Tales from the crypt ow many stem cells reside in a human colonic crypt and how do they divide and regenerate? According to the deterministic theory, a small number of " immortal " stem cells haunt a crypt, and when they divide, each generates a single replacement stem cell. The stochastic model, in contrast, contends that a crypt niche harbors many stem cells, and each cell division randomly g...

This study examines the incidence of sudden infant death syndrome (SIDS) in Canterbury (1973–1989) in relation to climate. Three mixture models (Finite Mixture, Zero-in)ated Poisson and Hurdle) are used as novel methods which are able to highlight di8erential e8ects of climatic covariates between months of SIDS and no SIDS. These methods accommodate the extra zeros, heterogeneity and autocorrel...

This paper investigates the stock returns and volatility size effects for firm performance in the Taiwan tourism industry, especially the impacts arising from the tourism policy reform that allowed mainland Chinese tourists to travel to Taiwan. Four conditional univariate GARCH models are used to estimate the volatility in the stock indexes for large and small firms in Taiwan. Daily data from 3...

We describe here our ongoing research on modeling conceptual and narrative structure of fairytales by a computer system. In this paper we focus on the variations of fairytales based on Cinderella from all around the world. We analyzed twenty-three Japanese texts of Cinderella tales and modeled their conceptual and narrative structures using the notions of composition elements and motifs. We the...

The Banks Peninsula tree weta, Hemideina ricta Hutton, is the rarest of the seven species of tree weta. Prior to our study it was known from only two locations on Banks Peninsula: Okains Bay (R. Bigelow, formerly Canterbury University, pers. comm.) and in totara (Podocarpus totara (G. Benn ex D. Don.)) logs near Purple Peak (P. Johns, Canterbury University, pers. comm.). The only other publishe...
