Dans les heures de grandes trouvailles, une image poétique peut être le germe d'un monde, le germe d'un univers imaginé devant la rêverie d'un poète. La conscience d'émerveillement devant ce monde créé par le poète s'ouvre en toute naïveté. [...] L'exigence phénoménologique à l'égard des images poétiques est d'ailleurs simple : elle revient à mettre l'accent sur leur vertu d'origine, à saisir l'être même de leur originalité et à bénéficier ainsi de l'insigne productivité psychique qui est celle de l'imagination.

Abundant research exists on the restructuring operations of large, publicly listed firms. However, little is known about the antecedents of layoffs in small and medium-sized enterprises (SMEs). Building on the stakeholder salience theory and arguments on social proximity, this study posits that SMEs are less likely to dismiss employees than large firms. We argue that the existence of strong interpersonal ties between employees and managers makes it hard for SME owners and managers to dismiss employees. Empirically analyzing a large sample (...) of European Union firms, the results confirm that the likelihood of layoffs is lower in SMEs than in large firms, even when performance declines. (shrink)

This paper presents a computational model of the way humans inductively identify and aggregate concepts from the low-level stimuli they are exposed to. Based on the idea that humans tend to select the simplest structures, it implements a dynamic hierarchical chunking mechanism in which the decision whether to create a new chunk is based on an information-theoretic criterion, the Minimum Description Length (MDL) principle. We present theoretical justifications for this approach together with results of an experiment in which participants, exposed (...) to meaningless symbols, have been implicitly encouraged to create high-level concepts by grouping them. Results show that the designed model, called hereafter MDLChunker, makes precise quantitative predictions both on the kind of chunks created by the participants and also on the moment at which these creations occur. They suggest that the simplicity principle used to design MDLChunker is particularly efficient to model chunking mechanisms. The main interest of this model over existing ones is that it does not require any adjustable parameter. (shrink)

Psychology distinguishes between a bodily and a narrative self. Within neuroscience, models of the bodily self are based on exteroceptive sensorimotor processes or on the integration of interoceptive sensations. Recent research has revealed interactions between interoceptive and exteroceptive processing of self-related information, for example that mirror self-observation can improve interoceptive awareness. Using heartbeat perception, we measured the effect on interoceptive awareness of two experimental manipulations, designed to heighten attention to bodily and narrative aspects of the self. Participants gazed at a (...) photograph of their own face or at self-relevant words. In both experimental conditions interoceptive awareness was significantly increased, compared to baseline. Results show that attention to narrative aspects of self, previously regarded as relying on higher-order processes, has an effect similar to self-face stimuli in improving interoceptive awareness. Our findings extend the previously observed interaction between the bodily self and interoception to more abstract amodal representations of the self. (shrink)

ABSTRACTOscar Larsson’s essay condemns discursive institutionalism for the “sin” of subjectivism. In reality, however, discursive institutionalism emphasizes the intersubjective nature of ideas through its theorization of agents’ “background ideational abilities” and “foreground discursive abilities.” It also avoids relativism by means of Wittgenstein’s distinction between experiences of everyday life and pictures of the world. Contrary to Larsson, what truly separates post-structuralism from discursive institutionalism is the respective approaches’ theorization of the relationship of power to ideas, with discursive institutionalists mainly focused on (...) persuasive power through ideas, while post-structuralists focus on the structural power in ideas or on coercive power over ideas.

The authors of this essay reflect on the experience of co-teaching a course on the history of genetics and race. The collaboration has pushed them both—a historian of science and a biologist—to consider how to make space for moral and scientific judgment in a history classroom. Drawing on examples from the course, they argue that it is possible to encourage social action and thoughtful critiques of past and current science without succumbing to a whiggish narrative of progress.

This study investigates moments in which one participant in an interaction embodies that he is “doing thinking,” a display that is commonly referred to as “thinking face. ” From an interactional perspective, it is assumed that embodied displays of “doing thinking” are a recurring social practice and serve interactive functions. While previous studies have examined thinking faces primarily in word searches and storytelling, the present study focuses on argumentative activities, in which children engage in processes of joint decision-making. The paper (...) has two interrelated aims. The first aim is to describe how multiple modalities—beyond the face—are temporally coordinated to create multimodal gestalts of “doing thinking.” It is shown that thinking displays not only involve dynamic imaginative gaze but also stylized bodily postures. The second aim is to generate knowledge about the functions of thinking displays in children's argumentative activities. The analysis describes how both speakers and recipients use thinking displays in different turn positions and align them with verbal talk or silence. The data for this study comprise video recordings of decision-making processes in groups of older children. Drawing on a multimodal approach to situated interaction, it will be proposed that embodied displays of “doing thinking” provide a resource to shape participation frameworks, mark epistemic stances and create epistemic ecologies for collaborative reasoning. By investigating thinking displays in a particular conversational activity, the study sheds light on the diversity and context-sensitive functionality of thinking displays. It also contributes to recent research on children's collaborative reasoning as an embodied discursive practice. (shrink)

This paper focuses on some of the ethical issues which may arise when conducting research in the context of homelessness. These issues are considered from the viewpoints of researchers, research coordinators and interviewers, drawing from their extensive real world experience. In addition to negotiating the complex context of homelessness, community-based homelessness researchers need to address a number of ethical issues in research conception, design, implementation and dissemination. Although these issues are commonly considered in community-engaged research, research with people who are (...) homeless may raise exceptional challenges. Such challenges include determining the nature of informed consent; protecting research participants and researchers, and determining appropriate compensation for participation. Understanding the context of homelessness to conduct ethical research will require sharing information and joint decision-making, processes that must include members of communities within which the research participants live. Furthermore, researchers should be sensitive to the changing context of homelessness, and vigilant for new ethical challenges. (shrink)

Maria Rentetzi. Trafficking Materials and Gendered Research Practices: Radium Research in Early 20th Century Vienna.

Examines the changes during the twentieth century in the views of mathematics, physics, and the scientific method and discusses the role of the mind in science.

This study looks into the factors that foster the use of contingent employment in the Philippines, and its consequences. It also explores the relationship between corporate social performance and the nature of contingent employment. Results indicate an inverse relationship between levels of social performance and utilization of contingent employment. There is a direct relationship between the size and intensity of utilization of temporary employees and the combined effects of unionization and total employment size. Publicly listed companies exhibit higher utilization of (...) temporary employees. However, factors that foster the use of project employees need tobe explored further. Benefits are influenced by the intensity of utilization of contingent employees. Formalization of the use of contingent employees tends to blur the difference between casual and regular employees. The use of subcontracting positively influences the number of benefits provided and diminishes the differential benefits between regular and project employees. Unionization, however, tends to increase the differential benefits between regular employees and project employees. (shrink)

Sixieme livre de Gaston Bachelard, Les Intuitions atomistiques (1933), constituent une curiosite des son sous-titre : essai de classification. Loin de la methode habituelle des philosophes, familiers des monographies, l'auteur se livre ici a des comparaisons de doctrines. Une discontinuite revelant des symetries et des antisymetries, deux systemes de pensees, ramenes a leurs intuitions, sont parfois reductibles a une forme unique. L'auteur n'hesite donc pas a regrouper des mondes que tout separe : l'atomistique ancienne de Democrite et Lucrece, l'atomisme (...) positiviste et criticiste, l'atomisme axiomatique de la physique moderne. Bachelard n'est pas un historien. C'est un classificateur. (shrink)

Utilisant les concepts psychanalytiques, l'auteur montre comment, dans la science, le language constitue le véhicule privilégié de l'anthropomorphisme et comment les projections affectives constituent autant d'obstacles épistémiologiques à son développement.

Le philosophe analyse la symbolique de la flamme, qu'il qualifie d'un des plus grands opérateurs d'images parce qu'elle force l'homme à imaginer, sous des aspects philosophique, poétique, esthétique ou encore littéraire. Il humanise la flamme et la fait centre de toute demeure, un être familial gardien des souvenirs.

Pour Gaston Bachelard, le " non " signifie dépasser et compléter le savoir antérieur, la philosophie de la connaissance scientifique doit englober les contradictions, ce qu'il explique dans cet ouvrage sous-titré Essai d'une philosophie du nouvel esprit scientifique. Il établit le profil épistémologique de l'évolution, du réalisme naïf au surrationalisme en passant par le rationalisme classique et élargit le domaine de l'intuition à ce qu'il appelle une " intuition travaillée"s'exerçant dans un espace non analytique.

Utilisant les concepts psychanalytiques, l'auteur montre comment, dans la science, le language constitue le véhicule privilégié de l'anthropomorphisme et comment les projections affectives constituent autant d'obstacles épistémiologiques à son développement.

L’originalité de la philosophie de Bachelard tient à la place donnée, dans ses recherches, à l’imagination et à la poésie. En proposant « de considérer l’imagination comme une puissance majeure de la nature humaine », il a ainsi ouvert de nouveaux espaces de méditation et de réflexion philosophiques dont s’inspirent encore de nombreux philosophes.
