Can consumer research panels form an effective part of the cancer research community?

The North Trent Cancer Research Network’s Consumer Research Panel (NTCRN CRP) was established in December 2001 by the Academic Unit of Supportive Care at the University of Sheffield. In three years, the CRP has succeeded in nurturing a climate of sustainable consumer involvement within the NTCRN and this has become embedded in the culture of the network. Furthermore, the panel have championed a sustainable development of consumer involvement in health and social care research by testing new ground and forging a new way of working between health professionals and patients and carers. The CRP model has been held up as an example to other cancer networks, with new panels being set up around the country to emulate its success. This paper describes the Sheffield model of patient and public involvement and using the eight key principles of successful consumer involvement in research, identified in a recent paper by Telford et al (2003), provides a useful framework for analysing the work of the Panel. This demonstrates how consumers and professionals can inform each other to work constructively and synergistically to achieve impressive research results. The need for measurable outcomes to assess the impact and effect of consumer involvement is finally explored

The importance of planetary rotation period for ocean heat transport

The climate, and hence potential habitability, of a planet crucially depends on how its atmospheric and oceanic circulation transports heat from warmer to cooler regions. However, previous studies of planetary climate have concentrated on modelling the dynamics of their atmospheres whilst dramatically simplifying the treatment of the oceans, which neglects or misrepresents the effect of the ocean in the total heat transport. Even the majority of studies with a dynamic ocean have used a simple so-called aquaplanet having no continental barriers, which is a configuration which dramatically changes the oceanic dynamics. Here the significance of the response of poleward ocean heat transport to planetary rotation period is shown with a simple meridional barrier – the simplest representation of any continental configuration. The poleward ocean heat transport increases significantly as the planetary rotation period is increased. The peak heat transport more than doubles when the rotation period is increased by a factor of ten. There are also significant changes to ocean temperature at depth, with implications for the carbon cycle. There is strong agreement between the model results and a scale analysis of the governing equations. This result highlights the importance of both planetary rotation period and the ocean circulation when considering planetary habitability

Mertens' theorem for toral automorphisms

A dynamical Mertens' theorem for ergodic toral automorphisms with error term O(N^{-1}) is found, and the influence of resonances among the eigenvalues of unit modulus is examined. Examples are found with many more, and with many fewer, periodic orbits than expected

Trace gas transport in the subsurface of Mars

The ExoMars Trace Gas Orbiter (TGO) will have the capability of detecting and characterizing a broad suite of trace gases in the atmosphere of Mars. Interpreting the results of this mission will require an understanding of how these trace gases are transported from their sources, which may be deep underground, to the atmosphere. Here we present results of modeling designed to measure the timescales of release from putative subsurface methane sources. These transport timescales are far longer than mixing times in the atmosphere and could be up to 10 million years

Phase 2 of the Multiple Provider Employment Zones Qualitative Study, DWP Research Report 399

This report presents the findings of a qualitative study of the operation and impact of the Multiple Provider Employment Zone (MPEZ) initiatives that have operated in four cities (London, Birmingham, Liverpool and Glasgow) since 20041. The study builds on earlier work by Cambridge Policy Consultants (Hirst et al. 2006), which concentrated on issues related to the early establishment of the MPEZ initiative and the initial experiences of Providers, Jobcentre Plus districts and customers. The Phase 2 research took place approximately one year on from the Phase 1 study and focused on tracking developments in the operation of MPEZ as the initiative became more established. The study involved interviews with EZ Providers (managers and Advisers), Jobcentre Plus representatives (managers and Advisers) and customers (young people (aged 18-24) claiming Jobseeker’s Allowance (JSA), who would otherwise have returned to New Deal for Young People (NDYP)2, lone parents receiving Income Support and early entrants – see section 1.6 for full details). In order to gain a wider perspective, researchers also spoke to representatives of organisations that have employed MPEZ participants and a number of stakeholder organisations with a broad interest in local labour market policies and programmes in the MPEZ areas. In total, the research involved interviews or group discussions with over 300 individuals, providing a range and depth of qualitative information that allows a detailed picture to be established of the way that MPEZs developed between mid- 2005 and mid-2006, including the experiences of employers and the labour market destinations of MPEZ participants. A central issue addressed in the research and in this report is the ‘multiple’ element of the initiative and the value that is added through the existence of more than one Provider in each MPEZ area. Questions of allocation, choice, specialisation, competition and innovation are considered from the perspectives of Providers, Jobcentre Plus, customers, employers and stakeholders and the final sections present some conclusions and issues for consideration in relation to these topics

Human subjective response to steering wheel vibration caused by diesel engine idle

This study investigated the human subjective response to steering wheel vibration of the type caused by a four-cylinder diesel engine idle in passenger cars. Vibrotactile perception was assessed using sinusoidal amplitude-modulated vibratory stimuli of constant energy level (r.m.s. acceleration, 0.41 m/s(2)) having a carrier frequency of 26 Hz (i.e. engine firing frequency) and modulation frequency of 6.5 Hz (half-order engine harmonic). Evaluations of seven levels of modulation depth parameter m (0.0, 0.1, 0.2, 0.4, 0.6, 0.8, and 1.0) were performed in order to define the growth function of human perceived disturbance as a function of amplitude modulation depth. Two semantic descriptors were used (unpleasantness and roughness) and two test methods (the Thurstone paired-comparison method and the Borg CR-10 direct evaluation scale) for a total of four tests. Each test was performed using an independent group of 25 individuals. The results suggest that there is a critical value of modulation depth m = 0.2 below which human subjects do not perceive differences in amplitude modulation and above which the stimulus-response relationship increases monotonically with a power function. The Stevens power exponents suggest that the perceived unpleasantness is non-linearly dependent on modulation depth m with an exponent greater than 1 and that the perceived roughness is dependent with an exponent close to unity

Non-abelian dynamics in first-order cosmological phase transitions

Bubble collisions in cosmological phase transitions are explored, taking the non-abelian character of the gauge fields into account. Both the QCD and electroweak phase transitions are considered. Numerical solutions of the field equations in several limits are presented.Comment: 8 pages, 2 figures. Contribution to the CosPA 2003 Cosmology and Particle Astrophysics Symposium. Typos correcte

GaAs-based Self-Aligned Stripe Superluminescent Diodes Processed Normal to the Cleaved Facet

We demonstrate GaAs-based superluminescent diodes (SLDs) incorporating a window-like back facet in a self-aligned stripe. SLDs are realised with low spectral modulation depth (SMD) at high power spectral density, without application of anti-reflection coatings. Such application of a window-like facet reduces effective facet reflectivity in a broadband manner. We demonstrate 30mW output power in a narrow bandwidth with only 5% SMD, outline the design criteria for high power and low SMD, and describe the deviation from a linear dependence of SMD on output power as a result of Joule heating in SLDs under continuous wave current injection. Furthermore, SLDs processed normal to the facet demonstrate output powers as high as 20mW, offering improvements in beam quality, ease of packaging and use of real estate. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
