Beyond Cheap Oil
As I read authoritative reports by well-known petroleum geologists on the Internet about the end of Cheap Oil, I became more and more engrossed about this greatest story never told. (In fact, the story has been told, but it has never reached the press headlines.) I wanted to know how it all turns out. It is surprising how much high quality, authoritative information can be obtained from a caref...
متن کاملDebunking the 'digital native': beyond digital apartheid, towards digital democracy
This paper interrogates the currently pervasive discourse of the 'net generation' finding the concept of the 'digital native' especially problematic, both empirically and conceptually. We draw on a research project of South African higher education students' access to and use of Information and Communication Technologies (ICTs) to show that age is not a determining factor in students' digital l...
متن کاملBeyond the RPA on the cheap: improved correlation energies with the efficient “Radial Exchange Hole” kernel
The “ACFD-RPA” correlation energy functional has been widely applied to a variety of systems to successfully predict energy differences, and less successfully predict absolute correlation energies. Here we present a parameter-free exchange-correlation kernel that systematically improves absolute correlation energies, while maintaining most of the good numerical properties that make the ACFD-RPA...
متن کاملLight Fields on the Cheap
This paper presents a new light field capture system where the main design goal is low cost. To minimize cost we use an off-the-shelf flatbed scanner as the digitizing element. However, intrinsic properties of scanners can adversely affect resultant images. We will survey these properties and their effects in raw outputs. Image manipulation techniques will then be discussed so that proper light...
متن کاملKnowledge: Value on the Cheap
We argue that the so-called ‘Primary’ and ‘Secondary’ Value Problems for knowledge are more easily solved than is widely appreciated. Pritchard, for instance, has suggested that only virtue-theoretic accounts have any hopes of adequately addressing these problems. By contrast, we argue that accounts of knowledge that are sensitive to the Gettier problem are able to overcome these challenges. To...
