Evaluating Human Factors In The Commercial Pilot-Airplane Airman Certification Standards, Alaba Gabriel Idowu

Graduate Student Works

This research aimed to identify risk management elements in the Commercial Pilot-Airplane Airman Certification Standards (ACS), and to evaluate tasks relating to or involving human factors. The investigation examined the risk management elements under each task in the Commercial Pilot-Airplane ACS and classified them under the preconditions for unsafe acts of the Human Factors Analysis Classification System (HFACS). The method of investigation was a qualitative research approach to determine the human factors element prevalent in the Commercial Pilot-Airplane ACS. Three research questions were stated: (1) Which factor under the preconditions for unsafe of HFACS has the highest number of tasks …

Examination Of The Relationship Between External Environmental Conditions And Construction Project Failures In Countries Of Northern Africa, Rex W. Mols

Doctoral Dissertations and Projects

The construction industry is an essential and supportive pillar of national economies in Northern Africa making construction project management a dynamic arena. Construction project success is dependent on how well project managers recognize and manage project constraints versus negative risk impacts. The purpose of this qualitative research was to explore and describe the impacts between external environmental conditions and construction project failures in countries of Northern Africa. Data was sourced from construction project managers that operate within this region. Data collected focuses on the interdependencies between negative risk impacts from external environmental conditions and construction project failures. An analysis of …

On The Potential, Feasibility, And Effectiveness Of Chat Bots In Public Health Research Going Forward, Stanley Mierzwa, Samir Souidi, Tammy Allen

Center for Cybersecurity

This paper will discuss whether bots, particularly chat bots, can be useful in public health research and health or pharmacy systems operations. Bots have been discussed for many years; particularly when coupled with artificial intelligence, they offer the opportunity of automating mundane or error-ridden processes and tasks by replacing human involvement. This paper will discuss areas where there are greater advances in the use of bots, as well as areas that may benefit from the use of bots, and will offer practical ways to get started with bot technology. Several popular bot applications and bot development tools along with practical …

Beyond K-Anonymity: A Decision Theoretic Framework For Assessing Privacy Risk, Guy Lebanon, Monica Scannapieco, Mohamed Fouad, Elisa Bertino

Cyber Center Publications

An important issue any organization or individual has to face when managing data containing sensitive information, is the risk that can be incurred when releasing such data. Even though data may be sanitized before being released, it is still possible for an adversary to reconstruct the original data using additional information thus resulting in privacy violations. To date, however, a systematic approach to quantify such risks is not available. In this paper we develop a framework, based on statistical decision theory, that assesses the relationship between the disclosed data and the resulting privacy risk. We model the problem of deciding …

Metrics And Models For Cost And Quality Of Component-Based Software, Sahra Sedigh, Arif Ghafoor, Raymond A. Paul

Electrical and Computer Engineering Faculty Research & Creative Works

Quality and risk concerns currently limit the application of commercial off-the-shelf (COTS) software components to non-critical applications. Software metrics can quantify factors contributing to the overall quality of a component-based system, and models for tradeoffs between cost and various aspects of quality can guide quality and risk management by identifying and eliminating sources of risk. This paper discusses metrics and models that can be used to alleviate quality concerns for COTS-based systems, enabling the use of COTS components in a broader range of applications.

Metrics-Based Framework For Decision Making In Cots-Based Software Systems, Sahra Sedigh, Arif Ghafoor, Raymond A. Paul

Electrical and Computer Engineering Faculty Research & Creative Works

The growing reliance on Commercial-Off-The-Shelf (COTS) components for developing large-scale projects introduces a new paradigm in software Engineering; which requires the design of new software development and business processes. Large scale component reuse leads to savings in development resources, enabling these resources to be applied to areas such as quality improvement. These savings come at the price of integration difficulties, performance constraints, and incompatibility of components from multiple vendors. Relying on COTS components also increases the system's vulnerability to risks arising from third-party development, which can negatively affect the quality of the system, as well as causing expenses not incurred …

Radiation Resistance Testing Of Mosfet And Cmos As A Means Of Risk Management, Akira Tokuhiro, Massimo F. Bertino

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

Whether for military, research (space, accelerator physics) and/or civilian use, risk avoidance against radiation-induced damage is not possible with COTS parts. Thus the sensible approach is risk management. We recommend a sensible risk management approach as follows: 1) know the radiation environment of the intended application to the extent possible; 2) know the effects of ionizing radiation on the component(s) of interest; 3) know the requirements of the application; 4) identify the candidate or chosen components; 5) test the components; 6) design-in safety factor margins to the extent possible.

Software Engineering Metrics For Cots-Based Systems, Sahra Sedigh, Arif Ghafoor, Raymond A. Paul

Electrical and Computer Engineering Faculty Research & Creative Works

The paradigm shift to commercial off-the-shelf components appears inevitable, necessitating drastic changes to current software development and business practices. Quality and risk concerns currently limit the application of COTS based system design to noncritical applications. New approaches to quality and risk management will be needed to handle the growth of CBSs. Our metrics based approach and software engineering metrics can aid developers and managers in analyzing the return on investment in quality improvement initiatives for CBSs. These metrics also facilitate the modeling of cost and quality, although we need more complex models to capture the intricate relationships between cost and …

Roadway Related Tort Liability And Risk Management: 3rd Edition, Daniel S. Turner, Kenneth R. Agent

Kentucky Transportation Center Research Report

This training material has been prepared to address the tort liability problems faced by the Kentucky Transportation Cabinet and Kentucky local governments. The workbook defines the problem by reviewing the national picture of growing numbers of suits and escalating financial losses from suits against highway agencies.

The workbook also sets out solutions, and reviews actions which can decrease the exposure of highway agencies to these suits. This risk management concept is emphasized throughout the workbook.

Tort Liability Related To Highways In Kentucky, Kenneth R. Agent, Jerry G. Pigman

Kentucky Transportation Center Research Report

An objective of this study was to review and analyze claims made against the Kentucky Transportation Cabinet through the Board of Claims. Another objective was to review the current state-of-the-art related to tort liability and highway agencies. This was accomplished by reviewing the literature and contacting other state highway agencies. Using information obtained from these various sources, recommendations were made relating to the establishment of an effective risk management program.

Information from Board of Claims cases was obtained for the years 1981 through 1989 and then analyzed. This information included the date of the claim, the county where the action …
