The term moral panic has entered the media and popular culture lexicon, but retains a particular meaning for sociologists. This chapter expands on existing models of moral panics and outlines a case study that illustrates that folk devils have fought back in recent years, using technologies such as social media to present their arguments (in this instance, turning a local political controversy in Melbourne, the Australian state of Victoria, to their advantage). The battle began over a classice law-and-order issue, that is, the problem of  alcohol-related violence, expecially as it involves young people. However, the conflict took an unexpected turn when the fold devils successfully used the media to prosecute their case and force the state government's hand.

Using a grounded theory approach, this paper extracts emerging concepts in the implementation of green supply chain management from case data of New Zealand food and beverage (F&B) companies. In search of factors that may lead to theory-building, the study relates case studies in fruit, juice, and dairy product companies through in-depth interviews with ranking general and line managers. We uncover the outline of a theoretical framework focusing on determinants of GSCM behaviour. These include strategic and operational planning; management structure, systems, and decision-making; management of people and company culture; and relationships with supply-chain members.

Feasting on North American moose or Caribbean turtle in Renaissance Italy, Ancient Rome, or the colonial working-class pub, is Social and Cultural history in a new and exciting form. Dining on Turtles traverses time and place to open up food and drink as a new field of historical enquiry. In chapters covering the heritage landscapes of sugar canefields, the reform of popular drinking customs, the importance of eating and drinking culture to Olympic Games planning, and the significance of cookbooks to civic society, historians here break new ground in locating food's importance. From the exploration of French tavern rituals, Scottish feasting on haggis, and memories of food traditions in Cyprus come themes of identity and nationalism, change and continuity.

The vast majority of novels and periodicals read by colonial Australian girls were written and published in Britain. ‘Daughters of the Southern Cross’ were more likely to have access to the Girl’s Own Paper by subscription or to imported fictions that had proven popular with British girl readers than any locally produced depictions of girlhood. From the 1880s, however, Australian authors produced several milestone fictions of girlhood for both adult and juvenile audiences. Rosa Praed's An Australian Heroine (1880) and Catherine Martin’s An Australian Girl (1890)  gave voice to the lived experience of Australia for young women, and their publication in Britain contributed to an emergent reciprocal transpacific flow of literary culture.

Two canonical Australian novels that focus on the maturation of girl protagonists who live on bush homesteads were also published in this period. Ethel Turner’s Seven Little Australians (1894) and Miles Franklin’s My Brilliant Career (1901) feature intelligent girls who are not able to be effectively socialised to embrace domesticity. Turner’s Judy Woolcot is distinct among her six siblings as a plucky girl who instigates trouble, while Franklin’s aspiring writer Sybylla Melvyn is informed that ‘girls are the helplessest, uselessest, troublesomest little creatures in the world.’

The 1890s saw an agricultural depression in Australia that only fuelled the urban perpet-uation of the idealised and nationalistic bushman myth in literary and popular culture. The ubiquity of the myth problematised any attempt to situate women heroically within the nation outside of the home. British fictional imaginings of Australian girls lauded their lack of conformity and physical abilities and often showed them bravely defending the family property with firearms. In contrast, Australian domestic fiction, this chapter argues, is unable to accommodate bracing female heroism, postulating ambiguous outcomes at best for heroines who deviate from the feminine ideal.

Judy’s grandmother describes her ‘restless fire’ as something that ‘would either make a noble, daring, brilliant woman of her’, or ‘would flame up higher and higher and consume her’. Turner does not allow Judy’s unconventionality to prosper. Instead, she is killed by a falling gum tree while saving the life of her brother, leaving the future fulfilment of the domestic ideal to her sister, Meg, whose subsequent story occupies Little Mother Meg (1902). Franklin’s Sybylla expresses her inability to be content with the simple pleasures of keeping a home, and this informs her decision to reject a marriage proposal from a wealthy suitor. The novel’s indeterminate conclusion does not allow fulfilment of Sybylla’s writing aspirations, situating her outside the feminine ideal yet not affirming the merits of her desire to reject married life.

While Sharyn Pearce suggests that Judy’s tragic end follows a narrative pattern that sup-ports the glorification of male heroes and renders ‘over-reaching women’ as ‘noble failures’, the novel might also productively be read within the context of other fictions featuring girl protagonists of the period, such as Praed and Martin's novels. This chapter makes the case that Turner and Franklin’s thwarted heroines critique the containment of Australian girls to the banalities of the home by exposing the negative and uncertain outcomes for those who desire the freedoms and aspirations permitted to boys and men. Unlike British fictions that champion adventurous girls, these Australian fictions critique the continuation of gendered restrictions in the colonies by proposing that girls who desire excitement and independence ‘should have been…boy[s]’ (as Sybylla’s mother remarks).

 Persona is a public presentation of identity. One of the key values of a persona is its consistency in its presentation of the self. This article is designed to be the first exploratory steps and overview in charting the idea of seriality in relation to persona and its utility as a concept to describe the constancy and transformation of identity that is now elemental to understanding contemporary persona or the public presentation of the self and its online manifestations. Seriality in terms of persona is first investigated from its entertainment culture origins – with its use in the constitution of characters in fiction in novels, films, games and most prevalently in television. Several examples of serial persona will be analysed with an emphasis on how television has constructed often the most powerful personas: Kevin Spacey’s persona as Frank Underwood in House of Cards is discussed in greater detail in terms of the economic, cultural and affective value of serial persona and its associated formations of risk. It then explores the blending of the fictional and the real in seriality through how popular music performers – in particular Eminem - construct an authentic register of persona to allow for the exploration of the self through emotion and connection. The article concludes with thinking how seriality is connected to the constitutions of online identity and links the concept with aspects of virality and meme culture and their constructions of value, patterns and constancy as it relate to the presentation of the public self.

Australia has a diverse, multilayered society that reflects its rich musical life. There are many community choirs formed by various cultural and linguistically diverse groups. This article is part of an ongoing project, Well-being and ageing: community, diversity and the arts (since 2008), undertaken by Deakin University and Monash University, that explores the cultural diversity within Australian society and how active music engagement fosters well-being. The singing groups selected for this discussion are the Skylarkers, the Bosnian Behar Choir, and the Coro Furlan. The Skylarkers and the Bosnian Behar Choir are mixed groups who respectively perform popular music from their generation and celebrate their culture through music. The Coro Furlan is an Italian male choir who understand themselves as custodians of their heritage. In these interpretative, qualitative case studies semi-structured interviews were undertaken and analyzed using Interpretative Phenomenological Analysis. In this approach there is an exploration of participants’ understanding of their lived experiences. The analysis of the combined data identified musical and social benefits that contribute to participants’ sense of individual well-being. Musical benefits occurred through sharing, learning and singing together. Social benefits included opportunities to build friendships, overcome isolation and gain a sense of validation. Many found that singing enhanced their health and happiness. Active music making in community choirs and music ensembles continues to be an effective way to support individuals, build community, and share culture and heritage.

The literature on how to improve Indigenous access to early childhood services consists mainly of program descriptions and documented practice experience, with a limited number of formal program evaluations. Accessible early childhood services fulfil four overlapping dimensions. They are physically accessible; economically accessible (affordable); appropriate (comprehensive and non-discriminatory); and acceptable (respect and acknowledge culture).The literature suggests that there are five types of barriers to accessible early childhood services: individual; program; provider; social and neighbourhood; and cultural.It is not sufficient to just improve access—engagement strategies are also necessary to get families involved in the services that may benefit them.

Identification of extracellular conductive pilus-like structures (PLS) i.e. microbial nanowires has spurred great interest among scientists due to their potential applications in the fields of biogeochemistry, bioelectronics, bioremediation etc. Using conductive atomic force microscopy, we identified microbial nanowires in Microcystis aeruginosa PCC 7806 which is an aerobic, photosynthetic microorganism. We also confirmed the earlier finding that Synechocystis sp. PCC 6803 produces microbial nanowires. In contrast to the use of highly instrumented continuous flow reactors for Synechocystis reported earlier, we identified simple and optimum culture conditions which allow increased production of nanowires in both test cyanobacteria. Production of these nanowires in Synechocystis and Microcystis were found to be sensitive to the availability of carbon source and light intensity. These structures seem to be proteinaceous in nature and their diameter was found to be 4.5-7 and 8.5-11 nm in Synechocystis and M. aeruginosa, respectively. Characterization of Synechocystis nanowires by transmission electron microscopy and biochemical techniques confirmed that they are type IV pili (TFP) while nanowires in M. aeruginosa were found to be similar to an unnamed protein (GenBank : CAO90693.1). Modelling studies of the Synechocystis TFP subunit i.e. PilA1 indicated that strategically placed aromatic amino acids may be involved in electron transfer through these nanowires. This study identifies PLS from Microcystis which can act as nanowires and supports the earlier hypothesis that microbial nanowires are widespread in nature and play diverse roles.

Early childhood educators currently provide content focused learning opportunities for children in the areas of well-being and environmental education. However, these are usually seen as discrete content areas and educators are challenged with responding to children’s interests in popular-culture inspired food products given these influence their consumption of energy-dense, nutrient-poor and highly packaged food in the early childhood setting. This paper reports preliminary findings from a pilot randomised trial examining the interconnectedness of sustainability, well-being and popular-culture in early childhood education. Planning, assessment documentation and summaries from twenty-four learning experiences implemented by six educators over a six-week period were analysed using a deductive approach. Twenty well-being and environmental education topics were identified and shown to be generated by the educators when considering the children’s ‘funds of knowledge’ on popular-culture inspired food products. We argue that topics derived from children’s engagement with popular-culture may help educators to create an integrated approach to curriculum provision. This may impact child weight and facilitate obesity prevention and environmental sustainability as children create stronger connections between these content areas and their everyday choices and practices.

Manipur, a small state in the North-Eastern corner of India, is traditionally regarded as the home of gandharvas (the celestial dancers). Manipuri is one of the 11 dance styles recognized by the Ministry of Culture of India that have incorporated various key techniques mentioned in the ancient treatises like the Natya Shastra and Bharatarnava and has been placed under 'a common heritage' called Indian classical dance forms (shastriya nritya) - Bharata Natyam, Kathak, Kathakali, Kuchipudi, Manipuri, Mohiniyattam, Odissi, Sattriya, Chhau, Gaudiya Nritya, and Thang Ta. In 1951 Louise Lightfoot, the 'Australian mother of Kathakali' dance, visited the remote mountain state of Manipur to learn more about Manipuri dance. Soon she was successful in persuading and bringing eminent exponents of Manipuri dancing style Jagoi, Rajkumar Priyagopal Singh and Lakshman Singh, to tour Australia. Priyagopal, with the help of Lightfoot and their international tours, to some extent, de-provincialized and also popularized the Manipuri dance and paved the way for other dancers from North-eastern region of India in the International art world. Through this paper I attempt to highlight the contribution of Lightfoot in the promotion of Manipuri dance and in Australia. I here also engage explicitly with Priyagopal and Lightfoot's unusual dance collaboration and trace the historical journey and reception of a Manipuri dance in Australia. © 2014 © 2014 Taylor & Francis.

Australian universities have traditionally been able to supplement clinical education, for undergraduate nursing courses, delivered on placement with weekly clinical teaching in the simulated environment. The Objective Structured Clinical Assessment (OSCA) tool has been used in this simulated environment to assess clinical skills. Recently, however, online delivery of undergraduate nursing courses has become more common. The move from an internal mode of teaching to an online external mode is seen worldwide and poses challenges to staff and students as well as changing the teaching and learning culture of institutions (Philip and Wozniak, 2009). This cultural shift and the resulting diminishing timeframe for students to acquire and practice simulated clinical skills imply that it may become necessary to rethink assessment forms such as the OSCA assessment. This study examines whether or not the OSCA tool developed by Bujack et al. (1991a) is the best tool to be used in this new context, where online teaching is supplemented by very short, annual, intensive periods of study. Skills acquisition theories dictate that time is required to produce an ideal skills acquisition environment (Quinn, 2000) but the time constraints placed on students in such intensive periods of study could influence skills acquisition. This cross-sectional qualitative study used semi-structured interviews and focus groups to collect data. 65% of the nursing faculty participated in the study. The teaching of the Bachelor of Nursing (BN) occurred on two campuses and staff from both areas participated. This group of nurse academics was employed across the range of academic levels (from lecturer to professor) at the University. Data analysis followed a generic thematic analysis framework. Findings in this study show that there are a variety of attitudes and underpinning beliefs amongst staff in relation to the OSCAs. Doubts were raised in regard to the suitability of the use of the OSCA tool in this setting. It also became apparent during this study that the OSCA tool possibly serves purposes other than an assessment tool.

Aims: Little is known about the social and functional aspects of alcohol mixed with energy drink(AmED) consumption. Using a functional substance use perspective and via the lens of socialidentity theory, this paper aims to explore the role of AmED consumption amongst the milieuof nightlife and party culture. Methods: Twenty-five regular AmED consumers aged 18–33participated in semi-structured interviews. Qualitative thematic analysis of transcripts wasundertaken, with a focus on the social contexts and perceived functions of AmED consumption,group dynamics and social identity. Findings: Three main themes were identified: (i) AmED usewas restricted to specific social contexts, (ii) AmED use performed a social function and(iii) AmED users identified with a coherent and consistent social identity. AmED use was almostexclusively reported to occur within group drinking scenarios at parties and licensed venues,particularly nightclubs. AmED users identified with a clear and consistent social identity thatwas distinct from other alcohol consumers, typified by gregarious and extroverted behaviour.AmED use was seen to facilitate these ideals and strengthen group cohesion in appropriatecontexts. Conclusions: Future efforts aiming to elicit changes in AmED consumption practices must account for the fundamental importance of social contexts to AmED use.

Oxygen levels are an important variable during the in vitro culture of stem cells. There has been increasing interest in the use of low oxygen to maximize proliferation and, in some cases, effect differentiation of stem cell populations. It is generally assumed that the defined pO2 in the incubator reflects the pO2 to which the stem cells are being exposed. However, we demonstrate that the pO2 experienced by cells in static culture can change dramatically during the course of culture as cell numbers increase and as the oxygen utilization by cells exceeds the diffusion of oxygen through the media. Dynamic culture (whereby the cell culture plate is in constant motion) largely eliminates this effect, and a combination of low ambient oxygen and dynamic culture results in a fourfold increase in reconstituting capacity of human hematopoietic stem cells compared with those cultured in static culture at ambient oxygen tension. Cells cultured dynamically at 5% oxygen exhibited the best expansion: 30-fold increase by flow cytometry, 120-fold increase by colony assay, and 11% of human CD45 engraftment in the bone marrow of NOD/SCID mice. To our knowledge, this is the first study to compare individual and combined effects of oxygen and static or dynamic culture on hematopoietic ex vivo expansion. Understanding and controlling the effective oxygen tension experienced by cells may be important in clinical stem cell expansion systems, and these results may have relevance to the interpretation of low oxygen culture studies.
