Deterritorialized, multilocated and distributed: Musical space, poietic domains and cognition in distance collaboration
Authors: Pignato Joseph Michael , Begany Grace M. 
Published: November 2015

Abstract
This article presents detailed descriptions of a series of distance collaborations between two institutions of music education; the State University of New York, Oneonta, in the United States, and the Musrara Naggar School of Art in Jerusalem, Israel. The collaborations between Oneonta and Musrara encompass multiple modes of collaborative interaction, including asynchronous, interstitial and synchronized collaboration. As such the collaborations between the two institutions provide a rich case for understanding practical considerations for and implications of technologically mediated and distributed distance collaborations in music. The authors analyse the collaborations between the two institutions to demonstrate how the increasingly deterritorialized, multilocated nature of technologically mediated distance collaborations generates and encompasses multiple levels of poietic space. Those poietic spaces include micro poietic spaces representative of the individual participants, larger poetic spaces representative of co-located collaborators and contributors, and still larger macro poietic spaces that do not exist in anyone single locale but, instead, encompass the entire poietic sphere of such collaborations. To further understand the dynamics of technologically mediated distance collaboration, the authors introduce an emerging model for understanding such collaborations. That model draws on the philosophical concept of poiesis and on distributed cognition theory, framework drawn from the field of human–computer interaction (HCI).
DAW democracy? The dearth of diversity in ‘Playing the Studio’
Authors: Bell Adam Patrick 
Published: November 2015

Abstract
In theory anyone with a computer, tablet, or smartphone can ‘play the studio’, but is this reality or rhetoric? The putative democratization of recording technology is tethered to a basic economic argument – affordability equals access – while analyses of the sociocultural conditions of this mode of music making have been largely overlooked. Considering that playing the studio is an elemental practice in the making of many popular musics, the implications of this inquiry are relevant to all dwellers on the delta of where music, technology and education meet. First, I provide a concise history of the concept of playing the studio to frame the subsequent discussion on diversity in this practice, particularly as it relates to gender. Second, I report findings from a survey I conducted in New York City on playing the studio, which confirm this practice is predominantly the preserve of white, male guitarists. The dearth of women in the sample (11%) serves to elucidate the reality that the supposed ‘democratization’ of music making ushered in by the DAW has not actually occurred. Third, I contextualize these findings with a discussion on related research to affirm that the underrepresentation of women in playing the studio is consistent with the history of recording studio culture, and more broadly with Bourdieu’s notion of ‘masculine domination’ (2001). In conclusion, I suggest that in order to de-gender the masculine/feminine binary implicit in software and hardware for music production, educators and students alike need to infiltrate the design process and be active agents in the development of the technologies they will use to make music.
Reframing popular music composition as performance-centred practice
Authors: Moir Zack , Medbøe Haftor 
Published: November 2015

Abstract
This article reports on a qualitative study of four undergraduate students specializing in popular music composition, and examines links and overlaps between three related areas: participants’ interpretations and definitions of the term ‘composition’; their use of music technology; and how they describe their professional identities and roles in the creation of popular music. Findings suggest that the concept and practice of popular music composition are intrinsically tied to music production and the creation of a sonic product or artefact. Participants describe their roles in the creation of their music as multifarious, and report that usage of music technology involves them simultaneously engaging in activities associated with music composition, engineering, production and, especially, performance. Consequently, the authors (both lecturers in popular music composition) suggest that teaching, learning and assessment in this area of popular music education should be based on understanding popular music composition as performance-centred practice.
Technologized and autonomized vocals in contemporary popular musics
Authors: Hughes Diane 
Published: November 2015

Abstract
The application of technologies to the popular singing voice has enabled it to be conveyed in a myriad of contexts. In many ways, it is the use of technology (e.g. reinforced sound, broadcasting) that has allowed the development of contemporary singing to be more aligned to modes of speech than to the vociferous tone of vaudeville performers or to the resonant classical singing voice. The contemporary singing voice became more intimate. Technology has also enabled extended audibility of the singing voice. It allows for the singing voice to be placed within a spatial context and resultant aesthetic. This article discusses further advances in technologies (specifically looping) that allow contemporary singers to record, playback and layer in real time. Whereas a range of technologies extend the contemporary singing voice (e.g. amplification), looping technologies transform vocal capabilities so that a multiplicity of creativities and colours are simultaneously evident. The discussion distinguishes between technologized and autonomized singing. It does so on the basis that the use of looping technologies for contemporary singers facilitates a high level of autonomy (vocal and musical) in performance. The discussion outlines implemented strategies for the inclusion of looping in vocal studies at tertiary level and concludes with teacher perceptions that provide insight into the ways in which reflection, vocal development and looping foster understanding and development of the singing voice and musicality more broadly.
A quest for the perfect tone: Luthiering, pedal boards and curriculum expansion
Authors: Randles Clint 
Published: November 2015

Abstract
In this article the author explores what making guitars (luthiering), designing and assembling pedal boards, and performing as a guitarist has meant for his perspective on curricular expansion in music teacher education in the United States. He provides examples of the creative process of selecting materials, exploring novel components, and establishing finishing procedures in guitar making as a means of illustrating a theory of change in music education (Randles, 2013a). Adaptive and innovative change is viewed through the practical work of both the luthier and music education curriculum reformer. Implications for the future of music education curriculum development are provided.
Exploring the experiences, perceptions and reflections of popular electronic musicians at UK higher education institutions
Authors: Thompson Paul , Alex Stevenson 
Published: November 2015

Abstract
Although formal educational institutions in the UK, and particularly in Higher Education (HE), have begun to include aspects of dance music and hip-hop styles of music in their curricula, there is still a notable lack of research into the relationship between popular electronic music-making practices, such as performance, and formal education. This study explores some of the experiences, perceptions and reflections of popular electronic musicians in formal educational institutions in the UK with a specific focus on the performance of popular electronic music. Our findings show that formal education has had some impact on the development of popular electronic musicians’ practice and, in some cases, acted as an introduction to popular electronic styles of music. However, the study’s findings also highlight the need to develop more comprehensive musical curricula that include popular electronic styles of music as well as the more established popular musical styles such as rock.
Nature connections: Cultural heritage, identity and wellbeing in Vancouver, Canada
Authors: Oddey Alison 
Published: November 2015

Abstract
I came to Vancouver, Canada in March 2014 to give a paper on ‘The Cultural Value of the Arts for Health and Well-Being’ at the 4th International Conference on Health, Wellness & Society: Holistic Health 1 at British Columbia University. I knew absolutely nothing about the First Nations people, their arts, culture and history, and how this relates to a Canadian identity. What I know now is that the cultural identity of many of these peoples is linked to their language, and that of the remaining thirty-two indigenous languages in British Columbia, some are near extinction. For these peoples, their language is their way of being and who they are. It is encouraging to learn that projects which promote language revitalization create the opportunity for cultural well-being, through the cultural connections via the traditional values embedded within each indigenous language. In the same way that we know that Western medicine treats the body, not the person, the First Nations peoples’ loss of language is holistically integrated into the whole of their history of colonization, beliefs, medicine, spiritual and cultural practices. Their cultural heritage is interwo-ven to their wellbeing.
Lord of the Rings – the Musical as a world musical product or just a British export?
Authors: White Christine 
Published: November 2015

Abstract
The stage musical adaptation of J.R.R. Tolkien’s The Lord of the Rings, began in Toronto, Canada in 2006 and then transferred to London ending its run there in 2008. It is due to embark on a new world tour in 2015.
Matthew Warchus, British theatre director created an extravagant, three-act stage production which received its premiere at Toronto’s Princess of Wales Theatre in March 2007. The production designed by Rob Howell, premiered in London in May 2007 at the Theatre Royal, Drury Lane and ended its run after 492 performances in July 2008.
The musical was the first stage adaptation of the literary epic and followed the hugely successful film trilogy. A new tour, is being designed to accommodate theatres around the globe, and will launch in New Zealand in 2015 and although the countries of the tour have not been announced, there is much interest amongst Tolkien fans for its come back. The new touring version is billed as retaining the unique, thrilling and spectacular theatrical magic of the original production. The music is by Academy Award winner A.R. Rahman (Slumdog Millionaire), Värttinä and Christopher Nightingale. The lyrics and libretto are by Shaun McKenna and Matthew Warchus. The Lord of the Rings – the Musical has lighting by Paul Pyant, special effects by Greg Meeh, sound by Simon Baker and magic illusions by Paul Kieve.
This article reviews the work as commercial product, revival or just colonial export of British or Canadian scenic motifs and stagings.
The production began in Canada and reviews wavered between praise and defamation, between a spectacular production of sets and a celebrated new musical score. The link beneath is for the reader to get a sense of the production style and values, if you haven’t seen the musical, yet.

Synergistic health effects between chemical pollutants and electromagnetic fields
Authors: Ledoigt Gérard , Sta Chaima , Goujon Eric , Souguir Dalila , El Ferjani Ezzeddine 
Published: November 2015

AbstractHumans and ecosystems are exposed to highly variable and unknown cocktail of chemicals and radiations. Although individual chemicals are typically present at low concentrations, they can interact with each other resulting in additive or potentially synergistic mixture effects. This was also observed with products obtained by radiation actions such as sunlight or electromagnetic fields that can change the effects of chemicals, such as pesticides, and metal trace elements on health. Concomitant presence of various pesticides and their transformation products adds further complexity to chemical risk assessment since chronic inflammation is a key step for cancer promotion. Degradation of a parent molecule can produce several by-products which can trigger various toxic effects with different impacts on health and environment. For instance, the cocktail of sunlight irradiated sulcotrione pesticide has a greater cytotoxicity and genotoxicity than parent molecule, sulcotrione, and questions about the impact of photochemical process on environment. Adjuvants were shown to modify the biological features of pesticides. Addition of other elements, metals or biological products, can differently enhance cell toxicity of pesticides or electromagnetic radiations suggesting a synergy in living organisms. Electromagnetic fields spreading, pesticide by-products and mixtures monitoring become greater for environmental contamination evaluations.
Testing for Ancient Selection Using Cross-population Allele Frequency Differentiation
Authors: Racimo Fernando 
Published: November 2015

Abstract
A powerful way to detect selection in a population is by modeling local allele frequency changes in a particular region of the genome under scenarios of selection and neutrality and finding which model is most compatible with the data. A previous method based on a cross-population composite likelihood ratio (XP-CLR) uses an outgroup population to detect departures from neutrality that could be compatible with hard or soft sweeps, at linked sites near a beneficial allele. However, this method is most sensitive to recent selection and may miss selective events that happened a long time ago. To overcome this, we developed an extension of XP-CLR that jointly models the behavior of a selected allele in a three-population tree. Our method - called “3-population composite likelihood ratio” (3P-CLR) - outperforms XP-CLR when testing for selection that occurred before two populations split from each other and can distinguish between those events and events that occurred specifically in each of the populations after the split. We applied our new test to population genomic data from the 1000 Genomes Project, to search for selective sweeps that occurred before the split of Yoruba and Eurasians, but after their split from Neanderthals, and that could have led to the spread of modern-human-specific phenotypes. We also searched for sweep events that occurred in East Asians, Europeans, and the ancestors of both populations, after their split from Yoruba. In both cases, we are able to confirm a number of regions identified by previous methods and find several new candidates for selection in recent and ancient times. For some of these, we also find suggestive functional mutations that may have driven the selective events.
Stochastic Resonance Effects on Apnea, Bradycardia, and Oxygenation: A Randomized Controlled Trial
Authors: Smith Vincent C. , Kelty-Stephen Damian , Qureshi Ahmad Mona , Mao Wenyang , Cakert Kelly , Osborne John , Paydarfar David 
Published: November 2015

OBJECTIVE:
To evaluate the effect of stochastic resonance (SR) stimulation on preterm infant oxygen desaturation, bradycardia, and apnea events. We hypothesized that SR stimulation will reduce these events.

METHODS:
This was a randomized crossover study conducted from April 2012 to July 2014. Eligible preterm infants were not receiving ventilation support and had at least 1 clinically documented apnea, bradycardia, and/or oxygen desaturation event. The 3 outcome variables were as follows: oxygen desaturation, bradycardia, and apnea events. Infants received up to two 3- or 4-hour intervention periods of 30-minute alternating intervals of SR stimulation and no SR stimulation. The first intervention period was randomly assigned to begin with SR stimulation either on or off, whereas the next intervention period automatically began with the opposite on/off state. We compared the SR stimulation “on” periods with the SR stimulation “off” periods with each infant serving as his or her own control.

RESULTS:
The sample consisted of 36 infants with a mean (±SD) gestational age of 30.5 ± 3 weeks and a birth weight of 1409 ± 450 g. SR stimulation decreased the number of apneic events by 50%. SR stimulation ameliorated every aspect of clinically significant oxygen desaturation events, with a 20% to 35% decrease in the number, duration, and intensity of oxygen desaturation events when SR stimulation was on. Also, SR stimulation produced a nearly 20% reduction in the intensity of bradycardia events.

CONCLUSIONS:
SR stimulation may be a noninvasive and nonpharmacologic treatment option for apnea, oxygen desaturation, and some aspects of bradycardia in premature infants.
Lack of Understanding of Cervical Cancer and Screening Is the Leading Barrier to Screening Uptake in Women at Midlife in Bangladesh: Population-Based Cross-Sectional Survey
Authors: Islam Rakibul M. , Bell Robin J. , Billah Baki , Hossain Mohammad B. , Davis Susan R. 
Published: November 2015

Abstract

Background.
Cervical cancer (CCa) is the second most common cancer among women in Bangladesh. The uptake of CCa screening was less than 10% in areas where screening has been offered, so we investigated the awareness of CCa and CCa screening, and factors associated with women's preparedness to be screened.

Methods.
A nationally representative, cross-sectional survey of women aged 30–59 years was conducted in 7 districts of the 7 divisions in Bangladesh, using a multistage cluster sampling technique. Factors associated with the awareness of CCa and screening uptake were investigated separately, using multivariable logistic regression.

Results.
On systematic questioning, 81.3% and 48.6% of the 1,590 participants, whose mean age was 42.3 (±8.0) years, had ever heard of CCa and CCa screening, respectively. Having heard of CCa was associated with living in a rural area (adjusted odds ratio [OR]: 0.42; 95% confidence interval [CI]: 0.26–0.67), being 40–49 years old (OR: 1.59; 95% CI: 1.15–2.0), having no education (OR: 0.25; 95% CI: 0.16–0.38), and being obese (OR: 2.04; 95% CI: 1.23–3.36). Of the 773 women who had ever heard of CCa screening, 86% reported that they had not been screened because they had no symptoms and 37% did not know screening was needed. Only 8.3% had ever been screened. Having been screened was associated with being 40–49 years old (OR: 2.17; 95% CI: 1.19–3.94) and employed outside the home (OR: 3.83; 95% CI: 1.65–8.9), and inversely associated with rural dwelling (OR: 0.54; 95% CI: 0.30–0.98) and having no education (OR: 0.29; 95% CI: 0.10–0.85).

Conclusion.
Lack of awareness of CCa and of understanding of the concept of screening are the key barriers to screening uptake in women at midlife in Bangladesh. Targeted educational health programs are needed to increase screening in Bangladesh with the view to reducing mortality.
Uso da densidade para estimar o teor de tântalo columbita-tantalita: aplicação ao pegmatito Ubaeira, Currais Novos (RN)
Authors: Souza Neto João Adauto de , Costa Carlos Eduardo Fernandes de Souza 
Published: November 2015

As aplicações do tântalo (Ta) estão aumentando, provocando uma procura intensa por este metal. A tantalita [(Fe,Mn)Ta2 O6 ], uma das principais fontes de Ta, ocorre como columbita-tantalita [(Fe,Mn)(Nb,Ta)2 O6 ] nos pegmatitos da Província Pegmatítica do Seridó (RN-PB). O preço deste último mineral é função do teor de Ta, o que torna imprescindível a determinação exata do conteúdo desse metal. Neste trabalho, a densidade é aplicada como um método prático e barato para se determinar o teor de Ta na columbita-tantalita. A série da columbita-tantalita é uma solução-sólida envolvendo a substituição mútua de Nb e Ta, e de Fe e Mn. Nesta série a densidade é aproximadamente proporcional ao teor de Ta, sendo portanto possível obter o teor desse metal utilizando-se a densidade. A densidade foi obtida pelas técnicas do volume deslocado e picnômetro. Pela primeira técnica obteve-se valores de densidade variando de 5,2 a 7,0 g/cm3, enquanto que pela técnica do picnômetro, estes valores variaram de 5,53 a 5,79 g/cm3. A técnica do picnômetro, considerada mais precisa, foi utilizada para determinar os teores de Ta variando entre 8,62 e 15,41 % (10,52-18,81 % de Ta2 O5) nas amostras testadas. A utilização da densidade para o fim exposto revela boas perspectivas de aplicação, uma vez que a mesma contornaria problemas de custo e dificuldades analíticas ligados às análises químicas do Ta. O uso da densidade torna-se viável considerando-se sua praticidade e baixo custo, pois utiliza materiais analíticos de uso simples e baratos, permitindo a determinação do Ta no próprio garimpo e promovendo uma rápida avaliação do minério.
Novos dados geológicos da região entre Timbaúba e Macaparana, terreno Rio Capibaribe, Província Borborema: faixa de rochas metavulcanossedimentares, corpos lenticulares de granitóides e enriquecimento anômalo em epidotos

Regionalmente a área deste estudo encontra-se inserida no contexto da "Zona Transversal", no Terreno Rio Capibaribe, e onde ocorrem as rochas do Complexo Gnáissico-Migmatítico, rochas metavulcanossedimentares, além de rochas de Suítes Magmáticas Neoproterozoicas. Visando o mapeamento geológico de semi-detalhe (escala de 1:50.000), foram realizadas as caracterizações dos principais tipos litológicos da região, com análises petrográficas detalhadas dos mesmos, entendimento das relações de campo e temporal entre as rochas, além do enquadramento das fases tectono-metamórficas que afetaram a área. Como resultado foram individualizadas quatro unidades litoestratigráficas (Complexo gnáissico-migmatítico; Complexo Metavulcanossedimentar; Granito Tipo Serra do Mascarenhas, e Granito Tipo Timbaúba). Estas duas últimas unidades correspondem às Suítes Magmáticas Neoproterozoica, e ocorrem dispostas de acordo com a influência das zonas de cisalhamento contracionais (denominadas de Pindoba e Uruçu, Fase deformacional Dn) transcorrentes (Fase Dn+1), presentes principalmente nas porções sudoeste e sudeste da área investigada. As condições de pico metamórfico são na fácies anfibolito alto (500°C < T < 650°C e 3 kbar < P < 11,5 kbar), que atingem localmente a fácies granulito (750°C), sendo atribuídas ao momento de atuação do evento deformacional Dn. E pico é sucedido por um estágio retrometamórfico na fácies xisto verde baixo (T < 350°C e 2 kbar < P < 9 kbar). Destaca-se na área estudada, a descoberta de uma faixa de rochas metavulcanossedimentares, as formas lenticulares dos corpos intrusivos (Granitos Tipo Timbaúba e Serra dos Mascarenhas), relacionados ao evento deformacional Dn (contracional), além da anômala abundância de minerais do grupo do epidoto (epidoto, alanita, zoisita/clinozoisita), notadamente nos litotipos do Granito Tipo Timbaúba.
