bezoar, an illness known for a long time is nowadays the subject of renewed interest. this is due to the fact that it may occur as a complication of the gastric operations now used with increasing frequency. a case of phytobezoar after vagotomy and pyloroplasty for peptic ulcer is reported. the patient recovered with normal medical treatment. codifying the etiology, pathogeny and treatment has ...

The paper presents an initial explorations on T, I, F operations based on genetic concept hierarchy and genetic referential hierarchy, as a novel proposal to the indeterminacy issue in neutrosophic logic, in contrast to the T, I, F values inherited from conventional logics in which those values would fail to demonstrate the genetic aspect of a concept and accordingly loose the connection betwee...

This paper describes the interaction and object representation features of the visual database editor ESCHER which is based on the nested relational data model. In particular we like to indicate the multiple two-dimensional cursors and their way of moving in and out of nested objects, cut-and-paste operations, the QBE-like query mechanism, interactive schema design, and the unusual, self-refere...

Many relational and object-oriented database systems provide referential integrity and compotmd operations on related objects using relationship mechanisms. Distributed object systems are emerging to support applications that access objects across distributed, heterogeneous system boundaries. Because the fundamental assump tions of distributed, heterogeneous, federated computing systems differ ...

Referential integrity underlies the relational representation of objeceoriented structures. The concept of referential integrity in relational databases is hindered by the confusion surrounding both the concept itself and its implementation by relational database management systems (RDBMS). Most of this confusion is caused by the diversity of relational representations for object-oriented struc...

The paper introduces the principles of object-oriented translation for target machine which provides executing the sequences of elementary operations on persistent data presented as a set of relations (programmable relational system). The language of this target machine bases on formal operations of relational data model. An approach is given to convert both the description of complex object-or...

Referential thinking is the tendency to view innocuous stimuli as having a specific meaning for the self and is associated with personality traits and disorders. In three studies, this research examined the relations among referential thinking, self-processing, and paranoia. In study 1, follow-up questions on the Referential Thinking Scale (Lenzenweger, Bennett, & Lilenfeld, 1997) revealed that...

Referential integrity, which guarantees that named resources can be accessed when referenced, is an important property for reliability and security. In distributed systems, however, the attempt to provide referential integrity can itself lead to security vulnerabilities that are not currently well understood. This paper identifies three kinds of referential security vulnerabilities related to t...

Language learners must learn the meanings of many thousands of words, despite those words occurring in complex environments in which infinitely many meanings might be inferred by the learner as a word's true meaning. This problem of infinite referential uncertainty is often attributed to Willard Van Orman Quine. We provide a mathematical formalisation of an ideal cross-situational learner attem...

This is a paper to the panel “Conceptualizing the workpractice context of IS” at the ALOIS*2006 conference. It is a position statement concerning workpractice theory as a practical theory. Practice theory is concerned with workpractices and as such an example of “referential pragmatism”. A practical theory intends to be of value to practices and such a theory is seen as an example of “functiona...
