Stein's method is used to prove the Lindeberg-Feller theorem and a generalization of the Berry-Esséen theorem. The arguments involve only manipulation of probability inequalities, and form an attractive alternative to the less direct Fourier-analytic methods which are traditionally employed. 相似文献

The many factors--social, cultural, psychological--that shape homosexual sexual expression render purely behavioral sex therapy models one-dimensional and ineffective for lesbian clients with sexual presenting problems. Though a behavioral approach may be useful later in the treatment of such problems, the effective clinician must first address the inimical social and cultural contexts that frame lesbian sexual impasses. This paper offers specific techniques, both direct and indirect, designed to illuminate and neutralize these contexts. Additionally, the author presents a sequence of sensate focus exercises tailored to the particular needs of lesbian couples. 相似文献

The technique of multi-sort analysis was used to compare the relative duration of use of oral and intrauterine contraception among low socio-economic groups in Baltimore City. The clinical records of over 12,000 women who had received contraception through the Baltimore public services were analyzed. The type of method a woman used was found to be the most important factor affecting her probability of continuing contraception. Her age, race, and how long she had been using the method also influenced this probability. The strictness of the criteria used for the definition of continuation rates and the fact that experience was incomplete for many intrauterine contraceptors probably in part explain the somewhat low continuation rates obtained for both methods. It is suggested that the intrinsic characteristics of each method may lead to a clinical impression favoring the oral even when statistical evidence, as presented here, favors the intrauterine method. 相似文献

A measure of differential preference for attending to three channels of nonverbal communication was developed, with which scores for differential attention to face, body, and voice tone were generated for 17 college subjects. These scores were correlated with subjects' nonverbal decoding accuracy in the same three channels as measured by a standard test of decoding nonverbal cues. Significant positive relationships between channel preference and accuracy were found for the two video channels; no relationship was found for the audio channel.This research was conducted while both authors held National Science Foundation Graduate Fellowships at Harvard University. They wish to thank Robert Rosenthal for advice, Peter L. Rogers for technical assistance and Myron Wish for valuable criticisms of an earlier draft. 相似文献

This note gives and discusses balanced row-and-column designs for experiments with two non-interacting sets of treatments, one set not being applied to all the rows. These designs are potentially useful for occasions when trees that have tested one set of experimental treatments are needed for testing a second set before the residual effects of the first have become negligible, but when the experimenter wishes to apply the second set to only some of the rows. The designs are appropriate if the residual and new effects do not interact. 相似文献
