Land use in rural New Zealand: spatial land use, land-use change, and model validation

Abstract Land is an important social and economic resource. Knowing the spatial distribution of land use and the expected location of future land-use change is important to inform decision makers. This paper documents and validates the baseline land-use maps and the algorithm for spatial land-use change incorporated in the Land Use in Rural New Zealand model (LURNZ). At the time of writing, LURNZ is the only national-level land-use model of New Zealand. While developed for New Zealand, the model provides an intuitive algorithm that would be straightforward to apply to different locations and at different spatial resolutions. LURNZ is based on a heuristic model of dynamic land-use optimisation with conversion costs. It allocates land-use changes to each pixel using a combination of pixel probabilities in a deterministic algorithm and calibration to national-level changes. We simulate out of sample and compare to observed data. As a result of the model construction, we underestimate the “churn” in land use. We demonstrate that the algorithm assigns changes in land use to pixels that are similar in quality to the pixels where land-use changes are observed to occur. We also show that there is a strong positive relationship between observed territorial-authority-level dairy changes and simulated changes in dairy area

Hybrid Wall Outlet for AC or DC Power Delivery

The goal of this project is to develop hybrid DC and AC wall outlets for an efficient, flexible power interface. A DC plug standard is also proposed to allow DC devices to be safely powered by the outlet with the correct DC voltage for each device. The primary objective is to create a power outlet compatible with the proposed DC plug as well as NEMA 5-15 AC plugs, enabling the same outlet to power both types of load as needed. The outlet is intended for buildings and systems transitioning to an isolated DC grid to encourage DC development and adoption. Existing wall wiring will be given 48V DC and used to power these devices, avoiding expensive rewiring when retrofitting. The outlet uses an H-bridge topology to facilitate DC to AC conversion, a Boost topology to reach standard wall voltage, and a Buck topology for DC voltage applications

Towards energetically viable asymmetric deprotonations : selectivity at more elevated temperatures with C2-symmetric magnesium bisamides

A novel chiral magnesium bisamide has enabled the development of effective asymmetric deprotonation protocols at substantially more elevated temperatures. This new, structurally simple, C2-symmetric magnesium complex displays excellent levels of asymmetric efficiency and energy reduction in the synthesis of enantioenriched enol silane

Finalising an item bank for a first draft cardiac rehabilitation PROM

Background: A Scotland-wide scoping exercise identified the need for a new patient-reported outcome measure (PROM) to suit the range of diagnostic groups now accessing cardiac rehabilitation (CR). A previous literature review of existing tools guided a qualitative methodology involving CR staff and service users (Cowie et al, 2018). Aim: This paper describes the merging of literature review findings with qualitative data to finalise the item bank for a first draft tool (PROM-CR1). Methods: Conceptual ideas identified from existing tools were aligned with key themes and subthemes within the qualitative data. Quotes most reflective of the qualitative language were used to evidence themes and develop 40 construct indicators which were used to build PROM-CR1. Results: PROM-CR1 contains 40 items across 'physical', 'social', 'psychological' and 'therapeutic' domains, plus 'general health and well-being', 'physical', 'social', and 'psychological' summary scores. Future directions: PROM-CR1 will be piloted with both staff and service users, and refined to develop a finalised tool (PROM-CR) for clinical practice

Developing an initial item bank for a new cardiac rehabilitation PROM

Background: A Scotland-wide government scoping exercise identified the need for a new patient-reported outcome measure (PROM) suitable for the wide range of diagnostic groups now accessing cardiac rehabilitation (CR). Aim: This paper describes the initial steps underpinning development of the item bank for a first draft tool (PROM–CR1). Methods: A literature review of existing tools was undertaken to guide a qualitative data collection methodology involving 19 CR staff and 22 service users. Results: Four conceptual ideas for health/quality of life were identified from the literature review: general health; physical; social; and psychological. Three key qualitative themes, largely reflective of literature review findings, were identified: expectations and entitlement; adjustment and acceptance; and control and choice. Future directions: These data will be combined to form PROM-CR1’s initial item bank, which will be piloted with staff and service users and refined to generate a finalised tool (PROM–CR) for use in clinical practice

Neuromechanical differences between successful and failed sit-to-stand movements and response to rehabilitation early after stroke

Background. Recovery of the sit-to-stand (StS) movement early after stroke could be improved by targeting physical therapy at the underlying movement deficits in those people likely to respond. Aim. To compare the movement characteristics of successful and failed StS movements in people early after stroke and identify which characteristics change in people recovering their ability to perform this movement independently following rehabilitation. Methods. Muscle activity and kinematic (including center of mass, CoM) data were recorded from 91 participants (mean 35 days after stroke) performing the StS movement before (baseline), immediately after (outcome), and 3 months after (follow-up) rehabilitation. Three subgroups (never-able [n = 19], always-able [n = 51], and able-after-baseline [n = 21]) were compared at baseline with the able-after-baseline subgroup compared before and after rehabilitation. Results. The subgroups differed at baseline for quadriceps onset time (P = .009) and forward body position when quadriceps peaked (P = .038). Following rehabilitation, the able-after-baseline subgroup increased their forward position (P < .001), decreased the time difference between bilateral quadriceps peaks (P < .001) and between quadriceps and hamstrings peaks on the nonhemiplegic side (P = .007). An improved performance in the always-able subgroup was associated with a number of baseline factors, including forward positioning (P = .002) and time difference between peak activity of bilateral quadriceps (P = .001). Conclusions. This neuromechanical study of StS before and after rehabilitation in a sample of people early after stroke identified the importance of temporal coupling between forward trunk movement and quadriceps and hamstrings’ activity. These findings advance the science of stroke rehabilitation by providing evidence-based therapy targets to promote recovery of the StS movement
