Fast, Randomized Join-Order Selection - Why Use Transformations?

We study the effectiveness of probabilistic selection of join-query evaluation plans, t&hout reliance on tree transformation rules. Instead, each candidate plan is chosen uniformly at random from the space of valid evaluation orders. This leads to a transformation-free strategy where a sequence of random plans is generated and the plans are compared on their estimated costs. The success of this...

Why join groups? Lessons from parasite-manipulated Artemia.

Grouping behaviours (e.g. schooling, shoaling and swarming) are commonly explicated through adaptive hypotheses such as protection against predation, access to mates or improved foraging. However, the hypothesis that aggregation can result from manipulation by parasites to increase their transmission has never been demonstrated. We investigated this hypothesis using natural populations of two c...

Why Do Older Adults with Type 2 Diabetes Join a Diabetes Online Community?

Objective: As individuals age, chronic health difficulties may disrupt physical and social well-being. Individuals can turn to online communities to interact with similar peers, which may help buffer negative effects resulting from health difficulties. However, because the specific resources sought remain unclear, the present study investigated the reasons that older adults join a Diabetes Onli...
