Outsourcing, the passing on of tasks by organizations to other organizations, often including the personnel and means to perform these tasks, has become an important IT-business strategy over the past decades. We investigate imaginative definitions for outsourcing relations and outsourcing transformations. Abstract models of an extreme and unrealistic simplicity are considered in order to inves...

Conceptual authoring support enables authors to model the content of their documents, giving them both constructive and analytical aid. One key aspect of the constructive aid are schemata that contain proven structures that the author may instantiate in her document. This paper presents operations offered in an authoring system partially derived from extended schema definitions. The author may ...

We consider some flat space theories for spin 2 gravitons, with less invariance than full diffeomorphisms. For the massless case, classical stability and absence of ghosts require invariance under transverse diffeomorphisms (TDiff), hμν 7→ hμν + 2∂(νξμ), with ∂μξ μ = 0. Generic TDiff invariant theories contain a propagating scalar, which disappears if the symmetry is enhanced in one of two ways...

In his pioneering work Mostowski (1957) made the very insightful suggestion that quantifiers are special higher order relations, relations between relations (where sets are unary relations). This move led eventually to the generalised quantifier theory (GQT). In particular it made it possible to study ”classical” quantifiers using familiar tools of the elementary theory of relations. This simpl...

The scaling form of the free–energy near a critical point allows for the definition of various universal ratios of thermodynamical amplitudes. Together with the critical exponents they characterize the universality classes and may be useful experimental quantities. We show how these universal quantities can be computed for a particular class of universality by using several Quantum Field Theory...

We consider the universality class of the two-dimensional tricritical Ising model. The scaling form of the free energy leads to the definition of universal ratios of critical amplitudes which may have experimental relevance. We compute these universal ratios by a combined use of results coming from perturbed conformal field theory, integrable quantum field theory, and numerical methods.

Traditionally, grammaticalisation has been described as being based on language-specific phenomena such as metaphorical extension or reanalysis. This characterisation is somewhat in contrast to claims that grammaticalisation is involved in the much more general process of the initial emergence of language. In this article, we provide a unified analysis of both the metaphor-based and the reanaly...

In this paper we make use of some of the conceptual tools provided by Cognitive Linguistics in order to discuss the issue of knowledge organization. We start off from the account provided by Ruiz de Mendoza (1996), who fleshes out the key ideas of the network organization model postulated by Langacker (1987). In Ruiz de Mendoza’s account a semantic characterization consists of what he terms a g...

PURPOSE The aim of this paper is to position, define and discuss three concepts crucial for research and practice concerning person-environment relationships, viz. accessibility, usability and universal design. METHODS Literature review, synthesized with the authors' research and practice experiences. RESULTS The authors suggest an instrumental, three-step definition to accessibility, highl...
