Beyond access: informed participation and empowerment

This paper is based on the fundamental claim that one of the major roles of new media is not to deliver predigested information to individuals, but to provide the opportunity and resources for social debate and discussion. For most design problems (ranging from urban design to graphics design and software design) that we have studied over many years, the knowledge to understand, frame, and solv...

Access, Choice and Participation in Higher Education

Geographical distance between parental home and college poses a potential barrier to higher education (HE) entry, and could be a deciding factor when choosing between institutions. In particular, those on low incomes or with strong family commitments may be constrained in their education choices because they cannot afford to leave home, or have personal or cultural reasons to remain close to th...

Open access and global participation in science.

Previous investigations into the impact of open-access journals on subsequent citations confounded open and electronic access and failed to track availability over time. With new data, we separated these effects. We demonstrate that a journal receives a modest increase in citations when it comes online freely, but the jump is larger when it first comes online through commercial sources. This ef...

Interaction between Differentiating Cell- and Niche-Derived Signals in Hematopoietic Progenitor Maintenance

Maintenance of a hematopoietic progenitor population requires extensive interaction with cells within a microenvironment or niche. In the Drosophila hematopoietic organ, niche-derived Hedgehog signaling maintains the progenitor population. Here, we show that the hematopoietic progenitors also require a signal mediated by Adenosine deaminase growth factor A (Adgf-A) arising from differentiating ...
