Abstract Seaweed farmers have not benefited much from seaweed marketing activities, especially in dry form. Marketing of Bantaeng Regency general has been maximized, the community able to properly market their crops. The cultivating is tied traders, where when takes cultivation needs are obliged submit harvest that’s trader’s profit plays on price seaweed, collectors take at prices, so that rec...

The financing of higher education throughout the world has seen dramatic changes in the last decades of the 20 and the first decade of the 21 centuries. In the main, these changes in financing are responses to a worldwide phenomenon of higher educational costs tending to rise at rates considerably in excess of the corresponding rates of increase of available revenues, especially those revenues ...

This paper finds and analyzes a formula for the total variation distance between iterations of riffle shuffles and iterations of “cut and then riffle shuffle”. This allows one to obtain information about the convergence rate of permutation statistics (such as the length of the longest increasing subsequence or position of a given card) under these processes. Similar results are given for affine...

Abstract. We compute the limit distribution for (centered and scaled) length of the longest increasing subsequence of random colored permutations. The limit distribution function is a power of that for usual random permutations computed recently by Baik, Deift, and Johansson (math.CO/9810105). In two–colored case our method provides a different proof of a similar result by Tracy and Widom about...

We prove a formula for the number of permutations in Sn such that their first n−k entries are increasing and their longest increasing subsequence has length n − k. This formula first appeared as a consequence of character polynomial calculations in the work of Adriano Garsia, [2]. We give an elementary proof of this result and also of its q-analogue. In [2], Adriano Garsia derived as a conseque...

This note discusses the relationships among three assumptions that appear frequently in the pricing/revenue management literature. These assumptions are mostly needed for analytical tractability, and they have the common property of ensuring a well-behaved “revenue function.” The three assumptions are decreasing marginal revenue with respect to demand, decreasing marginal revenue with respect t...

This paper studies revenue-sharing contracts in distribution chains in the presence of win-win conditions. Revenue-sharing contracts are a mechanism to coordinate the firms in a distribution chain. Under these contracts the retailer shares its revenue with the supplier in exchange for a lower wholesale price. The win-win conditions are natural conditions requiring that the profit of any firm ma...
