 +   <hidden TTP02-26  The Impact of $\sigma(e^+e^-\to \mbox{hadrons})$ Measurements at Intermediate Energies on the Parameters of the Standard Model > We discuss the impact of precision measurements of $\sigma(e^+e^-\to 
 + \mbox{hadrons})$  
 + in the center-of-mass range between 3 and 12~GeV, including improvements 
 + in the electronic widths of the narrow charmonium and bottonium resonances, 
 + on the determination of parameters of the Standard Model.  
 + In particular we discuss the impact of potential improvements on the  
 + extraction of the strong coupling constant $\alpha_s$, on the evaluation of  
 + the hadronic contributions to the electromagnetic coupling $\alpha(M_Z)$, and 
 + the determination of the charm and bottom quark masses.
