Resolving agency issues in client-contractor relationships to deliver project success

In our research we seek to explain why some relationships between project client and contractors are managed in such a way that leads to success and others are not. In doing so, we analyze how the relational risk that exists when a client sources a project from an external organization is managed. We view the topic through a lens of agency theory and we use a multiple case study research design, analyzing projects from the construction and clinical research business sectors that had varying degrees of success. We extend knowledge of managing relational risk by developing a framework for resolving agency-related issues to deliver project success. The framework encompasses mechanisms to managing relational risk which we classify in five broad areas: contract, understanding, resources, education and delegation – the CURED framework. These areas reflect both formal and informal mechanisms as described in existing literature

Optical implementation of the wavelet transform by using a bacteriorhodopsin film as an optically addressed spatial light modulator

An optical system utilizing the photoinduced dichroism in a bacteriorhodopsin film has been demonstrated for the optical implementation of wavelet transforms. The dichroism, induced by the image of a wavelet filter on a bacteriorhodopsin film leads to polarization rotation of the Fourier components of an image. The polarization-rotated Fourier components of an input scene are analyzed with a polarizer to give the wavelet transform components. The dichroism is induced with beams whose profiles are determined by wavelet filters in order to perform the optical wavelet transform

Conditions of Success for Earned Value Analysis in Projects

Earned Value Analysis (EVA) is a method that has gained traction in some business sectors to report project progress and help control performance. Yet the literature reports mixed results as to its effectiveness in helping deliver successful projects and, additionally, much of the previous studies on the topic is conceptual in nature focusing on the design of the EVA system. We therefore extend knowledge on EVA by analysing the impact of EVA on the levels of success of two projects that utilised the method. This is done through the prism of agency and organisational justice theories. A framework is proposed of EVA conditions of success, incorporating both design and operational aspects of the EVA system. The framework is used to develop testable propositions that can guide further research into the effects of EVA-based systems on the creation of agency-related characteristics in the project environment that are conducive to project success

Interpreting and estimating the risk of iron failures

Metals and particulates accumulate in the distribution system and are mobilised by hydraulic events which can result in discolouration and exceedance of regulatory standards. Traditional decision tools for targeting preventive work are single parameter, based for example on proportion of unlined iron pipe or the number of customer contacts per district metering area (DMA). We show that this approach is too simplistic and propose a multivariate Decision Tree process, using the Random Under-Sampling ensemble method. The outputs gave a classification of High or Low risk per DMA. Initial findings demonstrate an 80 % success rate in identifying high risk DMAs across the supply area for a UK water company
