The Integrated Mass Transit Systems Program in Colombia: an Example of Recentralization of the Cities´ Management?

The Integrated Mass Transit Systems are an initiative of the Colombian Government to replicate the experience of Bogota’s Bus Rapid Transit System —Transmilenio— in large urban areas of the country, most of them over municipal perimeters to provide transportation services to areas undergoing a metropolization process. Management of these large scale metropolitan infrastructure projects involves complex setups that present new challenges in the interaction between stakeholders and interests between municipalities, tiers of government and public and private sectors. This article presents a compilation of the management process of these projects from the national context, based on a document review of the regulatory framework, complemented by interviews with key stakeholders at the national level. Research suggests that the implementation of large-scale metropolitan projects requires a management framework orientated to overcome the traditional tensions between centralism and municipal autonomy.

Stock return comovements and integration within the Latin American integrated market

Financial integration has been pursued aggressively across the globe in the last fifty years; however, there is no conclusive evidence on the diversification gains (or losses) of such efforts. These gains (or losses) are related to the degree of comovements and synchronization among increasingly integrated global markets. We quantify the degree of comovements within the integrated Latin American market (MILA). We use dynamic correlation models to quantify comovements across securities as well as a direct integration measure. Our results show an increase in comovements when we look at the country indexes, however, the increase in the trend of correlation is previous to the institutional efforts to establish an integrated market in the region. On the other hand, when we look at sector indexes and an integration measure, we find a decreased in comovements among a representative sample of securities form the integrated market.

Análisis diacrónico de la producción española de tesis doctorales en educación matemática mediante la metodología ARIMA (Auto-Regressive Integrated Moving Average) en datos de diseños longitudinales.

Se analiza la manera en que se realizan las tesis doctorales en educación matemática en España. Se utiliza la metodología ARIMA (Auto-Regressive Integrated Moving Average) para realizar el análisis de manera diacrónica sobre datos longitudinales. Se hace incapié en la importancia de la metodología usada y sus ventajas frente a las metodologías tradicionalmente usadas en análisis diacrónicos. Se exponen las cuatro fases de la metodología ARIMA, correspondientes a la identificación del proceso, la estimación de cambio en el proceso, la validación del mismo y la predicción de sus consecuencias.

Este texto proporciona detallados consejos prácticos y sugerencias para los educadores de escuelas pertenecientes a comunidades muy diversas, culturalmente y lingüísticamente. Algunos capítulos se centran en las necesidades de los estudiantes de comunidades de inmigrantes, especialmente los que están aprendiendo la lengua de enseñanza, aunque también se incluyen otros grupos minoritarios.

Uncovering CLIL : Content and Language Integrated Learning in Bilingual and Multilingual Education.

Una guía para los profesores de idiomas con diferentes metodologías y técnicas utilizadas en la enseñanza del Aprendizaje Integrado de Conocimientos Curriculares y Lengua Extranjera (AICLE). Ofrece ideas y sugerencias prácticas sobre lo que funciona en el aula, explicaciones y ejemplos de cómo utilizar AICLE en la enseñanza primaria, secundaria y profesional para contribuir a conseguir el plurilingüismo.

CLIL : content and language integrated learning.

Los autores se basan en su experiencia en las escuelas secundarias, escuelas primarias y escuelas de idioma inglés en toda Europa para ofrecer una visión global de Content and Language Integral Learning (CLIL). Se resume la teoría que sustenta la enseñanza de una asignatura a través de otro idioma y se discute su aplicación práctica, destacando los ejes importantes para el desarrollo de la investigación y la práctica. Reconocen la incertidumbre que muchos docentes sienten sobre el CLIL, debido a la exigencia del lenguaje y conocimiento de la materia, al tiempo que presentan rutas teóricas y prácticas con éxito para todos.

DAI-DEPUR: an integrated and distributed architecture for wastewater treatment plants supervision

The activated sludge process - the main biological technology usually applied to wastewater treatment plants (WWTP) - directly depends on live beings (microorganisms), and therefore on unforeseen changes produced by them. It could be possible to get a good plant operation if the supervisory control system is able to react to the changes and deviations in the system and can take the necessary actions to restore the system’s performance. These decisions are often based both on physical, chemical, microbiological principles (suitable to be modelled by conventional control algorithms) and on some knowledge (suitable to be modelled by knowledge-based systems). But one of the key problems in knowledge-based control systems design is the development of an architecture able to manage efficiently the different elements of the process (integrated architecture), to learn from previous cases (spec@c experimental knowledge) and to acquire the domain knowledge (general expert knowledge). These problems increase when the process belongs to an ill-structured domain and is composed of several complex operational units. Therefore, an integrated and distributed AI architecture seems to be a good choice. This paper proposes an integrated and distributed supervisory multi-level architecture for the supervision of WWTP, that overcomes some of the main troubles of classical control techniques and those of knowledge-based systems applied to real world systems

Development of a decision support system for the integrated control of membrane bioreactors

The work presented in this PhD thesis includes various partial studies aimed at developing a decision support system for membrane bioreactor integrated control. The decision support systems (DSS) have as a main goal to facilitate the operation of complex processes due to the multiple variables that are processed. For this reason, the research used has focused on aspects related to nutrient removal, and on the development of indicators or sensors capable of facilitating, automating and controlling the filtration process in an integrated way with the biological processes that taking place. Work has also been done on the design, development, implementation and validation of tools based on the knowledge made available by the automatic control and the supervision of the MBRs

Integrated management of urban wastewater systems: a model-based approach

The main objective pursued in this thesis targets the development and systematization of a methodology that allows addressing management problems in the dynamic operation of Urban Wastewater Systems. The proposed methodology will suggest operational strategies that can improve the overall performance of the system under certain problematic situations through a model-based approach. The proposed methodology has three main steps: The first step includes the characterization and modeling of the case-study, the definition of scenarios, the evaluation criteria and the operational settings that can be manipulated to improve the system’s performance. In the second step, Monte Carlo simulations are launched to evaluate how the system performs for a wide range of operational settings combinations, and a global sensitivity analysis is conducted to rank the most influential operational settings. Finally, the third step consists on a screening methodology applying a multi-criteria analysis to select the best combinations of operational settings.
