‘Without occupation you don't exist’: Occupational engagement and mental illness

This article has been made available through the Brunel Open Access Publishing Fund.This phenomenological study explores the meanings of work for people living with severe and enduring mental health conditions. The participants were three women and seven men who were attending a mental health day centre. Data were collected through up to three depth interviews with each participant over 18 months. The interviews were digitally recorded, transcribed verbatim, and analysed according to phenomenological principles. Two overarching themes were identified. Building and maintaining an occupational identity expressed the ways in which participants used occupations as the building blocks of an evolving identity. Most of the participants wanted to work, and participation in occupations was seen as essential to recovery from mental ill-health. Work and other ways of belonging encapsulated the need to feel connected to others. Many of the participants envisaged working as a way of achieving this. The longitudinal nature of the study facilitated engagement with the developing narratives and exploration of the changes and consistencies in the participants' meaning making about their occupations. Implications for understanding individuals' occupational participation which enhances a sense of self and promotes feelings of belonging are identified

The meaning and experience of work in the context of severe and enduring mental health problems: An interpretative phenomenological analysis

Copyright @ 2013 IOS Press and the Authors.Research into mental health and employment has indicated that work holds multiple meanings for people with mental health problems. This paper reports findings from a phenomenological study which aimed to understand the complexity of these meanings by exploration of the perspectives of one individual who was considering returning to work. Data were gathered through a series of three interviews carried out over a period of 18 months. Three themes were identified – Beliefs and Values about Work, Working with a Mental Health Problem, and Planning for the Future. Analysis and interpretation facilitated understandings of what work represented for the participant. What this study has contributed to the evidence base is a deeper understanding of the multiple meanings of work, and the varied roles that work may play in contributing to meaning and quality of life for people with mental health problems

Distant perturbation asymptotics in window-coupled waveguides. I. The non-threshold case

We consider a pair of adjacent quantum waveguides, in general of different widths, coupled laterally by a pair of windows in the common boundary, not necessarily of the same length, at a fixed distance. The Hamiltonian is the respective Dirichlet Laplacian. We analyze the asymptotic behavior of the discrete spectrum as the window distance tends to infinity for the generic case, i.e. for eigenvalues of the corresponding one-window problems separated from the threshold

Experimental demonstration of a W-band gyroklystron amplifier

The experimental demonstration of a four cavity W-band (93 GHz) gyroklystron amplifier is reported. The gyroklystron has produced 67 kW peak output power and 28% efficiency in the TE011 mode using a 55 kV, 4.3 A electron beam. The full width at half maximum instantaneous bandwidth is greater than 460 MHz, a significant increase over the bandwidth demonstrated in previous W-band gyroklystron amplifier experiments. The amplifier is unconditionally stable at this operating point. Experimental results are in good agreement with theoretical predictions

Stochastic stability versus localization in chaotic dynamical systems

We prove stochastic stability of chaotic maps for a general class of Markov random perturbations (including singular ones) satisfying some kind of mixing conditions. One of the consequences of this statement is the proof of Ulam's conjecture about the approximation of the dynamics of a chaotic system by a finite state Markov chain. Conditions under which the localization phenomenon (i.e. stabilization of singular invariant measures) takes place are also considered. Our main tools are the so called bounded variation approach combined with the ergodic theorem of Ionescu-Tulcea and Marinescu, and a random walk argument that we apply to prove the absence of ``traps'' under the action of random perturbations.Comment: 27 pages, LaTe
