Regional Opportunities and Policy Initiatives for New Venture Creation

This paper investigates the determinants of new venture creation across industries and locations for 103 Italian provinces between 1997 and 2003. We allow for differences in regional opportunities across industries and investigate the impact of a range of factors on entrepreneurship in different industries: manufacturing, retailing and wholesaling, hotels and restaurants. Our results show that wage costs deter entry in manufacturing and that regions with industrial districts are characterized by higher start-up rates. Firm entry in commercial sectors appears higher in large cities and areas with strong economic progress. For hotels and restaurants we find that tourism positively influences new firm formation. In terms of policy we do not find a significant effect of recently introduced regional laws promoting new firm formation.venture creation;policy initiatives;Italian provinces

Efficient algorithms for pairing-based cryptosystems

We describe fast new algorithms to implement recent cryptosystems based on the Tate pairing. In particular, our techniques improve pairing evaluation speed by a factor of about 55 compared to previously known methods in characteristic 3, and attain performance comparable to that of RSA in larger characteristics.We also propose faster algorithms for scalar multiplication in characteristic 3 and square root extraction over Fpm, the latter technique being also useful in contexts other than that of pairing-based cryptography

EFFECT OF FATIGUE FROM REPEATED SPRINTS ON HAMSTRING MUSCLE ACTIVATION PATTERNS DURING RUNNING

Hamstring injury has been associated with fatigue-induced reductions in activation levels during running. This study examined neuromuscular changes of the hamstring muscles as a result of fatigue following sprinting in a group of nine team sport athletes. Hamstring muscle activation, lower-limb kinematics and isokinetic eccentric hamstring strength were assessed to examine the effects of fatigue during running at five different sub-maximal speeds. As expected, there were significant increases in both Biceps Femoris (BF) and Semitendinosus (ST) activations with running speed (P \u3c 0.001). After fatigue, BF activation during late swing significantly decreased by an average of 11% (P=0.002). There was evidence in some subjects that ST activity was increased with fatigue but the increase (4%) was non-significant for the group. There was also a tendency for reduced BF activity with fatigue to be more evident at the faster speeds of running. These findings support other evidence in the literature that the lateral hamstrings (BF) are more susceptible to fatigue. In addition, there were signs of compensatory increased ST activation levels in some subjects. These effects lend support to the potential benefit of this neuromuscular assessment of the hamstrings as a useful measure of both performance and recovery
