Estimation of the prior distribution of the binomial parameter nbased on a system of orthogonal polynomials, the Poisson-Charlier polynomials, is studied. It is shown that the resulting estimator is mean squared consistent with rate O(N ε-1), where Nis the sample size and ε> 0 is arbitrarily small. 相似文献

We investigated implicit versus explicit activation of the sexual system using a priming paradigm in which sexual slides were preceded by either sexual or neutral primes. In the first experiment, primes were made inaccessible to conscious cognitive elaboration. Identification of sexual targets was facilitated by sexual primes, indicating that sexual representations in memory can be activated automatically. In the second experiment, in which primes were presented at a conscious level, identification of sexual targets was decelerated by sexual primes. Primes elicited subjective sexual arousal in Experiment 2 only, demonstrating that the activation of subjective experience requires conscious cognitive elaboration. With the addition of a sexually specific physiological measure, to be constructed to measure initial genital responses, this paradigm may help elucidate activational mechanisms of sexual response. 相似文献

The Youth Program Quality survey, a 24-item survey of youth participant perceptions of program quality, based on program elements identified by the National Research Council (NRC) and Institute of Medicine, was developed and piloted with 614 younger teens (ages 10–13 years) and 486 older teens (ages 14–17 years) who attended 4-H camps and conferences. Evidence is presented for content and construct validity. In addition, the overall instrument demonstrated high reliability, as measured by Cronbach's alpha, generally ranging from .70 to .96, and moderate subscale reliability of .60 or higher on four factors in the younger sample (α=.60 or higher on four factors in the older sample). Results are discussed in terms of goodness of fit to the National Research Council model, the significance of youth voice in assessment of program quality, developmental differences in perceptions of quality, and programming design. Recommendations are offered for practice, research, and policy. 相似文献
