A proposal of categorisation for analysing inductive reasoning

We present an analysis of the inductive reasoning of twelve Spanish secondary students in a mathematical problem-solving context. Students were interviewed while they worked on two different problems. Based on Polya´s steps and Reid’s stages for a process of inductive reasoning, we propose a more precise categorization for analyzing this kind of reasoning in our particular context. In this paper we present some results of a wider investigation (Cañadas, 2002).

Private purpose trusts: a reform proposal

Argues for the introduction of statutory reform to enable valid private purpose trusts to be created by those wishing to make testamentary gifts for non-charitable purposes, with no human beneficiary. Examines the rationale employed in cases where the validity of a private purpose trust has been upheld despite the absence of a human beneficiary. Considers the approaches adopted by five offshore jurisdictions when introducing purpose trust legislation. Identifies key features to be included in any new purpose trust legislation introduced in the UK.

Hybrid cluster state proposal for a quantum game

We propose an experimental implementation of a quantum game algorithm in a hybrid scheme combining the quantum circuit approach and the cluster state model. An economical cluster configuration is suggested to embody a quantum version of the Prisoners' Dilemma. Our proposal is shown to be within the experimental state of the art and can be realized with existing technology. The effects of relevant experimental imperfections are also carefully examined.

The proposal of democratic citizenship in Hannah Arendt

The main purpose of this paper is to analyze Hannah Arendt’s citizenship proposal. The central thesis is that this proposal is possible in contemporary democracies, and it is adequate for developing and strengthening of political action. The work is divided in five sections. In the first, we develop a brief introduction on the studied issue. In the second and third section, we analyze, respec-tively, political and moral conditions that enable democratic citizenship, and the conditions that hinder the exercise of the same, according to Arendt. Then, we reflect critically on Arendt’s citizenship proposal. Finally, we conclude and we propose a set of civic challenges relate to current democracies in light of the above proposal.
