Developing a business innovation perspective of electric vehicle uptake: lessons from Milton Keynes' electric vehicle programme
Electrification of transport forms a major part of British policy for energy and climate change. The formation of the early market for Electric Vehicles (EVs) has been supported through consumer subsidies, regulatory support, and programmes for the deployment of electric vehicle charging infrastructure, but uptake does not seem to be proceeding at the rate needed for meeting policy objectives.
The approach pursued by policy actors is consistent with the approach of Strategic Niche Management (SNM), which would call for the creation of protected spaces to facilitate the development of new sociotechnical configurations. The Plugged-in Programme (PiP) in Milton Keynes is an example of creating a protective space. A comparison of PiP and other case studies in the literature of sociotechnical transitions identified a gap in SNM that may shed light on the limitations of EV policy in the UK. Traditionally, SNM has been used to monitor and manage interventions in support of prototype or pre-production vehicles. In consequence, there is no precedent for its application in support of early market technologies.
The market introduction of innovative technologies can trigger interrelated technological and behavioural changes, affecting the preferences of producers and consumers while altering the demand structure of the sector. However, SNM does not account for the patterns of use and demand implied in what remain largely technological templates for the future.
This thesis begins to develop a framework for the analysis and management of early market strategic niches. Insights from a second discipline, that of social marketing, were sought to complement the analytical tools of SNM. Social marketing is useful for understanding the effect of behavioural and market factors on the adoption of innovative technologies. Social marketing provides a framework for analysing and influencing behaviour in socially beneficial directions. Behaviour and choice are modulated through the application of a marketing orientation, identifying and addressing needs and creating valuable offerings.
This research is centred on organizational users of electric vehicles (EVs), and explores the effectiveness of the policy portfolio for addressing the needs of early adopters and for building an early market for EVs. Thematic analysis, a form of qualitative content analysis, is applied to evidence from documentary sources, participant observation and interviews with key organizational actors in the community of pioneering and prospective EV users. The analysis draws on concepts from SNM and social marketing to explore previously neglected forces affecting the early market for EVs, with particular focus on the increasing importance of market selection and the competition presented by an entrenched but socially undesirable incumbent.
Contrary to the expectations of policy actors, financial incentives and infrastructure deployment have a limited impact on the choices made by organizational actors. This thesis shows that the processes of learning and embedding that take place within the niche need to be multidimensional. Before a choice can be made, pioneering and prospective adopters of EVs invest considerable effort in the collaborative construction of new patterns of use and demand. This process can be supported by empowering interventions that identify suitable applications (creating multiple sub-niches within the niche) and facilitate the co-construction of new, competitive configurations around them. The models and networks created through this multidimensional, collaborative process translate into capabilities that give distinct advantages to pioneering adopters, allowing them to expand beyond their original niche and outperform the incumbents in mainstream markets
Using a Time-based Subarray Method to Extract and Invert Noise-derived Body Waves at Long Beach, California
The reconstruction of body waves from the cross‐correlation of random wavefields has recently emerged as a promising approach to probe the fine‐scale structure of the Earth. However, because of the nature of the ambient noise field, the retrieval of body waves from seismic noise recordings is highly challenging and has only been successful in a few cases. Here, we use seismic noise data from a 5,200‐node oil‐company survey to reconstruct body waves and determine the velocity structure beneath Long Beach, California. To isolate the body wave energy from the ambient noise field, we divide the entire survey into small‐aperture subarrays and apply a modified double‐beamforming scheme to enhance coherent arrivals within the cross‐correlated waveforms. The resulting beamed traces allow us to identify clear refracted P waves traveling between different subarray pairs, which we then use to construct a high‐resolution 3D velocity model of the region. The inverted velocity model reveals velocity variations of the order of 3% and strong lateral discontinuities caused by the presence of sharp geologic structures such as the Newport‐Inglewood fault (NIF). Additionally, we show that the resolution that is achieved through the use of high‐frequency body waves allows us to illuminate small geometric variations of the NIF that were previously unresolved with traditional passive imaging methods

Humans, robots and artificial intelligences reconfiguring urban life in a crisis
Autonomous urban robots were introduced in Milton Keynes (MK), UK, in 2018 to automate on-demand grocery delivery. Two years later the COVID-19 pandemic rendered routine activities such as delivering groceries or visiting the supermarket unexpectedly unsafe for humans. The ensuing disruption provided opportunities to investigate the potentialities of robotic and autonomous systems to provide cities with resources for coping with unexpected situations such as pandemics, heatwaves and blizzards and ultimately to transform and reinforce urban flows, leading to new ways of living in the city that arise as a result of emerging human-robot constellations. The crisis accelerated the ongoing transformation in human-robot relationships and made its tensions and potentials visible. The case of MK suggests that the cognitive capabilities of urban AIs are not to be found exclusively in computer bits and human neurons but arise from encounters and contexts, with institutions, policies, practices and even the materiality of the city itself being crucial to the emergence of urban AI

Social Media and Cities: a case-study based analysis of how digital life influences the urban physical environment
Social media influence materialises in the physical world by shaping our urban environment and changing the modality we experience. This under-explored outcome still lacks the conceptual tools to build a discourse around it. We present a case study that showcases how urban planning and development are influenced by social media and a first framework addressing the interrelation between social media, urban design, and the experience of the urban environment. This short contribution provides concepts for critically analysing the physical implications of social media-based ubiquitous hypertext systems

Demand Responsive Transport: is Milton Keynes developing a post-Covid revolution in public transport?
Recently there has been a renewed interest in Demand Responsive Transport (DRT) and related service offerings as a system that can serve 21st century patterns of dispersed low-density travel. Numerous attempts have been made to introduce forms of DRT, but despite some limited applications, DRT has largely stalled amidst technological, regulatory, and economic barriers.
Significantly, the impetus for DRT is now from technology-led companies that have already impacted upon taxi operations and have ambitions to develop their products and markets taking them into mainstream public transport, and some more innovative UK authorities are developing partnerships with these new digital technology operators. This has been accelerated by the pandemic creating uncertainty about how public transport use will change, coupled with local authorities seeking economic and social recovery amidst financial pressures on public transport support.
This paper reports some results from an in-depth case study of one city’s radical shift towards replacing conventional bus routes with DRT. This is the partnership between the commercial DRT operator, Via, and Milton Keynes Council. In autumn 2020 an area served by one Council supported bus route was converted to DRT and from April 2021 eleven other supported routes in Milton Keynes were replaced with DRT, run by Via and largely operated using electric vehicles. With a growing fleet of 26 vehicles covering the whole of Milton Keynes Borough, this represents the most widespread urban DRT application in the UK.
This paper draws on documentary evidence, operational data and in-depth interviews with key stakeholders, focussing on the operational, business and policy aspects of the system and how it may develop. Key public policy issues are identified in the cost-effective use of DRT, user adaptations and understandings needed, the partners and expertise required, and practices and relationships needed between actors for DRT to have a socially transformative effect on how public transport is provided and is used
Dimensions of Religiousness and Cancer Screening Behaviors among Church-Going Latinas
Churches are a promising setting through which to reach Latinas with cancer control efforts. A better understanding of the dimensions of religiousness that impact health behaviors could inform efforts to tailor cancer control programs for this setting. The purpose of this study was to explore relationships between dimensions of religiousness with adherence to cancer screening recommendations among church-going Latinas. Female Spanish-speaking members, aged 18 and older from a Baptist church in Boston, Massachusetts (N = 78), were interviewed about cancer screening behaviors and dimensions of religiousness. We examined adherence to individual cancer screening tests (mammography, Pap test, and colonoscopy), as well as adherence to all screening tests for which participants were age-eligible. Dimensions of religiousness assessed included church participation, religious support, active and passive spiritual health locus of control, and positive and negative religious coping. Results showed that roughly half (46 %) of the sample had not received all of the cancer screening tests for which they were age-eligible. In multivariate analyses, positive religious coping was significantly associated with adherence to all age-appropriate screening (OR = 5.30, p \u3c .01). Additional research is warranted to replicate these results in larger, more representative samples and to examine the extent to which enhancement of religious coping could increase the impact of cancer control interventions for Latinas
