Application Of The Empirical Likelihood Method In Proportional Hazards Model, Bin He Jan 2006

Application Of The Empirical Likelihood Method In Proportional Hazards Model, Bin He

Electronic Theses and Dissertations

In survival analysis, proportional hazards model is the most commonly used and the Cox model is the most popular. These models are developed to facilitate statistical analysis frequently encountered in medical research or reliability studies. In analyzing real data sets, checking the validity of the model assumptions is a key component. However, the presence of complicated types of censoring such as double censoring and partly interval-censoring in survival data makes model assessment difficult, and the existing tests for goodness-of-fit do not have direct extension to these complicated types of censored data. In this work, we use empirical likelihood (Owen, 1988) …

Factors Influencing User-Level Success In Police Informationsharing: An Examination Of Florida's Finder System, Jr Ernest Scott

Electronic Theses and Dissertations

An important post-9/11 objective has been to connect law enforcement agencies so they can share information that is routinely collected by police. This low-level information, gathered from sources such as traffic tickets, calls for service, incident reports and field contacts, is not widely shared but might account for as much as 97% of the data held in police records systems. U.S. policy and law assume that access to this information advances crime control and counterterrorism efforts. The scarcity of functioning systems has limited research opportunities to test this assumption or offer guidance to police leaders considering investments in information sharing. …

Immediate Versus Delayed Feedback In Simulation Based Training: Matching Feedback Delivery Timing To The Cognitive Demands Of Th, Amy Bolton Jan 2006

Immediate Versus Delayed Feedback In Simulation Based Training: Matching Feedback Delivery Timing To The Cognitive Demands Of Th, Amy Bolton

Electronic Theses and Dissertations

Optimal delivery of instruction is both critical and challenging in dynamic, scenario-based training (SBT) computer simulations such as those used by the military. Tasks that human instructors must perform during these sorts of simulated training exercises can impose a heavy burden on them. Partially due to advances in the state-of-the-art in training technology and partially due to the military's desire to reduce the number of personnel required, it may be possible to support functions that overburdened instructors perform by automating much of the SBT process in a computer simulation. Unfortunately though, after more than 50 years of literature documenting research …

Integrated Inp Photonic Switches, Daniel May-Arrioja Jan 2006

Integrated Inp Photonic Switches, Daniel May-Arrioja

Electronic Theses and Dissertations

Photonic switches are becoming key components in advanced optical networks because of the large variety of applications that they can perform. One of the key advantages of photonic switches is that they redirect or convert light without having to make any optical to electronic conversions and vice versa, thus allowing networking functions to be lowered into the optical layer. InP-based switches are particularly attractive because of their small size, low electrical power consumption, and compatibility with integration of laser sources, photo-detectors, and electronic components. In this dissertation the development of integrated InP photonic switches using an area-selective zinc diffusion process …

An Investigation Of Altruism And Personality Variables Amongbeginning Counseling Students, Laura Schmuldt Jan 2006

An Investigation Of Altruism And Personality Variables Amongbeginning Counseling Students, Laura Schmuldt

Electronic Theses and Dissertations

Altruism is loosely defined as a desire to help others as well as acts and behaviors towards that end, particularly when no expectation of personal gain or reward exists (Batson, Fultz, Schoenrade & Paduano, 1987). It seems likely that individuals who choose to pursue acareer in counseling might be doing so out of some altruistic interest; in other words a desire to come to the aid of others in distress. It has been noted as well that some individuals may enter the counseling profession based more on self-interest; for example, as "wounded healers" hoping to work on personal issues (Wheeler, …

A Comparison Of Ordinary Least Squares, Weighted Least Squares, And Other Procedures When Testing For The Equality Of Regression, Patrick J. Rosopa Jan 2006

A Comparison Of Ordinary Least Squares, Weighted Least Squares, And Other Procedures When Testing For The Equality Of Regression, Patrick J. Rosopa

Electronic Theses and Dissertations

When testing for the equality of regression slopes based on ordinary least squares (OLS) estimation, extant research has shown that the standard F performs poorly when the critical assumption of homoscedasticity is violated, resulting in increased Type I error rates and reduced statistical power (Box, 1954; DeShon & Alexander, 1996; Wilcox, 1997). Overton (2001) recommended weighted least squares estimation, demonstrating that it outperformed OLS and performed comparably to various statistical approximations. However, Overton's method was limited to two groups. In this study, a generalization of Overton's method is described. Then, using a Monte Carlo simulation, its performance was compared to …

External Cavity Multiwavelength Semiconductor Mode-Locked Laser Gain Dynamics, Luis Archundia-Berra Jan 2006

External Cavity Multiwavelength Semiconductor Mode-Locked Laser Gain Dynamics, Luis Archundia-Berra

Electronic Theses and Dissertations

External cavity semiconductor mode-locked lasers can produce pulses of a few picoseconds. The pulses from these lasers are inherently chirped with a predominant linear chirp component that can be compensated resulting in sub-picosecond pulses. External cavity semiconductor mode-locked lasers can be configured as multiwavelength pulse sources and are good candidates for time and wavelength division multiplexing applications. The gain medium in external cavity semiconductor mode-locked lasers is a semiconductor optical amplifier (SOA), and passive and hybrid mode-locked operation are achieved by the introduction of a saturable absorber (SA) in the laser cavity. Pump-probe techniques were used to measure the intracavity …

Three-Photon Absorption Process In Organic Dyes Enhanced By Surface Plasmon Resonance, Ion Cohanoschi Jan 2006

Three-Photon Absorption Process In Organic Dyes Enhanced By Surface Plasmon Resonance, Ion Cohanoschi

Electronic Theses and Dissertations

Multi-photon absorption processes have received significant attention from the scientific community during the last decade, mainly because of their potential applications in optical limiting, data storage and biomedical fields. Perhaps, one of the most investigated processes studied so far has been two-photon absorption (2PA). These investigations have resulted in successful applications in all the fields mentioned above. However, 2PA present some limitations in the biomedical field when pumping at typical 2PA wavelengths. In order to overcome these limitations, three-photon absorption (3PA) process has been proposed. However, 3PA in organic molecules has a disadvantage, typical values of σ3' are small (10-81 …
