The return of manhood suffrage to Queensland, 1863-1872

In 1859, Queensland was separated from New South Wales as an independent colony. At this time the new Governor conspired to ensure the citizens did not inherit the old colonies system of full male suffrage. This was not returned until the Elections Act of 1872. However, the extended franchise was not a result of either democratic values or other ideological intentions. This article will analyse parliamentary debates to show that the revision to full suffrage was a result of administrative expediency driven by an inability to prevent abuse of the limited franchise.

The noblest of professions : schoolmasters at Hastings 1872-1894

The Noblest of Professions: Schoolmasters at Hastings 1872-1894 is a skilfully developed study of educational developments outside the Australian metropolises and in a small, but significant, pioneering rural community in the late colonial period. It is an important contribution to the formerly neglected field of local and regional history in Australia. It extends our knowledge of the life experiences of the schoolmaster in an isolated community and the regard local people had for him, together with the significant and varied social and leadership roles he played regularly and occasionally in rural affairs. The rural schoolmaster and his concerns are vividly brought to life in a compelling portrayal in this book. In all a very significant contribution to Australian history and to the history of education in its regional and local context.

Marcel Cousins : every little thing

This review considers the artwork of Melbourne artist Marcel Cousins showed at Ryan Renshaw Gallery, Brisbane in April 2012. The review traces Cousins' doctoral study in Tokyo. It then assesses his paintings and installations that explore the transformation of generic objects in exhibition contexts, as well as the aesthetic dimensions of such processes.

Cultural relativity as exchange : J.W. Lindt’s 'bush character and Aboriginal' from 'The Grafton Album', circa 1872

J.W.Lindt’s Colonial man and Aborigine image from the GRAFTON ALBUM: “On chemistry and optics all does not depend, art must with these in triple union blend” (text from J.W. Lindt’s photographic backing card) In this paper, I follow an argument that Lindt held a position in his particular colonial environment where he was simultaneously both an insider and an outsider and that such a position may be considered prerequisite in stimulating exchange. A study of the transition of J.W. Lindt in Grafton, N.S.W. in the 1860s from a traveller to a migrant and subsequently to a professional photographer, as well as Lindt’s photographic career, which evolved through strategic action and technical approaches to photography, bears witness to his cultural relativity. One untitled photograph from this period of work constructs a unique commentary of Australian colonial life that illustrates a non-hegemonic position, particularly as it was included in one of the first albums of photographs of Aborigines that Lindt gifted to an illustrious person (in this case the Mayor of Grafton). As in his other studio constructions, props and backdrops were arranged and sitters were positioned with care, but this photograph is the only one in the album that includes a non-Aborigine in a relationship to an Aborigine. An analysis of the props, technical details of the album and the image suggests a reconciliatory aspect that thwarts the predominant attitudes towards Aborigines in the area at that time.

Cryptanalysis of SIMON Variants with Connections

SIMON is a family of 10 lightweight block ciphers published by Beaulieu et al. from the United States National Security Agency (NSA). A cipher in this family with K -bit key and N -bit block is called SIMON N/K . We present several linear characteristics for reduced-round SIMON32/64 that can be used for a key-recovery attack and extend them further to attack other variants of SIMON. Moreover, we provide results of key recovery analysis using several impossible differential characteristics starting from 14 out of 32 rounds for SIMON32/64 to 22 out of 72 rounds for SIMON128/256. In some cases the presented observations do not directly yield an attack, but provide a basis for further analysis for the specific SIMON variant. Finally, we exploit a connection between linear and differential characteristics for SIMON to construct linear characteristics for different variants of reduced-round SIMON. Our attacks extend to all variants of SIMON covering more rounds compared to any known results using linear cryptanalysis. We present a key recovery attack against SIMON128/256 which covers 35 out of 72 rounds with data complexity 2123 . We have implemented our attacks for small scale variants of SIMON and our experiments confirm the theoretical bias presented in this work.

Improved linear cryptanalysis of reduced-round SIMON-32 and SIMON-48

In this paper we analyse two variants of SIMON family of light-weight block ciphers against variants of linear cryptanalysis and present the best linear cryptanalytic results on these variants of reduced-round SIMON to date. We propose a time-memory trade-off method that finds differential/linear trails for any permutation allowing low Hamming weight differential/linear trails. Our method combines low Hamming weight trails found by the correlation matrix representing the target permutation with heavy Hamming weight trails found using a Mixed Integer Programming model representing the target differential/linear trail. Our method enables us to find a 17-round linear approximation for SIMON-48 which is the best current linear approximation for SIMON-48. Using only the correlation matrix method, we are able to find a 14-round linear approximation for SIMON-32 which is also the current best linear approximation for SIMON-32. The presented linear approximations allow us to mount a 23-round key recovery attack on SIMON-32 and a 24-round Key recovery attack on SIMON-48/96 which are the current best results on SIMON-32 and SIMON-48. In addition we have an attack on 24 rounds of SIMON-32 with marginal complexity.
