In this paper, we explore how current technologies are designed to support open innovation, in order to envision future developments and research challenges. A sample of 51 systems has been classified. Surprisingly, we found that most technologies for open innovation are not very innovative because they provide similar features. Typically, users are asked to suggest ideas or solve predefined problems in collaboration with others. By drawing on our review, we identified four types of open innovation systems: idea management system, problem solving system, marketplace system and innovation analysis system. In conclusion, we noted that a key challenge for research and practice is to gain a deeper understanding of how collaboration technologies can be connected with more sophisticated opportunities for reflection and analysis.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129899320","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 sense, researchers have found that trust plays an important role in affecting consumers' purchase behavior. As advances of Internet technology, many consumers tend to read online messages about others' shopping experiences before making purchasing decisions. Thus, informational social influence affects in the decision-making process as well. However, few studies have provided in-depth examination of both impacts from trust and informational social influence in online context. In this study, we explore the moderating effect of informational social influence in a trust-based online shopping model. We conduct a laboratory experiment to verify this model, and find that emotional trust mediates relationships between three trusting beliefs (competence, benevolence, and integrity) and purchase intention. Further, information inconsistency, a particular form of informational social influence, is found to strengthen the relationship between emotional trust and purchase intention. Implications for research and practice are discussed.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128644142","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}

Healthcare professionals often need related e-health information in order to obtain a more comprehensive picture of a patient's health status. There are many obstacles to retrieving information and data from heterogeneous sources. In this paper we show that our ontological layering helps in (a) classifying requests imposed by healthcare professionals when retrieving e-health information from heterogeneous sources and (b) resolving semantic heterogeneities across repositories and composing an adequate answer to issued requests. We use a layered software architectural model based on Generic ontology for Context-aware, Interoperable and Data sharing (Go- CID) software applications, applicable to e-Health environments. Ontological layering and reasoning have been demonstrated with semantic web technologies.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127283051","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 basic idea of the mechanism is that the group members carry out a joint search based on a mediated pheromone matrix. By means of the Borda maximin voting rule, the agents determine contract proposals in each round of the negotiation process which are then used for the adaptation of pheromones or the generation of new contracts, respectively. The new negotiation mechanism is applied to the problem of decentralized lot-sizing in a supply chain. The resulting solution approach for the multi-level uncapacitated lot-sizing problem (MLULSP) is evaluated on the basis of 40 benchmark problems taken from the relevant literature. The derived results come close to those results which are obtained by centralized planning. Moreover, the new mechanism is competitive with other negotiation approaches which have been presented in the literature so far.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127206771","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 the current era in which ICT4D (ICT for Development) has been firmly entrenched on the social and development agenda, researchers have been confronted with the same challenge. This paper reports on the design of an investigation for the evaluation of socio economic outcomes of a national programme of community-based telecentres. The paper describes the challenges that were encountered in developing a suitable design frame to conduct the study. In presenting the research design, we discuss the rationale, and motivations for various design decisions. Additionally the paper highlights the short sightedness of implementers of ICT4D projects in incorporating monitoring and evaluation strategies during the conceptualization and implementation of ICT interventions.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130672187","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}

It uses that framework to analyze the approach taken in Australia for preparing for high levels of renewable energy penetration, demonstrating the importance of adopting a systematic approach to this problem and illustrating the outcomes that can be achieved if that is done. The Australian approach has achieved notable successes to date. However, it is a work in progress that is hampered by contested policymaking and the partial privatization of the Australian electricity industry. The paper suggests ways in which further progress could be achieved. These include refinements to wind (and solar) forecasting, enhanced end-user engagement and improvements to gas industry arrangements and electricity-gas compatibility.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130739070","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 estimate these effects, we used our novel approach that is applicable for any arbitrary hazard function. By utilizing the incidence rates of first primary, microscopically confirmed cases observed in six five-year time periods and 17 cohorts, we found turnovers in the PC and KC incidence rate distributions at old ages. For PC, no systematic changes were revealed in both time period and cohort coefficients during the considered time observation. For KC, however, we found systematically increasing trends for time period coefficients, while trends of birth cohort effect coefficients remain unchangeable during 1975-2004. The proposed approach can be used in the mathematical modeling of different types of carcinogenesis.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131963466","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}

When the filter cache is utilized in a memory system, more than 50% of the power reduction is accomplished due to the filter cache. However, more than 20% of the performance is compromised as well. To minimize the performance loss of the filter cache, this paper proposes a new filter cache predictor model and its algorithm. In our scheme, Mode Selection Bit (MSB) controls selective accesses to a filter cache and a Branch Target Buffer (BTB). The simulation result shows that our solution provides performance improvement, in energy-delay product, up to about 9.1%, compared to previous policies.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130248729","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}
