    An empirical investigation of the relationship between integration, dynamic capabilities and performance in supply chains

    Get PDF
    This research aimed to develop an empirical understanding of the relationships between integration, dynamic capabilities and performance in the supply chain domain, based on which, two conceptual frameworks were constructed to advance the field. The core motivation for the research was that, at the stage of writing the thesis, the combined relationship between the three concepts had not yet been examined, although their interrelationships have been studied individually. To achieve this aim, deductive and inductive reasoning logics were utilised to guide the qualitative study, which was undertaken via multiple case studies to investigate lines of enquiry that would address the research questions formulated. This is consistent with the author’s philosophical adoption of the ontology of relativism and the epistemology of constructionism, which was considered appropriate to address the research questions. Empirical data and evidence were collected, and various triangulation techniques were employed to ensure their credibility. Some key features of grounded theory coding techniques were drawn upon for data coding and analysis, generating two levels of findings. These revealed that whilst integration and dynamic capabilities were crucial in improving performance, the performance also informed the former. This reflects a cyclical and iterative approach rather than one purely based on linearity. Adopting a holistic approach towards the relationship was key in producing complementary strategies that can deliver sustainable supply chain performance. The research makes theoretical, methodological and practical contributions to the field of supply chain management. The theoretical contribution includes the development of two emerging conceptual frameworks at the micro and macro levels. The former provides greater specificity, as it allows meta-analytic evaluation of the three concepts and their dimensions, providing a detailed insight into their correlations. The latter gives a holistic view of their relationships and how they are connected, reflecting a middle-range theory that bridges theory and practice. The methodological contribution lies in presenting models that address gaps associated with the inconsistent use of terminologies in philosophical assumptions, and lack of rigor in deploying case study research methods. In terms of its practical contribution, this research offers insights that practitioners could adopt to enhance their performance. They can do so without necessarily having to forgo certain desired outcomes using targeted integrative strategies and drawing on their dynamic capabilities

    Innovation in Energy Security and Long-Term Energy Efficiency Ⅱ

    Get PDF
    The sustainable development of our planet depends on the use of energy. The increasing world population inevitably causes an increase in the demand for energy, which, on the one hand, threatens us with the potential to encounter a shortage of energy supply, and, on the other hand, causes the deterioration of the environment. Therefore, our task is to reduce this demand through different innovative solutions (i.e., both technological and social). Social marketing and economic policies can also play their role by affecting the behavior of households and companies and by causing behavioral change oriented to energy stewardship, with an overall switch to renewable energy resources. This reprint provides a platform for the exchange of a wide range of ideas, which, ultimately, would facilitate driving societies toward long-term energy efficiency

    Brain Computations and Connectivity [2nd edition]

    Get PDF
    This is an open access title available under the terms of a CC BY-NC-ND 4.0 International licence. It is free to read on the Oxford Academic platform and offered as a free PDF download from OUP and selected open access locations. Brain Computations and Connectivity is about how the brain works. In order to understand this, it is essential to know what is computed by different brain systems; and how the computations are performed. The aim of this book is to elucidate what is computed in different brain systems; and to describe current biologically plausible computational approaches and models of how each of these brain systems computes. Understanding the brain in this way has enormous potential for understanding ourselves better in health and in disease. Potential applications of this understanding are to the treatment of the brain in disease; and to artificial intelligence which will benefit from knowledge of how the brain performs many of its extraordinarily impressive functions. This book is pioneering in taking this approach to brain function: to consider what is computed by many of our brain systems; and how it is computed, and updates by much new evidence including the connectivity of the human brain the earlier book: Rolls (2021) Brain Computations: What and How, Oxford University Press. Brain Computations and Connectivity will be of interest to all scientists interested in brain function and how the brain works, whether they are from neuroscience, or from medical sciences including neurology and psychiatry, or from the area of computational science including machine learning and artificial intelligence, or from areas such as theoretical physics

    From food waste to transport biomethane, a comprehensive scenario-based waste to energy conversion pathway trade-off and whole systems modeling analysis

    Get PDF
    This thesis outlines the design of a novel methodological, Excel modelling and integrated whole systems analysis approach for elucidating key material, energy and financial cost-benefit trade-off arising from deployment of Food Waste (FW) to Transport biomethane conversion (FWtTBC) pathway across the Northern Powerhouse (NPH) city and metropolitan county regions and more specifically across Leeds city region which embodies a more in-depth case study analysis. To this end, the research established that real-world representative values for household FW collection and FW to biomethane conversion potential (45-90m3) to be sufficient across NPH city and metropolitan county regions to be financially self-sufficient for FWtTBC pathway deployment attributed to key revenue streams against deployment cost. Here the case-specific scenario study of FWtTBC pathway deployment at NPH Leeds city region using Malting Organics Treatment Facility demonstrated that there exists sufficient AD food waste capacity (50,000 tonnes) to accommodate FW collected from the entire population of Leeds city. Assessment of total revenue against cost of FWtTBC pathway deployment has returned a decent payback period of 2 to 10 years under realistic real-world operational conditions, whilst also having outlined the significant revenue contribution derived from RTFO and avoided FW landfill tax. It is consequently advised for such policies to remain in replace for the foreseeable future. Moreover, the research established a number of policy recommendations across each relevant chapter that is thought to be effective in mitigating key risk factors that could undermine successful pathway deployment either financially or operationally. Namely, these include policy recommendations to optimize household FW disposal and capture rate, FW supply flexibility and FW collection logistics in addition to those that endeavour to safeguard RTFC, biomethane sales and avoided FW landfill tax revenues. Future research should focus on using real-world operational data availability pertaining specifically to FWtTBC pathway deployment across a single or select few regions, which would enable the adopted modelling approach to achieve much greater specificity and accuracy in its intended findings and outcomes. It is hoped for the findings of this and future similar research to be used to support real-world FWtTBC pathway deployment in key regions of need, to help facilitate the actual real-world deployment process at any suitable scale of implementation

    Sport team leadership coaching and captaincy in elite level rugby union football

    Get PDF
    A wide range of literature exists on coaching but it is concerned predominantly with the high school and college levels, is based upon athlete or coach perceptions, or is confined to observations of training or competition. As leaders of sports teams, coaches and captains have rarely been studied at the highest level of national or international sports competition. In the present study, the team leadership roles of the coach and captain in elite rugby union football in New Zealand were examined using participant observation and other qualitative research methods. Elite was defined as New Zealand rugby’s highest internal level of competition: (a) the national provincial championships and (b) international test matches of the national team, the All Blacks. The study explored the roles of the elite rugby coach and captain in vivo in a wide variety of team situations. It was felt that this could provide first-hand information on particular team leader behaviours, on what a coach and captain actually do, and how they are perceived by those around them. The main objective, however, was to use grounded theory techniques to create a model of elite rugby team leadership that might guide developmental programmes on such leadership. The research phases undertaken were those of participant observation with a Provincial Team for five matches, a survey of provincial teams’ coaches and captains on their leadership associated with actual matches, three years’ participant observation with the All Blacks (including observation in eight test match weeks), multiple perspectives on elite team leadership from past rugby test players in New Zealand and overseas, and interviews with national team leaders in sports other than rugby. Participant observation, interviews, questionnaires and document analysis generated data from the research settings. These data were considered in terms of symbolic interactionism and subjected to a grounded theory process. This led to a set of elite rugby team leadership categories and properties which, in turn, generated a comprehensive set of theoretical propositions. The propositions became the basis for a model of elite rugby team leadership. This model was then considered as the basis for a programme to develop elite rugby team leaders. Significant aspects of the research findings which have not featured in previous research literature included the coach’s vision, team culture, centrality of the game plan, match week build-up, the importance of the captain’s playing example, the coach's ability to utilise teaching precepts, the coach’s personal qualities, and the need to develop and evaluate team leaders. The model, and the developmental programme principles emanating from it, are seen as relevant for developing elite level leaders in team sports other than rugby

    A Survey on Reservoir Computing and its Interdisciplinary Applications Beyond Traditional Machine Learning

    Full text link
    Reservoir computing (RC), first applied to temporal signal processing, is a recurrent neural network in which neurons are randomly connected. Once initialized, the connection strengths remain unchanged. Such a simple structure turns RC into a non-linear dynamical system that maps low-dimensional inputs into a high-dimensional space. The model's rich dynamics, linear separability, and memory capacity then enable a simple linear readout to generate adequate responses for various applications. RC spans areas far beyond machine learning, since it has been shown that the complex dynamics can be realized in various physical hardware implementations and biological devices. This yields greater flexibility and shorter computation time. Moreover, the neuronal responses triggered by the model's dynamics shed light on understanding brain mechanisms that also exploit similar dynamical processes. While the literature on RC is vast and fragmented, here we conduct a unified review of RC's recent developments from machine learning to physics, biology, and neuroscience. We first review the early RC models, and then survey the state-of-the-art models and their applications. We further introduce studies on modeling the brain's mechanisms by RC. Finally, we offer new perspectives on RC development, including reservoir design, coding frameworks unification, physical RC implementations, and interaction between RC, cognitive neuroscience and evolution.Comment: 51 pages, 19 figures, IEEE Acces
