This study examined the relationship between time of exposure to the human face and accurate subsequent photo line-up identification. A volunteer group of 124 undergraduate students was divided into three approximately equal sized subgroups. The three groups were then exposed to a video or a portion of a video depicting a theft. Exposure times ranged from two minutes to 30 seconds. The subjects were then given a questionnaire and shown a photo line-up of the mock perpetrator and five foils. Subjects were asked to identify the perpetrator and mark that identification on the questionnaire. Results of the experiment indicated that the longer a subject was exposed the greater the possibility of an accurate identification.

Recent research found insomnia is a risk factor for psychiatric disorders in adults. To see if the same would be true in adolescents, the current study re-analyzed data from a national longitudinal study collected by ADDHealth that evaluated health behaviors in 4552 adolescents (mean age 14.9 years [SD 1.7]) at baseline and again 7-8 years later (n = 3489) during young adulthood. Insomnia was reported by 9.2% of the adolescents. Cross-sectionally, adolescent insomnia was associated with alcohol, cannabis, non-cannabis drugs, and tobacco use, and depression after controlling for gender and ethnicity. Prospectively, adolescent insomnia was a significant risk factor for depression diagnosis, suicidal ideation, and the use of depression and stress prescription medications in young adulthood after controlling for gender, ethnicity, and significant baseline variable. In addition, a trend was noted for suicidal attempts.

The thesis has two parts. Part I is a critical essay entitled "Lessons Under the Amfalula." Part II is the collection of poems entitled "Animals That Die."

Due to the long duration required to perform manual knowledge entry by human knowledge engineers it is desirable to find methods to automatically acquire knowledge about the world by accessing online information. In this work I examine using the Cyc ontology to guide the creation of Naïve Bayes classifiers to provide knowledge about items described in Wikipedia articles. Given an initial set of Wikipedia articles the system uses the ontology to create positive and negative training sets for the classifiers in each category. The order in which classifiers are generated and used to test articles is also guided by the ontology. The research conducted shows that a system can be created that utilizes statistical text classification methods to extract information from an ad-hoc generated information source like Wikipedia for use in a formal semantic ontology like Cyc. Benefits and limitations of the system are discussed along with future work.

Substance abuse and dependence causes many problems in our society. Attachment style may be useful in the etiology of this problem. Using archival data, this study hypothesizes men in a court-ordered facility will be more likely to have an insecure attachment style. The participants were 73 males ages 18-49. The Adult Attachment Scale (AAS) was used to measure adult romantic attachment style. Through cluster analysis and conversion of the subscales of the AAS, four attachment styles were measured. Men were more likely to have an insecure attachment style especially a Fearful style. The study concludes with limitations of the results and a discussion about possible interventions based on attachment style.

Heinrich Koch completed his treatise in 1793, a pioneering work regarding the musical phrase as well as a sonata form description (lacking that term). Composition of Opus 18 began in 1798, a momentous project for several reasons in Beethoven's early career. Here, the theories expressed in Koch's Versuch are taken as an analytic springboard into a thorough analysis of the first movement of the quartet published no. 3, which was the first composed; additionally, nos. 1 and 6 are explored to a lesser degree. This study in phrase-analysis demonstrates significance in the fundamental ideas of Koch as applied to a masterwork of the turn of the 19th century.

This paper presents the lives and early feminist works of two modernist era poets, Laura Riding Jackson and Muriel Rukeyser. Despite differences of style, the two poets shared a common theme of essentialist feminism before its popularization by 1950s and 60s second wave feminists. The two poets also endured periods of poetic silence or self censorship which can be attributed to modernism, McCarthyism, and rising conservatism. Analysis of their poems helps to remedy their exclusion from the common canon.

Modern high performance computing is dependent on parallel processing systems. Most current benchmarks reveal only the high level computational throughput metrics, which may be sufficient for single processor systems, but can lead to a misrepresentation of true system capability for parallel systems. A new benchmark is therefore proposed. CLUE (Cluster Evaluator) uses a cellular automata algorithm to evaluate the scalability of parallel processing machines. The benchmark also uses algorithmic variations to evaluate individual system components' impact on the overall serial fraction and efficiency. CLUE is not a replacement for other performance-centric benchmarks, but rather shows the scalability of a system and provides metrics to reveal where one can improve overall performance. CLUE is a new benchmark which demonstrates a better comparison among different parallel systems than existing benchmarks and can diagnose where a particular parallel system can be optimized.

Proteomic techniques were used to evaluate the protein profile of the earthworm, (Lumbricus terrestris), following a bacterial challenge. One control group received no injection; a second control group received injections of phosphate buffer solution (PBS). The experimental group received injections of PBS containing (Aeromonas hydrophila). After incubation for 12 hours at 20°C, coelomic fluid was collected from each group for analysis by 2-D electrophoresis. There were significant differences in spot appearance and density between control and experimental groups. Sixteen spots showed a two-fold increase in density and 63 showed at least a two-fold decrease in density between samples from control and bacteria-challenged earthworms, respectively, suggesting up- and down-modulation of proteins potentially involved in the earthworm's response to bacterial challenge.

The purpose of this study was to examine cognitive complexity, extremity, and the relationship between social repertory grids and life events repertory grids (LERG) in people who report a history of trauma. Effects of type of trauma on complexity and extremity scores of each type of grid were examined. Prior research into repertory grids and trauma has used only one type of grid, predominantly social grids or LERGs. Therefore, a natural, progressive step in the grid research involved investigating how individuals integrate social and life event constructs. It was hypothesized, and results show, that there is a positive correlation between complexity scores and extremity scores of social grids and LERGs. However it was not found that there was a negative correlation between trauma history and complexity scores, and that trauma acts as a moderator for cognitive complexity. Instead, it appears that the social facet of experience is key to understanding perception of traumatic experiences. Additionally, number of traumas experienced might affect social construct elaboration.

In this thesis I look at the theory of compact operators in a general Hilbert space, as well as the inverse of the Hamiltonian operator in the specific case of L2[a,b]. I show that this inverse is a compact, positive, and bounded linear operator. Also the eigenfunctions of this operator form a basis for the space of continuous functions as a subspace of L2[a,b]. A numerical method is proposed to solve for these eigenfunctions when the Hamiltonian is considered as an operator on Rn. The paper finishes with a discussion of examples of Schrödinger equations and the solutions.

In this thesis two collaborative localization techniques are studied: multidimensional scaling (MDS) and maximum likelihood estimator (MLE). A synthesis of a new location estimation method through a serial integration of these two techniques, such that an estimate is first obtained using MDS and then MLE is employed to fine-tune the MDS solution, was the subject of this research using various simulation and experimental studies. In the simulations, important issues including the effects of sensor node density, reference node density and different deployment strategies of reference nodes were addressed. In the experimental study, the path loss model of indoor environments is developed by determining the environment-specific parameters from the experimental measurement data. Then, the empirical path loss model is employed in the analysis and simulation study of the performance of collaborative localization techniques.

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.

The incidence of sexual assault inundates the courts with many cases each year. Given the unique nature of the crime, judges and juries are faced with an array of different scenarios to which they are required to make fair, justifiable and consistent decisions. I examine child sexual assault cases of Dallas County 1999-2005, I look at both legal and extralegal factors including case characteristics, institutional characteristics and characteristics of the defendants and the victims. First, I examine the impact of the independent variables on sentence length using regression analysis to determine influences on sentencing for judges and juries. Second, I examine the same factors using Probit analysis to determine which characteristics make a life sentence more probable for those decision-makers.

A novel scheme of optimizing the individual components of a phase locked loop (PLL) which is used for stable clock generation and synchronization of signals is considered in this work. Verilog-A is used for the high level system design of the main components of the PLL, followed by the individual component wise optimization. The design of experiments (DOE) approach to optimize the analog, 45nm voltage controlled oscillator (VCO) is presented. Also a mixed signal analysis using the analog and digital Verilog behavior of components is studied. Overall a high level system design of a PLL, a systematic optimization of each of its components, and an analog and mixed signal behavioral design approach have been implemented using cadence custom IC design tools.

The purpose of this thesis is to examine the impact of International Monetary Fund (IMF) loans since the adoption of the governance mandate on overall government capability. The study will explore whether the presence of IMF loans in developing countries enhances state capacity. Administrative capacity is of particular importance because it is a requisite for the integration of state and society in the national political arena and encourages joint involvement of government and citizenry in overall representation of societal interests. The model designed to test the two primary hypotheses is comprised of a simultaneous system of equations. Despite criticisms of IMF conditionality arrangements, it appears that these programs are largely effective at increasing administrative capacity, an important factor in achieving economic growth and national ownership of IMF development programs.

The tetraruthenium cluster H4Ru4(CO)12 has been studied for its reactivity with the unsaturated diphosphine ligands (Z)-Ph2PCH=CHPPh2, 4,5-bis (diphenylphosphino)-4-cyclopenten-1,3-dione, bis(diphenyphosphino)benzene and 1,8- bis(diphenyl phosphino)naphthalene under thermal, near-UV photolysis, and Me3NO-assisted activation. All three cluster activation methods promote loss of CO and furnish the anticipated substitution products that possess a chelating diphosphine ligand. Clusters 1, 2, 3 and 4 have been characterized in solution by IR and NMR spectroscopies, and these data are discussed with respect to the crystallographically determined structures for all new cluster compounds. The 31P NMR spectral data and the solid-state structures confirm the presence of a chelating diphosphine ligand in all four new clusters. Sealed NMR tubes containing clusters 1, 2, 3 and 4 were found to be exceeding stable towards near-UV light and temperatures up to ca. 100°C. The surprisingly robust behavior of the new clusters is contrasted with the related cluster Ru3(CO)10(bpcd) that undergoes fragmentation to the donor-acceptor compound Ru2(CO)6(bpcd) and the phosphido-bridged compound Ru2(CO)6 (µ-PPh2)[µ-C=C(PPh2)C(O)CH2C(O)] under mild conditions. The electrochemical properties have been investigated in the case of clusters 1 and 2 by cyclic voltammetry, and the findings are discussed with respect to the reported electrochemical data on the parent cluster H4Ru4(CO)12.

This study investigated a proposed model hypothesizing that parental divorce would directly effect romantic beliefs and attitudes, romantic attachment and relationship characteristics. A sample of 494 young adults between the ages of 18 and 35 indicated that parental divorce does have a negative impact on romantic beliefs, attitudes toward marriage and divorce, romantic attachments, and relationship characteristics when considered in the context of marriage. Those individuals whose parents divorced reported less positive attitudes toward marriage and more openness toward divorce. Those whose parents divorced reported less idealized romantic beliefs and less of a belief that love will find a way. Those who experienced parental divorce had a more fearful romantic attachment style and reported a lower chance of marriage to their current partner.

This study uses survey data collected from a convenience sample of undergraduate students (N=89). A vignette survey design is employed to measure social rejection of striptease performers compared to a control group. Data is also collected on negative stereotypes held about striptease performers, which are correlated with social rejection. Link and Phelan's conceptualization of the stigma process provides the theoretical framework for this analysis. Findings suggest that striptease performers experience higher levels of social rejection and are perceived more negatively than the control group and that endorsement of negative stereotypes is associated with social rejection.

Four elementary school children were tested on 120 words containing the short e (e.g., ten, pen) and short a (e.g., tan, pan) sounds. Words were tested in the hear-write (H/W) and see-say (S/S) channels. No programmed consequences were scheduled during baseline (BL) tests 1-3. After BL, an error analysis categorized words based on channel error and topography of error. Praise was delivered during tests 4-6 for correct responses. Children's responses were variable within channel and across channels for a majority of words. By the end of the praise phase, there was a decrease in the number of words with errors, for all children in their error word group. Error topographies began to stabilize for some words during praise.

This study analyzed the effects of a training package containing response constraint, self-evaluation, reinforcement, and a fading procedure on written letter components and whole letter writing in four elementary school participants. The effect on accuracy of written components was evaluated using a multiple-baseline-across components and a continuous probe design of components, as well as pre-test, baseline, and post-test measures. The results of this study show that response constraint and self-evaluation quickly improved students' performance in writing components. Fading of the intervention was achieved quickly and performance maintained. Results also show that improvement in component writing improved whole letter and full name writing and letter reversals in the presence of a model were corrected.

I present a time synchronization algorithm for wireless sensor networks that aims to conserve sensor battery power. The proposed method creates a hierarchical tree by flooding the sensor network from a designated source point. It then uses a hybrid algorithm derived from the timing-sync protocol for sensor networks (TSPN) and the reference broadcast synchronization method (RBS) to periodically synchronize sensor clocks by minimizing energy consumption. In multi-hop ad-hoc networks, a depleted sensor will drop information from all other sensors that route data through it, decreasing the physical area being monitored by the network. The proposed method uses several techniques and thresholds to maintain network connectivity. A new root sensor is chosen when the current one's battery power decreases to a designated value. I implement this new synchronization technique using Matlab and show that it can provide significant power savings over both TPSN and RBS.

A rectifier is an electrical device, comprising one or more semiconductor devices arranged for converting alternating current to direct current by blocking the negative or positive portion of the waveform. The purpose of this study would be to evaluate dynamic and static electrical characteristics of rectifier chips fabricated with (a) DY8 process and (b) YI8 process and compare them with the existing DI8 process rectifiers. These new rectifiers were tested to compare their performance to meet or exceed requirements of lower forward voltages, leakage currents, reverse recovery time, and greater sustainability at higher temperatures compared to diodes manufactured using boron as base (DI8 process diodes) for similar input variables.

I examine a key shift in Michel Foucault's political philosophy from a position in which he was a staunch anti-humanist, to a final position in which he advocated not only the ability of the subject to influence his political condition, but also the individual freedoms assured by a democratic form of government. I begin by summarizing his overall critique of the post-Enlightenment West, and then explain how his observation of the Iranian Revolution served as a key turning point concerning his attitude towards the subject. Next, I elaborate on the direction of Foucault's late writings and examine how his new conceptualization of the subject leads him to embrace a democratic political system albeit free from Enlightenment philosophical foundations. I conclude by critiquing Foucault's foundationless democratic theory on the basis that it would ultimately undermine the individual freedoms and aesthetic development that he seeks to protect.
