Software agent-based negotiation is a major method to automate the interactions in electronic marketplaces and Internet enabled communities. The traditional approach is to let the agents to interact directly. In this paper it has been investigated how a mediator agent can improve the chances to reach the agreement via bargaining. Although the ideal mathematical model was proposed in the seventi...

In this paper we present a system for data integration on the web, where an XML-based mediator plays a key role providing a homogeneous view of different data sources. One novelty of our approach is that we also propose solutions for the problems of generation and maintenance of mediators. Observe that, in dynamic environments, such as the Web, individual data sources may change not only their ...

according to studies, self-esteem plays an important role in mental health. self-esteem is also one of the most important correlates of anxiety, especially social anxiety. being anxiety in adolescents make negative impacts on their academic performance, mental health and social function. this study aims to investigate the relationship between self-esteem and mental health, according to the medi...

mental health in adolescents is influenced by several factors. body image is one of the factors in predicting mental health. moreover, it affects social communication and creates the social anxiety. the present study is cross-sectional and correlational. the statistical population is the guidance and high school students in shiraz in 2013-2014 that 180 students include 101 girls and 79 boys wer...

Query rewriting method is proposed for the heterogeneous information integration infrastructure formed by the subject mediator environment. Local as View (LAV) approach treating schemas exported by sources as materialized views over virtual classes of the mediator is considered as the basis for the subject mediation infrastructure. In spite of significant progress of query rewriting with views,...

We present the information mediator prototype called Kind [GLM00], recently developed as part of an integrated Neuroscience workbench project at SDSC/UCSD within the NPACI project. The broad goal of the workbench is to serve as an environment where, among other tasks, the Neuroscientist can query a mediator to retrieve information from across a number of information sources, and use the results...

Mediator is a multiprotein transcriptional co-regulator complex composed of four modules; Head, Middle, Tail, and Kinase. It conveys signals from promoter-bound transcriptional regulators to RNA polymerase II and thus plays an essential role in eukaryotic gene regulation. We describe subunit localization and activities of Mediator in Arabidopsis through metabolome and transcriptome analyses fro...
