Housing repossessions, evictions and common mental illness in the UK: results from a household panel study

Background: The numbers of housing repossessions and evictions in the UK are increasing. This study investigates whether repossessions and evictions increase the likelihood of common mental illness and examine patterns over time. Methods: Data come from the core longitudinal panel of the British Household Panel Survey (N=12 390) of adults living in private households. Multivariate fixed-effects regression models are used with weighted data. Common mental illness is measured by the 12-item General Health Questionnaire. Results: Housing repossession is associated with an increased risk of common mental illness (adjusted odds ratio 1.61, 95% confidence interval 1.10 to 2.36), whereas eviction from rented property shows no increased risk (0.97, 0.76 to 1.20). The pattern over time shows a clear increase in the years before repossession. Conclusions: Repossession of owned property, although a relatively rare event in the panel, significantly increases the risk of common mental illness immediately after the event. In contrast, eviction from rented property is a more common event but is not associated with an increased risk of common mental illness. This difference in association may be due to losing the security of owned housing and the often transitory nature of the rented housing population

Technological discontinuities, outsiders and social capital: a case study from Formula 1

Purpose – The purpose of this paper is to examine how and why outsiders, rather than incumbents, are able to take advantage of technological discontinuities. Design/ methodology/approach – The paper employs a case study of a single innovation that transformed the technology of Formula 1 motor racing. Findings – The findings show how social capital made up of ‘weak ties’ in the form of informal personal networks, enabled an outsider to successfully make the leap to a new technological regime. Practical implications – The findings show that where new product development involves a shift to new technologies, social capital can have an important part to play. Originality/value – It is widely accepted that radical innovations are often competence destroying, making it difficult for incumbents to make the transition to a new technology. The findings show how the social capital of outsiders can place them at a particular advantage in utilizing new technologies

Power-by-the-hour: the role of technology in reshaping business strategy at Rolls-Royce

There is a recognised trend of manufacturing companies offering not only products, but services and even complete solutions to business problems. Research has highlighted economic, market demand and competitiveness factors as responsible for the re-shaping of business strategies that this has involved. This study analyses the extent to which another factor, technology, has been a significant factor in the switch from product oriented to service oriented strategies. A case study of the aero engine manufacturer Rolls-Royce is used to analyse the impact of technology, which is found to have led manufacturers to re-shape their business strategies. The study finds that developments in one technology in particular, namely digital electronics, have been a powerful enabling factor facilitating the implementation of service strategies. This provided original equipment manufacturers (OEMs) like Rolls-Royce with a competitive advantage relative to conventional service providers, by enabling them to acquire new knowledge management capabilities

Augmented paper applications: Initial user tests of a wireless pattern reader

A handheld pattern reader has been developed to read low visibility conductive patterns on paper. The patterns are formed by masking conductive paper with a non-conductive, printed lacquer. The reader was developed as part of an EU-funded project investigating methods of augmenting paper. Data read from the patterns was used to trigger events in the digital domain. Usability tests were undertaken to investigate the performance of the prototype. Results showed that at this stage of development there was significant variation in performance of the prototype from user to user. Further work is being undertaken to determine the causes of this variability

Space in 150 years: From fantasy through fiction to fact and function

ABSTRACTIn the last century and a half, space has moved from the realm of fantasy to everyday reality. In parallel, the way space has been regarded by the person in the street and the ideas of what access to space might be used for have evolved extraordinarily.</jats:p

Development and characterisation of lithographically printed voltaic cells

This paper reports progress in the fabrication of voltaic cells and batteries via offset lithographic printing. Successful design and manufacture of lithographically printed voltaic cells would facilitate the integration of printed passive components, interconnects and display elements for disposable electronics in low-volume, low weight circuits and systems. The conductive lithographic film (CLF) printing process was developed by Brunel University to fabricate circuit interconnect and various passive components at high speed and low cost. A feasibility study, investigating printed cells based on zinc-carbon electrochemistry, is described. This has resulted in the production of a printed battery able to power a microcontroller-driven LED display system for more than three hours. Further work seeks to improve cell capacity, address manufacturing process issues, and characterise the structures in more detail

Study design and mark-recapture estimates of dispersal: A case study with the endangered damselfly Coenagrion mercuriale

Accurate data on dispersal ability are vital to the understanding of how species are affected by fragmented landscapes. However, three factors may limit the ability of field studies to detect a representative sample of dispersal events: (1) the number of individuals monitored, (2) the area over which the study is conducted and (3) the time over which the study is conducted. Using sub-sampling of mark-release-recapture data from a study on the endangered damselfly Coenagrion mercuriale (Charpentier), we show that maximum dispersal distance is strongly related to the number of recaptured individuals in the mark-release-recapture study and the length of time over which the study is conducted. Median dispersal distance is only related significantly to the length of the study. Spatial extent is not associated with either dispersal measure in our analysis. Previously consideration has been given to the spatial scale of dispersal experiments but we demonstrated conclusively that temporal scale and the number of marked individuals also have the potential to affect the measurement of dispersal. Based on quadratic relationships between the maximum dispersal distance, recapture number and length of study, we conclude that a previous study was of sufficient scale to characterise the dispersal kernel of C. mercuriale. Our method of analysis could be used to ensure that the results of mark-release-recapture studies are independent of levels of spatial and temporal investment. Improved confidence in dispersal estimates will enable better management decisions to be made for endangered species

Comparison of head gaze and head and eye gaze within an immersive environment

For efficient collaboration between participants, eye gaze is seen as being critical for interaction. Teleconferencing systems such as the AcessGrid allow users to meet across geographically disparate rooms but as of now there seems no substitute for face to face meetings. This paper gives an overview of some preliminary work that looks towards integrating eye gaze into an immersive Collaborative Virtual Environment and assessing the impact that this would have on interaction between the users of such a system. An experiment was conducted to assess the difference between users abilities to judge what objects an avatar is looking at with only head gaze being viewed and also with eye and head gaze data being displayed. The results from the experiment show that eye gaze is of vital importance to the subjects correctly identifying what a person is looking at in an immersive virtual environment. This is followed by a description of how the eye tracking system has been integrated into an immersive collaborative virtual environment and some preliminary results from the use of such a system

Virtual reality and its role in removing the barriers that turn cognitive impairments into intellectual disability

Early expectations of the contribution that virtual reality (VR) could make to education far exceeded actual applications. This was largely due to the initial immaturity of the technology and a lack of evidence base on which to base design and utilisation. While the early developments in computer based learning largely concentrated on mainstream education, leaving those with special needs behind, the potential of VR as an educational tool was exploited for those with intellectual disabilities right from the start. This paper describes the empirical evidence that has contributed to the development of educational virtual reality for those with intellectual disabilities: studies on transfer of learning from the virtual to the real world; how teachers might support those using VR; the design of virtual environments and what input/control devices best facilitate use of desktop VR. Future developments and ethical issues are also considered
