The concept of Business Activity Monitoring (BAM) refers to the observation, analysis, and presentation of real-time information about business activities across systems' and companies' borders. Designing and maintaining BAM applications is challenging, as the involved concepts (e.g., business processes, audit logs, performance measures) --though being strongly interrelated-- are developed by different communities of practice. Also, they reside on different levels of abstraction, and are handled by different IT systems. Hence, we developed a conceptual modeling language which extends the widely accepted Business Process Modeling Notation (BPMN) by BAM-relevant concepts. The main results presented in this paper are: (1) a meta-model which formally describes the conceptual aspects of the developed BPMN extension (abstract syntax); (2) graphical symbols as an exemplary representation of this abstract syntax (concrete syntax); (3) a demo scenario that illustrates the application of the language in a fictitious scenario.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"14 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":"127257353","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 enable a new way to connect globally dispersed employees to jointly contribute to the company's innovation process. To explore the potential and current usage of virtual worlds as collaborative innovation platforms, we conducted a qualitative study at IBM. We interviewed IBM employees belonging to a special work group called \"Web 2.0/virtual worlds\" in order to gain experience in generating and exchanging knowledge, ideas and insights by virtually collaborating and interacting in SL. Our results show that SL bears the potential to connect organizational members as it provides media richness and facilitates social interaction. However, current virtual worlds still capture some problems. Improvements including platform stability, user interface, or security issues may be necessary to use virtual worlds more effectively and efficiently to improve the company's innovation process.","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":"127361897","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}

Especially simultaneous charging at home may lead to significant load spikes or grid stability issues. Prior research has identified the need for appropriate coordination approaches. This research focuses mostly on coordinating system loads ignoring local grid constraints. The suggested mechanisms either are centralized control approaches ignoring user preferences or based on the electrical energy cost. We propose to complement these approaches by using mechanisms from revenue management for perishable assets. First, we formalize charging coordination as a minimal revenue management problem and then derive an appropriate advance sale mechanism. By accounting for heterogeneous customer segments, this approach can achieve a socially efficient allocation of available charging capacity. Using a local neighborhood scenario, we evaluate the impact of such an approach.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"15 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":"125495340","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 Demand Response Spinning Reserve project has demonstrated that it is technologically feasible to provide spinning reserves using aggregations of small, controllable residential appliances. This paper addresses two concerns stemming from the high cost of real-time telemetry, which makes it impractical to monitor individual, small appliances comprising an aggregated demand-response resource. First, time-stamped information taken at each stage in a load curtailment sequence, starting with the grid operator's initial dispatch command and ending with the receipt of the command by the residential appliances, is analyzed to measure the speed of demand response. Second, load information from distribution feeders serving aggregations of controlled appliances along with end-use monitoring information collected from a sample of the appliances are analyzed to estimate and understand the influencing the magnitude and statistical significance of the amount of load curtailed.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"19 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":"126927281","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 better understand the effectiveness of rewards, this study examines the relative effect of extrinsic and intrinsic rewards. Further, noting that extrinsic rewards have been observed to have inconsistent effects, this study investigates whether the effect of extrinsic rewards is contingent upon job design. Results of a survey of 163 employees show that extrinsic rewards have a weaker effect than intrinsic rewards but its effect can be enhanced by increasing job autonomy, skill variety, and task identity. This study contributes to research by identifying the circumstances in which extrinsic rewards have stronger effect and offers practical suggestions for providing rewards and designing jobs to promote knowledge contribution by employees in organizations.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"38 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":"115076301","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}

Emerging information technologies provide us with opportunities to answer a long-standing challenge in citizen engineering -- can we effectively extract reliable results from a myriad of crowd inputs of varying quality? To investigate efficient approaches to achieving this \"wisdom of crowds\", we established a prototype site, where 242 students, acting as surrogate citizen engineers, signed up, logged in, and performed engineering tasks -- tagging photographs of earth-quake damage. Based on the analysis of user online behaviors, we developed an operable data mining algorithm to retrieve highly trustworthy results from thousands of limited size submissions collected from a cohort of contributors. By converging weight assignments and crowd consensus step- by-step, this extraction algorithm improves the quality of the results over time.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"27 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":"115494918","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}

Its mission is to advance exposure biology research by developing new methods of physical activity data capture and analysis from a geospatial perspective. A key early insight was that while exposure biology investigators often employ their own data analysis frameworks, many frameworks are conceptually similar. Forming a community based on common requirements and research directions, and serving that community with a common computing framework would, itself, be a major contribution to the NIH mission. This paper describes the PALMS Cyber infrastructure (CI), which comprises both the PALMS computing services and the exposure biology community it serves. By leveraging state of the art software architecture techniques, the PALMS CI is well positioned to serve the co evolution of a thriving research community and the computing systems that support it.","PeriodicalId":380801,"journal":{"name":"2012 45th Hawaii International Conference on System Sciences","volume":"90 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":"115559249","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}
