Recurrent pain in college students.

The authors investigated the prevalence of recurrent pain in a college student sample. Of the 1,564 students surveyed, 467 (29%) indicated that they had experienced recurrent pain at an intensity that was mostly in the mild-to-moderate range. Students who reported having recurrent pain were significantly older and more depressed than students who did not indicate they suffered from recurrent pain. Pain intensity was positively correlated (r = .14) with depression among the students who reported having recurrent pain. Implications of the findings for future research, treatment, and health promotion efforts are discussed.     

Is Gaydar Affected by Attitudes Toward Homosexuality? Confidence,Labeling Bias,and Accuracy

Previous research has largely ignored the relationship between sexual orientation judgement accuracy, confidence, and attitudes toward homosexuality. In an online study, participants (N = 269) judged the sexual orientation of homosexual and heterosexual targets presented via a series of facial photographs. Participants also indicated their confidence in each judgment and completed the Modern Homonegativity Scale (Morrison & Morrison, 2002). We found that (1) homosexual men and heterosexual women were more accurate when judging photographs of women as opposed to photographs of men, and (2) in heterosexual men, negative attitudes toward homosexual men predicted confidence and bias when rating men’s photographs. Findings indicate that homosexual men and heterosexual women are similar in terms of accuracy in judging women’s sexuality. Further, especially in men, homophobia is associated with cognitive biases in labeling other men but does not have a relationship with increased accuracy.     

Diffusive nested sampling

We introduce a general Monte Carlo method based on Nested Sampling (NS), for sampling complex probability distributions and estimating the normalising constant. The method uses one or more particles, which explore a mixture of nested probability distributions, each successive distribution occupying ∼e ⁻¹ times the enclosed prior mass of the previous distribution. While NS technically requires independent generation of particles, Markov Chain Monte Carlo (MCMC) exploration fits naturally into this technique. We illustrate the new method on a test problem and find that it can achieve four times the accuracy of classic MCMC-based Nested Sampling, for the same computational effort; equivalent to a factor of 16 speedup. An additional benefit is that more samples and a more accurate evidence value can be obtained simply by continuing the run for longer, as in standard MCMC.     

No associative biases in the first name cued recall procedure for eliciting personal networks

One thousand five hundred twenty-five respondents from a representative sample of adult residents of the state of Florida (USA) participated in a telephone survey on personal networks (McCarty et al., 1995). McCarty et al. (1995) elicited samples of alters from respondents' personal network with a first name cued recall interview procedure. This paper reports an assessment of associative biases involved with this technique in a further evaluation of the representativeness of the alter samples elicited with this method. Associative biases would be present if successively recalled alters are more likely to know each other or belong to the same social context (e.g., work, family, school) than alters not recalled successively. Such biases, if present, could influence the characteristics, and thus the representativeness, of the set of alters elicited, such as the density of ties. Analyses indicate that there are no associative biases in the first name cued recall procedure. Future research should investigate the possibility of associative biases in other methods for eliciting personal networks.     

The Continuing Dominance of Traditional Gender Roles in Southern Elections*

Objective. Studies of the election of women to public office have been increasingly encouraging about their prospects of female candidates. The purpose of this study is to examine the extent to which gender roles continue to influence the election of women to local office and the pool of candidates for higher office. Methods. Utilizing data on the gender of officials, the nature of the office, and constituency demographics from county elections in eight Southern states, we construct logit models of the election of women. Results. Women hold few local offices involved in fighting crime or of an executive nature. On the other hand, women routinely win election to process‐oriented offices with less discretion. Our analysis of constituency demographics reinforces our conclusions. Women win election in areas where the public office is relatively undesirable compared to other opportunities and the ratio of high‐quality male to high‐quality female candidates is relatively low. Conclusions. Although the frequent election of women to county office provides an expanded pool of female candidates for higher offices, it seems unlikely that women will find it as easy to move up the electoral ladder into the more competitive arena of high‐profile statewide and federal leadership offices.     

Continuity and change in contemporary Ulster Protestantism*

This paper explores current trends in religious practice, observance and belief in Ulster Protestantism for elements of continuity and change. Using historical and survey data it is clear that there are strong elements of both. However, Protestant religiosity is not changing to the point that it constitutes secularisation, as sociologists of religion understand it. Nor are new trends in religiosity weakening ethno‐national identities in Northern Ireland. This is because political identities are socially reproduced in ways that are independent of their religious roots and are thus unaffected by patterns of religiosity. Likely changes in Protestant religiosity in the future therefore offer no immediate panacea for altering the dynamics of Northern Irish politics.     

ANOMALIES, PROBINGS, INSIGHTS: KEN FOREMAN'S ROLE IN THE SAMPLING INFERENCE CONTROVERSY OF THE LATE 20TH CENTURY

This paper is based on the author's recollections of work done for and with E.K. Foreman, and later developments of that work. It describes most particularly the author's early intimations of the potential for using prediction models in survey sampling, the reasons why the use of such models, especially for inferential purposes, was so strongly resisted in the second half of the 20th century, the manner in which randomization and prediction inferences can be combined, and some advantages flowing from that combination.     

Optimal bid-ask price strategies

Economic analysis has begun to focus on the implications of transaction costs to trading in capital assets. Specifically, the economics of market making and the price of liquidity has received considerable attention. This paper formulates the market maker's bid-ask price decision as a semi-Markov decision process with the reward being a function of expected return and risk. Risk is intimately related to dealer inventory and hence the solution of the analysis specifies bid-ask price strategies which are inventory dependent. Numerical examples indicate the market maker's optimal bid-ask prices will tilt around the ‘assets’ equilibrium price to control inventory as well as influence expected profit.     

Exploitation in the new Marxism of collective action

The ‘new Marxism of collective action’is a term Lash and Urry have recently used to describe a new intellectual current in Marxism which seeks to apply rational choice theory, and particularly game theory, to key Marxian concepts like collective action, class, revolution and exploitation. This current is seen as part of a general shift within social science away from structure towards agency. This paper focuses on a concept which Lash and Urry's outline ignored: namely, exploitation. Granting the concept this attention is useful for a number of reasons. Firstly, by summarizing the general debate on the concept, both within the new Marxism of collective action and outside, the paper allows the discussion of exploitation to be placed in the context of the more general debate between structuralist and humanistic versions of Marxism; especially in the context of the debate about whether there can be a Marxist theory of ethics and injustice. Secondly, by outlining how the concept is understood by advocates of the new Marxism of collective action, the paper accords the concept the central status which advocates reserve for it. In consequence, the paper identifies differences between advocates of the new Marxism of collective action with respect to how exploitation is to be understood, which suggest that the intellectual current is not as homogeneous as Lash and Urry imply. Moreover, the paper stresses that the differences between them with regard to exploitation are more than just unhelpful disagreements over matters of definition, but represent fundamental disagreements about the validity of Marx's original formulations in contemporary society.
