Between Sound and Sight: Framing the Exotic in Roysten Abel's The Manganiyar Seduction

Roysten Abel’s The Manganiyar Seduction is perhaps the most popular performance of Indian folk music on the global festival market today. This performance of Rajasthani folk music is an apt exemplification of an auto-exoticism framed as cultural commodity. Its mise en scéne of musicians framed, literally, by illuminated red square boxes ‘theatricalises’ Rajasthan’s folk culture of orality and renders such a tradition the quality of strangeness that borders on theatre and music, contemporary and traditional. The ‘dazzling’ union of the Manganiyar’s music and scenography of Amsterdam’s red light district engendered an exotic seduction that garnered raving reviews on its global tour. This paper then examines the production’s performative interstices: the in betweenness of sound and sight where aural tradition is ‘spectacularised’, and the shifting convergences of tradition and cultural consumption. It further interrogates the role of reception in the construction of such ‘exotic’ spectacles.

A defeasible reasoning model of inductive concept learning from examples and communication

This paper introduces a logical model of inductive generalization, and specifically of the machine learning task of inductive concept learning (ICL). We argue that some inductive processes, like ICL, can be seen as a form of defeasible reasoning. We define a consequence relation characterizing which hypotheses can be induced from given sets of examples, and study its properties, showing they correspond to a rather well-behaved non-monotonic logic. We will also show that with the addition of a preference relation on inductive theories we can characterize the inductive bias of ICL algorithms. The second part of the paper shows how this logical characterization of inductive generalization can be integrated with another form of non-monotonic reasoning (argumentation), to define a model of multiagent ICL. This integration allows two or more agents to learn, in a consistent way, both from induction and from arguments used in the communication between them. We show that the inductive theories achieved by multiagent induction plus argumentation are sound, i.e. they are precisely the same as the inductive theories built by a single agent with all data. © 2012 Elsevier B.V.

Implementation and testing of Lanczos-based algorithms for Random-Phase Approximation eigenproblems

The treatment of the Random-Phase Approximation Hamiltonians, encountered in different frameworks, like time-dependent density functional theory or Bethe-Salpeter equation, is complicated by their non-Hermicity. Compared to their Hermitian Hamiltonian counterparts, computational methods for the treatment of non-Hermitian Hamiltonians are often less efficient and less stable, sometimes leading to the breakdown of the method. Recently [Gruning et al. Nano Lett. 8 (2009) 28201, we have identified that such Hamiltonians are usually pseudo-Hermitian. Exploiting this property, we have implemented an algorithm of the Lanczos type for Random-Phase Approximation Hamiltonians that benefits from the same stability and computational load as its Hermitian counterpart, and applied it to the study of the optical response of carbon nanotubes. We present here the related theoretical grounds and technical details, and study the performance of the algorithm for the calculation of the optical absorption of a molecule within the Bethe-Salpeter equation framework.

Heeding the stains: Lacan and organizational change

Purpose: The purpose of this paper is to add to current discussions on the use of Lacanian psychoanalysis in organizational change. Specifically, It argues that critiques of Lacan's work must be acknowledged and incorporated into these discussions. To date, there remains a silence surrounding these critiques within organization studies.
Design/methodology/approach: The paper presents the existing studies that draw upon Lacan's work in the context of organizational change initiatives. It highlights the value of this theory. Next, it outlines critiques of Lacan's concepts of phallus and incest taboo, and show how these concepts can be exclusionary.
Findings: The paper finds that there remains little debate within organization studies around such critiques. Lacan tends to be employed in ways that risk reproducing particular, exclusionary aspects of his theory. A homophobic and patriarchal legacy persists in appropriations of his writing. It outlines alternative ways of reading Lacan, which aim to avoid such exclusions. It shows how introducing such alternatives is a difficult project, first, given the silence surrounding critiques of Lacan in the organizational change literature. Second, following Foucault, It argues that language has power: a patriarchal schema is self-reinforcing in its persistence within a particular discipline, and thus difficult to dislodge.
Research limitations/implications: Given these findings, the paper concludes that organization theorists and practitioners ought to engage with critiques of Lacan's work, when employing it in their own. The silence surrounding such legacies is dangerous. It argues that the first step in engaging with Lacan's work should be to give voice to such critiques, if his writing is to be employed in the practice and study of organizational change.
Originality/value: This paper provides a unique engagement with Lacan's work in the context of the study and practice of organizational change interventions. It presents an evaluation of well-known critiques and useful recommendations for theorists and practitioners considering a Lacanian approach to this area of management studies. © Emerald Group Publishing Limited.

Interventions to reduce prejudice and enhance inclusion and respect for ethnic differences in early childhood: A systematic review

A systematic review was conducted of studies evaluating the effects of interventions aimed at reducing ethnic prejudice and discrimination in young children. Articles published between 1980 and 2010 and including children of 8 years and under were identified, harvested, and assessed for quality, both for the exposure/program as well as for the evaluation. In total, 32 studies (14 contact and 18 media or instruction) yielded 62 effects on attitudes and 59 effects on peer relations. An overall count of the positive (40%), non-significant (50%), and negative effects (10%) indicate a mixed picture. Overall, more attitude effects (55%) than peer relations effects (25%) were positive, and media/instruction (47%) was more successful than contact (36%). Most of the effects were observed with children from a majority ethnicity: 67% of the attitude effects were positive, and media/instruction and contact were equally effective at delivering these. Few differences were found as a function of the quality of the exposure and evaluation, but differences were found depending on the context of exposure (naturally occurring or experimental manipulation) and research design (random assignment or self-selection). In conclusion, the findings were more mixed than expected, though sufficiently strong studies exist to provide lessons for future research.

The Paradox of Performative Immediacy: Law, Music, Improvisation

In a 1999 essay, J.M. Balkin and Sanford Levinson called for law to be considered as a performing art. Against or perhaps going further than Balkin and Levinson, this commentary claims that while engagement with performance practices in the arts, such as music, is of the utmost value to law and legal theory, we must not take for granted what it means to ‘‘perform’’. Uniting Jacques Derrida’s la Villette performance (with jazz legend, Ornette Coleman) with his writings on performativity in law, this commentary looks to the musical practice of improvisation to trouble the notion of performance as immediate and singular and to question taken for granted distinctions between text and performance, writing and music, composition and improvisation. The consequence of this refined understanding of the performative on legal theory and the actual practice of law is a reconceptualization of law as improvisation, that is, both singular and general, pre-existent and immediate, and a refocusing on the creativity that lies at the heart of law’s conservativism.

Intensive temperature and quantum correlations for refined quantum measurements

We consider the concept of temperature in a setting beyond the standard thermodynamics prescriptions. Namely, rather than restricting to standard coarse-grained measurements, we consider observers able to master any possible quantum measurement -a scenario that might be relevant at nanoscopic scales. In this setting, we focus on quantum systems of coupled harmonic oscillators and study the question of whether the temperature is an intensive quantity, in the sense that a block of a thermal state can be approximated by an effective thermal state at the same temperature as the whole system. Using the quantum fidelity as figure of merit, we identify instances in which this approximation is not valid, as the block state and the reference thermal state are distinguishable for refined measurements. Actually, there are situations in which this distinguishability even increases with the block size. However, we also show that the two states do become less distinguishable with the block size for coarse-grained measurements -thus recovering the standard picture. We then go further and construct an effective thermal state which provides a good approximation of the block state for any observables and sizes. Finally, we point out the role that entanglement plays in this scenario by showing that, in general, the thermodynamic paradigm of local intensive temperature applies whenever entanglement is not present in the system.

Micro- and Nano-scale Tribo-Corrosion of Cast CoCrMo

Previous studies have established that some of the wear damage seen on cast CoCrMo joint surface is caused by entrained third-body hard particles. In this study, wet-cell micro-indentation and nano-scratch tests have been carried out with the direct aim of simulating wear damage induced by single abrasive particles entrained between the surfaces of cast CoCrMo hip implants. In situ electrochemical current noise measurements were uniquely performed to detect and study the wear-induced corrosion as well as the repassivation kinetics under the micro-/nano-scale tribological process. A mathematical model has been explored for the CoCrMo repassivation kinetics after surface oxide film rupture. Greater insights into the nature of the CoCrMo micro-/nano-scale wear-corrosion mechanisms and deformation processes are determined, including the identification of slip band formation, matrix/carbide deformation, nanocrystalline structure formation and strain-induced phase transformation. The electrochemical current noise provides evidence of instantaneous transient corrosion activity at the wearing surface resulting from partial oxide rupturing and stripping, concurrent with the indent/scratch.

Spectres of Shakespeare:Ong Keng Sen’s Search: Hamlet and the Intercultural Myth

Arguably, the myth of Shakespeare is a myth of universality. Much has been written about the dramatic, thematic and ‘humanistic’ transference of Shakespeare’s works: their permeability, transcendence of cultures and histories, geographies and temporalities. Located within this debate is a belief that this universality, among other dominating factors, is founded upon the power and poeticism of Shakespeare’s language. Subsequently, if we acknowledge Frank Kermode’s assertion that “the life of the plays is the language” and “the secret (of Shakespeare’s works) is in the detail,” what then becomes of this myth of universality, and how is Shakespeare’s language ‘transferred’ across cultures? In Asian intercultural adaptations, language becomes the primary site of confrontation as issues of semantic accuracy and poetic affiliation abound. Often, the language of the text is replaced with a cultural equivalent or reconceived with other languages of the stage – song and dance, movement and music; metaphor and imagery consequently find new voices. Yet if myth is, as Roland Barthes propounds, a second-order semiotic system that is predicated upon the already constituted sign, here being language, and myth is parasitical on language, what happens to the myth of Shakespeare in these cultural re-articulations? Wherein lies the ‘universality’? Or is ‘universality’ all that it is – an insubstantial (mythical) pageant? Using Ong Keng Sen’s Search Hamlet (2002), this paper would examine the transference of myth and / as language in intercultural Shakespeares. If, as Barthes argues, myths are to be understood as metalanguages that adumbrate social hegemonies, intercultural imaginings of Shakespeare can be said to expose the hollow myth of universality yet in a paradoxical double-bind reify and reinstate this self-same myth.

Excess mortality in Type 1 diabetes diagnosed in childhood and adolescence: a systematic review of population-based cohorts

Aims: Systematic review of mortality in childhood-/adolescent-diagnosed Type 1 diabetes and examination of factors explaining the mortality variation between studies. 
Methods: Relevant studies were identified from systematic searches of MEDLINE and EMBASE. Observed and expected numbers of deaths were extracted, and standardised mortality ratios (SMRs) and 95 % confidence intervals (CIs) were calculated. Negative binomial regression was used to investigate association between mortality and study/country characteristics.
Results: Thirteen relevant publications with mortality data were identified describing 23 independent studies. SMRs varied markedly ranging from 0 to 854 (chi-squared = 70.68,df = 21, p<0.0001). Significant associations were observed between SMR and mid-year of follow-up [incidence rate ratio (IRR) 0.95, 95 % CI 0.91–0.99 equivalent to a 5 % decrease per year], between SMR and infant mortality rate (IRR 1.07, 95 % CI 1.02–1.12, a 7 % increase for each death per 1,000 live births) and, after omitting an outlier, between SMR and health expenditure as a percentage of gross domestic product (GDP) (IRR 0.79, 95 % CI 0.68–0.93, a 21 % decrease for each one percent increase in GDP). No relationship was detected between SMR and a country’s childhood diabetes incidence rate or GDP.
Conclusions: Excess mortality in childhood-/adolescent diagnosed Type 1 diabetes is apparent across countries worldwide. Excesses were less marked in more recent studies and in countries with lower infant mortality and higher health expenditure.

“A quiet still voice that just touches”: music’s relevance for adults living with life-threatening cancer diagnoses.

Purpose
Music has historically aided health and loss-adaptation, however, cancer patients’ experience of music for self-care is not well understood. This study examines adult cancer patients’ views about music’s role before and after diagnosis.
Methods
Constructivist approach, with grounded theory informed design using convenience, snowball and theoretical sampling. Patients from Australian metropolitan cancer and hospice settings completed demographic questionnaires and participated in semi-structured interviews. Qualitative inter-rater reliability was applied.
Results
Fifty-two patients reported comparable time spent experiencing music pre-post diagnosis. Music may remain incidental; however, many patients adapt music usage to ameliorate cancer’s aversive effects. Patients often draw from their musical lives and explore unfamiliar music to: remain connected with pre-illness identities; strengthen capacity for enduring treatment, ongoing survival (even when knowing “you’re going to die”), or facing death; reframe upended worlds; and live enriched lives. Patients can ascribe human or physical properties to music when describing its transformative effects. Familiar lyrics maybe reinterpreted, and patients’ intensified emotional reactions to music can reflect their threatened mortality. Sometimes music becomes inaccessible, elusive, and/or intensifies distress and is avoided. Families’, friends’ and professionals’ recognition of patients’ altered musical lives and music-based suggestions can extend patients’ use of music for self-care.
Conclusion
Health professionals can support patients by inquiring about their music behaviours and recognising that altered music usage may signify vulnerability. Although commonly recommended, hospital concerts and music broadcasts need sensitive delivery. Patients’ preferred music should be available in diagnostic, treatment and palliative settings because it can promote endurance and life enrichment.

Kuznetsov independence for interval-valued expectations and sets of probability distributions: Properties and algorithms

Kuznetsov independence of variables X and Y means that, for any pair of bounded functions f(X) and g(Y), E[f(X)g(Y)]=E[f(X)] *times* E[g(Y)], where E[.] denotes interval-valued expectation and *times* denotes interval multiplication. We present properties of Kuznetsov independence for several variables, and connect it with other concepts of independence in the literature; in particular we show that strong extensions are always included in sets of probability distributions whose lower and upper expectations satisfy Kuznetsov independence. We introduce an algorithm that computes lower expectations subject to judgments of Kuznetsov independence by mixing column generation techniques with nonlinear programming. Finally, we define a concept of conditional Kuznetsov independence, and study its graphoid properties.

Measuring work and heat in ultracold quantum gases

We propose a feasible experimental scheme to direct measure heat and work in cold atomic setups. The method is based on a recent proposal which shows that work is a positive operator valued measure (POVM). In the present contribution, we demonstrate that the interaction between the atoms and the light polarization of a probe laser allows us to implement such POVM. In this way the work done on or extracted from the atoms after a given process is encoded in the light quadrature that can be measured with a standard homodyne detection. The protocol allows one to verify fluctuation theorems and study properties of the non-unitary dynamics of a given thermodynamic process.

Distributed Massive MIMO in Cellular Networks: Impact of Imperfect Hardware and Number of Oscillators

Distributed massive multiple-input multiple-output (MIMO) combines the array gain of coherent MIMO processing with the proximity gains of distributed antenna setups. In this paper, we analyze how transceiver hardware impairments affect the downlink with maximum ratio transmission. We derive closed-form spectral efficiencies expressions and study their asymptotic behavior as the number of the antennas increases. We prove a scaling law on the hardware quality, which reveals that massive MIMO is resilient to additive distortions, while multiplicative phase noise is a limiting factor. It is also better to have separate oscillators at each antenna than one per BS.
