Le réalisme métaéthique face à la science : un rapport conflictuel

Cet article traite d'un problème de métaéthique : la question de la possibilité du réalisme moral. Nous aborderons cette question à partir de ce que nous appellerons le point de vue du philosophe scientifique. L'objectif est de montrer l'incompatibilité de ce point de vue avec une position réaliste. La structure de l'article est la suivante. Nous commencerons par quelques éclaircissements terminologiques afin que le lecteur puisse se faire une idée précise de ce que nous entendons par réalisme moral (nous déclinerons notamment les différentes variantes possibles du réalisme au moyen d'un tableau) et point de vue scientifique sur la morale. Notre travail consistera ensuite à montrer de manière systématique qu'aucune des variantes du réalisme moral n'est acceptable pour un philosophe scientifique.

The subjectivist interpretation of probability and the problem of individualisation in forensic science

This paper presents and discusses further aspects of the subjectivist interpretation of probability (also known as the 'personalist' view of probabilities) as initiated in earlier forensic and legal literature. It shows that operational devices to elicit subjective probabilities - in particular the so-called scoring rules - provide additional arguments in support of the standpoint according to which categorical claims of forensic individualisation do not follow from a formal analysis under that view of probability theory.

New perspectives in the use of ink evidence in forensic science: Part II. Development and testing of mathematical algorithms for the automatic comparison of ink samples analysed by HPTLC

In the first part of this research, three stages were stated for a program to increase the information extracted from ink evidence and maximise its usefulness to the criminal and civil justice system. These stages are (a) develop a standard methodology for analysing ink samples by high-performance thin layer chromatography (HPTLC) in reproducible way, when ink samples are analysed at different time, locations and by different examiners; (b) compare automatically and objectively ink samples; and (c) define and evaluate theoretical framework for the use of ink evidence in forensic context. This report focuses on the second of the three stages. Using the calibration and acquisition process described in the previous report, mathematical algorithms are proposed to automatically and objectively compare ink samples. The performances of these algorithms are systematically studied for various chemical and forensic conditions using standard performance tests commonly used in biometrics studies. The results show that different algorithms are best suited for different tasks. Finally, this report demonstrates how modern analytical and computer technology can be used in the field of ink examination and how tools developed and successfully applied in other fields of forensic science can help maximising its impact within the field of questioned documents.

Fructose toxicity: is the science ready for public health actions?

PURPOSE OF REVIEW: The assumption that fructose may be toxic and involved in the pathogenesis of noncommunicable diseases such as obesity, diabetes mellitus, dyslipidemia, and even cancer has resulted in the call for public health action, such as introducing taxes on sweetened beverages. This review evaluates the scientific basis for such action. RECENT FINDINGS: Although some studies hint towards some potential adverse effects of excessive fructose consumption especially when combined with excess energy intake, the results from clinical trials do not support a significant detrimental effect of fructose on metabolic health when consumed as part of a weight-maintaining diet in amounts consistent with the average-estimated fructose consumption in Western countries. However, definitive studies are missing. SUMMARY: Public health policies to eliminate or limit fructose in the diet should be considered premature. Instead, efforts should be made to promote a healthy lifestyle that includes physical activity and nutritious foods while avoiding intake of excess calories until solid evidence to support action against fructose is available. Public health is almost certainly to benefit more from policies that are aimed at promoting what is known to be good than from policies that are prohibiting what is not (yet) known to be bad.

Les arènes de la normalisation internationale à l'épreuve de la participation : le projet INTERNORM

Our paper presents a pilot project (INTERNORM) funded by the University of Lausanne to support the involvement of not-for-profit organisations in international standard setting bodies such as the ISO. It analyses preliminary results on how a distinct participatory mechanism can influence the institutional environment of technical diplomacy in which ISO standards are developed. It reflects on the contribution of innovative deliberative mechanisms to democratise the field of international standardisation, largely dominated by expert knowledge and market players. It draws upon international relations literature on new institutional forms in global governance and social studies of science on participatory issues in science-society relations. The paper argues that there are significant limitations to the rise of civil society participation in such global governance mechanisms and examines several types of barriers to the involvement of not-for-profit organisations in ISO standard-setting processes. Notre communication porte sur un projet pilote (INTERNORM) financé par l'Université de Lausanne pour favoriser l'implication des acteurs associatifs dans l'élaboration des normes internationales de type ISO. Elle analyse les effets d'un dispositif participatif sur l'environnement institutionnel très particulier de la diplomatie technique ayant cours à l'ISO. Elle présente les résultats intermédiaires d'une réflexion sur l'apport de dispositifs délibératifs pour démocratiser le champ de la normalisation internationale, largement dominé par le savoir expert et les acteurs économiques. Elle situe cette réflexion au croisement des travaux de relations internationales sur les nouvelles formes institutionnelles de la gouvernance de la mondialisation et des études sociales des sciences et des techniques sur la participation dans les rapports science - société. En identifiant plusieurs registres dans lesquels situer les difficultés d'une plus grande implication des acteurs associatifs dans les procédures d'élaboration de spécifications techniques de type ISO, nous posons l'hypothèse qu'il existe d'importantes limites à l'accroissement de la dimension participative de la gouvernance globale.
