The so-called “disquotational theory of truth” has not previously been developed much beyond the thesis that saying, for example, that ‘Snow is white’ is true amounts only to saying that snow is white. Marian David has set out to see what further sense can be made of the disquotational theory, and to compare its merits with those of correspondence theories of truth. His prognosis is that an intelligible disquotational theory of truth can be developed but will suffer from drastic (...) shortcomings that make it all but unusable. (shrink)
O artigo procura mostrar, com base no parágrafo 17 do Tratado da Emenda do Intelecto, a centralidade do conceito de vulgo para a interpretação da obra de Espinosa. Para tanto, discute-se a relação entre imagens e conceitos na teoria do conhecimento em Espinosa, bem como a relação entre linguagem e filosofia.
This work on the theory of education was first published in 1839. The five writers had been chosen as the winners in a competition for an essay on the 'Expediency and Means of Elevating the Profession of the Educator in Society', organised by the Central Society of Education, founded in 1837 to promote state funding of education, at a time when the 'monitor' system, whereby older children taught younger ones, was seen as an effective method. The journalist John Lalor won (...) first prize with a wide-ranging consideration of all the aspects of education, comparing the status of teachers through history and across several countries, and championing their 'sacred mission'. The runners-up were the writer John A. Heraud, the Unitarian minister Edward Higginson, the lawyer and author James Simpson, and Mrs Sarah Porter, prolific writer on education and sister of the political economist David Ricardo. (shrink)
This paper presents a series of 4 single subject experiments aimed to investigate whether children with autism show more social engagement when interacting with the Nao robot, compared to a human partner in a motor imitation task. The Nao robot imitates gross arm movements of the child in real-time. Different behavioral criteria (i.e. eye gaze, gaze shifting, free initiations and prompted initiations of arm movements, and smile/laughter) were analyzed based on the video data of the interaction. The results are mixed (...) and suggest a high variability in reactions to the Nao robot. The results are as follows: For Child2 and Child3, the results indicate no effect of the Nao robot in any of the target variables. Child1 and Child4 showed more eye gaze and smile/laughter in the interaction with the Nao robot compared to the human partner and Child1 showed a higher frequency of motor initiations in the interaction with the Nao robot compared to the baselines, but not with respect to the human-interaction. The robot proved to be a better facilitator of shared attention only for Child1. Keywords: human-robot interaction; assistive robotics; autism. (shrink)
This paper aims to study the role of the social robot Probo in providing assistance to a therapist for robot assisted therapy (RAT) with autistic children. Children with autism have difficulties with social interaction and several studies indicate that they show preference toward interaction with objects, such as computers and robots, rather than with humans. In 1991, Carol Gray developed Social Stories, an intervention tool aimed to increase children's social skills. Social stories are short scenarios written or tailored for autistic (...) individuals to help them understand and behave appropriately in social situations. This study shows that, in specific situations, the social performance of autistic children improves when using the robot Probo, as a medium for social story telling, than when a human reader tells the stories. The robot tells Social Stories to teach ASD children how to react in situations like saying “hello“, saying “thank you“ and “sharing toys“. The robot has the capability of expressing emotions and attention via its facial expressions and its gaze. The paper discusses the use of Probo as an added-value therapeutic tool for social story telling and presents the first experimental results. Keywords: social robot; ASD children; social story; robot assisted therapy. (shrink)
This paper examines some economic forecasts made in late 1930 that were intended to predict economic activity in the United States in order to shed light on several methodological issues. We document that these forecasts were extremely optimistic, predicting that the recession in the US would soon end, and that 1931 would show a recovery. These forecasts displayed egregious errors, because 1931 witnessed the largest negative growth rate for the US economy in any year in the twentieth century. A specific (...) question is what led forecasters to make such serious and substantial empirical errors. A second more general issue involves the methodology of forecasting. The 1930 forecasts were sometimes based on explicit analogies with previous serious business cycles. Modern forecasting approaches are based on techniques that may not be recognized as analogies. Using the 1930 forecasts, we examine the implicit?analogy content of forecasts, and what might render such implicit analogies valid or invalid. This 1930 forecast example also resonates beyond the confines of economic methodology because forecasts about the Great Depression are of continuing interest to the profession at large, and we produce a forecast series not previously available.

Filled with insightful reflections on teaching oral history, it offers practical suggestions for educators seeking to create curricula, engage students, gather community support, and meet educational standards. By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.
It is common to regard love, friendship, and other associational ties to others as an important part of a happy or flourishing life. This would be easy enough to understand if we focused on friendships based on pleasure, or associations, such as business partnerships, predicated on mutual advantage. For then we could understand in a straightforward way how these interpersonal relationships would be valuable for someone involved in such relationships just insofar as they caused her pleasure or causally promoted her (...) own independent interests. But many who regard love, friendship, and other associational ties as an important part of a happy or flourishing life suppose that in many sorts of associations—especially intimate associations—the proper attitude among associates is concern for the other for the other's own sake, not just for the pleasure or benefits one can extract from one's associates. It is fairly clear how having friends of this sort is beneficial. What is less clear is how being a friend of this sort might contribute to one's own happiness or well-being. Even if we can explain this, it looks as if the contribution that friendship makes to one's happiness could not be the reason one has to care for friends, for that would seem to make one's concern for others instrumental, not a concern for the other for her own sake.
