normal today. The 1960 volume of the Financial Analysts Journal contains a pair of remarkable articles. In the first, “The Case for an Unmanaged Investment Company,” Edward Renshaw and Paul Feldstein compared the returns of mutual funds to those of the DJIA and found that only 11 of 89 diversified common stock and balanced funds had returns higher than those of the DJIA. This and similar eviden...

We outline the design and operation of Pasta, a peer-topeer storage system that provides traditional file system semantics while offering the wide-spread caching and distribution required for publishing networks. Pasta allows users to manipulate shared files and folders with strong consistency semantics and to collaboratively organize them in unmanaged decentralized namespaces. Storage quotas r...

The purpose of these papers is to identify ways in which scavenging village poultry production can be improved at little or no cost. There has recently been much recognition given to this system, particularly amongst the very poor, because of its major role in food security, nutrition and income. Scavenging chickens are normally unmanaged with few or no inputs. Here, focus is on improving bird ...

Denitrification and hydrologic leaching are the two major pathways by which nitrogen is lost from the terrestrial biosphere. Humid tropical forests are thought to dominate denitrification from unmanaged lands globally, but there is large uncertainty about the range and key drivers of total N gas emissions across the biome. We combined pantropical measures of small watershed stream chemistry wit...

In this paper, we investigated the forms of visibility and intrusion present during learning and offer initial findings based on our observations at two secondary schools. We have identified that visibility and intrusion exists in various forms of interactions in learning and could have negative consequences in learning if they are left unmanaged. We propose the usage of interactive surface as ...

We examine how control over a technology platform can increase profits and innovation. By choosing how much to open and when to bundle enhancements, platform sponsors can influence choices of ecosystem partners. Platform openness invites developer participation but sacrifices direct sales. Bundling enhancements early drives developers away but bundling late delays platform growth. Ironically, d...

Transient use of PCs has grown in importance with the advent of Internet cafes and the emergence of personalization systems such as Migo, GoToMyPC, and Internet Suspend/Resume. r © Unfortunately, users have no choice today but to trust any transient hardware they use. They are often unaware of the risks they face in placing faith in public computers. We address this problem through Trust-Sniffe...

As computers inevitably begin to replace humans as the drivers of automobiles, our current human-centric traffic management mechanisms will give way to hyper-efficient systems and protocols specifically designed to exploit the capabilities of fully autonomous vehicles. We have introduced such a system for coordinating large numbers of autonomous vehicles at intersections [4, 5]. Our experiments...
