Why is the Greek economy collapsing? A simple tale of high multipliers and low exports. CEPS Commentary, 21 December 2012

In an attempt to understand why the Greek economy is collapsing, this Commentary points out two key aspects that are often overlooked – the country’s large multiplier and a bad export performance. When combined with the need for a large fiscal adjustment, these factors help explain how fiscal consolidation in Greece has been associated with such a large drop in GDP.

21-Deoxycortisone (17 alpha-hydroxy4-pregnene-3,11,20-trione)

The title compound, C21H28O4, a synthetic glucocorticoid, crystallizes with a single molecule in the asymmetric unit. Ring A is almost in a half-chair conformation, rings B and C are almost in chair conformations, and ring D is between a twist and a 13 beta-envelope conformation. The A/B ring junction is quasi-trans, whereas the B/C and C/D ring junctions both approach trans characteristics. The molecule as a whole is slightly convex towards the beta side, with an angle of 9.60 (2)degrees between the C10-C19 and C13-C18 vectors. Molecular-packing and hydrogen-bonding (both intra- and inter-molecular) interactions play a major role in the structural association of the compound.

High-performance infrared filters for the HIRDLS 21-channel focal plane detector array

The High Resolution Dynamics Limb Sounder is described, with particular reference to the atmospheric measurements to be made and the rationale behind the measurement strategy. The demands this strategy places on the filters to be used in the instrument and the designs to which this leads to are described. A second set of filters at an intermediate image plane to reduce "Ghost Imaging" is discussed together with their required spectral properties. A method of combining the spectral characteristics of the primary and secondary filters in each channel are combined together with the spectral response of the detectors and other optical elements to obtain the system spectral response weighted appropriately for the Planck function and atmospheric limb absorption. This method is used to demonstrate whether the out-of-band spectral blocking requirement for a channel is being met and an example calculation is demonstrated showing how the blocking is built up for a representative channel. Finally, the techniques used to produce filters of the necessary sub-millimetre sizes together with the testing methods and procedures used to assess the environmental durability and establish space flight quality are discussed.

Local agenda 21 and planning practice: structural transformation or window dressing?

Local Agenda 21 seeks the meaningful involvement of a wide range of local groups and stakeholders in the formulation and implementation of public policy and a free flow of communication and discussion between them and their respective local authorities (and other areas and levels of decision-making). This paper explores the reality of this process using case study evidence from local planning practice in Liverpool (in the north of England) and Reading (in the south of the country). It concentrates on the interaction between LA21 groups and local planning authorities around the preparation of local land use plans and other policy initiatives and the day-to-day regulation of development permits. The paper builds on ‘New Institutionalist’ theory to explore the constraints and opportunities for significant transformations in social, political and economic ‘structures’ or ‘ways of doing things’ through the LA21 process. It concludes that the two cases provide evidence of mixed success in achieving such changes in established planning practices.
