Using data from 154 firms, it is shown that good internal business/IT alignment leads to better and more accurate provider control processes which in turn improve service level agreements. The paper contributes to the literature in linking internal governance with external IT service quality, and by disclosing a largely neglected influence of alignment on governance and control processes.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"6 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":"130580755","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}

Earlier research in trust-aware systems have shown that the ability of trust-based systems to make accurate predictions coupled with their robustness from shilling attacks make them a better alternative than traditional recommender systems. In this paper we propose an approach for improving accuracy of predictions in trust-aware recommender systems. In our approach, we first reconstruct the trust network. Trust network is reconstructed by removing trust links between users having correlation coefficient below a specified threshold value. For prediction calculation we compare three different approaches based on trust and correlation. We show through experiments on real life Epinions data set that our proposed approach of reconstructing the trust network gives substantially better prediction accuracy than the original approach of using all trust statements in the network.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"26 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":"123874080","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}

An electronic health record system (EHR) is one of the tools to achieve these goals. Hospitals are nevertheless lagging behind industry in implementing IT systems to support their core business processes. Eighteen case studies were conducted among Dutch hospitals to examine the EHR system implementation. Through seventy three interviews with key stakeholders, the relation between perceived value of the EHR, the degree of participation in the implementation process, and the resulting quality of EHR systems was investigated. The value that end users expect is not achieved within Dutch hospitals. It was found that no hospital had so far reached third generation EHR functionality, even though several hospitals are actively pursuing it. Innovation with respect to EHR systems in hospitals is limited because of a lack of capabilities, not because of a lack of participation. Extensive and ill-targeted end user involvement tends to delay decision making and exacerbates the mismatch between implementation goals and results. Quality issues focus on information quality in terms of completeness and system quality in terms of reliability. This study contributes in combining participation models with the technology acceptance model and the IS success models. Electronic Health Records can be evaluated with this combination and a prescriptive analysis has lead to practical advice to the Dutch Ministry of Health.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"125 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":"124200546","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 management of the oil companies is generally aware of the increasing risks associated with the transition, but so far, investment in incident response (IR) capability has not been highly prioritized because of uncertainty related to risks and the present reactive mental model for security risk management. In this paper, we extend previous system dynamics models on operation transition and change of vulnerability, investigating the role of IR capability in controlling the severity of incidents. The model simulation shows that a reactive approach to security risk management might trap the organization in low IR capability and lead to severe incidents. With a long-term view, proactive investment in IR capability is of financial benefit.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"62 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120879963","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}

Theoretical and empirical research has typically attempted to explain such customer loyalty from the perspective of customer's satisfaction. However, although loyal customers are typically satisfied, satisfaction alone can be an unreliable predictor of loyalty. This research examines how switching costs can impact loyalty in a context where network effects may dominate. Additionally, the research measures how loyalty impacts customer willingness to pay (WTP) using a contingent valuation approach. The results reveal that switching costs do increase consumers' loyalty and WTP. For OPSS loyalty is a significant contributor to increased WTP. Implications for research and practice are discussed.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"40 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":"114538699","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}

However, little has been written on how these new loads will affect the medium and low-voltage distribution infrastructure. This paper briefly reviews the results of the existing PHEV studies and describes a new model: the PHEV distribution circuit impact model (PDCIM). PDCIM allows one to estimate the impact of an increasing number of PHEVs (or pure electric vehicles) on transformers and underground cables within a medium voltage distribution system. We describe the details of this model and results from its application to a distribution circuit in Vermont.","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":"121466222","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 fact has led some states (e.g., Maine) to incorporate macroinvertebrates in their water quality standards. To quantify the relationship between macroinvertebrates and urban land use, this study used data from the US Geological Survey \"Effects of Urbanization on Stream Ecosystems\" (EUSE) program. Bayesian networks were developed to characterize the relationship between urban land use metrics and selected macroinvertebrate taxa. It is shown that impervious surfaces and percent urban land have a strong effect on sensitive species of macroinvertebrates, demonstrating the adverse effect of urbanization and thus the value of these macroinvertebrate taxa as indicators of pollution. The resultant models are probabilistic and graphical, making them easily interpretable techniques for urban planning to achieve downstream water quality goals and sustain aquatic ecosystems.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"41 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":"114706876","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}

First, entrepreneurship in the digital economy entails three distinct, yet interrelated, types of opportunities: business, knowledge and institutional. The knowledge intensive and disruptive nature of IT requires entrepreneurs to engage in each form of entrepreneurial practice to create sustainable ventures. Second, entrepreneurial practices in the digital economy are inherently sociomaterial. Investigating these three forms of entrepreneurship jointly and the sociomaterial practices through which they are enacted provides a deeper understanding of the nature and dynamics of new venture discovery and exploitation. We illustrate these points with the example of an online dating service, eHarmony, to highlight how sociomaterial practices of business, knowledge, and institutional entrepreneurship are manifest and synergistic. We then outline a research agenda to develop these ideas.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"17 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":"127791707","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}

Having integrated and standardized data as well as processes reduces costs, improves collaboration and eases decision making for managers. Higher quality levels can be reached by successfully implemented standard processes. But due to the wide variety of business process types several challenges for the standardization of business processes exist. The diversity of business processes makes business process management (BPM) a cumbersome and complex challenge. Therefore, the main aim of this paper is to identify business process standardization success factors. As a first step, we use the categorization criteria offered by Lillrank as a starting point for our research and develop a theoretical research model of business process standardization success. Afterwards we conduct a preliminary test of our model in two case studies at two German companies.","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":"126210889","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}
