[en] The European project was a promise for the peoples of Europe to take up together the technological, economic and scientific challenges that each nation could not face alone. Alas, the beautiful dream of European cooperation repeating the successes of Ariane or Airbus has crashed against the Europeanist bureaucracy and the impotent ideology of the European Treaties, which it zealously applies

[en] The conventional education system that is a teacher-oriented is not defining and achieving the expected learning outcomes of the engineering students in Pakistan. Being the full signatory of the Washington Accord, Pakistan Engineering Council (PEC) declared the implementation of OBE system compulsory for the engineering institutes to get accreditation. Many public and private institutes are yet hesitant to adopt and implement the OBE system due to its dynamic approach and built-in complexity. This paper presents the implementation of the outcome-based education system in the department of electrical engineering, Riphah International University, as a case study. However, the approach is to highlight and meet the major requirements for any engineering program. The OBE system was successfully implemented to meet the university mission and vision through Program Educational Objectives (PEOs), Program Learning Outcomes (PLOs) and the Course Learning Outcomes (CLOs) through a well-defined and certain approach. This paper will be a guideline for the public and private institutes in Pakistan, inclined to implement the OBE system under the Washington accord signatory of Pakistan Engineering Council. (author)
[en] The relationship between diversity and productivity of plant community under plant invasion has been not well known up to now. Here, we investigated the relationship between diversity and productivity under plant invasion and studied the response of species level plant mass to species richness in native and invaded communities. A field experiment from 2008 to 2013 and a pot experiment in 2014 were conducted to study the effects of plant invasion on the relationship between diversity and productivity and the response of species level plant mass to species richness in native and invaded communities. The community level biomass was negatively correlated to plant species richness in invaded communities while the same relationship was positive in native communities. The species level plant mass of individual species responded differently to overall plant species richness in the native and invaded communities, namely, most of the species’ plant mass increased in native communities, but decreased in invaded communities with increasing species richness. The complementarity or selection effects might dominate in native communities while competition effects might dominate in invaded communities. Accordingly, the negative relationship between diversity and productivity under plant invasion is highlighted in our experiments.
[en] To identify the main drivers that facilitate the successful deployment of a participation program aimed at improving competitiveness, as a prior step to analyze and discuss the implementation of these drivers in three services companies. Design/methodology/approach: The selection of the drivers was based on a “content analysis” of recent literature (2007-2017). To test the level of deployment of these drivers, the “case study” technique was chosen. The authors have selected two public transport companies and one bank, which have more than twenty years’ experience in the development of participation programs. From the case studies analysis, we conclude that participation can successfully improve a company’s competitiveness, provided that the drivers are developed with this specific aim. Thus, the analysis of these drivers allows to identify some gaps in aspects such as, the extension of participation throughout the company, the methodology adopted in the deployment of participation programs, the organizational structure for monitoring the program tasks, the reward/recognition systems and, especially, the implementation of KPIs for connecting participation and competitiveness.This paper is based on a review of current literature, the analysis of three case studies, and our own personal experience. Our observations and comments may be qualified by future investigation with an increased sample of companies. Practical implications: This paper could be of interest to companies due to outlines the drivers that are critical to implementing participation programs focused on competitiveness. This could help companies that are thinking of implementing such programs, or those that are unhappy with their current programs, to re-design their plans in line with their business strategy. Originality/value: The main contribution of this paper lies in its theoretical and applied approach, analyzing in a comparative and longitudinal way the deployment of the drivers in services companies. This analysis allows the identification of strengths and weaknesses in the implementation of these participation programs focused on competitiveness. This combined and comparative approach is considered especially novel in the academic and profesional world. Likewise, the analysis of companies with a longstanding history in their participation programs is also relevant, particularly, in the services sector.
[en] Based on the comprehensive analysis and research, this paper summarizes the present situation and existing problems of nuclear safety equipment bidding, analyzes the causes and points out the influence and harm of unreasonable low price bid winning, put forward four proposals involve purchaser, nuclear equipment licensee, the competent department of nuclear power, the nuclear safety regulatory authority to prevent unreasonable low price bid winning.

[en] In this paper, the dynamics of a discrete market share attraction model are investigated. It shows that the system can undergo flip bifurcation and chaos. The stability and bifurcation of a market share attraction model are analyzed by using the bifurcation theory and the center manifold theorem. The system displays complex dynamical behaviors, including period-1, 2, 4, 6, 8, 16 orbits, invariant cycle, a cascade of period-doubling, quasi-periodic orbits, and the chaotic sets. Numerical simulations illustrate the analysis and results.
[en] This article provides an overview of Mexico's energy sector, together with a number of general characteristics. Current and future developments in the oil, natural gas and electricity sectors are discussed, demonstrating the broad scope of the Mexican energy system and highlighting past trends. Based on these data, the article describes and analyses the initial results of the reforms undertaken in 2013-2014, which encompass all energy industries. The opening up to competition of the oil and gas industry, as well as the electricity system, has led to a re-organisation of the energy sector. However, the situation has been rendered uncertain with the arrival of a new government on 1 December 2018
[fr]Cet article presente une description du secteur de l'energie au Mexique et quelques caracteristiques generales. Les evolutions actuelles et futures des secteurs du petrole, du gaz naturel et de l'electricite sont abordees, montrant l'etendue du systeme energetique mexicain. Cette presentation evoque egalement certaines tendances passees. A partir de ces donnees, l'article analyse les caracteristiques et les premiers resultats des reformes entreprises en 2013/2014, qui englobent toutes les industries de l'energie. Depuis l'ouverture a la concurrence de la chaine des hydrocarbures et du systeme electrique, on assiste a l'emergence d'une nouvelle organisation du secteur de l'energie. Cependant, des incertitudes ont ete introduites avec l'arrivee d'une nouvelle administration gouvernementale, le 1er decembre 2018
[en] The issue of energy sums up and illustrates most of the ills that plague society: inequalities in access to energy; private ownership of the means of production and distribution of energy; a mixture of monopolies and competition that never benefits households but yields shameless annual profits for shareholders; and ever-increasing threats to resources and the environment
[fr]La question de l'energie resume et illustre la plupart des maux qui gangrenent la societe: inegalites dans l'acces a l'energie; propriete privee des moyens de production et de distribution de l'energie; melange de monopoles et de concurrence qui ne profite jamais aux menages mais qui permettent de degager des profits annuels ehontes pour les actionnaires; menaces de plus en plus lourdes sur les ressources et l'environnement
[en] The liberalisation of Europe's electricity sector has been based on the principle of competition 'by' the market. Another option would have been to favour competition 'for' the market. After this market wave, Europe underwent a 'green wave' that promoted renewables through off-market subsidies, thereby introducing many exceptions to the principle of competition, exceptions that have somewhat blurred the underlying message. This dual wave is the focus of the article
[fr]La liberalisation du secteur de l'electricite s'est appuyee en Europe sur le principe de la concurrence 'par' le marche. Une autre option aurait ete de privilegier la concurrence 'pour' le marche. Apres cette vague du marche, l'Europe a connu une 'vague verte' qui, en en favorisant la promotion des renouvelables par des aides hors marche, a introduit de nombreuses exceptions au principe de la concurrence, ce qui a quelque peu brouille les messages. C'est cette double vague que retrace cet article
