In Tullock contests in which the common value of the prize is uncertain and the elasticity of the marginal cost of effort is increasing, the effect of changes of players’ information on the equilibrium efforts and payoffs is unambiguous: if information is symmetric, then expected effort decreases as players become better informed; in two-player contests, the expected effort of a player with information advantage is less than that of his opponent. Sharper results arise when the cost of effort is linear: (...) Under symmetric information, expected effort and payoff are invariant to changes in the players’ information. In two-player contests, both players exert the same expected effort regardless of their information, although expected effort is smaller when one player has information advantage than when both players have the same information. Interestingly, the expected payoff of a player with information advantage is larger than that of his opponent, even though he wins the prize less frequently. (shrink)

Le Tractatus particulares est un ouvrage en quatre parties attribué à Abraham Ibn Ezra (ca. 1089-ca. 1161), qui nous est parvenu en deux traductions latines. Le présent article montre que, malgré les attestations dans les incipits et les explicits des deux traductions latines, le Tractatus particulares ne peut pas être un ouvrage authentique d’Ibn Ezra, ni un recueil d’écrits de sa plume. L’essentiel du Tractatus particulares est constitué de traductions de l’arabe en hébreu, réalisées bien après la mort d’Ibn Ezra (...) et associées à son nom par la suite. L’article entend aussi montrer que la source hébraïque du Tractatus particulares était sans doute conçue comme un ouvrage astrologique complet, une sorte d’encyclopédie astrologique médiévale.

Abraham Ibn Ezra’s (ca. 1089-ca. 1161) astrological corpus includes the two versions of Sefer ha-ʿOlam (Book of the World), which represent the first Hebrew theoretical work, unique in medieval Jewish science, to discuss the theories and techniques of historical and meteorological astrology that had accumulated from Antiquity to Ibn Ezra’s time. This article surveys the content of the two versions of Sefer ha-ʿOlam and their most important doctrines as he conceived of them. The relevant material is presented chronologically: (a) the (...) ancient period; (b) the Hellenistic period; (c) Indian and Persian contributions; (d) contributions by astrologers working in the Muslim world; and (e) connections with twelfth-century Latin work on world astrology. In addition, this paper examines the contents of three additional texts by Ibn Ezra, directly concerned with word astrology: (a) the tenth chapter of Reshit Ḥokhmah (Beginning of Wisdom), where Ibn Ezra presents a series of cycles related to world astrology; (b) the astrological section of the exegetical excursus in the long commentary on Exodus 33:21, where Ibn Ezra inserts material on world astrology into his biblical commentary; (c) the introduction to Sefer ha-Moladot (Book of Nativities), where Ibn Ezra juxtaposes world astrology and the doctrine of nativities and presents a series of original ideas about world astrology.

Adversaries of Moral Luck (AMLs) are at pains to explain why wrongdoers are liable to bear burdens (punishment, compensation etc.) which are related to the harm they cause, because the consequences of what we do are a matter of luck. One attempt to solve this problem suggests that wrongdoers who cause more harm are liable to bear a greater burden not because they are more blameworthy but rather because they get the short straw in a liability lottery (represented by the (...) apparently indeterminate causal process). In this paper I argue that this attempt fails on several grounds. Apart from the fact that it is hard to see how the implementation of liability lotteries can be motivated and the fact that such scheme presupposes a political order (whereas the notion of liability does not seem to presuppose one), detaching liability from the outcomes of a culpable action undermines whichever justifications there were for imposing liability in the first place. Moreover, relying on the determination of the causal process as a good indication of the wrongdoer’s degree of culpability is mistaken, because the luck brought about through the causal process is not necessarily the only element involved in cases of harmful conduct which lies beyond the wrongdoers’ control.

Special relativity is based on the apparent contradiction between two postulates, namely, Galilean vs. c-invariance. We show that anomalies ensue by holding the former postulate alone. In order for Galilean invariance to be consistent, it must hold not only for bodies’ motions, but also for the signals and forces they exchange. If the latter ones do not obey the Galilean version of the Velocities Addition Law, invariance is violated. If, however, they do, causal anomalies, information loss and conservation laws’ violations (...) are bound to occur. These anomalies are largely remedied by introducing waves and fields that disobey Galilean invariance. Therefore, from these inconsistencies within classical mechanics, electromagnetism could be predicted before experiment proved its existence. Special relativity, it might be argued, would then follow naturally, either as a resolution of the resulting conflict or as an extrapolation of the path between the theories. We conclude with a review of earlier attempts to base SR on a single postulate, and point out the originality of the present work. (shrink)

Simple locative sentences show a variety of pseudo-quantificational interpretations. Some locatives give the impression of universal quantification over parts of objects, others involve existential quantification, and yet others cannot be characterized by either of these quantificational terms. This behavior is explained by virtually all semantic theories of locatives. What has not been previously observed is that similar quantificational variability is also exhibited by locative sentences containing indefinites with the ‘a’ article. This phenomenon is especially problematic for traditional existential treatments of (...) indefinites. We propose a solution where indefinites denote properties and are assigned locations similarly to other spatial descriptions. This Property-Eigenspace Hypothesis accounts for the correlation between the interpretations of locative indefinites and the pseudo-quantificational effects with simple entity-denoting NPs. Thereby, the proposal opens up a new empirical domain for property-based theories of indefinites, with implications for the analysis of collective descriptions, generics, negative polarity items and part–whole structure.

Abraham ibn Ezra's scientific corpus represented an exceptional case: instead of the common Latin model embodied by the scholar coming from the Christian North to the Iberian Peninsula to initiate a translation enterprise, we have in Ibn Ezra the contrary case of an intellectual imbued with the Arabic culture, who abandons al-Andalus, roams around the Christian countries and delivers in his wandering through Italy, France and England, the scientific and cultural cargo that he amassed during his youth in al-Andalus. The (...) main purpose of this article is to provide a picture of Ibn Ezra's scientific corpus as comprehensive and detailed as possible given the present state of research. The paper will fall into two main parts: Ibn Ezra's scientific work will be broken up into three main genres: Mathematics, Astronomy, Scientific Instruments and Tools; The astrological encyclopaedia; Translations from Arabic into Hebrew. In the second part, Ibn Ezra's scientific corpus will be reassembled as a whole in order to provide a global characterization, trying to point out its general organization and shape, and to indicate its main aims and special traits revealing Ibn Ezra personal contribution.

ArgumentIn recent decades a large body of scholarship on the first half of twentieth-century China has successfully shown the ways in which history and historiography had been constructed at the time, as well as the links between history, national identity, education, and politics that was forged during this period. In this paper, I examine Qing intellectual history, in particular that of the mid or “High Qing.” I discuss the development of the historiography of this field in the early twentieth century (...) by drawing on the larger developments in historiography; by demonstrating how these developments had shaped Qing intellectual history for later times; by focusing on the historical actors’ sense of the importance of “science,” being “scientific,” and “modernization”; and, by unraveling the intimate connections to older historiographical narratives going back all the way to the eighteenth and nineteenth centuries.

This paper gives a retrospective of the events in the Balkans in the last 20 years. Hence, it indicates the problems, the progress and the challenges in terms of respecting and promoting diversity. The Western Balkans has always been a very interesting region with many challenges during different historical periods. If we take into consideration all the differences and diversities in this region, then this shouldn’t strike us as surprising. During history the Balkan region has always been a crossroads of (...) many events, conflicts, changes and destructive occurrences. In order to understand the connection between ethnic and the religious diversity, as well as the future of the Western Balkan countries in terms of Euro-Atlantic integration, we need to provide some information about the political, economic and social changes in these countries during the past, especially in the last two decades. To get a better understanding of all the processes and events we need to take a look at the 90s of the last century. This period was one of the most important turning points in international relations. By the end of the Cold War there were two blocks within the societies – The Western and the Eastern, and an agreement for the Balkans to be a balance between these two blocks. This fact was important for the promotion of the concept of the nation-state, which refers generally to both of the blocks. However, changes such as the dissolution and breakdown of the USSR and Yugoslavia, as well as the official Eastern bloc fiasco, brought an increase in the individual identity of the citizens living in these countries. This was the beginning of a new era to be characterized by conflicts, wars, refugees, humanitarian crises, a large number of casualties and injured people, because of the idea that the emerging countries, especially from the Balkan region, should be nation-state countries, i.e. composed of a nation thereby ignoring the ethnic and religious differences or the unrecognized diversity of the citizens of different ethnic groups living in these countries. The establishment of the Euro-Atlantic integration concept as a key national and state priority of almost every country in this region led to the understanding of differences as an asset, and not as an obstacle for the faster integration to the EU and NATO. This fact undoubtedly contributed to the establishment of the criteria for membership, and in particular to the promotion of the rights and freedoms of minorities as most important for the integration process.

Recent years have seen the emergence of online courts and tribunals: digital platforms that enable self-represented litigants to complete electronically the entire court process, from filing through final disposition. This article proposes that the unique nature of online courts as digital interfaces enables them to implement a new strategy—diversity by design—to improve access to justice and procedural justice for a diverse population of SRLs. Reflecting a human-centered legal design approach, and building on research in human-computer interaction and digital choice architecture, (...) this strategy entails embedding diversity accommodating features in the technological design of court platforms. Specifically, building on the empirical relationship between users’ demographic attributes and their digital usability and aesthetics judgments, this article suggests that online courts can dynamically adapt their interfaces according to the attributes of a given user in ways that help diverse SRLs engage with online courts, support their effective participation in proceedings, and improve their procedural experiences. The potential impacts include enhancing SRLs’ confidence and trust in using online courts and ameliorating their ability to process information, deliberate, make informed decisions and communicate them. Finally, the article discusses concerns regarding the desirability and ethicality of dynamically adapting, that is—personalizing, court interfaces. (shrink)

The funeral procession of Sheng Xuanhuai – the renowned Qing scholar-official, financier, and “father of Chinese industrialism” – meandered through the streets of Shanghai on 18 November 1917. The funeral was a grand event, one that was purportedly documented in film, later to be distributed as the first “news short-film” in China. TheNorth China Heraldreported on the event in some detail, at times in rather florid language, and suggested that “the cortege was splendid and impressive, bringing back the days of (...) the Manchu emperors. The ceremonial costumes, the musical instruments and much more of the accoutrements dated back to the days of the Empire”. And indeed, the procession included a variety of ritual customs and insignia from Qing times: imperial banners, ancestral tablets, Buddhist and Daoist priests, paper artifacts, and much more. Simultaneously, nonetheless, other kinds of participants and objects – new and not of imperial pedigree – were part of and intermixed with the older materials: certificates of rank were carried on cars; boy scouts and college students marched alongside the priests; many of the participants arrived by train ; and as the Shanghai portion of the procession ended, it continued by steamer to Suzhou. The conclusion of theNorth China Heraldaccount, however, seems to have emphasized a dichotomy of old and new rather than a joyful mix of the two:Hundreds of men, dressed in the ancient costume of the old dynasties, bore a strong contrast to the eight behind them, sons of intimate friends of the deceased. They were on horseback and wore high silk hats, frock coats and white breeches tucked in riding boots.Truly the passing of the old and the entering of the new. This view – the old giving way to the new – was not just an off-hand journalistic analysis; it was part of a larger discourse about the nature of modernity, about progress, and about the relationship between East and West. By the early twentieth century, China was often perceived by most Westerners and Chinese alike as traditional, backward, and weak. It was, thus, commonly stated that the old was giving way to the new, should be giving way to the new, or was bound to give way to the new, if China was to survive. This kind of discourse was put forward by both Western and Chinese writers, who embraced this linear, progressive, view of the relationship between the old and the new, well before Sheng's funeral or the Qing's demise. In the aftermath of that demise, the New Culture Movement began to grow and seek solutions for the old-new nation's crisis. The Movement's rhetoric in particular advanced the need for the triumph of the new, and journals, such as New People, New Tide, or New Youth served as media for extending such views. (shrink)

Objective performance measures are vastly used in sport psychology despite their inherent limitations (e.g., unaccounted baseline differences). Founded on the nature of group goals in team sports, we aimed at developing the Perceived Performance in Team Sports Questionnaire (PPTSQ) to capture the team members’ perception of their team’s performance. Accordingly, three dimensions were hypothesized:effort investment, skills execution, andperceived outcome. To measure these dimensions, items were generated to address the players’ perception of their team performance as a whole. Four samples of (...) athletes were used to test the psychometric properties of the PPTSQ: professional (n= 231), collegiate (n= 222), professional—retest (n= 89), and mixed professional–collegiate (n= 139). Exploratory and confirmatory factor analyses were used to estimate construct and content validities. These procedures revealed a better data fit to a two-dimensional model that consists of effort investment and perceived outcome. The reliability analyses for the PPTSQ provide satisfactory evidence that the questionnaire is a reliable measure of perceived performance in team sport. Adequate internal consistency emerged for both dimensions (0.75 < ω < 0.89). Furthermore, a high correlation was obtained for temporal stability. Concurrent validity was addressed by correlating the PPTSQ scores with the Group Environment Questionnaire and the Team Assessment Diagnostic Instrument. Correlational analysis between the PPTSQ and an objective measure of performance was used to test its predictive validity. The correlations strongly support the concurrent and predictive validities of the PPTSQ. We conclude that our perceived performance questionnaire can address various objective measures shortcomings (e.g., considering base-rate biases) resulting in a more meaningful team performance metric. Implication of the PPTSQ for sport psychology research and applied work enhancement are discussed in detail. (shrink)

O questionamento da validade do princípio sistemático do kantismo trouxe inicialmente consigo tentativas de aperfeiçoá-lo e, em seguida, a suspeita de que a revolução filosófica trazida pela Crítica sela um compromisso arbitrário com os dogmas da moral e da religião, reforçada pelo fato de serem eles reabilitados na filosofia prática a despeito da interdição do dogmatismo. Ao revés dessas interpretações e a partir da retomada do "2 Préfácio" da Crítica da razão pura, argumenta-se aqui que, em Kant, moralidade e (...) sistema andam juntos. (shrink)

Comment devient-on philosophe?

Mémoire sémantique + obsession métaphysique, voilà le code génétique du philosophe. Il débute par un attentat (...) religieux, puisqu'il commence sa carrière en niant tel ou tel sacré. Bien sûr, il vaut mieux être mâle, communiquer par les livres adopter la langue dominante, écrire quand on est célibataire. Comment gagner sa vie?

Le profil du philosophe nous le révèle orphelin, vivant à l'étranger, souvent laid, jamais fou, et serial thinker, prêt à changer de philosophie pourvu qu'il reste, lui, à menacer le monde donnera ou donnera pas du sens à notre vie? Le philosophe est l'être inquiet qui pense inquiéter l'Être par deux trois mots bien aiguisés. (shrink)

While there are numerous doubts, controversies and lack of consensus on alternative definitions of human death, it is argued that it is more ethical to allow people to choose either cessation of cardio-respiratory function or loss of entire brain function as the definition of death based on their own views. This paper presents the law of organ transplantation in Japan, which allows people to decide whether brain death can be used to determine their death in agreement with their family. Arguably, (...) Japan could become a unique example of individual choice in the definition of death if the law is revised to allow individuals choose definition of death independently of their family. It suggests that such an approach is one of the reasonable policy options a country can adopt for legislation on issues related to the definition of death. (shrink)

Extraterrestrial Altruism examines a basic assumption of the Search for Extraterrestrial Intelligence (SETI): that extraterrestrials will be transmitting messages to us for our benefit. This question of whether extraterrestrials will be altruistic has become increasingly important in recent years as SETI scientists have begun contemplating transmissions from Earth to make contact. Technological civilizations that transmit signals for the benefit of others, but with no immediate gain for themselves, certainly seem to be altruistic. But does this make biological sense? Should we (...) expect altruism to evolve throughout the cosmos, or is this only wishful thinking? Is it dangerous to send messages to other worlds, as Stephen Hawking has suggested, or might humankind benefit from an exchange with intelligence elsewhere in the galaxy? Would extraterrestrial societies be based on different ethical principles, or would we see commonalities with Earthly notions of morality? Extraterrestrial Altruism explores these and related questions about the motivations of civilizations beyond Earth, providing new insights that are critical for SETI. Chapters are authored by leading scholars from diverse disciplines—anthropology, astronomy, biology, chemistry, computer science, cosmology, engineering, history of science, law, philosophy, psychology, public policy, and sociology. The book is carefully edited by Douglas Vakoch, Director of Interstellar Message Composition at the SETI Institute and professor of clinical psychology at the California Institute of Integral Studies. The Foreword is by Frank Drake. This interdisciplinary book will benefit everybody trying to understand whether evolution and ethics are unique to Earth, or whether they are built into the fabric of the universe. (shrink)

How (Not) to Be Secular is what Jamie Smith calls "your hitchhiker's guide to the present" -- it is both a reading guide to Charles Taylor's monumental work A Secular Age and philosophical guidance on how we might learn to live in our times. Taylor's landmark book A Secular Age (2007) provides a monumental, incisive analysis of what it means to live in the post-Christian present -- a pluralist world of competing beliefs and growing unbelief. Jamie Smith's book is a (...) compact field guide to Taylor's insightful study of the secular, making that very significant but daunting work accessible to a wide array of readers. Even more, though, Smith's How (Not) to Be Secular is a practical philosophical guidebook, a kind of how-to manual on how to live in our secular age. It ultimately offers us an adventure in self-understanding and maps out a way to get our bearings in today's secular culture, no matter who "we" are -- whether believers or skeptics, devout or doubting, self-assured or puzzled and confused. This is a book for any thinking person to chew on. (shrink)
