Diameter variations of irregular fibers under different tensions

The cross-section area of animal fibers varies along the fiber length, and this geometrical irregularity has a major impact on the mechanical properties of those fibers. In practice fibers are often subjected to tensile stresses during processing and application, which may change fiber cross-section area. It is thus necessary to examine geometrical irregularity of fibers under tension. In this study, scoured animal fibers were subjected to different tensile loading using a Single Fiber Analyzer (SIFAN) instrument. The 3D images of the fiber specimens were first constructed, and then along-fiber diameter irregularities of the specimens were analyzed for different levels of tensile loading. The changes in effective fineness of the fiber specimens were also discussed. The results indicate that for the wool fibers examined, there is considerable discrepancy in the fiber diameter results obtained from the commonly used single scan along fiber length and that from multiple scans at different rotational angles, and that the diameter variation along fiber length increases as fiber tension increases. The results also show that when diameter reduction treatments are applied to wool by stretching, the reduced average fiber diameter is associated with an increase in both within-fiber and between-fiber diameter variations. So in terms of effective fineness, the change is much smaller than the difference between the average diameters of the parent and treated wool. These results have significant implications for improving the accuracy of fiber diameter measurement and evaluation.

Pathway planning and 'becoming somebody' : Exploring the tensions between wellbeing and credentialism with students at (educational) risk

This paper maps the policy shifts around the education and training of youth that frame how schools respond to issues of youth' at risk'. These shifts have occurred with the move from the self managing schools marked by market discourses of competition, autonomy and image management that supplanted earlier discourses of welfare and community, through to recent policies in Victoria arising from the Kirby Review of Post compulsory Education and Public Education, the Next Generation undertaken by the Labor government. These reports, and the policies emerging out of them, are producing new discourses about youth and schooling focusing on wellbeing, learning networks and more systemic support for schools at the same time as there is increased accountability and expectations of schools. Drawing on the school exclusion literature from the U.K, and using Bourdieu's notion of habitus, we examine the findings from a recent study undertaken on the Geelong Pathways Planning project, funded through a Victorian government strategy, to discuss how schools respond to such initiatives. The project explored the ways in which students in the Geelong region understood and worked with the job planning pathways program, and how service providers (schools, community education facilities, job networks etc) coordinated to meet the needs of individual youth. There was a disjuncture in the participating schools between the discourses of care and welfare for students at risk, and the actual practices and policies that ignored or excluded such students. This paper concludes with a discussion of what might be required systemically, in schools and in their relations to other education providers, to build the capacity to respond more effectively to all students.

Engaging men in men's violence prevention : exploring the tensions, dilemmas and possibilities

The aim of this discussion paper is to raise some questions and to encourage debate about the impact on gender equality of increasing men's involvement in campaigns to end men's violence against women. To address this issue, I have conducted a critical review of the literature on working with men as partners in violence prevention projects. I have also located this literature within theoretical debates about men's privilege, men's interests and men's resistance to change.

Sporting clubs, alcohol and young people : enduring tensions and emerging possibilities

This paper examines data from a research project that investigated the cultural drivers of drinking in 14-24 year-old Australians, funded by Drinkwise Australia and the Department of Health and Ageing. At the same time that we were working on this project a moral panic about young people, risk and binge drinking had once more energised public debate. Prominent here was the highly politicised imputation of a strategic taxation levy on ready to drink products (alcopopos). This qualitative, interview-based project examined two separate but related aspects of young people's alcohol use: the roles played by sporting clubs, as community hubs, in shaping young people's use of alcohol: and young people's drinking biographies over different phases of their lives. This paper will focus on the sporting club study to discuss issues related to the positioning and serving of alcohol in the relation to young people. As part of the study, we conducted interviews with club administrators and young people in a range of sporting clubs. Insights from the study give rise to the potential for clubs to play an active and influential role in helping young people create positive/responsible approaches to alcohol consumption.

Developing the whole child? Tensions between sport and study in Australian independent schools

This paper reports on a research project that set out to examin the relationship between students' involvement in school co-curricular activities and their academic performance.  The warrant for the study emerges out of consistent claims made about the provision of co-curricular, naming sporting, activities and the development of a more rounded and successful student.  The primary question being asked here was: 'Are student's academic performances, as measured by their results for tertiary entrance in their final year of school, improved or reduced by their participation in co-curricular activities?'  The study used a mix of quantitative and qualitative methods to interrogate this relationship.

Exploring tensions in organisational learning : international and postcolonial perspectives

For the past decade I have been engaged as a management consultant in the area of organisational change and development. This has been primarily within international development environments, and all the professional opportunities, challenges and learning they offer. This thesis therefore employs reflexivity to explore professional practices within this context. These practices are primarily considered within the context of an emerging economy dealing with the challenges of globalisation, against a backdrop of tradition and the old vestiges of colonialism and socialism. Of particular interest have been the tensions between humanist and corporate values that emerge when dealing with the people and learning side of organisations, and within a context of what can be broadly defined as 'where west meets east'. These tensions are explored within a values framework and through consideration of some the themes that feature in the area of postcolonial studies. The intention of the study has been to explore some of the meanings and representations that emerge from professional experience, how they are explained and represented, and what the meanings and representations derived might imply in considering the requirements of 'principled' professional practice. The study is built around the work place and the researcher's role within it and therefore draws heavily on personal reflection and reflexivity. The qualitative methodologies employed draw heavily from the literature dealing with critical social science, and in particular that relating to 'narrative inquiry'. Particular consideration is given to the location of self in the research context and the way in which professional knowledge is constructed.

Creative tensions? Creativity and basic skills in recent educational policy.

Recently, in response to sustained criticism about the standards driven curriculum, UK government agencies have been promoting creativity in schools. In this article we explore how creativity is being defined in current national educational policy statements; how these definitions relate to other theoretical work on creativity, and the implications for the curriculum and pedagogies.

Ethical tensions and academic leaders

Internationally universities have been characterized by shrinking government funding, fierce competition for student enrolments, and greater pressures to become commercially viable. It is against this complex background that academic leaders have been required to confront and resolve a magnitude of conflicting interests as they seek to balance a variety of values in their decision-making processes. In this article we put forward a model of ethical decision-making developed from empirical research and literature. To test the efficacy of the model, a case scenario is posed. The article concludes by raising a number of implications for academic leaders regarding ongoing professional learning needed in this area.

'Smart' technologies in early years literacy education: a meta-narrative of paradigmatic tensions in iPad use in an Australian preparatory classroom

With the revolution that has taken place in the functionality and uptake of portable networked ‘smart’ technologies, educators are looking to see what potential applications such technologies might have for school education. This article reports on a study into the use of portable personal computing devices in the early years of schooling. Specifically, it focuses on emerging patterns of use of Apple iPads in an Australian Preparatory (first year of compulsory schooling) classroom across the first year of implementation of these devices. We draw on student and teacher interviews and classroom observation data to provide a research meta-narrative of the intentions, practices and reflections of a ‘first year out’ teacher, and to discuss points of tension found in the contested space of early years literacy education, which are highlighted when potentially transformative technologies meet institutionalized literacy education practices. Our findings suggest that the broader policy and curriculum context of early years literacy education, and institutionalized practices found in this space, are potentially at odds with teacher-held intentions to transform learning through technology use, particularly with respect to tensions between print-based traditions and new digital literacies, and those between standards-based classroom curricular and more emancipatory agendas.

Tensions in home–school partnerships : the different perspectives of teachers and parents of students with learning barriers

This paper presents the findings of a qualitative study of learning partnerships between teachers and parents of students with learning barriers. The aim was to investigate the beliefs and understandings of parents and teacher participants around roles in partnerships, so as to identify operational processes that support effective collaboration. The study was based on the premise that home–school partnerships have been established as a positive influence on the education of students with learning barriers but tensions exist within these partnerships in practice. In the study it was posited that some tensions stemmed from differences in role understandings between parent and teacher. Data revealed key themes emerging from the case studies. Findings indicated that parents and teachers believed that involvement and partnerships are integral to supporting the learning of students with learning barriers. However, differences emerged as to how teachers and parents constructed and interpreted involvement and operational processes supporting partnerships, and the significance each group placed on different aspects of collaboration between parent and teacher.

Negotiating gender boundaries : tensions in developing a professional identity as a female physical educator in boys' schools

Historically, gendered boundaries and their impacts on education have been widely contested. The global gender policy debate over the last sixty years has significantly vacillated between prioritising issues of educational and social practice that appear to privilege one gender over another (Lingard, Martino & Mills, 2009). The very nature of the title ‘Boys’ school’ conveys a hard gendered boundarying. In a socio-political climate where boys’ supposed underachievement has been attributed to the presumed “feminisation of teaching” (Hoff Sommers, 2000) it is not surprising that the rhetoric around the purpose and intent of boys’ education privileges masculinist discourses and practices. Physical Education (PE) and sport is often implicated as prominent curriculum spaces where the tensions produced through gendered discourse-power relations are played out, often at the expense of marginalised others.
