Elementary Teachers’ Mental Models Of Engineering Design Processes: A Comparison Of Two Communities Of Practice, Ann Piening Mcmahon

Dissertations

Educating K-12 students in the processes of design engineering is gaining popularity in public schools. Several states have adopted standards for engineering design despite the fact that no common agreement exists on what should be included in the K-12 engineering design process. Furthermore, little pre-service and in-service professional development exists that will prepare teachers to teach a design process that is fundamentally different from the science teaching process found in typical public schools. This study provides a glimpse into what teachers think happens in engineering design compared to articulated best practices in engineering design.

Wenger’s communities of practice work and …

The Picture Exchange Communication System: Digital Photographs Versus Picture Symbols, Carmen Jonaitis

Dissertations

The Picture Exchange Communication System (PECS) is an augmentative and alternative system (AAC) used to improve and increase communication for children with Autism Spectrum Disorder (ASD) and other developmental disorders. Research addressing the efficacy of this system is increasing; however, there is limited information published that evaluates the picture type used for PECS instruction. A single-subject alternating treatments design was used to examine the role of iconicity, or how closely a symbol resembles its referent, in the acquisition of picture discrimination in the third phase of PECS. The purpose of this study was to compare how well children were able …

Death By Boredom: The Role Of Visual Processing Theory In Written Evaluation Communication, Stephanie D. H. Evergreen

Dissertations

Evaluation reporting is an educational act and, as such, should be communicated using principles that support cognition. This study drew upon visual processing theory and theory-based graphic design principles to develop the Evaluation Report Layout Checklist intended to guide report development and support cognition in the readers of evaluation reports. It was then reviewed by an expert panel and applied by a group of raters to a set of evaluation reports obtained from the Informal Science Education evaluation website with maximum variability sampling. Results showed fairly high exact percent agreement and strong to very strong correlation with the author’s ratings. …

Shock Rhetoric, David Robert Nelson

Dissertations

Social movements create a public perception of themselves through rhetorical messages and demonstrations. In order to gain the public's attention, some radical groups use any rhetorical means necessary, including offensive remarks and conduct. Groups, such as the Westboro Baptist Church and Bash Back!, rhetorically challenge the boundaries of prudence. The purpose of this study is to identify, depict, and provide insight regarding shock rhetoric. This study will compare protest methods, visual imagery, and language choices used by Bash Back! and the Westboro Baptist Church. This dissertation helps illuminate why and how groups or individuals use shock rhetoric.

Dissertations

This dissertation focused on the challenges Mississippi weekly newspaper editors faced when deciding to have an online edition and the issues these editors encountered when they adopted a Web newspaper. The study expounded on four areas—the operational changes weekly newspapers have had to make to produce Web editions, the different type of newsroom staff that are needed to create both editions, the content that is going in the online edition, and the financial pressures that editors work through to keep the newspapers profitable. The study was modeled after similar studies from three organizations—the Pew Research Center, the Bivings Group, and …

Reading With A Critical Global Perspective: A Study Of Children's & Adolescent's Literature On South Asia, 1989-2009., Manika Subi Lakshmanan

Dissertations

This study examines how children’s and adolescent’s literature promotes global awareness, cross-cultural understanding and cosmopolitanism. It proposes an alternative critical global perspective in the teaching of complex narratives dealing with socio-economic and political transformations in the developing world, with specific reference to South Asian societies. Reframing how transcultural literature is read, a critical global perspective combines global perspectives distilled from theories of development, human rights and international relations, Michel Foucault’s notion of discourse and critical analysis, and textual and visual analysis (Stephens, 1992; Kress and van Leeuwen, 1996). This multidimensional approach contributed 20 questions that explored the gap between cultural …

In The Margins: Thresholds Of Text And Identity In U.S.-Mexico Border Literature, Allison E. Fagan

Dissertations

My project links discussions of U.S.-Mexico border literature's emphasis on marginalized identity with the growing textual studies interest in the marginal, often-invisible processes which aid the production and shape the reception of books. The dissertation not only calls attention to textual instability, or the places where the differing and even opposing intentions of authors, publishers, and editors often become strikingly clear, but also focuses on the political, racial, ethnic, and social instabilities inherent in publishing the work of borderlands writers. It advocates and advances a sustained attentiveness to the conditions under which border literature can and does get produced. Authors …

What Is The Optimal Structure For Organisations Representing Design And Designers On The Island Of Ireland?, Barry Sheehan

Dissertations

The research question addresses the issue of the structure of organisations that represent the interests of design and designers on the island of Ireland. The role of designers in Ireland is seen by society as marginal, rather than one central to the economic, social, and cultural well being of the island and those who live on it. This problem is exacerbated, as the organisational structures of those who play a key part are both confused and confusing. The answer to the question of what is an optimal structure lies in the literature that has been written on the subject and …

Computing For Knowledge Management: From Nonaka To Visualisation And Knowledge Maps, Helmut Huber

Dissertations

Management itself is not always clearly understood, however, the confusion can be sorted if the underlying theory is clearly distinguished from its implementations. There also may be a specific role for computing in Knowledge Management. It is suggested that Knowledge Management technologists seek a unique strategic position for Computing in Knowledge Management, for reasons of clarity and differentiation from Information Systems. The effective transfer of knowledge is one of the main themes or core competency in Knowledge Management. This is also one of the areas where Knowledge Management technologists may find the niche for a distinct and unique contribution the …

An Experimental Study Of Instructor Immediacy In The Wimba Virtual Classroom, Lorah Wood Bodie Edd

Dissertations

The social underpinnings of learning make it important to understand how people experience themselves and form relationships in web-based educational environments. Social presence is a critical factor of a communication medium that plays an important role in building community and improving the effectiveness of instruction. The components of social presence include words conveyed, verbal and nonverbal immediacy cues, and the context of the communication. The immediacy component of social presence is most often defined as perceived psychological closeness which is created in part by nonverbal cues (e.g., smiling and using gestures) and verbal cues (e.g., utilizing humor and inclusive pronouns). …

“Imagined Communities” In Showcases: The Nationality Rooms Program At The University Of Pittsburgh (1926-1945), Lucia Curta

Dissertations

From the inception of the program in 1926, the Nationality Rooms at the University of Pittsburgh were viewed as apolitical in their iconography. Their purpose was primarily didactic. Designed as classrooms meant for lectures and seminars, they were however ad-hoc museums for the display of symbols of national identity. In many ways, they constitute an excellent illustration in terms of the decorative arts of Benedict Anderson's concept of "imagined communities."

The identity referent of the symbolism attached to the decorative arrangements of these rooms was not that of the ethnic communities in Pittsburgh, for whom the rooms were supposedly designed …

Virtual Teams Combining Mobile Devices With Web-Based Communication On Group Decision Making, Hyo-Joo Han

Dissertations

Organizations have moved from a face-to-face team environment to a virtual team environment using communication technology during the last decade. More and more workers use asynchronous tools (including email, discussion groups, information sharing tools, and group calendaring systems), and synchronous tools, such as instant messaging and web-based chatting features, to coordinate and share information with people within and outside of organizations. This empirical study on how virtual teams work, integrating mobile devices with web-based group communication for decision-making tasks, examines which technologies and communication modes are the best for distributed group teamwork, and, mainly, what are the predictive characteristics making …

Robust And Efficient Video/Image Transmission, Xi Min Zhang

Dissertations

The Internet has become a primary medium for information transmission. The unreliability of channel conditions, limited channel bandwidth and explosive growth of information transmission requests, however, hinder its further development. Hence, research on robust and efficient delivery of video/image content is demanding nowadays.

Three aspects of this task, error burst correction, efficient rate allocation and random error protection are investigated in this dissertation. A novel technique, called successive packing, is proposed for combating multi-dimensional (M-D) bursts of errors. A new concept of basis interleaving array is introduced. By combining different basis arrays, effective M-D interleaving can be realized. It has …

Motion Compensation And Very Low Bit Rate Video Coding, Shu Lin

Dissertations

Recently, many activities of the International Telecommunication Union (ITU) and the International Standard Organization (ISO) are leading to define new standards for very low bit-rate video coding, such as H.263 and MPEG-4 after successful applications of the international standards H.261 and MPEG-1/2 for video coding above 64kbps. However, at very low bit-rate the classic block matching based DCT video coding scheme suffers seriously from blocking artifacts which degrade the quality of reconstructed video frames considerably. To solve this problem, a new technique in which motion compensation is based on dense motion field is presented in this dissertation.

Four efficient new …

On Optimal Design And Applications Of Linear Transforms, Mehmet V. Tazebay

Dissertations

Linear transforms are encountered in many fields of applied science and engineering. In the past, conventional block transforms provided acceptable answers to different practical problems. But now, under increasing competitive pressures, with the growing reservoir of theory and a corresponding development of computing facilities, a real demand has been created for methods that systematically improve performance. As a result the past two decades have seen the explosive growth of a class of linear transform theory known as multiresolution signal decomposition. The goal of this work is to design and apply these advanced signal processing techniques to several different problems.

The …

Theory, Design And Applications Of Linear Transforms For Information Transmission, Adil Benyassine

Dissertations

The aim of this dissertation is to study the common features of block transforms, subband filter banks, and wavelets, and demonstrate how discrete uncertainty can be applied to evaluate these different decomposition techniques. In particular, we derive an uncertainty bound for discrete-time functions. It is shown that this bound is the same as that for continuous-time functions, if the discrete-time functions have a certain degree of regularity.

This dissertation also deals with spectral modeling in filter banks. It is shown, both theoretically and experimentally, that subspectral modeling is superior to full spectrum modeling if performed before the rate change. The …

A Generalized, Parametric Pr-Qmf/Wavelet Transform Design Approach For Multiresolution Signal Decomposition, Hakan Caglar

Dissertations

This dissertation aims to emphasize the interrelations and the linkages of the theories of discrete-time filter banks and wavelet transforms. It is shown that the Binomial-QMF banks are identical to the interscale coefficients or filters of the compactly supported orthonormal wavelet transform bases proposed by Daubechies.

A generalized, parametric, smooth 2-band PR-QMF design approach based on Bernstein polynomial approximation is developed. It is found that the most regular compact support orthonormal wavelet filters, coiflet filters are only the special cases of the proposed filter bank design technique.

A new objective performance measure called Non-aliasing Energy Ratio(NER) is developed. Its merits …
