The dynamic interaction between mountain pine beetles (MPB) and one of its hosts is reviewed briefly. The ‘local’ projection of a partial differential equation model describing this interaction is employed in model parameter estimation. Methods and assumptions for estimating non-fitted parameter values are given. Assigning values to non-fitted parameters, direct and indirect parametrization tec...

While there exist a number of papers describing the theory of signal detection, it appears that many psychologists are not aware of the ease with which signal detection theory can be applied, the range of applications possible, or the limitations of signal detection theory. This paper briefly summarizes the assumptions of signal detection theory and describes the procedures, the limitations, an...

The Cognitive Dimensions framework has inspired research both more and less varied than expected. In this paper we revisit the original aims and briefly describe some subsequent research, to consider whether the original aims were too austere in rejecting knowledge-based dimensions; whether the dimensions can be shown to have real-world relevance; and whether their definitions can be improved, ...

This talk begins with some history and basic facts about string theory and its connections with strong interactions. Comparisons of stacks of Dirichlet branes with curved backgrounds produced by them are used to motivate the AdS/CFT correspondence between superconformal gauge theory and string theory on a product of Anti-de Sitter space and a compact manifold. The ensuing duality between semi-c...

As might be predicted of any book by Dr. Hunter, this is readable, comprehensive, accurate and stimulating. The only pity is that although his chapters on history and legislation recognise the importance of neurosis and its preventability, there is hardly another reference to it in the bulk of the book describing occupational diseases.

Abstract Envisaging how secure systems might be attacked is difficult without adequate attacker models or relying on sterotypes. Defamiliarisation removes this need for a priori domain knowledge and encourages designers to think critically about system properties otherwise considere...

1. Here, I present a new,multifunctional phylogenetics package, phytools, for the R statistical computing environment. 2. The focus of the package is on methods for phylogenetic comparative biology; however, it also includes tools for tree inference, phylogeny input ⁄output, plotting, manipulation and several other tasks. 3. I describe and tabulate the major methods implemented in phytools, and...
