The ecology of fear has become a common rhetoric in efforts to support climate mitigation. The thesis of the collapse is an extreme version, asserting the inevitable collapse of the world. Fear, then, becomes the ultimate emotion for spurring action. In this article, drawing on the work of the pragmatist John Dewey, we show that fear is an ambiguous emotion. Dewey stressed the quality of an emotion. Following his reasoning, this article draws a distinction between intense and moderate fear. Intense (...) fear annihilates action, while moderate fear fulfils the conditions for an emotion of quality (in the Deweyan sense), which enables action. For this reason, the thesis of the collapse must be rejected, while an ecology of fear, drawing on moderate fear, may be maintained. (shrink)

Fair Trade has changed considerably since its early days. In this article, we argue that these changes have led to a depersonalization of ethics, thus raising serious questions about the future of Fair Trade. In particular, the depersonalization of ethics which is seen to accompany the current changes has led to greater variety in the interpretations of Fair Trade. Hiding these divergences behind the labels is increasing the risk that the movement will lose its credibility.

Fair trade is a new form of commercial partnership whereby actors in the North engage with actors in the South on a number of conditions, including setting a minimum price, a development bonus, and so on. But above all, fair trade organizations in the South are implementing mechanisms that more or less facilitate the empowerment of their members. This article analyzes the empowerment effects of two fair trade organizations in South India. It shows that while positive effects can be seen, (...) the prevailing social norms in India are extremely influential for women at the moment, so that women are putting all their hopes on their daughters through their education.

Environmental ethics and environmental justice have followed widely disparate paths, and this disassociation has resulted in an analytical schism. On the one side, environmental ethics embraces humankind’s relations with nature; on the opposite side, environmental justice embraces human-to-human relations via the medium of nature. Hans Jonas’ work is a bridge that crosses this conceptual divide: he spotlights the narrow correlation between human identity and responsibility, and insists on their inextricable bond with nature. However, this bond is a de facto bond (...) that all human beings have with each other. (shrink)

This case study introduces the QIT Madagascar Minerals (QMM) SA mining project at Fort-Dauphin, Madagascar, as a development project that has produced issues concerning justice. Although QMM appears to be a model company with a project that is seen as a success story, its consequent displacement of populations has been problematic in many respects, as have been the social effects that arise due to migration to the area by others who are attracted by the project. We suggest that the root (...) of many of these problems is that the people to be displaced have played an insignificant role in forming the project itself: consultation has instead been centred on corporate, government and environmental NGO concerns and interests. Compensation for losses has been inadequate. As non-mining land has been set aside as an offset for the purpose of conservation, traditional livelihoods have been curtailed. A narrow and Western conception of natural conservation that forbids access by the people has ensued for lands that hav.. (shrink)

The first aim of simulation in virtual environment is to help biologists to have a better understanding of the simulated system. The cost of such simulation is significantly reduced compared to that of in vivo simulation. However, the inherent complexity of biological system makes it hard to simulate these systems on non-parallel architectures: models might be made of sub-models and take several scales into account; the number of simulated entities may be quite large. Today, graphics cards are used for general (...) purpose computing which has been made easier thanks to frameworks like CUDA or OpenCL. Parallelization of models may however not be easy: parallel computer programing skills are often required; several hardware architectures may be used to execute models. In this paper, we present the software architecture we built in order to implement various models able to simulate multi-cellular system. This architecture is modular and it implements data structures adapted for graphics processing units architectures. It allows efficient simulation of biological mechanisms. (shrink)

New concepts may prove necessary to profit from the avalanche of sequence data on the genome, transcriptome, proteome and interactome and to relate this information to cell physiology. Here, we focus on the concept of large activity-based structures, or hyperstructures, in which a variety of types of molecules are brought together to perform a function. We review the evidence for the existence of hyperstructures responsible for the initiation of DNA replication, the sequestration of newly replicated origins of replication, cell division (...) and for metabolism. The processes responsible for hyperstructure formation include changes in enzyme affinities due to metabolite-induction, lipid-protein affinities, elevated local concentrations of proteins and their binding sites on DNA and RNA, and transertion. Experimental techniques exist that can be used to study hyperstructures and we review some of the ones less familiar to biologists. Finally, we speculate on how a variety of in silico approaches involving cellular automata and multi-agent systems could be combined to develop new concepts in the form of an Integrated cell (I-cell) which would undergo selection for growth and survival in a world of artificial microbiology.

La littérature économique s’intéresse aux enjeux du développement soutenable, mais elle aborde rarement le pilier social, car elle se concentre sur l’imbrication entre les piliers économique et environnemental. Quand il est pris en compte, le pilier social l’est comme interface qui facilite la jointure entre les deux autres. Les analyses économiques soulignent unanimement l’importance d’effectuer cette jonction, qu’il s’agisse d’évoquer les conditions de vie des populations ou l’acceptation sociale des transformations vers une transition écologique. Pourtant, les études consacrées au développement (...) soutenable ne considèrent guère le social autrement que comme une simple interface. Le social doit trouver sa juste place dans les politiques économiques de développement soutenable. Pour cela, il importe de reconceptualiser ce pilier en le faisant entrer en résonance avec les thèmes à l’origine du développement soutenable. De nouvelles justifications se présentent alors pour des politiques publiques pensées jusque là en dehors du développement soutenable. Classification JEL : Q01, Q56, Z13. (shrink)

Le commerce équitable nous invite à un réexamen des relations entre care et théories de la justice. Le commerce équitable se présente comme inscrit dans le care. Parallèlement, il réhabilite une justice aristotélicienne dite particulière. Ce faisant, il montre que éthique du care et théorie de la justice convergent, à condition que la justice ne se résume pas – comme trop souvent – à une justice dite générale. La justice particulière permet donc d’envisager autrement et de façon plus pertinente l’articulation (...) entre justice et care. Classification JEL : B11, B40, D63. (shrink)

Simulation of complex biological systems with agent-based models is becoming more relevant with the increase in Graphics Processing Unit power. In those simulations, up to millions of virtual cells are individually computed, involving daunting processing times. An important part of computational models is the algorithm that manages how agents perceive their surroundings. This can be particularly problematic in three-dimensional environments where agents have deformable virtual membranes. This article presents a GPU algorithm that gives the possibility for agents to integrate the (...) signals scattered on their virtual membrane. It is detailed to be coded in languages like OpenCL or Cuda. Its performances are tested to show its speed with current GPU devices. Finally, it was implemented inside an existing software to test and illustrate the possibilities it offers. (shrink)

L’influence du pragmatisme sur l’institutionnalisme, et notamment sur celui de John Commons, est désormais largement reconnue. En particulier, l’importance des règles et des habitudes dans les comportements a été bien mis en évidence dans le pragmatisme. Néanmoins, l’importance, dans ce courant de pensée, de la réflexion sur la bifurcation ou la rupture par rapport aux règles et aux habitudes a été minorée. Cet article souligne que John Dewey, un des pragmatistes les plus influents, a pensé ces transformations. Celles-ci sont analysées (...) chez lui à partir de trois concepts clés : l’expérience, la transaction et l’émotion. Il en découle une nouvelle piste de réflexion pour l’analyse économique, en particulier dans le rôle que les émotions peuvent jouer dans les changements par rapport aux règles et aux habitudes de comportement. Dewey nous invite ainsi à une économie de l’émotion plus riche que ce que l’analyse économique n’a produit pour l’instant. Classification JEL : B25, B40. (shrink)

While the control of cell migration by biochemical and biophysical factors is largely documented, a precise quantification of cell migration parameters in different experimental contexts is still questionable. Indeed, these phenomenological parameters can be evaluated from data obtained either at the cell population level or at the individual cell level. However, the range within which both characterizations of cell migration are equivalent remains unclear. We analyse here to which extent both sources of data could be integrated within a unified description (...) of cell migration by considering the motility of the endothelial cell line EAhy926. Using time-lapse video-microscopy and associated analysis of digital image time series, we quantified EAhy926 random motility coefficient, migration speed and trajectory persistence time in two different migration assays: the in vitro wound healing assay, and the cell-populated agarose drop assay. In order to analyse the agreement between independent quantifications of cell motility based either on individual cell analysis or cell population dynamic analysis, a theoretical multi-agents cellular model was developed and discussed as a possible theoretical framework able to unify these multi-scale data. Model simulations especially reveal the potential bias induced by cell proliferation and cell-cell adhesion when cell migration parameters are estimated from the extensively used in vitro wound healing assay.

Directive 95/46/EC and implementing legislation define the respective obligations and liabilities of the different actors that may be involved in a personal data processing operation. There are certain exceptions to the scope of these regulations, among which processing which is carried out by natural persons in the course of activities that may be considered ‘purely personal’. The purpose of this article is to investigate the liability of users of social network sites under data protection and to assess the extent to (...) which the current data protection framework can sufficiently accommodate the new realities of web 2.0 and social networking applications.
