The advent of the World Wide Web (WWW) and the emergence of Internet commerce have given rise to the web as a medium of information exchange. In recent years, the phenomenon has affected the realm of transaction processing systems, as organizations are moving from designing web pages for marketing purposes, to web-based applications that support business-to-business (WEB) and business-to-consumer (B2C) interactions, integrated with databases and other back-end systems (Isakowitz, Bieber et al., 1998). Furthermore, web-enabled applications are increasingly being used to facilitate transactions even between various business units within a single enterprise. Examples of some of the more popular web-enabled applications in use today include airline reservation systems, internet banking, student enrollment systems in universities, and Human Resource (HR) and payroll systems. The prime motive behind the adoption of web-enabled applications are productivity gains due to reduced processing time, decrease in the usage of paper-based documentation and conventional modes of communication (such as letters, fax, or telephone), and improved quality of services to clients. Indeed, web-based solutions are commonly referred to as customer-centric (Li, 2000), which means that they provide user interfaces that do not necessitate high level of computer proficiency. Thus, organizations implement such systems to streamline routine transactions and gain strategic benefits in the process (Nambisan & Wang, 1999), though the latter are to be expected in the long-term. Notwithstanding the benefits of web technology adoption, the web has ample share of challenges for initiators and developers. Many of these challenges are associated with the unique nature of web-enabled applications. Research in the area of web-enabled information systems has revealed several differences with traditional applications. These differences exist with regards to system development methodology, stakeholder involvement, tasks, and technology (Nazareth, 1998). According to Fraternali (1999), web applications are commonly developed using an evolutionary prototyping approach, whereby the simplified version of the application is deployed as a pilot first, in order to gather user feedback. Thus, web-enabled applications typically undergo continuous refinement and evolution (Ginige, 1998; Nazareth, 1998; Siau, 1998; Standing, 2001). Prototype-based development also leads web-enabled information systems to have much shorter development life cycles, but which, unlike traditional applications, are regrettably developed in a rather adhoc fashion (Carstensen & Vogelsang, 2001). However, the principal difference between the two kinds of applications lies in the broad and diverse group of stakeholders associated with web-based information systems (Gordijn, Akkermans, et al., 2000; Russo, 2000; Earl & Khan, 2001; Carter, 2002; Hasselbring, 2002; Standing, 2002; Stevens & Timbrell, 2002). Stakeholders, or organizational members participating in a common business process (Freeman, 1984), vary in their computer competency, business knowledge, language and culture. This diversity is capable of causing conflict between different stakeholder groups with regards to the establishment of system requirements (Pouloudi & Whitley, 1997; Stevens & Timbrell, 2002). Since, web-based systems transcend organizational, departmental, and even national boundaries, the issue of culture poses a significant challenge to the web systems’ initiators and developers (Miles & Snow, 1992; Kumar & van Dissel, 1996; Pouloudi & Whitley, 1996; Li & Williams, 1999).

In response to the increasing difficulties facing museums that attempt to work within a pluralist framework as a strategy for representing cultural diversity, this essay argues for the need to move beyond a characterisation of museum work as either progressive or conservative, pluralist or consensual. Central to my arguments is an attempt to extend our understanding of possible narrative structures in museums by focusing on questions of style as much as of content. I do this by looking back at two case studies in which questions around the political intent of narrative structures were determined as much by the form of the exhibition as by its content. This focus enables are cognition that fragmentary narrative styles are not by definition associated with alack of strong narratives. Quite the contrary. An alternative approach to exhibition making might therefore lie in an approach that moves away from eclecticism but does so not by returning to progressive, chronological narratives but by privileging an understanding of 'shared experience'. I attempt to open up what I mean by this term towards the end of the essay.

This article is concerned with interactions between the natural and the human sciences. It examines a specific late 19th-century episode in their relationship and argues that the schism between the two branches of knowledge was due to cognitive factors, but consolidated through the social dynamics of institutionalized disciplines. It contends that the assignment of a social function to the human sciences to compensate for the self-destructive tendencies inherent in the technological society was expressed even by those, at the end of the 19th century, who were fervent advocates of a science- and technology-driven modernization.

We measured the effects of coherent motion of one set of dots on the perceived location of Gaussian envelopes formed by luminance modulation of a second set of dots. Perceived shifts in envelope location in the direction of coherent motion were obtained even when the dots forming the envelopes did not physically move in the direction of coherent motion. In such cases, perceived shifts coincided with stimulus configurations that permitted motion integration of the envelope dots with the coherently moving dots, for example, when envelope dots moved in random directions as opposed to being static. In subsequent experiments we explored the type of motion integration underlying the positional shifts obtained. We discounted the possibility that the visual system incorrectly attributes motion signals associated with coherently moving dots to envelope dots by demonstrating that positional shifts could be obtained even when the coherent dots were laterally displaced to either side of the envelope dots such that the regions occupied by the dots did not overlap. We also discounted spatio-temporal summation within the receptive fields of low-spatial-frequency motion-sensitive mechanisms by demonstrating that positional shifts persisted even when the dot displays were high-pass filtered. These results, coupled with the observation that the proportion of coherently moving dots required to produce positional shifts correlated well with global motion thresholds measured for the same dot configurations, suggests that visual processes which underlie motion-dependent positional shifts are based at least in part on cooperative interactions of the type implicated in global motion.

The cutting angle method for global optimization was proposed in 1999 by Andramonov et al. (Appl. Math. Lett. 12 (1999) 95). Computer implementation of the resulting algorithm indicates that running time could be improved with appropriate modifications to the underlying mathematical description. In this article, we describe the initial algorithm and introduce a new one which we prove is significantly faster at each stage. Results of numerical experiments performed on a Pentium III 750 Mhz processor are presented.

This article is based on two related research questions. First, what is the level of disclosure on ethnic minorities in the two sectors of the U.K. economy that historically have employed the most ethnic minorities: the banking and retail sectors? And secondly, what influences the (non)disclosure? It specifically investigates the level of disclosures from 1935 to 1998 and situates them within the changing social, political and economic context of this period. It is contended that the changing pattern of disclosure during this period can be understood with reference to changes in the political strategies for managing the threat of racism adopted by successive governments. The article provides some tentative theoretical reflections on the nature of the racism problematic and the way in which power may be seen to operate through (non)disclosure in this particular instance.

In Australia from 1992 to 1999 Jeff Kennett led the Liberal state government in Victoria. Under his leadership an important vision statement for the arts was produced, and ambitious redevelopments of Victoria’s major cultural institutions were undertaken. Kennett’s ‘vision’ included reforms to Arts Victoria (the state-based arts funding agency) and a radical revision of how the arts were to be subsidised. This represented a wholesale adoption of a new policy approach which saw the arts and culture as an industry which could benefit, in particular, the development of cultural tourism for the state of Victoria. This paper argues that while the arts could be seen to have benefited from the Kennett government’s largesse, some parts of the arts sector were excluded and subjected to censorship. Based on both primary and secondary sources, we argue that in this period, the work of artists which expressed a politically dissenting view was actively discouraged.
