Discreet Dynamical Population Models : Higher Dimensional Pioneer-Climax Models, Yogesh Joshi

Dissertations

There are many population models in the literature for both continuous and discrete systems. This investigation begins with a general discrete model that subsumes almost all of the discrete population models currently in use. Some results related to the existence of fixed points are proved. Before launching into a mathematical analysis of the primary discrete dynamical model investigated in this dissertation, the basic elements of the model - pioneer and climax species - are described and discussed from an ecological as well as a dynamical systems perspective. An attempt is made to explain why the chosen hierarchical form of the …

Road-Based Routing In Vehicular Ad Hoc Networks, Josiane Nzouonta-Domgang

Dissertations

Vehicular ad hoc networks (VANETs) can provide scalable and cost-effective solutions for applications such as traffic safety, dynamic route planning, and context-aware advertisement using short-range wireless communication. To function properly, these applications require efficient routing protocols. However, existing mobile ad hoc network routing and forwarding approaches have limited performance in VANETs. This dissertation shows that routing protocols which account for VANET-specific characteristics in their designs, such as high density and constrained mobility, can provide good performance for a large spectrum of applications.

This work proposes a novel class of routing protocols as well as three forwarding optimizations for VANETs. The …

Optimizing Replenishment Order Quantities In Uncoordinated Supply Chains, Atipol Kanchanapiboon

Dissertations

Many modern supply chains can be described as a series of uncoordinated suppliers. That is each supplier establishes their individual inventory and production policies on both the input and output sides. In these supply links there is minimal coordination between suppliers, and typically only prices and delivery guarantees are contracted. As a consequence, the inventory behavior and associated costs do not exhibit standard patterns. This makes it difficult to model and optimize these chains using classical inventory models. The common approach, therefore, for evaluating uncoordinated supply chains is to use Supply Chain Analytics software. These retrieve operational data from Enterprise …

Numerical Detection Of Complex Singularities In Two And Three Dimensions, Kamyar Malakuti

Dissertations

Singularities often occur in solutions to partial differential equations; important examples include the formation of shock fronts in hyperbolic equations and self-focusing type blow up in nonlinear parabolic equations. Information about formation and structure of singularities can have significant role in interfacial fluid dynamics such as Kelvin-Helmholtz instability, Rayleigh-Taylor instability, and Hele-Shaw flow. In this thesis, we present a new method for the numerical analysis of complex singularities in solutions to partial differential equations. In the method, we analyze the decay of Fourier coefficients using a numerical form fit to ascertain the nature of singularities in two and three-dimensional functions. …

Enterprise Information Technology Organizational Flexibility : Managing Uncertainty And Change, Karen Prast Patten

Dissertations

Chief Information Officers (CIOs) lead enterprise information technology organizations (EITOs) in today's dynamic competitive business environment. CIOs deal with external and internal environmental changes, changing internal customer needs, and rapidly changing technology. New models for the organization include flexibility and suggest that CIOs should create and manage an enterprise IT organization that is more flexible in order to manage change and prepare for uncertainty, but they do not define what is meant by flexibility.

The first objective of this exploratory and ethnographic research study was to understand how uncertainty and unexpected change are currently managed by CIOs. The second was …

Leadership In Partially Distributed Teams, Linda Plotnick

Dissertations

Inter-organizational collaboration is becoming more common. When organizations collaborate they often do so in partially distributed teams (PDTs). A PDT is a hybrid team that has at least one collocated subteam and at least two subteams that are geographically distributed and communicate primarily through electronic media. While PDTs share many characteristics with both traditionally collocated and fully distributed teams, they also have unique characteristics and issues.

This dissertation reports on a field study of PDTs conducted over two semesters with student participants, This research was conducted as part of a larger series of studies investigating PDTs, In these studies, participants …

Children's Story: Per-Se-Vere, Virginia De La Garza

Critical and Creative Thinking Capstones Collection

We constantly come across problems or challenges that have no predetermined answer or solution. Perseverance is a very important disposition that makes us persist in the search of something we have started. I believe that people who want to persevere not only need to be motivated but, more importantly, they need to understand what it takes to persevere or, in other words, know how to persevere. Developing strategies to face and overcome confusion, obstacles, and frustrations is needed for learning. The teaching of Intellectual Perseverance is frequently taken for granted or not taught appropriately. Attitudes, dispositions, and habits of mind …

Exploring The Teaching Mind: Extending Participation In Lifelong Learning Through Engagement With A Supportive Community, Jeremy Szteiter

Critical and Creative Thinking Capstones Collection

This paper extends the notion of lifelong learning beyond gaining knowledge over a lifetime to preparing oneself to teach what has been learned to others. The "Teaching Mind," as I define the idea, involves thinking about what has been learned and what one knows by reconsidering that knowledge through the eyes of self as a teacher. The Teaching Mind assumes a broad notion of teaching that relates to informal and community learning across all areas of life and culture, beyond professional teaching in formal schools. The pursuit of the Teaching Mind is highly accessible to all those who wish to …

The Influence Of Organizational And Information Systems Factors On The Effectiveness Of Post-Merger Technology Integration, Gianilda A. Morsell

Dissertations

This dissertation explores how ten specific organizational and information systems factors influence post-merger IS integration success, and the role that degree of IS integration plays in moderating the influence these factors may have on IS integration success. Data were gathered, using a self-administered survey instrument, from senior IS executives at firms that experienced a U.S. public merger greater than $25 million between 2004 and 2007. Support is found for the study's Conceptual Model, indicating that all ten factors in unison influence post-merger IS integration success. The data support the hypotheses that quality of merger planning, quality of communication of merger …

Clustered Wireless Sensor Networks, Renita Margaret Machado

Dissertations

The study of topology in randomly deployed wireless sensor networks (WSNs) is important in addressing the fundamental issue of stochastic coverage resulting from randomness in the deployment procedure and power management algorithms. This dissertation defines and studies clustered WSNs, WSNs whose topology due to the deployment procedure and the application requirements results in the phenomenon of clustering or clumping of nodes. The first part of this dissertation analyzes a range of topologies of clustered WSNs and their impact on the primary sensing objectives of coverage and connectivity. By exploiting the inherent advantages of clustered topologies of nodes, this dissertation presents …

The Constitution Of Equality: Democratic Authority And Its Limits By Thomas Christiano (Book Review), David Lefkowitz

Philosophy Faculty Publications

In this carefully argued and thought provoking new book, Thomas Christiano offers a novel defense of democracy's intrinsic value, its morally justifiable claim to authority, and the limits thereof, as well as for liberal rights. Central to Christiano's argument for each of these conclusions is the claim that in a moderately complex and pluralist society, social justice requires that people be treated publicly as equals. That is, ordinary agents must be able to see that the institutions and practices that provide the basic structure of the society in which they live treat them as equals, or what is the same, …
