A Design Science Research Approach to Smart and Collaborative Urban Supply Networks
Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness.
A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense.
Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

sabrın sonucu olarak ortaya çıkan yapıt başarıyı daha da yukarı seviyelere çıkaracaktır
Managing global virtual teams in the London FinTech industry
Today, the number of organisations that are adopting virtual working arrangements has exploded, and the London FinTech industry is no exception. During recent years, FinTech companies have increasingly developed virtual teams as a means of connecting and engaging geographically dispersed workers, lowering costs, and enabling greater speed and adaptability.
As the first study in the United Kingdom regarding global virtual team management in the FinTech industry, this DBA research seeks answers to the question, “What makes for the successful management of a global virtual team in the London FinTech industry?”. Straussian grounded-theory method was chosen as this qualitative approach lets participants have their own voice and offers some flexibility. It also allows the researcher to have preconceived ideas about the research undertaking.
The research work makes the case for appreciating the voice of people with lived experiences. Ten London-based FinTech Managers with considerable experience running virtual teams agreed to take part in this study. These Managers had spent time working at large, household-name firms with significant global reach, and one had recently become founder and CEO of his own firm, taking on clients and hiring contract staff from around the world. At least eight of the other participants were senior ‘Heads’ of various technology teams and one was a Managing Director working at a ‘Big Four’ consultancy. They had all (and many still did) spent years running geographically distributed teams with members as far away as Pacific Asia and they were all keen to discuss that breadth of experience and the challenges they faced.
Results from these in-depth interviews suggested that there are myriad reasons for a global virtual team, from providing 24 hour, follow-the-sun service to locating the most cost-effective resources with the highest skills. It also confirmed that there are unique challenges to virtual management and new techniques are required to help navigate virtual managers through them.
Managing a global virtual team requires much more than the traditional management competencies. Based on discussion with the respondents, a set of practical recommendations for global virtual team management was developed and covered a wide range of issues related to recruitment and selection, team building, developing standard operating procedures, communication, motivation, performance management, and building trust
Deposição de filmes do diamante para dispositivos electrónicos
This PhD thesis presents details about the usage of diamond in electronics. It presents a review of the properties of diamond and the mechanisms of its growth using hot filament chemical vapour deposition (HFCVD). Presented in the thesis are the experimental details and discussions that follow from it about the optimization of the deposition technique and the growth of diamond on various electronically relevant substrates. The discussions present an analysis of the parameters typically involved in the HFCVD, particularly the pre-treatment that the substrates receive- namely, the novel nucleation procedure (NNP), as well as growth temperatures and plasma chemistry and how they affect the characteristics of the thus-grown films. Extensive morphological and spectroscopic analysis has been made in order to characterise these films.Este trabalho discute a utilização de diamante em aplicações electrónicas.

THE DREAM OF A ZERO WASTE SOCIETY: EXPLORING THE PRACTICES AND BEHAVIOURS OF WASTE GENERATION IN GREATER MEXICO CITY
This research aims to re-conceptualise consumption and waste generation through a broader set of theoretical questions and analytical methodologies to establish a more holistic theoretical framework for comprehending the global South's "waste crisis." This thesis is primarily based on the following question: "why do we dispose of things?". By
focusing on practices and behaviours of consumption and disposal by citizens of GMC, this thesis seeks to unpack the networks, symbols, skills, and meanings of these practices.
This moves the conceptualisation of waste generation away from being conceived as an irremediable consequence of population growth or as primary responsibility on the
consumers' shoulders. Therefore, this thesis proposes that consumers are embedded in a "throwaway environment" that pushes them toward unsustainable practices. However, this does not mean that the consumers have a "throwaway culture"; consumers might be "carriers" of practices, but they are still active participants.
By unravelling the multiple layers of framing that aggregate into the consumption and disposal of citizens in GMC, we shall see how GMC society's historical, social, and political framework serves as dispositions that guide an individual to act. This study focuses on modifying the narrative of considering consumers as careless, lazy, or
consumption-driven. It also sheds light on how ignoring these behaviours and practices will only bring temporary and reactionary solutions when dealing with waste.
This dissertation also offers an analytical framework that explores how consumers' elements interrelate and are synergetic. By re-conceptualising consumption and waste
generation, I propose not focusing on the insidious moral narrative of whether consumption and disposal are acceptable and to what degree. Instead, we should concentrate on a policy strategy that will help reduce the flow of materials. As a result, we might be able to curve a waste crisis by accepting shared responsibility (mostly borne by governments and businesses
B/order work: recomposing relations in the seamful carescapes of health and social care integration in Scotland
As people, ageing and living with disabilities, struggle with how care is enacted through their lives, integrated care has gained policy purchase in many places, especially in the United Kingdom. Accordingly, there have been various (re)forms of care configurations instigated, in particular, promoting partnership and service redesign. Despite integrations apparent popularity, its contribution to improved service delivery and outcomes for people has been questioned, exposing ongoing uncertainties about what it entails and its associated benefits. Nonetheless, over decades, a remarkably consistent approach to integrated care has advanced collaboration as a solution. Equally, any (re)configurations emerge through wider infrastructures of care, in what might be regarded as dis-integrated care, as complex carescapes attempt to hold and aporias remain.
In 2014, the Scottish Public Bodies (Joint Working) (Scotland) Act mandated Health and Social Care Integration (HSCI), as a means to mend fraying carescapes; a flagship policy epitomising public service reform in Scotland, in which normative aspirations of collaboration are central. What then are the accomplishments of this ambitious legislation? From the vantage point of 2021, HSCI has been assessed as slow and insubstantial, but this is not the complete picture. Narratives about failing to meet expectations obscure more complicated histories of cooperation and discord, successes and failures, and unintended consequences. Yet given collaborative ubiquity, if partnerships are contested how then are they practiced?
To answer this question, I embarked on an interorganisational ethnography of the enactment of a Health and Social Care Partnership (HSCP), which went ‘live’ on April 1st, 2016; in a place I call ‘Kintra’. I interrogate what happened when several managers (from the NHS and Council) endeavoured to implement HSCI according to the precepts of the Act; working to both (re)configure and hold things together behind care frontiers; away from the bodywork of direct care, immersed in everyday arrangements in the spaces of governance and operations. I chart their efforts to comply with regulations, plan, and build governance apparatuses through documents. I explore through coalescent objects how distributed forms of governance, entwined in policy implementation, were subsequently both sustained, and challenged. I observed for seven months actors struggling to (re)configure care services embedded in a collaborative approach, as well as establish the legitimacy of the HSCP; exemplified through the fabrication of what was understood as a 'must-do' commissioning plan.
In tracing documents, I show the ways in which HSCI was simultaneously materialised and constituted through documentation. I reveal how, in the mundane mattering of document manufacturing, possibilities for (re)forming the carescape emerged. By delving into inconspicuous, ‘seamful’ b/order work that both sustained distinctions between the NHS and Council and enabled b/order crossings, I expose how actors were knotted, and how this shaped efforts to recompose the contours of the carescape.
While ‘Kintra’s story might be familiar, situated in concerns that may resonate across Scotland; I reveal how collaboration-as-practice is tangled in differing organisational practices, emerging from quotidian intra-actions in meeting rooms, offices, car parks and kitchenettes. I deploy a posthuman practice stance to show not only the way in which public administration ‘does’ care, but it’s world-making through a sociomaterial politics of anticipation.
I was told legislation was the only way to make HSCI in ‘Kintra’ happen, nevertheless, there was resistance to limit the breadth and depth of integrating. Consequently, I show how the (re)organising of b/orders was an always-ongoing act of maintenance and repair of a (dis)integrating carescape; as I learnt at the end of my fieldwork, ‘it’s ‘Kintra, ‘it’s aye been!
Infrastructure for the Circular Economy: The Role of Policy in System Change
The concept of a Circular Economy has gained policy traction as a mainstream solution for preserving and
renewing. This work sought to understand which policy instruments have been successful, might still be
necessary, and are most likely in the future to deliver a high penetration Circular Economy for materials, wastes
and associated energy. Waste related policy decisions in England over the past 20 years were reviewed,
exploring the regulatory means that had achieved the current 44% diversion of municipal wastes from landfill.
The hypothesis is that to achieve a far-reaching Circular Economy, at a greater scale, across different sectors
and for a wider product range, suitable physical infrastructure (waste treatment assets) must be available to
circulate those materials in the economy. Furthermore, the study set out to value financially and in terms of
social and economic benefits that could be derived from a circular approach across the whole economy. We
found the financial value to be significant at circa 1.5% of English GDP or 32bn and 72,000-175,000 jobs. It
was demonstrated by calculation that DEFRA analysis (for England) underestimated the capacity gap for
infrastructure by 11.3 million tonnes per annum in 2014.
The policy findings were that the early implementation of blunt instruments such as a landfill tax and separate
collection of recyclables did allow for diversion performance of approximately 45-50% recycling and
composting, the remaining 50% of which was progressively treated by energy from waste rather than landfill.
It is apparent that policies that drive system changes are effective in bringing about ecological transformations
of how societies, economies, and governments operate at all levels. This ecological transformation is
undoubtedly difficult to achieve since it will require consumers, manufacturers, regulators, policymakers,
media, and business all to move differently and together, but nevertheless it is critical at a global scale.Open Acces
Fast forward: technography of the social integration of connected and automated vehicles into UK society
The emerging connected and automated vehicles (CAV) have caught much research attention in the past few years. However, a techno-centric bias in the CAV research domain implies the lack of in-depth qualitative studies. To fill the gap, this Ph.D. project bridges the fields of Social Anthropology with STS by adopting technography, an ethnography of technology, to enable a thick description of the CAV technology’s social integration into UK society. By critically drawing a holistic view of the ongoing process of the CAV social deployment, it aims to (1) unfold CAV’s potential problems and dynamic contributions to everyday life through the lens of sociotechnical imaginaries, and (2) reveal and analyse the institutional practice on its social rollout.
Based on pilot research and one-year-long fieldwork in London and Edinburgh, the thesis investigated a wide range of important socio-political aspects where fundamental topics such as trust, human-and-machine relationship, social safety, political transparency, and equity in transport systems were explicated. Different from the planners’ top-down CAV imaginaries that focused on its contribution to functional safety, environment, and the economy, the public’s bottom-up imaginaries highlighted issues that were related to their travelling experiences, such as inequity of transport service distribution and sexual harassment during commutes. These findings inspired thinking and rethinking on what constitutes the success of technology’s social deployment from multiple perspectives. In particular, it critically pointed out that safety means not only technological feasibility but also social safety that refers to a safe commuting environments. Such finding in my thesis thus suggests that CAV technology is not a one-size-fits-all solution to problems in our transport system and calls for research effort to the broader socio-political and ethical areas of this technology. through an investigation of the institutional practice, it identified four major institutional forces, including technicians, industry stakeholders, researchers, and policymakers who have been working on these aspects with different approaches and priorities. Apart from acknowledging their efforts in building safety cases, pushing forward the CAV legislation, and engaging the public in trials, it critically explained challenges such as technical uncertainty and political tension in developing and implementing a legal framework.
Hence, the project contributes to an understanding of a close encounter between the CAV technology and its imaginaries, in which, technical and socio-political problems and potentials fabricate the richness in its social deployment. It also explicates the importance of embracing multiple perspectives and calls for continuous research in this field
