This study on the cambium of Pinus sylvestris L. examines the intrusive growth of fusiform cambial initials and its possible contribution to the tangential and radial expansions of the cambial cylinder. The location and extent of intrusive growth of the fusiform initials were determined by microscopic observations and by mathematical modeling. In order to meet the required circumferential expansion of the cambial cylinder, the fusiform initials grow in groups by means of a symplastic rather than intrusive growth, leaving no room (...) for the assumption that intrusive growth of the initials takes place between radial walls and has a direct role in the increase of the cambial circumference. Therefore, it is postulated that the fusiform initials grow intrusively between the tangential walls of the neighboring initials and their immediate derivatives and not between the radial walls of the adjacent initials as per common belief.

Reflection Principles are commonly thought to produce only strong axioms of infinity consistent with V = L. It would be desirable to have some notion of strong reflection to remedy this, and we have proposed Global Reflection Principles based on a somewhat Cantorian view of the universe. Such principles justify the kind of cardinals needed for, inter alia , Woodin’s Ω-Logic.

1. Living organisms are characterized by complexity and uniqueness of structure, as well as by specific pattern of changes during ontogenesis programmed in their own genome.2. Although general mechanisms of gene expression and regulation are well understood, our knowledge of spatial morphogenesis is rather limited and patchy despite discovery of homeotic genes.3. Developmental biology is able to explain principles of formation of neuronal network in the brain, whereas neurophysiology provides detailed information on the role of various neurotransmitters, but we still (...) do not understand the essence of consciousness, and even more self-consciousness of the man.4. Some philosophical theories trying to explain the nature of self-consciousness, such as parallelism and interactionism, are briefly discussed. (shrink)

PREFACE ln every-day activities in science and the humanities we very often compare and evaluate hypotheses, theories, and whole disciplines. ...

In the article two questions are considered: does science study values, and is science valuable, or maby harmful. The anwser for the first question is positive: science must formulate normative statements, especially in methodology. The second problem is more complicated. The author points out that the anwser depends on the previously accepted hierarchy of values.

The paper contains introductory remarks and is conceived of as a part of a larger project. First of all decisions are made as to the choice of an adequate concept of philosophy (which does not exclude other concepts of this field of interest). Among others philosophy as a very general domain of considerations is contrasted to logic and mathematics. Methods for philosophy are described in the way the natural sciences do it: methods are schemes for repeatable actions which in similar (...) circumstances result in similar or identical outcomes irrespective of the philosopher's (the performer's) views. Philosophers very often neglect repeatability and similarity of effects. Kazimierz Twardowski's method of the elimination of contradiction (cf. his paper „On the so-called relative truths”) is put forward as a paragon of further important methods of philosophy. (shrink)

In the first part of the paper three concepts of system are introduced. The first is the following ordered set: S = , where S is a given system, C is the set of its parts, R1, ..., Rk are relations between these parts, Rk+1, ..., Rk+m are relations between parts of S and its environment U. This concept does not take into account the fact that real things change. Thus it is the concept of abstract system. The second concept (...) takes changes of systems for granted. At every period i the system is slightly different. At the periods i Si is a set of sections of a real system: Si = , where {C}i is the set of sets of parts of S, {R1, ..., Rk}i and {Rk+1, ..., Rk+m}i are sets of relations. Different sections of a system are similar; the same holds for the relations and the subsequent environments. To describe the evolution of systems these similarity-relations have to be considered. Let the relations between the C's, the parts of the system, be symbolized as X, the similarity relations between the {R1, ..., Rk} pointed to by T, and the relations between the other sets of relations marked by Z. Let W be asigned to the relations between the succesive environments. SI is a system which lasts during the period I and changes in this time. The period I is in fact identical with i. The symbol SI was introduced to point to the relations S, T, Z, W, which were absent in the definition of Si. Now we have the following third concept of system: SI = . In the second part of the paper the relation X is analysed, when C consists of statements and S is a theory. The relation is to the effect that statements of later stages of a theory refer to n-tuples which exhibit more arguments that the relation spoken of at earlier stages of the theory. (shrink)

George Berkeley is one of the greatest and most influential modern philosophers. In defending the immaterialism for which he is most famous, he redirected modern thinking about the nature of objectivity and the mind's capacity to come to terms with it. Along the way, he made striking and influential proposals concerning the psychology of the senses, the workings of language, the aims of science, and the scope of mathematics. In this Companion volume a team of distinguished authors not only examines (...) Berkeley's achievements but also his neglected contributions to moral and political philosophy, his writings on economics and development, and his defense of religious commitment and religious life. The volume places Berkeley's achievements in the context of the many social and intellectual traditions - philosophical, scientific, ethical, and religious - to which he fashioned a distinctive response.

The introduction of novel diagnostic techniques in clinical domains such as genomics and radiology has led to a rich ethical debate on how to handle unsolicited findings that result from these innovations. Yet while unsolicited findings arise in both genomics and radiology, most of the relevant literature to date has tended to focus on only one of these domains. In this article, we synthesize and critically assess similarities and differences between “scanning the body” and “sequencing the genome” from an ethical (...) perspective. After briefly describing the novel diagnostic contexts leading to unsolicited findings, we synthesize and reflect on six core ethical issues that relate to both specialties: terminology; benefits and risks; autonomy; disclosure of unsolicited findings to children; uncertainty; and filters and routine screening. We identify ethical rationales that pertain to both fields and may contribute to more ethically sound policies. Considerations of preserving public trust and ensuring that people perceive healthcare policies as fair also support the need for a combined debate. (shrink)

There has been an increase in recent years in the use of empirical methods in healthcare ethics. Appeals to empirical data cannot answer moral questions, but insights into the knowledge, attitudes, experience, preferences and practice of interested parties can play an important part in the development of healthcare ethics. In particular, while we may establish a general ethical principle to provide explanatory and normative guidance for healthcare professionals, the interpretation and application of such general principles to actual practice still requires (...) interpretation and judgement. And many situations in healthcare practice are complex and may involve a variety of principles, each of which may conflict with the others. Simple surveys or interview studies may not be sufficient if we wish to develop a nuanced approach to ethical practice that can be set out in guidelines, codes or directives. We do not resolve moral questions by plebiscite. In this paper, the authors argue for the use of consensus methods to develop shared understanding of ethical practice, and they argue further for the combination of the Delphi method with the use of vignettes to illustrate the kind of situations that may occur in practice. They develop their argument in part by reference to their experience of using this approach in their recent research. (shrink)

As family physicians, general practitioners play a key role in safeguarding children. Should they suspect child abuse or neglect they may experience a conflict between responding to the needs and interests of the child and those of an adult patient. English law insists on the paramountcy of the interests of the child, but in family practice many other interests may be at stake. The authors argue that uncritical adoption of the paramountcy principle is too simplistic and can lead, paradoxically, to (...) greater harm. They argue for a more subtle and nuanced view of interests and of conflicts of interest in safeguarding children. (shrink)

Together again for the first time, Marx and Durkheim join forces in the pages of Disintegration: Bad Love, Collective Suicide, and the Idols of Imperial Twilight for a dialectical exploration of the moral economy of neoliberalism, animated, as it is not only by the capitalist chase for surplus value, but also by an immortal vortex of sacred powers. Classical sociology and psychoanalysis are reconstituted within Hegelian social ontology and dialectical method that differentiates between the ephemeral and free and the eternal (...) and fixed aspects of modern life.
