In this of the International Journal of Critical Indigenous Studies, the articles reveal how competing economies of knowledge, capital and values are operationalised through colonising power within inter-subjective relations. Writing in the Australian context, Greg Blyton demonstrates how tobacco was used by colonists as a means of control and exchange in their relations with Indigenous people. He focuses on the Hunter region of New South Wales, Australia, in the early to mid-nineteenth century to reveal how colonists exchanged tobacco for food, safe passage and Indigenous services. Blyton suggests that these colonial practices enabled tobacco addiction to spread throughout the region, passing from one generation of Indigenous people to another. He asks us to consider the link between the colonial generation of Indigenous tobacco consumption and addiction, and Indigenous mortality rates today whereby twenty percent of deaths are attributed to smoking.

This special edition of the International Journal of Critical Indigenous Studies highlights the work of emerging scholars in the field of Indigenous Studies. The five featured authors were all finalists for the prize awarded by the Native American and Indigenous Studies Association (NAISA) to the best post-graduate student paper at the NAISA meeting held in 2010 in Tucson, Arizona. While the breadth of scholarship encompassed by the term ‘Indigenous Studies’ and the global representation of Indigenous peoples at NAISA mean that the topics and approaches vary widely, a common thematic of fraught post-colonial relations can be discerned within all five articles.

The first two articles of this edition of the journal testify to the lengthening reach of the discipline of Critical Indigenous Studies that is, remarkably, still in its nascence. Emiel Martens examines the development of Maori filmmaking since the 1980s and takes the opportunity to explore this Indigenous cinema in the context of developments in the New Zealand film industry generally. Shifting from cultural production to renewable energy, Steven M. Hoffman and Thibault Martin remind us that in the effort to satiate the demands for energy, it is often Indigenous peoples who bear adverse consequences. Using a social capital framework, the authors examine the impact of the development of hydroelectric power upon a displaced Aboriginal community and conclude that displacement has resulted in an erosion of cohesive social bonds that once ensured a sustainable way of life.

This edition is marked by a strong Antipodean focus. The first three articles bring a critical Indigenous perspective to areas previously cosseted by Western understandings. Robyn Moore, using critical discourse analysis, takes Australian Prime Minister Julia Gillard’s 2011 ‘Closing the Gap’ speech to task for naturalising Indigenous Australia’s position on the wrong side of the social and economic ‘gap’. She argues that, far from accepting white culpability, Gillard instead polishes cultural deficit understandings of Indigenous disadvantage by framing the social and economic divide in meritocratic terms. In so doing, Moore further argues, Gillard casts a benevolent light upon white Australia.

Editorial of "International Journal of Critical Indigenous Studies, Volume 6, Number 1, 2013"

This edition of the International Journal of Critical Indigenous Studies marks the tenth since the journal’s launch in 2008. During that time, over forty articles and eleven book reviews have been published, which is testament to the continuing upward trajectory of Critical Indigenous Studies. Although there continues to be an increasing range of areas of Indigenous research to which a critical focus is brought to bear, a consistent issue for many of the journal’s contributors has been the delineation and application of Indigenous methods and methodologies in social research. The present edition is no exception, with two articles focussing on Indigenous-centred research. The first, by Krystal Summers, reflexively explores the author’s experiences as an undergraduate student undertaking Indigenous-centred research in Peru. As an Indigenous First Nations woman, Summers was mindful that her research practice was faithful to the ethics and protocols outlined in her original project proposal. Her subsequent ‘journey of critical reflexive understanding and storytelling’ supports the proposition of current literature in Indigenous research methodologies that a properly critical Indigenous ethnography will naturally enjoin with Indigenous epistemologies and methodologies.

The International Journal of Critical Indigenous Studies (IJCIS) now complements the recently launched National Indigenous Research and Knowledges Network (NIRAKN) in its efforts to build Indigenous research capacity. In this context the journal provides a platform for the research of Indigenous postgraduates, early- to mid-career researchers, and senior scholars. Indigenous scholars are therefore encouraged to submit their articles to future editions of the IJCIS, an ‘Excellence in Research for Australia’ (ERA) ranked journal.

Editorial of "International Journal of Critical Indigenous Studies, Volume 7, Number 1, 2014"

This edition testifies to the broad international reach of the journal, with contributions variously concerned with Arctic Indigenous communities, the Métis of Canada, Native Hawaiians and Māori of Aotearoa (New Zealand). Two articles stress the need to work collaboratively and respectfully with Indigenous populations whilst conducting research. The first, by Gwen Healey, notes the increased interest in health research in the Arctic, particularly with Inuit populations. Healy seeks to add to the growing body of literature concerned with Indigenous ways of knowing by highlighting Inuit concepts that inform an effective Arctic research model. The second, by primary author Peter Hutchinson and a range of co-contributors, highlights the ways in which Métis collaborators working in health developed a participatory Indigenous research method that was unique in that it foregrounded Métis relationships and relationality. In so doing, the researchers were able to give substance to otherwise staid policy statements about the need for good ethical research conduct.

Editorial of "International Journal of Critical Indigenous Studies, Volume 7, Number 2, 2014"

This edition scales the merlons and embrasures that mark the epistemological barriers that contemporary colonising power continually puts in place. Each article harnesses a critical Indigenous perspective in order to challenge conservative approaches or positions, be they concerned with reconciliation, Indigenous-led research, research tools or the nature of Aboriginal being. The first article, by Barry Judd and Emma Barrow, examines reconciliation discourse within the higher education sector and highlights the ways a normative Anglo-Australian identity militates against genuine ‘whitefella’ attempts to ‘reconcile’. The authors stress the importance of inclusive, institutional practice that serves to decentre Anglo-centrism and which, in turn, brings Indigenous peoples more fully into the fold of Australian university life.

Editorial of "International Journal of Critical Indigenous Studies, Volume 8, Number 1, 2015"

This edition includes a diverse range of contributions that collectively illustrate two elevated concerns of critical Indigenous studies: First, an interest in establishing ways and means of conducting ethical research with Indigenous communities; and second, critically engaging with constructions of Indigeneity. The first article, by Craig Sinclair, Peter Keelan, Samuel Stokes, Annette Stokes and Christine Jefferies-Stokes, examines the increasingly popular use of participatory video (PV) as a means of engagement, in this case with children in remote Aboriginal communities as participants in health research. The authors note that, whilst not without methodological disadvantages, the PV method, with its flexibility to respond to community priorities is particularly well suited to research with remote Aboriginal communities.

The articles in this edition address two critical concerns that can be broadly characterised as Indigeneity as a spectacle and the elision of Indigenous sovereignty by multiculturalism and diversity. The first article, by Maryrose Casey, examines nineteenth and early twentieth century Indigenous performances that drew on cultural practices for entertainment. She highlights how these commercially driven performances were, in fact, demonstrations of sovereignty that white colonisers paid to observe. A measure of the success of these demonstrations can be found in the reactions of audiences, which often involved disrupting the spectacle by physically occupying the performance space.

This special edition of the International Journal of Critical Indigenous Studies focuses upon the work scholars within the growing discipline of Aboriginal and Torres Strait Islander health studies. The lamentable state of Indigenous health in Australia is reflected in Indigenous populations elsewhere, especially where settler colonialism has left an indelible mark. This special edition therefore speaks to where Indigenous health outcomes and the efficacy of remedies are causing concern. Common to all is the demand that Indigenous people are placed front and centre of all attempts to improve health outcomes and that improvements are sought in culturally sensitive ways. Terry Dunbar presents findings from a research study that set out to investigate the Indigenous experiences of health and family services in the Northern Territory, Australia. The study asserts that cultural security is an integral and vital element of any policy that will impact upon Indigenous peoples. Dunbar concludes by arguing that in seeking positive change with regard to cultural security or otherwise, the most vociferous champions of that change are likely to be the Aboriginal communities affected. The article by Bronwyn Fredericks, Karen Adams, Sandra Angus and Melissa Walker also highlights the need to involve Aboriginal and Torres Strait Islander people, in this case women, in the design and development of strategies affecting their lives. Utilising routine communication methods such the ‘talking circle’ and the process referred to as ‘talkin’ up’, where women ‘talk back’ to one another about issues of personal importance, the article argues that the health strategy which emerged through these consultation approaches was more accurately informed by and responsive to women’s health need. Indeed, the resulting strategy reflected the women’s sense of themselves and the clear direction they felt their health services and polices should take.

Taxonomy of factors which influence heavy metal build-up on urban road surfaces

Heavy metals build-up on urban road surfaces is a complex process and influenced by a diverse range of factors. Although numerous research studies have been conducted in the area of heavy metals build-up, limited research has been undertaken to rank these factors in terms of their influence on the build-up process. This results in limitations in the identification of the most critical factor/s for accurately estimating heavy metal loads and for designing effective stormwater treatment measures. The research study undertook an in-depth analysis of the factors which influence heavy metals build-up based on data generated from a number of different geographical locations around the world. Traffic volume was found to be the highest ranked factor in terms of influencing heavy metals build-up while land use was ranked the second. Proximity to arterial roads, antecedent dry days and road surface roughness has a relatively lower ranking. Furthermore, the study outcomes advances the conceptual understanding of heavy metals build-up based on the finding that with increasing traffic volume, total heavy metal build-up load increases while the variability decreases. The outcomes from this research study are expected to contribute to more accurate estimation of heavy metals build-up loads leading to more effective stormwater treatment design.

Molecular dynamics simulations of CXCL-8 and its interactions with a receptor peptide, heparin fragments, and sulfated linked cyclitols

CXCL-8 (Interleukin 8) is a CXC chemokine with a central role in the human immune response. We have undertaken extensive in silico analyses to elucidate the interactions of CXCL-8 with its various binding partners, which are crucial for its biological function. Sequence and structure analyses showed that residues in the thirdq β-sheet and basic residues in the heparin binding site are highly variable, while residues in the second β-sheet are highly conserved. Molecular dynamics simulations in aqueous solution of dimeric CXCL-8 have been performed with starting geometries from both X-ray and NMR structures showed shearing movements between the two antiparallel C-terminal helices. Dynamic conservation analyses of these simulations agreed with experimental data indicating that structural differences between the two structures at quaternary level arise from changes in the secondary structure of the N-terminal loop, the 310-helix, the 30s, 40s, and 50s loops and the third β-sheet, resulting in a different interhelical separation. Nevertheless, the observation of these different states indicates that CXCL-8 has the potential to undergo conformational changes, and it seems likely that this feature is relevant to the mode of binding of glycosaminoglycan (GAG) mimetics such as cyclitols. Simulations of the receptor peptide fragment−CXCL-8 complex identified several specific interactions of the receptor peptide with CXCL-8 that could be exploited in the structure-based design of competitive peptides and nonpeptidic molecules targeting CXCL-8 for combating inflammatory diseases. Simulations of the CXCL-8 dimer complexed with a 24-mer heparin fragment and of the CXCL-8−receptor peptide complex revealed that Arg60, Lys64, and Arg68 in the dimer bind to cyclitols in a horseshoe pattern, defining a region which is spatially distinct from the receptor binding site. There appears to be an optimum number of sulfates and an optimum length of alkyl spacers required for the interaction of cyclitol inhibitors with the dimeric form of CXCL-8. Calculation of the binding affinities of cyclitol inhibitors reflected satisfactorily the ranking of experimentally determined inhibitory potencies. The findings of these molecular modeling studies will help in the search for inhibitors which can modulate various CXCL-8 biological activities and serve as an excellent model system to study CXC-inhibitor interactions.

Relative ranking: A biased rating

Reviewers' ratings have become one of the most influential parameters when making a decision to purchase or rent the products or services from the online vendors. Star Rating system is the de-facto standard for rating a product. It is regarded as one of the most visually appealing rating systems that directly interact with the consumers; helping them find products they will like to purchase as well as register their views on the product. It offers visual advantage to pick the popular or most rated product. Any system that is not as appealing as star system will have a chance of rejection by online business community. This paper argues that, the visual advantage is not enough to declare star rating system as a triumphant, the success of a ranking system should be measured by how effectively the system helps customers make decisions that they, retrospectively, consider correct. This paper argues and suggests a novel approach of Relative Ranking within the boundaries of star rating system to overcome a few inherent disadvantages the former system comes with. © Springer Science+Business Media B.V. 2010.
