Les Représentations Féminins Dans Le Cinéma Maghrébin: L'Expérience Des Femmes Et Le Rêve Féministe Dans Les Silences Du Palais Et Viva Laldjérie, Danielle Mills

Theses and Dissertations--Modern and Classical Languages, Literature and Cultures

It is evident that in the realm of gender studies concerning the Maghreb, many scholars have studied literary texts from prominent female Maghrebi writers such as Assia Djebar and Fatima Mernissi. However, certain forms of expression have been neglected, such as film. The purpose of this work is to analyze and evaluate how cinema has portrayed the situation of women in the postcolonial Maghreb. I will be examining two examples of Maghrebi cinema which include the Tunisian film Les silences du palais by Moufida Tlatli and the Algerian film Viva Laldjérie by Nadir Moknèche. Through the examination of these two …

Metabolic Diversity Among Fibroblasts From Regenerating And Non-Regenerating Mammals, Ebenezer Aryee

Theses and Dissertations--Biology

Regeneration is a wound repair process that terminates in the restoration of tissue function and structure. Fibroblasts play pivotal roles in regenerative and fibrotic wound repair. Reports of extensive regenerative ability in mammals have been historically rare, but more recently spiny mice (Acomys) have emerged as a bona fide model of complex tissue regeneration. Recent work has indicated that fibroblasts from regenerators (Acomys and Oryctolagus) are more resistant to reactive oxygen species (ROS)-induced senescence compared to non-regenerating species, suggesting the influence of intrinsic cellular states on the fate of wound repair. Determining the basal metabolic signature …

Tryptophan-Like Fluorescence And Non-Point Source Pollution In Karst Basins, Inner Bluegrass Region, Kentucky, Ryan Dapkus

Theses and Dissertations--Earth and Environmental Sciences

Typically, the degree of fecal contamination of water is assessed by the concentration of thermotolerant coliforms, like E. coli. This method is time-consuming, taking > 18 hours between the start of incubation and subsequent enumeration. The current study examines the utility of monitoring tryptophan-like fluorescence (TLF) using in-situ fluorometers as a proxy for fecal contamination, particularly E. coli. Relative timing of discharge peaks and TLF peaks is considered, as well as differences in E. coli concentrations and major anion concentrations between two different basins that were monitored weekly. Results indicate that TLF is somewhat useful in the prediction of …

Drawing on 16 months of ethnographic fieldwork, which included semi-structured interviews and participant observation alongside historical archival investigation, this dissertation examines the following questions: What international organizations, national government, and private sector policies govern remittances? How does Indigenous collective work and communal governance shape remittance management? How do the responsibilities of family members shift with migration and how …

Undoing Colorblind Ecologies: Redlining And Just Green Enough In The Urban Forest Of Boston's Franklin Park, Chelsea M. Parise

Theses and Dissertations--Geography

Urban political ecology research increasingly engages multi-disciplinary methodologies to clarify the role that the botanic plays in creating, maintaining, or subverting ecological geographies of power. Fredrick Law Olmsted intended the forest within Franklin Park to heal the physical degeneration and social disunity he believed resulted from urban living conditions but instead the forest within Franklin Park has grown in contexts of increasingly complex environmental and racial difference. I examine how the urban forest in Boston’s Franklin Park has ecologically manifested racialized power relations through distinct periods of elite nature-making and segregated grassroots stewardship. I utilized archival research, forest surveys, and …

This archival research examines the transformation of its horseracing and housing geographies during the 1930s by comparing the redevelopment of an old urban racetrack into federal public housing with the simultaneous development of a new racing plant in the nearby countryside. It analyzes the social and economic relations underlying this shift in addition to how these relations were naturalized by the new landscapes they created. Results suggest that a local growth coalition was seeking to emerge from a financial crisis through a spatial fix that capitalized on cultural …

Elephants In The Room: Covid-19 Pandemic Political Ecologies Of Tourism In Tanzania, Helen C. Richardson

Theses and Dissertations--Geography

The COVID-19 pandemic brought forth unprecedented and ever-changing crisis and disruption to societies and economies around the globe.[1] As the COVID-19 pandemic continues to interrupt travel worldwide, the tourism industry, and the countries who rely on it as a major source of income, are in crisis. These processes have reconfigured economic capital flows and foreign investment in the global south. This is particularly the case in Tanzania, as tourism was Tanzania’s highest foreign exchange earner and accounted for 17% of Tanzania’s gross domestic product in 2019.[2] This project draws upon a political ecology framework to examine the Tanzanian …

Fighting 'Stance': The Role Of Conversational Positioning In League Of Legends (Multiplayer Online Battle Arena) Discourse, William Breslove

Theses and Dissertations--Linguistics

For researchers, the study of video game players - how they behave, interact, and cooperate in a virtual world – presents a challenge: what methodologies are best suited to approaching these interactions? From a sociolinguistic approach, how do gamers converse, and what do these conversations reveal about epistemic, affective, and political relationships? This study uses John DuBois’ Stance Theory (2007) and recent modifications of it (Kiesling 2022), to analyze data gathered from the popular multiplayer online battle-arena (MOBA) game League of Legends. It focuses on in-game interlocutors’ conversation samples to show their positioning, intersubjective alignment, and evaluation of a …

La Representación De La Masculinidad En El Personaje Del Policía: Cine, Televisión Y Novela Española Del Siglo Xxi, Daniel Fonfría-Perera

Theses and Dissertations--Hispanic Studies

This research focuses on the type of hegemonic masculinity—a term that has traditionally belonged to a purely sociology domain—exhorted in the works of fiction published and released in Spain in the last two decades, searching for patterns that indicate that a normative type is encouraged. After tracing the different types of hegemonic masculinities that have characterized policemen since the late 30’s, the findings show how the modern notion of masculinity depicted in the works analyzed, even though it can no longer be considered monolithic, still shares some patterns with the masculinity predominant in cultural products during Francoism.

The thriving elements of spiritual influence, personal competence, peer support, and family cohesion were surveyed and analyzed using a resiliency lens. Findings include gay male agricultural educators thriving in a heteronormative profession. Recommendations include ensuring LGBTQIA+ teachers have a voice in agricultural education.

Out Of Sight, Out Of Mind: An Evaluation Of Secondary Agricultural Textbooks, Tara Elizabeth Rojas

Theses and Dissertations--Community & Leadership Development

Students are impacted by representation present within their lives in the media they consume, organizations in which they participate, and school interactions. Among school interactions with primarily White school staff, students interact with textbooks to learn about industry norms and concepts. Missing representation can harm students’ sense of belonging which can lead to feelings like solo-status or isolation. Using both critical race theory and social semiotics, this work explores the representation present within secondary agricultural textbooks. The first study utilizes photos and case studies, observing both gender and race as mutually exclusive variables and compares data to the current public-school …

Investigating The Effects Of In-Vivo Therapeutics Hypoxia Treatment Paradigms In Neurite Outgrowth Patterns, Jae Hyun Yoo

Theses and Dissertations--Medical Sciences

Spinal cord injury, specifically in the cervical C3-C4 region of the cervical spine, contributes to impaired breathing and a diminished quality of life. Therefore it is important to find effective and safe therapeutics to restore breathing function. Indeed, there are a myriad of research being performed in addition to valuable collaboration amongst different institutions. As such, inspired by a previous experiment, we decided to test our hypothesis that an enriching environment consisting of different hypoxic environments - sustained and intermittent hypoxia alongside normoxia - would result in neurite outgrowth. Moreover, we hypothesized that sustained hypoxia would result in the greatest …

Evaluating The Role Of Mmp9 In Hyperhomocysteinemia Induced Cerebrovascular Pathology, Alexandria Linton

Theses and Dissertations--Neuroscience

Vascular contributions to cognitive impairment and dementia (VCID) is one of the leading causes of dementia, along with Alzheimer’s disease (AD), and often manifests as a comorbidity of AD. Elevated plasma homocysteine, known as hyperhomocysteinemia (HHcy), is a risk factor for VCID; however, the mechanism underlying the connection between HHcy and development of VCID pathology remains elusive. Understanding this mechanism would reveal novel therapeutic targets with the potential to be disease modifying, which are a critical need for a disease that lacks any approved treatment. Previous studies from our lab have strongly associated neuroinflammation and blood brain barrier (BBB) dysregulation …

Parental Barriers Toward Seeking Mental Healthcare For Saudi Children At Risk Of Adhd, Amani Kappi

Theses and Dissertations--Nursing

Attention deficit hyperactivity disorder (ADHD) is a mental health disorder commonly diagnosed in childhood. Underdiagnosis and undertreatment of ADHD can lead to the development of other mental illnesses and disruptions in social functioning in adulthood. Therefore, parents can play a crucial role in proactively seeking mental healthcare for children who are at risk for or who have a clear diagnosis of ADHD. Studies in the United Kingdom and the United States highlight many barriers that prevent parents from seeking mental healthcare for their children, such as negative attitudes towards the mental healthcare system and stigma towards mental illnesses.

Advanced gastrointestinal endoscopy includes a group of specialized procedures and interventions that are being performed more frequently with little attention given to a patient’s preprocedural anxiety issues. Preprocedural anxiety is an anticipated problem with any surgery or invasive procedure and if sustained or experienced excessively, is associated with negative clinical factors and complications.

In the beginning of 2020, the United States was met with a global pandemic caused by the coronavirus SARS-CoV-2, termed COVID-19. There were recommendations to decrease medical procedural case volume in order to slow the spread of the virus, protect staff and patients from getting the virus, …

Building Tools For Improved Modulation Of The Human Gabaa Receptor, A Central Nervous System Target For The Treatment Of Anxiety, Garrett Edward Zinck

Theses and Dissertations--Pharmacy

In the U.S., anxiety is recognized as an increasing range of mentally and physically debilitating psychiatric health disorders with significant economic repercussions. Over the last 20 years, several novel anti-anxiety therapies have entered the drug development pipeline, but none have made it to market.

The work in this dissertation focused on structurally modifying valerenic acid (VA), a structurally unique carboxylated sesquiterpene acid found in Valeriana officinalis. VA is putatively reported to have allosteric modulatory activity of the human GABA_A receptor, a ligand-gated ion channel responsible for attenuating neurotransmissions. Structural modeling of VA’s GABA_A receptor interaction suggests that …

Analysis Of Potential Facilitators To Use Of Hiv Pre-Exposure Prophylaxis (Prep) In A Young Transgender Population, Noah Dixon

Theses and Dissertations--Pharmacy

Pre-exposure prophylaxis for HIV prevention (PrEP) is heavily under-utilized in transgender youth, a population which experiences high risk factors for contracting HIV and exhibits unique barriers to care. This retrospective study used a secondary data analysis of survey results from transgender youth between 16-and 24-years-old to analyze various exposures for association with PrEP use. It was hypothesized that medical gender affirming therapy, mental health care treatment, and HIV programming would be independently associated with increased use of PrEP in transgender youth. It was found that only HIV prevention services and programming related to HIV or gender identity were associated with …

Investigating The Physical Stability Of Amorphous Pharmaceutical Formulations, Travis W. Jarrells

Theses and Dissertations--Pharmacy

Amorphous formulations, including amorphous solid dispersions (ASDs), consisting of the active pharmaceutical ingredient (API) intimately mixed in a polymeric matrix, are an attractive formulation approach to improve drug delivery, dissolution, and solubility. However, an amorphous API in an ASD is in a higher energy state compared to the crystalline drug and results in most ASDs being inherently unstable. The polymer helps to stabilize the amorphous drug against crystallization such that the resulting homogenous mixture maintains its solubility advantage relative to the crystalline form. One challenge of ASDs is that the presence of impurities including crystals or residual solvent, variations in …

In-Situ Characterization Of Burr Formation In Finish Machining Of Inconel 718, Hamzah M. Zannoun

Theses and Dissertations--Mechanical and Aerospace Engineering

One of the undesirable byproducts that occur during the machining process is the development of burrs, which are defined as rough excess material that forms around the geometric discontinuities of a part. Burrs are especially problematic because they have negative impacts across the triple bottom line: economic, environmental, societal. For one, they are expensive to remove because the deburring process is entirely manual and requires skill. Further, burr material is typically discarded which is adding to the already mounting waste generated from machining such as in coolant and chip disposal. Lastly, there are many societal implications, such as operator injury …
