Quality criteria for multimedia
The meaning of the term quality as used by multimedia workers in the field has become devalued. Almost every package is promoted by its developers as being of the âhighest qualityâ. This paper draws on practical experience from a number of major projects to argue, from a qualityâassurance position, that multimedia materials should meet preâdefined criteria relating to their objectives, content and incidence of errors
Desktop multimedia environments to support collaborative distance learning
Desktop multimedia conferencing, when two or more persons can communicate among themselves via personal computers with the opportunity to see and hear one another as well as communicate via text messages while working with commonly available stored resources, appears to have important applications to the support of collaborative learning. In this paper we explore this potential in three ways: (a) through an analysis of particular learner needs when learning and working collaboratively with others outside of face-to-face situations; (b) through an analysis of different forms of conferencing environments, including desktop multimedia environments, relative to their effectiveness in terms of meeting learner needs for distributed collaboration; and (c) through reporting the results of a formative evaluation of a prototype desktop multimedia conferencing system developed especially for the support of collaborative learning. Via these analyses, suggestions are offered relating to the functionalities of desktop multimedia conferencing systems for the support of collaborative learning, reflecting new developments in both the technologies available for such systems and in our awareness of learner needs when working collaboratively with one other outside of face-to-face situations

CHORUS Deliverable 3.3: Vision Document - Intermediate version
The goal of the CHORUS vision document is to create a high level vision on audio-visual search engines in order to give guidance to the future R&D work in this area (in line with the mandate of CHORUS as a Coordination Action).
This current intermediate draft of the CHORUS vision document (D3.3) is based on the previous CHORUS vision documents D3.1 to D3.2 and on the results of the six CHORUS Think-Tank meetings held in March, September and November 2007 as well as in April, July and October 2008, and on the feedback from other CHORUS events.
The outcome of the six Think-Thank meetings will not just be to the benefit of the participants which are stakeholders and experts from academia and industry â CHORUS, as a coordination action of the EC, will feed back the findings (see Summary) to the projects under its purview and, via its website, to the whole community working in the domain of AV content search.
A few subjections of this deliverable are to be completed after the eights (and presumably last) Think-Tank meeting in spring 2009

A QoS monitoring system in a heterogeneous multi-domain DVB-H platform
The MobileTV, IPTV, and DVB standards (DVB-H/T) have been defined to offer mobile users interactive multimedia services with quality of service (QoS) consistency analogous to TV services. However, the market has yet to provide effective and economical solutions for the real-time delivery of such services to the corresponding transmitters over multi-domain IP networks. The monitoring system proposed in this paper enables the QoS in the IP networks involved in the delivery of real-time multimedia content to the transmitters to be ascertained. The system utilizes the QoS parameters defined in MPEG-2 Transport Streams to detect problems occurring in the heterogeneous multi-domain IP networks. The ability to detect problems having an adverse effect on QoS allows appropriate control actions to be determined to recover the QoS across the composite IP network. The design and implementation of the proposed QoS-Monitoring system (QoS-MS) is presented, followed by analysis of experimental results that demonstrate the feasibility of the system

A Racial Impact Analysis of HB 936: Accessibility of Electronic Textbooks
The economic and social consequences of the lack of access to technology for students in the Commonwealth of Virginia are real and significant. This report provides a legislative racial impact analysis of House Bill (HB) 936, a proposed bill in the Virginia General Assembly, prohibiting school boards from making electronic textbooks available for students, unless the school board adopts a plan to ensure that e-textbooks are available on or before July 1, 2017. The bill focuses solely on developing a plan for installing prior to implementing electronic textbooks in K-12 classrooms. Electronic textbooks are important as they offer updated content, ease of accessibility, multimedia features to enhance the learning experience, and the ability for educators to customize learning. Delegating this decision to each local school board in Virginia raises important potential racial implications, including the digital divide. Previous research suggests a correlation between the number of students receiving free and reduced lunch and the lack of availability of electronic textbooks. Districts with high rates of students on free and reduced lunch have a high population of minority students. This analysis provides maps that capture the trends on the probability of providing electronic textbooks for high minority areas across the state. The primary recommendation is to advance policy approaches that make electronic textbooks available to all Kâ12 students in the Commonwealth of Virginia
An integrated approach to preparing, publishing, presenting and preserving theses
[Abstract]: This paper describes progress on a project funded by the Australian government to create Free
software; the Integrated Content Environment for research and scholarship (ICE-RS). ICE-RS is a
multi-faceted project which will add value to finished theses by making them available in both
HTML and PDF, as well as providing a mechanism for packaging multimedia theses. The project
will also concentrate on providing services for thesis production, with version control, automated
backup and collaboration services.
The paper begins with the established content management system that is the basis for the
project, ICE-RS , originally developed to create courseware packages. ICE includes distributed, version
controlled collaboration, using word processing software and works on multiple platforms, with
standard document formats. We survey other approaches to content authoring and publishing for
ETDs.
We showcase exploratory work on integration of the thesis writing process with Institutional
Repository software including publishing theses in both PDF and HTML with preservation and
descriptive metadata. The presentation will include demonstrations of thesis production at all stages
of development from proposal to completion.
In a more speculative vein, we will discuss opportunities for institutions to provide new levels of
support for candidates via automated thesis âdashboardâ progress reports, supervisor and examiner
annotation and comment and support for copyright considerations as early as possible in the
process
Evaluation of the interactive multimedia business simulation SPACE (Simulating Project Auditing and Controlling Excellence)
This report presents the evaluation of the computer-based simulation SPACE â Simulating Project Auditing & Controlling Excellence â which is an interactive multiedia business simulation developed in partnership by Andersen Consulting and Siemens AG. The aims of SPACE are fostering self-directed learning and the acquisition of applicable knowledge in the economic domain regarding construction and solution projects of US GAAP. The evaluation was conducted in cooperation with the Institute of Educational Psychology at the Ludwig-Maximilians-University in Munich. The aim of the evaluation was to compare the effectiveness of SPACE with a traditional classroom instruction. Therefore, a problem-based transfer task was designed which assessed learning gains with respect to applicable knowledge in the following areas: (1) strategic knowledge and problem-solving skills, that means selection of appropriate information and strategies to solve a realistic business problem, (2) basic skills to calculate POC and (3) conceptual knowledge, i.e. an understanding of principles and interconnections of concepts in the domain. 38 students of business administration participated in the evaluation. 19 students learned eight hours with SPACE, the other 19 students received a traditional classroom instruction lasting also eight hours in the same subject area of US GAAP. Results show that SPACE was significantly better with regard to strategic knowledge and applying problem solving skills. In other words, the study showed that SPACE is superior to classroom instruction in this area of knowledge acquisition and application. In the other areas of basic skills to calculate POC and conceptional knowledge, differences were not significant between the classroom instruction and SPACE. When SPACE is employed under realistic conditions, i.e. in business, it can be assumed that SPACE is even more superior to classroom instruction.Das computerbasierte Lernprogramm SPACE (Simulating Project Auditing & Controlling Excellence), eine interaktive, multimediale Simulationssoftware, wurde von Anderson Consulting und der Siemens AG entwickelt. SPACE zielt auf die Förderung selbstgesteuerten Lernens und die Vermittlung anwendbaren Wissens. Das Simulationsprogramm behandelt inhaltlich die Kalkulation von Projektdaten auf Basis von US GAAP. Die hier berichtete Evaluationsstudie hatte zum Ziel, die EffektivitĂ€t von SPACE im Vergleich zu einem traditionellen Klassenzimmerunterricht festzustellen. Mit einer problemorientierten Transferaufgabe wurden folgende Dimensionen erfasst: (1) Strategisches Wissen und Problemlösefertigkeiten (hierbei ging es um die Selektion relevanter Informationen und Strategien in Bezug auf eine realistische Problemstellung), (2) Basisfertigkeiten zur Berechnung von POC und (3) konzeptionelles Wissen im Sinne eines VerstĂ€ndnisses von Prinzipien und ZusammenhĂ€ngen innerhalb des behandelten Inhaltsgebietes. An der Studie nahmen 38 Studenten der Betriebswirtschaftslehre teil. 19 Studenten lernten in einem Zeitraum von acht Stunden mit SPACE, die anderen 19 Teilnehmer nahmen an einem achtstĂŒndigen Klassenzimmerunterricht zum selben Inhaltsbereich teil. Hinsichtlich der Dimension "Strategiewissen und Problemlösefertigkeiten" schnitten diejenigen Studenten signifikant besser ab, die mit SPACE lernten. Das Simulationsprogramm zeigte sich somit in Bezug auf diese Dimension der Wissensanwendung dem traditionellen Klassenzimmerunterricht ĂŒberlegen. In den Dimensionen "Berechnung von POC" und "Konzeptionelles Wissen" ergaben sich keine signifikanten Unterschiede zwischen den beiden Untersuchungsgruppen. Es ist anzunehmen, dass SPACE dem traditionellem Unterricht deutlicher ĂŒberlegen ist, wenn das Lernprogramm unter realistischeren Bedingungen, d.h. in Betrieben, eingesetzt wird
