A ‘cut too deep’; creating a context for change in the family and community of practice for the management of self-harm

Self-harm is prevalent in young people in escalating proportions. Research into its causes and treatments is on-going. Significant numbers of young people are treated in primary care without the medical diagnosis of mental health conditions. Whilst most self-harm happens in bedrooms at night, the family and parents in particular are not always involved in the safety and the support planning of their children. The impact of providing parental care in these circumstances is challenging and can be to the detriment of family members’ health too. The account follows a reflexive journey through a multi-agency project, to deliver two outputs – firstly, the improvement of the management of self-harm in the family and community and secondly, the illumination of the developing model of multi-agency work in this Early Help context. These two domains of exploration interweave and alternate through the thesis. Theories from different psychological and therapeutic domains are considered within the Deleuzian philosophical framework to illuminate the processes that distilled the works. The original reported evidence (upon which this reflexive audit is based) employed mixed methodologies, founded in action research, action learning and grounded theory including qualitative data audits of the mental health context and the impact of self- harm according to parents (134 coded cases reviewed), semi-structured interviews with young people in focus groups, case work and case studies, impact of training programmes and workshops for parents measured through questionnaires and on-line surveys, pre and post intervention scaling, semi- structured interviewing and focus groups in the final phase of work.535 participants from the wider network of practice, families and young people participated in the process. The project reported that a family focused approach is important in the management of self-harm and the helping network struggles to work seamlessly around the family. A relational frame, safety planning, social prescribing to Parent Support programmes and Co-ordinated Circles of support interventions assist at the level of the family. Clinical supervision and GP family focused consultation techniques improve the experience of help and support a context for family recovery. The relationships between the helping partners require attention. Project partners value a model of non-hierarchical collaboration underpinned by shared values within a light-touch framework where the ‘lived experience of the family and network’ is at the core of the developing ideas to improve practice. This model of multi-agency working is optimised when learning is at the centre of partner collaboration and when conditions such as stigmatisation, complex issues, risk management and historical difficult relationships with help are present

Development of Bayesian analysis program for extraction of polarisation observables at CLAS

At the mass scale of a proton, the strong force is not well understood. Various quark models exist, but it is important to determine which quark model(s) are most accurate. Experimentally, finding resonances predicted by some models and not others would give valuable insight into this fundamental interaction. Several labs around the world use photoproduction experiments to find these missing resonances. The aim of this work is to develop a robust Bayesian data analysis program for extracting polarisation observables from pseudoscalar meson photoproduction experiments using CLAS at Jefferson Lab. This method, known as nested sampling, has been compared to traditional methods and has incorporated data parallelisation and GPU programming. It involves an event-by-event likelihood function, which has no associated loss of information from histogram binning, and results can be easily constrained to the physical region. One of the most important advantages of the nested sampling approach is that data from different experiments can be combined and analysed simultaneously. Results on both simulated and previously analysed experimental data for the K+Λ channel will be discussed

Thermal power systems small power systems application project: Siting issues for solar thermal power plants with small community applications

The siting issues associated with small, dispersed solar thermal power plants for utility/small community applications of less than 10 MWe are reported. Some specific requirements are refered to the first engineering experiment for the Small Power Systems Applications (SPSA) Project. The background for the subsequent issue discussions is provided. The SPSA Project and the requirements for the first engineering experiment are described, and the objectives and scope for the report as a whole. A overview of solar thermal technologies and some technology options are discussed

Siting Issues for Solar Thermal Power Plants with Small Community Applications

Technologies for solar thermal plants are being developed to provide energy alternatives for the future. Implementation of these plants requires consideration of siting issues as well as power system technology. While many conventional siting considerations are applicable, there is also a set of unique siting issues for solar thermal plants. Early experimental plants will have special siting considerations. The siting issues associated with small, dispersed solar thermal power plants in the 1 to 10 MWe power range for utility/small community applications are considered. Some specific requirements refer to the first 1 MWe engineering experiment for the Small Power Systems Applications (SPSA) Project. The siting issues themselves are discussed in three categories: (1) system resource requirements, (2) environmental effects on the system, and (3) potential impact of the plant on the environment. Within these categories, specific issues are discussed in a qualitative manner. Examples of limiting factors for some issues are taken from studies of other solar systems

The Volatility Trend of Protosolar and Terrestrial Elemental Abundances

We present new estimates of protosolar elemental abundances based on an improved combination of solar photospheric abundances and CI chondritic abundances. These new estimates indicate CI chondrites and solar abundances are consistent for 60 elements. We compare our new protosolar abundances with our recent estimates of bulk Earth composition (normalized to aluminium), thereby quantifying the devolatilization in going from the solar nebula to the formation of the Earth. The quantification yields a linear trend $\log(f) = \alpha\log(T_C) + \beta$, where $f$ is the Earth-to-Sun abundance ratio and $T_C$ is the 50$\%$ condensation temperature of elements. The best fit coefficients are: $\alpha = 3.676\pm 0.142$ and $\beta = -11.556\pm 0.436$. The quantification of these parameters constrains models of devolatilization processes. For example, the coefficients $\alpha$ and $\beta$ determine a critical devolatilization temperature for the Earth $T_{\mathrm{D}}(\mathrm{E}) = 1391 \pm 15$ K. The terrestrial abundances of elements with $T_{C} < T_{\mathrm{D}}(\mathrm{E})$ are depleted compared with solar abundances, whereas the terrestrial abundances of elements with $T_{C} > T_{\mathrm{D}}(\mathrm{E})$ are indistinguishable from solar abundances. The terrestrial abundance of Hg ($T_C$ = 252 K) appears anomalously high under the assumption that solar and CI chondrite Hg abundances are identical. To resolve this anomaly, we propose that CI chondrites have been depleted in Hg relative to the Sun by a factor of $13\pm7$. We use the best-fit volatility trend to derive the fractional distribution of carbon and oxygen between volatile and refractory components ($f_\mathrm{vol}$, $f_\mathrm{ref}$). We find ($0.91\pm 0.08$, $0.09 \pm 0.08$) for carbon and ($0.80 \pm 0.04$, $0.20 \pm 0.04$) for oxygen.Comment: Accepted for publication in Icarus. 28 pages, 12 figures, 5 tables.
