AbstractFrom 4 September 2010 on, a series of earthquakes shattered New Zealand for more than one year the most devastating of which caused the Canterbury TV (CTV) building in downtown Christchurch to collapse on 22 February 2011. One hundred and fifteen people were killed. A Royal Commission found out that, in 1986, the Christchurch City Council (CCC) had granted a building permit despite concerns about structural design issues. Moreover, the authority did not insist on structural analyses of the building after the initial earthquake of 4 September 2010. Thorough investigations after the disaster of 22 February 2011 revealed that the early concerns about insufficient joints between floors and shear walls had been entirely justified since the failure of the joints, according to all likelihood, had triggered the collapse of the building.

The recently published New Zealand Code of Practice for the Design of Concrete Structures (NZS 3101:1982) and the newly amended Code of Practice for General Structural Design and Design Loadings for Buildings (NZS 4203) permit a variety of possible design approaches for reinforced concrete shear wall structures. A series of wall designs for dimensionally similar four-storey and eight-storey buildings has been carried out and a comparison of construction cost estimates obtained together with an assessment of the relative design effort required for the different design options.

The Impact

Abstract In this paper, an evaluation was tried for the impact of structural design on structural response. Several situations are foreseen as the possibilities of changing the distribution of the structural elements (sails, columns, etc.), the width of the structure and the number of floors indicates the adapted type of bracing for a given structure by referring only to its Geometric dimensions. This was done by studying the effect of the technical design of the building on the natural frequency of the structure with the study of the influence of the distribution of the structural elements on the seismic response of the building, taking into account of the requirements of the Moroccan earthquake regulations 2000/2011 and using the ANSYS APDL and Robot Structural Analysis software.

The Impact

Abstract The objective of this study was to investigate the impact of the ewe’s maternal genetic merit and country of origin (New Zealand or Ireland) on ewe reproductive, lambing and productivity traits. The study was performed over a four year period (2016 to 2019) and consisted of three genetic groups: high maternal genetic merit New Zealand (NZ), high maternal genetic merit Irish (High Irish) and low maternal genetic merit Irish (Low Irish) ewes. Each group contained 30 Suffolk and 30 Texel ewes, selected based on the respective national maternal genetic indexes; i.e. either the New Zealand Maternal Worth (New Zealand group) or the €uro-star Replacement index (Irish groups). The impact of maternal genetic merit on reproductive traits such as litter size; lambing traits such as gestation length, birth weight, lambing difficulty, mothering ability, and productivity traits such as the number of lambs born and weaned were analyzed using linear mixed models. For binary traits, the impact of maternal genetic merit on reproductive traits such as conception to first AI service; lambing traits such as dystocia, perinatal lamb mortality and productivity traits such as ewe survival were analyzed using logistic regression. New Zealand ewes outperformed Low Irish ewes for conception to first AI (P<0.05) and litter size (P=0.05). Irish ewes were more likely to suffer from dystocia (6.84 (High Irish) and 8.25 (Low Irish) times) compared to NZ ewes (P<0.001); birth weight and perinatal mortality did not differ between groups (P>0.05). Lambs born from NZ ewes were 4.67 (95% CI: 1.89 to 11.55; P<0.001) and 6.54 (95% CI: 2.56 to 16.71; P<0.001) times more likely to stand up and suckle unassisted relative to lambs born from High or Low Irish ewes, respectively. New Zealand and High Irish ewes had a greater number of lambs born and weaned throughout the duration of the study compared to their Low Irish counterparts (P<0.001). New Zealand ewes tended to be more likely to survive from one year to the next compared to Low Irish ewes (P=0.07). Irish ewes of high maternal genetic merit outperformed their Low counterparts in total number of lambs born and weaned per ewe, but performance did not differ across other traits investigated. This highlights the importance of continuous development of the Irish maternal sheep index to ensure favourable improvements in reproductive, lambing and productivity traits at farm level. Overall, results demonstrate the suitability of NZ genetics in an Irish production system.

Maori Health

Māori are the indigenous people of New Zealand, and suffer disparate health outcomes compared to non-Māori. Waikato District Health Board provides level III intensive care unit services to New Zealand’s Midland region. In 2016, our institution formalised a corporate strategy to eliminate health inequities for Māori. Our study aimed to describe Māori health outcomes in our intensive care unit and identify inequities. We performed a retrospective audit of prospectively entered data in the Australian and New Zealand Intensive Care Society database for all general intensive care unit admissions over 15 years of age to Waikato Hospital from 2014 to 2018 ( n = 3009). Primary outcomes were in–intensive care unit and in-hospital mortality. The secondary outcome was one-year mortality. In our study, Māori were over-represented relative to the general population. Compared to non-Māori, Māori patients were younger (51 versus 61 years, P < 0.001), and were more likely to reside outside of the Waikato region (37.2% versus 28.0%, P < 0.001) and in areas of higher deprivation ( P < 0.001). Māori had higher admission rates for trauma and sepsis ( P < 0.001 overall) and required more renal replacement therapy ( P < 0.001). There was no difference in crude and adjusted mortality in–intensive care unit (16.8% versus 16.5%, P = 0.853; adjusted odds ratio 0.98 (95% confidence interval 0.68 to 1.40)) or in-hospital (23.7% versus 25.7%, P = 0.269; adjusted odds ratio 0.84 (95% confidence interval 0.60 to 1.18)). One-year mortality was similar (26.1% versus 27.1%, P=0.6823). Our study found significant ethnic inequity in the intensive care unit for Māori, who require more renal replacement therapy and are over-represented in admissions, especially for trauma and sepsis. These findings suggest upstream factors increasing Māori risk for critical illness. There was no difference in mortality outcomes.

We investigate the relative weights of catch plans, expected profit, and traditions in fishers’ decision-making for five New Zealand fleets subject to an individual transferable quota (ITQ) management regime. Métiers were defined for these fleets as a combination of gears, management units, and a targeting index (either target species or statistical area). A nested logit random utility model was used to model the métier allocation of fishing effort in relation to catch plans, expected profit, and past fishing allocations. This study showed that traditions and catch plans appeared to be important determinants of fishers’ behavior for these New Zealand fleets. The model developed in this study fitted the data generally well and was also able to predict, in most cases, future effort allocation both one month and one year ahead.

This article examines the activities of the Freemans Bay Residents Welfare Association, which formed to promote residents’ welfare and to retain the neighbourhood’s integrity in the face of slum clearance during the 1950s and 1960s in Auckland, New Zealand. The Association’s objective was: ‘To combine socially for the cultural good of all people in the area. To unite as one, regardless of race, colour or creed, for the peaceful and fruitful existence of our residents.’ John (Johnny) James Mitchell, secretary of the Association, invoked working-class solidarity – to unite as one – to bring together residents who could also be classified by race, religion, political belief, employment status, ‘respectability’ and housing occupancy. This solidarity was assisted by the Auckland City Council who zoned the Reclamation Area for clearance, affecting all residents within its bounds. However, racial discrimination practised by private landlords, local government and state departments meant that Māori were more likely to occupy condemned housing to begin with and were the last to be assisted by the state in the slum clearance process. As a result, race remained a more potent signifier for Māori residents and they organised through the Māori Women’s Welfare League and the Māori Community Centre, in alliance with the Association.

Heritage Discourse

<p>Through a specific historical case study, Another Elderly Lady to be Knocked Down applies discourse theory and the Authorised Heritage Discourse (AHD) to the context of urban built heritage in Aotearoa New Zealand. Previously, only limited work had been done in this area. By examining an underexplored event this dissertation fills two gaps in present literature: the history of the event itself and identification of the heritage discourses in the country at the time. Examination of these discourses in context also allows conclusions about the use of the AHD in similar studies to be critically examined.  In 1986 the Missions to Seamen building in Wellington, New Zealand, was threatened with demolition by its government owners. In a remarkable display of popular sentiment, individuals, organisations, the Wellington City Council (WCC) and the New Zealand Historic Places Trust (NZHPT) worked together to oppose this unpopular decision. This protest was a seminal event in the history of heritage in New Zealand.  This study relies upon documentary sources, especially the archival records of the Historic Places Trust and the State Services Commission, who owned the building, to provide the history of this watershed moment in New Zealand’s preservation movement. The prevalent attitudes of different groups in Wellington are examined through the letters of protest they wrote at the time. When analysed in context, these discourses reveal the ways in which heritage was articulated and constructed.  The course of this dissertation has revealed the difficulty of identifying an AHD in this context. The level of collaboration between ‘official’ and ‘unofficial’ heritage perspectives, and the extent to which they shaped each other’s language, creates considerable difficulty in distinguishing between discreet discourses. To better explore the ways that heritage meaning is constructed and articulated, heritage must be recognised as a complex dynamic process.</p>

Hanshin Earthquake

Approximately one year after the Great Hanshin (Kobe) Earthquake, two New Zealand geologists were invited to help with the Geological Survey of Japan's paleoearthquake/active fault studies in the Kobe/Awaji area. Trenches excavated across the Nojima fault, which ruptured during the Great Hanshin Earthquake, showed evidence of past surface rupture earthquakes, with the age of the penultimate earthquake estimated at approximately 2000 years. A trench across the Higashiura fault, located 3-4 km southeast of the Nojima fault, revealed at least two past surface rupture earthquakes. The timing of the older earthquakes is not yet known, but pottery fragments found in the trench constrain the timing of the most recent earthquake at less than 500-600 years. Historical records for this part of Japan suggest that within the last 700 years there has been only one regionally felt earthquake prior to the 1995 Great Hanshin Earthquake, and this was the AD 1596 Keicho Earthquake. It thus seems reasonable to suggest that the Higashiura fault was, at least in part, the source of the AD 1596 Keicho Earthquake.
