A New Technique For Firn Grain-Size Measurement Using Sem Image Analysis, N.E. Spaulding, D.A. Meese, I. Baker, P.A. Mayewski

Dartmouth Scholarship

Firn microstructure is accurately characterized using images obtained from scanning electron microscopy (SEM). Visibly etched grain boundaries within images are used to create a skeleton outline of the microstructure. A pixel-counting utility is applied to the outline to determine grain area. Firn grain sizes calculated using the technique described here are compared to those calculated using the techniques of Gow (1969) and Gay and Weiss (1999) on samples of the same material, and are found to be substantially smaller. The differences in grain size between the techniques are attributed to sampling deficiencies (e.g. the inclusion of pore filler in the …

The Role Of Distillers Dried Grains With Solubles In Sulfur Toxicity In Ruminants, Bryan Wayne Neville

Animal Sciences

One of the challenges with using ethanol co-products is the potential for increased dietary S concentration. Dietary S concentration has been implicated as a cause of polioencephalomalacia (PEM) in ruminants. The focus of this research was to evaluate PEM in ruminants fed distillers dried grains plus solubles (DOGS) based finishing rations. Two separate hypotheses were formed: 1) Providing increased dietary thiamin will decrease the incidence of PEM in lambs fed increased S diets without affecting animal performance; and 2) Feeding DDGS would increase concentrations of H2S gas and incidence of PEM compared to diets based on dry-rolled com. Two studies …

Workplace Nutrition And Exercise Climate: Scale Development And Preliminary Model, Joseph J. Mazzola

USF Tampa Graduate Theses and Dissertations

Obesity is a major concern in the United States and has a multitude of negative physical and mental health consequences. Proper nutrition and exercise are important elements to initiating and maintaining a healthy lifestyle. Since most people spend a large amount of their time working, it is important that organizations create an atmosphere that is conducive to employees being able to eat healthy diets and exercise regularly. The social and environmental climate in terms of health was examined through the construct of a Workplace Nutrition and Exercise Climate (WNEC), defined here as the situational, social, and environmental factors within an …

Constraining Basin Geometry And Fault Kinematics On The Santo Tomás Segment Of The Agua Blanca Fault Through A Combined Geophysical And Structural Study, Adam Springer

USF Tampa Graduate Theses and Dissertations

The Agua Blanca fault is a major transverse structure of northern Baja California, extending more than 120km east from the Punta Banda ridge near the city of Ensenada to the San Matais Pass in central Baja. Through much of its eastern extent slip on this fault appears to be pure strike slip, however, at the Valle de Santo Tomás the fault makes a ~25°; change in orientation, which coincides with the formation of extensional basins on the fault. Recent evidence of the independent movement of the Baja Micro-plate relative to a stable Southern California Black leads to several possible hypotheses …

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones

Institute for Sustainable Solutions Publications and Presentations

Climate change will affect various sectors of water resources in Oregon in the 21st century. The observed trends in streamflow show significant declines in September flow and, although not significant, increases in March flow in many transient rain-snow basins. These streamflow trends are associated with rising temperature and coincident declines in snowpack in spring in the latter half of the 20th century. While there are no distinct trends in high precipitation events, such events are associated with climate variability such as ENSO and PDO. Effects of ENSO and PDO are more pronounced at the beginning and end of the wet …

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.

This project was conducted under the supervision of Sumner Sharpe and Ellen Bassett.

Symbolic Structures As Systems: On The Near Isomorphism Of Two Religious Symbols, Martin Zwick

Complex Systems Faculty Publications and Presentations

Many symbolic structures used in religious and philosophical traditions are composed of “elements” and relations between elements. Similarities between such structures can be described using the systems theoretic idea of “isomorphism.” This paper demonstrates the existence of a near isomorphism between two symbolic structures: the Diagram of the Supreme Pole of Song Neo-Confucianism and the Kabbalistic Tree of medieval Jewish mysticism. The similarities of these two symbols in form and meaning are remarkable in the light of the many differences that exist between Chinese and Judaic thought. Intercultural influence might account for these similarities, but there is no historical evidence …

Decision-Making In Secondary And Tertiary Interventions Of School-Wide Systems Of Positive Behavior Support, Terrance M. Scott, Peter J. Alter, Michael Rosenberg, Christopher Borgmeier

Special Education Faculty Publications and Presentations

Although the conceptual foundations of PBS at the universal level have been widely described and presented in the literature, secondary and tertiary interventions have been presented through very limited examples. This paper defines the key features of secondary and tertiary interventions and presents a decision-making process to guide schools through a continuum of strategies at these levels. The continuum is described in terms of a recursive loop, repetitively asking four questions: what is predictable about student failure, what is the simplest effective intervention, how can consistent implementation be achieved, and is it working? With each pass through this set of …

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 …

Home Life: Cultivating A Domestic Aesthetic, Jessica J. Lee

Contemporary Aesthetics (Journal Archive)

Home Life is an exploration of environmental aesthetics as it applies to the domestic realm. I consider Kevin Melchionne’s argument that through notions of taste, grace, and performance, everyday domestic chores can become heightened artistic practices. I argue that this does not go far enough in overcoming the traditional view of art as aesthetically superior to popular or everyday artefacts and practices; rather, it encourages the limitations of traditional aesthetics values within the domestic setting. Through examples, including Pauliina Rautio’s study on laundry, I consider the possibility that domestic practices are made up of actions that are not performed with …

The Curatorial Muse, Michael J. Kowalski

Contemporary Aesthetics (Journal Archive)

An appreciation of the tension between the predicate, "to curate," and the subject, "the curator," is essential to understanding the convergence of creation, criticism, and administration in the graphic arts of our time. Curators were ideally positioned to step to the fore when the idea-versus-object dichotomy began to collapse in the work of Duchamp. The roots of activist curating can be found in Western Classical culture. The prevalence of conceptual art at the end of the twentieth century, combined with the explicit denigration of physical craft by artists, created a void into which activist curators moved. The curator's role as …

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 …

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 …
