The Effect of Cathode Rays on Metal Surfaces

Metal surfaces which have been bombarded with cathode rays and those which have not been so bombarded, react differentially toward chemical vapors. Surfaces which have been rayed through a stencil and developed in certain vapors, reveal the image of the stencil pattern. It was desired to protect the unrayed areas with an inactive and nonconducting coating. The rayed areas should then acquire a deposit when the specimen is electroplated. This was best accomplished by development in the absence of air, with ionized organic vapors. Attempts were also made to raise the surface of the rayed regions directly. Preliminary experiments indicate the development with metallic vapors, in the absence of air

Images of the Modern Immigrant: Persuasive Metaphors Presented in U.S. American Newspapers

Inspired by the recent implementation of the Arizona Immigration Law SB 1070, this study examines the use of metaphor as a persuasive technique in U.S. American newspapers. In particular, the metaphors are examined to see how they have affected views of Latino immigrants. The research examines two popular newspapers with six articles from The New York Times and five from The Washington Post. The data analysis discovered four primary metaphors present across popular newspaper rhetoric including: the immigrant as alien, the immigrant as criminal, the immigrant as river, and the immigrant as victim. Analysis of these metaphors reflects a shift in newspaper rhetoric towards a more realistic portrayal of the immigrant

Encountering El Tigre : jaguars, knowledge, and discourse in the Western world, 1492-1945

The jaguar is one of the most charismatic species found in the Western Hemisphere, and its presence has long resonated with human communities. Throughout history these large spotted cats have evoked a myriad of responses, from reverence and respect, to fear and disdain. Situated within ongoing re-examinations of the place of animals in public discourse, this dissertation examines representations of jaguars from the fifteenth through twentieth centuries, exploring the ways in which knowledge about this species was constituted in the Western world within the evolution of scientific thought and natural history. Locating the jaguar at the intersections of nature, science, and culture, this dissertation is concerned with the ways this elusive species’ animality was constructed and represented. Records produced by Europeans in the New World demonstrate the dynamic ways in which humans imagined the jaguar’s physical form, interpreted their actions, characterized their feline-ness, and ultimately, attempted to locate these cats within their own notions of natural order. Loaded within these accounts from the outset are notions of value, which are as fluid as the positions these cats occupied in ecological, biological, and imaginary landscapes of the New World. This dissertation examines accounts from prominent explorers, scholars, scientists, authors, and artists, all of whom sought to represent jaguar lives. Drawing from accounts of explorations, guides produced by naturalists, scientific reports, and the letters and journals of those who traveled through the shared margins, these chapters locate the jaguar at the center of its own natural history. These jaguars are a connective thread moving through the span of post-contact natural history, and they keep notable company: from Cortés to Balboa; Alexander von Humboldt to Charles Darwin; and Theodore Roosevelt to Aldo Leopold. All of these men published tales of the jaguar that circulated widely through Western Europe and the United States, playing a significant role in the production of jaguar knowledge. In so doing, the jaguar’s tale become one that operates across scales of time and space, simultaneously immediate and localized within these encounters and yet timeless and global, embedded within global circulations of information and power.Geography and the Environmen

How Queer Came to Be: Deconstructing White Queerness in Melville\u27s Bartleby, Ginsberg\u27s Howl, and Morrison\u27s A Mercy

In American LGBTQ+ communities, questions continually arise about what it means to live in a post-gay marriage world. Is there still a need for a division between LGBTQ+ and heteronormative spaces, such as nightclubs or parades? What purpose does the ideological signification of a queer identity serve if, ostensibly, queer communities are now equal with their heteronormative counterparts? Rather than accepting the homonormative, post-gay marriage premise that underlies frequent, current representations of “queerness” in terms of white, male, gay bodies, I plan to explore the convergence of aesthetics and politics as a method of freeing queer theory from some of its temporal binds and fears of anachronism and presentism. In doing so, I hope to illustrate how the formation of a future for queer theory and queer identity must also address the violent, racist background of identity in America, and specifically, queer theorists must address how literature served to codify the queercoding of racialized spaces that became the underlying foundation of the confining white closet from which the majority of queer theory has emerged. I will return to the American literary past and re-interpret Herman Melville, Allen Ginsberg, and Toni Morrison in new ways that demonstrate how the intersections of language, queer identity, and space both uphold and dismantle patriarchal and racist hierarchies

Psychosocial factors predicting first-year college student success

This study made use of a model of college success that involves students achieving academic goals and life satisfaction. Hierarchical regressions examined the role of six psychosocial factors for college success among 579 first-year college students. Academic self-efficacy and organization and attention to study were predictive of first semester grade point average (GPA) when controlling relevant demographic factors. Academic self-efficacy was even predictive of end-of-year GPA when controlling previous, first-semester GPA. Mediation analyses revealed that first-semester GPA was an important mediator between these two psychosocial variables and end-of-year GPA. Additional psychosocial variables were predictive of college students’ life satisfaction: stress and time management, involvement with college activity, and emotional satisfaction with academics. We explore how formulating interventions on the basis of psychosocial factors offers an avenue for students to address specific attitudes, emotions, and behaviors that relate to college success

Effectiveness of Flow Sheet Implementation on Diabetes Progression Screening at a Student-Run Free Clinic

Introduction. Diabetes mellitus (DM) disproportionately affects people with low socioeconomic-status (SES). Student-run free clinics (SRFC) aim to care for low SES populations and experience high clinician turnover. Flow sheets have been used to improve care for those with diabetes, yet no research has assessed the use of such a flow sheet in a SRFC. The aim of this project was to determine if use of a flow sheet improved care for people with DM in an SRFC. Methods. Charts from all patients receiving care for DM at one SRFC in the year before (n=53) and after (n=56) implementation of the flow sheet were reviewed. Pre and post group comparisons and post subgroup comparisons were made for glycosylated-hemoglobin (HgbA1c), microalbumin, and foot and eye exams. Results. During a one-year period, a larger proportion of patients who received care post flow sheet introduction received at least two HgbA1c tests (53%), a microalbumin test (46%), and a foot-exam (46%) compared to those receiving care before the flow sheet (28%, 2%, and 25%, respectively). There was no difference in proportions of patients undergoing eye exams. In post subgroup analysis, flow sheets were used for 50% of patients, and patients who received care with the flow sheet were more likely to receive at least two HgbA1c tests and a foot exam per year. Conclusions. Our study suggests that flow sheets can improve the process of care for patients with diabetes in a SRFC. A systematic integration of the flow sheet is being implemented in the SRFC now
