The Role of Eigenvalues of Parity Check Matrix in Low-Density Parity Check Codes

Description: The new developments in coding theory research have revolutionized the application of coding to practical systems. Low-Density Parity Check (LDPC) codes form a class of Shannon limit approaching codes opted for digital communication systems that require high reliability. This thesis investigates the underlying relationship between the spectral properties of the parity check matrix and LDPC decoding convergence. The bit error rate of an LDPC code is plotted for the parity check matrix that has d… more

The Role of Expectations on Attention Performance

Description: AD/HD medications are shown to be significantly more successful at enhancing attention/concentration performance in individuals with AD/HD than placebo treatments. Few studies, however, have investigated the possibility of a placebo reaction in both medication and placebo groups by comparing placebo treatments to no treatment at all. Using an undergraduate population, I evaluated the effect of expectations about a treatment's efficacy on performance in an attention/concentration task. In additi… more

The Role of Experiential Avoidance in Trauma, Substance Abuse, and Other Experiences

Description: Experiential avoidance (EA) is a process in which a person attempts to avoid, dismiss, or change experiences such as emotions, behaviors, and thoughts. EA is associated with a number of psychological disorders and is generally harmful to psychological well-being. Various studies have explored the role of EA as a mediator, while others have studied EA as a moderator. The current study aimed to further understand and broaden the knowledge of the role of EA in regard to trauma, substance abuse, … more

The Role of Faith-Based Congregations during Disaster Response and Recovery: A Case Study of Katy, Texas

Description: When governments are unable or unwilling to provide necessary relief to communities, local faith-based congregations (FBCs) step in and fill the gap. Though shown to provide for so many needs following disaster, FBCs have largely been left out of the institutional emergency management cycle. The aim of this study was to explore the role of FBCs in the disaster response and recovery process and investigate how recovery impacts FBCs. The primary objective of this study is to gain a better underst… more

The Role of Family in Alcohol Consumption Among Turkish Adolescents

Description: Alcohol consumption among adolescents is an important issue because of its link to many negative social and health problems, including depression, suicide, and aggression. Drawing from Hirschi’s social bonding theory and Agnew’s general strain theory, this study examines the effects of family relations on alcohol consumption among Turkish adolescents. Social bonding theory suggests that individuals with stronger social bonds are less likely to use alcohol than individuals with weaker social bon… more

The role of federal district courts on desegregation: A logistic regression analysis of the factors that influence prodesegregation outcomes.

Description: In this study I analyzed the 1089 desegregation outcomes in federal district courts that occurred between 1994 and 2004 in order to identify a) the legal and non-legal factors in the litigation process that predict pro-desegregation outcomes and b) the judicial patterns that impact the future of desegregation policy. Twenty-one legal and non-legal variables were analyzed via logistic regression analysis to identify factors that predict pro-desegregation outcomes. Only three predictor variable… more

The Role of Female Stereotyping in Seven Elizabethan Tragedies

Description: During the Elizabethan period, certain stereotypes existed concerning women. Seven tragedies were examined to discover the role played by those stereotypes in the dramas. These include "The Spanish Tragedy," "Edward II," "Bussy D'Ambois," "The Changeling," "A Woman Killed with Kindness," "Othello," and "The Duchess of Malfi." Female stereotyping was found to be used in three important ways: in characterization, in motivation, and as a substitute for motivation. Some of the plays rely on stereot… more

The Role of Fluency in the Emergence of the Derived Relations of Stimulus Equivalence

Description: Fluent component performances may be more readily available for recombination into more complex repertoires. This experiment considered the stimulus equivalence preparation as a laboratory analog for the co-adduction said to occur in generative instruction. Seven adults received minimum training on 18 conditional discriminations, components of 9 potential stimulus equivalence classes. Training was interrupted periodically with tests to determine whether fluency of original relations predicted e… more

The Role of Gabergic Inhibition in Modulating Receptive Field Size of Cuneate Neurons

Description: A blockade of GABAergic inhibition increases the receptive field(RF) size of most somatosensory cortex (SI) and some ventrobasal thalamus (VB) neurons. The results suggest RF size of cuneate neurons may be modulated through GABAa and GABAb receptors, independent of firing frequency.

Role of GPR17 in Thrombocyte Aggregation in Adult Zebrafish

Description: GPR17, a uracil nucleotide cysteinyl leukotriene receptor, belongs to the GPCR (G protein coupled receptor) family. It has been shown recently that inhibiting this protein in the nervous system in mice can lead to blockage of oligodendrocyte maturation, which supports myelin repair. Interestingly, our laboratory found GPR17 in thrombocytes. However, we do not know whether it has any function in thrombocyte aggregation or the nature of the ligand. In this paper, we studied the role of GPR17 in h… more

The Role of Height and Weight in the Performance of Salesmen of Ordinary Life Insurance

Description: Despite the obvious importance attached to the psychological significance of height and weight in everyday life, few researchers have studied the relationship of these variables to the sales performance of ordinary life insurance salesmen. In the present study, it was hypothesized that (1) taller and/or heavier ordinary life insurance salesmen are more successful than shorter and/or lighter ordinary life insurance salesmen; (2) those who possess more "ideal statures" are more successful than th… more

The Role of Implied Texture in Figural Imagery

Description: This study explored how implied texture was used to give meaning to figural imagery. Several questions were answered in proceeding with the creative project: 1. Did implied texture abstract the figurative image? If so, how was content affected? 2. Did implied texture act as an obstruction to content? 3. Did implied texture act as an integral part of content? 4. Did implied texture exist as a separate entity from content?

The Role of Individuation Processes in the Launching of Children into Adulthood

Description: The purpose of this study was to examine the extent to which levels of individuation and separation in adulthood would predict adjustment to the empty nest transition. Two-hundred and twenty-seven adults (M age = 48) who had experienced the empty nest within the last year completed a battery of scales assessing individuation from family of origin, spouse, and children as well as measures of adjustment, role strain, coping, and sex role attitudes. MANOVAS and hierarchical regression analyses sug… more

The Role of Intelligent Mobile Agents in Network Management and Routing

Description: In this research, the application of intelligent mobile agents to the management of distributed network environments is investigated. Intelligent mobile agents are programs which can move about network systems in a deterministic manner in carrying their execution state. These agents can be considered an application of distributed artificial intelligence where the (usually small) agent code is moved to the data and executed locally. The mobile agent paradigm offers potential advantages over many… more
