On behavior of the fifth algebraic transfer

In this paper, we show that Singer's fifth transfer is not an epimorphism in degree 11. More precisely, it does not detect the element P(h_2) in Ext_A^{5,16}(F_2,F_2).Comment: This is the version published by Geometry & Topology Monographs on 14 November 200

Reasoning about Action: An Argumentation - Theoretic Approach

We present a uniform non-monotonic solution to the problems of reasoning about action on the basis of an argumentation-theoretic approach. Our theory is provably correct relative to a sensible minimisation policy introduced on top of a temporal propositional logic. Sophisticated problem domains can be formalised in our framework. As much attention of researchers in the field has been paid to the traditional and basic problems in reasoning about actions such as the frame, the qualification and the ramification problems, approaches to these problems within our formalisation lie at heart of the expositions presented in this paper

Towards Building Curricula for Fostering Autonomous Vocabulary Learning: a Case of Vietnamese EFL Context

Adopting a problem-solving approach to curriculum design, this paper is an attempt to illustrate a case of a Vietnamese university where the vocabulary learning and teaching practices are not satisfactory. Drawing on relevant research literature in the field, it first identified the problems associated with the underachievement of learners in terms of vocabulary learning. Several suggestions would then be made towards integrating into the existing curricula elements of a learner autonomy strand where learners find ways to relate the public and private learning domains
