Recourse against Judgments in the Netherlands
No full textIn the 1980s, the Netherlands witnessed the start of a comprehensive programme of reform in the fields of judicial organisation and procedure. The reform programme consists of three stages, of which the first has now been completed. This has, amongst other things, resulted in the consolidation of several administrative procedures which were formerly adjudicated by different judicial bodies, in the Arrondissementsrechtbank. Consequently, the Arrondissementsrechtbank has obtained extensive administrative jurisdiction together with its jurisdiction in civil and criminal cases. As part of the reforms in the second stage, a bill has been submitted to Parliament which contains changes in the court structure. It is proposed to abolish the Kantongerecht and to reallocate its jurisdiction to the Arrondissementsrechtbank, transforming the latter court into a general first-instance court. In addition, the bill contains changes in the Code of Civil Procedure. In the present report the author discusses the current situation January 1998
Bifurcation Routes in Financial Markets
No full textThe heterogeneity of expectations among traders introduces an important non-linearity into the financial markets. In a series of papers, Brock and Hommes, propose to model economic and financial markets as adaptive belief systems. Asset price fluctuations in adaptive belief systems are characterized by phases of close-to-the-fundamental-price fluctuations, phases of optimism where most agents follow an upward price trend, and phases of pessimism with small or large market crashes. In this paper will be discussed the EMH benchmark and forecasting rules of fundamentals and trend extrapolators. Some illustrative examples are supplied.heterogeneity of expectations, adaptive belief systems, forecasting rules, fundamentals, trend extrapolators equations, limit cycles, asymptotical stability
John Ploughman's Talk or Plain Advice for Plain People.
No full textI admit that I have read only two pages of this book (154-5). It seems a non-stop barrage of one-liners. The author does indeed, as the cover illustration suggests, take the bull by the horns! I picked the book up because its frontispiece of Aesop's fox and crow depicts the book's insight: The fox admires the cheese, not the raven (154). My two pages had lots of good zingers in them, like He who believes in promises made at elections has long ears, and may try to eat thistles. I suspect there are many more fable-related proverbs along the way in the book, but for now I will let someone else find them. This printing represents the 544th thousand.This is a hardbound book (hard cover)C.H. Spurgeo
Can the principle of maximum entropy production be used to predict the steady states of a Rayleigh-Bernard convective system?
No full textThe principle of Maximum Entropy Production (MEP) has been successfully used to reproduce the steady states of a range of non-equilibrium systems. Here we investigate MEP and maximum heat flux extremum principles directly via the simulation of a Rayleigh-Bernard convective system implemented as a lattice gas model. Heat flux and entropy production emerges in this system via the resolution of particle interactions. In the spirit of other related works, we use a reductionist approach, creating a lattice-Boltzmann model to produce steady-convective states between reservoirs of different temperatures. Convection cells emerge that show meta-stability where a given lattice size is able to support a range of convective states.Slow expansion and contraction of the model lattice, implemented by addition and subtraction of vertices, shows hysteresis loops where stable convection cells are expanded to regions wherein they become meta-stable, and eventually transition into more stable configurations. The maximally stable state is found to be that which maximises the rate of heat transfer, which is only equivalent to maximum internal entropy production in a strong forcing regime, while it is consistent with minimising entropy production in a weak forcing case. These results demonstrate the utility of lattice-Boltzmann models for future studies of non-equilibrium systems, and highlight the importance of dissipation and forcing rates in disambiguating proposed extremum principles
The equilibrium model for the effect of temperature on enzymes: Insights and implications
No full textA new, experimentally-validated “Equilibrium Model” describes the effect of temperature on enzymes, and provides a new mechanism for the reversible loss of enzyme activity with temperature. It incorporates two new, fundamental parameters that allow a complete description of the effect of temperature on enzyme activity: ΔHeq and Teq. ΔHeq emerges as an intrinsic and quantitative measure of enzyme eurythermal adaptation, while Teq, the equilibrium temperature, has fundamental and technological significance for our understanding of the effect of temperature on enzymatic reactions. For biotechnological purposes, these parameters need to be considered when enzymes are applied or engineered for activity at high temperatures
