Radio Observations of Two Isolated Neutron Stars, RXJ0720.4-3125 and RX J0806.4-4132

Radio observations of two isolated neutron stars, RXJ0720.4-3125 and RX J0806.4-4132, have been made with the Australia Telescope Compact Array at a frequency of 1.4 GHz. No continuum emission is detected from either object with a 3 sigma upper limit of 0.2 mJy. The data were also folded synchronously with the known rotation periods of 8.4 and 11.4 s respectively. No pulsed emission was detected. If the pulse duty cycle is small, the upper limit on pulsed emission can be reduced still further to 0.04 mJy. The best evidence seems to indicate that the isolated neutron stars detected by ROSAT all-sky survey are relatively young objects, born with a very high magnetic field.Comment: Accepted for publication in MNRAS. 4 pages, 4 figure

The Unity of a Tractarian Fact

It is not immediately clear from Wittgenstein’s Tractatus how to connect his idea there of an object with the logical ontologies of Frege and Russell. Toward clarification on this matter, this paper compares Russell’s and Wittgenstein’s versions of the thesis of an atomic fact that it is a complex composition. The claim arrived at is that whilst Russell (at times at least) has one particular of the elements of a fact – the relation – responsible for the unity of the whole, for Wittgenstein the unity of a fact is the product of copulative powers inherent in all its elements. All kinds of constituents of Tractarian facts – all kinds (forms) of object – are, to use Fregean terminology, unsaturated.Articl

Conjugacy classes of parabolic subalgebras in complex semi-simple lie algebras

For a complex semi simple Lie algebra g, Richardson's dense orbit theorem gives a map between conjugacy classes of parabolic subalgebras in g and conjugacy classes of nilpotent elements. Unfortunately, this map is not surjective, in general, and hence does not give a direct classification of the nilpotent conjugacy classes in g. Despite this, the theorem is used by Bala and Carter to produce an indirect classification of the nilpotent conjugacy classes in g. The map is not injective, either, and this thesis attempts to discover a necessary and sufficient condition for two parabolic subalgebras to give the same nilpotent conjugacy class under the above map. Springer conjectured that associated parabolics would give the same nilpotent conjugacy class. The problem was also raised in another form by Dixmier in his work concerning the distribution of nilpotent polarisable elements in g. He conjectured a generalisation of Kostant's results on the regular nilpotent elements. We prove both these conjectures correct, the method of proof being inspired by Dixmier's work. Unfortunately, the necessary and sufficient condition is clearly more complicated than this and we give two examples (one trivial, one non-trivial) of non-associated parabolics giving the same nilpotent conjugacy class under Richard son's ma

Imprisoned mothers in Victorian England, 1853–1900: Motherhood, identity and the convict prison

This article explores the experiences of imprisoned mothers in the Victorian convict prison system. It argues that motherhood, of central importance to the ideals of Victorian femininity, was disrupted and fractured by women's long-term imprisonment. Using 'whole life' history methodology, the paper draws on research into 288 women imprisoned and then released from the prison system, of whom half were mothers. It illuminates how the long term prison system dealt with pregnancy, childbirth and family contact for female prisoners. It argues that whilst institutional or state care was often an inevitable consequence for children of single or widowed mothers, women used their limited resources and agency to assert their identity as mothers and direct outcomes for their children. But for others, prolific offending and multiple long sentences would render any chance of motherhood impossible

The Topp Twins: Untouchable girls: The movie

The recently released documentary The Topp Twins: Untouchable Girls: The Movie (2009) has quickly become an important cultural text in Aotearoa New Zealand. It opened on April 9, 2009 and immediately broke records for best opening day and weekend in New Zealand’s movie history. For readers to get some sense of this documentary, it is worth watching the trailer (http://topptwins.com/tv-and-film/untouchable-girls) which provides a tantalising peak into the life story, so far, of the Topp Twins – much loved New Zealand entertainers. But the documentary does more than chart life stories, it highlights major social and political movements that helped shape national discourses of what it feels like to be a ‘Kiwi’ (the term ‘Kiwi’ is used by people – of all ethnicities and social classes - who feel they have a New Zealand national identity). I have chosen this documentary for this scholar’s choice essay because it links with a number of discourses that inspire my work on how emotions such as ‘pride’ shape people and place. Untouchable Girls illustrates the fluidity and partiality of subjectivities (both individually and collectively) and the ways in which subjectivities can be challenged and contested without humiliation
