There is a broad consensus about the fundamental role of thehippocampal system (hippocampus and its adjacent areas) in theencoding and retrieval of episodic memories. This paper presents afunctional model of this system. Although memory is not asingle-unit cognitive function, we took the view that the wholesystem of the smooth, interrelated memory processes may have acommon basis. That is why we follow the Ockham's razor principleand minimize the size or complexity of our model assumption set.The fundamental assumption is the requirement of (...) solving the socalled ``homunculus fallacy'', which addresses the issue ofinterpreting the input. Generative autoassociators seem to offer aresolution of the paradox. Learning to represent and to recallinformation, in these generative networks, imply maximization ofinformation transfer, sparse representation and noveltyrecognition. A connectionist architecture, which integrates theseaspects as model constraints, is derived. Numerical studiesdemonstrate the novelty recognition and noise filtering propertiesof the architecture. Finally, we conclude that the derivedconnectionist architecture can be related to the neurobiologicalsubstrate. (shrink)
Sophocles’s Oedipus Tyrannus shows that humans' problems do not appear when they listen to the gods, but when they listen to themselves imagining that they follow the gods. Instead of placing themselves in the service of the god, as Socrates does in Plato’s Apology, they only think that they follow the divinity, while they actually act according to their own understanding. If Sophocles’s play is a synopsis of this danger, Plato’s dialogue proposes a different attitude before divinity: instead of interpreting (...) the gods and acting on this interpretation, you would need to enter into their service by studying the meaning of their communication.

I agree with Robbert Van den Berg that Plotinus endorses Socratic intellectualism, but I challenge his view that Plotinus rejects the phenomenon of akrasia. According to Van den Berg, the only form of akrasia acknowledged by Plotinus is a conditional, or ‘weak,’ akrasia. I provide some reasons for thinking that Plotinus might have accepted complete or ‘strong’ akrasia—full stop. While such strong forms of akrasia are usually taken to conflict with Socratic intellectualism, I argue that Plotinus’s complex, dual-self psychology allows (...) a way in which he, unique among ancient philosophers, could simultaneously endorse Socratic intellectualism and hard akrasia.

This essay describes the Hungarian historical background out of which Michael Polanyi’s lifelong commitment to a liberal, democratic form of government grew. Hungary’s liberal thinkers blossomed in the nineteenth centruy, but their orientation was more political and practical than philosophical. Enlightenment ideas did not penetrate deeply into Hungarian society, which in recent centuries was hampered by its Eastern European and feudal ties. Thus Polanyi felt he had to move to more liberal countries.
Observability is a modelling property that describes the possibility of inferring the internal state of a system from observations of its output. A related property, structural identifiability, refers to the theoretical possibility of determining the parameter values from the output. In fact, structural identifiability becomes a particular case of observability if the parameters are considered as constant state variables. It is possible to simultaneously analyse the observability and structural identifiability of a model using the conceptual tools of differential geometry. Many (...) complex biological processes can be described by systems of nonlinear ordinary differential equations and can therefore be analysed with this approach. The purpose of this review article is threefold: to serve as a tutorial on observability and structural identifiability of nonlinear systems, using the differential geometry approach for their analysis; to review recent advances in the field; and to identify open problems and suggest new avenues for research in this area.

This article describes Chester Barnard, the author of The Functions of the Executive, one of the twentieth century’s most influential books on management and leadership. The book emphasizes competence, moral integrity, rational stewardship, professionalism, and a systems approach, and was written for posterity. Barnard emphasized the role of the manager as both a professional and as a steward of the corporation. His teachings drew on personal insights as a senior executive of AT&T, which saw good governance as the primary means (...) of winning public acceptance of its telecommunications monopoly. Barnard provided a conceptual scheme of the theory of organization based on the following structural concepts: the individual and bounded rationality, cooperation, formal organization, and informal organization. The principal dynamic concepts include communication, consent theory of authority, free will, the decision process, dynamic equilibrium and the inducement–contributions balance, and leadership, executive responsibility, and moral codes.

The present study endeavors to give a description of a famous case of sexual harass- ment at the workplace and critique it in terms of its embedment of an intertwined relationship between two pervasive ideologies prevalent in our society: patriarchy and consumerism. By focusing on the favorable conditions, ways of resolution, and outcomes of the lawsuit, this essay approaches the organization- al culture of Mitsubishi Motor Manufacturing of America through the lens of critical theory. Selective literature review on sexual harassment, (...) as well as general coverage of the event by the media and the parties involved demonstrate the validity of the claim that this study has made.

Dennis Gabor devised a new concept for optical imaging in 1947 that went by a variety of names over the following decade: holoscopy, wavefront reconstruction, interference microscopy, diffraction microscopy and Gaboroscopy. A well-connected and creative research engineer, Gabor worked actively to publicize and exploit his concept, but the scheme failed to capture the interest of many researchers. Gabor’s theory was repeatedly deemed unintuitive and baffling; the technique was appraised by his contemporaries to be of dubious practicality and, at best, constrained (...) to a narrow branch of science. By the late 1950s, Gabor’s subject had been assessed by its handful of practitioners to be a white elephant. Nevertheless, the concept was later rehabilitated by the research of Emmett Leith and Juris Upatnieks at the University of Michigan, and Yury Denisyuk at the Vavilov Institute in Leningrad. What had been judged a failure was recast as a success: evaluations of Gabor’s work were transformed during the 1960s, when it was represented as the foundation on which to construct the new and distinctly different subject of holography, a re-evaluation that gained the Nobel Prize for Physics for Gabor alone in 1971. This paper focuses on the difficulties experienced in constructing a meaningful subject, a practical application and a viable technical community from Gabor’s ideas during the decade 1947-1957.

The book then discusses another group of issues ("whether it is, what it is, how and why it is"), which determined the argumentation, the axiomatic ordering of the sciences, and concludes with a demonstration on the basis of concrete ...
Anything other than paraphrasing the well-known Heraclitean aphorism would not be more appropriate to portray the crux of the contribution of the three philosophers of the Budapest School, Gábor Hofer-Szabó, Miklós Rédei and Lázló E. Szabó, in the ongoing discussion of the principle of the common cause . Indeed, ‘common causes love to hide’ and for that reason critics and aspirant falsifiers of PCC find correlations which, at a first level of analysis, might lack a common cause explanation. But (...) as the authors argue such correlations do not amount to disconfirming evidence for the principle, since PCC does not specify where to search for a common cause of a correlation; it just states that there is one. PCC is neither falsifiable, nor verifiable; it is a metaphysical doctrine that can only be assessed for its plausibility in the light of theories of empirical science. This idea fosters the investigation of the existence of common causes of correlations in two fundamental physical t .. (shrink)
This interview with Gábor István Bíró reviews topics explored in his 2017 Budapest University of Technology and Economics dissertation on Polanyi’s work in economics education and on his diagrammatic film.
Gabor Forrai has written a very clear and articulate defense of internal realism, the view that the categories and structures of the world are a function of our conceptual schemes. Internal realism is opposed to metaphysical realism, the view that the world’s structure is wholly independent, both causally and ontologically, of the human mind. For the metaphysical realist, the world is one thing and the mind is another. For the internal realist, on the other hand, though the world is causally (...) independent of the human mind, the structure of the world – the individuals, kinds and categories of the world -- is a function of the human mind.

The long-periodic/infinite discrete Gabor transform is more effective than the periodic/finite one in many applications. In this paper, a fast and effective approach is presented to efficiently compute the Gabor analysis window for arbitrary given synthesis window in DGT of long-periodic/infinite sequences, in which the new orthogonality constraint between analysis window and synthesis window in DGT for long-periodic/infinite sequences is derived and proved to be equivalent to the completeness condition of the long-periodic/infinite DGT. By using the property of delta function, (...) the original orthogonality can be expressed as a certain number of linear equation sets in both the critical sampling case and the oversampling case, which can be fast and efficiently calculated by fast discrete Fourier transform. The computational complexity of the proposed approach is analyzed and compared with that of the existing canonical algorithms. The numerical results indicate that the proposed approach is efficient and fast for computing Gabor analysis window in both the critical sampling case and the oversampling case in comparison to existing algorithms.

Recent years have seen significant changes in the study of intentionality and mental representation. Twenty years ago, there was a fairly well-established research agenda, set largely by the work of Jerry Fodor. Those working to this agenda tended to assume that the study of intentionality is distinct from the study of consciousness; that the study of intentionality is the study of the propositional attitudes; that the aim of an account of intentionality should be to give a physicalist theory of it; (...) that such a theory must in some way appeal to causal relationships between intentional states and the things in the world that they are about.
