This paper presents findings from a linguistic and psychosocial analysis of nine design dialogues that sets out to investigate the interweaving of transactional and interpersonal threads in collaborative work. We sketch a model of the participants' positioning towards their own or their partner's design proposals, together with the conversational cues which indicate this positioning. Our aim is to integrate the role of interpersonal relationships into the study of cooperation, to stress the importance of this dimension for the quality of collective (...) work and to reflect on its potential for integration into the design of dialogue systems.

This paper seeks to reinterpret the life and work of J. B. S. Haldane by focusing on an illuminating but largely ignored essay he published in 1927, "The Last Judgment" -- the sequel to his better known work, "Daedalus" (1924). This astonishing essay expresses a vision of the human future over the next 40,000,000 years, one that revises and updates Wellsian futurism with the long range implications of the "new biology" for human destiny. That vision served as a kind of (...) lifelong credo, one that infused and informed his diverse scientific work, political activities, and popular writing, and that gave unity and coherence to his remarkable career.

A major distinction in the social organization of ant societies is the number of reproductive queens that reside in a single colony. The fire ant Solenopsis invicta exists in two distinct social forms, one with colonies headed by a single reproductive queen and the other containing several to hundreds of egg‐laying queens. This variation in social organization has been shown to be associated with genotypes at the gene Gp‐9. Specifically, single‐queen colonies have only the B allelic variant of this gene, (...) whereas multiple‐queen colonies always have the b variant as well. Subsequent studies revealed that Gp‐9 shares the highest sequence similarity with genes encoding pheromone‐binding proteins (PBPs). In other insects, PBPs serve as central molecular components in the process of chemical recognition of conspecifics. Fire ant workers regulate the number of egg‐laying queens in a colony by accepting queens that produce appropriate chemical signals and destroying those that do not. The likely role of GP‐9 in chemoreception suggests that the essential distinction in colony queen number between the single and multiple‐queen form originates from differences in workers' abilities to recognize queens. Other, closely related fire ant species seem to regulate colony social organization in a similar fashion. BioEssays 27:91–99, 2005. © 2004 Wiley Periodicals, Inc. (shrink)

H. B. D. Kettlewell's field experiments on industrial melanism in the peppered moth, Biston betularia, have become the best known demonstration of natural selection in action. I argue that textbook accounts routinely portray this research as an example of controlled experimentation, even though this is historically misleading. I examine how idealized accounts of Kettlewell's research have been used by professional biologists and biology teachers. I also respond to some criticisms of David Rudge to my earlier discussions of this case study, (...) and I question Rudge's claims about the importance of purely observational studies for the eventual acceptance and popularization of Kettlewell's explanation for the evolution of industrial melanism.

This article is an edited transcript of the roundtable entitled “What is Philo-Performance?” that took place in Paris on 28 June 2014, within the framework of the “Theatre, Performance, Philosophy International Conference: Crossings and Transfers in Anglo-American Thought”. The conference was organized by Julien Alliot, Flore Garcin-Marrou, Liza Kharoubi and Anna Street from the LAPS, a French research group on performance philosophy.

The paper illustrates how organic chemists dramatically altered their practices in the middle part of the twentieth century through the adoption of analytical instrumentation - such as ultraviolet and infrared absorption spectroscopy and nuclear magnetic resonance spectroscopy - through which the difficult process of structure determination for small molecules became routine. Changes in practice were manifested in two ways: in the use of these instruments in the development of 'rule-based' theories; and in an increased focus on synthesis, at the expense (...) of chemical analysis. These rule-based theories took the form of generalizations relating structure to chemical and physical properties, as measured by instrumentation. This 'Instrumental Revolution' in organic chemistry was two-fold: encompassing an embrace of new tools that provided unprecedented access to structures, and a new way of thinking about molecules and their reactivity in terms of shape and structure. These practices suggest the possibility of a change in the ontological status of chemical structures, brought about by the regular use of instruments. The career of Robert Burns Woodward (1917-1979) provides the central historical examples for the paper. Woodward was an organic chemist at Harvard from 1937 until the time of his death. In 1965, he won the Nobel Prize in Chemistry. (shrink)
