    Enantioselective Synthesis of 5-epi-Citreoviral Using Ruthenium-Catalyzed Asymmetric Ring-Closing Metathesis

    Get PDF
    Chiral ruthenium olefin metathesis catalysts can perform asymmetric ring-closing reactions in ≥90% ee with low catalyst loadings. To illustrate the practicality of these reactions and the products they form, an enantioselective total synthesis of 5-epi-citreoviral was completed by using an asymmetric ring-closing olefin metathesis reaction as a key step early in the synthesis. All of the stereocenters in the final compound were set by using the chiral center generated by asymmetric olefin metathesis

    Leading the Assembly Is Pastoral

    Get PDF
    (Excerpt) I should begin, I think, by explaining a bit about what I mean by pastoral when we speak about leading the assembly. We got a phone call once at the National Association of Pastoral Musicians from a scholar who was researching the folk music of Greek shepherds, and he thought that we might be of some help, since we are also interested in things pastoral. That isn\u27t the pastoral that I have in mind! Instead, my vision of pastoral leadership is rooted in the story at the end of John\u27s gospel where Jesus asks Peter three times, Simon, son of Jolm, do you love me? Each time, when Peter answers in the affirmative, Jesus responds, Then feed my lambs .... Tend my sheep .... Feed my sheep (John 21:15-17)

    On the Travesty of the Tragedy of the Commons: Hardin's Nontrivial Error

    Get PDF
    Garrett Hardin’s "Tragedy of the Commons" remains one of the most frequently cited works across the spectrum of science — indeed, a visit to the website of the influential journal which published this paper in 1968 reveals that this revolutionary communique remains amongst its ‘top articles’. But Hardin's enduring, influential theoretical development presents a serious problem: it is not a single theory, but rather four major theories in a stormy sea of ill-conceived and untenable auxiliary conjecture. Moreover, the solid core of Hardin's central thesis was simply a restatement of a previously published theory, the promethean vision of William Forster Lloyd.Tragedy of the Commons; William Forster Lloyd; Garrett Hardin; Scientific Method;

    On the Problem of Dependent People: hyperbolic discounting in Atlantic Canadian island jurisdictions

    Prince Edward Island's Economics, Statistics and Federal Fiscal Relations Division's 33rd Annual Statistical Review reports the total value of 2006 fish landings was CAD $166.6 MM. This paper discloses a preliminary finding that the actual total value of fish landings for 2006 was approximately CAD 416.5 MM. Furthermore, this discourse submits that this entrenched systemic error has been consistently generated for all 33 years that the Annual Statistical Review has been published. Moreover, this systemic error creates a ripple-effect and promotes bias through all relative natural resource valuations. This significant conjecture is presented within an institutional context which serves as the foundation for this error generation, including other errors associated with The Problem of Induction and The Tragedy of the Commons. Within this broad context, this paper focuses upon deficient resource valuation methods, especially as they relate to dependency and valuation errors. Our analysis contrasts the failure of fishery management amongst dependent Canadian islanders,and the relative success of fishery management amongst independent Icelandic islanders. The possibilities that independent people enjoy higher levels of rationality, efficiency, happiness, economic sustainability, Darwinian fitness, resource holding power, and, are thus, ceteris paribus, less likely to commit errors associated with The Problem of Induction are taken into consideration. Likewise, consideration is given to the notion that dependent people are more likely to exhibit irrational behaviour, develop deeper dependencies, and to contribute to a wide array of maladaptive behaviours, such as those which exacerbate The Tragedy of the Commons.tragedy of the commons; insularity; problem of induction; methodology; sub-national island jurisdiction; prince edward island; cancer; bravo; potato production; Chlorothalonil Carcinogenicity; prince edward island development plan; confederation bridge; prince edward island tourism

    On the Truly Noncooperative Game of Island Life: Introducing a Unified Theory of Value & Evolutionarily Stable Island Economic Development Strategy

    Get PDF
    This discourse offers a solution to The Problem of Sustainable Economic Development on islands. This hypothesis offers a foundational, sub-game solution to The Island Survival Game, a counterintuitive, dominant economic development strategy for ‘islands’ (and relatively insular states). This discourse also tables conceptual building blocks, prerequisite analytical tools, and a guiding principle for The Earth Island Survival Game, a bounded delay supergame which models The Problem of Sustainable Economic Development at the global level. We begin our exploration with an introduction to The Principle of Relative Insularity, a postulate which informs ESS for ‘island’ and ‘continental’ players alike. Next, we model ‘island’ economic development with two bio-geo-politico-economic models and respective strategies: The Mustique Co. Development Plan, and The Prince Edward Island Federal-Provincial Program for Social and Economic Advancement. These diametrically opposed strategies offer an extraordinary comparative study. One island serves as a highly descriptive model for The Problem of Sustainable Economic Development; the other model informs ESS. The Island Survival Game serves as a remarkable learning tool, offering lessons which promote Darwinian fitness, resource holding power, self-sufficiency, and cooperative behaviour, by illuminating the illusive path toward sustainable economic development.Non-cooperative games, evolutionary game theory, relative insularity, islands, tragedy of the commons, sustainable economic development, resource holding power, evolutionarily stable strategy, long distance dispersal
