We examine the holography bound suggested by Bousso in his covariant entropy conjecture, and argue that it is violated because his notion of light sheet is too generous. We suggest its replacement by a weaker bound.

South Africa is an important country within the continent of Africa. Its full adoption of International Financial Reporting Standards (IFRS) in 2005 for listed firms is unique. In this paper, I study the effects of IFRS adoption on accounting quality. I define accounting quality as earnings quality and value relevance, and hypothesize that both will increase post IFRS adoption. In a variety of ...

Recently, all the human genes were identified. But understanding the functions coded in the genes is a much harder problem. We are used to view DNA as some sort of a computer code, but there are striking differences. For example, by using entropy, it has been shown that the DNA code is much closer to random code than written text, which in turn is less ordered than ordinary computer code. Inste...

and the participants of the Stanford GSB Joint Accounting/Finance student seminar for their helpful comments and suggestions. All remaining errors are my own.

When a dataset involves multiple classes, there is often a need to express the key contrasting features among these classes in humanly understandable terms, that is, to pro"le the classes. Commonly, one class is contrasted from the rest by aggregating the latter into a pseudo-class; alternatively, classes are treated separately without coordinating their pro"les with those of the other classes....

A distinct feature of an adaptive e-learning hypermedia system (AEHS) is the learner model it employs, that is, a representation of information about an individual learner. Learner modeling and adaptation are strongly correlated, in the sense that the amount and nature of the information represented in the learner model depend largely on the kind of adaptation effect that the system has to deli...

This article outlines a hybrid method, incorporating multiple techniques into an evaluation process, in order to select competitive suppliers in a supply chain. It enables a purchaser to do single sourcing and multiple sourcing by calculating a combined supplier score (CSS), which accounts for both qualitative and quantitative factors that impact on supply chain performance. By performing a clu...

A distinguishing feature of the period preceding the 2007/08 financial crisis was the sizeable increase in private sector debt observed across many countries. A key component of household liabilities is mortgage debt and with many countries experiencing persistent increases in house prices from the mid-1990s onwards, a marked increase in this aspect of household leverage was observed. While agg...
