Emergency workers' experiences of the use of section 136 of the Mental Health Act 1983: interpretative phenomenological investigation.

AIMS AND METHOD: To explore the experiences of emergency workers dealing with incidents in which section 136 of the Mental Health Act 1983 is invoked by the police. Data from interviews with police officers and ambulance workers in a London locality were subject to interpretative phenomenological analysis. RESULTS: Participants felt they were the first port of call and that training should be improved to help them deal with those experiencing mental health crises in the community. Police participants noted time pressures trying to gain individuals' trust and described section 136 detention as sometimes feeling like a betrayal of the individual. Most participants had negative experiences of admissions to the 136 suite; several suggested ways of improving the admissions system. Several went beyond their expected duties to ensure that distressed individuals were supported before accessing mental healthcare services. CLINICAL IMPLICATIONS: Improving training of emergency workers in dealing with mental health crises would also help with aftercare decision-making. Learning identified from the participants' experiences lends support to collaboration between emergency and mental health services, an important step towards improving the section 136 process so that detainees can access help without unnecessary delay

Validated prediction of weld residual stresses in austenitic steel pipe girth welds before and after thermal ageing, Part 2: modelling and validation

An extensive finite element simulation campaign was undertaken to examine the complete manufacturing history and high temperature thermal ageing of thick-walled girth-welded austenitic steel pipes fabricated from Esshete 1250 austenitic steel. The simulations examined the impacts of prior quenching of pipe material, fabrication of closely adjacent welds, and axial restraint during welding. The simulations considered both simple isotropic and kinematic hardening behaviour, and a large matrix of Lemaitre-Chaboche mixed isotropic-kinematic hardening material constitutive models, with a focus on examining the most accurate evolutionary hardening behaviour for weld metal. High temperature (650°C) service exposure was modelled using an RCC-MR type creep model, and the sensitivity of the predicted relaxation to variability in the model parameters was assessed. The predicted residual stresses were validated using measurements made with the deep hole and incremental deep hole drilling techniques and the contour method

Working parents and workplace flexibility in New Hampshire

This report, a joint effort between the Carsey Institute, UNH Cooperative Extension, and New Hampshire Employment Security, looks at working parents and their job flexibility and the importance it has for families trying to achieve a work-life balance

Design Matters : CBNRM and Democratic Innovation

Community-based natural resource management (CBRNM) aims to realize sustainable management of resources and improvements in livelihood. A central focus is the empowerment of indigenous and local communities through customary or devolved rights to common pool resources. Less attention is given to the extent to which inclusive forms of governance are realized in CBNRM. Democratic innovations are institutions designed explicitly to increase and deepen citizen participation in political decision-making. A number of exemplary cases around the world provide evidence that it is possible to empower citizens in ways that are inclusive and achieve desirable outcomes such as redistribution, recognition of marginalized groups, and improved livelihoods. By clarifying elements of the design of democratic innovations - in particular goods, tasks, mechanisms, and co-design - it is possible to understand how effective forms of participatory governance can be crafted. With careful attention to the endogenous practices of indigenous and local communities and the governance structures imposed by public authorities, CBNRM practitioners can draw on these elements of democratic design to craft forms of inclusive participatory governance that promote sustainable management of resources and improve livelihoods. A program of collaboration between CBNRM and democratic innovations practitioners will contribute to improvements amongst both communities of practice and the communities they serve

Reusable Software Components for Robots Using Fuzzy Abstractions

Mobile robots today, while varying greatly in design, often have a large number of similarities in terms of their tasks and goals. Navigation, obstacle avoidance, and vision are all examples. In turn, robots of similar design, but with varying configurations, should be able to share the bulk of their controlling software. Any changes required should be minimal and ideally only to specify new hardware configurations. However, it is difficult to achieve such flexibility, mainly due to the enormous variety of robot hardware available and the huge number of possible configurations. Monolithic controllers that can handle such variety are impossible to build. This paper will investigate these portability problems, as well as techniques to manage common abstractions for user-designed components. The challenge is in creating new methods for robot software to support a diverse variety of robots, while also being easily upgraded and extended. These methods can then provide new ways to support the operational and functional reuse of the same high-level components across a variety of robots

Episodic Post-Shock Dust Formation in the Colliding Winds of Eta Carinae

Eta Carinae shows broad peaks in near-infrared (IR) JHKL photometry, roughly correlated with times of periastron passage in the eccentric binary system. After correcting for secular changes attributed to reduced extinction from the thinning Homunculus Nebula, these peaks have IR spectral energy distributions (SEDs) consistent with emission from hot dust at 1400-1700 K. The excess SEDs are clearly inconsistent, however, with the excess being entirely due to free-free wind or photospheric emission. One must conclude, therefore, that the broad near-IR peaks associated with Eta Carinae's 5.5 yr variability are due to thermal emission from hot dust. I propose that this transient hot dust results from episodic formation of grains within compressed post-shock zones of the colliding winds, analogous to the episodic dust formation in Wolf-Rayet binary systems like WR140 or the post-shock dust formation seen in some supernovae like SN2006jc. This dust formation in Eta Carinae seems to occur preferentially near and after periastron passage; near-IR excess emission then fades as the new dust disperses and cools. With the high grain temperatures and Eta Car's C-poor abundances, the grains are probably composed of corundum or similar species that condense at high temperatures, rather than silicates or graphite. Episodic dust formation in Eta Car's colliding winds significantly impacts our understanding of the system, and several observable consequences are discussed.Comment: MNRAS accepted; 8 pages, 5 figs, 2 color fig
