Self-Objectification And Self-Surveillance In African American And Latina Girls: Links To Body Dissatisfaction And Self-Worth, Kimberly A. Burdette
Self-Objectification And Self-Surveillance In African American And Latina Girls: Links To Body Dissatisfaction And Self-Worth, Kimberly A. Burdette
Master's Theses
Drawing on a sample of low-income African American and Latina girls, the goal of the present investigation was to examine the relevance of self-objectification and self-surveillance to body dissatisfaction and self-worth. Body mass index (BMI), ethnicity, and perceived athletic competence were examined as moderators of these relations. Participants were 10- to 14-year-old African American and Latina girls recruited from a summer camp targeting low-income, urban girls. Surveys that include measures of self-objectification, self-surveillance, body dissatisfaction, self-worth, and perceived athletic competence were individually administered to participants by a research assistant. Height and weight were measured to calculate BMI. Ethnicity information was …
Chicago Housing: Understanding How Local Organizations Mobilize To Preserve Public And Affordable Housing, Cameron Williams
Chicago Housing: Understanding How Local Organizations Mobilize To Preserve Public And Affordable Housing, Cameron Williams
Master's Theses
Under the Plan for Transformation section 8 voucher use and mixed-income developments have increased in Chicago. Several developments have been demolished and replaced with mixed-income developments that are argued to provide better conditions and opportunities for public housing residents, but empirically have mixed results. Lathrop Homes is a public housing development that has withstood the mass demolitions and efforts to make it mixed-income because of resident and organizer challenges to the Chicago Housing Authority. Resident and organizer input for this study reveals their strong stance against the mixed-income development Lathrop Homes could become. The interests behind opposition might diverge, but …
Examination Of Multiparticle Transport As A Function Of Slope And Sediment Volume, Alan Kuoch
Examination Of Multiparticle Transport As A Function Of Slope And Sediment Volume, Alan Kuoch
Master's Theses
Recent studies of sediment transport have shifted from the traditional continuum paradigm to a particle-based approach. A previous dry ravel flume experiment on single particle transport showed that the angle of repose represented a shift between friction-controlled gentle slopes dominated by local transport and inertia-driven steep slopes dominated by nonlocal transport. My flume study explored multiparticle transport and the effect of sediment volume on transport distance. The flume experiments revealed a negative relationship between sediment volume and transport distance. As sediment volume increased, inter-particle collisions increased, which led to particle jamming and a reduction in transport distance. Furthermore, a higher …
Between, Patricia Valeria Pinedo
Between, Patricia Valeria Pinedo
Master's Theses
This thesis is a collection of poetry based on the farm worker Grape Boycott of 1965-1970. Through personal narrative and formal poetic techniques, the collection presents a migrant family struggling to understand where it belongs in choosing between joining the boycott or not. The Mexican-American family is depicted in relation to struggles of the time, thus emphasizing the historical situation. The collection asks each reader what side of the Grape Boycott he or she would have joined. The poems shed light on the internal struggle of those who both joined and did not join the boycott.
Effects Of Mlc Gene Modulation On Acetate Accumulation In Escherichia Coli Culture, Melvin Chen
Effects Of Mlc Gene Modulation On Acetate Accumulation In Escherichia Coli Culture, Melvin Chen
Master's Theses
When Escherichia coli (E. coli) is grown in the presence of excess glucose, acetate is produced, oftentimes as an undesired by-product. Mlc is a global repressor for sugar transporters in E. coli, including glucose. This body of work examines the overexpression of Mlc via expression vectors in E. coli cultures under constitutive and inducible promoters. Sequence changes to the translational start codon and codon 52 of the mlc sequence inserted in the expression vectors were introduced. These changes were evaluated for their impact on glucose uptake rates, acetate production, and overall cell growth when Mlc was overexpressed in E. coli …
Synthesis Of Hybrid Inositol Glycan Analogues, Sudi Sabet
Synthesis Of Hybrid Inositol Glycan Analogues, Sudi Sabet
Master's Theses
A 2010 study by Centers for Disease Control and Prevention has projected that one of three US adults could have diabetes by the year 2050. More than 90% of the diagnosed cases are Type II diabetes, a condition characterized by insulin resistance. In search of new antidiabetic drugs, a class of natural, phosphorylated, inositol-containing pseudosaccharides called inositol glycans (IGs) has been studied for years. These compounds have insulin-mimetic activity in insulin-sensitive cells and can stimulate processes such as lipogenesis and glucose transport. Due to the heterogeneity of IGs, it is very difficult to isolate them from their natural sources, and …
Plankton In Monterey Bay: Optimization Of Optical Sensor Data From Autonomous Underwater Vehicles With Applications In Plankton Community Composition, Diane Wyse
Master's Theses
Autonomous underwater vehicles (AUVs) equipped with oceanographic sensors demonstrate the capability to describe plankton communities in the marine environment. The vehicles collect data from the surface through the mixed layer for a variety of oceanographic parameters. The Monterey Bay Aquarium Research Institute operates the Dorado upper-water-column AUV. The Dorado AUV collects data for 32 size-classes, from 1.25 to 250 μm, using a laser in-situ scattering and transmissometry (LISST-100X) instrument. The objective of this study is to analyze data from AUVs and laboratory work to inform sampling methods with applications in targeting specific classes of plankton, particularly harmful algal bloom species. …
Pathway To The Podium: Situating Rhetorical Agency Within The Tommie Smith And John Carlos 1968 Mexico City Olympic Protest, Andrew Carter
Pathway To The Podium: Situating Rhetorical Agency Within The Tommie Smith And John Carlos 1968 Mexico City Olympic Protest, Andrew Carter
Master's Theses
The recent romanticization and celebration of the Tommie Smith and John Carlos 1968 Mexico City Olympic Protest has allowed contemporary American society to recognize both athletes as heroes and pioneers within the Civil Rights movement. They have been honored with of a number of awards both nationally and internationally, as well as memorialized with a 22-foot high statue that was erected on the campus of San José State University in 2005. From once being ostracized as national villains, Smith and Carlos have come full circle in how they are referenced within public consciousness. However this recent transformation on the part …
Networking And Craft In Three Generations Of Mail Art, Laura Dunkin-Hubby
Networking And Craft In Three Generations Of Mail Art, Laura Dunkin-Hubby
Master's Theses
This thesis examines two threads in the history of mail art: a networking approach dedicated to open participation and a crafted approach dedicated to the art object. It then follows these two threads across three generations. Mail art is an international phenomenon that evolved over the past sixty odd years due to the efforts of a dedicated and growing group of individuals. American artist Ray Johnson and the international artistic group operating under the banner of Fluxus are discussed as establishing mail art as a separate form through their creation of the mail art network. The generation that followed Johnson …
The Work Engagement And Job Performance Relationship: Exploring The Mediating Effect Of Trait Emotional Intelligence, Lisa Jackson
The Work Engagement And Job Performance Relationship: Exploring The Mediating Effect Of Trait Emotional Intelligence, Lisa Jackson
Master's Theses
This cross-sectional study examined the mediating effect of affect-related traits on the relationship between work engagement and job performance. Specifically, a sample of 225 students from a large state university was used to examine the effect of trait emotional intelligence (EI) on work engagement and both in-role and extra-role performance. It was found that work engagement directly impacted both in-role and extra-role performance, indicating that engaged workers are more likely to perform well both on job-related tasks (in-role performance) and also on going above and beyond what was expected of them in their job role (extra-role performance). In addition, work …
Vulnerability Of Groundwater To Perchloroethylene Contamination From Dry Cleaners In The Niles Cone Groundwater Basin, Southern Alameda County, California, Anne C. Jurek
Master's Theses
Releases of perchloroethylene (PCE) from dry cleaners pose a threat to groundwater quality. An assessment was performed of the Niles Cone Groundwater Basin to determine its vulnerability to PCE contamination from both historic and more recently operating dry cleaners. Sensitivity assessments of the Basin's two subbasins were performed using a modification of the DRASTIC Index Method, whereby the hydrogeological variables of depth to water, aquifer media, vadose zone media, and soil drainage classification were represented by a range of sensitivity categories and ratings assigned to each range. A source assessment was performed by identifying the locations of historic and presently …
Hip-Hop, Medellín And Social Change, Veronica Henao Posada
Hip-Hop, Medellín And Social Change, Veronica Henao Posada
Master's Theses
This study explores the ways in which the Hip-hop movement is producing social change in Medellín, Colombia. Looking specifically at a Hip-hop school called Cuatro Elementos Skuela, which exists autonomously and with very little state support in the Medellín neighborhood of Aranjuez, I argue that young people are contributing to the reconstruction of the city’s social, cultural and economic fabric. I start by explaining the historical context of Medellín, describing the different sets of conflicts that unleashed high levels of violence and caused the fragmentation of the social, cultural and economic fabric. Moreover, I review the role of the …

Effects Of Increasing Temperature And Ocean Acidification On The Microstages Of Two Populations Of Saccharina Latissima In The Northwest Atlantic, Sarah Redmond
Master's Theses
Saccharina latissima (Linnaeus) C.E.Lane, C.Mayes, L.D. Druehl and G.W.Saunders, is the most widely distributed species of kelp in the western North Atlantic, occurring from the Arctic to Long Island Sound. The effects of global climate change on these ecologically and economically important cold temperate species at the southern range of their distribution are unknown. This study investigated the impact of the combined stressors of increased temperature (16, 19, 22, 25 & 28°C) and reduced pH (7.9, 7.8, 7.7, & 7.6) on the gametophyte and juvenile sporophyte stages of sugar kelp populations from Maine and Long Island Sound. Spore germination and …
The Lion & The Ringmaster: Croatia's Accession To The European Union, Jelena N. Bilandzich
The Lion & The Ringmaster: Croatia's Accession To The European Union, Jelena N. Bilandzich
Master's Theses
July 1, 2013 marked Croatia's official induction into the European Union. For Croatia this was the culmination of a long negotiation process filled with concessions and challenges. This situation inspired the question of how Croatia's alliance with the EU has affected the state? In order to analyze this relationship the aspects of Croatian identity and sovereignty were explored, in addition to the EU's principles and problems regarding member and candidate states. The evidence found within this investigation came from a number of literary sources ranging from the academic to official government documents. Furthermore, nine interviews were conducted within Croatia, which …
Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca
Land Grabs And Implications On Food Sovereignty And Social Justice In Senegal, Joanna Lafrancesca
Master's Theses
This thesis focuses on the case study of Senegal to examine the implications of large- scale land acquisitions on the livelihoods of small-scale farmers. I investigate the diverse perspectives of market enthusiasts, human rights organizations, peasants, the state, and international financial organizations on large-scale land acquisitions. Based on primary research, I argue that the state of Senegal plays an active role in permitting “land grabs” and that they pose a threat to food sovereignty among Senegalese host communities. Lastly, I argue there needs to be a broader understanding of long-term consequences and risks to insure social justice in areas affected …
Between Mobility And Stability: Immigration, Free Trade, And Human Rights In The Context Of The Latino Immigrant, Joseph M. Stosberg
Between Mobility And Stability: Immigration, Free Trade, And Human Rights In The Context Of The Latino Immigrant, Joseph M. Stosberg
Master's Theses
This work takes a multi-dimensional approach to understanding human rights abuse toward Latino immigrants. It is argued here that the opening up of Mexico and Central American countries to free trade, and the restricted movement across borders has increased human rights abuse toward immigrants. In order to investigate these issues this research looks at: the opening up of Mexico and Central American countries to free trade; a pervasive narrative that portrays the Latino immigrant as a threat; and U.S. immigration policy. I use these respective bodies of literature to guide the discussion of the Latino immigrant experience, from the decision …
The Plight Of Kenyan Domestic Workers In Gulf Countries, Caroline Muthoni Gikuru
The Plight Of Kenyan Domestic Workers In Gulf Countries, Caroline Muthoni Gikuru
Master's Theses
Kenya’s economy remains the regional leader within the East African Community (EAC) and among East African countries at large. However, political instability such as the 2007 post-election violence and the region’s social and political instability trickling into Kenya, have negatively affected the country’s economic growth. To bridge the economic gap, Kenyan women are seeking employment in the domestic service sector in the Gulf Countries, with Saudi Arabia being the most popular destination. At their destination countries, some domestic workers are subjected to various forms of abuse by their employers, leaving the worker without recourse due to the lack of legal …
From Corps To Co-Ops: Are Co-Operatives A Viable Reintegration Strategy For Ex-Combatants?, Patrick Moses Musibi
From Corps To Co-Ops: Are Co-Operatives A Viable Reintegration Strategy For Ex-Combatants?, Patrick Moses Musibi
Master's Theses
From 1989, Disarmament, Demobilization and Reintegration (DDR) programmes have played a major role in peace agreements worldwide. The first United Nations peacekeeping mission with a DDR mandate was ONUCA, (Observadores de las Naciones Unidas en Centroamerica) or the United Nations Observer Group in Central America and involved the reintegration of ex-combatants after the conflict had finished. While the disarmament and demobilization phases of the DDR programs are fairly straightforward events, success in the reintegration phase remains a great challenge. In this thesis I argue that paying closer attention to the challenges facing ex-combatants at an individual level can help in …

Master's Theses
Cameroon, one of the countries in the world that continues to criminalize homosexuality, has been on the news recently due to the torture and murder of young journalist and gay activist, Eric Ohena. This paper examines the discrimination faced by the LGBTI community in Cameroon by exploring the origins of homophobic violence, the role played by Cameroon's legal system, and the struggles of LGBTI Cameroonians in their fight for a better life. The analysis includes a review of the work by scholars on colonialism and sexuality in Africa, and questions the roots of violence and abuse against the LGBTI community …
The Role Of Information And Communication Technology In The Acculturation Of Vietnamese Refugees, Khanh A. Tran
The Role Of Information And Communication Technology In The Acculturation Of Vietnamese Refugees, Khanh A. Tran
Master's Theses
One of the most significant refugee populations in the United States is the Vietnamese. This group initially fled their native country to escape political oppression at the conclusion of the Vietnam War in 1975 and continued to flee in a series of separate waves that continued for more than three decades. As a relatively new immigrant group in the U.S., the Vietnamese still face a variety of challenges as they try to reestablish their lives and adapt in a new cultural environment. Acculturation is a complex process that is influenced by a number of factors. Throughout history, U.S. immigration policy …
Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang
Biochemical Assay Optimization And Computational Screening Efforts To Identify Potential Luxs Inhibitors, Keeshia Q. Wang
Master's Theses
Quorum sensing (QS) is a process of coordination of bacterial gene expression in response to cell population. System two QS is regulated by the small signaling molecule autoinducer-2 (AI-2) and is implicated in the infectious behaviors of various bacterial species. AI-2 is biosynthesized from S-ribosylhomocysteine (SRH) by the enzyme LuxS and induces interspecies cell-to-cell communication. Inhibition of LuxS would therefore inhibit interspecies QS. Herein, a search for novel molecular species that will competitively bind with SRH in the LuxS binding site is performed in silico. Computational screening results are then validated in vitro using an optimized LuxS inhibition …
Pretreatment Predictors Of Weight Loss In A Comprehensive Behavioral Weight Loss Program, Erin M. Lenz
Pretreatment Predictors Of Weight Loss In A Comprehensive Behavioral Weight Loss Program, Erin M. Lenz
Master's Theses
There is considerable variability in response to behavioral weight control treatment. Identifying pretreatment health behaviors that predict an individual’s weight loss success has the potential to assist with assignment into more appropriate treatment settings (i.e., standard behavioral program versus comprehensive home environment program) that are likely to yield greater weight loss outcomes over time. Participants (N= 201; 48.9 ± 10.5 years; 78.1% women) enrolled in a study comparing a standard behavioral weight loss program (BWL; n=99) to a home-environment focused weight loss program (BWL+H; n=102) completed baseline questionnaires assessing individual control variables (i.e., dietary restraint, self-weighing) and control over the …
Practice And Patient Characteristics Associated With Primary Care Physicians’ Use Of Electronic Consults With Their Patients, Timothy Kenneth Eng
Practice And Patient Characteristics Associated With Primary Care Physicians’ Use Of Electronic Consults With Their Patients, Timothy Kenneth Eng
Master's Theses
Electronic consults (e-consults) are types of communications systems used between physicians and their patients to communicate outside the medical office. While nothing can replace the traditional face-to-face interaction, e-consults can be used to help manage patient queue, share non-urgent information, and provide an alternative avenue of communication while recording electronic copies. Literature reveals that lack of a standardized reimbursement system, uncertain workloads, and perceived risks to patient confidentiality are barriers to mainstream adoption of e-consult systems. The purpose of this study is to investigate the practice and patient characteristics of the use of e-consults between primary care physicians (PCP) and …
Evidence And Implications Of Weight Clustering Among Adolescents, Jennifer C. Acker
Evidence And Implications Of Weight Clustering Among Adolescents, Jennifer C. Acker
Master's Theses
Both obesity and eating disorders (ED) are increasingly conceptualized from an ecological model of health, which emphasizes the importance of individual and contextual variables. The peer context is particularly important for understanding adolescents’ weight related attitudes and behaviors; however, specific peer processes that impact obesity and EDs are unclear. Because social comparison is common during adolescence, how teens view their body in comparison to the body size of their close friends may be influential. The purpose of this study is to examine how adolescents’ perceptions of their friends’ body sizes relate to their weight-related cognitions, behaviors, and mental health symptoms, …

Reassessment Of Biowish Activation Procedure For Denitrification, William Wah Yee
Master's Theses
BiOWiSHTM – Aqua is a blend of preserved multi-bacteria culture with the capability of denitrification. If an anaerobic nitrate rich activation procedure is used instead of the standard aerobic activation procedure, the denitrification rate is increased by 28 percent under the conditions of 30°C, 1C:1N, 200mg/L of carbon, and 200mg/L nitrogen.
Lipid Production By Microalgae Treating Municipal Wastewater, James Edward Kelley
Lipid Production By Microalgae Treating Municipal Wastewater, James Edward Kelley
Master's Theses
Microalgae hold much promise as a feedstock in liquid biofuel production. Lipid content of microalgae cells range from 30-80% dry weight of biomass. It is projected that microalgae can produce between 1,000-6,500 gallons/acre/year of oil. Currently, production of industrial algae operates in open raceway ponds that use minimal capital and energy inputs to culture algae. Raceway ponds can also be used to grow microalgae from municipal waste streams. Although high biomass productivity can be achieved in these systems, there remains a large production gap between large volumes of biomass cultivation and high lipid content from microalgae cells. Low lipid content …
Formulation Development Of A Polymer-Drug Matrix With A Controlled Release Profile For The Treatment Of Glaucoma, Eric W. Tsoi
Formulation Development Of A Polymer-Drug Matrix With A Controlled Release Profile For The Treatment Of Glaucoma, Eric W. Tsoi
Master's Theses
Glaucoma is the leading cause of blindness in the United States accounting for 9-12% of all cases of blindness. Currently, the front line treatment for glaucoma are prostaglandins that may have to be taken up to several times a day. Even with proper treatment, roughly 11% of the patients using the treatment are non-compliant and lose their vision. In this project, ForSight Laboratories has developed a pharmaceutical drug delivering implant with the capability of sustaining long-term release of a prostaglandin as a new way to treat the condition. This project reports the product development of a polymer drug matrix with …
Conjugated Linoleic Acids Alter Body Composition Differently According To Physiological Age In Moulard Ducks, Jeff Fesler, Daniel Peterson
Conjugated Linoleic Acids Alter Body Composition Differently According To Physiological Age In Moulard Ducks, Jeff Fesler, Daniel Peterson
Master's Theses
Conjugated linoleic acids (CLA) have been shown to have remarkable yet inconsistent metabolic effects in mice, rats, hamsters, chickens, cattle, and humans. In particular, effects on lipogenesis vary with tissue, physiological state and specie. In this study we tested the hypothesis that CLA would differentially affect ducks of the same genetic background but of differing age. Growing (7 wk) and maintenance (11 wk) Moulard ducks were grouped by age and fed a standard diet supplemented with either 5% soybean oil (control) or 5% CLA isomer mixture. Animals were harvested after 3 weeks or 6 weeks for assessment of body composition …
Measuring The Counter/Assumption Model's Effect On Argumentation Quality, Evan D G Ovadia
Measuring The Counter/Assumption Model's Effect On Argumentation Quality, Evan D G Ovadia
Master's Theses
This thesis presents a new platform called See the Reason, built upon a tree- structured argumentation model called the Counter/Assumption model. In the Counter/Assumption model, a topic is posted first, then under that topic, reasons for and against, and for each reason, counterarguments, and for any counterargu- ment, more counterarguments. The model enables us to systematically determine whether a claim is “tentatively true” or “tentatively false,” in an effort to motivate people to make their side’s claims tentatively true and the opposing side’s claims tentatively false, thus encouraging conflict. Research suggests that debates with more conflict are better, so this …
