"Periodic crises": Clément Juglar between theories of crises and theories of business cycles

Business cycle theory is normally described as having evolved out of a previous tradition of writers focusing exclusively on crises. In this account, the turning point is seen as residing in Clément Juglar's contribution on commercial crises and their periodicity. It is well known that the champion of this view is Schumpeter, who propagated it on several occasions. The same author, however, pointed to a number of other writers who, before and at the same time as Juglar, stressed one or another of the aspects for which Juglar is credited primacy, including the recognition of periodicity and the identification of endogenous elements enabling the recognition of crises as a self-generating phenomenon. There is indeed a vast literature, both primary and secondary, relating to the debates on crises and fluctuations around the middle of the nineteenth century, from which it is apparent that Juglar's book Des Crises Commerciales et de leur Retour Périodique en France, en Angleterre et aux États-Unis (originally published in 1862 and very much revised and enlarged in 1889) did not come out of the blue but was one of the products of an intellectual climate inducing the thinking of crises not as unrelated events but as part of a more complex phenomenon consisting of recurring crises related to the development of the commercial world - an interpretation corroborated by the almost regular occurrence of crises at about 10-year intervals.

Origène et la tradition alexandrine vus par Photius dans sa Bibliothèque

(résumé de l'ouvrage) Studies on Origen at the beginning of the 21st century continue to dig old and new grounds of research. After the epoch-making rediscovery of the great Alexandrian doctor throughout the past century, contemporary research increasingly deals with the close context of his writings and thought: the cultural tradition of Alexandria in all its components - Hellenistic, Jewish, Egyptian, Gnostic and Christian. This topic was the theme chosen for the «Colloquium Origenianum Octavum» (Pisa, 27-31 August 2001), a major event of patristic scholarship. The proceedings now contain more than 100 papers of contributors from about 30 countries. They not only provide the best overview on a lively field of studies but also demonstrate how Origen's heritage in Christian history and theology carried with it the imprint of one of the most vital traditions of Western civilization.

Strategies for the development of tdm for targeted anticancer agents

Most of the novel targeted anticancer agents share classical characteristics that define drugs as candidates for blood concentration monitoring: long-term therapy; high interindividual but restricted intraindividual variability; significant drug-drug and drug- food interactions; correlations between concentration and efficacy/ toxicity with rather narrow therapeutic index; reversibility of effects; and absence of early markers of response. Surprisingly though, therapeutic concentration monitoring has received little attention for these drugs despite reiterated suggestions from clinical pharmacologists. Several issues explain the lack of clinical research and development in this field: global tradition of empiricism regarding treatment monitoring, lack of formal conceptual framework, ethical difficulties in the elaboration of controlled clinical trials, disregard from both drug manufacturers and public funders, limited encouragement from regulatory authorities, and practical hurdles making dosage adjustment based on concentration monitoring a difficult task for prescribers. However, new technologies are soon to help us overcome these obstacles, with the advent of miniaturized measurement devices able to quantify circulating drug concentrations at the point-of-care, to evaluate their plausibility given actual dosage and sampling time, to determine their appropriateness with reference to therapeutic targets, and to advise on suitable dosage adjustment. Such evolutions could bring conceptual changes into the clinical development of drugs such as anticancer agents, while increasing the therapeutic impact of population PK-PD studies and systematic reviews. Research efforts in that direction from the clinical pharmacology community will be essential for patients to receive the greatest benefits and the least harm from new anticancer treatments. The example of imatinib, the first commercialized tyrosine kinase inhibitor, will be outlined to illustrate a potential research agenda for the rational development of therapeutic concentration monitoring.

Risk of prostate, breast and colorectal cancer after skin cancer diagnosis.

Ultraviolet radiation is the major cause of skin cancer, but promotes vitamin D synthesis, and vitamin D has been inversely related to the risk of several common cancers including prostate, breast and colorectum. We therefore computed the incidence of prostate, breast and colorectal cancer following skin cancer using the datasets of the Swiss cancer Registries of Vaud and Neuchâtel. Between 1974 and 2005, 6,985 histologically confirmed squamous cell skin cancers, 21,046 basal cell carcinomas and 3,346 cutaneous malignant melanomas were registered, and followed up to the end of 2005 for the occurrence of second primary cancer of the prostate, breast and colorectum. Overall, 680 prostate cancers were observed versus 568.3 expected (standardized incidence ratio (SIR) = 1.20; 95% confidence interval (CI): 1.11-1.29), 440 breast cancers were observed versus 371.5 expected (SIR = 1.18; 95% CI: 1.08-1.30) and 535 colorectal cancers were observed versus 464.6 expected (SIR = 1.15; 95% CI: 1.06-1.25). When basal cell, squamous cell and skin melanoma were considered separately, all the SIRs for prostate, breast and colorectal cancers were around or slightly above unity. Likewise, the results were consistent across strata of age at skin cancer diagnosis and location (head and neck versus others), and for male and female colorectal cancers. These findings, based on a population with a long tradition of systematic histologic examination of all surgically treated skin lesions, do not support the hypothesis that prostate, breast and colorectal cancer risk is decreased following skin cancer.

Evaluation of an online, case-based interactive approach to teaching pathophysiology

Rapport de synthèse : L'article qui fait l'objet de ma thèse évalue une nouvelle approche pédagogique pour l'apprentissage de certains chapitres de physiopathologie. Le dispositif pédagogique se base sur l'alternance d'apprentissage ex-cathedra et de l'utilisation d'un site web comprenant des vignettes cliniques. Lors de la consultation de ces-dernières, l'étudiant est invité à demander des examens de laboratoire dont il pourrait justifier la pertinence selon le cas clinique étudié. La nouveauté du procédé réside dans le fait que, préalablement à son cours ex-cathedra, l'enseignant peut consulter les statistiques de demandes de laboratoire et ainsi orienter son cours selon les éléments mal compris par les étudiants. A la suite du cours ex-cathedra, les étudiants peuvent consulter sur internet la vignette clinique complète avec des explications. A l'issue de tout le cours, une évaluation auprès des étudiants a été conduite. Le procédé a été mis en place durant deux années consécutives et l'article en discute notamment les résultats. Nous avons pu conclure que cette méthode innovatrice d'enseignement amène les étudiants à mieux se préparer pour les cours ex-cathedra tout en permettant à l'enseignant d'identifier plus précisément quelles thématiques étaient difficiles pour les étudiants et donc d'ajuster au mieux son cours. Mon travail de thèse a consisté à créer ce dispositif d'apprentissage, à créer l'application web des vignettes cliniques et à l'implanter durant deux années consécutives. J'ai ensuite analysé les données des évaluations et écrit l'article que j'ai présenté à la revue 'Medical Teacher'. Après quelques corrections et précisions demandées par le comité de lecture, l'article a été accepté et publié. Ce travail a débouché sur une seconde version de l'application web qui est actuellement utilisée lors du module 3.1 de 3è année à l'Ecole de Médecine à Lausanne. Summary : Since the early days of sexual selection, our understanding of the selective forces acting on males and females during reproduction has increased remarkably. However, despite a long tradition of experimental and theoretical work in this field and relentless effort, numerous questions remain unanswered and many results are conflicting. Moreover, the interface between sexual selection and conservation biology has to date received little attention, despite existing evidence for its importance. In the present thesis, I first used an empirical approach to test various sexual selection hypotheses in a population of whitefish of central Switzerland. This precise population is characterized by a high prevalence of gonadal alterations in males. In particular, I challenged the hypothesis that whitefish males displaying peculiar gonadal features are of lower genetic quality than other seemingly normal males. Additionally, I also worked on identifying important determinant of sperm behavior. During a second theoretical part of my work, which is part of a larger project on the evolution of female mate preferences in harvested fish populations, I developed an individual-based simulation model to estimate how different mate discrimination costs affect the demographical behavior of fish populations and the evolutionary trajectories of female mate preferences. This latter work provided me with some insight on a recently published article addressing the importance of sexual selection for harvesting-induced evolution. I built upon this insight in a short perspective paper. In parallel, I let some methodological questions drive my thoughts, and wrote an essay about possible synergies between the biological, the philosophical and the statistical approach to biological questions.

Judaïsme : entre impératifs éthiques et normes religieuses.

(Résumé de l'ouvrage) Nos sociétés contemporaines, à l'heure de la mondialisation, ont-elles perdu le sens de l'hospitalité ? Qu'en est-il de ses fonctions et de ses figures à la fois morales, politiques, religieuses et imaginaires ? Lorsque Ulysse abordait un nouveau rivage, la même question revenait : Vais-je trouver des brutes, des sauvages sans justice ou des hommes hospitaliers craignant les dieux ? L'hospitalité a toujours été signe de civilisation et d'humanité, et les pérégrinations d'Ulysse ont su dresser une géographie imaginaire du monde humain, dessinant les contours et traçant les limites de la culture et de la nature. Considérant qu'il est urgent de retrouver cette mémoire hospitalière du monde humain, plus de quatre-vingt-dix auteurs du monde entier ont rassemblé leurs savoirs des us et coutumes, des lieux, des cultures, des représentations, des mythes et des oeuvres d'art qui font de l'hospitalité la plus indispensable des valeurs humaines. Philosophes, historiens, ethnologues, littéraires, linguistes... invitent le lecteur, leur hôte, à découvrir le vaste parcours ouvert des significations et des pratiques de l'accueil dans l'histoire culturelle. Have modern day societies in this era of globalization forgotten the sense of hospitality? Hospitality is a principle which used to play a major social function, with its symbolic, ethical, political and religious figures. This book is designed to preserve the memory of the tradition of hospitality. To that end 90 authors from throughout the world have collaborated to present this exhaustive encyclopedia of the places, the customs, the cultures, the myths and the artistic representations of hospitality, all of which bear witness to its importance as a human value. Philosophers, historians, ethnologists, writers, linguists welcome the reader to discover the place that hospitality has had in cultural history, in terms of both how and why it was practised. - This book offers a fivefold treatment of the perennial tradition of hospitality: - Definitions - Civilizations (throughout history and across religions and cultures) - Institutions and places of hospitality, both real and imaginary (castles, hospitals, gardens, churches, etc.) - Myths, figures and artistic representation - Philosophy, politics and society.

Hybrids and Regulation in the Global Political Economy

While regulation theory literature has made important contributions to the much-debated domain of globalisation by focusing on various aspects of post-Fordism, it has not yet fully engaged with the implications that can be drawn from critical approaches in international political economy. Recent studies have explored the transnational bases of new patterns and agents of change beyond states, firms and institutions traditionally involved in regulatory practices. Hybrid is often used as a default attribute reflecting lack of clear understanding of the breadth of this new type of influence and the opacity of the means involved. Drawing on the insights of philology and mythology, the paper argues that the notion of hybrid is relevant in elucidating the ontological ambiguity between imaginary and real aspects of globalisation. Furthermore, it specifies the categories involved in the analysis of emerging forms of hybrid regulation. Recent scholarship on globalisation tends to focus on the private-public nexus of the subjects involved in new forms of institutional arrangements and authority. Here, subjects, objects and space are analysed as joint issues. By focusing particularly on transformations affecting the role of the state, forms of competition, and their rescaling on a transnational basis, the concept of global hybrid is seen as complementary to the emancipation of regulation approaches from early emphasis on national levels of compromises.

Measuring alcohol-related consequences in school surveys: alcohol-attributable consequences or consequences with students' alcohol attribution.

In alcohol epidemiology surveys, there is a tradition of measuring alcohol-related consequences using respondents' attribution of alcohol as the cause. The authors aimed to compare the prevalence and frequency of self-attributed consequences to consequences without self-attribution using alcohol-attributable fractions (AAF). In 2007, a total of 7,174 Swiss school students aged 13-16 years reported the numbers of 6 alcohol-related adverse consequences (e.g., fights, injuries) they had incurred in the past 12 months. Consequences were measured with and without attribution of alcohol as the cause. The alcohol-use measures were frequency and volume of drinking in the past 12 months and number of risky single-occasion (> or =5 drinks) drinking episodes in the past 30 days. Attributable fractions were derived from logistic (> or =1 incident) and Poisson (number of incidents) regression analyses. Although relative risk estimates were higher when alcohol-attributed consequences were compared with nonattributed consequences, the use of AAFs resulted in more alcohol-related consequences (10,422 self-attributed consequences vs. 24,520 nonattributed consequences determined by means of AAFs). The likelihood of underreporting was higher among drinkers with intermediate frequencies than among either rare drinkers or frequent drinkers. Therefore, the extent of alcohol-related adverse consequences among adolescents may be underestimated when using self-attributed consequences, because of differential attribution processes, especially among infrequent drinkers.

Une première réflexion de Nicolas Jacquier concernant les démons : le De calcatione demonum seu malignorum spirituum (1457)

The De calcatione demonum seu malignorum spirituum was written in 1457 by Nicolas Jacquier, one year before his most famous work, the Flagellum hereticorum fascinariorum. The De calcatione offers initial reflections by the Burgundian dominican inquisitor on diabolical modes of actions directed at human beings and on the means at the disposal of priests and their faithful to control, expel, and trample (calcare) them. This relatively unknown text is produced at a time when purely demonological issues are linked to those on diabolical witchcraft and the sabbath. The author tries in particular to promote the idea of trampling demons, which is understood as their punishment. Now vanquished, demons are compelled to serve divine truth. In a climate of skepticism about the need to fight withcraft, the De calcatione offers an interesting reflexion about the truth status of diabolical and heretical discourses when submitted to divine power. This reflexion is based on the model of the positive figure of the possessed from exampla and from dominican hagiography. The treatise therefore aims to counter the tradition of the Episcopi canon which argues for the illusory nature of demons. Instead, it offers an argument about the reality of their actions on the occasion of the sabbat

Interventions présumées des scribes concernant le motif de l'arbre sacré dans le Pentateuque

Abstract: This article deals with several presumed scribal interventions which all concern the sacred tree motif. One finds deliberate changes in the MT, in the Septuagint, in Targum Onkelos and in the Vulgate. The Greek translators of Genesis and Samuel (1-2 Kingdoms) avoided rendering the word אשׁל "tamarisk" by its equivalent μυρίκη, chosing instead the word ἄρουρα "field". Similarly, the Greek translator of Genesis, in the passage of the death of Rebecca's nurse Deborah, passed over the motif of her burial under a grand tree. According to the hypothesis of the present article, all four changes are related to one other; they might be due to the translator's fear to connect the respective texts with traditions and customs concerning the Egyptian god Osiris. On the other side, a scribe of the proto-Massoretic tradition modified the readings mentioning the large tree of Mamre close to Hebron. By changing the noun's number from singular to plural the corrector tried to conceal the existence and importance of the sacred tree in the tradition of Abraham. By contrast, the scribe did not modify texts related to the sacred tree of Shechem. This disparity of treatment may be explained by the fact that, in the view of the Judean scribe, the tree of Shechem would put the Samaritans in a bad light. Finally, the authors of Targum Onkelos and of the Vulgate intervened almost systematically in Pentateuchal texts having the terms אֵלוֹן) אלון or אַלּוֹן ), which always designate a holy tree. The two expressions are rendered by terms referring to plains (Targum Onkelos) or a valley (Vulgate).
