    Expanding Our Boundaries With Information Literacy

    Full text link
    Years ago I had a calling to a special ministry, but I didn\u27t think of it that way. At the time it seemed more a desire, whereas callings had to do with going into overseas missionary work or into a full time Christian ministry. My calling came a few years after the birth of my son when I was working with a capital campaign for the United Presbyterian Church. The $50 million dollar campaign was coming to an end, and that meant my job would soon be over. Although I was offered a higher-level position with the Foundation - one I might add, which had only been held by men up until then, I kept thinking back to a black and white photograph and knew I had to become a librarian

    The Witness of the Worshiping Community

    (Excerpt) Christ is risen! Alleluia! CR: He is risen indeed! Alleluia!) What more does the church have to do than to proclaim this? What else must the church witness to than the resurrection of the crucified One, who is present in its midst through the preaching of the gospel and the administration of the sacraments? Oh, yes, we have to spin out the meaning of the cross and resurrection of Christ; we have to celebrate it worthily and compellingly in our public assemblies; we have to reorder our lives In conformity with its implications, turning away from the way of the world and toward the new life under Christ\u27s reign; we have to invite others to reorder their lives according to this new reality for the world; and we want to invite them to join us in a community of proclamation and celebration

    The Constitution on the Sacred Liturgy and Lutheran Book of Worship: What Was Renewed?

    Get PDF
    (Excerpt) Missing first four pages of the 1970s there were those who objected to the idea of liturgy as action because they thought it placed an undue emphasis on human activity instead of on God\u27s work through the means of grace.4 Obviously, liturgy is a work performed by a person or a community, so human action is unavoidable. It is a human act to read scriptures, preach sermons, baptize, or proclaim the words of institution, even though we confess that the Holy Spirit works through these means of grace to create or awaken faith. One may also say that liturgy, like all the activities of the church, is inspired or engendered by the Holy Spirit. For this reason the chief service has been called \u27\u27the divine liturgy (e.g. the Divine Liturgy of St. John Chrysostom)

    Insights into enzymatic halogenation from computational studies

    Get PDF
    The halogenases are a group of enzymes that have only come to the fore over the last 10 years thanks to the discovery and characterization of several novel representatives. They have revealed the fascinating variety of distinct chemical mechanisms that nature utilizes to activate halogens and introduce them into organic substrates. Computational studies using a range of approaches have already elucidated many details of the mechanisms of these enzymes, often in synergistic combination with experiment. This Review summarizes the main insights gained from these studies. It also seeks to identify open questions that are amenable to computational investigations. The studies discussed herein serve to illustrate some of the limitations of the current computational approaches and the challenges encountered in computational mechanistic enzymology

    You May Believe You Are a Bayesian But You Are Probably Wrong

    An elementary sketch of some issues in statistical inference and in particular of the central role of likelihood is given. This is followed by brief outlines of what George Barnard considered were the four great systems of statistical inferences. These can be thought of terms of the four combinations of two factors at two levels. The first is fundamental purpose (decision or inference) and the second probability argument (direct or inverse). Of these four systems the 'fully Bayesiani approach of decision- making using inverse probability particularly associated with the Ramsay, De Finetti, Savage and Lindley has some claims to be the most impressive. It is claimed, however, and illustrated by example, that this approach seems to be impossible to follow. It is speculated that there may be some advantage to the practising statistician to follow George Barnardis advice of being familiar with all four systems.philosophy of statistics, decision theory, likelihood, subjective probability, Bayesianism, Bayes theorem, Fisher, Neyman and Pearson, Jeffreys

    Formation and structure of the ferryl [Fe=O] in-termediate in the non-haem iron halogenase SyrB2: classical and QM/MM modelling agree

    To rationalise mechanistically the intriguing regio- and chemoselectivity patterns for different substrates of the non-haem iron/2-oxoglutarate dependent halogenase SyrB2, it is crucial to elucidate the structure of the pivotal [FeIV[double bond, length as m-dash]O] intermediate. We have approached the problem by a combination of classical and QM/MM modelling. We present complete atomistic models of SyrB2 in complex with its native substrate L-threonine as well as L-α-amino butyric acid and L-norvaline (all conjugated to the pantetheine tether), constructed by molecular docking and extensive MD simulations. We evaluate five isomers of the [Fe[double bond, length as m-dash]O] intermediate in these simulations, with a view to identifying likely structures based on a simple “reaction distance” measure. Starting from models of the resting state, we then use QM/MM calculations to investigate the formation of the [Fe[double bond, length as m-dash]O] species for all three substrates, identifying the intermediates along the O2 activation/decarboxylation pathway on the S = 1, 2, and 3 potential-energy surfaces. We find that, despite differences in the detailed course of the reaction, essentially all pathways produce the same [Fe[double bond, length as m-dash]O] structure, in which the oxido is directed away from the substrate

    Toward a Unified Performance and Power Consumption NAND Flash Memory Model of Embedded and Solid State Secondary Storage Systems

    Full text link
    This paper presents a set of models dedicated to describe a flash storage subsystem structure, functions, performance and power consumption behaviors. These models cover a large range of today's NAND flash memory applications. They are designed to be implemented in simulation tools allowing to estimate and compare performance and power consumption of I/O requests on flash memory based storage systems. Such tools can also help in designing and validating new flash storage systems and management mechanisms. This work is integrated in a global project aiming to build a framework simulating complex flash storage hierarchies for performance and power consumption analysis. This tool will be highly configurable and modular with various levels of usage complexity according to the required aim: from a software user point of view for simulating storage systems, to a developer point of view for designing, testing and validating new flash storage management systems
