We present an algorithm that minimizes the expected cost of indirect binary search for data with non-constant access costs (e.g. disk data). The term \indirect" indicates that sorted access to the data is obtained through an array of pointers to the raw data. One immediate application of this algorithm is to improve the retrieval performance of disk databases that are indexed using the suux arr...

A large database, such as POS data, could give us many insights about customer behavior. Many techniques and measures have been proposed to extract the interesting rules. As the study of Association rule mining has proceeded, the rules about items that are not bought together at the same transaction have been regarded as important. Although this concept, Negative Association rule mining, is qui...

How much can a constituency influence the power of its representative in the legislature? We develop a theoretical model of the constituency basis of legislator influence. The key players in the model are interest groups who may receive targeted transfers from the legislature. The model predicts that the amount of transfers that such groups receive is increasing in their ability to help a party...

It is a well-known fact that financial returns exhibit conditional heteroscedasticity and fat tails. While the GARCH-type models are very popular in depicting the conditional heteroscedasticity, the α-stable distribution is a natural candidate for the conditional distribution of financial returns. The α-stable distribution is a generalization of the normal distribution and is described by four ...

Leaf damage induces in many plant species the secretion of extrafloral nectar (EFN) and/or the release of specific odours (volatile organic compounds, VOCs). Both traits attract carnivorous arthropods and function as indirect plant defences by increasing the predation pressure on attacking herbivores. We have conducted field experiments in Mexico and found that plants that had been exposed to V...

This dissertation describes a general code-improving transformation that can coalesce conditional branches into an indirect jump from a table. Applying this transformation allows an optimizer to exploit indirect jumps for many other coalescing opportunities besides the translation of multiway branch statements. First, data ow analysis is performed to detect a set of coalescent conditional branc...

The purpose of negotiation is to enable agents to coordinate their actions. Characterizing coordination in informationtheoretic terms leads us to consider negotiation in the context of other processes that can transfer information among agents, such as those mediated by the environment. We illustrate these concepts using the Minority Game, an abstract model of resource allocation that achieves ...

This paper contributes to two debates: (i) the debate about whether or not ancient Greek has Free Indirect Discourse (FID), and (ii) the debate about how we should analyze FID semantically. We do this by showing that there is a distinction between FID and what we call Unembedded Indirect Discourse (UID). The semantic analysis that we develop for the latter shows that the two phenomena, though s...

Indirect traumatic optic neuropathy (ITON) refers to optic nerve injury resulting from impact remote to the optic nerve. The mechanism of injury is not understood, and there are no confirmed protocols for prevention, mitigation or treatment. Most data concerning this condition comes from case series of civilian patients suffering blunt injury, such as from sports- or motor vehicle-related concu...
