Hyperbranched polymers—All problems solved after 15 years of research?

Solved and unsolved problems in generalized notions of Connes amenability

We survey the recent investigations on (bounded, sequential) approximate Connes amenability and pseudo-Connes amenability for dual Banach algebras. We will discuss the core problems concerning these notions and address the signicance of any solutions to them to the development of the eld.

What have we learnt after 15 years of research into the 'weekend effect'?

It is now 15 years since Bell and Redelmeier published their landmark study demonstrating higher mortality for people admitted to hospital during weekends compared with during the week. Examining the records of 3.8 million patients admitted over a 10-year period to emergency departments in Ontario, Canada, this ‘weekend effect’ existed over a range of acute conditions, including 23 out of the 1...

Collaboration Engineering: Reflections on 15 Years of Research & Practice

Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners without the ongoing support of external collaboration professionals. Research on CE started in the early 2000s with studies on ways to transfer professional collaboration expertise to novices using a pattern language called thinkLets. Subse...

Ten lessons from 15 years of transgenic Populus research

The goal of this paper is to describe the diverse kinds of research and interactions with the private and public sectors we have had while creating and field-testing many different kinds of transgenic poplars (genus Populus, aspens and cottonwoods) over the last ~15 years. [We use ‘transgenic’ to refer to any trees produced using asexual gene transfer, regardless of the origin of the genes.] Ou...
