We also show that the effect of menses on migraine days varies more within-woman than between-women. This work provides an initial foundation for better understanding menstrual-related migraine from the perspective of the individual patient. This study supports previous research and demonstrates that the odds of migraine days are elevated from day -2 to day +3 of the menstrual cycle. We also show that the effect of menses on migraine days varies more within-woman than between-women. This work provides an initial foundation for better understanding menstrual-related migraine from the perspective of the individual patient.Three hundred and ninety-one children (195 girls; Mage = 9.56 years) attending Grades 1 and 5 completed implicit and explicit measures of math attitudes and math self-concepts. Math grades were obtained. Multilevel analyses showed that first-grade girls held a strong negative implicit attitude about math, despite no gender differences in math grades or self-reported (explicit) positivity about math. The explicit measures significantly predicted math grades, and implicit attitudes accounted for additional variance in boys. The contrast between the implicit (negativity for girls) and explicit (positivity for girls and boys) effects suggest implicit-explicit dissociations in children, which have also been observed in adults. Early-emerging implicit attitudes may be a foundation for the later development of explicit attitudes and beliefs about math. Afro hair breakage is most commonly attributed to grooming practices such as braiding, hair extensions and weaves, both for chemically treated hair and natural Afro hair. These grooming practices are also frequently associated with traction alopecia in clinical studies. However, there is little to no quantitative scientific data on the surface and internal hair fibre damage caused by grooming, including co
