Simulation results from detailed Korean power-flow models show that the controllers can provide significant improvements in security, quality and efficiency of power system voltage monitoring and control. Operating within a time scale ranging from tens of seconds to a few minutes, the controllers can act upon voltage alarms and voltage insecure conditions to maintain prescribed voltage profile and adequate VAR margins. The control actions include continuous adjustment of generator VAR outputs as well as switching of discrete VAR support devices such as shunt capacitor banks. This paper extends an earlier discrete version of the controller developed at Washington State University and tested at Bonneville Power Administration into a hybrid voltage controller. This paper tests the implementation and application of the previously developed discrete as well as the proposed hybrid controllers in Korean power system models.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115085033","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 explore this issue by investigating how eight approaches to understanding or modeling collaboration could be used to improve technologies that support a change management process. Some approaches are ostensive, defining how collaboration should be achieved. These approaches provide ways of documenting, analyzing, simulating, and automating the process. Other approaches are performative, describing actual collaboration behavior. These approaches reveal the variability in collaboration and deviations from the intended process. Technologies could benefit from and facilitate both types of approaches by recording collaborative events for later analysis. We conclude by considering ways that modeling collaboration could contribute to requirements analysis, new collaboration capabilities, adoption, and maximizing benefit from technologies.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122437120","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 level of complexity, interaction and interdependence among various components make it difficult to design, develop, and analyze such systems as a whole. In particular it is difficult to foretell the effect of proposed changes and to evaluate alternative architectures. Adoption of a model-driven approach, coupled with sound Verification and Validation (V and V) techniques can provide a key solution for making qualitative and quantitative predictions about the possible system behaviors. This paper details a case study in Verification and Validation of a Service Oriented Architecture called MCSOA (Multi Channel Service Oriented Architecture). It is part of a larger exercise to integrate a model-driven approach into MCSOA Software Development for the US Department of Defense. We show how support for hierarchical and abstraction features, concurrency, and both synchronous and asynchronous communications in Colored Petri Nets (CPNs) enable modeling real-world SOA implementations to perform V and V and quality assurance required for DoD deployments.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122622361","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}

While it seems appropriate to provide laypersons with educational health information, prior research emphasizes the importance of understanding behavioral responses when communicating risk information. In order to systematically explore and analyze these relationships in the context of online health information, a new diabetes risk calculator website was developed to serve as an intervention in which the presence of personalization and interactive feedback could be manipulated for randomized experimentation. The website was integrated with pre- and post-intervention surveys in order to assess users in terms of information usage and risk perceptions. In two preliminary experiments, there was a small, unexpected negative impact of personalization on multiple measures of information usage. The implications of these results are discussed in the context of improving the presentation of online risk information for practical and experimental evaluation purposes.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122079101","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}

Some studies have shown that companies which have good IT governance models generate superior returns on their IT investments than their competitors. However, there is a lack of scientific research confirming that effective IT governance results in better financial performance. In this paper, we verified if companies which have adopted IT governance mechanisms improve their financial performance, examining changes on performance pre and post adoption controlling for industry mean changes. We found that companies which have adopted IT governance practices improved their performance when compared to the control group, especially regarding about profitability measures. Furthermore, we found that effects of IT governance mechanisms' adoption on financial performance are stronger in the year following adoption than in the year which IT governance was adopted.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122097736","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 explore, from the recruiters' perspective, staffing quality improvements and limitations since beginning to use e-recruiting services, the most frequent requests emailed by recruiters to an external e-recruiting service, and the criteria recruiters associate with high e-service quality and how e-service quality can be enhanced. We interviewed 73 recruiters and content-analyzed a large data set of e-mail communications between recruiters and service personnel of an e-recruiting portal for university graduates. Surprisingly, recruiters judge the quality of e-recruiting services primarily by the quantity and not necessarily on the quality of applications, high number of visits to the website, clicks on published job ads, page impressions, successful placements, the size of the applicant pool, and the quality of cooperation with other media channels so as to reach more applicants.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122136828","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}

These portals need to be both smart and user sensitive, able to identify and select resources of relevance to a user community, describe them in ways that facilitate user assessments of quality and relevance, and provide efficient and effective search functionality that can be tailored to individual information needs. The domain expertise required to select and describe resources in this manner is a key to the efficacy of such portals, with their viability dependent on the sustainability and scalability of their resource identification, selection and description processes.

Much is written about this topic. There are methods and tools available, home-grown and commercial, which attempt to make handling product line variations practical. The focus of these methods is on supporting software development; that is, handling variations in the code core assets. However, there are non-code core assets and they also have variations. For example, there are marketing roadmaps, requirement specifications, test cases, process definitions, and all kinds of documentation including user guides, to name just a few. These core assets also have to implement the required variations of the product line and need to do so in a consistent way or there will be incompatible implementations and resultant inefficiencies. The approach to variation we are suggesting takes an organization-wide perspective, covering the entire gamut of core assets not just the code We describe the definition, implementation, and management, including tools support, of a few essential variations throughout the organization to make handling product line variations more efficient and effective.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128428423","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 current practice, software developers lack practical means to determine the full functional behavior of programs under development, and even the most thorough testing can provide only partial knowledge of behaviors. Thus, an effective technology for revealing software behaviors could have a positive impact on software understanding. This paper describes the emerging technology of function extraction (FX) for computing the functional behavior of programs and how the knowledge of program behavior can be used in user-directed program exploration for understanding and verification. We explore how the use of FX technologies can transform methods for functional verification of software. Several examples are presented illustrating the FXplorer interface and its use in exploring the behavior of programs, a capability that, without function extraction technology, has not been possible until now.","PeriodicalId":211759,"journal":{"name":"2009 42nd Hawaii International Conference on System Sciences","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128603874","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}
