M Hall 《Journal of homosexuality》1987,14(1-2):137-156
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

On the momentum of population growth 总被引:4,自引:0,他引:4
Nathan Keyfitz 《Demography》1971,8(1):71-80
If age-specific birth rates drop immediately to the level of bare replacement the ultimate stationary number of a population will be given by (9): $$\left( {{\textstyle{{b\mathop e\limits^ \bullet {}_0} \over {r\mu }}}} \right)\left( {\frac{{R_0 - 1}}{{R_0 }}} \right)$$ multiplied by the present number, where b is the birth rate, r the rate of increase, \(\mathop e\limits^ \bullet _0 \) the expectation of life, and R 0 the Net Reproduction Rate, all before the drop in fertility, and μ the mean age of childbearing afterwards. This expression is derived in the first place for females on the stable assumption; extension to both sexes is provided, and comparison with real populations shows the numerical error to be small where fertility has not yet started to drop. The result (9) tells how the lower limit of the ultimate population depends on parameters of the existing population, and for values typical of underdeveloped countries works out to about 1. 6. If a delay of 15 years occurs before the drop of the birth rate to replacement the population will multiply by over 2. 5 before attaining stationarity. The ultimate population actually reached will be higher insofar as death rates continue to improve. If stability cannot be assumed the ultimate stationary population is provided by the more general expression (7), which is still easier to calculate than a detailed projection. 相似文献

The Analysis of Verbal Behavior - In a recent paper, Mabry (1993) examines various aspects of Skinner’s (1957) treatment of grammar, and he compares it with cognitivist approaches. Mabry... 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

Winifred A. Nathan 《Children and youth services review》1984,6(4):329-344
This article examines selected United States Supreme Court decisions from 1923 through the 1984 term of the Court. The selection, which includes Wisconsin v. Yoder, In re Gault, In re Winship, and Schall v. Martin, traces and illustrates the triangle of interest among parent, child, and state as parens patriae, when the issue raised is the interest of children. The focal question is: Have children been recognized as having their own individual Constitutional rights, or have their rights been merged with those of their parents and/or the state standing in the place of the parents? 相似文献
