The Effects Of Environmental Enrichment On Abstinence And Relapse Using An Animal Conflict Model, Joshua Alan Peck

Dissertations, Theses, and Capstone Projects

Heroin addiction is a significant health and societal problem for which there is no effective and well-accepted long-term behavioral or pharmacological treatment. Therefore, strategies that prolong heroin abstinence should be the primary focus of heroin treatment research. There is promising evidence that environmental enrichment may indeed support drug abstinence in animals using the reinstatement model of abstinence and relapse. The current studies used an animal conflict model that captures the aversive consequences of drug seeking (as are typical in humans, e.g., arrest, incarceration, job loss, and strained social relationships) to test the effects of environmental enrichment on heroin abstinence, prolonged …

Occupy Wall Street's Challenge To An American Public Transcript, Christopher Neville Leary

Dissertations, Theses, and Capstone Projects

This dissertation examines the rhetoric and discourses of the anti-corporate movement Occupy Wall Street, using frameworks from political ethnography and critical discourse analysis to offer a thick, triangulated description of a single event, Occupy Wall Street's occupation of Zuccotti Park. The study shows how Occupy achieved a disturbing positionality relative to the forces which routinely dominate public discourse and proposes that Occupy's encampment was politically intolerable to the status quo because the movement held the potential to consolidate critical thought and action. Because the "soft" means of re-capturing public consent were weak in 2011 because of the 2008 economic collapse, …

The Development And Function Of The Nasopharynx And Its Role In The Evolution Of Primate Respiratory Abilities, Anthony Santino Pagano

Dissertations, Theses, and Capstone Projects

The nasopharynx is a centrally located region of the upper respiratory tract (URT) integral to several physiological functions. However, few have focused on this area within the context of human evolution. This study investigated osseous morphology, soft tissue histology, development, and evolutionary change of the nasopharynx. Multimodal analyses were performed:

Analysis 1: This study tested hypotheses on the morphological relationships of the osseous nasopharyngeal boundaries with the splanchnocranium and basicranium among dry crania representing humans and non-human primates using 3D geometric morphometrics (3D-GM). Results showed that humans, the most orthognathic group, exhibited the widest nasopharynges. Over human development, the nasopharynx …

A Feminist Inheritance? Questions Of Subjectivity And Ambivalence In Paul Mccarthy, Mike Kelley And Robert Gober, Marisa White-Hartman

Dissertations, Theses, and Capstone Projects

Feminist art of the 1970s was groundbreaking in many regards and importantly impacted specific projects by three male artists: Paul McCarthy's performance Sailor's Meat (1975), Mike Kelley's installation Half a Man (1989) and Robert Gober's 1989 installation at the Paula Cooper Gallery. Despite the general absence of feminist artists as possible influences in the critical literature on these artists, feminist sources have been hidden in plain sight in regards to these works. These artists all take up the problematic of identity formation within the domestic sphere, which was made a legitimate area of inquiry in art by numerous feminist artists …

Attention Shapes Our Expectations And Perceptions: The Neural Mechanisms Of Top-Down Attention During Adulthood And Development, Snigdha Banerjee

Dissertations, Theses, and Capstone Projects

Top-down attention is the focusing of attention at one's will through knowledge regarding a current task. There is evidence that top-down attention involves the modulation of sensory cortices by higher order regions. However, the mechanisms of top-down attention across sensory modalities, its influence on early sensory inputs, as well as interactions with motivational systems remain unclear. We performed the following set of electrophysiological experiments in typically developed adults and adolescents to examine these areas. 1) The supramodal attentional theory holds that parietally-based attentional mechanisms are shared across sensory modalities. We tested the supramodal theory by examining if lateralized parieto-occipital alpha-band …

Works In Progress: Child Characters In Victorian And Postcolonial Fiction, 1814 - 2006, Kiran Mascarenhas

Dissertations, Theses, and Capstone Projects

In this dissertation I analyze the relationship between national and individual development in Victorian and postcolonial novels set in India. My central argument is that the investment in the idea of progress that characterizes colonial narratives of childhood gives way in postcolonial fiction to a suspicion of dominant understandings of progress, and that this difference is manifest in the identity formation of the child character as well as in the form of the novel.

In the Victorian colonial narratives discussed in this study, the bildung of the child involves the overcoming of the child's conflicted cultural identity. The children of …

The Interaction Between Arsenic And Struvite During Coprecipitation And Adsorption Processes, Ning Ma

Dissertations, Theses, and Capstone Projects

The formation of struvite, MgNH4PO4*6H2O (MAP), from wastes is one of the methods that can be used to recover P from wastes efficiently. However, since there are usually toxic components in the wastes, like arsenic (As), the possibility of having toxic contaminants in MAP is a big concern. So, the interaction between As and MAP during coprecipitation (CPT) and adsorption (ADS) processes were studied at pH 8-11. MAP precipitated without As at pH 8-11 was also characterized.

During CPT process, the MAP was precipitated from a MgCl2-(NH4)2HPO4-NaCl-H2O system spiked with As at an initial pH (pHi) of 8-11. The batch …

Executive Dysfunction And Reward Dysregulation: Interactions In Drug Addiction, Kristen Paula Morie

Dissertations, Theses, and Capstone Projects

Cocaine addiction is a serious public health hazard, and contributes to disastrous outcomes for individuals who suffer from it. Addiction is accompanied by an inability to control one's own behavior, and a preoccupation with cocaine at the expense of other rewarding pursuits. Previous research has suggested that difficulties with executive function and reward processing may underlie these problems, but the extent to which each contributes to addiction severity, or how these two factors may interact, remains to be elucidated. By using event related potential (ERP) measures in combination with information about self-reported anhedonia over three experiments, we set out to …

Dynamics And Divisions At The Salons Of The Rose-Croix: Statistics, Aesthetic Theories, Practices, And Subjects, Mary Slavkin

Dissertations, Theses, and Capstone Projects

A variety of alternative Salons arose in France following the demise of the official Salon. Within this phrenetic climate for alternative exhibition venue creation, Joséphin Péladan founded the Salons of the Rose + Croix (1892-1897). He framed the Salons as ideologically unified exhibitions at which idealized works focusing on spirituality, tradition, and beauty would engender social reform by encouraging a decadent society to focus on timeless poetic and mystical ideas. Nevertheless, in practice the Rose + Croix functioned mainly as an exhibition venue for artists whose work only loosely responded to the established platform. The exhibited works reveal some overlap …

Fabrication And Characterization Of Sol-Gel Based Nanoparticles For Drug Delivery, Reeta Yadav

Dissertations, Theses, and Capstone Projects

Nanogels are cross linked polymeric sol-gel based nanoparticles that offer an interior network for incorporation and protection of biomolecules, exhibiting unique advantages for polymer based delivery systems. We have successfully synthesized stable sol-gel nanoparticles by means of [a] silicification reactions using cationic peptides like polylysine as gelating agents, and [b] lyophilization of sol-gels. Macromolecules such as Hemoglobin and Glucose Oxidase and small molecules such as Sodium Nitroprusside (SNP) and antibiotics were encapsulated within the nanogels. We have used transmission electron microscopy, dynamic light scattering, zeta potential analysis, and spectroscopy to perform a physicochemical characterization of the nanogels resulting from the …

Effects Of Low Velocity Impact On The Flexural Strength Of Composite Sandwich Structures, Jeffrey Scott Carter

Master's Theses

The use of composite sandwich structures is rapidly increasing in the aerospace industry because of their increased strength-to-weight and stiffness-to-weight characteristics. The effects of low velocity impacts on these structures, however, are the main weakness that hinders further use of them in the industry because the damages from these loadings can often be catastrophic. Impact behavior of composite materials in general is a crucial consideration for a designer but can be difficult to describe theoretically. Because of this, experimental analysis is typically used to attempt to describe the behavior of composite sandwiches under impact loads. Experimental testing can still be …

Comparison Of Coral Reef Health: Lokobe National Park And Tanikely National Park, Northwest Madagascar, Kailani Acosta

Independent Study Project (ISP) Collection

Coral reefs are microcosms of biodiversity and life. They are home to about a quarter of all marine life, yet amount to only about 1% of the world’s marine environment. Coral reefs are very vulnerable ecosystems; there are numerous threats to their health, such as damage by echinoderm and fish feeding, natural disasters, coral illness and bleaching events. Coral health fluctuates according to many of these factors and as a result of the fragile symbiotic balance between zooxanthellae algae and corals. Subsequently, coral health is an essential topic for analysis and assessment.

Coral reefs were assessed in Lokobe National Park, …

The Ecology Of Infancy And Early Childhood In Rural Senegal; A Five Year Old Can Boot But Not Foot, An Exploration Of Where Biology Meets Culture, Heather Mills

Independent Study Project (ISP) Collection

This research project explores the life stages of infancy and early childhood in the village of Ndiane in the Thies region of Senegal. I will discuss how biology meets culture to influence children, parenting styles, and expectations of the life stage. How does ecology, the interaction of physical, biological and cultural landscapes, characterize childhood and the intertwined belief systems that influence parenting? The information was gathered using a combination of participant observation and free list interviews.

“I Pray You Enough”: Exploring Rural Early Childhood Development Through The Narratives Of Caregivers., Bethany G. Hart

Independent Study Project (ISP) Collection

Childhood, including the antenatal period, is a time of invaluable physical and mental development – the effects of which last a lifetime. These experiences are shaped by a host of external factors (such as nutrition or mental stimulation) that are heavily affected by socioeconomic status. A study by the United Nations International Childrens Emergency Fund (UNICEF) found that South African children in rural areas are more physically and cognitively delayed than their less-rural peers (2007). Thus, the purpose of this study was to gain insight into the rearing and development of young children (5 years and under) in a rural …

Who Are You Wearing? A Study Of Moroccan Fashion Discourse, Identity Performance, And Social Change, Leah Michalove

Independent Study Project (ISP) Collection

Clothes and their consumption become almost invisible in their very ubiquity, yet fashion acts as a sort of optical litmus test for the mood of society. Clothing can express cultural norms, serve as shorthand for social grouping, and provide a kind of corpus of visual allusion; in short, clothes and how we wear them constitute a system of signification, a visual language as dynamic, complex, and arbitrary as any spoken communication. I set out to investigate the grammar and syntax of Moroccan fashion, to explore what the diversity of observed choices meant to the people who made them and how …

Cabelo Crespo: A Struggle For Inclusion In Brazilian Society, Ashley Hamilton

Independent Study Project (ISP) Collection

Present-day Brazilian society presents a disproportionate number of economic, social and political challenges for Black women. The phenomenon of this structural inequality has causes that are rooted deep in the history of Brazil, and is built upon the foundation lain by slavery, resulting in the economic prosperity of the elite that was built upon the foundation of the labor provided by people of color. The effects of colonization and the profitable slave trade that ensued continue to contribute still, to the plight of people of color in general, though the focus of this project will be on the effects these …

The Effects Of Cannabidiol On The Electrical And Contractile Properties Of Cardiomyocytes, Ramez Ali Mansour

Theses

In earlier studies, cannabidiol (CBD), a major nonpsychotropic cannabinoid found in cannabis plant, has been shown to influence cardiovascular functions under various physiological and pathological conditions. In the present study, the effects of CBD on contractility and electrical properties of rat ventricular myocytes were investigated. Video edge detection was used to measure myocyte shortening. Intracellular Ca2+ was measured in cells loaded with the fluorescent indicator fura-2 AM. CBD (1 μM) caused a significant decrease in the amplitudes of electrically-evoked myocyte shortening and Ca2+ transients. However, the amplitudes of caffeine-evoked Ca2+ transients and the rate of recovery of electrically-evoked Ca2+ transients …

Epigenetics And Social Context: Implications For Disparity In Cardiovascular Disease, Karen L. Saban, Herbert L. Matthews, Holli A. Devon, Linda W. Janusek

Nursing: School of Nursing Faculty Publications and Other Works

BACKGROUND:

Although it is well established that African Americans (AA) experience greater social stressors than non-Hispanic Whites (NHW), the extent to which early life adversity and cumulative social stressors such as perceived discrimination, neighborhood violence, subjective social status, and socioeconomic status contribute to disparity in coronary heart disease (CHD) and stroke between AA and NHW are not well understood.

PURPOSE:

The purpose of this paper is to propose a conceptual model based upon McEwen’s Allostatic Load Model suggesting how the relationships among social context, early life adversity, psychological stress, inflammation, adaptation, and epigenetic signature may contribute to the development of …

Antelope Valley is situated in Southern California and is bounded by the Tehachapi and the San Gabriel Mountains. It stretches over 2,200 mi2 and encompasses Rosamond Dry Lake and the 1,200 mi2 watershed draining into it. The cities of Lancaster and Palmdale are the two major urban centers that lie in the watershed draining into Rosamond Dry Lake. The lake lies within the vicinity of the Edwards Air Force Base and provides an important site for aviation research and test operations in addition to ecosystem services. Hence, it is necessary to balance the need to remove water from the lake …

Sacred Cows, Holy Wars: Exploring The Limits Of Law In The Regulation Of Raw Milk And Kosher Meat, Kenneth Lasson

All Faculty Scholarship

In a free society law and religion seldom coincide comfortably, tending instead to reflect the inherent tension that often resides between the two. This is nowhere more apparent than in America, where the underlying principle upon which the first freedom enunciated by the Constitution's Bill of Rights is based ‒ the separation of church and state – is conceptually at odds with the pragmatic compromises that may be reached. But our adherence to the primacy of individual rights and civil liberties ‒ that any activity must be permitted if it is not imposed upon others without their consent, and if …
