Jordan Cubes and Associative Powers

We study the relations between the powers of an associative algebra and the ideal generated by its Jordan cube. As a consequence, we describe the heart of an associative algebra for which every local algebra is simple in terms of associative powers, answering a question posed in [J. Algebra 240 (2001), 680-704]. We also provide examples which show that the results obtained are optimal.
