Community-Of-Interest (Coi) Model-Based Languages Enabling Composable Net-Centric Services, Andreas Tolk, Saikou Y. Diallo

Computational Modeling & Simulation Engineering Faculty Publications

Net-centric services shall be designed to collaborate with other services used within the supported Community of Interest (COI). This requires that such services not only be integratable on the technical level and interoperable on the implementation level, but also that they are composable in the sense that they are semantically and pragmatically consistent and able to exchange information in a consistent and unambiguous way.

In order to support Command-and-Control with Composable Net-centric Services, the human-machine interoperation must be supported as well as the machine-machine interoperation. This paper shows that techniques of computer linguistic can support the human-machine interface by structuring …

A Synthesised Knowledge Mapping Framework To Embed A Km Strategy Using Topic Maps And Wikis: The Tao Of Wiki, Colman A.J. Mcmahon

Dissertations

Just getting started with knowledge management can be difficult enough for many organisations, however the real challenge is actually how to embed the new practices. The expression "Success is a journey, not a destination" is particularly apt for KM. This research presents findings from stakeholder analyses carried out in an Irish government agency. The agency has been on its KM journey for nearly four years and has attempted to implement a comprehensive and full-scale strategy. The findings indicate that KM practices have not yet become fully embedded in the organisation. This research uncovers some of the reasons why not. In …

Value Mapping Framework Involving Stakeholders For Supply Chain Improvement When Implementing Information Technology Projects, Karla Moore

Electronic Theses and Dissertations

Successful Supply Chain Management (SCM) depends on how well an organization performs internal and external communications with trading partners, executes the logistics component, and understands/monitors related costs of conducting its business. The use of information technology (IT) is considered a prerequisite for the effective control of today's complex supply chains. Increased communication technology has redefined how businesses work together, raised customer expectations, and placed new demands on supply chain performance. IT components with proven and rapid return-on-investment are favored to support critical supply chain processes such as leaner manufacturing processes, consumer-driven supply chains, and customer responsiveness. The use of IT …

A Meta Analysis Of Critical Success Factors For Computer Technology Projects, Ross A. Baker

Theses

Project managers are continually in pursuit of a magic formula that will deliver a successful project. Companies arc interested in formulas for project success because billions of dollars arc wasted each year, in U.S.A. Information Technology projects alone. through poorly managed or failed projects. Failing projects arc not only bad for the individual project team members, but a failed project's impacts emanate outward to cause companies to decline or die. In addition, the targeted customers who receive inferior products, late products, or no products at all (due to project failures) are significantly impacted as well. Because failed computer technology projects …

Browse all Theses and Dissertations

As businesses consolidate and modernize their operations, the impact on their network and computing infrastructure is a major consideration. In this thesis, discrete event simulation is used to show how implementation of an Enterprise Resource Planning (ERP) system can impact network performance and ultimately affect end-users. More specifically, the model simulates the flow of data packets across a network, through a Service Delivery Point (SDP), which is comprised of routers, switches, and firewalls that connect a Local Area Network to a Wide Area Network.

The model was used to run to determine the affect of more network traffic and additional …

How Are Nasa Engineers Motivated? An Analysis Of Factors That Influence Nasa Goddard Engineers’ Level Of Motivation, Howard Eric Kea

Antioch University Dissertations & Theses

NASA is an organization known for pushing the envelope of engineering and scientific achievement. It can be argued that engineers working for NASA are intrinsically highly motivated due to the nature of the work and the mission of NASA. This study explores how supervisor behaviors, both intrinsic and extrinsic and demographic factors influence motivation of NASA Goddard engineers in their current environment. Recent Congressional and Office of Management and Budget (OMB) policies, such as full cost accounting, levy strict oversight of project spending. As a result of these policies, NASA engineers must now focus their attention on getting assigned work …

Shift Work In The Long-Termcare Industry : An Examination Of Organizational And Individual Factors That Influence Employee Outcomes, Kristin Elizabeth Charles

Dissertations and Theses

The long-term care (LTC) industry provides medical and social services in facility-based settings to the elderly, chronically ill, and disabled. With the aging of the United States population, the need for LTC workers is expected to drastically increase in the next decade. However, the industry faces a significant staffing shortage. One potential cause of staffing problems in LTC is working non-standard work schedules. Because of the need to provide around the clock care, LTC employees often work non-standard shifts, long hours, night work, and over weekends and holidays. Although many studies have examined health and sleep-related outcomes associated with non-standard …

Global-Change Scenarios: Their Development And Use, Edward Parson, Virginia Burkett, Karen Fisher-Vanden, David Keith, Linda Mearns, Hugh Pitcher, Cynthia Rosenzweig, Mort Webster

United States Department of Energy: Publications

A scenario is a description of potential future conditions produced to inform decision-making under uncertainty. Scenarios can help inform decisions that involve high stakes and poorly characterized uncertainty, which may thwart other, conventional forms of analysis or decision support. Originally developed to study military and security problems, scenarios are now widely used for strategic planning and assessment in businesses and other organizations, and increasingly to inform planning, analysis, and decision-making for environmental issues, including climate change.
Scenarios can serve many purposes. They can help inform specific decisions, or can provide inputs to assessments, models, or other decision-support activities when these …

Social Network Structures In Open Source Software Development Teams, Y. Long, Keng Siau

Research Collection School Of Computing and Information Systems

Drawing on social network theories and previous studies, this research examines the dynamics of social network structures in open source software (OSS) teams. Three projects were selected from SourceForge.net in terms of their similarities as well as their differences. Monthly data were extracted from the bug tracking systems in order to achieve a longitudinal view of the interaction pattern of each project. Social network analysis was used to generate the indices of social structure. The finding suggests that the interaction pattern of OSS projects evolves from a single hub at the beginning to a corel periphery model as the projects …

This is needed to comprehend how issues such as airlift funding, current and future force reductions, and manning and experience levels may impact future MC rates for air mobility assets. Existing tools do not incorporate several key variables that the literature suggests are related to MC rates. Using a longitudinal approach, this thesis combines C-17 aircraft data with a structural equations modeling approach to evaluate …

Job Insecurity And Work-Family Conflict: The Organizational, Situational, And Individual Influences On The Job Strain Process, Khatera Sahibzada

Dissertations and Theses

Globalization, new technologies, downsizing, and a shift from manufacturing to service-based economies have led to an increase in job insecurity, resulting in deleterious effects on employee work attitudes and behaviors. However, the literature has failed to examine the impact of job insecurity on work-family outcomes. Therefore, the purpose of the present study was to examine the relationship between job insecurity and work-family conflict. The specific research questions addressed were: (a) does job strain mediate the relationship between job insecurity and work-family conflict? and (b) is the relationship between job insecurity and work-family conflict moderated by individual, situational and organizational perceptions? …

A Graph Theoretic Analysis Of The Effects Of Organizational Structure On Employee Social Networks, John R. Hutzel

Theses and Dissertations

A simulation technique was used to investigate the impacts of organizational structure on an organization's social network. By simulating personnel in an organization as vertices in a graph and the aging of the corporation as the aging of the same graph, the maturation of an organization was realized. The characteristic path length of the graph was measured after each year returning an optimistic average organizational distance. Results include the finding that, per this model, an organization's characteristic path length can drop over 50% in a 20 year period with consideration of edges of all strengths. Next a series of random …

Patterns In Team Communication During A Simulation Game, David M. Baca, Ray Luechtefeld, Steve Eugene Watkins

Engineering Management and Systems Engineering Faculty Research & Creative Works

The development of communication skills is a necessary preparation for effective engineering teamwork. Argyris' "Theory of Action" provides a framework for understanding patterns in team dialogue. Students can benefit from an awareness of these patterns. The theory highlights the detection and correction of errors by sharing information during group collaboration and interactions. Quality decision-making can be enhanced when members of a team develop high degrees of openness and interdependence. Quality decision-making can be diminished when members of a team regulate the information shared within the team. This work analyzes team interactions from simulation games used in an interdisciplinary engineering course …

An Assessment Of Alignment Between Project Complexity And Project Management Style, Alper Camci

Electronic Theses and Dissertations

The main drivers for this research are the complexities associated with the project management and an organization's project management style in dealing with these complexities. This research aims to demonstrate that alignment between project complexity and project management style increases project performance and decreases project issues, and also, with increased project issues, project performance deteriorates. In order to test these claims, this research developed measures for assessing project complexity, project management styles and project issues by employing a survey of project management professionals. The measure for project complexity is based on a taxonomy with four categories: organizational complexity, product complexity, …

Competent Program Evolution, Doctoral Dissertation, December 2006, Moshe Looks

All Computer Science and Engineering Research

Heuristic optimization methods are adaptive when they sample problem solutions based on knowledge of the search space gathered from past sampling. Recently, competent evolutionary optimization methods have been developed that adapt via probabilistic modeling of the search space. However, their effectiveness requires the existence of a compact problem decomposition in terms of prespecified solution parameters. How can we use these techniques to effectively and reliably solve program learning problems, given that program spaces will rarely have compact decompositions? One method is to manually build a problem-specific representation that is more tractable than the general space. But can this process be …

Today’S Dot And The Quest For More Accountable Organizational Structures, Lenahan O'Connell, Juita-Elena (Wie) Yusuf, Merl Hackbart, Donald L. Hartman, Candice Wallace, Doug Kreis

Kentucky Transportation Center Research Report

This study investigates the impact of DOT organizational structures on effective transportation planning and performance. A review of the 50 state DOT authorizing statutes and DOT organizational charts found minimal differences in organizational structures among the states. However, 37 states have quasi-independent commissions (sometimes called boards, or councils.) A statistical analysis showed that the commission states have higher Government Performance Project (GPP) scores than the non-commission states. The analysis suggested that effective commissions avoid having members represent geographical regions and political parties and avoid giving the commission the power to select the director of the DOT. In addition the states …

Synthesizing E-Government Stage Models – A Meta-Synthesis Based On Meta-Ethnography Approach, Keng Siau, Y. Long

Research Collection School Of Computing and Information Systems

The growing interest in e-government raises the question of stages in e-government development. A few stage models for e-government have been proposed. Without a common e-government stage model, different research in e-government may be based on different stage models. This presents a difficulty in comparing and understanding different research results. In this research, we synthesize the existing e-government stage models so that there is a common frame of reference for researchers and practitioners in the area.
