Model-independent source imaging using two-pion correlations in (2 to 8)a GeV Au+Au collisions.

We report a particle source imaging analysis based on two-pion correlations in high multiplicity Au+Au collisions at beam energies between 2A and 8A GeV. We apply the imaging technique introduced by Brown and Danielewicz, which allows a model-independent extraction of source functions with useful accuracy out to relative pion separations of about 20 fm. The extracted source functions have Gaussian shapes. Values of source functions at zero separation are almost constant across the energy range under study. Imaging results are found to be consistent with conventional source parameters obtained from a multidimensional Hanburg-Brown-Twiss analysis.

An audit of the application of care aims across the south west Thames region.

Care aims are a means of defining the purpose of intervention of health care. The Malcomess care aims model uses these labels to guide the planning, delivery and outcome measurement of care. Within speech and language therapy (SLT) this involves the use of one of seven labels which clarify and make explicit the purpose of each episode of care undertaken with a client. This relatively simple application has been shown to change the way SLTs work, clarifying expectations of many who use the service. In the South West Thames Region, a project was put in place for SLTs which included undertaking training, audit and support. The outcome of the audit showed that care aims had been adopted across the region in a sufficiently flexible way to meet local needs and offered therapists the tools to reflect on the types of interventions provided to clients.

Downsizing, role demands, and job stress.

This is a cross-sectional study consisting of self-administered survey instruments to measure psychological distress and stress-inducing work demands after 6 months of rumors about an upcoming corporate downsizing event. The workforce consisted predominantly of white males who were married, college-educated, and nonsmokers. Higher stress levels were seen among older, more educated workers, who had longer company tenure. Role boundary problems, noxious physical environments, and company tenure were retained in the final multivariable model predicting distress level. The ongoing time delay for management to implement the threatened layoff and peer rankings for a new job performance appraisal contributed to a decline in worker solidarity because of concerns about career and job security. These uncertainties reduced worker productivity and effective teamwork.
