title: Bottom sediments of lake rotoma

authors: Nelson, Campbell S.

subjects: Lake Rotoma

abstract: Lake Rotoma is a deep (70–80 m), oligotrophic, warm monomictic lake of volcanic origin with insignificant stream inflow and no clearly defined outflow. For at least 60 years up to 1972 the lake level fluctuated markedly about an overall rising trend of some 6–10 m. Nearshore profiles are related to the prevailing wave climate superimposed upon the overall rising lake level, shelves being wider, less steep, and deeper about the more exposed eastern and southern shorelines. The outer portions of shelves extending well below modern storm wave base into waters as deep as 15–25 m are relict features from lower lake level stands. Sediments fine from sand‐gravel mixtures nearshore to silts in basinal areas. Their composition reflects a composite provenance involving the lavas and tephras about the lake, as well as intralake diatom frustules and organic matter. The distribution pattern of surficial bottom sediments is an interplay between grains of both biological and terrigenous origin, supplied presently and in the past by a variety of processes, that have been dispersed either by the modern hydrodynamic regime or by former ones associated with lower lake levels. These interrelationships are structured by erecting 5 process‐age sediment classes in the lake, namely neoteric, amphoteric, proteric, palimpsest, and relict sediments, analogous to categories postulated for sediments on oceanic continental shelves. Short‐core stratigraphy includes the Kaharoa (A.D. ∼ 1020) and Tarawera (A.D. 1886) tephras. The rates of sedimentation of diatomaceous silts in basinal areas have more than doubled since the Tarawera eruption, indicating an overall increase in the fertility level of lake waters associated, perhaps, with recent farm development in the catchment. © 1983 Taylor & Francis Group, LLC.

title: Becoming smaller: Autobiographical spaces of weight loss

authors: Longhurst, Robyn

subjects: fat

abstract: This research focuses on the spaces and politics of weight loss. It is informed by “fat studies”, critical geographical scholarship on fat, and two contrasting feminist readings of Michel Foucault's notion of “care of the self”. Using autobiography as a method of inquiry I share my experience of “becoming smaller” through weight loss dieting. I argue that losing weight for me has been paradoxical on at least three counts: first, by being a feminist scholar who critiques discourses around women and slimness while at the same time desiring to be slim; second, by my new eating patterns marking me simultaneously as both a disciplined and a disordered subject; and third, by publically and politically supporting the Health at Every Size movement but privately in my “quest” to recreate myself emphasizing shedding kilos over fitness. The article concludes that understanding these paradoxes that surround weight loss is useful for furthering understanding of a complex embodied, gendered and spatialized process.

title: The enowning of thought and whakapapa: Heidegger's fourfold

authors: Mika, Carl Te Hira

subjects: Maori

abstract: Throughout colonization, Maori have been constantly urged to think of their terminology, and the objects it relates to, along constrained lines. In this practice, the self and other things are arguably restricted and impoverished. However, certain frequently used Maori terms – such as “whakapapa” and “whakaaro” – may be read alongside Heidegger’s “Ereignis,” revealing a completely other sense to them than their orthodox, respective translations of “genealogy” and “to think” allow. This kind of thinking in concert with an existential philosophy is an active process that allows for the “freeing up” of entities and a colonized group. With Heidegger’s assistance, the terms, and the original sources they refer to, reflect a kind of “Geviert”/Fourfold that ensures a continual strife and interplay between things in the world and self.
