Methods dealing with how to contact other planets that are supposed to be inhabited by intelligent civilizations have begun more than one century and a half ago. The historical question has been already treated in several studies and the aim of this paper is not to provide details on that aspect. On the other hand, it could be interesting to make a comparison between the different approaches to contact planets, formulated at different epochs (even if obviously techniques were not in the same state of advancement). The most important characteristics of the earliest messages, remained only on a theoretical form, will be presented. The main features of modern messages, which have been concretely realized, will also be emphasized. Drawing a parallel between these two series of projects could demonstrate what has been considered as unavoidable by both pioneer and modern messages creators, while it has not been proved that the first ones have had any influence on the second ones. The common points emerging from this comparison could then (perhaps) help to select adequate models for an intelligible message intended to ETs, particularly concerning the language forms. Besides this, the differences could illustrate the human cultural advances in the field of METI and underline the tendencies that have been chosen in that field since the last decades. © 2011 Elsevier Ltd.

An overview of the scientific literature shows that the concept of function is central in physiology. However, the concept itself is not defined by physiologists. On the other hand, the teleological, namely, the 'goal-directed' dimension of function, and its subsequent explanatory relevance, is a philosophical problem. Intuitively, the function of a trait in a system explains why this trait is present, but, in the early 1960s, Ernest Nagel and Carl Hempel have shown that this inference cannot be logically founded. However, they showed that self-regulated systems are teleological. According to the selectionist theories, the function of an item is its effect that has been selected by natural selection, a process that explains its presence. As they restrict the functional attribution of a trait to its past selective value and not its current properties, these theories are inconsistent with the concept of function in physiology. A more adequate one is the causal role theory, for which a function of a trait in a system is its causal contribution to the functional capacity of the system. However, this leaves unsolved the question of the 'surplus meaning' of the teleological dimension of function. The significance of considering organisms as 'purpose-like' (teleological) systems may reside not in its explanatory power but in its methodological fruitfulness in physiology. In this view, the teleological dimension of physiological functions is convergent to but not imported from, the teleological dimension of evolutionary biology. © 2014 The Physiological Society.

Charles Kingsley's Alton Locke (1850), written a decade before the publication of Charles Darwin's theory of natural selection, emphasizes newly-emerging definitions of nature and modern perceptions of the interrelations between the human social system and the ecosystem. In so doing, the modern conceptions of the natural environment which the novel highlights, shape a utopian model for a more democratic society. As this paper points out, by using environmental metaphors, Kingsley questions human nature and the potential of the environment to change it. As a result, his depiction of natural ecosystems, though charged with ideology and the weight of conservative discourse, is progressive, inviting humans to change society-and themselves in the process. © 2013 by Koninklijke Brill NV, Leiden, The Netherlands.

Biodiversity offsetting is now a widespread tool in industrialised states, especially in North America and the European Union where it forms a regulatory requirement. In principle, environmental assessment and the implementation of offsets mainly require ecological knowledge. However, in practice, by relying upon the equity and exchangeability of the habitats concerned, biodiversity offsetting creates some difficulties and contradictions that planners have to overcome. I make the assumption that, because of its exchangeability principle, this process also requires accounting and, more specifically, market exchange accounting. By analysing a French biodiversity offset management plan (BOMP), together with guidelines and regulations, I show that the assessment - reducing habitats to what they have in common - and equity - reducing habitats to an exchange value - proceed from market accounting and ontologically transform habitats into commodities. This viewpoint suggests that biodiversity offsetting should be endorsed very cautiously by conservation biology as it produces strong normative outlines compatible with a commodification process. © 2015 Elsevier B.V.

By focusing on funding methods, this paper considers the way in which medical research eventually led to the science-based medicine that is prevalent in France today. This process seems to have taken place in three stages during the second half of the twentieth century. In the 1940s and 1950s, two major events occurred. The first was the creation of a national health insurance fund in France, which opened up new reasons for, and ways of, funding medical research. The second was the development of antibiotics, which triggered a revival of clinical medicine. In the 1960s and 1970s, a proactive government science policy allowed the life sciences and medical research to come together in the wake of a burgeoning new science: molecular biology. Thus, in 1964, the creation of the National Health and Medical Research Institute (Institut national de la santé et de la recherche médicale or INSERM), destined to "molecularize" medical research, was seen as the fulfillment of the government's ambitious research policy. Today, with medicine irreversibly embedded in scientific and technical rationality, health has become a major issue in modern societies. This paper therefore touches on some of the key features of biomedical research, including the revival of funding systems for clinical research and the development of a system of research grants that was made possible by patient organizations and the creation of new funding agencies.
