Monte Carlo Green's Function Formalism For The Propagation Of Partially Coherent Light, Scott A. Prahl, David G. Fischer, Donald D. Duncan

Electrical and Computer Engineering Faculty Publications and Presentations

We present a Monte Carlo-derived Green's function for the propagation of partially spatially coherent fields. This Green's function, which is derived by sampling Huygens-Fresnel wavelets, can be used to propagate fields through an optical system and to compute first- and second-order field statistics directly. The concept is illustrated for a cylindrical f/1 imaging system. A Gaussian copula is used to synthesize realizations of a Gaussian Schell-model field in the pupil plane. Physical optics and Monte Carlo predictions are made for the first- and second-order statistics of the field in the vicinity of the focal plane for a variety of source …

The Importance Of Interpersonal Discussion And Self-Efficacy In Knowledge, Attitude, And Practice Models, Joyee S. Chatterjee, Anurudra Bhanot, Lauren B. Frank, Sheila T. Murphy, Gerry Power

Communication Faculty Publications and Presentations

This study contributes to the theoretical discussions about the influence of education-entertainment programming on consumers of the genre. Data from the end-line evaluation of an EE program produced by the BBC World Service Trust in India, Jasoos (Detective) Vijay, is used. The analysis focused on 834 sexually active young men, the key demographic target audience for the program. Using structural equation modeling techniques, an initial knowledge, attitudes, and practices model is examined. Adding self-efficacy and interpersonal discussion improve this model. Not only is interpersonal discussion important, but the target others with whom that discussion occurs are also important for predicting …

The Incorporation Of Direct Democracy : Populism And Initiative Practices As Contested Terrain, Larry Galizio

Dissertations and Theses

What are the democratic implications of the increasing professionalization of direct democracy?

The dissertation takes a critical approach to the "initiative-industrial complex" and offers a counter-thesis to prevailing scholarly research on the substantial growth in the use of political consultants in initiative campaigns. The political economic analysis approaches direct legislation campaigns and elections as constituent parts of a system of legitimation for the existing set of social relations.

An historical analysis reveals that the contemporary era of initiative activity rivals that of its frequent use during the populist and progressive eras; and that in the early 21st century direct legislation …

Metamaterial Devices For The Terahertz Band, Gabriel Paul Kniffin

Center for Electron Microscopy and Nanofabrication Publications and Presentations

Terahertz (THz) and metamaterials are both hot topics in electromagnetics research. The THz band (0.1-10 THz) lies in the ‘gap’ between microwave and far infrared regions. Research is currently underway to characterize how these waves interact with matter, with potential applications including security screening, medical imaging, and non-destructive evaluation. Metamaterials are artificial materials containing sub-wavelength structures whose material properties, μ and ǫ can be ‘tuned’ to desired specifications, including simultaneously negative values, resulting in exotic properties such as a negative refractive index. Current metamaterials research includes the design of devices that operate at THz frequencies, filling a niche left wide …

"Green" Transportation Taxes And Fees: A Survey Of Californians, Asha Weinstein Agrawal, Jennifer Dill, Hilary Kathleen Nixon

Urban Studies and Planning Faculty Publications and Presentations

This report explores public opinion on a new and promising concept―green transportation taxes and fees. These are taxes and fees set at variable rates, with higher rates for more polluting vehicles and lower rates for those that pollute less. This approach to transportation taxes and fees adapts the traditional transportation finance system to achieve two critical public benefits at once: encouraging drivers to choose more environmentally-friendly transportation options and raising revenue for needed transportation programs. To test public support for green transportation taxes and fees, the authors conducted a random telephone survey of 1,500 Californians that asked respondents their views …

Tax Competition In The Film Industry, Chelsea Villareal

Anthós

Being one of the largest industries in the world, the film industry remains an economic powerhouse in our society. It’s for this reason that film’s messages are not the only political aspects of their creation. Senators and representatives across the country are increasingly seeing the film industry as key towards economic development. With incentive packages being placed around the country, the politics over the film industry have become an overwhelming power game. Politicians are being threatened with recalls and impeachment to keep their economies afloat during harsh economic times. Without raising taxes, representatives have hit a wall. Increasing debt and …

Active Site Chemistry Of The Nadph-Dependent:7-Cyano-7-Deazaguanine (Preq0) Nitrile Oxidoreductase, An Enzyme Involved In Queuosine Biosynthesis, Bobby Wai Keung Lee

Dissertations and Theses

Queuosine (Q) is a modified nucleoside found at the wobble position of bacterial and eukaryotic transfer RNAs (tRNAs) that are specific for the amino acids tyrosine, histidine, aspartate and asparagine. A recently discovered enzyme in the biosynthetic pathway of Q, the NADPH-dependent 7-cyano-7-deazaguanine oxidoreductase (QueF), carries out the two-fold, four-electron reduction of Q precursor preQ0 to preQ1 and represents the first example of the enzymatic conversion of the nitrile functional group to an amine. Presented herein are kinetic, spectroscopic, mutational, biophysical, and isotope labeling studies directed at the elucidation of the chemical and kinetic mechanisms of this new class of …

Primary Care, Males, Masculinity, And Suicide : A Grounded Theory Study, John Thomas Casey

Dissertations and Theses

Suicide completion in the United States is a public health problem that claims over 30,000 lives annually. Most of these suicide victims are white males who die by firearm, and who typically are not taking antidepressant medication and are not involved in mental health treatment at the time of death. Depression is closely linked to suicide death, and treatment for depression is provided mainly within primary health care settings where most suicide decedents have been seen at some point in the year prior to their death. The rate of male depression is likely under-reported, partly due to gender-bias within primary …

Prediction Of Persistence Of Fertilizer-Derived Cadmium In Oregon Agricultural Soils Using Equilibrium Modeling And Fertilizer Release Kinetics, Fungai Mukome

Dissertations and Theses

Organic farming has become a multimillion dollar industry and while much emphasis is put on subsequent fertilizer inputs onto these fields, very little consideration is given to the prior fertilization activities of these soils. For a farm to be certified organic it means no harmful chemicals have been applied for at least three years.

The overall hypothesis tested by this research was that equilibrium adsorption models can adequately represent the behavior of fertilizer-derived cadmium in Oregon agricultural soils and that such model results can be easily incorporated into risk assessment models, transport study models and persistence studies for organic or …

Harlot: A Revealing Look at the Arts of Persuasion

This short essay compares the war-time rhetoric of George W. Bush with the rhetoric of Barack Obama. The eerie similarities between the two lead me to question Obama's promise of change.

Comic Fans And Convergence Culture: Community Of Readers In The Master Of Kung Fu, David Edward Beard, Kate Vo Thi-Beard

Harlot: A Revealing Look at the Arts of Persuasion

As a member of several fan cultures, I have an interest in the processes that fan audiences use to construct and reconstruct the texts they consume. Additionally, I think of the way (written, oral, and musical) texts construct the individuals who constitute their audiences. Examining Master of Kung Fu provided the perfect combination of these two interests. -- David

My fascination with representations of Asians in the media began with The Destroyer book series that I read as a teen. While the character Remo at first resisted his fate, he quickly embraced his identity as the next Master of Sinanju. …

Toward Death And Violence – Rhetorical And Creative Potential; A Reader's Text, Giovana Driussi

Harlot: A Revealing Look at the Arts of Persuasion

I wrote this essay for readers, hoping to provoke, inspire, enrage and enjoy. Death and violence have been painful and productive forces in my life, and specifically in my writing. In this essay I share some of these experiences and relate them directly to writing, as well as public, political, rhetorical, and historical topics. My desire is to affect personal and public reflection, and to display rhetorical agency in both spheres, thus demonstrating that such divisions, and most if not all binaries, are social constructs that beg for challenge.

I, Barack Hussein Obama: Virtual Crowds And Participatory Politics In The 2009 Inauguration, Elizabeth Losh

Harlot: A Revealing Look at the Arts of Persuasion

Pundits in the mainstream media have a tendency to chastise Internet users for making their private lives public and for putting the most intimate or mundane details of their personal experiences into digital files for all to gawk at online. As a scholar of rhetoric, my fear is that these practices won't be public enough now that so many people rely on corporate cloud computing to store and share photos, videos, and journal entries, and social network sites often function as the Internet equivalent of gated communities. At the same time corporate copyright regimes are claiming intellectual property rights to …

Large-Scale Assembly Of Periodic Nanostructures With Metastable Square Lattices, Chih-Hung Sun, Wei-Lun Min, Nicholas C. Linn, Peng Jiang, Bin Jiang

Mathematics and Statistics Faculty Publications and Presentations

This article reports a simple and scalable spin-coating technique for assembling non-close-packed colloidal crystals with metastable square lattices over wafer-scale areas. The authors observe the alternate formation of hexagonal and square diffraction patterns when the thickness of the colloidal crystals is gradually reduced during spin coating. No prepatterned templates are needed to induce the formation of the resulting metastable crystals with square arrangement. This bottom-up technology also enables the large-scale production of a variety of squarely ordered nanostructures that are consistent with the industry-standard rectilinear coordinate system for simplified addressing and circuit interconnection. Broadband moth-eye antireflection gratings with square lattices …

Inflammatory Biomarkers And Subclinical Atherosclerosis In African-American Women With Systemic Lupus Erythematosus (Sle), Edith M. Williams, Carlos J. Crespo, Joan Dorn

Community Health Faculty Publications and Presentations

Women with lupus are at increased risk for developing cardiovascular disease (CVD). Previous studies of atherosclerosis in SLE have not been representative of the minority groups most affected by lupus and its complications. Therefore, a study of 41 lupus cases and 83 controls was conducted to investigate the relationship between carotid atherosclerosis and inflammation in African-American women. Participation consisted of a questionnaire, physical examination, fasting blood draw, and ultrasound of the carotid arteries. There were observed differences between cases and controls with regard to carotid intima media thickness (IMT) and traditional cardiovascular risk factors, although few reached statistical significance. Tumor …
