Cherbourg State School in historical context.

Cherbourg State School is some 300 kilometres northwest of Brisbane. It is situated in an Aboriginal community at Cherbourg with approximately 250 students, all of whom are Indigenous Australian children. Cherbourg State School aims to generate good academic outcomes for its students from kindergarten to Year 7 and nurture a strong and positive sense of what it means to be Aboriginal in today's society. In a context where the community continues to grapple with many social issues born of the historical processes of dispossession and disempowerment, Cherbourg State School is determined that its children can and will learn to become 'Strong and Smart'. It is a journey that has been charted by Chris Sarra, the school's first Aboriginal principal, in his paper Young and Black and Deadly: Strategies for Improving Outcomes for Indigenous Students, which describes how pride and expectations were engendered in the school over a four-year period from 1998. In this article the author discusses the historical context of the school and its impact on the Indigenous people of Cherbourg. The aim is to consider the historical, political, social and cultural context around the creation of Cherbourg State School. The author critically examines the historical records of the role of the State Government and the white settlers in the setting up and creation of the Aboriginal Reserve and later the primary school. Throughout the author addresses an absence � a voice missing from history � the voice of the Aboriginal people. This exercise in collective memory was designed to provide an opportunity for those who have seldom been given the opportunity to tell their story. Instead of the official view of Cherbourg School it provides a narrative which restores the victims of history to a place of dignity and indeed humanity.

Commentary : Biomaterials offer cancer research the third dimension

In a mini review from 2002, Tyler Jacks and Robert Weinberg commented on the pioneering three-dimensional (3D) culture work from Bissell laboratories and concluded: “Suddenly the study of cancer cells in two dimensions seems quaint if not archaic.” The relevance of this statement for planning and executing mechanistic biological studies and advanced drug testing has been largely disregarded by both academic researchers and the pharmaceutical and biomedical industry in the twenty-first century.

Can tissue engineering concepts advance tumor biology research?

Advances in tissue engineering have traditionally led to the design of scaffold- or matrix-based culture systems that better reflect the biological, physical and biochemical environment of the natural extracellular matrix. Although their clinical applications in regenerative medicine tend to receive most of the attention, it is obvious that other areas of biomedical research could be well served by the powerful tools that have already been developed in tissue engineering. In this article, we review the recent literature to demonstrate how tissue engineering platforms can enhance in vitro and in vivo models of tumorigenesis and thus hold great promise to contribute to future cancer research.

"Has Gothic cake and eats it too : dreaming of Amelia" by Jaclyn Moriarty

Dreaming of Amelia (2009) recounts a small group of HSC students’ final year of high school. Told from multiple perspectives, the novel focuses on shifting senses of self, maturity, and agency as the protagonists move from adolescence to adulthood. The central conflict of the novel results from two ‘bad kids from the bad crowd at bad Brookfield High’ (blurb) transferring to wealthy private school, Ashbury; Amelia and Riley are scholarship students who do not fit with Ashbury’s profile of 'normal student' as it is understood by the school’s students or staff, and their presence in the school community forces many people to reassess their understanding of individual value (or, at least, that’s what the novel claims happens). In the shifting of perceptions, allegiances, and relationships, each of the main characters achieves a stronger sense of their identity, and Dreaming of Amelia is thus firmly located within the tradition of Young Adult (YA) literature, with all its stereotypes of adolescence.

Hungry 24/7? HCI design for sustainable food culture workshop

This workshop proposes to explore new approaches to cultivate and support sustainable food culture in urban environments via human computer interaction design and ubiquitous technologies. Food is a challenging issue in urban contexts: while food consumption decisions are made many times a day, most food interaction for urbanites occurs based on convenience and habitual practices. This situation is contrasting to the fact that food is at the centre of global environment, health, and social issues that are becoming increasingly immanent and imminent. As such, it is timely and crucial to ask: what are feasible, effective, and innovative ways to improve human-food-interaction through human-computer-interaction in order to contribute to environmental, health, and social sustainability in urban environments? This workshop brings together insights across disciplines to discuss this question, and plan and promote individual, local, and global change for sustainable food culture.

EAP essentials : a teacher's guide to principles and practice

Book review - Ancient scholars once journeyed across the Alps to study Italian law while some sailed the Mediterranean to learn Greek philosophy or examine Arabic scripts on science, medicine and mathematics. Devotees of philosophical and religious thought migrated to the Orient in search of transcendental wisdom. Today, the quest for knowledge has not changed as English-medium universities experience unprecedented internationalisation. This book is a publication for such a time as this. The authors invite readers to "join the tribe" (Becher, 1998) and learn the specific academic discourse and culture of English for Academic Purposes (EAP).

The culture of contemporary writers' festivals

This thesis examines the culture of contemporary writers’ festivals in an international context. In the last five decades writers’ festivals have emerged in cities across the world, and during this time they have expanded their literary discussions and debates to include numerous other topics of broad interest to society. To examine the expanded popularity and function of writers’ festivals, this thesis establishes a new vantage point for theorising the content now typically generated by these events using concepts in urban festivals and public culture research. Importantly, the new vantage point addresses the limitations of current commentary on writers’ festivals which routinely claim they trivialize literature, and more generally, contribute to the decline of public culture. The thesis presents two case studies: one on the Brisbane Writers Festival in Australia and the other on the International Festival of Authors in Toronto, Canada. The first case study, which focuses on the 2007 Brisbane Writers Festival, illustrates the many overlapping and often conflicting discourses as well as opinions productively discussed and debated at writers’ festivals. Key topic discussed and debated at the Festival include local topics about the host city—its history, literature and politics, as well as broader literary, political and celebrity culture topics. The diversity of topics discussed at the 2007 Brisbane Writers Festival is typical of the majority of writers’ festivals similarly located outside the largest geographic centres of global literary production and circulation, and designated as ‘peripheral’ festivals in this research. The second case study on Toronto’s International Festival of Authors examines the ways in which the 2006 Festival almost exclusively focussed on literary and celebrity culture discourses, and promoted itself on these terms. The 2006 International Festival of Authors’ discussion and debate of a narrow range of topics is typical of the few writers’ festivals located in global centres of literary production and circulation, and unlike ‘peripheral’ festivals they are not experiencing the same growth in number or popularity. The aim of these ‘international’ Festivals is not to democratise their elite literary beginnings, but rather to promote ‘literature’ as a niche brand for quality writing that is valid on a global scale. This thesis will assert that while all writers’ festivals are influenced by the marketing desires of publishing companies, the aim of international writers’ festivals in marketing to a virtually and globally connected elite literary audience makes them more susceptible to experiencing declines in audience and author participation.

Characterisation of mesenchymal cells from osteophytes in osteoarthritis

Osteophytes form through the process of chondroid metamorphosis of fibrous tissue followed by endochondral ossification. Osteophytes have been found to consist of three different mesenchymal tissue regions including endochondral bone formation within cartilage residues, intra-membranous bone formation within fibrous tissue and bone formation within bone marrow spaces. All these features provide evidence of mesenchymal stem cells (MSC) involvement in osteophyte formation; nevertheless, it remains to be characterised. MSC from numerous mesenchymal tissues have been isolated but bone marrow remains the “ideal” due to the ease of ex vivo expansion and multilineage potential. However, the bone marrow stroma has a relatively low number of MSC, something that necessitates the need for long-term culture and extensive population doublings in order to obtain a sufficient number of cells for therapeutic applications. MSC in vitro have limited proliferative capacity and extensive passaging compromises differentiation potential. To overcome this barrier, tissue derived MSC are of strong interest for extensive study and characterisation, with a focus on their potential application in therapeutic tissue regeneration. To date, no MSC type cell has been isolated from osteophyte tissue, despite this tissue exhibiting all the hallmark features of a regenerative tissue. Therefore, this study aimed to isolate and characterise cells from osteophyte tissues in relation to their phenotype, differentiation potential, immuno-modulatory properties, proliferation, cellular ageing, longevity and chondrogenesis in in vitro defect model in comparison to patient matched bone marrow stromal cells (bMSC). Osteophyte derived cells were isolated from osteophyte tissue samples collected during knee replacement surgery. These cells were characterised by the expression of cell surface antigens, differentiation potential into mesenchymal lineages, growth kinetics and modulation of allo-immune responses. Multipotential stem cells were identified from all osteophyte samples namely osteophyte derived mesenchymal stem cells (oMSC). Extensively expanded cell cultures (passage 4 and 9 respectively) were used to confirm cytogenetic stability and study signs of cellular aging, telomere length and telomerase activity. Cultured cells at passage 4 were used to determine 84 pathway focused stem cell related gene expression profile. Micro mass pellets were cultured in chondrogenic differentiation media for 21 days for phenotypic and chondrogenic related gene expression. Secondly, cell pellets differentiated overnight were placed into articular cartilage defects and cultured for further 21 days in control medium and chondrogenic medium to study chondrogenesis and cell behaviour. The surface antigen expression of oMSC was consistent with that of mesenchymal stem cells, such as lacking the haematopoietic and common leukocyte markers (CD34, CD45) while expressing those related to adhesion (CD29, CD166, CD44) and stem cells (CD90, CD105, CD73). The proliferation capacity of oMSC in culture was superior to that of bMSC, and they readily differentiated into tissues of the mesenchymal lineages. oMSC also demonstrated the ability to suppress allogeneic T-cell proliferation, which was associated with the expression of tryptophan degrading enzyme indoleamine 2,3 dioxygenase (IDO). Cellular aging was more prominent in late passage bMSC than in oMSC. oMSC had longer telomere length in late passages compared with bMSC, although there was no significant difference in telomere lengths in the early passages in either cell type. Telomerase activity was detectable only in early passage oMSC and not in bMSC. In osteophyte tissues telomerase positive cells were found to be located peri vascularly and were Stro-1 positive. Eighty-four pathway-focused genes were investigated and only five genes (APC, CCND2, GJB2, NCAM and BMP2) were differentially expressed between bMSC and oMSC. Chondrogenically induced micro mass pellets of oMSC showed higher staining intensity for proteoglycans, aggrecan and collagen II. Differential expression of chondrogenic related genes showed up regulation of Aggrecan and Sox 9 in oMSC and collagen II in bMSC. The in vitro defect models of oMSC in control medium showed rounded and aggregated cells staining positively for proteoglycan and presence of some extracellular matrix. In contrast, defects with bMSC showed fragmentation and loss of cells, fibroblast-like cell morphology staining positively for proteoglycans. For defects maintained in chondrogenic medium, rounded, aggregated and proteoglycan positive cells were found in both oMSC and bMSC cultures. Extracellular matrix and cellular integration into newly formed matrix was evident only in oMSC defects. For analysis of chondrocyte hypertrophy, strong expression of type X collagen could be noticed in the pellet cultures and transplanted bMSC. In summary, this study demonstrated that osteophyte derived cells had similar properties to mesenchymal stem cells in the expression of antigen phenotype, differential potential and suppression of allo-immune response. Furthermore, when compared to bMSC, oMSC maintained a higher proliferative capacity due to a retained level of telomerase activity in vitro, which may account for the relatively longer telomeres delaying growth arrest by replicative senescence compared with bMSC. oMSC behaviour in defects supported chondrogenesis which implies that cells derived from regenerative tissue can be an alternative source of stem cells and have a potential clinical application for therapeutic stem cell based tissue regeneration.

Sex appeal in advertising : what consumers think

This study examined consumers' attitude toward the use of sexual content in advertisements among there different cultural groups; i.e., individualistic sample (White American), collectivistic sample (US temporal visitors from Asia), and acculturation sample (Asian immigrants). Sixty participants were asked about cultural acceptability of sexual content ads and the favorable attitude toward those ads by using Q-methodology. Asian participants reported less cultural acceptability for sexuality, than either Asian American or North American participants. The findings also revealed that North Americans are more likely to prefer the use of sexual content in advertisement than Asians. Asian-American participants agreed with North American participants in regard to sexually explicit advertising. Implications and limitations were discussed.

A short-term evaluation of a school-based early adolescent injury prevention program

This paper reports on the development of a school-based intervention to reduce risk-taking and associated injuries. There is limited but important evidence that intervention design should ensure participation does not lead to an increase in target risk behaviors with some studies in alcohol and drug prevention finding unexpected negative effects. The short-term evaluation of Skills for Preventing Injury in Youth (SPIY) examined change in interpersonal violence, alcohol and transport-related risks. Intervention (n = 360) and comparison (n = 180) students were surveyed pre/post-intervention. A qualitative analysis based on focus groups (70 students) explored experiences of change. Findings indicate significant positive changes reinforced by students’ reports. A decrease in reported risk-taking for the intervention group and an increase in the comparison group were observed. These findings endorse SPIY as a useful curriculum approach to reducing injuries and lend support to the future conduct of a long-term outcome evaluation.

Mathematical modelling in the early school years

In this article we explore young children's development of mathematical knowledge and reasoning processes as they worked two modelling problems (the Butter Beans Problem and the Airplane Problem). The problems involve authentic situations that need to be interpreted and described in mathematical ways. Both problems include tables of data, together with background information containing specific criteria to be considered in the solution process. Four classes of third-graders (8 years of age) and their teachers participated in the 6-month program, which included preparatory modelling activities along with professional development for the teachers. In discussing our findings we address: (a) Ways in which the children applied their informal, personal knowledge to the problems; (b) How the children interpreted the tables of data, including difficulties they experienced; (c) How the children operated on the data, including aggregating and comparing data, and looking for trends and patterns; (c) How the children developed important mathematical ideas; and (d) Ways in which the children represented their mathematical understandings.
