Can These Bones Live? A Collection of Stories
The collection concerns itself with race, gender, masculinity, marginalization, the act of violence as a means of self expression, identity and the performance of identity, love, and loss. The collection also uses historical events-more specifically, events that are central to black culture in Northeast, Ohio- to situate the characters and witness their response to these historical events. I strive to illustrate blackness as both political and fragmented with the characters in my collection. My characters believe that what they are doing-exacting violence, abusing women, disrespecting each other- is somehow the normative; that somehow what it is that they have learned is how they should perform black identity.
Instructional Leadership Responsibilities of Assistant Principals in Large Texas High Schools
The purpose of this study was to determine the extent secondary assistant principals in large Texas high schools demonstrate behaviors consistent with what the literature describes as instructional leadership. Three hundred seventy principals and assistant principals of large Texas high schools participated in this study. The Principal Instructional Management Rating Scale (Hallinger, 1987) was used to quantify instructional leadership in 10 different job functions. The study found that (a) assistant principals perceive themselves as exhibiting instructional leadership behaviors at a high frequency, (b) principals perceive their assistant principals exhibiting instructional leadership behaviors at a high frequency, (c) the perceptions of the principals and assistant principals were similar, and (d) principals and assistant principals reported more engagement in instructional leadership responsibilities and felt more pressured over the last five years under the new accountability and rating requirements of No Child Left Behind and the state assessments. These findings suggested that the administrative roles and responsibilities in high schools should be restructured to allow assistant principals to focus on instructional leadership.
Routine Leisure Activities and Adolescent Marijuana Use: Moderating Effects of Family Structure
How adolescents spend their time is a crucial predictor of their engagement in delinquency. Activities with peers away from direct supervision of adults are of concern as more opportunities and motivation to use marijuana exist in such situations. However, adolescents may vary in their propensity to use marijuana when faced the opportunity. Especially adolescents living with a single parent may have a higher propensity compared to those from two-parent households to use marijuana due to reduced parental monitoring and increased peer attachment. This thesis investigates the moderating effects of family structure on the routine leisure activities and adolescent marijuana use relationship, using data from Monitoring the Future Study 2007, 12th Grade Survey. The results provide partial support for the moderating effects.
Environmental Philosophy and the Ethics of Terraforming Mars: Adding the Voices of Environmental Justice and Ecofeminism to the Ongoing Debate
Questions concerning the ethics of terraforming Mars have received some attention from both philosophers and scientists during recent decades. A variety of theoretical approaches have been supplied by a number of authors, however research pursuant to this thesis has indicated at least two major blindspots in the published literature on the topic. First, a broad category of human considerations involving risks, dangers, and social, political, and economic inequalities that would likely be associated with efforts to terraform Mars have been woefully overlooked in the published literature to date. I attempt to rectify that oversight by employing the interpretive lens of environmental justice to address questions of environmental colonialism, equality in terms of political participation and inclusion in decision making structures, risks associated with technological progressivism, and responses to anthropogenic climate change. Only by including the historically marginalized and politically disenfranchised "voices," of both humans and nonhumans, can any future plan to terraform Mars be deemed ethical, moral or just according to the framework provided by environmental justice. Furthermore, broader political inclusion of this sort conforms to what ecofeminist author Val Plumwood calls the "intentional recognition stance" and provides an avenue through which globally societies can include nonanthropocentric considerations in decision making frameworks both for questions of terraforming Mars and also for a more local, contemporary set of environmental issues. The second blindspot I seek to correct concerns motivations for attempting terraforming on Mars previously inadequately philosophically elaborated in the published discourse. Specifically, the nonanthropocentric considerations postulated in the second chapter by various authors writing about terraforming, and elaborated in third with regard to environmental justice, reach their culmination in an ecofeminist ethic of care, sustainability, reproduction, and healthy growth which I uniquely elaborate based on a metaphorical similarity to the relationship between a gardener and a garden. Although at first …
Female Psychopathy Predictors: Cluster B Traits and Alexithymia
Psychopathy has long been lauded as a premier predictor of negative behavioral outcomes because of its demonstrated associations with violence, antisocial conduct, and institutional maladjustment. Traditional conceptualizations of psychopathy highlight the relatively equal importance placed on personality features (i.e., a grandiose, deceitful interpersonal style and deficits in affective experience) and behavioral elements (i.e., an impulsive and irresponsible lifestyle marked by social deviance) of the syndrome. However, little research to date has investigated psychopathy dimensions in female samples, particularly as they relate to maladaptive behaviors beyond forensic settings. The current study comprehensively examined personality (i.e., Axis II Cluster B traits and alexithymia) and behavioral (i.e., suicide-related behavior and aggression) expressions of psychopathy in a sample of female inpatients recruited from trauma and dual-diagnosis units at a psychiatric hospital in Dallas, Texas. Contrary to expectations, the essential components of psychopathy in female psychiatric patients emphasized APD and NPD traits over features of HPD and BPD, which were relatively similar to elements traditionally highlighted in male psychopathy. On this point, two latent dimensions comprehensively addressed female psychopathy in the current sample: impulsive antisociality and narcissistic and histrionic interpersonal style. Interestingly, psychopathy (M r = .01) and Cluster B traits (M r = .05) were virtually unrelated to suicide-related behavior in female patients with trauma and substance use histories, but APD and BPD traits were more discerning for impulsive and premeditated aggression than variants of psychopathy. Aggression's relationship to BPD traits is at least partially mediated by alexithymia. These results are discussed in terms of improving evaluation and intervention efforts aimed at identifying and managing psychopathic females beyond forensic settings.
The Useful Arts
This creative nonfiction dissertation is a series of braided narratives that chronicle the author's career as a trombonist in the John Smith Ensemble. As an amateur trombonist, the author is shocked to be hired as a professional musician for an orchestra that plays on PBS and at Carnegie Hall. She quickly realizes, however, that the job requires her to play the trombone quietly in front of an unplugged microphone while a CD recording of another, more talented trombonist is blasted out toward an unknowing audience. The job also requires the author to tour around America. The scenes of from this tour are braided with scenes wherein she reflects on her life as a professional fake musician and her past failed attempts at getting a job.
Military-diplomatic Adventurism: Communist China's Foreign Policy in the Early Stage of the Korean War (1950-1951)
The thesis studies the relations of Communist China's foreign policy and its military offensives in the battlefield in Korean Peninsula in late 1950 and early 1951, an important topic that has yet received little academic attention. As original research, this thesis cites extensively from newly declassified Soviet and Chinese archives, as well as American and UN sources. This paper finds that an adventurism dominated the thinking and decision-making of Communist leaders in Beijing and Moscow, who seriously underestimated the military capabilities and diplomatic leverages of the US-led West. The origin of this adventurism, this paper argues, lays in the CCP's civil war experience with their Nationalist adversaries, which featured a preference of mobile warfare over positional warfare, and an opportunist attitude on cease-fire. This adventurism ended only when Communist front line came to the verge of collapse in June 1951.
Finding Terroir in Southwest Iowa
Terroir combines the physical landscape of the vineyard with the grapevines and the methods and techniques used to produce wine from the grapes. This study used a GIS to identify the characteristics of the physical landscape in Pottawattamie, Mills, Montgomery, Fremont, and Page counties in southwestern Iowa. The components were combined in the GIS using a weighted linear index to identify areas suitable for vineyard development and to identify the general characteristics of the area. Vineyard owners were interviewed to help determine the weighting system to use in the GIS and to determine their perceptions of how the physical landscape impacts their vineyards, as well as to determine what grape varieties they plant in their vineyards and their decisions on making wine from these grapes. This information was collected to identify whether the vineyard owners had developed a sense of place for their vineyards and how this sense might aid them in the development of a terroir for their wines. The resulting perceptions about the individual wineries were then considered in conjunction with the results from the GIS modeling to understand how the physical landscape influences the concepts of sense of place and terroir in southwest Iowa. The physical landscape of southwest Iowa was fairly uniform, as were the grape varietals planted in the vineyards. This created a measure of similarity among the wineries, while individuality between wineries was then created by the wine-makers as they used different techniques to produce wine from the grapes. This allows each winery to develop a sense of place, yet be part of a larger sense of place that encompasses multiple wineries within the area.
Innovations in Musical Texture and Aural Perspective: Steven Mackey's See Ya Thursday for Solo Marimba
This dissertation and accompanying lecture recital explore the unique textural features in the works of Steven Mackey as exhibited in See Ya Thursday (1993).A rigorous formal, harmonic, and motivic analysis will highlight the compositional characteristics of textural structure and aural perspective that exist in the work. Illumination of these compositional elements can help to identify and minimize the technical complexities that exist within this piece for the performer. In addition, this document provides brief biographical information on Steven Mackey and his works, and on See Ya Thursday as it relates to other pieces in the advanced marimba literature. Finally, it is the aim of the author to add a resource to the relatively limited amount of research on Steven Mackey with this analysis of See Ya Thursday.
L'emploi variable des signes diacritiques dans le français tchaté : une étude variationniste en temps apparent .
After providing an historical overview of the French spelling system and orthographic variation, this study analyzes selected internal (i.e., linguistic) factors and one external (i.e., social) factor that can influence the use of diacritics in online French-language chat sessions. From a corpus of synchronous computer-mediated communication, 3,855 tokens of graphemes capable of bearing diacritics were coded with the following scheme: Letter, Diacritic, Grapheme (i.e., Letter and Diacritic combined), Date of Participation, and Age Group of Participant. A multivariate (VARBRUL) analysis determined that Grapheme exerts the most influence on variation.
The Enemy of My Enemy Is What, Exactly? the British Flanders Expedition of 1793 and Coalition Diplomacy
The British entered the War of the First Coalition against Revolutionary France in 1793 diplomatically isolated and militarily unprepared for a major war. Nonetheless, a French attack on the Dutch Republic in February 1793 forced the British to dispatch a small expeditionary force to defend their ally. Throughout the Flanders campaign of 1793, the British expeditionary force served London as a tool to end British isolation and enlist Austrian commitment to securing British war objectives. The 1793 Flanders campaign and the Allied war effort in general have received little attention from historians, and they generally receive dismissive condemnation in general histories of the French Revolutionary Wars. This thesis examines the British participation in the 1793 Flanders campaign a broader diplomatic context through the published correspondence of relevant Allied military and political leaders. Traditional accounts of this campaign present a narrative of defeat and condemn the Allies for their failure to achieve in 1793 the accomplishments of the sixth coalition twenty years later. Such a perspective obscures a clear understanding of the reasons for Allied actions. This thesis seeks to correct this distortion by critically analyzing the relationship between British diplomacy within the Coalition and operations in Flanders. Unable to achieve victory on their own strength, the British used their expeditionary force in Flanders as diplomatic leverage to impose their objectives on the other powers at war with France.
Examining the Role of Latitude and Differential Insolation in Asymmetrical Valley Development
Valley development through erosional processes typically tends to create symmetrical valleys. Over time, water cuts through the substrate to create valleys, gorges, and canyons for which the sides are the valley are evenly sloped. However, there are anomalies to this process. Asymmetrical valleys have been well-documented even in areas of uniform substrate or little tectonic uplift. One proposed explanation for the asymmetry of these valleys is differential insolation. This may lead to different microclimates from one slope to another which alter the rate and extent of erosion. Since the differences in received insolation vary with latitude (especially in streams that flow along an east/west axis), it follows that the degree of asymmetry should also vary with latitude if differential insolation is a primary driving factor in the development of these valleys. To evaluate if insolation plays a role in the development of asymmetrical valleys, this study examines variability in asymmetry across 447 valleys in nine study areas located at different latitudes. The degree of asymmetry for each valley was measured by using 30 meter resolution digital elevation models (DEMs) to determine the slope angle of each side of the valley. Asymmetry was measured by computing a ratio of the average slope angle for each side of the valley (larger value divided by smaller). If the resulting value is one, the valley is deemed symmetrical. As the value increases, the degree of asymmetry increases. This investigation found that contrary to expectations, valleys at lower latitudes tend to have a higher degree of asymmetry than those at higher latitudes, which suggests that differential insolation does not play a major role in the development of these valleys. Instead, this study found that high altitudes and low latitudes are more frequently associated with a higher degree of asymmetry. These unexpected findings open the door …
The Role of Attachment in Perceptions of Interparental Conflict and Behavior Problems in Middle Childhood
The current study investigated the association of interparental conflict, parent-child attachment, and children's behavior problems in middle childhood. Although the effects of interparental conflict have been studied extensively, there has been little research done in the developmental period of middle childhood. This study examined the potential mediating role of the attachment relationship between parents and children in a community sample consisting of 86 two-parent families with at least one child between the ages of 8-11. Path modeling procedures indicated that attachment security serves as a mediator between interparental conflict and child behavior problems based on child reports. In particular, child-reported attachment security to the mother significantly mediated the association between children's perceptions of threat from interparental conflict and child-reported internalizing and inattentive/hyperactive symptoms. Child-reported attachment security to the father was not a significant mediator and mediation was not supported in parent-report models. The current findings have implications for families experiencing conflict and speak to the importance of attachment in the parent-child relationship when explaining the association between instances of interparental conflict and child behavioral outcomes. In particular, parents who engage in conflict can prevent the damaging effects of that conflict by making the conflict less overt, explaining to children the reasons for the conflict, and providing children with some assurance that a secure parent-child and interparental relationship is still present, despite the conflict.
Correlates Between Adult Romantic Attachment Patterns and Dimensional Personality Pathology
Previous research has suggested that adult attachment disturbance is related to maladaptic interaction patterns and personality disorder constructs. Specifically, research indicates that those with attachment disturbance are significantly more likely to meet criteria for a number of personality disorders, including borderline personality disorder, narcissistic personality disorder, and antisocial personality disorder. The purpose of this study was to investigate the associations between adult attachment and the new dimensional model of personality disorders scheduled to be released in the Diagnostic and Statistical Manual for Mental Health Diosrders (5th ed.) in spring 2013. Participants completed the Schedule for Adaptive and Nonadaptive Personality (SNAP) to measure dimensional personality functioning and the Experiences in Close Relationships (ECR-R) and the Attachment Prototypes to measure adult attachment patterns. Additionally, select scales from the Personality Assessment Inventory (PAI) and the Five Factor Model (FFM) will be utilized as secondary measures of personality patterns. The results suggest strong associations between adult attachment orientations and specific maladaptive personality characteristics.
Programming for the Latino Youth: a Content Analysis of Prime Time Television Programs By Three Spanish-language Broadcast Networks
This study reviews U.S. Spanish-language broadcast networks' prime time programming content targeted to the Latino youth audience. It explores the relationship between the Latino youth and prime time programming by Spanish-language broadcast networks and how they seek to attract this market as is reflected in the characteristics and quantity of their content and preferred formats by using the strategic management theory. This study identifies the amount and type of prime time programming that was catered to the Latino youth audience between 2003 and 2012 by the three major Spanish-language networks: Univision, Telemundo, and Telefutura. An observed pattern reveals that prime time programming targeting Latino teenagers is relatively smaller and older in comparison to programming delivered through the general programming.
An Examination of Resnick's Model of Malingering: a Pai Study of Feigned Ptsd
Malingered posttraumatic stress disorder (PTSD) poses a formidable clinical challenge in personal injury and disability cases because of the apparent ease in feigning PTSD and the supposed link (proximate cause) to the claimed damages. The effective assessment of feigned PTSD is particularly challenging because this diagnosis is both easier to fake than other Axis I disorders and more difficult to detect. As an additional confound, some patients with genuine PTSD produce highly variable, elevated profiles on multiscale inventories that are difficult to distinguish from feigned PTSD. The current study examined whether the Personality Assessment Inventory (PAI) can effectively differentiate between genuine and feigned PTSD in 109 inpatients from a trauma unit. The two most effective scales were the MAL and the NDS scales. As a primary focus, the current study was the first empirical investigation of Resnick's model of malingered PTSD that is comprised of three subtypes: pure malingering (pure-M), partial malingering (partial-M), and false imputation (false-I). The primary goal was to evaluate whether each feigning group was able to (a) effectively simulate PTSD symptoms and diagnoses and (b) avoid being classified as feigning. The partial-M group proved to be the best feigning group in achieving these two goals. Furthermore, the use of well-defined groups, including an indeterminate band (i.e., unclassified) around each cut score, was explored. Overall, the use of well-defined groups improved accuracy in classification and reduced the number of false-positives.
Comparative Phyto-uptake Across Distribution Coefficients of Pharmaceutical Compounds and Aquatic Macrophytes: Carbamazepine and Amiodarone Uptake in Lemna Spp
Few studies have been conducted on the effectiveness of phytoremediation of pharmaceutical compounds, although the persistent and non-acutely toxic nature of many of these compounds in today's water bodies may yield an ideal application for this practice. To quantify the potential effectiveness of plant uptake, kinetic and proportional bioconcentration factors (BCFk, and BCFp, respectively) in nanograms (ng) carbamazepine and amiodarone per gram (g) wet weight plant tissue for Lemna spp. were determined utilizing a 14-day continuous flow-through study. Samples were analyzed using isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) running in positive ion mode. Kinetic BCF was estimated at 0.538, while proportional BCF was estimated at 0.485. Kinetic BCF for the amiodarone study was estimated at 23.033, whereas proportional BCF was estimated at 41.340. Possible contamination of the C18 column and peristaltic pump failure may have impacted uptake results. In light of variability and current lack of research in the field, this work should be considered exploratory rather than conclusive.
Determination of the Optimal Number of Strata for Bias Reduction in Propensity Score Matching.
Previous research implementing stratification on the propensity score has generally relied on using five strata, based on prior theoretical groundwork and minimal empirical evidence as to the suitability of quintiles to adequately reduce bias in all cases and across all sample sizes. This study investigates bias reduction across varying number of strata and sample sizes via a large-scale simulation to determine the adequacy of quintiles for bias reduction under all conditions. Sample sizes ranged from 100 to 50,000 and strata from 3 to 20. Both the percentage of bias reduction and the standardized selection bias were examined. The results show that while the particular covariates in the simulation met certain criteria with five strata that greater bias reduction could be achieved by increasing the number of strata, especially with larger sample sizes. Simulation code written in R is included.
Student Experiences and Expectations Related to the Vertical Transfer Process From Two Feeder Community Colleges of a Senior Institution
The purpose of this study was to understand the experiences and expectations of community college students attending Temple College and Central Texas College regarding what they may expect as part of the vertical transfer process in order to improve the likelihood of their persistence to graduation at Texas A&M University-Central Texas (TAMUCT). The target population was approximately 700 students enrolled in two feeder Texas community colleges who had expressed intent to transfer to TAMUCT. The response rate was 19%, and 136 useable surveys were used for analysis. The sample was 74% female, 45% White with the majority minority. To assess the relationships between community college experiences and transfer expectation variables, correlations and logistic regression were used. No linear relationships were found regarding gender, age, ethnicity, highest level of parents' education, the aspirational variables of highest academic degree intend to obtain at any college or university and at TAMUCT, and the feeder community college attended and the two scales. A statistically significant relationship was found between parental income level and reported community college experiences (F(4, 79) = 2.612, p = .042) and vertical transfer expectations (F(4, 52) = 3.318, p = .017). Community college students from lower socioeconomic backgrounds may utilize the community college to upper-level institution vertical transfer pathway as a way to obtain an affordable baccalaureate degree. Community colleges and university administrators need to continue working together to establish unique and creative ways to create seamless transitions for vertical transfer students utilizing the community college to upper-level institution pathway to degree completion.
Repetition and Difference: Parodic Narration in Kander and Ebb's "The Scottsboro Boys"
The American musical team John Kander and Fred Ebb created many celebrated works, yet musicologists have carried out little research on those works. This study examines the role of music in the parodic narration of Kander and Ebb's final collaboration, The Scottsboro Boys. Kander and Ebb use minstrelsy to tell the story of the historic Scottsboro Boys trials with actors portraying the Scottsboro Boys as minstrels; at the same time, they employ a number of devices to subvert minstrelsy stereotypes and thereby comment on racism. Drawing on African American literary theory, sociolinguistics, and Bakhtin's dialogism, this study illuminates how Signifyin(g), a rhetorical tradition used to encode messages in some African American communities, is the primary way the actors playing the Scottsboro Boys subvert through minstrelsy. This study not only contributes to the discussion of Signifyin(g) in African American musicals and theatre as a tool of subversion, but also provides an example of non-African American creators—Kander and Ebb—using Signifyin(g) devices. They use these in the music and the book; in particular, Kander and Ebb do some Signifyin(g) on Stephen Foster's plantation melodies.
Tax Compliance in a Social Setting: the Influence of Norms, Perceptions of Fairness, and Trust in Government on Taxpayer Compliance
Many taxing authorities, including those in the United States (U.S.), rely on voluntary tax compliance and continually search for ways to increase tax revenues. Most of these methods are costly and labor intensive, such as audits and penalties for noncompliance. Prior tax compliance research has heavily investigated the influence that economic factors, such as tax rates and penalties, have on individual compliance intentions. However, economic models fail to fully predict individual tax compliance. Psychology literature suggests that social factors may also play an important role in individual tax compliance decisions. The purpose of this study is to examine the influence that social and psychological factors have on individuals' tax compliance intentions. Specifically, a model of taxpayer compliance is hypothesized that suggests that norms, perceived fairness of the tax system, and trust in government have a significant influence on compliance intentions. Results of a survey of 217 U.S. taxpayers found support for the influence of social factors on tax compliance. This research concludes that social norms have an indirect influence on compliance intentions through internalization as personal norms. Specifically, as the strength of social norms in favor of tax compliance increase, personal norms of tax compliance also increase, and this leads to a subsequent increase in compliance intentions. This dissertation also finds that trust in government and the perceived fairness of the tax system have a significant influence on compliance intentions. Supplemental analyses indicate that trust in government fully mediates the relationship between perceived fairness of the tax system and compliance intentions. This research offers several contributions to accounting literature and provides valuable insight for taxing authorities. First, this study examines taxpayer compliance from a psychological, rather than an economics driven, perspective. The suggested model of taxpayer compliance posits that social norms have a significant influence on compliance intentions. This information …
A Vehicle-collision Learning System Using Driving Patterns on the Road
Demand of automobiles are significantly growing despite various factors, steadily increasing the average number of vehicles on the road. Increase in the number of vehicles, subsequently increases the risk of collisions, characterized by the driving behavior. Driving behavior is influenced by factors like class of vehicle, road condition and vehicle maneuvering by the driver. Rapidly growing mobile technology and use of smartphones embedded with in-built sensors, provides scope of constant development of assistance systems considering the safety of the driver by integrating with the information obtained from the vehicle on-board sensors. Our research aims at learning a vehicle system comprising of vehicle, human and road by employing driving patterns obtained from the sensor data to develop better systems of safety and alerts altogether. The thesis focusses on utilizing together various data recorded by the in-built embedded sensors in a smartphone to understand the vehicle motion and dynamics, followed by studying various impacts of collision events, types and signatures which can potentially be integrated in a prototype framework to detect variations, alert drivers and emergency responders in an event of collision.
Values and Valuing in a College Population
Values and valuing behavior have many conceptualizations. Despite how they are defined, values have a significant impact on behavior and are idiosyncratic in nature. The present study reviewed values research and sought to explore values identification and successful valued living among an archived sample of university students. Specifically, in a convenience sample of 282 undergraduate students, variables that affect values identification and behavior such as ethnicity, gender, psychological distress, and psychological flexibility were identified. Results indicated that university students identified with more than one valued living domain (as measured by the PVQ) and that contextual factors such as ethnicity, gender, age, and religiosity/spirituality were associated with specific values endorsed. Furthermore, psychological distress, including depression and anxiety (as measured by the DASS) was negatively correlated with values purity – the extent to which values are freely chosen. Finally, psychological flexibility (low experiential avoidance as measured by the AAQ-2), predicted values purity and successful living in accordance with identified values, and the relationship between these two variables was mediated by psychological flexibility.
Exploring Aspects of Korean Traditional Music in Young Jo Lee's Piano Honza Nori
Since the 1960s, several gifted Korean composers, including perhaps most notably Young Jo Lee (b. 1943), have been internationally acclaimed for their work. In Western countries, however, there has been a scarcity of academic studies examining the artistry of the music of these Korean composers. Nonetheless, as one of today's most recognized composers in Korea, Young Jo Lee has been invited to numerous international concerts, conferences, and festivals where his works have been played and discussed. A salient feature of his compositions is the fusion of Korean traditional music and the elements of Western compositions, such as in, for one distinctive example, his piano composition, Piano Honza Nori. This musical study describes and analyzes how Lee integrates Korean traditional elements with Western musical ideas in Piano Honza Nori. Results of this study will contribute to the limited literature on the analysis of contemporary piano composition that integrates Korean traditional elements.
An Examination of the Similarities and Differences Between Transformational and Authentic Leadership and Their Relationship to Followers' Outcomes
To date there is no comprehensive understanding of what leadership is, nor is there an agreement among different theorists on what a good or effective leader should be. The purpose of this dissertation is to examine the theoretical and empirical similarities and differences of two styles of leadership – transformational and authentic leadership. Follower outcomes, as well as, the effects of trust and psychological capital within these paradigms are of particular interest. Although theoretical differences are proposed for the leadership style, the extent of overlap suggests the need to more closely examine each theory. Pilot studies were created to validate original scenarios created for the study as well as to examine the validity and reliability of new measurement instruments. The dissertation is designed to determine whether the relationships between authentic leadership and a variety of follower outcomes including performance, affective commitment, satisfaction, trust, and organizational citizenship behavior are similar to those between transformational leadership and these outcomes. In addition, variables more unique to authentic leadership research including psychological capital and follower well-being were examined within both paradigms to determine whether their relationships are similar to each type of leadership style. An experimental study using Qualtrics was used to collect the data with the expectation that there would be significant differences in the two styles of leadership such that each explains unique variance in follower behavior. The results of this dissertation support the lack of perceptual difference between the two theories of leadership. The results of this experiment do not come completely unexpected because of the ethical overlap between the two styles of leadership. Although subjects in the experiment could differentiate authentic leadership from transformational leadership based on the manipulations, authentic leadership effects were not significantly different when compared to transformational leadership effects. As a result, analyses in my research do …
Development of Novel Semi-conducting Ortho-carborane Based Polymer Films: Enhanced Electronic and Chemical Properties
A novel class of semi-conducting ortho-carborane (B10C2H12) based polymer films with enhanced electronic and chemical properties has been developed. The novel films are formed from electron-beam cross-linking of condensed B10C2H12 and B10C2H12 co-condensed with aromatic linking units (Y) (Y=1,4-diaminobenzene (DAB), benzene (BNZ) and pyridine (PY)) at 110 K. The bonding and electronic properties of the novel films were investigated using X-ray photoelectron spectroscopy (XPS), UV photoelectron spectroscopy (UPS) and Mulliken charge analysis using density functional theory (DFT). These films exhibit site-specific cross-linking with bonding, in the pure B10C2HX films, occurring at B sites non-adjacent to C in the B10C2H12 icosahedra. The B10C2H12:Y films exhibit the same phenomena, with cross-linking that creates bonds primarily between B sites non-adjacent to C in the B10C2H12 icosahedra to C sites in the Y linking units. These novel B10C2HX: Y linked films exhibit significantly different electron structure when compared to pure B10C2HX films as seen in the UPS spectra. The valence band maxima (VBM) shift from - 4.3 eV below the Fermi level for pure B10C2HX to -2.6, -2.2, and -1.7 for B10C2HX:BNZ, B10C2HX:PY, and B10C2HX:DAB, respectively. The top of the valence band is composed of states derived primarily from the Y linking units, suggesting that the bottom of the conduction band is composed of states primarily from B10C2H12. Consequently these B10C2HX:Y films may exhibit longer electron-hole separation lifetimes as compared to pure B10C2HX films. This research should lead to an enhancement of boron carbide based neutron detectors, and is of potential significance for microelectronics, spintronics and photo-catalysis.

A Performer's Guide to Béla Bartók's Violin Concerto No 1, Opus Posthumous, 1907–1908
Despite Bartók's lasting international fame, some of his works remain unjustly lesser-known. One of the pieces that still resides in relative obscurity is his Violin Concerto No.1—a gem of the violin repertoire that must be brought to the broader public's attention. The fact that the concerto was hidden definitely contributed to its little–known status at first. However, the most important cause for the lack of enthusiasm to tackle this terrific work lies in the unorthodox demands it puts on the violinist. The purpose of this paper is to provide musical and technical suggestions based on Bartók's performing style and on his requirements for performer, which will help to create a more persuasive interpretation of the piece. The guide covers the questions of character, articulation, dynamics, and other performance aspects, and also provides practical suggestions, such as fingerings and bowings. It is hoped that this study will help violin performers to gain additional knowledge and insight into this composition and encourage more frequent performances of it.
The Integration of Western Techniques with East Asian Philosophies in Isang Yun's Quartett Für Horn, Trompete, Posaune Und Klavier
Korean composer Isang Yun (1917-1995) was one of the few successful Asian avant-garde composers to blend philosophical elements from East Asia with Western techniques such as the twelve-tone method, Hauptton, Hauptklang, and Umspielung. In addition to the integration of Western and Eastern influences, a significant feature of Yun´s compositional language, found throughout his oeuvre, is the application of East Asian philosophical tenets into his works. The purpose of this dissertation is to develop a greater understanding of Isang Yun's life and music, more specifically the Quartett für Horn, Trompete, Posaune und Klavier. The dissertation is divided into five chapters. The first chapter of the dissertation presents introductory data, including the purpose and significance of the study. The second chapter provides pertinent biographical facts about Isang Yun and his works, obtained through research of authoritative books, journal articles, and interviews. The third chapter offers references to traditional Korean brass instruments in terms of their historical background, structure, and timbre. In addition, it also focuses on the processes by which Yun incorporated the compositional techniques of Hauptton, Hauptklang, and Umspielung to the work and their relation to Tao philosophy. The fourth chapter consists of an analytical and stylistic study of the Quartett; Yun's compositional language and formal structure are examined based on a stylistic assessment of selected examples from the work. The fifth and last chapter is a conclusion.
Effects of Suspended Multi-Walled Carbon Nanotubes on Daphnid Growth and Reproduction
Multi-walled carbon nanotube aggregates can be suspended in the aqueous phase by natural organic matter. These aggregates are ingested by filter feeding zooplankton. Ingested aggregates result in decreased growth and decreased reproduction. These effects may be caused by reduction in energy input from normal feeding behavior. pH alters natural organic matter structure through changes in electrostatic repulsion. Altered natural organic matter structure changes multi-walled carbon nanotube aggregate size. This size variation with variation in pH is significant, but not large enough a change in size to alter toxicity, as the aggregate size range remains well within the particle size selection of the organisms.
Design and Application of Phased Array System
Since its invention, phased array has been extensively applied in both military and civil areas. The applications include target detecting and tracking, space probe communication, broadcasting, human-machine interfaces, and remote sensing. Although the phased array applications show a broad range of potential market, there are some limitations of phased array's development: high cost, complex structure, narrow bandwidth, and high power consumption. Therefore, novel ideas are needed to reduce these constraints. In this thesis, several new approaches about the design and application of phased array are presents. First, the principle of phased array and fundamental design equations are introduced. Second, a new application of phased array antenna for radar respiration measurement is presented. By integrating a 4×4 Butler matrix with four-element antenna array, there will be four distinct main beams in radiation pattern. This new approach can improve the measurement accuracy and realize a high detecting rate. Third, a compact phased array antenna system based on dual-band operations is introduced. Dual-band function can make N-antenna system obtain 2N unique radiation beams (N is an integer) and achieve a significant size reduction compared to the conventional single-band system. To verify the design concept, a four-element phased array antenna working at 5GHz and 8GHz is designed and fabricated. The measurement results make a good agreement with the simulations. Finally, a novel architecture of steering phase feeding network by using bi-directional series-fed topology is presented. This bi-directional series-fed network needs less phase shifters and realizes steering phase function by applying control voltage.
The Ideological Appropriation of La Malinche in Mexican and Chicano Literature
La Malinche is one of the most controversial figures in Mexican and Chicano literature. The historical facts about her life before and after the Spanish Conquest are largely speculative. What is reliably known is that she had a significant role as translator, which developed into something of mythic proportions. The ideological appropriation of her image by three authors, Octavio Paz, Laura Esquivel and Cherríe Moraga, are explored in this thesis. The full extent of the proposed rendition of La Malinche by Octavio Paz is the basis of the second chapter. The conclusion drawn by Paz, in The Labyrinth of Solitude (1950) is that La Malinche is what he calls la chingada [the raped/violated one] and proposes that all women are always open to conquest, sexually and otherwise. Laura Esquivel's novel Malinche (2006) is a re-interpretation that focuses on the tongue as the source of power and language as the ultimate source of autonomy for La Malinche. This aspect of La Malinche and the contrast of Paz's understanding are the basis of the third chapter of this thesis. Cherríe Moraga, in Loving in the War Years (1983), proposes that if women are to be traitors, it is not each other that they should betray but their cultural roles as mothers and wives. She writes that in order to avoid being the one who is passively colonized, women often times become el chingón. However, ultimately women are free of these limiting dichotomous roles are able to autonomously define themselves in a way that goes beyond these labels. This is only possible when La Malinche is re-interpreted by these by different authors.
Centers of Invariant Differential Operator Algebras for Jacobi Groups of Higher Rank
Let G be a Lie group acting on a homogeneous space G/K. The center of the universal enveloping algebra of the Lie algebra of G maps homomorphically into the center of the algebra of differential operators on G/K invariant under the action of G. In the case that G is a Jacobi Lie group of rank 2, we prove that this homomorphism is surjective and hence that the center of the invariant differential operator algebra is the image of the center of the universal enveloping algebra. This is an extension of work of Bringmann, Conley, and Richter in the rank 1case.
A Relationship-based Cross National Customer Decision-making Model in the Service Industry
In 2012, the CIA World Fact Book showed that the service sector contributed about 76.6% and 51.4% of the 2010 gross national product of both the United States and Ghana, respectively. Research in the services area shows that a firm's success in today's competitive business environment is dependent upon its ability to deliver superior service quality. However, these studies have yet to address factors that influence customers to remain committed to a mass service in economically diverse countries. In addition, there is little research on established service quality measures pertaining to the mass service domain. This dissertation applies Rusbult's investment model of relationship commitment and examines its psychological impact on the commitment level of a customer towards a service in two economically diverse countries. In addition, service quality is conceptualized as a hierarchical construct in the mass service (banking) and specific dimensions are developed on which customers assess their quality evaluations. Using, PLS path modeling, a structural equation modeling approach to data analysis, service quality as a hierarchical third-order construct was found to have three primary dimensions and six sub-dimensions. The results also established that a country's national economy has a moderating effect on the relationship between service quality and investment size, and service satisfaction on investment size. This study is the first to conceptualize and use the hierarchical approach to service quality in mass services. Not only does this study build upon the investment model to provide a comprehensive decision model for service organizations to increase their return on investment but also, provides a congruence of work between service quality and the investment model in the management and decision sciences discipline.
Metabolic Engineering in Plants to Control Source/sink Relationship and Biomass Distribution
Traditional methods like pruning and breeding have historically been used in crop production to divert photoassimilates to harvested organs, but molecular biotechnology is now poised to significantly increase yield by manipulating resource partitioning. It was hypothesized that metabolic engineering in targeted sink tissues can favor resource partitioning to increase harvest. Raffinose Family Oligosaccharides (RFOs) are naturally occurring oligosaccharides that are widespread in plants and are responsible for carbon transport, storage and protection against cold and drought stress. Transgenic plants (GRS47, GRS63) were engineered to generate and transport more RFOs through the phloem than the wild type plants. The transgenic lines produced more RFOs and the RFOs were also detected in their phloem exudates. But the 14CO2 labeling and subsequent thin layer chromatography analysis showed that the RFOs were most likely sequestered in an inactive pool and accumulate over time. Crossing GRS47 and GRS63 lines with MIPS1 plants (that produces more myo-inositol, a substrate in the RFO biosynthetic pathway) did not significantly increase the RFOs in the crossed lines. For future manipulation of RFO degradation in sink organs, the roles of the endogenous α-galactosidases were analyzed. The alkaline α-galactosidases (AtSIP1 and AtSIP2 in Arabidopsis) are most likely responsible for digesting RFOs in the cytoplasm and may influence the ability to manipulate RFO levels in engineered plants. Atsip1/2 (AtSIP1/AtSIP2 double-knockout plants) were generated and phenotypically characterized based on seed germination patterns, flowering time, and sugar content to observe the impact on RFO sugar levels. The observations and analysis from these lines provide a basis for further insight in the manipulation of resource allocation between source and sink tissues in plants for future research.
José Antonio Gómez´s Versos Para Órgano (Section I): a Practical Guide for Performance
José Antonio Gómez is an important figure in Mexican music history and his works are considered representative of the beginning of Mexico´s Independent era. Some musicians are familiar with Gómez´s choral output but his organ music is rarely considered. Due to the lack of an edition of Gómez´s Versets for Organ, a practical guide was found needed to aid its performance. This study is based on performance, analysis, and direct work on the only known source for it. The first chapter, Introduction, presents the argument for an edited version of the first part of the manuscript as a performance guide. The second provides biographical information on the composer. The third chapter discusses the background for the original performance of the Versets for Organ. Chapter 4 provides performance considerations for the works. The edition of the manuscript is included in chapter 5.
A Study of Mechanisms to Engineer Fine Scale Alpha Phase Precipitation in Beta Titanium Alloy, Beta 21S
Metastable b-Ti alloys are titanium alloys with sufficient b stabilizer alloying additions such that it's possible to retain single b phase at room temperature. These alloys are of great advantage compared to a/b alloys since they are easily cold rolled, strip produced and can attain excellent mechanical properties upon age hardening. Beta 21S, a relatively new b titanium alloy in addition to these general advantages is known to possess excellent oxidation and corrosion resistance at elevated temperatures. A homogeneous distribution of fine sized a precipitates in the parent b matrix is known to provide good combination of strength, ductility and fracture toughness. The current work focuses on a study of different mechanisms to engineer homogeneously distributed fine sized a precipitates in the b matrix. The precipitation of metastable phases upon low temperature aging and their influence on a precipitation is studied in detail. The precipitation sequence on direct aging above the w solvus temperature is also assessed. The structural and compositional evolution of precipitate phase is determined using multiple characterization tools. The possibility of occurrence of other non-classical precipitation mechanisms that do not require heterogeneous nucleation sites are also analyzed. Lastly, the influence of interstitial element, oxygen on a precipitation during the oxidation of Beta 21S has been determined. The ingress of oxygen and its influence on microstructure have also been correlated to measured mechanical properties.
The Enameling Arts in Kuwaiti Pre-service Art Teacher Education
The purpose of this study was twofold: (1) to examine the knowledge, skills, and experiences in the enameling arts and the attitudes and perceptions of in-service (n = 12) and pre-service Kuwaiti art teachers (n = 170), art supervisors at the Ministry of Education (MOE) (n = 3) and art education faculty members at the College of Basic Education (CBE) and Kuwait University (KU) (n = 8) about what they believed pre-service art teachers should know and be able to do in order to teach the enameling arts, and (2) to use this information to inform and guide the development of a content outline for an enameling course for pre-service Kuwaiti art teachers that is educationally (how to perform enameling arts skills and how to teach what they know), practically (safety issues, workshop management, etc), and culturally (its relation to Islamic culture) suitable. Both quantitative and qualitative approaches were used. Most of the respondents revealed limited knowledge and skills and modest experiences in the enameling arts. All interviewees in the study expressed positive perceptions and attitudes about the enameling arts. Most agreed that a revision to the current art education curriculum at the CBE was needed and made suggestions about how the curriculum should be revised. It was clear that there is a disconnection and miscommunication between the MOE and the CBE with regards to the information about enameling that should be covered and taught in the art education classes. All respondents expressed support for the inclusion of a course in enameling in the art education curriculum at the CBE. Because of the limited knowledge of the participants in the study, they were not able to provide guidance in shaping the content for a course in the enameling arts. The researcher had to rely on the literature review and his …
Information Seeking Behavior of Crime Scene Investigators in the Turkish National Police
This exploratory research is the first one among occupational information seeking behavior studies that focuses on information seeking behaviors of the crime scene investigators. The data used in this dissertation were gathered via a self-administrated survey instrument from 29 cities in Turkey. Findings obtained from the data analyses show that there is a strongly positive relationship between the experience of the crime scene investigators and the use of personal knowledge and experience as a primary information source (experience is operationalized with age, service years in policing, and service years in crime scene investigation units). The findings also suggest that increasing of the level of education is negatively related to relying on immediate colleagues as an information source among the crime scene investigators. These findings are consistent with related literature and theory. The data analysis shows that crime scene investigators work in cities with higher population rates have more complaint scores than those who work in cities with lower population rates across Turkey. The findings from the data analysis may suggest valuable implications to defeat the barriers between crime scene investigators and information sources. The researcher drew a proposed theoretical framework of an information behavior concept in the context of crime scene investigation that may help those who are interested in the phenomenon and its applications to other contexts.
Geographic Distance, Contact, and Family Perceptions of Quality Nursing Home Care
The effect of frequency of nursing home contact on family perceptions of quality care is the focus of this research. A family member characteristic, such as geographic distance from the nursing home, affects his or her frequency of contact with the nursing home. Frequency of contact, in turn, affects family perceptions of the care his or her loved one receives in the nursing home. The theoretical framework for this study is based on Allport's intergroup contact theory, which posits that when four contact conditions - institutional support, equal status, common goals, and intergroup cooperation - are present in an intergroup situation, a reduction in anxiety between groups is likely to occur. Regression analysis tested the stated hypotheses using survey data collected from 275 family members of residents in 10 Dallas-Ft. Worth area nursing homes. This study is among the first to quantify family geographic distance, finding that family geographic distance is a significant negative predictor of nursing home contact. Additionally, results build on Allport's theory by extending its' usefulness to nursing home organizations in two distinct ways. First, findings support Allport's premise that contact alone between groups - i.e., family members and nursing home staff - is insufficient for increasing or decreasing family perceptions of nursing home care. Second, three of the four contact conditions included in Allport's theory were statistically supported by the data. In sum, findings of this research provide nursing homes with an empirically tested model for improving family perceptions of quality nursing home care.
Tracing the Path of Sustainable Development through Major International Conferences: A Brief History and Overview of Sustainable Development 1964-2002
Starting with the idea that unsustainable practices contribute to issues of social justice and poverty as much as to ecological issues. Chapter 1 traces the origins of the terms sustainable and development individually to see how it is that they came together. Chapter 2 traces the major international conferences and documents and their use of the terms sustainable development. Chapter 3 takes a phenomenology approach to get a bit deeper into sustainable development. I examine the most commonly cited definition of sustainable development as well as a broader definition of sustainable development as a process of change. Chapter 4 examines the field of environmental ethics and argues that constant debates over value distract policy makers from the central question of what morally motivates people to support environmental ethics views. Chapter 5 examines the institution and regime building process, and the conclusion offers three questions to measure our progress.
Stretching the Flexible Myosin II Subfragment Using the Novel Gravitational Force Spectroscope, and the Uncoiling of S2
Familial Hypertrophic cardiomyopathy (HCM) causes ventricle walls to thicken and often leads to sudden death especially in adults. Mutations in the subfragment 2 (S2) of β-cardiac myosin are implicated in the genetic disorder. This S2 region is a coiled-coil rod region resulting from the dimeric form of myosin II. It has been proposed that an elastic quality allows normal S2 to absorb force during the powerstroke according to the sliding filament model. To test the flexibility of single molecules of S2 against levels of physiological force, the Gravitational Force Spectrometer (GFS) is being developed. This novel system employs a standard microscope on an equatorial mount that allows the spectrometer to be rotated freely in space. Stationary glass beads are attached to a microscope slide where the molecule is tethered between the stationary bead and a smaller mobile bead. The GFS is oriented so that the force of gravity can act on the mobile bead and so impart a small force to the tethered subfragment. Additionally, a video system in conjunction with ImageJ software makes a distance measurement of the molecule possible with a resolution of around 11 nm. The S2 can be stretched parallel or perpendicular to the coiled coil to elucidate different structural properties of the rod. This study is the first to show structural evidence that S2 in vertebrate skeletal myosin uncoils proportionally to physiological force loads. Because of this, the usefulness and promise of the novel GFS is highlighted, and the biological role of S2's flexibility can be directly commented on. If the dimer undergoes uncoiling at physiological force loads as shown, then it is reasonable to think that this might occur in nature in response to the stress of the powerstroke on a single molecule. This unwinding could be to absorb force as a mechanism to …
Self-Objectification and Sport Participation: Do the Gendered Makeup and Competitive Level of the Team Matter?
The purposes of this study were to (a) investigate differences in self-objectification, self-surveillance, body shame, and flow among female athletes on all-women's and coed ultimate frisbee teams at different competitive levels, and (b) examine the objectification theory model across groups. Participants (n = 112) completed online surveys including a demographic questionnaire, trait and state versions of the Self-Objectification Questionnaire, Body Surveillance and Body Shame subscales of the Objectified Body Consciousness Scale, and the Flow State Scale. No differences in self-objectification, self-surveillance, or body shame were found, although highly competitive athletes experienced more flow than lower competitive teams. Relationships were found between self-objectification, self-surveillance, and body shame, but not for flow, partially supporting the objectification theory model.
Using Geographic Information Systems for the Functional Assessment of Texas Coastal Prairie Freshwater Wetlands Around Galveston Bay
The objective of this study was to deploy a conceptual framework developed by M. Forbes using a geographic information system (GIS) approach to assess the functionality of wetlands in the Galveston Bay Area of Texas. This study utilized geospatial datasets which included National Wetland Inventory maps (NWI), LiDAR data, National Agriculture Imagery Program (NAIP) imagery and USGS National Land Cover data to assess the capacity of wetlands to store surface water and remove pollutants, including nitrogen, phosphorus, heavy metals, and organic compounds. The use of LiDAR to characterize the hydrogeomorphic characteristics of wetlands is a key contribution of this study to the science of wetland functional assessment. LiDAR data was used to estimate volumes for the 7,370 wetlands and delineate catchments for over 4,000 wetlands, located outside the 100-yr floodplain, within a 2,075 square mile area around Galveston Bay. Results from this study suggest that coastal prairie freshwater wetlands typically have a moderate capacity to store surface water from precipitation events, remove ammonium, and retain phosphorus and heavy metals and tend to have a high capacity for removing nitrate and retainremove organic compounds. The results serve as a valuable survey instrument for increasing the understanding of coastal prairie freshwater wetlands and support a cumulative estimate of the water quality and water storage functions on a regional scale.
An Assessment of Consumers' Willingness to Patronize Foreign-Based Business Format Franchises: An Investigation in the Fast-Food Sector
This study aimed to address consumers' stereotypical categorizations in the form of essentialist views about foreign cultures and their effect on individual consumers, including their negative or aroused emotions and subsequent retail patronage behaviors. The research mission was to empirically assess the salient dimensions of consumers' states of mind (positive and negative affect, psychological essentialism, epistemic curiosity), states of being (store atmospherics), and states of action (retail patronage behaviors) in a cultural context based on Mehrabian-Russell theory of environmental psychology. Specifically, the retail patronage setting was selected as foreign-based fast-food franchises because it represents both a relevant and timely situational context for consumer behavior. This dissertation makes several contributions to international retail patronage literature. First, it frames curiosity as an aroused emotional state and finds support for the relationship between consumer epistemic curiosity and retail patronage. Second, it provides support for the linkage between consumer affect and retail patronage in an international retail setting. Third, it reveals that affect has a greater impact on retail patronage than epistemic curiosity. The overarching finding of this study is an inability to tie the cultural elements in retail atmospherics, including signs, symbols, and artifacts, to consumer emotions. In addition, we were unable to frame psychological essentialism as a personality trait that would reduce the levels of affect and curiosity in retail store environments characterized by foreign-cultural elements.
Fractus I for Trumpet in C and Electronic Sound: A Critical Examination of the Compositional Process
Fractus I is a composition for trumpet in C and live electronic sound. The electronics were primarily created using SuperCollider, an environment and programming language for real time audio synthesis. This project investigates SuperCollider's pattern and task functionality as a means of supporting and enriching the compositional process. Fractus I develops several different code architectures in order to randomize as well as synchronize various musical elements. The piece exploits SuperCollider as both an audio synthesis tool and a performance conduit. Additionally, the nature of SuperCollider's patterns and tasks influences the form and content of the composition. The project underscores SuperCollider as a powerful, versatile and open-ended tool for musical composition and examines future directions and improvements.
Cracking the Closed Society: James W. Silver and the Civil Rights Movement in Mississippi
This thesis examines the life of James Wesley Silver, a professor of history at the University of Mississippi for twenty-six years and author of Mississippi: The Closed Society, a scathing attack on the Magnolia State's history of racial oppression. In 1962, Silver witnessed the campus riot resulting from James Meredith's enrollment as the first black student at the state's hallowed public university and claims this was the catalyst for writing his book. However, by examining James Silver's personal and professional activities and comparing them with the political, cultural, and social events taking place concurrently, this paper demonstrates that his entire life, the gamut of his experiences, culminated in the creation of his own rebel yell, Mississippi: The Closed Society. Chapter 1 establishes Silver's environment by exploring the history and sociology of the South during the years of his residency. Chapter 2 discusses Silver's background and early years, culminating with his appointment as a faculty member of the University of Mississippi in 1936. Chapter 3 reveals Silver's personal and professional life during the 1940s, as well as the era's notable historical events. The decade of the 1950s is discussed in chapter 4, particularly the civil rights movement, Silver's response to these changes, and those in his own life. Chapter 5 follows the path of James Meredith's integration of Ole Miss, the publication of Silver's book, and its aftermath. The conclusion is a brief epilogue of Silver's post-Mississippi life.
Analysis of Graduation Rates for Four-year Colleges: A Model of Institutional Performance Using IPEDS
Under the George W. Bush U.S. presidential administration, the federal government pushed for greater accountability among institutions of higher education for educational outcomes. Graduation rate is a key performance indicator of institutional accountability. Previous researchers of student attrition focused primarily on the effects of student level factors on student persistence/withdrawal behavior. Recently, researchers put more focus on the effects of institutional characteristics on graduation rates, but most of these studies were exploratory and based on multiple regression models. No institutional model has existed to synthesize their results within a theoretical framework. Such an institutional model is needed to explain the process of student persistence at the institutional level. The purpose of this study was to develop a model of institutional performance in graduation rate for four-year, public and private not-for-profit, Title IV institutions in the United States. This study validated the institutional model based on the IPEDS dataset using the structural equation modeling (SEM) technique. Further group comparison analyses are conducted by fitting the same SEM model to several subgroup datasets based on grouping variables such as control, geographical region and state. Benchmarking analyses were conducted to demonstrate how administrators and policy-makers can use the institutional model to compare the performance of an institution with its peers and what policy changes can they pursue to improve graduation rates.
Effect of Fluorine and Hydrogen Radical Species on Modified Oxidized Ni(pt)si
NiSi is an attractive material in the production of CMOS devices. The problem with the utilization of NiSi, is that there is no proper method of cleaning the oxide on the surface. Sputtering is the most common method used for the cleaning, but it has its own complications. Dry cleaning methods include the reactions with radicals and these processes are not well understood and are the focus of the project. Dissociated NF3 and NH3 were used as an alternative and XPS is the technique to analyze the reactions of atomic fluorine and nitrogen with the oxide on the surface. A thermal cracker was used to dissociate the NF3 and NH3 into NFx+F and NHx+H. There was a formation of a NiF2 layer on top of the oxide and there was no evidence of nitrogen on the surface indicating that the fluorine and hydrogen are the reacting species. XPS spectra, however, indicate that the substrate SiO2 layer is not removed by the dissociated NF3 and NiF2 growth process. The NiF2 over layer can be reduced to metallic Ni by reacting with dissociated NH3 at room temperature. The atomic hydrogen from dissociated ammonia reduces the NiF2 but it was determined that the atomic hydrogen from the ammonia does not react with SiO2.
