Errors and their consequences are typically studied by investigating changes in decision speed and accuracy in trials that follow an error, commonly referred to as “post-error adjustments”. Many studies have reported that subjects slow down following an error, a phenomenon called “post-error slowing” (PES). However, the functional significance of PES is still a matter of debate as it is not always adaptive. That is, it is not always associated with a gain in performance and can even occur with a decline (...) in accuracy. Here, we hypothesized that the nature of PES is influenced by one’s speed-accuracy tradeoff policy, which determines the overall level of choice accuracy in the task at hand. To test this hypothesis, we had subjects performing a task in two distinct contexts (separate days), which either promoted speed (hasty context) or cautiousness (cautious context), allowing us to consider post-error adjustments according to whether subjects performed choices with a low or high accuracy level, respectively. Accordingly, our data indicate that post-error adjustments varied according to the context in which subjects performed the task, with PES being solely significant in the hasty context (low accuracy). In addition, we only observed a gain in performance after errors in a specific trial type, suggesting that post-error adjustments depend on a complex combination of processes that affect the speed of ensuing actions as well as the degree to which such PES comes with a gain in performance.

This paper presents a theory of the syntactic aspects of human sentence production. An important characteristic of unprepared speech is that overt pronunciation of a sentence can be initiated before the speaker has completely worked out the meaning content he or she is going to express in that sentence. Apparently, the speaker is able to build up a syntactically coherent utterance out of a series of syntactic fragments each rendering a new part of the meaning content. This incremental, left‐to‐right mode (...) of sentence production is the central capability of the proposed Incremental Procedural Grammar (IPG). Certain other properties of spontaneous speech, as derivable from speech errors, hesitations, self‐repairs, and language pathology, are accounted for as well.The psychological plausibility thus gained by the grammar appears compatible with a satisfactory level of linguistic plausibility in that sentences receive structural descriptions which are in line with current theories of grammar. More importantly, an explanation for the existence of configurational conditions on transformations and other linguistics rules is proposed.The basic design feature of IPG which gives rise to these psychologically and linguistically desirable properties, is the “Procedures + Stack” concept. Sentences are built not by a central constructing agency which overlooks the whole process but by a team of syntactic procedures (modules) which work—in parallel—on small parts of the sentence, have only a limited overview, and whose sole communication channel is a stack.IPG covers object complement constructions, interrogatives, and word order in main and subordinate clauses. It handles unbounded dependencies, crossserial dependencies and coordination phenomena such as gapping and conjunction reduction. It is also capable of generating self‐repairs and elliptical answers to questions. IPG has been implemented as an incremental Dutch sentence generator written in LISP. (shrink)

We present a Kripke model for Girard's Linear Logic (without exponentials) in a conservative fashion where the logical functors beyond the basic lattice operations may be added one by one without recourse to such things as negation. You can either have some logical functors or not as you choose. Commutatively and associatively are isolated in such a way that the base Kripke model is a model for noncommutative, nonassociative Linear Logic. We also extend the logic by adding a coimplication operator, (...) similar to Curry's subtraction operator, which is resituated with Linear Logic's contensor product. And we can add contraction to get nondistributive Relevance Logic. The model rests heavily on Urquhart's representation of nondistributive lattices and also on Dunn's Gaggle Theory. Indeed, the paper may be viewed as an investigation into nondistributive Gaggle Theory restricted to binary operations. The valuations on the Kripke model are three valued: true, false, and indifferent. The lattice representation theorem of Urquhart has the nice feature of yielding Priestley's representation theorem for distributive lattices if the original lattice happens to be distributive. Hence the representation is consistent with Stone's representation of distributive and Boolean lattices, and our semantics is consistent with the Lemmon-Scott representation of modal algebras and the Routley-Meyer semantics for Relevance Logic.

(1) What may be gained by applying concepts generalised from economics to methodological problems? The perspective of cost-benefit analysis ('CBA' for short) may help the researcher to see what sorts of questions he should take into account when dealing with particular methodological problems. This claim is supported by applying generalised CBA-thinking to two standard problems of methodology. (2) In the practice of research the handling of basic statements does not normally constitute any problem, and no conscious decision is involved. In (...) the methodological reconstruction the key questions are: 'How can a particular basic statement be criticised?' and 'What are the costs of defending a statement that is "problematic"?' The problem of the empirical 'base' is an investment problem: whether or not to invest time and effort into processing a particular basic statement into a falsifying hypothesis for the theory we wish to test. The valuation of the costs of rejecting or, as the case may be, of defending a basic statement, are objective. (3) With respect to theories, in basic science, the issue is not one of acceptance or rejection of a single theory, but rather of theory preference. Both the rational response to a falsification and rational theory preference are governed by CBA-considerations. The option for one of two competing theories is based upon a CBA where the valuation of benefits and costs is objective. Theory change is an objective process, at least in those fields, where theorising is closely controlled by empirical testing: the better theory drives out the less good theory. The costs of defending a theory that is less good than its competitor are mainly epistemic resources forgone. The use of CBA in methodology not only is compatible with Popper's position, but it may pay to view Popper's methodology as an application of CBA to epistemic situations. (shrink)

This paper notes the apparent ineffectiveness of the critical response to competence-based education and training (CBET) and suggests that this results from a failure to correctly isolate CBET's unique, identifying features. It is argued that the prevailing tendency to identify CBET with ‘competence’ is fundamentally mistaken and that the competence approach is more properly characterised in terms of its philosophically naïve methodological strategy. It is suggested that this strategy is based upon untenable assumptions relating to the semantic status of statements (...) of outcome and the epistemological and ontological constructs to which such statements are intended to correspond.

Aristotle's _Nicomachean Ethics_ is one of the most important texts in western philosophy, and arguably the most influential text on contemporary moral theory. This _GuideBook_ introduces and assesses: * Aristotle's life and the background to the _Nicomachean Ethics_ * The ideas and text of the _Nicomachean Ethics_ * Aristotle's central role in philosophy and his continuing contribution to our ethical thought.

Hawking particles emitted by a black hole are usually found to have thermal spectra, if not exactly, then by a very good approximation. Here, we argue differently. It was discovered that spherical partial waves of in-going and out-going matter can be described by unitary evolution operators independently, which allows for studies of space-time properties that were not possible before. Unitarity dictates space-time, as seen by a distant observer, to be topologically non-trivial. Consequently, Hawking particles are only locally thermal, but globally (...) not: we explain why Hawking particles emerging from one hemisphere of a black hole must be 100 % entangled with the Hawking particles emerging from the other hemisphere. This produces exclusively pure quantum states evolving in a unitary manner, and removes the interior region for the outside observer, while it still completely agrees locally with the laws of general relativity. Unitarity is a starting point; no other assumptions are made. Region I and the diametrically opposite region II of the Penrose diagram represent antipodal points in a PT or CPT relation, as was suggested before. On the horizon itself, antipodal points are identified. A candidate instanton is proposed to describe the formation and evaporation of virtual black holes of the type described here. (shrink)

We generalize the concept of a cooperative non-transferable utility game by introducing a socially structured game. In a socially structured game every coalition of players can organize themselves according to one or more internal organizations to generate payoffs. Each admissible internal organization on a coalition yields a set of payoffs attainable by the members of this coalition. The strengths of the players within an internal organization depend on the structure of the internal organization and are represented by an exogenously given (...) power vector. More powerful players have the power to take away payoffs of the less powerful players as long as those latter players are not able to guarantee their payoffs by forming a different internal organization within some coalition in which they have more power.We introduce the socially stable core as a solution concept that contains those payoffs that are both stable in an economic sense, i.e., belong to the core of the underlying cooperative game, and stable in a social sense, i.e., payoffs are sustained by a collection of internal organizations of coalitions for which power is distributed over all players in a balanced way. The socially stable core is a subset and therefore a refinement of the core. We show by means of examples that in many cases the socially stable core is a very small subset of the core.We will state conditions for which the socially stable core is non-empty. In order to derive this result, we formulate a new intersection theorem that generalizes the KKMS intersection theorem. We also discuss the relationship between social stability and the wellknown concept of balancedness for NTU-games, a sufficient condition for non-emptiness of the core. In particular we give an example of a socially structured game that satisfies social stability and therefore has a non-empty core, but whose induced NTU-game does not satisfy balancedness in the general sense of Billera.

Among modern scholars of ancient Greek it is almost universally accepted that the historical present is only used for events and not for states and activities. A survey of the extant complete tragedies shows that this view is untenable: there are passages where static verbs like κεῖμαι ‘lie’ and εὕδω ‘sleep’ are used in the historical present and where the historical present describes a state or activity which is extended in time. On the one hand this shows that punctuality or (...) decisiveness cannot be regarded as the basic function of the historical present; on the other it leads to new interpretations of a number of passages in Greek tragedy.

It is possible to predict future life forms? In this paper it is argued that the answer to this question may well be positive. As a basis for predictions a rationale is used that is derived from historical data, e.g. from a hierarchical classification that ranks all building block systems, that have evolved so far. This classification is based on specific emergent properties that allow stepwise transitions, from low level building blocks to higher level ones. This paper shows how this (...) hierarchy can be used for predicting future life forms.The extrapolations suggest several future neural network organisms. Major aspects of the structures of these organisms are predicted. The results can be considered of fundamental importance for several reasons. Firstly, assuming that the operator hierarchy is a proper basis for predictions, the result yields insight into the structure of future organisms. Secondly, the predictions are not extrapolations of presently observed trends, but are fully integrated with all historical system transitions in evolution. Thirdly, the extrapolations suggest the structures of intelligences that, one day, will possess more powerful brains than human beings.This study ends with a discussion of possibilities for falsification of the present theory, the implications of the present predictions in relation to recent developments in artificial intelligence and the philosophical implications of the role of humanity in evolution with regard to the creation of future neural network organisms.

O. The idea of scientific progress in contemporary philosophy of science. Explicating the concept of cognitive progress means at the same time articulating an ideal of science. A desirable ideal: explain a lot and offer certainty. 1. Working out the ideal with the "foundationalist-positivist" approach. If the question, "When is it rational to accept a theory?" is answered, "When it has sufficient inductive support," this leads to insoluble problems. Reactions to the collapse of this approach - especially relativism and theory (...) instrumentalism. 2. The Popperian alternative: rational theory preference despite fallibility of methods for determining truth or greater accuracy of representations. What good reasons can there be for the conjecture that one theory is superior to a competing theory in its achievement as a description? Achievements to date as fallible but objective indicators of strength in describing. The sorts of risks for a theory differ in explanation and in prediction. Corresponding to the risks are the chances for cognitive progress. Instead of a cumulative index, itemized indication of success and failure in explanation and prediction with regard for importance of the questions at issue. On the concept of the "scientific importance" of questions. Postscript: On the political consequences of the sceptical position in philosophy of science. (shrink)

In his many and varied writings, St Thomas presents us with both a sophisticated account of human action and a complicated moral theory. In this article, I shall be considering the question of whether St Thomas’s theory of action and his moral theory are mutually consistent. My claim shall be that St Thomas can preserve the ontological unity of human action—but only at the cost of rendering it extremely difficult to evaluate in a manner consistent with his moral theory, or, (...) alternatively, that he can provide a viable ethical analysis of human action—but only at the cost of compromising its ontological unity. In the first section of this article I shall examine St Thomas’s account of a particular kind of moral action, namely lying. Two basic questions concerning the specificity of unicity of human action will emerge from this examination: 1) what makes an act to be a specific moral act?, and 2) what makes a specific moral act to be one act? In the second section of the article I shall attempt to show, by means of a textual examination, that St Thomas does not appear to be able to provide an account of human action that will satisfactorily answer both these basic questions at the same time.

In “Rothbard as a philosopher” Edward Feser harshly criticises the philosophical abilities of Murray Rothbard. According to Feser, Rothbard seems unable to produce arguments that don’t commit obvious fallacies or produces arguments that fail to address certain obvious objections. His criticism centres on what he regards as Rothbard’s principal argument for the thesis of self-ownership. In this paper, I attempt to show that Feser’s criticism fails of its purpose and that Rothbard is very far from being the epitome of philosophical (...) ineptitude that Feser takes him to be.

When examined in terms of hermeneutical principles, the revised lectionaries turn out to be distinct improvements. But it is precisely the hermeneutical function of a lectionary that raises the most important questions about the newer ones and calls for a continuing effort to bring them in line with the intention of the whole of Scripture and the principles of interpretation appropriate to it.

Until recently, Australia had little installed wind capacity, although there had been many investigations into its potential during the preceding decades. Formerly, state-owned monopoly utilities showed only token interest in wind power and could dictate the terms of energy debates. This situation changed in the late 1990s: Installed wind capacity began growing rapidly following the introduction of supportive renewable energy policies and the restructuring of the electricity industry. However, wind farms still provide only 1% of Australia's electricity, the future of (...) supportive policies is uncertain, and industry momentum is yet to become self-sustaining. Wind power, the authors argue, faces significant technological and institutional barriers, which need to be overcome if wind power is to play a significant role in Australia's electricity supply. The current window of opportunity is providing—for the first time—a significant space in which these barriers can be better understood and addressed and the requirements for wind power institutionally embedded.

The state members of the European Union have witnessed the emergence of equality policies which target discrimination on the grounds of sexual orientation and gender identity. These are usually based on the single issue model focusing exclusively on discrimination suffered by LGBT people, however there are other approaches to this issue which take into account the interaction of different axes of inequality, namely, the multiple and intersectional discrimination models. This article analyses the implications of these three models from a theoretical (...) and empirical perspective, pointing out their respective advantages and disadvantages. (shrink)

"Desartización", es el término acuñado por T.W. Adorno a fines de los años 50 para referirse al proceso dialéctico por el que el arte va perdiendo progresivamente sus cualidades y rasgos tradicionales -la autonomía que mantuvo desde Diderot a Kant, Schiller y Hegel- para convertirse en otra cosa: en producto de la industria cultural, en víctima de las fuerzas ideológicas que dominan la sociedad administrada y en mera mercancía, es decir, en un producto cosificado que deja de ser un modo (...) esencial de pensar el mundo. El autor entiende el "arte sin fin" como arte sin finalidad, objeto o función, en oposición a las doctrinas ilustradas y románticas, e intenta dar una explicación de la lógica conceptual que rige su planteamiento y su conexión con la evolución cultural.

In Epictetus 3. 23. 33 the original reading of the codex unicus Bodleianus Auct. T. 4. 13, ἐκλεκτικός, is certainly corrupt. All the editions accept the reading ἐλεγκτικός, which is a correction by a later corrector of Bodleianus Auct. T. 4. 13. It is shown that this reading is to be rejected because ἐλεγκτικός is equivalent to the immediately preceding προτρεπτικός and because it leads to unsurmountable discrepancies with the closely related passage 3. 21. 19. As an alternative for ἐλεγκτικός, (...) the emendation ἐπιπληκτικός is proposed: with this reading all problems disappear. The new reading has important consequences for the evaluation of Epictetus’ educational system. (shrink)

Summary Research consists of choosing a problem, proposing and testing problem solutions, and presenting the results. In its central moment — conjectures and testing — science must be autonomous in order to be successful. Securing this autonomy by organizational means is one of the tasks of research policy. Research needs to justify itself only when the researcher makes a claim to the resources of others. To discuss problems of justification of governmental support, it is imperative to distinguish between basic and (...) applied research. In basic research the problem choice is guided only by considerations of scientific interest , while in applied research the problems emanate from extra-scientific concerns since applied research is by definition a means for tackling concrete practical problems. Deciding on external criteria (e.g. deciding whether to support more energy research or more cancer research) is a genuine political problem rather than a problem of research policy. Thus applied research can be justified by referring to the benefit the expected results will yield, but basic research requires a completely different justification. One such justification is the argument that applied research requires a certain overhead in basic research. Securing an adequate balance between funding basic and applied research within the problem area concerned is another task of research policy. (E.g. in the area of cancer whether to support more molecular biology research or more clinical research.) When the overhead argument is not applicable, there still remain several possible justifications for basic research. These are examined in the paper. When setting priorities for basic research within a certain discipline, one apparently must turn to the scientific community itself. It may well be that the researches, who constitute the only expertise available for this task, have to rely on tacit knowledge . If so, this remains afaute de mieux procedure since articulated criteria would be preferable to intuitive procedures. The purpose of methodological reflection on research policy making is to supply intellectual instruments for making the discussion about substantive problems more rational. The substantive problems can be tackled only through the close cooperation of research policy makers and researchers. Thus methodology should not limit the degrees of freedom of either but increase them. (shrink)
