The Role of Chance in Fencing Tournaments: an Agent-Based Approach

It is a widespread belief that success is mainly due to innate qualities, rather than to external forces.This is particularly true in sport competitions, where individual talent is usually considered the main, if not the only, ingredient in order to reach success. In this study, with the help of both real data and agent-based simulations, we explore the limits of this belief by quantifying the relative weight of talent and chance in fencing, a combat sport involving a weapon. Fencing competitions are structured as direct elimination tournaments, where randomness is explicitly present in some rules. Our dataset covers the last decade of international events and consists of both single competition results and annual rankings for male and female fencers under 20 years old (Junior category). Our model is calibrated on the dataset and parametrized by just one free variable 'a' describing the importance of talent - and, consequently, of chance - in competitions (a = 1 indicates the ideal scenario where only talent matters, a = 0 the complete random one). Our agent-based approach is able to reproduce the main stylized facts observed in real data, at the level of both single fencing tournaments and entire careers of a given community of fencers. We find that simulations approximate very well the real data for both Junior Men and Women when talent weights slightly less than chance, i.e. when 'a' is around 0.45. We conclude that the role of chance in fencing is unusually high and it probably represents an extreme case for individual sports. Our results shed light on the importance of external factors in both athletes' results in single tournaments and their entire career, making even more unfair the ``winner-takes-all'' disparities in remuneration which often occur among the winner and the other classified.

Sidney Coleman's Lectures on Relativity

Sidney Coleman (1937–2007) earned his doctorate at Caltech under Murray Gell-Mann. Before completing his thesis, he was hired by Harvard and remained there his entire career. A celebrated particle theorist, he is perhaps best known for his brilliant lectures, given at Harvard and in a series of summer school courses at Erice, Sicily. Three times in the 1960s he taught a graduate course on Special and General Relativity; this book is based on lecture notes taken by three of his students and compiled by the Editors.

The Recipe for Success: Repin’s Painting Barge-Haulers on the Volga and Stasov’s Conception of Russian Art

Barge-Haulers on the Volga is one of the most famous works of the Russian realist painter Ilya Repin. As I demonstrate in this article, on the one hand, it brought Repin resounding success and, on the other, it molded his creative conception. The Russian art critic Vladimir Stasov outlined the artist’s success. In March 1873, Stasov’s poetic depiction of Repin’s painting, where he expressed his admiration for Repin’s talent, focusing on specific aspects that he contended had to be included in a perfect work of Russian art, was published in the daily newspaper Sankt-Peterburgskie Vedomosti. I attempt to show that Stasov’s praise had a devastating effect on Repin’s creative process. By examining Repin’s post Barge-Haulers successful works for this pattern, I show how the painter tried to incorporate every one of the “ingredients” that Stasov outlined and ultimately created a typified group of paintings documenting life on the periphery of the Russian Empire with those features, which marked his entire career.

Felix Jiri Weinberg. 2 April 1928 — 5 December 2012

Felix Weinberg's teenage years coincided with World War II. He spent much of the war in Nazi concentration camps, starting with Terezin in December 1942, followed by Auschwitz in December 1943, and finally Buchenwald, from which he was liberated on 11 April 1945. He joined Imperial College, London as a research assistant in 1951 and completed his PhD by 1954. He was appointed to a personal chair as professor of combustion physics in 1967, and he stayed at Imperial for his entire career. Weinberg was distinguished for his optical and electrical studies of flames and his pioneering development of innovative combustion methods. He invented a family of powerful optical tools in combustion, using both broad spectrum and laser light sources. His work on electrical diagnostics led to applications of electric fields to control combustion and to improved understanding of ionization and soot formation. He developed novel combustion devices that incorporated distinctive heat exchangers, thereby permitting the ignition and burning of very low calorific fuel–air mixtures. All of these works had a propelling influence on the global evolution of environmentally benign combustion furnaces. His wide-ranging service to academia, industry and scientific societies included visiting scholar appointments at universities around the world, consultancies for petroleum, chemical, aerospace and defence organizations, and active membership on committees and boards of governance for many scientific and professional bodies. He was author, co-author or editor of four books and well over 200 papers in the scientific literature.

Early childhood practitioners’ insights on professionalism: Views from Indonesia

<p>Understanding early childhood teachers’ perspectives on professionalism is important because the notion of professionalism in early childhood is contextual and varies according to location and cultural backgrounds. Despite numerous studies on early childhood teachers’ insights on professionalism, no investigation has yet existed regarding unique environments of Indonesia. Thus this study examines Indonesian early childhood practitioners’ insights about the notion of professionalism and what constitutes the characteristics of a professional early childhood teacher. This study adopted a phenomenological method to be able to conduct an in-depth exploration of teachers’ experience and their insights about professionalism. The participants for this study were 21 kindergarten and playgroup teachers who had experienced intermediate level training in the national programme for up-skilling in South Sulawesi, Indonesia. Teachers in this study considered professionalism as a journey toward an improved state at both the pedagogical level at their actual early childhood centre and the personal level of self-improvement as a role model. The study argues that these two outputs of the journey were like parallel tracks; that lead towards improvement in both teaching performance and personal qualities. The outcome of the first track is tangible in each day of teaching performance, while the outcomes of the second track are experienced one’s entire career, or even an entire life. This echoes Urban and Dalli (2012) conclusion that being professional cannot separate the “nature of practice, thinking about practice, and thinking about oneself in this practice – making the boundaries between doing, knowing and being blurred or non-existent” (p.161). This sense of understanding professionalism as collections of interrelated actions towards an overall goal underpinned the attitudes of the teachers in South Sulawesi, Indonesia.</p>

How human capital, universities of excellence, third party funding, mobility and gender explain productivity in German political science

Using a unique panel dataset of virtually all German academic political scientists, we show that researchers become much more productive due to the accumulation of human capital and third party funding. We also show however, that while universities of excellence have more productive researchers, individuals who go there do not become more productive. Finally, we show how women publish only 9 percent less than men with the same level of prior publication experience, but are about 26 percent less productive over their entire career, as early productivity leads to later productivity, so that women increasingly fall behind. These results cannot be explained through the influence of childbearing. Rather, they support the ‘theory of limited differences’, which argues that small differences in early productivity accumulate to large differences over entire careers, as early success encourages later success. Apart from generally showing why political scientists publish more or less, we specifically identify accumulative advantage as the principal reason why women increasingly fall behind men over the course of their careers.

C. I. Lewis

Clarence Irving Lewis (b. 1883–d. 1964) is arguably the most important philosopher bridging the pragmatism of the golden age of William James and Charles Sanders Peirce and the analytic quasi-pragmatism of philosophers like W. V. Quine, Nelson Goodman, Wilfrid Sellars, and Hilary Putnam (the first three of whom were taught by him). Lewis’s philosophy as a whole reveals a unified systematic development from his dissertation in 1910, his early work in logic, the development of his epistemology in the 1920s and 1930s, his account of value theory in the 1940s and 1950s, culminating in his work in ethics, which occupied him until his death. Along the way he offered a devastating critique of American absolute idealism and offered a rich epistemology grounded in a Peircean kind of pragmatism. Early in his career Lewis wrote the first the history of logic in English, and, critical of the paradoxes of material implication, he developed an account of strict implication and a set of successively stronger modal logics, the S systems becoming the father of modern modal logic. Lewis was the most influential American philosopher from the mid-1930s until after his retirement in the 1950s. His work helped shape American philosophy as an academic endeavor and contributor to the growing acceptance of rigorous philosophical analysis and European logical empiricism. Lewis spent practically his entire career at Harvard University, bridging the Harvard of James and Royce and the modern department of Quine and Goodman. During his career he wrote six books and a hundred or so papers and reviews. A student of Josiah Royce, William James, and Ralph Barton Perry, a contemporary of Hans Reichenbach, Rudolf Carnap, and the logical empiricists of the 1930s and 1940s, and the teacher of Quine, William Frankena, Goodman, Roderick Chisholm, Roderick Firth, Sellars, and others, he played a pivotal role in shaping the marriage between pragmatism and empiricism that has come to dominate much of current analytic philosophy. Despite his significant contributions, his work soon became neglected and misinterpreted, lost in the influx of interest in Wittgenstein and the philosophy of language. Fortunately, this neglect has begun to wane.

The Footsteps of Artemis

For over two centuries, archeologists searched for a lost sanctuary of Artemis, which ancient records described as a place for worship, public announcements, and the display of political edicts. Denis Knoepfler took part in this search for his entire career—his most romantic quest finally rewarded in 2017 when the site was positively identified.
