Retained Woody Structure In 1-Year-Old Loblolly Pine Plantations In Mississippi, Louisiana, And Arkansas, Justin Neu

Theses and Dissertations

I evaluated effects of 4 common site preparation techniques on residual structure while comparing 2 techniques commonly used to estimate CWD volume in Southeast loblolly pine (Pinus taeda) commercial pine plantations in 2 ecoprovinces. The strip plot method (SPM) estimated greater volume than the line intercept method (LIM; 9.7 m3/ha and 11.4 m3/ha respectively). The SPM had lesser volume estimate variability and appears more appropriate for the Southeast. Mechanical sites had the greatest densities of green trees and fewest snag retention and overall were least decayed. Chemical preparation combinations had lesser green tree densities but greater snag densities. Piled CWD …

Examining The Praxis Ii For Initial Licensure In French, German, And Spanish: Perspectives Of Foreign Language Faculty Members And Teacher Candidates, Kelly Marie Moser

Theses and Dissertations

In compliance with NCLB, states receiving Title I funding were to ensure that all teachers of core subject areas, including foreign languages, were highly qualified by the end of the 2005-2006 academic year. Given that 44 states assess teacher quality through The Praxis Series tests, and 32 of these rely on one of the Praxis II subject-matter tests to gauge foreign language competency (ETS, 2010a), research examining the perspectives of teacher candidates and faculty members regarding these licensure tests is needed. The purposes of this study were to (a) examine the perspectives of teacher candidates and faculty members regarding the …

Human Predation Risk Effects On Adult, Male White-Tailed Deer Antipredator Behavior, Andrew Richard Little

Theses and Dissertations

Recreational hunters play an important role in managing white-tailed deer (Odocoileus virginianus); however, the potential for deer to alter behaviors to avoid hunters has not been addressed within the risk-allocation hypothesis. I evaluated magnitude (i.e., hunter density) and temporal variation (i.e., time of day and initial and prolonged exposure) in human predation risk on movements, resource selection, and observation rates of 37 adult male deer in southern Oklahoma. Deer recognized human predation risk by increasing diel path complexity and use of security cover with greater hunter density. Moreover, deer reduced movement rates and tortuosity while seeking out areas with security …

A new method for estimation of Voltage Stability Load Index (VSLI) for a power system using data from optimally located phasor measurement units (PMU) is presented in this paper. Optimal PMU placement was carried out considering islanding operating conditions. vs.LI is estimated using a kind of recurrent neural network known as the Echo State Network (ESN). the development ESN is computational efficient and provides accurate estimation. Results of optimal PMU placement for normal and islanded operating conditions, and ESN estimation of vs.LI on the IEEE 14 bus system is presented. © 2011 IEEE.

Should Distribution Systems Engineering Be Taught At The Undergraduate Level?, Badrul Chowdhury, Anil Pahwa

Electrical and Computer Engineering Faculty Research & Creative Works

Although there are some exceptions, a distribution systems course is not part of a typical undergraduate curriculum. the course is usually taught at the graduate level. Teaching a distribution systems course requires the student to have a background in balanced three-phase power system modeling such as that obtained from a first power systems analysis course. the requirement to add breadth to an undergraduate curriculum often precludes the notion of depth in any one area unless a student takes the depth courses as technical or free electives. an argument could be made that a distribution systems course does not contain much …

Innovative Smart Grid Control Technologies, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

The smart electric power grid will evolve into a very complex adaptive system under semi-autonomous distributed control. It will be spatially and temporally complex, non-convex, non-linear and non-stationary, with lots of variability and uncertainties beyond what the traditional power system experiences today. the distributed integration of intermittent sources of energy and energy storage to a power grid further adds complexity and challenges to modeling, control and optimization of the grid. Innovative control technologies are needed to handle the growing complexity of a smart grid, maximize the penetration of renewable energy, and provide maximum utilization of available energy storage, especially plug-in …

“The Reputation Of The Queen And Public Opinion: The Case Of Isabeau Of Bavaria”, Tracy Adams, Glenn Rechtschaffen

Medieval Feminist Forum: A Journal of Gender and Sexuality

This essay takes issue with a still common tendency to read contemporary criticisms of powerful women as straightforward evidence of their “unpopularity,” using as a cast study Isabeau of Bavaria (1371-1435), who was generally imagined to have suffered the scorn of her contemporaries. In part one of the essay we argue that the two sources that scholars have relied upon prove not that public opinion turned against Isabeau in 1405-1406, but only that her political enemy Jean of Burgundy was planting negative propaganda about her in hopes of damaging her reputation during those years. In part two we consider whether …

Intelligent Sense-Making For Smart Grid Stability, Ganesh K. Venayagamoorthy

Electrical and Computer Engineering Faculty Research & Creative Works

The power systems of the future - smart grids - will see an increase in both renewable energy sources and load demand, thus increasing the need for fast dynamic reconfiguration of system parameters to handle energy and load dispatches. Power systems will need to be monitored continuously to maintain stability under normal and abnormal operating conditions and when facing disturbances. a combination of system state prediction, dynamic power flow, system optimization, and solution stability checking will allow for a more reliable, affordable, efficient and clean power grid. the optimization and control systems on a smart grid will require a computational …

Polishing Treadmills At Midnight: Is Refugee Integration An Elusive Goal?, Woods Nash

Catalyst: A Social Justice Forum

It is often said that justice requires us to treat like cases alike. Accordingly, the U.S. refugee resettlement program provides all refugees—no matter where they are from, no matter their pasts—with very similar funding and services. Refugees, however, are far from alike. In this essay, I invoke Borgmann’s distinction between a “thing” and a “device” and draw on stories from my work with a resettlement agency to argue that our current, employment-driven system is in need of reform. Instead of being restricted to generic programs, refugee resettlement agencies should be funded to help each family achieve social integration in ways …

The Garden Is Always Greener..., Billy Hall

Catalyst: A Social Justice Forum

This essay builds upon a case study of community gardening in Miami to explore the extent to which these gardens are contributing to, and possibly triggering, processes of gentrification within low to lower-middle income neighborhoods. Through a literature review of recent urban planning policy and development in Miami and relevant discourse on the neoliberalization of food, food politics, food justice activism, and gentrification, I situate Miami’s gardens within a complex, multi-scalar web of ideas and processes. I show how the interaction of these forces, varying dramatically with respect to place, is implicit in the motivations for each garden’s development and …

The Sound Of Fury: Teaching, Tempers, And White Privileged Resistance, Tema J. Okun

Catalyst: A Social Justice Forum

This essay focuses on the resistance of students situated in positions of privilege in classrooms addressing issues of dominance, identity, and oppression related to race and racism. Examining the psycho/social history of two critical aspects of resistance – defensiveness (related to guilt and shame) and denial – the author draws from both practice and theory to explicate the roots of this resistance and offer specific, effective ways to support students in moving through resistance into responsibility.

Educating For Peace And Justice In America's Nuclear Age, Ian Harris, Charles F. Howlett

Catalyst: A Social Justice Forum

The emergence of peace education as embodied in the context of peace studies, which emerged during the post-World War II ideological struggle between capitalism and Communism, the nuclear arms race pitting the United States against the former Soviet Union, the Vietnam War, and the civil rights movement in America, met with considerable criticism. There were many within and outside the academic community who argued that peace studies had very little to offer in terms of “real scholarship” and were primarily politically motivated. Some went so far as to insist that this new area of study lacked focus and discipline given …

Pushing Me Through: A Poetic Representation, Jessica Nina Lester, Rachael Gabriel

Catalyst: A Social Justice Forum

For many children and adults labeled learning disabled (LD), the very process of being identified and eventually labeled is oriented to as difficult to understand, disorienting, and just a taken-for-granted part of a system that names some ‘normal’, even gifted, while others are named abnormal. Minimal research exists that attends to the ways in which the official ways of talking about LDs are worked up in the everyday language of those most involved in the special education process, particularly the students themselves. Thus, in this article, we present, in an alternative form of writing (Richardson, 1997), a poetic representation of …
