Erasing Mexican Chicago: The Role Of Community Based Organizations And Immigrant Networks In The Gentrifying Neighborhood Of Pilsen, David Orta

Master's Theses

This study explores the effects of gentrification in Chicago's Pilsen neighborhood, a historic port of entry for Mexican immigrants and a basin for community organization and other resources. The research questions of this study first query the effects of gentrification on the informal immigrant networks that make Pilsen a site for community resources for new immigrants. Second, the study explores the effects of gentrification on community-based organizations in a rapidly changing environment. As the racial and economic demographics of the neighborhood shift, community based organizations must adapt. Finally, this study examines the relationship between neighborhood residents and community based organizations. …

Fish Assemblage Structure In Natural, Channelized, And Restored Sections Of Nippersink Creek, Mchenry County, Illinois, Sarah Ann Zack

Master's Theses

Degradation of aquatic habitats and loss of biodiversity are growing concerns of natural resource managers and the general public. Channelization, the common historical practice of straightening streams and rivers for agricultural interests, has had profound detrimental effects on the biodiversity of lotic fish assemblages. Nippersink Creek, McHenry County, IL is a twenty-three mile stream that flows through an area valued for its fish, wildlife, and invertebrate biodiversity. Although a portion of the stream was channelized in the 1950's, restoration efforts by the McHenry County Conservation District have recently restored historical meanders. Nevertheless, efforts to restore streams and rivers to their …

Temporal Variability Of Bioassessment Indices Used To Evaluate Three Midwestern Streams, Nia M. Haller

Master's Theses

Population, community and functional measures or metrics in rapid bioassessment programs aid in establishing biological criteria for streams and rivers. Each metric measures different aspects of community structure and is important in detecting changes in macroinvertebrate community structure that are influenced by changes in water quality. In this study, temporal variation of nine commonly used bioassessment indices was examined in three midwestern streams. The indices were calculated for each of nine replicate benthic macroinvertebrate samples collected monthly for one year from Cowpie Creek (CC), Nippersink Creek (NC) and Lawrence Creek (LC), McHenry County, Illinois. In practice, the habitat sampled for …

Resource Composition And Macroinvertebrate Resource Consumption In The Colorado River Below Glen Canyon Dam, Holly Ann Alfreda Wellard Kelly

Master's Theses

Physical and biological changes to rivers induced by large dams can significantly alter downstream communities, decreasing the biotic integrity of these rivers. For example, completion of Glen Canyon Dam on the Colorado River in 1963 has altered the downstream ecosystem and contributed to the decline of native fish populations and dramatic changes in the macroinvertebrate communities. Physical changes associated with the dam may also influence the food resources supporting macroinvertebrate production, but this has not been previously measured. For example, autochthonous production is high in the clear tailwaters of the dam, but downstream tributary allochthonous carbon inputs are substantial and …

Morphological Development Of The Axial Skeletons Of Esox Lucius And Esox Masquinongy (Euteleostei: Esociforms), With Comparisons In Developmental And Mineralization Rates., Amanda Maria Burdi

Master's Theses

Developmental morphology of the axial skeleton of Esox lucius (i.e., northern pike and type species) and E. masquinongy (i.e., muskellunge) was investigated. More than 1,000 specimens were examined ranging in size from approximately 10 mm notochordal length (NL) post-hatching juveniles to over 80 mm standard length (SL) foraging sub-adults. Results show that regardless of individual variation, the relative sequence of bone formation and mineralization is consistent between the two species. This consistent developmental pattern enabled construction of an ontogenetic staging scheme of eight developmental stages, each characterized by one defining criterion. The first appearance in cartilage and/or first sign of …

Structure-Function Relationship Studies Of The Udp-Glucose Pyrophosphorylase From Escherichia Coli, Agnieszka Maria Orlof

Master's Theses

UDP-Glucose Pyrophosphorylase (UDP-Glc PPase) is a key enzyme of the carbohydrate metabolic pathway widely used among prokaryotes and eukaryotes. In plants, UDP-Glc PPase is necessary for sucrose synthesis while mammals utilize this enzyme for the production of glycogen. A bacterium such as Escherichia coli uses UDP-Glc PPase for biosynthesis of the lipopolysscharide core which forms a cell wall.

This study focused on UDP-Glc PPase from Escherichia coli which is encoded by both galU and galF genes. The first part of this project investigated amino acids that could play an important role in the function of UDP Glc PPase (GalU). Based …

Diet Overlap And Competition Among Native And Non-Native Small-Bodied Fishes In The Colorado River, Grand Canyon, Arizona, Sarah Ellen Zahn Seegert

Master's Theses

Introductions of non-native fishes are threatening native fish communities in streams and rivers across the United States. The Colorado River especially has experienced numerous species invasions, and native fish populations throughout the basin are in decline. The native fish community in the Grand Canyon has been particularly affected, with half of the native fishes extirpated from the canyon. Many scientists blame interactions with non-native fishes for these declines. However, to date no one has conducted a thorough diet analysis of small-bodied fishes in the system to assess overlap between native and non-native fish diets. I analyzed the diets of native …

Anti-Nogo-A Immunotherapy Facilitation Of Environmental Enrichment's Effects On Recovery From Stroke In The Aged Rat, Sarah Jane Hein

Master's Theses

Stroke and traumatic brain injury are devastating disorders that often lead to permanent neurologic deficits, with few available treatment options once injury has occurred. In previous work, Anti-Nogo-A immunotherapy has been shown to neutralize the neurite inhibitory protein, Nogo-A, and to promote neuronal plasticity and improve functional recovery after stroke in the rat. Furthermore, other reports have demonstrated that environmental enrichment improves functional recovery in rodents following stroke. Our previous work demonstrated that anti-Nogo-A immunotherapy also helps promote cortical plasticity in the rodent. In the current project, we examined two methods to promote recovery after brain injury, a stroke model …

Functional And Phenotypical Analysis Of The Effects Of Aging On B Cells And Their Bone Marrow Microenvironment, Nicole May Ziegler

Master's Theses

Aging impacts multiple organ systems, and specifically causes the immune system to lose its ability to efficiently fight off infections. Regarding immunity, aging research predominantly focuses on the adaptive immune system. B cells, which mediate the humoral arm of the adaptive immune system, develop throughout life in the bone marrow where microenvironmental `niches' are important. The bone marrow does not exactly `atrophy' with age; however, studies comparing young and old mice demonstrate an age-related change in the bone marrow B cell subpopulations.

The overall goal was to determine if femoral and sternum bone marrow have different plasma cell composition and …

Identité Et Langue Française Chez Azouz Begag Et Chahdortt Djavann, Nehal Abuelata

Master's Theses

This thesis addresses the problematics of identity construction through the acquisition of the French language for immigrants living in France. More specifically, it examines the impact French language acquisition has had and still has on the identity of children of Maghrebian descent and, more generally, its influence on the identity of non-francophone immigrants who arrived in France as adults by examining the novels of two francophone authors: Azouz Begag and Chahdortt Djavann. Whereas the former is a French writer of Algerian descent, a "Beur," the latter is an Iranian-born writer who emigrated to France as an adult. In addition, this …

A Phonetic, Phonological, And Morphosyntactic Analysis Of The Mara Language, Michelle Arden

Master's Theses

This thesis presents a linguistic analysis of the Mara language, a Tibeto-Burman language spoken in northwest Myanmar and in neighboring districts of India. Data has been gathered through interviews with a native speaker. The analysis includes a full phonetic segment inventory of the dialect and a phonological analysis of contrastive sounds and contextual variants. Sound files embedded in the document illustrate the phonetic system. Mara's distinctive phonetic features include the loss of word-final consonants, a set of voiceless sonorants, pre- and post- aspirated nasals, and lowered and unlowered vowel pairs. The morphosyntax of Mara pronominal words demonstrates a split-ergative case …

Interannual Differences In The Estuarine Ghost Shrimp, Neotrypaea Californiensis, Michael Buncic

Master's Theses

The dispersal of invertebrate marine larvae can be expected to be wide ranging and show little population structure. Neotrypaea californiensis, the burrowing ghost shrimp, is found throughout the waters and coastal estuaries of the northwestern United States. Three hundred and four larval samples were used to study population diversity and structural difference occurring over the course of spawning periods from June to September in successive years (2005 and 2006). Data and genetic analysis from nucleotide sequencing of a section of the mitochondrial Cytochrome C oxidase subunit I (COI) gene suggest that ocean-borne larvae off the coast of Oregon and Washington …

Distribution, Abundance, Growth, And Habitat Use Of Steelhead In Uvas Creek, Ca, Joel Malone Casagrande

Master's Theses

Distribution, abundance, growth, and habitat use of juvenile steelhead (Onorhynchus mykiss) were studied in a central California stream under two increased summer flow reservoir release strategies. The effect of habitat quality (including longitudinal changes in flow, water temperature, canopy closure, substrate quality, and turbidity) on abundance and growth of steelhead among sites was determined. Increased stream flow extended rearing habitat and steelhead distribution downstream to reaches that previously would have been dry. Yearling or older steelhead were relatively scarce at all Uvas Creek sites. Steelhead were most abundant, but small, in the upstream half of the study reach, …

Valley Of Heart's Delight: Orchards To Hard Drives In The San Jose Mercury News, Megan Lynn Alpers

Master's Theses

This research was conducted to explore how the San Jose Mercury News (formerly San Jose Mercury Herald) covered the Santa Clara Valley's transition from an agricultural community known as "The Valley of Heart's Delight" to Silicon Valley, focusing on the changes made in the reporting of farm and ranch news.

The time period surveyed in this thesis is from 1935 to 2000. The purpose was to establish any changes to reporting agricultural news over the years. A social history of agricultural journalism in the San Jose Mercury News over a 65-year period provided insight into how the farming industry was …

Nonlinear Pushover Analysis Of A One-Story Precast Concrete Cladding System, Kai Sum Cheung

Master's Theses

A nonlinear pushover analytical study of a precast concrete cladding system was completed. The analytical software used was SAP2000 (version 11.0.0). The specimen modeled is the three-dimensional corner of the first floor of a nine-story building. Thirty-one linear and nonlinear link elements were used to simulate the cladding connections. The results showed that inelastic behavior of these connections controls the behavior of the overall cladding system. At drift ratios of 0.0104, closure of the sliding connections at the top of the column cover panels occurs and resisting forces climb significantly with small additional lateral displacement. Forces quickly rise to levels …

The Response Of Zigadenus Fremontii To Variation In Fire Regime, Shannon Elizabeth Dinis

Master's Theses

California's chaparral shrub communities are naturally exposed to dry-season fire. It could be reasoned that prescription burns set during the wet season by land managers would have more detrimental effects on plant regeneration than dry season fires because wet season burns are more likely to kill newly emergent seedlings and damage newly emerged leaves of mature plants. Six field sites with flowering Zigadenus fremontii, an herbaceous perennial geophyte common to chapparal and part of the post-fire bloom, were established at Henry W. Coe State Park in Nothern California. Three sites were part of the September 2007 Lick Wildfire and …

Western Pond Turtle Summer Habitat Use In A Coastal Watershed, Jae Abel

Master's Theses

Western pond turtle (Actinemys marmorata) habitat use was studied in a coastal pond, lagoon, and stream system during the summer of 1995 and 1996 at Waddell Creek, Santa Cruz County, California. Location and habitat association data were recorded for locations and sightings of radio-tagged and un-tagged turtles during the normal active season. Summary comparison of habitat associations and habitat availability provided inference of habitat preference at several habitat scales. For most of the active season the turtles were in relatively sunny aquatic habitat, in deeper, slower velocity water. In addition, the turtles were most commonly associated with exposed …

An Analysis Of Stacy Garrop's Sonnet Settings For Treble Choir And Piano, Kathryn Alexis Feetham

The purpose of this thesis is to provide a thorough and detailed analysis of Stacy Garrop's two works for treble chorus and piano, Pity Me Not (2003) and Thou Famished Grave (2006) for the purposes of providing a base for future research and study. Since Garrop's goal as she composes is to tell the story contained in the text, this analysis of her works looks closely at the approaches she takes to communicate the story to the listener. The two choral pieces are examined on several musical levels including but not limited to form, melody, harmony, register, rhythm, tempo, meter, …

Synthesis Of A Potentially Insulin-Mimetic, Lipid-Linked Inositol Glycan, Meenakshi Goel

Master's Theses

Inositol glycans (IGs) are naturally occurring oligosaccharides that can stimulate insulin sensitive cells. Several synthetic IG analogues have been shown to activate the insulin-signaling pathway, including the stimulation of the enzyme pyruvate dehydrogenase (PDH) phosphatase that can further stimulate aerobic metabolism in cells. Cancer cells shift to anaerobic metabolism in order to escape intrinsic apoptosis (Warburg Effect). IG's ability to stimulate aerobic metabolism might provide a method to reverse the Warburg Effect and thereby induce apoptosis in the cancer cells. One specific palmitoylated IG analogue has been shown to selectively kill cancer cells while having no adverse effect on normal …

Surface Plasmon Studies Of Composition Control In Mixed Acid Alkanethiol Sams, Arthur Cheng

Master's Theses

In this study, surface plasmon resonance (SPR) was used to investigate the adsorption of MUA (11-mercapto-undecanoic acid), MPA (3-mercapto-propionic acid) and MHX (6-mercapto-1-hexanol) onto a gold SPR sensor surface. MUA, MPA, and MHX were dissolved in phosphate buffers of ionic strengths varying from 0.1 mM to 1 M and at pH values between 2 and 11, and monolayer formation experiments were performed. Our results illustrate how the adsorption of these charged and neutral alkanethiols depends on solution ionic strength and pH. Results indicate that, for single-component MUA or MPA layers, low pH and elevated solution ionic strength may promote denser …

Library Services In U.S. Immigration Detention Facilities, Stephanie Lan Chin

Master's Theses

The thesis explores the current state of library services in facilities in which U.S. Immigrations and Customs Enforcement (ICE) houses immigrant detainees, including (1) Bureau of Prison (BOP) facilities, (2) contracted detention facilities (CDF), (3) ICE-owned facilities (often called Service Processing Centers, or SPC's), and (4) Intergovernmental Service Agreements (IGSA) facilities. The study was based on a survey that was mailed to 356 facilities that detain immigrants by or on behalf of ICE. The results of the survey were used to determine the current status of library services in immigration detention facilities as well as to identify issues or problems …

Toward A Single-Consciousness: Challenging "Un-American-Ness" Of People Of Color, Bhawana Kamil

Master's Theses

Race is a major axis of social injustice in America. Social injustice is due to both maldistribution of material resources and opportunities and non-recognition or mis-recognition of people of color. One form of mis-recognition is the accusation that a person of color is not a real American, creating a conflict of identities (i.e., racial and American): a double-consciousness. This accusation has its origins in faulty ideas about race, identity, and race-group membership.

This paper presents a new model of identity that addresses these faulty ideas and provides a conceptual structure within which one can consistently maintain a single-consciousness while maintaining …

Social Support As Moderator Of Job-Specific Or Generic Stressors With Strains, Kaci Deeana Mabe

Master's Theses

Two studies examining the relationship between job-specific stressors and strains versus the relationship between generic stressors with strain, as well as the moderating role of social support (from coworkers and administrators), are presented. Eighteen primary school teachers from a private Jewish day school (Study 1) and 242 teachers from an Arizona school district (Study 2) completed self-administered surveys. Results indicated that job-specific (vs. generic) stressors had a stronger positive relationship with strains, but social support was a better moderator for the relationship between generic stressors and strain. As hypothesized, administrator support had a reverse-buffering effect on the stressor-strain relationship in …

If I Could Choose: Internalized Homophobia Of The Queer Cinema Movement, James Joseph Flaherty

Master's Theses

This thesis offers a critical examination of essentialist and constructionist theories of queer identities, with emphasis on portrayals of internalized homophobia in film. The thesis examines three films released at the latter part of the first New Queer Cinema movement (1991 - 2000) - American Beauty (1999), Urbania (2000) and Velvet Goldmine (1998). Using criticisms of Queer as performativity, as theorized by Judith Butler, in addition to the works of Gregory M. Herek, Harry M. Benshoff, Jeffrey Weeks, and other theorists and academics, the thesis analyzes the use of characterization, mise-en-scene, and spatial and temporal relationships in these films as …

Flow Cytometry Of Alexandrium Catenella From Elkhorn Slough, California., Phillip Roland Hawkins

Master's Theses

This study describes the use of flow cytometry for the enumeration of the toxic marine dinoflagellate Alexandrium catenella in both estuarine samples from Elkhorn Slough, California and from sea water samples from inner Monterey Bay. Samples were subjected to a density-barrier sample enrichment technique employing percoll to separate debris from phytoplankton prior to sample fixation, labeling and analysis. Clarified, enriched preparations of phytoplankton were subjected to whole cell Fluorescent In Situ Hybridization (FISH) using a ribosomal DNA (rDNA) probe specific for the North American ribotype (NA1) of the dinoflagellate genus Alexandrium and analysis by flow cytometry. Flow cytometry was validated …

Preparation Of Carbon Nanotube Based Device And Its Electrochemistry, Weiling Hsieh

Master's Theses

The purpose of this research is to develop methodologies for the exploitation of carbon nanotube thin films as chemical and electrochemical sensors. In this study we prepared thin films of carbon nanotubes (CNT) by solution casting methods and then used a novel hybrid electrochemical-conductometric method to measure the CNT film electrical conductivity as a function of electrochemical bias and stimulus. The bias between the CNT film and the contacting electrolyte and the bias between the opposite ends of the CNT film (referred to as K1 and K2) were simultaneously controlled - analogous to a transistor with an electrolyte gate. A …

Who Am I?: The Reflexivity Of Self-Identity Through Tourism, Matthew Lee Milde

Master's Theses

This study has set forth to close gaps, explore innovative methods, and create a better understanding of "Who am I?", in tourism research. Few studies in tourism research focus on how experiences gained from traveling shape self-identity through personal biographies. Building on the work of seminal authors on self-identity, personal narrative, and tourism, this study explores the reflexivity of self-identity as represented in travel narratives. The lived experiences offered through narrative condition spontaneous instances of self-discovery allowing for the (re)creation of new self-identities.

Participants were selected through a snowball sample; in-depth interviews were held with fifteen (15) adults born and …

Family Of Circulant Graphs And Its Expander Properties, Vinh Kha Nguyen Tran Nguyen

Master's Theses

In this thesis, we apply spectral graph theory to show the non-existence of an

expander family within the class of circulant graphs. Using the adjacency matrix and its properties, we prove Cheeger's inequalities and determine when the equalities hold. In order to apply Cheeger's inequalities, we compute the spectrum of a general circulant graph and approximate its second largest eigenvalue. Finally, we show that circulant graphs do not contain an expander family.

Where's My Daddy? Effects Of Fatherlessness On Women's Relational Communication, Latoya Marie Jackson

Master's Theses

The purpose of this thesis research was to understand the relationship between father absence and women's communication styles in romantic heterosexual relationships under social cognitive theory. Two studies were conducted using a multi-method research approach in order to triangulate the results. Seven fatherless women were interviewed to arrive at a better understanding of how father absence informed their romantic relational experiences. Specifically, the topics of relationship roles, self-disclosure, expression, and self-silencing in romantic relationships were examined in the interviews. Participants reflected on what growing up fatherless meant to them and whether or not this had any influence on the role …
