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.

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.

Public space : its mythopoetic foundations and the limits of the law

Drawing on William Dawes' unpublished notebooks on the Indigenous languages spoken around Sydney Cove at the time of white settlement, this article hopes to provoke critical reflection on the limits of the law. Dawes' record of communication with Patyegarang documents a transaction that was both political and erotic, both about the law and in defiance of it. In performances that were gestural as well as verbal, they marked out a middle ground where the laws governing both of them were placed in parentheses and new, provisional, rules of exchange improvised. This article notices the existence of this middle ground, and marks its disappearance in subsequent legal discourse about the status of Indigenous people. Ultimately, it offers a reflection on the laws that govern the meeting place which the middle ground underwrites. That is, before public space became fixed for the legally binding discourse of politics, it was mobile and self-constituting. Is this simply a myth or is it a mythopoetic mechanism for rethinking the grounding of law in Australia? If it is the latter, then the next step will be to establish a middle ground of exchange with Indigenous law-giving systems.

Noncooperative foundations of the area monotonic solution

Given a finite set of alternatives, players alternate making offers. Player 1 offers some alternative that 2 can accept or veto. If 2 accepts, it is enforced, and the game ends. Otherwise, 2 makes a counteroffer among the remaining alternatives, and so on. If all alternatives are vetoed, a disagreement alternative is enforced. First, we characterize the unique outcome of any subgame perfect equilibrium of this game. Then, we show that this outcome converges to the Area Monotonic Solution if the alternatives are uniformly distributed over the bargaining set, and as the number of alternatives tends to infinity.

Noncooperative foundations for the Kalai-Smorodinsky and equal sacrifice solutions via prominence structures

In bargaining, players may adopt different prominence structures when making demands: (i) each player might use (1/N)th of his maximum monetary payoff as the prominence level or (ii) players might use a common prominence level. This paper considers a scheme in which players alternate making demands. It turns out that if the prominence levels described by (i) are used and if players have utilities linear in money, the outcome of this scheme converges to that of the Kalai-Smorodinsky solution as players' prominence levels get smaller. If the common prominence level of (ii) is used and if players have identical constant marginal utilities of money, the outcome of this scheme converges to that of the equal sacrifice solution as that prominence level gets smaller.
