title: Non-suicidal self-injury in a New Zealand student population: Demographic and self-harm characteristics

authors: Fitzgerald, John

subjects: Non-suicidal self-injury

abstract: There is an established international literature on the prevalence of non-suicidal self-injury (NSSI). However, New Zealand information regarding prevalence, attitudes, motivation, co-morbidities, etc., is limited. In this study data were collected using an on-line survey from approximately 850 university students regarding self-injurious behaviour, risk and protective factors, mental health co-morbidity, help-seeking, and addiction. Our data revealed that 293 participants (38%) had engaged in NSSI on at least one occasion in their lifetime, elevated risk for females who were lesbian or bisexual, and different patterns of site and function of injury by gender. Given research suggesting that Māori (indigenous New Zealanders) are at elevated risk for suicide it was surprising that those identifying as Māori were at no greater risk of NSSI than those identifying as New Zealanders of European origin. Females were more likely to exhibit chronic self-injuring and more likely to engage in more ‘covert’ forms of self-injury that can be hidden or disguised (e.g., scratching and cutting on their wrists, arms or thighs) whereas males were more likely to engage in ‘overt’ forms of self-injury (e.g., banging or punching themselves or objects with their hands or head). Patterns of NSSI were similar to international comparisons, although prevalence was somewhat elevated. A number of factors differed by gender, including underlying reasons, forms, rates and increasing severity of self-injury, which add to the international literature.

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: The waters of the Maori: Maori law and state law

authors: Durie, Edward Taihākurei

abstract: This paper is for filing in the Waitangi Tribunal in relation to a claim that existing laws do not adequately accommodate the Māori proprietary interest in natural, water resources. The claim was initiated by the New Zealand Māori Council in association with ten tribal groups. It was later accompanied by 166 other Māori groups, whom the Tribunal joined as interested parties.
