Innovation and failure in mechatronics design education
Innovative engineering design always has associated with it the risk of failure, and it is the role of the design engineer to mitigate the possibilities of failure in the final system. Education should however provide a safe space for students to both innovate and to learn about and from failures. However, pressures on course designers and students can result in their adopting a conservative, and risk averse, approach to problem solving. The paper therefore considers the nature of both innovation and failure, and looks at how these might be effectively combined within mechatronics design education
Travelling wave solutions in a negative nonlinear diffusion-reaction model
We use a geometric approach to prove the existence of smooth travelling wave
solutions of a nonlinear diffusion-reaction equation with logistic kinetics and
a convex nonlinear diffusivity function which changes sign twice in our domain
of interest. We determine the minimum wave speed, c*, and investigate its
relation to the spectral stability of the travelling wave solutions.Comment: 23 pages, 10 figure
Relative Wage Variation and Industry Location
Relative wages vary considerably across regions of the United Kingdom, with skill-abundant regions exhibiting lower skill premia than skill-scarce regions. This paper shows that the location of economic activity is correlated with the variation in relative wages. U.K. regions with low skill premia produce different sets of manufacturing industries than regions with high skill premia. Relative wages are also linked to subsequent economic development: over time, increases in the employment share of skill-intensive industries are greater in regions with lower initial skill premia. Both results suggest firms adjust production across and within regions in response to relative wage differences.
All is not equal.
Theory suggests that market forces should bring the relative pay of skilled workers into line in different regions within a country. Andrew Bernard, Stephen Redding, Peter Schott and Helen Simpson show that this is not the case for the UK and argue that regional industrial policy needs to take this into account.

Representations of the fundamental group of a surface in PU(p,q) and holomorphic triples
We count the connected components in the moduli space of
PU(p,q)-representations of the fundamental group for a closed oriented surface.
The components are labelled by pairs of integers which arise as topological
invariants of the flat bundles associated to the representations. Our results
show that for each allowed value of these invariants, which are bounded by a
Milnor-Wood type inequality, there is a unique non-empty connected component.
Interpreting the moduli space of representations as a moduli space of Higgs
bundles, we take a Morse theoretic approach using a certain smooth proper
function on the Higgs moduli space. A key step is the identification of the
function's local minima as moduli spaces of holomorphic triples. We prove that
these moduli spaces of triples are non-empty and irreducible.Comment: 6 pages, to appear in C. R. Acad. Sci. Paris Ser. I Mat
Governing the regulators – applying experience
Emphsizing more effective law rather than more law, this paper provides a perpective from within government that argues for a better appreciation of what is required to ensure that regulation is effective in a New Zealand context.
Using building controls, financial markets regulation and occupational health and safety as examples, this paper presents an analysis of the changes to the regulatory landscape, and in particular the role of regulators as a particular facet of regulatory design.
