The Individual

This article offers an analysis of the identity work of a black transgender woman through life history research. Identity work pertains to the ongoing effort of authoring oneself and positions the individual as the agent; not a passive recipient of identity scripts. The findings draw from three life history interviews. Using thematic analysis, the following themes emerge: institutionalisation of gender norms; gender and sexuality unintelligibility; transitioning and passing; and lastly, gender expression and public spaces. The discussion follows from a poststructuralist conception of identity, which frames identity as fluid and as being continually established. The study contends that identity work is a complex and fragmented process, which is shaped by other social identities. To that end, the study also acknowledges the role of collective agency in shaping gender identity.

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.

The life history of B. mackini was studied in a large argillotrophic lake during 1970–1972. Hatching began immediately after spring thaw and was terminated by rising salinity 10 days to 2 weeks later. Growth rates reached maxima of 1 mm/day at 4 weeks of age and then declined as mean size approached 22–23 mm at 7–8 weeks. Clutch sizes varied as a function of female length. Maximum biomass of 580 mg dry weight/m2 (2700 cal/m2) was reached in late May, of which 3.9% per day was consumed by B. gigas. Source of the energy is presumed to be a bacteria – organic matter complex associated with suspended particles. Life cycle details are compared with other fairy shrimp species and the role of B. mackini in the community is discussed.
