Community involvement in urban nature conservation : case studies of the Urban Wildlife Group 1980-85

The effectiveness of the strategies employed by the Urban Wildlife Group (a voluntary conservation organisation) to provide and manage three urban nature parks has been evaluated, using a multiple methods methodology. Where the level of community interest and commitment to a project is high, the utilisation of the community nature park strategy (to maximise benefits to UWG and the community) is warranted. Where the level of interest and commitment of the local community is low, a strategy designed to encourage limited involvement of the community is most effective and efficient. The campaign strategy, whereby the community and UWG take direct action to oppose a threat of undesirable development on a nature park, is assessed to be a sub-strategy, rather than a strategy in its own right. Questionnaire surveys and observations studies have revealed that urban people appreciate and indeed demand access to nature parks in urban areas, which have similar amenity value to that provided by countryside recreation sites. Urban nature parks are valued for their natural character, natural features (trees, wild flowers) peace and quiet, wildlife and openness. People use these sites for a mixture of informal and mainly passive activities, such as walking and dog walking. They appear to be of particular value to children for physical and imaginative play. The exact input of time and resources that UWG has committed to the projects has depended on the level of input of the local authority. The evidence indicates that the necessary technical expertise needed to produce and manage urban nature parks, using a user-oriented approach is not adequately provided by local authorities. The methods used in this research are presented as an `evaluation kit' that may be used by practitioners and researchers to evaluate the effectiveness of a wide range of different open spaces and the strategies employed to provide and manage them.

Political leadership:character and performance. A comparative analysis of British political leadership, 1997-2010.

Classical and contemporary scholarship on leadership has referred to political performance and the ability of political actors to deploy the self to political purpose. Literature on contemporary British politics (Hennessy, 2001; Marquand, 2008, King, 2009) has highlighted the qualitative shift in political leadership from the mid-1990s towards a focus upon the image, style, celebrity and performance of political leaders, and the shift towards the presidentialisation or semi-presidentialisation of the prime minister (Foley, 2001). However, the literature has lacked a focus upon political performance and a methodology for assessing leadership performance within cultural and institutional contexts. This thesis assesses British political leadership performance from 1997-2010 through the proposal of a framework of political performance to suit comparative purpose. The framework consisting of culture, institutions and performance is used to assess the performance of the case studies (Tony Blair, Gordon Brown and David Cameron, and Gordon Brown, David Cameron and Nick Clegg in the televised Leaders’ Debates of 2010). The application of the framework to the case studies will allow us to a) analyse political performance within given cultural and institutional contexts; b) establish the character traits and other aspects of a politician’s political persona; and c) appraise the role and effects of performance and persona upon the political process.

In situ studies of structure-reactivity relations in biodiesel synthesis over nanocrystalline MgO

High temperature processing of solvothermally synthesised MgO nanoparticles promotes striking changes in their morphology, and surface chemical and electronic structure. As-prepared NanoMgO comprised ∼4 nm cubic periclase nanocrystals, interspersed within an amorphous Mg(OH)(OCH3) matrix. These crystallites appear predominantly (1 0 0) terminated, and the overall material exhibits carbonate and hydroxyl surface functionalities of predominantly weak/moderate base character. Heating promotes gradual crystallisation and growth of the MgO nanoparticles, and concomitant loss of Mg(OH)(OCH3). In situ DRIFTS confirms the residual precursor and surface carbonate begin to decompose above 300 °C, while in situ XPS shows these morphological changes are accompanied by the disappearance of surface hydroxyl/methoxide species and genesis of O- centres which enhance both the surface density and basicity of the resulting stepped and defective MgO nanocrystals. The catalytic performance in tributyrin transesterification with methanol is directly proportional to the density of strong surface base sites. © 2010 Elsevier B.V. All rights reserved.
