Global Assessment Of Severity Of Epilepsy (Gase) Scale In Children With Epilepsy: Construct Validity, Stability, And Responsiveness, Cindy J. Chan

Electronic Thesis and Dissertation Repository

The Global Assessment of Severity of Epilepsy (GASE) Scale is a single-item, 7-point global rating scale designed for neurologist-report of overall severity of epilepsy in children. Preliminary evidence suggested it may be valid and reliable for research and clinical use. Data from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES) was analyzed to evaluate validity, stability, and responsiveness of GASE scores. Spearman’s Rho indicated that GASE was moderately correlated with key aspects of epilepsy but weakly correlated with parents’ perceptions of child health. Frequency and intensity of seizures and interference of epilepsy or drugs with daily activities …

Can Wearable Sensors Help Assess The Reliability Of Self-Reports In Mobile Health Studies?, Hillol Sarker

Electronic Theses and Dissertations

Self-report in the form of Ecological Momentary Assessment (EMA) has been the primary instrument to collect measurements from participants in their natural environment. Given numerous sources of biases and inaccuracies in self-report, assessing and improving the reliability of self-report has been the subject of continuing research. However, to date, there exist only limited lab based methods to check the veracity of collected self-report data. Increasing adoption of sensors in field studies that sometimes can passively measure the same phenomena that have been traditionally included in EMA self-report has opened up a new opportunity to assess the reliability of self-reports.In this …

Robust Geotechnical Design - Methodology And Applications, Lei Wang

All Dissertations

This dissertation is aimed at developing a novel robust geotechnical design methodology and demonstrating this methodology for the design of geotechnical systems. The goal of a robust design is to make the response of a system insensitive to, or robust against, the variation of uncertain geotechnical parameters (termed noise factors in the context of robust design) by carefully adjusting design parameters (those that can be controlled by the designer such as geometry of the design). Through an extensive investigation, a robust geotechnical design methodology that considers explicitly safety, robustness, and cost is developed. Various robustness measures are considered in this …

Evaluation And Application Of Instruments Measuring Spatial Ability And Attitude For College Chemistry Students, Xiaoying Xu

USF Tampa Graduate Theses and Dissertations

Student performance in college chemistry courses remains a concern for educators seeking to help improve the future STEM workforce. Besides math ability and prior chemistry knowledge, spatial ability and attitude toward chemistry have been considered as important factors influencing college chemistry performance. This work includes five studies and uses data collected from instruments to examine the relationships of these two factors - spatial ability and attitude - with student chemistry performance, and provides psychometric evidence for using the Purdue Visualization of Rotations test (ROT) and Attitude toward the Subject of Chemistry Inventory (ASCIv2) to measure these two factors, respectively, in …

The Frame Of Reference And Other Problems, Richard D. Friedman, Jeffrey L. Fisher

Michigan Law Review First Impressions

George argues that, centuries ago, jurists did not distinguish between testimonial and nontestimonial hearsay, and so the distinction cannot be a historically well-grounded basis for modern confrontation doctrine. The argument proceeds from an inaccurate frame of reference. When the confrontation right developed, principally in the sixteenth and seventeenth centuries, and English defendants—Raleigh among them—demanded that adverse witnesses be brought face to face with them, they were making a procedural assertion as to how witnesses must give their testimony. (Giving testimony is what witnesses in litigation do.) Rarely did they phrase this claim in terms of hearsay, for the simple reason …

Estimation Of Multi Component Systems Reliability In Stress-Strength Models, Adil H. Khan, T R. Jan

Journal of Modern Applied Statistical Methods

In a system with standby redundancy, there are a number of components only one of which works at a time and the other remain as standbys. When an impact of stress exceeds the strength of the active component, for the first time, it fails and another from standbys, if there is any, is activated and faces the impact of stresses, not necessarily identical as faced by the preceding component and the system fails when all the components have failed. Sriwastav and Kakaty (1981) assumed that the components stress-strengths are similarly distributed. However, in general the stress distributions will …

Discrete Generalized Burr-Type Xii Distribution, B. A. Para, T. R. Jan

Journal of Modern Applied Statistical Methods

A discrete analogue of generalized Burr-type XII distribution is introduced using a general approach of discretizing a continuous distribution. It may be worth exploring the possibility of developing a discrete version of the six parameter generalized Burr-type XII distribution for use in modeling a discrete data. This distribution is suggested as a suitable reliability model to fit a range of discrete lifetime data, as it is shown that hazard rate function can attain monotonic increasing (deceasing) shape for certain values of parameters. The equivalence of discrete generalized Burr-type XII (DGBD-XII) and continuous generalized Burr-type XII (GBD-XII) distributions has been established. …

Family Accommodation In Adults With Obsessive-Compulsive Disorder: Psychometric Properties Of The Family Accommodation Scale - Patient Version, Monica S. Wu

USF Tampa Graduate Theses and Dissertations

Family accommodation is a salient construct within the context of obsessive-compulsive disorder (OCD) and occurs in a large majority of affected individuals and their families. Accommodating behaviors can manifest in various ways, including participation in the patient's rituals, modifying everyday routines, facilitating compulsive behaviors, or providing reassurance. It has been repeatedly linked to negative outcomes, such as attenuated treatment response, increased obsessive-compulsive symptom severity, higher levels of family distress, and lower levels of functioning. As such, it is of significant clinical importance to have a standardized measure that is able to be used in research and clinical practice.

The Family …

Psychometric Evaluation Of Self-Report Pain And Disability Measures For Elbow Disorders, Joshua Vincent

Electronic Thesis and Dissertation Repository

Elbow disorders are one of the commonest musculoskeletal problems with a prevalence of 9% in men and 8.1% in women. Patient centered care is the goal of current healthcare delivery models; but optimizing treatment outcome and clinical research is hampered by a lack of outcome measures. Since pain and disability resulting from elbow disorders are experienced differently across individuals, they are best captured by patient reported outcome measures (PROM).

PROMs like the Patient-rated Elbow Evaluation (PREE); American Shoulder and Elbow surgeons – Elbow form (pASES-e) have been developed for use in elbow disorders, but important questions remain about their measurement …

Screening And Diagnostic Validity Of Affinity 2.5, Heather Lynn Stephenson

Theses and Dissertations

Affinity 2.5 is a computer-based instrument designed to assess sexual interest using viewing-time measures. Viewing-time measures of sexual interest have been developed to identify individuals with deviant sexual interest. The purpose of this study is to examine the validity of Affinity 2.5 in screening and diagnosing individuals with sexually deviant interests. This study used viewing time profiles of known sexual offenders compared to norm-referenced profiles of an exclusively heterosexual, non-pedophilic college population. Participants were 155 males and 3 females who had sexually offended against children and 63 male and 84 female non-offender college students. Results show that 43.7% of offenders …

Sustainability of urban WDS is evaluated in terms of hydraulic efficiency and water quality. The first step is to assess sustainability of an example urban WDS by using sustainability index (SI). The SI is measured by reliability, resiliency, and vulnerability performance indices. Pressure and water age are selected as main parameters to determine sustainability. Once the SIs for pressure and water age are calculated by …

Prognostic-Based Life Extension Methodology With Application To Power Generation Systems, Seyed Ahmad Niknam

Doctoral Dissertations

Practicable life extension of engineering systems would be a remarkable application of prognostics. This research proposes a framework for prognostic-base life extension. This research investigates the use of prognostic data to mobilize the potential residual life. The obstacles in performing life extension include: lack of knowledge, lack of tools, lack of data, and lack of time.

This research primarily considers using the acoustic emission (AE) technology for quick-response diagnostic. To be specific, an important feature of AE data was statistically modeled to provide quick, robust and intuitive diagnostic capability. The proposed model was successful to detect the out of control …

Projections Of Future Us Design Wind Speeds Due To Climate Change For Estimating Hurricane Losses, Fangqian Liu

All Dissertations

Hurricane is among the most dangerous and costliest natural hazards that affect the coastal environment of the United States (U.S.) every year. Hurricane activities have been observed to change in many aspects since the last century including the changes in both intensity and annual storm frequency. The extent to which aspect of climate change contributes to the variation in hurricane activities from long-term historical statistics is still not clearly understood at this point. This study examines the impacts of two climate change effects (change in annual storm frequency and sea surface temperature) on future U.S. design wind speeds for the …

Reliability Generalization Of The Multigroup Ethnic Identity Measure-Revised (Meim-R), Hayley Marie Herrington

Theses and Dissertations

The strength of ethnic identity has been linked to higher academic achievement, academic attainment, and overall psychological wellbeing. The Muligroup Ethnic Identity Measure (MEIM) was developed to measure ethnic identity development, and this measure has been used widely. The MEIM has since been updated to the Multigroup Ethnic Identity Measure–Revised (MEIM–R). The relatively new MEIM–R has not been widely studied. In order to solidify researchers' confidence in the measure, a reliability generalization analysis was performed and the data compared to the original MEIM. Random-effects weighted models evaluated internal consistency coefficients (Chronbach's alpha). The MEIM–R demonstrated adequate reliability coefficients (average α …

Ultimate Codes: Near-Optimal Mds Array Codes For Raid-6, Zhijie Huang, Hong Jiang, Chong Wang, Ke Zhou, Yuhong Zhao

CSE Technical Reports

As modern storage systems have grown in size and complexity, RAID-6 is poised to replace RAID-5 as the dominant form of RAID architectures due to its ability to protect against double disk failures. Many excellent erasure codes specially designed for RAID-6 have emerged in recent years. However, all of them have limitations. In this paper, we present a class of near perfect erasure codes for RAID-6, called the Ultimate codes. These codes encode, update and decode either optimally or nearly optimally, regardless of what the code length is. This implies that utilizing these codes we can build highly efficient and …

S-Code: Lowest Density Mds Array Codes For Raid-6, Zhijie Huang, Hong Jiang, Ke Zhou, Yuhong Zhao, Chong Wang

CSE Technical Reports

RAID, a storage architecture designed to exploit I/O parallelism and provide data reliability, has been deployed widely in computing systems as a storage building block. In large scale storage systems, in particular, RAID-6 is gradually replacing RAID-5 as the dominant form of disk arrays due to its capability of tolerating concurrent failures of any two disks. MDS (maximum distance separable) array codes are the most popular erasure codes that can be used for implementing RAID-6, since they enable optimal storage efficiency and efficient encoding and decoding algorithms. In this paper, we propose a new class of MDS array codes called …

Developing A Measure Of Scientific Literacy For Middle School Students, Helenrose Fives, Mark Nicolich, Amanda Birnbaum, Wendy Huber

Department of Public Health Scholarship and Creative Works

Scientific literacy reflects “a broad and functional understanding of science for general education purposes” (DeBoer, 2000, p. 594). Herein, we present the ongoing development of the Scientific Literacy Assessment (SLA), a work‐in‐progress measure to assess middle school students' (ages 11–14) scientific literacy. The SLA includes a selected response measure of students’ demonstrated scientific literacy (SLA‐D) and a motivation and beliefs scale based on existing measures of self‐efficacy, subjective task value, and personal epistemology for science (SLA‐MB). Our theoretical conceptualization of scientific literacy guided the development of our measure. We provide details from three studies: Pilot Study 1 (n = …

Single Event Mitigation For Aurora Protocol Based Mgt Fpga Designs In Space Environments, Alexander Stanley Harding

Theses and Dissertations

This work has extended an existing Aurora protocol for high-speed serial I/O between FPGAs to provide greater fault recovery in the presence of high-energy radiation. To improve on the Aurora protocol, additional resets that affect larger portions of the system were used. Detection for additional error modes that occurred but were not detected by the Aurora protocol was designed. Radiation testing was performed on the Aurora protocol with the additional mitigation hardware. The test gathered large amounts of data on the various error modes of the Aurora protocol and how the additional mitigation circuitry affected the system. The test results …

I Found It On The Internet...: The Webmd Phenomenon & The Patient-Provider Relationship, Jessica Rivetz

Honors Theses

Over the past few decades, the Internet has become a popular channel through which patients can seek health information. Even a decade ago, 73 million American adults admitted to being “health information seekers.” It is well known that effective communication and a strong relationship between patients and providers result in higher patient satisfaction and better outcomes; but patients are often dissatisfied. The increasing public availability of health information online is adding yet another dimension to the patient-provider relationship that neither party is fully equipped to handle. Using nationally representative HINTS data from 2003, 2005, 2007 and 2011, this study evaluates …

Stochastic Modeling Of A Concrete Mixture Plant With Preventive Maintenance, Ashish Kumar, Monika Saini, S. C. Malik

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, a stochastic model for concrete mixture plant with Preventive Maintenance (PM) is analyzed in detail by using a supplementary variable technique. In a concrete mixture plant eight subsystems are arranged in a series. The system goes under PM after a maximum operation time and work as new after PM. The time to failure of each subsystem follows a negative exponential distribution while PM and repair time distributions are taken as arbitrary. A sufficient repair facility is provided to the system for conducting PM and repair of the system. Repair, maintenance and switch devices are perfect. All random …

Development Of A Method For Incorporating Fault Codes In Prognostic Analysis, Eric Allen Strong

Doctoral Dissertations

Information from fault codes associated with a component may be used as an indicator of its health. A fault code is defined as a timestamp at which a component is not operating according to recommended guidelines. The type of fault codes which are relevant for this analysis represent mild or moderate deviations from normal behavior, rather than those requiring immediate repair. Potentially, fault codes may be used to determine the Remaining Useful Life (RUL) of a component by predicting its failure time, which will improve safety and reduce maintenance costs associated with the component. In this dissertation, methods have been …

What We Can And Cannot (Yet) Do With Functional Near Infrared Spectroscopy, Megan K. Strait, Matthias Scheutz

Computer Science Faculty Publications and Presentations

Functional near infrared spectroscopy (NIRS) is a relatively new technique complimentary to EEG for the development of brain-computer interfaces (BCIs). NIRS-based systems for detecting various cognitive and affective states such as mental and emotional stress have already been demonstrated in a range of adaptive human–computer interaction (HCI) applications. However, before NIRS-BCIs can be used reliably in realistic HCI settings, substantial challenges oncerning signal processing and modeling must be addressed. Although many of those challenges have been identified previously, the solutions to overcome them remain scant. In this paper, we first review what can be currently done with NIRS, specifically, NIRS-based …

A Reliability Prediction Method For Phase-Change Devices Using Optimized Pulse Conditions, Martin Jared Barclay

Boise State University Theses and Dissertations

Owing to the outstanding device characteristics of Phase-Change Random Access Memory (PCRAM) such as high scalability, high speed, good cycling endurance, and compatibility with conventional complementary metal-oxide-semiconductor (CMOS) processes, PCRAM has reached the point of volume production. However, due to the temperature dependent nature of the phase-change memory device material and the high electrical and thermal stresses applied during the programming operation, the standard methods of high-temperature (Temperature > 125 °C) accelerated retention testing may not be able to accurately predict bit sensing failures or determine slight pulse condition changes needed if the device were to be …

The Reliability Of Eyewitness Testimony, Nathan Roberts

Senior Honors Theses

As perhaps the single most effective method of proving the elements of a crime, eyewitness testimony has been vital to the trial process for centuries. However, the reliability of eyewitness testimony has recently come into question with the work of organizations such as The Innocence Project, which works to exonerate the wrongfully convicted. This thesis examines previous experiments concerning eyewitness testimony as well as court cases in which eyewitnesses provided vital evidence in order to determine the reliability of eyewitness testimony as well as to determine mitigating or exacerbating factors contributing to a lack of reliability.

Risk-Based Bridge Inspection Practices, Rebecca Reising

Open Access Theses

Improving bridge safety, reliability, and the allocation of bridge inspection resources are the goals of the proposed risk based bridge inspection practices. Currently, most bridges in the United States are inspected at a fixed calendar interval of 24 months, without regard to the condition of the bridge. Newer bridges with little or no damage are inspected with the same frequency as older, more deteriorated bridges thus creating inefficiency in the allocation of inspection resources. Because of limited resources, it is not possible to spend the necessary time examining bridges that are in poor condition and require extra attention since equal …
