Alien Son : The life and times of Cheok Hong Cheong, (Zhang Zhuoxiong) 1851-1928
This thesis contributes to the ongoing discussion of modern Chinese identity by providing a case study of Cheok Hong CHEONG. This thesis contributes to the ongoing discussion of modern Chinese identity by pro-viding a case study of Cheok Hong CHEONG. It necessarily considers Australian atti-tudes towards the Chinese during the 19th century, not least the White Australia Pol-icy. The emergence of that discriminatory immigration policy over the second half of the 19th century until its national implementation in 1901 provides the background to the thesis. Cheong was the leading figure among Chinese-Australian Christians and a prominent figure in the Australian Chinese community and the thesis seeks to iden-tify a man whose contribution has largely been shadowy in other studies or, more commonly, overlooked by the parochialism of colony/state emphasis in many histo-ries of Australia. His role in the Christian church fills a space in Victorian religious history. ¶ ..
Exceptionally large room-temperature ferroelectric polarization in the novel PbNiO3 multiferroic oxide
We present a study based on several advanced First-Principles methods, of the
recently synthesized PbNiO3 [J. Am. Chem. Soc 133, 16920 (2011)], a
rhombohedral antiferromagnetic insulator which crystallizes in the highly
distorted R3c crystal structure. We find this compound electrically polarized,
with a very large electric polarization of about 100 (\muC/cm)^2, thus even
exceeding the polarization of well-known BiFeO3. PbNiO3 is a proper
ferroelectric, with polarization driven by large Pb-O polar displacements along
the [111] direction. Contrarily to naive expectations, a definite ionic charge
of 4+ for Pb ion can not be assigned, and in fact the large Pb 6s-O 2p
hybridization drives the ferroelectric distortion through a lone-pair mechanism
similar to that of other Pb- and Bi-based multiferroic
Experimental investigations of #authenticity online
The concept of 'authenticity' is highly valued on social media sites (SMSes), despite its ambiguous nature and definition. One interpretation of 'authenticity' by media scholars is a human's congruence with online portrayals of themselves (e.g. posting spontaneous photographs from their lives, or using real biodata online). For marketers and 'influencers', these patterns of behaviour can achieve certain gains: sales for a business, or success of a campaign. For existentialist philosophers, using 'authenticity' as a means to an end is against its very definition. In this paper, I investigate what SMS users are looking for by their supposed 'authentic' portrayal online. My experimental approach draws upon empirical data from the Instagram social media site. Using machine learning techniques, descriptions and features of posts - including subjects, captions, and contexts - will be categorised and aggregated. I will then interpret these findings, drawing upon work by Taylor, Golomb, and Guignon, whose works on authenticity are based on mid-20th century existentalists. I argue that the existentialist ideals on authenticity are not necessarily present in contemporary SMS use. I will also argue that the popular interpretation of authenticity on SMSes can be self-defeating, when it seeks to turn the 'for-itself' into an 'in-itself'
Effects of pressure on spin fluctuations and the exchange interaction in La2CuO4 as determined by twoâmagnon Raman scattering (abstract)
We have measured the twoâmagnon Raman scattering spectrum of magnetic La2CuO4 at pressures of up to 100 kbar. Analysis of the moments of the twoâmagnon line shape indicates that the renormalization parameters resulting from spin fluctuations are essentially pressure independent in this pressure range. Our results provide the first direct determination of the pressure dependence of the inâplane exchange coupling constant J. The pressure dependence of J is compared with that of the NĂ©el temperature and discussed in the context of recent theories for quasiâtwoâdimensional magnetic systems.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/71024/2/JAPIAU-69-8-5392-1.pd
Ferroelectrically induced weak-ferromagnetism in a single-phase multiferroic by design
We present a strategy to design structures for which a polar lattice
distortion induces weak ferromagnetism. We identify a large class of
multiferroic oxides as potential realizations and use density-functional theory
to screen several promising candidates. By elucidating the interplay between
the polarization and the Dzyaloshinskii-Moriya vector, we show how the
direction of the magnetization can be switched between 180 symmetry
equivalent states with an applied electric field.Comment: Significantly revised for clarit
