Concentric left ventricular morphology in aerobically trained kayak canoeists

The aim of the present study was to test the hypothesis that upper body aerobically trained athletes (kayak canoeists) would have greater left ventricular wall thickness, but similar left ventricular diastolic chamber dimensions, compared with recreationally active and sedentary men. Ultrasound echocardiography was used to determine cardiac structure and function in highly trained kayak canoeists (n?=?10), moderately active (n?=?10) and sedentary men (n?=?10). The septal and posterior left ventricular walls were ～0.2?cm thicker in kayak canoeists (P?<?0.05), and left ventricular mass was 51% and 32% greater (P?<?0.05) in canoeists than in the sedentary and moderately trained participants, respectively. There were no differences in left ventricular chamber dimension, suggesting that the kayak canoeists had a concentric pattern of left ventricular adaptation to aerobic upper body training. Scaling the data to body composition indices had no effect on the outcome of the statistical analysis. There were no differences in resting Doppler left ventricular diastolic or systolic function among the groups. Ejection fraction was lower in the kayak canoeists, but the magnitude of the difference was within the normal variability for this measurement. Thus aerobically upper body trained athletes demonstrated a concentric pattern of cardiac enlargement, but resting left ventricle function was not different between athletes, moderately active and sedentary individuals.     

Economic rationalism and the politics of education in Australia

Until the mid‐1970s, the politics of urban school desegregation concentrated almost exclusively on the attainment of some form of racial balance. The racial balance paradigm became the focal point for desegregation planners and for local, state and national dispute about ‘forced bussing’. However, in its 1977 Milliken II ruling, the Supreme Court added critical new elements to the urban school desegregation paradigm. By affirming a desegregation plan which included remedial education components in all‐minority schools, and which required state participation in financing these components, Milliken II heralded a new era of urban school desegregation. Resource issues and school effectiveness issues joined racial balance issues in the crucible of desegregation politics. In this chapter, the post‐Milliken politics of urban school desegregation are highlighted through examination of the St Louis and Kansas City cases. New goals, new issues, new alignments of interests and new political strategies are apparent, presenting new challenges to students of urban education policy and politics.     

Beyond the Bounds of Thought: Speculative Philosophy and the Last Proposition of the Tractatus

Wittgenstein's Tractatus attempts to characterize, via an account of the meaning and truth of propositional expressions, the limits to human thought. It turns out that not only, according to him, are the limits to human thought something which lie outside the capacity for humans to express, but such a notion is strictly speaking without sense. He concludes the book with the sentence "What we cannot speak about we must pass over in silence." Whitehead, on the contrary, is concerned to suggest that human sentential expressions are always inadequate to the thoughts which we wish to express. Nonetheless he suggests that a happy speculation a la Plato might just be right, even though we may never know that it is. This paper argues that there are no convincing arguments that either Wittgenstein or Whitehead is right here. So it is best that we maintain an agnostic position with respect to the view that human thought is strictly limited or that no adequate expressions of our thoughts can be found. Both educationally and practically, failing of any convincing arguments to the contrary, it is better that we presuppose, along with the mediaeval Christian thinkers, that our reason and insight are sufficient to the task of ultimately penetrating into the mysteries of the world, however difficult that task might be. Thus a happy speculation with no grounding is a perfectly good thing to engage in. It just might be true.     

Turnaround as Reform: Opportunity for Meaningful Change or Neoliberal Posturing?

This study explores the neoliberal agenda of turnaround school reform efforts in America by examining the application and transformation of a Midwest State Turnaround Schools Project for the public school system. Perceptions of administrators and state-level policy actors are considered. Data were collected from 13 participants during the implementation of the statewide turnaround program and the analysis focused on the neoliberal ideology during the implementation of the State Turnaround Schools Project. Corporate infiltration and funding leverage reflect the sticky web of policymakers and private corporations and their influence. District communication, support, and shared accountability underscore important lessons in leadership for turnaround school programs. Successful schools transformed the turnaround policy implementation by involving communities and restructuring their school district. However, the neoliberal agenda revealed the impact of government labeling, restructuring, and reallocating resources for under-performing schools and unveiling the infiltration of private corporations behind turnaround policy and student achievement. This alarming finding points to how turnaround school policy implementation weakens control of democratically elected authorities and stagnates critical thinking that challenges the interests behind turnaround school policy.     

Implementing Online Counselling in Australian Secondary Schools: What Principals Think

Today’s young people have integrated the online world into their everyday reality and schools have generally accepted the importance of technology in the education process. However, there has been limited use in schools of technology to counsel young people, although early indications suggest that school counsellors may be prepared to offer synchronous online counselling if they were supported by school principals. The aim of this study was to investigate Australian secondary school principals’ views about using an online format for counselling in schools. There were 33 principals who participated and they indicated technological competency and acknowledged the benefits of using technology in the counselling process. The principals were generally supportive of the provision of online school counselling, although their major concern was the need for more counsellors and the impact on the workload of current counselling staff. A few principals, however, were unconvinced about offering online counselling and had a fundamental preference for face-to-face communication experiences for students. Strategies for facilitating the acceptance of online counselling by principals and guiding implementation in schools are proposed.     

Licencing and training reform in the Australian aircraft maintenance industry

The training and licencing of aircraft maintenance engineers fulfils a crucial protective function since it is they who perform and supervise aircraft maintenance and certify that planes are safe afterwards. In Australia, prior to training reform, a trades-based system of aircraft maintenance engineer training existed in an orderly relation with the system of licencing, regulated by the Civil Aviation Safety Authority (CASA). Training reform through the 1990s gave rise to concerns that the training system could not be relied upon to deliver adequate numbers of trainees with valid qualifications. From 2007, CASA introduced new regulations, designed to align Australia’s qualifications and licencing with the European Aviation Safety Agency (EASA). This process saw the aviation regulator effectively cede much quality control of training to an increasingly dysfunctional training system, giving rise to doubts about whether Australia’s international obligations for quality aircraft maintenance training can be fulfilled.     

Personal understanding of assessment and the link to assessment practice: the perspectives of higher education staff

The study investigates how higher education staff understand assessment, and the relationship between these understandings and their assessment practices. Nine individuals attended a workshop that guided them through the creation of a concept map about assessment, which was subsequently discussed in one-to-one semi-structured interviews. We found considerable variation in understanding of assessment, both between and within participants, and this appeared to be a consequence of the varied contexts within which assessment operates. Some assessment practices were highly complex, and at times closely entwined with teaching. In addition, individuals’ practices helped to illuminate variation in how underlying concepts (e.g. assessment for learning) were understood. The approach supported the construction of the participants’ understanding of assessment, and enabled the exploration of the interplay between thinking and reported practice, which were closely aligned. It also drew attention to the need to further develop methodologies which capture both the complexity of thinking about assessment and real-world assessment practices.     

Cetacean Frustration: The Representation of Whales and Dolphins in Picture Books for Young Children

To enable children to develop towards becoming part of the solution to environmental problems, it is essential that they are given the opportunity to become familiar with the natural world from early childhood. Familiarity is required to develop understanding of, care for and, ultimately, action in terms of protecting the natural world. As adult-led reading of picture books is a common form of indirect exposure to the natural world for young children, this study examines the biological accuracy of the representation of whales and dolphins in the images and text of picture books. Of the total of 116 books examined, 74 (63.8?%) had errors in the representation of cetaceans in the images and/or text. Errors were identified in both fictional (mean?=?8.0 errors/book, SD?=?11.1, n?=?55) and non-fictional (mean?=?2.3 errors/book, SD?=?4.9, n?=?61) books. The potential impact of the errors is discussed, and suggestions are made as to how the impact could be reduced and how the biological accuracy of picture books could be improved.
