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
The development of the Kent coalfield 1896-1946
One of the unique features of the Kent Coalfield is that it is entirely concealed by newer rocks. The existence of a coalfield under southern England, being a direct link between those of South Wales, Somerset and Bristol in the west and the Ruhr, Belgium. and northern France in the east, was predicted by the geologist R. A. C. Godwin-Austen as early as 1856. It was, however, only the rapid increase in demand for Britain's coal in the last quarter of the nineteenth century that made it worth considering testing this hypothesis. The first boring was made in the years 1886-90, and although it discovered coal, this did not in itself prove the existence of a viable coalfield. This could be done only by incurring the heavy cost of boring systematically over a wide area. As the financial returns from such an undertaking were uncertain, it was not surprising that in the early years, around the turn of the century, a dominant role was played by speculators, who were able to induce numerous small investors to risk some of their savings in the expectation of high profits. As minerals in Britain were privately owned, the early pioneer companies not only had to meet the cost of the exploratory borines, but also, if they were not to see the benefit of their work accrue to others, lease beforehand the right to mine coal from local landowners in as much of the surrounding area as possible. This policy was pursued most vigorously by Arthur Burr, a Surrey land specula tor, who raised capital by creating the Kent Coal Conoessions Ltd. and then floating a series of companies allied to it. Burr's enterprise would probably have been. successful had it not been for the water problems encountered at depth in -v- the coalfield. As a result, the Concessions group found itself in control of most of the coalfield, but without the necessary capital to sink and adequately equip its 01ffi collieries. By 1910, however, the discovery of iron ore deposits in east Kent, coupled with the fact that Kent coal was excellent for coking purposes, began to attract the large steel firms of Bolckow, Vaughan Ltd. and Dorman, Long & Co. Ltd. in to the area. The First World War intervened, however, to delay their plans, and to provide an extended lease of life to the Concessions group, which, by the summer of 1914, was facing financial collapse. By the time Dorman, Lone & Co, in alliance with Weetman Pearson (Lord Cowdray), had acquired control over the greater part of the coalfield from the Concessions group, not only was the country's coal industry declining, but so was its steel industry, which suffered an even more severe rate of contraction during the inter-war years. As a result, Pearson and Dorman Long Ltd. was forced to concentrate just on coal production, and this in turn was hampered not only by the water problems, but also by labour shortages and the schemes introduced by the government in 1930 to restrict the country's coal output, in an attempt to maintain prices and revenue in the industry. Nevertheless, production did show a substantial increase between 1927 and 1935, after which it declined as miners left the coalfield to return to their former districts, where employment opportunities were improving in the late thirties. Supporting roles were played in the inter-war years by Richard Tilden Smith, a share underwriter turned industrialist with long standing interests in the coalfield, who acquired one of the Concessions group's two collieries, and by the Powell Duffryn Steam Coal Co. Ltd., which through subsidiary companies, took over the only colliery to be developed by a pioneer company outside the Concessions group. The impossibility of Kent coal, because of its nature, ever gaining more than token access to the more lucrative household market, and then the failure of the local steel industry to materialise meant that the -vi- companies had to develop alternative outlets for their growing outputs. Although nearness to industrial markets in the south-east of England did confer certain advantages were poor consolation for the hoped for developments of either the early pioneers or the later industrialists. Instead of the expected profits, the companies mostly incurred losses, and only the company acquired by Powell Duffryn ever paid a dividend to its shareholders in the years before nationalisation. From the point of view of the Kent miners, the shortage of labour in the coalfield, particularly in the years 1914-20 and 1927-35, was to an important extent responsible for their being amongst the highest paid in the industry. At the same time the more favourable employment opportunities prevailing in Kent compared with other mining districts enabled the Kent Nine Workers Association to develop into a well organised union, which on the whole was able to look after the interests of its members fairly successfully. Throughout the period 1896 to 1946 the Kent Coalfield existed very much at the margin of the British coal industry. Its failure to develop substantially along the lines envisaged by either the early pioneers or by the later industrialists meant that its importance in national terms always remained small
Review of Methodologies to Assess Bridge Safety During and After Floods
This report summarizes a review of technologies used to monitor bridge scour with an emphasis on techniques appropriate for testing during and immediately after design flood conditions. The goal of this study is to identify potential technologies and strategies for Illinois Department of Transportation that may be used to enhance the reliability of bridge safety monitoring during floods from local to state levels. The research team conducted a literature review of technologies that have been explored by state departments of transportation (DOTs) and national agencies as well as state-of-the-art technologies that have not been extensively employed by DOTs. This review included informational interviews with representatives from DOTs and relevant industry organizations. Recommendations include considering (1) acquisition of tethered kneeboard or surf ski-mounted single-beam sonars for rapid deployment by local agencies, (2) acquisition of remote-controlled vessels mounted with single-beam and side-scan sonars for statewide deployment, (3) development of large-scale particle image velocimetry systems using remote-controlled drones for stream velocity and direction measurement during floods, (4) physical modeling to develop Illinois-specific hydrodynamic loading coefficients for Illinois bridges during flood conditions, and (5) development of holistic risk-based bridge assessment tools that incorporate structural, geotechnical, hydraulic, and scour measurements to provide rapid feedback for bridge closure decisions.IDOT-R27-SP50Ope
Northern Powerhouses: the homes of the industrial elite, c.1780-1875
This thesis explores the world of the industrial elites of Manchester and Liverpool in the period c.1780-1875, through their houses. The homes of the industrial elites, namely merchants and manufacturers, were extremely important tangible communicators of wealth, taste, and comfort. Whilst status-building was closely connected to the house, this thesis argues that the industrial elites carved their own identities into their domestic spheres and that emulation was not solely linked with aspiration.
The findings of this thesis are based around its three research aims regarding the changing location of houses in Manchester and Liverpool in the eighteenth and nineteenth centuries, the appearance and use of houses, and the daily routines and involvement of the industrial elite in their domestic routines. An analysis of elite residential patterns in Manchester and Liverpool across the eighteenth and nineteenth centuries has created a more nuanced look at urban geographies of the region in this period. Though some residential patterns differed because of economic and political structure, a key finding has been that the process of suburbanisation in and around Manchester and Liverpool commenced earlier than previous scholarship has suggested. Suburbanisation among the elites began in the latter decades of the eighteenth century and into the early decades of the nineteenth century, with elite suburban communities being firmly established by the 1820s.
This thesis discovered that despite socio-economic and political differences, the industrial elites of Manchester and Liverpool used their houses, gardens, and landed estates in very similar ways. This was a result of conformity which arose from emulation at both a community-based level and the emulation and aspiration of elite, gentrified lifestyle. Also, the merchants and manufacturers analysed within this work were involved in their home at every level of domesticity, from the construction of the house to the financial management of the household, although this latter theme was often a cooperative effort between spouses and family members, adding more to our understanding of gender, domesticity, and familial relations. Through detailed case studies and a combination of sources, the private lives of the industrial elites have been revaluated and redefined, including showing how their houses functions metaphorically and in reality
On Maritime Digitalization in Emerging Environments
The purpose of this chapter is to propose a conceptual framework for implementation of advance info-communication technology and systems (ICT&S) across maritime cluster in emerging environments, with emphasis on some South-East European countries and South Africa. Smart implementation and adoption of the ICT&S in shipping and port management have been considered due to the Holtham’s & Courtney\u27s model (2010). Furthermore, particular attention is given to Blockchain-based Maritime Supply Chain System (BMSCS) conceptual model, which includes distributed relational database, smart contracts, and crypto-currency payment mechanism as main constructs. The document workflow management, financial processes, and device connectivity are considered as key scenarios in the blockchain model. The stakeholders, who play the role of traditional intermediaries in the goods and accompanied documents and data flows, including overall supervision of the processes between end nodes, that is, shippers and customers, are encompassed within the BMSCS scheme. Some strengthens and frailty of BMSCS are highlighted, along with the suggestions for further investigation in this field, with the aim of better understanding prospective benefits and challenges of blockchain more extensive deployment across maritime sector in the future, with emphasize on developing environments

After Creation: Intergovernmental Organizations and Member State Governments as Co-Participants in an Authority Relationship
This is a re-amalgamation of what started as one manuscript and became two when the length proved to be more than any publisher wanted to consider. The splitting consisted of removing what are now Parts 3, 4, and 5 so that the manuscript focused on the outcome-related shared beliefs holding an authority relationship together. Those parts were last worked on in 2018. The rest were last worked on in late 2021 but also remain incomplete.
The relational approach adopted in this study treats intergovernmental organizations and the governments of member states as co-participants in an authority relationship with the governments of their member states. Authority relationships link two types of actor, defined by their authority-holder or addressee role in the relationship, through a set of shared beliefs about why the relationship exists and how the participants should fulfill their respective roles. The IGO as authority holder has a role that includes a right to instruct other actors about what they should or should not do; the governments of member states as addressees are expected to comply with the instructions. Three sets of shared beliefs provide the conceptual “glue” holding the relationship together. The first defines the goal of the collective effort, providing both the rationale for having the authority relationship and providing a lode star for assessments of the collective effort’s success or lack of success. The second set defines the shared understanding about allocation of roles and the process of interaction by establishing shared expectations about a) the selection process by which particular actors acquire authority holder roles, b) the definitions identifying one or more categories of addressees expected to follow instructions, and c) the procedures through which the authority holder issues instructions. The third set focus on the outcomes of cooperation through the relationship by defining a) the substantive areas in which the authority holder may issue instructions, b) the bases for assessing the relevance actions mandated in instructions for reaching the goal, and c) the relative efficacy of action paths chosen for reaching the goal as compared to other possible action paths.
Using an authority relationship framework for analyzing cooperation through IGOs highlights the inherently bi-directional nature of IGO-member government activity by viewing their interaction as involving a three-step process in which the IGO as authority holder decides when to issue what instruction, the member state governments as followers react to the instruction with anything from prompt and full compliance through various forms of pushback to outright rejection, and the IGO as authority holder responds to how the followers react with efforts to increase individual compliance with instructions and reinforce continuing acceptance of the authority relationship. Foregrounding the dynamics produced by the interaction of these two streams of perception and action reveals more clearly how far intergovernmental organizations acquire capacity to operate as independent actors, the dynamic ways they maintain that capacity, and how much they influence member governments’ beliefs and actions at different times. The approach fosters better understanding of why, when, and for how long governments choose cooperation through an IGO even in periods of rising unilateralism
Evaluating the readiness of three States in the Northeastern United States to adapt important natural resources systems to climate change: practical and theoretical considerations
In the last decade, governments have made advances in the development and adoption of climate
adaptation programs. With the rise of these programs, scholarly efforts have emerged to assess
and evaluate their effectiveness and quality. Thus, researchers have developed and applied a
range of climate adaptation evaluation approaches to gauge adaptation progress. In this thesis, a
climate adaptation evaluation approach developed by Ford and King (2015) — the adaptation
readiness framework — was applied to assess the readiness of three Northeastern US States –
Massachusetts, New Hampshire, and Maine – to adapt the natural resources systems located
within their boundaries to climate change. To enable the adaptation readiness evaluation, the
indicators in the adaptation readiness framework were revised to fit the context of this study
shaped by scale and governmental system. Systematic reviews of the scholarly and grey
literature were pursued. The revised indicators were used for the coding of documents.
Indicators were then scored based on ordinal rankings. Results demonstrated that Massachusetts
had the highest level of climate adaptation readiness, New Hampshire the second highest and
Maine the lowest climate adaptation readiness. It was found that political leadership – one of the
factors in the framework – strongly correlates with climate adaptation readiness, and that high
levels of climate adaptation readiness are associated with government centralization. The
conceptual strengths of the framework include its ability to illuminate adaptation deficits, and
adaptation policy patterns and structures. Its weaknesses stem from the vagueness of the
underlying definition of adaptation. Rather than measuring adaptation progress, the adaptation
readiness framework measures the extent to which governments have established programs that
fall under the category of adaptation as “adjustments”
Cooking the wild: the role of the Lundayeh of the Ulu Padas, (Sabah, Malaysia) in managing forest foods and shaping the landscape
This thesis provides an account of the Lundayeh subsistence system as found in the villages of Long Pasia and Long Mio, situated in the Ulu Padas, Sabah. The research focuses on Lundayeh food and diet, describing the diversity of resources used and the importance of forest foods. Comparison with studies from elsewhere in Borneo suggests that there are many similarities between Lundayeh practices and those of other highland peoples. These data are used to critically examine the concepts of 'wild' and 'wilderness', considering whether these concepts are meaningful, either analytically or for the Lundayeh. Investigation of the way in which the Lundayeh manipulate and manage their resources suggests that they have had a profound influence on their environment. Consequently, the Ulu Padas cannot be described as a wilderness, nor its resources as wild. The extent to which the Lundayeh themselves construct the categories of 'wild' and 'cultivated' foods is investigated through examining how these resources are owned, and their different roles in the diet. These data suggest that the Lundayeh recognise that there is no simple dichotomy of 'wild' and 'cultivated', but rather, that there is a gradation between these two categories. There is also evidence to suggest that the Lundayeh do not consider any resources as wild, in the sense of being uninfluenced by people. The environmental perceptions of the Lundayeh are also investigated, and how these have been shaped by their particular way of life, history, beliefs and knowledge systems. It is apparent that for the Lundayeh, the Ulu Padas is a cultural landscape. However, this is changing, as a result of recent social and environmental changes. This thesis concludes by examining the impact of changing perceptions on how the Lundayeh are managing their environment, and on their attitudes towards conservation
