Latina and European American Girls’ Experiences with Academic Sexism and their Self-Concepts in Mathematics and Science During Adolescence

The study investigated Latina and European American adolescent girls’ (N = 345, M = 15.2 years, range = 13 to 18) experiences with academic sexism in mathematics and science (M/S) and their M/S perceived competence and M/S value (liking and importance). M/S academic sexism was based on girls’ reported experiences hearing sexist comments about girls’ abilities in math and science. Older European American adolescents, and both younger and older Latina adolescents, who experienced several instances of academic sexism felt less competent in M/S than girls who experienced less sexism (controlling for M/S grades). In addition, among older girls (regardless of ethnicity), those who experienced several instances of academic sexism valued M/S less than girls who experienced less sexism

Associations between meteorological variables and acute stroke hospital admissions in the west of Scotland

Background - We combined a large clinical stroke registry with the UK Met Office database to assess the association between meteorological variables and specific clinical subtypes of acute stroke. Methods - We used negative binomial regression and Poisson regression techniques to explore the effect of meteorological values to hospital with acute stroke. Differential effects of atmospheric conditions upon stroke subtypes were also investigated. Results - Data from 6389 patients with acute stroke were examined. The mean age (SD) was 71.2 (13.0) years. About 5723 (90%) patients suffered ischaemic stroke of which 1943 (34%) were lacunar. Six hundred and sixty-six patients (10%) had haemorrhagic stroke. Every 1 degrees C increase in mean temperature during the preceding 24 h was associated with a 2.1% increase in ischaemic stroke admissions (P = 0.004). A fall in atmospheric pressure over the preceding 48 h was associated with increased rate of haemorrhagic stroke admissions (P = 0.045). Higher maximum daily temperature gave a greater increase in lacunar stroke admissions than in other ischaemic strokes (P = 0.035). Conclusion - We report a measurable effect of atmospheric conditions upon stroke incidence in a temperate climate

Empowering women: the role of emancipative forces in board gender diversity

This study investigates the effect of countrylevel emancipative forces on corporate gender diversity around the world. Based on Welzel’s (Freedom rising: human empowerment and the quest for emancipation. Cambridge University Press, New York, 2013) theory of emancipation, we develop an emancipatory framework of board gender diversity that explains how action resources, emancipative values and civic entitlements enable, motivate and encourage women to take leadership roles on corporate boards. Using a sample of 6390 firms operating in 30 countries around the world, our results show positive single and combined effects of the framework components on board gender diversity. Our research adds to the existing literature in a twofold manner. First, our integrated framework offers a more encompassing, complete and theoretically richer picture of the key drivers of board gender diversity. Second, by testing the framework empirically, we extend the evidence on national drivers of board gender diversity
