Islands make up 5.3% of Earth’s land area yet maintain an estimated 19% of bird species, 17% of rodents, 17% of flowering plants, and 27% of human languages. Species diversity is disproportionately threatened on islands in relation to the islands’ proportion of both global land area and species, with 61% of all extinct species and 37% of all critically endangered species confined to islands…

Central to the concept of coupled human and natural systems (CHANS), humans and nature are organized into interacting subsystems of a cohesive whole at multiple spatial and temporal scales. Following an overview of the challenges in implementing the CHANS concept, we used widely available measures of social, economic, and ecological systems, including gross domestic product, population size, ne…

We consider almost-primes of the form f(p) where f is an irreducible polynomial over Z and p runs over primes. We improve a result of Richert for polynomials of degree at least 3. In particular, we show that, when the degree is large, there are infinitely many primes p for which f(p) has at most deg f + O(log deg f) prime factors.

A guest-worker program can be a very flexible and convenient way of meeting labor shortages in a host country, assuming that the migrants adhere to the rules of the program. This article investigates the conditions under which guest workers have sufficient incentives for voluntary return to their country of origin when their work permits expire. Should they choose to overstay, the article exa…

It proposes an alternative, affordance-based approach to lesson planning and makes a number of practical suggestions…
