This article reports on a qualitative research project conducted in Victoria, Australia, with nine older women. The purpose of the research was to explore the women's experience of involvement in craft groups, and specifically, the impact of this involvement on their sense of well-being. Traditionally the health of older people has been examined in relation to medical markers of physical well-being, and often, decline. We were interested to widen this perspective to understand the impact of social connection, belonging and ongoing learning and development on the ageing experience. While the focus of the groups was on domestic craftwork, the process of coming together as a collective appeared to have significant bearing on the holistic health of the women involved. Consistent with feminist groupwork literature, the findings indicated that the women we interviewed experienced the group setting as affirming and generative in a number of ways. These include providing an avenue for mutual aid, addressing isolation, affirming individual and collective strength and wisdom, while acquiring new skills, and normalising concerns regarding health and family.

The study investigated two main questions: the first focused on the factors that enabled and constrained student teachers' engagement of a socially critical pedagogy in physical education teacher education (PETE); the second centered on gaining insight into the usefulness of knowledgeability as a concept for analysing student teachers engagement of a socially critical pedagogy. At the time of writing this thesis empirical analyses of socially critical pedagogies in physical education were rare in the educational literature. The study provided an alternative way of analysing student teachers’ engagement of a socially critical pedagogy in PETE. Alternative in that it avoided recycling and reproducing the dualism between agency and structure (Aronowitz and Giroux, 1985) that is prevalent in much of the physical education literature. Conversational interviews were conducted with four student teachers and their teacher educators throughout the duration of a one-semester PETE unit in an Australian university. Observations were made of the lecture and practical sessions and a document analysis was conducted of all unit learning resources. The analytical frame used in the study was structuration theory (Giddens, 1979, 1984). This framework was useful because it gave primacy to the duality of structure which recognised ‘the structural properties of social systems are both the medium and outcome of practices that constitute those systems’ (Giddens, 1979, p.69). The pedagogical intentions of the teacher educator co-ordinating the PETE unit were to change the orientations of the student teachers towards primary school physical education by encouraging them to adopt different ‘lenses’ through which to examine pedagogical practices. These ‘lenses’ highlighted the questions central to those with socio-critical intentions, eg. power, social injustice and diversity. Data generated from conversations with, and observations of, the student teachers, indicated that the actualisation of the teacher educator's intentions were somewhat limited. Despite this, adopting structuration theory as the explanatory framework for the study proved generative at a number of levels. Broadly, structuration theory was useful because it highlighted the way that student teachers' engagement with a socially critical pedagogy is contingent upon particular (idiosyncratic) dialectics of agency and structure. Using the duality of structure as an analytical tool illustrated the way student teachers' were influenced by structural factors as well as the way these structural factors were in turn constituted by the action of the student teachers. Also, by utilising structuration theory as an explanatory framework, the concept of knowledgeability was identified as a useful concept for analysing student teachers' engagement with a socially critical pedagogy in PETE. What is more, the study highlighted the reflexivity of the self and social knowledge, both characteristics of late modernity, as being integral to the way the student teachers engaged with the socially critical pedagogy of EAE400. Not only did the study highlight the reflexivity of the self but it also provided insight into the reflexivity of social knowledge. Much of the socially critical work in physical education implicitly adopts a linear approach to change. Given the findings of the study it might be useful for future developments to consider change as circular. The thesis concludes by suggesting that given the reflexivity of social knowledge, socially critical perspectives might be more readily engaged if the PETE content was incorporated into student teachers existing knowledge frameworks rather than viewed as a replacement for such frameworks.

This study explores the peer group understandings of five male friends between the ages of six and eight years and seeks to examine the ways in which the group’s social dynamics interact to define, regulate and maintain dominant and collective understandings of masculinities. Within a self-selected affinity context, and drawing on their lived and imagined experiences, the boys’ enact and interpret their social worlds. Adopting the principles of ethnography within a framework of feminist poststructuralism and drawing on theories of ‘groupness’ and gender(ed) embodiment, the boys’ understandings of masculinities are captured and interpreted. The key analytic foci are directed towards examining the role of power in the social production of collective schoolboy knowledges, and understanding the processes through which boys subjectify and are subjectified, through social but also bodily discourses. The boys’ constructions of peer group masculinities are (re)presented through a narrative methodology which foregrounds my interpretation of the group’s personal and social relevances and seeks to be inductive in ways that ‘bring to life’ the boys’ stories. The study illuminates the potency of peer culture in shaping and regulating the boys’ dominant understandings of masculinity. Within this culture strong essentialist and hierarchical values are imported to support a range of gender(ed) and sexual dualisms. Here patriarchal adult culture is regularly mimicked and distorted. Underpinned by constructions of ‘femininity’ as the negative ‘other’, dominant masculinities are embodied, cultivated and championed through physical dominance, physical risk, aggression and violence. Through feminist poststructural analysis which enables a theorising of the boys’ subjectivities as fluid, tenuous and often characterised by contradiction and resistance, there exists a potential for interrupting and re-working particular masculinities. Within this framework, more affirmative but equally legitimate understandings and embodiments can be explored. The study presents a warrant for working with early childhood affinity groups to disrupt and contest the dominance and hierarchy of peer culture in an effort to counter-act broader gendered and heterosexist global, state and institutional structures. Framing these assertions is an understanding of the peer context as not only self-limiting and productive of hierarchies, but enabling and generative of affirmative subjectivities.

My thesis is made up of words and images. This study investigates the way in which silence operates productively within and between the two modes of communication. I suggest that in the process of changing words into images or scripto-visual art-practice, the silence in women's lives can be articulated. I argue that women draw on the generative qualities of silence to create forms of speech that override the cultural constructions of gender which have placed them within the space of ‘mute’ silence. To gain an historical perspective of this practice by women, I consider the lives of medieval nuns within religious enclosure and their work with words and images in the illuminated manuscript. I make a comparative study of original illuminated manuscripts, focussing mainly on visual language and locating aspects of the work closest to my own art-practice: the visual treatment of the space and inter-textual components of the page or folio. This project does not include an examination of miniatures or historiated initials. Rather, its aim is to identify and compare the use of other aesthetic devices available to the medieval scribe/artist through which they might have interacted with the text. I suggest links between verbal and visual performances of language and the repetition, or copying of texts by medieval nuns, as a means of female embodiment of words and their spaces. From the outcomes of my studio investigations and my consideration of other contemporary feminist art practices, I demonstrate how women artists may ‘re-write’ the text and ‘speak’ their silence through visual language and the acts of writing, drawing and painting the words of others. Through my engagement with feminist critical theory, the work of medieval scholars, original illuminated manuscripts and my studio research, I propose that scripto-visual practice remains particularly significant for women despite the differences between the medieval period and our own. As a generative practice, it negotiates some of the societal constraints on women's speech and visibility, because its language is ‘silent and disembodied’ from the image of woman constructed by male discourse. It is a form of speech that acknowledges as it defies the social and cultural conditions that shaped its necessity, articulating an alternative voice of women in the space of words and images.

The research challenged traditional notions of the transcendental sublime by identifying the material basis of the experience through the practice of painting. Material interaction within the creative process revealed new insights, illuminated through the sublime experience. The sublime was indicated as a materially-based, generative experience mediating between subject and world.

The thesis points to the emergence of a series of distinctive tensions which were informed by the author's position as a Western male researcher living in Japan, and the changing perceptions of what occured as notions of 'empowerment' and 'voice' touched the 'grounded' data. It argues that the generative narrative(s) constitutes a form of ongoing 'conversation' which succeed in producing an unstructured reading or pedagogy. Although the research does not achieve tangible liberatory outcomes, the generative narrative(s) provides the lens through which to view the student 'resistance' and, as such, permits the examination of an instance of student 'resistance' in Japan.

This paper will examine Kristeva’s conceptions of revolution and revolt to demonstrate the significance of her work for practitioners and researchers working in the emerging field of creative arts practice as research, a field of research that is burgeoning in the UK, Australia, Canada and Scandinavia. I will argue that Kristeva’ thought elaborates the aesthetic underpinnings of discovery and provides a rationale for the methodologies used in artistic research.

In her later work on interpretation, Kristeva places a greater emphasis on the need for analysis or theory, since the art and culture of revolt produce unfamiliar or mutant meanings that are difficult for audiences to grasp in terms of their potency for engendering social change and individual empowerment. However, she places the responsibility for this analysis and interpretation on the art critic. But what if (as is the case with the advent of artistic practice as research), the maker and the “critic” become one and the same? Can this shift in the status of artistic practice within the knowledge economy, be understood in terms of Kristeva account of the sense and nonsense of revolt? I will address these questions by revisiting aspects of Kristeva thinking on experience-in practice and examining her more recent and extended elaboration of revolutionary practice. The paper will explore how her thinking can provide practitioners with a framework for understanding creative arts research as the production of new knowledge. If as Kristeva argues, that art and literature are amongst the few means of revolt and renewal, it seems appropriate to turn to her thinking in order to articulate a rationale and argument for claiming that practice as research can operate as a driver of change and innovation in contemporary culture.

The first part of this task will involve tracing what Kristeva sees as three forms of revolt made possible through aesthetic experience. This will involve a closer examination of the notions of transgression and art as experience. Following on from this discussion, I will discuss how Kristeva’s work constitutes both an implicit and explicit critique of science allowing us to conceive of artistic research as an alternative and performative production of knowledge. Finally in this paper, I will apply and illustrate these ideas through an analysis of a selection of a number of research projects successfully completed by artistic researchers in Australia. I hope to show that artistic practice as a mode of enquiry, reveals the inextricable and necessary relationship between practice and theory, interpretation and making, art and life. I suggest that it is this interrelationship, that underpins what Kristeva describes as creative and revolutionary practice. In the context of creative arts practice as research, Kriteva’s account of experience–in-practice indicates that interpretation and analysis must fall to the practitioner-researcher himself or herself - rather than to another person who has been external to the procedures of making - to trace the significant experiential, subjective and emergent processes involved in the production of the work that allows it to reveal the new. This is necessary if the generative and revolutionary impact of artistic research is to be fully understood in the wider research arena.

Constraint based tools for architectural design exploration need to satisfy aesthetic and functional criteria as well as combine discrete and continuous modes of exploration. In this paper, we examine the possibilities for stochastic processes in design space exploration.

Specifically, we address the application of a stochastic wind motion model to the subdivision of an external building envelope into smaller discrete components. Instead of deterministic subdivision constraints, we introduce explicit uncertainty into the system of subdivision. To address these aims, we develop a model of stochastic wind motion; create a subdivision scheme that is governed by the wind model and explore a design space of a facade subdivision problem. A discrete version of the facade, composed of light strips and panels, based on the bamboo elements deformed by continuous wind motion, is developed. The results of the experiments are presented in the paper.

Within the context of ERA, this paper addresses the question of how we might provide practitioners with a framework for understanding creative arts research as the production of new knowledge. Drawing on the thought of Julia Kristeva, it examines the aesthetic underpinnings of discovery and the implications and significance of this for research training and the development of more effective pedagogies both within and beyond the university.
Kristeva’s work constitutes both an implicit and explicit critique of science allowing us to conceive of artistic research as an experiential and performative production of knowledge. As a mode of enquiry, artistic practice reveals the inextricable and necessary relationship between practice and theory, interpretation and making, art and life. This interrelationship underpins the aesthetic dimension of revolutionary practice and its production of unfamiliar or mutant forms of knowledge that is often difficult to grasp in terms of its capacity to engender social change and innovation. In the context of creative arts practice as research, the notion of experience-in-practice indicates that interpretation and analysis must fall to the practitioner-researcher, himself or herself, rather than to another person who has been external to the procedures of making, to trace the significant experiential, subjective and emergent processes involved in the production of the work that allows it to reveal the new. This is necessary if the generative and revolutionary impact of artistic research is to be fully understood in the wider research arena. In the final part of this paper, I will apply and illustrate these ideas through an analysis of a number of artistic research projects successfully completed in Australia.

There is growing concern about falling levels of student engagement with school science, as evidenced by studies of student attitudes, and decreasing participation at the post compulsory level. One major response to this, the Australian School Innovation in Science, Technology and Mathematics (ASISTM) initiative, involves partnerships between schools and community and industry organisations in developing curriculum projects at the local level. This project fulfils many of the conditions advocated to engage students in learning in the sciences. ASISTM is underpinned by the notion of innovation. This paper describes the findings of case study research in which 16 ASISTM projects were selected as innovation exemplars. A definition of innovation and an innovation framework were developed, through which the case studies were analysed to make sense of the significance of the ideas and practices, participating actors, and outcomes of the projects. Through this analysis we argue that innovation is a powerful idea for framing curriculum development in the sciences at the local level that is generative for students and teachers, and that these ASISTM projects provide valuable models for engaging students, and for teacher professional learning.

This essay focuses on the National Mapping of Teacher Professional Learning (2008), a report that we co-authored along with a number of other researchers on the basis of extensive surveys and interviews relating to the policies and practices of teacher professional learning in Australia. The report is an update of an earlier survey conducted by David McRae and others, entitled PD 2000, and it registers significant changes in attitudes and practices relating to professional learning across Australia in the intervening period. Perhaps the most significant development is the way professional learning is now recognized as an important vehicle for education reform by systems, schools and by teachers themselves, most notably the standards-based reforms that have such a decisive effect on the policy landscape here in Australia and in other countries. The work of the AATE in developing the Standards for Teachers of English Language and Literacy (STELLA) is mentioned in the report. It was acknowledged that STELLA provides a generative framework for professional learning, sometimes in contradiction to more managerial approaches. The question remains, however, of how English teachers as a professional community might locate themselves within the policy landscape described in this report. This essay is an attempt to promote this kind of discussion and to argue the distinctive nature of the standpoint that English teachers might bring to thinking about and planning for professional learning and practitioner inquiry.

The sperm cells of Rhododendron laetum and R. macgregoriae differentiate within the pollen tube about 24 h after germination in vitro. Threedimensional reconstruction shows that the sperm cells are paired together, and both have extensions that link with the tube nucleus, forming a male germ unit. Quantitative analysis shows that the sperm cells in each pair differ significantly in surface area, but not in cell volume nor in numbers of mitochondria or plastids. When isolated from pollen tubes by osmotic shock, the sperm cells became ellipsoidal and surrounded by their own plasma membrane, while a proportion remained in pairs linked by the inner tube plasma membrane. Both generative and sperm cells are visualized in pollen tube preparations by immunofluorescence with anti-tubulin and anti-actin monoclonal antibodies (MAbs) combined with H33258 fluorescence of the nuclei. Video-image processing shows the presence of an axial microtubule cage in the generative cells, and some microtubules are present in the cytoplasmic extensions that clasp the tube nucleus. Following sperm cell division, the extensive phragmoplast between the sperm nuclei is partitioned by the plasma membranes.

Proplastids of both tapetal cells and microsporocytes were present early in anther development. Tapetal proplastids differentiated—probably into elaioplasts—at late microspore stage. The tapetal cytoplasm was completely resorbed by early tricellular pollen stage. Microspore proplastids differentiated into amyloplasts at early bicellular stage, and were present in both vegetative and generative cells. In the generative cell, the amyloplasts were ephemeral and apparently degenerated within autophagic vacuoles. Plastids were absent from sperm cells. Vegetative cell amyloplasts increased in number apparently by fission such that one amyloplast produced one amyloplast and one proplastid per division. Mature pollen grains were estimated to contain between 550 and 820 amyloplasts with only one starch granule per plastid.

Young people today increasingly cause adults anxiety. This anxiety translates into a raft of interventions and strategies and programs that target young people. These imaginings reflect and constitute a range of anxieties about the dangers posed by some young people, or to some young people, and how these risks might be economically and prudently managed. These processes can have a range of often negative consequences (intended or otherwise) for individuals and populations of young people. I argue that Foucault's work on disciplinary, sovereign and governmental forms of power provides a generative framework for analysing why growing up is often seen to be a risky business for contemporary populations of young people.
