We found, that handling IT solutions is complex which results in several challenges that confront decision makers by developing IT solutions, such as the adaption of IT solution components to each other, or the integration to the customer's environment. To overcome these challenges, we propose a simulation model for prioritizing IT solution developments. The proposed model combines system dynamics and fuzzy logic and is based on a decision framework, which we derive from a broad literature review. To show the model applicability, we apply it by a mid-sized German company. The simulation results show the priority ranking of IT solution developments. Based on these results decision makers are able to determine the developing and integrating sequence of IT solutions.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114880054","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}

Virtual worlds seem to be promising in means of support customer integration because of their three-dimensional environments, their ability to support immersion, and their advanced approaches of communication and collaboration. However, until now very little research exists about how to adapt virtual worlds to this field. In our contribution, we analyze different types of virtual worlds and identify their specific characteristics and abilities to support virtual customer integration.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127631663","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}

What happens however when users take the role of the researchers, and with some basic HCI training, design and conduct their own evaluation of a digital library? For several years, teams of students in master's level HCI classes at Drexel University were given the assignment of designing and carrying out heuristic evaluations of the interface of the Internet Public Library. Their final evaluation reports regularly focused on what, to a usability expert, would not be considered interface issues, such as problems with finding resources in the library. These outcomes contrasted with those of a parallel evaluation of the IPL carried out by doctoral students with a background in HCI, which found interface issues to be the main concerns. A post hoc comparison and analysis of these evaluations highlights differences between users' and evaluators' perceptions of usability, and has implications for the design of digital library evaluation and the roles of users and evaluators in such evaluation.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125451438","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}

Specifically, we analyze the popular entropy-based anomaly detection in detecting covert channels in Voice over IP (VoIP) traffic. There has been little effort in prior research to rigorously analyze how the knobs of anomaly detection methodology should be tuned. Such analysis is, however, critical before such methods can be deployed by a practitioner. We develop a probabilistic model to explain the effects of the tuning of the knobs on the rate of false positives and false negatives. We then study the observations produced by our model analytically as well as empirically. We examine the knobs of window length and detection threshold. Our results show how the knobs should be set for achieving high rate of detection, while maintaining a low rate of false positives. We also show how the throughput of the covert channel (the magnitude of the anomaly) affects the rate of detection, thereby allowing a practitioner to be aware of the capabilities of the methodology.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121936508","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}

Despite the ubiquity of such communities, there is limited theoretical and empirical research on how taking on a different identity is associated with one's contributive behavior in those communities. Drawing on the social psychology literature, we adopt the concept of self-discrepancy rooted in self-identity and derive an index for self-discrepancy by using the differences between actual and virtual self-identities. Next, we link the self-discrepancy with perceived privacy rights and with the quality and quantity of contribution. An analysis of 299 respondents showed that self-discrepancy significantly influenced perceived privacy rights and indirectly reduced quality and quantity of contribution in virtual communities. Furthermore, sub-group analysis revealed that the effects of self-discrepancy varied depending on whether the virtual community was utilitarian or hedonic.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122215679","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}

Visual feedback plays the role of a gentle moderator encouraging a speaker to yield the floor. To better evaluate the effect of visual feedback on collaboration, we purposefully distorted the apparent balance in the Conversation Clock, a shared visualization of conversation. We present a pilot study examining various distortion strategies followed by a more in depth study applying distortion to discussion. Our results indicate that participants will accept some significantly distorted visualizations as an accurate representation of conversation, however, distorted feedback provides only minimal impact on conversational balance. These findings suggest the mechanism in visualization that drives individuals towards balanced conversation is not solely influenced by the visual feedback and remains an open question for future work.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115856584","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 side effect of the growing number of platforms is the potential for incompatibilities among Action Centers that can reduce interoperability, knowledge sharing and reuse. We present an ontology for Action Center-oriented collaboration platforms that formalizes key concepts of the approach using OWL.

Characteristics from eighty total participants are tested across two different sessions. Performance is measured as a person's ability to modulate his/her mu rhythm. It appears that the version of software used in recording and interpreting EEGs, instrument playing, being on affective drugs, a person's sex, and age all play key roles in predicting mu rhythm modulation.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"320 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132301294","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 findings are that using socio-demographic segmentation bases yields modest useful information, whereas using attitudes as segmentation base is more informative. In the future, attention should be paid to understanding attitude selection better to yield even more relevant segmentations in the mobile services market, and to discovering whether combinations of different segmentation bases might be the most powerful base to do segmentation upon.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132359391","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}

As such, the acceptance of such technologies by healthcare professionals is an important topic of interest to both practitioners and researchers. IS acceptance has been widely researched in the extant literature, however, studies focusing on perspectives of healthcare professionals are sparsely represented. To add the growing work in this area, we used the unified theory of acceptance and use of technology (UTAUT) with a minor modification to examine the factors influencing IS acceptance among five healthcare professionals in Canada. A research model was developed and tested with data collected in a survey. Analyses of 227 healthcare professionals' data confirmed that their intentions to use IS and usage behaviors were significantly influenced by effort expectancy, social influence, compatibility, and organizational facilitating conditions. Performance expectancy did not yield meaningful interpretations. The study's implications for practice and research are discussed.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132367534","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}
