Our study extends on past research by examining how culture and fusion with one's culture influences helping behavior (help request and help given) when interacting with a cooperative versus non-cooperative counterpart. Canadian, Chinese and Indian participants engaged in an intracultural dyadic interaction using a virtual decision making game, FireSim, where they had to protect their village and its assets from seasonal fires with the option of requesting help and/or providing help to a neighboring village (counterpart). The results illustrate that Canadians (individualists) were less influenced by the situation, as their helping behavior was not significantly affected by partner's helping behavior, compared to Chinese and Indian individuals (collectivists). Moreover, Canadians were less likely to request for help but overall received more help compared to individuals from collectivistic cultures. We also found that the more a person was fused with his or her culture, the more likely that individual would provide help, if partner was cooperative. Potential implications and further research for inter-cultural helping behavior is discussed.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"62 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":"128567947","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}

It provides them with information processing capabilities to enable computers to sense, integrate, present, and react to all aspects of the physical world. This move from “interconnected computers” to “interconnected things” requires simplifying the development of new applications and services by supporting interoperability among heterogeneous devices; so that the programmer can focus on the development of applications enabled by the infrastructure of IoT. Middleware is a software layer interposed between the infrastructure and the applications using it [1] that basically aims to support important requirements for these applications.

In this project, an extension is proposed to the concept of distributed VCS through the development of a specialized distributed file system. In order to reduce the use of bandwidth and disk space usually required by a local copy of a distributed VCS repository, a new approach is proposed in which only essential files are initially retrieved, while other files are downloaded as they are needed. This strategy can be useful in devices where bandwidth, storage and power resources are limited and/or expensive, such as tablets or smartphones.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"1 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":"130396200","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 deal with the important consequences (human and economic losses) of these situations, we study how to represent emergency management situations based on experience feedback. We use several techniques: situations representations, knowledge engineering techniques and scenarios definition. Several dimensions are considered in this study: organization, communication and problem solving activities. We present in this paper our first results related to the representation of a specific type of crisis management: a road accident. Our first concern is to define the structures and interface in order to handle experience of crisis management. This creates the necessary foundation to help the actors to make decisions during the management of crisis.

Cognitive Radio(CR) network offers a promising solution to improve spectrum utilization and efficiency by harnessing the available spectrum resources in real-time. However, participants in the CR network can comprise of malicious adversaries who adopt dishonest and non-cooperative strategies to attack the network. In our research, we focus on a critical attack on the CR network: Primary User Emulation (PUE). In a PUE attack, the malicious adversary violates spectrum sharing etiquette by impersonating the primary user at the expense of other unselfish secondary users. To thwart such an attack, we present a strategy to authenticate the primary user, which involves collaborative learning among CR users.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"1 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":"131337168","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}

Whether for sharing images, sharing videos, or even sharing live gaming sessions, such applications must deal with session sizes from tens to tens of thousands of people. However, existing products have not been able to provide a scalable cloud-based system that synchronizes disparate web content among many users. Such a goal is desired in order to provide the benefits of cloud deployments to collaborative applications. Many such applications cannot predict the number of connections which they may need to handle. As such, applications must either provision a higher number of servers in anticipation of more traffic, or be faced with a degradation of the user experience when a large number of clients connect to the application. Cloud-based deployments can alleviate these issues by allowing the application's server base to scale automatically with user demand. A cloud deployment can also distribute servers throughout different geographic locations in order to offer improved latency and response times to its clients. This paper will present an architecture for a distributed, collaborative, and server-based application. The application is deployed inside a distributed cloud environment, which consists of multiple clouds in various geographic locations.","PeriodicalId":200122,"journal":{"name":"2012 International Conference on Collaboration Technologies and Systems (CTS)","volume":"27 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":"117129120","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}
