- This Honors Project investigates the themes of immigration, space, and mobility through the lens of contemporary installation art. It addresses a brief history of global contemporary art, arguing that art of the past two decades has been shaped by preoccupations with and tensions surrounding space. Using the works of Yanagi Yukinori, Alfredo Jaar, and Doris Salcedo as case studies, the essay analyzes how artists use the medium of installation to address institutional history, contemporary geopolitics, as well as individual and collective experience. It interrogates the different aspects of installation art, including temporality, site-specificity, and the use of language, to demonstrate how the medium allows artists to use their own position in the system to critique its inherent limitations.

- This project is an analysis of the effectiveness of five distinct optimization methods in their ability in producing clear images of the basins of attraction, which is the set of initial points that approach the same minimum for a given function. Basin images are similar to contour plots, except that they depict the distinct regions of points--in unique colors--that approach the same minimum. Though distinct in goal, contour plots are useful to basin research in that idealized basin images can be inferred from the steepness levels and location of extrema they depict. Effectiveness of the method changes slightly depending on the function, but is generally defined as how closely the basin image models contour information on where the true minima are located, and by the clarity of the resulting image in depicting well-defined regions. The methods are tested on four distinct functions which were chosen to assess how each method performs in the presence of various challenges. This project ranks the five methods for their overall effectiveness and consistency across the four functions, and also analyzes the sensitivity of the methods when small changes are made to the function. In general, less sensitive and consistently effective methods are more applicable and reliable in applied optimization research.

- Fifteen years into its operation as the preeminent international institution charged with the prosecution of the most serious international crimes, the International Criminal Court (ICC) has faced and continues to face intense backlash from the African continent. Once the Court’s most fervent advocates, many African leaders now lambast the ICC. In recent months, three African countries and the African Union en masse have attempted withdrawal from the Court, thus pushing the ICC-Africa relationship into the international spotlight as a topic of acute global interest. This paper seeks to explore the critiques behind this backlash through both a historical and present-day lens, as well as from the perspectives of African leaders, victims-locals, and civil society actors. In doing so, it investigates historical critiques of the ICTY and ICTR, concerns raised during the Rome Statute negotiations, current African leader perspectives as viewed through the case studies of Darfur, Kenya, Uganda, and the AU-ICC relationship, and present African victim-local and civil society opinions of the Court. By understanding the current and multi-faceted African opposition to the ICC and such criticisms’ historical roots, as well as the pockets of hope for the Court within Africa, this analysis reveals the ICC’s main challenges in its relationship with the African continent. With such hurdles unveiled, the ICC can pursue several strategies, located primarily on the state and individual levels, in its endeavor to address these important critiques and regain African support.

- The O2:CO2 exchange ratio of the terrestrial biosphere (αb) is an important parameter in carbon sink calculations, but its value is not well constrained. We investigate the stoichiometry of O2 and CO2 at Harvard Forest in Petersham, Massachusetts over a span of six years, considering the covariation of O2 and CO2 in forest air during 6-hour periods to determine an average value for the O2:CO2 exchange ratio. This approach provides a way to determine the value of αb averaged across seasonal cycles and species assemblages. Our analysis produces an overall average exchange ratio of -1.06 ± 0.01. Comparing measurements within and above the canopy and during nighttime and daytime periods, we observe that atmospheric dynamics and canopy effects produce lower exchange ratios indicative of an enhanced forest signal at the low intake and for daytime periods. We also see an increase in the exchange ratio in the winter compared to the summer that may reflect changes in plant physiological processes or contamination by a fossil fuel signal. To determine whether our observed ratio is truly representative of αb, we use a simple model to estimate the range of variability in CO2 and O2 mixing ratios expected from local influence alone and use this as a criterion to isolate periods dominated by local exchange, yielding an average summer forest exchange ratio of -1.00 ± 0.02. Our analysis provides insight into the average value and variability of αb for temperate forests for use in calculation of the land carbon sink.

- Central pattern generators (CPGs) are neuronal networks that produce rhythmic motor output in the absence of sensory stimuli. Invertebrate CPGs are valuable models of neural circuit dynamics and neuromodulation because they continue to generate fictive activity in vitro. For example, the cardiac ganglion (CG) of the Jonah crab (Cancer borealis) and American lobster (Homarus americanus) contains nine electrochemically coupled neurons that fire bursts of action potentials to trigger a heartbeat. The CG is modulated by neuropeptides, amines, small molecule transmitters, gases, and mechanosensory feedback pathways that enable flexibility and constrain output. One such modulator, the SLY neuropeptide family, was previously shown to be expressed in hormonal release sites and within the CG itself and has unusual processing features. However, its physiological effect was unknown. Here, I performed dose-response experiments in the crab and lobster whole heart and isolated CG to determine the threshold concentration of SLY neuropeptides to which these systems respond. The crab isoform had strong, excitatory effects in the crab whole heart and weakly modulated the crab CG. The lobster isoform weakly modulated the lobster whole heart and CG. Surprisingly, the crab isoform exerted large, variable effects on the lobster system, which suggests that SLY neuropeptides, their receptors, and their signaling pathways may be evolutionarily conserved across these two species. This research contributes to our understanding of how neural circuits can generate flexible output in response to modulation. It may also offer insight into processes influenced by peptidergic neurotransmission in the nervous systems of other animals, including mammals.

She attended Lewiston public schools and was graduated from Bates College (class of 1971), spending her junior year studying in Switzerland. At the end of 1972, she went to work for Governor Ken Curtis. By September of 1973, she had been hired as part of Senator Ed Muskie’s staff, working first as a caseworker and eventually as his legislative assistant. She attended law school at American University from 1978 to 1981 and transitioned to Senator Mitchell’s staff when he assumed Muskie’s Senate seat. She left Mitchell’s staff in the fall of 1983 and joined the law firm of Preti, Flaherty, Beliveau & Pachios the following June. Her practice has evolved from health law to other political practice issues. She served on the Democratic State Committee from 1986 to 1990 and was a delegate to the 1988 National Convention. Mary Elizabeth McAleney was born on March 18, 1945, in Tuscaloosa, Alabama. Her mother, Helen Irene (Twombly) McAleney, was a Works Progress Administration worker, and her father, William McAleney, was a U.S. Customs officer. Mary came from a strongly Democratic Maine family and was politically active from a young age. She was sent from her home near Vanceboro, Maine, to St. Joseph’s boarding school in South Portland, and from there she went to Merrimac College. After her graduation, she taught high school in Maine, first at St. Joseph’s and then at Catherine McAuley High School. After eight years of teaching, she went into political work. She quickly rose through the ranks during Senator Muskie’s ‘76 campaign and worked for state Senator Jim Tierney. She served in George Mitchell’s U.S. Senate office for ten years (1984-1994), focusing on Maine issues.

- Particle swarm optimization (PSO) is a metaheuristic optimization method that finds near- optima by spawning particles which explore within a given search space while exploiting the best candidate solutions of the swarm. PSO algorithms emulate the behavior of, say, a flock of birds or a school of fish, and encapsulate the randomness that is present in natural processes. In this paper, we discuss different initialization schemes and meta-optimizations for PSO, its performances on various multi-minima functions, and the unique intricacies and obstacles that the method faces when attempting to produce images for basins of attraction, which are the sets of initial points that are mapped to the same minima by the method. This project compares the relative strengths and weaknesses of the Particle Swarm with other optimization methods, namely gradient-descent, in the context of basin mapping and other metrics. It was found that with proper parameterization, PSO can amply explore the search space regardless of initialization. For all functions, the swarm was capable of finding, within some tolerance, the global minimum or minima in fewer than 60 iterations by having sufficiently well chosen parameters and parameterization schemes. The shortcomings of the Particle Swarm method, however, are that its parameters often require fine-tuning for different search spaces to most efficiently optimize and that the swarm cannot produce the analytical minimum. Overall, the PSO is a highly adaptive and computationally efficient method with few initial restraints that can be readily used as the first step of any optimization task.

- Virulence of the gastric pathogen Helicobacter pylori (Hp) is directly linked to the pathogen's ability to glycosylate proteins; for example, Hp flagellin proteins are heavily glycosylated with the unusual nine-carbon sugar pseudaminic acid, and this modification is absolutely essential for Hp to synthesize functional flagella and colonize the host's stomach. Although Hp's glycans are linked to pathogenesis, Hp's glycome remains poorly understood; only the two flagellin glycoproteins have been firmly characterized in Hp. Evidence from our laboratory suggests that Hp synthesizes a large number of as-yet unidentified glycoproteins. Here we set out to discover Hp's glycoproteins by coupling glycan metabolic labeling with mass spectrometry analysis. An assessment of the subcellular distribution of azide-labeled proteins by Western blot analysis indicated that glycoproteins are present throughout Hp and may therefore serve diverse functions. To identify these species, Hp's azide-labeled glycoproteins were tagged via Staudinger ligation, enriched by tandem affinity chromatography, and analyzed by multidimensional protein identification technology. Direct comparison of enriched azide-labeled glycoproteins with a mock-enriched control by both SDS-PAGE and mass spectrometry-based analyses confirmed the selective enrichment of azide-labeled glycoproteins. We identified 125 candidate glycoproteins with diverse biological functions, including those linked with pathogenesis. Mass spectrometry analyses of enriched azide-labeled glycoproteins before and after cleavage of O-linked glycans revealed the presence of Staudinger ligation-glycan adducts in samples only after beta-elimination, confirming the synthesis of O-linked glycoproteins in Hp. Finally, the secreted colonization factors urease alpha and urease beta were biochemically validated as glycosylated proteins via Western blot analysis as well as by mass spectrometry analysis of cleaved glycan products. These data set the stage for the development of glycosylation-based therapeutic strategies, such as new vaccines based on natively glycosylated Hp proteins, to eradicate Hp infection. Broadly, this report validates metabolic labeling as an effective and efficient approach for the identification of bacterial glycoproteins. © 2013 by The American Society for Biochemistry and Molecular Biology, Inc.

- Computer Vision involves the extraction of data from images that are analyzed in order to provide information crucial to many modern technologies. Object recognition has proven to be a difficult task and programming reliable object recognition remains elusive. Image processing is computationally intensive and this issue is amplified on mobile platforms with processor restrictions. The real-time constraints demanded by robotic soccer in RoboCup competition serve as an ideal format to test programming that seeks to overcome these challenges. This paper presents a method for ball recognition by analyzing the movement of the ball. Major findings include enhanced ball discrimination by replacing the analysis of static images with absolute change in brightness in conjunction with the classification of apparent motion change.

- Libyan Jewry and Jews of the Italian peninsula have engaged in near-constant interaction at least as far back as the time of the Roman empire. This project seeks to add to the history of those interactions by discussing Italian Jewish colonial impacts on the Libyan Jewish population. Using ideas of Orientalism and the imagined nation, this project demonstrates how Libyan Jewish identity was shaped by interaction with Italy and how Italian Jews worked colonially to subjugate, define, and change Libyan Jewry. Through analyzing–among other things–newspapers, scholarship, and general Italian Jewish discussion of and interaction with Libyan Jews, I show how Italian Jews (and elite Libyan Jews) worked to Italianize and later ‘Hebraicize’ the Libyan Jewish community..

- The primary goal of this thesis is to bridge two powerful learning paradigms—kernel methods and deep learning—to design novel neural architectures. Kernel methods offer a strong theoretical foundation, in contrast to deep learning, which often operates as a black-box despite its widespread success in real-world applications. In an era where such opaque models increasingly shape the economy and daily life, it is crucial to develop architectures that combine the theoretical clarity of kernel methods with the empirical effectiveness of deep learning. At present, computer scientists largely lead the charge in advancing state-of-the-art models, while many mathematicians work retrospectively to understand why these methods are so successful. A key motivation for this thesis—admittedly a personal one—is the hope that mathematical theory can not only explain existing architectures, but also inspire the development of better ones from the outset.

- In order to maintain circuit stability through environmental perturbations, such as increases in temperature, neural circuits are able to adjust their output via modulatory and ion channel regulation. For instance, peptide modulators enable the lobster cardiac neuromuscular system to sustain physiological function at temperatures that surpass the crash temperature of the organ in the absence of modulation. Crash temperature is defined as the temperature at which neural activity ceases. For a crash, this temperature induced loss of activity is recovered when temperature is returned within the permissible range. Thus, it is hypothesized that there are underlying physiological mechanisms employed by the nervous system that compensates for changes in temperature and provides stability within acute temperature fluctuations. Neuromodulatory mechanisms have been proposed as one hypothesis that provide this temperature compensation. In accordance with previously collected data (Lemus 2022), I hypothesized that myosuppressin, a crustacean neuropeptide, provides stability during acute temperature variations. Because myosuppressin acts on the cardiac neurons and muscles separately, we hypothesized that the myosuppressin-induced increase in heart contraction amplitude, and decrease in contraction period can offset each other to provide system stability as temperature is increased. To test whether or not myosuppressin stabilizes circuit output as temperature is increased, myosuppressin was applied to the lobster whole heart at 7ºC, 10ºC, 13ºC and 16ºC, for 20 minutes. Changes in cardiac output in response to temperature and modulation were assessed by measuring the contraction force, heart beat frequency, and minimum contraction force. Interestingly, and contrary to previous results, in this data set, the cardiac neuromuscular system was temperature compensated in saline alone (control), and was not temperature compensated when perfused with myosuppressin (10-6 M). These findings seemed to differ from Lemus’ data (2023), where the cardiac neuromuscular system was not temperature compensated in control conditions and became temperature compensated when perfused with myosuppressin. The seasons at which each data set was collected (June-August vs November-March) could underlie these observed discrepancies.

- The Maine Mobile Health Program is a federally qualified health center and community health organization that provides healthcare to migrant and seasonal farmworkers in rural Maine. The MMHP employs community health workers to act as negotiators between unjust systems, physicians, and patients. This thesis investigates the ways in which community health workers provide patients with “empathic care” and details how this happens in practice based on field observations and interviews. It also addresses how empathic care benefits patients by creating empowerment, building trust, and giving patients agency in their healthcare decision making. Furthermore, this thesis discusses the cost of providing empathic care as “moral injury” and considers how community health workers are emotionally and psychologically impacted by the work that they do. Ultimately, this thesis illuminates the transformative capacity of empathic care and the burden it imposes on community health workers operating within inequitable systems.

- This honors project explores how Wabanaki scientists navigate and reshape dominant paradigms of science, land use, and education by strategically integrating Western science with Traditional Ecological Knowledge. Through theoretical and historical analysis alongside three ethnographic interviews, I show how Indigenous knowledge is not simply surviving within colonial systems but actively transforming them from within. Framing the work through the concept of etuaptmumk (two-eyed seeing), I examine how my interviewees—Dr. Suzanne Greenlaw, Sam St. John, and Tyler Everett—use science as a relational, spiritual, and community-based practice to support cultural continuity and natural resource protection. Their work challenges the dominant binaries between science and religion, objectivity and identity, and knowledge and responsibility. They engage with Western institutions on their own terms to support their communities and uphold Wabanaki sovereignty. While the work of Indigenous scientists is increasingly studied across the U.S. and globally, Wabanaki communities remain underrepresented in this discourse. This project helps fill that gap and calls on Bowdoin College to invest more seriously in reciprocal relationships with Wabanaki communities, including institutional collaboration and the hiring of Indigenous faculty.

- The Revolutionary Body traces three Marxist feminist groups which emerged in the late 1960s and organized through the 1970s: Wages for Housework, the Third World Women’s Alliance, and WITCH. These three groups have yet to be combined in secondary historical scholarship, and their grouping here evidences similarities in anti-capitalist organizing across demographic differences. This project delves into the groups’ conceptions of the home and the body as dual sites of oppression and sources of liberation. Through studying such issues as imprisonment, housework, and forced sterilization, this project uncovers the intensity of capitalist violence unto the body and the ensuing mysticism revolutionary women’s bodies were seen to hold.
