Nonverbal decoding skill and attention to nonverbal cues: A research note

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.

A Review of the High-Level Nuclear Waste Repository Siting Analysis

We critique two 1986 Department of Energy reports concerning the selection of sites for characterization as the nation's first high-level nuclear waste repository. We find that the multiattribute utility analysis of the five nominated sites was well done, although we express concern about the assessed probabilities, question the construction of two important attribute scales, and disagree with some of the value tradeoffs that were used. In contrast, we find the logic of the recommendations report to be weak and unconvincing.     

A mixture model for random graphs

The Erdös–Rényi model of a network is simple and possesses many explicit expressions for average and asymptotic properties, but it does not fit well to real-world networks. The vertices of those networks are often structured in unknown classes (functionally related proteins or social communities) with different connectivity properties. The stochastic block structures model was proposed for this purpose in the context of social sciences, using a Bayesian approach. We consider the same model in a frequentest statistical framework. We give the degree distribution and the clustering coefficient associated with this model, a variational method to estimate its parameters and a model selection criterion to select the number of classes. This estimation procedure allows us to deal with large networks containing thousands of vertices. The method is used to uncover the modular structure of a network of enzymatic reactions.     

城市化、分权与农村生活的重组

文章关注于发展中国家城市化的当代模式，并探讨这些模式对农村发展的涵义。发展中国家的不同国家和地区之间的城市化并不是统一的模式，且当代城市化模式所导致的在农村-城市联系中经济和社会多样性的程度是前所未有的。移民和分权是城市化在微观层次的两方面。城市化必然意味着或是永久的或是暂时的从农村流向城市的人口的净转移，而这些移民也对农村地区不平等产生了影响。而发展中国家城市化的一个新特征表现在它是伴随着行政的分权而发生的。分权的一个结果是使影响地方发展的行动者增加，另一个结果是没有任何一个人可以垄断资源或外部联系和信息。     

Towards Balancing Power in Domestic Violence Relationships Response to Shaw & Pye

In contrast to Shaw and Pye, Wileman and Wileman argue that women are not powerless to influence positive change in relationships involving domestic violence. A balance of power can be attained by many women, without increasing the risk of retaliatory abuse, providing the authors' guidelines are observed. It is time to acknowledge and validate the rights and wishes of the many women victims who want their relationships to survive and the violence to stop.     

HISTORICAL AND CURRENT FACTORS DISCRIMINATING SEXUALLY FUNCTIONAL FROM SEXUALLY DYSFUNCTIONAL MARRIED COUPLES*

Clinical literature has noted numerous past and current psychosocial factors characteristicof sexually dysfunctional individuals. However, there is almost no empirical documentation of factorsdiscriminating sexually functional from dysfunctional couples. The present study compared the responses of 94 clinical couples accepted for sex therapy with 110 nonclinical couples, selected from the same community. The couples were in their mid-30s, married an average of 12 years, middle income, rather well educated, and over 75% had at least one child. Individuals completed a 517-question Personal History Questionnaire (PHQ), and sex and marital defensiveness scales. The PHQ wasclinically and empirically developed, resulting in 54 internally consistent scales. Major analyses tested the discriminating power of past and current PHQ scales. The best discriminators were sexual functioning scales, historical and affective scales for women, and current and fantasy scales for men. Several surprising results appeared, including the importance of first coitus and the lack of importance of marital satisfaction, communication and sexual history scales. Four conclusionswere discussed relevant to the separation of sex and relationship satisfaction, the separation of sexualfunctioning and sexual satisfaction, and the differential impact of sexual problems on men and women.     

The effects of alternating mand and tact training on the acquisition of tacts

Two training procedures were compared with respect to the average number of training trials it took to teach new verbal responses to normal children. Mand contingencies were alternated with tact contingencies in one condition while only tact contingencies were in effect in the other condition. Normal, preschool children served as subjects and toy parts were the objects that were to be named. The results indicated that it took, on the average, fewer trials to teach part names (tacts) in the mand-tact condition than in the tact only condition. Although more research is needed to confirm this, it appears that mand contingencies involve stronger controlling variables and can facilitate the acquisition of a tact repertoire.
