Processes in an experience-based co-design project with family carers in community mental health
Experience-based co-design (EBCD) is a service design strategy that facilitates collaborative work between professional staff and service users toward common goals. There is a lack of published examples of it in relation to family carer engagement within a mental health context, and little research exploring the mechanisms behind successful implementation.
The aim of this study was to explore the processes that facilitated EBCD with carer involvement. The study adopted a grounded theory–informed approach involving interviews with 16 participants of an existing EBCD project in an English National Health Service (NHS) trust, reflecting multiple stakeholders. EBCD can be thrown off track in two ways: conflict and getting “bogged down.” Leadership by project and design-group leaders could return group cohesion and maintain project momentum. The developed model reflects key processes.
Future research should examine EBCD projects with similar ranges of stakeholders and in contexts with different levels of organizational change
Convergence aspects for sets of measures with divergences and boundary conditions
In this paper we study set convergence aspects for Banach spaces of
vector-valued measures with divergences (represented by measures or by
functions) and applications. We consider a form of normal trace
characterization to establish subspaces of measures that directionally vanish
in parts of the boundary, and present examples constructed with binary trees.
Subsequently we study convex sets with total variation bounds and their
convergence properties together with applications to the stability of
optimization problems
On piezophase effects in mechanically loaded atomic scale Josephson junctions
The response of an intrinsic Josephson contact to externally applied stress
is considered within the framework of the dislocation-induced atomic scale
Josephson effect. The predicted quasi-periodic (Fraunhofer-like)stress-strain
and stress-current patterns should manifest themselves for experimentally
accessible values of applied stresses in intrinsically defected (e.g.,twinned)
crystals.Comment: REVTEX (epsf style), 2 EPS figure
Do galaxies that leak ionizing photons have extreme outflows?
To reionize the early universe, high-energy photons must escape the galaxies
that produce them. It has been suggested that stellar feedback drives galactic
outflows out of star-forming regions, creating low density channels through
which ionizing photons escape into the inter-galactic medium. We compare the
galactic outflow properties of confirmed Lyman continuum (LyC) leaking galaxies
to a control sample of nearby star-forming galaxies to explore whether the
outflows from leakers are extreme as compared to the control sample. We use
data from the Cosmic Origins Spectrograph on the Hubble Space Telescope to
measure the equivalent widths and velocities of Si II and Si III absorption
lines, tracing neutral and ionized galactic outflows. We find that the Si II
and Si III equivalent widths of the LyC leakers reside on the low-end of the
trend established by the control sample. The leakers' velocities are not
statistically different than the control sample, but their absorption line
profiles have a different asymmetry: their central velocities are closer to
their maximum velocities. The outflow kinematics and equivalent widths are
consistent with the scaling relations between outflow properties and host
galaxy properties -- most notably metallicity -- defined by the control sample.
Additionally, we use the Ly\alpha\ profiles to show that the Si II equivalent
width scales with the Ly\alpha\ peak velocity separation. We determine that the
low equivalent widths of the leakers are likely driven by low metallicities and
low H I column densities, consistent with a density-bounded ionization region,
although we cannot rule out significant variations in covering fraction. While
we do not find that the LyC leakers have extreme outflow velocities, the low
maximum-to-central velocity ratios demonstrate the importance of the
acceleration and density profiles for LyC and Ly\alpha\ escape. [abridged]Comment: 17 pages, 8 Figures. Accepted for publication in Astronomy &

Counselling in primary care : a systematic review of the evidence
Primary objective: To undertake a systematic review which aimed to locate, appraise and synthesise evidence to obtain a reliable overview of the clinical effectiveness, cost-effectiveness and user perspectives regarding counselling in primary care.
Main results: Evidence from 26 studies was presented as a narrative synthesis and demonstrated that counselling is effective in the short term, is as effective as CBT with typical heterogeneous primary care populations and more effective than routine primary care for the treatment of non-specific generic psychological problems, anxiety and depression. Counselling may reduce levels of referrals to psychiatric services, but does not appear to reduce medication, the number of GP consultations or overall
costs. Patients are highly satisfied with the counselling they have received in primary care and prefer counselling to medication for depression.
Conclusions and implications for future research: This review demonstrates the value of counselling as a valid
choice for primary care patients and as a broadly effective therapeutic intervention for a wide range of generic psychological conditions presenting in the primary care setting. More rigorous clinical and cost-effectiveness trials are needed together with surveys of more typical users of primary care services
Adiabatic transfer of light in a double cavity and the optical Landau-Zener problem
We analyze the evolution of an electromagnetic field inside a double cavity
when the difference in length between the two cavities is changed, e.g. by
translating the common mirror. We find that this allows photons to be moved
deterministically from one cavity to the other. We are able to obtain the
conditions for adiabatic transfer by first mapping the Maxwell wave equation
for the electric field onto a Schroedinger-like wave equation, and then using
the Landau-Zener result for the transition probability at an avoided crossing.
Our analysis reveals that this mapping only rigorously holds when the two
cavities are weakly coupled (i.e. in the regime of a highly reflective common
mirror), and that, generally speaking, care is required when attempting a
hamiltonian description of cavity electrodynamics with time-dependent boundary
conditions.Comment: 24 pages, 18 figures. Version 2 includes a new section (Sec. VIII) on
the regimes of validity of the Schroedinger-like equations and also of the
adiabatic approximation, together with a new figure (Fig. 10). The discussion
section (Sec. XI) has also been enhance
