2.1 Introduction

In this section we are going to review the different needs that drive the creation of corporate governance frameworks. The contingent model of regulation applies to financial reporting: the idea that equilibrium in regulation exists, but is broken by some intrusive event, often a financial scandal. This leads to a search for a revision of the rules, and a new equilibrium is worked out. This is very much a pattern that drives change in corporate governance.

9. The Marxian Challenge
Moral Foundations of Politics (PLSC 118) Marxism is the second Enlightenment tradition upon which the course will focus. Contrary to popular belief, Marx did not hate capitalism but derived from economic analysis that it would self-destruct and lead to socialism. It is also a myth that Marx did not care about freedom; he was only egalitarian in the sense that he wanted everyone to have freedom. Ergo, Professor Shapiro asserts that Marx's dialectical materialism is as committed to the two princi

Cell Signalling
A chapter which describes the mechanisms of signal transduction in a eukaryotic cell, including the activation of G-proteins and kinase cascades (49 figures). The unit is intended as ~10hrs study at level 2/3. It also provides background reading for the experimental investigation 'Investigating intracellular signalling pathways' (http://open.jorum.ac.uk/xmlui/handle/123456789/1581).

Virtual laboratories in Molecular and Cell Biology - Immuno-electron-microscopy
A virtual laboratory that includes immuno-gold labelling and transmission electron micrography (immuno-EM). It allows the student to study intracellular-traffic pathways of two cell-surface receptor molecules, following stimulation of the cells with their specific ligand, for different time periods. The programme first introduces the theory underlying the techniques and includes a video of EM work in a real laboratory. The student is then taken through a series of questions which requires them t

Virtual laboratories in Molecular and Cell Biology - Intracellular signalling
A virtual laboratory which allows users to analyse intracellular signalling pathways. The programme allows the student to stimulate cells for different periods of time and analyse phosphorylation/activation of kinases in the signalling pathways, using SDS-PAGE and immunoblotting. Use of different cell types (dominant-negative mutants) and pull-down assays allows them to derive the hierarchy in the signalling pathways. The programme first introduces the theory behind the techniques. It then takes

Virtual laboratories in Molecular and Cell Biology - SDS-PAGE
A protein analysis laboratory using SDS-PAGE, western-blotting and endoprotease digestion. The programme includes a section on the theory of the techniques, a video demonstration in a real laboratory, and a series of questions which guide the students through the structural analysis of model proteins (3 are included). Students go to the virtual laboratory and devise their own experiments in order to determine the molecular weight, subunit composition etc of the proteins. Results (gels and blots)

Back to basics: Scientists discover a fundamental mechanism for cell organization (w/Video)
This article outlines the discovery of a mechanism of assembing and localizing subcellular structures in the development of the embryo. According to the researchers, cells use a very simple phase transition similar to water vapor condensation to assemble subcellular structures during development. This article includes a short video portraying the researchers findings. This is a useful site for developmental biology and embryology.

FOAMCARP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. Calcium carbonate is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a fine and relatively uniform cell structure.

Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.
