Playing The Game: Female Graduate Students’ Communication Experiences, Jacqueline Marie Brucher

Dissertations and Theses @ UNI

In this thesis I examine the communication experiences of four female graduate students and the language they use to describe those experiences. Specifically, the women's use of metaphor to describe their academic environments is explored. A qualitative analysis of the linguistic choices of these women is achieved by applying Kenneth Burke's cluster analysis. I attempt to break the boundaries of rhetorical criticism by applying cluster analysis to conversation. Not only does this application open up new uses for the methodology, it also introduces additional means of analyzing various types of communication. All four women describe graduate school as "a game." …

Low-Cost Videoconferencing For The Clinical Management Of Speech & Language Disorders, Dale Lee Burgess

Dissertations and Theses @ UNI

Videoconferencing allows participants separated by distance to see and hear each other in real time. Traditionally, videoconferencing has been associated with expensive, room-based systems that limit the number of potential users. Recent advances in technology have made it possible to videoconference via desktop computers using inexpensive software programs. This has allowed broader participation in videoconferencing, thus, making it a more affordable means of communication. The purpose of this study was to determine if desktop videoconferencing (DVC) could be used in the clinical management of individuals with communication disorders. One of the potential advantages of DVC over traditional therapy programs is …

Typographic Communication, Soo-Kyung Chun

Dissertations and Theses @ UNI

The main influence on my graduate work has been the art of my native country of South Korea. A predominant feature of oriental paintings is black ink. I have always been intrigued by the balance of black and white elements which I associate with figure- and- ground in Western design theory. This intrigue has continued as my education has broadened into the field of graphic design. The opportunity to combine artistic intuition with technical computer- based media prompted me to study graphic design at the University of Northern Iowa beginning in 1996.

Piezoelectric Biomechanical Assessment Of Swallowing Across Ages And Swallowing Task, Janel Elizabeth Crow

Dissertations and Theses @ UNI

Even though the Modified Barium Swallow (l\1BS) is the gold standard for the evaluation of swallowing disorders, the MBS has several limitations ( e.g., invasiveness, cost and portability). Noninvasive tools to measure swallowing ability at low cost and with low risk to the patient are desirable. Recently, thin film, piezoelectric technology (Computerized Laryngeal Analyzer: CLA) has become available which allows for noninvasive biomechanical analysis of swallowing. Noninvasive biomechanical measurement of swallowing is possible due to the close correlation of hyolaryngeal movement, airway protection and upper esophageal sphincter (UES) opening (Jacob, Kahrilas, Logemann, Shah, & Ha, 1989). The vertical and anterior …

Evaluating Information Modeling Methods – A Review, Keng Siau, M. Rossi

Research Collection School Of Computing and Information Systems

Hundreds of modeling methods are in existence today, yet practitioners and researchers are zealously “producing” new modeling methods. The “blooming” of modeling methods is not the problem; the lack of standardized techniques for evaluating them is. To further complicate the matter, most of the modeling methods are introduced based on common sense and intuition. Theoretical foundations and empirical evidence are severely lacking. With the current state of affairs, evaluation of modeling methods has become necessary. Comparing modeling methods provides us with the necessary knowledge and understanding on the strengths and weaknesses of each method. This knowledge can also guide us …

Gangs, Drugs, And Delinquency, Tina Renea Engstrom

Dissertations and Theses @ UNI

The main objective of this thesis is to study the link between gangs, drug use, and delinquency. Previous literature suggests that social learning and social control theories commonly provide theoretical contexts for explaining deviant behavior. The present research applies the principles of Sutherland's (1949) theory of differential association and Hirschi' s (1969) theory of social control to the delinquent behavior of gang members and their drug involvement. The present study does not attempt to explain why youths become gang members. Rather, this research uses an integration of social learning and social control theories to explain why gang members become involved …

A Transaction Model For Mobile Computing, Sanjay Kumar Madria, Bharat Bhargava

Computer Science Faculty Research & Creative Works

We introduce a prewrite operation before a write operation in a mobile transaction to improve data availability. A prewrite operation does not update the state of a data object but only makes visible the value that the data object will have after the commit of the transaction. Once the transaction has read all the values and declares all the prewrites, it can precommit at a mobile host. The remaining transaction's execution is shifted to the stationary host. Writes on a database consume both time and resources at the stationary host and are therefore delayed. A pre-committed transaction's prewrite values are …

Optical Digital Fragmentation Measuring Systems -- Inherent Sources Of Error, Norbert H. Maerz, Wei Zhou

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Automated optical imaging systems of measuring fragmentation are increasingly being used in the mining, comminution, and materials handling industries. These methods have been well received in many of the industries involved. Considering that in many of these applications there are no alternative ways of sizing material, having even a rudimentary measurement of size distributions allows evaluations of explosive, blast design, detonator performance, crusher and milling performance, and material degradation due to transport.

Optical methods have inherent limitations, which reflect on accuracy, precision, and reproducibility of measurement results. This stems from the fact that there are myriads of variables, which affect …

It's Not What You Make, It's The Way That You Say It: Reflections On The Design-Marketing Interface, Paul O'Sullivan

Articles

Good design is a cornerstone of marketing. Design is an important variable in every aspect of marketing activities- products, processes, packaging and communications. Yet this topic attracts little attention in the marketing literature and there is, one suspects, very little cross-fertilisation between marketing and design disciplines. This paper puts design on the agenda for both marketing academics and practitioners as well as providing a review of what is embraced within the broad subject of design. Some observations on the history and role of design in an Irish context are offered also.

The Changing Nature Of Theory And Practice In Marketing: On The Value Of Synchrony, Aidan O'Driscoll, John Murray
