title: An econometric analysis of hotel–motel room nights in New Zealand with stochastic seasonality

authors: Lim, Christine

subjects: unit roots

abstract: Seasonality has attracted considerable interest in empirical tourism research and forecasting. However, the analysis of such recurring phenomenon is sparse in hospitality research, with very few studies to date having analysed seasonal unit roots prior to forecasting guest nights for the tourist-lodging industry. While pricing and other strategies have been implemented to extract greater revenue in the hospitality and tourism industry, it is also essential to focus the application of revenue or yield management based on seasonal demand analysis and forecasting. This paper examines the seasonality of hotel–motel room night occupancy patterns in New Zealand using monthly time series from 1997 to 2007. The presence of seasonal unit roots is detected using the Hylleberg, Engel, Granger and Yoo (HEGY) procedures. When the Box–Jenkins model of the HEGY-based transformed series is used to forecast hotel–motel room nights, its forecast performance is worse than that of the 12 differenced SARMA(2, 2)(0, 2) 12 model and the ARMA(2, 2) model for the original series.

title: An interactive graphic for visually fitting the generalized extreme value distribution

authors: Paramonov, Viacheslav

subjects: visual fitting

abstract: A utility developed for the Windows operating system enables easy visual curve fitting of the generalized extreme value distribution (GEV), from a screen display of annual maxima in a Gumbel plot. This gives a useful indication of how positioning of curves passing through the data points may result in similar or different return periods for large events. The utility employs a general risk-based time axis, with the usual return period being a special case option.

title: Te tuangi (the clam): A metaphor for teaching, learning and the key competencies

authors: Simpson, Mary Louisa

subjects: Early childhood

abstract: This article explores the shift from “essential skills” to “key competencies” in the school curriculum. Drawing on information gathered from teacher interviews and observations at a New Zealand primary school, this article suggests that culture and context strongly shape and influence the interpretation of key competencies. The authors develop a metaphor—te tuangi—to theorise the relationship between a learner (akonga) and a teacher (kaiako) in a cultural and social context.
