The Italian Twin Registry (ITR) has been carrying out several genetic-epidemiological studies. Collection and storage of biological material from study participants has recently increased in the light of biobanking development. Within this scenario, we aimed at investigating understanding, awareness and attitude towards blood/DNA donation of research participants. About these quite unknown dimensions more knowledge is needed from ethical and social perspectives.

Theoretical and manipulative abduction conjectures and manipulations : the extra-theoretical dimension of scientific discovery. -- Non-explanatory and instrumental abduction : plausibility, implausibility, ignorance preservation. -- Semiotic brains and artificial minds : how brains make up material cognitive systems. -- Neuromultimodal abduction : pre-wired brains, embidiment, neurospaces. -- Animal abduction : from mindless organisms to srtifactual mediators. -- Abduction, affordances, and cognitive niches : sharing representations and creating chances through cognitive niche construction. -- Abduction in human and logical agents : hasty (...) generalizers, hybrid abducers, fallacies. -- Morphodynamical abduction : causation of hypotheses by attractors dynamics.

The discussion about the relationship between tone at the top and financial reporting practices has been primarily focused on the oversight role played by the board of directors and other structural elements of corporate governance. Another relevant determinant of tone at the top is the corporate narrative language, since it is a fundamental way in which the chief executive officer enacts leadership. In this study, we empirically explore the association between financial reporting aggressiveness and five thematic indicators capturing different traits (...) of ethical leadership from 535 annual letters to shareholders. We find that aggressive financial reporting is positively associated with CEO letters using a language which is resolute, complex, and not engaging. Our empirical findings highlight the importance of examining discretionary corporate narratives for the auditing process and the role of tone at the top in influencing accounting practices. (shrink)

In this study, we explore the sincerity of the rhetorical tone of 664 annual letters to shareholders (CEO letters). Prior studies adopt Impression Management theory to predict that firms obfuscate failures and emphasize successes to unfairly enhance their image and maintain organizational legitimacy. Yuthas et al. (J Bus Ethics 41:141–157, 2002) challenged such a view, showing that firms reporting earnings surprises engage in ethical discourse with shareholders. We adopt the methodology of Yuthas et al. (J Bus Ethics 41:141–157, 2002) to (...) explore the association between firm performance and the rhetorical features of CEO letters in a large sample of Fortune 500 firms in the wake of the global economic crisis. In contrast to most prior research, we find that optimistic tone is congruent with both past and future performance. We conclude that under tough macroeconomic conditions, incentives to distort public information strategically are low. Rather, firms tend to engage in communicative action aimed at dialoguing with shareholders through sincere disclosure. However, in our conclusions, we warn about the impact of accounting and rhetorical manipulation on the congruence between optimistic tone and financial performance. (shrink)

Many important concepts of the calculus are difficult to grasp, and they may appear epistemologically unjustified. For example, how does a real function appear in “small” neighborhoods of its points? How does it appear at infinity? Diagrams allow us to overcome the difficulty in constructing representations of mathematical critical situations and objects. For example, they actually reveal the behavior of a real function not “close to” a point but “in” the point. We are interested in our research in the diagrams (...) which play an optical role –microscopes and “microscopes within microscopes”, telescopes, windows, a mirror role, and an unveiling role. In this paper we describe some examples of optical diagrams as a particular kind of epistemic mediator able to perform the explanatory abductive task of providing a better understanding of the calculus, through a non-standard model of analysis. We also maintain they can be used in many other different epistemological and cognitive situations. (shrink)

What I call theoretical abduction (sentential and model-based)certainly illustrates much of what is important in abductive reasoning, especially the objective of selecting and creating a set of hypotheses that are able to dispense good (preferred) explanations of data, but fails to account for many cases of explanation occurring in science or in everyday reasoning when the exploitation of the environment is crucial. The concept of manipulative abduction is devoted to capture the role of action in many interesting situations: action provides (...) otherwise unavailable information that enables the agent to solve problems by starting and performing a suitable abductive process of generation or selection of hypotheses. Many external things, usually inert from the epistemological point of view, can be transformed into what I call epistemic mediators, which are illustrated in the last part of the paper, together with an analysis of the related notions of ``perceptual and inceptual rehearsal'' and of ``external representation''.

The academic literature in research ethics has been marked in the past decade by a much broader focus on the need for the protection of developing communities subjected to international clinical trials. Because of the proximity of the revision of the Declaration of Helsinki, completed in October 2008, most papers have addressed the issue of a double standard of care following the use of placebo. However, other no less important issues, such as interactions between the lifestyles structures of low-income communities (...) and the efficiency of risk-minimising procedures also deserve attention. The purpose of this paper is to discuss forms of uncertainty involved in clinical trials in poor and low-income countries that are not addressed by conventional methods of risk assessment. Furthermore, the increase in size of risks that are identified by conventional assessment methods will be addressed. Besides, the difficulty in properly applying risk-minimising procedures will be discussed. Finally, this paper proposes the involvement of research ethics committees in the risk evaluation process and the establishment of national ethics evaluation systems. (shrink)

Chomskyan linguistics recently seems to let its goals become wider, from a pure formal field to biology and cognitive sciences, aiming to a foretold convergence between the Universal Grammar Theory and neurosciences. In this paper I try to make the point on how far this linguistics biological trend is going today. First I’m going to talk about the foundations of biolinguistics. Then I’ll shortly face some critics against Chomsky about rationalism, innateness and modularity of mind; two theories alternative to UG (...) will be shown. Fifth and sixth paragraphs just talk about recent acquisitions on the biological foundations of language and about how the UG theory can be tested with new neuroscientific surveying techniques. The last paragraph contains some remarks on the future of biolinguistics. (shrink)

Computational philosophy (CP) aims at investigating many important concepts and problems of the philosophical and epistemological tradition in a new way by taking advantage of information-theoretic, cognitive, and artificial intelligence methodologies. I maintain that the results of computational philosophy meet the classical requirements of some Peircian pragmatic ambitions. Indeed, more than a 100 years ago, the American philosopher C.S. Peirce, when working on logical and philosophical problems, suggested the concept of pragmatism(pragmaticism, in his own words) as a logical criterion to (...) analyze what words and concepts express through their practical meaning. Many words have been spent on creative processes and reasoning, especially in the case of scientific practices. In fact, many philosophers have usually offered a number of ways of construing hypotheses generation, but they aim at demonstrating that the activity of generating hypotheses is paradoxical, obscure, and thus not analyzable. Those descriptions are often so far from Peircian pragmatic prescription and so abstract to result completely unknowable and obscure. To dismiss this tendency and gain interesting insight about the so-called logic of scientific discovery we need to build constructive procedures, which could play a role in moving the problem-solving process forward by implementing them in some actual models. The computational turn gives us a new way to understand creative processes in a strictly pragmatic sense. In fact, by exploiting artificial intelligence and cognitive science tools, computational philosophy allows us to test concepts and ideas previously conceived only in abstract terms. It is in the perspective of these actual computational models that I find the central role of abduction in the explanation of creative reasoning in science. I maintain that the computational philosophy analysis of model-based and manipulative abduction and of external and epistemic mediators is important not only to delineate the actual practice of abduction, but also to further enhance the development of programs computationally adequate in rediscovering, or discovering for the first time, for example, scientific hypotheses or mathematical theorems. The last part of the paper is devoted to illustrating the problem of the extra-theoretical dimension of reasoning and discovery from the perspective of some mathematical cases derived from calculus and geometry.

This volume is based on the papers presented at the international conference Model-Based Reasoning in Science and Technology (MBR09_BRAZIL), held at the University of Campinas (UNICAMP), Campinas, Brazil, December 2009. The presentations given at the conference explored how scientific cognition, but several other kinds as well, use models, abduction, and explanatory reasoning to produce important or creative changes in theories and concepts. Some speakers addressed the problem of model-based reasoning in technology, and stressed the issue of science and technological innovation. (...) The various contributions of the book are written by interdisciplinary researchers who are active in the area of creative reasoning in logic, science, and technology: the most recent results and achievements about the topics above are illustrated in detail in the papers. The book is divided in three parts, which cover the following main areas: part I, abduction, problem solving, and practical reasoning; part II: formal and computational aspects of model based reasoning; part III, models, mental models, representations.

Finally, some examples of computational programs that simulate geometrical reasoning are illustrated. The computational embodiment generates a kind of squared epistemic mediator: geometrical construction, as an example of epistemic mediator, is further mediated. (shrink)

This paper deals with the modal logics associated with (possibly nonstandard) provability predicates of Peano Arithmetic. One of our goals is to present some modal systems having the fixed point property and not extending the Gödel-Löb system GL. We prove that, for every has the explicit fixed point property. Our main result states that every complete modal logic L having the Craig's interpolation property and such that , where and are suitable modal formulas, has the explicit fixed point property.

In her book Abductive Reasoning Atocha Aliseda (2006) stresses the attention to the logical models of abduction, centering on the semantic tableaux as a method for extending and improving both the whole cognitive/philosophical view on it and on other more restricted logical approaches. I will provide further insight on two aspects. The first is re-lated to the importance of increasing logical knowledge on abduction: Aliseda clearly shows how the logical study on abduction in turn helps us to extend and modernize (...) the classical and received idea of logic. The second refers to some ideas coming from the so-called distributed cognition and concerns the role of logical models as forms of cognitive exter-nalizations of preexistent in-formal human reasoning performances. The logical externalization in objective systems, communicable and sharable, is able to grant stable perspectives endowed with symbolic, abstract, and rigorous cogni-tive features. I will also emphasize that Aliseda especially stresses that this character of stability and objectivity of logical achievements are not usually present in models of abduction that are merely cognitive and epistemological, and of ex-treme importance from the computational point of view.

This paper examines the email discursive practices of particular speakers of two different languages, namely Peninsular Spanish and British English. More specifically, our study focuses on (in)formality and (in)directness therein, for these lie at the heart of considerable scholarly debate regarding, respectively (i) the general stylistic drift towards orality and informality in technology-mediated communication, and (ii) the degree of communicative (in)directness - within broader politeness orientations - of speakers of different languages, specifically an orientation towards directness in Peninsular Spanish vis-à-vis (...) indirectness in British English. The aim of this paper is thus to investigate the role of (in)formality and (in)directness in email messages sent by members of two groups of undergraduate students to their university lecturers. To this end, a corpus of 100 impromptu emails was compiled and analysed. Results revealed complex, fluctuating patterns regarding levels of (in)formality and (in)directness that underlined cross-cultural variation in the way that different sociopragmatic principles found expression in a specific computer-mediated communicative situation.

El cine se ha descubierto como una herramienta efectiva y útil para el estudio de la Historia y la Sociología. Esa es la intención del análisis de dos películas clásicas del cine español como son ‘Historias de la Radio’ e ‘Historias de la Tele’, ambas dirigidas por el polémico José Luis Sáenz de Heredia, conocido por sus lazos familiares con el creador de Falange Española y su relación con el General Franco. Lejos de polémicas controversias y lecturas políticas, este artículo (...) intenta describir las diferencias entre la sociedad española de los años 50 y 60 usando el cine como base para el análisis.

The main goal of this work is to place the Regional History of Education into the broader context of general history and to create a theoretical structure that includes its main approaches and characteristics while avoiding the frequent confusions and oversights with which it is often associated. Our outline of regional history alludes to its conceptual foundations, defines the object of its analysis and also identifies the convergence of factors that shape this area of study, such as genealogy, multicentrism, comparison (...) and social synthesis. Once these different aspects have been described it will be easier to understand that the past is not only a dependent variable of time but also, to a great degree, of space. (shrink)
