The Construction of Black Masculinity: White Supremacy Now and Then

Abstract: How can a White supremacist nation, which subjects Black men to ongoing racism and demonization, at the same time admire and worship Black men as athletes? The author argues that key elements of White supremacy and the new racism are reinforced by popular representations of Black male athletes. In viewing far-Right White supremacist and sports cultures, two sites representing seemingly opposite ends of the spectrum of contemporary racism, the author examines the continuing significance of the historical image of the buck and the obsession with controlling and “taming” Black male bodies. The author examines four common themes that permeate the contemporary construction of Black masculinity and work to justify color-blind racism and inequality: a continued emphasis on Black bodies as inherently aggressive, hypersexual, and violent; concern with taming and controlling Black males; inequality depicted as a product of a deficient Black culture; and the naturalization of White supremacy and White male superiority.

Process for converting programs in high-level programming languages to a unified executable for hybrid computing platforms

Abstract: A system and method for compiling computer code written to conform to a high-level language standard to generate a unified executable containing the hardware logic for a reconfigurable processor, the instructions for a traditional processor (instruction processor), and the associated support code for managing execution on a hybrid hardware platform. Explicit knowledge of writing hardware-level design code is not required since the problem can be represented in a high-level language syntax. A top-level driver invokes a standard-conforming compiler that provides syntactic and a semantic analysis. The driver invokes a compilation phase that translates the CFG representation being generated into a hybrid controlflow-dataflow graph representation representing optimized pipelines logic which may be processed into a hardware description representation. The driver invokes a hardware description language (HDL) compiler to produce a netlist file that can be used to start the place-and-route compilation needed to produce a bitstream for the reconfigurable computer. The programming environment then provides support for taking the output from the compilation driver and combining all the necessary components together to produce a unified executable capable of running on both the instruction processor and reconfigurable processor.

Magnetic excitations in layered media: Spin waves and the light-scattering spectrum

Abstract: We present an analysis of the spin-wave spectrum of a semi-infinite stack of ferromagnetic films, each of which is separated by a gap filled by a nonmagnetic medium. This is done within a formalism which includes the Zeeman and dipolar contributions to the spin-wave energy, with exchange omitted. We then calculate the spin-wave contribution to the Brillouin spectrum of such a system, in the backscattering geometry. The aim is to compare the spectrum for scattering from a sample with this geometry, with that from an isolated film. Two features unique to the stack appear in the spectrum. Each film, in isolation, possesses surface spin waves on its boundaries (Damon-Eshbach waves). In the layered geometry these interact to form a band of excitations of the array, which has nonvanishing component of wave vector normal to the stack. We find a feature in the spectrum associated with scattering from this band of modes; the position of the peak is controlled by dispersion introduced by interfilm interactions. Under certain conditions, the semi-infinite stack possesses a surface spin wave, whose eigenfunction is a linear superposition of individual film states, with amplitude that decays to zero as one moves down into the stack interior. This mode also produces a distinct feature in the light-scattering spectrum. These points are illustrated with a series of calculations of the spectrum, for parameters characteristic of layered ultrathin coherent structures.

Customer-to-customer exchange: Its MOA antecedents and its impact on value creation and loyalty

Abstract: Value creation through customer-to-customer exchange occurs when the perceived benefits of a company’s offering are increased as a result of customers’ interaction with one another. C2C exchange exists in a wide variety of service environments, both online and face-to-face. Drawing on the motivation, opportunity, and ability (MOA) framework, this research presents and tests a theoretical model that examines antecedents and outcomes of C2C exchange in the context of face-to-face networking behaviors at professional association meetings. Data were obtained from a survey of conference attendees, and the hypotheses were tested using moderated regression and path analysis. The results show a three-way interaction effect among the MOA factors, that the MOA model does predict the level of C2C exchange, and that C2C exchange does enhance service value perceptions and customer loyalty intentions.

Characteristics of Bismuth Layered SrBi2Ta2O9 Thin-Film Capacitors and Comparison with Pb(Zr, Ti)O3

Abstract: We have developed the series of thin-film bismuth layer structured ferroelectric (BLSF) materials such as SrBi2Ta2O9, SrBi2Nb2O9, SrBi4Ti4O15 and their solid solutions using metallo-organic-decomposition (MOD) spin-on coating techniques. We found that SrBi2Ta2O9 is one of the best potential candidate materials for ferroelectric nonvolatile memories. The SrBi2Ta2O9 thin-film capacitor had the remanent polarization (P r+-P r-) of 20 µ C/cm2, coercive field of 35 kV/cm and dielectric constant of 250. SrBi2Ta2O9 thin film on platinum electrode has fatigue-free characteristics for up to 2×1011 cycles without requiring any complicated electrode system such as conductive oxide. Moreover, SrBi2Ta2O9 thin film has many advantages, e.g., high signal/noise ratio of 8 at 1.2 V, low-voltage operation at as low as 1 V, long data-retention, little surface effect, superior imprint properties and low leakage current. We considered that these advantages are due to (1) less space charge and (2) the inherent domain motion.
