Our work is part of the heterogeneous data integration, with the definition of a structural and semantic mediation model. Our aim is to propose architecture for the heterogeneous sources metadata mediation, represented by XML, RDF and RuleML models, providing to the user the metadata transparency. This, by including data structures, of natures fundamentally different, and allowing the decomposi...

The present study investigated how consequence value influences affect, attention, and learning while reading instructional texts, and if text difficulty moderates these effects. Participants studied four instructional texts on research methods in a 2 × 2 consequence value (high vs. low) × text difficulty (easy vs. difficult) within-subjects experiment. Consequence value was manipulated by assi...

In string compactification on a manifold X , in addition to the string scale and the normal scales of low-energy particle physics, there is a Kaluza-Klein scale 1 R associated with the size of X . We present an argument that generic string models with low-energy supersymmetry have, after moduli stabilization, bulk fields with masses which are parametrically lighter than 1 R . We discuss the imp...

Although cynical beliefs about human nature yield numerous adverse consequences for individuals’ life outcomes and well-being, very little is known about factors that counteract the development of cynical beliefs. Drawing from the literature on the “education effect” describing the importance of education in overcoming close-mindedness and negative views of others, we propose that education can...

The intermediator framework is required to support heterogeneous subject mediators interoperability in diverse world of mediation platforms that can be observed in distributed digital libraries and other areas. The intermediator framework based on the “local as view” mediation approach is introduced. The paper focuses on a protocol supporting registration of a mediator information (source) at a...

We identify the causal effect of trade-integration with China and Eastern Europe on voting in Germany from 1987 to 2009. Looking at the entire political spectrum, we find that only extreme-right parties respond significantly to trade integration. Their vote share increases with import competition and decreases with export access opportunities. We unpack mechanisms using reduced form evidence an...

Mediator systems federate and integrate data from disparate sources in order to elicit information that the individual sources cannot provide independently. The standard mediator architecture employs wrappers that translate heterogenous source data into a common (often semistructured) data model like XML. A “mediation engineer” provides an integrated view definition (IVD) on the wrapped XML sou...
