Statistical methods are discussed, which are used in the analysis of point patterns. Special attention has been paid to their application in ecological research. Some new procedures are presented, which seem to be better compatible with the needs of the ecologist.It is pointed out that patterns can usually be described in terms of an appropriate trend surface as well as in terms of mutual interactions. This circumstance restricts the value of the analysis of point patterns for ecological research in tracing (...) the mechanisms which are connected with the distribution of individuals. (shrink)

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'.

The structure of Chiodi's book is based on Vuillemin's important hermeneutical thesis that existentialism is one more step in the program of the romantics to give an absolute foundation to finite reality through the establishment of necessary relations between subjectivity and being. These relations, once revealed, would dispel the facticity and contingency in which the natural world is enshrouded. The role of Heidegger in this tradition involves one further dialectical twist, since Heidegger centers all Western Philosophy, including his own, around (...) the problem of ground in the manner proposed by the romantics. The suggested dialectical twist is then Heidegger's Kehre, a step beyond the radical contingency of Dasein in Sein und Zeit. Indeed, this contingency, once reached, shows unequivocally the failure of the romantic program. The ground cannot be ontologically connected with any object nor with the subject; it is rather the necessary history of the ground that determines all categorial differentiations in the world, including the reflective differentiation of subject-objects. Thus it becomes important to distinguish Heidegger from Hegel since, in both, history and necessity are characteristics of the ground. Chiodi gets to the bottom of this matter by pointing to the transfer of negativity from the process of history to the end of history. For Heidegger what is necessary is the repeated withdrawal of the ground so that it may never be confused with that which is known in any revelation or through all of them. This move, though clear, would still leave a fundamental ambiguity in the later philosophy of Heidegger: language, which acts as messenger from the ground to the world, must reflect the superabundance of Being from the standpoint of the ground while it only reflects possibilities of being from the standpoint of the world. This is an ambiguity that Heidegger would want to maintain. Chiodi's interpretation of Heidegger as a neo-platonist totally destroys this ambiguity and with it the very delicate balance created by Heidegger between infinite meaning and the ability of finite words to dwell upon it.--A. de L.

Synthetic biology is an emerging technology that asks for inclusive reflection on how people frame the field. To unravel how we can facilitate such reflection, this study evaluates the Frame Reflection Lab. Building upon playfulness design principles, the FRL comprises a workshop with video-narratives and co-creative group exercises. We studied how the FRL facilitated frame reflection by organizing workshops with various student groups. Analysis of 12 group conversations and 158 mini-exit surveys yielded patterns in first-order reflection as well as patterns (...) in second-order reflection. Also patterns in participants’ framing of synthetic biology could be induced; participants’ viewpoints converged to some extent, yet with openness to individual viewpoint differences. Although the FRL method fortified the reflection processes of participants, the narratives and the workshop’s flexible format could inhibit the reflection too. Therefore, we advise designers of future frame reflection methods to apply stronger conversational facilitation and narratives of slightly mysterious yet identifiable narrators, in case e.g. video-narratives are created and used to scaffold the reflection process. Nevertheless, we argue that the use of a playful frame reflection method like the FRL could function well as a step to precede more application-specific deliberation or decision-making on synthetic biology and as a method for the collection of contemporary citizen viewpoints plus rationales underlying these, for the further responsible development of the emerging field.

The appearance of Jesus Christ in his time was inevitable. Plato's ideas were to find a material embodiment on earth. The image of Christ as a balance, the harmony of light-spirit and darkness-matter, is the materialization of the ideal image.

This paper focuses on natural dualities for varieties of bilattice-based algebras. Such varieties have been widely studied as semantic models in situations where information is incomplete or inconsistent. The most popular tool for studying bilattices-based algebras is product representation. The authors recently set up a widely applicable algebraic framework which enabled product representations over a base variety to be derived in a uniform and categorical manner. By combining this methodology with that of natural duality theory, we demonstrate how to build (...) a natural duality for any bilattice-based variety which has a suitable product representation over a dualisable base variety. This procedure allows us systematically to present economical natural dualities for many bilattice-based varieties, for most of which no dual representation has previously been given. Among our results we highlight that for bilattices with a generalised conflation operation. Here both the associated product representation and the duality are new. Finally we outline analogous procedures for pre-bilattice-based algebras. (shrink)

The starting point of my analysis is the complexity of contemporary society. Complexity here refers more in particular to social complexity: the type of complexity that emerges from the relationships between human beings and the myriad of options and possibilities that exist in our society. A systems theoretical account of complexity elicits that this 'social abundance' necessitates selections. One way of enabling selections, and hence the reduction of complexity, is the formulation of norms. The central thesis of this account follows (...) from this observation: social complexity is a source of normativity, in the sense that social complexity generates – among others – normativity. Dealing with social complexity requires selections and a considerable range of selections, at their turn, require norms. From a somewhat different angle, we could say that social complexity entails both freedom of choice and force of choice. It is this combination of freedom and force that confronts our society with a profound problem. It translates, so to speak, social complexity into uncertainty: how to deal with all these options and possibilities, how to shape our interactions? An important aspect of the problem is the abundance of colliding heteronymous norms and a simultaneous lack of ethical norms that do not compromise our individual autonomy. The analysis of this ethical state of affairs draws upon the work of Zygmunt Bauman. The paper tentatively seeks to outline the social theoretical requirements of an ethic that takes issue with the uncertainty of choice. (shrink)

Conceived as a set of preliminary explorations to a future study of the problem of meaning and reference by the author, these "inquiries" clarify some questions raised by the specialists in linguistics, caution us about other questions that seem only too easily settled, and generally show, with great abundance of detail, the status of contemporary research on language. Much like Husserl's Logical Investigations, which pioneered the study of correspondences between grammar and logic-ontology, these explorations proceed in a zigzag sometimes emphasizing (...) semiotic issues ; other times tackling important syntactic and semantic problems ; and once coming close to an ontological characterization of language and of the human subject insofar as it uses language. Two features of this work are noteworthy. The first is the abundance of documentation as shown in the multitude of notes: the efforts of Ferrater Mora will spare many hours of work for those who need a guide in "the labyrinth of language." A second feature is the virtuoso performance by the author in the manipulation of, and exemplifications from, a variety of languages. Indagaciones sobre el Lenguaje certainly deserves publication in English.--A. de L. M. (shrink)

This paper reviews the relationship between organisational leadership, corporate governance and business ethics, and considers the implications for management. Business ethics is defined, and the causes and consequences of unethical behavior are discussed. Issues pertaining to leadership, subordinate and organisation responsibility for business ethics are considered. The changing role of business leaders and the new concept of ''corporate governance'' are examined, with an increasing importance being placed on ethical and socially responsible attitudes towards business. Organisational effectiveness and organisational efficiency, formerly (...) central issues for practising managers, with directors thinking in terms of goal achievement for their respective organisations, have now been augmented by an awareness of issues in business ethics, and a requirement for members of the corporate governance to behave in more socially responsible ways. A secondary aim of the paper is to introduce an approach which illustrates how corporate governance and management could deal with some of the moral dilemmas that they may have to face. (shrink)

The present study investigated whether individual differences between psychologists in thinking styles are associated with accuracy in diagnostic classification. We asked novice and experienced clinicians to classify two clinical cases of clients with two co-occurring psychological disorders. No significant difference in diagnostic accuracy was found between the two groups, but when combining the data from novices and experienced psychologists accuracy was found to be negatively associated with certain decision making strategies and with a higher self-assessed ability and preference for a (...) rational thinking style. Our results underscore the idea that it might be fruitful to look for explanations of differences in the accuracy of diagnostic judgments in individual differences between psychologists (such as in thinking styles or decision making strategies used), rather than in experience level.

We used computer simulations to study the possible role of the dispersion of cellular coupling, refractoriness or both, in the mechanisms underlying cardiac arrhythmias. Local ischemia was first assumed to induce cell to cell dispersion of the coupling resistance (Case 1), refractory period (Case 2), or both of them (Case 3). Our numerical experiments based on the van Capelle and Durrer model showed that vortices could not be induced by cell to cell variations. With cellular properties dispersed in a patchy (...) way within the ischemic zone, a single activation wave could give rise to abnormal activities. This demonstrates the stability of the wave front under small inhomogeneities. Probabilities of reentry, estimated for the three cases cited above showed that a severe alteration of the coupling resistance may be an important factor in the genesis of reentry. Moreover, use of isochronal maps revealed that vortices were both stable and sustained with an alteration of the coupling alone or combined with a reduction of the action potential duration. Conversely, simulations with reduction of the refractoriness alone, inducing only transient patterns, could exhibit functionally determined reentries. (shrink)

Intended as an introduction of the phenomenological writings of Pfänder to English-speaking readers, this work contains two major essays and two minor selections by Pfänder, plus an introduction and two appendixes by Spiegelberg. Because of its composition, this book should be classified as a Pfänder's anthology centered around a main essay titled "Motives and Motivation." As reasons for the translation and publishing of this main essay, Spiegelberg mentions first its influence on Ricoeur's phenomenology of the will, and secondly its topical (...) affinity with R. S. Peter's The Concept of Motivation, a work considered by Spiegelberg as capable of restoring the importance of the will in Anglo-American philosophy. The other major essay is, curiously enough, the introduction to a text-book in logic written by Pfänder in response to Husserl's own request. The two essays, though different, are not unrelated; they represent the theoretical and practical sides of the unique phenomenological method of constitution. The presence of these two essays, side by side, in this volume raises in fact the question of Pfänder's own understanding of the theoretical unity of thought and action that is the key to phenomenological subjectivity. A clarification of Pfänder's thought on this unity would certainly help us evaluate his contribution to phenomenology. Spiegelberg himself depicts Pfänder as a reasonable phenomenologist, accurate in analysis and moderate in speculative claims, a sober figure indeed in an environment sometimes seen as prone to intellectual excesses.--A. de L.

There is a popular hypothesis that performance on implicit and explicit memory tasks reflects 2 distinct memory systems. Explicit memory is said to store those experiences that can be consciously recollected, and implicit memory is said to store experiences and affect subsequent behavior but to be unavailable to conscious awareness. Although this division based on awareness is a useful taxonomy for memory tasks, the authors review the evidence that the unconscious character of implicit memory does not necessitate that it be (...) treated as a separate system of human memory. They also argue that some implicit and explicit memory tasks share the same memory representations and that the important distinction is whether the task (implicit or explicit) requires the formation of a new association. The authors review and critique dissociations from the behavioral, amnesia, and neuroimaging literatures that have been advanced in support of separate explicit and implicit memory systems by highlighting contradictory evidence and by illustrating how the data can be accounted for using a simple computational memory model that assumes the same memory representation for those disparate tasks.
