Sexual practices at last heterosexual encounter and occurrence of orgasm in a national survey

In order to examine factors associated with orgasm in heterosexual encounters, we analyzed data from the Australian Study of Health and Relationships, a national telephone survey of sexual behavior and attitudes and sexual health knowledge carried out in 2001-2002 with a representative sample of 19,307 Australians aged 16 to 59. Respondents were asked whether at their last sexual encounter they gave or received manual stimulation and oral sex, had vaginal intercourse or anal intercourse, and whether they had an orgasm. Vaginal intercourse was the dominant practice: 95% of encounters included it. Of the 64 possible combinations of these practices, 13 account for 93% of encounters: vaginal intercourse alone (12%), vaginal + manual stimulation of the man's and/or woman's genitals (49%), and vaginal intercourse + manual + oral (32%). Encounters may also have included other practices. Men had an orgasm in 95% of encounters and women in 69%. Generally, the more practices engaged in, the higher a woman's chance of having an orgasm. Women were more likely to reach orgasm in encounters including cunnilingus. This is the first large-scale empirical study worldwide to link specific practices with orgasm. Demographic and sexual history variables were comparatively weakly associated with orgasm.     

Interpersonal Reasons for Interpersonal Perceptions: Gender-incongruent Purpose Goals and Nonverbal Judgment Accuracy

Women’s tendency to outperform men on measures of accuracy in interpreting the meaning of nonverbal behavior might be due to such measures being more congruent with women’s interpersonal goals than men’s. The present study examined undergraduate men’s and women’s (N = 41) nonverbal judgment accuracy on the Interpersonal Perception Task-15 (IPT-15; Costanzo & Archer, 1993 [.The interpersonal perception task-15 (IPT-15). Berkeley: University of California Center for Media and Independent Learning) when the purpose for using their judgment skills was manipulated to be either congruent or incongruent with stereotypic “masculine” and “feminine” interpersonal goals. Results showed that each gender was at a relative disadvantage in judgment accuracy in the gender-incongruent goal conditions: women were relatively less accurate when they thought the IPT-15 measured judgment skills of use to interrogators in the military, whereas men were relatively less accurate when they thought the IPT-15 measured judgment skills of use to social workers in the social services. Discussion centers on the importance of matching individuals’ interpersonal goals to the purpose goals of the measure when using measures of interpersonal sensitivity.

A hierarchical Bayesian model for predicting the functional consequences of amino-acid polymorphisms

Summary.  Genetic polymorphisms in deoxyribonucleic acid coding regions may have a phenotypic effect on the carrier, e.g. by influencing susceptibility to disease. Detection of deleterious mutations via association studies is hampered by the large number of candidate sites; therefore methods are needed to narrow down the search to the most promising sites. For this, a possible approach is to use structural and sequence-based information of the encoded protein to predict whether a mutation at a particular site is likely to disrupt the functionality of the protein itself. We propose a hierarchical Bayesian multivariate adaptive regression spline (BMARS) model for supervised learning in this context and assess its predictive performance by using data from mutagenesis experiments on lac repressor and lysozyme proteins. In these experiments, about 12 amino-acid substitutions were performed at each native amino-acid position and the effect on protein functionality was assessed. The training data thus consist of repeated observations at each position, which the hierarchical framework is needed to account for. The model is trained on the lac repressor data and tested on the lysozyme mutations and vice versa. In particular, we show that the hierarchical BMARS model, by allowing for the clustered nature of the data, yields lower out-of-sample misclassification rates compared with both a BMARS and a frequen-tist MARS model, a support vector machine classifier and an optimally pruned classification tree.

Cultural Sociology, Modes of Inquiry, and Political Analysis: A Rejoinder to Steensland

Closely bounded research programs are both common and effective in sociology. Describing such programs as operating with a "restricted code" is deeply problematic. These matters aside, the remarkable rise of cultural sociology in fact reflects adaptation to sociology's disciplinary norms and core thematic concerns. Steensland (2009) might better have reversed his argument: faced with the achievements of cultural analysis, the slumbering giant called "mainstream sociology" should wake up.     

The Society of Society: The Grand Finale of Niklas Luhmann

This paper introduces Niklas Luhmann's final work, Die Gesellschaft der Gesellschaft (The Society of Society). According to Luhmann, sociologists have failed to produce even a partially adequate theory of society. Epistemological obstacles and humanist concerns for rationality and justice have prevented true progress in the discipline. With his "radically antihumanist, radically antiregional, and radically constructivistic" social system theory, Luhmann intends to bring about a sociological enlightenment. Die Gesellschaft der Gesellschaft focuses on communication as the only genuinely social phenomenon. Social systems differentiate and evolve as they communicate in three separate dimensions: the social, temporal, and functional. The path of evolution results from a history of variation, selection, and restabilization within these dimensions. Communication, bit by bit, produces social structures that, recursively, produce future structures. Society is communication. Sociology, as the science of society, is communication about how different societal systems operate, communicate, evolve, and maintain their boundaries.     

Concept maps as network data: Analysis of a concept map using the methods of social network analysis

Concept mapping is a method that creates a visual representation that illustrates the thoughts, ideas, or planned actions that arise from a group of stakeholders on a particular issue. Social network analysis is a method that likewise creates a visual representation of data; a network map typically represents people and the connections, or lack thereof, between these people regarding a particular issue. While the goals of these two methods differ, the underlying data structures are similar; a network of relationships between data elements. Social network analysis is explored here as a supplement to concept mapping. A secondary analysis of a concept map to define to leadership needs was conducted using social network analysis. The methods and the implications for supplementing the analysis of concept maps and debriefing results with stakeholders are discussed.
