Performance and First Physics Results of the SVT Trigger at CDF II

For the first time in a hadron collider, a novel trigger processor, the Silicon Vertex Trigger (SVT), allows to select the long-lived heavy flavor particles by cutting on the track impact parameter with a precision similar to that of the offline reconstruction. Triggering on displaced tracks has enriched the B-physics program by enhancing the B yields of the lepton-based triggers and opened up full hadronic triggering at CDF. After a first commissioning period, the SVT is fully operational, performing very closely to its design capabilities. System performance and first physics results based on SVT selected data samples are presented.Comment: Invited talk at the Workshop on the CKM Unitarity Triangle, IPPP Durham, April 2003 (eConf C0304052). 4 pages LaTeX, 6 eps figure

Strategy formation effects on managerial action: Strategy in the back of your head

This paper examines the interplay between top and middle level managers as strategy-making settles and in subsequent managerial action. It reports on an exploratory case study at a car service company that has an aggressive expansion strategy. The study examines the context and characteristics of the strategy-making process and the specific evolution of fourteen strategic initiatives. Of particular interest was that the interplay between top managers and middle managers was resolved through a legitimizing mechanism. This interplay took place through deliberation and agreement, with extensive participation, and developed into shared views of strategy which provided legitimation. Once settled, strategic initiatives were subsequently developed in harmony with the strategic intent. This agreement provided guidance to carry out strategic initiatives and was a source of resilient strategic conversation. From analysis of the case, a model presenting how strategic intent interacts with the creation of strategic initiatives is presented. This model aims at overcoming the mutually exclusive bottom-up and top-down sources of influence, integrating both in a process model.Strategy-making; middle management; top management; managerial action;
