An overview is provided of the manner in which hydrodynamic and hullform-related design considerations were addressed in the development of the BAE SYSTEMS team’s design proposal for the UK Future Aircraft Carrier (CVF). It also outlines how broader design considerations such as aviation, survivability and supportability requirements influenced these aspects of the design. A summary is also provided of some of the more detailed requirements development, option assessment and performance evaluation work that has been undertaken. The aircraft carrier designs discussed in this paper correspond to the BAE SYSTEMS team’s final design submission as it stood in January 2003, at the time it was discontinued by the UK Ministry of Defence, in favour of the rival Thales / BMT team design that has since been developed into the UK Royal Navy’s new ‘Queen Elizabeth’ class aircraft carrier. This final BAE SYSTEMS design submission consisted of two distinct design variants - one configured to operate a CTOL-based air group, the other configured to accommodate a STOVL air group. Both variants were based on a common ‘core’ ship design. The discussion presented in this paper is applicable to both variants.

Both variants were based on a common ‘core’ ship design. The discussion presented in this paper is applicable to both variants. This paper was originally written for presentation at the June 2003 Royal Institution of Naval Architects ‘Warships 2003 - Air Power at Sea’ Conference. However, it was withheld from publication at the request of the UK Ministry of Defence, due to sensitivity surrounding the UK Aircraft Carrier project at that time. Following re-appraisal in June 2016, the UK Ministry of Defence has now authorised publication of this paper in full. The paper is presented here in its original (2003) form, with Section 2 added to provide historical perspective (given the passage of time).

Improving the performance of idlers is paramount to the performance of the conveyor system in various industries since belt conveyors can be many kilometers in length and consequently there are a huge number of rollers in use. The key intention of this work is the development of a light-weight composite idler roller. Critical design considerations are strength-to-weight ratio and performance. Most importantly, the design must reduce the weight of the roller as compared to standard steel rollers. The final design provides a significant reduction in weight of about 47 % over that of traditional steel rollers of a similar size.

In the last decade, there has been a surge in the number of academic research groups and commercial companies exploiting naturally occurring cosmic-ray muons for imaging purposes in a range of industrial and geological applications. Since 2009, researchers at the University of Glasgow and the UK National Nuclear Laboratory (NNL) have pioneered this technique for the characterization of shielded nuclear waste containers with significant investment from the UK Nuclear Decommissioning Authority and Sellafield Ltd. Lynkeos Technology Ltd. was formed in 2016 to commercialize the Muon Imaging System (MIS) technology that resulted from this industry-funded academic research. The design, construction and performance of the Lynkeos MIS is presented along with first experimental and commercial results. The high-resolution images include the identification of small fragments of uranium within a surrogate 500-litre intermediate level waste container and metal inclusions within thermally treated GeoMelt® R&D Product Samples. The latter of these are from Lynkeos' first commercial contract with the UK National Nuclear Laboratory. The Lynkeos MIS will be deployed at the NNL Central Laboratory facility on the Sellafield site in Summer 2018 where it will embark upon a series of industry trials. This article is part of the Theo Murphy meeting issue ‘Cosmic-ray muography’.

Farm Livestock

The role of stockmanship in relation to the wellbeing of farm animals has been emphasised in the UK Codes of Recommendations for the Welfare of Farm Livestock (MAFF, 1983). Moreover, previous research work has demonstrated important effects of good and bad stockmanship not only on welfare but also on growth, lactational and reproductive performance of pigs and other farm livestock (Hemsworth et al, 1987). There is a need, therefore, to establish the factors which motivate and demotivate stockpeople since the degree of job satisfaction is likely to have a considerable influence on the attitude and performance of stockpeople and on their empathy with the animals in their care. With this objective in mind, a questionnaire was designed to investigate the aspects which could have an influence on the job satisfaction of the stockpeople involved in pig production.

Purpose – This study aims to address how and why do formal key account management (KAM) programmes hinder effective KAM management, and how can the problems of formalization in KAM be overcome. Recent empirical studies have reported an unexpected negative relationship between KAM formalization and performance. Design/methodology/approach – An 18-month (340 days) ethnographic investigation was undertaken in the UK-based subsidiary of a major US sports goods manufacturer. This ethnographic evidence was triangulated with 113 in-depth interviews. Findings – This study identifies how and why managerial reflexivity allows a more effectively combining of formal and post-bureaucratic KAM practices. While formal KAM programmes provide a means to initiate, implement and control KAM, they have an unintended consequence of increasing organizational bureaucracy, which may in the long-run hinder the KAM effectiveness. Heightened reflexivity, including “wayfinding”, is identified as a means to overcome many of these challenges, allowing for reflexively combining formal with post-bureaucratic KAM practices. Research limitations/implications – The thesis of this paper starts a new line of reflexive KAM research, which draws theoretical influences from the post-bureaucratic turn in management studies. Practical implications – This study seeks to increase KAM implementation success rates and long-term effectiveness of KAM by conceptualizing the new possibilities offered by reflexive KAM. This study demonstrates how reflexive skills (conceptualized as “KAM wayfinding”) can be deployed during KAM implementation and for its continual improvement. Further, the study identifies how KAM programmes can be used to train organizational learning regarding KAM. Furthermore, this study identifies how and why post-bureaucratic KAM can offer additional benefits after an organization has learned key KAM capabilities. Originality/value – A new line of enquiry is identified: the reflexive-turn in KAM. This theoretical position allows us to identify existing weakness in the extant KAM literature, and to show a practical means to improve the effectiveness of KAM. This concerns, in particular, the importance of managerial reflexivity and KAM wayfinding as a means to balance the strengths and weaknesses of formal and post-bureaucratic KAM.

Rented Sector

Purpose – The purpose of this paper is to sketch the UK housing backdrop, review the student private rented sector (PRS) and assess the experience of post-graduate university student tenants in the PRS. Design/methodology/approach – A literature review puts the issues of student-PRS responsiveness into context and helps to untangle some UK housing issues. The private sector’s size, growth and performance is assessed by reviewing secondary data. In-depth interviews were then conducted at a regional university campus. Findings – The study confirms accumulating evidence of an unbalanced UK housing market. The study identified four main PRS issues: first, rapid university expansion without accompanying residential construction has sparked rampant PRS growth with, second, quality issues, third, in tight letting market conditions, rented agent service levels fell and fourth, part of the problem is complex PRS management procedures. Research limitations/implications – The research has three noteworthy limitations. First, the macroeconomic analysis integrated secondary research without independent modelling. Second, the views of letting agents, university property managers, planning officers or landlords were not canvassed. Finally, the pilot interviews were geographically restricted. Practical implications – When they expand, universities, local authorities and industry players need to give due consideration to plan for, design and develop quality student accommodation. Over-reliance on the PRS without informed oversight and coordination could undermine student experience and erode long-term UK competitiveness. Social implications – The lack of quality student rented accommodation mirrors a general housing malaise around affordability, polarisation and sustainable “dwelling”. Standards and professionalism in the rented sector is part of the overall quality mix to attract global talent. Originality/value – The preliminary investigation uses mixed-methods to investigate PRS service delivery. It illustrates the interplay between professional property management and wider issues of metropolitan productivity, sustainability and resilience.
