Characteristics And Motivations Of Passengers On Board A Puffin Tour Boat In Maine, Skye Howard

Honors College

The Atlantic puffin (Fratercula arctica) is a visually attractive seabird found in the North Atlantic Ocean. While research in the Eastern North Atlantic indicates that Puffins attract visitors to areas where the species can be viewed, less is known about visitor interest in Atlantic puffins in the Western North Atlantic. This study helps fill a gap in the literature regarding visitor interest in Atlantic puffins in the Western North Atlantic. The purpose of this study is to provide an understanding of the characteristics of passengers on board a puffin tour boat visiting Petit Manan Island, Maine, and the importance of …

Using The Tarot To Heal: A Study Of The Use Of Tarot In Therapeutic Settings And The Creation Of A Major Arcana, Venae Demarte

Honors College

The purpose of this project is to determine whether the use of Tarot has merit in clinical use of mindfulness techniques. Both mindfulness and Tarot alike have been used to help those who struggle with their mental health (Nehra, et al., 2013; Semetsky, 2010). This study aims to combine these two notions by researching the use of Tarot readings as a mindfulness technique.

With Tarot already being used as a healing method to those who are open to its use, it makes sense to bring Tarot into a more empirical light, rather than limit its use to those who are …

Creating Interpretable Deep Learning Models To Identify Species Using Environmental Dna Sequences, Samuel Waggoner

Honors College

This research aims to develop an interpretable and fast machine learning (ML) model for identifying species using environmental DNA (eDNA). eDNA is a technique used to detect the presence or absence of species in an ecosystem by analyzing the DNA that animals naturally leave behind in water or soil. However, there can be millions of sequences to classify and the reference databases are sizeable, so traditional methods such as BLAST are slow. Convolutional neural networks (CNNs) have been shown to be 150 times faster at classifying sequences. In this work, we create a CNN that achieves 92.5% accuracy, surpassing the …

Effects Of Ecologically Relevant Concentrations Of Nitrate On Behavior In Betta Splendens, Sarah Janson

Honors College

Nitrate is a ubiquitous pollutant that is becoming more prevalent in both fresh and saltwater environments. Short term effects are often studied, but an organism’s response to stress can change due to whatever the stressor is. In order to research this, a study was run using environmentally relevant nitrate treatments (0 mg/L, 10 mg/L NO3-N, and 100 mg/L NO3-N) to see the effect of nitrate on scototaxis behaviors, a measure of anxiety. This study used Betta splendens because they are easy to rear and have very well documented behaviors. In addition to the scototaxis, the effect of temperature on mortality …

Winging It Through Unprecedented Times: A Study Of Avian Admissions To Wildlife Rehabilitation Centers In The Eastern United States Amidst The Covid-19 Pandemic, Thea Tengstrom

Honors College

The onset of the COVID-19 pandemic in 2020 has brought new research that examines the many ways in which humans impact wildlife. Wildlife rehabilitation is a tool that attempts to mitigate some negative effects of anthropogenic activity (domestic cats, window strikes), through specialized care to aid injured and orphaned animals. This study sought to investigate if the ‘Anthropause’, which saw a massive change in human behavior, demonstrated an influence on wild bird admissions to wildlife rehabilitation centers. Twelve centers were selected including both urban and non-urban centers throughout the eastern United States. Bird admission data between 2018 and 2021 were …

Ghost Connect-Net: A Connectivity-Based Companion Network To Enhance Pruning Methods, Mary Isabelle Wisell

Honors College

Deep neural network (DNN) approaches excel in various real-world applications like robotics and computer vision, yet their computational demands and memory requirements hinder usability on advanced devices. Also, larger models heighten overparameterization risks, making networks more vulnerable to input disturbances. Recent studies aim to boost DNN efficiency by trimming redundant neurons or filters based on task relevance. Instead of introducing a new pruning method, this project aims to enhance existing techniques by introducing a companion network, Ghost Connect-Net (GC-Net), to monitor the connections in the original network. The initial weights of GC- Net are equal to the connectivity measurements of …

Determining The Viability Of Marine Sensor Construction, Roman Sequeira

Honors College

I intend to determine the viability of building a sensor that can be deployed in marine environments. Viability is defined as a summary of economic affordability, practicality of construction and deployment, knowledge required, and effectiveness. In order to get the best results, our sensor must be able to be modified to suit individual circumstances, constructed out of easy to obtain materials, be robust enough to withstand less than lab grade environments, and most importantly function well enough to be worth the effort of building it. I have built a sensor using the cheapest and most widely available options available. It …

Sexuality Education In Central Maine High Schools: What's Happening Now And What's Changed In Two Decades?, Morgan Inman

Honors College

This qualitative study aimed to examine sex education in Central Maine high schools. Through interviews with seven teachers who are directly involved in instruction, this study sought to understand the current state of sex education in those schools. Interviews with teachers explored their background and experience, as well as their goals, the topics they cover, and any other sexuality-related programs or services available in their schools. Findings from these teacher interviews were compared to those of a similar study conducted over two decades earlier to look for trends and changes across time. Finding revealed that teachers share many of the …

The Impact Of Prejudice On Women's Wellbeing: A Moderated-Mediation Rejection Identification Model On Feminist Identity, Liana Shaw

Honors College

The study’s purpose was to assess sexism’s impact on women’s wellbeing based on the Rejection-Identification Model (Branscombe et al., 1999), in which perceived prejudice increases group identification, which in turn buffers the negative consequences of prejudice on wellbeing. Surveys were administered via Qualtrics. Using PROCESS analyses in SPSS, Study 1 (n = 1,083) investigated whether or not these relationships between prejudice, group identification, and wellbeing were moderated by feminist identity (Model 59; Hayes, 2018). Results showed that while women higher in feminist identity do experience greater depression in response to perceived prejudice, they also have a significantly stronger relationship between …

Decadent Gothic: The Horrors Of An Urban World, Kyle Willis

Honors College

The purpose of this thesis is to analyze and understand the rapid popularity of horror literature in the 1880s and 1890s through a literary style known as decadent Gothic. To do this, I will analyze two keystone texts of the style: Robert Louis Stevenson’s 1886 novella, Strange Case of Dr Jekyll and Mr Hyde, and Oscar Wilde’s 1891 novel, The Picture of Dorian Gray. This analysis will be done using a framework of London’s nineteenth-century urbanization to understand the represented fears in both texts. This thesis shows that urbanization created a decentralized environment full of frightening stimuli, and that decadent …

Evaluating The Effects Of Parasite Infections On Reproductive Ability In Maine Moose, Isabella Costa

Honors College

Despite conservation efforts, moose have experienced increasing mortality rates. Winter ticks are known to cause anemia and lower reproductive potential in moose. Moreover, a genus of bacteria, Anaplasma spp., is known to cause a reduction in reproductive efforts in other animals, such as cattle. Because both winter ticks and Anaplasma spp. may affect female reproductive ability, the overall goal of this research was to determine if Anaplasma bacterial infections could be impacting female moose reproduction within the state of Maine. To address this, samples and biological data from moose were collected during hunter harvest, in collaboration with hunters and the …

This manuscript is meant to engage children with the environment around them by introducing them to simplified scientific concepts using references …

Exploring Non-Traditional Assessments For Use In High School Stem Courses, Gwenneth Turgeon

Honors College

Summative and Formative assessments are essential aspects of education and have been for many years (Guskey, 2005). The use of assessments helps educators check in with students to see where they fall in terms of understanding content and where they could use additional help. Formative assessments are used more to assess students' understanding as they learn the topic (Bloom et al., 1971). In contrast, summative assessments represent the student's mastery of the topic. This text explores and examines a form of summative assessment that uses something other than what has been determined to be the traditional assessment tools, such as …

A Phenomenological Approach To Classic Maya Kingship, Griffin Dever

Honors College

The aim of this Honors Thesis project is to describe the experience of the Maya kingship of the Classic period and its role in Maya culture. The thesis takes a phenomenological approach and draws primarily on the work of Maurice Merleau-Ponty, Martin Heidegger, John Russon, and Walter Benjamin. The archaeological record of the Maya world, especially the city of Palenque, is the primary resource upon which this analysis is based, including monumental art and public architecture, ritual, courtly art and stonework, and stelae. However, some focus is also given to existing background literature to provide the reader with some historical …

Ecological, Molecular, And Electron Microscopical Investigations Of The Distribution Of Shell-Boring Polychaetes Along The Coast Of Maine, Emma Tomasetti

Honors College

Blister worms are polychaete worms that live in various calcareous materials such as dead shells, red algae, limestone, and cinder blocks, along with cultured shellfish, such as oysters or sea scallops. These worms can be considered a pest due to their nature to burrow into their host’s substrate and create blisters that then fill with mud and detritus. In chapter 1, I worked closely with an oyster farm looking at the reproductive status of one species of blister worm, P. websteri, and the efficacy of cold storage as a method of ridding oysters of P. websteri. For chapter 2, I …

Understanding The Connection Between Water, Fish, And Pfas Concentrations: Implications Of Fish Diet And Species-Specific Variability, Ece Yeldan

Honors College

Perfluoroalkyl and polyfluoroalkyl substances, commonly known as PFAS or “forever chemicals,” have emerged as a significant concern for both human health and the environment. These persistent compounds permeate various aspects of commerce, leading to widespread exposure and the cycling of these compounds through environmental feedback routes. Among the sources of exposure to humans, fish consumption stands out prominently. Recreational and sustenance fishing, cherished by Maine residents and indigenous communities alike, underscores the need to comprehend PFAS dynamics in fish and water. To explore the variability of PFAS accumulation in fish, water, and sediment, I conducted a comprehensive literature review. The …

Playing History: How Video Games Can Change The Way We Understand The Past, Chapman Hall

Honors College

Video games are a wildly popular and growing form of art and entertainment. Yet they are often overlooked within academic fields like history. This thesis examines the unique qualities of video games that make them powerful tools to understand history in a different manner. The interpretative frameworks of simulation and agency are central to this analysis, and they are applied to the history-based video game Europa Universalis IV as a case study of how video games facilitate rich and rewarding historical sensibilities that deepen the connection between past and present, a long-standing goal of professional and popular historians. The study …

Sustaining Community And Identity Through Food At The University Of Maine, Elizabeth Dudevoir

Honors College

International students often travel thousands of miles to attend the University of Maine. Foodways become a way to sustain one’s communal and self-identity. Food is more than nourishment: certain dishes also tell stories and become building blocks for conversation. Here, I focus on how international students use food as a vehicle to build community and understand the role of food to comfort and engage individuals. I also consider access to culturally significant ingredients, as the greater Orono/Bangor area lacks markets and stores that carry certain products. Through interviews, individuals shared their foodways and experiences as international graduate students at the …

Using Cdom Optical Properties To Estimate Its Source, Distribution, And Doc Conentration In Maine Estuaries, Camille Michaud

Honors College

Colored dissolved organic matter (CDOM) contributes largely to ocean color, and therefore, influences processes and applications that interact with light in the ocean such as remote sensing and biogeochemistry. It is a component part of dissolved organic carbon (DOC) and there is a strong relationship in coastal waters between CDOM absorption and DOC concentration. CDOM optical properties also vary with salinity and source. These important aspects of CDOM absorption led us to collect CDOM samples across the salinity gradients of 3 estuaries in Maine: the Penobscot, Damariscotta, and Sheepscot. We sampled stations along the salinity gradient in each estuary from …

A Survey Of Current Perceptions And Actual Use By Students And Faculty Of Generative Artificial Intelligence In Higher Education, Cameron Hasselbaum

Honors College

Generative AI as an emerging new technology may have large-scale impacts on how business is conducted and how schools teach students. OpenAI released ChatGPT to the public in November of 2022. Two similar surveys were conducted one year after ChatGPT was released in December 2023 to measure the perceptions of generative AI and changes in behavior in the academic space among students and faculty at the University of Maine. The survey findings were that student respondents have been quicker to adopt and find utility in the new technology. Still, it has yet to be readily adopted for use as widely …

Does Urbanization Surrounding Stopping Sites Affect Migratory Behavior In American Woodcock (Scolopax Minor)?, Zoe Pavlik

Honors College

Urban landscapes may influence bird species in complex ways, with some species exploiting urban environments, others adapting to them, and others avoiding them. Migratory birds encounter urbanization not just during breeding and overwintering, but also at stopping sites during migration. Migration routes of American Woodcock (Scolopax minor), a bird species experiencing long term population declines, follow the east coast of the United States, including the major urbanized areas of the eastern seaboard. I explored the effects of urbanization around stopping sites on Woodcock migratory behavior using the percentage of impervious surfaces within a buffer surrounding the site as a measure …

What Is Marxian Communism? Limning The Post-Revolutionary Utopia By Implication, Teodora Blejeru

Honors College

This thesis aims to discover the facts of Marxian communism by implication. By analyzing the works of Marx, this project outlines the contradictions within capitalism and explains how these problems will be solved within Marxian communism. This pro- ject explains historical materialism and how it can be used to explain Marxian com- munism as not only the end of history, but as the end of class antagonisms. It also aims to explain why twentieth century communist regimes cannot be considered truthful exam- ples of Marxian communism. After the introductory chapter, the thesis analyzes The Communist Manifesto, The German Ideology, and …

Why Do Rebel And Criminal Groups Provide Social Services?, Sydney Lorom

Honors College

This work analyzes the approaches taken by rebel and criminal groups to provide social services to the geographic regions they control. It presents the case studies of a rebel organization, Hezbollah in Lebanon, and a former criminal group, the Medellin Cartel of Colombia. My comparison between these armed non-state actors is intended to explore why rebel and criminal groups respond to the needs of citizens within the boundaries of their control in various ways, as well as understand what factors primarily shape differing approaches. Possible explanations for the extent of a group’s responses are presented after distinguishing the operation styles …

Autonomous Fish Identification For The Remotely Operated Vehicle Control System, Jacob Wildes

Honors College

A Remotely Operated Vehicle was designed, constructed, and programmed as a senior design project in Electrical and Computer Engineering by Dyllon Dunton and Jacob Wildes. The system was intended to be an alternative means to inspect the underside of ships. Given the small footprint of the system, it can be easily extended into other applications. In this thesis project, the observation system is modified to detect if a fish is present or not, classify the species, localize where in the image the fish is, and mask the fish by separating fish pixels from non-fish pixels. Additionally, the original design will …

Investigation Of How A Kinesin-1 Mutation Affects The Synaptic Localization Of The Periactive Zone Protein Apt-4, Ian Harden

Honors College

Dysfunctional or loss of synaptic transmission is a major contributing factor to many neurological and neurodevelopmental diseases, such as Alzheimer’s disease. To develop novel approaches to treating these diseases, understanding the structures and proteins related to synaptic development and function is essential. Within the synapse is the presynaptic site, containing the active and periactive zones, at which synaptic vesicles containing neurotransmitters are released. The active zone’s primary role is mediating neurotransmitter release via exocytosis, and the periactive zone sorts and recycles synaptic vesicles via endocytosis. However, how periactive zone proteins localize to the presynapse and how they interact with the …

The Permaculture Discussion Group: Participatory Learning For Community Connection And Systems Transformation, Belu Katz

Honors College

There is a need in our society to have a more holistic understanding of the polycrisis, the intertwining of environmental and social crises that create compounding effects, and the underlying issues that have temporarily and psychologically separated humans from our local ecosystems and biophysical limits. This requires creating space to deeply discuss these issues and possible responses. Permaculture is an ethical framework for designing regenerative and resilient human systems that work within, instead of against, nature. The Terrell House Permaculture Living & Learning Center is a student housing project where four resident stewards run the Permaculture & Gardening Club (PGC) …

The Man-Hating Woman: Studying Bystander Perceptions Of Social Media Sexism Confrontations, Erika Hipsky

Honors College

Social media platforms enable users to perpetuate discriminatory rhetoric and oppressive structures, including sexism. While previous research on sexism confrontations has mainly focused on face-to-face interactions, there is little information available on how confrontations operate within the context of social media. This thesis examines the influence of confronter approach (HATE or CARE) and identity (man or woman) on TikTok sexism confrontations. Female participants, acting as bystanders (N = 57), were surveyed on their perceptions of four TikTok confrontations: HATE Woman, CARE Woman, HATE Man, and CARE Man. Regardless of confronter gender, participants viewed CARE confrontations as more likable than HATE …

Assessing The Influence Of Interseeded Cover Crops On Beneficial Arthropod Abundance In A Northeastern Agroecosystem, Charles Cooper

Honors College

Conservation agriculture approaches are gaining traction as the planet’s food system grapples with climate change, oil depletion, and rampant environmental degradation (Palm et al., 2014). Cover cropping is an integral practice of conservation agriculture. Ground dwelling arthropods play an important role in agroecosystems, providing ecosystem services including seed predation and nutrient cycling. Because the relationship between cover crops and arthropod abundance are likely influenced by management conditions, I investigated arthropod abundance in a field interseeded with cover crops on a research farm in Maine, United States. Interseeding is an emerging practice in the northeastern United States, with potential to address …

Ecological Effects And Ethics Of A Species Range Shift To High Elevation Ponds, Ava Ardito

Honors College

As temperatures warm, the climate crisis is having a significant influence on species across the world and altering their distributions. Colorado's high elevation ponds have recently observed a species range shift, traveling to higher altitudes than they have previously inhabited. The Mexican Cut Nature Preserve near the Rocky Mountain Biological Laboratory (RMBL) in Gothic, CO, is home to a prominent caddisfly Limnephilus externus, but recently a new range-shifting species, Nemotaulius hostilis, has appeared. Caddisflies play an essential role in nutrient cycling and putting energy back into the food web. The range-shifting species is known to excrete high rates of phosphorus …
