En este trabajo se analizan las fuentes de las que procede la creciente competencia a la que se están viendo sometidas las universidades públicas españolas y que están transformando de forma sustancial el entorno en el que se desenvuelve su actividad. Ante estos cambios se destaca la necesidad de que la universidad pública se adapte a las nuevas condiciones del entorno orientando su oferta formativa a las nuevas necesidades y demandas sociales. Para ello se sugiere la adopción de los planteamientos teóricos de la orientación al mercado que, si bien fueron inicialmente desarrollados para guiar el comportamiento de organizaciones que operan en mercados competitivos, durante los últimos años han mostrado una gran eficacia al ser aplicados a instituciones públicas u organizaciones no lucrativas.

Thus, it is usual to design a resonant converter to include

Such complacency is not justified. In estimating necessary levels of risk capital, the primary concern should be to address those disturbances that occasionally do stress institutional solvency-the negative tail of the loss distribution that is so central to modern risk management. As such, the incorporation of stress scenarios into formal risk modeling would seem to be of first-order importance. However, the incipient art of stress testing has yet to find formalization and uniformity across banks and securities dealers. At present, most banks pick a small number of ad hoc scenarios as their stress tests. And although the results of the stress tests may be given to management, they are, to my knowledge, never entered into the formal risk modeling process." -Alan Greenspan [2000] W hile VaR models have proven themselves to be very useful risk management tools, recent financial debacles have also highlighted their limitations-in particular, their excessive dependency on history or unrealistic statistical assumptions. The natural response to these limitations is for firms to resort to stress tests to complement the results of their VaR analyses. Stress tests are exercises to determine the losses that might occur under unlikely but plausible circumstances, and there has been a dramatic increase in the importance given to stress testing since the east Asian crisis and the LTCM affair. Indeed, many firms and regulators now regard stress tests as no less important than VaR methods for assessing a firm's risk exposure.

To do that, an algorithm of computing boundary genes of a cluster is presented. After applying this algorithm, it is possible to build 3D cluster surfaces.

This option's payoff is a function of time-dependent power and fuel prices, as well as the heat rate and the costs of running the facility. Indeed this approach allows one to obtain quick, ballpark estimates for the financial payoff of a generation asset. However, this simplistic approach avoids several key components that can adversely effect the operation and risk- management of the power plant. With the abundance of raw data and the speed of modern computation, the task of more accurately simulating the details of the contract can be addressed. Incorporation of Weather While the traditional approach implicitly incorporates weather via seasonality in the forward price curve of fuel and power, a more realistic model will treat weather as a fundamental stochastic driver. In this way, we can model...

Data from the Web is becoming increasingly more important as sources for these systems, which has motivated the extensive use of XML to facilitate data and metadata interchange among heterogeneous data sources from the Web and the data warehouse. However, the business information that data warehouses manage is highly sensitive and must, therefore, be carefully protected. Security is thus a key issue in the design of data warehouses, regardless of the implementation technology. It is important to note that the idiosyncrasy of the unstructured and semi-structured data requires particular security rules that have been specifically tailored to these systems in order to permit their particularities to be captured correctly. Unfortunately, although security issues have been considered in the development of traditional data warehouses, current research lacks approaches with which to consider security when the target platform is based on XML technology. Objective: We shall focus on defining transformations to obtain a secure XML Schema from the conceptual multidimensional model of a data warehouse. Method: We have first defined the rationale behind the transformation rules and how they have been developed in natural language, and we have then established them clearly and formally by using the QVT language. Finally, in order to validate our proposal we have carried out a case study. Results: We have proposed an approach for the model driven development of Secure XML Data Warehouses, defining a set of QVT transformation rules. Conclusion: The main benefit of our proposal is that it is possible to model security requirements together with the conceptual model of the data warehouse during the early stages of a project, and automatically obtain the corresponding implementation for XML.
