes in rats, but until recently the adolescent stage has not been considered. Some of the neural circuitry that is changed by stress also mediates the effects of psychostimulant drugs, such as nicotine, amphetamine, and cocaine. To further examine the long-term effects of adolescent stress, we stressed adolescent rats and later, in adulthood, tested their behavioral response to nicotine and amphetamine. Findings suggest a general trend for stressed females to show greater locomotor activity to nicotine than the control females, whereas stressed and control males did not differ. There was an interaction between sex of the animals and stress in the response to amphetamine, with a significant sex difference between stressed and control rats: stressed males tended to be less active than control males when given amphetamine, and stressed females tended to be more active than control females when given amphetamine. These findings suggest neuronal changes occurring in the reward pathway of the brain during stress, altering later reactions to drugs such as amphetamine.

Justin Levesque '04 Antonio Planchart, Biological Chemistry Construction of a Novel Synj2 Plasmid Synaptojanin 2 (Synj2) encodes a type II 5-phosphatase that regulates development in many organisms, including mice and humans. Synj2 contains an N-terminal Sac-1-like domain, a central inositol polyphosphate 5’-phosphatase (IPP5Pase) domain, and a praline-rich carboxyl terminus. Both the Sac-1 and the IPP5Pase domains are catalytically active; mice with mutations in these sites show neurological and reproductive defects (Planchart 2004). An ORF in the 3’ region of Synj2 can be alternatively spliced, producing a truncated form of Synj2 (termed Synj2Assac1) that excludes part of the catalytic Sac-1-like domain (Khvotchev and Sudhof 1998). The exact enzymatic properties and subcellular location of Synj2Asac1 are unknown. The purpose of this project is to construct a plasmid with the pcDNA3.1 cloning vector and PCR amplified Synj2Assac1 using Pfu Turbo polymerase. The inclusion of a FLAG-tag will help in recovery of the expressed protein. Characterization of the enzymatic properties of Synj2Asac1 will then be possible.
Jeffrey Levinson '04 Mark Semon, Physics New Variables for Quantum Interference This thesis investigates two new dynamical variables for describing quantum interference: the modular momentum and the modular position. These variables were introduced in 1969 but have received little attention. The first part of the thesis reviews the theory of the double slit experiment, while the second part reviews the scalar Aharonov-Bohm effect and its experimental verification. Then the modular momentum is introduced and shown to be the only variable known to change in the effect. Other properties of the modular momentum are derived and its physical significance is established. The modular position is then introduced and shown to commute with the modular momentum, proving that certain functions of position can commute with certain functions of momentum. The thesis ends with a discussion of how modular variables might be used as the basis of a non-local theory of interactions that describes quantum interference experiments. In this way, the thesis develops a new dynamical formulation of the scalar Aharonov-Bohm effect using modular variables.
Jesse Lewin'04 Heather Lindkvist, Anthropology Interactions between Somali Secondary Migrants and Physicians in Lewiston, Maine: An Ethnographic Field Study in Refugee Health Care and Cultural Competency This thesis aims to determine what factors influence the health care of Somali secondary migrants in Lewiston, how Somalis understand American health care, and how American physicians understand and interact with Somalis. Medical anthropologists have studied the physician-patient relationship in Western biomedicine extensively over the last two decades. Research has focused on the various hegemonic forces involved in shaping this encounter, and implicitly the respective roles of the participants. These studies have demonstrated that certain cultural, linguistic, intercultural, and interactional elements influence the physician-patient relationship and have the potential to create difficulties in achieving accurate diagnosis and treatment. Such barriers to diagnosis and treatment may be exacerbated when the patient is an immigrant or refugee and the provider is not knowledgeable about the patient’s cultural background and health beliefs. Studying this interaction continues to be important especially with current demographic transformations in the United States, and locally with the influx of nearly 1,200 Somali secondary migrants to Lewiston, Maine. Using documentary research and semi-structured interviews with Somali secondary migrants and local physicians, this thesis examines the interaction between Somali patients and Western-trained physicians in order to examine the shortcomings of the present system and to promote increased communication and understanding.

Brent Mann '04 Jennifer Koviach, Chemistry Synthesis of 2-Deoxyglycosides through Acid-Mediated Conjugate Addition 2-deoxyglycosides are ubiquitous among natural products and are key members of many antibiotics, and anti-cancer agents. The synthesis of such molecules can be a tricky endeavor due to the lack of a control element at the C-2 position. We have developed a procedure using acid mediated conjugate addition to form disaccharides in significant yield. We have also developed two multi-step methods for the preparations of D-amicetose, and L-axenose. These two monosaccharides will be combined to form a 2-deoxy sugar which has never before been synthesized.
Kathryn Mannle '04 Peter Rogers, Environmental Studies Ecotourism Opportunities and Challenges at Masoala National Park, Madagascar Numerous challenges and opportunities exist for ecotourism at Masoala National Park, a coastal forested area in northeastern Madagascar. Many factors make Masoala National Park a prime ecotourist destination, including the possibility of viewing its endemic species. However, limitations on ecotourism development include poor infrastructure and difficult access, a challenging climate including a hurricane season, and past national political instability. For several months in 2001 and 2003, interviews, participant observation, and archival research were used to investigate the park’s guide association, visitor, and resident attitudes toward Masoala National Park, and ecotourism as a method of park and rural development. Actual or potential benefits received from the park, including ecotourism revenues, were found to influence the perceptions of Masoala National Park held by residents living in the park periphery. An overview of the current state and future potential of ecotourism at Masoala Nation Park is presented, along with possible steps to be taken to improve ecotourism initiatives.
Rachel Martin '04 Kathryn Low, Psychology Endorsement of the Protestant Ethic and Body Dissatisfaction Body image, body dissatisfaction, and disordered eating have been increasing concerns in contemporary culture. Research has explored sociocultural influences on body esteem, including, family, peers, and an American ideology, the Protestant ethic. A recent study done by Quinn and Crocker (1999) looked at the Protestant ethic as a possible contributing variable to women’s dissatisfaction with weight. The Protestant ethic is an ideology that includes the belief that individual hard work leads to success and that lack of success is caused by the moral failings of self-indulgence and lack of self-discipline (Quinn & Crocker, 1999). The current study looks at a fairly homogenous liberal arts college sample to test the influence of the Protestant ethic on body image in men and women. Both men and women seem to endorse the Protestant ethic equally, but men seem to be more aware of the thin ideal. The Protestant ethic is more closely associated with internalization of media images in men than in women. Similar to previous research, women with higher body mass index (BMI) and high scores on the Protestant ethic were most dissatisfied with their bodies. For men, lower BMIs were associated with greater dissatisfaction.
Elizabeth McConnell '04 Amy Bradfield, Psychology How Race Affects Jury Comprehension of Judge’s Instructions In previous research, Sargent and Bradfield (in press) asked: Does a defendant’s race affect how jurors will evaluate the facts of a trial? They found highly motivated jurors relied on alibi strength in deciding the case regardless of the race of the defendant. However, jurors paid more attention to the black defendant’s case regardless of their level of motivation. This thesis applies these findings to juror comprehension of judge’s instructions. Judge’s instructions are often complicated and jurors rely on superficial, peripheral cues when judging cases. In this thesis, two variables were manipulated: race of defendant (black v. white) and motivation of the participant (high v. low). It is hypothesized that those participants in the high motivation condition will attend to and therefore comprehend the judge’s instructions better than those participants in the low motivation condition, except when the defendant is black. When the defendant is black, regardless of the level of motivation, participants will pay closer attention to the judge’s instructions presumably because of the modern racism theory.

Kelton McMahon '05 William Ambrose, Biology Contributions of Local Food Items to the Diet of Fundulus heteroclitus Stable δ 13C and δ 15N isotope analysis and gut content analysis of Fundulus heteroclitus trapped at three locations along a major creek and in a pool in the middle of a salt marsh in southern Maine were used to determine the contribution of local food items to F. heteroclitus diet. In general, Fundulus consumed significantly more plant than animal matter. Abundance of Ulva lactuca was significantly higher in stomachs from the most landward site as compared to the middle pool site and the site nearest the ocean, and leaf particles were significantly more abundant in stomachs from the most landward site as compared to the other three sites. Stomach content data were compared to stable isotope data. Based on stomach contents, Fundulus within different regions of the marsh appear to feed on food available at those locations rather than traveling to distant regions of the marsh to feed.
Julia McQuade '04 Georgia Nigro, Psychology The Facilitative Effects of Drawing and Puppets on Children’s Reports of Positive and Negative Events This thesis examines how young children narrate experienced emotional events. In particular, it looks at children’s narratives using three different interview techniques. Previous research suggests that when interview techniques reduce the social demands placed on children, they report more information about emotional experiences. This study builds upon past research that has found that drawing during recall enhances the reports of young children. In addition, it investigates whether puppets could similarly reduce social demands during an interview. In this study, five- and six-year-old children from a local elementary school experience an event in their classrooms that includes two interruptions, one positive and one negative that are similar in length, causality, and temporal sequence. Following the event, children are assigned to a drawing, puppets, or verbal recall condition and individually interviewed about what they remember. The results of this thesis will add to our understanding of the effectiveness of drawing as a narration tool, resolve the question of whether nonspecific props, such as puppets, enhance children’s reports, and clarify questions about children’s narrations of positive and negative experienced events.
Saul Miller '04 Michael Sargent, Psychology The Effect of Processing Goals on the Memory of Ambiguous Behaviors Previous research – on which the present studies are based – has shown that attempting to form an impression while learning about a person’s behaviors often leads to better memory for those behaviors than attempting to memorize them. However, Experiment 1 indicated that this may not be true when the person about whom we are forming impressions performs behaviors that are ambiguous. The purpose of Experiments 2 and 3 was to confirm that it was the ambiguity of the statements that explained why the typical effect of impression formation instructions was not replicated in Experiment 1. This goal is accomplished by experimentally manipulating the ambiguity of the statements (within-subjects in Experiment 2 and between-subjects in Experiment 3). The purpose of Experiment 4 was to determine if the typical effect of impression formation instructions can be replicated with even ambiguous statements, provided that perceivers are given a prior expectancy about the target individuals, and that this expectancy serves to disambiguate the statements.

Jurgen Nebelung '04 Michael Daley, Economics and Environmental Studies Motivations for Green Design in Homes As the demand for fossil fuels grows, individuals are looking for ways to reduce their portion of the demand. There are many ways we can accomplish this. One way is through building more resource-efficient, green homes. This research investigates the motivations for green design. It also highlights the design techniques and technologies that are built into many green homes to help make them more resource efficient not only in their operation but also construction. Finally, I pose some reasons why green design is not more prevalent in our society.
Joseph Northrup '05 and Lani Stinson '05 Joseph Pelliccia, Biology Abundance and Distribution of the Macroinfauna at Long Sands Beach; York, Maine The sand of intertidal beaches supports an assemblage of small invertebrates. Patterns of distribution of these organisms are poorly known. If the natural variation in the system can be understood then these organisms may be useful as indicators of human perturbations on sand beaches. For this study animals were collected from several tidal elevations. Collections were made along transects perpendicular to the shoreline during spring and neap tides to compare species distribution and abundance during different tidal regimes. Longshore transects were used to examine differences in species distribution and abundance along the shore at the same tidal elevation. Additional collections were taken to assess temporal changes in abundance resulting from the mobility of these organisms.
Matthew Ondra '04 Lee Abrahamsen, Biology Metallothionein in Cadmium Detoxification and Bioremediation This presentation focuses on the detoxification and bioremediation of the heavy metal cadmium by use of the protein metallothionein. Metallothionein is a heavy metal binding protein naturally found in eukaryotes as well as many prokaryotes. In the body metallothionein functions in metal detoxification as well as regulation of essential metals such as zinc and copper. While heavy metals cannot be broken down, metallothionein is capable of binding these toxic metals to make them less reactive. Research has been done with this protein in efforts to increase its expression and use it as a bioremedial agent in minimizing the toxic effects of cadmium contamination from industrial refineries and batteries.

John Kelsey, Psychology Effects of Varying Durations of Abstinence on the Expression of Locomotor Sensitization in Cocaine-Addicted Rats Previous studies in both self-administration and locomotor sensitization models have shown that expression of cocaine and amphetamine addiction increases across abstinence periods as great as three months or more. These studies indicate that the expression of addictive behaviors, rather than decreasing during abstinence, may actually grow. We replicated this “incubation” phenomenon using locomotor sensitization in response to cocaine and examined the possible role of memory. Rats previously sensitized to cocaine showed the predicted linear increase in the expression of locomotion in response to a challenge injection of cocaine following 3, 8, and 15 days of abstinence. Injections of saline during the first 5 days of abstinence eliminated this incubation effect, indicating that this incubation effect can be extinguished. This incubation effect and its elimination have implications for the maintenance and treatment of drug addiction.

Generational boundaries, technological advancements, and the development of strong community bonds and distinctive ethics have brought climbing from the mythical “Mountain Man” to the everyday lives of New Englanders.
Jessica Perrie '05 Lee Abrahamsen, Biology Are Heifer Project International Cows Healthier? The long term goal of Heifer Project International (HPI) is to improve the socioeconomic level of Tanzanian farmers and to ultimately improve human health. The purpose of this study was to assess the overall health of cows provided to families in the village of Ngejisosia, Tanzania, by HPI, compared to non-HPI cows in that village. Farming efficiency, milk production, disease presence, and parasite load were assessed. Farmers were given questionnaires to evaluate farming efficiency and fecal samples were taken from their cows to assess parasite load. I predicted that farming efficiency, milk production, disease presence, and parasite load would be better on HPI farms, compared to non-HPI farms. Results supported this hypothesis. Overall, HPI farmers thought that their farming techniques were more efficient than non-HPI farmers. I concluded that Heifer Project International Tanzania (HPIT) provided adequate education in animal health and husbandry to its clients in the village of Ngejisosia for maintaining healthy livestock.
Tory Peterson '04 Bonnie Shulman, Mathematics A New Twist: Different Models for the Tacoma Narrows Bridge Collapse On November 7, 1940, the Tacoma Narrows Bridge began undergoing vertical oscillations that changed to a twisting motion and led to the failure of the bridge. I have looked at several models to explain the cause of the collapse. Many use the Tacoma Narrows Bridge disaster as the canonical example of resonance. While resonance may be qualitatively correct, the source of the periodic external forcing frequency that would produce this phenomenon has not been convincingly established. Today’s numerical solvers enable us to find numerical solutions and experiment with different parameters and initial conditions that may have influenced the behavior of the bridge. I experiment with both uncoupled (vertical and torsional motion are independent) and coupled nonlinear models, and investigate whether vertical motions can lead to torsional motions, to explain the unusual twisting that eventually led to the bridge’s collapse.
Toby Pinn '04 Joseph Pelliccia, Biology Lethal White Foal Syndrome: An Equine Genetic Puzzle Throughout history horses have been selectively breed to isolate specific traits and achieve valued coat color patterns. Among these patterns is the overo coat type. The term overo refers to jagged white markings on the horse’s abdomen that extend dorsally to, but not over, the midline. One challenge that breeders have faced in achieving overo offspring is the production of progeny with Lethal White Foal Syndrome (LWFS). Foals with LWFS are almost completely white due to an absence of melanocytes; they die within days from intestinal obstruction. Horses displaying the overo pattern do not exhibit pure breeding, and for this reason an overo x overo cross can produce LWFS offspring. Although a recessive model of autosomol inheritance was originally suggested for LWFS, research most strongly supports a dominant spotting gene as responsible for LWFS in the homozygous form. Genetic analysis has identified the cause of LWFS in the homozygous form. Genetic analysis has identified the cause of LWFS to be a dinucleotide missense mutation in the endothelin B receptor gene (EDNRF), a component of the endothelin-signaling pathway. One anomaly associated with LWFS is the lower incidence of reported LWFS foals than predicted by the genetic model. Santschi et al. proposes that modifier genes are the source of this variance.
Stephanie Praino '04 Curtis Bohlen, Environmental Studies Aldo Leopold and Ideas of Sustainability My presentation explores the developing conservation ideologies of Aldo Leopold and his land ethic, through his life work and career as an ecologist and educator, in relation to present-day interpretations of sustainable development. I believe that many of Aldo Leopold’s principles behind his conservation philosophy and practices represent ideas similar to those key notions of education and long-term planning found in the broad spectrum of sustainable development philosophy. However, the concept of sustainable development lacks this foundation of ethical respect and treatment for the environment beyond human welfare, which remains at the core of Aldo Leopold’s land ethic.
Bradley Proctor '04 Joseph Hall, History What Say Banjer? The Shared Black and White Banjo Traditions of the American South This research concerns the history of the banjo in the United States South. Originating in Africa, the banjo was codified into its currently recognizable form by African slaves in the Americas during the seventeenth century. Sometime in the eighteenth and nineteenth centuries, whites in the Southern United States began to play the instrument as well, learning primarily through apprenticeship to slaves and free blacks. In the twentieth century, the blues developed out of the African American banjo tradition, and bluegrass emerged out of the European-American banjo tradition. Though both are distinct musical forms, they share characteristics often ignored when studied separately. Despite socially ingrained racism and substantial political barriers to white and black interaction, both the black and white banjo traditions were defined by a sharing of culture between the two groups.

Jason Rafferty '05 Heather Lindkvist, Anthropology Siofua Malōlōina: Bringing “Health” to Samoa’s Rural Villages Through the many rural facilities and services offered by the Samoan Department of Health, on-governmental organizations, and community organizations, access to health care has become possible for everyone. However, maintaining a high level of care in the rural areas of the country is the biggest challenge, especially as rural hospitals are faced with a lack of clinicians, essential resources, and very poor facilities. Although scaled back, health services are still being provided to all areas with most of the responsibility falling on a limited number of nurses. In recent years, the Department of Health has implemented an “integrated” or community-based approach to preventative and educational services. Surveys show that this approach is effectively making people aware of health risks and their responsibilities towards prevention. Maintaining the high quality of life in Samoa requires creative planning, such as developing partnerships between governmental and non-governmental organizations, and looking at ways to get community members more involved in the pre-hospital setting.
Lauren Randall '04 and Ayana Sawai '04 T. Glen Lawson, Chemistry Effect of pH on Antibiotic Resistance of E. coli Genome Mutated with Transposon CamR and KanR Our project investigates the effect of pH on antibiotic resistance of the E. coli genome mutated with transposons CamR and KanR, which code for resistance to the antibiotics chloramphenicol and kanamycin, respectively. We formed E. coli mutants by infection with a transposon and verified the results via PCR and gel-electrophoresis. Non-transposed E. coli and transposed E. coli were tested to see if they could grow in the presence of an antibiotic at three pHs. We do not expect the non-transposed E. coli to grow. If the transposed E. coli grows, this implies that it is a good pathogen in the presence of the antibiotic. If the transposed E. coli does not grow that implies that the E. coli is no longer an effective pathogen in the presence of the antibiotic. This project is a model system for E. coli as a pathogen and may possibly lead to information regarding the risk of evolving antibiotic-resistant pathogens via transposons.
Paula Schlax, Chemistry RNA Interference and Its Application to Developing Therapeutic Techniques Short interfering (siRNA) molecules are 21-23 nucleotide double stranded RNA duplexes that have symmetrical overhands of 2 to 3 nucleotides in length complete with 5’-phosphate and 3’ hydroxyl groups. Findings have shown that synthetically made duplexes can be specifically designed and applied for efficient mRNA degradation of target genes. These results suggest that siRNA duplexes can potentially be used as a tool for sequence- specific regulation of gene expression in functional genomics as well as in biochemical studies. In addition, this mode of RNA interference (RNAi) provides possible new alternatives to antisense or ribozyme techniques, as well as demonstrating great potential for applications to that of developing therapeutics.
Jennifer Reynolds '04 Antonio Planchart, Biological Chemistry Genetic Analysis of Transmission Ratio Distortion in t haplotype Mice The t haplotype is a mutant form of mouse chromosome 17 that results in male sterility if homozygous, and transmission ratio distortion (TRD) when heterozygous. TRD is characterized by a high transmission (up to 99%) of the t haplotype from males to their offspring. Several factors, including the responder, distorters and sterility factors, located within inversions comprising the t haplotype are responsible for the male-specific effects observed. Synaptojanin2, located in the proximal part of chromosome 17, is mutated in t haplotypes. Inserting a wild-type copy of Synaptojanin2 through transgenic technology restores fertility in male mice. To determine the effects of the transgene on TRD, the transmission of chromosome 17 to offspring from males with and without the transgene was determined by PCR analysis. The transgene had no effect on the transmission of chromosome 17 indicating that Synaptojanin2, while rescuing sterility, is not involved in TRD thus separating these two phenomena.

I am evaluating these data in the hope of learning more about the effects of the program and possibly discovering possibilities for improvement of the program.
Colin Schless '04 Jane Costlow, Russian and Environmental Studies A Study of “Nature” Healing The area of human culture in which I study the role of “nature” is an alternative healing program called Two Roads of Maine. Two Roads is an organization that takes physically ill or traumatized persons out into the wilderness, where the organization uses a variety of methods to “heal” the participants. The process borrows from Shamanic and Buddhist traditions, yet conducts its practices in its own unique ways. I study the role that “nature,” or the “wild” aids in the healing process of individuals. This includes references from thinkers such as Trigant Burrough and Edward O. Wilson.
William Schmitt '05 and Juyoung Shim'05 T. Glen Lawson, Chemistry The Mutagenic Effects of Benzopyrene and UV Light on the pUC18 Plasmid ampr Vector Our group intends to investigate the effects of selected mutagens on the E. coli pUC18 plasmids containing the ampicillin resistance gene (1076bps) coding for the β-lactamase enzyme. The objective of this research is to uncover the distinct mutagenic effects of both benzopyrene and UV light on the open reading frame of the ampr vector. Mutagenesis may be performed by exposing competent bacterial colonies, previously transformed with the ampr plasmid in the presence of ampicillin, to either of the two mutagens and allowing sufficient time for the mutated DNA strains to replicate. Approximately one half of the colonies containing the MUTATED plasmid will then be tested with a Kirby-Bauer Disk Diffusion Test. Those sub-colonies destroyed by ampicillin indicate the presence of significant mutations in the plasmid DNA coding for β-lactamase. Therefore, the mutated plasmids of the remaining half of the colonies will be extracted for sequencing. The sequence of the mutated plasmid DNA will be compared to the already obtained sequence of the non-mutated plasmid DNA strain (from NCBI). These comparisons will allow conclusions to be drawn on the specific nucleotide mutations in the DNA experienced from exposure to benzopyrene or UV light.

An Investigation through the Lens of Self-Construal Theory Study 1 investigated the relationship between self-construal and self-reported experiences of physical and social aggression and victimization in adolescents. Eighth-grade participants completed the Relational-Interdependent Self-Construal scale (Cross, Bacon, & Morris, 2000) measuring the degree of interdependence of their self-construal (i.e., how much they thought of themselves in terms of their relationships with close others), and the Revised Peer Experiences Questionnaire (Prinstein et al., 2001) on which eighth graders reported how often they experienced physical aggression, physical victimization, social aggression, and social victimization. Results indicated that girls scored higher on the RISC scale, suggesting that they have more interdependent self-construals than boys. The only gender difference on the RPEZ was in social victimization, as girls reported being the victim of social aggression more than boys. No correlation existed between scores on the RISC and RPEZ, signifying that physical and social aggression were unrelated to self-construal. In study 2, eighth graders were primed with either an independent or interdependent self-construal, and completed the RPEZ again to investigate whether priming affects reported aggression.
Hillary Schwab '04 Peter Rogers, Environmental Studies British Columbia’s Community Forest Pilot Agreement This thesis examines British Columbia’s Community Forest Pilot Agreement (CFPA) using the theoretical tools of common property theory and political ecology. Forestry has been an economic mainstay for British Columbia since its establishment in the nineteenth century. As an export-led economy, the forest industry has been characterized by long-term industrial government-issued forest leases and corporate concentration of forest land. The history of British Columbia forestry leaves a legacy of largescale environmental and social impacts on all citizens of that province, including labor, communities, First Nations, NGOs, industry, and government. In a dwindling market with increased international competition,
Rebecca Seifers '04 Frank Chessa, Philosophy and Environmental Studies The Ethics of Ecotourism Ecotourism is an industry that claims to uphold certain moral standards. It formed as a reaction to the immoral actions of the tourism industry that have caused large-scale environmental destruction and social problems. But, does the ecotourism industry today demonstrate ethical concern for the environment and local cultures? Or, has the use of the label “ecotourism” become merely a marketing strategy for resorts to attract customers looking for a “green” alternative? My research analyzes many ecotourism companies finding a range of ethical concern in the industry. Using specific resorts as examples I illustrate the range of ethical concern found in the ecotourism industry today.
Luke Selby '05 and Sarah Tolford '04 T. Glen Lawson, Chemistry Analysis of Mutagenesis to the CAP Binding Site of lac Promoter All prokaryotic organisms use glucose, a six carbon sugar, as their primary energy source. In no glucose environments Eschecheria coli (E. coli) activates a series of linked genes known as the lac operon in order to metabolize lactose, another six carbon sugar energy source. The lac operon is roughly 6000 base pairs in length, and contains a repressor gene; an operator sequence, the three genes required to metabolize lactose; and a terminator sequence. The lac promoter is a DNA sequence that allows the binding of a CAP-cAMP complex, which is indicative of low cellular energy levels. This binding increases the production of genes required to metabolize lactose. Using Enhanced Green Fluorescent Protein (EGFP) as a reporter, we will mutate a conserved DNA sequence in the lac promoter (-44 CCCC -41). We expect to see a decrease in EGFP production with any deviation from this conserved sequence.
Melanie Shaw '04 Pamela Baker, Biology Chemical Applications in Orthodontics My thesis explores the relationship between chemistry and orthodontics. Focusing on the alveolar bone, it shows how teeth move as a result of orthodontic appliances. The force caused by these appliances manipulates the bones, thus causing the teeth to move.
Juyoung Shim '05 Pamela Baker, Biology Effects of Herbal Medicine on Periodontal Disease One of the most remarkable developments in recent years in health community in the United States is the emergence of medical therapies and procedures commonly referred to as alternative medicine, such as acupuncture and phytotherapy (treatment with natural herbs). Chinese herbal medicine in particular is gaining popularity in Western culture as an alternative approach to the development of pharmaceutical applications. This study investigated two herbal medicines, Huang Qi (astragalus membranaceus) and Hunag Lian (Rizoma Copidis), for their effectiveness in preventing periodontopathic microorganisms. Periodontal diseases are chronic inflammatory diseases that can result in degeneration of the gum structure that support the teeth and the loss of the alveolar bone of the jaw. Those herbs are common component of Chinese herbal formula and have been presented as an immune stimulant useful for defensive shields for pathogens. Therefore we can examine the action of the herbs by measuring of the alveolar bone loss between control group and treatment group. We employed the mouse model and they were infected with a bacterium called Porphyromas gingivalis which is an oral anaerobic bacterium associated with periodontal disease in human. After two weeks from infection, Huang Qi and Hunag Lian were fed to mice in treatment group for six weeks in their drinking water. After the termination of the mice, the blood was collected for the ELISA test and the alveolar bones of each mouse were measured at 14 different sites (7 sites at each site) under the microscope using video image technique. The analysis from the data demonstrates if the herbs had any protective effect on bacterial infection and if they did, how well they prevented alveolar bone loss.
Sociology Thesis Panel Emily Kane, Sociology Social Inequality and Social Change In this panel, we explore a variety of contemporary social problems in the context of their links to social inequality and social change. Our presentations address educational policy, international trade agreements, the juvenile justice system, and the social dimensions of anorexia nervosa. We analyze these social problems with a focus on inequalities of race, class, nation, and/or gender. We also emphasize implications for social change, ranging from public policy responses to social movement and community initiatives to individual narratives of recovery from anorexia. - Emily Barko '04: Narratives of Anorexia: A Qualitative Analysis - Elizabeth Jackson '04: The Role of NGOs in the Emergence of Transnational Social Movements: A Look at the Movement Opposing the Free Trade Area of the Americas - Tanya Schwartz '04: The ABC’s of Success: The Effects of Parents, Schools and Communities on Young Children’s Academic Achievement - Heather Tompkins '04: Pathways Home: Aftercare for Girls in the Juvenile Justice System

Johanna Sterzel '04 Georgia Nigro, Psychology A Case Study: The Effects of Exercise on the Self-Stimulatory Behaviors of a Nonverbal Child with Autism A four-year-old nonverbal boy with low-functioning autism exhibited self-stimulatory behaviors. Stereotypy, hyperactivity, and noncompliant behavior hindered his ability to benefit from a structured learning program at the Margaret Murphy Center for Children with developmental disabilities in Auburn, Maine. An intervention of mildly strenuous outdoor jogging was introduced into his learning program to test whether the exercise had any differential effects on academic performance.
Kathyrn Stevens '04 Georgia Nigro, Psychology Interpreting Federal Educational Reform in a Local Context: Three Teachers’ Lived Experiences with the No Child Left Behind Act Over the past few decades, the federal government has made several attempts to close the socioeconomic and race-related achievement gaps among the nation’s students through standards-based school reform. Despite these efforts, the gaps remain. Although the problem of educational inequality has been studied from many different angles, inadequate attention has been paid to what teachers think about this dilemma, particularly when it comes to creating and sustaining successful reform. Psychologists possess a unique combination of evaluative, clinical, and organizational skills, and thus can offer useful perspectives on these issues. This thesis presents an analysis of three teachers’ experiences with the most recent federal educational reform, the No Child Left Behind Act (NCLB). Through three case studies, I aim to understand the interpretive processes that staff employ in response to large-scale educational change and highlight NCLB’s strengths and weaknesses through the eyes of the teachers. I conclude with a discussion of the implications for future educational policy.
John Sullivan '04 Antonio Planchart, Biological Chemistry Spatial and Temporal Expression of Tcte1L and Tctex1, Dynein Light Chain Paralogs This project is designed to examine the tissue-specific and developmental expression patterns of the genes Tcte1L and Tctex1 that encode similar dynein light chains. Dynein light chains are components of larger protein complexes known as dyneins that function as molecular motors and are capable of performing a variety of cellular functions. For example, dyneins are involved in the processes of chromosome segregation, the movement of organelles within the cell, transport along nerve axons, flagellar and ciliary motility and play a role in establishing the left-right organ asymmetry during mammalian development. To better characterize the expression patterns of Tcte1l and Tctex1 we plan to use mice, arrange timed matings and remove the developing embryos at various time points in their 21-day developmental program. The embryos will be used mainly for in situ hybridization of antisense mRNA to identify expression patterns of Tcte 1l. The antisense mRNA will carry a fluorescent tag and will bind the complementary sense mRNA produced by our gene of interest if it is active during that developmental stage. My presentation will expand on this general outline and provide slides of embryos that have been successfully hybridized and demonstrate expression.
Lucia Tiererova '06 Robert Allison, Religion The Watermark Initiative: Database of Papers and Watermarks The Watermark Initiative (WMI), a joint project of Bates professor Robert Allison and Information and Library Services staff member James Hart, was founded because of the need to design and develop a distributed database of historical papers and watermarks. Modern researchers need flexible tools for data storage that are accessible throughout the world. Storing descriptions of watermarks and papers in electronic form provides a suitable means of preserving and disseminating data, and greatly enhanced search capabilities while avoiding the need for bulky printed catalogs. The WMI is now collaborating with several related projects and organizations around the world (i.e., Digital Scriptorium; the Ancient Biblical Manuscripts Center in
Sarah Tolford '04 Lee Abrahamsen, Biology A Protein Purified from Hyacinth Beans Has Potential for Treating Cancer FRIL, Flt3 receptor-interacting lectin, is a plant lectin purified from hyacinth beans which has been shown to activate proliferation of certain cells and preserve quiescent primitive stem cells for one month in culture. This lectin, therefore, has numerous possible clinical applications for treating cancers and enhancing organ and stem cell transplantation. In order to gain FDA approval as a clinical drug, the active components of FRIL must be identified and purified. Samples from 24 different Dolichos lablab cultivars grown in various countries worldwide were purified using an affinity column and each exhibited 5 bands upon SDS-PAGE analysis. These 5-bands were uniform in all cultivars and ranged from 10-22 kDa. The FRIL produced by each cultivar contained varying concentrations of FRIL when normalized to bean weight. This study identified structural homology in the FRIL produced by hyacinth beans, a crucial finding for the next stage of drug development.
Sarah Tressel '04 Robert Farnsworth, English Comfort and Discomfort: Revisiting Ghana through Poetry My thesis voices my experience abroad in Ghana through poetry. Living in Ghana, I developed an understanding and appreciation for the culture and its people. My connection to this amazing country has shaped my identity and helped me question the differences between Ghanaian and American culture. In my presentation, consisting of reading selected poems from my thesis, I hope to provoke discussion. I have encountered both comfort and discomfort in reliving memory through my poems. Using my own sense of place in Ghana, I want to emphasize how two cultures at once clash and harmonize.
Christopher Urban '04 Carl Straub, Religion and Environmental Studies Managing People and Wilderness in the Northeast Kingdom of Vermont: A Study of Constructive Conservation Policy Throughout history, people have argued and fought over places in an effort to control and improve their own destinies. This simply would not occur if people did not care about the continuation of their sense of place. Over generational time, Vermont’s Northeast Kingdom culture has evolved in connection with the land to form a unique niche-place. In 1999, a large timberland deal divided 133,000 acres of the Northeast Kingdom into three parcels. The most controversial parcel is the 22,000 acre West Mountain Wildlife Management Area, with an inner 12,500-acre ecological core reserve. This study examines the debate over who should manage West Mountain and consequently what policies should guide the management. The debate reveals cultural differences rooted in two competing senses of place. The two senses of place can be generalized as the traditionalist and the environmentalist. The thesis is that such cultural differences can be reconciled by developing a common third management policy. Such a policy takes seriously the shared values of the present antagonists and yet moves beyond them to encourage a new way of understanding the intricate interrelationships between people and their ecological environments.
Graham Veysey '04 Áslaug Ásgeirdóttir, Political Science and Environmental Studies Environmental Discourse and the Three Gorges The history of the Three Gorges Dam project is told one way by environmentalists, another way by the Chinese government, and yet another way by independent researchers. Each group creates a discourse shaped by their understanding of the project. Each group’s understandings are molded by their motivations along with the audience that are the recipients of their discourse, all of which creates a different perception of the history of the Three Gorges project. The environmentalists’ history, primarily international non-government organizations such as the International Rivers Network and the Three Gorges Probe, detail abuse by the Chinese government of the natural world and discusses environmental havoc that the dam will wreak on the Three Gorges environment. The Chinese government sees the Three Gorges Dam as a sign of China’s progress and even an attempt to reduce the country’s dependence on foreign countries for fossil fuels and lessen the dependence on coal. Independent researchers take a centrist approach where both the negative and positive aspects of the dam are discussed.
Andrew Whitaker '04 Peter Rogers, Environmental Studies Miad na sine, the Strength of the Storm: Gaelic Songs and Nature in Cape Breton, Since the beginning of human history, people have used culture to orient themselves to their natural surroundings. People in a specific landscape will develop a culture that reflects their landscape and music. My presentation examines this phenomenon in a specific location, Cape Breton Island, Nova Scotia, and demonstrates how Gaelic songs express the changing sense of place that resulted from the migration from Scotland to Canada.
