The social role of design representation

Design representation is a crucial part of all design activity. Representations provide a vehicle through which design ideas and decisions are explored, communicated and recorded. Since representation is so fundamental to design, it follows that a deep understanding of the nature and use of representation has the potential to improve current design practice. While there is recognition in the IS literature of the importance of representation, previous IS research has focused almost entirely on the functional aspects of representation, in particular modelling to support various methodologies or particular aspects of design such as database, object-oriented or process modelling. Since the development of an information system is a socio-technical process, this paper argues that we need to understand how representations can facilitate both the specification of the artefact, and the social aspects of design. This paper explores the use of design representation by real-world practitioners. It identifies two hitherto neglected social purposes of representation employed by designers when interacting with clients or users: selective focus, and promotion. The paper concludes by noting that as IS faces increasingly complex design challenges it is timely to examine our understanding of all aspects of design representation including its role in facilitating the social aspects of design.

The structural and behaviourial barriers to sustainable real estate development

Sustainable real estate development appears, on literal translation of both terms, to be an oxymoron - however it is a concept that the real estate profession needs to embrace knowledgably. On one hand it can be argued that real estate development is required for continued economic growth and the adoption of sustainability measures is required to mitigate climate change and global warming. Over the last few years there has been growth in the number of sustainability tools available to designers and operators of buildings. For example, in the US the LEED scheme enables designers to assess the environmental impact of their design and to benchmark the sustainability of the design against industry recognised criteria. LEED follows a similar format to the UK’s Building Research Establishment Environmental Assessment Method (BREEAM) introduced in 1990 and the Australian ‘GreenStar’ introduced in 2004. Even though there are an increasing number of sustainability tools available to designers, it still remains that the degree of uptake of the tools has been sporadic. This paper discusses the barriers to sustainable real estate development. Firstly it identifies the barriers to uptake and secondly it establishes the structural barriers in the market which prevent the wider uptake of tools.

Building surveyors in Australia : an emerging profession

Australian and UK Building Codes undergo revision to improve the health and safety standards in the built environment and reflect wider social and technological changes. In the 1990s both countries changed to the option for designers to provide alternative solutions, where designers provide calculations to demonstrate that the codes are satisfied but not through the traditional deemed to satisfy route. Other social and legislative changes have had an impact on the profession. In the UK the Institute of Building Control, the equivalent of the Australian Institute of Building Surveyors responded by joining the Royal Institution of the Chartered Surveyors. Thus it has become part of the largest surveying professional body, what does that mean for the profession? This paper compares the Australian and UK professions and looks at some of the issues affecting their future direction.

Prophet and Loss is a contemporary music theatre performance presented in Wyselaskie Hall which tells the stories of those bereaved by a work-related death, and traumatised by the resulting complex legal processes.

Development of DAL and DAPL languages for building distributed applications

A common characteristic among parallel/distributed programming languages is that the one language is used to specify not only the overall organisation of the distributed application, but also the functionality of the application. That is, the connectivity and functionality of processes are specified within a single program. Connectivity and functionality are independent aspects of a distributed application. This thesis shows that these two aspects can be specified separately, therefore allowing application designers to freely concentrate on either aspect in a modular fashion. Two new programming languages have been developed for specifying each aspect. These languages are for loosely coupled distributed applications based on message passing, and have been designed to simplify distributed programming by completely removing all low level interprocess communication. A suite of languages and tools has been designed and developed. It includes the two new languages, parsers, a compilation system to generate intermediate C code that is compiled to binary object modules, a run-time system to create, manage and terminate several distributed applications, and a shell to communicate with the run-tune system. DAL (Distributed Application Language) and DAPL (Distributed Application Process Language) are the new programming languages for the specification and development of process oriented, asynchronous message passing, distributed applications. These two languages have been designed and developed as part of this doctorate in order to specify such distributed applications that execute on a cluster of computers. Both languages are used to specify orthogonal components of an application, on the one hand the organisation of processes that constitute an application, and on the other the interface and functionality of each process. Consequently, these components can be created in a modular fashion, individually and concurrently. The DAL language is used to specify not only the connectivity of all processes within an application, but also a cluster of computers for which the application executes. Furthermore, sub-clusters can be specified for individual processes of an application to constrain a process to a particular group of computers. The second language, DAPL, is used to specify the interface, functionality and data structures of application processes. In addition to these languages, a DAL parser, a DAPL parser, and a compilation system have been designed and developed (in this project). This compilation system takes DAL and DAPL programs to generate object modules based on machine code, one module for each application process. These object modules are used by the Distributed Application System (DAS) to instantiate and manage distributed applications. The DAS system is another new component of this project. The purpose of the DAS system is to create, manage, and terminate many distributed applications of similar and different configurations. The creation procedure incorporates the automatic allocation of processes to remote machines. Application management includes several operations such as deletion, addition, replacement, and movement of processes, and also detection and reaction to faults such as a processor crash. A DAS operator communicates with the DAS system via a textual shell called DASH (Distributed Application SHell). This suite of languages and tools allowed distributed applications of varying connectivity and functionality to be specified quickly and simply at a high level of abstraction. DAL and DAPL programs of several processes may require a few dozen lines to specify as compared to several hundred lines of equivalent C code that is generated by the compilation system. Furthermore, the DAL and DAPL compilation system is successful at generating binary object modules, and the DAS system succeeds in instantiating and managing several distributed applications on a cluster.

Perceptions and misperceptions of computing careers

Two issues were addressed. 1. Women are underrepresented in computing courses and in the computing workplace. Despite almost two decades of recognition of the issue and of intervention to correct it, the proportion of women in computing continues to decline. 2. There is a shortage of people with appropriate skills and qualifications in computing, and, more specifically, a need for people with particular personality attributes. There is an increasing demand for computing personnel to have good communication and interpersonal skills, but the predominant personality types of computing people do not include these characteristics. The research relating to the underrepresentation of women was conducted as a series of interviews with university students, female computing professionals and secondary school girls. The main findings of these studies were: 1) schoolgirls are interested in careers that are interesting and varied and provide opportunities for interaction with others; 2) schoolgirls perceive computing as involving working alone; 3) women working in computing describe careers that are interesting, varied, and people-oriented; 4) tertiary computing students equated 'computing' with 'programming'; and 5) single interventions are unlikely to result in individuals in the targeted group deciding to study computing. The perception of schoolgirls that computing involves working alone, which is reinforced by many tertiary computing courses, suggested that the type of person who is likely to be attracted to computing is one who would prefer to work alone. It was predicted that schoolboys would have similar perceptions of computing. Thus, computing is likely to attract students who would prefer to work alone. For various social and stereotypical reasons addressed by previous research, these students will be predominantly male. In the final study, preferred Myers-Briggs Type Indicator and Strong Interest Inventory personality types were suggested for computer programmers, systems designers and systems analysts. The existing literature and the 'types' of 72 study participants tended to confirm that 1) certain personality types are overrepresented in computing; 2) these types are well suited to programming and design tasks; and 3) there is an underrepresentation of individuals who have the combination of analytical, communication and people skills that are required particularly of analysts but also of many others working in computing today. Interviews with participants supported the earlier findings that computing careers are perceived by students to be technical and involve working in isolation, but for many computing people this is not the reality.

Application of hermeneutics to studying an experience mining process

In this paper we investigate an approach to eliciting practitioners’ problem-solving experience across an application domain. The approach is based on a well-known ‘pattern mining’ process which commonly results in a collection of sharable and reusable ‘design patterns’. While pattern mining has been recognised to work effectively in numerous domains, its main problem is the degree of technical proficiency that few domain practitioners are prepared to master. In our approach to pattern mining, patterns are induced indirectly from designers’ experience, as determined by analysing their past projects, the problems encountered and solutions applied in problem rectification. Through the cycles of hermeneutic revisions, the pattern mining process has been refined and ultimately its deficiencies addressed. The hermeneutic method used in the study has been clearly shown in the paper and illustrated with examples drawn from the multimedia domain. The resulting approach to experience elicitation provided opportunities for active participation of multimedia practitioners in capturing and sharing their design experience.

Writing public space : design, philosophy, art

Among the factors explaining the emotional poverty of contemporary urban spaces is the dissociation of those who think, design and adorn them. Using his experience in designing high profile public artworks in Australia, notably Relay (Homebush Bay, Sydney, 2000 Olympics), Nearamnew (Federation Square, Melbourne) and Solution (Docklands, Melbourne), Paul Carter argues that a new dialogue between designers, philosophers and artists is urgently needed. The basis of this dialogue will be an expanded notion of graphicality, a new engagement with the discursive character of public space, and the evolution of postrepresentationalist art practices that make surface the psychic violence and cultural waste involved in the provision of new functionallydefined “places”. This paper traverses a number of projects: Relay (1998‑2000), Nearamnew (1998‑2003), Solution (2002), Save the Wall (2004‑) Golden Grove (2004‑).
