Sistema de monitorización en continuo a tiempo real de la concentración de oxígeno durante el batido para la producción de aceite de oliva virgen
2012
During the mechanical extraction process of Virgin Olive Oil (VOO) some important physical phenomena and enzymatic transformations occur which influence the quality of the final product. The control of process parameters is crucial to ensure the quality of VOO, therefore process monitoring and control is a fundamental requirement in the modern VOO processing industry. The present work proposes an innovative Real-Time Monitoring System (RTMS) aimed at continuously measuring the oxygen concentration during the malaxation process in order to establish a correlation with the quality of the final product obtained. This monitoring system is based on an oxygen concentration sensor directly connect…
Internal Public Audit in the Financial Crisis Context
2013
Abstract The financial crisis effects have left their mark on the area of internal audit, but the attention on the responsibility that internal auditors could have in preventing the onset of such a crisis is quite low. Audit plays a vital role in the entities functioning by contributing to economic credibility. In this paper we have presented the role and objectives of internal audit, the organization and activity of internal audit in local government in Romania, the outsourced system and how it helped in preventing and/or managing the economic downturn.
Coordination and profit rate maximization
1995
We study the effects over the coordination between firms of the choice of another objectivefunction for the firm: the profit rate maximization which seems to be closer to business practice than the classical pure profit maximization. After recalling the effect of the new objective function over the optimum (the optimal production is lower), two cases are considered : perfect competition (the price signal disappear), and duopoly-oligopoly (the functions of reactions may vanish). (FR) Nous étudions les effets sur la coordination inter-firmes du choix d'une autre fonction objectif pour la firme: la maximisation du taux de profit qui semble être plus proche de la pratique des affaires que la cl…
The HOTELLING model : contributions and limits (application to the case where strategic variables are localizations and prices)
1991
Ix modèle de H O T E L L I N G a fait l'objet de nombreuses discussions. O n sait en particulier que lorsque le domaine des paramètres de localisation s'élargit et pour des coûts de transport linéaires, le prix d'équilibre en stratégie pure n'existe plus. I æ coût de transport linéaire et les discontinuités desfonctions sont responsables de l'absence d'équilibre. L'objet, de cette étude est de démontrer l'existence d'un équilibre à partir d'un jeu séquentiel. Toutd'abord les firmes choisisent leur localisation en anticipant des prix d'équilibre. Après avoir vérifié que, dans la pratique des affaires, les coûts de transport peuvent être soit de forme concave, soit de forme convexe, on introd…
Configuration optimale des aires de marché et coûts de transport
1991
La théorie des Places Centrales étudiée par LÖSCH (4) et CHRISTALLER (5) a pour objet l'examen et la construction d'un paysage hiérarchisé. Celui-ci est basé sur un système d'aires de marché qui possèdent des configurations précises (hexagonales et carrées principalement). En fait raire de marché correspond à la zone d'influence d'un offreur. LÖSCH (4, p 130) a supposé que la libre entrée de firmes indépendantes localisées sur une plaine où sont situés des demandeurs équidistants entraine une transformation des aires circulaires en aires hexagonales et ainsi une maximisation du nombre de firmes par unité d'aire. HARTWICK (2) examine analytiquement le théorème de LÖSCH concernant les aires d…
A Self-Funding Reward Mechanism for Tax Compliance
2015
We compare in a laboratory experiment two audit-based tax compliance mechanisms that collect fines from those found non-compliant. The mechanisms differ in the way fines are redistributed to individuals who were either not audited or audited and found to be compliant. The first, as is the case in most extant tax systems, does not discriminate between the un-audited and those found compliant. The second targets the redistribution in favor of those found compliant. We find that targeting increases compliance when paying taxes generates a social return. We do not find any increase in compliance in a control treatment where individuals audited and found compliant receive symbolic rewards. It is…

The inconvenience yield of carbon futures
2021
Abstract Since 2009, the European Carbon Futures Market has been in a permanent contango situation that is characterised by systematic negative convenience yields that allow investors to exploit profitable arbitrage opportunities. The objective of this paper is to analyse the possible drivers of these negative convenience yields. Our empirical results indicate that although some carbon trading variables are behind this contango situation, the carbon inconvenience yield is better explained if other financial markets and variables are considered, suggesting a financialization of the European Carbon Futures Market.
Recent Developments in International Investment Law
2016
International investment law remains a fast evolving and vibrant field of law with ongoing and recently-concluded investment treaty negotiations continually altering the status quo. It is a system at a crossroads of reform, generally focused on safeguarding the right of the host state to regulate and on improving the investor-state dispute settlement (ISDS) mechanism. But reform may also come into play in more far-reaching ways and significant changes are likely to see the day in the near future. One such change concerns the institutional architecture of the resolution of investment disputes, with the possible establishment of a permanent investment court and/or the introduction of an appel…
