    Queen of All Islands : The Imagined Cartography of Matthew Paris\u27s Britain

    Get PDF
    In the middle decade of the thirteenth century, the Benedictine monk and historian Matthew Paris drew four regional maps of Britain. The monk\u27s works stand as the earliest extant maps of the island and mark a distinct shift from the cartographic traditions of medieval Europe. Historians have long considered the version attached to the monk\u27s Abbreviatio Chronicorum – the Claudius map – as the last and most thorough of Paris\u27s images of Britain. However, scholars have focused on the document\u27s limitations as an accurate geographic representation and have failed to consider critically Paris\u27s representation of Britain with an eye towards its political implications. This thesis is an examination of the elements of the Claudius map, in context with the monk\u27s historical writings, to argue that Paris\u27s map of Britain should be studied as an aggressive cultural artifact through which the monk posited imperial English claims to suzerainty over the whole of the island

    The isolation and the biochemistry of the animal protein factor

    Investigators are generally convinced by now that the animal protein factor is vitamin-Iike in nature. Experiments which have supplied the data for this report were initiated mainly for the purpose of isolating, purifying, and concentrating the animal protein factor, and to determine by biological means some of the chemical and physical properties of this vitamin-like substance. Fish solubles were used. The fuller\u27s earth eluate was broken down into various fractions, and these fractions were fed to chicks in order to determine the completeness by which each fraction was purified and the biological value of each fraction

    The Design of Not-so-everyday Things: Designing for Emerging Experiences

    Get PDF
    In this paper, we explore how emerging technologies and experiences challenge previous theories and practices to grow and adopt and, thus, address new and unique challenges, such as designing across macro-level ecosystems, new devices, and interaction models that enable user control of data in an increasingly complex digital world. We discuss these topics with respect to real and future examples, the unique challenges they present, and how academia and industry must collaborate to adapt current frameworks and develop new methods to address these challenges. This partnership will ensure both parties better understand the problem space for designing emerging experiences in today\u27s digital economy. Further, this partnership enables scholars and practitioners to more effectively explore the solution space for designing novel products and developing advanced theories that help craft meaningful user experiences. Finally, we argue that the partnership between academia and industry can develop future talent and upskill current practitioners, which is paramount in successfully meeting the challenges inherent in the design of emerging technologies

    Three victorian fictional images of volunteering

    Get PDF
    Fictional depiction of volunteering in the second half of the nineteenth century in Britain can, I believe, provide a commentary on social trends during this period of rapid changes in social action. The three novels I have chosen to illustrate this assertion (North and South, Tom Brown at Oxford, and Marcella) are considered in the chronological order in which they were published. The novelists, Elizabeth Gaskell, Thomas Hughes, and Mary Augusta Ward, as well as providing fictional models of what is involved in the life of a volunteer, provide insight into three different movements in the social theories underlying social action in the period. The novelists themselves were involved in volunteering and in its organisation, giving an extra dimension to the creation of their fictional world

    Herschel Observations of Debris Discs Orbiting Planet-hosting Subgiants

    Get PDF
    Debris discs are commonly detected orbiting main-sequence stars, yet little is known regarding their fate as the star evolves to become a giant. Recent observations of radial velocity detected planets orbiting giant stars highlight this population and its importance for probing, for example, the population of planetary systems orbiting intermediate mass stars. Our Herschel survey observed a subset of the Johnson et al program subgiants, finding that 4/36 exhibit excess emission thought to indicate debris, of which 3/19 are planet-hosting stars and 1/17 are stars with no current planet detections. Given the small numbers involved, there is no evidence that the disc detection rate around stars with planets is different to that around stars without planets. Our detections provide a clear indication that large quantities of dusty material can survive the stars' main-sequence lifetime and be detected on the subgiant branch, with important implications for the evolution of planetary systems and observations of polluted or dusty white dwarfs. Our detection rates also provide an important constraint that can be included in models of debris disc evolution.Comment: 12 pages, MNRAS, accepte

    The de Broglie Wave as a Localized Excitation of the Action Function

    Full text link
    The Hamilton-Jacobi equation of relativistic quantum mechanics is revisited. The equation is shown to permit solutions in the form of breathers (nondispersive oscillating/spinning solitons), displaying simultaneous particle-like and wave-like behavior adaptable to the properties of the de Broglie clock. Within this formalism the de Broglie wave acquires the meaning of a localized excitation of the classical action function. The problem of quantization in terms of the breathing action function is discussed.Comment: 11 page
