Recent work in the strategic-relational approach to explaining the relationship between structure and agency emphasises the significance of ideas, discourses, and the semiotic realm of symbols. However, this work does not yet offer an explanation of how discourses relate to symbols – how texts take on meaning. This article shows why this is needed. It then provides such an account of language use and learning in explicitly strategic-relational terms. That account both grounds strategic-relational concepts of discourse, and helps define them (...) more clearly. While complementing and strengthening such notions, it also provides an insight into the way particular discourses interrelate. In particular, the model presented here suggests the importance of the constructive and critical potential of reason, in enlarging the scope for critical syntheses across discourses, and guarding against hegemony.

Much of the appeal of deliberative democracy lies in its emancipatory promise to give otherwise disadvantaged groups a voice, and to grant them influence through reasoned argument. However, the precise mechanisms for delivery of this promise remain obscure. After reviewing Habermas's formulation of deliberation, the article draws on recent theories of argumentation to provide a more detailed account of such mechanisms. The article identifies the key emancipatory mechanism as explicitness in language. It outlines the primary modalities of this mechanism: expressing (...) differences of opinion, mobilising a shared standard of inference, and recognising and excluding fallacious appeals to irrelevant factors such as force or authority. It describes how these modalities are enhanced at a secondary, reflexive level that recognises the partiality and defeasibility of particular argumentative exchanges. Such qualifications, it is argued, support a model of deliberation across discourses that allows a clearer appreciation of its potential and limits. (shrink)

This paper examines the properties of the validity and scope of arguments as standards for evaluating the epistemic qualities of particular deliberative exchanges within a context of value pluralism where parties can hold differing views of the common good based on incommensurable basic values. In this context, the task of political decisions is to maximise the interests of all, only judging between internally coherent versions of the common good on the basis of their mutual impact. The paper argues open, democratic, (...) deliberation provides the best chance of discovering such a path, through developing mutual understanding across incommensurable positions. Identifying the validity and scope of a deliberative exchange enhances this potential. Any deliberative exchange may be characterised in terms of its validity – the reasons that support its conclusions – and scope – the unquestioned assumptions that mark the boundaries of that reasoning. The paper explains the epistemic role of these two features in developing understanding across plural positions. Clarity about the validity of an exchange reveals positions that can be shared. Acknowledgement of its scope avoids over-extending its conclusions and reveals how positions differ, providing the starting point for further deliberation about their co-ordination. The paper ends by drawing the conclusion that deliberation characterised in this way should be democratic and open. (shrink)

The term ‘breeding system’ is used to describe the morphological and behavioural aspects of the sexual life cycle of a species. The yeast breeding system provides three alternatives that enable hapoids to return to the diploid state that is necessary for meiosis: mating of unrelated haploids (amphimixis), mating between spores from the same tetrad (intratetrad mating, automixis) and mother daughter mating upon mating type switching (haplo‐selfing). The frequency of specific mating events affects the level of heterozygosity present in individuals and (...) the genetic diversity of populations. This review discuses the reproductive strategies of yeasts, in particular S. cerevisiae (Bakers' or budding yeast). Emphasis is put on intratetrad mating, its implication for diversity, and how the particular genome structure could have evolved to ensure the preservation of a high degree of heterozygosity in conjunction with frequent intratetrad matings. I also discuss how the ability of yeast to control the number of spores that are formed accounts for high intratetrad mating rates and for enhanced transmission of genomic variation. I extend the discussion to natural genetic variation and propose that a high level of plasticity is inherent in the yeast breeding system, which may allow variation of the breeding behaviour in accordance with the needs imposed by the environment.

In 2004 Atserias, Kolaitis, and Vardi proposed $\text {OBDD}$ -based propositional proof systems that prove unsatisfiability of a CNF formula by deduction of an identically false $\text {OBDD}$ from $\text {OBDD}$ s representing clauses of the initial formula. All $\text {OBDD}$ s in such proofs have the same order of variables. We initiate the study of $\text {OBDD}$ based proof systems that additionally contain a rule that allows changing the order in $\text {OBDD}$ s. At first we consider a proof (...) system $\text {OBDD}$ that uses the conjunction rule and the rule that allows changing the order. We exponentially separate this proof system from $\text {OBDD}$ proof system that uses only the conjunction rule. We prove exponential lower bounds on the size of $\text {OBDD}$ refutations of Tseitin formulas and the pigeonhole principle. The first lower bound was previously unknown even for $\text {OBDD}$ proofs and the second one extends the result of Tveretina et al. from $\text {OBDD}$ to $\text {OBDD}$.In 2001 Aguirre and Vardi proposed an approach to the propositional satisfiability problem based on $\text {OBDD}$ s and symbolic quantifier elimination $ algorithms). We augment these algorithms with the operation of reordering of variables and call the new scheme $\text {OBDD}$ algorithms. We notice that there exists an $\text {OBDD}$ algorithm that solves satisfiable and unsatisfiable Tseitin formulas in polynomial time, but we show that there are formulas representing systems of linear equations over $\mathbb {F}_2$ that are hard for $\text {OBDD}$ algorithms. Our hard instances are satisfiable formulas representing systems of linear equations over $\mathbb {F}_2$ that correspond to checksum matrices of error correcting codes. (shrink)

Neural network models of memory are notorious for catastrophic interference: Old items are forgotten as new items are memorized (French, 1999; McCloskey & Cohen, 1989). While working memory (WM) in human adults shows severe capacity limitations, these capacity limitations do not reflect neural network style catastrophic interference. However, our ability to quickly apprehend the numerosity of small sets of objects (i.e., subitizing) does show catastrophic capacity limitations, and this subitizing capacity and WM might reflect a common capacity. Accordingly, computational investigations (...) (Knops, Piazza, Sengupta, Eger & Melcher, 2014; Sengupta, Surampudi & Melcher, 2014) suggest that mutual inhibition among neurons can explain both kinds of capacity limitations as well as why our ability to estimate the numerosity of larger sets is limited according to a Weber ratio signature. Based on simulations with a saliency map‐like network and mathematical proofs, we provide three results. First, mutual inhibition among neurons leads to catastrophic interference when items are presented simultaneously. The network can remember a limited number of items, but when more items are presented, the network forgets all of them. Second, if memory items are presented sequentially rather than simultaneously, the network remembers the most recent items rather than forgetting all of them. Hence, the tendency in WM tasks to sequentially attend even to simultaneously presented items might not only reflect attentional limitations, but also an adaptive strategy to avoid catastrophic interference. Third, the mean activation level in the network can be used to estimate the number of items in small sets, but it does not accurately reflect the number of items in larger sets. Rather, we suggest that the Weber ratio signature of large number discrimination emerges naturally from the interaction between the limited precision of a numeric estimation system and a multiplicative gain control mechanism.

A revision of George Kennedy's translation of, introdution to, and commentary on Aristotle's On Rhetoric. His translation is most accurate, his general introduction is the most thorough and insightful, and his brief introductions to sections of the work, along with his explanatory footnotes, are the most useful available.

The importance of the Low Countries as a centre for the study of foreign languages is well-known. The mutual relationship between the Dutch grammatical tradition and the Western European context has, however, been largely neglected. In this collection of papers on the history of linguistics in the Low Countries the editors have made an effort to present the Dutch tradition in connection with that of the neighbouring countries. Three articles by Claes, Dibbets and Klifman deal with the earliest stages of (...) the development of a grammar for the Dutch vernacular. Several important European figures worked in the Low Countries; their contribution to linguistics is discussed in articles on Vossius (Rademaker), Spinoza (Klijnsmit), and one of the most original phoneticians of European linguistics, Montanus (Hulsker). Vivian Salmon's article is a survey on the relations between English and Dutch linguistics in the field of foreign language teaching. In the 19th century Dutch linguistics had a special relationship with German general and historical linguistics; four articles deal with this period (Jongeneelen, van Driel, le Loux-Schuringa, Noordegraaf). Finally, there are three articles by Kaldewij, Hagen and van Els/Knops on the development of three branches of linguistics in the 20th century: structuralism, dialectology and applied linguistics. This volume should be of interest for all specialists in the history of linguistics in Europe, who are interested in the interdependence of the various traditions. (shrink)

Recent research on algebraic models of _quasi-Nelson logic_ has brought new attention to a number of classes of algebras which result from enriching (subreducts of) Heyting algebras with a special modal operator, known in the literature as a _nucleus_. Among these various algebraic structures, for which we employ the umbrella term _intuitionistic modal algebras_, some have been studied since at least the 1970s, usually within the framework of topology and sheaf theory. Others may seem more exotic, for their primitive operations (...) arise from algebraic terms of the intuitionistic modal language which have not been previously considered. We shall for instance investigate the variety of _weak implicative semilattices_, whose members are (non-necessarily distributive) meet semilattices endowed with a nucleus and an implication operation which is not a relative pseudo-complement but satisfies the postulates of Celani and Jansana’s strict implication. For each of these new classes of algebras we establish a representation and a topological duality which generalize the known ones for Heyting algebras enriched with a nucleus. (shrink)

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the (...) fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon and as a cultural phenomenon. Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested. (shrink)

Eco-labels emphasize information disclosure as a tool to induce environmentally friendly behaviors by both firms and consumers. The goal of eco-labels is to reduce information asymmetry between producers and consumers over the environmental attributes of a product or service. However, by focusing on this information asymmetry, rather than on how the label meets consumer needs, eco-labels may send irrelevant, confusing, or even detrimental messages to consumers. In this article, the authors investigate how the environmental signal of eco-labels interacts with product (...) characteristics such as brand, quality, and price. In a discrete choice experiment, the authors examine consumer response to two similar eco-labels for wine, one associated with a quality reduction and the other not. The results show that respondents preferred both eco-labeled wines over otherwise identical conventional counterparts when the price was lower and the wine was from a lower quality region. However, they preferred conventional, more expensive wine from a high-quality region. This preference indicates that respondents not only obtain some warm glow value from eco-labeled wine but also possibly interpret eco-labeling as a signal of lower quality. This relationship held across both types of eco-labels, meaning that consumers did not understand the difference between them. This research contributes to the literature on information disclosure policies by highlighting important elements for effective eco-labels. These elements include consumer awareness and understanding of the eco-label, and consumer willingness to pay for an eco-labeled product. The results emphasize the need to create eco-labels that communicate clearly both the environmental attributes and the private benefits associated with them. (shrink)

We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their interactions with the receptor site. But, naturally occurring smells are parsed from gaseous odor plumes. To give a comprehensive account of the nature of odors the chemosciences must account for these large distributed entities as well. We offer a focused review of (...) what is known about the perception of odor plumes for olfactory navigation and tracking, which we then connect to what is known about the role odorants play as properties of the plume in determining odor identity with respect to odor quality. We end by motivating our central claim that more research needs to be conducted on the role that odorants play within the odor plume in determining odor identity. (shrink)

Purpose. To consider the uniqueness of Descartes’ way of interpreting poetry as a type of philosophizing that makes it possible to comprehend the metaphysical nature of man. Its implementation involves the consistent solution of the following tasks: a) understanding methodological changes in the philosophy of the 20th century in the process of actualization of anthropological interest; b) argumentation of the importance of poetic thinking for early Descartes in the process of addressing modern historians of philosophy and the thinker’s texts. Theoretical (...) basis. I rely on the conceptual positions of phenomenology, existentialism and hermeneutics. Originality. Finding of the study is that poetic thinking is the most authentic way of meaningful comprehension of the metaphysicity of man. The paper outlines the nature of the expression of this correlation in the philosophizing of the 20th-21th centuries and substantiates the thesis about the importance of the poetic principle for understanding the phenomenon of man in early works by Descartes. Conclusions. The paper examined the methodological shifts in anthropologically oriented philosophizing of the 20th-21th centuries and focused on the manifestations of related moments in the philosophical legacy of Descartes. The latter demonstrates the existence of a still underestimated version of interpreting the metaphysical foundations of human existence, the form of understanding of which is poetic thinking. It is a form of caring for the humane in man. (shrink)

In this paper I examine Grace A. de Laguna’s theory of universals in its historical context and in relation to contemporary debates in analytic metaphysics. I explain the central features of her theory, arguing that her theory should be classified as a form of immanent realism and as a powers ontology. I then show in what ways her theory affords a theory of modality in terms of potentialities and discuss some of its consequences along the way.
