This paper examines gender diversity in sport governance globally. Theoretically, the study draws on gender dynamics in organisations, in particular on Kanter's concepts of gender ratios and critical mass. An audit of the gender ratio on boards of National Sport Organisations ( n = 1,600) was conducted in 45 countries. Data were collected through the Sydney Scoreboard, an interactive website that tracks women's presence on sport boards internationally. Findings show that women remain under-represented on three key indicators: as board directors (global mean 19.7 %), board chairs (10.8 %) and chief executives (16.3 %). Few countries have achieved a critical mass of 30 % representation and no continent has achieved the critical mass on any of the three indicators. Women's under-representation in sport governance is due to complex gender dynamics. Gender diversity on sport boards is associated with four interwoven dimensions of gender relations: production, power, emotion and symbolism. The combination of the four dimensions produces an environment that may or may not be conducive to gender diversity. [ABSTRACT FROM AUTHOR]

An experiment was conducted to examine the impact of media gender ratios on male audience members. One hundred thirty young adult men read a series of media narratives featuring either multiple men and a single woman or multiple women and a single man as well as a measure of endorsement of traditional masculinity and measures of romantic and sexual selectivity and confidence. Men who read the abundant partners narratives exhibited greater selectivity for marriage partners relative to control participants. Partner availability or scarcity in media narratives also influenced romantic confidence, although this was moderated by endorsement of traditional masculine ideology (TMI). [ABSTRACT FROM AUTHOR]

If parties nominate both male and female candidates, open-list PR electoral rules enable voters to engage in same-gender voting (i.e. select candidate of the same gender). In this regard, there is a gender gap in Finland, an otherwise highly egalitarian country: over time, men tend to support mostly male candidates, while women are roughly equally divided between male and female candidates. This study investigates whether voters' likelihood of selecting a candidate of the same gender is affected by contextual factors. Based on pooled cross-sectional data from five Finnish parliamentary elections between 1979 and 2011, it shows that gender differences in same-gender voting are substantially reduced when district magnitude and gender ratios among candidates and elected deputies are taken into account.

This study examined whether boys and girls in the early school years differed in reading and related skills, and their rates of progress. Gender ratios were calculated to ascertain whether there were more boys than girls who struggle with different facets of reading, and whether the variability of boys’ scores resulted in more boys being identified as poor readers, as evidenced by previous studies. A sample of 335 students in Years 1 and 2 were administered six reading and related assessments. Boys and girls did not significantly differ on any of the measures, and differences in gains were negligible. Boys did not consistently demonstrate significantly greater variability in scores (with the exception of single-word reading and spelling in Year 1 only). These differences, however, did not affect gender ratios for poor performance. Gender ratios were relatively low across measures, but increased with years of schooling. Implications of the results are discussed. [ABSTRACT FROM PUBLISHER]

Background: In order to fully specify the profiles of risk and protective factors of developmental disorders, a better understanding of the conditions under which they co-occur is required. So far, empirical evidence on comorbidities of specific learning disorders in arithmetic, reading and spelling is scarce. Methods: Prevalence and gender ratios of specific learning disorders in arithmetic (AD), reading (RD), and spelling (SD) and their co-occurrence were assessed in a large ( N = 2586) population-based sample of elementary school children and in a subsample of 293 children with at least one learning disorder (LD-sample). A questionnaire on familial transmission was given to a subsample of 256 parents of children with a learning disorder and 146 typically developing children. Results: The rates of deficits in arithmetic, reading, or spelling were four to five times higher in samples already experiencing marked problems in one academic domain compared to the full population. Thus, comorbidity of learning disorders was confirmed in a fairly standard school population. Rates of co-occurrence decreased for AD and RD, but not isolated SD when more stringent cutoff criteria were applied, suggesting that the comorbidity of arithmetic and spelling disorder may be more strongly biologically mediated than the comorbidity of arithmetic and reading disorder. We found a preponderance of girls with AD and boys with SD. These imbalanced gender ratios were especially marked for isolated problems, while for comorbid problems gender ratios were mostly balanced with the exception of deficits in arithmetic and reading (but not spelling) which were more typical for girls. The parental questionnaire provided evidence for disorder-specific familial transmission and co-segregation of arithmetic and literacy deficits. Conclusions: Comorbidities of learning disorders are not artificial. They are the result of a complex interplay between both general and disorder-specific aetiological factors.

Despite an expanding epidemiological evidence base, uncertainties remain over key aspects of the epidemiology of the ‘antisocial’ disorders in childhood and adolescence. We used cross-sectional data on a nationally representative sample of 10,438 5–15-year-olds drawn from the 1999 British Child Mental Health Survey to examine age trends, gender ratios and patterns of comorbidity in DSM-IV Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD). CD was significantly more common in boys than girls, and increased in prevalence with age. Among children who met diagnostic criteria for CD, status violations and other non-aggressive conduct problems increased with age, while aggressive symptoms became less common. Gender differences in ODD varied by reporter. Estimates of age trends in ODD depended heavily on treatment of overlaps with CD. Following DSM-IV guidelines (where ODD is not diagnosed in the presence of CD), rates of ODD fell with age; if that constraint was released, clinically significant rates of oppositionality persisted at similar levels from early childhood to middle adolescence. CD and ODD showed high levels of overlap, and both diagnoses showed substantial comorbidity with other non-antisocial disorders. Results from this large-scale study confirm and extend previous findings in the epidemiology of the disruptive behaviour disorders. [ABSTRACT FROM AUTHOR]

Since 2001, gender convergence in risky drinking in Australia has been evident only in people aged 50–69 years. However, reports of significant change in gender ratios provide little information about interesting changes within genders. [ABSTRACT FROM AUTHOR]
