Correlation and covariance matrices provide the basis for all classical multivariate techniques. Many statistical tools exist for analyzing their structure, but, surprisingly, there are few techniques for exploratory visual display, and for depicting the patterns of relations among variables in such matrices directly, particularly when the number of variables is moderately large. This paper des...

This paper studies how national sentiment in the form of either a perception or a loyalty bias of bettors may affect pricing patterns on national wagering markets for international sport events. We show theoretically that both biases can be profitably exploited by bookmakers by way of price adjustment (odds shading). The former bias induces bookmakers to shade odds against the domestic team, th...

This paper presents a synthesisable VHDL model for a generalised multiplier capable of performing multiplication of both sign-magnitude and two’s complement operands. The multiplier is testable with a constant number of test vectors irrespective of operand word-lengths thereby reducing automatic test generation, simulation and testing times. The model has been used successfully for generating m...

Abstract Through the interpretation of texts, and subsequent creation of social reality, mediated representations are often seen to be presented within the certain of ideological discourses that reflect the existing power structures. The main objective of this paper is to analyze television commercials with an emphasis on gender roles to decode the main elements of a dominant discourse (prefer...

The experiment was carried out to examine the organic acids production of rice straw fermented with some types of microorganisms at different temperatures. The experiment was designed as Split Plot-Completely Randomized Design. The main plot was temperatures treatments (25, 35, 45°C) and the sub plot were microorganisms (Control, Control+Mollases, Lactobacillus fermentum, Bacillus subtilis, Bac...

Productions of σ meson in J/ψ and ψ(2s) decays Abstract Productions of scalar meson(σ) in the decays of J/ψ → ω + σ,J/ψ → γ + σ and ψ(2s) → ω + σ, J/ψ + σ, γ + σ and ee + annihilations in the regions of J/ψ and ψ are studied 1

PURPOSE To investigate if the performance on linguistic tasks would be predictive of orthographic domain and quality of written productions. METHODS Participants were 82 fourth graders of Elementary Education, from public and private schools of São Paulo, with ages ranging from 9 years to 10 years and 2 months. The test battery was composed of an expressive vocabulary test, phonological aware...
