Ota-quadrotor: An Object-tracking Autonomous Quadrotor for Real-time Detection and Recognition
The field of robotics and mechatronics is advancing at an ever-increasing rate and we are starting to see robots making the transition from the factories to the workplace and homes as cost is reduced and they become more useful. In recent years quadrotors have become a popular unmanned air vehicle (UAV) platform. These UAVs or micro air vehicles (MAV) are being used for many new and exciting applications such as aerial monitoring of wildlife, disaster sites, riots and protests. They are also being used in the film industry, as they are significantly cheaper means of getting aerial footage. While quadrotors are not extremely expensive a good system can cost in the range of $3000 - $8000 and thus too costly as a research platform for many. There are a number of cheaper open source platforms. The ArduCopter is under constant development, has the largest community and is inexpensive making it an ideal platform to work with. The goal of this thesis was to implement video processing on a ground control station allowing for the ArduCopter to track moving objects. This was achieved by using the OpenCV video-processing library to implement object tracking and the MAVLink communication protocol, available on the ArduCopter platform, for communication.
The Otha Turner Family Picnic: Occupying Musical and Social Space In-Between Saturday Night and Sunday Morning
This thesis concerns African-American fife and drum band music, a pre-blues genre that was a fixture at summer picnics in the Mississippi hill country from the late nineteenth century through most of the twentieth century. The picnics held a unique place in African-American life, a crossroads of juke joints and churches, blues and gospel, individuality and family. Using the African-American paradigm of a Saturday night / Sunday morning people, I describe the Otha Turner Family Picnic, the last picnic to feature fife and drum band music, locating it and the music in-between the secular and sacred aspects of African-American life from both a musical and a social standpoint.
Out of Order
Out of Order is a documentary film that explores the emotional and physical aspects of living with polycystic ovarian syndrome. This reproductive disorder affects between 5 and 10% of all women of reproductive age. This film features an animated, autobiographical look at director Kimberly Davis' personal experience with this condition.
Overgeneral Memory and Posttraumatic Stress Disorder in Adults Exposed to Family Violence
Childhood exposure to familial violence increases risk for adult pathology, namely posttraumatic stress disorder (PTSD) and depression. Primary PTSD symptoms of hyperarousal and avoidance are implicated in overgeneral memory (OGM) theory in prior research. Individuals with trauma history tend to report OGMs, or non-specific autobiographical memories, perhaps to avoid unpleasant arousal elicited by recalling specific events. OGM, PTSD, depression, and arousal were assessed in adults with and without familial violence history. Arousal was measured via galvanic skin response (GSR) during an autobiographical memory task (AMT), requiring memory recall in response to emotionally-valenced cue words. Familial violence history was linked to higher incidence of PTSD symptoms. Childhood psychological violence was predictive of adult PTSD. Rates of depression, OGM, and arousal did not significantly vary by violence history. Significant gender differences were found relating to type of violence exposure and adult functioning. Research limitations, clinical implications, and future research suggestions are discussed.
Overview and Introduction to the Organ Music of Alsatian-american Composer René Louis Becker (1882-1956)
This dissertation provides the first biographical overview and annotated catalog of the organ music of Alsatian-American organist and composer René Louis Becker. Born and educated in Strasbourg, Alsace, Becker emigrated to the United States in 1904 and remained active as a composer and church musician for the next 50 years. in addition to providing sources for his biographical information, documentation of the specific organs with which Becker was professionally associated is included for the purpose of evaluating possible dates of composition of his undated organ works as well as for consideration of organ registrations when performing his works. Primary sources include newspaper clippings, personal correspondence, family scrapbooks, organ archives, and both published and unpublished manuscripts. Study of these manuscripts, including rediscovery of more than fifty works of Becker’s which were previously published in the early 1900s, present an opportunity to introduce a large new body of sophisticated repertoire from a distinguished and accomplished musician to the field of organ music. Becker composed more than 180 individual works for the organ, over half of which remain in manuscript and which were completely unknown since even before his death in 1956. Becker’s complete known oeuvre for organ includes 34 marches, 15 toccatas, three published large-scale sonatas as well as numerous works styled as preludes, postludes, finales, chansons, fantasies, fugues, and multiple small-scale compositions. After a brief biography and an overview of Becker’s compositional style and complete extant organ works, an introduction to his largest-scale work for the organ, the five-movement First Sonata in G, op. 40, is given. This is followed by an illustration of the overt stylistic influences present in the first two movements of that sonata with extensive musical examples, serving to establish Becker as one of the inheritors of the romantic tradition of the large-scale organ sonata and as a 20th century composer of note.
Parallels Between the Gaming Experience and Rosenblatt's Reader Response Theory
The world of literacy has expanded alongside technology, and new literacies are being used as an alternative or an addition to traditional text. By including video gaming as literacy, the connection can be made between students' multimodal world outside of school with the world of literacy they encounter in school. This study took two approaches of a content study and a case study. A collective case study was used to examine the gaming experience of participants with three commercial video games falling into three separate genres: Sims FreePlay (simulation); Halo 1 (first person shooter); and World of Warcraft (role playing game). The 15 gamers were placed into three sets of five participants for each video game, and interviews were conducted to explore the gaming experience in relation to stance and transaction, which are major components of Louise Rosenblatt's reader response theory. Limited research has been conducted regarding reader response theory and the new literacies; by using the reader response lens, the gaming experience was compared to the reading experience to add the new literacies to the existing literature on reader response. As a way to look at both the text and the experience, a content study examined three mainstream video games to establish literacy content by using Zimmerman's gaming literacy theory. Even though this theory is useful by detailing elements found in video games and not traditional literature, literary value cannot be fully assessed unless the theory is developed further to include other components or discuss how the depth of the components can relate to literary value. The literature does not currently contain substantial research regarding how to assess the literary value of video games, so this study begins to add to the present literature by demonstrating that at least for these games the presence of the components of the theory can be evaluated. This analysis of both the game and the experience demonstrated substantial parallels between the gaming experience and the reading transaction as well as looking at the viability of using gaming literacy theory to evaluate literacy value.
The Parent-Initiated Task Motivational Climate and Factors Influencing Eighth Grade Boys’ Intention to Continue Sports
The motivational climate, as defined by parents’ behaviors, and athletes’ goal orientations are essential in understanding children’s experiences with sport. The purpose of this study was to examine the perceived motivational climate created by parents, and its relationship to psychological outcomes experienced by adolescent male athletes in youth sports. In particular, the parent created task climate was examined through its influence on goal orientation and subsequently to psychological outcomes experienced in sport, specifically, sport competence, self-esteem, enjoyment, and intention to continue participating in sport. Participants were 405 8th grade male athletes (mean age = 13.5); (Sample A: n = 205; Sample B: n = 200). As expected, the task-oriented parent initiated motivational climate was associated with the boys’ mastery goal orientation. Participants with higher mastery goal orientation had greater sport competence, self-esteem, and more enjoyment in sport. Intention to continue playing sport was predicted primarily by their level of enjoyment, and secondarily by their increased feelings of self-esteem.
Parent Involvement and Science Achievement: A Latent Growth Curve Analysis
This study examined science achievement growth across elementary and middle school and parent school involvement using the Early Childhood Longitudinal Study – Kindergarten Class of 1998 – 1999 (ECLS-K). The ECLS-K is a nationally representative kindergarten cohort of students from public and private schools who attended full-day or half-day kindergarten class in 1998 – 1999. The present study’s sample (N = 8,070) was based on students that had a sampling weight available from the public-use data file. Students were assessed in science achievement at third, fifth, and eighth grades and parents of the students were surveyed at the same time points. Analyses using latent growth curve modeling with time invariant and varying covariates in an SEM framework revealed a positive relationship between science achievement and parent involvement at eighth grade. Furthermore, there were gender and racial/ethnic differences in parents’ school involvement as a predictor of science achievement. Findings indicated that students with lower initial science achievement scores had a faster rate of growth across time. The achievement gap between low and high achievers in earth, space and life sciences lessened from elementary to middle school. Parents’ involvement with school usually tapers off after elementary school, but due to parent school involvement being a significant predictor of eighth grade science achievement, later school involvement may need to be supported and better implemented in secondary schooling.
Parent Psychopathology, Marital Adjustment, and Child Psychological Dysfunction: The Mediating Role of Attachment and Sibling Relationship
This study is part of a larger research project examining family attachment processes. The current study tests a family process model that postulates the mediating role of parent-child attachment and sibling relationship quality in the associations of parent psychopathology or marital adjustment to children's psychological dysfunction. A community sample of 86 families with at least one school-aged (8-12 years) child was recruited from area schools and organizations. Families came to the UNT Family Attachment Lab, where they participated in research tasks, including interviews, self-report instruments, and videotaped interaction tasks. Specific questionnaires used in this study included the Sibling Relationship Questionnaire, the Security Scale, the Behavior Assessment System for Children, the Symptom Assessment-45 Questionnaire, and the Dyadic Adjustment Scale. Using a single indicator for each variable, path analyses tested three paternal models, three maternal models, and three systemic models using different informants' (i.e., father, mother, child) reports of child functioning as the outcome variable. Results of this study highlight the positive relationship between parent marital adjustment and parent-child attachment security, as well as the inverse relationship between maternal psychopathology and mother-child attachment security. In addition, the inverse relationship between parent-child attachment security and child psychological dysfunction was significant across nearly all paternal and maternal models. Particularly noteworthy was the consistent mediating influence of attachment security in the association between marital adjustment and child psychological dysfunction across paternal and maternal models.
Parent-Toddler Training: The Merits of Further Analysis
Earlier identification of autism allows for interventions to begin during toddlerhood. Literature suggests that parents are an important part of very early intervention and specific goals have indicated that they are important to progress. The use of telemedicine may increase access to interventions. The purpose of the study was to evaluate a parent-toddler training program that targeted social-communication skills and incorporated a telemedicine component. Measures included parent teaching targets, child attending, vocal requesting, and coordinated joint attention and the parent's response to coordinated joint attention. Results indicate that parent teaching increased, child attending and vocalizations increased, child coordinated joint attention increased, and the parent's response to coordinated joint attention was primarily social in nature. Analysis of the home observations indicates that direct in home observations or teleconference observations neither under or overestimated behaviors. The results are discussed in the context of teaching and feedback delivery and selection of teaching targets.
Parental Rights: Curriculum Opt-outs in Public Schools
The purposes of this dissertation were to determine the constitutional rights of parents to shield their children from exposure to parts of the public school curriculum that the parents find objectionable on religious, moral, or other grounds and to determine the statutory rights of parents to remove, or opt-out, their children from objectionable parts or all of the public school curriculum as set forth in the statutes of the 50 states and the District of Columbia. Many pivotal federal court cases dealing with parent rights and curricular issues, including Mozert v. Hawkins County Board of Education (1987), Vandiver v. Hardin County Board of Education (1987), Brown v. Hot, Sexy, & Safer Productions, Inc. (1995), Leebaert v. Harrington (2003), and Parker v. Hurley (2008) were surveyed using legal research methods. Specific types of curriculum opt-outs (e.g., sex education, comprehensive health programs, HIV/AIDS instruction) granted by each state were ascertained. States' statutes and regulations were categorized as non-existent, restrictive, or permissive based on the scope and breadth of each state's curriculum opt-out statute or regulation. A long list of federal court rulings have provided public schools the right to teach what school boards and administrators determine is appropriate. Parents did not have any constitutional right to opt their children out of public school curriculum. Many states' legislatures have granted parents a statutory right to opt their children out of certain parts of school curricula. In this study, 7 states had non-existent statutes or regulations, 18 states had restrictive statutes or regulations, and 26 states had permissive statutes or regulations.
Parents Of Children With High-functioning Autism: Experiences In Child-parent Relationship Therapy (Cprt)
This qualitative study attempted to capture the experiences of parents of children with high-functioning autistic spectrum disorders participating in child-parent relationship therapy (CPRT). Parents of children with high-functioning autistic spectrum disorders (HFASD) are prone to experiencing stress in the parent-child relationship due to difficulty in social understanding and rigid behavioral patterns often found among children with HFASD. Moreover, parents of children with HFASD may feel challenged to find suitable interventions that are time-limited, affordable, and appropriate for parents and children with HFASD. Because no research currently investigates the perceived acceptability of CPRT for parents of children with HFASD, it was decided that a qualitative study would best capture the experiences of parents of children with HFASD participating in CPRT to understand more fully whether CPRT is an appropriate intervention for these parents. Four parents and one grandparent were interviewed prior to and following their participation in 10 sessions of CPRT. Thematic analysis of the pre- and post-intervention interviews as well as the 10 CPRT sessions revealed eight themes related to the parents overall experience of CPRT and change in the parent, child, and parent-child relationship: understanding of CPRT concepts, reactions to CPRT, group dynamic, child characteristics, parent characteristics, knowledge and experiences with HFASD, family context, and parent-child relationship. The emerging themes indicated that the five participants found CPRT to be a useful intervention for developing skills to deal with child-behavior concerns related to HFASD. The participants also reported developing a better understanding of their children with HFASD and four parents reported increased closeness in the parent-child relationship. The implications for this research are that CPRT may offer parents of children with HFASD a time-limited intervention that meets their needs as parents, as well as possibly helping parents and children with HFASD develop increased closeness in the parent-child relationship.
Pasados Fragmentados:la Representación Teatral Del Robo De Niños En Las Dictaduras Española Y Argentina En Obras De Laila Ripoll Y Patricia Suárez
This study examines the theatrical representation of the stealing of children during the last dictatorships in Spain and in Argentina in Laila Ripoll's Los niños perdidos and Patricia Suárez's Astianacte: una máscara del amor under the lenses of the concepts of trauma, myth and memory. Following the theories suggested by Freud, Adorno, Whitehead, Reyes Mate and others, the first chapter discusses the representation of the psychological traumas left by the dictatorial practices left not only on the minds of individuals but also on both nations as whole entities. While Ripoll invites her audience to reflect upon the consequences of the Spanish Civil War and franquism, Patricia Suárez urges her spectators to doubt about their own identity if they were born during the last dictatorship in Argentina. In chapter two, the concepts advanced by Barthes, Reig Tapia and Moreno-Nuño help explore the ways in which the playwrights condemn the legitimizing myths that gave birth to these dictatorial regimes. Both authors subvert these fictional stories, mainly by the use of sarcasm and humor. By means of the concepts of memory supported by Benjamin, Todorov, Nora and Juliá, the third chapter examines the need to let the traditionally silenced voices tell their version of the historical events. Ripoll and Suárez warn their audiences that it is impossible to achieve one collective national memory because there are individual conflicting memories that stem from the personal experience of the traumatic events.
The Passage of the Comic Book to the Animated Film: The Case of the Smurfs
The purpose of this study is to explore the influence of history and culture on the passage of the comic book to the animated film. Although the comic book has both historical and cultural components, the latter often undergoes a cultural shift in the animation process. Using the Smurfs as a case study, this investigation first reviews existing literature pertaining to the comic book as an art form, the influence of history and culture on Smurf story plots, and the translation of the comic book into a moving picture. This study then utilizes authentic documents and interviews to analyze the perceptions of success and failure in the transformation of the Smurf comic book into animation: concluding that original meaning is often altered in the translation to meet the criteria of cultural relevance for the new audiences.
Patronage, Connoisseurship and Antiquarianism in Georgian England: The Fitzwilliam Music Collection (1763-1815)
In eighteenth-century Britain, many aristocrats studied music, participated as amateurs in musical clubs, and patronized London’s burgeoning concert life. Richard Fitzwilliam, Seventh Viscount Fitzwilliam of Merrion and Thorncastle (1745-1816), was one such patron and amateur. Fitzwilliam shaped his activities – participation, patronage, and collecting – in a unique way that illustrates his specialized tastes and interests. While as an amateur musician he sang in the Noblemen’s and Gentlemen’s Catch Club (the premiere social club dedicated to musical performance), he rose to the highest level of patronage by spearheading the Handel Commemoration Festival of 1784 and serving for many years as a Director of the Concert of Antient Music, the most prestigious concert series in Georgian Britain. His lasting legacy, however, was his bequest to Cambridge University of his extensive collection of art, books and music, as well as sufficient funds to establish the Fitzwilliam Museum. At the time of his death, Fitzwilliam’s collection of music was the best in the land, save that in the Royal Library. Thus, his collection is ideally suited for examination as proof of his activities, taste and connoisseurship. Moreover, the music in Fitzwilliam’s collection shows his participation in the contemporary musicological debate, evidenced by his advocacy for ancient music, his agreement with the views of Charles Avison and his support for the music of Domenico Scarlatti. On one side of this debate were proponents of learned, ancient music, such as Fitzwilliam and Avison, whose Essay on Musical Expression of 1752 was a milestone in musical criticism. On the other side of the discussion were advocates for the more modern, “classical” style and genres, led by historian Charles Burney.
A Pattern Oriented Data Structure for Interactive Computer Music
This essay describes a pattern oriented data structure, or PODS, as a system for storing computer music data. It organizes input by sequences or patterns that recur, while extensively interlinking the data. The interlinking process emulates cognitive models, while the pattern processing draws specifically from music cognition. The project aims at creating open source external objects for the Max/MSP software environment. The computer code for this project is in the C and Objective-C computer programming languages.
Patton's Iron Cavalry - The Impact of the Mechanized Cavalry on the U.S. Third Army
The American military experience in the European Theater of Operations during the Second World War is one of the most heavily documented topics in modern historiography. However, within this plethora of scholarship, very little has been written on the contributions of the United States Cavalry to this era. The six mechanized cavalry groups assigned to the Third Army served in a variety of roles, conducting screens, counter-reconnaissance, as well as a number of other associated security missions for their parent corps and the Army. Although unheralded, these groups made substantial and war-altering impacts for the Third Army.
Paul Hindemith's Septet (1948): A Look Back to Neue Sachlichkeit
In the early 1920s, Gustav Friedrich Hartlaub created a fine arts movement that began in Weimar, Germany, which questioned artistic Expressionism. In 1923, he formed an art exhibition to display new art works of simplicity that were of his anti-Expressionist goal. This exhibition was termed Neue Sachlichkeit, or New Objectivity, and quickly became associated with all fine arts. Music of Neue Sachlichkeit ideals during the 1920s and 1930s began to exhibit anti-Expressionist concepts of form, neoclassicism and limited instrumentation. Paul Hindemith was among the leading figures of Neue Sachlichkeit music. Although Paul Hindemith's Septet (1948) was composed during his later career, it shows many Neue Sachlichkeit traits found previously in the 1920s and 1930s. Characteristics of limited/mixed instrumentation, neoclassic instrumentation and form, and Baroque counterpoint are found in the Septet. These traits can also be head in earlier Neue Sachlichkeit pieces by Hindemith such as Hin und zuruck, op. 45a (1927), Das Marienleben (1922/23, rev. 1948) and Neues vom Tage (1929). Chapter 2 examines the Neue Sachlichkeit movement within the fine arts. Chapter 3 gives a brief biography of Paul Hindemith with a concentration on his influence of Neue Sachlichkeit music of the 1920s and 1930s. This chapter also relates this period of Hindemith's earlier career with his techniques used in later works, such as the Septet. Chapter 4 discusses how the Septet directly relates to the Neue Sachlichkeit fine arts movement. Chapter 5 gives a general analysis of the Septet. This analysis provides the reader with an understanding of the forms and tonal relationships used in the Septet. This summarizes the neoclassicism of the Septet and shows traits of Neue Sachlichkeit. Chapter 6 concludes with an examination of the mixed instrumentation of the Septet.
A Pedagogical and Analytical Study of Dušan Bogdanović’s Polyrhythmic and Polymetric Studies for Guitar
Polymeter has been a relatively unexplored compositional technique of music of the Common Practice Period. Dušan Bogdanović’s Polyrhythmic and Polymetric Studies for Guitar is recognized in the guitar world as not only an important theoretical treatise, but also a benchmark for more advanced levels of improvisation. Currently, his treatise remains the best source for learning polymetric improvisation on the guitar. My personal contribution stems from the idea that multiple interpretations of thought processes and technical approaches are possible when learning to play polymeters on the guitar. The first section focuses on providing an alternative technical approach towards learning to play polymeters on the guitar by simplifying selected exercises in Bogdanović’s treatise from their original presentation, and demonstrating further possibilities as to how the exercises can be applied in a practical manner to improvisation. The second part reveals through analysis of the Concert Studies 1, 2, and 5 both his innovative improvisatory use of polymeter as a stylistic device, and his ties to traditional ideas of structure.
Pediatric Feeding Disorders: A Controlled Comparison of Multidisciplinary Inpatient and Outpatient Treatment of Gastrostomy Tube Dependent Children
The efficacy of multidisciplinary inpatient and outpatient treatment for transitioning children with severe pediatric feeding disorders from gastrostomy tube dependency to oral nutrition was investigated utilizing caloric and fluid intakes as an outcome measure. The study involved 29 children ages 12 months to 5 years of age with gastrostomy tube dependency. Treatments were provided by speech therapists, occupational therapist, dietician and psychologist for a 30 day period. Four treatment groups were evaluated and average intakes compared at 4 observation periods including pretreatment, initiation of treatment, completion of treatment at 30 days and 4 month follow-up. Children receiving inpatient treatment for feeding disorders evidenced significant differences in oral caloric intake from pretreatment to discharge than outpatient treatment (p < .01) and wait list control group (p = .04). Oral caloric intake from discharge to 4 month follow up yielded no significant differences indicating treatment gains were maintained. Change in environment and caretaker showed a significant effect for the inpatient group (d = 1.89). Effects of treatment by age and weight at 4 month follow up were also analyzed.
The Peer Created Motivational Climate in Youth Sport and Its Relationship to Psychological Outcomes and Intention to Continue in Sport Among Male Adolescents
Social agents in the youth sport domain (coaches, parents, and peers) play a crucial role in developing the motivational approaches of youth sport athletes. One theory which has been useful in explaining the important role of such social agents has been Achievement Goal Theory (Nicholls, 1989). Specifically, Achievement Goal Theory was used to delineate various peer behaviors as being task-involving (Ntoumanis & Vazou, 2005) and was used to predict subsequent relationships relationship between the task-involving motivational-climate created by teammates and athletes’ mastery goal orientations and self-esteem, sport competence, enjoyment, and intention to continue playing sport. Participants were 405 boys aged 12-15 years. Using structural equation modeling, an exploratory analysis and confirmatory analysis revealed that higher levels of task-involving behaviors from peers predicted mastery goal orientation. Participants with higher mastery goal orientation reported greater sport competence, self-esteem, and more enjoyment; enjoyment was the strongest predictor of intention to continue. These findings both emphasize the importance of peer relationships within sport on a variety of motivationally and psychologically salient outcomes and provide direction for the development of training programs targeted to create positive and healthy sport experiences.
El Pensamiento de José Martí tergiversado como Ideología Política y de Lucha por la Revolución Cubana
The political ideologies that Martí envisioned of an America free from the inherited yoke of European ideals were taken by Fidel Castro as an anti-imperialist discourse. Therefore, Marti’s political vision on the power that the United States began to carry out at the end of the 19th century and the beginning of the 20th century was an excellent strategy to establish the anti-imperialist character of the Cuban revolution. Since 1961, Castro set Martí as the face of his Marxist-Leninist ideology to institute his anti-American philosophy; Castro created a myth of Marti’s persona, and converted him into the bastion of his political ideology. As a result, Castro distorted the revolutionary ideas of Marti’s. Castro proposed his ideas out of context and portrayed the incorrect idea of this great thinker and poet. Martí’s human ethic and love for the independence of Cuba placed Martí as a liberator of revolutionary and progressive ideas of his generation. Martí was not thought as a dictator and never was a man who lacked democratic values. The expressed analytical assimilation of Martí on his sociopolitical and economic juncture that was presented in America and Cuba was used to trace the political anti-imperialist propaganda by the dictatorial regime lead by Castro. This thesis will emphasize the persona of Jose Martí as a revolutionary, visionary and educator of his generation, then it will present the incorrect interpretation of Marti’s ideology by Fidel Castro, as an ideal to embark his revolution. Finally, the differences of his ideas in contrast to the political and social ideology of the Cuban revolution will be explained.
Perceived Effects of a Mid-length Study Abroad Program
The focus of the study was the University of Dallas’ Rome Program, a mid-length study abroad program on the university’s campus in Rome, Italy. The program is designed to provide participants with the opportunity to encounter firsthand Western tradition by integrating the core curriculum through classroom teachings and class excursions, thus solidifying the foundation of the participants’ undergraduate education. Beyond this purpose, the Rome Program does not operate from established goals and objectives for student experience. I consulted relevant research literature to construct a schema of domains of development appropriate to this qualitative study. These domains were intellectual development, global perspective, career development, and spiritual development. I interviewed 20 University of Dallas seniors who participated in the mid-length study abroad program between fall 2009 and spring 2011, using an extended, semi-structured interview protocol. The participants included 11 females and 9 males; 19 White and 1 Hispanic. The findings were supported by subsequent review by 4 of the interviewed students. I found generally strong but inconsistent support for student development in each of the domains. A number of sub-themes are reported. Through the interviews, an additional theme of personal development emerged and is reported. Although the findings generally support the conclusion that the Rome Program is successful, good education practice leads to a recommendation of more explicit setting of goals by higher education program planners and administrators. Such goal setting provides rationale for program construction, provides students with their own goal framework, and establishes a tangible framework for ongoing program evaluation.
The Perceived Value Among Employers of College Study Abroad for Engineers
Engineering graduates of the twenty-first century must be worldly and understand how to work with professionals from many cultures on projects that cross international boundaries. Increasingly, employers are finding that prospective employees who have studied abroad make better, more rounded candidates than those who have no life experience outside of their home region. The objective of this study was to determine whether engineering students who participate in a major-specific, study abroad experience are more desirable as candidates for employment than those who only study at their home institution. This descriptive study surveyed the membership of the combined Industrial Advisory Boards of the University of North Texas College of Engineering (n=90) which is a focused group of skilled managers and directors that represent various businesses, industries and organizations. The survey yielded a 58% response rate. The evaluation was validated by a survey that searched for a perceptual trend among representatives from business and industry who are in a hiring capacity for engineering graduates, evaluating a major-specific study abroad experience as part of a graduate’s employability and career growth. Statistical Analysis was made on Companies whose scope of business is domestic and international comparing the perceived value of study abroad as a characteristic for hiring new engineers, as well as comparing the perceived value of foreign study or work experience on the career development of engineers. These tests indicated that at the 0.05 level there was no statistical significance in the findings. Additional analysis was made on groups of employees that either had foreign experience (work or study) and those that did not. These tests indicated that there was no statistical significance in the findings. Analysis of the data indicates that although having a major specific study abroad experience may not be important at the entry level, it becomes more important as an engineer progresses into mid-career. It could also indicate change in the business climate and a growing need for global awareness. Additional observations show that other co-curricular activities, such as internships and grades weigh more in the hiring of a new engineering graduate.
Perception of Foreign Accented Speech: the Roles of Familiarity and Linguistic Training
This paper seeks to address the issue by examining two factors that potentially affect a listener’s perception of foreign accented speech: degree of familiarity (as acquired through a work or personal environment) and amount of ESL or linguistic training. Speech samples were recorded from 18 international students from Hispanic, Asian, and Middle-eastern backgrounds and across all proficiency levels as designated by their academic English program. Six native English speakers were also recorded to serve as a basis for comparison. Listeners were drawn from two pools: people with ESL and/or linguistic training (n=42) and laypersons with no such specialist training (n=36). After completing a background questionnaire to assess familiarity with foreign accented speech, each listener rated all 24 speech samples on the dimensions of comprehensibility, degree of accent, and communicative ability. Results indicate that participants with ESL/linguistic training rate foreign accented speech more positively on all three dimensions than laypersons with no such training. Additionally, degree of familiarity with foreign accented speech is positively correlated with how participants rated the accented speech samples. a number of highly significant interactions between these and other factors including sex of the speaker, proficiency level of the speaker, and L1 family of the speaker were found as well.
Perceptions of Control and Social Support: Correlates of HIV-Related Self-Efficacy
This study examines the extent to which locus of control and social support are linked to self-efficacy with regard to disease management in HIV-positive adults. Perceived ability to effectively manage illness was measured with the Self-Efficacy for Managing Chronic Disease Scale. Scores from the Multidimensional Scale of Perceived Social Support and the Multidimensional Locus of Control Scale were used as predictors. The gender-balanced sample (N = 69) of HIV+ adults was primarily African-American (65.3%) and European American (30.5%), with a mean age of 47 years (SD = 8.37). Correlational analyses suggested significant positive relationships between self-efficacy, social support, and locus of control due to powerful others. A regression analysis found that the model accounted for 23% of the variance in self-efficacy (adj. R-squared =.23, F (5, 63) = 4.81, p < .01), with social support (&#946; = .37, t = 3.28, p < .01) and locus of control (&#946; = .25, t = 2.26, p < .05) both significant predictors. Results suggest that social support and locus of control contribute to the belief that HIV can be managed. Interestingly, an external locus of control contributed to this belief, perhaps due to the perception of a physician, religious icon, or partner as a "powerful other." Results suggest that a strong supportive relationship with a trusted other along with enhanced social support typically associated with group-based interventions may improve health outcomes by increasing self-efficacy in disease management in HIV-positive adults.
Perceptions of Disaster Professionalism in Mexico: Adding a New Public Management Perspective to Emergency Management
This study investigated the perceptions of emergency managers regarding the degree of emergency management professionalism in Mexico and how it can be improved. The disaster of the Mexico City earthquake of 1985 was used as the starting point for this case study, as the prospects for more-frequent and more-intense disasters lend credence to the need for improved professionalism and, thus, effectiveness among emergency managers in the future. An expansive framework of emergency management professionalism mechanisms (or characteristics) and an additional compilation of new public management components (or values) were devised from the extant literatures found within the respective emergency management and public administration fields. The theory advanced by this study is that by integrating new public management components with emergency management mechanisms, professionalism in Mexico will improve and, thus, emergency managers will become more effective. ualitative field research was the methodology employed and it included interviews with 35 emergency managers in Mexico in corroboration with documentary evidence, to ascertain emergency managers' perceptions of professionalism in Mexico. The findings of this study determined that emergency managers in Mexico are implementing many of the mechanisms of professionalism but fewer new public management components. This study posits that by integrating new public management components with emergency management professionalism mechanisms, professionalism in Mexico will improve and will increase emergency managers' effectiveness.
A Performance Guide for Pearls I and Pearls II by Roland Szentpali
This dissertation is a performance guide for the euphonium solos Pearls I and Pearls II, written by Roland Szentpali. This performance guide allows performers to better understand the jazz styles within each movement and provides them with a resource for performing these particular pieces as well as other jazz influenced pieces. This performance guide is specific to euphonium repertoire and written for euphonium performers and educators. This is also a resource for a solo work in the repertoire that is performed regularly as well as a new work that will soon be published. A brief history of the development of euphonium repertoire and the influence of jazz is provided. The performance guide analyzes each movement and provides insight to extended techniques, common performance problems, errata, and jazz styles that each movement is based on. The guide also provides several suggestions for interpretation and for performance preparation. Illustrations from the scores have been provided for each example.
A Performance Guide to Bernd Alois Zimmermann's Trumpet Concerto, "Nobody Knows De Trouble I See"
Bernd Zimmermann's Trumpet Concerto, "Nobody Knows de Trouble I See" is an important twentieth-century work for trumpet. Despite the stature of the composition, it has rarely been performed due to its considerable musical and technical demands. Integrating these diverse demands into a coherent performance requires careful consideration of the various performance practice consequences. The study begins by exploring the historical and musical context in which the work was written. It then considers the individual musical elements of the concerto. Finally, the study examines the performance practice implications of the work. The performance guide serves as a framework for making intelligent musical and technical decisions through context, analysis, and practical considerations.
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.
Performance Practice of Interactive Music for Clarinet and Computer with an Examination of Five Works by American Composers
Since the development of interactive music software in the 1980s, a new genre of works for clarinet and computer has emerged. The rapid proliferation of interactive music resulted in a great deal of experimentation, creating a lack of standardization in both the composition and performance of this repertoire. In addition, many performers are reluctant to approach these works due to unfamiliarity with the genre and its technical and musical considerations. Performance practice commonly refers to interpretation of a written score, but the technology involved in interactive music requires a broader definition of performance practice; one that also addresses computer software, coordination between the performer and computer system, and technology such as microphones and pedals. The problems and potential solutions of interactive music performance practice are explored in this paper through review of the relevant published literature, interviews with experts in the field, and examination of musical examples from works for clarinet and computer by Lippe, May, Pinkston, Rowe, and Welch. Performance practice considerations of interactive music fall into the categories of notation, technology, collaboration, interpretation, and rehearsal. From the interviews and the literature, it is clear that the performance of interactive music requires specific knowledge and skills that performers may not encounter in other genres of contemporary music, including microphone technique, spatialization, sound processing, and improvisation. Performance practice issues are often mediated by close collaboration between performers and composers, but they can inhibit the accessibility of these works to new performers, and may be detrimental to the long-term viability of interactive music. Recommendations for resolving these issues are directed at both composers and performers of interactive music. A listing of over one hundred interactive works for clarinet and computer is also included.
Performance Rights in Sound Recordings: the Impact of the Performance Rights Act on Radio, Records, and Performing Artists
The original works of copyright holders included tangible creations, as music written on a page, thereby, extending copyright protection to songwriters and music publishers. Until 1995, absent from U.S. copyright law was protection for copyright owners of intangible sound recordings. the Performance Rights Act (PRA) seeks to amend the US copyright law in order to grant copyright holders of sound recordings the right to performance royalties from terrestrial broadcast radio. If passed, the legislation would be unprecedented in the United States. the PRA has implications for broadcast radio, record labels, and performing artists. This study includes historical and legal perspective of previous attempts at legislation of this nature and predicts outcomes of current legislation.
A Performer's Analysis of Dominick Argento's Miss Havisham's Wedding Night
Dominick Argento's Miss Havisham's Wedding Night is the least explored of his artistic output. A monodrama in one act for soprano, Miss Havisham's Wedding Night contains some of Argento's most beautiful and challenging music of his compositional output. The purpose of a detailed analysis of the structure and content of Argento's Miss Havisham's Wedding Night is to facilitate the solo vocal performer's interpretation. Argento's setting of Miss Havisham's Wedding Night is unique in that he musically translates the manic psychological state of the literary character. Argento structured the one act opera in such a manner that the music would illuminate the text and the audience might connect with the unstable psychological episodes and outbursts demonstrated by Miss Havisham. To that end, each section and phrase has its own psychological motivation, which in turn demands a varied musical and dramatic interpretation. Utilizing selected scenes from Miss Havisham's Wedding Night, the researcher will analyze Argento's musical manifestation of Dickens's literary work. This research will include an investigation into the manner in which Argento uses the shape of melody and the musical phrase along with the harmonic materials to enhance the text and dramatic content. The author will explore the musical nuances Argento incorporates in an effort to develop and portray Miss Havisham's psychological state. Through an analysis of the orchestral writing the author will show how Argento's aesthetic balance between the music and text represents the emotional and psychological implications of the monodrama.
A Performer's Guide to the First Two Movements of Pyotr Tchaikovsky's Grand Sonata in G Major, Opus 37
The Grand Sonata in G Major, Op.37, composed by Tchaikovsky, is a powerful large-scale composition and a piece of a symphonic scope. However, the sonata did not receive a desired acclaim in the modern repertoire partially due to an obvious lack of performance instructions in the existing editions, which makes the sonata challenging to perform. Thus, in order to reduce the technical challenges and to encourage more frequent performances of the sonata, this dissertation offers a performer's guide that addresses essential elements of pedal indications, phrasing and detailed dynamics, as well as suggestions on voice balancing, agogics, fingering, and hand redistribution. The guide consists of musical examples that are focused on the most challenging sections of the sonata, and is organized in the subsections according to a technique type proposed to facilitate a performance of the sonata. In addition to the examples on application of individual techniques presented in the main body of the dissertation, alternative and more elaborate versions of the suggestions are proposed in the appendices. The dissertation also provides a history of the sonata, and discusses its concept and symphonic principles. Additionally, the work highlights Tchaikovsky's piano style and describes his views on the art of piano performance. A special attention is also given to two musical references repeatedly embedded into the sonata: the bell-like sonorities and Dies irae melody.
Performing the “Classical”: the Gurukula System in Karnatic Music Society
Recent scholarship has revealed that the representation of Karnatic music as a “classical” art form in South Indian society was a complicated process bound to the agendas of larger early twentieth-century nationalist projects in India. This thesis explores the notions of classicalness as they are enacted in Karnatic music society through the oral transmission process from guru to shishya, or disciple. Still considered one of the most important emblems of the “classical,” the gurukula (lit. “guru-family”) system has been transformed to accommodate more contemporary lifestyles and reinscribed within many other social and musical processes in South Indian classical music society. This thesis examines the everyday interactions between members of Karnatic music society, particularly the clapping of t?la during a Karnatic music concert and the musical exchanges between percussionists onstage during the tani ?vartanam (Karnatic percussion solo), as public performances reminiscent of the relationship between guru and shishya.
Personalities and Pipelines: Exploring the Role of Personality in Student Self-selection Into Stem Majors
Despite all the national efforts to increase STEM enrollment in the United States, the gap between the U.S. and other developed countries in terms of STEM graduates has widened over the last 20 years. Researchers have studied factors such as gender, race, high school GPA, and the student’s socioeconomic status for their impact on STEM enrollment. This study offers another possible explanation of why students might choose, or not choose, to enroll in STEM majors by examining the relationship between personality and STEM enrollment. the sample included 2,745 respondents to the 2008 Cooperative Institutional Research Program freshman survey at a large research university in the southwestern United States. Factor analysis was used to create four personality scales, based on John Holland’s theory of personality types, with items selected from the survey. Logistic regression was utilized to answer three research questions: Are students classified as a strong investigative personality type more likely to enroll in STEM majors than students classified as a weak investigative personality type? Are there differences in their likelihood to enroll in STEM majors among students of investigative-social, investigative-artistic, and investigative-enterprising personality types? What effect does personality have on students’ self-selection into a biological versus a physical STEM major? Results suggested that students with a combined investigative and social personality were more likely to enroll in STEM majors whereas students with a combined investigative and artistic personality were less likely to do so. Additionally, STEM students with an enterprising personality were more likely to choose a biological STEM major than a physical STEM major. These results should benefit educators and policy makers who seek to strengthen the pipeline into STEM fields.
Personnel Preparation in Special Education: An Exploration of Autism Spectrum Disorders Programmatic Changes in Institutions of Higher Education Teacher Training Programs
Programmatic change related to autism spectrum disorders (ASD) training in special education teacher education programs across the U.S. and institutional variables that influenced change were examined. Variables included institutions’ current coverage of autism content in coursework and institution enrollment. One faculty member from each identified institution was invited to participate in the study. Data were collected from 136 special education faculty using an exploratory survey instrument, the National Survey on ASD Preparation in Undergraduate Special Education Teacher Training Programs (NSAP). This study was designed around themes which emerged from empirical and pragmatic research findings conceptualizing prevalent issues in personnel preparation for ASD including critical knowledge and skills needed by teachers to effectively serve students with ASD. Results indicated a significant number of programmatic changes (66%) remain to be implemented in undergraduate special education programs at institutions participating in the study.
Perspectives on Cultural Context: The Use of an Online Participatory Learning Environment as an Expansion of the Museum Visit
Technology offers opportunities for museums to expand the ways in which cultural perspectives relevant to objects on display can be exchanged and understood. Multimedia content offered online in an environment with user input capabilities can encourage dialogue and enrich visitor experiences of museums. This action research project using narrative analysis was an effort to develop the use of web technology in museum education practice, with an emphasis on constructivist learning. Concepts including the visitor-centered museum and multiple narratives led the researcher to collaborate with a pre-service art teacher education classroom and a local Hindu community to create content that might better develop understandings of one museum's Hindu sculpture collection that are personal, cultural, and complex.
Phase Separation and Second Phase Precipitation in Beta Titanium Alloys
The current understanding of the atomic scale phenomenon associated with the influence of beta phase instabilities on the evolution of microstructure in titanium alloys is limited due to their complex nature. Such beta phase instabilities include phase separation and precipitation of nano-scale omega and alpha phases in the beta matrix. The initial part of the present study focuses on omega precipitation within the beta matrix of model binary titanium molybdenum (Ti-Mo) alloys. Direct atomic scale observation of pre-transition omega-like embryos in quenched alloys, using aberration-corrected high resolution scanning transmission electron microscopy and atom probe tomography (APT) was compared and contrasted with the results of first principles computations performed using the Vienna ab initio simulation package (VASP) to present a novel mechanism of these special class of phase transformation. Thereafter the beta phase separation and subsequent alpha phase nucleation in a Ti-Mo-Al ternary alloy was investigated by coupling in-situ high energy synchrotron x-ray diffraction with ex-situ characterization studies performed using aberration corrected transmission electron microscopy and APT to develop a deeper understanding of the mechanism of transformation. Subsequently the formation of the omega phase in the presence of simultaneous development of compositional phase separation within the beta matrix phase of a Ti-10V-6Cu (wt%) alloy during continuous cooling has been investigated using a combination of transmission electron microscopy and atom probe tomography. The results of these investigations provided novel insights into the mechanisms of solid-state transformations in metallic systems by capturing the earliest stages of nucleation at atomic to near atomic spatial and compositional resolution.
Photoactivatable Quantum Dots in Super-Resolution Microscopy of Muscle
Super-resolution 3D imaging was achieved using newly synthesized photoactivatable quantum dot (PAQ dot) probes. Quantum dots were modified with a novel quencher system to make them photoactivatable. The unique properties of these PAQ dots enable single-fluorophore localization in three dimensions using a confocal microscopy optical sectioning method. Myosin and tropomyosin of rabbit myofibrilar bundles were specifically labeled with the newly synthesized PAQ dot. A sufficient number of single quantum dots were photoactivated, localized and reduced to their centroid and then reconstructed to a super-resolution image. The acquired super-resolution image shows a lateral and an axial sub-diffraction resolution and demonstrates ultrafine striations with widths less than 70 nm that are not evident by conventional confocal microscopy. The striations appear to be related to nebulin thin filament binding protein. This newly developed imaging system is cutting edge for its high resolution and localization as well its simplicity and convenience.
Photophysics and Photochemistry of Copper(I) Phosphine and Collidine Complexes: An Experimental/Theoretical Investigation
Copper(I) complexes have been studied through both experimental and computational means in the presented work. Overall, the work focuses on photophysical and photochemical properties of copper(I) complexes. Photophysical and photochemical properties are found to be dependent on the geometries of the copper(I) complexes. One of the geometric properties that are important for both photochemical and photophysical properties is coordination number. Coordination numbers have been observed to be dependent on both ligand size and recrystallization conditions. The complexes geometric structure, as well as the electronic effects of the coordination ligands, is shown both computationally as well as experimentally to affect the emission energies. Two-coordinate complexes are seen to have only weak emission at liquid nitrogen temperature (77 K), while at room temperature (298 K) the two-coordinate complexes are not observed to be luminescent. Three-coordinate complexes are observed to be luminescent at liquid nitrogen temperature as well as at room temperature. The three-coordinate complexes have a Y-shaped ground (S0) state that distorts towards a T-shape upon photoexcitation to the lowest lying phosphorescent state (T1). The geometric distortion is tunable by size of the coordinating ligand. Luminescence is controllable by limiting the amount of non-radiative emission. One manner by which non-radiative emission is controlled is the amount of geometric distortion that occurs as the complex undergoes photoexcitation. Bulky ligands allow for less distortion than smaller ligands, leading to higher emission energies (blue shifted energies) with higher quantum efficiency. Tuning emission and increasing quantum efficiencies can be used to create highly efficient, white emitting materials for use in white OLEDS.
Physical-Layer Network Coding for MIMO Systems
The future wireless communication systems are required to meet the growing demands of reliability, bandwidth capacity, and mobility. However, as corruptions such as fading effects, thermal noise, are present in the channel, the occurrence of errors is unavoidable. Motivated by this, the work in this dissertation attempts to improve the system performance by way of exploiting schemes which statistically reduce the error rate, and in turn boost the system throughput. The network can be studied using a simplified model, the two-way relay channel, where two parties exchange messages via the assistance of a relay in between. In such scenarios, this dissertation performs theoretical analysis of the system, and derives closed-form and upper bound expressions of the error probability. These theoretical measurements are potentially helpful references for the practical system design. Additionally, several novel transmission methods including block relaying, permutation modulations for the physical-layer network coding, are proposed and discussed. Numerical simulation results are presented to support the validity of the conclusions.
Piano-related Musculoskeletal Disorders: Posture and Pain
A healthy posture protects the body-supporting functions and prevents injuries by maintaining balance. Literature in performing arts medicine suggests that posture is an important component to prevent piano-playing related injuries. However, no known research studies have quantified, characterized, and compared pianists' sitting postures. The purpose of this study was to explore the relationship between playing postures and perceived pain among pianists. This study applied innovative approach using qualitative and quantitative methods, combined with three-dimensional motion captured technology. To examine risk factors related pianists' postures, three-dimensional motion-capture cameras recorded approximate 40 pianists' postures in various situations; data recordings were combined with a statistical method to investigate pain-posture correlations. Results reveal that the degrees of head-neck or body tilt angles are the tendency of risk factors for piano-playing related pain. Results from this study may have multiple practical implications among which are: (1) a risk factor pain, injury index, or indicator (2) a performance habits profile and (3) practice guide to prevention of piano-playing related musculoskeletal disorders.
Piezoresistive Polyvinylidene Fluoride/Carbon Filled Nanocomposites
This thesis examines the value of using dispersed conductive fillers as a stress/strain sensing material. The effect of the intrinsic conductivity of the filler on the ability to be effective and the influence of filler concentration on the conductivity are also examined. To meet these objectives, nanocomposites of polyvinylidene fluoride (PVDF) with carbon nanofibers (CNFs) and carbon nanotubes (CNTs) were prepared by melt-blending using a twin screw extruder. Since PVDF has a potential to be piezoresistive based on the type of crystalline phase, the effect of CNFs on PVDF crystallinity, crystalline phase, quasi static and dynamic mechanical property was studied concurrently with piezoresponse. Three time dependencies were examined for PVDF/CNTs nanocomposites: quasi-static, transient and cyclic fatigue. The transient response of the strain with time showed viscoelastic behavior and was modeled by the 4-element Burger model. Under quasi-static loading the resistance showed negative pressure coefficient below yield but changed to a positive pressure coefficient after yield. Under cyclic load, the stress-time and resistance-time were synchronous but the resistance peak value decreased with increasing cycles, which was attributed to charge storage in the nanocomposite. The outcomes of this thesis indicate that a new piezoresponsive system based on filled polymers is a viable technology for structural health monitoring.
Pilot of a Learning Management System to Enhance Counselors' Relational Qualities Through Mindfulness-based Practices
Mindfulness-based practices are associated with increased attentional qualities, improved self-focus styles, enhanced empathic understanding, and strengthened self-compassion, making these practices a viable addition to counselor training programs. However, current mindfulness training models are primarily designed for relief of psychological distress, stress reduction, and increased well-being rather than focused on enhancing therapeutic skills and require intensive time commitments that may present logistical difficulties for overburdened curricula and graduate students. This study piloted an on-line, eight-week mindfulness-based practices learning management system for counselors (MBLMS-C) with a specific focus on the cultivation of qualities associated with successful therapeutic relationships. Ten of forty-six recruited counseling master's students enrolled in their first basic skills course at a sample of accredited universities across the United States completed the exit survey. Data were analyzed using multivariate repeated measures analyses comparing pre- post- counselor relational qualities of mindfulness traits, empathy, self-focus style, and self-compassion. Results indicated no statistically significant difference with a partial ?2 = .73. What-if analyses (N = 30) indicated statistical significance may have been obtained given a larger sample. Variance was explained by increased self-compassion (partial ?2 = .34) and mindfulness traits (partial ?2 = .31) and decreased self-focus style rumination (partial ?2 = .23) and empathic personal distress (partial ?2 = .12). Changes were observed in the desired direction for self-focus style reflection and empathic perspective taking/empathic concern. Discussion includes a review of the findings including examination of participant feedback regarding training experience. Study limitations and implications for counselor education, professional enhancement, and suggestions for future research are also offered.
Piracy on the Ground: How Informal Media Distribution and Access Influences Cultures in Contemporary Hanoi, Viet Nam
This thesis explores how pirate cultures and “informal” distribution circuits operate on the ground level and integrate global media texts (mainly Hollywood films) into a small section of the local everyday society of Hanoi, Viet Nam. Situating the pirate stores and its components as active and central, this thesis will examine the physical flow of media through these store sites. In addition, by exploring the interactions between media texts, store owners and workers, customers, and the store’s design itself, this thesis will reveal how media piracy (as a form of distribution and “normal” access) influences and negotiates modernity, cultures, identities, and meanings in Hanoi and Viet Nam.
Podcast Effectiveness as Scaffolding Support for Students Enrolled in First-Semester General Chemistry Laboratories
Podcasts covering essential first-semester general chemistry laboratory techniques and central concepts that aid in experimental design or data processing were prepared and made available for students to access on an as-needed basis on iPhones- or iPod touches-. Research focused in three areas: the extent of podcast usage, the numbers and types of interactions between instructors and research teams, and student performance on graded assignments. Data analysis indicates that the podcast treatment research teams accessed a podcast 2.86 times on average during each week that podcasts were available. Comparison of interaction data for the lecture treatment research teams and podcast treatment research teams reveals that interactions with instructors were statistically significantly fewer for teams that had podcast access rather than a pre&#8208;laboratory lecture. The implication of the results is that student research teams were able to gather laboratory information more effectively when it was presented in an on-demand podcast format. Finally, statistical analysis of data on student performance on graded assignments indicates no significant differences between outcome measures for the treatment groups when compared as cohorts. The only statistically significant difference is between students judged to be highly motivated; for this sub&#8208;group the students in the podcast treatment group earned a course average that was statistically significantly higher than those in the lecture treatment group. This research study provides some of the first data collected on the effectiveness of podcasts delivered as needed in a first-semester general chemistry laboratory setting.
Podcasting in an Eighth-Grade American History Class
The purpose of this study was to see how students used podcasts in an eighth-grade American history unit and the value they placed on them as an educational tool. The 6-week study was conducted in a suburban middle school in a district that is part of a large metropolitan area in Texas. Participants included 29 students and 2 eighth-grade teachers. The research questions were the following: (1) How do students use podcasts in an eighth-grade American history class? (2) How do students perceive the impact of the podcasts on their overall learning of the subject material? and (3) Do the podcasts motivate the students to study? Quantitative data were collected through a Likert-scaled student survey and logs kept by students. Qualitative data were collected through an open-ended portion of the student survey, student focus group discussion, and a faculty interview. The treatment tools were audio podcasts in the form of vocabulary-quiz reviews, historical vignettes, lectures, and a unit test review—all on the topic of the American Revolution. The data indicated that the students primarily used their computers at home to listen to the podcasts as they prepared for quizzes and/or the unit test. The students believed that the podcasts had a positive impact upon their grade, were a positive educational tool, and helped them to better understand the material at hand. The students also wanted to see an expansion of podcast usage in other subjects. The students claimed that it motivated them to study and the participating teachers agreed that it motivated the students to study in a non-traditional manner. Data illustrated a need for further research regarding podcasting’s impact on grades and performance at the K-12 level, student podcast construction, podcast delivery modes, and podcast use with special education and ELL students.
The Political Determinants of Fdi Location in Prchina, 1997-2009: Application of a New Model to Taiwanese Fdi in Mainland China
This research seeks to identify the political determinants that account for the uneven geographical distribution of foreign direct investment (FDI) across Chinese counties. I compare the political determinants of Taiwanese FDI (TDI) and non-Taiwanese FDI site selection across counties in China. I focus on the central-local politics in China, especially the effect of county government autonomy on FDI and TDI site selection. I investigate whether the effect of county government autonomy and its interaction with TDI agglomeration varies across the three economic regions of China (i.e. eastern, central, and western regions). I argue that county government autonomy is critical to attracting inflows of FDI, and its impact is conditional on the existing level of FDI in a given county. Counties with higher autonomy are able to make greater commitments to and involvement in the market economy, have more flexibility to give preferential treatment to FDI and to improve the local investment environment. With the political burden that Taiwanese investors face from the special military and political relationship across the Strait, I argue that TDI is more sensitive to county government autonomy not only for the economic gains like other foreign investors but also for pursuing local protection against the political uncertainties from Beijing and the social instabilities of the local population. I also argue that county government autonomy’s impact on TDI inflow is strongest in the central region due to the less dominating role of the geographic and cultural advantages enjoyed by the eastern region and its better economic, cultural, political and geographic conditions that are lacking in the western region. Using the System General Method of Moment model to analyze the county level FDI/TDI panel data sets, I find autonomy’s impact on future FDI inflows fades with the increases in the existing level of FDI but gets stronger with the increases in the existing level of TDI inflows. I also find county government autonomy’s impact is strongest for the central region when the existing TDI inflows are zero or at the national average level.
Political Identity of First-Year College Students: An Analysis of Student Characteristics Using Cooperative Institutional Research Program (CIRP) Data
This quantitative study utilized secondary self-reported data from the 2008 administration of the Cooperative Institutional Research Program (CIRP) Freshman Survey from two Texas public universities to investigate the pre-college demographic, academic, attitude, behavioral, and familial factors that may relate to students' self-reported political identities. The study design was correlational regarding the relationship of the demographic, academic, attitude, behavioral, and familial independent variables to the dependent variable of the students' political identities. ANOVA main effects for the independent variables were calculated, and statistical significance required the p < .05 level. The statistically significant demographic factors were native English-speaking status; enrollment status; citizenship status; religious preference; and race. The statistically significant academic factor was intended major. The statistically significant attitude factors were opinions regarding social issues such as criminal rights; abortion rights; the death penalty; the legalization of marijuana; homosexual relationships and same-sex marriage; racial discrimination; income taxes; affirmative action; military spending and voluntary military service; gun control; the environment; national health care; immigration; personal success; political dissent; and free speech. Other statistically significant attitude factors related to personal goals of making artistic and scientific contributions; being politically influential and politically knowledgeable; raising a family; participating in environmental programs and community action programs; developing a life purpose; promoting racial understanding; and promoting cultural understanding. The statistically significant behavioral factors were the frequency with which students participated in activities such as attending religious services; smoking; feeling overwhelmed or depressed; playing a musical instrument; discussing politics; and being involved in political campaigns. Other statistically significant behavioral factors were the frequency with which students participated in critical thinking activities such as using logical arguments to support their opinions; seeking alternative solutions to problems; researching scientific articles; exploring topics of personal interest; and accepting mistakes. The statistically significant familial factors were the religious preferences of the students' fathers and mothers. The results can give insight into the political characteristics of the students with whom student affairs professionals work. They can be used to inform the planning and implementation of educational programs that aid in students' political identity development.
