Many attempts have been made to overcome problems involved in character recognition which have resulted in the manufacture of character reading machines. An investigation into a new approach to character recognition is described. Features for recognition are Fourier coefficients. These are generated optically by convolving characters with periodic gratings. The development of hardware to enable automatic measurement of contrast and position of periodic shadows produced by the convolution is described. Fourier coefficients of character sets were measured, many of which are tabulated. Their analysis revealed that a few low frequency sampling points could be selected to recognise sets of numerals. Limited treatment is given to show the effect of type face variations on the values of coefficients which culminated in the location of six sampling frequencies used as features to recognise numerals in two type fonts. Finally, the construction of two character recognition machines is compared and contrasted. The first is a pilot plant based on a test bed optical Fourier analyser, while the second is a more streamlined machine d(3signed for high speed reading. Reasons to indicate that the latter machine would be the most suitable to adapt for industrial and commercial applications are discussed.

Juridical Review. Looks at the question of whether an individual shareholder has title to bring an action on the company's behalf in exceptional circumstances, as considered in the cases of Anderson v Hogg and Wilson v Inverness Retail & Business Park Ltd. Examines the difference between English and Scottish law in this area, notwithstanding the reliance on English case law in Scotland due to the small number of Scottish cases decided. Looks at progress towards the reform of company law and the impact it will have on a shareholder's title to sue.

This paper examines the processes of public sector auditing, and its influence in Fiji over the period 1874-2003. Analyses of historical documents indicate that there were four major themes that influenced expansion of traditional auditing into performance auditing. This paper examines these. It also provides insights into the development of accountability practices as a result of changes in the Auditor-General's role. Conclusions drawn from the analysis indicate that traditional public sector auditing in Fiji expanded in accountability terms, possibly driven by public pressure through the media and elected representatives.

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.

The complexity of environments faced by dynamically adaptive systems (DAS) means that the RE process will often be iterative with analysts revisiting the system specifications based on new environmental understanding product of experiences with experimental deployments, or even after final deployments. An ability to trace backwards to an identified environmental assumption, and to trace forwards to find the areas of a DAS's specification that are affected by changes in environmental understanding aids in supporting this necessarily iterative RE process. This paper demonstrates how claims can be used as markers for areas of uncertainty in a DAS specification. The paper demonstrates backward tracing using claims to identify faulty environmental understanding, and forward tracing to allow generation of new behaviour in the form of policy adaptations and models for transitioning the running system. © 2011 ACM.

Interest into the effects of social influence on members of online communities is growing but there is a lack of knowledge about the impact of influential members in online communities on responses to strategy change within the wider community. We explore social influence in responses to strategy change through content analysis of forum posts before and after a change in strategy. Acceptance or non-acceptance of strategy change and subsequent positive and negative behavioural responses online are dependent on individual factors. The details of these behavioural responses to a change in strategy are tabulated and included in a conceptual model to inform decision-makers. Strategy change precipitates a reduction in social influence effects. Non-acceptance of strategy change is associated with competitor advertisement, inflammatory behaviour, offensive behaviour and complaints. This negative behaviour has important ramifications for acceptance of strategy change within the wider community and impacts on the viability of setting up online forums. © 2014 © 2014 Taylor & Francis.

Many innovations are inspired by past ideas in a nontrivial way. Tracing these origins and identifying scientific branches is crucial for research inspirations. In this paper, we use citation relations to identify the descendant chart, i.e., the family tree of research papers. Unlike other spanning trees that focus on cost or distance minimization, we make use of the nature of citations and identify the most important parent for each publication, leading to a treelike backbone of the citation network. Measures are introduced to validate the backbone as the descendant chart. We show that citation backbones can well characterize the hierarchical and fractal structure of scientific development, and lead to an accurate classification of fields and subfields. © 2011 American Physical Society.
