Determinants of sexual arousal and accuracy of its self-estimation in sexually functional males

Men with and without sexual dysfunction present with varying patterns of agreement between subjective estimates of sexual arousal and more objective psychophysiological measures of the same construct. This relative accuracy seems to be associated with sexual function, with men who have sexual dysfunction presenting less accurate estimations (mostly reporting below measured arousal levels). The purpose of this study is to clarify the processes underlying sexual arousal and the accuracy of its self-estimation. We looked at potential predictors of sexual arousal (subjective and physiological) and accuracy in estimating objective sexual arousal in a sample of 60 sexually functional males. Predictors included pre-existing sexual attitudes (erotophobia), both trait and state positive and negative affect, self-focused attention, and interoceptive awareness. Results indicate that this sexually functional sample generally reported below their own erection level. Interestingly, trait negative affect was associated with somewhat lower levels of subjective arousal and higher levels of physiological arousal. On the other hand, state positive affect facilitated both subjective and objective arousal and increased somewhat the accuracy of estimates of erectile responding. Pre-existing sexual attitudes as well as variations in self-focused attention and interoceptive awareness evidenced little effect on sexual arousal or the accuracy of its estimation.     

Artificial neural networks and center-of-pressure modeling: a practical method for sensorimotor-degradation assessment

Numerous methods for studying the prevention of falls and age-related sensorimotor degradation have been proposed and tested. Some approaches are too impractical to use with seniors or too expensive for practitioners. Practitioners desire a simple, reliable technique. The goals of this research were to develop such an approach and to apply it in exploring the effect of Tai Chi on age-related sensorimotor degradation. The method employed artificial-neural-network (ANN) models trained by using individuals' center-of-pressure (COP) measurements and age. Ninety-six White and Chinese adults without Tai Chi training were tested. In contrast, a third group, Chinese seniors with Tai Chi training, was tested to ascertain any influence from Tai Chi on sensorimotor aging. This study supported ANN technology with COP data as a feasible tool in the exploration of sensorimotor degradation and demonstrated that Tai Chi slowed down the effects of sensorimotor aging.     

Contextual assessment of couples therapy: the Clinical Discourse Q-Sets

This article describes a method for creating highly contextual assessments of couples therapy interaction using concepts from Systemic Functional Linguistics (SFL). According to SFL, talk in interaction serves three primary functions: to mediate social relations, to negotiate representations of reality, and to organize and structure the event as coherent. These concepts are operationalized using observational q-methodology. The Clinical Discourse Q-Sets (CDQS) include three separate q-sets for use by trained observers in rating 12-min segments of couples therapy conversation. Each q-set captures one aspect of the communication process as defined by Systemic Functional theory. Good-to-high reliabilities for the q-set profiles over various (n = 16) couples therapy episodes were found. Preliminary evidence for the conceptual structure and clinical validity of the system was found.     

A Taxometric Analysis of Problem Gambling Data from a South African National Urban Sample

We investigate the question whether problem gambling (PG) in a recent South African sample, as measured by the Problem Gambling Severity Index (PGSI), is dimensional or categorical. We use two taxometric procedures, Mean Above Minus Below A Cut (MAMBAC) and Maxim Covariance (MAXCOV), to investigate the taxonic structure of PG as constructed by the PGSI. Data are from the 2010 South African National Urban Prevalence Study of Gambling Behavior. A representative sample of the urban adult population in South Africa (N = 3,000). Responses are to the 9 item PGSI. MAMBAC provided positive but modest evidence that PG as measured by the PGSI was taxonic. MAXCOV pointed more strongly to the same conclusion. These analyses also provide evidence that a PGSI cutoff score of 10 rather than the standard 8 may be called for. PG as constructed by the PGSI may best be thought of as categorical, but further studies with more theory based measurements are needed to determine whether this holds in a wider range of samples and for other screens. A higher cutoff score may be called for on the PGSI when it is used for research purposes to avoid false positives.     

Pseudolikelihood estimation in a class of problems with response-related missing covariates

Many practical situations involve a response variable Y and covariates X , where data on (Y, X ) are incomplete for some portion of a sample of individuals. We consider two general types of pseudolikelihood estimation for problems in which missingness may be response-related. These are typically simpler to implement than ordinary maximum likelihood, which in this context is semiparametric. Asymptotics for the pseudolikelihood methods are presented, and simulations conducted to investigate the methods for an important class of problems involving lifetime data. Our results indicate that for these problems the two methods are effective and comparable with respect to efficiency.     

The Impact of Educational Homogamy on Isolated Illiteracy Levels

In this article, we explore the impacts that education expansion and increased levels in educational homogamy have had on couples’ isolated illiteracy rates, defined as the proportion of illiterates in union that are married to an illiterate partner. First, we develop the methodology to decompose isolated illiteracy rates into two main components: one related to level of homogamy among illiterates, and the other related to the educational distribution of the spouses. Second, we use harmonized international census microdata from IPUMS and DHS data for 73 countries and 217 samples to investigate which of the two components is more important in shaping the level of isolated illiteracy. Our results indicate that the expansion of literacy has been more powerful than the increases in the tendency toward homogamy in its impact on isolated illiteracy rates. As the percentage of illiterates decreases over time, an increasingly large proportion of them marry literate individuals, showing that opportunities for intermarriage among illiterates expand despite the strengthening of homogamy.     

Validation of a Multi‐Dimensional Measure of Strategy Development Processes

In this paper, we present evidence on the measurement properties of an instrument that assesses six dimensions of organizational strategy development. These dimensions are labelled planning, incrementalism, cultural, political, command and enforced choice. Using data from 5332 managers, results indicate the instrument has acceptable reliability and validity. Exploratory factor analysis confirms its underlying structure. Generally, the sub‐scales have acceptable internal reliability and inter‐rater reliability at the organizational level (n = 770 organizations). Further, using data aggregated at the organizational level, the sub‐scales are judged to have acceptable validity from the pattern of correlations amongst the six dimensions and with other variables.     

The incorporation of gender scholarship into sociology

The prospects of an intellectual revolution in sociology informed in part by a feminist perspective loomed large in the early 1970s. Following Ward and Grant's (1985) empirical examination of gender and feminist scholarship in sociology journals between 1974 and 1983, our research provides an empirical assessment of the “second ten years” after the feminist critique of the discipline, 1984–1993. Specifically, we examine the incorporation of gender-content scholarship into mainstream sociology journals. Our research also assesses the extent to which gender-content scholarship published in these journals is feminist-oriented or not and the extent to which this is influenced by the sex of authors, the type of journal, and the sex composition of editorships and editorial boards. Our findings indicate that although there were more gender- and feminist-oriented articles published in the recent ten-year period, proportionally there were fewer feminist-oriented articles than in the previous ten-year period. Our findings suggest that a feminist revolution in sociology is not likely to occur anytime soon, although the assimilation of feminist scholarship into sociology is occurring along the lines of other critical intellectual movements in recent decades.

Development of intercultural competence among US American teachers: professional development factors that enhance competence

The increasing diversity of the student age population in the USA calls for increased cultural competence on behalf of educators to effectively teach students. This article reports on a study of a suburban school district’s initiatives that utilized the Development Model of Intercultural Sensitivity, the Intercultural Development Inventory (IDI) as a baseline measurement tool, and subsequent professional development for teachers, to promote the development of intercultural competence. ANOVA and regression analysis models were used to determine the variables that affect teachers’ perceived intercultural competence after their participation in professional development.
