Though many results differed, almost all the reviewed studies concurred that the superior parietal lobe plays a major role in the process of mental rotation. The possible confounds (including gender differences, analysis methods, experimental paradigms and controls, etc.) for the different results are discussed. Varied results included lateralization effects, motor component involvement, as well as the activation of the V5/human MT (visual/mid-temporal) area of the brain, which implies that imagined motion may have occurred. Neuroimaging can be a powerful tool for understanding cognitive abilities and limitations. Neuroimaging aids researchers to gain insight into how mechanisms in the human brain function. In combination with other technologies, e.g. eye tracking, this will greatly enhance our ability to comprehend human cognition. This approach to analyzing can provide an important objective measure which could play a significant role in the design of computer systems.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116969812","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}

A number of theoretical papers have made the argument that because of the existence of various technological and psychological constraints, the forms that mass interaction takes, can be understood partly in terms of system dynamics. In particular, it has been suggested that user information overload results in nonlinear feedback loops which impacts on discourse structure. This paper describes an empirical examination of three hypothesized effects of such loops by the analysis of 2.65 million USENET messages posted to 600 newsgroups over a 6-month period. Statistical analysis of the data demonstrated the existence of the hypothesized effects and support the assertion that individual 'information overload' coping strategies have an observable impact on mass interaction discourse dynamics. This in turn suggests that the usability of computer mediated communication technologies can be examined in terms of group-level usability.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116997326","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}

Thereby we focus on the problem of converting different data formats of participants of the supply chain. First results show that XML and its surrounding standards of the XML family highly accelerate and simplify the conversion process. Therefore, XML allows using a common standard on a lower level, without reducing variety on a higher level, due to the use of different XML vocabularies. First, we examine different approaches for solving the transformation problem. Second, we show how XML can actually be implemented for a Web-based integration in supply chains. We present a Java-based prototype that enables document exchange over the Internet using XML business vocabularies for document representation, XSLT for document conversion and presentation, and both DOM and SAX for processing and integrating documents into in-house-systems.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120919315","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}

To offer personalized services in a consistent manner and to speed up the development of such services, we present a Personal Service Environment (PSE) that, besides profile management, provides generic service discovery, content adaptation and service adaptation functionality. The PSE implementation is based on a loosely coupled architecture based on the Web services paradigm. Specific PSE components will be generated on a development and deployment environment for negotiating brokerage agents with learning, anticipating, and adaptive capabilities. These brokerage agents are intended to handle matching and adaptation of service content and logic, ensuring optimal quality of service delivery. We illustrate the implementation of our PSE with a 'Personalized Messaging' prototype, which is based on the concepts of Unified Messaging and Instant Messaging, combined with new mobile network features such as location awareness.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124940009","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}

Our system uses the Object Oriented Bayesian Knowledge Base (OOBKB) design to create a decision model at the most suitable level of detail to guide the information gathering activities, and to produce investment recommendation within a reasonable time. To determine the suitable level of detail we define and use the notion of urgency, or the value of time. Using it, our system can trade off the quality of support the model provides versus the cost of using the model at a particular level of detail. The decision models our system uses are implemented as influence diagrams. Using a suitable influence diagram, our system computes the value of consulting the various information sources available oh the web, uses web agents to fetch the most valuable information, and evaluates the influence diagram producing the buy, sell and hold recommendations.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124950960","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 formal model for autonomous agents to negotiate on the Internet. In our model, the negotiation process is driven by the internal beliefs of participating agents. We empirically identify the relative strength of a group of belief updating methods and show how an agent can change its behavior by adjusting some critical parameters. The advantage of our model is that it is flexible and easy to implement. To show different \"personalities\", one only needs to plug in suitable \"subjective beliefs\" to one's agents. Our results provide directive reference on how these beliefs should be chosen and what values of the related parameters should be assigned.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125065311","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}

In this paper, we hypothesize that a critical success factor for a successful ASP relationship between a provider and a consumer is managing the coordination activities involved. This we believe can be managed using an enterprise architecture which is extended over and coordinated between the service provider and the consumer of the service. To support these premises, we describe a methodology derived from coordination theory that helps in identifying and analyzing the coordination process. We apply this methodology to the ASP value chain and use the results to derive an architecture to support these coordination activities.","PeriodicalId":366006,"journal":{"name":"Proceedings of the 35th Annual Hawaii International Conference on System Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123570150","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}

Moreover, the environment offers integrated communication, coordination and cooperation services that can be added on to the course in order to supplement it. The course on \"Information Technology Applied to Education\" is wholly taught via the Internet though the AulaNet environment. The purpose of the course is to get students to learn to work with information technology as a group, turning them into Web-based educators. The class has been conducted since 1998. This paper reports how the AulaNet was configured and how its services aided in the creation and application of the course during the period from 1998 to 2001.
