Bayesian Probabilistic Reasoning Applied to Mathematical Epidemiology for Predictive Spatiotemporal Analysis of Infectious Diseases

Description: Abstract Probabilistic reasoning under uncertainty suits well to analysis of disease dynamics. The stochastic nature of disease progression is modeled by applying the principles of Bayesian learning. Bayesian learning predicts the disease progression, including prevalence and incidence, for a geographic region and demographic composition. Public health resources, prioritized by the order of risk levels of the population, will efficiently minimize the disease spread and curtail the epidemic at the earliest. A Bayesian network representing the outbreak of influenza and pneumonia in a geographic region is ported to a newer region with different demographic composition. Upon analysis for the newer region, the corresponding prevalence of influenza and pneumonia among the different demographic subgroups is inferred for the newer region. Bayesian reasoning coupled with disease timeline is used to reverse engineer an influenza outbreak for a given geographic and demographic setting. The temporal flow of the epidemic among the different sections of the population is analyzed to identify the corresponding risk levels. In comparison to spread vaccination, prioritizing the limited vaccination resources to the higher risk groups results in relatively lower influenza prevalence. HIV incidence in Texas from 1989-2002 is analyzed using demographic based epidemic curves. Dynamic Bayesian networks are integrated with probability distributions of HIV surveillance data coupled with the census population data to estimate the proportion of HIV incidence among the different demographic subgroups. Demographic based risk analysis lends to observation of varied spectrum of HIV risk among the different demographic subgroups. A methodology using hidden Markov models is introduced that enables to investigate the impact of social behavioral interactions in the incidence and prevalence of infectious diseases. The methodology is presented in the context of simulated disease outbreak data for influenza. Probabilistic reasoning analysis enhances the understanding of disease progression in order to identify the critical points of surveillance, ...

VLSI Architecture and FPGA Prototyping of a Secure Digital Camera for Biometric Application

Description: This thesis presents a secure digital camera (SDC) that inserts biometric data into images found in forms of identification such as the newly proposed electronic passport. However, putting biometric data in passports makes the data vulnerable for theft, causing privacy related issues. An effective solution to combating unauthorized access such as skimming (obtaining data from the passport's owner who did not willingly submit the data) or eavesdropping (intercepting information as it moves from the chip to the reader) could be judicious use of watermarking and encryption at the source end of the biometric process in hardware like digital camera or scanners etc. To address such issues, a novel approach and its architecture in the framework of a digital camera, conceptualized as an SDC is presented. The SDC inserts biometric data into passport image with the aid of watermarking and encryption processes. The VLSI (very large scale integration) architecture of the functional units of the SDC such as watermarking and encryption unit is presented. The result of the hardware implementation of Rijndael advanced encryption standard (AES) and a discrete cosine transform (DCT) based visible and invisible watermarking algorithm is presented. The prototype chip can carry out simultaneous encryption and watermarking, which to our knowledge is the first of its kind. The encryption unit has a throughput of 500 Mbit/s and the visible and invisible watermarking unit has a max frequency of 96.31 MHz and 256 MHz respectively.

An analysis of the Sonata for Trumpet and Piano by Peter Maxwell Davies, identifying the use of historical forms, and the implications for performance.

Description: The Sonata for Trumpet and Piano by Peter Maxwell Davies is one of his earliest works, and a notoriously difficult work to perform. While using serialism and other twentieth-century compositional techniques, this work also uses older historical forms, including sonata-allegro and sonata-rondo forms. An analysis of the work is presented, identifying the older historical forms, and considerations for performers when making decisions on how to perform the work are provided.

Athletic Trainers and Psychological Disorders Among Athletes: An Examination of Their Abilities to Recognize, Diagnose and Intervene.

Description: Utilizing an analogue research design conducted via the Internet, this study assessed athletic trainers' abilities to recognize, diagnose, and intervene with a hypothetical athlete experiencing depression, and examined the impact of their gender, athlete gender, and athlete's presenting problem on their decisions. Athletic trainers' perceived competency in using psychosocial interventions with athletes, history of referring athletes to psychology professionals, and training backgrounds in psychology also were examined. Participants (270 male and 370 female certified athletic trainers) were randomly assigned to one of six conditions (Athlete Gender X Presenting Problem). After reading the appropriate vignette, they completed questions related to the athlete's psychological symptoms and diagnosis, referral recommendations, and use of psychosocial interventions if working with the athlete. The vignettes were identical except for the athlete's gender and problem. Overall, athletic trainers accurately identified the athlete's depressive symptoms/diagnosis and need for psychological referral. They rated the athlete significantly higher in Depressive Symptoms than in Anger/Agitation Symptoms and Compulsive Behavioral Symptoms, and as more likely to be experiencing a depressive disorder compared to an adjustment disorder, anxiety disorder, sleep disorder, or substance abuse disorder. Female athletic trainers provided significantly higher ratings of Depressive Symptoms than males and the injured athlete was rated significantly higher in Anger/Agitation than the performance problem athlete. Diagnosis ratings were not influenced by athlete gender, athletic trainer gender, or type of problem. Athletic trainers were most likely to refer the athlete to a psychology professional compared to an allied health professional, treating the athlete themselves, or doing nothing. Presenting problem significantly impacted referral recommendations. If treating the athlete themselves, athletic trainers were significantly more likely to use supportive interventions than cognitive-behavioral techniques; they felt significantly more competent in providing supportive interventions. Competency in both interventions was significantly enhanced if athletic trainers completed psychology coursework. Findings suggest that athletic ...

Comparison and Evaluation of Existing Analog Circuit Simulator using Sigma-Delta Modulator

Description: In the world of VLSI (very large scale integration) technology, there are many different types of circuit simulators that are used to design and predict the circuit behavior before actual fabrication of the circuit. In this thesis, I compared and evaluated existing circuit simulators by considering standard benchmark circuits. The circuit simulators which I evaluated and explored are Ngspice, Tclspice, Winspice (open source) and Spectre® (commercial). I also tested standard benchmarks using these circuit simulators and compared their outputs. The simulators are evaluated using design metrics in order to quantify their performance and identify efficient circuit simulators. In addition, I designed a sigma-delta modulator and its individual components using the analog behavioral language Verilog-A. Initially, I performed simulations of individual components of the sigma-delta modulator and later of the whole system. Finally, CMOS (complementary metal-oxide semiconductor) transistor-level circuits were designed for the differential amplifier, operational amplifier and comparator of the modulator.

Generic Algebras and Kazhdan-Lusztig Theory for Monomial Groups

Description: The Iwahori-Hecke algebras of Coxeter groups play a central role in the study of representations of semisimple Lie-type groups. An important tool is the combinatorial approach to representations of Iwahori-Hecke algebras introduced by Kazhdan and Lusztig in 1979. In this dissertation, I discuss a generalization of the Iwahori-Hecke algebra of the symmetric group that is instead based on the complex reflection group G(r,1,n). Using the analogues of Kazhdan and Lusztig's R-polynomials, I show that this algebra determines a partial order on G(r,1,n) that generalizes the Chevalley-Bruhat order on the symmetric group. I also consider possible analogues of Kazhdan-Lusztig polynomials.

The Adoption and Use of Electronic Information Resources by a Non-Traditional User Group: Automotive Service Technicians.

Description: The growing complexity of machines has led to a concomitant increase in the amount and complexity of the information needed by those charged with servicing them. This, in turn, has led to a need for more robust methods for storing and distributing information and for a workforce more sophisticated in its use of information resources. As a result, the service trades have "professionalized," adopting more rigorous academic standards and developing ongoing certification programs. The current paper deals with the acceptance of advanced electronic information technology by skilled service personnel, specifically, automotive service technicians. The theoretical basis of the study is Davis' technology acceptance model. The purpose of the study is to determine the effects of three external factors on the operation of the model: age, work experience, and education/certification level. The research design is in two parts, beginning with an onsite observation and interviews to establish the environment. During the second part of the research process a survey was administered to a sample of automotive service technicians. Results indicated significant inverse relationships between age and acceptance and between experience and acceptance. A significant positive relationship was shown between education, particularly certification, and acceptance.

An Integrated Architecture for Ad Hoc Grids

Description: Extensive research has been conducted by the grid community to enable large-scale collaborations in pre-configured environments. grid collaborations can vary in scale and motivation resulting in a coarse classification of grids: national grid, project grid, enterprise grid, and volunteer grid. Despite the differences in scope and scale, all the traditional grids in practice share some common assumptions. They support mutually collaborative communities, adopt a centralized control for membership, and assume a well-defined non-changing collaboration. To support grid applications that do not confirm to these assumptions, we propose the concept of ad hoc grids. In the context of this research, we propose a novel architecture for ad hoc grids that integrates a suite of component frameworks. Specifically, our architecture combines the community management framework, security framework, abstraction framework, quality of service framework, and reputation framework. The overarching objective of our integrated architecture is to support a variety of grid applications in a self-controlled fashion with the help of a self-organizing ad hoc community. We introduce mechanisms in our architecture that successfully isolates malicious elements from the community, inherently improving the quality of grid services and extracting deterministic quality assurances from the underlying infrastructure. We also emphasize on the technology-independence of our architecture, thereby offering the requisite platform for technology interoperability. The feasibility of the proposed architecture is verified with a high-quality ad hoc grid implementation. Additionally, we have analyzed the performance and behavior of ad hoc grids with respect to several control parameters.

Functional Ontology Construction: A Pragmatic Approach to Addressing Problems Concerning the Individual and the Informing Environment

Description: Functional ontology construction (FOC) is an approach for modeling the relationships between a user and the informing environment by means of analysis of the user's behavior and the elements of the environment that have behavioral function. The FOC approach is an application of behavior analytic techniques and concepts to problems within information science. The FOC approach is both an alternative and a compliment to the cognitive viewpoint commonly found in models of behavior in information science. The basis for the synthesis of behavior analysis and information science is a shared tradition of pragmatism between the fields. The application of behavior analytic concepts brings with it the notion of selection by consequence. Selection is examined on the biological, behavioral, and cultural levels. Two perspicuous examples of the application of the FOC modeling approach are included. The first example looks at the document functioning as a reinforcer in a human operant experimental setting. The second example is an examination of the verbal behavior of expert film analyst, Raymond Bellour, the structure of a film he analyzed, and the elements of the film's structure that had behavioral function for Bellour. The FOC approach is examined within the ontological space of information science.

Resource Management in Wireless Networks

Description: A local call admission control (CAC) algorithm for third generation wireless networks was designed and implemented, which allows for the simulation of network throughput for different spreading factors and various mobility scenarios. A global CAC algorithm is also implemented and used as a benchmark since it is inherently optimized; it yields the best possible performance but has an intensive computational complexity. Optimized local CAC algorithm achieves similar performance as global CAC algorithm at a fraction of the computational cost. Design of a dynamic channel assignment algorithm for IEEE 802.11 wireless systems is also presented. Channels are assigned dynamically depending on the minimal interference generated by the neighboring access points on a reference access point. Analysis of dynamic channel assignment algorithm shows an improvement by a factor of 4 over the default settings of having all access points use the same channel, resulting significantly higher network throughput.

The Influence of Fredrik Melius Christiansen on Six Minnesota Conductor-Composers

Description: F. Melius Christiansen was very influential in the a cappella choral tradition. He started his career in Norway and brought his expertise to the American Midwest. Christiansen established a name for himself while working at St. Olaf Lutheran College as the head of the music department. It was the blended choral sound and precision he was able to achieve and display with his new choir in 1912 that caught everyone's ear. He continued to succeed with national and international tours, allowing him to spread his new "St. Olaf" choral sound through his music, compositions, and conducting school. This study explores the influence of F. Melius Christiansen (1871-1955) and the Minnesota choral tradition on six subsequent conductor-composers' compositions and conducting styles, including: Olaf Christiansen (1901-1984), Paul J. Christiansen (1914-1997), Kenneth Jennings (b. 1925), Robert Scholz (b. 1940), René Clausen (b. 1953), and Kenneth Hodgson (b. 1939) using Schenkerian analysis.

Current Practices in Working With Special Education Paraeducators.

Description: With so many paraeducators working in special education, it is important for teachers, administrators, and researchers to know how paraeducators are being utilized, supervised, and managed in order to create the most effective programs for students with special needs. Research is needed regarding current practices in supervising paraeducators. The purposes of this study were to (a) delineate the current practices being utilized by special education teachers of students with emotional and behavioral disorders (EBD) who supervise paraeducators that work with students with EBD in the general education classroom and (b) determine how effective the supervised paraeducators perceive those practices to be. Current practices were revealed by answering the following questions: (1) According to special education teachers and paraeducators, what procedures and practices are being utilized to supervise paraeducators who work in the general education environment with students with EBD? (2) In what ways do teachers and paraeducators see these supervision practices as being effective? (3) What is the relationship between actual supervision practices and accepted best practices? There were 60 participants in all, 30 professional teachers and 30 paraeducators. All 60 participants completed a survey; of these 60, 5 teachers and 5 paraeducators were individually interviewed Findings from the study indicate that actual supervision practices of teachers do not represent the best practices found in the literature. The study found that each of the seven executive functions of supervision (orientation, planning, scheduling, delegating, training/coaching, monitoring/feedback, and managing the workplace) need additional attention from school districts in order to maximize paraeducator effectiveness.

Regulation of pyrimidine biosynthesis and virulence factor production in wild type, Pyr- and Crc- mutants in Pseudomonas aeruginosa.

Description: Previous research in our laboratory established that pyrB, pyrC or pyrD knock-out mutants in Pseudomonas aeruginosa required pyrimidines for growth. Each mutant was also discovered to be defective in the production of virulence factors. Moreover, the addition of exogenous uracil did not restore the mutant to wild type virulence levels. In an earlier study using non-pathogenic P. putida, mutants blocked in one of the first three enzymes of the pyrimidine pathway produced no pyoverdine pigment while mutants blocked in the fourth, fifth or sixth steps produced copious quantities of pigment, just like wild type P. putida. The present study explored the correlation between pyrimidine auxotrophy and pigment production in P. aeruginosa. Since the pigment pyoverdine is a siderophore it may also be considered a virulence factor. Other virulence factors tested included casein protease, elastase, hemolysin, swimming, swarming and twitching motilities, and iron binding capacity. In all cases, these virulence factors were significantly decreased in the pyrB, pyrC or pyrD mutants and even in the presence of uracil did not attain wild type levels. In order to complete this comprehensive study, pyrimidine mutants blocked in the fifth (pyrE) and sixth (pyrF) steps of the biosynthetic pathway were examined in P. aeruginosa. A third mutant, crc, was also studied because of its location within 80 base pairs of the pyrE gene on the P. aeruginosa chromosome and because of its importance for carbon source utilization. Production of the virulence factors listed above showed a significant decrease in the three mutant strains used in this study when compared with the wild type. This finding may be exploited for novel chemotherapy strategies for ameliorating P. aeruginosa infections in cystic fibrosis patients.

Immediate and subsequent effects of response blocking on self-injurious behavior.

Description: Abstract In many institutional settings, blocking, response restriction (e.g., restraint, protective equipment), and re-direction procedures are used extensively as intervention for self-injurious behavior (SIB) and other forms of problem behavior. In the current study, a three component, multiple-schedule analysis was used to examine the immediate and subsequent effects of blocking on SIB that persisted in the absence of social reinforcement contingencies. During the first and third components the participant was in the room, alone, with no social consequences for SIB. During the second component (response restriction) the therapist sat in the room with the participant and blocked occurrences of SIB. Results indicated that, although blocking was effective in decreasing SIB while it was being implemented, subsequent effects were idiosyncratic across participants. Evidence of increased levels of SIB following blocking was observed for some participants.

Studies of spin alignment in ferrocenylsilane compounds and in regiospecific oxidation reactions of 1,9-dimethylpentacyclo [5.4.0.02,6.03,10.05,9]undecane-8,11-dione.

Description: Part I. The syntheses of a series of stable ferrocenylsilane compounds and their corresponding polyradical cations are reported. Electron spin properties of these molecules were investigated by cyclic voltammetry, ESR, and magnetic susceptibility measurements. All the compounds presented, showed significant electronic communication (>100 mV) between the redox centers by CV. Part II. Baeyer-Villiger oxidation of (1,9-dimethyl-PCU-8,11-dione) was performed using m-chloroperoxybenzoic acid in 1:2 molar ratios. The product obtained was the corresponding dilactone 113. The structure of the reaction products was established unequivocally via single crystal X-ray diffraction methods. The reaction of the 1,9-dimethyl-PCU-8,11-dione with 1:1 molar ratio of m-chloroperoxybenzoic acid produced again the dilactone 113, and not the expected monolactone 114. Ceric ammonium nitrate (CAN) promoted oxidation reaction of 1,9-dimethyl-PCU-8,11-dione afforded a mixture of dimethylated lactones, which indicated unique reaction mechanism pathways. These individual isomers, 115 and 116, have been isolated from these mixtures via column chromatography by using silica gel as adsorbent followed by fractional recrystallization of individual chromatography fractions. Structures of these pure products have been established unequivocally by application of single crystal X-ray crystallographic methods.

Room 2046: A Political Reading of Wong Kar-Wai's Chow-Mo Wan Trilogy through Narrative Elements and Mise-en-scene

Description: As ownership of Hong Kong changed hands from the United Kingdom to the People's Republic of China in 1997, citizens and filmmakers of the city became highly aware of the political environment. Film director Wong Kar-Wai creates visually stimulating films that express the anxieties and frustrations of the citizens of Hong Kong during this period. This study provides a political reading of Days of Being Wild (1991), In the Mood for Love (2000), and 2046 (2004) through analyzing various story elements and details within the mise-en-scene. Story elements include setting, dialogue, character relationships, character identities, thematic motifs, musical references, numerology, and genre manipulation. Wong also uses details within the films' mise-en-scene, such as props and color, to express political frustrations. To provide color interpretations, various traditional aesthetic guidelines, such as those prescribed by Taoism, Cantonese and Beijing opera, and feng shui, are used to read the films' negative comments on the handover process and the governments involved. When studied together the three films illustrate how Wong Kar-Wai creates narrative and visual references to the time and atmosphere in which he works, namely pre-and-post handover Hong Kong.

Social Self-Concept and Positive Illusory Bias in Boys and Girls With and Without Attention-Deficit/Hyperactivity Disorder

Description: This study examined differences in social self-concept, as measured by the Self-Perception Profile for Children (SPPC), between boys and girls with and without attention-deficit/hyperactivity disorder (ADHD) while controlling for internalizing symptoms. Ninety-six children between the ages of 8 and 13 participated in the study as part of a larger project. Teacher reports of social competence were collected using the Teacher Rating Scale (TRS). The results indicated ADHD children experienced more peer rejection than control children. ADHD girls appeared to be more susceptible to low social self-concept and competence than control children or ADHD boys. Inattentive symptoms were most predictive of teacher reports of competence. Positive illusory bias was not found to serve a protective function in children regardless of ADHD status. The implications of the current study and directions for future research are presented.

Democratic Pantheism in the Political Theory of Alexis de Tocqueville

Description: According to Alexis de Tocqueville, humanity is entering a new age of political and social equality, a new epoch in which the human race has no historical example or experience. As a result, he holds humanity's future will be largely determined by the political and moral choices made in this transitional time. For Tocqueville, the new egalitarian era is a forgone conclusion, but for him, the pressing question is whether humanity will choose a future in which it enchains itself to new forms of tyranny, or, whether the human race can establish the political and moral institutions designed to assure human freedom and dignity. In Tocqueville's view, liberty or slavery are the two choices modern men and women have in front of them, and it is the intent of this dissertation to explore Tocqueville's warning in regard to the latter choice. Tocqueville warns us that modern democratic peoples must beware of the moral and political effects of a new type of political philosophy, a political theory he terms democratic pantheism. Democratic pantheism is a philosophic doctrine that treats egalitarianism as a "religion" in which all social and political striving is directed toward realizing a providentially ordained strict equality of conditions. To attain this end, modern humanity gives up its right to self-government to an all-powerful "representative" state that will unconsciously (and as a result, unjustly) force equality on unequal human beings. Because this philosophy informs the core "soul" of a pantheistic social state, the vast majority of individuals are blissfully unaware that their humanity is diminished and their freedom is lost. The effect is a political and intellectual torpor wherein democratic citizens fall prey to a deterministic and insipid existence; and any thoughts of true independence and freedom of action are eventually extinguished--all due to the unknowing acceptance of a ...

Correspondence Between Verbal Behavior About Reinforcers and Performance Under Schedules of Reinforcement.

Description: Important advancements have been made in the identification of reinforcers over the past decade. The use of preference assessments has become a systematic way to identify preferred events that may function as reinforcers for an individual's behavior. Typically, preference assessments require participants to select stimuli through verbal surveys or engagement with stimuli as preferred or non-preferred. Not all studies go on to directly test the effects of the preferred stimuli, and even fewer studies directly test for the effects of the non- preferred stimuli. The present study systematically identified preferred and non-preferred stimuli in adult human subjects by verbal report and then proceeded to test the effects of both verbally reported preferred and non preferred events on single and concurrent schedules of reinforcement. The results are discussed in terms of contemporary concerns regarding preference and reinforcer assessments.

A morphological study of the avian (Gallus domesticus) ductus arteriosi during hatching.

Description: The ductus arteriosi (DA) are two blood vessels connecting the pulmonary arteries to the descending aorta in the avian embryo. Following hatching, the DA closes, separation of the systemic and pulmonary circulation. I present the morphological changes that occur in the chicken DA during prepipping, internal pipping, external pipping, and hatching. The avian DA consists of two distinct tissue types, a proximal and a distal portion. Histological examination shows developmental differences between the proximal and distal portions of the DA with regard to lumen occlusion, endothelial cells, smooth muscle and elastin. Endothelial cell proliferation begins to occur as early as external pipping, with the lumen almost completely occluded by the 3rd day of post-hatching life. Expression of vascular endothelial growth factor (VEGF) increases in avian endothelial cells during hatching. I provide a morphological timeline of changes in the DA as the chicken develops from embryo to hatchling.

Documentary Film: Access Denied

Description: Sculptor Eric McGehearty incorporates dyslexia, a learning disability, into his artwork to express his challenges with his limited ability to recognize and understand the written word. The film Access Denied focuses on Eric and his disability. Recognized in 1896, dyslexia has been studied and researched by scientists and educators. New assistive technology is now available to aid dyslexics in reading and writing. Specialized schools provide techniques to improve student learning. However, some options are not readily available to the general public; therefore, information about how to deal with the disability is not easily accessed. The aims of this documentary are to raise awareness of available resources to assist with learning as well as to demonstrate a relationship between art and dyslexia.

The Effects of Using Children's Literature with Adolescents in the English As a Foreign Language Classroom.

Description: This study provides quantitative and qualitative data about the effects of using children's literature with adolescents in a language classroom and the role of children's literature in students' second/foreign language development, including listening, speaking, reading, and writing skills. The study presents qualitative data about the role of children's literature in developing more positive attitudes toward reading in the second/foreign language and toward reading in general. With literature being a model of a culture, presenting linguistic benefits for language learners, teaching communication, and being a motivator in language learning, this study presents empirical data that show that inclusion of children's literature in adolescents' second/foreign language classroom promotes appreciation and enjoyment of literature, enhances the development of language skills, stimulates more advanced learning, and promotes students' personal growth.

Family Influences on Young Adult Career Development and Aspirations

Description: The purpose of this study was to examine family influences on career development and aspirations of young adults. Theories and research have examined the influence parents have on children's career development, but because of the multiple factors that influence career choices, understanding the family's influence is complex. The current study utilized ideas from self-determination, attachment, and career development theories to develop a framework for understanding how families influence young adult career development and aspirations. Rather than directly influencing career decisions, the family was proposed to influence processes within individuals that directly influence successful career development. This study used hierarchical regression analyses to test whether different aspects of family relationships and the family environment affect processes within young people, which in turn influence career development. A sample of 99 female and 34 male undergraduate students between 18 and 20 (mean age 18.67) completed questionnaires. Results support the idea that different aspects of the family influence diverse factors of career development and future aspirations. The achievement orientation of the family was predictive of career salience and extrinsic aspirations. Conflict with mothers was predictive of career salience, yet support and depth in the relationship with mothers and low amounts of conflict in the relationship with fathers were predictive of career maturity. High career salience was also predictive of career maturity. The hypothesis that factors play a mediating role between the family and career development variables was not supported. These findings suggest future research should assess multiple aspects of the family and multiple facets regarding career development to more fully understand this process. In addition, findings support the idea that career counselors should assess family functioning when helping young people in their career development journey.
