The present study examined differences in pelvic vasocongestion as a function of negative attitudes toward masturbation. Pelvic vasocongestion was measured thermographically, which is a noninvasive means of detecting and photographing individual heat patterns to indicate physiological condition and functional changes within. The results indicated that women, with positive attitudes toward masturbation, who read an erotic story, experienced the greatest increase in pelvic vasocongestion. This and other findings were discussed in terms of masturbation acting to facilitate the patterning of sexual arousal and orgasmic functioning, especially in regard to creating the capacity for pelvic engorgement.  相似文献

Attributions made by children and their parents for the cause of the child's clinical problem were monitored during assessment interviews. Results support previously observed differences obtained through questionnaires, with parents making more attributions than their children to characteristics of the child. This pattern was affected by variations in interview format. Parents and children differed in the locus of their attributions when interviewed individually, but these differences were not present when families were interviewed with both parents and children present. Implications for the methodology of attribution research with child-clinical populations are highlighted.  相似文献

This paper proposes an approach for strategic revenue management under uncertainty for real estate projects. It integrates three modelling techniques: first, artificial neural network integrated support vector machines for forecasting the profit and loss‐making real estate residential projects; second, analytical network process approach using decision making trials and evaluation laboratory methodology for establishing interrelationships among factors; and third, multiobjective genetic algorithm approach for obtaining optimal numbers and types of apartments in a real estate project. We compare the respective revenues generated with the new number of apartments and price from the suggested revenue maximization model and that of the old practiced one through a case study of India.

The sociological literature has produced a remarkably consistent picture of the quantitative patterns of religious disaffiliations in Western countries. This article argues, and demonstrates, that strong changes in a social context may lead individuals to disaffiliate rapidly, leading to very different aggregate effects from those in the “western model.” We use the unique situation of the separation of Germany from 1949 to 1989 and its subsequent reunification as a “natural experiment” to show just how much the relationships routinely found can be disrupted under changed conditions. The state socialist “treatment” affected religious disaffiliations in East Germany profoundly as it (a) made disaffiliations 10 times more probable in the East than in the West in the 1950s and 1960s, (b) shielded East German church members from factors that led to mass disaffiliations in the West in the late 1960s and early 1970s, (c) reversed the education‐disaffiliation link in the East, thus making disaffiliation more likely among the less educated, and (d) led to an especially strong increase in disaffiliations in the East right after the reunification  相似文献

America's judicial system is both exceptionally punitive and demonstrably unjust toward racial minorities. While these dual realities are structured into America's institutions, we propose they are also partially sustained by the intersection of ideologies that are both racialized and sacralized. Using multiple waves of the General Social Surveys and a unique measure that asks Americans to choose between two forms of judicial injustice (wrongful conviction or erroneous acquittal), we examine how white racial identity intersects with biblical literalism to bolster America's bent toward unjust punitiveness. In the main effects, Americans who affirm biblical literalism are more likely to show a preference for convicting the innocent, as are whites compared to Black Americans. Examining interaction effects, however, we find whiteness moderates the influence of biblical literalism such that only white biblical literalists (as opposed to non‐white biblical literalists or white non‐biblical literalists) are more likely to prefer wrongful conviction. Indeed, in our full model, being a white biblical literalist is the strongest predictor of preferring wrongful conviction. We theorize that preference for wrongful conviction over erroneous acquittal stems, at least in part, from the combination of sacralized authoritarianism and perceived racial threat.  相似文献
