The history of technology in education. A comparative study and forecast

Area, launched in 1999 with the Bologna Declaration, has bestowed such a magnitude and unprecedented agility to the transformation process undertaken by European universities. However, the change has been more profound and drastic with regards to the use of new technologies both inside and outside the classroom. This article focuses on the study and analysis of the technology’s history within the university education and its impact on teachers, students and teaching methods. All the elements that have been significant and innovative throughout the history inside the teaching process have been analyzed, from the use of blackboard and chalk during lectures, the use of slide projectors and transparent slides, to the use of electronic whiteboards and Internet nowadays. The study is complemented with two types of surveys that have been performed among teachers and students during the school years 1999 - 2011 in the School of Civil Engineering at the Polytechnic University of Madrid. The pros and cons of each of the techniques and methodologies used in the learning process over the last decades are described, unfolding how they have affected the teacher, who has evolved from writing on a whiteboard to project onto a screen, the student, who has evolved from taking handwritten notes to download information or search the Internet, and the educational process, that has evolved from the lecture to acollaborative learning and project-based learning. It is unknown how the process of learning will evolve in the future, but we do know the consequences that some of the multimedia technologies are having on teachers, students and the learning process. It is our goal as teachers to keep ourselves up to date, in order to offer the student adequate technical content, while providing proper motivation through the use of new technologies. The study provides a forecast in the evolution of multimedia within the classroom and the renewal of the education process, which in our view, will set the basis for future learning process within the context of this new interactive era.

Is there scope for a new project bond market in Europe? A promising opportunity for promoting transnational infrastructure

La Unión Europea acaba de lanzar una iniciativa para fomentar Participaciones Público Privadas (PPPs) mediante bonos de proyecto más atractivos a inversores institucionales para promover proyectos transeuropeos. Esto se logra a través de mecanismos de mejora crediticia como garantías de liquidez o tramos de deuda subordinada facilitados por el Banco Europeo de Inversiones. Esta iniciativa pretende evitar los problemas de liquidez experimentados actualmente por bancos comerciales en Europa para financiar megaproyectos. En este artículo exploramos las ventajas e inconvenientes de esta iniciativa para promover redes de infraestructuras transnacionales en Europa, y analizamos su aplicabilidad a otras áreas como Latino-América. The European Union recently launched an initiative to foster Public Private Partnerships (PPPs) for delivering Trans-European projects by making long-term project-bonds more appealing to institutional investors. This is achieved through credit-enhancement mechanisms such as partial stand-by liquidity guarantees, or layers of subordinated debt provided by the European Investment Bank. This initiative intends to circumvent the liquidity problems currently endured by commercial banks in Europe to fund megaprojects. In this paper we explore the advantages and drawbacks of this initiative for promoting transnational infrastructure networks in Europe, and analyse its applicability to other economic areas such as Latin America.

EMBT haciendo (casi) nada en Mercaders = EMBT doing (almost) nothing in Mercaders

Cualquier indagación sobre proyectos representativos en la historia contemporánea de la vivienda, nos lleva inevitablemente a darnos cuenta como predomina en gran parte de ellos una actitud que tiene que ver con producir indiscriminadamente nuevos productos arquitectónicos. EMBT construyen su propia casa en la calle Mercaders de Barcelona, e inciden en entender la arquitectura no como la creación de nuevos productos sino como una capa más dentro de un sustrato ya informado(materia no prima), una característica puramente postproductiva. Como ellos apuntan su nueva capa de información se ‘instala’, añade sólo información precisa de su tiempo, pero no intenta volver hacia atrás ni rehabilitar o restaurar el edificio existente. Esta comunicación persigue poner de manifiesto la existencia velada de esta otra actitud dentro del campo de la vivienda, una actitud no opuesta y si complementaria, que opera desde una voluntad de no ser, de hacer con (casi) nada. ABSTRACT: Any inquiry about representative projects in the contemporary history of housing, lead us to inevitably understand how in lots of them dominates an attitude related to the indiscriminate production of new architectural products. EMBT build their own house on Mercaders street of Barcelona, and promote the understanding of architecture not as the creation of new products but as a new layer within a substrate already full of information (not a raw material), a feature purely postproductive. As they point, the new information layer is ‘installed’, adds only precise information of its time, but does not try to get back or restore the existing building. This paper aims to demonstrate the veiled existence of this different attitude within the housing field, an attitude not opposed but complementary, that works from a desire of not to do, a desire to do with (almost) nothing.

UBURYO: open source software for managing microcredits in education

One of the major problems in developing countries is minority access to higher education. Traditional scholarships usually focus on paying tuition fees for bringing brilliant students to developed countries (from where they seldom return). But local grants seldom target the more needy students. We propose a system of student loans to pay tuition fees in exchange for technical work. This appears to be a satisfactory and sustainable solution. We also provide UBURYO (a Kirundi word meaning opportunity). UBURYO is the free open source software, that we have developed, to manage this loan system in a simple, trustworthy, fair and efficient way.

Evaluation of an application for managing microcredits in education

One of the major problems in developing countries is minority access to higher education. Traditional scholarships usually focus on paying eventually tuition fees or bringing brilliant students to develop countries. Additionally, these systems used to be opaque and, consequently, a corruption source. We propose a system of student loans to pay tuition fees in exchange for work. We also provide UBURYO. It is the FOSS, that we have developed, to manage this loan system in a simple, trustworthy, fair and efficient way. We deployed the loan system in the University of Ngozi (UNG, Burundi). A shallow evaluation demonstrates that system sustainability is feasible.

Construction figures and domestic consumption, which are the most relevant market drivers for forest products, are also significantly better than in the last years. This article analyzes the projections for 2015 in several forest products markets. The conclusion is that a certain general improvement can be expected in most of them, though showing different figures and values.

The use of computers for graduate education in Project Management. Improving the integration to the industry.

This paper presents an initiative for monitoring the competence acquisition by a team of students with different backgrounds facing the experience of being working by projects and in a project. These students are graduated bachelor engineering are inexperienced in the project management field and they play this course on a time-shared manner along with other activities. The goal of this experience is to increase the competence levels acquired by using an structured web based portfolio tool helping to reinforce how relevant different project management approaches can result for final products and how important it becomes to maintain the integration along the project. Monitoring is carried out by means of have a look on how the work is being done and measuring different technical parameters per participant. The use of this information could make possible to bring additional information to the students involved in terms of their individual competencies and the identification of new opportunities of personal improvement. These capabilities are strongly requested by companies in their daily work as well as they can be very convenient too for students when they try to organize their PhD work.

The Economic Value of Residential Land in Historical Areas: An Application of the Residual Method to the Secondary Market

Land value bears significant weight in house prices in historical town centers. An essential aim for regulating the mortgage market, particularly in the financial and property crisis that countries such as Spain are undergoing, is to have at hand objective procedures for its valuation, whatever the conditions (location, construction, planning). Of all the factors contributing to house price make-up, the land is the only one whose value does not depend on acquisition cost, but rather on the location-time binomial. That is to say, the specific circumstances at that point and at the exact moment of valuation. For this reason, the most commonly applied procedure for land valuation in town centers is the use of the residual method: once the selling price of new housing in a district is known, the other necessary costs and expenses of development are deducted, including those of building and the developer’s profit. The value left is that of the land. To apply these procedures it is vital to have figures such as building costs, technical fees, tax costs, etc. But, above all, it is essential to obtain the selling price of the new housing. This is not always feasible, on account of the lack of newbuild development in this location. This shortage of information occurs in historical town cities, where urban renewal is slight due to the heritage-protection policies, and where, nevertheless there is substantial activity in the secondary market. In these circumstances, as an alternative for land valuation in consolidated urban areas, we have the adaptation of the residual method to the particular characteristics of the secondary market. To these ends, there is the proposal for the appreciation of the dwelling which follows, in a backwards direction, the application of traditional depreciation methods proposed by the various valuation manuals and guidelines. The reliability of the results obtained is analyzed by contrasting it with published figures for newly-built properties, according to different rules applied in administrative appraisals in Spain and the incidence of an eventual correction due to conservation state.

Virtual Learning Environments In Faculties Of Education In Spain: Changes On Student Attitude

This paper presents some results of a R+D project entitled “e-Learning system for Practical Training of University students in Education Faculties (ForELearn)”, developed in Spain by the Universidad de Granada and the Universidad Politécnica de Madrid and funded by the Spanish Ministry of Education. In a first phase, through the use of AulaWeb Learning Management System, a set of adaptations and improvements of this software application have been done for the design and development of an experimental course of Practicum supervision. Next, the implementation of this course by means of a group of face to face and online seminars provides experimental data for the analysis and discussion about the point of view of users (preservice teachers) that have tracked their practice supervision with AulaWeb.

WiMAX,Technology and Market.

Wireless communication is the transfer of information from one place to another without using wires. From the earliest times, humans have felt the need to develop techniques of remote communication. From this need arose the smoke signals, communication by sun reflection in mirrors and so on. But today the telecommunications electronic devices such as telephone, television, radio or computer. Radio and television are used for one-way communication. Telephone and computer are used for two-way communication. In wireless networks there is almost unlimited mobility, we can access the network almost anywhere or anytime. In wired networks we have the restriction of using the services in fixed area services. The demand of the wireless is increasing very fast; everybody wants broadband services anywhere anytime. WiMAX (Worldwide Interoperability for Microwave Access) is a broadband wireless technology based on IEEE 802.16-2004 and IEEE 802.16e-2005 that appears to solve this demand. WIMAX is a system that allows wireless data transmission in areas of up to 48 km of radius. It is designed as a wireless alternative to ADSL and a way to connect nodes in wireless metropolitan areas network. Unlike wireless systems that are limited in most cases, about 100 meter, providing greater coverage and more bandwidth. WIMAX promises to achieve high data transmission rates over large areas with a great amount of users. This alternative to the networks of broadband access common as DSL o Wi-Fi, can give broadband access to places quickly to rural areas and developing areas around the world. This paper is a study of WIMAX technology and market situation. First, the paper is responsible for explaining the technical aspects of WIMAX. For this gives an overview of WIMAX standards, physical layer, MAC layer and WiMAX, Technology and Market Beijing University of Post and Telecommunications 2 WIMAX network architecture. Second, the paper address the issue of market in which provides an overview of development and deployment of WIMAX to end the future development trend of WIMAX is addressed. RESUMEN: Por comunicaciones inalámbricas se entiende la transferencia de información desde un lugar a otro sin la necesidad de un soporte físico como es por ejemplo el cable. Por lo que remontándose a los principios de la existencia del ser humano, nos damos cuenta de que el ser humano siempre ha sentido la necesidad de desarrollar técnicas para lograr comunicarse a distancia con sus semejantes. De dicha necesidad, surgieron técnicas tan ancestrales como puede ser la comunicación mediante señales de humo o por reflexión de los rayos solares en espejos entre otras. La curiosidad del ser humano y la necesidad de comunicarse a distancia fue la que llevó a Alexander Graham Bell a inventar el teléfono en 1876. La aparición de un dispositivo que permitía comunicarse a distancia permitiendo escuchar la voz de aquella persona con la que se quería hablar, supuso una revolución no solo en el panorama tecnológico, si no también en el panorama social. Pues a parte de permitir comunicaciones a larga distancia, solventó el problema de la comunicación en “tiempo real”. A raíz de este invento, la tecnología en materia de comunicación ha ido avanzando significativamente, más concretamente en lo referido a las comunicaciones inalámbricas. En 1973 se realizó la primera llamada desde un terminal móvil aunque no fue hasta 1983 cuando se empezó a comercializar dicho terminal, lo que supuso un cambio de hábitos y costumbres para la sociedad. Desde la aparición del primer móvil el crecimiento del mercado ha sido exponencial, lo que ha repercutido en una demanda impensable de nuevas aplicaciones integradas en dichos dispositivos móviles que satisfagan las necesidades que día a día autogenera la sociedad. Tras conseguir realizar llamadas a larga distancia de forma inalámbrica, el siguiente paso fue la creación de los SMS (Short Message System) lo que supuso una nueva revolución además de abaratar costes al usuario a la hora de comunicarse. Pero el gran reto para la industria de las comunicaciones móviles surgió con la aparición de internet. Todo el mundo sentía la necesidad de poder conectarse a esa gran base de datos que es internet en cualquier parte y en cualquier momento. Las primeras conexiones a internet desde dispositivos móviles se realizaron a través de la tecnología WAP (Wireless Application Protocol) hasta la aparición de la tecnología GPRS que permitía la conexión mediante protocolo TCP/IP. A partir de estas conexiones han surgido otras tecnologías, como EDGE, HSDPA, etc., que permitían y permiten la conexión a internet desde dispositivos móviles. Hoy en día la demanda de servicios de red inalámbrica crece de forma rápida y exponencial, todo el mundo quiere servicios de banda ancha en cualquier lugar y en cualquier momento. En este documento se analiza la tecnología WiMAX ( Worldwide Interoperability for Microwave Access) que es una tecnología de banda ancha basada en el estándar IEEE 802.16 creada para brindar servicios a la demanda emergente en la banda ancha desde un punto de vista tecnológico, donde se da una visión de la parte técnica de la tecnología; y desde el punto de vista del mercado, donde se analiza el despliegue y desarrollo de la tecnología desde el punto de vista de negocio. WiMAX es una tecnología que permite la transmisión inalámbrica de datos en áreas de hasta 48Km de radio y que está diseñada como alternativa inalámbrica para ADSL y para conectar nodos de red inalámbrica en áreas metropolitanas. A diferencia de los sistemas inalámbricos existentes que están limitados en su mayoría a unos cientos de metros, WiMAX ofrece una mayor cobertura y un mayor ancho de banda que permita dar soporte a nuevas aplicaciones, además de alcanzar altas tasas de transmisión de datos en grandes áreas con una gran cantidad de usuarios. Se trata de una alternativa a las redes de acceso de banda ancha como DSL o Wi-Fi, que puede dar acceso de banda ancha a lugares tales como zonas rurales o zonas en vías de desarrollo por todo el mundo con rapidez. Existen dos tecnologías de WiMAX, WiMAX fijo (basado en el estándar IEEE 802.16d-2004) y WiMAX móvil (basado en el estándar IEEE 802.16e-2005). La tecnología fija está diseñada para comunicaciones punto a multipunto, mientras que la fija lo está para comunicaciones multipunto a multipunto. WiMAX móvil se basa en la tecnología OFDM que ofrece ventajas en términos de latencia, eficiencia en el uso del espectro y soporte avanzado para antenas. La modulación OFDM es muy robusta frente al multitrayecto, que es muy habitual en los canales de radiodifusión, frente al desvanecimiento debido a las condiciones meteorológicas y frente a las interferencias de RF. Una vez creada la tecnología WiMAX, poseedora de las características idóneas para solventar la demanda del mercado, ha de darse el siguiente paso, hay que convencer a la industria de las telecomunicaciones de que dicha tecnología realmente es la solución para que apoyen su implantación en el mercado de la banda ancha para las redes inalámbricas. Es aquí donde entra en juego el estudio del mercado que se realiza en este documento. WiMAX se enfrenta a un mercado exigente en el que a parte de tener que dar soporte a la demanda técnica, ha de ofrecer una rentabilidad económica a la industria de las comunicaciones móviles y más concretamente a las operadoras móviles que son quienes dentro del sector de las telecomunicaciones finalmente han de confiar en la tecnología para dar soporte a sus usuarios ya que estos al fin y al cabo lo único que quieren es que su dispositivo móvil satisfaga sus necesidades independientemente de la tecnología que utilicen para tener acceso a la red inalámbrica de banda ancha. Quizás el mayor problema al que se ha enfrentado WiMAX haya sido la situación económica en la que se encuentra el mundo. WiMAX a comenzado su andadura en uno de los peores momentos, pero aun así se presenta como una tecnología capaz de ayudar al mundo a salir hacia delante en estos tiempos tan duros. Finalmente se analiza uno de los debates existentes hoy en día en el sector de las comunicaciones móviles, WiMAX vs. LTE. Como se puede observar en el documento realmente una tecnología no saldrá victoriosa frente a la otra, si no que ambas tecnologías podrán coexistir y trabajar de forma conjunta.

Evaluation of the trading development in the Iberian Energy Derivatives Market

The efficiency of the Iberian Energy Derivatives Market in its first five and a half years is assessed in terms of volume, open interest and price. The continuous market shows steady liquidity growth. Its volume is strongly correlated to that of the Over The Counter (OTC) market, the amount of market makers, the enrolment of financial agents and generation companies belonging to the integrated group of last resort suppliers, and the OTC cleared volume in its clearing house. The hedging efficiency, measured through the ratio between the final open interest and the cleared volume, shows the lowest values for the Spanish base load futures as they are the most liquid contracts. The ex-post forward risk premium has diminished due to the learning curve and the effect of the fixed price retributing the indigenous coal fired generation. This market is quite less developed than the European leaders headquartered in Norway and Germany. Enrolment of more traders, mainly international energy companies, financial agents, energy intensive industries and renewable generation companies is desired. Market monitoring reports by the market operator providing post-trade transparency, OTC data access by the energy regulator, and assessment of the regulatory risk can contribute to efficiency gains.

Systems in Engineering Education: account of an experience

Systems Engineering (SE in the following) has not received much attention as a subject matter in engineering curricula. There are several dozens of universities around the world offering programs (most of them at the graduate level) on systems science and engineering. However, SE is, per se, rarely found among the courses offered by engineering schools. This observation does not strictly mean that systems concepts be left apart. For example, it is usual to find specialized courses for systems of some particular classes (e.g., courses on software systems engineering for computing curricula) or for particular phases of the system life cycle (e.g., courses on systems analysis). Even so, these kinds of courses tend to over-emphasize the importance of specific methodologies and, in consequence, to deviate the attention from the realm of systernness

How future trends may affect international cooperation in planning education : the case of Spain and Latin America

Despite the benefits for exc hanging experiences among planners at the global scale, the strong context dependency of urban planning creates in many instances significant difficulties to extrapolate experiences from one geographical context to the other. If progress is to be achieved in international cooperation programmes, differences and commonalities should be assessed before la unching any academic initiative. In that respect, this p aper makes a brief foresight exercise on how future trends and challenges, which may affect the urban pl anning field, should be taken into consideration according to two different contexts: Spain and Latin America. A segmentation matrix is used to expose a nd discuss the different effects of future trends on both contexts. Some tentative conclusions are drawn for the development of international educational programmes
