What does it mean to “be in a mood” at school? This question guides this thesis, which analyses the relationship between young people’s experiences of moods and the discourses and pedagogies of moods they encounter at school. The emotions and moods of young people in Christchurch, New Zealand, have, in recent years, come under considerable scrutiny. A national decline in rates of youth mental health and concern over the lasting psychological effects of the 2010-2011 Christchurch Earthquakes have justified increased attention to and funding for youth mental health promotion and school-based mental health education programs. Drawing on a year-long school ethnography at a public girl’s high school in Christchurch with 22 Year 10 students (age 14-15), this thesis examines how young people interact with state and psychiatric discourses of youth and mental health. It explores how young people integrate and transform these discourses in their experiences and knowledges of moods as they relate to mental health, education, friendships, and the (in)stability of the self in time. Additionally, this thesis proposes an anthropological reconsideration of moods. Developing insights from phenomenological and medical anthropology and bringing them into conversation with ethnographic analysis, the approach to moods in this thesis sees two necessarily interconnected ways in which moods become significant for understanding subjectivity and contemporary society. On the one hand, moods are an integral dimension of phenomenological experience in which it is possible to dwell in affective ambiguities, producing open-ended horizons of experience. On the other hand, young people’s experience of moods is refracted through moods’ medicalised formulation as experience that can be bounded, taxonomized, transformed into kinds of knowledge about the self, and thus acted on in distinct and morally situated ways. Attending to the experience of “being in a mood” at school reveals how medical and psychiatric knowledges are woven into moral experience in the everyday. This moral experience of moods has critical implications for how young people in New Zealand today situate the self in relationships, in the world, and in time, and therefore is particularly revealing for developing anthropological understandings of teenage subjectivity

Tree mortality is a fundamental process governing forest dynamics, but understanding tree mortality patterns is challenging because large, long-term datasets are required. Describing size-specific mortality patterns can be especially difficult, due to few trees in larger size classes. We used permanent plot data from Nothofagus solandri var. cliffortioides (mountain beech) forest on the eastern slopes of the Southern Alps, New Zealand, where the fates of trees on 250 plots of 0.04 ha were followed, to examine: (1) patterns of size-specific mortality over three consecutive periods spanning 30 years, each characterised by different disturbance, and (2) the strength and direction of neighbourhood crowding effects on sizespecific mortality rates. We found that the size-specific mortality function was U-shaped over the 30-year period as well as within two shorter periods characterised by small-scale pinhole beetle and windthrow disturbance. During a third period, characterised by earthquake disturbance, tree mortality was less size dependent. Small trees (,20 cm in diameter) were more likely to die, in all three periods, if surrounded by a high basal area of larger neighbours, suggesting that sizeasymmetric competition for light was a major cause of mortality. In contrast, large trees ($20 cm in diameter) were more likely to die in the first period if they had few neighbours, indicating that positive crowding effects were sometimes important for survival of large trees. Overall our results suggest that temporal variability in size-specific mortality patterns, and positive interactions between large trees, may sometimes need to be incorporated into models of forest dynamics.
