Characterization of Novel Solvents and Absorbents for Chemical Separations (open access)

Characterization of Novel Solvents and Absorbents for Chemical Separations

Predictive methods have been employed to characterize chemical separation mediums including solvents and absorbents. These studies included creating Abraham solvation parameter models for room-temperature ionic liquids (RTILs) utilizing novel ion-specific and group contribution methodologies, polydimethyl siloxane (PDMS) utilizing standard methodology, and the micelles cetyltrimethylammonium bromide (CTAB) and sodium dodecylsulfate (SDS) utilizing a combined experimental setup methodology with indicator variables. These predictive models allows for the characterization of both standard and new chemicals for use in chemical separations including gas chromatography (GC), solid phase microextraction (SPME), and micellar electrokinetic chromatography (MEKC). Gas-to-RTIL and water-to-RTIL predictive models were created with a standard deviation of 0.112 and 0.139 log units, respectively, for the ion-specific model and with a standard deviation of 0.155 and 0.177 log units, respectively, for the group contribution fragment method. Enthalpy of solvation for solutes dissolved into ionic liquids predictive models were created with ion-specific coefficients to within standard deviations of 1.7 kJ/mol. These models allow for the characterization of studied ionic liquids as well as prediction of solute-solvent properties of previously unstudied ionic liquids. Predictive models were created for the logarithm of solute's gas-to-fiber sorption and water-to-fiber sorption coefficient for polydimethyl siloxane for wet and dry conditions. These models …

Unmaking Progress: Individual and Social Teleology in Victorian Children's Fiction (open access)

Unmaking Progress: Individual and Social Teleology in Victorian Children's Fiction

This study contrasts four distinct discursive responses to (or even accidental remarks on) the Victorian concept of individual and/or social improvement, or progress, set forth by the preeminent social critics, writers, scientists, and historians of the nineteenth century, such as Thomas Carlyle, John Stuart Mill, Thomas Macaulay Matthew Arnold, Charles Darwin, and Herbert Spencer. This teleological ideal, perhaps the most prevalent ideology of the long nineteenth century, originates with the Protestant Christian ethic during and in the years following the Reformation, whereupon it combines with the Enlightenment notions of rational humanity's boundless potential and Romanticism's fierce individualism to create the Victorian doctrine of progress. My contention remains throughout that four nineteenth-century writers for children and adults subvert the doctrine of individual progress (which contributes to the progress of the race) by chipping away at its metaphysical and narratalogical roots. George MacDonald allows progress only on the condition of total selflessness, including the complete dissolution of one's free will, but defers the hallmarks of making progress indefinitely, due to his apocalyptic Christian vision. Lewis Carroll ridicules the notion of progress by playing with our conceptions of linear time and simple causality, implying as he writes that perhaps there is nothing to …

Faculty Research Productivity at Addis Ababa University (open access)

Faculty Research Productivity at Addis Ababa University

This study explores the research productivity of Addis Ababa University (AAU) faculty. AAU was established in 1950 and is the oldest modern higher educational institution in Ethiopia. Recently AAU took steps to transform itself to become a pre-eminent African research university. One of the characteristics of a research university is the focus on the amount of research conducted by the institution's faculty. Academic institutions measure research productivity primarily based on published work. The purpose of this study was to analyze the research productivity of AAU faculty, and to examine the differential predictive effects of individual and environmental variables on faculty research productivity. This quantitative study used a theoretical framework and instrument, Faculty at Work. Four hundred questionnaires were distributed to Addis AAU faculty in person and 298 questionnaires were returned resulting in a 74.5% response rate. After exclusion of 12 cases with missing information, 286 cases (71.5% response rate) were analyzed. Most of the respondents were men (M = 92.1%, F = 7.9%). The average age of AAU faculty was 44. A hierarchical multiple regression was used to examine the ability of six sets of independent variables (sociodemographic, career, self-knowledge, social knowledge, behavior, and environmental response) to predict research productivity …

Sheltered Instruction: A Case Study of Three High School English Teachers' Experiences with the SIOP Model

The purpose of this study was to determine the current status of secondary teachers' implementation of the sheltered instruction operational protocol (SIOP) model and its effect on Hispanic English language learners' (ELL) English language proficiency and academic achievement. In addition, this study sought to determine whether teachers perceive the SIOP model as an effective tool for instruction of high school ELL students to increase English language content and English language proficiency. This study employed qualitative and quantitative methodologies. Data were collected from four sources: Hispanic ELLs' English language proficiency scores, students' English Language Arts scores, an oral interview with participating teachers and teacher observations. Each teacher was observed at four points during the school year with the SIOP instrument. Quantitative data on student achievement were collected employing a pre-experimental, one-group pretest-post-test design. Qualitative data were collected using a time-series design. Findings revealed that on the two student assessment measures there were increases in English proficiency and English language arts achievement among the Hispanic ELLs. On the assessment of English language proficiency, the students of the teacher with the highest level of SIOP implementation made the highest gains; the students of the teacher with the second highest SIOP implementation level made …

Recommended Modified zone Method Correction Factor for Determining R-values of Cold-Formed Steel Wall Assemblies (open access)

Recommended Modified zone Method Correction Factor for Determining R-values of Cold-Formed Steel Wall Assemblies

Currently, ASHRAE has determined the zone method and modified zone method are appropriate calculation methods for materials with a high difference in conductivity, such as cold-formed steel (CFS) walls. Because there is currently no standard U-Factor calculation method for CFS walls, designers and code officials alike tend to resort to the zone method. However, the zone method is restricted to larger span assemblies because the zone factor coefficient is 2.0. This tends to overestimate the amount of surface area influenced by CFS. The modified zone method is restricted to C-shaped stud, clear wall assemblies with framing factors between 9 and 15%. The objective of the research is to narrow the gap of knowledge by re-examining the modified zone method in order to more accurately determine R-Values and U-Factors for CFS wall assemblies with whole wall framing factor percentages of 22% and above.

Spatial Ability, Motivation, and Attitude of Students as Related to Science Achievement

Understanding student achievement in science is important as there is an increasing reliance of the U.S. economy on math, science, and technology-related fields despite the declining number of youth seeking college degrees and careers in math and science. A series of structural equation models were tested using the scores from a statewide science exam for 276 students from a suburban north Texas public school district at the end of their 5th grade year and the latent variables of spatial ability, motivation to learn science and science-related attitude. Spatial ability was tested as a mediating variable on motivation and attitude; however, while spatial ability had statistically significant regression coefficients with motivation and attitude, spatial ability was found to be the sole statistically significant predictor of science achievement for these students explaining 23.1% of the variance in science scores.

Jacques-Antoine-Hippolyte, comte de Guibert: Father of the Grande Armée

The eighteenth century was a time of intense upheaval in France. The death of Louis XIV in 1715 and the subsequent reign of Louis XV saw the end of French political and martial hegemony on the continent. While French culture and language remained dominant in Europe, Louis XV's disinterested rule and military stagnation led to the disastrous defeat of the French army at the hands of Frederick the Great of Prussia in the Seven Years War (1756-1763). The battle of Rossbach marked the nadir of the French army in the Seven Years War. Frederick's army routed the French infantry that had bumbled its way into massed Prussian cavalry. Following the war, two reformist elements emerged in the army. Reformers within the government, chiefly Etienne François, duc de Choiseul, sought to rectify the army's poor performance and reconstitute France's military establishment. Outside the traditional army structure, military thinkers looked to military theory to reinvigorate the army from within and without. Foremost among the latter was a young officer named Jacques-Antoine-Hippolyte de Guibert, whose 1772 Essai général de tactique quickly became the most celebrated work of theory in European military circles. The Essai provided a new military constitution for France, proposing wholesale …

The Relationship Between Supplemental Instruction Leader Learning Style and Study Session Design

The purpose of this qualitative study was to examine the learning styles of supplemental instruction leaders at a large, public university during the fall 2010 semester and determine whether or not their personal learning styles influenced the way they designed and developed out-of-class study sessions. The total population of supplemental instruction leaders was 37, of which 24 were eligible to participate in the study. Of the 24 eligible supplemental instruction leaders, 20 completed the entire study. Participants in the study included nine male and 11 female supplemental instruction leaders with a median age of 22.25 years-old. Seventeen participants indicated their classification as senior, two as junior, and one as sophomore. Of the participants, 16 indicated white as a race or ethnicity, one indicated Asian, two indicated African American, and one indicated both American Indian/Alaska Native and white. Supplemental instruction leader learning style was assessed using the Kolb Learning Style Inventory. Leaders were then interviewed, and their study sessions were analyzed. Through triangulation of data from learning style, interviews and actual study session documents, four major themes emerged. The four themes were: 1) incorporation of personal experience into study session design, 2) the sense of impact on student learning, 3) a …

Solvent Effects and Bioconcentration Patterns of Antimicrobial Compounds in Wetland Plants

This study looked at effects of organic solvents dimethylsulfoxide, dimethylformamide and acetone at 0.01%, 0.05% and 0.1% concentration on germination and seedling development wetland plants. Even at 0.01% level, all solvents affected some aspect of seed germination or seedling growth. Acetone at 0.01% was least toxic. Root morphological characteristics were most sensitive compared to shoot morphological characteristics. This study also looked at bioconcentration patterns of antimicrobial compounds triclosan, triclocarban and methyl-triclosan in wetland plants exposed to Denton Municipal Waste Water Treatment Plant effluent. Bioconcentration patterns of antimicrobial compounds varied among species within groups as well as within organs of species. The highest triclocarban, triclosan and methyltriclosan concentration were in shoot of N. guadalupensis, root of N. lutea and in shoots of P. nodous respectively.

The Significance of Feudal Law in Thirteenth-Century Law Codes (open access)

The Significance of Feudal Law in Thirteenth-Century Law Codes

Although developments in feudal law in the thirteenth century influenced the legal environment of Europe for centuries, much of past and current historical research of feudalism examines the social system anthropologically but neglects an in-depth analysis of feudal law codes. My research combines the social-anthropological approach with relevant customary codes to demonstrate the importance of feudal law to a thirteenth-century society plagued by war, economic and social instability, and competing powers of the monarchy, judiciary, and religion. The assessment of feudal law within each legal code highlights its prominence as an accepted category of jurisprudence. This thesis provides a new perspective on the influence of feudalism in the thirteenth century, demonstrating the significance of feudal law as a mode of maintaining peace and prolonging land tenure.

Mechanisms of Ordered Gamma Prime Precipitation in Nickel Base Superalloys (open access)

Mechanisms of Ordered Gamma Prime Precipitation in Nickel Base Superalloys

Commercial superalloys like Rene88DT are used in high temperature applications like turbine disk in aircraft jet engines due to their excellent high temperature properties, including strength, ductility, improved fracture toughness, fatigue resistance, enhanced creep and oxidation resistance. Typically this alloy's microstructure has L12-ordered precipitates dispersed in disordered face-centered cubic γ matrix. A typical industrially relevant heat-treatment often leads to the formation of multiple size ranges of γ¢ precipitates presumably arising from multiple nucleation bursts during the continuous cooling process. The morphology and distribution of these γ′ precipitates inside γ matrix influences the mechanical properties of these materials. Therefore, the study of thermodynamic and kinetic factors influencing the evolution of these precipitates and subsequent effects is both relevant for commercial applications as well as for a fundamental understanding of the underlying phase transformations. The present research is primarily focused on understanding the mechanism of formation of different generations of γ′ precipitates during continuous cooling by coupling scanning electron microscopy (SEM), energy filtered TEM and atom probe tomography (APT). In addition, the phase transformations leading to nucleation of γ′ phase has been a topic of controversy for decades. The present work, for the first time, gives a novel insight into the mechanism …

Portrait of a southern Progressive: The political life and times of Governor Pat M. Neff of Texas, 1871-1952

Pat M. Neff was a product of his political place and time. Born in Texas in 1871, during Reconstruction, he matured and prospered while his native state did the same as it transitioned from Old South to New South. Neff spent most of his life in Waco, a town that combined New South Progressivism with religious conservatism. This duality was reflected in Neff's own personality. On moral or religious issues, he was conservative. On economic and social issues, he was Progressive. He thus was a typical Southern Progressive who de-emphasized social and political change in favor of economic development. For instance, as governor from 1921 to 1925, his work to develop and conserve Texas' water resources brought urbanization and industrialization that made the New South a reality in the state. Neff was a devout Baptist which influenced his politics and philosophy. He was president of Baylor University, a Baptist institution, for fifteen years after leaving the governor s office and he led the Southern Baptist Convention (SBC) in the 1940s. He combined Progressive and Christian values as he argued for the establishment of the United Nations and advocated forgiveness and brotherhood after World War II. The war's end marked the …

Mosques in France: The Visible Presence of Islam

Numerous laws are being directed toward subduing the visible presence of Islam throughout France, and in return French Muslims are becoming bolder in the projection of their faith. This thesis examines the presence of Islam in France throughout history and in contemporary French civilization. Specifically, this thesis addresses the issues regarding the visible presence of Islam in France through such institutions as mosques and how they are the key symbols representing the prominence of Islam in France. It looks at what lies in the collective French mind that creates such an influence on today's policies and outlook, as well as identifies the key characters that dominate the current affairs surrounding Islam in France. The thesis reviews the country's past relations with the visible presence of Islam through the controversies surrounding the construction of famous mosques. In addition, this thesis underlines key areas where both the State and the Muslim population must make concessions in order to avoid further conflict.

Miscegenated Narration: The Effects of Interracialism in Women's Popular Sentimental Romances from the Civil War Years

Critical work on popular American women's fiction still has not reckoned adequately with the themes of interracialism present in these novels and with interracialism's bearing on the sentimental. This thesis considers an often overlooked body of women's popular sentimental fiction, published from 1860-1865, which is interested in themes of interracial romance or reproduction, in order to provide a fuller picture of the impact that the intersection of interracialism and sentimentalism has had on American identity. By examining the literary strategy of "miscegenated narration," or the heteroglossic cacophony of narrative voices and ideological viewpoints that interracialism produces in a narrative, I argue that the hegemonic ideologies of the sentimental romance are both "deterritorialized" and "reterritorialized," a conflicted impulse that characterizes both nineteenth-century sentimental, interracial romances and the broader project of critiquing the dominant national narrative that these novels undertake.

Re-Branding Palliative Care: Assessing Effects of a Name Change on Physician Communicative Processes During Referrals

Although provision of palliative care on the United States is growing, referrals to the service are often late or non-existent. The simultaneous care model provides a blueprint for the most progressive form of palliative care, which is palliation and disease-oriented treatments delivered concurrently. Research indicates the existence of a widespread misconception that associates palliative care with imminent death, and some organizations have chosen to re-brand their palliative care services to influence this perception. The goal of this study was to assess the effects of a name change from palliative care to supportive care on the communicative process during referrals to the service.

The M-shell x-ray production cross section for thorium and uranium have been determined for protons of energy 0.4 - 4.0 MeV, helium ions of energy 0.4 - 6.0 MeV, carbon ions of energy 4.5 - 11.3 MeV and oxygen ions of energy 4.5 - 13.5 MeV. The total cross sections and the cross sections for individual x-ray peaks in the spectrum, consisting of the following transitions Mz (M4-N2, M5-N3, M4-N3), Ma (M5-N6,7), Mb (M4-N6, M5-O3, M4- O2), and Mg (M4-O3, M5-P3, M3-N4, M3-N5), were compared to the theoretical values determined from the PWBA + OBKN and ECUSAR. The theoretical values for the carbon and oxygen ions were also modified to take into account the effects of multiple ionizations of the target atom by the heavier ions. It is shown that the results of the ECUSAR theory tend to provide better agreement with the experimental data.

Ion Beam Synthesis of Carbon Assisted Nanosystems in Silicon Based Substrates

The systematic study of the formation of β-SiC formed by low energy carbon ion (C-)implantation into Si followed by high temperature annealing is presented. The research is performed to explore the optimal annealing conditions. The formation of crystalline β-SiC is clearly observed in the sample annealed at 1100 °C for a period of 1 hr. Quantitative analysis is performed in the formation of β-SiC by the process of implantation of different carbon ion fluences of 1×1017, 2×1017, 5×1017, and 8×1017 atoms /cm2 at an ion energy of 65 keV into Si. It is observed that the average size of β-SiC crystals decreased and the amount of β-SiC crystals increased with the increase in the implanted fluences when the samples were annealed at 1100°C for 1 hr. However, it is observed that the amount of β-SiC linearly increased with the implanted fluences up to 5×1017 atoms /cm2. Above this fluence the amount of β-SiC appears to saturate. The stability of graphitic C-C bonds at 1100°C limits the growth of SiC precipitates in the sample implanted at a fluence of 8×1017 atoms /cm2 which results in the saturation behavior of SiC formation in the present study. Secondly, the carbon cluster formation process …

Rapid E-Learning Simulation Training and User Response (open access)

Rapid E-Learning Simulation Training and User Response

A new trend in e-learning development is to have subject matter experts use rapid development tools to create training simulations. This type of training is called rapid e-learning simulation training. Though companies are using rapid development tools to create training quickly and cost effectively, there is little empirical research to indicate whether training created in this manner meets the needs of learners. The purpose of this study was to compare user responses to rapid e-learning simulation training to user responses receiving instructor-led training. The target population for this study was employees of a medium size private company in North America. Employees were divided into two groups and either received instructor-led training (comparison group) or received rapid e-learning simulation training (experimental group). The instrument used to measure user response was an adaptation of the technology acceptance model. Three variables were measured: training satisfaction, perceived ease of use, and perceived usefulness. Though no statistical significance was found between the two groups for training satisfaction and perceived usefulness, perceived ease of use was found to be statistically significant. Overall results fail to demonstrate the superiority of rapid e-learning simulation training over instructor-led training; however, this study indicates that rapid e-learning simulation training may …

A Performance Guide to the Trumpet Repertoire of Jacques Castérède Focusing on Brêves Rencontres and Concertino for Trumpet and Trombone

Jacques Castérède's works for brass are monumental and demand extreme agility from the performers. Many brass players are familiar with the Sonata for Trombone, but Castérède's trumpet repertoire has not been as thoroughly considered. Due to the lack of scholarly works and recordings of Jacques Castérède trumpet repertoire, a study is necessary to aid its performance. The study is based on performance analysis and interviews with the composer. The first chapter provides information on the composer's life. The second and third chapters are performance analysis of Brêves Rencontres and Concertino for Trumpet and Trombone. These two chapters also discuss rehearsal technique and sound concept. The performance guide takes place in chapter 4. This chapter gives specific indications on articulation, range and mute choice.

Effectiveness of Play Therapy on Problem Behaviors of Children with Intellectual Disabilities: A Single Subject Design

A growing disparity between the mental health needs of children and their lack of treatment served as the basis of this study. To address this existent gap, I proposed that child-centered play therapy (CCPT), a holistic treatment that fosters children's emotional, developmental, and social growth would serve as a viable treatment. The purpose of this study was to examine the effect of CCPT on problem behaviors among children identified with an intellectual disability. Specifically, a single case, A-B-A design (N = 2) was used to examine changes in participant's problem behaviors as measured on the Aberrant Behavior Checklist (ABC) across conditions. Trained raters used the ABC to rate participant's problem behaviors 3 times per week during the course of this study. Participants completed 2 weeks of a no-intervention phase, 5 weeks of play therapy 3 times per week, and 2 weeks of a no-intervention maintenance phase. Additionally, participants were administered the Gesell Developmental Observation to assess their maturational age during the baseline and maintenance phases. Parents also completed the ABC during two intervals: baseline phase, and maintenance phase. Analysis of results indicated that problem behaviors decreased for both participants.

Understanding News Media Consumption and Political Attitudes and Behavior in Latin America (open access)

Understanding News Media Consumption and Political Attitudes and Behavior in Latin America

News media consumption is vital to understanding democracy in Latin America. Democracy in the region lacks consolidation that may be encouraged by the ability of news media to shape individuals' political attitudes and behaviors. Yet, we know very little about how citizens of Latin American countries consume news media or how that consumption affects attitudes and behavior. This study offers a region-wide examination of the factors that shape news media consumption and the effects of that consumption on individuals in the region. To explore this topic, I examine survey data from the 2008 Latin American Public Opinion Project in 18 Latin American countries. I argue that news media promote democratic attitudes and political behavior by increasing the symbolic value of democracy and by supplementing those symbols with information that further encourages democratic attitudes and political participation. Additionally, political behavior is not temporally proximate to political behaviors such as voting. This necessitates a mediated path for news media consumption to influence participation through political interest, civil society participation and democratic attitudes. My findings illustrate that each news medium type (TV, radio, newspaper) must be considered separately from each other type. I find that news media consumption has little effect on attitudes. …

Effects of Social Networks and Media on Pro-Environment Behaviors

In this study, pro-environmental behaviors are investigated by studying if one's primary information sources about environmental issues either from their social network or the media influence this behavior. Data was collected from the 2002 Detroit Area Study with a total of 267 respondents. Three indexes were constructed to separately measure all seven pro-environment behavioral items, five conservation behavioral items, and two consumption behavioral items. A complex sample model was utilized in these analyses. Findings suggest that information sources are correlated to self-reported environmental behavior. As predicted, the people whose primary information source was social network were more likely to obtain higher scores on all three separate indexes than those individuals who primarily received information about environmental issues from the media.
