RECENT developments in the field of convertible aircraft have shown the practicability of numerous methods of achieving vertical take‐off, combined with forward flight that is largely, or completely, supported by fixed wings. The aerodynamics of aircraft which derive their hovering lift from jet thrust are straightforward since there is no down‐wash to complicate the airflow over the wings; if a rotor is used, however, the wash of the rotor will vary from a relatively minor effect in forward flight to the only source of airflow over the wings in hovering.

THE Mathematical Services Department was formed nearly ten years ago to provide a mathematical and computational service for the Establishment. Its computing equipment now includes two high‐speed electronic digital computers (DEUCE), a Hollerith punched card installation, and a number of small computing instruments of both analogue and digital type.

The use of accessible, portable, mental health crisis information in people with intellectual disabilities has not been previously reported. The purpose of this paper is to explore whether crisis information could be modified to be made accessible and meaningful for people with intellectual disabilities.

Personalized information to help in a mental health crisis was recorded on folded A4 sized sheets that could be carried in a conveniently sized wallet.

Three quarters of the participants carried their crisis information wallets on a daily basis for six months before evaluation. They and their carers expressed positive feedback about them carrying the crisis information. No one carrying the information actually experienced a mental health crisis in the six months follow up period so their usefulness in such crises could not be evaluated. However, they were unexpectedly used in other non‐mental health settings and reported to have been helpful.

The sample size in this was small but the findings suggested that the carrying of crisis information might be a helpful measure for some people with intellectual disabilities. A further, larger scale trial is warranted.

The purpose of this paper is to develop an empirical equation of SRB corrosion based on their metabolic species.

Solution containing SRB metabolic species was simulated using abiotic chemistry approach. Linear polarization technique was used to measure the corrosion rate of X52‐sample in simulated solution containing SRB metabolic products species. The curve obtained from LPR data was then fitted using multiple non‐linear regression method by Minitab 15^® software.

Statistical analysis shows that sulphide and sulphite have significant effect on the X52 corrosion rate.

Using abiotic chemistry approach, an empirical equation that considers SRB metabolic species has been developed. The equation could be used to predict carbon steel corrosion rate by SRB.

The purpose of this paper is to describe the evolution of the field of personality disorder since the publication of “Personality disorder: no longer a diagnosis of exclusion” in 2003.

A review of both the academic literature contained within relevant databases alongside manual searches of policy literature and guidance from the key stakeholders was undertaken.

The academic and policy literature concentrates on treating borderline and antisocial personality disorders. It seems unlikely that evidence will resolutely support any one treatment modality over another. Criticism has arisen that comparison between modalities misses inter and intra patient heterogeneity and the measurement of intervention has become conflated with overall service design and the need for robust care pathways. Apparent inconsistency in service availability remains, despite a wealth of evidence demonstrating the availability of cost-effective interventions and the significant inequality of social and health outcomes for this population.

The inclusion of heterogeneous sources required pragmatic compromises in methodological rigour.

This paper charts the recent developments in the field with a wealth of wide-ranging evidence and robust guidance from institutions such as NICE. The policy literature has supported the findings of this evidence but current clinical practice and what patients and carers can expect from services remains at odds. This paper lays bare the disparity between what we know and what is being delivered. The authors argue for the need for greater research into current practice to inform the setting of minimum standards for the treatment of personality disorder.

The concept of recovery is well accepted internationally as a guiding vision for mental health services. The purpose of this paper is to highlight the challenges faced by in-home psychiatric support workers in implementing this vision in their work with clients with severe psychiatric disability.

The findings reported here are based on interviews with 27 support workers and ten managers of organisations providing support services. These were collected as part of evaluations of two supported housing programmes carried out between 2010 and 2011.

Challenges faced by support workers coalesced around two areas: first, balancing the need to provide care with the need to promote autonomy and second, developing an effective working relationship while working mainly within a clients’ home.

These challenges for support workers highlight tensions within the recovery vision that are not easily resolved. To ensure high quality, recovery-oriented care services are provided, support workers need access to training courses that focus on challenging areas of this work and should be provided with regular professional supervision.

Existing literature on support workers has generally focused on the nature of the role and support worker interactions with other health workers. In this paper, the authors highlight difficulties faced by support workers in implementing the vision of recovery in their work. The paper provides important information for policy makers and managers who are designing service delivery systems that aim to promote recovery.

Support workers who provide in‐home support to people with psychiatric disability are becoming a significant part of the mental health workforce. Research is needed to establish the optimum level and content of training they need to effectively carry out their role.

This paper reports on this paper is to draw on the results of a survey of 104 support workers and interviews with 18 support workers and eight managers in Queensland, Australia, who provide in‐home support for people with psychiatric disability. The authors describe the training undertaken by these workers and their perceptions of the adequacy of this training in relation to the challenges of their work.

The majority of support workers felt they had adequate training, though many expressed the desire to know more about mental illness symptoms, medications and the concept of recovery. Support workers nominated motivating their clients and managing challenging behaviour as the most difficult aspect of the job. Future training offered to these workers needs to focus on increasing knowledge about mental illness and the concept of recovery, and supporting them in their work with clients who have low levels of motivation and/or challenging behaviours. Access to professional supervision may also be of benefit.

This paper adds to knowledge about the training needs of support workers who provide in‐home support to people with psychiatric disability. These findings will be useful for practitioners and decision makers who are considering the training needs of this group.

The purpose of this paper is to present the findings of a discussion between people who use crisis services and academics about the development of a mental health digital technology app.

The approach is underpinned by participatory methods that centralise the voice of lived experience in the development or delivery of mental health responses.

The people who contributed to the conversation identified that the app may reflect a recovery approach to mental health whilst also supporting self-management. The app design was a central repository with links to other apps for self-monitoring or interventions.

The app was designed with people with lived experience with an explicit aim to understand what people with lived experience would want from a mental health digital technology.

The purpose of this paper is to study four cases of the adoption of co-production and compare them according to the type of user involvement, contextual factors and the organizational structure.

In total, 30 interviews were conducted in four mental health organizations which are implementing co-production in the North of Italy. Interviews were conducted with clinicians, nurses, patients and family members. The data collected was triangulated with further sources and official documents of organizations. The results have been compared by means of a validated international framework (IAP2) regarding the contextual factors and the level of co-production adopted.

The adoption of co-production in the four cases differs by the activities implemented and how organizations involve informal actors. It seems to be influenced by the contextual factors specific to each organization: power, professionals’ opinions and leadership. Organizations whose practitioners and leaders are willing to distribute their power and value informal actors’ opinions seem to facilitate the systematic involvement of users. Overall, the results highlight the importance of considering contextual factors when evaluating and describing co-production activities.

This paper contributes to describing how mental health organizations are implementing co-production. It examines the influence of contextual factors on the type of co-production adopted.

The purpose of this paper is to explore the discourses which exist around the alleviation of mental distress, from the different perspective of mental health professionals and service users. It then looks at the use of “practice-based evidence” as a means of bringing together these two diverging discourses.

Literature on the discourses which exist around the cause and treatment of mental distress, from the perspective of professionals and service users, is first explored. Differences between these two discourses are identified, as are theoretical and practical limitations of current professional diagnostic and treatment paradigms. Finally the use of practice-based evidence as a means of bridging the gap between these two discourses is outlined.

This paper highlights marked differences between the discourse which exists for professionals, and that for service users, around alleviating mental distress. The use of practice-based evidence is explored, not only as a means of bringing these two varying discourses together, but also as a tool which could help to improve treatment outcome in a way which is more inclusive of service users and fits with both empiricism and a broader recovery ethos.

This paper applies a “practice-based evidence” approach to bringing together the divergent perspectives regarding mental health of service providers and users. In doing so it provides a practical and pragmatic approach to true collaborative working.
