For example, what information is key to the capabilities of an insurgent network, which has the information and how is it communicated to the others within and without the network. The same analysis can be applied to the FEMA and other emergency response networks established in the aftermath of events such as Hurricane Katrina and 9/11 where there was a need to understand what information was available, how it could be communicated and what the effect of proposed changes would be across the networks. This paper describes a dependency based network model which allows the explicit modeling of information/knowledge content, the conduits through which information passes, and the impact on the inter-dependent network of people, organizations, locations, resources and concepts if the content or the conduits are modified. The dependency model handles both quantitative and qualitative node outputs enabling it to identify the key dependent nodes and information content within the network. This analysis allows the development of Plan Models which capture the changes required in the network to bring about desired effects. Plan Models identify the mechanisms and/or resources that should be used to bring about the desired effects either directly by affecting a node outputs or indirectly by affecting the outputs of the nodes they are dependent upon. An example taken from a counter insurgency scenario is used to illustrate the benefits of the approach and range and scope of its applicability.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116219981","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 gap between behavioral theory and field practice partly explains why interfaces have not achieved this goal. In this paper, we describe a research program on human centered interactive interface design that bridges this gap with consumer based investigation of two energy reduction interfaces: Kidogo and Powerbar. Kidogo allows users to donate savings from energy conservation to public goods. In the first study, which examines Kidogo components, we investigate how alternative beneficiaries help users to connect emotionally with saving energy. In our second study, comparing Kidogo and Powerbar interventions, we investigate the ability of affectively and cognitively framed interfaces to persuade individuals to perform conservation behaviors. The first study suggests that interfaces should use negative valence images to establish an emotional connection, and the second provides evidence that affectively framed interfaces promote willingness to perform conservation behaviors.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127139299","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}

Most of the teams that we collaborate with work identically to the way they did in the past, without using effective collaborative tools to share their knowledge with their peers. Collaboration is usually an afterthought, and is often handled in an awkward setting. We believe the best way to introduce collaboration into areas that are resistant by nature is to embed into low level and hidden system components so that scientists collaborate without consciously putting in extra efforts. Based on this hypothesis, this paper presents our work in creating a collaborative system, which allows a diverse set of scientists to work together efficiently. Two of the main aspects of our system are in our use of provenance to associate files and its associated metadata with the information that domain experts are interested in, and an easy-to-use high-performance I/O system which automatically annotates the output file(s) with a unified schema. To accomplish our goals, we leverage an existing I/O framework, ADIOS and an existing web interface, eSiMon, and add new techniques and mechanism to efficiently bring together computation and visualization.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131911376","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 promote the elastic nature of cloud platform but force upon significant challenges to cloud service providers. Particularly, security issues such as inconsistency may arise while dynamic changes such as virtual machine migration occur. In this paper, we propose a formal framework for the specification of virtual machines migration and security policies updates. This framework enables us to verify that the global security policy after the migration is consistently preserved with respect to the initial one. To this end, we define a new calculus, namely cloud calculus that can be used to specify the topology of a cloud computing system and firewall security rules. It also enables specifying the virtual machines migration along with their security policies. The semantics of our calculus is based on structural congruence and a reduction relation. In order to verify the global security policy within the new configuration, we define a testing equivalence over cloud terms. Finally, we provide an illustrative case study to demonstrate the applicability of our approach.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115361147","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}
