Urban identities: influences on socio-environmental values and spatial inter-relations

This research focuses upon the socio-environmental dimensions and urban identity of urban environments by evaluating human behaviours and space-to-human relations. In addition, approaches to urban re-branding will be analysed to evaluate the role of engineered identities in enhancing social integration. This particular study will focus upon the installation of temporary activities into the public realm and the impact that these can have upon perception, identity and activity within public spaces. A case study of temporary markets taking place in Nottingham’s Old Market Square in the UK will be evaluated to explore possibilities of maximising the potential of urban space

The mechanism of Fe induced bond stability of uranyl( v )

The stabilization of uranyl(V) (UO21+) by Fe(II) in natural systems remains an open question in uranium chemistry. Stabilization of UVO21+ by Fe(II) against disproportionation was also demonstrated in molecular complexes. However, the relation between the Fe(II) induced stability and the change of the bonding properties have not been elucidated up to date. We demonstrate that U(V) – oaxial bond covalency decreases upon binding to Fe(II) inducing redirection of electron density from the U(V) – oaxial bond towards the U(V) – equatorial bonds thereby increasing bond covalency. Our results indicate that such increased covalent interaction of U(V) with the equatorial ligands resulting from iron binding lead to higher stability of uranyl(V). For the first time a combination of U M4,5 high energy resolution X-ray absorption near edge structure (HR-XANES) and valence band resonant inelastic X-ray scattering (VB-RIXS) and ab initio multireference CASSCF and DFT based computations were applied to establish the electronic structure of iron-bound uranyl(V)

Power variability of tidal-stream energy and implications for electricity supply

Temporal variability in renewable energy presents a major challenge for electrical grid systems. Tides are considered predictable due to their regular periodicity; however, the persistence and quality of tidal-stream generated electricity is unknown. This paper is the first study that attempts to address this knowledge gap through direct measurements of rotor-shaft power and shore-side voltage from a 1 MW, rated at grid-connection, tidal turbine (Orkney Islands, UK). Tidal asymmetry in turbulence parameters, flow speed and power variability were observed. Variability in the power at 0.5 Hz, associated with the 10-min running mean, was low (standard deviation 10–12% of rated power), with lower variability associated with higher flow speed and reduced turbulence intensity. Variability of shore-side measured voltage was well within acceptable levels (∼0.3% at 0.5 Hz). Variability in turbine power had <1% difference in energy yield calculation, even with a skewed power variability distribution. Finally, using a “t-location” distribution of observed fine-scale power variability, in combination with an idealised power curve, a synthetic power variability model reliably downscaled 30 min tidal velocity simulations to power at 0.5 Hz (R2 = 85% and ∼14% error). Therefore, the predictability and quality of tidal-stream energy may be undervalued in a future, high-penetration renewable energy, electricity grid

ISBS 2018 AUCKLAND CONFERENCE KIWIANA & INDUSTRY PARTNER PLAYING FIELD OPENING RECEPTION - ORDER OF PROCEEDINGS

The aim of the Kiwiana and Industry Partner Playing Field Opening Reception is to enable conference delegates to meet colleagues, make new acquaintances, learn about New Zealand (NZ) culture, experience quality NZ cuisine, and interact with new digital technology. The informative speeches (e.g. wine and food matching, cloudy bay clam research, Kiwiana research), thematic food stations (i.e. beach bach, farm, modern Kiwiana), interactive “ice-breaking” activities and competitions (e.g. jig saw building, gum boot throwing, number 8 wire sculpture, fishing), and social media photo opportunities (e.g. Kiwiana photo booth with VUTA) have been designed to help delegates achieve these goals. Native bird songs play while delegates walk into the fern and flax adorned atrium after the official opening. Delegates will receive a bubbly, beer, juice or mineral water on entry. Mr Kelly Sheerin, as the coordinator of the ISBS 2018 Conference industry partnership engagement programme, will outline the evening’s fun activities in the “Industry Playing Field” interactive events, and opportunities to win prizes. Dr Sarah-Kate Millar will provide the Karakia—blessing of the food. AUT Group Chef Matthew Farley, AUT Hospitality Services will explain the food and the Sileni wine for the evening. There are three savoury and two sweet canapés from cookbooks written by lecturers at AUT’s School of Hospitality and Tourism. Food is available from the Beach Bach, Farm, and Kiwiana themed areas. Lindsay Neill, kiwiana and Kiwi identity researcher, School of Hospitality, Tourism and Events, will outline the importance of kiwiana to New Zealand. His showcase will include the famous Buzzy Bee and findings from his latest research on kiwiana. Lindsay will highlight the uses of beetroot, tomato sauce, chocolate fish, Tip Top ice cream, and hokey pokey – regular food items for many NZers! We are really excited to showcase a special modern kiwiana food station with finger food adapted from books by AUT School of Hospitality, Tourism and Events staff. Students from the School’s culinary programmes are assisting to prepare and serve the food for your enjoyment including: Cured salmon, rice cracker, pickled ginger, spring onion; Corn fritters; Suqaar Digaag Somali chicken; White chocolate tart with chocolate cremeux and Swiss merengue; Misiluki banana pudding with Siamu Popo. Professor Lindsay White, Cloudy Bay Clams researcher, School of Applied Sciences, will outline the research behind producing Cloudy Bay Clams. His showcase will provide tastings of fresh seafood. Surf clams is the collective term for seven commercially harvested molluscs that live on almost all of NZ sandy, high wave energy beaches. They live buried in the sand, just in or behind the breaking waves. Regional small-scale studies indicate that surf clams have the potential to be NZ’s most valuable fishery resource, but a lack of scientific knowledge about these species allows only a tiny fraction of the sustainable harvest to be currently harvested. Our research to date has had a huge impact on the national fishery, more than doubling the total catch of surf clams, which equates to increases in annual export earnings of over $27 million. Based on this work, in 2013 we jointly won the Kiwi Supreme Prize for Commercialisation of Research. Tim Davison’s team will introduce the interactive virtual AUTer (VUTA). VUTA is the virtual MC for the Opening Kiwiana event alongside Kelly Sheerin as the in-the-flesh MC! Tim will explain how delegates can interact with VUTA by scanning the code in messenger. VUTA can make announcements, answer questions, display messages, greet people, and move around. Tim has been able to customise her to do just about anything. Samsung flip screens (https://displaysolutions.samsung.com/digital-signage/e-board/flip) are used for directional information and Tim’s VUTA. Thanks to Industry partner Samsung for providing the hardware to enable VUTA to come to life. Professor Len Gillman, School of Applied Sciences - Conference Sustainability—ecological responsibility, will explain the food and waste compositing, no single use plastics, and vegan options for the conference. Len and Professor Thomas Neitzert (School of Engineering) have calculated the carbon footprint for international delegates flying to NZ for the conference is 186.5 tonnes of carbon! Therefore 1.86 hectares (4.6 acres) will need to be planted to offset the conference travel. Strategies undertaken by the ISBS 2018 conference organising committee to help offset the carbon cost include the planting of native trees, promotion of recycling of bottles and compositing of food during the conference, vegan meal options, use of low energy LED lights and solar lights, minimised use of plastic products with no single-use plastic, digital posters rather than printing posters, and puffer jackets as the ‘conference bag’ as a useful reusable item. Lindsey du Preez is the AUT Sustainability Officer. Lindsey has worked with the AUT Hospitality Services team to provide initiatives that have a strong focus on sustainability for the conference. Some of the key initiatives are: This is a paperless conference and all material is digital including conference proceedings and posters; AUT is working towards eliminating ‘single use plastic’, so this is avoided wherever possible. Water will be provided in jugs with glass containers, and unpacked teabags and chocolates have been sourced directly from suppliers to reduce unnecessary packaging; Reusable cutlery and crockery will be provided to avoid unnecessary waste; Serviettes are compostable; 25% of the food provided is vegetarian and food is sourced locally wherever possible; three bin-system will be provided for rubbish, mixed recycling (plastic bottles types 1 & 2, essentially milk bottles and drink bottles, glass, cans) and organic waste; All leftover food will be composted, and every effort made to avoid over catering; Support of Fair Trade and all coffee is Fair Trade; The conference is next to a major bus terminus for easy access to public transport. The Kiwiana interactive showcase photo competition will be run by Kylie Robinson. Post the best photo of you and fellow delegates in the Kiwiana interactive showcase photo booth that includes jandals, flora (flax, punga ferns), fauna (Tui, Kiwi, geko, pukeko, kea), paua, a rugby ball, NZ sliver fern, flags, sheep, swandri, gumboots, #8 wire, L&P bottle, chocolate fish, tomato sauce bottle, buzzy bee, kiwi fruit. Thanks to AMTI for the chocolate fish. We have taken a different approach to our “sponsors” for the conference, preferring to have engaged industry partners. Industry Partners are treated like any other conference delegates in terms of registration, with an expectation that there is active engagement and preparation of a workshop, applied session or industry partner playing field event – just like a delegate would prepare an oral podium or a poster pitch and digital poster. Our industry partners have adapted to this new format with enthusiasm. We hope that delegates take up the opportunity to interact with the Industry Partner delegates, particularly in the playing field sessions where there are participatory games. Aerobe will be demonstrating their simple to use active marker technology Codamotion system to track the knee and ankle joints during a series of jump activities. Thanks to the industry partners who have participated in the industry partner programme. Platinum industry partner VICON are providing the ISBS 2018 conference puffer jackets to those who registered by the standard registration date. Vicon are also providing beverages for conference events. Diamond industry partner SILENI are providing amazing wines for all the conference events. We have a large selection from the Sileni range including Marlborough Sauvignon blanc, pinot gris, pinot noir, sparkling cuvee brut, merlot etc. Diamond industry partner SAMSUNG are providing new FLIP technology screens, 55” screens for the digital poster sessions, and the Note9 and DeX station for social media interaction and prizes. Gold industry partner ACC is supporting the Keynote panel speakers and a round table luncheon. Gold industry partner KISTLER are supporting two round table luncheons, and Olympic athletes at the AUT Millennium event. Gold industry partners QUALISYS and NORAXON are providing workshops and AUT Millennium applied sessions. Gold industry partner AMTI are supporting the chocolate box stations and the student evening at the marae. Silver industry partner FORCEDECKS are supporting the Commercialisation and Funding Monday workshop. Bronze industry partner CHANUI are providing tea and biscuits for breaks. Bronze industry partner AEROBE are supporting the Wise Wizards keynote panel. Bronze industry partner TEKSCAN are supporting the Sports Technology long table luncheon. Bronze industry partner STT Systems are supporting the fruit baskets. Bronze industry partner ASICS are providing shoes for social media prizes and a chill-out zone. Bronze industry partner SIMI are showcasing their technology at an industry booth

The Recent Star Formation in NGC 6822: an Ultraviolet Study

We characterize the star formation in the low-metallicity galaxy NGC 6822 over the past few hundred million years, using GALEX far-UV (FUV, 1344-1786 A) and near-UV (NUV, 1771-2831 A) imaging, and ground-based Ha imaging. From GALEX FUV image, we define 77 star-forming (SF) regions with area >860 pc^2, and surface brightness <=26.8 mag(AB)arcsec^-2, within 0.2deg (1.7kpc) of the center of the galaxy. We estimate the extinction by interstellar dust in each SF region from resolved photometry of the hot stars it contains: E(B-V) ranges from the minimum foreground value of 0.22mag up to 0.66+-0.21mag. The integrated FUV and NUV photometry, compared with stellar population models, yields ages of the SF complexes up to a few hundred Myr, and masses from 2x10^2 Msun to 1.5x10^6 Msun. The derived ages and masses strongly depend on the assumed type of interstellar selective extinction, which we find to vary across the galaxy. The total mass of the FUV-defined SF regions translates into an average star formation rate (SFR) of 1.4x10^-2 Msun/yr over the past 100 Myr, and SFR=1.0x10^-2 Msun/yr in the most recent 10 Myr. The latter is in agreement with the value that we derive from the Ha luminosity, SFR=0.008 Msun/yr. The SFR in the most recent epoch becomes higher if we add the SFR=0.02 Msun/yr inferred from far-IR measurements, which trace star formation still embedded in dust (age <= a few Myr).Comment: Accepted for publication in ApJ, 21 pages, 6 figures, 3 table

Habitat structure shapes temperate reef assemblages across regional environmental gradients

Intertidal artificial habitats are proliferating, but are generally simpler in structure and host lower biodiversity than natural rocky reefs. Eco-engineering aims to enhance the biodiversity of coastal infrastructure, often through physical structural modifications that mimic topographic properties of natural shores. Relationships between biotic assemblages and structural properties of natural and artificial reefs have been extensively studied at sampling scales of up to 1 m2. But evidence that quantified local structural variation has an appreciable influence on biotic assemblages, at a shore-wide scale across regional environmental gradients, is lacking. Here we addressed this knowledge gap with an observational study at 32 natural and artificial intertidal reef sites in Wales, UK. We used multivariate community analysis and permutation tests to examine associations between local physical structure, regional environmental variables and sessile biotic assemblages. A potential influence of local habitat structure on assemblage composition was evident across regional-scale environmental gradients. Compared to natural sites, artificial reefs had lower taxonomic richness, distinct and more variable assemblage composition, and different physical structure. After removing the effect of habitat (natural or artificial), canonical correspondence analysis showed that environmental variables (wave exposure, sea surface temperature and salinity variation), along with two metrics of physical structure (standard deviation in log-transformed detrended roughness and skewness of surface verticality, both at 0.5 m scale), explained 40 % of the variation in assemblage composition among sites. The two structural metrics independently explained 14.5 % of the variation. Associations identified between individual taxa and environmental variables indicated that sites with a higher proportion of horizontal surfaces hosted more canopy macroalgae, which in turn support other algae and invertebrates. Our findings provide evidence to inform scaling-up of structural eco-engineering interventions from experimental contexts to enhance the biodiversity of coastal infrastructure across regional extents

Methods to estimate aboveground wood productivity from long-term forest inventory plots

Forest inventory plots are widely used to estimate biomass carbon storage and its change over time. While there has been much debate and exploration of the analytical methods for calculating biomass, the methods used to determine rates of wood production have not been evaluated to the same degree. This affects assessment of ecosystem fluxes and may have wider implications if inventory data are used to parameterise biospheric models, or scaled to large areas in assessments of carbon sequestration. Here we use a dataset of 35 long-term Amazonian forest inventory plots to test different methods of calculating wood production rates. These address potential biases associated with three issues that routinely impact the interpretation of tree measurement data: (1) changes in the point of measurement (POM) of stem diameter as trees grow over time; (2) unequal length of time between censuses; and (3) the treatment of trees that pass the minimum diameter threshold (“recruits”). We derive corrections that control for changing POM height, that account for the unobserved growth of trees that die within census intervals, and that explore different assumptions regarding the growth of recruits during the previous census interval. For our dataset we find that annual aboveground coarse wood production (AGWP; in Mg ha−1 year−1 of dry matter) is underestimated on average by 9.2% if corrections are not made to control for changes in POM height. Failure to control for the length of sampling intervals results in a mean underestimation of 2.7% in annual AGWP in our plots for a mean interval length of 3.6 years. Different methods for treating recruits result in mean differences of up to 8.1% in AGWP. In general, the greater the length of time a plot is sampled for and the greater the time elapsed between censuses, the greater the tendency to underestimate wood production. We recommend that POM changes, census interval length, and the contribution of recruits should all be accounted for when estimating productivity rates, and suggest methods for doing this.European UnionUK Natural Environment Research CouncilGordon and Betty Moore FoundationCASE sponsorship from UNEP-WCMCRoyal Society University Research FellowshipERC Advanced Grant “Tropical Forests in the Changing Earth System”Royal Society Wolfson Research Merit Awar

A collaboratively produced model of service design for children and young people with common mental health problems

Background: Little is known about the effectiveness of, and implementation complexities associated with, service delivery models for children and young people (CYP) experiencing ‘common’ mental health problems such as anxiety, depression, behavioural difficulties and self-harm. This paper outlines how a model for high-quality service design for this population group was developed by identifying available services, their effectiveness, cost-effectiveness and acceptability, and the barriers and enablers to access. Methods: Sequential, mixed-methods design, combining evidence syntheses (scoping and integrative reviews of the international literature) with primary research (a collective case study in England and Wales). Data from these two elements were collaboratively synthesised in a subsequent model-building phase. Results: The scoping review yielded a service model typology. The integrative review found effectiveness evidence only for four models: collaborative care (the only service model to also have cost-effectiveness evidence), outreach approaches, brief intervention services and an organisational framework called ‘Availability, Responsiveness and Continuity’. No service model seemed more acceptable than others. Three case study themes were identified: pathways to support; service engagement; and learning and understanding. The model-building phase identified rapid access, learning self-care skills, individualised support, clear information, compassionate and competent staff and aftercare planning as core characteristics of high-quality services. These characteristics were underpinned by four organisational qualities: values that respect confidentiality; engagement and involvement; collaborative relationships; and a learning culture. Conclusions: A consistent organisational evidence-base for service design and delivery in CYP’s mental health spanning many years appears to have had little impact on service provision in England and Wales. Rather than impose – often inflexible and untested – specific local or national models or frameworks, those commissioning, designing and delivering mental health services for CYP should (re)focus on already known, fundamental components necessary for high-quality services. These fundamental components have been integrated into a collaboratively produced general model of service design for CYP with common mental health problems. While this general model is primarily focused on British service provision, it is broad enough to have utility for international audiences

LSST: from Science Drivers to Reference Design and Anticipated Data Products

(Abridged) We describe here the most ambitious survey currently planned in the optical, the Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST will have unique survey capability in the faint time domain. The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the Solar System, exploring the transient optical sky, and mapping the Milky Way. LSST will be a wide-field ground-based system sited at Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m effective) primary mirror, a 9.6 deg$^2$ field of view, and a 3.2 Gigapixel camera. The standard observing sequence will consist of pairs of 15-second exposures in a given field, with two such visits in each pointing in a given night. With these repeats, the LSST system is capable of imaging about 10,000 square degrees of sky in a single filter in three nights. The typical 5$\sigma$ point-source depth in a single visit in $r$ will be $\sim 24.5$ (AB). The project is in the construction phase and will begin regular survey operations by 2022. The survey area will be contained within 30,000 deg$^2$ with $\delta<+34.5^\circ$, and will be imaged multiple times in six bands, $ugrizy$, covering the wavelength range 320--1050 nm. About 90\% of the observing time will be devoted to a deep-wide-fast survey mode which will uniformly observe a 18,000 deg$^2$ region about 800 times (summed over all six bands) during the anticipated 10 years of operations, and yield a coadded map to $r\sim27.5$. The remaining 10\% of the observing time will be allocated to projects such as a Very Deep and Fast time domain survey. The goal is to make LSST data products, including a relational database of about 32 trillion observations of 40 billion objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures available from https://www.lsst.org/overvie

LSST Science Book, Version 2.0

A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade. The Large Synoptic Survey Telescope (LSST) will have an effective aperture of 6.7 meters and an imaging camera with field of view of 9.6 deg^2, and will be devoted to a ten-year imaging survey over 20,000 deg^2 south of +15 deg. Each pointing will be imaged 2000 times with fifteen second exposures in six broad bands from 0.35 to 1.1 microns, to a total point-source depth of r~27.5. The LSST Science Book describes the basic parameters of the LSST hardware, software, and observing plans. The book discusses educational and outreach opportunities, then goes on to describe a broad range of science that LSST will revolutionize: mapping the inner and outer Solar System, stellar populations in the Milky Way and nearby galaxies, the structure of the Milky Way disk and halo and other objects in the Local Volume, transient and variable objects both at low and high redshift, and the properties of normal and active galaxies at low and high redshift. It then turns to far-field cosmological topics, exploring properties of supernovae to z~1, strong and weak lensing, the large-scale distribution of galaxies and baryon oscillations, and how these different probes may be combined to constrain cosmological models and the physics of dark energy.Comment: 596 pages.
