    James Gray’s three most recent features reflect on the Christian virtues of faith, hope, and love, revealed and developed through encounters with others. The Immigrant (2013) reveals the way faith informs familial commitments, social bonds, and a life-giving response to suffering and injustice. The Lost City of Z (2016) portrays a dreamer, a man whose hopeful vision of another world animates every aspect of his being. And Gray’s most recent feature, Ad Astra (2019) traces a man’s turn toward relationship as he discovers what it means to love. In each case, as Gray’s characters display these virtues, the characters transcend their boundedness, giving us a picture of the way these virtues guide us outside of ourselves, to our neighbors, and ultimately to God

    dissertationEarlier studies have demonstrated the peroxidase oxidation of the delta8-ergolines agroclavine and elymoclavine to their respective 10-hydroxy-delta9, and other derivatives. It was suggested that peroxidase may be involved in the biosynthesis of some of the ergot alkaloids. The important biosynthetic intermediate chanoclavine-I is a tricyclic analog of agroclavine and elymoclavine and might be expected to undergo similar peroxidase-catalyzed oxidations but the expected products have not observed in nature. However, the biosynthesis of the recently isolated rugulovasines could conceivably involve at some stage 10-hydrosylation such as occurs in the peroxidase oxidation of agroclavine and elymoclavine. The main objective of this investigation was to study the effect of peroxidase on chanoclavine derivatives in an attemp to clarify the possible role of this enzyme in the biosynthesis of the ergot alkaloids. The study later led in some unanticipated directions which resulted in the development of a new synthesis of lysergic acid derivatives and the isolation and synthesis of a new secoergoline alkaloid. Chanoclavine-I (and isochanoclavine-I) was found to be readily oxidized by horseradish peroxidase. However, in contrast to agroclavine and elymoclavine, this reaction provided a complex mixture of products which consisted largely of non-ergolines and only small amounts of unstable ergolines which could not be isolated and characterized. Several observations suggested that oxidation was occurring primarily at C-10 as in the tetracyclic alkaloids and that an unstable 10-hydroxy derivative was formed. The ease of decomposition of this key intermediate in ergoline biosynthesis suggested, however, that peroxidase may be more important in the biological degradation and lack of accumulation of ergolines than in their biosynthesis. Chanoclavine-I-aldehyde was rather unexpectedly found to be resistant to the action of peroxidase. For this reason, attempts were made to synthesize and determine the effects of the enzyme on its tetracyclic analog, delta-8-lysergaldehyde. All efforts to prepare this compound from elymoclavine resulted in failure as they had earlier for other investigators. However, these studies did result in the development of a three step synthesis of lysergic acid methyl ester from elymoclavine in an overall yield of approximately 30%. This is the first successful attempt to convert an ergot clavinet to a lysergic acid derivative in reasonable yield and the results indicate that the method can be used to synthesize a variety of other lysergic acid derivatives. An unidentified "ergoline acid" had been previously reported as the major alkaloid in the seeds of Ipomoea violacea var. "Pearly Gates." Several suggested that this may be a chanoclavine acid derivative. The alkaloid was isolated from the seeds of this plant in about 0.01% yield and was characterized as chanoclavine-I-acid. The compound was also synthesized from chanoclavine-I-acid. The compound was also synthesized from chanoclavine-I using a modification of the procedure used for the synthesis of lysergic acid methyl ester. Chanoclavine-I-acid was also detected in the seed of I. violacea varieties "Heavenly Blue" and "Flying Saucers" but no in those of Argyreia nervosa which suggests that it may be of value in the chemotaxonomy of the convolvulaceae family. The alkaloid was also found in small amounts of a strain of Penicillium islandicum along with chanoclavine-I and the previously reported rugulova sines. Interestingly, chanoclavine-I-aldehyde was also detected in cultures of this proposed intermediate in ergoline biosynthesis has been detected in nature

    Influence of a humidor on the aerodynamics of baseballs

    Full text link
    We investigate whether storing baseballs in a controlled humidity environment significantly affects their aerodynamic properties. To do this, we measure the change in diameter and mass of baseballs as a function of relative humidity (RH) in which the balls are stored. We then model trajectories for pitched and batted baseballs to assess the difference between those stored at 30% RH versus 50% RH. The results show that a drier baseball may be expected to curve slightly more than a humidified one for a given pitch velocity. We also find that the aerodynamics alone would add ~2 feet to the distance a moister ball is hit. However, this is compensated by a ~6 foot reduction in batted distance due to the well known change in coefficient of restitution of the ball. We discuss consequences of these results for baseball played at Coors Field in Denver, where baseballs have been stored in a humidor at 50% RH since 2002.Comment: 21 pages, 7 figures, modified and re-posted 2/2

    Beyond Indigenization: International Dissemination of Research by Majority-World Psychologists

    Analyses of the affiliations of authors of articles published in targeted samples of North American and international journals revealed trends toward increasing international publication by psychologists from countries outside the U.S., i.e., from countries in the rest of the world (ROW). Relatively few of these ROW publications came from psychologists from developing countries. Because developing countries are most numerous and represent the majority of the people in the world, their contribution to the world of psychology is important. Following a summary presentation of data for each journal for psychologists from East Asia, Latin America and the Caribbean, and South Asia (primarily India), the factors differentially deterring or promoting international publication within each region are discussed.1 Consideration of the extent to which research contributions are differentially influenced by the national economy, national language, and the state of discipline development raise questions and provide insights into the international dissemination of majority-world research
