    Shams al-dim al-Sakhawi as a historian of the 9th/15th century : with an edition of that section of his chronicles (Wajiz al-kalam) covering the period 800-849 / 1397-1445

    Although a prolific writer of history, Sakhawi is, primarily, a traditionist. As such, accuracy both in utterance and writing would, by the very nature of his training, be his first objective. Modern writers appear to have neglected the importance of his contribution to the understanding of the history of his century. accept for a few articles, comparatively little has been written. It is, therefore, strange that such a mine of information as Sakhawi's writing presents has remained so long in oblivion. In this thesis an attempt has been made to evaluate that contribution together with an edition of part of his work. The study has been divided into three sections, the first dealing with Sakhawi’s life and times. This part of the study is based largely on his autobiography which was written but a few months before he died. During research no reference was discovered to this most informative work. The section falls into three chapters, the first of which endeavours to show the political and educational aspects of Cairo during the early part of Sakhawi's lifetime. Cairo was his native city and, as such, made great impact on his early life. In the second chapter the position of his family, his Shaykhs, the academic journeys he made, his residence in Hijaz and the last phase of his life are portrayed. The third chapter deals with his activities as an adult, his reputation as a traditionist together with a survey of his works as presented in his autobiography. In the second part, the study deals exclusively with Sakhawi as a historian of the 9th/15th century. This part also is divided into two chapters, the first of which considers the following aspects: - I Sakawi's works on the century; II His motives, methods and literary style and III His treatment of the history of the century. The second chapter collates Sakhawi's methods of selecting his information and the painstaking efforts he made to verify them, together with his historical achievements, while the last two topics endeavour to evaluate his task as a historian in that century. Section three presents the hitherto unedited part of Wajiz al-Kalam... which deals with the history of the 9th/15th century. This section also falls into the three divisions of preface, text and annotations. The last divides again into two groups one of which deals with the textual variants mentioned in the footnotes and the other attempts to deal with the interpretation of most of the idiom, colloquial expressions and the names of places and personalities mentioned in the supplement to the text

    REDS: Random Ensemble Deep Spatial prediction

    No full text
    There has been a great deal of recent interest in the development of spatial prediction algorithms for very large datasets and/or prediction domains. These methods have primarily been developed in the spatial statistics community, but there has been growing interest in the machine learning community for such methods, primarily driven by the success of deep Gaussian process regression approaches and deep convolutional neural networks. These methods are often computationally expensive to train and implement and consequently, there has been a resurgence of interest in random projections and deep learning models based on random weights -- so called reservoir computing methods. Here, we combine several of these ideas to develop the Random Ensemble Deep Spatial (REDS) approach to predict spatial data. The procedure uses random Fourier features as inputs to an extreme learning machine (a deep neural model with random weights), and with calibrated ensembles of outputs from this model based on different random weights, it provides a simple uncertainty quantification. The REDS method is demonstrated on simulated data and on a classic large satellite data set

    Impact of Stand Your Ground, Background Checks and Conceal and Carry Laws on Homicide Rates in the U.S

    In recent years, the number of gun related killings appear to be on the rise. In fact, data show that gun related murders rose 32% between 2014 and 2017 (Gramlich 2019). While the second amendment to the U.S. Constitution allows citizens to bear weapons, many states have passed additional laws regulating the industry. These include restrictive and prohibitive laws. The goal of this paper is to assess the impact of changes in hand gun related legislation on firearm homicide rates in the United States for the period 1999-2015. More specifically, we focus on the impact of stand your ground, right to carry and background checks laws and how they impact changes in homicide rates. Using a unique data set, we created a change point model and used regression models to show that changes to handgun laws do in fact impact homicide rates in many state

    Author Deborah Heffernan of Bridgton describes how secret plans to have a Queen Anne bonnet-top high boy built for her husband Jack Heffernan turned into a community affair, while yet remaining a secret. The actual design and construction of the high boy fell on Bob Dunning, with the help cabinetmaker Greg Marston. Others involved on the project included Mary and Don Johnson and their sons Tom and Eric. With descriptive details of elements included in the highboy

    Beyond audacity: Supporting sonic futures through the digital audio workstation

    No full text
    The article suggests that the non-destructive editing features of the Digital Audio Workstation (DAW) can be useful for communication centers and for the support of multimodal assignments because they can promote greater attention to sound. The turn to the DAW is situated in a tradition of embracing sonic technologies for pedagogical purposes through analysis of the history of discussions of microphonic and recording technology in the Quarterly Journal of Speech. The author surveys available DAW software and cites experience using it at one center

    The problem of the Hungarian borders and minorities in British foreign political thought, 1938-41

    No full text
    This thesis analyses the British official attitudes and the gradual change of British policy towards Hungary and Hungarian revisionism in the period from the Anschluss in March 1938 to December 1941, when the British government declared war on Hungary. The primary focus of this thesis lies in the impact of Hungary`s territorial claims on British policy towards Hungary and Central Europe and upon the criteria Britain judged the territorial gains of Hungary between 1938 and 1941. This work is the result of the author`s research in British, American and Hungarian archives, along with his reflection on numerous documentary editions, diaries, memoirs and secondary sources. It aims to deepen our knowledge of Anglo-Hungarian relationship, British Central European policy and the British view of regional territorial disputes. At the same time, it is keen to dispel the myths and stereotypes of the British and Hungarian historiography, which have so far viewed Hungary as an unimportant factor in British Central European strategy

    Dopamine restores reward prediction errors in old age

    Senescence affects the ability to utilize information about the likelihood of rewards for optimal decision-making. Using functional magnetic resonance imaging in humans, we found that healthy older adults had an abnormal signature of expected value, resulting in an incomplete reward prediction error (RPE) signal in the nucleus accumbens, a brain region that receives rich input projections from substantia nigra/ventral tegmental area (SN/VTA) dopaminergic neurons. Structural connectivity between SN/VTA and striatum, measured by diffusion tensor imaging, was tightly coupled to inter-individual differences in the expression of this expected reward value signal. The dopamine precursor levodopa (L-DOPA) increased the task-based learning rate and task performance in some older adults to the level of young adults. This drug effect was linked to restoration of a canonical neural RPE. Our results identify a neurochemical signature underlying abnormal reward processing in older adults and indicate that this can be modulated by L-DOPA

    Discretised Procedural Timber: An Investigation into robotic manufacturing & assembly for residential timber construction

    No full text
    This project seeks to investigate the multiple materialisation approaches of timber as a construction material for a residential/mixed use building sited in Berlin, Germany. Seeing as there is a major housing crisis Europe wide with the added concern of the growing environmental concern, this proposal aims to be the embodiment of applied research in timber construction, combining both techniques of mass customisation as well as standardisation. The ethos is that while some aspects of the project must utilise innovative construction technologies such as robotics, other facets still rely on standardised components. This philosophy is rooted in that a complete overnight transition from one industrial construction methodology (standardisation) to a new era of mass customisation is too abrupt for the construction industry. Therefore a hybrid adaptation of both system within project, would be the methodology to tackle this issue and further advocate for how innovation in the construction industry can be hybridised rather than completely revamped. Furthermore, this research and development endeavour tackles the topic of housing which intuitively is a logical testing ground for this proof of concept. The two main avenues of research in this project are the following: 1: Discretised timber joinery system (mass standardisation)2: Large timber compression shells (mass customisation)The goal being to utilise both methodologies only where appropriate. For example, areas of the building that are under large amounts of compression forces such as the timber shell anchors are fabricated though a method of robotic subtraction given a wooden bounding box. Other areas such as partition walls, flooring, and facade, utilise a more standard approach combining material strategies such as CLT, particle board and simple timber structural beams/girders that aggregate in an additive fashion.Conclusively this project attempts to showcase the multiple use of timber as a construction material and how different treatments of this diverse and living material can encompass larger portions of the construction of a building then we originally thought. The idea being to reduce the amount of materials being used in a building as much as possible and advocating for timber being the construction material of the future especially when integrated with robotic building operations.Robotic Building | HyperbodyArchitecture, Urbanism and Building Sciences | Robotic Buildin
