Low-Level Visual Processing Allows Humans to React to Animate Objects: Binding Memory as a Key Subsystem of Biological Motion Detection
Creators: name: Hamilton, Andrew
Publisher: name: Columbia Undergraduate Science Journal
Year: 2012

description: We review the literature to date on biological motion detection and its important prerequisite, human binding memory. Binding memory is the system for combining features like shape, color and size into coherent visual objects, and tracking these objects through time in short-term memory. This in turn makes possible biological motion detection, which is crucial to a wide range of human social activity. Recent experiments have shown that binding memory is available from birth, declines with old age, and is improved by emotional arousal. Furthermore, binding memory has been shown to be disturbed in neurological disorders such as autism and schizophrenia. These results promise to contribute to a greater understanding of biological motion detection in the future.

description: In recent years, it has been understood that color-ordered scattering amplitudes can be encoded as logarithmic differential forms on positive geometries. In particular, amplitudes in maximally supersymmetric Yang-Mills theory in spinor helicity space are governed by the momentum amplituhedron. Due to the group-theoretic structure underlying color decompositions, color-ordered amplitudes enjoy various identities which relate different orderings. In this paper, we show how the Kleiss-Kuijf relations arise from the geometry of the momentum amplituhedron. We also show how similar relations can be realised for the kinematic associahedron, which is the positive geometry of bi-adjoint scalar cubic theory.

The 1990s “Kutaisi Wave”: Music and Youth Movement in a Postindustrial Periphery
Creators: name: Ninoshvili, Lauren
Publisher: name: Current Musicology
Year: 2011

description: In this paper I treat popular music as a lens for exploring the intersections of place and postsocialist youth identity in Kutaisi in the early-mid 1990s, bearing in mind throughout the noticeable cultural rivalry between Kutaisi and Georgia’s political capital. Kutaisi-based musicians maintain that Georgia’s rock and alternative music industry began in their hometown in the final years of socialism and spread from there to Tbilisi. After the civil war that spoiled the initial euphoria of independence in 1991, a dynamic Kutaisi-based popular movement mobilized locally produced rock, punk rock, and related genres to publicly articulate disaffection with the conditions of postsocialism. While the dominant discourse on Kutaisi dismisses this movement as inconsequential or even a national disgrace, those who were involved consider it the first and only post-Soviet manifestation in a long genealogy of forms of liberal, cosmopolitan consciousness to emerge from Kutaisi. The latter also maintain that it marked an instance of anti-establishment grassroots social organizing, which is relatively rare in modern Georgian memory. While some participant-observers assert that the popular music produced in Kutaisi in this period was characterized by”uncompromising protest” (Gabunia 2005), I argue that the movement’s greater social significance lay in its clustering of a whole repertoire of music-centered activities to create a platform for youth-centered solidarity in the face of ubiquitous social and economic uncertainty. Many of the songs also served as vehicles for civic activism and/or resistance to authority. What were the aesthetics of difference salient to young Kutaisi musicians and their audiences in this period? How did these articulate with a local sense of place in the context of a contested national cultural geography? My study emphasizes the importance of locality within the bounds of the nation-state as a site of identity struggle in the postsocialist space.

description: This bilingual term-list is based on two previously separate lists: one for cognitive linguistics (published in Literator in 2008), and one for computational linguistics (unpublished). These lists have been revised and amalgamated, and new information fields (POS, abbreviation, primary field of usage) have been added. Terms from other fields, such as corpus linguistics, phonology, morphology, syntax, etc., have also been added. The intent is that this list will be revised, supplemented, and maintained continously, and any suggestions are therefore more than welcome.
Where a field of usage is indicated next to a term, it should merely be seen as an indication of one of the fields where it is used. Only in a few cases have inflected, derived and/or related terms been added (e.g. "attach" as a verb, and "attachment" as a noun).

description: Spectral Computed Tomography (CT) is an emerging technology that enables to estimate the concentration of basis materials within a scanned object by exploiting different photon energy spectra. In this work, we aim at efficiently solving a model-based maximum-a-posterior problem to reconstruct multi-materials images with application to spectral CT. In particular, we propose to solve a regularized optimization problem based on a plug-in image-denoising function using a randomized second order method. By approximating the Newton step using a sketching of the Hessian of the likelihood function, it is possible to reduce the complexity while retaining the complex prior structure given by the data-driven regularizer. We exploit a non-uniform block sub-sampling of the Hessian with inexact but efficient Conjugate gradient updates that require only Jacobian-vector products for denoising term. Finally, we show numerical and experimental results for spectral CT materials decomposition.

Review of Karin Bijsterveld and Jose van Dijck, eds. 2009. Sound Souvenirs: Audio Technologies, Memory and Cultural Practices. Amsterdam: Amsterdam University Press.
Creators: name: Dayal, Geeta
Publisher: name: Current Musicology
Year: 2010

description: R. Murray Schafer coined the term "sound souvenirs" in The Soundscape (1994 [1977]: 240) to describe what the editors of the eponymous book Sound Souvenirs describe as "endangered sounds, such as the sounds of pre-industrial life, that could be captured by recording technologies or stored in archives, and thus remembered after their extinction" (2009:13). Schafer himself, however, only casually mentioned the phrase in tandem with the more predominant concept of "sound marks; , the sonic equivalents oflandmarks (1977: 1 0,239). Subsequent scholarship also did not explicitly address sound souvenirs as it did other ideas from Schafer's work, such as "schizophonia;' or the splitting of a sound from its source (e.g., Feld 1994, Truax, 2001, Sterne 2006). Over 40 years later, editors Karin Bijsterveld and Jose van Dijck build on The Soundscape's lineage, as interpreted and expanded by Steven Feld (1994), Thomas Porcello (2005), and other works that foreground sound technologies as central to cultural memory; they argue in their introduction that the "sound souvenirs" lining our shelves still have yet to receive significant scholarly attention, and this book at-tempts to address that gap. Its contributors explore the cultural practices of archiving, collecting, resuscitating, and restoring past sounds in order to probe the links between sound and memory; this includes examining the ephemera surrounding recorded sound-reel-to-reel tapes, vinyl records, and so on-along with the sound-making devices themselves, old and new, from transistor radios to cassette recorders to iPods.

description: The chemical selectivity and great sensitivity of the Extended X-ray Absorption Spectroscopy technique allowed the determination, in the paramagnetic phase, of the structural distortions induced by doping in the spin-Peierls CuGeO$_3$ compound. The distorted environments were analyzed as a function of concentration, magnetic nature of impurity and the substitution site (Ni, Mn and Zn impurities on the Cu site, Si impurity on the Ge site). This has led to estimate the variation of the angles and pair distances, and hence to evaluate the magnetic coupling along the Cu chains in the vicinity of the impurities. The antiferromagnetic interaction between Cu first neighbors in the pure sample is found to be weakened around Ni, almost cancelled in the case of Mn doping, and even to change sign, producing a ferromagnetic coupling for Si doping. More generally, the structural distortions on a local scale are shown to be key parameters for the understanding of the magnetic properties of doped spin-Peierls compounds.
Statistics of Giant Radio Halos from Electron Reacceleration Models

description: The most important evidence of non-thermal phenomena in galaxy clusters comes from Giant Radio Halos (GRHs), synchrotron radio sources extended over Mpc scales, detected in a growing number of massive galaxy clusters. A promising possibility to explain these sources is given by "in situ" stochastic reacceleration of relativistic electrons by turbulence generated in the cluster volume during merger events. Cassano & Brunetti (2005) have recently shown that the expected fraction of clusters with GRHs and the increase of such a fraction with cluster mass can be reconciled with present observations provided that a fraction of 20-30 % of the turbulence in clusters is in the form of compressible modes. In this work we extend these calculations by including a scaling of the magnetic field strength with cluster mass. We show that the observed correlations between the synchrotron radio power of a sample of 17 GRHs and the X-ray properties of the hosting clusters are consistent with, and actually predicted by a magnetic field dependence on the virial mass of the form B \propto M^b, with b>0.5 and typical micro Gauss strengths of the average B intensity. The occurrence of GRHs as a function of both cluster mass and redshift is obtained. The most relevant findings are that the predicted luminosity functions of GRHs are peaked around a power P_{1.4 GHz} 10^{24} W/Hz, and severely cut-off at low radio powers due to the decrease of the electron reacceleration in smaller galaxy clusters. We expect a total number of GRHs to be discovered at ~mJy radio fluxes of ~100 at 1.4 GHz. Finally, the occurrence of GRHs and their number counts at 150 MHz are estimated in view of the fortcoming operation of low frequency observatories (LOFAR, LWA) and compared with those at higher radio frequencies.

description: We present the first detection of the near-infrared CN absorption band in the nuclear spectra of active galactic nuclei (AGN). This feature is a recent star formation tracer, being particularly strong in carbon stars. The equivalent width of the CN line correlates with that of the CO at 2.3 microns, as expected in stellar populations (SP) with ages between ~ 0.2 and ~ 2 Gyr. The presence of the 1.1 microns CN band in the spectra of the sources is taken as an unambiguous evidence of the presence of young/intermediate SP close to the central source of the AGN. Near-infrared bands can be powerful age indicators for star formation connected to AGN, the understanding of which is crucial in the context of galaxy formation and AGN feedback.

description: We provide local expressions for Chern-Weil type forms built from superconnections associated with families of Dirac operators previously investigated in work by S. Scott and later work by S. Scott and the second author. When the underlying fibration of manifolds is trivial, the even degree forms can be interpreted as renormalised Chern-Weil forms in as far as they coincide with regularised Chern-Weil forms up to residue correction terms. Similarly, a new formula for the curvature of the local fermionic vacuum line bundles is derived using a residue correction term added to the naive curvature formula. We interpret the odd degree Chern-Weil type forms built from superconnections as Wodzicki residues and establish a transgression formula along the lines of known transgression formulae for eta-forms.

description: The van der Waals dispersion coefficients of a set of polycyclic aromatic hydrocarbons, ranging in size from the single-cycle benzene to circumovalene (C66H20), are calculated with a real-time propagation approach to time-dependent density functional theory (TDDFT). In the non-retarded regime, the Casimir-Polder integral is employed to obtain C6, once the dynamic polarizabilities have been computed at imaginary frequencies with TDDFT. On the other hand, the numerical coefficient that characterizes the fully retarded regime is obtained from the static polarizabilities. This ab initio strategy has favorable scaling with the size of the system - as demonstrated by the size of the reported molecules - and can be easily extended to obtain higher order van der Waals coefficients.

description: Eruptions of coronal mass ejections (CMEs) from the Sun are usually associated with a number of signatures that can be identified in solar disc imagery. However, there are cases in which a CME that is well observed in coronagraph data is missing a clear low-coronal counterpart. These events have received attention during recent years, mainly as a result of the increased availability of multi-point observations, and are now known as 'stealth CMEs'. In this work, we analyse examples of stealth CMEs featuring various levels of ambiguity. All the selected case studies produced a large-scale CME detected by coronagraphs and were observed from at least one secondary viewpoint, enabling a priori knowledge of their approximate source region. To each event, we apply several image processing and geometric techniques with the aim to evaluate whether such methods can provide additional information compared to the study of "normal" intensity images. We are able to identify at least weak eruptive signatures for all events upon careful investigation of remote-sensing data, noting that differently processed images may be needed to properly interpret and analyse elusive observations. We also find that the effectiveness of geometric techniques strongly depends on the CME propagation direction with respect to the observers and the relative spacecraft separation. Being able to observe and therefore forecast stealth CMEs is of great importance in the context of space weather, since such events are occasionally the solar counterparts of so-called 'problem geomagnetic storms'.

description: We have studied the pressure effect on magnetostriction, both in the $ab$-plane and along the c-axis, of a (La,Pr)$_{1.2}$Sr$_{1.8}$Mn$_{2}$O$_{7}$ bilayered manganite single crystal over the temperature region where the field-induced ferromagnetic metal (FMM) transition takes place. For comparison, we have also examined the pressure dependence of magnetization curves at the corresponding temperatures. The applied pressure reduces the critical field of the FMM transition and it enhances the remanent magnetostriction. An anomalous pressure effect on the remanent lattice relaxation is observed and is similar to the pressure effect on the remanent magnetization along the c-axis. These findings are understood from the view point that the double-exchange interaction driven FMM state is strengthened by application of pressure.

description: Abstract

Our study, which covered the years 2006 to 2021, aimed to create "autoregressive vectors" to investigate the interrelationships between Work Stress, Freedom of Choice, Healthy Life, Life Ladder, and Social Support in Indonesia. We used data from the World Happiness Report and conducted an analysis to explore the correlation between these variables. Our results showed that Social Support and Healthy Life are critical factors that could affect an individual's work stress level. As social support increases, an individual may experience less work stress, and similarly, improving healthy life may reduce work stress. We also found a negative correlation between Life Ladder and Social Support as well as Healthy Life, which may suggest that individuals with lower well-being may be more prone to work stress. Our study highlights the importance of policymakers and stakeholders considering these findings when developing policies and interventions to improve the well-being of individuals and communities in Indonesia. Strategies to enhance Social Support and Healthy Life should prioritize promoting access to social and healthcare services, as well as community engagement, social cohesion, and healthy lifestyle choices. Our research underscores the need for further investigation into the complex interplay between these variables and their underlying causes to inform evidence-based policymaking.
A study of X and gamma rays following muon capture in 28Si

description: Negative muons produced via the backward decay of pions in the M9b beam channel at TRIUMF were stopped in a ²⁸Si target. The energies of the muonic X-rays and nuclear γ-rays following the muon capture were measured in order to identify a Doppler broadened γ ray line in ²⁸A1 which is suitable for analysis in terms of a γ — ν angular correlation to determine a value for the induced-pseudoscalar coupling constant (gp ). The muon beam was also stopped in 6 other background targets ( polythene, A1, stainless steel, Cu, Pb and BGO ) and their X- and γ-ray energies have been studied so as to fully understand the backgrounds associated with such a transition.
Identifying serum-inducible sequence elements on the mouse ZFP36 promoter

Year: 2011

description: Zinc finger protein 36 (ZFP36) is an RNA-binding protein that downregulates the translation of certain gene products by inducing the degradation of mRNA. ZFP36 is an immediate-early gene: its transcription is activated directly following appropriate cellular stimuli, without any need for intervening protein synthesis. Prominent mRNA targets of ZFP36 are tumor necrosis factor (TNF), epidermal growth factor (EGF) and c-fos. As defects in the c-fos and EGF pathways have been consistently found in cancers, ZFP36 is thought to be a tumor-suppressor. ZFP36 also is responsible for the suppression of TNF, giving it an additional role in the control of the inflammatory immune response. Thus, studying the regulation and action of ZPF36 may yield insights into mechanisms underlying cancer and inflammatory syndromes. To examine the regulation of ZFP36, two conserved regions upstream of the start of transcription were assayed for their ability to confer serum induction. Using a luciferase reporter gene system in HeLa cells, we show that neither region examined is induced by serum.

Identifying Factors that Control Mechanoreceptor Neuron Development in C. elegans

Year: 2012

description: Mechanosensation, or converting mechanical forces of external touch into electrical signals, is easily studied in Caenorhabditis elegans (C. elegans), a transparent nematode with a well-understood nervous system and a fully sequenced genome. The mechanosensory system mediates growth and development in most organisms; a lack of or defect in mechanosensory stimulation can lead to developmental delay in children, resulting in developmental disorders such as autism and spectrum disorders (ASDs) and Attention Deficit Disorder (ADD). Studying touch in the animal model C. elegans can elucidate the underlying neuronal mechanisms of touch and their developmental effects. In C. elegans, mechanoreceptor neurons (MRNs) detect touch, with three types that require the gene mec-3 (one of the LIM-homeodomain transcription factors) for their proper differentiation: touch receptor neurons (TRNs) (gentle touch), FLP neurons (tip of the head touch) and PVD neurons (harsh touch). While these three MRNs differentiate b the same transcription factor, each cell type’s differentiation produces distinct morphology and express different genes. FLPs exclusively express the sto-5 gene, while TRNs express the mec-17 gene. The genes that determine and distinguish FLP vs. TRN differentiation are currently limited to egl-44, egl-46 and alr-1. To identify additional genes needed for the differential expression of TRNs and FLPs, the wild-type strain (TU3813), with the FLP neurons labeled with sto-5p::gfp and the TRNs labeled with mec-17p::rfp, was mutated and animals with altered expression or neuronal morphology were isolated. While defects in both expression and morphology of the FLPs and TRNs were observed in six animals, only one animal’s mutation affecting TRN appearance was true-breeding. This morphological mutant exhibits abnormal TRN axon morphology, due to an autosomal recessive mutation. The mutant strain will be sequenced to identify the mutated gene, and the role of this gene in TRN and FLP differentiation.

description: We consider the inverse problem of designing an array of superconducting Josephson junctions that has a given maximum static current pattern as function of the applied magnetic field. Such devices are used for magnetometry and as Terahertz oscillators. The model is a 2D semilinear elliptic operator with Neuman boundary conditions so the direct problem is difficult to solve because of the multiplicity of solutions. For an array of small junctions in a passive region, the model can be reduced to a 1D linear partial differential equation with Dirac distribution sine nonlinearities. For small junctions and a symmetric device, the maximum current is the absolute value of a cosine Fourier series whose coefficients (resp. frequencies) are proportional to the areas (resp. the positions) of the junctions. The inverse problem is solved by inverse cosine Fourier transform after choosing the area of the central junction. We show several examples using combinations of simple three junction circuits. These new devices could then be tailored to meet specific applications.

We seek parameter values at which both the chiral symmetry breaking residual mass due to the finite lattice extent in the fifth dimension and the Monte Carlo time history for topological charge are acceptable for this set of quark masses at lattice spacings above 0.1 fm. We find that the Iwasaki gauge action is best, demonstrating the feasibility of using QCDOC to generate ensembles which are good representations of the QCD path integral on lattices of up to 3 fm in spatial extent with lattice spacings in the range 0.09-0.13 fm. Despite large residual masses and a limited number of sea quark mass values with which to perform chiral extrapolations, our results for light hadronic physics scale and agree with experimental measurements within our statistical uncertainties.

description: We have studied the wave dynamics and the Hawking radiation for the scalar field as well as the brane-localized gravitational field in the background of the braneworld black hole with tidal charge containing information of the extra dimension. Comparing with the four-dimensional black holes, we have observed the signature of the tidal charge which presents the signals of the extra dimension both in the wave dynamics and the Hawking radiation.

description: In this proposition, we present a link management technique for pro-active routing protocols for ad-hoc networks. This new mechanism is based on signal strength hence cross layer approach is used. The hysteresis mechanism provided by OLSR is improved upon by using signal strength in combination with the hello loss based hysteresis. The signal power is used to determine if the link-quality is improving or deteriorating while packet losses are handled through the hysteresis mechanism specified in OLSR RFC. This not only makes the link management more robust but also helps in anticipating link breakages thereby greatly improving the performance.

description: In developing the global Quantum Internet, quantum communication with low-Earth-orbit satellites will play a pivotal role. Such communication will need to be two way: effective not only in the satellite-to-ground (downlink) channel but also in the ground-to-satellite channel (uplink). Given that losses on this latter channel are significantly larger relative to the former, techniques that can exploit the superior downlink to enhance quantum communication in the uplink should be explored. In this work we do just that - exploring how continuous variable entanglement in the form of two-mode squeezed vacuum (TMSV) states can be used to significantly enhance the fidelity of ground-to-satellite quantum-state transfer relative to direct uplink-transfer. More specifically, through detailed phase-screen simulations of beam evolution through turbulent atmospheres in both the downlink and uplink channels, we demonstrate how a TMSV teleportation channel created by the satellite can be used to dramatically improve the fidelity of uplink coherent-state transfer relative to direct transfer. We then show how this, in turn, leads to the uplink-transmission of a higher alphabet of coherent states. Additionally, we show how non-Gaussian operations acting on the received component of the TMSV state at the ground station can lead to even further enhancement. Since TMSV states can be readily produced in situ on a satellite platform and form a reliable teleportation channel for most quantum states, our work suggests future satellites forming part of the emerging Quantum Internet should be designed with uplink-communication via TMSV teleportation in mind.

Investigation of planar arrays of superheated superconducting spheres
Creators: name: Meagher, Gail Aileen
Publisher: name: University of British Columbia
Year: 2010

description: The Planar Array of Superheated Spheres (PASS) has been put forward as a possible neutrino and dark matter detector. This work has concentrated on the characteristics of a 100x100 array of spheres, of indium or tin. The superheated-supercooled hysteresis curves, for magnetic fields ranging from the earth's to 16 mT, have been measured in a pumped ⁴He cryostat using an RF-SQUID readout system. Individual superconducting to normal grain flips were recorded with the indium sample due to exposure to 60 keV gammas. The effect of gravity on the shape and structure of the spheres was tested by remelting arrays in a microgravity environment. The hysteresis curves obtained for these arrays showed a decreased transition width, i.e. the temperature difference from where all the spheres are superconducting to where they are all normal.
A Subaru/Suprime-Cam wide-field survey of globular cluster populations around M87 - I: Observation, data analysis, and luminosity function

description: In this paper and a companion paper, we report on a wide-field imaging survey of the globular cluster (GC) populations around M87 carried out with Suprime-Cam on the 8.2m Subaru telescope. Here we describe the observations, data reduction, and data analysis and present luminosity functions of GC populations around M87 and NGC 4552, another luminous Virgo elliptical in our survey field. The imaging data were taken in the B, V, and I bands with a sky coverage out to 0.5 Mpc from the M87 centre. GC candidates were selected by applying a colour criterion on the B-V and V-I diagram to unresolved objects, which greatly reduces contamination. The data from control fields taken with Subaru/Suprime-Cam were also analyzed for subtraction of contamination in the GC sample. We investigate GC luminosity functions (GCLFs) within 10' (~ 45 kpc) from the host galaxy centre in detail. The V-band turnover magnitude (V_TO) is estimated to be 23.62 +-0.06 mag and 23.56 +- 0.20 mag for the GC population in M87 and NGC 4552, respectively. The GCLF is found to be a function of GC colour; V_TO of the red GC subpopulation (V-I > 1.1) is fainter than that of the blue GC subpopulation (V-I < 1.1) in both M87 and NGC 4552, as expected if the colour differences are primarily due to a metallicity effect and the mass functions of the two subpopulations are similar. The radial dependence of the GCLF is also investigated for the GC population in M87. The GCLF of each subpopulation at 1' < R < 5' is compared with that at 5' < R < 10' but no significant trend with distance is found in the shape of the GCLF. We also estimate GC specific frequencies (S_N) for M87 and NGC 4552. The S_N of the M87 GC population is estimated to be 12.5 +- 0.8 within 25'. The S_N value of the NGC 4552 GC population is estimated to be 5.0 +- 0.6 within 10'.

description: Non-Gaussian statistics of large-scale fields are routinely observed in data from atmospheric and oceanic campaigns and global models. Recent direct numerical simulations (DNSs) showed that large-scale intermittency in stably stratified flows is due to the emergence of sporadic, extreme events in the form of bursts in the vertical velocity and the temperature. This phenomenon results from the interplay between waves and turbulent motions, affecting mixing. We provide evidence of the enhancement of the classical small-scale (or internal) intermittency due to the emergence of large-scale drafts, connecting large- and small-scale bursts. To this aim we analyze a large set of DNSs of the stably stratified Boussinesq equations over a wide range of values of the Froude number ($Fr\approx 0.01-1$). The variation of the buoyancy field kurtosis with $Fr$ is similar to (though with smaller values than) the kurtosis of the vertical velocity, both showing a non-monotonic trend. We present a mechanism for the generation of extreme vertical drafts and vorticity enhancements which follows from the exact equations for field gradients.

From the Center in the Middle: Working Tambura Bands and the Construction of the In Between in Croatia and its Intimates
Creators: name: MacMillen, Ian
Publisher: name: Current Musicology
Year: 2011

description: In November 2009, Croatian pop singer Miroslav Škoro performed in front of some twenty thousand fans at Arena Zagreb, the capital city’s much lauded new sports hall. This was the second largest audience drawn by a Croatian act since the hall’s opening the previous December, I a testament to Škoro’s continuing status as one of Croatia’s most popular patriotic performers (as well as television star and, in recent years, politician and record mogul). Aside from the notably large attendance, the concert in Zagreb was of particular significance to Škoro for its timing: held on the twentieth day of November, his performance celebrated twenty years’ work in the music industry as a professional singer and songwriter. Accompanied by his band (on backup vocals, tenor saxophone, acoustic and electric guitars, keyboard, drums, and electric bass) and a number of guest musicians from past projects and from his family, Škoro performed repertoire from throughout his career and thereby commemorated his twenty years of hit songs and his many musical collaborations with these and other musicians. In this article, I examine recent economic strategies and difficulties of Croatia-based semiprofessional tambura bands in light of their relations with musical celebrities such as Skoro and with Croat fans in both domestic and international contexts. Drawing on fieldwork conducted with numerous bands at rehearsals and concerts between 2007 and 2011, I situate their present endeavors and concerns in a deeper historical context, focusing especially on musical trends and economic changes (and their continuing role in musicians’ discourses on the state) since Croatia’s secession from the Socialist Federal Republic of Yugoslavia in 1991.5 I argue that the circulation of tambura music and mobility of ensembles in foreign extensions of the Croatian tambura scene have become integral to the current social positioning of Croatia as both occupying an economically and culturally intermediary position (in relation to its more “Balkan” and “European” neighbors) and constituting a musical center (related constructs that I explicate below). I further analyze the commercial limitations that working tambura bands face in establishing their music within Croatian popular culture and examine the impact of these conditions on the construction of a Croatian tambura “sound.”
