RESUMEN
COVID-19 forced the digitalisation of teaching and learning in a response often described as emergency remote teaching (ERT). This rapid response changed the social, spatial, and temporal arrangements of higher education and required important adaptations from educators and students alike. However, while the literature has examined the constraints students faced (e.g. availability of the internet) and the consequences of the pandemic (e.g. student mental health), students' active management of these constraints for learning remains underexplored. This paper aims to "think with" COVID-19 to explore student agency in home learning under constrained circumstances. This qualitative study used semi-structured interviews to understand the day-to-day actions of nineteen undergraduate students managing their learning during the COVID-19 lockdowns in Victoria, Australia. Emirbayer and Mische's multiple dimensions of agency - iterative, projective, and practical-evaluative - are used to explore student experience. The findings illustrate students' adaptability and agency in navigating life-integrated learning, with most of their actions oriented to their present circumstances. This practical evaluative form of agency was expressed through (1) organising self, space, time, and relationships; (2) self-care; and (3) seeking help. Although this study took place in the context of ERT, it has implications beyond the pandemic because higher education always operates under constraints, and in other circumstances, many students still experience emotionally and materially difficult times.
RESUMEN
The neuroendocrine response of female sheep to a novel male involves neural activation in the hypothalamus. However, if males are removed, the gonadotrophic signal declines, so the neural activity is likely to change. We examined Fos-immunoreactive (IR) cells in hypothalamic tissues from seasonally anovulatory female sheep exposed to males for 2 or 6h, or for 2h followed by 4h isolation from males. Control females were killed in the absence of male exposure. Male introduction increased LH secretion in all females; male removal was associated with a reduction only in mean and basal LH concentrations. Females exposed to males for 2h had more Fos-IR cells in the arcuate nucleus (ARC), ventromedial nucleus of the hypothalamus (VMH) and organum vasculosum of the lamina terminalis (OVLT) than control females. Fos-IR cells in the preoptic area (POA) were only greater than in control females after 6h exposure to a male. Removal of males decreased the number of Fos-IR cells in the ARC, VMH and OVLT, but not in the POA. Thus, hypothalamic neural activation and LH secretion in female sheep are stimulated by males and decline after male removal. However, activation in the POA persists after removal and may explain the incomplete decline in the LH response.
