The impact of involvement in mental health research on views about mental health services and service use: findings from a UK survey

Background: Involvement of service users in mental health research, whether predicated on rights-based or instrumentalist arguments, is appropriately understood as a purposive social action likely to have both intended and unintended consequences. Despite rhetoric and some evidence that involvement is a good thing and confers benefits on the people involved, the impact on involved individuals remain underexplored. Aims: To describe the impact of involvement in research on views about mental health services and service use. Method: A cross-sectional survey of service users involved in mental health research across the UK. Data collected from 166 respondents using an online questionnaire were analysed using the framework approach and narratively synthesised. Results: Involvement, through enabling ‘behind the scenes’ access shaped views of service users about services and service use. Increased awareness of challenges and shortcomings of service delivery shifted expectations, commonly empowering service users to proactively engage in treatment. However, for some respondents, disillusionment led to discontinuation of services. Conclusions: Empowerment is a common outcome of involvement but a minority of service users may become critical and drop out of services. People considering involvement in research should be informed about the potential impact on their views and service use and be appropriately supported during involvement. The theory of user involvement needed to support robust examination of process and outcomes must encompass unintended consequences

Strongly Non-Equilibrium Bose-Einstein Condensation in a Trapped Gas

We present a qualitative (and quantitative, at the level of estimates) analysis of the ordering kinetics in a strongly non-equilibrium state of a weakly interacting Bose gas, trapped with an external potential. At certain conditions, the ordering process is predicted to be even more rich than in the homogeneous case. Like in the homogeneous case, the most characteristic feature of the full-scale non-equilibrium process is the formation of superfluid turbulence.Comment: 4 pages, revtex, no figures.

Unit cell of graphene on Ru(0001): a 25 x 25 supercell with 1250 carbon atoms

The structure of a single layer of graphene on Ru(0001) has been studied using surface x-ray diffraction. A surprising superstructure has been determined, whereby 25 x 25 graphene unit cells lie on 23 x 23 unit cells of Ru. Each supercell contains 2 x 2 crystallographically inequivalent subcells caused by corrugation. Strong intensity oscillations in the superstructure rods demonstrate that the Ru substrate is also significantly corrugated down to several monolayers, and that the bonding between graphene and Ru is strong and cannot be caused by van der Waals bonds. Charge transfer from the Ru substrate to the graphene expands and weakens the C-C bonds, which helps accommodate the in-plane tensile stress. The elucidation of this superstructure provides important information in the potential application of graphene as a template for nanocluster arrays.Comment: 9 pages, 3 figures, paper submitted to peer reviewed journa
