This paper discusses the development of a particular spatial display medium, the virtual acoustic display. Although the technology can stand alone, it is envisioned ultimately to be a component of a larger multisensory environment and will no doubt find its greatest utility in that context. A general philosophy of the project has been that the development of advanced computer interfaces should be driven first by an understanding of human perceptual requirements, and secondarily by technological capabilities or constraints. In expanding on this view, the paper addresses why virtual acoustic displays are useful, characterizes the abilities of such displays, reviews some recent approaches to their implementation and application, describes the research project at NASA Ames in some detail, and finally outlines some critical research issues for the future.

Service Theory

Customer participation is one of the critical research issues in service management. This study draws on the client participation concept to explore the content and levels of customer participation in public services (Lithuanian elderships). By integrating Unified Service theory, Service Dominant logic, and using a research design with 12 interviews and 600 participating customer survey, the study confirms the three level customer participation model, identifies four categories of participating customers and shows how sociodemographic characteristics affect customer participation level. Data suggest that public service providers need to pay attention to customer participation management (identification, selection, education and motivation).

Expected Benefits

In the current economic climate, public administrations are looking for ways to improve their service provision and to increase their efficiency. A great long-term public sector concern is the need for restructuring structures and processes to improve efficiency and effectiveness (Beynon-Davies & Williams, 2003). Shared service centers (SSCs) are gaining importance in public administration as a means to innovate, reduce costs, and increase service levels (Janssen & Joha, 2004b). The SSC is a business model in which selected functions are concentrated into a semi-autonomous business unit with management structures that promote efficiency, value generation, and cost savings in a manner akin to companies competing in an open market (Bergeron, 2002). By unbundling and centralizing activities, the basic premise for a SSC seems to be that services provided by one department or agency can be provided to others with relatively few efforts. Within public agencies there is a debate about which kind of services are suitable to share, how to obtain the expected benefits and how to organize SSCs. Currently, SSC implementations include several, relatively easy-to-standardize, functions like the concentration of administrative processes for handling human resources and procurement for all ministries, and the maintenance and control of information systems of several local agencies in a SSC (e.g., http://www.sharedservicesbijdeoverheid.nl/). Clearly, there is no one-size-fits-all business model that incorporates all benefits and has no negative aspects. The goal of this research is to explore the concept of shared service centers and to present an overview of critical research issues with respect to its governance and design. The structure of the article is as follows. In the following section, we discuss the theoretical background. Thereafter we present the main drivers for shared service centers. Section four provides an overview of the critical research issues and in section five we present future trends. Finally in section six, conclusions are drawn.
