The Australian Early Years Learning Framework: learning what?

Early childhood education and care have assumed importance in many government policy agendas. This attention is often accompanied by calls for greater accountability regarding the anticipated learning outcomes for young children. In Australia, the expected learning outcomes for children aged birth to five years are outlined in the recently published Early Years Learning Framework (EYLF). In this article, the author examines the relationship between the EYLF’s outcomes and subject area or content knowledge. The article draws from post-structural and social constructionist understandings of knowledge as unfinished, contestable and contextual. The author concludes that it is not content knowledge itself that is problematic, but it is the way the child and teacher are often positioned in relation to that knowledge that constrains the potential for effective teaching and learning in the early years. The author suggests that revisiting traditional assumptions about content knowledge extends and develops many of the ideas about teaching and learning that are identified in the EYLF, and opens up new identity positions for both children and early childhood educators

A multi-targeted approach to suppress tumor-promoting inflammation

Cancers harbor significant genetic heterogeneity and patterns of relapse following many therapies are due to evolved resistance to treatment. While efforts have been made to combine targeted therapies, significant levels of toxicity have stymied efforts to effectively treat cancer with multi-drug combinations using currently approved therapeutics. We discuss the relationship between tumor-promoting inflammation and cancer as part of a larger effort to develop a broad-spectrum therapeutic approach aimed at a wide range of targets to address this heterogeneity. Specifically, macrophage migration inhibitory factor, cyclooxygenase-2, transcription factor nuclear factor-κB, tumor necrosis factor alpha, inducible nitric oxide synthase, protein kinase B, and CXC chemokines are reviewed as important antiinflammatory targets while curcumin, resveratrol, epigallocatechin gallate, genistein, lycopene, and anthocyanins are reviewed as low-cost, low toxicity means by which these targets might all be reached simultaneously. Future translational work will need to assess the resulting synergies of rationally designed antiinflammatory mixtures (employing low-toxicity constituents), and then combine this with similar approaches targeting the most important pathways across the range of cancer hallmark phenotypes

The historical ecology of Pacific herring: : Tracing Alaska Native use of a forage fish

Long-term use of herring by Alaska Natives is not well-documented over space or through time, yet this information can illuminate pre-industrial patterns of herring abundance and distribution. Such information is important to understand the sustained relationships Alaska Native fishers and egg collectors have had with herring. Understanding the genetics of pre-industrial herring may also inform management of the fish and fisheries to insure their survival into the future. In this paper, we attempt a contextualized account of the long-term history of Alaska Native herring fisheries, bringing together archaeological, ethnographic, and ethnohistorical data. We tie these together as background for presenting the preliminary results of the NSF-funded project, The Archaeology of Herring: Reconstructing the Past to Redeem the Future (No. 1203868). We have now tested 84 herring bone samples from 17 archaeological sites in Alaska expanding beyond Speller et al. (2012), having tripled the earlier archaeological dataset. The oldest herring bones identified archaeologically in Alaska are dated to more than 10,000 cal BP. Early Holocene and Middle Holocene sites have also yielded herring bones, although most of the record dates to the last 2400 years. Preservation of genetic information is effectively complete for the last 2400 years, but achievable back to the terminal Pleistocene (68% success rate for samples between 10,500 and 2400 cal BP). This gives considerable confidence to the potential to expand the analyses and develop a richer pattern of biological variability. The resulting data show genetic continuity between archaeological and modern herring populations. The main technical challenge for the future is to extract adequate amounts of nuclear DNA from the ancient samples for identifying more informative DNA markers that can be used to more effectively reveal any population diversity and/or population size changes over time when compared to modern herring

Integrating Values, Purposes, and Visions for Responsible Development

This chapter highlights a study showing that knowledge sharing and envisioning processes can have positive effects on human and social capital growth within a network. The chapter begins by arguing that a responsible development perspective can be more proactive approach than a sustainability perspective. Some actors (non-profit, public, and private) have achieved responsible development goals by integrating values, purposes and visions. More specifically, we conducted a study testing a methodology that can guide a process of building a strategic vision within a network with the goal of improving their responsible development orientation. The chosen methodology is “Participatory Action Research”. The implementation of the envisioning process was studied via quantitative/qualitative research tools. The methodology was tested in an official cross-country project funded by the European Commission. The project was selected as a best practice by the same European Union Commission. The study highlights the importance of envisioning processes in building social and human capital at the inter-organizational level and, in particular, in highly complex sectors such as those oriented towards improving social responsibility. In fact, work on the envisioning process itself represents an essential instrument for developing strategic objectives to be shared among actors within networks that intend to promote responsible development and improve their human and social capital. This bottom-up process of envisioning can also facilitate cultural interaction among community members, even in a cross-country context. This relevant “learning-by-interacting” experience, can create a growth process for the human and social capital of entire communities. The creation of social capital also promotes the development of shared knowledge and advances leading to the general understanding of common core objectives and appropriate ways of acting within the social system. The chapter ends with recommendations for future research

Autoantibodies against matrix metalloproteinase-1 in patients with localized scleroderma

Background: Localized scleroderma (LSc) is characterized by cutaneous fibrosis and various autoantibodies. Objective: To determine the presence or levels of antibodies (Abs) against matrix metalloproteinase (MMP)-1 and their clinical relevance in LSc. Methods: Anti-MMP-1 Ab was examined by ELISA (Enzyme-Linked ImmunoSorbent Assay) and immunoblotting using human recombinant MMP-1. MMP-1 collagenase activity was determined using biotinylated collagen as substrate and the amount of cleaved biotinylated fragments of collagen by MMP-1 was measured by ELISA. Results: LSc patients exhibited significantly elevated IgG anti-MMP-1 Ab levels relative to normal controls at similar level of patients with systemic sclerosis (SSc). However, IgG anti-MMP-1 Ab levels were comparable among the 3 LSc subgroups: morphea, linear scleroderma, and generalized morphea. When absorbance values higher than the mean + 2S.D. of normal controls were considered positive, IgG or IgM anti-MMP-1 Ab was found in 46% and 49% of total LSc patients and SSc patients, respectively. Anti-MMP-1 Ab was detected most frequently in morphea patients (60%), followed by linear scleroderma patients (47%) and then generalized morphea patients (25%). LSc patients positive for IgG anti-MMP-1 Ab had elevated levels of IgG anti-single-stranded DNA Ab, IgG anti-nucleosome Ab, and shorter disease duration relative to those negative. The presence of anti-MMP-1 Ab in LSc patients was confirmed by immunoblotting. IgG isolated from LSc patients\u27 sera positive for IgG anti-MMP-1 Ab by ELISA inhibited MMP-1 collagenase activity. Conclusion: These results suggest that anti-MMP-1 autoantibody is a novel autoantibody in LSc. c 2008 Japanese Society for Investigative Dermatology

'I know it's bad for me and yet I do it': exploring the factors that perpetuate smoking in Aboriginal Health Workers - a qualitative study

The electronic version of this article is the complete one and can be found online at: http://www.biomedcentral.com/1472-6963/12/102BACKGROUND Aboriginal Health Workers (AHWs) have a mandate to deliver smoking cessation support to Aboriginal people. However, a high proportion of AHWs are smokers and this undermines their delivery of smoking cessation programs. Smoking tobacco is the leading contributor to the burden of disease in Aboriginal Australians and must be prevented. Little is known about how to enable AHWs to quit smoking. An understanding of the factors that perpetuate smoking in AHWs is needed to inform the development of culturally relevant programs that enable AHWs to quit smoking. A reduction of smoking in AHWs is important to promote their health and also optimise the delivery of smoking cessation support to Aboriginal clients. METHODS We conducted a fundamental qualitative description study that was nested within a larger mixed method participatory research project. The individual and contextual factors that directly or indirectly promote (i.e. perpetuate) smoking behaviours in AHWs were explored in 34 interviews and 3 focus groups. AHWs, other health service staff and tobacco control personnel shared their perspectives. Data analysis was performed using a qualitative content analysis approach with collective member checking by AHW representatives. RESULTS AHWs were highly stressed, burdened by their responsibilities, felt powerless and undervalued, and used smoking to cope with and support a sense of social connectedness in their lives. Factors directly and indirectly associated with smoking were reported at six levels of behavioural influence: personal factors (e.g. stress, nicotine addiction), family (e.g. breakdown of family dynamics, grief and loss), interpersonal processes (e.g. socialisation and connection, domestic disputes), the health service (e.g. job insecurity and financial insecurity, demanding work), the community (e.g. racism, social disadvantage) and policy (e.g. short term and insecure funding). CONCLUSIONS An extensive array of factors perpetuated smoking in AHWs. The multitude of personal, social and environmental stressors faced by AHWs and the accepted use of communal smoking to facilitate socialisation and connection were primary drivers of smoking in AHWs in addition to nicotine dependence. Culturally sensitive multidimensional smoking cessation programs that address these factors and can be tailored to local needs are indicated.Anna P Dawson, Margaret Cargo, Harold Stewart, Alwin Chong and Mark Danie

Comparative effectiveness of approved first-line anti-angiogenic and molecularly targeted therapeutic agents in the treatment of good and intermediate risk metastatic clear cell renal cell carcinoma

BACKGROUND: Based on improved clinical outcomes in randomized controlled clinical trials (RCTs) the FDA and EMA have approved bevacizumab with interferon, sunitinib, and pazopanib in the first-line treatment of low to intermediate risk metastatic clear cell renal cell carcinoma (mRCC). However, there is little comparative data to help in choosing the most effective drug among these agents. METHODS: We performed an indirect comparative effectiveness analysis of the pivotal RCTs of bevacizumab with interferon, sunitinib, or pazopanib compared to one another or interferon alone in first-line treatment of metastatic or advanced RCC. Endpoints of interest were overall survival (OS), progression free survival (PFS), and response rate (RR). Adverse events were also examined. RESULTS: The meta-estimate of the hazard ratio (95% confidence interval) for OS for bevacizumab with interferon vs. interferon alone was 0.86 (0.76-0.97), for sunitinib vs. interferon alone was 0.82 (0.67-1.00), for pazopanib vs. interferon alone was 0.74 (0.57-0.97), for sunitinib vs. bevacizumab with interferon was 0.95 (0.75-1.20), for pazopanib vs. bevacizumab with interferon was 0.86 (0.64-1.16), and for pazopanib vs. sunitinib was 0.91 (0.76-1.08). Similarly, bevacizumab with interferon, sunitinib, or pazopanib had better PFS and RR than interferon alone. Sunitinib and pazopanib had better RR than bevacizumab with interferon and there was suggestive evidence pazopanib may outperform sunitinib in terms of RR. CONCLUSIONS: Bevacizumab with interferon, sunitinib, and pazopanib are adequate first-line options in treatment of mRCC. Interferon alone should not be considered an optimal first-line treatment.
