Rapid Evaluation Of Canola Lines For Cold Soak Filterability In Biodiesel, Hongjian Lin

Agribusiness and Biosystems Engineering

Worldwide concerns about fossil fuel depletion and energy security have recently triggered a research interest in biodiesel, which is renewable, biodegradable, and has several other advantages as an alternative to petro diesel. However, biodiesel may cause engine problems, especially fuel filter plugging, associated with its use in cold weather conditions. Trace contaminants such as glycerin, saturated monoglycerides (SMG), and soap compromise cold weather performance of biodiesel. A cold soak filtration test was recently included in the U.S. specifications for biodiesel (ASTM D 6751-09) to evaluate biodiesel cold weather performance. Canola seed has good potential to be a locally important biodiesel …

Serum Antibodies To Human Papillomavirus Type 6, 11, 16 And 18 And Their Role In The Natural History Of Hpv Infection In Men, Beibei Lu

USF Tampa Graduate Theses and Dissertations

Our understanding of humoral immune response to human papillomavirus (HPV) infection has been mainly derived from studies in women. Very little is known about humoral immune response to HPV in men. There is also a growing interest in understanding the burden of HPV exposure in the subgroups of the male population, including men who have sex with women (MSW), men who have sex with men (MSM) and men who have sex with both men and women (MSMW). This dissertation was undertaken to understand and characterize humoral immune response, measured by detectable serum antibody IgG, to HPV 6, 11, 16 and …

School Choice At The Crossroads Of Race, Class, And Accountability: An Analysis Of The Effects Of Voluntary School Choice On Elementary Schools In A Large District In The Southeastern United States, Teresa Craig Evans

USF Tampa Graduate Theses and Dissertations

In recent years, the responsibility for the desegregation of American public schools has transitioned from federal court mandates to school board programs and policies. There is widespread belief that this has resulted in the resegregation of schools across the country. One popular policy that is purported to provide the opportunity for voluntary integration, along with accountability for academic quality, is school choice. The purpose of this study was to consider the implications of such a policy in one large school district. There is an extensive body of research exploring who participates in school choice, how they make their choices, and …

Review Of Three Recent Randomized Trials Of School-Based Mentoring: Making Sense Of Mixed Findings, Marc E. Wheeler, Thomas E. Keller, David L. Dubois

School of Social Work Faculty Publications and Presentations

Between 2007 and 2009, reports were released on the results of three separate large-scale random assignment studies of the effectiveness of school-based mentoring programs for youth. The studies evaluated programs implemented by Big Brothers Big Sisters of America (BBBSA) affiliates (Herrera et al., 2007), Communities in Schools of San Antonio, Texas (Karcher, 2008), and grantees of the U.S. Department of Education's Student Mentoring Program (Bernstein et al., 2009). Differences in the findings and conclusions of the studies have led to varying responses by those in practice and policy roles. The results of the BBBSA trial led the organization to undertake …

Communities Of Color In Multnomah County: An Unsettling Profile, Ann Curry-Stevens, Amanda Cross-Hemmer, Coalition Of Communities Of Color

School of Social Work Faculty Publications and Presentations

Existing data that informs decision making in Multnomah County inadequately captures the lived experiences of communities of color. Rarely do existing reports include dimensions of race and ethnicity. Much research has been undertaken without the involvement of those most affected by the decisions guided by the research. The impact is that communities of color are rarely visible at the level of policy. Data has been used to obscure and oppress rather than to empower communities and eliminate disparities. This is not acceptable, and leads to inequitable policy and devastating outcomes for people of color.

Why Beauty Still Cannot Be Measured, Ossi Naukkarinen

Contemporary Aesthetics (Journal Archive)

This article focuses on the question of whether the latest results achieved in sciences such as evolution studies and brain research can help us understand the nature of aesthetic judgments. It suggests that such approaches may offer interesting insights for understanding many problems in aesthetics, but for clarifying aesthetic judgments one needs a philosophical point of view. Aesthetic judgments cannot be proven right or wrong by scientific methods, and beauty or other aesthetic qualities cannot be directly measured. The “method” of both making and analyzing aesthetic judgments is discussion, and the article clarifies why this is still the case, even …

Musical Presence: Towards A New Philosophy Of Music, Charles Ford

Contemporary Aesthetics (Journal Archive)

Most recent writings about the philosophy of music have taken an analytic or linguistic approach, focusing on terms such as meaning, metaphor, emotions and expression, invariably from the perspective of the individual listener or composer. This essay seeks to develop an alternative, phenomenological framework for thinking about music by avoiding these terms, and by extrapolating from the writings of Hegel, Husserl, and Heidegger. On the basis of discussions of musical time, its multiple levels of matter, and its internal dialectics, the essay presents a particular understanding of “style” as the primary basis for mediation between production and reception. It concludes …

Theodore Roosevelt On Labor Unions: A New Perspective, Louis B. Livingston

Dissertations and Theses

Historical studies of Theodore Roosevelt's views about labor and labor unions are in conflict. This was also true of contemporary disagreements about the meaning of his labor rhetoric and actions. The uncertainties revolve around whether or not he was sincere in his support of working people and labor unions, whether his words and actions were political only or were based on a philosophical foundation, and why he did not propose comprehensive labor policies.

Roosevelt historiography has addressed these questions without considering his stated admiration for Octave Thanet's writings about "labor problems." Octave Thanet was the pseudonym of Alice French, a …

Somatization And Engagement In Mental Health Treatment, Teresa Chianello

Dissertations and Theses

Somatization, the presentation of physical symptoms without an identifiable cause, is among the most common problems in primary medical care. Treatment approaches are typically offered within the medical consultation interview once the medical provider distinguishes between physical and emotional etiology. This dualistic strategy is especially troublesome for patients whose physical complaints cannot be validated and who are recommended for only mental health therapy. The aim of this study was to examine how medical practitioners can instead motivate patients to consider both physical and emotional treatment. An analogue intervention consisting of an enhanced consultation interview was compared to a care as …

Expressive Motion Synthesis For Robot Actors In Robot Theatre, Mathias I. Sunardi

Dissertations and Theses

Lately, personal and entertainment robotics are becoming more and more common. In this thesis, the application of entertainment robots in the context of a Robot Theatre is studied. Specifically, the thesis focuses on the synthesis of expressive movements or animations for the robot performers (Robot Actors). The novel paradigm emerged from computer animation is to represent the motion data as a set of signals. Thus, preprogrammed motion data can be quickly modified using common signal processing techniques such as multiresolution filtering and spectral analysis. However, manual adjustments of the filtering and spectral methods parameters, and good artistic skills are still …

Polyaniline Nanofibers As The Hole Transport Medium In An Inverse Dye-Sensitized Solar Cell, Ian Brock Hesselsweet

Dissertations and Theses

In order to become a viable alternative to silicon photovoltaics, dye-sensitized solar cells must overcome several issues primarily resulting from their use of a liquid electrolyte. Much research has gone into correcting these shortcomings by replacing the liquid electrolyte with solid-state hole-transport media. Using these solid-state materials brings new difficulties, such as completely filling the pores in the TiO₂ nanostructure, and achieving good adhesion with the dye-coated TiO₂. A novel approach to addressing these difficulties is the inverse dye-sensitized solar cell design. In this method the devices are constructed in reverse order, with the solid-state hole-transport medium providing the nanostructure …

Extraction Of Small Boat Harmonic Signatures From Passive Sonar, George Lloyd Ogden

Dissertations and Theses

This thesis investigates the detection and classification of small boats using a passive sonar system. Noise radiated from a small boats consists of broadband noise and harmonically related tones that correspond to parameters in the boats engine and propeller. A novel signal processing method for detection and discrimination of noise radiated from small boats has been developed. There are two main components to the algorithm. The first component detects the presence of small boats by the harmonic tonals radiated from the boat propeller and engine. The second component was designed to extract the a signature from passive sonar data. The …

Seventh-Grade Curriculum In Probability (A Guide For Teachers), David Nganga Njenga

LSU Master's Theses

A review of the literature indicates that teachers try to make connections between experimental and theoretical probabilities while teaching their students, but these connections are often not very clear. This greatly increases misconceptions students have about probability. This thesis presents a treatment of teaching probability that is geared for seventh grade and intended to minimize the misconceptions that both teachers and students may have. We present a concise mathematical exposition of finite probability models as well as collection of examples and activities, so as to help teachers and students organize their thinking and minimize misconceptions. The various examples and activities …
