CCall-Healthy and Successful Work in Call Centres

Benninghoven A., Bindzius F., Braun D., Cramer J., Ellegast R., Flowerday U., Genz A., Heyden T., Pfeiffer W., Schittly D., Schweer R., Stamm R.

Call centre workplaces are in many ways a challenge to occupational health and safety. The occupation itself can be described as an information technology-supported, communication-intensive form of work with often unusual working hours and a high rate of part-time employment. Data on the employee turnover as well as absenteeism related to occupational disability is quite contradictory. Occupational safety and its proponents still have to find new ways into the corporate structures and cultures of this relatively new and rapidly growing branch of industry. In a 2-year research and development project, using a holistic approach and under consideration of all the relevant disciplines, call centre workplaces were studied, and organisational measures were developed and field tested by putting them into practice. Practical help was developed for a sustainable strategy for successful and healthy work in call centres.

Pion entropy and phase space density in RHIC collisions

Cramer J.

Nukleonika

2004

Vol. 49,suppl.2

41-44

We present the source-averaged phase space density , the entropy per particle S pi/N pi, and the total pion entropy per participant (dSpi/dy)/Np extracted at midrapidity in six momentum intervals and seven centrality intervals, for pions produced in sNN = 130 GeV Au+Au collisions at RHIC. These are inferred from measured pi- momentum spectra and HBT correlation analysis of pion data from the STAR detector. The source-averaged pion phase space density reaches a plateau with centrality and is significantly larger than that observed for sNN = 17 GeV Pb+Pb central collisions at the CERN SPS. The entropy per particle Spi/Npi is relatively low, approaching the Landau limit. The total pion entropy per participant (dSpi/dy)/Np is about 6.5 š 0.1, independent of centrality, suggesting that there is no per-participant increase in initial entropy production with increasing collision centrality.
