Content Differences Between Print And Online Newspapers, Jessica E. Smith

USF Tampa Graduate Theses and Dissertations

The Internet provides the opportunity to develop a new way to present journalism, but many scholars say newspaper Web sites do nothing but mirror their print parents. This study used content analysis to compare the content of stories in five newspapers with their Web counterparts, and it examines whether reporter affiliation or a story's geographic emphasis has a relationship with the story's amount of contextual elements. These elements could include photos, graphics, or multimedia or interactive components online. This approach applied gatekeeping theory to publications that have editions in two media.

This study examined the five largest newspapers in the …

Long Term Behavior Of The Positive Solutions Of The Non-Autonomous Difference Equation X N+1= A N X N-1 [Divided By] 1+Xn , N = 0,1,2,...., Mark Bellavia

Theses

It is our goal to investigate the long term behavior of the solutions of the following difference equation: X _n+1= A _n x _n-1 [divided by] 1+X_n , n = 0,1,2,...., Where {A_n}∞ _n=0 is a periodic sequence of positive real numbers. We will examine how the different periods of the sequence and the relationship of the terms of the sequence affect the long term behavior of the solutions.

Fuzzy Membership Function Initial Values: Comparing Initialization Methods That Expedite Convergence, Stephanie Scheibe Lee

Theses and Dissertations

Fuzzy attributes are used to quantify imprecise data that model real world objects. To effectively use fuzzy attributes, a fuzzy membership function must be defined to provide the boundaries for the fuzzy data. The initialization of these membership function values should allow the data to converge to a stable membership value in the shortest time possible. The paper compares three initialization methods, Random, Midpoint and Random Proportional, to determine which method optimizes convergence. The comparison experiments suggest the use of the Random Proportional method.

A Topological Approach To Nonlinear Analysis, Wendy Ann Peske

Theses Digitization Project

A topological approach to nonlinear analysis allows for strikingly beautiful proofs and simplified calculations. This topological approach employs many of the ideas of continuous topology, including convergence, compactness, metrization, complete metric spaces, uniform spaces and function spaces. This thesis illustrates using the topological approach in proving the Cauchy-Peano Existence theorem. The topological proof utilizes the ideas of complete metric spaces, Ascoli-Arzela theorem, topological properties in Euclidean n-space and normed linear spaces, and the extension of Brouwer's fixed point theorem to Schauder's fixed point theorem, and Picard's theorem.
