Streamlining or watering down? Assessing the 'smartness' of policy and standards for the promotion of low and zero carbon homes in England 2010-15

The knowledge and enforcement problems faced by governments in defining traditional ‘command and control’ regulation are well known. Significant legal scholarship offers alternative models of ‘smart,’ ‘responsive’ environmental regulation, emphasising the need for policy instrument mixes, including the vital role of voluntary, industry-led sustainability standards. Yet, as is being increasingly recognised, these contributions leave open the need for detailed, qualitative evaluation of instrument mixes as a complement to primarily quantitative cost-benefit analyses that predominate in regulatory impact assessments by governments. Addressing this need, this paper evaluates policy and standards for low and zero carbon homes in England during the Coalition government (2010-2015) when the ecological modernisation discourse of the previous New Labour government became subsumed by a deregulation agenda. Our study, incorporating 70 stakeholder interviews, suggests that, in supplier-driven markets such as housing in England, a ‘smart’ mix of mandatory and voluntary standards requires a strong, central role for government in setting national, mandatory standards and supporting their delivery. There is an important potential supplementary role for voluntary tools and local authority discretion, though our study highlights problems that can arise when such different instruments promote diverging roadmaps towards a policy goal

IT in construction: aligning IT and business strategies

The extent to which information technology (IT) infrastructures and strategies are aligned with business processes and strategies varies widely along firms. The objective of this paper is to explain the success or failure of IT in construction firms by focusing on the alignment (or lack of it) between business strategy, IT strategy, organizational infrastructure, and IT infrastructure. It is hypothesized that the ‘fit’ among these elements, the domains of the Strategic Alignment Model, is positively related to the Business Value of IT in Construction. The IT Business Value is evaluated in terms of efficiency, effectiveness and business performance. By applying the Strategic Alignment Model to the Dutch construction industry, it is shown that the inadequate alignment between these domains is a major reason for the modest added business value from IT investments in this industry. The first lack of alignment is the technology shortfall: hence IT contributes in an inadequate way to strategic processes of construction firms. The second lack of alignment is the strategy-shortfall: hence the firm strategy impedes the implementation of IT that could generate a high business value

Synthesis of aromatic secondary diamines

A series of N-methyl substituted aromatic polyamides derived from the secondary aromatic diamines, 4,4'-bis(methylamino)diphenylmethane, 3,3'-bis(methylamino) diphenylmethane, 4,4'-bis(methylamino)benzophenone or 3,3'-bis(methylamino)benzophenone and isophthaloyl dichloride, terphthaloyl dichloride or 3,3'diphenylmethane dicarboxylic acid dichloride was prepared by high temperature solution polymerization in s-tetrachloroethane. Compared to analogous unsubstituted and partially N-methylated aromatic polyamides, the full N-methylated polyamides exhibited significantly lower glass transition temperatures, reduced crystallinity, improved thermal stability and good solubility in chlorinated solvents

Oxygen Isotopic Constraints on the Number and Origin of Basaltic Achondrite Parent Bodies

Our data show that HED meteorites have a homogeneous oxygen isotopic composition consistent with a magma ocean on Vesta. Ibitira, Asuka 881394, Pasamonte, and NWA 1240 probably come from separate parent asteroids

Optical and dc transport properties of a strongly correlated charge density wave system: exact solution in the ordered phase of the spinless Falicov-Kimball model with dynamical mean-field theory

We derive the dynamical mean-field theory equations for transport in an ordered charge-density-wave phase on a bipartite lattice. The formalism is applied to the spinless Falicov-Kimball model on a hypercubic lattice at half filling. We determine the many-body density of states, the dc charge and heat conductivities, and the optical conductivity. Vertex corrections continue to vanish within the ordered phase, but the density of states and the transport coefficients show anomalous behavior due to the rapid development of thermally activated subgap states. We also examine the optical sum rule and sum rules for the first three moments of the Green's functions within the ordered phase and see that the total optical spectral weight in the ordered phase either decreases or increases depending on the strength of the interactions.Comment: 14 pages, 14 figures, submitted to Phys.

Oxygen isotopic and petrological constraints on the origin and relationship of IIE iron meteorites and H chondrites

New oxygen isotopic measurements of IIEs and H chondrites are indistinguishable — strengthening a possible common origin for these groups. Combining oxygen results with mineralogy, the nature of their parent body or bodies can be explored

Tafassasset: The Saga Continues

In this study, we compare data for two separate Tafassasset stones and supply new oxygen isotope data for our sample. We include a discussion of the debate surrounding the classification of Tafassasset and offer a hypothesis for its origin based upon new information
