New social orders: reconceptualising family and community in utopian fiction

A study focusing on family and community as they are represented in seven utopian/dystopian fictions written for children and young adults by Australian, American, Canadian, and British writers is illustrated. These novels depict reflections of how various notions of new social orders have impacted on children's literature and how this affects the utopian/dystopian strain, present in children's literature.

Use of medical orders in acute care oxygen therapy

The life of every living organism is sustained by the presence of oxygen and the acute deprivation of oxygen will, therefore, result in hypoxia and ultimately death. Although oxygen is normally present in the air, higher concentrations are required to treat many disease processes. Oxygen is therefore considered to be a drug requiring a medical prescription and is subject to any law that covers its use and prescription. Administration is typically authorized by a physician following legal written instructions to a qualified nurse. This standard procedure helps prevent incidence of misuse or oxygen deprivation which could worsen the patients hypoxia and ultimate outcome. Delaying the administration of oxygen until a written medical prescription is obtained could also have the same effect. Clearly, defined protocols should exist to allow for the legal administration of oxygen by nurses without a physicians order because any delay in administering oxygen to patients can very well lead to their death.

New world orders in contemporary children's literature : utopian transformations

"New World Orders shows how texts for children and young people have responded to the cultural, economic, and political movements of the last 15 years. With a focus on international children's text produced between 1988 and 2006, the authors discuss how utopian and dystopian tropes are pressed into service to project possible futures to child readers. The book considers what these texts have to say about globalisation, neocolonialism, environmental issues, pressures on families and communities, and the idea of the posthuman."--BOOK JACKET.

New world orders and the dystopian turn : transforming visions of territoriality and belonging in recent Australian children's fiction

Through the 1990s and into the new millennium, Australian children's literature responded to a conservative turn epitomised by the Howard government and to new world order imperatives of democracy, the market economy, globalisation, and the IT revolution. These responses are evidenced in the ways that children's fiction speaks to the problematics of representation and cultural identity and to possible outcomes of devastating historical and recent catastrophes. Consequently, Australian children's fiction in recent years has been marked by a dystopian turn. Through an examination of a selection of Australian children's fiction published between 1995 and 2003, this paper interrogates the ways in which hope and warning are reworked in narratives that address notions of memory and forgetting, place and belonging. We argue that these tales serve cautionary purposes, opening the way for social critique, and that they incorporate utopian traces of a transformed vision for a future Australia. The focus texts for this discussion are: Secrets of Walden Rising (Allan Baillie, 1996), Red Heart (Victor Kelleher, 2001), Deucalian (Brian Caswell, 1995), and Boys of Blood and BOlle (David Metzenthen, 2003).

Risk assessment of sexual offenders for extended supervision orders in New Zealand : basic principles and current practice

A growing number of jurisdictions in North America, the United Kingdom, and Australasia have enacted legislation allowing for special sentencing, civil commitment, and community supervision options for high risk sexual offenders. In New Zealand, one example of this concern for public protection is the Parole (Extended Supervision) Amendment Act 2004, which provides for additional supervision of sexual offenders with child victims for up to 10 years after their release from prison. Recent experience with expert evidence and judicial decision making in such cases suggests that those involved in the process might benefit from a more thorough understanding of the current state of sexual offender risk assessment that can be provided by mental health professionals.

Assuming responsibility : teachers taking charge of their professional development

The paper reports on some of the findings of an extensive study undertaken in Victoria as part of a national Science, ICT and Mathematics Education in Rural and Regional Australia (SiMERR) project. One of the significant findings of the study was the extent to which teachers in the schools where the study data were collected took responsibility for many aspects of their own professional development. This was not at the expense of, but rather was in addition to, their involvement in school- and region-based professional development activity. The study also identifies some of the challenges faced, mostly related to the location of their schools in a rural or regional setting.

Measuring the summary informativeness of orders and trades

Improved preservation of order flow history from the automation of derivative trading platforms suggests that traders are potentially learning from the recent history of both order and trade parameters. Consequently, a model to measure price discovery should encapsulate the dynamic interaction between the price-size coordinates of orders and trades. The Hasbrouck (1991) model is extended to measure the summary informativeness of order size and trade size. The two models are used to test for price discovery improvements in the FTSE 100 index futures market from order flow consolidation post deletion of its E-mini counterpart. The informativeness of trades has declined sharply, while the informativeness of orders has risen significantly in the post deletion sample.

Plasticized single conductung polyelectrolytes based on poly (AMPS)

Poly(2-acrylamido-2-methyl-propane-1-sulphonic acid), poly(AMPS), has been ion exchanged with lithium and sodium to form alkali metal ion conducting polyelectrolytes. In the pure form these materials are rigid and would thus show limited conductivity. However addition of water or dimethylsulphoxide, as plasticizers, increases the conductivity by several orders or magnitude. The thermal analysis and NMR relaxation studies of these systems suggest that the increase in conductivity is as a direct result of increased ion mobility although the FTIR evidence still suggests significant ion association consistent with weak electrolytes. Although the Tg's of the sodium form of the polymer were higher, this system displayed higher conductivities than lithium which can be explained by a greater degree of ion dissociation and hence a larger number of charge carriers in the case of sodium poly(AMPS).

NMR determination of ionic structure in plasticized polyether-urethane polymer electrolytes

Solid polymer electrolytes based on amorphous polyether-urethane networks combined with lithium or sodium salts and a low molecular weight cosolvent (plasticizer) have been investigated in our laboratories for several years. Conductivity enhancements of up to two orders of magnitude can be obtained whilst still retaining solid elastomeric properties. In order to understand the effects of the plasticizers and their mechanism of conductivity enhancement, multinuclear NMR has been employed to investigate ionic structure in polymer electrolyte systems containing NaCF₃SO₃, LiCF₃SO₃ and LiClO₃ salts.

With increasing dimethyl formamide (DMF) and propylene carbonate (PC) concentration the increasing cation chemical shift with fixed salt concentration indicates a decreasing anion-cation association consistent with an increased number of charge carriers. ¹³C chemical shift data for the same systems suggests that whilst DMF also decreases cation-polymer interactions, PC does the opposite, presumably by shielding cation-anion interactions. Temperature dependent ⁷Li spin-lattice relaxation times indicate the expected increase in ionic mobility upon plasticization with a shift of the T₁ minimum to lower temperatures. The magnitude of T₁ at the minimum increases upon addition of DMF whereas there is a slight decrease when PC is added. This also supports the suggestion that the DMF preferentially solvates the cation whereas the action of PC is limited to coulomb screening, hence freeing the anion.

Towards a better understanding of 'delocalized charge' in ionic liquid anions

One of the main characteristics that are attributed to ionic liquids (especially those with a low melting point) is that the anions comprising the ionic liquids possess a certain degree of charge delocalization as compared to anions in traditional molten salts. Based on the proton affinity equilibrium we proposed a new energetic criterion that can be used as a measure of charge delocalization. The proposed proton affinity comparison quantifies the extent to which ionic liquid anions are delocalized. Thus it should lead to a better understanding towards the design of task-specific ionic liquids. Therefore, this criterion can be applied to newly designed anions to assure that the extent of charge delocalization falls within the same range of values on the proton affinity scale as other commonly used ionic liquid anions.

Nanoparticle enhanced conductivity in organic ionic plastic crystals : space charge versus strain induced defect mechanism

High conductivity in solid-state electrolytes is a critical requirement for many advanced energy and other electrochemical applications. Plastic crystalline materials have shown promise in this regard, and the inclusion of nanosized inorganic particles in both amorphous and crystalline materials has indicated order of magnitude enhancements in ion transport induced by space charge or other defect enhancement. In this paper we present conductivity enhancements in the plastic crystal N,N‘-ethylmethylpyrrolidinium bis(trifluoromethanesulfonyl)amide ([C₂mpyr][NTf₂]) induced by nanosized SiO₂ particles. The addition of the nanoparticles dramatically increases plasticity and ion mobility. Positron annihilation lifetime spectroscopy (PALS) measurements indicate an increase in mean defect size and defect concentration as a result of nanoparticle inclusion. The scaling of the conductivity with size suggests that a “trivial space charge” effect is operable, although a strain induced enhancement of defects (in particular extended defects) is also likely given the observed increase in plasticity.
