Word length distributions in modern Welsh prose texts.

This paper examines the distribution of word lengths in 12 prose texts written in modern Welsh (a P-Celtic language). The texts belong to the genres of new articles and Bible translation. For all texts, the observed frequencies can best be fitted by the 1-displaced Singh-Poisson distribution. This differs from published results on a Q-Celtic language (Scottish Gaelic) and suggests a P-celtic/Q-Celtic difference in word-length distribution. Further work is required to investigate other genres of Welsh as well as the other P- and Q-celtic languages

Words For Women's Boots in Present-Day Polish: A Quantitative and Contrastive Onomasiological Study

Footwear terminology demonstrates interesting cross-linguistic differences and is, consequently, also a problematic area for non-native speakers. In order to arrive at a more accurate picture of a subset of footwear terminology in present-day Polish, 82 native speakers were asked to name a range of six contemporary women's boot styles. No style showed a complete agreement in the preferred head noun, although a clear trend was evident for each one, with kozaki being the most commonly used overall. The possibly uniquely Polish use of a military metaphor for tall riding-style boots (oficerki) and the special subcultural case of Dr. Martens-style boots are discussed in particular. The choice of modifiers within noun phrases for boots is also examined. Some contrastive data are presented from speakers of Greek and Russian

Developing conceptual glossaries for the Latin vulgate bible.

A conceptual glossary is a textual reference work that combines the features of a thesaurus and an index verborum. In it, the word occurrences within a given text are classified, disambiguated, and indexed according to their membership of a set of conceptual (i.e. semantic) fields. Since 1994, we have been working towards building a set of conceptual glossaries for the Latin Vulgate Bible. So far, we have published a conceptual glossary to the Gospel according to John and are at present completing the analysis of the Gospel according to Mark and the minor epistles. This paper describes the background to our project and outlines the steps by which the glossaries are developed within a relational database framework

An extension of MacMahon's Equidistribution Theorem to ordered multiset partitions

A classical result of MacMahon states that inversion number and major index have the same distribution over permutations of a given multiset. In this work we prove a strengthening of this theorem originally conjectured by Haglund. Our result can be seen as an equidistribution theorem over the ordered partitions of a multiset into sets, which we call ordered multiset partitions. Our proof is bijective and involves a new generalization of Carlitz's insertion method. This generalization leads to a new extension of Macdonald polynomials for hook shapes. We use our main theorem to show that these polynomials are symmetric and we give their Schur expansion.Comment: An extended abstract of this work was presented at FPSAC 201

Circumnuclear starbursts in Seyfert galaxies

Observational diagnostics for the recognition of circumnuclear star formation in Seyfert galaxies are described and illustrated. These methods include: (1) spatially resolved optical spectroscopy, which allows the emission lines for HII regions to be separated from those originating in gas ionized by the Seyfert nucleus; (2) radio continuum mapping, where the linear radio sources characteristic of the nuclear activity may be distinguished from the diffuse morphology of multiple supernova remnants generated in a starburst; (3) infrared spectroscopic searches for emission features of dust, which are seen in starbursts but not in Seyfert nuclei; (4) the shape of the IRAS spectrum. These various diagnostics agree well as to the presence or absence of ongoing star formation. The IRAS spectra of a significant fraction of Seyferts are dominated by emission from dust heated by stars, not the Seyfert nucleus itself. In these cases, the spectrum is curved, being steep between 25 and 60 microns and flatter between 60 and 100 microns. When the Seyfert nucleus dominates, the 25 to 100 micron spectrum is much flatter. It is suggested that the location of a Seyfert galaxy in the IRAS color-color diagram reflects primarily the relative contributions of the active nucleus and dust heated by stars to the infrared fluxes

Copula Processes

We define a copula process which describes the dependencies between arbitrarily many random variables independently of their marginal distributions. As an example, we develop a stochastic volatility model, Gaussian Copula Process Volatility (GCPV), to predict the latent standard deviations of a sequence of random variables. To make predictions we use Bayesian inference, with the Laplace approximation, and with Markov chain Monte Carlo as an alternative. We find both methods comparable. We also find our model can outperform GARCH on simulated and financial data. And unlike GARCH, GCPV can easily handle missing data, incorporate covariates other than time, and model a rich class of covariance structures.Comment: 11 pages, 1 table, 1 figure.
