Dissecting the Discourse of Social Licence to Operate
(1/08/2018) Sinner J; Newton M; Farrelly T
The term “social licence to operate”, or SLO, has increasingly featured in public discussion about commercial operations in the marine environment. As part of the Sustainable Seas National Challenge, we are studying how this term is being used in New Zealand and its implications for industry-community relations.
Why so unfit?: Assessing potential barriers to exercise adoption in middle-aged men
(The Author(s), 10/02/2005) Towers AJ; Flett RA; Seebeck RF; Towers, AJ; Flett, RA; Seebeck, RF
Compared to women, men:  have a higher mortality rate  consistently die younger  are more susceptible to sedentary-lifestyle related diseases (e.g., cardiovascular disease)  are more likely to engage in behaviours that increase risk of injury, disease, or death  are less likely to seek help with physical health. Despite these statistics, the amount of literature devoted to women’s health in the past two decades still greatly exceeds that devoted to men’s health. The result is that we actually know very little about what influences men’s health behaviours. Introduction We utilised the transtheoretical model of exercise behaviour change to determine the pattern of exercise adoption in middle-aged men. We also analysed whether this pattern was influenced by three potential barriers to exercise: poor self-rated health, low levels of internal health locus of control, and high perceived stress levels. Hypotheses Compared to participants in the last stage of change (maintenance), it was hypothesised that participants in the first stage of exercise change (precontemplation) would have:  lower self-efficacy  less concern over the pros of exercise  more concern over the cons of exercise  poorer self-rated health  higher levels of perceived stress  lower levels of internal health locus of control [From Introduction]

Short-term effects of deep ploughing on soil C stocks following renewal of a dairy pasture in New Zealand
(14/08/2018) Calvelo Pereira R; Hedley MJ; Hanly J; Bretherton M; Horne D; Bishop P; Beare M; McNally S
In New Zealand’s high producing permanent pastures the topsoil constitutes a large reservoir of soil organic carbon (SOC), which shows a marked stratification with depth. As consequence, sub-surface layers can contain 10 times less carbon than the surface soil. In permanent pastures with high carbon inputs, the formation and decomposition of these surface SOC stocks are often at equilibrium and C storage shows little change over time. Pastoral based dairy systems utilising ryegrass plus clover cultivars require renewal every 7-10 years to avoid reversion to less productive grasses. This may involve spring cultivation (either no-till, shallow till or full cultivation), summer forage cropping and autumn re-grassing. It has been hypothesised that SOC stocks can be increased by inverting the soil profile at pasture renewal through infrequent (once in 25-30 years) deep mouldboard ploughing (up to 30 cm depth). Increased C sequestration occurs when the new grass quickly rebuilds SOC stocks in the new topsoil (exposed low C sub-soil) at a rate faster than the decomposition of SOC in the rich former topsoil transferred to depth (now below 15 cm). However, benefits form accelerated C storage may be offset if crop and pasture production is adversely affected by the ploughing event (e.g., as result of compaction or excessive drainage). Hence, the aim of this work was to assess the short-term effects of infrequent inversion tillage of long-term New Zealand pastoral-based dairy soils under summer crop management and autumn re-grassing. An imperfectly drained Typic Fragiaqualf under dairy grazing was deep ploughed (approx. 25 cm) and re-sown with turnip in October 2016; other treatments included were shallow (< 10 cm) cultivation and no-till. The site was core sampled (0-40 cm) before cultivation and after 5 months of turnip growth to assess changes in SOC. Plant growth, herbage quality, and nutrient leaching were monitored during the 5-month period; root growth was assessed at the end of the crop rotation. Full cultivation transferred SOC below 10 cm depth, as expected. Soil bulk density decreased whereas root mass increased (10-20 cm depth; P < 0.05) under deep cultivation only. Besides, losses of mineral N were attenuated under deep tillage, resulting in a relative increase in crop yield. The potential for infrequent inversion tillage increasing soil C sequestration as a greenhouse gas (GHG) mitigation tool is currently being tested at other sites in New Zealand.

"Where did I park my car?" How do older adults cope with a diagnosis of mild cognitive impairment
(16/11/2011) McKinlay AR; Leathem JM; Merrick PL
Background: This presentation will background a New Zealand based research study to be conducted this year focusing on how people cope with and adjust to a diagnosis of mild cognitive impairment (MCI). This area of research is important because as a person reaches older age, their chances of developing a certain set of age related illnesses, such as dementia and cognitive impairment increases (Larson, 2010; Coulson et al., 2005; Hughes & Heycox, 2010). At the same time, the number of adults aged 65 and over is set to increase at levels unseen in Western Society to date in coming years. By 2050, the world's population of older adults is estimated to reach over 22% in its entirety, which roughly equates to a staggering 1 and a quarter billion people (Lloyd-Sherlock, 2010). Adjusting to and coping with a diagnosis of cognitive impairment can be difficult and is comparable to receiving a diagnosis of other chronic diseases (Preston, Marshall & Bucks, 2007). Some report depression, anxiety and other psychological reactions following their dementia diagnosis (Carpenter et al., 2008). Current literature to date is divided on how people react psychologically to knowing that they have a progressive cognitive impairment, and much of the research has overlooked the issue of MCI and the associated reactions to this diagnosis.
Sensitivity to Volcanic Field Boundary
(17/04/2016) Whitehead M; Bebbington M; Cronin S; Moufti MR; Lindsay J
Volcanic hazard analyses are desirable where there is potential for future volcanic activity to affect a proximal population. This is frequently the case for volcanic fields (regions of distributed volcanism) where low eruption rates, fertile soil, and attractive landscapes draw populations to live close by. Forecasting future activity in volcanic fields almost invariably uses spatial or spatio-temporal point processes with model selection and development based on exploratory analyses of previous eruption data. For identifiability reasons, spatio-temporal processes, and practically also spatial processes, the definition of a spatial region is required to which volcanism is confined. However, due to the complex and predominantly unknown sub-surface processes driving volcanic eruptions, definition of a region based solely on geological information is currently impossible. Thus, the current approach is to fit a shape to the known previous eruption sites. The class of boundary shape is an unavoidable subjective decision taken by the forecaster that is often overlooked during subsequent analysis of results. This study shows the substantial effect that this choice may have on even the simplest exploratory methods for hazard forecasting, illustrated using four commonly used exploratory statistical methods and two very different regions: the Auckland Volcanic Field, New Zealand, and Harrat Rahat, Kingdom of Saudi Arabia. For Harrat Rahat, sensitivity of results to boundary definition is substantial. For the Auckland Volcanic Field, the range of options resulted in similar shapes, nevertheless, some of the statistical tests still showed substantial variation in results. This work highlights the fact that when carrying out any hazard analysis on volcanic fields, it is vital to specify how the volcanic field boundary has been defined, assess the sensitivity of boundary choice, and to carry these assumptions and related uncertainties through to estimates of future activity and hazard analyses.

The changing nature of life regrets
(18/11/2008) Towers AJ; Flett RA; Hill SR; Alpass FM
IntroductionNew life stages promote new life goals and our most intense regrets should change in relation to our new goals and priorities.Research shows that 'Work' and 'Education' regrets are more common for older adults, who also tend to regret their inactions more than their actions. However, past research focuses in frequency and fails to indicate which regrets are actually more intense.We still don't know whether regret intensity changes with time and whether our most frequent regrets are also our most intense. Furthermore, we don't know whether regret-reducing processes, such as justification, are employed differentially across the life-span.

Engaging in spaces: How mature distance students fit study into their homes and lives
(2/07/2013) Kahu ER
In order to fit study around family and work, a third of mature aged tertiary students in New Zealand study by distance. By enabling students to study when and where they want, distance study is said to overcome the barriers of space and time. But space and time must still be found and the blurring of the physical boundaries between study and home creates new challenges. While much has been written about how distance students juggle time, little has considered how they manage space; yet it is often the availability of an appropriate learning space that determines not just when and where they study, but the quality of their engagement. This qualitative study, following 19 mature aged distance students and their families through their first semester, examines how the students carved learning spaces from their busy lives, the nature of those spaces, and the impact this had on their engagement. For some, a space without other people was the essential characteristic and they achieved this through either a physical separation strategy such as studying at work, or a temporal separation strategy such as studying only when children were at school. For others, isolation was a barrier to their engagement and they gravitated to shared living spaces. Individual lifeload, context, and personal preference mean there are no right or wrong choices, but family support is a critical influence on the success of different strategies.
Structural determination of archaeal UDP-N-acetylglucosamine 4-epimerase from Methanobrevibacter ruminantium M1 in complex with the bacterial cell wall intermediate UDP-N-acetylmuramic acid
(2/12/2018) Carbone V; Schofield L; Sang C; Sutherland-Smith A; Ronimus RS
The crystal structure of UDP-N-acetylglucosamine 4-epimerase (UDP-GlcNAc 4-epimerase; WbpP; EC 5.1.3.7), from the archaeal methanogen Methanobrevibacter ruminantium strain M1, was determined to a resolution of 1.65 Å. The structure, with a single monomer in the crystallographic asymmetric unit, contained a conserved N-terminal Rossmann fold for nucleotide binding and an active site positioned in the C-terminus. UDP-GlcNAc 4-epimerase is a member of the short-chain dehydrogenase/reductase superfamily, sharing sequence motifs and structural elements characteristic of this family of oxidoreductases and bacterial 4-epimerases. The protein was co-crystallized with coenzyme NADH and UDP-N-acetylmuramic acid, the latter an unintended inclusion and well known product of the bacterial enzyme MurB and a critical intermediate for bacterial cell wall synthesis. This is a non-native UDP sugar amongst archaea and was most likely incorporated from the Eschericha coli expression host during purification of the recombinant enzyme.
sFlt-1 and NTproBNP independently predict mortality in a cohort of heart failure patients.
(2/12/2018) Paterson MA; Pilbrow AP; Frampton CM; Cameron VA; Pemberton CJ; Lund M; Devlin GP; Doughty RN; Richards AM; Palmer B
Objective: Soluble fms-like tyrosine kinase-1 (sFlt-1) is a circulating receptor for VEGF-A. Recent reports of elevated plasma levels of sFlt-1 in coronary heart disease and heart failure (HF) motivated our study aimed at investigating the utility of sFlt-1 as a prognostic biomarker in heart failure patients. Methods: ELISA assays for sFlt-1 and NTproBNP were performed in n=858 patients from a prospective multicentre, observational study (the PEOPLE study) of outcome among patients after appropriate treatment for an episode of acute decompensated HF in New Zealand. Plasma was sampled at a baseline visit and stored at -80°C. Statistical tests were adjusted for patient age at baseline visit, skewed data were log-adjusted and the endpoint for clinical outcome analysis was all-cause death. Patients were followed for a median of 3.63 (range 0.74-5.50) years. Results: Mean baseline plasma sFlt-1 was 125 +/- 2.01 pg/ml. sFlt-1 was higher in patients with HF with reduced ejection fraction (HFrEF) (130 +/- 2.62 pg/ml, n=553) compared to those with HF with preserved EF (HFpEF) (117 +/-3.59 pg/ml, n=305; p=0.005). sFlt-1 correlated with heart rate (r=0.148, p<0.001), systolic blood pressure (r=-0.139, p<0.001) and LVEF (r=-0.088, p=0.019). A Cox proportional hazards model showed sFlt-1 was a predictor of all-cause death (HR=6.30, p<0.001) in the PEOPLE cohort independent of age, NTproBNP, ischaemic aetiology, and NYHA class (n=842, 274 deaths), established predictors of mortality in the PEOPLE cohort. Conclusion: sFlt-1 levels at baseline should be investigated further as a predictor of death; complementary to established prognostic biomarkers in heart failure.
