Automating Ciri Ratings Of Human Rights Reports Using Gate, Joshua M. Joiner

UNF Graduate Theses and Dissertations

This thesis involves parsing document-based reports from the United States Human Rights Reports and rating the human practices for various countries based on the CIRI (Cingranelli-Richards) Human Rights Data Project dataset. The United States Human Rights Reports are annual reports that cover internationally recognized human rights practices regarding individual, civil, political, and worker rights. Students, scholars, policymakers, and analysts used the CIRI data for practical and research purposes.

Multi-Robot Complete Coverage Using Directional Constraints, Stefanus Malan

CCE Theses and Dissertations

Complete coverage relies on a path planning algorithm that will move one or more robots, including the actuator, sensor, or body of the robot, over the entire environment. Complete coverage of an unknown environment is used in applications like automated vacuum cleaning, carpet cleaning, lawn mowing, chemical or radioactive spill detection and cleanup, and humanitarian de-mining.

The environment is typically decomposed into smaller areas and then assigned to individual robots to cover. The robots typically use the Boustrophedon motion to cover the cells. The location and size of obstacles in the environment are unknown beforehand. An online algorithm using sensor-based …

Determining Vulnerability Using Attack Graphs: An Expansion Of The Current Fair Model, Beth M. Anderson

EWU Masters Thesis Collection

Factor Analysis of Information Risk (FAIR) provides a framework for measuring and understanding factors that contribute to information risk. One such factor is FAIR Vulnerability; the probability that an event involving a threat will result in a loss. An asset is vulnerable if a threat actor’s Threat Capability is higher than the Resistance Strength of the asset. In FAIR scenarios, Resistance Strength is currently estimated for entire assets, oversimplifying assets containing individual systems and the surrounding environment. This research explores enhancing estimations of FAIR Vulnerability by modeling interactions between threat actors and assets through attack graphs. By breaking down the …

Estimating The Optimal Cutoff Point For Logistic Regression, Zheng Zhang

Open Access Theses & Dissertations

Binary classification is one of the main themes of supervised learning. This research is concerned about determining the optimal cutoff point for the continuous-scaled outcomes (e.g., predicted probabilities) resulting from a classifier such as logistic regression. We make note of the fact that the cutoff point obtained from various methods is a statistic, which can be unstable with substantial variation. Nevertheless, due partly to complexity involved in estimating the cutpoint, there has been no formal study on the variance or standard error of the estimated cutoff point.

In this Thesis, a bootstrap aggregation method is put forward to estimate the …

Staff Education Module For Bar Code Medication Administration, Francoise Juste

Walden Dissertations and Doctoral Studies

Bar Code Medication Administration (BCMA) is a technology-supported nursing tool that has become the standard of practice for medication administration. When used effectively and efficiently, this tool has the potential to reduce medication errors in acute care settings. In a pediatric unit at a major urban hospital in the northeast region of the United States, the absence of a BCMA nursing staff educational module affected the use of this safety tool leading to an increase of medication errors. The purpose of this DNP project was to develop a comprehensive educational module to promote BCMA in the pediatric unit of the …

User Interface Challenges Of Banking Atm Systems In Nigeria, Felix Chukwuma Aguboshim

Walden Dissertations and Doctoral Studies

The use of banking automated teller machine (ATM) technological innovations have significant importance and benefits in Nigeria, but numerous investigations have shown that illiterate and semiliterate Nigerians do not perceive them as useful or easy-to-use. Developing easy-to-use banking ATM system interfaces is essential to accommodate over 40% illiterate and semiliterate Nigerians, who are potential users of banking ATM systems. The purpose of this study was to identify strategies software developers of banking ATM systems in Nigeria use to create easy-to-use banking ATM system interfaces for a variety of people with varying abilities and literacy levels.

Patient Satisfaction Management In Office Visits And Telehealth In Health Care Technology, Todd Price

Walden Dissertations and Doctoral Studies

Telehealth and remote medical treatments have begun to be more commonly used in healthcare systems. Researchers have theorized that providers' abilities to treat patients are not directly tied to the proximity of the patient to the doctor, but by the identification and treatment of the patient's symptoms. Although the treatment and cure rates are being established within individual health systems and professional medical associations, empirical research is lacking regarding patient satisfaction with this remote treatment situation. The purpose of this quantitative study was to address this gap by examining satisfaction ratings of patients between virtual provider visits and face-to-face provider …
