  1. Wofull newes from wales: local, national and transnational case studies

    Winston, Brian
    There is a basic, and erroneous, belief about the newsreel, ie it was ‘neither journalistic nor artistic’ (in the documentary sense). It can, though be argued that it was both but poorly so. It was, rather, facile journalism and uninspired documentary. And moreover it reflected centuries of efforts to illustrate the news, from woodcut and photography, to film, radio and television. Newsreels are not so easily dismissed.

  2. The cellular and pathologic prion protein

    Gill, Andrew; Castle, Andrew R.
    The cellular prion protein, PrPC, is a small, cell-surface glycoprotein with a function that is currently somewhat ill-defined. It is also the key molecule involved in the family of neurodegenerative disorders called transmissible spongiform encephalopathies, which are also known as prion diseases. The misfolding of PrPC to a conformationally-altered isoform, designated PrPSc, is the main molecular process involved in pathogenesis and appears to precede many other pathological and clinical manifestations of disease, including neuronal loss, astrogliosis and cognitive loss. PrPSc is also believed to be the major component of the infectious “prion”, the agent responsible for disease transmission, and preparations...

  3. Speech politics: performing political scripts

    Breed, Ananda
    I use the notion of speech politics from William B. Worthen’s consideration of how the written text or script and performance influence and inform the other as an evolving practice. (Worthen 2009) I make the argument that the rehearsal of the performance through the Gacaca play by Kalisa Rugano and several grassroots theatre associations that used theatre to rehearse and perform gacaca was influential in certain areas. Here, a critical gap between the written text or script and the performance of gacaca is made visible as the theatrical frame becomes a space to critically analyse some of these larger narratives...

  4. Street smarts for smart streets

    Coley, Rob
    In the technological imaginary of the ‘smart city’, new practices of visualizing protect against a multiplicity of forces that threaten to destabilize urban life. Computational urbanism promises access to a privileged and commanding perspective on the dynamics of the city. Critical responses to this speculative ideal tend to focus on how the exploitation of such a perspective might compromise the uniquely human character of urban relations. There is, however, a more radical implication of urban smartness, namely a situation in which living more intimately with nonhuman objects and processes reveals the humanist vision of the city to be both highly...

  6. A deep learning approach to anomaly detection in nuclear reactors

    Caliva, Francesco; De Sousa Ribeiro, Fabio; Mylonakis, Antonios; Demaziere, Christophe; Vinai, Paolo; Leontidis, Georgios; Kollias, Stefanos
    In this work, a novel deep learning approach to unfold nuclear power reactor signals is proposed. It includes a combination of convolutional neural networks (CNN), denoising autoencoders (DAE) and k-means clustering of representations. Monitoring nuclear reactors while running at nominal conditions is critical. Based on analysis of the core reactor neutron flux, it is possible to derive useful information for building fault/anomaly detection systems. By leveraging signal and image pre-processing techniques, the high and low energy spectra of the signals were appropriated into a compatible format for CNN training. Firstly, a CNN was employed to unfold the signal into either...

  7. Dark angels: Blake, Milton, and Lovecraft in Ridley Scott's Prometheus

    Whittaker, Jason
    William Blake has long been an influence in Ridley Scott’s work, most famously via the (mis)quotation of lines from Blake’s America by Roy Batty in Blade Runner and more extensively through the design work of Gorton Assheton and motifs based on “The Angel” and “The Sick Rose” in Legend, as well as drawing on Thomas Harris’s dialogue with Blake in the Hannibal Lecter trilogy. This chapter examines some of the ways in which Scott references Blake’s visual imagery in conjunction with the cosmologies of Milton and H.P. Lovecraft in his flawed but fascinating 2012 film, Prometheus.

  8. Sustainable development goals: law, theory and implementation

    French, Duncan; Kotze, Louis
    Building on the previously established Millennium Development Goals, which ran from 2000-2015, the 2015 Sustainable Development Goals (SDGs) provide the UN with a roadmap for development until 2030. This topical book explores the associated legal and normative implications of these SDGs, which in themselves are not legally binding. The 17 goals and 169 targets of the SDGs cover areas as crucial as poverty reduction, climate change, clean water and access to justice. Combining both thematic and goal-specific analysis, expert contributors establish the relevance not just of international law, but also of a broader range of normative frameworks including constitutional norms,...

  9. SDG 17: partnerships for the goals: cooperation within the context of a voluntarist framework

    French, Duncan; Cooper, Nathan John
    As the final Global Goal, SDG 17’s principal function is to establish partnerships in support of the achievement of the other Sustainable Development Goals. It includes targets in such areas as overseas development assistance, debt sustainability, technology transfer, capacity building, and international trade. It reflects a pattern set in the Millennium Development Goals, where the final goal is also the most instrumental, in that case MDG 8, which sought to establish a ‘Global Partnership for Development’. SDG 17 underscores the importance of cooperation in the attainment of global development, recognising more broadly that partnerships are fundamental to the achievement of...

  10. Rumex and Urtica detection in grassland by UAV

    Binch, Adam; Cooke, Nigel; Fox, Charles
    . Previous work (Binch & Fox, 2017) used autonomous ground robotic platforms to successfully detect Urtica (nettle) and Rumex (dock) weeds in grassland, to improve farm productivity and the environment through precision herbicide spraying. It assumed that ground robots swathe entire fields to both detect and spray weeds, but this is a slow process as the slow ground platform must drive over every square meter of the field even where there are no weeds. The present study examines a complimentary approach, using unmanned aerial vehicles (UAVs) to perform faster detections, in order to inform slower ground robots of weed location...

  11. Light and its interaction with antiquities and works of art: a conservator’s perspective

    Kotoula, Eleni
    This chapter addresses issues related to light–object interaction along with its resulting phenomena, taking into consideration materiality issues. It presents light and its role in artefacts studies, either as a tool for finds analysis or as a corrosion agent. It attempts a balanced investigation into past and contemporary approaches towards light from the conservator’s perspective. It discusses traditional raking and oblique light examination, along with its advanced digital analogue, Reflectance Transformation Imaging (RTI), which bridges the gap between digital photography and three-dimensional modelling. Applications of dome and/or Highlight RTI in a wide variety of material and artefact types, as well...

  13. Lifespan perspectives on psychological contracts

    Bal, M.; Vantilborgh, T.
    This chapter discusses the role of psychological contracts along the lifespan and careers of workers. It explains the meaning of the psychological contract, and discusses lifespan theories in relation to how psychological contracts may change with age. In particular, there are three ways through which psychological contracts evolve over time. First, the content of mutual obligations between employees and organizations may change over time, where older workers may perceive different obligations from themselves and their employer compared to younger workers. Second, the type and features of psychological contracts may change over time, with older workers generally experiencing more stable, yet...

  15. Reconciliation

    Romero, Teresa
    Accumulated evidence from studies on wild and captive populations shows that social animals use an array of behavioral mechanism mitigate the costs of aggression, generally labelled as conflict resolution mechanisms (Arnold, Fraser, & Aureli, 2010; Aureli & de Waal, 2000). Among them, reconciliation – i.e. friendly reunion of former opponents shortly after the end of a conflict – is probably the most efficient one, since it involves direct communication between involved individuals.

  17. The other door of the sanctuary: the apse and divine entry in the early Byzantine church

    Shilling, Brooke
    Beginning in the sixth century, theophanies of Christ conveyed by a mandorla of light or cloud rendered the apse conch as a point of entry for the divine in the church. At the same time, alternative pictorial devices were developed to convey the presence of the Virgin Mary in the church and sanctuary, while drawing greater attention to the apse conch as a threshold to be crossed. This chapter explores the form and function of these motifs in two early Byzantine apse mosaics on the island of Cyprus, in the churches of the Panagia Angeloktistos at Kiti and the Panagia...

  18. Electrical spinning to electrospinning: a brief history

    Ghosal, K.; Agatemor, C.; Tucker, N.; Kny, E.; Thomas, S.
    Fine fibers made by electrostatic force have been discussed, investigated, and patented for a long time starting already in the late 18th century. However, till the eighties of the 20th century, potential applications for such fibers were restricted by different technological limitations. In 1995, Doshi and Reneker reworked and simplified the electrical spinning process. The book begins with this journey, how the invention fuelled applications and also presents a short account on current status of electrospinning in diverse application field.

  19. Seats and sites of authority: British colonial collecting on the East African coast

    Longair, Sarah
    This chapter explores cultural interactions on the East African coast in the late nineteenth century through the story of two Swahili 'viti vya enzi' (chairs of power) which were collected and now reside in museums in Britain. The narratives of these two chairs expose both the cultural knowledge that the British had of Swahili culture but also how these objects changed in meaning as they shifted through time and space, and became objects of power for their new British owners.

  20. The "colonial moment" in the lives of objects from the Swahili coast

    Longair, Sarah
    During the era of British rule on the East African coast, a number of British colonial officials, wives and other figures acquired significant collections of Swahili material culture. Such objects might be displayed locally and later taken ‘home’, others were despatched to museums in Britain or, in the twentieth century, exhibited in the newly-created museums in East African territories. This essay will focus upon the ‘colonial moment’ in the lives of a selection of such objects from the Swahili coast, including ceramics, the kiti cha enzi of the Sultan of Witu and the ngoma of the Mwinyi Mkuu. It will...
