Characterization Of Kraft Alkali Lignin And Products Of Its Thermal Degradation By Fractional Pyrolysis Methods, Keith Michael Voeller

Theses and Dissertations

At present, methods addressing the characterization of lignin and its decomposition products are limited. Typical approaches reported various spectroscopic, chromatographic and thermal methods. None of the methods is ideal for different reasons. In this study, a novel thermal carbon analysis (TCA) was developed providing essential mass balance data complementary to liquid-liquid extraction (LLE) prior to separation and identification by gas chromatography and mass spectrometry (GC-MS) as well as thermal desorption-pyrolysis-gas chromatography-mass spectrometry (TD-Py-GC-MS) to fully characterize lignin and its degradation products from hydrothermal treatment in subcritical water conditions.

The TCA method enabled a quantitative thermal evolution profile through TD and …

How Shared Experiences Impact Teachers Who Remain In American Indian Elementary Schools More Than Five Years, Rae Marie Wilkie-Villebrun

Theses and Dissertations

This qualitative study examined shared experiences of teachers who remain at American Indian schools teaching for five years or more in an attempt to help administrators understand what factors impact a teacher’s decision to stay. Teachers, regardless of their race or gender, who have worked at an American Indian school for five years or longer, were interviewed. The teachers were recruited to participate in this study through their superintendent/principals and personal contacts. The theoretical framework used to guide this study was a social support model studied by LaRocco, House, and French in 1980. They examined the effect of perceived social …

Hits And Runs: Determinants Of The Cross-Country Variation In The Severity Of Impact From The 2008-09 Financial Crisis, Shane Dwyer, Chih Ming Tan

Economics & Finance Faculty Publications

Recent empirical work on the 2008-09 financial crisis has found mixed results on the usefulness of indicators to explain the cross-country variation in the incidence of the crisis in non-originating countries. While some authors have found success with various indicators, Rose and Spiegel (2009a,b) find that almost no indicators are robust. We employ Bayesian model averaging (BMA) to verify Rose-Spiegel’s conclusions under model uncertainty, confirming their findings. We then employ latent class models (LCM) to check the data for parameter heterogeneity. We find that there is substantial evidence of heterogeneity in the relationship between various indicators and crisis impact, both …

Reproductive Health Education In Nctb Curriculum And Text Books: A Critical Review, Salma Akhter, Shah Shamim Ahmed, Muhammad Salahuddin

Education, Health & Behavior Studies Student Publications

The Education Policy-2010, paved the way to introduce Reproductive Health (RH) as part of curricula of few selected subjects for the secondary school children in Bangladesh, which can be considered as a first step in the right direction. Consequently subjects like Physical Education and Health and Home Science has been chosen to incorporate some aspects of RH for the students of classes VI-VIII, and Science are for the students of classes IX-X. This article aimed to explore, examine and review critically to what extent incorporation has taken place and whether this has fulfilled the learning needs of the adolescent groups …

Privatization Of Air Traffic Control Services In The United States: A Comparison Of Past Government Privatization Efforts In The United States And Other Countries, Daniel Lindsey

Theses and Dissertations

The privatization of air traffic control (ATC) is one possible way to reduce the cost, increase the efficiency, and speed the innovation of ATC in the United States. However, studies from other countries in which ATC services have been privatized show mixed results in these areas and have often involved imposing some kind of fee-for-service pricing system. Furthermore, analyses of privatization efforts in other areas of government demonstrate that such efforts have been controversial and have not always resulted in lower service delivery costs. Therefore, a possible alternative would be to focus on reorganizing the FAA and consolidating services such …

Psychometrics And Test-Enhanced Learning In A Patient-Centered Learning Curriculum, Syed Haris Ali

Theses and Dissertations

Validity and reliability of scores obtained on Multiple-choice questions (MCQs), as well as the benefits of test-enhanced learning, have been of interest to medical educator scholars. Presented in this dissertation are four composite studies on these themes. The following hypotheses were tested:

1. Increased MCQ distractor functioning increases the validity and reliability of obtained scores.

2. Correction of item writing flaws (along with enhancement of tested cognitive level) and replacement or removal of non-functioning distractors equally improves psychometric characteristics of MCQs.

3. Repeated testing via free-response items enhances the retention of knowledge of human anatomy, compared with repeated or once-testing …

The Relationship Between Labor Unions And Safety In Us Airlines: Is There A "Union Effect?", Renee Catherine Zapf

Theses and Dissertations

Every airline union claims to work for safety and presents anecdotes where greater airline safety has been achieved through union efforts. The effect unionization has on safety outcomes in U.S. commercial airlines, however, wasn’t found to be previously tested. Studies have shown that in industries such as coal mining, retail, and construction, unionization does lead to an increase in safety. This study evaluated the safety rates of 15 major US commercial airlines to compare the difference between unionized and non- unionized airlines. These safety rates were compared based on if and how long each airline’s pilots and flight attendants have …

Bedside Reporting, Melanie Krentz

Theses and Dissertations

Some might say that the complexity of health care as we know it exceeds the capacity of \ .). the human mind. As a result, the process of communication within health care organizations is equally as complex and to a large degree, challenging. Specifically, the patent handoff is particularly problematic and may be defined as " the process of transferring care and accountability for a patient from one health care professional to another'' (Jukkala, James, Autrey, Azuero, & Miltner, 2012, p.240). The aim of this paper is to introduce the notion of bedside reporting after identifying the importance and ongoing …

Orientalism And "Authentic Homosexual": How "The Closet" Reinforces Hegemonic Knowledge And Binary Logic, Contributing To The Invisibility Of Non-Conforming Gender And Sexual Identities, Michelle Bonapace-Potvin

Theses and Dissertations

The critique of Orientalism's binary logic finds a complementary analysis in the questioning of static sexual and gender categories. There is already significant research that points to these intersectional critiques—for instance, Joseph Massad's Desiring Arabs and Jasbir K. Puar’s Terrorist Assemblages: Homonationalism in Queer Times. In this paper, I will use analyses of Orientalism to review the ways in which hegemonic knowledge and binary logic contribute to the invisibility of non- conforming gender and sexual identities. In other words, I will use the language and lens of critiques of Orientalism to observe, analyze, and comment on the current politics of …
