Pluralité de l’évaluation d’un dispositif institutionnel de réorientation : bilan sur 5 ans à l’université de Bourgogne
2023
Pour accompagner la réflexion sur la réorientation, cette présentation fait le bilan de 5 années du semestre REO, le dispositif institutionnel de réorientation de l’université de Bourgogne en s’appuyant sur les données administratives de l’établissement, les enquêtes annuelles menées auprès des inscrits au dispositif et sur les bilans annuels établis avec l’équipe pédagogique. Après une présentation du dispositif associée à des informations sur la réorientation à l’échelle nationale (statistiques et cartographie originale des dispositifs des universités), elle informe sur les améliorations réalisées à l’issue de chaque bilan annuel (contenu, fonctionnement et information). Elle donne les év…
Measuring Brand Value: The Case of Romanian Public Traded Companies
2018
Abstract Today most of the world's products benefit from a huge success because of a big brand. If in the past this was the case for the luxury industry where the power of branding it's reaching the consumer in the most impactful way. First by the mystery surrounding the brand, then by keeping the consumer as loyal as possible, the result being huge revenues for this brands, for, eg. LVMH, the largest group by revenue. But things are no longer the same, today the power of branding and huge revenues moved to another industry flourished, tech industry, where companies like Apple, Google, Facebook, Amazon, dominate their sectors benefiting from a strong brand name.
Qualité de l'audit : enjeux de l'audit interne et externe pour la gouvernance des organisations
2011
National audience; L'industrialisation des processus d'audit st un processus désormais mature, après voir connu une diffusion progressive depuis ne trentaine d'années. Les normes d'audit traduisent une démarche très standardisée. Pourtant, il existe un besoin grandissant de jugement sur des phénomènes complexes dont la traduction comptable est malaisée ou ambigüe. La qualité de l'audit, qui est principalement appréhendée à travers les deux dimensions d'indépendance et de compétence de l'auditeur, doit désormais intégrer l'exercice du jugement de rauditeur, c'est-à-dire une dimension qui repose certes sur la compétence et l'indépendance mais qui inclut également d'autres paramètres - liés à …
Economic valuation of environmental benefits of removing pharmaceutical and personal care products from WWTP effluents by ozonation.
2013
Continuous release of pharmaceutical and personal care products (PPCPs) present in effluents from wastewater treatment plants (WWTPs) is nowadays leading to the adoption of specific measures within the framework of the Directive 2000/60/EC (Water Framework Directive). The ozonation process, normally employed for drinking water production, has also proven its potential to eliminate PPCPs from secondary effluents in spite of their low concentrations. However, there is a significant drawback related with the costs associated with its implementation. This lack of studies is especially pronounced regarding the economic valuation of the environmental benefits associated to avoid the discharge of …
Monetary valuation of salicylic acid, methylparaben and THCOOH in a Mediterranean coastal wetland through the shadow prices methodology
2018
The presence of pharmaceutical and personal care products and drugs of abuse (PPCPs) in wastewater treatment plants (WWTPs) indicates discharge of the effluent may not be suitable for the ecological balance of water ecosystems, such as wetlands. These PPCPs degrade water quality, considered as an ecosystem service (ES), provoking serious environmental impacts. Assessing the monetary value of PPCPs can be used as a proxy for environmental status of the ES of water quality (ESWQ). Considering PPCPs as non-desirable outputs of WWTPs, the shadow prices methodology has been implemented using directional distance function to measure the environmental avoided cost of removing salicylic acid (SA), …
Shadow prices of emerging pollutants in wastewater treatment plants: Quantification of environmental externalities.
2017
Conventional wastewater treatment plants (WWTPs) are designed to remove mainly the organic matter, nitrogen and phosphorus compounds and suspended solids from wastewater but are not capable of removing chemicals of human origin, such as pharmaceutical and personal care products (PPCPs). The presence of PPCPs in wastewater has environmental effects on the water bodies receiving the WWTP effluents and renders the effluent as unsuitable as a nonconventional water source. Considering PPCPs as non-desirable outputs, the shadow prices methodology has been implemented using the output distance function to measure the environmental benefits of removing five PPCPs (acetaminophen, ibuprofen, naproxen…
The contingent equilibrium during imbalanced volcano tourism demand through fee estimation: An empirical analysis of tourism in Mt. Etna
2022
Volcanic sites can be considered strategic areas for conservation and protection policies, but such policies may involve considerable costs However, not only are volcanic sites often integral to the tourism industry and, hence, of potential significant benefit to local economies in general; entrance fee income from tourists can also contribute to management and conservation costs in particular. Nevertheless, seasonal variations in tourism demand, resulting in over-and under-tourism situations, may impact on both the level of income generated as well as on the sustainability of sites Therefore, based on a case study of Mt Etna in Italy, this study considers establishing appropriate entry fee…
Estimating the environmental and resource costs of leakage in water distribution systems: A shadow price approach.
2016
Water scarcity is one of the main problems faced by many regions in the XXIst century. In this context, the need to reduce leakages from water distribution systems has gained almost universal acceptance. The concept of sustainable economic level of leakage (SELL) has been proposed to internalize the environmental and resource costs within economic level of leakage calculations. However, because these costs are not set by the market, they have not often been calculated. In this paper, the directional-distance function was used to estimate the shadow price of leakages as a proxy of their environmental and resource costs. This is a pioneering approach to the economic valuation of leakage exter…
Technical assessment and evaluation of environmental models and software: Letter to the Editor
2011
International audience; This letter details the collective views of a number of independent researchers on the technical assessment and evaluation of environmental models and software. The purpose is to stimulate debate and initiate action that leads to an improved quality of model development and evaluation, so increasing the capacity for models to have positive outcomes from their use. As such, we emphasize the relationship between the model evaluation process and credibility with stakeholders (including funding agencies) with a view to ensure continued support for modelling efforts. Many journals, including EM&S, publish the results of environmental modelling studies and must judge the w…
Ambienti umidi effimeri e naturalità del paesaggio in Sicilia
2009
I luoghi umidi temporanei sono ambienti acquatici che alternano periodicamente una fase d’invaso ed una fase secca ed ospitano espressive fitocenosi adattate a queste peculiari condizioni. Indagini condotte tra il 2003 ed il 2009 hanno consentito di individuare, in Sicilia, oltre 200 siti, costituiti generalmente da diverse pozze o piccoli stagni. L’estrema fragilità di questi habitat li rende molto vulnerabili a qualunque tipo di alterazione ambientale e pertanto risultano essere indicatori molto sensibili della pressione antropica sul territorio. Infatti, la conservazione di questi biotopi non può prescindere da una corretta gestione del contesto territoriale che li circonda. Il presente …
