Semantic theories, linguistic essences, and knowledge of meaning

This paper argues, first, that the information problem poses a foundational challenge to mainstream semantics. It proposes, second, to address this problem by drawing on notions from Kit Fine’s essentialist framework. More specifically, it claims that the information problem can be avoided by strengthening standard truth theories, employing an operator expressing the notion of a relative constitutive semantic requirement. As a result, the paper proposes to construe semantic theories as theories of semantic requirements, and semantic knowledge as knowledge of such requirements.

Family ownership, information problem and firm performance

This paper reviews recent corporate financial literature dealing with family business issues. It discusses research papers that explain the nature and type of agency problems in family firms. It provides empirical evidence of the association of family ownership with information asymmetry. It also portrays the influence of family firms over corporate disclosures. We have analyzed literature to explain the empirical association between family ownership, and so ownership control, and firm performances. This paper also attempts to find out the research gap based on reviewed papers and tries to give the future directions of research in this regard.

Global symmetry, Euclidean gravity, and the black hole information problem

In this paper we argue for a close connection between the non-existence of global symmetries in quantum gravity and a unitary resolution of the black hole information problem. In particular we show how the essential ingredients of recent calculations of the Page curve of an evaporating black hole can be used to generalize a recent argument against global symmetries beyond the AdS/CFT correspondence to more realistic theories of quantum gravity. We also give several low-dimensional examples of quantum gravity theories which do not have a unitary resolution of the black hole information problem in the usual sense, and which therefore can and do have global symmetries. Motivated by this discussion, we conjecture that in a certain sense Euclidean quantum gravity is equivalent to holography.

Revealing Thinking: Teachers Working Together on Information Literacy

Collaboration between library and teaching staff on single projects often goes well, but does not always lead to sustained collaboration or independent teaching in support of information literacy. Where teachers' understanding of information problem solving processes is under-- developed and library media support is not available, multiple approaches to professional development are essential if teachers and children are to be empowered as information problem solvers. This paper presents and discusses two research initiatives in elementary schools in terms of factors influencing the path of professional development and sustained attention to information literacy. One has information problem solving as the primary focus whereas the second centres on teachers as learners and information problem solvers in their own right.
