Infectious Disease Ontology

Technological developments have resulted in tremendous increases in the volume and diversity of the data and information that must be processed in the course of biomedical and clinical research and practice. Researchers are at the same time under ever greater pressure to share data and to take steps to ensure that data resources are interoperable. The use of ontologies to annotate data has proven successful in supporting these goals and in providing new possibilities for the automated processing of data and information. In this chapter, we describe different types of vocabulary resources and emphasize those features of formal ontologies that make them most useful for computational applications. We describe current uses of ontologies and discuss future goals for ontology-based computing, focusing on its use in the field of infectious diseases. We review the largest and most widely used vocabulary resources relevant to the study of infectious diseases and conclude with a description of the Infectious Disease Ontology (IDO) suite of interoperable ontology modules that together cover the entire infectious disease domain

Including visual representations within senior high school biology assessment : Considerations of grammatical complexity

This paper analyses the opportunities for presenting knowledge that are created when assessment allows senior high school biology students to draw on linguistic and visual resources when constructing meaning in response to short-answer examination-style questions requiring a sequential explanation. Students within one senior high school biology class were given the opportunity to respond to an examination-style question through both written and visual representations. Analysis of the student responses for high and middle-achieving students, from a systemic functional linguistics perspective, indicates that high-achieving students use a broader range of grammatical forms more often than middle-achieving students to present key understandings of classification and composition within both written and visual representations. Including opportunities within assessment for students to express knowledge through written and visual representations allows for students to elaborate within their short-answer responses and to construct the broader range of representations that is valued within the discipline, but explicit guidance is required to support all students to make use of the complex grammatical patterns within written and visual representation. For senior high school biology students to be successful in the final stages of schooling, explicitness about the complex grammars of visual and written representations is required within curriculum and pedagogy

Supporting undergraduate students’ acquisition of academic argumentation strategies through computer conferencing

Executive Summary Background This research grows out of work on the importance of argumentation in developingstudents’ critical abilities. It focuses attention on how students argue in computer mediated conferences as opposed to traditionalwritten assignments, investigating the way in which argumentation is realised within the relatively new context of computer conferencing which allows extended written discussions to take place overa period of weeks. Such text-based asynchronous conferencing is typically characterised by features of both spoken and written modes. Aims The main aims of the project were: • to investigate the argumentation strategies used in asynchronous text-based computer conferences; • to compare the argumentation strategies developed through conferencing with those used in the writing of academic assignments; • to examine the strategies used by tutors to encourage and facilitate argumentation in text-based computer conferences. Methods Data was collected over two years for the distance undergraduate course ‘Perspectives on Complementary and Alternative Medicine’ at the Open University.Qualitative data was obtained through interviews with the course chair, tutors and students, and through a student questionnaire. Assignments and computer-mediated tutorials were collected for textual analysis, although the timing of the assignments meant that analysis has only just begun on the essay data. To analyse the argumentation in the computer conferences and assignments a method of categorising, coding and tracking argumentative discourse was developed building on earlier work by the authors. In addition, computational searches were carried out to compare linguistic features across conference and assignment data. Results In tutorial conferences, student discussion tended to take the form of collaborative co-construction of an argument through exchanging information and experience to substantiate a position. However, students were also prepared to challenge other viewpoints. In both cases, they frequently drew on personal and professional experience to support argument claims. The use of these strategies suggests that text-based conferencing lends itself to the collective combining of diverse sources of information, experiences and ideas. Conference discussions were often personalised with fewer explicit logical links marking argument structure. They were also marked by complexity of argument strands, many of which reached no conclusion. Preliminary analysis of argumentation in assignments suggests that this did not, however, adversely affect students’ ability to create a more traditional, linear argument in their essays. Further analysis will be undertaken to compare argumentation strategies across the two sets of data. Tutors expressed concern about levels of participation in the tutorial conferences, which varied quite considerably. They also felt uncertain about their own knowledge of appropriate pedagogic strategies which would encourage students to participate in a collaborative yet critical way, and tended to rely on strategies from face-to-face teaching. Analysis of the conference discussion showed that tutors made fewer claims than students and were also less likely to provide information in support of their claims. There was, therefore, little modelling by tutors of the basic type of argumentation that would be expected in formal written assignments.Despite these concerns, student responses indicated that having a tutor and a group of peers to interact with, or just to observe, was valued as a supportive feature of this form of distance learning. No clear picture arose of how to make conferencing more interactive for more students, and this reinforces the sense gained from the tutor interviews of the difficulty of proposing a model of tutoring in computer conferences that will necessarily engage all students or raise the level of discussion and debate. Conclusions Our study suggests that text-based conferencing has an important role to play in developing students’ argumentation strategies and understanding of academic discourse and conventions. In view of its hybrid nature, somewhere between spontaneous speech and formal academic writing, course designers and tutors should aim to take advantage of both aspects – on the one hand, the informal dialogic exchange of opinions and co-construction of knowledge, and on the other,the opportunity for consolidation, reflection and re-positioning. Our findings reinforce the view that students’ willingness to exchange ideas freely and openly is partly a consequence of how personally engaged, at ease and confident students feel with one another and their tutor. In particular, it seems that there is a role for the interpersonal and, to some extent, the chat and the frivolity, which in some other studies discussed in the literature review have been regarded as negative influences. Recommendations To facilitate students’ development of argumentation and learning more generally,tutors need greater awareness of the ways in which academic argumentation operates in computer conferencing as compared to written assignments. Since pedagogic strategies developed in other contexts may not transfer well to computer conferencing, there is a need for targeted professional development, focussing in particular on: • Choosing topics for discussion and designing effective task prompts; • Supporting weaker students; • Encouraging challenging of ideas; • Finding the right tone to facilitate peer discussions. Some specific suggestions are made within the report, but our recommendations at this stage remain tentative as we still have to complete the analysis of the assignment data and draw conclusions about the impact of the computer conferencing on the quality of written argumentation within this more formal context

Re-thinking context and reflexive mediation in the teaching of writing

This paper calls for a renewed focus on the teaching of writing. It proposes a conceptual model, based on a social realist perspective, which takes account of the ways in which teachers reflexively mediate personal, professional and political considerations in enacting their writing pedagogies. This model extends understanding of the factors contextualising the teaching of writing. It also provides a useful guide for research into the teaching of writing and a prompt for reflexivity in professional development

What is English now? The construction of subject English in contemporary textbooks for Australian secondary schools

Australian educators are currently engaged in widening debates about the performance of the nation’s schools, teachers and students. Perceived literacy deficits among secondary students have fuelled the debate, and this has precipitated reforms to English curricula at both National and State levels. The newly revised curricula attempt to improve student achievement through more systematic teaching about the English language and language skills. In response to the changes, major education publishers in Australia have released revised textbooks for English that purport to engage with the new curriculum. This research study considered whether such new resources offer genuinely fresh and effective approaches to English, or whether they reproduce established conceptions and methods in new packaging. Guided by Michel Foucault’s concepts of social technology and discursive practice, and Ian Hunter’s detailed historical-theoretical analysis of English, this inquiry used a combination of content analysis and theorisation to identify the models of English embodied in textbooks. Five recent publications were studied to expose both the content and the underlying ideas and pedagogical assumptions about English contained within. Hunter’s historical matrix was applied to categorise the content and quantify the overall proportions of rhetorical, ethical and aesthetical instruction evident in the resources. The findings were interpreted according to Hunter’s genealogy of English and its prevailing discourses, in an effort to offer some clarification about the assumptions that shape school English, and its direction now and in the future. The findings suggest that despite attempts to reconstruct English around the teaching of language skills, established conceptions of English have resurfaced, pulling the subject back toward the ethical domain and distorting the overall balance of content. While the data appears to reflect an apparent prominence of rhetorical skilling, analysis of the content demonstrates how this initiative is obscured by a superficial and mechanical treatment of language and a subsequent preoccupation with the ethical. The oscillation between rhetoric and ethics further reveals a visible circumvention of aesthetics, which is unvaryingly the most neglected category. The thesis concludes that change in English is likely being impeded by teaching materials, conceptual frameworks and assumptions that continue to frame English as a primarily ethical activity, in which linguistic skilling is subordinated to self-formation

Critical Examinations of the Known and the Unknown in Social Science: Where Do We Go from Here?

If the use of social science assumptions and beliefs is what helped set fields of professional practice on the quest for recognition in the academy, what does the recent outpouring of publications on the limits of science reveal about sociocultural research prospects at the dawn of the 21st century? The last few years alone have witnessed the publication of special journal issues on the scientific wars of the nineties, year long professional association debates on the known and unknown, and new books and online data sources proclaiming the end of social science. Cumulatively, research and commentary on the limits of science offer pessimistic and optimistic arguments about advances in understanding intractable sociocultural problems that center on understanding extraordinary complexity. We come down on the optimistic side, encouraged by possibilities for using heuristic tools to identify propositions and ideologies presented across a variety of interpretive texts written to accomplish the function of expressing interpretations on the known and unknown in sociocultural research

ISO and Social Standardisation: Uncomfortable compromises in Global Policy-Making

This paper intends to explore the involvement of ISO, the world’s most iconic standard-setting institution, in the field of social responsibility, leading to the publication of the ISO26000 standard in November, 2010. Through several aspects of this experience, an almost decade-long process, I will show how ISO developed a new political structure aimed specifically at creating global policy, originating one the most sophisticated frameworks in existence to consensualise "universal" sociopolitical principles and infuse them with the legitimacy of a "global" technocracy and liberal institutions. Moreover, I will use the latest ISO26000 experience to argue that conceptual and institutional minimalism, which favours "soft" approaches towards global policy-making, paradoxically results from combining a technocratic aim for global compatibility with more participatory decision-making arrangements involving previously excluded socio-political actors. In that sense, ISO’s upgraded participatory mechanisms solved certain deadlocks suffered by previous initiatives only to affront and spark a new round of contradictions and consequences. Thus, I will conclude commenting on the intrinsic relationship between global standards, governance and complexity, and the difficulties of politically articulating programmes with dissimilar functional differentiation
