    Memory, heritage, and the post steel city: Mediating the transformation of Sheffield since 1990

    No full text
    This chapter examines the stakeholders involved in the mediation of Sheffield’s transition to a post Steel City from 1990 onward, considering three key case studies. The first focuses on the city’s Lower Don Valley, which was the site of the World Student Games in 1991. The urban planning company Sheffield Development Corporation (SDC), chaired by industrialist Hugh Sykes, had overseen the regeneration of Sheffield’s East End. Sykes was incredibly influential in crafting a vision of rebirth for Sheffield that centred on the introduction of retail and leisure. The SDC was a private company that had to collaborate with council leaders and departments, such as the Department for Education and Economic Development (DEED). The latter was crucial in selling the new vision of Sheffield being crafted by Sykes and the SDC in the early 1990s, using the World Student Games as an opportunity to show Sheffield’s new global confidence. The second case study focuses on the Sheffield One urban planning company in the early 2000s, a company in which Hugh Sykes was again influential, alongside public relations strategists. Sheffield One was focused on redeveloping the city centre, overseeing the completion of the Heart of the City regeneration programme and masterminding a new publicity campaign to convince both citizens and businesses of the potential for a New Retail Quarter. The final case study focuses on the new co-operative movements and independent businesses in the city in the 2010s that have taken on the role of urban regeneration. Specific attention is given to the project Leah’s Yard and the way in which it has embraced previous attempts to rebrand Sheffield, but doing so through the mythmaking process of memory, heritage, and independent craft making. The chapter makes use of sources held at the Sheffield City Archives, focusing on the records of the World Student Games, the Sheffield Development Corporation, and the Sheffield One partnership, alongside new promotional material for the Heart of the City II regeneration programme and the Leah’s Yard development. It primarily focuses on public relations material, as well as visual evidence (photographs and film footage), to consider the ways in which Sheffield’s transition to the post Steel City, and ultimately its deindustrialisation, was mediated to both the city’s citizens and to businesses and professionals outside of Sheffield in an attempt to convince them to relocate to the city. In doing so, the aim is to foreground the paradoxical nature of this process in which those ‘doing’ the mediating were simultaneously drawing upon Sheffield’s steel industry heritage, while also persistently searching for a new future and identity

    Room Temperature Hydrogenation of CO2 Utilizing a Cooperative Phosphorus Pyridone‐Based Iridium Complex

    The synthesis, characterization and application of a new complex, [Ir(κ2-P,N-6-DCyPon*)(COD)] (1), where 6-DCyPon* is the anionic species, 6-dicyclohexylphosphino-2-oxo-pyridinide, is reported herein. Complex 1 was found to be an active catalyst in the hydrogenation of CO2 at room temperature. The ligand, 6-DCyPon*, is derived via deprotonation of a novel pro-ligand, 6-DCyPon (6-dicyclohexylphosphino-2-pyridone) during the synthesis of 1. The ligand is shown to participate within the reversible hydrogenation of 1, via a cooperative process, in which the species, [IrH3(κ2-P,N-6-DCyPon)(COD)] (2), was spectroscopically characterized, where 1 reacts with two equivalents of H2

    Transient price setting in the era of automated systems – the ‘hands-on’ Hotel General Manager lives on!

    No full text
    Hotel pricing discussions seem to be increasingly dominated by automated revenue management and pricing systems without considering human interaction. Using grounded theory, this paper foregrounds the voice of 20 managers and exposes the complexities and realities of their involvement in price decision-making. A hybrid price decision-making process was discovered where the hotel general manager remains in control despite automation, due to their modus operandi to control the performance of their hotel by using their local market and customer knowledge in the pricing process. This indicates that for revenue management at hotel unit level, there is an often-unseen gap between theory and practice

    Object Detection in Heritage Archives using a Human-in-Loop Concept

    No full text
    The use of object detection has become common within the area of computer vision and has been considered essential for a numerous applications. Currently, the field of object detection has undergone significant development and can be broadly classified into two categories: traditional machine learning methods that employ diverse computer vision techniques, and deep learning methods. This paper proposes a methodology that incorporates the human-in-loop feedback concept to enhance the deep learning object detection capabilities of pre-trained models. These Deep Learning models were developed using a custom humanities and social science dataset that was obtained from the British Online Archives collections database

    On the Construction Methodology of Microabrasion-Corrosion Maps Using Theoretical Approaches

    Get PDF
    In the field of microabrasion-corrosion, there has been limited research progress in modelling the process due to the complex interplay between the two processes involved. One of the crucial developments in the field has been the microabrasion-corrosion maps based on experimental results. However, mathematical modelling to develop the maps has not been attempted before. This work aimed to construct mathematical models for predicting the microabrasion-corrosion rate for mild steel and pure titanium in aqueous slurry conditions. The methodology developed was used for the construction of microabrasion-corrosion maps. The maps were constructed in two forms: (1) regime maps that identify the underlying mechanisms of microabrasion-corrosion and (2) wastage maps that identify the magnitude of the wastage rate. The effects of abrasive particle size and solution pH were shown on the maps. These maps have not been reported before and can form a basis for material selection and process optimisation for various microabrasion-corrosion applications, such as hip joint conditions. The advantages and applications of these maps are addressed in this paper

    A review of recent control techniques of drooped inverter‐based AC microgrids

    Get PDF
    As the penetration of distributed generation (DG) systems in the grid is increasing, the challenge of combining large numbers of DGs in the power systems has to be carefully clarified and managed. The control strategy and management concept of the interconnected systems should be flexible and reliable to handle the various types of DGs. This can be suitably met by microgrids. This paper introduces the microgrid structure and elements and states the main objectives that should be achieved by the microgrid controllers and each DG controller in both operation modes (grid-connected and island mode). It also presents the challenges of having multiple DG units in a microgrid in terms of accurate power control/sharing, voltage and frequency regulation, power management between DGs, different renewable energy sources integration and deployment, seamless mode transfer, and the modeling issues. The centralized and decentralized control techniques as potential solutions have been discussed and compared by highlighting the advantages and disadvantages of each. Furthermore, the recent control techniques for drooped alternating current microgrids and the main proposed solutions and contributions in the literature have been exposed to finally overcome the droop control limitations and obtain a flexible and smart distributed power system

    Flash fiction as a distinct literary form: some thoughts on time, space, and context

    Get PDF
    This article combines a craft-focused approach with a stylistics perspective to consider the ways in which flash fiction may be said to operate as a unique literary form. In the opening section flash fiction is defined in relation to what are usually seen as its two closest literary companions: prose poetry and the short story. This is followed by an introduction to the linguistic phenomenon known as deixis, and to related concepts from the field of Narratology. These ideas are subsequently illustrated and explored through the close analysis of several short texts and used to uncover what might be considered the defining features of the form. The earlier taxonomic approach of William Nelles is also evaluated in the light of more recent creative practice. The article concludes by arguing that the mobilisation of a story world is a necessary requirement for a text to be classified as flash fiction, by highlighting the importance of deft manipulation of deictic elements, and finally by suggesting that the unique communicative context evoked by flash fiction has significant implications for its interpretation

    The entanglement of language and place in early childhood: a review of the literature

    Get PDF
    In this paper, the authors report the findings of a narrative review of extant international research literature to propose a conceptual model for how young children’s language is entangled with place. Educational policy, curriculum documents, and speech and language therapy assessments in England tend to frame children as placeless and treat the place where language happens as either irrelevant or a hindrance to the quality of their speech. Conducting a narrative review, with a particular attention to the role of affect in what they read, the authors identify and explore three emerging themes in the extant literature that resist this framing: (1) how children’s language emerges through place, (2) how place is re-signified and re-made through children’s language, and (3) how place reconfigures how children are heard. Across these themes, we consider how place implicates identity, power, and hierarchies of language and embodiment. The authors argue that educators, researchers, and others need to attend more carefully to how children’s language emerges where they talk, and to the politics of how language and place reproduce whiteness in relation to what is valued and what counts as language

    Learning from failure: A context‐informed perspective on RCTs

    Get PDF
    Discussions of randomised controlled trials (RCTs) in education that do not show an impact regularly focus on the intervention and how it failed to impact on expected measures, with typologies identifying persistent critical points of failure. This paper uses one such RCT—the Integrating English programme—to exemplify the application of a new model to explain failure in RCTs. To do so, the paper develops a set of categories of context drawing on the wider social evaluation field: backdrop, design, operation and interpretation. Thus, the paper exposes critical weak points in the commission and interpretation, as well as the implementation, of an RCT. Our aim is to work towards more robust evaluations by demonstrating that it is not simply the programme design, implementation and evaluation that can contribute to a lack of impact; there can be more fundamental system issues at play
