In der folgenden Übersicht wird versucht, die wissenschaftstheoretischen Tätigkeiten in den Niederlanden, insbesondere auf den Gebieten der Logik und Grundlagenforschung, Philosophie der Naturwissenschaften, Philosophie der Geschichtswissenschaft und der Sozialwissenschaften zu skizzieren. In einer Schlußbetrachtung werden die allgemeinen methodologischen Fragestellungen und die daraus sich ergebenden neuen Möglichkeiten einer Wissenschaftstheorie erörtert.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be used (...) by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

This study investigates the ability of individuals with psychopathy to perform passive avoidance learning and whether this ability is modulated by level of reinforcement/punishment. Nineteen psychopathic and 21 comparison individuals, as defined by the Hare Psychopathy Checklist Revised (Hare, 1991), were given a passive avoidance task with a graded reinforcement schedule. Response to each rewarding number gained a point reward specific to that number (i.e., 1, 700, 1400 or 2000 points). Response to each punishing number lost a point punishment specific (...) to that number (i.e., the loss of 1, 700, 1400 or 2000 points). In line with predictions, individuals with psychopathy made more passive avoidance errors than the comparison individuals. In addition, while the performance of both groups was modulated by level of reward, only the performance of the comparison population was modulated by level of punishment. The results are interpreted with reference to a computational account of the emotional learning impairment in individuals with psychopathy. (shrink)

When Pythodorus in 411 B.C. moved in the Athenian Assembly his decree that Commissioners should be elected to draft measures for the security of the State, Cleitophon added a rider instructing the Commissioners προσαναξητσαι κα τος πατρονς νμονς ος κλειδθνης θηκεν τε καθδτη τν δημοκραταν, πως ν κοσαντες κα τοτων βολεσωντααι τ ριστον. The instruction appears to have struck Aristotle as paradoxical and inept, for he has appended an explanation of Cleitophon's reasons which is also a criticism: ς ο δημοτικν (...) λλ παραπλησαν οσαν τν Kλεισθνους πολιτεαν τ Σλωνος. Indeed one would never imagine that the constitution of Cleisthenes as described by Aristotle could have been seriously suggested as a model or a repertory of precedents for legislators intent, like Cleitophon's friends, on restoring the πτριος πολιτεα, which it obviously disestablished; and the conjunction of τοĐς πατρουσ with τε καθστη τν δημοκραταν might seem to make the proposal a challenge or a mockery. Aristotle had already given his opinion that by Cleisthenes' innovations δημοτικωτρα πολĐ τς Σλωνος γνετο πολιτεα He recognized democratic features in Solon's laws, but they lay in the redress of social wrongs or in the method of administering justice rather than in the organization of the government; he regarded Solon's political changes, not as the establishment of democracy proper, but as a reform, conservative rather than revolutionary, of existent institutions. His comment on the rider implies that he would not have corrected Cleitophon if he had referred the Commissioners to Solon's ancestral laws, but to refer them to Cleisthenes' must, he thought, be ignorance, irony, or idiosyncrasy.

As neurophysiological investigations of sleep cycle control have provided an increasingly detailed picture of events at the cellular level, the concept that the sleep cycle is generated by the interaction of multiple, anatomically distributed sets of neurons has gradually replaced the hypothesis that sleep is generated by a single, highly localized neuronal oscillator.Cell groups that discharge during rapid-eye-movement (REM) sleep (REM-on) and neurons that slow or cease firing during REM sleep (REM-off) have long been thought to comprise at least two (...) neurochemically distinct populations. The fact that putatively cholinoceptive and/or cholinergic (REM-on) and putatively aminergic (REM-off) cell populations discharge reciprocally over the sleep cycle suggests a causal interdependence.In some brain stem areas these cell groups are not anatomically segregated and may instead be neurochemically mixed (interpenetrated). This finding raises important theoretical and practical issues not anticipated in the original reciprocal-interaction model. The electrophysiological evidence concerning the REM-on and REM-off cell groups suggests a gradient of sleep-dependent membrane excitability changes that may be a function of the connectivity strength within an anatomically distributed neuronal network. The connectivity strength may be influenced by the degree of neurochemical interpenetration between the REM-on and REM-offcells. Recognition of these complexities forces us to revise the reciprocal-interaction model and to seek new methods to test its tenets.Cholinergic microinjection experiments indicate that some populations of REM-on cells can execute specific portions of the REM sleep syndrome or block the generation of REM sleep. This observation suggests that the order of activation within the anatomically distributed generator populations may be critical in determining behavioral outcome. Support for the cholinergic tenets of the reciprocal-interaction model has been reinforced by observations from sleep-disorders medicine.Specific predictions of the reciprocal-interaction model and suggestions for testing these predictions are enumerated for future experimental programs that aim to understand the cellular and molecular basis of the mammalian sleep cycle.

A simple transposition in the text would, I venture to suggest, remove one or two of the many difficulties of this obscure chapter.
