- A dyadic tile of order n is any rectangle obtained from the unit square by n successive bisections by horizontal or vertical cuts. Let each dyadic tile of order n be available with probability p, independent of the others. We prove that for p sufficiently close to 1, there exists a set of pairwise disjoint available tiles whose union is the unit square, with probability tending to 1 as n -> infinity, as conjectured by Joel Spencer in 1999. In particular, we prove that if p = 7/8, such a tiling exists with probability at least 1 - (3/4)(n). The proof involves a surprisingly delicate counting argument for sets of unavailable tiles that prevent tiling.

- We investigate the end users’ behaviours and attitudes with regards to the control they place in the personal information that they disclose to cloud storage services. Three controlled experiments were carried out to study the influence in users’ decisions to retain or surrender control over their personal information depending on different factors. The results of these experiments reveal, among other things, the users’ willingness to surrender control over personal information that is perceived as non-sensitive in exchange for valuable rewards, and that users would value the possibility of knowing and controlling the parties who are granted access to their data in the cloud. Based on the results from the experiments we provide implications for the design of end-user tools that can promote transparency and accountability in cloud computing environments.
