Evaluation of GHA’s youth diversionary programme

To assist with funding decisions in this area and to build an evidence base, GHA commissioned an evaluation of a selection of its youth diversionary programmes in 2007

Mixed tenure orthodoxy: practitioner reflections on policy effects

This article examines mixed tenure as a policy orthodoxy. It first sets out how mixed tenure may be considered to constitute an orthodoxy within planning, being generally accepted as a theory and practice even in the absence of supporting evidence. Five elements of this orthodoxy are identified, relating to (1) housing and the environment, (2) social change, (3) economic impacts, (4) sustainable communities, (5) and sociospatial integration. Interviews with practitioners involved with three social housing estates that have experienced mixed-tenure policy interventions are reported to consider why the implementation and effects of mixed tenure might not correspond with the orthodox understanding. It is argued that policy ambiguity and weaknesses in policy theory and specification, alongside practical constraints, lie behind incomplete and counterproductive policy implementation, but a belief in pursuing the policy orthodoxy persists nevertheless

Materiality & the audit report: It\u27s time for disclosure

The concept of materiality has received a lot of attention in recent years as high profile accounting scandals have plagued financial reporting. Auditing Standards from the PCAOB and the AICPA require that early in an audit engagement the auditor establish a preliminary level of materiality. This preliminary level of materiality, a dollar value, is used to determine the extent of audit testing that is performed. It can be changed as the audit progresses and key financial statement numbers change. Under current standards neither the preliminary nor final materiality number is disclosed. They are known only to the auditor. This paper examines the reasons why the materiality level is so carefully concealed. It is also suggests the benefits that would accrue to users of the financial statements if the auditor\u27s materiality level were disclosed in the auditor\u27s report

Weighing Neutrinos with Galaxy Cluster Surveys

Large future galaxy cluster surveys, combined with cosmic microwave background observations, can achieve a high sensitivity to the masses of cosmologically important neutrinos. We show that a weak lensing selected sample of ~100,000 clusters could tighten the current upper bound on the sum of masses of neutrino species by an order of magnitude, to a level of 0.03 eV. Since this statistical sensitivity is below the best existing lower limit on the mass of at least one neutrino species, a future detection is likely, provided that systematic errors can be controlled to a similar level.Comment: 4 pages, 1 figure, version accepted for publication in PR
