What is the position/contribution of biology in environmental education

In this paper I intend to argue that biological science education and environmental education have traditionally represented fundamentally different discourses - that they have explicitly or implicitly adopted different epistemologies and ontologies - and that this difference has had implications for the conduct of research in these fields. I will draw on recent developments in theory, policy and practice in the field of environmental education to argue that this field tends to be located within a social discourse - that there is a foundation in policy and practice for considering environmental issues as fundamentally social and ethical in nature, rather than in some sense objectively existing. I then consider a rising topic in biology education (that of Biotechnology) as one which while tending to be treated within a scientific discourse, would be more fully explored educationally within a social discourse. I conclude by suggesting that in biology education research we need to consider a reconciliation of these historically differing perspectives.

Marketing position taxonomies : an empirical analysis

Despite the continuing need for an empirically validated classification of marketing positions, for theoretical and practical purposes, it appears that no such schema exists. This study contributes to the development of such a taxonomy through an empirical examination of marketing positions. Specifically, the research extends an existing taxonomy by empirically investigating personal selling marketing activities. Based on the taxonomy developed by Darmon (1998), data were collected about the information load, information complexity, and time and relationship management activities of marketers. Various analytical techniques were used to investigate specific features of the instrument and the taxonomy, as well as to provide convergence for the conclusions drawn by the researchers. It was established that sales positions can be more meaningfully identified, and, therefore, better categorised, by six dimensions than by job title or job role. Further, it appears that marketers in the same selling position vary significantly on these dimensions. These findings have important implications for marketing theory, applied research and management. However, future research should refine the instrument used in this study, since some anomalies emerged in the findings, and extend the study by investigating a wider range of marketing positions. Such research may also explore whether the dimensions identified in this study influence the performance and job satisfaction of marketers, and the extent to which marketing managers account for these variations.

There's no place like home : unhomely moments in three postcolonial picture books

One of the principal strands of postcolonial theory and critical practice is the interrogation of received versions of colonial history. This paper investigates the extent to which three contemporary picture books, Gavin Bishop's The House that Jack Built, John Marsden and Shaun Tan's The Rabbits, and Thomas King and William Kent Monkman's A Coyote Columbus Story, mobilise postcolonial strategies in their representations of place. In particular, it focuses on how postcolonial textuality unsettles and transgresses notions of "homeliness" in narratives involving the displacement of colonised and colonising peoples. As the shifting power relations of colonialism render unhomely what has previously been homely (especially for colonised peoples), so they involve a contrary move in which unhomely spaces are changed into simulacra of lost or abandoned homes. Drawing upon Walter Benjamin's formulation of materialist historiography, Homi Bhabha describes what he terms 'the unhomely moment' as that in which personal and psychic histories intersect with the violent dislocations of colonialism. This paper will argue that such unhomely moments shape the visual and verbal narratives of The House that Jack Built, The Rabbits and A Coyote Columbus Story, all of which deal with the trauma which occurs when cultures previously geographically and psychically distant are brought into close contact with each other. Written to and for children who are citizens of postcolonial cultures, these texts disclose the unease which persists in contemporary societies where colonial histories are rehearsed and revisioned. However, the paper will argue that the three texts position readers in quite different ways; for instance, while the verbal text of The Rabbits constructs an implied author capable of speaking for the colonised and offering readers a very circumscribed subject position, Thomas King's narrative in A Coyote Columbus Story engages in a dialogic playfulness which allows readers to adopt a variety of reading positions. For each text, some key representations of unhomely moments will be considered, and the paper will explore the extent to which they construct forms of temporality which negotiate the space between history and its significances within crosscultural and intercultural formations.

Redefining teacher education through a `multiple space` model: examining the forgotten spaces that teachers work in

This paper maps the current debates surrounding school-based and university-based teacher education models, and presents a ‘multiple-space’ model of teacher education that both explores and values the many ‘forgotten’ spaces that teachers work in. It draws from a variety of research studies, including my own doctoral work, to argue for a new approach to teacher education programs. I suggest that in order for teacher education to move beyond separatist, binary models, we need to adopt a ‘multiple-space’ view of learning to be a teacher that embraces the notion that teachers do not learn about theory in a university space, nor do they simply work in a classroom space.

On the effect of path loss rates on the optimal receiver position in sensor networks

In this paper we examine the problem of finding an optimal position for a receiver node in a single-hop sensor network. The basic idea is to minimize the network energy consumption according to a particular network cost function. Our contribution is to simply show the effect of signal path loss rates and sensor weighting on the optimal receiver position.

Bourdieu`s reflexive sociology and `spaces of points of view`: whose reflexivity, which perspective?

This paper considers Bourdieu's concepts of perspectivism and reflexivity, looking particularly at how he develops arguments about these in his recent work, The Weight of the World (1999) and Pascalian Meditations (2000b). We explicate Bourdieu's distinctive purposes and deployment of these terms and approaches, and discuss how this compares with related methodological and theoretical approaches currently found in social and feminist theory. We begin by considering three main ways in which 'reflexivity' is deployed in current sociological writing, distinguishing between reflexive sociology and a sociology of reflexivity. This is followed by a discussion of the main aspects of Bourdieu's approach to 'reflexive sociology' and its relation to his concepts of social field, perspectivism and spaces of point of view. He argues that we need to interrogate the idea of a single 'perspective' and account especially for the particularity and influence of the 'scholastic' point of view. He characterizes this latter point of view as unaware of its own historicity and as largely concerned with contemplation and with treating ideas primarily as abstractions (Bourdieu, 2000b). Bourdieu's intervention is to argue, as he has throughout his work, for a more reflexive account of one's location and habitus, and for sustained engagement with ideas and social issues as practical problems. Bourdieu exhorts researchers to work with 'multiple perspectives' (Bourdieu et al., 1999, p. 3), the various competing 'spaces of points of view', without collapsing into subjectivism or relativism. We then consider recent feminist engagements with and critiques of Bourdieu's notion of reflexivity and chart some of the main points of contention regarding its relevance and conceptual potential for theorizing gender identities and transformations in current times. We conclude with a brief outline of how we are working with a reflexive sociological approach in a cross-generational study of young women in difficult circumstances, 'on the margins' of education and work.

Organization, decoration

While organizational decoration has been of interest to those who study organizational artefacts, we suggest four ways in which decoration is worthy of fuller attention in organizational studies. First, decoration, ornament and embellishment are not only what we see, but also what we do as managers, consultants, writers and designers of both physical and project spaces. Second, and drawing on the art/craft debate, we note that decoration occupies contested and even liminal aesthetic position and that ‘decorative art’ lies betwixt and between fine art and craft. Neither fully accepted nor fully marginalized, decoration is ‘only applied’ and embodies shifting tensions between form and function. Third, we review the particular negotiations of these tensions at the Bauhaus, a controversial and highly influential aesthetic organization in early 20th century Germany. Fourth, we suggest that decoration, like disorganization, provides a source of complication for organizational studies that are neither pure nor parsimonious.

Adolescent home food environments and socioeconomic position

Many adolescents have diets that are less than optimal, particularly adolescents of low socioeconomic position (SEP). The determinants of SEP differences in adolescent dietary intake are poorly understood. This study examined the home food environments of adolescents and specifically investigated whether low SEP adolescents have less supportive home local environments, fewer eating rules and poorer home availability of fruit and vegetables than adolescents of high SEP. A cross-sectional, self-reported survey was administered to 3,264 adolescents in years 7 and 9, from 37 secondary schools in Victoria, Australia. Adolescent perceptions of the home meal environment, eating rules and home food availability were described and compared across SEP, which was measured using maternal education. Maternal education was linked to various aspects of the home meal environment, as well as home food availability, but not to eating rules. Low SEP adolescents were more likely to report that they were always allowed to watch television during meal times, and that unhealthy foods were always or usually available at home. In contrast, high SEP adolescents were more likely to report that vegetables were always served at dinner, that the evening meal was never an unpleasant time and always or usually a time for family connectedness, and that fruit was always or usually available at home. This study highlights aspects of the home food environment that might explain SEP variation in adolescent diets. Feasible ways of increasing home availability of healthy foods, and encouraging home meal environments to be supportive of healthy eating should be explored, particularly in households of low SEP adolescents.

Children's perceptions of the use of public open spaces for active free-play

Activity performed by children in their free-time may have a significant impact on overall physical activity levels, however, very little is known about the influences on children's active free-play. To examine the role and use of public open spaces, 132 children (6-12 years) from a selection of primary schools participated in small focus group interviews. Children reported that their use of public open spaces was influenced by a combination of intrapersonal, social and environmental factors including; the play equipment and facilities at local parks, lack of independent mobility, urban design features, presence of friends, and personal motivation.

Policing in the 'communal spaces' of major event venues

The recent re-conceptualization of 'mass private property' as one form of 'communal spaces' raises a series of questions concerning policing and security in these domains. This paper applies the concept of 'communal spaces' to an analysis of policing in 'major event venues.' We assess the character of policing in these communal spaces by drawing upon interviews conducted with policing—private and public—personnel operating in major event venues. The paper identifies different perspectives on the nature of policing in these communal spaces and tension between public and private police personnel concerning their respective roles and responsibilities. We conclude by raising issues concerning the implications for the 'public good' in policing at major event venues.

'Particularly happy' arrangement?: Idealism, pragmatism and the enclosed open spaces of Perth garden suburbs

One of the hallmarks of many planned garden suburbs of the early twentieth century is the internal reserve: open space at the rear of residences, without street frontage. An idealistic conception with direct links to overseas planning theory, these spaces were not always well received by either local councils or residents; despite this, many survive today as legacies of early suburban reformism. Perth’s highest-profile planning advocates of the interwar years, most notably town clerk William Bold and the progressive surveying  partnership of Hope and Klem, embraced and encouraged the idea and a number of middle-ring suburbs in Perth feature internal reserves which have survived both encroachment and resubdivision. Some have been given heritage status in recognition of their importance to the history and fabric of particular suburban communities; others remain neglected and essentially unacknowledged. All raise ongoing usage, maintenance and management issues for the councils that have inherited them.
