Effects of high and low impact magnitudes on concussion measures in collegiate football players
Creators: name: McCaffrey, Meghan Ann
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: The purpose of this study was to investigate the effects of a theoretical concussive injury threshold on balance and neurocognitive performance in the absence of self-reported symptoms immediately following two different impact conditions (high and low) sustained in 43 Division I football players. A double-blind study utilized the Head Impact Telemetry System to classify subjects into the two testing conditions. Data were collected during the 2005 football season and 2006 spring season. Balance performance, neuropsychological functioning and self-reported symptoms were all assessed and separate repeated measures ANCOVA's were performed for each. Our data analyses resulted in significant differences for only a few of the comparisons made between the low and high magnitude conditions compared to baseline. Overall, our findings suggest that sustaining an impact greater than 100g does not result in acute observable balance and neurocognitive deficits.

description: [NiFe]-hydrogenases catalyze the reversible reaction H2 ⇄ 2H+ + 2e–. Their basic module consists of a large subunit, coordinating the NiFe(CO)(CN)2 center, and a small subunit that carries electron-transferring iron–sulfur clusters. Here, we report the in vitro assembly of fully functional [NiFe]-hydrogenase starting from the isolated large and small subunits. Activity assays complemented by spectroscopic measurements revealed a native-like hydrogenase. This approach was used to label exclusively the NiFe(CO)(CN)2 center with 57Fe, enabling a clear view of the catalytic site by means of nuclear resonance vibrational spectroscopy. This strategy paves the way for in-depth studies of [NiFe]-hydrogenase catalytic intermediates.

description: Electron-positron pair production by the Breit-Wheeler process embedded in a strong laser pulse is analyzed. The transverse momentum spectrum displays prominent peaks which are interpreted as caustics, the positions of which are accessible by the stationary phases. Examples are given for the superposition of an XFEL beam with an optical high-intensity laser beam. Such a configuration is available, e.g., at LCLS at present and at European XFEL in near future. It requires a counter propagating probe photon beam with high energy which can be generated by synchronized inverse Compton backscattering.

description: In this study, we present a new rainfall classification method based on the potential of individual rainstorm events to generate and sustain overland flow on a simplified urban model surface. Conventional rainfall classification approaches using peak intensities or rainfall sums can lead to misjudgements of the impact of rainfall events, as they do not explicitly consider the potential of rain to generate and sustain substantial amounts of overland flow on typical sealed urban surfaces. The new method of impact-based rainfall classification proposed here comprises three steps: Identification of rainfall events from high-resolution time series, computation of overland flow depths for each event, and impact-based classification of rainfall events as a function of the magnitude of overland flow. The accuracy of this approach was evaluated by its ability to describe seasonal and annual occurrences of and variations in rainstorm impacts for high-resolution series at three different urban stations in Germany.

description: Following the International Maritime Organization (IMO), in order to safeguard the realization of the Paris Agreement on climate protection, greenhouse gas (GHG) emissions have to be reduced by 50% by the year 2050. This objective shall be reached by decarbonization of maritime traffic, which is why ship operators currently increasingly search for alternative fuels. Moreover, since the start of the Ukrainian war in February 2022, this issue of alternative fuels has gained central importance in political agendas. A promising candidate for clean shipping that meets the IMO goals is ammonia since it is a carbon-free fuel. Ammonia (NH3) shows good advantages in handling and storage, and it ensures long sea voyages without any significant loss in cargo space for a reasonable price. Hence, ammonia has the potential to improve the environmental footprint of global shipping enormously. Induced by the introduction of stricter regulations in the so-called emission control areas (ECAs) in Northern Europe in 2015 as well as the renewed global sulfur cap, which entered into force in 2020, ship operators had to decide between different compliance methods, among which the most popular solutions are related to the use of expensive low-sulfur fuel oils, newbuilds and retrofits for the usage of liquefied natural gas (LNG) or the installation of scrubber technology. A change to ammonia as a marine alternative fuel represents an additional novel future option, but the successful implementation depends on the availability of NH3 in the ports, i.e., on the installation of the maritime NH3 infrastructure. Currently, the single German NH3 terminal with maritime access is located in Brunsbüttel, the western entrance to Kiel Canal. The distribution of NH3 from the existing NH3 hub to other German ports can be analyzed by the mathematical model of an inventory routing problem (IRP) that is usually solved by combinatorial optimization methods. This paper investigates the interrelated research questions, how the distribution of marine NH3 fuel can be modeled as an IRP, which distribution mode is the most economic one for the German ports and which modal mix for the NH3 supply leads to the greenest distribution. The results of this paper are empirically validated by data that were collected in several EU projects on sustainable supply chain management and green logistics. The paper includes a special section that is dedicated to the discussion of the economic turbulences related to the Ukrainian war together with their implications on maritime shipping.

description: Communication is a central component in social human–robot interaction that needs to be planned and designed prior to the actual communicative act. We therefore propose a pragmatic, linear view of communication design for social robots that corresponds to a sender–receiver perspective. Our framework is based on Lasswell’s 5Ws of mass communication: Who, says what, in which channel, to whom, with what effect. We extend and adapt this model to communication in HRI. In addition, we point out that, besides the predefined communicative acts of a robot, other characteristics, such as a robot’s morphology, can also have an impact on humans, since humans tend to assign meaning to every cue in robots’ behavior and appearance. We illustrate the application of the extended framework to three different studies on human–robot communication to demonstrate the incremental value as it supports a systematic evaluation and the identification of similarities, differences, and research gaps. The framework therefore offers the opportunity for meta-analyses of existing research and additionally draws the path for future robust research designs for studying human–robot communication.

description: Exfoliated graphitic carbon nitride (ex-g-CN) was synthesized and loaded with non-noble metals (Ni, Cu, and Co). The synthesized catalysts were tested for hydrogen production using a 300-W Xe lamp equipped with a 395 nm cutoff filter. A noncommercial double-walled quartz-glass reactor irradiated from the side was used with a 1 g/L catalyst in 20 mL of a 10 vol% triethanolamine aqueous solution. For preliminary screening, the metal-loaded ex-g-CN was synthesized using the incipient wetness impregnation method. The highest hydrogen production was observed on the Ni-loaded ex-g-CN, which was selected to assess the impact of the synthesis method on hydrogen production. Ni-loaded ex-g-CN was synthesized using different synthesis methods: incipient wetness impregnation, colloidal deposition, and precipitation deposition. The catalysts were characterized by X-ray powder diffraction, X-ray photoelectron spectroscopy, nitrogen adsorption using the Brunauer–Emmett–Teller method, and transmission electron microscopy. The Ni-loaded ex-g-CN synthesized using the colloidal method performed best with a hydrogen production rate of 43.6 µmol h−1 g−1. By contrast, the catalysts synthesized using the impregnation and precipitation methods were less active, with 28.2 and 10.1 µmol h−1 g−1, respectively. The hydrogen production performance of the suspended catalyst (440 µmol m−2 g−1) showed to be superior to that of the corresponding immobilized catalyst (236 µmol m−2 g−1).

description: The objective of this study is the investigation of nanomechanical properties using nanoindentation of extruded and heat-treated Mg-Dy-Nd-Zn-Zr, with an emphasis on the transformation of long-period stacking-ordered (LPSO) phases. Solution heat treatment was performed with different heat treatment for durations on hot extruded Mg-Dy-Nd-Zn-Zr to monitor the transformation of LPSO phases, as well as to keep track of microstructural changes. The initial fine-grained microstructure, with blocky and lamellar LPSO structures within the matrix, first transformed into coarser grains with fewer LPSO lamellae, which then increased in amount again at higher annealing duration. The blocky LPSO phases, which have the highest hardness compared to the matrix grains with and without LPSO lamellae, consistently decrease in quantity, as so does the trend in their hardness value. The Mg matrix grains with LPSO lamellae show a lower hardness compared to the Mg matrix grains without or with a just few lamellar LPSO phases, and increase in quantity at long annealing durations. The overall hardness of the microstructure is essentially determined by the LPSO lamellae-containing grains and reaches a peak at 24 h. There is another peak found for the grain size values; however, this is at later annealing duration, at 72 h. The reduction in grain size towards longer annealing durations goes along with a reactivated formation of LPSO lamellae.
Vigilans somniabar and Nec fuit nox una: a study of the dream as a narrative device in the Metamorphoses of Apuleius Madaurensis
Creators: name: Carlisle, David Paul Christian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: In the Metamorphoses of Apuleius, dreams, however bizarre, seem to have real significance for the waking world. The exact relationship of dreams to waking reality, however, is made ambiguous. Apuleius is thus able to present the most extraordinary event of all, the revelation of Isis and Lucius' conversion to her religion, in such a way that the narrative is protected from disbelief: since it is entirely directed and confirmed by a series of dreams, the possibility is left of interpreting it as a real event or as a fantasy. Two important effects result: 1) any reader's incredulity, which is inevitable, is directed towards the authority of dreams, rather than the authority of the narrator; 2) the suggestion is made that the story (especially since stories are closely related to dreams in this novel), no matter its relation to the real world, may still have real counsel for the reader.

description: The eikonal approximation for moderately small scattering amplitudes is considered. With the purpose of using for their numerical estimations, the formulas are derived which contain no Bessel functions, and, hence, no rapidly oscillating integrands. To obtain these formulas, the improper integrals of the first kind which contain products of the Bessel functions J_0(z) are studied. The expression with four functions J_0(z) is generalized. The expressions for the integrals with the product of five and six Bessel functions J_0(z) are also found. The known formula for the improper integral with two functions J_nu(z) is generalized for non-integer nu.

description: In this paper we propose an extended LOS MIMO channel model, which considers an additional phase shifting term in the transmission path, and which provides the potential to improve channel conditioning significantly. We show that this phase shifting can, for example, be achieved by adding a dielectric material between the transmitting and receiving antennas, where the phase shift is dependent on the distance the waves travel in the medium. Using that distance as a design parameter we demonstrate that the optimal spacing between antenna elements of uniform linear arrays, achieving full spatial multiplexing, can be reduced compared with the well-known spacing criterion from previous investigations.

description: Recombinant immunotoxins (RITs) are an effective class of agents for targeted therapy in cancer treatment. In this article, we demonstrate the straight-forward production and testing of an anti-CD7 RIT based on PE24 in a prokaryotic and a eukaryotic cell-free system. The prokaryotic cell-free system was derived from Escherichia coli BL21 StarTM (DE3) cells transformed with a plasmid encoding the chaperones groEL/groES. The eukaryotic cell-free system was prepared from Chinese hamster ovary (CHO) cells that leave intact endoplasmic reticulum-derived microsomes in the cell-free reaction mix from which the RIT was extracted. The investigated RIT was built by fusing an anti-CD7 single-chain variable fragment (scFv) with the toxin domain PE24, a shortened variant of Pseudomonas Exotoxin A. The RIT was produced in both cell-free systems and tested for antigen binding against CD7 and cell killing on CD7-positive Jurkat, HSB-2, and ALL-SIL cells. CD7-positive cells were effectively killed by the anti-CD7 scFv-PE24 RIT with an IC50 value of 15 pM to 40 pM for CHO and 42 pM to 156 pM for E. coli cell-free-produced RIT. CD7-negative Raji cells were unaffected by the RIT. Toxin and antibody domain alone did not show cytotoxic effects on either CD7-positive or CD7-negative cells. To our knowledge, this report describes the production of an active RIT in E. coli and CHO cell-free systems for the first time. We provide the proof-of-concept that cell-free protein synthesis allows for on-demand testing of antibody–toxin conjugate activity in a time-efficient workflow without cell lysis or purification required.

description: Waterborne viruses are a public health concern due to relatively small infection doses. Particularly, adenoviruses (AdVs) are more resistant than RNA viruses to water purification treatments in terms of ultraviolet (UV) irradiation, pH, and chlorination tolerance. Moreover, AdVs are one of the most predominant waterborne viruses. Membrane separations have proven superior removal capabilities of waterborne pathogens over other separation methods. However, virus removal at ultratrace levels is still a significant challenge for current membrane technology. This study successfully addressed this challenge by developing a bioselective polyethersulfone (PES) membrane by a joint strategy involving chitosan hydrophilic surface modification and the immobilization of adenovirus-specific molecularly imprinted nanoparticles (nanoMIPs). The topological and chemical changes taking place on the membrane surface were characterized by using atomic force microscopy (AFM) and scanning electron microscopy (SEM). Furthermore, hydrophilicity and membrane performance were investigated in terms of swelling behavior, permeation flux, and surface fouling studies. The membrane efficacy was evaluated by filtration experiments, where the virus concentration of the loading solution before filtration and the permeates after filtration was quantified. The novel bioselective membrane showed excellent virus removal capabilities by separating 99.99% of the viruses from the water samples.

description: Over the past decades, molecular dynamics (MD) simulations of biomolecules have become a mainstream biophysics technique. As the length and time scales amenable to the MD method increase, shortcomings of the empirical force fields---which have been developed and validated using relatively short simulations of small molecules---become apparent. One common artifact is aggregation of water-soluble biomolecules driven by artificially strong charge--charge interactions. Here, we report a systematic refinement of Lennard-Jones parameters (NBFIX) describing amine--carboxylate and amine--phosphate interactions, which brings MD simulations of basic peptide-mediated nucleic acids assemblies and lipid bilayer membranes in better agreement with experiment. As our refinement neither affects the existing parameterization of bonded interaction nor does it alter the solvation free energies, it improves realism of an MD simulation without introducing additional artifacts.

The cluster is confirmed to lie at $z=1.19$, and using the Combined Array for Research in Millimeter-wave Astronomy we robustly detect the Sunyaev-Zel'dovich (SZ) decrement at 13.2$σ$. The SZ data imply a mass of $\mathrm{M}_{200m}=(1.1\pm0.2)\times10^{15}$ $\mathrm{M}_\odot$, making MOO J1142+1527 the most massive galaxy cluster known at $z>1.15$ and the second most massive cluster known at $z>1$. For a standard $Λ$CDM cosmology it is further expected to be one of the $\sim 5$ most massive clusters expected to exist at $z\ge1.19$ over the entire sky. Our ongoing Spitzer program targeting $\sim1750$ additional candidate clusters will identify comparably rich galaxy clusters over the full extragalactic sky.

description: The purpose of this study was to determine if there is a difference between gender equity at institutions with a female Athletic Director (AD) compared to a male Athletic Director across Divisions I, II and III and considering football sponsorship. For the purposes of this research, gender equity is defined as proportions of participation, operating budget, recruiting budget, scholarships budget, sport sponsorship, coaching salaries and full time coaching staff allotted to women's teams. One sample t-tests comparing the means for each gender of the Athletic Director in the eight components revealed that there were significant differences between the two groups in the Participation, Sport Sponsorship, and Coaching components of gender equity. 3 X 2 ANOVAs comparing means for the institutions that sponsor football with the means of those that do not in the eight components revealed that there were significant differences in the Participation and Operating Expenses variables.

description: To understand massive star formation requires study of its initial conditions. Two massive starless core candidates, C1-N & C1-S, have been detected in IRDC G028.37+00.07 in $\rm N_2D^+$(3-2) with $ALMA$. From their line widths, either the cores are subvirial and are thus young structures on the verge of near free-fall collapse, or they are threaded by $\sim1$ mG $B$-fields that help support them in near virial equilibrium and potentially have older ages. We modeled the deuteration rate of $\rm N_2H^+$ to constrain collapse rates of the cores. First, to measure their current deuterium fraction, $D_{\rm frac}^{\rm N_2H^+}$ $\equiv [\rm N_2D^+]/[N_2H^+]$, we observed multiple transitions of $\rm N_2H^+$ and $\rm N_2D^+$ with $CARMA$, $SMA$, $JCMT$, $NRO~45m$ and $IRAM~30m$, to complement the $ALMA$ data. For both cores we derived $D_{\rm frac}^{\rm N_2H^+}\sim0.3$, several orders of magnitude above the cosmic [D]/[H] ratio. We then carried out chemodynamical modeling, exploring how collapse rate relative to free-fall, $α_{\rm ff}$, affects the level of $D_{\rm frac}^{\rm N_2H^+}$ that is achieved from a given initial condition. To reach the observed $D_{\rm frac}^{\rm N_2H^+}$, most models require slow collapse with $α_{\rm ff}\sim0.1$, i.e., $\sim1/10$th of free-fall. This makes it more likely that the cores have been able to reach a near virial equilibrium state and we predict that strong $B$-fields will eventually be detected. The methods developed here will be useful for measurement of the pre-stellar core mass function.

description: Continuous symmetries are believed to emerge at many quantum critical points in frustrated magnets. In this work, we study two candidates of this paradigm: the transverse-field frustrated Ising model (TFFIM) on the triangle and the honeycomb lattices. The former is the prototypical example of this paradigm, and the latter has recently been proposed as another realization. Our large-scale Monte Carlo simulation confirms that the quantum phase transition (QPT) in the triangle lattice TFFIM indeed hosts an emergent O(2) symmetry, but that in the honeycomb lattice TFFIM is a first-order QPT and does not have an emergent continuous symmetry. Furthermore, our analysis of the order parameter histogram reveals that such different behavior originates from the irrelevance and relevance of anisotropic terms near the QPT in the low-energy effective theory of the two models. The comparison between theoretical analysis and numerical simulation in this work paves the way for scrutinizing investigation of emergent continuous symmetry at classical and quantum phase transitions.

description: The extant literature on the mediators or mechanisms through which first-generation mindfulness-based programs (MBPs) produce change in the general population is limited and an updated review is needed. Research on possible characteristics (moderators) that may predict greater improvements in pre-post analyses of MBPs is underway but requires further clarification. In addition to pre-post analyses, there are other pathways to elucidate mediators, mechanisms, or moderators. In MBPs, there are several components or ‘active ingredients’ that can bring about change in outcomes. The mindfulness meditation practices embedded within the framework of these programs are conceptualized as key ingredients. By evaluating the mediators, mechanisms, and moderators of this core component, one can better understand the how, why, and for whom the program operates on the whole. The primary objective of this scoping review is to comprehensively investigate the how, why, and for whom mindfulness-based programs and practices work in the general population. The results from this review will help inform mindfulness teachers, researchers, and health-care professionals who intend to adapt first-generation mindfulness-based programs or practices in a unique setting or sample within the general population.

description: An investigation of nitrogen export and the potential of restoration as a tool for water quality management in catchments along an urban-rural gradient. Quantity of N exported and flow conditions dominating N export are investigated. These variables are of interest as stream restorations typically aim to increase retention under low-moderate flow. We present a metric characterizing export flow distribution, F75, and develop regressions relating F75 to development. We extrapolate F75 across a stream network to identify areas where export flow distribution is most favorable for restoration. We then examine potential to increase N retention via restoration. We develop post-restoration N export estimates for a range of uptake velocities (vf ). Results show drainage area is a dominant explanatory variable for reduction; F75 may be an important factor within drainage area. Reductions at vf comparable to other restorations were low, suggesting limited potential for water quality improvement.

description: Quantized Yang-Mills fields lie at the heart of our understanding of the strong nuclear force. To understand the theory at low energies, we must work in the strong coupling regime. The primary technique for this is the lattice. While basically an ultraviolet regulator, the lattice avoids the use of a perturbative expansion. I discuss the historical circumstances that drove us to this approach, which has had immense success, convincingly demonstrating quark confinement and obtaining crucial properties of the strong interactions from first principles.

description: Let M be a surface, perhaps with boundary, and either compact, or with a finite number of points removed from the interior of the surface. We consider the inclusion i: F\_n(M) --\textgreater{} M^n of the nth configuration space F\_n(M) of M into the n-fold Cartesian product of M, as well as the induced homomorphism i\_\#: P\_n(M) --\textgreater{} (π\_1(M))^n, where P\_n(M) is the n-string pure braid group of M. Both i and i\_\# were studied initially by J.Birman who conjectured that Ker(i\_\#) is equal to the normal closure of the Artin pure braid group P\_n in P\_n(M). The conjecture was later proved by C.Goldberg for compact surfaces without boundary different from the 2-sphere S^2 and the projective plane RP^2. In this paper, we prove the conjecture for S^2 and RP^2. In the case of RP^2, we prove that Ker(i\_\#) is equal to the commutator subgroup of P\_n(RP^2), we show that it may be decomposed in a manner similar to that of P\_n(S^2) as a direct sum of a torsion-free subgroup L\_n and the finite cyclic group generated by the full twist braid, and we prove that L\_n may be written as an iterated semi-direct product of free groups. Finally, we show that the groups B\_n(S^2) and P\_n(S^2) (resp. B\_n(RP^2) and P\_n(RP^2)) have finite virtual cohomological dimension equal to n-3 (resp. n-2), where B\_n(M) denotes the full n-string braid group of M. This allows us to determine the virtual cohomological dimension of the mapping class groups of the mapping class groups of S^2 and RP^2 with marked points, which in the case of S^2, reproves a result due to J.Harer.

description: Previously, [1207.0458] proposed an astrophysical explanation of narrow gamma-ray line-like feature(s) at ~100 GeV from Galactic Center region observed by Fermi/LAT [1205.4700]. The model of [1207.0458] is based on the inverse Compton scattering of external ultra-violet/X-ray radiation by a cold ultra-relativistic electron-positron pulsar wind. We show that the extra broad ~30 MeV component should arise from Comptonization of cosmic microwave background radiation. We estimate the main parameters of this component and show that it can be detectable with MeV telescopes such as CGRO/COMPTEL. The location of CGRO/COMPTEL unidentified source GRO J1823-12 close to excess of 105-120 GeV emission (Reg.1 of [1205.4700]) can be interpreted as an argument in favour of astrophysical model of the narrow feature(s) at ~100 GeV.

description: Localized prostate cancer, where an optimum treatment choice is characterized by uncertainty and ambiguity, often creates a situation in which patients need more information to make treatment decisions (Snow et al., 2007; Wilt et al., 2008). The purposes of this study were: (1) to describe physicians' communication with African American and Caucasian men during treatment decision making consultations for localized prostate cancer, and (2) to examine whether there was a variation in physician communication patterns, specifically information-giving and partnership-building behaviors, by the race, education level, and age of the patient. This study was a secondary analysis of data from a larger completed study, Decision Making under Uncertainty in Men with Prostate Cancer Patients (R01 NR008144-01, Merle H. Mishel, PI and Barbara B. Germino, Co-PI). Eight physicians were subjects in this study. Forty-five men comprised the patient sample. Thirteen of the men were African American and 32 were Caucasian. Physicians in this sample used information-giving behaviors more often with patients who were less than or equal to 65 years old, who had 13 or more years of education, and with Caucasians (as compared to African Americans). Differences between the mean numbers of information-giving utterances by age, education and race using independent t-tests were significant by patient age, but not by patient education or race. Similar to information-giving, physicians were more apt to use partnership-building with Caucasian men (as compared to African American men), those younger than 65, and those who had more than a high school education. Using independent t-tests, the differences between mean numbers of partnership-building utterances by age, education and race were not significant. Physicians used both facilitative and accommodative partnership-building with patients who were younger, more educated, and Caucasian. Physicians in this sample used both facilitative and accommodative partnership-building more often with men younger than 65, having 13 or more years of education, and with Caucasians (as compared to African Americans). Examination of differences between mean facilitative and accommodative partnership-building utterances by age, education and race of the patient using independent t-tests indicated that they were not significant. Overall, physicians were less engaged in partnership-building than information-giving in these consultations.

Vortex with four-fold defect lines in a simple model of self-propelled particles

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We studied formation of vortex with four-fold symmetry in a minimal model of self-propelled particles, confined inside a squared box, using computer simulations and also theoretical analysis. In addition to the vortex pattern, we observed five other phases in the system: homogeneous gaseous phase, band structures, moving clumps, moving clusters and vibrating rings. All six phases emerge from controlling strength of noise and contribution of repulsion and alignment interactions. We studied shape of the vortex and its symmetry in detail. The pattern shows exponential defect lines where incoming and outgoing flows of particles collide. We show that alignment and repulsion interactions between particles are necessary to form such patterns. Finally, we derived hydro-dynamical equations for our model and compared them with the results of both computer simulations and Quincke rotors. A good agreement between the three is observed.

Identity in its making: playing the difference in the music of Baay Fall
Creators: name: Bocci, Paolo

description: What is the role of musical expressions in the life of the Baay Fall sect? Which tensions is this music able to bring to light? Which contradictions are held together in their practices? What do those chants say that cannot be expressed in other forms, namely in the theological discourse? Baay Fall is a fundamentalist sect within the Muslim brotherhood of Mourid in Senegal. Drawing on an ethnographic field work during the last summer, I trace in my paper some of the threads that intertwine music and the social in the Baay Fall identity. Baay Fall rarely acknowledge, and with unease, their music. During my three-month field work I was often advised to change my study interest into the serious matter, their religious doctrine. Yet music thrives as a religious expression, political strategy, and sometime profane leisure. This contradiction is not an isolated case in describing the BF world. Music of Baay Fall does not just reflects, rather it engages in the exchanges with internal tensions and external pressures; it creates, appropriates, and reuses fragments of identity in the dialogic and contested everyday making of their social and religious belonging. Customs, doctrine, and rituals define genealogies of belonging that overlay and intersect among them. Some of these contradictions, at the core and the periphery of their being, find their eminent emergence in BF music.
