Brazen as Falstaff, Devious as Iago: Sir Ralph Lane's Approach to Holding Office in Ireland and Virginia

AbstractMuch has been made of the ideological connection between the mental world of servitors in Elizabethan Ireland and the origins of early English colonial endeavor in North America. In this vein, the case of Sir Ralph Lane, the first governor of the Roanoke colony and, later, muster-master general of Ireland, would seem to present a historiographically promising test case, one that might not only link Ireland and the Roanoke Colony but also could show, following recent suggestions, how attitudinal, behavioral, and aspirational commonalities existed between early modern English military culture and the ethos of early English colonial endeavor. Lane's record on both sides of the Atlantic, however, rather than painting a picture of the applicability of martial virtue and military discipline at times of crisis, demonstrates instead the stark reality of the impulsive and appetitive culture of the garrison in the Elizabethan period and its corrosive effects. Lane's remarkable capacity for corruption, willful mismanagement, and wily self-defense in an Irish context in fact amplifies and complements troubling tendencies that scholars have recently detected in Lane's famous discourse of his government in what was commonly termed Virginia printed in Hakluyt's Principal Navigations. Lane can indeed serve as an emblem of common features shared by Elizabethan Englishmen drawn to office in Ireland and Elizabethan/Jacobean Englishmen drawn to settle in Virginia, but largely because of his mendacity, venality, and irresponsibility.

Cut-off grade optimisation to maximise the net present value using whittle 4X

Cut-off grade optimisation is necessary for operational decision making in the many different circumstances affecting mine operations. The cut-off grades are supposed to reflect particular circumstances of specific mines in order to achieve the maximum economic return over the life of the mine. The relationship between cut-off grade and NPV provides a means by which cut-off grades are optimised. Using Lane's approach, the economics involved in each stage are identified independently and integrated to provide an optimum cut-off grade. A block model from a hypothetical gold mine is used to illustrate how Whittle 4X applies Lane's approach to generate an optimal cut-off grade policy for the mine. The cut-off grade in this project slightly changes along the mine life. Higher grade ore is mined in the early years (years 2 and 4) while the lower grade ore is mined later.
