Changing Light: a plethora of digital tools as slides gasp their last?

The title 'Changing Light' reflects the enormous changeover from analogue slides to digital images, both a cultural shift and a physical shift down to the change in light from the smoky beams of dual slide projectors piercing the dark of a classroom, to the bright white classrooms of the digital age. The evidence for the 'death of slides' has been mounting for a number of years and reported by visual resources curators in the US and the UK. In 2005 JISC funded AHDS Visual Arts to report on 'the effects of the digital image revolution on the UK arts education community'; the Association of Curators of Art and Design Images (ACADI), the Association of Art Historians (AAH), and the Art Libraries Society (ARLIS/UK & Ireland) contributed significantly to the Digital Picture initiative. However some of the issues highlighted by the final report are yet to be addressed such as provision of copyright-cleared digital images for use in education. This paper considers what arts education stands to lose from the 'death of slides' in the context of digital images and the plethora of digital presentation tools. As well as a change in light, there is a change from the physical tangible slide technology to the virtual digital image and computing in the cloud

Multimedia courseware: Never mind the quality how much will it cost to develop?

This paper evaluates multimedia courseware costing techniques such as the US Airforce Interactive Courseware Method (Golas, 1993), CBT Analyst (Kearsley, 1985), CEAC (Schooley, 1988) and MEEM (Marshall, Samson, Dugard, & Scott, 1994) against the data from ten multimedia courseware developments. The Relative Error and Mean Absolute Relative Error (MARE) are calculated to allow comparison of the different methods

The Use of Geographical Information Systems in the Urban Communes of Łódź Metropolitan Area

The article presents the results of pilot studies carried out in the cities of Łódź Metropolitan Area. The study concerned the use of geographical information system by the employees of offices of these cities. The interest in the subject of GIS in Polish urban communes results from the assumptions of the EU INSPIRE Directive and the necessity of its implementation in the basic units of territorial division of Poland. The aim of the research was the analysis of the impact of GIS on the sphere of the public participation in the process of local management and the possible use of GIS in the decision making in communes. Research showed what kind of software was used in analyzed communes

Control, Process Facilitation, and Requirements Change in Offshore Requirements Analysis: The Provider Perspective

Process, technology, and project factors have been increasingly driving organizations to offshore early software development phases, such as requirements analysis. This emerging trend necessitates greater control and process facilitation between client and vendor sites. The effectiveness of control and facilitation has, however, not been examined within the context of requirements analysis and change. In this study, we examine the role of control and facilitation in managing changing requirements and on success of requirements gathering in the Indian offshore software development environment. Firms found that control by client-site coordinators had a positive impact on requirements analysis success while vender site-coordinators did not have similar influence. Process facilitation by client site-coordinators affected requirements phase success indirectly through control. The study concludes with recommendations for research and practice

A Conceptual UX-aware Model of Requirements

User eXperience (UX) is becoming increasingly important for success of software products. Yet, many companies still face various challenges in their work with UX. Part of these challenges relate to inadequate knowledge and awareness of UX and that current UX models are commonly not practical nor well integrated into existing Software Engineering (SE) models and concepts. Therefore, we present a conceptual UX-aware model of requirements for software development practitioners. This layered model shows the interrelation between UX and functional and quality requirements. The model is developed based on current models of UX and software quality characteristics. Through the model we highlight the main differences between various requirement types in particular essentially subjective and accidentally subjective quality requirements. We also present the result of an initial validation of the model through interviews with 12 practitioners and researchers. Our results show that the model can raise practitioners' knowledge and awareness of UX in particular in relation to requirement and testing activities. It can also facilitate UX-related communication among stakeholders with different backgrounds.Comment: 6th International Working Conference on Human-Centred Software Engineerin

A microtonal wind controller building on Yamaha’s technology to facilitate the performance of music based on the “19-EDO” scale

We describe a project in which several collaborators adapted an existing instrument to make it capable of playing expressively in music based on the microtonal scale characterised by equal divsion of the octave into 19 tones (“19-EDO”). Our objective was not just to build this instrument, however, but also to produce a well-formed piece of music which would exploit it idiomatically, in a performance which would provide listeners with a pleasurable and satisfying musical experience. Hence, consideration of the extent and limits of the playing-techniques of the resulting instrument (a “Wind-Controller”) and of appropriate approaches to the composition of music for it were an integral part of the project from the start. Moreover, the intention was also that the piece, though grounded in the musical characteristics of the 19-EDO scale, would nevertheless have a recognisable relationship with what Dimitri Tymoczko (2010) has called the “Extended Common Practice” of the last millennium. So the article goes on to consider these matters, and to present a score of the resulting new piece, annotated with comments documenting some of the performance issues which it raises. Thus, bringing the project to fruition involved elements of composition, performance, engineering and computing, and the article describes how such an inter-disciplinary, multi-disciplinary and cross-disciplinary collaboration was co-ordinated in a unified manner to achieve the envisaged outcome. Finally, we consider why the building of microtonal instruments is such a problematic issue in a contemporary (“high-tech”) society like ours
