Caractéristiques socio-écologiques de la classe et comportements scolaires des écoliers
2013
Ce travail porte sur les déterminants socio-écologiques des comportements des écoliers dont les réactions envers la classe, la formation de l'amitié, l'estime de soi scolaire, la performance ainsi que " l'anxiété et le stress scolaires (N = 25 classes). Les dimensions du climat social de la classe jouent un rôle intermédiaire dans le mécanisme d'influence, à la fois comme variables dépendantes des caractéristiques physico-environnementales et variables explicatives des comportements. Cette étude suggère d'orienter le climat de la classe vers les domaines relatifs aux relations interpersonnelles, au développement personnel et au maintien du système de la classe. Le premier domaine est partic…
Déterminants personnels des compétences de l'écolier : le cas de sa performance scolaire et de ses réactions envers la classe
2012
Ce travail porte sur les déterminants personnels de deux types de compétences chez l'élève : celles d'ordre cognitif (soit sa performance scolaire) et les compétences relevant du savoir-être (ou de ses réactions envers la classe). Les recherches sur les compétences cognitives n'ont souvent porté, malheureusement, que sur l'étude de simples associations entre certaines variables personnelles et la performance scolaire. Elles n'ont pas tenté de saisir, dans un modèle théorique, les mécanismes dynamiques par lesquels la personnalité de l'élève influe sur sa performance. Une telle approche conduit à une compréhension superficielle de cette dernière. Force est de constater par ailleurs qu'aucune…

The importance of the Logistics Performance Index in international trade
2014
Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) analyses differences between countries in terms of customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. The aim of this article is to analyse the impact that each of these components has on trade in emerging economies using a gravity model. Furthermore, the study also attempts to detect possible advances in logistics in developing countries, which are grouped into five regions (Africa, South America, Far East, Middle East and Eastern Europe) by comparing the first LPI data published in 2007 with the most re…
Asphalt mixtures improved with plastic additives: mix design and case study in an airport
La crescente domanda di prestazioni e le esigenze di salvaguardia dell’ecosistema spingono a sviluppare nuove tecnologie di lavorazione, a sperimentare l’impiego di nuovi materiali, a migliorare i metodi di progetto delle miscele. Il criterio seguito è quello di un impiego più razionale delle risorse e dell’utilizzo di tecniche a basso impatto ambientale. Per ragioni tecniche ed economiche stiamo assistendo al fenomeno di espansione nel mercato degli additivi, impiegati nella produzione di miscele bituminose per migliorarne le prestazioni e ridurre i costi. In generale, però riuscire a soddisfare tutti gli obiettivi con un unico prodotto è difficile, perché l’alta qualità richiede costi più…
An Exploratory Study of Financial Performance in CEE Countries
2020
Our research investigates the performance of companies from Central and Eastern European (CEE) countries in the period after the Global Financial Crisis of 2007-2009 with the aim of identifying the driving factors behind accounting- and market-based performance. We include in the analysis companies from various industries in CEE countries that are European Union members and we study their performance between 2008-2016 over the following areas of performance: liquidity, solvency and indebtedness, operational profitability, global performance (through Return on assets and Return on equity), returns available to shareholders and market-based performance (through price/book value and Tobin Q …
2-Deoxyecdysone is a circulating ecdysteroid in the beetle Zophobas atratus
1997
A qualitative analysis of ecdysteroids has been performed during the post-embryonic development of the tenebrionid beetle, Zophobas atratus, by high performance liquid chromatography (HPLC) combined with enzyme immunoassay (EIA) using two different antibodies. Three HPLC peaks were found to be immunoreactive, in hemolymph extracts of both sexes. Moreover, these peaks had ecdysteroid-like UV spectra, determined using a photodiode array detector. The use of two different HPLC systems (reverse and normal phases), in combination with two different EIA antibodies, allowed us to identify 20-hydroxyecdysone (20E) and ecdysone (E), as the two main ecdysteroids, but also suggested the presence of 2-…
Assessing the sustainability of water companies: A synthetic indicator approach
2016
Performance indicators (PIs) are essential in the benchmarking process used to rate and rank water companies. However, a set of individual PIs does not provide a holistic assessment of company performance from multiple perspectives. A multidimensional evaluation of the performance of water companies can be achieved by aggregating the PIs into a synthetic indicator. Although the concept of sustainability involves economic, environmental and social criteria, most of the previous studies have not considered these three dimensions simultaneously. This paper discusses a process of indicator aggregation using two approaches based on multi-criteria decision analysis to evaluate and compare the sus…
Chronic Background Radiation Correlates With Sperm Swimming Endurance in Bank Voles From Chernobyl
2022
Sperm quantity and quality are key features explaining intra- and interspecific variation in male reproductive success. Spermatogenesis is sensitive to ionizing radiation and laboratory studies investigating acute effects of ionizing radiation have indeed found negative effects of radiation on sperm quantity and quality. In nature, levels of natural background radiation vary dramatically, and chronic effects of low-level background radiation exposure on spermatogenesis are poorly understood. The Chernobyl region offers a unique research opportunity for investigating effects of chronic low-level ionizing radiation on reproductive properties of wild organisms. We captured male bank voles (Myo…
