No full textA collaborative approach to managing sleep problems
No full textIn response to the local need for advice and support for parents of children and young people with
learning disabilities, a structured 3 week sleep clinic was developed by a community team who
targeted a small group of parents and carers and provided individualised sleep care plans. The clinic
was evaluated very positively by parents, resulting in an ongoing sleep clinic programme; and the
procedure has been shared with another Disabled Children's Team. Further evaluation could be
implemented to strengthen findings; however, it may be useful to share these initial findings more
widely with other localities
96-GT-62 COMPRESSOR OFF-DESIGN PERFORMANCE PREDICTION USING AN ENDWALL MODEL
No full textABSTRACT A throughflow method for designing and analysing compressors has to be supplied with loss, deviation, and blockage estimates for every blade row. The earliest methods used empirical correlations for profile loss and deviation, together with an empirical blockage or "work done" factor, and empirical estimates of additional losses near the endwalls. Previous papers by the author have described how to replace the empirical blockage factor and endwall corrections by explicit calculations using a new mathematical model of the endwall phenomena. Those papers illustrated the application of the method near design conditions, using either design profile loss and deviation figures or computations by a viscous-inviscid interaction blade-to-blade method. In order to estimate off-design performance rapidly over the whole operating range, some way of estimating off-design profile loss encl.deviation must be chosen. In this paper, the previously-derived design point loss and deviation figures are retained, and an empirical correlation due to Miller, Wasdell, and Wright is Used to predict the changes in loss and deviation off-design. It is shown by means of sample threedimensional Nat-Stokes computations that the endwall model remains applicable off-design. The method has been tested against two low speed and two high speed compressors, one of each example having controlled-diffusion blading. The low speed compressor characteristic maps are predicted only approximately, but the predicted high speed compressor maps are good. It is widely believed that endwall flow separation can initiate stall or surge. As stall or surge was approached the shape factor of the annulus wall boundary layer at one location rose sharply, but no single stall-predicting value could be found

Where Does the Wage Penalty Bite?
No full textThe literature examining the relationship between body mass index (BMI) and wages has fairly consistently found that BMI has a negative impact on earnings for women, and less (if any) consequences for men. In this paper, we relax the assumption -- largely unquestioned in this research -- that the conditional mean of wages is linear or piecewise linear in body mass index (BMI). Using data from the 1986 and 1999-2005 Panel Study of Income Dynamics, we estimate semi-parametric wage models that allow earnings to vary with BMI in a highly flexible manner. For women, the results show that earnings peak at levels far below the clinical threshold of "obesity" or even "overweight". For men, our main estimates suggest a reasonably flat BMI-wage profile that peaks early in the "overweight" category. However, the results of instrumental variables (IV) models or specifications focusing on long-lags of BMI are more similar to those for women. The findings for females (and the IV estimates for males) suggest that it is not obesity but rather some other factor -- such as physical attractiveness -- that produces the observed relationship between BMI and wages. We also provide non-parametric estimates of the association between BMI and health expenditures, using data from the Medical Expenditure Panel Survey. These cast further doubt on the hypothesis that the wage penalties associated with increasing BMI occur because the latter serve as an index for underlying medical costs.

No full textClimate Blues: or How Awareness of the Human End might re-instil Ethical Purpose to the Writing of History
No full textThe accumulating evidence on the depth and accelerating trajectory of anthropogenic climate change poses the possibility of an early end to human existence as part of a more general biotic extinction. But if that is the case what does that mean for the latter day writing of history? Our response follows two main lines of thought. The first relates to the concept of the ‘Anthropocene’ and the possibilities that it offers historians to reconsider their subject in the light of what earth science is saying about earth history and our particularly recent role in its shaping. From this perspective, while the idea of a reconceptualised history by reference to key geological and other natural historical thresholds would certainly destabilise current academic practice, it might equally galvanise the historical discipline towards recognition of our present biospheric crisis. The second line of thought explores how history writing might contribute to an ethical response in the face of the end and an almost inevitable, accompanying violence, anomie and destruction. Apocalyptic language is eschewed by a progress-centred history. Here we argue that it is exactly the proper recovery of such discarded religiously subversive notions which could assist in the opening up of an alternative space repudiating a bankrupt political-economic system and envisioning instead a millennial social and environmental justice. The writings of Walter Benjamin, among others, offer historical pathfinders for such ideas. Combined with his presentation of an alternative, qualitative ‘Now’ time—thereby reconfiguring Judeo-Christian notions of kairos—such ideas speak both to the urgency for a purposeful, non- violent response to Endtime but also by implication, an ongoing human quest for grace
