Acoustic, electric and virtual noise : the cultural identity of the guitar

Guitar technology underwent significant changes in the 20th century in the move from acoustic to electric instruments. In the first part of the 21st century, the guitar continues to develop through its interaction with digital technologies. Such changes in guitar technology are usually grounded in what we might call the "cultural identity" of the instrument: that is, the various ways that the guitar is used to enact, influence and challenge sociocultural and musical discourses. Often, these different uses of the guitar can be seen to reflect a conflict between the changing concepts of "noise" and "musical sound."

Becoming a pharmacist : the role of curriculum in professional identity formation

Objective To understand how the formal curriculum experience of an Australian undergraduate pharmacy program supports students’ professional identity formation. Methods A qualitative ethnographic study was conducted over four weeks using participant observation and examined the ‘typical’ student experience from the perspective of a pharmacist. A one-week period of observation was undertaken with each of the four year groups (that is, for years one to four) comprising the undergraduate curriculum. Data were collected through observation of the formal curriculum experience using field notes, a reflective journal and informal interviews with 38 pharmacy students. Data were analyzed thematically using an a priori analytical framework. Results Our findings showed that the observed curriculum was a conventional curricular experience which focused on the provision of technical knowledge and provided some opportunities for practical engagement. There were some opportunities for students to imagine themselves as pharmacists, for example, when the lecture content related to practice or teaching staff described their approach to practice problems. However, there were limited opportunities for students to observe pharmacist role models, experiment with being a pharmacist or evaluate their professional identities. While curricular learning activities were available for students to develop as pharmacists e.g. patient counseling, there was no contact with patients and pharmacist academic staff tended to role model as educators with little evidence of their pharmacist selves. Conclusion These findings suggest that the current conventional approach to the curriculum design may not be fully enabling learning experiences which support students in successfully negotiating their professional identities. Instead it appeared to reinforce their identities as students with a naïve understanding of professional practice, making their future transition to professional practice challenging.

The body in grief : death investigations, objections to autopsy, and the religious and cultural 'other'

Sudden, violent and otherwise unexplained deaths are investigated in most western jurisdictions through a Coronial or medico-legal process. A crucial element of such an investigation is the legislative requirement to remove the body for autopsy and other medical interventions, processes which can disrupt traditional religious and cultural grieving practices. While recent legislative changes in an increasing number of jurisdictions allow families to raise objections based on religious and cultural grounds, such concerns can be over-ruled, often exacerbating the trauma and grief of families. Based on funded research which interviews a range of Coronial staff in one Australian jurisdiction, this paper explores the disjuncture between medico-legal discourses, which position the body as corpse, and the rise of more ‘therapeutic’ discourses which recognise the family’s wishes to reposition the body as beloved and lamented.

Cultural drivers of high performing knowledge-intensive service organisations

Organisational culture is considered an important influence on performance, particularly for service firms that rely on values-driven social controls to enhance human interactions (O’Reilly & Chatman, 1996). Using a qualitative approach, we show how the modified Organisational Culture Profile developed by Sarros, Gray, Densten, and Cooper (2005) to assess Australian organisations provides a framework for exploring the cultural drivers of high performing knowledge-intensive service firms in New Zealand. Our study provides rich insights into how six key cultural dimensions–competitiveness, innovation, performance orientation, emphasis on rewards, supportiveness and social responsibility–are translated into strategic human resource management practices.

Mechanical influences on endothelial cell network formation in vitro

While both the restoration of the blood supply and an appropriate local mechanical environment are critical for uneventful bone healing, their influence on each other remains unclear. Human bone fracture haematomas (<72h post-trauma) were cultivated for 3 days in fibrin matrices, with or without cyclic compression. Conditioned medium from these cultures enhanced the formation of vessel-like networks by HMEC-1 cells, and mechanical loading further elevated it, without affecting the cells’ metabolic activity. While haematomas released the angiogenesis-regulators, VEGF and TGF-β1, their concentrations were not affected by mechanical loading. However, direct cyclic stretching of the HMEC-1 cells decreased network formation. The appearance of the networks and a trend towards elevated VEGF under strain suggested physical disruption rather than biochemical modulation as the responsible mechanism. Thus, early fracture haematomas and their mechanical loading increase the paracrine stimulation of endothelial organisation in vitro, but direct periodic strains may disrupt or impair vessel assembly in otherwise favourable conditions.

More than simple living : a cultural perspective on sustainable living

This paper provides a cultural perspective to the sustainability research within HCI. I draw on the results from an ethnographic field study of sustainable household practices of ten women belonging to the so-called middle class in India. Focusing on their reuse practices, I provide examples of domestic artefacts that are creatively and resourcefully reused from worn-out artefacts. My initial findings show that the rationale behind creating such artefacts is not limited to the practicality and usefulness, but how cultural and religious beliefs are incorporated into such practices.

Potential interstellar molecules : Formation of neutral C6CO from C6CO- in the gas phase

Computations at the RCCSD(T)/aug-cc-pVDZ//B3LYP/6-31G* level of theory indicate that neutral C6CO is a stable species. The ground state of this neutral is the singlet cumulene oxide :C=C=C=C=C=C=C=O. The adiabatic electron affinity and dipole moment of singlet C6CO are 2.47 eV and 4.13 D, respectively, at this level of theory. The anion (C6CO)(-.) should be a possible precursor to this neutral. It has been formed by an unequivocal synthesis in the ion source of a mass spectrometer by the S(N)2(Si) reaction between (CH3)(3)Si-C=C-C=C-C=C-CO-CMe3 and F- to form C-=C-C=C-C=C-CO-CMe3 which loses Me3C in the source to form C6CO-.. Charge stripping of this anion by vertical Franck-Condon oxidation forms C6CO, characterised by the neutralisation-reionisation spectrum (-NR+) of C6CO-., which is stable during the timeframe of this experiment (10(-6) s), Copyright (C) 2000 John Wiley & Sons, Ltd.

Postcards from somewhere : ‘marginal’ cultural production, creativity and community

This paper focuses on a case study of local postcard production in a rural community in Western Australia. Drawing on in-depth interviews with key producers of these postcards, the analysis presented explores perceptions of and contexts for the emergence of this production, in turn examining the notion of ‘creativity’ articulated and privileged by this cultural work. Connections are identified between the making of postcards, the broader historical field of local cultural work and the construction of community. This, in turn, forms the basis for consideration of the role and relativity of ‘marginality’.

Doing cultural work : local postcard production and place identity in a rural shire

Studies of place construction in the rural studies literature have largely privileged the role of professionals over that of local lay actors. This paper contributes to redressing this imbalance through a critical case-study of lay postcard production in a rural shire. Drawing on original, qualitative research conducted in the Shire of Ravensthorpe, Western Australia, including in-depth interviews with key participants, the analysis focuses on this lay production—undertaken in the main by women—as cultural work. By emphasising the work of making the postcards along with the cultural work these postcards achieve, this examination foregrounds intersections of material and imagined ruralities. In the process, this study highlights the complexity and importance of this lay contribution to place identity, particularly as positioned within what may be considered rural cultural work.

Effect of culture conditions and calcium phosphate coating on ectopic bone formation

This study investigated the effect of a calcium phosphate (CaP) coating onto a polycaprolactone melt electrospun scaffold and in vitro culture conditions on ectopic bone formation in a subcutaneous rat model. The CaP coating resulted in an increased alkaline phosphatase activity (ALP) in ovine osteoblasts regardless of the culture conditions and this was also translated into higher levels of mineralisation. A subcutaneous implantation was performed and increasing ectopic bone formation was observed over time for the CaPcoated samples previously cultured in osteogenic media whereas the corresponding non-coated samples displayed a lag phase before bone formation occurred from 4 to 8 weeks post-implantation. Histology and immunohistochemistry revealed bone fill through the scaffolds 8 weeks post-implantation for coated and non-coated specimens and that ALP, osteocalcin and collagen 1 were present at the ossification front and in the bone tissues. Vascularisation in the vicinity of the bone tissues was also observed indicating that the newly formed bone was not deprived of oxygen and nutrients.We found that in vitro osteogenic induction was essential for achieving bone formation and CaP coating accelerated the osteogenic process. We conclude that high cell density and preservation of the collagenous and mineralised extracellular matrix secreted in vitro are factors of importance for ectopic bone formation.

Pushing cultural competence boundaries in nutrition and dietetics training

A health workforce ready for safe practice is a government priority, and particularly critical to support indigenous communities closing ‘the gap’. Increased pressure exists on dietetic training programs for quality placements, with fewer opportunities for immersion in Aboriginal and Torres Strait Islander communities to demonstrate cultural competence. In 2012, Queensland University of Technology established a partnership with Apunipima Cape York Health Council with 56 weeks of dietetic placement for 8 students provided to achieve these aims. Clinical practice in Community Public Health Nutrition (CPHN) was structured in a standard 6 week placement, with Individual Case Management (ICM) and Foodservice Management (FSM) integrated across 8 weeks (4 each), with an additional 2 weeks ICM prior in a metropolitan indigenous health service. Students transitioned from urban to rural then remote sites, with new web-based technologies used for support. Strong learning opportunities were provided, with CPHN projects in antenatal and child health, FSM on standardisation of procedures in a 22 bed health facility, and ICM exposing students to a variety of cases via hospital in/outpatients, general clinics and remote community outreach. Supervisor focus group evaluation was positive, with CPHN and FSM enhancing capacity of service. Student focus group evaluation revealed placements exceeded expectations, with rating high, and strong confidence in cultural competence described. Students debriefed final and third year cohorts on their experiences, with increased awareness and enthusiasm for work with indigenous communities indicated by groups. With the success of this partnership, placements are continuing 2013, and new boundaries in dietetic training established.

Formation of specialized propagules resistant to desiccation and cryopreservation in the threatened moss Ditrichum plumbicola (ditrichales, bryopsida)

Background and Aims Successful cryopreservation of bryophytes is linked to intrinsic desiccation tolerance and survival can be enhanced by pre-treatment with abscisic acid (ABA) and sucrose. The pioneer moss Ditrichum plumbicola is naturally subjected to desiccation in the field but showed unexpectedly low survival of cryopreservation, as well as a poor response to pre-treatment. The effects of the cryopreservation protocol on protonemata of D. plumbicola were investigated in order to explore possible relationships between the production in vitro of cryopreservation-tolerant asexual propagules and the reproductive biology of D. plumbicola in nature. Methods Protonemata were prepared for cryopreservation using a four-step protocol involving encapsulation in sodium alginate, pre-treatment for 2 weeks with ABA and sucrose, desiccation for 6 h and rapid freezing in liquid nitrogen. After each stage, protonemata were prepared for light and electron microscopy and growth on standard medium was monitored. Further samples were prepared for light and electron microscopy at intervals over a 24-h period following removal from liquid nitrogen and re-hydration. Key Results Pre-treatment with ABA and sucrose caused dramatic changes to the protonemata. Growth was arrested and propagules induced with pronounced morphological and cytological changes. Most cells died, but those that survived were characterized by thick, deeply pigmented walls, numerous small vacuoles and lipid droplets in their cytoplasm. Desiccation and cryopreservation elicited no dramatic cytological changes. Cells returned to their pre-dehydration and cryopreservation state within 2 h of re-hydration and/or removal from liquid nitrogen. Regeneration was normal once the ABA/sucrose stimulus was removed. Conclusions The ABA/sucrose pre-treatment induced the formation of highly desiccation- and cryopreservation-tolerant propagules from the protonemata of D. plumbicola. This parallels behaviour in the wild, where highly desiccation-tolerant rhizoids function as perennating organs allowing the moss to endure extreme environmental conditions. An involvement of endogenous ABA in the desiccation tolerance of D. plumbicola is suggested.

Mass spectrometric study of the dissociation of Group XI metal complexes with fatty acids and glycerolipids : Ag2H+ and Cu2H+ ion formation in the presence of a double bond

Results of mass spectrometric studies are reported for the collisional dissociation of Group XI (Cu, Ag, Au) metal ion complexes with fatty acids (palmitic, oleic, linoleic and a-linolenic) and glycerolipids. Remarkably, the formation of M2H+ ions (M = Cu, Ag) is observed as a dissociation product of the ion complexes containing more than one metal cation and only if the lipid in the complex contains a double bond. Ag2H+ is formed as the main dissociation channel for all three of the fatty acids containing double bonds that were investigated while Cu2H+ is formed with one of the fatty acids and, although abundant, is not the dominant dissociation channel. Also. Cu(I) and Ag(I) ion complexes were observed with glycerolipids (including triacylglycerols and glycerophospholipids) containing either saturated or unsaturated fatty acid substituents. Interestingly. Ag2H+ ion is formed in a major fragmentation channel with the lipids that are able to form the complex with two metal cations (triacylglycerols and glycerophosphoglycerols), while lipids containing a fixed positive charge (glycerophospocholines) complex only with a single metal cation. The formation of Ag2H+ ion is a significant dissociation channel from the complex ion Ag-2(L-H)(+) where L = Glycerophospholipid (GP) (18:1/18:1). Cu(I) also forms complexes of two metal cations with glycerophospholipids but these do not produce Cu2H+ upon dissociation. Rather organic fragments, not containing Cu(I), are formed, perhaps due to different interactions of these metal cations with lipids resulting from the much smaller ionic radius of Cu(I) compared to Ag(I) (C).

Amateur Media : Social, Cultural and Legal Perspectives

The rise of Web 2.0 has pushed the amateur to the forefront of public discourse, public policy and media scholarship. Typically non-salaried, non-specialist and untrained in media production, amateur producers are now seen as key drivers of the creative economy. But how do the activities of citizen journalists, fan fiction writers and bedroom musicians connect with longer traditions of extra-institutional media production? This edited collection provides a much-needed interdisciplinary contextualisation of amateur media before and after Web 2.0. Surveying the institutional, economic and legal construction of the amateur media producer via a series of case studies, it features contributions from experts in the fields of law, economics and media studies based in the UK, Europe and Singapore. Each section of the book contains a detailed case study on a selected topic, followed by two further pieces providing additional analysis and commentary. Using an extraordinary array of case studies and examples, from YouTube to online games, from subtitling communities to reality TV, the book is neither a celebration of amateur production nor a denunciation of the demise of professional media industries. Rather, this book presents a critical dialogue across law and the humanities, exploring the dynamic tensions and interdependencies between amateur and professional creative production. This book will appeal to both academics and students of intellectual property and media law, as well as to scholars and students of economics, media, cultural and internet studies.

Law, ethics and pandemic preparedness : the importance of cross-jurisdictional and cross-cultural perspectives

OBJECTIVE To explore social equity, health planning, regulatory and ethical dilemmas in responding to a pandemic influenza (H5N1) outbreak, and the adequacy of protocols and standards such as the International Health Regulations (2005). APPROACH This paper analyses the role of legal and ethical considerations for pandemic preparedness, including an exploration of the relevance of cross-jurisdictional and cross-cultural perspectives in assessing the validity of goals for harmonisation of laws and policies both within and between nations. Australian and international experience is reviewed in various areas, including distribution of vaccines during a pandemic, the distribution of authority between national and local levels of government, and global and regional equity issues for poorer countries. CONCLUSION This paper finds that questions such as those of distributional justice (resource allocation) and regulatory frameworks raise important issues about the cultural and ethical acceptability of planning measures. Serious doubt is cast on a 'one size fits all' approach to international planning for managing a pandemic. It is concluded that a more nuanced approach than that contained in international guidelines may be required if an effective response is to be constructed internationally. IMPLICATIONS The paper commends the wisdom of reliance on 'soft law', international guidance that leaves plenty of room for each nation to construct its response in conformity with its own cultural and value requirements.
