net sustainability. At best they reduce relative resource consumption. They still consume vast quantities of materials, energy, water and ecosystems during construction. Moreover, green buildings replace land and ecosystems with structures that, at the very best, only 'mimic' ecosystems<'). Mimicking nature is little compensation when we have lost a third of species that are integral parts of our life support system. Already, development has exceeded the Earth's ecological carrying capacity, so even 'restorative' design is not enough. Urban areas must be retrofitted to increase net bioregional carrying capacity - just to support existing or reduced population levels in cities. The eco-retrofitting of our built environment is therefore an essential precondition of achieving a sustainable society. But we need to eco-retrofit cities in ways that increase net sustainability, not just relative efficiency.

The basis of treatment for amblyopia (poor vision due to abnormal visual experience early in life) for 250 years has been patching of the unaffected eye for extended times to ensure a period of use of the affected eye. Over the last decade randomised controlled treatment trials have provided some evidence on how to tailor amblyopia therapy more precisely to achieve the best visual outcome with the least negative impact on the patient and the family. This review highlights the expansion of knowledge regarding treatment for amblyopia and aims to provide optometrists with a summary of research evidence to enable them to better treat amblyopia. Treatment for amblyopia is effective, as it reduces overall prevalence and severity of visual loss in this population. Correction of refractive error alone significantly improves visual acuity, sometimes to the point where further amblyopia treatment is not required. Atropine penalisation and patch occlusion are effective in treating amblyopia. Lesser amounts of occlusion or penalisation have been found to be just as effective as greater amounts. Recent evidence has highlighted that occlusion or penalisation in amblyopia treatment can create negative changes in behaviour in children and impact on family life. These complications should be considere when prescribing treatment because they can negatively affect compliance. Studies investigating the maximum age at which treatment of amblyopia can still be effective and the importance of near activities during occlusion are ongoing.

Genuine sustainability would require that urban development provide net positive social and ecological gains to compensate for previous lost natural capital and carrying capacity. Thus far, green buildings do not contribute to net sustainability. While they reduce relative resource consumption, they consume vast quantities of materials, energy and water.i Moreover, they replace land and ecosystems with structures that, at best, ‘mimic’ ecosystems. Elsewhere, the author has proposed a‘sustainability standard’, where development would leave the ecology, as well as society, better off after construction than before.ii To meet this standard, a development would need to add natural and social capital beyond what existed prior to development. Positive DesignTM or Positive DevelopmentTM is that which expands both the ecological base (life support system) and the public estate (equitable access to means of survival). How to achieve this is discussed in Positive Development (Birkeland 2008). This paper examines how net positive gains can be achieved in a ubtropical as well as temperate environment.

In daily activities people are using a number of available means for the achievement of balance, such as the use of hands and the co-ordination of balance. One of the approaches that explains this relationship between perception and action is the ecological theory that is based on the work of a) Bernstein (1967), who imposed the problem of ‘the degrees of freedom’, b) Gibson (1979), who referred to the theory of perception and the way which the information is received from the environment in order for a certain movement to be achieved, c) Newell (1986), who proposed that movement can derive from the interaction of the constraints that imposed from the environment and the organism and d) Kugler, Kelso and Turvey (1982), who showed the way which “the degrees of freedom” are connected and interact. According to the above mentioned theories, the development of movement co-ordination can result from the different constraints that imposed into the organism-environment system. The close relation between the environmental and organismic constraints, as well as their interaction is responsible for the movement system that will be activated. These constraints apart from shaping the co-ordination of specific movements can be a rate limiting factor, to a certain degree, in the acquisition and mastering of a new skill. This frame of work can be an essential tool for the study of catching an object (e.g., a ball). The importance of this study becomes obvious due to the fact that movements that involved in catching an object are representative of every day actions and characteristic of the interaction between perception and action.

This paper proposes adolescence as a useful concept rather than definitive. It explores the notion of adolescence and its relevance to contemporary society and schooling. We reflect on the purposes for the emergence of research into adolescence during the early 20th century, particularly the particular scientific and societal pressures that served to bring this field to prominence. Recent debate has started to problematise many of the early parameters used to define and provide bounds for understanding adolescents and adolescent experience and for the rationale for some notionally tailored educational contexts. This paper provides an overview of this debate and argues for a reconsideration of some of the basic tenets for definition. In particular we discuss the cultural construction of adolescence in the light of our new globalised society. A possibility for thinking about contemporary adolescents is by considering them in terms of generational characteristics. What makes a new generation? Typically, members of a generation share age, a set of experiences during formative years, and a set of social and economic conditions. The adolescents of today fall into the group known collectively as the ‘Y Generation’, the ‘D (digital) Generation’, Generation C (consumer) and the ‘Millennial’s’. Born after mid-1980, they are characterised as computer and internet competent, multi-taskers, with a global perspective. They respond best to visual language, and are heavily influenced by the media. We consider the generational traits and how this impacts on the teaching and learning.

The epilogue pulls together the conceptual and methodological significance of the papers in the special issue exploring childhood and social interaction in everyday life in Sweden, Norway, United States and Australia. In considering the special issue, four domains of childhood are identified and discussed: childhood is a social construct where children learn how to enter into and participate in their social organizations, competency is best understood when communicative practices are examined in situ, children’s talk and interaction show situated culture in action, and childhood consists of shared social orders between children and adults. Emerging analytic interests are proposed, including investigating how children understand locations and place. Finally, the epilogue highlights the core focus of this special issue, which is showing children’s own methods for making sense of their everyday contexts using the interactional and cultural resources they have to hand.

Objective: The present study sought to identify the work destinations of graduates and ascertain their perceived preparedness for practice from a regional occupational therapy program, which had been specifically developed to support the health requirements of northern Australians by having an emphasis on rural practice. ---------- Design: Self-report questionnaires and semistructured in-depth telephone interviews. ---------- Participants: Graduates (n = 15) from the first cohort of occupational therapists from James Cook University, Queensland. ---------- Main outcome measure: The study enabled comparisons to be made between rural and urban based occupational therapists, while the semistructured interviews provided a deeper understanding of participants' experiences regarding their preparation for practice. ---------- Results: Demographic differences were noted between occupational therapists working in rural and urban settings. Rural therapists were predominantly younger and had worked in slightly more positions than their urban counterparts. The study also offered some insights into the value that therapists placed on the subjects taught during their undergraduate occupational therapy training, and had highlighted the differences in perceptions between therapists with rural experience and those with urban experience regarding the subjects that best prepared them for practice. Generally, rural therapists reported that all subjects included in the curriculum had equipped them well for practice. ---------- Conclusions: Findings suggest the need to undertake further research to determine the actual nature of rural practice, the personal characteristics of rural graduates and the experiences of students while on rural clinical placements.

The Co-operative Research Centre for Construction Innovation (CRC-CI) is funding a project known as Value Alignment Process for Project Delivery. The project consists of a study of best practice project delivery and the development of a suite of products, resources and services to guide project teams towards the best procurement approach for a specific project or group of projects. These resources will be focused on promoting the principles that underlie best practice project delivery rather than simply identifying an off-the-shelf procurement system. This project builds on earlier work by Sidwell, Kennedy and Chan (2002), on re-engineering the construction delivery process, which developed a procurement framework in the form of a Decision Matrix

Background The accurate measurement of Cardiac output (CO) is vital in guiding the treatment of critically ill patients. Invasive or minimally invasive measurement of CO is not without inherent risks to the patient. Skilled Intensive Care Unit (ICU) nursing staff are in an ideal position to assess changes in CO following therapeutic measures. The USCOM (Ultrasonic Cardiac Output Monitor) device is a non-invasive CO monitor whose clinical utility and ease of use requires testing. Objectives To compare cardiac output measurement using a non-invasive ultrasonic device (USCOM) operated by a non-echocardiograhically trained ICU Registered Nurse (RN), with the conventional pulmonary artery catheter (PAC) using both thermodilution and Fick methods. Design Prospective observational study. Setting and participants Between April 2006 and March 2007, we evaluated 30 spontaneously breathing patients requiring PAC for assessment of heart failure and/or pulmonary hypertension at a tertiary level cardiothoracic hospital. Methods SCOM CO was compared with thermodilution measurements via PAC and CO estimated using a modified Fick equation. This catheter was inserted by a medical officer, and all USCOM measurements by a senior ICU nurse. Mean values, bias and precision, and mean percentage difference between measures were determined to compare methods. The Intra-Class Correlation statistic was also used to assess agreement. The USCOM time to measure was recorded to assess the learning curve for USCOM use performed by an ICU RN and a line of best fit demonstrated to describe the operator learning curve. Results In 24 of 30 (80%) patients studied, CO measures were obtained. In 6 of 30 (20%) patients, an adequate USCOM signal was not achieved. The mean difference (±standard deviation) between USCOM and PAC, USCOM and Fick, and Fick and PAC CO were small, −0.34 ± 0.52 L/min, −0.33 ± 0.90 L/min and −0.25 ± 0.63 L/min respectively across a range of outputs from 2.6 L/min to 7.2 L/min. The percent limits of agreement (LOA) for all measures were −34.6% to 17.8% for USCOM and PAC, −49.8% to 34.1% for USCOM and Fick and −36.4% to 23.7% for PAC and Fick. Signal acquisition time reduced on average by 0.6 min per measure to less than 10 min at the end of the study. Conclusions In 80% of our cohort, USCOM, PAC and Fick measures of CO all showed clinically acceptable agreement and the learning curve for operation of the non-invasive USCOM device by an ICU RN was found to be satisfactorily short. Further work is required in patients receiving positive pressure ventilation.

From an initial sample of 747 primary school students, the top 16 percent (n =116) with high self-esteem (HSE) and the bottom 15 percent (n = I1 I) with low selfesteem (LSE) were se/eeted. These two groups were then compared on personal and classroom variables. Significant differences were found for all personal (self-talk, selfconcepts) and classroom (teacher feedback, praise, teacher-student relationship, and classroom environment) variables. Students with HSE scored more highly on all variables. Discriminant Function Analysis (DFA) was then used to determine which variables discriminated between these two groups of students. Learner self-concept, positive and negative self-talk, classroom environment, and effort feedback were the best discriminators of students with high and low self-esteem. Implications for educational psychologists and teachers are discussed.

Thirty-five clients who received counseling participated in this exploratory study by completing a letter to a friend that described in as much detail as possible what they had learned from counseling. The participants’ written responses were analyzed using a content analysis approach. The analysis indicated that the data were best categorized in terms of three broad areas of learnings (Self, Relations with Others, and the Process of Learning and Change). The Self taxonomy was found to consist of six hierarchical levels. The Relations with Others taxonomy consisted of five hierarchical levels, while the Process of Learning and Change taxonomy consisted of five hierarchical levels. The results suggested that these three taxonomies offer a promising and exciting way to view the impact of counseling within a learning framework. If these taxonomies are found to be stable in future research and clients are easily classified using the taxonomies then this approach may have implications for counseling. It may well be that to maximise the learnings counselors could use specific strategies and techniques to enhance their clients’ learning in the three areas.

Resolving insurance disputes can focus only on quantum. Where insurers adopt integrative solutions they can enjoy cost savings and higher customer satisfaction. An integratively managed process can expand the negotiation options. The potential inherent in plaintiff’s emotions to resolve matters on an emotional basis, rather than an economic one, is explored. Using research, the author demonstrates how mediations are more likely to obtain integrative outcomes than unmediated conferences. Using a combination of governmental reports, published studies and academic publications, the paper demonstrates how mediation is more likely to foster an environment where the parties communicate and cooperate. Research is employed to demonstrate where mediators can reduce hostilities, in circumstances where negotiating parties alone would likely fail. Generally the paper constructs an argument to support the proposition that mediation can offer insurers an effective mechanism to reduce costs and increase customer satisfaction. INTRODUCTION Mediation can offer insurers an effective mechanism to reduce costs and increase customer satisfaction. This paper will first demonstrate the differences between distributive and integrative outcomes. It is argued insurer’s interest can be far better served through obtaining an integrative solution. The paper explains how the mediator can assist both parties to obtain an integrative outcome. Simultaneously the paper explores the extreme difficulties conference participants face in obtaining an integrative outcome without a mediator in an adversarial climate. The mediator’s ability to assist in the facilitation of integrative information exchange, defuse hostilities and reality check expectations is discussed. The mediator’s ability to facilitate in this area is compared to the inability of conference participants to achieve similar results. This paper concludes, the potential financial benefit offered by integrative solutions, combined with the ability of mediation to deliver such outcomes where unmediated conferences cannot deliver, leads to the recommendation that insurers opt for a mediation to best serve their commercial interests.

This feasibility study was established to investigate the application of the concept of ‘best value’ in construction procurement in Australia. In the case of ‘best value’ in the business enterprise, ‘best value’ is that which returns greatest value to the business enterprise’s shareholders. However, in the case of the public sector, ‘best value’ is more complex. For that reason, this research project focuses mainly on public sector construction project procurement.
