Mixed methods research approach to the development and review of competency standards for dietitians

Aim: Competency standards support a range of professional activities including the accreditation of university courses. Reviewing these standards is essential to ensure universities continue to produce well equipped graduates, who can meet the challenge of changing workforce requirements. This paper has two aims: a) to provide an overview of the methodological approaches utilised for compilation and review of the Competency Standards for Dietetics and b) to evaluate the Dietitians Association of Australia’s Competency Standards and capture emerging and contemporary dietetic practice. Methods: A literature review of the methods used to develop Competency Standards for dietitians in Australia, including entry level, advanced level and DAA Fellow competencies and other specific areas of competency, such as public health nutrition and nutrition education is outlined and compared to other allied health professions. The mixed methods methodology used in the most recent review is described in more detail. Results: The history of Dietetic Competency Standards development and review in Australia is compared to dietetic Competency Standards internationally and within other health professions in Australia. The political context in which these standards have been developed in Australia and which has determined their format is also discussed. The results of the most recent Competency Standards review are reported to highlight emerging practice in Australia. Conclusion: The mixed methods approach used in this review provides rich data about contemporary dietetic practice. Our view supports a planned review of all Competency Standards to ensure practice informs education and credentialling and we recommend the Dietitians Association of Australia consider this in future

Twitter as a technology for audiencing and fandom : the #Eurovision phenomenon

Amongst the most prominent uses of Twitter at present is its role in the discussion of widely televised events: Twitter’s own statistics for 2011, for example, list major entertainment spectacles (the MTV Music Awards, the BET Awards) and sports matches (the UEFA Champions League final, the FIFA Women’s World Cup final) amongst the events generating the most tweets per second during the year (Twitter, 2011). User activities during such televised events constitute a specific, unique category of Twitter use, which differs clearly from the other major events which generate a high rate of tweets per second (such as crises and breaking news, from the Japanese earthquake and tsunami to the death of Steve Jobs), as preliminary research has shown. During such major media events, by contrast, Twitter is used most predominantly as a technology of fandom instead: it serves in the first place as a backchannel to television and other streaming audiovisual media, enabling users offer their own running commentary on the universally shared media text of the event broadcast as it unfolds live. Centrally, this communion of fans around the shared text is facilitated by the use of Twitter hashtags – unifying textual markers which are now often promoted to prospective audiences by the broadcasters well in advance of the live event itself. This paper examines the use of Twitter as a technology for the expression of shared fandom in the context of a major, internationally televised annual media event: the Eurovision Song Contest. It constitutes a highly publicised, highly choreographed media spectacle whose eventual outcomes are unknown ahead of time and attracts a diverse international audience. Our analysis draws on comprehensive datasets for the ‘official’ event hashtags, #eurovision, #esc, and #sbseurovision. Using innovative methods which combine qualitative and quantitative approaches to the analysis of Twitter datasets containing several hundreds of thousands, we examine overall patterns of participation to discover how audiences express their fandom throughout the event. Minute-by-minute tracking of Twitter activity during the live broadcasts enables us to identify the most resonant moments during each event; we also examine the networks of interaction between participants to detect thematically or geographically determined clusters of interaction, and to identify the most visible and influential participants in each network. Such analysis is able to provide a unique insight into the use of Twitter as a technology for fandom and for what in cultural studies research is called ‘audiencing’: the public performance of belonging to the distributed audience for a shared media event. Our work thus contributes to the examination of fandom practices led by Henry Jenkins (2006) and other scholars, and points to Twitter as an important new medium facilitating the connection and communion of such fans.

Diagnostic Dilemmas in Comorbidity

This high prevalence of comorbid mental health and substance use disorders makes the accurate diagnosis of comorbid disorders an important clinical priority. However, the presence of comorbid disorders creates a number of diagnostic dilemmas, which have hindered our understanding of the comorbid disorders. This chapter discusses these diagnostic dilemmas, including issues with the reliability, validity and clinical utility of current systems of psychiatric nomenclature’s approach to diagnosing comorbid disorders. A number of alternative models for understanding comorbid disorders are briefly discussed, followed by suggestions for how research can improve our understanding of comorbid disorders.

Poorly graphitized carbon as a new cosmothermometer for primitive extraterrestrial materials

The presence of carbon in primitive extraterrestrial materials has long been considered a useful indicator of prevailing geochemical conditions early in the formation of the Solar System. A recent addition to the suite of primitive materials available for study by cosmochemists includes particles collected from the stratosphere called chondritic porous (CP) aggregates1. Carbon-rich CP aggregates are less abundant in stratospheric collections and contain many low-temperature phases (such as layer silicates) as minor components2,3. We describe here the nature of the most abundant carbon phase in a carbon-rich CP aggregate (sample no. W7029* A) collected from the stratosphere as part of the Johnson Space Center (JSC) Cosmic Dust Program4. By comparison with experimental and terrestrial studies of poorly graphitized carbon (PGC), we show that the graphitization temperature, or the degree of ordering in the PGC, may provide a useful cosmothermometer for primitive extraterrestrial materials.

Ideal victims in human trafficking awareness campaigns

Amidst a proliferation of bestseller books, blockbuster films, television documentaries and sensational news reports, public awareness campaigns have claimed their place in a growing chorus of concern about the crime of human trafficking. These campaigns aim to capture the public’s support in efforts to eliminate a ‘modern slave trade’ in which individuals seeking a better life are transported across borders and forced into exploitative labour conditions. Constrained by the limitations of primary campaign materials (posters, print ads, billboards) typically allowing for only a single image and minimal text, it is unlikely that these awareness campaigns can accurately convey the complexity of the trafficking problem. This chapter explores how the depictions of trafficking victims in awareness campaigns can exclude those who do not fit a restrictive narrative mould. Nils Christie’s pivotal work on the construction of society’s ideal victim is the lens through which this paper examines the literal ‘poster child’ of the anti-trafficking movement.

Bilingual asynchronous online discussion groups : design and delivery of an e-Learning distance study module for nurse academics in a developing country

The advent of eLearning has seen online discussion forums widely used in both undergraduate and postgraduate nursing education. This paper reports an Australian university experience of design, delivery and redevelopment of a distance education module developed for Vietnamese nurse academics. The teaching experience of Vietnamese nurse academics is mixed and frequently limited. It was decided that the distance module should attempt to utilise the experience of senior Vietnamese nurse academics - asynchronous online discussion groups were used to facilitate this. Online discussion occurred in both Vietnamese and English and was moderated by an Australian academic working alongside a Vietnamese translator. This paper will discuss the design of an online learning environment for foreign correspondents, the resources and translation required to maximise the success of asynchronous online discussion groups, as well as the rationale of delivering complex content in a foreign language. While specifically addressing the first iteration of the first distance module designed, this paper will also address subsequent changes made for the second iteration of the module and comment on their success. While a translator is clearly a key component of success, the elements of simplicity and clarity combined with supportive online moderation must not be overlooked.

Electron paramagnetic resonance, optical absorption and Raman spectral studies on a pyrite/chalcopyrite mineral

Pyrite and chalcopyrite mineral samples from Mangampet barite mine, Kadapa, Andhra Pradesh, India are used in the present study. XRD data indicate that the pyrite mineral has a face centered cubic lattice structure with lattice constant 5.4179 Å. Also it possesses an average particle size of 91.9 nm. An EPR study on the powdered samples confirms the presence of iron in pyrite and iron and Mn(II) in chalcopyrite. The optical absorption spectrum of chalcopyrite indicates presence of copper which is in a distorted octahedral environment. NIR results confirm the presence of water fundamentals and Raman spectrum reveals the presence of water and sulfate ions.

The changing role of copyright in China’s emergent media economy

This chapter introduces the changing role of copyright in China from a historical perspective. It begins by briefly tracing the history of copyright, from a censorship-related system associated with the emergence of the printing press in imperial China, through modernisation during the Republican period, abolition under communism and finally to the introduction of the People's Republic of China's (PRC) first copyright law in 1990 and the nation's entry into the World Trade Organisation (WTO) in 2001.

The BRICS and the responsibility to protect : lessons from the Libyan and Syrian crises

The emerging ‘responsibility to protect’ (R2P) principle presents a significant challenge to the BRICS (Brazil, Russia, India, China and South Africa) states’ traditional emphasis on a strict Westphalian understanding of state sovereignty and non-interference in domestic affairs. Despite formally endorsing R2P at the 2005 World Summit, each of the BRICS has, to varying degrees, retained misgivings about coercive measures under the doctrine’s third pillar. This paper examines how these rising powers engaged with R2P during the 2011–2012 Libyan and Syrian civilian protection crises. The central finding is that although all five states expressed similar concerns over NATO’s military campaign in Libya, they have been unable to maintain a common BRICS position on R2P in Syria. Instead, the BRICS have splintered into two sub-groups. The first, consisting of Russia and China, remains steadfastly opposed to any coercive measures against Syria. The second, comprising the democratic IBSA states (India, Brazil and South Africa) has displayed softer, more flexible stances towards proposed civilian protection measures in Syria, although these three states also remain cautious about the implementation of R2P’s coercive dimension. This paper identifies a number of factors which help to explain this split, arguing that the failure to maintain a cohesive BRICS position on R2P is unsurprising given the many internal differences and diverging national interests between the BRICS members. Overall, the BRICS’ ongoing resistance to intervention is unlikely to disappear quickly, indicating that further attempts to operationalize R2P’s third pillar may prove difficult.

Vibrational spectroscopy of the phosphate mineral kovdorskite – Mg2PO4(OH)⋅3H2O

The mineral kovdorskite Mg2PO4(OH)�3H2O was studied by electron microscopy, thermal analysis and vibrational spectroscopy. A comparison of the vibrational spectroscopy of kovdorskite is made with other magnesium bearing phosphate minerals and compounds. Electron probe analysis proves the mineral is very pure. The Raman spectrum is characterized by a band at 965 cm�1 attributed to the PO3� 4 m1 symmetric stretching mode. Raman bands at 1057 and 1089 cm�1 are attributed to the PO3�4 m3 antisymmetric stretching modes. Raman bands at 412, 454 and 485 cm�1 are assigned to the PO3�4 m2 bending modes. Raman bands at 536, 546 and 574 cm�1 are assigned to the PO3�4 m4 bending modes. The Raman spectrum in the OH stretching region is dominated by a very sharp intense band at 3681 cm�1 assigned to the stretching vibration of OH units. Infrared bands observed at 2762, 2977, 3204, 3275 and 3394 cm�1 are attributed to water stretching bands. Vibrational spectroscopy shows that no carbonate bands are observed in the spectra; thus confirming the formula of the mineral as Mg2PO4(OH)�3H2O.

The architecture of children’s use of language and tools when problem solving collaboratively with robotics

This paper demonstrates, following Vygotsky, that language and tool use has a critical role in the collaborative problem-solving behaviour of school-age children. It reports original ethnographic classroom research examining the convergence of speech and practical activity in children’s collaborative problem solving with robotics programming tasks. The researchers analysed children’s interactions during a series of problem solving experiments in which Lego Mindstorms toolsets were used by teachers to create robotics design challenges among 24 students in a Year 4 Australian classroom (students aged 8.5–9.5 years). The design challenges were incrementally difficult, beginning with basic programming of straight line movement, and progressing to more complex challenges involving programming of the robots to raise Lego figures from conduit pipes using robots as pulleys with string and recycled materials. Data collection involved micro-genetic analysis of students’ speech interactions with tools, peers, and other experts, teacher interviews, and student focus group data. Coding the repeated patterns in the transcripts, the authors outline the structure of the children’s social speech in joint problem solving, demonstrating the patterns of speech and interaction that play an important role in the socialisation of the school-age child’s practical intellect.

Living with the Legacy of Conquest and Culture : Social Justice Leadership in Education and the Indigenous Peoples of Australia and America

Indigenous peoples have survived the most inhumane acts and violations against them. Despite acts of genocide, Aboriginal Australians and Native Americans have survived. The impact of the past 500 years cannot be separated from understandings of education for Native Americans in the same way that the impact of the past 220 years cannot be separated from the understandings of Australian Aboriginal people’s experiences of education. This chapter is about comparisons in Aboriginal and Native American communities and their collision with the dominant, white European settlers who came to Australia and America. Chomsky (Intervention in Vietnam and Central America: parallels and differences. In: Peck J (ed) The Chomsky Reader. Pantheon Books, New York, p 315, 1987) once remarked that if one took two historical events and compared them for similarities and differences, you would find both. The real test was whether on the similarities they were significant. The position of the coauthors of this chapter is in the affirmative and we take this occasion to lay them out for analysis and review. The chapter begins with a discussion of the historical legacy of oppression and colonization impacting upon Indigenous peoples in Australia and in the United States, followed by a discussion of the plight of Indigenous children in a specific State in America. Through the lens of social justice, we examine those issues and attitudes that continue to subjugate these same peoples in the economic and educational systems of both nations. The final part of the chapter identifies some implications for school leadership.

Studies on the pathophysiology and genetic basis of migraine

Migraine is a neurological disorder that affects the central nervous system causing painful attacks of headache. A genetic vulnerability and exposure to environmental triggers can influence the migraine phenotype. Migraine interferes in many facets of people’s daily life including employment commitments and their ability to look after their families resulting in a reduced quality of life. Identification of the biological processes that underlie this relatively common affliction has been difficult because migraine does not have any clearly identifiable pathology or structural lesion detectable by current medical technology. Theories to explain the symptoms of migraine have focused on the physiological mechanisms involved in the various phases of headache and include the vascular and neurogenic theories. In relation to migraine pathophysiology the trigeminovascular system and cortical spreading depression have also been implicated with supporting evidence from imaging studies and animal models. The objective of current research is to better understand the pathways and mechanisms involved in causing pain and headache to be able to target interventions. The genetic component of migraine has been teased apart using linkage studies and both candidate gene and genome-wide association studies, in family and case-control cohorts. Genomic regions that increase individual risk to migraine have been identified in neurological, vascular and hormonal pathways. This review discusses knowledge of the pathophysiology and genetic basis of migraine with the latest scientific evidence from genetic studies.

Variants in the human potassium channel gene (KCNN3) are associated with migraine in a high risk genetic isolate

The calcium-activated potassium ion channel gene (KCNN3) is located in the vicinity of the familial hemiplegic migraine type 2 locus on chromosome 1q21.3. This gene is expressed in the central nervous system and plays a role in neural excitability. Previous association studies have provided some, although not conclusive, evidence for involvement of this gene in migraine susceptibility. To elucidate KCNN3 involvement in migraine, we performed gene-wide SNP genotyping in a high-risk genetic isolate from Norfolk Island, a population descended from a small number of eighteenth century Isle of Man ‘Bounty Mutineer’ and Tahitian founders. Phenotype information was available for 377 individuals who are related through the single, well-defined Norfolk pedigree (96 were affected: 64 MA, 32 MO). A total of 85 SNPs spanning the KCNN3 gene were genotyped in a sub-sample of 285 related individuals (76 affected), all core members of the extensive Norfolk Island ‘Bounty Mutineer’ genealogy. All genotyping was performed using the Illumina BeadArray platform. The analysis was performed using the statistical program SOLAR v4.0.6 assuming an additive model of allelic effect adjusted for the effects of age and sex. Haplotype analysis was undertaken using the program HAPLOVIEW v4.0. A total of four intronic SNPs in the KCNN3 gene displayed significant association (P < 0.05) with migraine. Two SNPs, rs73532286 and rs6426929, separated by approximately 0.1 kb, displayed complete LD (r 2 = 1.00, D′ = 1.00, D′ 95% CI = 0.96–1.00). In all cases, the minor allele led to a decrease in migraine risk (beta coefficient = 0.286–0.315), suggesting that common gene variants confer an increased risk of migraine in the Norfolk pedigree. This effect may be explained by founder effect in this genetic isolate. This study provides evidence for association of variants in the KCNN3 ion channel gene with migraine susceptibility in the Norfolk genetic isolate with the rarer allelic variants conferring a possible protective role. This the first comprehensive analysis of this potential candidate gene in migraine and also the first study that has utilised the unique Norfolk Island large pedigree isolate to implicate a specific migraine gene. Studies of additional variants in KCNN3 in the Norfolk pedigree are now required (e.g. polyglutamine variants) and further analyses in other population data sets are required to clarify the association of the KCNN3 gene and migraine risk in the general outbred population.

Copyrights and copyfights : copyright law and the digital economy

This paper will consider questions around the reform of copyright law, and how they are increasingly being framed by the challenges of the digital economy. It discusses the review of copyright and the digital economy being undertaken by the Australian Law Reform Commission, with particular reference to the costs and benefits of copyright law to consumers and creative producers. We argue that there is a pressing need to develop fair copyright rules that encourage investment in the digital economy, allow widespread dissemination of knowledge through society, and support the innovative reuse of copyright works. To better align copyright law with these goals, we recommend that Australia introduce an open ended ‘fair use’ style copyright exception, and encourage the development of a digital copyright exchange of the sort discussed in the UK by the Hargreaves and Hooper Reports.
