Evidence from a broad panel of countries shows little overall relation between income inequality and rates of growth and investment. However, for growth, higher inequality tends to retard growth in poor countries and encourage growth in richer places. The Kuznets curve—whereby inequality first

are both permeable and flexible. The complex interactions of time and uncertainty guarantee intellectual challenge and intrinsic excitement to the study of financial economics. Indeed, the mathematics of the subject contain some of the most interesting applications of probability and optimization theory

We are given a large database of customer transactions, where each transaction consists of customer-id, transaction time, and the items bought in the transaction. We introduce the problem of mining sequential patterns over such databases. We present three algorithms to solve this problem

Multiuser diversity is a form of diversity inherent in a wireless network, provided by independent time-varying channels across the different users. The diversity benefit is exploited by tracking the channel fluctuations of the users and scheduling transmissions to users when their instantaneous

comparisons. The mathematical model produces predictions about accuracy, mean reaction time, error latency, and reaction time distributions that are in good accord with experimental data. The theory is applied to four item recognition paradigms (Sternberg, prememorized list, study-test, and continuous

control, and exceptions. This paper defines the JFlow language and presents formal rules that are used to check JFlow programs for correctness. Because most checking is static, there is little code space, data space, or run-time overhead in the JFlow implementation.

. The WAM allows within its framework many variations e.g. regarding the term representation, the instruction set and the memory organization. Consequently several Prolog systems have implemented successful variants of the WAM. While these variants are eective within their own context, it is dicult to assess the merit of their particular variation. In this work, four term representations that were used by at least one successful system are compared empirically within dProlog, one basic implementation which keeps all other things equal. We also report on dierent implementation choices in the dProlog emulator itself. dProlog is reasonably ecient, so it makes sense to use it for these experiments. 1

simultaneously track multiple sources of sensitive data. TaintDroid’s efficiency to perform real-time analysis stems from its novel system design that leverages the mobile platform’s virtualized system architecture. TaintDroid incurs only 14 % performance overhead on a CPU-bound micro-benchmark with little

Many products have little or no value in isolation, but generate value when combined with others. Examples include: nuts and bolts, which together provide fastening services; home audio or video components and programming, which together provide entertainment services; automobiles, repair parts

Kernel based algorithms such as support vector machines have achieved considerable success in various problems in the batch setting where all of the training data is available in advance. Support vector machines combine the so-called kernel trick with the large margin idea. There has been little
