    Intellectual Humility

    We critique two popular philosophical definitions of intellectual humility: the “low concern for status” and the “limitations-owning.” accounts. Based upon our analysis, we offer an alternative working definition of intellectual humility: the virtue of accurately tracking what one could non-culpably take to be the positive epistemic status of one’s own beliefs. We regard this view of intellectual humility both as a virtuous mean between intellectual arrogance and diffidence and as having advantages over other recent conceptions of intellectual humility. After defending this view, we sketch remaining questions and issues that may bear upon the psychological treatment of intellectual humility such as whether evidence will help determine how this construct relates to general social humility on the one hand, and intellectual traits such as open-mindedness, curiosity, and honesty on the other

    Invariant optimal control on the three-dimensional semi-Euclidean group: control affine and quadratic Hamilton-Poisson systems

    Get PDF
    In this thesis we consider invariant control systems and Hamilton-Poisson systems on the three dimensional semi-Euclidean group SE(1,1). We first classify the left-invariant control affine systems (under detached feedback equivalence). We provide a complete list of normal forms, as well as classifying conditions. As a corollary to this classification, we derive controllability criteria for control affine systems on SE(1,1). Secondly, we consider quadratic Hamilton-Poisson systems on the (minus) Lie-Poisson space se(1,1)*. These systems are classified up to an affine isomorphism. Six normal forms are identified for the homogeneous case, whereas sixteen representatives (including several infinite families) are obtained for the inhomogeneous systems. Thereafter we consider the stability and integration of the normal forms obtained. For all homogeneous systems, and a subclass of inhomogeneous systems, we perform a complete stability analysis and derive explicit expressions for all integral curves. (The extremal controls of a large class of optimal control problems on SE(1,1) are linearly related to these integral curves.) Lastly, we discuss the Riemannian and sub-Riemannian problems. The (left-invariant) Riemannian and sub-Riemannian structures on SE(1,1) are classified, up to isometric group automorphisms and scaling. Explicit expressions for the geodesics of the normalised structures are found

    The impact of Scotland‟s economy on the environment : a note on input-output and ecological footprint analysis

    Get PDF
    Several recent papers examining the impact of the Scottish and Jersey economy on the environment have criticised the Ecological Footprint (EF) method and have suggested the use of input-output (IO) analysis instead (McGregor et al., 2004a; McGregor et al., 2004b; Ferguson et al., 2004; Allan et al., 2004). It is argued that “IO can be used to provide a coherent and practical alternative method to the Ecological Footprint of locating the responsibility and source of resource use and waste/pollution” (Allan et al., 2004) and several aspects of the EF methodology are criticised specifically. In this paper we reply to these critiques and discuss the scope and limitations of both the NCLAS as well as the Ecological Footprint. We argue that EF and IO are complementary methods that can be combined in a meaningful way. We suggest a way forward that helps to improve the scientific understanding of key sustainable development issues

    The Context of Suffering

    Get PDF
    While the evidential problem of evil has been enormously influential within the contemporary philosophical literature—William Rowe’s 1979 formulation in “The Problem of Evil and Some Varieties of Atheism” being the most seminal—no academic research has explored what cognitive mechanisms might underwrite the appearance of pointlessness in target examples of suffering. In this exploratory paper, we show that the perception of pointlessness in the target examples of suffering that underwrite Rowe’s seminal formulation of the problem of evil is contingent on the absence of broader context. In other words, we show that when such suffering is presented alongside broader contextual information, the appearance of pointlessness, on average, significantly diminishes.  In §1 we briefly elucidate Rowe’s formulation of the problem of evil and the thought experiment that motivates a key premise. In §2 and §3 respectively, we briefly explain our hypothesis regarding Rowe’s case and our methods for testing these hypotheses. In §4, we elucidate our results, and in §5 we explore some of the philosophical implications of our findings and gesture towards some areas for future research. Finally, in §6, we briefly connect our research to some of the established philosophical literature on suffering and narrative before concluding

    The responsiveness of government revenue to marginal tax rates

    Get PDF
    Ce document utilise des données fiscales et démographiques pour calculer les changements dans les recettes du gouvernement engendrés par les ajustements dans le taux marginal d'imposition, et cela en mettant l’accent sur la fourchette d'imposition la plus élevée. La portée de l’étude est une sélection de pays de l’O.C.D.E. Une analyse des changement de comportement des contribuables et des différentes alternatives dont le gouvernement dispose en termes de politique fiscale en suivaient. En fin, les possibles faiblesses dans des techniques de référence sont examinées en détail. This thesis uses demographic and income tax data to calculate changes in government revenue following adjustments to marginal tax rates, with a focus on the highest tax bracket. The study’s scope is a variety of O.E.C.D. countries. An analysis of behavioral responses of tax payers and the options available to government in terms of taxation policy follows. Past measurement techniques are also scrutinized

    Influence of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica

    Archaea are the least understood members of the microbial community in Antarctic mineral soils. Although their occurrence in Antarctic coastal soils has been previously documented, little is known about their distribution in soils across the McMurdo Dry Valleys, Victoria Land. In this study, terminal-restriction fragment length polymorphism (t-RFLP) analysis and 454 pyrosequencing were coupled with a detailed analysis of soil physicochemical properties to characterize archaeal diversity and identify environmental factors that might shape and maintain archaeal communities in soils of the three southern most McMurdo Dry Valleys (Garwood, Marshall, and Miers Valley). Archaea were successfully detected in all inland and coastal mineral soils tested, revealing a low overall richness (mean of six operational taxonomic units [OTUs] per sample site). However, OTU richness was higher in some soils and this higher richness was positively correlated with soil water content, indicating water as a main driver of archaeal community richness. In total, 18 archaeal OTUs were detected, predominately Thaumarchaeota affiliated with Marine Group 1.1b (> 80% of all archaeal sequences recovered). Less abundant OTUs (2% of all archaeal sequences) were loosely related to members of the phylum Euryarchaeota. This is the first comprehensive study showing a widespread presence and distribution of Archaea in inland Antarctic soils

    Devon Island Programs, 1968

    Get PDF
    Four field parties, studying glaciology, botany and ornithology, used the Arctic Institute's facilities on Devon Island during the summer of 1968. The botanical and ornithological studies were carried out from the Base Camp near Cape Sparbo, while the glaciological work was pursued from field camps on the ice cap and the Sverdrup Glacier. ..
