Synaesthesia is a condition in which one type of stimulation evokes the sensation of another, as when the hearing of a sound produces photisms, i.e. mental percepts of colours. R is a 20 year old colour blind subject who, in addition to the relatively common grapheme-colour synaesthesia, presents a rarely reported cross modal perception in which a variety of visual stimuli elicit aura-like percepts of colour. In R, photisms seem to be closely related to the affective valence of stimuli and (...) typically bring out a consistent pattern of emotional responses. The present case study suggests that colours might be an intrinsic category of the human brain. We developed an empirical methodology that allowed us to study the subject's otherwise inaccessible phenomenological experience. First, we found that R shows a Stroop effect elicited by photisms despite the fact that he does not show a regular Stroop with real colours. Secondly, by manipulating the colour context we confirmed that colours can alter R's emotional evaluation of the stimuli. Furthermore, we demonstrated that R's auras may actually lead to a partially inverted emotional spectrum where certain stimuli bring out emotional reactions opposite to the normal ones. These findings can only be accounted for by considering R's subjective colour experience or qualia. Therefore the present paper defends the view that qualia are a useful scientific concept that can be approached and studied by experimental methods. (shrink)

The Birkhoff-Maltsev problem asks for a characterization of those lattices each of which is isomorphic to the lattice L(K) of all subquasivarieties for some quasivariety K of algebraic systems. The current status of this problem, which is still open, is discussed. Various unsolved questions that are related to the Birkhoff-Maltsev problem are also considered, including ones that stem from the theory of propositional logics.

Documents as we encounter them in everyday life are complex and diverse things, whether on paper, computer disk or on the World Wide Web. They play many roles vis-à-vis human beings, and the humans engaged with them have diverse responsibilities that are not always easy to fulfil. Added to this is the issue of how a document or literary work can change and yet retain its identity, as found in maintenance, drafting and versioning of documents. This paper explores how the (...) meaning-oriented philosophy of Herman Dooyeweerd may be used to understand the complex nature of documents, to throw light on the roles, responsibilities and culture surrounding them, and to tackle issues of identity and change.

The same research proposal was submitted to 24 district health authority (DHA) research ethics committees in different parts of the country. The objective was to obtain permission for a multi-centre research project. The study of neonatal care in different types of unit (regional, subregional and district), required that four health authorities were approached in each of six widely separated health regions in England. Data were collected and compared concerning aspects of processing, including application forms, information required, timing and decision-making. The (...) key finding was that ethics committees received and processed the applications variably, reflecting individual factors and local problems. To improve consensus and facilitate multicentre studies, standard forms and instructions are suggested and the establishment of a national committee or advisory group advocated. (shrink)

This long-awaited new edition contains eight of the dialogues of Plato, and is the first in a new five-volume complete edition of his works in the OCT series.

In this paper, logics are conceived as two-sorted first-order structures, and we argue that this broad definition encompasses a wide class of logics with theoretical interest as well as interest from the point of view of applications. The language, concepts and methods of model theory can thus be used to describe the relationship between logics through morphisms of structures called transfers. This leads to a formal framework for studying several properties of abstract logics and their attributes such as consequence operator, (...) syntactical structure, and internal transformations. In particular, we treat Belief Revision Systems (BRS) as our main example, defining the Wide Belief Revision Systems (WBRS''s). This generalization allows us to define BRS''s in an abstract setting for classical and non-standard logics. We also show how the concept of translation between logics can be obtained as a particular case of transfers. (shrink)

The construct of the self is important in the domain of memory research. Recent work has shown that person memory is influenced by similarity of social targets to the self. The current experiments investigate self-similarity as defined by traits and political ideology to better understand how memory for social targets is organised. Across three experiments, participants formed positive or negative impressions based on each target’s picture, a trait-implying behavior (Experiments 1 & 2), and/or political ideology (conservative/liberal label in Experiment 2; (...) political-ideological belief statements in Experiment 3) followed by a memory test. Results showed a self-similarity effect dependent on valence in Experiment 1, but not in Experiments 2 or 3 when participants processed ideological information associated with targets. These results suggest that self-similarity has an effect on memory for social targets, but that ideological information disrupts self-focused processing of others, suggesting that ideological information also has a powerful influence on what people remember about others (i.e. social targets).

Recent work has shown that memory for various types of information associated with social targets (impressions based on behaviours and political ideology) influences decisions to approach or avoid those same targets. The current study was intended to better understand the extent that memory for other types of details associated with targets (beliefs and behaviours) affects subsequent approach/avoidance decisions. In this investigation, participants formed impressions of social targets represented by a picture and a sentence (a belief in Experiment 1; either a (...) belief or behaviour in Experiment 2). Later, memory for the impressions and sentences associated with each target was tested. Finally, participants decided whether they would want to approach or avoid each target. Results demonstrated that accurate memory strongly influenced approach/avoidance decisions for targets associated with different types of information (beliefs; behaviours), although there was no difference in the effect of memory between beliefs and behaviours. Overall, results suggest an important role of memory in decisions to approach or avoid others. (shrink)

The paper is devoted to the subject status of the discipline “Philosophy of Sociology”. Philosophy of sociology is an interdisciplinary direction focusing on the main preconditions of sociological knowledge development as well as cognitive value of sociological facts, theories and conceptions. Its subject can be divided into “philosophical foundations of sociology” and “philosophical problems of sociology”. “Sociologism” as the concept of substitution of social philosophy by sociology as a science which is better empirically oriented and is able to give more (...) exact and proved picture of social reality also poses danger to social philosophy. “Sociologism” presents a positivist attack on social philosophy. Indeed, sociology is no less speculative science than social philosophy is, which is well illustrated by a lot of divergences among its theoretical constructions and empirical data. The main functions of philosophy of sociology in the world of contemporary social-humanitarian knowledge are critical function, integrative function and axiological function. (shrink)

In this paper, we explore the role of reciprocity in the employment of restrictive measures in contexts of contagion. Reciprocity should be understood as a substantive value that governs the use, level and extent of restrictive measures. We also argue that independent of the role reciprocity plays in the legitimisation the use of restrictive measures, reciprocity can also motivate support and compliance with legitimate restrictive measures. The importance of reciprocity has implications for how restrictive measures should be undertaken when preparing (...) and evaluating public health responses to contagion. (shrink)
