The purpose of this study was to develop a model that would enhance the development, dissemination, and adoption of educational multimedia materials. The grounded theory definition of open coding was used to analyze data collected from the 3-year Technology Leadership Web Library Project at the University of North Texas. Weekly meeting minutes, email communication, reports, notes, questionnaires, and surveys were examined to determine major factors involved in the process of product development and dissemination. From the analysis of this study, five major factors in product development and dissemination were identified. These factors were leadership, team dynamics, expert advisors, feedback, and consumers. The synthesis of the factors led to the development of the PROMOTE (process revolving around ongoing management of team and evaluative feedback) model. The PROMOTE model is based on the establishment of a system that includes leadership, development team, and expert advisors at its center. The system is tied together with well-established feedback loops for stages of evaluation. The PROMOTE model is iterative and uses consumer feedback to generate new products. The PROMOTE model differs from other product development and evaluation models both in the focus of the process and the nature of the evaluation feedback.

abstract: In the fast-paced, technology-driven society of today, new demands are placed on artists to re-think how music is presented and communicated to the world. Access to the internet, development of sound manipulation software, and broader means of use and distribution through the digital music industry have drastically shifted the way the twenty-first century artist creates and performs music. One of the most striking changes that occurred is the increased use of visual material as a vehicle to enhance and contribute to the depth and intrigue of live performances and recordings. This project researches twenty-first century works for clarinet and multimedia that specifically include a visual element (including but not limited to images, fixed and interactive video, light effects, and choreography) and highlights the prevalence of this genre in contemporary repertoire. Discussion begins with a brief overview of the history of multimedia, its relation to the clarinet, and how it has been defined by the twenty-first century. Additionally, in order to contribute to this ever-growing repertoire, three new works for clarinet and multimedia were commissioned in collaboration with composers and visual artists. These new works include: Roadrunner (2019) for clarinet and fixed electronics by Spencer Brand with video by Samuel Proctor; I’d known this place (2020) for clarinet and electronics by Dan Caputo with live audio generative animations by Andrew Robinson; and Spectral Passages (2020) for clarinet and electronics by Alvaro Varas with painting by Miguel Godoy. Background information and performance guides are included for each piece to aid future musicians in performance, as well as respective audio/video recordings. Finally, a significant portion of this document includes a catalog of works for clarinet and multimedia. The catalog was compiled by focusing on the output of twenty-first century composers to serve as a resource for future performers. / Dissertation/Thesis / Roadrunner for clarinet and electronics by Spencer Brand / Spectral Passages for clarinet and electronics by Alvaro Varas / I'd known this place for clarinet and electronics by Dan Caputo / Doctoral Dissertation Music 2020

Musica Speculativa is a final project in two parts in which I explore, through both theory and practice, the role of metaphors in our understanding of reality with special attention given to the use of visual representation in multimedia concert works that employ electroacoustics. Part I, entitled, "Imaginary Cognition: Interpreting the Topoi of Intermedia Electroacoustic Concert Works," explores how metaphors play a core role in our musical experience and how aural metaphors can be enhanced by and ultimately interact with visual metaphors to create a contrapuntal intermedia experience. Part II, "Musica Speculativa: A Multimedia Concert in Five Movements and Three Intermezzi," for mezzo-soprano, flute, B-flat bass clarinet, violin, cello, piano, a percussionist performing an array of lightning bottles, a dancer with a gesture-sensing wand, and a technologist operating interactive audio and video processing, focuses on the medieval philosophy of Musica Speculativa and how it relates to our current understanding of the world. In part I explore the heightened experience of metaphorical exchange through the utilization of multimedia. The starting point is the expansion of visual enhancement in electroacoustic compositions due to the widespread availability of projection in concert halls and the multimedia expectations created through 21st-century Western culture. With the use of visual representation comes the potential to map musical ideas onto visual signs, creating another level of cognition. The subsequent unfolding of visual signifiers offers a direct visual complement and subsequent interaction to the unfolding of aural themes in electroacoustic compositions. The paper surveys the current research surrounding metaphorical thematic recognition in electroacoustic works whose transformational processes might be unfamiliar, and which in turn create fertile ground for the negotiation of meaning. The interaction of media and the differences created among the various signs within the music and the visual art create a heightened concert experience that is familiar to and in many ways expected by contemporary listeners. Composers such as Jaroslaw Kapuscinski have sought to use multimedia as a means to enhance the concert experience, giving movement to the acousmatic presence in their electroacoustic works. In turn, these works create a concert experience that is more familiar to the 21st-century audience. Through examining Kapuscinski's recent work, Oli's Dream, in light of cognitive research by Zbikowski (1998 & 2002), topic theory by Agawu (1991 & 2009), and multimedia research by Cook (1998), I propose a theory for analyzing contrapuntal meaning in multimedia concert works. The themes explored in Part I, regarding the use of metaphor to interpret both visual and aural stimuli, ultimately creating a metaphor for a reality never fully grasped due to the limits of human understanding, are further explored artistically in the multimedia concert work, Musica Speculativa. The medieval philosophy of Musica Speculativa suggests that music as it is understood today (musica instrumentalis) is the only tangible form of the metaphysical music ruling human interactions (musica humana) and ordering the cosmos (musica mundana). I found the concept of Musica Speculativa to be a fitting metaphor for how music and art allude to our own perception of reality and our place within that world. The project as a whole re-examines the concept of Musica Speculativa in light of our current technological landscape to gain a deeper understanding of how we interact with the world around us. / Music Composition / Accompanied by one .pdf score: Musica Speculativa.

Dieser Artikel stellt ein Framework zur Generierung von Metadaten der technischen Randbedingungen eines Ingests vor, welches an der Professur Medieninformatik im Rahmen des Projektes ValidAX zur Digitalisierung verschiedener Videokassettenformate entwickelt wurde. Insbesondere werden hierbei die Architektur und der Einsatz näher beleuchtet. / The process of introducing media into an IT-based system during acquisition is called ingest. The appropriate handling of media requires the extraction of additional metadata being realized by automatic extraction and analysis as well as manual annotation. We assume, that metadata about technical constraints of the ingest process itself implies a benefit for the media lifecycle. In this context the challenge is the automation.

Wireless multimedia sensor networks (WMSNs) are networks of interconnected devices that allow retrieving video and audio streams, still images, and scalar data from the environment. In a densely deployed WMSN, there exists correlation among the observations of camera sensors with overlapped coverage areas, which introduces substantial data redundancy in the network. In this dissertation, efficient communication schemes are designed for WMSNs by leveraging the correlation of visual information observed by camera sensors. First, a spatial correlation model is developed to estimate the correlation of visual information and the joint entropy of multiple correlated camera sensors. The compression performance of correlated visual information is then studied. An entropy-based divergence measure is proposed to predict the compression efficiency of performing joint coding on the images from correlated cameras. Based on the predicted compression efficiency, a clustered coding technique is proposed that maximizes the overall compression gain of the visual information gathered in WMSNs. The correlation of visual information is then utilized to design a network scheduling scheme to maximize the lifetime of WMSNs. Furthermore, as many WMSN applications require QoS support, a correlation-aware QoS routing algorithm is introduced that can efficiently deliver visual information under QoS constraints. Evaluation results show that, by utilizing the correlation of visual information in the communication process, the energy efficiency and networking performance of WMSNs could be improved significantly.

This report begins with the presentation of "the state of the art" as well as the foreseen trend in the education system in Mozambique and analyses the present situation in the area utilizing media opportunities for teaching and/or learning. Basing on this analysis, the prevailing problems and the aims (this might need research) of the study shall then be identified and formulated (chapter 1 and 2). The necessity to carry out the study is grounded by the worldwide stormy developments utilizing modern information technology. These developments do also apply to Mozambique as the pre-studies show. A flashback on the history of teaching-/learning system as well as on present solutions utilizing new media and new information as well as communication technology shall be discussed in the third chapter. To this end, the study shall contribute to identify the lacking of previous concepts as well as to introduce an orientation as to the current world sustainable system. The software for training on the market at present show (without doubt) that they reflect developers' imaginations (knowingly or unknowingly) as to what learning and teaching actually is and how this process take place. Basing on this knowledge, it is worth to work out the starting point as to teaching-/learning methodology before working out a conception. In addition, it shall be made clear (in the course of analysis) that the dominating criterion for customizing a teaching-/learning system is that system or its form that has been realised. The contribution of this report, further, is to make the definition of the media more precise by adding new terminology that shall be discussed and viewed from different viewpoints. This shall in turn contribute to a clear and sound understanding of the media. In the past years, a series of different teaching and methodologies concepts on the design of computer-based teaching-/learning environment were developed and discussed. Among them is the so called "anchored instruction" of the cognition and Technology Group based at Vanderbilt University and the Cognitive Apprenticeship developed by Collins, Brown and their co-workers. This shall be dealt with in the fourth chapter. On that basis, and taking other factors into consideration, such as design, functionality, applications scenarios, boundary conditions as well as user backgrounds, a more effective teaching-/learning environment can be predicted and consequently a concrete design proposal can be derived. The guidelines strived as to the design of context-sensitive multimedia teaching and learning environment shall not only be treated intuitive, but implemented technically in a prototype. In so doing they can then be evaluated and adopted. The so evaluated guidelines and other relevant design proposals that can find use in other areas with respect to the demand of the study as a whole shall make the results of this report. The fifth chapter shall describe the development and evaluation of prototype-art "e-Aula" solutions basing on the developed and grounded conception. The conception constitutes of a hybrid solution in the form of training software that supports both freelance as well as classroom learning. This training technology solution is called teaching-/learning environment and it is being characterised through its feature that it embodies two system interfaces having functions (learning environment and teaching arrangement) that basically refer to the same data collection (media) that can be accessed by the in different ways. This function rates "e-Aula" at a relatively higher position in comparison with a number of learning systems. The sixth chapter shall then summarise the important findings of the report and recommend areas for further research.
