This paper examines the relationship between Australian and world strike activity between 1960 and 1998. Appropriate indices are constructed for which evidence of a long-run equilibrium relation is found between Australian and world strike activity. The evidence suggests Australian and world strike rate indices are cointegrated with a breakpoint in that relation occurring sometime in the very l...

This paper studies symmetries between fixed and floating-strike Asian options and exploits this symmetry to derive an upper bound for the price of a floating-strike Asian. This bound only involves fixed-strike Asians and vanillas, and can be computed simply given one of the many efficient methods for pricing fixed-strike Asian options. The bound coincides with the true price until after the ave...

This paper studies symmetries between fixed and floating-strike Asian options and exploits this symmetry to derive an upper bound for the price of a floating-strike Asian. This bound only involves fixed-strike Asians and vanillas, and can be computed simply given one of the many efficient methods for pricing fixed-strike Asian options. The bound is exact until after the averaging has begun and ...

occurred at 1.5 to 2.0 cm (Fig. 1). Strike success was similar when compared to prey number remaining, indicating that earlier predation events did not influence predation success. Juvenile toadfish are effective short-range ambush predators. At strike distances between 0 and 1.5 cm they strike successfully 76.2% of the time. But between 1.5 and 2.0 cm, strike success is mixed, and it continues...

Introduction: Ridges are the most common linear and tectonic surface features on Europa [1,2,3,4] and apparent lateral offsets are often observed along them [4,5]. Ridges have formed throughout Europa’s geologic history, creating identifiable crosscutting relationships [3,4]. These crosscutting relationships offer us an opportunity to determine the mechanisms responsible for ridge formation [6,...
