Extending The Reach Of Educational Research: Applying Product Commercialization Processes To Communities Of Practice, Richard Edward Culatta Mar 2007

Extending The Reach Of Educational Research: Applying Product Commercialization Processes To Communities Of Practice, Richard Edward Culatta

Theses and Dissertations

The ability to extend educational research beyond the research community could have a great impact on end-users such as teachers, students, or educational administrators. One way to extend the use of educational research is to create tangible educational products; such as virtual simulations, instructional videos, and printed materials; which can be easily and widely distributed. In order to transform research into products, members of the research community must adopt and implement certain product commercialization processes. Effective processes, if not recognized by members of the community, are not helpful for ensuring that quality end products are reached. Likewise, a supportive community …

Filming Theater: The Audiovisual Documentation As A Substitute Of The Performance, Nestor Fernando Bravo Mar 2007

Filming Theater: The Audiovisual Documentation As A Substitute Of The Performance, Nestor Fernando Bravo

Theses and Dissertations

Theatre is not a thermometer of society; it is the fever. The archive is the aftermath that recalls that fever. In this thesis I theorize about the status of audiovisual documentation, its functionality, and its ontological relation with the performance. I argue that the film of a performance does not constitute evidence per se, but it acquires such status through the concurrence of other documents and archival artifacts existentially related to the theatrical production. I also propose that the audiovisual document becomes a substitute for the performance when it has disappeared from the historical world, becoming the new referent for …

On-The-Fly Dynamic Dead Variable Analysis, Joel P. Self Mar 2007

On-The-Fly Dynamic Dead Variable Analysis, Joel P. Self

Theses and Dissertations

State explosion in model checking continues to be the primary obstacle to widespread use of software model checking. The large input ranges of variables used in software is the main cause of state explosion. As software grows in size and complexity the problem only becomes worse. As such, model checking research into data abstraction as a way of mitigating state explosion has become more and more important. Data abstractions aim to reduce the effect of large input ranges. This work focuses on a static program analysis technique called dead variable analysis. The goal of dead variable analysis is to discover …

Legislation, Litigation, Regulation, And Implementation Of Paraprofessional Supervision In School Settings, Sungti Hsu

Theses and Dissertations

Since the reauthorization of the No Child Left Behind Act (NCLB) of 2002 and the Individuals with Disabilities Education Improvement Act (IDEIA) of 2004, there is a strong emphasis on the supervision of paraprofessionals who provide instructional assistance to classroom teachers. Scholars have stressed and litigation has highlighted the importance of paraprofessional supervision. However, there is limited information regarding the definition of supervision, who should and how that supervision should happen. The NCLB and IDEIA legislation leaves room for states to establish state regulation and litigation to interpret supervision. This study explored the current litigation and scholarly works concerning how …

The Role Of Stat And The Jak/Stat Pathway In Mediating The Effects Of Interleukin-6 On Star Expression, Janae Strickland Mar 2007

The Role Of Stat And The Jak/Stat Pathway In Mediating The Effects Of Interleukin-6 On Star Expression, Janae Strickland

Theses and Dissertations

Cortisol, a hormone produced by a hormone produced by the adrenal gland, is responsible for many regulatory functions in the body. Cortisol release is mediated by adrenocorticotrophic hormone, or ACTH, through the hypothalamus-pituitary-adrenal or HPA axis. This HPA axis is the major release pathway used during acute stress, during which the levels of ACTH parallel those of cortisol. However, in states of chronic stress, the level of ACTH drops dramatically, while cortisol remains high. This study focuses on the pathway of cortisol release during these chronic stress states, specifically examining the role of IL-6 with respect to STATs and the …

To Take Posesion Of The Crown: Forms, Themes, And Politics In Julia Palmer's Centuries, Brittany Beahm Mar 2007

To Take Posesion Of The Crown: Forms, Themes, And Politics In Julia Palmer's Centuries, Brittany Beahm

Theses and Dissertations

Julia Palmer, a little-known religious poet, composed two centuries-collections of one hundred poems intended to be sung as hymns-in the two years between 1671 and 1673. Palmer's manuscript is unique in that its author was perhaps the only self-taught Nonconformist woman to have composed centuries during the Restoration period. Although religion shaped the lives of most British citizens at the time, the public literary expression of spiritual experiences-particularly by middle-class women-was uncommon within conventional Puritanism. The poetry's hybrid of forms, proliferation of religious themes, and undertones of political subversion offer an important glimpse into the way Puritan women writers of …

Rethinking Trümmerliteratur: The Aesthetics Of Destruction Ruins, Ruination, And Ruined Language In The Works Of Böll Grass, And Celan, Kurt R. Buhanan Mar 2007

Rethinking Trümmerliteratur: The Aesthetics Of Destruction Ruins, Ruination, And Ruined Language In The Works Of Böll Grass, And Celan, Kurt R. Buhanan

Theses and Dissertations

Trümmerliteratur - literally “rubble-literature" - is a brand of literature that became important after the Second World War, led by Heinrich Böll, whom I term the apologist of German Trümmerliteratur. Typically included under this classification are the writers who began to produce in the years immediately following the war, and in whose work the rubble and ruins of the landscape figure prominently. Böll provided the programmatic framework for the movement in his “Bekenntnis zur Trümmerliteratur" but his relationship to another type of ruin writing presents a point of friction when he appears to be working in a romantic mode to …

An Evaluation Of American Companies That Outsource Manufacturing To China: Decision-Making And Performance, Michael Kenyon Favreau Mar 2007

An Evaluation Of American Companies That Outsource Manufacturing To China: Decision-Making And Performance, Michael Kenyon Favreau

Theses and Dissertations

The topic of outsourcing ranks at the top of business issues for a wide variety of companies (Wery, 2004; Ezrati, 2004). The majority of American companies believe that offshore-related matters rank as the most strategic decisions that management is expected to make in the next 12 months (Wery, 2004). “Outsourcing in China can help many companies save money, but it can be very frustrating if not done right" (Ting, 2004). The perceived benefits of outsourcing production to China are tremendously enticing, but a lack of understanding of the total costs involved lures many companies into outsourcing when it is not …

Rectification Of 2-D To 3-D Finite Element Analysis In Buried Concrete Arches Under Discrete Loading, Adam D. Aagard Mar 2007

Rectification Of 2-D To 3-D Finite Element Analysis In Buried Concrete Arches Under Discrete Loading, Adam D. Aagard

Theses and Dissertations

Construction of tunnels and small- to medium-span bridges is a $12 billion per year industry in the United States, with a significant portion going into buried arch structures. Notwithstanding such expenditure, modern arch design and construction, in many cases, is highly conservative. This is because the closed-form solutions used by most designers today do not correctly account for soil-structure interaction. In fact, soil-structure interaction makes a closed form solution impossible. With the advent of high power computers in recent years, some designers have turned to finite element (FE)modeling as the main vehicle of analysis. Such numerical procedures provide an accurate …

The Effects Of Vortex Generator Jet Frequency, Duty Cycle, And Phase On Separation Bubble Dynamics, Matthew J. Bloxham Mar 2007

The Effects Of Vortex Generator Jet Frequency, Duty Cycle, And Phase On Separation Bubble Dynamics, Matthew J. Bloxham

Theses and Dissertations

Vortex generator jets (VGJs) have proven to be effective in minimizing the separation losses on low-pressure turbine blades at low Reynolds numbers. Experimental data collected using phase-locked particle image velocimetry and substantiated with a hot-film anemometer were used to answer fundamental questions about the influence of VGJs on a separated boundary layer. The data were collected on the suction surface of the Pack B blade profile, which has a non-reattaching separation bubble beginning at 68% axial chord. Two VGJ pulse histories were created with different frequencies, jet durations, and duty cycles. The mechanisms responsible for boundary layer separation control were …
