Captain George Henry Lane‐Fox Pitt‐Rivers and the Prehistory of the IUSSP

Captain George Henry Lane‐Fox Pitt‐Rivers, Secretary General of the International Union for the Scientific Investigation of Population Problems (IUSIPP, 1928–ca. 1942), the precursor of today's International Union for the Scientific Study of Population (IUSSP, 1947–present), was a central figure in population science during the 1930s. With his pro‐Nazi activism, anti‐Semitism, Red‐baiting, and failure to leave any intellectual mark of consequence, he is an idiosyncratic and in some ways unattractive subject. However, an examination of Pitt‐Rivers's role as Secretary General reveals a wealth of information about the IUSIPP as it lurched toward collapse. It casts light, as well, on the struggle for scientific legitimacy between eugenic racialists and reformers in the 1930s, a struggle in which he played a controversial and divisive role. Using a combination of newly discovered and old archival material, this article traces Pitt‐Rivers's involvement with the Union, the British eugenics establishment, Nazi population science, and far‐right British politics during this turbulent decade when demography emerged as an international discipline.     

Sexual behavior among HIV-positive men who have sex with men: what's in a label?

Relatively little attention has been paid to the use and importance of labels used by men who have sex with men to describe insertive or receptive sexual behavior during intercourse. This study examines sexual self-labels, sexual behavior, HIV transmission risk, and psychological functioning among 205 HIV-seropositive men who have sex with men. The majority of participants (88%) identified as a top, a bottom, or versatile. Tops were more likely to engage in insertive anal intercourse than bottoms, and bottoms were more likely to engage in receptive anal intercourse than tops, with versatiles reporting intermediate rates of both behaviors. Although the results suggest preliminary evidence regarding the predictive utility of self-labels, sexual behaviors of self-label groups were greatly overlapping. Differences were found among self-label groups in gay self-identification, internalized homophobia, sexual sensation seeking, and anxiety. Results suggest an added value in assessing self-labels in addition to asking about sexual behavior.     

Therapeutic implications of viewing sexual identity in terms of essentialist and constructionist theories

One of the most challenging developments in recent historical studies and in empirical research in sociology has been constructionist theories relating to "sexual personalities." The "constructionist" view is that sexual identity is labile and can be therapeutically modified. In clinical work, this has presented an alternative view of the development of social sex-role and sexual orientation. Previously, views of sexual identity as a fixed personal characteristic (the "essentialist" view) provided clinicians with ways of treating psychologically distressed people either by transsexual conversion or aversion therapy. This article reviews some implications of "constructionist" and "essentialist" theory. It describes the author's clinical attempts to present constructionist views to clients who are in conflict about their sexual orientation and social sex-role. The article concludes that constructionist therapy has not taken into account clinical evidence that clients may adhere to "essentialist" beliefs.     

A Simple Adaptive Procedure Leading to Correlated Equilibrium

We propose a new and simple adaptive procedure for playing a game: ‘regret‐matching.’ In this procedure, players may depart from their current play with probabilities that are proportional to measures of regret for not having used other strategies in the past. It is shown that our adaptive procedure guarantees that, with probability one, the empirical distributions of play converge to the set of correlated equilibria of the game.     

The effect of the still‐face paradigm on infant behavior: A cross‐cultural comparison between mothers and fathers

Most still‐face paradigm (SFP) studies have been done in Western families with infant–mother dyads. The present study investigated the SFP pattern in 123 Dutch and 63 Chinese 4‐month‐old infants with mothers and fathers. The classic SFP effect was found for positive affect and gaze in both countries. For negative affect, Chinese infants showed a different SFP pattern than Dutch infants. With fathers, infants displayed a less pronounced SFP pattern for positive affect and an increase from the still face to the reunion for negative affect. Only a minority of infants showed the expected SFP pattern across episodes. Our findings support that infant emotion expression is influenced by parent gender and cultural context. An interesting avenue for further study is the exploration of the origins of within‐ and between‐gender and culture differences in affective communication between parents and infants.     

The Effects of Marital and Nonmarital Union Transition on Health

This study examines the effects of marital and nonmarital union transition on health. Utilizing Canadian longitudinal data, we find that exiting both marriage and cohabitation seems to have similar effects: Dissolving either union tends to be associated with a decrease in physical health, mental health, or both. With possible selection effects eliminated and protection effects held constant, we find that remaining in either type of union generally is associated with poorer health. We speculate that decreased union quality may account for this inverse relationship, and that protection effects may explain much of the reported health gains associated with union life.     

A Conditional Autoregressive Gaussian Process for Irregularly Spaced Multivariate Data with Application to Modelling Large Sets of Binary Data

A Gaussian conditional autoregressive (CAR) formulation is presented that permits the modelling of the spatial dependence and the dependence between multivariate random variables at irregularly spaced sites so capturing some of the modelling advantages of the geostatistical approach. The model benefits not only from the explicit availability of the full conditionals but also from the computational simplicity of the precision matrix determinant calculation using a closed form expression involving the eigenvalues of a precision matrix submatrix. The introduction of covariates into the model adds little computational complexity to the analysis and thus the method can be straightforwardly extended to regression models. The model, because of its computational simplicity, is well suited to application involving the fully Bayesian analysis of large data sets involving multivariate measurements with a spatial ordering. An extension to spatio-temporal data is also considered. Here, we demonstrate use of the model in the analysis of bivariate binary data where the observed data is modelled as the sign of the hidden CAR process. A case study involving over 450 irregularly spaced sites and the presence or absence of each of two species of rain forest trees at each site is presented; Markov chain Monte Carlo (MCMC) methods are implemented to obtain posterior distributions of all unknowns. The MCMC method works well with simulated data and the tree biodiversity data set.     

The Mental Health of the Childless Elderly

The substantial number of childless elderly in Canada and the United States raises important concerns about the nature of their family support, as well as their psychological well-being. Although the (mixed) effects of childlessness on the mental health of the elderly are well documented in the literature, little is known about the social distribution of psychological distress and depression within this population: how well the childless elderly live, the status of their mental health, and what factors affect their psychological well-being are all crucial questions that remain unanswered. This paper utilizes Pearlin et al.'s (1981) stress process model to examine psychological distress and depression among the childless elderly. Our empirical analysis uses a nationally representative sample of childless individuals aged 55 and over ( N = 2,311) from the 1996-1997 National Population Health Survey (NPHS), and generalized linear model (GLM) techniques. Generally, our results support the stress process model. We find that individual-level stressors exert a strong and consistently negative impact on psychological distress and depression. We also find significant buffering effects of (perceived) social support.     

Supervision in Family Therapy: A Developmental Perspective

A group model of supervision of family therapy was implemented by a team of three supervisors with doctoral students in counseling psychology. It was believed that such an approach would provide students with more opportunity to work as therapists with families and to observe a greater variety of families, therapists, and therapeutic styles than in other models. Interchange in supervisory sessions focused on co-therapy issues, observation skills, family dynamics, differing therapeutic techniques and approaches, and planning and goal setting in therapy. This experience contributed to the professional and personal growth and development of students.
