Antennes universitaires : quels effets sur les parcours étudiants ? Le cas de la filière AES au Creusot (71)
2009
09026; Suite à l'« explosion » des effectifs universitaires, de nombreuses antennes ont vu le jour à la fin des années 1980. Il convient maintenant d'évaluer leurs effets sur les parcours étudiants. Notre recherche porte sur la filière AES au sein de l'université de Bourgogne. Dans cet article, nous comparerons successivement le recrutement, la réussite en DEUG et le parcours ultérieur des étudiants de l'antenne du Creusot par rapport à ceux de l'université centrale de Dijon. Nous verrons que l'antenne permet une ouverture sociale au niveau du recrutement, que la réussite y est un peu meilleure et que les parcours ultérieurs ne diffèrent pas entre les deux publics étudiants.
The influence of financial features and country characteristics on B2B ICOs’ website traffic
2021
Abstract Technology, blockchain, and initial coin offerings (ICOs) have changed the established ways of financing companies and doing business. The changes that affect organizational communications, specifically marketing communications, remain unclear, especially in the context of business-to-business (B2B) organizations. The current trend is for B2B companies to view social media as an optimal way to enhance lasting and valuable relationships with other companies. There is little research on social media marketing strategies by B2B organizations. To fill this gap, this study uses a sample of 57 B2B ICOs completed by December 2019 and qualitative comparative analysis to examine how the com…
Extreme value theory versus traditional GARCH approaches applied to financial data: a comparative evaluation
2013
Although stock prices fluctuate, the variations are relatively small and are frequently assumed to be normally distributed on a large time scale. But sometimes these fluctuations can become determinant, especially when unforeseen large drops in asset prices are observed that could result in huge losses or even in market crashes. The evidence shows that these events happen far more often than would be expected under the generalised assumption of normally distributed financial returns. Thus it is crucial to model distribution tails properly so as to be able to predict the frequency and magnitude of extreme stock price returns. In this paper we follow the approach suggested by McNeil and Frey …
International experiences in whole of government financial reporting: lesson-drawing for Spain
2009
This article focuses on whole of government accounts from a comparative perspective and identifies key lessons for Spain and other European countries with a continental accounting system. The authors examine the issues involved in whole of government financial reporting in New Zealand, Australia, the UK and North America. They conclude that whole public sector consolidated accounts are not currently feasible in Spain and that consolidation should start at each level of government.
Behavior adaptation and selection.
2010
6 pages; The evolutionary approach to behavior is concerned with the evolutionary origin and adaptive function of behavioral traits. Like any other part of the phenotype, behavior can be shaped by natural selection to produce adaptations. However, behavior often shows large phenotypic variation and flexibility, and can be both – subject to selection and a major agent of selection. Therefore, the study of adaptation and evolution of behavior is a particularly complex one, involving a wide range of methodologies and techniques, including mathematical modeling, comparative methods, phenotypic engineering, quantitative genetics, genetic dissection, and artificial selection.
TESTING SIMILARITY COEFFICIENTS FOR ANALYSIS OF THE FOSSIL RECORD USING CLUSTERING METHODS: THE PALAEOZOIC FLORA AS A STUDY CASE
2020
This paper reports a global methodological approach based on the similarity and clustering methods of the Palaeozoic plant fossil record using a comparative approach between two similarity measures: the Jacard and Raup-Crick Coefficients. The results show that although the Raup-Crick Coefficients clearly have the potential for providing more robust results, the consequences of the extinction processes are better reflected in the similarity analysis based on the Jaccard Coefficients. On the other hand, the cluster analysis based on UPGMA algorithm shows four robust clusters and reveals new evidence for the singularity of Mississippian flora. Finally, the results obtained reveal that similari…
Analysis of the bryophyte diversity of mountain ranges in Sicily.
2015
The focus of this study was an analysis of the bryophyte flora of the main Sicilian mountain ranges, i.e., Peloritani, Nebrodi and Madonie mountains, located along the northern side of the Island, the Sicani mountains, located in the west-central Sicily and the Etna, the highest and most active volcano of Europe. The overall bryoflora consists of 504 taxa, 400 mosses and 104 liverworts and hornworts. It represent the 85.3% of the whole Sicilian flora; the mosses are referred to 37 families, the liverworts together with hornworts to 31 families. The phytogeographical analysis has shown the prevalence of the Mediterranean species, with the highest value on the Sicani mountains. It is notewort…

Perioperative and anesthetic deaths: toxicological and medico legal aspects
2019
Abstract Background Anesthesia has become safer during decades, though there is still a preventable mortality; the complexity of medical and surgical interventions, increasingly older and sicker patients, has created a host of new hazards in anesthesiology. In this paper, some of these perioperative (PO) fatal adverse events are investigated in terms of health responsibility. Selective literature research in several data bases, concerning perioperative and anesthetic deaths and medical responsibility, was performed. Main text A generally accepted definition of the anesthesia and perioperatory-related death still remains one of the major concerns in forensic pathology, and the terms “operati…
Initiation of the professional development of the teachers of primary (Argentine, Colombia, Spain and France). Comparative study.
2016
espanolUno de los aspectos fundamentales en la consecucion de una educacion de calidad es la figura del maestro, su formacion y su forma de intervenir en las aulas de educacion primaria en tanto en cuanto la profesionalidad de los docentes puede marcar la diferencia en el aprendizaje de los estudiantes incluso contrarrestando las dificultades de origen. De hecho: �Las escuelas que desafian sus condiciones adversas y logran buenos resultados de aprendizaje son aquellas en las que los docentes han asumido una mayor participacion en la toma de decisiones institucionales y un mayor compromiso con los resultados de aprendizaje de los alumnos (OREALC/ UNESCO, 2007, p.60)�. Por todo ello, desde es…
