Traces and shards of self-injury: Strange accounting with “Author X”
No full textIn this strange account autoethnography, three or four authors explore their lived experiences with self-injury. Strange accounting is both a post-modern style of text, and a method for keeping identities concealed when risks and secrets are in play. Author X, a post-modern place-keeper for an anonymous author who may or may not have contributed to this manuscript, introduces a new dimension and layer of concealment. With Author X in-play and under erasure, the reader will never be sure if there were three or four authors on this manuscript. Through strange accounting, a post-structuralist/postmodernist frame will be applied to understanding the self-injury experience. We frame self-injury as a social practice and, for some, an everyday norm, while remaining acutely aware of the stigma surrounding the topic of self-injury. Each of us, coupled with Author X, provide the others cover to trace stories of self-injury through the literature, our flesh, and our lives
Editorial: Professors as leaders
No full textOne of us (RW) was asked recently to address the role of professors as leaders in the 21st century at an international nursing education conference in
Hong Kong and this has stimulated us to think further on this issue. We have addressed the issue of the professoriate in nursing before (Watson & Thompson
2004, Thompson & Watson 2006) and this has drawn criticism and stimulated debate (Rolfe 2007). However, we have largely bemoaned the state of the nursing professoriate, especially in the UK, in terms of the ease with
which the title is sometimes obtained and the activities that are purportedly promoted within the role. © 2008 Blackwell Publishing Lt
Continuous images of products of separable spaces
No full textAbstractThe aim of this note is to show, using elementary submodels, the following result: “Let X be a space of countable tightness which is the continuous image of a product of separable spaces. Then X is separable”. As a corollary we obtain that if a space of countable tightness is the continuous closed image of a product of separable metrizable spaces then it is the continuous closed image of a separable metrizable space. For notation and terminology we refer the reader to the work of Engelking (1989) and Hodel (1984). Our approach to elementary submodels follows that of Watson (1994)

A simple two-module problem to exemplify building-block assembly under crossover
No full textTheoretically and empirically it is clear that a genetic algorithm with crossover will outperform a genetic algorithm without crossover in some fitness landscapes, and vice versa in other landscapes. Despite an extensive literature on the subject, and recent proofs of a principled distinction in the abilities of crossover and non-crossover algorithms for a particular theoretical landscape, building general intuitions about when and why crossover performs well when it does is a different matter. In particular, the proposal that crossover might enable the assembly of good building-blocks has been difficult to verify despite many attempts at idealized building-block landscapes. Here we show the first example of a two-module problem that shows a principled advantage for cross-over. This allows us to understand building-block assembly under crossover quite straightforwardly and build intuition about more general landscape classes favoring crossover or disfavoring it
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Combining international student social and academic transition online
No full textThe social and academic acculturation of a large number of newly arrived international students challenges even the most prepared of UK higher education institutions. How best to facilitate students’ social need to form new friendships with that of formally preparing them for the often unfamiliar academic demands of a different educational system? This paper will present a pre-arrival online course delivered to over 2,000 international students each summer, which combines student-centred socialisation with institution-driven academic preparation. From the initial data, it will draw some tentative conclusions about how far this approach could help facilitate students’ transition in advance of their arrival
