Drawing Boundaries

In “On Drawing Lines on a Map” (1995), I suggested that the different ways we have of drawing lines on maps open up a new perspective on ontology, resting on a distinction between two sorts of boundaries: fiat and bona fide. “Fiat” means, roughly: human-demarcation-induced. “Bona fide” means, again roughly: a boundary constituted by some real physical discontinuity. I presented a general typology of boundaries based on this opposition and showed how it generates a corresponding typology of the different sorts of objects which boundaries determine or demarcate. In this paper, I describe how the theory of fiat boundaries has evolved since 1995, how it has been applied in areas such as property law and political geography, and how it is being used in contemporary work in formal and applied ontology, especially within the framework of Basic Formal Ontology

All at sea in a barbed wire canoe: Professor Cohen's transatlantic voyage in IPE

The following article is written as a sympathetic critique of Benjamin Cohen's recent identification in RIPE of incommensurable traditions of American and British IPE. It is also designed to engender further debate within the subject field on this most central of issues. Our argument is that scholars should beware the rigid terms in which Cohen identifies IPE's transatlantic divide, because simply by naming his two camps as polar opposites the invitation is open to others to entrench such an opposition in their own work. This would be regrettable enough had IPE already lapsed into the geographical division that Cohen describes. It is made more regrettable still by the fact that this is in any case an inaccurate account of the field which serves to marginalise much of the work that is currently at its cutting edge

A unified framework for building ontological theories with application and testing in the field of clinical trials

The objective of this research programme is to contribute to the establishment of the emerging science of Formal Ontology in Information Systems via a collaborative project involving researchers from a range of disciplines including philosophy, logic, computer science, linguistics, and the medical sciences. The re­searchers will work together on the construction of a unified formal ontology, which means: a general framework for the construction of ontological theories in specific domains. The framework will be constructed using the axiomatic-deductive method of modern formal ontology. It will be tested via a series of applications relating to on-going work in Leipzig on medical taxonomies and data dictionaries in the context of clinical trials. This will lead to the production of a domain-specific ontology which is designed to serve as a basis for applications in the medical field

Cognitive and Identitarian Aspects in Jean Rhys’ Fiction

From Gnỗthi seautόn (‘Know Thyself’) to cognitive theories of the self there has been a long time, but the paradigm has almost remained the same. This article proposes a reconsideration of their rediscovery filtered through Jean Rhys’ post-colonial sensitivity. Between the ‘core self’ and its iridescent, exotic edges, broadly speaking, the thoroughly analyzed facets of cultural identity interpose

An Introduction to Ontology

Analytical philosophy of the last one hundred years has been heavily influenced by a doctrine to the effect that one can arrive at a correct ontology by paying attention to certain superficial (syntactic) features of first-order predicate logic as conceived by Frege and Russell. More specifically, it is a doctrine to the effect that the key to the ontological structure of reality is captured syntactically in the ‘Fa’ (or, in more sophisticated versions, in the ‘Rab’) of first-order logic, where ‘F’ stands for what is general in reality and ‘a’ for what is individual. Hence “f(a)ntology”. Because predicate logic has exactly two syntactically different kinds of referring expressions—‘F’, ‘G’, ‘R’, etc., and ‘a’, ‘b’, ‘c’, etc.—so reality must consist of exactly two correspondingly different kinds of entity: the general (properties, concepts) and the particular (things, objects), the relation between these two kinds of entity being revealed in the predicate-argument structure of atomic formulas in first-order logic

Using conceptual metaphor and functional grammar to explore how language used in physics affects student learning

This paper introduces a theory about the role of language in learning physics. The theory is developed in the context of physics students' and physicists' talking and writing about the subject of quantum mechanics. We found that physicists' language encodes different varieties of analogical models through the use of grammar and conceptual metaphor. We hypothesize that students categorize concepts into ontological categories based on the grammatical structure of physicists' language. We also hypothesize that students over-extend and misapply conceptual metaphors in physicists' speech and writing. Using our theory, we will show how, in some cases, we can explain student difficulties in quantum mechanics as difficulties with language.Comment: Accepted for publication in Phys. Rev. ST:PE

Geopolitics at the margins? Reconsidering genealogies of critical geopolitics

Critical geopolitics has become one of the most vibrant parts of political geography. However it remains a particularly western way of knowing which has been much less attentive to other traditions of thinking. This paper engages with Pan-Africanism, and specifically the vision of the architect of post-colonial Tanzania, Julius Nyerere, to explore this overlooked contribution to critical engagements with geopoli- tics. Pan-Africanism sought to forge alternative post-colonial worlds to the binary geopolitics of the Cold War and the geopolitical economy of neo-colonialism. The academic division of labour has meant that these ideas have been consigned to African studies rather than being drawn into wider debates around the definitions of key disciplinary concepts. However Nyerere’s continental thinking can be seen as a form of geopolitical imagination that challenges dominant neo-realist projections, and which still has much to offer contemporary political geography

Toward user oriented semantic geographical information systems

User Oriented Geographical Information Systems, a recent adaptation of classical GIS concepts to everyday usage, are becoming more and more present in the web landscape. Recent developments show the need of adding higher semantic levels to the existing frameworks, to improve their usage, as well as to ease scalability. We point out limits of actual examples, related to handling heterogeneous data, scalability issues, and expressiveness, and suggest a framework for building a Semantic User Oriented GIS. Notably this framework aims to address the peculiarities of the geographical space domain, and to offer a cognitively sound interface to the user
