Orientational Ordering and Dynamics of Rodlike Polyelectrolytes

The interplay between electrostatic interactions and orientational correlations is studied for a model system of charged rods positioned on a chain, using Monte Carlo simulation techniques. It is shown that the coupling brings about the notion of {\em electrostatic frustration}, which in turn results in: (i) a rich variety of novel orientational orderings such as chiral phases, and (ii) an inherently slow dynamics characterized by stretched-exponential behavior in the relaxation functions of the system.Comment: 7 pages, 10 figure

Towards a North American Cabotage Regime: A Canadian Perspective

Throughout the 1970s and 1980s, Canada studied the impact of its cabotage legislation thoroughly and opted to provide protection of the domestic shipping market with new legislation in 1992. This paper traces the decision-making process through this period, and the concurrent discussions within NAFTA under negotiations for liberalization of trade in services. Now that Canada has 13 years experience with the existing cabotage legislation, and has adopted a policy to promote the development of short sea shipping, this paper evaluates Canada’s shipping policy options in order to identify if changes are required given the new policy environment

'The heart of what we do': policies on teaching, learning and assessment in the learning and skills sector

One of the stated aims of government policy in England is to put teaching, training,and learning at the heart of the learning and skills system. This paper provides a critical review of policies on teaching, learning and assessment in the learning and skills sector over the past five years. It draws upon data collected and analysed in the early stages of an ESRC-funded Teaching and Learning Research Programme project. Using evidence from policy sources, we argue that despite policy rhetoric about devolution of responsibility to the 'front line', the dominant 'images' that government has of putting teaching, learning and assessment at the heart of the Learning and Skills Sector involves a narrow concept of learning and skills; an idealisation of learner agency lacking an appreciation of the pivotal role of the learner/tutor relationship and a top-down view of change in which central government agencies are relied on to secure education standards

A century of Zoology and Entomology at Rhodes University, 1905 to 2005

The history of the Department of Zoology & Entomology at Rhodes University is traced from its origin with a single staff member, through the era of permanent heads of department to the present day staff. Significant achievements and developments in teaching and research are highlighted, and some anecdotal material is included
