    (Excerpt) My first attendance at this institute also marked the first of these Institutes. came to meet a musician classmate of mine. He was in a discussion with Edward Rechlin, the distinguished organist. As I came within earshot, Rechlin said to my classmate, Is he a musician? He said, Oh, no! No! He\u27s not a musician. Perfectly normal then, Rechlin responded

    The Basic Content of the Christian Gospel

    What is the basic content of the Christian Gospel? Why attempt to determine what it is that makes any message Gospel? As a church, we are very insistent that we are a gospel proclaiming people. If that is the case, we need to know what it is that we claim to speak when we speak. The very term gospel” is used so often that it can readily be used in place of that which it supposedly names--the elements that compose it

    C S Lewis- His Method and Message

    Get PDF
    Mr. Lewis’s real Job is being a don in the Honour School of English Language and Literature, a Tutor and Fellow at Magdalen College, Oxford, a position he has held since 1925. Bitterest opponents of his bearing a torch for Christianity say that his work in the field of literary criticism is unsurpassed. His works in this field include, “The Allegory of Love”, “Rehabilitation”, “The Personal Heresy”, and “Preface To \u27Paradise Lost’”. In the field of social theory he has written “The Abolition of Man”. In this thesis we shall concern ourselves only with the theological writings of Mr. Lewis

    Special subrings of real, continuous functions

    Some lattice-ordered subrings of C(X) containing C*(X) are examined where X is a completely regular space. Each realcompact spaceY between [v]x and ßx is associated with a lattice-ordered subring of C(X) which is isomorphic to C(Y) and contains C*(X). The cardinal number of (ßX - [v]X) is a lower bound for the cardinal number of these subrings. Every prime ideal in each of these subrings is comparable with the intersection of the subring and a maximal ideal in C(X). The structure space of maximal ideals is studied for special subrings in C(X) containing CK(X), the continuous functions of compact support, and C∞ (X), the continuous functions converging to 0 at infinity. Examples of structure spaces are given which are homeomorphic to finite point compactifications of R --Abstract, page ii

    CD163 expression in leukemia cutis

    Background: Proper diagnosis of myeloid leukemia cutis (LC) is of great clinical importance but can be difficult because no single immunohistochemical marker is adequately sensitive or specific for definitive diagnosis. Thus, a broader panel of markers is often desirable. CD163 is highly specific for normal and neoplastic cells of the monocyte/histiocyte lineage. In this study, we examined the value of CD163 in the diagnosis of acute myeloid LC. Methods: A total of 34 cases, including 18 cases of myelomonocytic or monocytic LC, 10 cases of myeloid LC without monocytic component and 6 cases of acute lymphoblastic leukemia/lymphoma (ALL), were stained with CD163. Results: CD163 was expressed in 8 of 18 (44%) of myelomonocytic or monocytic LC and 1 of 10 (10%) of other myeloid LC, but in none of the ALL cases (0/6). CD163 was highly specific (90%) for myeloid LC with a monocytic component, but showed low sensitivity in the diagnosis of both myeloid LC in general (24%) and myeloid LC with a monocytic component (44%). Conclusions: Our results suggest that CD163 has utility as a specific marker for myeloid LC in conjunction with currently used immunohistochemical stains, but should not be used alone for diagnosis.Harms PW, Bandarchi B, Ma L.

    Capabilities and Performance of Early Internationalizing Firms:A Systematic Literature Review

    Get PDF
    International-entrepreneurship researchers use a capability-based perspective to analyze the international performance of early-internationalizing firms. More than 300 papers seem to address the role of capabilities in international performance. The purpose of this study is to structure this literature and provide an orientation for researchers. First, we develop a capability-categorization model. Second, we use this model in conjunction with our systematic literature review to identify which capabilities dominate the literature and which may have been overlooked. Third, we find that, in a significant share of the papers, “capability” is defined rather loosely, which impedes theory development at the interface of the capability-based perspective and international entrepreneurship. We conclude with a research agenda for future capabilities-based international-entrepreneurship research.</p

    Limiting the effects of earthquakes on gravitational-wave interferometers

    Full text link
    Ground-based gravitational wave interferometers such as the Laser Interferometer Gravitational-wave Observatory (LIGO) are susceptible to high-magnitude teleseismic events, which can interrupt their operation in science mode and significantly reduce the duty cycle. It can take several hours for a detector to stabilize enough to return to its nominal state for scientific observations. The down time can be reduced if advance warning of impending shaking is received and the impact is suppressed in the isolation system with the goal of maintaining stable operation even at the expense of increased instrumental noise. Here we describe an early warning system for modern gravitational-wave observatories. The system relies on near real-time earthquake alerts provided by the U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA). Hypocenter and magnitude information is generally available in 5 to 20 minutes of a significant earthquake depending on its magnitude and location. The alerts are used to estimate arrival times and ground velocities at the gravitational-wave detectors. In general, 90\% of the predictions for ground-motion amplitude are within a factor of 5 of measured values. The error in both arrival time and ground-motion prediction introduced by using preliminary, rather than final, hypocenter and magnitude information is minimal. By using a machine learning algorithm, we develop a prediction model that calculates the probability that a given earthquake will prevent a detector from taking data. Our initial results indicate that by using detector control configuration changes, we could prevent interruption of operation from 40-100 earthquake events in a 6-month time-period

    Rosette‐like structures in the spectrum of spitzoid tumors

    Background Spitz nevi demonstrate a diverse spectrum of morphologies. Recently, there have been two reported examples of Spitz nevi with rosette‐like structures similar to Homer‐Wright rosettes. Rosettes have also been described in melanomas and in a proliferative nodule arising in a congenital nevus. Methods A retrospective review of 104 cases of Spitz nevi and variants (n = 51), pigmented spindle cell nevi (n = 26), combined melanocytic nevi with features of Spitz (n = 8), atypical Spitz tumor ( AST , n = 9), and spitzoid melanoma (n = 10). Results Rosette‐like structures were present in 3 of the 104 cases (2.9%), including a compound Spitz nevus, a desmoplastic Spitz nevus, and an AST . All three cases demonstrated several foci of small nests of epithelioid cells with peripherally palisaded nuclei arranged around a central area of fibrillar eosinophilic cytoplasm. Immunohistochemical staining of the three spitzoid lesions demonstrated that the rosette‐like structures express S100 protein, Melan‐A, and neuron specific enolase ( NSE ) and lacked expression of neurofilament, glial fibrillary acidic protein and synaptophysin. Conclusions While uncommon, rosette‐like structures can occur as a focal feature in Spitz nevi and AST . Rosette‐like structures may represent a normal morphologic finding in Spitz nevi, and awareness of them may prevent misdiagnosis as a neural tumor or melanoma.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99651/1/cup12192.pd
