Role of Secondary Motifs in Fast Folding Polymers: A Dynamical Variational Principle
A fascinating and open question challenging biochemistry, physics and even
geometry is the presence of highly regular motifs such as alpha-helices in the
folded state of biopolymers and proteins. Stimulating explanations ranging from
chemical propensity to simple geometrical reasoning have been invoked to
rationalize the existence of such secondary structures. We formulate a
dynamical variational principle for selection in conformation space based on
the requirement that the backbone of the native state of biologically viable
polymers be rapidly accessible from the denatured state. The variational
principle is shown to result in the emergence of helical order in compact
structures.Comment: 4 pages, RevTex, 4 eps figure
Continuity and change - The planning and management of long distance walking routes in Scotland
In recent years a number of changes have taken place in Scotland in respect of issues of land management, access and the natural environment. These include the creation of Scotland’s first National Parks in 2002 and the introduction of the Land Reform (Scotland) Act 2003, which has enshrined in legislation the principle of responsible access in the countryside. The aim of this study was to consider the implications of these changes for a specific type of recreational land use in Scotland, Long Distance (Walking) Routes (LDRs). Using semi-structured interviews with representatives of a number of agencies and with other individuals closely involved with LDRs, the research considered the extent to which these changes have or may alter the rationale for the provision of LDRs, their funding and their management. The research indicates a need and a willingness to build on existing stakeholder approaches to management with a view to engaging a broader range of communities of interest. The main challenge for those involved with LDRs is how to fund future development of these routes. One aim of a more participatory stakeholder management approach is to help route managers to use public funds to lever funds from other source
Protein structures and optimal folding emerging from a geometrical variational principle
Novel numerical techniques, validated by an analysis of barnase and
chymotrypsin inhibitor, are used to elucidate the paramount role played by the
geometry of the protein backbone in steering the folding to the correct native
state. It is found that, irrespective of the sequence, the native state of a
protein has exceedingly large number of conformations with a given amount of
structural overlap compared to other compact artificial backbones; moreover the
conformational entropies of unrelated proteins of the same length are nearly
equal at any given stage of folding. These results are suggestive of an
extremality principle underlying protein evolution, which, in turn, is shown to
be associated with the emergence of secondary structures.Comment: Revtex, 5 pages, 5 postscript figure

Accuracy of responses from postal surveys about continuing medical education and information behavior: experiences from a survey among German diabetologists
BACKGROUND: Postal surveys are a popular instrument for studies about continuing medical education habits. But little is known about the accuracy of responses in such surveys. The objective of this study was to quantify the magnitude of inaccurate responses in a postal survey among physicians. METHODS: A sub-analysis of a questionnaire about continuing medical education habits and information management was performed. The five variables used for the quantitative analysis are based on a question about the knowledge of a fictitious technical term and on inconsistencies in contingency tables of answers to logically connected questions. RESULTS: Response rate was 52%. Non-response bias is possible but seems not very likely since an association between demographic variables and inconsistent responses could not be found. About 10% of responses were inaccurate according to the definition. CONCLUSION: It was shown that a sub-analysis of a questionnaire makes a quantification of inaccurate responses in postal surveys possible. This sub-analysis revealed that a notable portion of responses in a postal survey about continuing medical education habits and information management was inaccurate
