<p>England and New Zealand introduced pay-for-performance schemes in their primary health care systems, with incentives for general practitioners to achieve improved population-based health outcomes, between 2001 and 2007. These schemes were part of health reforms to change the relationship between the state and the medical profession, giving the state increased influence over the quality and allocation of publicly funded health care. Two schemes of differing size, scope and impact were implemented. This research takes a comparative approach to exploring each policymaking process, utilising quasi-natural experimental conditions in these two Westminster governing systems to test the relevance of Kingdon’s multi-theoretic Multiple Streams Framework and other theoretical approaches to explain policy variation and change.  The research documented and analysed the agenda-setting, alternative selection and implementation phases in the two policymaking processes and identified the key drivers of policymaking in each case study. A qualitative methodology, based upon documentary analysis and semi-structured interviews with 26 decision-makers, leaders and participants, was used to develop the two case studies, providing rich descriptive details and rare insights into closed policymaking approaches as seen by the participants. From this case study evidence, themes were drawn out and reviewed for consistency with Kingdon’s Multiple Streams Framework as it has been interpreted and adapted by Zahariadis. The case study evidence and themes were considered in a framework of comparative analysis where patterns of similarity and difference were established. The utility of Kingdon’s Multiple Streams Framework in interpreting the case study evidence was assessed.  This analysis demonstrated that Kingdon’s Framework, as interpreted by Zahariadis, had high descriptive power for both case studies but failed to predict the patterns of non-incremental change observed or the importance of institutional factors such as ownership and governance arrangements for public services, interest group structure and historical antecedents seen in the two policymaking processes.  The research finds that the use of bargaining in England and not in New Zealand is the reason for major differences in speed, scope and outcomes of the two pay-for-performance schemes. Institutional structures in the general practice sub-system are therefore the primary driver of policy change and variation. These acted as enablers of non-incremental change in the English case study, providing incentives for actors individually and collectively to design and rapidly to implement a large-scale pay-for-performance scheme. The institutional features of the general practice sub-system in New Zealand acted as a constraint to the development of a large-scale scheme although non-incremental change was achieved. Phased approaches to implementation in New Zealand were necessary and slowed the delivery of outcomes from the scheme.  With respect to other drivers of policy change and variation, the role of individual actors as policy and institutional entrepreneurs was important in facilitating policy design in each country, with different types of entrepreneurs with different skills being observed at different stages of the process. These entrepreneurs were appointed and working within the bureaucracy to the direction of decision-makers in both countries. England and New Zealand shared ideas about the benefits of New Public Management approaches to public policymaking, including support for pay-for-performance approaches, and there was a shared positive socio-economic climate for increased investment in health services.  The research provides evidence that Westminster governing systems are capable of purposeful and orderly non-incremental health policy change and that Kingdon’s Multiple Streams Framework, which theorises policy formation in conditions of ambiguity, needs to be enhanced to improve its relevance for such jurisdictions. Recommendations for its enhancement are made.</p>

Actions to reduce greenhouse gas emissions are required from all actors. Adopting plug-in electric vehicles (EV) would reduce light motor vehicle travel emissions, a significant and rising emissions source. To encourage EV uptake, many governments have implemented policies which may be less effective than desired. Using New Zealand as a case study, we surveyed private motorists. The results show that consumers are heterogeneous, with varying car-buying motivations, perceptions, attitudes to EVs and awareness of policies. Uniquely, we segmented motorists into four attitudinal groups to ascertain characteristics potentially affecting EV readiness to provide evidence to improve policies and aid social marketing. Our results show the next-most-ready to buy EVs are early mainstream consumers—designated the EV Positives—who were most concerned about vehicle range, perceptions of EV expense, charging-related inconvenience and the unknown value proposition of batteries, and were relatively unaware of incentives compared to EV Owners. The EV Positives favored incentives designed to effect purchase price reductions and increase nation-wide fast-charger deployment. To increase awareness of EVs and shift perceptions of EV expense and inconvenience, we suggest policies that potentially increase EV adoption rates and suggest reframing the language to appeal to EV Positives through information programs. Increasing EV procurement by organizations could increase opportunities for positive information dissemination via employees.

<p>This thesis explores how issues that have arisen from large scale ferry ports and industrial developments have resulted in disrupting the connectivity to neighbouring townships. It proposes a novel architecturally resolved terminal and ferry port, with a speculative siting in Picton to re-establish a relationship between port and township through connectivity and synergy.  Rapid change, growth and master planning within the ferry industry all play a vital role in anticipating land and infrastructural needs. A key interface between a roro (roll-on roll-off) vessel and the shore is essential to ensure optimum traffic flow for fast operation. Due the ferry’s roro service of transporting and carrying vehicles it is common for the main highways to and from the port to bypass a neighbouring township, resulting in fewer tourists visiting the neighbouring town centre. Railway tracks also play a similar role in creating boundaries of segregation between the port and town. In towns where the port is disproportionately large in relation to township, such as Dover in South-East England, Ballygillane, Rosslare Ireland and Picton New Zealand, infrastructural pressures have resulted in an imbalance in hierarchy between the ferry port and the township. It is important to re-establish a relationship between ferry ports and their neighbouring towns to rehabilitate the small township to ensure its place for future use.  The thesis investigates architecture’s role in reconciling a large scale ferry terminal with a small township. It asks how architecture, urban design and infrastructure can be applied to a township to enforce connectivity between ferry port and town. This thesis explores the question by proposing a case study design in Picton New Zealand. The relationship that roro ferry terminals have to their local context is impeded by train tracks, rail yards, car parking and marshalling yards. To analyse this large land-use component, the design uses three key functioning scales; Urban, Infrastructure and Architectural. i) Urban: The Urban Design reinforces the connection of the land to the sea. This was achieved by excavating a large portion of reclaimed land. This acknowledges the towns past and history, both topographically and culturally. This was developed into a new marina, bringing the sea edge closer to the township acting as a connection to the terminal and port.  (ii) Infrastructure: Functionality and layout is critical, Port infrastructure layouts were studied to determine the most beneficial arrangement. The rail marshalling yards were pushed away from the town centre to eliminate segregation of the township, and the vehicle stacking yards were moved closer to the town to encourage movement between the town and port.  (iii) Architectural : The architectural design of the Ferry Terminal uses inspiration from historic narratives and case study analysis from iconic ferry terminals around the world such as Naoshima ferry terminal, White Bay Cruise terminal and Vancouver Cruise terminal. The architectural scale also consists of three other key design elements that enhance the journey from terminal to town a drawbridge, a designed town edge and a redevelopment of the Edwin fox museum. These three structures are positioned on key pathways for community and social interaction. The three scales above identify individual key drivers of each scale in the design. The thesis argues that the introduction of a “new” ferry terminal coupled with a new urban design framework could improve connectivity between the ferry and the township transforming Picton into a more dynamic, economically viable township.</p>

The Taranaki Basin is well known for studies examining the seismic stratigraphy, depositional and erosional features, and tectonic frameworks linked to the New Zealand (NZ) continent. This particular study examines a “funny looking thing” (FLT) which we associate to be consistent with that of a braided channelized system. We observe this feature within the 3D Nimitz Survey (See Figure 1), located in the Northern Taranaki Basin (NTB) off the western continental coast of North Island, NZ. The FLT occurs within Quaternary deposits of the Whenuakura Formation which are interpreted to reflect shelfal topset sediments (O’Leary et al., 2010). It is underlain by the Giant Foresets Formation (GFF) of Pliocene to Pleistocene age, which are described as large-scale progradational and aggradational continental successions that migrated west to northwest in basinward direction (Anell and Midtkandal, 2017; Clairmont et al., 2020; Hansen and Kamp, 2002; Shumaker et al., 2017) (Figure 2). It comprises a shelf-to-slope succession of claystone to siltstone with argillaceous sandstone intervals defining an overall coarsening upward succession (O’Leary et al., 2010). The FLT within the Whenuakura Formation is characterized by chaotic facies in cross section, which shares characteristics with potential mass wasting events (Figure 3a). However, further analysis using seismic attributes improved the spatial and stratigraphic architecture of the FLT, which favored a complex channelized system interpretation over a mass transport deposit complex.

The need for deploying fast-charging stations for electric vehicles (EVs) is becoming essential in recent years. This need is justified by the increasing charging demand and supported by new charging technologies making EV chargers more efficient. In this paper, we provide a survey on EV fast-charging models and introduce a data-driven approach with an optimization model for deploying EV fast-chargers for both electric vehicles and heavy trucks traveling through a network of suburban highways. This deployment aims at satisfying EV charging demands while respecting the limits imposed by the electric grid. We also consider the availability of local photovoltaic (PV) farm and integrate its produced power to the proposed charging network. Finally, through a case study on Paris-Saclay area, we provide locations for EV charging stations and analyze the benefits of integrating PV power at different prices, production costs and charging capacities. The obtained results also suggest potential enhancements to the charging network in order to accommodate the increasing charging demand for EVs in the future.

AbstractThis paper introduces a set of descriptors applied to weather regimes, that allow for a detailed monitoring of the location and intensity of their atmospheric centers of action (e.g. troughs and ridges) and the gradients between them, when applicable. Descriptors are designed to document the effect of climate variability and change in modulating the character of daily weather regimes, rather than merely their occurrence statistics.As a case study, the methodology is applied to Aotearoa New Zealand (ANZ), using ERA5 ensemble reanalysis data for the period 1979-2019. Here, we analyze teleconnections between the regimes and their descriptors, and large-scale climate variability. Results show a significant modulation of centers of action by the phase of the Southern Annular Mode, with a strong relationship identified with the latitude of atmospheric ridges. Significant associations with El Niño Southern Oscillation are also identified. Modes of large-scale variability have a stronger influence on the regimes’ intrinsic features than their occurrence. This demonstrates the usefulness of such descriptors, which help understand the relationship between mid-latitude transient perturbations and large-scale modes of climate variability.In future research, this methodological framework will be applied to analyze (i) low-frequency changes in weather regimes under climate change, in line with the southward shift of storm tracks, and (ii) regional-scale effects on the climate of ANZ, resulting from interaction with its topography.
