The ultimate goal of phonology is to uncover the mechanism whereby an indiscrete succession of sounds becomes a discrete chain of identifiable phonemes. A word falls naturally into morphemes and syllables. In the course of this double division two classes of languages emerge: those in which syllableand morpheme-boundaries always coincide and those in which this correspondence is not obligatory....

This is about a personal journey starting from my lifelong skepticism about statistical significance tests — perhaps the most mis-applied of all mathematical theories, especially as regards extreme events — toward a new clarity and power in the use of probability theory and a clear resolution of old dilemmas about subjectivity versus objectivity. There is little original thought here. Rather, t...

The residual dependence index of bivariate Gaussian distributions is determined by the correlation coefficient. This tail index is of certain statistical importance when extremes and related rare events of bivariate samples with asymptotic independent components are being modeled. In this paper we calculate the partial residual dependence indices of a multivariate elliptical random vector assum...

Roughly speaking, Large Deviations is a theory of rare events. It is probably the most active field in probability theory at present, one which has many surprising ramifications. One of its applications is to the analysis of the tails of probability distributions and, in recent years, this aspect of the theory has been widely used in queuing theory. The aim of this tutorial is to introduce the ...

In this paper, we extract and validate high-frequency oscillations in the port of Ploče, based on sea level data from one year (March 2002-March 2003) measured at a tide gauge in the harbor. Frequency was analyzed by applying stationary (spectral) and non-stationary (wavelet and filtering) analyses of the data to extract temporal characteristics of the fundamental seiches with a period of 30 mi...

Using the tail index of returns on US equities as a summary measure of extreme behaviour, we examine changes in the equity markets surrounding the development of program trading for portfolio insurance, the crash of 1987, and the subsequent introduction of circuit breakers and other changes in market architecture. Recentlydeveloped tests for the null of constancy of the tail index, versus the a...

Semantic expressiveness refers to how well a model reflects the underlying reality the model represents. Prior research has claimed the REA (Resources-Events-Agents) accounting model is more semantically expressive than is the traditional DCA (Debit-Credit-Account) accounting model. This research demonstrates experimentally that users perceive REA as more semantically expressive than DCA. This ...

Protected areas (PAs) are a cornerstone of conservation efforts and now cover nearly 13% of the world's land surface, with the world's governments committed to expand this to 17%. However, as biodiversity continues to decline, the effectiveness of PAs in reducing the extinction risk of species remains largely untested. We analyzed PA coverage and trends in species' extinction risk at globally s...

GM000887-PO-Waugh. f The intense cyclonic vortices that form over the winter pole are one of the most prominent features of the stratospheric circulation. The structure and dynamics of these “polar vortices” play a dominant role in the winter and spring stratospheric circulation and are key to determining distribution of trace gases, in particular ozone, and the couplings between the stratosphe...
