Over the last decade, computer supported cooperative work (CSCW) has emerged as an identifiable research area that focuses on the role of the computer in group work. CSCW is a generic term which combines the understanding of the nature of group working with the enabling technologies of computer networking, systems support and applications. The paper examines the classes of system which have emerged to support cooperative working. A framework for characterising and describing CSCW systems is presented and four major classes of cooperative system identified. Each of these classes of cooperative system are examined highlighting their general characteristics and applicability to CSCW. 相似文献

We present fieldwork findings from the deployment of an interactive sensing system that supports the work of energy advisors who give face-to-face advice to low-income households in the UK. We focus on how the system and the data it produced are articulated in the interactions between professional energy advisors and their clients, and how they collaboratively anticipate, rehearse, and perform data work. In addition to documenting how the system was appropriated in advisory work, we elaborate the ‘overhead cost’ of building collaborative action into connected devices and sensing systems, and the commensurate need to support discrete workflows and accountability systems to enable the methodical incorporation of the IoT into collaborative action. We contribute an elaboration of the social, collaborative methods of data work relevant to those who seek to design and study collaborative IoT systems. 相似文献

A correlation was developed for predicting limiting mutual diffusion coefficients of gaseous and liquid solutes in normal alkane solvents with carbon numbers ranging from 7 to 28 at temperatures to 570 K. The functional form of the correlation is based on the rough hard sphere theory. The parameters needed in the correlation are the molecular weights and hard sphere diameters of the solute and solvent molecules and molar volume of the solvent. The data used in the development of the correlation included 143 measurements with solute/solvent molecular mass ratios ranging from 0.005 to 2.26 and size ratios ranging from 0.3 to 1.3. The average absolute error in predictions was only 6.3%. When the correlation was used to predict literature values for binary n-alkane systems, the average absolute error was 16.7%. 相似文献

In this paper, we present the theme park as a novel commercial setting and distinct cultural ecology for CSCW research, presenting
challenges to technology designers interested in supporting cultural visiting activities. We report findings from an empirical
field study of theme park visiting by groups. Our account focuses on how visitors encountered the theme park, and how they
worked with or “geared in” to what the park provided in order to pursue leisure activities to their own ends. We further demonstrate
that, whilst theme park visiting features thrilling and fun activities, it also features the prosaic concerns of planning,
parenting and money that connect it to ordinary social life. As such, we present the theme park as a setting in which work
and leisure are intertwined as concerns of both visitors and the park, for producing and consuming theme park experience.
We have focussed on the work of visiting groups to pursue leisure, and their combined use of park-provided and personal technologies
in various “trajectories of interaction” within the park. Our findings point to considerations for the design of services
that connect with park-provided and personal technologies to support group visiting, in theme parks and related settings. 相似文献

Computer support for cooperative work requires the construction of applications that support interaction by multiple users. The highly dynamic and flexible nature of cooperative work makes the need for rapid user-interface prototyping a central concern. We have designed and developed a software architecture that provides mechanisms to support rapid multiuser-interface construction and distributed user-interface management. Rapid prototyping requires mechanisms that make the information determining interface configuration visible, accessible, and tailorable. We developed the architecture as part of a project investigating support for the cooperative work of air traffic controllers. Extensive use of prolonged ethnographic investigation helped to uncover the nature of cooperation in air traffic control. The aim of the architecture is to support an environment in which a multidisciplinary team can experiment with a wide range of alternate user-interface designs for air traffic controllers. Thus, we use examples from this domain to illustrate the architecture 相似文献

Requirements engineering (RE) is an inherently social process, involving the contribution of individuals working in an organizational context. Further, failures in the RE process will potentially lead to systematic failures in the products that are produced as a result. Consequently, the RE process for dependable systems development should itself be considered as a dependable process, and therefore subject to greater scrutiny for vulnerabilities to error. Research on human error has typically focused on the work of individual actors from a cognitive perspective. This paper presents a survey which broadens the view on what contributes to human error by also examining work from the social and organizational literature. This review was conducted to inform efforts to improve the systems development process for dependable systems, and in particular their requirements engineering process 相似文献

The Citywide project is exploring ways in which technology can provide people with rich and engaging digital experiences
as they move through physical space, including historical experiences, performances and games. This paper describes some initial
results and experiences with this project based upon two prototype demonstrators. In the first, we describe an application
in which a search party explores an archaeological site, uncovering enacted scenes within the virtual world that are of a
historical relevance to their particular physical location. In the second, we describe a museum experience where participants
explore an outdoors location, hunting for buried virtual artifacts that they then bring back to a museum for a more detailed
study. Our demonstrators employ a varied set of devices, including mobile wireless interfaces for locating hotspots of virtual
activity when outdoors, to give different experiences of the virtual world depending upon location, task, available equipment
and accuracy of tracking. We conclude by discussing some of the potential advantages of using an underlying shared virtual
world to support interactive experiences across extended physical settings. 相似文献

For the design of new jointed plain concrete pavements (JPCPs), three national calibrations of the AASHTOWare Pavement ME Design have been necessary due to model and database updates. Local calibration is also recommended to better match a state’s experience. To date, 8 states have changed the calibration coefficients to local values, while 11 states have implemented national coefficients. This study presents a review of the national and local calibrations and a comparison in terms of, (1) pavement performance prediction and (2) thickness design. It was found that the difference between the local and national calibrations was significant in terms of predicted pavement performance, but much less with respect to thickness design. Furthermore, a full factorial was conducted to study the impact of various design features on the local calibrations. The results showed that the difference between the national and local calibrations decreased as optimum design features such as short joint spacing were used. 相似文献

Abstract This article is concerned with the problem of improving software products and investigates how to base that process on solid empirical foundations. Our key contribution is a contextual method that provides a means of identifying new features to support discovered and currently unsupported ways of working and a means of evaluating the usefulness of proposed features. Standard methods of discovery and evaluation, such as interviews and usability testing, gather some of the necessary data but fall short of covering important aspects. The shortcomings of these approaches are overcome by applying an integrated and iterative method for collecting and interpreting data about product usage in context. This article demonstrates its effectiveness when applied to the discovery and evaluation of new features for standard Web clients. 相似文献
