On the Closing Lemma problem for vector fields of bounded type on the torus

We investigate the open Closing Lemma problem for vector fields on the 2-dimensional torus. Under the assumption of bounded type rotation number, the $C^r$ Closing Lemma is verified for smooth vector fields that are area-preserving at all saddle points. Namely, given such a $C^r$ vector field $X$, $r\geq 4$, with a non-trivially recurrent point $p$, there exists a vector field $Y$ arbitrarily near to $X$ in the $C^r$ topology and obtained from $X$ by a twist perturbation, such that $p$ is a periodic point of $Y$. The proof relies on a new result in 1-dimensional dynamics on the non-existence of semi-wandering intervals of smooth maps of the circle.Comment: 11 pages, 1 figur

Discursive mobile phone practices and informal rules

This paper uses Discourse Analysis (DA) to investigate the socially\ud constructed discursive practices of mobile phone use; specifically it examines the\ud informal rules of mobile phone use. It qualitatively investigates mobile phone use\ud within an Australian cultural context. „Discourse theory begins with the\ud assumption that all objects and actions are meaningful, and that their meaning is a\ud product of historically specific systems of rules‟ (Howarth 2000, p. 8). Evidence\ud of socially constructed textual meanings related to mobile phone use is found in\ud the informal rules created (and practiced); those that in some way govern the use\ud of mobile phones. The research reveals that there are divergences and\ud inconsistencies within the discourse of mobile phone use, and illustrates that\ud individuals make differing personal choices in similar social contexts
