Amblyopia, or lazy eye, is a neurological vision disorder that studies have shown to affect two to five percent of the population. Current methods of treatment produce the best visual outcome, if the condition is identified early in the patient's life. Several early screening procedures are aimed at finding the condition while the patient is a child, including an automated vision screening system. This paper aims to use artificial intelligence techniques to automatically identify children who are at risk for developing (...) the amblyopic condition and should therefore be referred to a specialist, i.e., pediatric ophthalmologist. Three techniques, namely, decision tree learning, random forest, and artificial neural network, are studied in this paper in terms of their effectiveness, using metrics of sensitivity, specificity, and accuracy. The features used by the techniques are extracted from images of patient eyes and are based on the color information. The efficacy of pixel color data is investigated with respect to the measurement of the rate of change of the color in the iris and pupil, i.e., color slope features. A 10-fold stratified cross validation procedure is used to compare the effectiveness of the three AI techniques in this medical application domain. (shrink)

The so-called quantum Zeno effect is essentially a consequence of the projection postulate for ideal measurements. To test the effect, Itanoet al. have performed an experiment on an ensemble of atoms where rapidly repeated level measurements were realized by means of short laser pulses. Using dynamical considerations, we give an explanation why the projection postulate can be applied in good approximation to such measurements. Corrections to ideal measurements are determined explicitly. This is used to discuss how far the experiment of (...) Itanoet al. can be considered as a test of the quantum Zeno effect. We also analyze a new possible experiment on a single atom where stochastic light and dark periods can be interpreted as manifestation of the quantum Zeno effect. We show that the measurement point of view gives a quick and intuitive understanding of experiments of the above type, although a finer analysis has to take the corrections into account. (shrink)

In May 1956, in his eighty-second year, Jung first discussed with Gerhard Adler the question of the publication of his letters. Over many years, Jung had often used the medium of letters to communicate his ideas to others and to clarify the interpretation of his work, quite apart from answering people who approached him with genuine problems of their own and simply corresponding with friends and colleagues. Many of his letters thus contain new creative ideas and provide a running (...) commentary on his work. From some 1,600 letters written by Jung between the years 1906-1961, the editors have selected over 1,000. _Volume 1_, published in 1973, contains those letters written between 1906 and 1950.

Contains revised versions of works previously published, works not previously translated, and new translations of virtually all of Jung's writings. Prior to his death he supervised the textual revision. Several of the volumes are extensively illustrated; each contains an index and most a bibliography.

The problem of representing a single localized particle has played a crucial role in the historical development of quantum theories. In particular, the failure to construct a relativistically invariant position eigenstate was a contributing factor in the demise of the so-called relativistic quantum mechanics, in favor of quantum field theories. Nevertheless, non-locality which stems from standard accounts of Single-particle localization still presents itself as a problem in the form of Gerhard Hegerfeldt's eponymous theorem of 1974. Accepting that a link (...) may be maintained between invariance and 'objectivity,' it is shown how Hegerfeldt's paradoxical result arises in relativistic theories from a failure of objectivity of localization-the so-called 'Jericho effect'.

At the turn of the last century C.G. Jung began his career as a psychiatrist. During the next decade, three men whose names are famous in the annals of medical psychology influenced his professional development: Pierre Janet, under whom he studied at the Sappetriere Hospital in Paris; Eugen Bleuler, his chief at the Burgholzli Mental Hospital in Zurick; and Sigmund Frued, whom Jung met in 1907. It is Bleuler, and to a lesser extent Janet, whose influence is to be found (...) in the descriptive experimental psychiatry composing Volume I of the _Collected Works_. These papers appeared between 1902 and 1905l most of them are now being published in English for the first time. The volume opens with Jung's dissertation for the medical degree: 'On the Psychology and Pathology of So-Called Occult Phenomena', a study that foreshadows much of his later work, and as such is indispensable to all serious students of his work. It is the detailed analysis of the case of an hysterical adolescent girl who professed to be a medium. The volume also includes papers on cryptomnesia, hysterical parapraxes in reading, manic mood disorder, simulated insanity, and other subjects. (shrink)

The fame of the Jacobite Christian Abu Zakariyya Yahya ibn ''Adi (893 bis 974) as in influential philosopher and as en eminent apologist of the Christian faith has been founded on reputation rather than on the study of his work. When Augustin Perier compiled the first list of his writings in 1920, most of his philosophical works were believed to be lost. Most recent publications have enabled us to appraise his merits as a translator an commentator of Aristotle. But only (...) a few of his philosophical monographs were available until an important collection of his treatises was discovered inthe libraries of Tehran. This. at last, has enabled us to study in detail his contribution to logic, his treatment of physical and metaphysical problems, and his position on questions of Muslim "kalam". The Monophysite theology of Yahya ibn ''Adi, on the other hand, though better known through the studies of G Graf and A. Perier, still awaits renewed examination. The most important works in this field have not even been published. So the new inventory of his writings is intended to provide the basis for a reassessment of his merits as an Aristotelean as well as a Christian thinker.The study contains a survey of biographical data, detailed bibliographical information on manuscripts and printed works and summaries of most the unpublished texts.

Jäger, G., Fixed points in Peano arithmetic with ordinals, Annals of Pure and Applied Logic 60 119-132. This paper deals with some proof-theoretic aspects of fixed point theories over Peano arithmetic with ordinals. It studies three such theories which differ in the principles which are available for induction on the natural numbers and ordinals. The main result states that there is a natural theory in this framework which is a conservative extension of Peano arithmeti.

It is a frequent assumption that—via superluminal information transfers—superluminal signals capable of enabling communication are necessarily exchanged in any quantum theory that posits hidden superluminal influences. However, does the presence of hidden superluminal influences automatically imply superluminal signalling and communication? The non-signalling theorem mediates the apparent conflict between quantum mechanics and the theory of special relativity. However, as a ‘no-go’ theorem there exist two opposing interpretations of the non-signalling constraint: foundational and operational. Concerning Bell’s theorem, we argue that Bell employed (...) both interpretations, and that he finally adopted the operational position which is associated often with ontological quantum theory, e.g., de Broglie–Bohm theory. This position we refer to as “effective non-signalling”. By contrast, associated with orthodox quantum mechanics is the foundational position referred to here as “axiomatic non-signalling”. In search of a decisive communication-theoretic criterion for differentiating between “axiomatic” and “effective” non-signalling, we employ the operational framework offered by Shannon’s mathematical theory of communication, whereby we distinguish between Shannon signals and non-Shannon signals. We find that an effective non-signalling theorem represents two sub-theorems: Non-transfer-control theorem, and Non-signification-control theorem. Employing NTC and NSC theorems, we report that effective, instead of axiomatic, non-signalling is entirely sufficient for prohibiting nonlocal communication. Effective non-signalling prevents the instantaneous, i.e., superluminal, transfer of message-encoded information through the controlled use—by a sender-receiver pair —of informationally-correlated detection events, e.g., in EPR-type experiments. An effective non-signalling theorem allows for nonlocal quantum information transfer yet—at the same time—effectively denies superluminal signalling and communication. (shrink)

The account of meta-induction (G. Schurz, Hume’s problem solved: the optimality of meta-induction, MIT Press, Cambridge, 2019) proposes a two-step solution to the problem of induction. Step 1 consists in a mathematical a priori justification of the predictive optimality of meta-induction, upon which step 2 builds a meta-inductive a posteriori justification of object-induction based on its superior track record (Sect. 1). Sterkenburg (Br J Philos Sci, forthcoming. 10.1086/717068/) challenged this account by arguing that meta-induction can only provide a (non-circular) justification (...) of inductive predictions for now and for the next future, but not a justification of inductive generalizations (Sect. 2). This paper develops a meta-inductive method that does provide an a posteriori justification of inductive generalizations, in the form of exchangeability conditions (Sect. 3). In Sect. 4, a limitation of the proposed method is worked out: while the method can justify weakly lawlike generalizations, the justification of strongly lawlike generalizations (claimed to hold for all eternity) requires epistemic principles going beyond meta-induction based on predictive success.

In our daily lives we conceive of our surroundings as an objectively given reality. The world is perceived through our senses, and ~hese provide us, so we believe, with a faithful image of the world. But occ~ipnally we are forced to realize that our senses deceive us, e. g., by illusions. For a while it was believed that the sensation of color is directly r~lated to the frequency of light waves, until E. Land (the inventor of the polaroid camera) showed (...) in detailed experiments that our perception of, say, a colored spot depends on the colors of its surrounding. On the other hand, we may experience hallucinations or dreams as real. Quite evidently, the relationship between the "world" and our "brain" is intricate. Another strange problem is the way in which we perceive time or the "Now". Psychophysical experiments tell us that the psychological "Now" is an extended period of time in the sense of physics. The situation was made still more puzzling when, in the nineteen-twenties, Heisenberg and others realized that, by observing processes in the microscopic world of electrons and other elementary particles, we strongly interfere with that world. The outcome of experiments - at least in general - can only be predicted statistically. What is the nature ofthis strange relationship between "object" and "observer"? This is another crucial problem of the inside-outside or endo-exo dichotomy. (shrink)

For understanding human action rationality is a fundamental poin of point. A prototheory of social science elaborate the types of social action under the conceptualization of rationalization and human freedom in societies. On this way it must be distinguished two - not interchangeable - concepts of rationalization: the rationality of purpose e.g. the rational choice of means (Zweckrationalität) and the rationality of understanding (Verständigungsrationalität). Language behaviour has for this conceptualization the status of the frametheory. But actions are not identical with (...) language behaviour and are based on language external ressources. The conceptualizations of concepts of rationality are basic-assumptions for the construction of a structure-model of societal rationalization. (shrink)

This paper is mainly concerned with the proof-theoretic analysis of systems of explicit mathematics with a non-constructive minimum operator. We start off from a basic theory BON of operators and numbers and add some principles of set and formula induction on the natural numbers as well as axioms for μ. The principal results then state: BON plus set induction (...) is proof-theoretically equivalent to Peano arithmetic PA; BON plus formula induction is proof-theoretically equivalent to the system <0 of second-order arithmetic.

This proceedings volume contains a selection of revised and extended papers presented at the Second International Workshop on Nonmonotonic and InductiveLogic, NIL '91, which took place at Reinhardsbrunn Castle, December 2-6, 1991. The volume opens with an extended version of a tutorial on nonmonotonic logic by G. Brewka, J. Dix, and K. Konolige. Fifteen selected papers follow, on a variety of topics. The majority of papers belong either to the area of nonmonotonic reasoning or to the field of inductive inference, (...) but some papers integrate research from both areas. The first workshop in this series was held at the University of Karlsruhe in December 1990 and its proceedings were published as Lecture Notes in Artificial Intelligence Volume 543. The series of workshops was made possible by financial support from Volkswagen Stiftung, Hannover. This workshop was also supported by IBM Deutschland GmbH and Siemens AG. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:History-Writing as Protest: Kingship and the Beginning of Historical Narrative James G. Williams Syracuse University I. Introduction This paper is an attempt to apply René Girard's mimetic theory to the origins of historical writing, specifically the composing ofIsrael's story, vis- à-vis the origin of kingship. What I do not intend to deal with is the exact chronological beginning of historical narrative in ancient Israel. Whether or not this sort (...) of writing began immediately, it is quite clear that kingship is a problem in a way that no other office or role was in the scriptural texts. In the study of Israelite historiography and Israel's understanding of history there are many issues that have been discussed and debated. Among English speaking scholars the works of John Van Seters have been, in recent years, the most widely read on this topic.l Van Seters himself argues that the "Court History" or "Succession Narrative" in 2 Samuel and the Yahwist (J) narrative ofthe Pentateuch, or Torah, which scholars have commonly thought to be the oldest ancient Israelite history works, were composed in the exilic period (after c. 586 B.C.E.) subsequent to the completion of the "Deuteronomic work" (Josh., Judg., Books of Sam., Books of Kings). A Greek model of history writing was by then known and used by the authors of these histories previously and wrongly understood to be so old. However, prior to these historical works influenced by a Greek model was the work ofthe Deuteronomist, i.e., the books ofJoshua through Samuel, which integrated various earlier sources and traditions into a view of Israel's past that was informed by a definite theology ofhistory. This history is that of "the first known historian 1 In his approach to the texts Van Seters does not deal with any of the questions raised in the recent readings and hermeneutic approaches informed by literary theory. 92James G. Williams in Western civilization truly to deserve that designation" (Van Seters, "Search" 362). My purpose is not to argue with most of Van Seters's conclusions. In my judgment he is right to question the thesis of Hermann Gunkel and Gerhard von Rad that history writing evolved from earlier legend (Saga). I likewise agree that although there are many parallels among Israelite, Mesopotamian, Egyptian, and Hittite texts (including divine intervention in history, as shown by Bertil Albrektson), one still does not find among these other peoples a genre that could be called historiography. Van Seters borrows Johan Huizinga 's definition of history as "the intellectual form in which a civilization renders account to itself of its past" ("Search" 1). I think the definition is helpful but it lacks both a generative center and a delimitation of literary form. I propose that it be changed by extending it in two respects: (1) The intellectual form of self-understanding is rooted in the sacred as its primary problematic. In this essay I will try to show that the beginning of history writing in ancient Israel both starts from and attempts to break from the ancient sacred order as mediated through the sacral institution ofkingship. (2) Concerning literary form, history in the sense intended here requires a narrative about a nation and specific individuals (even if the divine and miracles are part of this world) that is long and continuous enough to form a coherent picture ofthe significant past. There was clearly no writing like that prior to Israelite historiography. I think the main problem in Van Seters's approach is that he misses the impulse ofhistory writing. That impulse is kingship. I don't mean this simply in the older sense, going back to L. Rost and Gerhard von Rad, that history writing begins with the cultural efflorescence that emerged in the reign of Solomon (c. 960-922 B.CE.) and used even earlier sources stemming from the period of David's rule (c. 1000-960 B.CE.).2 Kingship was, rather, an office created by the fundamental dynamic of culture, namely the sacred and its mechanisms. What made Israel different, I will argue, is that it established this office, thus becoming "like all the nations," and yet many of its distinctive witnesses... (shrink)

Résumé Citoyen allemand qui venait de vivre la deuxième guerre mondiale en Allemagne, Gerhard.A. Rauche émigre en Afrique du Sud dans les années 50 qui correspondent aux premières années de l’Apartheid. Spécialiste de Locke en philosophie et de Grisebach en littérature, il obtint deux doctorats dans ces disciplines. Critique de la philosophie analytique, de l’existentialisme et du Marxisme de l’Ecole de Francfort, il se pencha sur le problème la co-présence des communautés et de leurs relations. Il préconisa, en plein (...) régime d’Apartheid et en guise de critique, la non-absolutisation des positions identitaires pour que la vie authentique et les relations communautaires soient viables. De manière oblique et subtile, il lutta contre l’Apartheid. Sa critique philosophique qui demeure prisonnière des essentialismes et du racialisme, mériterait d’être complétée par une étude minutieuse des notions d’hospitalité et de mutualité. (shrink)

(Also titled "A Place for Peirce's Categories?"in Meaning without Analyticity.) This book arose from the author’s recent dissertation written under the Gerhard Schönrich at Munich. It focuses on Peirce’s theory of categories and his epistemology. According to Baltzer, what is distinctive in Peirce’s theory of knowledge is that he reconstrues objects as “knots in networks of relations.” The phrase may ring a bell. It suggests a structuralist interpretation of Peirce, influenced by the Munich environs. The study aims to shows (...) how Peirce’s theory of categories supports his theory of knowledge and how “question concerning a priori structures of knowledge” are transformed within this relational framework. A chief critical target is David Savan’s semiotics, specifically the idea that “the multiplicity of development of the categories” is “conditioned by nothing but the indefiniteness of the categories.” But in contrast with this, if there is any indefiniteness in the categories, they cannot fully direct their own application, and this is to say regarding them “that our knowledge is never absolute but always swims, as it were, in a continuum...” If the doctrine of continuity applies to the categories, they also have a continuum to swim in.
