Olympic analyses typically depend heavily on perspectives built from macro processes characteristically rooted in political economy. Using survey data of city residents gathered at six different points in time during the Vancouver 2010 Winter Olympics, this article proposes a focus on what happens within the host city during the Games. While the Olympics were the centre of much debate and controversy before the Games, the data show that attitudes towards the Games became much more favorable thereby providing hard evidence that the Olympics had an experiential urban impact. Regression models revealed that attending free unticketed events and supporting the Liberal party in the last provincial election were the best predictors of positive attitudes towards the Games. It is concluded that the Olympics represent a form of public policy which generates responses related to socio-political factors while also being an interactional event transforming local attitudes towards the Games.

The reference standard for identifying apneas and hypopneas is a pneumotachograph, but using this can disrupt sleep. Nasal airflow estimation by measuring nasal pressure via nasal prongs is better tolerated by patients. However, nasal pressure has not been validated, using an event-by-event analysis, for detecting apneas/hypopneas during sleep. Eleven patients undergoing polysomnography wore a nasal mask capable of measuring nasal airflow (via pneumotachograph) and nasal pressure simultaneously. Each study was screened for respiratory disturbances, and from these 550 were randomly selected and blindly scored as an apnea/hypopnea or no event each using the pneumotachograph, nasal pressure, square root nasal pressure, and respiratory inductance sum signals independently. Agreement was measured using Cohen's kappa statistic. Intermeasurement agreements between the pneumotachograph and nasal pressure, square root nasal pressure, and respiratory inductance plethysmography sum were 0.76, 0.73, and 0.50, respectively. Inter- and intrarater agreements were, respectively, 0.68 and 0.60 for the pneumotachograph, 0.66 and 0.82 for nasal pressure, 0.61 and 0.78 for square root nasal pressure, and 0.47 and 0.76 for respiratory inductance plethysmography sum. These results indicate that nasal pressure has excellent agreement compared with a pneumotachograph and very good inter-/intrarater agreement. Square root transformation of the nasal pressure signal does not improve these levels of agreement, indicating that it is unnecessary in routine clinical practice for scoring apneas/hypopneas.
