The task-technology-fitness framework indicates which groups of medium or technology are appropriate to choose according to the task to be performed, when collaborating with others. We have here presented the extended version of the task-technology-fitness framework, according to how Statoil ASA's employees use SMS, e-mail, instant messaging and audio (phone call), in different collaborative tasks. In total, there were 333 out of 747 respondents who participated in the survey. The results reveal that SMS and Instant Messaging are not seen as efficient or well suited communication channels for collaborative tasks. E-mail seems to be favorable among the respondents for the collaborative tasks, while audio (phone call) follows closely. The results are important in that they indicate when SMS, e-mail, instant messaging and audio (phone call) are appropriate to use.

Consequently, this has rendered many of the existing conventional security countermeasures less effective for mobile agents. In this paper, we propose a new philosophy of trust enhanced security, which advocates a paradigm shift for mobile agent security solutions: from security-centric to trust-centric with the aim of providing improved security and performance of mobile agents. We first examine the problem of uncertainty in behavior induced by the security assumption violations by mobile agents; we then propose a trust enhanced security approach and argue for the need for a paradigm shift to trust-centric solutions. Next we identify a list of general design requirements for the trust-centric solutions and outline the new architectural design which supports the new trust enhanced security philosophy in practice.

When a wide range of malicious activity needs to be tested, a large overhead is incurred in scanning for malicious code and checking internal failures. Large projects also have multi-functional teams working and any lack of communication or overlooks in design can lead to unchecked security holes when the system is integrated. Moreover, it is not always easy to test the whole system for security and accuracy in preventing attacks because one can never develop a test plan for that which one is unaware of, such as a specialized attack by a hacker that compromises a system. Therefore, in this paper we develop a dynamic approach for testing software components in using multiple aspects of testing with high accuracy. We also present new techniques that provide for an automated system architecture that provides for a scalable and flexible distributed testing mechanism capable of handling newer threats at very short notice.

Whilst it is often recognized that information gathered for the ontology modeling process can describe naturally the scientific knowledge and can be used for interoperation among heterogeneous systems (by establishing a global schema, for instance), it may also be used to create data structures, including database schema and initial code signatures, containing metadata and semantics for their applications. The aspects involved in the translation of ontology models into suited metadata, however, can render in wasted efforts and useless schemas for scientific applications. This paper explores an approach to generate semiautomatically appropriate data structures for handling scientific information.

Though many observe that links display strong source-centric locality, for example, in terms of administrative domains and hosts, most Web ranking analysis to date has focused on the flat page-level Web linkage structure. In this paper we develop a framework for link-based collaborative ranking of the Web by utilizing the strong Web link structure. We argue that this source-centric link analysis is promising since it captures the natural link-locality structure of the Web, can provide more appealing and efficient Web applications, and reflects many natural types of structured human collaborations. Concretely, we propose a generic framework for source-centric collaborative ranking of the Web. This paper makes two unique contributions. First, we provide a rigorous study of the set of critical parameters that can impact source-centric link analysis, such as source size, the presence of self-links, and different source-citation link weighting schemes (e.g., uniform, link count, source consensus). Second, we conduct a large-scale experimental study to understand how different parameter settings may impact the time complexity, stability, and spam-resilience of Web ranking. We find that careful tuning of these parameters is vital to ensure success over each objective and to balance the performance across all objectives","PeriodicalId":315775,"journal":{"name":"2006 International Conference on Collaborative Computing: Networking, Applications and Worksharing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125874930","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}
