Monopolistic Intermediation in the Gehrig (1993) Search Model Revisited
No full textWe modify the basic Gehrig (1993) model. In this model, individual agents are either buyers or sellers. They can choose between joining the search market, joining the monopolistic intermediary or remaining inactive. In the search market, agents are randomly matched and the price at which exchange takes place is set bilaterally. If agents join the intermediary, buyers have to pay an ask price set in advance by the intermediary. Likewise, if sellers decide to deal through the intermediary, they get the bid price set by the intermediary. As Gehrig shows, this model has an equilibrium in which the search market and the market of the monopolistic intermediary are simultaneously open. The intermediary makes positive profits because he trades at a positive ask-bid spread, and the set of individual agents is tripartite: High valuation buyers and low cost sellers deal through the intermediary, buyers and sellers with average valuations and average costs are active in the search market, and low valuation buyers and high cost sellers remain inactive. We modify this basic model by imposing a sequential structure. We assume that the monopolistic intermediary first
has to buy the good from sellers on the input market before he can sell it to buyers on the output market. As a consequence of the sequential structure, the subgame following capacity setting has a unique subgame perfect equilibrium with an active search market. On the equilibrium path, the equilibrium analyzed by Gehrig is replicated

Lou Gehrig swinging at a pitch, ca. 1937
No full textThis black and white photograph shows Lou Gehrig in his number four jersey at bat, mid-swing. Behind him is the catcher, number 26, and out of focus roughly sixty feet in the distance is the pitcher. The photograph was taken for a May 1937 Boys' Life "Keeping Physically Fit" article written by Charles Ward Crampton that examined Lou Gehrig's swing and training. The photograph is part of a series of 13 photographs, many of which were used in the article, documenting his swing that held in the C. Ward Crampton Papers collection. At this point, this is the only photograph that has been digitized. Many of the photographs were used in the Boy's Life article.Henry Louis Gehrig (June 19, 1903 – Jun 2, 1941) was born in Manhattan and played seventeen seasons of Major League Baseball for the New York Yankees. He set several major league records, including the most career grand slams (tied by Alex Rodriguez in 2012), and most consecutive games played (surpassed by Cal Ripken, Jr.). Gehrig is chiefly remembered for his prowess as a hitter, his durability, and the pathos of his farewell from baseball, when he was stricken with amyotrophic lateral sclerosis (ALS). Gehrig was elected to the Baseball Hall of Fame in 1939, and in 1969 he was voted the greatest first baseman of all time by the Baseball Writers' Association. His jersey number was the first to be retired in professional sports. From 1934 to 1937, Crampton regularly wrote columns for the Boy Scouts of America’s magazine Boys’ Life.

The left and right sides are faded, although this could have been the photographer purposefully dodging while developing the photograph. There are a few creases along the top edge from paperclips; There are also measurements in the back indicating where the photograph should be cropped for the Boys' Life article

Die Entdeckung der Unmöglichkeit einer kritischen Theorie gesellschaftlicher Naturverhältnisse durch Thomas Gehrig
No full textIn dem vorliegenden Text wird die „Kritik des ökologischen Diskurses“ analysiert, die von Thomas Gehrig in einem monumentalen zweibändigen Werk vorgetragen wird. Darin kritisiert er fundamental die wissenschaftliche Bearbeitung des Themas in der Sozialen Ökologie. In seiner Studie zieht er 107 Texte von Autorinnen und Autoren aus dem ISOE heran, die in einem Zeitraum von 35 Jahren entstanden sind. Anhand dieser Texte versucht er seine zentralen Thesen zu beweisen: Der ökologische Diskurs lenke von der notwendigen radikalen Kapitalismuskritik ab und treibe die Modernisierung des kapitalistischen Systems voran; eine kritische Theorie der gesellschaftlichen Naturverhältnisse lasse sich philosophisch nicht begründen und sie sei wissenschaftlich unmöglich. Den Maßstab seiner Kritik entnimmt Gehrig der frühen Kritischen Theorie sowie einem von der marxistischen Interpretationsgeschichte gereinigten Marx. In der vorliegenden Analyse wird die aus einer soziologischen Dissertation hervorgegangene Studie als Dokumentation eines politischen Prozesses und eines pseudowissenschaftlichen Tribunals über die Soziale Ökologie detailliert rekonstruiert und dabei gezeigt, wie das von dem Autor beanspruchte Verfahren einer radikalen Kritik funktioniert. Diskutiert wird auch, was aus dem Gehrig’schen Werk dennoch für die Weiterarbeit am theoretischen Programm der Sozialen Ökologie zu lernen ist.Recently, the sociologist Thomas Gehrig has published his monumental two-volume opus “critique of the ecological discourse”. In a fundamental manner he criticized how the issue is treated within Social Ecology. This opus is analyzed in the text presented here. In his study Gehrig refers to 107 articles and books published by authors from ISOE in a period of 35 years. By means of these texts he tries to substantiate his central thesis: the ecological discourse distracts from the necessary radical critique of capitalism and promotes the modernization and green-washing of the destructive capitalist system; philosophically it would be impossible to justify a critical theory of societal relations to nature and therefore for him such a theory turns out to be impossible. Gehrig borrowed the criterion for his criticism from the early critical theory as well as from a Marx purified from the history of Marxist interpretations. In the analysis at hand the opus of Gehrig, emanating from a sociological dissertation, is reconstructed in detail as the documentation of a political trial and a pseudoscientific tribunal against Social Ecology. The functioning of the procedure of a radical Marxist critique claimed by the author is pointed out. Nevertheless, the analysis is discussing what can be learned from Gehrig’s opus for further research within the theoretical program of Social Ecology
Ripkin Catches and Passes Gehrig
No full textOn Tuesday, the day Cal Ripken tied Lou Gehrig\u27s record at 2130 games, I opened my mail to find the latest copy of Aethlon: The Journal of Sport Literature. On page 55 was a short story titled Streaks by David Zang. It is a very funny story of a Baltimore fan who takes it upon himself to end Cal\u27s streak and it involves the O\u27s mascot
NEW TREATMENT FOR AMYOTROPHIC LATERAL SCLEROSIS (LOU GEHRIG\u27S DISEASE
No full textThe preliminary analysis of a clinical trial of the drug riluzole, announced yesterday, shows it to be the first drug to have any impact on Amyotrophic Lateral Sclerosis (ALS) or Lou Gehrig\u27s Disease. Generally, patients survive three to five years after diagnosis of the disease. A preliminary study indicated that patients who received the drug saw an increase in survival of approximately three months
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

A Great Yankee\u27s Indian Summer: Did Lou Gehrig Experience a Temporary ALS Reversal While Playing in August 1938?
No full textNineteen thirty-eight was the last full season played by baseball slugger Lou Gehrig before amyotrophic lateral sclerosis (ALS) forced him to retire. He struggled to hit and field well for much of the season, and his final statistics -- a .295 batting average, 29 home runs, 114 runs batted in – were unusually low for him. But in mid-season, Gehrig enjoyed a streak in which he seemed to regain his previous power. This three-week stretch, not studied closely by neurologists or baseball historians until now, suggests that the “Iron Horse” may have experienced a temporary ALS reversal, which can be instructive for researchers and those coping with the disease.
