Previous studies have shown that many users do not use effective data deletion techniques upon sale or surrender of storage devices. A logical assumption is that many users are still confused concerning proper sanitization techniques of devices upon surrender. This paper strives to measure this assumption through a buyback study with a survey component. We recorded participants’ thoughts and be...

The fundamental aim in fisheries management is to determine an optimal fishing effort for sustainably harvesting from a replenishable resource. The current management objective of Australia’s Northern Prawn Fishery is to maximize the long-term net economic return following Australian government policy, resulting in an average recent catch of tiger prawn species of about 1,250 tons only. However...

F F Abstract—This paper analyzes the buyback contract of a supply chain including one retailer, one distributor and one supplier in a fuzzy decision making environment. The market demand is characterized as a fuzzy variable. To defuzzify the fuzzy number into a crisp one, the weighted possibilistic mean value method is applied, and the risk attitudes of the supply chain members are also conside...

In the matroid buyback problem, an algorithm observes a sequence of bids and must decide whether to accept each bid at the moment it arrives, subject to a matroid constraint on the set of accepted bids. Decisions to reject bids are irrevocable, whereas decisions to accept bids may be canceled at a cost which is a fixed fraction of the bid value. We present a new randomized algorithm for this pr...

There is general agreement that many, if not most, fisheries subsidies are detrimental to effective resource management. There is not, however, general agreement about subsidies used for decommissioning/buyback purposes. One school of thought argues that such subsidies can have a positive impact upon resource management, by removing excess fleet capacity from the fisheries. An opposing school o...
