An Analysis Of Safety Culture & Safety Training: Comparing The Impact Of Union, Non-Union, And Right To Work Construction Venues, Harry Miller Csp, Tara Hill, Kris Mason, John S. Gaal Edd

Online Journal for Workforce Education and Development

The construction industry is one of the most dangerous sectors of the US economy. As such, the safety attitudes and climate within small (residential) contracting firms may play a role in providing a safe culture and working environment. The intent of this practitioner-based research study is to compare and determine if there is a difference in safety practices—based on documented field inspections and their related original number of violations observed by OSHA—between union residential carpentry contractors in the St. Louis area and:

1) non-union residential carpentry contractors in the St. Louis area;

2) non-union residential carpentry contractors across Missouri; and …

Issue Brief: Saving By Mitigating, University Of Louisville, New England Environmental Finance Center

Sustainable Communities Capacity Building

Natural disasters can cause loss of life, inflict damage to buildings and infrastructure, and have devastating consequences for a community’s economic, social, and environmental well-being. Hazard mitigation means reducing damages from disasters.

Local governments have the responsibility to protect the health, safety, and welfare of their citizens. Proactive mitigation policies and actions help reduce risk and create safer, more disaster-resilient communities. Mitigation is an investment in your community’s future safety, equity, and sustainability.

On The Primitives Of Causality: From The Semantics Of Agonist And Antagonist To Models Of Accident Causation And System Safety, Loïc Brevault, Francesca Favaro, Joseph Saleh

Faculty Publications

Controversial discussions on causality have been present in ancient philosophy since the days of Aristotle. Despite the use of this concept in numerous subjects, there is no consensus on the definition of causality and its possible mathematization. Many authors have analyzed the relation between causes and effects; the predominant school of thought reduces causation to a physical relation (either deterministic or probabilistic) between two events. The distinction between causes and consequences is not always clear and meaningful as different “layers of understanding” may be applied to the notion of causality. From this point of view the cause-effect implication relation can …

Stochastic Simulation Of Multiple-Station Ground Motions And Its Applications, Taojun Liu

Electronic Thesis and Dissertation Repository

Approaches to simulate single- and multiple-component multiple-station ground motion records with target spatial coherency and spatial correlation structures are developed for scenario events in this study. To develop the approaches, spatial correlation of the Fourier amplitude spectrum for a random orientation and for two orthogonal directions is assessed, and empirical equations are suggested. Moreover, spatial coherency of ground motions for two orthogonal horizontal directions is estimated using actual records from seven seismic events. Empirical coherency function is suggested for the components of records in two orthogonal horizontal directions at single and multiple recording stations. It was also found that the …

Entropy Applications In Industrial Engineering, Saeed Zamiri Marvizadeh

Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

Entropy is a fundamental measure of information content which has been applied in a wide variety of fields. We present three applications of entropy in the industrial engineering field: dispatching of Automatic Guided Vehicles (AGV), ranking and selection of simulated systems based on the mean performance measure, and comparison between random variables based on cumulative probability distributions.

The first application proposes three entropy-based AGV dispatching algorithms. We contribute to the body of knowledge by considering the consequence of potential AGV moves on the load balance of the factory before AGVs are dispatched. Kullback-Leibler directed divergence is applied to measure the …

A Prototype Decision Support Tool For Ballast Water Risk Management Using A Combination Of Hydrodynamic Models And Agent-Based Modelling, Fleming T. Hansen, Jesper H. Andersen, Michael Potthof, Thomas Uhrenholdt, Hong D. Vo, Olof Lindén

NSBWO

We report the development of a prototype Decision Support Tool (DST) for modelling the risks of spreading of non-indegenous invasive species via ballast water. The DST constitutes of two types of models: A 3D hydrodynamical model calculates the currents in the North Sea and Danish Straits, and an agent-based model estimates the dispersal of selected model organisms with the prevailing currents calculated by the 3D hydrodynamical model. The analysis is concluded by a post processing activity, where scenarios of dispersal are combined into an interim estimate of connectivity within the study area. The latter can be used as a tool …

National Infrastructure Protection Priorities For Nuclear Electromagnetic Pulse (Emp) And Solar Storm Geomagnetic Disturbance Catastrophes, George H. Baker Iii

George H Baker

The Commission to Assess the Threat to the United States from Electromagnetic Pulse Attack has provided a compelling case for protecting civilian infrastructure against the effects of EMP and geomagnetic disturbances (GMD) caused by severe solar storms. Similar to protecting critical infrastructure against any hazard, it will be important to take a risk-based priority approach for these two electromagnetic threats, recognizing that it will be fiscally impracticable to protect everything. In this regard, EMP and GMD are particularly challenging in that they interfere with electrical and electronic data, control, transmission, and communication systems organic to nearly all critical infrastructures, simultaneously, …

Special Section Editorial: Risk, Complexity And Sustainability, Lindsay Robertson, Katina Michael

Professor Katina Michael

This special section is dedicated to risk as understood within our society, in which we depend upon increasingly complex and interconnected technologies for even our most basic needs - water, food, shelter, electricity, gas, sewage, communications, and banking.

Natural disasters and their impact on vital services has been a research area that has flourished, especially since the 2004 Indian Ocean Tsunami that claimed hundreds of thousands of lives in South Asia. Out of this research has come forth a plethora of strategies for addressing short term and geographically defined disasters. While such disaster preparedness systems are vital to minimise the …

Extremes Of Nonlinear Vibration: Comparing Models Based On Moments, L-Moments, And Maximum Entropy, Steven R. Winterstein, Cameron A. Mackenzie

Cameron A. MacKenzie

Wind and wave loads on offshore structures show nonlinear effects, which require nonGaussian statistical models. Here we critically review the behavior of various nonGaussian models. We first survey moment-based models; in particular, the four-moment “Hermite” model, a cubic transformation often used in wind and wave applications. We then derive an “L-Hermite” model, an alternative cubic transformation calibrated by the response “L-moments” rather than its ordinary statistical moments. These L-moments have recently found increasing use, in part because they show less sensitivity to distribution tails than ordinary moments. We find here, however, that these L-moments may not convey sufficient information to …

Reliability Analysis Of Social Networks, Kellie R. Schneider

Graduate Theses and Dissertations

The primary focus of this dissertation is on the quantification of actor interaction and the dissemination of information through Social networks. Social networks have long been used to model the interactions between people in various Social and professional contexts. These networks allow for the explicit modeling of the complex interrelations between relevant individuals within an organization and the role they play in the decision making process. This dissertation considers Social networks represented as network flow models in which actors have the ability to provide some level of influence over other actors within the network. The models developed incorporate performance metrics …

Capturing Creative Program Management Best Practices, Brandon Keller, Joseph R. Wirthlin

Faculty Publications

This research attempted to capture the creative aspects of government program management in three specific areas: efficiently navigating oversight, capturing the intent of regulations, and developing innovative risk management practices. Respected acquisition leaders with diverse backgrounds and experiences were interviewed with ranks ranging from 0-6 to 0-8 and GS-15 to SES. Several contractor interviews were conducted for specific purposes. The data were iteratively coded and analyzed using ATLAS.ti. The results were categorized into four themes, each with three sub-elements. Differences between respondents with program director experience and those with rapid acquisition experience are discussed. A survey was then distributed to …

Fuzzy Expert-Cocomo Risk Assessment And Effort Contingency Model In Software Project Management, Ekananta Manalif

Electronic Thesis and Dissertation Repository

Software development can be considered to be the most uncertain project when compared to other types of projects due to the uncertainty in the customer requirements, the complexity of the process, and the intangible nature of the product. In order to increase the likelihood of success in managing a software project, the project manager(s) must invest more time and effort in the project planning phase. The two main activities in project planning phase are effort estimation and risk management which has to be executed together because the accuracy of the effort estimation is highly dependent on the size and nature …

Investigation Into Risk And Uncertainty: Identifying Coefficient Of Variation Benchmarks For Air Force Acat I Programs, Shaun T. Carney

Theses and Dissertations

Previous DoD cost growth studies found typical cost growth in defense acquisitions is around forty-six to sixty percent of the original estimate. The research in this study addresses the identification of risk and uncertainty benchmarks by providing decision makers with coefficient of variation ranges for cost estimates. The study recommends coefficient of variation (CV) ranges for Air Force Acquisition programs, determines if different CV ranges should be used based on platform type, and determines if CV decreases over the course of the program's acquisition lifecycle. The analysis found that the Air Force should enhance the CV review process to ensure …

From Cyber Terrorism To State Actors’ Covert Cyber Operations, Jan Kallberg, Bhavani Thuraisingham

Jan Kallberg

Historically, since the Internet started to become a common feature in our lives, hackers have been seen as a major threat. This view has repeatedly been entrenched and distributed by media coverage and commentaries through the years. Instead the first twenty year of the Internet was acceptably secure, due to the limited abilities of the attackers, compared to the threat generated from a militarized Internet with state actors conducting cyber operations. In reality, the Internet have a reversed trajectory for its security where it has become more unsafe over time and moved from a threat to the individual to a …
