The Australian Government`s abandoned infrastructure outsourcing program: "fiasco" or relatively typical?

Early in 2001, after a damning public report by the Auditor-General, the Australian Federal Government was forced to abandon its highly promoted “whole of government” infrastructure outsourcing initiative. This about-face was greeted in the press with reports that the initiative was a “fiasco”. Yet a four-year case study of the initiative suggests a more complex picture. The initiative can be viewed in a quite different light on the basis of comparisons with a contemporary survey of 240 Australian organisations engaged in IT outsourcing. This reveals that many of the negative outcomes associated with this “fiasco” are typical of those experienced by large Australian organisations. This has important implications for decision makers confronted with choices about sourcing IT service delivery.

Pretend play and maternal scaffolding : comparisons of toddlers with advanced development, typical development, and hearing impairment

This study used measures of pretend play and maternal scaffolding to explore and compare the early development of deaf children, typically developing children, and children showing advanced intellectual development. Marked differences were found among the groups in both play development and characteristics of mother-child interactions. In particular, children who scored above 130 IQ at four years of age were found, as toddlers, to have demonstrated significantly advanced pretend play. In addition, the mothers of the high IQ children engaged in scaffolding behaviors involving higher stages of pretend transformations, verbal analogies and world links. The findings are discussed in relation to children's learning in Vygotsky's Zone of Proximal Development, as well as possible implications for future research on early gifted development.

A typical meteorological year for energy simulations in Hamilton, New Zealand

Typical Meteorological Year (TMY) data is used extensively in building energy simulations and solar energy analysis. TMY data for New Zealand, however, is relatively limited and no such data existed for Hamilton. Ten years of hourly meteorological data was analysed, and a TMY was developed. Simulations using the TMY data were conducted to determine the performance of a solar pool-heating system. It was found that the TMY was able to predict the annual performance of this system to within 2% of the long-term mean. It is intended that this TMY could be used to perform simulations on building energy use and solar heating systems in Hamilton.

Novel Lewis-base ionic liquids replacing typical anions

We have synthesized two kinds of new Lewis-base ionic liquids (ILs); one is based on the relatively strong Lewis basic acetate anion, and the other is a salt composed of a mono-alkylated diamine such that the Lewis base site is incorporated in the cation. 1-Octyl-4-aza-1-azonia-bicyclo[2.2.2]octane bis(trifluoromethanesulfonyl)amide, [C₈dabco]TFSA, and N-butyl-N-methylpyrrolidinium acetate, [p_1,4]OAc, melted into fluid liquids at 26 and 81 °C, respectively. The thermal decomposition of [p_1,4]OAc started at around 150 °C, whereas the thermal stability of [C₈dabco]TFSA was almost equal to that of typical TFSA-based ILs in spite of the Lewis base site. This suggests that if the Lewis base site is incorporated into the cation the IL can maintain higher thermal stability. In addition, as a further result of the presence of the basic nitrogen, [C₈dabco]TFSA can dissolve hydrated Cu(NO₃)₂ whereas the other TFSA-based ILs cannot.

Atypical mood stabilizers : a 'typical' role for atypical antipsychotics

Objective: To assess the potential role of atypical antipsychotics as mood stabilizers.

Method: A MedLine, PsychLIT, PubMed, and EMBASE literature search of papers published up to December 2004 was conducted using the names of atypical antipsychotics and a number of key terms relevant to bipolar disorder. Additional articles were retrieved by scrutinizing the bibliographies of review papers and literature known to the authors. Data pertinent to the objective was reviewed according to the various phases of bipolar disorder.

Results: The data is most substantive for the use of atypical antipsychotics in mania, to the extent that an argument for a class effect of significant efficacy can be made. This does not extend to bipolar depression, however, good data is now emerging for some agents and will need to be considered for each individual agent as it accumulates. As regards mixed states and rapid cycling the evidence is thus far sparse and too few maintenance studies have been conducted to make any firm assertions. However, with respect to long-term therapy the atypical antipsychotics do have clinically significant side-effects of which clinicians need to be aware.

Conclusion: Based on the evidence thus far it is perhaps premature to describe the atypical antipsychotics as mood stabilizers. Individual agents may eventually be able to claim this label, however, much further research is needed especially with respect to maintenance and relapse prevention.

Understanding of mental states in later childhood: an investigation of theory of mind in autism spectrum disorder and typical development with a novel task

The developmental trajectories of Theory of Mind (ToM) in later childhood and into adolescence have not been thoroughly investigated, partly due to a lack of sensitive paradigms that can chart development in typical populations or in individuals with a core deficit in ToM, such as those with autism spectrum disorder (ASD). The present study assessed understanding of emotions, beliefs, and intentions using both an established ToM task (Baron‐Cohen et al., 2001) and the more recently developed Comic Strip Task (CST; Cornish et al., 2010). Participants comprised 12 typically-developing (TD) children (mean age: 12·0 years, range: 9·9‐14·8 years) and 12 high-functioning children with ASD (mean age: 11·0 years, range: 9·1‐13·6 years). Results indicated that the ASD group were not impaired on any of the ToM tasks relative to TD children. It was concluded that although children with high-functioning ASD appear to develop basic ToM skills, they do not generalize these to naturalistic situations. The comic-strip paradigm is suggested as a promising way to approach the measurement of ToM across childhood in typical children and those with ASD.

Typical and atypical haemolytic uraemic syndrome: A brief case comparison report for nurses

Background: Haemolytic uraemic syndrome (HUS) is one of the main causes of acute kidney injury in children. It is a multifaceted disease, characterised by microangiopathic haemolytic anaemia and thrombocytopaenia. It can often affect multiple organ systems, including the central nervous and renal systems.

Impact analysis study in a typical solar PV microgrid power system

Microgrid (MG) power system with Distributed Generation (DG) plays an important role to provide reliable, secure, and low carbon emission energy supply for communities, in case of any failure or disturbance of energy supply from the main grid. At the same time, DG also contributes to several technical issues in the MG distribution network. Power quality (PQ) issues are one of the main technical challenges when integrating Renewable Energy (RE) sources in MG network. In this paper, the PQ issues like; power variation, voltage deviation, and Total Harmonic Distortion (THD) have been addressed by an impact analysis study on a typical solar PV MG power system in both on-grid and off-grid mode of operation. Analysis results from the study will be helpful in developing an independent MG power system with improved PQ conditions.

Modelling the maturation of grip selection planning and action representation: insights from typical and atypical motor development

We investigated the purported association between developmental changes in grip selection planning and improvements in an individual’s capacity to represent action at an internal level (i.e., motor imagery). Participants were groups of healthy children aged 6-7 years and 8-12 years respectively, while a group of adolescents (13-17 years) and adults (18-34 years) allowed for consideration of childhood development in the broader context of motor maturation. A group of children aged 8-12 years with probable DCD (pDCD) was included as a reference group for atypical motor development. Participants’ proficiency to generate and/or engage internal action representations was inferred from performance on the hand rotation task, a well-validated measure of motor imagery. A grip selection task designed to elicit the end-state comfort (ESC) effect provided a window into the integrity of grip selection planning. Consistent with earlier accounts, the efficiency of grip selection planning followed a non-linear developmental progression in neurotypical individuals. As expected, analysis confirmed that these developmental improvements were predicted by an increased capacity to generate and/or engage internal action representations. The profile of this association remained stable throughout the (typical) developmental spectrum. These findings are consistent with computational accounts of action planning that argue that internal action representations are associated with the expression and development of grip selection planning across typical development. However, no such association was found for our sample of children with pDCD, suggesting that individuals with atypical motor skill may adopt an alternative, sub-optimal strategy to plan their grip selection compared to their same-age control peers.

Power quality impacts in a typical microgrid

Microgrid (MG) power system plays an important role to fulfill reliable and secure energy supply to critical loads of communities as well as for communities in remote area. Distributed Generation (DG) sources integrated in a MG provides numerous benefits, at the same time leads to power quality issues in the MG power distribution network. Power Quality (PQ) issue arises due to the integration of an intermittent nature of Renewable Energy (RE) sources with advanced Power Electronics (PE) converter technology. Also, presence of non-linear and unbalancing loads in MG seems to affect PQ of the energy supply in power distribution network. In this paper, PQ impacts like; power variation, voltage variation, Total Harmonic Distortion (THD), and Unbalance voltage level have been analysed in Low Voltage (LV) distribution network of typical MG power system model. In this study, development of MG model and PQ impact analysis through simulation has been done in PSS-Sincal software environment. Analysis results from the study can be used as a guideline for developing a real and independent MG power system with improved PQ conditions.

Impacts of integration of wind and solar PV in a typical power network

Integration of solar PV and wind in to the distribution network is one of the most promising challenges of the modern power system networks to meet the growing demand of energy. Analysis of the effects of solar and wind intermittencies in the network are vital to maintain the power quality. Keeping this in view, this research paper focuses on impact analysis study of a typical power network with hybrid generation: solar PV and wind integration to quantify the level of impacts like power variation and voltage variation in the network through load flow analysis. Initially, a typical network model is developed using PSS-SINCAL and load profile analysis has been carried out based on the typical daily load profile and wind/solar profile to verify the power and voltage variations extensively in the network considering different scenarios. Results of this research analysis can be used as guidelines for utility grid to provide regulated and improved quality of energy supply by implementing appropriate planning of generation reserve and other control measures in the network
