Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry Jan 2003

Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry

LSU Doctoral Dissertations

Physical inactivity is a major health risk factor in our society. Women and minority populations are especially at risk with regard to physical inactivity. This three-part study employed quantitative and qualitative methodologies to investigate physical activity behaviors in middle aged and older African American women. This population was chosen because African American women are the least active segment of our society. In the first phase, a quantitative approach was used to investigate relationships between Self-Determination and the Stage of Change for physical activity in a sample of 105 African American women. This study provided validation for using this theoretical approach …

The Transcendental Eigenvalue Problem And Its Application In System Identification, Kumar Vikram Singh Jan 2003

The Transcendental Eigenvalue Problem And Its Application In System Identification, Kumar Vikram Singh

LSU Doctoral Dissertations

An accurate mathematical model is needed to solve direct and inverse problems related to engineering analysis and design. Inverse problems of identifying the physical parameters of a non-uniform continuous system based on the spectral data are still unsolved. Traditional methods, for the system identification purpose, describe the continuous structure by a certain discrete model. In dynamic analysis, finite element or finite difference approximation methods are frequently used and they lead to an algebraic eigenvalue problem. The characteristic equation associated with the algebraic eigenvalue problem is a polynomial. Whereas, the spectral characteristic of a continuous system is represented by certain transcendental …

Sustainable Agriculture And The Red Stick Farmers' Market: An Exploration Of The Use Of Concept In Design, Lawrence Christopher Campany Jan 2003

Sustainable Agriculture And The Red Stick Farmers' Market: An Exploration Of The Use Of Concept In Design, Lawrence Christopher Campany

LSU Master's Theses

This is a treatise on an attempt to translate a concept -- the driving principle of a design in the parlance of the design studios at the Louisiana State University School of Landscape Architecture -- into practice, form and function. If form follows function, as states the oft quoted proverb of design credited to Louis Sullivan, then perhaps as much attention should be given to the design of the function as the form. What this treatise will demonstrate is that function designed around a concept can result in physical manifestations, or forms, of that concept. In this case a concept …

The Relationship Between Elementary School Foreign Language Study In Grades Three Through Five And Academic Achievement On The Iowa Tests Of Basic Skills (Itbs) And The Fourth-Grade Louisiana Educational Assessment Program For The 21st Century (Leap 21) Test, Carolyn Joyce Taylor-Ward

LSU Doctoral Dissertations

The passage of the federal educational legislation, No Child Left Behind Act of 2001, established foreign languages as a core curricular content area. Nonetheless, educational policy makers at the state and local levels often opt to allocate greater resources and give instructional priority to content areas in which students, and ultimately the school systems themselves, are held accountable through high-stakes testing. Although foreign languages are designated as a core content area, instructional emphasis continues to be placed on curricular areas that factor into state educational accountability programs. The present study employed a mixed-methodology design. The primary goal was to explore …

The Institutional Determinants Of Property Regime Change In New Democracies: The Russian Federation, Hungary, And Czechoslovakia, R. Vanessa Krasner Jan 2003

The Institutional Determinants Of Property Regime Change In New Democracies: The Russian Federation, Hungary, And Czechoslovakia, R. Vanessa Krasner

LSU Doctoral Dissertations

Is there a relationship between the design of democratic institutions and optimal collective decisions? Optimum decisions are defined as achieving goals important to the transition such as deep and equitable property reforms. Democratic institutions refer to first-order institutions of governance and the electoral rules for choosing leaders. Overseeing both are the written or "parchment" constitutions. Constitutions are designed to distribute power among actors, generate efficiency, and govern the interactions among actors. My findings showed that constitutional designs intentionally and sometimes with unanticipated consequences can result in highly cooperative, competitive, or conflictual struggles by political actors over high-stakes distributive issues such …
