GAUGE: Grid Automation and Generative Environment,

CONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 10 2006
Francisco Hernández
Abstract The Grid has proven to be a successful paradigm for distributed computing. However, constructing applications that exploit all the benefits that the Grid offers is still not optimal for both inexperienced and experienced users. Recent approaches to solving this problem employ a high-level abstract layer to ease the construction of applications for different Grid environments. These approaches help facilitate construction of Grid applications, but they are still tied to specific programming languages or platforms. A new approach is presented in this paper that uses concepts of domain-specific modeling (DSM) to build a high-level abstract layer. With this DSM-based abstract layer, the users are able to create Grid applications without knowledge of specific programming languages or being bound to specific Grid platforms. An additional benefit of DSM provides the capability to generate software artifacts for various Grid environments. This paper presents the Grid Automation and Generative Environment (GAUGE). The goal of GAUGE is to automate the generation of Grid applications to allow inexperienced users to exploit the Grid fully. At the same time, GAUGE provides an open framework in which experienced users can build upon and extend to tailor their applications to particular Grid environments or specific platforms. GAUGE employs domain-specific modeling techniques to accomplish this challenging task. Copyright © 2005 John Wiley & Sons, Ltd. [source]

Neonatal seizure detection using multichannel display of envelope trend

EPILEPSIA, Issue 2 2008
Nicholas S. Abend
Summary We aimed to determine whether analysis of EEG envelope trend aids bedside detection of neonatal seizures. Five neonatal EEGs with multiple seizures were used to determine optimal trend parameters for seizure detection. Using these parameters, envelope trends were generated on eight additional EEGs, evaluated by experienced and inexperienced users, and compared to traditional EEG interpretation. Seizures were best detected using envelope trend of 2,6 Hz activity over 20-s epochs. Experienced and inexperienced users identified 88% and 55% of prolonged seizures, respectively, 40% and 6% of brief seizures, and 20% and 0% of slowly evolving seizures. All users identified less than two false positives per hour. Thus, an experienced envelope trend user accurately identified longer seizures but did not identify brief or slowly evolving seizures. Less experienced users were less accurate. Trending may be a useful tool for seizure detection in some neonates. [source]

Cue usage in financial statement fraud risk assessments: effects of technical knowledge and decision aid use

ACCOUNTING & FINANCE, Issue 1 2009
Jean-Lin Seow
M41; M49 Abstract This paper investigates the effects of technical knowledge and decision aid use on financial statement fraud risk assessments made by directors and students. More extreme fraud risk assessments are made when participants identify and process larger (smaller) numbers of diagnostic (non-diagnostic) factors, with technical knowledge driving diagnostic factor identification. Significant decision aid-technical knowledge effects are also found; decision aid use has a detrimental effect on high-knowledge directors while improving performance in inexperienced, low-knowledge students. These results suggest that although decision aids can afford gains in performance in inexperienced users, they can have unintended and/or paradoxical behavioural effects on experienced users.

Learning from leading-edge customers at The Sims: opening up the innovation process using toolkits

R & D MANAGEMENT, Issue 3 2006
Reinhard Prügl
Recently, toolkits for user innovation and design have been proposed as a promising means of opening up the innovation process to customers. Using these tools, customers can take on problem-solving tasks and design products to fit their individual needs. To date, arguments in favor of this new concept have been limited to the idea of satisfying each user's needs in a highly efficient and valuable way. The aim of this empirical study is to extend our knowledge of how users deal with ,the invitation to innovate' and how attractive individual user designs might be to other users. In studying the users of toolkits for the immensely popular computer game The Sims, we found that (1) users are not ,one-time shoppers', in fact, their innovative engagement is rather long-lasting, continuous, evolving, and intense. We also found that (2) leading-edge users do not merely content themselves with the official toolkits provided by the manufacturer. They employ user-created tools to push design possibilities even further. (3) Moreover, individual user designs are not only attractive to the creators themselves; instead, certain innovative solutions are in high demand among other users. Based on our findings, we discuss how toolkits and their users might add to the process of innovation in general. We argue that toolkits could serve as a promising market research tool for guiding a firm's new product development efforts. Furthermore, toolkits may serve as a crčche for interested but inexperienced users who could evolve into leading-edge users over time. These innovative users might then be integrated into more radical product development efforts. [source]
