“The world of life which is comprised of the lithosphere, the hydrosphere and the atmosphere”: this definition of the biosphere is not complete since it does not express the determining influence of living organisms on its composition, on its structure and on the processes of its continuing evolution. The part of living matter in the biosphere is relatively small (about 0.25%), but this part has a considerable influence on its structure.The biosphere should be considered as the universal source of all (...) food products without exception. Mankind's ability to feed itself depends on the productivity of this biosphere in the first place. Moreover, its condition determines not only the quantity but also the quality of nourishment. The problem is a critical one today because of the increasing pollution of the biosphere by products poured into it by various human activities. (shrink)

Recent evidence shows that dynamic instability is the dominant mechanism for the assembly of pure tubulin in vitro and for the great majority of microtubules in the mitotic spindle and the interphase cytoplasmic microtubule complex. The basic concepts of this model provide a framework for future characterization of the molecular basis of spatial and temporal regulation of microtubule dynamics in the cell and the function of microtubule dynamics in motile processes such as chromosome movement.

The dynamics of populations of self-replicating, hierarchically structured individuals, exposedto accidents which destroy their sub-units, is analyzed mathematically, specifically with regardto the roles of redundancy and sexual repair. The following points emerge from this analysis:0 A population of individuals with redundant sub-structure has no intrinsic steady-statepoint; it tends to either zero or infinity depending on a critical accident rate α c . Increased redundancy renders populations less accident prone initially, but populationdecline is steeper if a is greater than a fixed (...) value α d . Periodic, sexual repair at system-specific intervals prevents continuous decline and stabilizesthe population insofar as it will now oscillate between two fixed population levels. The stabilizing sexual interval increases with increased complexity provided this is accom-panied by appropriate levels of redundancy. The model closely simulates the dynamics of heterosis effects. Repair fitness is a population fitness: the chance of an individual being repaired is a functionof the statistical make-up of the population as a whole at that particular period. Populationsliving at α > α c either engage in sexual repair at the appropriate time or they die out. The mathematical properties of the model illustrate mechanisms which possibly played arole in the evolution of a mortal soma in relation to sexual reproduction. (shrink)

Nigel Walker’s first principle of criminalization declares that ‘Prohibitions should not be included in the criminal law for the sole purpose of ensuring that breaches of them are visited with retributive punishment’. I argue that we should reject this principle, for ‘mala prohibita’ as well as for ‘mala in se’: conduct should be criminalized in order to ensure (as far as we reasonably can) that those who engage in it receive retributive punishment. In the course of the argument, I (...) show why we should not see the criminal law as consisting in ‘prohibitions’; I explain different species of mala prohibita, and show how their commission does involve genuine wrongdoing; and I show the importance of distinguishing the question of regulation from that of sanction.

This volume insists that, if we are to properly face the challenges of the coming century, we need to re-examine international politics and development through the prism of ethics and morality. International relations must now contend with a widening circle of participants reflecting the diversity and unevenness of status, memory, gender, race, culture and class. Contributors to this volume challenge North America's privileged position in world politics, suggest initiatives for improving the quality of human existence in tangible ways, and critique (...) the conventional wisdom on how we think we can create peace and justice. Re-Framing the International shows that, when we develop projects for world reform, we must remember that the most basic prevailing assumptions of modern law, politics, and culture are by no means as obvious, natural, or progressive as we formerly thought.

The notion of autonomy commonly employed in medical ethics literature and practices is inadequate on three fronts: it fails to properly identify nonautonomous actions and choices, it gives a false account of which features of actions and choices makes them autonomous or nonautonomous, and it provides no grounds for the moral requirement to respect autonomy. In this paper I offer a more adequate framework for how to think about autonomy, but this framework does not lend itself to the kinds of (...) practical application assumed in medical ethics. A general problem then arises: the notion of autonomy used in medical ethics is conceptually inadequate, but conceptually adequate notions of autonomy do not have the practical applications that are the central concern of medical ethics. Thus, a revision both of the view of autonomy and the practice of “respect for autonomy” are in order. (shrink)

The measurement of household welfare is one of the most compelling yet demanding areas in economics. To place the analysis of inequality and poverty within an economic framework where individuals are making decisions about current and lifetime incomes and expenditures is a difficult task, made all the more challenging by the complexity of the decision-making process in which households are involved and the variety of constraints they face. This 1994 book examines the conceptual and practical difficulties of making inferences from (...) observed behaviour. It addresses the problems of making comparisons across a range of very different households and discusses how data for such comparisons should be collected. The contributions, from experts from Europe, North America and Australia, have the unifying theme that there is a strong relationship between theoretical concepts from microeconomics and the appropriate use of micro data in evaluating household welfare.

While psychopathy research has been growing for decades, a relatively new area of research is corporate psychopathy. Corporate psychopaths are simply psychopaths working in organizational settings. They may be attracted to the financial, power, and status gains available in senior positions and can cause considerable damage within these roles from a manipulative interpersonal style to large-scale fraud. Based upon prior studies, we analyze psychopathy research pertaining to 23 moral emotions classified according to functional quality and target. Based upon our review, (...) we suggest that psychopaths are high in moral emotions associated with other-directed negative signals, low in self-directed negative signals, and low in other-directed positive signals. We found no empirical articles related to self-directed positive signals. This understanding of the specific moral emotion deficits of corporate psychopaths provides greater theoretical understanding and practical implications of knowing which individuals not to promote, though more research is needed on moral emotions that are faked for manipulative reasons.

James Bohman’s account of what might be involved in thinking about ‘democracy across borders,’ and specifically of what might be involved in thinking about a potential shift from dêmos to dêmoi, compels both affirmation and resistance. His account is both elegant and sharply focussed: positive attributes that nevertheless affirm a very particular understanding of elegance, and a precise focus that manages to evade many considerations that might be considered important by people seeking to think about democracies and their futures in (...) many different situations.

The terms “modem” and “modernity”, like many other terms in common use and of wide extension, are extremely complex. And a theory of modernity should have no other goal initially than to settle this polysemy in the hope of arriving at a sufficiently rigid definition that the “thing” itself can become the object of a clearer consideration. But what is the path toward this greater clarity?

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

The development of the science of economics is closely linked to the structure of capitalism. Even though ancient and medieval thinkers had already stated a certain number of ideas in this domain, the science of economics, in the modern sense of the word, did not truly begin until the 17th Century and the early 18th Century. At that time the methodology for research in the natural sciences was developed, and the first scientific academies and societies were founded (England, France, Prussia, (...) Russia). The initial step in the development of the science of economics occurred in conjunction with this process. Moreover, the ideas of the first economists were, as a general rule, centered on the practical problems and needs of the State. And in that period the prevalent state structure in Europe was the absolute monarchy. Consequently, the first economists were, for the most part, counsellors to the sovereign, authors of studies and reports containing a variety of proposals regarding economic policy. With regard to a great many distinguished economists of the 17th and 18th Centuries, we can speak of them being “men of proposals”. (shrink)

Over the past three centuries in the West, there has been a sort of oscillation between two antagonistic visions of the world. One sees the world as being fundamentally inert, in such a manner that all hopes, dreams and technological delights are permitted. The other thinks of the world as inhabited by a spirit who consecrates all its parts by recording them in a great whole. We can think of the pantheism that sets itself in opposition to Newton's materialism or, (...) more exactly, to the materialist interpretation given to Newton in the 18th century. In the 17th century the opposite had occurred. The magic universe of the Renaissance had given place to the triumphs of the Cartesian mechanism. As for protestantism, which is said to have been one of the most powerful factors of disenchantment after the 17th century, how was one not to see it prolonged, by reaction, into a philosophy for which nature is the tangible presence of God? When Calvin wrote that nothing happens in nature that is not a direct effect of the divine will, we already see appear in the background the mystic ecstasies that Rousseau experienced in nature. For if no single leaf flutters and no breeze blows without divine intervention, then receiving the slightest sensation would mean, according to Jean-Jacques Rousseau, entering into direct contact with God.

It is with these virile words of the Martinique poet Aimé Сésaire, an expression of assurance regained, testimony to a self-confidence once stolen but then reconquered, that I would like to open my remarks.*Africa was present at the last great international philosophical meeting two years ago in Montreal. I would like here to illustrate the meaning behind this presence and to explain the reasons why we wanted to be present, in order to avoid facile misunderstandings which could have weighty consequences.

In our times changes occur so rapidly that our modes of reading even more than our modes of analysis risk being inadequate, or in any case risk lagging behind. If we wish to analyze relations between the arts and the media, the danger is in fact that we will limit ourselves to established notions or even to stereotypes which are commonly accepted by the general public. Even for persons with some awareness, information remains lacunary. Moreover, like the experts, or those (...) who pass for such, it seems that it is difficult for them to avoid a personal conception, implicit or avowed, which does not fail to influence their judgement. This is almost always the case when the matter of art is raised, even if we take the precaution of placing the term in the plural. Whether one wishes to or not, there is hardly an example where certain preferences do not make themselves known. If it is easy to reach agreement with regard to the facts, it is less easy to agree on their interpretation, especially when values are at stake. Hence the necessity to proceed by different steps and explanations to explain the relationships between arts and the media. (shrink)

The purpose of this article is to attempt to discern better the situation of art in contemporary society. To do this we will examine essentially the exterior forces which influence it. These multiple and diverse evolutionary forces are in a certain manner centripetal, and ultimately they modify our concepts of art as such. Without going so far as to state that contemporary society has completely overturned our ideas on this question, signs of change are nevertheless visible which challenge fundamental characteristics (...) up until now attributed to art.

It is some 900 years before Christ that we find the most ancient traces of two innovations which were to have incalculable consequences for the future of mankind. The evolution of civilization has, in fact, been marked by a clean break located at the era when man discovered the rudiments of agriculture and animal husbandry and began to produce his own food. Whereas for the three million years during which he had to provide for his needs exclusively through hunting, fishing (...) and gathering, his progress was extremely slow, the adoption of a new way of life based on agriculture and animal husbandry allowed man to transform himself in less than twelve thousand years from deer hunter into astronaut.

One of the dominant characteristics of Western philosophical and literary history of the last two centuries is that the object of desire (in the novel) and the object of perception (in epistemology) have been made to reveal aspects which are more complex than the classical age had suspected. With Descartes, everything was clear: the object is but a portion of extension. But with Kant things already become more complicated: the object has a mysterious. en-soi (an sich-in itself) which escapes us. (...) And the object of desire, in literature, acquires such a mystic character that it loses its status of creature. “For what the romantic lover seeks is not really the beloved”, writes Eric Heller. “Intermingled with his erotic craving, inarticulate, diffuse, and yet dominating it, is the desire for spiritual salvation.” It is no longer the object (the creature) which one wishes to embrace, but the invisible reality mirrored in it. Desire does not tend so much toward objects as toward what lies beyond these objects where, it believes, it will find its salvation. (shrink)

If we attempt to unify the theoretical efforts that appreciate a specific social activity in play, we can sketch the perspective of an entire anthropology of play into cohesive parts deriving from the knowledge of collective experience. This preoccupation is, in fact, two-fold. On the one hand is the comprehensive description of the relationship between life styles and their stylizations in everyday practices and customs as well as in cultural works, and on the other are social sensitivities and representations that (...) are relatively shared by individuals grouped in human communities. This very general framework encourages situating the presence of play as one of the concrete manifestations of an emotional core, converting primitively negative impulses into attractive forces which, because of this, becomes the seat of all human interaction and agitation, the energetic heart of social power.

At first glance, the formulation of the principle of inertia—not. yet complete with Galileo, more precise with Gassendi, finally systematic with Newton—seems to constitute but one of the aspects of a process of deep transformations at the end of which traditional cosmology was replaced by various world systems. These transformations—or, to use a more classic term, this “ scientific revolution” —have been the object of numerous works, a list, of which would alone fill the pages of a thick volume. But (...) the principle of inertia itself, a principle about which can be said without exaggeration that it expressed the essence of this revolution at the same time as it stimulated it, has perhaps not received all the attention it deserves. And especially the impact of this principle on Western culture has not been fully measured. True, Alexandre Koyré has always insisted on the fact that, by reducing movement to a state like that of the state of rest, the principle of inertia expressed a new vision of the world more than a scientific result. But his admirable analyses deal more with the slow advent of the priciple of inertia among the natural philosophers who preceded, accompanied and then followed Galileo than with the theological, philosophical and literary impact of this principle. Moreover, by examining this impact, we discover that it is necessary to make a distinction between Euclidian space and absolute space, a distinction which is frequently implicit with certain scientific historians, but, and this must be emphasized, is more often ignored.

We construct a class of relations on computable structures whose degree spectra form natural classes of degrees. Given any computable ordinal and reducibility r stronger than or equal to m-reducibility, we show how to construct a structure with an intrinsically invariant relation whose degree spectrum consists of all nontrivial r-degrees. We extend this construction to show that can be replaced by either or.

This article describes the Vaccine/Injury Project Corpus, a collection of legal decisions awarding or denying compensation for health injuries allegedly due to vaccinations, together with models of the logical structure of the reasoning of the factfinders in those cases. This unique corpus provides useful data for formal and informal logic theory, for natural-language research in linguistics, and for artificial intelligence research. More importantly, the article discusses lessons learned from developing protocols for manually extracting the logical structure and generating the logic (...) models. It identifies sub-tasks in the extraction process, discusses challenges to automation, and provides insights into possible solutions for automation. In particular, the framework and strategies developed here, together with the corpus data, should allow “top–down” and contextual approaches to automation, which can supplement “bottom-up” linguistic approaches. Illustrations throughout the article use examples drawn from the Corpus. (shrink)

A simple model, illustrating the transition from a population of free swimming, solitary cells to one consisting of small colonies serves as a basis to discuss the evolution of the cooperative group. The transition is the result of a mutation of the dynamics of cell division, delayed cell separation leads to colonies of four cells. With this mutation cooperative features appear, such as synchronised cell divisions within colonies and coordinated flagellar function which enables the colony to swim in definite directions. (...) The selective advantages under given, environmental conditions are defined and the periods necessary for complete allelic replacement in small populations are calculated for asexual and sexual reproduction. The assumption of a steady-state population during allelic substitution is critically considered, particularly under conditions of competition. It is shown that density-dependent population control must operate in the process of selection. Sexual reproduction slows down the rate of selection even though all cells dre haploid. This phenomenon can be explained in general terms of `organizational dominance', where individual units coordinate the function of their neighbours which may be of a different allelotype.Cooperativity is pointed out as an a priori systemic feature which resides in the sub-units of systems, group formation and coordination appears thus as an almost inevitable event. A particular type of system described as ‘closed cycle of positive fitness interaction’ is discussed in more detail. It has the remarkable feature that its members cannot compete with each other; selection takes place between whole cycles .Gonium has a wide spectrum of `somatic plasticity' which enables it to assume various colonial configurations depending on physiological and environmental conditions. This feature can be explained as the result of dynamic flexibilities on the macro-molecular level. The particular relationship between the vast, molecular complexity and the relative simple dynamics of the cell cycle must lead eventually to the genetic fixation of an environmentally induced phenotype.

Heidegger's affirmation is categorical: “… the thinking expressed in Being and Time is against humanism”. Heidegger's thesis is not only categorical, it is also polemical. He maintains that the humanist conception does not grasp man's essence, and it is for this reason that he is opposed to humanism, which is a doctrine that “has not thought profoundly enough of man's humanitas.

Tracing the broad outline of European art history means presenting the different methods considered essential to the formation of this discipline. Historiographical research arrives quite naturally at a criticism of the methods themselves and at a search for a broader horizon.To the extent that the historian is involved with the thinking and the problems of his age, his methods reveal personal and conjunctural concepts and ideas which will guide the reflections of his successors ; these successors will modify and correct (...) the concepts received in order to adapt them to new experiences and questions. Or they will add others which are more apt to supply the answers sought. The means of analysing art history today are the fruit of four centuries of discussion during which certain normative criteria, traditional theories and underlying concepts were called into question while at the same time, though being sometimes exported to other areas of the world, they have demonstrated a tenacious degree of longevity. But perhaps a brief recapitulation might be helpful here. (shrink)

I am, by profession, a “literary scholar”, in contrast to “scientists”. More precisely, I am a specialist in ancient Greek literature. Yet, in an age such as ours in which so often there is discussion of the standing of the various academic disciplines, of the differences implied by their methods and their needs, and of the means for making them work together, it seems to me more and more that very serious confusion is tending to becloud some essential definitions: that (...) of the study of literature in general, but even prior to that, the very definition of literature itself. It is very important to reach some understanding if we hope to avoid losing the richness of research and the very vitality of culture in the broadest sense of the term. (shrink)

On the occasion of the one hundredth anniversary of the death of Marx, has not the moment come at last to render an equitable judgment, of the type which only the passage of time allows us to formulate, on the man whom we do not know how to describe— philosopher, economist, historian, sociologist, politician, theoretician of the worker movement, reformer, revolutionary or prophet? And this judgment, which will take everything and examine it before putting all things in their proper place, (...) could it not take the form of a response to the famous question: what is dead and what is still living today in that work which is as monumental as it is diverse since it touches every domain of knowledge and action?

What is truth? This famous question does not express merely the anguish—or the detachment—of the person who, at the moment of choosing, hesitates between deciding for one or the other of the contradictory theses being presented. At a second level, the question no longer concerns merely the content but the very conditions for the decision: in what name, by virtue of what criterion do we say that a given assertion is true while its contrary is false? We could limit ourselves (...) to recognizing in this second phase a particular species of philosophical questioning, which proceeds reflexively from the constituted to the constituent, from the given of the experience to the conditions for the possibility of the experience in general. But in the question about truth, a prejudicial difficulty inevitably arises which is proper to this question and makes it incomparable to any other. How can I be assured of the truth of my assertions about truth without presupposing at the same time a theory for that truth which I am in tact in the process of seeking? In other words, any question about truth moves in a circle since, by demanding a true answer, just like every question it implies that the questioner already knows what is truth at the very moment when he is asking what it is.
