Nanoscience has enabled the understanding of organisation of the atomic and molecular world. Due to the unique chemical, electronic and magnetic properties nanomaterials have wide applications in the chemical, manufacturing, medical sector etc., Single walled carbon nanotubes, buckyballs, ZnSe quantum dots, TiO 2 nanoparticle based products are nearing commercialisation. Research is on-going worldwide on suitable delivery systems for nanomaterial based drugs. Nanomaterials are highly reactive in biological systems due to the large surface area. While the benefits of nanomaterials are evident (...) there are studies which indicate the potential risk to biological systems. Substances known to be harmless in bulk can be potentially toxic in certain fibrous and nanoparticle form. Risk assessment studies with nanomaterials largely focus on mouse models. There are very few studies on their effects on aquatic species and plants which form the largest in the productivity chain with respect to the ecological pyramid. This study reviews the research done worldwide in the area of risk assessment of nanomaterials, particularly the effects on aquatic and plant systems. Risk assessment is the foundation for regulatory decision making. A general comparison of the regulatory regime in nanotechnology is performed to understand the extent of development. (shrink)

In this paper, I offer an inferential conception of computer simulations, emphasizing the role that simulations play as inferential devices to represent empirical phenomena. Three steps are involved in a simulation: an immersion step, a derivation step, and an interpretation and correction step. After presenting the view, I mention some cases, such as simulations of the current flow between silicon atoms and buckyballs as well as of genetic regulatory systems. I argue that the inferential conception accommodates the integration of empirical (...) and theoretical data; it makes sense of the role that is played by false traits in a simulation, andhighlights the similarities and differences between simulations and scientific instruments.

We note in Section I that an acceptable formulation of Presentism must preserve its consistency with Transient Time and inconsistency with Static Time. After arguing in Section II that certain formulations of Presentism are unacceptable, we offer in Section III a formulation of Presentism that we defend against the charge of triviality.

Broadly speaking, ancient concepts of causality in terms of explanatory priority have been contrasted with modern discussions of causality concerned with agents or events sufficient to produce effects. As Richard Taylor claimed in the 1967 Encyclopedia of Philosophy, of the four causes considered by Aristotle, all but the notion of efficient cause is now archaic. What we will consider here is a notion even less familiar than Aristotelian material, formal, and final causes—what we will call 'demonstrational causality'. Demonstrational causality refers (...) to the dependence of the conclusion on the premises of a demonstration. Here, if ever, we have a case of explanational priority, since among other things what is required of the premises is that they be better known or more manifest than the conclusion. But, oddly enough, Aristotle and his medieval commentators describe demonstrational causality in the same terms as efficient causality. Aristotle speaks of the conclusion as an "effect" of the premises; his commentators speak of the "sufficiency" of first principles or axioms in producing the conclusion. (shrink)

The purpose of this article is to investigate how sex segregation, social class, and gender are analytically related to occupational stratification. Recent discussions of women and men in the labor force revolve around whether a sex-segregated model in which sex of the worker affects placement, a pure social class model using classical criteria, or a gendered social class model in which social organizational processes of a gendered social class structure affect positioning in the stratification system. This article addresses the influence (...) that social class and gender have on stratification in the labor market. Data from the 1972-82 General Social Survey on 371 occupations, representing 7,541 male and female workers, are used to formulate a social class scheme based on all workers' characteristics. In comparing the models, the analyses show that an integrated gendered social class perspective is consistent with the empirical differentiation found among women and men in the labor force.

Despite popular representations to the contrary, creative people are rarely insane. But creativity and madness may be connected in other ways; we find suggestions of schizotypy in the biographies of many artists, and schizophrenia and related conditions seem to be disproportionately represented in talented and creative families. There are attractions, therefore, in the idea that creativity depends on the controlled deployment of capacities that are uncontrolled in psychosis: an idea explored by psychoanalytically inclined writers such as Ernst Kris and Hanna (...)

Duality in Logic and Language [draft--do not cite this article] Duality phenomena occur in nearly all mathematically formalized disciplines, such as algebra, geometry, logic and natural language semantics. However, many of these disciplines use the term ‘duality’ in vastly different senses, and while some of these senses are intimately connected to each other, others seem to be entirely … Continue reading Duality in Logic and Language →.

Sidgwick's seminal textThe Methods of Ethicsleft off with an unresolved problem that Sidgwick referred to as the dualism of practical reason. The problem is that employing Sidgwick's methodology of rational intuitionism appears to show that there are reasons to favour both egoism and utilitarianism. Katarzyna de Lazari-Radek and Peter Singer offer a solution in the form of an evolutionary debunking argument: the appeal of egoism is explainable in terms of evolutionary theory. I argue that like rational prudence, rational benevolence is (...) subject to debunking arguments and so problematic, but also – and more importantly – that debunking arguments are irrelevant in the debate over the dualism of practical reason on the view of reason and rational intuitionism that Lazari-Radek and Singer embrace. Either both egoism and utilitarianism are debunked, or neither are. If I am right, Sidgwick's dualism is left standing. (shrink)

This article provides a retrospective, current and prospective overview on developments in brain research and neuroscience. Both theoretical and empirical studies are considered, with emphasis in the concept of multivariability and metastability in the brain. In this new view on the human brain, the potential multivariability of the neuronal networks appears to be far from continuous in time, but confined by the dynamics of short-term local and global metastable brain states. The article closes by suggesting some of the implications of (...) this view in future multidisciplinary brain research. (shrink)

It would be very desirable to have an account of the relation between mind and world that sustained the integrity of each. In this paper, we will argue that a theory of cognition which is broadly Thomistic can do just that. Many commentators recognize that cognitio is Aquinas’s basic epistemic concept, and that it designates knowledge in the broadest and most basic sense, as distinguished from scientia, or knowledge in the paradigmatic sense. There are several important consequences of this distinction (...) which are relevant to a proper understanding of the way in which a theory of knowledge which is in the Aristotelian-Thomistic tradition approaches the issue of the relation between the mind and the world. First and foremost, knowledge cannot be construed as a univocal concept in the A/t context. There are different senses of knowledge and we should not expect there to be a theory which supplies necessary and sufficient conditions for “S knows that p” that satisfies all the different senses of knowledge. It is perplexing that the contemporary discussion seems to miss this point, for the same sort of systematic ambiguity of the term ‘knowledge’ seems to hold in English. Second, the A/t theory of knowledge is not an epistemological theory in the modern sense, if by “epistemological” we mean one which is clearly demarcated from a metaphysical, psychological, or even semantical theory. The A/t theory is a metaphysics of knowledge. Third, a Thomistic theory of knowledge begins with a theory of cognition which provides the grounds of knowledge across the board, including even that of scientia. (shrink)

This grounded study investigated the negotiation of authorship by faculty members, graduate student mentors, and their undergraduate protégés in undergraduate research experiences at a private research university in the northeastern United States. Semi-structured interviews using complementary scripts were conducted separately with 42 participants over a 3 year period to probe their knowledge and understanding of responsible authorship and publication practices and learn how faculty and students entered into authorship decision-making intended to lead to the publication of peer-reviewed technical papers. Herein (...) the theoretical model for the negotiation of authorship developed through the analysis of these interviews is reported. The model identifies critical causal and intervening conditions responsible for the coping strategies faculty and students employ, which, in our study, appear to often produce unfortunate consequences for all involved. The undergraduate student researchers and their graduate student mentors interviewed in this study exhibited a limited understanding of authorship and the requirements for authorship in their research groups. The power differential between faculty and students, the students’ limited epistemic development, the busy-ness of the faculty, and the faculty’s failure to prioritize authorship have been identified as key factors inhibiting both undergraduate and graduate students from developing a deeper understanding of responsible authorship and publication practices. Implications for graduate education and undergraduate research are discussed, and strategies for helping all students to develop a deeper understanding of authorship are identified. (shrink)

More and more these days it is asked whether aesthetics is still possible. A question that, given the context and phrasing, seems to direct us towards its answer. Conferences and meetings, books and journal specials examine the issue of aesthetics, talk about rediscovery or return of aesthetics. Well known philosophers and aestheticians underscore the need to reconsider the foundations of aesthetics and set new directions for aesthetics today (Berleant, 2004) or attempt to expand aesthetics beyond aesthetics–like Welsch, for example who (...) tries to extend aesthetics beyond art to society and the life-world (Welsch, 1997). Others underline the need to revisit the aesthetic experience (Shusterman, 1999; Iseminger, 2002, Fenner, 1996) and examine the relevance or irrelevance of the aesthetic with art (Carroll, 2001). It seems that it is strongly recommended to turn to aesthetics on the condition however to carefully re-approach the meaning and import of the term in the present situation. The aesthetic that Passmore condemned as “dreary”(Passmore, 1954), the one Sparshott considered a formless conception, vague and loose in application (Sparshott, 1982), the same that Danto emphatically argues that has nothing to do with the definition of art or arts in general (Danto, 1981) returns to claim its rightful place in the fields of philosophy and critical theory (Levine, 1994, Michaud, 1999), as well as artistic creation. And one cannot but wonder: what does this return mean? What was the degree of aesthetics decline that we need to discuss about recovery or for new implementations of aesthetics? (shrink)

Cultural evolution, the propagation and transfer of ideas from generation to generation, as well as from one person to another and from one culture to another, is much faster than normal, genetic evolution. This could account for the speedy proliferation of humankind on this planet, at the expense of other life forms.

A response-dependent concept is a concept defined via reference to the psychological responses of suitably situated subjects. For example, something is red, according to the response-dependent account of that concept, if and only if it would look red to suitable subjects under suitable conditions; something is uncomfortable, according to the response-dependent account of that concept, if and only if it causes the discomfort of suitable subjects in suitable conditions; and so we might go on.

THE CENTRALITY OF "SYMPATHY" to Adam Smith's Theory of Moral Sentiments points to the centrality of love in the book. While Smith delineates a somewhat unusual, technical sense of "sympathy", his actual use of the term frequently slips into its more ordinary sense of "compassion" or affectionate fellow feeling. This no doubt intentional equivocation on Smith's part helps suffuse the book with these themes, to the point that, without much exaggeration, one could say that the Theory of Moral Sentiments is (...) generally about love: our need for love and sympathy, love as friendship, self-love, the love of praise and praiseworthiness, the love of beauty. Even in the Wealth of Nations, our loves are thought to be very important in explaining our behavior. Smith is unusual among modern moral philosophers in according so central a place to love in this broad sense, although of course Christianity made love a central theme in reflection on ethical life, and philosophers such as Hutcheson made benevolence a key virtue in their ethical systems. However, it is not our purpose to examine Smith's critique of Hutcheson or indeed of any of his predecessors. Rather we aim in this paper to reflect on his treatment of this topic. We shall do so in part by means of comparisons with Aristotle and Plato, first with respect to friendship and then with respect to love generally. Smith's writing is replete with classical references, raising the issue of the degree to which his thought is "ancient" or "modern." Friendship is arguably the pinnacle of social relations for the ancients, and thus it provides us with a useful device for determining the degree to which Smith's thought embodies classical moral and philosophical principles. The subtlety of Smith's interweaving of traditions will become visible as we reflect not just on the ways Smith's thought exhibits classical conceptions of friendship and love, but also on the ways he departs from them. For in at least one important respect, love is a closed book from Smith's standpoint, and thus, as it turns out, also at odds with classical friendship. (shrink)

A MAJOR THESIS OF CONTEMPORARY LIBERAL PHILOSOPHY is that its theory of justice, which incorporates strong rights to negative liberty, must be prior to and independent of a theory of the good. This priority is necessary, according to liberal theorists, in view of the requirement that any adequate theory accommodate a plurality of contending views of the good, no one of which is capable of eliciting public assent to it. Recent critics of liberalism have disputed this thesis, maintaining instead that (...) there is indeed an objective good, rather than a plurality of contending goods, which at least seriously compromises and possibly undermines the negative liberty with which liberals traditionally associated their theories. Variously called communitarians, virtue theorists, or republicans, these critics have presented an important challenge to contemporary liberalism whether of the individualist or welfare state variety.

Rousseau is considered to be at once the most modern political thinker of the 18th century and the most ancient in his allegiance to classical republicanism. These essays address the place of liberty in his moral and political philosophy, and the origins, meaning, strength, weakness and significance of his argument.

Epistemologists and philosophers of science have often attempted to express formally the impact of a piece of evidence on the credibility of a hypothesis. In this paper we will focus on the Bayesian approach to evidential support. We will propose a new formal treatment of the notion of degree of confirmation and we will argue that it overcomes some limitations of the currently available approaches on two grounds: (i) a theoretical analysis of the confirmation relation seen as an extension of (...) logical deduction and (ii) an empirical comparison of competing measures in an experimental inquiry concerning inductive reasoning in a probabilistic setting.

Contemporary psychiatry faces serious challenges because it has failed to incorporate accumulated knowledge from basic neuroscience, neurophilosophy, and brain–mind relation studies. As a consequence, it has limited explanatory power, and effective treatment options are hard to come by. A new conceptual framework for understanding mental health based on underlying neurobiological spatial-temporal mechanisms of mental disorders (already gained by the experimental studies) is beginning to emerge.

We focus attention on the “resilience” property of republican liberty —a property that, at least in some formulations, is among those features that distinguish republican liberty from its more familiar “liberal” counterpart. Our analysis suggests, and builds on, an analogy between resilience and risk aversion. After a brief description of what we take republican liberty to be, we turn to the question of how to conceptualise resilience and how the notion might most plausibly be formulated. Examining alternative possible formulations serves (...) to suggest the analogy between resilience and risk aversion. In Section III, we exploit that analogy to develop some implications that resilience carries for republican institutional design. Section IV offers a brief summary. (shrink)

Should we make people healthier, smarter, and longer-lived if genetic and medical advances enable us to do so? Matti Häyry asks this question in the context of genetic testing and selection, cloning and stem cell research, gene therapies and enhancements. The ethical questions explored include parental responsibility, the use of people as means, the role of hope and fear in risk assessment, and the dignity and meaning of life. Taking as a starting point the arguments presented by Jonathan Glover, John (...) Harris, Ronald M. Green, Jürgen Habermas, Michael J. Sandel, and Leon R. Kass, who defend a particular normative view as the only rational or moral answer, Matti Häyry argues that many coherent rationalities and moralities exist in the field, and that to claim otherwise is mistaken"--Provided by publisher.

Not only did he found his own school of philosophy, known as eclecticism, but he reintroduced into French intellectual life the study and appreciation of the history of philosophy, and produced studies and translations--of Plato and Proclus, Descartes and Pascal--that stand to this day as paradigms of exegetical thoroughness. And it was he who first pointed out to his countrymen that there was some serious philosophical work being carried out on the other side of the Rhine.

A Dialogue on Foucault and the Psychological Sciences.

This research explores temporal concept drift and temporal alignment in knowledge organization systems. A comparative analysis is pursued using the 1910 Library of Congress Subject Headings, 2020 FAST Topical, and automatic indexing. The use case involves a sample of 90 nineteenth-century Encyclopedia Britannica entries. The entries were indexed using two approaches: 1) full-text indexing; 2) Named Entity Recognition was performed upon the entries with Stanza, Stanford’s NLP toolkit, and entities were automatically indexed with the Helping Interdisciplinary Vocabulary application, using both (...) 1910 LCSH and FAST Topical. The analysis focused on three goals: 1) identifying results that were exclusive to the 1910 LCSH output; 2) identifying terms in the exclusive set that have been deprecated from the contemporary LCSH, demonstrating temporal concept drift; and 3) exploring the historical significance of these deprecated terms. Results confirm that historical vocabularies can be used to generate anachronistic subject headings representing conceptual drift across time in KOS and historical resources. A methodological contribution is made demonstrating how to study changes in KOS over time and improve the contextualization historical humanities resources. (shrink)

Consider a recent expression of such traditionalism.

That space and time should be integrated into a single entity, spacetime, is the great insight of Einstein's special theory of relativity, and leads us to regard spacetime as a fundamental context in which to make sense of the world around us. But it is not the only one. Causality is equally important and at least as far as the special theory goes, it cannot be subsumed under a fundamentally geometrical form of explanation. In fact, the agent of propagation of (...) causal influence is electromagnetic radiation. In this examination, the authors find support for a rationalist approach to physics, never neglecting experimentation, but rejecting a simple empiricist or positivist view of science. (shrink)
