Weak covering properties and selection principles
No convenient internal characterization of spaces that are productively
Lindelof is known. Perhaps the best general result known is Alster's internal
characterization, under the Continuum Hypothesis, of productively Lindelof
spaces which have a basis of cardinality at most . It turns out that
topological spaces having Alster's property are also productively weakly
Lindelof. The weakly Lindelof spaces form a much larger class of spaces than
the Lindelof spaces. In many instances spaces having Alster's property satisfy
a seemingly stronger version of Alster's property and consequently are
productively X, where X is a covering property stronger than the Lindelof
property. This paper examines the question: When is it the case that a space
that is productively X is also productively Y, where X and Y are covering
properties related to the Lindelof property.Comment: 16 page

Some new directions in infinite-combinatorial topology
We give a light introduction to selection principles in topology, a young
subfield of infinite-combinatorial topology. Emphasis is put on the modern
approach to the problems it deals with. Recent results are described, and open
problems are stated. Some results which do not appear elsewhere are also
included, with proofs.Comment: Small update

Applying King et al.\u27s taxonomy to frame the IS discipline\u27s engagement in green IS discourse
This paper considers how the IS discipline can engage with discourse on the institutions and their interventions which influence and regulate green IS innovation. To consider possible responses, we apply King et al.’s (1994) taxonomy, based on Institutional Theory, to frame a research agenda to guide future exploration and debate on the interventions to facilitate green IS innovation. Through the application of the taxonomy, we derive several pertinent questions for the discipline to consider as part of this debate. We conclude that the IS discipline can, and indeed should, play a more prominent role both through traditional responses (e.g., descriptive studies of green IS methodologies, organisational best practice, maturity models, etc.), but also through more active engagement in the form of participation and advocacy in shaping future green policy and regulation.<br /
