Self-neglect and adult safeguarding: findings from research
This report was commissioned by the Department of Health (DH) and examines the concept of self-neglect. The relationship between self-neglect and safeguarding in the UK is a difficult one, partly because the current definition of abuse specifies harmful actions by someone other than the individual at risk. Safeguarding Adults Boardsâ policies and procedures commonly contain no reference to self-neglect; occasionally they explicitly exclude it or set criteria for its inclusion
The perceptions of people who neglect themselves have not been extensively researched, but where they have, emerging themes are pride in self-sufficiency, connectedness to place and possessions and behaviour that attempts to preserve continuity of identity and control. Traumatic histories and life-changing effects are also present in individualsâ own accounts of their situation.
Self-neglect is reported mainly as occurring in older people, although it is also associated with mental ill health. Differentiation between inability and unwillingness to care for oneself, and capacity to understand the consequences of oneâs actions, are crucial determinants of response. Professional tolerance of self-neglect as lifestyle choice is higher than when it accompanies physical/mental impairment. Professionals express uncertainty about causation and intervention
The palmar anhidrotic response in chronic schizophrenia
The palmar anhidrotic response to self-induced stress was investigated in a group of in-patient schizophrenics, a group of out-patient schizophrenics and a group of normal controls. The findings were then related to scores on clinical rating scales measuring the degree of withdrawal and the degree of morbidity both before and during the illness. 2. The control group and the group of outpatients showed normal palmar anhidrotic responses to the stress; the group of in-patients showed a paradoxical increase in the number of active glands immediately after the stress. 3. The basal level of the palmar sweating index was lower in the in-patient group than in the out-patient group and that of the out-patient group was lower than that in the group of normal controls. 4. The findings suggested that schizophrenic patients characterized by high chronicity, high withdrawal and a poor pre-morbid personality are also subject to some degree of automatic disorganization. This study was carried out at Littlemore Hospital, Oxford, and financed by the Rhodes Trust and by the Nuffield Foundation.peer-reviewe
Nanoscale resolution interrogation scheme for simultaneous static and dynamic fiber Bragg grating strain sensing
A combined interrogation and signal processing technique which facilitates high-speed simultaneous static and dynamic strain demodulation of multiplexed ïŹber Bragg grating sensors is described. The scheme integrates passive, interferometric wavelength-demodulation and fast optical switching between wavelength division multiplexer channels with signal extraction via a software lock-in ampliïŹer and fast Fourier transform. Static and dynamic strain measurements with noise ïŹoors of 1 nanostrain and 10 nanostrain/sqrt(Hz), between 5 mHz and 2 kHz were obtained. An inverse analysis applied to a cantilever beam set up was used to characterise and verify strain measurements using ïŹnite element modeling. By providing distributed measurements of both ultahigh-resolution static and dynamic strain, the proposed scheme will facilitate advanced structural health monitoring
Multipliers of embedded discs
We consider a number of examples of multiplier algebras on Hilbert spaces
associated to discs embedded into a complex ball in order to examine the
isomorphism problem for multiplier algebras on complete Nevanlinna-Pick
reproducing kernel Hilbert spaces. In particular, we exhibit uncountably many
discs in the ball of which are multiplier biholomorphic but have
non-isomorphic multiplier algebras. We also show that there are closed discs in
the ball of which are varieties, and examine their multiplier
algebras. In finite balls, we provide a counterpoint to a result of Alpay,
Putinar and Vinnikov by providing a proper rational biholomorphism of the disc
onto a variety in such that the multiplier algebra is not all
of . We also show that the transversality property, which is one
of their hypotheses, is a consequence of the smoothness that they require.Comment: 34 pages; the earlier version relied on a result of Davidson and
Pitts that the fibre of the maximal ideal space of the multiplier algebra
over a point in the open ball consists only of point evaluation. This result
fails for , and has necessitated some changes; to appear in

High-speed interferometric FBG interrogator with dynamic and absolute wavelength measurement capability
A passive, interferometric wavelength demodulation technique has been extended to measure the absolute wavelengths of a multiplexed array of fiber Bragg grating sensors. The scheme retains its original strain resolution of 10 nΔ/â{Hz}. A proof-of-concept interrogation system was able to determine the absolute wavelength of Bragg peaks to within 20 pm (17 ΌΔ). Static and dynamic Bragg grating strains were accurately demodulated in both absolute and relative wavelength measurement modes. This demonstration indicates that interferometric techniques are able to provide absolute, static and dynamic measurements of strain within a single platform
