    Inspired by work published in our group utilizing macrocyclic nitrogen based pyridinophane (N4) and triazacyclononane (tacn) ligands for the isolation and study of high-valent nickel and palladium compounds, chiral variants of these ligands were synthesized in attempts to isolate high-valent organometallic nickel complexes that could play a role in enantioselective crosscoupling reactions. Utilizing readily available chiral pool primary amines, the synthesis of N4 type ligands can be amended to install chirality on the tertiary amines of the ligand, which commonly bind through dative interactions with the metal center in high-valent oxidation states. Furthermore, the synthesis can be expanded to N3 type pyridinophane compounds like N3CBr type ligands, allowing for on-ligand reactivity studies to be conducted. With these ligands in hand, a secondary organometallic nucleophile was synthesized which could allow for the synthesis of organometallic nickel complexes. The reactivity of these complexes was then examined, with hopes that insight into the role of high-valent complexes and the method for stereoinduction in enantioselective cross-coupling reactions could then be better understood. Furthermore, a synthetic route to novel chiral variants of triazacyclononane ligands was developed based on a ‘crab-like’ synthesis published by the Scarborough group in 2018. This synthesis relies on commercially available alpha-hydroxy acids, and the substituents on the ligand can be varied in a multitude of locations. This ligand synthesis allows for installation of chirality on the methylene backbone of the ligand, which will hopefully result in good chiral projection into the open binding sites of the metal complex. Further efforts to develop reactivity with this system are currently underway.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2023-08-01The student, Neil Heberer, accepted the attached license on 2021-07-08 at 12:27.The student, Neil Heberer, submitted this Thesis for approval on 2021-07-08 at 12:30.This Thesis was approved for publication on 2021-07-16 at 15:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #16802 on 2022-01-12 at 12:54:00Made available in DSpace on 2022-01-12T22:35:06Z (GMT).

    No full text
    The future of the religion lies with young people, whose lives are now riddled with uncertainty due to the COVID-19 pandemic. In this presentation, Dr. Josh Packard will draw from Springtide Research Institute’s annual State of Religion & Young People study to explain the spiritual lives of Gen Z and how we need to re-think everything when it comes to how we engage the most diverse generation in history. Rev. Neil Ellingson will moderate the Q & A period. Dr. Josh Packard is Executive Director of Springtide Research Institute, which maintains the largest dataset on young people and their spirituality in the U.S. Josh has a doctorate in sociology from Vanderbilt and he’s the author of several books including Meaning Making: 8 Values that Drive America’s Newest Generations and Church Refugees: Why People are Done with Church but Not their Faith. Josh is a sought-after speaker and author and has been featured in the Wall Street Journal, Washington Post, CBS, USA Today, and more. Pastor Neil Ellingson is Associate Chaplain in Campus Ministry at the University of St. Thomas. An ordained minister in the United Church of Christ, Ellingson holds a B.A. from Harvard University and a Master of Divinity degree from the University of Chicago Divinity School. He founded Root and Branch, a “dinner church” in Chicago, which continues to flourish. Sponsored and organized by the Jay Phillips Center for Interreligious Studies in collaboration with the Department of Theology, Campus Ministry, Student Diversity & Inclusion Services, and the Office of Human Resources at the University of St. Thomas (Minnesota, USA) with generous support from the Jay and Rose Phillips Family Foundation of Minnesota

    Author identification: national and disciplinary approaches

    No full text
    Author identication can be provided by authors themselves, or be intermediaries. Authors can be identified ex-post, within sets of bibliographic data, or ex-ante, when publication data is composed. Leo Waaijers introduces the digital author identifier, as working in the DARE project. It is based on old library technology, yet compliant with the forthcoming ISO standard on party identification ISPI. Thomas Krichel introduces the ACIS project (http://acis.openlib.org) and its first implementation in the RePEc author service (http://authors.repec.org). This is a low-cost approach. It relies on authors themselves to register. A central registration is a pure ex-post operation. However, it can be combined with an archival operation to permit additional ex-ante registered author data

    Reading the Nibelungenlied.

    No full text
    Neil Thomas's Reading the Nibelungenlied attempts to access the mainsprings of what nineteenth- and twentieth-century German writers such as Wagner, Volker Braun and Heiner Mueller have seen as the master narrative of the German tradition. In its story of jealousy, factionalism and self-destruction (which privatises various world-historical events around the time of the Migrations and the floruit of the historical Attila the Hun), Thomas discovers a mirror of certain aspects of the modern German cultural condition. In a study which depends on both a close reading of the medieval text and on comparison with Scandinavian analogues such as the Saga of the Volsungs and other Old High German and Latin cognates, the author finds a work whose cumulative effects are as compelling as Shakespearian tragedy

    Apocalypticisim in the fiction of William S. Burroughs, J.G. Ballard, and Thomas Pynchon.

    No full text
    Apocalypse should not be thought of as merely a synonym for chaos or disaster or cataclysmic upheaval; more properly we should think of disclosure, unveiling and revelation. The exact status of literary apocalyptic is the subject of some debate, and in an attempt to help clarify matters an introductory historical survey examines both the formal characteristics of apocalypse and the various critical positions taken in regard to the genre's social influence. Texts considered in the chapter include the Revelation of John and Thomas Pynchon's short story Entropy (1959); theoretical works by Frank Kermode, John Barth, and Jean Baudrillard (amongst others) are also discussed. Chapter One traces the development of William S. Burroughs's apocalyptic sensibility through readings of his correspondence with Allen Ginsberg and the novel The Naked Lunch (1959); the latter's apocalyptic title referring to the "frozen moment when everyone sees what is on the end of every fork". Chapter Two considers Burroughs's experiments with the "cut-ups" and their application in a number of texts, most notably Nova Express (1964). Chapter Three is concerned with Burroughs's work in the 1970s and 80s, and specifically his concept of Here to Go, a theory of mutability presented as a transcendental antidote to the threat of nuclear annihilation (the author's alleged misogyny and the views of radical US feminists are also taken into account). Chapters Four and Five explore the apocalyptic fiction of J. G. Ballard; topics covered include Ballard's concept of inner space, his debt to Surrealism, and the coded landscapes of his more experimental texts; in particular the "condensed novels" which comprise The Atrocity Exhibition (1970). A concluding chapter returns to the work of Thomas Pynchon, offering a reading of Gravity's Rainbow (1973) which allows us to consider his treatment of such related themes as Paranoia, Holocaust, Apocalypse, and finally, Counterforce

    "Coordinating Regional Policy in the EU"

    No full text
    [From the Introduction]. EU regional policy is an instrument to promote development in economically weaker areas of Europe as well as to facilitate integration and ensure the success of the single market (European Commission, 2003). The territorial nature of EU regional policy demands complex coordination among various levels of government as well as across several policy sectors. Coordination, however, is often unsuccessful. Vertical coordination, inherently necessary for regional policy, is often precluded due to power struggles among supranational, national and regional governments. Likewise, conflicting policy goals and competing interests across policy sectors curtails the achievement of cross-sectoral coordination. Challenges to cross-sectoral coordination often arise since regional policy, based upon redistribution and Keynesian economics, has found itself at odds with underlying principles of the EU, namely neo-liberalism and free market competition

    Comparing cone beam laminographic system trajectories for composite NDT

    No full text
    We compare the quality of reconstruction obtainable using various laminographic system trajectories that have been described in the literature, with reference to detecting defects in composite materials in engineering. We start by describing a laminar phantom representing a simplified model of composite panel, which models certain defects that may arise in such materials, such as voids, resin rich areas, and delamination, and additionally features both blind and through holes along multiple axes. We simulate ideal cone-beam projections of this phantom with the different laminographic trajectories, appling both Simultaneous Iterative Reconstruction Technique (SIRT) and Conjugate Gradient Least Squares (CGLS) reconstruction algorithms. We compare the quality of the reconstructions with a view towards optimising the scan parameters for defect detectability in composite NDT applications

    Sociological implications of scientific publishing: Open access, science, society, democracy and the digital divide

    No full text
    Claims for open access are mostly underpinned with 1. science—related arguments (open access accelerates scientific communication); 2. financial arguments (open access relieves the serials crisis); 3. social arguments (open access reduces the digital divide); 4. democracy—related arguments (open access facilitates participation); and, 5. socio—political arguments (open access levels disparities). Using sociological concepts and notions, this article focuses strongly on Pierre Bourdieu\u27;s theory of (scientific) capital and its implications for the acceptance of open access, Michel Foucault\u27;s discourse analysis and the implications of open access for the concept of the digital divide. Bourdieu\u27;s theory of capital implies that the acceptance of open access depends on the logic of power and the accumulation of scientific capital. It does not depend on slogans derived from hagiographic self—perceptions of science (e.g., the acceleration of scientific communication) and scientists (e.g., their will to share their information freely). According to Bourdieu\u27;s theory, it is crucial for open access (and associated concepts like alternative impact metrics) to understand how scientists perceive its potential influence on existing processes of capital accumulation and how open access will affect their demand for status. Foucault\u27;s discourse analysis suggests that open access may intensify disparities, scientocentrism and ethnocentrism. Additionally, several concepts from the philosophy of sciences (Popper, Kuhn, Feyerabend) and their implicit connection to the concept of open access are described in this paper
