Ce texte entend réévaluer l'idée de "pure synthèse intellectuelle" que l'on trouve chez Kant. Celle-ci cadre avec la pratique mathématique et métamathématique postérieure à Kant. Elle permet de dépasser l'alternative entre l'intuitionnisme développé dans la Critique de la raison pure et la fondation de la mathématique sur une logique formelle analytique. Je montre que cette idée convient à Bolzano et à Dedekind, dont je soutiens que les projets sont irréductibles à du logicisme et qui sont dès lors bien plus "kantiens" qu'il n'y paraît. [less ▲]

Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother–child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20–0.71 and 0.80–1.63) per exercise. The results revealed relative standard deviations of 7.87–13.55% and 4.04–11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury. [less ▲]

In this paper, the overvoltage problems that might arise from the integration of photovoltaic panels into low-voltage distribution networks is addressed. A distributed scheme is proposed that adjusts the reactive and active power output of inverters to prevent or alleviate such problems. The proposed scheme is model-free and makes use of limited communication between the controllers, in the form of a distress signal, only during emergency conditions. It prioritizes the use of reactive power, while active power curtailment is performed only as a last resort. The behavior of the scheme is studied using dynamic simulations on a single low-voltage feeder and on a larger network composed of 14 low-voltage feeders. Its performance is compared to a centralized scheme based on the solution of an Optimal Power Flow problem, whose objective function is to minimize the active power curtailment. The proposed scheme successfully mitigates overvoltage situations due to high photovoltaic penetration and performs almost as well as the Optimal Power Flow based solution with significantly less information and communication requirements.

Objective: Based on the case study of Jeanne, the objective of this article is to study patterns of anorexic people’s specific being-in-the-world. We seek to identify the core vulnerability features of anorexic existence, beyond the dimension of feeding alone. The identification of a psychopathological structure will result in a better understanding of Jeanne’s clinical situation and will help to formulate psychotherapeutic and prophylactic recommendations. Method: A phenomenological and ethological approach allows us to see past the strictly medical symptoms (eating disorder). The evolutionary perspective highlights the adaptive dimension of this disorder (e.g., in extreme situations such as famine). Specifically, Demaret’s ethological hypothesis identifies altruism (feeding altruism and generalized altruism) as the core feature of anorexic conduct. Phenomenological reflection (phenomenological psychopathology and phenomenological philosophy) appears to complement the ethological approach. Phenomenology distinguishes two kinds of bodies: the Leib (emotional, subjective and experienced in the first person) and the Körper (devitalized, objective and experienced in the second person). Merleau-Ponty’s works highlight the difference between the touching body and the touched body. These proposals show the problematic of the other in body configuration. It is in precisely this connection that anorexic existence is specific. Sartre’s phenomenology and the lived-body-for-others is the final step of our reasoning to arrive at a configuration of intersubjectivity. Results: The analysis of Jeanne’s case, combined with ethological and phenomenological perspectives, demonstrates that the real psychopathological structure of anorexic subjectivity rests on specific interaction modes. The notions of altruism, lived-body-for-others, and intersubjectivity highlight an emotional existence including shame in the eyes of others, and especially an imbalance between self-preservation and care for others. Conclusions: All our thinking suggests that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism of anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial constitutes a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Although farm tourism is an appealing idea combining agriculture and tourism, the chance to succeed in both activities is low. The Farm tourism experiments are supplied, imagined and experimented in different ways. Consequently definitions, practices and perceptions of agritourism or farm tourism differ as well. Using Gunn’s image typology the paper analyses induced, organic and modified by experience images of argitourism. The study combines data issued from a survey amongst tourists (n = 230), 26 tourism farm holders’ life stories and 31 interviews with experts conducted both in Wallonia and Grand Duchy of Luxembourg. It scrutinizes the promotional discourses, the life experience and the strategy of farm tourism holders, the expectations of tourists who have experimented farm tourism or not, who claim living in the countryside or not. The level of expectations regarding reception, authenticity, convenience, and active participation in farm works differ noticeably and are now and then inconsistent with the supply and the farm activity.

The video industry in Nigeria has developed within a widely informal economic environment in which the illicit reproduction and circulation of goods were the rule rather than the exception. The informality of circulation has played a particularly influential role in both the history of the video industry and the genesis of the present crisis. While, on the one hand, it has made videos available all over the African continent and within the diaspora, creating the basis for Nollywood’s international success, it has, on the other hand, weakened the industry’s economy, exposing it to consecutive cycles of saturation and collapse. For this reason, the production crisis that emerged over the past few years has catalyzed numerous controversies concerning the structure of the video economy and the rules that regulate it. The informality on which the video economy has been based since its inception is today often considered a threat to the survival of the industry itself. While the industry has achieved global recognition, the economic fragility of its success has provoked growing anxiety. This anxiety has been progressively concentrated, by both media and video entrepreneurs, on issues of piracy and copyright protection. The aim of this chapter is to investigate the causes of this anxiety and the role that piracy and transformations in copyright legislation have had in catalysing it, while shaping the economy of the industry. Throughout this chapter I will argue that when the uncontrolled circulation of goods begins to undermine the economic basis of the industry that produces them, the rhetoric of piracy is mobilized to ensure the accessibility to the economy of both the production and the distribution of the goods themselves. This allows some of the entrepreneurs involved in the production process to gain exclusive control over it and the capital it generates. Within the Nigerian context, the rhetorical construction of piracy and the legal and economic consequences of this construction are the result of specific conflicts among different segments of the Nigerian video industry and, more precisely, different models of economic entrepreneurship. As the history of the Nigerian video phenomenon shows, a loose copyright regime seems to have positive consequences for the emergence and early development of a creative industry, although, once the industry seeks to attain higher levels of profitability, it tends to become problematic, and the rhetoric of piracy can become a tool to orient processes of restructuration of the cultural industry’s economy. In relation to this dynamic, I analyse the way in which the normative orders that regulate the reproduction and circulation of images and contents developed within the Nigerian context, and I discuss how their introduction and implementation progressively shaped people’s perception of legal and illegal practices in the field of local cultural production.

INTRODUCTION: Antifungal resistance is an emerging problem that increases morbidity and mortality in immunosuppressed pediatric patients, who suffer from invasive fungal diseases. Optimal pharmacological management is critical for the successful treatment of invasive fungal infections by resistant strains. AREAS COVERED: This paper reviews the mechanisms of resistance of different classes of antifungal agents and the current understanding of pediatric antifungal pharmacology for overcoming antifungal resistance in children based on laboratory and clinical studies in the English literature. The therapeutic choices against fungal pathogens with intrinsic or acquired resistance are further reviewed. EXPERT OPINION: There is a paucity of data in the pediatric population regarding the epidemiology of the resistant organisms to different antifungal agents. It is also unknown if there are more prevalent molecular mechanisms that promote antifungal resistance. Selection and dosages of the most effective antifungal agent for overcoming the antifungal resistance is crucial. However, there are limited studies guiding the optimal dosage and duration of treatment for management of emergent antifungal resistance. Further studies are warranted to elucidate the optimal pharmacology of the current antifungal agents against resistant organisms and to advance the development of new antifungal agents. [less ▲]

The paper first distinguishes ritual action for sovereigns, which integrates the honoured rulers at a practical level within the religious life of a community, from other, more discrete configurations of the relation between royal and divine power. Among these trends, focus is on the rhetorical and spectacular dimension of wonder. The strategies of wonder-making are first studied in theory through paradoxography, then the categories of grandeur, exoticism and technical excellence are identified in action in Alexandrian religious life and festivals. Master of an empire with universal claims and collector of everything that is beautiful, rare and precious in the world, the king distances himself from his subjects in order to make his superior status explicit. Distance is, however, only the premise for the king to manifest himself to the great public through epiphanies that can be compared with those of divine power. The paper also discusses the way the conformism of court elites not only satisfied their own need to claim for distinguished social status, but also helped royal message spread and caused loyalty to it.

WVO Quine questions the « myth » of an ideal realm of shared meanings which every national language would express in its own way. Against the hope of transparent translations, he insists on the necessity for building equivalences from one language to another through a strategy of reducing the differences in rationality among nations as much as possible. According to Quine, otherness is not insuperable impediment to meeting/encounter and mutual understanding ; by throwing our conceptual schemes on the other communities’ uses/practices – which of course involves some symbolic violence – gaps can always been narrowed. Similarly E. Laclau questions the traditional conception of political representation, which is seen as the transparent process of transmitting someone’s will or interests on another level. For this ideal conception of representation, Laclau substitutes a pragmatic conception which takes in account the irreducible gap between the actors as well as the constitutive opacity of the process of representation : the subject’s will is constituted within the process of representation and through the representative’s productive role. In order to be transposed at the decision-making level, the subject’s interests must be translated by the representative as well as be negotiated with the other represented interests. This implies that the initial will undergoes some identity transformations. [less ▲]

This paper focuses on the computation of asymptotic standard errors (ASE) of ability estimators with dichotomous item response models. A general framework is considered and ability estimators are defined from a very restricted set of assumptions and formulas. This approach encompasses most standard methods such as maximum likelihood, weighted likelihood, maximum a posteriori and robust estimators. A general formula for the ASE is derived from the theory of M-estimation. Well-known results are found back as particular cases for the maximum and robust estimators, while new ASE proposals for the weighted likelihood and maximum a posteriori estimators are presented. These new formulas are compared to traditional ones by means of a simulation study under Rasch modeling. [less ▲]

Disulfide bonds are post-translational modifications (PTMs) often found in peptides and proteins. They increase their stability towards enzymatic degradations, and provide the structure and (consequently) the activity of such folded proteins. The characterization of disulfide patterns, i.e the cysteine connectivity, is crucial to achieve a global picture of the active conformation of the protein of interest. Electron Transfer Dissociation (ETD) constitutes a valuable tool to cleave the disulfide bonds in the gas phase, avoiding chemical reduction/alkylation in solution. To characterize the cysteine pairing, the present work proposes (i) to reduce by ETD one of the two disulfide bridges of model peptides , resulting in the opening of the cyclic structures, (ii) to separate the generated species by ion-mobility and, (iii) to characterize the species using CID. Results of this strategy applied to several peptides show different behaviors depending on the connectivity. The loss of SH• radical species, observed for all the peptides, confirms the cleavage of the disulfides during the ETD process. [less ▲]
