We quantitatively reviewed human sex differences in the magnitude and variability of duration judgments. Data from 4,794 females and 4,688 males yielded 87 effect size estimates of magnitude and 28 of variability. The overall sex difference in duration judgment magnitude was small but statistically significant. It was moderated by whether study participants knew in advance (prospective paradigm...

OBJECTIVE To assess the availability and quality of population size estimations of female sex workers (FSW), men who have sex with men (MSM), people who inject drug (PWID) and transgender women. METHODS Size estimation data since 2010 were retrieved from global reporting databases, Global Fund grant application documents, and the peer-reviewed and grey literature. Overall quality and availabi...

The aim of this study was to estimate the rates of recovery, treatment-seeking, and natural recovery from pathological gambling (PG) in men and women in a community-based national survey, and to examine the role of gambling problem recognition in recovery from PG. Participants were 4,764 individuals from a community-based Australian national twin registry (104 with a lifetime history of PG) who...

Strength of lateralization for processing facial emotion becomes more right hemisphere lateralized throughout childhood, but sex differences in this development are not currently understood. This study examines patterns of lateralization for emotion discrimination in 185 6-10-year-olds. Strength of right hemisphere lateralization was stronger in the older children, and right hemisphere dominanc...

Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering "feminised" re-framings of anti-abortion arguments, this p...

OBJECTIVE To evaluate the effect of patients' sex on selection of pacemakers. DESIGN Retrospective univariate and multivariate analysis of a large database. SETTING German central pacemaker register. SUBJECTS Records collected at the register for 1992 and 1993 (n=31 913), covering 64% of all implantations in Germany. MAIN OUTCOME MEASURE Probability of receiving a single chamber, dual c...

Sex determination in honeybees involves a multi-allelic locus, such that homozygotes develop as males and heterozygotes as females. In this issue of Cell, report the cloning of the sex-determining gene, csd. It codes for an SR protein, and different alleles have very different amino-acid sequences. Inactivating csd leads to development as a male.

This study examined sex differences in money beliefs and behaviours. Over 100,000 British participants completed two measures online, one of which assessed "money pathology" (Forman in Mind over money, Doubleday, Toronto, 1987), and the other four "money types", based on the emotional associations of money (Furnham et al. in Personal Individ Differ, 52:707-711, 2012). Nearly all measures showed...

The purpose of the present study was to determine sex differences in facial, prosodic, and social context emotional recognition in schizophrenia (SCH). Thirty-eight patients (SCH, 20 females) and 38 healthy controls (CON, 20 females) participated in the study. Clinical scales (BPRS and PANSS) and an Affective States Scale were applied, as well as tasks to evaluate facial, prosodic, and within a...

A review of published reports showed that the sex ratio (proportion of boys) was low among infants conceived after ovulation had been induced. The difference between the observed sex ratio and an expected one of 0 . 514 was highly significant. These findings suggest that maternal gonadotrophin concentrations at the time of conception directly affect the sex of the zygote.
