A doctorate by definition : exploring possibilities and opportunities in education

The author provides a diagram and table which reflect his conceptualisation of issues surrounding the definition of a doctorate. Two broad questions frame this characterisation: (i) what defines the doctorate? and (ii) where to now? In relation to the first question the author contends that the resources available to students, supervisors and institutions significantly influence what is regarded as a 'good' doctorate and the 'protection' of this standard. An overlapping set of issues is identified in response to the question 'where to now'? These are expressed as strategies in negotiating doctorate definitions and futures; some more reminiscent of times past and some cognisant of prevailing conditions, while others offer a qualitatively different strategy that explores (or generates) possibilities and opportunities within the parameters of the doctorate.

Enactive research : transversal possibilities for expanding the imaging of science

This paper explores the notion of the expanded image as a transdisciplinary interaction between people and environments. In support of this proposition, images and imaging will be discussed through a series of transformative steps: from the diagram to the biogram and from the biogram to biotopology. Two research projects, exemplary of a transdisciplinary approach, inform the move to biotopology (the continuous surface of interactions tied to imaging practices): first, theories of enaction in cognitive science foreground co-selective processes and the precariousness of self- organizing systems and supply new ways of imaging body-environment relationships (Stewart et al 2010; Thompson 2007; and Varela et al 1993); and second, the procedural architecture of artist- turned-architects Arakawa and Gins foregrounds the reconfigurability of the co-selective process that becomes an enactive practice. These approaches suggest that if the image were expanded to include the intersection of the human organism’s behaviors, artifacts (such as images) and built- environments, then the ‘person’ whose myriad surfaces flicker towards future action, might become the best description of an expanded form of imaging, always in process and flickering towards future action. The many and non-locatable surfaces of person would defy disciplinary boundaries and interfere with habitual patterns of imaging. Ultimately, the aim of expanding imaging practices is to expand an embodied capacity to configure and reconfigure conceptual and material realms.

Towards methodologically inclusive research syntheses: expanding possibilities

Primary research in education and social sciences is marked by a diversity of methods and perspectives. How can we accommodate and reflect such diversity at the level of synthesizing research? What are the critical methodological decisions in the process of a research synthesis, and how do these decisions open up certain possibilities, while closing down others?

Tablet technologies in early childhood: pedagogical possibilities and limitations

Drawing from recent research literature, this article analyses the paradigmatic and pedagogical shifts occurring in early childhood education due to the emergence of new digital technologies. Over the past decade the role that computers and other digital technologies have played in supporting young children’s learning have been well documented. However, new pedagogical possibilities to support children’s play, learning and inquiries are arising due to tablet technologies (For example, Apple iPads, Kindle or Google Chrome OS). This article has reviewed and analysed recently published research findings in the Australian early childhood context (preschool through to the first year of primary school) considering how tablet technologies are used and understood in this environment. A critical discourse analysis has identified pedagogical possibilities and limitations experienced by teachers, children and their families, when tablet technologies are used as a resource to support children’s play and learning.

Is there an app for that? Looking at possibilities and challenges of digital tools for literacy education

 Portable electronic devices such as the iPad are increasingly taking a place in contemporary childhood experiences including those of schooling (O'Mara & Laidlaw, 2011). As digital media theorists suggest, such new tools invite both "hope and fear" (Gee and Hayes, 2011, p.4), consistent with literacy innovations across history. In both Canada and Australia, educational stakeholders are looking to touch screen devices as having much promise, particularly within literacy education. This paper presentation examines the possibilities as well as the challenges and imagines the future of such digital tools within literacy education, looking at experiences and perspectives in Canada and Australia.
We take a qualitative ecological mode of inquiry approach to our data collection and analysis, drawing on complexity thinking (Davis & Sumara, 2006) to bring our multiple points of view together as diversely positioned educators. Within our individual sites, each author has collected data as a part of longer-term research projects. In this paper presentation we compare and contrast these data sets, attending to significant intersections and juxtaposing issues of culture and globalization. Within this mode of inquiry we value the particularity of the individual contexts, and locate them alongside one another in a larger bricolage (Johnson, 2010).
We examined observational data, documents and artifacts using Freebody and Luke's (1990) four resources model and the further adaptions of this model (see e.g. Luke & Freebody, 1999) to understand how touch screen devices are being used and positioned as literacy tools. We have engaged in collaborative data analysis, often working 'together' using digital tools ourselves to enable collective conversations. For example, we have used Facetime on iPads and laptops, Skype and email to facilitate collective analyses. We applied iterative and recursive analyses to uncover reoccurring themes both within and across sites and artifacts.
As our paper will elaborate, mobile touch screen devices such as iPads are widely being taken up in educational settings, and regarded as having the possibility to shift teaching and learning in new directions, as "paradigm breakers" (p. 4, Gov't of AB, 2011). As personal, mobile devices, these tools present challenges that require educators to think differently about learning and teaching. Our paper also addresses the opportunities and affordances that iPads might offer to learners, as having the potential for students to engage in playful exploration, and in the role of designers, creators, and producers, rather than as passive recipients.

Long-distance endozoochorous dispersal of submerged macrophyte seeds by migratory waterbirds in northern Europe - a critical review of possibilities and limitations

We review whether migratory Anatidae, i.e., swans, geese and ducks, could be acting as vectors for dispersal of Zostera, Ruppia and Potamogeton propagules by endozoochory (carrying seeds in their guts). We list six prerequisites that must all be fulfilled, if successful dispersal should occur. Several Anatidae species feed on these macrophytes, and undertake rapid long-distance movements, making dispersal possible. We identify four problems, which in combination leads us to conclude that long-distance dispersal events are likely to be rare. (i) Most long-distance movements are out of phase with the reproductive efforts of the plants, and if birds arrive at sites when plants still bear seeds, they are likely to depart well after seed stocks have been depleted. (ii) Seed transport by birds will usually be uni-directional, from north to south on autumn migrations. (iii) Most of the gut contents of migratory birds are likely to have been discarded within 300 km of departure. (iv) In many cases, birds will arrive in habitats seriously different from those they departed, i.e., any seeds carried along will have low chances of surviving in their new site. We suggest that northbound dispersal by endozoochory can only occur during spring if waterbirds feed on seeds that have not been depleted and remained frozen down or buried in sediments, or during moult- or post-moult migrations. Moult migration takes place in summer in phase with the reproductive efforts of the plants. Also epizoochorous dispersal (external attachment) is subject to restrictions i, ii and iv.
