Critical properties of the four-state commutative random permutation glassy Potts model in three and four dimensions
No full textWe investigate the critical properties of the four-state commutative random permutation glassy Potts model in three and four dimensions by means of Monte Carlo simulations and a finite-size scaling analysis. By using a field programmable gate array, we have been able to thermalize a large number of samples of systems with large volume. This has allowed us to observe a spin-glass ordered phase in d=4 and to study the critical properties of the transition. In d=3, our results are consistent with the presence of a Kosterlitz-Thouless transition, but also with different scenarios: transient effects due to a value of the lower critical dimension slightly below 3 could be very important
"Feed my lambs" : the spiritual direction ministry of Calvinistic British Baptist Anne Dutton during the early years of the evangelical revival.
No full textThis dissertation contends that Anne Dutton (1692-1765) contributed a transatlantic ministry of spiritual direction to the Evangelical Revival in the early 1740s. The first chapter provides a historiographical review of Dutton's reception in the
eighteenth and nineteenth centuries and the state of contemporary scholarship of Dutton. The chapter concludes with a historical reflection on spiritual direction, situating Dutton in the tradition of Protestant epistolary spiritual counseling and the long history of women spiritual directors. Chapter two provides an analysis of Dutton's early life in light of the autobiographies of Anne and her husband, Benjamin Dutton. The third chapter demonstrates that Anne Dutton's early literary productions were grounded in the spiritual formation she received in High Calvinistic congregations that encouraged experiential biblicism and Puritan spirituality. Of particular influence upon Dutton was the Puritan Thomas Goodwin with his interpretations of the "ages of Christianity" and the "sealing of the Spirit." Chapter four reconstructs Dutton's early correspondence with Howell Harris, John Wesley, and George Whitefield. The chapter demonstrates that Dutton's Calvinistic spiritual writings were attractive to Harris and Whitefield (who in turn expanded her social-spiritual direction network) and suggests Dutton's direction to these men is best defined as spiritual confirmation. The fifth chapter examines Dutton's presence in the first evangelical magazine, the London Weekly Papers, as the anonymous "Friend in the Country." Published by Dutton's correspondent John Lewis, the magazine included several of Dutton's spiritual pieces and advertised a number of her published works. Dutton's contributions to this publication demonstrate her usefulness to Calvinistic Methodism and the extensiveness of her influence, albeit anonymous, on readers in England, Scotland, and America. Chapter six analyzes Dutton's Letter-Books published in the 1740s. These volumes exhibit her transatlantic influence and the defining elements of her personal spiritual direction. The Letter-Books reveal Dutton's correspondents relating to her as a spiritual director: one who was holy, knowledgeable, compassionate, wise, and discerning. The chapter concludes suggesting Dutton's Letter-Books reflect the expansion and contraction of Dutton's influence in the Evangelical Revival. A final chapter summarizes the contributions of this project to the study of Anne Dutton's life, spirituality, and ministry.by Michael D. Sciretti, Jr.Ph.D
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
