GE Jet Engine Bracket Challenge: A Case Study in Sustainable Design

Open crowdsourcing competitions can provide a large repository of data which can be used to achieve more sustainable product designs. This study looks at the recent General Electric challenge, a competition to minimize the mass of a titanium jet engine lifting bracket, to illustrate the benefits that can be accrued. In the light of current literature the benefits and challenges of crowdsourcing have been considered. Samples of the entrants to the challenge have been compared to identify critical characteristics for interpreting sustainable designs for additive manufacture. Focusing initially on topological optimisation and orientation of the additive manufacture build, critical features have been highlighted. The availability of many CAD designs has been most useful and has potential for future developments. Crowdsourcing as an innovation approach can also be beneficial for both companies and individuals particularly if the entries are open sourc

Zombies, time machines and brains: Science fiction made real in immersive theatres

Critical thought on immersive theatres is gathering in pace with many arguments centred on explorations of audience/performer interaction and the unique relationship these theatres create. Within this paper I look beyond these debates in order to consider the implications of immersive theatres within contemporary culture, with the aim of furthering the ways in which immersive theatres are presently being framed and discussed. Theatre and science fiction have shared a somewhat limited relationship compared to their burgeoning usage within other forms of entertainment. This paper focuses on how the conceits of science fiction are being staged within this theatrical setting. Primary focus is given to Punchdrunk's… and darkness descended (2011) and The Crash of the Elysium (2011–2012). This is considered alongside The Republic of the Imagination's (TROTI) Cerebellium (2012–14), an original narrative created for the performance which has been subsequently developed over a three-year period to date. This discussion is presented and framed through my personal experience as both a performer in Cerebellium and (later) as audience member. The particular use of dystopian narratives and alternate worlds is given consideration, with reflection on the way these works destabilize and call into question the audience's sense of self either through their ability to survive or understand their sense of self. By making evident the spectrum of practice, I endeavour to delve further into identifying and de-mystifying immersive theatres and their differences to conventional theatre

Assessment of child or young person with a possible eating disorder

Assessing young people with possible eating disorders can be complex for a variety of reasons, including managing confidentiality and risk (for example, a young person not wanting their parent to be involved, or a parent presenting with concerns about their child), the young person or parent not being aware of the severity of the illness, and difficulty in knowing how questions can be sensitively phrased. This Practice Pointer will offer advice on building therapeutic relationships in consultation with a child or young person, and with their parent(s), what information to gather and how to do so sensitively, and how to discuss the role of the parent or carer in treatment. We recommend that it is read alongside the accompanying Clinical Update for detailed notes on examination, investigations, when to refer, and risk. The advice is based on expert experience. We use the female pronoun throughout as eating disorders are more prevalent in females, but it should be noted that they can and do also occur in males

Digital Technology Use and Mental Health Consultations:Survey of the Views and Experiences of Clinicians and Young People

BackgroundDigital technologies play an increasingly important role in the lives of young people and have important effects on their mental health. ObjectiveWe aimed to explore 3 key areas of the intersection between digital technology and mental health: the views and experiences of young people and clinicians about digital technology and mental health; implementation and barriers to the UK national guidance recommendation—that the discussion of digital technology use should form a core part of mental health assessment; and how digital technology might be used to support existing consultations. MethodsTwo cross-sectional web-based surveys were conducted in 2020 between June and December, with mental health clinicians (n=99) and young people (n=320). Descriptive statistics were used to summarize the proportions. Multilinear regression was used to explore how the answers varied by gender, sexuality, and age. Thematic analysis was used to explore the contents of the extended free-text answers. Anxiety was measured using the Generalized Anxiety Disorder Questionnaire-7 (GAD-7). ResultsDigital technology use was ubiquitous among young people, with positive and negative aspects acknowledged by both clinicians and young people. Negative experiences were common (131/284, 46.1%) and were associated with increased anxiety levels among young people (GAD-7 3.29; 95% CI 1.97-4.61; P<.001). Although the discussion of digital technology use was regarded as important by clinicians and acceptable by young people, less than half of clinicians (42/85, 49.4%) routinely asked about the use of digital technology and over a third of young people (48/121, 39.6%) who had received mental health care had never been asked about their digital technology use. The conversations were often experienced as unhelpful. Helpful conversations were characterized by greater depth and exploration of how an individual’s digital technology use related to mental health. Despite most clinicians (59/83, 71.1%) wanting training, very few (21/86, 24.4%) reported receiving training. Clinicians were open to viewing mental health data from apps or social media to help with consultations. Although young people were generally, in theory, comfortable sharing such data with health professionals, when presented with a binary choice, most reported not wanting to share social media (84/117, 71.8%) or app data (67/118, 56.8%) during consultations. ConclusionsDigital technology use was common, and negative experiences were frequent and associated with anxiety. Over a third of young people were not asked about their digital technology use during mental health consultations, and potentially valuable information about relevant negative experiences on the web was not being captured during consultations. Clinicians would benefit from having access to training to support these discussions with young people. Although young people recognized that app data could be helpful to clinicians, they appeared hesitant to share their own data. This finding suggests that data sharing has barriers that need to be further explored

Comorbidity of self-harm and disordered eating in young people:Evidence from a UK population-based cohort

BACKGROUND: Self-harm and eating disorders are often comorbid in clinical samples but their co-occurrence in the general population is unclear. Given that only a small proportion of individuals who self-harm or have disordered eating present to clinical services, and that both self-harm and eating disorders are associated with substantial morbidity and mortality, it is important to study these behaviours at a population level. METHODS: We assessed the co-occurrence of self-harm and disordered eating behaviours in 3384 females and 2326 males from a UK population-based cohort: the Avon Longitudinal Study of Parents and Children (ALSPAC). Participants reported on their self-harm and disordered eating behaviours (fasting, purging, binge-eating and excessive exercise) in the last year via questionnaire at 16 and 24 years. At each age we assessed how many individuals who self-harm also reported disordered eating, and how many individuals with disordered eating also reported self-harm. RESULTS: We found high comorbidity of self-harm and disordered eating. Almost two-thirds of 16-year-old females, and two-in-five 24-year old males who self-harmed also reported some form of disordered eating. Young people with disordered eating reported higher levels of self-harm at both ages compared to those without disordered eating. LIMITATIONS: We were not able to measure whether participants identified their disordered eating as a method of self-harm. CONCLUSIONS: Self-harm and disordered eating commonly co-occur in young people in the general population. It is important to screen for both sets of difficulties to provide appropriate treatment

Measuring practice leadership in supported accommodation services for people with intellectual disability: Comparing staff-rated and observational measures

Background Studies incorporating staff-rated or observational measures of practice leadership have shown that where practice leadership is stronger, active support is better implemented. The study aim was to compare measures of practice leadership used in previous research to determine the extent of their correspondence. Method A subset of data from a longitudinal study regarding 29 front-line managers working across 36 supported accommodation services in Australia was used. An observed measure of practice leadership, based on an interview and observation of a front-line manager, was compared with ratings of practice leadership completed by staff. The quality of active support was rated after a 2-hour structured observation. Results Correlations between staff-rated and observed measures were non-significant. Only the observed measure was correlated with the quality of active support. Conclusions This study provides evidence to support using an observational measure of practice leadership rather than reliance on staff ratings
