Children and consent to medical treatment

This chapter provides a comprehensive and up-to-date treatment of legislative provisions and common law principles regarding children and the law of consent to medical treatment. When can children provide their own consent? Can parents consent on behalf of their children, and if so, under what circumstances and why? Is court authority ever required, and if so, when, and why? What new contexts are providing fresh challenges to legal principles, parents, medical practitioners, and most importantly, children?

Integrating ‘role play’ in assessment to strengthen professional conduct and accountability of students : a pilot study

BACKGROUND In a process engineering setting, graduates are frequently allocated reviews of existing operations or required to scope new production processes by their supervisors with a view to improving or expanding on operations and overall productivity. These tasks may be carried out in teams and in consultation with the process engineer’s immediate line manager or a more experienced engineer, such as the Production or Maintenance Manager; ultimately reporting to senior management, which is frequently a non-engineer. Although professional skills development is part of engineering curricula, ‘professional conduct’ and ‘accountability’ required for dealing with peers and superiors in industry is not very well addressed at university. Consequently, upon graduation, many students are, in terms of knowledge and experience in this area, underprepared to work effectively in industry settings. PURPOSE The purpose of this study was to develop and implement a role-play scenario within a core 2nd year process engineering unit, so that students could gain knowledge, skills and experience in different aspects (and nuances) of professional conduct and accountability. DESIGN/METHOD In the role-play scenario, students worked in ‘engineering production teams’ to design a process for an iconic Queensland fruitcake and to present their solution and recommendations (culminating in a poster presentation) to an assessment panel consisting of staff, role-playing as, ‘production and plant managers’. Students were assessed on several areas, including professionalism using a criteria referenced assessment guide by a 3-member cross-disciplinary staff panel consisting of a Business Faculty lecturer, an engineer from industry and the lecturer of the Process Engineering unit. Professional conduct and accountability was gauged through direct questioning by the panel. Feedback was also sought from students on various aspects through a survey questionnaire after the role play activity at the end of semester. RESULTS Overall, the role play was very well performed with students achieving an average score of 79.3/100 (distinction grade). Professional conduct as assessed by panel was on average better than scores given for professional accountability (4.0 compared with 3.6 out of 5). Feedback from students indicated that the learning activities had contributed to their overall understanding of the content and the role of process engineers. Industry involvement was rated very highly as contributing to their learning at 4.8 (on Likert scale from 1 – 5) and the poster presentation was rated at 3.6. CONCLUSIONS This pilot study was successful in implementing a new assessment task for modelling professional conduct and accountability within a 2nd year core unit. This task incorporated a role-play activity and there was evidence to suggest that this and associated learning tasks were successful in broadening students’ understanding and skills in this area required for engineering practice. Following feedback given by students and staff, improvements will be made to the nature of the problem, how it is defined, its assessment, and the approach taken in the role-play scenario when the unit is offered in 2014.

Modes of criminal justice, indigenous youth and social democracy

The political question of how the will of a community is to be democratically formed and adhered to, the question of social democracy, is normatively tied to the mode of criminal justice employed within that democratic public sphere. Liberal, republican, procedural and communitarian forms of democratic will-formation respectively reflect retributive,restorative, procedural and co-operative modes of criminal justice. After first elaborating these links through the critical response of republican and procedural theories of democracy to the liberal practice of democratic will-formation and its retributive mode of justice, our discussion considers the recent practice of restorative and procedural justice with respect to Indigenous youth; and this in the context of a severely diminished role for Indigenous justice agencies in the public sphere. In light of certain shortcomings in both the restorative and procedural modes of justice, and so too with republican and procedural understandings of the democratic public sphere, we turn to a discussion of procedural communitarianism, anchored as it is in Dewey’s notion of social co-operation. From here we attempt a brief formulation of what a socially co-operative mode of justice might consist of; a mode of justice where historically racial and economically coercive injustices are sufficiently recognised.

Aesthetics of urban media façades

This paper sets out to develop and extend current literature on design practices for ambient media façades. It does this by bringing together theories of ambient media, computational aesthetics, and urban aesthetics. This unique theoretical combination has informed the design of several exemplars produced by the author, which are discussed as case studies.

Effects of pupil center shift on ocular aberrations

Purpose: To investigate effects of pupil shifts, occurring with changes in luminance and accommodation stimuli, on refraction components and higher-order aberrations. Method: Participants were young and older groups (n=20, 22±2 years, age range 18–25 years; n=19, 49±4 years, 45–58 years). Aberrations/refractions at 4 mm and 3 mm diameters were compared between centered and decentered pupils for low (background 0.01cd/m², 0D), and high (6100cd/m², 4D or 6D) stimuli. Decentration was the difference between pupil centers for low and high stimuli. Clinical important changes with decentration were: M ±0.50D or ±0.25D, J180 and J45 ±0.25D or ±0.125D, HORMS ±0.05m, C(3, 1) ±0.05m, C(4, 0) ±0.05m. Results: Because of small pupil shifts in most participants (mean 0.26mm), there were few important changes in most refraction components and higher-order aberration terms. However, M changed by >0.25 D for a third of participants with 4mm pupils. When determining refractions from 2nd-6th order aberration coefficients, the more stringent criteria gave 76/ 534 (14%) possible important changes. Some participants had large pupil shifts with considerable aberration changes. Comparisons at the high stimulus were possible for only 11 participants because of small pupils. When refractions were determined from 2nd order aberration coefficients only, there were only 35 (7%) important changes for the more stringent criteria. Conclusion: Usually pupil shifts with changes in stimulus conditions have little influence on aberrations, but they can with high shifts. The number of aberrations orders that are considered as contributing to refraction influences the proportion of cases that might be considered clinically important.

Reconciliation and Early Childhood Education for Sustainability : Broadening the Environmental Paradigm

The uptake of sustainability initiatives in early childhood education curricula continues to gain momentum in Australia and internationally. Growing awareness about the fragility of natural environments in local and global contexts, along with prioritising sustainability in educational policy, has resulted in more broad-scale responses to sustainability in early years settings. To address issues of sustainability, many childcare centres and schools focus on environmental initiatives such as garden projects, recycling and water conservation. While important, such initiatives respond to just one dimension of sustainability. With expanding focus on sustainability initiatives in early childhood education, it is timely to consider why the environmental dimension receives the most attention and what this means for social, political and economic areas of concern.

Multi-modal deformable medical image registration

Non-rigid image registration is an essential tool required for overcoming the inherent local anatomical variations that exist between images acquired from different individuals or atlases. Furthermore, certain applications require this type of registration to operate across images acquired from different imaging modalities. One popular local approach for estimating this registration is a block matching procedure utilising the mutual information criterion. However, previous block matching procedures generate a sparse deformation field containing displacement estimates at uniformly spaced locations. This neglects to make use of the evidence that block matching results are dependent on the amount of local information content. This paper presents a solution to this drawback by proposing the use of a Reversible Jump Markov Chain Monte Carlo statistical procedure to optimally select grid points of interest. Three different methods are then compared to propagate the estimated sparse deformation field to the entire image including a thin-plate spline warp, Gaussian convolution, and a hybrid fluid technique. Results show that non-rigid registration can be improved by using the proposed algorithm to optimally select grid points of interest.
