Not only does Intel's IT group keep Intel's business operations running, it also contributes to Intel's business transformation via user experience research and architecture path finding for leading edge technologies. IT sees social computing as a strategic way to improve collaboration, foster innovation, and facilitate learning. Our research has identified the best opportunities for using social computing and other technologies to boost collaboration and productivity across Intel. To keep achieving maximum benefit from its collaboration efforts, Intel IT continues to invest in social capabilities and also partners with Intel HR to help address cultural and motivational barriers. Beyond improving personal productivity, we are looking to enable efficiency in Intel's business divisions for product design, manufacturing, and sales, through the use of cutting-edge social technologies, including social analytics, immersive video/sketching, federated identity and access management, and cross system activity stream aggregation. Our goal is to continue to transform collaboration across Intel into a seamless and unified experience that brings together relevant information, people, and business intelligence to fully support employee and business workflows.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131835713","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}

{"title":"Team structure and quality improvement in collaborative environments","authors":"N. Manukyan, M. Eppstein, J. Horbar","doi":"10.1109/CTS.2013.6567282","DOIUrl":"https://doi.org/10.1109/CTS.2013.6567282","url":null,"abstract":"Teams comprising diverse individuals have been shown to increase the collective creativity in jointly solving problems. However, in contexts where the purpose of collaboration is knowledge diffusion in complex environments, it is not clear whether team diversity will help or hinder effective learning. For example, in organized quality improvement collaboratives (QICs), healthcare institutions exchange information on clinical practices and outcomes with the aim of improving health outcomes at their own institutions. However, what works in one hospital may not work in others with different local contexts, due to non-linear interactions among various treatments and practices. While there is limited evidence that some QICs have resulted in improved care, it is not yet clear what factors contribute to the effectiveness of these team collaborations. In this study, we use an agent-based model to study how different strategies of team formation, including team diversity and size, affect quality improvement in simulated collaborative environments. We show that, in this context, teams comprising similar individuals outperform those with more diverse teams, and that this advantage increases with the complexity of the landscape and level of noise in assessing fitness. Furthermore, we show that larger teams of relatively homogeneous agents perform better than smaller teams, and that effective learning through team collaborations is dependent on the level of knowledge of team members' performance levels. Thus, our results suggest that groups of similar hospitals should collaborate as a single team and openly share detailed information regarding their clinical practices and outcomes. To facilitate this, we propose a virtual collaboration framework that would allow hospitals to efficiently identify potentially better practices in use at other institutions similar to theirs, without any institutions having to sacrifice the privacy of their own data. Our results may also have implications for other types of data-driven diffusive learning, such as in personalized medicine.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133698770","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}

Currently, patches are periodically released to countermeasure trust issues that arise in e-commerce communities. In this paper, we propose a methodology for designing trustworthy applications that enables an application designer to model applications resilient to trust related threats early in the development life cycle. Such modeling requires understanding of the system data flow and how the different processes use the system data. Our methodology consists of two phases, namely, data flow trust model and trust mitigation model.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115385863","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 paper proposes a reference NORA problem that is representative of real problems, and can rationally scale to very large sizes. It then develops a highly concurrent implementation that can run on large systems. Each step of this implementation is sized in terms of how much of four different resources (CPU, memory, disk, and network) might be used. From this, a parameterized model projecting both execution time and utilizations is used to identify the “tall poles” in performance. The parameters are then modified to represent several different target systems, from a large cluster typical of today to variations in an advanced architecture where processing has been moved into memory. A “thought experiment” then uses this model to discover the parameters of a system that would provide both a near 100X speedup, but with a balanced design where no resource is badly over or under utilized.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115807039","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 key technology enables a wide range of potential applications and services including monitoring of physical environments, enhanced industrial control, surveillance, remote health care and logistics. Real-time monitoring of water pipeline network is one such application where WSN plays significant role. The issue of water is considered to be one of the largest and most serious challenges. It is expected to aggravate over time, given the scarcity of available traditional water resources and the massive costs of providing fresh potable water from non-traditional sources such as desalination plants. Therefore, a robust and reliable WSN technique is required to monitor leaks, bursts and other anomalies in the water pipeline systems. This paper presents a consolidated review on WSN for water pipeline monitoring applications.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124147106","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 context the collaboration among the different components is a crucial aspect, but not always it can be enacted in a direct way, i.e., by means of direct communication between components. This is because of the simplicity of the robots, but this turns out to increase robustness and flexibility of the swarm systems. In this paper we present a case study in which some robots are in charge of sweeping the perimeter of an area, and propose a distributed algorithm for the task division. We have tested the proposed algorithm in different situations; we report the results and we also compare them to the ones achieved with no collaboration.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121667929","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 that end, we systematically analyzed two sets of data: academic publications on collaborative games and reviews of commercial collaborative games. From this examination, we acknowledge the important relationship between games and the cultural context, and we identify three main areas of study for this type of games (learning environments, interaction, and in-gameplay experience), which serve as a landscape for the investigation on collaborative and cooperative games.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123589529","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 project at the University of Nevada, Reno dubbed the Nevada Climate Change Portal is currently being developed to assist in providing climate data and data services to researchers. One part of this portal is being developed to enable users to define scientific workflows and then run them. It is in this particular functionality of the Nevada Climate Change Portal in which the topic of this paper resides. This paper is concerned with the creation of a web-service based workflow job manager to present information more graphically than the typical text-based job manager. Modern software technologies such as .Net, Silverlight, WSDL, SOAP, and Graphviz are used to develop the features of this software. Aside from the gross technical details, the proposed job manager contains a way to represent the current progression status of a simulation in a graphical form and it is hoped that this will allow the adaption of the GUI to a wider variety of platforms such as smart phones or tablet computers. Increasing the availability of the job manager to different platforms is expected to allow users to collaborate in a more convenient manner, because they no longer need to use a PC with a large display in order to view the status of their running jobs.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116598275","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}
