Being Politically Impolite: Extending Politeness Theory to Adversarial Political Discourse

Abstract: This article attempts to extend politeness theory beyond informal situations to adversarial political discourse, using Prime Minister's Question Time in the British Parliament as data. Viewing the House of Commons as a `community of practice' (Lave and Wenger, 1991) provides a way of exploring concepts of politeness and impoliteness against a set of member expectations. The article argues three main propositions: (1) that much of the discourse of Prime Minister's Question Time is composed of intentional and explicitly face-threatening (or face-enhancing) acts and that these can be analysed in terms of both propositional and interactional levels: (2) that negative politeness features co-exist with the performance of intentional threats to the hearer's positive face and that these can only be understood and interpreted in relationship to Parliament as an institution and the wider political context; and (3) that systematic impoliteness is not only sanctioned but rewarded in accordance with the expectations o...

Wetting and wetting transitions on copper-based super-hydrophobic surfaces

Abstract: Rough and patterned copper surfaces were produced using etching and, separately, using electrodeposition. In both of these approaches the roughness can be varied in a controlled manner and, when hydrophobized, these surfaces show contact angles that increase with increasing roughness to above 160°. We show transitions from a Wenzel mode, whereby the liquid follows the contours of the copper surface, to a Cassie−Baxter mode, whereby the liquid bridges between features on the surface. Measured contact angles on etched samples could be modeled quantitatively to within a few degrees by the Wenzel and Cassie−Baxter equations. The contact angle hysteresis on these surfaces initially increased and then decreased as the contact angle increased. The maximum occurred at a surface area where the equilibrium contact angle would suggest that a substantial proportion of the surface area was bridged.

An international perspective on youth gambling prevalence studies

Abstract: In the wake of rapid expansion of legal gambling internationally, studies of adolescent gambling involvement and problem gambling prevalence have been carried out in numerous jurisdictions. This paper reviews adolescent gambling prevalence studies that have been carried out in North America, Europe, and Oceania. Based on this review, work is clearly needed to assess the impact of survey methods on identified prevalence rates and to improve the measurement of problem gambling among adolescents. From a substantive perspective, several clear demographic and behavioral characteristics are associated with gambling involvement and problem gambling among youth. However, early assumptions about youth gambling and problem gambling must give way to more nuanced understandings of how these phenomena change in response to changes in the social and cultural environment. We may have traveled some distance down the road toward understanding the determinants as well as the distribution of youth gambling and problem gambling, but we still have a long way to go.

Justify your alpha

Abstract: In response to recommendations to redefine statistical significance to P ≤ 0.005, we propose that researchers should transparently report and justify all choices they make when designing a study, including the alpha level.
