We present a formal solution to the problem of situation identification in learning of structural concepts. Structural concepts are characterized by the interrelationships and attributes of their parts, rather than by just their own direct attributes. Our solution extends the declarative approach to bias of (Russell and Grosof, 1987) by formalizing the beliefs about relevancy in a more complex ...

Appendix B of The Principles of Mathematics (1903) contains Russell’s first statement of his theory of logical types. This simple version of the theory is designed to block the reasoning that leads to the paradox of the Russell class. But Russell notes immediately that new problems arise. The problems culminate in the paradox of propositions. This is a problem that seems to run in exact paralle...

Russell body gastritis is a rare form of chronic gastritis. It is characterized by the invasion of lamina propria by plasma cells that included eosinophilic cytoplasmic inclusion. In the literature, most of the cases are associated with Helicobacter pylori. Russell body gastritis and Helicobacter pylori infection are generally seen together incidentally. We report here two cases of Russell body...

Frank Russell, 2nd Earl Russell (1865–1931), was a man of rational thought and social conscience who, released from his early imbroglios, embarked on controversial career, throwing name political weight behind range desperate but often successful causes. This bibliographical guide acknowledges labours, illustrates diversity demonstrates why deserves to be taken seriously.

Russell and Walker proposed different ways of constructing instants from events. As an explanation of “time as a continuum”, Thomason favoured Walker’s construction. The present paper shows that Russell’s construction fares as well. To this end, a mathematical characterization problem is solved which corresponds to the characterization problem that Thomason solved with regard to Walker’s constr...

The taxonomic status of the genus Ambengana Millidge & Russell-Smith, 1992, is revised on the basis of its original description, illustrations and re-examination of the type species. A new synonymy is proposed: Ambengana complexipalpis Millidge & Russell-Smith, 1992 (the type species of Ambengana) syn. n. with Neriene birmanica (Thorell, 1887). Therefore,the genus Ambengana Millidge & Russell-S...
