This book offers a unified treatment of selected topics in the theory of financial markets. Starting with discrete time models, Dothan introduces discrete time stochastic calculus and discrete martingale methods of intuitive simplicity to characterize attainability, completeness, pricing, and the relationship between risk and return in financial markets. Subsequently, he uses the intuition developed in conjunction with the discrete time theory to introduce continuous time calculus for continuous, jump, and mixed continuous-jump processes, and to deal with attainability, completeness, pricing, (...) and the relationship between risk and return in general continuous time models. Throughout, the exposition of the continuous time theory emphasizes the analogies between discrete time and continuous time methods and results. The book includes many examples, applications to the pricing of options and other derivative securities, and an extensive discussion of the Black-Scholes model and its most general theoretical extension.

The paper suggests a novel methodology for determining the state of legal doctrine on a particular issue by legal scholars. This methodology is inspired by the philosophical field of phenomenology. In particular, the tool of eidetic reduction developed by Edmund Husserl is applied to reach inter-subjectively valid assessments of doctrine. The methodology developed here argues that scholars who wish to discover legal doctrine on a particular issue need to first define general paradigms that explain the relevant legal field. Then, they (...) should develop a hypothesis about the law on the particular issue that concurs with the essential qualities of all these paradigms. Finally, to determine if a hypothesis about the content of the law should be accepted or rejected, it must be checked against legal sources that often include judgments. Reasoning by analogy should be used to learn from judgments with the same policy implications as the doctrine suggested by the hypothesis. The paper offers several heuristics—demonstrated with examples from international law—that can be used to find judgments that have the same policy implications without determining conclusively what these implications are.

International courts strive to enhance their legitimacy, that is, they would like the members of the international community to perceive their judgments as just, correct and unbiased even if they do not agree with their specific content. This Article argues that international courts take into account the actors they interact with, the norms they apply, and the conditions they operate under as they try to enhance their legitimacy. It demonstrates strategic behavior towards that end in the judgments of two prominent (...) international courts - the International Court of Justice and the European Court of Human Rights. International courts interact with states under their jurisdiction and with their national courts. International courts try to preserve their legitimacy vis-à-vis states; at the same time, they want to signal that states will comply with them even if they issue judgments states disagree with. International courts can cooperate with national courts and gain legitimacy from interacting with legitimate national courts. The norms that international courts apply constrain their ability to maneuver their judgments in ways that can help their legitimacy, but at the same time help legitimize their judgments. International courts use various tactics to shape their reasoning in order to improve their legitimacy. The behavior of international courts is scrutinized by the domestic public within each state. That public has certain agendas, priorities and preferences. The domestic public’s agenda is a condition that the court must respond to, but sometimes courts can also shape that agenda to their benefit. (shrink)

Studies in Abraham Joshua Heschel's Oeuvre.

Was Maimonides a radical philosopher who subtly argued for a naturalist world and who saw the obligation to keep the Torah's commandments as a social and moral obligation - or was he a conservative Jewish believer who only tried to formulate philosophical arguments in favour of a revealed religion? This question has been central to the interpretation of Maimonides from the 12th century until modern times. In the four chapters of this book, Shalom Sadik argues for a radical philosophical (...) interpretation of Maimonides. (shrink)

The transformers that drive chatbots and other AI systems constitute large language models (LLMs). These are currently the focus of a lively discussion in both the scientific literature and the popular media. This discussion ranges from hyperbolic claims that attribute general intelligence and sentience to LLMs, to the skeptical view that these devices are no more than “stochastic parrots”. I present an overview of some of the weak arguments that have been presented against LLMs, and I consider several of the (...) more compelling criticisms of these devices. The former significantly underestimate the capacity of transformers to achieve subtle inductive inferences required for high levels of performance on complex, cognitively significant tasks. In some instances, these arguments misconstrue the nature of deep learning. The latter criticisms identify significant limitations in the way in which transformers learn and represent patterns in data. They also point out important differences between the procedures through which deep neural networks and humans acquire knowledge of natural language. It is necessary to look carefully at both sets of arguments in order to achieve a balanced assessment of the potential and the limitations of LLMs. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reply to Russell's letter of 16 May 1960 by Albert Shalom EDITORIAL NOTE To illustrate a list ofrecent acquisitions in Russell (Summer 1981), we printed in facsimile Russell's letter of 16 May 1960 to Professor Albert Shalom concerning the interpretation of Wittgenstein's Tractatus LogicoPhilosophicus. The correspondence between Russell and Shalom began when Shalom wrote on I May 1960 asking whether Russell had the time and (...) inclination to read a translation of a lecture which Shalom had given the previous December in Paris. The paper was entitled "The Metaphysical Thinking Underlying Wittgenstein's Tractatus". Shalom had received "different and even contradictory appraisals" of his paper, and he very much wanted to have Russell's opinion of it. Close to the age ofninety, Russell was entering a hectic period in his life in which he worked assiduouslyfor the Campaign for Nuclear Disarmament. He had published three books in 1959 and had produced prefaces and introductions for other people. As usual, he was besieged with mail including numerous requests to read unsolicited manuscripts sent to him quite regularly. Yet he had managed to answer correspondence in a very personal way. In November 1959, he had been involved in a controversy regarding the refusal ofthe editor of Mind to review Ernest Gellner's Words and Things, a book which attacked the then prevalent philosophy of linguistic analysis and for which Russell had written the introduction. In the early months of1960, he took time out from his usual writing on the nuclear threat to reply to several articles devoted to his theory of descriptions and his ethical theory in the journal Philosophy. Russell's reply (4 May 1960) to Shalom's first letter states: "Thank you for your letter ofMay I. I shall be interested to see your paper on Wittgenstein's Tractatus, but, as I am very busy, it may be some time before I can read it carefully." On 8 May Shalom wrote back in appreciation enclosing his paper and an offprint of an article, "Qu'est-ce qu'un concept?", Revue internationale dephilosophie, 50 (1959): I-IS. The main objection raised against his paper, Shalom admitted, was that Wittgenstein was not concerned with problems of epistemology at the time of his writing the Tractatus. Nonetheless, Shalom felt that the "picture theory" of reality implies an epistemology, and he was unable to see a fallacy in his paper: "Perhaps the fact that I'm not a logician has something to do with the matter. Ifyou could enlighten me on this point I should be most grateful to you." 45 28th April 1982. 46 Russell winter 1982-83 Russell's letter of 16 May followed. On 25 May Shalom challenged Russell's interpretation. Far /rom underestimating the notion of structure, Shalom claimed that he had emphasized the notion as the key to understanding the Tractatus. "In fact, my main point is that Wittgenstein's analyses of various concepts are unintelligible unless understood as arguments in terms of the dominating idea ofstructure or form. And that is what I understand as a metaphysical argument." Shalom went on to say that his interest in any philosopher was to try to discover the chief concepts employed in the philosopher's analysis and to examine the manner in which the analysis was performed. For this reason, the later Wittgenstein was not devoid ofinterest. In a postscript, he asked Russell whether he would be in London in July ofthat year, and ifso, whether a meeting was possible. Russell replied on 18June as follows: "Thank you for your letter ofMay 25. I am sorry that at present my time and thought are so occupied with matters very remote from those with whichyour letter deals that I cannot offeryou a reasoned reply. Unfortunately, I do not expect to be in London in July so that I am afraid a meeting will hardly be possible." On 14 Shalom requested the return of his paper, and Russell complied on 19 July. Shalom is now Professor ofPhilosophy at McMaster. We invited him to comment on his exchange with Russell, particularly Russell's letter of16 May 1960. His comments take the form ofa further (and no doubtfinal) letter in the exchange.-Carl... (shrink)

The human self model suggests that the construct of self involves functions such as agency, body-centered spatial perspectivity, and long-term unity. Vogeley, Kurthen, Falkai, and Maieret (1999) suggest that agency is subserved by the prefrontal cortex and other association areas of the cortex, spatial perspectivity by the prefrontal cortex and the parietal lobes, and long-term unity by the prefrontal cortex and the temporal lobes and that all of these functions are impaired in schizophrenia. Exploring the connections between the prefrontal cortex (...) and the construct of self, the present article extends the application of the self model to autism. It suggests that in contrast to schizophrenia, agency and spatial perspectivity are probably preserved in autism, but that, similarly to schizophrenia, long-term unity is probably impaired. This hypothesis is compatible with a model of neuropsychological dysfunction in autism in a neural network including parts of the prefrontal cortex, the temporal lobes, and the cerebellum. (shrink)

Basic values explain more variance in political attitudes and preferences than other personality and sociodemographic variables. The values most relevant to the political domain are those likely to reflect the degree of negativity bias. Value conflicts that represent negativity bias clarify differences between what worries conservatives and liberals and suggest that relations between ideology and negativity bias are linear.

Although "Love your fellow as yourself" is, as Rabbi Akiva taught, the great underlying principle of the Torah, achieving the experience of this love is a profound challenge for most people. Human personality is instead often given to baseless hatred. The discourse Heichaltzu (lit., "Arm yourselves") by the fifth Lubavitcher Rebbe deals with the spiritual roots of such hatred, its practical consequences, and the remedies for it. Includes several related essays and letters, as well as extensive footnotes and references.

The application of deep learning methods to problems in natural language processing has generated significant progress across a wide range of natural language processing tasks. For some of these applications, deep learning models now approach or surpass human performance. While the success of this approach has transformed the engineering methods of machine learning in artificial intelligence, the significance of these achievements for the modelling of human learning and representation remains unclear. Deep Learning and Linguistic Representation looks at the application of (...) a variety of deep learning systems to several cognitively interesting NLP tasks. It also considers the extent to which this work illuminates our understanding of the way in which humans acquire and represent linguistic knowledge. Key Features: combines an introduction to deep learning in AI and NLP with current research on Deep Neural Networks in computational linguistics. is self-contained and suitable for teaching in computer science, AI, and cognitive science courses; it does not assume extensive technical training in these areas. provides a compact guide to work on state of the art systems that are producing a revolution across a range of difficult natural language tasks.

The language of standard propositional modal logic has one operator (? or ?), that can be thought of as being determined by the quantifiers ? or ?, respectively: for example, a formula of the form ?F is true at a point s just in case all the immediate successors of s verify F.This paper uses a propositional modal language with one operator determined by a generalized quantifier to discuss a simple connection between standard invariance conditions on modal formulas and generalized (...) quantifiers: the combined generalized quantifier conditions of conservativity and extension correspond to the modal condition of invariance under generated submodels, and the modal condition of invariance under bisimulations corresponds to the generalized quantifier being a Boolean combination of ? and ?

We formulate a Curry-typed logic with fine-grained intensionality within Turner’s typed predicate logic. This allows for an elegant presentation of a theory that corresponds to Fox and Lappin’s property theory with curry typing, but without the need for a federation of languages. We then consider how the fine-grained intensionality of this theory can be given an operational interpretation. This interpretation suggests itself as expressions in the theory can be viewed as terms in the untyped lambda-calculus, which provides a model of (...) computation. (shrink)
