Horses: How Saddle Style Defines A Culture And The Skeletal System, Elizabeth Brandon
Horses: How Saddle Style Defines A Culture And The Skeletal System, Elizabeth Brandon
Honors Theses
Throughout history different cultures have been greatly impacted by horses and their uses. Today horseback riding is still a very popular sport, and though it is more dangerous than other forms of transportation, such as motorcycle riding, horseback riding is still used in entertainment, occupational, and leisure activities. Saddles have long been an important piece of equipment for riding. As the horse became a mode of transportation, many cultures had their own saddle style, but today there are two prominent saddle styles, the western and english styles. The western saddle style is used more for leisure, occupational, and rodeo riding. …

An Undiscovered Wilderness--Place And Self: A Digital Curation Of Text And Images, Alana Jane Jajko
An Undiscovered Wilderness--Place And Self: A Digital Curation Of Text And Images, Alana Jane Jajko
Honors Theses
Medieval manuscripts are beautiful compilations of text and image. My work explores this media as a way to celebrate the beauty of the natural world, combining nature writing with marginalia and illustrations that reflect the content of the text. The calligraphy style is modeled after the font used in the Book of Kells, as it too portrays natural imagery throughout its pages. Manuscripts were meant to glorify the text within, and it is my hope to glorify and preserve an appreciation of nature in a world where it is sometimes overlooked. The culmination of this research has grown into a …

The Growing Crisis In Maine: Neonatal Abstinence Syndrome, Olivia Avidan
The Growing Crisis In Maine: Neonatal Abstinence Syndrome, Olivia Avidan
Honors Theses
Neonatal Abstinence Syndrome (NAS) is a Maine epidemic. In addition to having medical repercussions, NAS is intrinsically linked to social, political and economic factors. NAS is a conglomeration of symptoms, short-term and long-term, that affect a child that has been exposed to opioids in utero. These factors that impact NAS are interdependent. The past decade is characterized by a dramatic rise in NAS cases in Maine. This paper explores the social, political and economic landscape surrounding NAS in an effort to describe fully the syndrome’s effect on both individuals and the community as a whole.

Spatial Cognition And Emotion Recognition As A Function Of Asd, Catalina Cumpanasoiu
Spatial Cognition And Emotion Recognition As A Function Of Asd, Catalina Cumpanasoiu
Honors Theses
Past research shows that although autism has among its particularities a tendency for lower results on cognitive tasks, especially on the executive functioning skills, people with ASD perform equally well, and sometimes even better than controls on tasks for visuo-spatial cognition. However, there is also evidence suggesting that people on the spectrum might have an impaired emotion recognition mechanism. In addition, there is research on spatial cognition and affect, looking at how emotions provoked by stimuli can change the way in which we perceive the space. In the current study, we will look at spatial cognition and emotion recognition as …
Development Of A Genetic Over-Expression System For The Freshwater Sponge Ephydatia Muelleri, Joe Walsh
Development Of A Genetic Over-Expression System For The Freshwater Sponge Ephydatia Muelleri, Joe Walsh
Honors Theses
The aim of this work is to develop an over-expression system for Ephydatia muelleri. Preliminary work by Klaske Schippers (Schippers, 2013) showed sponges were induced to transcribe reporter genes driven by the widely used cytomegalovirus promoter (CMV). Building off Schippers work, newly identified native Ephydatia promoters were identified from the genome and verified to drive expression ofreporter genes. Validated over-expression vectors and transfection technology will allow researchers around the world who are working with this organism to ask questions about cell specification, gene regulation and animal development.
Windows Into Changing Worldviews: A Critical Cartographic Analysis Of Four Influential World Maps From The 13th To The 21st Century, Elizabeth E. Wicks
Windows Into Changing Worldviews: A Critical Cartographic Analysis Of Four Influential World Maps From The 13th To The 21st Century, Elizabeth E. Wicks
Honors Theses
It is an inherent part of human nature to seek knowledge of the world around us. As knowledge of the world grew, so did the need for its visual representation — thus came the introduction of the map into society. The map is a technology that allows us to see an expansive view of the world around us and to understand our own place in the world. In the past, displaying a full view of the world was more of a challenge — many regions remained unexplored or undiscovered. The mapmaker was given the task of representing both known and …
Spatial Variation Of Bacterial Communities On The Leaves Of Southern Magnolia Trees, Heather L. Valdin
Spatial Variation Of Bacterial Communities On The Leaves Of Southern Magnolia Trees, Heather L. Valdin
Honors Theses
Bacteria are found in almost all environments on earth, including on the surface of other living things. Bacteria that exist on the leaves of plants (the phyllosphere) are of interest because of the potentially harsh nature of the environment they inhabit, and of applied interest. Although there has been a substantial amount of research in phyllosphere microbiology, few studies have examined the effect of spatial variation on phyllosphere community composition. This project investigated the effect of spatial variation on the bacterial communities living on the surface of Magnolia grandiflora leaves. Following DNA extraction, next generation sequencing of 16S rRNA gene …
A Visualization Tool For Survey Responses And A Unifying Interface Redesign, Iva Cramer
A Visualization Tool For Survey Responses And A Unifying Interface Redesign, Iva Cramer
Honors Theses
As an intern for financial software company FNC, Inc. during the summer of 2014, my fellow interns and I began an innovation project for creating and analyzing surveys for better client feedback methods. I have continued this project even after the internship, and this thesis covers that continuation: the visualization of survey responses and the redesign of the page on which they are contained. The project detailed here was to revamp the survey statistics page with a coherent layout that matches the rest of the site in addition to overhauling the actual graphs and charts for aesthetic and accuracy.

The Effect Of A Neurotoxic Dose Of Methamphetamine On Attention And Response Learning In The Rat, Anja Kremer
The Effect Of A Neurotoxic Dose Of Methamphetamine On Attention And Response Learning In The Rat, Anja Kremer
Honors Theses
High doses of methamphetamine (neurotoxic doses) have been shown to have an effect on both attention and response learning. In previous literature, meth rats were found to have higher reaction times, and therefore, it has been concluded that meth may cause a deficit in response learning. Our study, using modal initiation time as a measure of response learning, found no effects of methamphetamine or training condition on mode. Studies have also shown positively skewed reaction time distributions, which have been defined as attentional lapses. Our experiment used DevMode to measure these lapses. Although meth did not, training condition did have …
Secondary Metabolites Isolated From Perovskia Atriplicifolia And Their In Vitro Binding Affinity For Human Opioid And Cannabinoid Receptors, Ashli Fitzpatrick
Secondary Metabolites Isolated From Perovskia Atriplicifolia And Their In Vitro Binding Affinity For Human Opioid And Cannabinoid Receptors, Ashli Fitzpatrick
Honors Theses
Plants and their natural products have been utilized for thousands of years in the treatment of many human diseases. Because of their structural diversity, natural products are ideal lead compounds for drug development. In this thesis, the natural products of the plant Perovskia atriplicifolia were investigated, specifically their in vitro binding affinity to receptors in opioid and cannabinoid classes. Extracts that demonstrated good selective opioid and cannabinoid receptor binding were subjected to bioassay-guided fractionation. Four active compounds were identified from the crude extract in Perovskia atriplicifolia: 1) 5-hydroxy-3',4',6,7-tetramethoxy flavone, 2) 5,7-dihydroxy-3',4',6,-trimethoxy flavone, 3) 5-hydroxy-4',6,7-trimethoxy flavone, and 4) 5,7-dihydroxy-4',6,-dimethoxy flavone. Each …

Based on an extensive bibliography of primary and secondary sources*, this thesis explores three common components that manifest themselves …
Exploration Of Cannabinoid And Opioid Agents From Plants Used In Traditional Medicine, John Fitzpatrick
Exploration Of Cannabinoid And Opioid Agents From Plants Used In Traditional Medicine, John Fitzpatrick
Honors Theses
Ten plants, with known medicinal uses, were gathered to study for their possible production of secondary metabolites that act as opioid and cannabinoid agents. All plants were subjected to in vitro bioassays testing for their affinity for the opioid and cannabinoid receptors. Banisteriopsis caapi extracts displayed the greatest affinity for both opioid and cannabinoid receptors. B. caapi extracts underwent column fractionation yielding fractions that were subjected to further in vitro studies. We discovered that the ethanolic extract of this plant (foliage) binds to all three opioid receptors (µ, κ and δ) and cannabinoid receptors (CB1 and CB2) with values ranging …

X-Dimer Mutations And Their Effects On The Folding Stability And Assembly Of Ecad12 At The K14-D138 Interface, Martha Kaitlyn Coghlan
X-Dimer Mutations And Their Effects On The Folding Stability And Assembly Of Ecad12 At The K14-D138 Interface, Martha Kaitlyn Coghlan
Honors Theses
Classical cadherins were first identified by their function in mediating calcium-dependent cellular adhesion and constitute a large family of cellular adhesion receptor proteins whose differential binding is central to the development and maintenance of tissue architecture. The interface underlying the binding interaction reveals that all classical cadherins share a common adhesive interface in which the portion of the β-A strand closest to the N-terminus is swapped between EC1 domains of the adhesive partner protomers. A second dimeric configuration, known as the 'X-dimer', is the face-to-face association of two protomers in which their orientation is dictated by three symmetrical noncovalent interactions …

In Vino Veritas: A Comparison Of Organic Winemaking And Attitudes Towards Organic Wine In Four Global Regions, Mary Sloan Merkel
Honors Theses
Organic winemaking is a very high value adding activity for the economy, but the industry has seen different levels of growth throughout the world. It is unclear whether organic winemaking is a viable long-term activity in prominent winemaking regions. This thesis looks at the regulations dealing with organic winemaking and attitudes towards organic wine in four major wine producing areas in the world: the United States, Italy, Argentina, and New Zealand. This thesis uses an extensive literature review of existing studies and papers dealing with organic wine, as well as government regulations and private standards to determine the current practices …
Honestly, Woman, You Call Yourself Our Mother?: Mothers And Witches In Harry Potter, Mary-Eileen Rankin Rankin
Honestly, Woman, You Call Yourself Our Mother?: Mothers And Witches In Harry Potter, Mary-Eileen Rankin Rankin
Honors Theses
This thesis aims to analyze the importance of maternal nurture and the witches as mothers trope in the Harry Potter series. This nurture is traditional as well as perverse and appears in characters besides the adult women. Rowling creates characters who appeal to paradigms of the Early Modern bad mother witch who harmed children among other accusations associated with female sexuality and motherhood. Additionally, Rowling challenges the negative stereotype of associating witches and bad mothering by presenting witches as good mothers. The power of maternal nurture in the series is best seen through the good mothers. This theme plays such …
Understanding The Implications Of Climate Change For Birds Of The Family Phasianidae: Incorporating Fleshy Structures Into Models Of Heat Dissipation Capacity, Megan L. Smith
Honors Theses
Though widespread acceptance of global warming has generated a plethora of studies evaluating the potential responses of species to increased temperatures, until recently, species and genus-specific studies were not common and for many taxa such studies have yet to be completed. One particularly understudied group in this regard is the avian order Galliformes. In this study, I focus on the tribe Phasianidae. Furthermore, most studies evaluating the potential range changes of species in response to a changing climate fail to account for the ability of organisms to adapt to the changing climatic conditions, either via plastic adaptations or genetic adaptations. …
The Effects Of Acoustic Signals On The Endocrine Physiology Of Female Green Treefrogs, Hyla Cinerea, Melissa Paige Dent
The Effects Of Acoustic Signals On The Endocrine Physiology Of Female Green Treefrogs, Hyla Cinerea, Melissa Paige Dent
Honors Theses
The vocalizations of male H. cinerea stimulate cortisol production in male receivers during close-range interactions. In many vertebrate species, males and females possess similar sensory neuroendocrine pathways, suggesting that acoustic signals may also stimulate CORT production in females. Males of this species would potentially benefit from stimulating CORT production in females because elevated CORT levels significantly decrease the strength of female preferences for energetically costly calls (i.e., calls produced at rapid rates). The primary objective of my honors research was to assess how the acoustic signals produced by male green treefrogs, Hyla cinerea, influence the endocrine physiology of female signal …
A War On Women? The Malleus Maleficarum And The Witch-Hunts In Early Modern Europe, Morgan L. Stringer
A War On Women? The Malleus Maleficarum And The Witch-Hunts In Early Modern Europe, Morgan L. Stringer
Honors Theses
This thesis explores the topic of gender and witchcraft, specifically why women were so heavily represented in witchcraft trials. The demonology text, The Malleus Maleficarum was analyzed. Several other demonological texts were also analyzed and then compared to one another regarding their statements about women, men, and witchcraft. Then historiography pertaining to gender and witchcraft were analyzed and critiqued. The Malleus Maleficarum contains a high degree of misogyny, but it presents an extreme misogynistic view that is not present in other demonology texts. The argument that the Early Modern European Witch-Hunts were a war on women fails to account for …
A Global Perspective On Ethical Consumerism: A Study Of Advertisements From Social Enterprises To Identify The Ethical Consumer, Murray Miller
A Global Perspective On Ethical Consumerism: A Study Of Advertisements From Social Enterprises To Identify The Ethical Consumer, Murray Miller
Honors Theses
This paper explores ethical consumerism in the United States and Latin America. I examined ethical consumerism in these two settings by identifying social enterprises from different countries in each setting to identify the ideal ethical consumer. After comparing and contrasting the ethical consumer in each context, I determined that ethical consumerism does exist in Latin America. According to scholarship, a country must be postmaterialist in order for ethical consumerism to exist. Through my research, I concluded that Latin America is postmaterialist, therefore ethical consumerism does exist.
Effect Of Atomoxetine On Attentional Lapses: An Animal Model, Pooja Chawla
Effect Of Atomoxetine On Attentional Lapses: An Animal Model, Pooja Chawla
Honors Theses
Atomoxetine (ATX) is a non-stimulant drug that has been used to treat symptoms of ADHD, including lapses of attention. These attentional lapses are depicted as a longer, positive skew in a reaction time distribution comprised of a normal and an exponential curve. The central tendency is thought to represent sensory-motor processing; while the positive skew is thought to be caused by attentional lapses in animal models. This positive skew is larger in individuals with ADHD and is thought to be a result of an increased number of attentional lapses. In the animal model used in this experiment reaction time is …
The Effects Of Testosterone On Calling Behavior In Green Treefrogs, Hyla Cinerea, Brandon Bunol
The Effects Of Testosterone On Calling Behavior In Green Treefrogs, Hyla Cinerea, Brandon Bunol
Honors Theses
Circulating androgen levels can have a profound effect on the expression of elaborate male traits and courtship behaviors that are important in attracting females. For example, elevated androgens are necessary for the expression of vocal displays used by male anurans (frogs and toads) to attract mates. However, the nature of the relationship between androgen levels and the extent, or magnitude, of vocalization in male anurans is unclear. For example, androgens may have a threshold effect on vocalization wherein elevation in androgens is required for vocal expression, but elevations above threshold do not mediate an increase in the magnitude or extent …
Androgen Mediation Of Elaborate Male Traits: The Effects Of Dihydrotestosterone Administration On Vocal Quality In Male Green Treefrogs, Hyla Cinerea, Thor M. Goodfellow
Androgen Mediation Of Elaborate Male Traits: The Effects Of Dihydrotestosterone Administration On Vocal Quality In Male Green Treefrogs, Hyla Cinerea, Thor M. Goodfellow
Honors Theses
Elevated androgen levels are well known to mediate the expression of male courtship behaviors and elaborate traits, but whether androgens act via threshold or graded effects is less clear. Models linking elaborate male traits to the endocrine system often assume that androgens have a graded effect on the magnitude or extent of elaborate male traits and that female preference for more elaborate male traits thus drives concordant directional selection on circulating androgen levels. To test this hypothesis, I examined the effects of dihydrotestosterone (DHT) administration on the quality of advertisement calls produced by male Hyla cinerea. Advertisement calls are an …
Redefining The Insular Tradition: Illuminated Manuscripts Of The Seventh Through Ninth Centuries, William Boyles
Redefining The Insular Tradition: Illuminated Manuscripts Of The Seventh Through Ninth Centuries, William Boyles
Honors Theses
During my studies as an undergraduate student with an interest for medieval art, I found myself drawn to the beautifully painted works of illuminated manuscripts. Especially interested in the history, culture, and tradition of the British Isles, I became intrigued by the oftentimes-interchangeable term Insular. Textbooks, scholars, and various journal articles that I read all viewed Insularity in a slightly different light. So when given the chance to explore a unique topic for my honors thesis, I immediately knew that I had to research this problematic designation. My research began with a broad reading of the core of books, journals, …

Sandy Symbionts: How Tree Identity Shapes Ectomycorrhizal Fungus In Sand Pine, John Culbertson
Sandy Symbionts: How Tree Identity Shapes Ectomycorrhizal Fungus In Sand Pine, John Culbertson
Honors Theses
The purpose of my thesis was to investigate the structure and composition of the ectomycorrhizal (EMC) fungal communities of sand pine (Pinus clausa var. immuginata). Root tips were sampled from four trees located within Eglin Air Force Base. Colonization was shown to differ significantly based on tree identity. Abundance, species diversity, and the ratio of ECM fungi to pathogenic fungi did not differ significantly based on tree identity. A total of 35 ECM operational taxonomic units (OTUs) were shown to colonize the four trees. Helotiales4, Lactarius2, and Cenococcum geophilum were found to be the most abundant OTUs, while Lactarius1 was …
