Rituals of creativity: tradition, modernity, and the "acoustic unconscious" in a U.S. collegiate jazz music program

In this article, I seek to complicate the distinction between imitation and creativity, which has played a dominant role in the modern imaginary and anthropological theory. I focus on a U.S. collegiate jazz music program, in which jazz educators use advanced sound technologies to reestablish immersive interaction with the sounds of past jazz masters against the backdrop of the disappearance of performance venues for jazz. I analyze a key pedagogical practice in the course of which students produce precise replications of the recorded improvisations of past jazz masters and then play them in synchrony with the recordings. Through such synchronous iconization, students inhabit and reenact the creativity epitomized by these recordings. I argue that such a practice, which I call a “ritual of creativity,” suggests a coconstitutive relationship between imitation and creativity, which has intensified under modernity because of the availability of new technologies of digital reproduction.     

Homeostatic plasticity and excitation-inhibition balance: The good,the bad,and the ugly

In this review, we discuss the significance of the synaptic excitation/inhibition (E/I) balance in the context of homeostatic plasticity, whose primary goal is thought to maintain neuronal firing rates at a set point. We first provide an overview of the processes through which patterned input activity drives synaptic E/I tuning and maturation of circuits during development. Next, we emphasize the importance of the E/I balance at the synaptic level (homeostatic control of message reception) as a means to achieve the goal (homeostatic control of information transmission) at the network level and consider how compromised homeostatic plasticity associated with neurological diseases leads to hyperactivity, network instability, and ultimately improper information processing. Lastly, we highlight several pathological conditions related to sensory deafferentation and describe how, in some cases, homeostatic compensation without appropriate sensory inputs can result in phantom perceptions.     

Labour migration,sex, and polygyny: negotiating patriarchy in Tajikistan

This paper explores ways in which matrimonial arrangements are being transformed in Tajikistan by assessing the impact of labour migration in the increase of divorces as well as polygynous unions. I argue that instead of considering polygyny simply as a reification of patriarchy, we should view it as a way for both men and women to negotiate – and sometimes even subvert – the traditional patriarchal rules that dictate the institution of marriage in Tajikistan. The study is based primarily on fieldwork conducted in northern Tajikistan in 2010 and 2011.     

Mechanics of jazz shoes and their effect on pointing in child dancers

There has been little scientific investigation of the impact of dance shoes on foot motion or dance injuries. The pointed (plantar-flexed) foot is a fundamental component of both the technical requirements and the traditional aesthetic of ballet and jazz dancing. The aims of this study were to quantify the externally observed angle of plantar flexion in various jazz shoes compared with barefoot and to compare the sagittal plane bending stiffness of the various jazz shoes. Sixteen female recreational child dancers were recruited for 3D motion analysis of active plantar flexion. The jazz shoes tested were a split-sole jazz shoe, full-sole jazz shoe, and jazz sneaker. A shoe dynamometer measured the stiffness of the jazz shoes. The shoes had a significant effect on ankle plantar flexion. All jazz shoes significantly restricted the midfoot plantar flexion angle compared with the barefoot condition. The split-sole jazz shoe demonstrated the least restriction, whereas the full-sole jazz shoe the most midfoot restriction. A small restriction in metartarsophalangeal plantar flexion and a greater restriction at the midfoot joint were demonstrated when wearing stiff jazz shoes. These restrictions will decrease the aesthetic of the pointed foot, may encourage incorrect muscle activation, and have an impact on dance performance.     

Perception of ‘Back-Channeling’ Nonverbal Feedback in Musical Duo Improvisation

In witnessing face-to-face conversation, observers perceive authentic communication according to the social contingency of nonverbal feedback cues (‘back-channeling’) by non-speaking interactors. The current study investigated the generality of this function by focusing on nonverbal communication in musical improvisation. A perceptual experiment was conducted to test whether observers can reliably identify genuine versus fake (mismatched) duos from musicians’ nonverbal cues, and how this judgement is affected by observers’ musical background and rhythm perception skill. Twenty-four musicians were recruited to perform duo improvisations, which included solo episodes, in two styles: standard jazz (where rhythm is based on a regular pulse) or free improvisation (where rhythm is non-pulsed). The improvisations were recorded using a motion capture system to generate 16 ten-second point-light displays (with audio) of the soloist and the silent non-soloing musician (‘back-channeler’). Sixteen further displays were created by splicing soloists with back-channelers from different duos. Participants (N = 60) with various musical backgrounds were asked to rate the point-light displays as either real or fake. Results indicated that participants were sensitive to the real/fake distinction in the free improvisation condition independently of musical experience. Individual differences in rhythm perception skill did not account for performance in the free condition, but were positively correlated with accuracy in the standard jazz condition. These findings suggest that the perception of back-channeling in free improvisation is not dependent on music-specific skills but is a general ability. The findings invite further study of the links between interpersonal dynamics in conversation and musical interaction.     

On NCATE Standards and Culture at Work: Conversations, Hegemony, and (Dis-)Abling Consequences

Many are unaware of the power of the NCATE standards for the accreditation of schools of education. In this article, I first trace the development of the political authority of these standards, and their imposition on hundreds of schools of education. I then focus on the discourse of these standards, particularly the emphasis on "knowledge, skills and dispositions" as personal properties to control. I conclude with a call to highlight the struggles in which all involved are engaged.     

Gender,Violence and HIV: Women's Survival in the Streets

In this article I propose that genderinequality promotes – directly or indirectly –vulnerability to HIV as a consequence of amultidimensional violence (structural, symbolicand physical) experienced by injection drugusing (IDU) women in The Mission District (SanFrancisco). Given the female subordinated positionstipulated by the street ideology, I analyzehow drug dependence afforded by precariousstrategies of subsistence places IDU womenunder multiple dangers and threats. In thissetting, unequal gender relations are part of acomplex system of transactions in the streeteconomy and a way to reduce or increase theeveryday violence. Facing multiple dangers andrisks, some women adopt a subordinatedposition, some try to negotiate the conditionsof the exchanges and the others resist theexploitation. Finally, everyday violence under conditions ofgender inequality and scarcity of resourcesimposes a logic defined by the challenge ofsurvival under the threat of immediate dangers,which transform HIV into a secondary risk.     

Social Skills as a Predictor of Postsecondary Outcomes for Individuals Who Are Deaf

Social skills function as a vehicle by which we negotiate important relationships and navigate the transition from childhood into the educational and professional experiences of early adulthood. Yet, for individuals who are deaf, access to these opportunities may vary depending on their preferred language modality, family language use, and educational contexts. Drawing upon available data in the National Longitudinal Transition Survey 2 (NLTS2) and controlling for demographic covariates, we examine the predictive role of social skills in high school on postsecondary education, employment, independent living, and self-beliefs. Parents’ ratings of social skills in their children who are deaf (from the first wave, when students were in high school) strongly positively predicted graduation from postsecondary settings up to ten years later, but did not predict employment or independent living outcomes.     

Wild justice and fair play: cooperation,forgiveness, and morality in animals

In this paper I argue that we can learn much about ‘wild justice’ and the evolutionary origins of social morality – behaving fairly – by studying social play behavior in group-living animals, and that interdisciplinary cooperation will help immensely. In our efforts to learn more about the evolution of morality we need to broaden our comparative research to include animals other than non-human primates. If one is a good Darwinian, it is premature to claim that only humans can be empathic and moral beings. By asking the question ‘What is it like to be another animal?’ we can discover rules of engagement that guide animals in their social encounters. When I study dogs, for example, I try to be a ‘dogocentrist’ and practice ‘dogomorphism.’ My major arguments center on the following ‘big’ questions: Can animals be moral beings or do they merely act as if they are? What are the evolutionary roots of cooperation, fairness, trust, forgiveness, and morality? What do animals do when they engage in social play? How do animals negotiate agreements to cooperate, to forgive, to behave fairly, to develop trust? Can animals forgive? Why cooperate and play fairly? Why did play evolve as it has? Does ‘being fair’ mean being more fit – do individual variations in play influence an individual's reproductive fitness, are more virtuous individuals more fit than less virtuous individuals? What is the taxonomic distribution of cognitive skills and emotional capacities necessary for individuals to be able to behave fairly, to empathize, to behave morally? Can we use information about moral behavior in animals to help us understand ourselves? I conclude that there is strong selection for cooperative fair play in which individuals establish and maintain a social contract to play because there are mutual benefits when individuals adopt this strategy and group stability may be also be fostered. Numerous mechanisms have evolved to facilitate the initiation and maintenance of social play to keep others engaged, so that agreeing to play fairly and the resulting benefits of doing so can be readily achieved. I also claim that the ability to make accurate predictions about what an individual is likely to do in a given social situation is a useful litmus test for explaining what might be happening in an individual's brain during social encounters, and that intentional or representational explanations are often important for making these predictions.     

Forensic fictions: Science,television production,and modern storytelling

This essay uses interviews with television creators, writers, and producers to examine how media practitioners utilise, negotiate and transform forensic science in the production of televisual stories including the creation of unique visuals, character exploration, narrative progression, plot complication, thematic development, and adding a sense of authenticity. Television as a medium has its own structures and conventions, including adherence to a show’s franchise, which put constraints on how stories are told. I demonstrate how television writers find forensic science to be an ideal tool in navigating television’s narrative constraints by using forensics to create conflicts, new obstacles, potential solutions, and final solutions in their stories. I show how television writers utilise forensic science to provide the scientific certainty their characters require to catch the criminal, but also how uncertainty is introduced in a story through the interpretation of the forensics by the show’s characters. I also argue that televisual storytellers maintain a flexible notion of scientific realism based on the notion of possibility that puts them at odds with scientists who take a more demanding conception of scientific accuracy based on the concept of probability.     

Characterization of novel GPCR gene coding locus in amphioxus genome: gene structure, expression, and phylogenetic analysis with implications for its involvement in chemoreception

Chemosensation is the primary sensory modality in almost all metazoans. The vertebrate olfactory receptor genes exist as tandem clusters in the genome, so that identifying their evolutionary origin would be useful for understanding the expansion of the sensory world in relation to a large-scale genomic duplication event in a lineage leading to the vertebrates. In this study, I characterized a novel GPCR (G-protein-coupled receptor) gene-coding locus from the amphioxus genome. The genomic DNA contains an intronless ORF whose deduced amino acid sequence encodes a seven-transmembrane protein with some amino acid residues characteristic of vertebrate olfactory receptors (ORs). Surveying counterparts in the Ciona intestinalis (Asidiacea, Urochordata) genome by querying BLAST programs against the Ciona genomic DNA sequence database resulted in the identification of a remotely related gene. In situ hybridization analysis labeled primary sensory neurons in the rostral epithelium of amphioxus adults. Based on these findings, together with comparison of the developmental gene expression between amphioxus and vertebrates, I postulate that chemoreceptive primary sensory neurons in the rostrum are an ancient cell population traceable at least as far back in phylogeny as the common ancestor of amphioxus and vertebrates.     

Targeted high-throughput sequencing identifies mutations in atlastin-1 as a cause of hereditary sensory neuropathy type I

Hereditary sensory neuropathy type I (HSN I) is an axonal form of autosomal-dominant hereditary motor and sensory neuropathy distinguished by prominent sensory loss that leads to painless injuries. Unrecognized, these can result in delayed wound healing and osteomyelitis, necessitating distal amputations. To elucidate the genetic basis of an HSN I subtype in a family in which mutations in the few known HSN I genes had been excluded, we employed massive parallel exon sequencing of the 14.3 Mb disease interval on chromosome 14q. We detected a missense mutation (c.1065C>A, p.Asn355Lys) in atlastin-1 (ATL1), a gene that is known to be mutated in early-onset hereditary spastic paraplegia SPG3A and that encodes the large dynamin-related GTPase atlastin-1. The mutant protein exhibited reduced GTPase activity and prominently disrupted ER network morphology when expressed in COS7 cells, strongly supporting pathogenicity. An expanded screen in 115 additional HSN I patients identified two further dominant ATL1 mutations (c.196G>C [p.Glu66Gln] and c.976 delG [p.Val326TrpfsX8]). This study highlights an unexpected major role for atlastin-1 in the function of sensory neurons and identifies HSN I and SPG3A as allelic disorders.     

Scientific discoveries as cultural displays: a further test of Miller's courtship model

The biographies of 280 scientists demonstrate that the age distribution of their career peaks is identical to those of jazz musicians, painters, and writers, and that this universal age profile holds only among scientists who were married some time in their lives. I interpret this as support for Miller's cultural display model in an evolutionarily novel environment.     

Mechanosensory-defective, male-sterile unc mutants identify a novel basal body protein required for ciliogenesis in Drosophila

uncoordinated (unc) mutants of Drosophila, which lack transduction in ciliated mechanosensory neurons, do not produce motile sperm. Both sensory and spermatogenesis defects are associated with disrupted ciliary structures: mutant sensory neurons have truncated cilia, and sensory neurons and spermatids show defects in axoneme ultrastructure. unc encodes a novel protein with coiled-coil segments and a LisH motif, which is expressed in type I sensory neurons and in the male germline - the only ciliogenic cells in the fly. A functional UNC-GFP fusion protein specifically localizes to both basal bodies in differentiating sensory neurons. In premeiotic spermatocytes it localizes to all four centrioles in early G2, remaining associated with them through meiosis and as they become the basal bodies for the elongating spermatid flagella. UNC is thus specifically required for normal ciliogenesis. Its localization is an early marker for the centriole-basal body transition, a central but enigmatic event in eukaryotic cell differentiation.     

The Agency of Welfare Workers: Negotiating Devolution, Privatization, and the Meaning of Self-Sufficiency

In this article I examine how the neoliberal agenda of downsizing the state and minimizing its role in regulating the market has shaped welfare policy and the work of welfare provision. Using a study of welfare reform in Oregon, I explore how the enactment of welfare-to-work policies positions workers to negotiate the ideological terrain of welfare reform and the conflicts that privatization and devolution generate in a social welfare context. Self-sufficiency, the professed goal of welfareto- work programs, is a complex concept, saturated with ideological meaning. Examination of the work of welfare provision provides an opportunity to analyze how workers give meaning to self-sufficiency and construct their work as positive for the families they serve. However, high caseloads, unrealistic agency expectations, and conflicting mandates bear down hard on workers, creating disenchantment with agency policy and undermining workers' ability to meet clients' needs, [welfare, ideology, work, the United States, neoliberalism]     

The Politics and Regulation of Anger in Urban China

Negative emotions such as anger, and community responses to their expression are culturally and politically conditioned, including by dominant medical discourse on anger’s somatic and psychic effects. In this article I examine local genres of anger expression in Beijing, China, particularly among marginalized workers, and address culturally specific responses to them. Through majie (rant), xiangpi ren (silenced rage), and nande hutu (muddledness as a more difficult kind of smartness), workers strategically employ anger to seek redress for injustices and legitimate their moral indignation while challenging official psychotherapeutic interventions. Those who seek to regulate anger, mostly psychosocial workers acting as arm’s-length agents of the state, use mixed methods that draw on Western psychotherapy and indigenous psychological resources to frame, medicalize or appease workers’ anger in the name of health and social stability. I demonstrate how the two processes—anger expression and responses to it—create tensions and result in an ambiguous and multivalent social terrain which Chinese subjects must negotiate and which the state attempts to govern. I argue that the ambivalence and multi-valence of anger expressions and state-sponsored reactions to them render this emotion both subversive vis-à-vis power and subject to manipulations that maintain social order.     

Negotiating “The Social” and Managing Tuberculosis in Georgia

In this paper I utilize anthropological insights to illuminate how health professionals and patients navigate and negotiate what for them is social about tuberculosis in order to improve treatment outcomes and support patients as human beings. I draw on ethnographic research about the implementation of the DOTS (Directly Observed Therapy, Short Course) approach in Georgia’s National Tuberculosis Program in the wake of the Soviet healthcare system. Georgia is a particularly unique context for exploring these issues given the country’s rich history of medical professionalism and the insistence that the practice of medicine is a moral commitment to society. I argue for critical attention to the ways in which treatment recipients and providers navigate what, for them, is “social” about therapeutic practices and their significance for avoiding biological and social reductionism.     

Social and River Networks for the Trees: Wounaan's Riverine Rhizomic Cosmos and Arboreal Conservation

ABSTRACT   The effects of environmental conservation and development are of significant anthropological interest. Recent focus on the politics of knowledge and translation has shown the importance of cosmology in conservation encounters. I examine how Wounaan indigenous peoples and extralocal conservation practitioners "translate" eastern Panama based on their own cosmologies. ¹ Specifically, I explore how Wounaan's social and river-networked rhizomic cosmos is overlooked in the practice of forest-focused conservation. This results from Panama's environmental history, in which actors simplified early representations of a complex landscape to one characterized by forests, as well as a Western bias toward forests with scant attention paid to cosmology. Finally, I note how Wounaan negotiate this cultural disconnect by emphasizing their ties to forests. In so doing, they buttress the arboreal bias, in turn reinforcing power relations, but also giving themselves political leverage in conservation activities. These results inform recent discussion about politics and scientific praxis in conservation.     

The Social Life of Death on Delhi's Streets: Unclaimed Souls,Pollutive Bodies,Dead Kin and the Kinless Dead

ABSTRACT

How does the status of ‘street children’ in life inflect the narrative representation of their deaths? Street-dwelling children's interactions with death in North India reveal much about how their identities are produced in public domains. In this paper, I examine several instances of ‘homeless child’ death to illuminate the place of such subjects in society and urban space, and to interrogate the degree to which they can be rendered ‘recognizable’ or ‘grievable’, in Butler's (2010) terminology. In particular, I explore the presence or absence of kin in the ways that child death is narrated. I also explore the related question of how living ‘vagabond (aawara) children’ situate their status in narratives of death and loss. I conclude with discussions of how children negotiate their orientations towards death through ghost narratives, and of the space-, economy- and age-bound assignment of pollutive tasks once reserved for low castes to street-dwelling children.     

THE BETA-BINOMIAL MODEL: ACCOUNTING FOR INTER-TRIAL VARIATION IN REPLICATED DIFFERENCE AND PREFERENCE TESTS

Binomial tests are commonly used in sensory difference and preference testing under the assumptions that choices are independent and choice probabilities do not vary from trial to trial. This paper addresses violations of the latter assumption (often referred to as overdispersion) and accounts for variation in inter-trial choice probabilities following the Beta distribution. Such variation could arise as a result of differences in test substrate from trial to trial, differences in sensory acuity among subjects or the existence of latent preference segments. In fact, it is likely that overdispersion occurs ubiquitously in product testing. Using the Binomial model for data in which there is inter-trial variation may lead to seriously misleading conclusions from a sensory difference or preference test. A simulation study in this paper based on product testing experience showed that when using a Binomial model for overdispersed Binomial data, Type I error may be 0.44 for a Binomial test specification corresponding to a level of 0.05. Underestimation of Type I error using the Binomial model may seriously undermine legal claims of product superiority in situations where overdispersion occurs. The Beta-Binomial (BB) model, an extension of the Binomial distribution, was developed to fit overdispersed Binomial data. Procedures for estimating and testing the parameters as well as testing for goodness of fit are discussed. Procedures for determining sample size and for calculating estimate precision and test power based on the BB model are given. Numerical examples and simulation results are also given in the paper. The BB model should improve the validity of sensory difference and preference testing.
