Fact, Fiction and Virtual Worlds

This paper considers the medium of videogames from a goodmanian standpoint. After some preliminary clarifications and definitions, I examine the ontological status of videogames. Against several existing accounts, I hold that what grounds their identity qua work types is code. The rest of the paper is dedicated to the epistemology of videogaming. Drawing on Nelson Goodman and Catherine Elgin's works, I suggest that the best model to defend videogame cognitivism appeals to the notion of understanding

Is resilience a normative concept?

In this paper, we engage with the question of the normative content of the resilience concept. The issues are approached in two consecutive steps. First, we proceed from a narrow construal of the resilience concept – as the ability of a system to absorb a disturbance – and show that under an analysis of normative concepts as evaluative concepts resilience comes out as descriptive. In the second part of the paper, we argue that (1) for systems of interest (primarily social systems or system with a social component) we seem to have options with respect to how they are described and (2) that this matters for what is to be taken as a sign of resilience as opposed to a sign of the lack of resilience for such systems. We discuss the implications of this for how the concept should be applied in practice and suggest that users of the resilience concept face a choice between versions of the concept that are either ontologically or normatively charged

Efficient Discovery of Ontology Functional Dependencies

Poor data quality has become a pervasive issue due to the increasing complexity and size of modern datasets. Constraint based data cleaning techniques rely on integrity constraints as a benchmark to identify and correct errors. Data values that do not satisfy the given set of constraints are flagged as dirty, and data updates are made to re-align the data and the constraints. However, many errors often require user input to resolve due to domain expertise defining specific terminology and relationships. For example, in pharmaceuticals, 'Advil' \emph{is-a} brand name for 'ibuprofen' that can be captured in a pharmaceutical ontology. While functional dependencies (FDs) have traditionally been used in existing data cleaning solutions to model syntactic equivalence, they are not able to model broader relationships (e.g., is-a) defined by an ontology. In this paper, we take a first step towards extending the set of data quality constraints used in data cleaning by defining and discovering \emph{Ontology Functional Dependencies} (OFDs). We lay out theoretical and practical foundations for OFDs, including a set of sound and complete axioms, and a linear inference procedure. We then develop effective algorithms for discovering OFDs, and a set of optimizations that efficiently prune the search space. Our experimental evaluation using real data show the scalability and accuracy of our algorithms.Comment: 12 page

Confessions of a Deluded Westerner

In this paper, I aim to make two general points. First, I claim that the discussions in Repetti (2017) assume different, sometimes conflicting, notions of free will, so the guiding question of the book is not as clear as it could be. Second, according to Buddhist tradition, the path to enlightenment requires rejecting the delusional belief in the existence of a persisting self. I claim that if there is no persisting self, there are no intentional actions; and, if there are no intentional actions, there is no hope for Buddhist enlightenment. Thus, rejecting the allegedly delusional belief in a persisting self has disastrous consequences, both for the existence of intentional action and for Buddhist soteriology

Integrative Humanism: Extensions and Clarifications

When we talk of African philosophy as a different philosophical tradition we do not wish to suggest that it studies different range of realities from those that concern the other philosophical traditions. What we demonstrate is the difference that arises in approach or method naturally informed by the resident logic. Thus in African philosophy we study ultimate reality of which being is at the center. What being and even nothingness mean for us is not the same with what they mean in other traditions. Unity: we sometimes say that being is one single whole without wishing to say that this view is monistic. In this light we hold that being is complete with both physical and spiritual aspects. Duality: we also share the view on the duality in nature without insisting that this is strict and permanent. Duality for Africans is essentially a point of inferential departure not a terminal point. The dual arrangement of things in nature is to necessarily lead to a tripartite conception. Triadic conception: this is the terminal point of all inferences in African thought. Yes, there is duality in nature but they exist as fragments and contraries i.e. incomplete in themselves but capable of coming together to form a whole. Obtaining this fusion of contrary fragments represents an inference from duality to triadic conception of reality. What this African conception is all about is not that being is tripartite or dual but that the coming together of two aspects of being is necessary for the formation of being

Ontology acquisition and exchange of evolutionary product-brokering agents

Agent-based electronic commerce (e-commerce) has been booming with the development of the Internet and agent technologies. However, little effort has been devoted to exploring the learning and evolving capabilities of software agents. This paper addresses issues of evolving software agents in e-commerce applications. An agent structure with evolution features is proposed with a focus on internal hierarchical knowledge. We argue that knowledge base of agents should be the cornerstone for their evolution capabilities, and agents can enhance their knowledge bases by exchanging knowledge with other agents. In this paper, product ontology is chosen as an instance of knowledge base. We propose a new approach to facilitate ontology exchange among e-commerce agents. The ontology exchange model and its formalities are elaborated. Product-brokering agents have been designed and implemented, which accomplish the ontology exchange process from request to integration

Materialism and the Resurrection: Are the Prospects Improving?

In 1999 Dean Zimmerman proposed a "falling elevator model" for a bodily resurrection consistent with materialism. Recently, he has defended the model against objections, and a slightly different version has been defended by Timothy O’Connor and Jonathan Jacobs. This article considers both sets of responses, and finds them at best partially successful; a new objection, not previously discussed, is also introduced. It is concluded that the prospects for the falling-elevator model, in either version, are not brigh

From fratricide to security community : re-theorising difference in the constitution of Nordic peace

This article utilises a revisionist account of the emergence of Nordic peace in the 19th century to open up space for rethinking and re-theorising the constitutive dynamics underlying security communities. While the Nordic case is often considered a prime example of a security community the article argues it did not emerge in the way usually claimed. First, security did not figure as a key constitutive argument as assumed by traditional security community theorising; second, togetherness did not emerge because of difference being traded for enhanced similarity. In fact, security was side-lined and difference re-interpreted rather than erased in forging ontologically safe identities

Narrative environments: how do they matter?

The significance and possible senses of the phrase 'narrative environment' are explored. It is argued that 'narrative environment' is not only polysemous but also paradoxical; not only representational but also performative; and not just performatively repetitive but also reflexive and constitutive. As such, it is useful for understanding the world of the early 21st century. Thus, while the phrase narrative environment can be used to denote highly capitalised, highly regulated corporate forms, i.e. "brandscapes", it can also be understood as a metaphor for the emerging reflexive knowledge-work-places in the ouroboric, paradoxical economies of the 21st century. Narrative environments are the media and the materialities through which we come to comprehend that world and to act in those economies. Narrative environments are therefore, sophistically, performative-representative both of the corporate dominance of life worlds and of the undoing of that dominance, through the iterative responses to the paradoxical injunction: "learn to live"
