Semi-strong inefficiency in the fixed odds betting market: Underestimating the positive impact of head coach replacement in the main European soccer …
2019
Abstract In this paper we analyse the efficiency of the sports betting market, seeking to ascertain whether the market is efficient in the case of fixed odds provided by bookmakers in the four major European soccer leagues under the semi-strong efficiency hypothesis. By examining the trends of odds in the event of a major change in expectations about team results, i.e. when the head coach of a team is replaced, we attempt to verify the argument that a profitable strategy for the bettor is likely to be possible. In this case, the market under consideration would be inefficient. Analysing the average effect of head coach replacement, we find a positive impact on team performance. Based on thi…
Agricultural externalities and environmental regulation: evaluating good practice in citrus production
2006
Economic activity takes place in a scenario characterized by an increasing number of environmental regulations aimed at bringing under control the emission of contaminating wastes. In this paper, we evaluate the impact of transforming a code of good practice in nitrogen fertilization on Spanish citrus fruit farms into an environmental regulation of compulsory fulfilment. Using data envelopment techniques, we calculate unrestricted and environmentally regulated short-run maximum profits. Both profit values are then used to compute an index of the cost of regulation. Our results suggest that the cost of shifting from a merely recommended practice to a binding rule is low. On average, the loss…
Assessment of Sustainable Well-being in the Italian Regions: An Activity Analysis Model
2018
Applying the theoretical framework of productive analysis, the paper proposes an evaluation of regional sustainable well-being (SWB) in terms of efficiency. By means of an Activity Analysis Model (AA) (Fare et al., 1996), desirable and undesirable outcomes of development have been simultaneously used to evaluate the sustainable well-being of Italian regions. Data on equal and sustainable well-being provided by the Italian Statistical Office for the year 2010 has been used. The analysis reveals that only four regions achieve sustainable well-being, balancing socio-economic and environmental outcomes and resources. Finally, the study points out the advantages of AA for policy purposes by comp…
Efficiency of French privatizations: a dynamic vision
2004
The program of French privatizations is one of the principal worldwide programs as for the volume of the equity issues. A reading of the process of privatization through the corporate governance theory resulted in working out a model making it possible to take into account, on the one hand, the time dimension of the process of privatization, on the other hand, the contextual, organizational, governance and strategic variables which influence this process. After having replicated a certain number of traditional tests, we carried out a test of this model on a sample of 19 French privatized firms and on a seven years horizon, which made it possible to obtain the following conclusions. The favo…
Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā
2014
ANOTĀCIJA Promocijas darba „Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā” mērķis ir izpētīt mācīšanās rezultātu nozīmi profesionālajā vidējā izglītībā un noskaidrot, kā notiek pāreja uz mācīšanās rezultātos balstītu izglītības procesu. Pētījuma ietvaros tika veikta profesionālās izglītības iestāžu audzēkņu aptauja, skolotāju un darba devēju intervijas. Pētījumā secināts, ka skolotāji un darba devēji neizprot mācīšanās rezultātu lomu profesionālajā izglītībā. Skaidri formulēti mācīšanās rezultāti profesionālās izglītības programmās sniedz precīzu informāciju par mācību procesu un tā iznākumu visām iesaistītajām pusēm, līdz ar to vairāk jauniešu var izvēlēties profesionā…
Fog Computing based traffic Safety for Connected Vulnerable Road Users
2019
Annually, millions of people die and many more sustain non-fatal injuries because of road traffic crashes. Despite multitude of countermeasures, the number of causalities and disabilities owing to traffic accidents are increasing each year causing grinding social, economic, and health problems. Due to their high volume and lack of protective-shells, more than half of road traffic deaths are imputed to vulnerable road users (VRUs): pedestrians, cyclists and motorcyclists. Mobile devices combined with fog computing can provide feasible solutions to protect VRUs by predicting collusions and warning users of an imminent traffic accident. Mobile devices’ ubiquity and high computational capabilit…
L'Impact des programmes de formation continue sur les compétences professionnelles des enseignants dans le contexte éducatif syrien (cas de l'enseign…
2014
As in nearly all countries, educational authorities in Syria have concerns about improving the quality of education and about there forms they seek to implement to give teachers the opportunity to acquire new knowledge and skills before and once they start teaching, especially in the context of economic and social change of the magnitude the world lives today. The complexity of the educational context has led the Syrian educational authorities to pay particular attention to programs for initial and continuous training of teachers. To assess the effectiveness of continuous training programs that currently exist in Syria, this thesis has set as its objective to analyze the impact of these pro…
La contribution de l'éducation à la croissance économique du Sénégal
2013
The aim of this work is to show that education contributes to economic growth, that is to say that there is a relationship between the variables of education and economic growth in Senegal. There are several studies that have examined the relationship between education and economic growth microeconomic point of view, as well as macroeconomic, both theoretically and empirically. Empirical studies that have been done around the world, do not agree on the fact that education has a positive effect on economic growth. This ambiguity has led us to participate in the debate by testing the impact and effectiveness of education on productivity Senegalese companies. This last play an important part i…
Control and design for efficiency improvement of permanent-magnet synchronous motor drives in household appliances
2011
This paper deals with some aspects of efficiency improvement of PMSMD (Permanent Magnet Synchronous Motor Drives). Particularly two aspects are focused: the control algorithm for the PMSMD, which allows to reduce the power losses of the electric drive without penalty on its dynamic performances and the optimization of an IPMSM (Interior Permanent Magnet Synchronous Motor) rotor configuration capable to increase the performances in terms of shaft torque production, limiting at the same time the rotor leakage flux. The loss minimization algorithm is here briefly analyzed, a test bed for experimental validation is presented and the data are analyzed. Experimental tests have been performed aimi…
