Show moreThe motivation behind this research is the prevalence of challenges and ambiguity associated with successful organizational change and the numerous available approaches in dealing with these challenges and ambiguity.Many definitions and methods have been suggested to manage change; however, organizations still report a high failure rate of their change initiatives. These high failure rates highlight the continuing need for research and investigation, and imply a lack of a valid framework for managing successful organizational change. This dissertation critically reviews the concept of having one change approach as the (")silver-bullet("). In pursuit of this goal, this research contributes a roadmap to the change management literature and provides definitions for describing change types, change methods and change outcomes. This dissertation also develops a conceptual model that proposes relationships and connections between the change types, change method and change outcomes that is assumed to enable successful change. To validate the research conceptual model, two hypotheses were developed and a self-administered survey was created and administered (paper survey and online). The respondents were professionals involved in change projects in the Central Florida region. The unit of analysis in this research was a completed change project. Respondents were asked to complete the survey for two different projects: a successful project and an unsuccessful project. Statistical processes were applied to verify the conceptual model and test the research hypotheses.Based on the data collected, exploratory factor analysis was used to verify the validity and reliability of the conceptual model measures. Results of the hypotheses testing revealed that there are relationships between the complexity of the change type and the use of change methods that significantly relate to successful change. The results also revealed that the alignment of the change type and change methods significantly relates to successful change.From the viewpoint of change project managers, the results of this dissertation have confirmed that the complexity of the change project type negatively correlates with change success and the increased use of change methods positively correlates with change success. The results also confirmed that the methods that highly correlate to change success address the following: (a) the situation that needs changing, (b) the proper implementation of change, (c) the establishment of suitable plans and controls to sustain change, and (d) the presence of a credible team leader who influences the major decisions during the change project.

Hong, Yan, Su, Ming, University of Central Florida
Abstract / Description
A major challenge of developing faster and smaller microelectronic devices is that high flux of heat needs to be removed efficiently to prevent overheating of devices. The conventional way of heat removal using liquid reaches a limit due to low thermal conductivity and limited heat capacity of fluids. Adding solid nanoparticles into fluids has been proposed as a way to enhance thermal conductivity of fluids, but recent results show inconclusive anomalous enhancements in thermal conductivity....
Show moreA major challenge of developing faster and smaller microelectronic devices is that high flux of heat needs to be removed efficiently to prevent overheating of devices. The conventional way of heat removal using liquid reaches a limit due to low thermal conductivity and limited heat capacity of fluids. Adding solid nanoparticles into fluids has been proposed as a way to enhance thermal conductivity of fluids, but recent results show inconclusive anomalous enhancements in thermal conductivity. A possible way to improve heat transfer is to increase the heat capacity of liquid by adding phase change nanoparticles with large latent heat of fusion into the liquid. Such nanoparticles absorb heat during solid to liquid phase change. However, the colloidal suspension of bare phase change nanoparticles has limited use due to aggregation of molten nanoparticles, irreversible sticking on fluid channels, and dielectric property loss. This dissertation describes a new method to enhance the heat transfer property of a liquid by adding encapsulated phase change nanoparticles (nano-PCMs), which will absorb thermal energy during solid-liquid phase change and release heat during freeze. Specifically, silica encapsulated indium nanoparticles, and polymer encapsulated paraffin (wax) nanoparticles have been prepared using colloidal method, and dispersed into poly-±-olefin (PAO) and water for high temperature and low temperature applications, respectively. The shell, with a higher melting point than the core, can prevent leakage or agglomeration of molten cores, and preserve the dielectric properties of the base fluids. Compared to single phase fluids, heat transfer of nanoparticle-containing fluids have been significantly enhanced due to enhanced heat capacities. The structural integrity of encapsulation allows repeated uses of nanoparticles for many cycles. By forming porous semi crystalline silica shells obtained from water glass, supercooling has been greatly reduced due to low energy barrier of heterogeneous nucleation. Encapsulated phase change nanoparticles have also been added into exothermic reaction systems such as catalytic and polymerization reactions to effectively quench local hot spots, prevent thermal runaway, and change product distribution. Specifically, silica-encapsulated indium nanoparticles, and silica encapsulated paraffin (wax) nanoparticles have been used to absorb heat released in catalytic reaction, and to mitigate the gel effect during polymerization, respectively. The reaction rates do not raise significantly owing to thermal buffering using phase change nanoparticles at initial stage of thermal runaway. The effect of thermal buffering depends on latent heats of fusion of nanoparticles, and heat releasing kinetics of catalytic reactions and polymerizations. Micro/nanoparticles of phase change materials will open a new dimension for thermal management of exothermic reactions.

Show moreSuccessful 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 in the digital era has become critical and it is treated as a major competitive tool for success. Complex and comprehensive IT infrastructures support the firm's communications network, databases, and operating systems. Information technology facilitates the creation of value. However, the creation of value is defined by the different groups of stakeholders. Therefore, stakeholders must be integrated into this process of change management that uses IT as the enabler. Supply chains are due to change when higher levels of performance and/or adaptation are required as mandated by changes in the business structure and/or benchmarking and/or regulations. One of the major problems for any supply chain executive is to understand and manage these changes. These changes usually require the implementation of an IT project. Therefore, the successful design, execution, and completion of these IT projects are important for the supply chain. SCM is now a strategic function addressed at the highest levels of the organization in concert with multiple stakeholders on both the supplier and customer side of the table. The aim of this dissertation is to develop a value mapping framework involving stakeholders to improve supply chain performance when implementing IT projects. The framework has components that help define the supply chain, measure the size of the issues, identify necessary changes in the metrics to improve performance, measure the organizational consequences of these changes, and develop and follow a plan to implement IT projects to achieve the new goals of performance. Through this new framework, these IT projects will be able to bring the supply chain from a current state "As is" to a future state "To be"; capturing the existing and desired states of the proposed changes which are aligned with the objectives and goals of the organization. Therefore, the IT project can be designed, executed, and completed. One unique component of this framework is the inclusion of the stakeholders at different stages. This framework identifies the group of stakeholders to be taken into consideration in order to define the future "To be" state. In addition, the framework identifies the value creation of the "To be" system as seen by the stakeholders.

Show moreFor all business organizations, there comes a time when a change must take place within their eco-system. It consumes a great deal of thought and planning to ensure that the right decision is made as it could alter the entire course of their business for a number of years to come. This change may appear in the form of a brilliant CEO reaching the age of retirement, or an unsuccessful Managing Director being asked to leave before fulfilling the term of her contract. Regardless of the cause, a transition must occur in which a suitable successor is chosen and put into place while minimizing costs, satisfying stakeholders, ensuring that the successor has been adequately prepared for their new position, and minimizing work place gossip, among other things. It is also important to understand how the nature of the business, as well as its financial standing, effects such a transition.Engineering and management principles come together in this study to ensure that organizations going through such a change are on the right course. As the problem of transitional management is not one of concrete values and contains many ambiguous concepts, one way to tackle the problem is by utilizing various industrial engineering methodologies that allow these companies to systematically begin preparing for such a change. By default, organizational strategy has to change, technology is continually being renewed and it becomes very hard for the same leader to constantly implement new and innovative developments.Organizations today have a very poor understanding of where they currently stand and as a result the cause for a company's lack of profitability is often overlooked with time and money being wasted in an attempt to fix something that is not broken. To be able to look at the bigger picture of an organization and from there begin to close in on the main problems causing a negative impact, the Matrix of Change is used and takes in many factors to layout an accurate representation of the direction in which an organization should be headed and how it can continue to grow and remain successful. The Theory of Constraints on the other hand is used here as a step-by-step guide allowing companies to be better organized during times of change. And System Dynamics modeling is where these companies can begin to simulate and solve the dilemma of transitional management using causal loop diagrams and stock and flow diagrams.Through such tools a framework can begin to be developed, one that is valued by corporations and continually reviewed. Several case studies, simulation modeling, and a panel of experts were used in order to demonstrate and validate this framework.

Show moreThe present study identifies the dimensions and variables using prior research within each of the constructs under the management systems, fit and, organizational strategy, structure, lifecycle and performance. The constructs from the research model were defined with a combination of direct, calculated and coded measures. Context analysis for each case categorized management systems design into either prescriptive or descriptive. The selected performance measures have been extensively investigated in the research fields associated with organizational management. The study uses the multiple case study design with cross-sectional data spanning from 1991 to 2005 and involving 19 aerospace companies in the United States. A priori hypothesized relationships between the constructs were tested with Mann-Whitney procedures for differences between mean ranks associated with organizational performance measures. The results from Mann-Whitney tests suggest that there exist significant differences in organizational performance from fit factors between a management system design and the organization. Present study defined organizational performance measures for analysis in terms of Return on Assets, Return on Equity and Return on Investment. When compared to a prescriptive management system design, a descriptive management system design was associated with higher levels of organizational performance. Cases with a fit state were found to score significantly higher than cases with unfit state suggesting that a correct fit state is associated with higher levels of organizational performance. A fit state was associated with higher levels of performance when each of the organizational factors for strategy, structure and lifecycle were aligned to management system design. Study results suggest equifinality as cases reached a particular fit state with differing combinations of fit factors. The study contributes to the field with interpretation of a fit model and key relationship between management systems and performance providing the base for future research efforts associated with management systems, organizational factors and the fit between them.

Show moreThis thesis discusses the specific effects of single sourcing methodologies on the role of the technical communicator, his or her job responsibilities, qualifications, collaboration with coworkers, employee and employer expectations, and the effects on career progression. The methodologies discussed included all types of single sourcing methods for technical documentation (such as XML-based), advanced and non-advanced Content Management Systems (CMS), and Digital Asset Management (DAM) systems. Other topics explored are an overview of single sourcing for technical documentation, a comparison of the "craftsman model" to the current trend of single sourcing and structured content, specific effects on technical communicators such as role changes, the effects of incorporating XML into a technical communicator's daily work environment, and the effects of other emerging technologies such as advanced CMS and DAM systems on technical communicators. General findings include that the practice of single sourcing, whether a positive or negative development, has continued and likely will continue to increase in technical communication groups within organizations. Single sourcing, especially for dynamic, customized content is also increasing because of the current marketplace, but works best via the use of a CMS and other systems used by large organizations. Single sourcing is also best implemented after extensive strategic planning and training of employees. Many technical communicators will have to accept new roles and positions, the direction of which is greatly impacted by the extent of their skills. Recommendations are made for additional research on the effects of single sourcing implementation on the technical communicator, and how to adapt to changes. Additional research is also needed on XML, DITA (Darwinian Information Typing Architecture), and DAM systems, all related specifically to technical communication.
