A logical framework for knowledge sharing in multi-agent systems

The issue of knowledge sharing has been an important topic in multi-agent research. Knowledge sharing leads to that agents analyze, judge and synthesize the told information so as to make agents’ own knowledge. To match these applications, this paper builds a logical framework for knowledge sharing among agents. We develop a multimodal logic for reasoning about both agents’ knowledge and told information. For formalizing the relationship between knowledge and told information, we present a framework of semantics, with respect to which a sound and complete proof theory is given.

Global perspectives on the politics of multiculturalism in the 21st century: a case study analysis

Multiculturalism is now seen by many of its critics as the source of intercultural and social tensions, fostering communal segregation and social conflicts. While the cultural diversity of contemporary societies has to be acknowledged as an empirical and demographic fact, whether multiculturalism as a policy offers an optimal conduit for intercultural understanding and social harmony has become increasingly a matter of polarised public debate.
This book examines the contested philosophical foundations of multiculturalism and its, often controversial, applications in the context of migrant societies. It also explores the current theoretical debates about the extent to which multiculturalism, and related conceptual constructs, can account for the various ethical challenges and policy dilemmas surrounding the management of cultural diversity in our contemporary societies. The authors consider common conceptual and empirical features from a transnational perspective through analysis of the case studies of Australia, Canada, Columbia, Germany, New Zealand, the United Kingdom and Uruguay.

Exploring the foundations of practicing online collaboration

In collaborative learning, instruction is learner-centered rather than teacher-centered and knowledge is viewed as a social construct, facilitated by peer interaction, evaluation and mutual support [1]. Such computer supported collaborative learning (CSCL) enables and encourages learners to confer, reflect and help to develop meaningful learning in an environment where significant learning can be achieved through interactions supported by electronic communication and discourse [2]. This paper proposes a theory that supports educational collaboration in a peer-to-peer computing environment, thus blending the two disciplines.

Che Vuoi? Politico-philosophical remarks on Leo Strauss' Spinoza

Rumors surrounding the Hebraic-American classical philosopher Leo Strauss’ supposed influence on leading neoconservative politicians and commentators make reconsidering Leo Strauss’ thought and legacy a philosophical task of the first political importance today. A host of articles have appeared by students and (more recently) books by Stephen Smith (2006), Heinrich Meier (2006) and Catherine and Michael Zuckert (2006). This essay is proffered as a critical contribution, by a non-Straussian student, to this literature. Its methodology and justification is to return to and reconsider Strauss’ earliest works, on the ‘political theology’ of Benedict de Spinoza. The paper argues two theses. The first is that the popular depiction of Strauss as an esoteric Nietzschean hiding behind a ‘noble’ classical or theological veneer importantly misses the mark. The second is that Strauss’ early work shows his proximity, via Jacobi, to the Heideggerian disclosure of the groundless grounds of philosophical reason, given which one must extra-rationally choose reason over faith. One striking implication of this argument, in the contemporary political climate, is to underscore the unlikely convergence between the philosophical sources of neoconservative and the ‘post-structuralist’ thought associated with much of the intellectual left in France and the Anglophone world. Yet in contrast to the widespread image of Strauss, I argue that the mature Strauss’ continuing commitment to this decisionistic framework is in fact most clear is his ‘exoteric,’ public statements on religion – i.e. it is not the ‘esoteric’ purloined letter Strauss’ critics seek out. The reason for Strauss’ continuing public advocacy of the impossibility of reason’s disproving faith, I propose, highlights the primarily political (versus philosophical) nature of this turn: in Strauss’ conservative acceptance of the political necessity of religion for social order, framed in terms of a revised commitment to the ‘medieval’ (versus modern) enlightenment of Maimonides and Farabi.

Grounded theory as foundations for methods in applied ontology

Research into domain specific ontologies is difficult to treat empirically. This is because it is difficult to ground domain ontology while simultaneously being true to its guiding philosophy or theory. Further, ontology generation is often introspective and reflective or relies on experts for ontology generation. Even those relying on expert generation lack rigour and tend to be more ad-hoc. We ask how Grounded Theory can be used to generate domain specific ontologies where appropriate high level theory and suitable textual data sources are available. We are undertaking generation of a domain ontology for the discipline of information systems by applying the Grounded Theory method. Specifically we are using Roman Ingarden’s theory of scientific works to seed a coding family and adapting the method to ask relevant questions when analysing rich textual data. We have found that a guiding ontological theory, such as Ingarden’s, can be used to seed a coding family giving rise to a viable method for generating ontologies for research. This is significant because Grounded Theory may be one of the key methods for generating ontologies where substantial uniform quality text is available to the ontologist. We also present our partial analysis of information systems research.

Cadaveric vs. live-donor kidney transplants : theoretical foundations of interaction between institutions and inequality

In 1991, the World Health Assembly approved a set of Guiding Principles which emphasize voluntary donation, non-commercialization and a preference for cadavers over living donors” (World Health Organization). The objective of this paper is to identify the factors that affect the ratio of cadaveric transplants to all transplants. This paper first provides informational background on problems surrounding kidney transplants and then uses a theoretical framework which employs standard economic assumptions but incorporates a setup where the persons needing kidneys can obtain it from their compatible relatives or purchase it from individuals who are willing to sell one of their kidneys. The methods of economic theoretical analyses are used where following definitions and assumptions some conclusions are drawn. This paper finds that factors such as inequality, rule of law and religion have significant effect on the ratio of cadaveric transplants to all transplants. The paper concludes that improvement in equality and in rule of law will increase the use of cadaveric kidney transplants. In addition, fighting religious beliefs against cadaveric kidney transplants too will lead to a higher ratio of cadaveric transplants to all transplants.
