The role of healthcare workflowmanagement by use of IT is to adjust the contributions of those organizations or units in terms of timing, quality and functionality. Some of these difficulties can be traced back to the heterogeneous nature of healthcare organizations. Professionals require a certain degree of autonomy, whilst workflow management requires a certain degree of standardization. Organizations or units need goals that fit to their specific practice, workflow management requires cooperative goals, or at least, goals that do not conflict. Also, standardization is needed to make full mutual adjustment of organizations possible, even though such standardization may unnecessarily complicate the way of working. As a result, a dedicated business transformation may be necessary. Healthcare organizations have to rethink their boundaries and have to make strategic alliances to be able to cope with the changes in the environment.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2004-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131080602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper concerns one of these: relationships based on trust and reputation. Recent studies on simple reputation systems for e-Businesses such as eBay have pointed to the importance of such rating systems for deterring moral hazard and encouraging trusting interactions. However, despite numerous studies on trust and reputation systems, few have taken studies across disciplines to provide an integrated account of these concepts and their relationships. This paper first surveys existing literatures on trust, reputation and a related concept: reciprocity. Based on sociological and biological understandings of these concepts, a computational model is proposed. This model can be implemented in a real system to consistently calculate agents' trust and reputation scores.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115601848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes a framework for testing the efficacy of a price-responsive load on a uniform-price last-accepted offer and a soft-cap market. Experimental evidence to date, based on uniform-price market testing has shown an ability of price-responsive load to mitigate high volatility and average price. The paper addresses a process to validate these results as well as our hypothesis that price-responsive load mitigates high soft-cap market price behavior, such as that observed in California.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123062257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a unified approach to data transfer that facilitates conversion between the two concepts, as well as a flexible technique for implementing arbitrary event notification in an object-oriented way. A unified input/output library that simplifies error handling and ensures correct opening and closing of streams rounds up the proposed extensions to an operating system.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117337504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Case study: the relationship between a global outsourcing company and its global IT services supplier","authors":"Dr. Erik Beulen, Pieter Ribbers","doi":"10.1109/HICSS.2002.994314","DOIUrl":"https://doi.org/10.1109/HICSS.2002.994314","url":null,"abstract":"The article describes a case study of an Asian information technology (IT) outsourcing partnership in the discrete manufacturing industry. Interviews with business and IT executives of both the outsourcing company and the IT supplier provided the necessary insights. Nowadays, many organizations in discrete manufacturing move their plants to Asian countries or other lower wage countries. Most IT suppliers in Asia are relatively inexperienced with the management of IT-outsourcing relationships. But not only are the IT suppliers inexperienced, also the outsourcing companies do not have track records in the management of IT-outsourcing relationships. Moreover, besides the level of experience also cultural issues play an important role in this matter. Contrary to the level of experience, the cultural factor will not change over the years. The article aims to provide a better understanding of managing IT-outsourcing partnerships in developing Asian countries on the basis of an IT-outsourcing partnership model.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125011130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors have developed several techniques for visualizing large amounts of data including contouring, animated flows, and 3D visualization. These techniques have been completely integrated into PowerWorld Simulator, an offline system study tool for use in the energy industry. Integrating these visualization techniques with real-time data sources, such as those available in energy control centers, however, has presented a separate challenge to the wide dissemination of these visualization abilities. The paper presents a case study of integrating these abilities with control centers that utilize the Plant Information (PI) System for data storage and archival. Projects have been completed that integrate these visualization techniques into control centers for Commonwealth Edison in Lombard, Illinois and City Water Light and Power in Springfield, Illinois. A separate pilot project has also been completed with the Tennessee Valley Authority.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125685547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Global applications of collaborative technology","authors":"R. Davison, G. de Vreede","doi":"10.1109/HICSS.2002.993874","DOIUrl":"https://doi.org/10.1109/HICSS.2002.993874","url":null,"abstract":"Over the course of the last decade, the role played by collaborative technology applications has become increasingly important. The range of contexts in which these applications have been used includes (inter)-organisational communication and decision making, through distributed software inspections, to virtual education initiatives. The applications themselves include various forms of groupware technology such as group (decision) support systems, electronic mail, shared calendaring applications, document management systems, video and audio conferencing, and the like. Much of the technology has been developed within the cultural milieu of North America, and to a lesser extent Western Europe and Australasia. This is evidently important, since the technology has been imbued with the values present in these cultures, and consequently the technologies themselves may be culturally attuned to the needs and preferences of workers in these contexts. Nevertheless, the application domain is geographically and culturally much broader. Thus, not only do we see distributed groups within a single country, but also groups with members from many different countries. The application contexts thus span both time zones and cultures, involving considerable adaptation, interpretation and structuration of the technology to fit local norms and behaviours. In the future, we believe that these distributed applications of the technology will become increasingly prevalent as the globalisation of work intensifies and receives increased attention. We are delighted to present two papers in this minitrack which address some of the key issues in the Global Application of Collaborative Technology from a variety of perspectives. In our first paper, Suprateek Sarker and Sundeep Sahay consider IS development as conducted by USNorwegian virtual teams. They employ an ethnographic approach to focus on the communication patterns of the individual team members and identify some critical inhibitors of successful collaboration. In the second paper, V. Ramesh and Alan Dennis write about global software development using cases from three Indian multinational technology firms. Given the specific characteristics of the ways in which their teams developed, they suggest that these teams should be re-characterised as object oriented teams. Such teams strive to de-couple team members through the use of well-defined processes and semantically rich media. These media added meaning to the information by clarifying, extending, and constraining the information itself, and enriching it by collecting statistics, and providing the ability to filter and view the information in other forms.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114894484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both the structure of the resource allocation and the resulting behavior of the network are explored for each method.

However, current service composition solutions seem to support either highly dynamic discovery or else very loosely coupled service development, but not both. We propose a facilitator service mechanism that can leverage \"reflected\" XML-based specifications (borrowed from the web service domain) to direct and enable coordinated sequences of message exchanges (conversations) between services. We extend the specification of a message exchange with the ability to specify transformations to be applied to both inbound and outbound documents. We call these extended message exchanges transformational interactions. The facilitator service can use these transformational interactions to allow service developers to decouple internal and external interfaces. This means that services can be developed and treated as pools of methods that can be composed dynamically.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124072215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
