Mathematical Literacy: Myths, further inclusions and exclusions
Mathematical Literacy as a new subject in the final three years (grades 10 to 12) of schooling in South Africa is discussed. The discussion is driven by debates and deliberations around the introduction of Mathematical Literacy as they emerged in the public domain and constructs emanating from a diverse field of literature related to both mathematics and mathematical literacy. In particular the...
متن کاملExclusionary Discounts
We consider a two-period model with two sellers and one buyer in which the efficient outcome calls for the buyer to purchase one unit from each seller in each period. We show that when the buyer’s valuations between periods are linked by switching costs and at least one seller is financially constrained, there exist plausible conditions under which exclusion arises as the unique equilibrium out...
متن کاملSecretary problems: weights and discounts
The classical secretary problem studies the problem of selecting online an element (a “secretary”) with maximum value in a randomly ordered sequence. The difficulty lies in the fact that an element must be either selected or discarded upon its arrival, and this decision is irrevocable. Constant-competitive algorithms are known for the classical secretary problems (see, e.g., the survey of Freem...

متن کاملParameter Exclusions in H ´ Enon-like Systems
Φa(x, y) = (1− ax , 0) +R(a, x, y), ‖R(a, x, y)‖C3 ≤ b have a strange attractor, with positive Lebesgue probability in the parameter a, if the perturbation size b is small enough. We first sketch a geometric model of the strange attractor in this context, emphasising some of its key geometrical properties, and then focus on the construction and estimates required to show that this geometric mod...
