The Public Accounts Committee of the House of Commons

This chapter evaluates the Public Accounts Committee (PAC) of the House of Commons in light of recent changes to public audit and broader changes across United Kingdom governance. Structural and organisational features are analysed, as are working practices and relationships. The analyses confirm that the PAC remains a key oversight tool to Parliament and that its profile has increased under the leadership of its first directly-elected Chair. Heightened visibility contains risks for a non-partisan committee and the National Audit Office acts as a shield to deflect criticism. Traditional variables used to measure the impact of the PAC are likely to understate the committee’s actual influence

Interagency training to support the liaison and diversion agenda

Background In England and Wales there are an unacceptably large number of people in prison or in contact with the criminal justice system who have mental health issues. Integrated and effective interagency collaboration is required between the criminal justice system and mental health services to ensure early diagnosis, treatment, appropriate sentencing or diversion of these individuals from the criminal justice systems into mental health services. Liaison and diversion schemes are proposed as a means to integrated service provision through positioning mental health professionals within the criminal justice system. These schemes were recommended by the Bradley Report (2009) to be rolled out for all police custody suites and courts by 2014 in a National Diversion Programme. Working within these schemes, at the interface of the criminal justice system and mental health services, has its challenges (Hean et al., 2009) and the workforce from both systems must be prepared to address these. This was recognised by Bradley when he recommended that: “where appropriate, training should be undertaken jointly with other services to encourage shared understanding and partnership working. Development of training should take place in conjunction with local liaison and diversion services (p111; Bradley, 2009). The form this joint training should take is as yet unexplored. We have proposed elsewhere that joint training should equip different agencies and professionals with the skills and knowledge required to collaborate effectively, and not only focus on mental health awareness courses for those in police, prison and courts services (Hean et al. 2011). The criminal justice system and mental health services need to come together to learn about, from, and with each other in interagency training. Aim We present in this report our vision of what this joint interagency training between the criminal justice and mental health services should contain, how it may be delivered and its potential benefits. We explore the receptiveness of professionals from the criminal justice and mental health services to interagency training and explore their perceptions of the challenges to interagency working between the two systems. We focus particularly on one particular dimension: an interagency crossing boundary workshop and its theoretical underpinnings. We explore professionals’ expectations of this type of intervention as well as their perceptions of the knowledge and skills required to deliver the emerging liaison and diversion agenda in general and the content and delivery of interagency training in the future. These findings are synthesized into a series of recommendations and a model of interagency training that will prepare professionals in both agencies to respond to the liaison and diversion agenda more effectively and work collaboratively in the interest of the mentally ill offender. Method A crossing boundary workshop (Engeström, 2001) was delivered in December 2011 to a sample of 52 professionals from a range of non-health professionals associated with criminal justice system (probation, police and courts) and professionals from the mental health system or health domain (learning disability, substance misuse and mental health services). The receptiveness of criminal justice system and mental health service professionals to interagency training was assessed through the Readiness for Interprofessional Learning Scale (Reid et al., 2005) administered to respondents before the workshop. Perceptions of the challenges facing interagency working and the expectations of the workshop were explored through interactive exercises. Professionals from both agencies participated in a series of 6 parallel focus groups to discuss how to prepare the workforce to respond effectively to the liaison/diversion agenda and the constraints they worked under in terms of commissioning, delivering and attending this training. Findings Professionals from both the mental health and criminal justice systems need to build empathic relationships with staff from other agencies. They stressed the importance of actual face-to-face contact between professionals from different agencies to achieve this and saw interagency relationships as being built through increased knowledge of other agencies and the orchestrating of formal facilitated contact between them. They were strongly in favour of interagency training and its contribution to enhanced collaborative competence across the workforce and, in the long term, improved offender mental health. They believed interagency training would develop in the workforce a greater knowledge of other agencies and help them understand other professionals’ roles and responsibilities. They believed interagency training should occur pre-qualification, through into continued professional development and contain a variety of interagency training experiences. Professionals from both systems shared a high level of person centredness in their approach to their practice and stressed the importance of training being grounded and delivered in a real world environment. Participants acknowledged that training opportunities are under threat due to financial and time limitations and that joint commissioning, shared resources and economies of scale must be considered. Recommendations • A training package should be developed to prepare professionals both from the mental health and criminal justice system for the liaison and diversion agenda and integrated service provision. This training must offer a strong interagency component aimed at developing interagency collaboration skills and interagency knowledge. A four-stage training model is proposed in this report. This incorporates pre-registration or undergraduate training for trainee professionals in the mental health services and criminal justice system, general awareness training, interagency training for continuing professional development and the development of interagency reflective practice opportunities. This model may be supplemented by a variety of on-line resources, some of which are described. • These interagency training models should be developed in partnership between universities and local facilitators from within the criminal justice system and mental health services to provide both the theoretical and evidence based rigour associated with developing collaborative practice curricula alongside the real world contextual knowledge required of these programmes. • In the long term, interagency training should be delivered in practice by practitioners to ensure the continued validity and sustainability of these programmes. Training should be sensitive to changes in the workforce due to turnover and the pressures of organisational change. • In times of economic constraint, training should be well targeted at staff and organisations essential to the liaison and diversion agenda. • An interagency commissioning approach will be required to deliver the training package outlined to support the liaison and diversion agenda, and especially if there is to be joint training and sharing of resources

Rapid turnover of hyphae of mycorrhizal fungi determined by AMS microanalysis of C-14

Processes in the soil remain among the least well-characterized components of the carbon cycle. Arbuscular mycorrhizal (AM) fungi are ubiquitous root symbionts in many terrestrial ecosystems and account for a large fraction of photosynthate in a wide range of ecosystems; they therefore play a key role in the terrestrial carbon cycle. A large part of the fungal mycelium is outside the root ( the extraradical mycelium, ERM) and, because of the dispersed growth pattern and the small diameter of the hyphae (<5 micrometers), exceptionally difficult to study quantitatively. Critically, the longevity of these. ne hyphae has never been measured, although it is assumed to be short. To quantify carbon turnover in these hyphae, we exposed mycorrhizal plants to fossil ("carbon-14 - dead") carbon dioxide and collected samples of ERM hyphae ( up to 116 micrograms) over the following 29 days. Analyses of their carbon-14 content by accelerator mass spectrometry (AMS) showed that most ERM hyphae of AM fungi live, on average, 5 to 6 days. This high turnover rate reveals a large and rapid mycorrhizal pathway of carbon in the soil carbon cycle

Improving collaborative practice to address offender mental health: criminal justice and mental health service professionals’ attitudes towards interagency training, current training needs and constraints,

Background Professionals from the mental health and criminal justice system must collaborative effectively to address offender mental health but interprofessional training is lacking. Pedagogical frameworks are required to support the development of training in this new area. Aim To inform this framework this paper explores the readiness of professionals towards interprofessional training and demographic differences in these. It explores expectations of interprofessional training, perceived obstacles to collaborative working, interprofessional training needs and challenges facing delivery. Method A concurrent mixed methods approach collected data from professionals attending a crossing boundaries interprofessional workshop. Data was collected through a combination of the RIPLS questionnaire (n=52), free text questions (n=52) and focus groups (n=6). Findings and Conclusions Mental health and criminal justice professionals’ attitudes towards interprofessional learning were positive (x=17.81; n=43). They did not see their own service as insular (x =4.02; n=44) and reported strong person centredness (x= 6.07; n=43). This suggests professionals are open to the introduction and implementation of future interprofessional training. There were no significant demographic differences in these attitudes. Professionals raised a range of generic curriculum and educator mechanisms in the development of future interprofessional training suggesting the transfer of pedagogical frameworks from established interprofessional programmes into this new arena is feasible. Context specific factors such offender national policy agendas and the challenges of user involvement using mentally ill offenders must be taken into account. Greater clarity on multi versus interprofessional training is still required with this group of professionals. Key words: mental health, offenders, criminal justice, interprofessional training

Parliamentary Oversight and Corruption in the Caribbean: Comparing Trinidad & Tobago and Grenada

Parliamentary oversight is a key determinant of corruption levels. This article presents research findings on parliamentary oversight in two Caribbean countries: Trinidad & Tobago and Grenada. Our results cast doubt on the results of previous research and also indicate that certain facets of ‘the Westminster’ system need to be relaxed, to reflect contextual reality in smaller island economies. Political will to adopt our recommended reforms is critical, but, as in other countries, inertia often dominates the political environment. Until citizens demand that their elected representatives establish various oversight and anti-corruption mechanisms and ensure these mechanisms are free of political influence, the institutions will be ‘window dressing’ and corrupt actions will go undeterred and unpunished

Zinc-blende and wurtzite AlxGa1-xN bulk crystals grown by molecular beam epitaxy

There is a significant difference in the lattice parameters of GaN and AlN and for many device applications AlxGa1-xN substrates would be preferable to either GaN or AlN. We have studied the growth of free-standing zinc-blende and wurtzite AlxGa1-xN bulk crystals by plasma-assisted molecular beam epitaxy (PA-MBE). Thick (similar to 10 mu m) zinc-blende and wurtzite AlxGa1-xN films were grown by PA-MBE on 2-in. GaAs (0 0 1) and GaAs (1 1 1)B substrates respectively and were removed from the GaAs substrate after the growth. We demonstrate that free-standing zinc-blende and wurtzite AlxGa1-xN wafers can be achieved by PA-MBE for a wide range of Al compositions. (C) 2011 Elsevier B.V. All rights reserved

Anomalous elasticity of a cellular tissue vertex model

Vertex models, such as those used to describe cellular tissue, have an energy controlled by deviations of each cell area and perimeter from target values. The constrained nonlinear relation between area and perimeter leads to new mechanical response. Here we provide a mean-field treatment of a highly simplified model: a uniform network of regular polygons with no topological rearrangements. Since all polygons deform in the same way, we only need to analyze the ground states and the response to deformations of a single polygon (cell). The model exhibits the known transition between a fluid/compatible state, where the cell can accommodate both target area and perimeter, and a rigid/incompatible state. We calculate and measure the mechanical resistance to various deformation protocols and discover that at the onset of rigidity, where a single zero-energy ground state exists, linear elasticity fails to describe the mechanical response to even infinitesimal deformations. In particular, we identify a breakdown of reciprocity expressed via different moduli for compressive and tensile loads, implying nonanalyticity of the energy functional. We give a pictorial representation in configuration space that reveals that the complex elastic response of the vertex model arises from the presence of two distinct sets of reference states (associated with target area and target perimeter). Our results on the critically compatible tissue provide a new route for the design of mechanical metamaterials that violate or extend classical elasticity
