Sample Age

Evolutionary biologists have long considered menopause to be a fundamental puzzle in understanding human fertility behaviour, as post-menopausal women are no longer physiologically capable of direct reproduction. Menopause typically occurs between 45 and 55 years of age, but across cultures and history, women often stop reproducing many years before menopause. Unlike age at first reproduction or even birth spacing, a woman nearing the end of her reproductive cycle is able to reflect upon the offspring she already has—their numbers and phenotypic qualities, including sexes. This paper reviews demographic data on age at last birth both across and within societies, and also presents a case study of age at last birth in rural Bangladeshi women. In this Bangladeshi sample, age at last birth preceded age at menopause by an average of 11 years, with marked variation around that mean, even during a period of high fertility. Moreover, age at last birth was not strongly related to age at menopause. Our literature review and case study provide evidence that stopping behaviour needs to be more closely examined as an important part of human reproductive strategies and life-history theory. Menopause may be a final marker of permanent reproductive cessation, but it is only one piece of the evolutionary puzzle.

Identity Based

Recent academic research highlights the role of leadership identity when thinking about the improvement of the educational field. Based on this research, this article aims to identify and analyze the elements that affect the development of leadership identity in female school principals within the Chilean context. This is achieved by working from a biographical-narrative approach, specifically from the life history technique. This analysis emerges from a considerate reflection on the teachings, and personal and professional milestones highlighted in the biogram. Both personally and professionally, a multiplicity of elements is observed in the life history of María Eliana, influencing the development of her leadership identity, particularly highlighting her self-recognition as a woman. This identity is oriented towards social justice, based on socio-emotional tools such as care, empathy, and participation; and understands and values the role these elements must take in Chilean education. The case study presents tensions for the Chilean educational system, which must be able to address the complexities that women experience while holding leadership positions, especially when challenged with the perspective that school is an inclusive space of social justice.

History Approach

Recent extensions to life history theory posit that exposure to environmental unpredictability during childhood should forecast negative parental behaviors in adulthood. In the current research, this logic was extended to co-parental behaviors, which refer to how parents coordinate, share responsibility, and support each other’s parental efforts. The effects of early-life unpredictability on individual and dyadic co-parental functioning were examined in a sample of 109 families (two parents and their firstborn child) who were followed longitudinally from before the child’s birth until the age of two. Greater early-life unpredictability (family changes, residential changes, and parents’ occupational changes by age 8) experienced by mothers, but not fathers, predicted more negative co-parental behaviors in triadic observations 6 months post birth, and lower couple-reported co-parenting quality assessed 3, 9, 18, and 24 months post birth. These effects were not explained by parents’ childhood socioeconomic status or current relationship quality. These findings highlight the role of mothers in shaping co-parenting relationships and how these relationships might be influenced by mothers’ early-life experiences.
