title: Investigating regional house price convergence in the United States: Evidence from a pair-wise approach

authors: Holmes, Mark J.

subjects: panel data

abstract: In this paper we examine long-run house price convergence across US states using a novel econometric approach advocated by Pesaran (2007) and Pesaran et al. (2009). Our empirical modelling strategy employs a probabilistic test statistic for convergence based on the percentage of unit root rejections among all state house price differentials. Using a sieve bootstrap procedure, we construct confidence intervals and find evidence in favour of convergence. We also conclude that speed of adjustment towards long-run equilibrium is inversely related to distance.

title: Information retrieval programs on the Internet: tools for teaching IR

authors: Cunningham, Sally Jo

subjects: computer science

abstract: The theory of information retrieval has generally been taught in theory: it has been difficult to provide students with hands-on experience with retrieval engines incorporating many IR topics such as relevance ranking, fuzzy queries, etc. Recently, however, a number of retrieval programs have become freely available for interactive use over the Internet. These programs can be useful in the classroom, by permitting students to examine a variety of implementations of IR algorithms over different document collections. Moreover, many of the document collections are in themselves valuable subject resources, and are well worth exploring from the point of view of development familiarity with them as reference materials.

title: /u/ fronting and /t/ aspiration in Māori and New Zealand English

authors: Maclagan, Margaret

subjects: Maori

abstract: This article examines the relationship between the frontness of /u/ and the aspiration of /t/ in both Māori and New Zealand English (NZE). In both languages, these processes can be observed since the earliest recordings dating from the latter part of the nineteenth century. We report analyses of these developments for three groups of male speakers of Māori spanning the twentieth century. We compare the Māori analyses with analyses of related features of the speakers' English and of the English of monolingual contemporaries. The occurrence of these processes in Māori cannot be seen simply as interference from NZE as the Māori-speaking population became increasingly bilingual. We conclude that it was the arrival of English with its contrast between aspirated and unaspirated plosives, rather than direct borrowing, that was the trigger for the fronting of the hitherto stable back Māori /u/ vowel together with increased aspiration of /t/ before both /i/ and /u/.
