Nowadays the European Universities are worried about how to adapt higher education to the new European Higher Education Area, as proposed in the Bologna Magna Charta Universitatum of 1998, and signed by 32 European Education Ministers. One of the key points in this higher education reform was the introduction of new Master’s level curricula. These Masters will look for the professional specialization and they will have to be adapted to the specific skills demanded by the society. This paper presents the results from a cooperation project – funded by the AECI (International Cooperation Spanish Agency) and developed between the University of Seville (Spain) and the Catholic University of Asuncion (Paraguay) – by about the planning of a new master’s level curriculum in digital signal processing (DSP) area, taking into account the Bologna principles and the conclusions obtained by the Career Space Consortium. A scientific method from social science, known as concept mapping techniques, was used to perform this planning. Basically, the idea of concept mapping consists of compiling the opinion from actors belonging to different environments (lecturers, researchers, workers, businessmen, etc.) related to DSP applications. The compiled data were statistically computed to cluster the opinions of the different agents. The result will be a master’s level curricula adapted to the environment requirements and the social settings.  相似文献

Direct elite participation in civil wars remains unexplored terrain. It should be analytically telling, because it involves taking major risks and costs. Here, we consider the direct participation of one rural elite—big cattle ranchers—in the Colombian paramilitary saga. We claim that it was massive, locally specific, regulated by institutions, and riddled by permanent collective action issues. We focus on two important forms of direct participation: ranchers as leaders of paramilitary groups, and ranchers as promoters and beneficiaries of coercive land dispossession. This does not cover the full spectrum of potential elite participation in war, but it is a key starting point to sort out the ways in which extreme inequality is associated with political violence from above.  相似文献

Using original survey data collected on growers, traders, processors, markets, and village communities, we will compare the situation in four states: Tamil Nadu, Uttar Pradesh, Maharashtra, and Orissa. We examine the way that information about crop attributes is conveyed (or not) along the value chain. We find that little information circulates about unobservable crop characteristics. Growers receive a price premium when they dry, grade, and pack their produce, but we find no evidence that information about crop salubrity or agricultural practices circulates through the value chain or that growers are encouraged to follow specific agricultural practices for quality purposes. Market infrastructure is deficient regarding sanitation, with few public toilets, inadequate drainage, and no coordinated pest control.  相似文献

Using Mexican data, this article analyzes the impact of the workers' remittances on the cross‐section distribution of prices as well as on the evolution of individual relative prices over time for 272 consumer items. The results suggest that there are important differences in the responses of relative prices to remittances according to various categories of these items. While the relative prices of a number of nontradable service items such as housing consistently rise, the relative prices of several durable items such as furniture tend to fall in response to the remittance shock. Furthermore, remittances explain substantial variation in prices for a large number of consumer durables and services at various time horizons. The relative price responses are more volatile over time for most food items and less volatile for nonfood and service items reflecting different degrees of price flexibility.  相似文献

We conduct a framed field experiment in rural Ethiopia to test the seminal hypothesis that insurance provision induces farmers to take greater, yet profitable, risks. Farmers participated in a game protocol in which they were asked to make a simple decision: whether or not to purchase fertilizer and if so, how many bags. The return to fertilizer was dependent on a stochastic weather draw made in each round of the game. In later rounds a random selection of farmers made this decision in the presence of a stylized weather-index insurance contract. Insurance was found to have some positive effect on fertilizer purchases. Purchases were also found to depend on the realization of the weather in the previous round. We explore the mechanisms of this relationship and find that it may be the result of both changes in wealth weather brings about, and changes in perceptions of the costs and benefits to fertilizer purchases.  相似文献

Is the purpose of this speech to build in an eclectic and holistic way the bases of a theoretical mark that it describes, analyze and do interpret the phenomenon of the managerial entrepreneurship from the interdisciplinary point of view in such a way that the foundation is to respond to the question how to understand the entrepreneurship?, to build starting from their evolution diverse perspectives that you/they enrich their analysis and study that make understand that the entrepreneurship is a practical, simple and complex phenomenon that the managers experience directly in their activities and functions, as a breaking act and improvement of the conditions of life of the society. It is sought to analyze and to propose perspectives of study of the entrepreneurship of the managers, their personal characteristics, as their social, political, economic and cultural implications, from the interdisciplinary point of view in the mark of the investigation line entrepreneurship and Managerial Mentality that he/she interprets their purpose action, administration, innovation and mainly their relationship with the environment, so momentous for the growth of the companies.  相似文献

We focus on the role of the state in land dispossession during war. State agencies promote land accumulation not only through coercive paths, but also by combining political and market mechanisms. Each mechanism may link the state with different actors and coalitions. We illustrate how this worked in Tibú, a Colombian municipality in which violence against civilians and land accumulation took place in more or less distinct phases. The case highlights the fact that land accumulation during war is not only achieved through coercion. At the same time, it shows the importance of identifying the specific coalitions through which states establish their presence in contested territories during war. We explain such variation as resulting from the types of alliances and coalitions that the state establishes with different sets of stakeholders, and the aims pursued by coalition actors.  相似文献

The criticisms of Utility Theory focus on either its axioms or the construction of utility functions. Here we present a method which avoids the problems of uniqueness encountered in the construction of utility functions when using either the certainty equivalence method or the probability equivalence method. The method is based on the construction of ratio scale value functions from reciprocal pairwise comparisons and Saaty's Eigenvector Method. We show that under the assumption of cardinal consistency utility functions are a particular case of these ratio scales. Reciprocal pairwise comparisons allow decision makers to relax the transitivity assumption and help to derive a unique scaling of preferences.  相似文献

This article presents the evaluation of a group of six suppliers for an electromechanical component of hydraulic bombs. The comparison is made by using the dimensional analysis technique and the attributes evaluated were the component´s costs, product quality, post sale service from supplier, product reliability, supplier’s administration and organization and production technology in their production system. In addition, in order to integrate the opinion of several persons in the selection and decision process, the information analysis was done with the aid of a decision group integrated by five persons with responsibilities in the purchase area. The technique is easy to apply and has been widely accepted by its users, who are making its use extensive to other components supplier’s selection process.  相似文献
