Dancing Through Film Musicals: Narratives In Motion, Dara Phillips Dec 2006

Dancing Through Film Musicals: Narratives In Motion, Dara Phillips

Masters Theses

The purpose of this study was to discover if and how dance communicates vital plot and character information nonverbally. The example analyzed was the film Singin’ in the Rain. This thesis examined the six dance sequences in the film to determine if the dancing is an integral, powerful, and significant communicative addition to the film. Walter Fisher’s Narrative Paradigm was used in conjunction with Seymour Chatman’s concept of kernels and satellites to determine if the dances communicated significantly to the film’s viewers. The Narrative Paradigm, though loosely framed, provided the concepts of coherence and fidelity. These concepts ...


Tic: Term Intersection Clustering Of Text Documents, Casey R. Bartman Dec 2006

Tic: Term Intersection Clustering Of Text Documents, Casey R. Bartman

Masters Theses

Preliminary work performed by the author [3] investigated the clustering of text documents based upon the Boolean intersection of document term sets. In that algorithm, documents were associated with terms and the resulting sets of terms were intersected. If the intersection of the sets produced a set equal to or larger than a predefined minimum support level, that new set was considered a relevant cluster. The algorithm’s first intersections were carried out at a three term level, allowing overlap of clusters at this level. Documents that were clustered were removed from further consideration and the process repeated at the ...

The Environmental Reward Observation Scale (Eros): Development, Validity, And Reliability, Maria Elizabeth Anne Armento Dec 2006

The Environmental Reward Observation Scale (Eros): Development, Validity, And Reliability, Maria Elizabeth Anne Armento

Masters Theses

Researchers have established a strong association between the frequency and duration of environmental reward and affective mood states, particularly in relation to the etiology, assessment and treatment of depression. Given behavioral theories that outline environmental reward as a strong mediator of affect and the unavailability of an efficient, reliable and valid self-report measure of environmental reward, we developed the Environmental Reward Observation Scale (EROS) and examined its psychometric properties. In Experiment one, an exploratory factor analysis supported a unidimensional 10-item measure with strong internal consistency and test-retest reliability. When administered to a replication sample, confirmatory factor analysis suggested an excellent ...

Fields With Dreams: The Distribution Of Farmland With Publicly-Funded Conservation Easements In Pennsylvania, Amy Sue Hill Dec 2006

Fields With Dreams: The Distribution Of Farmland With Publicly-Funded Conservation Easements In Pennsylvania, Amy Sue Hill

Masters Theses

Conservation easements have played an increasingly significant role in the American movement to preserve farmland from urban development. Conservation easements are legal instruments that enable a landowner to sell his right to develop his property to an outside party, typically a government entity or a private land conservancy. The distribution of conservation easements used to preserve farmland is highly variable. Conservation easements often are found in regions where productive farmland and intense development pressure collide. Conservation easements are most common in places where both public and private sectors give strong financial and political support for conservation.

This thesis analyzes the ...

Debating Development Help: Ngo Fieldworker Perspectives On Street And Urban Poor Children In Ghana, Richard D. Darby Dec 2006

Debating Development Help: Ngo Fieldworker Perspectives On Street And Urban Poor Children In Ghana, Richard D. Darby

Masters Theses

This ethnographic investigation of the non-governmental organization (NGO) Catholic Action for Street Children (CAS) questions the cultural appropriateness of its policies and practices. By situating CAS in a historical context of colonialism and structural adjustment reforms, I show how it is responsive to a legitimating environment that consists of private donors, international finance institutions, and the Ghanaian government, all of which put pressure on CAS to specifically target "street children" and to adopt a policy of choice that places primary responsibility for development on the individual child. I argue that the legitimating environment is neoliberal in orientation, especially with respect ...

Evaluation Of Socioeconomic Characteristics Of Farmers Who Choose To Adopt A New Type Of Cropand Factors That Influence The Decision To Adopt Switchgrass For Energy Production, Pamela C. Ellis Dec 2006

Evaluation Of Socioeconomic Characteristics Of Farmers Who Choose To Adopt A New Type Of Cropand Factors That Influence The Decision To Adopt Switchgrass For Energy Production, Pamela C. Ellis

Masters Theses

Evaluating farmers’ perceptions and obtaining feedback about the adoption of a new crop is necessary for improving the efficiency of research, technology exchange, and information flow to policymakers. New technology has created new uses for non- traditional crops (such as switchgrass) as a sustainable source of energy. With new technology utilizing non-traditional crop uses, it is important to discern and understand the determinants of farmers’ behavior and attitudes toward new crop adoption rather than new technology adoption. Farmers must analyze financial and social costs and benefits of new crops, farming practices, and economic activities. Better understanding of the factors farmers ...

Multiple Resolution Nonparametric Classifiers, David Laurence Beck Dec 2006

Multiple Resolution Nonparametric Classifiers, David Laurence Beck

Masters Theses

Bayesian discriminant functions provide optimal classification decision boundaries in the sense of minimizing the average error rate. An operational assumption is that the probability density functions for the individual classes are either known a priori or can be estimated from the data through the use of estimating techniques. The use of Parzen- windows is a popular and theoretically sound choice for such estimation. However, while the minimal average error rate can be achieved when combining Bayes Rule with Parzen-window density estimation, the latter is computationally costly to the point where it may lead to unacceptable run-time performance. We present the ...

A Reconfigurable Supercomputing Library For Accelerated Parallel Lagged-Fibonacci Pseudorandom Number Generation, Yu Bi

Masters Theses

To help promote more widespread adoption of hardware acceleration in parallel scientific computing, we present portable, flexible design components for pseudorandom number generation. Due to the success of the Scalable Parallel Random Number Generators (SPRNG) software library in stochastic computations (e.g., Monte Carlo simulations), we developed an efficient and portable hardware architecture fully compatible with SPRNG’s Parallel Additive Lagged Fibonacci Generator (PALFG). Our general design produces identical results for all the parameter sets that SPRNG supports and yields high performance parallel random number generators which can each generate 162 million 31-bit uniform random integers per second on Xilinx ...


The Effects Of Pathogen Infection On Nitrogen Remobilization In Arabidopsis Thaliana, Michelle Ann Boercker Dec 2006

The Effects Of Pathogen Infection On Nitrogen Remobilization In Arabidopsis Thaliana, Michelle Ann Boercker

Masters Theses

The natural enemies of plants are ubiquitous and can reduce plant fitness. Plants have evolved two defense strategies to ameliorate the fitness cost associated with natural enemy attack. The first strategy, resistance, reduces the frequency and/or severity of natural enemy damage. The second strategy, tolerance, attenuates the fitness cost of natural enemy damage. Very little is known about the traits through which tolerance is manifested, particularly with respect to plant-pathogen systems (pathosystems). Diseased and naturally senescing leaves are often similar in their visible symptoms and molecular activities, suggesting that they may involve similar processes. One process that may be ...
