Towards Charity Accountability: Narrowing the gap between provision and needs?

Although charities currently play a rich and varied role in modern society, their continued success is dependent upon the public's trust. With respect to charity accountability, two key questions emerge: to whom is a charity accountable; and what form should that account take? Despite the widespread acceptance that charities should discharge accountability, there is limited knowledge of the relative importance of different stakeholder groups and whether the information currently being disclosed meets their needs. Using extensive document analysis and a survey of stakeholders, this research explores these issues in the context of the top 100 UK fundraising charities. Furthermore, it compares the results with much earlier research to identify changes over time.

Parent Issues: How Life on Mars Negotiates a Television Generation Gap

In defining what he termed 'Television's Second Golden Age', Robert J.Thompson refers to characteristics such as being 'not regular TV', internal continuity, mixed genres but an aspiration towards 'realism', complex writing, self-consciousness and intertextuality. Such characteristics are displayed by the BBC series Life on Mars (2006-2007) which intermingles the Seventies tough cop show with psychological fantasy. This chapter examines the way that the series can be understood as a dramatisation of the negotiation that the creators undertook with their Seventies source material to update it for the values and qualities of contemporary television drama. It will emphasise the importance of television in the generation of the imagined 1973 and its characters, but also as an ongoing connection between the real and the imagined within the programme, including forming a breach of the boundaries between the two. Sam's actions within his Seventies world to remake it to include his own ideas of justice and due process while retaining the passion and freedom of action that the milieu provides will also be be examined in relation to the series' creators' needs to remake the Seventies tough-cop show in the light of modern social and media mores. The paper will also consider how Sam has to come to terms with his father's crimes, as the series' creators had to come to terms with the 'crimes' of taste, morality and approach of their 'parent' programmes from the Seventies' Golden Age.

An updated moraine map of Far NE Russia

Barr and Clark published a series of maps depicting the distribution of end moraines across Far NE Russia. These
moraines outlined the former distribution and dimensions of glaciers, and were identified through the analysis of
Landsat ETM+ satellite images (15- and 30-m resolution). Now, a number of freely available digital elevation
model (DEM) datasets are available, which cover the entire 4 million km2 of Far NE Russia. These include
the 30-m resolution ASTER GDEM and the 90-m resolution Viewfinder Panorama DEM. Here we use these
datasets, in conjunction with Landsat ETM+ images, to complete the process of systematically and
comprehensively mapping end moraines. With the aid of the DEMs described above, here we present a total
dataset of 8414 moraines, which almost quadruples the inventory of Barr and Clark. This increase in the
number of moraines is considered to reflect the utility of the DEMs for mapping glacial landforms. In terms of
moraine distribution, the Barr and Clark map and the one presented here are comparable, with moraines found
to cluster in highland regions and upon adjacent lowlands, attesting to the former occupation of the region by
mountain-centred ice masses. This record is considered to reflect palaeoclimatic and topographic controls upon
the extent and dynamics of palaeoglaciers, as well as spatial variability in moraine preservation.

An Impact Of Various Shroud Bleed Slot Configurations And Cavity Vanes On Compressor Map Width And The Inducer Flow Field

This paper describes an investigation of map width enhancement and a detailed analysis of the inducer flow field due to various bleed slot configurations and vanes in the annular cavity of a turbocharger centrifugal compressor. The compressor under investigation is used in a turbocharger application for a heavy duty diesel engine of approximately 400 hp. This investigation has been undertaken using a computational fluid dynamics (CFD) model of the full compressor stage, which includes a manual multiblock-structured grid generation method. The influence of the bleed slot flow on the inducer flow field at a range of operating conditions has been analyzed, highlighting the improvement in surge and choked flow capability. The impact of the bleed slot geometry variations and the inclusion of cavity vanes on the inlet incidence angle have been studied in detail by considering the swirl component introduced at the leading edge by the recirculating flow through the slot. Further, the overall stage efficiency and the nonuniform flow field at the inducer inlet have been also analyzed. The analysis revealed that increasing the slot width has increased the map width by about 17%. However, it has a small impact on the efficiency, due to the frictional and mixing losses. Moreover, adding vanes in the cavity improved the pressure ratio and compressor performance noticeably. A detail analysis of the compressor with cavity vanes has also been presented.

Map Width Enhancement Technique for a Turbocharger Compressor

This paper presents an investigation of map width enhancement and the performance improvement of a turbocharger compressor using a series of static vanes in the annular cavity of a classical bleed slot system. The investigation has been carried out using both experimental and numerical analysis. The compressor stage used for this study is from a turbocharger unit used in heavy duty diesel engines of approximately 300 kW. Two types of vanes were designed and added to the annular cavity of the baseline classical bleed slot system. The purpose of the annular cavity vane technique is to remove some of the swirl that can be carried through the bleed slot system, which would influence the pressure
ratio. In addition to this, the series of cavity vanes provides a better guidance to the slot recirculating flow before it mixes with the impeller main inlet flow. Better guidance of the flow improves the mixing at the inducer inlet in the circumferential direction. As a consequence, the stability of the compressor is improved at lower flow rates and a wider map can be achieved. The impact of two cavity vane designs on the map width and performance of the compressor was highlighted through a detailed analysis of the impeller flow field. The numerical and experimental study revealed that an effective vane design can improve the map width and pressure ratio characteristic without an efficiency penalty compared to the classical bleed slot system without vanes. The comparison study between the cavity vane and noncavity vane configurations presented in this paper showed that the map width was improved by 14.3% due to a significant reduction in surge flow and the peak pressure ratio was improved by 2.25% with the addition of a series of cavity vanes in the annular cavity of the bleed slot system.

Minding the Gap: Children with Disabilities and the United Nations Convention on the Rights of Persons with Disabilities

This chapter provides a critical assessment of the approach adopted by the United Nations Convention on the Rights of Persons with Disabilities (CRPD) towards children with disabilities and its implications for socializing States Parties to both ‘right’ and ‘rights’ behaviour. It discusses the ways in which ‘rights talk’ for children with disabilities, itself a relatively recent development in this context, has been predominantly needs based in its substantive content, and explores whether the exacerbated disadvantage experienced by children with disabilities as a result of the particular interaction between disability and childhood is effectively addressed and given due weight by the new Convention. The CRPD's provisions are discussed in the context of children with disabilities and their potential to provide effective redress assessed. The chapter concludes with some critical reflections on the extent to which the CRPD can really be understood as minding the gap for children with disabilities.

MAP kinase pathway signalling is essential for extracellular matrix determined mammary epithelial cell survival

Mammary epithelial cells in primary cell culture require both growth factors and specific extracellular matrix (ECM)-attachment for survival. Here we demonstrate for the first time that inhibition of the ECM-induced Erk 1/Erk 2 (p42/44 MAPK) pathway, by PD 98059, leads to apoptosis in these cells. Associated with this cell death is a possible compensatory signalling through the p38 MAP kinase pathway the inhibition of which, by SB 203580, leads to a more rapid onset of apoptosis. This provides evidence for a hitherto undescribed Erk 1/Erk 2 to p38 MAP kinase pathway 'cross-talk' that is essential for the survival of these cells. The cell death associated with inhibition of these two MAP kinase pathways however, occurred in the presence of insulin that activates the classical PI-3 kinase-dependent Akt/PKB survival signals and Akt phosphorylation. Cell death induced by inhibition of the MAP kinase pathways did not affect Akt phosphorylation and may, thus, be independent of PI-3 kinase signalling.

Effect of spatial nonlocality on the density functional band gap

We show that for a large class of exchange-correlation functionals the local exchange-correlation potential obtained within an optimized effective potential severely underestimates the band gap. On the other hand, the corresponding nonlocal potential obtained from a generalized Kohn-Sham scheme provides a much better description of the band gap, in good agreement with experiments. These results strongly indicate that a local exchange-correlation potential, however good the exchange-correlation approximation, cannot capture the delicate interplay between correlation effects and spatial localization in the KS band structure, unless the (cumbersome) contribution from the derivative discontinuity of the exchange-correlation energy functional is considered.
