Managing The Wear Of Heavy Construction Equipment Steel Track Undercarriage By Soil Sand Content, Frederick Ashburn Rich May 2020

Managing The Wear Of Heavy Construction Equipment Steel Track Undercarriage By Soil Sand Content, Frederick Ashburn Rich

All-Inclusive List of Electronic Theses and Dissertations

Heavy construction equipment owners and managers have few predictive tools that can estimate wear rate of undercarriage track propulsion systems working in various soil types and changing operational conditions. Managing the timely maintenance of these track systems is critical for they represent over half of the non-fuel operating cost of the equipment fleet. Understanding the major influencing factors that impact undercarriage system wear rate can help determine the most economical time to stop a machine for track maintenance thus positively impacting the equipment’s return on investment (ROI). This research analyzed the population of track type dozers in the eastern half …


Technology Threat Avoidance Factors As Predictors Of Risky Cybersecurity Behavior Within The Enterprise, Andrew R. Gillam May 2019

Technology Threat Avoidance Factors As Predictors Of Risky Cybersecurity Behavior Within The Enterprise, Andrew R. Gillam

All-Inclusive List of Electronic Theses and Dissertations

Recent research of information technology (IT) end-user cybersecurity-related risky behaviors has focused on items such as IT user decision-making, impulsiveness, and internet use as predictors of human cyber vulnerability. Theories which guide user human behavioral intent, such as protection motivation theory (PMT, introduced by Rogers, 1975) and technology threat avoidance theory (TTAT, introduced by Liang and Xue, 2009) have not been widely investigated as antecedents of risky cybersecurity behavior (RScB). This dissertation describes exploratory research that analyzed and evaluated PMT/TTAT factors as predictors of RScB by enterprise IT users. This work uniquely contributes to the literature by investigating associations between …


Incorporating Lean Non-Value Added Variants Into A Method Of Determining Stakeholder Salience For First-Line Manager Decision Making, Bruce H. Bader Dec 2017

Incorporating Lean Non-Value Added Variants Into A Method Of Determining Stakeholder Salience For First-Line Manager Decision Making, Bruce H. Bader

All-Inclusive List of Electronic Theses and Dissertations

This research brings together two streams of thought for first-line manager decision-making. The first is the quality system model, in particular, Lean operations. The second is Stakeholder Theory. Both streams have been identified as ways to improve value of the organization. Previous studies disagree regarding whether Lean and Stakeholder theory can work together. The potential problem of having a poor balance of Stakeholders and Lean waste is that exclusive focus on one may result in less awareness of the other, in which case value can be lost by the organization. This research investigates if both Lean waste and Stakeholder salience …


Analytical Modeling And Feasibility Study For Adoption Of Renewable Energy Sources In A Single Family Dwelling, Jimmy B. Linn Dec 2014

Analytical Modeling And Feasibility Study For Adoption Of Renewable Energy Sources In A Single Family Dwelling, Jimmy B. Linn

All-Inclusive List of Electronic Theses and Dissertations

In the last four or five decades, increased political and social pressure has been placed on commercial and residential consumers to reduce consumption of fossil fuels and invest in alternative methods of energy production for electricity, heating and cooling. Commercially, wind turbines and photovoltaic energy production equipment has sprung up all over the country. Other forms of energy production such as hydroelectric and geothermal energy production facilities have also been built. During this time however, very few residential ‘green energy’ investments have been made. Only in recent years have residential home owners begun to “wet their feet” on ‘green’ energy …


Assessment Of Future Employment And Competency Skills In Building Information Modeling: A Delphi Study, Joseph A. Raiola Iii Aug 2014

Assessment Of Future Employment And Competency Skills In Building Information Modeling: A Delphi Study, Joseph A. Raiola Iii

All-Inclusive List of Electronic Theses and Dissertations

Many mainstream architecture, engineering, and construction (AEC) professionals are using Building Information Modeling (BIM). Although more and more firms are using BIM and this trend is forecast to continue, it is unclear what skills and competencies a construction manager will need in five years related to BIM. This research aims to answer that question through the use of a Delphi panel comprised of AEC professionals. The panel consists of members with the following qualifications: a minimum of eight years industry or academic experience or a combination of the two, a minimum of three years BIM experience, and membership in a …
