    The Bank of England and the genesis of modern management

    In 1965 Sidney Pollard published The Genesis of Modern Management, an extended discussion of the problems, during Britain’s initial period of industrialisation, of the ‘internal management’ of the firm. But, in his focus on industry, Pollard ignored one of the largest, most significant and most innovative of the enterprises of the late-eighteenth- and early-nineteenth centuries: The Bank of England. This paper focuses on the Bank as a site of precocious managerial development. It first establishes that the Bank, by the latter part of the eighteenth century, encompassed the complexities of a large-scale industrial enterprise. It employed a workforce of several hundred. Its workers operated in specialised and coordinated capacities. Its managerial hierarchy was diffuse and dependent on employed men, rather than the elected directorate. The Bank, therefore, warrants comparison with the types of enterprises identified by Pollard. Focusing on the 1780s, the paper then explores the Bank’s organisational and management structure against Pollard’s four aspects of management: ‘the creation and training of a class of managers; ‘the recruitment, training, disciplining and acculturation of labour’; the use of ‘accountancy, and other information …in the rational determination of their decisions’ and finally the question of whether there emerged a ‘theory and practice of “management”’. It will demonstrate that, although not always applied effectively, the Bank’s senior men did show managerial innovation and skill in training and organising the workforce and were able to make informed decisions which had the potential to improve some of the Bank’s processes

    ‘You do manage it so well that I cannot do better’: the working life of Elizabeth Jeake of Rye (1667-1736)

    This is an Accepted Manuscript of an article published by Taylor & Francis in Women's History Review on 27 March 2018, available online at: https://doi.org/10.1080/09612025.2018.145556. Under embargo until 27 September 2019.This article contributes to the debate around early modern women’s work. It concerns not waged labour but rather the unpaid contributions made by women to both home and the business undertaken by their husband. It focuses on Elizabeth Jeake, the wife of Samuel Jeake, a merchant from the Sussex port of Rye. Through the letters exchanged between the family, it explores Elizabeth’s skilled work in support of her husband. This included giving instructions to contractors, gathering and disseminating business and investment information, negotiations with Samuel’s business partners and acquaintances, managing property and tenants, negotiating credit relationships and purchasing and selling commodities.Peer reviewedFinal Accepted Versio

    Identification of Demand through Statistical Distribution Modeling for Improved Demand Forecasting

    Full text link
    Demand functions for goods are generally cyclical in nature with characteristics such as trend or stochasticity. Most existing demand forecasting techniques in literature are designed to manage and forecast this type of demand functions. However, if the demand function is lumpy in nature, then the general demand forecasting techniques may fail given the unusual characteristics of the function. Proper identification of the underlying demand function and using the most appropriate forecasting technique becomes critical. In this paper, we will attempt to explore the key characteristics of the different types of demand function and relate them to known statistical distributions. By fitting statistical distributions to actual past demand data, we are then able to identify the correct demand functions, so that the the most appropriate forecasting technique can be applied to obtain improved forecasting results. We applied the methodology to a real case study to show the reduction in forecasting errors obtained

    Optically actuated two position mechanical mover

    Get PDF
    An optically actuated mechanical mover adapted to be moved from an ambient position to an active position, is disclosed. The mechanical mover essentially comprises a piston/cylinder arrangement including a piston that is contained within an internal cylindrical chamber of a housing. The cylindrical chamber is configured to permit the piston to be moved for the length of the chamber as a work stroke. A lock pin extending through the piston, and diametrically opposed walls of the chamber housing, retain the piston in the ambient position at one end of the chamber. An actuator for producing a pressure or shock wave that drives the piston is positioned at the end of the chamber corresponding to the piston ambient position

    The dust content of damped Lyman-alpha systems in the Sloan Digital Sky Survey

    Full text link
    The dust-content of damped Lyman-alpha systems (DLAs) is an important observable for understanding their origin and the neutral gas reservoirs of galaxies. While the average colour-excess of DLAs, E(B-V), is known to be <15 milli-magnitudes (mmag), both detections and non-detections with ~2 mmag precision have been reported. Here we find 3.2-sigma statistical evidence for DLA dust-reddening of 774 Sloan Digital Sky Survey (SDSS) quasars by comparing their fitted spectral slopes to those of ~7000 control quasars. The corresponding E(B-V) is 3.0 +/- 1.0 mmag, assuming a Small Magellanic Cloud (SMC) dust extinction law, and it correlates strongly (3.5-sigma) with the metal content, characterised by the SiII1526 absorption-line equivalent width, providing additional confidence that the detection is due to dust in the DLAs. Evolution of E(B-V) over the redshift range 2.1 < z < 4.0 is limited to <2.5 mmag per unit redshift (1-sigma), consistent with the known, mild DLA metallicity evolution. There is also no apparent relationship with neutral hydrogen column density, N(HI), though the data are consistent with a mean E(B-V)/N(HI) = (3.5 +/- 1.0) x 10^{-24} mag cm^2, approximately the ratio expected from the SMC scaled to the lower metallicities typical of DLAs. We implement the SDSS selection algorithm in a portable code to assess the potential for systematic, redshift-dependent biases stemming from its magnitude and colour-selection criteria. The effect on the mean E(B-V) is negligible (<5 per cent) over the entire redshift range of interest. Given the broad potential usefulness of this implementation, we make it publicly available.Comment: Accepted to MNRAS. 18 pages, 17 figures, 5 tables.

    Embracing Localization Inaccuracy: A Case Study

    Get PDF
    In recent years, indoor localization has become a hot research topic with some sophisticated solutions reaching accuracy on the order of ten centimeters. While certain classes of applications can justify the corresponding costs that come with these solutions, a wealth of applications have requirements that can be met at much lower cost by accepting lower accuracy. This paper explores one specific application for monitoring patients in a nursing home, showing that sufficient accuracy can be achieved with a carefully designed deployment of low-cost wireless sensor network nodes in combination with a simple RSSI-based localization technique. Notably our solution uses a single radio sample per period, a number that is much lower than similar approaches. This greatly eases the power burden of the nodes, resulting in a significant lifetime increase. This paper evaluates a concrete deployment from summer 2012 composed of fixed anchor motes throughout one floor of a nursing home and mobile units carried by patients. We show how two localization algorithms perform and demonstrate a clear improvement by following a set of simple guidelines to tune the anchor node placement. We show both quantitatively and qualitatively that the results meet the functional and non-functional system requirements

    Broad-Band Soft X-ray Polarimetry

    Full text link
    We developed an instrument design capable of measuring linear X-ray polarization over a broad-band using conventional spectroscopic optics. A set of multilayer-coated flats reflects the dispersed X-rays to the instrument detectors. The intensity variation with position angle is measured to determine three Stokes parameters: I, Q, and U -- all as a function of energy. By laterally grading the multilayer optics and matching the dispersion of the gratings, one may take advantage of high multilayer reflectivities and achieve modulation factors > 50% over the entire 0.2 to 0.8 keV band. This instrument could be used in a small orbiting mission or scaled up for the International X-ray Observatory. Laboratory work has begun that would demonstrate the capabilities of key components.Comment: 6 pages, 3 figures (2 color); to appear in proceedings of "The Coming of Age of X-ray Polarimetry
