From Entertainment to education: can social software engage the reticent writer?
No full textAcademic writing is traditionally associated with the individual practice of ‘crafting’ the essay, which for some students is often a daunting and lonely task (Catt and Gregory, 2006). This is in stark contrast to the enthusiastic generation of collaborative content within Web 2.0 environments, as “social networking sites not only attract people but also hold their attention, impel them to contribute, and bring them back time and again” (The New Media Consortium and the Educause Learning Initiative, 2007. p.12). The value of collaborative writing has been recognised (Christensen and Atweh, 1998; Storch, 2005); however, the question arises as to whether students can and are motivated to make the transition from writing for social networking to writing for social learning. The challenge for Higher Education is realising the potential and ‘bridging the gap.’
In a bid to harness this creativity, energy and sociability, we have been exploring open source technologies and how they might enhance collaborative research, writing and learning amongst a range of student groups (pre-degree, first year undergraduates and postgraduates). This presentation will introduce practical case studies of these initiatives and their initial evaluation, illustrating how these tools (PBwiki and Ning) are being used to foster learning communities and encourage regular writing practice within a formative, collaborative environment
Mathematics through/for understanding social life:\ud productive pedagogies meets critical mathematics
No full textThis paper discusses how the involvement of young people in "real" research activities can be an effective pedagogy for learning for mathematics as well other life skills. However, such collaboration with young people presents dilemmas to their teachers. The concepts of productive pedagogy developed by one school reform movement in Australia are used to reflect on the SARUA project that works for students from underrepresented backgrounds in higher education
Strategies for comparing decimal numbers with the same whole-number part
No full textThe strategies employed by 130 Grade 5 Brisbane students in comparing decimal numbers which have the same whole-number part were compared with those identified in similar studies conducted in the USA, France and Israel. Three new strategies were identified. Similar to USA results, the most common comparison errors stemmed from the incorrect whole-number strategy in which length is confused with size. The findings of this present study tend to support Resnick et al.’s (1989) hypothesis that the introduction of decimal-fraction recording before common-fraction recording seems to promote better comparison of decimal numbers

Histone deacetylase inhibitors and hemoglobin F induction in beta-thalassemia
No full textEpigenomic modifiers, such as histone deacetylase inhibitors, are compounds that regulate gene expression by interfering with the enzymatic machinery that maintains the proper chromatin structure of the nucleus. These compounds are at the forefront of novel therapeutic agents for the treatment of several diseases including cancer and genetic disorders such as beta-thalassemia and sickle cell disease. Here we review the current understanding of the mechanism of action of epigenomic modifiers in the treatment of beta-thalassemia and sickle cell anemia. We also discuss how the lessons learned from the study of the effects of these compounds on the P-globin locus, one of the best characterized regions of the human genome, might contribute to the understanding of the mechanism of action of these same compounds in cancer, where the specific regions of the genome that are responsible for the pathophysiology of the disease are often poorly defined.

Conceptions tensions in globalization and its effects by\ud mathematics educators
No full textThe effects of the increasing international academic contacts and the globalisations of\ud
research and curriculum in mathematics education are wide spread and their impacts are\ud
experienced differently in many countries around the world. This paper reports on data from three focus groups conducted with mathematics educators from universities in Australia and New Zealand, The Philippines and Colombia. It discusses some tensions raised by these academics in coming to grips with the globalisation of their discipline
A patient with headache, right upper extremity and right hemithorax hypothermalgesia
No full textWe present a case of partial Wallenberg syndrome also called partial lateral medullary syndrome, a hemorrhagic or ischemic stroke of the area fed by the posterior inferior cerebellar artery and the clinical manifestation depends on the extension of the lesion : dorsal-ventral, medial-lateral and rostrocaudal. Five types have been described. Our patient had headache, hoarseness, right upper extremity, right hemithorax and right upper gluteal hypothermalgesia implicating the involvement of the cervical, the thoracic and part of lumbar fibers of the left lateral spinothalamic tract and the ambiguous nucleus ; an entity not described before. The imaging done to our patient disclosed the dissection of the left vertebral artery. He was treated with anticoagulation with gradual improvement in his symptoms
Moyamoya syndrome with intraventricular hemorrhage in an adult with factor V Leiden mutation
No full textObjective: To report a case of proximal occlusion of 2 major cerebral vessels associated with moyamoya network circulation that manifested by spontaneous intraventricular hemorrhage. Design: Case report. Patient and Results: A 36-year-old Syrian man presented with symptoms of sudden-onset headache, neck stiffness, and confusion. The computed tomography scan of his brain showed intraventricular bleeding, and the subsequent 4 vessel angiographies revealed occlusion of the left middle and anterior cerebral arteries with moyamoya appearance in the terminal branches. The coagulation profile showed the presence of heterozygous factor V Leiden mutation. The patient was treated conservatively until resolution of his blood clot, and later he was started on oral anticoagulation. Conclusion: Factor V Leiden mutation may cause large cerebral vessel occlusion with moyamoya syndrome in adults. ©2005 American Medical Association.

Higher-intellectual functioning, empowerment and oral communication in mathematics instruction
No full textDescribes two studies which are both examples of communication and its effect on mathematics teaching. The first looks at language as mediating in peer relations as students work in small groups on problem solving activities. The second study looks at how teachers in their classroom communication define the nature of mathematics and how students are to engage in it
