The Chronic Fatigue Service at East London NHS Foundation Trust recognised and coalesced around its major issue of engaging its service users. Using the systematic approach of quality improvement, and the infrastructure provided within East London NHS FT's quality improvement programme, it tested a number of change ideas which saw a significant reduction in non-attendance at appointments, an in...
sources in print and manuscript command respect. The final two chapters deal with Galvani's publication of his definitive views on animal electricity in 1791 and their reception. Stimulating here is Williams' view that Galvani thought about electricity in anatomical terms (although his model was the Leyden jar) whereas Volta, coming from a different direction, saw it quite otherwise. There are ...
Forty-five women participated in a variant of the social orienting paradigm employed in "Maternal Touch Predicts Attentional Bias Towards Faces in Young Children" (Reece, in press) [1]. On a given trial, they saw a mathematical equation and indicated whether this equation was true or false. Equations were superimposed on face or house distractors. A female experimenter sat next to the participa...
A few decades ago, it was not taken for granted that university staff should be formally and regularly assessed, except when they were candidates for promotion. Most universities saw this as a task that had to be done by peers, with other stakeholders seldom being included in this process. Senior colleagues assessed whether a young colleague was fit to move up in the academic ranks. His or her ...
Recently, an acoustic waveguide sensor based on multiple mode conversion of surface acoustic waves at the solid-liquid interfaces has been introduced for the concentration measurement of binary and ternary mixtures, liquid level sensing, investigation of spatial inhomogenities or bubble detection. In this contribution the sound wave propagation within this acoustic waveguide sensor is visualize...
A Fibre Bragg Grating (FBG) acoustic sensor is used as a receiver for acoustic communications signals. Acoustic transmissions were generated in aluminium and Carbon Fibre Composite (CFC) panels. The FBG receiver was coupled to the bottom surface opposite a piezoelectric transmitter. For the CFC, a second FBG was embedded within the layup for comparison. We show the transfer function, frequency ...
Comparison and reminding have both been shown to support learning and transfer. Comparison is thought to support transfer because it allows learners to disregard non-matching features of superficially different episodes in order to abstract the essential structure of concepts. Remindings promote memory for the individual episodes and generalization because they prompt learners to retrieve earli...
Listeners infer which object in a visual scene a speaker refers to from the systematic variation of the speaker's tone of voice (ToV). We examined whether ToV also guides word learning. During exposure, participants heard novel adjectives (e.g., "daxen") spoken with a ToV representing hot, cold, strong, weak, big, or small while viewing picture pairs representing the meaning of the adjective an...
We study the approximate flavour symmetries imposed on the lepton sector assuming see-saw mechanism as the neutrino mass structure. We apply the symmetry to various neutrino phenomenologies and obtain constraints on neutrino masses and mixings. Typeset using REVTEX [email protected] 1
