This article reports the results of a study of registered nurses working with adults with an intellectual disability and challenging behaviour. The purpose of the research was to describe the participants' emotional response to violence and to explore what support they require in dealing with constant exposure to workplace violence. This study has highlighted that working with individuals with an intellectual disability and challenging behaviour is an emotionally distressing job due to the constant anxiety related to the anticipation of violence. The literature review supports the findings that nurses working in the field of intellectual disability are subjected to a greater number of violent incidents than other fields of nursing. The findings of the study married aptly with Howard and Hegarty's (2003) study. The main support staff received was from within their immediate work environment, which had a buffering effect on their levels of stress. Registered nurses who work in the field of intellectual disability and challenging behaviour are the greatest resource and asset of the organisation and improving their wellbeing will be reflected in the care clients receive.

Purpose: The purpose of this paper is to capture the stories of earthquake experiences from one community and relate this material to some of the psychological phases of recovery from a disaster. Design/methodology/approach: The approach taken was qualitative, explorative and participatory. The researchers were partners in the school project, as the school determined its own methodology, participation and end result. The audio or video interviews were open-ended and explored broad themes, in groups and individuals. Participants included multiple members of the same families. The stories of the participants were used to illustrate the psychological phases of recovery. Findings: The experiences of the research participants were reviewed through the psychological phases of recovery highlighted in the literature (e.g. Myers and Zunin, 2000). The phases identified in the stories indicate that the Christchurch situation is consistent with international experience. Additional psychological responses such as community bonding and resilience, as well as living with secondary stressors, were also identified. Research limitations/implications: There are some commonalities apparent for this group of interviewees, for example, many were together at the school, at the time of the 22 February 2011 earthquake. However, there are also many differences and unique experiences and as such, only tentative generalisations can be made from these interviews. Originality/value: The paper contributes to the wider collection of research on and about the Canterbury earthquakes by discussing elements of psychological recovery through the experiences of one community of parents, teachers and primary school children. © Emerald Group Publishing Limited.

In Computer Engineering 2b, one of the Level 7 courses in the Bachelor of Engineering Technology programme offered at Christchurch Polytechnic Institute of Technology, a "real world" project is always used as assignments for teaching and assessment. In the recent years, one of these assignments is to implement the ZigBee protocol in the in-house developed microcontroller training kit. Involving emerging technologies of the wireless sensor control network in the assignment has stimulated students' interest, not only in embedded systems but also in other areas such as wireless communications. © 2011 IEEE.

Objectives: The aim of this study was to examine the effects of hemolysis, rapid chilling, time, and the addition of a maleimide on the stability of human plasma ACTH measurements. Design and methods: Partially hemolyzed EDTA blood (n=10), initially at 37 °C, was centrifuged at 4 °C either immediately or after rapid chilling in ice/water. Plasma ACTH was then measured either immediately, or after 1. h at 22°C with or without the addition of 2. mM N-phenyl maleimide (NPM). Results: For 0.2% hemolysis compared to no hemolysis, the mean (±SEM) loss with immediate centrifugation and immediate ACTH measurement was 11± 1%. This loss was significantly (p<0.002) reduced to 6 ±1% by an initial rapid chilling of the samples. For analysis after 1. h at 22°C, the addition of NPM decreased the loss of ACTH from 15±2% to 2±2% (p<0.002). Conclusion: Rapid chilling, prompt analysis, and addition of NPM can each reduce the interference of hemolysis in the measurement of plasma ACTH concentrations. © 2010 The Canadian Society of Clinical Chemists.

Background and aims: Although the nutrient enrichment literature emphasises anthropogenic sources, seabirds deposit large quantities of marine detritus at breeding and roosting sites. Little is known of the chemical fractions and plant availability of seabird soil nutrients and their relationship to nutrient limitation patterns.Methods: Nutrients in mineral soil from a breeding colony of burrowing seabirds were progressively depleted by growing radiata pine (Pinus radiata D. Don.) and wheat (Triticum aestivum) separately in small pots over 4–10 months. Soil from destructively sampled pots was analysed using a version of the Hedley fractionation scheme; foliage was analysed for C, N and δ15N using isotope ratio mass spectrometry, and for P using microwave assisted digestion and ICP-OES.Results: Foliar C:N and δ15N increased with plant mass for both species, but N:P remained constant within plants of each species. As total soil P was progressively depleted, concentrations of bicarbonate-extractable soil P were maintained. This occurred mainly by depletion of non-labile inorganic P forms, thus demonstrating potential mobilisation of all refractory P (as defined by our chemical fractionation method) into plants growing at the seabird site. The increasing foliar δ15N was consistent with the progressive mobilisation of more highly recycled forms of N.Conclusions: We infer a species-specific stoichiometric homeostasis for N and P in plants grown in seabird soil, facilitated by mobilisation of recalcitrant forms of soil N and P. © 2014, Springer International Publishing Switzerland.

This study investigated the role of the invasive mallow Lavatera arborea in the terrestrial ecosystem of a flourishing seabird island in SE New Zealand using natural abundance stable isotope ratios (13C/12C; 15N/14N, reported as δ13C and δ15N). Foliage samples of L. arborea came from transects encompassing three distinct environments (plateau, slope, storm-washed flat) across the island. Samples of potential marine nutrient sources (beach-cast kelp; seabirds using the island) were also collected, to contextualise the L. arborea data. Samples of invertebrate taxa (exotic and indigenous) from multiple ecosystem guilds were hand-collected; a bee, a sap-sucking Homoptera, a litter-feeding tenebrionid beetle, various carrion-feeding flies, a predatory carabid beetle, a salticid spider, and (from a seabird cadaver) Dermestes sp. exuviae. Discarded skins from the gecko Hoplodactylus maculatus were collected from moulting sites. Highly enriched δ15N values showed that L. arborea from all three environments utilised seabird N, even though breeding seabirds were absent from the storm-washed flat. The isotopic signatures of the Homoptera, and the tenebrionid and carabid beetles could be accounted for entirely by food webs based on L. arborea. Bee and salticid spider isotopic signatures could be accounted for by varying contributions from L. arborea. The flies and Dermestes were (as expected) linked to carrion from either the island or the adjacent mainland. In contrast, gecko data indicated direct dependence on seabirds, although the exact relationship was unclear. Our study therefore showed that L. arborea is an integral part of the terrestrial ecosystem of the island across multiple trophic levels from pollinators to top-level predators. © Springer Science+Business Media B.V. 2009.

This exploratory study tested the hypothesis that petrels (Aves: Procellaridae) actively plough the soil of their entire breeding colonies, as implied by their well-known burrowing capabilities but contra-indicated by widespread horizonation in colony soil. Two profiles to lithic contact were excavated within a forested Westland petrel (Procellaria westlandica) colony; one, a ridgeline control without nearby petrel burrows, and the other from a steep slope among petrel burrows. On the ridgeline, 137Cs activities (estimated per volume) steadily decreased with depth as expected. At the burrowed site, a subsurface maximum at 12-16 cm depth indicated a post-1963 burrowing or landslip event. Both 210Pb profiles were successfully modelled (r2 c. 0.9) using a simple first-order model usually applicable only to undisturbed soils. In this model, mixing is accounted for by radioactive decay and first-order, mm-scale biodiffusion. The results therefore indicated that soil mixing was not dominated by petrel burrowing; rather, petrels confine their burrowing activities to maintenance of their burrows as semi-permanent (decades to centuries) structures. However, further sampling is recommended to confirm this view. © 2010 The Royal Society of New Zealand.

A research project to examine the theoretical and practical exposure student nurses have to Primary Health Care (PHC) and community nursing in their undergraduate programme was undertaken in New Zealand (NZ). Providing quality clinical placements for health care students is acknowledged as a major challenge for tertiary institutions. In order to reflect the current shift in health care delivery from hospital to community settings, one such challenge is to ensure students receive appropriate theoretical programme content and clinical experience in PHC and community settings. The project consisted of a review of relevant international literature, and a questionnaire sent to all NZ tertiary institutions providing a Bachelor of Nursing (BN). Findings included a variable understanding of the concept of PHC, a lack of appropriate PHC placements across the country, competition for student placements in PHC, and professional organisation requirements for student supervision impacting on placement availability. Innovations identified to increase PHC placements comprised the establishment of Dedicated Education Units (DEUs), curriculum revision, and final year PHC placements offered only to students targeting PHC settings on registration. Study recommendations involve establishing a regional rather than a local approach to managing clinical placements, increasing professional governance support and reviewing clinical placement funding. © 2012 Elsevier Ltd.
