We first relate the random matrix model to a Fokker-Planck Hamiltonian system, such that the correlation functions of the model are expressed as the vacuum expectation values of equal-time products of density operators. We then analyze the universality of the random matrix model by solving the Focker-Planck Hamiltonian system for large N. We use two equivalent methods to do this, namely the method of relating it to a system of interacting fermions in one space dimension and the method of collective (...) fields for large N matrix quantum mechanics. The final result using both these methods is the same Hamiltonian system of chiral bosons on a circle, which manifestly exhibits the universality of the random matrix model. (shrink)

Speakers often construct their utterances based on the immediately co-present utterances of dialogue partners. They array their linguistic resources parallel to their partners¿ and activate resonance. Based on the theories of dialogic syntax and cognitive linguistics, this study undertakes to explain how speakers activate resonance and how parallelism contributes to constructing linguistic forms as well as to shaping the ongoing flow of conversation. Three phases of resonance activation are illustrated in relation to cognitive processes: (a) parallelism constituted with extension of (...) multiple categories in synthesis; (b) parallelism meeting or failing the previous speaker¿s intention due to schematization; and (c) parallelism achieved as a consequence of priming through schematization and extension. It is concluded that linguistic forms develop in the ongoing flow of socially coordinated cognition, where patterns emerge through activation of mapping relations between linguistic elements. This process is anchored in speakers¿ concepts of grammatical equivalences, ability of categorization, and grasp of linguistic conventions. (shrink)

Stance is inherent in conversational interaction and is interactional in nature. When speakers take a stance, they pay attention to both prior stances and stance relations, as well as to the anticipated consequences of their stancetaking. They manage stance relations as a way of dealing with the “sociocognitive relations” of intersubjectivity. Using the dialogic framework proposed by Du Bois, this paper shows that the discourse marker well in American English works as a resource for the management of relationships among stances. (...) With its referential and grammatical flexibility, it is uniquely characterized as a meta-stance marker because, rather than indexing a specific stance, it negotiates and regulates stance relations. Well is analyzed in two contextual categories: first, at stance divergence among utterances, and second, at stance shifts embedded in topic shift. (shrink)

The acquisition of a new skill usually proceeds through five stages, from novice to expert, with a sixth stage of mastery available for highly motivated performers. In this chapter, we re-state the six stages of the Dreyfus Skill Model, paying new attention to the transitions and interrelations between them. While discussing the fifth stage, expertise, we unpack the claim that, “when things are proceeding normally, experts don’t solve problems and don’t make decisions; they do what normally works” (Dreyfus & Dreyfus, (...) 1988, pp. 30 – 31). This leads us to offer an account of the “perspectival deliberation” that arises for experts and masters and that is distinct from the calculative deliberation characteristic of the lower stages of skillfulness.

Drawing from the Boulding''s (1956) framework for general systems theory, the need to employ richer paradigm in the study of organizations (Pondy and Mitroff, 1979) is reiterated. It is argued that a better understanding of organizational ethical behavior is contingent upon viewing organizations as symbol processing systems of shared language and meanings. Further, it is proposed that organizations, like individuals, develop into collectivities of shared cognitions and rationale, over a period of time. The study adapts Kohlberg''s (1983) model of moral (...) development to examine if organizations can be viewed as passing through different stages of moral development depending on the type of moral reasoning employed to explain their behaviors in the face of ethical crises. Several cases raising questions about the ethics of corporate behavior were researched. An instrument entitled Organization Response Analysis was constructed using statements made by various spokespersons representing five of these organizations. The instrument was administered to 246 graduate and undergraduate students of business (N = 246). Results indicated a great degree of concurrence among respondents of differing genders, levels of education and work experience in determining the stages of moral development of organizations. Limitations of the current study and implications for future research and practice are discussed. (shrink)

Early Heidegger argues that a “homogenous space of nature” can be revealed by stripping away the intelligibility of Dasein's everyday world, a process he calls “deworlding.” Given this, some interpreters have suggested that Heidegger, despite not having worked out the details himself, is also committed to a notion of deworlded time. Such a “natural time” would amount to an endogenous sequentiality in which events are ordered independently of Dasein and the stand it takes on its being. I show that Heidegger (...) was indeed committed to such a temporal realism even though his treatment of these issues is somewhat scattered and pulled in different directions. In the course of my reconstruction, I renew an interpretation of Heidegger that stresses Dasein's thrownness into nature and I answer William Blattner's powerful interpretation of Heidegger as a failed temporal idealist who was unable to derive the sequentiality of ordinary time from Dasein's non-sequential originary temporality. Heidegger did not attempt to derive sequentiality; instead, he understood it as a built-in feature of the natural universe by which Dasein's activities are constrained. World-time turns out to be a co-production of Dasein's non-sequential originary temporality and the endogenous sequentiality of events in nature. (shrink)

This paper owes its inspiration to a remark made by Professor M. Rostovtzeff; in a note in his Social and Economic History of the Roman Empire on the widespread social unrest of the first two centuries A.D., having cited other literary authorities such as Dio Chrysostom, Aelius Aristides, etc., he writes: ‘The social problem as such, the cleavage between the poor and the rich, occupies a prominent place in the dialogues of Lucian; he was fully aware of the importance of (...) the problem.’ No one, as far as I know, has attempted to collect and discuss the main passages in Lucian on this topic, and the latest writer on this aspect of Lucian reaches a conclusion quite opposed to Rostovtzeff and one which I believe to be wholly misleading. The aim of this paper is to collect and discuss the main references in Lucian to the social problem interpreting them in the light of Lucian's life and background, and the social and economic conditions of his age. In particular I shall stress the importance of the Cynic tradition as it bears on Lucian's attitude, but shall endeavour to show that this tradition is firmly rooted in practical politics and actual participation in social revolutionary movements and goes far beyond the repetition of mere ethical cliches generally ascribed to it.

This article examines the Kantian thesis of the a priori nature of our knowledge of space. Because it makes the representation of objects possible as external to us and all others, and consequently, as distinct and individualized, space (whatever its structure may be) claims the status as necessary condition and as apriori possibility of all knowledge. However, in the light of various physical, psychological and philosophical considerations, it seems that the particular structure allocated by Kant to space (i.e. uniqueness, infinity, (...) continuity, homogeneity, isotropy, Euclidean character and three-dimensional character) is neither necessary nor a priori but is rather contingent and dependent on experience. For this reason a pragmatist relativization of the transcendental approach appears to be necessary: the structure of space which makes knowledge possible is not apriori in an absolute sense, but rather, it is determined within the context of a certain practice, which is characterized by a certain mode of interaction with the environment and reveals particular empirical constraints to which this spatial structure must fit.

Abortion is an especially salient issue for considering the general problematic of religiously based conversation in the public square. It remains deeply divisive, fully thirty-four years after Roe v. Wade. Such divisiveness cannot be interpreted as merely an expression of profound differences between “secular” and “religious” voices, because differences also emerge among Christian denominations, reflecting different sources of moral authority, different accounts of moral discernment, and different judgments about the appropriate relations between law and morality in the context of pluralism. (...) As this paper explores, however, despite those differences, a generally identifiable “Christian” position concerning the moral status of abortion can be distinguished from secular philosophical judgments on the issue, which is important for Christian engagement with public policy debate.

There is a need to bring ethics and medical practice closer together, despite the risk and problems this may involve. Deontological ethics may promote sanctity of life considerations against the quality of life considerations favoured by consequentialists or utilitarians; while talk of respect for life and the value of life may point to more qualified ethical positions. This paper argues for a respect-for-life position, dismissing a utilitarian cost-benefit outlook as too simplistic; but an unqualified fixed principles approach is also ruled (...) out, both because of its unacceptable consequences in individual cases and also because of its reliance on the slippery slope argument which, it is argued, is logically and psychologically deficient. The case of genetic engineering provides an example in which the notion of respect may operate, but in which broad general principles also apply. A cautious conservatism towards accepted principles is recommended in the development of medical technologies. (shrink)

The dynamics of single populations up to ecosystems, are often described by one or a set of non-linear ordinary differential equations. In this paper we review the use of bifurcation theory to analyse these non-linear dynamical systems. Bifurcation analysis gives regimes in the parameter space with quantitatively different asymptotic dynamic behaviour of the system. In small-scale systems the underlying models for the populations and their interaction are simple Lotka-Volterra models or more elaborated models with more biological detail. The latter ones (...) are more difficult to analyse, especially when the number of populations is large. Therefore for large-scale systems the Lotka-Volterra equations are still popular despite the limited realism. Various approaches are discussed in which the different time-scale of ecological and evolutionary biological processes are considered together. (shrink)

This paper argues that self-consciousness and associated psychic consciousness emerges as a consequence of a recursive selfdirecting on itself of the cognitive centre in the human brain. The neural mechanisms and circuits underlying self-consciousness appeared and developed during biological evolution as an adaptation that increased the fitness of our social ancestors, chances of their survival, and reproduction. These mechanisms/circuits strengthened the efficiency of individuals in various social relations, enabled separation of 'I' from 'he/she' or 'them' and the formation of firstand (...) higher-order theory of mind, stimulated development of complex, recursive language, facilitated forming temporary coalitions directed to achieve a particular goal, helped to establish social hierarchies, and increased coherence and cooperativity of a social group. The reciprocal reinforcement of the development of the neural network in the brain underlying self-consciousness and of the network of various social relations and aspects was a self-driving process, one of positive feedbacks abundant in anthropogenesis.

"This title was first published in 2003.Developments in genetic science are opening up new possibilities for human beings; both the creation and the shaping of human life are now possible in the laboratory. As these techniques develop, questions are increasingly asked about how far everything that is scientifically possible should - morally, legally and socially - be pursued. Whilst much attention and policy-making has focussed on the development of regulation of technologies affecting human reproduction, regulation where plants and animals are (...) concerned is much more limited. In this book, developments in genetics are addressed in the broad sense by an international range of contributors. This includes not only issues such as eugenics and the modification of the human embryo, but also the genetic modification of plants and animals in the pursuit of commerce, agriculture and biomedical research. This book is published in association with the Society for Applied Philosophy"--Provided by publisher. (shrink)

By examining the range of factors pressing on medical professionals faced with a decision in a case of late-term abortion, it becomes apparent that the theological resources ruled out of bounds by the standard account can be considered an essential part of a truly liberating and properly supple moral account of medical decision-making. Close attention to the social, political and legal context of contemporary medicine reveals that the standard account of medical ethics, Principles of Biomedical Ethics by Beauchamp and Childress, (...) despite its universalist aspirations, disempowers rather than empowers moral decision-making by medical professionals.
