Previous research on the neural basis of cognitive control processes has mainly focused on cortical areas, while the role of subcortical structures in cognitive control is less clear. Models of basal ganglia function as well as clinical studies in neurodegenerative diseases suggest that the striatum (putamen and caudate nucleus) modulates the inhibition of interfering responses and thereby contributes to an important aspect of cognitive control, namely response interference control. To further investigate the putative role of the striatum in the control (...) of response interference, 23 patients with stroke-induced lesions of the striatum and 32 age-matched neurologically healthy controls performed a unimanual version of the Simon task. In the Simon task, the correspondence between stimulus location and response location is manipulated so that control over response interference can be inferred from the reaction time costs in incongruent trials. Results showed that stroke patients responded overall slower and more erroneous than controls. The difference in response times (RTs) between incongruent and congruent trials (known as the Simon effect) was smaller in the ipsilesional/-lateral hemifield, but did not differ significantly between groups. However, in contrast to controls, stroke patients exhibited an abnormally stable Simon effect across the reaction time distribution indicating a reduced efficiency of the inhibition process. Thus, in stroke patients unilateral lesions of the striatum did not significantly impair the general ability to control response interference, but led to less efficient selective inhibition of interfering responses.

ABSTRACT What constitutes a Black Swan? And under what conditions may a Black Swan be expected to arise? As Nassim Taleb describes it, a Black Swan is an event that displays three key properties, the two most important of which are that: (1) it is not even imagined as a possibility prior to its occurrence; and (2) it is in some way significant in its impact. It follows that whether or not an event counts as a Black Swan depends on (...) the subjective imaginings of contemporaneous observers and their (usually implicit) criteria regarding what counts as a “significant impact.” Since there is nothing in determinism that precludes (1) and (2), Black Swans may occur even in a perfectly deterministic world. Nevertheless, if the world is indeed characterised by randomness, free will, emergence, and the like, then it is arguably more likely to throw forth events that display the above‐mentioned properties. The same goes for various specific features of an increasingly interconnected global economy, which allowed Taleb (paradoxically) to forecast what was, for most of us at least, the great Black Swan of 2008.

I examine the abstraction/representation theory of computation put forward by Horsman et al., connecting it to the broader notion of modeling, and in particular, model-based explanation, as considered by Rosen. I argue that the ‘representational entities’ it depends on cannot themselves be computational, and that, in particular, their representational capacities cannot be realized by computational means, and must remain explanatorily opaque to them. I then propose that representation might be realized by subjective experience (qualia), through being the bearer of the (...) structure of abstract objects that are represented. (shrink)

With this special issue, we would like to promote research on changes in the funding of the sciences, social sciences, and humanities. Since funding secures the livelihood of researchers and the means to do research, it is an indispensable condition for almost all research; as funding arrangements are undergoing dramatic changes, we think it timely to renew the science studies community’s efforts to understand the funding of research. Changes in the governance of science have garnered considerable attention from science studies (...) and higher education research; however, the impact of these changes on the conduct and content of research has not received sufficient attention, and theoretical insights into the connections between funding practices and research practices are few and far between. The aim of this special issue is to contribute to our theoretical understanding of the changing nature of research funding and its impact on the production of scientific knowledge. More specifically, we are interested in the interplay between funding and research practices: What is the impact of institutionalised funding arrangements on the production of scientific knowledge?

Radbruch and Kantorowicz as a topic has been widely untouched, in spite of obvious commonalities in their lives and works. In addition, there are a number of misconceptions and misconstructions pertaining to the relationship between Radbruch and Kantorowicz in the areas of legal philosophy and legal theory. The article discusses the strong parallels and commonalities between the lives and works of Radbruch and Kantorowicz, clarifies the question of whether and to what extent relativism and trialism form a common neo-Kantianistic basis, (...) and finally investigates whether the Free Law movement served as a common methodological basis for the two scholars. The author comes to the conclusion that Radbruch and Kantorowicz share common convictions despite their distinctive differences. (shrink)

In this paper I offer an appraisal of James Bogen and James Woodward’s distinction between data and phenomena which pursues two objectives. First, I aim to clarify the notion of a scientific phenomenon. Such a clarification is required because despite its intuitive plausibility it is not exactly clear how Bogen and Woodward’s distinction has to be understood. I reject one common interpretation of the distinction, endorsed for example by James McAllister and Bruce Glymour, which identifies phenomena with patterns in data (...) sets. Furthermore, I point out that other interpretations of Bogen and Woodward’s distinction do not specify the relationship between phenomena and theories in a satisfying manner. In order to avoid this problem I propose a contextual understanding of scientific phenomena according to which phenomena are states of affairs which play specific roles in scientific practice and to which we adopt a special epistemic attitude. Second, I evaluate the epistemological significance of Bogen and Woodward’s distinction with respect to the debate between scientific realists and constructive empiricists. Contrary to what Bogen and Woodward claim, I argue that the distinction does not provide a convincing argument against constructive empiricism. (shrink)

This essay presents a phenomenological analysis of the functioning of symbols as elements of the life-world with the purpose of demonstrating the interrelationship of individual and society. On the basis of Alfred Schutz''s theory of the life-world, signs and symbols are viewed as mechanisms by means of which the individual can overcome the transcendences posed by time, space, the world of the Other, and multiple realities which confront him or her. Accordingly, the individual''s life-world divides itself into the dimensions of (...) time, space, the social world and various reality spheres which form the boundaries or transcendences that the I has to understand and integrate. Signs and symbols are described as appresentational modes which stand for experiences originating in the different spheres of the life-world within the world of everyday life, within which they can be communicated, thereby establishing intersubjectivity. Schutz''s theory of the symbol explains how social entities – such as nations, states or religious groups – are symbolically integrated to become components of the individual''s life-world. The following paper reconstructs Schutz''s concept of the symbol as a crucial component of his theory of the life-world, which is seen as an outstanding phenomenological contribution to the theory of the sign and the symbol in general.

La creatividad especialmente surge del poder de subjetivación y de trascenderse a sí mismo el ser humano. La capacidad de ser creativo resulta, desde la perspectiva de la antropología filosófica, de la “posicionalidad excéntrica” del ser humano, la cual explica su poder de reflexividad y su compulsión y necesidad de crear cultura. Según la teoría de la creatividad de orientación sociológico-antropológica de Heinrich Popitz, esta capacidad humana de desarrollar lo nuevo está basada en las formas de acción de explorar, crear, (...) generar sentido y jugar. Para explicar el poder de subjetivación del individuo, introducimos la sociología con orientación fenomenológica de Alfred Schütz, quien ofrece una teoría de las relevancias que permite analizar las motivaciones subjetivas que conducen el proceso creativo.

The present study examined what participants perceive of their hand movements when using a tool. In the experiments different gains for either the x-axis or the y-axis perturbed the relation between hand movements on a digitizer tablet and cursor movements on a display. As a consequence of the perturbation participants drew circles on the display while their covered hand movements followed either vertical or horizontal ellipses on the digitizer tablet. When asked to evaluate their hand movements, participants were extremely uncertain (...) about their trajectories. By varying the amount of visual feedback, findings indicated that the low awareness of one’s own movements originated mainly from an insufficient quality of the humans’ tactile and proprioceptive system or from an insufficient spatial reconstruction of this information in memory.

In lieu of an abstract, here is a brief excerpt of the content:"But I Don’t Feel It":Values and Emotions in the Assessment of Competence in Patients With Anorexia NervosaJochen Vollmann (bio)Keywordscompetence assessment, mental capacity, informed consent, psychiatry, anorexia nervosaThe respect of the self-determination of patients obliges physicians to obtain the patient's consent before providing medical treatment. One important condition for a valid informed consent is the patient's competence to make autonomous health care decisions. Therefore, a proper assessment of competence to (...) make health care decisions is crucial particularly in patients with mental disorders (Vollmann 2000; Helmchen and Vollmann 2001). In recent years, several empirical studies on the assessment of competence in patients suffering from different mental disorders have been performed using the MacArthur Competence Assessment Tool-Treatment (MacCAT-T; Grisso and Appelbaum1998). This assessment tool is based on legal standards of competence such as understanding, reasoning, appreciation, and expressing a choice. Since its first publication, the MacCAT-T has been widely accepted as a "gold standard" of competence assessment in the psychiatric literature. In recent years the MacCAT-T has been applied to patients suffering from depression, schizophrenia, dementia, angina pectoris, and normal controls (for overview, see Welie [2001] and Bauer and Vollmann [2002]).Tan and her colleagues (2006) use the MacCAT-T the first time to assess competence to make treatment decisions in patients with anorexia nervosa. Coming from clinical practice, the authors have noticed that the MacCAT-T might not work in this group of patients. Therefore, they use semi-structured interviews in addition to the MacCAT-T to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. They use grounded theory techniques for a qualitative analysis of the data as well as five brief, self-administered questionnaires to ascertain levels of psychopathology.The results of the study show that anorexia nervosa can have complex and variable effects on concentration, beliefs, and thought processing without affecting the ability to perform well on the MacCAT-T. At the same time, participants also report a change in their value system as well as in their personal identity. The authors argue that the results of their studies suggest that the competence to refuse treatment might be compromised in [End Page 289] people with anorexia nervosa in ways that are not captured by the MacCAT-T. This is an interesting finding in patients with anorexia nervosa, because in all other studies with patients suffering from mental disorders such as dementia, depression, and schizophrenia, the MacCAT-T identified more patients as limited in their competence to make health care decisions in comparison with other methods of competence assessment such as clinical judgment (Vollmann et al. 2003). The authors argue on the basis on their qualitative, semistructured interviews that anorexia nervosa–specific difficulties with a thought process and the change of values are missed by the MacCAT-T.Furthermore, Tan and her associated could not find a relationship between the participants' scores on the psychopathological scales, the MacCAT-T scores, and their difficulties expressed during the qualitative interviews, although the small size of the study precludes statistical analysis. In an earlier study, clinical dementia scales but not neuropsychological testing correlated with formal (MacCAT-T) and clinical assessment of competence. Therefore, psychopathological factors might play a different role in different subgroups of patients suffering from different mental problems. However, the idea of an objective neuropsychological model of competence assessment, again, finds no support in the presented empirical data.The qualitative data from patients with anorexia nervosa underline the problem of the cognitive bias of the MacCAT-T assessment and the illusion of value-free categories. It has been argued that the cognitive focus for the MacCAT-T is in itself a normative convention and that the MacCAT-T is missing the complexity of the process to make health care decisions in real life. Therefore, values and emotions should be considered in addition to cognitive functions in assessing competence to make health care decisions (Breden and Vollmann 2004; see also "Mental capacity" 2004). Although many authors agree that the cognitive approach of capacity assessment is important but not sufficient for the assessment of competence to make health care decisions, it remains an...

Urban action is ordinary action, like the old man who persists in living on the Champs-Élysées. Urban action finds itself in contradiction with urban politics, as understood by the left, which organises resistance against evictions, when it is too late. What is this city that resists? A sense of it can be given, parenthetically, between the icons of modern architecture and the informal Turkish shantytown huts of the 1950s, which inspired a whole theatre having as public the middle classes, who (...) welcomed old squatters into their midst : President Erdogan himself lived in one of these huts! But now there are new refugees arriving from other countries who do not have this peripepheral space in which to build their own lives. (shrink)

Originally created in 1892, Hugo Rheinhold’s sculpture “Monkey contemplating a human skull“ continues to attract a global audience. It is particularly appreciated by science ethicists, physical anthropologists and evolutionary biologists.This article explores the iconography of the sculpture, analyzes its iconology and discusses its message: an appeal to scientists – rendered through a witty, multilayered symbolism – to consider the ethical implications of their research. Biographical background information on the life of the German-Jewish artist and philosopher sheds further light on the (...) ethical and pacifist dimensions of his work. (shrink)

This paper gives a simple method for providing categorial brands of feature-based unification grammars with a model-theoretic semantics. The key idea is to apply the paradigm of fibred semantics (or layered logics, see Gabbay (1990)) in order to combine the two components of a feature-based grammar logic. We demonstrate the method for the augmentation of Lambek categorial grammar with Kasper/Rounds-style feature logic. These are combined by replacing (or annotating) atomic formulas of the first logic, i.e. the basic syntactic types, by (...) formulas of the second. Modelling such a combined logic is less trivial than one might expect. The direct application of the fibred semantics method where a combined atomic formula like np (num: sg & pers: 3rd) denotes those strings which have the indicated property and the categorial operators denote the usual left- and right-residuals of these string sets, does not match the intuitive, unification-based proof theory. Unification implements a global bookkeeping with respect to a proof whereas the direct fibring method restricts its view to the atoms of the grammar logic. The solution is to interpret the (embedded) feature terms as global feature constraints while maintaining the same kind of fibred structures. For this adjusted semantics, the anticipated proof system is sound and complete. (shrink)

Der Protestantismus hat ein Problem mit der Welt: Die reformatorische Behauptung eines dreifachen SOLA - Gnade, Glaube, Schrift - bricht die Kirche aus der Welt heraus, eröffnet aber neben dem schlichten Glaubensbekenntnis keine überzeugenden Kommunikationsmöglichkeiten. Wie kann nun das bürgerliche Verhältnis dieser Kirche zu der sie umgebenden Welt gedacht werden? Kann sie überhaupt in rechtlicher Gemeinschaft mit der Welt leben? Verfügt sie über geeignete Mittel, an der Gestaltung dieser Gemeinschaft mitzuwirken?Ausgehend von dem Blick auf die »Kehrseite« des SOLA - die (...) radikale Vergottlosung der Welt - und der daran notwendig sich anschließenden Zuordnung von Reformation und Neuzeit weist Jochen Bohn nach, daß der bei Luther und Calvin angelegte Bruch zwischen Kirche und Welt den Anschluß an die vermittelnde Naturrechtstradition verhindert. Des Naturrechtes als einer Brücke zur Welt entledigt, steht der Protestantismus vor dem Dilemma, sich in bürgerlichen Dingen entweder einer weltflüchtigen, oder aber einer christlich-despotischen Orientierung hingeben zu müssen. Am Beispiel Helmut Thielickes und Karl Barths zeigt Bohn, daß diese Not sich selbst in den Sozialtheorien des modernen Protestantismus äußert. Die evangelische Theologie, so die These, wird sich nur dann helfen, wird nur dann eine »gelassene Weltlichkeit« entwickeln können, wenn sie den theologischen Zustand in Fragen des Rechtes zu verlassen und in einen philosophischen Zustand einzutreten bereit ist. Bohn fordert die protestantische Theologie dazu auf, sich Philosophie als pure Weltweisheit wieder neu brauchbar zu machen. Für diese Perspektive stellt er erste theoretische Grundlagen bereit. Möglich wird die - theologisch motivierte! - Hinwendung zur Philosophie durch eine Rehabilitierung der ursprünglichen, durch Bohn jedoch deutlich korrigierten und damit neu zugänglichen Lösung des protestantischen Konfliktes mit der Welt: durch die Rückkehr zur Zwei-Reiche-Idee.

Although the computational properties of the Region Connection Calculus RCC-8 are well studied, reasoning with RCC-8 entails several representational problems. This includes the problem of representing arbitrary spatial regions in a computational framework, leading to the problem of generating a realization of a consistent set of RCC-8 constraints. A further problem is that RCC-8 performs reasoning about topological space, which does not have a particular dimension. Most applications of spatial reasoning, however, deal with two- or three-dimensional space. Therefore, a consistent (...) set of RCC-8 constraints might not be realizable within the desired dimension. In this paper we address these problems and develop a canonical model of RCC-8 which allows a simple representation of regions with respect to a set of RCC-8 constraints, and, further, enables us to generate realizations in any dimension d = 1. For three-and higher-dimensional space this can also be done for internally connected regions. (shrink)
