research findings suggest that the family context and communication patterns have high correlation with adolescent’s mental health indicators such as anxiety. therefore, the current study aimed to investigate the mediator role of coping strategies in relation between family communication patterns and students social anxiety. 140 students of shiraz guidance schools were studied they completed th...

This paper describes an active object-oriented mediator for the enforcement of global consistency between relational legacy databases. We discuss the problem of integrating several local relational systems into a federated system by the usage of an object-oriented mediator system. We explore how relational DBMSs can be enhanced to signal local updates that may violate global constraints without...

aim and background: schemas are cognitive patterns that have a major impact on the perception and behavior. therefore, it is necessary to investigate their role in determining and changing health related behaviors in ms patients. the purpose of this study is to investigate the mediating effect of illness perception on the relationship between early maladaptive schemas in the domain of rejection...

Decomposing a total causal effect into natural direct and indirect effects is central to revealing causal mechanisms. Conventional methods achieve the decomposition by specifying an outcome model as a linear function of the treatment, the mediator, and the observed covariates under identification assumptions including the assumption of no interaction between treatment and mediator. Recent stati...

A peer mediator system (PMS) is a decentralized mediator system based on the P2P paradigm, where mediators integrate data sources and other mediators through views defined in a multi-mediator query language. In a PMS mediator peers compose views in terms of views in other peers mediators and sources, or directly pose queries in the multi-mediator query language to some peer. All peers are fully...

The 26-subunit, 1.2 MDa human Mediator complex is essential for expression of perhaps all protein-coding genes. Activator binding triggers major structural shifts within Mediator, suggesting a straightforward means to spatially and temporally regulate Mediator activity. By using mass spectrometry (MudPIT) and other techniques, we have compared the subunit composition of Mediator in three differ...

Semantically relatedmediators form a hierarchical structure based on the definition of views in each mediator, since a view in a mediator is defined by views in other mediators or base tables in several local information servers. A global query is transformed into a set of its sub-queries; and, each subquery is the unit of evaluation in an information server or a child mediator. Therefore, it i...

The information needed by biologists and physicians for research purposes is distributed over many heterogeneous sources. Integration systems provide a single, centralized and homogeneous interface for users to query multiple information sources simultaneously. The major limitation of integration systems, including mediator-based systems, is that the tasks involved in their creation and mainten...
